Description

Technical Field

[0001] The utility model relates to the technical field of air leakage detection equipment, in particular to an air leakage detection device for a packaging line. Background Art

[0002] The packing line refers to the automated production line used in the feed packaging process, which can realize the efficient packaging of feed products. In order to comprehensively control the product quality and ensure that each piece of feed can maintain good sealing during transportation and storage, the feed is usually tested with extrusion-type leakage detection equipment after being packaged on the production line.

[0003] In order to ensure the accuracy of the leakage detection device for the feed packaging bag, it is necessary to transport the feed packaging bag in the center of the conveyor belt so that the packaging bag is aligned with the center of the leakage detection device. At present, some packaging lines can transport the packaging bag in the center through the inclined baffles on both sides of the conveyor belt. However, since the sizes of packaging bags in different batches are different, when adjusting the spacing between the baffles on both sides, it takes multiple attempts or the cooperation of multiple people to make the baffles on both sides tilt synchronously to adapt to the size of the packaging bag, which is inconvenient and inefficient, resulting in poor efficiency and accuracy in the detection of packaging bags;

[0004] At the same time, if the packaging bag leaks, the squeezing operation of the leakage detection device will cause the feed in the packaging bag to spill directly onto the surface of the conveyor belt. The feed powder spilled on the conveyor belt may adhere to the surface of the conveyor belt, which will not only reduce the friction between the conveyor belt surface and the packaging bag, causing the packaging bag to slip during transportation, but also increase the difficulty of subsequent cleaning. In addition, the feed powder on the conveyor belt may be contaminated on the subsequent feed product packaging bags, causing product appearance and hygiene problems. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0024] See also Figure 1-5As shown, a gas leakage detection device for a baling line includes a conveyor belt 1, which includes a motor, a belt body and a driving roller installed in the belt body (the standard configuration of the conveyor belt 1, which are all existing technologies and therefore do not need to be shown in the figure), the motor of the conveyor belt 1 provides power to drive the driving roller to rotate, and the rotating motion of the driving roller of the conveyor belt 1 can transmit power to the belt body through friction, so that the conveyor belt 1 can transport the bagged feed that has been packaged, and the two sides of the conveyor belt 1 are fixedly connected with side panels 2, and the bottom of the side panels 2 is bolted with support legs 3, and the number of support legs 3 is several, and the support legs 3 can provide a stable support effect for the side panels 2, so that the conveyor belt 1 can stably transport the bagged feed away from the ground, and the surface of the side panels 2 is installed with a gas leakage detection device body 14, and the gas leakage detection device body 14 spans above the conveyor belt 1. The gas leakage detection device body 14 can contact and apply a certain pressure to the surface of each feed packaging bag transported by the conveyor belt 1 through its own squeezing roller, and at the same time, a pressure sensor and a gas detector are used to monitor the pressure change and gas leakage of the packaging bag during the squeezing process in real time, and through By analyzing and comparing these data, once a certain packaging bag is found to have pressure drop and gas leakage, the automatic rejection mechanism will be triggered immediately to separate the leaking product from the normal product, thereby ensuring that only qualified feed products are available in the subsequent links, providing reliable protection for the quality and safety of feed products. The surfaces of the side panels 2 on both sides are fixedly connected with support frames 5, which are U-shaped in design, and one side of the opening faces the conveyor belt 1. The inner cavity of the support frame 5 is connected to a baffle 6 through a rotating shaft, and the baffle 6 can guide the feed packaging bags transported on the conveyor belt 1. The side panels 2 on both sides are provided with support shells 7 bolted to the tops thereof, and the inner cavity of the support shells 7 is provided with an adjustment mechanism 8. The adjustment mechanism 8 is used in conjunction with the baffles 6 to synchronously adjust the inclination angles of the baffles 6 on both sides, so as to adapt to guiding feed packaging bags of different sizes, so that feed packaging bags of different sizes can be centered when being conveyed on the surface of the conveyor belt 1;An isolation frame 11 is bolted between the support legs 3, and a collecting box 13 is slidably connected to the lower part of the inner cavity of the isolation frame 11. A guide plate 10 is bolted between the support legs 3 and on one side of the isolation frame 11. The guide plate 10 is designed to be inclined. Larger feed residue particles on the surface of the conveyor belt 1 will fall to the surface of the guide plate 10 as the belt body of the conveyor belt 1 rotates, and then slide along the inclined surface of the guide plate 10 to the inner cavity of the collecting box 13 for unified collection, which can prevent the feed from falling to the ground and affecting the surrounding environment. A cleaning mechanism 4 is provided in the inner cavity of the isolation frame 11. The cleaning mechanism 4 is used in conjunction with the conveyor belt 1 to automatically clean the smaller feed powder adhered to the surface of the conveyor belt 1, prevent the surface of the conveyor belt 1 from accumulating too much feed powder and reducing the friction resistance, thereby reducing its transmission efficiency for subsequent feed packaging bags. A dust suction mechanism 9 is provided on the other side of the inner cavity of the isolation frame 11. The dust suction mechanism 9 can capture and collect the dust generated when the cleaning mechanism 4 cleans the surface of the conveyor belt 1, thereby preventing the feed dust from floating around, which can further reduce the impact on the surrounding environment. ;

[0025] The adjusting mechanism 8 includes a bidirectional screw rod 81, one end of which is rotatably connected to the inner wall of the support shell 7 through a bearing seat, and the other end of the bidirectional screw rod 81 penetrates the outer side of the support shell 7 and is rotatably connected to the inner wall thereof. Both sides of the surface of the bidirectional screw rod 81 are threadedly connected with sliding blocks 82, and the sliding blocks 82 on both sides are symmetrically distributed. The surfaces of the sliding blocks 82 are slidably connected to the inner wall of the support shell 7. A connecting plate 83 is fixed on the top of the baffle 6, and a through groove 84 is provided on the top of the connecting plate 83. The bottom of the sliding block 82 is The bottom of the connecting plate 83 is bolted with a sliding column 85, and the bottom end of the sliding column 85 extends to the bottom of the connecting plate 83 through the through groove 84. The sliding column 85 is slidably connected to the inner wall of the through groove 84. When the bidirectional screw rod 81 rotates, the sliding blocks 82 on both sides of the surface can move toward or away from each other, and the sliding column 85 is slidably connected to the inner wall of the through groove 84, so that the baffles 6 on both sides can be synchronously rotated around the support frame 5 as the center, and the inclination angle of the baffles 6 on both sides can be synchronously adjusted, so that the baffles 6 on both sides can be adjusted. The distance between the two sides of the baffle 6 and the conveyor belt 1 is changed, so that feed packaging bags of different sizes can be conveyed to the leakage detection device body 14 in the center of the surface of the conveyor belt 1 for detection, thereby improving the efficiency and accuracy of the leakage detection of the leakage detection device body 14. An auxiliary component 86 is arranged on one side of the support shell 7. The auxiliary component 86 is used in conjunction with the bidirectional screw rod 81, which is convenient for the staff to rotate the bidirectional screw rod 81, and the bidirectional screw rod 81 is self-locked after it is rotated to prevent it from accidentally rotating, thereby improving the accuracy of the baffle 6 in guiding the feed packaging bag. Rollers 12 are installed on the opposite sides of the baffles 6 on both sides. The number of rollers 12 is several and is equidistantly distributed. When the baffle 6 guides the bagged feed on the conveyor belt 1, the surface of the packaging bag will continuously contact the roller 12. Compared with the guiding method of direct collision of the baffle 6, the rotating roller 12 can guide the packaging bag more gently, reduce scratches and damage to its surface, and can protect the appearance quality of the feed and provide a smoother guiding effect.

[0026] The auxiliary component 86 includes a mounting shell 861, which is fixedly connected to one side of the support shell 7. A worm wheel 863 is bolted to one end of the bidirectional screw 81. A worm 862 is meshedly connected to the surface of the worm wheel 863. One end of the worm 862 is rotatably connected to the inner wall of the mounting shell 861. The other end of the worm 862 penetrates the outer side of the mounting shell 861 and is rotatably connected to the inner wall. A handle is fixedly connected to the other end of the mounting shell 861. The staff can rotate the handle of the worm 862 to make the worm 862 rotate. The rotation of 62 meshes with the worm wheel 863, and the rotating worm wheel 863 can drive the bidirectional lead screw 81 to rotate synchronously. Since the meshing connection between the worm wheel 862 and the worm wheel 863 has a good self-locking effect, after the bidirectional lead screw 81 is rotated, it will not rotate accidentally, and the sliding block 82 and the sliding column 85 will not move easily, and the inclination angle of the baffle 6 will not change easily, thereby improving the stability of the distance adjustment between the baffles 6 on both sides.

[0027] The cleaning mechanism 4 includes a brush roller 41, which is located in the inner cavity of the isolation frame 11. Both ends of the brush roller 41 penetrate to the outer side of the isolation frame 11 and are rotatably connected to the inner wall thereof. A synchronous pulley component 44 is provided at one end of the brush roller 41. The synchronous pulley component 44 includes two synchronous wheels and a synchronous belt. One synchronous wheel of the synchronous pulley component 44 is fixedly connected to one end of the brush roller 41, and the other synchronous wheel of the synchronous pulley component 44 is fixedly connected to one end of the driving roller of the conveyor belt 1, and the synchronous belt of the synchronous pulley component 44 is meshed with the two synchronous wheels. When the driving roller of the conveyor belt 1 rotates, power can be transmitted to the brush roller 41 through the synchronous pulley component 44 to make it rotate. Brush strips are evenly distributed on the surface of the brush roller 41, and the surface of the conveyor belt 1 can be cleaned by the rotational friction of the brush roller 41, and smaller feed powder adhering to the surface of the conveyor belt 1 can be cleaned to prevent excessive feed powder from adhering to the surface of the conveyor belt 1. The other end of the brush roller 41 is bolted to the first gear 42, and a cleaning roller 45 is arranged below the brush roller 41. One end of the cleaning roller 45 is rotatably connected to the inner wall of the isolation frame 11, and the other end of the cleaning roller 45 passes through the outside of the isolation frame 11 and is rotatably connected to the inner wall thereof. The other end of the cleaning roller 45 is bolted to the second gear 43, and the second gear 43 is meshed with the first gear 42. A cleaning strip made of nylon is fixed to the surface of the cleaning roller 45, and the brush strips of the cleaning roller 45 and the brush roller 41 are cross-distributed. When the brush roller 41 rotates to clean the surface of the conveyor belt 1, the cleaning roller 45 can be driven to rotate in the opposite direction through the meshing of the first gear 42 and the second gear 43, so that the dirt accumulated between the brush strips of the brush roller 41 can be scraped and cleaned, thereby reducing the situation where the brush roller 41 may cause secondary pollution to the surface of the conveyor belt 1, thereby improving the cleaning effect of the brush roller 41 on the surface of the conveyor belt 1.

[0028] The dust suction mechanism 9 includes a partition shell 91, which is fixedly connected to the inner wall of the isolation frame 11. Air-permeable grilles are provided on both sides of the partition shell 91. A fan 92 is installed on one side of the inner cavity of the partition shell 91. The number of fans 92 is several. A dust filter screen 93 is installed on the other side of the inner cavity of the partition shell 91 through the frame. When the fan 92 is started, the air in the isolation frame 11 can be quickly drawn to flow to the outside of the partition shell 91, and the fine feed powder in the air can be moved to the surface of the dust filter screen 93 for interception and filtration, which can reduce the situation where the feed powder on the surface of the conveyor belt 1 is cleaned by the cleaning mechanism 4 and is scattered everywhere. An open slot is provided on one side of the isolation frame 11, and the dust filter screen 93 can be drawn out through the open slot of the isolation frame 11 for replacement or cleaning, thereby ensuring its filtering performance for fine feed powder.

[0029] It is worth noting that the air leakage detection device body 14 proposed in the technical solution is a prior art, which can detect air leakage on the feed packaging bag by squeezing. The working principle and connection method when in use will not be described in detail here.

[0030] Working principle: First, place the bagged feed to be tested on the surface of the conveyor belt 1 for transportation, and then rotate the handle of the worm 862 to engage the worm wheel 863 to rotate, so that the worm wheel 863 can drive the bidirectional screw 81 to rotate, and the sliding blocks 82 on both sides of the surface can drive the sliding column 85 to move. Through the sliding connection between the sliding column 85 and the through groove 84, the baffles 6 on both sides can be synchronously tilted and rotated with the support frame 5 as the center, thereby changing the spacing between the baffles 6 on both sides, and can be performed for feed packaging bags of different sizes, so that they can all be centered and transmitted to the main body 14 of the air leakage detection device for detection, thereby improving the efficiency and accuracy of air leakage detection, and at the same time transmitting When the belt 1 is running, the brush roller 41 will rotate through the transmission of the synchronous pulley component 44, and the feed powder adhered to the surface of the conveyor belt 1 can be automatically cleaned, so as to ensure the efficiency of the conveyor belt 1 in conveying the feed packaging. At this time, through the engagement of the first gear 42 and the second gear 43, the cleaning roller 45 can be rotated in the opposite direction to clean the brush roller 41, so as to reduce the secondary pollution of the surface of the conveyor belt 1 caused by the brush roller 41. Then, the fan 92 is started to make the air inside the isolation frame 11 flow quickly, so as to move the feed powder cleaned by the brush roller 41 to the dust filter screen 93 for interception, filtration and collection, so as to reduce the impact of the feed powder on the surrounding environment.
