[0027] See also Figures 1 to 3 Now, an automatic glue removal device for an empty roll provided by the utility model is described. An automatic glue removal device for an empty roll includes a tape 12 clamping assembly, an action switching unit 4 and a station switching unit 5.

[0028] The tape 12 clamping assembly includes a first clamping plate 11 and a second clamping plate 8 which are arranged on one side of the empty reel 1 with the remaining tape 12, the first clamping plate 11 being located above the second clamping plate 8 and the two being hinged in the middle; the action switching unit 4 is connected to the end of the second clamping plate 8 which is away from the empty reel 1, and the action switching unit 4 drives the end of the second clamping plate 8 away from the empty reel 1 to rise and fall, so that the first clamping plate 11 and the second clamping plate 8 are close to the end of the empty reel 1 to clamp the end of the tape 12 or loosen the end of the tape 12; the workstation switching unit 5 is located on the side of the tape 12 clamping assembly away from the empty reel 1, and the workstation switching unit 5 is connected to the first clamping plate 11, and is used to drive the tape 12 clamping assembly to approach the empty reel 1 or away from the empty reel 1.

[0029] The utility model provides an automatic glue removal device for an empty roll. Compared with the prior art, the first clamping plate 11 and the second clamping plate 8 are located on one side of the empty roll 1, and the first clamping plate 11 is located above the second clamping plate 8 and is hinged in the middle. The action switching unit 4 is connected to the end of the second clamping plate 8 away from the empty roll 1, and the station switching unit 5 is connected to the first clamping plate 11. When using the automatic glue removal device for an empty roll provided by the utility model, the station switching unit 5 drives the adhesive tape 12 clamping assembly to approach the empty roll 1 and reach the working area. The action switching unit 4 drives the end of the second clamping plate 8 away from the empty roll 1 to descend, and the end of the second clamping plate 8 close to the empty roll 1 rises to cooperate with the first clamping plate 11 to clamp the end of the adhesive tape 12 on the empty roll 1. As the empty roll 1 rotates, the adhesive tape 12 is removed from the empty roll 1. After the adhesive tape 12 is removed, the action switching unit 4 drives the end of the second clamping plate 8 away from the empty roll 1 to rise, and the end of the second clamping plate 8 close to the empty roll 1 to drop to loosen the end of the adhesive tape 12 on the empty roll 1, and the station switching unit 5 drives the adhesive tape 12 clamping assembly away from the empty roll 1 to reach the non-working area. The utility model provides an automatic adhesive removal device for an empty roll, which can quickly remove the adhesive tape 12 substrate, realize the automatic removal of the adhesive area of ​​the empty roll 1, and greatly improve the production efficiency.

[0030] The automatic glue removal equipment for empty rolls also includes a transverse guide mechanism, which is located above the first clamping plate 11 and connected to the first clamping plate 11. The workstation switching unit 5 drives the tape 12 clamping assembly to approach the empty roll 1 or move away from the empty roll 1 with the help of the transverse guide mechanism.

[0031] Specifically, the transverse guide mechanism includes a guide rail 2 and a slider 3. The guide rail 2 is horizontally arranged above the slider 3. The first clamp 11 is installed on the slider 3. The workstation switching unit 5 is located on the side of the guide rail 2 away from the empty roll 1. The action switching unit 4 is installed on the slider 3. The slider 3 is slidably arranged along the guide rail 2, and can guide the first clamp 11 and the second clamp 8 to move synchronously laterally to reach the working area or the non-working area, ensuring that the first clamp 11 and the second clamp 8 are more stable when switching between the working area and the non-working area.

[0032] The upper end surface of the second clamping plate 8 close to the empty roll 1 is provided with a rubber pad 10, and the rubber pad 10 is bonded to the upper end surface of the second clamping plate 8 close to the empty roll 1. The rubber pad 10 cooperates with the first clamping plate 11 to clamp the tape 12, and the presence of the rubber tape 12 can increase the clamping force of the tape 12 to prevent the tape 12 from falling off.

[0033] Preferably, the upper end surface of the first clamping plate 11 near the empty roll 1 has an inclined surface, and the horizontal angle of the inclined surface is 30°. The inclined surface forms a sharp angle structure at the end of the first clamping plate 11 near the empty roll 1, and the end of the sharp angle abuts against the outer wall of the empty roll 1, and the glue mark can be removed as the empty roll 1 rotates.

[0034] Preferably, a blowing nozzle 9 is provided on the lower end surface of the first clamping plate 11, and the blowing direction of the blowing nozzle 9 is toward one side of the empty roll 1. When the end of the second clamping plate 8 moves downward to release the adhesive tape 12, the adhesive tape 12 may stick to the first clamping plate 11 or the second clamping plate 8, and the blowing nozzle 9 provides high-pressure gas to blow the adhesive tape 12 off the first clamping plate 11 or the second clamping plate 8.

[0035] Optionally, the station switching unit 5 is any one of a cylinder, a hydraulic cylinder, a linear motor or a ball screw assembly. The action switching unit 4 is any one of a cylinder, a hydraulic cylinder, a linear motor or a ball screw assembly.

[0036] The automatic glue removal device for empty rolls also includes a fixing seat 6, the upper end of which is connected to the driving end of the station switching unit 5, and the lower end of which is connected to a color mark sensor 7, with the sensing end of the color mark sensor 7 facing the empty roll 1. The color mark sensor 7 detects the position of the end of the adhesive tape 12 on the empty roll 1. When the color mark sensor 7 detects the end of the adhesive tape 12, the empty roll 1 stops rotating, the station switching unit 5 drives the adhesive tape 12 clamping assembly to approach the empty roll 1, and the action switching unit 4 drives the second clamping plate 8 to cooperate with the first clamping plate 11 to clamp the end of the adhesive tape 12, and then the empty roll 1 rotates again, thereby continuously pulling the adhesive tape 12 off the empty roll 1.

[0037] In addition, the device can be applied to the following tape 12 schemes: 1. Customized tape 12 is used. The customized tape 12 uses a grid substrate for easy removal. The substrate includes a glue area and a non-glue area. The non-glue area is used to extend between the first clamping plate 11 and the second clamping plate 8 as the clamping end of the tape 12; 2. Ordinary grid substrate double-sided tape is used, but when the tail is removed, a 5-15mm tail head is left for clamping and removal. Specific parameters such as the length of the first clamping plate 11 and the second clamping plate 8 and the number of related power mechanisms can be determined according to the length of the empty reel 1. When the empty reel 1 is glued, a semi-coated substrate customized tape 12 is used to cooperate with the glue removal equipment to complete the glue removal action, thereby simplifying the equipment and improving the success rate of glue removal. The glue removal method of the empty reel 1 is in the circumferential direction of the reel, which can avoid the problem of substrate breakage caused by too long axial glue removal stroke, thereby improving the success rate of glue removal.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
