[0040] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0041] The nozzle plate testing device 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings. The nozzle plate 200 can be installed on a material rejection device (such as a color sorter) in actual use, and can be used for material screening, such as removing materials that do not need to be retained, and using airflow to blow away materials that do not need to be retained. The nozzle plate 200 has a plurality of jet ports 201 arranged at intervals, and the jet ports 201 can spray airflow to blow away materials that do not need to be retained. Whether the air outlet of the jet port 201 is smooth directly affects the quality of the screened material. The testing device 100 can test the nozzle plate 200 to detect the jet condition of each jet port 201.

[0042] like Figure 1-Figure 2As shown, according to the nozzle plate testing device 100 of an embodiment of the present invention, the testing device 100 includes a base plate 1, a detection component 2 for detecting the jetting condition of each jet port 201, an adapter plate 3, an air supply connector 4 and a driving module 5.

[0043] Specifically, refer to Figure 1-Figure 2 The nozzle plate 200 is detachably mounted on the base plate 1, the detection assembly 2 is disposed on the base plate 1, a plurality of spaced apart air holes 31 are provided on the adapter plate 3, each jet port 201 is connected to at least one air hole 31, the air supply connector 4 is switchedly connected to the plurality of air holes 31 to switch to guide air to the corresponding air holes 31, the drive module 5 is connected to the air supply connector 4, and the drive module 5 drives the air supply connector 4 to move to switchly connect to the plurality of air holes 31.

[0044] It can be understood that when the nozzle plate 200 needs to be tested, the nozzle plate 200 is installed on the bottom plate 1. When the test is completed, the nozzle plate 200 is removed from the bottom plate 1. The nozzle plate 200 is detachably installed on the bottom plate 1 to facilitate the installation and removal of the nozzle plate 200, so that the test device 100 can be universal and the test device 100 can detect nozzle plates 200 of various specifications. The bottom plate 1 can also be used as a support member to support the detection component 2, the adapter plate 3, the air supply connector 4, the drive module 5 and other components of the test device 100.

[0045] Among them, when the detection component 2 detects the jetting condition of each jet port 201, it is necessary to supply air to the jet port 201 so that the jet port 201 can eject airflow. The air supply connector 4 is connected to the vent 31 of the adapter plate 3 to supply air to the vent 31. The vent 31 is connected to the jet port 201 to guide the airflow to the jet port 201. Thus, the jet port 201 can eject airflow. The detection component 2 can judge the smoothness of the air outlet of the jet port 201 according to the airflow ejected from the jet port 201, and then identify the jet port 201 with poor air outlet effect. The detection component 2 can detect the parameters of the airflow ejected from the jet port 201, such as waveform, flow rate, speed, etc., and the specific detection items of the detection component 2 are not too limited here. As long as the items that can judge the air outlet condition of the jet port 201 through detection can fall into the protection scope of the present invention.

[0046] As a feasible method, the detection component 2 can automatically analyze the detection results and generate conclusion data, so that the detection personnel can intuitively know the gas outlet conditions of the air jet 201, thereby saving the time of manual data recording and avoiding the misjudgment of the gas outlet conditions of the air jet 201 due to manual recording errors. Of course, the detection component 2 can also only play the detection function, and the data is recorded manually, and the function of the detection component 2 is not too limited here.

[0047] Among them, a plurality of spaced apart air holes 31 are provided on the adapter plate 3, and each air jet 201 is connected to at least one air hole 31, that is, each air jet 201 can be connected to one air hole 31, thereby, one air hole 31 can supply air to the corresponding air jet 201, ensuring that the air jet 201 can eject airflow during detection; each air jet 201 can also be connected to a plurality of air holes 31, thereby, the air supply volume of each air jet 201 can be increased, ensuring that each air jet 201 has sufficient air volume during detection, making the detection more accurate and smooth. The air supply connector 4 is switched to communicate with multiple air holes 31 so that the air supply connector 4 can be switched to communicate with each air hole 31 on the adapter plate 3, and then air can be guided to each air hole 31, thereby achieving the purpose of guiding air into all the air jets 201 in sequence, and achieving the purpose of supplying air to the air jets 201 of the entire nozzle plate 200. The driving module 5 is connected to the air supply connector 4, so that the driving module 5 can drive the air supply connector 4 to move to switch communication with each air hole 31. In this way, the test device 100 can realize automatic air supply, and can eliminate the step of manually plugging and unplugging the air supply connector 4 from the air hole 31, thereby avoiding manual errors, improving the air supply efficiency and accuracy (including the accuracy of the air supply volume and the accuracy of the air supply position), thereby improving the detection efficiency and accuracy.

[0048] In the related art, the test of nozzle plates is mostly manual testing, which requires manual insertion of the air supply connector to the air nozzle corresponding to the nozzle plate to be tested. This wastes a lot of time in plugging and unplugging the air supply connector. Moreover, manual operation has many uncertain factors, low efficiency, and high error rate. It is easy to cause insufficient air supply or wrong position, which leads to errors in test results.

[0049] According to the nozzle plate testing device 100 of the embodiment of the present invention, the driving module 5 is connected to the air supply connector 4, so that the driving module 5 can drive the air supply connector 4 to move, so that the air supply connector 4 can switch to communicate with each vent hole 31. Therefore, the testing device 100 can realize automatic air supply, and the step of manually plugging and unplugging the air supply connector 4 from the vent hole 31 can be removed, thereby avoiding manual errors, improving the air supply efficiency and accuracy (including the accuracy of the air supply amount and the accuracy of the air supply position), thereby improving the detection efficiency and accuracy.

[0050] In some embodiments of the present invention, Figure 1-Figure 2The driving module 5 may include a first driving component 51 and a second driving component 52. The first driving component 51 is connected to the air supply connector 4 to drive the air supply connector 4 to move in the up-down direction. The second driving component 52 is connected to the air supply connector 4 to drive the air supply connector 4 to move in the horizontal plane. It should be noted that the air vents 31 on the adapter plate 3 may be arranged in multiple rows and columns. The second driving component 52 drives the air supply connector 4 to move in the horizontal plane so that the air supply connector 4 can move to the position of each air vent 31. The first driving component 51 drives the air supply connector 4 to move up and down so that the air supply connector 4 can be easily inserted into and removed from the air vent 31.

[0051] like Figure 1-Figure 2 As shown, according to some embodiments of the present invention, the second driving component 52 may include a first linear direction driving member 521 and a second linear direction driving member 522, the first linear direction driving member 521 is arranged on the base plate 1 and includes a first movable part 5211 movable along the first linear direction F1; the second linear direction driving member 522 is arranged on the first movable part 5211, and the second linear direction driving member 522 includes a second movable part 5221 movable along the second linear direction F2; the first driving component 51 is arranged on the second movable part 5221, wherein the first linear direction F1 and the second linear direction F2 are arranged vertically.

[0052] It can be understood that the first movable component 5211 can drive the second linear driving component 522 to move along the first linear direction F1, and at the same time, it also drives the second movable component 5221 to move along the first linear direction F1. Therefore, the second movable component 5221 drives the first driving component 51 to move along the first linear direction F1 and the second linear direction F2. Since the first driving component 51 is connected to the air supply connector 4, it can drive the air supply connector 4 to move along the first linear direction F1 and the second linear direction F2, thereby facilitating the movement of the air supply connector 4 to the position of each air vent 31.

[0053] refer to Figure 2 According to some embodiments of the present invention, the first linear direction driving member 521 may include a rack plate 5212, a gear 5213 and a first driving motor 5214, the rack plate 5212 is arranged on the base plate 1 and extends along the first linear direction F1; the gear 5213 is engaged with the rack plate 5212 to move along the first linear direction F1; the first driving motor 5214 is connected to the gear 5213 to drive the gear 5213 to rotate and move with the gear 5213, and the first driving motor 5214 is arranged on the first movable component 5211 to drive the first movable component 5211 to move.

[0054] The first drive motor 5214 can drive the gear 5213 to rotate, and the gear 5213 can be meshed with the rack plate 5212 fixed on the bottom plate 1, so that the gear 5213 can move along the extension direction of the rack plate 5212 (i.e., the first linear direction F1), and the movement of the gear 5213 can drive the first drive motor 5214 connected thereto to move along the first linear direction F1, and the first drive motor 5214 can drive the first movable component 5211 connected thereto to move along the first linear direction F1. Therefore, the first linear direction driving member 521 can realize the movement of the first movable component 5211 along the first linear direction F1. In addition, the gear 5213 and the rack plate 5212 can be used to convert the rotational motion of the first drive motor 5214 into the linear motion of the first movable part 5211, thereby facilitating the spatial arrangement of the first drive motor 5214, the gear 5213, the rack plate 5212 and the first movable part 5211. Moreover, the gear 5213 and the rack plate 5212 have high transmission efficiency and a long service life.

[0055] In some embodiments of the present invention, Figure 1 The second linear direction driving member 522 may include a second driving motor 5222 and a first lead screw 5223. The second driving motor 5222 is disposed on the first movable part 5211. The second driving motor 5222 is connected to the first lead screw 5223 to drive the first lead screw 5223 to rotate. The second movable part 5221 cooperates with the first lead screw 5223 to move along the second linear direction F2. The second driving motor 5222 drives the first lead screw 5223 to rotate. The first lead screw 5223 cooperates with the second movable part 5221 to drive the second movable part 5221 to move along the second linear direction F2. Since the second driving motor 5222 is disposed on the first movable part 5211, the first movable part 5211 can drive the second linear direction driving member 522 to move along the first linear direction F1 as a whole, and also drive the second movable part 5221 to move along the first linear direction F1. Thus, the second movable part 5221 can move along both the first linear direction F1 and the second linear direction F2.

[0056] According to some embodiments of the present invention, reference Figure 1-Figure 2 The first driving component 51 may include a cylinder body 511, an actuator 512 and a movable part 513. The cylinder body 511 is connected to the second movable part 5221. The actuator 512 is arranged in the cylinder body 511. The movable part 513 is connected to the actuator 512. It can be understood that the cylinder body 511 can drive the actuator 512 to move up and down, and the actuator 512 can drive the movable part 513 to move up and down. The air supply connector 4 is arranged on the movable part 513, thereby, the air supply connector 4 can realize the movement in the up and down directions.

[0057] In some embodiments of the present invention, Figure 1 As shown, the test device 100 also includes an air supply device 6 suitable for communicating with an external air source. Specifically, the air supply device 6 can be connected to the second movable part 5221, or can be arranged on other parts, and the air supply device 6 is in communication with the air supply connector 4. Specifically, the air supply device 6 can be a spray valve, one side of which is connected to the external air source, and the spray valve includes a spray valve outlet 61, and the spray valve outlet 61 is in communication with the air supply connector 4. Thus, the air supply device 6 can input the air flow to the air supply connector 4, and the air supply device 6 is connected to the second movable part 5221 so that the air supply device 6 can move with the second movable part 5221. Since the first drive assembly 51 is also connected to the second movable part 5221, and the air supply connector 4 is connected to the first drive assembly 51, the air supply device 6 and the air supply connector 4 can move synchronously, thereby facilitating the connection between the air supply device 6 and the air supply connector 4.

[0058] Furthermore, combined with Figure 1 The air supply device 6 and the air supply connector 4 can be connected through the connecting pipe 62. The air supply device 6 and the air supply connector 4 move synchronously so that the length of the connecting pipe 62 can be shorter, thereby saving the connecting pipe 62; at the same time, there is no problem of pulling the connecting pipe 62, which can extend the service life of the connecting pipe 62; in addition, it can also avoid the connecting pipe 62 being hooked on other components due to the movement of the connecting pipe 6 with the air supply connector 4 due to the air supply device 6 not moving, thereby avoiding the problem of the connecting pipe 62 being pulled out of the air supply device 6 or the air supply connector 4, resulting in the failure of the air supply function.

[0059] In some embodiments of the present invention, Figure 4-Figure 5 As shown, the test device 100 also includes a bulkhead straight connector 10, and a pressing portion 110 is provided at both ends of the bulkhead straight connector 10. Each pressing portion 110 can work separately. When the pressing portion 110 is pressed, the components that need to be inserted into the bulkhead straight connector 10 can be easily inserted, and the components that need to be pulled out of the bulkhead straight connector 10 can be easily pulled out. The vent hole 31 includes a first hole section 311 and a second hole section 312. The diameter of the first hole section 311 is larger than the diameter of the second hole section 312, so that a stop portion is formed at one end of the first hole section 311 close to the second hole section 312. The bulkhead straight connector 10 is provided at the first hole section 311, and the pressing portion 110 at one end of the bulkhead straight connector 10 stops at the stop portion.

[0060] It should be noted that one end of the partition straight connector 10 close to the second hole section 312 can be connected to the air supply connector 4, and the other end of the partition straight connector 10 can be connected to the air jet 201, for example, it can be connected to the air jet 201 through the connecting pipe 120, thereby, the partition straight connector 10 can guide the airflow in the air supply connector 4 to the air jet 201. The pressing portion 110 at one end of the partition straight connector 10 stops at the stop portion, so that the pressing portion 110 is pressed, thereby, it is convenient to insert and remove the air supply connector 4 from the partition straight connector 10; and the pressing portion 110 at the other end of the partition straight connector 10 is not pressed, so that the connecting pipe 120 inserted into the partition straight connector 10 can be clamped, which can prevent the connecting pipe 120 from loosening from the partition straight connector 10 and causing the airflow to be unable to be input to the air jet 201.

[0061] According to some embodiments of the present invention, Figure 2 The detection component 2 is movably arranged on the bottom plate 1 to detect the jet condition of each jet port 201. The testing device 100 further includes a position adjustment component 7, which is connected to the detection component 2 to drive the detection component 2 to move. It can be understood that the detection component 2 can be moved on the bottom plate 1 to facilitate the detection component 2 to detect the jet condition of each jet port 201, and the position adjustment component 7 can provide power for the detection component 2 to drive the detection component 2 to move.

[0062] like Figure 2 As shown, in some embodiments of the present invention, the position adjustment component 7 includes a third drive motor 71, a second lead screw 72 and a fourth movable component 73. The third drive motor 71 is arranged on the bottom plate 1, and the third drive motor 71 is connected to the second lead screw 72 to drive the second lead screw 72 to rotate. The fourth movable component 73 cooperates with the second lead screw 72 to move along the arrangement direction of the plurality of jet ports 201, and the detection component 2 is arranged on the fourth movable component 73. Among them, the third drive motor 71 can drive the second lead screw 72 to rotate, and the second lead screw 72 can extend along the arrangement direction of the plurality of jet ports 201. The rotation of the second lead screw 72 drives the fourth movable component 73 to move along the arrangement direction of the plurality of jet ports 201, and then drives the detection component 2 to move along the arrangement direction of the plurality of jet ports 201, thereby facilitating the detection component 2 to detect the jet condition of each jet port 201.

[0063] Further, refer to Figure 2The third drive motor 71 and the second lead screw 72 can be connected through a pulley assembly 74, the pulley assembly 74 includes a first pulley 741, a second pulley 742 and a belt, the third drive motor 71 is connected to the first pulley 741, the first pulley 741 and the second pulley 742 are connected through a belt, and the second lead screw 72 is connected to the second pulley 742, thereby, the third drive motor 71 drives the first pulley 741 to rotate, the first pulley 741 drives the second pulley 742 to rotate through the belt, and the second pulley 742 drives the second lead screw 72 to rotate. The setting of the pulley assembly 74 can facilitate the spatial arrangement of the position adjustment assembly 7 and reduce the volume of the test device 100 in the arrangement direction of the multiple jet ports 201.

[0064] Furthermore, combined with Figure 2 The position adjustment component 7 may further include a guide shaft 75, which is fixed to the base plate 1 via a mounting block 76. A slider 77 is sleeved on the guide shaft 75, and the slider 77 is connected to the fourth movable component 73 via a connecting piece 78. The guide shaft 75 may provide a guiding function for the fourth movable component 73, so that the fourth movable component 73 may move stably and reliably along the second lead screw 72.

[0065] In some embodiments of the present invention, Figure 2 As shown, the test device 100 also includes a height adjustment component 8, which is arranged on the position adjustment component 7, and the height adjustment component 8 is connected to the detection component 2 to adjust the height of the detection component 2. It can be understood that the height adjustment component 8 is arranged on the position adjustment component 7 so that the height adjustment component 8 can move with the position adjustment component 7. Specifically, the height adjustment component 8 can be arranged on the fourth movable component 73, and move along the arrangement direction of the plurality of air jets 201 with the fourth movable component 73, and the height adjustment component 8 can also adjust the height of the detection component 2, thereby allowing the detection component 2 to move more accurately to the center of the air jet 201, so that the air jet condition of the air jet 201 can be detected more accurately. In addition, the position adjustment component 7 and the height adjustment component 8 jointly adjust the position of the detection component 2 so that the detection component 2 can move accurately to any position of the air jet 201, thereby facilitating the R&D personnel to obtain the air jet condition in the air jet 201 area, such as the pressure distribution condition.

[0066] According to some embodiments of the present invention, reference Figure 3The testing device 100 further includes a positioning device 20 for positioning the nozzle plate 200. The positioning device 20 includes a first positioning member 210 for limiting the movement of the nozzle plate 200 along the first linear direction F1, a second positioning member 220 for limiting the movement of the nozzle plate 200 along the second linear direction F2, and a third positioning member 230 for limiting the movement of the nozzle plate 200 along the up-down direction. Thus, the nozzle plate 200 can be stably placed on the bottom plate 1, so that the detection component 2 can find the center position of the jet port 201 accurately, thereby improving the accuracy of the detection component 2 in measuring the jet condition of the jet port 201.

[0067] In some embodiments of the present invention, Figure 2 The test device 100 also includes an electrical box 9 electrically connected to the drive module 5. The base plate 1 is arranged on the electrical box 9. The electrical box 9 includes a first operation button 91, a second operation button 92 and a host computer 93. The first operation button 91 can be used to control the circuit on and off of the test device 100.
