Description

Technical Field

[0001] The invention relates to the technical field of plastic processing equipment, in particular to a plastic processing crushing device and a crushing method thereof. Background Art

[0002] Plastic granules are widely used in the production of various building materials. Using plastic products as building materials can effectively prevent the influence of moisture, mold and other environmental factors. In addition, plastic granules are also used to make various plastic containers, such as plastic bottles. When crushing plastic granules, the whole piece of plastic is usually broken. When recycling plastics, the finished plastic products are also crushed into granules.

[0003] During the crushing process, the friction between the material and the crushing equipment will generate a lot of heat, and the plastic particles will melt when exposed to heat. This causes the plastic products to soften due to the high temperature. The softened plastic will stick to the crushing components. After long-term operation, the internal components will stick together, affecting the subsequent processing efficiency. To address the above problems, the following solutions are proposed. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a plastic processing pulverizing device, comprising a pulverizing and cooling mechanism, the pulverizing and cooling mechanism also comprises an outer case, a gear set is fixedly connected to the side wall of the outer case, two gears inside the gear set are meshed with each other, a rotating tube is rotatably connected to the side wall of the gear set, and one end of the rotating tube away from the gear set is connected to a water inlet tank through and through;

[0005] The drainage mechanism includes a fixed ring fixedly connected to the side wall of the outer chassis, a telescopic frame fixedly connected to the side wall of the fixed ring, and a limiting ring fixedly connected to one end of the telescopic frame away from the fixed ring;

[0006] The feeding mechanism comprises a feeding plate which is connected to the top of the outer chassis through the feeding plate, a folding frame is fixedly connected to the inner wall of the feeding plate, and a sliding frame is slidably connected to the inner wall of the feeding plate.

[0007] Preferably, the crushing and cooling mechanism also includes a motor fixedly connected to the top of the water inlet tank, the output shaft of the motor is fixedly connected to a driving gear, and the outer wall of the driving gear is meshingly connected to the outer wall of the gear set.

[0008] Preferably, the pulverizing and cooling mechanism also includes a pulverizing tube fixedly connected to a side of the gear group away from the rotating tube, a plurality of water inlet pipes are opened at the side wall of the pulverizing tube, a fan blade is fixedly connected to the inner wall of the gear group, a fixed plate is fixedly connected to the inner wall of the pulverizing tube, a hydraulic pipe is fixedly connected to the side wall of the fixed plate, a piston plate is slidably connected to the inner wall of the hydraulic pipe, a push rod is fixedly connected to the side wall of the piston plate, a pressure slide plate is fixedly connected to the end of the push rod away from the fixed plate, a pulling spring is fixedly connected to the bottom of the pressure slide plate, and a piston plate is arranged inside the device by utilizing the moving characteristics of the pressure slide plate. When moving, the piston plate will force the liquid inside the hydraulic pipe to enter the other end through the holes of the piston plate. In this process, due to the limitation of the holes of the piston plate, the liquid will provide a greater resistance to the piston plate when passing through the small holes, and the speed of the compressed slide plate moving outward will be slowed down simultaneously. When the compressed slide plate moves outward and forms a gap for water outlet with the crushing tube, the high pressure disappears, and the pulling spring pulls the compressed slide plate to reset. At this time, the piston plate provides another resistance to reduce the reset speed of the fixed plate. Through the application of the above components, the drainage time of the equipment is increased when draining water, which avoids the increase of the internal water source temperature and reduces the cooling effect of the equipment.

[0009] Preferably, the crushing and cooling mechanism also includes a driving gear fixedly connected to the inner wall of the water inlet pipe, and the end of the driving gear away from the crushing tube is fixedly connected to the cutting blade, and the side walls of several cooling boxes are connected with circulation pipes. When the equipment is used, the water inlet pipe is connected to the water inlet box, the material to be processed is placed inside the feed plate, and the power of the motor is turned on. At this time, the motor drives the fan blades to rotate rapidly through the gear set. At this time, the water inside the water inlet box enters the crushing tube through the drive of the fan blades, and the crushing tube also rotates synchronously at this time. The centrifugal force generated by the crushing tube will force the water entering the crushing tube to diffuse around, and the diffused water enters the cooling box through the water inlet pipe. When there is too much water in one of the cooling boxes, it enters the inner wall of the other cooling box through the circulation pipe, thereby realizing the cooling of the cutting blade. Through the application of the above-mentioned components, when the equipment is crushing, the internal water will cool the inner wall of the cutting blade, avoiding the high temperature generated inside the cutting blade after long-term work, causing the plastic particles inside the equipment to melt, and causing adhesion between the components and the plastic.

[0010] Preferably, the drainage mechanism also includes a plurality of L-shaped frames rotatably connected to the inner wall of the limiting ring, the ends of the plurality of L-shaped frames away from the limiting ring are fixedly connected to the side wall of the pressure slide, and a fixed plate is fixedly connected to the side wall of the limiting ring. The fixed plate is used to divide the interior of the crushing tube into a front and a rear part, so that when the equipment performs the above-mentioned water discharge, the water source at the end of the crushing tube close to the pressure slide will be preferentially discharged. Since there is a restriction of the fixed plate inside the crushing tube, when the equipment drains water, the water source at the end of the crushing tube close to the pressure slide will be discharged outward through the gap between the pressure slide and the crushing tube, while the water source at the other end of the crushing tube will enter the end of the crushing tube close to the pressure slide through the cooling box and the circulation pipe. Through the application of the above-mentioned components, it is avoided that the water inside the crushing tube is directly discharged outward through the gap between the pressure slide and the crushing tube, which affects the cooling effect of the cutting blade.

[0011] Preferably, the drainage mechanism also includes a pulling rod fixedly connected to the side wall of the fixing plate, a filter screen is fixedly connected to the inner wall of the outer chassis, a cleaning rack is fixedly connected to the outer wall of the pulling rod, a linkage rod is fixedly connected to the side wall of the pulling rod, and a collecting box is connected through the side wall of the outer chassis. When the above-mentioned cutting is performed, the material enters the processing area through the feeding plate, and will fall on the top of the filter screen after processing. At this time, two states will be presented. When the components that meet the size fall on the top of the filter screen, they will be stirred by the crushing and cooling mechanism and finally pass through the holes of the filter screen and fall out of the bottom of the outer chassis. The materials that do not meet the requirements will stay on the top of the filter screen and The cutting is carried out by the crushing and cooling mechanism until the material is crushed to the required size and passes through the filter. Through the application of the above components, the size of the particles after the material is crushed is guaranteed. In addition, taking advantage of the fact that the inside of the above-mentioned crushing tube is filled with water, a pressure slide is provided inside the equipment. When the fan blades continue to transport water to the inside of the crushing tube, the water pressure inside the crushing tube increases, and the high-pressure water will push the pressure slide to move outward along the inner wall of the crushing tube. In this process, the pressure slide drives the limiting ring to extend outward through the L-shaped frame, and the limiting ring slides along the bottom of the filter through the fixing plate, the pulling rod and the cleaning frame to remove impurities in the holes inside the filter.

[0012] Preferably, the feeding mechanism also includes a pushing square rod slidably connected to the inner wall of the sliding frame, the bottom of the pushing square rod is rotatably connected to the outer wall of the folding frame, the pushing square rod is fixedly connected to an end of the folding frame away from the folding frame with a fixed square plate, and the side wall of the pushing square rod is rotatably connected with a rotating square plate. Utilizing the characteristic of the regular movement of the above-mentioned pulling rod, a feeding mechanism is arranged inside the equipment. When the pulling rod moves, the linkage rod will be synchronously displaced. When the linkage rod is displaced, the linkage rod compresses the folding frame to bend. At this time, the sliding frame will be displaced left and right along the inner wall of the feeding plate, and the pushing square rod will move up and down along the inner wall of the sliding frame. When the pushing square rod moves up, the pushing square rod will be inserted into the plastic raw material, and the rotating square plate will be squeezed and move closer to the pushing square rod with the connection point as the center. When the pushing square rod moves down, the rotating square plate will be blocked by the material and will open to the surroundings. As the pushing square rod moves down, the internal material is forced to enter the outer chassis along the inside of the feeding plate. Through the application of the above-mentioned components, the equipment can effectively avoid material blockage inside the feeding plate during processing, thereby affecting the processing efficiency of the equipment.

[0013] A plastic processing crushing device and a crushing method thereof, comprising the following steps:

[0014] S1: When using the equipment, connect the water inlet pipe to the water inlet tank, place the material to be processed inside the feed plate, and turn on the power of the motor. At this time, the motor drives the fan blades to rotate rapidly through the gear set;

[0015] S2: The water in the water tank is driven by the fan blades to enter the grinding tube, and the grinding tube also rotates synchronously at this time. The centrifugal force generated by the grinding tube will force the water entering the grinding tube to spread around;

[0016] S3: The diffused water enters the interior of the cooling box through the water inlet pipe. When there is too much water in one cooling box, the diffused water enters the inner wall of other cooling boxes through the circulation pipe to complete the cooling of the cutting edge.

[0017] The present invention has the following beneficial effects:

[0018] (1) The present invention aims to solve the problem of processing components during pulverization. A pulverizing cooling mechanism is provided inside the device. When the device is used, the water inlet pipe is connected to the water inlet box, the material to be processed is placed inside the feed plate, and the motor is powered on. At this time, the motor drives the fan blades to rotate rapidly through the gear set. At this time, the water inside the water inlet box enters the pulverizing tube through the drive of the fan blades, and the pulverizing tube also rotates synchronously at this time. The centrifugal force generated by the pulverizing tube will force the water entering the pulverizing tube to diffuse around. The diffused water enters the cooling box through the water inlet pipe. When there is too much water in one cooling box, the water enters the inner wall of the other cooling box through the circulation pipe, thereby cooling the cutting edge. Through the application of the above-mentioned components, when the device is pulverizing, the internal water will cool the inner wall of the cutting edge, avoiding the high temperature generated inside the cutting edge after long-term operation, causing the plastic particles inside the device to melt, resulting in adhesion between the components and the plastic.

[0019] (2) When the present invention performs the above-mentioned cutting, the material enters the processing area through the feed plate, and after the processing is completed, it will fall on the top of the filter screen. At this time, it will present two states. When the components that meet the size fall on the top of the filter screen, they will be stirred by the crushing and cooling mechanism and finally pass through the holes of the filter screen and fall to the bottom of the outer chassis. The materials that do not meet the requirements will stay on the top of the filter screen and be cut by the crushing and cooling mechanism until the materials are crushed to the required size and pass through the filter screen. Through the application of the above-mentioned components, the size of the particles after the materials are crushed is guaranteed. In addition, taking advantage of the fact that the inside of the above-mentioned crushing tube is filled with water, a pressure slide plate is provided inside the equipment. When the fan blades continue to transport water to the inside of the crushing tube, the water pressure inside the crushing tube increases, and the high-pressure water will push the pressure slide plate to move outward along the inner wall of the crushing tube. In this process, the pressure slide plate drives the limiting ring to extend outward through the L-shaped frame, and the limiting ring slides along the bottom of the filter screen through the fixing plate, the pulling rod and the cleaning frame to remove impurities in the holes inside the filter screen.

[0020] (3) The present invention utilizes the characteristic of the regular movement of the pulling rod and provides a feeding mechanism inside the equipment. When the pulling rod moves, the linkage rod will be displaced synchronously. When the linkage rod is displaced, the linkage rod compresses the folding frame to bend. At this time, the sliding frame will be displaced left and right along the inner wall of the feeding plate, and the pushing square rod will move up and down along the inner wall of the sliding frame. When the pushing square rod moves up, the pushing square rod will be inserted into the plastic raw material, and the rotating square plate will be squeezed and move closer to the pushing square rod with the connection point as the center. When the pushing square rod moves down, the rotating square plate will be blocked by the material and will open to the surroundings. As the pushing square rod moves down, the internal material is forced to enter the outer chassis along the inside of the feeding plate. Through the application of the above components, the equipment can effectively avoid material blockage inside the feeding plate during processing, thereby affecting the processing efficiency of the equipment.

[0021] (4) The present invention utilizes the characteristics of the movement of the pressure slide plate and is provided with a piston plate inside the device. When the pressure slide plate moves outward due to high water pressure, the piston plate will force the liquid inside the hydraulic pipe to enter the other end through the holes of the piston plate. In this process, due to the limitation of the holes of the piston plate, the liquid will provide a large resistance to the piston plate when passing through the small holes, and the speed of the pressure slide plate moving outward will be simultaneously slowed down. When the pressure slide plate moves outward and forms a gap with the crushing tube for water to flow out, the high pressure disappears, and the pulling spring pulls the pressure slide plate to reset. At this time, the piston plate provides a resistance again, reducing the reset speed of the fixed plate. Through the application of the above components, the drainage efficiency of the device is increased when draining water. time, to avoid the temperature of the internal water source increasing and reducing the cooling effect of the equipment; in addition, a fixed plate is used to divide the interior of the pulverizing tube into two parts, front and back, so that when the equipment is performing the above-mentioned water discharge, the water source at the end of the pulverizing tube close to the pressure slide plate will be preferentially discharged, wherein due to the limitation of the fixed plate inside the pulverizing tube, when the equipment is draining water, the water source at the end of the pulverizing tube close to the pressure slide plate will be discharged outward through the gap between the pressure slide plate and the pulverizing tube, while the water source at the other end of the pulverizing tube will enter the end of the pulverizing tube close to the pressure slide plate through the cooling box and the circulation pipe. Through the application of the above-mentioned components, it is avoided that the water inside the pulverizing tube is directly discharged outward through the gap between the pressure slide plate and the pulverizing tube, which will affect the cooling effect of the cutting edge.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] For example, see Figure 1 - Figure 4 The present invention is a plastic processing pulverizing device, comprising a pulverizing and cooling mechanism 1, the pulverizing and cooling mechanism 1 also comprises an outer case 101, a gear set 102 is fixedly connected to the side wall of the outer case 101, two gears inside the gear set 102 are meshed with each other, a rotating tube 103 is rotatably connected to the side wall of the gear set 102, and one end of the rotating tube 103 away from the gear set 102 is through-connected to a water inlet tank 104;

[0036] The drainage mechanism 2 includes a fixed ring 201 fixedly connected to the side wall of the outer chassis 101, a telescopic frame 202 fixedly connected to the side wall of the fixed ring 201, and a limiting ring 203 fixedly connected to one end of the telescopic frame 202 away from the fixed ring 201;

[0037] The feeding mechanism 3 includes a feeding plate 301 connected to the top of the outer chassis 101 , a folding frame 302 is fixedly connected to the inner wall of the feeding plate 301 , and a sliding frame 303 is slidably connected to the inner wall of the feeding plate 301 .

[0038] The crushing and cooling mechanism 1 further comprises a motor 105 fixedly connected to the top of the water inlet tank 104 , the output shaft of the motor 105 is fixedly connected to a driving gear 106 , and the outer wall of the driving gear 106 is meshedly connected to the outer wall of the gear set 102 .

[0039] The pulverizing and cooling mechanism 1 also includes a pulverizing tube 107 fixedly connected to the side of the gear group 102 away from the rotating tube 103, a plurality of water inlet pipes 108 are opened at the side wall of the pulverizing tube 107, a fan blade 109 is fixedly connected to the inner wall of the gear group 102, a fixed plate 110 is fixedly connected to the inner wall of the pulverizing tube 107, a hydraulic pipe 111 is fixedly connected to the side wall of the fixed plate 110, a piston plate 112 is slidably connected to the inner wall of the hydraulic pipe 111, a push rod 113 is fixedly connected to the side wall of the piston plate 112, a pressure slide 114 is fixedly connected to the end of the push rod 113 away from the fixed plate 110, a pulling spring 115 is fixedly connected to the bottom of the pressure slide 114, and a piston plate 112 is arranged inside the device by utilizing the moving characteristic of the pressure slide 114. When the pressure slide 114 moves outward due to high water pressure, the piston plate 112 will force the liquid inside the hydraulic pipe 111 to enter the other end through the hole of the piston plate 112. In this process, due to the limitation of the hole of the piston plate 112, the liquid will provide a large resistance to the piston plate 112 when passing through the small hole, and the speed of the pressure slide 114 moving outward will be slowed down simultaneously. When the pressure slide 114 moves outward and forms a gap for water outlet with the crushing tube 107, the high pressure disappears, and the pulling spring 115 pulls the pressure slide 114 to reset. At this time, the piston plate 112 provides another resistance to reduce the reset speed of the fixed plate 110. Through the application of the above components, the drainage time of the equipment is increased when draining water, avoiding the increase of the internal water source temperature and reducing the cooling effect of the equipment.

[0040] The crushing and cooling mechanism 1 also includes a driving gear 106 fixedly connected to the inner wall of the water inlet pipe 108, and a cutting blade 117 is fixedly connected to the end of the driving gear 106 away from the crushing tube 107. The side walls of the plurality of cooling boxes 116 are connected with flow pipes 118. When using the device, the water inlet pipe is connected to the water inlet box 104, the material to be processed is placed inside the feed plate 301, and the power supply of the motor 105 is turned on. At this time, the motor 105 drives the fan blade 109 to rotate rapidly through the gear set 102. At this time, the water inside the water inlet box 104 enters the crushing tube 107 through the drive of the fan blade 109, and the crushing tube 1 07 also rotates synchronously at this time, and the centrifugal force generated by the crushing tube 107 will force the water entering the crushing tube 107 to diffuse around, and the diffused water enters the cooling box 116 through the water inlet pipe 108. When there is too much water in one cooling box 116, it enters the inner wall of other cooling boxes 116 through the circulation pipe 118, thereby cooling the cutting edge 117. Through the application of the above components, when the equipment is crushing, the internal water will cool the inner wall of the cutting edge 117, avoiding the high temperature generated inside the cutting edge 117 after long-term work, causing the plastic particles inside the equipment to melt, resulting in adhesion between the components and the plastic.

[0041] For example 2, please refer to Figure 5 - Fig. 9 The present invention is a plastic processing pulverizing device. On the basis of the first embodiment, the drainage mechanism 2 further comprises a plurality of L-shaped frames 204 rotatably connected to the inner wall of the limiting ring 203, the ends of the plurality of L-shaped frames 204 away from the limiting ring 203 are fixedly connected to the side wall of the pressure slide 114, the side wall of the limiting ring 203 is fixedly connected with a fixing plate 205, and the fixing plate 110 is used to divide the inside of the pulverizing tube 107 into two parts, front and rear, so that when the equipment performs the above-mentioned water discharge, the water source at one end of the pulverizing tube 107 close to the pressure slide 114 will be preferentially discharged, wherein the water source at the end of the pulverizing tube 107 close to the pressure slide 114 is fixedly connected to the side wall of the limiting ring 203. Due to the restriction of the fixed plate 110 inside the pulverizing tube 107, when the equipment is draining water, the water source at one end of the pulverizing tube 107 close to the pressure slide 114 is discharged outward through the gap between the pressure slide 114 and the pulverizing tube 107, and the water source at the other end of the pulverizing tube 107 will enter the end of the pulverizing tube 107 close to the pressure slide 114 through the cooling box 116 and the circulation pipe 118. Through the application of the above components, it is prevented that the water inside the pulverizing tube 107 is directly discharged outward through the gap between the pressure slide 114 and the pulverizing tube 107, which affects the cooling effect of the cutting blade 117.

[0042] The drainage mechanism 2 also includes a pulling rod 208 fixedly connected to the side wall of the fixing plate 205, a filter screen 206 fixedly connected to the inner wall of the outer chassis 101, a cleaning frame 209 fixedly connected to the outer wall of the pulling rod 208, a linkage rod 210 fixedly connected to the side wall of the pulling rod 208, and a collecting box 211 connected to the side wall of the outer chassis 101. When the above-mentioned cutting is performed, the material enters the processing area through the feeding plate 301, and will fall on the top of the filter screen 206 after processing. At this time, two states will be presented. When the components that meet the size fall on the top of the filter screen 206, they will be stirred by the crushing and cooling mechanism 1 and finally pass through the holes of the filter screen 206 and fall to the bottom of the outer chassis 101. The materials that do not meet the requirements will stay on the top of the filter screen 206 and be subjected to to the cutting of the crushing and cooling mechanism 1, until the material is crushed to the required size and passes through the filter 206. Through the application of the above-mentioned components, the size of the particles after the material is crushed is guaranteed; in addition, taking advantage of the fact that the inside of the above-mentioned crushing tube 107 is filled with water, a pressure slide 114 is provided inside the equipment. When the fan blades 109 continue to transport water to the inside of the crushing tube 107, the water pressure inside the crushing tube 107 increases, and the high-pressure water will push the pressure slide 114 to move outward along the inner wall of the crushing tube 107. In this process, the pressure slide 114 drives the limiting ring 203 to extend outward through the L-shaped frame 204, and the limiting ring 203 slides along the bottom of the filter 206 through the fixing plate 205, the pulling rod 208 and the cleaning frame 209 to remove impurities in the holes inside the filter 206.

[0043] The feeding mechanism 3 also includes a pushing square rod 304 slidably connected to the inner wall of the sliding frame 303, the bottom of the pushing square rod 304 is rotatably connected to the outer wall of the folding frame 302, the end of the pushing square rod 304 away from the folding frame 302 is fixedly connected to a fixed square plate 305, and the side wall of the pushing square rod 304 is rotatably connected to a rotating square plate 306. By utilizing the regular movement characteristics of the pulling rod 208, a feeding mechanism 3 is arranged inside the device. When the pulling rod 208 moves, the linkage rod 210 will be synchronously displaced. When the linkage rod 210 is displaced, the linkage rod 210 presses the folding frame 302 to bend, and at this time the sliding frame 303 will move along the feeding plate 301 The inner wall is displaced left and right, and the pushing square rod 304 will move up and down along the inner wall of the sliding frame 303. When the pushing square rod 304 moves up, the pushing square rod 304 will be inserted into the plastic raw material, and the rotating square plate 306 will be squeezed and move closer to the pushing square rod 304 with the connection point as the center. When the pushing square rod 304 moves down, the rotating square plate 306 is blocked by the material and will open to the surroundings. As the pushing square rod 304 moves down, the internal material is forced to enter the outer chassis 101 along the inside of the feed plate 301. Through the application of the above components, the equipment can effectively avoid material clogging inside the feed plate 301 during processing, thereby affecting the processing efficiency of the equipment.

[0044] The crushing method of the crushing device comprises the following steps:

[0045] S1: When using the equipment, connect the water inlet pipe to the water inlet box 104, place the material to be processed inside the feed plate 301, and turn on the power of the motor 105. At this time, the motor 105 drives the fan blade 109 to rotate rapidly through the gear set 102;

[0046] S2: The water in the water tank 104 is driven by the fan blades 109 to enter the grinding tube 107, and the grinding tube 107 also rotates synchronously at this time. The centrifugal force generated by the grinding tube 107 will force the water entering the grinding tube 107 to spread around;

[0047] S3: The diffused water enters the interior of the cooling box 116 through the water inlet pipe 108 . When there is too much water in one cooling box 116 , the diffused water enters the inner wall of the other cooling box 116 through the circulation pipe 118 , thereby cooling the cutting edge 117 .

[0048] A specific application of this embodiment is: when using the equipment, the water inlet pipe is connected to the water inlet box 104, the material to be processed is placed inside the feed plate 301, and the power supply of the motor 105 is turned on. At this time, the motor 105 drives the fan blade 109 to rotate rapidly through the gear set 102. At this time, the water inside the water inlet box 104 enters the inside of the crushing tube 107 through the drive of the fan blade 109, and the crushing tube 107 also rotates synchronously at this time. The centrifugal force generated by the crushing tube 107 will force the water entering the inside of the crushing tube 107 to diffuse around, and the diffused water enters the inside of the cooling box 116 through the water inlet pipe 108. When there is too much water in one of the cooling boxes 116, it enters the inner wall of the other cooling box 116 through the circulation pipe 118, thereby realizing the cooling of the cutting blade 117. Through the application of the above-mentioned components, when the equipment is crushing, the internal water will cool the inner wall of the cutting blade 117, so as to avoid the high temperature generated inside the cutting blade 117 after long-term work, causing the plastic particles inside the equipment to melt, resulting in adhesion between the components and the plastic.

[0049] When the above-mentioned cutting is performed, the material enters the processing area through the feed plate 301, and after the processing is completed, it will fall on the top of the filter screen 206. At this time, it will present two states. When the components that meet the size fall on the top of the filter screen 206, they will be stirred by the crushing and cooling mechanism 1 and finally pass through the holes of the filter screen 206 and fall to the bottom of the outer chassis 101. The materials that do not meet the requirements will stay on the top of the filter screen 206 and be cut by the crushing and cooling mechanism 1 until the materials are crushed to the required size and pass through the filter screen 206. The application of the parts ensures that the size of the particles after the material is crushed; in addition, taking advantage of the fact that the inside of the crushing tube 107 is filled with water, a pressure slide 114 is arranged inside the equipment. When the fan blades 109 continuously transport water to the inside of the crushing tube 107, the water pressure inside the crushing tube 107 increases, and the high-pressure water will push the pressure slide 114 to move outward along the inner wall of the crushing tube 107. In this process, the pressure slide 114 drives the limiting ring 203 to extend outward through the L-shaped frame 204, and the limiting ring 203 is connected to the fixing plate 205 and the pulling rod 208. The cleaning frame 209 slides along the bottom of the filter screen 206 to remove impurities in the holes inside the filter screen 206. By utilizing the regular movement characteristics of the pulling rod 208, a feeding mechanism 3 is arranged inside the device. When the pulling rod 208 moves, the linkage rod 210 will be synchronously displaced. When the linkage rod 210 is displaced, the linkage rod 210 presses the folding frame 302 to bend. At this time, the sliding frame 303 will be displaced left and right along the inner wall of the feeding plate 301, and the pushing square rod 304 will move up and down along the inner wall of the sliding frame 303. When the moving square rod 304 moves upward, the pushing square rod 304 will be inserted into the plastic raw material, and the rotating square plate 306 will be squeezed and move closer to the pushing square rod 304 with the connection point as the center. When the pushing square rod 304 moves downward, the rotating square plate 306 will be blocked by the material and will open to the surroundings. As the pushing square rod 304 moves downward, the internal material is forced to enter the outer chassis 101 along the inside of the feed plate 301. Through the application of the above components, the equipment can effectively avoid material clogging inside the feed plate 301 during processing, thereby affecting the processing efficiency of the equipment.

[0050] Taking advantage of the moving characteristics of the pressure slide 114, a piston plate 112 is provided inside the device. When the pressure slide 114 moves outward due to high water pressure, the piston plate 112 will force the liquid inside the hydraulic pipe 111 to enter the other end through the hole of the piston plate 112. In this process, due to the limitation of the hole of the piston plate 112, the liquid will provide a large resistance to the piston plate 112 when passing through the small hole, and the speed of the pressure slide 114 moving outward will be slowed down simultaneously. When the pressure slide 114 moves outward and forms a gap for water discharge with the crushing tube 107, the high pressure disappears, and the pulling spring 115 pulls the pressure slide 114 to reset. At this time, the piston plate 112 provides a resistance to reduce the reset speed of the fixed plate 110. Through the application of the above components, the drainage time of the device is increased when draining water, avoiding internal water sources. The temperature rises, reducing the cooling effect of the equipment; in addition, the fixed plate 110 is used to divide the interior of the pulverizing tube 107 into two parts, front and rear, so that when the equipment performs the above-mentioned water discharge, the water source at one end of the pulverizing tube 107 close to the pressure slide 114 will be preferentially discharged. Since there is a restriction of the fixed plate 110 inside the pulverizing tube 107, when the equipment is draining water, the water source at one end of the pulverizing tube 107 close to the pressure slide 114 will be discharged outward through the gap between the pressure slide 114 and the pulverizing tube 107, and the water source at the other end of the pulverizing tube 107 will enter the end of the pulverizing tube 107 close to the pressure slide 114 through the cooling box 116 and the circulation pipe 118. Through the application of the above-mentioned components, it is avoided that the water inside the pulverizing tube 107 is directly discharged outward through the gap between the pressure slide 114 and the pulverizing tube 107, which affects the cooling effect of the cutting blade 117.
