[0005] The box body forms two vacuum chambers arranged horizontally and spaced apart;

[0006] A cover body, slidably connected to the box body, wherein a sliding direction of the cover body relative to the box body is parallel to an arrangement direction of the vacuum chambers so that the cover body can alternately cover the vacuum chambers during a sliding process relative to the box body;

[0007] Permanent magnets are arranged at the front and rear ends of the cover body along the moving direction of the cover body;

[0008] An electromagnetic assembly, comprising a first electromagnetic device mounted on the box body and an electric control element electrically connected to the first electromagnetic device and used to make the first electromagnetic device generate magnetism, wherein the first electromagnetic device is arranged on both sides of the cover body along the moving direction of the cover body and respectively corresponds to the permanent magnets located at the head and tail ends of the cover body;

[0009] A sensor is communicatively connected to the electric control element and is used to detect a material filling signal of the vacuum chamber.

[0010] Optionally, the length of the cover body in its sliding direction is equal to half of the distance between the first electromagnetic components on both sides.

[0011] Optionally, a spring sheet for abutting against the permanent magnet is formed on the box body;

[0012] The deformation direction of the elastic sheet is adapted to the moving direction of the cover body so that the cover body and the box body tend to separate from each other after the permanent magnet and the first electromagnetic device are attracted and abutted.

[0013] Optionally, a receiving cavity for receiving the spring piece is formed on the box body, and the spring piece can be completely received in the receiving cavity.

[0014] Optionally, a step is formed on the box body, and intersecting surfaces of the box body used to form the step are both slidably abutted against the cover body.

[0020] Furthermore, the inner cover is slidably connected to the cover body through a plurality of guide rods and a spring is provided on the guide rod. When the magnetic attraction of the second electromagnetic device disappears, the spring has a tendency to cause the inner cover to rise away from the vacuum chamber mouth surface; a sealing strip adapted to the vacuum chamber mouth surface is installed on the inner cover, and the guide rod is located outside the sealing strip area.

[0021] The beneficial effect of the automatic cover-shifting double-chamber vacuum packaging machine provided by the present application is that: compared with the prior art, in the automatic cover-shifting double-chamber vacuum packaging machine provided by the present application, the cover body is slidably connected to the box body and is respectively connected to permanent magnets at the head and tail ends in the sliding direction. When the sensor detects the material filling signal in the vacuum chamber, it can be fed back to the electric control element in the electromagnetic component and the corresponding first electromagnetic device can be controlled by the electric control component to generate magnetism opposite to the permanent magnet and attract the cover body. In this way, the cover body can quickly and alternately close the two vacuum chambers by controlling the first electromagnetic devices on both sides to generate attractive forces on the permanent magnets respectively.

[0032] Please also read Figures 1 to 4 Now, an automatic cover-transferring double-chamber vacuum packaging machine provided in an embodiment of the present application is described. The automatic cover-transferring double-chamber vacuum packaging machine comprises a box body 101, a cover body 103, a permanent magnet 104, an electromagnetic component and a sensor 107. Among them:

[0033] The box body 101 forms two vacuum chambers 102 arranged horizontally and spaced apart. The cover body 103 is slidably connected to the box body 101 and the sliding direction of the cover body 103 relative to the box body 101 is parallel to the arrangement direction of the vacuum chambers 102 so that the cover body 103 can alternately cover the vacuum chambers 102 during the sliding process relative to the box body 101. The permanent magnet 104 is arranged at the head and tail ends of the cover body 103 along the moving direction of the cover body 103. The electromagnetic assembly includes a first electromagnetic device 105 installed on the box body 101 and an electric control element 106 electrically connected to the first electromagnetic device 105 and used to make the first electromagnetic device 105 generate magnetism. The first electromagnetic device 105 is arranged on both sides of the cover body 103 along the moving direction of the cover body 103 and corresponds to the permanent magnets 104 located at the head and tail ends of the cover body 103 respectively. The sensor 107 is communicatively connected to the electric control element 106 and used to detect the material filling signal of the vacuum chamber 102. Here, the first electromagnetic device 105 is an electromagnet.

[0034] As a preferred embodiment, the automatic cover-moving double-chamber vacuum packaging machine also includes an inner cover 1031 arranged in the cover body 103 and capable of being away from or abutting against the mouth surface of the sealed vacuum chamber 102, and a second electromagnetic device 115 arranged on the box body 101, located on the outside of the corresponding vacuum chamber 102 and on the inside of the outer edge of the inner cover 1031. When the inner cover 1031 is located above the vacuum chamber 102, the second electromagnetic device 115 is used to magnetically attract the inner cover 1031 to abut against the mouth surface of the vacuum chamber 102.

[0035] Further preferably, the inner cover 1031 is slidably connected to the cover body 103 through a plurality of guide rods 1033, and a spring 1034 is provided on the guide rod 1033. When the magnetic attraction of the second electromagnetic device 115 disappears, the spring 1034 has a tendency to make the inner cover 1031 rise away from the mouth surface of the vacuum chamber 102; a sealing strip 1035 adapted to the mouth surface of the vacuum chamber 102 is installed on the inner cover 1031, and the guide rod 1033 is located outside the area of ​​the sealing strip 1035. The sealing strip 1035 seals the mouth surface of the vacuum chamber 102 when the inner cover 1031 is covered on the vacuum chamber 102, so as to ensure that the vacuum chamber 102 can reach a set vacuum degree when evacuating. The guide rod 1033 is located outside the area of ​​the sealing strip 1035, which is conducive to ensuring the sealing effect of the sealing strip 1035; see especially Figure 2 and Figure 4Usually, cavities 1036 with openings toward the vacuum chamber 102 are provided at the four corners of the inner cover 1031, and the guide rods 1033 are slidably installed in the corresponding cavities 1036 one by one, and the upper ends pass through the bottom of the cavities 1036 and abut against the cover 103, and the guide rods 1033 are tightened and fixed on the cover 103 by bolts 1032, wherein the lower end of the guide rod 1033 located in the cavity 1036 has a flange, and the spring 1034 is sleeved on the guide rod 1033 and the two ends are respectively abutted against the flange and the cavity 1036, so that the spring 1034 has a tendency to make the inner cover 1031 rise, and at the same time, the guide rod 1033 guides the movement of the inner cover 1031, here, the first electromagnetic device 105 and the second electromagnetic device 115 are both electromagnets.

[0036] According to the above structure provided in the present embodiment, in the automatic cover-transferring double-chamber vacuum packaging machine provided in the present embodiment, the cover body 103 is slidably connected to the box body 101 and is respectively connected to permanent magnets 104 at both ends of the sliding direction. When the sensor 107 detects the material filling signal in the vacuum chamber 102, it can be fed back to the electric control element 106 in the electromagnetic component and the electric control component can be used to control the corresponding first electromagnetic device 105 to generate magnetism opposite to the permanent magnet 104 and attract the cover body 103. In this way, the first electromagnetic devices 105 on both sides can be controlled to respectively generate attraction to the permanent magnet 104. The cover 103 is forced to quickly and alternately close the two vacuum chambers 102. At the same time, during operation, when the cover 103 reaches the corresponding vacuum chamber 102, the second electromagnetic device 115 generates a magnetic attraction to suck the inner cover 1031 to the mouth of the vacuum chamber 102 for sealing, and then evacuates. After completion, the second electromagnetic device 115 stops working and the magnetic attraction disappears. The inner cover 1031 automatically rises and resets, so that the cover 103 can be smoothly transferred to another vacuum chamber 102 position. The high degree of automation is conducive to significantly improving the working efficiency of the automatic cover transfer double-chamber vacuum packaging machine in this embodiment, which is far superior to the prior art. It can be understood that in order to be able to close the cover more quickly, the first electromagnetic devices 105 on both sides can also be used to generate opposite polarities so that a thrust is generated between the first electromagnetic device 105 on one side and the cover 103, and the first electromagnetic device 105 on the other side generates an attraction force, which is conducive to further improving the closing efficiency.

[0037] It can be understood that the component for providing negative pressure to the vacuum chamber 102 can adopt the technology of existing vacuum packaging machines.

[0038] In another embodiment of the present application, please refer to Figures 1 to 4, the length of the cover 103 in its sliding direction is equal to half of the distance between the first electromagnetic devices 105 on both sides. According to the above structure provided in this embodiment, the cover 103 is set to the above size, which is conducive to entering the force range of the first electromagnetic device 105 on the other side when the first electromagnetic device 105 on one side drives the cover 103 to move half the distance between the first electromagnetic devices 105, and can provide a more stable driving force for the movement of the cover 103, which is conducive to further improving the working efficiency of the automatic cover-moving double-chamber vacuum packaging machine in this embodiment.

According to the above structure provided in this embodiment, when the cover body 103 needs to be separated from the first electromagnetic device 105 on one side, the spring piece 108 can provide an initial driving force for the separation of the cover body 103 and the first electromagnetic device 105, which is conducive to faster separation of the cover body 103 and the first electromagnetic device 105, and is conducive to further improving the working efficiency of the automatic cover-transferring double-chamber vacuum packaging machine in this embodiment.

[0041] In another embodiment of the present application, please refer to Figures 1 to 4 , a step 110 is formed on the box body 101, and the intersecting surfaces of the box body 101 used to form the step 110 are all slidably abutted against the cover body 103. According to the above structure provided in this embodiment, the step 110 provided on the box body 101 can provide a more stable sliding guide for the cover body 103, which is not only conducive to improving the stability of the cover body 103 during the movement, but also conducive to further improving the sealing performance between the cover body 103 and the box body 101.
