[0003] Traditional methods of bending Mylar sheets typically require a lot of manual intervention, have low automation, high labor costs, and are not very efficient. Utility Model Content

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] A bending aid for melatonin sheets, such as Figures 1-3 As shown, the device includes a main body 1, which includes a frame 2, a bending assembly 3, a lifting assembly 4, and a rotating assembly 5. The components work together to bend and collect Mylar sheets. The frame 2 includes a top plate 21 and four support rods 22 set at the corners of the top plate 21. The bottom of the support rods 22 is fixedly connected to a base plate 23. The frame 2 mainly serves as the main load-bearing structure of the main body 1. All components are fixedly connected to the frame 2. The frame 2 is made of high-strength metal, which makes the main body 1 more stable.

[0018] like Figures 1-3 As shown, the bending assembly 3 includes a cylinder 31 and a pressure head 32. The cylinder 31 is fixedly connected above the top plate 21. The top plate 21 has a through hole. The piston rod of the cylinder 31 passes through the through hole and is fixedly connected to the pressure head 32. The pressure head 32 is mainly used to bend Mylar sheets. A fixing frame 33 is fixedly connected to the outer shaft wall of the pressure head 32. Four lifting assemblies 4 are fixedly connected to the corners of the fixing frame 33. The fixing frame 33 is mainly used to connect the pressure head 32 and the lifting assemblies 4 together, so that the lifting assemblies 4 can be raised and lowered by the cylinder 31 controlling the pressure head 32.

[0019] like Figures 1-3As shown, the lifting assembly 4 is mainly used to connect the bending assembly 3 and the rotating assembly 5, and is the most important structure. The lifting assembly 4 includes a first lifting rod 41, a second lifting rod 42, and a third lifting rod 43. The first lifting rod 41 and the second lifting rod 42 are arranged horizontally and symmetrically. The third lifting rod 43 has a first sliding groove 431 and a second sliding groove 432. The top of the first lifting rod 41 is fixedly connected to the fixed frame 33, and the bottom of the second lifting rod 42 is fixedly connected to the base plate 23. The bottom of the first lifting rod 41 is provided with a first flange 411. The top of the second lifting rod 42 is provided with a second flange 421. Due to the first flange 411 and the second flange 421, the first lifting rod 41 and the second lifting rod 42 will not detach from the third lifting rod 43, thus preventing the lifting assembly 4 from falling apart. The first flange 411 is slidably connected to the first slide groove 431, and the second flange 421 is slidably connected to the second slide groove 432. The first slide groove 431 is provided with a first row of raised patterns 434 and a second row of raised patterns 435. The first row of raised patterns 434 and the second row of raised patterns 435 are respectively provided in the first slide groove 431. At the top and bottom of 1, when the pressure head 32 is at its highest point, the first flange 411 is above the first row of ridges 434, and both ends of the lifting assembly 4 are stretched to their maximum length. When the pressure head 32 presses down, because the bottom of the first flange 411 is obstructed by the first row of ridges 434, the pressure head 32 drives the first lifting rod 41 to push the third lifting rod 43 down, and the second lifting rod 42 inserts into the innermost part of the second slide groove 432. At this time, the pressure head 32 is about to begin bending the Mylar film, and then the first flange 411 breaks through the first row of ridges 434 and the second row of ridges 434. Obstructed by the ridge 435, the pressure head 32 reaches below the second ridge 435. At this moment, the pressure head 32 has bent and shaped the Mylar film. When the pressure head 32 rises, because the top of the first flange 411 is obstructed by the second ridge 435, the pressure head 32 drives the first lifting rod 41 to pull the third lifting rod 43 upward until the second flange 421 reaches the bottom of the second groove 432. The first flange 411 breaks through the obstruction of the second ridge 435 and the first ridge 434 and reaches above the first ridge 434. At this moment, the pressure head 32 returns to its original position.

[0020] like Figures 1-3As shown, a chain 433 is attached to the side of the third lifting rod 43 facing the rotating assembly 5. Two rotating assemblies 5 are provided, arranged opposite each other. Each rotating assembly 5 includes a rotating plate 51, two gears 52, and two fixed rods 53. A rotating roller passes through one end of the rotating plate 51, and both ends of the rotating roller are connected to the shafts of the fixed rods 53. Each gear 52 is fixedly connected to the rotating roller between the rotating plate 51 and the fixed rods 53. Each gear 52 corresponds to one lifting assembly 4, and the gear 52 meshes with the chain 433. Therefore, the gear 52 can move with the third lifting assembly 43. The rod 43 rises and rotates, causing the rotating plate 51 to rotate. The bottom of the fixed rod 53 is fixedly connected to the base plate 23. When the pressure head 32 is at its highest position, the gear 52 is engaged at the bottom of the chain 433. At this time, the ends of the two opposing rotating plates 51 furthest from the gear 52 are at their farthest point, meaning the rotating assembly 5 is in the open state. The bent Mylar sheet falls into the material box 6 below the rotating assembly 5. When the pressure head 32 is at its lowest position, the gear 52 is engaged at the bottom of the chain 433. At this time, the ends of the two opposing rotating plates 51 furthest from the gear 52 are at their closest point. Whenever the pressure head 32 rises or falls, due to the special design of the lifting assembly 4, the third lifting rod 43 rises or falls first. That is, when the pressure head 32 reaches the point where it is about to bend the Mylar sheet from its highest point, the third lifting rod 43 is first driven down by the first lifting rod 41, and the two rotating assemblies 5 are driven to come together. When bending the Mylar sheet subsequently, because the second flange 421 on the second lifting rod 42 reaches the highest point of the second slide groove 432, the third lifting rod 43 cannot fall. At this time, the gear 52 is engaged at the top of the chain 433, and the third lifting rod 43... The height of component 3 remains unchanged, meaning the two rotating components 5 do not change, and the bending operation proceeds normally. When the pressure head 32 rises from the lowest point, the third lifting rod 43 is first driven to rise by the first lifting rod 41, and the two rotating components 5 are driven to open outward. The formed Mylar sheet falls into the material box 6. Until the gear 52 meshes with the lowest point of the chain 433, the second flange 421 of the second lifting rod 42 reaches the lowest point of the second slide 432. At this moment, the two rotating components 5 are opened to the maximum extent, and the subsequent rise of the pressure head 32 to the highest point will not affect the rotating components 5.

All technical solutions falling within the scope of this utility model's concept are protected.
