Description

Technical Field

[0001] This utility model belongs to the technical field of roller holders, specifically, it relates to a roller holder for printing and dyeing. Background Technology

[0002] In the printing and dyeing production process, the roller holder is a key piece of equipment that supports the roller to complete the processes of fabric pressing and sizing. Its installation stability and compatibility with the roller directly affect the printing and dyeing quality. At present, the roller holder for printing and dyeing usually installs the roller through a fixed structure, that is, the connection part of the roller is directly clamped and fixed by the mounting seat and the fixing plate.

[0003] However, different printing and dyeing processes require the use of rollers of different diameters, and the roller holder cannot be adapted to rollers of various diameters. When replacing rollers, it is often necessary to replace the entire roller holder. Furthermore, after long-term use, rollers are prone to wear, and the diameter of the repaired rollers will become smaller. It is impossible to flexibly adjust the position of the rollers according to changes in roller diameter or process requirements.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] To address the problem that different printing and dyeing processes require rollers of varying diameters, but the roller holders cannot accommodate rollers of multiple diameters, requiring the entire roller holder to be replaced when changing rollers, and that rollers are prone to wear after long-term use, resulting in a smaller diameter after repair, making it impossible to flexibly adjust the roller position according to changes in roller diameter or process requirements, the basic concept of the technical solution adopted in this utility model is as follows: A printing and dyeing roller holder includes a base, on which two mounting plates are connected. A guide rod and a lead screw shaft are respectively mounted on the two mounting plates. A slider is slidably sleeved on the guide rod, and a slider is engaged on the lead screw shaft. A mounting seat is connected to each slider, and a bolt is connected to the mounting seat. A fixing plate is connected to the mounting seat by bolts. A replaceable lower pad and an upper pad are provided between the mounting seat and the fixing plate.

[0006] In a preferred embodiment of this utility model, both mounting plates are provided with sliding grooves, the slider is slidably installed in the sliding grooves, and the outer side wall of the slider is in contact with the inner side wall of the sliding grooves, and the guide rod and the lead screw shaft pass through the sliding grooves.

[0007] In a preferred embodiment of this utility model, one end of the lead screw shaft extends to the outer side of the corresponding mounting plate, and the extended end is connected to a knob. The knob is cylindrical, and the outer circumferential surface of the knob is provided with anti-slip ridges distributed circumferentially.

[0008] In a preferred embodiment of this utility model, the lower pad is attached to the top of the mounting base, the upper pad is attached to the bottom of the fixing plate, the lower pad and the upper pad are arranged opposite to each other, and anti-slip pads are fixedly connected to the opposite surfaces of the lower pad and the upper pad.

[0009] In a preferred embodiment of this utility model, two bolt holes are provided through the fixing plate, and a threaded hole is provided on the mounting base at the position corresponding to the bolt holes. The bolt passes through the bolt hole and is screwed into the threaded hole.

[0010] In a preferred embodiment of this utility model, the lower pad is detachably connected to the mounting base via a connector, and the upper pad is detachably connected to the fixing plate via a connector. The inner surfaces of both the lower and upper pads are arc-shaped.

[0011] Compared with the prior art, the present invention has the following advantages: This utility model allows for the replacement of lower and upper pads between the mounting base and the fixed plate, enabling the replacement of pads of different specifications to accommodate rolls of different diameters. Simultaneously, the mounting base can be moved by a lead screw and guide rod in conjunction with a slider, allowing for flexible adjustment of the roll position and further meeting the needs of different processes.

[0012] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0016] like Figures 1 to 3As shown, a printing and dyeing roller holder includes a base 1, on which two mounting plates 2 are connected. A guide rod 6 and a lead screw shaft 5 are respectively mounted on the two mounting plates 2. A slider 4 is slidably sleeved on the guide rod 6, and the slider 4 is engaged with the lead screw shaft 5. Mounting seats 7 are connected to both sliders 4, and bolts 12 are connected to the mounting seats 7. A fixing plate 8 is connected to the mounting seats 7 via bolts 12. A replaceable lower pad 9 and upper pad 10 are provided between the mounting seats 7 and the fixing plate 8. In this configuration, the two mounting plates 2 support the guide rod 6 and the lead screw shaft 5. The guide rod 6 guides the slider 4. The lead screw shaft 5, engaged with the slider 4, can rotate to move the slider 4. The two sliders 4 together support the mounting seat 7 to ensure its stable movement. The mounting seat 7 and the fixing plate 8 are connected by bolts 12 to fix the roller. The replaceable lower pad 9 and upper pad 10 can accommodate rollers of different specifications.

[0017] like Figures 1 to 3 As shown, in a specific embodiment, both mounting plates 2 are provided with sliding grooves 3. A slider 4 is slidably mounted within the sliding groove 3, with its outer sidewall fitting against the inner sidewall of the sliding groove 3. A guide rod 6 and a lead screw shaft 5 pass through the sliding groove 3. In this configuration, the sliding groove 3 provides sliding space for the slider 4. The fitting of the slider 4 against the inner sidewall of the sliding groove 3 restricts the movement direction of the slider 4. The guide rod 6 and the lead screw shaft 5, passing through the sliding groove 3 and cooperating with the slider 4, ensure that the slider 4 slides along a set trajectory.

[0018] like Figures 1 to 3 As shown, further, one end of the lead screw shaft 5 extends to the outer side of the corresponding mounting plate 2, and a knob 13 is connected to the extended end. The knob 13 is cylindrical, and its outer circumferential surface is provided with anti-slip protrusions distributed circumferentially. In this configuration, the lead screw shaft 5 extends to the outer side of the mounting plate 2 to facilitate the connection of the knob 13. The knob 13 provides a force application point for rotating the lead screw shaft 5, and the anti-slip protrusions on the outer circumference can increase friction and prevent slippage during rotation.

[0019] like Figures 1 to 3 As shown, further, the lower pad 9 is fitted to the top of the mounting base 7, and the upper pad 10 is fitted to the bottom of the fixing plate 8. The lower pad 9 and the upper pad 10 are positioned opposite each other, and anti-slip pads 11 are fixedly connected to the opposite surfaces of the lower pad 9 and the upper pad 10. In this configuration, the lower pad 9 and the upper pad 10 are positioned opposite each other to provide support for the roll from both the upper and lower sides, and the anti-slip pads 11 can increase the friction between the roll and the anti-slip pads.

[0020] like Figures 1 to 3As shown, the fixing plate 8 has two through bolt holes, and the mounting base 7 has threaded holes at the corresponding positions of the bolt holes. The bolt 12 passes through the bolt holes and is screwed into the threaded holes. In this configuration, the bolt holes provide a passage for the bolt 12, and the screwing of the threaded holes and bolt 12 can bring the fixing plate 8 closer to the mounting base 7 by tightening the bolt 12. The two bolts can evenly apply clamping force.

[0021] like Figures 1 to 3 As shown, the lower pad 9 is detachably connected to the mounting base 7 via a connector, and the upper pad 10 is detachably connected to the fixing plate 8 via a connector. The inner surfaces of both the lower pad 9 and the upper pad 10 are curved surfaces. In this configuration, the detachable connection facilitates the replacement of different lower pads 9 and upper pads 10 according to the roll specifications.

[0022] The implementation principle of a printing and dyeing roller seat in this embodiment is as follows: When installing the roller and the roller seat, simply place the connecting part of the roller on the lower pad 9 at the top of the mounting base 7, then cover the connecting part of the roller with the fixing plate 8, so that the upper pad 10 at the bottom of the fixing plate 8 is in contact with the connecting part of the roller, and then pass the bolt 12 through the bolt hole on the fixing plate 8 and screw it into the corresponding threaded hole of the mounting base 7. Through the tightening action of the bolt 12, the fixing plate 8 and the mounting base 7 cooperate to clamp the connecting part of the roller. At this time, the anti-slip pads 11 on the lower pad 9 and the upper pad 10 are in contact with the connecting part of the roller.

[0023] When it is necessary to adapt to rolls of different diameters, remove the fixing plate 8 by removing the detachable bolt 12, remove the original lower pad 9 and upper pad 10 through the connector, replace them with lower pad 9 and upper pad 10 that are compatible with the diameter of the new roll, and then re-fix it according to the above steps.

[0024] When replacing rollers of different diameters, or when the diameter of rollers becomes smaller after repair due to wear, and it is necessary to adjust the position of the rollers to meet the needs of printing and dyeing operations, the knob 13 at the extension end of the lead screw shaft 5 can be turned. The lead screw shaft 5 will rotate accordingly, and the slider 4 meshing with the lead screw shaft 5 will move along the sliding groove 3 on the mounting plate 2. At the same time, the slider 4 on the other side of the mounting plate 2 will slide synchronously along the guide rod 6. The two sliders 4 will drive the connected mounting base 7 to move, thereby driving the rollers mounted on the mounting base 7 to adjust to the appropriate position.
