Description

Technical Field

[0001] The utility model relates to the technical field of guide positioning devices, in particular to a guide positioning device used for the production of polytetrafluoroethylene tubes. Background Art

[0002] PTFE tubing is a type of tubing made of polytetrafluoroethylene (PTFE) with many unique properties and a wide range of applications. It is resistant to corrosion from almost all chemicals, including strong acids, strong bases, and strong oxidizers. In the chemical industry, it can be used to transport a variety of corrosive chemicals without being damaged by corrosion. Furthermore, it does not become brittle or lose performance in low-temperature environments, such as in some cryogenic refrigeration equipment. However, during the production process of PTFE tubing, it is usually necessary to guide and position the tubing. However, current guide and positioning devices are not convenient for adjusting the positioning range according to the specifications of the PTFE tubing.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the present invention.

[0033] like Figures 1 to 4As shown, this embodiment proposes a guiding and positioning device for the production of polytetrafluoroethylene tubes, including a guide plate 1, a positioning frame 2, an adjustment plate 3, a positioning ring 4 and a positioning assembly. The positioning frame 2 is lifted and arranged on the upper side of the guide plate 1 by a lifting assembly. There are two adjusting plates 3, and the two adjusting plates 3 are slid toward each other and arranged at the top of the positioning frame 2. There are two positioning rings 4, and the two positioning rings 4 are slid toward each other and arranged at the top of each adjusting plate 3. Positioning grooves are provided on multiple positioning rings 4, and anti-slip pads 13 are fixedly connected to multiple positioning grooves to increase the stability of the positioning rings 4 in clamping and positioning the polytetrafluoroethylene tube. There are two positioning assemblies, and the two positioning assemblies are arranged between the multiple positioning rings 4. Two pull rings 14 are symmetrically connected to the top of the guide plate 1. The guide plates 1 are transported and moved by the two pull rings 14, so that the use angle of the guide plate 1 can be adjusted, thereby facilitating the adjustment of the guiding angle of the polytetrafluoroethylene tube.

[0034] refer to Figure 3 The positioning assembly includes a first electric cylinder 5 and a positioning plate 6. The first electric cylinder 5 is a double-headed electric cylinder. The first electric cylinder 5 is installed on the top of the adjusting plate 3, and a mounting groove matching the first electric cylinder 5 is opened on the adjusting plate 3, which is convenient for stable installation of the first electric cylinder 5. There are two positioning plates 6, which are respectively fixedly connected between the output end of the first electric cylinder 5 and the two positioning rings 4. The bottom end of the positioning plate 6 is fixedly connected to the limiting block 11. A limiting groove for sliding the limiting block 11 is opened on the adjusting plate 3, which is convenient for limiting the sliding of the positioning plate 6 on the adjusting plate 3, so as to increase the stability of the positioning plate 6 driving the positioning ring 4 to move;

[0035] By pulling the two adjacent positioning plates 6 toward each other through the first electric cylinder 5, the two positioning plates 6 can drive the two positioning rings 4 to move toward each other, so that the two positioning rings 4 and the two anti-slip pads 13 can cooperate to clamp and position polytetrafluoroethylene tubes of different specifications. At the same time, the position of the positioning ring 4 is relatively low, so the polytetrafluoroethylene tube can be placed directly, reducing the time waste caused by manual handling up and down.

[0036] refer to Figure 4 The lifting assembly includes a second electric cylinder 7, a lifting plate 8 and a lifting rod 9. The second electric cylinder 7 is provided in plurality, and the plurality of second electric cylinders 7 are all mounted on the top of the guide plate 1. The lifting plate 8 is fixedly connected to the output end of each second electric cylinder 7, and the lifting rod 9 is fixedly connected between each lifting plate 8 and the positioning frame 2.

[0037] By simultaneously starting multiple second electric cylinders 7, multiple second electric cylinders 7 can push the lifting plate 8 at the same time, so that the multiple lifting plates 8 drive the multiple lifting rods 9 to move simultaneously, thereby adjusting the use height of the positioning frame 2, and then facilitating the adjustment of the use height of the polytetrafluoroethylene tube through the positioning plate 6 and the positioning ring 4.

[0038] refer to Figure 2 A third electric cylinder 10 is installed on the top of the positioning frame 2. The third electric cylinder 10 is a double-headed electric cylinder.

The bottom end of the adjustment plate 3 is symmetrically connected to two sliding blocks 12. The positioning frame 2 is provided with a sliding groove for the sliding block 12 to slide, so as to increase the stability of the adjustment plate 3 sliding on the positioning frame 2;

[0039] By driving the two adjustment plates 3 to move toward each other through the third electric cylinder 10, multiple positioning plates 6 can drive multiple positioning rings 4 to move, so as to adjust the positions of the positioning plates 6 and the positioning rings 4, thereby facilitating the clamping and positioning of polytetrafluoroethylene tubes of different lengths.

[0040] In this embodiment, the third electric cylinder 10 is first started according to the specifications of the polytetrafluoroethylene tube, so that the third electric cylinder 10 moves the two adjustment plates 3 toward each other, and moves the multiple positioning plates 6 and the multiple positioning rings 4, so as to adjust the positioning position of the polytetrafluoroethylene tube. Then the polytetrafluoroethylene tube is placed between the multiple positioning rings 4, and the two first electric cylinders 5 are started at the same time, so that the first electric cylinders 5 pull the two adjacent positioning plates 6 so as to make the two adjacent positioning rings 4 approach each other, so that the multiple positioning rings 4 and the multiple anti-slip pads 13 can clamp and position the polytetrafluoroethylene tube. After the polytetrafluoroethylene tube is stably clamped, the multiple second electric cylinders 7 are started at the same time, so that the multiple lifting plates 8 drive the multiple lifting rods 9 to move at the same time, so that the positioning frame 2 drives the adjustment plate 3, the positioning plate 6 and the positioning ring 4 to move up and down, so that the use height of the polytetrafluoroethylene tube can be adjusted.
