Technical Field

[0001] The present application relates to the technical field of packaging machinery, and in particular to a heat sealing head for a sealing machine. Background Art

[0002] A sealing machine is a packaging device that can seal containers filled with packaging materials so that the products can be sealed and preserved. It is widely used in food, medicine, chemical industry, cosmetics and other fields.

[0003] A sealing machine suitable for sealing cosmetic cans in the related technology includes a sealing coil and a heat sealing head. A high-frequency current generates a magnetic field in the sealing coil, causing the heat sealing head to generate an induced current and heat up instantly, causing the can seal to melt, thereby achieving the purpose of sealing.

[0004] However, in actual use, the heat sealing head often has excessive contact with the can to be packaged, causing unnecessary damage to the non-sealed area of ​​the can to be packaged, thereby affecting the packaging quality. Therefore, it is necessary to use specific technical means to improve the design of the sealing machine, especially the heat sealing head, to reduce excessive contact and unnecessary damage and improve the overall quality and efficiency of packaging. Utility Model Content

[0005] In order to solve the problem in the related art that the heat sealing head of the sealing machine is prone to excessive contact with the can body to be packaged, the present application provides a heat sealing head for the sealing machine.

[0006] The present application provides a heat sealing head for a sealing machine using the following technical solutions:

[0007] A heat sealing head of a sealing machine comprises a body and a sealing ring arranged on the body, wherein the diameter of the sealing ring gradually increases from top to bottom, so that the outer side surface of the sealing ring is inclined.

[0008] By adopting the above technical solution: when the heat sealing head contacts the can body to be packaged, the inclined sealing ring can maintain a certain gap with the area not to be packaged to avoid excessive contact.

[0009] Preferably, the outer side surface of the sealing ring is hollowed out.

[0010] By adopting the above technical solution: the hollow design can increase the heat conduction efficiency, making the sealing process more uniform and efficient.

[0011] Preferably, the sealing ring is detachably arranged at the bottom of the body.

[0012] By adopting the above technical solution: the sealing ring can be designed as a detachable structure. When the heat sealing head needs to be replaced due to aging or damage, the sealing ring can be easily disassembled and replaced with a new one without replacing the entire heat sealing head, which is conducive to reducing maintenance costs.

[0013] Preferably, the top of the sealing ring is provided with a metal thread, and the bottom of the body is provided with a thread groove matched with the metal thread.

[0014] By adopting the above technical solution: the sealing ring is rotated so that the metal thread on the top thereof matches with the thread groove at the bottom of the body, thereby achieving fixation of the sealing ring.

[0015] Preferably, a snap ring is provided on the top of the sealing ring, and a snap groove matched with the snap ring is provided on the bottom of the body.

[0016] By adopting the above technical solution: inserting the clamping ring into the clamping groove, rotating the clamping ring to lock it with the clamping groove, and fixing the sealing ring.

[0017] Preferably, a plurality of grooves are provided on the outer side surface of the body.

[0018] By adopting the above technical solution: these grooves not only help to reduce the weight of the heat sealing head, but also increase the contact area between the heat sealing head and the air, thereby improving the heat dissipation efficiency and extending the service life of the heat sealing head.

[0019] Preferably, the groove is semi-cylindrical, and the bottom of the groove is 1-2 cm away from the bottom of the body.

[0020] By adopting the above technical solution: such a design can ensure that the groove will not affect the contact surface between the heat sealing head and the tank body, while effectively improving the heat dissipation efficiency.

[0021] Preferably, the angle formed by the outer side surface of the sealing ring and the vertical direction is 20-30°.

[0022] By adopting the above technical solution: such an inclination angle can not only avoid excessive contact between the heat sealing head and the can body, but also ensure uniform pressure distribution during the sealing process, thereby improving the sealing quality.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The present application effectively avoids the problem of excessive contact between the heat sealing head and the can body to be packaged by designing the outer side of the sealing ring to be inclined and hollowed out. This design enables the heat sealing head to maintain a certain gap with the non-to-be-packaged area when contacting the can body, reducing the risk of damage to the can body. At the same time, the heat conduction efficiency is increased during sealing, making the sealing process more uniform and efficient, and improving the stability of the sealing quality;

[0025] 2. This application significantly reduces maintenance costs by adopting a detachable sealing ring design. When the sealing ring is aged or damaged, it can be easily removed and replaced with a new one without replacing the entire heat sealing head. This design not only simplifies the maintenance process, but also reduces the time and cost required for maintenance;

[0026] 3. The present application effectively improves the heat dissipation efficiency of the heat sealing head by opening a number of semi-cylindrical grooves on the outer surface of the main body. These grooves increase the contact area between the heat sealing head and the air, promote heat dissipation, and thus reduce the risk of damage to the heat sealing head due to overheating.

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] Example 1

[0034] Embodiment 1 of the present application discloses a heat sealing head of a sealing machine, referring to Figure 1 and Figure 2 , comprising a body 1 and a sealing ring 2 installed at the bottom of the body 1, wherein the diameter of the sealing ring 2 gradually increases from top to bottom along the axis, so that the angle formed by the outer side of the sealing ring 2 and the vertical direction is 20°, forming an inclined surface. When the heat sealing head contacts the can body, the sealing ring 2 is in an open umbrella shape, the lower half of which is tightly attached to the area to be packaged, and the upper half can maintain a certain gap with the area not to be packaged, thereby reducing the possibility of excessive contact and facilitating improving the overall quality of the package;

[0035] In addition, the outer side surface of the sealing ring 2 is hollowed out, which effectively increases the heat conduction efficiency and makes the sealing process more uniform and efficient.

[0036] To make the heat seal head easy to maintain, refer to Figure 2The sealing ring 2 can be removed from the main body 1. A metal thread 21 is installed on the top of the sealing ring 2, and a thread groove 11 matched with the metal thread 21 is opened at the bottom of the main body 1. The metal thread 21 on the sealing ring 2 is aligned with the thread groove 11 at the bottom of the main body 1, and the sealing ring 2 is rotated until the sealing ring 2 is tightened on the main body 1 to achieve the fixation of the sealing ring 2. When the heat sealing head needs to be replaced due to aging or damage, the new sealing ring 2 can be easily disassembled and replaced without replacing the entire heat sealing head, which is beneficial to reducing maintenance costs.

[0037] To further enhance the heat dissipation capacity of the heat seal head, refer to Figure 1 and Figure 2 Four semi-cylindrical grooves 13 are evenly arranged on the outer surface of the main body 1, wherein the bottom of the groove 13 is kept at a distance of 1 cm from the bottom of the main body 1, ensuring that the groove 13 does not affect the contact surface between the heat sealing head and the can body, while effectively improving the heat dissipation efficiency. These grooves 13 not only help to reduce the weight of the heat sealing head, but also increase the contact area between the heat sealing head and the air, thereby improving the heat dissipation efficiency and extending the service life of the heat sealing head.

[0038] The working process and implementation principle in Example 1 are as follows:

[0039] When the sealing machine is working, the sealing ring 2 of the heat sealing head is in contact with the can body to be packaged. Since the outer side surface of the sealing ring 2 is inclined and a certain gap is maintained with the non-to-be-packaged area, the problem of excessive contact is avoided. At the same time, the hollow design of the sealing ring 2 ensures uniform heat conduction and efficient sealing. During the sealing process, the groove 13 on the outer side surface of the main body 1 effectively increases the heat dissipation area and improves the heat dissipation efficiency, thereby extending the service life of the heat sealing head. When the heat sealing head needs to be replaced, it is only necessary to unscrew the metal thread 21 on the sealing ring 2 to easily disassemble and replace the new sealing ring 2.

[0040] Example 2

[0041] Embodiment 2 of the present application discloses a heat sealing head of a sealing machine, referring to Figure 3 and Figure 4 The difference from Example 1 is that the connection method between the sealing ring 2 and the main body 1 is different. A clamping ring 22 is installed on the top of the sealing ring 2, and a clamping groove 12 adapted to the clamping ring 22 is installed on the bottom of the main body 1.

[0042] The working process and implementation principle in Example 2 are as follows:

[0043] During installation, it is only necessary to align the snap ring 22 on the sealing ring 2 with the snap groove 12 at the bottom of the body 1, then insert the snap ring 22 into the snap groove 12, and rotate the snap ring 22 to lock it with the snap groove 12, so as to fix the sealing ring 2. Similarly, when it needs to be removed, it is only necessary to rotate the sealing ring 2 to disengage the snap ring 22 on the sealing ring 2 from the fixation of the snap groove 12.

[0044] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
