[0002] After production, powdered or granular chemicals are typically bagged for easy storage and transportation. However, during the bagging process, especially as the material falls into the bag, dust is often released. To avoid impacting the surrounding working environment, a dust hood is usually added to the top of the bagging machine to stabilize the workshop environment. However, adding a dust hood is problematic because it cannot immediately remove the overflowing dust. Furthermore, most of the overflowing dust can be recycled, and directly sucking it out with a dust hood is inconvenient for collecting individual batches of material. Additionally, the material sucked into the dust collector is difficult to clean and remove, leading to inconvenient material recovery and potential waste. Utility Model Content

[0017] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] Please refer to the following: Figures 1 to 4 The dust removal device for bagging equipment provided by this utility model will now be described. The dust removal device for bagging equipment includes a mounting frame 1, a dust collection chamber 2, and a receiving box 3. A filling pipe for filling materials is installed on the mounting frame 1 in a vertical direction; the dust collection chamber 2 is installed on the mounting frame 1 and is located on one side of the bottom end of the filling pipe. An air inlet is provided on the side of the dust collection chamber 2 near the filling pipe, and an exhaust pipe 21 for connecting to a dust collector is also provided on the dust collection chamber 2; the receiving box 3 is detachably installed inside the dust collection chamber 2, and when the receiving box 3 is installed inside the dust collection chamber 2, both the air inlet and the exhaust pipe 21 are located above the receiving box 3.

[0019] The dust removal device for bagging equipment provided in this embodiment, compared with the prior art, features a mounting frame 1 fixedly installed on the ground. The filling tube of the filling equipment is fixedly installed on the mounting frame 1. During the filling process, the packaging bag is fitted onto the bottom of the filling tube, and the material is conveyed into the filling tube to perform the filling operation. This application includes a dust collection chamber 2 located on one side of the bottom of the filling tube. The air inlet of the dust collection chamber 2 is located near the bottom of the filling tube, and an exhaust pipe 21 is installed on the side of the dust collection chamber 2 away from the air inlet. The exhaust pipe 21 is used to connect to a dust collector. A material collection box 3 can also be detachably installed inside the dust collection chamber 2 for collecting materials. The material collection box 3 is installed at the bottom of the dust collection chamber 2. During operation, the dust collection chamber 2 can draw dust generated during the filling and bagging process into the dust collection chamber 2. Some of the dust is drawn into the dust collector through the exhaust pipe 21 and recovered through the filter bag inside the dust collector. Some of the dust will fall into the receiving box 3 due to its own gravity. After the same material is bagged, the receiving box 3 can be removed from the dust collection chamber 2, and the material inside the receiving box 3 can be recycled and reused, reducing material waste.

[0020] Specifically, in this embodiment, during actual application, some materials are recycled through the collection box 3, while the remaining materials are recycled through a vacuum cleaner. The collection box 3 is easier to disassemble and unload than the vacuum cleaner. Therefore, this application facilitates the collection and recycling of materials by designing the collection box 3 inside the vacuum chamber 2.

[0021] In some embodiments, the above-mentioned dust collection chamber 2 can be adopted as follows: Figure 1 , Figure 2 The structure shown. See also... Figure 1 , Figure 2 A grille plate 4 is fixedly installed on the outer wall of the dust collection chamber 2, covering the air inlet. The grille plate 4 has multiple ventilation holes. The grille plate 4 is bolted to the outer wall of the dust collection chamber 2, and is sealed to it. The grille plate 4 has multiple elongated oval ventilation holes. This design of the grille plate 4 reduces the cross-sectional area of ​​the air inlet, increasing the suction power during the suction process. It also prevents external debris from being sucked into the dust collection chamber 2.

[0022] Preferably, in this embodiment, the cross-sectional area inside the dust collection chamber 2 is larger than the total cross-sectional area of ​​the exhaust pipe 21 and the multiple ventilation holes on the grille plate 4. Therefore, when dust enters the dust collection chamber 2, the pressure inside the chamber moving with the wind decreases, and the dust easily falls into the collection box 3 under its own gravity, thus facilitating material collection.

[0023] In some embodiments, the receiving box 3 described above can be adopted as follows: Figure 1 , Figure 2The structure shown. See also... Figure 1 , Figure 2 The receiving box 3 is inserted into one side of the vacuum chamber 2, and a fixing plate 31 for fixing to the outer wall of the vacuum chamber 2 is fixedly installed at the end of the receiving box 3. An opening structure is provided on one side of the vacuum chamber 2, and the opening structure is located on the side wall adjacent to the air inlet and the exhaust pipe 21. The fixing plate 31 is fixedly installed at the end of the receiving box 3, and the four sides of the fixing plate 31 extend out of the receiving box 3. Rivet nuts are fixedly installed on the outer wall of the vacuum chamber 2, and the fixing plate 31 can be fixed to the side wall of the vacuum chamber 2 with bolts. When it is necessary to remove the receiving box 3, the receiving box 3 can be removed from the vacuum chamber 2 by removing the fixing plate 31. The structure is simple and the operation is convenient.

[0024] In some embodiments, the above-mentioned dust collection chamber 2 can be adopted as follows: Figure 2 , Figure 4 The structure shown. See also... Figure 2 , Figure 4 Two support rods 22 are fixedly installed at the bottom of the dust collection chamber 2 to support the two sides of the receiving box 3. The receiving box 3 is slidably mounted on the support rods 22. The length of the support rods 22 is aligned with the sliding direction of the receiving box 3. The top surfaces of the two support rods 22 protrude to provide an opening for mounting the receiving box 3. When the receiving box 3 is installed inside the dust collection chamber 2, its bottom slides on the support rods 22, thereby reducing the contact area between the receiving box 3 and the floor of the dust collection chamber 2, making it easier for operators to pull and slide the receiving box 3 inside the dust collection chamber 2.

[0025] Specifically, in this embodiment, the support rod 22 is made of square tubing. The two ends of the support rod 22 are welded and fixed to the side wall of the dust collection chamber 2, while the middle part of the support rod 22 is bolted and fixed to the side wall of the dust collection chamber 2. Reducing the welding area can reduce the deformation of the support rod 22 and the dust collection chamber 2.

[0026] In some embodiments, the above-mentioned dust collection chamber 2 can be adopted as follows: Figure 2 The structure shown. See also Figure 2A guide plate 23 is bent and installed on the inner wall of the dust collection chamber 2. The guide plate 23 is inclined from top to bottom into the dust collection chamber 2. After the receiving box 3 slides into the dust collection chamber 2, the top edges of the two opposite side walls of the receiving box 3 are located between the guide plate 23 and the inner wall of the dust collection chamber 2. The length direction of the guide plate 23 is along the sliding direction of the receiving box 3 inside the dust collection chamber 2. During the installation of the receiving box 3 into the dust collection chamber 2, the side walls of the receiving box 3 are located between the guide plate 23 and the inner wall of the dust collection chamber 2, and the guide plate 23 extends from top to bottom into the receiving box 3. The design of the guide plate 23 can reduce the amount of material falling into the gap between the receiving box 3 and the inner wall of the dust collection chamber 2. At the same time, it can guide the material falling onto the top surface of the guide plate 23 into the receiving box 3, reducing material waste.

[0027] Specifically, in this embodiment, the guide plate 23 near the air inlet of the dust collection chamber 2 is integrally bent and formed with the bottom side of the air inlet of the dust collection chamber 2. The guide plate 23 on the opposite side is fixedly installed on the side wall of the dust collection chamber 2 by bolts. A clearance is provided at the end of the receiving box 3 away from the fixing plate 31 to allow the guide plates 23 on both sides to pass.

[0028] In some embodiments, the above-mentioned dust collection chamber 2 can be adopted as follows: Figure 2 , Figure 3 The structure shown. See also... Figure 2 , Figure 3 The dust collection chamber 2 has an opening on one side for installing the receiving box 3, and a sealing strip 5 is fixedly installed on the inner wall of the dust collection chamber 2 away from the opening. After the receiving box 3 is installed inside the dust collection chamber 2, the end of the receiving box 3 abuts against the sealing strip 5. The dust collection chamber 2 has two opposite side walls with openings for installing the receiving box 3 and sealing strips 5 respectively. The length of the sealing strip 5 is along the width of the receiving box 3. When the receiving box 3 is fixed to the dust collection chamber 2, the end of the receiving box 3 away from the fixing plate 31 abuts against the sealing strip 5, achieving a seal between the outer end face of the receiving box 3 and the dust collection chamber 2.

[0029] Preferably, in this embodiment, the fixing plate 31 on the receiving box 3 is fixedly installed on the outer wall of the dust collection chamber 2 by bolts. The design of the sealing strip 5 increases the friction between the receiving box 3 and the inner wall of the dust collection chamber 2, improving the stability of the receiving box 3 in its fixed position inside the dust collection chamber 2. This reduces vibration of the receiving box 3 inside the dust collection chamber 2 and lowers noise levels.

[0030] In some embodiments, the receiving box 3 described above can be adopted as follows: Figure 3 The structure shown. See also Figure 3The receiving box 3 has a sealing plate 32 bent outward at its end for abutting against the sealing strip 5. The sealing plate 32 is parallel to the end face of the receiving box 3. The sealing plate 32 is located on the side wall of the receiving box 3 away from the fixing plate 31 and is integrally bent into shape with the side wall. The sealing plate 32 is bent outward and adheres to the outer side wall of the receiving box 3. When the receiving box 3 is pushed into the dust collection chamber 2, the sealing plate 32 at the end of the receiving box 3 abuts against the sealing strip 5. This improves the stability of the fit between the receiving box 3 and the sealing strip 5. At the same time, the integral bending of the sealing plate 32 with the top side of the side wall of the receiving box 3 prevents damage to the sealing strip 5 and extends the service life of the sealing strip 5.

[0031] In some embodiments, the above-mentioned dust collection chamber 2 can be adopted as follows: Figure 1 The structure shown. See also Figure 1 A sealing strip 6 is fixedly installed around the opening of the dust collection chamber 2. When the fixing plate 31 is fixed to the outer wall of the dust collection chamber 2, it is sealed to the dust collection chamber 2 through the sealing strip 6. The sealing strip 6 is also glued and fixedly installed on the side wall of the dust collection chamber 2 with the opening, and the sealing strip 6 is glued around the opening. When the fixing plate 31 is fixed to the outer wall of the dust collection chamber 2, the sealing strip 6 achieves a sealed connection between the fixing plate 31 and the outer wall of the dust collection chamber 2. This improves the sealing performance of the dust collection chamber 2 and ensures effective dust collection.

[0032] In some embodiments, the above-mentioned dust collection chamber 2 can be adopted as follows: Figure 4 The structure shown. See also Figure 4 The dust collection chamber 2 includes a lower sealing plate 24 fixedly installed at the bottom of a support rod 22, and a fastener 241 for fixing the lower sealing plate 24 to the support rod 22 is threadedly connected to the support rod 22. The dust collection chamber 2 includes an upper sealing plate and a lower sealing plate 24 spaced apart in a vertical direction, both of which are sealed to the inner wall of the dust collection chamber 2. A receiving box 3 is located between the upper sealing plate and the lower sealing plate 24. The upper sealing plate has mounting plates bent around its perimeter for fixing to the inner wall of the dust collection chamber 2. The support rod 22 is fixedly installed on the side wall of the dust collection chamber 2 by bolts, and the lower sealing plate 24 is fixedly installed at the bottom of the support rod 22. The fastener 241 is a bolt, and a rivet nut is fixedly installed on the support rod 22. The lower sealing plate 24 can be fixedly installed to the support rod 22 by the fastener 241. Compared with welding, this method can reduce the deformation of the support rod 22 and ensure the stability of the receiving box 3 after it is installed inside the dust collection chamber 2.

[0033] In some embodiments, the lower sealing plate 24 may be adopted as follows: Figure 4 The structure shown. See also Figure 4A sealant 242 is applied between the lower sealing plate 24 and the inner wall of the dust collection chamber 2. After the upper and lower sealing plates 24 are installed on the inner wall of the dust collection chamber 2, the sealant 242 is applied to the gaps between the upper and lower sealing plates 24 and the inner wall of the dust collection chamber 2 to improve the sealing effect between the upper and lower sealing plates 24 and the dust collection chamber 2. This allows air to circulate between the air inlet and the exhaust pipe 21 of the dust collection chamber 2.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
