Detailed Description

The present invention is further illustrated by the following description in conjunction with the accompanying drawings, which are to be construed as merely illustrative and not limitative of the remainder of the disclosure, and on reading the disclosure, various equivalent modifications thereof will become apparent to those skilled in the art and fall within the limits of the appended claims.

As shown in fig. 1-6, the distributor comprises a discharge assembly 1, a rotary distribution member 2, a rotary air duct 3, and a feeding member 4.

As shown in fig. 2-5, the discharging assembly comprises a cylinder 11, a partition plate 12 and a support base 13.

The cylinder 11 is provided with a first connecting flange 110. The support base 13 is located at the center of the cylinder 11. The barrel 11 and the supporting seat 13 are provided with spoke-shaped partition plates 12, the partition plates 12 are in the shape of a ridge, and the barrel 11 is divided into a plurality of conical discharging cavities 10 by the partition plates 12. Because the connection between adjacent conical discharging cavities 10 is only the thickness of the wall plate of the conical discharging cavity, namely the partition plate 12, the material accumulation on the inner side of the conical discharging cavity 10 is avoided.

As shown in fig. 1, 2 and 6, the rotary material-separating part 2 includes a rotary feeding pipe 20, a fixing device 21, a main shaft 23, a first coupling 25, a second coupling 24 and a speed-reducing motor 26. The speed reducing motor 26 is mounted on the bracket 5, the speed reducing motor 26 is connected with the main shaft 23 through the first coupling 25 and the second coupling 24, and the main shaft 23 is supported through the first bearing with seat 27 and the second bearing with seat 28. The first coupling 24, the second coupling 25 and the second rolling bearing 28 are arranged in the support base 13. The first pedestal bearing 27 is provided on the support base 13, and the seal cap 22 is provided on the first pedestal bearing 27.

Under the drive of the speed reducing motor 26, the rotary feeding pipe 20 rotates around the circumference of the main shaft 23 at a uniform speed without stopping, and the feeding part 4 feeds materials to uniformly distribute the materials to the conical discharging cavities 10 uniformly distributed on the circumference.

As shown in FIG. 6, the rotary feeding pipe 20 comprises an inlet 201, an inclined section 202 and an outlet 203 which are connected in sequence, wherein the inlet 201 is arranged coaxially with the feeding part 4, and the central axes of the inlet 201 and the outlet 203 are arranged vertically. The inclined section 202 is arranged inclined downwards with respect to the inlet 201.

The shell 6 is arranged outside the rotary feeding pipe 20, and a second connecting flange 61 is arranged on the shell 6. The second connecting flange 61 on the cover 6 is bolted to the first connecting flange 110 on the barrel 11.

The outlet 203 of the rotary feed conduit 20 is of a conical configuration, preferably a non-straight conical configuration. The taper of the outlet 203 of the rotary feeding pipe 20 at the side of the housing 6 is smaller than that of the outlet 203 of the rotary feeding pipe 20 at the side of the main shaft 23.

In the axial section of the outlet 203 of the rotary feeding pipe 20, the included angle between the bus at the side of the housing 6 and the lower bottom is alpha, and alpha is more than or equal to 55 degrees and less than 90 degrees; the included angle between the bus on the main shaft side and the lower bottom is beta, and beta is more than or equal to 55 degrees and less than 90 degrees. The relationship between α and β, preferably α ≧ β.

The setting of the angle alpha has two functions: firstly, in the material distributing process, the outlet of the feeding pipe 20 is convenient to rotate to directly feed the materials to the central position of the discharging cavity 10, so that the materials are prevented from accumulating inside the discharging cavity 10; secondly, in the cleaning stage, the high-pressure airflow in the rotary air duct 3 is guided into the discharging cavity 10.

The angle beta is convenient for rotating the outlet of the feeding pipe 20 to directly feed the materials to the central position of the discharging cavity 10, so that the materials are prevented from accumulating on the supporting seat 13.

Preferably, in the rotary feed pipe 20, the side wall of the outlet 203 on the main shaft 20 side is extended outward relative to the side wall of the main shaft side inclined section 202, so that the discharge amount of the outlet is increased.

Because the connection between the adjacent conical discharging cavities 10 is only the thickness of the wall plate of the conical discharging cavity, namely the partition plate 12, and simultaneously has an ideal material self-flowing angle, the outlet of the rotary feeding pipe 20 at the side of the housing 6 forms an angle alpha so as to prevent the materials from accumulating at the inner side of the cylinder body of the conical discharging cavity 10 and directly throw the materials to the central position of the outlet of the discharging cavity 10. The outlet 203 of the rotary feeding pipe 20 on the side of the vertical shaft 23 forms an angle beta to avoid material accumulation on the supporting seat 13, and the material is directly fed to the central position of the outlet of the discharging cavity 10 to avoid residue and material accumulation.

The feeding component 4 is rotatably connected with the inlet 201 of the rotary feeding pipe 20, and a sealing member is arranged between the feeding component 4 and the inlet 201 of the rotary feeding pipe 20.

As shown in fig. 1, 2 and 6, the rotary air duct 3 includes a first confluence air baffle plate 31 and a second confluence air baffle plate 32, and the first confluence air baffle plate 31 and the second confluence air baffle plate 32 are disposed on the rotary feeding pipe 20.

The first confluence wind shielding plate 31 and the second confluence wind shielding plate 32 are arranged along the length direction of the rotary feeding pipe 20, and gaps are reserved between the first confluence wind shielding plate 31 and the housing 6 and between the second confluence wind shielding plate 32 and the housing 6. The first and second confluence wind guard plates 31 and 32 are arranged in parallel. The first confluence wind shield 31 and the second confluence wind shield 32 are matched with the rotary feeding pipe 20. The space enclosed by the first confluence wind shield 31, the second confluence wind shield 32, the rotary feeding pipe 20, the housing 6 and the feeding component 4 forms a rotary air duct 3. The housing 6 or the feeding part 4 is provided with a plurality of high-pressure air source interfaces 33 which are distributed along the periphery of the feeding part 4. The high-pressure air source interface 33 is provided with an electromagnetic valve which is connected with the PLC control unit 30. The PLC control unit 30 controls the on-off state of the high-pressure air source interface 33 according to the set frequency and requirements, and independently or a plurality of high-pressure air source interfaces 33 are opened. The rotary feeding pipe 20 is infinitely positioned below the plurality of high-pressure air source interfaces 33 uniformly distributed along the circumference of the feeding part 4 in the rotating process, when the first confluence wind shield 31 approaches one high-pressure air source interface 33 in the rotating process, the corresponding high-pressure air source interface is started by the electromagnetic valve, when the first confluence wind shield 32 leaves the high-pressure air source interface 33, the corresponding high-pressure air source interface is started by the electromagnetic valve, meanwhile, the second high-pressure air source interface 33 is started by the electromagnetic valve, and the plurality of high-pressure air source interfaces 33 uniformly distributed along the circumference of the feeding part 4 or the housing 6 are continuously, repeatedly started and closed in turn, so that the first and second confluence wind shields 31 and 32 above the rotary feeding pipe 20 are arranged at any position, high-pressure air flow exists in the rotary air duct, and the aim of cleaning is fulfilled.

The matching of a plurality of high-pressure air source interfaces and a single rotary air duct can be realized by the following means: according to the set relative position of the rotating speed of the main shaft and the high-pressure air source interface, calculating the time required for the rotary feeding pipe to rotate to the position near the corresponding high-pressure air source interface through the rotating speed of the main shaft, and writing the corresponding opening time of the electromagnetic valve into the PLC program control, so that when the electromagnetic valve is opened, the rotary air channel is matched with the corresponding high-pressure air source interface, and the high-pressure cleaning function is realized; the method specifically comprises the following steps:

a proximity switch is arranged near one of the high-pressure air source interfaces 33 and is connected with the PLC control unit 30 through a control line. The first and second bus windshield plates 31 and 32 are metal detection bodies. When the first and second confluence wind deflectors 31 and 32 are close to the induction area of the proximity switch, the proximity switch can send out an electric command rapidly without contact, pressure and spark, and accurately reflect the position and the stroke of the motion mechanism;

when the proximity switch is turned on and the feeding pipe 20 is detected to be rotated to the high-pressure air source interface 33, the PLC control unit 30 controls T₀Opening the high-pressure air source interface electromagnetic valve at any moment, and controlling the electromagnetic valve to open for 1-3 seconds; according to the set main shaft rotating speed and the position of the high-pressure air source interface, the position is knownOpening time T of one high-pressure air source interface₀Opening time T of other i high-pressure air source interfaces_iAnd T₀Time difference Δ t therebetween_iIs calculable. PLC control unit according to T₀、Δt_iDetermining other high-pressure air source interfaces T_iAnd sequentially starting and closing the high-pressure gas source switch electromagnetic valves which are circumferentially arranged, and continuously inputting high-pressure gas to the rotary air duct.

The cooperation of a plurality of high-pressure air source interfaces with a single rotating air duct can also be realized by other prior art means.

The material distributor divides the material theory of operation:

as shown in fig. 2, a speed reduction motor 26 mounted on the bracket 5 drives a first coupling 25, the first coupling 25 drives a second coupling 24, the second coupling 24 drives a main shaft 23, the main shaft 23 is fixed to a connecting and fixing device 21, and the fixing device 21 is connected to the rotary feeding pipe 20. Under the drive of the speed reducing motor 26, the rotary feeding pipe 2 rotates around the circumference of the main shaft 23 in the vertical direction at a uniform speed without stopping, and the feeding part 4 feeds materials to realize uniform distribution of the conical discharging cavities 101, 102 and 103 which are uniformly distributed on the circumference.

Because the connection between adjacent conical discharging cavities 10 is only the thickness of the wall plate of the conical discharging cavity, namely the partition plate 13, and simultaneously has an ideal material self-flowing angle, the outlet 203 of the rotary feeding pipe at the side of the housing 6 forms an angle alpha, and the material is directly thrown to the center of the outlet, so that the material accumulation at the inner side of the conical discharging cavity is avoided. The outlet 203 of the rotary feeding pipe on the main shaft side forms an angle beta, and the material is directly fed to the center of the outlet, so that the material is prevented from accumulating on the supporting seat 13.

The self-cleaning working principle of the distributor is as follows:

as shown in fig. 2, the feeding pipe 20 is rotated for 5 to 10 minutes in a feeding stop state, i.e., after the feeding of the feeding port is stopped. And (3) opening a proximity switch A, B, detecting that the feeding pipe 20 is rotated, and sequentially starting and closing a solenoid valve switch of a high-pressure air source interface according to a set frequency to input high-pressure air for the rotating air duct. The PLC control unit 30 opens and closes the high-pressure air source interfaces 33 distributed along the circumference of the periphery of the feeding part 4 independently or a plurality of high-pressure air source interfaces 33 are opened, the rotary feeding pipe 20 is positioned below the high-pressure air source interfaces 33 uniformly distributed along the circumference of the feeding part 4 for an unlimited number of times in the rotating process, when the first confluence wind shield 31 approaches one high-pressure air source interface 33 in the rotating process, the electromagnetic valve starts the corresponding air source to be opened, the first confluence wind shield 32 leaves the high-pressure air source interface 33 for a time, the electromagnetic valve starts the corresponding air source to be closed, the electromagnetic valve starts the second high-pressure air source interface 33 at the same time, and the high-pressure air source interfaces 33 uniformly distributed along the circumference of the feeding part 4 are continuously and repeatedly started and closed in turn, so that the first confluence wind shield 31 and 32 on the rotary feeding pipe 20 are arranged at any position, high-pressure airflow exists in the rotary air duct. The effective space distance between the first confluence wind boards 31 and the second confluence wind boards 32 on the two sides of the upper surface of the rotary feeding pipe 20 and the housing 6 is utilized to form waterfall type high-pressure airflow moving downwards along the housing 6, and the high-pressure airflow forms spiral waterfall type high-pressure airflow under the rotation of the rotary feeding pipe 20 to effectively clean the conical discharging cavities 101, 102 and 103, so that the conical discharging cavities 101, 102 and 103 of the conical discharging cavities are cleaned without residues. The measures can completely ensure cleanness and sanitation for the feed without residue and material accumulation.
