[0016] Compared with the prior art, the advantages of this utility model are as follows: 1. When this utility model is used, the bag opening and fixing component will adsorb and fix the bag containing powder and open it. The clamping and sealing component will be driven to rotate and move down by the lifting and feeding component, extending the position of the feeding pipe opening, sealing the upper end of the bag and fixing it at the feeding port. The lifting and feeding component will also perform dust suction at the same time. The three sets of bag opening and fixing components realize multi-station bag support, which facilitates rapid filling. The external motor drives the turntable to rotate and change the position of the bag opening and fixing component for filling powder, realizing efficient bagging of powder coating and dust prevention.

[0017] 2. When using this utility model, if it is necessary to fix and open the bag, the output end of the cylinder drives the slide plate connected to the cylinder to move along the slide groove to the slide plate on the other side. After only a small gap is left between the two sets of slide plates, the bag is placed into the gap. The cylinder continues to drive so that the suction cups contact the side wall of the bag. The suction cups are treated by the external air extraction device. At this time, the suction cups adhere to both sides of the bag. The cylinder drives the gap between the slide plates to open the bag opening, realizing the automatic opening of the bag. The upper and lower sets of suction cups pull the bag open as a whole, realizing the effective opening of the feeding port.

[0018] 3. When using this utility model, if powder feeding is required, powder is added from the feeding port of the feeding hopper. The powder passes through the feeding port of the feeding hopper and the sleeve, and finally enters the bag from the feeding port of the sleeve. At the same time, a vacuum cleaner connected to the external suction pipe removes the dust generated near the bag opening during feeding. If clamping and sealing feeding is required, the output end of the motor drives the lead screw to rotate. The lead screw drives the clamping and sealing assembly to move. The front clamping and sealing assembly drives the collar to move down. The collar drives the sleeve to move down. The collar drives the rear clamping and sealing assembly to move down along the slide rod. At this time, the sleeve moves down into the open bag opening. The clamping and sealing assembly rotates to clamp the bag between the sleeve and the clamping and sealing assembly, and the bag opening only leaves a space communicating with the feeding port of the collar, so as to achieve a sealed and dustproof bag opening during bagging.

[0019] 4. When using this utility model, if it is necessary to clamp the bag, the motor drives the lead screw to rotate. The lead screw drives the front slider to move down along the U-shaped plate. The front slider drives the front connecting rod to move down and move closer together. The first connecting rod on the front side drives the clamping plate to move. The clamping plate drives the second and third connecting rods on the front side to rotate, so that the clamping plates move closer together and downward. The first connecting rod on the front side drives the second and third connecting rods on the front side and the clamping plate to move down and rotate. The front slider drives the collar to descend. The collar drives the rear slider to move down along the sliding rod. The rear slider drives the rear connecting rod to move down. They move closer together, and the first connecting rod on the rear side drives the clamping plate to move. The clamping plate drives the second and third connecting rods on the rear side to rotate. The clamping plate drives the first, second, and third connecting rods on the rear side to move downward and rotate. The first connecting rod on the rear side drives the slider on the rear side to move along the sliding rod, so that the clamping plate rotates and moves closer to the opposite direction. This achieves the clamping plate moving closer together and clamping during the downward movement, pressing the left and right sides of the bag opening between the sleeve and the clamping plate. At the same time, the central round opening of the bag opens and connects to the sleeve. The gaps on the front and back sides are flattened by the clamping plate, which improves the sealing of the bag opening when filling and reduces dust. Attached Figure Description

[0031] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0032] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-7 A powder coating bagging device for reducing dust emission includes a turntable 1, the center of which is connected to an external drive device, which is an external motor. The upper part of the turntable 1 is provided with a feeding clamping assembly 3 for feeding powder coating and clamping and sealing the bag. The feeding clamping assembly 3 includes a lifting feeding assembly 31 and a clamping and sealing assembly 32. The lifting feeding assembly 31 is located on the rear side of the turntable 1, and two sets of clamping and sealing assemblies 32 are symmetrically installed at the lower end of the lifting feeding assembly 31. The upper end of the turntable 1 is provided with a bag opening and fixing assembly 2 for adsorbing, fixing and opening the bag. The bag opening and fixing assembly 2 has three sets and is evenly distributed around the axis of the turntable 1.

[0033] When this utility model is in use, the bag opening and fixing component 2 adsorbs and fixes the bag containing powder and opens it. The clamping and sealing component 32 is driven by the lifting and unloading component 31 to rotate and clamp and move downward, extending the position of the unloading pipe, sealing the upper end of the bag and fixing it at the unloading port. The lifting and unloading component 31 simultaneously performs dust suction. The three sets of bag opening and fixing components 2 realize multi-station bag support, which facilitates rapid filling.

The upper end of the support plate 23 has a slide groove 24. The cylinder 25 is fixedly installed on the upper end of the support plate 23. The slide plate 21 closer to the cylinder 25 is fixedly connected to the output end of the cylinder 25 and slidably connected to the inner wall of the slide groove 24. The slide plate 21 farther away from the cylinder 25 is fixedly connected to the inner wall of the slide groove 24. The suction cup 22 is connected to an external air extraction device.

[0035] When this utility model is in use, if it is necessary to fix and open the bag, the output end of the cylinder 25 drives the slide plate 21 connected to the cylinder 25 to move along the slide groove 24 to the slide plate 21 on the other side. After only a small gap is left between the two sets of slide plates 21, the bag is placed into the gap. The cylinder 25 continues to drive so that the suction cup 22 abuts against the side wall of the bag. The suction cup 22 is treated by the external air extraction device. At this time, the suction cup 22 adheres to both sides of the bag. The cylinder 25 drives the gap between the slide plates 21 to open the bag opening, realizing the automatic opening of the bag.

[0036] The suction cups 22 are provided in two sets and are respectively distributed on the upper and lower parts of the slide plate 21.

[0037] When this utility model is in use, the upper and lower sets of suction cups 22 pull the bag open, thus effectively opening the feeding port.

[0038] The lifting and unloading assembly 31 includes a bracket 311, a hopper 312, a support plate 313, a motor 314, a suction pipe 315, a sleeve 316, a collar 317, a lead screw 318, and a slide rod 319.

The motor 314 is fixedly installed on the upper end face of the support plate 313. The external pipe of the suction pipe 315 is connected to the vacuum cleaner.

[0039] When this utility model is in use, if powder feeding is required, powder is added from the feeding port of the feeding hopper 312. The powder passes through the feeding port of the feeding hopper 312 and the sleeve 316, and finally enters the bag from the feeding port of the sleeve 316. At the same time, a vacuum cleaner connected to the dust suction pipe 315 removes the dust generated near the bag opening during feeding. If clamping and sealing feeding is required, the output end of the motor 314 drives the lead screw 318 to rotate, and the lead screw 318 moves the clamping and sealing assembly 32. When the front clamping and sealing assembly 32 moves, the collar 317 moves downward, the collar 317 moves downward, the sleeve 316 moves downward, and the collar 317 moves the rear clamping and sealing assembly 32 downward along the slide rod 319. At this time, the sleeve 316 moves downward into the open bag opening, and the clamping and sealing assembly 32 rotates to clamp the bag between the sleeve 316 and the clamping and sealing assembly 32, and the bag opening only leaves a space communicating with the feed port of the collar 317, so as to achieve the sealing and dust prevention of the bag opening when bagging.

[0040] The clamping and sealing assembly 32 includes a slider 321, a first connecting rod 322, a second connecting rod 323, a clamping plate 324, a third connecting rod 325, and a U-shaped plate 326.

One end of connecting rod 323 is hinged to U-shaped plate, and the other end of connecting rod 323 is hinged to clamping plate 324. The opposite side walls of the two sets of clamping plates 324 are in contact with each other. One end of connecting rod 325 is hinged to U-shaped plate, and the other end of connecting rod 325 is hinged to clamping plate 324. There are two sets of connecting rods 322, 323 and 325, which are symmetrically distributed about the center of slider 321. The clamping plate 324 is a semi-circular arc surface.

[0041] When this utility model is in use, if it is necessary to clamp the bag, the motor 314 drives the lead screw 318 to rotate. The lead screw 318 drives the front slider 321 to move down along the U-shaped plate 326. The front slider 321 drives the front connecting rod 322 to move down and move closer together. The front connecting rod 322 drives the clamping plate 324 to move. The clamping plate 324 drives the front connecting rods 323 and 325 to rotate, so that the clamping plate 324 moves closer together and downward. The front slider 321 drives the collar 317 to descend, and the collar 317 drives the rear slider 325 to descend. 21 moves down along the slide bar 319. The slider 321 on the rear side drives the connecting rod 322 on the rear side to move down and move closer to each other. The connecting rod 322 on the rear side drives the clamping plate 324 to move. The clamping plate 324 drives the connecting rod 323 and the connecting rod 325 on the rear side to rotate, so that the clamping plate 324 moves closer to each other and clamps tightly during the downward movement. The left and right sides of the bag opening are pressed between the sleeve 316 and the clamping plate 324. At the same time, the central round opening of the bag opens and connects to the sleeve 316. The gaps on the front and rear sides are flattened by the clamping plate 324, which improves the sealing of the bag opening when filling and reduces dust.
