Description

Technical Field

[0001] The present invention relates to the technical field of nylon chip production devices, and particularly relates to a production device for ultra-low viscosity nylon chips. Background Art

[0002] Nylon chips are intermediate products in the production process of nylon products. The molten nylon is extruded from a mold with round holes, and the extrusion outlet of the mold is located in water. The extruded molten nylon is quickly cooled and solidified by water. While extruding, the cooled nylon is cut into small granular shapes by a rotating cutter. These granular nylons are nylon chips. When in use, the nylon chips are melted again by a heating mechanism to manufacture various products. In the production process of nylon chips, the molten nylon is continuously extruded into the mold by an extruder and then extruded from the mold. When all the nylon in the extruder is discharged, the staff needs to promptly remove the mold and immediately discharge the nylon that has not been fully cooled in the mold for cleaning. If the disassembly time of the staff is too long or they leave for other reasons, the nylon that has not been fully cooled in the mold may solidify in the mold, which will make the cleaning difficult, and the nylon solidified in the mold is extremely easy to damage the mold during cleaning, thus causing damage to the mold.

Specific embodiments

[0026] The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0027] During the production process of nylon chips, the molten nylon will continuously pass through the mold through an extruder to form. The molten nylon in the mold will not solidify in the mold. When the nylon in the extruder is completely discharged, it is necessary to clean the residual nylon in the mold. At this time, the staff needs to take out the mold and immediately discharge the molten nylon in the mold. However, if the staff takes too long to disassemble or leaves for other reasons, the molten nylon in the mold will solidify in the mold, making it difficult to clean, and it is very easy to damage the mold when cleaning the nylon solidified in the mold, resulting in damage to the mold.

[0028] Example 1: A production device for ultra-low viscosity nylon chips, refer to Figures 1-5As shown in the figure, it includes a first fixed shell 1. The lower side of the first fixed shell 1 is connected to an external water pump, and the upper side of the first fixed shell 1 is connected to a drying cylinder. Water flows upward from the lower side of the first fixed shell 1 and drives the nylon chips cut inside the first fixed shell 1 to move upward into the drying cylinder to dry the nylon chips. The first fixed shell 1 is detachably connected to a second fixed shell 2. A rotating motor 3 is fixedly connected to the right side of the second fixed shell 2. The output shaft of the rotating motor 3 is fixedly connected to a first rotating shaft 4. The first rotating shaft 4 is located inside the second fixed shell 2. The first rotating shaft 4 is detachably connected to a fixing rod 5. A cutter 6 is fixedly connected to the fixing rod 5. The left side of the first fixed shell 1 is detachably connected to a mold 7. The right side of the mold 7 is provided with circumferentially distributed holes. The left side of the mold 7 is detachably connected to a fixing cover 701. A first fixed pipe 8 is fixedly connected to the middle of the fixing cover 701. The left side of the first fixed pipe 8 is connected to an extruder. A sliding plate 9 is hermetically slidably connected to the inside of the mold 7. The sliding plate 9 is in limit fit with the fixing cover 701. There is a hole in the middle of the sliding plate 9. Initially, the sliding plate 9 contacts the right side of the fixing cover 701 to limit the sliding of the sliding plate 9. The sliding plate 9 is in communication and cooperation with the first fixed pipe 8 through the hole in the middle. The sliding plate 9 is in communication and cooperation with the first fixed pipe 8. Initially, the sliding plate 9 contacts the first fixed pipe 8, and the first fixed pipe 8 is in communication with the hole on the sliding plate 9. A sliding member 10 is hermetically and slidably connected to the sliding plate 9. The sliding member 10 is composed of circumferentially distributed round rods and a ring. The round rods pass through the fixing cover 701 and the sliding plate 9. The right ends of the round rods correspond to the holes on the mold 7. The round rods on the sliding member 10 are in hermetic sliding fit with the holes on the mold 7. During the process of the sliding member 10 moving to the right, the round rods on the sliding member 10 gradually enter the holes in the mold 7 to clean the nylon in the holes of the mold 7. The sliding member 10 is hermetically slidably connected to the fixing cover 701. An electric telescopic rod 101 is fixedly connected to the upper side of the first fixed shell 1. The telescopic end of the electric telescopic rod 101 is fixedly connected to the sliding member 10 through a square plate. A cleaning component is arranged on the first fixed pipe 8, and the cleaning component is used to clean the mold 7.

[0029] Referring to Figures 3-5 As shown in the figure, the cleaning component includes a second fixed pipe 11. The second fixed pipe 11 is fixedly connected and communicated with the left side of the first fixed pipe 8. The second fixed pipe 11 is fixedly connected and communicated with a first conduit 12. The first conduit 12 is connected to an external water pump. After starting the water pump, the water pump passes hot water into the first conduit 12. A first communicating pipe 13 is fixedly connected and communicated between the first conduit 12 and the first fixed pipe 8. The first communicating pipe 13 is located on the left side of the second fixed pipe 11. An electric switch valve is arranged inside the first communicating pipe 13. An electric valve 14 is arranged on the left side of the first fixed pipe 8. The lower end of the first communicating pipe 13 is located on the right side of the electric valve 14.

[0030] Referring to Figures 3-5As shown in the figure, a reciprocating motor 21 is fixedly connected to the upper side of the second fixed pipe 11. A second rotating shaft 22 is rotatably connected to the upper side of the second fixed pipe 11. The output shaft of the reciprocating motor 21 and the second rotating shaft 22 are driven by a worm and worm gear. A steel wire rope 23 is wound around the second rotating shaft 22. The lower end of the steel wire rope 23 is fixedly connected with a limit post 24. The limit post 24 is hermetically and slidably connected with a limiting member 25. The limiting member 25 is hermetically and slidably connected with and limited to the second fixed pipe 11. The limiting member 25 is hermetically slidably connected with the first fixed pipe 8. The limiting member 25 and the limit post 24 are jointly hermetically connected with the hole in the middle of the sliding plate 9, and the limiting member 25 is limited to the sliding plate 9. The limit post 24 is limited to the limiting member 25. The limiting member 25 is a hollow spherical structure.

[0031] When using this device to produce nylon chips, the first fixed pipe 8 is communicated with the discharge port of the extruder. The extruder is an existing device and is not shown in the drawings. First, start the extruder connected to the left side of the first fixed pipe 8. The extruder extrudes the molten nylon into the first fixed pipe 8 and flows to the right along the first fixed pipe 8. At the same time, start the rotating motor 3 and the water pump below the first fixed shell 1. The water pump below the first fixed shell 1 makes the water flow upward in the first fixed shell 1 from bottom to top. The output shaft of the rotating motor 3 drives the first rotating shaft 4 to rotate clockwise. The first rotating shaft 4 drives the fixed rod 5 to rotate. The fixed rod 5 drives the cutter 6 to rotate clockwise.

[0032] During the process of the molten nylon moving to the right in the first fixed pipe 8, the nylon enters between the mold 7 and the sliding plate 9 through the sliding plate 9. Then the nylon in the mold 7 gradually increases. The nylon is discharged through the hole on the right side of the mold 7. After the nylon is discharged from the mold 7, it contacts the water in the first fixed shell 1. The nylon extruded from the mold 7 is cooled by the water. At the same time, the cutter 6 rotates and continuously cuts off the nylon extruded from the mold 7 to form nylon chips. The nylon chips enter the drying barrel under the drive of the water flow in the first fixed shell 1, completing the production of nylon chips.

[0033] During the production process, if the nylon in the extruder is consumed, the nylon remaining in the mold 7 will gradually cool and solidify. Once the nylon in the extruder is consumed, the staff closes the electric valve 14, then opens the electric switch valve in the first connecting pipe 13, and starts the water pump connected to the first conduit 12. The hot water enters the second fixed pipe 11 through the first conduit 12. The hot water entering the second fixed pipe 11 enters the first fixed pipe 8 through the first connecting pipe 13. The hot water squeezes and flushes the molten nylon in the first fixed pipe 8, discharging the remaining nylon in the first fixed pipe 8 and the remaining nylon in the mold 7 from the hole on the right side of the mold 7, cleaning the mold 7 and the first fixed pipe 8.

[0034] After cleaning the mold 7 and the first fixed pipe 8 for a period of time, start the reciprocating motor 21. The output shaft of the reciprocating motor 21 drives the second rotating shaft 22 to rotate through the worm and gear. By the mutual cooperation of the worm and gear, the reciprocating motor 21 can accurately control the rotation of the second rotating shaft 22, preventing the second rotating shaft 22 from driving the output shaft of the reciprocating motor 21 to rotate through transmission and causing slippage. The second rotating shaft 22 gradually releases the steel wire rope 23. At this time, since the first conduit 12 continuously feeds water into the second fixed pipe 11, there is pressure in the second fixed pipe 11. After the steel wire rope 23 is released, the water in the second fixed pipe 11 squeezes the limit post 24 and the limiting member 25 downward into the first fixed pipe 8. When the limit post 24 and the limiting member 25 enter the first fixed pipe 8, they block the first fixed pipe 8. At this time, the water squeezes the left side of the limit post 24 and the limiting member 25, causing the limit post 24 and the limiting member 25 to gradually move to the right along the first fixed pipe 8. During the movement of the limiting member 25, the inner wall of the first fixed pipe 8 is cleaned for the second time. When the limiting member 25 moves into contact with the sliding plate 9, the limiting member 25 is stuck on the sliding plate 9 and stops moving. At this time, the steel wire rope 23 is released, and the limit post 24 gradually moves to the right inside the limiting member 25. The limit post 24 enters the sliding plate 9, and the right side surface of the limit post 24 gradually moves to align with the right side surface of the sliding plate 9. Then, the limit post 24 stops moving relative to each other under the limitation of the limiting member 25.

[0035] When the limit post 24 stops moving relative to each other under the limitation of the limiting member 25, the steel wire rope 23 continues to be released. The limit post 24 and the limiting member 25 squeeze the sliding plate 9 to the right. During the process of releasing the steel wire rope 23, the electric telescopic rod 101 is started. The telescopic end of the electric telescopic rod 101 drives the sliding member 10 to move to the right. The sliding member 10 gradually releases the sliding plate 9. The sliding plate 9 moves to the right synchronously with the sliding member 10 under the extrusion of the limit post 24 and the limiting member 25, causing the sliding plate 9 to gradually separate from the first fixed pipe 8. After separation, the water in the first fixed pipe 8 enters between the sliding plate 9 and the fixed cover 701. At this time, the water squeezes the sliding plate 9 to move to the right. The sliding member 10 always remains in contact with the right end of the sliding plate 9. When the right side surface of the sliding plate 9 contacts the mold 7, the sliding member 10 continues to move. The round rod on the right side of the sliding member 10 gradually enters the hole of the mold 7 to clean the hole of the mold 7 and prevent the mold 7 from being blocked. When the right side surface of the sliding member 10 aligns with the mold 7, it stops. At this time, close the first conduit 12, the water pump connected to the first conduit 12, the electric telescopic rod 101, and other started electrical components.

[0036] After use, the staff disassemble the mold 7 and the cutting tool 6, and drain the remaining hot water near the mold 7. After inspecting and maintaining the mold 7 and the cutting tool 6, they are reinstalled, and the reciprocating motor 21 is started in reverse. The output shaft of the reciprocating motor 21 rotates in reverse, and through the transmission of the worm and worm gear, the second rotating shaft 22 winds up the steel wire rope 23, resets the limit post 24 and the limiting member 25, and opens the electric valve 14. The electric switch valve in the first communication pipe 13 is closed, and at the same time, the electric telescopic rod 101 is started to reset the sliding member 10, facilitating the next use.

[0037] After the nylon is extruded and cut off, the formed nylon particles move directly upward under the drive of the water flow. Since the nylon particles are not completely solidified at this time, adjacent nylon particles are easily in contact with each other just after being cut off under the drive of the water flow, resulting in the accumulation of nylon particles and even adhesion in severe cases, affecting the granulation effect.

[0038] Example 2: On the basis of Example 1, referring to Figures 6-8 As shown, it further includes a third fixed shell 31. The third fixed shell 31 is arranged on the right side of the mold 7. An arc-shaped hole is formed in the middle of the third fixed shell 31. The third fixed shell 31 is communicated with an external water pipe. A hole corresponding to the hole on the mold 7 is formed in the third fixed shell 31. The diameter of the hole on the third fixed shell 31 is larger than the diameter of the hole on the mold 7. Symmetrically distributed limiting blocks 32 are fixedly connected in the hole on the third fixed shell 31. The symmetrically distributed limiting blocks 32 are circumferentially distributed on the third fixed shell 31. The limiting blocks 32 are arc-shaped. A circular tube column is fixedly connected and communicated at the right-side hole of the mold 7. The circular tube column on the right side of the mold 7 is in contact and cooperation with two adjacent limiting blocks 32.

[0039] Referring to Figures 6-9 As shown, the second fixed shell 2 is fixedly connected and communicated with a second conduit 41. The upper end of the second conduit 41 is communicated with a water pipe. A cavity is arranged inside the first rotating shaft 4. A hole is formed on the right side of the first rotating shaft 4. The cavity on it is communicated with the second fixed shell 2 through the hole on the right side of the first rotating shaft 4. The fixing rod 5 is of a hollow structure. The fixing rod 5 is communicated with the cavity inside the first rotating shaft 4. A cavity is formed on the right side of the cutting tool 6. The fixing rod 5 is communicated with the cavity of the cutting tool 6. The fixing rod 5 is in sealed sliding connection with the cutting tool 6. A spring 42 is fixedly connected between the fixing rod 5 and the cutting tool 6. The spring 42 is used to drive the cutting tool 6 to move leftward, so that the cutting tool 6 approaches the third fixed shell 31. Symmetrically distributed second communication pipes 43 are fixedly connected and communicated with the cavity on the right side of the cutting tool 6. A water outlet 44 is formed on the left side of the cutting tool 6. During use, the water discharged from the water outlet 44 is squeezed between the cutting tool 6 and the third fixed shell 31, so that the cutting tool 6 is not in contact with the third fixed shell 31, reducing the wear of the cutting tool 6.

[0040] During the process of molten polyamide being extruded from the die 7, the staff inject water into the third fixed housing 31. The water discharges from the holes on the third fixed housing 31 and enters the third fixed housing 31. The water inside the third fixed housing 31 cools the right end of the die 7, accelerating the cooling rate of the polyamide discharged from the die 7. During the rotation of the cutter 6, after the cutter 6 cuts off the extruded polyamide, the water from inside the third fixed housing 31 discharges through the holes formed by the limit block 32, the adjacent holes inside the third fixed housing 31, and the die 7. The discharged water guides the cut polyamide to the right and hinders the just-cut and adjacent polyamide through the water flow, preventing the just-cut polyamide from contacting and adhering to each other under the drive of the upward water flow from bottom to top inside the first fixed housing 1 between the adjacent polyamide below and the adjacent polyamide above.

[0041] During the rotation of the cutter 6, the staff inject continuously stable water into the second conduit 41. The water inside the second conduit 41 enters the first rotating shaft 4 through the second fixed housing 2. The water inside the first rotating shaft 4 enters the cutter 6 through the fixed rod 5. The water entering the cutter 6 discharges from the water outlet 44 on the cutter 6 through the second communication pipe 43. When the water discharges from the water outlet 44 on the cutter 6, it squeezes the third fixed housing 31. Under the reaction force, the cutter 6 moves to the right, creating a water film between the cutter 6 and the third fixed housing 31 to prevent the direct contact between the cutter 6 and the third fixed housing 31 and reduce the wear of the cutter 6.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
