Feeding device for assembling and driving agitator by magnetic principle

The present invention relates to a feeding device for assembling and driving a stirrer by using a magnetic attraction principle, in particular to a feeding device which is provided with a magnet on a driving motor to fix the adsorption agitator so that the agitator can rotate therewith.

According to today's industries, there are often demand for blending of thick materials, such as soy cream in the food industry, food sauces such as mustard sauce, ointments in the medical industry, water-mixed lime in betel nut, industrial or painting. Color mud...etc. In the past, such thick materials were manually blended and taken (eg, through multiple procedures such as digging, scraping, and squeezing), but because the staff used thick materials every time. The quantity is unstable and the efficiency of the manual method is not good. Therefore, it will not only affect the quality of the final product, but also prevent the operator from controlling the inventory of thick materials.

In order to solve the foregoing problems, the inventors have developed a feeding device A. Referring to Figure 1, the feeding device A includes a container A1 and a body A2, wherein the container A1 can be inserted and locked. And the like, assembled to the top surface of the seat body A2, can be filled with a thick material, and is provided with a stirrer A12 to fully stir the thick material; a groove A11 is formed in the inner surface of the container A1. The thick material can flow out of the container A1 via the channel A11.

The seat body A2 is provided with a discharge flow channel A21, a motor A22, a driving member A221, a piston portion A23 and a discharge nozzle A24, wherein the discharge flow channel A21 is horizontally disposed. And communicating with the channel A11, so that the thick material flowing out of the channel A11 can flow into the discharge channel A21, and one end of the discharge channel A21 can be extended to one end of the piston portion A23. The other end is connected to the discharge nozzle A24. Further, the motor A22 is connected to the driving member A221, and can drive the driving member A221 to horizontally reciprocate. The driving member A221 and the piston The other end of the portion A23 is connected to synchronously drive the piston portion A23 when it is displaced by itself, so that when the worker activates the motor A22, the motor A22 sequentially drives the driving member A221 and the piston portion A23 horizontally. When reciprocating left and right, one end of the piston portion A23 can push the thick material, and the thick material flows out through the discharge nozzle A24.

However, when the inventor actually uses it, it is found that the above-mentioned feeding device A has a number of problems in use. Referring to FIG. 1 , the container A1 is fixed to the seat body A2 through an assembly portion A10. And the assembly part A10 has to protrude into the inside of the container A1, and is connected with the agitator A12 to ensure the stability of the rotation of the agitator A12. However, since there may be an assembly gap between the bottom of the container A1 and the assembly part A10, Therefore, during the operation of the feeding device A, the thick material may ooze out of the assembly gap, causing trouble in cleaning.

It can be seen from the foregoing that the conventional feeding device has the problem that "the thick material is easy to assemble and leak out", although this problem can be prevented by controlling the product yield or installing a watertight structure, but it increases the production cost, so How to solve the problem of seepage without affecting the operation efficiency of the feeding device A is an important problem to be solved by the present invention.

In view of the problem of osmosis of the conventional feeding device, the inventor has, after many years of research, testing and improvement, based on years of practical experience, finally designed a method of assembling and driving the agitator using the magnetic principle. The feeding device can effectively solve the aforementioned defects.

An object of the present invention is to provide a feeding device for assembling and driving a stirrer by using a magnetic attraction principle, comprising a carrier, a container body, a stirrer and a driving mechanism, wherein the carrier is provided with a first driving motor The top portion is provided with at least one first magnet, and the first magnet is connected to the driving shaft of the first driving motor through a connecting arm, so that the first magnet can be used when the first driving motor is started. The drive shaft of the first drive motor is rotated centrally; the container is positioned on the carrier, the container body is provided with a stirring tank and a lead-out slot, and the stirring tank is used for filling a thick material, the export The trough is in communication with the agitation tank, and a discharge port is arranged at the bottom thereof; the agitator is installed at the bottom of the agitation tank, and at the bottom is provided with at least one magnetic conductive element, the position of the magnetic conductive element is The first magnet corresponds to be adsorbed and driven by the first magnet, so that the agitator can stir the thick material in the stirring tank to uniformly mix the components in the thick material; the driving mechanism is provided with a drive a rod, one end of the driving rod is movably inserted into the lead-out groove, and is provided with a piston portion, and in the case that the driving mechanism is activated, the driving rod can be displaced in the lead-out groove to introduce the thick material To the lead-out slot, and through the piston portion, the thick material in the lead-out groove is further pushed out of the discharge port. In this way, the magnetic attraction force of the first magnet and the magnetic conductive element can not only simplify the assembly complexity, but also avoid the problem of bleeding caused by the assembly gap between the container body and the carrier.
