Description

Technical Field

[0001] This utility model belongs to the field of infusion soft bag detection technology, and specifically relates to a high-voltage leak detector for infusion soft bags. Background Technology

[0002] Infusion bags consist of a bag body and a tube opening. The bag body is formed by heat-sealing overlapping plastic films around its outer perimeter, while the tube opening is formed by welding a plastic tube wrapped in film. During the manufacturing process of infusion bags, micropores may exist at any point in the bag body or the tube opening. When micron-level micropores appear, they are difficult to detect accurately using conventional methods such as immersion or pressure attenuation, easily leading to missed detections. High-voltage discharge leak detection equipment can effectively solve this problem. Through high-voltage detection technology, it can quickly locate micron-level pores, improve detection accuracy, and ensure the quality of infusion bags. However, existing high-voltage discharge leak detection equipment requires mounting a high-voltage detection motor on an inclined conveyor belt. The infusion bag rises and falls with the conveyor belt via a bag-pressing device. This rising and falling movement causes air bubbles inside the bag to move, allowing for leak detection at different locations. This detection method has a complex overall equipment structure, long conveying distance, and high friction between the bag body and the conveyor belt during transport, posing a greater risk of bag wear and affecting the quality of the infusion bag. In addition, most existing high-voltage discharge leak detection equipment uses a brush-type high-voltage emitter and a thin-film receiver. The end of the high-voltage emitter is narrow or needle-shaped. During detection, both the end of the high-voltage emitter and the receiver need to contact the surface of the infusion bag to form a capacitor structure. Therefore, the end of the high-voltage emitter is prone to scratching the surface of the infusion bag. Especially when the film of the bag is thin, it is very easy to create new leakage points in the infusion bag, which will damage the quality of the infusion bag and cause new defects or missed detections. Utility Model Content

[0003] The purpose of this invention is to propose a high-voltage leak detector for infusion bags, in order to solve the problems that existing high-voltage discharge leak detection equipment relies on sloping conveyor belts for detection, and that the detection electrodes can easily damage the quality of infusion bags, creating new quality risks.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model proposes a high-voltage leak detector for infusion soft bags, which includes a multi-segment conveyor belt. The conveyor belt includes an independently set inlet segment, a detection segment and an outlet segment. The outlet segment is equipped with a rejection device, and the detection segment is equipped with multiple leak detection devices. The infusion soft bag passes through each group of leak detection devices in sequence on the conveyor belt.

[0006] The detection section is horizontally set and internally divided into multiple independent conveying sections. The infusion bag is placed horizontally on the conveyor belt for horizontal conveying.

[0007] The leak detection device comprises at least two sets, which are arranged sequentially along the detection section. The leak detection device includes a first leak detection device and a second leak detection device. The first leak detection device is located in the gap between the inlet section and the detection section and is used to detect the leakage points at the edge of the infusion soft bag and the tube opening. The second leak detection device is located in the gap between the delivery sections within the detection section and is used to detect the leakage points in the body of the infusion soft bag.

[0008] Both the first and second leak detection devices include an emitter and a receiver. The emitter is mounted above the conveyor belt. The emitter of the first leak detection device is a comb-shaped electrode brush, which is positioned close to both sides of the conveyor belt, with its end contacting the edge and opening of the infusion bag. The emitter of the second leak detection device is a brush-shaped electrode, which is composed of multiple layers of bundled filament single electrodes. The brush-shaped electrode is positioned centrally relative to the conveyor belt, with its end suspended above the body of the infusion bag. The receiver is located between the conveyor belts and is a thin-film electrode. The upper surface of the receiver is flush with the upper surface of the conveyor belt and in contact with the surface of the infusion bag.

[0009] The conveyor belt is equipped with photoelectric sensors at the installation points of the first and second leak detection devices, which are used to detect the position of the infusion bag and control the opening and closing of the first and second leak detection devices.

[0010] Based on the above technical solutions, by setting the detection section to be horizontal and distinguishing between detection devices for the edges, tube openings, and bag body of the infusion soft bag, comb-shaped electrode brushes are used for contact detection in areas such as the edges and tube openings that are thicker and more prone to significant leaks, ensuring detection accuracy. In areas of the bag body where the film thickness is small and prone to micron-level leaks, brush-shaped electrodes are used for dense non-contact detection. The infusion soft bag is formed into a dense series-parallel microcapacitor combination, which ensures that the bag body quality is not damaged and that detection accuracy is guaranteed. It can also weaken or even eliminate the interference of air bubbles. The device has the characteristics of simple overall structure, high detection accuracy, and effective detection of micropores.

[0011] Preferably, the brush-shaped electrode has no fewer than 5 layers. The purpose of this design is to increase the number of microcapacitors formed by the infusion bag, so as to ensure that the leak detection equipment has sufficient detection accuracy.

[0012] Preferably, the distance between the end of the brush-shaped electrode and the surface of the infusion bag is 1-3 mm. The purpose of this design is to form an effective high-voltage ionization field between the emitter and receiver, so that the infusion bag forms a capacitor structure, thereby ensuring the detection effect.

[0013] Preferably, the second leak detection device has two brush-shaped electrodes, which are symmetrically arranged relative to the receiving electrode. The purpose of this design is to form dispersed detection points, avoid large-area concentrated high-voltage discharge leading to high air ionization, thereby reducing the generation of ionized pollutants. At the same time, it can improve the detection coverage, relatively reduce the number of electrodes used, and help save costs.

[0014] Preferably, the mounting frame includes a support, a mounting base, a crossbar, and an electrode mounting block. The support is fixed to both sides of the conveyor belt. The mounting base is adjustable and height-adjustable on the support. The mounting base has a strip-shaped through hole. The crossbar is mounted above the conveyor belt, and its two ends are respectively embedded in the strip-shaped through hole for fixation. The electrode mounting block is mounted on the crossbar and is used to install the emitter. This design facilitates the adaptation of the leak detection device to conveyor bags of different specifications, improves the overall applicability of the equipment, and enhances the ease of electrode adjustment.

[0015] More preferably, the electrode mounting block is rotatably mounted relative to the crossbar, and the emitter can be tilted inward or outward relative to the vertical direction. This design facilitates the adaptation to different specifications of testing by adjusting the tilt angle, and further simplifies the electrode adjustment operation when changing different products.

[0016] Preferably, the inlet section of the conveyor belt is equipped with a bag stacking detection mechanism. The bag stacking detection mechanism includes a fixed base, a support rod, and a detection rod. The fixed base is located on one side of the conveyor belt. One end of the support rod is rotatably connected to the upper end of the fixed base, and the other end extends above the conveyor belt. Two detection rods are provided on the support rod. A teardrop-shaped gravity block is provided at the lower end of the detection rod. The distance between the gravity block and the upper surface of the conveyor belt is slightly greater than the flat height of a single infusion bag. The bag stacking detection mechanism is signal-connected to the detection section. When the infusion bags are stacked, the detection rod is swung upward, and the bag stacking detection mechanism controls the detection section to stop moving. This design helps to effectively prevent abnormalities such as electrode damage, infusion bag damage, and detection fault errors caused by bag stacking, thereby improving detection efficiency.

[0017] More preferably, the inlet section is further provided with a de-stacking mechanism behind the bag-stacking detection mechanism. The de-stacking mechanism is an automatic lifting crossbar mounted above the inlet section. The de-stacking mechanism is signal-connected to the bag-stacking detection mechanism. When the bag-stacking detection mechanism detects a stacked bag, the automatic lifting crossbar moves down to a position close to the square height of the single-layer infusion soft bag, pushing the upper infusion soft bag to slide onto the inlet section. This design helps to avoid production line stoppages caused by bag stacking, solving the bag stacking problem while ensuring production continuity.

[0018] More preferably, a telescopic rod is also provided on the side of the inlet section. The telescopic rod is connected to a time-delay relay. When the automatic lifting crossbar descends, the telescopic rod extends after the delay ends, preventing the upper infusion bag from sliding down and moving with the lower infusion bag, thereby increasing the distance between the two and avoiding false alarms or interference during detection.

[0019] Preferably, the entire detection section is equipped with a protective cover, and the leak detection devices are all located inside the protective cover. A negative pressure suction port is provided below the detection section, and the suction port is connected to the ozone purification system. The purpose of this design is to quickly purify pollutants such as ozone generated by ionization, so as to avoid polluting the production environment and the external environment.

[0020] More preferably, an activated carbon filter is provided between the suction port and the ozone purification system to adsorb fine solid particles generated by ionization. This design can extend the service life of the ozone purification system and reduce the maintenance frequency.

[0021] Beneficial effects

[0022] One of the above technical solutions has the following advantages or beneficial effects:

[0023] 1) By setting the detection section to horizontal and distinguishing between the detection devices for the edges, tube openings, and bag body of the infusion soft bag, comb-shaped electrode brushes are used for contact detection in areas such as the edges and tube openings that are thicker and more prone to significant leaks, ensuring detection accuracy. Brush-shaped electrodes are used for dense non-contact detection in areas of the bag body where the film thickness is small and micron-level leaks are prone to occur. This makes the infusion soft bag a combination of dense series and parallel microcapacitors, ensuring that the bag body quality is not damaged and that detection accuracy is guaranteed. It can also weaken or even eliminate the interference of air bubbles. The device has the characteristics of simple overall structure, high detection accuracy, and effective detection of micropores.

[0024] 2) The adjustable mounting base with adjustable horizontal and vertical distances and the rotatable and adjustable emitter angle make the equipment compatible with soft bags of different specifications, improving the overall applicability of the equipment and the convenience of electrode adjustment.

[0025] 3) The bag stacking detection mechanism and de-stacking mechanism at the inlet section can effectively prevent abnormalities such as electrode damage, infusion soft bag damage and detection faults caused by bag stacking, which helps to improve detection efficiency and ensure the quality and reliability of infusion soft bags.

[0033] The present invention will be further described in detail below with reference to the embodiments, but the implementation of the present invention is not limited thereto.

[0034] like Figure 1 As shown, this utility model provides a high-voltage leak detector for infusion bags, including a multi-segment conveyor belt 1. Each segment of the conveyor belt 1 includes an independent drive device (not shown in the figure). Each segment of the conveyor belt 1 is provided with several elastic bands 104 for receiving infusion bags. The conveyor belt 1 includes an independently set inlet section 101, a detection section 102, and an outlet section 103. The outlet section 103 is provided with a rejection device (not shown in the figure). The detection section 102 is provided with multiple leak detection devices 2. The infusion bag passes through each set of leak detection devices 2 sequentially on the conveyor belt 1. The inlet section 101, the detection section 102, and the outlet section 103 are all provided with independent elastic bands 104 and elastic bands 104 connecting adjacent conveyor belts 1 to ensure smooth transport of the infusion bag. The leak detection devices 2 are located at positions where the elastic bands 104 are not connected. The conveyor belt 1 and the parts in contact with the leak detection devices 2 are all made of insulating material.

[0035] The detection section 102 is horizontally positioned and internally divided into multiple independent conveying sections. The infusion bag is placed horizontally on the conveyor belt 1 for horizontal conveying, i.e., the bag is conveyed with its opening facing one side of the conveyor belt 1.

[0036] like Figure 1 As shown, the leak detection device 2 consists of at least two sets, arranged sequentially along the detection section 102. The leak detection device 2 includes a first leak detection device 21 and a second leak detection device 22. The first leak detection device 21 is located in the gap between the inlet section 101 and the detection section 102, and is used to detect the leakage points at the edge of the infusion bag and the tube opening. The second leak detection device 22 is located in the gap between the delivery sections within the detection section 102, and is used to detect the leakage points in the body of the infusion bag.

[0037] The first leak detection device 21 and the second leak detection device 22 both include an emitter 201 and a receiver 202. The emitter 201 and the receiver 202 are respectively connected to the two ends of a high-voltage power supply (not shown in the figure) to form a high-voltage discharge circuit. The emitter 201 is mounted above the conveyor belt 1 through the mounting bracket 3. The receiver 202 is located between the conveyor belts 1 and is a thin-film electrode. The upper surface of the receiver 202 is flush with the upper surface of the conveyor belt 1 and contacts the surface of the infusion bag.

[0038] Among them, such as Figure 2 As shown, the emitter 201 of the first leak detection device 21 is a comb-shaped electrode brush 2011. The comb-shaped electrode brush 2011 is arranged close to both sides of the conveyor belt 1, and its end contacts the edge and tube opening of the infusion soft bag. Preferably, the comb-shaped electrode brush 2011 includes two brushes that are close to each other. The end of the comb-shaped electrode brush 2011 is divided into a plurality of large teeth of equal width. The end of each large tooth is divided into three small teeth at equal intervals. The small teeth contact the edge and tube opening of the infusion soft bag and form a tip discharge in the detection chamber.

[0039] like Figure 3 As shown, the emitter 201 of the second leak detection device 22 is a brush-shaped electrode 2012, which is composed of multiple layers of bundled fine filament single electrodes. This allows high voltage to pass through the emitter 201 to generate a dense tip discharge current, thereby forming a dense series-parallel microcapacitor combination on the body of the infusion bag. This divides the body of the infusion bag into small micro-areas, which can concentrate the current to improve detection accuracy and quickly locate the leak point. Preferably, the number of layers of the brush-shaped electrode 2012 is not less than 5, so as to increase the number of microcapacitors formed by the infusion bag and ensure that the leak detection device has sufficient detection accuracy. The brush-shaped electrode 2012 is centrally positioned relative to the conveyor belt 1, with its end suspended above the body of the infusion soft bag. Preferably, the distance between the end of the brush-shaped electrode 2012 and the surface of the infusion soft bag is 1-3 mm, so as to form an effective high-voltage ionization field between the emitter 201 and the receiver 202, thereby enabling the infusion soft bag to form a capacitor structure and ensuring the detection effect.

[0040] The conveyor belt 1 is equipped with photoelectric sensors 4 at the installation locations of the first leak detection device 21 and the second leak detection device 22, which are used to detect the position of the infusion soft bag and control the opening and closing of the first leak detection device 21 and the second leak detection device 22.

[0041] In a preferred embodiment, the second leak detection device 22 has two brush-shaped electrodes 2012, which are symmetrically arranged relative to the receiving electrode 202 to form dispersed detection points. This avoids high air ionization caused by large-area concentrated high-voltage discharge, thereby reducing the generation of ionized pollutants. At the same time, it can improve the detection coverage, relatively reduce the number of electrodes used, and help save costs.

[0042] As a preferred embodiment, such as Figure 4 As shown, the mounting frame 3 is made of insulating material and includes a support 31, a mounting base 32, a crossbar 33, and an electrode mounting block 34. The support 31 is fixed to both sides of the conveyor belt 1. The mounting base 32 is adjustable and height-adjustable on the support 31. The mounting base 32 has a strip-shaped through hole 321. The crossbar 33 is mounted above the conveyor belt 1 and its two ends are respectively embedded in the strip-shaped through hole 321 for fixation. The electrode mounting block 34 is mounted on the crossbar 33. The electrode mounting block 34 is used to mount the emitter 201. More preferably, the electrode mounting block 34 is rotatable relative to the crossbar 33. The emitter 201 can be tilted inward or outward relative to the vertical direction to adapt to conveyor bags of different specifications, thereby improving the overall applicability of the equipment and the convenience of electrode adjustment.

[0043] As a further implementation method, such as Figure 5 As shown, the inlet section 101 of the conveyor belt 1 is equipped with a bag stacking detection mechanism 5. The bag stacking detection mechanism 5 includes a fixed base 51, a support rod 52, and a detection rod 53. The fixed base 51 is located on one side of the conveyor belt 1. One end of the support rod 52 is rotatably connected to the upper end of the fixed base 51, and the other end extends above the conveyor belt 1. Two detection rods 53 are provided on the support rod 52. A teardrop-shaped gravity block 54 is provided at the lower end of the detection rod 53. The distance between the gravity block 54 and the upper surface of the conveyor belt 1 is slightly larger than the horizontal position of a single infusion bag. The stacking detection mechanism 5 is signal-connected to the detection section 102. When only one layer is being transported, the detection rod 53 remains vertical under the action of the gravity block 54. When the infusion soft bags are stacked, the gravity block 54 is pushed by the upper infusion soft bag, causing the detection rod 53 to swing upward, triggering the stacking signal. The stacking detection mechanism 5 controls the detection section 102 to stop operating, waiting for manual handling of the stacking situation before releasing the bags again. This effectively prevents abnormalities such as electrode damage, infusion soft bag damage, and detection fault errors caused by stacking, thus improving detection efficiency.

[0044] More preferably, to avoid downtime, the inlet section 101 is further provided with a de-stacking mechanism 6 immediately behind the bag-stacking detection mechanism 5. The de-stacking mechanism 6 is an automatic lifting crossbar 61 mounted above the inlet section 101. The de-stacking mechanism 6 is signal-connected to the bag-stacking detection mechanism 5. When the bag-stacking detection mechanism 5 detects a stacked bag, it controls the automatic lifting crossbar 61 to move down to a position close to the square height of the single-layer infusion bag, pushing the upper infusion bag to slide onto the inlet section 101, thereby solving the problem of bag stacking. The automatic lifting crossbar 61 can be automatically controlled to rise and fall by a drive device such as an electric push rod.

[0045] More preferably, the inlet section 101 is also provided with a telescopic rod (not shown in the figure) on the side. The telescopic rod is connected to a time delay relay (not shown in the figure). When the automatic lifting crossbar 61 descends, the telescopic rod extends after the delay ends, preventing the upper infusion bag from sliding down and moving with the lower infusion bag, thereby increasing the distance between the two and avoiding false alarms or interference during detection.

[0046] As a further embodiment, a protective cover 7 is provided around the entire detection section 102, and the leak detection devices 2 are all located inside the protective cover 7. A negative pressure suction port 8 is provided below the detection section 102, and the suction port 8 is connected to an ozone purification system (not shown in the attached figure) to quickly discharge and purify pollutants such as ozone generated by ionization, avoiding pollution of the production environment and the external environment. The protective cover 7 has windows 71 at the inlet and outlet of the detection section 102, forming a complete or partial enclosure of the detection section 102. The protective cover 7 is openable and equipped with an anti-accidental contact device to facilitate maintenance and repair. Preferably, an activated carbon filter is arranged between the suction port 8 and the ozone purification system to adsorb fine solid particles generated by ionization, thereby extending the service life of the ozone purification system.

[0047] Through one or more of the above embodiments, this utility model has the characteristics of simple overall equipment structure, high detection accuracy, high efficiency, effective detection of micropores, safety and environmental protection.

[0048] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
