Description

Technical Field

[0001] This utility model relates to the field of automotive interior parts foam raw material processing technology, specifically to an automotive interior parts foam raw material pretreatment device with a waste recycling structure. Background Technology

[0002] The processing of foam materials for automotive interior parts is a key process that improves the performance of foam materials through physical or chemical methods to meet the requirements of lightweighting, comfort, and safety. Commonly used raw materials include polyurethane and polypropylene. The processing flow includes raw material mixing, foaming agent dispersion, modification, and reinforcement. The processed foam material has excellent cushioning and shock absorption properties and is suitable for interior parts such as seats, dashboards, and door panels. It can reduce interior noise and improve ride comfort. Modern processes are trending towards environmental friendliness, such as using water-based foaming agents to replace chlorofluorocarbons (CFCs) to reduce VOC emissions, which aligns with the green manufacturing trend in the automotive industry. However, existing foam pretreatment equipment still has certain problems in use. For example, a foaming pretreatment device with application number 202221301959.5 has the following technical solution: it includes a pretreatment cylinder, a disc-shaped fixed box is fixedly installed on the inner bottom wall of the pretreatment cylinder, and a first rotating tube and a second rotating tube are rotatably connected to the inner bottom wall of the disc-shaped fixed box respectively. The top end of the second rotating tube extends into the interior of the pretreatment cylinder, and an auger is provided on the surface of the second rotating tube. A connecting box and a heating box are fixedly installed on the upper surface of the pretreatment cylinder respectively, and the top end of the first rotating tube extends into the interior of the connecting box and is rotatably connected to the inner top wall of the connecting box. However, the existing foaming pretreatment device suffers from insufficient process stability due to the adhesion of raw materials to the inner wall. The raw materials are prone to adhere to the tank wall to form stubborn scale. The adhering waste generated during the pretreatment process is difficult to recycle due to the presence of metal impurities or chemical cross-linking.

[0003] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0004] To address the aforementioned issues, an innovative design was implemented based on the existing foaming pretreatment device. Summary of the Invention

[0005] The purpose of this invention is to provide a pretreatment device for foamed raw materials of automotive interior parts with a waste recycling structure, so as to solve the problems mentioned in the background art of foamed raw materials easily adhering to the inner wall and the difficulty in recycling waste.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A pretreatment device for foamed raw materials of automotive interior parts with a waste recycling structure includes a device shell. The device shell is cylindrical with a conical bottom. Support legs are fixedly installed on the left and right sides of the bottom of the device shell. A feed inlet is provided on the left side of the device shell, and a discharge outlet is provided on the bottom of the device shell. An air hole is provided on the top surface of the device shell. A stirring rod is provided inside the lower part of the device shell, and the stirring rod rotates to form a stirring structure. A protective box is fixedly installed on the top surface inside the device shell, and a limit sleeve is fixedly installed below the protective box. A connecting rod slides through the limit sleeve, and a cleaning scraper is fixedly installed on the outside of the connecting rod. The cleaning scraper is in close contact with the inside of the device shell to form a reciprocating up-and-down movement structure.

[0007] Preferably, a first motor is fixedly installed on the top surface of the device housing, and a first rotating rod is connected and installed at the output end below the first motor. A mounting base is fixedly installed at the bottom of the first rotating rod, and four stirring rods are fixedly installed on the outside of the mounting base.

[0008] Using the above technical solution, the first motor drives the first rotating rod and the four stirring rods on the outside of the mounting base to rotate, forming a multi-directional stirring structure, which can quickly and evenly mix the foaming raw materials and additives, improve the pretreatment efficiency, and improve the mixing uniformity.

[0009] Preferably, the interior of the protective box is connected to the interior space of the limiting sleeve, and four sliding grooves are provided on the outer side of the limiting sleeve.

[0010] With the above technical solution, the internal space of the protective box and the limiting sleeve are connected, and four sliding grooves are opened on the outside of the limiting sleeve to guide the sliding of the connecting rod, ensuring that the cleaning scraper moves smoothly up and down and avoiding shaking that leads to incomplete scraping.

[0011] Preferably, a second motor is fixedly installed on the upper right side of the device housing, and a second rotating rod is connected to the left output end of the second motor, and a first bevel gear is fixedly connected to the left end of the second rotating rod.

[0012] Using the above technical solution, the second motor drives the first bevel gear to rotate through the second rotating rod, converting the horizontal rotational motion of the motor into vertical transmission, providing a power source for the rotation of the reciprocating screw, and realizing the automated control of the cleaning structure.

[0013] Preferably, the first bevel gear is meshed with a second bevel gear on its left side, and the second bevel gear is rotatably connected to the top surface inside the device housing. A reciprocating screw is fixedly connected to the bottom of the second bevel gear, and the first rotating rod passes through both the second bevel gear and the reciprocating screw.

[0014] Using the above technical solution, the first bevel gear meshes with the second bevel gear to drive the reciprocating screw to rotate. At the same time, the first rotating rod passes through the second bevel gear and the reciprocating screw, realizing the synchronous linkage of stirring and cleaning actions. No additional power source is required, simplifying the mechanical structure.

[0015] Preferably, the reciprocating lead screw passes through the inside of the limiting sleeve, and a moving block is threadedly connected to the outside of the reciprocating lead screw.

[0016] Using the above technical solution, the reciprocating screw is threadedly connected to the moving block, which converts the rotational motion into the up-and-down linear motion of the moving block, thereby driving the connecting rod and the cleaning scraper to move back and forth along the sliding groove of the limiting sleeve, automatically removing the raw material adhering to the inner wall of the device housing.

[0017] Preferably, the connecting rod is fixedly connected to the outside of the moving block, and the connecting rod is slidably connected to the inside of the groove.

[0018] Using the above technical solution, the connecting rod is fixedly connected to the moving block and slidably connected to the slide groove, ensuring that the cleaning scraper is in close contact with the inner wall of the device housing, improving the scraping effect, while limiting the lateral displacement of the cleaning structure and enhancing the stability of movement.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the pretreatment device for foaming raw materials of automotive interior parts with a waste recycling structure, 1. Prevent raw materials from sticking to the inner wall: The second motor drives the reciprocating screw to rotate through bevel gear transmission, causing the cleaning scraper to move up and down to scrape off the raw materials adhering to the inner wall, avoiding the raw materials from solidifying due to long-term adhesion and affecting the pretreatment quality, and the single treatment cycle can be shortened. 2. Automatic waste recycling and anti-sticking structural design: The cleaning scraper scrapes the adhered waste to the conical area at the bottom of the device shell, and collects it through the discharge port. This solves the problem of waste mixing into raw materials or being difficult to clean in traditional devices. The conical bottom design reduces dead corners where raw materials are stuck. Combined with the close-fitting movement of the cleaning scraper, the adhesion rate on the inner wall is reduced. Attached Figure Description
