Description

Technical Field

[0001] This utility model relates to the field of caulking equipment technology, specifically to a caulking machine discharge structure. Background Technology

[0002] In construction and decoration projects, gaps are inevitable between bricks. When tiling walls and floors, gaps are usually left between the tiles to prevent them from cracking due to thermal expansion. These gaps are filled with grout to ensure the waterproofness of the floor. Grout guns are usually used for grouting. However, traditional grout guns require pushing the gun forward while grouting, and cannot automatically squeeze the grout, making the operation cumbersome.

[0003] In view of this, the inventors of this case conducted in-depth research on the above-mentioned problems, which led to the creation of this case. Utility Model Content

The fixed sleeve passes through the dispensing nozzle and the top sleeve from front to back and is fixedly sleeved on the dispensing pipe. The front side of the dispensing pipe is provided with several sealing rings for sealing contact with the fixed sleeve. The inner diameter of the small-diameter end of the fixed sleeve is smaller than the outer diameter of the large-diameter end of the dispensing nozzle to prevent the dispensing nozzle from falling out of the fixed sleeve. The cross-section of the dispensing nozzle is elliptical, circular, duckbill-shaped, or oblique.

[0007] Furthermore, in order to detachably install the discharge nozzle onto the discharge pipe using a fixing sleeve, the front side of the discharge pipe is provided with two annular grooves for installing sealing rings, the discharge pipe is provided with a fixing groove located behind the annular grooves, and the rear side of the fixing sleeve is provided with a pin hole corresponding to the fixing groove for inserting a fixing pin to fix the fixing sleeve onto the discharge pipe.

[0008] Furthermore, in order to drive the vibrating mechanism to vibrate through the screw conveyor mechanism, agitate the material, and ensure smooth discharge, the vibrating mechanism includes a vibrating rod, a driven wheel, and a driving wheel. The middle part of the vibrating rod is rotatably mounted on the hopper, the front side of the vibrating rod is located inside the hopper, and the rear side of the vibrating rod is located outside the hopper.

The sleeve is provided with a fixing member for coaxially fixing the sleeve to the rotating shaft. The wheel plate is coaxially fixedly installed on one side of the sleeve. The wheel plate is a regular hexagon or a regular octagon.

[0010] Furthermore, in order to ensure that the caulking machine can be filled with a large amount of material and that the filling operation time is long without frequent filling, the hopper includes a bottom chamber and an extension chamber located on the upper side of the bottom chamber. The bottom chamber is in the shape of an inverted quadrangular pyramid. The bottom of the bottom chamber is provided with a semi-circular plate adapted to the diameter of the discharge pipe. The upper side of the discharge pipe is provided with an opening for communicating with the bottom chamber. The top of the extension chamber is also provided with a cover.
