Description

Technical Field

[0001] The utility model belongs to the technical field of bag making machines, and relates to a hot-cut bag making machine, in particular to a fixing device for the hot-cut bag making machine. Background Art

[0002] A bag making machine is a machine that makes various plastic packaging bags or other material packaging bags. Its processing range is packaging bags of various sizes, thicknesses and specifications of plastics or other materials. Generally speaking, plastic packaging bags are the main products. In the domestic market, this type of bag is very popular and has a wide range of applications. Due to its good transparency, it is also an ideal choice for packaging gifts.

[0003] After searching, it was found that a Chinese patent document discloses a fixing device for a hot-cut bag-making machine [Application Number: CN202321328811.5; Publication Number: CN219927088U]. This fixing device for a hot-cut bag-making machine includes a hot-cut bag-making machine and a material. An adjustment device is installed inside the hot-cut bag-making machine, and material is arranged above the adjustment device. The material is installed in the middle position above the hot-cut bag-making machine. The adjustment device includes a bidirectional threaded rod, a bearing, and a motor. A bidirectional threaded rod is installed inside the hot-cut bag-making machine. One side of the bidirectional threaded rod is connected to the inner wall of the hot-cut bag-making machine through a bearing, and the other side passes through the hot-cut bag-making machine and is connected to the motor. Threaded caps are installed on both sides of the outer wall of the bidirectional threaded rod. A telescopic cylinder is installed above the threaded cap. The upper groove of the telescopic cylinder is at the same level as the upper part of the hot-cut bag-making machine. A telescopic rod is provided inside the telescopic cylinder.

[0004] The hot-cut bag-making machine fixing device disclosed in this patent squeezes the material to the middle position above the hot-cut bag-making machine through a telescopic rod to prevent the material from being offset during processing. However, since the plastic packaging bags are relatively thin, squeezing the plastic bags through the telescopic rod can easily cause the plastic to deform during the hot-cutting process, affecting the processing quality of the plastic bags. In addition, pressing and fixing the plastic bags through rubber blocks is not convenient for continuous processing of the plastic bags in the hot-cut bag-making machine, which reduces the efficiency of hot-cut bag-making of the plastics, the operation remains unchanged, and the practicality is poor. Utility Model Content

[0005] The purpose of this utility model is to address the above-mentioned problems in the existing technology and propose a fixing device for a hot-cut bag-making machine. The technical problem to be solved by this utility model is: how to achieve the limiting and fixing of the plastic bags in the hot-cut bag-making machine during continuous processing.

[0006] The purpose of this utility model can be achieved through the following technical solutions:

[0007] A fixing device for a hot-cut bag-making machine comprises a workbench and a hot-cut bag-making machine body fixed to the surface of the workbench, wherein the surface of the workbench is slidably connected to two symmetrical support plates, and adjustment limit assemblies are provided on both sides of the support plates. The adjustment limit assemblies are lifted and arranged above the workbench, and a rotating rod is rotatably connected between the two adjustment limit assemblies, and the ends of the two rotating rods are fixedly connected;

[0008] The adjustment limit assembly includes a top frame, and the interior of the top frame is rotatably connected to a rotating rod, the outer wall of the rotating rod is fixedly connected to a gear column, and the upper and lower outer walls of the gear column are meshedly connected to a toothed plate, the outer end of the toothed plate is fixedly connected to a mounting frame, and the lower part of the mounting frame is rotatably connected to a guide wheel;

[0009] The tooth plate is slidably connected to the interior of the top frame, and two guide wheels are symmetrically arranged inside the top frame.

[0010] By adopting the above structure, when the plastic bag moves under the hot-cutting bag-making machine body through the worktable, the plastic bag is continuously moved on the surface of the worktable. By setting an adjustment limit assembly on the surface of the worktable for lifting and lowering, the height of the adjustment limit assembly is adjusted on the surface of the worktable, which is convenient for the guide wheel to fit the surface of the plastic bag. Considering the applicability of the guide wheel to plastic bags of different sizes, a rotating rod is rotatably connected to the inside of the top frame. Under the action of the gear column fixedly connected to the outer wall of the rotating rod, the gear plate is engaged with the outer wall of the gear column, and the gear column drives the upper and lower gear plates to move synchronously towards or away from each other, so that the gear plate drives the mounting frames on both sides to adjust the distance synchronously, which is convenient for the mounting frame to drive the bottom guide wheels to fit the two side surfaces of the plastic bag. Moreover, the guide wheel is rotatably arranged under the mounting frame, so that when the plastic bag is continuously hot-cut under the hot-cutting bag-making machine body, the guide wheel rotates synchronously on the surface of the plastic bag, realizing stable movement and guidance of the plastic bag on the surface of the worktable, ensuring the hot cutting efficiency of the plastic bag, and the structure is simple and the applicability is wide.

[0011] The bottom ends of both ends of the top frame are fixedly connected with the output ends of the telescopic rods, and the telescopic rods are fixedly installed on the surface of the workbench.

[0012] By adopting the above structure, the telescopic rod drives the top frame to move up and down on the surface of the workbench, which facilitates the height adjustment of the limit assembly on the surface of the workbench, ensures that the guide wheel fits and guides the surface of the plastic bag, and realizes the stable movement of the plastic bag under the machine body.

[0013] The outer wall of the tooth plate is fixedly connected with a sliding column, and the sliding column is slidably connected to the inner wall of the sliding groove, and the sliding groove penetrates and is opened on the side wall of the top frame.

[0014] By adopting the above structure, by fixing the sliding column on the outer wall of the tooth plate, the tooth plate can synchronously drive the sliding column to slide inside the top frame when it moves, so that the tooth plate can move accurately inside the top frame, making it easier for the tooth plate to drive the mounting frame to move accurately.

[0015] A through hole for accommodating the tooth plate is formed in the interior of the mounting frame, and the tooth plate is arranged parallel to the upper and lower ends of the gear column.

[0016] With the above structure, by providing a through hole inside the mounting frame, when the tooth plate on the outer wall of the gear column is telescopically movable, the tooth plate can be telescopically movable inside the mounting frame, thereby avoiding interference of the mounting frame with the tooth plate and ensuring the adjustment effect of the guide wheel driven by the mounting frame.

[0017] A plurality of magnetic plugging posts are fixedly connected to the bottom end of the support plate, and the magnetic plugging posts are magnetically plugged into the inner wall of the magnetic slide, and the magnetic slide is opened on the surface of the workbench.

[0018] By adopting the above structure, the support plate can be inserted and limited inside the magnetic slide through the magnetic plug-in column, so that the support plate can be flexibly installed on the surface of the workbench, making it convenient for the support plate to fix and limit plastic bags of different widths, thereby improving the flexibility of the device, and making it simple to operate and low in maintenance cost.

[0019] The support plates are symmetrically arranged on the surface of the workbench in an L-shaped structure.

[0020] By adopting the above structure, the support plates on both sides can effectively limit the plastic bags during hot cutting processing, thereby achieving the limiting effect of the plastic bags on both sides. Moreover, through flexible adjustment of the support plates, the problem of deformation of the plastic bags caused by the small distance between the support plates is avoided, thereby ensuring the processing accuracy of the plastic bags.

[0021] Compared with the existing technology, the fixing device of the hot-cut bag-making machine of the utility model has the following advantages:

[0022] 1. In the utility model, by arranging two adjustment limit assemblies on the surface of the workbench, the adjustment limit assemblies can perform pressure contact and position limiting on the surface of the continuously processed plastic bag on the surface of the workbench. At the same time, under the rotation of the guide wheel, the pressure contact on the plastic bag during processing is avoided, the continuous movement effect of the plastic bag is ensured, and the processing efficiency of the plastic bag is ensured. Moreover, by synchronously connecting the two adjustment limit assemblies through the rotating rod, it is convenient to synchronously adjust the two adjustment limit assemblies through the rotating rod, thereby ensuring the synchronization of the adjustment of the guide wheel on the surface of the workbench, facilitating the accurate and efficient limiting and fixing of the plastic bag, and the operation is simple and practical.

[0023] 2. In the present invention, by magnetically plugging a support plate on the surface of the workbench, the "L"-shaped support plate can limit the moving plastic bags on both sides, and by flexibly adjusting the support plate, the support plate can be flexibly installed on the surface of the workbench, making it convenient for the support plate to fix and limit plastic bags of different widths, avoiding the problem of deformation of the plastic bags caused by the small distance between the support plates.

[0030] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0031] Example

[0032] like Figures 1-4 As shown;

[0033] A fixing device for a hot-cut bag-making machine comprises a workbench 1, a hot-cut bag-making machine body 2 fixed on the surface of the workbench 1, a backing plate 3, a telescopic rod 4, a top frame 5, a rotating rod 6, a gear column 7, a tooth plate 8, a mounting frame 9, a guide wheel 10, a slide column 11, a slide groove 12, a magnetic slideway 13 and a plug column 14. The surface of the workbench 1 is slidably connected to two symmetrical backing plates 3. Specifically, the backing plates 3 are symmetrically arranged in an "L"-shaped structure on the surface of the workbench 1, so that the backing plates 3 on both sides can well limit the plastic bags during hot cutting processing, thereby achieving a limiting effect on the plastic bags on both sides. At the same time, considering the flexibility of adjusting the backing plates 3 on the surface of the workbench 1, A plurality of magnetic plugs 14 are fixedly connected to the bottom end of the support plate 3, and the magnetic plugs 14 are magnetically plugged into the inner wall of the magnetic slide 13, which is convenient for adjusting the position of the support plate 3. In addition, the magnetic slide 13 is opened on the surface of the workbench 1. Considering the adjustment accuracy of the support plate 3, scale lines can be provided on the surface of the magnetic slide 13 to facilitate precise adjustment of the support plate 3. Through such an arrangement, the support plate 3 can be limited by the internal insertion of the magnetic slide 13 through the magnetic plugs 14, so that the support plate 3 can be flexibly installed on the surface of the workbench 1, which is convenient for the support plate 3 to fix and limit plastic bags of different widths, thereby improving the flexibility of the device.

By fixing the sliding column 11 on the outer wall of the toothed plate 8, the toothed plate 8 is synchronously driven to slide the sliding column 11 inside the top frame 5 when it moves, so that the toothed plate 8 can move accurately inside the top frame 5. At the same time, a mounting bracket 9 is fixedly connected to the outer end of the toothed plate 8, so that the toothed plate 8 can drive the mounting bracket 9 to move accurately, and the interior of the mounting bracket 9 is penetrated by a slot that can accommodate the toothed plate 8 to pass through. Through hole, and the tooth plate 8 is arranged parallel to the upper and lower ends of the gear column 7.

At the same time, a guide wheel 10 is rotatably connected to the lower part of the mounting frame 9, and two guide wheels 10 are symmetrically arranged inside the top frame 5. Through such an arrangement, the adjustment effect of the guide wheel 10 driven by the mounting frame 9 is ensured, so that when the plastic bag is continuously hot-cut under the hot-cut bag-making machine body 2, the guide wheel 10 rotates synchronously on the surface of the plastic bag, so that the guide wheel 10 guides the stable movement of the plastic bag on the surface of the workbench 1 above the plastic bag.

[0036] The working principle of the present invention is as follows: when the hot-cut bag-making machine body 2 is working, the processed plastic bags are moved on the surface of the workbench 1 through the conveyor rollers, so that the plastic bags are continuously moved on the surface of the workbench 1. By providing a magnetic slide 13 on the surface of the workbench 1 and magnetically plugging a magnetic plug 14 inside the magnetic slide 13, the surface of the workbench 1 can be flexibly provided with a support plate 3, so that the support plate 3 can limit the continuously processed plastic bags on both sides, so that the plastic bags can move between the two support plates 3. At the same time, considering the limiting effect on the plastic bags, the telescopic rod 4 is fixedly connected to the surface of the workbench 1, and the top of the telescopic rod 4 is fixedly connected to the adjusting limit assembly. Then, the two adjusting limit assemblies are adjusted in height on the surface of the workbench 1, so that it is suitable for plastic bags of different thicknesses, so that the guide wheel 10 at the bottom of the top frame 5 fits the surface of the plastic bag. The cam 7 is connected with the upper and lower gear plates 8 by the gear column 7, and the gear column 7 drives the upper and lower gear plates 8 to move synchronously toward or away from each other, so that the gear plates 8 drive the mounting frames 9 on both sides to adjust the distance synchronously, so that the mounting frames 9 drive the guide wheels 10 at the bottom to fit the two side surfaces of the plastic bag. Moreover, the guide wheels 10 are rotated under the mounting frames 9, so that when the plastic bag is continuously hot-cut under the hot-cut bag-making machine body 2, the guide wheels 10 rotate synchronously on the surface of the plastic bag, thereby realizing the stable movement and guidance of the plastic bag on the surface of the workbench 1, ensuring the hot-cutting efficiency of the plastic bag, and having a simple structure and wide applicability.
