Description

Technical Field

[0001] The invention relates to the technical field of plastic waste recycling, in particular to a processing device capable of recycling plastic waste. Background Art

[0002] Plastic is a material mainly composed of carbon, oxygen, hydrogen, nitrogen and other organic or inorganic elements. During the manufacturing process, plastic is a molten liquid that can be melted by heating, made to flow by applying pressure, and solidified by cooling to form various shapes. With the widespread use of plastic products, a large amount of plastic waste is also generated. The accumulation of plastic waste in the environment may cause pollution and damage to biodiversity. Therefore, when using and handling plastic products, attention should be paid to the principles of environmental protection and sustainable development, and resource waste and environmental pressure can be reduced by recycling and reusing plastic materials.

[0003] Among them, plastic sheets may be cut into different shapes on the initial sheets during processing according to different actual usage requirements, so some irregularly shaped sheet waste may be generated. Plastic sheet waste also needs to go through multiple steps when recycling, such as cleaning, crushing, granulation, etc., and when crushing and feeding, if a large amount of waste is directly put into the crusher, the feed port of the crusher is limited in size, and waste of different shapes and sizes may be stuck at the feed port, making it impossible for the waste to fall normally. If not handled in time, the amount of waste stuck in the feed port of the crusher may gradually increase, resulting in small-sized waste also unable to fall normally, resulting in the crusher being unable to complete the crushing work normally, affecting the crushing efficiency, and if the feed particle size is too large, it may also affect the discharge particle size, resulting in poor crushing effect.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Example: Figure 1-Figure 8As shown, a processing device for recyclable plastic waste described in 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, and a conveying mechanism 6 is arranged at the end of the frame 1 away from the crushing box 5, and the conveying mechanism 6 includes a group of rollers 61 rotatably connected to the side wall of the frame 1, and a limit block 3 is arranged on the top of the roller 61. The inner side wall of the end of the frame 1 away from the crushing box 5 is symmetrically inclined, and an auxiliary mechanism 7 is arranged on the top of the conveying mechanism 6. A transmission mechanism 8 is arranged between the conveying mechanism 6 and the auxiliary mechanism 7, and a cutting mechanism 9 is arranged on 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 roller 6 1 rotates to transport the plastic sheet waste toward the crushing box 5, and during the transportation process, the material is flattened and gradually brought together under the action of the inclined surface of the frame 1, so as to avoid failure at the auxiliary mechanism 7; the auxiliary mechanism 7 is equipped so that under the drive of the transmission mechanism 8, the pressure roller 71 located on the top of the roller 61 rotates synchronously and cooperates with it, clamps the sheet waste, and gradually approaches it to the cutting mechanism 9, so as to avoid the movement of the waste during cutting; the cutting mechanism 9 is equipped so that under the cooperation of the conveying mechanism 6 and the auxiliary mechanism 7, the first cutting component 91 and the second cutting component 92 perform preliminary cutting on the plastic sheet waste, cut it into smaller sizes and then drop it into the crushing box 5, so as to ensure the crushing effect of the crushing box 5.

[0035] In this embodiment, the plastic sheet waste is placed on the rollers 61, and under the action of the conveying mechanism 6, multiple rollers 61 rotate synchronously to transport the waste toward the crushing box 5. During the transportation process, the waste gradually gathers toward the center under the action of the inclined surface of the frame 1, and when it reaches below the limit block 3, the inclined surface of the limit block 3 intercepts the waste stacked on top to prevent more than a single layer of sheet materials from passing through and entering the straight section of the conveying mechanism 6. The rollers 61 and the pressure rollers 71 rotate in opposite directions. The pressure rollers 71 are lifted up by the sheet materials transported to the bottom during rotation. During this process, the pressure rollers 71 keep rotating, and the rollers 61 and the fixing nails 62 on the pressure rollers 71 hold the sheet materials The material is clamped and approaches the cutting mechanism 9. The first cutting component 91 performs the first cutting on the waste sheet material. When the conveying mechanism 6 is in a stationary state during intermittent conveying, the reciprocating screw rod 921 rotates, so that the movable blocks 922 located at both ends of the reciprocating screw rod 921 approach each other at the same time, and move away from each other when reaching the center of the reciprocating screw rod 921, and the sheet material cut by the first cutting component 91 is cut for the second time. The cutting directions of the first cutting component 91 and the second cutting component 92 are horizontal cutting and vertical cutting respectively, so that the waste sheet material is cut into smaller pieces, which fall into the crushing box 5 through the guide bucket 4 and are crushed by the crushing roller 51.

[0036] like Figure 1-Figure 6As shown, the conveying mechanism 6 also includes a fixing nail 62 fixedly connected to the outer wall of the roller 61, one end of each roller 61 is fixedly connected to the first synchronous wheel 63, and a first synchronous belt 64 is arranged between every two adjacent rollers 61, and the first synchronous belt 64 is staggered; the auxiliary mechanism 7 also includes an arc groove 72 opened on both sides of the frame 1, and the two ends of the pressure roller 71 pass through the arc groove 72 and are movably connected to the arc groove 72, and the arc groove 72 takes the roller 61 closest to the crushing box 5 as the center of the circle; the transmission mechanism 8 includes a first gear 82 fixedly connected to the end of the roller 61 closest to the crushing box 5, and the frame 1 A driving motor is fixedly installed on the side wall, and a non-full gear 81 is fixedly connected to the driving shaft of the driving motor, and the non-full gear 81 cooperates with the first gear 82. Both ends of the pressure roller 71 and one end of the rotating roller 61 closest to the crushing box 5 are fixedly connected with a second synchronous wheel 83, and a second synchronous belt 84 is connected between the pressure roller 71 and the rotating roller 61 closest to the crushing box 5; one end of the fixed shaft 911 and one end of the two crushing rollers 51 are fixedly connected with the second synchronous wheel 83, a second synchronous belt 84 is connected between the fixed shaft 911 and one of the crushing rollers 51, and a second synchronous belt 84 is connected between the two crushing rollers 51.

[0037] In this embodiment, the plastic sheet waste to be processed is placed on the roller 61, and the driving motor makes the non-full gear 81 drive the first gear 82 to rotate intermittently, and cooperates with the first synchronous wheel 63 and the first synchronous belt 64 on the roller 61 to make each roller 61 rotate synchronously, driving the waste to move toward the cutting mechanism 9. When the teeth of the non-full gear 81 are engaged with the first gear 82, the first gear 82 is driven to rotate. The first gear 82 drives the pressure roller 71 to rotate under the action of the second synchronous wheel 83 and the second synchronous belt 84. When the teeth of the non-full gear 81 are separated from the first gear 82, the first gear 82 and the pressure roller 71 stop rotating. During the movement of the material, the waste material is affected by the inclined surface of the inner wall of the frame 1 and gradually approaches the middle. 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 pins 62 on the surface of the pressure roller 71 contact the waste material during the rotation, so that the pressure roller 71 moves upward during the rotation, and the two ends of the pressure roller 71 slide in the arc groove 72. During this process, the pressure roller 71 always keeps rotating synchronously with the rotating roller 61. The pressure roller 71 cooperates with the rotating roller 61 below to clamp the waste material. The intermittent conveying makes the waste material gradually approach the first cutting component 91. When contacting the first cutting component 91, the rotating first saw blade 912 cuts the waste material.

[0038] like Figure 1-Figure 4As shown, a top plate 2 is fixedly connected to the top of the frame 1, a limit block 3 is fixedly connected to the bottom of the top plate 2, a side of the limit block 3 away from the crushing box 5 is arranged 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 assembly 92, a group of crushing rollers 51 are installed in 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 straight part of the frame 1, and 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 straight part of the frame 1.

[0039] In this embodiment, the distance between the bottom of the limit block 3 and the roller 61 is less than the thickness of the stacked waste of two plates. When the waste reaches the bottom of the limit block 3 on the roller 61, the inclined surface of the limit block 3 blocks the stacked waste. The waste at the bottom continues to move toward the cutting mechanism 9 under the action of the roller 61, while the waste at the top is blocked in place by the limit block 3 until it is flattened on the roller 61. The range of movement of the two ends of the pressure roller 71 in the arc groove 72 is limited, so the thickness of the waste 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 transport it to the first saw blade 912, the multiple fixing nails 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 temporary stop of the rotating roller 61, the reciprocating screw rod 921 rotates, driving the rotating second saw blade 925 to move, and the waste is cut again. The small-sized waste that falls enters the crushing box 5 through the guide bucket 4 under the cutting mechanism 9 and is crushed by the crushing roller 51.

[0040] like Figure 3-Figure 8 As shown, the first cutting assembly 91 includes a fixed shaft 911 rotatably connected to the side wall of the frame 1, a group 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 close to the crushing box 5, and 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 rod 921 arranged at the bottom of the fixed shaft 911, one end of the reciprocating screw rod 921 is connected to a stepping motor, a stopper 926 is fixedly connected to the middle of the reciprocating screw rod 921, and both ends of the reciprocating screw rod 921 are rotatably connected to the side wall of the frame 1. The reciprocating screw rod 921 rotates and passes through a group of movable blocks 922. The movable blocks 922 cooperate with the reciprocating screw rod 921. A limiting groove 923 is provided on the upper end of the movable block 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 rod 921. The arc plate 924 passes through the limiting groove 923 and is slidably connected to the limiting groove 923. A second saw blade 925 is installed on the top of the movable block 922, and 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, and 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 motor of the crushing roller 51 to cut the approaching waste. If one side of the approaching waste is parallel or nearly parallel to the fixed shaft 911, the bottom parts of multiple first saw blades 912 cut it when it is close, so a group of cutting lines will be cut on the waste, and some waste fragments may fall off. The width of the cutting line located in the center is greater than that of the other cutting lines. When the rotating roller 61 stops conveying, the stepping motor of the reciprocating screw rod 921 drives the two movable blocks 922 to move toward the midpoint at the same time, and return to reset at the same time when reaching the stop block 926. In this process, the top part of the rotating second saw blade 925 performs a secondary cutting on the waste, and the two second saw blades 925 simultaneously reach the widest cutting line cut by the first saw blade 912 At this time, the two second saw blades 925 do not contact each other, and the waste is completely cut from one side to the other. When the second saw blade 925 is reset, the movable block 922 stops moving, the roller 61 and the pressure roller 71 rotate again, and continue to transport the waste to the first saw blade 912. The roller 61 and the reciprocating screw rod 921 are in staggered motion. When the roller 61 rotates, the reciprocating screw rod 921 stops. When the roller 61 stops, the reciprocating screw rod 921 rotates. The cutting line of the first saw blade 912 and the second saw blade 925 is vertical. 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 is cut by the first saw blade 912, some fragments will fall into the crushing box 5. If it still does not fall, it will be cut again by the second saw blade 925 until it falls into the crushing box 5.

[0042] Working principle: When in use, start all motors of the equipment, place the plastic sheet waste to be processed on the roller 61, and the waste moves toward the crushing box 5 under the rotation of the roller 61. In the process of moving the waste, the waste is against the inclined surface of the frame 1, so that the waste is forced to move toward the middle, and the waste is prevented from stacking under the action of the limit block 3. When the waste contacts the pressure roller 71, the pressure roller 71 rotates with the roller 61 closest to the crushing box 5 as the center, and slides upward in the arc groove 72, and cooperates with the 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 roller 61, and approaches the rotating first saw blade 912. The waste contacts the first saw blade 912 The first saw blade 912 continues to cut, and the second saw blade 925 cooperates with the second saw blade 925 to cut the waste material until the waste material is cut into smaller pieces and falls into the crushing box 5, and is crushed into the required particle size by the crushing roller 51, and is discharged from the bottom of the crushing box 5.

[0043] The above shows and describes 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.
