Description

Technical Field

[0001] The present application relates to the technical field of automobile plastic parts recycling and processing, and specifically discloses a recycling and processing device for automobile parts processing. Background Art

[0002] As the automotive industry moves towards lightweighting, plastics are used more and more widely in automobiles. Automotive plastic parts play a vital role in modern automobile manufacturing. They not only enhance the aesthetics of the vehicle body, but also provide the necessary protection for the vehicle, such as bumper housings, instrument panels, door interior panels, etc.

[0003] In the production process of automobile plastic parts, the recycling and reprocessing of plastics is essential. The reason is that plastic is a substance that is difficult to decompose naturally. If it is discarded at will or treated improperly by incineration, it will cause serious pollution to the atmosphere, soil and water. For example, burning plastics will produce harmful gases, such as dioxins, which will harm air quality; while landfilling will cause soil pollution and damage to groundwater resources. Through recycling and treatment, the generation of these pollutants can be effectively reduced. And for automobile manufacturers, the use of recycled plastic materials can reduce the procurement cost of raw materials. By recycling and reusing waste automobile plastic parts, the utilization efficiency of resources can be improved and the recycling of resources can be realized.

[0004] Usually, after plastics are collected and sorted, they also need to go through processes such as cleaning and crushing. After crushing, they also need to use magnetic separation to screen out metal impurities such as iron powder in the plastic to improve the purity of the plastic particles. The crushed plastic particles are then passed into a hot melt machine for injection molding.

[0005] Although magnetic separation can remove metal impurities in plastic during the plastic crushing process, it is not effective in screening some metal impurities with weaker magnetism. Usually, multiple processing steps are required to improve the purity of plastic particles, which increases the plastic recycling time and process cost. Therefore, the inventors have provided a recycling and processing device for automobile parts processing to solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to solve the problem that in the traditional plastic crushing process, the screening effect of metal impurities with weak magnetism is poor, which increases the plastic recycling processing time and process cost.

[0007] In order to achieve the above-mentioned object, the basic scheme of the present invention provides a recycling device for automobile parts processing, comprising:

[0008] frame;

[0009] A crushing chamber is arranged on the frame, a feed hopper is arranged on the top of the crushing chamber, and a crushing roller is symmetrically connected and rotated in the crushing chamber;

[0010] A water tank is arranged below the crushing roller, one end of the water tank is connected to a water inlet pipe, the other end of the water pipe is connected to a drainage trough, and the bottom of the water tank is connected to a discharge pipe;

[0011] A scraper slidably connected in the crushing chamber and scraping along the water surface of the water tank;

[0012] A driving mechanism for driving the crushing roller to rotate and the scraper to scrape.

[0013] The principles and effects of this basic solution are:

[0014] Since the main material in automotive plastic parts is PE plastic, its density is 0.91~0.97g / cm 3 The density of metal impurities such as iron powder is usually greater than the density of water at room temperature and pressure. Therefore, the present invention arranges a water tank below the crushing roller, and utilizes the characteristics of plastic floating on the water surface and metal impurities sinking to the bottom of the water to screen the plastic and metal impurities, so that the screening process can be carried out in time after the plastic is crushed, which effectively solves the problem of poor screening effect of metal impurities with weak magnetism in the traditional plastic crushing process, which increases the plastic recycling processing time and process cost.

[0015] Furthermore, the driving mechanism comprises:

[0016] A power member arranged on the frame;

[0017] Gears are respectively arranged between the crushing rollers and mesh with each other, one of which is drivingly connected to the output shaft of the power member;

[0018] A reciprocating screw rod rotatably connected to the side wall of the crushing bin, wherein the reciprocating screw rod is drivingly connected to one of the crushing rollers;

[0019] A sliding seat is threadably matched with the reciprocating screw rod, and the scraper is connected to the sliding seat.

[0020] With this arrangement, a power part is used to drive one of the crushing rollers to rotate, and the two crushing rollers are made to rotate relative to each other through the meshing gears between the two crushing rollers to crush the plastic recycling products. At the same time, one of the crushing rollers is used to drive the reciprocating screw to rotate, and the mutual cooperation between the reciprocating screw and the slide seat is used to drive the scraper to scrape the surface of the water tank.

[0021] Further, the driving mechanism further comprises a scraper adjustment assembly, the scraper adjustment assembly comprises a connecting frame vertically slidably connected to the slide seat and a guide groove arranged in the crushing bin, the guide groove comprises a first limit groove, a second limit groove and an inclined groove arranged from bottom to top and parallel to each other, one end of the connecting frame is slidably connected in the guide groove, and the other end of the connecting frame is connected to the scraper;

[0022] When the scraper moves along the water inlet pipe to the drainage groove, one end of the connecting frame is slidably connected in the first limiting groove; when the scraper moves along the slide groove to the water inlet pipe, one end of the connecting frame is slidably connected in the second limiting groove.

[0023] With this arrangement, when the scraper moves along the water inlet pipe toward the drain trough, it scrapes along the surface of the water tank, thereby scraping the plastic that floats to the horizontal into the drain trough. When the scraper moves in the opposite direction, the scraper loses contact with the water tank, preventing the scraper from scraping the plastic in the opposite direction and causing some of the plastic to accumulate in the corners of the water tank.

[0024] Furthermore, one end of the inclined groove is smoothly transitioned with the first limiting groove or the second limiting groove, and the other end of the inclined groove is connected with the side wall of the first limiting groove or the second limiting groove. This setting limits the sliding position of the connecting frame to prevent the connecting frame from getting stuck during the sliding process.

[0025] Furthermore, one end of the inclined groove communicating with the side wall of the first limiting groove or the second limiting groove is hinged with a baffle covering the end of the inclined groove, and a torsion spring is provided at the hinge of the baffle. Through this arrangement, the baffle can limit the sliding path of the connecting frame, so that the connecting frame slides along a set path, thereby preventing the connecting frame from being misplaced and affecting the normal operation of the scraper.

[0026] Furthermore, a fixing frame is provided on the slide seat, a vertical through slot is provided on the fixing frame, and the connecting frame passes through the through slot and is vertically slidably connected to the through slot. The cooperation between the through slot and the connecting frame plays a role of limiting and guiding the vertical sliding of the connecting frame.

[0027] Furthermore, the driving mechanism further comprises a fixed plate arranged in the crushing chamber and a slide groove arranged on the fixed plate, and the slide seat is slidably connected to the slide groove. The cooperation between the slide seat and the slide groove plays a role of limiting and guiding the sliding of the slide seat.

[0028] Furthermore, the scraper is provided with an arc-shaped concave surface, a rotating shaft is rotatably connected in the arc-shaped concave surface, a plurality of blades are evenly arranged at the circumferential end of the rotating shaft, and a matching component for driving the rotating shaft to rotate is arranged in the crushing chamber. The rotating shaft and the blades are arranged so that the scraper can stir the plastic on the water surface in the water tank to below the water surface to fully contact the water during the scraping process, so as to avoid some metal impurities adhering to the plastic and floating on the water surface, resulting in the problem of incomplete removal of metal impurities.

[0029] Furthermore, the mating assembly includes a mating rack provided in the crushing chamber and a mating gear provided on the rotating shaft and meshing with the mating rack. Through the mutual cooperation between the mating rack and the mating gear, the mating gear and the mating rack can rotate relative to each other during the movement of the scraper, thereby driving the rotating shaft and the blades to rotate.

[0030] Furthermore, the drainage trough is connected to a filter, which performs solid-liquid separation on the plastic and water in the drainage trough, so as to facilitate the next step of processing of the plastic. BRIEF DESCRIPTION OF THE DRAWINGS

The power member adopts a servo motor 4, and the gear pair includes two gears that are meshed with each other, one of which is a driving gear and is coaxially connected to the servo motor 4 through the roller shaft 5.

[0042] like Figure 3 and Figure 4 As shown, a slide 10 is slidably connected in the crushing chamber 2, the slide 10 is threadedly connected to the reciprocating screw 9, and a fixed plate 11 is adapted between the water tank 7 and the inner wall of the crushing chamber 2, a dovetail-shaped slide groove is provided on the fixed plate 11, and the bottom of the slide 10 is slidably connected to the slide groove, thereby limiting and guiding the sliding of the slide 10.

[0043] A fixing frame 19 is installed on the slide 10, and a through slot is vertically provided on the fixing frame 19. A connecting frame is vertically slidably connected in the through slot. The connecting frame includes a cross bar 18 vertically slidably connected to the through slot, a vertical bar 17 arranged at one end of the cross bar 18 close to the water tank 7, and a sliding bar arranged at the other end of the cross bar 18.

[0044] A rotating shaft 14 is rotatably connected to the bottom of the vertical rod 17, and both ends of the rotating shaft 14 are rotatably connected to the vertical rods 17 on both sides. The middle of the two vertical rods 17 are respectively connected to a scraper 16 through an ear piece. The scraper 16 is provided with an arc-shaped concave surface. The rotating shaft 14 is rotatably connected to the arc-shaped concave surface and a plurality of blades 15 are provided on its surface.

[0045] The driving mechanism also includes a scraper 16 adjustment component and a matching component, wherein the matching component includes a matching rack 12 symmetrically arranged on the fixing plate 11 on both sides of the water tank 7 and a matching gear 13 arranged at both ends of the rotating shaft 14 and meshing with the matching rack 12.

[0046] The scraper 16 adjustment assembly includes a guide block 20 disposed on the inner side wall of the crushing chamber 2 and a guide groove 21 formed on the guide block 20. Figure 5 As shown, the guide groove 21 includes a first limit groove, a second limit groove and an inclined groove arranged from bottom to top and parallel to each other. The top of the inclined groove on the left side smoothly transitions with the left end of the second limit groove, the bottom of the inclined groove on the left side is connected to the side of the first limit groove, the bottom of the inclined groove on the right side smoothly transitions with the right end of the first limit groove, the top of the inclined groove on the right side is connected to the side wall of the second limit groove, the bottom of the inclined groove on the left side and the top of the inclined groove on the right side are both hinged with a baffle 23 covering the end of the inclined groove, the baffle 23 is connected to the guide block 20 through a hinge ear 22 and a torsion spring is provided on the hinge ear 22.

[0047] In this embodiment, the plastic is collected and classified and then passed into the crushing bin 2 through the feed hopper. The servo motor 4 drives the two crushing rollers 3 to rotate through the gear pair, so that the two crushing rollers 3 rotate relative to each other to crush the plastic. The crushed plastic falls into the water tank 7 through the guide plate 8. The side wall of the water tank 7 continues to flow with water. The plastic floats to the water surface, while the metal impurities sink to the bottom of the water. In this process, the crushing roller 3 drives the reciprocating screw 9 to rotate through the belt transmission pair, and the reciprocating screw 9 drives the slide 10 to move back and forth, so that the plastic can be crushed. Figure 5Taking the direction shown as an example, when the slide 10 moves from left to right, the end of the slide rod slides along the first limiting groove, and the matching rack 12 and the matching gear 13 are meshed with each other, the scraper 16 scrapes along the water surface, and at the same time the rotating shaft 14 and the blade 15 rotate, stirring the plastic on the water surface in the water tank 7 to below the water surface to fully contact with the water, so as to avoid some metal impurities adhering to the plastic and floating on the water surface. Under the action of the scraper 16, the plastic enters the filter through the drainage groove, and the plastic enters the next processing technology after solid-liquid separation. When the slide rod moves to the right end of the first limiting groove, it enters the inclined groove on the right and drives the scraper 16 to move upward as a whole, pushing the baffle 23 to enter the right end of the second limiting groove, and then the reciprocating screw 9 drives the slide 10 to move left, and the slide 10 moves along the second limiting groove and the inclined groove on the left to the left end of the first limiting groove. In this process, the scraper 16 is out of contact with the water surface in the water tank 7, so as to avoid the scraper 16 scraping the plastic in the opposite direction, causing some plastic to accumulate in the corner of the water tank 7.

[0048] The present invention is based on the fact that the main material of automobile plastic parts is PE plastic, and its density is between 0.91 and 0.97 g / cm3, which is less than the water density at normal temperature and pressure, while the density of metal impurities such as iron powder is usually greater than the water density at normal temperature and pressure. The plastic and metal impurities are screened by utilizing the characteristics that plastic floats on the water surface and metal impurities sink to the bottom of the water, so that the screening process is carried out in time after the plastic is crushed, which effectively solves the problem of poor screening effect on metal impurities with weak magnetism in the traditional plastic crushing process, which increases the plastic recycling processing time and process cost.
