Description

Technical Field

[0001] This utility model relates to the field of spraying technology, and in particular to an automatic spraying device for tubular metal castings. Background Technology

[0002] Spraying refers to a processing method in which paint is atomized by a spray gun and applied to the surface of an object. After tubular metal castings are completed, a coating such as an anti-rust coating needs to be sprayed onto the surface.

[0003] A search revealed Chinese patent CN221086073U, which discloses a spraying device for processing tubular products. Although the aforementioned patent allows for the installation and disassembly of the bracket through an installation structure, increasing its applicability, the tube is placed directly on the bracket, and only one side can be sprayed. The other side is obstructed and cannot be sprayed at the same time, resulting in low practicality. In order to better address the above problems and promote the improvement of industry standards, this application proposes a new spraying device that is different from the prior art. Utility Model Content

[0004] The purpose of this invention is to solve the problem of uneven coating in existing coating systems by proposing an automatic coating device for tubular metal castings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic spraying device for tubular metal castings includes a processing box and a spraying mechanism. A protective door is rotatably connected to one side of the processing box. Rotating tubes are provided on both sides of the processing box. One end of each rotating tube is threaded with a lead screw. One end of the lead screw is rotatably connected to a conical block. The outer wall of the conical block is provided with multiple dovetail grooves. A sliding block is slidably connected in the dovetail groove. A connecting rod is fixedly connected to one side of the sliding block. A top block is fixedly connected to the other end of the connecting rod. The circumference of the rotating tube is provided with multiple rectangular grooves. The connecting rod passes through the rectangular grooves.

[0007] Furthermore, a motor is fixedly connected to one side of the outer wall of the processing box, a reciprocating lead screw is fixedly connected to the output end of the motor, a second gear is fixedly connected to one end of the reciprocating lead screw, a first gear is fixedly connected to one end of one of the rotating tubes, a chain is connected between the first gear and the second gear, a slider is threadedly connected to the outer wall of the reciprocating lead screw, and the spraying mechanism is located at the bottom of the slider.

[0008] Furthermore, a sliding rod is fixedly connected between the inner walls of both sides of the processing box, and the slider is slidably sleeved with the sliding rod.

[0009] Furthermore, the spraying mechanism includes multiple nozzles, a mounting plate is fixedly connected to the bottom of the slider, multiple detachable nozzles are inserted into the inner side of the mounting plate, a diverter tube is provided on the slider, a spring hose is sleeved on one end of the diverter tube, multiple connecting tubes are sealed and inserted on one side of the diverter tube, and the other end of the connecting tube is inserted into the nozzle.

[0010] Furthermore, a locking nut is threaded to one end of the lead screw, and an adjusting handle is fixedly connected to this end of the lead screw.

[0011] Furthermore, a handle is fixedly connected to one side of the outer wall of the protective door, and the outer wall of the handle is provided with an anti-slip groove.

[0012] Furthermore, a sliding groove is provided on one side of the protective door, and a mounting bracket is slidably connected between the two sliding grooves. A sponge block is fixedly connected to one side of the mounting bracket, and the sponge block rubs against the inside of the observation window.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By driving the rotating tube to rotate under the transmission action of the chain, the tubular metal casting is rotated, thereby adjusting the spraying surface of the tubular metal casting to achieve full coating and improve the coating quality of the tubular metal casting.

[0015] 2. By turning the adjusting handle, the lead screw is rotated, which in turn moves the conical block. Under the pressure of the conical block, the sliding block moves within the dovetail groove, causing the connecting rod and the top block to move outward. This tensions the tubular metal casting from within, thus securing the tubular metal casting quickly and easily.

[0016] 3. The paint is fed into the spring hose by the pump, and then into the nozzle through the distributor and connecting pipe. The paint is then sprayed from the nozzle onto the tubular metal casting. At the same time, the reciprocating screw rotates under the drive of the motor, which causes the slider to move along the slide bar, thereby driving the nozzle to move back and forth. This sprays the tubular metal casting back and forth, saving time and effort. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 1-7 An automatic spraying device for tubular metal castings includes a processing box 1 and a spraying mechanism, wherein a protective door 2 is rotatably connected to one side of the processing box 1.

[0027] A motor 3 is bolted to one side of the outer wall of the processing box 1. A reciprocating screw 4 is bolted to the output end of the motor 3. A second gear 1201 is keyed to one end of the reciprocating screw 4. A slider 6 is threaded to the outer wall of the reciprocating screw 4. The spraying mechanism is located at the bottom of the slider 6. A slide rod 5 is detachably fixed between the inner walls of the two sides of the processing box 1. The slider 6 is slidably sleeved with the slide rod 5. Driven by the motor 3, the reciprocating screw 4 rotates, thereby causing the slider 6 to move along the slide rod 5, which in turn drives the spraying mechanism to move back and forth, thus spraying the tubular metal casting back and forth.

[0028] The spraying mechanism includes multiple nozzles 801. The bottom of the slider 6 is fixed with a mounting plate 7 by bolts. Multiple detachable nozzles 801 are inserted into the inner side of the mounting plate 7. A diversion pipe 9 is passed through the slider 6. One end of the diversion pipe 9 is fitted with a spring hose 10. Multiple connecting pipes 8 are sealed and inserted into one side of the diversion pipe 9. The other end of the connecting pipe 8 is inserted into the nozzle 801. Under the action of the pump, the paint from the outside is input into the spring hose 10, and then input into the nozzle 801 through the diversion pipe 9 and the connecting pipe 8. Then, the paint is sprayed from the nozzle 801 onto the tubular metal casting.

[0029] It should be noted that the top of the processing box 1 has a strip groove to facilitate the movement of the spring hose 10, and a corrugated shield is provided on the strip groove, through which the spring hose 10 passes.

[0030] On the same side of the motor 3, a rotating tube 11 is rotatably mounted on the processing box 1 via an embedded bearing. On the opposite side of the motor 3, a circular through hole is opened on the processing box 1. Multiple bullseye balls 21 are fixedly installed in the through hole by bolts. Another rotating tube 11 is inserted between the multiple bullseye balls 21. The rotating tube 11 can rotate and be pulled between the multiple bullseye balls 21. A limit ring is also sleeved on the rotating tube 11 to prevent it from being completely pulled out.

[0031] Two rotating tubes 11 are threaded to both ends with lead screws 13. One end of the lead screw 13 is welded with an adjusting handle 20, and the other end of the lead screw 13 is rotatably connected to a conical block 14. The outer wall of the conical block 14 is provided with multiple dovetail grooves 15. A sliding block 16 is slidably connected in the dovetail grooves 15. A connecting rod 17 is welded to one side of the sliding block 16, and a top block 18 is welded to the other end of the connecting rod 17. The circumference of the rotating tube 11 is provided with multiple rectangular grooves 19. The connecting rod 17 passes through the rectangular grooves 19, and the tubular metal casting is fitted onto the rotating tube 11. Turning the adjusting handle 20 drives the lead screw 13 to rotate, thereby driving the conical block 14 to move. Under the compression of the conical block 14, the sliding block 16 moves in the dovetail grooves 15, thereby causing the connecting rod 17 and the top block 18 to move outward, and thus tensioning from the inside of the tubular metal casting, thereby fixing the tubular metal casting.

[0032] In addition, a locking nut is threaded to one end of the lead screw 13. Tightening the locking nut makes it fit against the end face of the rotating tube 11, thereby fixing the lead screw 13 and preventing it from loosening.

[0033] One end of the rotating tube 11 on the same side of the motor 3 is keyed to a first gear 12. A chain 1202 is connected between the first gear 12 and the second gear 1201. Under the transmission action of the chain 1202, the rotating tube 11 is driven to rotate, thereby driving the tubular metal casting to rotate, and thus adjusting the spraying surface of the tubular metal casting so as to spray the tubular metal casting comprehensively.

[0034] A handle 201 is bolted to one outer wall of the protective door 2. The outer wall of the handle 201 is provided with an anti-slip groove, which facilitates the opening and closing of the protective door 2. A sliding groove 203 is provided on one side of the protective door 2. A mounting bracket 204 is slidably connected between the two sliding grooves 203. A sponge block 205 is glued to one side of the mounting bracket 204. The sponge block 205 rubs against the inside of the observation window 202. Pulling the mounting bracket 204 moves the sponge block 205, which rubs against the inside of the observation window 202, thereby wiping away the paint adhering to the inside of the observation window 202. A collection tray for collecting paint is provided inside the processing box 1.

[0035] The working principle of this embodiment is as follows: When in use, first connect one end of the spring hose 10 to the outlet end of the pump body, and connect the inlet end of the pump body to the paint storage tank. First, pull the handle 201 to open the protective door 2. Then, first pull the pullable rotating tube 11 outward to place the tubular metal casting between the two rotating tubes 11, and then push it back. Next, turn the adjusting handle 20 to drive the screw 13 to rotate, thereby driving the conical block 14 to move. Then, under the compression of the conical block 14, the sliding block 16 moves in the dovetail groove 15, thereby causing the connecting rod 17 and the top block 18 to move outward, thereby tightening from the inside of the tubular metal casting, thereby fixing the tubular metal casting. Then, tighten the locking nuts on the screw 13 to prevent the top block 18 from loosening, thereby ensuring that the tubular metal casting will not shift during rotation. Finally, close the protective door 2.

[0036] Next, the pump body is started, and under the action of the pump body, the paint is input into the spring hose 10, and then into the nozzle 801 through the diverter pipe 9 and the connecting pipe 8. Then, the paint is sprayed from the nozzle 801 onto the tubular metal casting. At the same time, the motor 3 is started, and under the drive of the motor 3, the reciprocating screw 4 rotates, thereby causing the slider 6 to move along the slide bar 5, which in turn drives the nozzle 801 to move back and forth, thus spraying the tubular metal casting back and forth. Meanwhile, under the transmission action of the chain 1202, the rotating tube 11 is driven to rotate, thereby driving the tubular metal casting to rotate, thereby adjusting the spraying surface of the tubular metal casting so as to carry out a full painting operation on the tubular metal casting.

[0037] During the painting process, the mounting bracket 204 is pulled to move the sponge block 205, which causes the sponge block 205 to rub against the inside of the observation window 202, thereby wiping away the paint adhering to the inside of the observation window 202. This allows the painting status of the tubular metal casting to be observed through the observation window 202. Excess paint drips onto the collection tray inside the processing box 1 and is eventually disposed of.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
