Description

Technical Field

[0001] This utility model belongs to the field of cigarette production technology, specifically a device for correcting the deviation of forming paper. Background Technology

[0002] Cigarette production is an industrial system centered on tobacco processing, covering the entire process from tobacco leaf planting to finished product delivery. Filter rods are an essential part of cigarettes, and in the production of filter rods, tipping paper, commonly known as forming roll paper, is required. This paper plays an important role in filter rod production, used to roll and wrap the already formed tobacco strands, commonly known as filter strips.

[0003] Chinese patent CN212310172U discloses a cigarette paper conveying track cleaning device and a cigarette paper conveying device. The former includes a mounting block, a scraper hook, a hook drive device, a suction device, and a controller. The mounting block is disposed on a pressure plate at the cigarette paper conveying track, near the glue nozzle. The mounting block has a guide groove on its side facing the cigarette paper conveying track for cooperating with the scraper hook, and a suction port located below the guide groove. The suction inlet of the suction device is connected to the suction port. The hook drive device drives the scraper hook to reciprocate within the guide groove. The scraper hook has a scraping part for contacting the cigarette paper conveying track. The hook drive device and the suction device are electrically connected to the controller. This invention can effectively clean the cigarette paper conveying track at the glue nozzle, avoiding frequent cigarette paper breakage and improving equipment production efficiency.

[0004] As mentioned above, this patent provides a cigarette paper conveying track cleaning device and a cigarette paper conveying device. The device can effectively clean the cigarette paper conveying track at the glue nozzle, avoid frequent cigarette paper breakage, and improve the production efficiency of the equipment. However, when conveying the tipping paper, the paper edge position is highly critical. Since the forming paper is very thin, if the tension of the forming paper is adjusted to keep it taut to prevent it from shifting during conveying, it may cause the forming paper to break. Therefore, the tension of the forming paper cannot be too tight, otherwise the forming paper will deviate during conveying. Deviating of the forming paper will affect subsequent forming processes and lead to the production of defective products.

[0005] Therefore, a paper straightening device is proposed to address the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies and solve the problem of adjusting the tension of the forming paper to ensure it remains taut and prevents it from shifting during transport, which could lead to breakage, the tension of the forming paper cannot be too tight. Excessive tension can cause the forming paper to deviate during transport, affecting subsequent forming processes and resulting in defective products. Therefore, a forming paper deviation correction device is proposed.

[0023] 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 scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] Please see Figures 1-4 This utility model provides a paper correction device, including a side plate 1, an infrared outer deviation assembly, and a correction assembly. A guide roller 2 is rotatably connected to one side of the side plate 1. The infrared outer deviation assembly includes an adjusting bracket 31, a light source generator 32, a support plate 33, and a light source receiver 34. The correction assembly includes a plate 52 fixedly connected to one side of the side plate 1. A movable groove 53 is formed inside the plate 52, and a slide block 54 is slidably connected inside the movable groove 53. A correction seat 55 is fixedly connected to the top of the slide block 54. The correction seat 55 has a groove 56 for accommodating the paper. A screw 57 is rotatably connected inside the plate 52, and the surface of the screw 57 is threadedly connected to the inside of the slide block 54. During operation, the paper is wound around the guide roller 2. When the paper is pulled by the traction mechanism and moves on the guide roller 2, the light source generator 32 and the light source receiver 34 operate, adjusting the position of the paper. The system detects whether the paper is misaligned. When the paper is misaligned, it may partially or completely block the light beam emitted by the light source generator 32. At this time, the light source receiver 34 generates a misalignment signal. The light source receiver 34 can also be connected to an alarm. When the light source receiver 34 generates a misalignment signal, it outputs an alarm signal to the alarm, causing the alarm to sound and attracting the attention of the staff. The staff manually rotates the adjusting plate 51 to drive the screw 57 to rotate. When the screw 57 rotates, it can drive the slide 54 to move in the movable groove 53, thereby driving the correction seat 55 to move. When the correction seat 55 moves, it can drive the paper that passes through the groove 56 to move, thereby adjusting the position of the misaligned paper and realizing the correction. When the paper moves and no longer blocks the light beam emitted by the light source generator 32, the light source receiver 34 stops outputting the misalignment signal, the alarm is canceled, and the manual correction adjustment of the paper is completed.

[0026] Furthermore, such as Figure 1 and Figure 4As shown, the adjustment bracket 31 is fixedly connected to one side of the side plate 1, the light source generator 32 is fixedly connected to one end of the adjustment bracket 31, the surface of one side of the side plate 1 is fixedly connected to the surface of the support plate 33, the light source receiving end 34 is fixedly connected to the top of the support plate 33 and is located on the same vertical axis as the light source generator 32; one end of the screw 57 passes through the plate 52 and extends outward, and the extended end of the screw 57 is fixedly connected to the adjustment plate 51. During operation, the side plate 1 supports the adjustment bracket 31, which in turn supports the light source generator 32. The light source generator 32 includes a light source and a lens. The light emitted by the light source is focused into a parallel beam by the lens. In addition, the side plate 1 also supports the support plate 33, which in turn supports the light source receiving end 34. The light source, which is focused into a parallel beam by the light source and lens in the light source generator 32, can shine on the light source receiving end 34. The light source receiving end 34 is a photoresistor that detects the intensity of the light. Part of the parallel beam is blocked by the strip being tested, which reduces the light flux transmitted to the photoresistor, thereby generating a detection signal. This sensor can accurately detect whether the strip has deviated from the correct position and provide a correction signal in a timely manner.

[0027] Furthermore, such as Figure 2 and Figure 3 As shown, multiple guide rollers 2 are provided, and one of the guide rollers 2 has a negative pressure suction port 62 inside. An air pipe interface 2 6 is fixed to one side of the side plate 1, and the air pipe interface 2 6 is connected to the negative pressure suction port 62. During operation, multiple guide rollers 2 are provided to guide the forming paper. At the same time, one of them has a negative pressure suction port 62, and the air pipe interface 2 6 can be connected to a vacuum pump through a pipe. The operation of the vacuum pump can generate negative pressure in the negative pressure suction port 62, thereby generating suction force in the negative pressure suction port 62 to attract the forming paper passing over the outer surface of the guide roller 2, which can limit the forming paper and prevent the forming paper from deviating.

[0028] Furthermore, such as Figures 1-3As shown, a paper dust removal assembly is provided on one side of the side plate 1. The paper dust removal assembly includes a brush 41 rotatably connected to one side of the side plate 1. A motor 42 is fixedly connected to the side of the side plate 1 away from the guide roller 2. The output shaft of the motor 42 passes through the side plate 1 and extends to one side of the guide roller 2. One end of the output shaft of the motor 42 located on the side of the guide roller 2 is fixedly connected to one end of the brush 41. An air jet 43 is fixedly connected to one side of the side plate 1. An air pipe interface 44 connected to the air jet 43 is fixedly connected to the side of the side plate 1 away from the air jet 43. During operation, the air pipe interface 44 is connected to the air compressor through a pipe. Since there may be paper dust on the surface of the forming paper, in order to prevent the paper dust from entering the negative pressure suction port 62 and causing blockage, the motor 42 drives the brush 41 to rotate. The brush 41 is a soft brush. The brush 41 removes the paper dust on one side of the forming paper. At the same time, the jet 43 blows air into the contact area between the brush 41 and the forming paper. The air blowing combined with the rotation of the brush 41 can thoroughly remove the paper dust and improve the adaptability of use.

[0029] First, the forming paper is wound around the guide roller 2. When the forming paper is pulled by the traction mechanism and moves on the guide roller 2, the light source generator 32 and the light source receiver 34 work to detect whether the position of the forming paper is off. When the position of the forming paper is off, it will partially or completely block the light beam emitted by the light source generator 32. At this time, the light source receiver 34 generates an offset signal. The light source receiver 34 can also be connected to an alarm. When the light source receiver 34 generates an offset signal, it outputs an alarm signal to the alarm, causing the alarm to sound and attracting the attention of the staff. The staff manually rotates the adjusting plate 51 to drive the screw 57 to rotate. When the screw 57 rotates, it can drive the slide 54 to move in the movable groove 53, thereby driving the correction seat 55 to move. When the correction seat 55 moves, it can drive the forming paper passing through the groove 56 to move, thereby adjusting the position of the off-center forming paper and realizing the correction. When the moving forming paper no longer blocks the light beam emitted by the light source generator 32, the light source receiver 34 stops outputting the offset signal, the alarm is canceled, and the manual correction adjustment of the forming paper is completed. In addition, the side plate 1 supports the adjustment bracket 31 and uses the adjustment bracket 31 to support the light source generator 32. The light source generator 32 includes a light source and a lens. The light emitted by the light source is focused into a parallel beam by the lens. The side plate 1 also supports the support plate 33 and uses the support plate 33 to support the light source receiver 34. The light source, which is focused into a parallel beam by the light source and lens in the light source generator 32, can shine on the light source receiver 34. The light source receiver 34 is a photoresistor that detects the intensity of the light. Part of the parallel beam is blocked by the strip being tested, which reduces the light flux transmitted to the photoresistor, thereby generating a detection signal. This sensor can accurately detect whether the strip is deviating from the correct position and provide a correction signal in a timely manner. Meanwhile, multiple guide rollers 2 are set to guide the forming paper. One of them has a negative pressure suction port 62, and the air pipe interface 2 6 can be connected to a vacuum pump through a pipe. When the vacuum pump works, it can generate negative pressure in the negative pressure suction port 62, thereby generating suction in the negative pressure suction port 62 to attract the forming paper passing through the outer surface of the guide roller 2. This can limit the forming paper and prevent it from deviating.Finally, the air pipe interface 44 is connected to the air compressor via a pipe. Since paper dust may be present on the surface of the formed paper, to prevent paper dust from entering the negative pressure suction port 62 and causing blockage, the motor 42 drives the brush 41 to rotate. The brush 41 is a soft brush, which removes paper dust from one side of the formed paper. Simultaneously, the jet nozzle 43 blows air into the contact area between the brush 41 and the formed paper. This air blowing, combined with the rotation of the brush 41, thoroughly removes the paper dust, improving its adaptability. The entire system is equipped with an infrared outer polarization component, and the light emitted by the light source generator 32 is focused onto the light source receiver 34. If the light beam is partially blocked by the forming paper being tested, the light flux transmitted to the photoresistor will be reduced, thereby generating a detection signal. This can accurately detect whether the forming paper has deviated from the correct position and provide a timely correction signal. When the strip is detected to be off-position, the correction component is controlled to move the forming paper, realizing automated deviation detection and correction of the strip. At the same time, a paper dust removal component is set up. The motor 42 drives the brush 41 to rotate. The brush 41 brushes away the paper dust on one side of the forming paper. At the same time, the jet 43 blows air into the contact area between the brush 41 and the forming paper. The air blowing, combined with the rotation of the brush 41, can completely remove the paper dust, improving the adaptability of use.
