Two groups of feeding mechanisms 4 are symmetrically distributed, and the feeding mechanism 4 includes: a fixed guiding mechanism, a movable guiding mechanism and an adjusting mechanism 5.

[0038] Furthermore, as Figure 1 shown, in this embodiment, two groups of fixed guiding mechanisms are spaced apart. The fixed guiding mechanism includes two fixed side plates 41 symmetrically fixed on the workbench 1 and a fixed roller 42 rotatably installed between the two fixed side plates 41. The movable guiding mechanism is located between the two groups of fixed guiding mechanisms. The movable guiding mechanism includes two symmetrically distributed movable side plates 43 and a movable roller 44 rotatably installed between the two movable side plates 43. The movable side plate 43 penetrates the workbench 1, and the adjusting mechanism 5 is drivingly connected to the movable side plate 43 for adjusting the height of the movable side plate 43. After adopting the above solution, during use, the film coil is fed by a dedicated feeding device and wound by a dedicated winding device. The upper heating die 3 is driven by a hydraulic cylinder to move in the vertical direction for mold closing and mold opening. During processing, the film is passed around the upper sides of the two fixed rollers 42 and under the movable roller 44. When the processing section of the film moves to the lower heating die 2, the hydraulic cylinder is started to move the upper heating die 3 downward for mold closing, and then the adjusting mechanism 5 is started to drive the movable side plate 43 downward, so that the movable roller 44 moves downward. The film is tightened by the cooperation of the movable roller 44 and the fixed roller 42 to make the film in a tensioned state. The film is heated and pressed into shape by the lower heating die 2 and the upper heating die 3.

[0039] It should be noted that both the lower heating die 2 and the upper heating die 3 adopt electric heating, which is a common heating method for hot pressing machines in the prior art and has been fully disclosed in the prior art, so it will not be elaborated too much in this article.

[0040] Optionally, as Figure 1 and Figure 2 shown, in this embodiment, the adjusting mechanism 5 includes: a cross beam 51 and a vertical cylinder 52. The cross beam 51 is fixed to the bottom end of the movable side plate 43, the vertical cylinder 52 is fixed to the bottom surface of the workbench 1, and the piston rod of the vertical cylinder 52 is fixedly connected to the cross beam 51. After adopting the above solution, during use, the vertical cylinder 52 is started, the cross beam 51 is driven to move by the piston rod of the vertical cylinder 52, and the movable side plate 43 is driven by the cross beam 51 to move in the vertical direction, so as to adjust the height of the movable roller 44.

[0041] Preferably, as Figure 1 and Figure 2 shown, in this embodiment, the adjusting mechanism 5 further includes: a guide post 53 and a telescopic spring 54. The guide post 53 is fixed to the bottom surface of the workbench 1 and penetrates through the cross beam 51, and a limit disk 531 is fixed to the bottom end of the guide post 53. The telescopic spring 54 is sleeved on the guide post 53 and is located between the workbench 1 and the cross beam 51. After adopting the above solution, the guide post 53 provided is used to guide the cross beam 51 to improve the stability of the cross beam 51. Cooperating with the provided telescopic spring 54, when the cross beam 51 moves, the telescopic spring 54 generates elastic deformation, and the telescopic spring 54 has a reverse elastic force, which further improves the smoothness of the cross beam 51.

[0042] Preferably, as Figure 1 shown, in this embodiment, the top surface of the lower heating die 2 is tangent to the outer wall of the fixed roller 42. Therefore, when the film bypasses the fixed roller 42 and moves onto the lower heating die 2, the film is in a horizontal state, which ensures the reliability of processing and improves the safety of the film, avoiding accidents such as scratches on the film.

[0043] Preferably, as Figure 1 and Figure 3As shown in the figure, in this embodiment, it further includes: a fixed block 21, a locking block 7, a fixing plate 6, and a horizontal cylinder 8.

Locking grooves 211 are provided at both ends of the fixed block 21. The locking block 7 is located in the locking groove 211, and the contact surface between the locking block 7 and the locking groove 211 is a matching inclined surface. The fixing plate 6 is fixed to the bottom surface of the workbench 1, the horizontal cylinder 8 is fixed on the fixing plate 6, and the piston rod of the horizontal cylinder 8 passes through the fixing plate 6 and is fixedly connected to the locking block 7. After adopting the above scheme, when installing the lower heating mold 2, the fixed block 21 is passed through the installation opening 11, and then the horizontal cylinder 8 is started. The piston rod of the horizontal cylinder 8 is used to push the locking block 7, so that the locking block 7 is inserted into the locking groove 211, and the fixed block 21 is clamped on both sides to realize the installation of the lower heating mold 2. Moreover, it is also convenient to disassemble, maintain or replace the lower heating mold 2. In addition, because the contact surface between the locking block 7 and the locking groove 211 is a matching inclined surface, the inclined surface force will generate a component force to pull down the fixed block 21, further improving the stability of the installation of the lower heating mold 2.

[0044] Preferably, by Figure 1 and Figure 3 As shown in the figure, in this embodiment, it further includes: guide rods 71. Two guide rods 71 are symmetrically fixed on the locking block 7, and the guide rods 71 pass through the fixing plate 6. After adopting the above scheme, the two guide rods 71 provided are used to guide the locking block 7, improving the stability of the locking block 7.

[0045] Preferably, by Figure 1 and Figure 3 As shown in the figure, in this embodiment, the outer wall of the fixed block 21 abuts against the inner wall of the installation opening 11, further ensuring the stability of the installation of the lower heating mold 2 and preventing the lower heating mold 2 from shaking.

[0046] Preferably, by Figure 1 and Figure 3 As shown in the figure, in this embodiment, the length of the locking block 7 is equal to the length of the locking groove 211. Therefore, when the locking block 7 is embedded in the locking groove 211, the end face of the locking block 7 abuts against the inner wall of the locking groove 211, further improving the stability.

[0048] The working principle and usage process of the present invention: For the hot pressing and forming mold of the present invention, during use, the film coil is fed by a dedicated feeding device and wound by a dedicated winding device. The upper heating mold 3 is driven by a hydraulic cylinder to move in the vertical direction for mold closing and mold opening;

[0049] During processing, the film is made to pass over the two fixed rollers 42 and under the movable roller 44. When the processing section of the film moves to the lower heating die 2, the hydraulic cylinder is activated to lower the upper heating die 3 for mold closing. Then, the adjusting mechanism 5 is activated to drive the movable side plate 43 downward, causing the movable roller 44 to move downward. The film is tightened by the cooperation of the movable roller 44 and the fixed rollers 42, putting the film in a tensioned state. The film is heated and compression molded by the lower heating die 2 and the upper heating die 3.

[0050] After molding, the hydraulic cylinder is activated to move the upper heating die 3 upward to separate it from the lower heating die 2. Then, the feeding device and the winding device are activated to transfer the film. The other positions of the film roll are subjected to hot pressing and molding processing in the same manner as described above.

[0051] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
