Description

Technical Field

[0001] The present invention belongs to the technical field of paper winding, and more specifically, it is a winding control device for a paper embossing machine. Background Art

[0002] Paper embossing is a technology for processing paper through physical means. The original paper is passed between metal rollers engraved with patterns, causing plastic deformation of the original paper, thereby presenting concave and convex patterns on the paper surface that are the same as the metal roller surface, forming embossed paper with three-dimensional beauty and unique texture.

[0003] After paper embossing, winding is required. During the winding process, it is inevitable that the paper will wrinkle towards the middle. Therefore, it is necessary to flatten the paper towards both sides. There are also flattening devices in the prior art, but most of them use mechanical contact to flatten the paper. Since the paper is easily damaged, especially for thinner paper, it is more likely to be damaged, so the mechanical contact method is not applicable.

[0004] In view of this, the present invention proposes a winding control device for a paper embossing machine to solve the above technical problems. Summary of the Invention

[0005] In order to make up for the deficiencies of the prior art, the present invention can blow both sides of the paper to both sides through air flow to flatten the paper and reduce the generation of wrinkles. The present invention provides a winding control device for a paper embossing machine.

[0006] The technical solution adopted by the present invention to solve its technical problems is: a winding control device for a paper embossing machine, including: a chassis, on both ends of the chassis, a guiding roller and a winding roller are respectively fixedly installed; the winding control device for the paper embossing machine further includes: a flattening unit. A flattening unit is arranged on the chassis between the guiding roller and the winding roller. The flattening unit can blow both sides of the paper to both sides through air flow to flatten the paper and reduce the generation of wrinkles. By blowing with air flow instead of mechanical contact flattening, the possibility of paper damage is reduced.

[0007] Among them, the guiding roller is used for guiding, and the winding roller is used for winding. The paper is guided by the guiding roller and wound around the winding roller.

[0008] Preferably, the flattening unit includes: fixed piles, fixed piles are fixedly installed at positions near both ends on both sides of the chassis, each of the fixed piles is fixedly connected to two No. 1 cylinders in the vertical direction, each of the No. 1 cylinders is slidably connected to a No. 1 rod body, and the end of each No. 1 rod body is fixedly connected to a connecting block; an air blowing pipe, all of the No. 1 cylinders correspond one to one in height, and all of the No. 1 cylinders point to the central position of the chassis, and an air blowing pipe is fixedly connected between two connecting blocks of the same height and located on the same side of the chassis, and each of the air blowing pipes is evenly provided with a number of nozzles, and the nozzles on the two air blowing pipes located on the same side of the chassis jointly point to the middle part of the two air blowing pipes. , and is arranged biased towards the outside of the chassis; an air pump, a No. 1 spring is fixedly connected between one end of the interior of the No. 1 cylinder body and the end of the No. 1 rod body, a No. 1 cavity is provided inside the No. 1 rod body and the connecting block, the No. 1 cavity is communicated with the interior of the No. 1 cylinder body, the interior of the blowing pipe is communicated with the No. 1 cavity, the end of the No. 1 rod body is located on both sides of the No. 1 cavity and is slidably connected with a blocking block, the interior of the No. 1 rod body and the corresponding blocking block are fixedly connected with an No. 1 electromagnet, a No. 2 spring is fixedly connected between the blocking block and the corresponding No. 1 electromagnet, the No. 1 electromagnet can attract the blocking block, and the side of the fixed pile is fixedly connected with an air pump corresponding to the position of each No. 1 cylinder body, and each of the air pumps is communicated with the corresponding No. 1 cylinder body.

[0009] Preferably, the amount of current flowing into each of the first electromagnets can be controlled;

[0010] When the paper needs to be flattened, the air pump supplies air. In the initial state, the No. 1 electromagnet is not energized, and the blocking block blocks the No. 1 cavity, so that the airflow does not enter the No. 1 cavity. At this time, the airflow enters the No. 1 cylinder, pushing the No. 1 rod to extend, and the No. 1 spring is compressed, pushing the air blow pipe to the center of the paper. The nozzle does not spray air during the above process. Subsequently, the No. 1 electromagnet is energized, and the airflow enters the No. 1 cavity, enters the air blow pipe, and is ejected from the nozzle. Under the push of the No. 1 spring, the No. 1 rod retracts, that is, the nozzle sprays air to blow the paper and push the paper to both sides. The amount of power supplied to the No. 1 electromagnet can be controlled. When the No. 1 electromagnet is energized, the power is gradually increased. That is, chamber No. 1 is slowly connected, and cooperates with spring No. 1, so that rod No. 1 slowly retracts when it retracts, thereby increasing the blowing time of the nozzle and improving the stroking effect; therefore, in the above process, when rod No. 1 is extended, the nozzle does not blow air and does not mess up the paper; when rod No. 1 retracts, it blows air to stroke the paper to both sides; the maximum extension and shortening of rod No. 1 can be preset, that is, the starting time of the air pump or the blocking time of the blocking block can be controlled, and the retraction speed of rod No. 1 can also be preset, that is, the growth rate of the power supply of electromagnet No. 1 can be controlled to meet the needs of paper of different specifications and different degrees of stroking effects.

[0011] Preferably, a first bent pipe is fixedly connected to the end of all the first rod bodies located on the upper side, the first bent pipe is fixedly connected to a first blowing pipe, a second bent pipe is fixedly connected to the end of all the first rod bodies located on the lower side, the second bent pipe is fixedly connected to a detection cylinder, a vertical groove is provided at the top of the detection cylinder, a pressure sensor is fixedly connected to the bottom of the vertical groove, the first blowing pipe and the detection cylinder are vertical in position and the blowing port of the first blowing pipe faces the corresponding vertical groove, and the inside of the first bent pipe is hollow to communicate the first blowing pipe with the first cavity.

[0012] Preferably, a diversion block is fixedly connected to the end of the first rod body, and a through groove with a trapezoidal cross-sectional shape is provided at the central part of the diversion block;

[0013] When the air flow enters the first cavity, the air flow will also enter the first bent pipe and be blown out from the first blowing pipe. Within the width range of the paper, if the paper is not wrinkled, when the first blowing pipe passes through the paper, the gas blown out by the first blowing pipe is sprayed on the paper. If the paper is wrinkled, within the stroke range of the first blowing pipe, the gas sprayed out by the first blowing pipe will enter the vertical groove in the detection cylinder and be sprayed on the pressure sensor. The pressure sensor will detect the blowing force, thereby realizing the function of detecting wrinkles. At this time, the winding speed of the winding roller can be slowed down or the first rod body stops retracting or slows down retracting, so as to increase the time for the air flow to smooth, and reduce wrinkles; the maximum stroke of the first blowing pipe is the width of the paper.

[0014] Preferably, an annular block is slidably connected inside the blowing pipe, the nozzles are all fixed on the annular block, and the nozzles can expose outside the blowing pipe; a second electromagnet is fixedly connected to the inner wall of the blowing pipe, a first block is fixedly connected to the end of the annular block, and a third spring is fixedly connected between the second electromagnet and the first block. The second electromagnet can attract the first block and make the nozzles rotate towards the outside of the chassis.

[0015] Preferably, a first conductor and a resistance block are fixedly installed on the upper and lower inner walls of the first cylinder body, a conductive block is provided at the end of the first rod body, the first conductor, the resistance block, and the conductive block in the first rod body are jointly connected in series to the control circuit of the second electromagnet, and when the first rod body retracts, the current in the second electromagnet increases;

[0016] When the first rod body retracts, the resistance connected to the control circuit of the second electromagnet decreases, so the current in the second electromagnet increases, gradually attracting the first block and making the nozzles rotate towards the outside of the chassis. Therefore, when the first rod body retracts and the nozzles blow air to smooth the paper, the nozzles rotate. This action is equivalent to blowing air from the middle of the paper to the edge of the paper. The closer to the edge of the paper, the more the paper is blown towards both sides; the smoothing efficiency is improved; similarly, when the first rod body extends, the nozzles reset.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. A winding control device for a paper embossing machine according to the present invention is provided with a flattening unit on the chassis and located between the guiding roller and the winding roller. The flattening unit can blow the two sides of the paper to both sides by air flow to flatten the paper, reduce the generation of wrinkles, and replace mechanical contact flattening with air flow blowing, reducing the possibility of paper breakage.

[0019] 2. When the paper needs to be flattened in the winding control device for a paper embossing machine according to the present invention, the air pump supplies air. In the initial state, the first electromagnet is not energized, the blocking block blocks the first cavity, and the air flow does not enter the first cavity. At this time, the air flow enters the first cylinder body, pushes the first rod body to extend, and the first spring is compressed, pushing the blowing pipe to the central part of the paper. During the above process, the nozzle does not spray air. Subsequently, the first electromagnet is energized, the air flow enters the first cavity, enters the blowing pipe and sprays out from the nozzle. Under the push of the first spring, the first rod body retracts, that is, the nozzle sprays air to blow the paper and smooth the paper to both sides. The energization amount of the first electromagnet can be controlled. When the first electromagnet is energized, the energization amount is gradually increased, that is, the first cavity is slowly connected. Cooperating with the first spring, when the first rod body retracts, it retracts slowly, thereby increasing the blowing time of the nozzle and improving the smoothing effect.

Specific embodiments

[0031] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0032] As Figure 1 , Figure 2 shown, a winding control device for a paper embossing machine according to the present invention includes: a chassis 1, and a guiding roller 11 and a winding roller 12 are respectively fixedly installed at both ends of the chassis 1; the winding control device for a paper embossing machine further includes: a flattening unit 2, and a flattening unit 2 is arranged on the chassis 1 and between the guiding roller 11 and the winding roller 12. The flattening unit 2 can blow both sides of the paper to both sides through air flow to flatten the paper and reduce the generation of wrinkles.

[0033] During operation, after the paper is embossed, it needs to be wound. During the winding process, it is inevitable that the paper will wrinkle towards the middle. Therefore, it is necessary to flatten the paper to both sides. In the prior art, there are also flattening devices, but most of them use mechanical contact methods for flattening. Since the paper is easily damaged, especially for thinner paper, it is more likely to be damaged. Therefore, the mechanical contact method is not applicable; thus, a flattening unit 2 is arranged on the chassis 1 and between the guiding roller 11 and the winding roller 12. The flattening unit 2 can blow both sides of the paper to both sides through air flow to flatten the paper and reduce the generation of wrinkles. By using air flow blowing instead of mechanical contact flattening, the possibility of paper damage is reduced.

[0034] Among them, the guiding roller 11 is used for guiding, and the winding roller 12 is used for winding. The paper is guided by the guiding roller 11 and wound around the winding roller 12.

[0035] As a specific embodiment of the present invention, as Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6As shown in the figure, the flattening unit 2 includes: fixing piles 21, which are fixedly installed at positions near both ends on both sides of the chassis 1. Two first cylinders 22 are fixedly connected vertically on each fixing pile 21. A first rod 23 is slidably connected inside each first cylinder 22, and a connecting block 24 is fixedly connected to the end of each first rod 23; an air blowing pipe 25. All the first cylinders 22 correspond to each other in height, and all the first cylinders 22 point to the central position of the chassis 1. An air blowing pipe 25 is fixedly connected between two connecting blocks 24 of the same height and on the same side of the chassis 1. A plurality of nozzles 26 are evenly arranged on each air blowing pipe 25. The nozzles 26 on two air blowing pipes 25 on the same side of the chassis 1 jointly point to the middle part between these two air blowing pipes 25 and are arranged to deviate towards the outside of the chassis 1; an air pump 27. A first spring 28 is fixedly connected between one end inside the first cylinder 22 and the end of the first rod 23. A first cavity 29 is arranged inside the first rod 23 and the connecting block 24. The first cavity 29 is communicated with the inside of the first cylinder 22. The inside of the air blowing pipe 25 is communicated with the first cavity 29. A shielding block 3 is slidably connected to both sides of the first cavity 29 at the end of the first rod 23. A first electromagnet 31 is fixedly connected to the part of the first rod 23 corresponding to the shielding block 3. A second spring 32 is fixedly connected between the shielding block 3 and the corresponding first electromagnet 31. The first electromagnet 31 can attract the shielding block 3. An air pump 27 is fixedly connected to the side of the fixing pile 21 corresponding to each first cylinder 22. Each air pump 27 is communicated with the inside of the corresponding first cylinder 22;

[0036] The power consumption of each first electromagnet 31 can be controlled;

[0037] During operation, when it is necessary to flatten the paper, the air pump 27 supplies air. In the initial state, the first electromagnet 31 is not energized, and the blocking block 3 blocks the first chamber 29, so that the air flow does not enter the first chamber 29. At this time, the air flow enters the first cylinder body 22, pushes the first rod body 23 to extend, compresses the first spring 28, and pushes the blowing pipe 25 to the central part of the paper. During the above process, the nozzle 26 does not spray air. Subsequently, the first electromagnet 31 is energized, the air flow enters the first chamber 29, enters the blowing pipe 25 and sprays out from the nozzle 26. Under the push of the first spring 28, the first rod body 23 retracts, that is, the nozzle 26 sprays air to blow the paper and move the paper to both sides. The energization amount of the first electromagnet 31 can be controlled. When the first electromagnet 31 is energized, the energization amount is gradually increased, that is, the first chamber 29 is slowly connected. Cooperating with the first spring 28, when the first rod body 23 retracts, it retracts slowly, thereby increasing the blowing time of the nozzle 26 and improving the moving effect. Therefore, during the above process, when the first rod body 23 extends, the nozzle 26 does not blow air and does not blow the paper disorderly. When the first rod body 23 retracts, it blows air and moves the paper to both sides. The maximum amplitudes of the extension and shortening of the first rod body 23 can be preset, that is, the starting time of the air pump 27 or the blocking time of the blocking block 3 is controlled. The retraction speed of the first rod body 23 can also be preset, that is, the growth speed of the energization amount of the first electromagnet 31 is controlled to meet different specifications of paper and different degrees of moving effects.

[0038] As a specific embodiment of the present invention, as Figure 3 、 Figure 7 shown, a first bent pipe 4 is fixedly connected to the end of all the first rod bodies 23 located on the upper side. The first bent pipe 4 is fixedly connected with a first blowing pipe 41. A second bent pipe 42 is fixedly connected to the end of all the first rod bodies 23 located on the lower side. The second bent pipe 42 is fixedly connected with a detection cylinder 43. A vertical groove 44 is provided at the top of the detection cylinder 43. A pressure sensor 45 is fixedly connected to the bottom of the vertical groove 44. The first blowing pipe 41 and the detection cylinder 43 are vertical in position and the blowing port of the first blowing pipe 41 is directly opposite to the corresponding vertical groove 44. The inside of the first bent pipe 4 is hollow to connect the first blowing pipe 41 and the first chamber 29;

[0039] As Figure 5 、 Figure 6 shown, a diversion block 5 is fixedly connected to the end of the first rod body 23. The central part of the diversion block 5 is a through groove with a trapezoidal cross-sectional shape;

[0040] During operation, when the air flow enters the first chamber 29, the air flow also enters the first elbow pipe 4 and is blown out from the first blowing pipe 41. Within the width range of the paper, if the paper is not wrinkled, when the first blowing pipe 41 passes over the paper, the gas blown out by the first blowing pipe 41 is sprayed onto the paper. If the paper is wrinkled, within the travel range of the first blowing pipe 41, the gas blown out by the first blowing pipe 41 will enter the vertical groove 44 in the detection cylinder 43 and be sprayed onto the pressure sensor 45. The pressure sensor 45 will detect the blowing force, thereby realizing the function of detecting wrinkles. At this time, the winding speed of the winding roller 12 can be slowed down or the first rod body 23 can stop retracting or slow down retracting, so as to increase the time for the air flow to smooth the paper and reduce wrinkles; the maximum travel of the first blowing pipe 41 is the width of the paper.

[0041] As a specific embodiment of the present invention, as Figure 8 , Figure 9 shown, a ring block 6 is slidably connected inside the blowing pipe 25, and the nozzles 26 are all fixed on the ring block 6, and the nozzles 26 can be exposed outside the blowing pipe 25; a second electromagnet 61 is fixedly connected to the inner wall of the blowing pipe 25, a first block 62 is fixedly connected to the end of the ring block 6, and a third spring 63 is fixedly connected between the second electromagnet 61 and the first block 62. The second electromagnet 61 can attract the first block 62 and make the nozzles 26 rotate outward relative to the chassis 1;

[0042] As Figure 5 shown, a first conductor 7 and a resistance block 71 are fixedly installed on the upper and lower inner walls of the first cylinder body 22. A conductive block is arranged at the end of the first rod body 23. The first conductor 7, the resistance block 71, and the conductive block in the first rod body 23 are commonly connected in series to the control circuit of the second electromagnet 61. And when the first rod body 23 retracts, the current in the second electromagnet 61 increases;

[0043] During operation, when the first rod body 23 retracts, the resistance connected to the control circuit of the second electromagnet 61 decreases, so the current in the second electromagnet 61 increases, gradually attracting the first block 62 and making the nozzles 26 rotate outward relative to the chassis 1. Therefore, when the first rod body 23 retracts and the nozzles 26 blow air to smooth the paper, the nozzles 26 rotate. This action is equivalent to blowing air from the middle of the paper to the edges of the paper. The closer to the edges of the paper, the more the paper is blown to both sides; the smoothing efficiency is improved. Similarly, when the first rod body 23 extends, the nozzles 26 reset.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the above embodiments, those of ordinary skill in the art should understand that: still can modify the specific embodiments of the present invention or make equivalent substitutions, and any modification or equivalent substitution that does not depart from the spirit and scope of the present invention should be covered within the protection scope of the claims of the present invention.
