Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of strip processing equipment, specifically relating to strip slitting equipment. Background Technology
[0002] When producing self-lubricating materials for bushings, sleeves, and other components, long strips need to be slit into narrower strips to facilitate further processing. Direct slitting using a cutting machine generates a large amount of cutting debris that adheres to the strip surface, affecting the material's self-lubricating properties. Roll cutting, on the other hand, first uses pressure rollers to create uniform indentations on the strip surface, then a slitting mechanism cuts the strip to complete the slitting. This effectively reduces debris generation. However, existing strip slitting devices have several problems in practical use. First, the strip is prone to shifting and wrinkling during slitting, making it difficult to guarantee dimensional accuracy and affecting subsequent processing quality. Second, the slitting components in traditional devices have fixed structures, making it difficult to flexibly adjust to the slitting requirements of different strip specifications, resulting in poor versatility. Third, the fit between slitting components is not tight enough, easily leading to wear and loosening under prolonged high-speed operation, which not only reduces equipment lifespan but may also pose safety hazards.

[0017] Strip slitting equipment, such as Figure 1-2 As shown, the device includes a frame 1, an upper rotating shaft 2, and a lower rotating shaft 3. The two ends of the upper rotating shaft 2 are rotatably mounted on the frame 1, and the two ends of the lower rotating shaft 3 are rotatably mounted on the frame 1. The upper rotating shaft 2 and the lower rotating shaft 3 are driven to rotate by a rotary drive mechanism. Several evenly spaced upper circular plates 4 are mounted on the upper rotating shaft 2. Two spaced pressure rings 5 are provided between adjacent upper circular plates 4. The pressure rings 5 are fixedly connected to adjacent upper circular plates 4. The outer diameter of the pressure rings 5 is larger than the outer diameter of the upper circular plates 4. Several evenly spaced lower circular plates 6 are mounted on the lower rotating shaft 3. A support ring 7 is provided between adjacent lower circular plates 6. The outer diameter of the support ring 7 is larger than the outer diameter of the lower circular plate 6. The lower circular plates 6 and the upper circular plates 4 are staggered. The middle part of the upper circular plate 4 and the middle part of the lower circular plate 6 are respectively provided with a central hole 8 for the upper rotating shaft 2 or the lower rotating shaft 3 to pass through. Before slitting, pressure rollers (in a separate unit) apply pressure to the separation area to create indentations. The indented strip enters between the upper shaft 2 and the lower shaft 3 of the slitting device. Support rings 7 support the lower surface of the strip, while pressure rings 5 act on the upper surface. As the pressure rings 5 and support rings 7 roll, a shearing action is created between them, cutting open the indentations on the strip and thus slitting it.
[0018] Furthermore, a spacing adjustment ring plate 9 is provided between adjacent upper circular plates 4, and the spacing adjustment ring plate 9 is sleeved on the upper rotating shaft 2. The number and thickness of the spacing adjustment ring plates 9 can be adjusted as needed, thereby adjusting the strip slitting width.
[0019] Furthermore, a collar 10 is fixedly connected to the pressure ring 5. The collar 10 is integrally formed with the pressure ring 5 and is tightly fitted onto the corresponding upper circular plate 4. A clamping groove 11 is formed between two collars 10 on the same upper circular plate 4 for the edge of the corresponding support ring 7 to extend into. The collar 10 and the pressure ring 5 are consumables and can be replaced periodically.
[0020] Furthermore, the collar 10 and support ring 7 are made of rubber, while the upper circular plate 4 and lower circular plate 6 are made of metal. The rubber collar 10 and support ring 7 protect the surface of the strip, preventing damage to its surface structure.
[0021] Furthermore, a plurality of keyways 12 are connected to the central hole 8, and a plurality of keys 13 are fixedly connected to the upper rotating shaft 2 and the lower rotating shaft 3 respectively, with the keyways 12 corresponding to the keys 13. The upper rotating shaft 2 drives the upper circular plate 4 to rotate through the cooperation of the keys 13 and the keyways 12, and the lower rotating shaft 3 drives the lower circular plate 6 to rotate through the cooperation of the keys 13 and the keyways 12. The upper rotating shaft 2 and the lower rotating shaft 3 are detachably mounted on the frame 1 and are rotatably mounted through bearings and the like.
[0022] Furthermore, the upper rotating shaft 2 is mounted on the slider 14 via bearings. A vertical slide rail 15 is provided on the frame 1, and the slider 14 is slidably mounted on the vertical slide rail 15. An adjusting screw 16 is rotatably connected to the slider 14, and a nut 17 is installed on the adjusting screw 16, which is then fixedly connected to the frame 1. The distance between the upper rotating shaft 2 and the lower rotating shaft 3 is adjustable, thus allowing for adjustable pressure on the strip during slitting to accommodate slitting needs of strips of different thicknesses and materials.
[0023] Furthermore, the rotary drive mechanism includes a motor, with the upper rotating shaft 2 and the lower rotating shaft 3 respectively connected to the corresponding motor via a cross-shaped universal joint drive shaft. The motor drives the upper rotating shaft 2 or the lower rotating shaft 3 to rotate via the cross-shaped universal joint drive shaft. The upper rotating shaft 2 and the lower rotating shaft 3 rotate at the same speed.
[0024] Furthermore, several limiting circular plates 18 are detachably connected to both ends of the upper rotating shaft 2 and both ends of the lower rotating shaft 3, respectively. The diameter of the limiting circular plates 18 is smaller than the diameter of the lower circular plate 6 and the diameter of the upper circular plate 4. When the number of upper circular plates 4 and lower circular plates 6 changes, the number of limiting circular plates 18 can be increased or decreased to control the center of gravity of the entire slitting device, ensuring smooth operation of the upper rotating shaft 2 and lower rotating shaft 3 and reducing vibration. The limiting circular plates 18 rotate together with the upper rotating shaft 2 or lower rotating shaft 3. The limiting circular plates 18 and the upper rotating shaft 2 or lower rotating shaft 3 can be connected by threads or by keys and keyways 12.
[0025] It is worth mentioning that the cross-shaped universal drive shaft, motor and other technical features involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control method and spatial arrangement of these technical features can be adopted by conventional choices in the field, and should not be regarded as the inventive point of this utility model patent. This utility model patent will not be further elaborated in detail.
[0026] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make many modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning or limited experimentation on the basis of the prior art should be within the scope of protection defined by the claims.
