Description

Technical Field

[0001] This utility model relates to the field of Teflon fabric production and processing technology, specifically an automatic Teflon fabric rolling and folding device. Background Technology

[0002] Teflon cloth, scientifically known as polytetrafluoroethylene coated fiberglass cloth, is a composite material made of high-performance fiberglass cloth as the base material and uniformly coated with PTFE resin. Its core characteristics stem from the "king of plastics" properties of PTFE and the high-strength support of fiberglass, earning it the reputation of an "industrial all-rounder" material, and it is widely used in demanding environments such as high temperature, corrosion, and clean environments.

[0003] The "rolling and folding" of Teflon cloth is not the core link in its raw material production (substrate coating and sintering), but a key process connecting the finished Teflon cloth processing with downstream applications. It directly determines whether Teflon cloth can be transformed from "wide-width master cloth" into "customized products that can be used on the ground", and has irreplaceable significance for the integrity, efficiency and market adaptability of its production chain.

[0004] When folding Teflon fabric, it is usually done by a winding machine. At the beginning of the winding process, the front end of the Teflon fabric needs to be manually fixed. It can only be automatically folded after the winding roller has rotated once. This process is not only dangerous but also quite troublesome. Another method is to use adhesive to fix the end of the Teflon fabric. Although this method does not require manual labor, it requires glue for each fold. As the workload increases, the amount of glue consumed also increases, resulting in a corresponding increase in cost. Utility Model Content

[0024] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0025] This utility model provides an improved automatic Teflon fabric rolling and folding device. The technical solution of this utility model is as follows:

[0026] like Figure 1 - Figure 4 As shown, an automatic Teflon fabric rolling device includes a base 1, which is a rectangular worktable. A base frame 2 is fixedly connected to the top of the base 1. The base frame 2 is composed of a rectangular rod in the lower half and a disc in the upper half. A servo motor is installed on one side wall of the base frame 2. The servo motor is electrically connected to a corresponding power supply. This is existing technology and will not be described in detail here.

[0027] like Figures 1-4As shown, a roll-up structure is installed on the side wall of the disc of the base frame 2 for rolling up Teflon fabric. The roll-up structure includes: a take-up shaft 3, an inlet groove 5, a slot 6, a rotating shaft 7, and a clamping plate 10. The take-up shaft 3 is rotatably connected to the side wall of the disc of the base frame 2. The inlet groove 5 is opened above the take-up shaft 3. The slot 6 is opened in the inlet groove 5. The rotating shaft 7 is rotatably connected in the inlet groove 5. The clamping plate 10 is fixedly connected to the outer wall of the rotating shaft 7.

[0028] like Figures 1-4 As shown, the inlet groove 5 is a capsule-shaped groove, the take-up shaft 3 is cylindrical, the inlet groove 5 is located on top of the take-up shaft 3, and the slot 6 is located on the wall of the take-up shaft 3 behind the inlet groove 5. The inlet groove 5 can communicate with the slot 6. The slot 6 is an arc-shaped groove, and the top of the inlet groove 5 is open. The position of the take-up shaft 3 is opposite to the servo motor. The servo motor is fixedly connected to the side wall of the take-up shaft 3 through a shaft connector. The rotating shaft 7 is rotatably connected inside the inlet groove 5. The clamping plate 10 is located on top of the rotating shaft 7. The clamping plate 10 is a rod with an inverted L-shaped cross section, and the corner of the clamping plate 10 faces the slot 6. The rotating shaft 7 is a column with an elliptical cross section. The slot 6 and the outer side of the inlet groove 5 are open. The winding structure also includes an anti-slip rod 4, an adapter 8, an adsorption strip 9, and an anti-detachment rod 11. The anti-slip rod 4 is fixedly connected to... The anti-slip rod 4 is a rectangular rod attached to the bottom arc surface of the take-up shaft 3. Multiple identical anti-slip rods 4 are evenly arranged on the bottom arc surface of the take-up shaft 3. The adapter 8 is fixedly connected to one side of the rotating shaft 7. The adapter 8 is composed of a cylinder and a disc. The cylinder of the adapter 8 can pass through the side wall of the take-up shaft 3. The rotating shaft 7 rotates on the wall of the take-up shaft 3 through the adapter 8. The bottom of the adsorption strip 9 can always be in contact with the wall inside the inlet groove 5. A rectangular strip-shaped magnetic strip is fixedly connected to the bottom of the inlet groove 5. The adsorption strip 9 is fixedly connected to the rear wall of the rotating shaft 7. The magnetic strip can be attracted to the wall of the adsorption strip 9. The anti-detachment rod 11 is fixedly connected to the rear wall of the card plate 10. The anti-detachment rod 11 is a rod with a semi-circular cross section. Multiple identical anti-detachment rods 11 are arranged longitudinally on the rear wall of the card plate 10.

[0029] In practical use, firstly, the front end of the Teflon cloth is directly inserted into the slot 6 through the opening above the inlet 5. Then, the servo motor controls the take-up shaft 3 to rotate counterclockwise rapidly. As the take-up shaft 3 rotates, it drives the card plate 10 and the card plate 10 to swing synchronously within the inlet 5 around the adapter 8. When the rotating shaft 7 rotates, it drives the suction strip 9 to rotate synchronously. The suction strip 9 moves towards the magnetic strip in the inlet 5 due to the swinging motion of the rotating shaft 7. When the card plate 10 swings, it causes the anti-detachment rod 11 to contact the wall of the Teflon cloth. The Teflon cloth is stuck between the opening above the inlet groove 5 and the anti-detachment rod 11. At this time, as the winding shaft 3 gradually rotates, the Teflon cloth will be wound on the outer wall of the winding shaft 3. After the Teflon cloth is wound on the outer wall of the winding shaft 3, the unloading structure can push the wound Teflon cloth roll toward the side wall opening of the inlet groove 5 to unload it. The rotation process of the upper rotating shaft 7 and the clamping plate 10 is achieved when the weight of the wound Teflon cloth is relatively light. When the weight of the Teflon cloth is relatively heavy, the clamping plate 10 and the rotating shaft 7 will be blocked by the Teflon cloth.

[0030] In summary, by setting up a pull-roll structure and using the folded-back end of the Teflon fabric to achieve temporary fixation of the Teflon fabric, the need for manual support by workers and the elimination of the need for glue for auxiliary winding are eliminated. This not only ensures the safety of workers but also saves on winding costs.

[0031] like Figures 1-4 As shown, the outer wall of the base frame 2 is provided with an unloading structure, which includes a fixed plate 12, an electric cylinder 13, a push plate 14 and a trough 15. The fixed plate 12 is fixedly connected to the side wall of the base frame 2 on the same side as the servo motor. The fixed plate 12 is located above the servo motor. The electric cylinder 13 is fixedly connected to the top of the fixed plate 12. The push plate 14 is fixedly connected to the telescopic end of the electric cylinder 13. The trough 15 is opened through the side wall of the push plate 14. The push plate 14 is a plate with an inverted L-shaped cross section. The trough 15 is located on the side plane of the push plate 14. The trough 15 is circular. The position of the winding shaft 3 can be aligned with the center of the trough 15. The side wall of the corner of the push plate 14 can contact and fit with the corresponding side wall of the base frame 2.

[0032] In practical use, after the Teflon cloth is wound up, the electric cylinder 13 is extended. When the electric cylinder 13 extends, it pushes the push plate 14 to move. The push plate 14 will gradually separate from the side wall of the base frame 2. Then the other side wall of the push plate 14 will come into contact with the side wall of the wound Teflon cloth, thereby pushing it away from the outer wall of the winding shaft 3. It should be noted that before pushing the wound Teflon cloth, its rear end needs to be fixed to prevent it from falling.

[0033] In summary, by setting up an unloading structure, the Teflon cloth can be automatically unloaded from the wall of the winding shaft 3 after winding, saving manual unloading while also having a stable unloading efficiency.

[0034] Working principle: The front end of the Teflon cloth is directly inserted into the slot 6 through the opening above the inlet 5. Then, the servo motor controls the take-up shaft 3 to rotate counterclockwise rapidly. As the take-up shaft 3 rotates, it drives the clamping plate 10 to swing synchronously around the adapter 8 in the inlet 5. When the rotating shaft 7 rotates, it drives the adsorption strip 9 to rotate synchronously. The adsorption strip 9 moves towards the magnetic strip in the inlet 5 due to the swinging of the rotating shaft 7. When the clamping plate 10 swings, it drives the anti-detachment rod 11 to contact the wall of the Teflon cloth, so that the Teflon cloth is stuck between the opening above the inlet 5 and the anti-detachment rod 11. At this time, as the take-up shaft 3 gradually rotates, the Teflon cloth will be wound up on the outer wall of the take-up shaft 3. After the Teflon cloth is wound up on the outer wall of the take-up shaft 3, it can be pushed towards the side wall opening of the inlet 5 through the unloading structure to unload.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this invention. Therefore, this invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
