Description

Technical Field

[0001] The utility model belongs to the technical field of extruders, in particular to an extruder discharge port. Background Art

[0002] Extruder is a type of plastic machinery. According to the direction of material flow in the die and the angle between the center line of the screw, the die head can be divided into right-angle die head and bevel die head.

[0003] Currently, after extrusion and pelletizing, TPV materials in China are commonly subject to static electricity adsorption at the discharge port. This is particularly prevalent when pelletizing requirements are low, especially when pellets of varying shapes are adsorbed. When this occurs, manual pellet removal is required. Furthermore, because the pellets contain static electricity, they easily adhere to the surrounding container. Manual removal is time-consuming and labor-intensive, significantly increasing labor costs.

[0004] For this purpose, we propose an extruder discharge port. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art that TPV particles are easily adsorbed on the discharge port and around the container due to static electricity, which makes manual stripping time-consuming and labor-intensive, and increases labor costs, and to propose an extruder discharge port.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] An extruder discharge port, comprising:

[0008] A discharge pipe installed on one side of the extruder discharge port is used to guide the extruded material to flow out smoothly. An air inlet hole is opened through the outer wall of one side of the discharge pipe to introduce air into the discharge pipe. A material blocking mechanism is installed in the air inlet hole to prevent particles from flowing out of the air inlet hole.

[0009] A connecting frame, the connecting frame is fixedly mounted on an outer wall of one side of the discharge pipe, the connecting frame is connected to the air inlet, an upper mounting tube is fixedly passed through the top of the connecting frame, and a lower mounting tube is fixedly mounted on the bottom inner wall of the connecting frame;

[0010] The ion wind rod is installed on the inner side of the upper mounting tube, and the bottom end of the ion wind rod is located in the lower mounting tube. The outer wall of the ion wind rod is provided with a nozzle for ejecting air masses, and the nozzle is arranged in the direction of the air inlet, so that the air mass can be ejected directly in the direction of the air inlet and enter the discharge pipe to contact the particles.

[0011] The material shifting mechanism is arranged on the inner side of the discharge pipe and is used for shifting the particles.

[0012] In one possible design, the material blocking mechanism includes an air inlet frame, which is fixed to the inner wall of the air inlet hole. The top inner wall and the bottom inner wall of the air inlet frame are fixed with a plurality of equally spaced blocking bars, and the spacing between the blocking bars is smaller than the size of the particles, thereby effectively blocking the particles from passing through the air inlet hole.

[0013] In a possible design, two symmetrically arranged inclined surfaces are provided on one side of the baffle to guide the air mass into the discharge pipe to reduce resistance.

[0014] In one possible design, the material-moving mechanism includes a motor, which is fixed on the outer wall of one side of the discharge pipe. One end of the motor output shaft passes through the discharge pipe and is fixed with a rotating shaft. The outer wall of the rotating shaft is fixed with two surrounding shifting plates. The shifting plates can move the particles to lift them, thereby facilitating the contact between the air mass and the particle surface. A groove is provided on one side of the shifting plate. The groove not only helps to reduce the weight of the shifting plate, but also can accommodate and guide the material particles to a certain extent. The inner wall of the groove is provided with multiple through holes, which can facilitate the air mass to pass through and contact with the particle surface, thereby facilitating the neutralization of static electricity.

[0015] In a possible design, the size of the through-hole is larger than the size of the particles, and the particles can freely fall through the through-hole during the lifting process, thereby achieving the effect of breaking up the particles.

[0016] In one possible design, two positioning strips are fixed on the outer wall of the ion wind rod, and two positioning grooves are provided on the inner walls of the upper mounting tube and the lower mounting tube. The positioning strips and the positioning grooves cooperate so that the ion wind rod can be accurately installed in the designated position.

[0017] In a possible design, a top screw is passed through the outer wall thread of the upper mounting tube to limit the ion wind rod to prevent the ion wind rod from moving at will, and the installation and disassembly are convenient, which facilitates the subsequent maintenance of the ion wind rod.

[0018] In a possible design, a rubber pad is bonded to one end of the top screw, and the rubber pad contacts the ion wind rod, which can reduce the wear of the ion wind rod caused by the rotation of the top screw and extend the service life of the equipment.

[0019] In the present application, when in use, the particles pass through the discharge pipe, and then the ion wind rod is started, and the ion wind rod blows out air masses with positive and negative charges. The air masses are guided by the inclined surface and pass through the gaps of the baffle bars into the discharge pipe. The air masses come into contact with the particles, and the static electricity on the surface of the particles is neutralized. At the same time, the motor is started, and the motor drives the rotating shaft to rotate, and the rotating shaft drives the paddle to rotate. The paddle paddle paddles the particles to lift them up, and the particles fall freely during the lifting process, achieving the effect of local dispersion, increasing the contact area between the air masses and the surface of the particles, and improving the effect of static electricity removal.

[0020] Beneficial effects:

[0021] In the utility model, the extruder discharge port is provided with multiple structures such as an ion wind rod, an air inlet hole and a top screw. The ion wind rod can generate a large number of air masses with positive and negative charges, so that the static electricity on the surface of the particles is neutralized, thereby achieving the purpose of eliminating static electricity and preventing the particles from adhering to the discharge port and the inner wall of the container. Manual peeling is not required, thus saving labor costs.

[0022] In the utility model, the extruder discharge port can stir and lift particles through the setting of the material digging mechanism, which can partially break up the particles, increase the contact area between the particles and the air mass, and improve the static electricity removal effect;

[0023] The utility model can neutralize static electricity on the surface of the particles, prevent the particles from adhering to the discharge port and the inner wall of the container, and does not require manual peeling, saving labor costs. It can also move and lift the particles to increase the contact area between the particles and the air mass, thereby improving the static removal effect. BRIEF DESCRIPTION OF THE DRAWINGS
