Description

Technical Field

[0001] This invention relates to the field of automotive interior parts waste recycling technology, specifically to a waste recycling device for automotive interior parts production. Background Technology

[0002] Automotive interior parts mainly refer to automotive products used for modifying the interior of a car, covering all aspects of the car's interior, such as steering wheel covers, car seat cushions, car floor mats, car perfumes, car pendants, interior decorations, storage boxes, etc. The production of automotive interior parts generates a large amount of waste, which needs to be recycled and reused. However, existing equipment cannot operate smoothly when crushing waste, and patent documents have been issued to improve this.

[0003] For example, Chinese patent CN111195999A discloses a waste recycling device for automotive interior parts production, which includes a base. A box is fixedly connected to one side of the top of the base, and a feeding cylinder is bolted to the top of one side of the box. A feeding plate is fixedly connected to the inner wall of the middle of the feeding cylinder, and the bottom of the feeding plate extends into the interior of the box. During the use of this invention, the gap between the waste and the crushing roller gradually decreases as the waste slides down the feeding plate, which can be fully squeezed and effectively reduce the volume of the waste, facilitating further crushing. The crushing teeth on the surface of the crushing roller can increase the pressure applied to the waste and optimize the crushing effect. The air pipe connector is connected to the air supply system, and airflow is blown onto the crushing roller through the nozzle to clean the debris adhering to the surface of the crushing roller. The reduced-volume waste falls between the driving roller and the driven roller, where it is further crushed by the meshing blades.

[0004] While the equipment described in the above document can improve crushing efficiency and quality, it still has significant drawbacks in actual use, such as:

[0005] Currently, most automotive interior parts are made of plastic, but their surfaces are coated with leather using special adhesives to form a complete interior part. When recycling interior parts, the equipment can only crush the interior parts, but cannot separate the leather from the plastic. As a result, during subsequent recycling, the plastic cannot be heat-fused because it is stuck to the leather. Furthermore, the small size of the crushed interior parts makes it inconvenient to separate the leather. If manual separation is required before crushing, it increases the workload and costs.

[0006] Therefore, a waste recycling device for automotive interior parts production that can effectively separate leather has been designed to address this defect. Summary of the Invention

[0018] This invention provides a waste recycling device for the production of automotive interior parts. Compared with existing technologies, it has the following advantages:

[0019] (1) The waste recycling device for automotive interior parts production combines the heating separation mechanism and the flotation separation mechanism. The two mechanisms can heat the interior parts while crushing them, thereby softening the colloid. When the crushed material enters the conveying separation box, the plastic and leather can be separated by the high-pressure airflow sprayed from the fan-shaped nozzle due to the small size of the crushed material. Then, the plastic and leather are conveyed to the second processing tank for stratification. Finally, the plastic and leather are lifted out by the lifting of the cylinder and the fan-shaped nozzle is cleaned by the cooperation between the structures, thereby effectively separating the plastic and leather, which facilitates the subsequent recycling and processing of different materials, improving the recycling efficiency and reducing the workload of the workers.

[0020] (2) The waste recycling device for automotive interior parts production is equipped with a mesh cylinder ring column and auger blades on the inner side of the conveying and separating box, and a horizontal air duct and fan-shaped air nozzles are installed on the inner side of the mesh cylinder ring column. It is used in conjunction with an electric heater. The structure can heat the crushed material at high temperature, softening the glue between the leather and plastic. When the mesh cylinder ring column drives the auger blades to rotate and convey the material, it will also drive the horizontal air duct and several fan-shaped air nozzles to rotate. The auger blades stir the crushed material while conveying it, so that the high-pressure airflow sprayed from the fan-shaped air nozzles can contact the crushed material more evenly, thereby separating the leather and plastic without manual peeling, which reduces labor costs and facilitates use.

[0021] (3) The waste recycling device for automotive interior parts production has a vertical frame installed inside the linkage tank, and inclined mesh seats and mesh plates are set on the surface and inside of the vertical frame respectively. It is used in conjunction with toothed plates, overlapping rods and upper baffles. The structure can separate plastic and leather by using the difference in material density after the scrap enters the second processing tank. When the cylinder drives the vertical frame to rise, it will first rotate the mesh plate to a horizontal state to pick up the plastic. When it rises to the top, it can open the rectangular material port and completely flip the mesh plate, so that both plastic and leather are discharged. During this process, the sealing seat will continue to feed the material, and the mesh plate will squeeze the curved frame, thereby driving the scraper to clean the fan-shaped air nozzle, effectively ensuring the stability of the equipment during operation.

[0022] (4) The waste recycling device for automotive interior parts production is used by setting an L-shaped guide frame at the front of the conveying and separating box, and using an exhaust pipe and a water filter. The structure allows water to flow into the interior of the L-shaped guide frame after the rectangular material inlet is opened, cleaning the dust inside the L-shaped guide frame. At the same time, the water filter can effectively filter water from the leather, ensuring the cleanliness inside the L-shaped guide frame. Attached Figure Description

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Please see Figures 1-14 The present invention provides a technical solution: a waste recycling device for automotive interior parts production, comprising a heating separation mechanism 1 and a flotation separation mechanism 2;

[0040] Please refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8The overall structure of the heating separation mechanism 1 is shown. The heating separation mechanism 1 includes a heating box 101. A conveying separation box 102 is fixedly connected to the left side of the heating box 101 through an opening. A crusher 103 is fixedly installed on the top of the heating box 101 through an opening. Electric heaters 104 are fixedly installed at the front and rear of the heating box 101 through openings. A high-pressure air pump 105 is fixedly installed on the right side of the heating box 101, and the air outlet of the high-pressure air pump 105 is fixedly connected to the main air duct 106. The flotation and material distribution mechanism 2 includes a flotation box 201, which is fixedly installed on the left side of the rear of the conveying separation box 102 and is connected to the conveying separation box 102.

[0041] An annular slide plate 107 is fixedly installed on the right side of the inner cavity of the heating chamber 101. A mesh cylinder ring column 108 is rotatably connected to the inner side of the annular slide plate 107, and one end of the mesh cylinder ring column 108 extends into the interior of the heating chamber 101. An auger blade 109 is fixedly connected to the surface of the mesh cylinder ring column 108, and the auger blade 109 is in contact with the inner wall of the heating chamber 101. A motor 110 is fixedly connected to the left side of the heating chamber 101 via a bracket. The motor 110 is a servo motor, and the output shaft of the motor 110 is connected via... A rotating rod 111 is fixedly connected to the coupling, and one end of the rotating rod 111 passes through the heating box 101 and is fixedly connected to the left side of the mesh cylinder ring column 108. The bottom end of the main air duct 106 is rotatably connected to the transverse air duct 112 through the bearing component, and the left end of the transverse air duct 112 passes through the heating box 101 and the annular slide plate 107 in sequence and extends to the inside of the mesh cylinder ring column 108. One end of the transverse air duct 112 extending into the inside of the mesh cylinder ring column 108 is fixedly connected to the inner wall of the mesh cylinder ring column 108 through the bracket.

[0042] Both the front and rear of the horizontal duct 112 have fan-shaped nozzles 113 fixedly installed through openings, and several fan-shaped nozzles 113 are provided. Both the front and rear of the horizontal duct 112 are fixedly connected to guide plates 114, and the number of guide plates 114 is the same as the number of fan-shaped nozzles 113. Scraper plates 115, which cooperate with the fan-shaped nozzles 113, are slidably installed on the inner side of the guide plates 114. A stop disc 116 is fixedly connected between the bottoms of several scraper plates 115 through a bracket, and the stop disc 116 is sleeved on the surface of the horizontal duct 112. A first spring 117 is sleeved on the surface of the horizontal duct 112. The flotation tank 201... An L-shaped guide frame 118 is fixedly connected to the left side. A water filter 120 is fixedly connected to the top left side of the L-shaped guide frame 118. An exhaust pipe 119 is fixedly connected to the surface of the heating box 101 through an opening. One end of the exhaust pipe 119 passes through the L-shaped guide frame 118 and extends to the inside of the L-shaped guide frame 118. On the right side of the inner cavity of the heating box 101 and inside the annular slide plate 107, a push rod 121 that works with the stop disc 116 is slidably installed through an opening. A bent frame 122 is fixedly connected to the end of the push rod 121 outside the heating box 101. The bent frame 122 is located at the rear of the heating box 101.

[0043] In use, first connect the water injection pipe 226 to the water source, then inject water into the inner side of the second treatment tank 203 and add salt to the water. Then start the high-pressure air pump 105 and the motor 110. After the high-pressure air pump 105 starts, it will blow high-pressure air through the main air duct 106. At the same time, the motor 110, using the rotating rod 111 and the limiting action of the annular slide plate 107, drives the mesh cylinder ring column 108 and the auger blades 109 to rotate. Since the transverse air duct 112 is rotatably connected to the main air duct 106 via bearing components, the transverse air duct 112 will also rotate. Then, the car... Interior trim parts are fed into the crusher 103 for crushing, and the scrap falls into the heating chamber 101. The electric heater 104 raises the temperature inside the heating chamber 101, softening the scrap. The scrap is then conveyed by the auger blades 109 into the conveying and separating chamber 102. At this point, the main air duct 106 injects high-pressure gas into the transverse air duct 112, and the high-pressure gas is then ejected outwards through the fan-shaped nozzles 113. Because the scrap has been pre-heated and softened, the colloid between the plastic and leather also softens. The ejected high-pressure gas then separates the plastic from the leather. The leather undergoes blowing and pressing separation. Simultaneously, dust from the fragments is discharged through exhaust pipe 119 along with the gas, falling inside the L-shaped guide frame 118. The separated plastic and leather are then conveyed to the far left and enter the storage tank 223 through inlet 227. At this point, the storage tank 223 is sealed by the first processing tank 202 to store the fragments. Then, cylinder 219 is activated, causing the sealing seat 222 and vertical frame 210 to rise synchronously. When they reach the top, the storage tank 223 is no longer obstructed, and the fragments inside slide into the second processing tank 203. In the water, the lower part of the sealing seat 222 will seal the feed inlet 227 to prevent the debris from overflowing. After the debris inside the storage tank 223 has completely entered the second processing tank 203, the cylinder 219 will drive the sealing seat 222 to descend to the bottom of the first processing tank 202. At this time, the storage tank 223 will reconnect with the feed inlet 227, and the debris will enter the storage tank 223 again for storage. Meanwhile, due to the different densities of the plastic sheets and leather inside the second processing tank 203, the plastic sheets will eventually float to the surface, while the leather will sink to the top of the inclined mesh seat 213.

[0044] Please refer to Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 14The diagram illustrates the overall structure of the flotation distribution mechanism 2. The flotation tank 201 has a first processing tank 202 and a second processing tank 203 inside. A linkage groove 204 is located at the rear of the inner cavity of the second processing tank 203. A rectangular feed inlet 205, communicating with the second processing tank 203, is located on the left side of the flotation tank 201. A sealing frame 206, which mates with the rectangular feed inlet 205, is fixedly connected to the left side of the flotation tank 201. A rebound rod 207 is fixedly connected to the left side of the flotation tank 201, above the rectangular feed inlet 205. A sealing baffle 208 is slidably mounted on the surface of the rebound rod 207, and the sealing baffle 208 is located inside the sealing frame 206. A second spring 209 is sleeved on the surface of the rebound rod 207. A vertical frame 210 is slidably installed on the inner side of the groove 204. An inclined mesh seat 213 is fixedly connected to the surface of the vertical frame 210, and the inclined mesh seat 213 is located inside the second processing groove 203. A mesh plate 211 is rotatably connected between the two sides of the inner cavity of the vertical frame 210 through an opening. Gears 212 are fixedly connected to both ends of the mesh plate 211. Lifting rods 214 are fixedly connected to the top of both sides of the vertical frame 210. A buffer rod 215 is fixedly connected to the bottom end of the lifting rod 214 through a fixing plate. A toothed plate 217 that meshes with the gear 212 is slidably installed on the surface of the buffer rod 215. A third spring 216 is sleeved on the surface of the buffer rod 215. A blocking plate 218 is fixedly connected to the rear of the toothed plate 217.

[0045] A cylinder 219 is fixedly installed on the right side of the flotation box 201. A special-shaped top plate 220 is fixedly connected to the top of the cylinder 219. An L-shaped arc plate 221 that cooperates with the sealing baffle 208 and the curved frame 122 is fixedly connected to the bottom of the special-shaped top plate 220 through a bracket. A feed inlet 227 that cooperates with the conveying and separating box 102 is opened on the surface of the flotation box 201. A sealing seat 222 is provided on the inner side of the first processing tank 202. A storage tank 223 that extends through to the other side is opened on one side of the sealing seat 222. An overlapping rod 224 that cooperates with the mesh plate 211 is fixedly connected to the rear of the flotation box 201 through a bracket. Upper baffle plates 225 that cooperate with the toothed plate 217 are fixedly connected to both sides of the rear of the flotation box 201. A water injection pipe 226 is provided on the upper left side of the flotation box 201.

[0046] After separation is complete, cylinder 219 drives the sealing seat 222 and vertical frame 210 to rise again. At this time, the mesh plate 211 inside the vertical frame 210 rises accordingly, while gear 212 first meshes with toothed plate 217 and drives mesh plate 211 to rotate 90 degrees counterclockwise to a horizontal position. At this time, the third spring 216 contacts the bottom of toothed plate 217. As the vertical frame 210 continues to rise, toothed plate 217 will also rise synchronously with gear 212, thus making gear 212 and toothed plate 217... In a relatively stationary state, the side gear 212 will not continue to drive the mesh plate 211 to rotate. After the blocking plate 218 rises and contacts the upper blocking plate 225, it will stop the toothed plate 217 from rising further. However, at this time, the vertical frame 210 will still drive the gear 212 and the buffer rod 215 to rise, compressing the third spring 216. At the same time, the mesh plate 211 in the horizontal state will scoop up the plastic sheet on the water surface, and when the gear 212 rises, it will drive the mesh plate under the meshing action of the toothed plate 217. 211 continues to flip until cylinder 219 rises to the top. At this point, the mesh plate 211 flips over and overlaps the top of the overlapping rod 224, simultaneously dumping out the top fragments. Simultaneously, after cylinder 219 rises to the top, the L-shaped arc plate 221 also presses against the sealing baffle 208 and the bent frame 122. After the bent frame 122 is pressed, it pushes the push rod 121 to the left, thus pressing against the blocking disc 116, which in turn moves several scraper plates 115 to the left to scrape and remove dirt from the air outlet of the fan-shaped nozzle 113. After the sealing baffle 208 is lifted, the rectangular feed opening 205 is exposed. At this time, the inclined mesh seat 213 also rises to the rectangular feed opening 205. Then the leather fragments flow out with the water. At this time, the filter bucket 120 catches the leather, and the water flows into the inside of the L-shaped guide frame 118 for rinsing. When the material is put into the second processing tank 203, a small amount of leather fragments will also be discharged along with it. Then the cylinder 219 descends and resets, and the mesh plate 211 flips back to the inside of the vertical frame 210.
