DETAILED DESCRIPTION

[0045] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without any creative effort belong to the protection scope of the present application.

[0046] ​​The present application improves the traditional ceramic powder spraying equipment when spraying ceramics. The traditional ceramic powder spraying equipment often sprays single exposed ceramics one by one. However, this spraying work mode can only complete the spraying of one ceramic in one working process. The ceramic needs to be rotated or the position of the coating spray head needs to be adjusted to realize multi-angle spraying of the ceramic. The next ceramic can be sprayed only after the spraying of the current ceramic is completed. Obviously, the traditional spraying equipment prolongs the spraying time of a unit ceramic, thereby reducing the spraying efficiency of the spraying equipment.

[0047] The technical scheme of the present application is as follows: the first motor 21 drives the second disc 3 to rotate, so that the spraying assembly can move synchronously with the conveying belt 1. Thus, the single spraying assembly on the workpiece powder spraying equipment can move synchronously with the single workpiece on the conveying belt 1, so that the single spraying assembly can continuously spray the single workpiece. Meanwhile, the second disc 3 is provided with multiple spraying assemblies and transmission assemblies distributed around the top of the second disc 3, so that the multiple spraying assemblies can alternately spray the multiple workpieces.

[0048] In order to better understand the above technical scheme, the above technical scheme will be described in detail in combination with the drawings and specific embodiments in the specification.

[0049] The present application provides a workpiece powder spraying equipment, which comprises a conveying belt 1 and further comprises:

[0050] The first disc 2 is horizontally placed on a working plane and is provided with a first motor 21 mounted on the surface.

[0051] The second disc 3 is mounted on the output end of the first motor 21.

[0052] The first support 31 is vertically fixed at the center of the second disc 3. The upper end of the first support 31 is provided with uniformly arranged mounting holes. The electric telescopic rod 311 is mounted in the mounting hole.

[0053] The second support 32 is rotatably mounted above the second disc 3 through the support frame 33. One end of the second support 32 is hingedly connected with the electric telescopic rod 311. The other end of the second support 32 is connected with the spraying assembly.

[0054] The spraying assembly is arranged above the conveying belt 1. The spraying unit is used for spraying the workpiece on the conveying belt 1.

[0055] The transmission assembly is located on one side of the spraying assembly and is used for providing power for the movement of the spraying assembly.

[0056] The first motor 21 is fixedly installed on the upper surface of the first disc 2, and the second disc 3 is fixedly installed at the output end of the first motor 21, so that the second disc 3 can rotate with the output end of the first motor 21, and the first disc 2 is horizontally placed on the horizontal ground, so that the rotating second disc 3 rotates relative to the working plane, and the first support 31 is vertically fixedly installed at the center of the second disc 3, so that the first support 31 rotates synchronously with the second disc 3, and the mounting holes are uniformly arranged on the upper end of the first support 31, and the electric telescopic rod 311 is fixedly installed in the mounting hole, and the second support 32 is hingedly connected to the output end of the electric telescopic rod 311, so that the second support 32 also rotates with the second disc 3, and the spraying assembly is connected to the end of the second support 32 away from the first support 31, so that the spraying assembly can rotate with the second disc 3, and the spraying assembly is arranged above the conveying belt 1, and the conveying belt 1 is arranged in a semi-annular shape, so that the rotating second disc 3 can move in the same direction as the conveying belt 1, so that the spraying assembly moves in the same direction as the conveying belt 1, and the rotating speed of the spraying assembly is controlled to be the same as the moving speed of the conveying belt 1, and the spraying assembly is located above the conveying belt 1, so that the spraying assembly and the conveying belt 1 are vertically arranged;

[0057] When the workpiece needs to be sprayed, the electric telescopic rod 311 is powered on, so that the output end of the electric telescopic rod 311 can move vertically downward relative to the first support 31, and the end of the second support 32 close to the first support 31 is hingedly connected to the output end of the electric telescopic rod 311, so that the end of the second support 32 close to the first support 31 moves downward with the output end of the electric telescopic rod 311, and the support frame 33 is fixedly installed on the second disc 3, and the upper end of the support frame 33 is hingedly connected to the second support 32, so that when the end of the second support 32 close to the first support 31 moves downward, the end of the second support 32 away from the first support 31 moves upward relative to the first support 31 with the hinged point at the upper end of the support frame 33 as the fulcrum, and the spraying assembly is fixedly installed at the end of the second support 32 away from the first support 31, so that the spraying assembly moves upward synchronously with the end of the second support 32 away from the first support 31, so that the spraying assembly moves upward relative to the conveying belt 1, and the workpiece is placed on the conveying belt 1 below the spraying assembly by artificial or mechanical arm;

[0058] When the workpiece is placed and transported to the spraying assembly position by the conveying belt 1, the output end of the electric telescopic rod 311 is moved upward by controlling the electric telescopic rod 311, the second support 32 is moved upward synchronously by the upward moving output end, and the second support 32 far away from one end of the first support 31 will move downward relative to the first support 31, so that the spraying assembly rotating synchronously with the conveying belt 1 will move downward relative to the conveying belt 1, and the spraying assembly moves downward relative to the conveying belt 1, the workpiece on the conveying belt 1 is covered in the spraying assembly, so that the workpiece is located in the spraying assembly, and the workpiece can be sprayed with powder in the spraying assembly, and since the spraying assembly and the conveying belt 1 rotate in the same direction and at the same speed, the workpiece will be continuously sprayed by the spraying assembly during transportation, and then a plurality of workpieces are sprayed by the plurality of spraying assemblies alternately.

[0059] Compared with the traditional ceramic powder spraying equipment, the ceramic is usually sprayed one by one, but in most cases, the spraying is completed in one work process, and the ceramic needs to be rotated or the position of the coating nozzle needs to be adjusted to realize multi-angle spraying of the ceramic, and the next ceramic cannot be sprayed until the spraying of the ceramic is completed. Obviously, the traditional spraying equipment prolongs the spraying time of the unit ceramic, thereby reducing the spraying efficiency of the spraying equipment.

[0060] The first motor 21 drives the second disc 3 to rotate, so that the spraying assembly can move synchronously with the conveying belt 1, and the single spraying assembly on the workpiece powder spraying equipment can move synchronously with the single workpiece on the conveying belt 1, so that the single spraying assembly can continuously spray the single workpiece, and the plurality of spraying assemblies on the second disc 3 can alternately spray the plurality of workpieces, so that the workpiece on the conveying belt 1 is sprayed during transportation, thereby reducing the spraying time of the unit workpiece of the spraying equipment, and improving the spraying efficiency of the spraying equipment.

[0061] As an embodiment of the present application, the spraying assembly comprises:

[0062] The cover body 4 is hinged to one end of the second support 32 away from the first support 31.

[0063] The storage box 5 is installed on the second disc 3.

[0064] The circular frame 41 is in sliding connection with the inner wall of the cover body 4.

[0065] A material conveying pipe 42 is arranged inside the first support 31, the second support 32 and the cover body 4, one end of the material conveying pipe 42 is communicated with the storage box 5, and the other end is installed above the circular frame 41;

[0066] A plurality of paint spray heads 43 are fixedly installed on the inner wall of the circular frame 41 and connected with the material conveying pipe 42;

[0067] The end, which is communicated with the storage box 5, of the material conveying pipe 42 is fixedly installed with an air pump 44;

[0068] Since the cover body 4 is hinged to the end of the second support 32 away from the first support 31, when the end of the second support 32 away from the first support 31 moves upward relative to the first support 31, the cover body 4 will move upward along with the second support 32, and the upward movement of the cover body 4 will gradually increase the distance between the cover body 4 and the conveying belt 1, and when the upward movement of the cover body 4 is completed, the workpiece is placed on the conveying belt 1 below the spraying assembly by a person or a mechanical arm;

[0069] When the workpiece is placed, the end of the second support 32 away from the first support 31 moves downward relative to the first support 31, so that the cover body 4 moves downward along with the second support 32, and the downward movement of the cover body 4 will gradually decrease the distance between the cover body 4 and the conveying belt 1, and when the downward movement of the cover body 4 is completed, the cover body 4 will enclose the workpiece on the conveying belt 1 in the cover body 4, and the bottom surface of the cover body 4 will contact the surface of the conveying belt 1 to avoid that the powder is sprayed to the outside of the cover body 4 from the gap between the cover body 4 and the conveying belt 1 during spraying, and when the workpiece is located in the cover body 4, the circular frame 41 connected with the cover body 4 in a sliding manner is driven to move by the transmission assembly, so that the circular frame 41 can move upward and downward relative to the cover body 4 in the cover body 4, and then the circular frame 41 can move upward and downward relative to the workpiece, since the circular frame 41 is connected with the cover body 4 in a sliding manner, the circular frame 41 moves upward and downward while being sleeved around the outer surface of the workpiece to be sprayed, and in addition, the plurality of paint spray heads 43 are fixedly installed on the inner wall of the circular frame 41 and connected with the material conveying pipe 42, so that the plurality of paint spray heads 43 can move upward and downward around the outer surface of the workpiece to be sprayed along with the circular frame 41, to facilitate multi-angle spraying of the workpiece;

[0070] In addition, the cover body 4 is hinged to the end of the second support 32 away from the first support 31, so that the cover body 4 can always keep vertical relative to the workpiece when the cover body 4 moves upward and downward along with the second support 32, and then the phenomenon that the cover body 4 collides with the workpiece during upward and downward movement of the cover body 4 is avoided;

[0071] The powder can be stored in the storage box 5, and then the powder in the storage box 5 can be blown into the conveying pipe 42 by high-pressure gas, transported to the coating spray head 43 connected with the conveying pipe 42 through the conveying pipe 42, and sprayed on the workpiece by the coating spray head 43. Since the conveying pipe 42 is located in the first support 31, the second support 32 and the cover 4, the conveying pipe 42 does not affect the movement of the first support 31, the second support 32 and the cover 4.

[0072] As an embodiment of the present application, the circular frame 41 is internally provided with an annular chamber 411;

[0073] As an embodiment of the present application, the conveying pipe 42 is installed on the circular frame 41 and communicated with the annular chamber 411, and the plurality of coating spray heads 43 installed on the inner wall of the circular frame 41 are communicated with the annular chamber 411;

[0074] By internally providing the circular frame 41 with the annular chamber 411 and installing the conveying pipe 42 on the circular frame 41 and communicated with the annular chamber 411, the powder in the storage box 5 can be drawn into the annular chamber 411 from the storage box 5, and then the plurality of coating spray heads 43 installed on the inner wall of the circular frame 41 are communicated with the annular chamber 411, so that the powder in the annular chamber 411 can enter the coating spray head 43, and the coating spray head 43 can spray the powder on the workpiece.

[0075] As an embodiment of the present application, the cover 4 is provided with a through hole 413 on one side, the circular frame 41 is provided with a first transmission rod 412 on one side, and the first transmission rod 412 passes through the through hole 413 and is slidably connected with the through hole 413;

[0076] As an embodiment of the present application, the transmission assembly comprises

[0077] The housing 6 is installed on one side of the cover 4;

[0078] The second motor 61 is installed on the top inside the housing 6;

[0079] The lead screw 62 is placed inside the housing 6 and connected with the output end of the second motor 61 at one end;

[0080] The limiting sliding block 63 is slidably installed on one side of the inner surface of the housing 6 and internally provided with a threaded hole engaged with the lead screw 62.

[0081] The second transmission rod 64 is fixedly connected to the side of the limiting sliding block 63 away from the second motor 61, and the other end of the second transmission rod 64 is fixedly connected to the end of the first transmission rod 412 away from the circular frame 41, and the second transmission rod 64 is slidingly connected to the shell 6;

[0082] As an embodiment of the application, a limiting switch 65 is mounted in the cover body 4, and the limiting switch 65 is located on one side of the limiting sliding block 63;

[0083] When the cover body 4 has covered the workpiece on the conveying belt 1 in the cover body 4, the screw rod 62 is placed in the shell 6 and rotationally connected to the shell 6, and one end of the screw rod 62 is fixedly connected to the output shaft of the second motor 61, so that when the second motor 61 is powered to rotate in the positive direction, the second motor 61 rotating in the positive direction will drive the screw rod 62 in the shell 6 to rotate in the positive direction. Since the limiting sliding block 63 is slidingly installed on one side of the shell 6 and the inner surface of the limiting sliding block 63 is provided with a threaded hole engaged with the screw rod 62, when the screw rod 62 rotates, it will pass through the threaded hole in the inner surface of the limiting sliding block 63 and be in threaded engagement with the limiting sliding block 63. Since one end of the screw rod 62 is fixedly connected to the output shaft of the second motor 61, the position of the screw rod 62 in the shell 6 is fixed relative to the shell 6. Since the position of the screw rod 62 in the shell 6 is fixed relative to the shell 6, and the shell 6 is fixedly installed on one side of the cover body 4, when the screw rod 62 is in threaded engagement with the limiting sliding block 63, only the limiting sliding block 63 slides downward in the shell 6, and then the second transmission rod 64 is slidingly connected to the shell 6, so that the downward sliding limiting sliding block 63 also drives the second transmission rod 64 fixedly connected to the side of the limiting sliding block 63 away from the second motor 61 to move downward. Since the circular frame 41 is provided with the first transmission rod 412 on one side, the first transmission rod 412 is fixedly connected to one side of the circular frame 41, and the other end of the second transmission rod 64 is fixedly connected to the end of the first transmission rod 412 away from the circular frame 41, so the downward moving second transmission rod 64 also drives the circular frame 41 to move downward, and the downward moving circular frame 41 drives the paint spray head 43 being sprayed to move downward, and the downward moving paint spray head 43 sprays the workpiece from top to bottom. Since the paint spray head 43 on the circular frame 41 is multiple, the workpiece can be sprayed from multiple angles from top to bottom;

[0084] When the second transmission rod 64 moves downward to the bottom end inside the shell 6, since the cover 4 is internally provided with a limit switch 65, and the limit switch 65 is located on one side of the limit sliding block 63, at this time, one side of the limit sliding block 63 will touch the limit switch 65, when touching the limit switch 65, the second motor 61 will start to reverse, the reversed second motor 61 will drive the lead screw 62 to reverse, the reversed lead screw 62 will slide the limit sliding block 63 upward inside the shell 6 through the threaded hole in the inner surface of the limit sliding block 63, the upward sliding limit sliding block 63 will also drive the second transmission rod 64 fixedly connected with the limit sliding block 63 to move upward, since the other end of the second transmission rod 64 is fixedly connected with the first transmission rod 412, the upward moving second transmission rod 64 will also drive the first transmission rod 412 to move upward, since the circular frame 41 is provided with the first transmission rod 412 on one side, and the other end of the second transmission rod 64 is fixedly connected with the first transmission rod 412 away from the circular frame 41, the upward moving second transmission rod 64 will also drive the circular frame 41 to move upward, the upward moving circular frame 41 will drive the paint spraying head 43 being sprayed to move upward, the upward moving paint spraying head 43 will perform multi-angle spraying from bottom to top on the workpiece, thereby ensuring the spraying efficiency of the spraying equipment;

[0085] When the second transmission rod 64 moves upward to the top end inside the shell 6, at this time, one side of the limit sliding block 63 will touch the limit switch 65, when touching the limit switch 65, the second motor 61 will reverse again, thereby driving the circular frame 41 to move upward;

[0086] In addition, the cover 4 is provided with a through hole 413 on one side, and the first transmission rod 412 passes through the through hole 413 and is in sliding connection with the through hole 413, so that the end of the first transmission rod 412 fixedly connected with the circular frame 41 can move up and down with the second transmission rod 64 outside the cover 4, thereby ensuring that the circular frame 41 can move up and down with the second transmission rod 64.

[0087] As an embodiment of the present application, the storage box 5 is provided with a liquid injection port 7 above;

[0088] When the powder inside the storage box 5 is close to being used up, at this time, the liquid injection port 7 is provided above the storage box 5 to fill the powder inside the storage box 5, thereby avoiding the phenomenon that the powder inside the storage box 5 is insufficient, thereby ensuring the working efficiency of the spraying equipment.

[0089] As an embodiment of the present application, the cover 4 is fixedly connected with a film 8 inside the upper end, and the film 8 is attached to the inner wall of the cover 4;

[0090] The upper and lower ends of the film 8 are fixedly connected with the upper and lower ends inside the cover body 4 respectively, the middle part of the film 8 is attached to the inner wall of the cover body 4, and the film 8 is arranged as a foldable film 8 (such as an organic silicon PDMS film), so that the workpiece is sprayed in the film 8. On the one hand, the phenomenon that the powder sprayed from the through hole 413 formed in one side of the cover body 4 splashes out of the cover body 4 is avoided, and on the other hand, the stacked elastic film 8 can adapt to the long distance of up and down pulling, so that the up and down movement of the second transmission rod 64 fixedly connected to the circular frame 41 and passing through the film 8 and the circular frame 41 slidingly connected to the inner wall of the cover body 4 and passing through the film 8 is not affected, so that the transmission assembly can work normally and is not affected by the powder.

[0091] As an embodiment of the application, the second support 32, the spraying assembly and the transmission assembly form a working unit, and a plurality of the working units are circumferentially distributed above the second disc 3.

[0092] By forming a working unit of the second support 32, the spraying assembly and the transmission assembly, and circumferentially distributing a plurality of the working units above the second disc 3, the plurality of working units can alternately complete the spraying work of the workpiece transported by the conveying belt 1, the waiting time required after the spraying of a single working unit is completed is reduced, the continuity of the spraying equipment is improved, and the production efficiency of the spraying equipment is improved.

[0093] Working principle: the first motor 21 fixedly installed on the upper surface of the first disc 2 is energized, and the second disc 3 is fixedly installed on the output end of the first motor 21, so that the second disc 3 can rotate with the output end of the first motor 21. The first disc 2 is horizontally placed on the horizontal ground, so the rotating second disc 3 rotates relative to the working plane. Since the first support 31 is vertically fixedly installed at the center of the second disc 3, the first support 31 will rotate synchronously with the second disc 3. The upper end of the first support 31 is circumferentially provided with uniformly arranged mounting holes, and the electric telescopic rod 311 is fixedly installed in the mounting hole. The end of the second support 32 close to the first support 31 is hingedly connected to the output end of the electric telescopic rod 311, so that the second support 32 can also rotate with the second disc 3. Since the spraying assembly is connected to the end of the second support 32 away from the first support 31, the spraying assembly can rotate with the second disc 3. The spraying assembly is arranged above the conveying belt 1, and the conveying belt 1 is arranged in a semi-ring shape, so that the rotating second disc 3 can be consistent with the moving direction of the conveying belt 1, and the spraying assembly is consistent with the moving direction of the conveying belt 1. Then, the rotating speed of the spraying assembly is controlled to be consistent with the moving speed of the conveying belt 1. Since the spraying assembly is above the conveying belt 1, the vertical position of the spraying assembly and the conveying belt 1 is guaranteed.

[0094] When the workpiece needs to be sprayed, at this time the output end of the electric telescopic rod 311 can be moved vertically downward relative to the No. 1 support 31 by energizing the electric telescopic rod 311, since the end of the No. 2 support 32 close to the No. 1 support 31 is hinged to the output end of the electric telescopic rod 311, the end of the No. 2 support 32 close to the No. 1 support 31 will move downward following the output end of the electric telescopic rod 311, since the support frame 33 is fixedly installed on the No. 2 disc 3 and the upper end of the support frame 33 is hinged to the No. 2 support 32, when the end of the No. 2 support 32 close to the No. 1 support 31 moves downward, the end of the No. 2 support 32 away from the No. 1 support 31 will move upward relative to the No. 1 support 31 with the hinged point of the upper end of the support frame 33 as the fulcrum, then the spraying assembly is fixedly installed at the end of the No. 2 support 32 away from the No. 1 support 31, so that the spraying assembly can move upward synchronously with the end of the No. 2 support 32 away from the No. 1 support 31, therefore the spraying assembly will move upward relative to the conveyor belt 1 at this time, and the workpiece is placed on the conveyor belt 1 below the spraying assembly by artificial or mechanical arm;

[0095] When the workpiece is placed and transported to the spraying assembly position by the conveyor belt 1, at this time the output end of the electric telescopic rod 311 is moved upward by controlling the electric telescopic rod 311, the output end moving upward will synchronously drive the end of the No. 2 support 32 close to the No. 1 support 31 to move upward, and in turn the end of the No. 2 support 32 away from the No. 1 support 31 will move downward relative to the No. 1 support 31, so that the spraying assembly rotating synchronously with the conveyor belt 1 will move downward relative to the conveyor belt 1, therefore the spraying assembly moves downward relative to the conveyor belt 1 at this time, the spraying assembly moving downward will enclose the workpiece on the conveyor belt 1 inside the spraying assembly, so that the workpiece is located inside the spraying assembly, and in turn the workpiece can complete multi-angle powder spraying inside the spraying assembly, since the spraying assembly and the conveyor belt 1 rotate in the same direction and at the same speed, the workpiece will be continuously sprayed by the spraying assembly during transportation, and then multiple workpieces are sprayed alternately by multiple spraying assemblies.
