Description

Technical Field

[0001] The utility model relates to the field of tape production, in particular to a slitting device for a tape production line. Background Technique

[0002] In the production process of tapes, usually a wide-width tape original roll is first produced, and then according to production requirements, the wide-width tape original roll is slit into tape rolls of corresponding widths. However, during the slitting and winding process, the phenomenon of deviation is likely to occur, resulting in uneven edges at both ends of the tape roll and affecting the production quality.

[0003] After searching the patent document with the publication number of CN213387025U, the device in this patent document corrects the deviation of the tape by arranging support columns at the winding position and using the inclined surfaces of the support columns to make the deviated tape fall back onto the surface of the support columns.

[0004] The device in this patent document only relies on the inclined surfaces of the support columns to correct the deviation of the deviated tape, which may make the two edges of the tape roll uneven. Moreover, the tape has a certain adhesiveness and is likely to stick to the inclined surfaces of the support columns, thus possibly affecting the deviation correction effect. At the same time, this device does not consider the problem of air bubbles easily generated during tape winding. Content of the Utility Model

[0027] The present utility model will be further described below with reference to the drawings:

[0028] As Figures 1 - 7As shown in the figure, a slitting device for a tape production line includes a slitting mechanism 2, and also includes a bubble removing mechanism 3 and a deviation rectifying mechanism 1 for automatically rectifying the deviation when the tape is being wound.

[0029] In this embodiment: The deviation rectifying mechanism 1 includes a workbench 101. On the front and rear sides of the workbench 101, support frames 104 are symmetrically arranged. On one side of each of the two support frames 104, an L-shaped frame 107 is provided. At the upper ends of the two L-shaped frames 107, groove-type photoelectric switches 102 for sensing the degree of tape deviation are fixedly connected.

A guide groove for linearly sliding on the guide rail 103 is opened at the lower part of the support frame 104. The groove-type photoelectric switch 102 judges whether the relative position between the tape and the winding reel 206 deviates during the slitting and winding of the tape. If a deviation occurs, the groove-type photoelectric switch 102 is turned on, making the buzzer 108 alarm to facilitate the staff to perform position correction. The staff operates the deviation rectifying motor 106 to jog, driving the lead screw 105 to rotate, thereby driving the support frame 104 to move in the direction of deviation, making the winding reel 206 in a non-deviated state, and the relative position between the groove-type photoelectric switch 102 and the support frame 104 remains fixed, thus ensuring continuous deviation rectification of the tape winding.

[0030] In this embodiment: The strip dividing mechanism 2 includes a mounting plate 205. Two mounting plates 205 are symmetrically arranged on the front and rear sides of the workbench 101. One end of the mounting plate 205 is provided with a material dividing reel 201. Rotating grooves are provided at the end positions of the two mounting plates 205 where the material dividing reel 201 is located. On the other side of the material dividing reel 201, there is a first guiding roller 202. Both ends of the first guiding roller 202 are respectively rotatably connected between the two mounting plates 205. On the other side of the first guiding roller 202, there is a strip dividing cutter roller 203. Both ends of the strip dividing cutter roller 203 are respectively rotatably connected between the two mounting plates 205. A cutting motor 208 is fixedly arranged at the input end of the strip dividing cutter roller 203. The cutting motor 208 is fixed on the side of the mounting plate 205. The strip dividing cutter roller 203 is sleeved with a cutting tool holder. The cutting tool holder is provided with a positioning pin 210 for fixing on the strip dividing cutter roller 203.

At the upper ends of the two support frames 104, there is a U-shaped groove for placing the winding reel 206. In front of the material dividing reel 201, there is a material dividing motor 207. The material dividing motor 207 is fixed on the mounting plate 205. Gears that mesh with each other are provided at the output end of the material dividing motor 207 and the front end of the material dividing reel 201. In front of the winding reel 206, there is a winding motor 209. The winding motor 209 is fixed on the support frame 104. Gears that mesh with each other are provided at the output end of the winding motor 209 and the front end of the winding reel 206. When starting to divide the tape into strips, the two ends of the material dividing reel 201 are placed into the rotating grooves of the mounting plate 205. The cutting motor 208 is started to drive the strip dividing cutter roller 203 to rotate. The material dividing motor 207 rotates. The gear of the material dividing motor 207 meshes with the gear of the material dividing reel 201, thereby driving the material dividing reel 201 to rotate. The cutting motor 208 drives the strip dividing cutter roller 203 to rotate. After the tape is sent out from the material dividing reel 201, it passes through the first guiding roller 202 and is cut into narrow strips of the required width by the blades of the rotating strip dividing cutter roller 203. After passing through the second guiding roller 204, the divided tape is wound into the winding reel 206. The two ends of the winding reel 206 rotate in the U-shaped grooves of the support frame 104. The gear of the winding reel 206 meshes with the gear of the winding motor 209. When the winding motor 209 rotates, it can drive the winding reel 206 to rotate and wind up the divided tape.

[0031] In this embodiment: The bubble removing mechanism 3 includes a rotating shaft 301. Three rotating seats are equidistantly arranged near the lead screw 105 on the workbench 101, and the rotating seats are arranged along the axial direction of the lead screw 105. A rotating shaft 301 is rotatably connected between the three rotating seats. Two U-shaped frames 302 are arranged between the three rotating seats. The lower ends of the two U-shaped frames 302 both pass through the rotating shaft 301, and the U-shaped frames 302 are rotatably connected to the rotating shaft 301. One pressing roller 303 is rotatably connected to the upper end of each of the two U-shaped frames 302. A cross bar is slidably connected to one side of the two U-shaped frames 302 close to the support frame 104. Two springs 304 are fixed to the lower end of the cross bar. The lower ends of the two springs 304 are fixed to the workbench 101. A guide post 305 fixed to the bottom of the cross bar is arranged inside the spring 304. The lower end of the guide post 305 is slidably connected to the workbench 101. The guide post 305 can only move vertically up and down. The spring 304 is sleeved outside the guide post 305. At this time, the spring 304 can provide a vertically upward force to the cross bar of the U-shaped frame 302. The cross bar can slide on the U-shaped frame 302, so that the upward force provided by the spring 304 can always act on the U-shaped frame 302, so that the pressing roller 303 can always be in close contact with the winding roll 206, squeeze the tape winding part, and eliminate the bubbles generated during winding.

[0032] Working principle: When starting to cut the tape into strips, both ends of the feeding roll 201 are placed in the rotating grooves of the mounting plate 205. The cutting motor 208 is started to drive the strip cutting roller 203 to rotate. The feeding motor 207 rotates. The gear of the feeding motor 207 meshes with the gear of the feeding roll 201, and then drives the feeding roll 201 to rotate. The cutting motor 208 drives the strip cutting roller 203 to rotate. After the tape is fed out from the feeding roll 201, it is cut into narrow strips of the required width by the blades of the rotating strip cutting roller 203 after passing through the first guide roller 202. After passing through the second guide roller 204, the cut tape is wound into the winding roll 206. Both ends of the winding roll 206 rotate in the U-shaped grooves of the support frame 104. The gear of the winding roll 206 meshes with the gear of the winding motor 209. When the winding motor 209 rotates, it can drive the winding roll 206 to rotate and wind the cut tape.

[0033] The groove type photoelectric switch 102 judges whether the relative position between the tape and the winding roll 206 is offset during the tape strip cutting and winding process. If it is offset, the groove type photoelectric switch 102 is turned on to make the buzzer 108 alarm to facilitate the staff to correct the position. The staff operates the deviation correction motor 106 to jog, drives the lead screw 105 to rotate, and then drives the support frame 104 to move in the offset direction, so that the winding roll 206 is in a non-offset state, and the relative position between the groove type photoelectric switch 102 and the support frame 104 remains fixed, so as to ensure continuous deviation correction of the tape winding.

[0034] The guide post 305 can only move vertically up and down. The spring 304 is sleeved outside the guide post 305. At this time, the spring 304 can provide an upward vertical force to the cross bar of the U-shaped frame 302. The cross bar can slide on the U-shaped frame 302, so that the upward force provided by the spring 304 can always act on the U-shaped frame 302, thereby enabling the pressure roller 303 to always closely adhere to the winding reel 206 and extrude the tape winding part to eliminate the bubbles generated during winding.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention.
