Description

Technical Field

[0001] This invention relates to the field of plastic waste recycling technology, specifically to a processing device for recycling plastic waste. Background Technology

[0002] Plastic is a material primarily composed of carbon, oxygen, hydrogen, nitrogen, and other organic or inorganic elements. During manufacturing, plastic is a molten liquid that can be melted by heating, made to flow by applying pressure, and solidified by cooling, thus forming various shapes. With the widespread use of plastic products, a large amount of plastic waste is generated. The accumulation of plastic waste in the environment can lead to pollution and biodiversity loss. Therefore, when using and disposing of plastic products, the principles of environmental protection and sustainable development should be followed, and plastic materials should be recycled and reused to reduce resource waste and environmental pressure.

[0003] Depending on the actual usage requirements, plastic sheets may be cut into different shapes during processing, resulting in irregularly shaped waste sheets. Recycling this waste requires multiple steps, such as washing, crushing, and granulation. However, if a large amount of waste is directly fed into the crusher, the limited feed opening can cause different shapes and sizes of waste to become stuck, preventing it from falling out properly. If not addressed promptly, the amount of waste stuck in the feed opening may gradually increase, even preventing smaller pieces from falling out, thus hindering the crusher's crushing efficiency. Furthermore, excessively large feed particles can also affect the output particle size, leading to poor crushing results.

[0004] Therefore, the present invention provides a processing device for recyclable plastic waste. Summary of the Invention

[0008] The auxiliary mechanism is assembled so that the pressure roller located on top of the rotating roller rotates synchronously and cooperates with it under the drive of the transmission mechanism to clamp the waste material of the sheet and gradually move it closer to the cutting mechanism to prevent the waste material from moving during cutting.

[0009] The cutting mechanism, in conjunction with the conveying mechanism and auxiliary mechanism, involves the first and second cutting components to perform preliminary cutting of the plastic sheet waste into smaller sizes before it falls into the crushing box, ensuring the crushing effect of the crushing box.

[0011] Preferably, the auxiliary mechanism further includes arc-shaped grooves on both sides of the frame, with the two ends of the pressure roller passing through the arc-shaped grooves and movably connected to them, the arc-shaped grooves having the roller closest to the crushing box as the center.

[0012] Preferably, the transmission mechanism includes a first gear fixedly connected to the end of the roller closest to the crushing box, a drive motor fixedly installed on the side wall of the frame, a non-full gear fixedly connected to the drive shaft of the drive motor, the non-full gear cooperating with the first gear, a second synchronous pulley fixedly connected to both ends of the pressure roller and one end of the roller closest to the crushing box, and a second synchronous belt connected between the pressure roller and the roller closest to the crushing box.

[0013] Preferably, the first cutting assembly includes a fixed shaft rotatably connected to the side wall of the frame, and a set of first saw blades are fixedly connected to the outer wall of the fixed shaft. The fixed shaft is located on the side of the pressure roller near the crushing box, and the first saw blade located in the middle of the fixed shaft is thicker than the other first saw blades.

[0014] Preferably, the second cutting assembly includes a reciprocating lead screw disposed at the bottom of a fixed shaft. One end of the reciprocating lead screw is connected to a stepper motor, and a stop block is fixedly connected to the middle of the reciprocating lead screw. Both ends of the reciprocating lead screw are rotatably connected to the side wall of the frame. The reciprocating lead screw rotates through a set of movable blocks, which cooperate with the reciprocating lead screw. A limit groove is provided at the upper end of the movable block. An arc-shaped plate is fixedly connected to the inner wall of the frame. The arc-shaped plate is located at the top of the reciprocating lead screw and passes through the limit groove and is slidably connected to the limit groove. A second saw blade is installed on the top of the movable block, and the second saw blade is connected to a motor.

[0015] Preferably, the top height of the second saw blade is higher than the bottom height of the first saw blade, and the two movable blocks are symmetrically arranged and move in opposite directions.

[0016] Preferably, a top plate is fixedly connected to the top of the frame, a limiting block is fixedly connected to the bottom of the top plate, the side of the limiting block away from the crushing box is set as an inclined surface, a guide bucket is fixedly connected to the top of the crushing box, the guide bucket is located at the bottom of the second cutting component, and a set of crushing rollers is installed inside the crushing box, one of which is connected to a motor at one end.

[0018] Preferably, the density of fixing pins on the surface of the pressure roller is the same as the density of fixing pins on the surface of the roller where the frame is flat, and the density of fixing pins on the surface of the roller where the frame is inclined is less than the density of fixing pins on the surface of the roller where the frame is flat.

[0019] The beneficial effects of this invention are:

[0020] (1) The processing equipment for recyclable plastic waste described in this invention transports plastic sheet waste to the cutting mechanism via a conveying mechanism. Under the clamping of the conveying mechanism and the auxiliary mechanism, the sheet waste is intermittently brought closer to the first cutting component. Multiple fixing nails keep the sheet stable and prevent the waste from moving during cutting. Multiple first saw blades cut the sheet waste simultaneously. During the stationary period of the conveying mechanism, two second saw blades approach each other and reset simultaneously to perform secondary cutting on the sheet waste that has not fallen off, so that the waste is cut into a smaller size before entering the crushing box, which is beneficial to the operation of the crushing roller.

[0021] (2) The processing equipment for recyclable plastic waste described in this invention has an inclined surface on the inner wall of the frame, which causes the waste to gather in the middle during the conveying process, and avoids the stacking of the plates from affecting the pressure roller under the restriction of the limiting block, so that the plates can only pass the limiting block in a single layer.

[0022] (3) The processing equipment for recyclable plastic waste described in this invention uses an arc plate to limit the movement of two movable blocks, preventing the two movable blocks from rotating during movement. At the same time, the top of the arc surface of the arc plate can block the falling waste fragments, preventing the waste fragments generated during cutting from entering the groove of the reciprocating screw.

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] Example: Figures 1-8As shown, the processing equipment for recyclable plastic waste of the present invention includes a frame 1 and a crushing box 5. The crushing box 5 is fixedly connected to one end of the bottom of the frame 1. A conveying mechanism 6 is provided at the end of the frame 1 away from the crushing box 5. The conveying mechanism 6 includes a set of rotating rollers 61 rotatably connected to the side wall of the frame 1. A limit block 3 is provided at the top of the rotating rollers 61. The inner side wall of the end of the frame 1 away from the crushing box 5 is symmetrically inclined. An auxiliary mechanism 7 is provided at the top of the conveying mechanism 6. A transmission mechanism 8 is provided between the conveying mechanism 6 and the auxiliary mechanism 7. A cutting mechanism 9 is provided at the top of the crushing box 5. The cutting mechanism 9 includes a first cutting component 91 and a second cutting component 92. The conveying mechanism 6 is assembled to pass through the rotating rollers 61 and 62. The rotation of frame 1 transports the plastic waste towards the crushing box 5. During the transport process, the material is spread out and gradually brought together by the inclined surface of frame 1, preventing malfunctions at auxiliary mechanism 7. Auxiliary mechanism 7 is configured to be driven by transmission mechanism 8, with pressure roller 71 at the top of rotating roller 61 rotating synchronously and cooperating with it to clamp the plastic waste and gradually move it closer to cutting mechanism 9, preventing the waste from moving during cutting. Cutting mechanism 9 is configured to, with the cooperation of conveying mechanism 6 and auxiliary mechanism 7, perform preliminary cutting of plastic waste by first cutting component 91 and second cutting component 92, cutting it into smaller sizes before it falls into crushing box 5, ensuring the crushing effect of crushing box 5.

[0035] In this embodiment, waste plastic sheets are placed on rollers 61. Under the action of the conveying mechanism 6, multiple rollers 61 rotate synchronously, transporting the waste towards the crushing box 5. During the conveying process, the waste gradually gathers towards the center under the action of the inclined surface of the frame 1. When it reaches below the limit block 3, the inclined surface of the limit block 3 intercepts the waste stacked on top, preventing single-layer or higher sheets from passing through. It then enters the straight section of the conveying mechanism 6. The rollers 61 and pressure rollers 71 rotate in opposite directions. The pressure rollers 71 are lifted by the sheets below as they rotate. During this process, the pressure rollers 71 continue to rotate. The fixing nails 62 on the rollers 61 and pressure rollers 71 hold the sheets together. The material is clamped and moved closer to the cutting mechanism 9. The first cutting component 91 performs the first cut on the waste material. When the conveying mechanism 6 is in a stationary state during intermittent conveying, the reciprocating screw 921 rotates, causing the movable blocks 922 at both ends of the reciprocating screw 921 to move closer to each other and then move away from each other when they reach the center of the reciprocating screw 921. The material cut by the first cutting component 91 is then cut a second time. The cutting directions of the first cutting component 91 and the second cutting component 92 are transverse cutting and longitudinal cutting, respectively, so that the waste material is cut into smaller pieces. These pieces fall into the crushing box 5 through the guide bucket 4 and are crushed by the crushing roller 51.

[0036] like Figures 1-6As shown, the conveying mechanism 6 also includes fixing pins 62 fixedly connected to the outer wall of the rotating roller 61. A first synchronous pulley 63 is fixedly connected to one end of each rotating roller 61. A first synchronous belt 64 is provided between every two adjacent rotating rollers 61, and the first synchronous belts 64 are staggered. The auxiliary mechanism 7 also includes arc-shaped grooves 72 formed on both sides of the frame 1. The pressure roller 71 passes through the arc-shaped grooves 72 at both ends and is movably connected to the arc-shaped grooves 72. The arc-shaped grooves 72 are centered on the rotating roller 61 closest to the crushing box 5. The transmission mechanism 8 includes a first gear 82 fixedly connected to the end of the rotating roller 61 closest to the crushing box 5. The frame 1... A drive motor is fixedly installed on the side wall. The drive shaft of the drive motor is fixedly connected to a non-full gear 81. The non-full gear 81 cooperates with the first gear 82. The two ends of the pressure roller 71 and the end of the roller 61 closest to the crushing box 5 are all fixedly connected to the second synchronous pulley 83. The pressure roller 71 and the roller 61 closest to the crushing box 5 are connected by a second synchronous belt 84. One end of the fixed shaft 911 is fixedly connected to one end of each of the two crushing rollers 51. The fixed shaft 911 and one of the crushing rollers 51 are connected by a second synchronous belt 84. The two crushing rollers 51 are connected by a second synchronous belt 84.

[0037] In this embodiment, the plastic waste to be processed is placed on the rotating roller 61. The drive motor causes the non-full gear 81 to drive the first gear 82 to rotate intermittently. This, combined with the first synchronous pulley 63 and the first synchronous belt 64 on the rotating roller 61, causes each rotating roller 61 to rotate synchronously, moving the waste material towards the cutting mechanism 9. When the teeth of the non-full gear 81 mesh with the first gear 82, it drives the first gear 82 to rotate. The first gear 82, under the action of the second synchronous pulley 83 and the second synchronous belt 84, drives the pressure roller 71 to rotate. When the teeth of the non-full gear 81 disengage from the first gear 82, the first gear 82 and the pressure roller 71 stop rotating. During the material movement, the waste material gradually moves towards the center due to the inclination of the inner wall of the frame 1. The pressure roller 71 and the rotating roller 61 rotate in opposite directions. When the waste material reaches the bottom of the pressure roller 71, the fixing pin 62 on the surface of the pressure roller 71 contacts the waste material during the rotation, causing the pressure roller 71 to move upward during the rotation. The two ends of the pressure roller 71 slide in the arc groove 72. During this process, the pressure roller 71 always maintains synchronous rotation with the rotating roller 61. The pressure roller 71, together with the rotating roller 61 below, clamps the waste material. The intermittent conveying causes the waste material to gradually approach the first cutting component 91. When it contacts the first cutting component 91, the rotating first saw blade 912 cuts the waste material.

[0038] like Figures 1-4As shown, a top plate 2 is fixedly connected to the top of the frame 1, and a limiting block 3 is fixedly connected to the bottom of the top plate 2. The side of the limiting block 3 away from the crushing box 5 is set as an inclined surface. A guide bucket 4 is fixedly connected to the top of the crushing box 5. The guide bucket 4 is located at the bottom of the second cutting component 92. A set of crushing rollers 51 is installed inside the crushing box 5. One end of one of the crushing rollers 51 is connected to a motor. The density of the fixing nails 62 on the surface of the pressure roller 71 is the same as the density of the fixing nails 62 on the surface of the roller 61 at the flat part of the frame 1. The density of the fixing nails 62 on the surface of the roller 61 at the inclined part of the frame 1 is less than the density of the fixing nails 62 on the surface of the roller 61 at the flat part of the frame 1.

[0039] In this embodiment, the distance between the bottom of the limiting block 3 and the rotating roller 61 is less than the thickness of the two pieces of waste material stacked together. When the waste material reaches below the limiting block 3 on the rotating roller 61, the inclined surface of the limiting block 3 blocks the stacked waste material. The waste material at the bottom continues to move towards the cutting mechanism 9 under the action of the rotating roller 61, while the waste material at the top is blocked in place by the limiting block 3 until it is laid flat on the rotating roller 61. The range of movement of the two ends of the pressure roller 71 within the arc groove 72 is limited, thus the thickness of the waste material can be controlled. To prevent the waste from getting stuck at the pressure roller 71, when the pressure roller 71 and the rotating roller 61 clamp the waste and convey it to the first saw blade 912, the multiple fixing pins 62 on the pressure roller 71 and the rotating roller 61 can increase the friction on the waste, making the waste more stable. During the period when the rotating roller 61 is temporarily stopped, the reciprocating screw 921 rotates, driving the rotating second saw blade 925 to move and cut the waste again. The small-sized waste that falls off enters the crushing box 5 through the guide bucket 4 below the cutting mechanism 9 and is crushed by the crushing roller 51.

[0040] like Figures 3-8 As shown, the first cutting assembly 91 includes a fixed shaft 911 rotatably connected to the side wall of the frame 1. A set of first saw blades 912 are fixedly connected to the outer wall of the fixed shaft 911. The fixed shaft 911 is located on the side of the pressure roller 71 near the crushing box 5. The first saw blade 912 located in the middle of the fixed shaft 911 is thicker than the other first saw blades 912. The second cutting assembly 92 includes a reciprocating screw 921 disposed at the bottom of the fixed shaft 911. One end of the reciprocating screw 921 is connected to a stepper motor. A stop block 926 is fixedly connected to the middle of the reciprocating screw 921. Both ends of the reciprocating screw 921 are rotatably connected to the side wall of the frame 1. A reciprocating screw 921 rotates through a set of movable blocks 922. The movable blocks 922 cooperate with the reciprocating screw 921. A limit groove 923 is opened at the upper end of the movable blocks 922. An arc plate 924 is fixedly connected to the inner wall of the frame 1. The arc plate 924 is located at the top of the reciprocating screw 921. The arc plate 924 passes through the limit groove 923 and is slidably connected to the limit groove 923. A second saw blade 925 is installed on the top of the movable blocks 922. The second saw blade 925 is connected to a motor. The top height of the second saw blade 925 is higher than the bottom height of the first saw blade 912. The two movable blocks 922 are symmetrically arranged and move in opposite directions.

[0041] In this embodiment, the first saw blade 912 rotates under the drive of the crushing roller 51 motor, cutting the nearby waste material. If one side of the nearby waste material is parallel or nearly parallel to the fixed shaft 911, the bottom parts of multiple first saw blades 912 will cut it when it gets close, thus creating a set of cutting lines on the waste material. Some waste material fragments may fall off. The width of the cutting line located at the center is greater than that of the other cutting lines. When the rotating roller 61 stops conveying, the stepper motor of the reciprocating screw 921 drives two movable blocks 922 to move simultaneously towards the center point. When they reach the stop block 926, they return to their original positions simultaneously. During this process, the top part of the rotating second saw blade 925 performs a secondary cut on the waste material. The two second saw blades 925 simultaneously reach the widest cutting line cut by the first saw blade 912. At this point, the two second saw blades 925 are not in contact with each other, and the waste material has been completely cut from one side to the other. When the second saw blade 925 returns to its original position, the movable block 922 stops moving, and the rotating roller 61 and the pressure roller 71 rotate again to continue conveying the waste material to the first saw blade 912. The rotating roller 61 and the reciprocating screw 921 move alternately. When the rotating roller 61 rotates, the reciprocating screw 921 stops. When the rotating roller 61 stops, the reciprocating screw 921 rotates. The cutting lines of the first saw blade 912 and the second saw blade 925 are perpendicular. The second saw blade 925 is located on the side of the first saw blade 912 away from the pressure roller 71. After the waste material is cut by the first saw blade 912, some fragments will fall into the crushing box 5. If they do not fall, they will be cut again by the second saw blade 925 until they fall into the crushing box 5.

[0042] Working principle: During use, start all motors of the equipment and place the plastic waste to be processed onto the rotating roller 61. As the rotating roller 61 rotates, the waste moves towards the crushing box 5. During the movement of the waste, it abuts against the inclined surface of the frame 1, causing the waste to move towards the center. Under the action of the limit block 3, the waste is prevented from piling up. When the waste comes into contact with the pressure roller 71, the pressure roller 71 slides upward in the arc groove 72 with the rotating roller 61 closest to the crushing box 5 as the center. It works with the rotating roller 61 at the bottom of the waste to clamp the waste. The waste is clamped and moved by the rotating pressure roller 71 and the rotating roller 61, and moves closer to the rotating first saw blade 912. The waste comes into contact with the first saw blade 912. During this process, multiple rotating first saw blades 912 cut the waste material. The cutting time is affected by the degree of movement of the waste material. During this process, some of the cut fragments may fall and enter the crushing box 5 through the guide bucket 4. When the rotating roller 61 temporarily stops rotating, the two rotating second saw blades 925 simultaneously move towards the center of the reciprocating screw 921 to cut the waste material a second time. The waste material that does not fall continues to be held and conveyed by the pressure roller 71 and the rotating roller 61. The first saw blades 912 continue to cut, while cooperating with the second saw blades 925 to cut, until the plastic sheet waste is cut into smaller fragments that fall into the crushing box 5. The crushing roller 51 then crushes it into the required particle size and discharges it from the bottom of the crushing box 5.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by the present invention. The scope of protection of the present invention is defined by the appended claims and their equivalents.
