Description

Technical Field

[0001] This utility model relates to the field of nozzle testing devices, and in particular to a nozzle testing device for improving air supply sealing. Background Technology

[0002] A spray nozzle, also known as an atomizing nozzle, is a device that atomizes liquid and sprays it out, suspending it evenly in the air. Its working principle involves using internal pressure to force the liquid into the nozzle. Under the influence of the internal structure and pressure, the liquid is atomized into particles with a diameter of approximately 15-60 micrometers, which are then ejected through the nozzle outlet. Spray nozzles are widely used in various aerosol products, such as perfumes, cosmetics, and daily necessities.

[0003] In the prior art, Chinese invention application with publication number "CN110044597A" and patent name "A Nozzle Ventilation Detection Device" describes a technical solution that includes "a frame, a vibratory plate, a central plate, and a feeding channel; the vibratory plate is symmetrically arranged on both sides of the frame, the central plate is located on the upper surface of the frame, the vibratory plate is movably connected to the central plate through a feeding channel, the feeding channel includes a qualified product channel and a defective product channel, and the feeding channel corresponds to the position of the central plate; it also includes a drive mechanism, a ventilation detection mechanism, a material blocking mechanism, and a central air blowing mechanism; the drive mechanism is located inside the frame, and the ventilation detection mechanism, the material blocking mechanism, and the central air blowing mechanism are all located on the upper surface of the frame."

[0004] However, when the ventilation detection mechanism is driven by the drive mechanism to detect the nozzle, the flexible sealing block at the top of the air supply block pushes the nozzle out of the material tank during the process of the lifting drive rod driving the connecting plate and the arc-shaped lifting plate to rise. This prevents the flexible sealing block from being inserted into the nozzle, resulting in a gap between the flexible sealing plug and the nozzle. As a result, when air is supplied through the air supply block, gas leaks between the flexible sealing block and the air supply block, making it impossible to effectively detect the nozzle. This not only reduces the air supply sealing performance during nozzle detection but also reduces the detection effect of the nozzle.

[0005] Therefore, in order to solve the above-mentioned technical problems, this utility model proposes a nozzle detection device to improve the air supply sealing performance. Utility Model Content

[0006] The main purpose of this invention is to provide a nozzle detection device that improves the air supply sealing performance, which can effectively solve the problems in the background art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A nozzle detection device for improving air supply sealing includes a frame. An indexing plate is fixedly connected to the top surface of the frame, and a material tray is fixedly connected to the top surface of the indexing plate. The top surface of the material tray has several material grooves, and nozzle bodies are placed in the grooves. A nozzle detection mechanism is provided on the top surface of the frame and on one side of the material tray. The nozzle detection mechanism includes a concave frame, a first cylinder, a pressure plate, a second cylinder, a wedge plate, a lifting shaft, a base, a triangular plate, and an air supply seat. The concave frame is fixedly connected to the top surface of the frame, and the first cylinder is fixed... The first cylinder is fixedly connected to the output end of the concave frame, and the second cylinder is fixedly connected to the rear wall of the concave frame. A wedge plate is fixedly connected to the output end of the second cylinder. The lifting shaft is movably connected to the linear bearing on the top surface of the fixed plate inside the concave frame. The chassis is fixedly connected to the top of the lifting shaft. The triangular plate is fixedly connected to the bottom surface of the chassis. A compression spring is sleeved on the outside of the lifting shaft and fixedly connected between the chassis and the linear bearing. The air supply seat is fixedly connected to the top of the lifting shaft.

[0009] Furthermore, the concave frame is fixedly installed on the top surface of the machine frame and located on one side of the material tray, and a fixing plate is fixedly installed on the inner side wall of the concave frame, and a linear bearing is inserted and fixedly installed in the top surface of the fixing plate.

[0010] Furthermore, a transverse sliding groove is provided on the bottom surface of the concave frame, and a vertical sliding opening is provided on the side wall of the vertical part of the concave frame. The first cylinder is fixedly installed on the top surface of the concave frame, and a pressure plate is fixedly installed on the output end of the first cylinder. A slider is fixedly installed on the side wall of the pressure plate, and the slider is movably installed in the vertical sliding opening.

[0011] Furthermore, the second cylinder is fixedly installed at the bottom of the side wall of the concave frame, and a wedge plate is fixedly installed on the output end of the second cylinder. A slide bar is fixedly installed on the bottom surface of the wedge plate, and the slide bar is movably installed in the transverse slide groove.

[0012] Furthermore, the lifting shaft is inserted into the linear bearing, and a chassis is fixedly installed at the bottom end of the lifting shaft. A triangular plate is fixedly installed on the bottom surface of the chassis, and a compression spring is sleeved on the outside of the lifting shaft and fixedly installed between the opposing walls of the chassis and the linear bearing. An air supply seat is also fixedly installed at the top end of the lifting shaft.

[0013] Furthermore, an air supply pipe is fixedly installed on the input end of the side wall of the air supply base, and an air flow meter is fixedly installed between the air supply pipes. An air nozzle is fixedly installed on the output end of the top surface of the air supply base, and a connecting air supply channel is opened between the input end and the output end of the air supply base. A fixing ring is also fixedly installed at the top of the air outlet of the air nozzle, and a sealing ring is fixedly installed inside the fixing ring.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In this invention, the nozzle detection mechanism works as follows: when the indexing plate rotates the material tray to position the nozzle body in the material trough to the detection position, the first cylinder pushes the pressure plate downwards to press the nozzle body into the material trough, and the second cylinder pushes the wedge plate upwards to compress the triangular plate and push the base plate upwards, forcing the compression spring to tighten. Then, the lifting shaft pushes the air supply seat upwards, causing the suction end of the nozzle body to insert into the sealing ring installed inside the fixing ring. The sealing ring is then pressed tightly against the lower surface of the material tray. Through the elastic deformation of the sealing ring, the suction end of the nozzle body is sealed to the air nozzle. At this time, the nozzle body installed in the air supply... The gas supply pipe at the gas inlet end introduces gas into the gas supply channel within the gas supply pipe. The gas passes through the air flow meter before entering the gas supply channel. Therefore, the gas is ejected through the nozzle installed on the output end and enters the nozzle body through the suction end of the nozzle body before being ejected. In this process, the gas pressure and flow rate ejected from the nozzle body can be accurately detected to determine whether the gas flow rate ejected from the nozzle body meets the design requirements, thereby detecting whether the nozzle body is qualified. This effectively detects the nozzle body and avoids gas leakage during detection. It not only improves the gas supply sealing during nozzle body detection but also improves the detection effect and accuracy of the nozzle body. Attached Figure Description

Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0024] like Figure 1 - Figure 5 As shown, a nozzle detection device for improving air supply sealing includes a frame 1. A dividing plate 2 is fixedly connected to the top surface of the frame 1, and a material tray 3 is fixedly connected to the top surface of the dividing plate 2. The top surface of the material tray 3 has several material grooves 4, and nozzle bodies 5 are placed in the grooves 4. A nozzle detection mechanism 6 is provided on the top surface of the frame 1 and on one side of the material tray 3. The nozzle detection mechanism 6 includes a concave frame 7, a first cylinder 12, a pressure plate 13, a second cylinder 15, a wedge plate 16, a lifting shaft 18, a base 19, a triangular plate 20, and an air supply seat 22. The concave frame 7 is fixedly connected to the top surface of the frame 1, and the first cylinder 12... The first cylinder 12 is fixedly connected to the top surface of the concave frame 7. The output end of the first cylinder 12 is fixedly connected to the pressure plate 13. The second cylinder 15 is fixedly connected to the rear wall of the concave frame 7. The wedge plate 16 is fixedly connected to the output end of the second cylinder 15. The lifting shaft 18 is movably connected to the linear bearing 9 on the top surface of the fixed plate 8 inside the concave frame 7. The chassis 19 is fixedly connected to the top of the lifting shaft 18. The triangular plate 20 is fixedly connected to the bottom surface of the chassis 19. The compression spring 21 is sleeved on the outside of the lifting shaft 18 and fixedly connected between the chassis 19 and the linear bearing 9. The air supply seat 22 is fixedly connected to the top of the lifting shaft 18.

[0025] like Figure 3 As shown, the concave frame 7 is fixedly installed on the top surface of the frame 1 and located on one side of the material tray 3. A fixing plate 8 is fixedly installed on the inner side wall of the concave frame 7. A linear bearing 9 is inserted and fixedly installed in the top surface of the fixing plate 8. The linear bearing 9 is used to cooperate with the lifting shaft 18 to realize linear up and down movement operation.

[0026] like Figure 3 and Figure 4 As shown, a transverse sliding groove 10 is provided on the bottom surface of the concave frame 7. The transverse sliding groove 10 is used to cooperate with the slide bar 17 to achieve sliding operation. A vertical sliding opening 11 is provided on the side wall of the vertical part of the concave frame 7. The first cylinder 12 is fixedly installed on the top surface of the concave frame 7, and a pressure plate 13 is fixedly installed on the output end of the first cylinder 12. A slider 14 is fixedly installed on the side wall of the pressure plate 13, and the slider 14 is movably installed in the vertical sliding opening 11. When the first cylinder 12 is turned on to drive the output end to push the pressure plate 13 downward, the slider 14 on the side wall of the pressure plate 13 will slide in the vertical sliding opening 11 until the pressure plate 13 presses the nozzle body 5 on the material tray 3 to be tested into the groove of the material trough 4. This can avoid the problem of the nozzle body 5 being pushed out of the material trough 4 when testing the nozzle body 5.

[0027] like Figure 4 As shown, the second cylinder 15 is fixedly installed at the bottom of the side wall of the concave frame 7, and a wedge plate 16 is fixedly installed on the output end of the second cylinder 15. A slide bar 17 is fixedly installed on the bottom surface of the wedge plate 16, and the slide bar 17 is movably installed in the transverse slide groove 10. When the second cylinder 15 is turned on, the output end of the drive cylinder pushes the wedge plate 16, and the slide bar 17 on the bottom surface of the wedge plate 16 will slide in the transverse slide groove 10. The wedge plate 16 can provide a lifting driving force for the lifting shaft 18.

[0028] like Figure 4 As shown, the lifting shaft 18 is inserted into the linear bearing 9, and a chassis 19 is fixedly installed at the bottom end of the lifting shaft 18. A triangular plate 20 is fixedly installed on the bottom surface of the chassis 19, and a compression spring 21 is fitted on the outside of the lifting shaft 18 and fixedly installed between the opposing walls of the chassis 19 and the linear bearing 9. An air supply seat 22 is also fixedly installed at the top end of the lifting shaft 18. When the wedge plate 16 pushes forward, it will press the triangular plate 20 upward, causing the triangular plate 20 to push the chassis 19 upward, forcing the compression spring 21 to tighten. This causes the lifting shaft 18 to move upward along the linear bearing 9 and push the air supply seat 22 to move upward. After the wedge plate 16 stops pressing the compression spring 21, the reverse restoring force of the compression spring 21 can drive the air supply seat 22 to move downward and reset through the lifting shaft 18, in preparation for the next operation.

[0029] like Figure 4 and Figure 5As shown, an air supply pipe 23 is fixedly installed on the input end of the side wall of the air supply base 22, and an air flow meter 24 is fixedly installed between the air supply pipes 23. An air nozzle 26 is fixedly installed on the output end of the top surface of the air supply base 22, and a connecting air supply channel 25 is opened between the input end and the output end of the air supply base 22. A fixing ring 27 is also fixedly installed at the top of the air outlet of the air nozzle 26, and a sealing ring 28 is fixedly installed inside the fixing ring 27. When the air supply base 22 moves upward, it will force the suction end of the nozzle body 5 at the bottom to be inserted into the sealing ring 28 inside the fixing ring 27. After the sealing ring 28 undergoes elastic deformation, it will exert pressure on the nozzle body 5. The suction end is sealed. At this time, air can be supplied to the air supply channel 25 through the air supply pipe 23 connected to the external air supply source on the input end. When the air is supplied, the gas will pass through the air flow meter 24. After the gas passes through the air flow meter 24 and enters the air supply channel 25, it will be sprayed out through the air outlet of the air nozzle 26 installed on the output end. The sprayed gas will enter the nozzle body 5 through the suction end of the air supply channel 25 in the sealed space and be sprayed out. At this time, the air pressure and air flow rate of the nozzle body 5 can be detected by the air flow meter 24 to determine whether the flow rate of the nozzle body meets the design requirements and whether the nozzle body 5 is qualified.

[0030] The specific detection principle of the nozzle body 5 by the nozzle detection mechanism 6 is as follows:

[0031] After production, the nozzle body 5 is fed into the material trough 4 on the top surface of the material tray 3 by the feeding equipment. The material tray 3 will rotate under the drive of the indexing plate 2. When the material tray 3 rotates and positions the nozzle body 5 in the material trough 4 to the nozzle detection mechanism 6, the first cylinder 12 installed on the top surface of the concave frame 7 is activated. The first cylinder 12 will drive the output end to push the pressure plate 13 downward. The slider 14 on the side wall of the pressure plate 13 will slide in the vertical sliding opening 11 on the side wall of the concave frame 7 until the pressure plate 13 presses and fixes the nozzle body 5 in the material trough 4. This ensures that the nozzle body 5 is prevented from shifting during the detection of the nozzle body 5, which would lead to inaccurate detection. Then, the second cylinder 15 installed on the side wall of the concave frame 7 is activated. 15 will drive the output end to push the wedge plate 16. The slide bar 17 on the bottom surface of the wedge plate 16 will slide in the transverse slide groove 10 opened on the bottom surface of the nozzle body 5. During the movement, the wedge plate 16 will push the inclined surface to press against the inclined surface of the triangular plate 20 installed on the bottom surface of the chassis 19, so that the triangular plate 20 is forced to move upward after being compressed. The triangular plate 20 will push the chassis 19 to move upward, and force the compression spring 21, which is fitted outside the lifting shaft 18 and fixed between the linear bearing 9 and the chassis 19, to retract. The chassis 19 will push the lifting shaft 18 to move upward along the linear bearing 9 installed on the top surface of the fixed plate 8. The air supply seat 22 installed at the top of the lifting shaft 18 will move upward and gradually approach the nozzle body. The suction end of the nozzle body 5 is inserted into the sealing ring 28 inside the fixing ring 27 at the top of the nozzle 26. After the sealing ring 28 undergoes elastic deformation, it wraps and seals the suction end of the nozzle body 5. At the same time, the sealing ring 28 will press against the lower surface of the material tray 3 to prevent gas leakage during detection. At this time, the external air supply source is turned on and high-pressure gas is introduced into the air supply base 22 from the input end through the air supply pipe 23. When the high-pressure gas enters the air supply channel 25, it will pass through the air flow meter 24. The high-pressure gas entering the air supply channel 25 will enter the nozzle 26 installed on the output end and be sprayed out at the output end of the nozzle 26. Finally, the high-pressure gas sprayed out through the nozzle 26 will... Under sealing, air enters the nozzle body 5 through the suction end at the bottom, which serves as the vent. During the airflow process, the air pressure and flow rate of the nozzle body 5 are monitored by the airflow meter 24 to determine if the flow rate meets design requirements. By checking if the flow rate is greater than or less than the preset value of the airflow meter 24, the condition of the nozzle body 5 can be assessed. This not only improves the air supply sealing during nozzle body 5 testing but also enhances the testing effect and accuracy. After testing the nozzle body 5, the air supply pipe 23 stops supplying air, and the first cylinder 12 drives the output end to move the pressure plate 13 upwards, no longer pressing and fixing the nozzle body 5. Simultaneously…The second cylinder 15 drives the output end to move the wedge plate 16 in the opposite direction. After the wedge plate 16 stops pressing the triangular plate 20, the elastic recovery force of the compression spring 21 pushes the chassis 19, causing the chassis 19 to move the lifting shaft 18 downward along the linear bearing 9 to return to its original position, preparing for the inspection of the next nozzle body 5. The indexing plate 2 then drives the material tray 3 to rotate, positioning the next nozzle body 5 at the nozzle inspection mechanism 6 for inspection. This process is repeated continuously to inspect the nozzle bodies 5 until all nozzle bodies 5 have been inspected.

[0032] It should be emphasized that the embodiments described in this utility model are illustrative rather than limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
