Description

Technical Field

[0001] This utility model relates to the field of express delivery bag production technology, and in particular to a plastic heat-sealing device for producing express delivery bags. Background Technology

[0002] Express delivery bags are bags specifically designed for packaging and transporting goods, commonly used in the express delivery industry. They are generally made of plastic (such as polyethylene, polypropylene, etc.) or other synthetic materials. During the production of express delivery bags, the plastic is sealed at the edges using heat-cutting technology and then cut to the appropriate size to complete the production process.

[0003] A Chinese patent discloses a plastic hot-cutting and sealing device for producing express delivery bags (authorization announcement number CN216001628U). This patented technology uses a combination of a pressure block and an electric heating wire. The pressure block presses the express delivery bag downwards, causing the electric heating wire to heat-melt two sealing strips on the express delivery bag, facilitating the sealing of the express delivery bag. Through the combination of a cutter and a cutting groove, a telescopic cylinder pushes a horizontal plate downwards, causing the cutter to cut the express delivery bag, facilitating the slitting of the express delivery bag and cutting it open from the two sealing strips.

[0004] However, most existing methods for producing plastic heat-sealed express bags involve directly using heating wires for heat melting. After melting, the heat is directly transferred outwards. The temperature at the melted area is high, and without cooling, the plastic is prone to breakage, affecting express bag production. Therefore, those skilled in the art have provided an apparatus for producing plastic heat-sealed express bags to solve the problems mentioned in the background. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a plastic heat-sealing device for producing express delivery bags, which solves the problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a plastic heat-sealing device for producing express bags, comprising a workbench and a support mounted on the upper surface of the workbench. A heat-sealing table is fixed inside the support on the upper surface of the workbench. A second electric lifting rod is mounted on the upper surface of the support. A second lifting plate is connected to the telescopic end of the second electric lifting rod. Connecting rods are symmetrically arranged on the lower surface of the second lifting plate. A pressure plate is connected to the lower end of each connecting rod. Heating wires are also symmetrically arranged on the upper surface of the heat-sealing table. A first electric lifting rod is also mounted on the upper surface of the support. A first lifting plate is connected to the telescopic end of the first electric lifting rod. A cutter is mounted on the lower surface of the first lifting plate.

[0007] A cooling box is installed on the lower surface of the workbench, a mounting bracket is installed on the lower surface of the cooling box, a heat dissipation fan is installed on the upper surface of the mounting bracket, a semiconductor cooling chip is installed inside the cooling box, and a heat-conducting rod is installed through the upper surface of the cooling box. A heat-conducting plate is connected to the upper end of the heat-conducting rod near the bracket.

[0008] The upper surface of the bracket is also equipped with a deodorizing box, the inside of which is equipped with an adsorption net, and an exhaust fan is installed inside the deodorizing box above the adsorption net.

[0009] As a further technical solution of this utility model, the upper surface of the second lifting plate is also symmetrically provided with guide rods, the upper end of the guide rods penetrating the upper surface of the bracket.

[0010] As a further technical solution of this utility model, the upper surface of the hot cutting table is also provided with a cutting groove corresponding to the cutting blade, and at least two sets of heating wires are symmetrically arranged on the upper surface of the hot cutting table.

[0011] As a further technical solution of this utility model, the lower surface of the deodorizing box is symmetrically provided with connecting pipes, the lower end of the connecting pipes is connected to an air inlet pipe, the lower surface of the air inlet pipe is symmetrically provided with air inlet heads, and the upper surface of the deodorizing box is also provided with an exhaust hole.

[0014] This utility model provides a plastic heat-sealing device for producing express delivery bags, which has the following advantages compared with the prior art:

[0015] 1. This design relates to a plastic heat-sealing device for producing express delivery bags. The device uses a semiconductor cooling chip inside the cooling box to cool the water inside, and the energy of the cold water is transferred to the heat-conducting plate through a heat-conducting rod. The heat-conducting plate cools the area after the plastic is heat-sealed, thus preventing the seal from becoming soft and easily loosening or tearing during the heat-melting process, which would affect the subsequent production of express delivery bags. The device has a simple structure and good practicality.

[0016] 2. This design is a plastic heat-sealing device for producing express delivery bags. By operating the exhaust fan inside the deodorizing box, the odor generated by the heat-sealing plastic can be drawn in through the air inlet and enter the deodorizing box through the air inlet pipe and connecting pipe. The odor is then absorbed by the adsorption net, thus preventing the generated odor from causing harm to the surrounding staff. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5This utility model provides a technical solution for a plastic heat-sealing device for producing express delivery bags: it includes a workbench 1 and a support 4 set on the upper surface of the workbench 1. A heat-cutting table 41 is fixed inside the support 4 on the upper surface of the workbench 1. A second electric lifting rod 63 is installed on the upper surface of the support 4. The telescopic end of the second electric lifting rod 63 is connected to a second lifting plate 6. Connecting rods 611 are symmetrically arranged on the lower surface of the second lifting plate 6. A pressure plate 61 is connected to the lower end of the connecting rods 611. Heating wires are also symmetrically arranged on the upper surface of the heat-cutting table 41. The upper surface of the bracket 4 is also provided with a first electric lifting rod 5. The telescopic end of the first electric lifting rod 5 is connected to a first lifting plate 51. A cutter 52 is installed on the lower surface of the first lifting plate 51. The plastic of the production of express bags on the hot cutting table 41 can be melted by using an electric heating wire. The second lifting plate 6 can be raised and lowered by the second electric lifting rod 63, and the two sets of pressure plates 61 can press the plastic on both sides of the electric heating wire downward to ensure its stability. At the same time, the cutter 52 can cut the plastic. The structure is simple and the practicality is good.

[0025] A cooling box 2 is installed on the lower surface of the workbench 1. A mounting bracket 21 is installed on the lower surface of the cooling box 2. A heat dissipation fan 211 is installed on the upper surface of the mounting bracket 21. A semiconductor cooling chip 23 is installed inside the cooling box 2. A heat-conducting rod 24 is installed through the upper surface of the cooling box 2. A heat-conducting plate 22 is connected to the upper end of the heat-conducting rod 24 near the bracket 4. This arrangement allows cold water to be added to the interior of the cooling box 2 through the water inlet pipe on the rear surface. The temperature can be monitored by the temperature sensor inside. The semiconductor cooling chip 23 is energized to cool the cold water, so as to facilitate the subsequent cooling of the hot-melted plastic.

[0026] The upper surface of the bracket 4 is also equipped with a deodorizing box 3. The deodorizing box 3 is equipped with an adsorption net 31 inside, and an exhaust fan 32 is installed above the adsorption net 31 inside the deodorizing box 3. This arrangement uses the exhaust fan 32 inside the deodorizing box 3 to extract the odor generated by the hot melting and put it into the adsorption net 31 for adsorption and filtration.

[0027] like Figure 2 As shown, guide rods 62 are symmetrically arranged on the upper surface of the second lifting plate 6. The upper end of the guide rod 62 penetrates the upper surface of the bracket 4. This arrangement allows the guide rod 62 to guide the second lifting plate 6 when it is raised or lowered, ensuring the stability of the pressure plate 61 pressing down on the plastic.

[0028] like Figure 3 As shown, the upper surface of the hot cutting table 41 is also provided with a cutting groove corresponding to the cutter 52. At least two sets of heating wires are symmetrically arranged on the upper surface of the hot cutting table 41. This arrangement can heat the plastic by energizing the heating wires, and at the same time, the cutter 52 can be used to seal the plastic at the edges.

[0029] like Figure 5 As shown, the lower surface of the deodorizing box 3 is symmetrically provided with connecting pipes 341, the lower end of which is connected to an air inlet pipe 34. The lower surface of the air inlet pipe 34 is symmetrically provided with air inlet heads 342. The upper surface of the deodorizing box 3 is also provided with an exhaust hole 33. This arrangement utilizes the exhaust fan 32 inside the deodorizing box 3 to allow the air generated by the hot melting to enter the air inlet pipe 34 through the air inlet head 342, and finally enter the deodorizing box 3 through the connecting pipe 341. After entering, the air is adsorbed by the adsorption net 31 to prevent the irritating odor generated by the hot melting from harming the surrounding people.

[0030] like Figure 4 As shown, the hot end of the thermoelectric cooler 23 is located on the lower surface of the cooling box 2, and the cold end of the thermoelectric cooler 23 is located inside the cooling box 2. At least four heat-conducting rods 24 are symmetrically arranged inside the cooling box 2. The upper surface of the heat-conducting plate 22 is flush with the upper surface of the workbench 1. This arrangement uses the thermoelectric cooler 23 to cool the cold water inside the cooling box 2, and the heat-conducting rods 24 can conduct the energy of the cold water to the heat-conducting plate 22. The heat-conducting plate 22 can be used to cool the hot-melt position to prevent it from breaking due to high temperature after hot melting, which would affect the quality.

[0031] The working principle of this utility model is as follows: When using the plastic hot-cutting and sealing device for producing express bags, the plastic to be hot-cut and sealed is first transported to the hot-cutting table 41 in the bracket 4 by external equipment. The second electric lifting rod 63 can raise and lower the second lifting plate 6, and the two sets of pressure plates 61 press down on the plastic on both sides of the heating wire. After pressing, the plastic is hot-melted by the heating wire. The first electric lifting rod 5 can be activated to raise and lower the first lifting plate 51. During the raising and lowering, the cutter 52 can be lowered to achieve the purpose of cutting. After cutting, it is conveyed out by an external conveyor belt. At the same time as cutting, the exhaust fan 32 inside the deodorizing box 3 works, so that the air generated by hot melting enters the air intake pipe through the air intake head 342. In section 34, the plastic finally enters the deodorizing box 3 through the connecting pipe 341, and is then adsorbed by the adsorption net 31 to prevent the irritating odor generated by the hot melting from harming the surrounding people. During the transfer, the hot-melt part of the plastic falls onto the heat-conducting plate 22, which can transfer the energy of the cold water inside the cooling box 2 to the heat-conducting plate 22 through the heat-conducting rod 24. In this way, the heat-conducting plate 22 can cool the hot-melt part of the plastic, which can prevent the seal from being in a softened state during the hot melting process, which is easy to loosen or tear, affecting the subsequent production of express bags. For details on how the plastic is transferred, how it is hot-cut and sealed, and how it is transferred out, please refer to the content of patent CN216001628U, which is prior art and will not be discussed in detail here.

[0032] The cooling fan, semiconductor refrigeration chip, exhaust fan, first electric lifting rod, and second electric lifting rod used in this utility model are all existing known electrical devices. They are all connected to an external main controller and power supply. The main controller can be a conventional known device such as a computer, and all of them can be purchased and used directly on the market. Their structure, circuit, and control principle are all existing known technologies. Therefore, the structure, circuit, and control principle of the device will not be described in detail here.

[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
