[0007] A further improvement plan is that the horizontal moving device is supported and fixed by a mounting seat, the mounting seat includes a horizontal top plate and an end plate at one end of its lower surface, a vertical plate at the rear side, and mounting blocks at both ends of the front side of the vertical plate. The motor is fixed on the outer surface of the end plate, the ball screw connected to the motor output shaft is movably installed on the two mounting blocks, and the linear guide rail is installed on the lower surface of the horizontal top plate above the ball screw.
[0008] A further improvement is that the nut of the ball screw is fixed on a connecting block, and the connecting block is fixedly connected to a slider of the upper linear guide and a cylinder seat of a slide cylinder on the front side.
[0009] A further improvement is that the tooth plate is fixed on the slide of the slide cylinder through a tooth plate mounting block, and the two tooth plates are respectively fixed on the front and rear side walls of the tooth plate mounting block.
[0010] A further improvement is that a detection plate is connected to the translation member of the horizontal moving device, and a sensor is fixedly provided on the frame behind the detection plate. Beneficial Effects
[0011] The rack of the device fixes and supports the long edge of the bottom towel that needs to be folded at four points, so that the folding width is increased to 35mm, which can well ensure that the folded edge end is not exposed, thereby ensuring the production quality of the towel.
