Description

Technical Field

[0001] The utility model relates to the technical field of internal mixers, in particular to an anti-blocking powder feeding device for a color masterbatch and color sand internal mixer. Background Art

[0002] In the production process of color masterbatch and color sand, as a key mixing equipment, the performance of the internal mixer directly affects the product quality and production efficiency. At present, the existing color masterbatch and color sand internal mixers on the market generally have the problem of powder feeding blockage during the feeding process. These existing technical solutions usually adopt a single feeding port design and lack effective anti-blocking measures, resulting in the feeding port being easily blocked when the feeding volume is large or the material fluidity is poor, thereby affecting the continuity and stability of production.

[0003] To solve the above problems, we propose an anti-blocking powder feeding device for a color masterbatch and color sand internal mixer. This device prevents material blockage by setting two feeding ports to supply materials intermittently and alternately. Content of the Utility Model

[0004] In order to overcome the shortcoming of powder feeding blockage during the feeding process of the internal mixer, the utility model provides an anti-blocking powder feeding device for a color masterbatch and color sand internal mixer.

[0005] The technical solution of the utility model is as follows: an anti-blocking powder feeding device for a color masterbatch and color sand internal mixer, which includes an internal mixer body, and also includes a powder feeding frame. Horizontally symmetrical powder feeding frames are fixedly connected to the internal mixer body. A storage frame is fixedly connected to the powder feeding frame. A baffle is slidably connected to the storage frame. A servo motor is fixedly connected to the top end of the storage frame. A cam is fixedly connected to the output shaft of the servo motor. The cam is in extrusion fit with the baffle. A guide rod is fixedly connected to the top end of the storage frame. A slider is slidably connected to the guide rod. The slider is connected to the baffle. An elastic member is connected between the slider and the guide rod.

[0006] Further, a powder feeding port is communicated with the storage frame.

[0007] Further, it also includes a connecting frame. The connecting frame is rotatably connected to the baffle. A scraper is slidably connected to the inner bottom end of the storage frame. The scraper is rotatably connected to the connecting frame.

[0008] Further, the bottom end of the scraper is serrated.

[0009] Further, it also includes a sieve. The sieve is slidably connected to the inside of the storage frame. A fixing frame is fixedly connected to the sieve. A push plate is fixedly connected to the slider. The push plate extends into the storage frame and is in extrusion fit with the fixing frame.

[0010] Further, it also includes a cleaning plate. The cleaning plate is slidably connected to the internal mixer body.

[0011] The utility model has the following advantages: 1. The rotation of the cam is cooperated with the extrusion of the baffle plate, so as to control the opening of the baffle plate to supply materials to the internal mixer body through the storage bin. By controlling the intermittent staggered opening and closing of the left and right baffle plates, the left and right powder feeding frames can alternately supply materials to the internal mixer body, ensuring the continuity of feeding and avoiding blockage caused by a large amount of feeding.

[0012] 2. When the scraper slides left and right, it can push the powder at the bottom of the storage bin, preventing the powder from staying inside the storage bin and affecting the feeding.

[0013] 3. The powder introduced into the storage bin is filtered through a sieve. Large particle impurities are blocked by the sieve, and the cooperation between the push plate and the fixed frame can drive the sieve to vibrate to improve the filtering effect.

[0014] 4. The cleaning plate can clean the scattered powder at the feeding port of the internal mixer body when it slides back and forth. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solution of the utility model will be further described below in conjunction with the drawings.

[0021] Embodiment 1: A powder feeding anti-blocking device for a color masterbatch and color sand internal mixer, as shown in Figure 1 and Figure 2As shown in the figure, it includes a kneader body 1, a powder inlet frame 101, a storage frame 2, a baffle 3, a servo motor 4, a cam 41, a guide rod 5, a slider 6 and an elastic member 7. In the middle of the kneader body 1, there are symmetrically fixed left and right powder inlet frames 101. A storage frame 2 is fixedly connected to the powder inlet frame 101. The upper part outside the storage frame 2 is communicated with a powder inlet. A baffle 3 is slidably connected inside the storage frame 2. A servo motor 4 is fixedly connected to the upper side of the storage frame 2. A cam 41 is fixedly connected to the output shaft of the servo motor 4. The cam 41 is in extrusion fit with the baffle 3. A guide rod 5 is fixedly connected to the upper side of the storage frame 2. A slider 6 is slidably connected to the guide rod 5. The slider 6 is connected to the baffle 3. An elastic member 7 is connected between the slider 6 and the guide rod 5.

[0022] When using this device, the powder is introduced into the storage frame 2 through the powder inlet. Then the staff controls the operation of the servo motor 4. The rotation of the output shaft of the servo motor 4 drives the rotation of the cam 41. The rotation of the cam 41 squeezes the baffle 3 to slide upward. The upward sliding of the baffle 3 drives the slider 6 to slide upward, and the elastic member 7 deforms. The upward sliding of the baffle 3 opens the storage frame 2, and the powder in the storage frame 2 can be introduced into the kneader body 1 through the powder inlet frame 101. When the cam 41 rotates to no longer squeeze the baffle 3, under the action of the reset of the elastic member 7, the slider 6 drives the baffle 3 to rotate downward to close, and the storage frame 2 stops feeding the powder inlet frame 101. By controlling the intermittent staggered opening and closing of the left and right baffles 3, the left and right powder inlet frames 101 can alternately feed the kneader body 1, ensuring the continuity of feeding and avoiding blockage caused by a large amount of feeding.

[0023] Embodiment 2: On the basis of Embodiment 1, as Figure 3 shown, it further includes a connecting frame 8 and a scraper 9. The lower part of the baffle 3 is rotatably connected with a connecting frame 8. A scraper 9 is slidably connected to the lower part inside the storage frame 2. The scraper 9 is rotatably connected to the connecting frame 8. The lower side of the scraper 9 is serrated.

[0024] When using this device, the up and down sliding of the baffle 3 can drive the left and right sliding of the scraper 9 through the connecting frame 8. When the scraper 9 slides left and right, it can push the powder at the bottom of the storage frame 2, avoiding the powder staying and blocking inside the storage frame 2 and affecting the feeding. And because the lower side of the scraper 9 is serrated, it can prevent the scraper 9 from pushing all the powder inward.

[0025] As Figure 4 shown, it further includes a sieve 10, a fixing frame 11 and a push plate 12. A sieve 10 is slidably connected to the middle part inside the storage frame 2. A fixing frame 11 is fixedly connected to the sieve 10. A push plate 12 is fixedly connected to the slider 6. The lower part of the push plate 12 extends into the storage frame 2 and is in extrusion fit with the fixing frame 11.

[0026] When using this device, the powder material imported into the storage bin 2 is filtered through the screen 10. Large-particle impurities are blocked by the screen 10. When the slider 6 slides up and down, the push plate 12 also moves up and down in cooperation with the fixed frame 11, thereby driving the screen 10 to vibrate up and down to improve the filtering effect.

[0027] As Figure 1 shown, it further includes a cleaning plate 13, and the cleaning plate 13 is slidably connected to the middle of the internal mixer body 1.

[0028] When using this device, the staff can push the cleaning plate 13 to slide back and forth, and the back-and-forth sliding of the cleaning plate 13 can clean the powder material scattered at the feed inlet of the internal mixer body 1.
