Description

Technical Field

[0001] This utility model belongs to the field of valve internal component coating spraying technology, and in particular relates to a valve internal component coating spraying device. Background Technology

[0002] Valves and pipe fittings are currently made of carbon steel, stainless steel, cast steel, PVC and other materials. The first three are the most commonly used materials. In recent years, with the improvement of people's living standards, the requirements for non-staple foods have also increased, which has driven the rapid development of food machinery. As a result, the stainless steel sanitary valve and pipe fitting manufacturing industry has become very popular. The valve and pipe fittings that people usually talk about are still the stainless steel sanitary valve and pipe fittings.

[0003] For example, Chinese patent CN205731768U discloses a valve and pipe fitting lining coating spraying device, including a base, a spraying system, and a pipe fitting support system. The device is characterized in that the spraying system is installed on the right side of the upper surface of the base, and the pipe fitting support system is installed on the left side of the upper surface of the base. Due to the adoption of the above technical solution, this utility model has the following beneficial effects: By cooperating with the spraying system and the pipe fitting support system, this utility model reduces the difficulty of operation, saves time and labor, greatly liberates labor, ensures uniform application of cement, effectively improves production efficiency, and reduces production costs.

[0004] The aforementioned patent has the following problems:

[0005] This patent has some drawbacks in its use, such as: when inserting valve fittings, the device can only accommodate valve fittings of the same diameter; valve fittings of different diameters cannot be placed in the device, making it impossible to spray valve fittings of different diameters. Moreover, during spraying, the rollers squeeze the already sprayed area inside the valve fitting, leaving marks on the sprayed area and affecting the spraying quality of the valve fitting. In addition, when the device sprays the valve fitting, the internal coating forms a mist and evaporates from the valve fitting, causing environmental pollution and affecting human health. In view of this, we propose a valve internal coating spraying device. Utility Model Content

[0006] The purpose of this invention is to provide a valve internal coating spraying device to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides a valve internal component coating spraying device, comprising:

[0008] The base has a support plate one and a support plate two on its top.

[0009] A transmission groove is formed inside a support plate 1. A transmission wheel 1 is rotatably installed inside the transmission groove. A limit plate is fixedly installed on the side of the transmission wheel 1 near the support plate 2. Several sliders 2 are slidably installed inside the limit plate. Slider 1 and a clamping plate are fixedly installed on both sides of slider 2 respectively.

[0010] A power assembly, located within a support plate, is used to drive a transmission wheel to rotate and to drive several sliders to move closer or further apart from each other.

[0011] The protective tube is fixedly installed on the support plate and the limiting plate is located inside the protective tube. The protective tube is provided with several telescopic tubes fixed to the support plate. A loop frame fixed to one end of the protective tube is fixedly installed at one end of the several telescopic tubes.

[0012] A slot is provided on one side of the support plate 2. A clamping frame is provided on one side of the support plate 2 and inside the slot. A plurality of rotating slots are provided in the clamping frame. A sleeve is rotatably installed in the rotating slot. A clamping column that rotates with the support plate 2 is slidably installed in the sleeve. A roller is rotatably installed on one end of the clamping column. A limit block 2 is rotatably installed on one side of the support plate 2.

[0013] A control component, located on the second limiting block, is used to drive the clamping frame to rotate about the second limiting block as an axis;

[0014] A through slot is formed on the second support plate and located in the slot. A protective box connected to the through slot is fixedly installed on one side of the second support plate. A paint box is inserted into the top of the protective box. An electric push rod is fixedly installed on one side of the protective box. The output end of the electric push rod extends through the protective box and the through slot into the clamping frame and is fixedly installed with a spray head.

[0015] A water pump is fixedly installed on a paint tank, with its inlet end connected to the inner cavity of the paint tank. A water pipe is fixedly installed at the outlet end of the water pump, and the water pipe is connected to a spray head via a folded water pipe.

[0016] In this technical solution, a power component is set up to drive several sliders 1 away from each other, which in turn drives their corresponding sliders 2 away from each other, and thus the sliders 2 drive their corresponding clamps away from each other. At this time, the operator places one end of the valve fitting between the clamps, and then drives the power component again to drive the sliders 1 closer to each other, which in turn drives their corresponding sliders 2 closer to each other, so that the sliders 2 drive their corresponding clamps to move closer to the valve fitting until the clamps clamp and fix the valve fitting, and then stops the power component to fix the valve fitting between the clamps.

[0017] Then, the personnel push the second support plate so that the clamping frame on the second support plate can be inserted into the other end of the valve fitting. At this time, through the set control component, the control component drives the clamping frame to rotate around the second limit block as the axis. The clamping frame drives the sleeves in several rotating slots to rotate. The sleeves drive the corresponding clamping columns to rotate on the second support plate. At the same time, the clamping columns slide in the sleeves. The clamping columns drive the corresponding rollers to rotate towards the valve fitting, so that the rollers press against the valve fitting, thereby fixing the valve fitting in the clamping frame.

[0018] Subsequently, the power assembly is driven again, which drives the transmission wheel one to rotate, the transmission wheel one to rotate the limit plate, the limit plate to rotate several sliders two to rotate, and at the same time, the several sliders two to rotate the corresponding slider one and clamping plate, and the several clamping plates together to drive the valve fitting to rotate slowly. The valve fitting rotates slowly on several rollers, and the several rollers also roll on the valve fitting, so that the valve fitting can rotate at a uniform speed within the overall device.

[0019] Subsequently, the personnel pushed the U-shaped frame and inserted it into the slot. The U-shaped frame moved the protective tube and several telescopic tubes toward the slot, causing the protective tube and several telescopic tubes to extend and cover the valve fittings. This prevented the paint from forming mist and evaporating during the spraying of the valve fittings, which would pollute the environment and affect the health of personnel.

[0020] At this point, the operator places the paint into the paint tank, connects the electric actuator to the power supply and starts it. The output end of the electric actuator drives the spray head through the through groove and into the interior of the valve fitting. At the same time, the spray head also drives the folded water pipe to extend. Then, the water pump is connected to the power supply and started. The water pump pumps the paint in the paint tank into the folded water pipe and the spray head through the water pipe, enabling the spray head to perform the spraying work. Because the valve fitting rotates at a uniform speed, the spray head can evenly spray the paint onto the inner wall of the valve fitting. Furthermore, since there are no other parts inside the valve fitting that squeeze it, the entire device will not affect the sprayed area inside the valve fitting during spraying.

[0021] In the above technical solution, the base and the support plate are integrally formed, and a second groove is provided on the top of the base and on one side of the support plate. The support plate is slidably installed in the second groove.

[0022] In this technical solution, the stability of the overall device is ensured, and the second support plate can slide normally on the top of the base.

[0023] In the above technical solution, a second rubber pad is fixedly installed on the clamping plate, a handle is fixedly installed on the U-shaped frame, and the protective tube has a folded structure.

[0024] In this technical solution, the rubber pad II ensures that the valve fittings will not be damaged when the clamps squeeze them. At the same time, due to the large friction between the rubber pad II and the valve fittings, the valve fittings will not easily fall off between the clamps when rotating, ensuring that personnel can easily move the U-shaped frame with the handle, and ensuring that the protective tube can be extended by the U-shaped frame.

[0025] In the above technical solution, the power component further includes:

[0026] The motor is fixedly mounted on one side of the support plate. The output shaft of the motor extends through one side of the support plate to the transmission groove and is coaxially connected to the transmission wheel 2. The transmission wheel 2 is connected to the transmission wheel 1 via a belt.

[0027] A limiting block 1 is fixedly installed on a transmission wheel 1 on the side away from the limiting plate. A push rod is slidably installed on the limiting block 1, and one end of the push rod passes through the transmission wheel 1 and is fixed to the push plate. The push plate is located between several sliders 1.

[0028] A threaded rod is threadedly installed on one side of a limiting block, and a rubber pad that contacts the push rod is fixedly installed at one end of the threaded rod.

[0029] In this technical solution, first rotate the threaded rod one so that one end of the threaded rod one drives the rubber pad one away from the push rod, thereby releasing the limit of the threaded rod one to the push rod. At this time, push or pull the push rod, and the push rod drives the push plate to move closer to or away from the limit plate. The push plate drives several sliders on the periphery to move closer to or away from each other, ensuring that the valve fitting can be fixed between several clamps.

[0030] When the motor is connected to the power supply and started, the output shaft of the motor drives the second transmission wheel to rotate. The second transmission wheel drives the first transmission wheel to rotate via a belt. The first transmission wheel drives the first limit block and the limit disc to rotate. The first limit block drives the first threaded rod to rotate. The limit disc drives several second sliders to rotate. The several second sliders drive the corresponding first sliders and clamping plates to rotate. The several first sliders together drive the push plate to rotate. The push plate drives the push rod to rotate. At the same time, the clamping plates drive the valve fittings to rotate slowly, so that the valve fittings rotate at a uniform speed within the overall device.

[0031] In the above technical solution, the output shaft of the motor is rotatably connected to the support plate, the push rod is slidably connected to the transmission wheel, the push plate is slidably connected to several sliders, and the periphery of the push plate and the several sliders are all inclined.

[0032] In this technical solution, it is ensured that the output shaft of the motor can rotate normally within the support plate, that the push rod can slide normally within the transmission wheel, and that under the action of compression, the push plate can drive several sliders to move closer or further apart.

[0033] In the above technical solution, the herringbone frame is inserted into the slot, the cross-sectional dimensions of the herringbone frame and the slot are equal, and the number of the plurality of rotating slots is at least three.

[0034] In this technical solution, it is ensured that the U-shaped frame can be inserted into the slot, and that there is no gap between the U-shaped frame and the slot to prevent the paint from evaporating into mist; it is also ensured that the valve fittings can be stably clamped.

[0035] In the above technical solution, the control component further includes:

[0036] A rotating block is fixedly mounted on a clamping frame, and a limit block three is rotatably mounted on one side of the rotating block;

[0037] Threaded rod two is rotatably mounted on limiting block two, and one end of threaded rod two passes through limiting block three.

[0038] In this technical solution, when the clamping frame is inserted into the other end of the valve fitting, the threaded rod two is rotated. Under the action of the thread, the threaded rod two drives the limiting block three away from the limiting block two on the threaded rod two. The limiting block three then drives the rotating block away from the limiting block two, and the rotating block presses the clamping frame downward to rotate around the limiting block two as the axis, ensuring that the limiting block three, the rotating block, and the clamping frame all rotate around the limiting block two as the axis. The clamping frame drives the corresponding sleeves in several rotating grooves to rotate, and the several sleeves drive the corresponding clamping columns to rotate. At the same time, the several clamping columns slide in the corresponding sleeves, thereby causing the several clamping columns to drive the corresponding rollers to rotate towards the valve fitting, so that the valve fitting is fixed in the clamping frame by the several rollers.

[0039] In the above technical solution, the limiting block three is further threadedly connected to the threaded rod two.

[0040] In this technical solution, it is ensured that the limiting block three can move stably on the threaded rod two.

[0041] In the above technical solution, further, the output end of the electric push rod is slidably connected to the protective box, the feed end of the water pump is threadedly connected to the paint box, the discharge end of the water pump is threadedly connected to one end of the water pipe, the other end of the water pipe is threadedly connected to one end of the folded water pipe, the other end of the folded water pipe is threadedly connected to the spray head, and the folded water pipe has a folded structure.

[0042] In this technical solution, it is ensured that the output end of the electric push rod can slide normally inside the protective box, that the water pump, water pipe, and folded water pipe can be easily removed when damaged, and that the folded water pipe can be extended by the spray head.

[0043] The beneficial effects of this utility model are:

[0044] 1. This valve internal coating spraying device, through the cooperation of a power component with transmission wheel one, limit block one, limit plate, slider one, slider two, and clamping plate, can drive several clamping plates to clamp and fix one end of valve pipes of different diameters and drive the valve pipes to rotate slowly. Meanwhile, the control component, through the cooperation of a clamping frame, rotating block, sleeve, clamping column, roller, and limit block two, can drive several rollers to clamp and fix the other end of valve pipes of different diameters within the clamping frame. Subsequently, through the cooperation of a paint tank, protective box, electric push rod, spray head, water pump, water pipe, folding water pipe, and through groove, it is ensured that the spray head can uniformly spray paint inside the slowly rotating valve pipes of different diameters. Furthermore, since there are no other components inside the valve pipes of different diameters that squeeze the valve pipes, the entire device will not affect the sprayed areas inside the valve pipes of different diameters during spraying, ensuring the coating quality of the valve pipes.

[0045] 2. In this valve internal coating spraying device, when spraying valve fittings, a protective tube is installed. After the valve fitting is clamped onto the overall device, the handle is moved to drive the U-shaped frame to insert into the slot. The U-shaped frame causes the protective tube and several telescopic tubes to extend, so that the protective tube covers the outside of the valve fitting, thereby preventing the leakage of paint mist generated by the device during spraying. At the same time, a small amount of paint mist is allowed to enter the protective box. Since the paint box is inserted into the protective box, and the protective box is fixed on the support plate 2, the paint mist in the protective box will not evaporate outside the overall device, ensuring that the overall device does not affect the environment and personnel health during operation.

[0067] Please see Figures 1-14 As shown, this embodiment provides a valve internals coating spraying device, including:

[0068] The base 1 has a support plate 2 and a support plate 3 on its top.

[0069] Transmission groove 17 is opened in support plate 1 2. Transmission wheel 1 4 is rotatably installed in transmission groove 17. Limiting plate 9 is fixedly installed on the side of transmission wheel 1 4 near support plate 2 3. Several sliders 2 11 are slidably installed in limiting plate 9. Slider 1 10 and clamping plate 12 are fixedly installed on both sides of slider 2 11 respectively.

[0070] The power assembly is located inside the support plate 2 and is used to drive the transmission wheel 4 to rotate and drive several sliders 10 to move closer or further apart.

[0071] The protective tube 20 is fixedly installed on the support plate 2, and the limiting plate 9 is located inside the protective tube 20. The protective tube 20 is provided with several telescopic tubes 19 fixed to the support plate 2. One end of the protective tube 20 is fixedly installed with a loop frame 18 that is fixed to one end of several telescopic tubes 19.

[0072] A slot 22 is provided on one side of the support plate 2 3. A clamping frame 27 is provided on one side of the support plate 2 3 and inside the slot 22. Several rotating slots 28 are provided in the clamping frame 27. A sleeve 29 is rotatably installed in the rotating slot 28. A clamping post 30 that rotates with the support plate 2 3 is slidably installed in the sleeve 29. A roller 31 is rotatably installed on one end of the clamping post 30. A limit block 23 is rotatably installed on one side of the support plate 2 3.

[0073] The control component is located on the second limit block 23 and is used to drive the clamping frame 27 to rotate around the second limit block 23 as the axis.

[0074] A through groove 40 is formed on the support plate 23 and located in the slot 22. A protective box 34 connected to the through groove 40 is fixedly installed on one side of the support plate 23. A paint box 33 is inserted into the top of the protective box 34. An electric push rod 35 is fixedly installed on one side of the protective box 34. The output end of the electric push rod 35 extends through the protective box 34 and the through groove 40 into the clamping frame 27 and is fixedly installed with a spray head 36.

[0075] A water pump 37 is fixedly installed on a paint tank 33, and the inlet end of the water pump 37 is connected to the inner cavity of the paint tank 33. A water pipe 38 is fixedly installed on the outlet end of the water pump 37, and the water pipe 38 is connected to the spray head 36 through a folded water pipe 39.

[0076] The system is designed with a power assembly that drives several sliders 10 to move away from each other. These sliders 10 then move their corresponding sliders 2 11 away from each other, which in turn moves their corresponding clamping plates 12 away from each other. At this point, the operator places one end of the valve fitting between the clamping plates 12. The power assembly is then driven again, causing the sliders 10 to move closer to each other. These sliders 10 then move their corresponding sliders 2 11 closer to each other, which in turn moves their corresponding clamping plates 12 towards the valve fitting until the clamping plates 12 clamp and fix the valve fitting in place. The power assembly is then stopped, allowing the valve fitting to be fixed between the clamping plates 12.

[0077] Then, the personnel push the support plate 23 so that the clamping frame 27 on the support plate 23 can be inserted into the other end of the valve fitting. At this time, through the set control component, the control component drives the clamping frame 27 to rotate around the limit block 23 as the axis. The clamping frame 27 drives the sleeves 29 in the several rotating grooves 28 to rotate. The several sleeves 29 drive the corresponding clamping columns 30 to rotate on the support plate 23. At the same time, the clamping columns 30 slide in the sleeves 29. The several clamping columns 30 drive the corresponding rollers 31 to rotate towards the valve fitting, so that the several rollers 31 press on the valve fitting, thereby fixing the valve fitting in the clamping frame 27.

[0078] Subsequently, the power assembly is driven again, which drives the transmission wheel 4 to rotate, the transmission wheel 4 to rotate the limiting plate 9, the limiting plate 9 to rotate the several sliders 11, and at the same time, the several sliders 11 drive the corresponding sliders 10 and clamping plates 12 to rotate. The several clamping plates 12 together drive the valve fitting to rotate slowly. The valve fitting rotates slowly on several rollers 31, and the several rollers 31 also roll on the valve fitting, so that the valve fitting can rotate at a uniform speed within the overall device.

[0079] Subsequently, the personnel push the U-shaped frame 18 and insert it into the slot 22. The U-shaped frame 18 drives the protective tube 20 and several telescopic tubes 19 to move towards the slot 22, so that the protective tube 20 and several telescopic tubes 19 extend and the protective tube 20 covers the valve fittings, so as to prevent the paint from forming mist and evaporating when spraying the valve fittings, which would pollute the environment and affect the health of personnel.

[0080] At this time, the personnel put the paint into the paint tank 33, connect the electric push rod 35 to the power supply and start it. The output end of the electric push rod 35 drives the spray head 36 through the through groove 40 and into the interior of the valve fitting. At the same time, the spray head 36 also drives the folded water pipe 39 to extend. Then, the water pump 37 is connected to the power supply and started. The water pump 37 pumps the paint in the paint tank 33 into the folded water pipe 39 and the spray head 36 through the water pipe 38, so that the spray head 36 can carry out the spraying work. Since the valve fitting rotates at a uniform speed, the spray head 36 can evenly spray the paint onto the inner wall of the valve fitting. And since there are no other parts inside the valve fitting that squeeze the valve fitting, the whole device will not affect the area inside the valve fitting that has been sprayed during spraying. Example 2

[0081] This embodiment provides a valve internal coating spraying device. In addition to the technical solution of the above embodiment, it also has the following technical features: the base 1 and the support plate 2 are integrally formed. The top of the base 1 and one side of the support plate 2 are provided with a sliding groove 32. The support plate 3 is slidably installed in the sliding groove 32.

[0082] Among these measures, ensuring the stability of the overall device is crucial, ensuring that the support plate 2 3 can slide normally on the top of the base 1. Example 3

[0083] This embodiment provides a valve internal coating spraying device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: a rubber pad 13 is fixedly installed on the clamping plate 12, a handle 21 is fixedly installed on the U-shaped frame 18, and the protective tube 20 has a folded structure.

[0084] The rubber pad 13 ensures that the valve fittings are not damaged when the clamping plates 12 squeeze them. At the same time, the large friction between the rubber pad 13 and the valve fittings prevents the valve fittings from easily falling off between the clamping plates 12 when rotating. This ensures that personnel can easily move the U-shaped frame 18 through the handle 21, and that the protective tube 20 can be extended by the U-shaped frame 18.

[0085] It is worth noting that the protective tube 20 is made of transparent elastic material. When the protective tube 20 is stretched by the herringbone frame 18, it can automatically retract under the action of its own elasticity without any external force. Example 4

[0086] This embodiment provides a valve internals coating spraying device, which, in addition to the technical solutions of the above embodiments, also has the following technical features, including a power component:

[0087] Motor 14 is fixedly installed on one side of support plate 2. The output shaft of motor 14 extends through one side of support plate 2 to transmission groove 17 and is coaxially connected to transmission wheel 15. Transmission wheel 15 is connected to transmission wheel 4 via belt 16.

[0088] Limiting block 5 is fixedly installed on the transmission wheel 4 and away from the limiting plate 9. A push rod 6 is slidably installed on the limiting block 5, and one end of the push rod 6 passes through the transmission wheel 4 and is fixed to the push plate 8. The push plate 8 is located between several sliders 10.

[0089] Threaded rod 7 is threadedly installed on one side of limit block 5, and one end of threaded rod 7 is fixedly installed with rubber pad 71 that contacts push rod 6.

[0090] First, rotate the threaded rod 7 so that one end of the threaded rod 7 drives the rubber pad 71 away from the push rod 6, thereby releasing the threaded rod 7 from limiting the push rod 6. At this time, push or pull the push rod 6, and the push rod 6 drives the push plate 8 to move closer to or away from the limiting plate 9. The push plate 8 drives several sliders 10 on the periphery to move closer to or away from each other, ensuring that the valve fitting can be fixed between several clamping plates 12.

[0091] When the motor 14 is powered on and started, the output shaft of the motor 14 drives the transmission wheel 15 to rotate. The transmission wheel 15 drives the transmission wheel 4 to rotate via the belt 16. The transmission wheel 4 drives the limit block 5 and the limit plate 9 to rotate. The limit block 5 drives the threaded rod 7 to rotate. The limit plate 9 drives several sliders 11 to rotate. The several sliders 11 drive the corresponding sliders 10 and the clamping plate 12 to rotate. The several sliders 10 together drive the push plate 8 to rotate. The push plate 8 drives the push rod 6 to rotate. At the same time, the clamping plates 12 drive the valve fittings to rotate slowly, so that the valve fittings rotate at a uniform speed within the overall device.

[0092] It is worth noting that if the motor 14 is damaged and cannot be replaced in time, the operator can manually rotate the push rod 6, which in turn drives the push plate 8 to rotate. The push plate 8, through several sliders 10, drives the corresponding sliders 11 to rotate. The sliders 11 are located within the limiting plate 9 and will drive the limiting plate 9 and the corresponding clamping plate 12 to rotate. The clamping plate 12 will fix the valve fittings in place. Therefore, the clamping plate 12 will drive the valve fittings to rotate. At the same time, the limiting plate 9 will also drive the transmission wheel 4 to rotate, ensuring that the entire device can operate normally in a short period of time and ensuring that the company will not stop producing valve fittings and suffer economic losses. Example 5

[0093] This embodiment provides a valve internal coating spraying device. In addition to the technical solutions of the above embodiments, it also has the following technical features: the output shaft of the motor 14 is rotatably connected to the support plate 2, the push rod 6 is slidably connected to the transmission wheel 4, the push plate 8 is slidably connected to a plurality of sliders 10, and the periphery of the push plate 8 and the plurality of sliders 10 are all inclined.

[0094] Specifically, it ensures that the output shaft of motor 14 can rotate normally within support plate 2, that push rod 6 can slide normally within transmission wheel 4, and that under the action of compression, push plate 8 can drive several sliders 10 to move closer or further apart. Example 6

[0095] This embodiment provides a valve internal coating spraying device, which, in addition to the technical solution of the above embodiment, also has the following technical features: the spiral frame 18 and the slot 22 are inserted and matched, the cross-sectional dimensions of the spiral frame 18 and the slot 22 are equal, and the number of the plurality of rotating slots 28 is at least 3.

[0096] Specifically, it ensures that the spiral frame 18 can be inserted into the slot 22 and that there is no gap between the spiral frame 18 and the slot 22 to prevent the paint from forming mist and evaporating; and it ensures that the valve fittings can be stably clamped. Example 7

[0097] This embodiment provides a valve internals coating spraying device, which, in addition to the technical solutions of the above embodiments, also has the following technical features, including a control component:

[0098] Rotating block 26 is fixedly installed on clamping frame 27, and limit block 3 24 is rotatably installed on one side of rotating block 26;

[0099] Threaded rod 25 is rotatably mounted on limit block 23, and one end of threaded rod 25 passes through limit block 3 24.

[0100] When the clamping frame 27 is fitted onto the other end of the valve fitting, the threaded rod 25 is rotated. Under the action of the thread, the threaded rod 25 drives the limiting block 24 away from the limiting block 23 on the threaded rod 25. The limiting block 24 then drives the rotating block 26 away from the limiting block 23, and the rotating block 26 presses the clamping frame 27 downward to rotate around the limiting block 23. This ensures that the limiting block 24, the rotating block 26, and the clamping frame 27 all rotate around the limiting block 23. The clamping frame 27 drives the corresponding sleeves 29 in the rotating grooves 28 to rotate. The sleeves 29 drive the corresponding clamping posts 30 to rotate. At the same time, the clamping posts 30 slide in the corresponding sleeves 29, thereby causing the clamping posts 30 to drive the corresponding rollers 31 to rotate towards the valve fitting. This fixes the valve fitting in the clamping frame 27 by the rollers 31. Example 8

[0101] This embodiment provides a valve internal coating spraying device, which, in addition to the technical solution of the above embodiment, also has the following technical features: the limiting block 3 24 is threadedly connected to the threaded rod 25.

[0102] Among them, it ensures that the limiting block 3 24 can move stably on the threaded rod 25. Example 9

[0103] This embodiment provides a valve internal coating spraying device. In addition to the technical solutions of the above embodiments, it also has the following technical features: the output end of the electric push rod 35 is slidably connected to the protective box 34; the feed end of the water pump 37 is threadedly connected to the paint box 33; the discharge end of the water pump 37 is threadedly connected to one end of the water pipe 38; the other end of the water pipe 38 is threadedly connected to one end of the folded water pipe 39; the other end of the folded water pipe 39 is threadedly connected to the spray head 36; and the folded water pipe 39 has a folded structure.

[0104] Specifically, it ensures that the output end of the electric push rod 35 can slide normally within the protection box 34, that the water pump 37, water pipe 38, and folded water pipe 39 can be easily removed when damaged, and that the folded water pipe 39 can be extended by the spray head 36.

[0105] It is worth noting that the folded water pipe 39 is made of elastic material. When the spray head 36 causes the folded water pipe 39 to retract, the folded water pipe 39 can automatically retract under the action of elasticity, preventing the folded water pipe 39 from bending and avoiding contact between the folded water pipe 39 and the inner wall of the valve fitting.

[0106] Working principle: The operator first rotates the threaded rod 7. Under the action of the thread, one end of the threaded rod 7 moves one end of the rubber pad 71 away from the push rod 6, thus releasing the limit on the push rod 6. Then, the operator pulls the push rod 6 away from the limiting plate 9. The push rod 6 drives the push plate 8 to move away from the limiting plate 9. At the same time, the push plate 8 slides between several sliders 10. Under the action of compression, the sliders 10 drive the corresponding sliders 11 to slide within the corresponding limiting plates 9, causing the sliders 11 to drive the corresponding clamping plates 12 away from each other. Then, the operator places one end of the valve fitting between the clamping plates 12. At this point, the operator moves it closer to... The push rod 6 is pushed in the direction of the limiting plate 9. The push rod 6 drives the push plate 8 to slide in the direction of the limiting plate 9. The push plate 8 drives several sliders 10 to move closer to each other. The sliders 10 drive the corresponding sliders 11 to move closer to each other in the corresponding limiting plate 9. This causes several clamping plates 12 to move and move closer to the valve fittings until the rubber pads 13 on the clamping plates 12 are pressed against the valve fittings and deformed. Then the push rod 6 is stopped, and the threaded rod 7 is rotated in the opposite direction until the rubber pads 71 ​​on the threaded rod 7 are pressed against the push rod 6 and deformed. This ensures that the push rod 6 is fixed in the limiting block 5. The above process can clamp valve fittings of different diameters.

[0107] Subsequently, the operator pushes the support plate 23 to slide on the slide groove 22 until the clamping assembly can be inserted from the other end of the valve fitting. When the other end of the valve fitting enters the clamping frame 27 and is positioned between several rollers 31, the operator rotates the threaded rod 25. Under the action of the thread, the threaded rod 25 drives the limiting block 34 to move away from the limiting block 23. The limiting block 324 also drives the rotating block 26 to press down on the clamping frame 27 to rotate, ensuring the limiting position. Block 24, rotating block 26, and clamping frame 27 all rotate around limiting block 23. At this time, clamping frame 27 drives several sleeves 29 to rotate, and several sleeves 29 drive the corresponding clamping columns 30 to rotate on support plate 23. At the same time, several clamping columns 30 slide in the corresponding sleeves 29, and several clamping columns 30 drive the corresponding rollers 31 to move closer to the valve fitting until several rollers 31 squeeze the valve fitting, so that the valve fitting is clamped in clamping frame 27.

[0108] Then, the operator connects and starts the motor 14. The output shaft of the motor 14 drives the transmission wheel 15 to rotate. The transmission wheel 15 drives the transmission wheel 4 to rotate via the belt 16. The transmission wheel 4 drives the limiting disc 9 and the limiting block 5 to rotate. The limiting block 5 drives the threaded rod 7 to rotate. The limiting disc 9 drives several sliders 11 to rotate. The several sliders 11 drive the corresponding clamping plates 12 and the corresponding sliders 10 to rotate. The several sliders 10 together drive the push plate 8 to rotate. The push plate 8 drives the push rod 6 to rotate, so that the motor 14 can drive the rotating assembly to rotate. At the same time, the clamping plates 12 drive the valve fittings to rotate. The valve fittings will rotate between several rollers 31, and several Roller 31 also rolls on the valve fitting, allowing the valve fitting to rotate at a uniform speed within the overall device. Then, the operator pulls handle 21, which moves the U-shaped frame 18 towards the support plate 2 3. The U-shaped frame 18 moves several telescopic tubes 19 towards the support plate 2 3, extending them to support the protective tube 20. The U-shaped frame 18 moves the protective tube 20 towards the support plate 2 3, and the protective tube 20 also extends until the U-shaped frame 18 is inserted into the slot 22, thus sealing the valve fitting and preventing the paint mist from evaporating during spraying.

[0109] At this time, the personnel put the paint into the paint tank 33, connect the electric push rod 35 and the water pump 37 to the power supply and start them. The output shaft of the electric push rod 35 will drive the spray head 36 through the through groove 40 and into the inside of the valve fitting. At the same time, the spray head 36 also drives the folded water pipe 39 to extend. The water pump 37 pumps the paint in the paint tank 33 into the water pipe 38, and then transports it to the folded water pipe 39. Finally, the spray head 36 sprays the inner wall of the valve fitting. At the same time, since the valve fitting is rotating at a uniform speed, the spray head 36 can spray the paint evenly into the inside of the valve fitting. And since there are no other parts inside the valve fitting that squeeze the valve fitting, the whole device will not affect the sprayed area inside the valve fitting during spraying.

[0110] It is worth noting that the folded water pipe 39 is made of elastic material. When the spray head 36 causes the folded water pipe 39 to retract, the folded water pipe 39 can automatically retract under the action of elasticity, preventing the folded water pipe 39 from bending and avoiding contact between the folded water pipe 39 and the inner wall of the valve fitting.
