Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of special paper production, and specifically relates to a self-adaptive calendering control device for special paper production. BACKGROUND

[0002] Special paper is more complex in production process than ordinary paper due to its unique material and functional requirements. Special paper needs to adjust moisture according to functions and may be pre-coated with a functional coating layer. For example, waterproof paper needs to be impregnated with a hydrophobic agent before calendering, and high-temperature-resistant paper needs to ensure the heat-resistant stability of fibers. When special paper is subjected to calendering treatment, multiple groups of rollers are alternately rolled to ensure the tightness and smoothness of the paper and can heat the rollers to 80-200 DEG C to soften the fibers and close the surface pores. Some special paper needs to be sprayed with silicone oil or wax-based calendering oil during calendering to improve water resistance and wear resistance.

[0003] Traditional calendering equipment is mostly designed in one piece, which makes it difficult to maintain or adjust the calendering machine locally. When loading the traditional calendering machine, it is difficult to adjust a single roller separately due to the one-piece design, which requires manual adjustment of the paper according to all the rollers during loading. The back-and-forth disassembly and assembly of the paper cause mechanical scratches and paper damage. Therefore, a self-adaptive calendering control device for special paper production is developed. SUMMARY

[0004] To solve the problems in the background art, the application provides a self-adaptive calendering control device for special paper production.

[0005] To achieve the above-mentioned purposes, the application provides the following technical scheme: a self-adaptive calendering control device for special paper production, comprising two ends of a main support frame, and further comprising: Two ends of a calendering assembly are installed inside the two ends of the main support frame for calendering treatment of the paper itself.

[0006] Preferably, guide rails are provided inside both ends of the movable support plates, and both ends of a pair of movable support plates are distributed in a C-shape with opposite openings, and both ends of a servo motor are fixedly connected inside both ends of a movable support plate.

[0007] Preferably, the two ends of the movable support plate are located on the lower side of the two ends of the high-temperature steam roller, and the two ends of the high-temperature steam roller are fixedly connected to the two ends of the sliding support block. The two ends of the high-temperature steam roller are installed with two ends of the steam valve, and the two ends of the high-temperature steam roller are externally connected to the steam delivery mechanism. The two ends of the steam valve extend outward at 45° upward, and the two ends of the high-temperature steam roller and the two ends of the movable support plate are horizontally distributed, and the center lines of the two are in the same horizontal plane.

[0008] Preferably, the two ends of the sliding support block slide on the two ends of the movable support plate through the guide rails inside the two ends of the movable support plate. The two ends of the sliding support block are L-shaped, and the horizontal rod parts are both located on the side facing the two ends of the paper pulp roller at both ends of the sliding support block, and the two ends of the adjustment threaded rod are located at one end of the horizontal rod at both ends of the sliding support block.

[0009] Preferably, the two ends of the adjusting threaded rod are located on the lower side of the two ends of the movable support plate, and the two ends of the adjusting threaded rod are rotatably connected to the two ends of the movable support plate. At the same time, the two ends of the first gear are located on the outside of the two ends of the movable support plate, and the two ends of the first gear are provided with hexagonal holes.

[0010] Preferably, the two ends of the first gear are meshedly connected with the two ends of the second gear, and the two ends of the second gear are internally slidably connected with the two ends of the locking bolt, and the two ends of the locking bolt include a screw and a nut, wherein the nut part is fixedly connected to the inner side of the two ends of the movable support plate, wherein the screw part penetrates the two ends of the movable support plate and is threadedly connected to the nut, and the two ends of the second gear are rotatably connected to the middle part of the screw.

[0011] Preferably, the two ends of the first gear drive the two ends of the adjusting threaded rod to rotate, so that the two ends of the adjusting threaded rod drive the two ends of the sliding support block to move toward each other along the internal guide rails at both ends of the movable support plate, so that the two ends of the sliding support block can drive the two ends of the high-temperature steam roller to move to close or open.

[0012] Preferably, both ends of the vertical adjustment assembly include two ends of a double-headed cylinder fixedly connected to the two ends of the movable support plate, both ends of the double-headed cylinder penetrate the two ends of the movable support plate and extend respectively to the two ends of a pair of limiting slide grooves opened inside the two ends of the movable support plate, the two ends of the limiting slide groove are internally slidably connected to the two ends of the support slider, the bottom of the two ends of the support slider are hinged to the two ends of the support rod, and the bottom of the two ends of the support rod are hinged to the two ends of the support base.

[0013] Preferably, both ends of the double-headed cylinder are fixedly connected to the inside of the openings at both ends of the movable support plate, both ends of the support base are fixedly connected to the two ends of the movable support plate at the bottom of both ends of the movable support plate or the two ends of the main support frame, both ends of the double-headed cylinder are fixedly connected to the two ends of the support slider, and the two ends of the support rod are distributed in an eight-shaped shape that opens downward.

At this time, the two ends of the support sliders will drive one end of the support rod to move synchronously, causing the two ends of the support rod to flip, thereby pushing the two ends of the movable support plate up or pulling the two ends of the movable support plate down.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention cooperates with structures such as a tension adjustment component and a vertical adjustment component to facilitate the adjustment of the paper between a pair of rollers during feeding. The two ends of the double-headed cylinder push the two ends of the support slider to move to both sides along the two ends of the limit slide to open, so that the two ends of the support rod flip and pull the two ends of a group of movable support plates to drive the two ends of the paper pulp roller to move downward to clamp the paper. Then, the two ends of the threaded rod drive the two ends of the sliding support block to drive the two ends of the high-temperature steam roller to move and open to stretch the paper. In this way, by independently controlling the movement of the two ends of the pair of paper pulp rollers and the opening and closing of the two ends of the high-temperature steam roller, the tension of the paper at the two ends of a group of calendering components can be independently controlled, thereby saving the steps of adjusting the paper multiple times according to the overall process, improving efficiency and reducing losses. The present invention cooperates with structures such as a vertical adjustment component and a movable support plate to independently control the movement of two ends of a group of movable support plates. Through a connecting mechanism consisting of two ends of a support base, two ends of a support rod and two ends of a support slide connected at both ends of a pair of movable support plates, the two ends of the movable support plate can be independently extended and retracted by two ends of a double-headed cylinder installed inside, thereby pushing the movement of the two ends of the movable support plate, thereby realizing independent adjustment of the two ends of the paper pulp roller. Compared with the integral disassembly of an integrated system, the present invention is more flexible and practical. The present invention cooperates with structures such as a tension adjustment component and a high-temperature steam roller, thereby facilitating the movement of the two ends of the high-temperature steam roller by the two ends of the tension adjustment component to adjust the tension of the paper. By adjusting the two ends of the threaded rod, the two ends of the sliding support blocks at the two ends drive the two ends of the high-temperature steam roller to move closer to or away from the two ends of the movable support plate, thereby controlling the distance between the two ends of the high-temperature steam roller and the two ends of the paper pulp roller, so that after the paper is fixed at the two ends of the paper pulp roller, the tension of the paper on both sides of the paper pulp roller can be adjusted by moving the two ends of the high-temperature steam roller.

[0018] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0019] As Figures 1 to 8 shown, the present application provides a self-adaptive calendering control device for special paper production, which comprises a main support frame 1, and further comprises: a calender assembly 2 installed inside the main support frame 1, used for calendering the paper itself; a tension adjustment assembly 3 arranged at both ends of the calender assembly 2, used for adjusting the tightness of the paper; a vertical adjustment assembly 4 arranged between a pair of calender assemblies 2, used for adjusting the distance between the pair of calender assemblies 2; The calendering assembly 2 includes movable support plates 201 respectively mounted on the support columns on both sides of the main support frame 1. A paper pulp roller 202 is movably connected to the middle of the pair of movable support plates 201. High-temperature steam rollers 203 are provided on both sides of the paper pulp roller 202. The tension adjustment assembly 3 includes a pair of sliding support blocks 301 movably connected to the movable support plate 201 . An adjusting threaded rod 302 is threadedly connected to the middle of the pair of sliding support blocks 301 . One end of the adjusting threaded rod 302 is fixedly connected to a first gear 303 .

[0020] The above solution is adopted: by screwing the first gears 303 at both ends of the high-temperature steam roller 203, the adjusting threaded rod 302 is driven to rotate, so that the adjusting threaded rod 302 drives the sliding support block 301 to drive the high-temperature steam roller 203 to move to adjust the distance between the high-temperature steam roller 203 and the paper pulp roller 202. By controlling the movement of the high-temperature steam roller 203, the tension of the paper is controlled to ensure the calendering effect of the paper. Finally, the equipment can be started to perform calendering treatment on the paper.

[0021] like Figures 1 to 4 As shown, a guide rail is arranged inside the movable support plate 201, and a pair of movable support plates 201 are distributed in a C-shape with opposite openings.

The steam valve 204 extends outward at an angle of 45° upward. The high-temperature steam roller 203 and the movable support plate 201 are distributed horizontally, and the center lines of the two are in the same horizontal plane.

[0022] The above scheme is adopted: by setting up a calendering assembly 2, a movable support plate 201 is slidably connected to the main support frame 1, which can facilitate the movable support plate 201 to drive the paper pulp roller 202 and the high-temperature steam roller 203 to move up and down, thereby adjusting the position of the paper pulp roller 202, which can facilitate the placement of paper or adjust the distance between the paper pulp rollers 202 according to the thickness of the paper.

Through the steam valve 204 provided on the high-temperature steam roller 203, steam can be supplied to the inside of the high-temperature steam roller 203 to heat the paper according to whether hot pressing is required according to the characteristics of the paper. By setting the steam valve 204 upward at 45°, it is convenient to turn the steam valve 204. The setting of the steam conveying mechanism can convey steam to the inside of the high-temperature steam roller 203, which can heat the paper when the paper passes through the high-temperature steam roller 203.

[0023] like Figures 2 to 4 As shown, the sliding support block 301 slides on the movable support plate 201 through the guide rail inside the movable support plate 201. The sliding support block 301 is L-shaped, and its horizontal rod parts are all located on the side of the sliding support block 301 facing the paper pulp roller 202. The adjusting threaded rod 302 is located at one end of the horizontal rod of the sliding support block 301, and the adjusting threaded rod 302 is located on the lower side of the movable support plate 201. The adjusting threaded rod 302 is rotatably connected to the movable support plate 201. At the same time, the first gear 303 is located on the outside of the movable support plate 201, and a hexagonal hole is provided inside the first gear 303.

[0024] The above scheme is adopted: by setting the tension adjustment component 3, it is convenient to adjust the high-temperature steam roller 203 to move toward each other, so that the high-temperature steam roller 203 stretches the paper, simplifying the process of adjusting the tightness of the paper, and by setting the sliding support block 301 and the adjustment threaded rod 302, the adjustment threaded rod 302 drives the sliding support block 301 to move synchronously, so as to facilitate the adjustment of the position of the high-temperature steam roller 203, and the first gear 303 set at the end of the adjustment threaded rod 302 can be conveniently turned to rotate the adjustment threaded rod 302, thereby driving the sliding support block 301 to move, and the hexagonal hole opened on the first gear 303 can facilitate the first gear 303 to be screwed by a tool.

[0025] like Figures 3 to 6 As shown, the first gear 303 is meshedly connected to the second gear 304, and the locking bolt 305 is slidably connected inside the second gear 304.

[0026] The above solution is adopted: by setting a second gear 304 and a locking bolt 305, the second gear 304 rotates synchronously with the first gear 303, and then the second gear 304 is squeezed and fixed by the locking bolt 305, so that the second gear 304 cannot rotate, and then the first gear 303 is locked by the second gear 304, and then the adjusting threaded rod 302 is locked, so that the adjusting threaded rod 302 cannot rotate, thereby achieving the fixation of the sliding support block 301, so that the high-temperature steam roller 203 remains fixed after the adjustment is completed.

[0027] like Figures 3 to 6 As shown, the first gear 303 drives the adjusting threaded rod 302 to rotate, so that the adjusting threaded rod 302 drives the sliding support block 301 to move toward each other along the guide rail inside the movable support plate 201, so that the sliding support block 301 can drive the high-temperature steam roller 203 to move closed or opened.

[0028] The above solution is adopted: when the first gear 303 drives the adjusting threaded rod 302 to rotate, the adjusting threaded rod 302 will drive the sliding support blocks 301 at both ends to move along the guide rail inside the movable support plate 201 to close or open. At this time, the sliding support blocks 301 located at both ends of the high-temperature steam roller 203 can drive the high-temperature steam roller 203 to move closer to or away from the movable support plate 201, thereby controlling the distance between the high-temperature steam roller 203 and the paper pulp roller 202, so as to adjust the tension of the paper by moving the high-temperature steam roller 203.

[0030] The above scheme is adopted: by setting up a vertical adjustment component 4, it is convenient to drive the movable support plate 201 to move, so as to control the movement of the paper pulp rollers 202 to adjust the distance between each other; by setting up a double-headed cylinder 401, it is convenient to push the support slider 403 to move synchronously, so as to adjust the flipping degree of the support rod 404 through the stable movement of the support slider 403, thereby controlling the rise or fall of the movable support plate 201; at the same time, the vertical adjustment component 4 corresponding to each movable support plate 201 enables the distance between a pair of paper pulp rollers 202 to be adjusted individually as needed, so as to facilitate paper adjustment or maintenance and inspection of individual paper pulp rollers 202.

[0031] like Figure 7 and Figure 8 As shown, the double-headed cylinder 401 drives the support sliders 403 at both ends to slide synchronously inside the limiting slide groove 402. At this time, the support slider 403 will drive one end of the support rod 404 to move synchronously, causing the support rod 404 to flip, thereby pushing the movable support plate 201 up or pulling the movable support plate 201 down.

[0032] Adopt the above scheme: when the double-head cylinder 401 is elongated to push the support sliding block 403 at both ends to slide in the limiting sliding groove 402, at this time, the support sliding block 403 will drive the support rod 404 to move, so that the support rod 404 is turned over, the support rod 404 pushes the movable support plate 201 to rise, the movable support plate 201 drives the paper pulp roller 202 to move synchronously, so that the corresponding paper pulp roller 202 is away from the lower paper pulp roller 202, and vice versa, so that the corresponding paper pulp roller 202 is close to the lower paper pulp roller 202, so that the distance between the paper pulp rollers 202 is adjusted.

[0033] The working principle and use process of the present application are as follows: In work, the distance between the paper pulp rollers 202 and the distance between the high-temperature steam roller 203 and the paper pulp roller 202 are calculated according to the thickness of the paper in advance, then the locking bolt 305 is loosened, the first gear 303 at both ends of the high-temperature steam roller 203 is twisted to drive the adjusting threaded rod 302 to rotate, the adjusting threaded rod 302 drives the sliding support block 301 to drive the high-temperature steam roller 203 to move close to the paper pulp roller 202, then the double-head cylinder 401 is started, all the double-head cylinders 401 are elongated at the same time, the double-head cylinder 401 pushes the support sliding block 403 to move apart along the limiting sliding groove 402, the support sliding block 403 synchronously drives one end of the support rod 404 to move, so that the support rod 404 is turned over at the hinge point of the support base 405 to make the support rod 404 turn over and push the movable support plate 201 to move upward, the movable support plate 201 drives the paper pulp roller 202 to move away from each other, then the paper is placed between the paper pulp rollers 202 and the high-temperature steam roller 203 in sequence, and the paper is placed.
