Description

Technical Field

[0001] This utility model relates to the technical field of stripping equipment, specifically an automatic stripping device for producing ion exchange membranes using the casting method. Background Technology

[0002] Currently, in the process of producing functional films by casting, PET film is often used as a temporary carrier to support the casting and curing of the film solution.

[0003] Therefore, before the functional membrane (ion exchange membrane) is wound up after subsequent production, it needs to be peeled off from the PET membrane. If the PET carrier membrane is not peeled off, the functional membrane will fail. As a result, some existing peeling operations cause wrinkles at the edges of the functional membrane and the EPT carrier, resulting in damage to the functional membrane. Utility Model Content

[0004] The purpose of this invention is to provide an automatic peeling device for producing ion exchange membranes by casting, so as to overcome the shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a frame, an unwinding mechanism mounted on the frame, and two winding mechanisms mounted on the frame. It also includes a peeling mechanism for separating the carrier membrane and the ion exchange membrane. The peeling mechanism includes: a first slide rail mounted on the frame; a sliding table slidably connected to the first slide rail via a slide bar, with a first adsorption unit for adsorbing the ion exchange membrane on the sliding part; and a peeling roller rotatably and slidably connected to the frame, with a second adsorption unit for adsorbing the carrier membrane on its peripheral side. During the sliding of the sliding table relative to the frame, a transmission mechanism drives the peeling roller to rotate relative to the frame, thereby separating the ion exchange membrane adsorbed by the first adsorption unit from the carrier membrane adsorbed by the second adsorption unit.

[0006] Preferably, the first adsorption unit includes a first cavity formed in the peeling roller, and the peripheral side of the peeling roller has a plurality of first air ports communicating with the first cavity; the second adsorption unit includes a second cavity formed in the sliding table, and the adsorption surface of the sliding table has a plurality of second air ports communicating with the second cavity; the first cavity and the second cavity are respectively connected to an external vacuum pump through an air extraction pipe.

[0007] Preferably, the transmission mechanism includes a first gear fixedly connected to the stripping roller on the same axis, and a first rack that meshes with the first gear is provided on the sliding table.

[0008] Preferably, a first guide roller group is provided between the peeling roller and the winding mechanism for winding the carrier membrane, and a second guide roller group is provided between the sliding table and the winding mechanism for winding the ion exchange membrane.

[0009] Preferably, a second slide rail is provided on the frame, a slider is slidably connected in the second slide rail, the slider is rotatably connected to the peeling roller on the same axis, and a limiting mechanism is provided between one end of the second slide rail and the peeling roller. A first mating roller that abuts against the peeling roller is rotatably connected on the frame.

[0010] Preferably, the limiting mechanism includes an eccentric column fixedly connected to the peeling roller via a connecting rod, and a third slide rail is provided on the frame for the eccentric column to slide on. The third slide rail includes a first arc groove and a lower straight groove connected in sequence.

[0012] Preferably, a drive cylinder for driving the sliding table to slide horizontally along the first slide rail is fixedly connected to the frame, and the telescopic end of the drive cylinder is fixedly connected to the sliding table.

[0013] Compared with existing technologies, this utility model provides an automatic peeling device for producing ion-exchange membranes using a casting method. During operation, the release section of the ion-exchange membrane with a carrier membrane is first laid flat on a sliding table. A first adsorption unit adsorbs the ion-exchange membrane with the carrier membrane. Then, the sliding table is driven to slide along a first slide rail until the lowest point of the peeling roller contacts the carrier membrane. At this point, a second adsorption unit begins to adsorb the carrier membrane. Simultaneously, the sliding table continues to slide along the first slide rail, and a transmission mechanism rotates the peeling roller, thus separating the carrier membrane from the ion-exchange membrane. During this process, the first adsorption unit maintains the ion-exchange membrane in a flat state, while the carrier membrane is wound and flatly adsorbed onto the surface of the peeling roller. This peeling process avoids wrinkles in the carrier membrane and ion-exchange membrane, effectively preventing damage to both. Attached Figure Description

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-7This utility model provides an automatic peeling device for producing ion-exchange membranes using a casting method. It includes a frame 1, an unwinding mechanism 2 mounted on the frame 1, and two winding mechanisms 3 mounted on the frame 1 for winding the film. It also includes a peeling mechanism 4 for separating the carrier membrane from the ion-exchange membrane. The peeling mechanism 4 includes a first slide rail 41, a sliding table 42, and a peeling roller 44. The first slide rail 41 is located on the frame 1. The sliding table 42 is slidably connected to the first slide rail 41 via a slide bar, and a first adsorption unit 43 for adsorbing the ion-exchange membrane is provided on the sliding part. The peeling roller 44 is rotatably and slidably connected to the frame 1, and a second adsorption unit 45 for adsorbing the carrier membrane is provided on the peripheral side of the peeling roller 44. During the sliding of the sliding table 42 relative to the frame 1, the peeling roller 44 is driven to rotate relative to the frame 1 via a transmission mechanism 5, causing the ion-exchange membrane adsorbed by the first adsorption unit 43 and the carrier membrane adsorbed by the second adsorption unit 45 to be peeled and separated. It should be noted that the unwinding mechanism 2 is prior art, which includes an unwinding roller rotatably connected to the frame 1, and an ion exchange membrane with a carrier membrane is wound on the unwinding roller; it should also be noted that the two winding mechanisms 3 are also prior art, wherein each unwinding mechanism 2 includes a winding roller rotatably connected to the frame 1, one winding roller is used to wind up the carrier membrane, and the other winding roller is used to wind up the ion exchange membrane.

[0026] Specifically, during operation, the release section of the ion exchange membrane with the carrier membrane is first laid flat on the sliding table 42, and the first adsorption unit 43 adsorbs the ion exchange membrane with the carrier membrane. Then, the sliding table 42 is driven to slide along the first slide rail 41 until the lowest end of the peeling roller 44 contacts the carrier membrane. At this point, the second adsorption unit 45 starts to work to adsorb the carrier membrane. At the same time, the sliding table 42 continues to slide along the first slide rail 41 and cooperates with the transmission mechanism 5 to make the peeling roller 44 rotate. This makes the carrier membrane and the ion exchange membrane peel off and separate. During this process, the first adsorption unit 43 maintains the ion exchange membrane in a flat state, while the carrier membrane is rolled up and flatly adsorbed on the surface of the peeling roller 44. This peeling process avoids wrinkles in the carrier membrane and the ion exchange membrane, effectively avoiding the problem of damage to the carrier membrane and the ion exchange membrane.

[0027] The first adsorption unit 43 includes a first cavity (not shown in the figure) formed within a peeling roller 44, and several first air ports communicating with the first cavity are formed on the peripheral side of the peeling roller 44. The second adsorption unit 45 includes a second cavity (not shown in the figure) formed within a sliding table 42, and several second air ports communicating with the second cavity are formed on the adsorption surface of the sliding table 42. The first cavity and the second cavity are respectively connected to an external vacuum pump through suction pipes. It should be noted that each suction pipe to the first cavity and the suction pipe to the second cavity is equipped with a separate control valve (not shown in the figure), and a prior art controller is also provided. The external vacuum pump and the two control valves are electrically connected to the controller, and the external vacuum pump and the two control valves work in coordination under the control of the controller.

[0028] Specifically, when the external vacuum pump is turned on, the first adsorption unit 43, in cooperation with the controller and the corresponding control valve, begins to draw air from the first cavity, and at this time, each of the first air ports can adsorb the ion membrane; similarly, the second adsorption unit 45, in cooperation with the controller and the corresponding control valve, begins to draw air from the second cavity, and at this time, each of the second air ports can adsorb the carrier membrane.

[0029] The transmission mechanism 5 includes a first gear 51 coaxially and fixedly connected to the stripping roller 44, and a first rack 52 meshing with the first gear 51 on the sliding table 42. It should be noted that the first rack 52 and the first gear 51 are always in a meshing state.

[0030] Specifically, during the sliding process of the first slide rail 41 of the sliding table 42, the first rack 52 slides along the sliding table 42 and drives the first gear 51 to rotate, thereby driving the peeling roller 44 to rotate. As a result, the peeling roller 44, in conjunction with the second adsorption unit 45 in the working state, can adsorb the carrier membrane, thereby peeling the carrier membrane from the ion membrane.

[0031] Specifically, a first guide roller group 6 is provided between the peeling roller 44 and the winding mechanism 3 for winding the carrier membrane, and a second guide roller group 7 is provided between the sliding table 42 and the winding mechanism 3 for winding the ion exchange membrane. Specifically, as shown... Figure 1 As shown, the first guide roller group 6 preferably has two guide rollers rotatably connected, and the outer surfaces of the two guide rollers have a clean cloth tape with a clean carrier film; similarly, the first guide roller group 6 preferably has four guide rollers rotatably connected, and the outer surfaces of the last two guide rollers closest to the corresponding winding mechanism 3 also have a clean cloth tape.

[0032] In a preferred embodiment of this solution, a second slide rail 8 is provided on the frame 1, and a slider 9 is slidably connected within the second slide rail 8. The slider 9 is coaxially and rotatably connected to the peeling roller 44, and a limiting mechanism 10 is provided between one end of the second slide rail 8 and the peeling roller 44. A first mating roller 11 that abuts against the peeling roller 44 is rotatably connected to the frame 1. The limiting mechanism 10 includes an eccentric column 101 fixedly connected to the peeling roller 44 via a connecting rod. A third slide rail 102 is provided on the frame 1 for the eccentric column 101 to slide. The third slide rail 102 includes a first arc groove 1021 and a straight groove connected in sequence. A first push rod 12 that pushes the slider 9 to slide within the second slide rail 8 is fixedly connected to the sliding table 42.

[0033] It should be noted that when the peeling roller 44 abuts against the first mating roller 11, the surface of the peeling roller 44 and the first mating roller 11 can abut and clamp the carrier membrane, allowing the operator to shut down the second adsorption unit 45. This facilitates the operator in pulling the carrier membrane to the first guide roller group 6, preventing the operator from having difficulty removing the carrier membrane and pulling it to the first guide group when the second adsorption unit 45 is working, and preventing the carrier membrane from naturally sagging when the operator shuts down the second adsorption unit 45. This process reduces the difficulty of pulling the carrier membrane and avoids damage to the carrier membrane for reuse. Furthermore, it should be noted that an elastic soft rubber pad is fixedly connected to the outer surface of the peeling roller 44, facilitating the adsorption of the carrier membrane by the second adsorption unit 45. At the same time, it provides a certain amount of pressure between the peeling roller 44 and the surface of the sliding table 42. Thus, when the first adsorption unit 43 stops working, the ion membrane can still be laid flat on the sliding table 42, making it easy for the operator to pull the ion membrane to the second guide roller group 7.

[0034] The frame 1 is fixedly connected to a drive cylinder 15 for driving the sliding table 42 to slide horizontally along the first slide rail 41. The telescopic end of the drive cylinder 15 is fixedly connected to the sliding table 42.

[0035] Specifically, the process of the sliding stage 42 receiving the push from the drive cylinder 15 and sliding within the first slide rail 41 includes the following three strokes: In the first stroke, the sliding stage 42 slides along the first slide rail 41 until the carrier film contacts the lowest point of the peeling roller 44, and drives the second adsorption unit 45 to work; In the second stroke, the sliding stage 42 continues to slide and drives the first rack 52 and the first gear 51 to engage in transmission to make the peeling roller 44 rotate, and with the cooperation of the second adsorption unit 45, the carrier film can be peeled off from the ion membrane; In the third stroke, the sliding stage 42 continues to slide along the first slide rail 41, at which time the first gear 51 disengages from the first rack 52, until the first push rod 12 pushes the slider 9 to drive the slider 9 to slide along the second slide rail 8, until the peeling roller 44 abuts against the first mating roller 11.

[0036] In the second stroke, the eccentric block is located in the first arc groove 1021 and at this time, the eccentric block is located at the closed end of the first arc groove 1021. This allows the first rack 52 and the first gear 51 to mesh and drive the peeling roller 44 to rotate. The eccentric block will rotate along the first arc groove 1021 to the junction between the first arc groove 1021 and the lower straight groove 1022. Then, in the third stroke, the first push rod 12 will push the slider 9 so that the slider 9 slides linearly from one end of the second slide rail 8 to the other end of the sliding table 42, thereby making the peeling roller 44 slide synchronously with the sliding table 42 until the peeling roller 44 abuts against the first mating roller 11. When the two winding mechanisms 3 finish winding, the drive cylinder 15 will drive the sliding table 42 to return along the first slide rail 41. Since the first gear 51 and the first rack 52 are in a meshing state, the first gear 51 and the first rack 52 will not drive the first gear 51 to rotate because the eccentric block is located in the lower straight groove 1022. As a result, when the first rack 52 slides with the sliding table 42, it can drive the first gear 51 to slide synchronously, that is, drive the stripping roller 44 to slide in a straight line until the eccentric block is located at the junction of the lower straight groove 1022 and the first arc groove 1021. At this time, the first rack 52 will mesh with the first gear 51 to make the stripping roller 44 rotate.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
