Description

Technical Field

[0001] The invention relates to the technical field of granulation production line equipment, and in particular to a double-medium granulation production line equipment for large pieces of carbon-based stone plastic box board scraps without crushing. Background Art

[0002] Carbon-based plastic is a composite material that combines the high strength of carbon fiber or carbon nanomaterials with the processing convenience of plastics (such as polypropylene PP, polyethylene PE, etc.). This type of material uses a special process to evenly distribute carbon-based reinforcement materials in the plastic matrix to form a plate with the characteristics of light weight, high strength, corrosion resistance, and aging resistance.

[0003] In the production process of carbon-based stone plastic boxes, it is necessary to cut and splice the carbon-based stone plastic box boards, and there will be a lot of scraps after cutting. In order to reduce resource waste, the carbon-based stone plastic box board large scraps can be used. The double-medium granulation production line without crushing can be used to directly process large scraps into particles through the crushing-free technology, simplifying the production process and improving resource utilization. This production line usually includes multiple links such as material transportation, heating and melting, filtration and purification, extrusion molding and cooling and pelletizing, and can use special mixed media or processes in the granulation process to improve product quality and production efficiency. In order to ensure the extrusion effect of the extrusion equipment on the production line, it is necessary to control the temperature of the discharge port of the extrusion equipment to avoid problems such as excessive temperature causing thermal decomposition of the material or becoming too viscous, making it difficult to cool and shape smoothly. It is also necessary to avoid problems such as premature hardening of the material due to excessively low temperature, making it difficult to fully fill the mold, making the product size unstable or rough, or even difficult to extrude. The existing extruder usually only has a heating rod for maintaining the temperature in the tank body, and the temperature control effect of the discharge port is poor. It is easy to have a discharge port temperature that is too high or too low, resulting in poor extrusion effect.

[0036] Example 1

[0037] A carbon-based stone plastic box board large scraps without crushing double medium granulation production line equipment, such as Figure 1-Figure 7 As shown, it includes an extruder 101, a single-axis motor 102, a first connecting block 103, a second connecting block 104, a first screw 105, a fan 106, a discharge pipe 108, a fixed pipe 109, a rotating pipe 110, a heating rod 113 and a regulating mechanism. The single-axis motor 102 is fixedly connected to the right side of the extruder 101, and the first connecting block 103 is slidably connected to the left output end of the single-axis motor 102. The first screw 105 is rotatably connected inside the extruder 101, and the second connecting block 104 is fixedly connected to the right side of the first screw 105. The first connecting block 113 is connected to the first screw 105. 03 is engaged with the second connecting block 104, a fan 106 is fixedly connected to the left side of the lower part of the extruder 101, a discharge pipe 108 is connected and fixedly connected to the left side of the extruder 101, a fixed pipe 109 is fixedly connected to the outside of the discharge pipe 108, a rotating pipe 110 is rotatably connected to the outside of the fixed pipe 109, the rotating pipe 110 is rotatably connected to the extruder 101, the fan 106 and the rotating pipe 110 are connected through the pipeline on the left side of the fan 106, heating rods 113 equidistantly distributed around the circumference are fixedly connected to the inside of the discharge pipe 108, and a regulating mechanism is provided on the extruder 101.

[0038] like Figure 3 and Figure 4 As shown, the first connection block 103 and the second connection block 104 are both provided with inclined surfaces on their sides close to each other.

[0039] like Figure 6As shown, the right side of the fixed pipe 109 is provided with connecting grooves which are evenly spaced around the circumference, and the left side of the fixed pipe 109 is provided with ventilation openings which are evenly spaced around the circumference, and the ventilation openings are directly opposite to the connecting grooves.

[0040] like Figure 3-Figure 5 As shown, the regulating mechanism for controlling the rotation of the rotating tube 110 includes a dual-axis motor 107, a first full gear 111, a second full gear 112 and a temperature sensor 114. The dual-axis motor 107 is fixedly connected to the left front side of the extruder 101, and the output end of the left side of the dual-axis motor 107 is fixedly connected to the second full gear 112. The right side of the rotating tube 110 is fixedly connected to the first full gear 111, and the first full gear 111 and the second full gear 112 are meshed with each other. A temperature sensor 114 is fixedly connected to the top left side of the extruder 101, and the temperature sensor 114 is electrically connected to the dual-axis motor 107, the temperature sensor 114 is electrically connected to the heating rod 113, and the temperature sensor 114 is electrically connected to the fan 106.

[0041] When people need to extrude and shape the molten carbon-based stone plastic, they can first pour the material into the feed hopper at the top right side of the extruder 101, then start the single-axis motor 102 and drive the first connecting block 103 to start rotating. At this time, since the first connecting block 103 is meshed with the second connecting block 104, the rotation of the first connecting block 103 will drive the second connecting block 104 and the first screw 105 to rotate, thereby transporting the material in the extruder 101 to the left to the discharge pipe 108 and extruding the material. During this period, it is necessary to start the heating rod 113 to keep the carbon-based stone plastic in a molten state as much as possible. When the temperature sensor 114 detects that the temperature of the left part of the extruder 101 and the discharge pipe 108 is too high, it will control The controller reduces the heating power of the heating rod 113, and starts the fan 106 and the double-axis motor 107 through the controller. The double-axis motor 107 drives the second full gear 112 to rotate clockwise by a certain angle. Since the first full gear 111 and the second full gear 112 are meshed, the first full gear 111 and the rotating tube 110 are rotated counterclockwise by a certain angle, so that the air outlet on the side of the rotating tube 110 and the air outlet on the side of the fixed tube 109 completely overlap. At this time, the fan 106 inhales external air and allows it to enter the rotating tube 110 through the pipeline, and then passes through the connecting groove on the right side of the fixed tube 109 until it contacts the outside of the discharge tube 108, thereby absorbing the discharge tube 108 and the material. The heat of the material is released by the temperature sensor 114, and then most of the gas will be quickly discharged from the air outlets of the rotating tube 110 and the fixed tube 109, and a small part of the gas will be discharged from the vent on the left side of the fixed tube 109, so that the discharge tube 108 can be cooled quickly to avoid overheating of the material and difficulty in cooling and shaping smoothly after extrusion. When the temperature sensor 114 detects that the temperature of the left part of the extruder 101 and the discharge tube 108 is too low, the heating power of the heating rod 113 will be increased through the controller, and the dual-axis motor 107 will be started through the controller. At this time, the dual-axis motor 107 will drive the second full gear 112 to rotate counterclockwise by a certain angle, thereby driving the first full gear 111 and the rotating tube 110 to rotate clockwise by a certain angle, and the rotating The clockwise rotation of the rotating tube 110 will completely intersect the air outlets on the side of the rotating tube 110 and the air outlets on the side of the fixed tube 109, thereby forming a relatively closed space between the discharge tube 108, the fixed tube 109 and the rotating tube 110 to reduce the escape of hot air and heat, so that the discharge tube 108 can be heated and insulated to avoid overcooling of the material and premature hardening, which makes the extruded product unstable in size or rough in surface. When the temperature is normal, the temperature sensor 114 will restore the normal power of the heating rod 113 through the controller, and will also cause the dual-axis motor 107 to drive the second full gear 112, the first full gear 111 and the rotating tube 110 to rotate in the opposite direction by a certain angle and return to their original state.

[0042] Example 2

[0043] On the basis of Example 1, Figure 8As shown, a blocking mechanism for blocking heat dissipation is also included. The blocking mechanism is arranged on the rotating tube 110. The blocking mechanism includes a fixing ring 201 and a connecting bolt 202. The two connecting bolts 202 are respectively fixed to the upper and lower sides of the rotating tube 110. A fixing ring 201 is fixed between the left parts of the upper and lower connecting bolts 202. The fixing ring 201 is in contact with the fixed tube 109.

[0044] When the temperature of the discharge pipe 108 is high, the dual-axis motor 107 drives the first full gear 111 and the rotating tube 110 to rotate counterclockwise by a certain angle through the second full gear 112, and the fixed ring 201 and the connecting bolt 202 will also be driven to rotate counterclockwise by a certain angle. The counterclockwise rotation of the fixed ring 201 by a certain angle will completely expose the vent on the left side of the fixed tube 109. At this time, a small part of the gas blown out by the fan 106 will be discharged from the vent on the left side of the fixed tube 109, thereby accelerating air circulation and increasing heat dissipation efficiency. When the temperature of the discharge pipe 108 is low, the dual-axis motor 107 drives the first full gear 111, the rotating tube 110, the fixed ring 201 and the connecting bolt 202 to rotate clockwise by a certain angle through the second full gear 112, the fixed ring 201 will completely block the vent on the left side of the fixed tube 109 to increase the sealing of the relatively closed space composed of the discharge pipe 108, the fixed tube 109 and the rotating tube 110, thereby further reducing the escape of hot air and heat and improving the insulation effect.

[0045] like Fig. 9 and Fig.10 As shown, it also includes a guiding mechanism for guiding the airflow, which is arranged on the fixed ring 201. The guiding mechanism includes an air guide block 301 and an air guide groove 302. The middle part of the fixed ring 201 is fixed with air guide blocks 301 equidistantly distributed around the circumference, and the air guide groove 302 is opened inside the air guide block 301. The air guide groove 302 is connected to the vent on the left side of the fixed tube 109.

[0046] like Fig. 9 As shown, the air outlet of the air guide groove 302 is directly opposite to the outlet on the left side of the outlet pipe 108.

[0047] When the temperature of the discharge pipe 108 is high, the fixed ring 201 rotates counterclockwise by a certain angle to fully expose the vent on the left side of the fixed pipe 109, and the air guide block 301 is also rotated counterclockwise by a certain angle, so that the air guide groove 302 of the air guide block 301 is connected with the vent on the left side of the fixed pipe 109 and is completely aligned. At this time, a small part of the gas blown out by the fan 106 will enter the air guide block 301 from the vent on the left side of the fixed pipe 109, and blow toward the material just extruded under the guidance of the air guide groove 302, so that the air can be guided to cool down the material just extruded, thereby accelerating the cooling and shaping of the material and improving product quality.

[0048] like Fig.11 and Fig.12As shown, it also includes a disconnection mechanism for separating the first connecting block 103 and the second connecting block 104. The disconnection mechanism is arranged on the dual-axis motor 107. The disconnection mechanism includes a connecting shaft 401, a second screw rod 402, a telescopic rod 403, a sliding frame 404 and a connecting plate 405. The connecting shaft 401 is fixedly connected to the output end on the right side of the dual-axis motor 107 through a coupling. The connecting shaft 401 is rotatably connected to the extruder 101. The right end of the connecting shaft 401 is fixedly connected to the second screw rod 402. The middle part of the second screw rod 402 is threadedly connected to the connecting plate 405. The telescopic rod 403 is fixedly connected to the upper and lower sides of the connecting plate 405. The sliding frame 404 is fixedly connected to the front side of the first connecting block 103. The sliding frame 404 is fixedly connected to the telescopic ends of the upper and lower telescopic rods 403. The sliding frame 404 is slidably connected to the second screw 402.

[0049] When the temperature of the discharge pipe 108 is low and the dual-axis motor 107 drives the second full gear 112 to rotate counterclockwise, the output end on the right side of the dual-axis motor 107 will also drive the connecting shaft 401 and the second screw 402 to rotate counterclockwise, and the counterclockwise rotation of the second screw 402 will cause the connecting plate 405, the telescopic rod 403, the sliding frame 404 and the first connecting block 103 to move to the right, until the first connecting block 103 moves to the right and separates from the second connecting block 104. At this time, the single-axis motor 102 can no longer drive the first screw 105 to rotate and extrude the material, thereby avoiding the extrusion of products with unstable dimensions and rough surfaces when the temperature is too low, and also avoiding forced extrusion and lifting. The previously hardened material causes damage to the equipment. When the temperature of the discharge pipe 108 is high, the dual-axis motor 107 drives the connecting shaft 401 and the second screw 402 to rotate clockwise. Since the sliding frame 404 and the first connecting block 103 are restricted and cannot move to the left, the clockwise rotation of the second screw 402 will only drive the connecting plate 405 to move to the left and stretch the telescopic rod 403. After the temperature returns to normal, the dual-axis motor 107 will drive the connecting shaft 401 and the second screw 402 to rotate in the opposite direction to restore to the original state, and the sliding frame 404, the connecting plate 405 and the first connecting block 103 will also move in the opposite direction to reset, and the telescopic rod 403 will also restore its initial telescopic state.

[0050] like Fig.13 As shown, air guide plates 501 are also included, and the outside of the discharge pipe 108 is fixedly connected with air guide plates 501 distributed in a circumference.

[0051] like Fig.13 As shown, the air guide sheet 501 is made of metal copper.

[0052] When the temperature of the discharge pipe 108 is high, the fan 106 allows external air to enter the rotating tube 110 through the pipe, and then pass through the connecting groove on the right side of the fixed tube 109 until it contacts the discharge pipe 108 and the air guide plate 501. The copper air guide plate 501 can quickly absorb the heat of the discharge pipe 108 and transfer it to the air, thereby accelerating the heat dissipation process. It can also guide the airflow so that the air can flow through the discharge pipe 108 more evenly, accelerate air circulation, and improve heat dissipation efficiency.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
