DETAILED DESCRIPTION

[0036] The application will be further described below in connection with the embodiments and the accompanying drawings.

[0037] Example one: as Figure 1 , 7The dustproof bagging system for the glaze ball milling processing terminal comprises a discharge pipe 4, a negative pressure dust collection pipe 5, a support 1, a bagging and dust removal device 2 mounted on the support 1, and a bag receiving and conveying frame 3. The bagging and dust removal device 2 is located above the bag receiving and conveying frame 3. The bagging and dust removal device 2 comprises a deflectable packaging box 21 and a dust remover mounted on the packaging box 21. The upper end of the packaging box 21 is provided with an opening 1 2101. Below the opening 1 2101 is a negative pressure inner space 210 which is in communication with the negative pressure dust collection pipe 5. The dust remover comprises a rotating cage 22 having an opening 2 2201 at the upper end and a driving motor 23 for driving the rotating cage 22 to rotate. The rotating cage 22 is located in the negative pressure inner space 210. A charging bag 6 can be placed into the rotating cage 22 with the bag opening upward. The discharge pipe 4 can extend downward through the opening 1 2101 of the packaging box 21 to above the opening 2 2201 of the rotating cage 22 to charge the charging bag 6 and withdraw upward from the opening 1 2101 after the charging is completed. After the bagging is completed, the rotating cage 22 can rotate in the negative pressure environment to remove dust from the charging bag 6. In application, the charging bag 6 is placed into the rotating cage 22 with the bag opening upward, so that the packaging box 21 is in a vertical state. The lower end of the discharge pipe 4 extends downward through the opening 1 2101 of the packaging box 21 to above the opening 2 2201 of the rotating cage 22. The bag opening of the charging bag 6 is sleeved on the discharge pipe 4. Under the condition that the negative pressure inner space 210 forms negative pressure when the negative pressure dust collection pipe 5 starts to work, the discharge pipe 4 transports glaze powder into the charging bag 6 for bagging. After the bagging is completed, the bag opening of the charging bag 6 is tightly tied with a soft rope 61. The discharge pipe 4 is retracted upward. The packaging box 21 is deflected by an angle of 90 degrees. The rotating cage 22 is deflected to make the rotating cage 22 in a lying state. The rotating cage 22 is driven to rotate by the driving motor 23. Since the rotating cage 22 is deflected, the charging bag 6 filled with glaze is continuously rolled and changed in direction in the rotating rotating cage 22 and bumps against the inner wall of the rotating cage 22, so that the dust on the body of the charging bag 6 is shaken off and is sucked away by the negative pressure airflow, thereby completing the dust removal on the surface of the charging bag 6. The deflection of the packaging box 21 is continued until the opening 2 2201 of the rotating cage 22 faces downward. The charging bag 6 after the dust removal is slid out of the rotating cage 22 to the bag receiving and conveying frame 3 under the action of gravity. The bag receiving and conveying frame 3 sends away the charging bag 6. In this way, the bagging and the dust removal are both carried out in the negative pressure environment of the negative pressure inner space 210. Not only the bagging process is free of dust drifting, but also the charging bag 6 filled with glaze powder will not drift dust in the transfer and stacking process, thereby ensuring that the air cleanliness in the processing workshop meets the standard and the health of workers is ensured.

[0038] One bag receiving and conveying frame 3 can correspond to multiple glaze ball milling processing devices. That is, multiple glaze ball milling processing devices are all arranged above the bag receiving and conveying frame 3 to receive the charging bags 6 dropped by the devices and send the charging bags 6 to designated positions.

[0039] The negative pressure dust collection pipe 5 is connected to a negative pressure dust collection system, which is a prior art. The basic structure of the negative pressure dust collection system includes a negative pressure pipeline, a dust collection chamber and an air extractor. The air extractor is arranged at the terminal of the negative pressure pipeline. The negative pressure pipeline passes through the dust collection chamber, and the dust in the airflow is collected by the dust collection chamber.

[0040] The discharge pipe 4 is located at the terminal of the glaze ball milling process, and the upstream of the discharge pipe 4 is a powder heat treatment section. The starting end of the glaze ball milling process is a ball mill, which is used to dry mill large raw materials into qualified fine powder.

[0041] As shown in Figure 8 , 9 , the loading bag 6 filled with glaze powder has a diameter smaller than the inner diameter of the space in the rotating cage 22.

[0042] As shown in Figure 1 , 2 , the rotating shaft one 211 and the rotating shaft two 212 with a common axis are arranged on the support 1 at the middle area of the two sides of the packaging box 21, so that the packaging box 21 and the dust remover can deflect around the axis.

[0043] The rotating shaft one 211 is a hollow shaft with a negative pressure air outlet hole 2110, which is rotatably arranged on the support 1. The inner end of the negative pressure air outlet hole 2110 is communicated with the negative pressure inner space 210, and the outer end is communicated with the pipe hole of the negative pressure dust collection pipe 5. The negative pressure dust collection pipe 5 is movably connected with the rotating shaft one 211 by sleeving the outer end of the rotating shaft one 211, so that the negative pressure dust collection pipe 5 can rotate relative to the rotating shaft one 211. A wear-resistant sealing ring 2112 is arranged between the inner wall of the negative pressure dust collection pipe 5 and the outer peripheral surface of the outer end of the rotating shaft one 211. In this way, when the rotating shaft one 211 deflects with the packaging box 21, the negative pressure dust collection pipe 5 can not rotate, and the rotating shaft one 211 with the negative pressure air outlet hole 2110 and the negative pressure dust collection pipe 5 are also air-tight. The rotating shaft one 211 not only plays a role of supporting the rotating shaft, but also plays a role of connecting the negative pressure inner space 210 and the negative pressure dust collection pipe 5.

[0044] The rotating shaft one 211 close to the outer wall of the packaging box 21 is fixedly provided with a deflection gear 2111. The packaging box 21 beside the deflection gear 2111 is provided with a servo motor 216. The servo motor 216 has a deflection driving gear 2161. The deflection driving gear 2161 is engaged with the deflection gear 2111. In use, the packaging box 21 is driven to deflect by the servo motor 216 at a set angle.

[0045] As shown in Figure 3 , 4As shown in Figure 6, two annular tracks 221 are provided on the outer periphery of the rotating cage 22. Each annular track 221 has multiple limiting wheels 213 corresponding to the inner wall of the packaging box 21. Each limiting wheel 213 is rotatably mounted on its respective support 214. The support 214 is fixed to the inner wall of the packaging box 21. The outer periphery of the limiting wheel 213 has a limiting groove 2131. The outer edge of the annular track 221 is located in the limiting groove 2131 of its respective limiting wheel 213. When the annular track 221 rotates with the rotating cage 22, the limiting wheel 213 can rotate around its own axis. In this way, the rotating cage 22 is confined in the negative pressure space 210 of the packaging box 21 by the annular track 221 and the limiting wheel 213, and can rotate around its own axis in the negative pressure space 210.

[0046] like Figure 6 As shown, the bottom of the packaging box 21 is provided with a bottom wall 217, and a shaft hole is provided in the center of the bottom wall 217. The bottom of the rotating cage 22 is provided with a driven shaft 222 located inside the packaging box 21. A driven gear 223 is provided on the driven shaft 222. The drive motor 23 is located outside the bottom wall 217, and its drive shaft 231 extends into the packaging box 21 through the shaft hole. A drive gear 232 is provided on the drive shaft 231 located inside the packaging box 21. The drive gear 232 meshes with the driven gear 223. The drive motor 23 drives the rotating cage 22 to rotate through this transmission relationship.

[0047] like Figure 1 , 2 As shown in Figures 9 and 10, the bag receiving and conveying frame 3 comprises two side beams 31, rollers 32 equally spaced between the two side beams 31, a transmission belt 33 connecting adjacent rollers 32, and a transmission motor 34 providing transmission power. The length of the bag receiving and conveying frame 3 can be set as needed, and multiple transmission motors 34 can be spaced out on one bag receiving and conveying frame 3.

[0048] like Figure 1 , 2 As shown in Figures 7, 8, 9, and 11, an extension sleeve 41 is provided on the outer periphery of the lower end of the discharge pipe 4. The extension sleeve 41 can slide up and down on the outer periphery of the lower end of the discharge pipe 4. The discharge pipe 4 can extend downward through the opening 2101 of the packaging box 21 to above the opening 2201 of the rotating drum 22. This means that the extension sleeve 41 can extend downward through the opening 2101 of the packaging box 21 to above the opening 2201 of the rotating drum 22. After bagging is completed, the extension sleeve 41 can be lifted up to above the opening 2101 of the packaging box 21 so that it does not interfere with the deflection of the packaging box 21.

[0049] In this embodiment, during bagging, the worker reaches through the opening 2101 of the sealing box 21 and enters above the opening 2201 of the rotating drum 22 to perform the operation.

[0050] In this embodiment, although the opening 2101 of the packaging box 21 is in an open state, as long as the suction volume of the negative pressure suction pipe 5 is large enough, when the bagging or dust removal function is performed in the negative pressure inner space 210 below the opening 2101 of the packaging box 21, there will be basically no glaze powder drifting outward.

[0051] Example 2. (As shown in the original text) Figures 12-17 As shown, the difference between this and Embodiment 1 is that the bagging and dust removal device 2 further includes a dust cover 24 for shielding the opening 2101 of the packaging box 21; the dust cover 24 is an arc-shaped plate fixedly installed on the same axis as the rotating shaft 211 or the rotating shaft 212, with its upper end located in the 10 o'clock area and its lower end located in the 4 o'clock area; the edge of the opening 2101 of the packaging box 21 is always close to the inner side of the dust cover 24 within the coverage area of ​​the dust cover 24, the dust cover 24 is provided with an inlet hole 241 for the discharge pipe 4 to extend into in the 12 o'clock area, and the upper part of the packaging box 21 wall located on the side of the rotating shaft 212 is provided with operation holes 215 for the left and right hands to extend into the negative pressure inner space 210 respectively; there is an air inlet gap 25 between the opening 2101 of the packaging box 21 and the dust cover 24. The application sequence is as follows: Rotate the packaging box 21 to the left, so that the opening 2201 of the rotating cage 22 is exposed from the top of the dust cover 24 at the nine o'clock position, for placing the filling bag 6 into the rotating cage 22; rotate the packaging box 21 back so that the opening 2201 of the rotating cage 22 faces upwards at the twelve o'clock position, and pass the extension sleeve 41 downwards through the inlet hole 241 of the dust cover 24 to the top of the opening 2201 of the rotating cage 22, filling the bag as described in Embodiment 1 and tying the bag opening tightly; rotate the packaging box 21 to the right to a horizontal position, and rotate the rotating cage 22 to remove dust as described in Embodiment 1; rotate the packaging box 21 to the right so that the opening 2201 of the rotating cage 22 is exposed at the bottom of the dust cover 24 below the four o'clock position, and the filling bag 6 filled with glaze slides out to the bag receiving and transfer rack 3 as described in Embodiment 1. In this way, the dust cover 24 can seal the opening 2101 of the packaging box 21 over a large area, preventing dust from spreading during operation.

[0052] Here, the clock reading positioning is based on the orientation when the clock reading is directly above twelve o'clock.

[0053] Because the dust cover 24 blocks the opening 2101 of the packaging box 21, the worker can insert his left and right hands into the negative pressure space 210 through the operating hole 215 to perform the bagging operation.

[0054] like Figure 15 , 17 As shown, since the dust during bagging and dust removal will be scattered in the negative pressure space 210, there needs to be an air inlet gap 25 between the opening 2101 of the sealing box 21 and the dust cover 24 to allow gas to continuously enter, thereby sucking away the dust scattered in the negative pressure space 210 by the negative pressure suction pipe 5.

[0055] The dust cover 24 can be fixed on the support 1 (the support structure is not shown in the figure).

[0056] As shown in Figure 12 Further, a sleeve 2151 is arranged in the operation hole 215, which is made of elastic fabric, the outer end of which is fixed on the inner wall of the operation hole 215, and the inner end is elastically contracted into a hand hole 2150 which can be expanded. The purpose of this arrangement is also to moderately block the operation hole 215.

[0057] Further, the dust cover 24 is made of transparent organic material, which is convenient for workers to observe the bagging.

[0058] The above embodiments are only used for more clearly describing the present application, and cannot be considered as limiting the protection scope of the present application, and any equivalent modification shall be considered as falling into the protection scope of the present application.
