Description

Technical Field

[0001] The present invention relates to the technical field of antistatic agent manufacturing, and particularly to a preparation device and a preparation method for a novel antistatic agent. Background Art

[0002] Any object has its own static charge, which can be negative or positive. The accumulation of static charge affects or even endangers life or industrial production. Chemicals that guide and eliminate the accumulated harmful charge so that it does not cause inconvenience or harm to production and life are called antistatic agents. Antistatic agents are additives added to plastics or coated on the surface of molded products to reduce the accumulation of static electricity. Generally, according to different usage methods, antistatic agents can be divided into two major categories: internal addition type and external coating type. The main ones used in plastics are internal addition type antistatic agents, and they can also be divided into two major categories: temporary and permanent according to the performance of antistatic agents.

[0003] An antistatic agent particle manufacturing device with the application number 202022796246.8, which relates to the technical field of antistatic agent manufacturing, includes a box body. A fixing plate is fixedly connected inside the box body. An electric motor mounting plate is fixedly connected inside the box body below the fixing plate. A funnel is fixedly connected to the top of the box body. A granulation mechanism is arranged inside the fixing plate. A screening mechanism is arranged inside the box body below the granulation mechanism. The granulation mechanism includes a rotating tube. The rotating tube is arranged below the funnel, penetrates through the fixing plate and is rotatably connected to the fixing plate. A first gear is fixedly connected to the side end of the rotating tube above the fixing plate. When in use, the antistatic agent is granulated by setting a rotating block, a rotating tube, and a fixing rod. The rotating block and the rotating tube are controlled to rotate in opposite directions by setting an electric motor, a first helical gear, a second helical gear, and a third helical gear. Screening is carried out by setting a sieve plate. This device has simple operation, perfect functions, and strong practicability.

[0004] Although the above technical solution solves the screening work of the antistatic agent, during the production and forming process of the antistatic agent, since debris will be generated during the granulation of the antistatic agent, and during the screening of the cut antistatic agent, the heat generated by the machine operation cannot be controlled, and the antistatic agent is not sufficiently cooled, which increases the instability of the antistatic agent cooling, resulting in the problem that the antistatic agent is not sufficiently cooled and a large amount of heat accumulates in the particles, causing the particles to soften and stick together, affecting the product quality.

[0005] Therefore, it is very necessary to solve the above problems through a preparation device and a preparation method for a novel antistatic agent. Summary of the Invention

[0018] A preparation method of a preparation device for a novel antistatic agent is as follows:

[0019] S1. First, the well-stirred and mixed antistatic agent and carrier resin are conveyed into the forming assembly.

[0020] S2. Second, the forming assembly extrudes the material and cuts it into granular form through the cutting component. Meanwhile, a protection component is arranged outside the cutting component to prevent the cut antistatic agent particles from splashing and causing waste of raw materials.

[0021] S3. Then, the cut antistatic agent particles enter the lower cooling and screening assembly through the protection component.

[0022] S4. Finally, the antistatic agent particles are cooled and screened through the cooling and screening assembly to complete the preparation of the antistatic agent, and prevent the cut antistatic agent particles from sticking together and affecting the product quality.

[0023] Technical effects and advantages of the present invention:

[0024] 1. The present invention cools and screens the antistatic agent after granulation through a cooling and screening assembly. The granulated antistatic agent enters the cooling and screening assembly from the discharge hopper. The second cooling fan sprays cold air from the air jet head through the air duct to perform secondary cooling on the antistatic agent. At the same time, the wind speed of the cold air sprayed from the air jet head accelerates the falling speed of the antistatic agent, making the lighter antistatic agent debris fall faster, entering the adjustment assembly earlier than the standard antistatic agent particles, realizing the preliminary separation of the antistatic agent particles and debris. At the same time, it intensifies the collision between the antistatic agent and the stirring blades on the stirring frame, breaking up the antistatic agent particles that are stuck together, facilitating subsequent screening.

[0025] 2. The controller of the present invention energizes the electromagnetic ring, causing the electromagnetic ring to generate a magnetic force to upwardly extrude the spring and adsorb the outer housing. After reaching the set value, the electromagnetic ring is de-energized. When the spring loses the extrusion force, it pushes the electromagnetic ring under its own elastic force to drive the first screening cylinder to return to the initial state. By controlling the electromagnetic ring to be periodically energized and de-energized by the controller, the first screening cylinder always moves up and down reciprocally, so that the antistatic agent falling into the first screening cylinder vibrates. According to different masses, the vibration frequencies are different, causing the debris and particles to separate and be discharged from the first screening holes. At the same time, the qualified antistatic agent particles are discharged from the second screening holes and enter the second screening cylinder for secondary screening, avoiding the problem that the residual debris in the antistatic agent affects the overall quality of the product.

[0026] 3. The present invention, by setting a rotating assembly, the controller controls the electric telescopic rod to extend. The electric telescopic rod pushes out the rotating plate, the cleaning brush and the electromagnetic locking ring through the push plate. When the upper surface of the push plate is parallel to the inner surface of the bottom of the first screening cylinder, the movement stops. Then the controller energizes the electromagnetic locking ring to lock the electromagnetic locking ring with the central axis of the stirring frame, so that the electromagnetic locking ring, the rotating plate and the cleaning brush rotate along with the stirring frame. The cleaning brush clears the debris adhering to the first screening holes, and at the same time, the rotating plate breaks up the antistatic agent that is bonded together. The stirring of the rotating plate speeds up the screening rate of the antistatic agent and the heat dissipation rate of the antistatic agent, avoiding the problem that a large amount of antistatic agent accumulates and the internal heat cannot be dissipated.

[0039] 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.

[0040] The first embodiment

[0041] The present invention provides, as Figures 1 to 11 shown, a preparation device for a new type of antistatic agent, including a forming assembly 1, a protection assembly 2, a cutting assembly 3, a cooling and screening assembly 4, a rotating assembly 5, a first mounting bracket 6, and a second mounting bracket 7. The forming assembly 1 is arranged on the upper side of the first mounting bracket 6. The cutting assembly 3 is arranged outside the discharge port of the forming assembly 1. The protection assembly 2 is arranged outside the cutting assembly 3. The cooling and screening assembly 4 is arranged under the protection assembly 2 and on the upper side of the second mounting bracket 7. The rotating assembly 5 is arranged inside the cooling and screening assembly 4.

[0042] As Figure 1 and Figure 3 shown, the forming assembly 1 includes a feed hopper 101. A lower side of the feed hopper 101 is fixedly provided with an extrusion barrel 102. One end of the extrusion barrel 102 close to the protection assembly 2 is fixedly provided with an extrusion plate 104. Extrusion holes 105 are formed inside the extrusion plate 104. A spiral feeding rod 103 is movably arranged inside the extrusion barrel 102. The lower side of the extrusion barrel 102 is fixedly connected to the first mounting bracket 6. On the upper surface of the first mounting bracket 6, on a side far from the extrusion barrel 102, a first driving motor 106 is fixedly provided. One end of the spiral feeding rod 103 far from the extrusion plate 104 and an output shaft end of the first driving motor 106 are both fixedly provided with first belt pulleys 107, and a transmission belt is arranged between the two first belt pulleys 107.

[0043] During specific implementation, in the production process, the uniformly stirred antistatic agent raw materials enter the extrusion barrel 102 through the feed hopper 101 in the previous process. At the same time, the controller controls the first driving motor 106 to drive the spiral feeding rod 103 to rotate through the first belt pulley 107 and the belt. The spiral feeding rod 103 conveys the antistatic agent raw materials to the extrusion plate 104. As the spiral feeding rod 103 rotates, the antistatic agent raw materials are extruded from the extrusion holes 105 on the extrusion plate 104, and then the extruded antistatic agent raw materials are cut into particles by the cutting assembly 3.

[0044] As Figure 2As shown, the protection component 2 includes a protective cover 201. A discharge hopper 203 is hinged to the lower surface of the protective cover 201. A suction fan 202 is fixedly arranged at the top of the protective cover 201. First coolers 204 are fixedly arranged on both side walls of the discharge hopper 203. A mounting plate 205 is fixedly arranged on the side of the discharge hopper 203 away from the forming component 1.

[0045] During specific implementation, during the process of cutting the antistatic agent raw material into pellets, the protective cover 201 and the discharge hopper 203 are closed, avoiding waste of raw materials or injury to others caused by the splashing of antistatic agent particles during the cutting process. At the same time, a suction fan 202 is arranged on the upper side of the protective cover 201 to extract the heat generated during the operation of the forming component 1 and the cutting component 3 through the suction fan 202. Meanwhile, the controller controls the first coolers 204 on both sides of the discharge hopper 203 to cool the cut antistatic agent pellets, avoiding the antistatic agent from sticking together and affecting the product quality.

[0046] As Figure 4 As shown, the cutting component 3 includes a cutting knife shaft 301. A cutting knife holder 302 is connected to the outside of the cutting knife shaft 301 through bearings. A knife rod 303 is fixedly arranged on the outer wall of the cutting knife holder 302. The number of knife rods 303 is multiple, and the multiple knife rods 303 are evenly distributed on the outside of the cutting knife holder 302. Cutting knives 304 are fixedly arranged on the multiple knife rods 303. A transmission sleeve rod 305 is fixedly arranged on the side of the cutting knife holder 302 away from the cutting knife shaft 301. A second driving motor 306 is fixedly arranged at one end of the transmission sleeve rod 305 away from the cutting knife holder 302. The second driving motor 306 is fixedly installed on the mounting plate 205.

[0047] During specific implementation, the cutting component 3 is fixedly connected to the forming component 1 through the cutting knife shaft 301, that is, one end of the cutting knife shaft 301 away from the cutting knife holder 302 is threadedly connected to the threaded hole at the center position of the extrusion plate 104. When the antistatic agent raw material is extruded from the extrusion holes 105 on the extrusion plate 104, the controller controls the second driving motor 306 to drive the cutting knife holder 302 to rotate through the transmission sleeve rod 305. At the same time, the cutting knife holder 302 drives the cutting knives 304 to rotate through the knife rods 303, thereby cutting the extruded antistatic agent into pellets, and the cutting edge of the cutting knife 304 is tangent to the surface of the extrusion plate 104 at an angle of 30 degrees.

[0048] As Figure 5As shown in the figure, the cooling and screening assembly 4 includes a housing 401. Inside the housing 401, a first screening cylinder 4061 is provided. On the side of the interior of the housing 401 away from the first screening cylinder 4061, a second screening cylinder 408 is fixedly arranged. The bottom plate of the first screening cylinder 4061 and the second screening cylinder 408 are both provided with first screening holes 4062. The side cylinder wall of the first screening cylinder 4061 is provided with second screening holes 4063. On the side of the inner side wall of the housing 401 away from the second screening cylinder 408, a material guiding sleeve 407 is fixedly arranged. The top of the first screening cylinder 4061 is fixedly provided with a vibration ring. An outer limit ring 4064 is arranged around the outer part of the vibration ring. The upper surface of the vibration ring is fixedly provided with a spring 4065.

[0049] During specific implementation, the cutting component 3 granulates the antistatic agent and then conveys the cut antistatic agent particles to the inside of the cooling and screening assembly 4 through the discharge hopper 203 for screening. The antistatic agent particles enter the inside of the first screening cylinder 4061 through the discharge hopper 203. Since the antistatic agent particles falling to the bottom of the first screening cylinder 4061 generate a certain impact force on the first screening cylinder 4061, the impact force stretches the spring 4065 through the vibration ring at the top of the first screening cylinder 4061. At the same time, the spring 4065 generates an upward pulling force to resist the impact force, causing the spring 4065 to continuously perform reciprocating motion of contraction and stretching, that is, the vibration ring drives the first screening cylinder 4061 to slide up and down within the limit ring 4064, causing the first screening cylinder 4061 to vibrate and strengthening the screening of the antistatic agent particles. During the screening process, the first screening holes 4062 screen out the debris inside the antistatic particles. The antistatic agent particles are discharged from the second screening holes 4063 and enter the second screening cylinder 408 along the material guiding sleeve 407 for secondary screening. The antistatic agent particles that have completed screening are discharged from the discharge pipe, completing the preparation of the antistatic agent.

[0050] Second Embodiment

[0051] During the working process of the first embodiment, it is found that only the first cooling fan 204 inside the protection assembly 2 cannot sufficiently cool the cut antistatic agent, and the heat generated by the cooling and screening assembly 4 during the screening process will also cause the problem that the antistatic agent is not sufficiently cooled or melted, resulting in the adhesion of the antistatic agent and blocking of the screening holes, which is not conducive to the feeding of the antistatic agent. Moreover, the antistatic agent adhered together cannot be scattered and discharged, resulting in a large accumulation of the antistatic agent and affecting the overall production efficiency. To solve the above technical problems, the following modifications are made:

[0052] As Figure 5 、 Figure 6As shown, the cooling and screening assembly 4 includes a housing 401 and an adjustment assembly 406. An air-cooling assembly 404 is fixedly arranged on the upper surface of the housing 401. The outer wall of the bottom side of the housing 401 is fixedly connected to the second mounting bracket 7. A third driving motor 409 is fixedly arranged on the upper surface of the second mounting bracket 7 corresponding to one side of the outer wall of the housing 401. A stirring frame 405 is movably arranged inside the housing 401. Second pulleys 4010 are fixedly arranged at the bottom end of the stirring frame 405 and the output shaft end of the third driving motor 409, and a transmission belt is arranged between the two second pulleys 4010. A second screening cylinder 408 is fixedly arranged on the inner lower surface of the housing 401. A material guiding sleeve 407 is fixedly arranged on the inner side wall of the housing 401 away from the second screening cylinder 408. A group of counting sensors are arranged on the material guiding sleeve 407. The inner top surface of the housing 401 is fixedly connected to the adjustment assembly 406. Two waste outlets 4011 are opened on the bottom side of the housing 401.

[0053] During specific implementation, after the antistatic agent is granulated, it enters the cooling and screening assembly 4 from the discharge hopper 203 for screening. During the falling process, the air-cooling assembly 404 on the upper side of the housing 401 is started to cool the granulated antistatic agent again. At the same time, the controller controls the third driving motor 409 to start. The third driving motor 409 drives the stirring frame 405 to rotate through the second pulley 4010 and the transmission belt. The stirring blades on the stirring frame 405 collide with the falling antistatic agent to break up the antistatic agent that is bonded together, facilitating subsequent full screening by the adjustment assembly 406. The adjustment assembly 406 screens out the debris inside the antistatic agent. At the same time, the qualified antistatic agent is discharged from the adjustment assembly 406 and enters the second screening cylinder 408 through the material guiding sleeve 407 for secondary screening.

[0054] As Figure 8 shown, the air-cooling assembly 404 includes a second cooling fan 4041. An air duct 4042 is fixedly arranged at the air outlet of the second cooling fan 4041. A jet head 4043 is fixedly arranged on the side of the air duct 4042 away from the second cooling fan 4041. The number of jet heads 4043 is multiple, and the multiple jet heads 4043 are evenly distributed on the air duct 4042. The air duct 4042 is opened inside the upper top plate of the housing 401.

[0055] During specific implementation, the antistatic agent that has completed granulation enters the cooling and screening assembly 4 from the discharge hopper 203. Meanwhile, the controller controls the start of the second cooling fan 4041. The second cooling fan 4041 sprays cold air from the air jet head 4043 through the air duct 4042 to perform secondary cooling on the antistatic agent. At the same time, the wind speed of the cold air sprayed by the air jet head 4043 accelerates the falling speed of the antistatic agent, enabling the lighter antistatic agent debris to fall faster and enter the adjustment assembly 406 earlier than the standard antistatic agent particles, achieving preliminary separation of the antistatic agent particles and debris. At the same time, it intensifies the collision between the antistatic agent and the stirring blades on the stirring frame 405, breaking up the antistatic agent particles that are stuck together, facilitating subsequent screening.

[0056] As Figure 7 , Figure 9 shown, the adjustment assembly 406 includes a first screening cylinder 4061. The bottom of the first screening cylinder 4061 is provided with a first screening hole 4062, the side wall of the first screening cylinder 4061 is provided with a second screening hole 4063, the top of the first screening cylinder 4061 is fixedly provided with an electromagnetic ring 4066, a limiting ring 4064 is arranged around the outside of the electromagnetic ring 4066, the upper surface of the electromagnetic ring 4066 is fixedly provided with a spring 4065, and spiral cooling pipes 402 are fixedly arranged inside the barrel walls of the outer housing 401 and the first screening cylinder 4061, and the two spiral cooling pipes 402 are connected by a water pipe. The liquid inlet end of the spiral cooling pipe 402 is fixedly provided with a circulation pump 403, and the liquid outlet end of the spiral cooling pipe 402 is fixedly connected to an external heat exchanger.

[0057] During specific implementation, the antistatic agent processed by the air cooling assembly 404 and the stirring frame 405 enters the first screening cylinder 4061 for preliminary screening. The vibration ring is replaced with an electromagnetic ring 4066, and by adjusting different energization frequencies of the electromagnetic ring 4066, different vibration frequencies of the first screening cylinder 4061 can be adjusted, enhancing the screening effect of the first screening cylinder 4061 on the antistatic agent debris. Meanwhile, the controller controls the circulation pump 403 to replace the coolant in the spiral cooling pipe 402 and the external heat exchanger to cool the entire cooling and screening assembly 4.

[0058] Further, the electromagnetic ring 4066 is energized by the controller, so that the electromagnetic ring 4066 generates magnetic force to squeeze the spring 4065 upward to adsorb the outer housing 401. After reaching the set value, the electromagnetic ring 4066 is powered off. When the spring 4065 loses the extrusion force, under the action of its own elastic force, it pushes the electromagnetic ring 4066 to drive the first screening cylinder 4061 to return to the initial state. The controller controls the electromagnetic ring 4066 to be periodically energized and powered off, so that the first screening cylinder 4061 always moves up and down reciprocally, thereby vibrating the antistatic agent falling into the first screening cylinder 4061. According to different masses, different vibration frequencies cause the debris and particles to separate and be discharged from the first screening holes 4062. At the same time, the qualified antistatic agent particles are discharged from the second screening holes 4063 and enter the second screening cylinder 408 for secondary screening, avoiding the influence of residual debris in the antistatic agent on the overall quality of the product.

[0059] As Figures 10 to 11 shown, the rotating assembly 5 includes an electromagnetic locking ring 501 and a mounting frame 504. A rotating plate 502 is fixedly arranged on the outer side of the electromagnetic locking ring 501. The outer wall of the rotating plate 502 is movably connected to the inner wall of the mounting frame 504. The number of rotating plates 502 is multiple, and the multiple rotating plates 502 are evenly distributed on the outer side of the electromagnetic locking ring 501. Cleaning brushes 503 are fixedly arranged on the lower side of the multiple rotating plates 502 and on one side wall away from the electromagnetic locking ring 501. An electric telescopic rod 505 is fixedly arranged on the inner lower surface of the mounting frame 504. A push plate 506 is fixedly arranged at the telescopic end of the electric telescopic rod 505. The upper surface of the push plate 506 is in contact with the lower surface of the cleaning brush 503.

[0060] During specific implementation, the controller controls the electric telescopic rod 505 to extend. The electric telescopic rod 505 pushes out the rotating plate 502, the cleaning brush 503 and the electromagnetic locking ring 501 together through the push plate 506. When the upper surface of the push plate 506 is parallel to the inner surface of the bottom of the first screening cylinder 4061, the movement stops. Then the controller energizes the electromagnetic locking ring 501 to lock the electromagnetic locking ring 501 with the central axis of the stirring frame 405, so that the electromagnetic locking ring 501, the rotating plate 502 and the cleaning brush 503 rotate along with the stirring frame 405. The cleaning brush 503 cleans the first screening holes 4062, and the rotating plate 502 breaks up the agglomerated antistatic agent.

[0061] Further, a group of counting sensors on the material guiding sleeve 407 count the antistatic agent discharged from the second screening holes 4063. The counting sensors transmit the detected data to the controller in real time for analysis, and the screening situation inside the first screening cylinder 4061 is detected according to the analysis of the data by the controller.

[0062] It should be noted that the counting sensor uses an optoelectronic technology sensor, which consists of an optoelectronic sensor, a small screen and a chip. Its working principle is that when an object passes through the optoelectronic sensor, the optoelectronic sensor generates an electrical signal. After being received and processed by the chip, the counting result is displayed on the small screen. When the antistatic agent particles pass through the counting sensor, they block the optical signal emitted by the optoelectronic sensor, thereby converting the optical signal of the optoelectronic sensor device into an electrical signal. After being processed by the chip, a signal is output, thus realizing the counting of the antistatic agent.

[0063] When the number of antistatic agents discharged detected by the counting sensor is within the preset value, it indicates that the first screening cylinder 4061 is not blocked and the internal antistatic agent is not bonded. When the number of antistatic agents discharged detected by the counting sensor exceeds the preset value, it indicates at this time that the first screening hole 4062 is blocked and debris cannot be discharged from the first screening hole 4062, resulting in a large amount of debris being discharged from the second screening hole 4063. When the value detected by the counting sensor is lower than the preset value, it indicates at this time that the temperature in the first screening cylinder 4061 is too high, causing the debris and antistatic agent particles to melt and bond together, resulting in the antistatic agent not being able to pass through the second screening hole 4063, affecting the production efficiency of the antistatic agent.

[0064] When the number of antistatic agents discharged detected by the counting sensor is higher than the preset value, it indicates that the first screening hole 4062 in the first screening cylinder 4061 is blocked, resulting in a large amount of debris being discharged from the second screening, reducing the screening effect. At this time, the controller controls an increase in the power supply to the electromagnetic ring 4066, causing the magnetic attraction of the electromagnetic ring 4066 to increase and completely compress the spring 4065, and shortening the on-off time interval of the electromagnetic ring 4066, driving the first screening cylinder 4061 to move up and down quickly and significantly, increasing the gas convection generated at the first screening hole 4062, thereby blowing out the debris blocked in the first screening hole 4062 and completing the cleaning of the first screening hole 4062.

[0065] It should be noted that when the counting sensor detects that the number of antistatic agents discharged has returned to within the preset value after the above operations, it indicates at this time that the method of changing the working frequency of the adjusting component 406 to clean the first screening hole 4062 is effective. After the cleaning is completed, the adjusting component 406 returns to the initial frequency for subsequent screening.

[0066] When the counting sensor detects a decrease in the amount of antistatic agent discharged after the above operations but fails to recover to the preset value, it indicates that the method of changing the working frequency of the adjustment component 406 to clean the first screening hole 4062 does not achieve the purpose of completely removing blockages. The debris blocked in the first screening hole 4062 is in a bonded state, and simply relying on the impact of air flow cannot remove it. At this time, the controller controls the electric telescopic rod 505 to push the cleaning brush 503 together with the rotating plate 502 out of the mounting frame 504, and then energizes the electromagnetic locking ring 501 to lock it with the central axis of the stirring frame 405, so that the rotating plate 502 and the cleaning brush 503 rotate together with the stirring frame 405. During the rotation, the bonded debris in the first screening hole 4062 is removed by the cleaning brush 503. At the same time, the cleaning brush 503 also removes the debris adhering to the inner surface of the first screening cylinder 4061, avoiding excessive accumulation of debris and affecting the normal screening of the antistatic agent.

[0067] When the counting sensor detects that the amount of antistatic agent discharged is lower than the preset value, it indicates that the internal temperature of the first screening cylinder 4061 is relatively high due to unstable heat dissipation, resulting in the melting of the debris and the cut surfaces of the antistatic agent particles affected by the temperature of the first screening cylinder 4061 and bonding with the surrounding antistatic agent and being unable to pass through the second screening hole 4063. Moreover, the bonded antistatic agent hinders the surrounding antistatic agent, resulting in the inability of the antistatic agent to be normally screened and accumulating in the first screening cylinder 4061. If not dealt with in time, it will cause the internal temperature to continue to rise, making a large amount of the antistatic agent melt more severely and bond together and be difficult to disperse. At this time, the controller controls the external heat exchanger to lower the temperature of the coolant, and replaces the coolant in the spiral cooling pipe 402 through the circulation pump 403, so as to reduce the overall temperature of the internal environment of the cooling and screening component 4. At the same time, the controller controls the power-on frequency of the electromagnetic ring, thereby increasing the vibration frequency of the first screening cylinder 4061, so as to disperse and separate the bonded antistatic agent and debris. At the same time, through the vibration of the first screening cylinder 4061, the antistatic agent concentrated in the center of the first screening cylinder 4061 is moved to the edge, so that the antistatic agent particles enter the second screening cylinder 408 through the second screening hole 4063, thus achieving the purpose of dispersing the antistatic agent and accelerating the screening, and avoiding the problem of insufficient internal heat dissipation caused by excessive accumulation of the antistatic agent in the first screening cylinder 4061.

[0068] It should be noted that when the heat exchanger lowers the temperature of the coolant, the coolant in the outer shell 401 and the spiral cooling pipe 402 of the first screening cylinder 4061 is circulated and replaced through the circulation pump 403, so that the overall internal temperature of the cooling and screening component 4 is reduced, thereby realizing the cooling of the antistatic agent particles. After cooling, the hardness of the antistatic agent increases, and the melted and bonded part becomes brittle after cooling due to heat absorption. The antistatic agent can be separated from the bonded part by applying an external force.

[0069] Further, if after the above operations, the counting sensor detects that the quantity amplifier of the antistatic agent discharged returns to within the preset value, it indicates that the method of overall cooling the inside of the cooling and screening assembly 4 by reducing the temperature of the coolant and simultaneously increasing the vibration frequency of the first screening cylinder 4061 to disperse the cooled antistatic agent after cooling is effective.

[0070] If after the above operations, the quantity of the antistatic agent detected by the counting sensor increases but does not return to within the preset value, at this time it indicates that increasing the vibration frequency of the first screening cylinder 4061 cannot sufficiently disperse the agglomerated antistatic agent. At this time, the controller controls the electric telescopic rod 505 to extend. The electric telescopic rod 505 pushes out the rotating plate 502, the cleaning brush 503 and the electromagnetic locking ring 501 through the push plate 506. When the upper surface of the push plate 506 is parallel to the inner surface of the bottom of the first screening cylinder 4061, it stops moving. Then the controller energizes the electromagnetic locking ring 501 to lock the electromagnetic locking ring 501 with the central axis of the stirring frame 405, so that the electromagnetic locking ring 501, the rotating plate 502 and the cleaning brush 503 rotate along with the stirring frame 405. The rotation of the rotating plate 502 intensifies the collision between the antistatic agent particles, thereby dispersing the agglomerated antistatic agent. At the same time, the cleaning brush 503 at the bottom removes the antistatic agent adhered to the first screening cylinder 4061. At the same time, the stirring by the rotating plate 502 speeds up the screening rate and the heat dissipation rate of the antistatic agent, avoiding the problem that a large amount of antistatic agent accumulates and the internal heat cannot be dissipated.

[0073] Deionized water, with a mass ratio of 70%;

[0074] Isopropyl alcohol (IPA), with a mass ratio of 20%;

[0075] Ethoxolated Fatty Amine, with a mass ratio of 5%;

[0076] Glycerol monolaurate, with a mass ratio of 2%;

[0077] Polyether modified silicone, with a mass ratio of 2%;

[0078] Sodium citrate, with a mass ratio of 1%.

[0079] During preparation, first, heat deionized water to 40°C and stir, then, sequentially add ethoxylated fatty amine and glycerol monolaurate. Secondly, cool down to 25°C and add isopropyl alcohol and polyether-modified silicone, and continue stirring. Subsequently, add sodium citrate and adjust the pH to 6.5 - 7.5. Finally, filter through a 0.2μm filter membrane and then encapsulate.

[0080] Deionized water is the base solvent, which is environmentally friendly and non-toxic; isopropyl alcohol (IPA) is a fast-drying solvent with a better evaporation rate than ethanol, reducing residues; ethoxylated fatty amine is an environmentally friendly long-acting antistatic agent, reducing surface resistance; glycerol monolaurate is a natural-source moisturizer, synergistically enhancing antistatic performance; polyether-modified silicone is a wetting and spreading agent, improving the coating uniformity; sodium citrate is a pH buffer, enhancing the solution stability.

[0081] When preparing the polyolefin-based antistatic masterbatch, the preparation method is as follows:

[0082] S1. First, convey the well-stirred and mixed antistatic agent and carrier resin into the interior of the molding assembly 1;

[0083] S2. Secondly, the molding assembly 1 extrudes the material, and the cutting assembly 3 cuts it into granules. At the same time, a protective assembly 2 is arranged outside the cutting assembly 3 to prevent the splashing of the cut antistatic agent granules and avoid waste of raw materials;

[0084] S3. Then, the cut antistatic agent granules enter the interior of the lower cooling and screening assembly 4 through the protective assembly 2;

[0085] S4. Finally, cool and screen the antistatic agent granules through the cooling and screening assembly 4 to complete the preparation of the antistatic agent, and prevent the cut antistatic agent granules from sticking together and affecting the product quality.

[0086] It should be noted that the cooling and screening assembly 4 can prevent the masterbatch from sticking or deforming due to high temperature, and at the same time avoid the thermal decomposition of the antistatic agent. The screened masterbatch enters the finished product bin, and the unqualified granules can be returned to the extruder for reprocessing. Package the screened antistatic masterbatch, usually using moisture-proof and antistatic packaging materials.
