The connecting plate 73 is vertically arranged, and the fixing plate 74 is horizontally arranged above the guide wheel through the connecting plate 73. The fixing plate 74 is provided with a first threaded through hole, and the pressing screw 76 is threadedly matched with the first threaded through hole. One end of the pressing screw 76 extending out of the upper surface of the fixing plate 74 is fixedly connected to a hand crank handle 761, and one end of the pressing screw 76 extending out of the lower surface of the fixing plate 74 is rotatably connected to the cylinder 71 through a bearing. The cylinder 71 is fixedly connected to the pressing plate 75, and the pressing plate 75 is vertically arranged. A plurality of second slide rails 731 are provided on a side of the connecting plate 73 close to the pressing plate 75. The pressing plate 75 is slidably arranged on the second slide rails 731 through a plurality of second slide seats 751, and the pressing wheel 72 is rotatably arranged on the pressing plate 75.

[0056] In this embodiment, the stroke of the cylinder 71 is fixed. By rotating the hand crank 761, the pressure screw 76 drives the lower pressure plate 75 to rise and fall. The cylinder 71 arranged on the lower pressure plate 75 is adjusted to the corresponding height for workpieces of different diameters. When the cylinder 71 reaches the maximum stroke, the lower pressure wheel 72 slightly presses the workpiece.

[0057] In order to realize automatic control of the pressing mechanism 7, as a further improvement, a control mechanism is also included, which includes a plurality of pressing-in-place sensors and a controller. The number and positions of the pressing-in-place sensors correspond to the pressing mechanism 7, and the plurality of pressing-in-place sensors and the plurality of cylinders 71 are electrically connected to the controller respectively.

[0058] When the workpiece passes through each of the down-pressing sensors in sequence, each of the down-pressing sensors transmits a control signal to the controller in sequence, and the controller controls the corresponding down-pressing mechanism 7 to press down.

[0059] When the sensor that senses that the workpiece is pressed down to the right position does not sense the workpiece, the corresponding pressing mechanism 7 rises.

[0060] As a further improvement, the pressing mechanism 7 also includes a locking plate 77, a guide rod and a locking rod. The locking plate 77 is provided with a second threaded through hole, a guide through hole and a locking through hole.

[0061] The parallelism of the locking plate 77 during the lifting and lowering process is ensured by providing a guide rod, and the guide rod is prevented from escaping from the locking plate 77 by providing a limit portion 78. By providing a control handle 79, screwing the control handle 79 drives the threaded portion to screw into the second threaded blind hole. The control handle 79 fixedly connected to the locking rod abuts against the locking plate 77 and presses the locking plate 77 in the direction close to the fixed plate 74. At the same time, the internal thread provided in the second threaded through hole abuts against and presses the external thread on the pressing screw 76. The friction between the internal thread in the second threaded through hole and the external thread on the pressing screw 76 is increased, thereby achieving circumferential and axial locking of the pressing screw 76.

[0062] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
