Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic packaging bags, in particular to a plastic packaging bag edge-sealing device. Background Technique
[0002] Plastic packaging bags are a common packaging material, usually made of plastic materials such as polyethylene and polypropylene. They are light, durable, moisture-proof, dust-proof, etc., and are widely used in food packaging.
[0003] Existing foods often cannot be eaten up at one time. In order to ensure the tightness of the food, a clamping type edge-sealer has appeared on the market, which is used for sealing and edge-sealing the plastic packaging bags of food.
[0004] There are the following drawbacks in the existing edge-sealing of plastic packaging bags: the existing plastic packaging bag edge-sealing mechanism with clamping type heating has a large friction force when moving after heating and clamping, resulting in low smoothness during the edge-sealing movement and difficult operation of the sealing plate. For this reason, we propose a plastic packaging bag edge-sealing device. Summary of the Invention
[0005] The main purpose of the utility model is to provide a plastic packaging bag edge-sealing device, which can effectively solve the problems in the background technique.
[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0007] A plastic packaging bag edge-sealing device includes a lower plate, an upper pressing plate and a heating roller group, and also includes a sleeve, an inner rod and a spring. The upper pressing plate is located at the top of the lower plate. Installation blocks are fixedly arranged at one ends of the lower plate and the upper pressing plate. A conductive slip ring is installed through the installation block. The heating roller group is respectively arranged on one side of the conductive slip ring.
[0008] Further, the heating roller group includes an electrically heated inner rod and a stainless steel roller sleeve. The stainless steel roller sleeve is sleeved on the periphery of the electrically heated inner rod. The electrically heated inner rod is in close contact with the inner wall of the stainless steel roller sleeve. The end of the stainless steel roller sleeve is installed and connected with the electrically heated inner rod through a bolt. The end of the electrically heated inner rod is fixedly installed with the rotor of the conductive slip ring.
[0009] Further, a sleeve is arranged between the lower plate and the upper pressing plate. An inner rod is inserted into the sleeve. A spring is sleeved on the inner rod. The two ends of the spring are respectively welded and connected with the sleeve and the upper pressing plate. The bottom end of the sleeve is welded and connected with the lower plate.
[0010] Further, storage batteries are installed in the lower plate and the upper pressing plate through bolts. The output end of the storage battery is electrically connected with the input end of the conductive slip ring through a wire.
[0011] Compared with the prior art, the utility model has the following beneficial effects: The assembly composed of the lower plate, the upper pressing plate, the heating roller group, the sleeve, the inner rod and the spring realizes a rolling heating mechanism for the edge sealing of plastic packaging bags. While the heating roller group is heating, it can rotate, so that after the plastic packaging bag is clamped up and down between the heating roller groups on the lower plate and the upper pressing plate, the edge sealing of the plastic packaging bag can be processed by heating while rolling. The edge sealing operation with a rolling structure can greatly reduce the friction during the heat sealing movement, increase the convenience of the edge sealing operation of the plastic packaging bag, and solve the problem that the edge sealing mechanism of the plastic packaging bag with a clamping plate type heating edge sealing has a large friction when heated and clamped and moved, resulting in a low smoothness during the edge sealing movement and a large difficulty in the sealing plate operation.

[0016] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0017] As Figures 1-3 shown, an edge sealing device for a plastic packaging bag includes a lower plate 1, an upper pressing plate 2 and a heating roller group 5, and also includes a sleeve 6, an inner rod 7 and a spring 8. The upper pressing plate 2 is located at the top of the lower plate 1. Mounting blocks 3 are fixedly arranged at one end of the lower plate 1 and the upper pressing plate 2. A conductive slip ring 4 is installed through the mounting block 3. The heating roller groups 5 are respectively arranged on one side of the conductive slip ring 4.
[0018] Among them, the heating roller group 5 includes an electric heating inner rod 501 and a stainless steel roller sleeve 502. The stainless steel roller sleeve 502 is sleeved on the periphery of the electric heating inner rod 501. The electric heating inner rod 501 is in close contact with the inner wall of the stainless steel roller sleeve 502. The end of the stainless steel roller sleeve 502 is installed and connected to the electric heating inner rod 501 through bolts. The end of the electric heating inner rod 501 is fixedly installed with the rotor of the conductive slip ring 4.
[0019] Wherein, a sleeve 6 is arranged between the lower plate 1 and the upper pressing plate 2. An inner rod 7 is inserted into the sleeve 6. A spring 8 is sleeved on the inner rod 7. Two ends of the spring 8 are respectively welded to the sleeve 6 and the upper pressing plate 2. The bottom end of the sleeve 6 is welded to the lower plate 1.
[0020] Wherein, storage batteries 9 are respectively installed in the lower plate 1 and the upper pressing plate 2 through bolts. The output end of the storage battery 9 is electrically connected to the input end of the conductive slip ring 4 through a wire. The output end of the conductive slip ring 4 is electrically connected to the input end of the electric heating inner rod 501 at the corresponding position through a wire. The on-off key of the electric heating inner rod 501 is arranged on one side of the upper pressing plate 2.
[0021] It should be noted that the present utility model is a plastic packaging bag edge-sealing device. During operation, an operator turns on the electric heating inner rod 501 to preheat it first. Then, the plastic packaging bag to be edge-sealed is placed between the heating roller sets 5 of the lower plate 1 and the upper pressing plate 2. Then, the operator presses between the lower plate 1 and the upper pressing plate 2, so that the heating roller sets 5 respectively fit and clamp the positions to be edge-sealed of the plastic packaging bag. Then, the operator moves the heating roller sets 5, so that the heating roller sets 5 at high temperature roll and move on the upper and lower sides of the plastic packaging bag, achieving the effect of heating while rolling. Due to the reason of rolling movement, the frictional resistance during the edge-sealing process of the plastic packaging bag is greatly reduced, the efficiency of heat-sealing edge-sealing is increased, and the operation is simpler.
[0022] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model.
