[0052] Please refer to Figures 1-6 , the present utility model provides a technical solution: a vacuum packaging machine for corn, including a vacuum packaging machine main body 1. The vacuum packaging machine main body 1 adopts the same principle as the comparative document CN220563032U and is a direct application of the prior art, so it will not be described in detail herein;

[0053] A protective outer cover 2, which is detachably and fixedly assembled on the upper end of the vacuum packaging machine main body 1. Moreover, the upper end part and the feeding end of the vacuum packaging machine main body 1 are located outside the protective outer cover 2, and the electronic device part and the feeding end of the vacuum packaging machine main body 1 are located outside the protective outer cover 2, ensuring normal feeding and avoiding the influence of atomized sprayed disinfectant and disinfectant vapor on the electronic devices;

[0054] An operation window 3 is provided corresponding to the feeding end of the vacuum packaging machine main body 1 and the vacuum thermocompression sealing component. Through the operation window 3, vacuum thermocompression sealing operations are performed on the conveyed packaging bags filled with corn.

[0055] A discharge window 5 is opened on the outer wall of the protective cover 2 near the discharge end of the vacuum packaging machine main body 1 for discharging the packaging bags filled with corn after vacuum thermocompression sealing.

[0056] There are two disinfectant spray pipes 6, and the two disinfectant spray pipes 6 are respectively fixedly assembled on the left and right sides of the upper surface of the protective cover 2.

[0057] The output ends of the disinfectant spray pipes 6 extend into the interior of the protective cover 2. The distribution method on both sides of the disinfectant spray pipes 6 ensures that the atomized disinfectant spraying area is wide enough to ensure the disinfection effect.

[0058] A one-way exhaust valve 7 is uniformly and fixedly connected to the middle of the upper surface of the protective cover 2.

[0059] An electric heating wire 8 is wound around the inner wall of the protective cover 2, and the electric heating wire 8 is electrically connected to an external switch. The external switch controls the opening or closing of the electric heating wire 8. When the electric heating wire 8 is turned on, the sprayed atomized disinfectant is heated, and the atomized disinfectant evaporates into disinfectant vapor to disinfect the components of the vacuum packaging machine main body more evenly. The disinfectant vapor finally discharges from the one-way exhaust valve, and areas that are not easily disinfected can also be disinfected, improving the disinfection effect.

[0060] In some embodiments, in order to conveniently block the discharge window 5 while not affecting the discharge, the discharge window 5 includes:

[0061] A second window main body 51 is opened on the outer wall of the protective cover 2 below the discharge end of the vacuum packaging machine main body 1.

[0062] Silicone tapes 52 are uniformly pasted and fixed on the top surface of the inner wall of the second window main body 51, and the lower ends of the silicone tapes 52 abut against the upper surface of the vacuum packaging machine main body 1.

[0063] The edges of adjacent silicone tapes 52 are in contact with each other, and the edges of the silicone tapes 52 on both sides are in contact with the same side of the inner wall of the second window main body 51. The contact and occlusion of adjacent silicone tapes 52 reduce the overflow amount of the atomized disinfectant and the disinfectant vapor.

[0064] In some embodiments, in order to uniformly spray the atomized disinfectant into the protective cover to better disinfect and sterilize the non-electronic components on the vacuum packaging machine main body, the disinfectant spray pipe 6 includes:

[0065] A liquid discharge pipe 61 with both ends sealed.

[0066] There are eight drain pipes 61 arranged in parallel along the width direction of the protective outer cover 2;

[0067] The bottom surface of the drain pipe 61 is uniformly and fixedly connected with a first atomizing nozzle 62, and the first atomizing nozzle 62 is the output end of the disinfectant spraying pipeline 6;

[0068] A connecting pipe is fixedly connected at the position between adjacent drain pipes 61. The drain pipe 61 close to the end of the protective outer cover 2 is fixedly connected with a liquid inlet pipe 63. Disinfectant is introduced under high pressure at the liquid inlet pipe 63. The disinfectant enters each drain pipe 61 through the connecting pipe and is finally atomized and sprayed out from the first atomizing nozzle 62 on the bottom surface of the drain pipe 61.

[0069] In some embodiments, in order to facilitate exposing the front opening of the protective outer cover 2 and facilitating the maintenance of the blocked part of the vacuum packaging machine main body 1, the front opening of the protective outer cover 2 is designed, and a maintenance-friendly structure 4 is assembled at the front opening of the protective outer cover 2, which includes:

[0070] There are two clamping frames 41, and the two clamping frames 41 are respectively fixedly assembled on the left and right sides of the lower edge of the front opening of the protective outer cover 2;

[0071] A baffle 42 blocks the front opening of the protective outer cover 2, and the lower end of the baffle 42 is inserted into the two clamping frames 41 on both sides;

[0072] A handle block 43 is fixedly assembled at the upper end of the baffle 42. During use, grasp the handle block 43 and pull out the baffle 42 from the upper end to expose the front opening of the protective outer cover 2.

[0073] In some embodiments, in order to more conveniently grasp and pull out the baffle, when in use, fingers are inserted into the circular through hole on the handle block 43 to increase the comfort of grasping. A circular through hole is opened on the handle block 43, and the circular through hole makes the handle block 43 into a ring-shaped handle.

[0074] In some embodiments, in order to better cover the middle position of the inner cavity of the protective outer cover 2 during atomizing spraying disinfection, a middle disinfectant spraying pipe group 12 is fixedly connected to the side of the disinfectant spraying pipeline 6 far from the end of the protective outer cover 2;

[0075] The middle disinfectant spraying pipe group 12 is composed of four disinfectant spraying pipes, and the disinfectant spraying pipes of the middle disinfectant spraying pipe groups 12 on both sides are uniformly laid on the middle of the upper surface of the protective outer cover 2;

[0076] The output end of the disinfectant spraying pipe extends into the protective outer cover 2.

[0077] In some embodiments, in order to perform atomizing spraying disinfection on the middle of the inner cavity of the protective outer cover 2 and make the atomizing spraying disinfection coverage more uniform, the disinfectant spraying pipe includes:

[0078] The branch pipe 121 has one end sealed, and the other end of the branch pipe 121 is fixedly communicated with one side of the disinfection liquid spraying pipe 6 away from the end of the protective cover 2;

[0079] The bottom surface of the branch pipe 121 is fixedly communicated with the second atomizing nozzles 122 evenly, and the second atomizing nozzles 122 are the output ends of the disinfection liquid spraying pipes. The disinfection liquid is fed into the branch pipe 121 along one side of the disinfection liquid spraying pipe 6 away from the end of the protective cover 2, and finally atomizes and sprays out from the second atomizing nozzles 122.

[0080] In some embodiments, for the convenience of installation and disassembly of the protective cover 2, the protective cover 2 includes:

[0081] The cover body 21, the upper part and the feeding end of the vacuum packaging machine main body 1 are located outside the cover body 21;

[0082] Connecting ear plates 22 are fixedly assembled at the front and rear edges of the bottom surface of the cover body 21, and the connecting ear plates 22 are fixedly connected to the outer wall of the same side of the vacuum packaging machine main body 1 through bolts.

[0083] In some embodiments, for the stable support of the device, support legs 10 are fixedly assembled evenly at the bottom surface edge of the vacuum packaging machine main body 1, and cross beams 11 are fixedly connected at the positions between adjacent support legs 10.

[0084] In some embodiments, for the diversion and discharging of the vacuum-packed corn output by the vacuum packaging machine main body 1, one end of a diversion plate 9 is fixedly assembled inside the support leg 10 close to the output end of the vacuum packaging machine main body 1, and the other end of the diversion plate 9 extends obliquely downward to the outside of the support leg 10, making it more convenient to collect the vacuum-packed corn after diversion and discharging.

[0085] Working principle:

[0086] The electronic device part and the feeding end of the vacuum packaging machine main body 1 are located outside the protective cover 2, ensuring normal feeding and avoiding the influence of atomized sprayed disinfection liquid and disinfection liquid vapor on the electronic devices. The protective cover 2 can also protect the devices of the vacuum packaging machine main body 1 located therein, and the protective cover 2 plays a role in shielding dust;

[0087] When it is necessary to disinfect the devices of the vacuum packaging machine main body 1, high-pressure disinfectant is introduced into the liquid inlet pipe 63 of the disinfection liquid spraying pipe 6. The disinfectant enters each drain pipe 61 through the connecting pipe, and finally atomizes and sprays out from the first atomizing nozzles 62 at the bottom surface of the drain pipe 61. The distribution method on both sides of the disinfection liquid spraying pipe 6 ensures that the atomized disinfection liquid spraying surface is wide enough to ensure the disinfection effect;

[0088] The heating wire 8 is controlled to be turned on or off by an external switch. When the heating wire 8 is turned on, it heats the atomized disinfectant liquid for spraying. The atomized disinfectant liquid evaporates into disinfectant vapor to disinfect the components of the vacuum packaging machine main body more evenly. Finally, the disinfectant vapor is discharged from the one-way exhaust valve, enabling disinfection of areas that are not easily disinfected and improving the disinfection effect.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
