Description

Technical Field

[0001] This utility model relates to the field of electrostatic rotary cup technology, and in particular to an electrostatic rotary cup that can be used for both cup and gun. Background Technology

[0002] In the field of modern industrial spraying, electrostatic rotary cup spraying and spray gun spraying are two widely used spraying methods. Electrostatic rotary cup spraying uses the centrifugal force generated by high-speed rotation to atomize and charge the paint, which can achieve efficient and uniform large-area spraying and is suitable for painting automobile bodies, large metal components, etc. Spray gun spraying uses compressed air to blow and spray the paint, which has the characteristics of flexible operation and precise control of the spraying area. It is often used for local spraying of complex shaped workpieces and fine pattern drawing.

[0003] However, most of the spraying equipment on the market is single-function, either only having electrostatic rotary cup spraying or only being able to use spray guns. When enterprises need to perform diversified spraying operations on different types of workpieces, they need to equip themselves with multiple spraying equipment with different functions. This not only increases the equipment purchase cost, but also occupies a lot of production space. Furthermore, frequent equipment replacement will lead to low production efficiency and increased operating costs.

[0004] In addition, some existing spraying equipment has insufficient stability in its structural design. The transmission components are prone to vibration and noise after long-term operation, which affects the spraying accuracy and equipment lifespan. The equipment is also relatively inconvenient to maintain, and the maintenance of key internal components is difficult, resulting in long downtime and further reducing production efficiency.

[0005] Therefore, how to provide an electrostatic rotating cup that can be used for both cup and gun is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] One objective of this invention is to propose a dual-purpose electrostatic rotary cup sprayer. This invention integrates electrostatic rotary cup spraying and spray gun spraying functions into one unit through a unique dual-degree-of-freedom rotational structure, solving the problems of existing spraying equipment having single functions, requiring frequent equipment replacement, resulting in low efficiency and increased costs.

[0007] A dual-purpose electrostatic rotary cup and spray gun according to an embodiment of the present invention includes a base, a movable seat, and a double-headed cup body. The movable seat is rotatably mounted on the top of the base, and a rotating shaft seat is fixedly mounted in the center of the top of the movable seat. A connecting seat is provided at the bottom of the double-headed cup body, and the connecting seat is movably mounted in the rotating shaft seat via a rotating shaft. A rotary cup head and a spray gun head are respectively mounted on both sides of the double-headed cup body. A servo motor is embedded in one side of the top of the movable seat. A worm gear is connected to the outer wall of the rotating shaft seat and to the rotating shaft for transmission. A worm is mounted on the top output shaft of the servo motor, and the worm gear and the worm wheel mesh with each other to form a transmission pair.

[0008] Furthermore, the top two sides of the double-headed cup body, respectively near the rotating cup head and the spray gun head, are provided with corresponding inlets and air inlets.

[0009] Furthermore, the top of the worm gear is movably connected to the rotating shaft seat via a bearing.

[0010] Furthermore, a motor is centrally installed inside the base, and a connecting groove is provided at the center of the bottom of the movable seat. The motor is connected to the movable seat by inserting its top rotating shaft into the connecting groove.

[0011] Furthermore, the top of the base is integrally formed with an annular block, and the bottom of the movable seat is surrounded by an annular groove, in which the annular block is slidably installed.

[0012] Furthermore, a slot is provided at the bottom of the base, and an inspection cover is engaged in the slot.

[0013] Furthermore, the bottom of the base is integrally formed with a mounting base, and the mounting base has mounting holes circumferentially formed inside.

[0014] Furthermore, cylindrical mounting cavities are respectively opened on both sides of the double-headed cup body. The connecting ends of the rotating cup head and the spray gun head are provided with connecting bosses that are adapted to the mounting cavities. The outer circumference of the connecting bosses is provided with external threads, and the inner wall of the mounting cavity is provided with corresponding internal threads. The rotating cup head and the spray gun head are fixed to both sides of the double-headed cup body by threaded connection.

[0015] Furthermore, the spray gun head connecting boss has an axially extending air intake channel and an oil intake channel inside. One end of the air intake channel is connected to the air cavity inside the spray gun head, and the other end is connected to the air intake port at the top of the double-headed cup body through a radially opened connecting hole. One end of the oil intake channel is connected to the oil cavity inside the spray gun head, and the other end is connected to another oil intake port at the top of the double-headed cup body through another radial connecting hole.

[0016] Furthermore, the connecting ends of the rotary cup head and the spray gun head to the double-headed cup body are provided with positioning pins, and the inner wall of the mounting cavity of the double-headed cup body is provided with positioning pin holes at corresponding positions. The positioning pins and positioning pin holes cooperate to ensure the installation angle accuracy of the rotary cup head and the spray gun head.

[0017] The beneficial effects of this utility model are:

[0018] 1. This utility model integrates the rotary cup head and spray gun head on both sides of the double-headed cup body. Through a dual-degree-of-freedom structure—driven by a base motor to rotate the movable seat horizontally and by a servo motor to rotate the double-headed cup body vertically—it achieves flexible switching between two spraying modes in the horizontal and vertical directions. Compared to traditional single-function spraying equipment, it eliminates the need for frequent equipment or component replacements, significantly improving spraying efficiency, reducing equipment downtime, and effectively lowering enterprise equipment procurement and operating costs.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0030] like Figure 1-4 As shown, this utility model discloses a dual-purpose electrostatic rotating cup and spray gun, comprising: a base 1, a movable seat 2, and a double-headed cup body 3. The movable seat 2 is rotatably mounted on the top of the base 1. A rotating shaft seat 7 is fixedly mounted in the center of the top of the movable seat 2. A connecting seat 8 is provided at the bottom of the double-headed cup body 3. The connecting seat 8 is movably mounted in the rotating shaft seat 7 via a rotating shaft. A rotating cup head 20 and a spray gun head 4 are respectively mounted on both sides of the double-headed cup body 3. A servo motor 10 is embedded in one side of the top of the movable seat 2. A worm gear 9 is connected to the outer wall of the rotating shaft seat 7 and is driven by the rotating shaft. A worm 11 is mounted on the top output shaft of the servo motor 10. The worm 11 and the worm gear 9 mesh with each other to form a transmission pair.

[0031] The working principle of the electrostatic rotary cup / gun dual-purpose device is as follows: The motor 14 inside the base 1 drives the movable seat 2 to rotate around a vertical axis, achieving horizontal angle adjustment of the rotary cup head 20 and the spray gun head 4; the servo motor 10 drives the transmission pair composed of the worm gear 11 and worm wheel 9, causing the double-headed cup body 3 to rotate around a horizontal axis, achieving vertical switching between the rotary cup head 20 and the spray gun head 4. This dual-degree-of-freedom rotary structure design allows the device to flexibly switch working modes in different spraying scenarios, improving spraying efficiency and adaptability.

[0032] The double-headed cup body 3 has corresponding oil inlets 5 and air inlets 6 on both sides of its top, near the rotary cup head 20 and the spray gun head 4, respectively. When using the rotary cup head 20, the paint enters through the oil inlet 5, atomizes and becomes charged under the centrifugal force generated by high-speed rotation, forming uniform paint particles. When using the spray gun head 4, the paint and compressed air enter the spray gun head 4 through the oil inlet 5 and the air inlet 6, respectively, and the compressed air blows the paint apart and sprays it onto the workpiece surface. This design allows the same device to achieve two different spraying methods to meet different coating needs.

[0033] The top of the worm gear 11 is movably connected to the rotating shaft seat 7 via a bearing. This structural design enhances the stability of the worm gear 11, ensures the smoothness and reliability of the transmission process, reduces vibration and noise, and improves the service life and working accuracy of the entire device.

[0034] A motor 14 is centrally mounted inside the base 1, and a connecting groove 16 is provided at the center of the bottom of the movable seat 2. The motor 14 is connected to the movable seat 2 via a top rotating shaft inserted into the connecting groove 16. This connection method allows the movable seat 2 to rotate smoothly under the drive of the motor 14, and facilitates disassembly and maintenance, reducing equipment maintenance costs.

[0035] The base 1 has an integrally formed annular block 15 on its top, and the movable seat 2 has an annular groove 17 around its bottom, with the annular block 15 slidably installed within the annular groove 17. This structural design not only provides additional support for the movable seat 2, ensuring its stability during rotation, but also effectively prevents external dust and debris from entering the interior of the base 1, protecting critical components such as the motor 14 from contamination.

[0036] The base 1 has a slot 18 at its bottom, and a maintenance cover 19 is engaged in the slot 18. When it is necessary to inspect or maintain the motor 14 and other components inside the base 1, simply open the maintenance cover 19. The operation is simple and convenient, reducing equipment downtime.

[0037] The base 1 has an integrally formed mounting base 12 at its bottom, and mounting holes 13 are formed around the mounting base 12. Through the mounting base 12 and the mounting holes 13, the electrostatic rotary cup that can be used for both cup and gun can be conveniently installed on a spraying robot or other spraying equipment to realize automated spraying operations.

[0038] The double-headed cup body 3 has cylindrical mounting cavities on both sides. The connecting ends of the rotary cup head 20 and the spray gun head 4 are each provided with a connecting boss that matches the mounting cavity. The outer circumference of the connecting boss is provided with external threads, and the inner wall of the mounting cavity is correspondingly provided with internal threads. The rotary cup head 20 and the spray gun head 4 are fixed to both sides of the double-headed cup body 3 via threaded connection. This detachable connection method makes replacing the rotary cup head 20 and the spray gun head 4 simple and quick. Users can change to the appropriate spray head at any time according to different spraying needs, improving the versatility and flexibility of the equipment.

[0039] The spray gun head 4 has an axially extending air inlet channel and an oil inlet channel inside its connecting boss. One end of the air inlet channel communicates with the air cavity inside the spray gun head 4, and the other end communicates with the air inlet 6 at the top of the double-headed cup body 3 through a radially opened connecting hole. One end of the oil inlet channel communicates with the oil cavity inside the spray gun head 4, and the other end communicates with another oil inlet 5 at the top of the double-headed cup body 3 through another radially opened connecting hole. This channel design ensures that paint and compressed air can smoothly enter the spray gun head 4, guaranteeing the stability and consistency of the spraying process.

[0040] The connecting ends of the rotary cup head 20 and the spray gun head 4 to the double-headed cup body 3 are each equipped with a positioning pin. Correspondingly, positioning pin holes are provided on the inner wall of the mounting cavity of the double-headed cup body 3. The positioning pins and positioning pin holes cooperate to ensure the installation angle accuracy of the rotary cup head 20 and the spray gun head 4. The cooperation between the positioning pins and positioning pin holes ensures the accuracy of the angle after the rotary cup head 20 and the spray gun head 4 are installed, thereby guaranteeing the stability and consistency of the spraying effect.

[0041] As an example of this application, the servo motor 10 can be a stepper motor or a servo drive motor, which has the characteristics of high precision and high stability, and can accurately control the rotation angle of the double-headed cup 3 to meet the requirements of different spraying processes.

[0042] As an example of this application, the materials of the rotary cup head 20 and the spray gun head 4 can be corrosion-resistant materials such as stainless steel or aluminum alloy to improve their service life and corrosion resistance, and adapt to different spraying environments.

[0043] As an example of this application, the surfaces of the base 1 and the movable seat 2 may be anodized or coated with an anti-corrosion coating to enhance their corrosion resistance and extend the service life of the equipment.

[0044] As an example of this application, the mounting hole 13 of the mounting base 12 can be designed as an oblong hole to allow for fine-tuning during installation, thereby improving the accuracy and convenience of installation.

[0045] In the example of this application, the electrostatic rotary cup that can be used for both coating and spray gun applications can precisely control the operation of the servo motor 10 and the internal motor 14 of the base 1 through the control system, thereby achieving automatic switching and angle adjustment of the rotary cup head 20 and the spray gun head 4, improving coating efficiency and quality. Simultaneously, this device can also be used in conjunction with a coating robot or other automated equipment to achieve a fully automated coating process.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
