Description

Technical Field

[0001] This utility model relates to the field of industrial testing technology, and in particular to a horizontal spray coverage testing fixture. Background Technology

[0002] In industrial cleaning, electroplating, coating and other production processes, horizontal conveyor spray equipment (referred to as "horizontal machine") is widely used to uniformly spray flat workpieces such as plates, glass, and PCB substrates. The uniformity of the spray system coverage directly affects the treatment effect. Problems such as incomplete cleaning, uneven coating thickness, and etching deviation often stem from unreasonable spray pipeline layout or uneven pressure distribution caused by nozzle blockage.

[0003] Currently, the commissioning of sprinkler systems largely relies on manual observation of water marks for point testing. This involves placing ordinary paper towels or metal plates in the sprinkler area and judging the coverage area by observing the wetting marks. However, this method lacks a unified standard, is highly subjective, makes it difficult to distinguish differences in sprinkler intensity, lacks a means of area detection for the pressure distribution across the entire sprinkler surface, and cannot be reused.

[0004] Therefore, it is necessary to design a test fixture for the coverage range of a horizontal spray machine. Utility Model Content

[0005] In order to overcome the shortcomings of existing spray debugging methods that cannot reflect the differences in spray intensity in different areas, this utility model provides a horizontal machine spray coverage testing fixture.

[0006] The technical implementation scheme of this utility model is as follows: A horizontal spray coverage testing fixture includes a support frame, a controller, a water tank, spray heads, pressure sensors, connecting rods, a test frame, an anti-crossflow baffle, a wedge-shaped mounting block, a mounting groove, and a fixing and clamping structure. The controller is installed on the front left side of the support frame, and the water tank is connected to the upper rear side of the support frame. A detachable and replaceable spray head is connected to the front end of the water tank. Multiple regularly arranged pressure sensors are provided inside the lower side of the support frame, and the controller is electrically connected to each pressure sensor. Multiple connecting rods are vertically arranged on the upper part of the support frame, each... Multiple test frames are slidably mounted on the connecting rod. Adjacent test frames fit together but are independent of each other in the vertical direction. The bottom of each test frame is directly pressed against the pressure end face of an independent pressure sensor. Multiple anti-crossflow baffles are fixedly installed on the connecting rod and are located in the sliding gap between adjacent test frames. Wedge-shaped mounting blocks are fixedly connected to the rear side of the connecting rod. Multiple mounting slots are provided on the rear side of the support frame. The wedge-shaped mounting blocks are inserted into the corresponding mounting slots, and a fixing and clamping structure is provided between the mounting slots and the wedge-shaped mounting blocks.

[0007] Furthermore, the fixing and clamping structure includes a snap-fit ​​block, an elastic element, and a pull rod. Snap-fit ​​blocks are slidably connected inside the mounting groove. Each wedge-shaped mounting block has a snap-fit ​​hole in its center, and the snap-fit ​​blocks snap into the corresponding snap-fit ​​holes. An elastic element connects the snap-fit ​​block to the support frame. A pull rod is fixed to the top of each snap-fit ​​block, and the pull rod slides through the upper part of the support frame.

[0008] Furthermore, it also includes bolts and handles. Bolts are threadedly connected between the front side of the support frame and the front side of the connecting rod, and handles are fixed to the front end of the connecting rod.

[0009] Furthermore, it also includes a return pipe and a water pump. The lower part of the support frame is connected to the inside of the water tank via a return pipe, and a water pump is installed on the return pipe.

[0010] Furthermore, it also includes foot pads, with multiple foot pads located at the bottom of the support frame.

[0011] Furthermore, the test frame is made of stainless steel.

[0012] Beneficial effects:

[0013] 1. This utility model, by setting up multiple independent test frames and corresponding weighing sensors, can accurately measure the amount of water sprayed in each area, truly reflecting the uniformity and intensity distribution of the spray coverage, and avoiding the subjective errors of the traditional visual method.

[0014] 2. This utility model effectively prevents the spray water from flowing laterally along the connecting rod by setting an anti-crossflow baffle at the sliding gap between adjacent test frames, avoiding water volume interference between areas and ensuring that the measurement results are true and reliable.

Detailed Implementation

[0021] Example: A horizontal spray coverage testing fixture, such as... Figures 1-5 As shown, the system includes a support frame 1, a controller 2, a water tank 3, a spray head 4, a pressure sensor 5, a series rod 6, a test frame 7, an anti-crossflow baffle 8, a wedge-shaped mounting block 9, a mounting groove 101, and a fixing and clamping structure. The controller 2 is installed on the front left side of the support frame 1. The water tank 3 is connected to the upper rear side of the support frame 1. A detachable and replaceable spray head 4 is connected to the front end of the water tank 3. Multiple pressure sensors 5 are arranged in a regular pattern inside the lower side of the support frame 1. The controller 2 is electrically connected to each pressure sensor 5. Multiple series rods 6 are vertically arranged on the upper part of the support frame 1. Multiple test frames 7 are slidably mounted on each series rod 6. The test frames 7 are made of stainless steel, which ensures structural rigidity and prevents measurement deviations caused by deformation. The adjacent test frames 7 are fitted together and are independent of each other in the vertical direction. The bottom of each test frame 7 is directly pressed against the pressure end face of an independent pressure sensor 5, which is used to transfer the weight of the internal water to the pressure sensor 5 for independent measurement. Multiple anti-flow baffles 8 are fixedly installed on the connecting rod 6. The anti-flow baffles 8 are located at the sliding gap between adjacent test frames 7 to prevent the spray water from flowing laterally along the sliding contact surface between the connecting rod 6 and the test frame 7, thereby improving the measurement accuracy. Wedge-shaped mounting blocks 9 are fixedly connected to the rear side of the connecting rod 6. Multiple mounting slots 101 are provided on the rear side of the support frame 1. The wedge-shaped mounting blocks 9 are inserted into the corresponding mounting slots 101, and a fixing and clamping structure is provided between the mounting slots 101 and the wedge-shaped mounting blocks 9.

[0022] like Figure 2 , Figure 4 and Figure 5 As shown, the fixing and clamping structure includes a snap-fit ​​block 12, an elastic element 13, and a pull rod 14. The snap-fit ​​block 12 is slidably connected inside the mounting groove 101. The wedge-shaped mounting block 9 has a snap-fit ​​hole in the middle. The snap-fit ​​block 12 is snapped into the corresponding snap-fit ​​hole. The snap-fit ​​block 12 is connected to the support frame 1 by an elastic element 13. The top of the snap-fit ​​block 12 is fixedly connected to the pull rod 14, and the pull rod 14 slides through the upper part of the support frame 1.

[0023] like Figure 2 , Figure 3 and Figure 5As shown, it also includes bolts 10 and handles 11. Bolts 10 are threadedly connected between the front side of the support frame 1 and the front side of the connecting rod 6, and handles 11 are welded to the front end of the connecting rod 6.

[0024] like Figure 1 As shown, it also includes a return pipe 15 and a water pump 16. The lower part of the support frame 1 is connected to the inside of the water tank 3 and is connected by the return pipe 15. The water pump 16 is installed on the return pipe 15.

[0025] like Figure 1 As shown, it also includes foot pads 17. Multiple anti-slip foot pads 17 are provided at the bottom of the support frame 1 to enhance the stability of the equipment.

[0026] When using this utility model, the operator first installs the spray head 4 to be tested at the front end of the water tank 3, and then starts the spray system. The spray head 4 sprays water downwards, and the spray water falls into each test frame 7. Since the adjacent test frames 7 are in close contact with each other and slide up and down along the connecting rod 6, the spray water is separated into their own independent cavities, avoiding lateral flow.

[0027] The bottom of each test frame 7 is directly pressed onto an independent pressure sensor 5. As water accumulates, its weight increases. The pressure sensor 5 detects the load change in the area in real time and transmits the signal to the controller 2. The controller 2 generates a spray intensity distribution map based on the weight data of each area, which intuitively reflects the uniformity of the spray coverage. If the weight of a certain area is significantly lower, it indicates that the spray in that area is insufficient, which may be due to nozzle blockage or angle deviation.

[0028] After the test is completed, the user can pull the lever 14 upwards to compress the elastic element 13, causing the locking block 12 to disengage from the locking hole on the wedge-shaped mounting block 9, thereby releasing the fixing and locking structure. Then, the bolt 10 connecting the support frame 1 and the front side of the connecting rod 6 is unscrewed. Next, the user holds the handle 11 and pulls the entire connecting rod 6 and all the test frames 7 on it horizontally along the mounting groove 101 to achieve overall maintenance. The water inside the test frame 7 can be poured directly into the support frame 1 and then sent back to the water tank 3 by the return pipe 15 and the water pump 16 to achieve water resource recycling. When it is necessary to reinstall the connecting rod 6, simply reinsert the wedge-shaped mounting block 9 into the mounting groove 101. The locking block 12 will be pushed up by the wedge surface and then automatically locked into the locking hole by the elastic element 13 to complete the quick installation and locking.
