Description

Technical Field

[0001] The utility model relates to the technical field of cylindrical material processing auxiliary equipment, and in particular provides a clamping and limiting structure in a cylindrical material rotation processing process. Background Art

[0002] The processing of cylindrical materials usually requires the cylindrical materials to be rotated, but the rotation will cause the position of the cylindrical materials to shift, thus affecting the accuracy of the processing position. For example, when heat shrink packaging is performed on them, a hot air gun is required to accurately output hot air to the position that needs heat shrinkage. If the position of the cylindrical material shifts, it will affect the accuracy of the heat shrink position, thereby producing products that do not meet the regulations. Therefore, in the processing of cylindrical materials, it is necessary to clamp and limit their positions. Utility Model Content

[0014] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0015] refer to Figure 1 , Figure 2 and Figure 3 The utility model provides a clamping and limiting structure for a cylindrical material rotation processing process, comprising clamping and limiting units symmetrically arranged on both sides of the cylindrical material, each clamping and limiting unit comprising a 90° corner bracket 1, a center limiting wheel 2, a side wheel bracket 3 and a limiting side wheel 4, one end of the 90° corner bracket 1 is variably connected to the rotation processing equipment on both sides of the cylindrical material placement station, the center limiting wheel 2 is rotatably connected at the corner position of the 90° corner bracket 1, the side wheel bracket 3 comprises an integrated horizontal side wheel bracket and a vertical side wheel bracket, the horizontal side wheel bracket is variably connected to the other end of the 90° corner bracket 1, and the limiting side wheel 4 is rotatably connected to the vertical side wheel bracket with a variable angle.

[0016] During the processing of the cylindrical material 12, the cylindrical material 12 is placed on the cylindrical material placement station, and the cylindrical material is driven to rotate by the rotating processing equipment to process it. Before processing, the positions of the two 90° corner brackets 1 on the rotating processing equipment are manually adjusted so that the center limiting wheel 2 contacts the cylindrical material 12, and then the position of the side wheel bracket 3 is adjusted so that the limiting side wheel 4 contacts the edge of the cylindrical material 12, and then processing can be started, so that the cylindrical material 12 is clamped and limited during the processing.

[0017] As a specific connection method between the 90° corner bracket 1 and the rotating processing equipment, a square hole is provided on the upper cover plate of the rotating processing equipment, and a rotating driving structure is arranged in the square hole. The two 90° corner brackets 1 are variably connected to the upper cover plates 13 on both sides of the square hole, and movable grooves penetrating the square holes are provided on the upper cover plates 13 on both sides of the square hole and perpendicular to the edges of the square holes.

In the process of loosening or tightening the clamping nut 7, the big head of the inverted T-shaped screw 6 will not rotate with it, but will be stuck on the two side walls of the groove part 5 through the planes on both sides.
