Upper guide rollers 113 symmetrically arranged are rotatably connected on both sides of the support frame 11 in the length direction. The film enters the entire mechanism from the tension roller 115, passes through the plurality of lower guide rollers 114, and bypasses the upper guide roller 113 far away from the tension roller 115, and bypasses the lower winding roller 112 among the winding rollers and the lower movable roller 122 among the movable rollers in sequence, and bypasses the upper guide roller 113 close to the tension roller 115, and then bypasses the upper winding roller 111 among the winding rollers and the upper movable roller 121 among the movable rollers in sequence, until the last upper winding roller 111 passes, the film is discharged and enters the next mechanism; multiple winding rollers, movable rollers and guide rollers are provided, which prolongs the path of the film in the entire mechanism, thereby increasing the storage capacity and achieving a good transition effect. When the feed end needs to be re-materialized, there is no need to stop the machine, thereby improving work efficiency.

[0032] A driving module for driving the movable frame 12 to move closer to or away from the winding roller is provided on the support seat 1. The tension sensor is electrically connected to the driving module. The tension of the film on the tension roller 115 at the feed end can be detected by the tension sensor, thereby controlling the driving module to make the movable roller move away from or closer to the winding roller, and adjusting the distance between the two, thereby adjusting the tension of the film between the winding roller and the driving roller, so that the film is flatter and more stable during transportation.

[0033] The two supporting frames 11 are provided with a linear slide rail 116 arranged in the vertical direction on the sides facing away from each other, and the two moving frames 12 are provided with two sliders 125 that slide with the linear slide rail 116 on the sides facing each other. There are two sliders 125. By setting the sliders 125 and the linear slide rail 116, the movement of the moving frame 12 is more stable. Setting two of them further improves the stability of the movement of the moving frame 12, and plays a good role of limiting support, thereby ensuring the service life of the overall structure.

[0034] The driving module includes a screw rod 311 and a driving motor 2 arranged on the top of the support seat 1 and on both sides of the support frame 11. The tension sensor is electrically connected to the driving motor 2 through a control system. The driving motor 2 adopts a variable frequency motor. The sides of the two moving frames 12 that are close to each other are fixedly connected with a driving member 124, and the driving member 124 is threadedly connected to the screw rod 311.

The transmission structure includes a corner assembly and a transmission assembly. The number of screw rods 311 is set to four, and two of them are respectively located on the sides of the two support frames 11 away from each other. The corner assembly includes a cross corner turner 3 and a T-shaped corner turner 32 and four 90-degree corner turners 31 that are symmetrically arranged with each other. The four 90-degree corner turners 31 are symmetrically arranged with twos on both sides of the cross corner turner 3 and the T-shaped corner turner 32 and are connected through a transmission rod. One end is fixedly connected to the 90-degree angler 31 through a coupling, and the other end of the screw rod 311 is fixedly connected to the side wall of the support frame 11 through a bearing seat. The cross angler 3 and the T-shaped angler 32 are connected by a connecting shaft transmission, and the two ends of the T-shaped angler 32 are connected to the 90-degree angler 31 through a transmission shaft 33. The two ends of the cross angler 3 are also connected to the 90-degree angler 31 through a transmission shaft 33. A support is fixedly connected to the side wall of the support frame 11, and a bearing seat is also provided on the support member. The screw rod 311 passes through the bearing seat and is fixedly connected to the 90-degree angler 31; by arranging the cross angler 3, the T-shaped angler 32 and the four 90-degree anglers 31, the two screw rods 311 located on the side away from each other of the two support frames 11 can move synchronously, thereby making the movement of the two moving frames 12 more stable, and the support of multiple groups of screw rods 311 also ensures the service life of the overall structure.

[0035] The transmission assembly includes a driving synchronous wheel 21 and a driven synchronous wheel 22 connected by a synchronous belt transmission. The driving synchronous wheel 21 is fixedly connected to the output shaft of the driving motor 2 through a coupling. The driven synchronous wheel 22 is transmission-connected to one end of the cross angle device 3 away from the connecting shaft. A support plate is fixedly connected to the top of the support seat 1, and a rotating seat is fixedly connected to the support plate. A brake disc 4 is rotatably connected to the rotating seat. One side of the brake disc 4 is fixedly connected to the driven synchronous wheel 22, and the other side of the brake disc 4 is fixedly connected to the cross angle device 3. The brake disc 4 is provided with a pneumatic brake 41, the pneumatic brake 41 adopts an air-compressed disc brake; by setting the pneumatic brake 41, when the movable frame 12 does not need to move, the pneumatic brake 41 can be used to brake the brake disc 4, thereby limiting the rotation of the connecting shaft and the transmission shaft 33, thereby limiting the rotation of the screw rod 311, so that the movable frame 12 is fixed in the corresponding position, so that the tension of the material at each roller on the entire mechanism is always kept stable, so that the film is flatter and more stable during transportation, and the product quality is guaranteed; the pneumatic brake 41 is also electrically connected to the control system.

[0036] An electrical box 13 is provided on the top of the support seat 1 on the side opposite to the two support frames 11, and the drive module, brake disc 4 and brake are all arranged in the electrical box 13, so as to provide good protection for the drive module, brake disc 4 and brake, thereby ensuring the service life of the overall structure.

[0037] Method of use: place the entire mechanism in the middle of the coating machine, that is, between the unloading mechanism and the coating mechanism, or between the coating mechanism and the winding mechanism, to form a transition mechanism. Preferably, it is placed between the unloading mechanism and the coating mechanism. After the film is passed from the unloading mechanism around the tension roller 115, several guide rollers, several winding rollers and several movable rollers in the entire storage mechanism, it is transported to the coating mechanism part of the coating machine. By setting multiple winding rollers, movable rollers and guide rollers, the path of the film in the entire mechanism is extended, thereby increasing the storage capacity and achieving a good transition effect. When the feed end needs to be re-fed, there is no need to stop the machine, thereby improving work efficiency.

[0038] When the machine is running, the film on the mechanism moves, and a tension sensor is set at the tension roller 115. The tension sensor can detect the tension of the film on the tension roller 115 at the feed end, and the tension sensor is electrically connected to the drive module. When the tension is small, the drive motor 2 is controlled to run, driving the synchronous wheel to rotate, thereby driving the driven synchronous wheel 22 to rotate, and driving the brake disc 4 to rotate, and through the cross angler 3, the 90-degree anglers 31 on both sides of the cross angler 3 move, driving the screw rod 311 to rotate, and the cross angler 3 away from the side of the brake disc 4 The connecting shaft rotates, driving the T-shaped angler 32 to transmit, so that the 90-degree anglers 31 on both sides of the T-shaped angler 32 move, and also driving the screw rod 311 to rotate, so that the two screw rods 311 located on the side away from each other of the two support frames 11 move synchronously, so that the movement of the two moving frames 12 is more stable, and the support of multiple groups of screw rods 311 also ensures the service life of the overall structure, controls the moving frame 12 to rise and makes the movable roller away from the winding roller, increases the distance between the movable roller and the winding roller, thereby increasing the tension at the tension roller 115 until a stable state is reached;

[0039] When the tension is large, the output shaft of the driving motor 2 is controlled to reverse, thereby controlling the four screw rods 311 to reverse, driving the moving frame 12 to descend, so that the movable roller is close to the winding roller, and the distance between the movable roller and the winding roller is reduced, thereby reducing the tension at the tension roller 115 until a stable state is reached; the tension sensor and the driving module are used to automatically adjust the film so that the film is flatter and more stable during transportation, thereby ensuring product quality;

[0040] When the tension adjustment is stable, the pneumatic brake 41 can be used to brake the brake disc 4, limiting the rotation of the connecting shaft and the transmission shaft 33, thereby limiting the rotation of the screw rod 311, so that the moving frame 12 is fixed at the corresponding position, so that the tension of the material at each roller on the entire mechanism is always kept stable, so that the film is flatter and more stable during transportation, and the product quality is guaranteed;

[0041] When no material enters the feed end of the tension roller 115, the tension sensor at the tension roller 115 does not detect the tension, and the pneumatic brake 41 releases the brake disc 4. Since the drive motor 2 adopts a variable frequency motor, the control system runs the drive motor 2 at this time, so that the output shaft of the drive motor 2 rotates slowly, and the screw rod 311 rotates slowly, so that the movable frame 12 is slowly reset. At this time, the film in the mechanism gradually loosens, increasing the length of the film in the mechanism, making it ineffective to shut down the entire coating machine, and it can also achieve the operation of replacing the coil, thereby improving work efficiency. When the material is reconnected, the tension is redetected at the tension roller 115, and the drive module is used to adjust the tension. The entire equipment does not require manual operation and is automatically adjusted to ensure work efficiency.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be regarded as within the scope of protection of the present invention.
