Description

Technical Field

[0001] This utility model relates to the field of plastic film scrap recycling technology, specifically a scrap winding, crushing and recycling device. Background Technology

[0002] Plastic films are made from various resin materials such as polyvinyl chloride, polyethylene, polypropylene, and polystyrene, and are widely used in packaging and lamination. In the field of plastic packaging, especially composite flexible plastic packaging, they occupy an important position in industries such as food, pharmaceuticals, and chemicals, particularly in food packaging, including beverages, frozen foods, cooked foods, and fast foods. These packaging materials greatly facilitate people's lives. The production process of plastic films generates some waste. To reduce resource waste, this waste is usually recycled.

[0003] Extensive searches revealed CN220446922U, which discloses a waste recycling device for plastic film processing. The device includes a frame, a sliding plate fixedly connected to the bottom of the inner cavity of the frame, a support frame slidably connected to the top of the sliding plate, a slidably connected outer surface of the support frame to the frame, and universal wheels movably connected to the four corners of the bottom of the support frame, with the bottom of the universal wheels tightly fitted to the frame.

[0004] In existing technologies, the cut plastic film needs to be manually collected and placed into a recycling device for crushing. However, the scraps formed after the roll is cut also need to be collected in time. If they are not recycled in time, they will be mixed into the normal finished roll, causing sorting difficulties. To address this, a scrap rolling and crushing recycling device is proposed to promptly recycle plastic film scraps and also has a crushing function, thereby solving the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a scrap material winding, crushing and recycling device, which has the advantages of automated collection and crushing of plastic film scraps, and solves the problems of low efficiency of manual collection and difficulty in sorting caused by scraps being mixed into finished rolls.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a scrap material winding, crushing and recycling device, including a base, a winding mechanism fixedly installed on the base, a cutting mechanism fixedly installed on the top back of the base, the winding mechanism including a servo motor, the servo motor being fixedly connected to the base, a winding rod being driven and installed at one end of the servo motor, and the winding rod being rotatably installed inside the base;

[0007] The cutting mechanism includes a cutting frame, which is movably mounted on a winding rod inside the base. Cutting blades are fixedly installed in a circular array inside the cutting frame. The side of the cutting blades facing away from the cutting frame contacts the outer wall of the winding rod but is not fixedly connected.

[0008] Preferably, the base includes a base frame, and a baffle is fixedly installed on the front of the base frame. The top of the baffle is lower than the bottom of the cutting frame. In this design, the baffle can effectively guide the cut scraps directly into the collection box, avoiding the scattering of scraps in the work area, maintaining a clean working environment, and reducing the amount of manual cleaning work.

[0009] Preferably, the cutting mechanism further includes a drive motor, which is fixedly mounted on the top side of the back of the base frame via a mounting bracket. A lead screw is driven to one end of the drive motor. In this design, the drive motor provides a precise power source, enabling precise movement of the cutting frame via the lead screw, ensuring the accuracy and consistency of the cutting, and improving the overall efficiency and reliability of the device.

[0010] Preferably, a slider is threaded onto the lead screw, and a mounting base is rotatably mounted on the end of the lead screw away from the drive motor. The mounting base is fixedly mounted on the top of the other side of the back of the base frame. In this design, the cooperation between the slider and the lead screw enables the smooth movement of the cutting frame, reduces vibration and noise during the cutting process, and improves the cutting accuracy, ensuring neat cutting of scrap materials.

[0011] Preferably, the front of the slider is fixedly connected to the rear end of the cutting frame, and the front end of the slider is located inside the base frame. This design achieves effective linkage between the cutting frame and the drive motor through the fixed connection between the slider and the cutting frame, making the cutting action more stable and precise. It also simplifies the structure of the device and facilitates maintenance and repair.

[0012] Preferably, the winding rod has a pre-reserved groove with a cross-shaped cross section, and the winding rod is parallel to and does not contact the lead screw. The parallel layout of the winding rod and the lead screw in the design ensures that the two components can be operated independently without interfering with each other. At the same time, the design of the pre-reserved groove facilitates the fixing of scrap materials, improves the winding efficiency and stability, and ensures the continuous winding and timely cutting of scrap materials.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] The winding mechanism of this invention includes a servo motor, which is fixedly connected to the base and has a winding rod mounted on one end. The precise control capability of the servo motor enables the winding rod to rotate stably and continuously, achieving automatic winding of scrap materials. This automated winding process reduces manual intervention and improves collection efficiency. A cutting mechanism is fixedly installed on the top of the back of the base, including a cutting frame that is movably fitted onto the winding rod inside the base. This design allows the cutting frame to slide along the winding rod for cutting operations when needed. Cutting blades are fixedly installed in a circular array inside the cutting frame. These cutting blades contact the outer wall of the winding rod and can cut the scrap materials in a timely manner during the winding process, facilitating the removal of the cut scrap materials. Due to the coordinated work of the winding rod and the cutting frame, the scrap materials can be cut immediately after being wound, achieving continuous processing of scrap materials. The automated winding and cutting process reduces the need for manual operation, lowers labor intensity, and improves production efficiency. Because scrap materials are handled promptly and effectively, the quality of the finished roll material is guaranteed, reducing quality problems caused by scrap materials being mixed in. Furthermore, automated operation reduces the chances of people directly contacting scrap materials and cutting tools, thereby reducing safety risks during operation. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, one embodiment of this utility model is provided: a scrap material winding, crushing and recycling device, including a base 1, a winding mechanism 2 fixedly installed on the base 1, a cutting mechanism 3 fixedly installed on the top back of the base 1, the winding mechanism 2 includes a servo motor 21, the servo motor 21 is fixedly connected to the base 1, and a winding rod 22 is driven and installed at one end of the servo motor 21, the winding rod 22 is rotatably installed inside the base 1.

[0023] The cutting mechanism 3 includes a cutting frame 36, which is movably mounted on a winding rod 22 inside the base 1. Cutting blades 361 are fixedly installed in a ring array inside the cutting frame 36. The side of the cutting blades 361 facing away from the cutting frame 36 contacts the outer wall of the winding rod 22 but is not fixedly connected.

[0024] Specifically, the winding mechanism 2 includes a servo motor 21, which is fixedly connected to the base 1 and has a winding rod 22 mounted on one end. The precise control capability of the servo motor 21 enables the winding rod 22 to rotate stably and continuously, achieving automatic winding of scrap materials. This automated winding process reduces manual intervention and improves collection efficiency. A cutting mechanism 3 is fixedly mounted on the top of the back of the base 1, including a cutting frame 36, which is movably fitted onto the winding rod 22 inside the base 1. This design allows the cutting frame 36 to slide along the winding rod 22 for cutting operations when needed. Cutting blades 361 are fixedly mounted in a circular array inside the cutting frame 36. These cutting blades 361 contact the outer wall of the winding rod 22 and can cut the scrap materials in time during the winding process, thus facilitating the removal of the cut scrap materials. Due to the coordinated work of the winding rod 22 and the cutting frame 36, the scrap materials can be cut immediately after being wound, achieving continuous processing of scrap materials. Automated winding and cutting processes reduce the need for manual operation, lower labor intensity, and improve production efficiency. Because scrap is handled promptly and effectively, the quality of the finished roll material is guaranteed, reducing quality problems caused by scrap contamination. Furthermore, automation reduces direct human contact with scrap and cutting tools, thereby lowering safety risks during operation.

[0025] Example 2

[0026] To improve the stability of the cutting mechanism during movement and to facilitate the winding and positioning of cut scraps during use, such as Figure 1 and Figure 2As shown, in this embodiment, the base 1 includes a base frame 11, and a baffle 12 is fixedly installed on the front of the base frame 11. The top height of the baffle 12 is lower than the bottom height of the cutting frame 36. In this design, the baffle 12 can effectively guide the cut scraps directly into the collection box, avoiding the scattering of scraps in the work area, keeping the work environment clean, and reducing the amount of manual cleaning work.

[0027] Furthermore, the cutting mechanism 3 also includes a drive motor 31, which is fixedly mounted on the top side of the back of the base frame 11 via a mounting bracket 32. A lead screw 34 is mounted on one end of the drive motor 31. In this design, the drive motor 31 provides a precise power source, and the lead screw 34 enables precise movement of the cutting frame 36, ensuring the accuracy and consistency of the cutting and improving the overall efficiency and reliability of the device.

[0028] Furthermore, a slider 33 is threaded onto the lead screw 34, and a mounting base 35 is rotatably mounted on the end of the lead screw 34 away from the drive motor 31. The mounting base 35 is fixedly mounted on the top of the other side of the back of the base frame 11. In this design, the cooperation between the slider 33 and the lead screw 34 enables the smooth movement of the cutting frame 36, reduces vibration and noise during the cutting process, and improves the cutting accuracy, ensuring neat cutting of scraps.

[0029] Furthermore, the front of the slider 33 is fixedly connected to the rear end of the cutting frame 36, and the front end of the slider 33 is located inside the base frame 11. The fixed connection between the slider 33 and the cutting frame 36 in this design achieves effective linkage between the cutting frame 36 and the drive motor 31, making the cutting action more stable and precise. It also simplifies the structure of the device, facilitating maintenance and repair.

[0030] Furthermore, a pre-reserved slot 221 with a cross-shaped cross section is provided on the winding rod 22. The winding rod 22 is parallel to and does not contact the lead screw 34. The parallel layout of the winding rod 22 and the lead screw 34 in the design ensures that the two components can be operated independently without interfering with each other. At the same time, the design of the pre-reserved slot 221 facilitates the fixing of scrap materials, improves the efficiency and stability of winding, and ensures the continuous winding and timely cutting of scrap materials.

[0031] In use, the collection box is placed on the base frame 11 below the winding rod 22 to collect the cut scraps. One end of the cut plastic film scraps is manually pulled and fixed to the winding rod 22 through the pre-reserved groove 221. The servo motor 21 starts to rotate, driving the winding rod 22 to wind up the scraps. When a certain amount is wound, the cutting mechanism 3 operates and cuts the scraps wound on the winding rod 22 with the cutting blade 361 installed on the cutting frame 36. The cut scraps fall into the collection box, and new scraps can be re-fixed on the winding rod 22 to continue winding and cutting. Throughout the process, it is necessary to ensure that the rotation speed of the servo motor 21 matches the speed of plastic film cutting to maintain continuous winding and timely cutting of the scraps. After the scraps in the collection box accumulate to a certain amount, they will be sent to a subsequent, more refined crushing device for crushing. After a certain cycle of work is completed, the power is turned off, and the device is cleaned and maintained to ensure efficiency and safety for the next use.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
