Description

Technical Field

[0001] This invention relates to the field of production technology, specifically to a nylon 6 modified chip production apparatus and production method. Background Technology

[0002] Nylon 6 has similar chemical and physical properties to Nylon 66; however, it has a lower melting point and a wider processing temperature range. Its impact resistance and solvent resistance are better than Nylon 66, but it is also more hygroscopic. Since many quality characteristics of molded parts are affected by hygroscopicity, this must be fully considered when designing products using Nylon 6. Various modifiers are often added to improve the mechanical properties of Nylon 6. Glass fiber is the most common additive, and sometimes synthetic rubbers such as EPDM and SBR are added to improve impact resistance. For products without additives, the shrinkage rate of Nylon 6 raw materials is between 1% and 1.5%. Adding glass fiber additives can reduce the shrinkage rate to 0.3% (but slightly higher in the direction perpendicular to the flow path). The shrinkage rate of the molding assembly is mainly affected by the material's crystallinity and hygroscopicity. The actual shrinkage rate is also a function of the molded part design, wall thickness, and other process parameters. Drying Nylon 6 injection molding is crucial because Nylon 6 readily absorbs moisture; therefore, special attention must be paid to drying before processing. If the material is supplied in waterproof packaging, the container should be kept sealed. If the humidity is greater than 0.2%, it is recommended to dry in hot air at a temperature above 80°C for 16 hours. If the material has been exposed to air for more than 8 hours, it is recommended to vacuum dry at 105°C for more than 8 hours.

[0003] For example, Chinese patent CN201921965191.X, entitled "A Device for Producing Nylon 6 Chips," discloses a device for producing nylon 6 chips, including a production chamber and a hydraulic column. The production chamber is located at the middle of its upper outer wall, and a first filter plate is installed inside. A rotating shaft is installed at the middle of the upper inner wall of the first filter plate, and a stirring blade is fixedly connected to the outer wall of the rotating shaft. The hydraulic column is installed at the middle of the lower outer wall of the first filter plate. A baffle is installed at the lower end of the left outer wall of the production chamber via a through-engagement mechanism, and a discharge port is installed at the lower end of the baffle. A drainage box is fixedly connected to the upper end of the right outer wall of the production chamber. This device for producing nylon 6 chips uses a lifting structure between the hydraulic column and the first filter plate. The lifting of the hydraulic column allows for adjustment of the height of the first filter plate as needed. Raising the plate during feeding reduces the damage caused by gravity, and the lifting structure accelerates the screening speed of nylon 6 particles during filtration. However, this device cannot automatically fill the packaging bag with chips and remove them to the outside. Summary of the Invention

[0004] To address the above problems, this invention provides a nylon 6 modified chip production apparatus and method. The drive mechanism can automatically fill the packaging bag with chips and remove them, effectively solving the problems in the background art.

[0008] Preferably, the driving mechanism includes a conveyor belt with rubber partitions evenly spaced on it, and an installation frame for opening the packaging bag is provided between two of the rubber partitions; a blocking plate for blocking the drying device is slidably connected to the bottom of the drying device, and an operating mechanism for placing slices into the packaging bag is fixedly connected to the drying device.

[0009] The operating mechanism is fixedly connected to a pushing mechanism for pushing the mounting frame filled with slices out, and the back of the conveyor belt is provided with a placement plate for catching the mounting frame.

[0010] Preferably, the operating mechanism includes a bidirectional motor installed in the drying device, with a first rotating column fixedly connected to the power output ends on both sides of the bidirectional motor, a first connecting rod fixedly connected to the side of the first rotating column away from the bidirectional motor, and a backing plate fixedly connected to the side of the first connecting rod away from the first rotating column.

[0011] The outer wall of the drying device is rotatably connected to a second rotating column, and a retaining spring is provided between the second rotating column and the drying device. The second rotating column is fixedly connected to a first cooperating rod and a second cooperating rod away from the outer wall of the drying device. The top of the blocking plate is provided with an anti-impact groove, and the top of the blocking plate is fixedly connected to a first fixing plate and a second fixing plate. The anti-impact plate can be pressed against the first fixing plate and the first cooperating rod. The front of the drying device is fixedly connected to a fixing column for abutting against the first cooperating rod. The second cooperating rod can be pressed against the second fixing plate.

[0012] Preferably, the pushing device includes a third rotating column rotatably connected to the front of the drying device, a one-way gear fixedly connected to the outer wall of the third rotating column, teeth provided on the top of the blocking plate, and the one-way gear meshing with the teeth; a belt is sleeved between the third rotating column and the power column of the conveyor belt.

[0013] The third rotating column is fixedly connected to a first bevel tooth on the side away from the drying device. A C-shaped rod is fixedly connected to the front of the drying device. A bearing seat is fixedly connected to one side of the C-shaped rod. A fourth rotating column is rotatably connected inside the bearing seat. A second bevel tooth is fixedly connected to the top of the fourth rotating column. The first bevel tooth and the second bevel tooth mesh with each other.

[0014] A disc is fixedly connected to the bottom of the fourth rotating column, and a second connecting rod is fixedly connected to the outer wall of the disc. A hinge rod is hinged to the side of the second connecting rod away from the disc. A push rod for pushing the mounting frame is slidably connected to the top of the C-shaped rod. The side of the hinge rod away from the second connecting rod is hinged to the push rod.

[0015] Preferably, a support base is fixedly installed at the bottom of the drying device.

[0016] A method for producing modified nylon 6 chips includes the following steps:

[0017] Step 1: Additives and caprolactam additives are placed into the melting device to generate a melt. Then, glass fiber is placed into the melting device through the feeding device to generate a uniformly mixed melt.

[0018] Step 2: The melt enters the pelletizing device through the screw compressor. The colloid that comes out at this time enters the cooling water through the filter screen, so that the melt becomes strip-shaped and is pelletized in the pelletizing device.

[0019] Step 3: Pour the diced slices into a gourd-shaped extraction device for extraction, so that the small molecules in the slices are separated out.

[0020] Step 4: Place the extracted slices into a drying device for drying. Hot nitrogen gas is circulated through the middle pipe of the drying device to dry the moisture on the surface of the slices, and hot nitrogen gas is circulated through the bottom pipe of the drying device to dry the moisture inside the slices.

[0021] Step 5: Start the bidirectional motor power supply. The bidirectional motor drives the first rotating column to rotate, which in turn drives the stop plate to rotate. The stop plate presses against the first fixed plate, causing the blocking plate to move and opening the bottom of the drying device. This allows the slices to fall into the packaging bag at the bottom, filling the bag with slices. The moving blocking plate moves its teeth, while the one-way gear remains in the stopped state. Then, the stop plate continues to rotate, pressing down the first mating rod. The pressed-down first mating rod drives the second rotating column to rotate, which in turn drives the second mating rod to push the second fixed plate, causing the blocking plate to move and block the bottom of the drying device, preventing the slices from leaking out. The blocking plate drives the teeth on it to move, the moving teeth drive the one-way gear to rotate, the one-way gear drives the third rotating column to rotate, the third rotating column drives the conveyor belt to move the installation frame full of slices to the next position; at this time, the rotating third rotating column drives the first bevel tooth to rotate one revolution, and through meshing, drives the second bevel tooth to rotate one revolution, thereby driving the fourth rotating column and the disc to rotate one revolution. The rotating disc, through the cooperation of the second connecting rod and the hinge rod, causes the push rod to move back and forth. When pushing forward, it pushes the installation frame full of material onto the placement plate, and then retracts. The above operation is repeated to obtain a large number of packaging bags full of slices.

[0022] Step 6: The packaged slices are transported to a fixed location for collection using a conveyor device.

[0023] Compared with the prior art, the beneficial effects of the present invention are: the nylon 6 modified chip production device and production method have a reasonable structure and the following advantages:

[0024] 1. The feeding mechanism directly feeds the glass fiber into the melt, reducing the costs of packaging, transportation, and melting of the chips.

[0025] 2. The gourd-shaped extraction device can improve the extraction efficiency.

[0026] 3. The drying device uses hot nitrogen gas flowing through the middle pipe to dry the surface moisture of the slices, and hot nitrogen gas flowing through the bottom pipe to dry the interior moisture of the slices.

[0027] 4. The set operating mechanism can automatically put approximately the same amount of slices into the packaging bag.

[0028] 5. The set push device can push the packaging bags filled with slices onto the placement plate; together with the conveyor and operating device, a large number of packaging bags filled with slices can be automatically pushed onto the placement plate. Attached Figure Description

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figures 1 to 7This invention provides a technical solution: a production apparatus and method for modified nylon 6 chips, comprising a fixed base plate, on which a melting device 33, a pelletizing device 34, an extraction device 35, a drying device 1, a packaging device 36, and a conveying device 37 are sequentially fixed. The melting device 33 is equipped with a feeding device 38 for feeding glass fiber, and the packaging device 36 is equipped with a drive mechanism for automatically filling and removing the chips from the packaging bag. When production of modified chips is required, additives and caprolactam additives are first placed into the melting device 33 to generate a melt. Then, glass fiber is placed into the melting device 33 through the feeding device 38 to generate a uniformly mixed melt. The melt then enters the pelletizing device 34 through a screw compressor. At this time, the colloid passes through a filter screen into cold water for cooling, causing the melt to become strip-shaped, which is then pelletized in the pelletizing device 34. After pelletizing, the product is poured into the extraction device 35 for extraction, allowing the small molecules in the chips to be separated. The extracted slices are then placed in drying device 1 for drying. The dried slices are automatically loaded into a packaging bag by a drive mechanism and removed. The packaged slices are then transported to a fixed location for collection by a conveying device 37.

[0039] Specifically, the extraction device 35 is gourd-shaped. The slices containing the mixture are poured into the extraction device 35. Because the extraction device 35 is gourd-shaped, the slices and mixture are introduced into the extraction device 35 at a faster speed. The faster slices result in a better extraction effect in the extraction solution.

[0040] Specifically, the drying device 1 has pipes for passing nitrogen gas in the middle and at the bottom. The hot nitrogen gas passing through the middle pipe dries the moisture on the surface of the slices, while the hot nitrogen gas passing through the bottom pipe dries the moisture inside the slices.

[0041] Specifically, the packaging device 36 includes a conveyor belt 4, on which rubber partitions 31 are equidistantly arranged, and between two rubber partitions 31 is an installation frame 23 for opening the packaging bag; the bottom of the drying device 1 is slidably connected to a blocking plate 14 for blocking the drying device, and the drying device 1 is fixedly connected to an operating mechanism for placing slices into the packaging bag.

[0042] A pushing mechanism is fixedly connected to the operating mechanism to push the mounting frame 23 filled with slices out. A placement plate 30 is provided on the back of the conveyor belt 4 to catch the mounting frame 23. After the dried slices are cooled, they need to be collected. At this time, the operating mechanism is started to move the slices in the drying device 1 into the packaging bag in the mounting frame 23. After the packaging bag is full, it blocks the bottom of the drying device 1 to prevent slices from leaking out. Then, when the drying device 1 is turned off, the conveyor belt 4 is moved to a position, and during the movement, the previous mounting frame 23 filled with slices is moved onto the placement plate 30 for collection. This facilitates subsequent transportation. The above actions are repeated continuously to obtain a large number of packaging bags full of slices.

[0043] Specifically, the drive mechanism includes a bidirectional motor 32 installed in the drying device 1. The power output ends on both sides of the bidirectional motor 32 are fixedly connected to a first rotating column 15. A first connecting rod 16 is fixedly connected to the side of the first rotating column 15 away from the bidirectional motor 32. A backing plate 18 is fixedly connected to the side of the first connecting rod 16 away from the first rotating column 15.

[0044] A second rotating column 11 is rotatably connected to the outer wall of the drying device 1. A retaining spring is provided between the second rotating column 11 and the drying device 1. A first mating rod 10 and a second mating rod 12 are fixedly connected to the second rotating column 11 away from the outer wall of the drying device 1. An anti-impact groove is provided on the top of the blocking plate 14. A first fixing plate 17 and a second fixing plate 13 are fixedly connected to the top of the blocking plate 14. The abutment plate 18 can be pressed against the first fixing plate 17 and the first mating rod 10. A fixing column 9 for abutting against the first mating rod 10 is fixedly connected to the front of the drying device 1. The second mating rod 12 can be pressed against the second fixing plate 13. The bidirectional motor 32 is powered on, causing the first rotating column 15 to rotate, which in turn causes the abutment plate 18 to rotate. The abutment plate 18 presses against the first fixed plate 17, causing the blocking plate 14 to move and opening the bottom of the drying device 1, allowing the slices to fall into the packaging bag at the bottom. Then the abutment plate 18 continues to rotate, pressing down the first mating rod 10. The pressed-down first mating rod 10 drives the second rotating column 11 to rotate, and then the second rotating column 11 drives the second mating rod 12 to push the second fixed plate 13, thereby causing the blocking plate 14 to move and block the bottom of the drying device 1, preventing the slices from leaking out.

[0045] Specifically, the pushing device includes a third rotating column 19 rotatably connected to the front of the drying device 1. A one-way gear 20 is fixedly connected to the outer wall of the third rotating column 19. The top of the blocking plate 14 is provided with teeth 21. The one-way gear 20 and the teeth 21 mesh with each other. A belt 5 is sleeved between the third rotating column 19 and the power column of the conveyor belt 4.

[0046] The third rotating column 19 is fixedly connected to the side away from the drying device 1 with a first bevel tooth 24. The front of the drying device 1 is fixedly connected with a chamfered rod 3. A bearing seat 8 is fixedly connected to one side of the chamfered rod 3. A fourth rotating column 6 is rotatably connected inside the bearing seat 8. A second bevel tooth 25 is fixedly connected to the top of the fourth rotating column 6. The first bevel tooth 24 and the second bevel tooth 25 mesh with each other.

[0047] The bottom of the fourth rotating column 6 is fixedly connected to a disc 26, the outer wall of the disc 26 is fixedly connected to a second connecting rod 7, and the side of the second connecting rod 7 away from the disc 26 is hinged to a hinge rod 27. The top of the U-shaped rod 3 is slidably connected to a push rod 28 for pushing the mounting frame 23, and the side of the hinge rod 27 away from the second connecting rod 7 is hinged to the push rod 28. The moving block plate 14 drives the teeth 21 on it to move, and the moving teeth 21 drive the one-way gear 20 to rotate. Only movement in one direction will drive the one-way gear 20 to rotate. Each time the block plate 14 moves back and forth, it will drive the third rotating column 19 to rotate once and stop once. The third rotating column 19 drives the conveyor belt 4 to move via the belt 5. When stationary, it collects materials. When rotating, it moves the packaging bag full of slices to another position. At this time, when moving to the new position, the rotating third rotating column 19 drives the first bevel tooth 24 to rotate. Through meshing, it drives the second bevel tooth 25 to rotate, thereby driving the fourth rotating column 6 and the disc 26 to rotate circumferentially. The circumferentially rotating disc 26, through the cooperation of the second connecting rod 7 and the hinge rod 27, causes the push rod 28 to move back and forth. When pushing forward, it pushes the mounting frame 23 full of materials onto the placement plate 3. Then it retracts, which is exactly one rotation of the disc 26, that is, one back and forth movement.

[0048] Specifically, a support base 2 is fixedly installed at the bottom of the drying device 1, ensuring that the drying device is stably installed on the ground.

[0049] A method for producing modified nylon 6 chips includes the following steps:

[0050] Step 1: Additives and caprolactam additives are placed into the melting device 33 to generate a melt, and then glass fiber is placed into the melting device 33 through the feeding device 38 to generate a uniformly mixed melt.

[0051] Step 2: The melt enters the pelletizing device 34 through the screw compressor. At this time, the colloid that comes out enters the cooling water through the filter screen, so that the melt becomes strip-shaped and is pelletized in the pelletizing device 34.

[0052] Step 3: Pour the diced slices into the gourd-shaped extraction device 35 for extraction, so that the small molecules in the slices are separated out.

[0053] Step 4: Place the extracted slices into drying device 1 for drying. Hot nitrogen gas is circulated through the middle pipe of drying device 1 to dry the moisture on the surface of the slices, and hot nitrogen gas is circulated through the bottom pipe of drying device 1 to dry the moisture inside the slices.

[0054] Step 5: Start the power supply of the bidirectional motor 32. The bidirectional motor 32 drives the first rotating column 15 to rotate, which in turn drives the abutment plate 18 to rotate. The abutment plate 18 presses against the first fixed plate 17, causing the blocking plate 14 to move, opening the bottom of the drying device 1 and allowing the slices to fall into the packaging bag at the bottom, filling the bag with slices. The moving blocking plate 14 drives the teeth 21 on it to move, while the one-way gear 20 remains in the stopped state. Then, the abutment plate 18 continues to rotate, pressing down the first mating rod 10. The pressed-down first mating rod 10 drives the second rotating column 11 to rotate, and then the second rotating column 11 drives the second mating rod 12 to push the second fixed plate 13, thereby moving the blocking plate 14 and blocking the bottom of the drying device 1, preventing the slices from leaking out. The moving stop plate 14 drives the teeth 21 on it to move, the moving teeth 21 drives the one-way gear 20 to rotate, the one-way gear 20 drives the third rotating column 19 to rotate, the third rotating column 19 drives the conveyor belt 4 to move through the belt 5, so that the installation frame 23 filled with slices moves to the next position; at this time, the rotating third rotating column 19 drives the first bevel tooth 24 to rotate one revolution, and through meshing, drives the second bevel tooth 25 to rotate one revolution, thereby driving the fourth rotating column 6 and the disc 26 to rotate one revolution. The rotating disc 26, through the cooperation of the second connecting rod 7 and the hinge rod 27, causes the push rod 28 to move back and forth. When pushing forward, it pushes the installation frame 23 filled with material onto the placement plate 3, and then retracts. The above operation is repeated to obtain a large number of packaging bags full of slices.

[0055] Step 6: The packaged slices are transported to a fixed location for collection via the conveyor device 37.

[0056] Working principle: When modified chips need to be produced, additives and caprolactam additives are first placed into the melting device 33 to generate a melt. Then, glass fiber is placed into the melting device 33 through the feeding device 38 to generate a uniformly mixed melt. The melt then enters the pelletizing device 34 through a screw compressor. At this time, the colloid passes through a filter screen into cold water for cooling, causing the melt to become strip-shaped and then pelletized in the pelletizing device 34. After pelletizing, the pellets are poured into a gourd-shaped extraction device 35 for extraction, which separates the small molecules from the chips. The extracted slices are then placed in drying device 1 for drying. Hot nitrogen gas is circulated through the middle pipe of drying device 1 to dry the surface moisture of the slices, and hot nitrogen gas is circulated through the bottom pipe of drying device 1 to dry the internal moisture of the slices. At this time, the power supply of bidirectional motor 32 is turned on. Bidirectional motor 32 drives the first rotating column 15 to rotate, and then drives the abutment plate 18 to rotate. The abutment plate 18 presses against the first fixed plate 17, causing the blocking plate 14 to move and opening the bottom of drying device 1, allowing the slices to fall into the packaging bag at the bottom. Then the abutment plate 18 continues to rotate, pressing down the first mating rod 10. The pressed-down first mating rod 10 drives the second rotating column 11 to rotate, and then the second rotating column 11 drives the second mating rod 12 to push the second fixed plate 13, thereby causing the blocking plate 14 to move and block the bottom of drying device 1, preventing the slices from leaking out. The moving stop plate 14 drives the teeth 21 on it to move, and the moving teeth 21 drive the one-way gear 20 to rotate. Only movement in one direction will drive the one-way gear 20 to rotate. Each time the stop plate 14 moves back and forth, it will drive the third rotating column 19 to rotate once and stop once. The third rotating column 19 drives the conveyor belt 4 to move via the belt 5. When stationary, it collects material. When rotating, it moves the packaging bag full of slices to another position. At this time, when moving to the new position, the rotating third rotating column 19 drives the first bevel tooth 24 to rotate, and through meshing, it drives the second bevel tooth 25 to rotate, thereby driving the fourth rotating column 6 and the disc 26 to rotate circumferentially. The circumferentially rotating disc 26, through the cooperation of the second connecting rod 7 and the hinge rod 27, causes the push rod 28 to move back and forth. When pushing forward, it pushes the mounting frame 23 full of material onto the placement plate 3. Then it retracts, which is exactly one rotation of the disc 26, that is, one back and forth movement. Thus, a large number of packaging bags full of slices are obtained. The packaged slices are then transported to a fixed location for collection via conveyor 37.

A method for producing nylon 6 modified chips, using the nylon 6 modified chip production apparatus as described in claim 4, characterized in that: Includes the following steps: Step 1: Additives and caprolactam additives are placed into the melt device (33) to generate a melt, and then glass fiber is placed into the melt device (33) through the feeding device (38) to generate a uniformly mixed melt; Step 2: The melt enters the pelletizing device (34) through the screw press. At this time, the colloid that comes out enters the cold water through the filter screen to cool, so that the melt becomes strips and is pelletized in the pelletizing device (34). Step 3: Pour the diced slices into a gourd-shaped extraction device (35) for extraction, so that the small molecules in the slices are separated out. Step 4: Place the extracted slices into the drying device (1) for drying. Hot nitrogen gas is passed through the middle pipe of the drying device (1) to dry the moisture on the surface of the slices, and hot nitrogen gas is passed through the bottom pipe of the drying device (1) to dry the moisture inside the slices. Step 5: Start the power supply of the bidirectional motor (32). The bidirectional motor (32) drives the first rotating column (15) to rotate, and then drives the abutment plate (18) to rotate. The abutment plate (18) presses against the first fixed plate (17), causing the blocking plate (14) to move, opening the bottom of the drying device (1), allowing the slices to fall into the packaging bag at the bottom, and filling the packaging bag with slices; the moving blocking plate (14) drives the teeth (21) on it to move, and the one-way gear (20) remains in the stopped state; then the abutment plate (18) continues to rotate, and the abutment plate (18) presses down the first mating rod (10). The pressed-down first mating rod (10) drives the second rotating column (11) to rotate, and then the second rotating column (11) drives the second mating rod (12) to push the second fixed plate (13), thereby causing the blocking plate (14) to move, blocking the bottom of the drying device (1), so that the slices cannot leak out; the moving The blocking plate (14) drives the teeth (21) on it to move. The moving teeth (21) drive the one-way gear (20) to rotate. The one-way gear (20) drives the third rotating column (19) to rotate. The third rotating column (19) drives the conveyor belt (4) to move through the belt (5), so that the installation frame (23) filled with slices moves to the next position. At this time, the rotating third rotating column (19) drives the first bevel tooth (24) to rotate once. Through meshing, it drives the second bevel tooth (25) to rotate once, thereby driving the fourth rotating column (6) and the disc (26) to rotate once. The rotating disc (26) through the cooperation of the second connecting rod (7) and the hinge rod (27) makes the push rod (28) move back and forth. When it pushes forward, it pushes the installation frame (23) filled with material onto the placement plate (30) and then retracts. The above operation is repeated to obtain a large number of full-bag packaging bags of slices. Step 6: The packaged slices are transported to a fixed location for collection via a conveying device (37).
