Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal surface heat treatment and quenching technology, and in particular to a mechanism for preventing misalignment during unwinding of composite packaging bag substrate. Background Technology
[0002] In the production of composite packaging bags, the rolled substrate is unwound from the unwinding station. Due to defects in the master roll itself, installation errors, and tension changes during high-speed operation, the substrate is prone to lateral deviation. Deviation can lead to quality defects such as misalignment, wrinkling, and edge tearing, requiring frequent speed reductions or machine stops for adjustment, which severely restricts production efficiency and product yield.
[0003] Existing technologies generally employ automatic alignment systems, which use sensors to detect edges and then a controller to drive an actuator for adjustment. However, these systems have significant shortcomings: First, existing alignment systems cannot correct the entire substrate, causing the substrate to gradually shift during the correction process; second, the overall structure is often complex and bulky, occupying a large space, and initial debugging is inconvenient. Utility Model Content
[0004] The purpose of this utility model is to provide a mechanism for preventing misalignment during unwinding of composite packaging bag substrate, which can solve at least one of the above-mentioned technical problems. The technical solution of this utility model is as follows: A composite packaging bag substrate unwinding anti-deviation mechanism includes: symmetrically arranged support frames; a fixed seat fixed above each support frame; an unwinding component between the upper parts of each support frame; a clamping guide between the lower parts of each support frame; a tension adjustment part located in front of the clamping guide and between each support frame; a material guide part located in front of the tension adjustment part; a first adjustment mechanism above one of the support frames capable of driving the unwinding component to adjust laterally; and a second adjustment mechanism below one of the support frames capable of driving the clamping guide and the material guide part to adjust laterally synchronously.
[0005] Furthermore, the unwinding component includes a bearing seat fixed on a fixed base, an insert shaft is movably sleeved between each of the bearing seats, an unwinding wheel frame is inserted into the insert shaft, a drive motor is fixed on one of the fixed bases, and the output end of the drive motor is fixedly connected to the sleeved end of the insert shaft.
[0006] Furthermore, the clamping guide includes a first connecting plate disposed between the lower parts of each of the support frames, clamping rollers are symmetrically arranged on the first connecting plate, and a first insertion seat is fixed between the lower parts of each of the support frames, with the upper and lower sides of the first connecting plate movably inserted into the first insertion seat.
[0007] Furthermore, the tension adjustment part includes a guide rail fixed on one of the support frames, a pneumatic slide is inserted into the guide rail, and an adjustment roller is movably sleeved on the pneumatic slide.
[0008] Furthermore, the material guiding part includes a plurality of guide rollers symmetrically arranged in front of the adjusting roller and between each support frame. An extension plate is sleeved on the end of each guide roller. A second connecting plate is connected and fixed between each extension plate. A second insertion seat is fixed between the lower sides of each support frame. The upper and lower sides of the second connecting plate are movably inserted into the second insertion seat.
[0009] Furthermore, the first adjusting mechanism includes a first motor fixed on another fixed base, a first spur gear fixed at the output end of the first motor, a movable plate longitudinally inserted into the other fixed base, a first threaded sleeve provided on the right side of the movable plate, an annular slide rail provided on the right side of the unwinding wheel frame, a slider movably inserted into the annular slide rail, a connecting rod hinged between the slider and the movable plate, a first screw capable of threadedly engaging with the first threaded sleeve being longitudinally movably sleeved on the other fixed base, and a second spur gear capable of meshing with the first spur gear being fixed at the sleeved end of the first screw.
[0010] Furthermore, the second adjustment mechanism includes a second motor fixed on another support frame, a third spur gear fixed at the output end of the second motor, a second screw sleeved in the middle of the second connector, a second threaded sleeve in the middle of the second connecting plate that can thread-mate with the second screw, and a fourth spur gear fixed at the right end of the second screw that can mesh with the third spur gear.
[0011] In summary, the advantages of this utility model over the prior art are: This utility model provides a composite packaging bag substrate unwinding and anti-deviation mechanism. In use, the user places the substrate roll on the unwinding component, and then sequentially places the substrate onto the clamping guide, tension adjustment part, and material guide part. At this time, the unwinding component releases the substrate. During the unwinding process, the clamping guide part clamps and conveys the substrate. At the same time, the tension adjustment part can adjust the tension of the substrate during conveying. Finally, the material guide part guides the substrate to the next processing point. When the substrate conveying deviates, the first adjustment mechanism can drive the unwinding component to adjust laterally, and the second adjustment mechanism can drive the clamping guide and material guide part to adjust laterally simultaneously. Compared with the prior art, it can correct the substrate as a whole. In addition, the overall structure is often simple and occupies little space. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1 to 4 The composite packaging bag substrate unwinding and anti-deviation mechanism shown is characterized by comprising: symmetrically arranged support frames 1, a fixing seat 2 fixed above each support frame 1, an unwinding component 3 provided between each support frame 1 above, a clamping guide 4 provided between each support frame 1 below, a tension adjustment part 5 provided in front of the clamping guide 4 and located between each support frame 1, a material guide part 6 provided in front of the tension adjustment part 5, a first adjustment mechanism 7 provided above one of the support frames 1 capable of driving the unwinding component 3 to adjust laterally, and a second adjustment mechanism 8 provided below one of the support frames 1 capable of driving the clamping guide 4 and the material guide part 6 to adjust laterally synchronously.
[0018] The above-described composite packaging bag substrate unwinding and anti-deviation mechanism involves the user placing the substrate roll on the unwinding component 3, and then sequentially placing the substrate onto the clamping guide 4, the tension adjustment part 5, and the material guide 6. The unwinding component 3 then unwinds the substrate, while the clamping guide 4 clamps and conveys it during unwinding. Simultaneously, the tension adjustment part 5 adjusts the tension of the substrate during conveying. Finally, the material guide 6 guides the substrate to the next processing location. If the substrate deviates during conveying, the first adjustment mechanism 7 drives the unwinding component 3 to adjust laterally, and the second adjustment mechanism 8 simultaneously drives the clamping guide 4 and the material guide 6 to adjust laterally. Compared to existing technologies, this mechanism can correct the substrate as a whole. Furthermore, the overall structure is often simple and occupies little space.
[0019] like Figure 4 As shown, in some embodiments of this utility model, the unwinding component 3 includes a bearing seat 31 fixed on a fixed base 2, and an insertion shaft 32 is movably sleeved between each of the bearing seats 31. An unwinding wheel frame 33 is inserted into the insertion shaft 32. A drive motor 34 is fixed on one of the fixed bases 2. The output end of the drive motor 34 is fixedly connected to the sleeved end of the insertion shaft 32. When the user places the substrate roll on the unwinding wheel frame 33, the drive motor 34 fixed on one of the fixed bases 2 drives the insertion shaft 32 to rotate. At this time, the insertion shaft 32 drives the unwinding wheel frame 33 inserted thereon to rotate.
[0020] like Figure 3 As shown, in some embodiments of this utility model, the clamping guide part 4 includes a first connecting plate 41 disposed between the lower parts of each of the support frames 1, clamping rollers 42 are symmetrically arranged on the first connecting plate 41, and a first insertion seat 43 is fixed between the lower parts of each of the support frames 1. The upper and lower sides of the first connecting plate 41 are movably inserted into the first insertion seat 43. The substrate is clamped, rotated, guided and transported by the clamping rollers 42 symmetrically arranged on the first connecting plate 41. When the first adjusting mechanism 7 is driven, the first connecting plate 41 moves laterally along the first insertion seat 43, so that the substrate clamped between the clamping rollers 42 moves laterally.
[0021] like Figure 4 As shown, in some embodiments of this utility model, the tension adjustment part 5 includes a guide rail 51 fixed on one of the support frames 1, a pneumatic slide 53 inserted into the guide rail 51, and an adjusting roller 54 movably sleeved on the pneumatic slide 53. The substrate being conveyed is sleeved on the adjusting roller 54. At this time, the pneumatic slide 53 can move along the guide rail 51, and the adjusting roller 54 on the pneumatic slide 53 drives the substrate to adjust the tension longitudinally.
[0022] like Figure 4As shown, in some embodiments of this utility model, the material guiding part 6 includes a plurality of guide rollers 61 symmetrically arranged in front of the adjusting roller 54 and between each support frame 1. An extension plate 62 is sleeved on the end of each guide roller 61. A second connecting plate 63 is connected and fixed between each extension plate 62. A second insertion seat 64 is fixed between the lower sides of each support frame 1. The upper and lower sides of the second connecting plate 63 are movably inserted into the second insertion seat 64. This is used to sleeve the substrate on each guide roller 61. When the first adjusting mechanism 7 is driven, it drives the second connecting plate 63 to move laterally along the second insertion seat 64. At this time, the second connecting plate 63 drives each guide roller 61 to move laterally and adjust through the extension plate 62.
[0023] like Figure 3 As shown, in some embodiments of this utility model, the first adjusting mechanism 7 includes a first motor 71 fixed on another fixed base 2, a first spur gear 72 fixed at the output end of the first motor 71, a moving plate 73 longitudinally inserted into the other fixed base 2, a first threaded sleeve 74 provided on the right side of the moving plate 73, an annular slide rail 75 provided on the right side of the unwinding wheel frame 33, a slider 76 movably inserted into the annular slide rail 75, a connecting rod 77 hinged between the slider 76 and the moving plate 73, and a first threaded sleeve 74 movably sleeved on the other fixed base 2. The first screw 78 is threaded, and a second spur gear 79 that can mesh with the first spur gear 72 is fixed at the sleeve end of the first screw 78. The first motor 71 drives the first spur gear 72 to rotate, so that the first spur gear 72 drives the first screw 78 to rotate through the second spur gear 79. At this time, the first screw 78 drives the moving plate 73 to move downward through the first threaded sleeve 74. The moving plate 73 drives the slider 76 to move through the connecting rod 77. The slider 76 drives the unwinding wheel frame 33 to move along the insertion shaft 32 through the annular slide rail 75. When the unwinding wheel frame 33 rotates, the slider 76 will slide along the annular slide rail 75.
[0024] like Figure 4As shown, in some embodiments of this utility model, the second adjusting mechanism 8 includes a second motor 81 fixed on another support frame 1, a third spur gear 82 fixed at the output end of the second motor 81, a second screw 83 sleeved in the middle of the second plug-in seat 64, a second threaded sleeve 84 in the middle of the second connecting plate 63 that can threadedly engage with the second screw 83, and a fourth spur gear 85 that can mesh with the third spur gear 82 fixed at the right end of the second screw 83. The second motor 81 drives the third spur gear 82 to rotate, which in turn drives the fourth spur gear 85 to rotate. At this time, the fourth spur gear 85 drives the second screw 83 to rotate. The second screw 83 drives the second connecting plate 63 to move along the first plug-in seat 43 through the second threaded sleeve 84. The user can install a fixed connecting component between the first plug-in seat 43 and the second plug-in seat 64 so that the second plug-in seat 64 moves synchronously when the first plug-in seat 43 moves.
