Description

Technical Field

[0001] The utility model relates to the technical field of steel strip transmission, especially a steel strip transmission traction system. Background Art

[0002] With the continuous development of modern industry, as an important industrial material, the production and processing technology of steel strips is also constantly improving. In the production process of steel strips, the traction device plays a crucial role, especially in the transmission and processing stages of steel strips. The performance of the traction device directly affects the quality and production efficiency of steel strips. The existing steel strip traction devices mainly use pinch rolls to traction the steel strip and make it transmit and process along a predetermined path.

[0003] By applying a traction force to the steel strip through the pinch rolls, the continuous transmission of the steel strip is realized. In the initial stage of steel strip transmission, the traction device extrudes the steel strip through the frontmost steel roll to make it enter the working area of the pinch rolls. However, in this process, the extrusion of the steel roll on the surface of the steel strip is likely to cause damage and peeling of the surface coating, thus affecting the surface quality and service performance of the steel strip. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a steel strip transmission traction system to reduce the damage to the surface coating of the steel strip.

[0005] The basic solution provided by the utility model: a steel strip transmission traction system, including a clamping wheel set, a fixed bracket and a frame; the clamping wheel set includes an upper clamping wheel set and a lower clamping wheel set; the upper clamping wheel set and the lower clamping wheel set are respectively connected to the frame through rotating shafts and the fixed bracket; the clamping wheel set is used to clamp both ends of the steel strip.

[0006] Further, it also includes a supporting wheel, and the supporting wheel is used to support the steel strip.

[0007] Further, the upper clamping wheel set includes a first upper clamping wheel and a second upper clamping wheel, and the lower clamping wheel set includes a third lower clamping wheel and a fourth lower clamping wheel.

[0008] Further, the first upper clamping wheel and the second upper clamping wheel are respectively connected to the frame through their respective rotating shafts and the fixed bracket.

[0009] Further, the third lower clamping wheel and the fourth lower clamping wheel are respectively connected to the frame through their respective rotating shafts and the fixed bracket.

[0010] Further, the first upper clamping wheel and the second upper clamping wheel can also share a rotating shaft and be connected to the frame through the rotating shaft.

[0011] Further, the third lower clamping wheel and the fourth lower clamping wheel can also share a rotating shaft and be connected to the frame through the rotating shaft.

[0012] Further, the lifting wheel and the lower clamping wheel group can also share a rotating shaft, and are connected to the frame on the fixed bracket through the rotating shaft.

[0013] The principle and beneficial effects of the utility model are as follows:

[0014] 1. By setting the clamping wheel group, the steel strip is prevented from being directly squeezed at the initial stage of transmission, thereby reducing damage to the surface of the steel strip.

[0015] 2. The design is simple, without the need for complex mechanical structures, and the manufacturing and maintenance costs are relatively low. Description of the Drawings

[0019] The following is a more detailed description through specific embodiments:

[0020] Embodiment 1

[0021] As shown in Figure 1 The steel strip transmission and traction system shown includes a clamping wheel group, a fixed bracket and a frame; the clamping wheel group includes an upper clamping wheel group and a lower clamping wheel group; the first upper clamping wheel 1 and the third lower clamping wheel 5 are respectively connected to the frame on the fixed bracket through rotating shafts; the clamping wheel group is used for clamping both ends of the steel strip 3.

[0022] In this embodiment, the upper clamping wheel group includes a first upper clamping wheel 1 and a second upper clamping wheel 2, and the lower clamping wheel group includes a third lower clamping wheel 5 and a fourth lower clamping wheel 6.

[0023] Among them, the first upper clamping wheel 1 is connected to the frame on the fixed bracket through an independent rotating shaft; the second upper clamping wheel 2 is connected to the frame on the fixed bracket through an independent rotating shaft to ensure that the upper clamping wheel group can rotate smoothly and effectively clamp the upper end of the steel strip 3 during transmission; the third lower clamping wheel 5 is connected to the frame on the fixed bracket through an independent rotating shaft; the fourth lower clamping wheel 6 is connected to the frame on the fixed bracket through an independent rotating shaft to ensure that the lower clamping wheel group can rotate smoothly and effectively clamp the lower end of the steel strip 3 during transmission.

[0024] The lifting wheel 4 is connected to the frame through a rotating shaft and a fixed bracket. The lifting wheel 4 is used to support the middle part of the steel strip 3 to prevent the steel strip 3 from collapsing during transmission due to gravity.

[0025] In addition, in other solutions, the first upper clamping wheel 1 and the second upper clamping wheel 2 can share a rotating shaft, and are connected to the frame through the rotating shaft and a fixed bracket to achieve stable installation and effective clamping of the upper clamping wheel group. The third lower clamping wheel 5, the fourth lower clamping wheel 6 and the lifting wheel 4 share a rotating shaft, and are connected to the frame through the rotating shaft and a fixed bracket, thereby ensuring the stability of the lower clamping wheel group and the lifting wheel 4.

[0026] In this embodiment, by setting the clamping wheel group and the lifting wheel 4, the shedding of the steel strip 3 due to surface coating damage can be effectively reduced. In addition, the steel strip 3 is not prone to sliding, offset or collapse during transmission, improving the stability and efficiency of transmission.

[0027] Embodiment Two

[0028] This embodiment describes a steel strip transmission and traction system, which mainly includes a pinch roller 8 and a clamping part. The pinch roller 8 is used to traction the steel strip 3 to make it move smoothly on the transmission path; the clamping part is fixedly connected to both ends of the pinch roller 8 and is used to clamp and fix both ends of the steel strip 3 to ensure that the steel strip 3 does not deviate during transmission. As Figure 2 shown, the clamping part adopts a sleeve 7 structure, and the sleeve 7 is fixed to both ends of the pinch roller 8 by welding. The welding method can ensure the firmness and reliability of the connection; the inner diameter of the sleeve 7 is designed to be slightly larger than the diameter of the pinch roller 8 to ensure that it can be smoothly sleeved on the end of the pinch roller 8 during welding.

[0029] When the steel strip 3 enters the traction system, the pinch roller 8 drives the steel strip 3 to move through rotational motion; the clamping part firmly fixes both ends of the steel strip 3 through the sleeve 7 structure to prevent the steel strip 3 from deviating from the predetermined track due to vibration or external force during transmission; the design of the sleeve 7 structure enables the clamping part to effectively disperse the pressure in the initial stage of the steel strip 3 transmission, reducing the direct extrusion of the steel strip 3 surface, thereby reducing the surface damage area.

[0030] In addition, the sleeve 7 can also be fixedly connected to the pinch roller 8 by threads.
