Description

Technical Field

[0001] The present invention relates to the technical field of sheet processing, and particularly to a homogeneous composite sheet pressing device and a sheet production line. Background Art

[0002] Composite sheets are a type of composite sheet formed by combining two or more materials. The composite material forming process is the foundation and condition for the development of the composite material industry. With the broadening of the application fields of composite materials, the composite material industry has developed rapidly. With the development and construction, the application fields of composite sheets are also increasingly widely used in building home decoration and all aspects of our lives. The composite sheet press is a commonly used composite sheet processing device at present, and its function is to form the stacked materials by applying pressure.

[0003] Existing pressing devices usually use hydraulic cylinders to lower the pressing plate to complete the pressing of composite sheets. However, due to the limited contact area between the piston rod of the hydraulic cylinder and the pressing plate, the force on the pressing plate is concentrated at the position of the piston rod, resulting in excessive force in the middle of the composite sheet and less force around it, which easily causes the phenomenon of the four sides of the composite sheet warping, leading to an increase in the unqualified rate of composite sheet pressing; moreover, during the pressing process of the composite sheet, components are also required on both sides to clamp and stabilize it to prevent the materials from错开适当防止复合板材在压合的过程中,材料错开,压合后的复合板材其外侧平整度较低。

[0004] In addition, after the existing composite sheets are pressed, they are usually sent to the production line for subsequent processing. In the traditional method, it is not convenient to automatically send the composite sheets to the production line after pressing, which reduces the production efficiency. Therefore, it is necessary to develop a homogeneous composite sheet pressing device and a composite sheet production line. Summary of the Invention

A limiting slider 308 is protruded from the bottom of the front and rear ends of the upper clamping plate 305. The limiting slider 308 is limitedly slidable in the vertical direction and is stuck in the groove of the limiting slot 307. It should be noted that the front and rear lengths of the upper clamping plate 305 and the lower clamping plate 304 are not greater than the front and rear lengths of the sides of the plate 700. Thereby, it is ensured that the lower clamping plate 304 and the upper clamping plate 305 can be against the two sides of the plate 700, and the vertical spring 306 is prevented from contacting the side of the plate 700; moreover, during the pressing process of the plate 700, when the pressing plate 201 touches the upper clamping plate 305, the vertical spring 306 is compressed accordingly, and after the pressing of the plate 700 is completed, there is still some compressed space for the vertical spring 306, that is, the upper clamping plate 305 descends with the compression of the vertical spring 306, and the upper clamping plate 305 will never hinder the pressing plate 201 from descending The plate 700 is pressed; and when the pressing plate 201 gradually presses the plate 700, 301 gradually moves, and drives the lower clamping plate 304 to clamp the left and right sides of the plate 700 through the transverse spring 303, until the plate 700 is pressed, the transverse spring 303 still has a compressed space to prevent the transverse spring 303 from being compressed and deformed. When the two cross bars 501 rotate at the same time, the two clamping plates 301 move toward each other through the external thread 503 and the screw hole 302, so as to clamp or release the plate 700;

[0063] Please refer again Figure 2 , Figure 4 , Fig. 9 and Fig.10, the pusher assembly 400 further includes a fixing plate 402 disposed at the top of the processing table 100 behind the push plate 401. Two movable cylinders 403 are provided on the rear side wall of the push plate 401. The movable cylinders 403 fit and slide through the front and rear side walls of the fixing plate 402. The rear view cross-section of the movable cylinder 403 is in the shape of a hollow "middle" character. The front and rear side walls of the fixing plate 402 are provided with second through holes 404 in the shape of a hollow "middle" character. The inner side of the second through hole 404 is slidably fitted with the outer side of the movable cylinder 403. Two fixing seats 405 are provided at the top of the processing table 100 behind the movable cylinders 403. A linkage rod 406 is rotatably provided on the side wall of the fixing seat 405. The rod bodies of the two linkage rods 406 are respectively screwed and driven with the inner sides of the two movable cylinders 403. The rear end of the rod body of each linkage rod 406 is provided with a third worm gear 407 that meshes with a third worm 517, and the two linkage rods 406 rotate in the same direction; when the follower rod 514 rotates, through the third worm 517 and the third worm gear 407, the two linkage rods 406 are driven to rotate simultaneously, so that the two movable cylinders 403 drive the push plate 401 to move back and forth. When the pressing plate 201 presses down the laminated plate 700, the push plate 401 moves backward and will not block the pressing plate 201. When the pressing plate 201 gradually rises, the push plate 401 gradually moves forward to realize pushing the laminated plate 700 forward.

[0064] Please refer to again Figure 1 and Figure 4 , a sheet production line: including a homogeneous composite sheet pressing device and a roller conveyor 600 provided on the front side of a homogeneous composite sheet pressing device. An inclined material guiding slope 601 is recessed and opened on the upper surface of the processing table 100 directly below the front of the sheet 700. The material guiding slope 601 is arranged with the front lower and the rear higher. The roller conveyor 600 includes a plurality of rotating rollers 602 for conveying the sheet 700, and the lower edge of the material guiding slope 601 is flush with the upper surface of the rollers 602 of the roller conveyor 600. The roller conveyor 600 includes baffles provided on the front and rear sides of the rollers 602. The baffles are not shown in the figure. The baffles can be provided on the upper surface of the body of the roller conveyor 600 at the front and rear sides of the rollers 602, and the height of the baffles is higher than the upper surface of the rollers 602 to prevent the sheet 700 from falling off the roller conveyor 600 during the transportation of the rollers 602. An opening is provided on one side of the baffle close to the material guiding slope 601 for the sheet 700 to slide along the material guiding slope 601 and the opening onto the rollers 602. After the push plate 401 pushes the sheet 700, the sheet 700 slides along the material guiding slope 601 and the opening onto the rollers 602, and then is conveyed by the rollers 602 for subsequent processing.

[0065] In the specific use process, the plate 700 to be pressed is placed on the top of the processing table 100 and below the pressing plate 201, and the servo forward and reverse motor 509 is started to drive the driving rod 506 to rotate, and the two cross bars 501 are rotated at the same time through the second worm 507 and the second worm gear 504. When the two cross bars 501 rotate at the same time, the four transmission rods 203 are driven to rotate through the first worm 502 and the first worm gear 204, so that the four lifting cylinders 202 drive the pressing plate 201 to gradually descend, so as to press the plate 700, so that the force on the four sides of the pressed plate 700 is relatively uniform, and the phenomenon of the plate 700 being warped around is reduced. At the same time, through the external thread 503 and the screw hole 302, the two clamping plates 301 are driven to move towards each other at the same time to clamp the plate 700, which is beneficial for the two sides to keep neat when pressing, and further improves the flatness of the two sides of the plate 700.

[0066] After the sheet 700 is pressed, the servo forward and reverse motor 509 is started again, and its output shaft rotates in the opposite direction, which can drive the pressing plate 201 to gradually rise, and the two clamping plates 301 gradually release the sheet 700. At the same time, the push plate 401 gradually moves forward to push the sheet 700 forward. The sheet 700 slides along the material guide slope 601 and the opening to the roller 602, and then is transported by the roller 602 for later processing.
