[0032] The pre-merging clamps 7, the traction wheel 3 and the long merging clamps 9 are arranged in sequence on the running route of the chain belt.
[0033] The rack 1 comprises a fixed plate 10, and the motor 2 is fixed on the fixed plate 10.
[0034] The long clamping cylinder 8 is fixed on the fixed plate 10 and arranged below the traction wheel 3. The tangent line of the rightmost end point of the traction wheel 3 is located within the opening and closing range of the two long merging clamps 9. More preferably, the tangent line of the rightmost end point of the traction wheel 3 is located at the center line position of the two long merging clamps 9. Through the above arrangement, the chain belt after coming out of the traction wheel 3 will move downward under the action of gravity and pass through the long merging clamps 9, without the need for additional traction devices to bring the chain belt to the long merging clamps 9.
[0035] The side of the fixed plate 10 further extends a fixed seat 11, and the long clamping cylinder 8 is fixed on the fixed seat 11.
