[0032] The embodiment of the present application provides an elastic sand film peeling device, as Figure 1 shown. The elastic sand film peeling device may include a support base 1, a conveying roller 11, a release paper roller 12, a take-up reel 14, a flattening roller 13, a driving roller 15, a differential roller 16, a servo motor 2, a driving wheel 121, a variable diameter component 3, and a synchronous belt 21.

[0033] Among them, the support base 1 is fixedly installed with two first support arms 101, two second support arms 102, and several third support arms 103 that are symmetrically arranged respectively; several conveying rollers 11 are provided and are respectively rotatably installed on several third support arms 103; the release paper roller 12 is rotatably arranged at one end of the two second support arms 102 close to the support base 1; the take-up reel 14 is rotatably installed at one end of the two first support arms 101 away from the support base 1.

[0034] The flattening roller 13 is arranged at one end of the two second support arms 102 far from the support base 1 and is located on the front side of the winding shaft 14; the driving roller 15 is movably arranged at one end of the two first support arms 101 far from the support base 1 and is in contact with one side of the winding shaft 14; the differential roller 16 is movably arranged at one end of the two first support arms 101 far from the support base 1 and is in contact with the other side of the winding shaft 14; the flattening roller 13 is arranged on the front side of the winding shaft 14 for flattening the material before winding. The driving roller 15 and the differential roller 16 are in contact with the winding shaft 14 and drive the winding shaft 14 to rotate through friction when rotating to realize winding. When there is a speed difference between the two, the tightness of winding can be adjusted.

[0035] The servo motor 2 is fixedly installed at one end of the first support arm 101 close to the support base 1; there are two driving wheels 121. One passes through the second support arm 102 and is connected to the release paper roller 12, and the other passes through the first support arm 101 and is connected to the driving roller 15; the variable diameter assembly 3 is fixedly installed at one end of the differential roller 16; the synchronous belt 21 is sleeved on the output ends of the driving wheel 121, the variable diameter assembly 3 and the servo motor 2; the servo motor 2 drives the synchronous belt 21 through rotation, and then drives the driving wheel 121 and the variable diameter assembly 3 to drive the rollers connected thereto to rotate.

[0036] As Figure 8 shown, the release paper 6 passes through the conveying roller 11 and is connected to the release paper roller 12; the elastic sand film 7 passes through the conveying roller 11 and is connected to the winding shaft 14.

[0037] Specifically, when the device works, the servo motor 2 starts, and its output end rotates clockwise, driving the driving wheel 121 and the variable diameter assembly 3 to rotate clockwise, driving the release paper roller 12, the driving roller 15 and the differential roller 16 to rotate. The driving roller 15 and the differential roller 16 are in contact with the winding shaft 14 and drive the winding shaft 14 to wind through friction. At the same time, the setting of the flattening roller 13 can flatten the material conveyed by the conveying roller 11, avoid wrinkles generated by the material during winding due to elasticity, ensure the winding effect when separating the release paper 6, improve the working efficiency of the equipment, and save labor costs.

[0038] Furthermore, four mounting shafts 17 are symmetrically arranged on the first support arm 101. The movable arms 18 are sleeved on the mounting shafts 17. The driving roller 15 is rotatably installed between two of the movable arms 18, and the differential roller 16 is rotatably installed between the other two movable arms 18. A spring 19 is fixedly installed between the two movable arms 18 on one side.

[0039] Specifically, the movable arm 18 can rotate along the mounting shaft 17, and the driving roller 15 and the differential roller 16 can always be in close contact with the winding shaft 14 and the material thereon through the spring 19, and can automatically adapt to different radius sizes when the radius changes after winding, so as to drive the winding shaft 14 to wind.

[0040] In some embodiments, the flattening roller 13 is a strip-shaped flattening roller.

[0041] Please continue to refer to Figure 3 and Figure 4 In the exemplary embodiment, the variable diameter assembly 3 may include a fixed shaft 31, a first guiding groove 311, a moving arm 32, a turntable 33, a second guiding groove 331, a guiding block 321, and an electric push rod 34. Among them, the fixed shaft 31 passes through the movable arm 18 and is fixedly connected to the differential roller 16. A plurality of first guiding grooves 311 are provided on the fixed shaft 31 and are distributed in an annular array. The moving arm 32 is slidably arranged in the first guiding groove 311. The turntable 33 is rotatably installed on the fixed shaft 31. The second guiding groove 331 is opened on the turntable 33 and corresponds to the position of the moving arm 32. The guiding block 321 is fixedly installed on the moving arm 32 and is adapted to the second guiding groove 331. The electric push rod 34 is rotatably installed on the fixed shaft 31, and the movable end of the electric push rod 34 is rotatably connected to the turntable 33.

[0042] Specifically, when it is necessary to adjust the outer diameter of the variable diameter assembly 3, the electric push rod 34 is started. The electric push rod 34 pushes the turntable 33 to rotate relative to the fixed shaft 31. When the turntable 33 rotates, the second guiding groove 331 thereon will cause the guiding block 321 to drive the moving arm 32 fixedly connected thereto to slide in the radial direction along the first guiding groove 311. When the moving arms 32 distributed in an annular array move synchronously in the radial direction, their outer diameter profiles will be changed, thereby adjusting the outer diameter of the synchronous belt 21 connected thereto, and further changing the angular velocity difference between the differential roller 16 and the driving roller 15, so as to adjust the tightness of the winding of the winding shaft 14.

[0043] Please continue to refer to Figure 5 、 Figure 6 and Figure 7 In the exemplary embodiment, a cleaning assembly 5 is provided on the first support arm 101, and a driving assembly 4 connected to the cleaning assembly 5 is provided on the first support arm 101.

[0044] Specifically, the servo motor 2 outputs power to the cleaning assembly 5 through the driving assembly 4, and then the driving roller 15 and the differential roller 16 are cleaned through the cleaning assembly 5.

[0045] Further, the driving assembly 4 may include a toothed ring 41, a driving disk 42, a pawl 43, a spring piece 44, and a transmission belt 22. The toothed ring 41 is rotatably installed on the first support arm 101. The driving disk 42 is located in the toothed ring 41 and is connected to the cleaning assembly 5. The pawl 43 is rotatably installed on the driving disk 42 and is adapted to the toothed ring 41. The spring piece 44 is fixedly installed on the driving disk 42 and corresponds to the position of the pawl 43. The transmission belt 22 is sleeved on the driving end of the toothed ring 41 and the servo motor 2.

[0046] Specifically, the output end of the servo motor 2 is connected to the toothed ring 41 through the transmission belt 22. When the winding is separated, the output end of the servo motor 2 rotates clockwise. At this time, the toothed ring 41 rotates clockwise under the action of the transmission belt 22. The teeth of the toothed ring 41 press the pawl 43, and then press down the spring piece 44. At this time, the driving disk 42 is in a static state, and the cleaning assembly 5 does not work. When the material is removed after the winding is completed, the servo motor 2 is driven to rotate in the reverse direction, driving the toothed ring 41 to rotate counterclockwise. At this time, the teeth are engaged with the pawl 43, and the toothed ring 41 drives the driving disk 42 to rotate counterclockwise, thereby driving the cleaning assembly 5 to perform cleaning.

[0047] In some embodiments, the cleaning assembly 5 may include a reciprocating lead screw 51, a slider 53, a guide plate 52, and a water spray port 532. The reciprocating lead screw 51 is rotatably installed on the first support arm 101 and is fixedly connected to the driving disk 42. The slider 53 is sleeved on the reciprocating lead screw 51. There are two guide plates 52, which are fixedly installed on the first support arm 101 and are adapted to the slider 53. The water spray port 532 is arranged on the slider 53.

[0048] Specifically, the driving disk 42 drives the reciprocating lead screw 51 to rotate counterclockwise. Under the action of the guide plate 52, the slider 53 reciprocates along the reciprocating lead screw 51. There are two groups of water spray ports 532 on the slider 53 facing the driving roller 15 and the differential roller 16. The slider 53 is connected to a common water cleaning device, and when reciprocating, it sprays and cleans the roller through the water spray port 532.

[0049] In some embodiments, two sets of relief grooves 531 are formed at the other end of the slider 53. A fixed arm 55 is slidably arranged in the relief grooves 531. A compression spring 54 is fixedly arranged between the fixed arm 55 and the relief grooves 531. A limiting edge 551 adapted to the relief grooves 531 is arranged at the bottom of the fixed arm 55. A cleaning block 56 is arranged at the other end of the fixed arm 55.

[0050] Specifically, after the slider 53 is flipped, the fixed arm 55 can be ejected by the compression spring 54 to contact the roller on the other side. A cleaning block 56 for cleaning the roller is fixed at the other end of the fixed arm 55. After the cleaning block 56 contacts the roller, the driving roller 15 and the differential roller 16 rotate under the drive of the servo motor 2, and wipe and clean when rotating in contact with the cleaning block 56.

[0051] In some embodiments, a L-shaped relief plate 521 is fixedly installed at one end of the guide plate 52. The two guide plates 52 are symmetrically arranged with respect to the reciprocating lead screw 51. One end of the slider 53 is a semi-cylindrical shape concentric with the reciprocating lead screw 51, and the other end is a rectangular shape.

[0052] Specifically, when the slider 53 moves to the other end along the reciprocating screw 51, the yield plate 521 no longer guides the slider 53, and the slider 53 will rotate under the friction of the reciprocating screw 51, thereby flipping over. Because one side of the slider 53 is semi-cylindrical, it will not encounter any obstacles when rotating. After rotating 180°, the rectangular part will contact the guide plate 52 on the other side that is centrally symmetrically arranged, and stop rotating under the action of the guide plate 52, and move back along the reciprocating screw 51 under the guidance. When it moves to the end, it flips over again under the action of the yield plate 521 on the other side, thereby repeating the steps of washing and wiping.

[0053] In some embodiments, the cleaning block 56 may be detachable and may be a cleaning sponge.

[0054] It is understandable that the cleaning sponge can be disassembled and replaced, and the cleaning sponge, pushed by the compression spring 54, can better fit with the driving roller 15 and the differential roller 16 to achieve a better cleaning effect.

[0055] The elastic sand film stripping device proposed in the embodiment of the present application rewinds the separated release paper 6 through the release paper roller 12, and recovers the separated elastic sand film 7 through the rewinding shaft 14; controls the speed difference between the driving roller 15 and the differential roller 16 through the variable diameter component 3, thereby adjusting the tightness of the rewinding of the elastic sand film 7; flattens the elastic sand film 7 through the flattening roller 13 to avoid wrinkles during rewinding due to the elastic characteristics; realizes one-way linkage work through the driving component 4; and cleans the driving roller 15 and the differential roller 16 of the rewinding elastic sand film 7 after rewinding through the cleaning component 5 to remove sand and other impurities attached to the rollers, thereby ensuring the normal use of the driving roller 15 and the differential roller 16, thereby ensuring the rewinding effect when separating the release paper 6, and being able to automatically clean the separation device, thereby improving the working efficiency of the equipment and saving labor costs.

[0056] The above are only preferred embodiments of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
