Description

Technical Field

[0001] The utility model relates to the technical field of pressing machines, in particular to a plate pressing machine capable of quickly adjusting pressure. Background Art

[0002] A plate pressing machine is an industrial device mainly used for pressing and processing plate materials such as wood, composite materials, plastics, etc. through the action of heating and pressure. Its function is to form an integrated plate product from raw materials through a hot pressing process at a certain temperature and pressure. This kind of equipment is usually used for producing furniture plates, building templates, floor materials, etc. An existing plate pressing machine (Publication No.: CN213413233U) exposes at least the following defects in use:

[0003] 1. The inability to quickly adjust the pressure means that when dealing with different materials or different process requirements, it is necessary to stop the machine to adjust the pressure. This will lead to pauses and increased waiting time in the production process, reducing production efficiency. Stopping the machine to adjust the pressure not only wastes time, but also may increase energy consumption and raw material loss, thus increasing production costs. Unstable pressure or untimely adjustment during the pressing process may lead to quality fluctuations of the product. Especially for products with high requirements for pressing pressure, such fluctuations may affect the uniformity of the product and the achievement of quality standards. Therefore, a plate pressing machine capable of quickly adjusting pressure is needed.

[0004] 2. The adhesion of the glue is greatly affected by temperature. If the temperature is not appropriate, the glue may not fully flow and penetrate the surface of the plate, resulting in insecure adhesion or uneven adhesion problems. The ineffective adhesion of the glue will affect the quality of the final product. This may cause the plate to be easily cracked and peeled during use, and even affect the appearance and service life of the product. If the glue fails to adhere effectively, remedial operations may be required, such as re-coating the glue or performing secondary pressing, which will increase the production cycle and cost and reduce production efficiency. Failure to reach the appropriate glue adhesion temperature may lead to waste of energy in the production process, such as additional heating time or the need for re-heating, and may also increase the waste rate of glue and plates. Therefore, a heatable plate pressing machine is needed.

[0005] 3. The immobility of the pressing machine may limit the layout flexibility of the factory or workshop. This may lead to an unreasonable layout of the production line, affecting the smoothness and efficiency of the work process. If it is necessary to rearrange the production line or adjust the process flow, a fixed pressing machine may require additional engineering adjustments or layout changes, while a mobile pressing machine can more conveniently adapt to these changes. A pressing machine fixed in one place may be more difficult to handle during maintenance and cleaning, especially when the surrounding space needs to be cleared or internal maintenance of the equipment is required. Therefore, a conveniently mobile plate pressing machine is needed. Summary of the Utility Model

[0025] Embodiment

[0026] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0027] A plate pressing machine capable of quickly adjusting pressure, comprising a support base 1, a friction support base 2 and brake universal wheels 3 are installed at the bottom of the support base 1, a workbench 4 is installed on the support base 1, an emergency stop installation box 5 is installed on the side of the workbench 4, a protective shell 6 is installed on the workbench 4, a safety grating 7 is installed on the side of the protective shell 6, an upper machine cover 15 and an installation rack 17 are installed on the top of the protective shell 6, a control panel 8 is installed on the upper machine cover 15, a hydraulic device 9 is installed on the installation rack 17, a hydraulic rod 10, a telescopic rod 11 and a pressing plate 12 are arranged under the hydraulic device 9, and a pressure sensor 13 is arranged on the pressing plate 12.

[0028] Specifically: A number of heating wires 14 are installed inside the workbench 4.

[0029] Specifically: A number of small windows 16 are provided on the protective shell 6 and the upper machine cover 15.

[0030] Specifically: The control panel 8 is connected to the hydraulic device 9 and the pressure sensor 13 through wires.

[0031] Specifically: The sensitive element of the pressure sensor 13 is installed at the lower part of the pressing plate 12.

[0032] In this embodiment, a control panel 8 is installed on the upper machine cover 15, a hydraulic device 9 is installed on the installation rack 17, a hydraulic rod 10, a telescopic rod 11 and a pressing plate 12 are arranged under the hydraulic device 9, a pressure sensor 13 is arranged on the pressing plate 12, the control panel 8 is connected to the hydraulic device 9 and the pressure sensor 13 through wires, and the sensitive element of the pressure sensor 13 is installed at the lower part of the pressing plate 12.

[0033] The realization of quickly adjusting pressure depends on the coordinated action of the control panel 8, the hydraulic device 9 and the pressure sensor 13. The control panel 8 monitors and adjusts the pressure output of the hydraulic system by connecting the hydraulic device 9 and the pressure sensor 13. The hydraulic device 9 can adjust the positions and force outputs of the hydraulic rod 10 and the telescopic rod 11 according to the instructions of the control panel 8, so as to precisely control the pressure exerted by the pressing plate 12 on the workpiece. The pressure sensor 13 measures and transmits the pressure data exerted by the pressing plate 12 in real time, ensuring the stability and high efficiency in the production process, while reducing costs and improving product quality. The pressure sensor 13 is the HWJ1 pressure sensor produced by Wuxi Sainuo Measurement and Control Technology Co., Ltd. This product uses piezoelectric film material as the sensitive element, has high sensitivity, large measurement range and wide frequency response range, and is suitable for the measurement of dynamic pressure. The product features a high natural frequency ≥400 kHz, a rise time <2 μs, and is transmitted by a long cable, with strong anti-interference ability.

[0034] Due to the ability to quickly adjust the pressure, operators can make rapid adjustments when dealing with different materials or different process requirements, reducing downtime and waiting time during the production process. This flexibility and rapid responsiveness significantly improve production efficiency. The time required for downtime to adjust the pressure is reduced, thereby lowering energy consumption and raw material losses. In addition, more precise pressure control can reduce the rejection rate of products, further lowering production costs. By ensuring the stability and accuracy of the pressure during the pressing process, the uniformity of the product and the achievement of quality standards are guaranteed. Especially for products that require high-precision pressing, this stability is particularly important, effectively avoiding quality fluctuations and the production of defective products. By precisely controlling the pressure, the safety risks that may be brought about by human operation errors are reduced, enhancing the safety of operators and the stability of the working environment. The precision and rapid responsiveness of pressure regulation help reduce unnecessary wear and damage to the equipment during operation, extending the service life of the equipment.

[0035] In this embodiment, a number of heating wires 14 are installed inside the workbench 4. Through heating, the glue can flow and penetrate the surface of the board better, ensuring uniform and firm adhesion, reducing the risk of cracking or peeling of the board during use, and enhancing the quality of the final product. The appropriate temperature enables the glue to quickly reach the optimal adhesion state, reducing waiting time and additional operation steps, thereby shortening the production cycle and improving production efficiency. Since the need for secondary gluing or repeated pressing is reduced, material and labor costs are saved. In addition, precise temperature control can avoid overheating, thus reducing energy waste. Ensuring the stability and consistency of each adhesion process, reducing the number of unqualified products, thereby reducing material waste and subsequent processing costs. Through the optimized adhesion effect, the final product is more stable in structure, has a longer service life, and can better meet quality requirements and customer expectations. The design of the built-in heating wire 14 allows operators to flexibly adjust the temperature settings according to different types of glue and board characteristics to achieve the best adhesion effect. The design of the built-in heating wire 14 can control the heating process more safely, avoiding the fire risks or operational inconveniences that may be brought about by traditional external heating methods.

[0036] In this embodiment, a friction support base 2 and a braking universal wheel 3 are installed at the bottom of the support base 1. Due to the installation of the friction support base 2 and the braking universal wheel 3, the operator can easily move the press to different working areas or positions. This is particularly useful when it is necessary to frequently change the production layout or move the machine to different work stations. The mobile design makes the press more flexible, allowing it to quickly adjust the layout according to production requirements, optimize the production process, or facilitate operation and storage in a limited space. The convenient mobility design makes it easier to clean and maintain the machine, as it is convenient to clean the surrounding area or perform routine maintenance work. By reducing the time for layout adjustment and machine movement, idle time on the production line can be saved, thus improving the overall production efficiency. The mobile design generally also means that the machine is more accessible and easier to operate, enabling the operator to more conveniently adjust the equipment settings or perform daily operations.

[0037] It should be noted that as a plate press capable of quickly adjusting the pressure, the present utility model can be quickly adjusted when dealing with different materials or different process requirements by installing a pressure sensor 13, reducing the downtime and waiting time during the production process; by installing a heating wire 14, the glue can flow and penetrate better onto the surface of the plate, ensuring uniform and firm adhesion, reducing the risk of cracking or peeling of the plate during use, and improving the quality of the final product; by installing a braking universal wheel 3, the press can be easily moved to different working areas or positions, making the press more flexible, capable of quickly adjusting the layout according to production requirements, optimizing the production process, or facilitating operation and storage in a limited space.
