Description

Technical Field

[0001] The invention relates to the technical field of nylon slice production devices, and in particular to a production device for ultra-low viscosity nylon slices. Background Art

[0002] Nylon chips are the intermediate products in the production process of nylon products. They are made by extruding nylon in a molten state from a mold with a round hole. The extrusion port of the mold is located in water, and the extruded molten nylon is quickly cooled and solidified by water. During extrusion, the cooled nylon is cut into small particles by a rotating tool. These granular nylon is 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 extruded from the mold. When the nylon in the extruder is completely discharged, the staff needs to take out the mold in time and immediately discharge the nylon that has not been completely cooled in the mold for cleaning. If the staff disassembles for too long or leaves for other reasons, the nylon that has not been completely cooled in the mold may solidify in the mold, which will make cleaning difficult, and the nylon solidified in the mold is very easy to damage the mold during cleaning, thereby causing damage to the mold.

DETAILED DESCRIPTION

[0018] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0019] In the production process of nylon slices, the molten nylon will first be continuously formed through the mold by an extruder. The molten nylon in the mold will not solidify in the mold. When the nylon in the extruder is completely discharged, the remaining nylon in the mold needs to be cleaned. At this time, the staff needs to take out the mold and immediately discharge the molten nylon in the mold. If the staff disassembles the mold for too long or leaves for other reasons, the molten nylon in the mold will solidify into the mold and be difficult to clean. In addition, the mold is easily damaged when cleaning the nylon solidified in the mold, causing damage to the mold.

Initially, the sliding plate 9 contacts the first fixed tube 8, and the first fixed tube 8 is connected with the hole on the sliding plate 9. The sliding plate 9 is sealed and limited in sliding connection with a sliding member 10. The sliding member 10 is composed of a circumferentially distributed round rod and a circular ring. The round rod passes through the fixed cover 701 and the sliding plate 9. The right end of the round rod is connected to the hole on the mold 7. Correspondingly, the round rod on the sliding member 10 is sealed and slidably matched with the hole on the mold 7. When the sliding member 10 moves to the right, the round rod on the sliding member 10 gradually enters the hole of the mold 7 to clean the nylon in the hole of the mold 7. The sliding member 10 is sealed and slidably connected to the fixed cover 701. The upper side of the first fixed shell 1 is fixedly connected to the electric telescopic rod 101. 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 provided on the first fixed tube 8, and the cleaning component is used to clean the mold 7.

[0021] Reference Figure 3-Figure 5 As shown, the cleaning component includes a second fixed pipe 11, which is fixedly connected to and communicated with the left side of the first fixed pipe 8. The second fixed pipe 11 is fixedly connected to and communicated with a first conduit 12. The first conduit 12 is connected to an external water pump. After the water pump is started, the water pump passes hot water into the first conduit 12. A first connecting pipe 13 is fixedly connected and communicated between the first conduit 12 and the first fixed pipe 8. The first connecting pipe 13 is located on the left side of the second fixed pipe 11. An electric switch valve is arranged in the first connecting pipe 13. An electric valve 14 is arranged on the left side of the first fixed pipe 8. The lower end of the first connecting pipe 13 is located on the right side of the electric valve 14.

[0022] Reference Figure 3-Figure 5As shown, a reciprocating motor 21 is fixedly connected to the upper side of the second fixed tube 11, and a second rotating shaft 22 is rotatably connected to the upper side of the second fixed tube 11. The output shaft of the reciprocating motor 21 and the second rotating shaft 22 are driven by a worm gear.

The limiting member 25 is a hollow spherical structure.

[0023] When the device is used to produce nylon slices, the first fixed tube 8 is connected to the discharge port of the extruder. The extruder is an existing device and is not shown in the attached drawings. First, the extruder connected to the left side of the first fixed tube 8 is started. The extruder squeezes the molten nylon into the first fixed tube 8 and flows to the right along the first fixed tube 8. At the same time, the rotating motor 3 and the water pump under the first fixed shell 1 are started. The water pump under the first fixed shell 1 makes water flow from bottom to top in the first fixed shell 1. 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, and the fixed rod 5 drives the cutter 6 to rotate clockwise.

[0024] In the process of the molten nylon in the first fixed tube 8 moving to the right, the nylon enters between the mold 7 and the sliding plate 9 through the sliding plate 9, and then the nylon in the mold 7 gradually increases, and 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 with the water in the first fixed shell 1, and the nylon extruded from the mold 7 is cooled by the water. At the same time, the cutter 6 rotates to continuously cut off the nylon extruded from the mold 7 to form nylon slices. The nylon slices enter the drying barrel driven by the water flow of the first fixed shell 1, and the production of nylon slices is completed.

[0025] During the production process, if the nylon in the extruder is consumed, the nylon remaining in the mold 7 will gradually cool and condense. Once the nylon in the extruder is consumed, the staff will close the electric valve 14, then open the electric switch valve in the first connecting pipe 13, and start the water pump connected to the first conduit 12. The hot water enters the second fixed pipe 11 through the first connecting pipe 12, and 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 rinses the molten nylon in the first fixed pipe 8, and the remaining nylon in the first fixed pipe 8 and the remaining nylon in the mold 7 are discharged from the hole on the right side of the mold 7, so that the mold 7 and the first fixed pipe 8 are cleaned.

[0026] After cleaning the mold 7 and the first fixed tube 8 for a period of time, the reciprocating motor 21 is started, and the output shaft of the reciprocating motor 21 drives the second rotating shaft 22 to rotate through the worm gear. The worm gear cooperates with each other so that the reciprocating motor 21 can accurately control the rotation of the second rotating shaft 22 to prevent the second rotating shaft 22 from driving the output shaft of the reciprocating motor 21 to rotate through the transmission, and slipping occurs. The second rotating shaft 22 gradually releases the wire rope 23. At this time, since the first guide tube 12 continues to pass water into the second fixed tube 11, there is pressure in the second fixed tube 11. When the wire rope 23 is released, the water in the second fixed tube 11 squeezes the limit column 24 and the limit member 25 downward into the first fixed tube 8. When the limit column 24 and the limit member 25 are pressed downward, the limit column 24 and the limit member 25 are pressed downward. After the limit piece 25 enters the first fixed tube 8, the first fixed tube 8 is blocked. At this time, water squeezes the limit column 24 and the left side of the limit piece 25, so that the limit column 24 and the limit piece 25 gradually move to the right along the first fixed tube 8. During the movement of the limit piece 25, the inner wall of the first fixed tube 8 is cleaned for the second time. When the limit piece 25 moves to contact the sliding plate 9, the limit piece 25 is stuck on the sliding plate 9 and no longer moves. At this time, the wire rope 23 is released, and the limit column 24 gradually moves to the right in the limit piece 25. The limit column 24 enters the sliding plate 9, and the right side surface of the limit column 24 gradually moves to align with the right side surface of the sliding plate 9, and then the limit column 24 no longer moves relatively under the limitation of the limit piece 25.

[0027] When the limit column 24 no longer moves relative to the limit member 25, the wire rope 23 continues to be released, and the limit column 24 and the limit member 25 squeeze the sliding plate 9 to the right. In the process of releasing the wire rope 23, the electric telescopic rod 101 is started, and 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 squeezing of the limit column 24 and the limit member 25, so that the sliding plate 9 gradually separates from the first fixed pipe 8. After separation, the water in the first fixed pipe 8 enters When the sliding plate 9 is moved to between the sliding plate 9 and the fixed cover 701, the water squeezes the sliding plate 9 to move to the right, and the sliding member 10 always keeps in contact with the right end of the sliding plate 9. When the right side of the sliding plate 9 contacts the mold 7, the sliding member 10 continues to move, and 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 to prevent the mold 7 from being blocked. When the right side of the sliding member 10 is aligned with the mold 7, it stops. At this time, the first conduit 12, the water pump connected to the first conduit 12, the electric telescopic rod 101 and other started electrical components are turned off.

[0028] After use, the staff disassembles the mold 7 and the cutter 6, and drains the hot water remaining near the mold 7. After checking and maintaining the mold 7 and the cutter 6, they are reinstalled and the reciprocating motor 21 is started in reverse. The output shaft of the reciprocating motor 21 rotates in the opposite direction, and the second rotating shaft 22 is driven by the worm gear to reel in the wire rope 23, reset the limit column 24 and the limit member 25, open the electric valve 14, close the electric switch valve in the first connecting pipe 13, and start the electric telescopic rod 101 to reset the sliding member 10 for the next use.

[0029] After the nylon is extruded and cut, the formed nylon particles move directly upward under the drive of the water flow. Since the nylon particles have not been completely solidified at this time, adjacent nylon particles are easily contacted with each other just after being cut under the drive of the water flow, resulting in the accumulation of nylon particles. In severe cases, adhesion may occur, affecting the granulation effect.

[0030] Example 2: Based on Example 1, refer to Figure 6-Figure 8 As shown, a third fixed shell 31 is also included. The third fixed shell 31 is arranged on the right side of the mold 7. An arc hole is opened in the middle of the third fixed shell 31. The third fixed shell 31 is connected with an external water pipe. A hole corresponding to the hole on the mold 7 is opened on 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. The hole on the third fixed shell 31 is fixed with symmetrically distributed limit blocks 32. The symmetrically distributed limit blocks 32 are circumferentially distributed on the third fixed shell 31. The limit blocks 32 are arc-shaped. A circular tube column is fixed and connected to the right hole of the mold 7. The circular tube column on the right side of the mold 7 is in contact with two adjacent limit blocks 32.

[0031] Reference Figure 6-Figure 9 As shown, the second fixed shell 2 is fixedly connected and communicated with a second conduit 41, and the upper end of the second conduit 41 is connected with a water pipe. A cavity is arranged in the first rotating shaft 4, and a hole is opened on the right side of the first rotating shaft 4. The cavity on the first rotating shaft 4 is communicated with the second fixed shell 2 through the hole on the right side of the first rotating shaft 4. The fixed rod 5 is a hollow structure, and the fixed rod 5 is communicated with the cavity in the first rotating shaft 4. A cavity is opened on the right side of the tool 6, and the fixed rod 5 is communicated with the cavity of the tool 6. The fixed rod 5 and the tool 6 are sealed and slidably connected. A spring 42 is fixedly connected between the fixed rod 5 and the tool 6, and the spring 42 is used to drive the tool 6 to move to the left, so that the tool 6 approaches the third fixed shell 31. The cavity on the right side of the tool 6 is fixedly connected and communicated with a symmetrically distributed second connecting pipe 43, and a water outlet 44 is opened on the left side of the tool 6. When in use, the water discharged from the water outlet 44 is squeezed and located between the tool 6 and the third fixed shell 31, so that the tool 6 does not contact the third fixed shell 31, thereby reducing the wear of the tool 6.

[0032] During the process of molten nylon being extruded from the die 7, the staff introduces water into the third fixed shell 31, and the water is discharged from the holes on the third fixed shell 31. The water entering the third fixed shell 31 cools the right end of the die 7, thereby accelerating the cooling speed of the nylon discharged from the die 7. During the rotation of the cutter 6, after the cutter 6 cuts off the extruded nylon, the water in the third fixed shell 31 is discharged through the limit block 32, the adjacent holes in the third fixed shell 31 and the holes formed by the die 7. The discharged water guides the cut nylon to the right, and blocks the adjacent nylon that has just been cut by the water flow, thereby preventing the adjacent nylons below from contacting and sticking to each other with the adjacent nylons above under the influence of the water flow from bottom to top in the first fixed shell 1.

[0033] During the rotation of the cutter 6, the staff introduces continuous and stable water into the second conduit 41, the water in the second conduit 41 enters the first rotating shaft 4 through the second fixed shell 2, the water in the first rotating shaft 4 enters the cutter 6 through the fixed rod 5, and the water entering the cutter 6 is discharged from the water outlet 44 on the cutter 6 through the second connecting pipe 43. During the process of discharging water, the water outlet 44 on the cutter 6 squeezes the third fixed shell 31, and the cutter 6 moves to the right under the reaction force, so that a layer of water film exists between the cutter 6 and the third fixed shell 31, preventing the cutter 6 from directly contacting the third fixed shell 31 and reducing the wear of the cutter 6.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
