Description

Technical Field

[0001] This utility model relates to the field of multi-layer sheet processing technology, specifically a multi-layer sheet composite tension adjustment device. Background Technology

[0002] Multilayer sheet lamination refers to the technology of combining films of different materials, such as an outer film, multiple barrier films, and an inner film, to achieve effective physical properties and chemical resistance. These composite sheets can be used to produce packaging products, such as composite hoses. The barrier layers of multilayer barrier films include EVOH layers, polyamide layers, etc., and the combination of these layers can improve the film's barrier properties, strength, stiffness, abrasion resistance, and chemical resistance. However, during the lamination of multilayer sheets, unevenness can occur due to inconsistent tension between the layers. Therefore, a multilayer sheet lamination tension adjustment device is needed to adjust the tension between the multiple layers.

[0003] There are many types of such devices on the market today, which can basically meet people's needs, but there are still some problems: when adjusting the tension of multi-layer sheet composites, tension adjustment is usually achieved by extruding at one point, but this method makes the tension adjustment of multi-layer sheets poor, which makes the subsequent multi-layer sheet composite effect unsatisfactory, resulting in wrinkles in the multi-layer sheet composite. Utility Model Content

[0004] The purpose of this invention is to provide a multi-layer sheet composite tension adjustment device to solve the problem in the background art where the tension adjustment of multi-layer sheet composite is usually achieved by extruding at one point, but this method results in poor tension adjustment of multi-layer sheets, which leads to the failure to achieve the desired composite effect and the continued occurrence of wrinkles in the multi-layer sheet composite.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer sheet composite tension adjustment device, comprising: a horizontal plate, with support legs fixed on both sides of the bottom end of the horizontal plate, a second bearing shaft provided at one end between the two horizontal plates, and a first bearing shaft provided at the end between the two horizontal plates away from the second bearing shaft, the horizontal plate, support legs, first bearing shaft and second bearing shaft forming a bracket, a first gear rotatably mounted on the horizontal plate, a second gear meshing with the first gear rotatably mounted on the horizontal plate, a second vertical frame provided on the side of the two first gears close to each other, a first vertical frame provided on the side of the two second gears close to each other, a tension shaft fixed between the two first vertical frames and between the two second vertical frames, a mounting base provided on the outer wall of the horizontal plate, a servo motor mounted at one end of the mounting base, and the output end of the servo motor connected to one end of the first gear.

[0006] Preferably, there are three first bearing shafts, which are arranged in a stepped manner.

[0007] Preferably, a U-shaped groove is provided on both the first vertical frame and the second vertical frame, and a clamping shaft is installed in the U-shaped groove by rotating through a short shaft, and the clamping shaft and the tension shaft are arranged in parallel.

[0008] Preferably, an embedding groove is provided on both the first vertical frame and the second vertical frame, and a screw hole is vertically provided at the middle position of the embedding groove. A screw is threaded through one end of the clamping shaft, and the screw is threadedly connected to the first vertical frame or the second vertical frame.

[0009] Preferably, a through cylinder is sleeved on the clamping shaft, and a limiting plate is integrally connected to one side of the through cylinder, and the limiting plate and the clamping shaft are connected laterally through the shaft.

[0010] Preferably, the limiting plate has a slot at one end near the tension shaft, and the slot is U-shaped, and the width of the clamping shaft is greater than the diameter of the tension shaft.

[0011] Preferably, a tensioning pin is vertically inserted through the cylinder, and the tensioning pin is L-shaped.

[0012] Preferably, multiple threaded holes are equally spaced at the top of the clamping shaft, and the clamping pin and the clamping shaft are connected by threads through the threaded holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: First, the servo motor output shaft drives the first gear to rotate, which in turn drives the first vertical frame to rotate. Since the first gear and the second gear are meshed, the second vertical frame is rotated at the same time. At this time, the tension of the multi-layer sheet can be adjusted at two points using the two clamping shafts, which improves the tension effect during the multi-layer sheet composite process and avoids wrinkling problems. Second, the movement of the limiting plate is used to adjust the multi-layer sheet that is undergoing tension adjustment and limit its movement, so as to prevent the multi-layer sheet from shifting and affecting the overall effect.

[0024] Example 1

[0025] Please see Figure 1-5The present invention provides an embodiment of a multi-layer sheet composite tension adjustment device, comprising: a horizontal plate 1, two support legs 2, both of which are welded and fixed to the left and right sides of the horizontal plate 1, both ends of a second bearing shaft 4 being fixed together to one side between the two horizontal plates 1, and a first bearing shaft 3 being fixed to a fixed frame on the two horizontal plates 1 by welding technology. The horizontal plate 1, support legs 2, first bearing shaft 3 and second bearing shaft 4 form a support. The first gear 10 rotates on the horizontal plate 1. Short shafts at both ends of the first gear 10 pass through the horizontal plate 1, allowing it to rotatably mount on the horizontal plate 1 via these short shafts. Similarly, the second gear 11 is rotatably mounted on the horizontal plate 1 via short shafts, located to one side of the first gear 10. The second gear 11 and the first gear 10 are meshed together. During the rotation of the first gear 10, the second gear 11 is driven to rotate, thus transmitting force. Two second vertical supports 12 are provided, each fixed to the short shafts of the first gear 10 at one end of the two horizontal plates 1. Two first vertical supports 7 are provided, each fixed to the short shafts of the second gear 11 at one end of the two horizontal plates 1. Two tension shafts 8 are provided, each... Located between the two first vertical supports 7 and the two second vertical supports 12, the tension shaft 8 and the first vertical supports 7 or the tension shaft 8 and the second vertical supports 12 are arranged in a U-shape. The sheet material is then wound around the surface of the tension shaft 8, with the sheet material arranged at an angle on the two tension shafts 8. The sheet material is wound through the upper surface of the tension shaft 8 between the two first vertical supports 7, and then through the lower surface of the clamping shaft 9 between the two second vertical supports 12, forming a Z-shape. The mounting base 5 is fixed to one end of one of the horizontal plates 1 by welding technology. The mounting base 5 has a circular through hole. The servo motor 6 is mounted on the mounting base 5 by threaded screws. The output shaft of the servo motor 6 is connected to one end of the first gear 10 by existing technology. When the servo motor 6 operates, the rotating shaft on the servo motor 6 drives the first gear 10 to start rotating. There are three first bearing shafts 3, which are arranged in a stepped manner. At this point, the three-layer sheet can be wound around the bottom end of the first bearing shaft 3 and then around to the upper surface of the tension shaft 8 between the two first vertical frames 7, at which point the sheet forms a Z-shaped state; one of the first vertical frames 7 and the second vertical frame 12 are provided with U-shaped grooves, and one end of the clamping shaft 9 is installed on the first vertical frame 7 or the second vertical frame 12 through a short shaft. At this point, the clamping shaft 9 can rotate at multiple angles on the first vertical frame 7 or the second vertical frame 12 by utilizing the action of the short shaft, and the clamping shaft 9 and the tension shaft 8 are set in parallel.

[0026] Example 2

[0027] Please see Figure 1-5A multi-layer sheet composite tension adjustment device is disclosed. An embedding groove 13 is provided on one of the first vertical supports 7 or the second vertical supports 12. The embedding groove 13 is U-shaped, and a screw hole is vertically provided in the middle of the embedding groove 13. A screw 14 is threadedly installed on a clamping shaft 9, and the screw 14 and the first vertical support 7 or the second vertical support 12 are threadedly connected. The clamping shaft 9 and the first vertical support 7 or the clamping shaft 9 and the second vertical support 12 are connected and fixed between the screw 14 and the screw hole in the embedding groove 13. The sheet is located between the clamping shaft 9 and the tension shaft 8, and the tension shaft 8 and the clamping shaft 9 provide a limiting function for the sheet. A through cylinder 16 is sleeved on the clamping shaft 9, and a limiting plate 15 is fixed to one side of the through cylinder 16 by welding. The through cylinder 16 and the limiting plate 15 are integrated, and the limiting plate 15 and the clamping shaft 9 are horizontally connected. During subsequent use, the sheet material is limited in width by the limiting plate 15, preventing it from moving within the width range and ensuring the flatness of multiple sheet composites. A slot 19 is provided at one end of the limiting plate 15 near the tension shaft 8, and the slot 19 is inverted U-shaped. The width of the clamping shaft 9 is greater than the diameter of the tension shaft 8. One end of the limiting plate 15 is mounted on the tension shaft 8. The slot 19 ensures smooth movement of the limiting plate 15 on the tension shaft 8. Since the bottom end of the limiting plate 15 is in the slot 19 position, the tension shaft 8 and the slot 19 do not obstruct the rotation of the clamping shaft 9. A tensioning pin 17 is vertically inserted through the through cylinder 16, and the tensioning pin 17 is L-shaped. Multiple threaded holes 18 are evenly spaced at the top of the clamping shaft 9, and the tensioning pin 17 and the clamping shaft 9 are connected by threads through the threaded holes 18. By having threaded holes 18 evenly spaced up and down on the clamping shaft 9, the clamping pin 17 can be connected to multiple threaded holes 18, and the position of the limiting plate 15 can be reasonably adjusted according to the width of the sheet.

[0028] Working principle: When in use, firstly, the multi-layer sheet is wound out from the bottom end of the first bearing shaft 3 as needed and placed on the clamping shaft 9 on the second vertical frame 12. Then, it is wound out from the tension shaft 8 on the second vertical frame 12 from the side close to the first bearing shaft 3 and then wound onto the second bearing shaft 4.

[0029] Next, rotate the tension pin 17 to pull the limiting plate 15 to the appropriate position. Then, rotate the tension pin 17 into the threaded hole 18 and adjust the limiting plate 15 to the required position.

[0030] Finally, when the tension of the sheet needs to be adjusted, the servo motor 6 is started. The output shaft of the servo motor 6 drives the first gear 10 to rotate. At the same time as the first gear 10 rotates, it actuates the second gear 11 to rotate, adjusting the angle between the first vertical frame 7 and the second vertical frame 12. When the angle between the first vertical frame 7 and the second vertical frame 12 is larger, the maximum tension adjustment of the sheet is performed. When the angle between the first vertical frame 7 and the second vertical frame 12 is smaller, the tension adjustment force of the sheet is smaller. Finally, the use of the multi-layer sheet composite tension adjustment device is completed.
