Description

Technical Field

[0001] This application belongs to the field of sheet metal processing equipment, and more specifically, relates to a sliding step for an auxiliary hot press plate. Background Technology

[0002] In the production process of plywood, the assembled slabs need to be hot-pressed and glued under certain temperature and pressure to form plywood with a certain strength and dimensional stability. See Chinese Patent Publication No. CN120307398A, which discloses a hot-pressing device and temperature control method with a temperature control structure, and specifically discloses the following technical content: including a frame, with hot-pressing plates evenly arranged inside the frame. This invention features a temperature control mechanism at the end of the frame. During the heating process, the mechanism controls the movement of the piston based on the temperature difference and air pressure changes at both ends of the first hollow tube. This increases the opening size of the manifold, improves the steam intake, and rapidly heats the hot press plate. After heating is complete, the temperature difference between the two ends of the first hollow tube decreases, the air pressure stabilizes, and the spring controls the piston to return to its original position, allowing for stable air intake through the manifold. Furthermore, when the steam discharge from the manifold is too high, the deformation of the bimetallic strip controls the baffle to move towards the inside of the manifold, reducing the air intake and preventing overheating. This allows the device to automatically adjust the temperature during use, improving its functionality and ensuring the quality and speed of hot pressing.

[0003] Referring to Chinese Patent Publication No. CN119175758A, a hot press for wood processing is disclosed, specifically including the following technical content: A column has a groove on its outer surface, a slider is slidably connected within the groove, one end of the slider is fixedly connected to a platform, both sides of the platform are fixedly connected to latches, the outer surface of the latches is fixedly connected to a chain, the chain meshes with a sprocket, the center of the sprocket is fixedly connected to a transmission rod, one end of the transmission rod is provided with a support plate, and a reduction motor is installed on the outer surface of the support plate. This invention uses an electromagnetic valve to transport steam from the pressing plate to an exhaust pipe, which then enters a spiral tube through a collection pipe. The residual heat steam in the spiral tube exchanges heat with cold water, thoroughly cooling the steam. The cold water is heated to a certain temperature and then transported back to the steam generator through a bend pipe. The thoroughly cooled gas is discharged from the bottom of the spiral tube, thus utilizing the residual heat of the steam to reduce the energy consumption of the steam generator.

[0004] In other words, existing hot presses used for sheet metal production all consist of multiple layers of hot press plates, which, with the assistance of hydraulic devices, perform hot pressing operations on the sheets. However, how to achieve stable linkage of the multiple layers of hot press plates, reduce the complexity of the hot press plate linkage mechanism, and mitigate the excessively high costs caused by this complexity has not been explored. Therefore, the applicant focuses on providing a sliding step for the auxiliary hot press plate to solve the above problems. Summary of the Invention

One end of an auxiliary step plate C7 is also disposed on the guide limiting blocks C8 between the two ends of the middle auxiliary step plate 9 and the hot press plate 14. A plate spacer 12 is disposed between the auxiliary step plate C7 and the middle auxiliary step plate 9.

[0023] The auxiliary step plate C7 has a guide limiting block B6 slidably disposed at one end away from the middle auxiliary step plate 9, and the guide limiting block B6 is fixedly connected to the side of the corresponding hot press plate 14; the guide limiting block B6 also has one end of an auxiliary step plate B5 disposed at the position between the corresponding hot press plate 14 and the auxiliary step plate C7, and the auxiliary step plate B5 is slidably disposed with the guide limiting block B6; a plate spacer 12 is also disposed at the guide limiting block B6 between the auxiliary step plate C7 and the auxiliary step plate B5.

[0024] The other end of the auxiliary step plate B5 is slidably disposed with the guide limiting block A4, which is fixedly disposed on the side of the corresponding hot press plate 14. One end of the auxiliary step plate A3 is disposed at the position between the hot press plate 14 and the auxiliary step plate B5 corresponding to the guide limiting block A4, and a plate spacer 12 is disposed at the guide limiting block A4 between the auxiliary step plate A3 and the auxiliary step plate B5.

[0025] One end of the auxiliary step plate A3 is provided with a hanging plate guide block 2 at the connection position with the top seat 17. The hanging plate guide block 2 is slidably connected to the auxiliary step plate A3. The hanging plate guide block 2 is located in the upper hanging plate 1 and is fixedly connected to the top seat 17.

[0026] The auxiliary step plate A3 located below the sliding step is fixedly connected to the corresponding hot press plate 14 via the bottom guide limit block 10 and the bottom fixing block 11. The auxiliary step plate A3 at this position is slidably set with the bottom guide limit block 10, and the bottom guide limit block 10 is fixedly connected with the hot press plate 14.

[0027] Example 2

[0028] See Figures 1 to 5 And please refer to Figure 4 The sliding steps of the auxiliary hot press plate are arranged in multiple sets in the height direction, and the sliding steps of adjacent sets are staggered and connected in the horizontal direction. That is, the auxiliary step plate A3 at the bottom of the upper sliding step and the upper hanging plate 1 in the lower sliding step are located on the side of the same hot press plate 14.

[0029] The structure and connection relationships of the remaining parts are the same as those described in the foregoing embodiments. Those skilled in the art can understand the technical content described in this embodiment based on the foregoing embodiments.

[0030] Based on the above embodiments, the following paragraphs will continue to describe in detail the technical features involved and the functions and roles of these technical features in this technical solution, so as to help those skilled in the art to fully understand the technical solution and reproduce it.

[0031] In this application, the auxiliary step plate A3, auxiliary step plate B5, auxiliary step plate C7, and middle auxiliary step plate 9 are all long rectangular plates 15. Each rectangular plate 15 has a rectangular through hole 16 machined in the length direction at the middle position. The hanging plate guide block 2, guide limiting block A4, guide limiting block B6, and guide limiting block C8 are all located in the rectangular through hole 16 and slide relative to each other along the rectangular through hole 16.

[0032] In this application, among the hanging plate guide block 2, guide limiting block A4, guide limiting block B6, and guide limiting block C8, the length of guide limiting block C8 is greater than the length of guide limiting block B6, the length of guide limiting block B6 is greater than the length of guide limiting block A4, and the length of guide limiting block A4 is greater than the length of hanging plate guide block 2.

[0033] In this application, the lifting cylinder assembly 18 can apply an upward force to the bottom hot press plate 14. The upward movement distance of the hot press plate 14 is limited by the rectangular through hole 16 of the rectangular plate 15 at that position. When the bottom hot press plate 14 moves upward to push the upper hot press plate 14 to move together, it can realize the clamping and pressure of the plates between adjacent hot press plates 14. The hot press plates 14 sequentially reduce the distance between adjacent plates and apply pressure to adjacent plates from bottom to top until they cooperate with the top seat 17 to achieve overall plate pressure. During the reset process, under the action of the sliding steps, the vertically distributed hot press plates 14 are restored to their initial positions and distances from each other from top to bottom.

Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
