Description

Technical Field

[0001] The utility model belongs to the technical field of spraying equipment, and in particular relates to a real stone paint spraying device. Background Art

[0002] Real stone paint is a kind of paint with decorative effect similar to marble and granite. It is mainly made of natural stone powder of various colors. It is used for imitation stone effect on building exterior walls, so it is also called liquid stone. Real stone paint needs to be sprayed by a sprayer when in use. The sprayer is a special coating equipment using spraying technology. The principle is to control the airflow to instantly push the air distribution reversing device to reverse, so that the piston of the pneumatic motor can make stable and continuous reciprocating motion, pressurize the inhaled paint, and transport the paint to the spray gun of the sprayer through a high-pressure hose. The spray gun instantly atomizes the paint and releases it to the surface of the object to be painted. The sprayer is mainly composed of a feeding device, a spray gun, and an atomization source.

[0003] When the existing sprayer is in use, when spraying surfaces such as high walls, workers need to climb scaffolding to drive the spray gun to a high place, and the spray gun is connected to the feeding device through a feeding pipe. However, when the workers use the sprayer to spray the wall, they need to move back and forth on the scaffolding to spray the high walls in turn until the feeding pipe is continuously displaced by the workers through the spray gun. If the feeding pipe slides downward under its own weight, and some feeding pipes with real stone paint are heavier, the workers need to manually pull the feeding pipe with great effort, which is not only time-consuming and labor-intensive, but also greatly affects the spraying efficiency of the sprayer. In order to avoid the feeding pipe from slipping during use, we have proposed a real stone paint spraying device. Utility Model Content

It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0030] The utility model embodiment provides a real stone paint spraying device, such as Figure 1-Figure 4 As shown, it includes a spray gun head 1 with an opening and closing valve, and a feeding pipe 3 for conveying real stone paint is installed at one end of the spray gun head 1, characterized in that an anti-skid mechanism 2 is provided on the outer wall of the feeding pipe 3, and the anti-skid mechanism 2 is used to fix and limit the outer wall of one end of the feeding pipe 3;

[0031] The anti-slip mechanism 2 includes: a clamping assembly, a limiting assembly, and a limiting ring 206;

[0032] There are multiple limit rings 206, and the multiple limit rings 206 are equidistantly formed on the outer wall of the feeding tube 3;

[0033] The locking assembly implemented from the open state to the closed state is used to drive the limit assembly to change from the open state to the closed state synchronously;

[0034] The clamping assembly in the closed state limits the two ends of the limiting ring 206 protruding from the outer wall of the feeding tube 3 to prevent the feeding tube 3 from moving downward;

[0035] The limit assembly in the closed state is sleeved on the connection node of the scaffold to prevent the locking assembly from moving downward in the vertical direction.

[0036] In this embodiment, when using the device, a feeding pipe 3 that is sufficient for a worker to drive the spray gun head 1 to move back and forth on the scaffold is placed on the scaffold, and then the steel pipe on the scaffold is sleeved by the limit assembly, and the limit at the cross-shaped steel pipe connection node on the scaffold can prevent the limit assembly from being separated from the scaffold during subsequent use;

[0037] Afterwards, a limiting ring 206 on the outer wall of the feeding tube 3 is sleeved and limited by the clamping assembly, and in this process, the limiting assembly cooperates with the clamping assembly to limit and fix the feeding tube 3 by a limiting ring 206, and the limiting assembly is fixed and locked, so as to prevent the feeding tube 3 from falling down along the outer wall of the scaffold during subsequent use, causing the worker to pull it manually;

[0038] Afterwards, the sprayer can transport the real stone paint to the inner cavity of the spray gun head 1 through the feeding pipe 3, and spray the real stone paint at the designated position through the nozzle of the spray gun head 1 to form a coating layer. During this process, the worker can drive the spray gun head 1 to move back and forth on the scaffolding, and by stacking the feeding pipes 3 on the scaffolding, it is avoided that the worker needs to pull the feeding pipes 3 during the movement.

[0039] In a further preferred embodiment of the present invention, Figure 2-Figure 4 As shown, the snap-fit ​​assembly includes:

[0040] A fixed seat 202 is arranged on the outer wall of the feeding tube 3 and is connected to a limit ring 206. The top of the fixed seat 202 is rotatably connected to a connecting rotating plate 203 through a connecting shaft. Two torsion springs 205 sleeved on the outer wall of the connecting shaft are symmetrically arranged inside one end of the connecting rotating plate 203. The two ends of the torsion spring 205 are respectively engaged with the inner wall of the connecting rotating plate 203 and the outer wall of the fixed seat 202. The inner wall of the connecting rotating plate 203 and the outer wall of the fixed seat 202 are both formed with holes for inserting the ends of the torsion spring 205. The connecting rotating plate 203 is used to squeeze and position the outer wall of the limit ring 206.

[0041] The top end of the connecting rotating plate 203 away from the torsion spring 205 is engaged with a positioning block 201, and the bottom end of the positioning block 201 is formed with a rotating flap 204 that penetrates to the outside of the bottom end of the connecting rotating plate 203. The rotating flap 204 is rotatably connected to the fixing seat 202 through a rotating shaft and a rotating groove. The positioning block 201 and the rotating flap 204 are used to engage and fix the connecting rotating plate 203;

[0042] The limiter components include:

[0043] A rotating sleeve 2011 is rotatably connected to one end of the fixed seat 202 through a hinge, and a movable pressure plate 2010 slidably connected to the fixed seat 202 is formed on the top of the rotating sleeve 2011. A lifting card plate 208 that is engaged with the movable pressure plate 2010 is slidably connected inside one end of the fixed seat 202, and two limit sliders 209 are symmetrically formed at both ends of the lifting card plate 208. The upper and lower ends of the lifting card plate 208 are both semicircular, and one end of the rotating flap 204 is formed with a limit pressure plate 207 for squeezing and limiting the lifting card plate 208. A positioning slot for the movable pressure plate 2010 to be engaged is provided on the movable pressure plate 2010, and a connecting rotating groove for the rotating flap 204 and the limit pressure plate 207 to rotate is provided on the fixed seat 202. A limit sliding groove for the lifting card plate 208 and the limit slider 209 to be lifted and lowered is provided at the connection position of the fixed seat 202 and the lifting card plate 208 and the limit slider 209.

[0044] In this embodiment, a feeding tube 3 that is large enough to reciprocate on the scaffold is placed on the scaffold, and then the fixed seat 202 is sleeved on the steel pipe of the scaffold, and the rotating sleeve 2011 is rotated by the hinge. At this time, the movable pressing plate 2010 is driven by the rotating sleeve 2011 to squeeze the lifting card plate 208. At the same time, the lifting card plate 208 is squeezed by the movable pressing plate 2010 and drives the limit slider 209 to rise along the inner wall of the fixed seat 202, so that the fixed seat 202 cooperates with the rotating sleeve 2011 to sleeve the outer wall of the steel pipe. At this time, the restriction at the cross-shaped steel pipe connection node on the scaffold can prevent the fixed seat 202 and the movable pressing plate 2010 from being separated from the scaffold during subsequent use.

[0045] After that, a limiting ring 206 on the outer wall of the feeding tube 3 is inserted into the positioning groove at the top of the fixing seat 202, and then the connecting rotating plate 203 is rotated with the connecting shaft as the axis to squeeze the top of a limiting ring 206. At the same time, the connecting rotating plate 203 twists the two limiting rings 206 by rotating, so that the feeding tube 3 can be conveniently positioned by a limiting ring 206. Then, the rotating flap 204 is driven to slide and connect with the connecting rotating plate 203 with the rotating shaft as the axis. At this time, the limiting pressing plate 207 squeezes the lifting card under the drive of the rotating flap 204. The plate 208 descends and is inserted into the interior of the movable pressure plate 2010. At the same time, the positioning block 201 is moved to the top of the connecting rotating plate 203 under the drive of the rotating flap 204, and then the connecting rotating plate 203 is released. At this time, the torsion spring 205 drives the connecting rotating plate 203 to engage with the positioning block 201 through torsion rebound, so that the connecting rotating plate 203 and the rotating flap 204 can be fixed synchronously to prevent the feeding pipe 3 from falling down along the outer wall of the scaffold during subsequent use, causing the workers to pull it manually.

[0046] In a further preferred embodiment of the present invention, Figure 2-Figure 4 As shown, a positioning groove that matches the outer wall of the limiting ring 206 is opened at the connecting position of the fixing seat 202, the connecting rotating plate 203 and the limiting ring 206, and a rubber pad is provided on the inner wall of the positioning groove on the connecting rotating plate 203.

[0047] In this embodiment, the friction force between the connecting rotating plate 203 and the limiting ring 206 can be effectively increased by the cooperation between the positioning groove and the rubber pad.

[0048] The working principle of the utility model is as follows: when using the device, a feeding tube 3 that is sufficient for a worker to drive the spray gun head 1 to move back and forth on the scaffold is placed on the scaffold, and then the fixed seat 202 is sleeved on the steel pipe of the scaffold, and the rotating sleeve plate 2011 is rotated by the hinge. At this time, the movable pressing plate 2010 is driven by the rotating sleeve plate 2011 to squeeze the lifting card plate 208, and the lifting card plate 208 is squeezed by the movable pressing plate 2010, and drives the limit slider 209 to rise along the inner wall of the fixed seat 202, so that the fixed seat 202 cooperates with the rotating sleeve plate 2011 to sleeve the outer wall of the steel pipe. At this time, the restriction at the cross-shaped steel pipe connection node on the scaffold can prevent the fixed seat 202 and the movable pressing plate 2010 from being separated from the scaffold during subsequent use;

[0049] After that, a limiting ring 206 on the outer wall of the feeding tube 3 is inserted into the positioning groove at the top of the fixing seat 202, and then the connecting rotating plate 203 is rotated with the connecting shaft as the axis to squeeze the top of a limiting ring 206. At the same time, the connecting rotating plate 203 twists the two limiting rings 206 by rotating, so that the feeding tube 3 can be conveniently positioned by a limiting ring 206. Then, the rotating flap 204 is driven to slide and connect with the connecting rotating plate 203 with the rotating shaft as the axis. At this time, the limiting pressing plate 207 squeezes the lifting card under the drive of the rotating flap 204. The plate 208 is lowered and inserted into the inside of the movable pressing plate 2010. At the same time, the positioning block 201 is driven by the rotating flap 204 to move to the top of the connecting rotating plate 203, and then the connecting rotating plate 203 is released. At this time, the torsion spring 205 drives the connecting rotating plate 203 to engage with the positioning block 201 through torsion rebound, so that the connecting rotating plate 203 and the rotating flap 204 can be fixed synchronously, so as to prevent the feeding pipe 3 from falling down along the outer wall of the scaffold during subsequent use, causing the worker to pull it manually;

[0050] Special explanation is required: the end of the feed pipe 3 away from the spray gun head 1 is connected to a sprayer for conveying real stone paint, and the main working part of the sprayer is a double-acting pneumatic hydraulic booster pump, and the reversing mechanism is a special form of pilot-type fully pneumatically controlled gas distribution reversing device. After the compressed air enters, when the piston moves to the upper end or lower end of the cylinder, the upper pilot valve or the lower pilot valve is actuated, and the airflow is controlled to instantly push the gas distribution reversing device to reverse, so that the piston of the pneumatic motor performs a stable and continuous reciprocating motion. Since the piston is rigidly connected to the plunger in the paint plunger pump, and the area of ​​the piston is larger than that of the plunger, the inhaled paint is pressurized, and the pressurized paint is conveyed to the spray gun head 1 through a high-pressure hose, and finally the hydraulic pressure is released at the nozzle of the spray gun head 1, and it is instantly atomized and sprayed onto the surface of the coated object to form a coating layer;

[0051] Afterwards, the sprayer can transport the real stone paint to the inner cavity of the spray gun head 1 through the feeding pipe 3, and spray the real stone paint at the designated position through the nozzle of the spray gun head 1 to form a coating layer. During this process, the worker can drive the spray gun head 1 to move back and forth on the scaffolding, and by stacking the feeding pipes 3 on the scaffolding, it is avoided that the worker needs to pull the feeding pipes 3 during the movement.
