Description

Technical Field

[0001] The utility model relates to the technical field related to material cutting, in particular to a side cutting device for multi-layer composite sheet materials. Background Art

[0002] Multi-layer composite sheet materials are generally made by pasting and stamping multiple single layers or single sheets together, which makes the thickness thicker and the hardness and performance are greatly improved. Multi-layer composite sheet materials are widely used in daily life. For example, in the field of tableware, with the accelerated pace of life, convenient and fast disposable tableware has emerged. Common disposable tableware includes knives, forks, spoons, chopsticks and other tableware. Most of these disposable tableware are obtained by processing and forming multi-layer composite sheet materials (such as multi-layer composite paper sheets).

[0003] When multiple single-layer or single-sheet materials are pasted and punched together, the side edges of the multi-layer composite sheet materials are generally uneven and have burrs, rough edges and other structures. Therefore, it is also necessary to cut the side edges of the multi-layer composite sheet materials to make the width size of the multi-layer composite sheet materials uniform. The existing multi-layer composite sheet materials are generally pasted and stamped by conveyor rollers with a fast conveying speed. The rigid contact during cutting makes it easy to produce burrs, rough edges and other structures when cutting the side edges of the multi-layer composite sheet materials, affecting the product quality of the multi-layer composite sheet materials.

[0004] For example, Chinese patent CN213562968U discloses a paper machine paper tape cutting and exporting mechanism, in which two cutter assemblies are fixedly arranged on a frame, and the paper contacts the fixed cutter during transportation and then cuts the side, and a blower is arranged on one side to collect waste edges. Through the design of this structure, because the cutter is fixed and the paper produces rigid contact during high-speed transportation and cutting, it is easy for burrs, rough edges and other structures to be generated on the side of the cut paper, affecting the output quality of the multi-layer composite sheet. Therefore, the side cutting structure in the prior art has the problem that burrs, rough edges and other structures are easily generated on the side after cutting the multi-layer composite sheet, and the output quality is poor. Utility Model Content

[0005] The utility model aims to solve the problem that after the side cutting structure in the prior art cuts a multi-layer composite sheet, burrs and the like are easily generated on the side and the product quality is poor.

[0006] To solve the above technical problems, the embodiment of the utility model discloses a side cutting device for a multi-layer composite sheet, which is arranged at the output end of a press forming device for the multi-layer composite sheet. The side cutting device includes a bracket, a conveying roller group, a side rotating cutter assembly and a waste collection part.

[0007] The conveying roller group includes an active conveying roller rotatably arranged on a bracket, and a driven conveying roller drivingly connected to the active conveying roller, the active conveying roller and the driven conveying roller are arranged opposite to each other, and a conveying channel for the multi-layer composite sheet to pass through is provided between the two. The side rotating cutter assembly includes two side rotating cutters arranged at intervals along the width direction of the conveying channel, the two side rotating cutters are fixedly arranged on the roller shaft of the active conveying roller or the driven conveying roller, and the two side rotating cutters rotate synchronously with the active conveying roller or the driven conveying roller.

[0008] The waste collecting portion is located below the side rotating cutter, and has a collecting port facing one side of the side rotating cutter, and when viewed along the width direction of the conveying channel, the end edge of the cutting blade of each side rotating cutter close to the waste collecting portion is closer to the waste collecting portion than the conveying channel.

[0009] By adopting the above technical scheme, the side rotating cutter rotates synchronously with the conveying roller, and the composite sheet material can be cut in real time during the conveying process, thereby saving production time. The cutting position is relatively stable, which helps to ensure the cutting accuracy. The position and angle of the cutter can be adjusted to adapt to composite sheets of different widths and thicknesses, and it can be integrated at the output end of the multi-layer composite sheet pressing and forming equipment, reducing the complexity of the equipment and the footprint.

[0010] More importantly, the synchronous rotation of the side rotating cutter and the conveyor roller can achieve flexible cutting, ensuring the continuity and stability of the side cutting of the multi-layer composite sheet. By cutting with the conveyor roller, the impact and vibration during the cutting process are reduced, and the unevenness and deformation of the material can be more flexibly dealt with, thereby improving the consistency of the cutting effect, thereby ensuring the flatness and accuracy of the cutting surface, and the flexible rotation cutting can also reduce the generation of burrs and flash. The waste collection part is located below the side rotating cutter and can quickly and timely collect waste edges.

[0011] Preferably, the two side rotating cutters are arranged on the roller shaft of the driven conveying roller and are respectively located on the two outer sides of the driven conveying roller. The side rotating cutters are circular cutters, and the cutting blades are cutting blades arranged on the outer peripheral edges of the circular cutters. In addition, two feeding rollers are arranged on the roller shaft of the active conveying roller, and the two feeding rollers are respectively located on the two outer sides of the active conveying roller and at positions corresponding to the two circular cutters. An annular cutting avoidance groove is arranged on the outer periphery of each feeding roller, and the cutting blade of each circular cutter partially extends into the corresponding cutting avoidance groove.

[0012] By adopting the above technical solution, the blade of the circular cutter is set at the outer edge, which can make full use of the characteristics of circular motion to achieve continuous and smooth cutting. The blade of the circular cutter can produce a certain elastic deformation during the cutting process, thereby adapting to the unevenness and deformation of the material. The precise cutting and flexible cutting method of the circular cutter can ensure the flatness and accuracy of the cutting surface. And the cutting blade partially extends into the cutting avoidance groove, avoiding direct contact between the blade and the feed roller, thereby reducing the wear and damage of the blade to the feed roller, and can ensure that the contact between the blade and the material during the cutting process is more stable, thereby improving the cutting accuracy. The design of the cutting avoidance groove helps to reduce vibration and deviation during the cutting process, making the cutting line smoother and more consistent.

[0013] Further preferably, two material blocking and separation assemblies are included, each of which is arranged immediately downstream of a corresponding side rotating cutter in the conveying direction of the multi-layer composite sheet and located outside the side rotating cutter away from the conveying roller group, and when viewed along the width direction of the conveying channel, the two ends of a material blocking and separation assembly in the spacing direction of the conveying channel are respectively located on both sides of the end of one side of the cutting blade of the corresponding side rotating cutter close to the waste collection part. A material blocking installation shaft extending along the width direction of the conveying channel is fixedly arranged on the bracket, and the two material blocking and separation assemblies are spaced from each other and can be translated on the material blocking installation shaft, and are respectively located outside the two side rotating cutters.

[0014] By adopting the above technical solution, the material blocking and separation component can ensure the separation of the side waste and the multi-layer composite sheet after cutting, and quickly guide the side waste after cutting to the waste collection part through the material blocking and separation component, avoiding the accumulation and blockage of waste and improving the collection efficiency of side waste.

[0015] More preferably, two push plates are further included; wherein the two push plates are spaced apart from each other and can be translated on the push installation shaft, the push installation shaft extends along the width direction of the conveying channel, and the ends of the two push plates can be rotated to extend between the lower end of the corresponding discharge cavity and the waste collection part. The push plates can quickly and accurately push the side waste into the waste collection part.

[0016] In summary, the utility model discloses a side cutting device for a multi-layer composite sheet material, which conveys the multi-layer composite sheet material through an active conveying roller and a driven conveying roller, and a circular side rotating cutter is arranged on the driven conveying roller. The side rotating cutter cuts the side of the multi-layer composite sheet material as the multi-layer composite sheet material is conveyed, and the side waste after cutting is collected by a material blocking separation component and introduced into a waste collection part for collection with the assistance of a pushing plate. The device integrates cutting, separation, collection and waste discharge, and has good continuity and stability in side cutting, and the flexible cutting reduces the generation of burrs and flash.

[0040] The current catering and takeaway industries consume a huge amount of disposable knives, forks and spoons. Common disposable plastic knives, forks and spoons are widely accepted because of their mature production technology, sufficient raw material sources and low prices. However, these plastic knives, forks and spoons are also difficult to recycle and cannot be naturally degraded, which poses a huge challenge to our environment. Due to the country's green and environmentally friendly development concept, paper knives, forks and spoons will be widely promoted and applied.

[0041] The raw material of the paper knife, fork and spoon is a multi-layer composite paper. The multi-layer composite paper is pasted into a single sheet with a higher thickness. Finally, the side edges of the multi-layer composite sheet need to be cut to make the width size of the multi-layer composite sheet uniform. In the prior art, when cutting the side edges of the multi-layer composite sheet, the side edges are generally cut by setting a fixed blade. The rigid contact during cutting makes it easy to produce burrs, rough edges and the like when cutting the side edges of the multi-layer composite sheet, resulting in poor product quality of the multi-layer composite sheet.

[0042] In order to solve the above technical problems, the utility model provides a side cutting device that can flexibly cut the side edges of multi-layer composite sheets. By arranging a side rotating cutter that rotates with the conveying roller on the conveying channel, the composite sheet can be flexibly cut in real time during the conveying process, ensuring the continuity and stability of the side cutting of the multi-layer composite sheet.

[0043] Next, the specific structure of the side cutting device of the multi-layer composite sheet disclosed in the utility model is explained and described in detail:

[0044] The implementation of this embodiment discloses a side cutting device for a multi-layer composite sheet material, and the side cutting device is arranged at the output end of a press forming device for a multi-layer composite sheet material. Figure 1 The side cutting device includes a bracket 100, a conveying roller set 200, a side rotating cutter assembly and a waste collecting part 400.

[0045] The output end of the multi-layer composite sheet pressing and molding equipment outputs the multi-layer composite sheet that has been pressed and molded, for example, a pressed 4-layer composite sheet, a 6-layer composite sheet, an 8-layer composite sheet, etc. Taking the 6-layer composite sheet as an example, the 6-layer composite sheet is made of 6 single sheets that are bonded and pressed into a composite sheet, and the side edges of the 6-layer composite sheet will have uneven bonding, wrinkles or lace, etc. Therefore, the side cutting device disclosed in this embodiment is arranged at the output end of the pressing and molding equipment, which can not only cut off the waste at the side edge of the multi-layer composite sheet, but also cut the multi-layer composite sheet into materials of specified size and width.

[0046] See also Figure 1 The conveying roller group 200 includes an active conveying roller 210 rotatably arranged on the bracket 100 and a driven conveying roller 220 drivingly connected to the active conveying roller 210. The active conveying roller 210 and the driven conveying roller 220 are arranged opposite to each other, and there is a conveying channel 230 between the two for the multi-layer composite sheet to pass through. In this embodiment, the spacing size of the conveying channel 230 can preferably be adjusted according to the composite sheets of different numbers of layers. The composite sheets of different numbers of layers correspond to conveying channels 230 of different spacing sizes. For example, the spacing size of the conveying channel 230 when conveying and cutting 6 layers of composite sheets is greater than the spacing size of the conveying channel 230 when conveying and cutting 4 layers of composite sheets. Those skilled in the art can design or select according to actual needs, and this embodiment does not make specific limitations on this.

[0047] The side rotating cutter assembly includes two side rotating cutters 300 arranged at intervals along the width direction of the conveying passage 230. The two side rotating cutters 300 are fixedly arranged on the roller shaft 240 of the active conveying roller 210 or the driven conveying roller 220. The two side rotating cutters 300 rotate synchronously with the active conveying roller 210 or the driven conveying roller 220. For example, both the side rotating cutters 300 may be arranged on the roller shaft 240 of the active conveying roller 210, or both the side rotating cutters 300 may be arranged on the roller shaft 240 of the driven conveying roller 220, or one of the two side rotating cutters 300 may be arranged on the roller shaft 240 of the active conveying roller 210 and the other may be arranged on the roller shaft 240 of the driven conveying roller 220. It should also be noted that the width direction of the conveying channel 230 in this embodiment is the same as the width direction of the multi-layer composite sheet. Further, those skilled in the art should understand that the structures of the roller shaft 240 of the active conveying roller 210 and the driven conveying roller 220 in this embodiment are the same. Therefore, in this embodiment, the roller shaft 240 of the active conveying roller 210 and the driven conveying roller 220 are no longer distinguished and marked.

[0048] The side rotating cutter 300 rotates synchronously with the active conveying roller 210 or the driven conveying roller 220, and can cut the composite sheet in real time during the conveying process without the need for additional cutting steps, thereby saving production time. The cutting position is relatively stable, which helps to ensure cutting accuracy. Flexible rotating cutting can also reduce the generation of burrs and flash. The position and angle of the cutter can be adjusted to adapt to composite sheets of different widths and thicknesses, and it can be integrated at the output end of the multi-layer composite sheet pressing and molding equipment, reducing the complexity of the equipment and the floor space occupied.

[0049] The waste collecting portion 400 is located below the side rotating cutter 300, and the waste collecting portion 400 has a collecting port 410 facing one side of the side rotating cutter 300, and when viewed along the width direction of the conveying channel 230, the cutting blade 310 of each side rotating cutter 300 is close to the end edge of one side of the waste collecting portion 400 and is closer to the waste collecting portion 400 than the conveying channel 230.

[0050] Next, the edge of the cutting blade 310 of each side rotating cutter 300 mentioned in this embodiment, which is closer to the waste collecting part 400 than the conveying channel 230, is explained: the waste collecting part 400 is located on one side of the conveying channel 230, and the cutting blade 310 of the side rotating cutter 300 is closer to the waste collecting part 400 than the conveying channel 230, that is, the cutting blade 310 must at least partially pass through the conveying channel 230 to ensure that after the multi-layer composite sheet passes through the conveying channel 230, the side rotating cutter 300 cuts the multi-layer composite sheet as it rotates with the roller 240 and then cuts the side or waste edge of the sheet, or the cutting blade 310 of the side rotating cutter 300 at least partially invades the conveying channel 230 and exceeds the conveying channel 230 to ensure that the cutting blade 310 can cut the multi-layer composite sheet passing through the conveying channel 230.

[0051] Preferably, the two side rotating cutters 300 are both arranged on the roller shaft 240 of the driven conveying roller 220 and are respectively located on the two outer sides of the driven conveying roller 220. The side rotating cutters 300 are circular cutters, and the cutting blades 310 are cutting blades arranged on the outer peripheral edges of the circular cutters. In addition, two feeding rollers 250 are arranged on the roller shaft 240 of the active conveying roller 210. The two feeding rollers 250 are respectively located on the two outer sides of the active conveying roller 210 and at positions corresponding to the two circular cutters. An annular cutting avoidance groove 251 is arranged on the outer periphery of each feeding roller 250, and the cutting blade of each circular cutter partially extends into the corresponding cutting avoidance groove 251. When the circular cutter rotates one circle with the roller shaft 240, the annular cutting avoidance groove 251 will also rotate one circle with the feeding roller 250, and the circular cutter is always located in the cutting avoidance groove 251 during each cutting.

[0052] The blade of the circular cutter is set at the peripheral edge, which can make full use of the characteristics of circular motion to achieve continuous and smooth cutting. The blade of the circular cutter can produce a certain elastic deformation during the cutting process, so as to adapt to the unevenness and deformation of the material. The precise cutting and flexible cutting method of the circular cutter can ensure the flatness and accuracy of the cutting surface, and the cutting blade partially extends into the cutting avoidance groove 251, avoiding direct contact between the blade and the feed roller 250, thereby reducing the wear and damage of the feed roller 250 to the blade, and ensuring that the contact between the blade and the material during the cutting process is more stable, thereby improving the cutting accuracy, and finally reducing the generation of flash and burrs on the multi-layer composite sheet after cutting, making the cutting area smoother. The design of the cutting avoidance groove 251 helps to reduce vibration and deviation during the cutting process, making the cutting line smoother and more consistent.

[0053] More importantly, the side rotating cutter 300 rotates synchronously with the conveying roller to achieve flexible cutting, ensuring the continuity and stability of the side cutting of the multi-layer composite sheet. By cutting with the conveying roller, the impact and vibration during the cutting process are reduced, and the unevenness and deformation of the material can be more flexibly dealt with, thereby ensuring the consistency of the cutting effect, and further ensuring the flatness and accuracy of the cutting surface. The waste collection part 400 is located below the side rotating cutter 300 and can quickly and timely collect waste edges.

[0054] Further preferably, the side cutting device for the multi-layer composite sheet disclosed in this embodiment further includes two blocking and separating assemblies 500, each of which is arranged immediately downstream of a corresponding side rotating cutter 300 in the conveying direction of the multi-layer composite sheet, and is located outside the side rotating cutter 300 away from the conveying roller group 200, and when viewed along the width direction of the conveying channel 230, the two ends of a blocking and separating assemblies 500 in the spacing direction of the conveying channel 230 are respectively located on both sides of the end of one side of the cutting blade 310 of the corresponding side rotating cutter 300 close to the waste collection part 400. A blocking mounting shaft 510 extending in the width direction of the conveying channel 230 is fixedly arranged on the bracket 100, and the two blocking and separating assemblies 500 are spaced from each other and can be translated on the blocking mounting shaft 510, and are respectively located outside the two side rotating cutters 300.

[0055] It should be noted that, in the present embodiment, each material blocking and separating component 500 is arranged immediately downstream of a corresponding side rotating cutter 300 in the conveying direction of the multi-layer composite sheet material, which means that each material blocking and separating component 500 is located downstream of a corresponding side rotating cutter 300 and close to the position of the side rotating cutter 300. For example, each material blocking and separating component 500 is arranged downstream of the side rotating cutter 300 and close to the side rotating cutter 300 at a position of 1 to 5 mm. Each material blocking and separating component 500 is located on the outside of a side rotating cutter 300 away from the conveying roller group 200, which means that after the side of the multi-layer composite sheet transmitted on one side of the conveying roller group 200 is cut, the side waste is located on the outside away from the conveying roller group 200. Therefore, the material blocking and separating component 500 is set on the outside of the side rotating cutter 300 away from the conveying roller group 200 to separate the cut waste and introduce it into the waste collection part 400, thereby realizing the cutting of the side waste, the separation of the side waste and the introduction of the side waste into the waste collection part 400.

[0056] Next, the two ends of a material blocking and separating assembly 500 in the spacing direction of the conveying channel 230 in this embodiment are respectively located on both sides of the end portion of the cutting blade 310 of the corresponding side rotating cutter 300 close to the waste collecting portion 400 are explained: First, as mentioned above, the spacing direction of the conveying channel 230 can be understood as the gap of the conveying channel 230 or the thickness direction of the channel, and then the material blocking and separating assembly 500 is located on one side of the side rotating cutter 300. In order to ensure that the side waste can be separated in time, the material blocking and separating assembly 500 is located on both sides of the end portion of the side close to the cutting blade 310 close to the waste collecting portion 400, that is, the material blocking and separating assembly 500 is located in the partial space between the cutting blade 310 and the waste collecting portion 400 (see Figure 2 ), when the side waste is cut, it is separated and blocked by the material blocking and separating assembly 500, enters the material blocking and separating assembly 500, and is discharged into the waste collecting part 400.

[0057] A material blocking installation shaft 510 extending along the width direction of the conveying channel 230 is fixedly set on the bracket 100. Two material blocking and separating components 500 are spaced apart from each other and can be translated on the material blocking installation shaft 510 and are respectively located on the outside of the two side rotating cutters 300. When the width of the conveyed multi-layer composite sheet material changes, the two material blocking and separating components 500 are adjusted accordingly on the material blocking installation shaft 510. For example, when the width of the conveyed multi-layer composite sheet material changes from 60 cm to 70 cm, the positions of the two side rotating cutters 300 and the two material blocking and separating components 500 are adjusted.

[0058] Through this structural design, the material blocking and separation component 500 can ensure the separation of the side waste and the multi-layer composite sheet after cutting, and quickly guide the side waste after cutting to the waste collection part 400 through the material blocking and separation component 500, avoiding the accumulation and blockage of waste and improving the collection efficiency of side waste.

[0059] The embodiment of the present invention also discloses a side cutting device for a multi-layer composite sheet material. Each material blocking and separating assembly 500 includes a separating plate 520 and a material blocking plate 530. Figure 2 and Figure 3 One end of the separation plate 520 is connected to the material blocking installation shaft 510, extends perpendicularly to the material blocking installation shaft 510 toward the corresponding side rotating cutter 300, and the other end is in contact with the outer wall of the corresponding side rotating cutter 300. The material blocking plate 530 extends from the middle of the separation plate 520 in a direction parallel to the material blocking installation shaft 510 toward a direction away from the side rotating cutter 300. A discharge cavity 540 is formed between the separation plate 520 and the material blocking plate 530, the opening of the discharge cavity 540 faces the outer side of the corresponding side rotating cutter 300, and the lower end of the discharge cavity 540 is connected to the waste material collecting part 400.

[0060] Further preferably, each material blocking separation assembly 500 also includes an adjusting mounting component 550, which includes a connecting portion 551 sleeved on the material blocking mounting shaft 510. Specifically, the connecting portion 551 can be an arc-shaped connecting plate, an arc-shaped mounting plate, a clamp or other structure arranged on the material blocking mounting shaft 510.

[0061] One end of the connecting portion 551 is open and provided with an adjustment handle 552, which passes through one end of the connecting portion 551 to adjust the locking or unlocking of the connecting portion 551 relative to the material stopper mounting shaft 510. One end of the separation plate 520 is connected to the side wall 110 of one end of the connecting portion 551 close to the corresponding side rotating cutter 300, and the other end of the connecting portion 551 away from the side rotating cutter 300 is also provided with an auxiliary material stopper plate 553 extending toward the discharge cavity 540.

[0062] For example, when the connecting portion 551 is set as two arc-shaped connecting plates, the middle parts of the two arc-shaped connecting plates are fitted with the material stopper installation shaft 510, and the adjusting handle 552 passes through one end of the two arc-shaped connecting plates. When the adjusting handle 552 is tightened, the two arc-shaped connecting plates are locked relative to the material stopper installation shaft 510. When the adjusting handle 552 is loosened, the two arc-shaped connecting plates are unlocked relative to the material stopper installation shaft 510 and can be adjusted along the material stopper installation shaft 510. After the adjustment, tighten the adjusting handle 552. The auxiliary material stopper plate 553, the separation plate 520 and the material stopper plate 530 are in an "H" shape, and a discharge cavity 540 is formed near one side of the side rotating cutter 300. When the side waste of the multi-layer composite sheet is cut, it will be separated by the separation plate 520 into the discharge cavity 540, and the lower port of the discharge cavity 540 is connected to the collecting port 410. Then it is discharged into the waste collection part 400 through the lower port of the discharge cavity 540.

[0063] The implementation of this embodiment also discloses a side cutting device for a multi-layer composite sheet material, which also includes two push plates 600; wherein the two push plates 600 are spaced apart from each other and can be translated on a push installation shaft 610, and the push installation shaft 610 extends along the width direction of the conveying channel 230. The push installation shaft 610 is rotatably arranged on the bracket 100 and is transmission-connected to the roller shaft 240 of the active conveying roller 210. In the width direction of the conveying channel 230, the two push plates 600 are respectively aligned with the lower ends of the discharge chambers 540 of the two blocking and separating assemblies 500. In addition, the ends of the two push plates 600 can be rotatably extended into between the lower ends of the corresponding discharge chambers 540 and the waste collection part 400.

[0064] Please note that, see Figure 2 An arc-shaped avoidance groove 560 is also provided at the lower end of the material blocking and separating component 500. The shape of the arc-shaped avoidance groove 560 is adapted to the outermost active trajectory of the push plate 600 during rotation to avoid interference between the material blocking and separating component 500 and the push plate 600. Then, when the push plate 600 rotates one circle along with the push mounting shaft 610, the push plate 600 can rotate through the arc-shaped avoidance groove 560 to extend between the lower end of the discharge cavity 540 and the waste collecting part 400, and then push the side waste into the waste collecting part 400.

[0065] The embodiment of the present invention also discloses a side cutting device for a multi-layer composite sheet, see Figure 1 The support 100 includes two side walls 110 spaced apart in the width direction of the conveying passage 230. The roller shaft 240 of the active conveying roller 210, the roller shaft 240 of the driven conveying roller 220, the material stopper installation shaft 510, and the push installation shaft 610 are mounted on the two side walls 110 in parallel with each other.

[0066] A driving motor 260 is fixedly arranged on the outer side of one side wall 110, and the power output end of the driving motor 260 is connected to one end of the roller shaft 240 of the active conveying roller 210. A transmission gear set is arranged on the outer side of the other side wall 110, and the transmission gear set includes a driving gear 261 arranged at the other end of the roller shaft 240 of the active conveying roller 210, and a driven gear 262 respectively arranged at the corresponding end of the roller shaft 240 of the driven conveying roller 220 protruding from the other side wall 110, and the corresponding end of the push installation shaft 610 protruding from the other side wall 110, and meshing with the driving gear 261 in sequence.

[0071] Finally, the structure of the side edge cutting device of the multi-layer composite sheet disclosed in the utility model and the method of cutting the side edge of the multi-layer sheet are described:

[0072] See also Figure 1 The bracket 100 of the side cutting device includes two support plates arranged at both ends of the conveying roller group 200. The conveying roller group 200 is rotatably arranged on the side wall 110 of the bracket 100. The conveying roller group 200 includes an active conveying roller 210 and a driven conveying roller 220. There is a conveying channel 230 for conveying multi-layer composite sheets between the active conveying roller 210 and the driven conveying roller 220. Two circular side rotating cutters 300 are arranged on the driven conveying roller 220. The side rotating cutters 300 rotate with the driven conveying roller 220 and can flexibly cut the two sides of the multi-layer composite sheet. A material blocking installation shaft 510 is also provided at a downstream position on one side of the driven conveying roller 220, and an adjustable material blocking separation assembly 500 is provided on the material blocking installation shaft 510 through an adjusting handle 552. The separation plate 520 and the material blocking plate 530 in the material blocking separation assembly 500 separate the side waste and separate it into the discharge chamber 540. The lower end of the discharge chamber 540 is connected to the waste collecting part 400, and a pushing installation shaft 610 and a pushing plate 600 are also provided on the downstream side of the material blocking separation assembly 500.
