Description

Technical Field

[0001] This utility model relates to the field of calendering technology, specifically to an adjustable pressure roller device for calendering machines. Background Technology

[0002] Calendering, also known as pressing, is the final process in heavy leather finishing. It utilizes the plasticity of fibers under mixed heating conditions to flatten the fabric surface or create parallel, fine diagonal lines to enhance the fabric's luster. A calendering machine consists of several smooth hard and soft rollers. The hard rollers are metal rollers with highly polished surfaces or engraved with dense parallel diagonal lines, and are often equipped with heating devices. The soft rollers are fiber rollers or polyamide plastic rollers. Traditional calendering machines typically use two fixed rollers for pressing, which results in fixed and non-adjustable pressure. This causes inconvenience when calendering fabrics of different materials and thicknesses. Therefore, an adjustable pressure roller device for calendering machines is proposed. Summary of the Invention

[0003] The purpose of this invention is to provide an adjustable pressure roller device for a calender, in order to solve the problem mentioned in the background art that traditional calenders usually use two fixed rollers for extrusion, which makes the pressure of the calender fixed and unadjustable, causing inconvenience when calendering fabrics of different materials and thicknesses.

Example

[0024] Please see Figure 1-5 This utility model provides a technical solution: an adjustable pressure roller device for a calendering mill, including a mounting frame 1; and an adjustment component, which is installed inside the mounting frame 1.

[0025] By setting an adjustment component, fabrics of different thicknesses can be processed, thereby improving the versatility of the device. The adjustment component includes two slide rails 3, a slide block 4, and a fixed seat 5. The two slide rails 3 are fixedly connected to the two inner sides of the mounting frame 1, the slide block 4 is slidably connected to the outer sides of the two slide rails 3, and the fixed seat 5 is fixedly connected to the slide block 4. The inner side of the fixed seat 5 is connected to a pressure roller 6 via a fixed shaft. A long through groove 11 is opened at the left end of the mounting frame 1. A drive motor 12 is installed on the left slide block 4 between the two slide rails 3. The output shaft of the drive motor 12 is fixedly connected to one end of the fixed shaft of the pressure roller 6. A second slide groove 19 is opened on the right side of the mounting frame 1. The other end of the fixed shaft of the pressure roller 6 passes through the fixed seat 5, the slide 4 and the second slide groove 19 in sequence. The fixed roller 2 is installed on the inner side of the mounting frame 1 above the pressure roller 6 via a connecting shaft. The fixed seat 5 has a first slide groove 7 on both sides above it. The connecting shaft of the fixed roller 2 is located inside the first slide groove 7. An electric push rod 8 is installed on the top of the mounting frame 1. The push rod end of the electric push rod 8 is fixedly connected to the top of the fixed seat 5. The push rod of the electric push rod 8 drives the fixed seat 5 to move downward inside the mounting frame 1. The fixed seat 5 then drives the slide 4 to move on the slide rail 3. The pressure roller 6 moves downward away from the fixed roller 2, thus completing the adjustment of the pressure roller 6.

[0026] A guide post 9 is fixedly connected to the top of the fixed base 5. One end of the guide post 9 passes through the top of the inner side of the mounting bracket 1. A limit block 10 is fixedly connected to the top of the guide post 9. The stability of the movement of the fixed base 5 can be ensured by setting the guide post 9.

[0027] While the pressure roller 6 is being adjusted, the face gear 14 moves outside the gear post 17, enabling a drive motor 12 to drive the fixed roller 2 and the pressure roller 6 to rotate, thus improving the reliability of the device structure. A drive assembly is located on the right side of the mounting frame 1. The drive assembly includes a fixed frame 15, a rotating shaft 16, and a gear post 17. The fixed frame 15 is fixedly connected to the right side of the mounting frame 1. The rotating shaft 16 is mounted on the fixed frame 15. The gear post 17 is fixedly sleeved on the outside of the rotating shaft 16 and meshes with the outside of the face gear 14. One end of the rotating shaft 16 is fixedly connected to a second bevel gear 18, which meshes with the first bevel gear 14. On the outside of gear 13, a face gear 14 is fixedly connected to the other end of the fixed shaft of pressure roller 6. A first bevel gear 13 is fixedly connected to one end of the connecting shaft of fixed roller 2. When fixed roller 2 and pressure roller 6 need to calender the fabric, the drive motor 12 is started by controlling the switch group. The output shaft of drive motor 12 drives pressure roller 6 to rotate through the fixed shaft. The fixed shaft of pressure roller 6 drives face gear 14 to rotate. Face gear 14 drives gear column 17 on the outside of rotating shaft 16 to rotate. Rotating shaft 16 drives second bevel gear 18 to rotate. Second bevel gear 18 drives fixed roller 2 to rotate through connecting shaft. The fabric can then be calendered. The operation is simple and quick.

[0028] A housing 20 is installed on the right side of the mounting bracket 1, which provides protection for the drive components.

[0029] Working principle or structural principle: When it is necessary to adjust the distance between the fixed roller 2 and the pressure roller 6, the electric push rod 8 is extended by controlling the switch group. The push rod of the electric push rod 8 drives the fixed seat 5 to move downward inside the mounting frame 1. The guide column 9 ensures the stability of the movement of the fixed seat 5. At the same time, the fixed seat 5 drives the slide 4 to move on the slide rail 3, and the pressure roller 6 moves downward away from the fixed roller 2, thus completing the adjustment of the pressure roller 6, saving time and effort. During the movement of the fixed seat 5, the fixed shaft of the pressure roller 6 drives the face gear 14. Moving downwards, the face gear 14 moves outside the gear post 17. When the fixed roller 2 and pressure roller 6 need to calender the fabric, the drive motor 12 is started by controlling the switch group. The output shaft of the drive motor 12 drives the pressure roller 6 to rotate through the fixed shaft. The fixed shaft of the pressure roller 6 drives the face gear 14 to rotate. The face gear 14 then drives the gear post 17 outside the rotating shaft 16 to rotate. The rotating shaft 16 drives the second bevel gear 18 to rotate. The second bevel gear 18 then drives the fixed roller 2 to rotate through the connecting shaft, thus calendering the fabric. The operation is simple and quick.
