As shown in fig. 12, a buffer spring is arranged in the output end of the third hydraulic cylinder 5, specifically, the buffer spring is arranged in the output end, so that the extrusion block 6 extrudes the copper foil plate 13 instantaneously, and the extrusion force on the copper foil plate 13 is too large, so that the side surface of the copper foil plate 13 is damaged by extrusion deformation.
The working principle is as follows: when the device is used, a copper foil plate 13 to be pressed is placed on the rotating conveying roller 11, the copper foil plate 13 is conveyed to the position below the supporting plate 12 to be pressed, the second hydraulic cylinder 2 arranged on the bottom surface of the supporting plate 12 drives the bearing plate 21 to move downwards, the bearing plate 21 drives the rolling cylinder 29 below to move synchronously, one end of the copper foil plate 13 is extruded, then a driving motor connected with the screw rod 26 is started to drive the screw rod 26 to be meshed with a threaded hole formed in the side surface of the sliding block 23, so that the sliding block 23 moves in the sliding groove 22, the linkage plate 24 drives the connecting block 25 to move synchronously, and the connecting block 25 drives the rolling cylinder 29 to move synchronously through the rotating shaft 28;
because the blue light membrane passes through the rolling of wind-up roll 16, the wind-up roll 16 that is located support plate 12 both sides sets up the blue light membrane in copper foil board 13 top, roll a 29 below, so roll a 29 with the blue light membrane and roll copper foil board 13 surface, because roll a 29 and be in by the heating state, consequently along with the removal of rolling a 29, the blue light membrane adhesion is on copper foil board 13 surface, and roll a 29 mobile mode and roll at copper foil board 13 one end and move to the other end, so the blue light membrane is gradually pressed and is covered on copper foil board 13 surface, the air between blue light membrane and the copper foil board 13 is driven gradually and is discharged, effectively avoided the remaining condition of air bubble to take place, the press mold effect has been improved, the press mold is accomplished the back, the cutter that accepts the setting of board 21 bottom cuts off the blue light membrane on copper foil board 13 border.
Wherein, in the plugboard 241 at connecting block 25 top inserted the braking groove 242, first extrusion spring 244 extrusion brake piece 243 made brake piece 243 and braking groove 242 inner wall have frictional force, set for the maximum extrusion force of a roll section of thick bamboo 29 to copper foil plate 13 of frictional force size, therefore when roll section of thick bamboo 29 continued the increase to copper foil plate 13 extrusion force, brake piece 243 can remove for braking groove 242, consequently, avoided roll section of thick bamboo 29 too big to copper foil plate 13's extrusion force, influence the stability of press mold, and prevented that copper foil plate 13 from being crushed.
When a rolling section of thick bamboo 29 is pressed and is covered blue light membrane to copper foil plate 13 surface, the blue light membrane is extrudeed, drive wind-up roll 16 and rotate, because when normal wind-up roll 16 was to the blue light membrane rolling, drive transmission shaft 3 through 3 one end motors of transmission shaft and rotate, later drive friction pulley 31 and rotate, drive connecting axle 15 through the frictional force effect and rotate, connecting axle 15 drives wind-up roll 16 and rotates, so wind-up roll 16 is not in the card dead state, when the blue light membrane was extruded and is driven wind-up roll 16 and rotate, can provide frictional force to connecting axle 15 through the extrusion of second extrusion spring 33 with connecting axle 15 side extruded friction disc 34, make wind-up roll 16 rotate by the restriction, the not hard up phenomenon of blue light membrane has effectively been avoided, the blue light membrane that is in the tight state has improved the stability of press mold.
When the blue light membrane is extruded by the rolling cylinder 29, the blue light membrane can be supported by the supporting cylinder 42, the supporting cylinder 42 is uniformly arranged on the supporting shaft 41, the supporting shaft 41 is arranged on two sides of the bearing plate 21 through the fourth mounting plate 4, the supporting cylinder 42 supports the blue light membrane, the two sides of the blue light membrane bearing plate 21 are prevented from being supported at the tip, and the blue light membrane is damaged.
When rolling a section of thick bamboo 29 press mold, need keep certain temperature, heat rolling a section of thick bamboo 29 through inserting heating rod 292 at spliced eye 291 for rolling a section of thick bamboo 29 and being heated evenly, guarantee the press mold quality.
When the connecting block 25 drives the rolling cylinder 29 to move, the fastening frame 251 at the top of the connecting block 25 is fastened on the upper side and the lower side of the bearing plate 21, so that when the connecting block 25 moves, the fastening frame 251 can limit the moving direction of the connecting block 25, the shaking of the connecting block 25 caused by the vibration of the device is avoided, and the rolling cylinder 29 keeps stable during film pressing, and the quality of the film pressing is further ensured.
When the copper foil board 13 enters into and supports 12 below, first pneumatic cylinder 17 can prop up frame 18, lead to propping up 18 top surfaces and prop up copper foil board 13, when the film pressing to copper foil board 13, third pneumatic cylinder 5 starts, the output drives the dummy block 6 and extrudes copper foil board 13 side, the removal of copper foil board 13 has been restricted, make copper foil board 13 remain stable when the film pressing, the removal appears in the unevenness of copper foil board 13 atress when avoiding rolling a section of thick bamboo 29 film pressing, the unusual risk of film pressing has been reduced.
When extruding the copper foil plate 13 through the extrusion block 6, when the difference appears in the thickness of the copper foil plate 13, the extrusion plate 63 arranged inside the rectangular notch 61 can replace the extrusion block 6 to extrude the restriction copper foil plate 13 under the effect of the supporting spring 62, so that the structure of the restriction copper foil plate 13 has adjustability and is suitable for the copper foil plates 13 with various sizes and thicknesses.
Through being provided with buffer spring in the output for the too big copper foil board 13 extrusion force of extrusion piece 6 extrusion in the twinkling of an eye causes the copper foil board 13 side to be extruded deformation and damages.
The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above-mentioned embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and embellishments within the scope of the invention may occur to those skilled in the art without departing from the principle of the invention, and are considered to be within the scope of the invention.
