DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-6 As shown, a multi-lane film laying device includes a base 1, a support mechanism 3 is arranged on the upper part of the base 1, a plurality of film rolls 6 are arranged in the middle of the support mechanism 3, an adjustment mechanism 7 is arranged in the middle of the support mechanism 3, and a cutting mechanism 4 and a rewinding mechanism 5 are arranged at the lower part of one side of the support mechanism 3.

[0024] In this embodiment, the support mechanism 3 includes two support plates 301, multiple straight slide grooves 302, multiple limit rods 303, two toothed discs 304, multiple arc slide grooves 305, gears 306, transmission rods 307, reduction motors 308 and two protective shells 309. The limit rods 303 are slidably connected to the straight slide grooves 302 and the arc slide grooves 305 on the left and right sides. Multiple straight slide grooves 302 are opened on the upper part of the support plate 301, and multiple arc slide grooves 305 are opened in the middle of the toothed disc 304. The middle part of the gear 306 is fixedly connected to the left and right ends of the transmission rod 307. The middle part of the gear 306 is rotatably connected to the upper part of the support plate 301. The toothed disc 304 and the gear 306 are meshed with each other. One side of the protective shell 309 is fixedly connected to the outer side of the support plate 301, and the protective shell 309 is sleeved on the outer periphery of the toothed disc 304 and the gear 306. The reduction motor 308 is installed therein On the outside of a protective shell 309, the output end of the reduction motor 308 is fixedly connected to the middle of the gear 306, and a plurality of rollers 2 are arranged at the lower part of the base 1. The unwinding mechanism 5 includes a servo motor 501, an auxiliary roller 502 and a conveying roller 503. The left and right ends of the conveying roller 503 and the auxiliary roller 502 are arranged at the lower part of one side of the support mechanism 3. The servo motor 501 is installed on the outside of the support mechanism 3, and the output end of the servo motor 501 is fixedly connected to one end of the auxiliary roller 502. The cutting mechanism 4 includes an electric push rod 401, a heating wire 402 and a support rod 403. One end of the support rod 403 is fixedly connected to the left and right ends of the heating wire 402, and the other end of the support rod 403 is rotatably connected to one side of the lower part of the support mechanism 3. One end of the electric push rod 401 is rotatably connected to the middle of the support rod 403, and the other end of the electric push rod 401 is rotatably connected to the lower part of the support mechanism 3.

[0025] Specifically, since the limit rod 303 can slide inside the straight slide groove 302, it drives the reduction motor 308, and the two gears 306 rotate through the transmission rod 307, thereby driving the toothed disc 304 to rotate, and then driving the limit rod 303 to slide inside the straight slide groove 302 through the arc slide groove 305, so that multiple limit rods 303 move inward or outward at the same time, so that the limit rod 303 can always fit the outer periphery of the film roll 6, limit the film roll 6 to the middle of the support mechanism 3, and can be suitable for film rolls 6 of various diameters. The film roll 6 passes between the auxiliary roller 502 and the conveying roller 503, and the servo motor 501 is driven to rotate the auxiliary roller 502 to discharge the material. When the film laying is completed, the heating wire 402 is energized to increase the temperature of the heating wire 402, drive the electric push rod 401 to extend or shorten, and make the support rod 403 move up and down, thereby cutting the film roll 6.

[0026] In this embodiment, the adjustment mechanism 7 includes a servo motor 2 701, a belt 702, two pulleys 703, a threaded rod 704 and a partition 705. The left and right ends of the threaded rod 704 are rotatably connected to the lower part of the support plate 301, the lower part of the partition 705 is threadedly connected to the outer periphery of the threaded rod 704, and the middle part of the partition 705 is slidably connected to the outer periphery of the limit rod 303. The middle part of one of the pulleys 703 is fixedly connected to one end of the threaded rod 704, and the middle part of the other pulley 703 is fixedly connected to the output end of the servo motor 2 701. The servo motor 2 701 is installed on the upper part of the base 1, and the belt 702 is internally meshed and connected to the outer periphery of the pulley 703. The outer thread spacing of the threaded rod 704 is twice the middle thread spacing.

[0027] Specifically, the servo motor 2 701 is driven to rotate the threaded rod 704 through the belt 702 and the pulley 703. Since the partition 705 is restricted by the limit rod 303 and cannot rotate, when the threaded rod 704 rotates, the partition 705 will move, thereby adjusting the distance between the partition 705 and the support plate 301 or the partition 705, so as to adapt to the use of film rolls 6 of different widths.

[0028] Working principle:

[0029] Since the limiting rod 303 can slide inside the straight slide groove 302, the reduction motor 308 is driven to rotate the two gears 306 through the transmission rod 307, thereby driving the toothed disc 304 to rotate, and then driving the limiting rod 303 to slide inside the straight slide groove 302 through the arc slide groove 305, so that multiple limiting rods 303 move inward or outward at the same time, so that the limiting rod 303 can always fit the outer periphery of the film roll 6, limit the film roll 6 to the middle of the support mechanism 3, and can be suitable for film rolls 6 of various diameters, drive the servo motor 2 701, and drive the threaded rod 704 to rotate through the belt 702 and the pulley 703, and then the limiting rod 303 can be driven to slide inside the straight slide groove 302 through the arc slide groove 305, so that multiple limiting rods 303 can move inward or outward at the same time, so that the limiting rod 303 can always fit the outer periphery of the film roll 6, limit the film roll 6 to the middle of the support mechanism 3, and can be suitable for film rolls 6 of various diameters, drive the servo motor 2 701, and drive the threaded rod 704 to rotate through the belt 702 and the pulley 703, and then the limiting rod 303 can be driven to slide inside the straight slide groove 302 through the arc slide groove 305, so that the limiting rod 303 can be driven to slide inward or outward at the same time, so that the limiting rod 303 can always fit the outer periphery of the film roll 6, limit the film roll 6 to the middle of the support mechanism 3, and can be suitable for film rolls 6 of various diameters, drive the servo motor 2 701, and drive the threaded rod 704 to rotate through the belt 702 and the pulley 70 The partition 705 is restricted by the limit rod 303 and cannot rotate. Therefore, when the threaded rod 704 rotates, the partition 705 will move, thereby adjusting the distance between the partition 705 and the support plate 301 or the partition 705, so as to adapt to film rolls 6 of different widths. The film roll 6 is passed between the auxiliary roller 502 and the conveying roller 503, and the servo motor 501 is driven to rotate the auxiliary roller 502 to discharge the material. When the film laying is completed, the heating wire 402 is energized to increase the temperature of the heating wire 402, driving the electric push rod 401 to extend or shorten, so that the support rod 403 moves up and down, and then the film roll 6 is cut.
