Description

Technical Field

[0001] This utility model relates to the field of fabric flat-width dyeing and finishing rolling mill technology, specifically a rolling mill roll with balanced pressure. Background Technology

[0002] Currently, the most commonly used rolling mills in the flat-width dyeing and finishing process of fabrics are ordinary three-roll or two-roll rolling mills. The pressure is applied to the shafts at both ends of the rollers. This pressure method results in greater bending deformation in the middle of the rollers. Combined with the rigidity of the roller material, this leads to greater deflection deformation, causing the pressure on the middle of the fabric to be much lower than on the sides. Therefore, after the fabric is rolled, the amount of liquid carried in the middle section is much greater than on the sides. When this type of rolling mill rolls the liquid inside and outside the fabric with linear pressure, the greater the pressure applied, the greater the amount of liquid squeezed out of the fabric. At the same time, the greater the pressure, the greater the bending deformation and deflection deformation of the rollers. The higher the linear pressure on the sides and the lower the pressure in the middle, the more uneven the liquid carried in the fabric becomes, forming a convex shape. This results in a large amount of liquid carried, leading to significant waste of auxiliaries, high energy consumption, low production capacity, and poor environmental performance. Utility Model Content

[0003] The purpose of this invention is to provide a rolling mill roll with balanced pressure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rolling mill roll for balancing pressure, comprising a high-carbon balancing mandrel, wherein a plurality of self-aligning roller bearings are fixedly mounted on the high-carbon balancing mandrel, the outer ring of the self-aligning roller bearings is fixedly connected to a high-carbon inner roller body, a balancing roller body is provided outside the high-carbon inner roller body, a transmission sprocket is fixedly connected to one side of the high-carbon inner roller body, and a transparent cover is fixedly connected to the side of the high-carbon inner roller body away from the transmission sprocket.

[0005] Preferably, the roller surface of the high-carbon inner roller body is composed of a special polymer with a mesh-like micro-gap structure, and the interior of the high-carbon inner roller body is hollow.

[0006] Preferably, each of the self-aligning roller bearings has a lubrication channel on one side.

[0007] Preferably, the self-aligning roller bearings are evenly distributed on the high-carbon balance mandrel, and limiting sleeves are provided between the two sides of the high-carbon balance mandrel and the adjacent self-aligning roller bearings.

[0008] Preferably, a baffle plate is provided on the outer surface of the transparent cover.

[0009] Compared with the prior art, the beneficial effects of this utility model are: through the design and manufacturing of the high-carbon inner roller body and the balance roller body, the roller body itself, through the scientific structure, infinitely fits the two sets of pressure rollers on the roller surface, automatically balancing the linear pressure acting on the fabric evenly. After adjustment, the rotation knob can be increased to the required process production speed, which can effectively improve the production capacity, ensure the continuous process production of the fabric, and output the fabric in a flat state to the next process production unit, thus achieving efficient, uniform, energy-saving, and emission-reducing production. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the overall structure of this utility model.

[0011] In the diagram: 1. High-carbon balance mandrel; 2. Self-aligning roller bearing; 3. High-carbon inner roller body; 4. Balance roller body; 5. Drive sprocket; 6. Lubrication channel; 7. Through cover. Detailed Implementation

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0013] Please refer to 1, an embodiment of this utility model: a pressure-balancing rolling mill roll, including a high-carbon balancing mandrel 1, a plurality of self-aligning roller bearings 2 fixedly mounted on the high-carbon balancing mandrel 1, a high-carbon inner roller body 3 fixedly connected to the outer ring of the self-aligning roller bearings 2, a balancing roller body 4 mounted outside the high-carbon inner roller body 3, a transmission sprocket 5 fixedly connected to one side of the high-carbon inner roller body 3, and a cover 7 fixedly connected to the side of the high-carbon inner roller body 3 away from the transmission sprocket 5. When the roll is pressurized, the pressure is transmitted to the axial pressure contact line of the high-carbon inner roller body 3 and the balancing roller body 4 through the internal self-aligning roller bearings 2. Due to the inward shift of the pressurization position and the scientific and even distribution to specific dimensions, the deflection deformation and bending deformation are reduced by about 25 times under linear use of the roll. Therefore, under normal working line pressure, the bending deformation of the balancing roller is 1 / 25 of that of the ordinary roll, thereby effectively controlling the uniformity of the liquid distribution and the liquid carry-over rate in the fabric, and at the same time increasing the production line speed by 15%.

[0014] The roller surface of the high-carbon inner roller 3 is made of a special polymer with a mesh-like micro-gap structure. When the surface is pressed, it can elastically adhere to the fabric and can withstand high pressure and tearing force. The interior of the high-carbon inner roller 3 is hollow. By infinitely adhering to the fabric, it ensures that the linear pressure is effectively applied to the inside and outside of the fabric, squeezing out the liquid on the fabric to reduce the amount of liquid on the fabric.

[0015] Each side of the self-aligning roller bearing 2 is provided with a lubrication channel 6, which allows lubricant to be added to the internal self-aligning roller bearing 2.

[0016] The self-aligning roller bearings 2 are evenly distributed on the high-carbon balance mandrel 1. Limiting sleeves are provided between the two sides of the high-carbon balance mandrel 1 and the adjacent self-aligning roller bearings 2. The position of the self-aligning roller bearings 2 is restricted by the limiting sleeves to prevent them from falling off the high-carbon balance mandrel 1.

[0017] A baffle plate is provided on the outer surface of the cover 7 to prevent external liquids from entering the interior.

[0018] Working Principle: This rolling mill is easy to operate. Through efficient roller design and manufacturing, an automatically injected slurry tank, and opening the clutch knob of the pressure roller feeding device, the fabric is threaded between two or more sets of pressure rollers. Guided by the guide rollers, it passes through the active traction area and reaches the next production unit. When needed, the power is turned on, the active roller rotates, the pressure rollers are opened, and the speed knob is adjusted to low. The two or more sets of pressure rollers move to a point of contact through the pressure feeding device and apply pressure to the working pressure. During the roller's extrusion and rotation, the pressure output remains stable. Then, through the design and manufacturing of the high-carbon inner roller body 3 and the balancing roller body 4, the rollers themselves, through scientific structure, infinitely conform to the linear surfaces of the two sets of pressure rollers, automatically balancing the linear pressure acting on the fabric evenly. After adjustment, the speed knob is increased to the desired production speed, effectively improving production capacity, ensuring continuous fabric production, and outputting the fabric in a flat state to the next production unit, achieving efficient, uniform, energy-saving, and emission-reducing production.
