[0037] In this embodiment: the device for cleaning the outer bag and recovering dust before breaking the bag for feeding is mainly divided into three parts: an oscillating mechanism 1, a flattening mechanism 2 and a dust collecting mechanism 3. When the device is in use, first place the raw material packaging bag to be fed into the vibrating bucket 116. Then start the oscillating motor 109. Under the linkage of the active arm 110 and the driven arm 111 and the limiting effect of the oscillating frame 102, the vibrating bucket 116 will oscillate back and forth with a small amplitude. At this time, the debris on the surface of the packaging bag will fall into the recovery bin 124 below. When unloading is required, start the double-axis cylinder 108 and the flip cylinder 114 and drive the vibrating bucket 116 to flip to both sides. When the vibration tipping bucket 116 needs to flip to the left to discharge materials, the double-axis cylinder 108 is started to make the limit slider 121 on the left slide inward and limit the flip shaft 117 on the left, then the limit slider 121 on the right slides outward and disengages from the flip shaft 117 on the right, and finally the flip cylinder 114 is started to make the tooth plate 119 slide to the right. At this time, under the drive of the tooth plate 119, the vibration tipping bucket 116 flips with the gear 118 on the left and the flip shaft 117 on the left as the axis. When the vibration tipping bucket 116 needs to flip to the right to discharge materials, the double-axis cylinder 108 is started to make the limit slider 121 on the right slide outward and disengage from the flip shaft 117 on the right, then the limit slider 121 on the left slides inward and limits the flip shaft 117 on the left, and finally the flip cylinder 114 is started to make the tooth plate 119 slide to the left. At this time, driven by the tooth plate 119, the vibration bucket 116 turns over with the right gear 118 and the right turning shaft 117 as the axis. After the shaking, the packaging bag is transported to the bottom of the squeezing plate 206. With the cooperation of the linkage rod 214 and the adjustment frame 204, the squeezing plate 206 reciprocates up and down along the mounting frame 202 and flattens the packaging bag to prevent the unevenness from being inconvenient to enter the dust collection mechanism 3. After the packaging bag moves to the dust collection mechanism 3, when the dust collection roller 306 rotates, the dust remaining on the surface of the packaging bag will be sucked by the dust collection shaft 310 and transported to the recovery bin 124.

[0038] See attached Figure 2 -Attached Figure 3 A lower convex plate 103 is provided on the side wall of the base frame 101, an upper convex plate 104 is provided on the side wall of the oscillation frame 102, and an elastic element 105 is connected between the lower convex plate 103 and the upper convex plate 104; an oscillation motor 109 is also installed on the base frame 101, and an active arm 110 is connected to the output end of the oscillation motor 109, and a driven arm 111 is connected to the side wall of the oscillation frame 102, and the end of the active arm 110 is connected to the oscillation frame 102 through the driven arm 111.

[0039] In this embodiment, in order to automatically drive the vibration frame 102 and the vibration bucket 116 to vibrate, a structure of an elastic element 105 and a vibration motor 109 that cooperate with each other is designed.

[0040] See attached Figure 2 -Attached Figure 4 A through-limiting cavity 107 is provided on the flip seat 106, 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 double-axis cylinder 108 is installed in the middle of the oscillation frame 102, and the output ends of the double-axis cylinder 108 are fixedly connected to the connecting plates 122 on both sides.

[0041] In this embodiment, since the turning shaft 117 is movably arranged on the turning seat 106, when the vibrating bucket 116 and the vibration frame 102 unload materials to the left, the turning shaft 117 on the left needs to be limited. And when the vibrating bucket 116 and the vibration frame 102 unload materials to the right, the turning shaft 117 on the right needs to be limited, so a double-axis cylinder 108 structure is designed, and the turning shaft 117 is limited by a limiting slider 121.

[0042] See attached Figure 2 -Attached Figure 3 A through cavity 113 is opened in the middle of the slide groove 112, and a flip cylinder 114 is also installed at the bottom of the vibration frame 102. The output end of the flip cylinder 114 passes through the through cavity 113 and is fixedly connected to the tooth plate 119.

[0043] In this embodiment, in order to drive the tooth plate 119 to slide along the slide groove 112, so as to realize the vibration tipping bucket 116 and the vibration frame 102 to flip in different directions, a flip cylinder 114 structure is designed.

[0044] See attached Figure 2 -Attached Figure 3 A guide cover 123 located above the double-axis cylinder 108 is also installed in the middle of the oscillation frame 102, and a recovery bin 124 is also provided at the bottom of the base frame 101.

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

[0046] See attached Figure 5 -Attached Figure 7 Symmetrical lifting grooves 205 are provided on the inner walls on both sides of the mounting frame 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 thereto, and a rotating handle 209 is also provided on the outer side of the threaded rod 208.

[0047] In this embodiment: Since the specifications of the packaging bags containing different raw materials are different, in order to adjust the up and down movement amplitude of the extrusion plate 206, an adjustment frame 204 structure is designed. In order to facilitate the rotation of the threaded rod 208, thereby adjusting the position of the adjustment block 210, a rotating handle 209 structure is designed. When the adjustment block 210 is located at both ends of the adjustment frame 204 and away from the middle, the movement amplitude of the extrusion plate 206 becomes larger, and the lowest point is closer to the conveying mechanism 201, which is suitable for packaging bags with smaller thickness. When the adjustment block 210 is close to the middle, the movement amplitude of the extrusion plate 206 becomes smaller, and the lowest point is farther from the conveying mechanism 201, which is suitable for packaging bags with larger thickness.

[0048] See attached Figure 6 -Attached Figure 7 An upper mounting seat 211 is provided at the bottom of the adjusting block 210, a universal seat 212 is provided at the top of the extrusion plate 206, and a lower mounting seat 213 is provided at the top of the universal seat 212; an upper linkage seat 215 cooperating with the upper mounting seat 211 is provided at the top of the linkage rod 214, and a lower linkage seat 216 cooperating with the lower mounting seat 213 is provided at the bottom of the linkage rod 214.

[0049] In this embodiment, since the flattening motor 203 is not arranged in the middle of the mounting frame 202, the flattening motor 203 and the universal seat 212 are not arranged coaxially. Therefore, when the flattening motor 203 drives the adjustment frame 204 to rotate, the squeezing plate 206 will reciprocate up and down along the mounting frame 202, thereby flattening the packaging bag for subsequent cleaning operations.

[0050] See attached Figure 8 -Attached Fig.10 A plurality of lifting seats 303 are arranged on the fixed dust collecting frame 301, a plurality of lifting plates 304 movablely arranged in the lifting seats 303 are arranged at the bottom of the movable dust collecting frame 302, a plurality of return springs 305 are arranged inside the lifting seats 303, and the top of the return spring 305 is connected to the lifting plate 304.

[0051] In this embodiment: since the specifications of packaging bags containing different raw materials vary greatly and their heights after being flattened are also different, in order to improve the freedom and applicability of the equipment, the movable dust collection frame 302 is movably arranged on the top of the fixed dust collection frame 301.

[0052] See attached Figure 8 -Attached Fig.10A rotating shaft 308 is fixedly provided on the outer side of the dust suction roller 306, and the rotating shafts 308 on the fixed dust suction frame 301 and the movable dust suction frame 302 are connected to each other through a belt 309; the dust suction shaft 310 passes through the dust suction roller 306, and a joint 311 is movably provided on the outer side of the dust suction roller 306, the joints 311 on the fixed dust suction frame 301 are connected to each other through a hose 312, and the joint 311 on the movable dust suction frame 302 is connected to the hose 312 below through a connecting pipe 313, the hoses 312 are connected to each other and connected to the recovery bin 124, and a dust suction pump 314 is also installed at the end of the hose 312.

[0053] In this embodiment, in order to drive the upper and lower dust suction rollers 306 to rotate, so as to transport the packaging bag while performing the suction operation, the rotating shafts 308 on the fixed dust suction frame 301 and the movable dust suction frame 302 are connected to each other through a belt 309. When the dust suction rollers 306 rotate, the internal dust suction shafts 310 also rotate accordingly, so as to transport the dust remaining on the upper and lower sides of the packaging bag to the recovery bin 124.

[0054] See attached Fig.11 A convex ring 315 is provided at the end of the dust suction shaft 310 , and a rotation groove 316 cooperating with the convex ring 315 is opened on the inner wall of the joint 311 .

[0055] In this embodiment, in order to ensure that the dust suction shaft 310 can rotate freely relative to the joint 311 and prevent the connecting pipe 313 and the hose 312 from twisting and tangling, thereby affecting the subsequent dust suction operation, a convex ring 315 and a rotating groove 316 structure that cooperate with each other are designed.

[0056] Working principle of the present invention: When the device is in use, first place the raw material packaging bag to be fed into the vibration bucket 116. Then start the vibration motor 109, and under the linkage of the active arm 110 and the driven arm 111 and the limiting effect on the vibration frame 102, the vibration bucket 116 will reciprocate with a small amplitude, and the debris on the surface of the packaging bag will fall into the recovery bin 124 below. When it is necessary to unload materials, start the double-axis cylinder 108 and the flip cylinder 114 and drive the vibration bucket 116 to flip to both sides. When the vibration bucket 116 needs to flip to the left to unload materials, start the double-axis cylinder 108 to make the limit slider 121 on the left slide inward and limit the flip shaft 117 on the left, then make the limit slider 121 on the right slide outward and disengage from the flip shaft 117 on the right, and finally start the flip cylinder 114 to make the tooth plate 119 slide to the right. At this time, driven by the tooth plate 119, the vibration bucket 116 is turned over with the gear 118 on the left and the flip shaft 117 on the left as the axis. When the vibration bucket 116 needs to turn over to the right to discharge, the double-axis cylinder 108 is started to make the right limit slider 121 slide outward and disengage from the right flip shaft 117, then the left limit slider 121 slides inward and limits the left flip shaft 117, and finally the flip cylinder 114 is started to make the tooth plate 119 slide to the left. At this time, driven by the tooth plate 119, the vibration bucket 116 is turned over with the gear 118 on the right and the flip shaft 117 on the right as the axis. After the vibration is completed, the packaging bag is transported to the bottom of the extrusion plate 206. With the cooperation of the linkage rod 214 and the adjustment frame 204, the extrusion plate 206 reciprocates up and down along the mounting frame 202 and flattens the packaging bag to avoid unevenness and inconvenience in entering the dust collection mechanism 3. When the packaging bag moves to the dust collection mechanism 3 and the dust collection roller 306 rotates, the dust remaining on the surface of the packaging bag will be adsorbed by the dust collection shaft 310 and transported to the recovery bin 124 .
