[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The scanner with a highly stable correction structure is provided with a horizontal frame, a lifting rod, a scanning plate, a scanning head assembly body, a bidirectional motor body), a bidirectional motor body, a rotating shaft, a first connecting plate, a first contact roller, a rotating column, a first transmission mechanism, a first gear, a second gear, a second connecting plate, a second contact roller, a limiting rod and a limiting frame. When in use, firstly, a document or object to be scanned is placed on the surface of a conveyor belt body, and then the product is conveyed through the conveyor belt body. During the conveying process, the product to be scanned is scanned through the scanning head assembly body, and the scanning plate can be lifted and lowered through the lifting rod, so that the height of the scanning plate can be adjusted according to the actual height of the product. When the lifting rod is used After that, the two sets of lifting rods are started at the same time, and the lifting rods will drive the scanning plate to move upward. If the scanning plate is in an inclined and non-horizontal state, the lifting rods will stop moving when the surface of the scanning plate contacts the lower surface of the horizontal frame, and the bidirectional motor body will be started at this time. The bidirectional motor body drives the rotating shaft to rotate, and then the rotating shaft will drive the first connecting plate to rotate counterclockwise, and the first connecting plate will drive the first contact roller to rotate when it rotates, so that the first contact roller will contact the lower surface of the scanning plate when it rotates, and then the first connecting plate will drive the rotating column to rotate, and then the rotating column drives the first transmission mechanism to rotate, and the first transmission mechanism drives the first gear to rotate, and the first gear is meshed with the second gear. At this time, the second gear starts to drive the second connecting plate to rotate, and then the second connecting plate starts to rotate clockwise. Rotate, then the second connecting plate drives the second contact roller to contact the lower surface of the scanning plate, so that the lower surface of the scanning plate can be contacted during the rotation of the first contact roller and the second contact roller, and then after the contact, the upper surface of the scanning plate will contact the lower surface of the horizontal frame. This design can quickly correct the scanning plate to ensure that the left and right ends of the scanning plate are in a horizontal state. At the same time, the scanning plate will contact the spring ball when it contacts the horizontal frame. The spring ball can enhance the fitting effect of the scanning plate. At the same time, the spring ball is squeezed by the scanning plate and enters the inside of the groove for storage. Then, when the bidirectional motor body is rotating, the first bevel gear column rotates, the first bevel gear column meshes with the second bevel gear column, and the second bevel gear column drives the second transmission mechanism When the first gear is moved to the left, the second gear is engaged with the gear train, and ...When the limiting roller fits the product, it can also limit the surface of the product to a certain extent, and then flatten the surface of the product by moving the limiting roller. Then the flattening roller will roll on the surface of the product again to flatten the surface of the product, ensuring that there will be no wrinkles on the surface of the product, so that the entire product can be completely scanned when it is scanned later. Similarly, the first rack plate can also complete the same operation and flatten the surface of the product as a whole. This design can firstly quickly calibrate the scanning plate and the scanning head assembly after the lifting rod is lifted and used, and the surface of the product can also be limited and flattened during the process of the product being transported by the conveyor belt body, which solves the problem that the scanning head assembly is easy to deviate during use and wrinkles appear during product transportation, reflecting the functionality of the design.

[0019] 2. The scanner with a highly stable correction structure has a bevel gear assembly, a bidirectional screw rod, a mounting plate, a movable jet frame and an air outlet. When the rotating column is in use, the rotating column drives the bevel gear assembly to rotate, and then the bevel gear assembly drives the bidirectional screw rod to rotate. The position of the bevel gear assembly can be limited by the mounting plate. Before the correction operation is performed, that is, when the lifting rod drives the scanning plate and the scanning head assembly to rise and fall as a whole, the movable jet frame on the outer surface of the bidirectional screw rod will reciprocate in opposite directions, and then the gas can be sprayed through the air outlet to the scanning plate. The upper surface of the scanning plate is cleaned, so that after the gas is sprayed through the outlet, the upper surface of the scanning plate can be cleaned. By cleaning the upper surface of the scanning plate, it is possible to avoid the scanning plate and the scanning head as a whole from tilting after subsequent correction operations. If there are impurities in the contact between the upper surface of the scanning plate and the lower surface of the horizontal frame, the scanning plate will still be in a tilted and uneven state when it completely contacts the lower surface of the horizontal frame. By cleaning the surface of the scanning plate, the problem of the scanning plate being uneven after contact with the horizontal frame can be solved, which reflects the ingenuity of the design.

An inclined frame 37 is installed on the left side of the connecting frame 35, and a limiting roller 38 is installed on the lower end of the inclined frame 37. A groove 44 is opened at the lower end of the horizontal frame 6, and a spring ball is arranged inside the groove 44. One end of the spring ball is installed on the inner wall of the horizontal frame 6. The lower end of the second bevel gear column 25 is inserted and installed inside the scanner bottom plate 1, and the lower end of the second transmission mechanism 26 is inserted and installed inside the scanner bottom plate 1. A limiting frame 29 is provided on the outer surface of the movable frame 28, and the limiting frame 29 is installed on the top surface of the operating frame 23. The connecting block 34 set at the lower end of the first rack plate 31 is installed at the same position as the connecting block 34 set at the lower end of the first rack plate 31. Symmetrically, firstly, the documents or objects to be scanned are placed on the surface of the conveyor belt body 2, and then the products are conveyed through the conveyor belt body 2. The products can be documents, photos, materials and physical products, etc. During the conveying process, the products to be scanned are scanned by the scanning head assembly 9, and the scanning plate 8 can be lifted and lowered by the lifting rod 7, so that the height of the scanning plate 8 can be adjusted according to the height of the actual product. When the lifting rod 7 is used, the two sets of lifting rods 7 are started at the same time, and the lifting rod 7 will drive the scanning plate 8 to move upward. If the scanning plate 8 is in an inclined and non-horizontal state, when the surface of the scanning plate 8 contacts the lower surface of the horizontal frame 6, the lifting rod 7 stops moving, and the two-way The motor body 11, the bidirectional motor body 11 drives the rotating shaft 12 to rotate, and then the rotating shaft 12 will drive the first connecting plate 13 to rotate counterclockwise, and when the first connecting plate 13 rotates, it drives the first contact roller 14 to rotate, so that when the first contact roller 14 rotates, it will contact the lower surface of the scanning plate 8, and then the first connecting plate 13 will drive the rotating column 15 to rotate, and then the rotating column 15 drives the first transmission mechanism 16 to rotate, and the first transmission mechanism 16 drives the first gear 17 to rotate, and the first gear 17 is meshed with the second gear 18. At this time, the second gear 18 starts to drive the second connecting plate 19 to rotate, and then the second connecting plate 19 starts to rotate clockwise, and then the second connecting plate 19 drives the second contact roller 20 to contact the lower surface of the scanning plate 8.Therefore, the first contact roller 14 and the second contact roller 20 can contact the lower surface of the scanning plate 8 during the rotation process, and then after the contact, the upper surface of the scanning plate 8 will contact the lower surface of the horizontal frame 6. This design can quickly correct the scanning plate 8 to ensure that the left and right ends of the scanning plate 8 are in a horizontal state. At the same time, the scanning plate 8 will contact the spring ball when it contacts the horizontal frame 6. The spring ball can enhance the fitting effect of the scanning plate 8. At the same time, the spring ball is squeezed by the scanning plate 8 and enters the interior of the groove 44 for storage. Then, when the bidirectional motor body 11 is rotating, the first bevel gear column 24 rotates, and the first bevel gear column 24 meshes with the second bevel gear column 25. The second bevel gear column 25 drives the second transmission mechanism 26 to rotate. At this time, the second transmission mechanism 26 will drive the rotating disk 27 to rotate, and the rotating disk 27 will drive the convex column to rotate. Then, when the rotating disk 27 and the convex column rotate, they will drive the movable frame 28 to reciprocate left and right. The movement of the movable frame 28 is limited by the limit frame 29. Then the movable frame 28 will drive the lower connecting plate 30 and the first rack plate 31 to reciprocate left and right. When the first rack plate 31 moves to the right, the first rack plate 31 meshes with the installation gear 32. At this time, the installation gear 32 meshes with the second rack plate 33. At this time, the movement direction of the second rack plate 33 is opposite to that of the first rack plate 31. The connecting block 34 will move with the second rack plate 33, and the connecting block 34 will drive the connecting frame 35 to move to the left. At the same time, the flattening roller 36 inside the connecting frame 35 will move on the surface of the product, and the inclined frame 37 and the limiting roller 38 will also fit the surface of the product during the movement. The limiting roller 38 can also limit the surface of the product to a certain extent when it fits the product. Then, the surface of the product will be flattened by the movement of the limiting roller 38, and then the flattening roller 36 will roll on the surface of the product again to flatten the surface of the product, ensuring that there will be no wrinkles on the surface of the product, so that the entire product can be completely scanned when it is scanned subsequently. Similarly, A rack plate 31 can also perform the same operation and flatten the surface of the product as a whole. The present design can firstly perform a quick calibration operation on the scanning plate 8 and the scanning head assembly body 9 after the lifting rod 7 is used, and the surface of the product can also be limited and flattened during the process of the product being conveyed by the conveyor belt body 2, which solves the problem that the scanning head assembly body 9 is easy to deviate during use and wrinkles appear during product conveyance. After the calibration is completed, the bidirectional motor body 11 rotates in the opposite direction, and the first contact roller 14 and the second contact roller 20 do not contact the lower surface of the scanning plate 8, and then the above operation is cycled, and the first bevel gear column 24 can always perform a rotation operation.

[0037] Working principle: When the staff uses the device, first connect the device to an external power supply to provide power support for the device, first place the documents or objects to be scanned on the surface of the conveyor belt body 2, and then convey the products through the conveyor belt body 2. During the conveying process, the products to be scanned are scanned through the scanning head assembly 9, and the scanning plate 8 can be lifted and lowered through the lifting rod 7, so that the height of the scanning plate 8 can be adjusted according to the actual height of the product. When the lifting rod 7 is used, the two sets of lifting rods 7 are started at the same time, and the lifting rod 7 will drive the scanning plate 8 to move upward. If the scanning plate 8 is in an inclined and non-horizontal state, when the surface of the scanning plate 8 contacts the lower surface of the horizontal frame 6, the lifting rod 7 stops moving, and at this time the bidirectional motor body 11 is started, the bidirectional motor body 11 drives the rotating shaft 12 to rotate, and then the rotating shaft 12 drives the first connecting plate 13 to rotate counterclockwise, and when the first connecting plate 13 rotates, it drives the first contact roller 14 to rotate, so that when the first contact roller 14 rotates, it will contact the lower surface of the scanning plate 8, and then the first connecting plate 13 drives the rotating column 15 to rotate, and then the rotating column 15 drives the first transmission mechanism 16 to rotate, and the first transmission mechanism 16 drives the first gear 17 to rotate, and the first gear 17 is meshed with the second gear 18, and at this time the second gear 18 starts to drive the second connecting plate 19 to rotate, and then the second connecting plate 19 starts to rotate clockwise, and then the second connecting plate 19 drives the second contact roller 20 to also contact The lower surface of the scanning plate 8 can be in contact with the lower surface of the scanning plate 8 during the rotation of the first contact roller 14 and the second contact roller 20. Then, after the contact, the upper surface of the scanning plate 8 will contact the lower surface of the horizontal frame 6. This design can quickly correct the scanning plate 8 to ensure that the left and right ends of the scanning plate 8 are in a horizontal state. At the same time, the scanning plate 8 will contact the spring ball when it contacts the horizontal frame 6. The spring ball can enhance the fitting effect of the scanning plate 8. At the same time, the spring ball is squeezed by the scanning plate 8 and enters the interior of the groove 44 for storage. Then, when the bidirectional motor body 11 is rotating, the first bevel gear column 24 rotates, the first bevel gear column 24 engages with the second bevel gear column 25, and the second bevel gear column 25 drives the second transmission The driving mechanism 26 rotates, and the second transmission mechanism 26 will drive the rotating disk 27 to rotate, and the rotating disk 27 will drive the convex column to rotate. Then, when the rotating disk 27 and the convex column rotate, the movable frame 28 will be driven to reciprocate left and right. The movement of the movable frame 28 is limited by the limit frame 29. Then the movable frame 28 will drive the lower connecting plate 30 and the first rack plate 31 to reciprocate left and right. When the first rack plate 31 moves to the right, the first rack plate 31 is meshed with the mounting gear 32. At this time, the mounting gear 32 is meshed with the second rack plate 33. At this time, the movement direction of the second rack plate 33 is opposite to that of the first rack plate 31. At this time, the connecting block 34 will move with the second rack plate 33, and the connecting block 34 will drive the connecting frame 35 to move to the left.At the same time, the flattening roller 36 inside the connecting frame 35 will move on the surface of the product, and the inclined frame 37 and the limiting roller 38 will also fit on the surface of the product during the movement, and the limiting roller 38 can also limit the surface of the product to a certain extent when fitting on the product, and then the surface of the product will be flattened by the movement of the limiting roller 38, and then the flattening roller 36 will roll on the surface of the product again to flatten the surface of the product, and similarly, the first rack plate 31 can also perform the same operation to flatten the surface of the product as a whole;,
