Detailed implementation manner

[0029] Please refer to Figures 1-4 , in the embodiment of the present invention, a film conveying device includes symmetrically arranged supports 1. A horizontally arranged mounting frame 2 is slidably connected to the opposite sides of the two supports 1. The horizontally arranged mounting frame 2 can be vertically slidably arranged on the support 1. A lifting motor 21 for driving the vertically moving of the horizontally arranged mounting frame 2 on the support 1 is provided on one side of the support 1. Preferably, sprockets are distributed vertically in the support 1, and a chain is drivingly connected to the periphery of the sprockets. The horizontally arranged mounting frame 2 is installed on the chain. In this way, when the lifting motor 21 drives the sprockets and the chain to rotate, the horizontally arranged mounting frame 2 can be driven to move vertically. Similarly, the transmission can also be achieved by using a lead screw slider. A plurality of groups of parallel arranged conveying rollers 22 are rotatably connected to the horizontally arranged mounting frame 2. The conveying rollers 22 are synchronously drivingly connected by a chain or a belt. A conveying motor 23 for driving the rotation of the conveying rollers 22 is drivingly connected to one side of the conveying rollers 22. The conveying rollers 22 on both sides can be synchronously drivingly connected by a shaft. A bottom plate 3 is provided on the conveying rollers 22. Guide grooves sleeved on the outer edges of the bottom plate 3 are symmetrically and fixedly connected to both sides of the horizontally arranged mounting frame 2. After starting the conveying motor 23, the bottom plate 3 can be driven to move along the guide grooves by the conveying rollers 22. A mounting mechanism for mounting the film is installed on the bottom plate 3. Starting the lifting motor 21 can drive the horizontally arranged mounting frame 2, thereby driving the mounting mechanism on the bottom plate 3 to adjust the mounting height. Starting the conveying motor 23 can drive the rotation of the conveying rollers 22, thereby driving the bottom plate 3 to move along the guide grooves by the conveying rollers 22. The mounting mechanism includes symmetrically arranged mounting frame plates 31 on the bottom plate 3. A side blocking rotating plate 32 is rotatably connected to the mounting frame plates 31. A winding shaft 33 is fixedly connected between the side blocking rotating plates 32 on both sides. One end of the winding shaft 33 is drivingly connected to a one-way transmission assembly.

[0030] During use, adjust the height of the bottom plate 3 and its distance relative to the working process as needed. Starting the one-way drive assembly can drive the winding shaft 33 to rotate to achieve winding of the film. 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 drive assembly disengages from the traction of the winding shaft 33, which will not affect the release of the film. The overall installation is stable and convenient, and it is convenient to wind and release the film.

[0031] Among them, as Figure 4 shown, a plurality of guide shafts 34 with different heights are also connected and arranged between the mounting frame plates 31. The film is wound around the periphery of the winding shaft 33, and its free end sequentially bypasses the periphery of the guide shafts 34. The film can be tightened through adjacent guide shafts 34 to keep the surface of the film flat for transportation. At the same time, the arrangement of the guide shafts 34 with different heights can also prevent the end of the film from falling. Preferably, the position of the guide shaft 34 can be set to be adjustable, so as to facilitate adjustment according to needs.

[0032] As Figures 5-8 shown, a ratchet wheel 3301 is fixedly connected to the outer periphery of the end of the winding shaft 33. A winding motor 36 is installed on the outer side of the mounting frame plate 31. The output end of the winding motor 36 is fixedly connected with a one-way drive assembly that is in one-way drive connection with the ratchet wheel 3301. A through hole 3201 for the winding shaft 33 to pass through is provided in the middle of the side baffle plate 32. An internal gear 3202 is provided on the edge of the side baffle plate 32 facing the winding motor 36. The one-way drive assembly and the internal gear 3202 are correspondingly adapted. During use, when the winding motor 36 drives the one-way drive assembly to rotate to cooperate with the ratchet wheel 3301 to drive the winding shaft 33 to rotate and wind the film, it can also be synchronized with the internal gear 3202 to drive the side baffle plate 32 to rotate synchronously, so as to improve the stability during winding. When there is a large amount and heavy weight of the film, the winding resistance will not affect the driving effect of the winding motor 36.

[0033] Among them, the one-way transmission assembly includes a ring cover 3601 fixedly connected to the output end of the winding motor 36. The ring cover 3601 is concentrically sleeved around the periphery of the ratchet wheel 3301 towards one side of the side baffle rotating plate 32. A plurality of elastic rods 3602 are slidably penetrated through the edge of the ring cover 3601. A tooth 3604 corresponding to and meshing with the internal gear 3202 is fixedly connected to the end of the elastic rod 3602 facing the internal gear 3202. A clamping plate 3603 corresponding to and clamping with the ratchet wheel 3301 is rotatably connected to one side of the internal gear 3202 facing the ratchet wheel 3301. Preferably, four elastic rods 3602 are arranged in a cross-shaped array with the center of the winding shaft 33 as the origin. A spring is connected between the elastic rod 3602 and the ring cover 3601. The spring acts on the tooth 3604 to keep it 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 keep the end away from the elastic rod 3602 close to the ratchet wheel 3301. During 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 wheel 3301 can achieve one-way transmission. And during one-way transmission, the end of the clamping plate 3603 is stuck between adjacent teeth of the ratchet wheel 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 tooth 3604 to form a cooperation with the internal gear 3202, so as to synchronously drive the side baffle rotating plate 32 to rotate. This cooperation method can improve the stability during transmission, avoid the clamping plate 3603 solely bearing the reaction force, and can improve the service life of each component.

[0034] As Figures 9-10 shown, a plurality of adjustment grooves 3101 are embedded on the side of the placement frame plate 31. Ball grooves 3102 are symmetrically embedded on both sides in the adjustment grooves 3101. A placement socket 35 is slidably fitted in the adjustment grooves 3101. The two ends of the guide shaft 34 are respectively inserted and fitted with the corresponding placement sockets 35 on the two side placement frame plates 31. Preferably, adjacent adjustment grooves 3101 are respectively horizontally arranged and vertically arranged. Such an arrangement can facilitate the adjustment of the height difference and horizontal distance between adjacent guide shafts 34.

[0035] On both sides of the end of the mounting socket 35 corresponding to the ball groove 3102, limiting sliding holes 3502 are embedded. An elastic connection is provided in the limiting sliding holes 3502 with limiting protrusions 3503 whose ends are correspondingly adapted to the ball groove 3102. The end of the mounting socket 35 away from the adjustment groove 3101 is open, and the opening is correspondingly adapted to the end of the guiding shaft 34. A locking knob 3506 is movably penetrated through the periphery of the opening of the mounting socket 35 by means of thread fitting. When in use, the end of the guiding shaft 34 is inserted into the opening of the mounting socket 35, and the guiding shaft 34 can be locked by the locking knob 3506. The mounting socket 35 can adjust the position of the mounting socket 35 in the adjustment groove 3101 by utilizing the elastic sliding of the limiting protrusions 3503 in the limiting sliding holes 3502 and the movable adaptation between the limiting protrusions 3503 and the ball groove 3102, so that the height and horizontal distance between adjacent guiding shafts 34 can be adjusted.

[0036] Furthermore, an embedding hole 3501 is embedded at the center of the opening of the mounting socket 35. Both sides of the embedding hole 3501 are communicated with the limiting sliding holes 3502. The limiting protrusion 3503 is fixedly connected with a sliding rod 3504 whose end slides into the embedding hole 3501. The end of the sliding rod 3504 extending into the embedding hole 3501 is arranged in an inclined plane. An elastic connection is provided in the opening of the mounting socket 35 with a cushion block 3505. One end of the cushion block 3505 slides into the embedding hole 3501. When both ends of the guiding shaft 34 are assembled in the opening of the mounting socket 35, the cushion block 3505 is elastically pressed into the opening of the mounting socket 35, and one end of it 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. If it is aligned with the ball groove 3102, the cooperation can be realized. In this way, during use, once the guiding shaft 34 is assembled and fixed, one 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 continuously and stably cooperate with the aligned ball groove 3102, thereby maintaining the position. This method is convenient for adjustment and has a stable installation. When it is necessary to remove the guiding shaft 34, the locking knob 3506 can be loosened, and the end of the guiding shaft 34 is pushed into the mounting socket 35 at one end, and the other end will be separated from the mounting socket 35, thus facilitating disassembly. When the guiding shaft 34 is disengaged from the extrusion 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 disengaged from the cooperation with the ball groove 3102, and thus the position of the mounting socket 35 in the adjustment groove 3101 can be adjusted.
