Description

Technical Field

[0001] The present application relates to the technical field of color mixers, and in particular to a vertical color mixer for molding masterbatches. Background Art

[0002] In the process of making plastic particles, generally multiple processes are required, and coloring the plastic particles is a necessary process. The vertical color mixer uses the vortex-type high-speed operation of the material-dispensing blades to make the plastic particles roll, collide, rub and heat at high speed, so as to mix the materials. The color mixer has a reasonable structure and is easy to operate.

[0003] The existing patent (Announcement No.: CN220198176U) discloses a vertical color mixer for uniformly mixing plastic particles, including a shell, a sealing ring is movably connected to the top of the inner side of the shell, a top cover is fixedly connected to the upper surface of the sealing ring, and a motor is fixedly connected to the middle of the upper surface of the top cover. The vertical color mixer for uniformly mixing plastic particles is provided with a motor, a rotating rod, a crushing knife, a stirring blade, a scraper and a spiral conveying blade. The motor drives the rotating rod to rotate, and the crushing knife crushes the plastic particles entering the shell to improve the crushing efficiency, make the plastic particles easier to melt, and speed up the color mixing efficiency. The multiple stirring blades improve the stirring effect and make the mutual movement between the plastic particles more sufficient. The scraper scrapes off the material adhered to the inner wall of the shell to avoid material waste and make cleaning more convenient. The spiral conveying blade stirs and dredges the plastic particles inside the discharge pipe to avoid pipe blockage, and the practicality is enhanced.

[0004] The scraper is used to scrape off the material adhered to the inner wall of the shell, thus avoiding material waste and making cleaning more convenient. However, during use, the scraper is in continuous contact with the inner wall of the shell and scrapes the inside of the shell, which not only accelerates the wear intensity of the shell and the scraper, but also causes a gap between the scraper and the shell, making scraping impossible. At the same time, it is easy to generate continuous noise, which is inconvenient to use. Utility Model Content

[0005] In response to the shortcomings of the prior art, the present application provides a vertical color mixer for molding masterbatch, which has the advantages of low wear intensity, etc., and solves the problem of continuous contact between the scraper and the inner wall of the shell, scraping the inside of the shell, which not only accelerates the wear intensity of the shell and the scraper, but also causes a gap between the scraper and the shell, making it impossible to scrape, and is prone to continuous noise, making it inconvenient to use.

[0007] An adjusting rod is slidably inserted inside each adjusting cylinder, three flexible scraping plates arranged in a circle are arranged inside the mixing tank, and two stirring blades are fixedly connected to the outer surface of each adjusting cylinder.

[0008] Through the above scheme, the purpose of mixing materials can be achieved by driving the stirring blades to rotate through the pressure tube, and the electric push rod can be used to drive the piston to move downward, and the two sealing plugs can be pushed by air pressure to drive the flexible scraper plate away from the pressure tube, so that the flexible scraper plate contacts the inner wall of the mixing tank, and the electric push rod is used to drive the piston to reciprocate, so that intermittent contact between the flexible scraper plate and the mixing tank can be achieved, thereby effectively reducing the wear between the two, and the reversal of the pressure tube can lock the auger blades connected by the one-way bearing, thereby realizing the rotation of the auger blades, achieving the purpose of facilitating discharging and avoiding material blockage.

[0009] Furthermore, one end of the adjusting rods in the middle group close to the pressure pipe is fixedly connected with a sealing plug, and each sealing plug is slidably plugged with the adjusting cylinder close to it.

[0010] According to the above scheme, the air tightness inside the pressure tube can be improved by setting the sealing plug.

[0011] Furthermore, each sealing plug is fixedly connected to a spring on one side away from the pressure tube, the other end of each spring is fixedly connected to the inner wall of the regulating tube adjacent to it, and each spring is sleeved with the regulating rod adjacent to it.

[0012] Through the above solution, by setting the spring, power can be provided for resetting the sealing plug.

[0013] Furthermore, one end of the two groups of adjusting rods located at the top and the bottom and close to the pressure pipe is fixedly connected to a limiting disk.

[0014] Through the above solution and the setting of the limit plate, the adjustment rod can be prevented from falling off.

[0015] Furthermore, one side of each flexible scraper plate close to the pressure tube contacts a mounting plate, the mounting plate is connected to the adjacent flexible scraper plate via external bolts, and each adjusting rod is fixedly connected to the adjacent mounting plate.

[0018] Through the above scheme, by setting the electric push rod, it is possible to provide power for the movement of the piston.

[0019] Furthermore, the bottom end of the pressure pipe is rotatably connected to an auger blade via a one-way valve bearing.

[0020] Through the above scheme, by setting the auger blades, it is possible to avoid clogging of the bottom end of the mixing tank.

[0021] Furthermore, a valve body is installed at the bottom end of the mixing tank, and a feed pipe arranged to be inclined upward is fixedly connected to the outer surface of the top end of the mixing tank.

The setting of the limit plate 10 can prevent the adjusting rod 5 from falling off. Three flexible scraping plates 6 arranged in a circle are provided inside the mixing tank 1. One side of each flexible scraping plate 6 close to the pressure tube 2 is in contact with a mounting plate 11. The mounting plate 11 is connected to the flexible scraping plate 6 close to it through external bolts. Each adjusting rod 5 is fixedly connected to the mounting plate 11 close to it.

During the rotation of the pressure tube 2, the adjusting cylinder 4 and the stirring blade 7 are driven to rotate to mix the material. The piston 3 is driven to reciprocate by the electric push rod 12, and the piston 3 moves downward, so that the middle sealing plug 8 is pushed by the air pressure, and then the tension spring 9 drives the adjusting rod 5 away from the pressure tube 2, so that the flexible scraper plate 6 contacts the inner wall of the mixing tank 1 and scrapes the inner wall. The piston 3 moves upward, and the flexible scraper plate 6 is reset under the reset of the spring 9. During the scraping process, the wear intensity of the flexible scraper plate 6 is effectively reduced.
