Description

Technical Field

[0001] The utility model belongs to the technical field of low-molecular wax processing, and particularly relates to a stirring mechanism for low-molecular wax. Background Art

[0002] In the casting industry, low-molecular wax is often used as a raw material to cast molds. During the process of using low-molecular wax to make wax, a stirring device is often used to stir the wax liquid to ensure the stable performance of the wax, thereby improving the surface quality of subsequent castings.

[0003] The Chinese utility model patent with the publication number of CN209771921U discloses a stirring mechanism for low-molecular wax, which includes a stirring shaft and stirring blades installed on the stirring shaft. One end of the stirring shaft and the stirring blades are located at the center of the raw material barrel, and the other end of the stirring shaft is fixed to the driving shaft of the rotary driving device; the above patent can ensure the stable performance of the wax, effectively avoid problems such as foaming, looseness, and easy breakage during the wax-making process, thereby improving the quality of the product, and is convenient for replacing the stirring blades, which can reduce the equipment investment cost.

[0004] However, the above patent has the following deficiencies:

[0005] 1. The above patent adjusts the height of the stirring shaft and the stirring blades through a lifting driving device (cylinder). This adjustment method cannot apply force to the bottom of the rotary driving device to complete the height adjustment of the stirring blades. For the adjustment by applying force to the top of the rotary driving device through the lifting driving device, it often limits the lifting range of the stirring shaft and the stirring blades due to the volume occupied by the lifting driving device itself, and the stirring blades cannot be completely separated from the raw material barrel. Summary of the Utility Model

[0006] The utility model provides a stirring mechanism for low-molecular wax, aiming to solve the problem that when adjusting by applying force to the top of the rotary driving device through a lifting driving device at present, it often limits the lifting range of the stirring shaft and the stirring blades due to the volume occupied by the lifting driving device itself, and the stirring blades cannot be completely separated from the raw material barrel.

[0007] To achieve the above purpose, the utility model adopts the following technical scheme:

[0008] A stirring mechanism for low-molecular wax, comprising a mounting plate. A stirring tank is installed on the top of the mounting plate. A stirring mechanism is arranged above the stirring tank. A lifting mechanism is provided on the side wall of the stirring mechanism. The stirring mechanism is connected to the mounting plate through the lifting mechanism. A driving mechanism is provided at the bottom of the mounting plate. The driving mechanism is used to provide driving force for the lifting mechanism. The lifting mechanism includes a first lead screw. The first lead screw is located on one side of the stirring tank and is rotatably connected to the mounting plate. A first nut is threadedly connected to the side wall of the first lead screw.

In this solution, by setting the first lead screw and the first nut, when the first lead screw rotates, it can drive the first nut to move up and down the left end of the lifting plate on the first guide post, thereby controlling whether the stirring blades extend into the stirring tank.

[0009] Preferably, a second lead screw is provided on the side of the stirring tank away from the first guide post. The second lead screw is rotatably connected to the mounting plate. A second nut is threadedly connected to the side wall of the second lead screw. A second guide post is arranged between the second nut and the stirring tank. The second guide post is fixedly connected to the mounting plate. A second guide block is sleeved on the side wall of the second guide post.

In this solution, by setting the second lead screw and the second nut, when the second lead screw rotates, it will drive the second nut to move up and down the right end of the lifting plate on the second guide post. This device can apply force to both ends of the lifting plate simultaneously. Compared with only lifting one end of the lifting plate, this device can make the stirring mechanism lift stably.

[0010] Preferably, the driving mechanism includes a first driving motor. The first driving motor is located below the mounting plate.

A second transmission wheel corresponding to the first transmission wheel is sleeved on the side wall of the transmission shaft. A transmission belt is arranged between the first transmission wheel and the second transmission wheel. The first transmission wheel and the second transmission wheel are connected through the transmission belt. In this solution, by setting the first driving motor, the first transmission wheel, the second transmission wheel and the transmission belt, the above components can drive the first lead screw and the second lead screw to rotate synchronously to realize the synchronous rise or fall of both ends of the lifting plate.

[0011] Preferably, the stirring mechanism includes a bracket located on and fixedly connected to the lifting plate. A second driving motor is installed on the bracket. A stirring shaft is arranged below the lifting plate. The stirring shaft is fixedly connected to the output shaft of the second driving motor. The bottom of the stirring shaft has a connecting shaft, and the connecting shaft is detachably connected to the stirring shaft. A plurality of stirring blades are installed on the side wall of the connecting shaft. In this solution, by setting the second driving motor, the second driving motor can drive the stirring shaft and the plurality of stirring blades on the connecting shaft to rotate, so as to perform a stirring operation on the materials in the stirring tank.

A second connecting plate is arranged at the bottom of the first connecting plate. The second connecting plate is fixedly connected to the connecting shaft. The first connecting plate and the second connecting plate are detachably connected.

[0013] Preferably, bolts are arranged on both sides of the stirring shaft. Both bolts penetrate through the first connecting plate and the second connecting plate. There are two nuts at the bottom of the second connecting plate. The two nuts are respectively screwed to the two bolts. In this solution, by setting the bolts and nuts, it is convenient to remove the stirring blades on the connecting shaft from the stirring shaft for maintenance.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. By setting the lifting mechanism and the driving mechanism, when the first driving motor in the driving mechanism works, it can simultaneously drive the first lead screw and the second lead screw in the lifting mechanism to rotate. At this time, the first nuts and the second nuts on the first lead screw and the second lead screw respectively drive the two ends of the lifting plate to perform a rising action or a falling action, so as to control whether the stirring blades in the stirring mechanism extend into the stirring tank. Compared with using a cylinder to adjust the height of the stirring blades, the device of the present application will not be limited by the occupied volume of the cylinder itself, resulting in a limited lifting range of the stirring blades. And the lifting method of the device of the present application is more stable and will not cause the stirring blades to shift in the horizontal direction when moving in the vertical direction.
