[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figure 1-6 , a feeding device for a UV molding machine, comprising a connecting frame 1, on which a feeding mechanism is provided;

[0025] The feeding mechanism includes a placement rack 2 fixedly connected to the connecting rack 1, and a driving assembly for driving the coil to rotate is provided on one side of the placement rack 2, wherein the placement rack 2 is provided with two positions for placing the coil, and two driving assemblies are provided. When the coil is placed on the placement rack 2, the coil can rotate freely, and the connecting rack 1 is also rotatably connected to a plurality of pinch rollers 3, and an auxiliary roller 4 is provided between the pinch rollers 3 and the placement rack 2, and the connecting rack 1 is also provided with an electric push rod 5, and the output end of the electric push rod 5 is fixedly connected to the support frame 6, and a hot pressing roller 7 is provided on the connecting rack 1, and a detection rod 8 is rotatably connected to the placement rack 2 through a spring shaft, and a detection wheel 9 is rotatably connected to the detection rod 8, and a displacement sensor is provided on the side wall of the placement rack 2 near the detection wheel 9, and the displacement sensor is electrically connected to the controller;

[0026] In this design, two rolls can be placed on the placement rack 2 to feed the UV molding machine, and the end of the roll to be used is fixed on the auxiliary roller 4 or the hot pressing roller 7. During the operation of the UV film press, the driving component drives one of the rolls to rotate for unloading operation, and then the film material passes through the position between the auxiliary roller 4 and the hot pressing roller 7 and moves to the pinch roller 3, and enters the UV molding machine under the drive of the pinch roller 3. At the same time, the detection wheel 9 remains in a state of contact with the roll, and as the unloading operation proceeds, the outer diameter of the roll becomes smaller. When the detection wheel 9 moves to the moving range After the temperature reaches 0, the controller controls the electric push rod 5 to operate, so that the hot pressing roller 7 moves toward the auxiliary roller 4, driving the roll to be used to abut against the end of the roll being conveyed and perform hot pressing to combine the tail of the upper roll of film material with the end of the next roll of film material. There is no need for the UV film pressing equipment to stop and wait, and the user can place a new roll of film material on the placement rack 2 within the time period before the replaced roll of film material is used up. The requirement for the timing of manual material replacement is low. This design achieves the purpose of continuous feeding, can reduce downtime, improve production efficiency, and does not require manual supervision of roll replacement time.

[0027] It should be noted that there is often a certain amount of waste material in the overlapping parts of the coil and the ends and tails of the coil that cannot be used directly. The film pressing equipment is designed with a corresponding cutting mechanism, and there is no need to repeat it in the loading device. Secondly, when the electric push rod 5 is running, the drive component should also change the speed appropriately to avoid the film material being stretched and causing deformation and breakage.

[0028] Furthermore, the drive assembly includes a drive motor 10, the output end of the drive motor 10 is fixedly connected to a connecting rod 12, an inner support sleeve 13 is slidably connected to the connecting rod 12, and a conical block 11 is provided at one end of the connecting rod 12 away from the drive motor 10, and the conical block 11 is arranged to abut against the inner support sleeve 13;

[0029] In this design, the conical block 11 is in the shape of a cone. After the user places the coil in the placement rack 2, he can slide the inner support sleeve 13 in the direction of the coil and insert the inner support sleeve 13 into the core of the coil. At this time, the conical block 11 drives the inner support block to deform, so that the outer diameter of the inner support block becomes larger and is against the inner wall of the core. The friction force can be used to keep the inner support block in this state. At the same time, when the drive motor 10 rotates, it can cooperate with the inner support block to drive the coil to rotate, thereby achieving the purpose of driving the coil to discharge.

[0030] Furthermore, the inner support sleeve 13 is embedded with a plurality of rollers 15, the rollers 15 are made of rubber, and the inner support sleeve 13 is provided with a plurality of expansion slots 14, the conical block 11 is provided with a clearance slot 16, and the rollers 15 are arranged to abut against the inner wall of the clearance slot 16;

[0031] In this design, the roller 15 is provided to facilitate the insertion of the inner support sleeve 13 into the barrel core or the extraction of the inner support sleeve from the barrel core. At the same time, the clearance groove 16 is provided to clamp the main roller 15, so that during the operation of the drive assembly, the inner support sleeve 13 will not be separated from the barrel core, and manual operation is required for separation, thereby ensuring the stability of the discharge operation.

[0032] Furthermore, one end of the placement rack 2 away from the driving assembly is fixedly connected to a stabilizing rack 17, and a limiting rod 18 is slidably connected to the stabilizing rack 17;

[0033] In this design, a limiting rod 18 is provided to stabilize one end of the coil away from the drive assembly, ensuring stable rotation of the coil during unwinding operation.

[0034] Furthermore, the hot pressing roller 7 and the auxiliary roller 4 are both provided with transverse grooves, in which clamping strips 19 are clamped. The clamping strips 19 include connecting plates, and the lower surfaces of both ends of the connecting plates are fixedly connected with elastic clips matching the transverse grooves.

[0035] Based on the above design, a method is provided to temporarily fix the end of the film material on the hot pressing roller 7 or the auxiliary roller 4. The clamp 19 is removed, and then the end of the film material is placed on the transverse groove, and then the clamp 19 is put back into the transverse groove to fix the film material. As the pinch roller 3 continues to run, the film material will become thinner after being stretched, and then it will be separated from the transverse groove and the clamp 19.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
