Description

Technical Field

[0001] This utility model relates to the field of automotive trim processing technology, and more specifically, it relates to a granulator for automotive trim. Background Technology

[0002] Automotive plastic trim parts are an important component of vehicle interiors and exteriors, offering advantages such as lightweight, corrosion resistance, and ease of molding. Common exterior trim parts include front and rear bumpers, grilles, side skirts, and wheel arches, while interior trim parts include dashboards, door panel trims, and center console decorations. Made from engineering plastics such as ABS, PP, and PC, and manufactured through processes like injection molding and painting, they combine aesthetics and practicality. Plastic trim parts offer flexible design options to meet diverse styling needs, while also being relatively inexpensive and easy to mass-produce, making them widely used in the automotive industry.

[0003] To transform raw materials (such as plastics and rubber) into uniform granules for easier subsequent processing and molding, granulators are used in the production of automotive trim parts. Granulators melt, extrude, and cut large chunks or powdery raw materials into uniformly sized granules, ensuring the material's flowability and uniformity in injection molding, extrusion, and other processes. This not only improves production efficiency but also guarantees the quality and consistency of automotive trim parts, while reducing raw material waste and lowering production costs.

[0004] Existing automotive trim granulators typically melt the raw material, extrude it into strips, cool and shape it, and then cut it. The cooling method is mainly water cooling. During the cutting process, water stains are easily left on the surface of the plastic strips used for cutting, which affects the performance of the granulated products.

[0005] Furthermore, in the existing technology, when granulating and cutting automotive decorative parts, the cutter needs to repeatedly cut the plastic strip. Over time, this can easily reduce the sharpness of the cutter, affecting the cutting effect, and may even cause the particles to stick together due to poor cutting. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] To address the problems existing in the prior art, this utility model provides a granulator for automotive decorative parts, which solves the technical problems mentioned in the background art, such as water stains easily being carried on the feed strips of the prior art granulator for automotive decorative parts, and the sharpness of the cutting blade easily decreasing due to repeated use.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A granulator for automotive trim parts includes a conveyor table, a mounting frame on the conveyor table, a first electric push rod on the mounting frame, a cutting blade at the bottom of the first electric push rod, grinding blocks on both sides of the cutting blade, a movement control component on the mounting frame in conjunction with the grinding blocks, a cutting table on the conveyor table in conjunction with the cutting blade, a conveying component behind the cutting table, a lower wiper seat behind the conveying component, an upper wiper seat above the lower wiper seat, a second electric push rod on the upper wiper seat, the second electric push rod being mounted on the mounting frame, a collection box in front of the cutting table, a screening structure inside the collection box, and a discharge pipe at the bottom of the collection box.

[0011] The present invention is further configured such that the conveying assembly includes a lower conveying roller, the lower conveying roller is disposed on a conveying platform, a driving assembly is disposed on the conveying platform in cooperation with the lower conveying roller, and an upper conveying roller is disposed above the lower conveying roller that can be raised and lowered, thereby realizing the conveying of plastic filaments for pelletizing through the cooperation of the upper and lower conveying rollers.

[0012] The present invention is further configured such that a third electric push rod is provided on the mounting frame, and a clamping frame is provided at the output end of the third electric push rod. The upper conveying roller is rotatably mounted on the clamping frame through a bearing and is positioned in conjunction with the lower conveying roller. When the third electric push rod is activated, the clamping frame is controlled by the third electric push rod to drive the upper conveying roller to descend, thereby cooperating with the lower conveying roller to realize the extrusion and conveying of plastic filaments for pelletizing.

[0013] The present invention is further configured such that the driving component includes a driving motor, the output end of the driving motor is connected to one of the lower conveying rollers, and a synchronous belt drive structure is provided between two adjacent conveying rollers. When the driving motor is started, the rotation of the lower conveying roller can be controlled by the cooperation of the driving motor and the synchronous belt drive structure, thereby cooperating with the upper conveying roller to realize the conveying of plastic filaments for granulation.

[0014] The present invention is further configured such that the moving control component includes a suspension frame, a fourth electric push rod is provided on the suspension frame, an elastic connector is provided at the output end of the fourth electric push rod, and the grinding block is provided at the output end of the fourth electric push rod through the elastic connector. When the fourth motor is started, the elastic connector is controlled by the fourth motor to drive the grinding block to move, so that the grinding block can fit against the surface of the cutting blade, thereby grinding and scraping the surface of the cutting blade. In this way, the sharpness of the cutting blade can be guaranteed when performing granulation cutting, and at the same time, the situation of plastic debris adhering to the cutting blade during granulation cutting can be avoided, keeping the cutting blade clean.

[0015] The present invention is further configured such that the elastic connector includes a connecting plate and a mounting plate, and a spring is provided between the connecting plate and the mounting plate. The connecting plate is located at the output end of the fourth electric push rod, and the grinding block is mounted on the mounting plate. Through the cooperation of the mounting plate, the spring, and the connecting plate, the grinding block can be elastically mounted at the output end of the fourth electric push rod. In this way, when the grinding block scrapes and grinds the surface of the cutting blade, automatic adjustment can be achieved, avoiding jamming between the cutting blade and the grinding block. Here, a pressure gauge can be installed between the grinding block and the mounting plate as needed to monitor the grinding pressure of the grinding block on the cutting blade and improve the accuracy of operation.

[0016] The present invention is further provided that a limiting telescopic rod is provided between the mounting plate and the connecting plate in cooperation with a spring. The setting of the limiting telescopic rod can improve the connection stability between the mounting plate and the connecting plate, overcome the torsional force generated by the spring caused by the weight of the mounting plate and the grinding block, and improve the stability of the grinding block during use.

[0017] The present invention is further configured such that the screening structure includes a screen, the screen is disposed in a collection box, a vibration motor is disposed at the bottom end of the screen, a cleaning port is disposed on the side wall of the collection box in conjunction with the screen, and a sealing door is disposed at the cleaning port. After the cutting and granulation are completed, the plastic granules will fall into the collection box before being used in the production and processing of automotive decorative parts. Among them, the granules that meet the conditions can pass through the screen and fall downward, while the granules that are not cut thoroughly and stick together will be intercepted on the screen, thereby realizing the screening of granules after granulation and improving the granulation accuracy.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, this utility model provides a granulator for automotive decorative parts, which has the following beneficial effects:

[0020] 1. This utility model features grinding blocks on both sides of the cutting blade. During use, when the cutting blade rises after cutting, the fourth electric push rod moves the elastic connector, which in turn moves the grinding blocks. This allows the grinding blocks to adhere to the surface of the cutting blade, grinding the blade edge and preventing the blade from becoming less sharp due to prolonged cutting, thus affecting the cutting effect. Simultaneously, the grinding blocks also scrape and clean the surface of the cutting blade, preventing debris generated during granulation from adhering to the blade surface.

[0021] 2. This utility model provides a lower scraper seat behind the conveying assembly, and an upper scraper seat above the lower scraper seat. A second electric push rod is provided on the upper scraper seat. Activating the second electric push rod controls the movement of the upper scraper seat to fit together with the lower scraper seat. Both the upper and lower scraper seats have conveying grooves that match the plastic strips used for granulation and cutting. In this way, when the upper and lower scraper seats are fitted together, the plastic strips used for granulation and cutting can be wrapped in the conveying grooves, and water stains on their surface can be scraped off, reducing the amount of water stains on the surface of the granules during granulation and cutting. Preferably, the surface of the conveying groove is smooth to reduce conveying resistance.

[0022] 3. This utility model has a collection box in front of the cutting table, and a screening structure inside the collection box. The bottom of the collection box is equipped with a discharge pipe. The screening component includes a screen, a vibrating motor, a cleaning port, and a sealing door that cooperate with each other. After cutting and granulation, the plastic granules will fall into the collection box before being used in the production and processing of automotive decorative parts. Particles that meet the conditions can pass through the screen and fall downwards, while particles that are not cut thoroughly and stick together will be intercepted on the screen, thereby realizing the screening of granules after granulation and improving the granulation accuracy.
