Description

Technical Field

[0001] This utility model belongs to the field of easy-tear tape production technology, specifically relating to an easy-tear tape synchronous feeding device. Background Technology

[0002] Easy-tear tape is short for easy-tear adhesive tape. It is commonly used in the adhesive packaging of items and letters, which makes the items and letters highly secure during transportation and can be quickly torn when needed. Easy-tear tape requires a feeding device during processing. However, in order to reduce the amount of stretching deformation of the easy-tear tape, it is generally stretched during feeding and then attached to the film.

[0003] Utility model patent CN216511718U discloses a synchronous feeding device for easy-tear tape, including support columns, a worktable, a mounting plate, an easy-tear tape reel, a film reel, an anti-wrinkle stretching mechanism, a film conveying mechanism, an auxiliary mechanism, an easy-tear tape, a tool box, film, and an output wheel. Four support columns are bolted to the lower part of the worktable, and the upper rear end of the worktable is bolted to the mounting plate. An easy-tear tape reel is mounted on a rotating shaft on one side of the front of the mounting plate. The use of a flanged deep groove ball bearing ensures the rotation of the roller, and a baffle prevents the film from detaching from the roller during conveying, thus preventing irregular entanglement and ensuring normal film conveying, meeting the usage requirements. The cooperation between the guide rod and the adjusting screw moves the support base, thereby adjusting the friction and contact area between the auxiliary wheel and the easy-tear tape reel or film reel, which helps control the rotation speed of the easy-tear tape reel or film reel, preventing it from being too slow or too fast and affecting the working condition.

[0004] However, the above-mentioned existing technical solutions still have the following shortcomings: 1. The auxiliary mechanism has low adjustment efficiency. The friction between the auxiliary wheel and the roller is controlled by manually rotating the adjustment handle. Repeated adjustments are required and it is difficult to maintain stable pressure. 2. Although the device has a baffle to prevent the film from falling off the roller, it does not mention how to enhance the friction between the roller and the film, which may cause the film to slip or fall off when it is conveyed at high speed.

[0026] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0027] Please see Figures 1 to 5 As shown, this utility model embodiment provides an easy-tear tape synchronous feeding device, including an installation mechanism 1. The installation mechanism 1 includes an installation platform 101, a support plate 102 fixed on the surface of the installation platform 101, an installation plate 103 fixed on the surface of the support plate 102, an easy-tear tape reel 104, a film reel 105 and multiple output wheels 106 mounted on the surface of the installation plate 103, a controller 107 fixed on the surface of the support plate 102, and an auxiliary mechanism 2, a tension adjustment mechanism 3 and a film conveying mechanism 4 provided on the surface of the installation plate 103. The auxiliary mechanism 2 includes an installation shell 201, a lead screw 202 threaded through the surface of the installation shell 201, a first movable plate 203 rotatably connected to the bottom end of the lead screw 202, a spring 204 fixed on the surface of the first movable plate 203, a C-shaped shell 205 fixed to one end of the spring 204, and three pressure rollers 206 rotatably connected to the inner wall of the C-shaped shell 205, the three pressure rollers 206 being arranged in an arc shape.

[0028] Specifically, in this embodiment, the mounting plate 103 integrates an easy-tear tape reel 104, a film reel 105, and an output wheel 106, and the controller 107 coordinates the operation of each mechanism; in the auxiliary mechanism 2, the rotating screw 202 pushes the first movable plate 203 to press down the spring 204, and the spring 204 drives the C-shaped shell 205 and three arc-shaped pressure rollers 206 to contact the surface of the reel. The rolling friction of the pressure rollers 206 provides adaptive pressure, and the pressure range of the spring 204 can be preset by combining the screw 202 and the spring 204. The arc distribution of the three pressure rollers 206 expands the contact area, avoids pressure concentration that causes film displacement, ensures constant pressure under different roll diameters, and reduces the frequency of manual intervention.

[0029] Please see Figures 1 to 5 As shown, the tension adjustment mechanism 3 includes multiple first electric push rods 301 and multiple movable frames 302. The first electric push rods 301 are fixedly connected to the surface of the mounting plate 103. Tension sensors 303 are mounted on the surface of the movable frames 302. A rotating roller 304 is rotatably connected to the surface of the tension sensor 303. A connecting shell 305 is rotatably connected to the surface of the rotating roller 304. One end of the first electric push rod 301 is fixedly connected to the top of the connecting shell 305. Specifically, in this embodiment, the tension adjustment mechanism 3 pushes the connecting shell 305 and the rotating roller 304 to move through the first electric push rods 301. The tension sensor 303 monitors the tension of the tear-off tape in real time and feeds it back to the controller 107 to adjust the extension and retraction of the first electric push rods 301 and dynamically control the position of the rotating roller 304 to maintain constant tension, avoiding excessive tightness or looseness that could cause the tear-off tape to break or wrinkle. This mechanism significantly improves the uniformity of tear-off tape stretching and is suitable for high-speed continuous feeding scenarios.

[0030] Please see Figures 1 to 5 As shown, the film conveying mechanism 4 includes two mounting frames 401, which are fixedly connected to the surface of the mounting plate 103. A second electric push rod 402 is fixed to the surface of the mounting frame 401. One end of the second electric push rod 402 passes through the mounting frame 401 and is fixed to a second movable plate 403. A pressure sensor 404 is fixed to the surface of the second movable plate 403, and a first wheel frame 405 is fixed to the surface of the pressure sensor 404. A second wheel frame 407 is provided on one side of the inner wall of the mounting frame 401. Conveying rollers 408 are rotatably connected to the surfaces of both the first wheel frame 405 and the second wheel frame 407. Specifically, in this embodiment, the second electric push rod 402 pushes the second movable plate 403 and the first wheel frame 405 to move. The pressure sensor 404 detects the pressing force of the conveying roller 408 on the film. The controller 107 adjusts the stroke of the second electric push rod 402 according to the feedback to prevent damage or slippage. The double rollers of the first wheel frame 405 and the second wheel frame 407 work together to enhance the conveying stability, effectively solve the problems of film deviation and roller detachment, and improve the synchronous bonding accuracy.

[0031] Please see Figures 1 to 5 As shown, a groove 207 is formed on the surface of the mounting housing 201. Sliding blocks 208 are fixed to the surfaces of both the first movable plate 203 and the C-shaped housing 205, and the sliding blocks 208 are slidably connected to the surface of the groove 207. In this embodiment, the groove 207 and the sliding blocks 208 cooperate to restrict the movement direction of the C-shaped housing 205 and the first movable plate 203, ensuring that the pressure roller 206 always acts perpendicularly to the surface of the winding wheel. The surface of the mounting housing 201 is provided with scale lines 209 that cooperate with the sliding blocks 208. The scale lines 209 mark the position of the sliding blocks 208, allowing the operator to adjust the initial pressure by rotating the lead screw 202 according to the scale values.

[0032] Please see Figures 1 to 5 As shown, multiple extension blocks 306 are fixed to the surface of the mounting plate 103, and the extension blocks 306 are slidably connected to the inner wall of the movable frame 302. The extension blocks 306 are embedded in the inner wall of the movable frame 302, restricting the movable frame 302 to move only in the vertical direction, thus enhancing the stability of the movable frame 302's movement. A rubber buffer pad 406 is fixed to the surface of the second wheel frame 407, and the surface of the rubber buffer pad 406 is fixedly connected to the inner wall of the mounting frame 401. The rubber buffer pad 406 connects the second wheel frame 407 and the mounting frame 401, absorbing the impact force during film conveying and reducing the impact of mechanical vibration on the film surface quality.

[0033] In this embodiment, upon startup, the easy-tear tape reel 104 and the film reel 105 release the easy-tear tape and film respectively. The auxiliary mechanism 2 applies adaptive pressure to the reel via the pressure roller 206, and the compression spring 204 maintains constant pressure through its own elasticity. In the tension adjustment mechanism 3, the first electric push rod 301 drives the rotating roller 304 to move, and the tension sensor 303 provides real-time feedback data to dynamically adjust the stretch of the easy-tear tape. The film conveying mechanism 4 adjusts the pressing force of the conveying roller 408 via the second electric push rod 402, and the pressure sensor 404 ensures smooth film conveying. Finally, the easy-tear tape and film are synchronously bonded and output via the output roller 106, completing the feeding process.

[0034] Although specific embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these specific embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
