Embodiment 1

[0028] Embodiment one, see figure 1 , figure 2 , image 3 with Figure 4 , a motor-driven pipeline switching mechanism, including a valve opening structure 5, an inner column 1, an outer ring 2 that is rotatably sleeved outside the inner column, and an outer ring drive mechanism 3 that drives the outer ring to rotate. An escape pit 21 is provided on the inner peripheral surface of the outer ring 2 . The escape pit 21 is a V-shaped pit. The end face of the inner column 1 is provided with a central hole 11 and several peripheral holes 12 surrounding the central hole. Each peripheral hole communicates with the central hole through a communication hole 13 . The communicating hole is a straight line structure. The communication hole is provided with an extension section 14 penetrating through the peripheral surface of the inner column. The extension section is a straight line structure. The communicating hole and the extension are located on the same straight line. The ap...

Embodiment 2

[0031] Embodiment two, with the different support of embodiment one:

[0032] see Figure 5 , Image 6 , Figure 7 , Figure 8 with Figure 9 , The central hole 11 is also provided with a connection joint 9 . The connecting joint includes a connecting pipe head 99, an internally threaded pipe section 91 arranged in the outer end of the central hole, and a positioning step 92 located at the inner end of the internally threaded pipe section. The outer end of the internally threaded pipe section is provided with a large-diameter section to form a first sealing step 93 . One end of the connecting pipe head 99 is provided with an externally threaded pipe section 94 . A second sealing step 95 is formed between the externally threaded pipe section and the connecting pipe head. The connecting pipe head 99 can be inserted into the large-diameter section. The externally threaded pipe section is threadedly connected with an internally and externally threaded pipe section 96 sleev...

Embodiment 3

[0036] Embodiment three, the difference with embodiment one is:

[0037] see Figure 10 , each plug 4 is provided with a valve opening structure 5 . The valve opening structure is a spring.

Abstract

The invention relates to a motor-driven pipeline switching mechanism. The motor-driven pipeline switching mechanism comprises an open-valve structure, an inner column, an outer ring and an outer ringdriving mechanism, wherein the outer ring and the outer ring driving mechanism are arranged outside the inner column in a rotating mode, receding pits are formed in the inner peripheral surface of theouter ring, a central hole and a plurality of peripheral holes surrounding the central hole are formed in the end surface of the inner column, each peripheral hole is in communication with the central hole through a communication hole, the communication hole is provided with an extending section which penetrates through the linear structure of the peripheral surface of the inner column, and a plug is movably arranged in the communication hole in a penetrating mode; all the plugs, only outer end of one plug can be located in the receding pits at the same moment; when the outer ends of the plugs are located in the receding pits, the plugs lose the sealing effect on the communication hole under the action of the opening valve structure; the outer ends of the plugs are staggered with the receding pits, and the plugs are sealed and closed in the communication hole under the extrusion action of the outer ring; the outer ring driving mechanism comprises a transmission and a driving motor which are connected together with the outer ring. The motor-driven pipeline switching mechanism is used for realizing communication control of the same pipeline of a plurality of pipelines.

Description

technical field [0001] The invention relates to a mechanical structure on traditional Chinese medicine production equipment, in particular to a motor-driven pipeline switching mechanism. Background technique [0002] In the automatic production equipment of traditional Chinese medicine, it is necessary to input a variety of different liquids into the same infusion main pipe through different pipelines and then transport them to the destination. At the same time, only one of the pipelines can be communicated with the infusion main pipe. Existing realization above connection is realized by electromagnetic valve. In addition, the existing method of sealing and detachable connection of two pipe bodies is to set thread heads on the ends of the two pipe bodies, and then wind the upper raw tape on the thread heads and screw them to connect the two ends of the internal thread pipe head The detachable connection is realized on the top, and the sealing is realized by the deformation...
