Description

Technical Field

[0001] This utility model relates to the field of printing and dyeing technology, specifically to a three-roller printing press for printing and dyeing. Background Technology

[0002] Padding machines are commonly used unit equipment in the dyeing and printing industry, with three-roll padding machines being the most prevalent type. The basic performance requirements for padding machines in the dyeing and printing industry are: after padding, the liquid retention rate on the fabric should be as uniform as possible across the front, back, left, center, and right sides, and the residual liquid should be as low as possible to avoid migration during subsequent drying, which could lead to uneven dyeing or finishing effects. Additionally, the concentration of dye liquor or finishing auxiliaries in the padding tank should also be as uniform as possible. Currently, the most ideal padding machine is the uniform padding machine, but this type of machine has a relatively complex structure and is relatively expensive.

[0003] According to announcement number CN209481983U, a three-roll mill for dyeing and printing is disclosed, including a liquid tank, an upper roll, a middle roll, and a lower roll located above the liquid tank, and multiple guide rolls distributed at the liquid tank opening and the bottom of the liquid tank. The middle roll is pressed against the upper and lower rolls respectively. The upper roll is a rubber-based upper roll; the middle roll is a cast steel-based middle roll; and the lower roll is a nylon-based lower roll. The middle roll is a drum-shaped rotating body with convex arc surfaces, where the diameters at both ends are smaller than the diameter of the roll's waist. Both the upper and lower rolls are near-cylindrical rotating bodies with concave arc surfaces, where the diameters at both ends are larger than the diameter of the roll's waist. The axis of the middle roll is flush with the liquid surface in the liquid tank. This method features a simple structure, low cost, more uniform rolling pressure, lower roll residue, more uniform concentration of dye liquor or finishing agent in the rolling trough, and applicability to both dip-rolling and surface-rolling methods, resulting in more ideal performance.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, it is clear that while the aforementioned equipment can solve the problems of uneven rolling, insufficient roll residue, and uneven concentration of dye liquor or finishing agent in the rolling trough, it is only suitable for the dip-rolling method and the effect is not ideal. However, during use, when the roller body needs to be repaired or replaced due to long-term rolling and cracking of the rubber body, wear of the cast steel body surface, corrosion of the nylon body, etc., the user needs to use a variety of tools to gradually disassemble the side guard plate of the frame and unscrew multiple fixing bolts. The entire disassembly and assembly process is cumbersome and time-consuming, which is not convenient for the maintenance of the roller body. Utility Model Content

The dustproof shell is sleeved on the surface of the ball bearing.

[0009] In a preferred embodiment of this utility model, the limiting mechanism includes a bearing seat, which is movably mounted on the surface of the rotating shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by setting up a disassembly and assembly mechanism and a limiting mechanism, enables the disassembly and assembly mechanism to directly disassemble and assemble the roller body, greatly reducing the disassembly and assembly steps and shortening the preparation time for roller body maintenance or replacement. At the same time, the limiting mechanism can effectively limit and fix the roller body's rotating shaft, preventing the roller body from shifting or shaking due to force during the printing and dyeing pressing process, ensuring that the three sets of roller bodies always maintain a precise relative position, thereby ensuring the uniformity of fabric pressing and maintaining the stability of the roll residue rate. It solves the problem that when the roller body needs to be repaired or replaced due to long-term pressing, such as rubber body aging and cracking, cast steel body surface wear, nylon body corrosion, etc., users need to use multiple tools to gradually disassemble the frame side guard plate and unscrew multiple fixing bolts.

[0014] 2. The disassembly and assembly mechanism of this utility model fixes the arc-shaped disassembly seat with an L-plate, and directly connects the rotating shaft of the roller body to the inner wall of the arc-shaped disassembly seat. This replaces the traditional complicated method of disassembling the side guard plate of the frame and unscrewing multiple bolts. During maintenance, there is no need to use multiple tools. The rotating shaft can be taken out from the arc-shaped disassembly seat after the limit is released, which greatly reduces the disassembly and assembly steps and shortens the operation time.

[0015] 3. The limiting mechanism of this utility model is mounted on the surface of the rotating shaft through a bearing seat. It works with a bidirectional screw to drive the connecting plate to move the limiting block. It can quickly clamp or unlock the rotating shaft. Compared with the traditional bolt fixing method, there is no need to unscrew the bolts one by one. The limit state can be switched by starting the forward and reverse motors through the control box, which greatly shortens the preparation and finishing time of roller assembly and disassembly.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0021] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0022] Example 1 Reference Figure 1-3 This is the first embodiment of the present invention, providing a three-roll printing press for dyeing and printing, including a three-roll press 1. The three-roll press 1 includes a liquid tank 11, guide rollers 12, roller bodies 13, and a rotating shaft 14. The guide rollers 12 are movably connected to both sides of the inner wall of the liquid tank 11. The roller bodies 13 are located on the left side of the top of the liquid tank 11, and the number of roller bodies 13 is arranged in three sets and evenly distributed. The rotating shaft 14 is fixedly connected to both sides of the roller bodies 13. Disassembly / assembly mechanism 2; The disassembly / assembly mechanism 2 includes an L-plate 21, which is fixedly connected to both sides of the front and rear sides of the liquid tank 11. The L-plate 21 is disposed on both sides of the rotating shaft 14. An arc-shaped disassembly seat 22 is fixedly connected to the inner side of the L-plate 21. Three sets of arc-shaped disassembly seats 22 are provided. The rotating shaft 14 is movably connected to the inner wall of the arc-shaped disassembly seat 22. An auxiliary component 23 is provided on the inner wall of the arc-shaped disassembly seat 22. A dustproof component 24 is provided on the inner side of the L-plate 21. Limiting mechanism 3; limiting mechanism 3 is movably installed on the surface of rotating shaft 14. Auxiliary component 23 includes arc groove 231, which is opened on the inner wall of arc-shaped disassembly seat 22. Ball bearings 232 are movably embedded on the surface of rotating shaft 14. The number of ball bearings 232 is set in several groups and is distributed in a ring at equal distances. The surface of ball bearings 232 is movably connected to the inner wall of arc groove 231. Dustproof component 24 includes disassembly slide 241, which is opened on the inner side of L plate 21. The number of disassembly slide 241 is set in three groups. A slider 242 is movably connected to the inner wall of disassembly slide 241. A dustproof shell 243 is fixedly connected to the inner side of slider 242. The dustproof shell 243 is sleeved on the surface of ball bearings 232. A pull block 5 is fixedly connected to the top of dustproof shell 243. A lifting hole 6 is opened on the surface of pull block 5.

[0023] Specifically, the disassembly and assembly mechanism 2 fixes the arc-shaped disassembly seat 22 through the L plate 21, and directly connects the rotating shaft 14 of the roller body 13 to the inner wall of the arc-shaped disassembly seat 22. This replaces the traditional complicated method of disassembling the side guard plate of the frame and unscrewing multiple bolts. During maintenance, there is no need to use multiple tools. The rotating shaft 14 can be taken out from the arc-shaped disassembly seat 22 after the limit is released, which greatly reduces the disassembly and assembly steps and shortens the operation time.

[0024] Furthermore, when maintenance is required on the roller body 13 of the three-roll mill 1, the user can reach into the lifting hole 6 on the surface of the pull block 5 and apply upward pulling force to move the dust cover 243. Under the action of the pulling force, the slider 242 will slide upward along the inner wall of the disassembly and assembly groove 241 and be pulled outward until the slider 242 is completely disengaged from the disassembly and assembly groove 241. At this time, the dust cover 243 can be removed from the surface of the ball bearing 232. When it is necessary to disassemble the roller body 13, the user can directly pull the roller body 13 upward. At this time, the ball bearing 232 on the surface of the rotating shaft 14 will separate from the inner wall of the arc groove 231 without the need for complicated tools. Easily pull the rotating shaft 14 out of the arc-shaped disassembly seat 22 to complete the disassembly of the roller body 13. When installing a new roller body 13, simply align the rotating shaft 14 with the arc-shaped disassembly seat 22 and align the ball bearings 232 with the arc-shaped groove 231 to achieve quick installation of the roller body 13, facilitating replacement or maintenance of the roller body 13. After maintenance or replacement of the roller body 13, the ball bearings 232 rolling in the arc-shaped groove 231 assist the rotating shaft 14 and roller body 13 in rotation, thereby converting rotational friction into rolling friction. Then, the user holds the pull block 5 through the lifting hole 6 and aligns the slider 242 inside the dust cover 243 with L. The disassembly and assembly slide 241 on the plate is then pushed down, and the pull block 5 is pushed down to make the slider 242 slide along the inner wall of the disassembly and assembly slide 241 until the slider 242 slides completely into the bottom of the disassembly and assembly slide 241. At this time, the dust cover 243 is just fitted on the surface of the ball 232, so as to protect the arc groove 231 and the ball 232 from dust, and ensure the stability and smoothness of the ball 232 and the arc groove 231 during the subsequent rotation of the rotating shaft 14.

[0025] Example 2 In the second embodiment of this utility model, the limiting mechanism 3 includes a bearing seat 31, which is movably mounted on the surface of the rotating shaft 14. Limiting blocks 32 are movably connected to both sides of the bearing seat 31. A connecting plate 33 is fixedly mounted on the outer side of the limiting blocks 32. Sliding plates 34 are fixedly connected to both sides of the front and rear sides of the liquid tank 11. The connecting plate 33 is movably connected to both sides of the inner wall of the sliding plate 34. An adjusting component 35 is fixedly mounted on the left side of the sliding plate 34. The adjusting component 35 includes a forward and reverse motor 351, which is fixedly mounted on the left side of the sliding plate 34. A bidirectional screw 352 is fixedly connected to the output end of the forward and reverse motor 351. The right side of the bidirectional screw 352 is movably connected to the right side of the inner wall of the sliding plate 34 through a bearing. A threaded hole 353 is opened on the surface of the connecting plate 33. The inner wall of the threaded hole 353 is threadedly connected to the surface of the bidirectional screw 352. A control box 4 is fixedly mounted on the left side of the liquid tank 11. The control box 4 is electrically connected to the forward and reverse motor 351 through a wire.

[0026] Specifically, the limiting mechanism 3 is mounted on the surface of the rotating shaft 14 through the bearing seat 31. In conjunction with the bidirectional screw 352, the connecting plate 33 drives the limiting block 32 to move, which can quickly clamp and limit or release and unlock the rotating shaft 14. Compared with the traditional bolt fixing method, there is no need to unscrew the bolts one by one. The limit state can be switched by starting the forward and reverse motor 351 through the control box 4, which greatly shortens the preparation and finishing time of disassembly and assembly of the roller body 13.

[0027] Furthermore, after the roller body 13 is installed, the user can send a control signal to the forward and reverse motors 351 via the operation buttons on the control box 4. When the limit needs to be adjusted, the control box 4 controls the forward and reverse motors 351 to rotate forward, driving the bidirectional screw 352 to rotate forward, causing the connecting plates 33 on both sides to move further relative to each other. The clamping force of the limit block 32 on the bearing seat 31 increases, thereby limiting the bearing seat 31 and allowing the rotating shaft 14 to rotate stably. When the roller body 13 malfunctions and needs maintenance, the user sends a reverse signal to the forward and reverse motors 351 via the control box 4. 51. The forward and reverse motor 351 drives the bidirectional screw 352 to reverse. The connecting plate 33, which is threadedly connected to the bidirectional screw 352, slides in the opposite direction along the inner wall of the sliding plate 34. The connecting plate 33 drives the limit blocks 32 on both sides away from the bearing seat 31 until the limit blocks 32 are completely disengaged from the bearing seat 31. At this time, the fixing of the rotating shaft 14 is released, and the user can smoothly carry out the subsequent disassembly and assembly of the roller body 13. The entire limit release process does not require the use of additional tools and can be quickly completed through the control box 4, which further improves the convenience of roller body 13 maintenance and effectively shortens the maintenance time.

[0028] Working principle: When the roller 13 requires maintenance due to long-term rolling, such as aging and cracking of the rubber body, wear of the cast steel body surface, and corrosion of the nylon body, the user can reach into the lifting hole 6 of the top pull block 5 of the dust cover 243 to drive the slider 242 inside the dust cover 243 to slide upward along the disassembly and assembly groove 241 inside the L plate until the slider 242 is completely disengaged from the disassembly and assembly groove 241. The dust cover 243 can then be removed from the ball bearing 232 on the surface of the rotating shaft 14, exposing the mating part between the rotating shaft 14 and the arc-shaped disassembly seat 22. At this time, the control box 4 transmits the signal to the forward and reverse motor 351 on the left side of the sliding plate 34 through the wire. The forward and reverse motor 351 drives the bidirectional screw 352 fixed at the output end to reverse. Since the surface of the bidirectional screw 352 is threadedly connected to the threaded hole 353 of the connecting plate 33, and the connecting plate 33 is movable, the user can easily remove the dust cover 243 ... surface of the rotating shaft 14, exposing the ball bearing 242 on the surface of the rotating shaft 14, exposing the ball bearing The rotating shaft 14 is dynamically connected to the inner wall of the sliding plate 34. When the bidirectional screw 352 reverses, it drives the connecting plates 33 on both sides to slide in the opposite direction along the inner wall of the sliding plate 34. The connecting plates 33 then drive the outer fixed limiting block 32 away from the bearing seat 31 sleeved on the surface of the rotating shaft 14 until the limiting block 32 is completely disengaged from the bearing seat 31, releasing the limiting fixation on the rotating shaft 14. After the limiting is released, the user can directly pull the roller body 13 upwards, and the rotating shaft 14 can be easily pulled out from the inner wall of the arc-shaped disassembly seat 22 without the need for additional tools, thus completing the disassembly of the roller body 13. To facilitate maintenance of the roller body 13, when installing a new roller body 13, simply align the rotating shaft 14 with the arc-shaped disassembly seat 22, align the ball bearings 232 with the arc-shaped groove 231, and use the rolling action of the ball bearings 232 to smoothly push the rotating shaft 14 into the arc-shaped disassembly seat 22, achieving quick installation of the roller body 13. After the roller body 13 is installed, once again align the slider 242 of the dust cover 243 with the disassembly groove 241 through the lifting hole 6 of the pull block 5, and push the pull block 5 downward to make the slider 242 slide into the bottom of the groove, and the dust cover 243 is re-sleeved onto it. The surface of the ball bearing 232 is dustproofed to protect the mating parts of the ball bearing 232 and the arc groove 231, ensuring the stability of subsequent rotation. After the roller body 13 is installed in place, the forward and reverse motor 351 drives the bidirectional screw 352 to rotate forward. The connecting plates 33 on both sides move relative to each other along the inner wall of the sliding plate 34. The limiting block 32 fits tightly against both sides of the bearing seat 31 to limit and fix the rotating shaft 14, preventing the roller body 13 from shifting or shaking due to force when pressing the fabric, and ensuring that the three sets of roller bodies 13 distributed at equal distances always maintain a precise relative position.

[0029] In summary, by setting up the disassembly and assembly mechanism 2 and the limiting mechanism 3, the disassembly and assembly mechanism 2 can directly disassemble and assemble the roller body 13, greatly reducing the disassembly and assembly steps and shortening the preparation time for maintenance or replacement of the roller body 13. At the same time, the limiting mechanism 3 can effectively limit and fix the rotating shaft 14 of the roller body 13, preventing the roller body 13 from shifting or shaking due to force during the printing and dyeing pressing process. This ensures that the three sets of roller bodies 13 always maintain a precise relative position, thereby ensuring the uniformity of fabric pressing and maintaining the stability of the roll residue rate. This solves the problem that when the roller body needs to be repaired or replaced due to long-term pressing, such as rubber body aging and cracking, cast steel body surface wear, nylon body corrosion, etc., users need to use multiple tools to gradually disassemble the frame side guard plate and unscrew multiple fixing bolts. The entire disassembly and assembly process is cumbersome, time-consuming, and inconvenient for roller body maintenance. This achieves the effect of convenient maintenance.
