Description

Technical Field

[0001] This invention relates to the field of leather processing equipment technology, and in particular to a leather processing equipment and processing method. Background Technology

[0002] With the rapid development of the automotive, home furnishing, and office furniture industries, the market has placed increasingly higher demands on the appearance, texture, performance, production efficiency, and environmental friendliness of seat cushions. Traditional seat cushion production generally uses a leather covering process, which requires dozens of steps, including base molding, leather cutting, sewing, covering, and nailing. This process is highly dependent on manual operation and has inherent defects such as low production efficiency, high labor costs, easy cracking and wear at product seams, poor appearance consistency, and low yield. Summary of the Invention

[0003] The purpose of this invention is to provide a leather processing equipment and method. It adopts a modular design, integrating core processes such as mold cleaning, release agent spraying, raw material injection, mold preheating, and constant-temperature curing onto a single device. Furthermore, the cleaning mechanism, spraying mechanism, and injection mechanism can all be independently disassembled and replaced, adapting to processing molds of different sizes and patterns to meet the production needs of various products. The cleaning mechanism, release agent spraying mechanism, and raw material injection mechanism all employ a transmission structure, enabling precise displacement of the spray nozzle in the X, Y, and Z directions. This solves problems such as incomplete cleaning, uneven spraying, and injection deviation inherent in manual operation, thereby improving product yield.

[0013] A leather processing method includes the following steps: S1: The mold base and mold top cover of the processing mold are flipped and closed through the first connecting ear plate, and the locking and fixing are completed by the buckle of the second connecting ear plate. The positioning screw is turned to drive the positioning block to complete the locking and limiting. The sealing plug is embedded into the injection hole of the mold top cover to complete the cavity sealing. The processing mold is installed on the support base. At the same time, the incoming inspection, formulation ratio, mixing and homogenization and drying preheating treatment of the modified polymer raw materials are completed. The raw materials are sent to the raw material storage tank for constant temperature and standby. The water-based release agent is loaded into the release agent storage tank for standby. S2: Start the first servo motor, drive the first one-way lead screw to rotate, and drive the first slider sleeved on it to move horizontally along the first transverse slide frame. The processing mold is accurately transferred to the corresponding station of the cleaning mechanism at the rear of the equipment through the support seat. Stop the first servo motor to complete the station positioning. S3: Unscrew the positioning screw to release the locking limit, pry open the buckle to open the mold top cover, and start the second servo motor, third servo motor and fourth servo motor of the cleaning mechanism in sequence. Drive the second one-way screw, third one-way screw and fourth one-way screw to rotate respectively, drive the first nozzle to complete the vertical, horizontal and front and back multi-degree-of-freedom displacement, so that the first nozzle is aligned with the inside of the mold base cavity. Start the air pump, and the high-pressure airflow is delivered to the first nozzle through the first connecting pipe to perform all-round pulse high-pressure cleaning of the mold cavity, remove dust, impurities and residual materials inside the cavity. After cleaning is completed, all moving parts of the cleaning mechanism are reset. S4: Sequentially start the fifth, sixth, and seventh servo motors of the release agent spraying mechanism, which drive the fifth, sixth, and seventh one-way lead screws to rotate, thereby driving the second nozzle to complete multi-degree-of-freedom displacement, so that the second nozzle is aligned with the inner wall of the mold cavity. Start the feeding component of the release agent storage tank, and the release agent is delivered to the second nozzle through the second connecting pipe to uniformly atomize and spray the inner wall of the mold cavity. The spraying thickness is controlled within the preset process range. After the spraying is completed, all moving parts of the spraying mechanism are reset. S5: Close the top cover of the mold, and complete the locking and fixing through the buckle of the second connecting ear plate. Turn the positioning screw to drive the positioning block to complete the locking and limiting. Start the heater to heat the processing mold to the preset process temperature and close the loop constant temperature control to ensure that the temperature of each point in the mold cavity is uniform and the temperature difference is controlled within the preset accuracy range. S6: Move the handle to release the locking limit of the third connecting ear plate on the connecting rod, pull the vertical rod to drive the connecting rod and the pressure rod, and then drive the sealing plug to disengage from the injection hole. The eighth, ninth and tenth servo motors of the raw material injection mechanism are started in sequence, driving the eighth, ninth and tenth one-way screws to rotate respectively, driving the third nozzle to complete multi-degree-of-freedom displacement and accurately align with the injection hole. The material injection assembly of the raw material storage tank is started, and the preheated molten material is quantitatively injected into the mold cavity through the third connecting pipe and the third nozzle. After the injection is completed, the third nozzle is reset, and the sealing plug is re-embedded into the injection hole to complete the cavity sealing. The product is molded according to the preset process parameters of pressure holding, temperature control and time control, so that the product substrate and surface pattern and concave-convex three-dimensional structure are synchronously molded as one piece. S7: Start the heater. The heater continuously controls the temperature to complete the constant temperature curing and cross-linking of the product in the mold, eliminate internal stress, ensure product dimensional stability, and form a dense and wear-resistant layer on the surface. S8: After curing and shaping, start the first servo motor to drive the processing mold back to the initial loading position, turn the positioning screw to unlock the buckle, rotate around the first connecting ear plate to open the mold top cover, and take out the one-piece molded product; S9: Remove burrs and excess material from the removed products and perform fine edge trimming. Then, conduct preliminary inspections on the trimmed products in sequence, including surface texture, embossing effect, and gloss. Additionally, perform performance tests on wear resistance, compressive strength and resilience, weather resistance, and dimensional accuracy. Products that pass the tests are packaged and put into storage, while unqualified products are recycled.

[0014] Therefore, the present invention adopts the above-mentioned leather processing equipment and processing method, which adopts a modular design to integrate core processes such as mold cleaning, mold release agent spraying, raw material injection, mold preheating and constant temperature curing into the same equipment. Moreover, the cleaning mechanism, spraying mechanism and injection mechanism can be independently disassembled and replaced, which can be adapted to processing molds of different sizes and patterns to meet the production needs of various products. The cleaning mechanism, mold release agent spraying mechanism and raw material injection mechanism all adopt a transmission structure, which can realize the precise displacement of the nozzle in the X, Y and Z directions, solving the problems of incomplete cleaning, uneven spraying and injection deviation that exist in manual operation, and improving the product yield.
