Description

Technical Field

[0001] The utility model relates to the field of fresh-keeping bag production, in particular to a rolling track for fresh-keeping bags. Background Art

[0002] Fresh-keeping bags need to go through multiple processes in the production process. First, the material is die-cut and prepared, and then the cut material is passed through a bag-making machine to form a fresh-keeping bag after heating, pressing, and folding. Finally, the finished product is rolled up. The existing winding track will roll the fresh-keeping bag in a serpentine shape during use, and then complete the rolling through continuous transportation. However, in this process, the existing device will not be able to keep the fresh-keeping bag in a taut state due to the problem of conveying and winding, resulting in wrinkles on the surface of the fresh-keeping bag, which will lead to bubbles in the final rolling process, affecting the rolling effect.

[0003] Therefore, a reel track for fresh-keeping bags is now developed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the existing device that the fresh-keeping bag cannot be kept in a tight state due to the problem of conveying and winding, so that wrinkles appear on the surface of the fresh-keeping bag, and then bubbles are present in the final winding process, affecting the winding effect, the utility model provides a winding track for the fresh-keeping bag.

[0005] The technical solution of the utility model is as follows: a winding track for fresh-keeping bags comprises a mounting frame, three groups of mounting seats symmetrically arranged front and back are connected to the upper right side of the mounting frame, a first track roller is slidably connected between the mounting seats on the left and right sides, a second track roller is slidably arranged between the mounting seats in the middle, a fixing rod is connected to the left side of the mounting frame, two groups of adjusting screw rods symmetrically arranged front and back are threadedly connected to the left side of the mounting frame, lifting seats are threadedly connected to the adjusting screw rods, flat ironing parts for low-temperature ironing of fresh-keeping film are connected between the lifting seats symmetrically arranged front and back, a power source is connected to the front side of the upper front of the mounting frame, electric wires are connected between the power source and the flat ironing parts, and a tension adjustment component for pressing the fresh-keeping film is arranged on the left side of the mounting frame.

[0006] As an improvement of the above solution, it further includes a barrier ring, and two of the barrier rings are slidably connected to the first track roller and the second track roller.

[0007] As an improvement to the above solution, the mounting seats are all L-shaped structures.

[0008] As an improvement of the above solution, the second track roller is a frame-type structure, and both the first track roller and the second track roller are provided with locking nuts.

[0009] As an improvement of the above solution, the adjusting screw rod is provided with a power-assisting rotary handle.

[0010] As an improvement of the above solution, the barrier ring is threadedly connected with an adjusting piece.

[0011] By adopting the above technical solution, the advantages of the utility model are:

[0012] 1. The utility model uses a flat ironing piece to perform low-temperature ironing on the raw materials in the transport state, so that the raw materials can avoid wrinkles. At the same time, the tension adjustment component will also keep the raw materials pressed, so that the raw materials are always in a taut state, which makes the fresh-keeping bag more convenient to roll up, and can also avoid the presence of bubbles inside the raw materials after rolling up, thereby improving the rolling effect.

[0013] 2. In the process of guiding transportation, the utility model can rotate the adjusting piece so that the barrier ring is no longer locked, and then adjust the position of the barrier ring according to the width of the raw material so that the barrier ring can adapt to the raw material and guide it during the raw material transportation process.

[0018] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the present application and are not limited to the scope of the present application. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0019] Example 1

[0020] Fresh-keeping bag rewinding track, such as Figure 1-Figure 3As shown, it includes an installation frame 1, and three groups of installation seats 2 are connected to the upper right side of the installation frame 1, which are symmetrical in front and back. The installation seats 2 are all L-shaped structures. A first track roller 3 is slidably connected between the installation seats 2 on the left and right sides, and a second track roller 4 is slidably arranged between the middle installation seats 2. The second track roller 4 is a frame-shaped structure. The first track roller 3 and the second track roller 4 are both provided with locking nuts. A fixing rod 5 is connected to the left side of the installation frame 1. Two groups of adjusting screw rods 6 are threadedly connected to the left side of the installation frame 1, and the adjusting screw rods 6 are each provided with a power-assisting rotary handle. A lifting seat 7 is threadedly connected to the adjusting screw rods 6, and a flat ironing piece 8 for low-temperature ironing of the cling film is connected between the front and rear symmetrical lifting seats 7. A power supply 9 is connected to the front side of the upper part of the installation frame 1, and electric wires are connected between the power supply 9 and the flat ironing piece 8. A tension adjustment component 10 for pressing the cling film is arranged on the left side of the installation frame 1.

[0021] It should be noted that when the fresh-keeping bags in production are being rolled up, the device can be used for auxiliary operations. First, the raw materials are passed through the fixed rod 5, the tension adjustment component 10, the first track roller 3 and the second track roller 4 in sequence, so that the raw materials are in a serpentine state as a whole. In this process, the height positions of the first track roller 3 and the second track roller 4 can be changed by adjusting the nuts on the first track roller 3 and the second track roller 4 to adapt to the raw material conveying path. Then, the adjusting screw 6 is rotated to adjust the height position of the flat ironing piece 8 so that the bottom of the flat ironing piece 8 can contact the raw material. In the process of raw material conveying, the raw material is pressed by the tension adjustment component 10 to keep the raw material taut. Finally, the raw material is conveyed and rolled up. In this process, the flat ironing piece 8 is started, and the flat ironing piece 8 will iron the raw material at a low temperature to avoid wrinkles, resulting in bubbles after rolling up, which affects the rolling effect.

[0022] Example 2

[0023] On the basis of Example 1, Figure 1 and Figure 3 As shown, a blocking ring 11 is also included. Two blocking rings 11 are slidably connected to the first track roller 3 and the second track roller 4, and an adjusting member 12 is threadedly connected to the blocking ring 11.

[0024] During the guided transportation process, the barrier ring 11 can be no longer locked by rotating the adjusting piece 12, and then the position of the barrier ring 11 can be adjusted according to the width of the raw material so that the barrier ring 11 can adapt to the raw material and guide it during the raw material transportation process.
