Description

Technical Field

[0001] This utility model relates to the field of vacuum machine technology, and in particular to a sealing heating component for a vacuum machine. Background Technology

[0002] A vacuum sealer is a device used to seal food, medicine, and other items. It works by removing air from the packaging, creating a low-oxygen environment that helps extend the shelf life of the goods and prevents oxidation and bacterial growth. Vacuum sealers are frequently used in homes, restaurants, and the food processing industry to maintain food freshness and extend its shelf life.

[0003] To improve heat conduction efficiency and quickly dissipate heat from the heating element, existing vacuum sealing machines incorporate aluminum strips into the heating element. However, these aluminum strips expand during heating, which can cause deformation or displacement of other components in the heating element. This can lead to structural deformation or damage to parts of the heating element, increasing the maintenance frequency of the vacuum sealing machine and making it difficult to accurately control the temperature of the heating wire using temperature sensors.

[0030] Reference Figure 1-9 As shown, a sealing heating assembly for a vacuum machine includes: a main body 1 and a cover 2 disposed on the main body 1.

[0031] The main body 1 is provided with a mounting plate 11, which forms a mounting groove 111, and a heating component 3 is disposed on the mounting plate 11 and the mounting groove 111. The heating component 3 includes: a high-temperature tape 31, a heating wire 32, a support member 33, and a heating wire terminal 34. The support member 33 is disposed on the mounting groove 111, and the upper end of the support member 33 is provided with the heating wire 32. The high-temperature tape 31 is disposed on the first surface of the mounting plate 11, and the heating wire terminal 34 is disposed on the second surface of the mounting plate 11. The first end of the heating wire terminal 34 is connected to the heating wire 32, and its second end is electrically connected to the controller. By optimizing the structure of the mounting plate and using a temperature sensor, the heat generated by the heating wire 32 is evenly conducted to the entire heating area by setting the support member 33, thus avoiding the structural deformation problem caused by the expansion of aluminum strips in traditional vacuum sealing machines.

[0032] Furthermore, to ensure the heating component 3 is stably connected to the main body 1, a mounting plate 11 is provided on the main body 1. The mounting plate 11 has a first surface and a second surface. A mounting groove 111 is formed on the first surface of the mounting plate 11, and a support member 33 is provided in the mounting groove 111. The mounting groove 111 is used to stably connect the heating component 3 to the main body 1. Both ends of the mounting groove 111 are provided with bosses 1112, and the bosses 1112 are recessed with slots for holding the heating wire 32. The mounting plate 11 is provided with insertion holes 1113 near the bosses 1112, and the heating wire 32 is disposed on the support member. The upper end of the heating wire 32 is inserted into the mounting plate 11 through the insertion hole 1113, so that both ends of the heating wire 32 are bent to the second surface of the mounting plate 11. Multiple heat dissipation holes 1111 are provided on the mounting groove 111 to dissipate the heat generated by the heating wire 32. The mounting plate 11 is provided with through holes 112 near both ends of the mounting groove 111. The through holes 112 are used to connect and fix the high temperature tape 31. The high temperature tape 31 is used to facilitate the uniform conduction of the heat generated by the heating wire 32 to the vacuum bag and to protect other components on the vacuum sealing machine from direct contact with the heating wire 32.

[0033] Furthermore, the mounting plate 11 has a plurality of retaining plates 115 on its second surface. The retaining plates 115 are used to connect the temperature sensor 36 and the fuse 37. The mounting plate 11 has a limiting plate 114 on its second surface near the insertion hole 1113. The limiting plate 114 is used to fix the heating wire terminal 34 to prevent the heating wire terminal 34 from shifting during use and affecting the position of the heating wire 32. A connecting post 113 is provided near the limiting plate 114. The connecting post 113 is used to connect the heating wire terminal 34 and fix the heating wire terminal by bolts or crimping. The mounting plate 11 also has a groove 116 on the side away from the mounting groove 111. The groove 116 is used to place the controller or sensor module.

[0034] Furthermore, the heating assembly 3 includes: a high-temperature tape 31, a heating wire 32, a support member 33, and a heating wire terminal 34. The upper end of the support member 33 is provided with the heating wire 32. A mica sheet is also provided between the support member 33 and the heating wire 32. The mica sheet has good insulation properties and high-temperature resistance, and can maintain stable performance in high-temperature environments, preventing current leakage or heat conduction from damaging the body, and to a certain extent protecting the electronic components inside the body. The high-temperature tape 31 is provided on the first surface of the mounting plate 11, and the heating wire terminal 34 is provided on the second surface of the mounting plate 11. The first end of the heating wire terminal 34 is connected to the heating wire 32, and its second end is connected to the controller. The first end of the heating wire terminal 34 is provided with a first bending section 341, and its second end is provided with a second bending section 342. By providing the first bending section 341, the heating wire 32 can be more firmly fixed, preventing the heating wire 32 from loosening or shifting due to vibration or thermal expansion during heating. By providing the second bending section 342, the heating wire 32 can be more firmly fixed, preventing the heating wire 32 from loosening or shifting due to vibration or thermal expansion during heating. To facilitate the connection between the heating wire terminal 34 and the controller, and to keep the connected wiring away from the heating wire 32 to avoid high temperature affecting the wiring connection, the heating wire terminal 34 has a groove 344 near the first bend 341 for holding the heating wire 32. The groove 344 is used to hold the heating wire 32. The heating wire terminal 34 has a hook part 343 on the side away from the first bend 341. A spring 35 is connected between the heating wire terminal 34 and the heating wire 32. The first end of the spring 35 is connected to the heating wire 32, and its second end is connected to the heating wire 32. The end is connected to the hook part 343. The spring 35 is used to straighten the heating wire 32 and provide elastic compensation. During the heating process, the heating wire 32 will stretch due to thermal expansion and contract after cooling. The spring 35 can effectively relieve this mechanical stress and prevent the heating wire 32 from being damaged. The heating wire terminal 34 is provided with a connection hole 345 near the hook part 343. The connection hole 345 is used to connect the connecting post 113. The second bent section 342 is provided with a through hole 346, which is used for circuit connection.

[0035] Furthermore, the heating assembly 3 also includes a temperature sensor 36 and a fuse 37. Both the temperature sensor 36 and the fuse 37 are disposed on the second surface of the mounting plate 11 and are secured to the mounting plate 115. The temperature sensor 36 is connected to the fuse 37, and the other end of the temperature sensor 36 is connected to the controller. The other end of the fuse 37 is connected to the through hole 346 of the heating wire terminal 34. The controller, in cooperation with the temperature sensor 36, is used to control and adjust the heat generated by the heating wire 32 to ensure the stability and uniformity of the heating temperature, and to protect the mounting plate 11 from melting due to excessive heat in the heating wire 32. The fuse 37 is used to protect the circuit and prevent damage to the vacuum sealing machine caused by overheating.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
