Description

Technical Field

[0001] This utility model relates to the field of plastic extruder technology, specifically to a feeding mechanism for a plastic extruder. Background Technology

[0002] CN217196816U discloses a dust prevention mechanism for feeding a single-screw plastic extruder, comprising: a housing, a feeding mechanism mounted on the top of the housing, and an extrusion mechanism and a corresponding collection mechanism mounted inside the housing; the feeding mechanism includes an L-shaped conveying housing inserted into the top of the housing and a feeding housing connected to the other end of the conveying housing; a mounting housing is inserted into the top of the conveying housing; a fan is mounted on the upper part of one side wall of the mounting housing, and the output end of the fan communicates with the inner cavity of the mounting housing; multiple ventilation fans are installed side by side inside the inner cavity of the mounting housing; and a filter screen corresponding to the ventilation fans is nested at the bottom of the conveying housing. This dust prevention mechanism for feeding a single-screw plastic extruder removes dust from the raw material before extrusion and can separate debris from the extruded finished product.

[0003] Although the technical solution of the dust prevention mechanism for feeding the single-screw plastic extruder has the advantage of making it easy to remove dust from inside the raw material, the defects are also more obvious. For example, during the material feeding process, it is not easy for personnel to perform anti-blocking operations inside the feeding equipment, resulting in low material feeding efficiency and affecting subsequent processing by the processing personnel. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a feeding mechanism for a plastic extruder, which solves the problem that during the material feeding process, it is difficult for personnel to perform anti-blocking operations inside the feeding equipment, resulting in low material feeding efficiency and affecting subsequent processing by processing personnel.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a feeding mechanism for a plastic extruder, comprising a feeding box, a fixed frame fixedly installed on the top of the feeding box, a feeding hood provided on the top of the fixed frame, connecting rods fixedly connected to both sides of the outer surface of the feeding hood, a fixed plate fixedly installed on the top of the connecting rods, and a stirring assembly provided in the middle of the top surface of the fixed plate.

[0006] In one specific embodiment, the stirring assembly includes a drive motor fixedly connected to the top of the fixed plate, a T-shaped rod fixedly installed at the output end of the drive motor, and connecting rods fixedly connected to both sides of the bottom of the T-shaped rod.

[0007] In one specific embodiment, a collection box is fixedly connected to the center of the front of the feeding box, and a dust pump is fixedly installed in the center of the top surface of the collection box.

[0008] In one specific embodiment, a suction pipe is inserted into the output end of the vacuum pump, and one end of the suction pipe is inserted into the inside of the fixed frame.

[0009] In one specific embodiment, the inner wall of the fixed frame is provided with a cavity, and a filter screen is embedded on the surface of the cavity. The pore size of the filter screen is smaller than the diameter of ordinary plastic particles.

[0010] In one specific embodiment, a discharge pipe is inserted into the middle of the bottom surface of the feeding box, and a valve is provided on one side of the discharge pipe.

[0011] In one specific embodiment, support legs are fixedly installed on both sides of the bottom of the feeding box, and a transparent baffle is provided on one side of the feeding box.

[0012] Compared with the prior art, the present invention provides a feeding mechanism for a plastic extruder, which has the following advantages:

[0013] In the technical solution disclosed in this utility model, by using the cooperation of the feeding box, the feeding hood and the stirring assembly, the processing personnel can transport the plastic material into the inside of the feeding box through the feeding hood. Then, the personnel can turn on the power of the drive motor, so that its T-shaped rod drives the connecting rod to rotate continuously, so that the connecting rod quickly stirs the material on the inner wall of the feeding box, thereby dynamically feeding the material and preventing the feeding blockage from occurring.

[0014] A collection box is fixedly connected to the center of the front of the feeding box as described in this utility model. A dust pump is fixedly installed in the center of the top surface of the collection box. A dust suction pipe is inserted into the output end of the dust pump. One end of the dust suction pipe is inserted into the inside of the fixed frame. During the feeding process, the personnel can turn on the power of the dust pump, and then the dust suction pipe can deliver suction to the inside of the fixed frame. Then the dust inside the feeding box is collected along the filter screen, thus facilitating the unified collection and vacuuming of dust by personnel. Attached Figure Description

[0021] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0022] Figures 1-4 In one embodiment of this utility model, a feeding mechanism for a plastic extruder includes a feeding box 1. A fixed frame 2 is fixedly installed on the top of the feeding box 1. A feeding hood 3 is provided on the top of the fixed frame 2. The feeding hood 3 facilitates the effective protection of personnel during material conveying. Connecting rods 4 are fixedly connected to both sides of the outer surface of the feeding hood 3. A fixing plate 6 is fixedly installed on the top of the connecting rods 4. The connecting rods 4 and the fixing plate 6 facilitate the fixation of the drive motor 71 by personnel. A stirring assembly 7 is provided in the middle of the top surface of the fixing plate 6.

[0023] The specific problem addressed in this embodiment is the difficulty for personnel to prevent blockages inside the feeding equipment during the material feeding process, leading to low material feeding efficiency and affecting subsequent processing. This invention utilizes the coordinated use of the feeding box 1, the feeding hood 3, and the stirring assembly 7. Processing personnel can convey plastic materials through the feeding hood 3 into the feeding box 1. Then, the personnel can connect the power to the drive motor 71, causing its T-shaped rod 72 to continuously rotate the connecting rod 73. This allows the connecting rod 73 to rapidly stir the materials on the inner wall of the feeding box 1, thereby dynamically feeding the materials and preventing blockages.

[0024] The mixing assembly 7 includes a drive motor 71 fixedly connected to the top of the fixed plate 6. A T-shaped rod 72 is fixedly installed at the output end of the drive motor 71. Connecting rods 73 are fixedly connected to both sides of the bottom of the T-shaped rod 72. In this specific embodiment, a collection box 8 is fixedly connected to the center of the front of the feeding box 1. A dust pump 9 is fixedly installed at the center of the top surface of the collection box 8. A dust suction pipe 10 is inserted into the output end of the dust pump 9. One end of the dust suction pipe 10 is inserted into the inside of the fixed frame 2. During the feeding process, the personnel can turn on the power of the dust pump 9, and then the dust suction pipe 10 can deliver suction to the inside of the fixed frame 2. Then the dust inside the feeding box 1 is collected along the filter screen, which facilitates the unified collection and dust suction by personnel.

[0025] In this specific embodiment, the inner wall of the fixed frame 2 has a cavity, and a filter screen is embedded on the surface of the cavity. The filter screen facilitates the collection and filtration of dust. The aperture size of the filter screen is smaller than the diameter of ordinary plastic granules. A discharge pipe 11 is inserted into the middle of the bottom surface of the feeding box 1. A valve is provided on one side of the discharge pipe 11. With the discharge pipe 11 and the valve, when personnel need to discharge material from the feeding box 1, they can open the valve to open the discharge pipe 11, thereby facilitating quick material discharge and loading. Support legs 12 are fixedly installed on both sides of the bottom of the feeding box 1. The support legs 12 increase the stability of the feeding box 1. A transparent baffle 13 is provided on one side of the feeding box 1. The transparent baffle 13 facilitates personnel to observe changes in the internal conditions of the feeding box 1.

[0026] Working principle: When personnel are feeding materials such as plastic granules, the materials can be conveyed through the feeding hood 3 to the inside of the fixed frame 2 and the feeding box 1. Then, the personnel can turn on the power of the drive motor 71, which drives the T-shaped rod 72 to rotate. Subsequently, the T-shaped rod 72 drives the connecting rod 73 to rotate rapidly inside the feeding box 1. The connecting rod 73 then quickly stirs the materials inside the feeding box 1. At the same time, during the stirring process, the personnel can turn on the power of the dust pump 9, which delivers suction to the inside of the dust suction pipe 10. The dust suction pipe 10 then delivers suction to the inside of the fixed frame 2. The filter screen can then absorb the dust inside the feeding box 1 and convey it to the inside of the collection box 8. Finally, the personnel can turn the valve to open the discharge pipe 11, thus facilitating rapid material loading.

The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
