DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4A positioning device includes a transport component and a guide component, wherein the transport component includes a workbench 1, transport rollers 2 and legs 3, the legs 3 are arranged at the four corners below the workbench 1, a transport hole is arranged on the workbench 1, and a plurality of transport rollers 2 rotatably connected to the workbench 1 are arranged in the transport hole, and the guide component includes a support frame 4, a slide frame 5, a motor 6, a positive and negative threaded screw 7, a slide plate 8 and a guide plate 9, the support frame 4 is arranged on the workbench 1, the slide frame 5 is arranged below the top wall of the support frame 4, the positive and negative threaded screw 7 is arranged in the slide frame 5, the slide plate 8 is arranged in two groups of symmetrical arrangements, the upper part of the slide plate 8 extends into the slide frame 5 and is threadedly connected to the positive and negative threaded screw 7, the output end of the motor 6 passes through the slide frame 5 and is connected to the positive and negative threaded screw 7, and a guide plate 9 is also arranged below the slide plate 8.

[0022] The workbench 1 is provided with transport rollers 2, and the legs 3 provide stable support for the workbench 1. The materials are placed on the transport rollers 2. The workbench 1 is also provided with a support frame 4, and the support frame 4 provides stable support for the slide frame 5. Initially, the distance between the two groups of slides 8 is large, and the motor 6 is started. The motor 6 drives the forward and reverse screws 7 to rotate, and the two groups of slides 8 drive the guide plates 9 to move toward each other, and the guide plates 9 center and limit the materials.

[0023] During actual use, the guide plate 9 is in an inverted L-shape. If the contact area between the guide plate 9 and the material is large, it is easy to affect the stable operation of the material. For this reason, one end of the bottom wall of the guide plate 9 is connected to the slide plate 8, and a plurality of groups of rotatably connected auxiliary rollers 10 are provided on the side wall of the guide plate 9 close to the workbench 1.
