[0007] The bottom of the bag is located on the base, the expansion piece expands the opening of the bag, the first limit piece is located on one side of the bag, the heating piece is located on the other side of the bag and is opposite to the first limit piece. When the bag is filled with beans of a specified weight, the first limit piece moves, the heating piece abuts and fits against the first limit piece, and the upper end of the bag is located between the heating piece and the first limit piece. Since the opening of the bag is made of plastic, the heating piece and the first limit piece cooperate to heat-press and seal the opening of the bag.

[0008] Compared with the prior art, the beneficial effects of the present invention are:

[0009] The support member of the utility model can provide support for the bag, and the heating member and the first limiting member can cooperate to heat-press and seal the open part of the bag containing beans after weighing, thereby ensuring that the beans can be prevented from rolling out of the bag when the bag is transferred to the corresponding bean sprout growing basket.

[0010] As a preferred embodiment of the utility model, the sealing assembly further comprises a limiting frame, the heating element is located at one side of an upper end of the limiting frame, and the first limiting element is provided with a first cylinder for driving the first limiting element to adjust its position.

[0011] Beneficial effects: The design of the limit frame facilitates the subsequent robot to pass through and push the packaged bags to the conveyor belt. The design of the heating element located on the upper side of the limit frame ensures that the sealing part is located at the open end of the bag.

[0012] As a preferred embodiment of the utility model, a connecting member is provided between the first limiting member and the first cylinder, and the connecting member includes a symmetrically arranged connecting column, a first connecting block and a second connecting block respectively located at both ends of the connecting column, the first connecting block is connected to the heating member, and the second connecting block is connected to the first cylinder.

[0013] Beneficial effect: The design of the symmetrically arranged connecting column, the first connecting block and the second connecting block can ensure that when the heating element abuts and fits with the first limiting element, the heating element abuts and fits with the first limiting element at all locations, thereby ensuring that the bag opening is heat-pressed and sealed at all locations, ensuring effective sealing.

[0015] In this solution, the bottom of the bag is located on the base. When the beans of a specified weight are weighed, the outer edge of the bag's opening is located between the limiting ring and the opening ring. When the weighing is completed, the first cylinder is started and drives the first limiting member to approach the heating member. At the same time, the second cylinder is started, the limiting ring moves away from the opening ring, the bag's opening is movable, the first limiting member and the heating member are in contact and fit, and the bag's opening is located between the first limiting member and the heating member.

[0016] Beneficial effect: the second cylinder can adjust the position of the limiting ring, and the limiting ring and the opening ring cooperate to stably limit the bag.

[0017] As a preferred embodiment of the present invention, the support rod is an outwardly convex arc rod.

[0018] Beneficial effect: The outwardly convex arc rod design increases the space enclosed by the support rod and the base, and can accommodate bags containing beans of different specifications and weights.

[0019] As a preferred embodiment of the utility model, the diameter of the upper end of the expansion ring is larger than the diameter of the lower end, the upper end and the lower end of the expansion ring are connected in an arc, and the connection is concave inward, and the support rod is connected to the outer side of the expansion ring.

[0020] Beneficial effect: The design that the diameter of the upper end of the expansion ring is larger than the diameter of the lower end enables the expansion ring to fully abut against the limiting ring, thereby effectively limiting the open outer edge of the bag.

Figure 1 , 2 As shown, the expansion assembly includes an expansion member 2 for expanding the opening of the bag and a second limiting member for limiting the outer edge of the opening of the bag. The expansion member 2 includes symmetrically arranged support rods 201 and expansion rings 202 connected to the two support rods 201. The support rods 201 are arc-shaped rods convex outward. The upper end diameter of the expansion ring 202 is larger than the lower end diameter. The upper and lower ends of the expansion ring 202 are connected in an arc, and the connection is concave inward. One end of the support rod 201 is connected to the outer side surface of the expansion ring 202, and the other end is connected to the base 1.

[0031] like Figure 4 As shown, the second limiting member includes a second cylinder 9 for controlling the upper and lower position adjustment of the limiting ring 8, and a limiting ring 8 connected to the second cylinder 9. When the limiting ring 8 abuts against the outer edge of the upper end of the expansion ring 202, the outer edge of the bag opening is located between the limiting ring 8 and the expansion ring 202.

[0032] like Figure 2 , 3 As shown, the sealing assembly includes a first limit member 3, a heating member 4 and a limit frame 5. In the present embodiment, the first limit member 3 is a limit bar, and the first limit member 3 is provided with a first cylinder 6 for driving the position adjustment of the first limit member 3. A connecting member 7 is provided between the first limit member 3 and the first cylinder 6.

[0033] In this embodiment, the length of the first limit member 3 is smaller than the distance between the two support rods 201 and larger than the diameter of the lower end of the expansion ring 202. The upper surface of the first connecting block 702 can fit with the lower end surface of the expansion ring 202, ensuring that the first limit member 3 and the heating element 4 can cooperate to cover the open opening of the bag and effectively seal the open opening of the bag.

[0034] The heating element 4 is located on one side of the two support rods 201, the lower end of the limiting frame 5 is connected to the base 1, and the upper end is connected to the heating element 4, the heating element 4 is opposite to the first limiting element 3, when the heating element 4 is abutted against the first limiting element 3, the bag is located between the heating element 4 and the first limiting element 3, the upper surface of the first connecting block 702 is in contact with the lower end surface of the support ring 202, and the heating element 4 cooperates with the first limiting element 3 to heat-press and seal the open part of the bag.

When weighing is completed, the first cylinder 6 and the second cylinder 9 are started at the same time. Since the first limit member 3 and the heating member 4 are respectively located on both sides of the bag, the first cylinder 6 drives the first limit member 3 to approach the heating member 4, and the upper surface of the first connecting block 702 is in abutment with the lower end surface of the expansion ring 202. The second cylinder 9 drives the limit ring 8 to move upward away from the expansion ring 202. The first limit member 3 drives the bag to approach the heating member 4 and abut against each other to seal the bag's opening.
