Detailed implementation mode

[0038] The following combines with Figure 1-13 to describe the present utility model in detail.

[0039] The utility model relates to a feeding and positioning device for tape production, as Figure 1 and Figure 2 shown, which includes a feeding device 10. The feeding device 10 includes a feeding roller 101. A positioning device is provided on one side of the feeding device 10. The positioning device includes at least two relatively arranged frames 20, and a winding roller 201 is arranged between the two opposite frames 20. During production, the tape is conveyed through the feeding roller 101 and wound around the winding roller 201. A pressing device 30 is provided on one side of the frame 20. The pressing device 30 includes a mounting seat 301, and the mounting seat 301 is connected to the frame 20. A push plate 302 is movably arranged on the side of the mounting seat 301 facing the winding roller 201, and a first elastic member 308 is abutted between the push plate 302 and the side of the mounting seat 301 facing the winding roller 201. During winding, the push plate 302 abuts against the circumferential surface of the tape on the winding roller 201, and the tape is prevented from loosening or uneven glue coating by squeezing. As the winding thickness of the tape increases, the push plate 302 is squeezed, and the push plate 302 moves towards the mounting seat 301 as the tape is wound, and the first elastic member 308 is compressed.

[0040] In this embodiment, a limiting device is provided on the surface of the push plate 302 close to the winding roller 201, as Figure 4 shown. The limiting device abuts against both side surfaces of the tape to ensure that the tape does not shift during winding. Further, the limiting device includes a first limiting plate 303 and a second limiting plate 304. The first limiting plate 303 and the second limiting plate 304 respectively abut against both side surfaces of the tape. Among them, the first limiting plate 303 is in guide pair cooperation with the push plate 302 and can move on the push plate 302 to adapt to tapes of different widths. Specifically, during winding, the limiting device contacts the tape first to achieve positioning in the width direction until the thickness of the tape roll increases and fits with the push plate 302, and then the push plate 302 squeezes the tape to start positioning the circumferential surface of the tape. After that, the push plate 302 moves following the winding of the tape.

[0041] In this embodiment, as Figure 9 and Figure 10 shown, a first guide groove 305 parallel to the axial direction of the winding roller 201 is provided on the surface of the push plate 302 facing the winding roller 201, and a movable rod 3051 is arranged in the first guide groove 305. A first slider 3031 extends from the surface of the first limiting plate 303 facing the first guide groove 305, and the first slider 3031 is movably arranged in the first guide groove 305; the first slider 3031 is provided with a first through hole 3032 adapted to the movable rod 3051, and the first limiting plate 303 is movably connected to the movable rod 3051 through the first through hole 3032, so that the first limiting plate 303 can move along the movable rod 3051.

[0042] In this embodiment, the push plate 302 further includes a second guide groove 306 parallel to the first guide groove 305, within which a screw 3061 is disposed. A second slider 3041 extends from the side of the first limit plate 303 facing the second guide groove 306, and the second slider 3041 moves within the second guide groove 306. The second slider 3041 includes a second through-hole 3042 adapted for the screw 3061, which is threadedly engaged with the screw 3061. By manipulating the screw 3061, the position of the first limit plate 303 can be adjusted to match the width of the tape on the take-up roller 201. In this embodiment, the first and second guide grooves 305, 306 are not coplanar with the take-up roller 201. During the take-up process, neither the first or second guide grooves 305, 306 come into contact with the tape on the take-up roller 201.

[0043] In this embodiment, Figure 6 and Figure 8 As shown, the mounting base 301 includes a mounting plate 3011 connected to the two frames 20. A positioning member 3023 is provided at the bottom of the push plate 302, and the mounting base 301 is provided with a groove 3013 that slidably fits the positioning member 3023. As the tape increases in thickness during winding, the push plate 302 always abuts the tape and, with the positioning member 3023 cooperating with the groove 3013, moves along the groove 3013. Furthermore, the mounting base 301 also includes a fixed plate 3012 perpendicularly connected to the mounting plate 3011. A guide rod 307 is provided on the side of the push plate 302 away from the winding roller 201. The guide rod 307 is movably inserted into the fixed plate 3012. A first elastic member 308 is sleeved on the outside of the guide rod 307, with one end abutting the fixed plate 3012 and the other end abutting the push plate 302. When the tape is wound, the first elastic member 308 is gradually compressed and the push plate 302 moves toward the fixed plate 3012; when the material is wound and the winding roller 201 is removed, the first elastic member 308 returns to its original state, and the push plate 302 moves to its original position along the groove 3013 under the action of the elastic force.

[0044] In this embodiment, Figure 11-13 As shown, one end of the push plate 302 is provided with a mounting hole 3024 that is connected to the second guide groove 306, and a bearing 3021 that matches it is provided in the mounting hole 3024. The screw rod 3061 is fixed in the bearing 3021 and one end thereof is exposed to the outside of the push plate 302. A handle 309 is provided at the end of the screw rod 3061 that is located outside the bearing 3021. By turning the handle 309, the screw rod 3061 can be rotated, thereby adjusting the position of the second limit plate 304. The push plate 302 is provided with a fixing hole 3022 on one side of the bearing 3021, and a latch member 40 is movably provided in the fixing hole 3022. As shown Figure 7As shown, the handle 309 is provided with a fixed convex block 3091 along its radial direction. The fixed convex block 3091 is provided with a movable hole 3092. The position of the movable hole 3092 corresponds to that of the fixed hole 3022. The pin member 40 moves in the fixed hole 3022, and the other end passes through the movable hole 3092. Specifically, when the pin member 40 enters the fixed hole 3022, the lead screw 3061 is fixed to complete the adjustment. The distance between the first limiting plate 303 and the second limiting plate 304 is equal to the width of the tape. During adjustment, first pull out the pin member 40 from the fixed hole 3022, and then rotate the handle 309 to rotate the lead screw 3061.

[0045] In this embodiment, a transmission member 202 is passed through the top of the frame 20. As Figure 3 and Figure 5 shown, one end of the transmission member 202 is connected to a motor 203, and the other end is detachably connected to the winding roller 201. Under the operation of the motor 203, the transmission member 202 drives the winding roller 201 to complete the material winding. A second elastic member 205 is sleeved outside the transmission member 202. One end of the second elastic member 205 abuts against the frame 20, and the other end abuts against the transmission member 202. A rotating member 204 is further provided at the top of the frame 20. The rotating member 204 is connected to one end of the winding roller 201 away from the transmission member 202 and can cooperate with the winding roller 201 to complete rotation during winding. Specifically, mounting members 2011 are provided at both ends of the winding roller 201. The transmission member 202 and the rotating member 204 are both provided with docking grooves 2021 adapted to the mounting members 2011. The cooperation between the mounting members 2011 and the docking grooves 2021 ensures the stability of the operation of the winding roller 201. During use, first push the transmission member 202 outwards to compress the second elastic member 205, then place the winding roller 201 between the transmission member 202 and the rotating member 204 to ensure that the mounting member 2011 is docked with the docking groove 2021 on the rotating member 204, and then release the transmission member 202. Under the elastic force of the second elastic member 205, the mounting member 2011 on the transmission member 202 is docked with the docking groove 2021 to complete the installation. During disassembly, push the transmission member 202 outwards, the second elastic member 205 is compressed, and the mounting member 2011 disengages from the groove 3013 on the rotating member 204, and the winding roller 201 can be removed from the frame 20.
