[0077] Example 3

[0078] The ETFE film hot-melt production equipment provided in Example 1 or 2 is further optimized, specifically, as Figure 1 , Figure 4 and Figure 6 As shown, the pressing assembly 9 includes two connecting plates 909 symmetrically and evenly distributed and movably installed on the outer wall of the threaded rod 513. The threaded rod 513 is used as the axis to cooperate with the connecting plate 909 to rotate. One end of the connecting plate 909 is fixedly connected to a torsion spring plate 901, and one side of one torsion spring plate 901 is movably connected to a third rotating frame 902. The other end of the third rotating frame 902 is movably connected to an auxiliary telescopic rod 903, and the other end of the auxiliary telescopic rod 903 is movably connected to a fourth rotating frame. The other end of the fourth rotating frame is movably installed on the outer wall of the auxiliary shaft 602. A round rod 910 is fixedly connected between the two connecting plates 909. The auxiliary shaft 602 is displaced, and the auxiliary telescopic rod 903 cooperates with it to stretch.

[0081] Example 4

[0082] The ETFE film hot-melt production equipment provided in embodiment 1, 2 or 3 is further optimized, specifically, as Figure 1 , Figure 4 , Figure 5 and Figure 7The cooling component 8 includes a fixed shaft 801 fixedly installed in the middle of the clamping frame 604, and the outer wall of the fixed shaft 801 is evenly distributed in a straight line and fixedly connected with a plurality of elastic hinges 804, and the outer wall of the elastic hinge 804 is fixedly connected with a dial plate 805, which is driven by multiple elastic hinges 804 to reciprocate (compared with a single dial plate 805, the reciprocating time of a single elastic hinge 804 is longer), so as to ensure the cooling effect, and the upper clamping plate 605 in the clamping frame 604 rotates with the auxiliary shaft 602, so that the dial plate 805 rotates around the fixed shaft 801 and compresses the elastic hinge 804, and when the dial plate 805 is downward, the upper clamping plate 605 in the clamping frame 604 When the pulley 603 rotates downward, the auxiliary plate 806 is pushed and rotated around the fixed axis 801, so as to further clamp and position the ETFE film. When the pulley 603 returns to its original position, the upper clamping plate 605 and the lower clamping plate 609 are unfolded, and the elastic hinge 804 releases elastic potential energy, which drives the paddle plate 805 to rotate back and forth around the fixed axis 801 to generate airflow. After the auxiliary plate 806 loses the pressure of the upper clamping plate 605, the auxiliary plate 806 rotates around the shaft 802 to generate airflow synchronously. The airflow generated at this time blows the surface of the welded part of the ETFE film (although the airflow is small, too large an airflow can easily cause the welded part to break, thereby affecting the welding effect).

[0083] Through the elastic structure of the elastic hinge 804, the ETFE film is further positioned and clamped during the welding process. When the welding is completed and the ETFE film is released, the elastic potential energy released by the elastic hinge 804 drives the paddle 805 to rotate back and forth, so as to cool the welded part of the ETFE film, thereby fanning and cooling the welded part of the ETFE film to ensure the effect of the cooling treatment.

[0084] Further, such as Figure 4 , Figure 5 and Figure 7 As shown, a lower clamping plate 609 is fixedly connected to the lower part of the outer wall of the auxiliary shaft 602, a shaft rod 802 is fixedly connected in the middle of the lower clamping plate 609, an auxiliary plate 806 is movably connected to the outer wall of the shaft rod 802, a convex plate 803 is fixedly connected to the upper part of the auxiliary plate 806, and the convex plate 803 is installed on the auxiliary plate 806, so as to assist in positioning the ETFE film when the dial plate 805 contacts it, and a pressure plate 807 is fixedly connected to the auxiliary plate 806 at one end close to the auxiliary shaft 602, and the upper clamping plate 605 during the downward movement of the clamp frame 604 presses the pressure plate 807 connected to the auxiliary plate 806, so that it rotates around the shaft rod 802 and fits with the dial plate 805, so as to further clamp and position the ETFE film.

[0085] Example 5

[0086] The ETFE film hot-melt production equipment provided in embodiment 1, 2, 3 or 4 is further optimized, specifically, as Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The cutting and cleaning assembly 7 includes two curved disc rods 701 symmetrically and evenly distributed and movably installed on the outer wall of the threaded rod 513, one end of the two curved disc rods 701 is fixedly connected to a positioning frame 704, and a plurality of spring telescopic rods 705 are movably connected to the lower inner wall of the positioning frame 704 in a straight line and evenly distributed, and a slide plate 707 is fixedly connected below the plurality of spring telescopic rods 705, and a knife plate 708 is fixedly connected below the slide plate 707, and a knife groove 709 is movably connected below the knife plate 708, and a positive arc knife 710 is fixedly connected to the side of the knife plate 708, and a reverse arc knife 711 is fixedly connected to the side of the knife groove 709. Due to the arc design of the positive arc knife 710 and the reverse arc knife 711, the upper surface and the lower surface of the ETFE film are in close contact, thereby ensuring the quality of cleaning. The winding roller 3 rotates continuously, and the upper surface and the lower surface of the ETFE film contact the positive arc knife 710 and the reverse arc knife 711 respectively. Under the continuous movement of the ETFE film, the residue on the surface of the ETFE film is cleaned. When cutting and welding are required, the electric telescopic rod 703 needs to be started to move, so that one of the curved disc rods 701 is pushed. With the cooperation of the threaded rod 513, the other end of the curved disc rod 701 moves downward, driving the knife plate 708 to contact the knife groove 709, and cutting it. Therefore, the surface of the ETFE film can be cleaned during the winding process, and the ETFE film in the welding process can be cut, thereby improving the convenience of the ETFE film winding and welding process.

[0087] Further, such as Figure 3 and Figure 4 As shown, two slide plates 706 are symmetrically and evenly distributed and fixedly connected to the bottom of the positioning frame 704. The two slide plates 706 are movably connected to the slide plate 707. The stability of the knife plate 708 during the descending process is ensured through the movable connection between the slide plate 706 and the slide plate 707. One of the curved disk rods 701 is movably connected to the side of the positioning rod 702, and the other end of the positioning rod 702 is movably connected to the electric telescopic rod 703. The other end of the electric telescopic rod 703 is movably mounted on the outer wall of the auxiliary shaft 602.

[0089] The ETFE film hot-melt production equipment provided in embodiment 1, 2, 3, 4 or 5 is further optimized, specifically, as Figure 1 and Figure 3 The outer wall of the threaded rod 513 is movably connected with a filling component 10, and the filling component 10 includes a threaded frame plate 1001 movably installed on the outer wall of the threaded rod 513, one end of the threaded frame plate 1001 is fixedly connected with a plate body 1004, a nozzle 1002 is fixedly connected in the middle of the plate body 1004, and a conduit 1003 is fixedly connected above the nozzle head 1002. Both sides of the plate body 1004 are fixedly connected with inclined plates 1005, and the inclined plates 1005 are obliquely connected to the plate body 1004 so that the hot-melt material can be evenly scraped. Driven by the pressing component 9, the threaded frame plate 1001 rotates downward so that the inclined plates 1005 synchronously press the two sections of ETFE film into the auxiliary groove plate 907, and then the threaded frame plate 1001 is driven to move under the rotation of the threaded rod 513, and at the same time, the fusion material is introduced into the nozzle 1002 by the conduit 1003 and evenly sprayed to the fusion joint of the two sections of ETFE film.

[0090] The use process of the ETFE film hot-melt production equipment provided by the present invention is as follows:

[0091] Working principle: The staff first passes the ETFE film between the positive arc knife 710 and the reverse arc knife 711, then passes between the upper clamping plate 605 and the lower clamping plate 609, and then passes under the pressing roller 606, goes around the auxiliary roller 14, and contacts the winding roller 3. Then the servo motor 507 is started to drive the positioning wheel 506 to rotate. With the cooperation of the transmission belt 505, the auxiliary wheel 504 follows the rotation, providing power for the rotation of the auxiliary gear 502. At this time, the rotating auxiliary gear 502 drives the positioning gear 501 to rotate, so that the winding roller 3 follows the rotation, so as to perform the winding operation. During the winding process, the winding roller 3 keeps rotating, and the upper and lower surfaces of the ETFE film are in contact with the positive arc knife 710 and the reverse arc knife 711 respectively. Under the continuous movement of the ETFE film, the residue on the surface of the ETFE film is cleaned. Before the welding operation is required, the electric telescopic rod 703 needs to be started to move, so that one of the crank rods 701 is pushed. Under the cooperation of the threaded rod 513, the other end of the crank rod 701 moves downward, driving the knife plate 708 to contact the knife groove 709, and cutting it. The neatly cut ETFE film is continued to be pulled and moved to a suitable position. Then, the hydraulic telescopic rod 509 is started. Under the cooperation of the first rotating frame 508 and the second rotating frame 510, the support rod 503 is rotated with the rotating shaft of the servo motor 507 as the central axis, thereby driving the auxiliary gear 502 to disengage from the positioning gear 501 and mesh with the fixed gear 512. When the support rod 503 rotates, the connecting rod 511 is driven to push the pulley 603, and the pulley 603 moves in the curved groove plate 601. The auxiliary shaft 602 drives the upper clamping plate 605 and the lower clamping plate 609 to move to one side. Due to the height difference between the two ends of the curved groove plate 601, the clamping frame 604 rotates around the auxiliary shaft 602 during the movement, thereby driving the upper clamping plate 605 to move, and cooperating with the upper clamping plate 605 to clamp and move the ETFE film, so that one end of the ETFE film is in the auxiliary groove plate 907. In the clamping process, the upper clamping plate 605 in the clamping frame 604 rotates with the auxiliary shaft 602, so that the dial plate 805 rotates around the fixed shaft 801, and The elastic hinge 804 is compressed. When the dial plate 805 moves downward, the upper clamping plate 605 in the clamping frame 604 rotates downward, pushing the auxiliary plate 806 and rotating around the fixed axis 801, so as to further clamp and position the ETFE film. During the clamping and transmission process, another section of the ETFE film to be welded is placed in the auxiliary slot plate 907, and the auxiliary axis 602 is displaced, and the auxiliary telescopic rod 903 cooperates with it to stretch. With the cooperation of the third rotating frame 902 and the fourth rotating frame, after the stretching reaches the maximum length, the pressing rod 905 is pulled, and the torsion spring plate 901 is pulled, driving the pressing rod 905 to move downward, and the two sections of ETFE film in the auxiliary slot plate 907 are pressed and positioned.The inclined plate 1005 at one end of the threaded frame plate 1001 is driven to contact the auxiliary groove plate 907. At this time, the auxiliary gear 502 provides power for the meshing fixed gear 512, driving the threaded rod 513 to rotate. Under the rotation of the threaded rod 513, the threaded frame plate 1001 is driven to move. At the same time, the welding material is introduced into the nozzle 1002 by the conduit 1003 and sprayed evenly to the welding point of the two sections of ETFE film. After the welding is completed, the pulley 603 is driven by the hydraulic telescopic rod 509 to reset the upper clamping plate 605 and the lower clamping plate 609 are unfolded. The elastic hinge 804 releases its elastic potential energy, driving the paddle plate 805 to rotate back and forth around the fixed shaft 801, generating airflow. After the auxiliary plate 806 loses the pressure of the upper clamping plate 605, the auxiliary plate 806 rotates around the shaft 802, generating airflow synchronously. The airflow generated at this time blows the surface of the ETFE film welded part, and the material at the welded part gradually cools down. The pressing rod is also driven by the pulley 603 to move away from the auxiliary groove plate 907, and the auxiliary gear 502 is meshed with the positioning gear 501 again, so as to perform the winding operation.
