[0060] By setting an inclined carrier plate A-11, the test paper bag can slide down to the paper outlet between the paper feed knife A-14 and the paper feed roller A-13. When the paper feed roller A-13 rotates, the test paper bag is driven and output. Since the friction force of the outer periphery of the paper feed roller A-13 is applied to the surface of the test paper bag, the roll tape is quickly output. After one test paper bag is output, the next test paper bag can fall to the paper feed roller A-13, so that the effect of quickly outputting the test paper bags one by one is achieved. The side baffle A-17 is set to limit the output position of the test paper bag, so as to ensure that the position of the test paper bag is stable and does not shift during output.

[0061] The crossbeam A-12 is provided with a guide bar A-121, and the paper feeding knife A-14 is provided with a guide groove A-141, and the guide bar A-121 is slidably connected to the guide groove A-141.

The paper feed knife A-14 is also threadedly connected to the threaded hole A-123 through the screw A-151 of the locking member A-15 passing through the long circular groove A-142.

[0066] The paper feeding roller A-13 is a polyurethane rubber roller. The polyurethane rubber roller has a large friction coefficient, thereby increasing the friction between the test paper bag and the polyurethane rubber roller, making the friction force on the test paper bag more stable during transportation.

[0067] The inner side of the lower end of the paper feeding knife A-14 is provided with an arc-shaped portion A-143. As the test paper bags are conveyed, the arrangement of the arc-shaped portion 143 makes the stacked test paper bags gradually approach the paper feeding roller 13.
