Description

Technical Field

[0001] This invention relates to the field of film winding device technology, and more specifically to an adjustable film winding device. Background Technology

[0002] When packaging glass, packaging film is often required. Packaging film is usually stored in rolls. Before use, the size of the packaging film is determined according to the size of the glass. Then the packaging film is cut. After the packaging film is cut to the appropriate size, it is stored for subsequent packaging work.

[0003] In practical use, large factories typically employ automated cutting. After adjusting the parameters, the packaging film can be cut using a cutting machine. For small factories, cutting machines are more expensive, so manual cutting is usually used. First, the packaging film is unwound and wound onto a film winding frame. Then, the film winding frame is cut to obtain the cut packaging film. The size of the packaging film is determined by the spacing of the support rods in the film winding frame; that is, the larger the spacing of the support rods, the wider the packaging film.

[0004] However, in actual use, the film wrapping frame is usually a fixed structure, which can only be cut for a single size, making it difficult to meet the cutting needs of different sizes of packaging film.

[0005] Therefore, an adjustable film winding device is needed to overcome the above problems. Summary of the Invention

[0006] To address the aforementioned problems, the present invention provides an adjustable film winding device, thereby achieving the objective of resolving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention specifically adopts the following technical solution: an adjustable film winding device, comprising a fixed frame, on which a film winding frame is rotatably mounted, and a driving structure for driving the film winding frame to rotate; the film winding frame includes two housings rotatably mounted on the fixed frame, a lead screw rotatably mounted inside each housing, a worm gear fixedly connected to one end of the lead screw, a worm rotatably mounted inside the housing and meshing with the worm gear, a first gear fixedly connected to one end of the worm, a second gear rotatably mounted inside the housing and meshing with the first gear, a limiting rod fixedly connected inside the housing, and a support rod threadedly connected to the outside of the lead screw; the support rod is located between the two housings, one end of the support rod is threadedly connected to the outside of the lead screw mounted on one of the housings, and the other end of the support rod is sleeved on the outside of the limiting rod mounted on the other housing.

[0008] As a further improvement to the above technical solution:

[0009] The interior of the housing is provided with three lead screws and three limit rods arranged at equal intervals, with the position of one lead screw on the housing corresponding to the position of the limit rod on the other housing.

[0010] A linkage structure is provided between the two shells;

[0011] The linkage structure includes a connecting rod one fixedly connected to one side of gear two inside one of the housings, a connecting rod two fixedly connected to one side of gear two inside the other housing, a connecting block fixedly connected to one end of connecting rod one, and a linkage rod sleeved on connecting rod two and capable of being snapped into the connecting block.

[0012] One end of one of the support rods is rotatably connected to a measuring ruler, and one end of the two support rods on the adjacent side of the support rod is provided with a limit structure.

[0013] The limiting structure includes a base block fixedly connected to one end of the support rod and a limiting block elastically slidably disposed inside the base block by a spring.

[0014] The limiting block is rotatably positioned inside the base block.

[0015] Both ends of the support rod are fixedly connected to clamps by bolts.

[0016] Both the support rod and the clamp plate are provided with cutting grooves.

[0028] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0029] See Figures 1 to 7 The present invention discloses an adjustable film winding device, including a fixed frame 1, a film winding frame 2 rotatably mounted on the fixed frame 1, and a driving structure 4 for driving the film winding frame 2 to rotate on the fixed frame 1.

[0030] The film wrapping frame 2 includes two housings 21 rotatably mounted on the fixed frame 1. Inside each housing 21, a lead screw 22 is rotatably mounted. A worm gear 23 is fixedly connected to one end of the lead screw 22. A worm 24 is rotatably mounted inside the housing 21 and meshes with the worm gear 23. A gear 25 is fixedly connected to one end of the worm 24. A gear 26 is rotatably mounted inside the housing 21 and meshes with the gear 25. A limiting rod 27 is fixedly connected inside the housing 21. A support rod 28 is threadedly connected to the outside of the lead screw 22. The limiting rod 27 is a square rod.

[0031] The support rod 28 is located between the two housings 21. One end of the support rod 28 is threaded to the outside of the lead screw 22 provided on one of the housings 21, and the other end of the support rod 28 is sleeved on the outside of the limiting rod 27 provided on the other housing 21.

[0032] In actual use, the drive structure 4 drives the film winding frame 2 to rotate, thereby winding the packaging film onto the film winding frame 2;

[0033] In actual use, after rotating gear 26, gear 25 rotates, which in turn causes worm 24 to rotate, which in turn drives worm wheel 23 and lead screw 22 to rotate. After the lead screw 22 rotates, the support rod 28 moves along the lead screw 22, thereby adjusting the distance between the support rods 28 to meet the cutting requirements of different sizes.

[0034] As a further explanation of this application:

[0035] The interior of housing 21 is provided with three lead screws 22 and three limit rods 27 at equal intervals and staggered. The position of the lead screw 22 on one housing 21 corresponds to the position of the limit rod 27 on the other housing 21.

[0036] In actual use, each housing 21 can adjust three support rods 28, and two housings 21 can adjust six support rods 28.

[0037] As a further explanation of this application:

[0038] A linkage structure 3 is provided between the two shells 21;

[0039] The linkage structure 3 includes a connecting rod 31 fixedly connected to one side of the gear 26 inside one of the housings 21, a connecting rod 32 fixedly connected to one side of the gear 26 inside the other housing 21, a connecting block 33 fixedly connected to one end of the connecting rod 31, and a linkage rod 34 sleeved on the connecting rod 32 and capable of being engaged inside the connecting block 33; both the connecting rod 32 and the linkage rod 34 are square rods, so that when the connecting block 33 is rotated, the gear 26 can be rotated through the linkage rod 34 and the connecting rod 32.

[0040] When simultaneous adjustment is required, the linkage rod 34 is inserted into the interior of the connecting block 33, and then the connecting block 33 is rotated with a wrench, thereby driving the connecting rod 31 and the linkage rod 34 to rotate, thereby driving the gear 26 inside the two housings 21 to rotate simultaneously, so that the six support rods 28 can move to achieve the purpose of adjusting the spacing between the support rods 28.

[0041] When separate adjustment is required, the linkage rod 34 is separated from the connecting block 33. When the connecting block 33 is turned with a wrench, the gear 26, which is fixedly connected to the connecting rod 31, rotates, thereby causing the three support rods 28 to move.

[0042] In actual use, the six support rods 28 form a hexagonal structure. The side length of the hexagon is equal to the distance between the support rods 28, which determines the width of the cut packaging film. When adjusted separately, the three support rods 28 form a triangular structure. The side length of the triangle is equal to the distance between the support rods 28, which determines the width of the cut packaging film. When the length of the lead screw 22 is the same, the maximum side length of the triangle is greater than the maximum side length of the hexagon, thereby increasing the cut width of the packaging film.

[0043] In actual use, the linkage rod 34 is inserted into the connecting block 33, and the connecting block 33 is rotated so that all six support rods 28 move to the root position of the lead screw 22. Then the linkage rod 34 is separated from the connecting block 33. Then the connecting block 33 is rotated. At this time, three support rods 28 move, while the other three support rods 28 do not move. That is, the packaging film is wound on the film winding frame 2 by three support rods 28, thereby increasing the cut width of the packaging film.

[0044] That is, through the linkage structure 3, it is possible to adjust all six support rods 28 at the same time, or to adjust only three support rods 28 at the same time, so as to meet the usage needs in different scenarios.

[0045] As a further explanation of this application:

[0046] One end of one of the support rods 28 is rotatably connected to a measuring ruler 13, and one end of the two support rods 28 on the adjacent side of the support rod 28 is provided with a limit structure 5;

[0047] In practical use, the spacing between the support rods 28 can be measured using the measuring ruler 13, thereby adjusting the spacing between the support rods 28 according to the required packaging film size. In practical use, since one end of the two support rods 28 on the adjacent side is provided with a limiting structure 5, when adjusting the three support rods 28 at the same time, the measuring ruler 13 is set in the limiting structure 5 on another support rod 28. That is, by setting the measuring ruler 13, the spacing between the support rods 28 in the hexagonal structure can be measured, and the spacing between the support rods 28 in the triangular structure can also be measured.

[0048] As a further explanation of this application:

[0049] The limiting structure 5 includes a base block 51 fixedly connected to one end of the support rod 28 and a limiting block 52 elastically slidably disposed inside the base block 51 by a spring 53; the limiting block 52 is rotatably disposed inside the base block 51; in actual use, the limiting block 52 is snapped onto the outside of the measuring ruler 13, so that when the membrane frame 2 rotates, the measuring ruler 13 can be prevented from rotating on its own.

[0050] As a further explanation of this application:

[0051] Both ends of the support rod 28 are fixedly connected to the clamping plate 7 by bolts 6. When wrapping the film, the end of the packaging film is first clamped and fixed to one of the support rods 28 by the clamping plate 7, and then the winding begins. After the winding is completed, the clamping plate 7 clamps the wound packaging film to fix the packaging film and prevent it from unraveling when the packaging film is cut.

[0052] As a further explanation of this application:

[0053] Both the support rod 28 and the clamping plate 7 are provided with cutting grooves 8, and the packaging film is cut by using a cutting tool through the cutting grooves 8.

[0054] As a further explanation of this application:

[0055] The drive structure 4 includes a sprocket 9 fixedly connected to one of the housings 21, a sprocket 10 rotatably connected to the fixed frame 1, and a motor 11 disposed on one side of the sprocket 10 for driving the sprocket 10 to rotate; the sprocket 9 and the sprocket 10 are connected by a chain 12.

[0056] In actual use, motor 11 drives sprocket 2 10 to rotate, which in turn drives sprocket 1 9 to rotate via chain 12, which in turn drives one of the housings 21 to rotate, that is, drives the film winding frame 2 to rotate.
