Description

Technical Field

[0001] This utility model relates to the field of dyed paper manufacturing technology, specifically to a multi-directional adjustable dyed paper roller pressing mechanism. Background Technology

[0002] Multi-directional adjustable dyeing paper roller pressing mechanism is a type of mechanism developed to address the upgrading needs of the paper dyeing industry for dyeing quality, production efficiency, and adaptability, as well as to solve many defects in the structure and function of traditional dyeing paper roller pressing equipment. However, in actual use, due to the different thicknesses and types of paper being dyed, the water absorption of the paper also varies. When dyeing paper, the height of the dyeing rollers in common dyeing paper roller pressing mechanisms is mostly uniform and cannot be adjusted. This means that regardless of the different thicknesses and water absorption properties of the paper, it can only absorb dye at a fixed height. This can easily lead to the paper absorbing too much dye, resulting in incomplete dye removal during subsequent roller pressing or easy paper breakage. It is extremely inconvenient to use and affects subsequent processing and drying. Utility Model Content

[0003] The purpose of this invention is to provide a multi-directional adjustable dyeing paper roller pressing mechanism to solve the problem mentioned in the background art that the inability to adjust the depth of paper immersion in dye according to the paper material and thickness affects subsequent processing.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-directional adjustable dyeing paper roller pressing mechanism, comprising a machine body, guide rollers fixedly installed inside the machine body, a dyeing tank fixedly installed inside the machine body and located below the guide rollers, a main roller shaft rotatably installed on the side of the machine body away from the dyeing tank and the height of the main roller shaft being higher than the height of the dyeing tank, swing arms rotatably installed on the outer surfaces of both sides of the machine body, and an impregnation pressing roller fixedly installed on the outer surface of the swing arm shaft and located above the dyeing tank, a limit screw threadedly installed on one side of the machine body and one end of the limit screw being in contact with the outer surface of the swing arm, and a monitoring thread mechanism provided between the machine body and the swing arm.

[0005] Preferably, the monitoring thread mechanism includes: a limiting screw, a weighing sensor is fixedly installed on the side of the machine body near the limiting screw, and a first screw is fixedly installed on the other end of the weighing sensor. A first sleeve is threaded on the outer surface of the first screw, and a second screw is threaded on the inner surface of the first sleeve. The thread direction of the second screw is opposite to that of the first screw. A first locking nut is threaded on the outer surface of the first screw, and the outer surface of the first locking nut is in contact with the outer surface of the first sleeve. The outer surface of the second screw is in contact with the outer surface of the swing arm.

[0006] By adopting the above technical solution, the length and distance between the first screw and the second screw can be adjusted by rotating the first sleeve, and fixed by locking the first locking nut. This allows the first and second screws to support the swing arm and can be adjusted according to the depth of the dyeing press roller immersed in the dyeing tank. Furthermore, the load cell connected to the first screw can monitor the tension of the paper as it passes through the dyeing press roller, allowing for real-time monitoring of the overall tension of the paper as it passes through, thereby controlling the rotation speed of the main roller shaft. In the event of paper breakage, the load cell can detect the breakage and immediately stop the main roller shaft, alerting employees and greatly improving the convenience of use.

[0007] Preferably, side silicone strips are inserted and installed on the outer surfaces of both sides of the dyeing tank, and the outer surfaces of the side silicone strips are tightly fitted to the two sides inside the machine body.

[0008] By adopting the above technical solution, the side silicone strip can effectively prevent the possibility of leakage between the dyeing tank and the machine body after the dye is squeezed out by the main roller and driven roller, and the side silicone strip can be easily installed and replaced on both sides of the machine body.

[0009] Preferably, the end of the dyeing tank away from the dyeing press roller is designed to be inclined, and the end of the dyeing tank near the dyeing press roller is provided with a solenoid valve.

[0010] By adopting the above technical solution, the inclined design of the dyeing tank allows the side near the dyeing press roller to be deeper, enabling the dyeing press roller to better extend into the interior of the dyeing tank and more conveniently gather the dye, so that the dye can be more fully utilized, and the solenoid valve can be opened to rinse the dyeing tank when changing the dye.

[0011] Preferably, a slider is slidably mounted on the end of the machine body away from the guide roller, and a driven roller shaft is rotatably mounted between the sliders. The outer surface of the driven roller shaft is in contact with the outer surface of the main roller shaft. The slider is engaged with the machine body. A groove is provided on the outer surface of the machine body near the slider, and a spring is provided between the slider and the groove of the machine body. A threaded adjustment mechanism is provided between the machine body and the slider.

[0012] By adopting the above technical solution, the spring can effectively push the slider and the driven roller to move, making it more convenient to clean the paper material wrapped on the main roller or the driven roller. It also makes it easy to pass the paper between the main roller and the driven roller after cutting the material, greatly improving the convenience of use.

[0013] Preferably, the threaded adjustment mechanism includes: a pressure plate frame, which is fixedly installed on both sides of the machine body. An electric push rod is fixedly installed on the outer surface of the pressure plate frame, and the output end of the electric push rod passes through the pressure plate frame. A third screw is threadedly installed on the outer surface of the slider, and a second sleeve is threadedly installed on the outer surface of the third screw. The second sleeve is threadedly connected to the output end of the electric push rod, and the thread directions of the electric push rod and the third screw are opposite. A second locking nut is threadedly installed on the outer surface of the output end of the electric push rod, and the outer surface of the second locking nut is in contact with the outer surface of the second sleeve.

[0014] By adopting the above technical solution, the distance between the third screw and the electric push rod can be adjusted by rotating the second sleeve, and it can be locked by the second locking nut. This allows the position of the slider inside the machine body to be adjusted, thereby adjusting the clamping force between the main roller shaft and the driven roller shaft. This allows the clamping force to be adjusted when dealing with paper of different thicknesses, enabling the paper to better remove excess dye and better combine with the dye, greatly improving the convenience of use and the dyeing effect of the paper.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the multi-directional adjustable dyeing paper roller pressing mechanism:

[0016] 1. When in use, simply rotate and lock the limiting screw on one side of the machine body. The weight of the swing arm and the dyeing press roller itself will allow the swing arm to be pressed against the limiting screw, so that the depth of the dyeing press roller into the dyeing tank can be adjusted. This allows the roller pressing mechanism to adjust the depth of the dyeing press roller according to different thicknesses and materials, and allows the roller pressing mechanism to be flexibly adjusted when facing paper of different thicknesses, greatly improving the convenience of adjusting the dyeing press roller during use.

[0017] 2. When in use, simply rotating the first sleeve adjusts the distance between the first and second screws, and tightening the first locking nut fixes the lengths of the first and second screws, allowing them to contact the swing arm for support. When the roller pressing mechanism passes through the dyeing press roller and operates, the swing arm can bear force and squeeze the first and second screws, allowing the load cell to monitor the tension of the paper movement in real time, thereby adjusting the rotation speed of the main roller shaft. The load cell can also detect when the paper breaks, alerting the operator to material breakage and greatly improving ease of use.

[0018] 3. By turning the second sleeve, the distance between the electric push rod and the third screw can be adjusted, and it can be locked by the second locking nut. This allows the position of the slider inside the machine body to be adjusted, and the clamping force between the main roller shaft and the driven roller shaft to be adjusted. This allows for flexible adjustment when dealing with paper of different materials and thicknesses. Furthermore, the retraction of the electric push rod facilitates the cleaning and feeding of tangled material, greatly improving the convenience of use and the quality of paper rolling.

[0026] 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.

[0027] Please see Figure 1-6This utility model provides a technical solution: a multi-directional adjustable dyeing paper roller pressing mechanism, including a machine body 1. Guide rollers 5 are fixedly installed inside the machine body 1. A dyeing tank 2 is fixedly installed inside the machine body 1, and the dyeing tank 2 is located below the guide rollers 5. A main roller shaft 3 is rotatably installed on the side of the machine body 1 away from the dyeing tank 2, and the height of the main roller shaft 3 is higher than the height of the dyeing tank 2. Swing arm rods 7 are rotatably installed on the outer surfaces of both sides of the machine body 1, and an impregnation pressing roller 6 is fixedly installed on the outer surface of the rotating shaft of the swing arm rod 7, and the impregnation pressing roller 6 is located above the dyeing tank 2. A limit screw 8 is threadedly installed on one side of the machine body 1, and one end of the limit screw 8 is in contact with the outer surface of the swing arm rod 7. A monitoring thread mechanism is provided between the body 1 and the swing arm 7. The monitoring thread mechanism includes: a limit screw 8, a weighing sensor 9 is fixedly installed on the side of the body 1 near the limit screw 8, and a first screw 10 is fixedly installed on the other end of the weighing sensor 9. A first sleeve 11 is threaded on the outer surface of the first screw 10, and a second screw 12 is threaded on the inner surface of the first sleeve 11. The thread direction of the second screw 12 is opposite to that of the first screw 10. A first locking nut 13 is threaded on the outer surface of the first screw 10, and the outer surface of the first locking nut 13 is in contact with the outer surface of the first sleeve 11. The outer surface of the second screw 12 is in contact with the outer surface of the swing arm 7.

[0028] Firstly, during use, the limiting screw 8 needs to be rotated according to the thickness and material of the paper to be dyed. This allows the limiting screw 8 to move the swing arm 7, enabling the dyeing pressing roller 6 to adjust its depth into the dyeing tank 2 according to its own weight. The distance between the first screw 10 and the second screw 12 can be adjusted by rotating the first sleeve 11, and then locked by the first locking nut 13, so that the second screw 12 contacts the outer surface of the swing arm 7. This allows the paper to contact the dye at the appropriate time and depth when it passes through the dyeing pressing roller 6 under the guidance of the guide roller 5. The tension generated by the squeezing of the swing arm 7 during paper movement can be monitored in real time by the weighing sensor 9, and the speed of the main roller shaft 3 can be adjusted in real time. An alarm can be triggered when the paper breaks. This allows papers of different thicknesses and materials to be better dyed and contacted by the dye, greatly improving the dyeing effect of the paper during roller pressing, and automatically adjusting the paper feeding speed in real time.

[0029] Side silicone strips 4 are inserted and installed on the outer surfaces of both sides of the dyeing tank 2, and the outer surfaces of the side silicone strips 4 are tightly fitted to the two sides inside the machine body 1. The end of the dyeing tank 2 away from the dyeing pressing roller 6 is designed to be inclined, and a solenoid valve 22 is opened at the end of the dyeing tank 2 close to the dyeing pressing roller 6.

[0030] Secondly, the side silicone strip 4 can effectively prevent the splashing of dye when the main roller 3 and driven roller 14 roll the paper, reducing the chance of dye sliding down the inner wall of the machine body 1 and leaking out of the dyeing tank 2, thus reducing dye loss. When changing the color of the paper to be printed, simply open the solenoid valve 22 and release the residual dye for collection. Then the inside of the dyeing tank 2 can be cleaned, greatly reducing dye loss and making cleaning and material change more convenient.

[0031] A slider 15 is slidably mounted on the end of the machine body 1 away from the guide roller 5, and a driven roller shaft 14 is rotatably mounted between the sliders 15. The outer surface of the driven roller shaft 14 is in contact with the outer surface of the main roller shaft 3. The slider 15 is engaged with the machine body 1. A groove is formed on the outer surface of the machine body 1 on the side near the slider 15, and a spring 16 is provided between the slider 15 and the groove of the machine body 1. A threaded adjustment mechanism is provided between the machine body 1 and the slider 15. The threaded adjustment mechanism includes a pressure plate frame 17, which is fixedly mounted on both sides of the machine body 1. An electric push rod 18 is fixedly installed on the outer surface of the slide block 15, and the output end of the electric push rod 18 passes through the pressure plate frame 17. A third screw 19 is threadedly installed on the outer surface of the slide block 15, and a second sleeve 20 is threadedly installed on the outer surface of the third screw 19. The second sleeve 20 is threadedly connected to the output end of the electric push rod 18, and the thread directions of the electric push rod 18 and the third screw 19 are opposite. A second locking nut 21 is threadedly installed on the outer surface of the output end of the electric push rod 18, and the outer surface of the second locking nut 21 is in contact with the outer surface of the second sleeve 20.

[0032] Furthermore, when dealing with paper of different thicknesses, simply rotating the second sleeves 20 on both sides adjusts the distance between the electric push rod 18 and the third screw 19. Then, locking is achieved by the second locking nut 21, allowing the distance between the slider 15 and the pressure plate frame 17 to be adjusted. The use of the spring 16 enables the slider 15 to return to its original position more quickly when the electric push rod 18 retracts, making it more convenient to clean up tangled material and thread it through the paper. At the same time, the clamping force of the main roller shaft 3 and the driven roller shaft 14 can be adjusted more flexibly, allowing paper of different thicknesses to be rolled better, greatly improving the convenience of rolling.

[0033] Working principle: During use, simply rotate the limiting screw 8 according to the material and thickness of the paper and push or release the swing arm 7 to adjust the position of the dyeing press roller 6 in the dyeing tank 2. Then, adjust the second screw 12 so that it can contact the swing arm 7, allowing the weighing sensor 9 to monitor the pressure of the swing arm 7. Then, rotate the second sleeve 20 to adjust the distance between the pressure plate frame 17 and the slider 15, so that the pressure between the main roller shaft 3 and the driven roller shaft 14 can be adjusted to a suitable range. Then, the paper can be passed through the guide roller 5, the dyeing press roller 6, and between the main roller shaft 3 and the driven roller shaft 14. Then, the slider 15 can be pushed out by the electric push rod 18 to clamp the paper. Then, the main roller shaft 3 can be started to feed and squeeze the paper, allowing the paper to pass through the dyeing tank 2 and come into contact with the dye for dyeing. Through the squeezing of the main roller shaft 3 and the driven roller shaft 14, the dye in the paper can be better removed and squeezed out, greatly improving the dyeing effect of the paper, thus completing the dyeing of the paper.

[0034] 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.
