Description

Technical Field

[0001] The present application relates to the field of nylon processing, and in particular to a nylon polymerization modification mixing device. Background Art

[0002] As plastics are used more and more in our lives, the use of nylon is also becoming more and more extensive. Some nylons that are specifically suitable for special scenarios and have special properties have also emerged, such as flame-retardant nylon. In the production process of flame-retardant nylon, it is necessary to mix particles with other properties into the flame-retardant particles, such as particles that improve toughness and particles that improve strength, so as to achieve composite nylon with flame-retardant properties and improve the performance of nylon.

[0003] As the performance of nylon improves, the ratio of nylon particles during mixing is also becoming more complicated. If moisture is mixed in the nylon particles, it is equivalent to adding an extra water component, which not only affects the ratio, but also affects the melting temperature, thereby affecting the performance of the finished product. Summary of the Invention

[0004] In order to improve the problem of moisture inclusion during nylon particle mixing, the present application provides a nylon polymerization modification mixing device.

[0005] The present application provides a nylon polymerization modification mixing device, which adopts the following technical solution:

A transmission channel for transmitting particles is provided between the feed port and the discharge port. A filter plate for filtering particles is provided in the transmission channel. An adsorption component for absorbing moisture is provided in the transmission channel, and the filter plate is located between the adsorption component and the feed port.

[0007] By adopting the above technical solution, the size of the particles is filtered through the filter plate, and then the moisture on the particles is adsorbed by the adsorption component, thereby reducing the moisture entrained on the particles and reducing the probability of moisture mixing into subsequent processing steps, thereby affecting the performance of the finished product, facilitating subsequent processing, and improving the yield of the finished product.

[0008] Optionally, the adsorption component includes an adsorption plate arranged in the transmission channel and a sliding plate attached to the adsorption plate, the adsorption plate is used to absorb moisture, a number of water absorption holes are provided on the adsorption plate for particles to fall into, the particles in the water absorption holes are pressed against the sliding plate, a sliding yield groove is provided on the inner wall of the transmission channel, a sliding drive component for driving the sliding plate to slide is provided in the sliding yield groove, the sliding plate slides in the sliding yield groove, and a falling hole is provided on the sliding plate, and the falling hole corresponds to the water absorption hole.

[0009] By adopting the above technical solution, the particles are adsorbed by the adsorption plate. When the particles fall into the water absorption hole, the moisture on the side wall of the particle is fully absorbed by the inner wall of the water absorption hole surrounding the particle. Then, the sliding plate slides to make the particles that are in contact with the sliding plate rotate in the water absorption hole, so that the side wall of the particle can contact the inner wall of the water absorption hole more evenly, so that the moisture on the particle is more fully absorbed, and the moisture on the side wall of the particle is further removed, so that the moisture absorption is more thorough.

[0010] Optionally, the sliding drive assembly includes a sliding drive member arranged in the main body, a turntable is provided on the rotating shaft of the sliding drive member, a push rod is hinged on the turntable, a sliding rod is provided on the inner wall of the sliding groove, the sliding rod is inserted into and slides in the push rod, and the end of the push rod is provided on the sliding plate.

[0011] By adopting the above technical solution, the turntable is driven to rotate by rotating the rotating shaft of the sliding drive member, and the rotation of the sliding plate is achieved by the plug-in sliding of the sliding rod and the push rod. At this time, the sliding plate slides in the circumferential direction, so that the particles that are in contact with the sliding plate can rotate more fully, so that each side wall of the particle is in contact with the inner wall of the water absorption hole, further improving the moisture on the side wall of the particle, and making the moisture absorption more thorough.

[0012] Optionally, a heating wire for heating is provided in the adsorption plate, a dehumidifying component for absorbing moisture is provided in the transmission channel, and a vibration driving component is provided on the filter plate.

[0013] By adopting the above technical solution, the moisture absorbed on the adsorption plate is evaporated and discharged through the heating wire, and then the moisture at the evaporation point of the heating wire is absorbed and discharged by the dehumidification component to be removed, thereby extending the service life of the adsorption plate and allowing the adsorption plate to be reused without replacement.

[0014] Optionally, a crushing assembly for crushing particles is provided between the filter plate and the feed port, the crushing assembly includes at least two crushing rollers rotatably arranged in a transmission path, a plurality of crushing blocks are provided on the crushing rollers, a feed roller is provided between the crushing assembly and the feed port, the feed roller transmits particles, and the particles are transmitted from the direction of the crushing roller close to the ground for crushing.

[0015] By adopting the above technical solution, the particles are crushed by rotating the crushing roller, thereby reducing the size of the particles, facilitating subsequent filtration, and making subsequent mixing more thorough. The crushing block increases the pressure when crushing the particles, thereby improving the crushing efficiency.

[0016] Optionally, a rotating give way groove is provided on the inner wall of the transmission channel, the feed roller is embedded in the rotating give way groove, a slide groove is provided on the feed roller, a baffle plate slides in the slide groove, the baffle plate is used to push the particles in the transmission channel for transmission, and a first elastic member is provided between the baffle plate and the inner wall of the slide groove, the first elastic member is used to push the baffle plate to slide out of the slide groove.

[0017] By adopting the above technical solution, the baffle plate rotates with the feed roller. When the baffle plate enters the rotating give way groove, the baffle plate will conflict with the inner wall of the transmission path, causing the baffle plate to retreat into the slide groove, and then conflict with the inner wall of the rotating give way groove as the feed roller rotates. When the baffle plate rotates out of the rotating give way groove, the baffle plate will pop out under the action of the first elastic member. At this time, as the feed roller rotates, the baffle plate will push the particles to continue to be transported, thereby achieving a bottom-up transmission that overcomes gravity, making subsequent crushing more thorough, reducing the probability of particles passing through when adjacent crushing rollers just rotate to form a gap, and improving the crushing efficiency of the particles.

[0018] Optionally, a feed trough is provided on the crushing roller, a feed plate slides in the feed trough, a second elastic member is provided between the feed plate and the inner wall of the feed trough, the second elastic member is used to push the feed plate to slide out of the feed trough, the feed plates on adjacent crushing rollers cooperate and interfere with each other, the end of the feed plate is arc-shaped, and a stopper for interfering with the feed plate is provided on the inner wall of the feed trough.

[0019] When the feed plate is fully withdrawn into the feed trough, the end of the feed plate will contact the stop block. At this time, the ends of the two feed plates will crush and crush the particles. The force transmission is achieved through the stop block, which reduces the probability of the feed plate continuing to retreat into the feed trough when crushing the particles due to insufficient elasticity of the second elastic member, thereby improving the efficiency of the feed plate in crushing the particles. When the particles are crushed, as the crushing roller continues to rotate, the feed plate pops up again under the action of the second elastic member, and the feed plate will continue to rotate and transmit the particles to the filter plate, thereby improving the transmission efficiency. The arc-shaped end of the feed plate reduces the probability of the two feed plates getting stuck after conflict, thereby improving the rotation efficiency.

[0020] Optionally, a sealing clearance groove is opened on the inner wall of the feed trough, a sealing plate is rotatably arranged in the sealing clearance groove, the sealing plate rotates and contacts the feed plate, and a sealing film is arranged between the sealing plate and the inner wall of the feed trough.

[0021] By adopting the above technical solution, the sealing plate is pressed against the side wall of the feed plate, and the sealing film is used to seal the space between the end of the arc-shaped feed plate and the inner wall of the feed trough, thereby reducing the probability of particles falling therein and making the sliding of the feed plate smoother.

[0022] Optionally, a guide plate is provided on the inner wall of the transmission channel, and a crushing groove is provided on the guide plate. The crushing groove is used for passing the crushed particles. The guide plate is inclined toward the filter plate. A return channel is also provided on the inner wall of the transmission channel where the filter plate is located. The return channel is used to slide in particles whose size is larger than the size that can be filtered through the filter plate. The return channel is connected between the feed roller and the crushing assembly.

[0023] By adopting the above technical solution, the particles transmitted after crushing are guided by the guide plate, so that the particles falling on the guide plate slide onto the filter plate according to the inclination angle of the guide plate, thereby improving the transmission efficiency.

[0024] Optionally, a mixing roller for mixing particles is rotatably provided in the transmission channel, and the mixing roller is located between the adsorption component and the discharge port.

[0025] By adopting the above technical solution, the particles are mixed by a mixing roller, so that the particles are mixed more evenly, which facilitates subsequent processing and melting.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0046] Reference Figure 2 A rotational clearance groove 51 is provided on the inner wall of the transmission path 13, and the feed roller 5 is embedded in the rotational clearance groove 51. The rotation axis of the feed roller 5 is inserted into the inner wall of the transmission path 13 outside the rotational clearance groove 51, and the outer wall of the feed roller 5 is in contact with the inner wall of the rotational clearance groove 51. A plurality of chutes 52 are provided on the outer wall of the feed roller 5. The chutes 52 are evenly distributed in the rotation direction of the feed roller 5. A baffle plate 53 slides in the chutes 52. The outer wall of the baffle plate 53 is in contact with the inner wall of the chutes 52 to prevent particles from falling in.

The crushed particles are passed through the crushing groove 46. The guide plate 45 is tilted toward the filter plate 2. The crushed particles fall onto the guide plate 45 and slide onto the filter plate 2. A return channel 22 is also formed on the inner wall of the conveyor channel 13 where the filter plate 2 is located. One end of the return channel 22 is located at a position on the filter plate 2 away from the adsorption plate 31. The other end of the return channel 22 is connected between the feed roller 5 and the crushing assembly 4. The return channel 22 is used to allow particles larger than the cross-sectional diameter of the filter pores of the filter plate 2 to slide into.

[0053] Reference Figure 2 Two mixing rollers 7 for mixing the particles are also rotatably installed in the transmission channel 13. The mixing rollers 7 are located between the adsorption component 3 and the discharge port 12. A switch valve is installed on the discharge port 12. The discharge of the discharge port 12 can be controlled by opening and closing the switch valve.

[0054] The implementation principle of a nylon polymerization modification mixing device in an embodiment of the present application is as follows: after the staff pours the particles from the feed port 11, the feed roller 5 is first rotated to make the baffle plate 53 push the particles forward to the crushing roller 41, and the crushing roller 41 rotates, and the particles are scooped up by the feed plate 44 and sent to between the adjacent crushing rollers 41 for crushing and crushing, and then the particles coming out from between the adjacent crushing rollers 41 will slide onto the guide plate 45, slide to the filter plate 2 through the inclined guide plate 45, and the particles of qualified size pass through the filter plate 2 into the water absorption hole 33. At this time, the sliding plate 32 is used to slide the particles in the water absorption hole 33, so that the moisture on the particles is fully absorbed. When the water absorption hole 33 is aligned with the drop hole 36, the particles continue to fall to the mixing roller 7 for mixing, and finally are discharged through the discharge port 12.
