[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example:

[0025] See also Figure 1-Figure 2The utility model provides a loading and unloading assembly of a checkweighing scale, including a checkweighing scale platform 1, a loading assembly 2 is arranged at the feeding end of the checkweighing scale platform 1, and a unloading assembly 3 is arranged at the discharging end of the checkweighing scale platform 1, the loading assembly 2 includes a first fixed plate 201, a first movable plate 202, a first spring 203 and a plug hole 204, the first movable plate 202 is movably installed on the top of the first fixed plate 201, the first fixed plate 201 is fixedly connected to the frame of the checkweighing scale platform 1, the first movable plate 202 is located above the checkweighing scale platform 1, and the first fixed plate 201 is fixedly installed with the first spring Spring 203, the first spring 203 supports the first movable plate 202, and the two sides of the first movable plate 202 are symmetrically provided with plug holes 204. The blanking component 3 includes a second fixed plate 301, a second movable plate 302 and a second spring 303. The second fixed plate 301 is fixedly installed with the frame of the checkweigher platform 1, and the second movable plate 302 is movably installed on the top of the second fixed plate 301. The second movable plate 302 is flush with the conveyor belt of the checkweigher platform 1. The second spring 303 is fixedly installed on the second fixed plate 301, and the second spring 303 supports the second movable plate 302.

[0026] Specifically, Figure 1 and Figure 2 As shown, the first fixed plate 201 and the second fixed plate 301 are provided with inclined surfaces, the lower side surfaces of the first movable plate 202 and the second movable plate 302 are raised to form an inclined platform, one end of the first spring 203 and the second spring 303 is fixed on the inclined surface, and the other end of the first spring 203 and the second spring 303 supports and contacts the inclined platform, so that when the first movable plate 202 and the second movable plate 302 are tilted, the first spring 203 and the second spring 303 are prevented from being compressed and twisted.

[0027] Specifically, Figure 1 As shown, the insertion hole 204 is opened at the inclined platform position and can be opened to a deep depth, so that the stability is good after the limit rod is inserted.

[0028] Specifically, Figure 1 and Figure 2 As shown, the sides of the first movable plate 202 and the second movable plate 302 are located outside the sides of the first fixed plate 201 and the second fixed plate 301. The slopes generated by the downward inclination of the first movable plate 202 and the second movable plate 302 are longer and have a smaller inclination, can be connected to the conveyor belt, and have good buffering performance.

[0029] Working principle:

[0030] When in use, the conveyor belt can be docked horizontally and vertically at the position of the first movable plate 202. If the conveyor belt is perpendicular to the direction of the checkweigher platform 1, a limit rod is installed at the position of the socket 204 at the relative position of the conveyor belt. If the items transported to the first movable plate 202 are blocked by the limit rod, they will stop moving by inertia and stop. The dead weight of the items moved to the first movable plate 202 on the conveyor belt docked horizontally and vertically presses the first spring 203 to descend, the first movable plate 202 is tilted, and the items fall onto the checkweigher platform 1 for weighing. A pushing cylinder can be installed on the side of the checkweigher platform 1 to push away unqualified items, and qualified items are moved to the second movable plate 302. The dead weight of the items presses the second movable plate 302 to tilt, and a horizontal or vertical conveyor belt is installed at the lower position of the second movable plate 302. The items fall onto the conveyor belt. After the items on the loading assembly 2 and the unloading assembly 3 fall, the first spring 203 and the second spring 303 will lift up the first movable plate 202 and the second movable plate 302 to restore them to their original state.
