Embodiment 1
[0045] see Figures 1 to 12 , a heat press machine lower plate seat with automatic level adjustment, including a horizontal base plate 1, two parallel chute 101 is provided on the top of the base plate 1, and a support seat 2 slidably connected with it is provided inside the chute 101 The top of the support seat 2 is provided with a drawing board 3 snapped thereto; the bottom end of the support seat 2 is provided with a plurality of roller grooves 201 along the length direction of the chute 101, and a roller 4 is arranged in the roller groove 201, Between the roller groove 201 and the roller 4, there is an axle sleeve 5 that slides up and down with the roller groove 201, and the roller 4 that moves up and down makes the drawing board 3 and the upper board fit better, ensuring the connection between the drawing board 3 and the upper board. Parallel to effectively prevent the 3 drawing boards from being unable to stick to the upper board after being heated and deformed, and avoi...
Embodiment 2
[0056] The difference between embodiment two and embodiment one is:
[0057] see Figure 4 , a cylinder 7 is arranged between the cover plate 203 and the shaft sleeve 5, the shaft extension end of the cylinder 7 is fixedly connected with the shaft sleeve 5, and the cylinder 7 has no air inlet and outlet ports. After the drawing board 3 is deformed, heat transfer The amount of compression of each cylinder 7 is proportional to the force of the drawing board 3 at the corresponding position, thereby compensating the deformation of the drawing board 3 so that the drawing board 3 can be in parallel contact with the upper board; the connection of the cylinders 7 is stable and reliable, and the compression of the gas has great A good cushioning effect ensures that the drawing board 3 will not be damaged by impact.
Embodiment 3
[0059] The difference between embodiment three and embodiment one is: see Figure 5, the bushing 5 is in sealing and sliding connection with the drum groove 201, and a separator 208 is fixed on the upper part of the roller groove 201; the separator 208 separates the roller groove 201 into an upper chamber 209 and a lower chamber 210; the partition A number of small holes 212 are also provided on the part 208 to communicate with the upper cavity 209 and the lower cavity 210; a second spring 211 is arranged in the lower cavity 210; ; The upper cavity 209 is filled with compressed inert gas, and the lower cavity 210 is filled with electrorheological fluid; the liquid level of the electrorheological fluid is at least higher than that of the small hole 212 under the static state when the heat press machine is stopped; An external circuit applies an electric field to the electrorheological fluid.
[0060] When the heat press machine is working, in the process of heat transfer, if t...
