Description

Technical Field

[0001] The utility model belongs to the technical field of paint spraying tools, in particular to a surrounding spraying paint spray gun. Background Art

[0002] Paint spray guns are used for spraying paint, and siphon paint spray guns are widely used because of their low price and ease of use. The siphon paint spray gun includes a spray gun body and a paint storage tank. The spray paint is stored in the paint storage tank. The paint storage tank has a guide pipe, which extends to the bottom of the paint storage tank to absorb the spray paint. The paint storage tank is connected to the feed port of the spray gun body to feed the spray gun body.

[0003] In order to mix the spray paint in the paint storage tank evenly, the operator holds the handle end of the paint spray gun and aims the nozzle at the workpiece for spraying. However, since the storage tank and the handle are connected as one, in order to ensure uniform paint spraying during operation, the operator needs to shake the entire gun body constantly with the hand, which is extremely exhausting for the operator under long-term working conditions. Moreover, the way of shaking the hand back and forth cannot ensure that the paint on the surface of the sprayed workpiece maintains a uniform coating thickness, so it is difficult to ensure the quality of the same batch of sprayed workpieces.

[0004] In addition, the nozzle of the existing spray gun is fixed. When it is necessary to spray the back of wooden furniture and workpieces, the wooden furniture is heavy and difficult to move or turn over, or the spraying position of the painted parts is close to the ground. At this time, it is difficult for the operator to quickly and effectively spray the painted parts with a traditional fixed spray gun, which affects the work quality and work efficiency.

[0007] The beneficial effects of the utility model are as follows: the spray gun hinges and arranges the surrounding component at the front end of the clamping part, and installs the atomizing nozzle on the surrounding component, so that the spraying direction of the atomizing nozzle can be adjusted, thereby increasing the paint spraying direction and flexibility of the spray gun, and being convenient for users to use; a transmission component is arranged in the surrounding component, and the transmission component can drive the atomizing nozzle to swing in a surrounding manner, thereby increasing the coverage range of the paint spraying of the spray gun, making the paint spraying more uniform, and reducing the work intensity of the user; the transmission component of the spray gun is driven by a motor and can operate stably; a slider and a threaded rod that are mutually threadedly driven are combined in the transmission component, so that the radius of the swing trajectory of the atomizing nozzle can be flexibly adjusted to adapt to various usage conditions.

DETAILED DESCRIPTION

[0017] The utility model is now described in further detail with reference to the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0018] A paint spray gun for surround spraying comprises a clamping portion 10, a surround component 30, an atomizing nozzle 50 and a transmission component 60; the atomizing nozzle 50 is rotatably mounted on the front side of the surround component 30, an articulated joint is arranged at the rear of the surround component 30, the surround component 30 is arranged at the front end of the clamping portion 10 through the articulated joint, a knob 20 for locking and loosening the joint is arranged on the articulated joint, the articulated joint can be switched between a rigid connection state and a flexible connection state by tightening and loosening the knob 20 respectively, when the knob 20 is loosened to make the articulated joint flexibly connected, the angle of the surround component 30 on the clamping portion 10 can be adjusted arbitrarily, when the knob 20 is tightened to make the articulated joint rigidly connected, the angle between the surround component 30 and the clamping portion 10 can be fixed.

[0019] When it is necessary to paint the back of wooden furniture and the back and sides of other painted parts, it is inconvenient for the operator to paint them in a standing posture due to the position, weight and specific size of corners of the painted parts such as wooden furniture. The operator can adjust the knob 20 according to the actual working environment during the spraying process. By adjusting the knob 20, the angle of the surround component 30 is changed so that the atomizing nozzle 50 of the device is aimed at the surface to be sprayed of the painted part, thereby facilitating the operator to spray paint on the lower side of furniture such as tables and chairs. The knob 20 can be an ordinary knob that is tightened in a threaded manner.

[0020] The transmission component 60 is arranged inside the surrounding component 30, and the transmission component 60 is connected to the atomizing nozzle 50. The transmission component 60 drives the atomizing nozzle 50 to swing periodically. When spraying paint, the transmission component 60 is started. After the transmission component 60 is started, it drives the surrounding component 30 to rotate periodically in the space. At this time, the atomizing nozzle 50 at one end of the surrounding component 30 is driven to swing periodically, so that the paint sprayed by the atomizing nozzle 50 is in a periodically swinging radial shape, which increases the contact area of ​​the workpiece during spraying, improves the spraying efficiency, and improves the uniformity of the paint spraying on the paint surface.

[0021] The surround component 30 includes a mounting block 31, a ball valve 33, a slide rod 34 and a mounting platform 35; the rear end of the mounting block 31 is mounted on the clamping portion 10 through a hinge joint, a transmission chamber 32 is arranged inside the mounting block 31, and the transmission component 60 is arranged in the transmission chamber 32. The ball valve 33 is rotatably embedded at the center of the front wall of the transmission chamber 32, one end of the ball valve 33 passes through the outside of the mounting block 31 and a mounting platform 35 is arranged, the atomizing nozzle 50 is coaxially rotatably mounted on the front end surface of the mounting platform 35, the slide rod 34 is fixedly arranged on the spherical surface of the ball valve 33 exposed in the transmission chamber 32, and is used to realize transmission connection with the transmission component 60, and the atomizing nozzle 50 is bowl-shaped, and the center of the bowl coincides with the spherical center of the ball valve 33.

[0022] The transmission assembly 60 includes a motor 61 and a bracket 62; the motor 61 is fixedly arranged in the mounting block 31, the driving end of the motor 61 is located in the transmission cavity 32 and is coaxially arranged with the mounting block 31, the bracket 62 is flat and is arranged in the transmission cavity 32, the length direction of the bracket 62 is arranged radially along the transmission cavity 32, one end of the bracket 62 is fixed on the driving end of the motor 61, and the other end of the bracket 62 is suspended and connected to the slide rod 34 for transmission, the motor 61 drives the bracket 62 to rotate, that is, the ball valve 33 is driven to rotate on the mounting block 31 through the slide rod 34.

[0023] The transmission assembly 60 also includes a slider 64 and a transmission block 66; a guide groove 63 is provided on the bracket 62 along the length direction, a slider 64 is slidably arranged in the guide groove 63, a transmission block 66 is rotatably arranged in the middle of the slider 64, a through hole 67 is provided on the transmission block 66, and the slide bar 34 is inserted in the through hole 67, that is, the suspended end of the bracket 62 cooperates with the combined slider 64 and the transmission block 66 to complete the transmission of the slide bar 34.

[0024] A threaded rod 65 is arranged in the guide groove 63 along the length direction, and a threaded transmission is formed between the threaded rod 65 and the slider 64. The position of the slider 64 in the guide groove 63 can be adjusted by twisting the threaded rod 65, and the angle between the slide rod 34 and the rotation axis of the bracket 62 is further adjusted to adjust the swing amplitude of the atomizing nozzle 50 during operation. An operating hole connected to the transmission chamber 32 is opened on the outer wall of the mounting block 31, and a technician can adjust the threaded rod 65 through the operating hole.

[0025] The surround-type spray paint spray gun also includes a paint storage tank 40; the paint storage tank 40 is fixedly arranged on the clamping portion 10, and a feeding pipe 41 is provided on the paint storage tank 40 to realize a feeding connection with the atomizing nozzle 50. The feeding pipe 41 has a restraining force on the atomizing nozzle 50 to ensure that the atomizing nozzle 50 does not rotate with the mounting platform 35. The feeding pipe 41 is provided with a guide pipe inside the paint storage tank 40, and the guide pipe extends to the bottom of the paint storage tank 40. The paint spraying adopts the siphon principle, and the paint in the paint storage tank 40 is fed into the atomizing nozzle 50 through the siphon effect, and is sprayed onto the wooden part through the atomizing nozzle 50.

[0026] It should be noted that one end of the paint storage tank 40 is also connected to a high-pressure air supply device or other air supply device and a connecting port for siphoning the paint in the paint storage tank 40. The connecting port allows high-velocity gas to pass through and generate siphon with the guide tube, thereby pumping the paint into the feeding pipe 41. The siphon device and paint storage tank 40 used in this application can be commonly used siphon pump air devices and storage tanks of common specifications on the market, and this application does not make any specific limitations on this.

[0027] In this device, the atomizing nozzle 50 and the surrounding assembly 30 are connected in a rotating manner. One end of the atomizing nozzle 50 is connected to the paint storage tank 40 through the feeding pipe 41. The transmission assembly 60 drives the surrounding assembly 30 to swing while the surrounding assembly 30 itself is also rotating. Therefore, the atomizing nozzle 50 and the surrounding assembly 30 are connected in a rotating manner, thereby preventing the atomizing nozzle 50 and the feeding pipe 41 from rotating with the surrounding assembly 30 as a whole. When spraying paint, the atomizing nozzle 50 itself will not rotate synchronously with the mounting platform 35 due to the mass of the feeding pipe 41 itself, thereby limiting its unidirectional movement to a fixed angle rotation around the axis of the motor 61. This prevents the feeding pipe 41 from being entangled and knotted.

[0028] Working principle:

[0029] In the present application, the center of the ball valve 33 is colinear with the rotation axis of the bracket 62, the slide rod 34 is slidably inserted in the through hole 67, and the guide groove 63, the slider 64 and the slide rod 34 form a rocker mechanism. At the same time, the slider 64 and the threaded rod 65 are connected by threaded transmission to adjust the position of the slider 64, and the atomizing nozzle 50 is disc-shaped.

[0030] In the initial working state: the axis of the motor 61 is in line with the center of the ball valve 33 and the axis of the atomizing nozzle 50 as shown in the attached figure. Figure 2 As shown, this initial position is a common use scenario, and the use of the spray gun does not enable the transmission assembly 60. At this time, the atomizing nozzle 50 does not produce a circular swing during operation.

[0031] In the surrounding working state: the transmission assembly 60 needs to be activated, and the mounting platform 35 is driven to rotate regularly through the slide rod 34, thereby driving the atomizing nozzle 50 to swing regularly.

[0032] Specifically, the operator rotates and adjusts the threaded rod 65 to make it threadedly transmitted with the slider 64, further realizing the position adjustment of the slider 34, changing the angle between the slider 34 and the rotation axis of the bracket 62, that is, while the position of the ball center of the ball valve 33 remains unchanged, an angle is formed between the axis of the mounting platform 35 and the rotation axis of the bracket 62, that is, the disc-shaped axis of the atomizing nozzle 50 and the rotation axis center of the motor 61 are no longer collinear, and an angle is generated between the two. Figure 7 As shown, at this time, the transmission assembly 60 is running, that is, the motor 61 drives the bracket 62 to rotate, and at this time, the through hole 67 ring drives the slide bar 34 to rotate at a uniform speed. Because the slide bar 34, the ball valve 33 and the mounting platform 35 are connected as a whole, that is, the transmission ball valve 33 drives the mounting platform 35 to rotate in a circular manner, because the atomizing nozzle 50 is restrained by the feeding pipe 41 and will not rotate synchronously with the mounting platform 35, the atomizing nozzle 50 is driven by the mounting platform 35 to perform regular periodic circular swings, and the orbit of the atomizing nozzle 50 is a circle with an adjustable radius.

[0033] When it is necessary to adjust the trajectory radius of the orbiting component 30, the operator rotates the threaded rod 65, and threaded transmission occurs between the threaded rod 65 and the slider 64, thereby driving the slider 64 and the transmission block 66 to slide as a whole along the slotting direction of the guide groove 63. Because the transmission block 66 is rotatably set in the middle of the slider 64, at this time, as the slider 64 moves horizontally, the angle between the axis of the slide rod 34 and the rotation axis of the bracket 62 changes, thereby further changing the radius of the orbiting of the atomizing nozzle 50. By adjusting the orbit radius of the atomizing nozzle 50, the contact surface between the paint and the workpiece during spraying is adjusted.

[0034] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
