Description

Technical Field

[0001] This utility model belongs to the field of spraying technology, and in particular relates to a spraying device for a spraying production line. Background Technology

[0002] A spray coating production line is an automated spray coating production equipment. Its main purpose is to uniformly spray coatings or protective layers onto products. In modern manufacturing, spray coating production lines are widely used in various industries, such as automobile manufacturing, home appliance manufacturing, and building materials manufacturing. A spray coating production line mainly consists of three parts: a conveying system, spray coating equipment, and drying equipment.

[0003] Publication No. CN218308691U discloses a spraying device for a spraying production line. The device uses a moving motor to drive a threaded rod to rotate, which in turn drives the spray head to move left and right under the action of a moving block to spray the workpiece. At the same time, the rotating motor drives the rotating shaft, electric push rod, and workpiece between the clamping plates to rotate together to avoid clamping after rotation. Then, under the power provided by the air pump, the workpiece enters the treatment box with the airflow and is degraded and disinfected by a photocatalytic mesh.

[0004] The aforementioned existing technologies still have the following drawbacks in practical implementation:

[0005] During use, multiple drive mechanisms such as a rotating motor, a moving motor, and an air pump need to be set up. The operation of multiple drive mechanisms requires electricity, which increases the manufacturing and use costs of the device. If one of the drive mechanisms fails, it will seriously affect the smooth progress of the product spraying operation and result in poor performance. At the same time, the paint is prone to settling and sedimentation during the spraying process, which affects the spraying effect.

[0006] To address the above problems, we propose a spraying device for a spraying production line. Utility Model Content

[0009] The exhaust structure includes a bracket, a rotating shaft, a fan, an exhaust pipe, and a purification box. The exhaust pipe is connected to the exhaust port. The bracket is fixed inside the exhaust port. The rotating shaft is rotatably mounted on the bracket. One end of the rotating shaft is fixedly connected to a reciprocating lead screw. The fan is installed at the end of the rotating shaft away from the reciprocating lead screw. The fan cooperates with the inner cavity of the exhaust pipe.

[0010] The purification box is connected to the exhaust pipe. A photocatalytic mesh is installed inside the purification box. An exhaust port is opened on the top of the purification box. Several fluorescent tubes are installed on the top of the inner wall of the purification box. The fluorescent tubes are used in conjunction with the photocatalytic mesh.

[0011] The clamping mechanism includes a support rod, a support tube, a disc, an electric push rod, a left clamping plate, and a right clamping plate. The support rod and the support tube are rotatably mounted on the spray box. The disc is fixed to one of the outer ends of the support tube. The electric push rod is mounted on the disc. The telescopic end of the electric push rod passes through the inner cavity of the support tube and is connected to the left clamping plate. The right clamping plate is fixed to one of the inner ends of the support rod. The transmission assembly is located between the support tube and the reciprocating lead screw.

[0012] The spraying assembly includes a liquid supply pump, a liquid supply pipe, a spray pipe, and a spray head. The liquid supply pump is connected to one side of the supply box via a liquid extraction pipe. One end of the liquid supply pipe is connected to the liquid supply pump, and the other end extends into the spraying box and is connected to the spray pipe. The spray pipe is fixed to the bottom of the movable block by a pipe clamp, and the spray head is installed at the lower end of the spray pipe.

[0013] A guide rod is fixed inside the upper side of the spray box. The guide rod passes through the movable block, and the movable block and the guide rod are slidably engaged.

[0014] The transmission assembly includes pulleys and a transmission belt. The two pulleys are respectively mounted on the reciprocating lead screw and the support tube. The transmission belt is driven between the two pulleys. Two guide plates are fixed at an angle to each other on the lower side of the inner wall of the spray box. A collection box is movably mounted on the lower side of the inside of the spray box. The opening end of the collection box cooperates with the lower end of the guide plate. A door is movably mounted on the front side of the spray box.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention utilizes a clamping mechanism to easily hold and fix the workpiece to be sprayed. The spraying assembly then performs the spraying process on the clamped workpiece. The threaded engagement between the movable block and the reciprocating screw facilitates adjustment of the reciprocating motion of the spraying assembly. Simultaneously, the transmission assembly drives the clamping mechanism to rotate, thereby rotating the clamped workpiece and achieving comprehensive spraying of the workpiece's circumference. This effectively improves the spraying effect and efficiency. Furthermore, the meshing of the first and second bevel gears allows the stirring rod to rotate synchronously during the spraying process, which in turn stirs the paint in the feed box, preventing sedimentation and ensuring a better spraying effect. This solves the problem of sedimentation during spraying, which is a common issue in existing technologies and affects the spraying results.

[0017] Simultaneously, with the rotation of the shaft and the bracket, the reciprocating screw rotates, driving the fan to rotate synchronously. This discharges the harmful gases generated during spraying in the spraying box to the purification box for purification treatment. This eliminates the need for multiple drive mechanisms, solving the problems of existing technologies that require multiple drive mechanisms such as rotating motors, moving motors, and air pumps. The operation of multiple drive mechanisms requires electricity, increasing the manufacturing and operating costs of the device. Furthermore, if one drive mechanism fails, it will seriously affect the smooth progress of product spraying operations and result in poor performance. Attached Figure Description

[0028] This specific embodiment is a spraying device for a spraying production line, such as... Figures 1-9 As shown, the spraying device of the spraying production line includes a spraying box 1, a reciprocating screw 2 rotatably mounted on the spraying box 1, a movable block 3 threaded onto the reciprocating screw 2, a feeding box 4 mounted on one side of the top of the spraying box 1, a spraying assembly between the feeding box 4 and the movable block 3, a stirring rod 5 rotatably mounted inside the feeding box 4, several stirring blades 6 fixed on the stirring rod 5, the lower end of the stirring rod 5 penetrating through the bottom of the feeding box 4 and connected to a second bevel gear 8, a first bevel gear 7 meshing with the lower side of the second bevel gear 8, the first bevel gear 7 being mounted on the reciprocating screw 2, an exhaust port penetrating through the right side of the spraying box 1, an exhaust structure mounted inside the exhaust port, a clamping mechanism mounted on the lower side of the reciprocating screw 2, and a transmission assembly 19 mounted between the clamping mechanism and the reciprocating screw 2.

[0029] The exhaust structure includes a bracket 9, a rotating shaft 10, a fan 11, an exhaust pipe 12, and a purification box 20. The exhaust pipe 12 is connected to the exhaust port. The bracket 9 is fixed inside the exhaust port. The rotating shaft 10 is rotatably mounted on the bracket 9. One end of the rotating shaft 10 is fixedly connected to the reciprocating screw 2. The fan 11 is installed at the end of the rotating shaft 10 away from the reciprocating screw 2. The fan 11 and the inner cavity of the exhaust pipe 12 cooperate with each other.

[0030] The clamping mechanism facilitates the clamping and fixing of the workpiece to be sprayed. The spraying assembly then sprays the clamped workpiece. The threaded engagement between the movable block 3 and the reciprocating screw 2 facilitates the adjustment of the reciprocating motion of the spraying assembly. Simultaneously, under the action of the transmission assembly 19, the clamping mechanism is driven to rotate, thereby driving the clamped workpiece to rotate, achieving the purpose of comprehensive spraying of the workpiece's circumference. This effectively improves the spraying effect and efficiency. The meshing action of the first bevel gear 7 and the second bevel gear 8 facilitates the synchronous rotation of the stirring rod 5 during the spraying operation, thereby driving the stirring blade 6 to stir the paint in the feed box 4. This prevents the paint from settling due to static conditions, which would affect the subsequent spraying effect. This solves the problem of paint settling during the spraying process in the existing technology, which affects the spraying effect.

[0031] Simultaneously, with the rotational cooperation of the rotating shaft 10 and the bracket 9, the reciprocating screw 2 rotates, driving the fan 11 to rotate synchronously, expelling the harmful gases generated in the spraying box 1 to the purification box 20 for purification treatment. This eliminates the need for multiple drive mechanisms, solving the problems of existing technologies that require multiple drive mechanisms such as rotating motors, moving motors, and air pumps during use. Moreover, the operation of multiple drive mechanisms requires electricity, increasing the manufacturing and usage costs of the device. If one of the drive mechanisms fails, it will seriously affect the smooth progress of the product spraying operation and result in poor performance.

[0032] The purification box 20 is connected to the exhaust pipe 12. A photocatalytic mesh 21 is provided inside the purification box 20. An exhaust port is opened on the top of the purification box 20. Several fluorescent tubes 22 are installed on the top of the inner wall of the purification box 20. The fluorescent tubes 22 cooperate with the photocatalytic mesh 21.

[0033] The clamping mechanism includes a support rod 13, a support tube 14, a disc 15, an electric push rod 16, a left clamping plate 17, and a right clamping plate 18. The support rod 13 and the support tube 14 are rotatably mounted on the spray box 1. The disc 15 is fixed to the outer end of the support tube 14. The electric push rod 16 is mounted on the disc 15. The telescopic end of the electric push rod 16 passes through the inner cavity of the support tube 14 and is connected to the left clamping plate 17. The right clamping plate 18 is fixed to the inner end of the support rod 13. The transmission assembly 19 is located between the support tube 14 and the reciprocating lead screw 2.

[0034] The spraying assembly includes a liquid supply pump, a liquid supply pipe 24, a spray pipe 25, and a nozzle 26. The liquid supply pump is connected to one side of the supply box 4 through a liquid extraction pipe. One end of the liquid supply pipe 24 is connected to the liquid supply pump, and the other end extends into the spraying box 1 and is connected to the spray pipe 25. The spray pipe 25 is fixed to the bottom of the movable block 3 by a pipe clamp, and the nozzle 26 is installed at the lower end of the spray pipe 25.

[0035] A guide rod 27 is fixed inside the upper side of the spray box 1. The guide rod 27 passes through the movable block 3, and the movable block 3 is slidably engaged with the guide rod 27. The guide rod 27 facilitates the limiting and guiding of the movable block 3, ensuring the stability of the reciprocating motion of the movable block 3. A servo motor 28 is mounted on the outside of the spray box 1 through a mounting bracket. The output end of the servo motor 28 is connected to the left end of the reciprocating lead screw 2. The stirring rod 5 passes through the mounting bracket, and the stirring rod 5 is rotatably engaged with the mounting bracket.

[0036] The transmission assembly 19 includes pulleys and a transmission belt. The two pulleys are respectively mounted on the reciprocating screw 2 and the support tube 14. The transmission belt is driven between the two pulleys. Two guide plates 30 are fixed at an angle to each other on the lower side of the inner wall of the spray box 1. A collection box 29 is movably mounted on the lower side of the inside of the spray box 1. The opening end of the collection box 29 cooperates with the lower end of the guide plate 30. A door is movably mounted on the front side of the spray box 1.

[0037] Example:

[0038] When in use, first place the workpiece to be sprayed between the left clamping plate 17 and the right clamping plate 18, so that one side of the workpiece is in contact with the right clamping plate 18. At this time, start the electric push rod 16. As the electric push rod 16 extends, it drives the left clamping plate 17 to move closer to the right clamping plate 18, thereby completing the purpose of clamping and fixing the workpiece, and then close the box door.

[0039] Next, the servo motor 28 and the liquid supply pump are started. The liquid supply pump extracts the paint from the supply box 4 and delivers it to the spray pipe 25 through the liquid supply pipe 24. Finally, it is sprayed out through the nozzle 26. At the same time, the servo motor 28 drives the reciprocating screw 2 to rotate. With the threaded engagement between the movable block 3 and the reciprocating screw 2, and the sliding engagement between the movable block 3 and the guide rod 27, the movable block 3 is driven to reciprocate linearly along the direction of the reciprocating screw 2. This drives the spray pipe 25 and the nozzle 26 to reciprocate synchronously, and spray the workpiece that is clamped and fixed.

[0040] Under the action of the transmission component 19, the reciprocating screw 2 rotates, which drives the support tube 14 to rotate. Under the rotational connection between the support rod 13 and the spray box 1, the clamped and fixed workpiece is rotated synchronously, so as to achieve the purpose of spraying the workpiece's circumference and side surface, which effectively improves the spraying efficiency.

[0041] During the rotation of the reciprocating screw 2, the rotating shaft 10 is driven to rotate synchronously, which in turn drives the fan 11 to rotate. The harmful gases generated in the spraying box 1 are discharged to the purification box 20 through the exhaust pipe 12. With the cooperation of the fluorescent tube 22 and the photocatalytic mesh 21, the toxic and harmful gases entering the purification box 20 are degraded and finally discharged through the exhaust port, so as to avoid the toxic and harmful gases generated by the spraying from polluting the workplace.

[0042] During the rotation of the reciprocating screw 2, the first bevel gear 7 is driven to rotate. Under the meshing action of the first bevel gear 7 and the second bevel gear 8, combined with the rotation of the stirring rod 5, the stirring blade 6 is driven to rotate synchronously, so as to achieve the purpose of stirring the paint inside the feed box 4. This solves the problem that the paint is prone to settling and sedimentation during the spraying process in the existing technology, which affects the spraying effect. It avoids the paint settling and sedimentation, which affects the spraying effect. It realizes the flexible adjustment of the spraying surface of the workpiece during the spraying operation, and the emission and purification of toxic and harmful gases generated during the spraying. At the same time, it achieves the purpose of stirring the paint. There is no need to set up multiple drive mechanisms. This solves the problem that the existing technology requires multiple drive mechanisms such as rotating motor, moving motor and air pump during use. Moreover, the operation of multiple drive mechanisms requires electricity, which increases the manufacturing and use cost of the device. If one drive mechanism fails, it will seriously affect the smooth progress of the product spraying operation and the poor use effect.

[0043] During the spraying process, excess paint slides down the inclined surface of the guide plate 30 into the collection box 29 for unified collection and treatment.

[0044] It should be further explained that the installation structure, connection method or setting method of each component in this utility model are all common mechanical methods. As long as they can achieve their beneficial effects, they can be implemented. At the same time, the electric push rod 16, liquid supply pump, photocatalyst net 21, fluorescent tube 22 and servo motor 28 in this utility model are all purchased from the market.
