as shown in fig. 1 and 3, the present invention provides a pulp feeding apparatus, which mainly comprises: a pulp roll 1, a first tank 2, a second tank 3 and a frame 8. The positions of the paper pulp roll 1 in the feeding device are sequentially an A station, a B station, a C station and a D station from left to right, and the flow path directions of the paper pulp 18 are sequentially e, f, g and h from top to bottom. As shown in fig. 3, for convenience of explanation, the direction indicated by the arrow M is set as the flow direction of the apparatus, and both sides of the feeding device are divided into R-side and L-side. The station A and the station B of the paper pulp feeding device are both the uncoiling positions of the paper pulp material coil 1, when the device operates, one station is normally uncoiled, the other station is standby, namely when the station A is uncoiled as the paper pulp material coil 1, the station B is standby, and when the station B is uncoiled as the paper pulp material coil 1, the station A is standby. The pulp material rolls 1 of the station A and the station B are respectively provided with two material loading flow paths, namely the station A can carry out material loading according to the flow paths e and f; and the station B can carry out feeding according to flow paths g and h. If the paper pulp 18 unwound from the paper pulp roll 1 in the station A travels according to the flow path f when the station A and the station B are both in a full state of the paper pulp roll 1, the paper pulp 18 of the paper pulp roll 1 in the station B travels according to the flow path h, and the travel of the flow path ensures that the used materials and the standby materials are unwound independently without mutual influence. In another flow path, when the pulp 18 unwound from the pulp roll 1 in the station B travels along the flow path e, the pulp 18 of the pulp roll 1 in the station a travels along the flow path g. In specific implementation, the flow path can be selected according to the material using conditions of the pulp material roll 1 at the A station and the B station. In order to form the flow paths g and h, a tray 9 is fixedly provided on the downstream side of the frame 8, and a plurality of drawing rolls 17 are provided on the tray 9 to form a running path of the pulp 18 unwound from the pulp roll 1.

As shown in fig. 7, in the direction of the flow M, the initial position of the first groove 2 is set as a, and the end position is set as b; the start position of the second groove 3 is set to j and the end position is set to k. As shown in fig. 3-4, the first groove 2 is composed of two first stoppers 2-1 symmetrical to each other and a first plate 2-2 at the bottom thereof, and the two first stoppers 2-1 are respectively located at the left and right sides above the first plate 2-2. As shown in FIG. 7, when the width of the starting position a of the first groove 2 is W1 and the width of the end position B of the first groove 2 is W2, W1 > W2.

It should be noted that the deviation detecting sensor is used for giving an alarm or stopping the machine when the deviation of the pulp 18 exceeds the theoretical position by more than 5mm, and confirming whether the deviation of the placing position of the pulp 18 occurs. The material breakage detection is that after the paper pulp 18 on the paper pulp roll 1 is used up, the material breakage detection sensor detects that the paper pulp 18 is used up, the station A/B is switched to the station B/A under the control of a program, and meanwhile, the next action is manually carried out; the small-diameter detection sensor can be used for preparing feeding to the station D when the station A or the station B has one pulp material roll 1 for prompting a small-diameter alarm, and when the station A and the station B simultaneously prompt that the two pulp material rolls 1 have the small-diameter detection alarm, the pulp material rolls 1 of the two stations are in a condition of less pulp, and the feeding is required immediately. When the small diameter of the pulp material roll 1 at the station A or the station B is detected continuously for a period of time (can be set by a program), or two material breakage detections occur simultaneously, the shortage of the materials occurs at the moment, and the equipment is automatically stopped.

the main working flow of the paper pulp feeding device of the invention is as follows:

Inserting the mandrel 10-1 into the pulp roll 1: loosening the fastening bolt of the bearing inner sleeve 10-2 at one side of the mandrel 10-1, detaching the first bearing 10-3 and the second bearing 10-4 at one side of the mandrel 10-1, loosening and detaching the material stop block 15 at the side, removing the core of the used pulp roll 1 on the mandrel 10-1, penetrating the mandrel 10-1 into the core of a new pulp roll 1, enabling the pulp roll 1 to be at the middle position of the mandrel 10-1, installing and fastening the material stop block 15 at the side, sleeving the bearing inner sleeve 10-2 with the first bearing 10-3 and the second bearing 10-4, attaching the shaft end face, screwing the fastening bolt of the bearing inner sleeve 10-2, and completing the process of inserting the pulp roll 1 into the mandrel 10-1.

Feeding, the pulp roll 1 is sent to a station D and a station C: the fourth cylinder 14-4 is activated to retract the piston rod of the fourth cylinder 14-4, so that the first groove 2 carried by the adjusting plate 4 is in an inclined position. And simultaneously retracting a piston rod of the third air cylinder 14-3 to lower the sixth baffle 11-6, and placing the shaft 10 of the pulp roll 1 to a station D through a forklift, wherein a first groove 2 which is narrowed from wide is arranged at the station D, so that the first bearing 10-3 of the shaft 10 filled with new materials is placed in the first groove 2. After the shaft 10 is placed in the station D, under the action of gravity, the first bearing 10-3 rolls to the starting end a of the first groove 2 and is positioned by the first baffle 11-1. At this time, the third cylinder 14-3 is actuated to extend the piston rod of the third cylinder 14-3, so that the sixth shutter 11-6 is lifted, and the shaft member 10 is retained at the first groove start end a of the station D. Then the fourth cylinder 14-4 is started again, the shaft 10 raises the first tank 2 to the horizontal position under the action of the fourth cylinder 14-4, at which point the feeding process of the shaft 10 with the new pulp roll 1 is completed, and the pulp roll 1 reaches the station C.

feeding from station C to station B: and starting the second air cylinder 14-2, extending a piston rod of the second air cylinder 14-2, lifting the fifth baffle plate 11-5, descending the second baffle plate 11-2 to a second position 11-8, simultaneously descending the sixth baffle plate 11-6, manually pushing the shaft 10, slowly moving the shaft 10 with the pulp roll 1 from the station C to the station B, and simultaneously ensuring the central position of the pulp roll 1 to be at the theoretical center under the action of the narrowing of the first groove 2. When reaching the end B of the first vat 2, the second bearing 10-4 rolls into the track of the second vat 3 and finally stops in the way of the fifth apron 11-5, which lifts the second apron 11-2 to the first position 11-7, so that the pulp roll 1 is completely positioned in station B.

When station a pulp roll 1 is exhausted, feed from station B to station a: the first air cylinder 14-1 is started, the piston rod of the first air cylinder 14-1 is extended, the fourth baffle 11-4 is lifted, the third baffle 11-3 is descended to the second position 11-8, the second air cylinder 14-2 is closed, the fifth baffle 11-5 is descended, the shaft 10 is manually pushed, the shaft 10 filled with the new pulp roll 1 is slowly moved from the station B to the station A, the width of the second groove 3 is basically consistent with the width of the second bearing 10-4, and the central position of the pulp roll 1 is ensured at the theoretical center. Finally, it stops under the action of the fourth flap 11-4, whereupon the third flap 11-3 is lifted to the first position 11-7, so that the roll of pulp material 1 is positioned completely in station a.

The above steps are repeated to position the pulp roll 1 in station B.

taking an empty roll core: and when the use of the pulp roll 1 in the station A is finished, the fourth baffle 11-4 is descended, the empty roll core is taken down from the left side, the station A is vacated, and the station A feeding step is repeated.

after the feeding is finished, the pulp rolls (1) at the A station and the B station are respectively discharged to a first path L1 and a second path L2 at the downstream side along flow paths e/f and g/h.

The action sequence is as follows: the sleeving shaft 10-1 → the feeding station D → the raising to the station C → the station B emptying → the pulp roll 1 moves from the station C to the station B → the pulp 18 running direction e (simultaneous threading) → the station a emptying → this time the station B pulp running feed → the pulp roll moves from the station B to the station a → the pulp running direction f → the pulp roll 1 of the station a runs out after it runs out → the empty core is taken → the next step of turn → the sleeving shaft 10-1 → the feeding station D → the raising to the station C → the station B emptying → the pulp roll 1 moves from the station C to the station B → the pulp 18 running direction h (simultaneous threading) → the station a emptying → this time the station B pulp running feed → the pulp roll 1 moves from the station B to the station a → the pulp 18 running direction g → the station a pulp roll 1 runs out after it runs out → the empty core → the next step of turn → the cycle.

It should be noted that, in the pulp feeding device, since the pulp roll 1 is not driven, the pulp roll 1 is pulled to rotate by the pulling force of the pulp, in order to prevent the pulp roll 1 from continuously rotating to cause the pulp to loosen and drop under the action of inertia force when the device is stopped, the core shaft 10-1 needs to be fixed in the first groove 2 or the second groove 3, the pulp roll 1 and the core shaft 10-1 are allowed to rotate relatively, the friction force of the rotation is increased, and when the pulp roll 1 has no pulling force, the pulp roll 1 can be quickly stopped to rotate.

the pulp feeding device adopts a feeding mode of supporting the mandrel at two ends, has obvious advantages, and has larger change of deformation generated by stress of the mandrel 10-1 compared with the traditional single-arm support.

It can be seen from formula 1 and formula 2 that the deformation amount, i.e. deflection, of the gravity point of the pulp can be significantly reduced by changing from single cantilever support to double cantilever support under the same conditions (same pulp load P and distance l), and the deflection of the mandrel 10-1 is 3/48 of single cantilever support by adopting the mode of supporting the mandrel 10-1 at two ends, because in the calculation formula, the elastic modulus E is determined by the pulp, so that the elastic modulus E is kept constant, the axial inertia moment I of the cross section is constant, the concentrated load P (pulp gravity) is constant, the length l is constant, and the deflection of the gravity point of f _c is changed into 3/48 of single cantilever support, i.e. f _c is f _A 3/48, so that the pulp feeding device adopts the mode of supporting the mandrel 10-1 at two ends, thereby significantly reducing the bending deformation amount of the mandrel 10-1 under load, and prolonging the service life of the mandrel.
