Description

Technical Field

[0001] The utility model relates to the technical field of powder packaging sealing, in particular to a sealing device for packaging metal powder. Background Technique

[0002] Metal powder may be contaminated by air, moisture, chemicals or other pollutants during storage and transportation. Appropriate packaging can prevent these external factors from entering the interior of the package, thereby maintaining the purity and quality of the metal powder. A metal powder packaging bag sealing device is a device used to seal metal powder packaging bags to ensure the safety and stability of the powder during storage and transportation.

[0003] In the prior art, the packaging bag of metal powder uses the principle of heating to seal the opening. After the sealing treatment, the temperature of the material at the sealing part is relatively high and it takes a certain amount of time to cool down. Most of the production processes will choose the following several cooling methods: placing the sealed packaging bag at room temperature and allowing it to gradually cool in the natural environment, or using a fan and air-cooling equipment to blow air on the sealing area to accelerate heat dissipation. In the first natural cooling method, the cooling speed is affected by various factors such as the ambient temperature, the heat conduction performance of the packaging material, and the sealing area, and it is easy to have a situation where the cooling time at the sealing part is too long and the effect is not good. During the air-cooling process, due to the unevenness of air flow, the temperature distribution in the sealing area is also uneven, thus affecting the sealing quality. Summary of the Invention

[0004] The purpose of the utility model is to provide a sealing device for packaging metal powder to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] It includes a cooling component for helping the sealing part of the packaging bag to cool down. The cooling component is arranged inside the sealing device. The cooling component is composed of a water tank, an inlet circulation pipe, an outlet circulation pipe, a metal connecting pipe, a silicone rubber bag, a connecting piece, a connecting rod and a fixing plate. One side of the water tank is connected with the inlet circulation pipe. One end of the inlet circulation pipe is fixedly connected with the silicone rubber bag. One side of the silicone rubber bag is connected with the metal connecting pipe. One end of the metal connecting pipe is connected with the outlet circulation pipe. One end of the outlet circulation pipe is connected with the water tank. After the silicone rubber bag is filled with an appropriate amount of cold water, it fits with the packaging bag to cool down the sealing part. It solves the problems in the prior art that the cooling speed of the packaging bag is affected by various factors such as the ambient temperature, the heat conduction performance of the packaging material, and the sealing area, resulting in too long cooling time at the sealing part and poor effect, and due to the unevenness of air flow, the temperature distribution in the sealing area is uneven, thus affecting the sealing quality.

[0007] Preferably, a platform is connected below the water tank. On one side above the platform, a conveyor belt is provided for conveying packaging bags. On the other side above the platform, a working box is connected. A sliding groove is provided on one side of the working box, and the opening of the packaging bag slides inside the sliding groove. The packaging bag is placed steadily on the conveyor belt, and the part of the packaging bag that needs to be sealed is inserted into the sliding groove. When the conveyor belt starts, it drives the packaging bag to move horizontally along the sliding groove together.

[0008] Preferably, two second hydraulic rods are connected to one side above the interior of the working box, and the extending ends of the second hydraulic rods are connected to a fixing plate. The second hydraulic rods can drive the fixing plate to move up and down, facilitating the operation and use of the cooling components.

[0009] Preferably, referring to the attached Figure 3 As shown, two first hydraulic rods are connected to the upper and lower sides inside the working box, and the extending ends of the first hydraulic rods are connected to electric heating plates. There is a gap between the two electric heating plates located on the upper and lower sides of the working box, and the gap is used to place the seal of the packaging bag. The two electric heating plates are respectively located in the upper and lower parts of the working box, and the electric heating plates are controlled by the first hydraulic rods. When the packaging bag passes through the gap between the two electric heating plates, the first hydraulic rods on the upper and lower sides respectively control the electric heating plates to move towards the packaging bag, thus forming a clamping action on the sealed part of the packaging bag.

[0010] Preferably, a metal plate is connected below the interior of the working box, and the metal plate is located below the silicone rubber bag. After the sealed part of the packaging bag is heated and sealed, it stays at the position of the metal plate, and the sealed part of the packaging bag adheres to the upper surface of the metal plate.

[0011] Preferably, a water outlet pipe is connected to one side of the water tank. When the water in the water tank has been used for a period of time, open the valve of the water outlet pipe to drain the water inside, and then pour clean water into the bucket again.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] In the present utility model, after the sealing part of the packaging bag is heat-sealed, the packaging bag is moved below the cooling component. At this time, the second hydraulic rod controls the fixed plate to descend. While the fixed plate descends, the silicone rubber bag also descends accordingly until the rubber bag fits onto the upper surface of the packaging bag opening. Among them, before the silicone rubber bag descends, cold water in the water tank is sucked into the silicone rubber bag through the water inlet circulation pipe. By utilizing the fact that silicone rubber has better heat insulation performance, it can effectively maintain the temperature of the water in the bag and extend the cooling time. Therefore, when the silicone rubber bag fits onto the sealing part of the packaging bag, the silicone rubber bag has a certain softness and can completely cover and press the sealing part to achieve the effect of uniform cooling. In this application, the method of using a water-filled silicone rubber bag to cool the packaging bag opening solves the problems in the prior art that the cooling speed of the packaging bag is affected by various factors such as the ambient temperature, the heat conduction performance of the packaging material, and the sealing area, resulting in too long cooling time at the sealing part and poor effect. Due to the uneven air flow, the temperature distribution in the sealing area is uneven, thus affecting the sealing quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Please refer to Figures 1-6 , the present utility model provides a technical solution:

[0026] It includes a cooling component 17 for helping to cool the sealing part of the packaging bag. The cooling component 17 is arranged inside the sealing device. The cooling component 17 is composed of a water tank 5, an inlet circulation pipe 16, an outlet circulation pipe 15, a metal connecting pipe 14, a silicone rubber bag 13, a connecting piece 10, a connecting rod 12, and a fixing plate 11. One side of the water tank 5 is connected with the inlet circulation pipe 16. One end of the inlet circulation pipe 16 is fixedly connected with the silicone rubber bag 13. One side of the silicone rubber bag 13 is connected with the metal connecting pipe 14. One end of the metal connecting pipe 14 is connected with the outlet circulation pipe 15. One end of the outlet circulation pipe 15 is connected with the water tank 5. After the silicone rubber bag 13 is filled with an appropriate amount of cold water, it is attached to the packaging bag to cool the sealing part.

[0027] During use, after the sealing part of the packaging bag is heat-sealed, the packaging bag is moved below the cooling component. At this time, the second hydraulic rod 9 controls the fixed plate 11 to descend. The silicone rubber bag 13 located below the fixed plate 11 is connected to the fixed plate 11 through the connecting pieces 10 and connecting rods 12 on both sides. Therefore, when the fixed plate 11 descends, the silicone rubber bag 13 also descends accordingly until the rubber bag fits onto the upper surface of the packaging bag opening. Among them, before the silicone rubber bag 13 descends, cold water in the water tank 5 is sucked into the silicone rubber bag 13 through the water inlet circulation pipe 16. By utilizing the better heat insulation performance of silicone rubber, it can effectively maintain the temperature of the water in the bag and extend the cooling time. Therefore, when the silicone rubber bag 13 fits to the sealing part of the packaging bag, the silicone rubber bag has a certain softness and can completely cover and press the sealing part to achieve the effect of uniform cooling. After being used repeatedly several times, the water in the bag can be pumped back into the water tank 5 through the water outlet circulation pipe 15, and the replaced water enters the silicone rubber bag 13 again through the water inlet circulation pipe 16 to realize the replacement cycle of water to maintain a lower temperature of the silicone rubber bag 13. And one end of the water outlet circulation pipe 15 is connected with a metal connecting pipe 14. The metal pipe has good heat conduction performance, which is beneficial to the heat dissipation of water. In this way, the best cooling effect can be achieved through such a cycle. Therefore, in this application, the method of using a water-filled silicone rubber bag to cool the packaging bag opening solves the problems in the prior art that the cooling speed of the packaging bag is affected by various factors such as the ambient temperature, the heat conduction performance of the packaging material, and the sealing area, resulting in too long cooling time at the sealing part, poor effect, and uneven temperature distribution in the sealing area due to the uneven air flow, thus affecting the sealing quality.

[0028] In a further preferred embodiment, a platform 1 is connected below the water tank 5. One side above the platform 1 is provided with a conveyor belt 3 for conveying the packaging bag. The other side above the platform 1 is connected with a working box 2. One side of the working box 2 is provided with a sliding groove 4, and the packaging bag opening slides inside the sliding groove 4.

[0029] In this application, before sealing, first orient the side of the packaging bag that needs to be sealed towards the direction of the working box 2, and place the packaging bag steadily above the conveyor belt 3, so that the side of the packaging bag to be sealed is inserted into the sliding groove 4. With the start of the conveyor belt 3, it drives the sealing part of the packaging bag to move horizontally along the direction of the sliding groove 4.

[0030] In a further preferred embodiment, two second hydraulic rods 9 are connected to one side above the interior of the working box 2, and the extending ends of the second hydraulic rods 9 are connected with a fixed plate 11.

[0031] In this application, the second hydraulic rod 9 is mainly provided to control the lifting of the fixed plate 11 and the cooling component 17 below. When the cooling component 17 needs to cool the sealed part of the packaging bag, the second hydraulic rod 9 controls the fixed plate 11 to descend until the silicone rubber bag 13 fits onto the upper surface of the sealed part of the packaging bag.

[0032] In a further preferred embodiment, referring to the attached Figure 3 As shown, two first hydraulic rods 7 are connected to the upper and lower sides inside the working box 2. The extending ends of the first hydraulic rods 7 are connected to electric heating plates 8. There is a gap between the two electric heating plates 8 located on the upper and lower sides of the working box 2, and the sealed part of the packaging bag is placed in the gap.

[0033] In this application, after the electric heating plate 8 is powered on, it can heat itself. When the packaging bag is conveyed by the conveyor belt 3 between the upper and lower electric heating plates 8, the first hydraulic rod 7 is activated to control the electric heating plate 8 to clamp the packaging bag and heat the material at the sealed part to melt it, thereby achieving the purpose of plastic sealing.

[0034] In a further preferred embodiment, a metal plate 18 is connected to the lower part inside the working box 2, and the metal plate 18 is located below the silicone rubber bag 13.

[0035] In this application, the material of the metal plate 18 is a metal material. Since metal has good heat dissipation performance, when the cooling component 17 cools the sealed part of the packaging bag, it can also further dissipate the heat of the heated sealed part from below.

[0036] In a further preferred embodiment, a water outlet pipe 6 is connected to one side of the water tank 5.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
