Description

Technical Field

[0001] This utility model relates to the technical field of tape production equipment, specifically a tape core cutting device. Background Technology

[0002] Adhesive tape is a rolled product with an inner core at the center. The inner core facilitates convenient and quick self-winding during production, saving many steps compared to tapes without a core. Furthermore, the inner core has good shape and structural stability for rolled products, and can be suspended by threading it through the roll during daily use. The inner core material is a long cylindrical structure. In tape production workshops, the width of the inner core needs to be determined based on the desired bonding width, usually requiring on-site cutting. In existing technologies, workers typically measure manually and cut the core manually using a cutting device. However, manual cutting requires repeated measurements during the cutting process and is prone to errors, resulting in inconsistent inner core widths, affecting subsequent tape winding operations and overall product quality. Therefore, we propose an adhesive tape inner core cutting device. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] A tape core cutting device, such as Figures 1-5 As shown, it includes a frame 1; the frame 1 is provided with a positioning mechanism 2, which can support and position the raw material of the tape core, thereby facilitating the subsequent cutting operation of the tape core.

[0027] Specifically, the positioning mechanism 2 includes a positioning frame 201, which is slidably connected to the frame 1. The positioning frame 201 supports the positioning mechanism 2 and its position can be adjusted to easily control the length of the tape core to be cut, adapting to different cutting requirements. A positioning disc 202 is rotatably connected to the positioning frame 201. The positioning disc 202 has a positioning hole 203 on its side. The positioning hole 203 supports the end of the tape core material. The positioning disc 202 can rotate after cutting, automatically unloading the cut tape core while switching the remaining tape core material to the subsequent positioning hole 203 for support. A support rod 204 is fixedly connected inside the frame 1. The axis of the support rod 204 corresponds to the center of the positioning disk 202. The diameter of the support rod 204 is smaller than the diameter of the positioning hole 203, allowing it to be inserted into the inner core material to support it. Simultaneously, the support rod 204 cooperates with the positioning hole 203 on the side of the positioning disk 202 to support and limit the two ends of the material. A drive block 205 is sleeved on the outside of the support rod 204. A return spring 206 is fixedly connected to the side of the drive block 205. The drive block 205 and the return spring 206 cooperate to drive the material on the support rod 204, causing it to automatically move towards the positioning disk 202 after cutting. At the same time, the return spring 206 elastically presses the material against the inside of the positioning hole 203, improving the stability of the material during the cutting process.

[0028] Furthermore, a collection box 207 is movably connected to the side of the frame 1. The collection box 207 is designed to collect the cut tape cores. The collection box 207 can be easily installed on or removed from the side of the frame 1. A collection port 208 is provided on the side of the frame 1. The bottom of the frame 1 and the bottom of the inner wall of the frame 1 are inclined towards the collection port 208. The inclined bottom and inner wall of the frame 1 allow the cut tape cores to slide into the collection box 207 easily.

[0029] Based on this, a drive rod 209 is slidably connected to the positioning frame 201. The drive rod 209 is vertically inserted through the positioning frame 201 and can drive the positioning frame 201, facilitating operator control of the movement of the positioning frame 201. A positioning groove 210 is provided at the bottom of the machine frame 1. The positioning groove 210 corresponds to the position of the drive rod 209, and the structure of the positioning groove 210 can cooperate with the drive rod 209 to limit the positioning frame 201.

[0030] Example 2

[0031] like Figure 1 , Figure 2 , Figure 4 , Figure 5As shown, based on Embodiment 1, the frame 1 is provided with a cutting mechanism 3; the cutting mechanism 3 can cut the inner core material to a preset length.

[0032] In this embodiment, the cutting mechanism 3 includes an electric push rod 301, which is fixedly connected to the top of the frame 1. A movable frame 302 is fixedly connected to the output end of the electric push rod 301, and a cutting device 303 is fixedly connected to the movable frame 302. The electric push rod 301 can drive the movable frame 302, thereby driving the cutting device 303 to move up and down, so as to realize the cutting operation of the inner core material.

[0033] Furthermore, a support sprocket 304 is rotatably connected to the side of the frame 1, and a chain 305 is sleeved on the outside of the support sprocket 304. A drive sprocket 306 is rotatably connected to the positioning frame 201. The drive sprocket 306 and the chain 305 mesh with each other. The drive sprocket 306 is fixedly connected to the positioning disk 202. The chain 305 can drive the drive sprocket 306, causing the drive sprocket 306 to drive the positioning disk 202 to rotate, thereby realizing the switching operation of the positioning hole 203.

[0034] Furthermore, a groove 307 is provided on the side of the positioning frame 201, and an adjusting frame 308 is slidably connected inside the groove 307. The adjusting frame 308 has a "U"-shaped structure and is located at the bottom of the drive sprocket 306. The U-shaped adjusting frame 308 can cover the top of the drive sprocket 306. A positioning wheel 309 is rotatably connected to the adjusting frame 308 and is rotatably connected to the side of the chain 305. There are two sets of positioning wheels 309, which are symmetrically arranged on the outside of the adjusting frame 308. Each set of positioning wheels 309 has two wheels. The chain 305 passes through the gap between each set of positioning wheels 309, and the position of the chain 305 is adjusted by the positioning wheels 309, allowing the chain 305 to switch between engaging and disengaging with the drive sprocket 306. In addition, the top length of the chain 305 is greater than the distance between the two support sprockets 304, so in the default state, the top of the chain 305 is drooping downwards. The adjusting frame 308 is fixedly connected to the drive rod 209. When the drive rod 209 moves, it can drive the adjusting frame 308 to move synchronously, thereby achieving the manual control effect of the chain 305 and the drive sprocket 306 being engaged.

[0035] It is worth noting that a ratchet 310 is fixedly connected to the side of the support sprocket 304. The ratchet 310 and the support sprocket 304 are concentrically arranged. A transmission rod 311 is fixedly connected to the side of the moving frame 302. A pawl 312 is connected to the side of the transmission rod 311. The pawls 312 are equidistant from each other and mesh with the ratchet 310. The pawls 312 and the ratchet 310 are in a one-way meshing state. Therefore, the moving frame 302 can drive the ratchet 310 when it rises and keep the ratchet 310 stationary when it falls.

[0036] In use, the tape core cutting device of this utility model first places one end of the tape core material to be cut on the outside of the support rod 204 and moves the core material inward. The core material pushes the drive block 205 to move and compresses the return spring 206. Then, the other end of the core material is aligned with the positioning hole 203. After the core material is released, the return spring 206 pushes the core material towards the positioning plate 202 under the action of elasticity, and the other end of the core material abuts against the inside of the positioning hole 203. Next, the drive rod 209 is pulled upward, and the bottom end of the drive rod 209 moves out of the positioning groove 210, and the positioning frame 201 loses its limiting state. At the same time as the drive rod 209 moves upward, the adjusting frame 308 slides along the slide groove 307 and drives the positioning wheel 309 to move. The positioning wheel 309 then drives the chain 305 upward, causing the chain 305 to disengage from the drive sprocket 306. The positioning frame 201 is moved horizontally by the drive rod 209, causing it to move closer to the support rod 204. At this time, the inner core material drives the drive block 205 to move and continuously compresses the return spring 206. After moving to the set position, the drive rod 209 is moved downwards until its bottom end is inside the positioning groove 210. Simultaneously, the adjusting frame 308 moves downwards along the slide groove 307, causing the chain 305 to mesh with the drive sprocket 306. Then, the electric push rod 301 and the cutting device 303 are activated to cut the inner core material. During cutting, the electric push rod 301 drives the moving frame 302 and the transmission rod 311 to move downwards continuously. The pawl 312 on the side of the transmission rod 311 slides on the side of the ratchet 310. At this time, the pawl 312 is disengaged from the ratchet 310, so the downward-moving pawl 312 does not drive the ratchet 310. After the cutting device 303 completes a single cutting operation on the inner core material, the electric push rod 301 drives the moving seat and transmission rod 311 to move upward and reset. At this time, the rising pawl 312 meshes with the ratchet 310 and drives the ratchet 310 to rotate. The ratchet 310 then drives the chain 305 to rotate through the support sprocket 304. The rotating chain 305 then drives the drive sprocket 306 to rotate, and the positioning plate 202 rotates accordingly. The positioning hole 203 on the side of the positioning plate 202 then drives the cut inner core to rotate. After the rotation, the positioning hole 203 rotates from a horizontal state to a downward tilted state, and the inner core inside the positioning hole 203 slides down. The inner core that falls onto the frame 1 slides down the tilted structure into the collection box 207 for collection. During the rotation of the positioning plate 202, the material and the inner core gradually misalign. When the material and the inner core are completely misaligned and separated, the material moves towards the positioning plate 202 under the elastic action of the reset spring 206.When the moving frame 302 rises to the initial position, the positioning plate 202 stops rotating, and the subsequent positioning hole 203 rotates to a horizontal position. Under the elastic action of the return spring 206, the raw material moves into the positioning hole 203, thus facilitating the subsequent cutting operation.
