Description

Technical Field

[0001] The invention relates to the field of ETFE films, and in particular to a high-efficiency stretching molding process and equipment for an ETFE film structure. Background Art

[0002] ETFE membrane structure is a very light and tough advanced material composed of ETFE membrane material and steel structure. Compared with traditional building materials, ETFE membrane structure has the advantages of high light transmittance, light weight, high strength and long service life. At the same time, ETFE membrane structure can be opened without restriction and does not need to be fixed in a specific range by supporting structure. Even the worst weather will not affect its performance. However, the existing ETFE membrane needs to be stretched and formed during production and installation. The existing stretching method usually clamps the two ends of the ETFE membrane through a clamping component and then directly stretches the ETFE membrane. This method is difficult to stretch the ETFE membrane and can only be stretched once, resulting in large stretching equipment and a single function of the forming device. The stretched ETFE membrane is uneven.

[0003] For example, the Chinese utility model patent (application number: CN202020707772.X) discloses a "tensioning device used when installing an ETFE membrane structure". Its specification discloses that the composition of the ETFE membrane material is ethylene-tetrafluoroethylene copolymer, which is a transparent membrane material without a fabric substrate, and its elongation can reach 420% to 440%. The light transmittance spectrum of the ETFE membrane material is similar to that of glass (commonly known as soft glass), and is suitable for building roofs or walls of building spaces that require sufficient indoor sunlight. The ETFE membrane material allows large elastic deformation, but creep extension will occur, so it is not suitable for the spatial membrane surface of the tensioned structural system with resistance requirements. When installing some ETFE membranes used in buildings, a single-layer tensioning method is adopted, which is similar to the general fabric membrane structure. During construction, the tensioning film tightens the membrane surface to complete the installation. The ETFE membrane used in buildings is large in size and difficult to tension; the above patents can prove the defects of the prior art.

[0004] Therefore, we made improvements and proposed an efficient stretching forming process and equipment for ETFE membrane structure. Summary of the invention

At this time, the rotation of the worm 402 drives the threaded rod 405 to rotate.

[0039] The drive assembly 4 is provided to facilitate the rotation of the adjustment assembly 5 and also facilitate the movement of the movable assembly 3 .

[0040] Further, such as Figure 3 , Figure 4 and Figure 5As shown, the movable component 3 includes a second clamping block 301, and the second clamping block 301 is symmetrically distributed with the first clamping block 201.

At this time, the connecting handle 604 moves downward and drives the tool holder 601 to rotate downward under the damping of the damper 605.

[0045] The tool holder 601 disposed inside the cutting assembly 6 facilitates the cutting of the ETFE film by cooperating with the adjusting assembly 5 when cutting is required. At the same time, the ETFE film can be squeezed and fixed through its top during stretching. A groove corresponding to the cutting assembly 6 is provided inside the first clamping block 201, thereby facilitating the rotation of the tool holder 601.

[0046] The use process of the ETFE membrane structure high-efficiency stretching forming process and equipment provided by the present invention is as follows: First, take out the device and place it in a proper position, take out the ETFE film to be stretched, pass it through the first clamping block 201 in sequence, and wind it back to the first clamping block 201 along the second tensioning wheel 311 and the second clamping block 301 and the first tensioning wheel 202; At this point, the ETFE film is fixed. At this time, the stretching force required is determined according to the ETFE film that needs to be stretched, and the elliptical plate 305 is rotated to drive the movable shaft 306 to compress the adjustment spring 308, thereby limiting the second tensioning wheel 311, so that when the driving motor 401 outputs the same power, the tensile strength of the ETFE film is adjusted until the adjustment is completed, and under the limitation of the baffle 303 and the spring 304, the elliptical plate 305 is fixed, and the driving motor 401 is started at this time, and the threaded rod 405 is driven to rotate by the driving motor 401 and the worm 402, the sleeve block 403 and the clamping block 406 installed at its output end, thereby pushing the second clamping block 301 to move, and then the second clamping block 301 cooperates with the second clamping block 301 to move. The second tensioning wheel 311 drives the ETFE film to stretch until it is stretched to an appropriate position, at which time the electric push rod 506 can be started, and the electric push rod 506 pushes the transmission rod 504 to move through the right-angle rod 505 and the gear plate 503, and then the threaded rod 405 is moved downward under the drive of the transmission rod 504, so that the sleeve block 403 and the clamping block 406 are separated, and the gear plate 503 is also separated from the spur gear 502. At this time, the drive motor 401 is started to drive the rotating roller 501 to rotate through the worm 402 and the turbine 404, and then the stretched ETFE film is transported by manual labor until it is transported to an appropriate position, and then the electric push rod 506 is started in the reverse direction, and the above steps are repeated to achieve continuous stretching operation; If the stretching is completed and the ETFE film needs to be rolled and cut, the drive motor 401 can be started in reverse to make the first clamping block 201 and the second clamping block 301 approach each other, and the ETFE film to be cut is taken out, and the above winding steps are repeated. The first clamping block 201 and the second clamping block 301 cooperate with the first tensioning wheel 202 and the second tensioning wheel 311 to squeeze and clamp the first clamping block 201 and the second clamping block 301. At this time, the above steps are repeated to separate the sleeve block 403 from the clamping block 406, and the electric push rod 506 is continuously started to make the gear in the middle of the gear plate 503 mesh with the spur gear 502. At this time, the drive motor is started The machine 401 drives the motor 401 to convey the first clamping block 201 and the second clamping block 301 through the rotating roller 501, so as to cooperate with the first clamping block 201 and the second clamping block 301 to achieve rolling. At this time, the gear plate 503 continues to rotate, and drives the right-angle rod 505 installed at the other end of the gear plate 503 to rotate until the gear plate 503 rotates one circle. At this time, the right-angle rod 505 contacts and squeezes the top of the connecting handle 604, and then drives the tool holder 601 hinged to the first clamping block 201 to rotate downward under the buffering of the damper 605, so as to cut the ETFE film. This reciprocating process can achieve equidistant cutting of the ETFE film. At the same time, the electric push rod 506 can cooperate with the gear plate 503, and under the limit of the limit block 507, the outermost gear of the gear plate 503 is meshed with the spur gear 502. At this time, the above steps are repeated to change the cutting width of the ETFE film.
