Description

Technical Field

[0001] The utility model relates to the field of sealing equipment, in particular to a quick-detachable suction nozzle vacuum sealing machine. Background Art

[0002] The applicant's sealing machines are often used to seal the openings of packaging bags. For example, the heat sealer disclosed in utility model patent publication number CN214777019U monitors the sealing pressure. Two strip-shaped heat-sealing elements compress the plastic bag to be sealed. Some products require vacuuming the bag. Often, a retractable negative pressure nozzle is positioned between the two heat-sealing elements. This nozzle is inserted into the bag during the sealing process to vacuum the bag and then withdrawn near the end of the sealing process.

[0003] Currently, most negative pressure nozzles are fixed to the vacuum pump pipeline with screws. When the negative pressure nozzle needs to be disassembled (for disinfection, sterilization, maintenance, etc.), the operation process is relatively cumbersome and easily interfered with by heat sealing parts, causing inconvenience in disassembly. Based on this, the applicant proposed a quick-release nozzle vacuum sealer. Utility Model Content

[0025] To remove the suction nozzle 3 of the sealing machine of the present invention, one need only rotate the nozzle 3 so that the clamping block 4 disengages from the slot 5 and the nozzle 3 can be removed. To install the suction nozzle 3, one need only insert the fixing tube 301 into the negative pressure chamber so that the clamping block 4 enters the slot 5 at the opening and then rotate the fixing tube 301. The suction nozzle 3 of the present invention can be easily disassembled, achieving the technical effect of quick release. The connection structure between the suction nozzle 3 and the opening is simple and easy to manufacture.

[0026] It should be noted that the improvement of the present invention lies in the quick-release structure of the suction nozzle 3, and there is no restriction on the improvement of other structural components of the sealing machine. Those skilled in the art can flexibly choose the existing sealing components 1 (heat sealing strips, electromagnetic sealing parts, steam sealing parts) and vacuum components (vacuum pumps, vacuum generators), and moving parts of the suction nozzle 3 (such as electric telescopic rods, cylinders) when implementing it.

[0027] In a preferred embodiment, the structure of the present invention is further specifically described as follows: the clamping block 4 has a fixing hole for the fixing tube 301 to pass through, and the clamping block 4 includes an arcuate positioning edge 401 and a locking portion 402 protruding from the arcuate positioning edge 401. As shown in the figure, this allows the clamping block 4 to be sleeved and fixed to the fixing tube 301.

[0028] As shown in the figure, the card slot 5 has a notch for the locking portion 402 to enter. After the locking portion 402 enters the card slot 5 from the notch, it rotates to abut against the side wall of the card slot 5 to achieve the installation of the suction nozzle 3.

[0029] In a preferred embodiment, the structure of the present invention is further specifically described as follows: the arc-shaped positioning edge 401 is provided with a fixed flange 6 that fits the fixed tube 301, and the fixed flange 6 is welded to the fixed tube 301. As shown in the figure, this facilitates the fixing of the fixed tube 301 and the clamping block 4.

[0030] In a preferred embodiment, for the structure of the present invention, more specifically, the fixing tube 301 is inserted into the inner side of the negative pressure chamber.

[0031] In a preferred embodiment, for the structure of the present invention, to be more specific, a positioning step 7 abutting against the fixing tube 301 is provided in the negative pressure chamber, and a sealing ring 8 is installed at the position of the positioning step 7 .

[0032] As shown in the figure, by providing a positioning step 7, a limit can be formed on the fixed tube 301 inside the negative pressure chamber, and the sealing ring 8 is used to seal the connection position between the fixed tube 301 and the negative pressure chamber.

[0033] In the two types shown in the figures, the sealing ring 8 is configured as an annular sealing ring 8 that can be sleeved on the positioning step 7 .

[0034] In a preferred embodiment, for the structure of the present invention, to be more specific, a base tube 9 is provided in the fixing seat 2, and a mounting tube 10 is sleeved on the base tube 9.

[0035] As shown in the figure, by setting the base tube 9 and the mounting tube 10, the spring 11 abuts between the base tube 9 and the mounting tube 10, so that when the fixing tube 301 is inserted inward, the spring 11 can be compressed after the fixing tube 301 abuts against the positioning step 7, so that the mounting tube 10 moves inward together. At this time, the block 4 can be pushed into the slot 5. After the block 4 is rotated to complete the installation, the spring 11 drives the mounting tube 10 to push the fixing tube 301 outward, so that the block 4 is pressed against the side wall of the slot 5 to stabilize the suction nozzle 3, increase the friction between the block 4 and the side wall of the slot 5, and prevent the suction nozzle 3 from rotating at will.

[0036] In a preferred embodiment, for the structure of the present invention, to be more specific, the width of the slot 5 in the axial direction of the fixed tube 301 is greater than the width of the block 4, and the surface of the block 4 facing the mouth 302 and / or the inner wall of the slot 5 is provided with an anti-slip layer 12.

[0037] By providing the anti-slip layer 12 , when the spring 11 drives the mounting tube 10 to push the fixing tube 301 outward, the clamping block 4 can abut against the side wall of the clamping slot 5 through the anti-slip layer 12 , thereby preventing the fixing tube 301 from rotating.

[0038] In a preferred embodiment, for the structure of the present invention, more specifically, the anti-slip layer 12 is configured as a rubber anti-slip layer 12 .
