Description

Technical Field

[0001] This invention relates to the field of space frame pole processing technology, specifically to a high-efficiency spraying equipment for space frame poles. Background Technology

[0002] Space frame structures are large-span covered spatial structures formed by connecting multiple space frame rods in a certain grid pattern through nodes. Space frame structures have the advantages of good integrity, high spatial stiffness, and structural stability. They are not only lightweight, require less on-site construction work, and can be constructed quickly, but also have a small height and can make effective use of space. Therefore, they are widely used in the construction industry.

[0003] Because space frame structures can cover planes of various shapes and can be designed into various forms, they are often used for the exterior decoration of buildings, thus requiring high corrosion resistance of the space frame connecting rods and nodes. Spraying has always been a major method and means of surface treatment for space frame connecting rods and nodes. This involves dispersing the paint into a mist and spraying it onto the surface of the space frame connecting rods and nodes. The paint forms a firmly adhered, continuous solid film with a certain strength, which can prevent damage to the surface of the space frame connecting rods and nodes from the external environment and extend their service life.

[0004] The existing space frame connecting rods are mostly painted manually, which results in low painting efficiency, poor coating uniformity, and serious impact on product quality. Furthermore, the painted space frame connecting rods cannot be dried in time, leading to low overall production efficiency. Summary of the Invention

The main support frame 54 is provided with a drive shaft 11 and a driven shaft 12 for rotation between the two shafts 6. Both the drive shaft 11 and the driven shaft 12 are provided with splines to ensure that the support frame 54 can move relative to the drive shaft 11 and the driven shaft 12.

The drive shaft 11 is provided with two drive wheels located in the first transmission gap and the second transmission gap respectively. The driven shaft 12 is provided with two driven wheels located in the first transmission gap and the second transmission gap respectively. A transmission belt 14 is connected between the drive wheels and the driven wheels. The two transmission belts 14 are fixedly connected to the drive transmission box 15 and the driven clamping mechanism 10 respectively.

[0034] In this embodiment, to achieve clamping of the space frame poles, the active clamping assembly includes an active transmission box 15. One end of the transmission shaft of the active transmission box 15 is provided with an active conical clamping head 16. The driven clamping assembly includes a telescopic mechanism housing 17. The telescopic mechanism housing 17 is provided with two guide rods 18 and a lead screw 19 located between the two guide rods 18. A main telescopic rod 20 that slides with the guide rods 18 is threaded onto the lead screw 19. The end of the main telescopic rod 20 is provided with a first mounting cavity 21 and a second mounting cavity 22. A locking push rod 23 is slidably provided between the first mounting cavity 21 and the second mounting cavity 22. The end of the locking push rod 23 is provided with a driven conical clamping head corresponding to the active conical clamping head 16. 24. A buffer spring 25 is connected between the driven conical clamping head 24 and the first mounting cavity 21. A locking position switch 26 is provided in the second mounting cavity 22. An active motor 28 is provided at the end of the piston rod of the first cylinder 27. A first coupling 29 corresponding to the output shaft of the active transmission box 15 is provided at one end of the transmission shaft. A propulsion motor 31 is provided at the end of the piston rod of the second cylinder 30. A second coupling 32 corresponding to the output shaft of the propulsion motor 31 is provided at the end of the lead screw 19 away from the active conical clamping head 16. The mesh frame rods are sequentially placed into the loading chamber 2. The inner cavity size of the loading chamber 2 is adapted to the mesh frame rods. The mesh frame rods fall into the U-shaped seat 34 at the upper end of the piston rod of the lifting cylinder 33. At this time, the second cylinder 33 is activated. Cylinder 30, the second cylinder 30 drives the propulsion motor 31 to move. The output shaft of the propulsion motor 31, in conjunction with the second coupling 32, drives the lead screw 19 to rotate. The rotation of the lead screw 19 drives the main telescopic rod 20 to move forward. The main telescopic rod 20 drives the driven conical clamping head 24 to move closer to the space frame rod and, in conjunction with the active conical clamping head 16, clamps and fixes the space frame rod. When the driven conical clamping head 24 approaches the space frame rod, the buffer spring 25 acts as a buffer. At this time, the end of the locking push rod 23 away from the driven conical clamping head 24 contacts the locking position switch 26, and the propulsion motor 31 stops rotating, thus locking the space frame rod. The transmission motor is started to drive the transmission of the active wheel and the driven wheel. The active wheel and the driven wheel drive the transmission on both sides. The conveyor belt 14 transmits the poles, thereby sequentially conveying several active clamping components 9 and driven clamping components 10. When the poles are conveyed into the spraying box 3, multiple first cylinders 27 drive the active motor 28 to move. The output shaft of the active motor 28, in conjunction with the first coupling 29, drives the conveying of the poles, thus achieving step-by-step, efficient, and comprehensive spraying of the poles. After spraying, the poles enter the drying zone for drying and then reach the end of the pole conveying mechanism. At this time, the second cylinder 30 at the end is activated to drive the propulsion motor 31 to move. The output shaft of the propulsion motor 31, in conjunction with the second coupling 32, drives the lead screw 19 to rotate in the opposite direction. The reverse rotation of the lead screw 19 drives the main telescopic rod 20 to move backward, thereby releasing the clamping of the poles.

[0035] In this embodiment, the main support frame 2 is provided with a support column 56 that passes through the secondary support frame 54 and is slidably engaged with the secondary support frame 54. The support column 56 is provided with a lifting cylinder 33. The upper end of the piston rod of the lifting cylinder 33 is provided with a U-shaped seat 34. The lifting cylinder 33 pushes the U-shaped seat 34 to facilitate material receiving. The slidable engagement between the support column 56 and the secondary support frame 54 facilitates the adjustment of the lateral position of the secondary support frame 54.

[0036] In this embodiment, the spraying assembly includes two longitudinal beams 35 arranged opposite each other within the spraying box 3, with a crossbeam 36 connecting the two longitudinal beams 35. A guide rail 37 is provided at the front end of the crossbeam 36, and a movable seat 38 is slidably mounted on the guide rail 37. A motor mounting plate 39 is provided at the upper end of the movable seat 38, and a reciprocating motor 40 is provided on the motor mounting plate 39. A drive gear is provided at the bottom end of the output shaft of the reciprocating motor 40. A transmission rack 41 that meshes with the drive gear is provided at the upper end of the crossbeam 36. A spray gun 42 is mounted at the front end of the movable seat 38. When the reciprocating motor 40 is started, it drives the drive gear to rotate. The forward and reverse rotation of the drive gear, in conjunction with the transmission rack 41, drives the spray gun 42 to reciprocate, thereby enabling comprehensive spraying of the grid pole.

[0037] In this embodiment, the upper end of the spray box 3 is provided with a paint storage tank 43 and a paint pump 44 located on one side of the paint storage tank 43. The paint pump 44 has a paint pumping end connected to the paint storage tank 43 and a paint outlet end provided with a paint guiding hose 45 connected to the spray gun 42.

[0038] In this embodiment, the drying mechanism includes an upper drying box 46 and a lower drying box 47 mounted on a second mounting frame. The lower drying box 47 passes through a support frame 54 and is slidably connected to the support frame 54. A high-speed fan 48 is provided above the upper drying box 46. The air outlet of the high-speed fan 48 is provided with a circulation pipe 49 that communicates with the lower drying box 47. An air filter 50 and a heating box 51 are provided on the circulation pipe 49.

[0039] In this embodiment, in order to adjust the distance between the active clamping mechanism 9 and the driven clamping mechanism 10 over a wide range so as to clamp and spray the grid rods of different lengths, a transverse guide rail 52 is provided on the base plate 1. The support frame 54 is slidably connected to the transverse guide rail 52 through a slide block at the bottom. A transverse pushing cylinder 53 is also provided on the base plate 1, and the end of the piston rod of the transverse pushing cylinder 53 is fixedly connected to the side of the support frame 54. Activating the transverse pushing cylinder 53 will drive the driven clamping mechanism 10 and the corresponding components to move laterally.

[0040] In a specific implementation of this invention, the mesh frame rods are sequentially placed into the loading chamber 2. During the implementation process, a heating device is added to the bottom plate of the loading chamber 2 to maintain a certain temperature for the mesh frame rods awaiting spraying, thereby increasing the adhesion of the spray coating. The inner cavity size of the loading chamber 2 is adapted to the mesh frame rods. The mesh frame rods fall into the U-shaped seat 34 at the upper end of the piston rod of the lifting cylinder 33. At this time, the second cylinder 30 is activated, which drives the propulsion motor 31 to move. The output shaft of the propulsion motor 31, in conjunction with the second coupling 32, drives the lead screw 19 to rotate. The rotation of the lead screw 19 drives the main telescopic rod 20 to move forward. The main telescopic rod 20 drives the driven conical clamping head 24 to move closer to the mesh frame rod and, in conjunction with the active conical clamping head 16, clamps and fixes the mesh frame rod. When the driven conical clamping head 24 approaches the mesh frame rod, the buffer spring 25 acts as a buffer. At this time, the end of the locking push rod 23 away from the driven conical clamping head 24 contacts the locking position switch 26. The propulsion motor 31 stops rotating, thus locking the space frame pole. The transmission motor is started, driving the drive wheel and driven wheel. The drive wheel and driven wheel drive the two side conveyor belts 14 to transmit, thus causing several active clamping components 9 and driven clamping components 10 to be transmitted in sequence. When the space frame pole is transmitted into the spray box 3, multiple first cylinders 27 drive the drive motor 28 to move. The output shaft of the drive motor 28, in conjunction with the first coupling 29, drives the transmission of the space frame pole, thereby realizing the step-by-step efficient and comprehensive spraying of the space frame pole. After spraying, the space frame pole enters the drying area for drying and then reaches the end of the space frame pole transmission mechanism. At this time, the second cylinder 30 at the end is started, driving the propulsion motor 31 to move. The output shaft of the propulsion motor 31, in conjunction with the second coupling 32, drives the lead screw 19 to rotate in the opposite direction. The reverse rotation of the lead screw 19 drives the main telescopic rod 20 to move backward, thereby releasing the clamping of the space frame pole. The space frame pole slides down under the action of gravity, thus completing the unloading.

[0041] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
