DETAILED DESCRIPTION

[0017] The utility model is further described below in conjunction with the accompanying drawings:

[0018] like Figure 1 As shown, the utility model is a cylindrical sorting pitch-changing mechanism comprising a slideway 8 and a base plate 1, a lifting cylinder 5 is provided in the middle of the base plate 1, the cylinder shaft of the lifting cylinder 5 passes through the top surface of the base plate 1, guide columns 2 are pierced at the four corners of the base plate 1, linear ball sleeves 3 are installed on the guide columns 2, the linear ball sleeves 3 are located on the bottom surface of the base plate 1, a cylinder shaft support plate 6 is provided on the top of the cylinder shaft of the lifting cylinder 5, a movable plate 4 is connected to the top surface of the cylinder shaft support plate 6, and the four corners of the bottom surface of the movable plate 4 are respectively fixedly connected to the corresponding top surfaces of the guide columns 2; the lifting cylinder 5 drives the cylinder shaft support plate 6 to move upward or downward under the action of air pressure, so that the cylinder shaft support plate 6 moves upward or downward together with the movable plate 4, wherein the movable plate 4 can only move upward or downward under the cooperative constraint of the guide columns 2 and the linear ball sleeves 3.

[0019] The top surface of the movable plate 4 in the present utility model is provided with a hollow fixed frame 14, and a stepper motor 7 is provided at one end of the fixed frame 14. The end of the stepper motor 7 is connected to a camshaft 10 through a coupling 9, and the camshaft 10 is located at the hollow part of the fixed frame 14; a slide wheel 11 is provided on the cam groove of the camshaft 10, and a linear guide 12 is provided on the top surface of the slide wheel 11. A plurality of product carriers 13 are slidably provided on the linear guide 12, and the product carriers 13 are arranged at the output end of the slideway 8. When the stepper motor 7 starts to move, the stepper motor 7 drives the camshaft 10 to rotate through the coupling 9, so that the cam groove of the camshaft 10 moves linearly with the slide wheel 11, so that the slide wheel 11 moves with the product carrier 13 with variable pitch.

[0020] The slide 8 in the utility model includes a slide plate and two side plates, which are respectively installed on the left and right ends of the slide plate, and the tops of the two side plates are relatively provided with convex ribs, so that the product does not contact the side plates when rolling, and the product rolls on the convex ribs to reduce the resistance when the product and the side plates are in sliding contact; the slide plate and the two side plates are integrally formed, and the angle between the side plate and the slide plate is 92° to ensure that the end face of the product does not contact the two sides of the slide, reducing the risk of material jamming.

[0021] The cam groove of the camshaft 10 in the present invention is a 3D curved groove, and the accuracy of the product pitch change is guaranteed by the accuracy of the 3D curved groove. The camshaft 10 with the 3D curved groove can be processed according to the accuracy requirements, so that the product pitch change is more accurate.

[0022] The top of the product carrier block 13 in the present invention is provided with a limiting groove for placing the variable-distance product.

[0023] The use process of the utility model is as follows:

[0024] During use, when the cylindrical product enters the top of the slide 8, the lifting cylinder 5 starts to work, and the lifting cylinder 5 drives the cylinder shaft support plate 6 to move upward under the action of air pressure. At the same time, the cylinder shaft support plate 6 pushes the movable plate 4 to move upward (the movable plate 4 can only move up and down under the constraints of the guide column 2 and the linear ball sleeve 3), and the movable plate 4 carries the fixed frame 14 to move upward. The product carrier 13 on the fixed frame 14 pushes the product on the slide. At this time, the stepper motor 7 starts to work, and the stepper motor 7 drives the camshaft 10 to rotate through the coupling 9. The cam groove of the camshaft 10 moves linearly with the slide wheel 11, and the slide wheel 11 moves with the product carrier 13. The variable pitch product on the product carrier 13 follows the product carrier 13 to produce variable pitch. At this time, the rotational motion of the stepper motor 7 becomes the linear movement of the product.

[0025] Other unexplained parts of the present invention are the same as those of the prior art.
