Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0023] Please see Figures 1 to 5 An adjustment device for the front support roller of a coating machine includes a frame 1 for mounting the support roller, a motor 2, a synchronous guide rod 3, a worm gear assembly 4, a transmission screw 5, and a linear guide rail 6. Slide seats 7 are connected to both sides of the frame 1, and each slide seat 7 cooperates with a corresponding transmission screw 5. The transmission screw 5 is connected to the worm gear assembly 4. The driving end of one worm gear assembly is connected to the motor 2 to form the main drive force. The worm gear assemblies 4 on both sides are connected through the synchronous guide rod 3. The motor 2 provides the transmission output. The worm gear assembly on the main drive side synchronizes the movement of the transmission side and the operation side. The transmission screw 5 controls the horizontal movement of the frame 1 and the support roller, thereby adjusting the wrap angle of the roller coating machine and the amount of strip sag in the furnace behind the roller coating machine. The motor 1 involved in this utility model adopts a servo motor or other similar signal control function drive mechanism.

[0024] The adjustment system of this utility model mainly calculates the process parameters required by the unit and then inputs them into the adjustment motor to control the translation of the overall support roller (steering roller group), ultimately achieving the purpose of adjusting the wrap angle of the roll coating machine and the amount of sag of the strip behind the roll coating machine.

[0025] In one embodiment of this utility model, as follows: Figure 1 As shown, the bottom of the frame 1 is fitted with a linear guide rail 6. When the frame 1 and the support roller move horizontally, they reciprocate along the direction of the guide rail. There can be two linear guide rails 6, located inside the transmission screw. The number of guide rails is installed according to actual needs.

[0026] In one embodiment of this utility model, the sliding seats 7 connected to both sides of the frame 1 include a screw disc 71 and a seat sleeve 72. The screw disc 71 is threadedly engaged with the transmission screw 5, and the screw disc 71 is connected to the seat sleeve 72. The seat sleeve 72 is fixedly connected to the frame 1. The transmission screw 5, the worm gear assembly 4, and the synchronous guide rod 3 form a U-shaped transmission structure. A base 8 is provided below this structure for support, and the linear guide rail 6 of the frame 1 is mounted on the base 8. The transmission screw 5 is connected to the base 8 through a bearing seat, and the shaft end of the transmission screw 5 and the worm gear assembly is connected through a coupling. The worm gear assembly 4 includes a worm wheel 41, a worm 42, and a worm gear seat 43. One end of the worm 42 extends out of the worm gear seat 43 and connects to the transmission screw 5. The central axes of the worm 42 and the transmission screw 5 are on the same horizontal line and overlap. The worm of the worm gear assembly connected to the motor extends out of the worm gear seat on both sides, such as... Figure 5 As shown. Figure 2 As shown, a lifting mechanism is installed under the base 8 to adjust the vertical movement of the support roller. The lifting mechanism can be a hydraulic lift or a jack-type lift, or other equipment with lifting functions. This invention allows for adjustment of the support roller in the horizontal or vertical direction, or both, thereby adjusting the wrap angle of the roll coater and the amount of strip sag in the furnace after the roll coater.

[0027] In one embodiment, such as Figure 1 , Figure 4 , Figure 5 The worm gear 41 is located on the upper side of the screw 42. The inner side of the worm gear 41 extends outward to form a worm gear shaft. This worm gear shaft extends out of the worm gear seat 43 and is connected and fixed to the synchronous guide rod 3 through a coupling. The central axes of the worm gear shaft and the synchronous guide rod 3 are located on the same horizontal line and overlap. The positions of the worm gear and the screw can also be interchanged, and the function of synchronous transmission is within the scope of the application for protection.

[0028] like Figure 1 , Figure 2 As shown, the frame 1 is equipped with a first support roller 11 and a second support roller 12, wherein the second support roller 12 is higher than the first support roller 11, and a dust cover is provided on the outside of the frame. The strip steel bypassing the first support roller and the second support roller is conveyed to the silicon steel roll coating machine for roll coating operation.

[0029] This invention proposes a front support roller system for a coating machine suitable for oriented silicon steel roll coating machines. This support roller can be horizontally moved according to actual production needs, thereby adjusting the wrap angle of the roll coating machine and the sag of the strip behind the machine. This invention stabilizes the silicon steel strip's running trajectory by comprehensively shifting the frame and support roller, preventing vibration and improving the uniformity and quality of the coated strip.

[0030] The equipment of this utility model consists of a frame 1, a support roller (steering roller), a transmission motor (electric motor), a synchronous guide rod 3, a worm gear set 4, a transmission wire rod 5, a linear guide rail 6, and a dust cover. Figure 5 The main drive system is shown. It outputs power through motor 2, synchronizes the movement of the transmission side and the operation side through worm gear and worm wheel, and controls the horizontal movement of the entire frame through the transmission screw to adjust the wrap angle of the roll coater and the amount of strip hanging in the furnace behind the roll coater. Figure 4 The diagram shows a synchronization system that synchronizes the movements of the transmission and operation sides via two sets of worm gears. The adjustment system primarily uses the required process parameters of the unit to calculate and input the data into the adjustment motor, controlling the translation of the entire steering roller assembly to ultimately adjust the wrap angle of the roll coater and the amount of strip sag behind the roll coater.
