Description

Technical Field

[0001] The utility model relates to the technical field of edge sealing equipment, in particular to an edge sealing device for a pre-oxidized fiber integrated felt. Background Art

[0002] The pre-oxidized fiber integrated felt is a polymer material. The pre-oxidized fiber integrated felt has good thermal stability, corrosion resistance, moisture resistance, wear resistance and excellent electrical properties, and can resist high temperature, low temperature, acid-base corrosion and other environmental conditions, with strong durability after long-term use. At present, the pre-oxidized fiber integrated felt is widely used in the fields of air filtration, water treatment, medical and health, industrial filtration, aerospace, communication optical fiber, new energy, etc. During the production and processing of the pre-oxidized fiber integrated felt, the edges of the pre-oxidized fiber integrated felt are prone to wear and wire drawing, and both phenomena affect the service life and use effect of the pre-oxidized fiber integrated felt. Therefore, edge sealing processing is required for the pre-oxidized fiber integrated felt.

[0003] The existing method for edge sealing processing of the pre-oxidized fiber integrated felt is to use edge strips for sewing edge sealing processing. The edge sealing steps are as follows: first, take an edge strip and wrap it around one side edge of the pre-oxidized fiber integrated felt, and then the staff uses a sewing machine to sew and seal the side wrapped with the edge strip. According to the above steps, the other three side parts of the pre-oxidized fiber integrated felt are wrapped with edge strips and sewn and sealed one by one. Among them, the edge strip used for edge sealing can be the edge material of the pre-oxidized fiber integrated felt itself or a special edge strip. The above existing edge sealing processing method for the pre-oxidized fiber integrated felt can only perform edge sealing processing on one side edge of the pre-oxidized fiber integrated felt each time, with relatively cumbersome operation, time-consuming and laborious, high labor intensity of workers and low work efficiency. Therefore, we propose an edge sealing device for a pre-oxidized fiber integrated felt to solve the above problems. Summary of the Utility Model

[0022] Refer to Figure 1 、 Figure 2 and Figure 3 , the present utility model provides an edge sealing device for the whole pre-oxidized fiber felt, including a platform 1. Legs 2 are fixedly installed at the four corners of the bottom of the platform 1. The four legs 2 can stably support the platform 1, where:

[0023] There are two horizontal chutes 3 opened at the top of the platform 1. Horizontal sliding seats 4 are slidably installed in both of the two horizontal chutes 3. The tops of the two horizontal sliding seats 4 respectively extend outside the corresponding horizontal chutes 3. Bearing plates 5 are fixedly installed on the tops of the two horizontal sliding seats 4. Driving components and pressing components are arranged on the tops of the two bearing plates 5. Sewing machines 10 are arranged on both of the two driving components. Sewing needles 11 are fixedly installed on both of the two sewing machines 10. The above-mentioned driving components include electric guide rails 7, electric sliding seats 8 and support plates 9. A longitudinal chute 6 is opened at the top of the bearing plate 5. The electric guide rail 7 is fixedly installed on the bottom inner wall of the longitudinal chute 6. The electric sliding seat 8 is slidably installed on the electric guide rail 7. The top of the electric sliding seat 8 extends outside the longitudinal chute 6. The support plate 9 is fixedly installed on the top of the electric sliding seat 8. The sewing machine 10 is detachably and fixedly installed on the top of the support plate 9. By using the linear sliding fit of the electric sliding seat 8 on the electric guide rail 7, the support plate 9 and the sewing machine 10 can be controlled to move linearly in the longitudinal direction (front-back direction), and then the side parts of the pre-oxidized fiber overall felt can be automatically sewn and edge-sealed by using the sewing machine 10. The pressing component is used to press and fix the side part of the pre-oxidized fiber overall felt on the bearing plate 5. The above-mentioned pressing component includes a U-shaped frame 12, an electric telescopic rod 13, a pressing plate 14 and an anti-slip pad 15.

Connecting holes 18 are formed in the inner walls of the two mutually adjacent lateral sliding grooves 3. The connecting rod 19 is rotatably installed in the connecting hole 18 through a bearing.

It should be added that the motor 20 is a reversible motor.

[0024] In this embodiment, a plurality of first balls are nested at the bottom of the support plate 9. The plurality of first balls are distributed in two columns. All the plurality of first balls are in rolling contact with the top of the bearing plate 5, improving the smoothness of the linear movement of the support plate 9.

[0025] In this embodiment, a horizontal guide rod 24 is fixedly installed in the lateral sliding groove 3. The lateral sliding seat 4 is slidably sleeved on the horizontal guide rod 24, playing a role in guiding the sliding direction of the lateral sliding seat 4, so that the lateral sliding seat 4 can maintain a horizontal linear movement.

[0026] In this embodiment, a plurality of second balls are nested at the bottom of the bearing plate 5. The plurality of second balls are distributed in two columns.

[0028] With the above structure, when the edge sealing device for the PAN fiber integrated felt provided by the utility model is in use, it can automatically sew and seal the two side parts of the PAN fiber integrated felt simultaneously, improving the work efficiency and reducing the labor intensity. During specific operation, by controlling the motor 20 to drive the drive shaft 21 and the driving bevel gear 22 to rotate forward, the driving bevel gear 22 drives the driven bevel gear 23, the connecting rod 19 and the two lead screws 17 to rotate forward, so that the two transverse sliders 4 slide away from each other, and the distance between the two bearing plates 5 can be controlled to gradually increase. Similarly, by controlling the motor 20 to drive the drive shaft 21 and the driving bevel gear 22 to rotate in reverse, the two transverse sliders 4 can be made to slide towards each other, and the distance between the two bearing plates 5 can be controlled to gradually decrease. After adjusting the distance between the two bearing plates 5 to be appropriate according to the length dimension of the PAN fiber integrated felt, stop the motor 20. Then take two edge tapes with appropriate widths cut in advance (the material of the edge tape can be the same as that of the PAN fiber integrated felt) and wrap them around the symmetric two side parts of the PAN fiber integrated felt respectively. Then place the PAN fiber integrated felt between the two bearing plates 5 on the platform, so that the two side parts of the PAN fiber integrated felt wrapped with the edge tapes respectively pass through the corresponding U-shaped frames 12 and are laid flat on the corresponding bearing plates 5, and the two side parts wrapped with the edge tapes are respectively located directly below the corresponding sewing needles 11.

Then control the two electric sliders 8 to move longitudinally in a straight line on the corresponding electric guide rails 7 and control the two sewing machines 10 to operate. The two electric sliders 8 respectively drive the sewing machines 10 installed thereon to move longitudinally in a straight line. Under the joint action of the two sewing needles 11, the two side parts of the PAN fiber integrated felt can be automatically sewn and sealed simultaneously. After the sewing and sealing of the two side parts of the PAN fiber integrated felt are completed, stop the operation of the two sewing machines 10 and the two electric sliders 8. By controlling the two electric telescopic rods 13 to contract and reset, the pressing and fixing of the PAN fiber integrated felt can be released. Then adjust the position of the PAN fiber integrated felt. According to the above operation steps, the sewing and sealing of the other two side parts of the PAN fiber integrated felt can be carried out simultaneously.
