[0008] Preferably, the cross-section of the elastic plate is L-shaped, and the whole is configured to be a wave shape for deformation. The elastic plate and the bottom plate are both made of elastic material and bend along with the powder feeding belt.

[0009] Preferably, the telescopic assembly also includes a control module and two connecting wires. The control module is fixedly connected to the side wall of the mounting groove and is fixedly connected to the airbag. Two mounting openings are opened in the middle of the airbag. The two connecting wires pass through the two mounting openings respectively. One end of the connecting wire is fixedly connected to the control module, and the other end is fixedly connected to the connecting plate. The connecting wire is used to energize the energized solenoid.

[0010] Preferably, the airbag is made of elastic material and has a plurality of folding grooves on its surface. The airbag is provided with a jet assembly, which is used to spray the gas inside the airbag toward the side of the placement box.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] The terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present invention are only for the convenience of description and are not used to limit the scope of the present invention. Changes or adjustments to their relative relationships should be regarded as the scope of the present invention without substantially changing the technical content.

[0021] Reference Figure 1-Figure 9A powder feeding device for a pipeline anti-corrosion production line includes: a mounting frame 1, a powder feeding belt 2 fixed inside the mounting frame 1, and two limit plates 3 symmetrically fixed on both sides of the mounting frame 1, a plurality of partitions 4 are equidistantly fixedly connected to the powder feeding belt 2, and two mounting grooves are symmetrically provided on both sides of the partition 4; A placement box assembly 5 is provided between two adjacent partitions 4, and the placement box assembly 5 is used to place powder; Two telescopic components 6 are symmetrically arranged inside the installation slot, and the telescopic components 6 include two connecting plates 61, two energized solenoids 62 and an airbag 63. The two energized solenoids 62 are symmetrically fixedly connected between the two connecting plates 61, one side of the connecting plate 61 is fixedly connected to the placement box component 5, and the airbag 63 is arranged on one side of the installation slot close to the side wall; A pushing assembly 7 is provided between the airbag 63 and the limiting plate 3 , and the pushing assembly 7 is used to drive the placement box assembly 5 to vibrate, so as to evenly spread the powder inside the placement box assembly 5 .

[0022] In the embodiment of the application of the above technical solution, the powder to be transported is quantitatively introduced into the multiple placement box assemblies 5 arranged on the powder feeding belt 2. When no power is supplied, the sides of the placement box assemblies 5 are elastically supported and limited by the energized spiral tube and the airbag 63. When the placement box assemblies 5 move with the transmission belt, the pushing assembly 7 between the airbag 63 and the limiting plate 3 pushes the placement box assemblies 5 alternately on both sides, thereby vibrating the powder inside the placement box assemblies 5 and making the powder evenly distributed inside the placement box assemblies 5, thereby facilitating the subsequent thickness adjustment and introduction of the powder.

[0023] The present invention can vibrate the powder during the powder conveying process to make the powder dispersed evenly, thereby improving the accuracy of thickness adjustment.

[0024] The preferred technical solution in this embodiment is: Reference Figure 3-5 , the placement box assembly 5 does not contact the powder feeding belt 2, and the placement box assembly 5 also includes two side plates 51, two fixed plates 52, two elastic plates 53 and a bottom plate 54, the two sides of the fixed plate 52 are respectively fixedly connected to the two connecting plates 61, the two fixed plates 52 are respectively fixedly connected to the middle of the side away from each other of the two side plates 51, the two elastic plates 53 are fixedly connected between the ends of the two side plates 51, and the bottom plate 54 is fixedly connected to the two sides of the side plates 51 and the elastic plates 53, and the two side plates 51, the two fixed plates 52 and the bottom plate 54 form a placement box for placing powder; The cross section of the elastic plate 53 is L-shaped, and the whole is configured to be a wave shape for deformation. The elastic plate 53 and the bottom plate 54 are both made of elastic material and bend along with the powder feeding belt 2 .

[0025] The connected placement box receives the powder, and the placement box is suspended between the two partitions 4, which ensures the overall swing of the placement box during the vibration process. The powder is not placed directly on the powder feeding belt 2, but the placement box is set to reduce the powder being stuck between the powder feeding belt 2 and the limit plate 3. The placement box can reduce the loss of powder during the transfer process. The placement box has a certain depth. During the swinging process, the amount of powder flying out is reduced, thereby avoiding the waste of powder.

[0026] Since the entire placement box needs to vibrate, the elastic plates 53 on both sides can make the two sides of the entire placement box elastically deform. At the same time, the elastic energized solenoid 62 inside can play an elastic supporting role for the placement box, thereby ensuring that the placement box vibrates and resets multiple times between the limit plates 3, and the powder inside the placement box is evenly distributed.

[0027] Reference Figure 6-8 The telescopic assembly 6 further includes a control module 64 and two connecting wires 65. The control module 64 is fixedly connected to the side wall of the mounting groove and is fixedly connected to the airbag 63. Two mounting openings are provided in the middle of the airbag 63. The two connecting wires 65 pass through the two mounting openings respectively. One end of the connecting wire 65 is fixedly connected to the control module 64, and the other end is fixedly connected to the connecting plate 61. The connecting wire 65 is used to energize the energized solenoid 62. The airbag 63 is made of elastic material and has a plurality of folding grooves on its surface. The airbag 63 is provided with an injection assembly 8 for injecting the gas inside the airbag 63 toward the side of the placement box.

[0028] During the powder transportation process, the front half of the powder conveying belt 2 is a vibration section. When the powder passes through the vibration section, the control module 64 does not perform power-on control. The multiple powered solenoids 62 and the multiple connecting wires 65 are used to elastically support and fix the position of the placement box, and can also play a role in deformation reset during the entire vibration process. The second half of the powder feeding belt 2 is used to adjust the thickness of the powder and to accurately control the amount of the powder. At this time, the power is controlled by the control module 64, and the current is introduced into the energized solenoid 62 through the connecting line 65, so that the energized solenoid 62 is energized and contracted. At this time, the connecting line 65 will deform with the deformation of the energized solenoid 62, and the contracted energized solenoid 62 can fix the position of the placement box, thereby avoiding the shaking of the placement box during the thickness adjustment process, and ensuring accurate control of the powder thickness.

[0029] Reference Figure 6-8The jet assembly 8 includes an air pipe 81 and an air outlet strip 82. The air pipe 81 is L-shaped. One end of the air pipe 81 is fixedly connected to the air bag 63 and passes through the side plate 51. The other horizontal end is arranged parallel to the side plate 51. The air outlet strip 82 is fixedly connected to the bottom of the air pipe 81. A sealing sheet is arranged inside the air outlet strip 82. An air intake assembly 9 is provided between the air bag 63 and the connecting plate 61, and the air intake assembly 9 is used to inflate the air bag 63; The air inlet assembly 9 includes a sealing strip 91 and an air inlet 92 . The air inlet 92 starts at a side of the airbag 63 close to the connecting plate 61 . The sealing strip 91 is fixedly connected to the connecting plate 61 and is used for squeezing and sealing the air inlet 92 .

[0030] During the feeding process, some powder will accumulate on the bottom edge of the placement box. When the powder is exported, the powder accumulated on the bottom edge of the placement box cannot be completely exported, resulting in inaccurate amount of exported powder. It is necessary to export the powder that has not been completely exported to improve the accuracy.

[0031] When the control module 64 controls the energized solenoid 62 to be energized, after the energized spiral tube is energized and expanded, the energized spiral tube is fixedly connected to the fixed plate 52, thereby causing the other end of the energized spiral tube to move toward the fixed plate 52, thereby causing the airbag 63 to be stretched and inflated. When the thickness adjustment is completed and the powder needs to be exported, the control module 64 is powered off, so that the energized spiral tube is reset under the action of its own elastic force. During the resetting process of the energized solenoid 62, the airbag 63 will be squeezed through the connecting plate 61, thereby squeezing the gas inside the airbag 63 into the air pipe 81. When the gas inside the air pipe 81 increases, the internal pressure will increase, thereby squeezing the sealing strip 91 inside the air outlet strip 82, so that the excess gas is ejected from the position of the air outlet strip 82, and the ejected gas will impact the bottom edge of the placement box, thereby dispersing the powder accumulated inside the bottom edge, ensuring that the powder is completely exported during the export process, thereby reducing the waste of powder.

[0032] During the entire process of inflation and air conduction, when no electricity is supplied, the energized solenoid 62 itself has elasticity, thereby squeezing the airbag 63, so that the sealing strip 91 is sealed and blocked at the air inlet 92; When the energized solenoid 62 starts to be energized, the energized solenoid 62 contracts toward the connection plate 61. During the contraction of the energized solenoid 62, the connection plate 61 moves toward the connection plate 61 along with the energized solenoid 62. However, since the airbag 63 needs to be inflated during the recovery process, the airbag 63 is temporarily separated from the connection plate 61, thereby separating the sealing strip 91 from the air inlet 92, and the airbag 63 is inflated through the air inlet 92. After the power is finally cut off, the energized solenoid 62 is elastically reset and squeezes the connecting plate 61. At this time, the sealing strip 91 seals the air inlet 92. The connecting plate 61 squeezes the airbag 63 to squeeze the gas inside the airbag 63 into the air pipe 81, thereby dispersing the powder.

[0033] The L-shaped air pipe 81 is located at the bottom of the placement box, and some paddles can be provided at the end to ensure that the powder can be moved during the vibration process, thereby enhancing the dispersion effect of the powder.

[0034] Reference Fig. 9 The pushing assembly 7 includes a plurality of push rods 71 ​​and a plurality of push rods 72, wherein the push rods 71 ​​are vertically fixedly connected to the bend of the jet assembly 8, and the plurality of push rods 72 are fixedly connected to the limiting plates 3 on both sides, and the push rods 72 are arranged at the feeding end of the powder conveying belt 2; The push rod 71 is cylindrical, and the ends of the plurality of push rods 72 are arranged in a circular shape and are used to push the push rod 71 . The plurality of push rods 72 on both sides are arranged in a staggered manner and are used to push the push rod 71 in a staggered manner.

[0035] After the powder is introduced into the placement box, the powder will be partially accumulated inside the placement box due to the introduction. When the powder moves with the powder feeding belt 2, the multiple push rods 71 ​​inside the placement box will contact the push rods 72 on both sides in a staggered manner, thereby driving the placement box to vibrate evenly, thereby shaking the powder inside the placement box evenly, avoiding affecting the subsequent thickness adjustment.

[0036] The contact ends of the push rod 71 and the push rod 72 are both set to be round, which can reduce the impact and friction generated during contact, thereby achieving a stable vibration effect.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
