Detailed implementation manners

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only partial embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0019] Embodiment 1 As Figures 1 - 4 shown, a rapid packing device for selected tobacco leaves includes a mobile chassis 1. Support frames 2 are symmetrically arranged on two opposite sides of the mobile chassis 1. The bottom end of the support frame 2 is rotatably connected to the mobile chassis 1, and the upper end is provided with a sack opening and closing structure 3. The sack opening and closing structure 3 can be opened into a ring shape adapted to the sack mouth or closed into a straight shape, and a plurality of sack clamping mechanisms 4 are arranged on the sack opening and closing structure 3.

[0020] The mobile chassis 1 includes a bottom plate 101. A universal wheel set 102 is provided at the bottom of the bottom plate 101, and first hinge mechanisms 5 are provided at the four corners of the top. The bottom end of the support frame 2 is rotatably connected to the bottom plate 101 through the first hinge mechanism 5, and the upper end is connected to the sack opening and closing structure 3 through the second hinge mechanism 6. It can move freely on a weighing scale flush with the ground through the universal wheel set 102, which is convenient for weighing and saves time and effort in operation.

[0021] The support frame 2 is an H-shaped bracket formed by splicing vertical rods 201 and cross rods 202. The vertical rods 201 and the cross rods 202 are aluminum profile rods, which are light and easy to carry.

[0022] The first hinge mechanism 5 includes first shaft seats 501 provided at the four corners of the bottom plate 101. The bottom ends of the vertical rods 201 of the support frame are rotatably connected to the bottom plate 101 through rotating shafts provided on the first shaft seats 501. An outer stop block 502 is provided on the outside of the first shaft seat 501 and on the side of the bottom plate 101, and an inner stop block 503 is provided inside the first shaft seat 501. The outer stop block 502 is arranged vertically upward, and the inner stop block 503 is provided with an inclined surface on the side close to the first shaft seat 501 to enable the support frame 2 to rotate and move inward. When two opposite support frames 2 rotate outward, they can be attached to the outer stop block 502, thereby maintaining a vertical state. At this time, the sack opening and closing structure 3 at the top of the support frame 2 can be opened along with the support frame 1. When two opposite support frames 2 rotate inward, the rotation can be limited through the inner stop block 503, and after the tops of the support frames 2 approach each other, the sack opening and closing structure 3 can be closed along with the support frame 2.

[0023] To ensure the stability of the device, a self-locking structure is provided between the inner stop block 503 and the bottom end of the vertical rod 201 of the support frame, and between the bottom end of the vertical rod 201 of the support frame and the outer stop block 502, so as to realize the rotational locking of the support frame.

[0024] The self-locking structure can be a magnetic attraction structure, a screw locking structure, a bolt locking mechanism, etc.

[0025] The second hinge mechanism 6 includes a second shaft seat 601 provided at the top end of the vertical rod 201 of the support frame. The sack opening and closing structure 3 is rotatably connected to the top end of the vertical rod 201 through a hinge shaft 602 provided on the second shaft seat 601.

[0026] The sack opening and closing structure 3 is formed by splicing a plurality of lightweight rods 301. Adjacent lightweight rods 301 can be connected to each other through a third hinge mechanism 302. The lightweight rods 301 can be aluminum profiles. Specifically, the sack opening and closing structure is at least formed by splicing six aluminum profiles, including two long rods corresponding to the long sides of the rectangular bottom plate and four short rods corresponding to the short sides of the rectangular bottom plate. The top ends of the vertical rods of the support frame are hinged to the long rods for the installation and fixation of the sack opening and closing structure, and the short rods can be hinged through a hinge structure and the short rods and the long rods can be connected to each other through the third hinge mechanism 302 to realize the opening or closing adjustment of the sack opening and closing structure 3.

[0027] The sack clamping mechanism 4 is any fixture such as an elastic clip, a grab clip, a hook, etc. that can clamp the sack mouth. A plurality of fixtures are evenly distributed on the sack opening and closing structure 3.

[0028] Alternatively, a slide rail 401 is provided on the sack opening and closing structure 3. A plurality of fixtures are provided and are all slidably connected to the slide rail 401 through slide seats 402, and their positions on the sack opening and closing structure 3 can be adjusted according to actual use needs, and the adjustment flexibility is good.

[0029] Embodiment 2 As Figure 5 shown, on the basis of Embodiment 1, the post-selection tobacco leaf rapid packing device further includes a tobacco leaf compaction mechanism 7 provided on one side of the support frame 2.

[0030] The tobacco leaf compaction mechanism 7 includes a base 701 connected to the mobile chassis 1. An expansion mechanism 702 is provided on the base 701. The bottom of the expansion mechanism 702 is connected to the base 701, and the top end is provided with a connecting rod 703 extending directly above the sack opening and closing structure 3. A pressing plate 704 is provided at the end of the connecting rod 703.

[0031] The expansion mechanism 702 is an electric telescopic rod or a hydraulic cylinder.

[0032] The connecting rod 703 is a lightweight U-shaped rod. One end of the lightweight U-shaped rod is detachably connected to the end of the telescopic rod of the expansion mechanism 702. The other end is detachably connected to the pressing plate 702. Specifically, one end of the lightweight U-shaped rod can be detachably connected to the end of the telescopic rod of the expansion mechanism 702 through a screw sleeve structure, a bolt connection structure, etc. The other end of the lightweight U-shaped rod can be detachably connected to the pressing plate 704 through a bolt connection structure, a clamping structure, a magnetic attraction structure, etc.

[0033] The pressing plate 704 can be a lightweight aluminum plate, a plastic plate, etc. A number of weight-reducing groove holes are provided on the pressing plate.

[0034] The working principle and process of the device are as follows: (1) Move the device onto the weighing device, and hang the edge of the sack on the hook in the closed state of the device; (2) Manually open the device to the expanded state, and this state can be self-locked to maintain the expanded state without manual intervention. At this time, the worker can fill the sack with tobacco leaves until the required weight is reached, and then stop filling; (3) Make the pressing plate of the tobacco leaf compaction mechanism enter the sack to compact the tobacco leaves; (4) Manually close the sack opening to the closed state, sew it, and then remove the hook, thus completing the rapid weighing and packing.

[0035] The above description is only a preferred embodiment of the present invention, and does not impose any form of confidentiality restriction on the present invention. Any simple modification, equivalent change and modification made to the above embodiments without departing from the content of the technical solution of the present invention and based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
