Further, the number of the medicine outlet holes 14 is not less than 2, the number of the medicine outlet holes 14 is matched with the number of the first grooves 12, the outlet direction of the medicine outlet holes 14 shown in fig. 4 is inclined downwards, the included angle between the medicine outlet holes 14 and the first grooves 12 is α, wherein the included angle α is as follows: 90 < alpha be less than or equal to 180, even draw medicine hole 14 slope and set up downwards for the liquid medicine enters into out medicine hole 14 from second recess 21, and the liquid medicine receives the action of gravity downwards outflow valve body 1, tongue 7 sets up in the below of going out medicine hole 14 for accept out medicine hole 14 outflow liquid medicine, tongue 7 is U type connecting plate, installs between valve body 1 and valve gap 5, and sets up in the below of going out medicine hole 14, therefore it can accept out the liquid medicine that medicine hole 14 flows out, the one end of tongue 7 is provided with the breach that is used for the liquid medicine outflow. The liquid medicine from the medicine outlet holes 14 is collected on the tongue piece 7, and finally the liquid medicine flows out from the notch on the tongue piece 7 and is coated on the backing material.

Further, the periphery of the liquid storage bin 13 is provided with a plurality of through holes 131 for communicating the first grooves 12, the longitudinal section of the second grooves 21 is a circular structure, the number of the first grooves 12 is not less than 2, the number of the second grooves 21 is not less than 2, the number of the first grooves 12 is the same as that of the second grooves 21, the number of the through holes 131 is the same as that of the first grooves 12, and the through holes 131 are communicated with the first grooves 12 through pipelines. In this embodiment, the first groove 12 and the second groove 21 are 5 grooves, and the longitudinal section is cut along the length direction of the valve body.

Further, the moving assembly 4 comprises a cylinder 41 and a cylinder support 42, the cylinder 41 is connected with the cylinder support 42, the cylinder support 42 is fixedly connected with the valve cover 5, and a piston of the cylinder 41 is fixedly connected with the connecting rod 6. When the piston rod of the cylinder 41 moves, the valve rod 6 can be driven to move left and right, and the valve rod 6 can drive the valve core 3 to move left and right.

The principle of the embodiment is as follows:

when the coating work is carried out, the gear pump 9 driven by the servo motor 8 drives the liquid medicine into ointment coating equipment, wherein a medicine inlet 91 of the gear pump 9 is communicated with a container for storing the liquid medicine, a medicine outlet 92 of the gear pump 9 is communicated with an injection hole 11 of the valve body 1, the liquid medicine enters a liquid storage bin 13 from the injection hole 11, then the liquid medicine enters a first groove 12 from a through hole 131, meanwhile, the air cylinder 41 drives the valve rod 6 to move, so that a second groove 21 on the valve core 2 is communicated with the first groove 12 as shown in figure 3, sealing rings 22 are arranged on two sides of the second groove 21, the liquid medicine can enter the second groove 21 from the first groove 12 and downwards move to a medicine outlet 14 along the second groove 22 as shown in figure 4, finally, the liquid medicine flows out from a gap of the tongue piece 7 for coating, the liquid medicine downwards moves under the influence of gravity because the medicine outlet 14 is in a downward inclined angle, and when the medicine outlet 14 is vertical to the first groove 12, the liquid medicine velocity of motion is minimum, along with the contained angle increase of medicine outlet 14 and first recess 12, liquid medicine velocity of motion grow, and when medicine outlet 14 was located same vertical line with first recess 12, liquid medicine velocity of motion was the biggest, and in this implementation, the contained angle preferred scope of medicine outlet 14 and first recess 12 was 120 ~ 150, and medicine outlet 14 can prevent that the liquid medicine outflow rate is too fast this moment, and the coating that causes is inhomogeneous or pile up the liquid medicine scheduling problem.

In addition, the width of second recess 21 is different, and the flow of liquid medicine is also different, and when second recess 21 width equals the width of first recess, the liquid medicine flow is the biggest, and the liquid medicine that flows out valve body 1 is more, and the thickness of coating is bigger, and is on the contrary along with the width of second recess 21 diminishes, and the liquid medicine flow can diminish gradually, and the thickness of coating also can become thin, consequently in the production, can select the case of different widths according to different production demands.

Finally, in this embodiment, the movement range of the cylinder 41 can be controlled to further control the second groove 21 to be completely or partially communicated with the first groove 12, so as to further control the flow rate of the liquid medicine, realize the regulation and control of the coating thickness, and ensure the uniformity and timeliness of the coating.

When the coating stops working, the cylinder 41 drives the valve rod 6 to draw the valve core 2 to a closed position, the circulation passage of the liquid medicine is closed, the state of the valve core 2 is as shown in fig. 5, at the moment, the second groove 21 is not communicated with the first groove 12, and the sealing rings are arranged on two sides of the second groove 21, so that the liquid medicine cannot flow to the medicine outlet hole 14 along the periphery of the valve core 2.

Example two

In this example, motion subassembly 4 includes the motor, the side and the valve gap 5 fixed connection of motor, the rotor and the valve rod fixed connection of motor, wherein rotor, the valve rod of motor all are on same water flat line, and valve rod, case are all on same water flat line, and the motor drives when operation and drives the valve rod and do circular motion, and the valve rod can drive case 2 rotation again.

Further, the longitudinal section of the second groove 21 is in a circular arc structure, and the central angle of the circular arc is less than 180 °.

When coating work, the motor drives the valve rod to enable the valve core to rotate, so that the upper end of the second groove 21 is communicated with the first groove 12, and the lower end of the second groove 21 is communicated with the medicine outlet hole 14. Meanwhile, the gear pump 9 driven by the servo motor 8 pumps the liquid medicine into the ointment coating equipment, wherein a medicine inlet 91 of the gear pump 9 is communicated with a container for storing the liquid medicine, a medicine outlet 92 of the gear pump 9 is communicated with a filling hole 11 of the valve body 1, the liquid medicine enters the liquid storage bin 13 from the filling hole 11, then the liquid medicine enters the first groove 12 from the through hole 131, meanwhile, the air cylinder 41 drives the valve rod 6 to move, so that the second groove 21 on the valve core 2 is communicated with the first groove 12 as shown in fig. 3, the sealing rings 22 are arranged on two sides of the second groove 21, the liquid medicine can enter the second groove 21 from the first groove 12 and downwards move to the medicine outlet 14 along the second groove 22 as shown in fig. 4, and finally the liquid medicine flows out from a notch of the tongue piece 7 for coating.

When the coating stops working, the motor drives the valve rod to rotate the valve core to a closed position, the circulation passage of the liquid medicine is closed, and at the moment, the upper end of the second groove 21 is not communicated with the first groove 12, so that the liquid medicine cannot flow into the second groove 21. The valve core structure can close the channel in a drawing or rotating mode within a protection range

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
