Description

Technical Field

[0001] This invention relates to the field of polyamide preparation mixing equipment technology, and in particular to a uniform mixing device for functional additives in polyamide production and its usage method. Background Technology

[0002] Polyamides possess excellent corrosion resistance, abrasion resistance, and barrier properties, and are widely used in fibers, injection molded products, and multilayer co-extruded films. Functional polyamides are fibers with special functions, produced by using natural or synthetic polymers as raw materials, modifying them with other auxiliaries, and then preparing spinning solutions, spinning, and post-treatment processes. Polyamide copolymerization modification can, to a certain extent, achieve molecular design by grafting or blocking other polymers or functional groups onto the polyamide molecular chain, thereby giving it desired properties such as high reinforcement and high flowability, as well as imparting functions such as flame retardancy, antibacterial properties, and cooling sensation. There are many auxiliaries that can copolymerize with polyamides, broadly classified into three categories: inorganic nanoparticles, organic polymers, and carbon nanotubes. The preparation of functional polyamides requires mixing the polyamide resin and auxiliaries using a high-speed mixer to facilitate subsequent spinning operations.

[0003] Some of the additives mixed with polyamide resin are in powder form. When the mixing device is opened, the suction generated by opening the lid will draw the powder from inside the mixing chamber and lift it up. When the powder falls to the connection area of ​​the mixing barrel, it is easy to be adsorbed on its surface, thereby affecting the sealing effect of the mixing device and causing material leakage during mixing. Therefore, we have proposed a uniform mixing device for functional additives in polyamide production and its usage method to solve the problems mentioned above. Summary of the Invention

[0014] A method for using a device for uniformly mixing functional additives in polyamide production includes the following steps:

[0015] Step 1: Extend the mixing tank lid and lift the telescopic cylinder to move the mixing tank lid fixing frame upward. As the mixing tank lid fixing frame moves upward, it also moves the mixing tank lid upward, injecting polyamide resin and additives into the interior of the mixing tank.

[0016] Step 2: Extend the telescopic cylinder of the dust removal mechanism's dust removal fixing seat. The telescopic cylinder pushes the dust removal fixing seat, allowing it to slide along the dust removal fixing seat slide rail groove and limit the movement of the dust removal fixing seat slide rail. This allows the lower surfaces of the lower cleaning duster and lower cleaning block to fit against the upper surface of the mixing tank. Then, retract the telescopic cylinder of the mixing tank cover lifting mechanism to move the mixing tank cover adjusting seat downwards, allowing the outer side of the lower end of the mixing tank cover adjusting seat to fit against the upper cleaning duster and upper cleaning block.

[0017] Step 3: Start the dust removal mechanism motor. The output end of the dust removal mechanism motor drives the dust removal mechanism gear to rotate. The dust removal mechanism gear meshes with the gear rack, thereby driving the dust removal mechanism to slide along the limit slider groove and limit the slider, so that the dust removal mechanism can rotate in a circle outside the mixing barrel. The lower cleaning duster dusts off the material powder adhering to the upper surface of the mixing barrel, and the upper cleaning duster dusts off the material powder adhering to the lower surface of the mixing barrel cover. Start the dust collection fan to suck up the dust dust dusted inside the upper and lower dust collection hoods. Filter the dust through the filter box. The filtered air is discharged through the air outlet pipe. The upper cleaning block wipes the lower surface of the mixing barrel cover, and the lower cleaning block wipes the upper surface of the mixing barrel. Wipe off the remaining dust again. After cleaning, retract the dust removal fixing seat telescopic cylinder to reset the dust removal fixing seat. Then retract the mixing barrel cover lifting telescopic cylinder to make the mixing barrel cover fit with the mixing barrel.

[0018] Step 4: Start the mixing motor. The output of the mixing motor drives the drive pulley to rotate. The drive pulley drives the driven pulley to rotate via a belt. The driven pulley drives the mixing roller to rotate. The rotating mixing roller drives the stirring paddle to rotate, thereby mixing and stirring the materials.

[0019] Step 5: After mixing is complete, control the discharge telescopic cylinder to retract. The discharge telescopic cylinder drives the unloading sliding mechanism to slide downward, so that the material enters the discharge pipe and is finally discharged through the discharge pipe.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. In this invention, the dust removal mechanism is used to dust up and suck up dust, thereby preventing dust from remaining at the sealing connection and affecting the sealing effect. During use, the telescopic cylinder of the dust removal mechanism's fixing seat extends, pushing the dust removal fixing seat and allowing it to slide along the limiting groove of the dust removal fixing seat slide against the limiting rail, so that the lower surfaces of the lower cleaning duster and lower cleaning block are in contact with the upper surface of the mixing tank. Then, the telescopic cylinder of the mixing tank lid is retracted, causing the mixing tank lid adjusting seat to move downwards, so that the outer side of the lower end of the mixing tank lid adjusting seat is in contact with the upper cleaning duster and upper cleaning block. The dust removal mechanism motor is started, and the output end of the dust removal mechanism motor drives the dust removal mechanism gear to rotate. Through the meshing connection between the dust removal mechanism gear and the gear rack, the dust removal mechanism is driven to slide along the limiting slider groove against the limiting slider. The dust removal mechanism rotates in a circular motion outside the mixing drum. The lower cleaning duster removes material powder adhering to the upper surface of the mixing drum, while the upper cleaning duster removes material powder adhering to the lower surface of the mixing drum lid. The dust collection fan is activated to suck up the dust from inside the upper and lower dust collection hoods. The dust is filtered through a filter box, and the filtered air is discharged through an exhaust pipe. The upper cleaning block wipes the lower surface of the mixing drum lid, and the lower cleaning block wipes the upper surface of the mixing drum, removing any remaining dust. This solves the problem that some of the additives used in mixing with polyamide resin are in powder form. When the mixing device is opened, the suction generated by opening the lid will draw up the powder inside the mixing chamber and lift it up. When the powder falls onto the connection area of ​​the mixing drum, it easily adheres to its surface, thus affecting the sealing effect of the mixing device and causing material leakage during mixing.

[0022] 2. This invention cleans the discharge pipe using a discharge sliding mechanism. First, the telescopic cylinder of the discharge sliding mechanism extends, pushing the upper cover of the discharge sliding mechanism upward. The upper cover of the discharge sliding mechanism drives the second telescopic rod to extend. After the second telescopic rod is fully extended, it pulls the cleaning duster of the discharge sliding mechanism and the upper cover of the discharge sliding mechanism to move synchronously until the first telescopic rod is also fully extended. The discharge telescopic cylinder extends and reciprocates, and the cleaning duster of the discharge sliding mechanism shakes up the dust adsorbed on the inner wall of the discharge pipe. The flying dust eventually falls into the dust collection tank for collection due to gravity. After cleaning is completed, the telescopic cylinder of the discharge sliding mechanism is retracted, which can retract the cleaning duster of the discharge sliding mechanism into the cleaning duster tank of the discharge sliding mechanism. The upper cover of the discharge sliding mechanism is sealed to the fixed seat of the discharge sliding mechanism to prevent material from entering the cleaning duster tank of the discharge sliding mechanism during discharge.

[0039] A method for using a device for uniformly mixing functional additives in polyamide production includes the following steps:

[0040] Step 1: Extend the mixing tank lid and lift the telescopic cylinder 15 to move the mixing tank lid fixing frame 4 upward. As the mixing tank lid fixing frame 4 moves upward, it also moves the mixing tank lid 3 upward, injecting polyamide resin and additives into the interior of the mixing tank 11.

[0041] Step 2: Extend the telescopic cylinder 33 of the dust removal mechanism 12. The telescopic cylinder 33 pushes the dust removal fixed seat 24, allowing the dust removal fixed seat 24 to slide along the dust removal fixed seat slide rail groove 26 to limit the dust removal fixed seat slide rail 27, so that the lower surface of the lower cleaning duster 31 and the lower cleaning block 45 are in contact with the upper surface of the mixing tank 11. Then, retract the telescopic cylinder 15 of the mixing tank cover lifting mechanism to drive the mixing tank cover adjusting seat 5 to move downward, so that the outer side of the lower end of the mixing tank cover adjusting seat 5 is in contact with the upper cleaning duster 29 and the upper cleaning block 44.

[0042] Step 3: Start the dust removal mechanism motor 39. The output end of the dust removal mechanism motor 39 drives the dust removal mechanism gear 40 to rotate. The dust removal mechanism gear 40 meshes with the gear rack 13, thereby driving the dust removal mechanism 12 to slide along the limiting slider groove 42 to limit the limiting slider 14, so that the dust removal mechanism 12 can rotate circumferentially outside the mixing barrel 11. The lower cleaning duster 31 dusts off the material powder adhering to the upper surface of the mixing barrel 11, and the upper cleaning duster 29 dusts off the material powder adhering to the lower surface of the mixing barrel cover 3, thus starting the dust collection. The blower 34 will suck up the dust kicked up inside the upper dust collection hood 30 and the lower dust collection hood 32, filter the dust through the filter box 36, and discharge the filtered air through the air outlet pipe 35. The upper cleaning block 44 wipes the lower surface of the mixing tank cover 3, and the lower cleaning block 45 wipes the upper surface of the mixing tank 11 to remove the remaining dust. After cleaning, the dust cleaning fixing seat telescopic cylinder 33 is retracted to reset the dust cleaning fixing seat 24, and then the mixing tank cover lifting telescopic cylinder 15 is retracted to make the mixing tank cover 3 and the mixing tank 11 fit together.

[0043] Step 4: Start the mixing motor 19. The output of the mixing motor 19 drives the drive pulley 20 to rotate. The drive pulley 20 drives the driven pulley 21 to rotate via the belt. The driven pulley 21 drives the mixing roller 22 to rotate. The rotating mixing roller 22 drives the stirring paddle 18 to rotate, thereby mixing and stirring the materials.

[0044] Step 5: After mixing is completed, control the discharge telescopic cylinder 9 to retract. The discharge telescopic cylinder 9 drives the unloading sliding mechanism 17 to slide downward, so that the material enters the discharge pipe 8 and is finally discharged through the discharge pipe 10.

[0045] Working principle: After unloading, the discharge pipe 8 is cleaned by the unloading sliding mechanism 17. First, the telescopic cylinder 53 of the unloading sliding mechanism extends, which pushes the upper cover 49 of the unloading sliding mechanism to move upward. The upper cover 49 of the unloading sliding mechanism drives the second telescopic rod 50 to extend. After the second telescopic rod 50 is fully extended, it pulls the cleaning duster 48 of the unloading sliding mechanism and the upper cover 49 of the unloading sliding mechanism to move synchronously until the first telescopic rod 52 is also fully extended. The discharge telescopic cylinder 9 extends and reciprocates. The cleaning duster 48 of the unloading sliding mechanism shakes up the dust adsorbed on the inner wall of the discharge pipe 8. The flying dust eventually falls into the dust collection tank 51 for collection due to gravity. After cleaning is completed, the telescopic cylinder 53 of the unloading sliding mechanism is retracted to return the cleaning duster 48 of the unloading sliding mechanism to the cleaning duster tank 47 of the unloading sliding mechanism. The upper cover 49 of the unloading sliding mechanism is sealed to the fixing seat 46 of the unloading sliding mechanism to prevent material from entering the cleaning duster tank 47 of the unloading sliding mechanism during unloading.
