Description

Technical Field

[0001] The present application relates to the technical field of composite film production, and in particular to a composite film waste cutting structure. Background Art

[0002] Composite film refers to a multi-layered structure formed by combining various plastics with paper, metal, or other materials through lamination, extrusion coating, co-extrusion, and other processes. Composite film production often generates waste. To avoid resource waste and maximize business profitability, this waste is cut, crushed, and then recycled.

[0003] The patent with announcement number CN220129249U discloses "a composite film waste recovery device, including a box body, with a feed hopper fixedly connected to the right side of the upper end of the box body. The utility model adopts the above structure, and the discarded composite film falls into the interior of the box body through the feed hopper. The composite film is first dried by the action of a hot air blower, and then dried again by the action of a heating plate in the guide plate. When the guide plate moves back and forth through a vibration mechanism, the composite film jumps on the guide plate, so as to better contact with the heat in the box body so that the composite film is fully heated, causing it to be stretched and deformed or even softened and degummed. Then, the crushing mechanism can be conveniently used to crush the composite film, avoiding the situation where the blade is stuck due to insufficient crushing directly by the crushing knife, thereby effectively improving the crushing effect of the discarded composite film."

[0004] Regarding the above-mentioned related technologies, the inventor believes that they drive the crushing blades to cut and crush the waste by rotating two shafts, but the composite film waste is generally in the form of long strips. After the crushing blades rotate, they will cut the waste longitudinally, making the waste crushed and falling from the shafts easy to form strips, and the crushing of the waste is not sufficient, so it needs to be improved.

[0024] The following is combined with Figures 1-4 This application is described in further detail.

[0025] The embodiment of the present application discloses a composite film waste cutting structure.

[0026] A composite film waste cutting structure, referring to Figure 1-3 , including a processing box 1, a feed hopper 11 and a cutting mechanism.

[0027] Reference Figure 1-3 The feed hopper 11 is fixed on the top of the inner wall of the processing box 1. The user can feed the composite film waste into the processing box 1 through the feed hopper 11. The internal components of the processing box 1 can cut and crush the waste to reduce the volume of the waste for later recycling.

[0028] Reference Figure 1-3 The cutting mechanism includes a first cutting component and a second cutting component. The first cutting component includes two rotating rollers 2 that are arranged in the processing box 1 and directly below the feed hopper 11, and a plurality of cutting knives 21 that are fixed on the outer walls of the two rollers 2 and staggered. After the two rollers 2 rotate, they will drive the staggered cutting knives 21 to rotate, so that the staggered cutting knives 21 can cut the waste fed from the feed hopper 11 into strips longitudinally.

[0029] Reference Figure 2-4 The second cutting assembly includes a material guide table 3 fixedly arranged in the middle of the inner wall of the processing box 1 and provided with a tapered hole, a fixed knife 31 fixedly arranged at the bottom of the tapered hole of the material guide table 3, a bottom plate 32 rotatably arranged at the bottom of the material guide table 3, and a crushing knife 33 rotatably arranged on the top of the bottom plate 32 and cooperating with the fixed knife 31. The fixed knife 31 is located below the two rollers 2, and the top of the bottom plate 32 cooperates with the bottom of the material guide table 3. The material guide table 3 can guide the material through the tapered hole, so that the waste cut into strips can fall onto the bottom plate 32 under the tapered hole guide. The rotating crushing knife 33 cooperates with the fixed fixed knife 31 to cross-cut and crush the waste on the bottom plate 32 like scissors, so that the waste can be cut and crushed more fully and in a smaller volume.

[0030] Reference Figure 1-3 One end of the two rollers 2 is respectively fixed with a first gear 22 and a second gear 23 located outside the processing box 1, and the first gear 22 and the second gear 23 are meshed and connected. The processing box 1 is provided with a driving assembly for driving the rollers 2 and the crushing knife 33 to rotate. The driving assembly includes a first motor 24 located outside the processing box 1 and a second motor 34 fixed to the bottom of the bottom plate 32. The output end of the first motor 24 is fixed in the first gear 22, and the crushing knife 33 is fixed on the outer wall of the output end of the second motor 34.

[0031] After the first motor 24 is running, it will drive the first gear 22 to rotate. After the first gear 22 rotates, it will drive the meshed second gear 23 to rotate in the opposite direction, thereby driving the two rollers 2 to rotate in the opposite direction. The two rollers 2 rotating in the opposite direction can cut the waste through the cutting knife 21. After the second motor 34 is running, it will drive the crushing knife 33 to rotate. The rotating crushing knife 33 cooperates with the fixed knife 31 to cut and crush the waste again.

[0032] Reference Figure 1 and Figure 3A fixing frame 25 is fixed on the outer wall of the processing box 1 , and the first motor 24 is fixed on the inner side of the fixing frame 25 . The processing box 1 can fix the fixing frame 25 , and the fixing frame 25 can support and fix the first motor 24 .

[0033] Reference Figure 2 An inclined electric push rod 35 is provided for rotation between one end of the bottom plate 32 and the inner wall of the processing box 1. The electric push rod 35 can be an existing multi-stage electric telescopic rod. After the electric push rod 35 is extended and retracted, it will drive the bottom plate 32 to rotate, so that one end of the bottom plate 32 can rotate downward or upward. After rotating upward, the bottom plate 32 will rest against the bottom of the material guide table 3 to receive the material, and after rotating downward, the bottom plate 32 will dump the cut and crushed waste downward.

[0034] Reference Figure 2 A telescopic hose 4 is fixedly provided between the bottom of the end of the bottom plate 32 away from the electric push rod 35 and the inner wall of the processing box 1. An air guide pipe 41 is provided in the telescopic hose 4 for blowing air to the top of the bottom plate 32 when one end of the bottom plate 32 rotates downward. The top of the air guide pipe 41 is fixed in the tapered hole of the material guide table 3. The bottom end of the air guide pipe 41 passes through the bottom plate 32 and extends to the interior of the telescopic hose 4. The telescopic hose 4 is a hose with a telescopic effect such as a bellows. The air guide pipe 41 can connect the air in the processing box 1 with the air in the telescopic hose 4. When one end of the bottom plate 32 rotates downward, the telescopic hose 4 will be compressed, so that the air in the telescopic hose 4 is quickly discharged through the air guide pipe 41 to form wind force, which can accelerate the falling of waste on the bottom plate 32.

[0035] Reference Figure 1-2 A collection box 12 for catching the cut waste is slidingly provided at the bottom of the inner wall of the processing box 1. A handle is fixedly provided on one side of the collection box 12. The collection box 12 can catch the waste dumped from the bottom plate 32. The collection box 12 collects the cut and crushed waste. Later, people can pull the collection box 12 out of the processing box 1 through the handle to take out the waste in the collection box 12 for recycling.

[0036] The implementation principle of the composite film waste cutting structure in the embodiment of the present application is as follows:

[0037] During use, the user can feed the composite film waste into the processing box 1 through the feed hopper 11, and turn on the first motor 24 and the second motor 34. After the first motor 24 is running, it will drive the first gear 22 to rotate. After the first gear 22 rotates, it will drive the meshed second gear 23 to rotate in the opposite direction, thereby driving the two rollers 2 to rotate in the opposite direction. The two rollers 2 rotating in the opposite direction can cut the waste longitudinally through the cutting shears 21. The waste cut into strips can fall onto the bottom plate 32 under the guide of the tapered hole of the guide table 3;

[0038] After the second motor 34 is running, it will drive the crushing blade 33 to rotate. The rotating crushing blade 33 cooperates with the fixed blade 31 to cut and crush the waste on the bottom plate 32 like a pair of scissors, so that the waste can be cut and crushed more fully and in a smaller volume.

[0039] After cutting and crushing, the user can control the electric push rod 35 to extend and retract, thereby driving the bottom plate 32 to rotate. When one end of the bottom plate 32 rotates downward, the waste on the top will be poured downward. The collection box 12 can catch the waste poured from the bottom plate 32, and the collection box 12 will collect the cut and crushed waste in a centralized manner.

[0040] At the same time, when one end of the bottom plate 32 rotates downward, it compresses the telescopic hose 4, so that the air in the telescopic hose 4 is quickly discharged through the air guide pipe 41 to form wind force, which can accelerate the falling of waste on the bottom plate 32 and reduce the residue of waste on the bottom plate 32.

[0041] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
