Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments. In the following description, specific details are provided, such as specific configurations and components, merely to facilitate a thorough understanding of embodiments of the invention. Thus, it will be apparent to those skilled in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the invention. In addition, descriptions of well-known functions and constructions are omitted for clarity and conciseness.

Referring to fig. 1 to 5, the milk box piercing device includes: the device comprises a shell 1, a first guide groove and a second guide groove, wherein an inverted U-shaped guide groove 11 is formed in the shell; the needle assembly 2 can slide up and down in the U-shaped guide groove 11, and the needle assembly 2 is provided with a needle 21 which can pierce a milk box and suck milk; the chain 3 is arranged in the U-shaped guide groove 11, and one end of the chain 3 is connected with the needle assembly 2; the chain wheel 4 is matched with the chain 3 and can drive the chain 3 to move along the U-shaped guide groove 11; and a motor 5 for driving the chain wheel 4 to rotate.

Specifically, the motor 5 drives the chain wheel 4 to rotate, the chain wheel 4 drives the chain 3 to move, the chain 3 moves along the inverted U-shaped guide groove 11, and the pricking pin assembly 2 connected to one end of the chain 3 moves up and down. The lancet 21 on the lancet assembly 2 can pierce the milk carton downwards and suck up the milk in the milk carton. The milk box puncturing device drives the chain 3 to move through the chain wheel 4, so as to drive the puncture needle assembly 2 to move, and the needed driving components are fewer, the structure is compact, and the noise is low.

In some embodiments, the milk-box piercing means further comprises a first travel switch 6 on the upper side for defining the highest position of movement of the lancet assembly 2, and a second travel switch 7 on the lower side for defining the lowest position of movement of the lancet assembly 2.

The first travel switch 6 is used for limiting the highest position of the movement of the needle assembly 2, and the second travel switch 7 is used for limiting the lowest position of the movement of the needle assembly 2, so that the needle assembly 2 moves back and forth within a certain height range to realize the function of puncturing a milk box to suck milk.

In some embodiments, the housing 1 has an elongated hole 12 provided in the up-down direction for mounting the second stroke switch 7; the second travel switch 7 can be adjusted in the up-down position along the elongated hole 12. The second stroke switch 7 is used to define the lowest position of movement of the lancet assembly 2, and when the mounting height of the second stroke switch 7 changes, the lowest height of its reciprocating movement changes accordingly. The height of the second travel switch 7 can be adjusted accordingly according to the specific height of the milk box.

In some embodiments, the first and second travel switches 6, 7 are each micro-switches; the lancet assembly 2 is provided with a projection 22 for activating the micro-switch.

Specifically, the highest height is reached when the projection 22 on the lancet assembly 2 triggers the first travel switch 6, at which time the motor 5 reverses direction causing downward movement of the lancet assembly 2; the lowest height is reached when the projection 22 on the lancet assembly 2 activates the second travel switch 7, at which time the motor 5 reverses direction causing upward movement of the lancet assembly 2.
