Description

Technical Field

[0001] This utility model belongs to the field of valve coating processing technology, specifically a valve coating spraying device. Background Technology

[0002] A valve is a device in a fluid system used to control the direction, pressure, and flow rate of a fluid. It is a device that allows the medium in piping and equipment to flow or stop and controls its flow rate.

[0003] Valve coating is key to improving valve performance and extending service life. By forming a protective layer on the valve surface, it can effectively resist harsh working conditions such as corrosion, wear, and high temperature. In the production and processing of some valves, it is necessary to use spraying equipment to coat the valve surface. When spraying the valve, it is necessary to support the valve. However, when the existing spraying equipment supports the valve, some components will come into contact with the outer surface of the valve, which will have a certain impact on the spraying of the outer surface of the valve.

[0004] Therefore, this utility model provides a valve processing coating spraying device. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A valve processing coating spraying device of this utility model includes a spraying frame; a pair of support frames are installed on the top of the spraying frame, one support frame is fixedly installed on the spraying frame, and the other support frame is movably installed on the spraying frame; a cylinder is rotatably connected to the middle of the support frame; a first gear is fixedly connected to the middle of the cylinder; a motor is fixedly connected to the side wall of the support frame; a second gear is fixedly connected to the output end of the motor; the second gear and the first gear are meshed; multiple elastic plates are fixedly connected to the inner side wall of the cylinder; a protrusion is fixedly connected to one end of the elastic plate extending outside the cylinder; an adjusting rod is threadedly connected to the middle of the cylinder; a top block is rotatably connected to one end of the adjusting rod facing the multiple elastic plates; Through the above structure, when spraying the valve, the support mechanism only contacts and supports the valve's interior, reducing obstruction of the valve's outer surface and minimizing the impact on the spraying of the valve's outer surface.

[0007] Preferably, a plurality of support rods are fixedly connected to the middle of the spraying frame; one support frame is slidably connected to the middle of the plurality of support rods; a mounting plate is fixedly connected to the side wall of the support frame; a connecting rod is slidably connected to the middle of the mounting plate; a toothed block is fixedly connected to the end of the connecting rod; a spring is installed in the middle of the connecting rod; and a plurality of locking teeth are fixedly connected to the side wall of the spraying frame. With the above structure, the external of one support frame can be easily adjusted, so that the device can be used for spraying valves of different lengths and sizes. At the same time, it makes it difficult for impurities flying during spraying to fall on the toothed block and locking teeth and solidify, thus preventing a decrease in the mutual limiting effect of the toothed block and locking teeth.

[0008] Preferably, a fixing ring is fixedly connected to the end of the cylinder; multiple slots are provided in the middle of the fixing ring; and a rod is slidably connected to the side wall of the support frame. With the above structure, the rotation of the cylinder can be restricted when the adjusting rod is rotated, reducing the force transmitted to the cylinder during the adjustment of the adjusting rod, so that the cylinder rotates synchronously. This allows the top block to move under force better and increases the friction between the protrusion and the inner wall of the valve, thereby improving the support and rotation effect of the valve.

[0009] Preferably, a metal ring is fixed to the side wall of the cylinder; the metal ring is made of magnetic material; a magnet is fixed to the end of the insertion rod; with the above structure, when the adjusting rod is rotated and adjusted, the insertion rod does not need to be continuously supported and is difficult to disengage from the slot, thus improving the ease of use of the device.

[0010] Preferably, a top ring is threadedly connected to the middle of the cylinder; a rubber gasket is fixed to the side wall of the top ring; with the above structure, when spraying the outer surface of the valve, the occurrence of paint entering the valve from the valve port is reduced, thus reducing the impact on the quality of the valve product.

[0011] Preferably, the inner sidewall of the spraying frame is fixedly connected to multiple elastic membrane sleeves; the other end of each elastic membrane sleeve is fixedly connected to the sidewall of the support frame installed in the middle of the support rod, and the multiple elastic membrane sleeves respectively surround the multiple support rods inside; through the above structure, the flying paint can be blocked, making it difficult for the paint to fall on the support rod, thereby reducing the impact of paint solidification on the sliding of the support frame.

[0012] Preferably, the side wall of the spraying frame is fixed with an isolation plate; the isolation plate is located above multiple clamping teeth; through the above structure, the occurrence of flying paint falling on the tooth blocks and clamping teeth can be further reduced, and the occurrence of paint solidification leading to a decrease in the limiting effect of the tooth blocks and clamping teeth can be further reduced.

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

[0014] 1. The valve processing coating spraying device of this utility model, through the arrangement of a support frame, a cylinder, a first gear, a motor, a second gear, an elastic plate, a protrusion, an adjusting rod, and a top block, allows the support mechanism to contact and support the valve only inside the valve during valve spraying, reducing obstruction to the valve's outer surface and minimizing the impact on the spraying of the valve's outer surface.

[0015] 2. The valve processing coating spraying device of this utility model, through the arrangement of a bearing rod, mounting plate, connecting rod, toothed block, spring, and locking tooth, allows for convenient adjustment of the external bearing frame, making the device suitable for spraying valves of different lengths. At the same time, it prevents impurities flying during spraying from landing on the toothed block and locking tooth and solidifying, thus avoiding a decrease in the mutual limiting effect of the toothed block and locking tooth.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 4As shown, a valve processing coating spraying device according to an embodiment of the present invention includes a spraying frame 1; a pair of support frames 12 are mounted on the top of the spraying frame 1, with one support frame 12 fixedly mounted on the spraying frame 1 and the other support frame 12 movably mounted on the spraying frame 1; a cylinder 13 is rotatably connected to the middle of the support frame 12; a first gear 14 is fixedly connected to the middle of the cylinder 13; a motor 15 is fixedly connected to the side wall of the support frame 12; and a second gear 14 is fixedly connected to the output end of the motor 15. 6; The second gear 16 and the first gear 14 are meshed; Multiple elastic plates 17 are fixedly connected to the inner wall of the cylinder 13; A protrusion 18 is fixedly connected to one end of the elastic plate 17 extending to the outside of the cylinder 13; An adjusting rod 19 is threadedly connected to the middle of the cylinder 13; A top block 110 is rotatably connected to one end of the adjusting rod 19 facing the multiple elastic plates 17; During operation, one end of the valve to be coated is pressed against the side wall of a cylinder 13, and the multiple elastic plates 17 on this cylinder 13 are released from the valve end. The valve is inserted into the valve, and then the adjusting rod 19 is rotated to move the top block 110. After the top block 110 moves between the multiple elastic plates 17, the top block 110 will squeeze the multiple elastic plates 17, causing the multiple elastic plates 17 to move away from each other, and causing the multiple protrusions 18 to squeeze the inner wall of the valve port. The friction between the protrusions 18 and the inner wall of the valve port allows the valve and the cylinder 13 to rotate synchronously. Then, the movable support frame 12 is moved to insert another set of elastic plates 17 into the other port of the valve and the above operation is repeated to support and fix both ends of the valve. Then, the motor 15 is started, and the cylinder 13 and the valve are rotated by the cooperation of the second gear 16 and the first gear 14. The spraying mechanism is used to spray the outer surface of the valve evenly. With the above structure, when spraying the valve, the support mechanism only contacts the inside of the valve and supports the valve, reducing the obstruction of the outer surface of the valve and reducing the impact on the spraying of the outer surface of the valve.

[0024] like Figures 1 to 3As shown, multiple support rods 2 are fixedly connected to the middle of the spraying frame 1; a support frame 12 is slidably connected to the middle of the multiple support rods 2; a mounting plate 21 is fixedly connected to the side wall of this support frame 12; a connecting rod 22 is slidably connected to the middle of the mounting plate 21; a toothed block 23 is fixedly connected to the end of the connecting rod 22; a spring 24 is installed in the middle of the connecting rod 22; multiple locking teeth 25 are fixedly connected to the side wall of the spraying frame 1; during operation, when it is necessary to move the movable support frame 12 to adjust the device, the connecting rod 22 can be pulled to move the toothed block 23 away from the multiple locking teeth 25, and then the support frame 12 installed in the middle of the multiple support rods 2 can be slidably adjusted. After the adjustment is completed, the tension on the connecting rod 22 is released. When pulled, the toothed block 23 will move closer to the multiple locking teeth 25 under the elastic force of the spring 24, and the toothed block 23 will mesh with the multiple locking teeth 25, making it difficult for the toothed block 23 to move. Since the locking teeth 25 and the toothed block 23 are both located on the outer wall of the spraying frame 1, it is difficult for the paint flying during spraying to fall on the toothed block 23 and the locking teeth 25 and solidify. Through the above structure, the external of a support frame 12 can be easily adjusted, so that the device can be used for spraying valves of different lengths. At the same time, it is difficult for impurities flying during spraying to fall on the toothed block 23 and the locking teeth 25 and solidify, which would reduce the mutual limiting effect of the toothed block 23 and the locking teeth 25.

[0025] like Figures 1 to 4 As shown, a fixing ring 3 is fixedly connected to the end of the cylinder 13; multiple slots 31 are provided in the middle of the fixing ring 3; a rod 32 is slidably connected to the side wall of the support frame 12; during operation, when it is necessary to rotate the adjusting rod 19 to adjust the position of the top block 110, the rod 32 can be slid to insert into a slot 31, thereby the rod 32 will obstruct the rotation of the fixing ring 3, making it difficult for the cylinder 13 to rotate easily. Through the above structure, when the adjusting rod 19 is rotated, the rotation of the cylinder 13 can be restricted, reducing the force transmitted to the cylinder 13 during the adjustment of the adjusting rod 19, so that the cylinder 13 rotates synchronously, thereby enabling the top block 110 to move better under force and increasing the friction between the protrusion 18 and the inner wall of the valve, thus improving the support and rotation effect of the valve.

[0026] like Figures 1 to 4 As shown, a metal ring 4 is fixed to the side wall of the cylinder 13; the metal ring 4 is made of magnetic material; a magnet 41 is fixed to the end of the insertion rod 32; during operation, when it is necessary to restrict the rotation of the cylinder 13, the insertion rod 32 needs to be inserted into the slot 31. At this time, the magnet 41 will pass through the insertion rod 32 and be attracted to the metal ring 4 under the action of magnetic force, so that the insertion rod 32 is difficult to slide down and detach from the slot 31. With the above structure, when the adjusting rod 19 is rotated and adjusted, the insertion rod 32 does not need to be continuously supported and is difficult to detach from the slot 31, thus improving the ease of use of the device.

[0027] like Figures 1 to 4 As shown, a top ring 5 is threadedly connected to the middle of the cylinder 13; a rubber pad 51 is fixed to the side wall of the top ring 5; during operation, after the two sets of elastic plates 17 support both ends of the valve, the top ring 5 can be rotated to move closer to the valve end, so that the rubber pad 51 is tightly attached to the valve port. Through the above structure, when spraying the outer surface of the valve, the occurrence of paint entering the valve from the valve port is reduced, thus reducing the impact on the quality of the valve product.

[0028] like Figures 1 to 3 As shown, multiple elastic film sleeves 6 are fixed to the inner wall of the spraying frame 1; the other end of the elastic film sleeve 6 is fixed to the side wall of the support frame 12 installed in the middle of the support rod 2, and the multiple elastic film sleeves 6 respectively surround the multiple support rods 2 inside; during operation, if some of the sprayed paint falls directly onto the support rod 2 and solidifies when spraying the valve, it will have a certain impact on the sliding of the support frame 12. The elastic film sleeves 6 can block the flying paint, making it difficult for the paint to fall onto the support rod 2, thereby reducing the impact of paint solidification on the sliding of the support frame 12.

[0029] like Figure 3 As shown, a partition plate 7 is fixed to the side wall of the spraying frame 1; the partition plate 7 is located above multiple clamping teeth 25; through the above structure, the occurrence of flying paint falling on the tooth block 23 and clamping teeth 25 can be further reduced, and the occurrence of paint solidification causing a decrease in the limiting effect of the tooth block 23 and clamping teeth 25 can be further reduced.

[0030] During operation, one end of the valve to be coated is pressed against the side wall of a cylinder 13, and multiple elastic plates 17 on the cylinder 13 are inserted into the valve port. Then, the adjusting rod 19 is rotated to move the top block 110. After the top block 110 moves between the multiple elastic plates 17, it compresses the plates, causing them to move away from each other. This also causes multiple protrusions 18 to press against the inner wall of the valve port. The friction between the protrusions 18 and the inner wall of the valve port allows the valve and cylinder 13 to rotate synchronously. Then, the movable support frame 12 is moved to allow another... The elastic plate 17 is inserted into the other port of the valve, and the above operation is repeated to support and fix both ends of the valve. Then, the motor 15 is started, and the cylinder 13 and the valve are rotated by the cooperation of the second gear 16 and the first gear 14. The outer surface of the valve is evenly sprayed using the spraying mechanism. When it is necessary to move the movable support frame 12 to move the device, the connecting rod 22 can be pulled to move the tooth block 23 away from the multiple locking teeth 25. Then, the support frame 12 installed in the middle of the multiple support rods 2 is slidably adjusted. After the adjustment is completed, the pull on the connecting rod 22 is released. At this time, the tooth block 23 will be in the spring 24. Under the elastic force, the tooth block 23 moves closer to the multiple locking teeth 25, and the tooth block 23 will mesh with the multiple locking teeth 25, making it difficult for the tooth block 23 to move. Since both the locking teeth 25 and the tooth block 23 are located on the outer wall of the spraying frame 1, it prevents the paint flying during spraying from landing on the tooth block 23 and locking teeth 25 and solidifying. When it is necessary to rotate the adjusting rod 19 to adjust the position of the top block 110, the sliding rod 32 can be inserted into a slot 31, thus the rod 32 will obstruct the rotation of the fixing ring 3, making it difficult for the cylinder 13 to rotate easily. When it is necessary to restrict the rotation of the cylinder 13, it is necessary to... When inserting the rod 32 into the slot 31, the magnet 41 will pass through the rod 32 and be attracted to the metal ring 4 under the action of magnetic force, making it difficult for the rod 32 to slide down and detach from the slot 31. After using two sets of elastic plates 17 to support both ends of the valve, a pair of top rings 5 ​​can be rotated to move closer to the valve end, so that the rubber pad 51 is tightly attached to the valve port. When spraying the valve, if some of the sprayed paint falls directly onto the support rod 2 and solidifies, it will have a certain impact on the sliding of the support frame 12. The elastic film sleeve 6 can block the flying paint, making it difficult for the paint to fall onto the support rod 2.
