Description

Technical Field

[0001] The invention relates to the technical field of ABS plastic particle production test, in particular to a continuous feeding device with anti-caking function for producing ABS plastic particles. Background Art

[0002] ABS plastic is a ternary copolymer of acrylonitrile (A), butadiene (B), and styrene (S). The relative content of the three monomers can be changed arbitrarily to make various resins. ABS plastic has the common properties of the three components. A makes it resistant to chemical corrosion and heat, and has a certain surface hardness, B makes it highly elastic and tough, and S makes it have the processing and molding characteristics of thermoplastics and improves electrical properties. Therefore, ABS plastic is a "tough, hard, and rigid" material with easy-to-obtain raw materials, good comprehensive properties, low price, and a wide range of uses. ABS plastic has been widely used in manufacturing industries such as machinery, electrical, textile, automobile, aircraft, and shipbuilding, as well as chemical industry. The existing ABS plastic granule processing extruder equipment needs to be heated and melted during operation, so the screw length-to-diameter ratio of the extruder is usually relatively high, with L / D between 18 and 22, a compression ratio of (2.5 to 3.0), and barrel temperatures of: 150 to 160°C for the hopper, 180 to 190°C for the front of the barrel, and 185 to 195°C for the die head. The ABS plastic filaments are not completely cooled by supercooled water and then enter the granulator. The ABS material has a certain degree of brittleness after being completely cooled. The specific process is to enter the granulator with a certain temperature for granulation to avoid particle breakage, and finally dehumidify and cool for packaging.

[0003] In the production process of ABS plastic particles, ABS plastic particles need to be kept dry to avoid agglomeration and adhesion. The amount used is small and the precision requirement is high. However, existing feeders often use intermittent feeding, which causes problems such as discontinuous feeding. In the feeding process, ABS plastic particles are easily agglomerated and adhered due to extrusion or increased viscosity of ABS plastic particles due to heat, which leads to fluctuations in feeding amount and affects production precision. Therefore, it is necessary to design a continuous feeding device with anti-caking for the production of ABS plastic particles with strong practicality, continuity and uniformity of small-dose feeding.

During the feeding process, the air pump 5 is started so that the input end of the air pump 5 sucks the gas inside the external air supply device, and then discharges it into the particle mixing tube 2 through the air supply pipe 4. After the airflow enters the particle mixing tube 2, it will be dispersed by the orifice plate 10 and then blown upward evenly. Part of the airflow is blown to the guide plate 12 through the exhaust pipe 11 and then guided to the upper surface of the orifice plate 10 by the guide plate 12. The airflow entrains the ABS plastic particles entering the particle mixing tube 2 to form a particle mixture that enters the feeding pipe 3, and then is discharged to the ABS plastic particle production test equipment, thereby realizing the feeding operation of the dehumidification test equipment. In addition, since the ABS plastic particles are entrained by the airflow during the feeding process, the ABS plastic particles can be prevented from adhering to the feeding port of the production equipment to cause blockage; The feeding mechanism 8 includes a fixed bin 801, the left side of the fixed bin 801 is fixedly connected to the right side of the outer wall of the particle mixing tube 2, an opening is provided on the left side of the fixed bin 801, and the opening on the left side of the fixed bin 801 is connected to the feeding port on the right side of the particle mixing tube 2, a connecting cover 802 is fixedly connected to the upper side of the fixed bin 801, a sealing cover 803 is threadedly connected to the upper side of the connecting cover 802, a curved pipe 804 is fixedly connected to the middle part of the sealing cover 803, a first motor 805 is fixedly connected to the lower side of the outer wall of the fixed bin 801, a counterweight 806 is fixedly connected to the output end of the first motor 805, a second motor 807 and a reducer 808 are fixedly connected to the lower side of the fixed bin 801, an input end of the reducer 808 is fixedly connected to a first transmission rod 809, an output end of the second motor 807 is transmission-connected to the outer wall of the first transmission rod 809 through a gear and a transmission belt, and an output end of the reducer 808 is fixedly connected to a second transmission rod 810, The front side of the outer wall of the bin 801 is rotatably connected with a third transmission rod 811 through a bearing, the outer wall of the second transmission rod 810 is transmission-connected to the outer wall of the third transmission rod 811 through a gear and a transmission belt, a crushing mechanism 812 is provided on the left side of the third transmission rod 811, a fourth transmission rod 813 is provided on the fixed bin 801, the front and rear ends of the fourth transmission rod 813 pass through the fixed bin 801, the outer wall of the fourth transmission rod 813 is rotationally connected to the inner wall of the fixed bin 801 through a bearing, the outer wall of the fourth transmission rod 813 is transmission-connected to the outer wall of the second transmission rod 810 through a gear and a transmission belt, the outer wall of the fourth transmission rod 813 is fixedly connected with a transmission roller 814, two transmission rollers 814 are provided, both ends of the left transmission roller 814 are rotationally connected to the inner wall of the fixed bin 801 through a bearing, the outer walls of the two transmission rollers 814 are sleeved with a transmission belt 815, and the left side of the transmission belt 815 extends to the inside of the particle mixing tube 2 through the feed port; Before feeding into the particle mixing tube 2, first open the cover 803, then pour the prepared amount of ABS plastic particles into the fixed bin 801, so that the ABS plastic particles are laid on the upper side of the transmission belt 815, and then start the first motor 805 to drive the counterweight block 806 to rotate. Since the counterweight block 806 is unevenly weighted, the center of gravity position changes continuously during the rotation process, which can drive the feeding mechanism 8 and the particle mixing tube 2 to vibrate under the support of the first spring 7. Since the outer wall of the transmission belt 815 is in close contact with the inner wall of the fixed bin 801, the ABS plastic particles on the upper side of the transmission belt 815 will be evenly distributed during the vibration. The upper surface of the transmission belt 815 is then turned off, and the second motor 807 is started to feed. The second motor 807 drives the first transmission rod 809 to rotate, and the reducer 808 drives the second transmission rod 810 to rotate at a slow speed, so that the second transmission rod 810 drives the fourth transmission rod 813 to drive the transmission belt 815 to move slowly through the transmission of the gear and the transmission belt, so that the ABS plastic particles can be evenly and slowly fed into the particle mixing tube 2 within the production time, thereby ensuring the stability of the ABS plastic particle content in the airflow, so as to avoid a large error in the feeding amount during the feeding process of the ABS plastic particle production test device; The crushing mechanism 812 includes a rotating gear 201, the outer wall of the rotating gear 201 is connected to the outer wall of the third transmission rod 811 through gear transmission, a displacement hole penetrating front and rear is opened on the fixed bin 801 at the upper left part of the transmission belt 815, the outer wall of the fixed bin 801 is located at the outer side of the front part of the displacement hole and is rotatably connected to the outer wall of the rotating gear 201 through a bearing, the inner wall of the rotating gear 201 is slidably connected to a moving rod 202, the rear end of the moving rod 202 passes through the displacement hole and moves to the rear side of the fixed bin 801, the front side of the outer wall of the moving rod 202 is fixedly connected to a second spring 203, the front end of the second spring 203 is fixedly connected to the inner wall of the rotating gear 201, the middle part of the outer wall of the moving rod 202 is fixedly connected to a sealing roller 204, the inner wall of the moving rod 202 is fixedly connected to an electric heating pipe 205, the lower The side contacts with the upper side of the outer wall of the transmission belt 815, the outer wall of the sealing roller 204 contacts with the inner wall of the displacement hole, the outer wall of the moving rod 202 located at the outer side of the rear side of the fixed bin 801 is fixedly connected with a second protrusion 207, and the front side of the second protrusion 207 is provided with a first protrusion 206, the front side of the outer wall of the first protrusion 206 is fixedly connected with the rear side of the outer wall of the fixed bin 801, the front side of the outer wall of the second protrusion 207 contacts with the rear side of the outer wall of the first protrusion 206, and the lower side thickness of the first protrusion 206 is greater than the upper side thickness of the first protrusion 206, and the lower side thickness of the second protrusion 207 is less than the upper side thickness of the second protrusion 207, the upper side opening of the curved pipe 804 is set downward, and the inner wall of the upper side opening of the curved pipe 804 is fixedly connected with a whistle 816, and the curved pipe 804 connects the inside of the connecting cover 802 with the outside of the connecting cover 802; During the feeding process, the sealing roller 204 separates the interior of the particle mixing tube 2 from the interior of the fixed bin 801 to prevent the airflow from affecting the ABS plastic particles in the fixed bin 801. During the feeding process of the transmission belt 815, the second transmission rod 810 drives the third transmission rod 811 to rotate, and then the third transmission rod 811 drives the rotating gear 201 to rotate, so that the rotating gear 201 drives the moving rod 202 and the sealing roller 204 to rotate. In the process of the rotating rod 202, when the thicker side of the second protrusion 207 rotates to the lower side, The first protrusion 206 pushes the moving rod 202 and the sealing roller 204 to move rightward, and then when the thicker side of the second protrusion 207 moves to the upper side, the sealing roller 204 and the moving rod 202 are pulled back to their original positions by the elastic force of the second spring 203. Therefore, the sealing roller 204 will move slightly in the front-to-back direction during its rotation. When the ABS plastic particles pass the lower side of the sealing roller 204, the sealing roller 204 will grind the agglomerated particles inside the ABS plastic particles apart, thereby avoiding the existence of particles inside the ABS plastic particles and making the feeding process more uniform. When the first motor 805 rotates to vibrate the fixed bin 801, the larger particles inside the ABS plastic particles are vibrated and moved to the upper layer of the ABS plastic particles, making it easier to be ground by the sealing roller 204. The electric heating tube 205 heats the moving rod 202 and the sealing roller 204, so that the ABS plastic particles are heated when passing through the sealing roller 204, thereby making them drier and avoiding agglomeration. The dehumidified ABS plastic particles can reduce the uneven dehumidification inside and outside when dehumidifying. The extrusion mechanism 9 includes a connection hole 901, which is a hole that connects the upper side of the particle mixing tube 2 with the interior of the particle mixing tube 2. The extrusion mechanism 9 also includes a third motor 902. The outer wall of the third motor 902 is fixedly connected to the upper side of the particle mixing tube 2. The output end of the third motor 902 is fixedly connected to a first bevel gear 903. The lower side of the first bevel gear 903 is meshed with a second bevel gear 904. The lower side of the outer wall of the second bevel gear 904 is rotatably connected to the upper surface of the particle mixing tube 2 through a bearing. The second bevel gear 904 is rotatably connected to the upper surface of the particle mixing tube 2 through a bearing. The inner wall of 04 is threadedly connected with a threaded column 905, the lower end of the threaded column 905 penetrates the particle mixing tube 2 and extends to the inside of the particle mixing tube 2, the outer wall of the threaded column 905 is slidably connected to the inner wall of the particle mixing tube 2, and a sealing plate 907 is provided at the lower end of the threaded column 905, the upper side of the sealing plate 907 contacts the upper side of the inner wall of the particle mixing tube 2, and a spring groove is provided on the lower side of the threaded column 905, and the upper side of the inner wall of the spring groove is fixedly connected with a third spring 906, and the lower end of the third spring 906 is fixedly connected to the upper side of the outer wall of the sealing plate 907; At the feeding tail stage of a general powder blowing feeding device, since the feeding of ABS plastic particles is finished, the content of ABS plastic particles remaining in the airflow will gradually decrease in the airflow, thus causing fluctuations in the feeding amount at the tail stage. After the feeding inside the feeding mechanism 8 of the present device is finished, the third motor 902 can be started to drive the first bevel gear 903 to rotate, and then the first bevel gear 903 drives the second bevel gear 904 to rotate. Since the inner wall of the second bevel gear 904 is threadedly connected with the outer wall of the threaded column 905, and the threaded column 905 cannot rotate due to the sliding connection with the inner wall of the particle mixing tube 2, the threaded column 905 drives the sealing plate 907 to move downward, so that the internal space of the particle mixing tube 2 is compressed, and then the airflow can discharge the ABS plastic particles remaining in the particle mixing tube 2 faster, thereby reducing the fluctuation of the feeding amount caused by the tail stage and avoiding the residual ABS plastic particles in the particle mixing tube 2. During the vibration spreading process of the feeding mechanism 8, the vibration of the particle mixing tube 2 will cause the sealing plate 907 to vibrate up and down under the suspension of the third spring 906. At this time, the up and down movement of the sealing plate 907 will cause the internal air pressure of the particle mixing tube 2 to change. At this time, it is possible to observe whether the whistle 816 makes a sound to determine whether the change in the internal air pressure of the particle mixing tube 2 affects the interior of the fixed bin 801, thereby ensuring the relative isolation between the fixed bin 801 and the interior of the particle mixing tube 2, thereby ensuring uniform and smooth feeding.
