Description

Technical Field

[0001] The utility model relates to the technical field of nozzle spray pressure detection, in particular to a nozzle spray pressure detection device. Background Art

[0002] Bottle washing machine is a device for cleaning and sterilizing the inside and outside of bottles. When it is working, some nozzles often have insufficient pressure, excessive pressure or blockage, which will affect the cleaning and sterilization effect of the bottle, affect product quality and safety, and cause losses to customers.

[0003] In the prior art, the nozzle spray detection plate is rotated around an axis to a corresponding angle, and then whether the nozzle is blocked or the pressure is abnormal is determined based on whether it can be detected by the detection unit. The disadvantage of this structure is that it is difficult to adjust the detection accuracy: for example, when spraying a small bottle, the nozzle spray pressure fluctuation range can be allowed to be larger because it will not affect the flushing of the small bottle; for example, when spraying a slender bottle, in order to ensure that the nozzle can spray to the bottom of the slender bottle, it is necessary to limit the nozzle spray pressure fluctuation range to a smaller range. For different bottle types, it is difficult to adjust the corresponding nozzle spray pressure detection fluctuation range, and the versatility is relatively poor. Utility Model Content

[0030] See also Figure 1-2 As shown, this embodiment provides a device for detecting nozzle spray pressure, comprising a first mounting bracket 1, and a rotating assembly 2 rotatably arranged on the first mounting bracket 1 around a first axis. The first mounting bracket 1 is connected to a bottle washing machine frame or the ground through a first bracket slot 13, and the first axis is arranged along the front-to-back horizontal direction. The front-to-back horizontal direction here refers to Figure 2 The direction perpendicular to the paper.

[0031] The rotating assembly 2 includes a detection plate 21 and a force plate 22 connected to each other, and the force plate 22 is used to bear the upward spray pressure of the nozzle 3 below to drive the detection plate 21 to rotate around the first axis. In this embodiment, in the initial state, the force plate 22 is parallel to the horizontal plane, and the initial state here refers to the state when the spray pressure of the nozzle 3 is the set value.

[0032] In this embodiment, the rotating assembly 2 further includes a connecting plate 23 connected between the detection plate 21 and the force-bearing plate 22, and a counterweight 24 movably arranged on the connecting plate 23 along the length extension direction of the connecting plate 23. By setting the counterweight 24, the position of the counterweight 24 can be adjusted according to different set values ​​of the spray pressure of the nozzle 3, so that the force-bearing plate 22 can always remain horizontal in the initial state, so as to facilitate the subsequent detection of the spray pressure of the nozzle 3.

[0033] See also Figure 1 As shown, the connecting plate 23 is provided with a second adjustment slot 231 arranged in the left-right direction, and the counterweight block 24 can be slidably arranged in the second adjustment slot 231 along the length extension direction of the second adjustment slot 231. When the counterweight block 24 is adjusted to a proper position, a limiting member or a locking member (not shown in the figure) is used to prevent the counterweight block 24 from continuing to move.

[0034] The force-bearing plate 22 and the connecting plate 23 are coplanar or parallel to each other. In this embodiment, the force-bearing plate 22 and the connecting plate 23 are coplanar, and the length extension direction of the connecting plate 23 is perpendicular to the length extension direction of the detection plate 21. The length extension direction of the connecting plate 23 is the left and right horizontal direction (i.e. Figure 2 The length of the detection plate 21 extends in the vertical direction (i.e. Figure 2 in the vertical direction).

[0035] See also Figure 1-2 As shown, the above-mentioned detection device for nozzle spray pressure also includes a second mounting bracket 4, a proximity switch 5 movably arranged on the second mounting bracket 4, and the proximity switch 5 and the detection plate 21 are arranged in a spaced relationship along a direction parallel to the first axis. Through this arrangement, the proximity switch 5 has an upper limit position and a lower limit position, and the upper limit position is located above the lower limit position. The second mounting bracket 4 is connected to the bottle washing machine frame or the ground through the second bracket groove 42.

[0036] When the proximity switch 5 is at the upper limit position, the turning radius of the sensing area at the corresponding height of the detection plate 21 is the smallest; when the proximity switch 5 is at the lower limit position, the turning radius of the sensing area at the corresponding height of the detection plate 21 is the largest.

[0037] By setting a proximity switch 5 that can move up and down on the second mounting frame, when the proximity switch 5 is at the upper limit position, the turning radius of the sensing area at the corresponding height of the detection plate 21 is the smallest, and in the sensing area of ​​the same width, the angle that the force plate 22 can rotate around the first axis is the largest, so the fluctuation range of the nozzle 3 spray pressure that can be measured is the largest; when the proximity switch 5 is at the lower limit position, the turning radius of the sensing area at the corresponding height of the detection plate 21 is the largest, and in the sensing area of ​​the same width, the angle that the force plate 22 can rotate around the first axis is the smallest, so the fluctuation range of the nozzle 3 spray pressure that can be measured is the smallest. Therefore, the detection device for nozzle spray pressure can be applicable to the requirements of different bottle types for the detection fluctuation range of nozzle 3 spray pressure, and has relatively good versatility.

[0038] Specifically, between the upper limit position and the lower limit position of the proximity switch 5, the corresponding fluctuation range of the spray pressure of the nozzle 3 is different. The closer to the upper position, the larger the fluctuation range of the spray pressure of the nozzle 3 is allowed, and the closer to the lower position, the smaller the fluctuation range of the spray pressure of the nozzle 3 is allowed. During actual detection, the detection height of the proximity switch 5 can be adjusted according to the fluctuation range of the spray pressure of the nozzle 3 allowed by the corresponding bottle type.

[0039] In this embodiment, the width of the detection plate 21 gradually decreases from top to bottom, that is, the width of the sensing area of ​​the detection plate 21 gradually decreases from top to bottom.

[0040] Through this setting, when the proximity switch 5 is at the upper limit position, the width of the corresponding sensing area of ​​the detection plate 21 is the largest, and the spray pressure of the nozzle 3 can be allowed to have a larger fluctuation range; when the proximity switch 5 is at the lower limit position, the width of the corresponding sensing area of ​​the detection plate 21 is the smallest, and the spray pressure of the nozzle 3 can be limited to a smaller fluctuation range. By respectively increasing and decreasing the upper limit and lower limit of the fluctuation range of the spray pressure of the nozzle 3, the versatility of the detection device can be further improved.

[0041] See also Figure 1 As shown, the second mounting bracket 4 is provided with a first adjustment slot 41 arranged in the up-down direction, and the proximity switch 5 can be slidably arranged in the first adjustment slot 41 along the length extension direction of the first adjustment slot 41. When the proximity switch 5 is adjusted to a proper position, a limiter or a locking member (not shown in the figure) is used to prevent the proximity switch 5 from continuing to move.

[0042] See also Figure 1-2As shown, the left end of the first mounting bracket 1 is provided with a mounting groove 11, the groove direction of the mounting groove 11 is arranged in the up-down direction, the detection plate 21 is rotatably connected in the mounting groove 11 through its upper end, and the upper end of the detection plate 21 is spaced from the groove bottom of the mounting groove 11. Through this arrangement, it is possible to avoid interference between the detection plate 21 and the mounting groove 11 when rotating.

[0043] In this embodiment, a limit assembly 12 for limiting the rotation of the detection plate 21 is further provided at the left end of the first mounting bracket 1. The limit assembly 12 includes an upper limit member 121 located above the mounting groove 11 and a lower limit member 122 located below the mounting groove 11. Through this arrangement, the detection plate 21 can be prevented from rotating at a large angle, thereby preventing the detection plate 21 from hitting other components and causing damage during the rotation process.

[0044] See also Figure 3 As shown, in another embodiment, a plurality of nozzles 3 are arranged on a rotating disk 6 in a sequentially spaced arrangement along the circumferential direction, and the rotating disk 6 can rotate around its own axis. The rotating disk 6 is located below the force plate 22, and the force plate 22 is located directly above the rotation path of the nozzle 3. The length of the force plate 22 along the travel direction of the plurality of nozzles 3 is greater than the interval between the plurality of nozzles 3. This embodiment is suitable for the case where the fluctuation range of the spray pressure of the nozzle 3 is large. Through this setting, it can be ensured that during the entire detection process, at least one nozzle 3 can spray to the force plate 22, and the sensing area of ​​the detection plate 21 is always maintained to correspond to the proximity switch 5, so that the proximity switch 5 can always detect the sensing signal. The control power supply of the background only needs to simply monitor the presence or absence of the proximity switch 5 signal to determine whether the spray pressure of the nozzle 3 is abnormal, which can avoid the frequent switching of the proximity switch 5 signal due to the abnormal spray pressure of the nozzle 3, which not only reduces the calculation amount of the program, but also reduces the rotation frequency of the detection plate 21 and increases its service life.

[0045] The working process of this embodiment is described in detail below:

[0046] Before testing, select the appropriate spray pressure fluctuation range according to the bottle type to be sprayed, that is, adjust the height of the proximity switch 5, and then spray the force-bearing plate 22 upward through the nozzle 3 that can spray the standard spray pressure, and adjust the position of the counterweight 24 to make the force-bearing plate 22 in a horizontal balanced state. At this time, the detection plate 21 is in a vertical state, and the proximity switch 5 is aligned with the middle position of the sensing area of ​​the detection plate 21;

[0047] During the inspection, the nozzles 3 are passed under the force-bearing plate 22 one by one. When the proximity switch 5 has an induction signal, it means that the spray pressure of the nozzle 3 is within the fluctuation range and the nozzle 3 is qualified; when the proximity switch 5 has no induction signal, it means that the spray pressure of the nozzle 3 is not within the fluctuation range and the nozzle 3 is unqualified.

[0048] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
