[0038] As Figures 1-7 shown, the present utility model provides an adjustable foil winding mechanism. The adjustable foil winding mechanism includes support vertical plates 1 arranged vertically on both sides. A guide roller 2 arranged horizontally is installed at the upper end of the support vertical plate 1. It further includes: an adjusting mechanism 5, the upper end of which is installed on one end of the guide roller 2, and includes a fixed plate 51 and a second rocker arm 52 that can move and adjust relative to each other; a first avoidance cavity 56 is formed on the side surface of the fixed plate 51 close to the second rocker arm 52. An adjusting block 53 is fixedly provided on the side surface of the second rocker arm 52 close to the fixed plate 51. A first threaded through hole 531 is formed on the top end surface of the adjusting block 53. The adjusting block 53 is arranged in the first avoidance cavity 56, and the first avoidance cavity 56 is larger than the adjusting block 53; a circular through hole corresponding to the first threaded through hole 531 and a second threaded through hole 551 are arranged at intervals at the top of the first avoidance cavity 56; an upper adjusting screw 54 passes through the circular through hole and is threadedly connected to the first threaded through hole 531 for upward adjustment of the second rocker arm 52; a lower adjusting screw 55 passes through the second threaded through hole 551 and abuts against the top end of the adjusting block 53 for downward adjustment of the second rocker arm 52; a first rocker arm 4, the upper end of which is installed on the other end of the guide roller 2 away from the adjusting mechanism 5, and a winding roller 3 for winding the foil is further connected between the lower end of the first rocker arm 4 and the lower end of the second rocker arm 52; wherein, air cylinders 7 are respectively connected to the bottom surfaces of the lower ends of the first rocker arm 4 and the fixed plate 51.
[0039] An adjustable foil winding mechanism provided by the utility model, by arranging a first avoidance cavity 56 on the side surface of a fixed plate 51, a regulating block 53 is fixedly arranged on one side surface of a second swing arm 52 close to the fixed plate 51. A first threaded through hole 531 is arranged on the top surface of the regulating block 53. The regulating block 53 is arranged in the first avoidance cavity 56. A circular through hole corresponding to the first threaded through hole 531 and a second threaded through hole 551 are arranged at intervals on the top of the first avoidance cavity 56. An upper regulating screw 54 and a lower regulating screw 55 are respectively arranged in the circular through hole and the second threaded hole. When it is necessary to calibrate the levelness of a winding roller 3, rotate the upper regulating screw 54 until the top end of the upper regulating screw 54 abuts against the bottom of the first avoidance cavity 56. At this time, continuing to rotate the upper regulating screw 54 can make the first swing arm 4 move upward, and at the same time drive the winding roller 3 to adjust its levelness upward. When rotating the lower regulating screw 55, the top end of the lower regulating screw 55 abuts against the top surface of the regulating block 53. At this time, continuing to rotate the lower regulating screw 55 can make the first swing arm 4 move downward, and at the same time drive the winding roller 3 to adjust its levelness downward. Under the above structure, the adjustable foil winding mechanism of the utility model can accurately adjust the levelness of the winding roller 3, ensure the tightness of the coil during the winding work of the foil, reduce the phenomena of looseness and folding, and ensure the quality and stability of the coil.
[0040] In this embodiment, as Figures 1-2 shown, a guiding roller 2 is horizontally installed at the upper end position between two side supporting vertical plates 1. Bearings are respectively arranged at both ends of the guiding roller 2 and are rotatably fixed on the supporting vertical plates 1. A first swing arm 4 and a regulating mechanism 5 are respectively installed at the guiding shaft end parts close to the inner sides of the two side supporting vertical plates 1. A shaft hole 58 is arranged at the upper end positions of the first swing arm 4 and the regulating mechanism 5. Key grooves 581 are arranged in the shaft holes 58 of the first swing arm 4, the fixed plate 51 and the guiding roller 2 installed in the shaft holes 58 thereof. The first swing arm 4 and the fixed plate 51 are fixedly connected with the guiding roller 2 by arranging key pins in the key grooves 581, that is to say, the first swing arm 4 and the fixed plate 51 can rotate synchronously with the guiding roller 2. A cylinder 7 is respectively connected to the bottom surfaces of the lower ends of the first swing arm 4 and the fixed plate 51. The bottom of the cylinder 7 is fixedly installed on the two side supporting vertical plates 1 through a base. The telescopic movement of the cylinder 7 can drive the first swing arm 4 and the regulating mechanism 5 to swing up and down, so as to drive the winding roller 3 to swing up and down. When one of the cylinders 7 is driven alone, the levelness of the winding roller 3 can be adjusted greatly. In order to adjust the levelness of the winding roller 3 more accurately, a second swing arm 52 is arranged on one side of the fixed plate 51. A bearing is arranged in the shaft hole 58 at the upper end of the second swing arm 52. The guiding roller 2 passes through the bearing and is rotatably connected with the second swing arm 52.
[0041] Specifically, as Figures 3 to 7As shown in the figure, a first avoidance cavity 56 is formed on the side of the fixed plate 51 close to the second swing arm 52. An adjusting block 53 is fixedly arranged on one side of the second swing arm 52 close to the fixed plate 51. A first threaded through hole 531 is formed on the top end surface of the adjusting block 53. The adjusting block 53 is arranged in the first avoidance cavity 56, and the first avoidance cavity 56 is larger than the adjusting block 53. A circular through hole corresponding to the first threaded through hole 531 and a second threaded through hole 551 are arranged at intervals on the top of the first avoidance cavity 56. An upper adjusting screw rod 54 is arranged in the circular through hole. The upper adjusting screw rod 54 passes through the circular through hole and is threadedly connected with the first threaded through hole 531. When it is necessary to upwardly adjust the winding roller 3 close to one end of the adjusting mechanism 5, the upper adjusting screw rod 54 is rotated clockwise until the top of the upper adjusting screw rod 54 abuts against the bottom of the first avoidance cavity 56. When the upper adjusting screw rod 54 is continuously rotated clockwise, the adjusting block 53 will move upward following the rotation of the upper adjusting screw rod 54. At this time, the second swing arm 52 will move upward together with the adjusting block 53, so as to upwardly move the winding roller 3 close to one end of the adjusting mechanism 5. Since the threaded rotation movement between the screw rod and the first threaded through hole 531 on the adjusting block 53 can achieve precise adjustment.
[0042] Further, a lower adjusting screw rod 55 is arranged in the second threaded through hole 551. When it is necessary to downwardly adjust the winding roller 3 close to one end of the adjusting mechanism 5, the lower adjusting screw rod 55 is rotated clockwise until the top of the lower adjusting screw rod 55 abuts against the top of the adjusting block 53. When the lower adjusting screw rod 55 is continuously rotated clockwise, the adjusting block 53 will move downward under the downward pressure of the lower adjusting screw rod 55. At this time, the second swing arm 52 will move downward together with the adjusting block 53, so as to downwardly move the winding roller 3 close to one end of the adjusting mechanism 5. Similarly, since the threaded rotation movement between the screw rod and the second threaded through hole 551 on the fixed plate 51 can achieve precise adjustment, the winding roller 3 can be brought to a relatively horizontal state, ensuring the tightness of the coil during the winding work of the foil material, reducing the phenomena of looseness and folding, and ensuring the quality and stability of the coil.
[0043] In this embodiment, as Figure 6As shown, when the winding roller 3 is adjusted upward, the weight of the winding roller 3 itself makes it rather laborious to rotate the upper adjusting screw 54. To solve this problem, a nut 541 is fixed at the upper end of the circular through-hole, and the nut 541 is coaxial with the circular through-hole. The upper adjusting screw 54 passes through the nut 541, the circular through-hole, and the first threaded through-hole 531 in sequence and finally abuts against the bottom of the first avoidance cavity 56. The setting of the nut 541 not only ensures the stability when rotating the upper adjusting screw 54, but also makes it more labor-saving during rotation, further ensuring the adjustment accuracy of the winding roller 3. At the same time, both the upper adjusting screw 54 and the lower adjusting screw 55 adopt screws with hexagonal nuts 541, and the winding roller 3 can be easily adjusted by manually rotating the hexagonal nut 541.
[0044] In this embodiment, as Figure 2 and Figure 3 shown, bearing collars 6 are provided at the lower ends of the first swing arm 4 and the second swing arm 52. The bearing collars 6 adopt a quick-release structure. The bearings at both ends of the winding roller 3 are installed in the bearing collars 6. When the winding roller 3 needs to be taken or placed, only need to loosen the quick-release screw on the bearing collar 6 and open the bearing collar 6 to take or place the winding roller 3, which improves the work efficiency.
[0045] Specifically, as Figure 4 and Figure 6 shown, a plurality of counterbores are provided at intervals on the side of the adjusting block 53 close to the first avoidance cavity 56, preferably 3 counterbores. Screws are provided in the counterbores, and the adjusting block 53 is fixed on the inner side surface of the second swing arm 52 through the screws; at the same time, a second avoidance cavity 57 is provided upward on the lower bottom surface of the fixing plate 51. Pin holes are provided through both sides of the second avoidance cavity 57. A fish-eye ball head 71 is installed in the second avoidance cavity 57. The shaft hole 58 of the fish-eye ball head 71 is aligned with the pin holes, and the fish-eye ball head 71 is fixed in the second avoidance cavity 57 through a pin. The telescopic end of the air cylinder 7 is connected to the fish-eye ball head 71 and drives the adjusting mechanism 5 to perform an up-and-down swing motion.
[0046] Specifically, as Figure 2 shown, a groove is provided upward on the lower bottom surface of the first swing arm 4. A fish-eye ball head 71 is provided in the groove. An installation bracket 41 is fixedly installed outside the groove. The fish-eye ball head 71 is fixed in the groove by a pin passing through the installation bracket 41 and the shaft hole 58 of the fish-eye ball head 71. The telescopic end of the air cylinder 7 is connected to the fish-eye ball head 71 and drives the first swing arm 4 to perform an up-and-down swing motion.
[0047] In this embodiment, as Figure 2 and Figure 7As shown in the figure, in order to facilitate the disassembly and assembly of the guide roller 2, openings are provided in the radial directions of the shaft holes 58 of the first swing arm 4 and the fixing plate 51, and a plurality of counterbores, preferably two counterbores, are provided on the upper end surfaces of the first swing arm 4 and the fixing plate 51. Screws are provided in the counterbores. The first swing arm 4 and the fixing plate 51 are locked to the guide roller 2 through the screws. When the guide roller 2 needs to be disassembled, the screws in the counterbores are loosened, and the openings open under the action of the resilience force, that is, the shaft hole 58 and the guide roller 2 are in a loose state. In order to ensure the stability of the first swing arm 4 and the fixing plate 51 while providing openings in their radial directions, circular through holes are provided at the bottoms of the openings.
[0048] In this embodiment, when the levelness of the winding roller 3 needs to be adjusted, first, two cylinders 7 are used to perform a large-range adjustment, and then precise adjustment is performed through the upper adjustment screw 54 and the lower adjustment screw 55 on the adjustment mechanism 5. This adjustable foil winding mechanism can precisely adjust the levelness of the winding roller 3, ensure the tightness of the coil during the foil winding operation, reduce the phenomena of looseness and folding, and ensure the quality and stability of the coil.
[0049] The above is only a preferred embodiment of the present invention, and it does not impose any form of limitation on the present invention. Although the present invention is disclosed above in a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art, without departing from the scope of the technical solution of the present invention, when making some changes or modifications using the above-disclosed technical content into equivalent embodiments of equivalent changes, but as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change, and modification made to the above embodiments according to the technical concept of the present invention shall fall within the scope of the technical solution of the present invention.
