[0016] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the contents of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to the application.

[0017] See also Figure 1 , Figure 2 and Figure 3This is a schematic diagram of the structure of this patent, a self-lifting feeding device for a hot press, including a hot press body 1, a mounting plate 4 and a cylinder 11. A pressing table 2 is provided on the hot press body 1, a pressing plate 3 is installed at the bottom end of the hydraulic cylinder piston rod of the hot press body 1, a screw motor 5 is fixedly installed at the bottom of the mounting plate 4, a screw 6 is fixedly installed at the bottom end of the rotating shaft of the screw motor 5, a limiting rod 7 is fixedly installed on the right side of the bottom of the mounting plate 4, a feeding frame 8 is provided on the right side of the hot press body 1, a nut 9 is fixedly installed at the bottom of the front end of the feeding frame 8, the nut 9 is screwed on the screw 6, a limiting ring 10 is fixedly installed at the bottom of the front end of the feeding frame 8, the inner side wall of the limiting ring 10 is slidably installed on the side wall of the limiting rod 7, and the cylinder 11 is located on the right side of the feeding frame 8.

[0018] The mounting plate 4 can be fixed to the indoor ceiling by bolts.

[0019] The feeding frame 8 is composed of two upper and lower plates and four uprights. Figure 1 A plurality of stacked plywood sheets are placed on the lower plate body.

[0020] The cylinder 11 can be fixed on the ground via a cylinder seat (not shown in the figure).

[0021] Specifically, the limiting ring 10 includes a ring body 12, the rear end of the outer wall of the ring body 12 is fixedly installed on the front end bottom of the loading frame 8, the four ends of the inner wall of the ring body 12 are provided with mounting grooves 13, the inner wall of the mounting groove 13 is fixedly installed with a fixing rod 14, the side wall of the fixing rod 14 is fixedly installed with a bearing 15, the outer wall of the outer ring of the bearing 15 is fixedly installed with a limiting wheel 16, the side wall of the limiting rod 7 is provided with a wheel groove 17, and the limiting wheel 16 is rollingly installed in the wheel groove 17.

[0022] The traditional screw limiter is achieved by sliding the slider in the slide groove, or by sliding the ring on the rod body. At this time, the limit is a sliding limiter, the friction is large, and the service life is short. If the limit wheel 16 is rolled and installed in the wheel groove 17, the limit is a rolling limiter, the friction is small, and the service life is long.

[0023] Specifically, the fixing rod 14 includes a rod body 18, and square grooves 19 are provided at both ends of the rod body 18. A spring 20 is fixedly installed in the square groove 19, and a square rod 21 is fixedly installed at the outer end of the spring 20. Slots are provided at both ends of the inner wall of the installation groove 13, and the square rod 21 is inserted into the slots.

[0024] Figure 3 The middle spring 20 is in a compressed state, and the square rod 21 is inserted into the slot in the installation groove 13 by the compression elasticity of the spring 20 , which facilitates the early assembly of the fixing rod 14 and the ring body 12 .

[0025] Specifically, a placement groove 22 is provided on the top of the pressing platform 2, and the left end of the placement groove 22 is in an open state.

[0026] Figure 1 In the figure, the bottom side of the right end of the plywood is attached to the right wall of the placement groove 22, and the front and rear ends of the plywood are respectively attached to the front and rear walls of the placement groove 22, so as to limit the placement position of the plywood. By opening the left end of the placement groove 22, it is convenient to push the plywood in the placement groove 22 onto the conveyor belt 23 through the plywood to be pressed.

[0027] Specifically, a conveyor belt 23 is provided on the left side of the hot press body 1 .

[0028] Specifically, the four corners of the pressing plate 3 are integrally formed with a slip ring 24 , and the slip ring 24 is slidably mounted on a support column of the hot press body 1 .

[0029] The provision of the slip ring 24 can increase the consistency of various positions of the pressing plate 3 , and prevent the four sides of the pressing plate 3 from being deformed by force when the pressing plate 3 presses down the plywood, so as to improve the anti-deformation strength of the pressing plate 3 .

[0030] Working principle: The hydraulic cylinder drives the circular plate 3 to press down the plywood in the placement groove 22 for hot pressing. After completion, the piston rod controlled by the cylinder 11 extends to drive the uppermost plywood in the feeding frame 8 to move to the left. Through this plywood, the plywood that has been pressed is moved to the left and pushed onto the conveyor belt 23. The plywood in the feeding frame 8 is moved to the pressing table 2 and the position is calibrated before repeating the pressing operation. Then, the screw motor 5 can be used to drive the screw 6 to rotate, driving the nut 9 and the feeding frame 8 to move upward until the uppermost plywood is located on the left side of the cylinder 11.

[0031] After the plywood in the loading frame 8 is used up, the stacked plywood to be pressed can be moved into the loading frame 8 by a forklift.

[0032] It should be noted that the equipment structure and drawings of this patent mainly describe the principles of this patent. In terms of the technology of this design principle, the settings of the device's power mechanism, power supply system and control system are not fully described. However, on the premise that technical personnel in this field understand the principles of the above patent, they can clearly know the details of its power mechanism, power supply system and control system.

[0033] This patent provides a feeding frame on the right side of the hot press body, and multiple plywoods are stacked on the feeding frame. The feeding frame is controlled to move up and down by a screw motor, and a cylinder is provided on the right side of the feeding frame. The plywood in the feeding frame can be pushed onto the pressing table on the hot press body by the cylinder, and the feeding frame can be controlled to move upward by the screw motor to change the height of the plywood. Through the above structure, there is no need for manual loading, which can greatly reduce labor intensity and improve work efficiency.
