Description

Technical Field

[0002] In order to extend the service life of standard parts, it is necessary to use standard parts spraying equipment to spray paint on the surface of standard parts. The sprayed paint can prevent the surface of standard parts from being corroded by water, salt spray, gas, microorganisms, etc. in the atmosphere, thereby extending the service life of standard parts. There are various types of standard parts, and the spraying equipment used is also different.

[0003] The prior art also proposes some solutions. For example, a patent application with publication number CN117443620A discloses a rotary spraying device for the production of automobile standard parts, including a shell, a shell cover, a storage box and a sprayer. The application improves the continuity of spraying and reduces the workload of manual loading through automatic loading.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. The standard parts spraying equipment described in the present invention fixes the distance between a limit rod and a spray head. The limit rod is always in contact with the tubular standard parts, and the distance between the spray head and the tubular standard parts is always the same. No matter whether the tubular standard parts are thick or thin, the limit rod is always in contact with the side wall of the tubular standard parts for spraying, so as to ensure the constant spraying distance. By keeping the distance between the spray head and the tubular standard parts constant, the equipment can keep the same spraying distance when spraying tubular standard parts of any thickness, which not only ensures the spraying thickness of the tubular standard parts, but also avoids the problem of frequently adjusting the position of the spray head, increasing the workload and time cost of the operator, and reducing the spraying efficiency.

[0019] 2. The standard parts spraying equipment described in the present invention has a limit rod 1 that contacts the outer surface of the tubular standard part. When the spray head moves backward due to the influence of the side wall of the tubular standard part, the limit rod 2 also moves with it. The position of the limit rod 1 is the same as that of the limit rod 2. When the spray head moves from right to left, the limit rod 1 contacts the side wall of the tubular standard part first, and the ball 2 at the end of the limit rod 2 contacts the side wall of the tubular standard part later. When the limit rod 1 moves away from the side wall of the tubular standard part, the limit rod 2 still contacts the side wall of the tubular standard part. At this time, the spray head is affected by the limit rod 2, and the position of the spray head is maintained in the state when it is affected by the limit rod 1. The limit rod 2 prevents the limit rod 1 from moving away from the side wall of the tubular standard part. The spray head that loses the effect of the limit rod 1 cannot maintain a constant distance with the tubular standard part, which affects the spraying, and Moreover, the limit rod 1 preferentially contacts the side wall of the tubular standard part, and the position where the limit rod 2 contacts is the surface of the tubular standard part after painting. In order to prevent the paint surface from being affected by the limit rod 2, the groove is used to dry the surface contacted by the ball 2 at the two ends of the limit rod to accelerate the solidification speed of the paint surface. At the same time, the exhaust fan is used to continuously exhaust air through the connecting pipe, and the paint surface around the support rod is sucked by the air inlet pipe to accelerate the flow rate of the gas, and the drying of the groove is used to improve the solidification effect of the paint surface to prevent the limit rod 2 from damaging the integrity of the paint surface when passing through the uncondensed paint surface. Among them, the exhaust fan, in conjunction with the air inlet pipe, the connecting pipe and the exhaust fan, can also draw the gas generated by spraying paint into the purification box, and use the activated carbon filter in the purification box to filter and purify the gas, so as to reduce the impact of the gas generated by spraying paint on the staff and the environment.

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] like Figures 1 to 9 As shown, a standard parts spraying equipment of an embodiment of the present invention includes a spraying chamber 1, fixed components 2 arranged on both sides of the spraying chamber 1, a frame 3 arranged at the front end of the spraying chamber 1, a movable component 4 arranged on the top of the frame 3, and a spray head 5 arranged on the movable component 4, a spraying component 9 is arranged inside the spray head 5, a limiting component 6 is arranged on one side of the spray head 5, a switch component 10 is arranged at the bottom of the limiting component 6, a compensation component 7 is arranged on the other side of the spray head 5, and a drying component 8 is arranged on one side of the compensation component 7.

[0033] When spraying tubular standard parts, the distance between the nozzle and the standard parts is far or close, which will have a certain impact on the thickness of the spraying. In addition, different types of tubular standard parts have different thicknesses. In order to ensure the spraying effect, the position of the nozzle needs to be adjusted. However, constantly and automatically adjusting the position of the nozzle will interrupt the continuity of the spraying, increase the workload and time cost of the operator, and reduce the spraying efficiency.

[0034] To this end, by keeping the distance between the spray head 5 and the tubular standard part constant, the equipment can keep the same spray distance when spraying tubular standard parts of any thickness, which can not only ensure the spray thickness of the tubular standard parts, but also avoid the problem of frequently adjusting the position of the spray head 5, increasing the workload and time cost of the operator, and reducing the spraying efficiency;

[0035] First, place the tubular standard part between the two fixed components 2 in the spray chamber 1, use the fixed component 2 to clamp the tubular standard part, use the moving component 4 to drive the spray head 5 to move to the right side of the tubular standard part, so that the spray head 5 can move from the right side to the left side of the tubular standard part. The purpose of this design is to ensure that the limit component 6 contacts the tubular standard part first, thereby limiting the spray head 5, and use the moving component 4 to push the spray head 5 to move toward the position of the tubular standard part, so that the limit component 6 conflicts with the outer surface of the tubular standard part. Under the influence of the side wall of the tubular standard part, the limit component 6 cooperates with the spray head 5 to move backward. The movement of the spray head 5 connects the spray component 9. When the switch in the switch component 10 is triggered, the spray component 9 is turned on to spray the paint, and at the same time, the moving component 4 is cooperated to move the spray head 5 from the right side to the left side on the outer surface of the tubular standard part for spraying.

[0036] Among them, the limiting component 6 conflicts with the outer surface of the tubular standard part, and when it moves backward under the influence of the side wall of the tubular standard part, the compensation component 7 also moves with it. The position of the limiting component 6 and the compensation component 7 are the same. When the spray head 5 moves from right to left, the limiting component 6 contacts the side wall of the tubular standard part first, and the compensation component 7 contacts the side wall of the tubular standard part afterwards. When the limiting component 6 is removed from the side wall of the tubular standard part, the compensation component 7 still contacts the side wall of the tubular standard part. At this time, the spray head 5 is affected by the compensation component 7, and the position of the spray head 5 is maintained in the state when it is affected by the limiting component 6. The compensation component 7 prevents the limiting component 6 from being removed from the side wall of the tubular standard part. The spray head 5 that loses the effect of the limiting component 6 cannot maintain a constant distance with the tubular standard part, which affects the spraying.

[0037] Since the limiting component 6 preferentially contacts the side wall of the tubular standard part, the position contacted by the compensation component 7 is the surface of the tubular standard part after painting. In order to prevent the paint surface from being affected by the compensation component 7, the drying component 8 is used to dry the surface contacted by the compensation component 7 to prevent the compensation component 7 from damaging the integrity of the paint surface when passing through the uncondensed paint surface.

[0038] like Figure 1 to Figure 2 As shown, the fixing assembly 2 includes a telescopic rod 21 installed on both sides of the spraying room 1, the output end of the telescopic rod 21 extends to the interior of the spraying room 1 and is installed with a fixed top block 22, and the two fixed top blocks 22 correspond to each other.

[0039] The tubular standard part is placed between the two fixed top blocks 22 in the spray chamber 1, and the telescopic rod 21 is started to push the fixed top block 22 toward the two ends of the tubular standard part. The fixed top block 22 and the two side walls of the tubular standard part are tightly pressed against each other to clamp it. It should be noted that a motor or other rotating components can be installed on the fixed top block 22, so that the clamped tubular standard part can be rotated and turned over after one part is sprayed to spray other parts.

[0040] like Figures 1 to 3 As shown, the moving assembly 4 includes a screw rod 42 arranged on the top of the frame 3, the external thread of the screw rod 42 is connected to the moving frame 41, the moving frame 41 is placed in the frame 3, the spray head 5 is arranged at the rear end of the moving frame 41, the front and rear ends of the screw rod 42 are fixed with threaded sleeves 43, the internal thread of the threaded sleeve 43 is connected to the screw rod 44, and the screw rod 44 is installed at the front and rear ends of the top of the frame 3.

[0041] The spray head 5 is installed on the mobile frame 41 through the limit assembly 6. The rotation of the screw rod 42 drives the threaded mobile frame 41 to move forward and backward. The forward and backward movement of the mobile frame 41 can drive the spray head 5 to move forward and backward. The rotation of the screw rod 44 drives the threaded sleeves 43 at both ends of the screw rod 42 to move horizontally, which can drive the mobile frame 41 on the screw rod 42 to move horizontally. The spray head 5 set on the mobile frame 41 can move horizontally. When spraying the tubular standard parts, first use the threaded sleeve 43 and the screw rod 44 to move the spray head 5 to the right side of the tubular standard parts, so that the limit assembly 6 is first aligned with the side wall of the tubular standard part, and then the movable frame 41 and the screw rod 1 42 are used to push the spray head 5 to move toward the position of the tubular standard part, so that the limit assembly 6 conflicts with the tubular standard part. Affected by the side wall of the tubular standard part, the limit assembly 6 cooperates to move the spray head 5 backward. The movement of the spray head 5 will connect the spray assembly 9. When the switch in the switch assembly 10 is triggered, the spray assembly 9 is turned on to spray the paint. At this time, the threaded sleeve 43 and the screw rod 2 44 are used to move the spray head 5 from the right side of the tubular standard part to the left side for spraying.

[0042] like Figures 5 to 9As shown, the spray assembly 9 includes a nozzle 98 opened in the spray head 5, a docking joint 96 is fixed at the front of the spray head 5, the docking joint 96 is connected to the nozzle 98, a paint inlet 97 is installed at the front of the docking joint 96, a connector 94 is provided at the front end of the docking joint 96, the connector 94 is fixed on the mobile frame 41, a paint discharge port 95 is fixed at the back of the connector 94, the paint discharge port 95 is connected to the inside of the connector 94, and the number of the paint discharge ports 95 and the paint inlet port 97 are the same and correspond one to one, and a valve plate 99 is provided inside the paint discharge port 95, and the valve plate 99 is provided inside the paint discharge port 95. A rotating pin 910 is fixed on both sides of the top of the plate 99, and the rotating pin 910 is rotatably set inside the rotating groove 911. The rotating groove 911 is opened on the side wall of the paint discharge port 95. A coil spring 912 is fixed inside the rotating groove 911, and the coil spring 912 is wound around the outside of the rotating pin 910. The spraying assembly 9 also includes a paint storage tank 91 installed on the front of the movable frame 41. A pump body 92 is arranged below the paint storage tank 91. The pump body 92 is installed on the movable frame 41. The pump body 92 is connected to the inside of the paint storage tank 91, and an injection pipe 93 is installed at the output end of the pump body 92.

[0043] The moving assembly 4 pushes the spray head 5 to move toward the position of the tubular standard part, so that the limit assembly 6 conflicts with the outer surface of the tubular standard part. Affected by the side wall of the tubular standard part, the limit assembly 6 cooperates to move the spray head 5 backward. The backward movement of the spray head 5 will drive the docking joint 96 and the paint inlet 97 to move toward the position of the connecting head 94 and the paint discharge port 95. When the paint inlet 97 is inserted into the paint discharge port 95, the docking joint 96 and the connecting head 94 are connected with the paint inlet 97 and the paint discharge port 95. At the same time, the switch of the switch assembly 10 is triggered, and the pump body 92 is started by the switch assembly 10. The pump body 92 extracts the spray material in the paint storage tank 91 and introduces the spray material into the connecting head 94 through the injection pipe 93. The spray material enters the nozzle 98 from the paint discharge port 95, the paint inlet 97 and the docking joint 96 in turn, and the spray material is sprayed out from the nozzle 98 at the end of the spray head 5 and sprayed onto the surface of the tubular standard part. At this time, the moving assembly 4 is cooperated to drive the spray head 5 to move horizontally for spraying.

[0044] When the paint inlet 97 is inserted into the paint discharge port 95, the valve plate 99 will be lifted up. At this time, the paint discharge port 95 loses the blockage of the valve plate 99 and opens. When the valve plate 99 rotates in the rotation groove 911 by relying on the turn pin 910, the turn pin 910 will drive the coil spring 912 to rotate and tighten. When the paint inlet 97 is removed from the paint discharge port 95, the torsional force of the coil spring 912 is used to drive the turn pin 910 to reverse and cause the valve plate 99 to rotate again to the front of the paint discharge port 95 to block it.

[0045] like Figures 3 to 9As shown, the limiting assembly 6 includes a sleeve block 62 fixed at the bottom of the spray head 5, a pillar 61 passes through the interior of the sleeve block 62, the pillar 61 is fixed to the back of the movable frame 41, a spring 63 is wound around the outside of the pillar 61, one end of the spring 63 is fixedly connected to the end of the pillar 61, and the other end of the spring 63 is fixedly connected to the sleeve block 62, a side block 64 is fixed to one side of the spray head 5, a limiting rod 65 is arranged inside the side block 64, a ball 67 is embedded in the end of the limiting rod 65 facing the spray chamber 1, and telescopic rods 66 are installed at the top and bottom of the front part of the side block 64.

[0046] The spray head 5 moves to the right side of the tubular standard part, aligning the end of the limit rod 65 with the side wall of the tubular standard part, and then uses the movable frame 41 and the screw 42 to push the spray head 5 toward the position of the tubular standard part. The spray head 5 will drive the limit rod 65 to move toward the side wall of the tubular standard part, and the ball 67 at the end of the limit rod 65 will preferentially contact the side wall of the tubular standard part. During the continuous forward movement of the spray head 5, the limit rod 65 and the ball 67 are driven by the pressure of the side wall of the tubular standard part to move the spray head 5 backward, and the spray head 5 passes through the sleeve block. 62 moves backward outside the support 61 and compresses the spring 63. When the spray head 5 moves backward to the position of the trigger switch assembly 10 and the spray assembly 9, the spraying work can be carried out at this time. When the spray head 5 moves horizontally, the limit rod 65 moves along with it, and the ball 67 set at the end of the limit rod 65 contacts the side wall of the tubular standard part. When the limit rod 65 moves along with it, the ball 67 converts the static friction force into the sliding friction force to reduce the friction force when the limit rod 65 contacts the side wall of the tubular standard part, so as to ensure the translation of the limit rod 65 on the tubular standard part.

[0047] When the limiting rod 1 65 and the compensation component 7 are separated from the surface of the tubular standard part, the elastic force of the spring 63 is used to push the sleeve block 62 to move the spray head 5 forward to the initial position to complete the reset, and the limiting rod 1 65 can be rotated to adjust its extended length, thereby changing the distance between the limiting rod 1 65 and the spray head 5, and then adjusting the spraying distance. After the adjustment is completed, the outer wall of the limiting rod 1 65 can be pressed by the telescopic rod 2 66;

[0048] The distance between the limit rod 65 and the spray head 5 is fixed, the limit rod 65 is always in contact with the tubular standard part, and the distance between the spray head 5 and the tubular standard part is always the same. No matter whether the tubular standard part is thick or thin, the limit rod 65 is always in contact with the side wall of the tubular standard part for spraying, so as to ensure the constant spraying distance. By keeping the distance between the spray head 5 and the tubular standard part constant, the equipment can maintain the same spraying distance when spraying tubular standard parts of any thickness, which not only ensures the spraying thickness of the tubular standard parts, but also avoids the problem of frequently adjusting the position of the spray head 5, increasing the workload and time cost of the operator, and reducing the spraying efficiency.

[0049] like Fig. 9 As shown, the switch assembly 10 includes a support column 101 fixed to the front of the sleeve block 62, the support column 101 is located directly below the support column 61, a connecting column 102 is fixed to the back of the support column 61, the connecting column 102 is located directly below the support column 61 and is opposite to the position of the support column 101, a control groove 103 is formed at the end of the connecting column 102 facing the support column 101, the control groove 103 is opposite to the position of the support column 101, and a pressure switch 104 is installed on the inner wall of the control groove 103.

[0050] The pressure switch 104 is electrically connected to the pump body 92. When the spray head 5 moves backward outside the support 61 through the sleeve block 62 and squeezes the spring 63, the sleeve block 62 drives the support column 101 to move into the control groove 103. When the end of the support column 101 contacts and squeezes the pressure switch 104, the pressure switch 104 controls the pump body 92 to start spraying the paint.

[0051] It should be noted here that when the spray head 5 drives the end of the anti-pillar 101 through the sleeve block 62 to move to the position where it just touches the pressure switch 104 and enables the pressure switch 104 to control the pump body 92 to start, the paint inlet 97 is just moved into the paint discharge port 95 to connect the docking joint 96 with the connecting joint 94. It should be noted that the depth of the control groove 103 is shallow, and the limit rod 65 just touches the side wall of the tubular standard part and continues to move a slight distance toward the position of the tubular standard part. The anti-pillar 101 will extend into the control groove 103 and touch the pressure switch 104. The purpose of this design is to prevent the limit rod 65 from exerting too much pressure on the side wall of the tubular standard part, thereby crushing the tubular standard part.

[0052] like Figure 3 As shown, the compensation assembly 7 includes a side block 71 fixed on the other side of the spray head 5, a limiting rod 72 passes through the interior of the side block 71, a ball 74 is embedded in the end of the limiting rod 72 facing the spray chamber 1, and a telescopic rod 73 is installed at the top and bottom ends of the front part of the side block 71.

[0053] When the limiting rod 1 65 contacts the outer surface of the tubular standard part and the spray head 5 is moved backward due to the influence of the side wall of the tubular standard part, the limiting rod 2 72 also moves with it. The limiting rod 1 65 and the limiting rod 2 72 have the same position. When the spray head 5 moves from right to left, the limiting rod 1 65 contacts the side wall of the tubular standard part first, and the ball 2 74 at the end of the limiting rod 2 72 contacts the side wall of the tubular standard part later. When the limiting rod 1 65 moves away from the side wall of the tubular standard part, the limiting rod 2 72 still contacts the side wall of the tubular standard part. At this time, the spray head 5 is affected by the limiting rod 2 72, and the position of the spray head 5 is maintained in the state when it is affected by the limiting rod 1 65. The limiting rod 2 72 prevents the limiting rod 1 65 from moving away from the side wall of the tubular standard part. The spray head 5 that loses the effect of the limiting rod 1 65 cannot maintain a constant distance with the tubular standard part, which affects the spraying.

[0054] It should be noted here that the length of side block 2 71 is a multiple of the length of side block 1 64. The purpose of this design is to ensure the distance between limit rod 1 65 and limit rod 2 72 so that limit rod 2 72 can cooperate with drying component 8 to allow the paint surface to have enough time to solidify before contacting the end face sprayed with paint.

[0055] like Figures 3 to 6 As shown, the drying component 8 includes a support rod 81 arranged on one side of the limit rod 2 72, the support rod 81 is fixed on the side block 2 71, and is located between the spray head 5 and the limit rod 2 72, a groove 82 is opened at one end of the support rod 81 facing the spray chamber 1, and a heating wire 83 is installed in the groove 82, an air inlet pipe 84 is fixed to the side wall of the support rod 81, a connecting pipe 85 is installed on the back of the air inlet pipe 84, and the air inlet pipe 84 is connected to the connecting pipe 85, the drying component 8 also includes an exhaust fan 86 fixed at the front of the side block 2 71, the input end of the exhaust fan 86 is connected to the connecting pipe 85, and the output end of the exhaust fan 86 is installed with an exhaust pipe 87, a purification box 88 is installed at the front of the movable frame 41, the purification box 88 is located below the pump body 92, the input end of one side of the purification box 88 is connected to the exhaust pipe 87, and an activated carbon filter 89 is installed inside the purification box 88.

[0056] Since the limit rod 1 65 contacts the side wall of the tubular standard part first, the position contacted by the limit rod 2 72 is the surface of the tubular standard part after painting. In order to prevent the paint surface from being affected by the limit rod 2 72, the groove 82 is used to dry the surface contacted by the ball 2 74 at the end of the limit rod 2 72 to accelerate the solidification speed of the paint surface. At the same time, the exhaust fan 86 is used to continuously exhaust air through the connecting pipe 85, and the paint surface around the support rod 81 is sucked by the air inlet pipe 84 to accelerate the flow rate of the gas. The drying of the groove 82 is used to improve the solidification effect of the paint surface to prevent the limit rod 2 72 from damaging the integrity of the paint surface when passing through the uncondensed paint surface. Among them, the exhaust fan 86 cooperates with the air inlet pipe 84, the connecting pipe 85 and the exhaust fan 86 to draw the gas generated by the paint spraying into the purification box 88, and the activated carbon filter 89 in the purification box 88 is used to filter and purify the gas, so as to reduce the impact of the gas generated by the paint spraying on the staff and the environment.
