Description

Technical Field

[0001] This patent belongs to the field of tobacco paper tape preparation technology, specifically relating to a tobacco paper tape thickness adjustment device. Background Technology

[0002] In the precision manufacturing system of the tobacco industry, the uniformity of the thickness of the cigarette paper strip directly determines the appearance quality, functional stability, and equipment compatibility of cigarettes. For example, fluctuations in the thickness of the tipping paper can lead to wrinkles in the filter tip forming or misregistration in printing, while uneven thickness of the inner lining paper may cause breakage of the aluminum foil composite layer, affecting the moisture-proof and shelf-life performance of the cigarette.

[0003] Currently, the industry mainly controls the thickness of paper tape through the heating process. Traditional technology usually uses a single heating roller or a heating device with a fixed contact area to heat the paper tape, and indirectly adjusts the thickness of the paper tape by controlling the heating temperature or the paper tape travel speed.

[0004] However, this type of technology has obvious drawbacks:

[0005] On the one hand, the curved structure and fixed contact mode of a single heating roller result in significant differences in the transverse heating gradient of the paper tape. There is a natural difference in the actual heating time between the edge and center areas, and the adjustment flexibility for heating time is insufficient, making it difficult to adapt to the differentiated heating process requirements of paper tapes of different materials and specifications. For paper tapes containing special coatings or functional fibers, the fixed contact area cannot be dynamically adjusted according to parameters such as material thermal shrinkage characteristics and thermal conductivity, easily leading to uneven heat setting or functional layer failure.

[0006] On the other hand, in traditional fixed winding methods, the contact angle and path between the paper tape and the heating device lack a dynamic adjustment mechanism. When precise thickness control is required, it can only rely on adjusting a single variable such as temperature or speed. This control mode is prone to thickness fluctuations in high-speed production scenarios or with complex fiber-oriented paper tapes, making it difficult to control accuracy and failing to meet the stringent requirements of high-end products for thickness uniformity and stability.

[0007] Therefore, given the stringent requirements of the tobacco industry for uniformity of paper tape thickness, production flexibility, and functional stability, there is an urgent need for a technical solution to achieve precise control of the thickness of tobacco paper tape, meeting the requirements in terms of material compatibility, process flexibility, and precision stability. Utility Model Content

[0008] The purpose of this patent is to provide a device for adjusting the thickness of cigarette paper strips, so as to achieve precise control over the thickness of cigarette paper strips.

[0009] To solve the above-mentioned technical problems, this patent adopts the following technical solution:

[0010] A cigarette paper tape thickness adjustment device includes a frame, a roller assembly, a drive mechanism, and a heating and temperature control system.

[0011] The roller assembly is connected to the frame.

[0012] The roller assembly includes a fixed roller and an adjustable roller.

[0013] The drive mechanism is arranged on the frame and can drive the adjustable roller to move in the direction of approaching or moving away from the fixed roller;

[0014] Both the fixed roller and the adjustable roller are connected to the heating and temperature control system. The cigarette paper strip is connected to the fixed roller and the adjustable roller in sequence, so that the cigarette paper strip undergoes the first heating treatment on the fixed roller and the second heating treatment on the adjustable roller.

[0015] When the drive mechanism drives the adjustable roller to move in a direction closer to the fixed roller, the running path length of the cigarette paper strip on the fixed roller and the adjustable roller is reduced;

[0016] When the drive mechanism drives the adjustable roller to move away from the fixed roller, the running path length of the cigarette paper strip on the fixed roller and the adjustable roller increases.

[0017] Furthermore, the fixed roller is arranged above the frame, and the adjustable roller is arranged below the fixed roller, so that the cigarette paper strip runs in an S-path between the fixed roller and the adjustable roller.

[0018] Furthermore, the drive mechanism includes a servo motor and a mounting plate. The adjustable roller is fixed in the mounting plate, and the servo motor drives the mounting plate to move the adjustable roller in a direction that is closer to or farther from the fixed roller.

[0019] Furthermore, the drive mechanism also includes a slider and a slide rail. The mounting plate is connected to the slider, and the servo motor drives the slider to slide on the slide rail, thereby causing the adjustable roller in the mounting plate to move.

[0020] Furthermore, the drive mechanism also includes a lead screw and a lead screw nut. The lead screw nut is fixedly connected to the slider. The servo motor is connected to the lead screw and can drive the lead screw to rotate, thereby causing the lead screw nut to drive the slider to move on the lead screw.

[0021] Furthermore, the heating and temperature control system includes a heating element.

[0022] The fixed roller and the adjustable roller have mounting grooves evenly distributed circumferentially inside. Heating elements are set in the mounting grooves to heat the surfaces of the fixed roller and the adjustable roller, thereby performing a first heating treatment and a second heating treatment on the cigarette paper strip.

[0023] Furthermore, the heating and temperature control system also includes a temperature sensor, which is connected to both a fixed roller and an adjustable roller to collect surface temperature.

[0024] Furthermore, the heating and temperature control system also includes a temperature control module, which is connected to a temperature sensor to adjust the power of the heating element according to the surface temperature.

[0025] Furthermore, the temperature sensor includes a thermocouple, which is disposed on the surfaces of the fixed roller and the adjustable roller.

[0026] Furthermore, the outer surfaces of both the fixed roller and the adjustable roller are coated with a high-temperature resistant and anti-slip coating.

[0027] In this patented process, a fixed roller and an adjustable roller work together to drive the paper tape forward during paper tape production. The fixed roller remains stationary, serving as a fixed support point for the paper tape's movement; the adjustable roller, under the action of the drive mechanism, works in conjunction with the fixed roller to ensure the paper tape moves forward stably and continuously, according to the needs of the paper tape's movement.

[0028] This patent further adjusts the heating time by changing the winding method of the paper tape with the fixed and adjustable rollers, thereby adjusting the contact area between the paper tape and the rollers. When it is necessary to increase the heating time of the paper tape, the winding path of the paper tape on the two rollers can be adjusted, so that the adjustable roller moves downward to increase the distance between the fixed and adjustable rollers, increasing the heating contact length between the paper tape and the rollers, thereby increasing the heat contact area and prolonging the residence time of the paper tape on the rollers for heating, thus absorbing more heat and achieving the purpose of increasing the heating time. Conversely, if it is necessary to reduce the heating time, the contact area between the paper tape and the rollers can be reduced, that is, the adjustable roller moves upward to shorten the distance between the fixed and adjustable rollers, shortening the residence time of the paper tape on the rollers for heating, and reducing heat absorption.

[0029] The heating time of the paper tape directly affects its thickness. A longer heating time results in a higher degree of heating, causing corresponding changes in material properties and affecting the thickness; a shorter heating time results in a lower degree of heating, also altering the thickness. This patent controls the heating time by precisely adjusting the contact area between the paper tape and the roller, ultimately achieving effective control over the paper tape thickness.

[0030] This patent provides a tobacco paper tape thickness adjustment device, which controls the winding path of the tobacco paper tape through a roller assembly. The thickness of the tobacco paper tape is adjusted by heating the tobacco paper tape using fixed rollers and adjustable rollers, thereby achieving fine control of the thickness of the tobacco paper tape. This eliminates the need to rely on large changes in rotation speed or temperature, avoiding the problem of unstable thickness control caused by speed fluctuations or temperature overshoot in traditional methods.

[0031] Compared with the prior art, this patent has the following advantages:

[0032] 1. Ensuring heating uniformity and thickness consistency

[0033] The surface-heatable and temperature-controlled roller design provides a stable and uniform heating environment for the paper tape. The temperature of the two rollers can be independently and precisely controlled. Combined with the large-area contact heating formed by the winding path adjustment, it avoids the paper tape thickness fluctuation problem caused by traditional single-point heating or non-uniform heating, ensuring that the thickness consistency of the paper tape in both the transverse and longitudinal directions reaches a high standard.

[0034] 2. The flexibility and adaptability of dynamic adjustment

[0035] The adjustable roller slide block drive mechanism supports automatic dynamic adjustment of the distance between the two rollers. Combined with the diverse winding methods, it can quickly respond to the production needs of paper tapes with different materials and initial thicknesses. Without changing the hardware, flexible production of multiple specifications can be achieved simply by adjusting the winding path and roller distance through the control program, significantly reducing production line changeover costs.

[0036] 3. Precise quantitative control of heating time

[0037] Unlike traditional heating control methods that rely on sudden changes in roller speed or temperature, this patent achieves linear adjustment of heating time through geometric adjustment of the contact area. Operators can, according to process requirements, increase or decrease the number of paper rolls around the roller surface and change the winding angle, thereby improving the precision of heating time control to the second or even millisecond level, without altering the roller speed and temperature. This provides a precise process control method for the production of heat-sensitive materials or special paper rolls sensitive to temperature-time curves.

[0038] 4. Improved equipment stability and production efficiency

[0039] The coordinated drive structure of fixed and adjustable rollers, combined with the high-precision guiding design of the slide rail mechanism, effectively reduces problems such as offset and wrinkles during paper tape travel, ensuring operational stability in high-speed production environments. Meanwhile, the automatic spacing adjustment function requires no manual intervention.

[0040] 5. Energy saving, consumption reduction and ease of maintenance

[0041] The modular design of the adjustable rollers eliminates the need for complete disassembly during equipment maintenance. Only the slide rail slider assembly or heating unit needs to be replaced independently, significantly reducing downtime for maintenance. Attached Figure Description

[0068] like Figure 1-4As shown, this patent provides a cigarette paper tape thickness adjustment device, including a frame 4, a roller assembly, a drive mechanism 3, a roller heating and temperature control system (not shown in the figure), and a control system (not shown in the figure). The roller assembly includes a fixed roller 1 and an adjustable roller 2 mounted on the frame 4. The drive mechanism 3 drives the adjustable roller 2 to move, thereby changing the winding method of the paper tape on the two rollers and adjusting the contact area. Combined with the adjustment of the roller spacing, the heating time of the paper tape is controlled, thereby controlling the thickness of the paper tape. The cigarette paper tape thickness adjustment device of this patent may also include a paper tape conveying device and a conveyor device. Both the conveying device and the conveyor device can be conveyor belt-type power traction devices. The conveying device is used to guide the cigarette paper tape into the fixed roller 1 and transfer it to the adjustable roller 2. The conveyor device removes the heated portion of the paper tape from the adjustable roller 2 from the cigarette paper tape thickness adjustment device for the next production process.

[0069] Roller assembly

[0070] The roller assembly is equipped with two rollers whose surfaces can be heated and temperature controlled, namely a fixed roller 1 and an adjustable roller 2. Both the fixed roller 1 and the adjustable roller 2 are connected to the roller heating and temperature control system, so that the rollers have a heating function at least on the contact surface with the paper tape. Their surface temperature can be precisely controlled according to production needs, providing a stable heat source for the heating treatment of the paper tape.

[0071] The fixed roller 1 is horizontally installed above the frame 4. The two ends of the fixed roller shaft are fixed to the frame 4 through the fixed bearing seats 11. The main body of the roller is a hollow cylinder with a high-temperature resistant anti-slip coating on the outer surface, such as carbon-based lubricating material or fluoropolymer-based material. The heating element mounting grooves (not shown in the figure) are evenly distributed in the circumference inside, so that the surface temperature of the heating roller can reach up to 100°C.

[0072] Adjustable roller 2 is arranged parallel to fixed roller 1 below frame 4. The outer surface of adjustable roller 2 is coated with a high-temperature resistant, anti-slip coating, such as a carbon-based lubricating material or a fluoropolymer-based material. Both ends of the adjustable roller shaft are connected to mounting plate 31 of drive mechanism 3. Mounting plate 31 is connected to linear slide rail 33 on frame 4 via slider 32 of drive mechanism 3. Slider 32 can slide up and down along slide rail 33. Adjustable roller 2 and fixed roller 1 have identical structures and both have independent heating and temperature control functions, allowing simultaneous heating of the paper tape. The running path of the paper tape on adjustable roller 2 and fixed roller 1 is an S-curve, meaning the paper tape does not completely circle the circumference of adjustable roller 2 and fixed roller 1.

[0073] Drive mechanism

[0074] The adjustable roller 2 is connected to a drive mechanism 3 with a slide rail 33 and a slider 32. This drive mechanism 3 enables the positional movement of the adjustable roller 2, thereby automatically adjusting the distance between the adjustable roller 2 and the fixed roller 1. The design of the drive mechanism 3 ensures the accuracy and stability of the distance adjustment, allowing for flexible adjustment of the distance between the two rollers according to different paper tape processing requirements.

[0075] The slide rails 33 in the drive mechanism 3 are set as two straight slide rails 33, which are fixed in the frame 4 in the vertical direction, and the slider 32 is fixedly connected to the mounting plate 31 of the adjustable roller 2.

[0076] The drive mechanism 3 includes a power unit. In this embodiment, the power unit is a servo motor 34. The servo motor 34 is connected to a lead screw nut via a reducer. The lead screw is arranged along the slide rail 33, and the lead screw nut is fixedly connected to the slider 32. The servo motor 34 receives a control system signal and drives the lead screw to rotate. Under the drive of the lead screw, the lead screw nut drives the slider 32 to move upward (i.e., the adjustable roller 2 is closer to the fixed roller 1) or downward (i.e., the adjustable roller 2 is farther away from the fixed roller 1) along the slide rail 33, thereby realizing the automatic adjustment of the distance between the adjustable roller 2 and the fixed roller 1.

[0077] The drive mechanism 3 may also be equipped with a connecting device for the paper tape from the fixed roller 1 to the adjustable roller 2, ensuring the contact area between the paper tape and the adjustable roller 2, thereby controlling the heating time of the paper tape. As an example, the connecting device is a blower device located between the fixed roller 1 and the adjustable roller 2, and the paper tape coming out of the fixed roller 1 is connected to the adjustable roller 2 by the force of the blower.

[0078] Heating and temperature control system

[0079] The heating and temperature control system is used to control the temperature of the contact surfaces between the fixed roller 1 and the adjustable roller 2 and the paper tape, and includes heating elements, temperature sensors and temperature control modules.

[0080] The heating elements are embedded in the mounting slots of the fixed roller 1 and the adjustable roller 2 respectively. The heating rods are evenly distributed along the roller axis to ensure that the roller surface temperature is uniform.

[0081] The temperature sensor consists of thermocouples installed on the surfaces of the fixed roller 1 and the adjustable roller 2, which collect the surface temperature of the rollers in real time and feed it back to the temperature control module.

[0082] The temperature control module receives signals from the temperature sensor and adjusts the heating element power through algorithms or manual adjustment by the operator to keep the roller surface temperature stable within the set range.

[0083] If necessary, tension sensors can also be installed: tension sensors are installed at the paper tape inlet and outlet to monitor the paper tape tension in real time and feed it back to the control system to ensure stable tension during the paper tape's movement.

[0084] Working principle:

[0085] The initial state is set according to the target paper tape thickness and material. The target temperature of the fixed roller 1 and the adjustable roller 2 is set by the control system. The heating and temperature control system is started to raise the temperature of the rollers to the set temperature.

[0086] Servo motor 34 drives the adjustable roller 2 to move, so that the initial distance between the fixed roller 1 and the adjustable roller 2 meets the initial feeding requirements of the paper tape, and the paper tape is wound on the fixed roller 1 and the adjustable roller 2 at a preset angle respectively.

[0087] The paper tape enters from the inlet end, first passes through the tension sensor to detect the tension, and then passes around the fixed roller 1 and the adjustable roller 2 in sequence to form a specific winding path, and finally exits from the outlet end.

[0088] When it is necessary to increase the heating time, refer to... Figure 3 The control system sends a command: by adjusting the paper tape winding path, the heating contact length of the paper tape on the surfaces of the two rollers is increased. During the paper tape operation, the servo motor 34 can drive the adjustable roller 2 to move at any time, appropriately increasing the distance between the two rollers to provide sufficient space for the paper tape winding, avoiding stretching and deformation of the paper tape due to excessive contact. Since both the fixed roller 1 and the adjustable roller 2 are connected to the heating and temperature control system to heat the paper tape, the middle area between the fixed roller 1 and the adjustable roller 2 also continuously heats the paper tape. In this way, the middle area between the fixed roller 1 and the adjustable roller 2 constitutes part of the heating contact length, which increases the running path length of the paper tape on the fixed roller 1 and the adjustable roller 2, thereby increasing the heating time of the paper tape.

[0089] Conversely, if you need to reduce the heating time, refer to... Figure 4 This requires shortening the heating contact length, thereby reducing the running path length of the paper tape on the fixed roller 1 and the adjustable roller 2, and correspondingly reducing the distance between the fixed roller 1 and the adjustable roller 2.

[0090] The heating and temperature control system provides closed-loop control of the paper tape. A thickness sensor at the exit end monitors the tape thickness in real time and feeds the data back to the control system. This drives the adjustable roller 2 to move and adjust the spacing, forming a closed-loop control system of detection, adjustment, and feedback to ensure the paper tape thickness remains stable within the target range.

[0091] This embodiment achieves stepless adjustment of the heating time of the paper tape through adjustable-gap heating rollers and a flexible winding path design. It eliminates the need for significant changes in rotation speed or temperature, avoiding the thickness control instability caused by speed fluctuations or temperature overshoot in traditional methods. Simultaneously, the modular drive mechanism 3 allows the equipment to quickly adapt to the production of paper tapes of different specifications, improving production flexibility while ensuring control accuracy.

[0092] This patent has the following beneficial effects:

[0093] 1. Ensuring heating uniformity and thickness consistency

[0094] The surface-heatable and temperature-controlled roller design provides a stable and uniform heating environment for the paper tape. The temperature of the two rollers can be independently and precisely controlled. Combined with the large-area contact heating formed by the winding path adjustment, it avoids the paper tape thickness fluctuation problem caused by traditional single-point heating or non-uniform heating, ensuring that the thickness consistency of the paper tape in both the transverse and longitudinal directions reaches a high standard.

[0095] 2. The flexibility and adaptability of dynamic adjustment

[0096] The adjustable roller slide block drive mechanism supports automatic dynamic adjustment of the distance between the two rollers. Combined with the diverse winding methods, it can quickly respond to the production needs of paper tapes with different materials and initial thicknesses. Without changing the hardware, flexible production of multiple specifications can be achieved simply by adjusting the winding path and roller distance through the control program, significantly reducing production line changeover costs.

[0097] 3. Precise quantitative control of heating time

[0098] Unlike traditional heating control methods that rely on sudden changes in roller speed or temperature, this patent achieves linear adjustment of heating time through geometric adjustment of the contact area. Operators can, according to process requirements, increase or decrease the number of paper rolls around the roller surface and change the winding angle, thereby improving the precision of heating time control to the second or even millisecond level, without altering the roller speed and temperature. This provides a precise process control method for the production of heat-sensitive materials or special paper rolls sensitive to temperature-time curves.

[0099] 4. Improved equipment stability and production efficiency

[0100] The coordinated drive structure of fixed and adjustable rollers, combined with the high-precision guiding design of the slide rail mechanism, effectively reduces problems such as offset and wrinkles during paper tape travel, ensuring operational stability in high-speed production environments. Meanwhile, the automatic spacing adjustment function requires no manual intervention.

[0101] 5. Energy saving, consumption reduction and ease of maintenance

[0102] The modular design of the adjustable rollers eliminates the need for complete disassembly during equipment maintenance. Only the slide rail slider assembly or heating unit needs to be replaced independently, significantly reducing downtime for maintenance.
