[0035] Adjustment component 4 includes a rectangular through hole 45 at the top of the end of the unit housing 1 away from the placement platform 2. A slider 46 with a connecting bracket 41 is slidably installed in the rectangular through hole 45. The slider 46 is fixedly installed on a movable block 47. A bidirectional screw 48 is rotatably installed on the inner wall of the unit housing 1 near the rectangular through hole 45. Movable blocks 47 are threaded through the bidirectional screw 48 near both ends. The bidirectional screw 48 drives the movable blocks 47 to move relative to each other. A guide rod 49 is slidably installed through the movable block 47. The two ends of the guide rod 49 are fixed. The guide rod 49 is fixedly installed on the inner wall of the unit housing 1, serving to guide and support the moving block 47. A retractable infrared sensor 411 is fixedly installed on the side of the moving block 47 closest to the conveyor belt 3 to capture real-time changes in material position. The infrared sensor 411 monitors the offset of the galvanized sheet during transportation. A second electric telescopic rod 410 is fixedly installed on the end of the moving block 47 away from the slider 46, and the infrared sensor 411 is fixedly installed on the other end of the second electric telescopic rod 410. The inner walls of both sides of the unit housing 1... A first electric telescopic rod 43 with a correction roller 416 is slidably installed through the wall. A connecting plate 42 is fixedly installed at the end of the first electric telescopic rod 43 away from the correction roller 416. The connecting plate 42 serves to limit and stabilize the first electric telescopic rod 43. A mounting frame 417 is fixedly installed at the end of the first electric telescopic rod 43 near the correction roller 416. The correction roller 416 is rotatably mounted on the mounting frame 417. A controller 415 is fixedly installed on one side of the unit housing 1. A [unclear - possibly a device or component] is fixedly installed on the side of the unit housing 1 away from the controller 415. The second motor 44 has its output end sliding through the unit housing 1 and fixedly mounted on the bidirectional screw 48. The controller 415 and the infrared sensor 411 are electrically connected. The controller 415 is electrically connected to the electric telescopic column 413 and the first electric telescopic rod 43. The controller 415 is a digital control system responsible for signal processing and command output, which facilitates the control of the first electric telescopic rod 43 to drive the correction roller 416 to correct the galvanized sheet on the conveyor belt 3.

The clamping plate 54 is fixedly mounted on the side of the slide rod 52 near the conveyor belt 3. A first spring 53 is fixedly mounted on the side of the clamping plate 54 near the slide rod 52. The other end of the first spring 53 is fixedly mounted on the inner wall of the unit housing 1. The first spring 53 is nested on the outer surface of the slide rod 52. The first spring 53 drives the clamping plate 54 to elastically reset. A first guide plate 55 is fixedly mounted on the side of the clamping plate 54 near the placement platform 2. The first guide plate 55 guides the installation of the galvanized sheet metal. A limiting plate 57 is fixedly installed at one end away from the clamping plate 54. The limiting plate 57 serves to limit and stabilize the sliding rod 52 and the rectangular rod 51. A rectangular rod 51 is fixedly installed on the side of the limiting plate 57 closest to the clamping plate 54. The other end of the rectangular rod 51 slides through the unit housing 1 and is fixedly installed on the clamping plate 54. The rectangular rod 51, together with the sliding rod 52, plays a role in balancing and stabilizing the clamping plate 54. A sliding roller 56 is rotatably installed on the side of the clamping plate 54 away from the sliding rod 52. The sliding roller 56 reduces the friction between the galvanized sheet and the clamping plate 54, facilitates the guidance and clamping of the galvanized sheet, and ensures that the initial position of the galvanized sheet on the conveyor belt 3 is in the center, which facilitates the guidance and feeding of the galvanized sheet and improves the clamping and guiding capabilities of the device.

[0039] Example 3

[0040] Please see Figure 1 - Figure 4As shown, based on Embodiment 1 and Embodiment 2, a cleaning assembly 6 is provided on the unit housing 1 near the placement platform 2. The cleaning assembly 6 includes a telescopic rod 61 fixedly installed on the inner top wall of the unit housing 1. The telescopic rod 61 serves to support the mounting plate 63. The mounting plate 63 is fixedly installed on the end of the telescopic rod 61 near the conveyor belt 3. A first cleaning brush 64 is fixedly installed on the side of the mounting plate 63 away from the telescopic rod 61. The first cleaning brush 64 serves to clean the dust on the surface of the galvanized sheet. A second guide plate 65 is fixedly installed on the side of the mounting plate 63 near the clamping plate 54. The second guide plate 65 serves to guide the galvanized sheet to be inserted between the conveyor belt 3 and the mounting plate 63. A second spring 62 is fixedly installed on the side of the mounting plate 63 away from the first cleaning brush 64. The end of the device away from the mounting plate 63 is fixedly installed on the inner top wall of the placement platform 2. The second spring 62 is nested on the outer surface of the telescopic rod 61. The elastic restoring force of the second spring 62 drives the mounting plate 63 to drive the first cleaning brush 64 to make close contact with the galvanized sheet. The mounting plate 63 is installed between the first electric telescopic rod 43 and the clamping plate 54. A groove 68 is provided on the top surface of the placement platform 2. A limit block 67 is slidably installed in the groove 68 to facilitate the disassembly and replacement of the limit block 67 with the second cleaning brush 66. The second cleaning brush 66 is fixedly installed on the side of the limit block 67 away from the placement platform 2. The second cleaning brush 66 plays the role of cleaning the lower surface of the galvanized sheet, which facilitates the cleaning operation of the galvanized sheet, improves the cleaning ability of the device, and improves the working efficiency of galvanizing.

[0041] The working principle of this invention is as follows: When using the device, firstly, insert the limiting block 67 with the second cleaning brush 66 into the groove 68. Then, start the first motor 7, so that the output end of the first motor 7 drives the conveyor belt 3 to rotate through the drive shaft. Then, start the second motor 44, so that the output end of the second motor 44 drives the bidirectional screw 48 to rotate. The bidirectional screw 48 drives the two moving blocks 47 to move relative to each other, and at the same time, the moving blocks 47 slide on the guide rod 49. Simultaneously, the moving blocks 47 drive the slider 46 to slide in the rectangular through hole 45. Simultaneously, the slider 46 drives the connecting frame 41 to slide on the unit housing 1. At the same time, the connecting frame 41 drives the connecting plate 42 to press the first electric telescopic rod 43, so that the first electric telescopic rod 43 slides on the unit housing 1. After adjusting the distance between the two infrared sensors 411, place the galvanized sheet on the placement platform 2, and simultaneously push the galvanized sheet to slide towards the first guide plate 55 through the second cleaning brush 66. A guide plate 55 slides onto a sliding roller 56, causing the sliding roller 56 to drive the clamping plate 54 to press the rectangular rod 51, the sliding rod 52, and the first spring 53, compressing the first spring 53. Simultaneously, the rectangular rod 51 and the sliding rod 52 slide on the unit housing 1, while the conveyor belt 3 moves the galvanized sheet towards the second guide plate 65. The second guide plate 65 drives the mounting plate 63 to press the telescopic rod 61 and the second spring 62, compressing the telescopic rod 61 and the second spring 62. Simultaneously, the conveyor belt 3 moves the galvanized sheet under the first cleaning brush 64, and then the conveyor belt 3 moves the galvanized sheet to the infrared sensor 411. When the infrared sensor 411 detects that the galvanized sheet has deviated, it feeds the information back to the controller 415, causing the controller 415 to control the first electric telescopic column 413 to lift the galvanized sheet off the conveyor belt 3. At the same time, the first electric telescopic column 43 drives the correction roller 416 through the mounting frame 417 to correct the deviation of the galvanized sheet.
