Description

Technical Field

[0001] The present invention relates to the field of papermaking equipment, and particularly to a special arc roller for a rewinder. Background Art

[0002] The running speed of a rewinder usually exceeds 1000 m / min. In a rewinder equipped with ordinary arc rollers, when operating at high speeds, the paper will adhere to the ordinary arc rollers. In order to quickly peel off the paper at the ordinary arc rollers, the running speed of the rewinder has to be reduced. In addition, due to the small arch height of the ordinary arc rollers, when the paper width is relatively large, the effect of stretching the paper by the ordinary arc rollers is poor, which affects the working speed of the equipment, limits the paper width, results in low working efficiency of the equipment, and fails to maximize the function of the equipment. Summary of the Invention

[0003] The technical problem to be solved by the present invention is that when operating at high speeds, the paper will adhere to the ordinary arc rollers, thus affecting the working efficiency of the rewinder. To solve the above problem, the present invention provides a special arc roller for a rewinder.

[0004] The purpose of the present invention is achieved in the following way: The present invention includes two mounting bases. An arc shaft is provided between the two mounting bases. A plurality of rollers are sleeved on the arc shaft. The rollers are fixed on the arc shaft through bearings, and grooves are provided on the rollers along the circumferential direction.

[0005] One of the mounting bases is a fixed seat, and the other is an adjusting seat. Both ends of the arc shaft are respectively fixed in the fixed seat and the adjusting seat through bearings.

[0006] A mutually meshing worm and worm gear are sleeved in the adjusting seat. The worm is fixed in the adjusting seat through a bearing. One end of the worm is fixed with a handle, and the handle extends outside the adjusting seat. The worm gear is sleeved on the arc shaft.

[0007] A locking screw is sleeved on the adjusting seat.

[0008] A pointer is provided on the adjusting seat. The pointer is fixed at one end of the arc shaft, and a scale is provided on the adjusting seat.

[0009] The arch height of the arc shaft ranges from 20 mm to 40 mm.

[0010] The rollers are fixed on the arc shaft through bearings.

[0011] Compared with the prior art, by providing grooves on the arc roller, the present invention can achieve rapid peeling of the paper at the arc roller under high-speed operation, limits the arch height range of the arc roller, enables the arc roller to adapt to ultra-wide paper widths, and is also provided with an adjusting seat, which can more conveniently adjust the height of the arc roller.

[0017] Among them, 1 is the mounting base; 2 is the arc-shaped shaft; 3 is the roller; 4 is the groove; 5 is the fixed seat; 6 is the adjusting seat; 7 is the locking screw; 8 is the pointer; 9 is the handle. Specific embodiments

[0018] As shown in the attached drawings, the present invention includes two mounting bases 1. An arc-shaped shaft 2 is provided between the two mounting bases 1. The value range of the arch height of the arc-shaped shaft 2 is within the range of 20 mm to 40 mm, enabling the special arc-shaped roller of the rewinder to stretch the paper with a relatively large paper width, and further enabling the rewinder to adapt to various paper widths of the paper. A plurality of rollers 3 are arranged on the arc-shaped shaft 2. The rollers 3 are fixed on the arc-shaped shaft 2 through bearings. The bearings adopt roller bearings and are filled with lubricating grease. Grooves 4 are provided on the rollers 3 along the circumferential direction. When the arc-shaped roller is working, the rollers 3 rotate at a high speed, and air passes through the grooves 4 at a high speed to form an air flow. The air flow blows the joint between the paper and the rollers 3, enabling the paper to be quickly peeled off from the arc-shaped roller.

[0019] One of the said mounting bases 1 is a fixed seat 5, and the other is an adjusting seat 6. Both ends of the arc-shaped shaft 2 are fixed in the fixed seat 5 and the adjusting seat 6 respectively through bearings. By rotating the adjusting seat 6, the height of the arc-shaped roller can be adjusted.

[0020] A mutually meshing worm and worm gear are arranged in the adjusting seat 6. The worm is fixed in the adjusting seat 6 through a bearing. One end of the worm is fixed with a handle 9, and the handle 9 extends outside the adjusting seat 6. The worm gear is arranged on the arc-shaped shaft 2. By rotating the handle 9, the worm and worm gear are engaged to drive the arc-shaped rod to rotate, thereby adjusting the height of the arc-shaped roller.

[0021] A locking screw 7 is arranged on the adjusting seat 6. The locking screw 7 can lock the worm, so that the worm cannot rotate, and the height of the arc-shaped roller is fixed.

[0022] A pointer 8 is arranged on the adjusting seat 6. The pointer 8 is fixed at one end of the arc-shaped shaft 2 and can rotate together with the arc-shaped shaft 2. A scale is arranged on the adjusting seat 6. The height of the arc-shaped roller can be adjusted by observing the pointing of the pointer 8.

[0023] It should be noted that: the height of the arc roller of the present invention refers to the distance from the highest point of the arc roller to the horizontal plane; the arch height of the arc roller refers to the reflection of the degree of bending of the arc roller.

[0024] The working process of the present invention is as follows: First, install the arc roller on the rewinder, loosen the locking screw 7, rotate the handle 9, and the worm and worm gear are engaged for transmission, so as to adjust the height of the arc roller. Observe the direction of the pointer 8. When the height of the arc roller is adjusted to the appropriate position, stop rotating the handle 9, and then tighten the screw. The rewinder starts to work. The paper drives the roller 3 to rotate at high speed. Air passes through the grooves 4 on the surface of the roller 3 at high speed to form an air flow. The air flow blows the joint between the paper and the roller 3 to quickly peel the paper from the arc roller. Thus, the paper can be quickly peeled from the arc roller without reducing the speed of the rewinder, ensuring the working efficiency of the rewinder.

[0025] The above are only the preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, without departing from the overall concept of the present invention, several changes and improvements can still be made, and these should also be regarded as the protection scope of the present invention.
