Description

Technical Field

[0001] The utility model relates to the technical field of tape production, in particular to a sizing device for Teflon tape. Background Art

[0002] Teflon tape, also known as PTFE tape, or Teflon adhesive tape, or PTFE adhesive tape, is a high-temperature resistant tape made by first using glass fiber as the base fabric, coating it with PTFE emulsion and drying it to make PTFE fiberglass cloth, and then coating it with silicone adhesive for the second time. The characteristics of Teflon tape are high strength, high temperature resistance, normal temperature resistance up to 260 degrees, smooth surface, anti-sticking, bright, and resistant to various chemical corrosions.

[0003] When the Teflon tape is coated and wound, due to insufficient tension in the tape transmission, wrinkles will occur, resulting in unevenness of the wound tape, affecting the quality of the tape. Moreover, after the tape is sized, the flatness of the adhesive surface is insufficient, and a smoothing process needs to be added to evenly apply the glue, which lengthens the production line and increases the defective rate of Teflon tape production.

[0004] Therefore, we propose a sizing device for Teflon tape to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a sizing device for Teflon tape to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A sizing device for Teflon tape includes two vertical plates. Between the two vertical plates, two rotating rollers are rotatably connected. The two rotating rollers are connected by a mesh belt. On the left and right sides of the mesh belt, a driven roller and a driving roller are respectively arranged. The driving roller is connected to one of the rotating rollers through a transmission mechanism. On the side wall of one of the vertical plates, a motor is fixedly connected. The driving shaft of the motor rotates through the vertical plate and is fixedly connected to the rotating roller coaxially. On the opposite sides of the two vertical plates, two leveling rollers are arranged. The vertical plate is provided with a buffer mechanism for buffering the leveling rollers.

[0008] Further, the transmission mechanism includes a first belt pulley and a second belt pulley. The first belt pulley is fixedly connected to the rotating roller coaxially. The second belt pulley is fixedly connected to the driving roller coaxially. The first belt pulley and the second belt pulley are connected by a synchronous belt.

[0009] Further, the buffer mechanism includes a groove provided on the vertical plate. A slider is slidably connected in the groove. A buffer spring is fixedly connected between the upper end of the slider and the inner top of the groove. One end of the slider away from the inner bottom of the groove is fixedly connected with a rotating shaft, and the rotating shaft is coaxially and fixedly connected with the flattening roller.

[0010] Further, the included angle between the axis of the rotating shaft and the connecting plane of the slider is 30-45°.

[0011] Further, the outer wall of the driven roller is smooth, and the outer wall of the driving roller is frosted.

[0012] Further, a plurality of square holes are provided on the mesh belt, and the plurality of square holes are evenly distributed in an array.

[0013] Further, the two flattening rollers associated with the same vertical plate are arranged in translational symmetry, and the flattening rollers associated with two vertical plates are arranged in axial symmetry.

[0014] Compared with the prior art, the beneficial effects of the present utility model are at least as follows:

[0015] By providing the mesh belt and the flattening roller, the rotating roller is driven to rotate by the motor, the rotating roller drives the mesh belt and the driving roller to rotate. The tape passing through the driving roller moves to the right under the pulling force of the subsequent process winding. The driving roller and the rotating roller rotate counterclockwise at the same time. During the rotation process, the driving roller can share part of the pulling force on the tape, reduce the tension on the subsequent tape, and avoid the situation that the tape is deformed due to excessive tension. The rotating roller drives the mesh belt to rotate counterclockwise, so that the moving direction of the upper mesh belt is opposite to the tape conveying direction. Thus, the excess glue on the tape can be scraped off through the square holes on the mesh belt. At the same time, the position with less glue application can be re-coated to achieve uniform glue application. Meanwhile, when the tape moves, it will drive the flattening roller to rotate. Since the flattening roller is inclined, when the flattening roller rotates, it will apply a tension force to both sides of the tape, thereby flattening the tape, improving the quality of tape production. Moreover, the flattening roller and the mesh belt are arranged at the same position, without the need to add additional processes, shortening the production line and improving the yield of tape production.

[0016] The present utility model can flatten the tape and evenly apply the glue, shorten the production line, and improve the yield of tape production. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present utility model will be described in detail below in conjunction with the specific embodiments shown in the drawings. However, these embodiments do not limit the present utility model, and any structural, methodical, or functional transformations made by those of ordinary skill in the art based on these embodiments are included within the protection scope of the present utility model.

[0024] Please refer to Figures 1 to 5 , a Teflon tape gluing device, including two vertical plates 1, two rotating rollers 2 are rotatably connected between the two vertical plates 1, and the two rotating rollers 2 are drivingly connected through a mesh belt 3. Specifically, a plurality of square holes 16 are provided on the mesh belt 3, and the plurality of square holes 16 are evenly arranged in an array. It should be noted that the square holes 16 can scrape off the excess glue on the tape, and a part of the scraped glue will adhere to the mesh belt 3. When the glue is not applied locally on the tape, the tape can be re-coated. A driven roller 4 and a driving roller 5 are respectively arranged on the left and right sides of the mesh belt 3. It should be noted that the outer wall of the driven roller 4 is smooth, and the outer wall of the driving roller 5 is frosted. It should be noted that the frosted setting can increase the friction with the tape, thereby reducing the tension on the tape in the subsequent process. The driving roller 5 is drivingly connected to one of the rotating rollers 2 through a transmission mechanism 6. It should be noted that the transmission mechanism 6 includes a first pulley 10 and a second pulley 11, and the first pulley 10 is coaxially and fixedly connected to the rotating roller 2.

[0025] In this embodiment, the second pulley 11 is fixedly connected to the driving roller 5 coaxially. The first pulley 10 and the second pulley 11 are connected by a synchronous belt. A motor 7 is fixedly connected to the side wall of one of the vertical plates 1. The driving shaft of the motor 7 rotates through the vertical plate 1 and is fixedly connected to the rotating roller 2 coaxially. Two leveling rollers 8 are provided on each of the opposite sides of the two vertical plates 1. A buffer mechanism 9 for buffering the leveling rollers 8 is provided on the vertical plate 1. It should be noted that the buffer mechanism 9 includes a groove 12 provided on the vertical plate 1. A slider 14 is slidably connected in the groove 12. The upper end of the slider 14 is fixedly connected to the inner top of the groove 12 by a buffer spring 13. One end of the slider 14 away from the inner bottom of the groove 12 is fixedly connected to a rotating shaft 15. It is worth mentioning that the included angle between the axis of the rotating shaft 15 and the connecting plane of the slider 14 is 30-45°. It should be noted that when the leveling roller 8 rotates, it will apply a tension force to both sides of the tape, thereby leveling the tape. The rotating shaft 15 is fixedly connected to the leveling roller 8 coaxially. It should be noted that the two leveling rollers 8 associated with the same vertical plate 1 are arranged in translational symmetry, and the leveling rollers 8 associated with the two vertical plates 1 are arranged in axial symmetry. Refer to Figure 2 , the straight dotted line is the tape conveying trajectory, the arc dotted line is the rotation direction of the driving roller 5 and the rotating roller 2, and the side of the tape with glue attached faces downward.

[0026] In this embodiment, the motor 7 drives the rotating roller 2 to rotate. The rotating roller 2 drives the mesh belt 3 and the driving roller 5 to rotate. The tape passing through the driving roller 2 moves to the right under the pulling force of the subsequent winding process. The driving roller 5 and the rotating roller 2 rotate counterclockwise at the same time. During the rotation process, the driving roller 5 can share a part of the pulling force on the tape, reducing the tension on the subsequent tape. The rotating roller 2 drives the mesh belt 3 to rotate counterclockwise, so that the moving direction of the upper mesh belt 3 is opposite to the tape conveying direction. Then, the excess glue on the tape can be scraped off through the square holes 16 on the mesh belt. At the same time, the positions with less glue application can be coated again to achieve uniform glue application. At the same time, when the tape moves, it will drive the leveling roller 5 to rotate. Since the leveling roller 5 is inclined, when the leveling roller 5 rotates, it will apply a tension force to both sides of the tape, thereby leveling the tape.
