[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of the present application.

[0024] As shown in the drawings, Figures 1-8 A pulp board winding and packing device includes a two-layered annular paper guiding belt 5, which includes a paper guiding area 1, a running area 4, a paper separating area 2, and a return area 3.

[0025] The paper guiding area 1 includes a first paper guiding belt wheel 511 and a second paper guiding belt wheel 512 supporting the paper guiding belt 5, two conical pulleys 11 are arranged between the first paper guiding belt wheel 511 and the second paper guiding belt wheel 512, the conical pulleys 11 separate the two layers of the paper guiding belt by X degrees, so that the pulp board enters the two layers of the paper guiding belt 5; a compression wheel 12 is arranged downstream of the conical pulleys 11 to compress the two layers of the paper guiding belt again.

[0026] The running area is between the second paper guiding belt wheel 51 and the paper winding cylinder 22, and includes a first paper guiding roller 41, a second paper guiding roller 42, and a third paper guiding roller 43; the paper guiding rollers support and drive the pulp board to move in the running area 3, and the pulp board drives the paper guiding belt 5 to move.

[0027] The paper separating area 2 is between the paper winding cylinder 22 and the third paper guiding belt wheel 53; a movable paper winding shaft 21 is arranged on one side of the paper winding cylinder 22; two flat pulleys 23 are arranged below the paper winding cylinder 22 and the paper winding shaft 21, so that the paper guiding belt is separated by Y degrees, Y is greater than X, so that the pulp board can be separated from the side of the separated paper guiding belt under the action of the paper winding shaft 21 and wound on the paper winding shaft 21; a third paper guiding belt wheel 513 is arranged below the paper separating area, and a fourth paper guiding belt wheel 514 is arranged between the third paper guiding belt wheel 513 and the fourth paper guiding belt wheel 514, so that the paper guiding belt returns to the paper guiding area 1 to guide the paper after passing through the return area 3.

[0028] The paper guiding belt 5 has a double-layered folded structure, and the pulp board can be clamped in the middle to make the pulp board move stably. Because the pulp board is heavy, the pulp board cannot be guided by paper blowing after being taken out of the drying part, and can only be manually put into the paper guiding area; the pulp board is clamped between the two layers of the paper guiding belt 5 and starts to be transported. The pulp board runs to the paper separating area under the action of the paper guiding belt and the paper guiding roller, is separated from the two layers of the paper guiding belt in the paper separating area, and is then wound; the paper guiding belt continues to run forward, returns to the paper guiding area again after passing through the return area, guides the paper, and then repeats the above process.

[0029] The paper leading area includes two taper pulleys, each of which contacts one half of the inner side of the folded paper leading belt, and the two taper pulleys intersect to form an acute angle, so that the two layers of paper leading belts are also separated to form an acute angle, and the pulp board enters between the two layers of paper leading belts, and after passing through the compression wheel, the two layers of paper leading belts are combined again to clamp the pulp board. The width of the paper leading belt is smaller than the width of the pulp board, and the two layers of paper leading belts only clamp a part of the pulp board, and the pulp board is driven forward by the friction force of this part. In the paper separating area, only the clamped part is pulled out to perform winding.

[0030] In the paper separating area, the pulp board is wound by the winding shaft, and the paper leading belt continues to move forward through the return area, and then returns to the paper leading area to lead the paper again.

[0031] In the running area 4, the first paper guide roller 41, the second paper guide roller 42 and the third paper guide roller 43 are all wide and contact the pulp board, but do not contact the paper leading belt 5. The paper leading belt 5 is driven to move together with the pulp board by the friction force between the pulp board and the paper leading belt 5. In the paper separating area 2, the winding drum also only contacts the pulp board, but does not contact the paper leading belt 5. The reason is that the part contacting the winding drum needs to be forced, and the paper leading belt does not contact the winding drum. When running in the paper separating area, it only receives the friction force of the pulp board and will not receive the pressure from the winding drum, which is beneficial to the opening of the paper leading belt 5 and facilitates the pulp board to be pulled out. After the winding shaft drives the pulp board to be pulled out from the opened paper leading belt, the pulp board is wound, and the pulp board on the winding shaft will be thicker and thicker, so the winding shaft moves while winding, leaving a gap between the winding shaft and the winding drum for the pulp board to pass through.

[0032] Since the pulp board needs more space to be pulled out than to be introduced, Y needs to be greater than X. When pulling out, the two flat pulleys 23 are preferably perpendicular to open the paper leading belt 5 at 90°, and each flat pulley contacts one half of the inner side of the folded paper leading belt. When leading the paper, the two taper pulleys are preferably opened at 60°.

[0033] The winding and packaging device for pulp boards, the return area 3 is provided with a tensioning device 31 for tensioning the paper leading belt 5.

[0034] The winding and packaging device for pulp boards, the tensioning device 31 includes a pneumatic cylinder 33, and the output end of the pneumatic cylinder 33 is provided with a first moving pulley 311 and a second moving pulley 312. A fixed pulley 313 that does not move with the pneumatic cylinder is arranged between the first moving pulley 311 and the second moving pulley 312, and the paper leading belt 5 passes through the first moving pulley 311, the fixed pulley 313 and the second moving pulley 312 in sequence.

[0035] After the pulp board winding and packaging device is used for a long time, the paper leading belt 5 may not be tightly attached to each pulley, which affects the transportation of the pulp board. Therefore, the tensioning device is arranged to tension the paper leading belt, so that the paper leading belt is tightly attached to each pulley. The pneumatic cylinder 33 is retracted, and the distance between the first moving pulley and the fixed pulley, and the distance between the second moving pulley and the fixed pulley are increased, that is, the tensioning of the paper leading belt is completed.

[0036] The horizontal avoiding device 32 is arranged before and after the tensioning device 31, and the horizontal avoiding device is used to change the running route of the paper strip and to avoid the equipment under the paper roll cylinder.

[0037] The horizontal avoiding device is a distance adjusting wheel set, and the distance adjusting wheel set comprises two parallel distance adjusting pulleys 321, and the distance between the two distance adjusting pulleys 321 in the horizontal direction is set according to the size of the equipment under the paper roll cylinder.

[0038] The two distance adjusting pulleys 321 are provided with a steering pulley 322 perpendicular to the distance adjusting pulley 321, the paper strip 5 is twisted by 90° and parallel to the steering pulley 322 after entering the distance adjusting wheel set from the distance adjusting pulley 321, the paper strip 5 is driven by the steering pulley 322 to move in an oblique upward or oblique downward direction, is twisted by 90° back to the original direction after passing through the two steering pulleys 322, and then leaves the distance adjusting wheel set through the distance adjusting pulley 321 at the other end.

[0039] The two distance adjusting pulleys 321 are arranged in parallel, and the horizontal distance between the two distance adjusting pulleys is set according to the required adjusting distance in the horizontal direction, and the change distance of the running route of the paper strip 5 in the horizontal direction is the horizontal distance between the two distance adjusting pulleys.

[0040] As shown in Figures 6-8 The paper strip 5 passes through the lower distance adjusting pulley 321 and enters the distance adjusting wheel set, is twisted by 90°, passes through the lower steering pulley 322, then passes through the upper steering pulley 322, is twisted by 90° in the opposite direction, i.e., is twisted back to the original running direction, and then leaves the distance adjusting wheel set through the upper distance adjusting pulley 321.

[0041] The working process of the present application is as follows:

[0042] After the pulp board is discharged from the drying part, the pulp board is manually clamped in the nip composed of two taper pulleys and a paper guide belt by an operator, the paper guide belt 5 drives the pulp board to move forward, and the pulp board is clamped into the paper guide belt 5 while moving with the paper guide belt 5. The paper guide belt 5 is re-laminated under the action of the press wheel 12, clamps the pulp board, and drives the pulp board to move. The width of the paper guide belt 5 is smaller than the width of the pulp board, and only a part of the pulp board is clamped, which facilitates subsequent extraction of the pulp board.

[0043] After entering the running area 4, the pulp board enters the paper separating area 2 under the action of the paper guide belt 5 and the paper guide roller, and passes between the paper winding cylinder 22 and the paper winding shaft 21 of the paper separating area 2; when passing through the paper winding cylinder 22, the paper winding shaft 21 extracts the pulp board from between the paper guide belts, and winds the pulp board onto the paper winding shaft 21; two mutually perpendicular flat pulleys 23 are arranged below the paper winding cylinder 22, each flat pulley 23 contacts one side of the inner side of the folded paper guide belt 5, and the two flat pulleys 23 separate the paper guide belt by 90 degrees, facilitating extraction of the pulp board from between the two layers of paper guide belts 5. After the pulp board is extracted, the paper guide belt 5 enters the return area 3, and then re-enters the paper guide area 1, and the paper guide belt 5 is transported, separated, and repeated.

[0044] Due to the large number of auxiliary equipment at the bottom of the paper winding cylinder 22, a distance adjusting pulley set can be further added to deviate the paper guide belt 5 from the original running position, so as to avoid interference with the auxiliary equipment. The uppermost and lowermost two distance adjusting pulleys 321 are arranged in parallel, and the horizontal distance between the upper and lower distance adjusting pulleys is set according to the required adjusting distance in the horizontal direction, and the change distance of the transportation route of the paper guide belt 5 in the horizontal direction is the horizontal distance between the upper and lower distance adjusting pulleys. The paper guide belt 5 runs in the horizontal direction on the distance adjusting pulley, and after the paper guide belt 5 enters the distance adjusting pulley set from the distance adjusting pulley 321, the paper guide belt 5 is twisted by 90 degrees, at this time, the direction of the paper guide belt 5 is parallel to the direction of the deflection pulley 322, and then the paper guide belt 5 moves along the deflection pulley 322 to the upper oblique or lower oblique direction, after passing through the two deflection pulleys, the paper guide belt 5 is twisted by 90 degrees and twisted back to the original running direction, and then the paper guide belt 5 leaves the distance adjusting pulley set from the distance adjusting pulley 321 on the other end, that is, the change of the transportation route of the paper guide belt is completed. The distance adjusting pulley set is arranged in front of the tensioner to avoid the auxiliary equipment below the paper winding cylinder, and the distance adjusting pulley set is arranged behind the tensioner to make the paper guide belt return to the original route.

[0045] The whole paper guide belt 5 is a closed loop structure and circulates under the drive of the paper winding cylinder; the pulp board is continuously introduced into the two layers of paper guide belts from the paper guide area, and then is extracted and wound by the paper winding shaft in the paper separating area, so as to complete the winding of the pulp board.

[0046] Compared with the prior art, the pulp board is cut and packed in the prior art, and the pulp board needs to be cut and then packed, so that the process is complex. The pulp board is clamped and transported by the folded paper guide belt in the present application, and then is extracted and wound by the paper winding shaft, so that the process is simple, the pulp board is wound and packed, and the labor intensity of the operator is reduced.

[0047] The above merely describes the preferred embodiments of the present application, and it should be pointed out that, for those skilled in the art, several changes and improvements can be made without departing from the overall concept of the present application, and these should also be considered as the protection scope of the present application.
