Description

TECHNICAL FIELD

[0001] The utility model relates to an automatic powder spraying system, in particular to a large cyclone type automatic powder spraying system. BACKGROUND

[0002] ‌The large cyclone powder spraying system is a kind of efficient powder spraying equipment, mainly used for powder spraying and recovery in industrial coating process. It is especially suitable for the spraying needs of large quantities of workpieces, can efficiently complete the spraying task, and has the functions of rapid color changing and efficient powder recovery.

[0003] The working principle of the large cyclone powder spraying system is to form a certain negative wind speed in the powder spraying chamber through the forced action of the induced draft fan, and to introduce the powder not coated into the recovery system. Through the rotation and separation of the large cyclone, the relatively coarse powder settles into the lower recovery powder barrel, and after screening treatment, it enters the main powder supply barrel for secondary powder spraying. The common screening treatment method is to use a vibrating screen machine for treatment.

[0004] The vibrating screen machine realizes rapid screening by driving the filter screen to vibrate at high frequency and small amplitude; under the action of vibration, fine powder is filtered through the filter screen and enters the lower secondary recovery powder barrel; larger particles are isolated on the filter screen; after long-term work, a large number of larger dust particles will adhere to the filter screen of the vibrating screen machine; these particles will block the filter screen, reducing the filtering efficiency of the vibrating screen machine, and over time, even the efficiency of the large cyclone separation will be reduced, which is not conducive to the control of production cost.‌‌‌‌ UTILITY MODEL CONTENTS

[0044] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0045] Please refer to Figures 1-9 As an embodiment of the utility model, the large cyclone type automatic powder spraying system comprises a powder box 1 and a powder spraying chamber 2 arranged on the powder box 1.

[0046] A plurality of groups of nozzles 202 and powder falling boxes 203 are fixedly installed in the powder spraying chamber 2, the powder box 1 and the nozzles 202 are communicated through a powder inlet pipeline 101, and a rack 201 is rotatably installed on the powder spraying chamber 2.

[0047] A cyclone flow divider 3 is further arranged on the powder box 1, the cyclone flow divider 3 and the powder falling box 203 are communicated through an air inlet pipeline 301, a dust collection box 4 is fixedly connected to the bottom of the cyclone flow divider 3, and the dust collection box 4 and the nozzles 202 are communicated through a backflow pipeline 404.

[0048] The dust collecting box 4 is provided with a filtering mechanism; the filtering mechanism comprises a first filter screen 6 and a second filter screen 7 for intercepting large-particle dust; the first filter screen 6 and the second filter screen 7 are slidingly embedded; and the filtering mechanism can drive the first filter screen 6 and the second filter screen 7 to reciprocatingly rotate.

[0049] In the embodiment, the parts are fixedly installed on the material rack 201, the material rack 201 can drive the parts to move from one side to the other side of the powder spraying chamber 2; during the movement, the powder box 1 can deliver powder and ink through the powder inlet pipeline 101 and the nozzle 202, and the nozzle 202 can uniformly spray the powder and ink on the parts.

[0050] During the powder spraying process, the excessive powder and ink can fall into the powder falling box 203, and the air inlet pipeline 301 is provided with a blower; the powder and ink in the powder falling box 203 can be sucked into the air inlet pipeline 301 and discharged to the cyclone flow divider 3.

[0051] The airflow discharged from the air inlet pipeline 301 spirally flows downward in the cyclone flow divider 3; the powder and ink in the airflow can contact the inner wall of the cyclone flow divider 3 under the action of centrifugal force and slide along the inner wall into the dust collecting box 4, and the remaining air can be discharged to the atmosphere.

[0052] The first filter screen 6 and the second filter screen 7 can filter the powder and ink particles with relatively large particles, so as to prevent the powder and ink from blocking the nozzle 202 during secondary use.

[0053] The filtering mechanism drives the first filter screen 6 and the second filter screen 7 to reciprocatingly rotate, so as to accelerate the filtering efficiency and simultaneously move the powder and ink with relatively large particles to one side of the dust collecting box 4, thereby preventing the powder and ink particles from hindering the powder and ink from passing through the filter screen after long-time work, and further improving the filtering efficiency.

[0054] The powder and ink filtered by the filtering mechanism are collected on the nozzle 202 through the reflux pipeline 404 for subsequent powder spraying, so as to improve the utilization rate of the powder and ink and be beneficial to the control of production cost.

[0055] As a further scheme of the utility model, the air inlet pipeline 301 and the cyclone flow divider 3 communicate along the tangential direction of the cyclone flow divider 3; the cyclone flow divider 3 is fixedly installed with a flow divider pipeline 303 and an exhaust pipeline 302; and the flow divider pipeline 303 and the exhaust pipeline 302 communicate.

[0056] In the embodiment, the airflow in the air inlet pipeline 301 enters along the tangential direction of the cyclone flow divider 3; at this time, the airflow becomes spiral downward airflow; during the rotation of the airflow, the mixed powder and ink can move to the inner wall of the cyclone flow divider 3 under the action of centrifugal force and slide downward along the inner wall to the dust collecting box 4; and the remaining relatively clean airflow flows to the exhaust pipeline 302 through the flow divider pipeline 303 and is discharged to the atmosphere by the exhaust pipeline 302.

[0057] The powder ink can be effectively separated from the airflow by the cyclone separator 3, the separation efficiency is high, and the separated powder ink does not affect secondary use.

[0058] As a further scheme of the utility model, the dust collecting box 4 is fixedly installed with a motor 8; the output end of the motor 8 is fixedly installed with a first driving pulley 801; the dust collecting box 4 is rotatably installed with a first rotating shaft 9, a second rotating shaft 10 and a third rotating shaft 11; the first rotating shaft 9 is fixedly installed with a second driving pulley 901 and a first speed reduction small pulley 902; the first driving pulley 801 and the second driving pulley 901 are connected through a belt; the second rotating shaft 10 is fixedly installed with a first speed reduction large pulley 1002 and a second speed reduction small pulley 1001; the first speed reduction small pulley 902 and the first speed reduction large pulley 1002 are connected through a belt; the third rotating shaft 11 is fixedly installed with a second speed reduction large pulley 1101; the second speed reduction small pulley 1001 and the second speed reduction large pulley 1101 are connected through a belt.

[0059] In the embodiment, the motor 8 is started; thereby driving the first driving pulley 801 to rotate, and driving the second driving pulley 901 and the first rotating shaft 9 to rotate through the belt.

[0060] The rotating first rotating shaft 9 drives the second rotating shaft 10, the first speed reduction large pulley 1002 and the second speed reduction small pulley 1001 to rotate through the first speed reduction small pulley 902, and drives the second speed reduction large pulley 1101 and the third rotating shaft 11 to rotate.

[0061] Through the cooperation of the first speed reduction small pulley 902 and the first speed reduction large pulley 1002 and the second speed reduction small pulley 1001 and the second speed reduction large pulley 1101, the rotating speed of the third rotating shaft 11 is far less than that of the first rotating shaft 9; thereby reducing the burden of the equipment operation, and avoiding reducing the service life of the equipment due to high frequency operation.

[0062] As a further scheme of the utility model, the dust collecting box 4 is fixedly installed with a motor 8; the output end of the motor 8 is fixedly installed with a first driving pulley 801; the dust collecting box 4 is rotatably installed with a first rotating shaft 9, a second rotating shaft 10 and a third rotating shaft 11; the first rotating shaft 9 is fixedly installed with a second driving pulley 901 and a first speed reduction small pulley 902; the first driving pulley 801 and the second driving pulley 901 are connected through a belt; the second rotating shaft 10 is fixedly installed with a first speed reduction large pulley 1002 and a second speed reduction small pulley 1001; the first speed reduction small pulley 902 and the first speed reduction large pulley 1002 are connected through a belt; the third rotating shaft 11 is fixedly installed with a second speed reduction large pulley 1101; the second speed reduction small pulley 1001 and the second speed reduction large pulley 1101 are connected through a belt.

[0063] In this embodiment, when the first rotating shaft 9 rotates, the first rotating rod 12 is driven to rotate, thereby driving the first protruding column 1201 to rotate synchronously.

[0064] When the first connecting rod 602 performs the lifting action, the first filter screen 6 is driven to perform the lifting action synchronously through the connecting plate 601, in this process, the first filter screen 6 drives the sliding block 5 to reciprocate on the guide rail 401, in the sliding process, the first filter screen 6 is in rotating cooperation with the sliding block 5, and the second filter screen 7 is in rotating cooperation with the dust collecting box 4, and in this process, the first filter screen 6 is in sliding cooperation with the second filter screen 7, so as to increase the filtering area of the filter screen.

[0065] The filtering mechanism drives the first filter screen 6 and the second filter screen 7 to reciprocate, so as to accelerate the filtering efficiency, and meanwhile, the relatively large powder ink can be moved to one side of the dust collecting box 4, so as to prevent the powder ink from being blocked when passing through the filter screen after long time working, thereby further improving the filtering efficiency.

[0066] As a further scheme of the utility model, the dust collecting box 4 is provided with a slot 402 and an opening and closing slot 403, the opening and closing slot 403 is slidably embedded with a baffle 16, and the dust collecting box 4 is fixedly installed with a sundry box 17.

[0067] In this embodiment, the baffle 16 can slide up and down in the opening and closing slot 403, so as to open or block the dust collecting box 4 and the sundry box 17, when the dust collecting box 4 and the sundry box 17 are in the open state, the powder ink particles accumulated on one side of the dust collecting box 4 can be moved into the sundry box 17, so as to avoid that the powder ink particles are accumulated too much in the dust collecting box 4 after long time working, thereby reducing the efficiency of the powder ink passing through the filter screen.

[0068] As a further scheme of the utility model, the third rotating shaft 11 is fixedly installed with a driving wheel 13, the sundry box 17 is rotatably installed with a driven wheel 14 matched with the driving wheel 13, the driven wheel 14 is fixedly connected with a second rotating rod 15, the second rotating rod 15 is fixedly installed with a second protruding column 1501, the baffle 16 is fixedly installed with a second connecting rod 1601, and the second connecting rod 1601 is provided with a second sliding slot 1602 slidably embedded with the second protruding column 1501.

[0069] In this embodiment, the driving wheel 13 and the driven wheel 14 form a "Maltese cross movement" structure.

[0070] The third rotating shaft 11 drives the driving wheel 13 to rotate synchronously, and when the driving wheel 13 rotates one circle, the driven wheel 14 rotates one fourth of a circle.

[0071] When the driven wheel 14 rotates, the second rotating rod 15 is rotated to drive the second protruding column 1501 to rotate; when the second protruding column 1501 rotates, the second connecting rod 1601 is driven to make reciprocating lifting action, and the second protruding column 1501 and the second sliding groove 1602 are in sliding fit.

[0072] During the reciprocating lifting movement of the second connecting rod 1601, the baffle 16 slides up and down in the opening and closing groove 403 to guide the dust collecting box 4 and the garbage box 17 to be communicated or blocked.

[0073] That is, the baffle 16 is reset after the active wheel 13 and the driven wheel 14 cooperate four times. During the process, when cooperating for the first time, the baffle 16 moves downward to open the dust collecting box 4; when cooperating for the second time, the baffle 16 moves upward to close the dust collecting box 4; when cooperating for the third time, the baffle 16 continues to move upward, and the dust collecting box 4 is still in the closed state; when cooperating for the fourth time, the baffle 16 moves downward to complete the reset, and the dust collecting box 4 is still in the closed state.

[0074] When the dust collecting box 4 and the garbage box 17 are in the communicated state, the powder and ink particles accumulated on one side of the dust collecting box 4 are moved into the garbage box 17, so that the powder and ink particles accumulated in the dust collecting box 4 for a long time are avoided to reduce the efficiency of the powder and ink passing through the filter screen.

[0075] With the passage of time, the powder and ink particles in the garbage box 17 will be more and more, and the garbage box 17 can be cleaned by a tool, and since it does not directly contact the filter structure, it is not necessary to stop during the cleaning process, and the production efficiency can be effectively improved.

[0076] As a further scheme of the utility model, the exhaust pipeline 302 is communicated with the atmosphere.

[0077] In the embodiment, the gas flow containing a small amount of powder and ink or not containing powder and ink separated by the cyclone separator 3 is discharged to the atmosphere through the exhaust pipeline 302, so that the gas flow is avoided to be accumulated in the room to increase the protection cost.

[0078] The above embodiments are exemplary but not restrictive, so that the technical scheme of the utility model can be realized in other specific forms without departing from the spirit or basic characteristics of the utility model, and all the technical schemes are included in the utility model.
