[0001] The invention relates to the technical field of extruder equipment, in particular to an extruder for producing polyvinyl chloride cable materials with uniform heating. Background Art

[0002] Polyvinyl chloride is a common plastic material, widely used in the manufacture of pipes, wire insulation, clothing, flooring, packaging materials, etc. It has good weather resistance and corrosion resistance, so it is widely used in the fields of construction, medical, electronics, automobiles, etc. The single-screw extruder has developed from the original basic spiral structure to various structural types such as damping screw block, exhaust screw, slotted screw barrel, pin barrel, building block structure, etc. At the same time, due to the small space occupied by the single-screw extruder, it has become the main equipment used in the field of composite processing and plastic blown film.

[0003] Among them, in the process of heating the cable material, it is necessary to open the feed port and continuously put a large amount of material into the equipment. At this time, the hot air inside the equipment will escape outward through the feed port, causing the air temperature inside the equipment to drop, and the external heater can only heat the outer shell, resulting in different stability inside the equipment and uneven heating of the material. In view of the above problems, the following solutions are proposed. Summary of the invention

The invention utilizes the self-rotation of the threaded rod inside the extruder, and a control mechanism is arranged inside the equipment. Before using the equipment, the corresponding material is placed inside the corresponding inclined feeding plate, and the power supply of the power motor is turned on. The power motor drives the threaded feeding process through the rotating column, and the threaded fan blades rotate during the process. During the processing, it will contact the surface of the limit turn plate, and the limit turn plate cannot rotate due to the restriction of the sliding block. At this time, the threaded fan blade drives the sliding baffle to move along the material blocking chute through the limit turn plate, so that the sliding baffle is away from the bottom of the material pipe, and the material inside the material pipe falls into the processing shell.

Through the application of the above-mentioned components, when the equipment is feeding, the stirring frame will stir the material inside the material pipe to avoid material accumulation and prevent pipeline blockage.

[0014] The present invention has the following beneficial effects:

[0015] (1) The present invention utilizes the self-rotation of the threaded rod in the extruder and is provided with a control mechanism inside the device. Before using the device, the corresponding material is placed inside the corresponding inclined feed plate and the power supply of the power motor is turned on. The power motor drives the threaded feeding process through the rotating column. During the rotation, the threaded fan blades will contact the surface of the limit turn plate, and the limit turn plate cannot rotate due to the restriction of the sliding block. At this time, the threaded fan blades drive the sliding baffle plate to move along the material blocking chute through the limit turn plate, so that the sliding baffle plate is away from the bottom of the material pipe, and the material inside the material pipe falls into the processing shell. By utilizing the different contact positions of the threaded fan blades and several limit turn plates, the threaded fan blades can control the material inside the material pipe to enter the processing shell in batches, thereby reducing the probability of high-temperature gas escaping out through the feed port and the phenomenon of uneven heating of the internal material during the conventional feeding process.

[0016] (2) The present invention utilizes the characteristic that the sliding baffle is displaced by the threaded fan blades, and a sliding baffle is arranged inside the equipment. When the sliding baffle moves to the lowest part along the inner wall of the material blocking chute, the control push rod will enter the through hole at the bottom of the sliding baffle and push the prying plate to rotate. One end of the prying plate moves upward, and the other end drives the push rod to move downward. The push rod drives the sliding baffle to move downward along the chute, so that the sliding baffle releases the restriction on the limit rotating plate. The limit rotating plate rotates and enters the empty groove at the bottom of the sliding baffle. The threaded fan blades will no longer drive the sliding baffle to displace. At this time, the sliding baffle is reset under the push of the push spring 2. In addition, the staff can control the material ratio by adjusting the diameter of the leakage hole and controlling the speed of the reset of the push spring 2, so as to ensure that the ratio between the materials meets the requirements each time the filling is performed, reduce the number of manual fillings, and reduce the probability of high-temperature gas escaping out through the feed inlet.

[0017] (3) The present invention utilizes the force of the sliding baffle being pushed by the push spring to reset along the inner wall of the sliding baffle. An arc-shaped gear rod and a gear column are arranged inside the device. When the sliding baffle is displaced, the push rod will drive the arc-shaped gear rod to displace synchronously. In this process, the arc-shaped gear rod drives the rotating frame to rotate through the gear column, and the rotating frame drives the stirring frame to rotate along the inner wall of the material pipe. Through the application of the above components, when the device is feeding, the stirring frame will stir the material inside the material pipe to avoid material accumulation and prevent pipeline blockage.

[0018] (4) When the present invention is performing the heating process, due to the restriction of the bottom slope of the sloped base, one end of the power motor will move downward, while the other end will slightly tilt upward by an arc, such as Figure 3As shown, when the material begins to melt due to the heat, the solution inside the processing shell is affected by the upturn of the equipment. The material will accumulate inside the processing shell first, and will continue to move forward only after the bottom space is filled with the rotation of the threaded blades. In this process, the material is turned over by the stirring of the threaded blades, so that the material on the top can fit the inner wall of the processing shell, ensuring that the material is heated evenly and avoiding that part of the material is not melted and sent out of the equipment by the threaded rod, affecting the production effect of the equipment.

The invention utilizes the self-rotation of the internal threaded rod of the extruder, and a control mechanism 2 is arranged inside the device. Before using the device, the corresponding material is placed inside the corresponding inclined feeding plate 302, and the power supply of the power motor 110 is turned on. The power motor 110 drives 1045 through the rotating column 104 to complete During the process of threaded feeding, the threaded fan blades 105 will contact the surface of the limit rotating plate 207 during rotation, and the limit rotating plate 207 cannot rotate due to the restriction of the sliding block 211. At this time, the threaded fan blades 105 drive the sliding baffle 201 to move along the material blocking chute 103 through the limit rotating plate 207, so that the sliding baffle 201 is away from the bottom of the material pipe 303, and the material inside the material pipe 303 falls into the processing shell 101. By utilizing the different contact positions of the threaded fan blades 105 and several limit rotating plates 207, the threaded fan blades 105 can control the material inside the material pipe 303 to enter the processing shell 101 in batches, thereby reducing the probability of high-temperature gas escaping outward through the feed port during conventional feeding and the phenomenon of uneven heating of the internal material.

Taking advantage of the characteristic that the sliding baffle 201 is pushed and displaced by the threaded fan blades 105, a sliding block 211 is arranged inside the device. When the sliding baffle 201 moves to the lowest part along the inner wall of the material blocking groove 103, the control push rod 2 06 will enter the through hole at the bottom of the sliding baffle 201 and push the prying plate 209 to rotate, and one end of the prying plate 209 moves upward, and the other end drives the pushing rod 210 to move downward, and the pushing rod 210 drives the sliding block 211 to move downward along the sliding groove 212, so that the sliding block 211 releases the restriction on the limiting rotating plate 207, and the limiting rotating plate 207 rotates and enters the empty groove at the bottom of the sliding baffle 201.

When the sliding baffle 201 moves to the lowest part along the inner wall of the material blocking chute 103, the control push rod 206 will enter the through hole at the bottom of the sliding baffle 201 and push the prying plate 209 to rotate. One end of the prying plate 209 moves upward, and the other end drives the push rod 210 to move downward. The push rod 210 drives the sliding block 211 to move downward along the chute 212, so that the sliding block 211 releases the restriction on the limit rotating plate 207. The limit rotating plate 207 rotates and enters the empty groove at the bottom of the sliding baffle 201. The threaded blade 105 will no longer drive the sliding baffle 201 to displace. At this time, the sliding baffle 201 is reset under the push of the push spring 214. In addition, the staff can control the speed of the reset of the push spring 214 by adjusting the diameter of the leakage hole 204 to achieve control of the material ratio. The sliding baffle 201 is pushed by the push spring 214 to reset along the inner wall of the sliding baffle 201. An arc-shaped gear rod 307 and a gear column 306 are arranged inside the equipment. When the sliding baffle 201 is displaced, the push rod 210 will drive the arc-shaped gear rod 307 to displace synchronously. In this process, the arc-shaped gear rod 307 drives the rotating frame 305 to rotate through the gear column 306, and the rotating frame 305 drives the stirring frame 304 to rotate along the inner wall of the material pipe 303. Through the application of the above-mentioned components, when the equipment is feeding, the stirring frame 304 will stir the material inside the material pipe 303 to avoid material accumulation and prevent pipeline blockage.

[0044] During the heating process, restricted by the bottom slope of the sloped base 109, one end of the power motor 110 will move downward, while the other end will tilt upward slightly. Figure 3 As shown, when the material begins to melt due to the heat, the solution inside the processing shell 101 is affected by the upturning of the equipment, and the material will accumulate inside the processing shell 101 first, and with the rotation and transmission of the threaded blades 105, the material will not continue to move forward until it fills the space at the bottom. In this process, the material is turned over by the stirring of the threaded blades 105, so that the material at the top can fit against the inner wall of the processing shell 101, ensuring that the material is heated evenly, and preventing part of the material from being sent out of the equipment by the threaded rod before it melts, affecting the production effect of the equipment.
