Description

Technical Field

[0001] This utility model relates to the field of self-adhesive label winding technology, specifically, to a self-adhesive label winding tension control device. Background Technology

[0002] Self-adhesive labels offer advantages over traditional labels, including no need for glue, paste, or water, zero pollution, and time-saving application. They are widely applicable and convenient. Self-adhesive labels, also known as self-adhesive label materials, are composite materials made of paper, film, or other special materials as the face stock, coated with adhesive on the back, and with silicone-coated release paper as the backing. After printing, die-cutting, and other processing, they become finished labels. Maintaining constant tension during the rolling process is crucial to ensuring production efficiency and the surface quality of the roll material. This plays a vital role in product quality.

[0003] In the existing technology, the driving element of the tension control device for roll material usually uses the extension and retraction of the cylinder. However, this tension control method can cause the tension adjustment effect to lag due to the cylinder extending or retracting too quickly or not in time, which is insufficient for maintaining the constant tension of the self-adhesive label during the winding stage. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a self-adhesive retractable film tension control device, which has the advantage of precise tension control, thereby solving the problems mentioned in the background technology.

[0007] To achieve the aforementioned advantages of precise tension control, the specific technical solution adopted by this utility model is as follows: A self-adhesive label winding tension control device includes a winding roller, a tension adjustment unit, a tension sensor, a transmission roller, and several guide rollers. The surface of the winding roller is wound with a self-adhesive label tape, and a transmission roller is located at the end of the self-adhesive label tape away from the winding roller. Several guide rollers are arranged between the winding roller and the transmission roller. A tension adjustment unit and a tension sensor are sequentially arranged between the guide rollers from left to right. A groove is formed on the inner wall of the tension adjustment unit, and a slider is slidably installed within the groove. A moving part is fixed to one end of the slider, and an adjustment roller is mounted on the surface of the moving part via a bearing seat. A rack is arranged parallel to the groove at the upper end of the moving part. A servo motor is fixedly installed on one side of the tension adjustment unit, and a gear meshing with the rack is fixed to the output end of the servo motor. A PLC controller is fixed to the other side of the tension adjustment unit, and the output end of the PLC controller is electrically connected to the servo motor. The tension sensor is electrically connected to the PLC controller.

[0008] Furthermore, the tension adjustment unit has through ports on both the left and right sides, and the top surface of the tension adjustment unit has a clearance port corresponding to the rack.

[0009] Furthermore, the shafts of the adjusting roller and the tension sensor are in contact with the bottom surface of the non-adhesive label tape, and the guide roller is in contact with the top surface of the non-adhesive label tape.

[0010] Furthermore, the tension sensor is model MB25, and a differential transformer is built into the tension sensor.

[0011] Furthermore, the movable component is disposed close to the inner wall of the tension adjustment unit, and the surface of the movable component has several mounting holes corresponding to the adjustment roller.

[0012] Furthermore, the length of the adjusting roller is less than the width inside the tension adjusting unit, and the width inside the passage is matched with the length of the adjusting roller.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a self-adhesive retractable film winding tension control device, which has the following beneficial effects:

[0015] This invention employs a winding tension control device consisting of a winding roller, a tension adjustment unit, a tension sensor, a transmission roller, and a PLC controller. The tension sensor directly measures the real-time tension of the roll material and outputs a voltage or current signal proportional to the tension. When the detected voltage or current signal exceeds the preset range of the PLC controller, the PLC controller activates the servo motor of the tension adjustment unit to rotate forward or backward. This causes the gear at the output end of the servo motor to drive the meshing rack to move up and down. The moving part then slides up and down inside the groove via a slider, allowing the adjustment roller mounted on the moving part to pull the self-adhesive label tape, thus controlling and maintaining a constant tension. Compared to the existing method of tension control using a cylinder, the gear and rack meshing transmission method increases the accuracy of tension control during the self-adhesive label winding stage.

[0024] According to an embodiment of the present invention, a self-adhesive rewinding tension control device is provided.

[0025] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, a self-adhesive label winding tension control device according to an embodiment of the present invention includes a winding roller 1, a tension adjustment unit 2, a tension sensor 3, a transmission roller 4, and several guide rollers 6. The surface of the winding roller 1 is wound with a self-adhesive label tape, and the end of the self-adhesive label tape away from the winding roller 1 is provided with the transmission roller 4. Several guide rollers 6 are arranged between the winding roller 1 and the transmission roller 4. The tension adjustment unit 2 and the tension sensor 3 are arranged sequentially from left to right among the several guide rollers 6. A groove 7 is formed on the inner wall of the tension adjustment unit 2, and a slider 13 is slidably installed in the groove 7. A movable part 8 is fixed to one end of the slider 13, and an adjustment roller 9 is mounted on the surface of the movable part 8 through a bearing seat. Furthermore, a rack 11 is arranged parallel to the slide groove 7 at the upper end of the moving part 8. A servo motor 14 is fixedly installed on one side surface of the tension adjustment unit 2, and a gear 12 that meshes with the rack 11 is fixed at the output end of the servo motor 14. A PLC controller 5 is fixed on the other side surface of the tension adjustment unit 2, and the output end of the PLC controller 5 is electrically connected to the servo motor 14. The tension sensor 3 is electrically connected to the PLC controller 5. The control circuit of the PLC controller 5 can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. It is only used and not modified. Therefore, the control method and circuit connection will not be described in detail.

[0026] In one embodiment, the tension adjustment unit 2 has passage openings 10 on both the left and right sides, and the top surface of the tension adjustment unit 2 has a clearance opening corresponding to the rack 11. This structure facilitates the passage of non-adhesive label tape.

[0027] In one embodiment, the shafts of the adjusting roller 9 and the tension sensor 3 are in contact with the bottom surface of the non-adhesive label tape, and the guide roller 6 is in contact with the top surface of the non-adhesive label tape. With this structure, the shafts of the adjusting roller 9 and the tension sensor 3 apply an upward force to the non-adhesive label tape, and the guide roller 6 applies a downward force to the non-adhesive label tape.

[0028] In one embodiment, the tension sensor 3 is model MB25, and the tension sensor 3 has a built-in differential transformer. This structure makes it easy to perform online tension detection on the winding of self-adhesive label tape.

[0031] Working principle: First, the self-adhesive label tape is conveyed by the transmission roller, and then the self-adhesive label tape is wound up by the transmission roller 4. During this process, the tension sensor 3 set between several guide rollers 6 directly measures the real-time tension of the roll material and outputs a voltage or current signal proportional to the tension. When the detected voltage or current signal exceeds the preset value range of the PLC controller 5, the PLC controller 5 starts the servo motor 14 of the tension adjustment unit 2 to rotate forward or backward, causing the gear 12 at the output end of the servo motor 14 to drive the rack 11 meshing with it to move up and down. Then, the moving part 8 slides up and down inside the slide groove 7 through the slider 13, so that the adjustment roller 9 installed on the moving part 8 pulls the self-adhesive label tape to achieve tension control and maintain constant tension.
