Description

Technical Field

[0001] This utility model relates to the technical field of tape slitting devices, and in particular to a slitting device for producing PET substrate adhesive tape. Background Technology

[0002] A slitting device for PET adhesive tape production is a machine used to cut large rolls of PET adhesive tape into smaller rolls or different sizes. This process is called "slitting" or "rewinding," and its main purpose is to divide the master roll of tape into sizes more suitable for subsequent processing or use according to requirements.

[0003] The utility model patent with announcement number CN219027603U discloses a tape slitting device. The key technical features are as follows: it includes an L-shaped bracket, with a tape unwinding mechanism on the top right side wall of the L-shaped bracket. A pair of sliding holes are provided in the middle of the L-shaped bracket, and sliding rods are installed inside the sliding holes. A left connecting rod is installed at the left end of each sliding rod, and a right connecting rod is installed at the right end. A left pressure block is provided between the two sliding holes, and a groove is provided on the left pressure block. A cylinder pushes the left connecting rod to the left, and the left connecting rod drives the right connecting rod to the left via the sliding rod. During the movement, the right pressure block contacts the left pressure block first. At this time, the tape is clamped by the right and left pressure blocks. The cutting blade continues to move, passing through the rectangular through-hole of the right pressure block and inserting into the groove to cut the tape. Because the tape at both ends is fixed by the right and left pressure blocks, the tape is kept stable during cutting, resulting in a smooth cutting surface and good cutting effect.

[0004] Regarding the above-mentioned issues, the following technical defects exist: PET-based adhesive tape is an adhesive tape with polyester film as its base material. PET tape has high strength, heat resistance, and good electrical insulation properties. The slitting equipment used in the production of PET-based adhesive tape is a device used to cut large rolls of PET-based adhesive tape into different specifications and sizes. However, during the slitting process, it was found that the cut tapes adhered to each other, which affected the speed at which workers could remove the tapes from the slitting equipment.

[0005] Therefore, it is necessary to provide a new slitting device for the production of PET substrate adhesive tape to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies where, during the slitting process of film rolls using slitting equipment, the slitting tapes tend to stick together, which affects the speed at which workers can remove the tapes from the slitting equipment.

[0007] To solve the above-mentioned technical problems, this utility model provides a slitting device for producing PET substrate adhesive tape, comprising: a slitting equipment body, a slitting device installed on the inner wall of the slitting equipment body, an adhesive tape body installed on the inner wall of the slitting equipment body, an adjusting device provided on one side of the slitting equipment body, the adjusting device including a support plate, the support plate being slidably connected to one side of the slitting equipment body, two assembly rods threaded through the inner wall of the support plate, both assembly rods being threaded through the inner wall of the slitting equipment body, a cylinder fixedly connected to one end of the support plate, an adjusting plate fixedly connected to the output end of the cylinder, sliding rods fixedly connected to both ends of the adjusting plate near the cylinder, both sliding rods slidingly penetrating the inner wall of the support plate, a limit block fixedly connected to one end of the arc surface of each sliding rod, and a plurality of partition blocks fixedly connected to the side of the adjusting plate away from the sliding rods, the plurality of partition blocks being evenly distributed on one side of the adjusting plate.

[0008] The effects achieved by the above components are as follows: The PET substrate adhesive tape body is an adhesive tape with polyester film as the substrate. The PET tape body has high strength, heat resistance and good electrical insulation properties. The slitting equipment body for producing the PET substrate adhesive tape body is a device used to cut large rolls of PET substrate tape body into different specifications and sizes. However, it was found that during the slitting process of the tape roll by the slitting equipment body, the cut tape bodies will stick together. This also affects the speed at which workers can remove the tape bodies from the slitting equipment body. At this time, the slitting equipment body can be separated by an adjustment device, so as to facilitate workers to remove the tape bodies from the slitting equipment body and improve the workers' work efficiency.

[0009] Preferably, a first spring is fixedly connected to one side of the limiting block, the inner wall of the first spring is slidably connected to the arc surface of the sliding rod, and an abutment ring is fixedly connected to the end of the first spring away from the limiting block, the inner wall of the abutment ring is slidably connected to the arc surface of the sliding rod.

[0010] The effect achieved by the above components is as follows: when the sliding rod slides on the support plate and causes the limiting block to come into contact with the support plate, the abutment ring installed on the first spring can prevent the limiting block from directly contacting the support plate, thereby protecting the surface of the limiting block through the abutment ring.

[0011] Preferably, an arc-shaped plate is fixedly connected to both sides of the separator block, and the cross-sectional dimensions of the arc-shaped plate are the same as those of the separator block.

[0012] The effect achieved by the above components is that when the separator block comes into contact with the side of the cut tape body, the arc-shaped plate installed on the separator block can improve the efficiency of the contact between the separator block and the tape body, and the arc-shaped plate can make it easier for the separator block and the tape body to come into contact.

[0013] Preferably, the sliding rod is a titanium alloy rod.

[0014] The effect achieved by the above components is that the sliding rod made of titanium alloy has a relatively hard surface, and the rod is less likely to deform after long-term use, resulting in a better service life.

[0016] The effect achieved by the above-mentioned components is that when the tape body is cut by the slitting equipment body, the auxiliary device can collect the excess debris generated during the slitting process, so as to avoid the debris from falling on the slitting equipment body and making it difficult to clean the surface of the slitting equipment body later. The auxiliary device can improve the cleanliness of the surface of the slitting equipment body.

[0017] Preferably, a guide block is fixedly connected to one end of the insertion rod away from the arc surface of the force-applying block, and the guide block is funnel-shaped.

[0018] The effect achieved by the above components is as follows: when the insertion rod comes into contact with the inner wall of the side plate under the action of the second spring, the guide block installed on the insertion rod can increase the speed of connection between the insertion rod and the inner wall of the side plate, thereby improving the efficiency of connection between the insertion rod and the inner wall of the side plate through the guide block.

[0019] Preferably, the side of the force-adding block is provided with an auxiliary groove.

[0020] The effect achieved by the above components is that when the lever is used to pull the rod, the auxiliary groove on the lever makes it easier for workers to use the lever, and the auxiliary groove improves the convenience of using the lever.

[0021] Compared with related technologies, the slitting device for producing PET substrate adhesive tape provided by this utility model has the following advantages:

[0022] This utility model provides a slitting device for producing PET substrate adhesive tape.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0032] Please see Figures 1 to 5 The present invention provides a slitting device for producing PET substrate adhesive tape, comprising: a slitting device body 1, a slitting device 4 installed on the inner wall of the slitting device body 1, an adhesive tape body 5 installed on the inner wall of the slitting device body 1, an adjusting device 2 provided on one side of the slitting device body 1, and an auxiliary device 3 provided on the inner wall of the slitting device body 1.

[0033] In the embodiments of this utility model, please refer to Figure 2 and Figure 3The adjusting device 2 includes a support plate 201, which is slidably connected to one side of the slitting equipment body 1. Two assembly rods 202 are threaded through the inner wall of the support plate 201, and both assembly rods 202 are threaded through the inner wall of the slitting equipment body 1. A cylinder 203 is fixedly connected to one end of the support plate 201, and an adjusting plate 204 is fixedly connected to the output end of the cylinder 203. Sliding rods 206 are fixedly connected to both ends of the adjusting plate 204 near the cylinder 203. Both sliding rods 206 slide through the inner wall of the support plate 201. A limit block 207 is fixedly connected to one end of the arc surface of each sliding rod 206. Several... Several separator blocks 205 are evenly distributed on one side of the adjusting plate 204. The PET substrate adhesive tape body 5 is an adhesive tape with polyester film as its substrate. The PET tape body 5 has high strength, heat resistance, and good electrical insulation properties. The slitting equipment body 1 for producing the PET substrate adhesive tape body 5 is a device used to cut large rolls of PET substrate adhesive tape body 5 into different specifications and sizes. However, during the slitting process of the tape roll by the slitting equipment body 1, it was found that the cut tape bodies 5 would stick together, which affected the speed at which subsequent workers could remove the tape bodies 5 from the slitting equipment body 1. At this time, the adjusting device 2 can be used to adjust the speed... The slitting equipment body 1 is divided after slitting, making it easier for workers to remove the tape body 5 from the slitting equipment body 1, thus improving worker efficiency. A first spring 208 is fixedly connected to one side of the limiting block 207. The inner wall of the first spring 208 is slidably connected to the arc surface of the sliding rod 206. An abutment ring 209 is fixedly connected to the end of the first spring 208 away from the limiting block 207. The inner wall of the abutment ring 209 is slidably connected to the arc surface of the sliding rod 206. When the sliding rod 206 slides on the support plate 201 and causes the limiting block 207 to contact the support plate 201, the abutment ring 209 installed on the first spring 208 can prevent the limiting block 207 from directly contacting the support plate 201. Thus, the surface of the limiting block 207 can be protected by the abutment ring 209. Both sides of the separator block 205 are fixedly connected with arc plates 210. The cross-sectional dimensions of the arc plates 210 are the same as those of the separator block 205. When the separator block 205 comes into contact with the side of the cut tape body 5, the arc plates 210 installed on the separator block 205 can improve the efficiency of the contact between the separator block 205 and the tape body 5. The arc plates 210 can make it easier for the separator block 205 and the tape body 5 to come into contact. The sliding rod 206 is a titanium alloy rod. The surface of the sliding rod 206 made of titanium alloy is relatively hard. The sliding rod 206 is also less likely to deform after long-term use, and has a better service life.

[0034] In the embodiments of this utility model, please refer to Figure 4 and Figure 5The auxiliary device 3 includes a storage box 31, which is movably connected to the inner wall of the slitting device body 1. Two handles 32 are fixedly connected to one side of the storage box 31, and a side plate 33 is fixedly connected to one end of the storage box 31. Two insert rods 34 are slidably connected to the inner wall of the side plate 33, and both insert rods 34 slide through the inner wall of the slitting device body 1. The ends of the two insert rods 34 away from the arc surface of the side plate 33 are fixedly connected to the same force-applying block 36. A second spring 35 is slidably connected to the arc surface of the insert rod 34. The two ends of the second spring 35 are fixedly connected to the force-applying block 36 and one side of the slitting device body 1, respectively. When the slitting device body 1 is used to slit the tape body 5, the auxiliary device 3 can collect the excess debris generated during the slitting process to prevent the debris from scattering on the slitting device. On the main body 1 of the equipment, it is difficult to clean the surface of the slitting equipment body 1 in the future. The auxiliary device 3 can improve the cleanliness of the surface of the slitting equipment body 1. The end of the insertion rod 34 away from the arc surface of the force block 36 is fixedly connected to the guide block 37. The guide block 37 is funnel-shaped. When the insertion rod 34 contacts the inner wall of the side plate 33 under the drive of the second spring 35, the guide block 37 installed on the insertion rod 34 can increase the speed of the connection between the insertion rod 34 and the inner wall of the side plate 33. Thus, the efficiency of the connection between the insertion rod 34 and the inner wall of the side plate 33 can be improved through the guide block 37. The side of the force block 36 is provided with an auxiliary groove 38. When the force block 36 is used to pull the insertion rod 34, the auxiliary groove 38 on the force block 36 can facilitate the use of the force block 36 by the worker. The auxiliary groove 38 can improve the convenience of using the force block 36.

[0035] The working principle of the slitting device for producing PET substrate adhesive tape provided by this utility model is as follows: The assembly rod 202 is rotated within the support plate 201, fixing the support plate 201 onto the slitting equipment body 1 via the assembly rod 202. At this time, the tape body 5 can be slitted using the slitting equipment body 1 and the slitter 4. During the slitting process, the cylinder 203 installed on the support plate 201 is activated. The movement of the cylinder 203 drives the adjusting plate 204 to move via its output end. The movement of the adjusting plate 204 drives the sliding rod 206 to move on the support plate 201 towards the tape body 5. This allows the separating block 205 to connect with the tape body 5 at the slitting point, thus completing the separation.

[0036] Pulling the insertion rod 34 by the force block 36 causes the second spring 35 to stretch. At this time, the storage box 31 can be placed into the slitting equipment body 1 using the handle 32, and the angle between the inner wall of the side plate 33 and the insertion rod 34 can be aligned. Then, the force block 36 can be released, and the second spring 35 will return to its original position, causing the insertion rod 34 to contact the inner wall of the side plate 33. This contact between the insertion rod 34 and the inner wall of the side plate 33 fixes the storage box 31 to the slitting equipment body 1, allowing the storage box 31 to collect the debris generated by slitting the tape body 5.

[0037] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
