Description

Technical Field

[0001] This invention relates to the field of packaging equipment, and more specifically to a crushing device and packaging mechanism for packaging. Background Technology

[0002] Waste recycling is an important measure for maintaining environmental sanitation, protecting public health, promoting resource recycling, and achieving sustainable development. Water bottles and beverage bottles are among the main categories of waste, and their recycling is of great significance. Current technologies typically involve steps such as placement, sorting, packaging, storage, and transportation of waste bottles. During packaging, the bottles need to be flattened; otherwise, their large size makes them difficult to package and transport.

[0003] To flatten waste bottles, document CN120095993A discloses a bottle-flattening assembly. This assembly uses a conveyor belt, a driving pressure roller, and a driven pressure roller. Waste bottles are conveyed by the conveyor belt to the space between the driving and driven pressure rollers for flattening. Since the sorted waste bottles are made of plastic and have a certain degree of elasticity, they are highly likely to slip or pop out before entering the space between the driving and driven pressure rollers, preventing them from being flattened and ultimately causing blockages that affect the normal operation of the equipment, especially the bottle caps and necks. The bottle cap is hard and easily slips and pops out when directly inserted into the driving and driven pressure rollers. To address this, the driving and driven pressure rollers are equipped with a first annular groove and a second annular groove to allow the bottle cap to enter the annular groove and prevent slippage. However, this leads to the following problems: 1. It is difficult to align the bottle cap with the annular groove; if misaligned, it is still easy to slip and pop out; 2. The presence of the annular groove prevents the bottle body from being fully compressed. Therefore, this invention proposes a crushing device for packaging, which can prevent slippage and popping out during the flattening process, improve flattening efficiency, and ensure that the bottle body is fully compressed, thus facilitating packaging. Summary of the Invention

[0004] To address the technical problem in existing technologies where waste bottles are difficult to smoothly enter between the pressure rollers, this invention provides a crushing device and packaging mechanism for packaging, thus solving the aforementioned technical problem.

[0005] The technical solution of the present invention is as follows:

[0006] This invention provides a crushing device for packaging, comprising:

[0007] At least one set of pressure rollers, including two pressure rollers that cooperate to apply pressure, namely a first pressure roller and a second pressure roller;

[0008] At least one gripping disc, which cooperates with a first pressure wheel to hook into an object to be pressured, and the gripping disc cooperates with a second pressure wheel to send the object to be pressured between the two pressure wheels for pressure application, the gripping disc having a claw formed thereon, and a region A for receiving the end of the object to be pressured being formed between the claw of the gripping disc and the teeth of the first pressure wheel.

[0009] By setting the packaging crushing device to include at least one set of pressure rollers and at least one gripping disc, when the end of the object to be crushed extends into the area between the gripping disc and the first pressure roller, the teeth of the first pressure roller can press against the end of the object to be crushed towards the gripping disc, so that the claws of the gripping disc can hook the end of the object to be crushed; after the gripping disc hooks the end of the object to be crushed, the object to be crushed is hooked between the gripping disc and the first pressure roller; then, the claws of the gripping disc, hooking the end of the object to be crushed, move towards the second pressure roller to the range of movement of the teeth of the second pressure roller, and the teeth of the second pressure roller cause the end of the object to be crushed to disengage from the claws, and the object to be crushed enters between the two pressure rollers, and the two pressure rollers apply pressure to the object to be crushed and flattened. This application employs a gripping disc with hooks that cooperate with a first pressure wheel. The hooks can hook onto the object being pressured and pull it in. A region A is formed between the hooks of the gripping disc and the teeth of the first pressure wheel to accommodate the end of the object being pressured. This region A limits the end of the object being pressured, allowing it to pass smoothly between the gripping disc and the first pressure wheel, and between the two pressure wheels, thus completing the pressure application. The hooking action of the gripping disc's hooks, combined with the limiting effect of region A on the end of the object being pressured, prevents the object from slipping or popping out.

[0010] According to one embodiment of the present invention, the claws of the gripping disc partially engage with the teeth of the first pressure wheel to apply initial pressure to the object being pressured.

[0011] By setting the claws of the gripping disc to partially mesh with the teeth of the first pressure wheel, the object to be pressed can be initially pressed. The object is preliminarily flattened before entering the two pressure wheels, which facilitates its smooth entry between the two pressure wheels without slipping and also improves the flattening efficiency.

[0012] According to one embodiment of the present invention, the gripping disc includes a plurality of spaced-apart claw discs, the hooks on the claw discs being arranged along the circumference of the claw discs and inclined along their own rotation direction. The gripping disc is configured with a plurality of spaced-apart claw discs, the thickness of which is relatively small. When the local structural hardness of the object being pressed is high in the meshing area between the gripping disc and the first pressure wheel, the claw discs can undergo slight deformation, thus avoiding the problem of rigid meshing easily squeezing out the object being pressed. The hooks on the claw discs facilitate hooking onto and pulling in the object being pressed.

[0013] According to one embodiment of the present invention, a plurality of claw discs are fixed on a claw disc shaft, and adjacent claw discs are detachably connected by spacers. The plurality of claw discs of the gripping disc are connected as a whole by a first fastener. The above configuration enables detachable assembly of the gripping disc.

[0014] According to one embodiment of the present invention, the pressure wheel includes a plurality of gears arranged at intervals. The claw discs of the gripping disc and the gears of the second pressure wheel are alternately offset in the axial direction. The hooks on the claw discs extend into the gaps between the teeth of adjacent gears of the second pressure wheel. The cooperation relationship between the gripping disc and the second pressure wheel allows the gripping disc and the second pressure wheel to be arranged as close as possible, so that the object being pressured between the gripping disc and the first pressure wheel can be as close as possible to the entrance of the pressure area of ​​the two pressure wheels, facilitating entry between the pressure areas of the two pressure wheels.

[0015] According to one embodiment of the present invention, a plurality of gears are fixed on a gear shaft, and a retaining ring is provided between two adjacent gears. The plurality of gears and the retaining ring of the pressure wheel are connected as a whole by a second fastener. The structural design of the pressure wheel facilitates disassembly, assembly, and maintenance.

[0016] According to one embodiment of the present invention, guide plates are mounted on opposite sides of the two pressure rollers, and the guide plates are disposed between adjacent gears of each pressure roller. The guide plates can guide the movement of the object being pressured, and at the same time, can prevent the object being pressured from getting stuck in the gap between adjacent gears and being unable to disengage from the pressure rollers.

[0017] According to one embodiment of the present invention, a plurality of anti-return buckles are fixedly assembled between the gripping disc and the second pressure wheel. Each anti-return buckle is located in the interval between two adjacent gripping discs. The first side of the anti-return buckle near the first pressure wheel includes a rejection section and a blocking section. The rejection section is an outwardly convex arc-shaped edge located between adjacent gripping discs. The blocking section protrudes from the gripping disc. The second side of the anti-return buckle near the second pressure wheel is an arc-shaped edge extending parallel to the tooth tip circle R1 of the second pressure wheel. A gap is left between the second side and the tooth tip circle R1 of the second pressure wheel.

[0018] The anti-return latch is designed to block the object being pressed, preventing it from moving between the gripping disc and the second pressure wheel. The first side of the anti-return latch prevents the object from becoming embedded in the gap between two adjacent gripping discs. An object embedded in the gap can be moved out of the gap by the action of the first side, which also prevents the object from moving away from the two pressure wheels. The second side of the anti-return latch is positioned close to the teeth of the second pressure wheel without interfering with them. The gripping disc's claws, the teeth of the second pressure wheel, and the anti-return latch work together to almost completely block the object being pressed, preventing it from moving between the gripping disc and the second pressure wheel.

[0019] According to one embodiment of the present invention, the first side and the second side intersect to form a first intersection point P1, and the stroke circle R2 of the gripping disk's claw and the tooth tip circle R1 of the second pressure wheel intersect to form two intersection points, wherein the intersection point closer to the first pressure wheel is the second intersection point P2. The first intersection point P1 protrudes from the stroke circle R2 of the gripping disk's claw, and the first intersection point P1 is located close to the second intersection point P2.

[0020] By setting the first intersection point P1 of the anti-reverse latch to protrude from the stroke circle R2 of the gripper's claw, the anti-reverse latch can block the object being gripped by the claw, thus restricting the direction of movement of the object. If the first intersection point P1 is further set close to the second intersection point P2, then when the object being gripped is blocked by the anti-reverse latch, the end of the object can be partially located within the tooth tip circle R1 of the second pressure wheel. The teeth of the second pressure wheel can then act on the end of the object, bringing it to the pressure area between the two pressure wheels for pressure application.

[0021] According to one embodiment of the present invention, the teeth of the pressure rollers have an involute profile, and the teeth of the two pressure rollers mesh with each other. By setting the teeth of the pressure rollers to have an involute profile and the teeth of the two pressure rollers meshing with each other, the object to be pressed can be flattened.

[0022] The present invention also provides a packaging mechanism, including: a crushing device for packaging.

[0023] Based on the above technical solution, the technical effects that the present invention can achieve are as follows:

[0024] 1. The packaging crushing device of the present invention, when crushing an object, firstly hooks and limits the end of the object by cooperating with a gripping disc and a first pressure roller, hooking the object into and passing it between the gripping disc and the first pressure roller, thus applying initial pressure to the object; after passing between the gripping disc and the first pressure roller, the end of the object is blocked by a check buckle, and the end of the object is located between the gripping disc and the two pressure rollers, and partially within the tooth tip circle R1 of the second pressure roller. The teeth of the second pressure roller cause the end of the object to detach from the hook of the gripping disc and enter the entrance of the pressure area of ​​the two pressure rollers. The two pressure rollers cooperate to apply pressure to the object, and after being pressed, the object detaches from the pressure rollers under the action of a guide plate and leaves the pressure area. The packaging crushing device, by first hooking the object into the space between the gripping disc and the first pressure roller for initial pressure, and then applying pressure through the two pressure rollers, ensures that the object passes smoothly through the packaging crushing device while ensuring the pressure effect;

[0025] 2. The packaging mechanism of the present invention, using the aforementioned packaging crushing device, can recycle waste bottles. Regardless of whether the head or tail end of the waste bottle enters first, the gripping disc and the first pressure roller can cooperate to hook the end of the waste bottle, hooking the waste bottle in for initial and final pressure, ultimately flattening the waste bottle into a flat state, which facilitates the collection of waste bottles.

[0058] like Figure 1-24 As shown, this embodiment provides a packaging crushing device for applying pressure to an object 10. The packaging crushing device includes at least one set of pressure rollers 1 and at least one gripping disc 2. The pressure rollers 1 include two pressure rollers that cooperate in applying pressure, namely a first pressure roller 11 and a second pressure roller 12. The gripping disc 2 has a hook 211 formed on it. The gripping disc 2 cooperates with the first pressure roller 11 to hook the object 10. After the object 10 passes between the gripping disc 2 and the first pressure roller 11, the gripping disc 2 and the second pressure roller 12 cooperate to send the object 10 between the first pressure roller 11 and the second pressure roller 12. A pressure area is formed between the first pressure roller 11 and the second pressure roller 12. The object 10 is pressed through this pressure area and is finally crushed into a flat shape.

[0059] like Figure 3-7 As shown, the pressure wheel assembly 1 includes a first pressure wheel 11 and a second pressure wheel 12 that engage in pressure application. The first pressure wheel 11 and the second pressure wheel 12 mesh to apply pressure to the object 10.

[0060] The first pressure wheel 11 and the second pressure wheel 12 have basically the same structure. Taking the first pressure wheel 11 as an example, the structure of the pressure wheel is described. The first pressure wheel 11 includes a plurality of gears 111 arranged at intervals. The outer circumference of the gears 111 is evenly distributed with teeth 1111. The plurality of gears 111 are arranged at intervals on the gear shaft 112, and the teeth 1111 of the plurality of gears 111 are distributed in the same direction. A retaining ring 113 is provided between adjacent gears 111. The plurality of gears 111 and the retaining ring 113 are connected as a whole by a second fastener 114. Similarly, the second pressure wheel 12 also has the structure of gears, gear shaft, retaining ring, and second fastener, which will not be described in detail here.

[0061] As a preferred technical solution in this embodiment, the gear 111 and the gear shaft 112 adopt a keyway interference fit, and the gear shaft 112 can drive the gear 111 on it to rotate.

[0062] As a preferred technical solution in this embodiment, the teeth 1111 of the gear 111 have an involute profile, which can crush the object being pressed rather than break it.

[0063] As a preferred technical solution in this embodiment, the axial thickness of gear 111 is greater than the axial thickness of retaining ring 113.

[0064] As a preferred technical solution of this embodiment, the retaining ring 113 is ring-shaped, and a shaft hole 1131 is formed at the center of the retaining ring 113 to facilitate the keyway cooperation with the gear shaft 112; the retaining ring 113 has mounting holes 1132 distributed circumferentially to facilitate the passage of the second fastener 114.

[0065] As a preferred technical solution in this embodiment, the second fastener 114 may be, but is not limited to, a screwdriver. Multiple second fasteners 114 are provided and evenly arranged circumferentially.

[0066] The gripping disc 2 is located on the side of the pressure area entrance of the pressure wheel group 1. The gripping disc 2 includes multiple claw discs 21 arranged at intervals. Multiple hooks 211 are arranged along the circumferential direction on the claw disc 21. There are hook grooves 212 between adjacent hooks 211 in the circumferential direction. The multiple claw discs 21 are arranged at intervals on the claw disc shaft 22. The multiple claw discs 21 are arranged in the same position. Adjacent claw discs 21 are detachably connected by spacers 23. The multiple claw discs 21 arranged at intervals are connected into one piece by the first fastener 24.

[0067] As a preferred embodiment, the axial thickness of the claw disk 21 is relatively small, less than the axial thickness of the retaining ring 113 in the pressure wheel, so that the claws 211 of the claw disk 21 can extend into the adjacent gears 111 of the second pressure wheel 12. Preferably, the axial thickness of the claw disk 21 is 3-5 mm.

[0068] As a preferred technical solution in this embodiment, the claws 211 of the claw disk 21 are evenly arranged along the circumference of the claw disk 21, and the claws 211 are tilted along their own rotation direction.

[0069] As a preferred embodiment, the groove 212 formed between adjacent claws 211 includes a groove bottom 2121, a first groove wall 2122, and a second groove wall 2123. When the claw disk 21 rotates along the F3 direction, the first groove wall 2122 of the same groove 212 is located downstream of the second groove wall 2123. The junction between the claw 211 and the first groove wall 2122 serves to hook the pressure object 10. The groove bottom 2121 is a sloping groove bottom. The diameter of the junction between the groove bottom 2121 and the first groove wall 2122 is smaller than the diameter of the junction between the groove bottom 2121 and the second groove wall 2123. The maximum radial depth of the groove 212 is smaller than the maximum radial depth of the tooth groove between two adjacent teeth 1111 of the pressure wheel.

[0070] As a preferred embodiment, the spacer 23 has protrusions extending from both axial end faces, and the claw disk 21 has circumferentially distributed slots. The protrusions on the spacer 23 can be inserted into the slots of two adjacent claw disks 21, achieving a detachable connection with the claw disk 21. More preferably, the spacer 23 includes an outer spacer 231 and an inner spacer 232 coaxially arranged, with the inner spacer 232 spaced inside the outer spacer 231, and the first fastener 24 located between the outer spacer 231 and the inner spacer 232.

[0071] As a preferred technical solution in this embodiment, there are multiple first fasteners 24, which are evenly arranged in the circumferential direction. The first fasteners 24 can be selected from, but are not limited to, screws.

[0072] The gripping disc 2 engages with the first pressure wheel 11 and the second pressure wheel 12. The claws 211 of the gripping disc 2 are axially aligned with the teeth 1111 of the first pressure wheel 11, and there is partial meshing between the gripping disc 2 and the first pressure wheel 11. Figure 24 As shown, when the tooth 1111 of the first pressure wheel 11 extends into the groove 212 of the gripping disc 2, the tooth 1111 approaches the circumferential side of the groove 212, forming a meshing position B. There is a distance between the tooth 1111 and the other circumferential side of the groove 212. In addition, the maximum radial depth of the groove 212 is less than the maximum radial depth of the tooth groove between two adjacent teeth 1111 of the first pressure wheel, thus forming a region A. When the claw 211 hooks the end of the pressure object 10, the end of the pressure object 10 can be accommodated in region A, preventing the pressure object 10 from detaching. The claw 211 of the gripping disc 2 is axially offset from the tooth of the second pressure wheel 12, and the claw 211 can extend into the gap between the teeth of the second pressure wheel 12.

[0073] As a preferred technical solution of this embodiment, when the tooth 1111 of the first pressure wheel 11 can be inserted into the hook groove 212 of the gripping disk 2, the tooth 1111 approaches the second groove wall 2123 of the hook groove 212. One side of the tooth 1111 forms a meshing position B at the junction of the second groove wall 2123 and the bottom 2121 of the hook groove 212, which can initially apply pressure to the pressure object 10; the other side of the tooth 1111 is at a certain distance from the first groove wall 2122 of the hook groove 212, forming area A.

[0074] As a preferred embodiment, the number of teeth 1111 on the first pressure wheel 11, the number of teeth on the second pressure wheel 12, and the number of claws 211 on the gripping disk 2 are the same. Specifically, the number of teeth 1111 on each gear 111 of the first pressure wheel 11, the number of teeth on each gear of the second pressure wheel 12, and the number of claws 211 on each claw disk 21 of the gripping disk 2 are the same.

[0075] To prevent the object 10, after initial pressure application, from moving towards the gripping disc 2 and the second pressure wheel 12 without passing between the two pressure wheels, and also to prevent the object 10, after initial pressure application, from becoming stuck between two adjacent gripping discs 21 of the gripping disc 2 and causing blockage, a check structure 3 is provided between the gripping disc 2 and the second pressure wheel 12. The check structure 3 includes multiple check latches 31, and the check latches 31 are arranged in the interval between two adjacent gripping discs 21. The check latches 31 not only occupy the interval between the gripping discs 21, preventing the object 10 from becoming stuck between two adjacent gripping discs 21 of the gripping disc 2, but also block the entrance between the gripping disc 2 and the second pressure wheel 12, preventing the object 10 from moving towards the gripping disc 2 and the second pressure wheel 12.

[0076] As a preferred embodiment, the first side 311 of the anti-reverse buckle 31 near the first pressure wheel 11 includes a rejection section and a blocking section. The rejection section is a convex arc-shaped edge located between adjacent claw discs 21, and the blocking section is a concave arc-shaped edge protruding from the claw 211 of the claw disc 21. The rejection section can guide and peel off the pressure object 10 embedded in the gap of the claw disc 21, and the blocking section restricts the pressure object 10 from deviating from the two pressure wheels. The second side 312 of the anti-reverse buckle 31 near the second pressure wheel 12 is an arc-shaped edge extending parallel to the tooth tip circle R1 of the second pressure wheel 12. To prevent interference, there is a gap between the second side 312 and the tooth tip circle R1 of the second pressure wheel 12. The anti-reverse buckle 31 also has an arc-shaped third side 313, which is in clearance fit with the outer spacer 231 of the gripping disc 2.

[0077] In a preferred embodiment, the first side 311 and the second side 312 of the anti-reverse buckle 31 intersect to form a first intersection point P1. The tooth tip circle R1 of the second pressure roller 12 intersects with the stroke circle R2 of the claw 211 of the gripping disc 2 to form two intersection points. The intersection point closer to the first pressure roller 11 is the second intersection point P2. The first intersection point P1 is located outside the stroke circle R2 of the claw 211 of the gripping disc 2 and close to the second intersection point P2. Preferably, the distance from the first intersection point P1 to the second intersection point P2 is 6-10 mm.

[0078] As a preferred technical solution of this embodiment, multiple anti-return buckles 31 are spaced apart and assembled on the first connecting shaft 32. The first connecting shaft 32 can be set to two, and the two first connecting shafts 32 pass through all the anti-return buckles 31 to fix the anti-return buckles 31 in place.

[0079] To facilitate the collection of the pressure object 10 after passing through the pressure roller assembly 1, guide plates 4 are provided opposite to each other on the outlet side of the pressure area of ​​the pressure roller assembly 1. Guide plates 4 are mounted on opposite sides of the two pressure rollers of the pressure roller assembly 1. Specifically, a first guide plate 41 is provided on the side of the first pressure roller 11 facing the second pressure roller 12, and a second guide plate 42 is provided on the side of the second pressure roller 12 facing the first pressure roller 11.

Similarly, the second guide plate 42 has an inner side that is clearance-fitted with the retaining ring of the second pressure roller 12 and a guide side that plays a guiding role, which will not be described in detail here.

[0082] As a preferred technical solution in this embodiment, the first guide plate 41 and the second guide plate 42 have the same installation structure. Taking the first guide plate 41 as an example, the installation structure of the guide plate 4 is described. The first guide plate 41 is fixedly assembled by the installation assembly 43. The installation assembly 43 includes a connecting plate 431, a second connecting shaft 432, a fastening plate 433, and fasteners 434. The connecting plate 431 has a plurality of slots 4311 distributed parallel and at intervals. The plurality of first guide plates 41 can be partially inserted into the slots 4311.

[0083] The packaging crushing device also includes a conveyor belt 5, which delivers the object to be crushed 10 between the gripping disc 2 and the first crushing wheel 11.

[0084] To facilitate assembly, the packaging compaction device also includes a mounting frame 6. The mounting frame 6 comprises two side plates 61, a bottom plate 62, and a top plate 63. The two side plates 61 are parallel and spaced apart. The bottom plate 62 is fixedly connected to the bottom ends of the two side plates 61, and the top plate 63 is fixedly connected to the top ends of the two side plates 61. The interior of the mounting frame 6 forms a receiving space. The pressure roller assembly 1 and the gripping disc 2 are both assembled within the receiving space of the mounting frame 6. The two ends of the gripping disc 2's claw shaft 22 are rotatably mounted on the two side plates 61, respectively; the two ends of the first connecting shaft 32 of the check valve structure 3 are respectively mounted on the two side plates 61; and the two ends of the second connecting shaft 432 of the mounting assembly 43 are respectively mounted on the two side plates 61.

[0085] The drive assembly 7 is used to drive the pressure wheel assembly 1 and the gripping disc 2. The drive assembly 7 includes a drive device 71 and a transmission assembly 72. The drive device 71 drives the pressure wheel assembly 1 and the gripping disc 2 through the transmission assembly 72. In this embodiment, the transmission assembly 72 is a gear transmission assembly, which includes a cooperating driving gear and a driven gear. One end of the gear shaft 112 of the first pressure wheel 11 extends out of the side plate 61 and connects to the driving gear; one end of the claw disc shaft 22 of the gripping disc 2 extends out of the side plate 61 and connects to the driven gear. The drive device 71 drives the driving gear to rotate, thereby driving the first pressure wheel 11 and the gripping disc 2 to rotate. The second pressure wheel 12 rotates along with the first pressure wheel 11 because it meshes with it. Preferably, the transmission assembly 72 also includes a gear cover, which can cover the outside of the driving gear and the driven gear. Furthermore, besides the gear transmission assembly, the transmission assembly 72 can also be configured with other transmission structures.

[0086] To prevent blockage, at least one pressure wheel in the pressure wheel assembly 1 is elastically mounted, and the gap between the two pressure wheels in the pressure wheel assembly 1 can be adaptively adjusted. Since a transmission assembly 72 is mounted on the gear shaft 112 of the first pressure wheel 11, in this embodiment, the second pressure wheel 12 is elastically mounted. Specifically, elastic components 8 are respectively mounted on the outer sides of the two side plates 61, and the two sets of elastic components 8 are symmetrically arranged. Each elastic component 8 includes an outer frame 81, a fixed seat 82, a movable seat 83, and an elastic element 84. The fixed seat 82 and the movable seat 83 are disposed within the outer frame 81. The fixed seat 82 is fixed within the outer frame 81, and the movable seat 83 can slide within the outer frame 81. The movable seat 83 is located between the fixed seat 82 and the elastic element 84, and the elastic element 84 acts on the movable seat 83, providing a force to the movable seat 83 toward the fixed seat 82. The two ends of the gear shaft 112 of the first pressure wheel 11 are rotatably mounted on two fixed seats 82, and the two ends of the gear shaft of the second pressure wheel 12 are rotatably mounted on two movable seats 83. The elastic element 84 is optional, but not limited to, a spring.

[0087] As a preferred technical solution of this embodiment, the movable seat 83 has a plurality of elongated holes, and screws pass through the elongated holes to movably lock the movable seat 83 onto the side plate 61; the outer frame 81 has a plurality of elongated holes, and screws pass through the elongated holes to fix it onto the movable seat 83. The elongated holes on the movable seat 83 and the elongated holes on the outer frame 81 are parallel in length direction, so that the movable seat 83 can only move in a limited direction and within a limited range.

[0088] like Figure 25 As shown, this embodiment also provides a packaging mechanism, including a housing 20, a packaging crushing device placed inside the housing 20, and an inlet 201 provided on the housing 20. The object to be crushed 10 put in through the inlet 201 can be conveyed to the gripping disc 2 and the pressure wheel set 1 by the conveyor belt 5. The gripping disc 2 and the pressure wheel set 1 cooperate to apply pressure to the object to be crushed 10, which facilitates the recycling and collection of the object to be crushed.

[0089] As a preferred technical solution in this embodiment, the pressure object 10 is a plastic bottle.

[0090] Based on the above technical solution, the working process of the packaging crushing device in this embodiment is as follows: Figure 5 As shown, the first pressure wheel 11 rotates in the F1 direction, the second pressure wheel 12 rotates in the F2 direction, and the gripping disc 2 rotates in the F3 direction.

[0091] The object under pressure 10 is conveyed via conveyor belt 5 to the space between gripping disc 2 and first pressure roller 11, such as... Figure 24As shown, the teeth 1111 of the first pressure roller 11 lift the object 10 being pressured towards the gripping disc 2, so that the claws 211 of the gripping disc 2 can hook the end of the object 10 being pressured. The end of the object 10 being pressured is limited within region A, and the gripping disc 2 and the first pressure roller 11 can smoothly hook the object 10 being pressured. Because there is a meshing position B between the gripping disc 2 and the first pressure roller 11, the object 10 being pressured will be initially pressured by the gripping disc 2 and the first pressure roller 11.

[0092] The claw 211 of the gripping disc 2 hooks the end of the object 10 to be pressed and continues to move to the check structure 3. The check buckle 31 blocks the end of the object 10 to be pressed, preventing it from continuing to move with the claw 211. At this time, the end of the object 10 is located within the range of the tooth tip circle R1 of the second pressure wheel 12. The teeth of the second pressure wheel 12 can drive the object 10 to the entrance of the pressure area of ​​the two pressure wheels. The pressure wheel group 1 applies pressure to the object 10.

[0093] The object being pressed 10 is flattened and leaves the pressure area under the guidance of the first guide plate 41 and the second guide plate 42.

[0094] The packaging crushing device of this embodiment can achieve efficient crushing of the object 10. Regardless of whether the front or rear end of the object 10 reaches the gripping disc 2 and the first pressing wheel 11 first, the claws 211 of the gripping disc 2 and the teeth 1111 of the first pressing wheel 11 can cooperate to make the object 10 smoothly enter the crushing area without slipping or popping out.

[0095] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
