[0002] A lottery machine is a device used to automatically sell lottery tickets. It consists of a variety of components. First of all, the product structure of a lottery machine mainly includes components such as a host, keyboard, printer, display, and coin slot. The host is the core part of the lottery machine. It is responsible for processing all betting information and exchanging data with the lottery center server. The keyboard is an interface for users to input information. Users can use the keyboard to enter information such as lottery numbers, issue numbers, and bet numbers. The printer is used to print lottery tickets, and the display is used to display betting information and prompt information. The coin slot is an interface for users to insert coins or banknotes, which will be automatically recognized and converted into digital amounts.

[0003] The working principle of the lottery machine is that when the user enters the betting information and puts in coins or banknotes, the host will automatically process the betting information and exchange data with the lottery center server. If the bet is successful, the printer will automatically print the lottery ticket, and the display will display the betting information and prompt information. If the bet fails, the display will show the reason for the failure, such as insufficient amount or repeated numbers.

[0004] At present, the barcode scanner uses two belts to convey lottery tickets in order to leave a gap for the beam sensor. However, there is only one adjusting roller. When the belts need to be adjusted, the two belts sometimes run to the middle at the same time, and sometimes run to both sides at the same time, which is very time-consuming and seriously affects the conveying efficiency of lottery tickets. It cannot meet the use requirements. Therefore, a belt tension adjustment device for lottery barcode scanner is proposed to solve the above problems. Utility Model Content

[0007] The tension adjustment structure comprises an adjustment roller and an adjustment shaft arranged on a mounting plate, an adjustment screw penetrating one end of the adjustment shaft and penetrating the interior of the mounting plate, and a nut threadedly connected to the exterior of the adjustment screw.

[0008] Furthermore, the number of the belts, driven rollers, adjusting rollers and adjusting shafts are two, and the two driven rollers and the two adjusting rollers are symmetrically arranged, and the two belts are respectively wound around the outside of the opposite driven rollers and adjusting rollers.

[0009] Furthermore, the two adjusting rollers are located between two driven rollers, and the driven rollers are connected to the two wall panels through bearings.

[0010] Furthermore, the number of the adjusting shafts is two, and the two adjusting shafts respectively penetrate the interior of the two adjusting rollers, and the adjusting rollers are rotatably mounted on the outer surfaces of the adjusting shafts.

[0011] Furthermore, the number of nuts in the tension adjustment structure is three, two of which are respectively against the upper and lower sides of the adjustment shaft, and the other nut is against the upper surface of the mounting plate.

[0012] Furthermore, an abutment mechanism is arranged above the wall panel, and the abutment mechanism comprises a vertical seat installed on the upper surface of the wall panel by bolts, a crossbeam welded to one side of the vertical seat, a concave frame arranged below the crossbeam, and an extrusion roller rotatably installed inside the concave frame.

[0013] Furthermore, the crossbeam is fixedly mounted with a telescopic electric cylinder extending outside the crossbeam, a connecting plate fixedly mounted on an output end of the telescopic electric cylinder, and an elastic component mounted between the connecting plate and the concave frame by bolts.

[0014] Compared with the prior art, the utility model provides a belt tension adjustment device for a lottery code scanner, which has the following beneficial effects:

[0015] 1. The belt tension adjustment device for the lottery barcode scanner has a simple and convenient structure. The height of the adjusting roller is changed by rotating the adjusting screw to achieve the purpose of adjusting the belt, thereby adjusting the tension of the belt to ensure that the belt does not run, thereby achieving the advantages of strong practicality and easy adjustment of the belt, and solving the problem of easy deviation of the belt.

[0016] 2.
