Description
Technical Field
[0001] The utility model relates to the technical field of steel coil processing, in particular to a length-fixing device used for steel coil production. Background Art
[0002] Currently, steel coil processing often relies on a sizing device to accurately control the amount of steel coil delivered. Existing sizing devices typically consist of a frame, a drive motor, active rollers, and passive rollers (for example, Chinese Patent Publication No. CN208374040U discloses a novel lift-adjustable servo-type sizing feeder). The drive motor is mounted on the frame, while the active and passive rollers are parallel to each other and connected to the drive motor.
[0003] During use, the end of the steel coil passes between the active roller and the driven roller. At this time, the active roller and the driven roller jointly clamp the end of the steel coil; then the drive motor is started (the drive motor can also be turned on first to make the active roller rotate slowly), so that the active roller rotates, and the friction force of the active roller on the end of the steel coil is used to move the end of the steel coil to the next workstation (usually the cutting workstation, where the purpose is to achieve accurate control of the cutting amount through quantitative transportation). In this way, the driving motor controls the rotation amount of the outer circumference of the active roller to control the transfer amount of the steel coil end.
[0004] Because the driven roller moves as the active roller moves the coil end, the sensitivity of the driven roller's own rotation can easily affect the accuracy of coil end delivery. Over time, dust, flocs, and insects can enter the connection between the driven roller and the frame, reducing the smoothness of the driven roller's rotation. This can lead to uneven friction on both sides of the coil end, reducing coil end delivery accuracy, and significantly impacting coil processing quality.
[0005] Therefore, it is necessary to redesign the structure of the sizing device. Utility Model Content

[0023] like Figure 1 and Figure 2 As shown, the utility model describes a sizing device for steel coil production, comprising a frame 1, a drive motor 2, a gear transmission box 3, and a transfer roller group 4, wherein the gear transmission box 3 is provided with two synchronously rotating power output shafts 31, the drive motor 2 and the gear transmission box 3 are arranged on or beside the frame 1, and the input end of the gear transmission box 3 is driven and connected to the drive motor 2, and the transfer roller group 4 includes two transfer rollers 41, which are arranged on the frame 1 in parallel with each other, and the two transfer rollers 41 are driven and connected to the two power output shafts 31 respectively.
[0024] The use of a gear transmission box 3 in this sizing device ensures extremely stable and reliable power transmission. A single drive motor 2 drives the gear transmission box 3, which is equipped with two synchronously rotating power output shafts 31. The two transfer rollers 41 are also driven and connected to the two power output shafts 31. This not only greatly improves the synchronization of the rotation of the two transfer rollers 41, but also maintains this synchronization at a high level over a long period of time. This allows the sizing device to maintain high transfer accuracy over a long period of time, thereby maintaining a high level of steel coil production quality. This ensures extremely high reliability and applicability.
[0025] like Figure 1 and Figure 2 As shown, the two transfer rollers 41 are respectively connected to the two power output shafts 31 through the universal coupling 5. This not only reduces the difficulty of processing and assembling related components, but also ensures that the power transmission is very stable and reliable, thereby helping to further improve the reliability and applicability of the sizing device.
[0026] like Figure 1 and Figure 2 As shown, the universal joint 5 is a ball cage type universal joint, which can make the power transmission more stable and reliable, thereby further improving the reliability.
[0027] like Figure 3 As shown, the frame 1 includes a fixed frame 11, a movable frame 12, and a lifting drive 13. The lifting drive 13 is mounted on the fixed frame 11. The movable frame 12 is mounted on the fixed frame 11 so as to be vertically movable and connected to the lifting end of the lifting drive 13. Two transfer rollers 41 are arranged side by side, with the lower transfer roller 41 mounted on the fixed frame 11 and the upper transfer roller 41 mounted on the movable frame 12. This allows for stable adjustment of the spacing between the two transfer rollers 41, thereby facilitating the transfer of steel coil ends of different thicknesses, and thereby increasing the applicability of the sizing device.
[0028] like Figure 3 As shown, the lifting drive 13 is a vertically arranged driving cylinder or driving cylinder or electric push rod, and the movable frame 12 is limited on the fixed frame 11 by a vertically arranged linear guide rail 14, which can meet the actual manufacturing and use requirements.
[0029] like Figure 3As shown, the frame 1 is provided with a limiting roller set 6 for rolling and clamping the end of the steel coil, and the limiting roller set 6 and the transfer roller set 4 are arranged side by side along the moving direction of the steel coil end. In this way, the limiting roller set 6 can limit the position of the steel coil end before entering the transfer roller set 4, thereby facilitating a smoother entry of the steel coil end onto the transfer roller set 4, thereby improving the accuracy and stability of the transfer of the steel coil end.
[0030] like Figure 3 As shown, the limiting roller group 6 includes a driving cylinder 61 and two limiting rollers 62. The driving cylinder 61 is mounted on the frame 1. The two limiting rollers 62 are arranged parallel to each other. One of the limiting rollers 62 is mounted on the driving end of the driving cylinder 61, and the other limiting roller 62 is mounted on the frame 1. The driving cylinder 61 is configured to drive the adjacent limiting roller 62 to reciprocate away from and toward the other limiting roller 62. This facilitates adjustment of the spacing between the two limiting rollers 62, thereby facilitating appropriate limiting of the ends of steel coils of different thicknesses, thereby helping to expand the applicability of the sizing device.
[0031] like Figure 3 As shown, in actual manufacturing, the driving cylinder 61 is vertically mounted on the fixed frame 11, the two limiting rollers 62 are arranged side by side, and the upper limiting roller 62 is connected to the driving end of the driving cylinder 61 through the mounting frame 63, and the lower limiting roller 62 is rotatably mounted on the fixed frame 11. This can meet the requirements of actual manufacturing and use, and can ensure excellent performance.
[0032] like Figure 1 、 Figure 2 and Figure 4 As shown, the transfer roller 41 comprises a steel cylinder 411 and two positioning steel shafts 412. Positioning ring grooves 4111 are provided at both ends of the steel cylinder 411. One end of each positioning steel shaft 412 is embedded in the two positioning ring grooves 4111. The other ends of the two positioning steel shafts 412 are rotatably embedded in the frame 1, and the other end of one of the positioning steel shafts 412 is drivingly connected to the corresponding power output shaft 31. A rubber layer 413 is provided on the circumferential surface of the steel cylinder 411. The use of the steel cylinder 411 not only controls the amount of material used but also provides the transfer roller 41 with high structural strength. The rubber layer 413 prevents the ends of the steel coil from being pinched and, when the ends of the steel coil are coated, prevents damage to the coating. The positioning ring grooves 4111 facilitate accurate installation and positioning of the positioning steel shafts 412, thereby facilitating the convenient and accurate installation and positioning of the positioning steel shafts 412. The use of the positioning steel shaft 412 can ensure that the installation connection has better structural strength, thereby being conducive to improving the stability and reliability of the installation connection. This helps to further improve the reliability and applicability of the transfer roller 41.
[0033] The positioning steel shaft 412 and the steel cylinder 411 can be further fixed by welding, which can further improve the reliability of the transfer roller 41.
[0034] like Figure 1 and Figure 2 As shown, the input end of the gear transmission box 3 is connected to the drive motor 2 via a gearbox 7. This can make the power output more stable, thereby further improving the reliability of the sizing device.

This achieves the purpose of independently arranging the gear box 3, the gearbox 7, and the drive motor 2, thereby facilitating assembly and maintenance. It also reduces the amount of horizontal space occupied, making it convenient for use in a small workshop environment, thereby increasing the scope of application. In this way, the frame 1 does not need to be made too large to accommodate the gear box 3, the gearbox 7, and the drive motor 2, thereby reducing the manufacturing difficulty.
[0037] like Figure 1 As shown, a protective net 9 is provided on or beside the positioning frame 8 to shield the gear transmission box 3, the transmission connection between the gear transmission box 3 and the gearbox 7, and the transmission connection between the gear transmission box 3 and the transfer roller 41.
