Description

Technical Field

[0001] The invention mainly relates to the technical field of powder material extraction equipment, in particular to a uniform material extraction mechanism. Background Art

[0002] In the process of plastic injection molding, plastic particles or powders are first added to the hopper, and then the plastic material is melted by heating. Then, under the action of pressure, the molten plastic is injected into the mold cavity through the pouring system. After the plastic fills the cavity, the pressure is maintained to ensure the density of the product. The plastic part is then solidified through the mold's cooling system. After the plastic part is cooled and solidified, the mold is opened and the product is taken out. Finally, the gate, runner and other pouring systems on the product are cut off.

[0003] In the process of adding materials to the feed hopper, a pumping device is required. The current pumping device mainly includes an air pump, a hose and a pumping head, such as the attached Figure 6 and attached Figure 7 As shown, the upper end of the hose is connected to an air pump, and the lower end is connected to a suction head, and the suction head is inserted into a container containing powder. Under the action of the air pump, the powder is sucked from the hose into the feed hopper. However, by extracting in this way, the powder near the suction head will be quickly absorbed, while the area far away from the suction head will be absorbed more slowly, resulting in uneven absorption on the powder belt. Therefore, in the industry, this processing step has always had problems of high energy consumption and low efficiency. Since sufficient air pressure is required, the air pump will run very fast, which will cause powder splashing during high-speed absorption, polluting the working environment, making nearby workers susceptible to respiratory diseases, and in severe cases, there may be a risk of dust explosion. Summary of the invention

[0004] The technical solution of the present invention aims at the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technologies. Specifically, the present invention mainly provides a uniform extraction mechanism to solve the technical problem raised in the above background technology that in the current process of processing plastic parts, the extraction of powdered raw materials is not uniform enough, resulting in high energy consumption and low efficiency in this step.

[0005] The technical solution adopted by the present invention to solve the above technical problems is: A uniform extraction mechanism comprises a feeding device and a support table, wherein the feeding device comprises a feeding hopper and a pump body, wherein the output end of the pump body is connected to an interface on the upper side of the feeding hopper, and the input end of the pump body is provided with an anti-blocking and unblocking component, wherein the anti-blocking and unblocking component comprises a guide hose, a bent pipe and a tray, wherein the upper end of the guide hose is connected to the input end of the pump body, and the lower end of the guide hose is connected to the bent pipe, and the tray is located at the upper end of the bent pipe, and an oscillation exhaust component is installed on the tray by screws, and the oscillation exhaust component comprises a transition cavity, wherein micro-oscillators are arranged around the outer wall of the transition cavity, and a feeding speed control component is arranged on the upper side of the transition cavity, and wherein the feeding speed control component comprises a shell, and a plurality of rotating shafts are linearly arranged at equal intervals at the opening of the shell, and a baffle is arranged on each of the rotating shafts.

[0006] Preferably, an installation cavity is provided at the edge position of the upper side of the shell, and one end of the rotating shaft is inserted into the installation cavity, a pulley is provided at one end of the rotating shaft located at the two side positions, two pulleys are provided at one end of the rotating shaft located at the middle position, and a belt body is provided between two non-coaxial adjacent pulleys, and the pulley and the belt body are located in the installation cavity.

[0007] Preferably, a second motor is disposed on one side of the outer wall of the shell, and an output end of the second motor is connected to one end of the corresponding rotating shaft.

[0008] Preferably, a cover plate is mounted on the upper side of the mounting cavity by screws.

[0009] Preferably, angle irons are provided at the edge positions around the shell, and the angle irons are installed at the opening positions on the lower side of the support platform by screws.

[0010] Preferably, a plurality of limiting plates are arranged around the inner wall of the transition cavity at equal intervals, limiting grooves are arranged on both sides of each limiting plate, and an arc heating plate is arranged between the two limiting grooves on two adjacent limiting plates.

[0011] Preferably, a circular groove is provided at the opening position on the upper side of the tray, a special-shaped bracket is provided in the circular groove, a placement groove is provided at the center position of the special-shaped bracket, a first motor is provided in the placement groove, and a stirring member is provided at the output end of the first motor.

[0012] Preferably, the stirring member comprises an intermediate shaft, upper blades and lower blades.

[0013] Preferably, a control box is mounted on one side of the outer wall of the pump body by bolts.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention realizes that when extracting powdered materials, the size of the discharge port is changed under the action of the rotating shaft, the baffle, the pulley and the belt body, so as to first control the flow rate of the powder material to avoid the formation of gullies on the pipeline due to excessive flow rate, thereby affecting the uniformity. Then, the distance between the powder particles is changed by the cooperation of the transition cavity and the micro-oscillator, so that the distance between the powder particles is smaller, the gas is discharged, the proportion of air is reduced, and the uniformity of the extraction is further improved. The special-shaped bracket, the placement groove, the first motor and the stirring member cooperate with each other, so that the powder material is stirred before entering the bent pipeline, and the flow rate of the powder material is avoided at the bend when the material is in a lump or too much material is discharged. The mixer is composed of an intermediate shaft, an upper blade and a lower blade, which can optimize the flow rate, prevent the blockage at the bend in advance, and further improve the stability of the extraction. In summary, the uniformity of extraction is optimized one by one through three steps, thereby ensuring the quality of the powder material, improving the work efficiency, and having greater economic benefits. (2) The present invention realizes that the side wall of the transition cavity vibrates when the powdered material passes through the transition cavity by setting a transition cavity and a micro-oscillator, thereby preventing the powdered material from adhering to the inner wall of the transition cavity and condensing into agglomerates, thereby avoiding interference with the subsequent flow of the powdered material. The powdered material is heated by the cooperation between the limit plate, the limit groove and the arc heating plate. Since the material is stored in a warehouse for a long time before use, the moisture content in the material increases and it is easy to form small agglomerates. Therefore, under the action of heating and vibration, the moisture in the material is evaporated, which is conducive to the loosening of the small agglomerates and avoids subsequent blockage in the pipeline. At the same time, the probability of spots, bubbles or other defects on the plastic parts after injection molding, which affects the appearance quality, is reduced, thereby improving the quality of the product.

[0015] (3) The present invention realizes the combined use of a soft tube and a hard tube in the process of extracting materials by arranging a feed hopper, a pump body, a control box, a guide hose, a bent pipe and a tray. A hard pipe is used at the bottom bend position, thereby avoiding the direct use of a soft tube in the prior art, which reduces the inner diameter of the hose at the bend (not greater than ninety degrees) and easily causes material accumulation and blockage, especially when the powder fluidity is poor. At the same time, it prevents the generation of a large shear force at the bend (not greater than ninety degrees) of the hose, which affects the particle size distribution of the material. The combination of soft and hard tubes not only makes it convenient to change the position of the pipeline, but also optimizes the circulation of the powder.
