Description

Technical Field

[0001] This utility model relates to the field of vacuum packaging machine technology, and in particular to an anti-clogging device for vacuum packaging machines. Background Technology

[0002] Currently, vacuum packaging is a common process in packaging manufacturing. Vacuum packaging machines automatically remove air from the bags, achieving a predetermined vacuum level before sealing. Alternatively, nitrogen or other mixed gases can be added before sealing. Vacuum packaging machines are frequently used in the food industry because vacuum packaging helps prevent oxidation, thus achieving long-term preservation.

[0003] In the existing vacuum packaging machine processing, it is necessary to use the air extraction device in the vacuum packaging machine to extract air from the packaging bag to form a vacuum. This is mainly done by using an air extraction pipe to extract air from the packaging bag, and then vacuum sealing is performed.

[0004] The aforementioned air extraction pipe lacks an anti-clogging mechanism and cannot filter the air, which can easily lead to the air being drawn in carrying impurities and clogging the pipe, preventing the formation of a vacuum environment. Therefore, we propose an anti-clogging device for vacuum packaging machines. Utility Model Content

[0005] The purpose of this invention is to provide an anti-clogging device for a vacuum packaging machine. By setting an anti-clogging mechanism, the air is filtered by the cooperation of the connecting cover assembly and the filter assembly, preventing impurities from entering the suction pipe and causing blockage, which would affect the vacuuming effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vacuum packaging machine anti-clogging device, comprising a vacuum packaging machine body, an outer cover disposed on the top of the vacuum packaging machine body, and an air extraction pipe connected to the vacuum packaging machine body, wherein an anti-clogging mechanism is provided at the end of the air extraction pipe, the anti-clogging mechanism comprising:

[0007] A fixing sleeve is fixedly connected to the end of the air extraction pipe;

[0008] A connecting cover assembly is threaded onto the outer surface of the fixing sleeve;

[0009] The outer side of the connecting cover assembly has multiple through slots for air circulation.

[0010] A filter assembly is connected to the outside of the channel, and the filter assembly is used to filter air.

[0011] Preferably, the connecting cover assembly includes a connecting sleeve that is threaded to the outside of the fixed sleeve and a conical cover that is fixedly connected to one end of the connecting sleeve, and a plurality of through slots are formed on the outer surface of the conical cover.

[0012] Preferably, the filtering component includes:

[0013] An arc-shaped piece, the arc-shaped piece being located on the side of the through groove;

[0014] A filter screen is fixedly connected to the middle of the arc-shaped plate, and the filter screen is used to filter air.

[0015] A tab is fixedly connected to one end of the arc-shaped piece near the connecting sleeve.

[0016] Preferably, the arcuate profile of the arcuate piece changes with the arcuate profile of the conical cover, and the planar projection profile of the arcuate piece is trapezoidal.

[0017] Preferably, a snap-fit ​​component is provided between the filter component and the through groove, the snap-fit ​​component being used to connect the filter component and the through groove.

[0018] Preferably, the snap-fit ​​assembly includes:

[0019] The outer frame is fixedly connected to the side of the through groove;

[0020] The outer frame is provided with a locking block around its outer perimeter;

[0021] The card slot is provided on one side of the arc-shaped piece, and a guide groove is provided on one side of the card slot.

[0022] The technical effects and advantages of this utility model are as follows:

[0023] By incorporating an anti-clogging mechanism, the connecting cover assembly and filter assembly work together to filter the extracted air, preventing impurities from entering the suction pipe and causing blockage, which would affect the vacuuming effect. The filter assembly is connected to the connecting cover assembly, and then the connecting cover assembly is screwed onto the fixing sleeve. This anti-clogging mechanism filters the air drawn through the suction pipe, preventing a large amount of impurities from entering and causing blockage, thus affecting the vacuuming effect. Furthermore, the multiple filter components are individual filters, allowing for individual disassembly and assembly later, facilitating cleaning or replacement. This prevents damaged filter components from failing to maintain their anti-clogging effect or from becoming clogged with impurities, thus ensuring effective vacuuming. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] This utility model provides, for example Figure 1-4 The image shows an anti-clogging device for a vacuum packaging machine. Example

[0031] The device includes a vacuum packaging machine body 1, an outer cover 2 located on top of the vacuum packaging machine body 1, and an air extraction pipe 3 connected to the vacuum packaging machine body 1. The end of the air extraction pipe 3 is equipped with an anti-clogging mechanism, which includes: a fixing sleeve 4, which is fixedly connected to the end of the air extraction pipe 3; a connecting cover assembly 5, which is threaded onto the outer surface of the fixing sleeve 4; a through groove 6, which has multiple through grooves 6 on its outer side for air circulation; and a filter assembly 7, which is connected to the outer side of the through grooves 6 for filtering the air. By connecting the filter assembly 7 to the connecting cover assembly 5 and then screwing the connecting cover assembly 5 to the fixing sleeve 4, the anti-clogging mechanism filters the air extracted by the air extraction pipe 3, preventing the extracted air from carrying a large amount of impurities into the air extraction pipe 3, causing blockage and affecting the vacuuming effect. Furthermore, the filter assembly 7 can be replaced separately later, preventing damaged filter assembly 7 from failing to maintain a good anti-clogging effect or from being blocked by impurities, thus affecting the vacuuming effect.

[0032] It should be further explained that the connecting cover assembly 5 includes a connecting sleeve 501 that is threaded to the outside of the fixing sleeve 4 and a conical cover 502 that is fixedly connected to one end of the connecting sleeve 501, and multiple through slots 6 are opened on the outer surface of the conical cover 502; by setting the conical cover 502 to be conical, the filter assembly 7 has a larger filtration space compared to a single sheet filter structure, and also has a larger air flow space, which facilitates the vacuuming operation.

[0033] Furthermore, the filter assembly 7 includes: an arc-shaped plate 701 located on the side of the through groove 6; a filter screen 702 fixedly connected to the middle of the arc-shaped plate 701 and used to filter air; and a protrusion 703 fixedly connected to one end of the arc-shaped plate 701 near the connecting sleeve 501. The arc-shaped plate 701 is connected to the connecting cover assembly 5, and the filter screen 702 is used to filter the air to prevent air carrying impurities from directly entering the air extraction pipe 3.

[0034] Furthermore, the arc-shaped profile of the arc-shaped piece 701 changes with the arc-shaped profile of the conical cover 502, and the planar projection profile of the arc-shaped piece 701 is trapezoidal; this facilitates the arc-shaped piece 701 to adapt to the shape of the conical cover 502, thereby making it easier for the arc-shaped piece 701 to fit well with the conical cover 502, which in turn facilitates the assembly of the filter assembly 7. Example

[0035] Compared with Embodiment 1, Embodiment 2 further discloses a snap-fit ​​component 8 based on Embodiment 1. A snap-fit ​​component 8 is provided between the filter component 7 and the through groove 6. The snap-fit ​​component 8 is used to connect the filter component 7 and the through groove 6. The snap-fit ​​component 8 includes: an outer frame 801, which is fixedly connected to the side of the through groove 6; a snap block 804, which is provided around the outer side of the outer frame 801; and a slot 802, which is provided on one side of the arc-shaped piece 701 and a guide groove 803 on one side of the slot 802. When it is necessary to replace the filter component 7, the protrusion is pushed outward. The plate 703 separates the rubber-made locking block 804 from the slot 802, thereby removing the entire filter assembly 7 from the side of the through groove 6. During installation, the guide groove 803 on the arc-shaped plate 701 is aligned with the locking block 804, allowing the locking block 804 to enter the slot 802 along the guide groove 803, thus facilitating the engagement of the slot 802 and the locking block 804. The inner contour of the slot 802 matches the outer contour of the locking block 804, and the inner contour size of the guide groove 803 decreases from the outside to the inside, thus facilitating the smooth engagement of the locking block 804 with the slot 802.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
