Description

Technical Field

[0001] The invention relates to the technical field of workpiece spraying, and in particular to a double-channel powder collecting device used in a powder spraying room. Background Art

[0002] The powder spraying room is an important part of the powder coating process, which is mainly used to spray the workpiece with powder evenly and efficiently.

[0003] During the spraying process, a large amount of spray powder will not be sprayed on the parts. A large amount of spray powder will be suspended in the air in the powder room, but will diffuse in the air and adsorb on other structures. After a long time, the spray powder will agglomerate and can only be cleaned regularly and processed centrally, resulting in a large waste of spray powder.

[0004] For example, the spray powder collection device and vacuum spraying equipment for aviation parts provided by authorization announcement No. CN114042578B collects spray powder through the gaps between multiple inclined dust collecting plates, and the dust collecting plates are arranged to face the spraying direction of the spray powder. When the spray powder with impact force in a vacuum state collides with the surface of the dust collecting plate, part of the kinetic energy of the spray powder can be absorbed by the dust collecting plate, and the spray powder can be rebounded to the surface of another adjacent dust collecting plate, and part of the kinetic energy of the spray powder can be absorbed again by the other dust collecting plate. In this way, the kinetic energy of the spray powder is rebounded and absorbed by the two adjacent dust collecting plates, thereby greatly reducing the momentum of the spray powder, and then the spray powder can fall into the dust collecting box at the bottom of the bracket by gravity when it reaches the back plate, effectively preventing the spray powder from floating and diffusing under the spraying impact force of the spray gun, thereby realizing the collection of the spray powder. Secondly, in the process of collecting spray powder, part of the spray powder can be rebounded by the dust collecting plate and returned to the original path, colliding with the incoming spray powder to offset the force and then slide down; part of the spray powder can be refracted and rebounded and collided with the incoming spray powder of different levels to offset the force and then slide down; through continuous refraction and reflection, the spray powder forms a vortex between two adjacent dust collecting plates, so as to drive other suspended spray powder to hit the dust collecting plate, and then slide down along the dust collecting plate and the back plate, so as to achieve the purpose of reducing and collecting the spray powder scattered in the furnace body.

[0005] It has major drawbacks: during use, the dust that enters between the upper and lower adjacent dust collecting plates collides with each other, causing the force to cancel out and then slide downward. The mutual collision between the dust collecting plates and the dust alone has a poor effect on absorbing the kinetic energy of the dust. At the same time, during the rotation of the dust collecting plates, the dust will be hit, causing the dust to change its trajectory and fall and accumulate on the bottom side of the furnace body. Summary of the invention

[0006] The embodiment of the present application provides a dual-channel powder collection device for a powder spraying room, which solves the problem in the prior art that dust entering between two adjacent upper and lower dust collecting plates is offset by mutual collision and then slides downward. The mutual collision between the dust collecting plate and the dust alone has a poor effect on absorbing the kinetic energy of the dust. At the same time, during the rotation of the dust collecting plate, the dust will be hit, causing the dust to change its trajectory and fall and accumulate on the bottom side of the furnace body.

At the same time, the wavy shape makes the upper and lower sides of the dust collecting piece both in an arc shape. When the powder hits, its rebound direction can be changed, and the impact direction of the impact on other powder can be changed, thereby improving the absorption effect of the powder kinetic energy.

[0023] Embodiment 1: Figure 1-Figure 5 As shown, the present application is a dual-channel powder collection device for a powder spraying room, comprising a protective component 100 and a rotating component 200; The protection assembly 100 includes a powder spraying room 110 and a grid frame 160, wherein the grid frame 160 is fixed in the powder spraying room 110, and the rotating assembly 200 includes a rotating table 210, a motor 220 and a collecting plate 260; The rotating platform 210 is cylindrical and fixed to the output end of the motor 220. The motor 220 is fixed to the upper side of the grid frame 160. The rotation axis of the motor 220 is perpendicular to the ground. The axis of the rotating platform 210 and the rotation axis of the motor 220 are on the same straight line. The collecting plate 260 is in the shape of a rectangular parallelepiped with a hollow interior.

There are a plurality of collecting plates 260, which are evenly spaced and distributed in a ring shape. One end of the collecting plate 260 close to the axis of the rotating table 210 is fixed together. The plurality of collecting plates 260 divide the upper side of the rotating table 210 into a plurality of separate processing areas; It also includes a collection assembly 300, wherein the collection assembly 300 includes a dust collecting member 310; The dust collecting member 310 is wavy in shape, and the dust collecting member 310 is located in the cavity of the collecting plate 260; The wave extension direction of the dust collecting member 310 is perpendicular to the axis of the rotating table 210. The two ends of the wave extension direction of the dust collecting member 310 are fixed to the two sides of the inner wall of the cavity of the collecting plate 260. The dust collecting member 310 is inclined at 40-50 degrees. There are multiple dust collecting members 310, and they are evenly spaced along the axis direction of the rotating table 210. The protection assembly 100 further includes an opening 111, an opening 2 112, an electric slide 120, a spray gun 130, a protection door 140 and a storage box 150; The powder spraying room 110 has an opening 111 and an opening 112 on the same side, the opening 112 is located below the opening 111, the protective door 140 is arranged in the opening 111, the protective door 140 is a double-opening door, the storage box 150 is located at the bottom side of the powder spraying room 110, the storage box 150 is slidably connected to the opening 112, and the storage box 150 is located below the grid frame 160; The length direction of the electric slide 120 is perpendicular to the ground. The electric slide 120 is fixed on a side of the powder spraying room 110 away from the opening 111. The spray gun 130 is fixed on a slider of the electric slide 120. The input end of the spray gun 130 is connected to a powder box. The rotating assembly 200 further includes a second motor 230, a turntable 240, a clamping claw 250 and a feed port 261; The number of the second motors 230 is consistent with the number of processing areas separated by the plurality of collecting plates 260, and they correspond one to one. The second motors 230 are fixed to the upper side of the rotating table 210, and the rotation axis of the output end of the second motor 230 is parallel to the rotation axis of the rotating table 210. The number of the turntables 240 is the same as that of the second motor 230, and they correspond one to one. The turntables 240 are cylindrical, and the turntables 240 are fixed to the output end of the second motor 230, and the axis of the turntable 240 is on the same straight line as the rotation axis of the second motor 230. The number of the clamping claws 250 is consistent with the number of the turntables 240 and corresponds one to one. The clamping claws 250 are fixed on the upper side of the turntable 240; The clamping claw 250 is used to clamp the workpiece, and the output end of the spray gun 130 faces the workpiece clamped by the clamping claw 250; The collecting plate 260 has a feed inlet 261 on one side, and the plurality of dust collecting members 310 are located in the feed inlet 261; The end of the dust collecting member 310 away from the feed inlet 261 is tilted downward; The vertical projections of two adjacent dust collecting members 310 on the side of the collecting plate 260 away from the feed port 261 overlap by two thirds; The clamping claw 250 and the spray gun 130 are prior art and will not be described in detail here.

[0024] During use, the spray gun 130 is connected to the negative electrode, and a high-voltage electrostatic field is generated under the action of the high-voltage electrostatic generator at the front end of the spray gun 130. The workpiece to be sprayed is grounded and used as the positive electrode. The workpiece to be sprayed is clamped by the clamping claw 250, and the motor 220 drives the rotating table 210 to rotate, and the motor 230 drives the rotating table 240 to rotate together. When the workpiece reaches the position facing the output end of the spray gun 130, the motor 220 stops rotating, and the spray gun 130 sprays out powder. Due to corona discharge, dense charges are generated near it. When the powder is sprayed from the gun nozzle, a loop is formed to form charged paint particles. These charged particles are attracted to the workpiece with the opposite polarity due to the electrostatic force. After the spraying of a workpiece surface is completed, the motor 220 continues to rotate and rotates the next workpiece to the position facing the spray gun 130. At the same time, the spray gun 130 can adjust the height position through the electric slide 120. During the rotation of the motor 220, the side of the opening of the collecting plate 260 faces the front of the rotation. During the processing, when the motor 220 drives the turntable 240 to rotate, the remaining excess powder is collected by the collecting plate 260 and the dust collecting piece 310. During the rotation of the turntable 210, the powder enters between two adjacent dust collecting pieces 310. When the powder hits the lower side of the dust collecting piece 310 located above, it rebounds to the upper side of the dust collecting piece 310 below, thereby rebounding back and forth between the two adjacent dust collecting pieces 310 and absorbing the kinetic energy of the sprayed powder, greatly reducing the momentum of the sprayed powder, so that the powder When not hitting the dust collecting piece 310, it can rely on gravity to fall to the bottom side of the collecting plate 260 at the bottom of the bracket. At the same time, during the rebound of the powder, it can hit other powders, causing collision and offsetting the force, and then slide down; during the rotation of the collecting plate 260, due to the action of centrifugal force, the powder can also hit the inclined side of the wavy dust collecting piece 310, thereby improving the energy absorption effect; the powder not collected by the collecting plate 260 can fall through the grid frame 160 into the storage box 150 for collection.

[0025] Compared with the prior art, by making the dust collecting piece 310 wavy, the incoming powder can also hit the inclined side of the wavy dust collecting piece 310 during the rotation of the collecting plate 260, thereby improving the kinetic energy absorption effect of the powder. At the same time, the wavy shape makes the upper and lower sides of the dust collecting piece 310 present an arc-shaped state. When the powder hits, its rebound direction can be changed, and the impact direction of other powders can be changed, thereby improving the absorption effect of the powder kinetic energy. At the same time, the residual powder in the powder spraying room 110 is collected in two channels through the collecting component 300 and the storage box 150, thereby improving the collection effect.

[0026] Embodiment 2: When the embodiment 1 is in use, the dust collecting member 310 is made into a wave shape to improve the absorption effect of the kinetic energy of the powder. However, during use, the absorption effect of the kinetic energy of the powder by the impact of the powder itself and the absorption of the kinetic energy by the impact of the powders is low, thereby reducing the powder collection efficiency. Based on this, the solution of the embodiment 1 is improved, such as Figure 6-Figure 9 As shown: The dust collecting member 310 includes a fixing plate 311, a supporting plate 312 and an elastic membrane 313; The fixing plate 311 is wavy, and both ends of the fixing plate 311 in the wavy extension direction are fixed in the feed port 261; The support plate 312 is arc-shaped, the number of the support plates 312 is consistent with the number of the wave crests of the fixed plate 311, and they correspond one to one. One end of the support plate 312 in the length direction is fixed to one side of the wave crest of the fixed plate 311. The support plate 312 is located on the side of the fixed plate 311 away from the opening of the feed port 261. The axis of the support plate 312 is perpendicular to the length direction of the fixed plate 311. The two support plates 312 at both ends of the wave extension direction of the fixed plate 311 are fixed to the inner wall of the cavity of the collecting plate 260 at their sides away from each other. The elastic membrane 313 is arc-shaped, and the elastic membrane 313 is hollow inside. The number of the elastic membranes 313 is consistent with the number of the troughs of the fixed plate 311, and they correspond one to one. One end of the elastic membrane 313 in the length direction is fixed to one side of the trough of the fixed plate 311. The elastic membrane 313 and the support plate 312 are located on the same side of the fixed plate 311. The axis of the elastic membrane 313 is parallel to the axis of the fixed plate 311. The elastic membrane 313 is located between two adjacent support plates 312, and the two ends of the arc of the elastic membrane 313 are respectively fixed to the support plates 312 on both sides. The elastic membrane 313 is made of rubber; The support plate 312 has an air pipeline inside, and the air pipeline inside the support plate 312 connects the multiple elastic membranes 313; The collection assembly 300 also includes an air pump assembly 320; The number of the air pump groups 320 is consistent with the number of the dust collecting parts 310 and corresponds one to one. The air pump groups 320 are fixed on the side of the collecting plate 260 away from the axis of the rotating table 210. The air pump group 320 is equipped with an air pump, and the output end of the air pump is connected to the air supply pipeline in the support plate 312.

[0027] During use, the elastic membrane 313 may be deformed under the action of the centrifugal force during the rotation of the collecting plate 260, and may disturb the powder entering therein. When it stops suddenly, the elastic membrane 313 may also swing. The elastic membrane 313 is made of a hollow rubber material inside, and is intermittently inflated and deflated by the air pump in the air pump group 320. The inflation and expansion can change the rebound path of the powder and shorten the rebound path. At the same time, the material is softer and can absorb more energy of the powder when it impacts. At the same time, after long-term use, the intermittent inflation and expansion of the elastic membrane 313 can shake off the dust on its surface.

[0028] During the rotation of the entire device, due to the centrifugal force, the elastic membrane 313 can be deformed to disturb the dust entering it, thereby improving the effect of absorbing its kinetic energy; the elastic membrane 313 made of rubber material can absorb part of the impact force of the powder when the powder hits it; at the same time, the elastic membrane 313 can be intermittently inflated, and the inflated elastic membrane 313 can change the rebound path of the powder, shorten the rebound path, and improve the powder collection effect; intermittent inflation can make the dust attached to the surface fall off, thereby improving the cleaning effect.

[0029] Embodiment 3: When the embodiment 2 is used, the air pump in the air pump group 320 is used to inflate the elastic membrane 313, so that the elastic membrane 313 expands. On this basis, the elastic membrane 313 can also be improved to improve the effect of collecting powder and its energy consumption. Based on this, the solution of the embodiment 2 is improved, such as Fig.10 As shown: The dust collecting member 310 further includes a partition group, the number of the partition groups is consistent with the number of the elastic membranes 313, and the partition groups are one-to-one corresponding, the partition groups are located in the cavity of the elastic membrane 313, the partition groups include a plurality of diaphragms 314, and the length direction of the diaphragms 314 is perpendicular to the length direction of the elastic membrane 313; The plurality of diaphragms 314 are fixed on the inner wall of the elastic membrane 313, and the plurality of diaphragms 314 divide the cavity of the elastic membrane 313 into a plurality of cavities that are not connected to each other along its length direction; The diaphragm 314 is made of rubber; The number of the gas delivery pipelines in the support plate 312 and the number of the cavities of the elastic membrane 313 separated by the diaphragm 314 are consistent and correspond one to one; The number of air pumps in the air pump group 320 is consistent with the number of air delivery pipelines in the support plate 312 and corresponds one to one.

[0030] During use, the air pump in the air pump group 320 can change the inflation volume of the multiple cavities when inflating the multiple cavities divided by the diaphragm 314 in the elastic membrane 313. The inflation volume of the cavities closer to one end of the fixed plate 311 is smaller, so that the channel between the upper and lower adjacent elastic membranes 313 appears to be expanded. When the powder enters the expanded channel, the rebound path gradually shrinks, reducing the length of the powder rebound path and improving the kinetic energy absorption effect of the dust.

[0031] By dividing the internal cavity of the elastic membrane 313 into multiple parts and filling different positions with different amounts of gas, different amounts of expansion are generated, so that the interval between the upper and lower adjacent elastic membranes 313 is gradually reduced, and the channel between them forms a flared shape. When powder enters, the rebound path gradually becomes smaller, thereby improving the kinetic energy absorption effect of dust and improving the powder collection efficiency.

[0032] Embodiment 4: When the embodiment 3 is in use, the interval between the upper and lower adjacent elastic membranes 313 is gradually reduced, and the channel between them is expanded to improve the energy absorption effect of the powder. However, the elastic membrane 313 can only swing by the centrifugal force generated when the collecting plate 260 rotates. The absorption of the internal powder kinetic energy can be further improved to improve the absorption effect of the powder kinetic energy. Based on this, the solution of the embodiment 3 is improved, such as Figure 11-Figure 14 As shown: The middle part of the support plate 312 is an electromagnet, the length direction of the electromagnet in the middle part of the support plate 312 is parallel to the length direction of the support plate 312, and the length of the electromagnet in the middle part of the support plate 312 is consistent with the length of the support plate 312; The dust collecting member 310 further includes an adsorption group, the number of which is consistent with the number of the elastic membranes 313 and corresponds one to one, and the adsorption group includes a plurality of iron balls 315; The iron balls 315 are fixed in the lower side wall of the elastic membrane 313, and a plurality of the iron balls 315 are evenly spaced along the length direction of the elastic membrane 313; The support plate 312 is an elastic plate.

[0033] From top to bottom, the electromagnets on the same straight line are energized together. During the energization process, the iron balls 315 on the rubber airbags on both sides can be adsorbed to deform the elastic membrane 313, disturb the powder flowing inside, and absorb its kinetic energy; at the same time, the upper and lower support plates 312 can be brought closer to each other, and the interval between them can be gradually reduced, thereby reducing the rebound path length of the dust again and improving the kinetic energy absorption effect of the dust; at the same time, the swinging can remove the dust attached to the surface of the support plate 312 and the elastic membrane 313; the electromagnets on different straight lines are energized intermittently.

[0034] When the iron ball 315 on the lower side of the expanded elastic membrane 313 is adsorbed by the electromagnet, the overall shape of the elastic membrane 313 can be changed, so that two adjacent elastic membranes 313 are closer to each other, which can shorten the rebound path of the dust between the upper and lower support plates 312 and improve the efficiency of absorbing its kinetic energy; at the same time, after adsorption, the flared position formed between the upper and lower elastic membranes 313 can be changed. In the process of change, the rebound path of the powder in the flared channel can be changed, further consuming and absorbing its kinetic energy.

Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
