Description

Technical Field

[0001] The utility model belongs to the technical field of drying devices, and particularly relates to a drying device for producing nylon super-tough toughening compatibilizer. Background Technique

[0002] Nylon super-tough toughening compatibilizer is an additive used to improve the performance of nylon materials. Specifically, it is used to improve the toughness of nylon materials and increase the compatibility between different materials. The general production process of nylon super-tough toughening compatibilizer is as follows: raw materials are mixed in a certain proportion, the mixed materials are melted at high temperature to make them fully mixed, chemical reactions are carried out under certain conditions to generate toughening compatibilizer, the reacted materials are extruded and formed through an extruder, the extruded materials are cooled and shaped, the shaped materials are crushed to obtain the required particle size, the crushed materials are screened to remove too large or too small particles, and then the finished products can be packaged. Therefore, it is necessary to dry the toughening compatibilizer particles before screening.

[0003] The existing drying device for producing toughening compatibilizer passes hot air into the device through multiple hot air pipes, and then controls the carrier plate to move left and right and up and down, driving the toughening compatibilizer particles carried by the carrier plate to vibrate. In this way, the toughening compatibilizer particles can be dried more fully. However, the movement of the toughening compatibilizer particles on the carrier plate is realized by vibration, and the movement process has uncertainty. It cannot ensure that the dried toughening compatibilizer particles are completely removed from the drying device, and may cause the mixing of undried and dried toughening compatibilizer particles, thus affecting the drying efficiency of the device. Summary of the Utility Model

The output end of the motor is fixed with a driving wheel. The circumferential side surface of the driving wheel is engaged with a driven wheel.

The number of the first pins is greater than that of the second pins. The circumferential side surface of the gear teeth is engaged with a direction-changing wheel.

[0008] The present utility model is further arranged such that on the other side surface of the driven wheel, a first rotating shaft rotatably engaged with the second support plate is fixed.

The second rotating shaft is rotatably engaged with the first support plate.

[0009] The present utility model is further arranged such that on the tops of the first support plate and the second support plate, support rings are fixed. An annular groove is formed on the inner circumferential side surface of the support ring. A number of fixed shafts are fixedly arranged on the inner wall of the annular groove in a circumferential array. A number of balls are rotatably engaged with the circumferential side surfaces of the fixed shafts. Two fixed rings are fixed on the outer circumferential side surface of the roller. The fixed rings are rotatably engaged with the annular groove.

[0010] The present utility model is further arranged such that on one side of the first support plate, a air supply component is fixedly arranged. The air supply component includes a cam fixed at one end of the second rotating shaft. A piston rod is slidably engaged with the circumferential side surface of the cam.

[0011] An air suction pipe is communicated with the end of the piston cylinder, and an exhaust pipe is communicated with the circumferential side surface of the piston cylinder near its end. A first one-way valve and a second one-way valve are respectively arranged on the air suction pipe and the exhaust pipe. A spring is sleeved on the circumferential side surface of the piston rod inside the piston cylinder. One end of the spring is fixedly connected with the piston, and the other end of the spring is fixedly connected with the piston cylinder.

[0012] The present utility model is further arranged such that on one side of the conveying device, a mounting plate is fixed. An air vent plate is fixed at the inner top of the mounting plate. One end of the air vent plate is fixed with an air pipe. The air pipe is communicated with the exhaust pipe through a hose.

[0013] A cavity is formed inside the air vent plate. A through hole is formed at one end of the air vent plate. A number of air vent holes are linearly arrayed at the bottom of the air vent plate. The air vent holes are communicated with the cavity.

[0016] 1. In the utility model, the motor drives the driving wheel to rotate clockwise, and the driving wheel drives the driven wheel meshed with it externally to rotate counterclockwise. At this time, the pin one and pin two on one side of the driving wheel and the driven wheel sequentially push the external teeth of the reversing wheel. Because the rotation directions of the driving wheel and the driven wheel are opposite, the reversing wheel realizes periodic forward and reverse rotation movements. The reversing wheel drives the teeth fixed on the circumferential side of the roller to rotate, so that the roller synchronously performs periodic forward and reverse rotation movements. Through the forward and reverse rotation movements of the roller, the toughening compatibilizer particles in the roller are promoted to flip, so as to avoid the toughening compatibilizer particles sticking to the inner wall of the roller and improve the drying efficiency of the toughening compatibilizer particles.

[0017] 2. In the utility model, when the reversing wheel rotates through the second rotating shaft, the cam will be driven to rotate forward and backward synchronously. When the cam rotates, it will drive the piston to reciprocate in the piston cylinder through the piston rod, so that the hot air in the heating chamber sequentially enters the ventilation plate through the air extraction pipe, the first one-way valve, the piston cylinder, the exhaust pipe, the second one-way valve, the hose and the air pipe, and then distributes the hot air to each position in the roller through the through holes, thereby replacing the air pump to convey hot air, reducing the manufacturing cost of the device, and the amount of hot air extracted and discharged from the heating chamber by the piston cylinder each time, avoiding that the hot air sucked from the heating chamber does not have enough heat.

[0018] Of course, it is not necessary for any product implementing the utility model to achieve all the above advantages simultaneously. Description of the Drawings

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] For specific embodiment 1, please refer to Figure 1-8, the utility model is a drying device for the production of a nylon super-tough toughening compatibilizer, including a first conveying device 1. One end of the first conveying device 1 is provided with a roller 3. A support assembly 4 is rotationally matched with the outer peripheral side of the roller 3. The other end of the roller 3 is provided with a second conveying device 2. The support assembly 4 includes a first support plate 401 and a second support plate 402. A bottom plate 403 is fixedly connected to the bottoms of the first support plate 401 and the second support plate 402. A spiral baffle 301 is fixedly connected to the inner peripheral side of the roller 3. A gear 302 is fixedly connected to the outer peripheral side of the roller 3. A direction-changing assembly 5 is fixedly connected to one side of the second support plate 402. The direction-changing assembly 5 includes a mounting base 501 fixedly connected to one side surface of the second support plate 402. A motor 502 is fixedly connected inside the mounting base 501. A driving wheel 503 is fixedly connected to the output end of the motor 502. A driven wheel 504 is meshed with the circumferential side of the driving wheel 503. A number of first pins 505 are fixedly connected to the side surface of the driving wheel 503 away from the motor 502. A number of second pins 506 are fixedly connected to the opposite side surface of the driven wheel 504. The number of the first pins 505 is greater than the number of the second pins 506. A direction-changing wheel 507 is meshed with the circumferential side of the gear 302.

[0032] The operation process of this embodiment is as follows: Start the motor 502. The driving wheel 503 is driven to rotate clockwise by the output shaft of the motor 502. The driving wheel 503 drives the driven wheel 504 meshed with it to rotate counterclockwise. The first pins 505 on one side of the driving wheel 503 and the second pins 506 on one side of the driven wheel 504 will alternately push the direction-changing wheel 507 to rotate. Because the driving wheel 503 and the driven wheel 504 rotate in opposite directions, the first pins 505 and the second pins 506 push the direction-changing wheel 507 to rotate periodically clockwise and counterclockwise. The direction-changing wheel 507 drives the roller 3 to rotate periodically forward and backward through the gear 302 meshed with it. And because the number of the first pins 505 is much greater than the number of the second pins 506, when the roller 3 rotates periodically forward and backward, it rotates clockwise overall. In this way, the toughening compatibilizer particles can roll from one end of the roller 3 along the spiral baffle 301 towards the other end of the roller 3. The conveying device includes a conveyor belt and a support frame. The conveyor belt is used for conveying materials, and the support frame is used for the fixed support of the conveyor belt and the installation and fixation of the cooperating components.

[0033] Specific embodiment two, please refer to Figure 1-8, on the basis of the first specific embodiment, specifically, a first rotating shaft 508 is fixed to one side surface of the driven wheel 504, and the first rotating shaft 508 is rotationally engaged with the second support plate 402. A second rotating shaft 509 passing through the first support plate 401 is fixed to one side surface of the deflector wheel 507, and the second rotating shaft 509 is rotationally engaged with the first support plate 401. Support rings 404 are fixed to the tops of the first support plate 401 and the second support plate 402. An annular groove 405 is formed in the inner circumferential surface of the support ring 404. A plurality of fixed shafts 406 are fixedly arranged on the inner wall of the annular groove 405 in a circumferential array. A plurality of balls 407 are rotationally engaged with the circumferential surfaces of the plurality of fixed shafts 406. Two fixed rings 303 are fixed to the outer circumferential surface of the drum 3, and the fixed rings 303 are rotationally engaged with the annular groove 405.

[0034] The operation process of this embodiment is as follows: When the motor 502 drives the first rotating shaft 508 on one side surface of the driven wheel 504 to rotate on the outer side surface of the second support plate 402 and the second rotating shaft 509 on one side surface of the deflector wheel 507 to rotate on the inner side surface of the first support plate 401 to drive the drum 3 to rotate, the fixed rings 303 fixed to the outer circumferential surface of the drum 3 are stuck in the annular groove 405. When the drum 3 rotates, the outer circumferential surface of the fixed ring 303 is rotationally engaged with the balls 407 to reduce the friction generated when the fixed ring 303 rotates in the annular groove 405.

[0035] For the third specific embodiment, please refer to Figure 1-8, on the basis of the first specific embodiment and the second specific embodiment, specifically, an air supply assembly 6 is fixedly arranged on one side of the first support plate 401. The air supply assembly 6 includes a cam 601 fixed to one end of the second rotating shaft 509. A piston rod 602 is slidably fitted on the circumferential surface of the cam 601. One end of the piston rod 602 is fixed with a piston 603. The circumferential surface of the piston 603 is slidably fitted with a piston cylinder 604 fixed to one side of the first support plate 401. An air suction pipe is communicated with the end of the piston cylinder 604, and an exhaust pipe is communicated with the circumferential surface of the piston cylinder 604 near its end. One-way valves 605 and 606 are respectively arranged on the air suction pipe and the exhaust pipe. A spring 607 is sleeved on the circumferential surface of the piston rod 602 inside the piston cylinder 604. One end of the spring 607 is fixedly connected with the piston 603, and the other end of the spring 607 is fixedly connected with the piston cylinder 604. An installation plate 304 is fixed to one side of the first conveying device 1. The inner top of the installation plate 304 is fixed with a ventilation plate 305. One end of the ventilation plate 305 is fixed with an air pipe 306. The air pipe 306 is communicated with the exhaust pipe through a hose. A cavity 307 is formed inside the ventilation plate 305. A through hole 308 communicated with the air pipe 306 is formed at one end of the ventilation plate 305. A plurality of ventilation holes 309 are linearly arranged at the bottom of the ventilation plate 305. The ventilation holes 309 communicate with the cavity 307. A heating component 7 is arranged inside the first support plate 401. The heating component 7 includes a heating chamber 701 formed inside the first support plate 401. A heating plate 702 is fixed to the inner wall of the heating chamber 701. An air intake groove 703 is formed through the inner wall of the heating chamber 701. The heating chamber 701 is communicated with the air suction pipe through a hose. Trapezoidal feeding ports 310 and trapezoidal discharging ports 311 are respectively fixed to both ends of the roller 3.

[0036] The operation process of this embodiment is as follows: when the reversing wheel 507 performs forward and reverse movements, the reversing wheel 507 will simultaneously drive the cam 601 to rotate synchronously through the second rotating shaft 509. When the cam 601 performs forward and reverse movements, it will drive the piston rod 602 to reciprocate, and cooperate with the spring 607 to keep one end of the piston rod 602 in contact with the circumferential side of the cam 601, so that the piston rod 602 drives the piston 603 to reciprocate in the piston cylinder 604. Using the air pressure difference, the hot air heated by the heating plate 702 in the heating chamber 701 sequentially passes through the suction pipe and the first one-way valve 605 and then enters the piston cylinder 604, and then the hot air in the piston cylinder 604 is extruded by the piston 603, so that the hot air in the piston cylinder 604 sequentially passes through the exhaust pipe, the second one-way valve 606 and the air pipe 306 and then enters the ventilation plate 305. When the conveying device 1 conveys the toughening compatibilizer particles to the trapezoidal feeding port 310 at one end of the drum 3, the toughening compatibilizer particles slide down from the trapezoidal feeding port 310 onto the spiral baffle 301. The drum 3 is driven to rotate by the motor 502, and the air pipe 306 conveys hot air to the cavity 307 inside the ventilation plate 305 through the through hole 308, and the hot air is discharged to each part inside the drum 3 through the ventilation holes 309, so as to dry the toughening compatibilizer particles in the drum 3. When the toughening compatibilizer particles slide down from the drum 3 into the trapezoidal discharge port 311 and then slide down from the trapezoidal discharge port 311 onto the conveying device 2, and are transmitted by the conveying device 2 for subsequent processing. To prevent solid particles from entering the cavity 307 through the ventilation holes 309, a barrier net needs to be fixed on the side surface of the ventilation plate 305 where the ventilation holes 309 are provided.

[0037] By setting the appropriate number of teeth of the reversing wheel 507 and the number of the first pin 505 and the second pin 506, when the output shaft of the motor 502 rotates clockwise and the reversing wheel 507 drives the cam 601 to perform forward and reverse movements synchronously, the cam 601 can rotate counterclockwise for a complete circle, and during this process, the cam 601 can perform multiple forward and reverse movements. This enables the cam 601 to drive the piston 603 to reciprocate different distances in the piston cylinder 604 each time through the piston rod 602, and the piston cylinder 604 extracts and discharges different volumes of hot air from the heating chamber 701 each time, so as to control the intake of cold air in the heating chamber 701, and cooperate with the heating plate 702 to heat the cold air just entering the heating chamber 701 in time to ensure that the hot air entering the drum 3 has sufficient heat.
