Description

Technical Field

[0001] The invention belongs to the technical field of valve fittings processing, and in particular relates to a valve bracket surface pretreatment device and method. Background Art

[0002] The valve bracket is a device used to support the valve, usually installed on both sides of the valve to ensure the stability and operability of the valve. The selection of the valve bracket should meet the design requirements and be able to withstand the weight and working pressure of the valve. Its material should match the material of the pipe and valve to ensure the strength and stability of the bracket.

[0003] Surface pretreatment of valve brackets is an important step in the valve manufacturing process. It can improve the corrosion resistance, wear resistance and aesthetics of valve brackets, thereby extending the service life of the valve.

[0004] After searching Chinese patents, the utility model patent with patent number CN218132763U discloses a panel bracket surface treatment device, including a shell, a mounting frame is installed at the bottom end of the shell, and support frames are installed at both ends of the top of the mounting frame. A rotating shaft is provided on both sides of the top of the support frame, and the rotating shaft is fixed on the support frame through a bearing. A tray is installed on the top of the rotating shaft. A receiving cavity is opened at the bottom of the shell, and the bottom of the rotating shaft is placed in the receiving cavity. A first sprocket is installed at the bottom of the rotating shaft, and a connecting shaft is provided in the middle of the receiving cavity. Both ends of the connecting shaft are fixed in the receiving cavity through bearings. A second sprocket is provided in the middle of the connecting shaft. The first sprocket and the second sprocket are connected by a chain. A motor is installed at the bottom of the connecting shaft, and the motor is fixed to the bottom of the shell through a motor bracket. A spraying mechanism is provided on the top of the shell. This application can control the rotation of the tray through the rotating shaft, so that the workpiece can be controlled to rotate during spraying, so that the spraying is uniform and the surface treatment quality is improved. However, it still has the following disadvantages in actual use: In order to support and install valves, the support plate of the valve bracket will be set to an arc surface. During the processing of the inner arc surface, direct rotation and other treatments will cause uneven painting on the inner arc surface, and there will be certain burrs on the inner arc surface, which requires grinding. During the grinding operation, the operator is required to directly operate the grinding head of the grinder or other equipment to enter the inner arc surface of the support plate for grinding. After grinding, the debris on the inner arc surface needs to be blown away manually, which is more troublesome. Summary of the invention

The polishing of the arc-shaped polished surface on the support plate is more convenient. As the belt conveyor drives the movement of the belt, the mounting seat is driven to move, and the polished surface on the support plate is driven to pass under the air blowing shell. When the air blowing shell is working, high-pressure air is transported from the high-pressure pipeline connector connected to the joint to the connecting pipe, and then transported to the air blowing shell through the connecting pipe. High-pressure air is blown onto the polished surface through the exhaust port on the air blowing shell for cleaning, and the cleaning is convenient. After the paint to be sprayed is transported to the paint spray shell, the airflow and the flow direction of the paint are opposite, and the airflow hits the paint, causing the paint to scatter. After being completely atomized, the paint is discharged through the paint spray port to the polished surface of the support plate passing under the paint spray shell, completing the painting of the polished surface of the support plate. The paint spray port is arranged in an arc shape, so that the inner arc surface on the bracket can be evenly sprayed with paint, and the paint spraying is more uniform.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figure 1 , 2, 3, 9, the present invention is a valve bracket surface pretreatment device, including a belt conveyor 1 and a support plate 7. During operation, a reducer 102 is fixed at one side edge of the belt conveyor 1, and the power output end of the reducer 102 is fixed to the belt conveyor 1, and a driving motor 103 is also fixed on the reducer 102, and the power output end of the driving motor 103 is fixed to the power input end of the reducer 102, so that when the driving motor 103 is working, the reducer 102 is driven to start working, and the torque generated by the driving motor 103 is changed by the reducer 102, and the power is output to the belt conveyor 1, and at the same time, a movable plate 101 is fixed on the two long sides of the top of the belt conveyor 1, and the bottom of the movable plate 101 is rotatably connected to the matching roller 1011 arranged above the belt of the belt conveyor 1.

[0022] Specifically, mounting strips 702 are fixed on the two straight edges of the outer arc surface of the support plate 7. After the processing is completed, the valve is installed in cooperation with other external valve installation structures. At the same time, the mounting seat 704 at the bottom end of the pillar 703 fixed on the outer arc surface of the support plate 7 is installed in cooperation with the supporting plane for valve installation, and is supported on the belt conveyor 1 during processing. The driving motor 103 drives the reducer 102 to work. When the reducer 102 works, the output power drives the belt conveyor 1 to work. During the operation of the belt conveyor 1, the belt of the belt conveyor 1 moves, driving the mounting seat 704 to move. The movement of the mounting seat 704 drives the support plate 7 to move, so that the polished surface 701 of the support plate 7 passes under the flexible sponge sleeve 3, the blowing shell 5 and the paint spraying shell 6 in turn. When the mounting seat 704 is set on the belt of the belt conveyor 1, the top of the mounting seat 704 contacts each other with the roller, and the roller abuts against the mounting seat 704 during the movement of the mounting seat 704, thereby maintaining the stability of the mounting seat 704 in conveying on the belt conveyor 1.

[0023] Furthermore, when the belt conveyor 1 is working, the belt at its conveying position moves from the fixed plate 2 to the support rod 4. After the mounting seat 704 at the bottom end of the support 703 is placed on the belt of the belt conveyor 1, the mounting seat 704 is driven by the belt to pass under the movable plate 101. The distance between the lower part of the peripheral side of the matching roller 1011 and the belt conveying surface is equal to the thickness of the mounting seat 704. When the matching roller 1011 on the movable plate 101 is pressed onto the top of the mounting seat 704, the matching rollers 1011 on the two movable plates 101 are pressed together on the mounting seat 704 to ensure that the mounting seat 704 will not tip over or other processing accidents during operation, thereby increasing the stability of the mounting seat 704 during processing.

[0024] Example 2: Please refer to Figure 1 , 4, 5, 9, on the basis of the specific embodiment 1, it also includes a fixed plate 2 and a flexible sponge sleeve 3, the side plates 209 fixed on both sides of the fixed plate 2 are used to connect with the telescopic end of the electric push rod 207, when the electric push rod 207 is working, the side plates 209 are driven to rise and fall, and the fixed plate 2 is driven to rise and fall, the connecting seats 208 on the two electric push rods 207 are fixed on both sides of the belt conveyor 1, and the hanging plates 201 fixed at the two short sides of the bottom of the fixed plate 2, and then the hanging plates 201 drive the rotating shaft 202 to rise and fall during the lifting of the fixed plate 2, and the two hanging plates 201 rotatably connect the rotating shaft 202 thereto, so that the connecting tube 204 is set between the two hanging plates 201, and when working, the Velcro fur surface 301 on the inner wall of the flexible sponge sleeve 3 is attached to the Velcro hook surface 205 on the connecting tube 204, and the sandpaper 302 fixed on the side of the flexible sponge sleeve 3 is used to grind the grinding surface 701 of the support plate 7 when it rotates.

[0025] Specifically, before the pallet 7 transported by the belt conveyor 1 passes under the fixed plate 2, the electric push rod 207 drives the side plate 209 fixed at its output end to descend, and drives the connecting plate 203 to descend. Through the descent of the connecting plate 203, the fixed plate 2 is driven to descend, so that the sandpaper 302 on the surface of the flexible sponge cover 3 between the two hanging plates 201 enters the polished surface 701 of the pallet 7. When the flexible sponge cover 3 passes over the polished surface 701 on the pallet 7, the rotating motor 206 drives the rotating shaft 202 to rotate. Through the rotation of the rotating shaft 202, the connecting plate 203 and the connecting tube 204 are driven to rotate. At the same time, the surrounding sides of the connecting tube 204 are driven to fit each other through the Velcro hook surface 205 and the Velcro fur surface 301. The restricted flexible sponge cover 3 rotates, driving the sandpaper 302 to polish the polished surface 701 of the inner arc surface of the pallet 7.

[0026] Furthermore, during the operation, when the sandpaper 302 becomes ineffective after working for a certain period of time, the electric push rod 207 is started to drive the fixed plate 2 to rise to a suitable height, and the flexible sponge tube is torn off from the Velcro hook surface 205 on the side of the connecting tube 204, and then a new sponge sheet with Velcro fur surface 301 and sandpaper 302 fixed on both sides is selected, and the Velcro fur surface 301 on the sponge sheet is applied to the Velcro hook surface 205 on the connecting tube 204 to complete the replacement. When the sandpaper 302 is replaced and can continue to work, the rotating motor 206 is started to drive the rotating shaft 202 to rotate through the rotating motor 206. When 202 rotates, it drives the connecting tube 204 to rotate. When the connecting tube 204 rotates, it drives the flexible sponge tube to rotate, and at the same time, the electric push rod 207 drives the side plate 209 to descend until the flexible sponge sleeve 3 enters the polishing surface 701 on the support plate 7. During the rotation of the flexible sponge sleeve 3, the sandpaper 302 is driven to rotate, and the polishing surface 701 on the support plate 7 is polished. During the working process, the belt conveyor 1 is used to convey the polishing surface 701 of the support plate 7 in a flowing manner and passes under the fixed plate 2. During the working process, the polishing surface 701 of the support plate 7 can be polished in a flowing manner and efficiently.

[0027] Example 3: Please refer to Figure 1 , 6 , 7, 8, 9, based on the specific embodiment 1 and the specific embodiment 2, it also includes a support rod 4, an air blowing shell 5 and a paint spraying shell 6, the air blowing shell 5 is fixed to the support rod 4 through the fixing hole 1 501, the paint spraying shell 6 is fixed to the support rod 4 through the fixing hole 2 601, the two ends of the support plate are fixed with a cross piece 401, both ends of the cross piece 401 are fixed with an L-shaped bracket 402, and the L-shaped bracket 402 is fixed to the belt conveyor 1, so that the support rod 4 is supported above the belt conveyor 1, the air blowing shell 5 and the paint spraying shell 6 are arranged above the belt conveyor 1, and during operation, the connecting pipe 502 connected to the upper part of the circumference of the air blowing shell 5 is fixed The top joint 503 is connected to the output end of the pipeline for conveying high-pressure air from the outside, and the high-pressure air is conveyed to the blowing shell 5 through the connecting pipe 502, and arc-shaped exhaust ports 504 are evenly spaced at the lower part of the circumference of the blowing shell 5, so that when working, the arc-shaped exhaust ports 504 convey air to the polished surface 701 on the support plate 7, blow air on the polished surface 701, and blow away the polishing debris on the polished surface 701 on the support plate 7, and the conveying pipes 603 on both sides of the paint spraying shell 6 are fixedly connected to the pipelines for conveying high-pressure air and conveying paint respectively, and the paint spray generated in the paint spraying shell 6 is sprayed out through the paint spraying port 602 opened at the bottom.

[0028] Specifically, when in operation, the air blowing shell 5 is connected to the output end of the high-pressure air pipeline through the joint 503 connected to the connecting pipe 502 at the upper part of the peripheral side thereof, and the high-pressure air entering therein is discharged through the exhaust port 504 opened at the lower part of the peripheral side thereof. When the support plate 7 passes under the air blowing shell 5, the compressed air is transported to the connecting pipe 502 through the pipeline, transported to the air blowing shell 5 through the connecting pipe 502, and discharged to the polishing surface 701 on the support plate 7 through the exhaust port 504 at the peripheral side of the air blowing shell 5. The debris on the polished surface 701 of the pallet 7 is blown away. When the polished surface 701 of the pallet 7 is cleaned, it is transported to the bottom of the paint spraying shell 6 by the belt conveyor 1. The two conveying pipes 603 respectively transport paint and high-pressure air to the paint spraying shell 6, and atomized paint is formed in the paint spraying shell 6. It is then sprayed out through the paint spraying port 602 at the bottom of the paint spraying shell 6 to spray paint on the polished surface 701 of the pallet 7. After completion, the pallet 7 is transported to the next processing position under the conveyance of the belt conveyor 1.

[0029] Furthermore, during the work process, the pallet 7 is transported by the belt conveyor 1 to drive the pallet 7 to move. During the movement of the pallet 7, after being polished under the fixed plate 2, the pallet 7 is transported to the bottom of the blowing shell 5, and the air is transported to the blowing shell 5 through the connecting pipe 502. Through the exhaust port 504 on the side of the blowing shell 5, the air is transported to the polished surface 701 on the pallet 7 one by one, so that the polished debris on the polished surface 701 is fully blown away, and the cleanliness of the polished surface 701 is higher. When the pallet 7 passes under the paint spraying shell 6, the lower part of the side of the paint spraying shell 6 is arc-shaped, and the paint spraying port 602 is semicircular, which increases the sufficiency of the paint spraying and makes the paint spraying on the polished surface 701 of the pallet 7 more uniform.
