Description

Technical Field

[0001] The utility model relates to the technical field of slitting machine equipment, in particular to a tension regulating device for a slitting machine. Background Art

[0002] Slitting machine, also known as slitting line, slitting machine, slitting machine, is a type of metal slitting equipment, mainly used for longitudinal shearing of metal strips, and rewinding the slit narrow strips into small coils for use in the next process.

[0003] In strip finishing equipment, aluminum foil rolling mills, and particularly slitting shears, tension is a crucial operating parameter. Existing tension generators in slitting shears primarily use hydraulic cylinders to drive a pressure plate to press down on the strip, keeping it flat during the winding process.

[0004] When the strip passes between the upper and lower platens, two layers of felt are generally placed between them to reduce damage to the strip's surface. This prevents the strip from being scratched by the platens when passing between the two layers of felt. However, due to the low friction between the felt and the platens, when the friction between the strip and the felt is greater than the friction between the felt and the platens, the felt can easily shift or even fall off, causing scratches on the strip. Summary of the Invention

[0005] In order to solve the problem that the felt in the tension generating device of the existing longitudinal shearing machine is easily displaced or even falls off, causing the strip to be scratched, the utility model proposes a tension adjusting device for the longitudinal shearing machine, by fixing a tooth plate on the side opposite to the movable seat and providing teeth on the opposite sides of the two tooth plates to increase the friction between the felt and the tooth plate. When the telescopic mechanism drives the movable seat to move downward, the tooth plate presses the felt, reducing the risk of felt displacement and improving the production quality of the strip.

[0006] In order to achieve the above purpose, the technical solution of the utility model is:

[0007] A tension adjustment device for a slitting machine, used for tensioning a strip, comprises a fixed stand and a movable seat and a fixed seat arranged vertically on the fixed stand, the strip being positioned between the movable seat and the fixed seat, the movable seat being slidably mounted on the fixed stand, the fixed seat being fixed to the fixed stand, and further comprising a telescopic mechanism, the telescopic end of which is fixedly connected to the movable seat, driving the movable seat to move up and down, tooth plates being fixed on opposite sides of the movable seat and the fixed seat, each tooth plate having teeth on opposite sides thereof, a felt being placed between the tooth plates, the felt being positioned on opposite sides of the strip, and a spring being fixed between the movable seat and the fixed seat. The spring acts as a buffer against the downward pressure of the telescopic mechanism, thereby reducing friction between the felt and the strip; the felt also serves to clean debris from the surface of the strip.

[0008] Furthermore, the telescopic mechanism is a hydraulic cylinder, which is fixed on the fixed stand, and the end of the piston rod of the hydraulic cylinder is fixed to the upper end of the movable seat.

[0009] Furthermore, a mounting groove is provided on a side of the fixed base close to the movable base, and a spring is placed in the mounting groove, with one end of the spring fixedly connected to the fixed base and the other end fixedly connected to the movable base. Alternatively, a mounting groove can be provided on a side of the movable base close to the fixed base to accommodate the spring, which has the same function as the above arrangement.

[0010] Furthermore, springs are provided on both sides of the strip.

[0011] Furthermore, the fixed stand is fixed to the ground by bolts.

[0012] Through the above technical scheme, the beneficial effects of the utility model are as follows: the utility model fixes a tooth plate on the side opposite to the movable seat and the fixed seat, and a tooth portion is fixed on the opposite side of the two tooth plates, and the felt is placed on the tooth portion. The felt is located on the upper and lower sides of the strip. When the telescopic mechanism drives the movable seat to move downward, the tooth plate bites the felt, increasing the friction between the tooth plate and the felt. The spring reduces the downward pressure of the tooth plate, reduces the friction between the felt and the strip, makes the felt less likely to displace, reduces the probability of strip wear, and improves the production quality of the strip. At the same time, the structure of the device is simple, and the felt can be easily disassembled after being used for a period of time, thereby improving production efficiency.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0017] like Figures 1 and 2 As shown, this embodiment provides a tension adjustment device for a longitudinal shearing machine, which is used to tension a strip 10, including a fixed frame 1 and a movable seat 2 and a fixed seat 3 arranged up and down on the fixed frame 1. The strip 10 is located between the movable seat 2 and the fixed seat 3. An outlet guide plate 8 and an inlet guide plate 9 are fixedly installed on both sides of the fixed frame 1 to guide the transportation of the strip 10.

[0018] Furthermore, the movable seat 2 is slidably mounted on the fixed stand 1, and the fixed seat 3 is fixed on the fixed stand 1. The movable seat 2 also includes a telescopic mechanism 4. The telescopic end of the telescopic mechanism 4 is fixedly connected to the movable seat 2, driving the movable seat 2 to move up and down. The movable seat 2 is fixed with a tooth plate 5 on the side opposite to the fixed seat 3. The tooth plate 5 is fixed to the movable seat 2 and the fixed seat 3 by welding. The two tooth plates 5 are provided with teeth on the opposite sides. The teeth are composed of a plurality of evenly arranged protrusions. Two felts 6 are placed between the two tooth plates 5. The felts 6 are located on both sides of the strip 10. The strip 10 passes through the gap between the two felts 6. A spring 7 is fixed between the movable seat 2 and the fixed stand 3. The spring 7 is provided on both sides of the strip 10. The spring 7 buffers the pressure of the hydraulic cylinder and reduces the friction between the felts 6 and the strip. The fixed stand 1 is fixed to the ground by bolts.

[0019] Specifically, the telescopic mechanism 4 is a hydraulic cylinder, which is fixed on the fixed stand 1 , and the end of the piston rod of the hydraulic cylinder is fixed to the upper end of the movable seat 2 .

[0020] In this embodiment, a mounting groove is provided on a side of the fixed seat 3 close to the movable seat 2 , and the spring 7 is placed in the mounting groove. One end of the spring 7 is fixedly connected to the fixed seat 3 , and the other end is fixedly connected to the movable seat 2 .

[0021] When in use, the strip 10 first passes through the two tooth plates 5, and the hydraulic cylinder works to adjust the gap between the two tooth plates 5. When it is in the appropriate position, the movable seat 2 stops moving downward. At this time, the two felts 6 are placed on both sides of the strip 10 respectively. The felt 6 on the upper side of the strip 10 is located on the lower side of the tooth plate 5 on the movable seat 2, and the felt 6 on the lower side of the strip 10 is located on the upper side of the tooth plate 5 on the fixed seat 3. At this time, the hydraulic cylinder is turned on again, and the teeth on the tooth plate 5 engage the felt 6. The two springs 7 between the movable seat 2 and the fixed seat 3 reduce the downward pressure of the movable seat 2, and reduce the friction between the felt 6 and the strip 10. At this time, the friction between the tooth plate 5 and the felt 6 is greater than the friction between the felt 6 and the strip 10, so that the position of the felt 6 is stable, making it not easy to displace or fall out.

[0022] The embodiments described above are only preferred embodiments of the present invention and do not limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structure, features and principles described in the patent scope of the present invention should be included in the scope of the patent application of the present invention.
