[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 4 The diagram shows a scanner for uploading electronic tax invoices, including a tail box 1 and a material conveying structure 2 installed inside the front end of the tail box 1. The material conveying structure 2 includes a U-shaped base plate 21. The front end of the tail box 1 is open, and the U-shaped base plate 21 is fixedly connected to the bottom of the front end. Material conveying rollers 24 are rotatably connected inside the U-shaped base plate 21 through two parallel rotating shafts 22. The two material conveying rollers 24 are connected by a conveyor belt 26. A horizontally arranged rectangular guide rail 28 is installed on the top of the tail box 1 at the top of the conveyor belt 26. A curved limiting top plate 23 is installed at the bottom of the middle position of the rectangular guide rail 28. A motor 25 is installed on one outer side of the tail box 1. The output of the motor 25 rotates through the side and is fixedly connected to the adjacent rotating shaft 22.

[0020] It is worth noting that the tail box 1 is connected to the rear end of the original comparison document's paper feed roller and paper separator. When the invoice paper is fed into the material feeding structure 2 area, the motor 25 is turned on. The motor 25 drives the connected rotating shaft 22 to rotate. Since the two feeding rollers 24 are connected by the conveyor belt 26, the two feeding rollers 24 rotate synchronously, and the conveyor belt 26 starts to run, feeding the invoice paper forward along the conveyor belt 26. During the feeding process, the rectangular guide rail 28 plays a guiding role, ensuring that the invoice paper can move along the predetermined direction, while the curved limiting top plate 23 can prevent the invoice paper from deviating or tilting during the feeding process, ensuring that the invoice paper can enter the subsequent scanning area smoothly and accurately to complete the uploading and scanning of the tax electronic invoice. Compared with the traditional guide rail feeding method, it is flatter and improves the scanning quality. Moreover, the subsequent feeding method reaches the designated position and drops the material, making the invoice receiving process interleaved and preventing messy receiving.

[0021] Please refer to Figure 1 , Figure 2 and Figure 3 Several pads 101 are fixedly connected to the bottom of both sides of the tail box 1. The pads 101 are made of rubber and have a certain elasticity and anti-slip properties. They can effectively increase the friction between the tail box 1 and the placement surface, prevent the tail box 1 from shifting due to vibration or other reasons during equipment operation, and ensure the overall stability of the equipment operation.

[0022] Please refer to Figure 1 , Figure 2 and Figure 3 The rectangular guide rail 28 has rectangular limiting side plates 27 installed at both ends of its bottom. First sliding sleeves 201 are slidably fitted at both ends of the rectangular guide rail 28, and first bolts 202 are installed on the top of each first sliding sleeve 201. The first bolts 202 are used to fix the position of the first sliding sleeves 201 on the rectangular guide rail 28. When the position of the first sliding sleeves 201 needs to be adjusted, simply loosen the first bolts 202, slide the first sliding sleeves 201 to the desired position, and then tighten the first bolts 202. This design allows the relative position between the rectangular guide rail 28 and the first sliding sleeves 201 to be flexibly adjusted according to actual usage requirements to meet the conveying requirements of invoice paper of different specifications. The rectangular limiting side plates 27 restrict the lateral movement of the invoice paper during conveying, further ensuring that the invoice paper can be accurately conveyed along the path set by the rectangular guide rail 28.

[0023] Please refer to Figure 1 , Figure 2 and Figure 3 The bottom side wall of the rectangular limiting side plate 27 is in contact with the top surface of the conveyor belt 26. This contact design allows the rectangular limiting side plate 27 to better limit the invoice paper laterally, preventing the invoice paper from shifting or falling during the conveying process.

[0024] Please refer to Figure 1 , Figure 2 and Figure 4 A second sliding sleeve 203 is slidably fitted at the middle position of the rectangular guide rail rod 28. A second bolt 204 is threadedly connected to the top of the second sliding sleeve 203. A telescopic rod 205 is fixedly connected to the bottom of the second sliding sleeve 203. The telescopic end of the telescopic rod 205 is fixedly connected to the top of the curved limiting top plate 23. A third bolt 206 is installed on the telescopic rod 205. The second bolt 204 is used to fix the position of the second sliding sleeve 203 on the rectangular guide rail 28. Its operation is similar to that of the first bolt 202; by loosening or tightening the second bolt 204, the position of the second sliding sleeve 203 on the rectangular guide rail 28 can be flexibly adjusted. The design of the telescopic rod 205 allows the height of the curved limiting top plate 23 to be adjusted according to actual needs, meeting the limiting requirements of invoice paper of different thicknesses. When it is necessary to adjust the height of the curved limiting top plate 23, simply loosen the third bolt 206, then adjust the length of the telescopic rod 205, and finally tighten the third bolt 206. This design makes the entire device more adaptable and flexible, better meeting the usage needs in different scenarios.

[0025] See Figure 1 , Figure 2 and Figure 3An adjustable scanner mounting structure 3 is installed at the center of the rear box 1. The adjustable scanner mounting structure 3 includes a cylindrical guide rail 31. The cylindrical guide rail 31 is installed near the center of the rear box 1. A perforated slider 33 is sleeved in the middle of the cylindrical guide rail 31. Two symmetrically arranged arc-shaped clamping plates 32 are fixedly connected to the top of the perforated slider 33. A fourth bolt 34 is threaded to the rear side of the perforated slider 33.

[0026] The cylindrical guide rail 31 provides a stable sliding track for the perforated slider 33, ensuring smooth movement of the slider 33. Two symmetrically arranged arc-shaped clamping plates 32 are used to fix the scanner, ensuring a stable installation on the perforated slider 33 without wobbling. The fourth bolt 34 is used to fix the position of the perforated slider 33 on the cylindrical guide rail 31. When the position of the scanner needs to be adjusted, simply loosen the fourth bolt 34, move the perforated slider 33 to the appropriate position (angle adjustment is also possible), and finally tighten the fourth bolt 34. This design allows the scanner's installation position to be flexibly adjusted according to actual needs. The purpose of this flexibility is that the barcode or QR code on invoices is typically placed in the upper left corner or other areas. The comparison document sets the scanner in the fixed middle area, which limits its applicability.

[0027] See Figure 1 , Figure 3 and Figure 4 The rear end of the tail side box 1 is equipped with a material collection structure 4, which includes a feeding box 41. The bottom and rear end face of the tail side box 1 are provided with a material collection channel 44, and the feeding box 41 is provided in the material collection channel 44. The adjacent sides of the feeding box 41 are open, and a pull ring 43 is fixedly connected to the rear end face of the feeding box 41. The feed box 41 is detachably installed inside the tail box 1 via the collection channel 44, making installation and removal of the feed box 41 extremely convenient. When cleaning or replacing the feed box 41 is required, it can simply be pulled out of the collection channel 44 using the pull ring 43. The open design of the feed box 41 facilitates the collection of scanned invoices, ensuring a smooth scanning process. The sedimentation method for collecting invoices prevents collisions and interference between the collected invoices, resulting in neater and more aesthetically pleasing storage and facilitating subsequent invoice organization.

[0028] The tail side box 1 is located on both sides of the material collection channel 44 and has connected sliding grooves 45. The two outer sides of the feed box 41 are fixedly connected with matching sliding rods 42.

[0029] The slide bar 42 can slide within the slide groove 45. The cooperation between the slide bar 42 and the slide groove 45 further enhances the stability of the feed box 41 during installation and removal, ensuring that the feed box 41 will not shake or shift during movement. This ensures that the feed box 41 can be accurately and smoothly installed into the collection channel 44 and removed from it, thus improving the reliability and convenience of the entire device.
