DETAILED DESCRIPTION

[0028] See also Figure 1-Figure 4 In an embodiment of the present invention, a film conveying device comprises a symmetrically arranged bracket 1, and a horizontal mounting frame 2 is slidably connected to the opposite sides of the two brackets 1, and the horizontal mounting frame 2 can be vertically slidably arranged on the bracket 1, and a lifting motor 21 for driving the horizontal mounting frame 2 to move vertically on the bracket 1 is provided on one side of the bracket 1. Preferably, sprockets are distributed in the vertical direction of the bracket 1, and the outer transmission link of the sprocket is connected with a chain, and the horizontal mounting frame 2 is installed on the chain, so that the lifting motor 21 drives the sprocket and the chain to rotate, and can drive the horizontal mounting frame 2 to move vertically; similarly, the transmission can also be realized by using the screw slider. The horizontal mounting frame 2 is rotatably connected to multiple groups of parallel conveying rollers 22, and the conveying rollers 22 are synchronously driven by chains or belts. A conveying motor 23 for driving the conveying roller 22 to rotate is provided on one side of the conveying roller 22, and the conveying rollers 22 on both sides can be synchronously driven by shafts. The conveying roller 22 is provided with a bottom plate 3, and the two sides of the horizontal placement frame 2 are symmetrically fixedly connected with guide rail grooves sleeved on the outer side of the edge of the bottom plate 3. After starting the conveying motor 23, the bottom plate 3 can be driven to move along the guide rail groove by the conveying roller 22. A placement mechanism for placing a film is installed on the bottom plate 3. Starting the lifting motor 21 can drive the horizontal placement frame 2, thereby driving the placement mechanism on the bottom plate 3 to adjust the placement height. Starting the conveying motor 23 can drive the conveying roller 22 to rotate, thereby driving the bottom plate 3 to move along the guide rail groove through the conveying roller 22. The placement mechanism includes a placement frame plate 31 symmetrically arranged on the bottom plate 3, and the placement frame plate 31 is rotatably connected with a side stop rotating plate 32, and a winding shaft 33 is fixedly connected between the side stop rotating plates 32 on both sides, and one end of the winding shaft 33 is transmission-connected with a one-way transmission component.

[0029] When in use, the height of the bottom plate 3 and the distance relative to the use process are adjusted as needed, and the one-way transmission component is started to drive the winding shaft 33 to rotate to achieve film winding. The operation is simple and convenient, and the position is easy to adjust. When the film needs to be used, the end of the film is pulled, and the one-way transmission component is separated from the pulling of the winding shaft 33, which will not affect the release of the film. The overall placement is stable and convenient, and the film winding and releasing are convenient.

[0030] Among them, Figure 4 As shown, the placement frame plates 31 are also connected to multiple sets of guide shafts 34 of different heights. The film is wound around the winding shaft 33, and its free end is sequentially wound around the periphery of the guide shaft 34. The film surface can be tightened by the adjacent guide shafts 34 to keep the film surface flat for transportation. At the same time, the guide shafts 34 of different heights can also prevent the end of the film from falling off. Preferably, the position of the guide shaft 34 can also be set to be adjustable, so as to facilitate adjustment according to needs.

[0031] like Figure 5-Figure 8 As shown, the outer periphery of the end of the winding shaft 33 is fixedly connected with a ratchet 3301, the outer side of the mounting frame 31 is installed with a winding motor 36, the output end of the winding motor 36 is fixedly connected with a one-way transmission component connected to the ratchet 3301 for one-way transmission, the middle part of the side stop plate 32 is provided with a through hole 3201 for the winding shaft 33 to pass through, the side stop plate 32 is provided with an internal gear 3202 on the edge of the side stop plate 32 facing the winding motor 36, and the one-way transmission component and the internal gear 3202 are adapted to each other. When in use, when the one-way transmission component is driven to rotate by the winding motor 36 to cooperate with the ratchet 3301 to drive the winding shaft 33 to rotate the winding film, it can also be synchronized with the internal gear 3202 to synchronize with the rotation of the side stop plate 32, so as to drive the side stop plate 32 to rotate synchronously, so as to improve the stability during winding. When the film is large in weight, the winding resistance will not affect the driving effect of the winding motor 36.

[0032] Among them, the one-way transmission component includes an annular cover 3601 fixedly connected to the output end of the winding motor 36, and the annular cover 3601 is concentrically covered on the outer periphery of the ratchet 3301 toward the side of the side baffle plate 32, and multiple groups of elastic rods 3602 are slidingly penetrated at the edge of the annular cover 3601, and the end of the elastic rod 3602 facing the inner gear 3202 is fixedly connected with a latch tooth 3604 corresponding to the inner gear 3202 and meshing with the inner gear 3202, and the inner gear 3202 is rotatably connected with a latch plate 3603 corresponding to the ratchet 3301 and snap-fitting. Preferably, four elastic rods 3602 are distributed in a cross array with the center of the circle around the reel 33 as the origin, a spring is connected between the elastic rod 3602 and the ring cover 3601, the spring acts on the clamping tooth 3604 to move away from the internal gear 3202, a torsion spring is connected between the internal gear 3202 and the clamping plate 3603, the torsion spring acts on the clamping plate 3603 to move the end of the elastic rod 3602 away from the ratchet 3301. When in use, when the winding motor 36 drives the ring cover 3601 to rotate, the one-way cooperation between the clamping plate 3603 and the ratchet 3301 can realize one-way transmission, and during one-way transmission, the end of the clamping plate 3603 is stuck between the adjacent teeth of the ratchet 3301, which can push the clamping plate 3603 to drive the elastic rod 3602 to slide on the ring cover 3601, and then drive the clamping teeth 3604 to form a cooperation with the internal gear 3202, so that the side stopper 32 can be synchronously driven to rotate. This cooperation mode can improve the stability during transmission, avoid the clamping plate 3603 from bearing the reaction force alone, and improve the service life of each component.

[0033] like Figure 9-10 As shown, the side of the mounting frame 31 is embedded with a plurality of adjustment grooves 3101, and the two sides of the adjustment grooves 3101 are symmetrically embedded with ball grooves 3102, and the adjustment grooves 3101 are slidably matched with mounting sleeves 35, and the two ends of the guide shaft 34 are respectively plugged and adapted with the corresponding mounting sleeves 35 on the mounting frame 31 on both sides. Preferably, adjacent adjustment grooves 3101 are respectively arranged horizontally and vertically, and such an arrangement can facilitate the adjustment of the height difference and horizontal spacing of adjacent guide shafts 34.

[0034] The two sides of the end of the placement sleeve 35 and the corresponding position of the ball groove 3102 are embedded with a limited sliding hole 3502, and the limiting sliding hole 3502 is elastically connected with a limiting protrusion 3503 whose end is adapted to the ball groove 3102. The end of the placement sleeve 35 is away from the adjustment groove 3101, and the opening is adapted to the end of the guide shaft 34. The outer periphery of the opening of the placement sleeve 35 is movably connected and provided with a locking knob 3506 through threaded cooperation. When in use, the end of the guide shaft 34 is inserted into the opening of the placement sleeve 35, and the guide shaft 34 can be locked by the locking knob 3506. The placement sleeve 35 can adjust the position of the placement sleeve 35 in the adjustment groove 3101 by the elastic sliding of the limiting protrusion 3503 in the limiting sliding hole 3502 and the active adaptation between the limiting protrusion 3503 and the ball groove 3102, so that the height and horizontal spacing between adjacent guide shafts 34 can be adjusted.

[0035] Furthermore, an embedding hole 3501 is embedded in the opening center of the placement sleeve 35, and the two sides of the embedding hole 3501 are connected to the limiting sliding hole 3502. The limiting protrusion 3503 is fixedly connected to a sliding rod 3504 whose end slides into the embedding hole 3501, and the end of the sliding rod 3504 extending into the embedding hole 3501 is arranged in an inclined surface. A pad 3505 is elastically connected in the opening of the placement sleeve 35, and one end of the pad 3505 slides into the embedding hole 3501. When both ends of the guide shaft 34 are assembled in the opening of the placement sleeve 35, the cushion block 3505 is elastically pressed into the opening of the placement sleeve 35, and the end thereof extending into the embedding hole 3501 can push the end of the sliding rod 3504 extending into the embedding hole 3501 out of the embedding hole 3501, and the end of the limiting protrusion 3503 extends out of the limiting sliding hole 3502, and can be matched if it is aligned with the ball groove 3102. In this way, in use, once the guide shaft 34 is assembled and fixed, the end of the cushion block 3505 extending into the embedding hole 3501 can prevent the end of the sliding rod 3504 from entering the embedding hole 3501, so that the limiting protrusion 3503 can continue to stably match with the aligned ball groove 3102, thereby maintaining the position. This method can be easily adjusted and the placement is stable. When the guide shaft 34 needs to be removed, the locking knob 3506 can be loosened to push the end of the guide shaft 34 into the placement sleeve 35 at one end, and the other end of the guide shaft 34 is separated from the placement sleeve 35, so that the removal is convenient. When the guide shaft 34 is separated from the squeezing of the cushion block 3505, the cushion block 3505 no longer blocks the sliding rod 3504 from entering the embedding hole 3501, so that the limiting protrusion 3503 is separated from the cooperation with the ball groove 3102, so that the position of the placement sleeve 35 in the adjustment groove 3101 can be adjusted.
