As a specific embodiment of the device for stirring and preparing the adhesive for metal powder provided by the present invention, please refer to fig. 3, a clamping groove engaged with the sealing strip 13 is formed along the outer edge of the packing auger 9. If the scraper is arranged on the outer edge of the auger 9 and if the whole scraper is made of a flexible material, the scraper needs to be deformed and abut against the inner wall of the discharging barrel 11 in order to achieve a good conveying effect, and although the conveying effect is good, the result is that the resistance of the whole auger 9 during movement is large and the scraper is seriously worn. And if the spatula is made of a metal material, the spatula is not easy to process and manufacture, so that the sealing strip 13 is arranged on the outer edge of the packing auger 9, and the sealing strip 13 is made of a wear-resistant flexible material, so that the conveying effect and long-term use are ensured.

As a specific embodiment of the adhesive stirring preparation apparatus for metal powder according to the present invention, the sealing strip 13 is adhered to the inside of the clamping groove. The sealing strip 13 is long in length, and in order to stabilize the sealing strip 13 at a specific position of the packing auger 9, namely to improve the interaction force between the sealing strip 13 and the packing auger 9, the clamping groove is a dovetail groove, and the sealing strip 13 and the clamping groove are bonded and fixed at the same time.

Referring to fig. 1 and 2, a collecting sleeve 2 is disposed between a solution tank 1 and a discharging cylinder 11, and a cross section of the collecting sleeve 2 decreases downward. The viscosity of the components for preparing the adhesive is generally high, and if the bottom of the solution tank 1 is set at a right angle, the fluidity at that point is poor and it is difficult to remove. In order to avoid the above reasons, a confluence sleeve 2 is provided at the bottom of the solution tank 1, and the confluence sleeve 2 itself may be regarded as a tapered structure, so that various components in the solution tank 1 can be converged downwards.

Referring to fig. 1 and 2, a limiting sleeve 5 is inserted between a solution tank 1 and a collecting sleeve 2. When needs preparation heterogeneous adhesive, need clear up solution tank 1 and collection flow sleeve 2 after last adhesive preparation is accomplished, if solution tank 1 and collection flow sleeve 2 fixed connection, need the effect that the clearance just can be guaranteed to a large amount of water of filling usually, this just influences normal production and has caused the waste of resource, adopts split type design at solution tank 1 and collection flow sleeve 2 for this reason, mentions solution tank 1 and can carry out corresponding clearance operation.

Referring to fig. 1 and 2, as a specific embodiment of the device for stirring and preparing the adhesive for metal powder according to the present invention, the top and the bottom of the position-limiting sleeve 5 are both provided with a clamping groove, and the two clamping grooves are respectively in insertion fit with the solution tank 1 and the collecting sleeve 2. Stop collar 5 itself is annular component, and the quantity of draw-in groove is two, and two draw-in grooves distribute in the upper and lower both sides of stop collar 5, place stop collar 5 at the top of collection flow sleeve 2 earlier when actual installation, then install solution tank 1.

Referring to fig. 1 and 2, a sealing ring 12 is disposed in the clamping groove, and the sealing ring 12 is used to seal a gap between the clamping groove and the solution tank 1 and a gap between the clamping groove and the collecting sleeve 2. After the solution tank 1 and the converging sleeve 2 are respectively clamped and matched with the limiting sleeve 5, the sealing ring 12 positioned in the clamping groove is pressed and deformed by means of the gravity of the solution tank 1, and the like, so that the tightness is ensured, and the leakage of components is avoided.

As a specific embodiment of the adhesive stirring preparation apparatus for metal powder according to the present invention, a plurality of positioning pins are installed on the position-limiting sleeve 5, and the positioning pins are screwed to the position-limiting sleeve 5 and abut against the outer wall of the solution tank 1. Because the motor need be connected on the top of pivot 8 to can produce the vibration at pivot 8 rotation in-process, for guaranteeing solution tank 1 for stop collar 5's stability, can be on stop collar 5 a plurality of locating pins of threaded connection, for further stability improvement, can set up the constant head tank with locating pin joint complex at solution tank 1's outer wall.

Referring to fig. 1 and 2, as a specific embodiment of the device for stirring and preparing the binder for metal powder according to the present invention, a heating jacket 3 is sleeved on an outer wall of a solution tank 1, and a heat insulating jacket 4 is disposed outside the heating jacket 3.
