[0043] And when the sliding block 13 slides to the downward horizontal section on the guide groove 10, the lower surface of the suction head 3 will continuously adhere to the surface of the blue film 8 and transport the blue film 8;

[0044] In actual use, the guide track of the guide groove 10 can be adaptively improved to meet the actual use requirements, and is not limited to the parallelogram structure in the current scheme;

[0045] Embodiment 3:

[0046] Further based on the embodiment 2, further is:

[0047] The front side of the vertical support plate 9 is provided with a piston pipe 14 fixed on the top of the L-shaped air duct 2 and communicated with the L-shaped air duct 2, the left side of the vertical support plate 9 is slidably connected with a transmission sliding block 15 at the upper and lower limits, the inner wall of the transmission sliding block 15 is fixedly connected with a piston cylinder 16, the inner wall of the piston cylinder 16 is axially and slidably connected with a piston plate 17, the side of the piston plate 17 is fixedly connected with the end of the piston pipe 14, and the surface of the piston pipe 14 axially penetrates the piston cylinder 16 and is horizontally and limitingly slidably connected with the piston cylinder 16, the surface of the piston pipe 14 near one end of the piston plate 17 is penetrated and fixedly connected with a one-way valve one 18, the arc-shaped contour of the piston cylinder 16 near one end of the piston pipe 14 is penetrated and fixedly connected with a one-way valve two 19, and the suction head 3 is internally provided with an auxiliary pressing suction head.

[0048] The piston pipe 14 plays a transmission and air guiding role;

[0049] The piston pipe 14 with the piston plate 17 horizontally reciprocates in the piston cylinder 16, through the setting of the transmission sliding block 15, the piston cylinder 16 can reciprocate up and down on the vertical support plate 9, through the horizontal reciprocation of the piston plate 17 in the piston cylinder 16, a negative pressure environment can be created in the section of the piston cylinder 16 near the piston pipe 14, and through the negative pressure state, the suction operation of the blue film 8 is realized;

[0050] Specifically, when the piston pipe 14 with the piston plate 17 horizontally moves towards the vertical support plate 5, a negative pressure environment exists in the space of the right end of the piston cylinder 16, and conversely, when the piston pipe 14 with the piston plate 17 moves away from the vertical support plate 5, the air existing in the space of the right part of the piston cylinder 16 can be extruded, and the jetting air is helpful for the real-time adjustment of the positions of the feeding roller 6 and the collecting roller 7; the specific content of the adjustment is disclosed in the subsequent scheme;

[0051] Embodiment 4:

[0052] Further based on the embodiment 3, further is:

[0053] The auxiliary pressing suction head comprises a suction cavity 20 opened in the suction head 3, the inner top wall of the suction cavity 20 is fixedly connected with a compression spring 21, the bottom of the compression spring 21 is fixedly connected with a circular truncated cone sealing plug 22, the arc-shaped outer contour of the circular truncated cone sealing plug 22 is tightly fitted with the inner wall of the suction cavity 20, and the inner wall of the suction cavity 20 is provided with a gas guiding cavity 23 extending to the lower surface of the suction head 3.

[0054] Reference Figure 4When the right space of the piston cylinder 16 is in a negative pressure environment, the L-shaped air duct 2 and the piston tube 14 are in communication, so that the adsorption cavity 20 is also in a negative pressure environment. When the adsorption head 3 moves downward with the L-shaped air duct 2, the bottom of the circular truncated cone sealing plug 22 in the adsorption head 3 is in contact with the surface of the blue film 8 and is extruded, so that the circular truncated cone sealing plug 22 moves upward after overcoming the elastic force of the compression spring 21, so that there is a gap between the circular truncated cone sealing plug 22 and the inner wall of the adsorption cavity 20. The gap is in communication with the air guide cavity 23, so that the bottom of the air guide cavity 23 is in contact with the blue film 8 and quickly performs the adsorption operation. Thus, with the horizontal movement of the L-shaped air duct 2 and the adsorption head 3, the horizontal transfer and conveying of the blue film 8 are realized.

[0055] Embodiment 5:

[0056] Further, on the basis of embodiment 4:

[0057] The back of the vertical support plate 9 is fixedly connected with a support arm 24, the bottom of the piston cylinder 16 is fixedly connected with a rack one 25, the end of the support arm 24 away from the vertical support plate 9 is pivotally connected with a gear one 26, the teeth on the side of the gear one 26 away from the rack one 25 are drivingly engaged with a rack two 27, and the bottom of the rack two 27 is fixedly connected with a pressing plate 271 for pressing the blue film 8.

[0058] Reference Figure 5 :

[0059] With the lifting of the piston cylinder 16, the rack one 25 thereon also lifts, wherein the lifting of the piston cylinder 16 is synchronous with the lifting of the L-shaped air duct 2 and the adsorption head 3. Under the meshing transmission cooperation of the gear one 26, the rack two 27 moves in the opposite direction of the L-shaped air duct 2 and the adsorption head 3. When the adsorption head 3 adsorbs the blue film 8 at the lowest position and horizontally transfers and conveys the blue film 8, the rack two 27 is at the highest position, facilitating the pulling movement of the blue film 8.

[0060] Conversely, after the adsorption head 3 is separated from the adsorption contact with the blue film 8, before the next adsorption, the rack two 27 realizes the extrusion operation on the blue film 8 through the pressing plate 271 thereon, so that the blue film 8 can be stably conveyed on the horizontal support plate 1, avoiding the deviation of the direction and distance, and ensuring the stability during operation.

[0061] Embodiment 6:

[0062] Further, on the basis of embodiment 5:

[0063] The gear one 26 is provided with a cutting device cooperating with the cutting knife 4 to cut the blue film 8. The cutting device comprises a rotating shaft 28 rotating on the inner wall of the gear one 26. The rotating shaft 28 is rotatably connected to an upright plate 281 fixed on the edge of the horizontal support plate 1 at the end away from the support arm 24. An arc-shaped gear two 29 is fixedly connected to the arc-shaped contour of the rotating shaft 28 at the end away from the support arm 24. A torsion spring 30 is sleeved on the rotating shaft 28. The two ends of the torsion spring 30 are fixedly connected to the surfaces of the gear two 29 and the upright plate 281. The teeth of the gear two 29 are in transmission engagement with an L-shaped rack 31 sliding up and down on the upright plate 281. The surface of the L-shaped rack 31 close to the bottom is fixedly connected to the surface of the cutting knife 4. The piston plate 17 is fixedly connected to a pull rope 32 at the side away from the piston tube 14. The end of the pull rope 32 away from the piston plate 17 penetrates the end of the piston cylinder 16 and is wound and stored on the rotating shaft 28.

[0064] Reference Figure 5 And Figure 6 By moving the cutting knife 4 up and down, a fixed-distance cutting of the blue film 8 is realized.

[0065] By arranging the rotating shaft 28, the rotating shaft 28 can rotate relative to the gear one 26, drive the rotation of the gear two 29 on the rotating shaft 28, and further drive the lifting operation of the L-shaped rack 31 and the cutting knife 4, thereby realizing the corresponding cutting operation.

[0066] Specifically:

[0067] When the piston tube 14 moves towards the transmission sliding block 15 with the piston plate 17, the pull rope 32 is in a relaxed state. Under the action of the elastic force of the suction cavity 20, the gear two 29 rotates with the rotating shaft 28, the L-shaped rack 31 in engagement with the teeth of the gear two 29 and limited to slide up and down on the upright plate 281 is lowered, and the cutting knife 4 is lowered, thereby realizing the cutting operation of the cutting knife 4 on the blue film 8.

[0068] Conversely, when the piston tube 14 moves away from the vertical support plate 5 with the piston plate 17, the pull rope 32 is pulled again, so that the pull rope 32 wound on the rotating shaft 28 rotates with the pull rope 32 and the gear two 29 after overcoming the elastic force of the torsion spring 30, thereby realizing the upward operation of the L-shaped rack 31 and the cutting knife 4.

[0069] Embodiment 7:

[0070] On the basis of embodiment 6, further:

[0071] The inner wall of the discharging roller 6 is fixedly connected with a shaft one 33, one end of the shaft one 33 is vertically limitedly slid on the vertical support plate 5, the other end of the shaft one 33 is fixedly connected with a steering adjusting arm 37, the inner wall of the receiving roller 7 is fixedly connected with a shaft two 34, one end of the shaft two 34 is horizontally limitedly slid on the vertical support plate 5, the other end of the shaft two 34 is fixedly connected with an adjusting column 38, a through slot is formed in the adjusting column 38 away from one end of the shaft two 34, and the surface of the steering adjusting arm 37 is slidably connected with the through slot.

[0072] Reference Figure 6 And Figure 7 ;

[0073] Through the up-and-down limited sliding of the shaft one 33 on the vertical support plate 5, when the blue film 8 on the discharging roller 6 is pulled and transferred, there is a certain height difference between the top of the discharging roller 6 and the upper surface of the horizontal support plate 1, in order to achieve the best pulling separation effect, the discharging roller 6 needs to be timely moved upward on the vertical support plate 5 as a whole.

[0074] At the same time, with the continuous collection of the release paper by the receiving roller 7, the outer contour of the receiving roller 7 will continuously expand, so that the outer contour edge of the receiving roller 7 is no longer on the same vertical line as the outer contour edge of the discharging roller 6, and the shaft two 34 needs to be horizontally moved on the vertical support plate 5 to realize that the outer contour edge of the receiving roller 7 is on the same vertical line as the outer contour edge of the discharging roller 6, so as to realize the pulling of the blue film 8 and the efficient separation of the release film, and at the same time, the deformation of the blue film 8 is not easy to occur.

[0075] At the same time, in the present scheme, grooves are formed in the vertical support plate 5 for the limited sliding of the shaft one 33 and the shaft two 34, and the shaft one 33 and the shaft two 34 have friction damping in the corresponding grooves, so that they can continuously maintain a fixed position without changing under the condition of no external force intervention.

[0076] Through the upward movement of the shaft one 33, the synchronous movement of the steering adjusting arm 37 on the shaft one 33 is driven, since the shaft two 34 can only move horizontally in the vertical support plate 5, and due to the inclined arrangement of the steering adjusting arm 37, the upward movement of the steering adjusting arm 37 will cause the adjusting column 38 to move horizontally with the shaft two 34 and the receiving roller 7, thereby realizing the adjustment of the consistency of the outer contour.

[0077] The surface of the vertical support plate 5 is fixedly connected with a gas storage shell 35, the inner wall of the gas storage shell 35 is connected with a piston rod 36 which is limitedly slid upward and downward, the top of the piston rod 36 is a semicircular ring which is in contact with the surface of the shaft one 33, the top of the gas storage shell 35 is provided with a gas outlet hole, and the bottom of the one-way valve two 19 is in communication with the gas storage shell 35.

[0078] Reference Figure 7From the foregoing, the one-way valve 2 19 will spray air, in the present scheme, the one-way valve 2 19 can be communicated with the air storage shell 35 through the hose, the hose is the prior art known to those skilled in the art, therefore, not disclosed here;

[0079] The sprayed air will enter the air storage shell 35, and the high-pressure gas will lift the piston rod 36 upward, thereby achieving the lifting effect of the shaft 1 33. In order to prevent excessive lifting, the top of the vertical support plate 5 extends a baffle horizontally, and the lower surface of the baffle is on the same horizontal plane as the upper surface of the horizontal support plate 1.

[0080] At the same time, the air storage shell 35 is provided with an air outlet hole for discharging excess air, so that high-pressure air can be continuously injected into the air storage shell 35 in the future.

[0081] Although embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, replacements and changes can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
