Abstract
Description
Technical Field
[0001] The present application relates to the technical field of plate pressing, and in particular to a pressing machine. Background Art
[0002] In the laminating unit, the pallet is a crucial accessory for both the hot and cold presses. It carries and transports PP materials and products throughout the entire process. The pallet's dimensions are related to the hot platen, and its thickness depends on the weight of the PP material it carries, typically ranging from 8 to 10 mm. It must possess sufficient hardness, rigidity, and wear resistance, and its entire surface must not deform. A pallet is required for each opening in the press, and the number of openings in a press typically ranges from 4 to 24.
[0003] PP materials are stacked on pallets through the reflow line, and the pallets and PP materials are transported to the laminating machine station by the loader and unloader. The pushing mechanism on the loader and unloader then sends the pallet to the hot plate of the laminating machine. The loader and unloader leave the station, and the hydraulic system starts working. The plunger pushes the hot plate, pallet, and PP material to rise synchronously, and the opening gradually closes. After closing, the hydraulic system generates pressure to press the product. The core component of the hot plate laminating machine is the PP material that runs onto it. During the process of the pushing mechanism sending the pallet to the hot plate of the laminating machine, the PP material often scratches the surface of the hot plate, resulting in a shorter service life of the hot plate. The hot plate often needs to be replaced after a period of use, resulting in high replacement costs. Summary of the Invention

[0031] In the laminating unit, the pallet is a crucial accessory for both the hot and cold presses. It carries and transports PP materials and products throughout the entire process. The pallet's dimensions are related to the hot platen, and its thickness depends on the weight of the PP material it carries, typically ranging from 8 to 10 mm. It must possess sufficient hardness, rigidity, and wear resistance, and its entire surface must not deform. A pallet is required for each opening in the press, and the number of openings in a press typically ranges from 4 to 24.
[0032] PP materials are stacked on pallets through the reflow line, and the pallets and PP materials are transported to the laminating machine station by the loader and unloader. The pushing mechanism on the loader and unloader then sends the pallet to the hot plate of the laminating machine. The loader and unloader leave the station, and the hydraulic system starts working. The plunger pushes the hot plate, pallet, and PP material to rise synchronously, and the opening gradually closes. After closing, the hydraulic system generates pressure to press the product. The core component of the hot plate laminating machine is the PP material that runs onto it. During the process of the pushing mechanism sending the pallet to the hot plate of the laminating machine, the PP material often scratches the surface of the hot plate, resulting in a shorter service life of the hot plate. The hot plate often needs to be replaced after a period of use, resulting in high replacement costs.
[0033] Reference Figure 1 、 Figure 2 The present application provides a laminating machine, including a machine body 100 , a cylinder assembly 200 , a movable pad 300 , a fixed pad 400 , a hot plate 500 , a rolling device 600 and a tray 700 .
[0034] A pressing space 110 is provided inside the machine body 100, and the pressing space 110 forms an opening on one side of the machine body 100. The oil cylinder assembly 200 is mounted on the machine body 100. The oil cylinder assembly 200 includes a cylinder body 210 and a plunger 220 provided in the cylinder body 210. The movable pad 300 is located inside the pressing space 110. The movable pad 300 is fixedly connected to the plunger 220. The fixed pad 400 is fixed inside the pressing space 110. Along the movement direction of the plunger 220, the fixed pad 400 is aligned with the movable pad 300 in the pressing space 110. The hot plate 500 is provided in the pressing space 110 and is located between the fixed pad 400 and the movable pad A plurality of hot plates 500 are arranged between the pads 300, and each hot plate 500 is arranged at intervals along the moving direction of the plunger 220. Both sides of the hot plate 500 slide with the body 100, and the hot plate 500 has an inlet and outlet end exposed from the open side of the body 100. The upper surface of the hot plate 500 is a receiving surface, and the receiving surface is covered with a protective plate. The rolling device 600 includes a mounting seat 610 and a rolling member 620. The rolling member 620 is fixed to the inlet and outlet end of the hot plate 500 through the mounting seat 610, and the rolling member 620 is higher than the receiving surface of the hot plate 500. The tray 700 is used to support materials, and the tray 700 is used to feed the hot plate 500 from the inlet and outlet end.
[0035] During operation, the material is stacked onto the pallet 700 through the reflow line, and then the pallet 700 and the material are transported to the laminating machine station by the loader and unloader. The pushing mechanism on the loader and unloader then sends the pallet 700 onto the hot plate 500 of the laminating machine. The loader and unloader leave the station, and the cylinder assembly 200 starts working. The plunger 220 pushes the hot plate 500, the pallet 700, and the material to rise synchronously, generating pressure to press the product. During the feeding process of this laminating machine, the protective plate covering the receiving surface of the hot plate 500 can effectively block the sliding friction between the pallet 700 and the receiving surface of the hot plate 500 during feeding and unloading. In addition, because the rolling element 620 is higher than the receiving surface, the rolling element 620 will form a small elevation angle with the receiving surface. When the material enters the hot plate 500 from the feeding and unloading end, most of the sliding friction is converted into rolling friction through the rolling element 620. In this way, on the one hand, the protective plate effectively blocks the sliding friction between the tray 700 and the hot plate 500 during loading and unloading, and on the other hand, the rolling element 620 reduces the sliding friction between the protective plate and the tray 700, effectively alleviating the friction resistance, thereby effectively preventing the supporting surface of the hot plate 500 from being scratched and worn, thereby increasing the service life of the hot plate 500 and reducing the replacement cost of the hot plate 500.
[0036] In some embodiments, a lower surface of the end of the tray 700 is provided with a limiting groove for corresponding to the rolling element 620, and the depth of the limiting groove is greater than or equal to the height of the rolling element 620 above the supporting surface.
[0037] When the tray 700 is delivered to the hot plate 500, the rolling member 620 is inserted into the limiting groove at the end of the tray 700, so that the lower surface of the tray 700 and the protective plate on the supporting surface of the hot plate 500 remain level, and the tray 700 is not supported by the rolling member 620. This structural arrangement can prevent the rolling device 600 from being damaged during repeated pressing processes.
[0038] In some embodiments, guide rails extending along the direction of movement of the plunger 220 are provided on both sides of the press space 110. The two sides of the hot plate 500 engage with the guide rails via first sliders, while the two ends of the movable pad 300 engage with the guide rails via second sliders. When the plunger 220 pushes the movable pad 300 to move, the movable pad 300 can only move up and down along the direction of the guide rails, ensuring stable lifting and lowering of the movable pad 300 and the hot plate 500.
[0039] In some embodiments, a plurality of rolling devices 600 are provided, and each rolling device 600 is arranged at intervals along the width direction of the hot plate 500. The plurality of rolling devices 600 work together to make the tray 700 more stable when entering the hot plate 500.
[0040] In the embodiment shown in this application, two rolling devices 600 are provided.
[0041] In some embodiments, the rolling element 620 is a roller. Accordingly, the limiting groove on the lower surface of the tray 700 is a U-shaped groove structure.
[0042] Of course, the rolling element 620 can also be configured as a spherical ball. Accordingly, the limiting groove on the lower surface of the tray 700 is a hemispherical groove structure.
[0043] In some embodiments, the rolling element 620 is 4 to 5 mm higher than the protection plate.
[0044] In the present application, the wheel surface of the roller is 4 to 5 mm higher than the protection plate.
[0045] In some embodiments, the protective plate is a 304 stainless steel plate.
