Abstract

The application discloses a constant tension adjusting device for tipping paper and relates to the technical field of tension adjusting. The device comprises a mounting frame, a driving unit and a tension unit. The driving unit comprises a plurality of staggered steering rollers and driving rollers, which are mounted on the mounting frame. The tension unit comprises a moving plate and a tension compensation roller. The moving plate is arranged on the mounting frame and can move relative to the mounting frame.

Description

Technical Field

[0001] This application relates to the technical field of tension adjustment, and in particular to a constant tension adjustment device for cork paper. Background Technology

[0002] Currently, the tension of the tipping paper feeding system on cigarette machines is inconsistent during the start-up phase. This inconsistency causes errors during positioning and cutting, leading to misaligned patterns. This situation poses a quality hazard; if defective products generated during the inconsistent tension phase are not completely removed, quality incidents can occur. To avoid such incidents, the rejection rate during start-up must be increased to a safe level, which also increases the scrap rate, resulting in wasted capacity and reduced production efficiency. Therefore, a device for constant tension regulation and balance of the tipping paper is needed. Through a set control method, constant tension of the tipping paper can be achieved, reducing the product scrap rate. Current tipping paper tension regulation devices suffer from significant tension fluctuations, leading to inaccurate cutting. Summary of the Invention

[0003] The purpose of this application is to provide a constant tension adjustment device for cork paper to solve the problem that the constant tension adjustment device has large fluctuations in tension, which leads to inaccurate cutting.

[0004] The water-pressed paper constant tension adjustment device provided in this application adopts the following technical solution:

[0005] A constant tension regulating device for cork paper, comprising:

[0006] Mounting rack;

[0007] The drive unit includes a drive roller mounted on a mounting frame for rotating and conveying the tipping paper;

[0008] The tension unit includes a tension compensation roller, which is mounted on a mounting frame and can move relative to the mounting frame to pull the tipping paper.

[0009] There are two drive rollers, and a tension compensation roller is located between the two drive rollers.

[0010] By adopting the above technical solution, the drive roller can rotate and transport the tipping paper, and keep the tipping paper in a constant tension state by stretching the tipping paper. When the tension changes due to the tension difference of the tipping paper itself or due to the change of the speed of the drive roller, the tension compensation roller can move to pull the tipping paper, thereby reducing the fluctuation of the tension of the tipping paper.

[0011] Optionally, a tension detection unit may also be included, which is located on the outside of the mounting bracket and includes a tension sensor.

[0012] By adopting the above technical solution, the tension sensor is used to sense the tension relief effect of the tipping paper. If there is an unqualified tension, the drive unit and tension unit can be adjusted in time to ensure the tension stability of the tipping paper.

[0013] Optionally, the mounting bracket is equipped with multiple steering rollers.

[0014] By adopting the above technical solution, multiple steering rollers can change the conveying direction of the tipping paper, which facilitates the tension balancing treatment of the tipping paper.

[0015] Optionally, the drive unit also includes a pressing roller and a swinging device. The swinging device is mounted on the mounting frame, and the pressing roller is connected to the swinging device and can press against the drive roller under the drive of the swinging device.

[0016] By adopting the above technical solution, the pressing roller can ensure that the tipping paper adheres to the surface of the drive roller. After the tipping paper is installed, it can be pressed on the drive roller, so that the tipping paper can be quickly tightened under the drive of the drive roller. The swinging device can separate the tipping paper from the drive roller before feeding, so that the tipping paper can be more easily wound on the drive roller, further improving the adaptability and ease of operation of the equipment.

[0017] Optionally, the swing device includes a swing arm and a swing cylinder, with the swing arm connected to the pressing roller and the swing cylinder connected to the drive swing arm.

[0018] By adopting the above technical solution, the swing cylinder can drive the swing arm to rotate, thereby driving the swing arm to drive the pressing roller, which stably clamps the tipping paper between the pressing roller and the drive roller, preventing slippage between the drive roller and the tipping paper, which would cause a sudden change in the tension of the tipping paper, thus improving the flatness and tension stability of the tipping paper.

[0019] Optionally, the drive unit also includes a drive device, which is mounted on the mounting base and connected to the drive roller.

[0020] By adopting the above technical solution, stable power transmission ensures more uniform stress during the pre-stretching process, reducing paper breakage caused by unstable power. The drive unit can adjust acceleration and deceleration accordingly based on the signal transmitted by the tension sensor, thereby better regulating the tension of the tipping paper and improving the reliability and production efficiency of the entire system.

[0021] Optionally, the mounting frame is provided with a movable groove, and a slide rail is provided in the movable groove. The tension compensation roller is connected to a movable plate, and the movable plate moves on the slide rail.

[0022] By adopting the above technical solution, the moving groove and slide rail enable the moving plate to move stably along a predetermined trajectory, thereby adjusting the position of the tension compensation roller according to the conveying speed of the tipping paper, thus playing a tension compensation role and ensuring that the magnitude of tension fluctuations is reduced.

[0023] Optionally, a buffer is provided at the edge of the moving slot to cushion the moving plate.

[0024] By adopting the above technical solution, the buffer can prevent the moving plate from colliding with the edge of the moving groove at a high speed, thereby ensuring the stable movement of the tension compensation roller, preventing excessive tension changes in the tipping paper, and ensuring the stability of tipping paper processing.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The combined action of multiple steering rollers and tension compensation rollers on the drive unit can reduce the tension of the tipping paper after passing through the drive unit and tension unit to an optimal level, ensuring that the tipping paper will not bend due to tension and cause inaccurate cutting during subsequent processing.

[0027] 2. The pressing roller ensures that the tipping paper adheres to the surface of the drive roller. After the tipping paper is installed, it can press the tipping paper on the drive roller, so that the tipping paper can be quickly tightened under the drive of the drive roller. The swinging device can separate the tipping paper from the drive roller before feeding, so that the tipping paper can be more easily wound on the drive roller, further improving the adaptability and ease of operation of the equipment.

[0028] 3. The swing cylinder can drive the swing arm to rotate, thereby driving the pressing roller to stably clamp the tipping paper between the pressing roller and the drive roller, preventing slippage between the drive roller and the tipping paper, which would cause a sudden change in the tension of the tipping paper, thus improving the flatness and tension stability of the tipping paper.

Detailed Implementation

[0033] The present application will be further described in detail below with reference to the accompanying drawings.

[0034] A constant tension regulating device for cork paper, as described above. Figure 1 It includes a mounting frame 1, a drive unit 2, a tension unit 3, and a tension detection unit 4. The drive unit 2 and the tension unit 3 are both mounted on the mounting frame 1. The drive unit 2 is used to transport and stretch the tipping paper, and the tension unit 3 is used to compensate for the tension based on the tension detected by the tension detection unit 4, thereby reducing the tension fluctuation on the tipping paper.

[0035] Reference Figure 1 The drive unit 2 includes two drive rollers 21, a drive device 26 connecting the drive rollers 21, a pressing roller 22, and a swing device 23 connecting the pressing roller 22. The drive rollers 21 and pressing roller 22 are mounted on the front of the mounting frame 1, which also has four guide rollers 11. The drive device 26 and swing device 23 are mounted on the back of the mounting frame 1. The guide rollers 11 and drive rollers 21 are staggered, with the two outermost drive rollers 21 and the four innermost guide rollers 11. The pressing roller 22 is positioned corresponding to the drive rollers 21 and can press the tipping paper onto the drive rollers 21 when needed, ensuring that the drive rollers 21 can reliably drive the conveying of the tipping paper.

[0036] Reference Figure 1 and Figure 3 The tension unit 3 includes a moving plate 32 and a tension compensation roller 31. The tipping paper is mounted on the drive roller 21, the tension compensation roller 31, and the guide roller 11. The mounting frame 1 has a moving groove 12, inside which is a slide rail 13. The moving plate 32 moves on the slide rail 13, and the tension compensation roller 31 is mounted on the moving plate 32, allowing the tension compensation roller 31 to move relative to the mounting frame 1. The tension compensation roller 31 is located between the guide rollers 11. By moving the tension compensation roller 31, tension compensation can be performed promptly when the tension of the tipping paper changes. A buffer 14 is provided at the edge of the moving groove 12. The buffer 14 cushions the movement of the moving plate 32, preventing violent collisions at the edge of the moving groove 12 and reducing tension fluctuations in the tipping paper.

[0037] Reference Figure 2The drive device 26 is located on the back of the mounting frame 1 and passes through the mounting frame 1 to connect to the drive roller 21, thereby enabling the drive roller 21 to rotate stably and accurately. The swing device 23 includes a swing arm 25 and a swing cylinder 24. The swing arm 25 is connected to the back of the mounting frame 1 and is connected to the pressing roller 22. The swing cylinder 24 is also connected to the back of the mounting frame 1. By pushing the swing arm 25, the swing arm 25 drives the pressing roller 22 to move. By setting a movable pressing roller 22, the water-tight paper can be more easily put on or taken off the drive roller 21 during the loading and unloading process, making the adjustment device more convenient to use.

[0038] Reference Figure 1 After passing through the drive unit 2 and the guide roller 11, the tipping paper enters the tension detection unit 4. The tension detection unit 4 includes a tension sensor 41 and a paper puller 42. The tension sensor 41 is located on the paper puller 42 and can detect the degree of tension relief of the tipping paper. Through the sensing of the tension sensor 41, the drive unit 2 and the tension unit 3 can be adjusted in time to ensure that the tension of the tipping paper is consistent.

[0039] The implementation principle of this embodiment is as follows: Tipping paper is wound and installed on the steering roller 11, tension compensation roller 31, and drive roller 21. After installation, the swing device 23 is adjusted to press the pressure roller 22 against the drive roller 21, thereby clamping the tipping paper between the drive roller 21 and the pressure roller 22, ensuring stable constant tension adjustment of the tipping paper. The drive device 26 drives the drive roller 21 to rotate, tightening the tipping paper between the steering roller 11 and the tension compensation roller 31, and transporting the tipping paper. The tension sensor 41 can sense the tension on the tipping paper, thereby transmitting a signal to the drive device 26 to adjust the conveying speed of the tipping paper, thus adjusting the tightness of the tipping paper and adjusting its tension. The tension compensation roller 31 can compensate for tension changes by moving, ensuring stable tension on the tipping paper.

[0040] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
