Technical Field
[0001] This utility model relates to the field of steel rollers for coating machines, and in particular to a steel roller for a woven bag coating machine. Background Technology
[0002] Woven bags are packaging materials made of flat plastic yarns. Woven bags are prone to aging during use, so a film material needs to be coated on the surface of the woven bag to enhance its strength, water resistance, and durability, thereby improving its quality and service life. Woven bag coating machines use steel rollers to evenly coat the film material onto the surface of the woven bag.
[0003] Most existing coating machine steel roller devices are equipped with a synchronous pressing steel roller structure. The steel rollers press the film material to evenly spread the coating. During use, the steel rollers are mostly pressed down simultaneously, at the same distance or at a fixed interval to coat the film. However, the synchronous pressing of the coating material can easily cause some dispersion, which leads to a decrease in the effectiveness of the coating machine steel roller device.
[0004] Therefore, in response to the problem that in the existing coating machine steel roller device, the steel rollers are mostly pressed down simultaneously, at the same distance or at a fixed interval to apply the coating, and the simultaneous pressing of the coating material can easily cause some dispersion, resulting in a decrease in the effectiveness of the coating machine steel roller device, a steel roller for woven bag coating machine can be designed.

[0015] This invention relates to a steel roller for a woven bag coating machine. The machine is equipped with a support frame that drives a first steel roller body to press the coating material. Simultaneously, the machine presses a connecting frame, causing a second steel roller body to press down. This causes a rotating frame to rotate the connecting frame around the first steel roller body. The second steel roller body is then rotated via a second rotating joint, further distributing the coating material through the second steel roller body and pressing the coating area to varying degrees. A second support spring then resets the roller, allowing for repeated pressing of the coating area, thus improving the overall coating effect and reducing coating defects. Attached Figure Description

[0023] Please see Figures 1-5 This utility model provides an embodiment: a steel roller for a woven bag coating machine, including a first steel roller body 1; it also includes a support frame 6 and a rotating frame 17. Support frames 6 for pressing are provided at both ends of the first steel roller body 1. A support tube 10 is fixedly connected to one end of the support frame 6, and the rotating frame 17 is rotatably connected to the outside of the support tube 10. A second support spring 18 is installed between the support tube 10 and the rotating frame 17. A connecting frame 19 is rotatably connected to the front end of the rotating frame 17 via a rotating shaft. A limit groove 20 is formed at the upper end of the connecting frame 19, and a limit groove 20 is fixedly connected to the lower end of the connecting frame 19. A second rotating joint 22 is installed on one side of the fixed plate 21 and the connecting frame 19. A second steel roller body 23 for assisting in pressing the coating film is rotatably connected between the two second rotating joints 22. This structure is installed on the coating machine through the support frame 6 so as to drive the first steel roller body 1 to press the coating film. The rotating frame 17 drives the connecting frame 19 to rotate around the first steel roller body 1 and resets it through the second support spring 18. At the same time, it drives the second steel roller body 23 to press down, thereby repeatedly pressing the coating area to improve the overall coating effect. The second steel roller body 23 is rotated through the second rotating joint 22.
[0024] Please see Figures 2-3In this embodiment, a first connecting grid plate 2 is installed on the outer side of the first steel roller body 1. A first rotating joint 3 is fixedly connected to one end of the first connecting grid plate 2. The first steel roller body 1 and the first connecting grid plate 2 are rotatably connected to the support frame 6 through the first rotating joint 3. The first connecting grid plate 2 and the first rotating joint 3 facilitate the rotation of the first steel roller body 1 and allow ventilation. A cooling pipe 4 is installed between the two first connecting grid plates 2. A cooler body 5 is installed at the upper end of the cooling pipe 4. A second connecting grid plate 7 is installed at one end of the support frame 6. The cooling pipe 4 and the cooler body 5 help to reduce the temperature of the first steel roller body 1, and the second connecting grid plate 7 cooperates with the first connecting grid plate 2 to assist ventilation. A support platform 8 is fixedly connected to the front end of the support frame 6. A sliding groove 9 is slidably connected to the front end of the support platform 8. The fixed plate 21 and the support platform 8 are slidably connected through the sliding groove 9. The support platform 8 and the sliding groove 9 support the connecting frame 19.
[0025] Please see Figures 3-5 In this embodiment, a mounting frame 11 is fixedly connected to one end of the support tube 10, and a pump body 12 is fixedly connected to the inner side of the mounting frame 11. The pump body 12 is used to fill the support frame 6 with gas to cooperate with the first connecting grid plate 2 and the second connecting grid plate 7 to quickly discharge cold air, preventing the continuous low temperature from affecting the subsequent coating effect. A positioning rod 13 is fixedly connected to the lower end of the mounting frame 11, and a mounting platform 14 is slidably connected to the outer side of the positioning rod 13. The mounting platform 14 and the positioning rod 13 support the support frame 6 and the first steel roller body 1. A positioning plate 15 is fixedly connected to one end of the mounting platform 14, and a first support spring 16 is installed between the positioning plate 15 and the support frame 6. An mounting rod 24 is slidably connected to the inner side of the limiting groove 20. The first support spring 16 supports the mounting frame 11 and the support frame 6, so that the frame can be reset after pressing the coating. The mounting rod 24 is used to connect to the woven bag coating machine to press the second steel roller body 23.
[0026] In use, firstly, the support frame 6, mounting platform 14 and mounting rod 24 are connected to the woven bag coating machine. Then, the support frame 6 drives the first steel roller body 1 to press the coating. Then, the cooling pipe 4 and the cooler body 5 help to reduce the temperature of the first steel roller body 1, and the second connecting grid plate 7 cooperates with the first connecting grid plate 2 to assist in ventilation. Finally, the support platform 8 and the slide 9 support the connecting frame 19, and the mounting rod 24 presses the connecting frame 19, while the second support spring 18 resets the frame.
[0027] During coating, firstly, the support frame 6 and the first steel roller body 1 are supported by the mounting platform 14 and the positioning rod 13, and the mounting frame 11 and the support frame 6 are supported by the first support spring 16, so that they can be reset after pressing the coating. Next, the pump body 12 fills the inside of the support frame 6 with gas, so that the first steel roller body 1 can be rotated and ventilated by the first connecting grid plate 2 and the first rotating joint 3. The cold air is quickly discharged through the first connecting grid plate 2 and the second connecting grid plate 7 to prevent the continuous low temperature from affecting the subsequent coating effect. Finally, the support platform 8 and the slide 9 cooperate with the fixing plate 21 to position the connecting frame 19 to prevent the second steel roller body 23 from deviating during operation.
[0028] Through the above steps, the structure is installed on the coating machine via the support frame 6, which drives the first steel roller body 1 to press the coating film. The rotating frame 17 drives the connecting frame 19 to rotate around the first steel roller body 1, and the second support spring 18 is used to reset it. At the same time, the second steel roller body 23 is driven to press down, thereby repeatedly pressing the coating area and improving the overall coating effect. The second steel roller body 23 is rotated through the second rotating joint 22. This solves the problem that in the existing coating machine steel roller device, the steel rollers mostly press down on the steel rollers at the same time, at the same distance or at a fixed interval to apply the coating film. However, the synchronous pressing of the coating film is prone to some dispersion due to the distribution of raw materials, which leads to a decrease in the use effect of the coating machine steel roller device.
