Description

Technical Field

[0001] This invention belongs to the field of plastic recycling technology, and more specifically, relates to a waste plastic recycling device for plastic printing and die cutting. Background Technology

[0002] A plastic workpiece printing and processing machine is a specialized piece of equipment used for processing plastic workpieces. It integrates two main functions: printing and processing. It can print patterns, text, etc. on the surface of plastic workpieces, and can process hollow board boxes according to pre-designed shapes and sizes. Waste is generated after processing, so a waste removal device is usually installed to collect the waste.

[0003] The Chinese patent publication number is CN209886249U, which describes a waste removal device for a plastic hollow board box printing and die-cutting machine. This utility model has a simple and reasonable mechanism and can effectively remove the processing waste that has been cut off from the plastic hollow board without the need for manual removal, saving time and effort.

[0004] Existing machine tool waste recycling devices have the following disadvantages:

[0005] 1. Existing equipment for plastic scrap recycling often lacks a guiding mechanism at the discharge port. After the processing equipment processes the plastic, the plastic scraps generated may be scattered into the surrounding environment due to airflow, static electricity, or their own irregular movement. During the later recycling process, manual collection and cleaning of the scattered plastic scraps is required, which is labor-intensive and may generate dust, affecting the production environment.

[0006] 2. Some existing waste recycling equipment is equipped with guiding mechanisms, but plastic debris generated during the processing of plastic workpieces is prone to static electricity due to friction. When the statically charged plastic debris approaches the guide plate or the inner wall of the pipe, the electrostatic adsorption may cause the plastic debris to stick to it, requiring manual cleaning afterwards, which affects the recycling efficiency.

[0007] In view of this, we have studied and improved the existing structure and its shortcomings, and provided a waste plastic recycling device for plastic printing and die cutting, in order to achieve a more practical purpose. Summary of the Invention

[0008] To address the aforementioned technical problems, this invention provides a waste plastic recycling device for plastic printing and die-cutting, thereby resolving the problems described above.

[0009] A waste plastic recycling device for plastic printing and die-cutting includes a processing device and a processing support. The processing device is fixedly mounted on the processing support. The processing device is equipped with a guiding mechanism for guiding plastic debris and a collection mechanism for collecting the plastic debris. The guiding mechanism includes a guide tube, a servo motor, a return rod, and a reciprocating lead screw. The collection mechanism includes a dust collection box and a waste bin. The waste bin is slidably mounted on the inner wall of the dust collection box. Two telescopic adjustment mechanisms are fixedly installed between the guide tube and the dust collection box. A fixed rod is fixedly installed between the servo motor and the guide tube. The loop rod is located on the inner wall of the guide tube. A threaded groove is opened through the upper end of the loop rod. The reciprocating lead screw is threadedly installed on the inner wall of the threaded groove. A discharge plate is provided at the lower end of the processing equipment. The dust collection box is located between two processing supports. At least two sliding grooves are opened at the upper end of the dust collection box. Two mounting tubes are provided at both ends of the waste box. Each mounting tube is slidably installed on the inner wall of the sliding groove. A fixed rod is installed on the inner wall of the waste box. A screen is provided. A first arc-shaped block is fixedly installed at the upper end of the waste bin. The end of the first arc-shaped block is arc-shaped. A rubber buffer pad is fixedly installed at the upper end of the first arc-shaped block. L-shaped sliding rods are fixedly installed at both ends of the waste bin. Each L-shaped sliding rod is slidably installed on the inner wall of each mounting tube. A first spring and a first telescopic rod are fixedly installed between each L-shaped sliding rod and the mounting tube. Each first telescopic rod is located on the inner wall of the first spring. Positioning plates are fixedly installed at both ends of the inner wall of the guide tube. Two guide rods are fixedly installed at the lower end of each positioning plate. A rotating shaft is fixedly installed at the output end of the servo motor. A first gear is fixedly installed at the circumferential end of the rotating shaft. Two push rods are also fixedly installed at the circumferential end of the rotating shaft. The ends of the two push rods are arc-shaped. At least two guide grooves are opened through the upper end of the U-shaped rod. The U-shaped rod is slidably installed on each guide rod through the guide grooves. Cleaning brushes are provided at the four ends of the U-shaped rod. A second spring and a second telescopic rod are fixedly installed between each cleaning brush and the U-shaped rod.

[0010] Preferably, a mounting component is fixedly installed at the lower end of the guide tube, and the reciprocating screw is rotatably mounted on the mounting component.

[0011] Preferably, a second gear is fixedly installed at the circumferential end of the reciprocating lead screw, and a transmission toothed belt is meshed between the second gear and the first gear.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, a guide pipe is installed below the discharge plate. After the processing equipment processes the plastic workpiece, the plastic debris generated may be scattered into the surrounding environment due to airflow, static electricity, or its own irregular movement. This device, by setting up a guide pipe, can constrain the movement path of the waste material, ensuring that the waste material falls accurately into the waste bin, avoiding the possibility of dust and debris scattering in the production workshop, and eliminating the need for users to frequently clean up the waste material around the equipment, thus saving manpower.

[0014] In this invention, by setting a telescopic adjustment rod and a guide tube in combination, the position of the guide tube can be adjusted. The height of the discharge plate on different models of processing equipment may be different. The height-adjustable guide tube allows it to flexibly cooperate with various processing equipment, ensuring that the waste material can fall smoothly from the discharge plate through the guide tube into the waste box. It has high flexibility and good adaptability.

[0015] In this invention, a U-shaped rod and a cleaning brush are used in conjunction. The U-shaped rod drives the cleaning brush to move up and down repeatedly to clean the plastic debris adsorbed in the guide tube. This promptly removes the electrostatically adsorbed plastic debris, preventing it from accumulating in the guide tube and keeping the guide plate clean. This ensures that the waste can smoothly fall into the waste bin through the guide tube, preventing the accumulation of plastic debris from affecting waste recycling and avoiding problems such as missed recycling.

[0016] In this invention, by combining a waste bin with a screen, fine plastic fragments and larger plastic workpiece waste can be separated and collected through the screen, facilitating different processing of the waste later. For larger plastic workpiece waste, the recycling process may focus more on physical processing, such as crushing and pulping, while the recycling of fine plastic fragments and dust may involve chemical processing or fine processing. The screen is designed to employ more precise recycling processes for different types of waste, thereby improving recycling efficiency.

[0017] In this invention, by setting up a first arc-shaped block, a rubber buffer pad, a first spring, and a first telescopic rod in cooperation, the sliding groove moves up and down by rotating the push rod, and the waste bin vibrates by rebounding the first spring. This achieves efficient separation of small plastic fragments and larger plastic workpiece waste. The waste bin drives the screen to vibrate, which keeps the waste in a state of continuous movement, effectively preventing the waste from clogging the screen holes. At the same time, it can also speed up the speed at which the waste passes through the screen holes, improve the overall screening efficiency, shorten the screening time, and make the recycling process more efficient.

Detailed Implementation

[0028] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0029] Please see Figure 1 - Figure 9This invention provides a waste plastic recycling device for plastic printing and die-cutting, including a processing device 1 and a processing support 11. The processing device 1 is fixedly mounted on the processing support 11. The processing device 1 is equipped with a guiding mechanism for guiding plastic debris and a collection mechanism for collecting plastic debris. The guiding mechanism includes a guide tube 4, a servo motor 5, a return rod 6, and a reciprocating screw 7. The collection mechanism includes a dust collection box 2 and a waste bin 3. The waste bin 3 is slidably mounted on the inner wall of the dust collection box 2. Two telescopic adjustment rods 45 are fixedly installed between the guide tube 4 and the dust collection box 2. A fixing rod 51 is fixedly installed between the servo motor 5 and the guide tube 4. The return rod 6 is located on the inner wall of the guide tube 4. A thread groove 62 is opened through the upper end of the return rod 6. The reciprocating screw 7 is threaded. The material is mounted on the inner wall of the wire groove 62. The lower end of the processing equipment 1 is provided with a discharge plate 12. The dust collection box 2 is located between two processing supports 11. When processing plastic workpieces, the user places the plastic workpieces to be processed on the feeding platform and feeds them into the processing equipment 1 through a feeding device such as a conveyor belt or rollers. The processing equipment 1 is equipped with a positioning system. After the plastic workpiece is positioned, the processing tool in the processing equipment 1 starts to work. The tool holder is driven by a hydraulic system or a motor, which drives the processing tool to press down quickly and powerfully. After processing, plastic debris and plastic workpiece waste will be generated and discharged from the discharge plate 12. The processed plastic workpiece is transported to the output end of the machine through a conveyor belt. A collection mechanism is usually provided at the lower end of the discharge plate 12 to collect the plastic debris.

[0030] The upper end of the dust collection box 2 is provided with at least two sliding grooves 21. Two mounting tubes 36 are provided on both sides of the waste bin 3. Each mounting tube 36 is slidably mounted on the inner wall of the sliding groove 21. A screen 37 is fixedly mounted on the inner wall of the waste bin 3. A first arc-shaped block 31 is fixedly mounted on the upper end of the waste bin 3. The end of the first arc-shaped block 31 is arc-shaped. A rubber buffer pad 32 is fixedly mounted on the upper end of the first arc-shaped block 31. L-shaped sliding rods 33 are fixedly mounted on both sides of the waste bin 3. Each L-shaped sliding rod 33 is slidably mounted on the inner wall of each mounting tube 36. A first spring 34 and a first telescopic rod 35 are fixedly mounted between each L-shaped sliding rod 33 and the mounting tube 36. Each first telescopic rod 35 is located on the inner wall of the first spring 34. When the rotating shaft 52 rotates, it simultaneously drives the push rod 54 to rotate. When the push rod 54 rotates, it contacts the rubber buffer pad 32. At time 2, the waste bin 3 will move downward through the rubber buffer pad 32 and the first arc block 31. The downward movement of the first arc block 31 will cause the waste bin 3 to move downward. The downward movement of the waste bin 3 will cause the L-shaped slide rod 33 to slide inside the mounting tube 36. When the push rod 54 rotates away from the edge of the first arc block 31, the first spring 34 will rebound and cause the waste bin 3 to move upward again, thereby realizing the vibration of the waste bin 3. When the waste bin 3 vibrates, it will pass through the screen 37 to screen and separate the finer plastic debris and dust and the larger plastic workpiece waste, which will facilitate subsequent recycling. When recycling waste, the user can pull the dust collection box 2 to move the waste bin 3 and the guide tube 4 away from the bottom of the discharge plate 12, and pull the mounting tube 36 to move the waste bin 3 away from the inner wall of the dust collection box 2. The waste and plastic debris in the waste bin 3 and the dust collection box 2 can be dumped and collected separately.

[0031] Positioning plates 41 are fixedly installed on both ends of the inner wall of the guide pipe 4. Two guide rods 42 are fixedly installed on the lower end of each positioning plate 41. When the device is in use, the dust collection box 2 can be moved directly below the discharge plate 12. The user can adjust the height of the guide pipe 4 by using the telescopic adjustment rod 45 so that the guide pipe 4 is moved to a height that matches the discharge plate 12. When the discharge plate 12 discharges waste, the guide pipe 4 can guide the plastic debris. The plastic debris can enter the waste box 3 along the guide pipe 4 for collection.

[0032] A rotating shaft 52 is fixedly installed at the output end of the servo motor 5. A first gear 53 is fixedly installed at the circumferential end of the rotating shaft 52. Two push rods 54 are also fixedly installed at the circumferential end of the rotating shaft 52. The ends of the two push rods 54 are arc-shaped. At least two guide grooves 61 are opened through the upper end of the loop rod 6. The loop rod 6 is slidably installed on each guide rod 42 through the guide grooves 61. Cleaning brushes 63 are provided on all four sides of the loop rod 6. A second spring 64 and a second telescopic rod 65 are fixedly installed between each cleaning brush 63 and the loop rod 6. An installation part 43 is fixedly installed at the lower end of the guide tube 4. When the guide tube 4 guides and collects plastic debris, the plastic debris waste generated during the processing of plastic workpieces is easily generated by friction. When static electricity is generated, and plastic debris carrying static electricity approaches the inner wall of the guide tube 4, the electrostatic attraction may cause the plastic debris to adhere to it. The user can start the servo motor 5. The start of the servo motor 5 will drive the rotating shaft 52 to rotate. The rotation of the rotating shaft 52 will drive the first gear 53 to rotate. The rotation of the first gear 53 will drive the second gear 71 to rotate through the transmission belt 72. The rotation of the second gear 71 will drive the reciprocating screw 7 to rotate. The rotation of the reciprocating screw 7 will drive the loop rod 6 to move up and down reciprocally. The movement of the loop rod 6 will drive the cleaning brush 63 to move up and down reciprocally through each second telescopic rod 65 and the second spring 64. When the cleaning brush 63 moves and scrapes the inner wall of the guide tube 4, it will clean the plastic debris adsorbed on the guide tube 4.

[0033] The reciprocating lead screw 7 is rotatably mounted on the mounting part 43. A second gear 71 is fixedly mounted on the circumferential end of the reciprocating lead screw 7. A transmission toothed belt 72 is meshed between the second gear 71 and the first gear 53.

[0034] Working principle:

[0035] In the first step, when processing plastic workpieces, the user places the workpieces to be processed on the feeding platform and feeds them into the processing equipment 1 through a feeding device such as a conveyor belt or rollers. The processing equipment 1 is equipped with a positioning system. After the plastic workpiece is positioned, the processing tool in the processing equipment 1 starts to work. The tool holder is driven by a hydraulic system or a motor, which drives the processing tool to press down quickly and powerfully. After processing, plastic debris and plastic workpiece waste will be generated and discharged from the discharge plate 12. The processed plastic workpiece is transported to the output end of the machine through a conveyor belt. A collection mechanism is usually provided at the lower end of the discharge plate 12 to collect the plastic debris.

[0036] The second step is that when this device is in use, the dust collection box 2 can be moved directly below the discharge plate 12. The user can adjust the height of the guide pipe 4 through the telescopic adjustment rod 45 so that the guide pipe 4 is moved to a height that matches the discharge plate 12. When the discharge plate 12 discharges waste, the guide pipe 4 can guide the plastic debris. The plastic debris can enter the waste box 3 along the guide pipe 4 for collection.

[0037] This device has a guide pipe 4 installed below the discharge plate 12. After the processing equipment 1 processes the plastic workpiece, the plastic debris generated may be scattered into the surrounding environment due to the airflow, static electricity or its own irregular movement. This device can constrain the movement path of the waste by setting the guide pipe 4, ensuring that the waste falls accurately into the waste bin 3, avoiding the possibility of dust and debris scattering in the production workshop, and eliminating the need for users to frequently clean up the waste around the equipment, thus saving manpower.

[0038] This device is equipped with a telescopic adjustment rod 45 and a guide tube 4, which allows the position of the guide tube 4 to be adjusted. The height of the discharge plate 12 on different models of processing equipment 1 may be different. The height-adjustable guide tube 4 allows it to flexibly cooperate with various processing equipment 1, ensuring that the waste material can fall smoothly from the discharge plate 12 through the guide tube 4 into the waste box 3. It has high flexibility and good adaptability.

[0039] Third, when the guide tube 4 guides and collects plastic debris, the plastic debris generated during the processing of plastic workpieces is easily static electricity due to friction. When the statically charged plastic debris approaches the inner wall of the guide tube 4, the electrostatic adsorption may cause the plastic debris to adhere to it. The user can start the servo motor 5. The start of the servo motor 5 will drive the rotating shaft 52 to rotate. The rotation of the rotating shaft 52 will drive the first gear 53 to rotate. The rotation of the first gear 53 will drive the second gear 71 to rotate through the transmission belt 72. The rotation of the second gear 71 will drive the reciprocating screw 7 to rotate. The rotation of the reciprocating screw 7 will drive the return rod 6 to move up and down reciprocally. The movement of the return rod 6 will drive the cleaning brush 63 to move up and down reciprocally through each second telescopic rod 65 and the second spring 64. When the cleaning brush 63 moves and scrapes the inner wall of the guide tube 4, it will clean the plastic debris adsorbed on the guide tube 4.

[0040] This device uses a rotary rod 6 and a cleaning brush 63 in combination. The rotary rod 6 drives the cleaning brush 63 to move up and down reciprocally to clean the plastic debris adsorbed in the guide tube 4. This removes the plastic debris attracted by electrostatic force in a timely manner, preventing the plastic debris from accumulating in the guide tube 4. This keeps the guide plate clean and ensures that the waste can fall smoothly into the waste bin 3 through the guide tube 4. The accumulation of plastic debris will not affect the recycling of waste and will avoid problems such as missed recycling.

[0041] Fourthly, when the rotating shaft 52 rotates, it simultaneously drives the push rod 54 to rotate. When the push rod 54 rotates and contacts the rubber buffer pad 32, it will drive the waste bin 3 to move downward through the rubber buffer pad 32 and the first arc-shaped block 31. The downward movement of the first arc-shaped block 31 will drive the waste bin 3 to move downward. The downward movement of the waste bin 3 will drive the L-shaped slide rod 33 to slide inside the mounting tube 36. When the push rod 54 rotates away from the edge of the first arc-shaped block 31, the first spring 34 will rebound and drive the waste bin 3 to move upward again. This causes the waste bin 3 to vibrate. When the waste bin 3 vibrates, it will pass through the screen 37 to separate the finer plastic fragments and dust and the larger plastic workpieces, making it easier for subsequent recycling. When recycling waste, the user can pull the dust collection box 2 to move the waste bin 3 and the guide pipe 4 away from the bottom of the discharge plate 12, and pull the installation pipe 36 to move the waste bin 3 away from the inner wall of the dust collection box 2. The waste and plastic fragments in the waste bin 3 and the dust collection box 2 can then be dumped and collected separately.

[0042] This device, by combining a waste bin 3 and a screen 37, can separate and collect fine plastic fragments and larger plastic workpiece waste through the screen 37, facilitating different processing of the waste later. For larger plastic workpiece waste, the recycling process may focus more on physical processing, such as crushing and pulping, while the recycling of fine plastic fragments and dust may involve chemical processing or fine processing. The screen 37 is designed to employ more precise recycling processes for different types of waste, thereby improving recycling efficiency.

[0043] This device, through the coordinated arrangement of a first arc-shaped block 31, a rubber buffer pad 32, a first spring 34, and a first telescopic rod 35, achieves efficient separation of fine plastic fragments and larger plastic workpiece waste by rotating a push rod 54 to move the sliding groove 21 up and down, and by rebounding the first spring 34 to vibrate the waste bin 3. The waste bin 3 drives the screen 37 to vibrate, keeping the waste in a state of continuous movement, effectively preventing the waste from clogging the screen holes, and also accelerating the speed at which the waste passes through the screen holes, thereby improving the overall screening efficiency, shortening the screening time, and making the recycling process more efficient.
