Description

Technical Field

[0001] This utility model relates to the field of cigarette production technology, and in particular to a tipping paper unwinding adjustment device. Background Technology

[0002] In the tobacco industry, tipping paper is an important material used in cigarette filter parts. Its function is to connect the filter to the cigarette while ensuring the cigarette's airtightness and appearance. Tipping paper is usually supplied in roll form, which is unrolled by an unwinding device during production and then conveyed to subsequent processing equipment.

[0003] The unwinding device is a key component of the cigarette production line. Its main function is to support the tipping paper roll and release the tipping paper with stable tension during production to ensure the smooth progress of subsequent processes (such as cutting and pasting). However, since the process progress of the cigarette production line may fluctuate, the unwinding speed of the tipping paper needs to be adjusted in real time to avoid problems such as excessive tension causing the tipping paper to break, or insufficient tension causing loose rolling and wrinkles.

[0004] Currently, most traditional unwinding devices employ fixed speeds or simple mechanical tension control methods, which are ill-suited to dynamically changing process requirements. For example, some devices rely solely on friction braking or spring-based tension adjustment, resulting in slow response times and an inability to accurately match real-time changes in the production line. This can easily lead to waste of tipping paper or negatively impact product quality. Furthermore, the lack of efficient tension detection and feedback mechanisms in existing technologies results in insufficient adjustment precision in unwinding devices, making it difficult to meet the requirements of high-speed, high-stability production.

[0005] Therefore, there is an urgent need for a device that can adjust the unwinding speed in real time based on the pressure of the tipping paper, in order to improve production efficiency, reduce material waste, and ensure the quality stability of cigarette products. Utility Model Content

[0006] The purpose of this invention is to provide a tipping paper unwinding adjustment device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A tipping paper unwinding adjustment device includes: a back plate, an upper roller mounting plate disposed on the upper front side of the back plate, a roller disposed on the upper roller mounting plate, a vertically mounted first guide rail disposed on the front side of the back plate, a lower roller mounting plate mounted on the slider of the first guide rail, a roller disposed on the lower roller mounting plate, a displacement sensor disposed on one side of the back plate, the contact of the displacement sensor being connected to the lower roller mounting plate, and the contact being driven to move when the lower roller mounting plate moves up and down.

[0009] As a further embodiment of the present invention, the upper roller mounting plate is provided with a plurality of rollers, and the plurality of rollers are evenly spaced along the horizontal direction.

[0010] The lower roller mounting plate is provided with multiple rollers, which are evenly spaced along the horizontal direction.

[0011] As a further embodiment of this utility model, there are multiple first guide rails, and the multiple first guide rails are arranged in parallel.

[0012] As a further embodiment of this utility model, it also includes a counterweight assembly, which includes a counterweight block, a pulley and a rope. The pulley is installed above the first guide rail on the front side of the back plate. One end of the rope is connected to the counterweight block, and the other end of the rope passes around the pulley and is connected to the lower roller mounting plate.

[0013] As a further embodiment of the present invention, the counterweight assembly further includes a second guide rail, which is vertically mounted on the front side of the back plate, and the counterweight is mounted on the slider of the second guide rail.

[0014] As a further embodiment of this utility model, there are two pulleys, which are arranged horizontally. One pulley is installed directly above the lower roller mounting plate and higher than the first guide rail, and the other pulley is installed on one side of the top of the second guide rail.

[0015] As a further embodiment of this utility model, a clearance opening is provided on one side of the lower roller mounting plate, the clearance opening being used to avoid interference when the lower roller mounting plate intersects with the counterweight.

[0016] As a further embodiment of the present invention, the counterweight assembly further includes an additional counterweight block, wherein there are one or more additional counterweight blocks, and one or more of the additional counterweight blocks are fixed on the counterweight block.

[0017] As a further embodiment of this utility model, it also includes a paddle, one side of which is fixed to the side of the lower roller mounting plate near the displacement sensor, and the other side of which is provided with a U-shaped notch, into which the contact is inserted.

[0018] As a further embodiment of the present invention, it also includes a housing, which is disposed on one side of the back plate and covers components other than the roller. The housing is provided with a window for the movement of the roller.

[0019] The advantages of this invention are: the position of the lower roller reflects the tension of the tipping paper, and the positional variable is converted into an electrical signal by a displacement sensor to control the unwinding speed of the preceding process or adjust the feed speed of the subsequent process. Furthermore, to ensure the lower roller mounting plate responds sensitively to the tipping paper, a counterweight assembly is added in this application. This counterweight assembly offsets most of the weight of the lower roller mounting plate and the roller, allowing even minor tension fluctuations on the tipping paper to move the lower roller mounting plate.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figure 2 , Figure 3As shown, a tipping paper unwinding adjustment device includes: a back plate 1, an upper roller mounting plate 2 disposed above the front side of the back plate 1, a roller 4 disposed on the upper roller mounting plate 2, preferably multiple rollers 4 disposed on the upper roller mounting plate 2, the multiple rollers 4 being evenly spaced along the horizontal direction, a vertically mounted first guide rail 5 disposed on the front side of the back plate 1, a lower roller mounting plate 3 disposed on the slider of the first guide rail 5, and rollers 4 disposed on the lower roller mounting plate 3, preferably multiple rollers 4 disposed on the lower roller mounting plate 3, the multiple rollers 4 being evenly spaced along the horizontal direction. To ensure the stability of the lower roller mounting plate 3 during vertical movement, preferably, there are multiple first guide rails 5, the multiple first guide rails 5 being arranged in parallel. A displacement sensor 7 is disposed on one side of the back plate 1, the contact 71 of the displacement sensor 7 being connected to the lower roller mounting plate 3, driving the contact 71 to move accordingly when the lower roller mounting plate 3 moves vertically.

[0031] In one specific embodiment, the preceding process of the tipping paper unwinding adjustment device of this application includes an unwinding device, and the following process includes a tipping paper cutting device. In the initial state, the tipping paper is installed on the roller of the preceding unwinding device. The rotation of the roller drives the tipping paper to be released. After the tipping paper enters the unwinding adjustment device, it first passes around the first roller on the left side of the upper roller, then passes down around the first roller on the left side of the lower roller, then passes up around the second roller on the upper roller again, and so on, alternately passing up and down to enter the following process.

[0032] When the unwinding speed is less than the cutting speed, the pressure on the cork paper increases, causing the lower roller mounting plate to move upwards. This upward movement of the mounting plate moves the contacts of the displacement sensor, converting the position signal into an electrical signal. During this process, the change in tension causes a change in the lower roller displacement, which is then converted into a voltage change. The voltage signal from the displacement sensor can be fed back to the front-end unwinding driver to reduce the unwinding speed, and simultaneously fed back to the rear-end cutting equipment to increase the cutting speed.

[0033] When the weight of the lower roller mounting plate 3 and the roller 4 mounted on it is large, it is difficult to drive the lower roller mounting plate 3 up and down solely by the tension of the tipping paper, and the displacement of the lower roller mounting plate 3 is not sensitive enough to the tension. To solve this problem, this application also includes a counterweight assembly, which includes a counterweight block 10, a pulley 8, and a rope 9. The pulley 8 is mounted above the first guide rail 5 on the front side of the back plate 1. One end of the rope 9 is connected to the counterweight block 10, and the other end of the rope 9 passes around the pulley 8 and is connected to the lower roller mounting plate 3. To reduce interference and limit the swing of the counterweight block 10, the counterweight assembly also includes a second guide rail 6, which is vertically mounted on the front side of the back plate 1. The counterweight block 10 is mounted on the slider of the second guide rail 6. In a preferred embodiment, there are two pulleys 8, which are arranged horizontally. One pulley 8 is mounted directly above the lower roller mounting plate 3 and above the first guide rail 5, and the other pulley 8 is mounted on one side of the top of the second guide rail 6.

[0034] In one specific embodiment, the counterweight and water-tightening force of the paper is equal to the weight of the lower roller mounting plate and its roller, and the system remains balanced. When the tension decreases, the lower roller mounting plate moves downward; when the tension increases, the lower roller mounting plate moves upward. The displacement signal is converted into an electrical signal to drive the preceding or subsequent processes to make corresponding adjustments, allowing the system to enter a stable state again.

[0035] To reduce the width of this device, when the counterweight 10 and the lower roller mounting plate 3 move up and down, a clearance opening 31 is provided on one side of the lower roller mounting plate 3, such as... Figure 7 As shown, the clearance 31 is used to avoid interference when the lower roller mounting plate 3 and the counterweight block 10 intersect.

[0036] In a preferred embodiment of this utility model, the counterweight assembly further includes an additional counterweight block 11, such as... Figure 6 As shown, there are one or more additional counterweights 11, and one or more of the additional counterweights 11 are fixed to the counterweight 10. The advantage of doing so is that it is convenient to adjust the counterweight to adapt to different lower roller mounting plates. For example, when the number of rollers on the lower roller mounting plate increases, its overall weight also increases, requiring the counterweight to be adjusted accordingly.

[0037] To facilitate the replacement of the displacement sensor, the contact of the displacement sensor is detachably connected to the lower roller mounting plate, specifically using a lever 13 for connection. Figure 5 As shown, one side of the lever 13 is fixed to the side of the lower roller mounting plate 3 near the displacement sensor 7, and the other side of the lever 13 is provided with a U-shaped notch 131, into which the contact 71 is inserted.

[0038] In a preferred embodiment of this utility model, a shell 12 is also included, such as... Figure 1 As shown, the outer casing 12 covers one side of the back plate 1, concealing all components except the roller 4. The outer casing 12 has a window 121 for the movement of the roller 4. The main function of the outer casing is to prevent dust and to avoid lubricant contamination of the cork paper.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
