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.

DETAILED DESCRIPTION

[0035] Although the present invention may be described with respect to a particular application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those of ordinary skill in the art will recognize that terms such as above, below, upward, downward, etc. are used to describe the drawings and do not represent limitations on the scope of the present invention as defined by the appended claims. Any numerical designations such as first or second are merely exemplary and are not intended to limit the scope of the present invention in any way.

[0036] Example 1

[0037] A carbon-based stone plastic box board large scraps without crushing double medium granulation production line equipment, such as Figures 1-7 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 connecting block 103 and the second connecting block 104 are both provided with inclined surfaces on their sides close to each other.

[0039] like Figure 6As shown, a communication groove is provided on the right side of the fixed pipe 109 at equal circumferential intervals, and ventilation openings are provided on the left side of the fixed pipe 109 at equal circumferential intervals, and the ventilation openings are opposite to the communication groove.

[0040] As Figures 3-5 As shown, the control mechanism for controlling the rotation of the rotating pipe 110 includes a biaxial motor 107, a first full gear 111, a second full gear 112 and a temperature sensor 114. The biaxial motor 107 is fixedly connected to the left front part of the extruder 101. The output end on the left side of the biaxial motor 107 is fixedly connected to the second full gear 112. The rotating pipe 110 is fixedly connected to the first full gear 111 on the right side. The first full gear 111 and the second full gear 112 are meshed with each other. The temperature sensor 114 is fixedly connected to the top left of the extruder 101. The temperature sensor 114 is electrically connected to the biaxial 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, the material can be first poured into the feed hopper at the right top of the extruder 101, and then the single-axis motor 102 is started to drive the first connecting block 103 to start rotating. At this time, since the first connecting block 103 meshes 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, so as to convey the material in the extruder 101 to the left to the discharge pipe 108 and extrude the material. During this period, the heating rod 113 needs to be started 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, the heating rod 113 will be made to reduce the heating power through the controller, and the fan 106 and the double-axis motor 107 will be started through the controller. The double-axis motor 107 will drive the second full gear 112 to rotate clockwise by a certain angle. Since the first full gear 111 and the second full gear 112 mesh, the first full gear 111 and the rotating pipe 110 will be driven to rotate counterclockwise by a certain angle, so that the air outlet on the side of the rotating pipe 110 and the air outlet on the side of the fixed pipe 109 completely coincide. At this time, the fan 106 will inhale external air and make it enter the rotating pipe 110 through the pipeline, and then pass through the communication slot on the right side of the fixed pipe 109 until it contacts the outside of the discharge pipe 108, so as to absorb part of the heat of the discharge pipe 108 and the material. After that, most of the gas will quickly discharge from the air outlets of the rotating pipe 110 and the fixed pipe 109, and a small part of the gas will discharge from the ventilation port on the left side of the fixed pipe 109, so that the discharge pipe 108 can be quickly cooled, avoiding overheating of the material and making it difficult to cool and shape smoothly after extrusion. When the temperature sensor 114 detects that the temperature of the left part of the extruder 101 and the discharge pipe 108 is too low, the heating rod 113 will be made to increase the heating power through the controller, and the double-axis motor 107 will be started through the controller. At this time, the double-axis motor 107 will drive the second full gear 112 to rotate counterclockwise by a certain angle, so as to drive the first full gear 111 and the rotating pipe 110 to rotate clockwise by a certain angle. The clockwise rotation of the rotating pipe 110 will make the air outlet on the side of the rotating pipe 110 and the air outlet on the side of the fixed pipe 109 completely staggered, so as to form a relatively closed space between the discharge pipe 108, the fixed pipe 109 and the rotating pipe 110 to reduce the escape of hot air and heat. In this way, the discharge pipe 108 can be heated and insulated, avoiding the material being too cold and premature hardening, so that the size of the extruded product is unstable or the surface is rough. When the temperature is normal, the temperature sensor 114 will make the heating rod 113 restore the normal power through the controller, and will also make the double-axis motor 107 drive the second full gear 112, the first full gear 111 and the rotating pipe 110 to rotate reversely by a certain angle and return to the original state.

[0042] Embodiment 2

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

[0044] When the temperature of the discharge pipe 108 is relatively high, when the double-shaft motor 107 drives the first all-gear 111 and the rotating tube 110 to rotate counterclockwise by a certain angle through the second all-gear 112, the fixed ring 201 and the connecting bolts 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 ventilation opening on the left side of the fixed tube 109. At this time, a small part of the gas blown by the fan 106 will be discharged from the ventilation opening on the left side of the fixed tube 109, so as to accelerate air circulation and increase the heat dissipation efficiency. When the temperature of the discharge pipe 108 is relatively low, when the double-shaft motor 107 drives the first all-gear 111, the rotating tube 110, the fixed ring 201 and the connecting bolts 202 to rotate clockwise by a certain angle through the second all-gear 112, the fixed ring 201 will completely block the ventilation opening on the left side of the fixed tube 109, so as to increase the sealing performance of the relatively enclosed 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 heat preservation effect.

[0045] As Figure 9 and Figure 10 As shown, it further includes a guiding mechanism for guiding air flow. The guiding mechanism is arranged on the fixed ring 201. The guiding mechanism includes a gas guiding block 301 and a gas guiding groove 302. The middle part of the fixed ring 201 is fixedly connected with gas guiding blocks 301 distributed equidistantly in a circumferential manner. A gas guiding groove 302 is arranged inside the gas guiding block 301. The gas guiding groove 302 is communicated with the ventilation opening on the left side of the fixed tube 109.

[0046] As Figure 9 As shown, the air outlet of the gas guiding groove 302 is directly opposite to the discharge port on the left side of the discharge pipe 108.

[0047] When the temperature of the discharge pipe 108 is relatively high and the fixed ring 201 rotates counterclockwise by a certain angle and completely exposes the ventilation opening on the left side of the fixed tube 109, the gas guiding block 301 will also be driven to rotate counterclockwise by a certain angle, so that the gas guiding groove 302 of the gas guiding block 301 is communicated with and completely aligned with the ventilation opening on the left side of the fixed tube 109. At this time, a small part of the gas blown by the fan 106 will enter the gas guiding block 301 from the ventilation opening on the left side of the fixed tube 109 and be blown towards the just extruded material under the guidance of the gas guiding groove 302, so as to guide the air to cool the just extruded material, thereby accelerating the cooling and shaping of the material and improving the product quality.

[0048] As Figure 11 and Figure 12As shown in the figure, it further includes a disconnection mechanism for separating the first connection block 103 and the second connection block 104. The disconnection mechanism is arranged on the double-shaft motor 107. The disconnection mechanism includes a connection shaft 401, a second screw 402, a telescopic rod 403, a sliding frame 404 and a connecting plate 405. The connection shaft 401 is fixedly connected to the output end on the right side of the double-shaft motor 107 through a coupling. The connection shaft 401 is rotationally connected to the extruder 101. The right end of the connection shaft 401 is fixedly connected with a second screw 402. The middle part of the second screw 402 is threadedly connected with a connecting plate 405. Telescopic rods 403 are fixedly connected to both the upper and lower sides of the connecting plate 405. A sliding frame 404 is fixedly connected to the front side of the first connection block 103. The sliding frame 404 is fixedly connected to the telescopic ends of the upper and lower two 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 relatively low and the double-shaft motor 107 drives the second full gear 112 to rotate counterclockwise, the output end on the right side of the double-shaft motor 107 will also drive the connection shaft 401 and the second screw 402 to rotate counterclockwise. 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 connection block 103 to move to the right until the first connection block 103 moves to the right and separates from the second connection block 104. At this time, the single-shaft motor 102 can no longer drive the first screw 105 to rotate and extrude the material, thus avoiding the extrusion of products with unstable dimensions and rough surfaces when the temperature is too low, and also avoiding the damage of the equipment caused by forcibly extruding prematurely hardened materials. When the temperature of the discharge pipe 108 is relatively high and the double-shaft motor 107 drives the connection shaft 401 and the second screw 402 to rotate clockwise, since the sliding frame 404 and the first connection block 103 are restricted from moving 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 double-shaft motor 107 will drive the connection shaft 401 and the second screw 402 to rotate in the reverse direction to restore the original state, and the sliding frame 404, the connecting plate 405 and the first connection block 103 will also move in the reverse direction to reset, and the telescopic rod 403 will also restore the initial telescopic state.

[0050] As Figure 13 shown in the figure, it further includes air guide vanes 501. The air guide vanes 501 are fixedly connected to the outside of the discharge pipe 108 in a circumferential distribution.

[0051] As Figure 13 shown in the figure, the air guide vanes 501 are made of metal copper.

[0052] When the temperature of the discharge pipe 108 is relatively high, the blower 106 allows external air to enter the rotating pipe 110 through the pipeline, and then passes through the communication slot on the right side of the fixed pipe 109 until it contacts the discharge pipe 108 and the air guide piece 501. The copper air guide piece 501 can quickly absorb the heat of the discharge pipe 108 and transfer it to the air, accelerating the heat dissipation process. It can also guide the air flow, enabling the air to flow more evenly through the discharge pipe 108, accelerating the air circulation, and improving the heat dissipation efficiency.

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