[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0022] Example 1

[0023] A quantitative delivery device, referring to Figure 1 and Figure 2 The machine comprises a base 1, on which is mounted a vertically arranged cylindrical metering bin 2. The metering bin 2 has a feed port 2a and a discharge port 2b, respectively, provided with a feed valve 3 and a discharge valve 10 for controlling their opening and closing. The metering bin 2 is provided with a plurality of transversely arranged blocking plates 4 along its length, which are used to partition the metering bin 2. Adjacent blocking plates 4 are spaced uniformly apart. Each blocking plate 4 has a feed hole 4a, and can move horizontally relative to the metering bin 2. During use, the feed port 2a of the metering bin 2 is connected to a storage bin, which stores toner, masterbatch, or plastic granules.

[0024] Specifically, the base 1 is also equipped with a cylinder 7 and a vertically positioned control panel 6 located on one side of the metering bin 2. The control panel 6 is detachably connected to a blocking plate 4. The control panel 6 has a plurality of fixing holes 6a formed along its length and is connected to the blocking plate 4 via bolts 9 passing through the fixing holes 6a. The output shaft of the cylinder 7 is arranged horizontally and connected to the control panel 6. The feed valve 3 and the discharge valve 10 are both plate-shaped, each having a feed hole positioned vertically opposite the feed port 2a and a discharge hole positioned vertically opposite the discharge port 2b, respectively. The discharge valve 10 is integrally formed on the control panel 6.

[0025] In this embodiment, it is preferred that the inner diameters of the feed hole 4a and the quantitative bin 2 are consistent.

[0026] Furthermore, one end of the blocking plate 4 is provided with an air blowing channel 8 along its length, with the air outlet of the air blowing channel 8 located vertically on the underside of the blocking plate 4. The blocking plate 4 also has an air inlet nozzle 4b connected to the air blowing channel 8. Considering the light weight of toner, the air inlet nozzle 4b of the air blowing channel 8 can be connected to an air source to promote the falling of the toner, thereby improving the quantitative delivery accuracy of the quantitative delivery device. Of course, the color masterbatch and plastic granules can also be selected according to actual needs.

[0027] When in use, the feed port 2a of the quantitative bin 2 is opened while the discharge port 2b is closed. At the same time, the feed hole 4a on the blocking plate 4 is arranged relative to the feed port 2a up and down. The color powder, masterbatch or plastic particles in the storage bin fill the space between the feed port 2a and the discharge port 2b of the quantitative bin 2. In addition, the spacing between adjacent blocking plates 4 on the quantitative bin of the quantitative conveying device is consistent, so that the volume of the quantitative bin 2 between adjacent blocking plates 4 is also determined and consistent. The user only needs to find the corresponding target according to the actual amount of color powder, masterbatch or plastic particles required. The blocking plate 4, specifically, if the volume between the blocking plate 4 and the discharge valve 10 is equal to the actual required amount of color powder, masterbatch or plastic particles, then the blocking plate 4 is the target blocking plate 4, and then the blocking plate 4 is connected to the control board 6 by the bolt 9 passing through the fixing hole 6a, and then the cylinder 7 is started to drive the blocking plate 4 to move until the feed hole 4a and the feed port 2a are offset up and down. At the same time, the cylinder 7 just drives the discharge valve 10 integrally formed with the control board 6 to open and output the material amount between the blocking plate 4 and the discharge valve 10.

[0028] In addition, during the movement of the blocking plate 4, the gas in the blowing channel 8 can promote the falling of the color powder, masterbatch or plastic particles, so that the color powder, masterbatch or plastic particles can fill the space between the blocking plate 4 and the discharge valve 10, thereby improving the quantitative delivery accuracy of the quantitative delivery device.

[0029] It should be noted that if the amount of toner, masterbatch or plastic granules obtained in one operation is not enough, the above steps can be repeated multiple times.

[0030] Example 2

[0031] The structure and principle of this embodiment are basically the same as those of the first embodiment, except that Figure 3-4A quantitative conveying device includes a machine base 1, on which a cylindrical quantitative bin 2 is provided. The quantitative bin 2 is vertically arranged, and the feed port 2a and the discharge port 2b of the quantitative bin 2 are respectively provided with a feed valve 3 and a discharge valve for controlling their opening and closing. The quantitative bin 2 is provided with a plurality of transversely arranged insertion holes 2c along its length direction, and the quantitative bin 2 can also be provided with a plurality of baffle rings 5 ​​for horizontal rotation. The spacing between adjacent baffle rings 5 ​​is consistent, one of the baffle rings 5 ​​is located outside the insertion hole 2c and a blocking plate 4 for isolating the quantitative bin 2 is provided in the insertion hole 2c, the blocking plate 4 has a feed hole 4a and can move horizontally relative to the quantitative bin 2, and the remaining baffle rings 5 ​​are located in the insertion hole 2c.

[0032] In this embodiment, the inner hole of the shielding ring 5 is preferably arranged relative to the feed port 2a, and the inner diameters of the shielding ring 5 and the quantitative bin 2 are consistent; preferably, a rotating shaft is vertically arranged on the quantitative bin 2, and the shielding ring 5 is sleeved on the rotating shaft.

[0033] When in use, the feed port 2a of the quantitative bin 2 is opened and the discharge port 2b is closed. At the same time, the feed hole 4a on the blocking plate 4 is arranged relative to the feed port 2a up and down. The color powder, masterbatch or plastic granules in the storage bin fills the space between the feed port 2a and the discharge port 2b of the quantitative bin 2. In addition, the spacing between adjacent blocking rings 5 ​​on the quantitative bin of the quantitative conveying device is consistent, so that the volume between adjacent blocking rings 5 ​​is also determined and consistent. The user only needs to find the corresponding target blocking ring 5 according to the actual amount of color powder, masterbatch or plastic granules required. Specifically, if the blocking ring 5 and the discharge valve 10 is equal to the actual required amount of color powder, masterbatch or plastic particles, then the blocking ring 5 is the target blocking ring 5, and then the user rotates the target blocking ring 5 out of the socket 2c, and then the user inserts the blocking plate 4 into the socket 2c, and connects the blocking plate 4 to the control board 6 through the bolt 9 passing through the fixing hole 6a, and then starts the cylinder 7 to drive the blocking plate 4 to move until the feed hole 4a and the feed port 2a are offset up and down. At the same time, the cylinder 7 just drives the discharge valve 10 integrally formed with the control board 6 to open and output the material amount between the blocking plate 4 and the discharge valve 10.

[0034] In addition, during the movement of the blocking plate 4, the gas in the blowing channel 8 can promote the falling of the color powder, masterbatch or plastic particles, so that the color powder, masterbatch or plastic particles can fill the space between the blocking plate 4 and the discharge valve 10, thereby improving the quantitative delivery accuracy of the quantitative delivery device.

[0035] It should be noted that if the amount of toner, masterbatch or plastic granules obtained in one operation is not enough, the above steps can be repeated multiple times.
