Technical Field

[0001] The utility model relates to the technical field of vacuum packaging machines, in particular to a vacuum packaging machine with a self-cleaning mechanism. Background Art

[0002] Vacuum packaging has many advantages such as extending the shelf life, and various vacuum packaging machines have been widely used. When users want to use a vacuum packaging machine to package food, they need to pre-fix the plastic bag containing the food on the card strip of the heat sealer, and then let the vacuum pump extract the air in the vacuum chamber through the pipeline to form negative pressure, and finally control the heat sealer to seal.

[0003] In the above packaging process, when some items contain a certain amount of powder or liquid, they are easily sucked into the pipe. Although existing vacuum packaging machines are equipped with filters, some of these powders or liquids still remain in the suction holes or adhere to the pipe wall. If they are not processed for a long time, they will rot and affect food hygiene. Therefore, these equipment need to be cleaned regularly.

[0004] The existing vacuum packaging machine needs to be completely dismantled and then taken out for cleaning. Not only is the disassembly and assembly process cumbersome, but the air pipe is long and it is difficult to clean the pipe wall thoroughly, resulting in poor cleaning effect. Utility Model Content

[0005] Based on the above description, the utility model provides a vacuum packaging machine with a self-cleaning mechanism to solve the shortcomings of existing vacuum packaging machines, such as the need to disassemble the equipment during regular cleaning, cumbersome maintenance, and relatively general cleaning effect.

[0024] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0026] Combination Figure 1-4 As shown, a vacuum packaging machine with a self-cleaning mechanism comprises:

[0027] The body 1 is the outer shell of the entire device, used to protect and support other components;

[0028] The vacuum chamber 2 is a rectangular frame with an opening at the top, which is arranged on the top of the fuselage 1 and is detachably mounted on the fuselage 1. A heat-sealing card strip 21 and a hole 22 are arranged on the inner bottom surface of the vacuum chamber 2.

[0029] The vacuum chamber 3 is arranged at the bottom of the vacuum chamber 2 and is in a bucket shape. A filter 31 is provided inside the vacuum chamber 2 and all the holes 22 on the vacuum chamber 2 are interconnected.

[0030] The exhaust pipe 4 is arranged at the bottom of the vacuum chamber 3, and its bottom end is connected to the vacuum pump 6 for evacuating the vacuum chamber 2 to form a negative pressure inside the vacuum chamber 2, thereby cooperating with the heat-sealed card strip 21 for rapid packaging.

[0031] The cleaning assembly 5 is arranged inside the fuselage 1 and close to the bottom side of the exhaust pipe 4, and is used for automatically cleaning the inner wall of the exhaust pipe 4, so that it can be completed without disassembly, thereby simplifying its cleaning arrangement.

[0032] Specifically, the heat-sealing card strip 21 is arranged longitudinally, so before vacuum packaging, the mouth of the packaging bag containing the food needs to be pre-stuck inside the heat-sealing card strip 21 so that after the subsequent vacuuming is completed, the heat-sealing card strip 21 is heated to complete the packaging.

[0033] Moreover, a slide groove 32 is provided on the inner wall of the top of the fuselage 1, and a protrusion is correspondingly provided on the outer wall of the vacuum chamber 2 and is slidably inserted into the slide groove 32. The two are movably assembled, and a plurality of bolt holes are respectively provided on the four sides of the top surface of the fuselage 1 and the vacuum chamber 2. The two are fixed by bolts. This structure is a detachable fixed connection. Therefore, when the internal parts need to be replaced or thoroughly cleaned later, they can be quickly disassembled and assembled by bolts.

[0034] A limiting groove is provided on the bucket-shaped side wall of the vacuum chamber 3, and the slide groove 32 extends outward along one side thereof to the outside of the fuselage 1, and a square hole 11 is formed on the outer wall of the fuselage 1, which is connected to the interior of the vacuum chamber 3. A sealing block 33 is provided in the square hole 11, and an insert plate 34 is provided on the inward end surface of the sealing block 33. A filter 31 is installed on the insert plate 34 by bolts and clamping. The insert plate 34 is inserted into the limiting groove so that the filter 31 can completely cover the channel at the bottom of the vacuum chamber 3. Therefore, in actual use, the filter 31 can be cleaned regularly to ensure the cleanliness of the interior of the vacuum packaging machine and prevent powdered or liquid food from entering the pipeline and causing blockage.

[0035] In addition, it is necessary to ensure that the structure is a sealed connection, so a fixing groove should be arranged on the periphery of the square hole 11, and a flange should be set around the sealing block 33. When the sealing block 33 is fully inserted into the square hole 11, the flange fits with the bottom surface of the fixing groove, and the two are fixed by an annular groove sealing structure and reinforced by bolts at the four corners. At the same time, in order to facilitate its removal, a handle should be set at the center of the outward end face of the sealing block 33.

[0036] The filter 31 should be an activated carbon filter cartridge. The activated carbon can be repeatedly used by being exposed to the sun, which can effectively reduce the cost of use.

[0037] The cleaning assembly 5 includes a first three-way joint 51 , a second three-way joint 52 , a water inlet pipe 53 connected to the first three-way joint 51 , a water outlet pipe 54 connected to the second three-way joint 52 , and an ultrasonic cleaning device arranged at the bottom of the second three-way joint 52 .

[0038] Among them, the exhaust pipe 4 is arranged in an L shape as a whole, and the first three-way joint 51 and the second three-way joint 52 are respectively arranged at the two ends of the vertical section of the exhaust pipe 4. The first three-way joint 51 is arranged as an electric three-way valve, which can control the connection and disconnection of the water inlet pipe 53 and the exhaust pipe 4. The second three-way joint 52 is an ordinary three-way pipe structure, and electronic valves 55 are respectively arranged at both ends thereof. The two electronic valves 55 are independently controlled, and one of them is connected to the water outlet pipe 54 for controlling the discharge of cleaning water. A water pump is provided on the water inlet pipe 53, and it is connected to an external water storage tank. The water outlet pipe 54 is directly connected to the recovery tank for centralized filtration and recovery.

[0039] The ultrasonic cleaning device consists of two parts: an ultrasonic generator 57 and an ultrasonic vibration rod 56. A mounting base is provided at the bottom end of the ultrasonic vibration rod 56, and the mounting base is tightly fitted at the bottom center of the second three-way joint 52. The ultrasonic vibration rod 56 extends upward and passes through the second three-way joint 52 and extends to the interior of its exhaust pipe 4. The ultrasonic generator 57 is arranged close to one side and is electrically connected to the ultrasonic vibration rod 56.

[0040] At the same time, a threaded hole 58 should be provided at the center of the bottom surface of the second three-way joint 52, and the top surface of the mounting seat should protrude upward and a threaded section should be provided on the side wall for movable assembly. On the basis of this connection, the transmission effect of the ultrasonic wave and the sealing between the two should be taken into consideration. Therefore, an elastic part with a shock-absorbing effect should be provided at the connection between the mounting seat and the ultrasonic vibration rod 56, such as a spring, a rubber pad or other flexible object, which can not only reduce the impact of vibration on the pipeline body, but also have a certain sealing effect to prevent water leakage.

[0041] Combining all the above structures, a PLC microcontroller should be used to connect them and then program them so that the staff can automate them with one click, further improving the convenience of operation.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solution recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solution from the technical solution of the embodiments of the utility model.
