Description

Technical Field

[0001] The utility model relates to the technical field of bean sprout production, in particular to a bean sprout packaging machine. Background Art

[0002] After bean sprouts are produced, they need to be packaged before being transported to major supermarkets. The packaging of bean sprouts requires manual screening, manual bagging, manual sealing of packaging bags, and manual placement of packaging bags into storage baskets. Each step of bean sprout packaging requires manual operation, and the packaging efficiency is low. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the purpose of the utility model is to provide a bean sprout packaging machine, which automatically and quickly seals the packaging bags after the bean sprouts are manually screened and put into packaging bags, and automatically places the packaging bags on a conveyor belt, thereby reducing manual operation steps and improving packaging efficiency.

[0004] The technical scheme adopted by the utility model is as follows: a bean sprout packaging machine, comprising a base, a sealing component for sealing a packaging bag containing bean sprouts, and a conveying component for conveying the packaged packaging bag, wherein the base is symmetrically provided with a first limiting plate, one end of each of the two first limiting plates is provided with a limiting component, and a pushing component is provided between the other ends, the limiting component comprises a second limiting plate connected to the first limiting plate, the second limiting plate can rotate in the horizontal direction, the pushing component comprises a first cylinder, and a third limiting plate connected to the first cylinder, the third limiting plate is located between the two first limiting plates, and is respectively in contact with the surface of the corresponding first limiting plates, the conveying component comprises a conveyor belt, and the conveyor belt is close to the second limiting plate;

[0005] Before the packaging bag is sealed, the second limiting plate is perpendicular to the first limiting plate. The first space enclosed by the two first limiting plates, the two second limiting plates and the third limiting plate is used to accommodate the packaging bag containing bean sprouts and to limit the packaging bag containing bean sprouts to be sealed. The sealing assembly seals the packaging bag. The piston rod in the first cylinder moves along the length direction of the first limiting plate. The third limiting plate pushes the packaged packaging bag containing bean sprouts toward the conveyor belt. The second limiting plate rotates horizontally relative to the first limiting plate. The packaging bag is located on the conveyor belt. The piston rod in the first cylinder returns to the initial position, and the second limiting plate returns to the initial position.

[0006] Principle of the technical solution:

[0007] Before the packaging bag is sealed, the second limiting plate is perpendicular to the first limiting plate, and the packaging bag containing bean sprouts is placed in a first space enclosed by the two first limiting plates, the two second limiting plates, and the third limiting plates. The two first limiting plates cooperate to limit one opposite side of the packaging bag containing bean sprouts, and the two second limiting plates and the third limiting plates cooperate to limit the other opposite side of the packaging bag containing bean sprouts, and the sealing assembly seals the packaging bag; after the sealing is completed, the piston rod in the first cylinder moves along the length direction of the first limiting plate, and drives the third limiting plate to move along the length direction of the first limiting plate. The third limiting plate pushes the packaged packaging bag to move along the length direction of the first limiting plate. Since the second limiting plate can rotate horizontally, the packaging bag drives the second limiting plate to rotate horizontally when moving along the length direction of the first limiting plate, so that the packaging bag passes between the two second limiting plates and is pushed onto the conveyor belt. The above operations are repeated, and finally the packaging is transported and packaged together.

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

[0009] The two first limiting plates, the two second limiting plates, and the third limiting plates of the utility model cooperate to accommodate the packaging bag containing bean sprouts and automatically limit the packaging bag, and can quickly assist in straightening the packaging bag so that the two sides of the upper end of the packaging bag are aligned, so that when the sealing component seals the packaging bag, it can seal with the two sides of the upper end of the packaging bag aligned, thereby improving the sealing quality. The design that the two second limiting plates can rotate horizontally, the first cylinder is connected to the third limiting plate, and the packaging bag is located in the enclosed first space can ensure that the packaging bag is automatically pushed onto the conveyor belt after the sealing is completed, and can automatically and quickly seal the packaging bag after the bean sprouts are manually screened and loaded into the packaging bag, and automatically put the packaging bag on the conveyor belt to wait for centralized transportation and packaging, thereby reducing manual operation steps and improving packaging efficiency.

One end of the second connecting plate is connected to the second limit plate, and the other end is rotatably connected to the connecting shaft. The torsion spring is sleeved on the connecting shaft and respectively abuts against the first limit plate and the second limit plate.

[0011] Beneficial effect: The design of the first connecting plate, the second connecting plate and the connecting shaft can ensure the stable connection between the second limit plate and the first limit plate, and can ensure that the second limit plate can rotate horizontally. In addition, the design of the torsion spring can ensure that the second limit plate automatically returns to the initial state after horizontal rotation, that is, after the second limit plate rotates horizontally, it automatically returns to the initial position under the action of the elastic force of the torsion spring, and the second limit plate is perpendicular to the first limit plate.

[0012] As a preferred embodiment of the present invention, the sealing assembly includes a heating element and a fourth limiting plate located above the first limiting plate, and the first limiting plate and the heating element are both connected to a second cylinder.
