Description

Technical Field

[0001] This utility model relates to the technical field of adhesive tape production equipment, and in particular to a precision cutting device for adhesive tape production. Background Technology

[0002] Adhesive tape, also known as adhesive strip, is a strip-shaped material made by uniformly coating a substrate such as paper, cloth, or plastic film with an adhesive layer. It utilizes the adhesive's stickiness to connect, fix, or seal the surfaces of objects, serving multiple functions such as bonding, protection, insulation, and marking. There are many types of adhesive tape, commonly including transparent tape, masking tape, cloth tape, and kraft paper tape, which are widely used in packaging, decoration, electronics, medical, and other fields, and are indispensable auxiliary materials in daily life and industrial production.

[0003] In the production process of adhesive tape, in order to accurately cut the whole roll of adhesive tape to the preset size, the existing precision cutting equipment often faces a key challenge: due to the lack of an effective pressing mechanism, the adhesive tape is prone to shaking during feeding and cutting. This shaking will cause uneven cut surfaces, which will seriously affect the appearance and use of the adhesive tape, such as reduced alignment accuracy and uneven edges. Therefore, improvements are needed. Utility Model Content

[0004] One objective of this invention is to provide a precision cutting device for adhesive tape production. This invention addresses the key challenge faced by existing precision cutting devices in the adhesive tape production process, as mentioned in the background: due to the lack of an effective pressing mechanism, the adhesive tape is prone to shaking during feeding and cutting. This shaking leads to uneven cut surfaces, seriously affecting the aesthetics and performance of the adhesive tape.

[0005] A precision cutting device for producing adhesive tape according to an embodiment of the present invention includes:

[0006] Support components include a processing table and a positioning groove on the top of the processing table for positioning the entire roll of adhesive tape;

[0007] A pressing mechanism, installed on the top of the processing table in the support assembly, is used to convey adhesive tape of different diameters. The pressing mechanism includes conveying rollers rotatably mounted on both sides of the top of the processing table via a first rotating shaft, and adjusting frames also mounted on the top of the processing table. A conveyor belt is driven between the two conveying rollers. The conveyor belt is connected to the conveying rollers via a first driving assembly to convey the entire roll of adhesive tape. A second rotating shaft rotatably mounted on the processing table is fixed inside the adjusting frame. A tensioning roller is rotatably mounted inside the adjusting frame at one end that is in contact with the conveyor belt. The adjusting frame is connected to the processing table via a reset assembly to achieve elastic pressing and conveying.

[0008] The cutting mechanism, installed above the processing table in the support assembly, is used to cut the entire roll of adhesive tape into sections.

[0009] Preferably, support legs are fixedly installed at the four corners of the bottom of the processing table.

[0010] Preferably, the first drive assembly includes a first gear fixed to the bottom of the first rotating shaft on the right side, and a second gear is provided for meshing and transmission between the two first gears, the second gear being fixedly disposed at the output end of the first motor.

[0011] Preferably, the first motor is fixedly mounted to the processing table via a first bracket.

[0012] Preferably, the reset assembly includes a positioning rod fixed to the upper part of the inside of the adjustment frame and a limiting rod fixed to the top of the processing table. A torsion spring is movably arranged on the outside of the positioning rod. One end of the torsion spring is engaged with the second rotating shaft, and the other end of the torsion spring is engaged with the limiting rod.

[0013] Preferably, the cutting mechanism includes an eccentric turntable symmetrically rotating on the top of the processing table and a limiting seat fixed to the top of the processing table. A rotating cylinder is movably arranged on the outer side of the eccentric turntable, and a movable cylinder is movably arranged on the outer side of the rotating cylinder through a bearing seat. A detachable cutting blade is fixedly arranged at one end of the outer side of the movable cylinder, and a guide seat is fixedly arranged at the other end of the outer side of the movable cylinder. A guide rod located inside the limiting seat is fixedly arranged on one side of the guide seat. The cutting blade is connected to the eccentric turntable through a second drive assembly to cut the entire roll of adhesive tape. A collection box is installed at the cutting and unloading end of the processing table.

[0014] Preferably, the eccentric turntable is located at the discharge end of the main conveyor belt of the pressing mechanism.

[0015] Preferably, the second drive assembly includes a third gear fixed at the center of the bottom of the eccentric turntable, a fourth gear meshing between the two third gears, the fourth gear being fixedly mounted at the output end of the second motor, and the second motor being fixedly mounted to the processing table via a second bracket.

[0016] The beneficial effects of this utility model are:

[0017] This invention effectively avoids the problem of uneven cutting caused by the lack of an effective pressing mechanism by setting a pressing mechanism. In use, the positioning groove on the top of the processing table is used to initially position the entire strip of adhesive tape. Then, the first motor in the first drive assembly drives the meshing transmission between the second gear and the first gear, so that the conveyor roller shaft drives the conveyor belt to achieve the transmission effect. At this time, the entire strip of adhesive tape will be conveyed under the clamping of the left and right sets of conveyor belts. Since the conveyor belt is equipped with a flexible pressing assembly consisting of an adjusting frame, a second rotating shaft, a positioning frame, a limiting rod and a tensioning roller shaft, when conveying strips of adhesive tape of different diameters, after the tensioning roller shaft is subjected to the tension of the entire strip of adhesive tape, the tensioning roller shaft drives the adjusting frame to rotate and squeeze the torsion spring. In this way, the conveying of strips of adhesive tape of different diameters can be completed. By using multiple sets of pressing assemblies to apply uniform and adjustable pressure to the adhesive tape, it can effectively prevent the adhesive tape from shaking and shifting during the conveying process, and ensure the accuracy and stability of the cutting.

[0018] This invention effectively avoids the problem of insufficient cut flatness through its cutting mechanism. In use, the entire strip of adhesive tape is moved to the cutting blade of the cutting mechanism by the material pressing mechanism. The second motor drives the fourth gear and the third gear to mesh and rotate, causing the eccentric turntable to rotate. At this time, a movable cylinder connected to the eccentric shaft at the top of the eccentric turntable is installed, which drives the cutting blade to perform linear displacement to form a periodic cutting action, so as to cut the entire strip of adhesive tape proportionally. This not only achieves continuous and precise cutting of the adhesive tape, but also ensures the stability and consistency of the cutting blade during the cutting process through the guide structure, thereby greatly improving the production efficiency of the adhesive tape.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0026] refer to Figure 1-4 A precision cutting device for producing adhesive tape, comprising:

[0027] Support component 1 includes a processing table 101 and a positioning groove 103 opened on the top of the processing table 101 for positioning the whole roll of adhesive tape.

[0028] The pressing mechanism 2, installed on the top of the processing table 101 in the support assembly 1, is used to convey adhesive tape of different diameters. The pressing mechanism 2 includes conveying rollers 202 rotatably mounted on both sides of the top of the processing table 101 via a first rotating shaft 201, and adjusting frames 204 both mounted on the top of the processing table 101. A conveyor belt 203 is driven between the two conveying rollers 202. The conveyor belt 203 is connected to the conveying rollers 202 via a first drive assembly to convey the entire roll of adhesive tape. A second rotating shaft 205, rotatably mounted on the processing table 101, is fixed inside the adjusting frame 204. A tensioning roller 209 is rotatably mounted inside the adjusting frame 204 at one end that is in contact with the conveyor belt 203. The adjusting frame 204 is connected to the processing table 101 via a reset assembly to achieve elastic pressing and conveying. The reset assembly includes a positioning rod 207 fixed to the upper end of the adjusting frame 204. A torsion spring 208 is movably installed on the outer side of the positioning rod 207, which is fixed to the top of the processing table 101 and the limiting rod 206. One end of the torsion spring 208 is engaged with the second rotating shaft 205, and the other end of the torsion spring 208 is engaged with the limiting rod 206. The first drive assembly is used to transport the entire strip of adhesive tape under the clamping of the left and right conveyor belts. Since the conveyor belt is equipped with a flexible pressing assembly consisting of an adjusting frame, a second rotating shaft, a positioning frame, a limiting rod, and a tension roller, when transporting strips of adhesive tape of different diameters, the tension roller is subjected to the tension of the entire strip of adhesive tape. The tension roller drives the adjusting frame to rotate and squeeze the torsion spring. In this way, the entire strip of adhesive tape of different diameters can be transported. By using multiple pressing assemblies to apply uniform and adjustable pressure to the adhesive tape, the shaking and deviation of the adhesive tape during the transport process can be effectively prevented, ensuring the accuracy and stability of the cutting.

[0029] The cutting mechanism 3, installed above the processing table 101 in the support assembly 1, is used to cut the entire roll of adhesive tape into segments. The cutting mechanism 3 includes an eccentric turntable 301 that rotates symmetrically on the top of the processing table 101, and a limiting seat 308 fixed to the top of the processing table 101. A rotating cylinder 302 is movably arranged on the outer side of the eccentric turntable 301. A movable cylinder 304 is movably arranged on the outer side of the rotating cylinder 302 through a bearing seat 303. A detachable cutting blade 305 is fixedly arranged at one end of the outer side of the movable cylinder 304, and a guide seat 306 is fixedly arranged at the other end of the outer side of the movable cylinder 304. A guide rod 307 is fixedly installed inside the limit seat 308 for guiding and sliding. The cutting blade 305 is connected to the eccentric turntable 301 through the second drive assembly to cut the whole roll of adhesive tape. A collection box 4 is installed at the cutting end of the processing table 101. The second drive assembly drives the eccentric turntable to rotate. At this time, a movable cylinder connected to the eccentric shaft at the top of the eccentric turntable is installed. The movable cylinder drives the cutting blade to make linear displacement to form a periodic cutting action, so as to cut the whole strip of adhesive tape proportionally. This not only realizes the continuous and precise cutting of the adhesive tape.

[0030] Example 1: Support legs 102 are fixedly installed at the four corners of the bottom of the processing table 101 to ensure stable placement of the equipment. The first drive assembly includes a first gear 211 fixed to the bottom of the first rotating shaft 201 on the right side. A second gear 212 is meshed between the two first gears 211. The second gear 212 is fixedly installed at the output end of the first motor 213. The first motor 213 is fixedly installed to the processing table 101 through the first bracket 214. The first motor in the first drive assembly drives the meshing transmission between the second gear and the first gear, so that the conveyor roller shaft drives the conveyor belt to achieve the transmission effect.

[0031] Example 2: The eccentric turntable 301 is located at the discharge end of the main conveyor belt 203 of the pressing mechanism 2. The second drive assembly includes a third gear 309 fixed at the bottom center of the eccentric turntable 301. A fourth gear 310 is meshed between the two third gears 309. The fourth gear 310 is fixed at the output end of the second motor 311. The second motor 311 is fixed to the processing table 101 through the second bracket 312. The second motor drives the fourth gear to mesh with the third gear and rotate, so that the eccentric turntable rotates. At this time, a movable cylinder connected by a rotating cylinder and a bearing seat is installed at the position of the eccentric shaft at the top of the eccentric turntable. The movable cylinder drives the cutting blade to perform linear displacement to form a periodic cutting action, so as to cut the entire strip of adhesive tape proportionally.

[0032] Working principle: The entire roll of adhesive is positioned in the positioning groove 103 of the processing table 101. The first motor 213 is started to drive the second gear 212 to mesh with the first gears 211 on both sides, which drives the two sets of conveyor rollers 202 fixed to the first rotating shaft 201 to rotate synchronously, so that the conveyor belt 203 clamps the adhesive roll for linear conveying. When the diameter changes during the conveying of different adhesive rolls, the adjusting frame 204 rotates around the second rotating shaft 205 under the tension of the adhesive, which drives the tension roller 209 to press the surface of the conveyor belt 203. At this time, the torsion spring 208 on the positioning rod 207 generates a reverse torque through the limiting rod 206, so that the adjusting frame 204 adaptively adjusts the angle and maintains the conveyor belt 203. With a constant tension of 3, the tape is smoothly conveyed to the cutting station via conveyor belt 203. The second motor 311 is started to drive the fourth gear 310 to mesh with the third gears 309 on both sides. The eccentric motion of the eccentric turntable 301 pushes the movable cylinder 304 along the guide rod 307 in the limiting seat 308 to make reciprocating linear motion, which drives the cutting blade 305 to cut vertically and return at a uniform speed, forming a periodic cutting action. Each time the cutting blade 305 cuts, the sliding constraint of the guide rod 307 in the limiting seat 308 ensures the straightness accuracy of the cutting trajectory, and the entire tape is evenly cut into tapes of the same width. Finally, the cut tape will fall into the collection box.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
