[0033] Please see Figure 3 , Figure 3This is an exploded view of the paper-splitting module, which includes a first motor drive mechanism, a paper-splitting assembly, a rubber roller assembly, a paper-splitting bracket 109, a lower housing 112, and a ticket inlet 101. The first motor drive mechanism is installed on the left side of the paper-splitting bracket and includes a motor 118, a motor gear 119, a reduction gear 110, and a drive gear 111. The motor gear 119, reduction gear 110, and drive gear 111 form a gear set and are connected to the motor 118. The motor 118 is located inside the paper-splitting bracket 109, and the motor gear 119, reduction gear 110, and drive gear 111 are installed on one side of the paper-splitting bracket 109. The drive gear 111 is connected to one end of the paper-splitting shaft 122. The paper separating assembly is installed above the lower housing 112 of the paper separator and includes a paper separating bracket 105, a paper separating spring 106, a paper separating film 114, a paper separating pressure plate 104, a handle assembly 103, an upper housing 113 of the paper separator, and a paper separator cover plate 102. The paper separator cover plate 102 is located on the top of the upper housing 113 of the paper separator, and the bottom of the upper housing 113 is connected to the top of the lower housing 112 of the paper separator. The paper separating spring 106 is located on the top of the paper separating film 114, the paper separating bracket 105 is connected to the paper separating film 114, the paper separating pressure plate 104 is located on the paper separating spring 106, and the handle assembly 103 is located on the bottom of the cover plate 102 of the paper separator and is connected to the upper housing 113 of the paper separator. The rubber roller assembly is mounted on the paper separator bracket 109 to provide power to the paper separator. It includes a paper separator shaft 122, rubber rollers 121, rubber sleeves 108, bearings 125, one-way bearings 124, and oil-impregnated bushings 123. One-way bearings 124 are sleeved on one end of the paper separator shaft 122, and bearings 125 are sleeved on the other end of the paper separator shaft 122. Rubber rollers 121 are sleeved on one-way bearings 124 and 125 respectively. Rubber sleeves 108 are sleeved on rubber rollers 121. Oil-impregnated bushings 123 are located at one end of the paper separator shaft 122 near the one-way bearings 124. The paper separator shaft 122 is connected to the first motor transmission mechanism. A paper feed sensor is provided inside the lower housing 112 of the paper separator. When a lottery ticket is inserted, the paper feed sensor is triggered. The control board receives the trigger signal from the paper feed sensor and controls the paper separator module 100 to start running and perform paper separation operations on the inserted lottery tickets.

[0034] Please see Figure 4 , Figure 4This is a cross-sectional view of the paper separating module. The paper inlet 101 is positioned diagonally above the paper separating module and contains an elastic paper-pressing roller 117 that gently presses down on the lottery tickets to prevent them from bulging. The elastic paper-separating film 114 and the soft rubber block 115 are fixed to the paper-separating bracket 105, and the paper-separating spring 106 applies elastic force to them, ensuring they are tightly adhered to the rubber sleeve 108, forming a stable paper-separating structure. When the paper inlet sensor detects paper being inserted, the motor drives the rubber roller assembly to rotate via a reduction gear. The rubber sleeve and the paper-separating pressure plate on the rubber roller assembly are tightly adhered together by the paper-separating spring. Through the friction between the rubber sleeve and the paper-separating pressure plate, the lottery tickets are separated one by one, and the separated individual lottery tickets are sequentially fed into the paper inlet channel of the lottery reader.

[0035] Please see Figure 5 , Figure 5 This is an exploded view of the lottery reading module. The outer casing includes a reader cover 201, a scanning bracket 205, an upper guide plate 210, a reader swing bracket 220, a lower guide plate 212, and a reader base 216. The scanning bracket 205 houses a scanning head 202, a paper feed detection light plate 204, a paper pressure roller 211, a paper pressure spring 203, and a handle 206. The upper guide plate 210 houses a paper feed roller 207, a scanning roller 208, and a drive gear 209. The reader swing bracket 220 houses a printhead bracket 223, a geared motor 226, and a detection plate 221. The printhead 222 is mounted on the printhead bracket 223, a cam 224 is mounted on the geared motor, and a motor cover 225 is mounted on the reader swing bracket 220 to protect the geared motor 226. A paper-pressing roller 211 and a paper-pressing spring are installed on the lower guide plate 212. The paper-pressing roller 211 presses against the rubber roller and, together with the rubber roller, winds the lottery ticket in and out. The reader base frame 216 houses the reader control board 217, the stepper motor 213, and the reduction gear 214. The reader control board 217 controls the operation of the entire machine, and the stepper motor 213 provides power to the entire machine. The bottom of the reader top cover 201 is connected to the top of the reader base frame 216.

[0036] Please see Figure 6 , Figure 6This is a cross-sectional diagram of a lottery reader. When a lottery ticket enters the reader, the paper feed sensor is triggered, and the machine begins operation. The ticket passes through the scanning head 202, which is installed inside the scanning bracket 205. The scanning bracket 205 and the reader cover 201 are fixed to the reader base frame 216 with screws featuring washers. The scanning module has a closed angle of 0° and a maximum open angle of 100°. The scanning head 202 uploads the scanning result to the host computer. If the host computer displays a winning ticket, the machine first tilts the ticket back to a certain position and then rolls it forward for branding. The branding process begins with the geared motor 226 starting, which rotates the cam 224. The print head bracket 223 and print head 222 move upwards together, pressing the print head 222 onto the scanning roller 208 for branding. The heating resistor on the print head prints the corresponding winning amount on the thermal lottery paper. After branding is complete, the geared motor 226 moves the print head 222 away from the scanning roller 208.
