Description

Technical Field

[0001] This invention relates to the field of material recycling, and more particularly to plastic recycling equipment for processing plastic parts. Background Technology

[0002] With increasing environmental awareness, various industries are adopting green and environmentally friendly production technologies. However, for single-use or limited-use products such as beverage bottles, plastic is the most cost-effective material. Therefore, to avoid environmental impact, various plastic recycling programs have been designed, typically involving steps such as recycling, cleaning, crushing, processing, and re-granulation. However, for plastic bottles, since the bottle surface is not only made of plastic but also includes the outer packaging tape and bottle cap, manual sorting is required during recycling before further processing. Manually separating the bottle cap and packaging tape is not only inefficient but also has high overall labor costs. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides the following technical solution: Plastic recycling equipment for processing plastic parts includes: a mounting plate, a cutting and compression assembly disposed on the upper surface of the mounting plate, and a cap removal assembly disposed at the center of the mounting plate.

[0004] Specifically, the upper surface of the mounting plate is provided with a positioning element, and the positioning element has a through-hole groove in the middle. The cutting and compression assembly includes at least a retractable pressure head and a cutter. The cap removal assembly includes a retractable and rotatable pin along the axis. The center of the pin, the bottle neck groove, and the pressure head are located on the same horizontal axis. The blade of the cutter is on the same plane as the axis.

[0005] As an improvement to the above technical solution, the following is provided: a frame, the frame including a base frame and a positioning cover, the positioning cover being a hollow ring-shaped shell fixed to the upper end face of the base frame, the mounting plate including at least two ring frames with an L-shaped cross section, the concave side of the ring frame fitting the outer side wall and inner side wall of the positioning cover, the two ring frames being concentrically arranged and connected by fixed connecting ribs.

[0006] As an improvement to the above technical solution, a motor unit is provided on one side of the base frame, and a synchronous belt is connected to the power end of the motor unit. The synchronous belt is wound around the outer surface of the outer ring frame. At least one unloading groove is provided on the upper end face of the positioning cover. A through groove is provided in the center of the positioning cover. The bottle cap removed by the needle is removed from the groove. A receiving cylinder is detachably provided below the unloading groove and the groove.

[0007] As an improvement to the above technical solution, the bottle mouth groove is frustum-shaped, with the smaller opening facing the insertion pin, and the inner wall of the bottle mouth groove is filled with a soft elastic layer.

[0008] As an improvement to the above technical solution, the cutting and compression assembly includes a telescopic rod, the pressure head is fixed to the power end of the telescopic rod, the cutter is L-shaped and fixed to the side of the telescopic end of the telescopic rod, the end face of the positioning member is provided with a through slot, and when the pressure head completely squeezes the plastic part, the cutter is inserted into the inside of the slot, the upper end face of the mounting plate is provided with a mounting plate, and the telescopic rod is fixed to the inner side of the mounting plate.

[0009] As an improvement to the above technical solution, a side groove is provided on one side of the positioning component, and a negative pressure pump is provided inside the side groove. One end of the negative pressure pump is connected to the inside of the bottle mouth groove, and the other side of the negative pressure pump is connected to an air pipe, which faces the cutting line of the cutter.

[0010] As an improvement to the above technical solution, the cutting and compression assembly includes a motor and a second telescopic rod. The second telescopic rod is fixed to the rotating end of the motor, and the telescopic end of the second telescopic rod is fixed to the pin.

The motor is located inside the installation groove, and a positioning sleeve with the same number of pins is rotatably provided on the outside of the base. A pin hole is opened at the end of the positioning sleeve, and the pins extend and retract in the pin hole.

[0012] As an improvement to the above technical solution, the interior of the central groove is provided with reinforcing ribs, a central column is provided at the center of the reinforcing ribs, and a slot is opened at the bottom of the base, into which the central column is inserted.

[0013] As an improvement to the above technical solution, the number of unloading troughs is two, the number of cutting and compression components and positioning components is several, and they are evenly distributed in a ring on the surface of the mounting plate. The cap removal component has the same number of pins as the cutting and compression components.

[0014] The beneficial effects of this invention are: By incorporating cutting and compression components, pins, and other structures, an automatic separation function for plastic bottles is achieved. This allows for the separate separation of the bottle cap, bottle packaging tape, and bottle body, ensuring proper compression of the bottle. Furthermore, each separated component is stored separately to prevent interference between them. The solution described in this invention solves the problem of low efficiency in manual sorting through automated processing. Moreover, the overall cost of this solution is low, effectively alleviating the cost issues associated with manual processing. Attached Figure Description

[0017] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0018] For plastic bottles, since the surface of the bottle body is not only made of plastic, but also includes the outer packaging tape and the bottle cap, manual sorting is required during recycling before further processing. Manually separating the bottle cap and bottle body packaging tape is not only inefficient, but also has high overall labor costs.

[0019] To resolve the above issues, please refer to Figures 1 to 9 A plastic recycling device for processing plastic parts is provided, comprising: a mounting plate 20, a cutting and compression assembly 30 disposed on the upper end face of the mounting plate 20, and a cap removal assembly 40 disposed at the center of the mounting plate 20.

[0020] Specifically, the upper surface of the mounting plate 20 is provided with a positioning member 22, and the middle of the positioning member 22 is provided with a through bottle neck groove 221. The cutting and compression assembly 30 includes at least a retractable pressure head 32 and a cutter 33. The cap removal assembly 40 includes a retractable and rotatable pin 43. The center of the pin 43, the bottle neck groove 221 and the pressure head 32 are located on the same horizontal axis, and the blade of the cutter 33 is on the same plane as the axis.

[0021] When using the device, first insert the bottle neck into the positioning member 22. The bottle neck groove 221 of the positioning member 22 will initially stabilize the bottle. It is not necessary to completely stabilize the bottle neck. Then, control the pressure head 32 and the cutter 33 to move towards the bottle and initially squeeze the bottle. At this time, the cutter 33 and the pressure head 32 can contact the bottle body. The cutter 33 will cut the bottle surface during the movement, while the pressure head 32 can initially stabilize the bottle body. After the cutter 33 cuts one side of the bottle body, the pressure head 32 will continue to squeeze, thereby flattening the bottle body. After the cutter 33 cuts the bottle, the bottle packaging tape wrapped around the outside of the bottle body will also be cut and fall off.

[0022] Of course, with this structural design, firstly, the bottle opening may not be stable enough; secondly, during the cutting process, since the pressure head 32 does not contact the bottle body first, the cutting effect may not be good enough. Regarding this contact, this application provides the following design: A side groove 222 is provided on one side of the positioning component 22. A negative pressure pump 224 is installed inside the side groove 222. One end of the negative pressure pump 224 is connected to the inside of the bottle mouth groove 221. The other side of the negative pressure pump 224 is connected to an air pipe 225, which faces the cutting line of the cutter 33.

[0023] The bottle is fixed by a negative pressure pump 224 on the side of the positioning component 22. The negative pressure suction can hold one side of the bottle, ensuring the bottle has relative stability when the cutter 33 squeezes it, thus completing the cutting function normally. In addition, the air outlet of the negative pressure pump 224 is connected to an air pipe 225. After the bottle packaging tape is cut, the air pipe 225 can blow the packaging tape away, thus separating it from the bottle. This way, the packaging tape will not affect the subsequent squeezing of the bottle by the pressure head 32, ensuring the separation of the bottle from the packaging tape throughout the entire operation.

[0024] Furthermore, the aforementioned technical solution does not impose any restrictions on the bottle neck groove 221. Since the bottle neck is generally relatively small, in this embodiment, the bottle neck groove 221 is set as a frustum shape, and the side inclination angle of the frustum is set within a small range. If it is too large, it will cause the bottle body to be unable to be clamped properly. Due to the setting of the air tube 225 and the negative pressure pump 224, it is also necessary to ensure that the bottle inserted inside forms a relatively closed connection with the bottle neck groove 221. On this basis, a soft elastic layer can be filled inside the bottle neck groove 221. In this way, the inserted bottle neck will squeeze the soft elastic layer, thereby forming a deformation filling gap. In this way, a relatively closed connection is formed inside. Thus, the suction of the negative pressure pump 224 can firmly suction the bottle neck. In addition, in order to ensure the stable docking of the bottle neck groove 221 with the bottle neck, the small opening side is oriented towards the direction of the insertion pin 43. In this way, the operator only needs to push the bottle neck into the bottle neck groove 221, and the remaining operations can be performed automatically by the machine.

[0025] In this embodiment, the mounting plate 20 is not an independent component; it requires a corresponding support structure to achieve its overall erection. In this embodiment, the support structure is designed as a frame 10, as detailed below: The frame 10 includes a base frame 11 and a positioning cover 12. The positioning cover 12 is a hollow ring-shaped shell fixed to the upper surface of the base frame 11. The mounting plate 20 includes at least two ring frames 21 with an L-shaped cross section. The recessed side of the ring frame 21 is attached to the outer side wall and inner side wall of the positioning cover 12. The two ring frames 21 are concentrically arranged and connected by a fixed connecting rib 212.

[0026] The mounting plate 20 is fixed and fastened by two L-shaped ring frames 21. This connection method facilitates subsequent disassembly and maintenance operations and reduces the connection relationship between structural components. The two ring frames 21 are connected by connecting ribs 212, which creates a large space between the two ring frames 21. During the operation, the bottle packaging tape and the squeezed bottle can fall through the space. In this process, it is only necessary to divide the space below into several non-connected cavities by partitions to ensure that after the cutting and separation steps are completed, each corresponding separation component can be accurately separated in different areas, thereby completing the separation operation.

[0027] In addition, in this embodiment, the connecting rib 212 can be designed with an acute or obtuse angle on its upper end face. This way, the packaging tape and bottle body will not fall on the connecting rib 212 after being cut and separated, thus avoiding the problem of processing blockage.

[0028] In the aforementioned technical solution, the entire equipment is in a fixed state, which is inconvenient for operators. To facilitate material loading, this embodiment provides the following design: A motor unit 23 is provided on one side of the base frame 11. The power end of the motor unit 23 is connected to a synchronous belt 24. The synchronous belt 24 is wound around the outer surface of the outer ring frame 21. At least one unloading groove 121 is provided on the upper end face of the positioning cover 12. A through groove 122 is provided in the center of the positioning cover 12. The bottle cap removed by the needle 43 is removed from the groove 122. A receiving cylinder 124 is detachably provided below the unloading groove 121 and the groove 122.

[0029] The synchronous belt 24 is controlled to rotate by setting the motor unit 23 on the outside. The rotating synchronous belt 24 transmits the rotational power to the ring frame 21. Since the ring frame 21 is fitted on the positioning cover 12, the ring frame 21 can rotate under this design. In this way, the loading personnel or loading machine only need to load the material in a fixed position. After the loading is completed, the positioning part 22 will rotate to another position for processing, and after the processing is completed, it will rotate back to the previous position and wait for the next loading. Based on the fact that the entire ring frame 21 can rotate, by controlling the ring frame 21 to stop at different positions or designing a larger falling space, the packaging belt and bottle body can fall at different positions, thereby completing the material collection operation.

[0030] In this embodiment, at least one unloading trough 121 is designed for receiving materials. Of course, if it is for separation operation, the number of unloading troughs 121 is set to two, one to collect the cut and blown-off packaging tape, and the other to collect the compressed bottle. In this embodiment, the compression of the bottle cannot reach the limit. If it is to manufacture an extremely compressed block like a plastic brick, it is necessary to perform separate compression processing in subsequent operations.

[0031] In the above technical solution, since the bottle mouth is inserted into the bottle mouth groove 221, the pin 43 can be unscrewed by rotating after being inserted into the bottle cap. By simply controlling the pin 43 to retract, the bottle cap can be moved into the range of the middle groove 122. In this way, removing the bottle cap can separate the bottle cap from the other two parts, thereby completing the purpose of unpacking a complete bottle body.

[0032] In addition, in order to ensure uninterrupted processing in this embodiment, the number of cutting and compression components 30 and positioning components 22 is several, and they are evenly distributed in a ring on the surface of the mounting plate 20. The cap removal component 40 has the same number of pins 43 as the cutting and compression components 30.

[0033] By setting up multiple sets of corresponding separation structures, the feeding structure can continuously feed materials, and the processing time can be distributed through other equipment. This eliminates the need to wait for each processing step, thus achieving continuous processing.

[0034] In this embodiment, the design of the cutting and compression component 30 is as follows: The cutting and compression assembly 30 includes a telescopic rod 31, a pressure head 32 fixed to the power end of the telescopic rod 31, and an L-shaped cutter 33 fixed to the side of the telescopic end of the telescopic rod 31. The end face of the positioning member 22 has a through slot 223. When the pressure head 32 completely compresses the plastic part, the cutter 33 is inserted into the inside of the slot 223. The upper end face of the mounting plate 20 is provided with a mounting plate 211, and the telescopic rod 31 is fixed to the inside of the mounting plate 211.

[0035] The integrated pressure head 32 works in conjunction with the cutter 33, and the telescopic rod 31 provides the main extension power. When the bottle is fixed in the bottle neck groove 221, the telescopic rod 31 extends, and the cutter 33 first contacts the bottle body and provides a certain cutting effect. The surface of the bottle body is cut open. When it encounters the packaging tape covering the bottle body, the blade of the cutter 33 will cut the packaging tape. In this embodiment, the cutter 33 is positioned directly above, and the air blowing position is also directly above. Here, the position of the air pipe 225 can be adjusted to avoid mutual interference between the two. During this process, the airflow blown by the air pipe 225 of the negative pressure pump 224 will blow on the cut position, so that the cut packaging tape falls from above. In addition, during the movement, the cutter 33 will be inserted into the slot 223 without affecting the positioning member 22 or the overall strength of the positioning member 22. During the overall operation, the telescopic rod 31 is fixed on the mounting plate 211, so the telescopic rod 31 and the corresponding connected structures move synchronously with the mounting plate 20.

[0036] The aforementioned technical solution did not specify the exact structure of the cover removal component 40. To ensure the completeness and usability of this technical solution, the following design is provided in this embodiment: The cutting and compression assembly 30 includes a motor 41 and a telescopic rod 42. The telescopic rod 42 is fixed to the rotating end of the motor 41, and the telescopic end of the telescopic rod 42 is fixed to the pin 43.

[0037] The telescopic rod 42 is rotated by the motor 41, and the insertion of the pin 43 is controlled by the extension and retraction of the telescopic rod 42. When removing the cap, the pin 43 is first inserted into the end face of the cap by the telescopic rod 42, and then the rotation of the motor 41 causes the pin 43 to rotate, thereby driving the cap to rotate. This achieves the separation of the cap. In this embodiment, the separation of the cap can be performed synchronously with the telescopic rod 31. This is to ensure that there is an external force to block the insertion of the pin 43, so as to prevent the pin 43 from directly pushing the entire bottle body out of the bottle mouth groove 221. During the cap removal process, the rotating cap will cause some pressure on the bottle mouth, but since the bottle body is plastic, it will not affect the cap removal work.

[0038] In this embodiment, the needle 43 adopts a needle shape with certain ridges and grooves, such as three sides or a cross. This ensures that after being inserted into the bottle cap, it can form a squeeze with the bottle cap, thereby ensuring that the rotating needle 43 can drive the bottle cap to rotate. The number of ridges and grooves should not be too many, because after insertion, it may cause the cut to be small and easily deformed. This problem will cause the needle 43 to not be able to drive the bottle cap to complete a complete rotation when rotating.

[0039] In one embodiment, the installation and fixing of the motor 41, pin 43, and corresponding structural components also need to be considered. Based on this, this embodiment provides the following design: The interior of the middle slot 122 is provided with a rotatable base 44. The surface of the base 44 has an opening and closing mounting groove 441. The motor 41 is located inside the mounting groove 441. The outer side of the base 44 is rotatably provided with a positioning sleeve 442 with the same number as the pins 43. The end of the positioning sleeve 442 is provided with a pin hole 443, and the pins 43 extend and retract in the pin hole 443.

[0040] The base 44 is designed separately to provide the overall installation structure. The motor 41 is installed through the mounting slot 441. In addition, a dust cover can be set at the end of the slot for protection. The end of the motor 41 is connected to the telescopic rod 42, which extends to the outside of the base 44. The pin 43 at the end of the telescopic rod 42 is located outside the base 44. The positioning sleeve 442 and the pin hole 443 on the positioning sleeve 442 are used to remove the bottle cap from the pin 43. After the pin 43 removes the bottle cap, the bottle cap is stuck on the pin 43. At this time, it is only necessary to control the pin 43 to continue to retract inward until the bottle cap contacts the positioning sleeve 442 to realize the push-type unloading function, so that the bottle cap falls directly into the middle tank 122, thereby completing the automatic unloading operation of the bottle cap.

[0041] In this embodiment, the rotation setting adopts an insert bearing connection. The positioning sleeve 442 is fixed by opening a round hole on the side and installing a bearing in the round hole. In this way, the positioning sleeve 442 can achieve the function of rotating around its own axis with the help of external force while ensuring that the position remains unchanged.

[0042] After the bottle cap is separated, the telescopic rod 31 continues to squeeze and completes the squeezing operation on the bottle body. Since the bottle body is squeezed, the bottle mouth is no longer in a cavity state as before. Therefore, by controlling the telescopic rod 42 to continue to extend, the entire compressed bottle body can be pushed out of the bottle mouth groove 221 through the pin 43, completing the final unloading operation on the bottle body.

[0043] In this embodiment, the rotation function of the entire cover removal assembly 40 is further considered. In order to reduce the complexity of the structural components and ensure the synchronization of operation between the structural components, the design of its rotation structure in this embodiment is as follows: The interior of the central groove 122 is provided with a reinforcing rib 123, and a central column 125 is provided at the center of the reinforcing rib 123. The bottom of the base 44 is provided with a slot, and the central column 125 is inserted into the slot.

[0044] The base 44 is directly mounted on the central column 125. The purpose here is to drive the entire base 44 to rotate by rotating the mounting plate 20. Although this purpose can be achieved, it requires high strength for the pins 43, so a higher strength material is needed. In addition, in this embodiment, a bearing can be installed inside the groove at the bottom of the base 44 to reduce the resistance to the rotation of the base 44, thereby reducing the torsional force caused by the connection of the pins 43 and extending the service life of the pins 43. In this embodiment, the most suitable motor for the motor assembly 23 is a stepper motor and a gearbox. The stepper motor can control the number of rotations of the motor assembly 23 in a fixed step size, and the gearbox reduces the speed, thereby achieving the purpose of controlling the mounting plate 20 to rotate at a fixed angle, ensuring periodic pauses of several seconds for feeding equipment or personnel to perform feeding operations.

[0045] The above embodiments are merely illustrative of the technical solutions of the present invention and are not intended to limit it. Anyone skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
