Description

Technical Field

[0001] The present invention relates to the technical field of sewn covering parts, and particularly to a pre-covering and press-fitting structure for the skeleton and the face cover in the production of sewn covering parts. Background Art

[0002] In the production process of sewn covering parts, the press-fitting quality of the skeleton and the face cover directly affects the durability and aesthetics of the finished product. Traditional production processes mainly rely on mechanical press-fitting, bonding, or sewing to complete the combination of the skeleton and the face cover. However, with the continuous improvement of the requirements for product quality, production efficiency, and consistency in industries such as automotive interiors and furniture manufacturing, how to optimize the press-fitting process, improve the degree of automation, and reduce manual intervention has become the focus of industry attention. Therefore, for the press-fitting process of the skeleton and the face cover, different mechanized or automated production solutions have gradually emerged in the market to improve the overall production level.

[0003] The prior art mainly adopts the mechanical press-fitting method with a fixed press groove plate. After manually placing the face cover on the skeleton, the press-fitting device applies pressure to make the face cover fit the skeleton; usually, it relies on mechanical pressure or hot pressing technology to achieve bonding, and before press-fitting, manual placement and adjustment of the face cover are required to ensure its alignment. The feeding link usually involves manually transporting the face cover or using a simple conveying device to send the material into the press-fitting area. In some improved solutions, an adsorption device is introduced to assist in feeding, but most still rely on manual operation. In addition, the traditional press-fitting mechanism uses a press groove plate with a fixed specification, resulting in the need to replace the entire set of press-fitting molds or perform cumbersome adjustments when adapting to products of different specifications, which affects production efficiency.

[0004] Firstly, the design of the fixed press groove plate makes the equipment less adaptable, difficult to adapt to face covers and skeletons of different sizes, the process of replacing the mold is cumbersome, and the production adjustment is complex; secondly, the mechanical press-fitting method relies on fixed pressure, lacking fine adjustment for different face cover materials and shapes, which easily leads to uneven press-fitting, wrinkling or poor bonding, affecting product quality; thirdly, the existing feeding methods mainly rely on manual placement or simple mechanical conveying, with large positioning errors and low accuracy in placing the face cover, affecting the consistency of subsequent press-fitting, and thus reducing the product qualification rate. Therefore, a pre-covering and press-fitting structure for the skeleton and the face cover in the production of sewn covering parts is proposed to solve the above problems. Summary of the Invention

The present invention adopts the technical scheme of a grooving mechanism and a replaceable grooving plate, achieving the technical effects of improving the pressing accuracy of the face cover and the skeleton and enhancing the applicability of the equipment. Through the combined design of the first slide rail, the first slider and the second slider, the grooving plate can be quickly replaced according to the requirements of face covers of different specifications, thus ensuring the pressing accuracy and reducing the production adjustment time. Compared with the technical scheme of a fixed grooving plate in the prior art, this scheme overcomes the problems of single grooving plate specification and poor adaptability, solves the deficiencies of traditional equipment that need to frequently replace the whole set of equipment components, have high adjustment process complexity and low production efficiency when replacing face covers of different sizes, and at the same time reduces material waste and improves the consistency of pressing quality.

[0017] 2.

By providing a stable pressing force through the electric telescopic rod I and combining with the negative pressure adsorption technology, the pressing plate can avoid displacement while applying pressure to the vehicle skeleton, improving the consistency and bonding effect of pressing. The cooperation between the spring air pipe I and the negative pressure holes enables the vehicle skeleton to be quickly released after pressing, reducing manual intervention and improving the automation level. Compared with the prior art technical solution that simply relies on mechanical pressure for pressing, this solution effectively solves the problems of face cover wrinkling or insecure fitting caused by uneven pressure, and at the same time reduces the situation of face cover damage due to excessive pressure, improving the overall production stability and product qualification rate.

[0018] 3. The technical solution of the present invention adopts the feeding mechanism combined with the air nozzle and the silica gel air cushion, achieving the technical effects of high-precision conveying of the face cover material, improving the automation degree, and reducing manual intervention. By controlling the stable movement of the feeding mechanism through the slide rail II and the slider III, the electric telescopic rod II drives the air nozzle to adsorb the leather material, and the electric telescopic rod III cooperates with the silica gel air cushion to ensure that the face cover material is placed flat in the pressing groove plate, preventing material wrinkling or dislocation. Compared with the prior art technical solution that mainly relies on manual placement of the face cover, this solution overcomes the problems of large positioning errors, low production efficiency, and high manual operation intensity, realizes accurate feeding, improves the automation level and production consistency of the equipment, significantly reduces the production cost, and reduces the influence of human factors on the quality.

[0026] Working principle: First, select a suitable grooving plate 305, then place the grooving plate 305 with slider one 302 into the first slide rail 301, and then fix the grooving plate 305 through the cooperation of slider two 303 and bolt one 304. Select the corresponding pressing plate 4012, and then fix the first fixing plate 408 and the pressing plate 4012 through bolt two 4013. Then select the vehicle frame 4011 to be overlaid.

Subsequently, the second electric telescopic rod 804 drives the second fixing plate 803 to descend, so that the air nozzle 8010 at the bottom of the second fixing plate 803 sucks up the leather inside the material feeding trolley 10. Start the third slider 802, and the third slider 802 drives the second fixing plate 803 to move along the second slide rail 801 to send the leather to the upper side of the grooving plate 305. Then, the second electric telescopic rod 804 drives the second fixing plate 803 to descend again, so that the air nozzle 8010 stops sucking, and the leather is put down. In order to ensure that the leather can be placed flatly inside the grooving plate 305, start the third electric telescopic rod 805. The third electric telescopic rod 805 drives the silica gel air cushion 808 to press down on the leather, so that the leather is completely attached to the surface of the grooving plate 305. Subsequently, the third slider 802 drives the second fixing plate 803 back to the initial position to prepare for the transportation of the next piece of leather. Then, start the first electric telescopic rod 401. The first electric telescopic rod 401 drives the first fixing plate 408 to move downward through telescopic movement, so that the pressing plate 4012 at the bottom of the first fixing plate 408 presses downward, and the pressing plate 4012 drives the vehicle frame 4011 to apply pressure to the grooving plate 305 with leather placed on it, thereby realizing covering and pressing. After the pressing is completed, the first spring air pipe 4015 stops providing negative pressure, and the first electric telescopic rod 401 retracts upward.
