Description

Technical Field

[0001] This utility model relates to the field of resin sand production technology, specifically to a resin sand production device. Background Technology

[0002] Resin sand is a composite material formed by mixing resin with sand particles. It is widely used in the foundry industry. Resin sand cores have high strength and hardness, which can maintain the precise size and shape of castings and reduce casting deformation and defects.

[0003] Chinese Patent Publication No. CN208245737U discloses a "Resin Sand Production Device," comprising a screw conveyor and a mixing device connected to the screw conveyor. A feeding pipe is provided between the mixing device and the screw conveyor, and a detachable discharge port is provided between the feeding pipe and the mixing device. A magnetic sieve plate is provided inside the feeding pipe. The mixing device includes a mixing drum containing helical mixing blades connected to a motor for driving their rotation. A hollow jacket is provided on the outer wall of the mixing drum, containing coolant. The outer wall of the jacket is hinged to the screw conveyor via a first connecting rod. The mixing device is also connected to a drive cylinder. This resin sand production device can ensure uniform mixing of the resin sand and simultaneously cool the resin sand during mixing, slowing down the hardening rate of the resin sand.

[0004] While existing technologies can stir materials, they cannot quantitatively control the amount of material added during use. The amount of raw materials added is difficult to control precisely, which may result in too much or too little raw material entering the production process. This leads to inconsistent proportions of materials such as sand, curing agent, and resin, affecting the uniformity and stability of the mixture. In addition, the stirring direction is unidirectional and the stirring time is long, which can easily create stirring dead zones in the mixing container. That is, in some areas, the stirring action of the blades is not reached or is weak, resulting in uneven mixing of materials such as sand, curing agent, and resin in these areas. Utility Model Content

[0005] The purpose of this invention is to provide a resin sand production device to solve the problems in the prior art where the amount of material added cannot be quantitatively controlled during use, the amount of raw materials added is difficult to control precisely, and too much or too little raw material may enter the production process, resulting in inconsistent proportions of materials such as sand, curing agent and resin, affecting the uniformity and stability of the mixture. At the same time, the stirring direction is unidirectional and the stirring time is long during use, and it is easy to form stirring dead zones in the stirring container, that is, in some areas the stirring action of the blades is not reached or the action is weak, resulting in uneven mixing of materials such as sand, curing agent and resin in these areas.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a resin sand production device, including a mixing tank, wherein a metering component is provided on the top of the mixing tank, and a mixing component is provided inside the mixing tank;

[0007] The quantitative component includes a feeding box, and a power column is rotatably embedded inside the feeding box. A feeding disc is fixedly connected to the outer surface of the power column. A discharge funnel is fixedly connected to the top of the outer surface of the feeding box. The feeding box is fixedly connected to the top of the outer surface of the mixing tank.

[0008] The stirring assembly includes a fixed plate, and a rotating rod is rotatably embedded inside the fixed plate. A lower connecting plate is fixedly connected to the outer surface of the rotating rod, and multiple lower stirring plates are fixedly connected to the outer surface of the lower connecting plate. A connecting cylinder is rotatably embedded inside the fixed plate, and an upper connecting plate is fixedly connected to the outer surface of the connecting cylinder. Multiple upper stirring plates are fixedly connected to the outer surface of the upper connecting plate. The rotating rod is rotatably embedded inside the connecting cylinder.

[0009] Preferably, a motor plate is fixedly connected to one side of the outer surface of the feeding box, and a feeding motor is provided on the top of the outer surface of the motor plate, and the output shaft of the feeding motor is fixedly connected to the power column.

[0010] Preferably, a power gear is fixedly connected to the outer surface of the rotating rod, a first rotating column is rotatably embedded inside the fixed plate, and an upper transmission gear is fixedly connected to the outer surface of the first rotating column, the outer surface of the upper transmission gear meshing with the second rotating column.

[0011] Preferably, a second rotating column is rotatably embedded inside the fixed plate, and a lower transmission gear is fixedly connected to the outer surface of the second rotating column, the outer surface of the lower transmission gear meshing with the upper transmission gear.

[0012] Preferably, a connecting gear is fixedly connected to the outer surface of the connecting cylinder, and the outer surface of the connecting gear meshes with the lower transmission gear, and the rotating rod is rotatably embedded inside the connecting gear.

[0013] Preferably, a stirring motor is fixedly connected to the top of the outer surface of the fixed plate, and the output shaft of the stirring motor is fixedly connected to the rotating rod.

[0014] Preferably, the outer surface of the mixing tank is fixedly connected with multiple support legs, and the interior of the mixing tank is provided with a discharge port.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0016] Firstly, this invention uses a feeding funnel to add raw materials and curing agents into the feeding box. By activating the feeding motor on top of the motor plate, the output shaft of the feeding motor is fixedly connected to a power column. The feeding motor drives the power column to rotate, which in turn drives the connected feeding disc to rotate. The rotating feeding disc then transports the material inside the feeding funnel into the mixing tank. The feeding disc delivers material with each rotation. This technical solution ensures that the proportions of sand, curing agent, and resin remain consistent each time they are fed, thus guaranteeing the uniformity of the mixture. This is crucial for improving the quality and performance of castings.

[0017] Secondly, this utility model utilizes a stirring motor located at the top of a fixed plate. The output shaft of the stirring motor is fixedly connected to a rotating rod, which is rotatably embedded inside a connecting cylinder and a connecting gear. The rotating rod connects to a lower connecting plate, directly driving the lower connecting plate and the lower stirring plate to rotate. When the rotating rod rotates, it drives the connected power gear to rotate, which in turn drives the geared upper transmission gear to rotate. The upper transmission gear then drives the geared lower transmission gear to rotate, which in turn drives the geared connecting gear to rotate. Through the transmission between the upper and lower transmission gears, the connecting gear and the rotating rod rotate in opposite directions. The connecting gear connects to the upper connecting plate via the connecting cylinder, driving the upper connecting plate and the upper stirring plate to rotate. The stirring motor drives the lower and upper stirring plates to rotate in opposite directions. This technical solution creates a more complex fluid motion, allowing materials such as sand, curing agent, and resin to be more thoroughly mixed within the mixing tank. This helps eliminate the dead zones caused by unidirectional stirring and ensures the uniformity of the mixture. Attached Figure Description
