[0031] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of a quantitative mixing device for producing plastic particles of the present invention in conjunction with the accompanying drawings.

[0032] See also Figure 1-6 As shown, this embodiment is a quantitative mixing device for producing plastic particles, including a mixing box 100, a first connecting hole 111 is opened at one end of the mixing box 100, a second connecting hole 112 is opened on one side of the first connecting hole 111, a first rotating shaft 210 is installed in the first connecting hole 111, a second rotating shaft 220 is installed in the second connecting hole 112, a first spiral piece 280 is installed on the first rotating shaft 210, and a second spiral piece 290 is installed on the second rotating shaft 220. The first spiral piece 280 and the second spiral piece 290 are installed oppositely on the corresponding rotating shafts, and the first rotating shaft 210 and the second rotating shaft 220 are close to the inner wall of the mixing box 100. A first gear 230 is installed at one end near the first connecting hole 111, and a first chain 240 is installed on the two first gears 230. Two second gears 250 are installed on the first rotating shaft 210 and the second rotating shaft 220 at the end of the mixing lower inner wall away from the first connecting hole 111, and a second chain 260 is installed on the two second gears 250. Two groups of connecting parts 310 are symmetrically installed at the upper and lower ends of the first chain 240 and the second chain 260. A sliding cylinder 320 is installed at the end of any connecting part 310 away from the corresponding gear, and a sliding column 330 is installed in the sliding cylinder 320. A scraper 340 is installed at the end of the sliding column 330 away from the sliding cylinder 320.

[0033] The first rotating shaft 210 and the second rotating shaft 220 are both installed with a first bearing 270 at one end away from the first connecting hole 111, and the end of any first bearing 270 away from the first connecting hole 111 is connected to the inner wall of the mixing box 100. This design can effectively reduce the friction between the first rotating shaft 210 and the second rotating shaft 220.

[0034] A spring 350 is installed at the end of any one of the sliding columns 330 close to the sliding cylinder 320, and the end of any one of the springs 350 away from the sliding column 330 is connected to the end of the connecting piece 310 close to the sliding column 330. This design can push the scraper 340 toward the inner wall through the sliding column 330, so that the scraper 340 is always in contact with the inner wall.

[0035] A pulley 540 is installed at one end of the first rotating shaft 210 away from the first bearing 270, a pulley 530 is installed on one end of the second rotating shaft 220 away from the first bearing 270, a belt 550 is installed between the pulley 530 and the outside of the pulley, a first motor 520 is installed at one end of the second rotating shaft 220 away from the first bearing 270, a mounting base 510 is installed at the lower end of the first motor 520, and the mounting base 510 is connected to one end of the outer wall of the mixing box 100 away from the first bearing 270 close to the end of the first rotating shaft 210. This design can effectively drive the first rotating shaft 210 and the second rotating shaft 220 to rotate.

[0036] Two mounting blocks 460 are installed at the lower end of the mixing box 100, and a second bearing 450 is installed at the opposite end of any one of the mounting blocks 460. A third rotating shaft 440 is installed between the two second bearings 450, and a rotating part 430 is installed on the third rotating shaft 440. A gas rod 420 is installed at the lower end of the rotating part 430, and a cylinder 410 is installed at the end of the gas rod 420 away from the rotating part 430. This design allows the entire device to be tilted toward one end of the discharge pipe 140 when unloading is required, so as to facilitate the unloading of plastic particles.

[0037] Four brackets 160 are installed at the lower end of the mixing box 100, and a discharge hole 113 is opened at the end of the mixing box 100 close to the bracket 160. A discharge pipe 140 is installed at the end of the discharge hole 113 close to the bracket 160, and a discharge valve 150 is installed on the discharge pipe 140; 150, a box cover 120 is installed at the end of the mixing box 100 away from the bracket 160, and two feed pipes 130 are installed on the box cover 120.

[0038] Two mounting brackets 610 are installed at both ends of any one of the feed pipes 130, and a material box 620 is installed between the two mounting brackets 610. A second motor 630 is installed at one end of the material box 620 away from the feed pipe 130, and a transmission shaft 640 is installed at one end of the second motor 630 close to the end of the material box 620. A roller 650 is installed at one end of the transmission shaft 640, and the roller 650 is provided with a connecting hole 660 that passes through the material box 620. The inner diameter of the connecting hole 660 is equal to the inner diameter of the corresponding feed pipe 130. A fixed disk 670 is fixedly installed at one end of the feed pipe 130 away from the box cover 120, and the feed pipe 130 passes through the fixed disk 670. This design is achieved by the second motor 6 30 drives the transmission shaft 640 to rotate, and the transmission shaft 640 drives the roller 650 to rotate. When the connecting hole 660 provided on the roller 650 corresponds to the connecting hole 660 on the material box 620, the plastic particles will enter the connecting hole 660 provided on the roller 650 from the material box 620. Then the roller 650 rotates so that the connecting hole 660 is connected to the feeding pipe 130, and the plastic particles fall into the feeding pipe 130 until they enter the mixing box 100. When the second motor 630 continues to rotate and the connecting hole 660 provided on the roller 650 no longer corresponds to the connecting hole 660 on the material box 620, the feeding is stopped. Since the diameters of the connecting holes 660 provided on the roller 650 are equal, the amount of feeding each time is fixed.

[0039] Working principle: When working, the plastic particles in the material box 620 are first injected into the corresponding feeding pipe 130 through the roller 650, and then the plastic particles that need to be mixed and stirred are poured into the mixing box 100 through the two feeding pipes 130, and then the first motor 520 is started, and the first motor 520 drives the second rotating shaft 220 to rotate. When the second rotating shaft 220 rotates, it drives the pulley 530 to rotate. The pulley 530 then drives the driven wheel 540 to rotate through the belt 550, and the driven wheel 540 in turn drives The first rotating shaft 210 and the second rotating shaft 220 rotate synchronously. The first rotating shaft 210 drives the first spiral piece 280 to rotate when rotating, and drives the plastic particles in the mixing box 100 from the end close to the first connecting hole 111 to the end of the first bearing 270. At the same time, the second rotating shaft 220 drives the second spiral piece 290 to drive the plastic particles from the end close to the first bearing 270 to the end of the first connecting hole 111 when rotating, and the plastic particles are mixed in the mixing process. When the first rotating shaft 210 and the second rotating shaft 220 are engaged, the first chain 240 and the second chain 260 are driven to rotate through the first gear 230 and the second gear 250. The first chain 240 and the second chain 260 drive the connecting member 310 to rotate when rotating. The connecting member 310 drives the sliding column 330 to rotate through the sliding cylinder 320. The sliding column 330 drives the scraper 340 to rotate and drives the plastic particles on the inner wall of the mixing type to move inward, further increasing the mixing efficiency. After completion, the control cylinder 410 pushes out the air rod 420. When the air rod 420 moves outward, it pushes the third rotating shaft 440 outward through the rotating member 430. The third rotating shaft 440 pushes the entire mixing box 100 toward one end of the discharge pipe 140 through the second bearing 450 and the mounting block 460. Then the discharge valve 150 is opened, which will cause the plastic particles to be discharged from the discharge pipe 140. During unloading, the rotation of the internal first spiral blade 280, the second spiral blade 290 and the scraper 340 will accelerate the discharge of the plastic particles.

[0040] It is understood that the present invention is described by way of certain embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
