Description

Technical Field

[0001] The technical solution relates to the technical field of cutting and slitting machines, and in particular to a paper cutting and winding device. Background Art

[0002] The cutting and winding machine is an automated equipment specially used for efficient processing of materials such as paper (such as kraft paper). It cuts the wide-width base paper into preset sizes through precise slitting and winding functions, and then winds it onto the bobbin synchronously by a constant tension control system, ensuring uniform slitting width and neat and tight winding.

[0003] The cutting machines currently on the market can cut kraft paper into multiple strips, which are then rolled up on a drum through a winder for subsequent use. The current production line has the problem of multiple process separation operations, requiring multiple devices for cutting, striping, and rolling to operate in relays, and ensuring accurate material transfer, which increases transportation and maintenance costs. In addition, the production line's collaborative efficiency is insufficient and process connection is time-consuming, leading to poor production efficiency. Summary of the invention

[0004] In order to improve the problem of poor production efficiency caused by multiple separate operations in paper processing, the present technical solution provides a paper cutting and winding device.

[0005] The purpose of this technical solution is achieved in this way: A paper cutting and winding device is used to cut and divide paper materials into strips and wind the cut paper strips one by one onto a winding drum, comprising: frame; An unwinding mechanism, which is arranged at the front end of the frame, and drives the paper stock roll to rotate, so as to deliver the paper stock to the cutting mechanism; A cutting mechanism is arranged on the frame, the cutting mechanism comprises a first knife roller rotatably connected to the frame, a second knife roller tangentially matched with the first knife roller, and a cutting drive, the cutting drive drives the first knife roller to rotate, so that the first knife roller cooperates with the second knife roller to cut the paper material passing through the two knife rollers into a plurality of paper strips; A first guiding mechanism, which is rotatably arranged on the frame and located at the discharge side of the cutting mechanism, and is used for pressing and delivering the paper strips; A winding device, the winding device comprises a winding frame and a plurality of winding mechanisms arranged along the winding frame, the winding mechanisms each comprising a winding frame arranged on the winding frame and a winding drum rotating on the winding frame, the winding drive member being used to drive the corresponding winding drum to rotate and perform the paper strip winding operation; The second guiding mechanism includes a conductor assembly and a cable assembly. The conductor assembly pulls and distributes each paper strip to each winding drum in a one-to-one correspondence. The cable assembly is used to guide the paper strip to be evenly wound on the winding drum.

[0006] With the above technical solution, when a paper cutting and winding device is in normal use, the unwinding mechanism drives the reel shaft to rotate continuously to convey the paper material to the cutting mechanism. The cutting driving member drives the first cutter roller to rotate relative to the second cutter roller, and the paper material is continuously cut into multiple parallel strips through the gap between the two cutter rollers. The first guiding mechanism conveys the cut strips to the second guiding mechanism through a rotary pressing action. The wire guiding assembly accurately distributes each strip to the corresponding winding cylinder position of the winding device. The wire arranging assembly synchronously moves to guide the strips to be evenly arranged along the axial direction of the winding cylinder. Each winding driving member independently drives the winding cylinder to rotate to complete multi-channel synchronous winding. This device realizes the full-process continuous production from the unwinding of the base paper to the cutting, winding and finishing of the finished product by integrating the processes of cutting, wire dividing and winding, reduces the downtime waiting caused by the transfer of traditional multiple devices, and improves the processing efficiency and automation degree of the paper material.

[0007] Preferably, the unwinding mechanism includes: A reel shaft, inside which a material positioning assembly is provided. The material positioning assembly includes a positioning cylinder and a positioning member movably connected to the output end of the positioning cylinder. The positioning cylinder drives the positioning member to press against the inner wall of the paper reel, so as to realize the coaxial fixation of the reel shaft and the paper reel. A movable frame, which is horizontally movably arranged on the frame. The movable frame is provided with two bearing seats. Both ends of the reel shaft in the axial direction have rotating shafts, and the rotating shafts at both ends can be inserted into the bearing seats on both sides, so as to guide the rotation of the reel shaft. A loading brake, whose output end is connected to the rotating shaft and is used to drive the rotating shaft to rotate.

[0008] With the above technical solution, the reel shaft passes through the through hole of the paper reel. At this time, both ends of the rotating shaft are guided to rotate through the bearings in the bearing seats. The positioning cylinder pushes the positioning member to radially expand to tightly press against the inner wall of the reel shaft, so as to realize the synchronous locking and power transmission of the rotating shaft and the reel shaft. The loading brake drives the rotating shaft to rotate through a transmission component (such as a gear set). The movable frame is in the unwinding station, and the rotating shaft drives the reel shaft to rotate continuously to release the paper material, realizing the rapid disassembly and assembly of the coil and the coaxial precise fixation, avoiding the time-consuming and eccentric swing problems of the traditional disk fastening method, and ensuring the continuous and stable feeding of the unwinding process.

[0009] Preferably, a material transfer mechanism is provided at the top of the frame. The material transfer mechanism includes: A material transfer crane, which slides along the guide rail on the top of the frame; A material transfer sling, which is movably arranged at the output end of the lower part of the material transfer crane. The material transfer crane drives the material transfer sling to move up and down, and is used to obtain and transfer the reel shaft.

[0010] Through the above technical solution, the material transfer crane slides horizontally along the top guide rail of the frame to the loading and unloading station of the reel shaft. The material transfer lifting tool vertically descends under the drive of the crane, grabs the empty reel or new reel to be replaced, then lifts to a safe height and horizontally transfers it to the bearing seat installation position of the movable frame. The lifting tool is precisely lowered so that both ends of the rotating shaft are embedded in the bearing seat to complete the positioning of the reel. Through the coordinated operation of the rail-mounted crane and the lifting tool, the full-automatic grasping, transfer, and precise positioning of large-size coils are realized, replacing the traditional manual handling or forklift-assisted mode, reducing the intensity and time consumption of coil replacement operations, and improving the material flow efficiency and safety.

[0011] Preferably, the frame is provided with a deviation rectifying mechanism, and the deviation rectifying mechanism includes: The first-direction detection piece; The second-direction detection piece, which is symmetrically arranged with the first-direction detection piece on both sides of the frame along the paper material traveling path, so that the two side edges of the paper material pass through the relative detection openings between the first-direction detection piece and the second-direction detection piece; The deviation rectifying driving piece, whose driving end is connected to the movable frame. When the first-direction detection piece or the second-direction detection piece detects that the paper material deviates from the set position, the deviation rectifying driving piece drives the movable frame to move horizontally, so as to change the output path of the paper material by the winding cylinder.

[0012] Through the above technical solution, when the paper material has a lateral offset during traveling, the detection piece on the offset side triggers a signal, and the deviation rectifying driving piece immediately drives the movable frame to slide horizontally along the frame, driving the entire reel shaft to translate slightly to correct the output path of the paper material, so that the paper material returns to the centered position in real time. Through the closed-loop control of the double detection pieces for dynamic monitoring and the deviation rectifying linkage of the movable frame, the on-line automatic deviation rectification during the paper material unwinding process is realized, thereby reducing the problem of the paper material running off before cutting caused by coil eccentricity, tension fluctuation, or mechanical error, ensuring the consistency of the cut strip width and the winding alignment accuracy, and reducing the frequency of manual intervention and material loss.

[0013] Preferably, the frame is provided with a counting mechanism, and the counting mechanism includes: The rubber wheel, which is arranged on the frame. There is a support rod on the frame, and the rubber wheel rotates and abuts against the support rod, so that when the paper material is conveyed through the gap between the rubber wheel and the support rod, the rubber wheel rolls synchronously with the paper material; The counter, which is linked with the rubber wheel to convert the conveying length of the paper material according to the number of rotations of the rubber wheel.

[0014] Through the above technical solution, the support rod abuts against the rubber wheel to provide a support foundation. During the advancement of the paper material, the rubber wheel remains in contact with the paper material by its own weight or an elastic pressing mechanism. The rubber wheel rotates synchronously as it rolls along the surface of the paper material. The counter calculates the real-time conveying length of the paper material by detecting the number of rotations of the rubber wheel and combining its circumference. When the paper material is about to run out, the operator is reminded to replace the new paper material to avoid subsequent disconnection of the paper material and the need to repeat the cumbersome feeding operation, realizing real-time monitoring and accurate measurement of the paper material unwinding.

[0015] Preferably, the first knife roll is provided with a pressing adjustment assembly, and the pressing adjustment assembly includes: A pressing adjustment seat, which is movably arranged on the frame, and the pressing adjustment seat is fixedly connected to the first knife roll; A pressing adjustment rod, which is in threaded cooperation with the pressing adjustment seat. By adjusting the pressing adjustment rod, the first knife roll is driven to move relative to the second knife roll to adjust the gap between the two; The surface of the first knife roll is provided with annular blades arranged at equal intervals along the axial direction, and the surface of the second knife roll is provided with axially equidistant knife grooves corresponding to and fitting with the annular blades one by one.

[0016] Through the above technical solution, the annular blades can all be correspondingly embedded into the corresponding knife grooves of the second knife roll, and the two rolls form a shearing mating surface to ensure the width consistency of the paper strip shearing; rotate the pressing adjustment rod, and drive the pressing adjustment seat to move up and down through screw transmission, and then drive the first knife roll to move horizontally along the frame to accurately adjust the gap size between the first knife roll and the second knife roll. When the paper material passes through the gap, it is continuously and equidistantly cut into paper strips by the annular blades. Through the screw fine adjustment and the knife groove fitting structure, the cutting gap can be quickly adapted to the requirements of different paper material thicknesses or cutting specifications, ensuring the dynamic alignment accuracy between the blade and the knife groove, and reducing the cumbersome operation of traditional overall roll replacement adjustment.

[0017] Preferably, the first guiding mechanism includes: A driving roller, which is rotatably arranged on the frame; An adjusting roller, which is rotatably arranged on the frame and the rotation axis is parallel to that of the driving roller. The frame is also provided with a pressing adjustment part, which is in threaded cooperation with the adjusting roller to move the adjusting roller relative to the driving roller for adjusting the gap for delivering the paper strip; The frame is provided with a synchronization assembly, which is arranged between the first guiding mechanism and the cutting mechanism. The synchronization assembly includes a shaft seat, a synchronization shaft rotatably arranged on the shaft seat and a synchronization gear. The rotation axis of the synchronization shaft is parallel to that of the adjusting roller. The synchronization gear is coaxially fixed to the synchronization shaft. The adjusting roller is correspondingly provided with a gear one meshing with the synchronization gear, the second knife roll is correspondingly provided with a gear two meshing with the synchronization gear, and the first knife roll is coaxially fixed with a gear three, and the gear three meshes with the gear two.

[0018] Through the above technical solution, the feeding driving member drives the driving roller to rotate, driving the roller surface covered with the wear-resistant layer and the adjusting roller to form a feeding gap. The operator drives the adjusting roller to move horizontally by screwing the pressing and adjusting member, adjusting the distance between the adjusting roller and the driving roller to meet the pressing requirements of paper strips with different thicknesses. After the cut paper strips enter the gap between the driving roller and the adjusting roller, they are clamped and evenly pulled to the next process by the opposite rotation of the two rollers. Through the fine adjustment of the thread and the cooperation with the wear-resistant roller surface, the feeding gap can be quickly adapted to paper strips of multiple specifications, ensuring that the loose paper strips after cutting remain flat and non-sliding during the feeding process. At the same time, the wear-resistant layer reduces the wear of the roller surface caused by long-term friction, extends the maintenance cycle, and improves the feeding stability and equipment durability.

[0019] The synchronous shaft is supported by the shaft seats on both sides of the frame. The synchronous gear is synchronously meshed with the first gear at the end of the adjusting roller and the second gear of the second cutting roller. At the same time, the third gear of the first cutting roller is meshed with the second gear. Through the meshing linkage between the gears, the rotational speeds of the first cutting roller, the second cutting roller, the adjusting roller and the synchronous shaft are matched to achieve synchronous rotation to complete operations such as cutting and paper strip guiding, reducing the cumulative error of multi-stage transmission, and realizing the dynamic coordination of tension adjustment and cutting action.

[0020] Preferably, the frame is provided with a plurality of feeding rollers, and all the feeding rollers are rotatably mounted on the frame for guiding the paper material and the paper strips to feed along a set direction. The frame is provided with a grid frame, and the grid frame has a plurality of guide bar grooves arranged in parallel for the paper strips to pass through one by one correspondingly.

[0021] Through the above technical solution, during the process of the paper material and the cut paper strips being conveyed along the set path, multiple feeding rollers are arranged to cooperate and continuously rotate to guide. The multiple cut paper strips pass through the respective guide bar grooves on the grid frame one by one. The guide bar grooves respectively restrict the traveling directions of the corresponding paper strips, preventing adjacent paper strips from being wound around each other or misaligned and offset, realizing the precise separation and directional transmission of the paper strips, reducing common phenomena such as paper strip drifting, overlapping or knotting during free conveyance, and ensuring the uniform arrangement of the paper strips in the subsequent winding process and the quality of the finished product coil.

[0022] Preferably, the wire guiding assembly includes: A row of wheel frames, which are arranged on the top of the winding frame. A plurality of wire arranging wheels are arranged on the row of wheel frames for guiding the paper strips to the wire stabilizer. Wire guiding frames, which are arranged corresponding to the positions of the winding mechanisms one by one. The wire guiding frames are provided with wire guiding wheels for guiding the paper strips to the winding cylinder. A wire stabilizer, which is arranged on the winding frame. The wire stabilizer has a plurality of wire stabilizing guide heads, and each wire stabilizing guide head is arranged corresponding to the wire guiding frame for guiding the paper strips sent out by the wire arranging wheels to the wire guiding wheels.

[0023] Through the above technical solution, the cut paper strips sequentially pass through the wire arranging wheels of the wire arranging wheel frame for preliminary wire separation, and then are transitioned and turned by the wire stabilizing guide head of the wire stabilizer and dispersed to the corresponding wire guide frames. The wire guide wheels on the wire guide frames accurately guide the paper strips to the corresponding winding cylinders, realizing high-precision independent guiding of multiple paper strips from slitting to winding, effectively avoiding the problems of paper strip cross-winding or uneven tension during multi-channel winding, adapting to the process requirements of different coil diameters and wire arranging densities, and improving the winding neatness.

[0024] Preferably, it further includes a wire arranging seat, on which the wire arranging assembly is provided. The wire arranging assembly includes: A wire arranging frame, which is movably arranged on one side of the wire arranging seat close to the winding frame; A sliding rod, which is connected to the wire arranging frame. The winding frame is provided with a roller group, and the sliding rod is horizontally movably mounted on the winding frame through the roller group. The wire guide frame is fixedly installed on the sliding rod; A wire arranging slider, which is movably connected to the wire arranging seat. The wire arranging slider is fixedly connected to the wire arranging frame. The wire arranging slider is threadedly connected to a lead screw, and the lead screw is rotatably arranged relative to the wire arranging seat; A wire arranging driving member, which is installed on the wire arranging seat. The output end of the wire arranging driving member is connected to the lead screw. The wire arranging driving member drives the lead screw to rotate, causing the wire arranging slider to move back and forth, and the wire arranging frame drives the sliding rod to move synchronously, realizing uniform winding of the paper strip on the winding cylinder.

[0025] Through the above technical solution, the wire arranging driving member drives the lead screw to rotate, and through screw transmission, it pushes the wire arranging slider to linearly reciprocate along the wire arranging seat, driving the fixedly connected wire arranging frame and sliding rod to synchronously move horizontally; the sliding rod smoothly slides on the winding frame through the roller group, so that the wire guide frame fixed to the sliding rod drives the paper strip to be evenly reciprocally arranged along the axial direction of the winding cylinder. The paper strip is tightly wound layer by layer without overlapping wires, realizing high-precision horizontal wire arranging, adapting to the process requirements of different coil widths and wire arranging spacings, replacing the inefficient mode of manually adjusting the wire arranging trajectory, improving the winding flatness and interlayer consistency, and ensuring the stability and durability of long-term operation.

[0026] The prominent and beneficial technical effects of this technical solution compared with the prior art are: 1. Through the integrated functions of cutting, wire separation and winding, this technical solution continuously feeds the material through the unwinding mechanism and precisely cuts it into parallel paper strips by the cutter roller. The guiding mechanism and the wire arranging assembly cooperate to realize the directional distribution of multiple paper strips and the uniform arrangement along the axial direction of the winding cylinder, and drive multiple channels of winding synchronously, reducing the downtime of multi-equipment transfer, improving the production efficiency and automation level, and ensuring the slitting and winding accuracy and the consistency of finished products; 2. This technical solution uses the dual detectors of the deviation rectifying mechanism to monitor the deviation of the paper material in real time, trigger the deviation rectifying driving part to laterally fine-tune the position of the reel, and close-loop control the paper material output path to be centered in real time, eliminating the deviation caused by coil eccentricity and tension fluctuation, ensuring the consistency of the cutting strip width and the winding alignment accuracy, and reducing manual intervention and material waste.

Detailed implementation manners

[0029] The following further elaborates on the detailed implementation manners of the technical solution in conjunction with the attached drawings.

[0030] Embodiment: Refer to Figure 1 and Figure 3 , a paper cutting and winding device for cutting and striping the paper material 200 unwound from the paper material reel 100 and winding the cut paper strips 300 one by one onto the coiling cylinder 622, including a frame 1, on which an unwinding mechanism 2 is provided at the front end of the frame 1. The unwinding mechanism 2 includes a reel shaft 21, a movable frame 22 and a loading brake 23. The movable frame 22 is slidably connected to the frame 1 through a pulley and slideway structure, and its sliding direction is set horizontally.

[0031] The winding shaft 21 is rotatably installed on the movable frame 22. The size and shape of the winding shaft 21 match the shaft hole of the paper roll 100. The paper roll 100 is formed by winding the paper material 200 into a cylindrical shape. The material of the paper material 200 is preferably kraft paper. The winding shaft 21 passes through the shaft hole and is fixed thereto. A material positioning assembly 8 is provided inside the winding shaft 21, which includes a material positioning cylinder 81 and a material positioning member 82. The material positioning member 82 is slidably arranged relative to the winding shaft 21, and its sliding direction is perpendicular to the rotation direction of the winding shaft 21. A relief groove for the material positioning member 82 to pass through is correspondingly formed along the outer wall of the winding shaft 21. The output end of the material positioning cylinder 81 is connected to the material positioning member 82 for driving the material positioning member 82 to move outwards. The material positioning member 82 presses against the inner side wall of the paper roll 100, so that the winding shaft 21 and the paper roll 100 are coaxially fixed, restricting the movement of the paper roll 100. When driving the paper roll 100 to rotate, the paper material 200 can be smoothly sent out.

[0032] Specifically, the installation method is that the movable frame 22 is provided with two bearing seats 9, which are bolted to the upper end surface of the movable frame 22. The bearing seats 9 shown in this embodiment all include a seat body and a seat cover. The seat body and the seat cover are bolted to each other. The winding shaft 21 has a rotating shaft 3, which is arranged at both axial ends of the winding shaft 21. The installation positions of the two bearing seats 9 are adapted to the rotating shafts 3 at both ends; a bearing is sleeved on each rotating shaft 3. By opening the seat cover to open the bearing seat 9, the rotating shafts 3 at both ends can be correspondingly inserted into the two seat bodies one by one, and the seat cover is installed. The bearing guides the rotation of the rotating shaft 3 in the bearing seat 9 to reduce the rotational friction.

[0033] The loading brake 23 is installed on the movable frame 22 and is located beside the winding shaft 21. The loading brake 23 can adopt an electromagnetic powder brake, which is used to provide power to the rotating shaft 3. In this embodiment, it is shown that a first transmission gear is coaxially fixed to the end of the rotating shaft 3 close to the loading brake 23, and a second transmission gear is correspondingly fixed to the output end of the loading brake 23. Through the meshing between the first transmission gear and the second transmission gear, the loading brake 23 can drive the rotating shaft 3 to rotate, and then drive the winding shaft 21 to rotate.

[0034] The frame 1 is provided with a material transfer mechanism 10, which is installed at the top of the frame 1. The top of the frame 1 extends towards the position of the unwinding mechanism 2, so that the position of the material transfer mechanism 10 is above the unwinding mechanism 2. The material transfer mechanism 10 includes a material transfer crane 101 and a material transfer sling 102. Two sets of pulley blocks are symmetrically arranged at the upper end of the material transfer crane 101, and it is slidably connected to the frame 1 by rolling in two grooves symmetrically arranged on the frame 1 through the two sets of pulley blocks. The material transfer sling 102 is installed at the output end of the lower end of the material transfer crane 101. In this embodiment, the shown material transfer sling 102 includes two hooks. The material transfer crane 101 drives the material transfer sling 102 to move up and down. When the material transfer sling 102 is driven to descend, the two hooks are correspondingly sleeved on the two end shafts 3. The material transfer crane 101 drives the material transfer sling 102 to rise and reset, pulling the reel shaft 21 to lift upwards, transporting and placing the paper reel 100 on the movable frame 22, reducing manual handling.

[0035] The frame 1 is provided with feeding rollers 16, and a plurality of them are arranged at intervals along the length direction of the frame 1. Each feeding roller 16 is connected to the frame bodies on both sides of the frame 1 at both ends and is rotatably arranged relative to the frame 1. The rotation axes of each feeding roller 16 are parallel to each other. Through the coordinated feeding of multiple rollers, the synchronous cooperation and spatial phase difference arrangement of the feeding roller 16 array, the paper material 200 is stably fed along a preset angle and direction in a coordinated manner.

[0036] See Figure 3 , the frame 1 is provided with a deviation rectifying mechanism 11, which includes a first-direction detection member 111, a second-direction detection member 112 and a deviation rectifying driving member 113. The second-direction detection member 112 and the first-direction detection member 111 are symmetrically arranged on both sides of the frame 1 along the traveling path of the paper material 200, and are both welded and fixed to the frame 1. The detection ports between the two detection members face each other, forming an oblique cross-monitoring area. The deviation rectifying driving member 113 is installed on the frame 1, and its output end is connected to the movable frame 22. The two feeding rollers 16 guide the paper material 200 through the channel between the first-direction detection member 111 and the second-direction detection member 112. At this time, the two side edges of the paper material 200 pass through the detection ports of the two detection members. When the edge offset of the paper material 200 captured by any one of the detection members exceeds the set threshold, the deviation rectifying driving member 113 is controlled by a control system to operate. The deviation rectifying driving member 113 drives the movable frame 22 to move horizontally, and correspondingly performs horizontal displacement compensation, adjusting the paper material 200 output path of the reel shaft 21 to achieve real-time deviation rectification.

[0037] The frame 1 is provided with a counting mechanism 12, which is located on the side of the deviation rectifying mechanism 11 away from the unwinding mechanism 2. The counting mechanism 12 includes rubber wheels 121 and a counter 122. There are two rubber wheels 121, and the rubber wheels 121 are made of rubber wheels with relatively large friction. The rubber wheels 121 are rotatably connected to the cantilever bracket extending from one side of the frame 1, and their rotation axes are perpendicular to the traveling direction of the paper material 200. The frame 1 is provided with a support rod 29, which is located below the rubber wheels 121 and is fixed to both sides of the frame 1 at both ends, and there is a gap smaller than the thickness of the paper material 200 between it and the rubber wheels 121. The paper material 200 is led out through the lower side of the adjacent feeding rollers 16 and passes through this gap. The rubber wheels 121 elastically press against the paper material 200, and the support rod 29 plays a supporting role. The rubber wheels 121 roll synchronously with the conveying of the paper material 200 through the pressing friction.

[0038] The counter 122 is located between the two rubber wheels 121 and is connected to the cantilever bracket. The counter 122 is coaxially and directly connected to the core shaft of the rubber wheel 121. The counter 122 can adopt a high-precision rotary encoder. The counter 122 converts the signal of the rotation of the rubber wheel 121 into the conveying length of the paper material 200. By continuously recording the length of the paper material roll 100 used this time, a reminder is issued when the paper material 200 on the paper material roll 100 is about to be exhausted. The operator cuts the paper material 200, replaces this paper material roll 100, and bonds the paper material 200 on another paper material roll 100 at the cutting place of the paper material 200; this avoids the need to re-layout the paper material 200 and the paper strip 300 due to the exhaustion of the paper material 200 on the paper material roll 100, reducing trouble.

[0039] See Figure 2 and Figure 4 As shown in

[0040] The splitting driving member 43 is installed on the frame 1, and its output end is connected to the first cutter roller 41, driving the first cutter roller 41 to rotate. When the paper material 200 passes through the cutting area between the two cutter rollers, the annular blade 13 continuously cuts the paper material 200 into equal-width strips 300 corresponding to the spacing of the annular blade 13. Alternatively, the second cutter roller 42 is provided with a plurality of circumferential cutting blades arranged at equal intervals along the axial direction, and each circumferential cutting blade is shearingly engaged with each annular blade 13 one by one.

[0041] The first cutter roller 41 is provided with a pressing adjustment assembly 15, which includes a pressing adjustment seat 151 and a pressing adjustment rod 152. The pressing adjustment seat 151 includes two parts. The two pressing adjustment seats 151 are respectively located on the opposite sides of the frame 1 along the rotation axis of the first cutter roller 41, so that the two ends of the first cutter roller 41 are connected to the pressing adjustment seats 151 on both sides. The pressing adjustment seat 151 is slidably connected to the frame 1, and the sliding direction is vertically arranged. Each pressing adjustment seat 151 is threadedly connected with a pressing adjustment rod 152.
