Description

Technical Field

[0001] This utility model belongs to the field of sizing agent coating rollers, specifically relating to a sizing agent coating roller resistant to acid media penetration. Background Technology

[0002] To improve the anti-corrosion protection, aesthetics, and functionality of the substrate, it is often necessary to apply specific coatings or adhesives to the substrate surface using coating rollers. In the paperboard processing, to impart properties such as ink resistance, water resistance, emulsion resistance, and corrosion resistance to the paperboard, and to improve its smoothness, strength, and service life, it is often necessary to apply sizing agents with excellent waterproof properties and resistance to acid penetration to the surface of the paperboard.

[0003] Currently, during the coating process, the coating roller needs to be installed on the coating device. Since the coating roller needs to rotate, its two ends are often fixedly connected to the rotating shaft, which is movably inserted into the support plate of the coating device. If the coating roller needs to be replaced, the support plate of the coating device needs to be moved. The support plate of the coating device is large in size, and its movement requires a lot of space.

[0004] Therefore, to address the problem that the existing coating rollers often require moving one side of the coating device during installation, resulting in a large amount of space being occupied, an acid-resistant sizing agent coating roller with a sliding connection on one side of the rotating shaft can be designed. Utility Model Content

[0005] To overcome the problem that existing coating roller installations often require moving one side of the coating unit, resulting in a large amount of space being occupied.

[0006] The technical solution of this utility model is as follows: an acid-resistant sizing agent coating roller, including a coating roller body; and a movable rotating shaft. A fixed rotating shaft is fixedly connected to the right side of the coating roller body, and a movable rotating shaft is provided on the left side of the coating roller body. A receiving groove is opened on the left side of the coating roller body, and the movable rotating shaft is movably connected to the receiving groove. Four sliding grooves arranged in a ring are opened in the receiving groove. A slider fixedly connected to the outside of the movable rotating shaft is movably connected in the sliding groove. An installation ring is fixedly connected to the side of the fixed rotating shaft opposite to the movable rotating shaft.

[0007] Preferably, by pulling the movable shaft, it is pulled out of the receiving groove, causing the slider to move in the chute until the movable shaft passes through the support plate. The slider is in close contact with the inner wall of the chute to achieve limiting and linkage. When the movable shaft is rotated, due to the restriction of the chute and the slider, the coating roller body sleeved on the outside of the movable shaft will rotate together with the movable shaft. When disassembly is required, the movable shaft is pushed into the receiving groove to shorten it and remove it from the installation range of the support plate.

[0008] Preferably, a support platform is provided below the coating roller body, and two opposing support plates are fixedly connected to the support platform. The fixed rotating shaft is movably inserted into the support plate on the left, and the movable rotating shaft is movably inserted into the support plate on the right.

[0009] Preferably, a motor is installed on the opposite side of the support plate, and a connecting ring is fixedly connected to the output end of the motor on the opposite side. The connecting platform is close to the outside of the mounting ring, and a fixing bolt is inserted into the connecting ring and the mounting ring.

[0010] Preferably, the motor is fixedly connected to a No. 1 mounting base that is close to the outside of the support plate, and the No. 1 mounting base has a No. 1 anchoring hole that penetrates through the No. 1 mounting base.

[0011] Preferably, a left and right opposing limiting plate is sleeved under the coating roller body, and an installation rod that is tightly attached to the support plate is fixedly connected to the opposite side of the limiting plate.

[0012] Preferably, a second mounting base is fixedly connected to the opposite side of the mounting rod, which is close to the inner side of the support plate, and the second mounting base has a second anchoring hole.

[0013] Preferably, a scraper is installed between the two limiting plates on the outside of the coating roller body, and the left and right sides of the scraper are fixedly connected to the No. 3 mounting base closely attached to the rear side of the limiting plate.

[0014] The beneficial effects of this utility model are:

[0015] By replacing the fixed rotating shaft connected to one side of the coating roller body with a movable rotating shaft, the movable rotating shaft slides left and right within a receiving groove opened in the coating roller body. The sliding length is limited by an internal sliding groove and a slider fixedly connected to the movable rotating shaft. At the same time, the sliding groove and the slider are used to link the movable rotating shaft with the coating roller body. When the movable rotating shaft rotates, the coating roller body will also rotate together. This design allows the exposed length of the movable rotating shaft to be changed without changing the position of the support plate when installing the coating roller body. The movable rotating shaft side of the coating roller body can be detached from the support plate, realizing the disassembly and assembly of the coating roller body. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-6This utility model provides an embodiment of an acid-resistant sizing agent coating roller, comprising a coating roller body 1 and a movable rotating shaft 2. A fixed rotating shaft 3 is fixedly connected to the right side of the coating roller body 1, and the movable rotating shaft 2 is disposed on the left side of the coating roller body 1. A receiving groove 4 is formed on the left side of the coating roller body 1, and the movable rotating shaft 2 is movably connected to the receiving groove 4. Four sliding grooves 5 are arranged in a ring within the receiving groove 4, and sliders 6, which are fixedly connected to the outside of the movable rotating shaft 2, are movably connected to the sliding grooves 5. The fixed rotating shaft 3 and the movable rotating shaft 2 are connected to the sliding grooves 5. A mounting ring 7 is fixedly connected to one side of the movable shaft 2. By pulling the movable shaft 2, it is pulled out of the receiving groove 4, causing the slider 6 to move within the slide groove 5 until the movable shaft 2 passes through the support plate 9. The slider 6 is tightly pressed against the inner wall of the slide groove 5 to achieve limiting and linkage. When the movable shaft 2 is rotated, due to the restriction of the slide groove 5 and the slider 6, the coating roller body 1, which is sleeved on the outside of the movable shaft 2, will rotate together with the movable shaft 2. When disassembly is required, the movable shaft 2 is pushed into the receiving groove 4 to shorten it and remove it from the installation range of the support plate 9. A support platform 8 is provided below the coating roller body 1. Two opposing support plates 9 are fixedly connected to the support platform 8. A fixed rotating shaft 3 is movably inserted into the left support plate 9, and a movable rotating shaft 2 is movably inserted into the right support plate 9. The support platform 8 provides support for the support plates 9, which in turn provide support for the coating roller body 1 in the middle. A motor 10 is installed on the opposite side of the support plates 9. A connecting ring 11 is fixedly connected to the opposite side of the output end of the motor 10. The connecting ring 11 is close to the outside of the mounting ring 7. A fixing bolt is inserted into the mounting ring 7. The fixed rotating shaft 3 and the movable rotating shaft 2 can be connected to the output end of the corresponding motor 10 through the connecting ring 11 and the mounting ring 7. The motor 10 provides power for its rotation. The outer side of the motor 10 is fixedly connected to the first mounting seat 12, which is close to the outer side of the support plate 9. The first mounting seat 12 has a first anchoring hole 13 that passes through the first mounting seat 12. The first mounting seat 12 and the motor 10 fixedly connected to the first mounting seat 12 are fixed to the support plate 9 by the anchor through the first anchoring hole 13.

[0025] Please see Figures 1-6In this embodiment, a left and right opposing limiting plate 14 is sleeved below the coating roller body 1. A mounting rod 15, tightly attached to the support plate 9, is fixedly connected to the opposite side of the limiting plate 14. The limiting plates 14 have different models, and the lengths of the mounting rods 15 differ between models. The appropriate limiting plate 14 can be selected for installation according to the width of the cardboard being processed, thus limiting the coating range of the coating roller body 1 and avoiding waste of the sizing agent used to resist acid penetration. A second mounting seat 16, tightly attached to the inner side of the support plate 9, is fixedly connected to the opposite side of the mounting rod 15. A second anchoring hole 17 is provided on the second mounting seat 16. The rod passes through the second anchoring hole 17... The anchor of 7 fixes the second mounting base 16 and the limiting plate 14 connected to the second mounting base 16 to the support plate 9. A scraper 18 is installed between the two limiting plates 14 on the outside of the coating roller body 1. The left and right sides of the scraper 18 are fixedly connected to the third mounting base 19 that is close to the back of the limiting plate 14. The scraper 18 can scrape the sizing agent on the surface of the coating roller to make it evenly coated during the coating process. At the same time, the scraper 18 has different models and can be adjusted according to the distance between the limiting plates 14. After the processing is completed, the surface of the coating roller body 1 can be cleaned by the scraper 18 that is close to the coating roller body 1.

[0026] During operation, the worker first passes the anchor through the first anchor hole 13 on the first mounting base 12 and installs the motor 10 on the outside of the support plate 9. Then, the coating roller body 1 is moved to the support platform 8. Then, one side of the fixed rotating shaft 3 is inserted into the support plate 9, and its mounting ring 7 is fixed to the connecting ring 11 fixedly connected to the output end of the motor 10 on the same side by the fixing bolt. Then, the movable rotating shaft 2 on the other side is pushed. The movable rotating shaft 2 moves to the left from the storage groove 4, while driving the slider 6 to move to the left in the slide groove 5 until the movable rotating shaft 2 is inserted into the support plate 9 on the other side and connected to the motor 10 on the same side.

[0027] Select the appropriate model of limiting plate 14 and scraper 18 according to the required width of the cardboard to be processed. Fit the limiting plate 14 onto the outside of the coating roller body 1. Then, pass the anchor through the second anchor hole 17 and fix it to the surface of the support plate 9. Install the scraper 18 between the two limiting plates 14 and apply the sizing agent to the surface of the coating roller. Start the motor 10 and make it rotate slowly so that the scraper 18 can spread the sizing agent evenly.

[0028] The conveyor belt feeds the cardboard in, and the motor 10 drives the fixed rotating shaft 3 and the movable rotating shaft 2 to rotate. Under the restriction of the chute 5 and the slider 6, the coating roller body 1 rotates together with the fixed rotating shaft 3 and the movable rotating shaft 2, and the sizing agent on the surface is evenly coated onto the surface of the cardboard. After the processing is completed, the scraper 18 can be removed and replaced with another type of scraper 18, which is then pressed tightly against the surface of the coating roller body 1. The motor 10 is then started, and the scraper 18 scrapes off the remaining coating, achieving a partial cleaning effect.

[0029] Through the above steps, the fixed rotating shaft 3 connected to one side of the coating roller body 1 is replaced with a movable rotating shaft 2. The movable rotating shaft 2 slides left and right within the receiving groove 4 opened inside the coating roller body 1. The sliding length is limited by the internal sliding groove 5 and the slider 6 fixedly connected to the movable rotating shaft 2. At the same time, the sliding groove 5 and the slider 6 are used to realize the linkage between the movable rotating shaft 2 and the coating roller body 1. When the movable rotating shaft 2 rotates, the coating roller body 1 will also rotate together. With this design, when installing the coating roller body 1, the exposed length of the movable rotating shaft 2 can be changed without changing the position of the support plate 9. The movable rotating shaft 2 side of the coating roller body 1 can be detached from the support plate 9, realizing the disassembly and assembly of the coating roller body 1. This solves the problem that when installing existing coating rollers, it is often necessary to move one side of the coating device, which requires a lot of space.
