Description

Technical Field

[0001] This utility model relates to the field of sandblasting equipment technology, specifically to a dual-gun linkage sandblasting equipment. Background Technology

[0002] The steel shot blasted by the sandblasting equipment impacts and cuts the surface of the workpiece, giving the workpiece a certain degree of cleanliness and different roughness, thus improving the mechanical properties of the workpiece surface, enhancing its fatigue resistance, increasing the adhesion between the workpiece and the coating, and extending the durability of the coating film. Traditional grinding involves the worker holding a spray gun, which is connected to a sand storage tank and an air compressor. The air compressor is controlled to make the spray gun grind the surface of the workpiece. However, only one spray gun can be operated at a time, and it is easy to cause uneven grinding of the workpiece surface. This results in low work efficiency and affects the mechanical properties of the workpiece. Utility Model Content

[0003] The purpose of this utility model is to provide a reasonably designed and easy-to-use dual-gun linkage sandblasting device that addresses the defects and shortcomings of the existing technology, and can effectively solve the defects of the existing technology.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: it includes a sandblasting box, a first spray gun, and a connecting pipe. A first spray gun is installed on one side of the top of the sandblasting box. The first spray gun is connected to the connecting pipe via a flexible hose. The connecting pipe is fixed to the outer top wall of the sandblasting box and connected to a sand storage tank via an air compressor. It also includes:

[0005] The fixing plates are two in number and are symmetrically arranged in the sandblasting box. The two sides of the fixing plates penetrate the two side walls of the sandblasting box and are exposed on the outside of the sandblasting box.

[0006] The conveying rollers consist of several rollers, which are symmetrically connected to a fixed plate in pairs via bearings. The lower side of the fixed plate is connected to a drive rod via bearings. The drive rod is connected to the shaft on several adjacent conveying rollers via a worm gear pair. One end of each drive rod is connected to a drive motor.

[0007] The flipping mechanism consists of several units, which are equidistantly arranged inside the sandblasting box and positioned between the conveyor rollers.

[0008] There are several No. 2 spray guns, which are arranged one-to-one in front of No. 1 spray gun. The No. 2 spray gun is connected to the corresponding connecting pipe through a hose. A partition is set between two adjacent No. 2 spray guns, and the partition is fixedly connected to the top wall of the sandblasting box.

[0009] Connecting shafts, there are several connecting shafts, and they are connected one-to-one through and fixed to the No. 1 spray gun and the No. 2 spray gun. The connecting shafts are screwed to the partition and the inner wall of one side of the sandblasting box by bearings.

[0010] The rotating rod consists of several rotating rods, each corresponding to one side of the No. 1 spray gun. The front and rear ends of the rotating rod are screwed onto the sandblasting box via bearings. The rotating rod is connected to the connecting shafts on the front and rear sides via worm gear pairs. The threads of the two worm gear pairs on the same rotating rod are arranged in opposite directions.

[0011] The above technical solution involves placing the workpiece on the conveyor rollers, starting the drive motor, which in turn drives the drive rod to rotate. The drive rod, through a worm gear pair, drives the corresponding conveyor rollers to rotate, which in turn moves the workpiece. When the workpiece moves to the side below the first and second spray guns, the first and second spray guns are activated, allowing sandblasting to be performed during the movement. Furthermore, the workpiece can be flipped using a tilting mechanism during this process, facilitating sandblasting and polishing of different surfaces and improving work efficiency. During polishing, the rotating rod can be rotated as needed, driving the corresponding connecting shaft to rotate through the worm gear pair. Because the threads of the two worm gear pairs on the same rotating rod are opposite, the nozzles of the symmetrically positioned first and second spray guns rotate to a suitable angle.

[0012] As a further improvement of this utility model, a rotating disk is fixed on the front end of the rotating rod, and the rotating disk is embedded in a circular groove on the front side wall of the sandblasting box; this facilitates the rotation of the rotating rod.

[0013] As a further improvement of this utility model, sliding blocks are fixed on both the left and right sides of the lower surface of the fixed plate. The sliding blocks are slidably arranged in the sliding grooves on the lower inner walls of both sides of the sandblasting box. A double-acting screw is screwed to the lower inner side of both sides of the sandblasting box through bearings. The front and rear ends of the double-acting screw are respectively screwed to the adjacent sliding blocks through threads. The two double-acting screws are connected by a synchronous wheel transmission assembly. An adjusting motor is fixed to the front end of one of the double-acting screws.

[0014] According to the above technical solution, the adjustment motor is started according to the size of the workpiece. The adjustment motor drives the bidirectional lead screw connected to it to rotate. The bidirectional lead screw drives another bidirectional lead screw to rotate through the synchronous wheel transmission assembly. The two bidirectional lead screws simultaneously drive the fixed plate to move through the sliding blocks at both ends until the fixed plate drives the conveyor roller to move to the appropriate position.

[0015] As a further improvement of this utility model, the flipping mechanism includes:

[0016] The flipping frame is installed inside the sandblasting box. The flipping frame is arranged in a "+" shape. A flipping rod is inserted through and fixed in the center of the flipping frame. The front and rear ends of the flipping rod are respectively screwed to the front and rear inner walls of the sandblasting box through bearings.

[0017] The reset switches are four in number and are fixed one-to-one on the four support plates of the flipping frame. A flipping motor is embedded in the front side wall of the sandblasting box and is connected to the four reset switches.

[0018] With the above technical solution, when the conveying rollers convey the workpiece, when the workpiece comes into contact with the reset switch on the flipping frame, the flipping motor is started by the reset switch. The flipping motor drives the flipping rod to rotate, the flipping rod drives the flipping frame to rotate, and after the flipping frame drives the workpiece to rotate 90°, the support plate of the flipping frame located on the lower side of the workpiece separates from the workpiece, thereby resetting the reset switch and stopping the flipping motor from rotating.

[0019] As a further improvement of this utility model, the outer side of the conveying roller is fitted with an anti-slip ring, and the two side walls of the anti-slip ring are set in the same plane as the two sides of the conveying roller.

[0020] The above technical solution can increase the friction between the transmission roller and the workpiece.

[0021] As a further improvement of this utility model, a guide hopper is provided on the lower side of the inside of the sandblasting box. The lower end of the guide hopper is inserted into the bottom wall of the sandblasting box. A conveyor box is embedded and fixed on the outer bottom wall of the sandblasting box. The lower end of the guide hopper is connected to the conveyor box. A spiral conveying rod is provided inside the conveyor box. The spiral conveying rod is screwed onto the conveyor box by a motor.

[0022] Through the above technical solution, the sand and impurities from sandblasting fall into the guide hopper, then enter the conveying box through the guide hopper, and finally are discharged by the conveying of the screw conveyor.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows: The dual-gun linkage sandblasting equipment described in this utility model can perform sandblasting and grinding operations simultaneously through two symmetrical spray guns, and the two spray guns are in a linkage state, which facilitates operation and improves the sandblasting and grinding effect. This utility model has the advantages of reasonable setting and low manufacturing cost. Attached Figure Description

The right end of each drive rod 6 is connected to a drive motor 7. The outer side of each conveying roller 5 is fitted with an anti-slip ring 17. The two side walls of the anti-slip ring 17 are set in the same plane as the two sides of the conveying roller 5, which can increase the friction between the conveying roller 5 and the workpiece.

[0034] The flipping mechanism 8 consists of several units, which are equidistantly arranged inside the sandblasting box 1 and are positioned between the conveying rollers 5.

[0035] There are several No. 2 spray guns 9, and they are arranged one-to-one in front of No. 1 spray gun 2. The No. 2 spray gun 9 is connected to the corresponding connecting pipe 3 through a hose. A partition 10 is provided between two adjacent No. 2 spray guns 9. The partition 10 is welded and fixed to the top wall of the sandblasting box 1.

[0036] A connecting shaft 11 is provided, and there are several connecting shafts 11, which are connected and fixed to the No. 1 spray gun 2 and the No. 2 spray gun 9 respectively. The connecting shaft 11 is screwed to the partition plate 10 and the inner wall of one side of the sandblasting box 1 through bearings. A guide hopper 18 is provided on the lower side of the inside of the sandblasting box 1. The lower end of the guide hopper 18 is inserted into the bottom wall of the sandblasting box 1. A conveyor box 19 is embedded and fixed on the outer bottom wall of the sandblasting box 1. The lower end of the guide hopper 18 is connected to the conveyor box 19. A spiral conveyor rod 20 is provided inside the conveyor box 19. The spiral conveyor rod 20 is screwed to the conveyor box 19 through a motor. The sand and impurities from sandblasting fall into the guide hopper 18, then enter the conveyor box 19 through the guide hopper 18, and finally are discharged through the conveyor rod 20.

[0037] There are several rotating rods 12, each corresponding to one side of the No. 1 spray gun 2. The front and rear ends of the rotating rods 12 are screwed onto the sandblasting box 1 through bearings. The rotating rods 12 are connected to the connecting shafts 11 on the front and rear sides through worm gear pairs. The threads of the two worm gear pairs on the same rotating rod 12 are arranged in opposite directions. A rotating disk 13 is welded and fixed to the front end of the rotating rod 12. The rotating disk 13 is embedded in a circular groove on the front side wall of the sandblasting box 1, which facilitates the rotation of the rotating rods 12. Example 2

[0038] See Figure 1-2 , Figure 4 As shown, based on Embodiment 1, the flipping mechanism 8 includes:

[0039] The flipping frame 8-1 is installed inside the sandblasting box 1. The flipping frame 8-1 is arranged in a "+" shape. A flipping rod 8-2 is welded through and fixed in the center of the flipping frame 8-1. The front and rear ends of the flipping rod 8-2 are respectively screwed to the front and rear inner walls of the sandblasting box 1 through bearings.

[0040] There are four reset switches 8-3, and they are fixed one-to-one with the four support plates of the flipping frame 8-1 by bolts. The front side wall of the sandblasting box 1 is embedded with a flipping motor 8-4, which is connected to the four reset switches 8-3.

[0041] When using this invention, depending on the size of the workpiece, start the adjusting motor 16. The adjusting motor 16 drives the connected bidirectional lead screw 15 to rotate. This bidirectional lead screw 15 drives another bidirectional lead screw 15 to rotate through the synchronous pulley transmission assembly. The two bidirectional lead screws 15 simultaneously drive the fixed plate 4 to move through the sliding blocks 14 at both ends until the fixed plate 4 drives the conveyor roller 5 to move to the appropriate position. Place the workpiece on the conveyor roller 5, start the drive motor 7. The drive motor 7 drives the drive rod 6 to rotate. The drive rod 6 drives the corresponding conveyor roller 5 to rotate through the worm gear pair. The conveyor roller 5 moves the workpiece. When the workpiece moves to the lower side of the first spray gun 2 and the second spray gun 9, start the first spray gun 2 and the second spray gun 9. Sandblasting can be performed during the movement. The conveyor roller 5 conveys the workpiece. When the workpiece comes into contact with the reset switch 8-3 on the flipping frame 8-1, the flipping motor 8-4 is activated by the reset switch 8-3. The flipping motor 8-4 drives the flipping rod 8-2 to rotate, and the flipping rod 8-2 drives the flipping frame 8-1 to rotate. After the flipping frame 8-1 rotates the workpiece 90°, the support plate on the underside of the workpiece on the flipping frame 8-1 separates from the workpiece, thereby resetting the reset switch 8-3 and stopping the flipping motor 8-4. This facilitates sandblasting and polishing different surfaces, improving work efficiency. During polishing, the rotating rod 12 can be rotated according to the requirements. The rotating rod 12 drives the corresponding connecting shaft 11 to rotate through the worm gear pair. Since the threads of the two worm gear pairs on the same rotating rod 12 are opposite, the nozzles of the first spray gun 2 and the second spray gun 9, which are symmetrically positioned, rotate to the appropriate angle.

[0042] Compared with the prior art, the beneficial effects of this specific embodiment are as follows:

[0043] 1. Sandblasting and polishing operations are performed simultaneously by spray gun 2 and spray gun 9, which are symmetrically arranged and linked together, thus facilitating operation and improving the sandblasting and polishing effect.

[0044] 2. During the conveying process, the workpiece is conveyed by the conveying roller 5. The position of the fixed plate 4 and the conveying roller 5 can be adjusted by the size of the workpiece through the sliding block 14, the bidirectional lead screw 15 and the adjusting motor 16 to meet the usage requirements.

[0045] 3. Several flipping mechanisms 8 are provided between the front and rear conveying rollers 5. During the movement of the workpiece, the workpiece can be flipped by several flipping mechanisms 8, which makes it convenient to grind different sides of the workpiece.

[0046] 4. A guide hopper 18 and a conveyor box 19 are provided on the lower side of the sandblasting box 1 to facilitate the collection of sand and impurities, which are then conveyed by the screw conveyor 20 for easy discharge.

[0047] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features.
