TECHNICAL FIELD
[0001] The utility model relates to the technical field of decorative plate production, and specifically relates to a porcelain enamel decorative plate composite layer hot-pressing laminating device. BACKGROUND
[0002] With the rapid development of building decoration, home decoration and other industries, people's requirements for the aesthetic, durability and functionality of decorative materials are increasing. As a material integrating decoration and protection performance, porcelain enamel decorative plate has been widely used in many fields such as indoor and outdoor wall decoration, kitchen and bathroom facility surface covering, and public facility decoration, due to its smooth surface, bright color, wear resistance, corrosion resistance and many other advantages.
[0003] The traditional porcelain enamel decorative plate production process has many problems in the composite layer laminating link. In the early stage, manual glue coating and simple pressing after natural air drying were mostly used. This method not only has extremely low production efficiency and is difficult to meet the needs of large-scale industrial production, but also causes uneven glue coating due to the instability of manual operation, which easily causes the composite layers to not be tightly laminated and causes defects such as bubbles and gaps, seriously affecting the quality of the porcelain enamel decorative plate and reducing the product yield.
[0004] Subsequently, some enterprises introduced simple mechanical pressing equipment. Some existing hot-pressing laminating devices will cause wear of mechanical parts such as guide columns and sliding blocks after long-term use, which increases the fitting clearance and causes shaking or deviation during pressing. These will cause deviation of the pressure during transmission, uneven pressure, uneven heating of the hot-pressing plate, and obvious differences in the hot-pressing effect of the product. Therefore, the porcelain enamel decorative plate composite layer hot-pressing laminating device is proposed to solve the above problems. UTILITY MODEL CONTENTS

[0025] Further, the assembly groove 401 is provided in control assembly 4, the assembly groove 401 is opened in the bottom of upper die plate 202, the hot-pressing plate 3 is placed in the assembly groove 401, the hot-pressing plate 3 is slidably connected with the inner wall of the assembly groove 401, a plurality of oil cylinders 402 are built in the assembly groove 401, the plurality of oil cylinders 402 are evenly distributed in the bottom of the inner cavity of the assembly groove 401, one end of the oil cylinder 402 is fixedly connected with the bottom of the inner cavity of the assembly groove 401, the end of the oil cylinder 402 close to the upper die plate 202 is fixedly connected with the connecting pipe 403, the moving seat 404 is built in the oil cylinder 402, the moving seat 404 is slidably connected with the inner wall of the oil cylinder 402, the fixed ring groove 405 is opened around the moving seat 404, the sealing ring 406 is sleeved in the fixed ring groove 405, the outer ring wall of the sealing ring 406 is in contact with the inner wall of the oil cylinder 402, and the sealing ring 406 prevents oil leakage during the movement of the moving seat 404, to ensure the accuracy of pressure control in the oil cylinder 402.
[0026] Further, the moving roller 407 is fixedly connected to the moving seat 404 away from the upper mold plate 202, and the oil cylinder 402 is fixedly connected to the closing plate 408 away from the upper mold plate 202. The middle part of the closing plate 408 is provided with a communication window 409, and the end of the moving roller 407 away from the moving seat 404 extends into the assembly groove 401 through the communication window 409. The end of the moving roller 407 away from the upper mold plate 202 is fixedly connected to the pressure sensor 410, and the input end of the pressure sensor 410 is fixedly connected to the hot pressing plate 3. As the upper mold plate 202 moves downward, the hot pressing plate 3 contacts the enamel decorative plate composite layer and starts to apply pressure. Due to the unevenness of the surface of the composite layer, the reaction force received by each part of the hot pressing plate 3 is not uniform. The pressure change of each part of the hot pressing plate 3 is transmitted by the pressure sensor 410. Each pressure sensor 410 feeds back the detected pressure value to the control unit 101
[0027] The control unit 101 analyzes and judges according to the received pressure data. If the pressure of a certain point deviates from the preset average pressure value, the control unit 101 adjusts the oil pressure in the corresponding oil cylinder 402. When the pressure sensor 410 at a certain point detects a lower pressure, the control unit 101 injects oil into the corresponding oil cylinder 402 through the connecting pipe 403, the oil pushes the moving seat 404 to move away from the upper mold plate 202, and the moving seat 404 drives the moving roller 407 and the pressure sensor 410, thereby increasing the pressure at that point of the hot pressing plate 3; on the contrary, if the pressure at a certain point is too high, the control unit 101 will make the oil in the oil cylinder 402 flow out, thereby reducing the pressure at that point.
[0028] When the pressure of each point reaches the preset uniform pressure value and remains for a period of time, the hot pressing process is completed. The control unit 101 issues an instruction, and the telescopic cylinder 201 retracts, driving the upper mold plate 202 to move upward and separate from the lower mold plate 203, so that the operator can take out the hot-pressed enamel decorative plate composite layer.
[0029] Through the multi-point pressure equalization design, the pressure of each point of the hot pressing plate 3 can be monitored in real time, and timely adjustment can be made according to the feedback to ensure that the hot pressing plate 3 is uniformly stressed during the entire hot pressing process. This effectively avoids defects such as loose fitting, bubbles, and gaps in the composite layer caused by uneven pressure, improves the fitting quality and overall performance of the enamel decorative plate, and better adapts to different thicknesses and materials of the enamel decorative plate composite layer compared to traditional hot pressing fitting devices, ensuring the stability and consistency of product quality.
[0030] The uniform pressure distribution makes the contact between the hot press plate 3 and the composite layer of the enamel decorative plate more close and uniform, and the heat can be more effectively transferred from the hot press plate 3 to each part of the composite layer, avoiding the abnormal heat transfer caused by uneven pressure. This helps to improve the softening and fusion effect of the composite layer during the hot pressing process, further improving the bonding quality. Since the uniformity of pressure and heat transfer is improved, the product defects caused by uneven pressure and abnormal heat transfer, such as warping, deformation, delamination, etc. are reduced, thereby significantly improving the yield of the enamel decorative plate and reducing the production cost. The device can flexibly adjust the preset pressure value and the precision of pressure equalization through the control unit 101 to adapt to different production processes and product requirements. Whether it is large-scale industrial production or small-batch customized production, it can provide stable and reliable hot pressing bonding effect.
[0031] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Therefore, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application also intends to include these modifications and variations.
