[0016] Figure 2 It is a schematic diagram of the PLC controller operation panel of the present utility model. [Specific implementation method]

[0017] The present invention will be further described below with reference to the accompanying drawings:

[0018] like Figures 1 to 2As shown, a pickle ball compression force tester includes a body 1 and a PLC controller 2. The body 1 is provided with a pressure sensor 3, a positioning device 5 disposed on the pressure sensor 3 and used to position a pickle ball 4, a movable pressure plate 6 that can move up and down relative to the positioning device 5, and a driving device 7 that drives the movable pressure plate 6 to move and then cooperates with the positioning device 5 to compress the pickle ball 4 so that the pressure sensor 3 senses the pressure exerted on the pickle ball 4 when it is deformed. The driving device 7 and the pressure sensor 3 are respectively electrically connected to the PLC controller 2. The utility model presses the pickle ball 4 downward by driving the movable pressure plate 6 downward by the driving device 7. After the movable pressure plate 6 contacts the pickle ball 4 and continues to move downward relative to the pickle ball 4 by a relative displacement of 6.35 mm, when the pickle ball is compressed and deformed by 6.35 mm, the pressure sensor 3 is used to detect the pressure exerted by the pickle ball on the positioning device 5 to test the pressure that the pickle ball can withstand when compressed by 6.35 mm. The utility model is convenient and efficient to operate, breaking through the current predicament of the lack of dedicated pickle ball compression force testing equipment, and effectively ensuring the quality of pickle ball products.

[0019] Specifically, the drive device 7 includes a servo motor 71 electrically connected to the PLC controller 2, a reducer 72 connected to the output end of the servo motor 71, a screw 73 connected to the output end of the reducer 72, and a screw nut 74 fixedly mounted on the movable pressure plate 6 and driven by the screw 73 to move the movable pressure plate 6. When the servo motor 71 receives a signal from the PLC controller 2 and operates, the reducer 72 precisely controls the screw 73 to rotate at a low speed, causing the screw nut 74 to move along the screw 73, thereby driving the movable pressure plate 6 to move up and down within the machine body 1.

[0020] Specifically, the screw rod 73 is a ball screw and the screw nut 74 is a ball nut. Using the ball screw and the ball nut as the transmission mechanism can make the transmission more precise, efficient and stable.

[0021] Specifically, the positioning device 5 includes a receiving seat 51 provided on the pressure sensor 3 and a plurality of fixing blocks 52 provided on the upper end surface of the receiving seat 51. When the pickle ball 4 is placed on the receiving seat 51, the fixing blocks 52 are straightened so that the pickle ball 4 is positioned between the plurality of fixing blocks 52.

[0022] In order to ensure that the movable pressing plate 6 runs smoothly, a guide device 8 for guiding the movement of the movable pressing plate 6 is provided in the machine body 1 .

[0023] Specifically, the guide device 8 includes a guide post 81 vertically mounted within the machine body 1 and a slider 82 fixed to the movable pressure plate 6 and capable of moving up and down along the guide post 81. Two guide posts 81 are provided, one located on each of the two opposing side walls of the machine body 1, and two corresponding sliders 82 are provided, one located on each side of the movable pressure plate 6. When the servo motor 71 is running, the movable pressure plate 6 can move up and down smoothly under the guidance of the guide posts 81.

[0024] This pickleball compression force tester is controlled by PLC, with an operating voltage of 220V, a total power of less than 200W, a working stroke of 0-60mm, a stroke accuracy of ±0.05mm, and a pressure sensor with a detection pressure range of 0-110 lb and a pressure accuracy of ±0.15 lb.

[0025] During the transportation and installation of the equipment, make sure that the power switch and the red emergency stop switch 9 are turned off. Before testing, connect the tester to a 220V power supply, turn on the power switch at the rear of the equipment, and turn on the red emergency stop switch 9 next to the operation panel 10. After powering on, click the "star" in the middle of the touch screen to enter the control interface of the operation panel 10. Then, test the rebound force of the pickle ball using the following test method:

[0026] Press the return to zero button of the PLC controller 2, the tester returns to its initial state, and the movable pressure plate 6 returns to the origin; open the equipment safety door, put the pickle ball 4 to be tested into the receiving seat 51 and straighten the fixing block 52 to position the pickle ball 4 to prevent the pickle ball from moving; press the peel button of the PLC controller 2 to remove the weight of the pickle ball 4; press the start button of the PLC controller 2, the servo motor 71 runs through the reducer 72 to drive the screw 73 to drive the screw nut 74 to move the movable pressure plate 6 from the origin to the pickle ball 4 to be tested. When the movable pressure plate 6 contacts the pickle ball and the pressure sensor 3 detects that the pre-pressure is 1 pound, the relative position returns to zero; then the movable pressure plate 6 continues to move downward, and when the relative displacement is 6.35mm, this process takes 12-18 seconds, and the pressure sensor 3 sends the pressure data to the PLC controller 2, recording the force that the pickle ball 4 can withstand when compressed by 6.35mm. After the automatic operation is completed, the pickle ball compression force test result is displayed on the touch screen of the operation panel 10.

[0027] According to the ASTM F1888-09 standard test, if the force recorded above is less than 43 pounds, it is qualified.

[0028] To facilitate the calculation of the number of tests, the total record displayed on the touch screen of the operation panel 10 records the number of tests. Pressing the reset button of the PLC controller 2 can reset the record. Each ball needs to be tested twice, with one pressure perpendicular to the ball seam and one pressure parallel to the ball seam. If there is no seam, the first test is performed at a random position and the second test is performed perpendicular to the first test position.

[0029] During the test, if you need to stop midway, click the stop button; if you need to stop urgently, press the red emergency stop switch 9. When production is finished, you also need to press the emergency stop switch 9 and turn off the power switch.
