Description

Technical Field

[0001] This utility model belongs to the technical field of conveying devices, and in particular relates to a product airtightness testing conveying device. Background Technology

[0002] In the production and quality inspection process of bottled materials (such as pressure vessels), airtightness testing is a crucial step in ensuring product safety, directly impacting the safety during storage, transportation, and use, and preventing media volatilization, contamination, or safety accidents caused by leaks. However, current industry practices for airtightness testing of bottled materials still face significant technical challenges, severely limiting testing efficiency and accuracy. Specific issues are as follows:

[0003] Firstly, the inconsistent orientation of materials leads to difficulties in testing alignment. In traditional testing processes, bottled materials are conveyed to the testing station via a conveyor belt. The orientation of the valve inlet is not standardized, requiring manual adjustment to ensure alignment between the inlet and the testing equipment's inflation port. This process is not only labor-intensive but also susceptible to fatigue and operational errors, leading to improper material orientation and subsequent failure to align the inflation port with the valve inlet. This results in testing interruptions or missed detections, while also extending the testing cycle, making it unsuitable for the high-efficiency testing demands of large-scale production.

[0004] Secondly, the equipment has poor adaptability and is difficult to accommodate materials of various specifications. Bottled materials of different batches and models have varying outer diameters. However, in existing conveying and testing devices, the spacing between components used to assist in material positioning or rotation (such as guide wheels and clamping structures) is mostly fixed, making it impossible to flexibly adjust according to the material's outer diameter. When processing materials with larger outer diameters, the fixed spacing easily leads to material compression and deformation; when processing materials with smaller outer diameters, the components may not fit tightly against the bottle body, resulting in slippage during rotation and positioning failure, further reducing production and testing efficiency. Therefore, we propose a product airtightness testing conveying device. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a product airtightness testing and conveying device that allows for the rotation and adjustment of bottle-shaped materials, thereby improving testing and conveying efficiency.

[0006] In view of this, the present invention provides a product airtightness testing conveying device, including a conveyor belt body, a rotating component mounted on the conveyor belt body, the rotating component being used to adjust the rotation of the bottle-shaped material on the conveyor belt body, and an adjusting component being provided at the upper end of the rotating component, the adjusting component being used to adaptively adjust the working distance of the rotating component according to the outer diameter of the bottle-shaped material.

[0007] Furthermore, the rotating assembly includes a support frame disposed on the upper left side of the conveyor belt body. The upper end of the support frame is provided with a sliding groove, and both sides of the lower end of the sliding groove are provided with connecting frames. A rotary motor is disposed on the inner side of the lower end of the connecting frame. A transmission rod is installed at the output end of the rotary motor. A rubber wheel is disposed at the lower end of the transmission rod. A connecting plate is welded to the right side of the connecting frame. A rubber driven wheel is rotatably mounted on the lower end of the connecting plate through a bearing, and the rubber driven wheel is disposed on one side of the rubber wheel.

[0008] Furthermore, a testing frame is provided on the upper right side of the conveyor belt body, and an air inflator is detachably installed in the middle of the upper end of the testing frame, with the air outlet of the air inflator connected to a connecting pipe.

[0009] Furthermore, a sliding rod is welded to the upper end of the connecting frame. The size of the sliding rod is adapted to the size of the sliding groove, and the sliding rod is slidably connected to the sliding groove.

[0010] Furthermore, the rotary motor is detachably connected to the connecting frame by bolts, and the upper end of the rubber wheel is detachably connected to the lower end of the transmission rod by bolts, with the two rubber wheels arranged symmetrically.

[0011] Furthermore, a guide plate is welded to the outside of the connecting frame. The guide plate is located on the left side of the rubber wheel, and the distance between the lower end of the guide plate and the upper end of the conveyor belt body is set to 5 cm.

[0012] Furthermore, the pitch adjustment assembly includes a servo motor mounted on a support frame, a bidirectional lead screw installed at the output end of the servo motor, a lead screw sleeve fixedly installed at the upper end of the connecting frame, the size of the bidirectional lead screw being adapted to the size of the lead screw sleeve, and the bidirectional lead screw and the lead screw sleeve being threadedly connected.

[0013] The beneficial effects of this utility model are:

[0014] The rotating component adjusts the rotation of the bottle-shaped material conveyed on the conveyor belt, ensuring that the valve inlet end of the bottle-shaped material faces the same direction. This eliminates the need for manual adjustment of the material direction, solving problems such as difficulty in detection and missed detection caused by chaotic material orientation in traditional testing. It improves the convenience of subsequent airtightness testing operations and thus increases the efficiency of airtightness testing.

[0015] The adjustable spacing component allows for flexible adjustment of the working distance of the rotating component based on the outer diameter of the bottle-shaped material. This ensures that the rotating component always maintains a stable fit with the outer wall of the bottle, effectively preventing slippage and adjustment failures caused by differences in material size. Consequently, it improves the stability of the rotating component in adjusting the rotation of bottle-shaped materials of different specifications, broadens the adaptability of the device to different batches and models of bottle-shaped materials, and reduces the cost of equipment replacement or modification.

[0026] Reference Figures 1 to 3 The product airtightness testing conveying device includes a conveyor belt body 1, on which a rotating component is mounted. The rotating component is used to adjust the rotation of the bottle-shaped material on the conveyor belt body 1. An adjustment component is provided at the upper end of the rotating component. The adjustment component adaptively adjusts the working distance of the rotating component according to the outer diameter of the bottle-shaped material.

[0027] This application uses the circulating transmission belt of the conveyor body 1 to transport the bottled material to be tested from the feeding end to the testing end, providing basic conveying power for the entire process. When the material is transported to the area where the rotating component is located, the rotating component starts and contacts the bottle body. Through mechanical force (friction), the material is driven to rotate around its own axis. During the rotation, through a preset positioning and recognition mechanism (photoelectric sensor identifies the position of the valve air inlet), the valve air inlets of all materials are finally adjusted to a uniform orientation (facing directly in front of the testing end), completing the standardization of material orientation. At the same time, the spacing adjustment component adjusts the distance between the parts in contact with the material in the rotating component through the internal drive structure, ensuring that the rotating component can always fit tightly against the outer wall of the bottle body, regardless of the outer diameter of the material. This avoids the problem of insufficient rotation due to excessive spacing or material compression and deformation due to insufficient spacing, and finally prepares for the subsequent air inlet docking for air tightness testing.

[0028] In the example of this application, the rotating component includes a support frame 13 disposed on the upper left side of the conveyor belt body 1. The upper end of the support frame 13 is provided with a slide groove 14. Both sides of the lower end of the slide groove 14 are provided with connecting frames 23. The lower inner side of the connecting frame 23 is provided with a rotary motor 2. The output end of the rotary motor 2 is equipped with a transmission rod 21. The lower end of the transmission rod 21 is provided with a rubber wheel 22. A connecting plate 4 is welded to the right side of the connecting frame 23. The lower end of the connecting plate 4 is rotatably mounted with a rubber driven wheel 5 through a bearing. The rubber driven wheel 5 is disposed on one side of the rubber wheel 22.

[0029] As a preferred example of this utility model, the support frame 13 is fixed to both sides of the conveyor belt body 1 by bolts, forming a stable frame structure, providing an installation reference for components such as the connecting frame 23 and the rotary motor 2. The sliding groove 14 opened at its upper end provides space for the movement of the connecting frame 23. The two connecting frames 23 are respectively installed on both sides of the support frame 13, and a rotary motor 2 is fixed to the inner side of the lower end of each connecting frame 23. The output shafts of the two rotary motors 2 rotate in the same direction and have the same speed (controlled synchronously by circuit). After the rotary motor 2 is powered on, the torque at the output end is transmitted to the rubber wheel 22 through the transmission rod 21, driving the rubber wheel 22. The rubber wheels 22 rotate at the same speed and in the same direction. When the bottled material is conveyed by the conveyor belt to the space between the rubber wheels 22 and the driven rubber wheel 5, the conveyor belt stops conveying. The outer circumferential surface of the rubber wheels 22 is in close contact with the outer wall of the bottle. Due to the friction between the rubber wheels 22 and the bottle, the rotation of the rubber wheels 22 is converted into the rotational power of the bottle through friction, which drives the material to rotate around its own axis. At the same time, the symmetrically arranged rubber wheels 22 apply a balanced force from both sides of the material to prevent the material from deviating to one side during rotation, ensuring a stable rotation trajectory until the air inlet end of the material valve reaches the preset orientation.

[0030] In the example of this application, a detection frame 11 is provided on the upper right side of the conveyor belt body 1, and an air inflator 12 is detachably installed on the upper middle part of the detection frame 11. The air outlet of the air inflator 12 is connected to a connecting pipe 15.

[0031] As a preferred example of this utility model, the testing frame 11 is fixed to the upper right side of the conveyor belt body 1. The distance between its installation position and the left rotating component is calculated and designed to ensure that bottle-shaped materials, after rotation adjustment and with the air inlet facing the same direction, can be directly conveyed by the conveyor belt to the area directly below the testing frame 11. Furthermore, the air inlet valve of the material is precisely aligned with the connecting pipe 15 of the air inflator 12 on the testing frame 11, eliminating the need for additional material position adjustments. When the material reaches the testing position, the air inflator 12 starts, and its internal air pump generates gas at a preset pressure (high or low pressure is set according to testing requirements). The gas then flows through... The gas is delivered through the connecting pipe 15 at the outlet to the valve inlet of the material (the port of the connecting pipe 15 and the valve inlet are connected by a sealing joint to ensure airtightness); after the gas is injected into the material, the inflator 12 monitors the pressure change inside the material in real time through a pressure sensor. If the pressure remains stable, it indicates that the material is airtight; if the pressure drops, it indicates that there is a leak, thus completing the airtightness test; when it is necessary to change to a test with different pressure specifications, it is only necessary to remove the bolts connecting the inflator 12 and the test frame 11 to replace the corresponding inflator 12 without modifying other structures of the test frame 11.

[0032] In the example of this application, a slide rod 24 is welded to the upper end of the connecting frame 23. The size of the slide rod 24 is adapted to the size of the slide groove 14, and the slide rod 24 is slidably connected to the slide groove 14.

[0033] As a preferred example of this utility model, when the pitch adjustment component drives the connecting frame 23 to move to adjust the pitch, the slide bar 24 slides synchronously along the direction of the slide groove 14. The slide groove 14 restricts the lateral displacement of the slide bar 24, preventing the connecting frame 23 from shifting back and forth or swaying up and down during the movement, ensuring that the connecting frame 23 always moves smoothly in the preset direction, thereby ensuring that the components such as the rotary motor 2 and the rubber wheel 22 installed on the connecting frame 23 can accurately adjust the pitch. At the same time, the welding connection between the slide bar 24 and the connecting frame 23 forms an integrated structure that can withstand the driving force applied by the pitch adjustment component during the pitch adjustment process, as well as the reaction force generated on the rubber wheel 22 when the material rotates, preventing the slide bar 24 from separating from the connecting frame 23 and causing structural failure, thus ensuring the stability and safety of the entire adjustment process.

[0034] In the example of this application, the rotary motor 2 is detachably connected to the connecting frame 23 by bolt fixing, the upper end of the rubber wheel 22 is detachably connected to the lower end of the transmission rod 21 by bolt fixing, and the two rubber wheels 22 are symmetrically arranged.

[0035] As a preferred example of this utility model, when the rotary motor 2 malfunctions, the motor can be removed for repair or replacement simply by unscrewing the bolts securing it, without needing to disassemble other components such as the connecting frame 23 and the transmission rod 21. Similarly, when the rubber wheel 22 wears down due to long-term friction, it can be removed and replaced separately, greatly simplifying maintenance. At the same time, the two rubber wheels 22 maintain a symmetrical distribution under the drive of the transmission rod 21 (with the material's central axis as the center of symmetry). When rotating, the frictional forces applied to the material bottle are equal in magnitude and opposite in direction, ensuring that the material is balanced in the horizontal direction. This prevents the material from shifting or tipping to one side due to excessive friction on one side, ensuring that the material can rotate stably around its own axis. After replacing the rubber wheel 22, the symmetrical drive state can be quickly restored by simply adjusting the wheel position according to the symmetry reference, ensuring consistent rotation.

[0036] In the example of this application, a guide plate 3 is welded to the outside of the connecting frame 23. The guide plate 3 is located on the left side of the rubber wheel 22, and the distance between the lower end of the guide plate 3 and the upper end of the conveyor belt body 1 is set to 5 cm.

[0037] As a preferred example of this utility model, the guide plate 3 is welded to the outside of the connecting frame 23 and located to the left of the rubber wheel 22. Its plate surface is inclined (extending outward on the side near the edge of the conveyor belt and contracting inward on the side near the rubber wheel 22), forming a gradually narrowing guide channel. When the bottle-shaped material is conveyed to the area of ​​the guide plate 3 by the conveyor belt, if the material position is biased towards the edge of the conveyor belt, it will first contact the inclined plate surface of the guide plate 3. The guide plate 3 generates a lateral thrust on the material, guiding the material towards the middle of the conveyor belt (the position of the rubber wheel 22), avoiding the material from being unable to enter between the two rubber wheels 22 due to positional deviation. This ensures that the material can only be conveyed forward along the channel formed by the guide plate 3, and finally accurately enters the adjustment area between the two rubber wheels 22. The pre-positioning of the material can be completed without manual intervention.

[0038] In the example of this application, the pitch adjustment component includes a servo motor 26 mounted on a support frame 13. A bidirectional lead screw 27 is mounted on the output end of the servo motor 26. A lead screw sleeve 25 is fixedly mounted on the upper end of the connecting frame 23. The size of the bidirectional lead screw 27 is adapted to the size of the lead screw sleeve 25, and the bidirectional lead screw 27 is threadedly connected to the lead screw sleeve 25.

[0039] As a preferred example of this utility model, the two ends of the bidirectional lead screw 27 are machined with threads of opposite directions (left-hand thread on the left and right-hand thread on the right), and both ends respectively engage with the lead screw sleeves 25 on the upper ends of the two connecting frames 23 (the lead screw sleeve 25 of the left connecting frame 23 matches the left-hand thread, and the lead screw sleeve 25 of the right connecting frame 23 matches the right-hand thread); when it is necessary to adjust the distance between the rubber wheels 22 according to the outer diameter of the material, the servo motor 26 starts after receiving the control signal, and the output end drives the bidirectional lead screw 27 to rotate, thereby driving the two connecting frames 23 to move synchronously towards or away from each other, realizing the adjustment of the distance between the rubber wheels 22; the servo motor 26 has a built-in winding mechanism. The encoder can provide real-time feedback on the motor rotation angle, and the control system can calculate and precisely control the number of rotations of the bidirectional lead screw 27, thereby accurately adjusting the spacing (adjustment accuracy can reach the millimeter level). At the same time, the threaded connection between the bidirectional lead screw 27 and the lead screw sleeve 25 has a self-locking characteristic (the thread helix angle is less than the friction angle). When the servo motor 26 stops working, the lead screw sleeve 25 will not move on its own due to the reaction force or vibration of the material, ensuring that the spacing is stably maintained at the set value without the need for an additional locking device. The entire adjustment process is automatically triggered by the material size parameters preset by the control system, without the need for manual operation, realizing rapid switching and adjustment of multiple specifications of materials.

[0040] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
