Description

Technical Field

[0001] The utility model belongs to the technical field of conveying mechanisms, and in particular relates to a conveying mechanism for a rolled PTFE tube. Background Art

[0002] PTFE tubes, or polytetrafluoroethylene tubes, have the characteristics of corrosion resistance and high temperature resistance, and are often used in chemical and other fields. PTFE (polytetrafluoroethylene) tubes have a variety of length specifications, and the common lengths are generally 1 meter, 2 meters, etc., but in actual situations, they will also vary according to different manufacturers and specific application requirements.

[0003] Publication (Announcement) No.: CN220501682U. The utility model relates to a conveying mechanism, in particular to a conveying mechanism for a rolled PTFE tube, comprising a conveying mechanism, wherein the conveying mechanism comprises a base, a fixed component is fixedly connected above the base, and a conveying roller is rotatably installed between the fixed components on both sides. The characteristic is that a support rail is arranged above the conveying mechanism, a slide groove is provided inside the support rail, a bidirectional screw is connected inside the slide groove, the bidirectional screw is slidably connected to a screw nut, and a clamping block is fixedly connected above the screw nut. In the conveying mechanism for a rolled PTFE tube, the support rail is used to prevent the PTFE tube from being stuck in the gap of the conveying roller, and the large clamping block device above the support rail can be used to fixedly convey the rolled PTFE tube, and the distance of the clamping block can be adjusted according to the thickness of the PTFE tube through the screw nut and the bidirectional screw to adapt to the fixed transportation of PTFE tubes of more sizes, which effectively improves the conveying efficiency of the PTFE tube and reduces the labor cost.

[0004] After analysis, it was found that when the rolled PTFE tube was clamped and fixed, there was no corresponding rotation adjustment structure. When running on the conveyor belt, PTFE tubes of different lengths may affect normal transportation. In addition, when the rolled PTFE tube was fixed and clamped, there would be obvious squeezing at the contact position with the PTFE tube. The overall pressure was too large, which would have a certain impact on the PTFE tube. In view of the above problems, the scheme needs to be optimized and improved. Utility Model Content

[0010] Furthermore, a knob is rotatably connected to one side of the turntable, and the knob is fixedly connected to the double-thread screw.

[0011] Furthermore, a limit plate is fixedly mounted on the turntable, and the limit plate is plug-connected with the arc-shaped clamping plate.

[0012] Furthermore, one end of the sensing block located outside the second groove is in an arc shape.

[0013] Furthermore, the arc-shaped clamping plate is slidably connected to the inner wall of the first groove.

[0014] Beneficial effects of the utility model:

[0027] From the above description, it can be seen that the rolled PTFE tube is placed between the two arc-shaped clamping plates 5, and the two arc-shaped clamping plates 5 are brought closer to each other by rotating the double-threaded screw 4 to fix the rolled PTFE tube. When in contact, the several sensing blocks 8 on the arc-shaped clamping plates 5 will contact the recessed positions between the tubes of the rolled PTFE tube, which has a better fixing effect on the PTFE tube and reduces the excessive pressure on the PTFE tube caused by local contact fixation.

[0028] As a technical optimization solution of the utility model, the rotating mechanism includes a plug-in connected pin 10 located on the turntable 2, and a positioning hole 11 and a positioning hole 2 12 are provided on the base 1 corresponding to the plug 10. The positioning hole 11 and the positioning hole 2 12 pins fit each other, and the positioning hole 11 and the positioning hole 2 12 are arranged at 90 degrees;

[0029] From the above description, it can be known that by switching the connection between the latch 10 and the positioning hole 11 and the positioning hole 2 12, the turntable 2 can be rotated quickly, which is convenient for conveying PTFE tubes of different widths.

[0030] As a technical optimization solution of the utility model, the lower side of the base 1 is symmetrically provided with a slope 13;

[0031] It can be seen from the above description that the slope 13 can make the base 1 more easily transitional when being transported on the conveyor belt.

[0033] From the above description, it can be seen that the control handle 14 can facilitate workers to lift the base 1, which is more convenient when placing it on the conveyor belt.

[0034] As a technical optimization solution of the utility model, a knob 15 is rotatably connected to one side of the turntable 2, and the knob 15 is fixedly connected to the double-threaded screw 4;

[0041] It can be seen from the above description that the sliding connection can make the arc-shaped clamping plate 5 more stable when sliding.

[0042] Working principle:

[0043] The rolled PTFE tube is placed between two arc-shaped clamping plates 5, and the two arc-shaped clamping plates 5 are brought closer to each other by rotating the double-threaded screw 4 to fix the rolled PTFE tube. When in contact, the several sensing blocks 8 on the arc-shaped clamping plates 5 will contact with the recessed positions between the tubes of the rolled PTFE tube, which has a better fixing effect on the PTFE tube and reduces the excessive pressure on the PTFE tube caused by local contact fixation. When the length of the PTFE tube is long, the rotating mechanism can quickly and effectively control the turntable to rotate 90°, so that the PTFE tube will not contact with the structure around the conveyor belt, thereby affecting normal transportation.

[0044] The above describes the utility model and its implementation methods, which are not restrictive. The specific implementation method is only one of the implementation methods of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it, without departing from the purpose of the invention of the utility model, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the utility model.
