The PLC control module 31 is used for receiving a rotation state signal of the forward and reverse rotation motor 32 and transmitting the rotation state signal to the electrified contact controller 34, the electrified contact controller 34 is used for controlling the power supply of the power supply 33 when the separation wheel 2 rotates normally and blocking the power supply of the power supply 33 when the separation wheel 2 rotates blocked, and the PLC control module 31 sends an instruction to the electrified contact controller 34 and the forward and reverse rotation motor 32 simultaneously after receiving the power supply signal blocked by the power supply 33 so as to switch on the power supply 33 for the second time and control the forward and reverse rotation motor 32 to rotate reversely.

The embodiment of the invention mainly aims at solving the problems that the power supply of the discharger is in power failure and the equipment cannot normally run due to the fact that a separating wheel is easily clamped by a large material in the feeding process of gypsum board production. The embodiment mainly solves the problem of material clamping and electricity jumping by controlling the positive and negative rotation of the motor and assisting the rapping mechanism. The main process for finishing one-time material blocking treatment is as follows:

the operation of the equipment is blocked because the separation wheel 2 is blocked by the massive material, the power-on contact controller 34 controls the power supply 33 to be powered off and sends a power supply blocking signal to the PLC control module 31, the PLC control module 31 receives the power supply blocking signal and then sends an instruction to the positive and negative rotation motor 32 and the power-on contact controller 34 simultaneously, the power supply 33 is controlled by the power-on contact controller 34 to be powered on, the positive and negative rotation motor 32 rotates reversely, the rapping mechanism 6 raps the discharger, the blocked material is shaken off, and the equipment is enabled to recover the normal operation.

Through the mode of above automatic clearance card material, need not separate at every turn that the round card material jumps the electricity back, clear up the material earlier, artifical distribution power transmission again, the positive and negative automatic clearance of equipment control motor blocks the material, changes and reduces the bad influence of jumping the electricity trouble to frying material efficiency, improves production efficiency.

The tripper is the main equipment of dust collecting equipment, air supply and other equipment feeds, unloading, is applicable to powder and granular material, consequently has higher requirement to the leakproofness, because nevertheless the main shaft both ends in the lock wind tripper pass the casing installation mostly, leaks the material easily to take place in tripper lateral wall installation department. For this reason, the present embodiment provides a sealing structure at the installation place of the divider wheel to improve the sealing performance of the discharger.

In the embodiment, the rotating shaft 21 of the separating wheel 2 is arranged on the side wall of the discharger main body 1 through the sealing connection structure 4, the end part of the rotating shaft 21 penetrating through the outer part of the discharger main body 1 is provided with a coupling structure 5, and the coupling structure 5 is connected with a vibrating mechanism 6; the sealing connection mechanism 4 is used for connecting the rotating shaft 21 on the discharger main body 1 in a sealing way, and the coupling mechanism 5 is used for driving the vibration mechanism 6 to vibrate the discharger main body 1.

And the reason that the separation wheel is blocked to the material of commonly used tripper lies in that the material granule is great to block easily between the impeller of separation wheel on the one hand, on the other hand uses rotor axial lead to carry out the immobilization rotation as the center usually in the tripper, and the position of impeller is fixed, can't shake oneself and increase the card material degree of difficulty. Therefore, the sealing connection mechanism 1 in the present embodiment not only can be used for sealing the rotating shaft 21 to improve the sealing performance of the discharger, but also can drive the impeller to move in the radial direction when the impeller rotates along with the rotating shaft 21, rather than only rotating around the fixed axis fixedly as in the conventional way.

Vibrating mechanism 6 plays the effect of the blanking of shaking to the tripper, if set up vibrating mechanism 6 inside the tripper that locks the wind, the easy joint adhesion material on vibrating mechanism 6 leads to weakening and shakes the effect.

Therefore, in the present embodiment, when the rotating shaft 21 rotates around its long axis, the inner wall of the rotating sleeve 422 closely contacts the rotating shaft 21 and rotates, and one side wall of the rotating sleeve 422 closely contacts the surface of the seal ring plate 421 and slides, so that the position of the rotating sleeve 422 changes according to the rotation angle of the rotating shaft 422.

In order to facilitate the installation and reduce the adhesion between the material and the material in the main body of the discharger 1, further, the sealing gasket disc 421 adopts the following embodiments:

the sealing gasket disc 421 comprises a sealing disc body 4211, a groove 4212 and a movable cavity 4213 which are arranged on the sealing disc body 4211; the sealing disc 4211 is fixed on the inner wall of the discharger main body 1 and is coaxially and fixedly connected with the second shaft sleeve 412, and the end part of the second shaft sleeve 412, which is positioned inside the discharger main body 1, penetrates through the sealing disc 4211 and is exposed in the groove 4212;

Since the sliding shaft 423 is pressed against the surface of the rotating sleeve 422 by the spring 424, when the rotating sleeve 422 rotates, the sliding shaft 423 reciprocates in the movable chamber 4213 under the action of the spring, automatically adjusts the contact point of the rotating sleeve 422 and the outer surface of the second sleeve 412 under the action of the eccentric force, and is driven to rotate eccentrically again at each contact.

In order to cooperate with the eccentric rotation of the rotating shaft sleeve 422, the present embodiment provides an implementation manner of the divider wheel 2, that is, a fixed net 23 is arranged on the rotating shaft 21, two ends of the fixed net 23 are respectively connected to the rolling shaft sleeve 422, and the rotating impellers 22 are uniformly arranged in the fixed net 23; the fixed net 23 can move axially along the rotary impeller 22 under the action of external force, and the rolling shaft sleeve 422 eccentrically rotates to drive the fixed net 231 to axially slide back and forth along the rotary impeller 22.

Rotatory impeller receives on the one hand to rotate the influence, and on the other hand receives material gravity extrusion influence, if let rotatory impeller freely move in footpath, is unfavorable for stabilizing the unloading, consequently reverse consideration radial fine motion problem, by the radial fine motion of fixed net 23, the material that supplementary clearance blocked. Consequently, fixed net 231 is driven eccentric rotation by rotatory axle sleeve down, shows for following rotatory impeller 22 length direction friction back and forth movement, reduces the material of adhesion on the rotatory impeller 22 blade, if there is the bold material card when between rotatory impeller 22, the material can be strikeed in the removal to the fixed net 23 of round trip movement, reduces the material volume, and the material that conveniently blocks drops as early as possible, improves the efficiency of cleaning up the material. In addition, the blades of the rotary impeller 22 can adopt a fine mesh structure, so that not only can the material blocks be clamped in a vibration mode, but also larger material blocks can be screened and refined, and the blanking is stabilized.

Because the unloading core rotates for axis of rotation 21 in the tripper main part 1, supplementary shaking and falling the vibration mechanism 6 setting of joint material piece outside the tripper main part 1 in this embodiment to prevent that the adhesion material influences and shakes the effect of beating. Considering that the rotating shaft 21 and the rotating shaft sleeve 422 in the discharger main body 1 drive the separation wheel 2 to rotate and slightly move, the vibration mechanism 6 is driven by the coupling mechanism 5 to synchronously cooperate with the action in the discharger main body 1, and the specific implementation is as follows:

the coupling mechanism 5 comprises a spiral rotating shaft 51, a limiting plate 52 and a rotary internal drive compass 53, wherein the limiting plate 52 and the rotary internal drive compass 53 are arranged on the spiral rotating shaft 51, one end of the spiral rotating shaft 51 is mounted on a first shaft sleeve 411, the spiral rotating shaft 51 can rotate in the first shaft sleeve 411, spiral tooth marks are arranged on the surface of the spiral rotating shaft 51, and tooth marks matched with the spiral tooth marks are arranged on the side wall of an inner ring of the rotary internal drive compass 53 to support the rotary internal drive compass 53 to rotatably slide on the spiral rotating shaft 51. The limit plate 52 is coaxially fixed on the rotating shaft 51, and the rotary internal drive compass 53 is sleeved on the spiral rotating shaft 51 and is driven by external force to rotate and slide on the spiral rotating shaft 51. The rotary inner drive compass 53 moves from the side close to the discharger main body 1 toward the stopper plate 52 side on the compass rotary shaft 51, and can return when it hits the stopper plate 52, thereby performing reciprocating rotational movement.

Wherein, the rotary internal drive compass 53 is connected with the sliding shaft 423 through the linkage shaft bracket 54, one end of the vibration mechanism 6 is fixed on the rotary internal drive compass 53, and the vibration mechanism 6 raps the side wall of the discharger body 1 under the driving of the motor when the rotary internal drive compass 53 rotates and slides once.

The slide shaft 423 moves upward for a half cycle of a reciprocating cycle, and the rotary inner drive compass 53 moves leftward (i.e., in a direction from the discharger body side toward the limit plate) for a half cycle of a cycle of the rotary inner drive compass 53. The sliding shaft 423 moves upward, a force is applied to the driving ring 541 through the supporting rod 542 to push the driving ring 541 leftward, the rotating internal drive compass 53 is naturally pushed to move leftward as the rotating internal drive compass 53 is arranged on the left side of the driving ring 541, the sliding shaft 423 moves upward to the one-way end point, the rotating internal drive compass 53 meets the limiting plate 52, and the leftward movement is stopped. The sliding shaft 423 moves back and forth downwards under the action of the spring 424, force is applied to the driving ring 541 through the straight rod 542, the driving ring 541 is pushed rightwards, and the rotating inner drive compass 53 is driven by the driving ring 541 to move backwards towards the right due to the fixed connection of the rotating inner drive compass 53 and the driving ring 541.
