Description

Technical Field

[0001] The utility model relates to the technical field of silica gel production, in particular to a quantitative feeder. Background Art

[0002] The main component of silica gel is silicon dioxide, which has stable chemical properties and is non-flammable. In the production process of silica gel, in order to improve the mechanical strength of raw rubber, it is necessary to add reinforcing materials, i.e. materials, to the raw rubber. In order to improve the production efficiency of silica gel, a feeder is needed, but the existing feeder still has the following shortcomings:

[0003] For example, the utility model with application number 202122116916.1 discloses a powder feeder for silica gel production. In the utility model, a motor, a cylindrical rod and fan blades are arranged in cooperation with a hollow tube and a water tank, so that the problem of powder splashing and diffusion will not occur during the process of adding powder and depressurizing the equipment, which is beneficial to protecting the health of operators and reducing powder waste. However, similar to the comparative documents of the above-mentioned application, when the existing feeders are used, since most feeders are not convenient for quantitatively and accurately controlling the amount of feed during silica gel production, the subsequent silica gel product quality is easily affected, resulting in a decrease in the practicality of the feeder and a decrease in its use efficiency.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a quantitative feeder is proposed. Utility Model Content

[0014] The utility model provides a quantitative feeder, which has the following beneficial effects:

[0015] 1. The utility model can avoid the situation that most feeders are not convenient for quantitatively and accurately controlling the feeding amount during silicone production when using a quantitative feeder through the setting of a quantitative component, which makes the subsequent silicone product quality easily affected and causes the practicality of the feeder to decrease. The feed pipe is connected to the collecting hopper via fasteners, so that the screened material enters the quantitative cylinder through the collecting hopper and the feed pipe. The output shaft of the servo motor installed on the left side of the quantitative cylinder is connected to a threaded rotating rod through a coupling. The operation of the servo motor drives the threaded rotating rod to rotate inside the quantitative cylinder, and the outer part of the threaded rotating rod is tightly fitted with the inner wall of the quantitative cylinder, so that the material entering the quantitative cylinder through the feed pipe is quantitatively sent out through the feeding pipe as the threaded rotating rod rotates, thereby increasing the overall use efficiency of the feeder.

[0016] 2. The utility model can avoid the problem that most feeders do not have the material screening performance when using the quantitative feeder, which makes the feeder unable to process the agglomerated raw materials, thereby affecting the subsequent production of silica gel and causing the problem of reduced efficiency of the feeder by setting the screening component. The drive motor is fixedly installed on one side of the outside of the feeding chamber through fasteners, and the output shaft of the drive motor is connected to the first crushing roller through a coupling. The drive motor drives the first crushing roller to rotate, and cooperates with the second crushing roller embedded outside the first crushing roller to crush the material added to the inside of the feeding chamber. The limit frame is fixedly installed at the rear end of the screening frame. The output shaft of the synchronous motor outside the limit frame is connected to the lead screw through a coupling. The operation of the synchronous motor drives the lead screw to rotate, so that the movable slider connected to the outside of the lead screw slides left and right inside the limit frame, and the movement of the movable slider drives the installation cross plate to move inside the screening frame, and the crushed materials are intercepted by the filter screen arranged inside the screening frame. The movement of the installation cross plate drives the screening brush to move, and the screening brush breaks up the material agglomerated on the surface of the filter screen and allows the material to enter the collecting hopper, thereby increasing the activeness of the feeder during use.
