the hollow shell 401 is vertically fixed on the upper part of the dispensing valve 20 and covers the dispensing valve 20, and a through hole 4011 is formed in the left side of the bottom in the hollow shell 401 to enable the outer protrusion 3011 to extend into the through hole; the piezoelectric ceramic 402 is vertically fixed at the right side of the upper part in the hollow shell 401; the supporting spring 404 is vertically fixed in the middle of the bottom of the hollow shell 401; the middle part of the bottom of the transverse lever 403 is fixedly arranged on the support spring 404, the left end of the transverse lever is positioned right above the convex 3011 and bends downwards to form a pressing part 4031, and the right end of the transverse lever abuts against the bottom of the piezoelectric ceramic 402;

initially, the supporting spring 404 is compressed, the piezoelectric ceramic 402 is shortened, and the left end of the transverse lever 403 is inclined downward, so that the pressing portion 4031 presses the protrusion 3011 downward.

When the main controller 405 controls the piezoelectric ceramic 402 to extend, the lower end of the piezoelectric ceramic 402 presses down the right end of the transverse lever 403, at this time, the left end of the transverse lever 403 tilts upward to enable the pressing portion 4031 to move upward, when the pressing portion 4031 moves upward, the outward protrusion 3011 is pushed up by the upper jacking spring 304, so that the needle rod 301 of the glue closing striker 30 moves upward, and the lower end of the needle rod 301 of the glue closing striker 30 opens the funnel-shaped nozzle 90, so that atomized glue solution is sprayed to a glue dispensing part on the surface of a product to be dispensed through the funnel-shaped nozzle 90.

Therefore, in the present application, the up-down driving member 40 includes the hollow housing 401, the piezoelectric ceramic 402, the transverse lever 403, the supporting spring 404 and the main controller 405 electrically connected to the piezoelectric ceramic 402 for controlling the extension or the shortening of the piezoelectric ceramic 402, and the main controller adopts the lever principle to drive the glue closing striker 30 to move up and down, so that the driving cost can be greatly reduced, the structure of the whole device can be greatly reduced, the volume can be reduced, the occupied space is small, and the use is convenient and fast, compared with the traditional lifting driving member such as the lifting cylinder, the screw rod transmission module and the like which are directly arranged on the upper part of the glue closing striker 30 to control the lifting of the glue closing striker 30.

In addition, in practical implementation, according to an embodiment of the present invention, the up-down driving member 40 further includes a striker stroke adjusting screw 406 for precisely controlling the ascending and descending stroke of the glue closing striker 30;

wherein, the stitching part 4031 is provided with a jack 40311 penetrating through the upper and lower end surfaces thereof; the left upper portion of the hollow housing 401 is provided with an elevation adjusting screw hole 4012 facing the jack 40311, the striker stroke adjusting screw 406 is screwed into the elevation adjusting screw hole 4012 from top to bottom, the lower end of the striker stroke adjusting screw extends into the jack 40311, and the outer diameter of the lower end of the striker stroke adjusting screw is smaller than the outer diameter of the jack 40311, so that when the left end of the transverse lever 403 is tilted upwards, the lower end of the striker stroke adjusting screw 406 does not block the pressing portion 4031 from moving upwards.

Therefore, it can be understood that when the main controller 405 controls the extension of the piezoelectric ceramic 402 to enable the lower end of the piezoelectric ceramic 402 to press down the right end of the transverse lever 403, the left end of the transverse lever 403 tilts upward, so that the pressing portion 4031 moves upward to enable the outward protrusion 3011 to be pushed up by the upward top spring 304, so as to enable the needle bar 301 of the glue closing striker 30 to move upward to open the funnel-shaped nozzle 90, and then to spray atomized glue solution to the glue dispensing part on the surface of the product to be dispensed through the funnel-shaped nozzle 90, in this process, the height of the striker stroke adjusting screw 406 can be manually adjusted to enable the upward movement stroke of the needle bar 301 of the glue closing striker 30 to be precisely controlled, and then the opening degree of the funnel-shaped nozzle 90 to be opened by the lower end of the needle bar 301 of the glue closing striker 30 to be precisely controlled, the amount of the glue solution sprayed out from the funnel-shaped nozzle 90 can be accurately controlled, so that the use is flexible, and the control can be flexibly carried out according to the glue amount requirement of the glue dispensing part on the surface of the product.

Therefore, through above-mentioned optimal design, on the whole, but this application accomplishes that the gas flow velocity can accurate control, but goes out gluey volume accurate control, but glue solution atomization degree accurate control for the result of use can reach the best.

In addition, in practical implementation, according to an embodiment of the present invention, the front end surface of the hollow housing 401 is provided with a detachable cover 4013, so as to facilitate the disassembly and assembly maintenance or replacement of various components inside the hollow housing 401.

Meanwhile, in a preferred embodiment, a piezoelectric ceramic stroke adjusting screw 407 screwed into the hollow housing 401 for adjusting the up-down position of the piezoelectric ceramic 402 is disposed at the upper right portion of the hollow housing 401, and the lower end of the piezoelectric ceramic stroke adjusting screw 407 abuts against the top of the piezoelectric ceramic 402, so that when the piezoelectric ceramic stroke adjusting screw 407 is screwed, fine adjustment of the position of the piezoelectric ceramic 402 in the up-down direction can be achieved, and the application is more flexible.
