[0022] EMBODIMENT

[0023] As Figures 1-4 shown, a kind of vacuum packaging machine, including vacuum packaging machine body 1, conveying belt 2, set clamping seat 4, top seat 41 and fixed mechanism, conveying belt 2 is installed on the top of vacuum packaging machine body 1, vacuum packaging machine body 1 top is movably provided with the vacuum cover 3 for covering the packaging bag between clamping seat 4 and top seat 41, conveying belt 2 can be conveyed to vacuum packaging machine body 1 top vacuum packaging bag in vacuum cover 3, to carry out vacuum packaging to Zongzi etc., vacuum packaging machine body 1, conveying belt 2 and vacuum cover 3 form existing chain-driven vacuum packaging machine, its internal specific structure and principle have been disclosed, here not too much repetition.

[0024] As Figures 1-3As shown, the clamping seat 4 and the top seat 41 are arranged on the top of the conveying belt 2, and a pressing rod 42 for pressing and clamping the bag opening of the packaging bag is rotatably arranged between the two sides of the clamping seat 4. The opening end of the packaging bag can be clamped and fixed by rotating the pressing rod 42, and the other end of the packaging bag can be limited by the top seat 41. After vacuum packaging, the top seat 41 can top the packaged packaging bag when the conveying belt 2 rotates, thereby facilitating the discharging.

[0025] As shown in the Figures 2-4 , the fixing mechanism is arranged on the top of the conveying belt 2 and is used for fixing the clamping seat 4 and the top seat 41. A plurality of convex holes 21 are formed in the outer wall of the conveying belt 2. The fixing mechanism comprises a plurality of limiting plates 51 slidably arranged in the clamping seat 4 and the top seat 41, two groups of elastic rods 52 symmetrically arranged on one side of the limiting plate 51, and an arc block 53 fixed on one side of the elastic rod 52 and located in the convex hole 21. The clamping seat 4 and the top seat 41 are both threadedly provided with a fixing screw 54. One end of the fixing screw 54 is rotatably provided with a pressing plate 56 abutting against the outer wall of the limiting plate 51. A tapered block 57 is fixedly arranged on one side of the pressing plate 56 and is used for supporting and fixing the arc block 53 in the two ends of the convex hole 21 after moving to the side of the conveying belt 2. The clamping seat 4 and the top seat 41 can support and fix the fixing screw 54. The two adjacent elastic rods 52 are arranged in a "8" shape.

[0026] As shown in the Figures 2-4 , the clamping seat 4 and the top seat 41 are both provided with a limiting groove 5. The limiting plate 51 and the pressing plate 56 are both slidably connected in the limiting groove 5. The clamping seat 4 and the top seat 41 can limit the limiting plate 51 and the pressing plate 56 through the limiting groove 5, so that the limiting plate 51 and the pressing plate 56 can only move up and down.

[0027] As shown in the Figures 2-4 , the nut of the fixing screw 54 is rotatably connected in the hidden groove arranged on one side of the clamping seat 4 and the top seat 41. The screw rod of the fixing screw 54 is fixedly provided with a rotating block 55 rotatably connected in the pressing plate 56. The clamping seat 4 and the top seat 41 can hide the nut of the fixing screw 54 through the hidden groove. The rotating block 55 can connect the fixing screw 54 and the pressing plate 56, so that the fixing screw 54 rotates to drive the pressing plate 56 to move up and down.

[0028] After rotating the fixing screw 54, the fixing screw 54 will drive the pressing plate 56 to move to the side of the limiting plate 51 under the connection of the rotating block 55, so as to press and fix the limiting plate 51 in the limiting groove 5. At this time, the two groups of elastic rods 52 and the arc block 53 on one side of the limiting plate 51 will straightly enter the plurality of convex holes 21. The tapered block 57 will move to the middle of the two groups of elastic rods 52 while the pressing plate 56 moves, so as to support and open the two groups of elastic rods 52 and fix the arc block 53 in the two ends of the convex hole 21, thereby quickly fixing the clamping seat 4 and the top seat 41.

[0029] After the reverse rotation of the fixing screw 54, the pressing plate 56 will move reversely to separate from the limiting plate 51, and the conical block 57 will move away from the middle of the two groups of elastic rods 52, at this time, the two groups of elastic rods 52 will move to the center of the convex hole 21 under the self elasticity, so that the arc-shaped block 53 separates from the two ends of the convex hole 21, at this time, the clamping seat 4 and the top seat 41 can be directly lifted to disassemble the clamping seat 4 and the top seat 41.

[0030] It should be noted that the vacuum packaging machine can clamp and fix the opening end of the packaging bag by rotating the pressing rod 42, can limit the other end of the packaging bag by the top seat 41, and can convey the packaging bag to the vacuum cover 3 for vacuumizing to package the zongzi and other articles.

[0031] The fixing mechanism can be used to fix and install the clamping seat 4 and the top seat 41 at different positions of the conveying belt 2, so as to conveniently adjust the distance between the clamping seat 4 and the top seat 41, and clamp and limit the packaging bags of different specifications and sizes.

[0032] When the clamping seat 4 and the top seat 41 need to be fixed, the fixing screw 54 will drive the pressing plate 56 to move to the side of the limiting plate 51 under the connection of the rotating block 55 after the rotation of the fixing screw 54, so as to press and fix the limiting plate 51 in the limiting groove 5, at this time, the two groups of elastic rods 52 and the arc-shaped block 53 on one side of the limiting plate 51 will enter the convex holes 21 directly, the conical block 57 will move to the middle of the two groups of elastic rods 52 while the pressing plate 56 moves, so as to open the two groups of elastic rods 52 and press and fix the arc-shaped block 53 in the two ends of the convex hole 21, to quickly fix the clamping seat 4 and the top seat 41.

[0033] When the clamping seat 4 and the top seat 41 need to be disassembled, the fixing screw 54 can be reversely rotated, the pressing plate 56 will reversely move to separate from the limiting plate 51, and the conical block 57 will move away from the middle of the two groups of elastic rods 52, at this time, the two groups of elastic rods 52 will move to the center of the convex hole 21 under the self elasticity, so that the arc-shaped block 53 separates from the two ends of the convex hole 21 and gathers to the middle part of the convex hole 21, at this time, the clamping seat 4 and the top seat 41 can be directly lifted to disassemble the clamping seat 4 and the top seat 41.

[0034] The above-described embodiments only express several implementation manners of the present application, the description is relatively specific and detailed, but it cannot be understood as the limitation of the patent scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
