Description

Technical Field

[0001] This invention relates to the field of scrap recycling technology, and in particular to an automatic crushing and recycling device for packaging film scraps. Background Technology

[0002] Packaging film scraps refer to waste or excess parts generated during the production, cutting, bag making, or printing of packaging films. These scraps are usually irregular in shape and small in size, and cannot be used directly for their original purpose. However, because their material still has recycling value, the recycled waste can be processed in various ways. For example, the scraps can be crushed into flakes, washed and dehydrated to make recycled particle raw materials, or melted and granulated by an extruder to make recycled plastic granules for use in low-end products, etc.

[0003] In the pre-processing of packaging film scraps, since the scraps are mostly long strips, they usually need to be cut to shorten them. However, the packaging film material itself is soft and easily accumulates and wraps around the blades during the cutting process. This wrapping not only significantly increases the operating load on the blades, but also, due to the lack of an automatic cleaning mechanism, the tangled material accumulates more and more, leading to equipment overload and shutdown, severely reducing cutting efficiency, resulting in uneven particle size in subsequent crushing, affecting the recycling quality of the scraps, reducing the stability of the production line, and reducing overall processing efficiency; for example, in the existing patent CN2 In patent application 14725602U, a device for crushing and recycling scraps of liquid food packaging film is disclosed. This device addresses the problem that existing methods for handling scraps of liquid food packaging film often involve collecting and incinerating or crushing them for recycling. Incineration not only pollutes the environment and reduces environmental friendliness but also wastes raw materials. Because the scraps of packaging film are lightweight and soft, the crushing quality is not high, and some scraps that are not completely crushed are also discharged, causing inconvenience in subsequent processing. This solution can achieve the effect of crushing and discharging the scraps, but it still cannot achieve the problem of automatic cleaning of the packaging film by the blade.

[0004] Therefore, how to provide an automatic crushing and recycling device for packaging film scraps is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] One objective of this invention is to provide an automatic crushing and recycling device for packaging film scraps. This device includes a crusher with a recycling cylinder. A rotating assembly is located inside the recycling cylinder. A driving assembly is mounted on the rotating assembly. An adjusting assembly is mounted on the rotating assembly. A connecting assembly is mounted on the adjusting assembly. A cutting assembly is mounted on the connecting assembly. A pushing assembly connected to the connecting assembly is mounted on the rotating assembly. A pulling assembly connected to the pushing assembly is mounted on the adjusting assembly. A squeezing assembly connected to the pushing assembly is mounted on the rotating assembly. A contact assembly is located between the rotating assembly and the squeezing assembly. During cutting, the adjusting assembly adjusts the cutting assembly to a suitable position via the connecting assembly. The rotating assembly rotates, driving the cutting assembly to rotate, thus achieving the cutting function. Simultaneously, the contact assembly makes intermittent contact, and the pushing assembly forces the connecting assembly to reciprocate, causing the cutting assembly to move back and forth to cut the scraps.

[0006] Preferably, the rotating assembly includes a support frame disposed inside the recycling cylinder, a rotating rod connected to the support frame by a bearing, a material dispensing rod disposed on the rotating rod, and a mounting plate disposed on the rotating rod.

[0007] Preferably, the drive assembly includes a drive motor mounted on the support frame, the output shaft of the drive motor is connected to a drive bevel gear, and a driven bevel gear that meshes with the drive bevel gear is fixedly sleeved on the rotating rod.

[0008] Preferably, the adjustment assembly includes an electric push rod disposed on the rotating rod, and an adjustment plate is disposed at the output end of the electric push rod, the adjustment plate being sleeved on the outer ring of the rotating rod.

[0009] Preferably, the connecting assembly includes a mounting block disposed on the adjusting plate, a connecting rod hinged to the mounting block, a mounting rod hinged to the connecting rod, an L-shaped rod hinged to the mounting rod, and the L-shaped rod hinged to the mounting block.

[0010] Preferably, the cutting assembly includes a first cutting blade disposed on the mounting rod, the first cutting blade cutting off scrap material vertically, and a second cutting blade adapted to the first cutting blade mounted on the side of the mounting rod, the second cutting blade cutting off scrap material horizontally.

[0011] Preferably, the pushing assembly includes a pushing cylinder hinged to the mounting plate, a pushing piston is disposed inside the pushing cylinder, a pushing rod is disposed on the pushing piston and passing through the pushing cylinder, a pushing block is disposed on the pushing rod, the pushing block is hinged to the L-shaped rod, and a pushing spring is disposed between the pushing cylinder and the pushing block and sleeved on the outer ring of the pushing rod.

[0012] Preferably, the pulling assembly includes a pulling outer rod hinged to the adjusting plate, a pulling inner rod inserted into the pulling outer rod, a baffle provided on the pulling inner rod, the baffle hinged to the pushing cylinder, and a pulling spring sleeved on the outer ring of the pulling inner rod between the pulling outer rod and the baffle.

[0013] Preferably, the extrusion assembly includes an extrusion cylinder disposed on the mounting plate, an extrusion piston disposed inside the extrusion cylinder, an extrusion rod disposed on the extrusion piston and passing through the extrusion cylinder, an extrusion block disposed on the extrusion rod, an extrusion spring disposed between the extrusion cylinder and the extrusion block and sleeved on the outer ring of the extrusion rod, and the extrusion cylinder and the push cylinder are connected through a conduit.

[0014] Preferably, the contact assembly includes a support cylinder disposed on the support frame, a wedge-shaped abutment block disposed on the support cylinder, and a wedge-shaped contact block adapted to the wedge-shaped abutment block disposed on the compression block.

[0015] The beneficial effects of this invention are as follows: In use, the packaging film scraps are placed in a recycling bin. The drive assembly is activated, causing the rotating assembly to rotate and divide the scraps into sections, reducing accumulation. The rotating assembly also drives the adjusting, connecting, and cutting assemblies to rotate. The cutting assemblies contact the scraps, cutting them in multiple directions before they fall into a shredder for further shredding. Because packaging film scraps easily accumulate and become entangled on the cutting assemblies, causing equipment overload, automatic cleaning of the cutting assemblies is necessary. During rotation, the rotating assembly intermittently contacts the contact assembly, causing it to compress and squeeze the component. This forces the gas inside the squeezing and pushing components to switch, causing the pushing component to actuate. This, in turn, causes the connecting component to move intermittently. The connecting component reciprocates around the hinge point, forcing the cutting component to automatically pull back and forth. When the scraps contact the cutting component, the reciprocating cutting component frictionally cuts the packaging film scraps. To prevent the accumulation of scrap materials, the angle of the cutting component is adjusted to meet the needs of cutting scrap materials of different lengths. During adjustment, the adjusting component is activated, and under the action of the pulling and pushing components, the adjusting component drives the connecting component to move around the hinge point, allowing the connecting component to adjust the cutting component to a reasonable angle. For example, when the scrap material falls, the tilted state of the cutting component, combined with the automatic pull-out function, makes it easier to cut the scrap material, further improving the cutting effect and preventing the accumulation of scrap materials. In summary, this application's automatic crushing and recycling device for packaging film scrap materials has a multi-dimensional automatic cleaning effect, preventing scrap materials from accumulating on the cutting component from multiple aspects. It forces the cutting component to produce intermittent pull-out actions, effectively and promptly cutting the accumulated scrap materials, preventing the scrap material entanglement from accumulating more and more, and adjusting the angle of the cutting component to further improve the cutting capacity, prevent scrap material entanglement, avoid equipment overload shutdown, improve cutting efficiency, improve the recycling quality of scrap materials, improve the stability of the production line, and improve overall processing efficiency.

Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0019] Example 1: As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, an automatic crushing and recycling device for packaging film scraps according to the present invention includes a crusher 1, which is a prior art device with a crushing function. A recycling cylinder 2 is provided on the crusher 1 for feeding scraps. A rotating assembly 3 is provided inside the recycling cylinder 2, transmitting rotational force. A drive assembly 4 is provided on the rotating assembly 3, serving as a drive source. An adjusting assembly 5 is provided on the rotating assembly 3, capable of vertical adjustment. A connecting assembly 6 is provided on the adjusting assembly 5, capable of changing shape. A cutting assembly 7 is provided on the connecting assembly 6 for cutting the scraps. A pushing assembly 8 connected to the connecting assembly 6 is provided on the rotating assembly 3. The push assembly 8 drives the connecting assembly 6 to move. The adjusting assembly 5 is equipped with a pulling assembly 9 connected to the pushing assembly 8. The pulling assembly 9 has a pulling effect and improves stability. The rotating assembly 3 is equipped with a squeezing assembly 10 connected to the pushing assembly 8. The squeezing assembly 10 can compress gas. A contact assembly 11 is provided between the rotating assembly 3 and the squeezing assembly 10, and the contact assembly 11 provides intermittent contact. During cutting, the adjusting assembly 5 adjusts the cutting assembly 7 to a reasonable position through the connecting assembly 6. The rotating assembly 3 rotates, driving the cutting assembly 7 to rotate, thereby realizing the cutting function. At the same time, the contact assembly 11 makes intermittent contact, and the pushing assembly 8 forces the connecting assembly 6 to reciprocate, so that the cutting assembly 7 moves back and forth to cut off the scrap.

[0020] Working principle: During use, packaging film scraps are placed in the recycling bin 2. The drive assembly 4 is activated, causing the rotating assembly 3 to rotate. This allows the rotating assembly 3 to divide the scraps into sections for feeding, reducing the accumulation and falling of scraps. The rotating assembly 3 also drives the adjusting assembly 5, connecting assembly 6, and cutting assembly 7 to rotate. The cutting assembly 7 contacts the scraps, cutting them in multiple directions before they fall into the shredder 1 for further shredding. Because packaging film scraps easily accumulate and become entangled on the cutting assembly 7... This causes equipment overload, requiring automatic cleaning of the cutting assembly 7. During rotation, the rotating assembly 3 drives the contact assembly 11 to intermittently contact, causing the contact assembly 11 to compress and squeeze the extrusion assembly 10 back and forth. This forces the extrusion assembly 10 and the gas inside the pushing assembly 8 to switch, causing the pushing assembly 8 to actuate. This in turn causes the pushing assembly 8 to drive the connecting assembly 6 to move intermittently. The connecting assembly 6 reciprocates around the hinge point, forcing the cutting assembly 7 to automatically pull back and forth. When scrap material comes into contact with the cutting assembly 7, the back-and-forth pulling of the cutting assembly 7 is forced to... Friction cutting is used to cut the scraps of packaging film to prevent their accumulation. To accommodate scraps of varying lengths, the angle of the cutting component 7 is adjusted. During adjustment, the adjusting component 5 is activated. Under the action of the pulling component 9 and pushing component 8, the adjusting component 5 drives the connecting component 6 to move around the hinge point. This allows the connecting component 6 to adjust the cutting component 7 to a suitable angle. For example, when the scrap falls, the tilted state of the cutting component 7, combined with the automatic pull-out function, makes it easier to cut the scrap, further improving cutting efficiency. As a result, it avoids the accumulation of scrap materials; in summary, the automatic crushing and recycling device for packaging film scrap materials of this application has a multi-dimensional automatic cleaning effect, which can prevent scrap materials from accumulating on the cutting component 7 from multiple aspects, forcing the cutting component 7 to produce intermittent pulling action, effectively and timely cutting the accumulated scrap materials, preventing the scrap materials from tangling more and more, and can adjust the angle of the cutting component 7 to further improve the cutting ability, prevent scrap materials from tangling, avoid causing equipment overload shutdown, improve cutting efficiency, improve the recycling quality of scrap materials, improve the stability of the production line, and improve the overall processing efficiency.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, an automatic crushing and recycling device for packaging film scraps according to the present invention includes a pushing assembly 8 comprising a pushing cylinder 801 hinged to a mounting plate 304, a pushing piston 802 disposed inside the pushing cylinder 801, the pushing piston 802 being adapted to the pushing cylinder 801, a pushing rod 803 disposed on the pushing piston 802 and passing through the pushing cylinder 801, the pushing rod 803 being disposed along the length direction of the pushing cylinder 801, a pushing block 804 disposed on the pushing rod 803, the pushing block 804 being hinged to an L-shaped rod 604, and a pushing spring 805 sleeved on the outer ring of the pushing rod 803 being disposed between the pushing cylinder 801 and the pushing block 804.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, an automatic crushing and recycling device for packaging film scraps according to the present invention includes a compression assembly 10 comprising a compression cylinder 1001 mounted on a mounting plate 304, a compression piston 1002 disposed inside the compression cylinder 1001, the compression piston 1002 being adapted to the compression cylinder 1001, a compression rod 1003 being disposed on the compression piston 1002 and penetrating the compression cylinder 1001, the compression rod 1003 being disposed along the length direction of the compression cylinder 1001, a compression block 1004 being disposed on the compression rod 1003, a compression spring 1005 being disposed between the compression cylinder 1001 and the compression block 1004 and sleeved on the outer ring of the compression rod 1003, and the compression cylinder 1001 being connected to a push cylinder 801 via a conduit.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, an automatic crushing and recycling device for packaging film scraps according to the present invention includes a contact component 11 comprising a support cylinder 1101 disposed on a support frame 301. The support cylinder 1101 is sleeved on the outer ring of the rotating rod 302 but does not contact the rotating rod 302. A wedge-shaped abutment block 1102 is disposed on the support cylinder 1101. A wedge-shaped contact block 1103 adapted to the wedge-shaped abutment block 1102 is disposed on the extrusion block 1004. Both the wedge-shaped abutment block 1102 and the wedge-shaped contact block 1103 have inclined surfaces.

[0030] Working principle: In use, the packaging film scraps are placed in the recycling bin 2. The drive motor 401 is started, and the output shaft of the drive motor 401 rotates, driving the active bevel gear 402 to rotate. The active bevel gear 402 rotates, driving the driven bevel gear 403 to rotate. The driven bevel gear 403 rotates, driving the rotating rod 302 to rotate. The rotating rod 302 drives the material distribution rod 303 and the mounting plate 304 to rotate. The material distribution rod 303 divides the falling scraps into sections, reducing the accumulation of scraps. The rotation of the mounting plate 304 drives the adjustment component. 5. The mounting block 601, connecting rod 602, mounting rod 603, L-shaped rod 604, pulling component 9 and pushing component 8 rotate. The mounting rod 603 drives the first cutting blade 701 and the second cutting blade 702 to rotate, forcing the first cutting blade 701 and the second cutting blade 702 to cut the falling scrap. The first cutting blade 701 and the second cutting blade 702 cut the packaging film scrap in multiple directions. Then the cut scrap falls into the crusher 1, where the crusher 1 further crushes the scrap, completing the basic cutting function. Because packaging film scraps easily accumulate and become entangled on cutting blades 701 and 702, causing equipment overload, automatic cleaning of cutting blades 701 and 702 is required. During the rotation of the rotating rod 302 and the mounting plate 304, the mounting plate 304 drives the extrusion block 1004 and the wedge-shaped contact block 1103 to rotate, while the support cylinder 1101, mounted on the support frame 301, remains stationary. Therefore, when the wedge-shaped contact block 1103 rotates and contacts the wedge-shaped abutment block 1102, the wedge-shaped abutment block 1102 exerts a squeezing effect on the wedge-shaped contact block 1103, causing the wedge-shaped contact block 1103 to move. This forces the wedge-shaped contact block 1103 to drive the extrusion block 1004 to move, which in turn drives the extrusion rod 1003 to move. The extrusion rod 1003 then drives the extrusion piston 1002 to move within the extrusion cylinder 1001, increasing the gas pressure within the extrusion cylinder 1001. The piston retracts into the push cylinder 801, increasing the gas volume and pressure inside. This forces the push piston 802 to move, driving the push rod 803. The push rod 803 then drives the push block 804, which in turn drives the L-shaped rod 604. The L-shaped rod 604 then drives the mounting rod 603 to move around the hinge point, forcing the first cutter 701 and the second cutter 702 to move along with the mounting rod 603. Because the wedge-shaped contact block 1103 and the wedge-shaped abutment block 1102 are in intermittent contact, the first cutter 701 and the second cutter 702 are forced to move intermittently, resulting in an automatic pull-out action. When the scrap material comes into contact with the first cutter 701 and the second cutter 702, the reciprocating cutter 701 and the second cutter 702 cut the packaging film scrap material, preventing the scrap material from accumulating. When cutting scrap materials, to meet the cutting requirements for scrap materials of different lengths, the angles of cutting blade 701 and cutting blade 702 are adjusted appropriately. During adjustment, the electric push rod 501 is activated. The output end of the electric push rod 501 drives the adjusting plate 502 to move, causing a change in the distance between the adjusting plate 502 and the mounting plate 304. This causes the adjusting plate 502 to drive the mounting block 601 to move, pulling the inner rod 902 within the outer rod 901, thus compressing or stretching the spring 904. Furthermore, the push rod 803 moves within the push cylinder 801, driving the push block 804 to move. This causes the L-shaped rod 604 to move the mounting rod 603 and the connecting rod 602 around the hinge point. This allows the mounting rod 603 to adjust the angles of the first cutting blade 701 and the second cutting blade 702. For example, when scrap material falls, the tilted angles of the first cutting blade 701 and the second cutting blade 702, combined with the automatic pull-out function, make it easier to cut the scrap material, further improving the cutting effect and preventing the accumulation of scrap material.

[0031] This solution features multi-dimensional automatic cleaning, preventing scrap from accumulating on the cutting component 7 in multiple ways. On one hand, it forces the cutting component 7 to perform intermittent pulling motions, effectively and promptly cutting off accumulated scrap and preventing the tangled scrap from accumulating more and more. On the other hand, it can adjust the angle of the cutting component 7 to further improve cutting capacity, prevent scrap from tangling, avoid overload shutdown of the equipment, improve cutting efficiency, improve the recycling quality of scrap, improve the stability of the production line, and improve overall processing efficiency.

[0032] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
