Description

Technical Field

[0001] This utility model relates to the field of monitoring device technology, specifically a device for monitoring under-spraying and under-spraying in spraying equipment. Background Technology

[0002] Spraying is a very common process technology. By spraying the surface of a workpiece, not only can the aesthetics of the workpiece be improved, but the workpiece itself can also be given excellent physical properties such as corrosion resistance.

[0003] Common parameter settings for spraying equipment include turntable speed and flow rate. By adjusting the corresponding parameters, the spraying volume and spray point morphology can be changed to further meet customer needs. However, there is a problem: the flow rate of each nozzle cannot be effectively monitored. In the production process, it is inevitable to encounter situations where dry material or foreign objects get stuck in the nozzle. If this situation occurs, it will result in less spraying volume in that area. If this problem is not resolved continuously, it will cause the physical property test to fail. If the dry material is washed away by hydraulic pressure during the production process, it will still cause product quality risks. Therefore, a device for monitoring under-spraying and under-spraying in spraying equipment is proposed. Utility Model Content

[0024] Example

[0025] In existing technologies, common parameter settings for spraying equipment include turntable speed and flow rate. By adjusting the corresponding parameters, the spraying volume and spray point morphology can be changed to further meet customer needs. However, there is a problem: the flow rate of each nozzle cannot be effectively monitored. During the production process, it is inevitable to encounter situations where dry material or foreign objects get stuck in the nozzle. If this situation occurs, it will result in a lower spraying volume in that area. If this problem is not resolved continuously, it will cause the physical property test to fail. Even if the dry material is washed away by hydraulic pressure during the production process, it will still pose a product quality risk.

[0026] Please see Figure 1-5This utility model provides a technical solution: a device for monitoring under-spraying and under-spraying in spraying equipment, comprising a spray paint box 1 for use in spraying equipment, a branch pipe 2 inside the spray paint box 1, a slurry pipe 3 at the end of the branch pipe 2, the end of the slurry pipe 3 penetrating the bottom of the spray paint box 1, and a nozzle 4 at the end of the slurry pipe 3, a cover plate 5 hinged to one side of the top of the spray paint box 1, a clamping plate 6 fixed to the top surface of the cover plate 5, a limiting plate 7 fixed to the top surface of the cover plate 5, a locking component 8 on the surface of the limiting plate 7, a fixing structure 9 on the surface of the locking component 8, the fixing structure 9 being interconnected with the spray paint box 1, and a sealing component 10 on the surface of the fixing structure 9, the sealing component 10 being interconnected with the clamping plate 6. Next, to facilitate staff understanding whether there is any blockage inside the nozzle 4, a monitoring mechanism 11 is provided on the surface of the slurry pipe 3. The monitoring mechanism 11 includes a pressure sensor 1101, a wire 1102, and an indicator 1103. The pressure sensor 1101 is threaded to the top surface of the branch pipe 2. A sealing gasket is provided at the joint between the branch pipe 2 and the pressure sensor 1101. The wire 1102 is electrically connected to the output end of the pressure sensor 1101. The end of the wire 1102 passes through the interior of the wire 1102. The end of the wire 1102 is electrically connected to the indicator 1103. In order to cooperate with the locking assembly 8 to improve the stability of the fixing structure 9 when it is stationary, two sets of limit plates 7 are provided, and each set of limit plates 7 has two plates.

[0027] To ensure smooth displacement of the sealing component 10, the clamping plate 6 has an "L"-shaped structure, and two clamping plates 6 are provided. To prevent the fixing structure 9 from operating under external vibration and reducing its fixing effect, a locking assembly 8 is provided. The locking assembly 8 includes a rotating plate 801 and a horizontal plate 802. The rotating plate 801 is attached to the limiting plate 7, and the horizontal plate 802 is hinged to the end of the rotating plate 801. To fix the sealing component 10 and the cover plate 5, a fixing structure 9 is provided. The fixing structure 9 includes a top plate 901 and a threaded rod 902. The top plate 901 is fixed to the end of the horizontal plate 802, and the threaded rod 902 is fixed to the bottom center of the top plate 901. The threaded rod 902 is connected to the spray paint box 1. The side wall threaded connection, during normal use, only one of the several threaded rods 902 is threadedly connected to the side wall of the paint box 1. The locking component 8 is provided in two sets, and the two sets of locking components 8 are symmetrically distributed about the longitudinal central axis of the top plate 901. In order to seal the through hole of the wire 1102 on the surface of the cover plate 5 and enhance the sealing of the inside of the paint box 1, a sealing component 10 is provided. The sealing component 10 includes a slider 1001 and a sliding plate 1002. The slider 1001 is threadedly sleeved on the surface of the threaded rod 902. The slider 1001 slides against the cover plate 5. The sliding plate 1002 is fixed to the top surface of the slider 1001. The sliding plate 1002 slides against the clamping plate 6.

[0028] The pressure sensor 1101 is model SSM-P200. This model of sensor is a diaphragm design, which can appropriately avoid the influence of particles in the slurry on the sensor. Its supplier is Shanghai Dairong Technology Co., Ltd.; the indicator 1103 is model TD-260T, and its supplier is Xiaochuan Industrial Equipment Shenzhen Co., Ltd.

[0029] The working principle or structural principle is as follows: First, during daily use, the slurry can be delivered to the surface of the nozzle 4 through the slurry pipe 3 to achieve the spraying operation. If a blockage occurs inside the nozzle 4, the amount of slurry sprayed will decrease, which will increase the slurry content inside the slurry pipe 3 and the branch pipe 2. At this time, the pressure inside the branch pipe 2 will increase. The pressure sensor 1101 can transmit the pressure inside the branch pipe 2 to the surface of the indicator 1103 through the wire 1102. By observing the indicator 1103, the operator can find out the pressure inside the branch pipe 2 and thus infer whether the nozzle 4 is blocked.

[0030] If the pressure sensor 1101 needs to be maintained and cleaned, the operator can first rotate the rotating plate 801 to disengage it from the limiting plate 7. Then, the horizontal plate 802 drives the top plate 901 and the threaded rod 902 to rotate, so that the threaded rod 902 is disengaged from the paint box 1 and the slider 1001. After that, the slider 1001 and the sliding plate 1002 can be pulled off the cover plate 5, and the cover plate 5 can be flipped. During the flipping process, there will be no movement obstruction due to the wire 1102. Finally, the pressure sensor 1101 can be removed from the slurry pipe 3.

[0031] In summary, this device has advantages such as being able to monitor and being easy to maintain.
