Description

Technical Field

[0001] The utility model relates to a spraying device, in particular to a paint spraying device capable of displaying a spraying range. Background Art

[0002] Spraying operations are often involved in engineering projects. At present, most spraying devices on the market are bulky and expensive, and the spraying area when the paint comes out of the spray gun during operation is not intuitive. There is a lack of reminder and indication for the spraying range, and it often requires operators to use it multiple times to control and adjust based on experience and familiarity. When only small-area spraying is required, or when high requirements are placed on the spraying shape, such as artistic patterns in construction, etc., it is easy for the staff to fail to achieve the ideal spraying effect. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a paint spraying device capable of displaying a spraying range, with an indication function, which can ensure the high efficiency of spraying operations.

[0004] To solve the above technical problem, the technical solution adopted by the utility model is:

[0005] A paint spraying device capable of displaying a spraying range includes a spraying body, and a light source assembly is installed at one end of the spraying body close to the nozzle; the light source assembly includes a fixed ring fixed on the spraying body, a sliding ring is arranged on one side of the fixed ring and is tightened by a screw; a plurality of first connecting rods are hinged on the fixed ring, a plurality of second connecting rods are hinged on the sliding ring, each second connecting rod corresponds to a first connecting rod in position, a light source is installed at the end of each second connecting rod, and a point of each second connecting rod between the light source and the sliding ring is hinged to the first connecting rod.

[0006] The light source is an infrared laser lamp.

[0007] The utility model provides a paint spraying device capable of displaying a spraying range, which has the following technical effects:

[0008] 1). An aperture is formed by the light source, and this aperture is matched with the spraying area. In this way, before spraying, the place to be sprayed is irradiated by the aperture, and the coating area after spraying is the range circled by the aperture. In this way, the light source can play an indicating role, making the maximum spraying range clear, providing reference and hint for the staff to accurately spray at a fixed point, ensuring more accurate spraying, and also reducing paint waste to a certain extent.

[0009] 2). By moving the sliding ring, the position of the light source can be adjusted, and thus the size of the aperture can be adjusted. In this way, it can be reasonably adjusted according to the specific spraying range and area to meet different usage requirements. Description of the Drawings

[0016] In the figure: paint box 1, feed pipe 2, filtering device 3, spraying main body 4, nozzle 5, light source assembly 6, electric wire 7, air inlet pipe 8, joint 9, air blowing gun 10, air blowing switch 11, air inlet 12, fixing ring 6.1, sliding ring 6.2, screw rod 6.3, first connecting rod 6.4, second connecting rod 6.5, light source 6.6. Specific embodiments

[0017] As Figures 1-5 shown, a paint spraying device capable of displaying the spraying range includes a spraying main body 4, and a light source assembly 6 is installed at one end of the spraying main body 4 close to the nozzle 5. The light source assembly 6 includes a fixing ring 6.1, and the fixing ring 6.1 can be fixed on the spraying main body 4 by welding or screw connection. A sliding ring 6.2 is provided on the side of the fixing ring 6.1 away from the nozzle 5, and the sliding ring 6.2 can slide along the length direction of the outer wall of the spraying main body 4. A threaded hole is opened radially on the sliding ring 6.2, and the screw rod 6.3 is screwed into the threaded hole and abuts against the outer wall of the spraying main body 4 to achieve locking. A plurality of first connecting rods 6.4 are hinged on the fixing ring 6.1, and a plurality of second connecting rods 6.5 are hinged on the sliding ring 6.2. The position and quantity of each second connecting rod 6.5 correspond to those of the first connecting rod 6.4. A light source 6.6 is installed at the end of each second connecting rod 6.5, and a point of each second connecting rod 6.5 between the light source 6.6 and the sliding ring 6.2 is hinged to the first connecting rod 6.4.

[0018] When the angle of the light source 6.6 needs to be adjusted, the screw rod 6.3 can be unscrewed, the sliding ring 6.2 can be slid back and forth, and the screw rod 6.3 can be locked after adjusting to the specified position. During the sliding process of the sliding ring 6.2, the first connecting rod 6.4 is driven to rotate by the second connecting rod 6.5, and then the rotation angles of the second connecting rod 6.5 and the first connecting rod 6.4 are adjusted, so as to adjust the opening angle of the light source 6.6 in a circle.

[0019] The light source 6.6 is an infrared laser lamp. The infrared laser lamp has good directivity and high brightness, and can also be used as a simple light source to illuminate in the case of insufficient ambient brightness.

[0020] The spraying main body 4 here uses an existing conventional and relatively lightweight spraying device, such as a W-101 manual high-atomization paint spray gun. The lower end of the spraying main body 4 extends into the paint box 1 through the feeding pipe 2, and the paint box 1 contains the stirred paint. The tail of the spraying main body 4 is connected to the air blowing gun 10 through the joint 9. The air blowing gun 10 is provided with an air blowing switch 11, and the tail of the air blowing gun 10 is connected to an external air source through the air inlet 12 for supplying air. And a light source 6.6 is installed near the nozzle 5 at the head of the spraying main body 4, and the light source 6.6 is electrically connected to an external power source or battery through the wire 7.

[0021] Preferably, a filter screen 3 is installed at the connection between the upper end of the feeding pipe 2 and the spraying main body 4.

[0022] The filter screen 3 plays a filtering role.

[0023] Working principle and process: Since the light source 6.6 is arranged in a circle around the nozzle 5, after the light source 6.6 irradiates on the building, an aperture with an area of S is formed, as Figure 5 shown. By controlling the air intake rate through the air blowing switch 11, the area S1 sprayed by the nozzle 5 is adjusted, and S1 ≤ S; this can provide reference and prompt for the spraying range of the staff. Especially when spraying artistic patterns, the nozzle 5 of the spraying main body 4 is aligned with the position to be sprayed, and the sprayable area range can be directly marked through the aperture, and then spraying can be carried out to achieve precise spraying.
