Polyethylene is odorless, non-toxic, and has a waxy feel. It possesses excellent low-temperature resistance, good chemical stability, and resistance to most acids and alkalis. It is insoluble in common solvents at room temperature, has low water absorption, and excellent electrical insulation properties. Therefore, polyethylene is commonly used in the production of woven bags. In blown film bag making, to control the introduction of foreign matter, the outer packaging bags of the raw materials need to be cleaned one by one during the feeding process to prevent foreign matter adhering to the outer packaging from entering the feeding hopper along with the raw materials during the shaking and breaking of the packaging.

[0017] 1. This invention utilizes a vibration mechanism to screen packaging bags filled with raw materials. With the cooperation of the active and driven arms, the vibration frame oscillates back and forth relative to the base frame. After vibration, when the vibrating bucket needs to be tilted to the left for unloading, the dual-axis cylinder is activated to slide the left-side limiting slider inwards and limit the left-side tilting shaft. Then, the right-side limiting slider slides outwards and disengages from the right-side tilting shaft. Finally, the tilting cylinder is activated to slide the toothed plate to the right. When the vibrating bucket needs to be tilted to the right for unloading, the dual-axis cylinder is activated to slide the right-side limiting slider outwards and disengage from the right-side tilting shaft.

This design improves the processing efficiency of the outer packaging bag cleaning and dust collection device. Attached Figure Description

A toothed plate 119 is slidably arranged in the sliding groove 112. A flipping shaft 117 is fixedly arranged at the bottom of the vibrating tipping bucket 116 and movably arranged in the flipping seat 106. A gear 118 is installed on the outer side of the flipping shaft 117. The two ends of the toothed plate 119 are provided with meshing teeth 120 that cooperate with the gear 118. The flattening mechanism 2... The system includes a conveying mechanism 201 symmetrically arranged on both sides of the base frame 101. A mounting frame 202 is provided in the middle of the conveying mechanism 201. A flattening motor 203, which is not located in the middle, is installed on the top of the mounting frame 202. An adjusting frame 204 is connected to the output end of the flattening motor 203. An extrusion plate 206 is slidably arranged on the inner wall of the mounting frame 202. An adjusting block 210 is threaded on the adjusting frame 204. The middle of the extrusion plate 206 is movably connected to the adjusting block 210 through a linkage rod 214. The vacuuming mechanism 3 includes a fixed vacuuming frame 301 located outside the conveying mechanism 201. A movable vacuuming frame 302 is movably arranged on the top of the fixed vacuuming frame 301. Multiple sets of vacuuming rollers 306 are movably arranged on both the fixed vacuuming frame 301 and the movable vacuuming frame 302. A vacuuming shaft 310 is fixedly arranged in the middle of the vacuuming roller 306. Multiple sets of slots 307 are opened on the vacuuming roller 306.

[0037] In this embodiment, the device for cleaning outer packaging bags and recovering dust before unpacking and feeding mainly consists of three parts: a vibration mechanism 1, a flattening mechanism 2, and a dust collection mechanism 3. When in use, the raw material packaging bag to be fed is first placed into the vibrating tipping bucket 116. Then, the vibration motor 109 is started. Under the linkage of the active arm 110 and the driven arm 111, and the limiting effect of the vibration frame 102, the vibrating tipping bucket 116 will vibrate back and forth with small amplitudes. At this time, the debris on the surface of the packaging bag will fall into the recovery bin 124 below. When feeding is required, the dual-shaft cylinder 108 and the tilting cylinder 114 are activated, driving the vibrating tipping bucket 116 to tilt to both sides. When the vibrating tipper 116 needs to tilt to the left to unload material, the dual-axis cylinder 108 is activated, causing the left limiting slider 121 to slide inward and limit the left tilting shaft 117. Then, the right limiting slider 121 slides outward and disengages from the right tilting shaft 117. Finally, the tilting cylinder 114 is activated, causing the toothed plate 119 to slide to the right. At this time, driven by the toothed plate 119, the vibrating tipper 116 tilts around the left gear 118 and the left tilting shaft 117. When the vibrating tipper 116 needs to tilt to the right to unload material, the dual-axis cylinder 108 is activated, causing the right limiting slider 121 to slide outward and disengage from the right tilting shaft 117. Then, the left limiting slider 121 slides inward and limits the left tilting shaft 117. Finally, the tilting cylinder 114 is activated, causing the toothed plate 119 to slide to the left. Driven by the toothed plate 119, the vibrating tipping bucket 116 rotates around the right gear 118 and the right tilting shaft 117. After vibration, the packaging bag is conveyed to the area below the extrusion plate 206. With the cooperation of the linkage rod 214 and the adjusting frame 204, the extrusion plate 206 moves up and down along the mounting frame 202 to flatten the packaging bag, preventing unevenness from hindering its entry into the dust collection mechanism 3. When the packaging bag reaches the dust collection mechanism 3, the dust collection roller 306 rotates, and the dust remaining on the surface of the packaging bag is absorbed by the dust collection shaft 310 and conveyed to the recycling bin 124.

[0038] See appendix Figure 2 -Appendix Figure 3 The base frame 101 has a lower convex plate 103 on its side wall, and the vibrating frame 102 has an upper convex plate 104 on its side wall. An elastic element 105 is connected between the lower convex plate 103 and the upper convex plate 104. The base frame 101 is also equipped with a vibrating motor 109. The output end of the vibrating motor 109 is connected to an active arm 110. The vibrating frame 102 has a driven arm 111 connected to its side wall. The end of the active arm 110 is connected to the vibrating frame 102 through the driven arm 111.

[0039] In this embodiment: In order to automatically drive the vibration frame 102 and the vibrating tipping bucket 116 to vibrate, a structure of mutually cooperating elastic element 105 and vibration motor 109 is designed.

[0040] See appendix Figure 2 - Appendix Figure 4 The flipping seat 106 has a through limiting cavity 107, and a limiting slider 121 is slidably arranged in the limiting cavity 107. The limiting sliders 121 located on the same side are connected by a connecting plate 122. A dual-axis cylinder 108 is installed in the middle of the vibration frame 102, and the output end of the dual-axis cylinder 108 is fixedly connected to the connecting plates 122 on both sides.

[0041] In this embodiment: Since the tilting shaft 117 is movably mounted on the tilting seat 106, when the vibrating bucket 116 and the vibrating frame 102 discharge material to the left, the tilting shaft 117 on the left needs to be limited. And when the vibrating bucket 116 and the vibrating frame 102 discharge material to the right, the tilting shaft 117 on the right needs to be limited. Therefore, a dual-axis cylinder 108 structure is designed, and the tilting shaft 117 is limited by the limiting slider 121.

[0042] See appendix Figure 2 - Appendix Figure 3 A through cavity 113 is provided in the middle of the slide 112, and a tilting cylinder 114 is also installed at the bottom of the vibration frame 102. The output end of the tilting cylinder 114 passes through the through cavity 113 and is fixedly connected to the toothed plate 119.

[0043] In this embodiment: In order to drive the toothed plate 119 to slide along the slide groove 112, thereby realizing the vibrating tipping bucket 116 and the vibrating frame 102 to flip in different directions, a flipping cylinder 114 structure is designed.

[0044] See appendix Figure 2 - Appendix Figure 3 The middle part of the vibration frame 102 is also equipped with a flow guide 123 located above the dual-shaft cylinder 108, and the bottom of the base frame 101 is also equipped with a recovery chamber 124.

[0045] In this embodiment: when dust falls, in order to prevent debris from falling onto the vibrating frame 102 and affecting the subsequent operation of the dual-axis cylinder 108, a guide shroud 123 structure is designed.

[0046] See appendix Figure 5 - Appendix Figure 7 Symmetrical lifting grooves 205 are provided on the inner walls of both sides of the mounting bracket 202, and sliding arms 207 are provided on both sides of the extrusion plate 206; a threaded rod 208 is movably provided in the middle of the adjustment frame 204, the threaded rod 208 passes through the adjustment block 210 and is threadedly connected to it, and a rotating handle 209 is also provided on the outer side of the threaded rod 208.

[0047] In this embodiment: Since the packaging bags containing different raw materials have different specifications, an adjusting frame 204 structure is designed to adjust the vertical movement range of the extrusion plate 206. A rotating handle 209 structure is designed to facilitate the rotation of the threaded rod 208 to adjust the position of the adjusting block 210. When the adjusting block 210 is located at both ends of the adjusting frame 204 and far from the center, the movement range of the extrusion plate 206 increases, and the lowest point is closer to the conveying mechanism 201, suitable for packaging bags with smaller thicknesses. When the adjusting block 210 is close to the center, the movement range of the extrusion plate 206 decreases, and the lowest point is farther from the conveying mechanism 201, suitable for packaging bags with larger thicknesses.

[0048] See appendix Figure 6 - Appendix Figure 7 The bottom of the adjusting block 210 is provided with an upper mounting seat 211, the top of the pressing plate 206 is provided with a universal seat 212, and the top of the universal seat 212 is provided with a lower mounting seat 213; the top of the linkage rod 214 is provided with an upper linkage seat 215 that cooperates with the upper mounting seat 211, and the bottom of the linkage rod 214 is provided with a lower linkage seat 216 that cooperates with the lower mounting seat 213.

[0049] In this embodiment: Since the flattening motor 203 is not located in the middle of the mounting frame 202, the flattening motor 203 and the universal joint 212 are not coaxially arranged. Therefore, when the flattening motor 203 drives the adjusting frame 204 to rotate, the extrusion plate 206 will move up and down along the mounting frame 202 to flatten the packaging bag for subsequent cleaning operations.

[0050] See appendix Figure 8 - Appendix Figure 10 The fixed vacuum cleaner frame 301 is provided with multiple lifting seats 303, and the bottom of the movable vacuum cleaner frame 302 is provided with multiple lifting plates 304 that are movably disposed in the lifting seats 303. The interior of the lifting seats 303 is provided with multiple return springs 305, and the top of the return springs 305 is connected to the lifting plates 304.

[0051] In this embodiment: Since the packaging bags containing different raw materials have different specifications and different heights after being flattened, in order to improve the freedom of movement and applicability of the equipment, the moving vacuum cleaner frame 302 is movably set on top of the fixed vacuum cleaner frame 301.

[0052] See appendix Figure 8 - Appendix Figure 10A rotating shaft 308 is fixedly installed on the outer side of the suction roller 306. The rotating shaft 308 located on the fixed suction frame 301 and the moving suction frame 302 are connected to each other by a belt 309. The suction shaft 310 passes through the suction roller 306. A connector 311 is movably installed on the outer side of the suction roller 306. The connector 311 located on the fixed suction frame 301 is connected to each other by a hose 312. The connector 311 located on the moving suction frame 302 is connected to the hose 312 below by a connecting pipe 313. The hoses 312 are connected to each other and connected to the recycling bin 124. A suction pump 314 is also installed at the end of the hose 312.

[0053] In this embodiment: to drive the upper and lower suction rollers 306 to rotate, thereby conveying the packaging bag while performing suction operations, the rotating shafts 308 located on the fixed suction frame 301 and the moving suction frame 302 are connected to each other by a belt 309. When the suction rollers 306 rotate, the internal suction shaft 310 also rotates, thereby conveying the dust remaining on the upper and lower sides of the packaging bag to the recycling bin 124.

[0054] See appendix Figure 11 The end of the suction shaft 310 is provided with a protruding ring 315, and the inner wall of the connector 311 is provided with a rotating groove 316 that cooperates with the protruding ring 315.

[0055] In this embodiment: In order to ensure that the suction shaft 310 can rotate freely relative to the connector 311 and to prevent the connecting tube 313 and the hose 312 from twisting and knotting, thus affecting the subsequent suction operation, a structure with a convex ring 315 and a rotating groove 316 that cooperate with each other is designed.

[0056] The working principle of this invention is as follows: When using the equipment, firstly, the raw material packaging bag to be fed is placed into the vibrating tipping bucket 116. Then, the vibrating motor 109 is started. Under the linkage of the driving arm 110 and the driven arm 111, and the limiting action of the vibrating frame 102, the vibrating tipping bucket 116 will reciprocate with small amplitude vibrations. At this time, the debris on the surface of the packaging bag will fall into the recycling bin 124 below. When material needs to be discharged, the dual-axis cylinder 108 and the tilting cylinder 114 are activated to drive the vibrating tipping bucket 116 to tilt to both sides. When the vibrating tipping bucket 116 needs to tilt to the left to discharge material, the dual-axis cylinder 108 is activated to make the left limiting slider 121 slide inward and limit the left tilting shaft 117. Then, the right limiting slider 121 slides outward and disengages from the right tilting shaft 117. Finally, the tilting cylinder 114 is activated to make the toothed plate 119 slide to the right. Driven by the toothed plate 119, the vibrating tipping bucket 116 rotates around the left gear 118 and the left tilting shaft 117. When the vibrating tipping bucket 116 needs to tilt to the right to unload material, the dual-axis cylinder 108 is activated to make the right limit slider 121 slide outward and disengage from the right tilting shaft 117. Then, the left limit slider 121 slides inward and limits the left tilting shaft 117. Finally, the tilting cylinder 114 is activated to make the toothed plate 119 slide to the left. Driven by the toothed plate 119, the vibrating tipping bucket 116 rotates around the right gear 118 and the right tilting shaft 117. After vibration, the packaging bag is conveyed to the bottom of the extrusion plate 206. With the cooperation of the linkage rod 214 and the adjusting frame 204, the extrusion plate 206 moves up and down along the mounting frame 202 and flattens the packaging bag, preventing unevenness from making it inconvenient to enter the vacuuming mechanism 3. When the packaging bag moves to the dust collection mechanism 3, the dust collection roller 306 rotates, and the dust remaining on the surface of the packaging bag is absorbed by the dust collection shaft 310 and transported to the recycling bin 124.
