[0002] In all types of examinations, invigilators need to verify the number of answer sheets before and after the exam to ensure that no answer sheets are missing or incorrect. With the development of education and the increasing prevalence of various examinations, the scale of examinations is constantly expanding. After each examination, the large number of answer sheets to be counted and packaged places a heavy burden on examination staff. Traditional manual counting and packaging methods not only waste time and manpower but are also prone to confusion. Therefore, there is an urgent need for automated equipment to improve work efficiency.
[0003] Currently, manual counting is the norm, which is labor-intensive, time-consuming, and prone to errors under high-intensity work, thus affecting exam organization. Furthermore, some devices rely on manual bundling of stacks of answer sheets, making it difficult to adjust the width of the collection rack according to the answer sheet specifications. This hinders the neat packing of stacks by the strapping machine, reducing the device's efficiency and practicality. Therefore, to address these technical problems, this application proposes an automatic counter with answer sheet packing functionality. Summary of the Invention

[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. The card twisting mechanism of this utility model includes a drive motor, a rotating rod, a twisting roller, a lifting frame, a pushing rod, a pressure plate, and springs. First, the spring pushes the pressure plate downwards, allowing it to work in conjunction with the sliding card holder to tightly press a stack of answer sheets. Then, the drive motor is activated via the control console, causing the rotating rod and the twisting roller to rotate to a limit position. This causes the twisting roller to pull the answer sheets above the sliding card holder into the card feeding frame sequentially, thus twisting the answer sheets. The photosensitive counter inside the card feeding frame can then count the sequentially fed answer sheets, facilitating accurate sorting of a predetermined number of answer sheets and improving the efficiency and practicality of the device.
[0016] 2. The servo motor, movable screw, and pusher screw in the adjustment mechanism of this utility model are included. First, the servo motor is started via the control console. The servo motor drives the movable screw to rotate at a limit position. The movable screw drives the pusher screw to slide left and right. The pusher screw drives the collection rack to rotate synchronously, realizing the adjustment of the collection rack. This allows some parts of the device to adjust the width of the card holder of the collection rack according to the specifications of the answer sheets, making it easier for the strapping machine to neatly pack a stack of answer sheets, thus improving the adjustability and practicality of the device.
