Description

Technical Field

[0001] This utility model relates to the field of spray gun technology for coating equipment, and in particular to a spray gun for coating equipment. Background Technology

[0002] Early spray guns were relatively simple, dating back to air spray guns of the 1920s, primarily used for applying fast-drying coatings such as nitrocellulose lacquer. These early spray guns had relatively crude construction and limited functionality, merely atomizing and spraying paint onto the surface of objects. With industrial development and increasing demands for coating quality and efficiency, spray gun technology further evolved, leading to the emergence of new types such as electrostatic spray guns. Electrostatic spray guns utilize electrostatic fields to effectively adhere paint to the surface of the object being coated, significantly improving paint utilization and coating quality. In recent years, spray gun technology has rapidly progressed towards intelligent and automated applications. Intelligent equipment such as the Yudong Smart600 spray gun system has emerged; these systems feature intelligent remote control and programmable settings, automatically adjusting spraying parameters according to different workpieces and coating requirements to achieve personalized, efficient, and environmentally friendly coating.

[0003] Chinese patent application CN201922016055.2 discloses a spray gun for use in coating production line equipment. The key technical points are: the discharge port on the nozzle of this utility model is designed to be parallel to the wind deflector on the wind cap, which ensures good spraying effect. The spray gun body is equipped with a paint pressure adjustment knob, a spray width adjustment knob, and a paint flow adjustment knob, which can adjust the spray flow rate of the spray gun at any time. The gun head is equipped with a needle to avoid clogging.

[0004] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: the complicated operation of workers installing paint pipes results in a lot of time being spent assembling the fixing pipe and paint pipe, which in turn leads to the overall project progress being delayed. The complicated installation operation requires workers to maintain a specific posture for a long time, which can easily cause physical fatigue and discomfort to the workers. Therefore, in order to solve the above problems, a spray gun for coating equipment is proposed. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of the complex operation of the paint pipe installation by the workers in the existing technology, which leads to the need to spend a lot of time assembling the fixing pipe and the paint pipe, resulting in the overall project progress being delayed. The complex installation operation requires the workers to maintain a specific posture for a long time, which easily causes physical fatigue and physical discomfort to the workers. Therefore, a spray gun for coating equipment is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a spray gun for coating equipment, including a handle, one end of which is provided with an installation device, the installation device including a fixing tube, the fixing tube being fixedly connected to one end of the handle, a paint tube being slidably connected to the arc surface of the fixing tube, a spray head being fixedly connected to one end of the handle, two mounting grooves being formed on the arc surface of the fixing tube, a first spring being fixedly connected to the inner surface of the mounting groove, a blocking block being fixedly connected to the other end of the first spring, two threaded rods being threadedly inserted into the arc surface of the paint tube, a round block being fixedly connected to one end of the threaded rods, and two round grooves being formed on the inner surface of the fixing tube.

[0007] The effect achieved by the above components is as follows: by setting up the installation device, it makes it easier for workers to install the fixed pipe and the paint pipe, avoiding the complicated operation of workers when installing the paint pipe. This avoids the fact that the fixed pipe and the paint pipe need to spend a lot of time assembling, which will lead to the overall project progress being delayed. The complicated installation operation requires workers to maintain a specific posture for a long time, which can easily cause physical fatigue and physical discomfort to workers, and at the same time reduce the enthusiasm of employees.

[0008] Preferably, one end of the fixing tube is slidably connected to a leak-proof pad, the size of which is adapted to the size of the fixing tube.

[0009] The effect achieved by the above components is to enhance the sealing between the fixed pipe and the paint pipe in the pipeline system for conveying paint, thereby preventing paint leakage.

[0010] Preferably, a round rod is slidably connected to the inner surface of the circular groove, a movable frame is slidably connected to the arc surfaces of the two round rods, a handle is fixedly connected to the arc surfaces of the round rods, and a second spring is fixedly connected to one end of the two round rods that is close to each other.

[0011] The effect achieved by the above components is to limit the leak-proof pad and prevent it from falling off after it is installed.

[0012] Preferably, a baffle is fixedly connected to the arc surface of the threaded rod, and one side of the baffle abuts against the fixed tube.

[0013] The effect achieved by the above components is as follows: by setting up a baffle, when one side of the baffle abuts against the arc surface of the fixed pipe, the top of the blocking block is exactly flush with one side of the arc surface of the fixed pipe, which makes it easier for workers to disassemble the paint pipe and prevents the threaded rod from rotating too much and being inserted into the installation groove, which is not conducive to the operation of workers.

[0014] Preferably, the arc surface of the handle is covered with absorbent rubber, which is made of rubber.

[0015] The effect achieved by the above-mentioned components is that when the worker's palms are sweaty, the absorbent rubber absorbs the sweat from their hands, preventing them from slipping.

[0016] Preferably, the arc surface of the nozzle is provided with a protective device, the protective device including a protective cover, the protective cover being slidably connected to the arc surface of the nozzle, the arc surface of the protective cover having two circular holes, the arc surface of the nozzle having two placement grooves, the inner surface of the placement groove being fixedly connected to a third spring, and the other end of the third spring being fixedly connected to a limit rod.

[0017] The effect achieved by the above-mentioned components is as follows: by setting up protective devices, the staff can be prevented from being contaminated when the nozzle is not in use, and the pipes inside the nozzle are prevented from being blocked by contamination. When the nozzle is not in use, it is exposed to the air and is easily attacked by dust, stains and other pollutants. Over time, the internal pipes and other key components of the nozzle may suffer from performance degradation or even damage due to contamination.

[0018] Preferably, a screw is threaded into the inner surface of the circular hole, and a rotating block is fixedly connected to one end of the screw.

[0019] The effect achieved by the above components is that when it is necessary to remove the protective cover, the screw is turned until the limit rod disengages from the threaded hole of the protective cover, and the protective cover is directly removed from the surface of the nozzle.

[0020] In summary, the beneficial effects of this utility model are as follows:

[0021] 1. In this utility model, by setting up an installation device, the installation of the fixing pipe and the paint pipe can be made easier for the staff to install. This avoids the complicated operation of the paint pipe installation, which would otherwise require a lot of time to assemble the fixing pipe and the paint pipe, thus causing the overall project progress to be delayed. The complicated installation operation requires the staff to maintain a specific posture for a long time, which can easily cause physical fatigue and discomfort to the staff, and also reduce the staff's work enthusiasm.

[0022] 2. In this utility model, by setting a protective device, the effect of preventing workers from being contaminated when the nozzle is not in use is achieved, avoiding the situation where the pipes inside the nozzle are contaminated and blocked. When the nozzle is not in use, it is exposed to the air and is easily attacked by various pollutants such as dust and stains. Over time, the internal pipes and other key components of the nozzle may suffer from performance degradation or even damage due to contamination. Attached Figure Description

[0029] Reference Figure 1 As shown, this utility model provides a technical solution: a spray gun for coating equipment, including a handle 1, with an installation device 4 at one end of the handle 1. The installation device 4 facilitates the installation of the fixing pipe 401 and the paint pipe 2 by the operator, avoiding the complex operation required for installing the paint pipe 2, which would otherwise take a long time to assemble, delaying the overall project progress. The complex installation also requires operators to maintain a specific posture for extended periods, leading to fatigue and discomfort, and reducing employee morale. The nozzle 3 has a protective device 5 on its arc-shaped surface. This device prevents contamination when the nozzle 3 is not in use, avoiding blockages in the internal pipes. When not in use, the nozzle 3 is exposed to air and is easily affected by dust, stains, and other contaminants. Over time, this contamination can cause performance degradation or even damage to key components such as the internal pipes.

[0030] The specific setup and function of the installation device 4 and the protective device 5 will be described in detail below.

[0031] Reference Figure 2 and Figure 3As shown in this embodiment: the installation device 4 includes a fixing pipe 401, which is fixedly connected to one end of the handle 1. A paint pipe 2 is slidably connected to the arc surface of the fixing pipe 401. A spray head 3 is fixedly connected to one end of the handle 1. Two mounting grooves 402 are formed on the arc surface of the fixing pipe 401. A first spring 403 is fixedly connected to the inner surface of the mounting groove 402. A blocking block 404 is fixedly connected to the other end of the first spring 403. Two threaded rods 405 are threadedly inserted into the arc surface of the paint pipe 2. A round block 406 is fixedly connected to one end of each threaded rod 405. Two round grooves 407 are formed on the inner surface of the fixing pipe 401. A leak-proof gasket 408 is slidably connected to one end of the fixing pipe 401, and the size of the leak-proof gasket 408 is adapted to the size of the fixing pipe 401. In the paint conveying pipeline system, the sealing between the fixing pipe 401 and the paint pipe 2 is enhanced to prevent paint leakage. A circular rod 409 is slidably connected to the inner surface of the circular groove 407. A movable frame 410 is slidably connected to the arc surfaces of the two circular rods 409. A handle 411 is fixedly connected to the arc surfaces of the circular rods 409. A second spring 412 is fixedly connected to the ends of the two circular rods 409 that are close to each other. The leak-proof pad 408 is limited to prevent it from falling off after installation. A baffle 413 is fixedly connected to the arc surface of the threaded rod 405. One side of the baffle 413 abuts against the fixed tube 401. By setting the baffle 413, when one side of the baffle 413 abuts against the arc surface of the fixed tube 401, the top of the blocking block 404 is exactly flush with one side of the arc surface of the fixed tube 401, which makes it easier for workers to disassemble the paint tube 2 and prevents the threaded rod 405 from rotating too much and inserting into the installation groove 402, which is not conducive to the operation of workers. The arc surface of the handle 1 is covered with water-absorbing rubber 414, which is made of rubber. When staff members' palms sweat, the absorbent rubber 414 absorbs the sweat and prevents their hands from slipping.

[0032] Reference Figure 4 and Figure 5 As shown, specifically, the protective device 5 includes a protective cover 51, which is slidably connected to the arc surface of the nozzle 3. The arc surface of the protective cover 51 has two circular holes 52, and the arc surface of the nozzle 3 has two placement grooves 53. A third spring 54 is fixedly connected to the inner surface of each placement groove 53, and a limit rod 55 is fixedly connected to the other end of the third spring 54. A screw 56 is threaded into the inner surface of the circular holes 52, and a rotating block 57 is fixedly connected to one end of the screw 56. When it is necessary to remove the protective cover 51, the screw 56 is rotated until the limit rod 55 disengages from the threaded hole of the protective cover 51, allowing the protective cover 51 to be directly removed from the surface of the nozzle 3.

[0033] Working principle: When the worker needs to install the paint pipe 2, first place the leak-proof pad 408 on one side of the fixed pipe 401, press the leak-proof pad 408 by hand until the fixed pipe 401 and the leak-proof pad 408 are tightly fitted, then press the handle 411 to compress the second spring 412 and slide it on the inner surface of the movable frame 410, then place the movable frame 410 between the two circular grooves 407, release the handle 411 and the second spring 412 to make the circular rod 409 spring to the inner surface of the circular groove 407, thereby adjusting the leak-proof pad 408. To limit the movement and prevent the leak-proof pad 408 from falling off, the round block 406 is rotated to drive the threaded rod 405 to rotate in the threaded hole of the paint tube 2 until the baffle 413 is a certain distance away from the paint tube 2. Then, the inner surface of the paint tube 2 is slid forward along the arc of the fixed tube 401 to press the blocking block 404 downward, thereby compressing the first spring 403 in the mounting groove 402. When the blocking block 404 springs into the threaded hole of the paint tube 2, it limits the movement of the paint tube 2. The water-absorbing rubber 414 absorbs the sweat from the hands.

[0034] When the staff needs to protect the nozzle 3, first slide the protective cover 51 along the surface of the nozzle 3, then rotate the screw 56 so that the top of the screw 56 disengages from the inner surface of the protective cover 51, and push the protective cover 51 again until it slides to the bottom. Then, due to the elasticity of the third spring 54, the limiting rod 55 is pushed into the round hole 52 of the protective cover 51 on the inner surface of the placement groove 53. Rotate the rotating block 57 to drive the screw 56. When the limiting rod 55 enters the inner surface of the round hole 52, the protective cover 51 can be installed and the nozzle 3 can be protected.
