[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 The pressing plate mechanism of the folding machine in this embodiment includes a hydraulic cylinder 1 and a pressing plate body 2, and a connecting member 3 is provided between the hydraulic cylinder 1 and the pressing plate body 2.

[0022] The pressure plate mechanism is an important component in the folding machine that is responsible for applying pressure to the material to complete the folding work. It is usually composed of a force source device and a force transmission structure. The power is transmitted to the force transmission structure through the force source device to firmly fix the workpiece on the workbench for folding operations. When the pressure plate mechanism is in use, the hydraulic cylinder 1 drives the pressure plate body 2 to move downward to fix the workpiece. Due to the inevitable friction between the pressure plate body 2 and the workpiece during long-term use, which will cause wear of the pressure plate body 2, in order to improve the folding quality, a connecting piece 3 is set to achieve quick installation and disassembly between the hydraulic cylinder 1 and the pressure plate body 2.

[0023] The connecting member 3 includes a shell 301, the shell 301 is fixedly installed at the bottom of the hydraulic cylinder 1, a fixing rod 302 is fixedly installed between the left and right inner walls of the shell 301, L-shaped positioning rods 303 are movably installed at both ends of the outer surface of the fixing rod 302, a spring 304 fixedly installed between the two L-shaped positioning rods 303 is sleeved on the outer surface of the fixing rod 302, and a control rod 305 is fixedly installed on the front side of the two L-shaped positioning rods 303.

[0024] One end of the two control rods 305 extends to the outside of the housing 301. By operating the two control rods 305, the two L-shaped positioning rods 303 can move in relative and opposite directions under the contraction and expansion of the spring 1 304.

[0025] A positioning hole compatible with the two L-shaped positioning rods 303 is opened on the top of the pressure plate body 2. When the two L-shaped positioning rods 303 are inserted into or withdrawn from the two positioning holes, the pressure plate body 2 is fixed or separated from the shell 301, thereby realizing the installation and disassembly between the pressure plate body 2 and the hydraulic cylinder 1, thereby facilitating the replacement of the pressure plate body 2.

[0026] Two slide grooves are provided on the inner top wall of the shell 301, and sliders slidably connected to the slide grooves are fixedly installed on the tops of the two L-shaped positioning rods 303. By providing the slide grooves and sliders, the stability of the two L-shaped positioning rods 303 during movement is improved.

[0027] The locking mechanism 4 includes a mounting plate 401, the mounting plate 401 is fixedly mounted on the front side of the shell 301, locking rods 402 are inserted at both ends of the inside of the mounting plate 401, a top plate 403 is fixedly mounted between the tops of the two locking rods 402, a limiting plate 404 located on the outer surfaces of the two locking rods 402 is fixedly mounted on the front side of the shell 301, and the outer surfaces of the two locking rods 402 are both sleeved with springs 405 fixedly mounted between the bottom of the mounting plate 401 and the limiting plate 404.

[0028] The tops of the two control rods 305 are each provided with a locking hole matched with the locking rod 402 , and a handle is fixedly mounted on the top of the top plate 403 .

[0029] By moving the top plate 403 up and down, the two locking rods 402 are driven to move up and down. Under the contraction and expansion of the spring 2 405, the two locking rods 402 can be inserted into or withdrawn from the inside of the locking hole, thereby achieving the fixing and release of the two control rods 305. By fixing the two control rods 305, the stability of the connection between the pressure plate body 2 and the shell 301 can be improved, ensuring reliability during installation.

[0030] When implementing, follow these steps:

[0031] 1) When the pressing plate body 2 needs to be disassembled, the top plate 403 is first pulled downward by the handle, and the top plate 403 drives the two locking rods 402 to move upward and squeeze the spring 2 405, so that the two locking rods 402 withdraw from the inside of the two locking holes, thereby releasing the lock of the two L-shaped positioning rods 303;

[0032] 2) Then pull the two control rods 305 in opposite directions, and the two control rods 305 move in opposite directions on the surface of the fixed rod 302, squeezing the spring 1 304 until the two L-shaped positioning rods 303 exit the interior of the positioning opening, and then remove the pressing plate body 2 downward;

[0033] 3) Finally, install the replaced pressing plate body 2 at the bottom of the housing 301 according to the reverse steps above, insert the two L-shaped positioning rods 303 into the interior of the positioning opening, and insert the two locking rods 402 into the interior of the two locking holes.

[0034] To sum up, the pressure plate mechanism of the folding machine can realize the rapid installation and disassembly between the hydraulic cylinder 1 and the pressure plate body 2 by setting the connecting piece 3, thereby facilitating the replacement of the pressure plate body 2 and avoiding the folding quality being affected by the wear of the pressure plate body 2 under long-term use.

[0035] Furthermore, by providing the locking mechanism 4, the purpose of limiting the two control rods 305 can be achieved, preventing the two control rods 305 from accidentally moving, ensuring that the two L-shaped positioning rods 303 are stably located in the positioning openings, and improving reliability during installation.
