DETAILED DESCRIPTION

[0021] In order to further explain the technical solution of the present invention, specific embodiments are described in detail below.

[0022] See also Figure 1-2The utility model provides a vacuum packaging device for EVA granules, including a packaging device body 1, a controllable control panel 2 is provided at the top front end of the packaging device body 1, a hatch 3 is provided at the bottom end of the control panel 2, and the hatch 3 can be turned over to close a working chamber 4, and also includes a working chamber 4 provided at the middle end of the packaging device body 1.

[0023] See also Figure 2-4 The present invention provides a vacuum packaging device for EVA pellets. A vacuum mechanism body 41 is provided at the top of a working chamber 4. Support plates 42 are connected to the bottom ends of the left and right sides. The opposing surfaces of the two sets of support plates 42 are provided with corresponding grooves 421, and a placement mechanism 43 is connected through the grooves 421.

[0024] The placement mechanism 43 includes a placement plate 431 and a limiting plate 432. The left and right ends of the placement plate 431 can be connected to the grooves 421 of the two groups of support plates 42 respectively. The height of the placement plate 431 can be adjusted by connecting with grooves 421 of different heights. The top front end and the left and right ends of the placement plate 431 are each provided with no less than two groups of placement grooves 4311, and are connected to the limiting plate 432 through the placement grooves 4311. Among them, the length of the front and rear end placement grooves 4311 is greater than the length of the left and right end placement grooves 4311, but the width is the same to accommodate limiting plates 432 of different sizes.

[0025] See also Figure 2-5The utility model provides an air-evacuation packaging device for EVA granules. The limiting plate 432 includes a bottom plate 4321, a connecting plate 4322, a rotating plate 1 4323, a support seat 4324, a hinge 4325, a folding plate 4326 and a rotating plate 2 4327. The bottom surface of the bottom plate 4321 is provided with a connecting plate 4322 corresponding to the placement groove 4311. The bottom middle end of the connecting plate 4322 is rotatably connected to a group of rotating plates 1 4323. After the connecting plate 4322 is inserted into the placement groove 4311, the rotating plate 1 4323 can extend to the bottom surface of the placement plate 431. At this time, the bottom plate 4321 can be fixed to the top surface of the placement plate 431 by rotating the rotating plate 1 4323. The bottom end of the bottom plate 4321 is provided with a support seat 4324. The bottom end of the support seat 4324 can contact the placement plate 431, which can improve the stability of the bottom plate 4321. The left and right top ends of the outer side of the bottom plate 4321 are both connected by hinges 4325. At least two groups of folding plates 4326 are connected. The height of the limit plate 432 can be adjusted by folding the folding plates 4326 to accommodate packaging bags of different sizes and packaging quantities. A group of rotating plates 4327 are connected to the top middle end of the bottom plate 4321 near the hinge 4325 and the middle end of the folding plate 4326. After the rotating plates 4327 are rotated upward, they can be stuck in the outer middle end of the folding plate 4326 to limit and fix the folding plate 4326. Among them, the upper and lower groups of rotating plates 4327 are staggered with each other to avoid collision between the upper and lower groups of rotating plates 4327 during movement. Furthermore, the limit plates 432 are opposite to each other, and the front and rear groups of limit plates 432 are the same size, and the left and right groups of limit plates 432 are the same size. By replacing limit plates 432 of different sizes and inserting them into the placement slots 4311 at different positions, areas of different sizes can be formed to accommodate packaging bags of different sizes.

[0026] Here’s how it works:

[0027] During use, the hatch 3 can be opened, the placement plate 431 can be taken out, and then the limiting plates 432 of different sizes can be replaced according to the size of the required packaging quantity and the size of the packaging bag, and inserted into the placement grooves 4311 at different positions, and fixed by rotating the rotating plate 4323 so that the packaging bag can be placed therein, and the EVA particles in the packaging bag can be shaped by the bottom plate 4321 and the folding plate 4326, and then the placement plate 431 can be put back into the working chamber 4 and inserted into the groove 421 at the appropriate position, and then the opening of the packaging bag is connected to the exhaust mechanism body 41, and then the hatch 3 is closed, and the exhaust mechanism body 41 is controlled by the control panel 2 to perform exhaust packaging on the EVA particles, and finally the hatch 3 can be reopened, and the placement plate 431 and the packaged EVA particles can be taken out.
