Description

Technical Field

[0001] This utility model relates to the field of PVC sheet cutting, and in particular to a device for collecting and recycling scraps from PVC sheet cutting. Background Technology

[0002] PVC sheets are flat, flexible plastic products made primarily from polyvinyl chloride (PVC) resin through processes such as extrusion and calendering. Their thickness typically ranges from 0.1 mm to several millimeters, and their hardness, color, and properties (such as weather resistance and transparency) can be adjusted by adding plasticizers, stabilizers, colorants, and other additives. PVC sheets are an important base material for producing advertising display boards, stationery packaging, equipment gaskets, furniture edge banding, and other products.

[0003] While existing technologies can achieve some collection and processing of PVC scraps after cutting, they have drawbacks: traditional PVC cutting and collection methods result in scraps being mixed with dust and debris, incomplete cleaning, severe dust generation during operation, and high levels of manual intervention and inefficiency. In view of this, we propose a PVC sheet cutting scrap collection and recycling device that solves the above problems. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a device for collecting and recycling scraps from PVC sheet cutting.

[0005] The technical solution of this utility model: A PVC sheet cutting scrap collection and recycling device includes a box, a receiving plate, a moving trough and a collection trough. The receiving plate is rotatably installed at the lower end of the box. A discharge port is opened on the surface of the box on one side of the receiving plate. A linear motor is provided at the lower end of the discharge port. A slot is provided below the receiving plate. A moving trough is inserted into the slot. A nozzle distributed in a square array is provided at the upper end of the moving trough. A groove is opened between the nozzles. A collection trough is inserted into one side of the moving trough. The collection trough is connected to the groove. When using this device, the opening at the top of the box can be positioned at the discharge port of the slitting device. After the material is slitted, the scraps fall into the box and are caught by the receiving plate. The negative pressure machine inside the device is activated when the moving trough is inserted into the box, preventing dust or debris from being scattered. The nozzle at the top of the moving trough, in conjunction with the pulse device, sprays gas intermittently from below the receiving plate, blowing out the debris remaining between the material scraps (but not outside the box). After being blown out, the debris is immediately sucked into the groove by the negative pressure and falls into the collection tank. The operator only needs to periodically remove the moving trough and collection tank to clean the debris. Other scraps remaining at the top of the receiving plate can be tilted by the linear motor and discharged from the discharge port. This device can conveniently collect scraps after slitting PVC sheets, reducing debris and dust, and has high practicality.

[0006] Preferably, the box body is fixed with supports on both sides and a base is fixed at the lower end of the supports. By setting the supports and the base, the stability and reliability of the entire device are enhanced, so that it can be placed firmly below the discharge port of the slitting machine, avoiding displacement or tipping due to equipment vibration or operational impact, and ensuring the continuity and safety of the collection process.

[0007] Preferably, a negative pressure unit is provided on one side of the collection trough, with the housing of the negative pressure unit exposed on the outer wall of the moving trough. A handle is provided on one side of the moving trough, and the negative pressure unit is connected to the collection trough. Integrating the negative pressure unit into the outer wall of the moving trough creates a highly efficient negative pressure air duct design, allowing the generated negative pressure suction to act on the groove area with the shortest path and highest efficiency, greatly improving the dust collection effect. The handle makes it easy for workers to pull out the entire moving debris removal module (including the moving trough, collection trough, and negative pressure unit), realizing the modularization and convenience of the debris collection function, and facilitating regular cleaning and maintenance.

[0008] Preferably, a pulse generator is fixed to one side of the nozzle. The pulse generator, in conjunction with the rear-end controller, controls each nozzle to spray pulsed airflow. By using the pulse generator to control the nozzle to spray intermittent, high-intensity pulsed airflow, rather than continuous blowing, this design has significant advantages: First, it achieves the best dust removal effect with the least amount of air, and the strong airflow impact can effectively shake off tightly attached debris; Second, it avoids the disorderly flying of dust in the chamber caused by continuous airflow. The short intervals of waiting for negative pressure suction ensure that dust is controllable, improving cleaning efficiency and reducing energy consumption.

[0009] Preferably, a rotating plate is rotatably mounted at the lower end of the discharge port, and a linear motor is embedded in the middle of the rotating plate. The upper end of the linear motor has an output end, which is rotatably connected to the lower surface of the receiving plate. This structural design provides a stable and powerful driving solution. By pushing a specific point on the lower surface of the receiving plate, the linear motor can lift the receiving plate with precise and controllable force and angle, making it tilt smoothly. This solves the problems of large impact and low precision that may exist in traditional cylinder or hydraulic rod drives, ensuring that scrap materials can slide out of the discharge port smoothly and evenly, preventing blockage at the outlet.

[0010] Preferably, the surface of the receiving plate is provided with through holes arranged in a linear array. The through holes on the receiving plate have a key dual beneficial effect: First, during the pulse jet cleaning stage, the airflow can pass through the through holes and carry away the dust on the lower surface of the receiving plate, ensuring that there are no dead corners in the cleaning; Second, during the negative pressure suction stage, the through holes form an airflow channel from top to bottom, which greatly enhances the negative pressure environment inside the box, allowing dust and light debris to be more effectively sucked into the groove, significantly improving the dust collection efficiency.

[0011] Preferably, the upper part of the box has a wide opening design, and the area above the box is the material cutting area. The wide opening design at the upper part of the box greatly increases the receiving area and the fault tolerance space, ensuring that no matter how scattered the scraps are during the cutting process, they can be effectively collected into the box, avoiding the problem of materials splashing out of the box, thereby ensuring the integrity of the collection and the cleanliness of the workshop.

[0012] Compared with existing technologies, the advantages of this utility model are: I. This utility model innovatively adopts a synergistic dust removal mechanism of "pulse jet blowing + negative pressure adsorption," achieving deep cleaning of scrap materials in a confined space and curbing dust pollution at its source. Traditional collection devices often only focus on the recovery of large scrap materials, neglecting the treatment of fine debris and dust mixed in, resulting in the need for subsequent manual cleaning or secondary pollution. This utility model, by setting a moving trough with nozzles under the receiving plate, and matching it with a pulse generator and a negative pressure system, constitutes a highly efficient self-cleaning unit. During operation, the pulse generator controls the nozzles to generate short, powerful intermittent airflows that penetrate the through holes in the receiving plate from bottom to top, accurately impacting and shaking off debris adhering to the gaps between scrap materials and the surface of the receiving plate. At the same time, the negative pressure machine integrated on the moving trough immediately starts, forming a stable negative pressure environment inside the box, and rapidly sucking the blown dust and debris into the collection trough through the grooves. This "blowing and sucking" process is completed within a nearly sealed chamber, leaving no room for dust to escape. This completely solves the problem of dust dispersion during the cleaning process, greatly improves the working environment, and enhances the purity of the recycled materials.

[0013] II. Based on the first beneficial effect, this utility model has optimized its structure to support convenient implementation of this function. The core lies in integrating complex components such as the negative pressure unit, collection tank, and pulse nozzle into a pull-out movable tank, forming an independent "debris removal module." Workers only need to periodically pull out the handle like a drawer to remove the entire module, empty the collected debris, or perform maintenance. The operation is extremely simple, requiring no contact with the main scrap material or disassembly of the main equipment. On the other hand, for the cleaned main scrap material, this utility model uses a linear motor to drive the receiving plate to tilt for unloading. Compared to traditional hydraulic or pneumatic methods, linear motors offer high transmission precision, stable control, and low noise. They can accurately control the tilt angle, ensuring that the material is discharged orderly and completely from the outlet, effectively avoiding jamming or splashing problems. This "modular cleaning + automated unloading" design frees workers from tedious and dirty labor. Simple periodic pulling and starting operations are all that's needed to complete the entire collection and recycling process, greatly improving work efficiency and reflecting a highly humanized and automated design concept.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0021] Example 1 Please see Figures 1-5 As shown, this embodiment is a PVC sheet cutting scrap collection and recycling device, including a box 1, a receiving plate 11, a moving groove 5 and a collection groove 16. The receiving plate 11 is rotatably installed at the lower end of the box 1. A discharge port 12 is opened on the surface of the box 1 on one side of the receiving plate 11. A linear motor 8 is provided at the lower end of the discharge port 12. A slot 7 is provided below the receiving plate 11. The moving groove 5 is inserted into the slot 7. The upper end of the moving groove 5 is provided with nozzles 13 arranged in a square array. Grooves 15 are opened between the nozzles 13. A collection groove 16 is inserted into one side of the moving groove 5. The collection groove 16 is connected to the groove 15. When using this device, the opening at the top of the housing 1 can be positioned at the discharge port 12 of the slitting device. After the material is slitted, the scraps fall into the housing 1 and are caught by the receiving plate 11. The negative pressure machine 4 inside the device is activated when the moving trough 5 is inserted into the housing 1, preventing dust or debris from being scattered. The nozzle 13 at the top of the moving trough 5, in conjunction with the pulse device, sprays gas intermittently from below the receiving plate 11 to blow out the debris remaining between the material scraps (but not outside the housing 1). After being blown out, the debris is immediately sucked into the groove 15 by the negative pressure and falls into the collection trough 16. The operator only needs to periodically remove the moving trough 5 and the collection trough 16 to clean the debris. Other scraps remaining on the top of the receiving plate 11 can be tilted under the drive of the linear motor 8 and then discharged from the discharge port 12. This device can conveniently collect the scraps after slitting PVC sheets, reduce debris and dust, and has high practicality.

[0022] Example 2 Please see Figures 1-5As shown, this embodiment, based on embodiment 1, further includes: brackets 2 fixed on both sides of the box 1, and a base 3 fixed at the lower end of the brackets 2. By setting the brackets 2 and the base 3, the stability and reliability of the entire device are enhanced, so that it can be placed firmly below the discharge port 12 of the slitting machine, avoiding displacement or tipping due to equipment vibration or operational impact, and ensuring the continuity and safety of the collection process.

[0023] A negative pressure unit 4 is installed on one side of the collection tank 16. The outer shell of the negative pressure unit 4 is exposed on the outer wall of the moving tank 5. A handle 6 is installed on one side of the moving tank 5. The negative pressure unit 4 is connected to the collection tank 16. Integrating the negative pressure unit 4 into the outer wall of the moving tank 5 creates an efficient negative pressure air duct design, which allows the generated negative pressure suction to act on the groove 15 area with the shortest path and the highest efficiency, greatly improving the dust collection effect. The handle 6 makes it easy for workers to pull out the entire moving debris removal module (including the moving tank 5, the collection tank 16 and the negative pressure unit 4), realizing the modularization and convenience of the debris collection function, and facilitating regular cleaning and maintenance.

[0024] A pulse generator 14 is fixed to one side of the nozzle 13. The pulse generator 14 works with the rear controller to control each nozzle 13 to spray pulsed airflow. The pulse generator 14 controls the nozzle 13 to spray intermittent, high-intensity pulsed airflow instead of continuous blowing. This design has significant advantages: First, it achieves the best dust removal effect with the least amount of air. The strong airflow impact can effectively shake off tightly attached debris. Second, it avoids dust flying disorderly in the housing 1 due to continuous airflow. The short interval of waiting for negative pressure suction ensures that dust is controllable, improves cleaning efficiency and reduces energy consumption.

[0025] A rotating plate 9 is rotatably mounted at the lower end of the discharge port 12. A linear motor 8 is embedded in the middle of the rotating plate 9. The upper end of the linear motor 8 has an output end 10, which is rotatably connected to the lower surface of the receiving plate 11. This structural design provides a stable and powerful drive solution. By pushing a specific point on the lower surface of the receiving plate 11, the linear motor 8 can lift the receiving plate 11 with precise and controllable force and angle, making it tilt smoothly. This solves the problems of large impact and low precision that may exist in traditional cylinder or hydraulic rod drives, ensuring that scrap materials can slide out of the discharge port 12 smoothly and evenly, preventing blockage at the outlet.

[0026] The surface of the receiving plate 11 has through holes arranged in a linear array. The through holes on the receiving plate 11 have two key benefits: First, during the pulse jet cleaning stage, the airflow can pass through the through holes and carry away the dust on the lower surface of the receiving plate 11, ensuring that there are no dead corners in the cleaning; Second, during the negative pressure suction stage, the through holes form an airflow channel from top to bottom, which greatly enhances the negative pressure environment inside the box 1, so that dust and light debris can be more effectively sucked into the groove 15, greatly improving the dust collection efficiency.

[0027] The upper part of the box 1 has a wide opening design. The area above the box 1 is the material cutting area. The wide opening design at the upper part of the box 1 greatly increases the receiving area and the fault tolerance space, ensuring that no matter how scattered the scraps are during the cutting process, they can be effectively collected into the box 1, avoiding the problem of materials splashing out of the box, thereby ensuring the integrity of the collection and the cleanliness of the workshop.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
