Description

Technical Field

[0001] This utility model relates to the field of specialty paper technology, specifically a paper roll translation mechanism for specialty paper production. Background Technology

[0002] Specialty paper is a category of specialized paper products that differs from traditional traditional paper and packaging paper. It is made by selecting special fiber raw materials, such as modified plant fibers, synthetic fibers, and mineral fibers, or by using special processing techniques such as coating, lamination, embossing, impregnation, and vacuum forming. Its core characteristics are customized functional attributes and adaptability to specific usage scenarios. According to function, it can be divided into waterproof and oil-proof, flame-retardant and high-temperature resistant, antibacterial and protective, conductive and thermally conductive, anti-counterfeiting and confidential, and filtration and separation types. Typical products include medical sterile packaging paper, electronic-grade insulating paper, food contact oil-proof paper, anti-counterfeiting watermark paper, and industrial filter paper.

[0003] After the paper roll is rewound, it needs to be accurately conveyed to the rewinder unwinding rack. The current mainstream conveying solution adopts a slanted rail hydraulic cylinder pushing structure, but this structure has exposed many key technical problems in actual production: Firstly, as the diameter of the finished roll increases, its inertia and weight increase in a positive correlation. If the tilt angle of the inclined rail is not designed properly, it will lead to a surge in the downward impact of the paper roll, which places extremely high demands on the impact resistance, buffer stroke and response speed of the end buffer device, and may easily cause damage to the buffer or the end face of the paper roll. Secondly, the inclination angles on both sides of the inclined rail must be kept strictly consistent. If there are processing errors or installation deviations, it will cause uneven force on both sides of the paper roll and asynchronous conveying, which will lead to quality problems such as paper roll offset and end face wrinkling. Moreover, the inclination angle of the inclined rail is difficult to correct, resulting in high maintenance costs. Thirdly, even with a proportional control valve, the thrust of the hydraulic cylinder on both sides is still difficult to achieve absolute synchronization, which can easily lead to jamming or skewing of the paper roll during the inclined rail conveying process, directly affecting the conveying efficiency and the smooth connection of subsequent processes.

[0004] Therefore, we propose a paper roll translation mechanism for special paper production. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a paper roll translation mechanism for special paper production, which can effectively solve the problems in the prior art.

[0006] The technical solution adopted by this utility model is: a paper roll translation mechanism for special paper production, including a frame base, a crossbeam fixedly installed at the top of the frame base, a guide rail fixedly installed at the upper end of the crossbeam, a paper roll slidably installed above the crossbeam via the guide rail, a translation mechanism provided on the outer side of the crossbeam, a fixed seat fixedly installed on the outer side of the crossbeam via the translation mechanism, a lever fixedly installed on the side of the fixed seat away from the translation mechanism, a rotating shaft rotatably installed at the opening at the top of the lever, and a roller rotatably installed at the opening at the top of the lever via the rotating shaft.

[0007] Preferably, there are multiple identical frame seats, which are evenly distributed at intervals on the lower part of the crossbeam. There are two identical crossbeams, and the number of frame seats is four times that of the crossbeam. The guide rails are symmetrically distributed on both sides of the paper roll.

[0008] Through the above technical solution, the combination of double crossbeams and double guide rails forms a double guide limiting structure, which can effectively constrain the movement trajectory of the paper roll and prevent the paper roll from deviating due to unilateral force during the conveying process, thus achieving smooth translation.

[0009] Preferably, the translation mechanism, fixed seat, lever, rotating shaft and roller are provided in two identical sets, and the translation mechanism, fixed seat, lever, rotating shaft and roller in each set are symmetrically distributed about the vertical axis of the crossbeam, and the roller is in contact with the paper roll.

[0010] Through the above technical solution, the design of the double-sided symmetrical mechanism can achieve balanced force on the paper roll, completely solving the problem of uneven force caused by traditional single-sided drive. The contact connection between the roller and the paper roll transforms the traditional sliding friction into rolling friction.

[0011] Preferably, the translation mechanism includes a guide rail and a rack fixedly installed with the crossbeam. A slider is slidably installed on the outer side of the guide rail. A main moving plate is fixedly installed on the side of the slider away from the guide rail. A geared motor is fixedly installed on the outer side of the main moving plate. A main drive shaft is fixedly installed at the output end of the geared motor. A drive gear is fixedly installed at the end of the main drive shaft away from the geared motor.

[0012] The above technical solution adopts a combination of guide rail slider and gear rack transmission to replace the traditional hydraulic drive structure. This avoids the defect of poor synchronization of hydraulic system from the perspective of transmission principle. The geared motor directly drives the gear to rotate through the main drive shaft. With the guide rail guiding and limiting the main moving plate, the trajectory control of the translation mechanism can be realized.

[0013] Preferably, the number of sliders is four times that of the main moving plate, and they are distributed diagonally in an X-shape about the horizontal axis of the main moving plate, and the drive gear and the rack are meshed.

[0014] Through the above technical solution, the X-shaped diagonally distributed sliders can support the main moving plate from four force points, significantly improving the torsional resistance and load-bearing capacity of the main moving plate.

[0015] Compared with the prior art, this utility model provides a paper roll translation mechanism for special paper production, which has the following beneficial effects: 1. This special paper roll translation mechanism for production utilizes the synchronous advantage of gear and rack meshing transmission. Combined with the precise speed control of the geared motor, it can accurately control the translation distance of the paper roll, avoiding translation errors caused by leakage and pressure fluctuations that are prone to occur in hydraulic systems. The rolling friction between the rollers and the paper roll is more stable than traditional sliding friction, making it particularly suitable for special paper production scenarios with sensitive surfaces and high precision requirements. The combination of double crossbeams and double guide rails forms a double guide limit structure, which can effectively constrain the movement trajectory of the paper roll and prevent the paper roll from deviating due to unilateral force during conveying, thus achieving smooth translation.

[0018] 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.

[0019] Example 1: As Figure 1-6 As shown, the present invention provides a paper roll translation mechanism for special paper production, including a frame base 1, a crossbeam 2 fixedly installed at the top of the frame base 1, a guide rail 3 fixedly installed at the upper end of the crossbeam 2, a paper roll 4 slidably installed above the crossbeam 2 via the guide rail 3, a translation mechanism 5 provided on the outer side of the crossbeam 2, a fixed seat 6 fixedly installed on the outer side of the crossbeam 2 via the translation mechanism 5, a lever 7 fixedly installed on the side of the fixed seat 6 away from the translation mechanism 5, a rotating shaft 8 rotatably installed at the opening at the top of the lever 7, and a roller 9 rotatably installed at the opening at the top of the lever 7 via the rotating shaft 8.

[0020] Specifically, multiple identical frame bases 1 are provided, and these frame bases 1 are evenly distributed at intervals under the crossbeams 2. Two identical crossbeams 2 are provided, and the number of frame bases 1 is four times that of the crossbeams 2. Guide rails 3 are symmetrically distributed on both sides of the paper roll 4. The advantage is that the combination of the double crossbeams 2 and the double guide rails 3 forms a double-guide limiting structure, which can effectively constrain the movement trajectory of the paper roll 4, prevent paper roll deviation caused by unilateral force during conveying, and achieve smooth translation.

[0021] Specifically, the translation mechanism 5, fixed seat 6, lever 7, rotating shaft 8, and roller 9 are arranged in two identical sets. Each set of translation mechanism 5, fixed seat 6, lever 7, rotating shaft 8, and roller 9 is symmetrically distributed about the vertical axis of the crossbeam 2. The roller 9 is in contact with the paper roll 4. The advantage is that the symmetrical design of the mechanism on both sides can achieve balanced force on the paper roll 4, completely solving the problem of uneven force distribution that is easily caused by traditional single-sided drive. The contact connection between the roller 9 and the paper roll 4 transforms the traditional sliding friction into rolling friction.

[0022] Example 2: like Figure 2-6 As shown, this is an improvement on the previous embodiment.

[0023] Specifically, the translation mechanism 5 includes a guide rail 507 and a rack 505 fixedly installed with the crossbeam 2. A slider 506 is slidably installed on the outer side of the guide rail 507. A main moving plate 501 is fixedly installed on the side of the slider 506 away from the guide rail 507. A geared motor 502 is fixedly installed on the outer side of the main moving plate 501. A main drive shaft 503 is fixedly installed at the output end of the geared motor 502. A drive gear 504 is fixedly installed at the end of the main drive shaft 503 away from the geared motor 502. The advantage is that the combined transmission form of the guide rail 507, slider 506, and rack and pinion 505 replaces the traditional hydraulic drive structure. From the perspective of transmission principle, it avoids the defect of poor synchronization of the hydraulic system. The geared motor 502 directly drives the gear 504 to rotate through the main drive shaft 503. With the guiding and limiting effect of the guide rail 507 on the main moving plate 501, the trajectory control of the translation mechanism 5 can be realized.

[0024] Specifically, the number of sliders 506 is four times that of the main moving plate 501, and they are distributed diagonally in an X-shape about the transverse axis of the main moving plate 501. The drive gear 504 and the rack 505 are meshed together. The advantage is that the X-shaped diagonally distributed sliders 506 can support the main moving plate 501 from four force points, significantly improving the torsional resistance and load-bearing capacity of the main moving plate 501.

[0025] Working principle: When in use, the reduction motor 502 in the translation mechanism 5 is started. The reduction motor 502 transmits power to the drive gear 504 through the main drive shaft 503. The drive gear 504 meshes with the rack 505 fixed to the crossbeam 2, thereby driving the main moving plate 501 to move linearly along the guide rail 507. The X-shaped sliders 506 ensure that the main moving plate 501 does not deviate or twist during the movement. The main moving plate 501 drives the lever 7 to move synchronously through the fixed seat 6. The roller 9 at the top of the lever 7 is in contact with the paper roll 4. When it moves with the lever 7, it drives the paper roll 4 to move smoothly along the guide rail 3 through rolling friction. The translation mechanism 5, which is symmetrically distributed on both sides, moves synchronously to achieve balanced and stable displacement of the paper roll 4 and the paper roll.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
