Description

Technical Field

[0001] The invention relates to the field of seal detection of desiccant packaging bags, and in particular to an automatic packaging bag seal detection device. Background Art

[0002] Silica gel desiccant generally refers to silicate xerogel, which is a transparent or milky white granular solid. It has an open porous structure, strong adsorption, and can adsorb a variety of substances. Its application range is very wide. It is not only used as a special material in aviation, cutting-edge technology, and military technology departments, but also used in various sectors of the national economy, which has expanded to: construction, electronics and electrical, textiles, automobiles, machinery, leather and papermaking, chemical and light industry, metals and paints, medicine and medical treatment, etc. The existing silica gel granule desiccant packaging bags are generally made of cotton cloth or medium-spun yarn cloth. After the silica gel granules are placed in the packaging bag, they are sealed.

[0003] However, small packages of desiccant are generally mass-produced, and there may be problems with the knife being skewed during cutting. When the knife is skewed, the seal of the desiccant bag may be cut or torn, which may cause desiccant leakage. Since the silica gel desiccant itself is transparent and the diameter of the particles is small, it is not easy to be discovered when a leak occurs. During later packaging, it is easy to mix with food and cause accidents. Existing detection generally uses visual sensors to observe the appearance of the packaging bag while it is moving, so as to facilitate batch detection. Although this detection method is more efficient, if the outer packaging bag is not broken due to a cutting accident (such as bonding failure, etc.), it is difficult for visual equipment to distinguish it from a normal packaging bag. Therefore, the detection structure is not very reliable. Therefore, a new detection equipment is needed that can not only realize batch detection but also determine the problem of silica gel particle leakage. Summary of the invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The automatic packaging bag sealing detection device is provided with a crank mechanism, a detection inner box and an optical detection device. A group of desiccant packages to be detected needs to be placed in the detection inner box. With the operation of the crank mechanism, the desiccant packaging bag shakes in the detection inner box. If the seal of the desiccant packaging bag itself fails, the desiccant particles will overflow from the packaging bag and then enter the detection inner box. Since the detection inner box contains multiple reflection cones and cylindrical connecting columns, the silica gel particles can be caused to jump in the detection inner box while shaking. The reflection cone can make the particles rise, and the connecting column can help them reflect and jump in the inner wall of the detection inner box, thereby increasing their jumping height. When there are no silica gel particles jumping, the visible light emitted by the laser head will irradiate another group of laser heads. When there are silica gel particles, the silica gel particles will refract, block or reflect the laser, so that the laser light will be projected to the receiving board. According to the light frequency of the visible light received on the receiving board, the approximate number of escaped silica gel particles can be determined, thereby determining the probability of a group of desiccant packaging bags being broken, thereby realizing the sealing detection of the packaging bag using optics.

[0020] 2. The automatic packaging bag sealing detection device is provided with a suspended support component. When the crank mechanism controls the shaking of the inner box to be detected, the suspended support component can maintain this function, which can make the shaking of the inner box to be detected smoother, and the shaking amplitude of the crank mechanism is small. The elastic damping rod can quickly overcome inertia, so that the service life of the device is greatly increased, and assembly line operation can be realized under the premise of automatic detection and sealing.

[0021] 3. The automatic packaging bag sealing detection device is provided with a quick-release feed nozzle and a discharge bottom. The desiccant packaging bag can be sent to the quick-release feed nozzle along the assembly line head, and then enter the detection inner box through the upper end of the box. After the detection is completed, the opening and closing plate rotates a certain angle to open the discharge hole to realize automatic unloading. Similarly, in order to increase the detection accuracy, after putting in the desiccant, the quick-release feed nozzle can be removed, and then the cover ring can be closed with a sealing cover. At this time, the shaking amplitude can be increased to facilitate a larger jumping amplitude of the silica gel particles and a more accurate detection structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] The suspended support assembly 3 includes a reinforcement ring 301, an elastic damping rod 302 and a pull ring 303. The elastic damping rod 302, the reinforcement ring 301 and the pull ring 303 are respectively provided with two groups. The two groups of elastic damping rods 302 correspond to two reinforcement rings 301 and two pull rings 303 respectively. The two reinforcement rings 301 are respectively fixed to the upper and lower ends of the inner wall of the box body 1. Each group of elastic damping rods 302 is provided with four.

[0058] The bell mouth 201 corresponds concentrically to the cover ring 402 .

[0059] When in use, the desiccant packaging bag can be sent to the quick-release feed nozzle 2 along with the assembly line head, and then enter the detection inner box 4 through the upper end of the box body 1. In order to increase the detection accuracy, the quick-release feed nozzle 2 can be removed, and then the cover ring 402 can be closed with the sealing cover 403. As the crank mechanism 5 operates, when the driving machine 501 drives the detection inner box 4 to shake, the suspended support assembly 3 can maintain this effect, which can make the detection inner box 4 shake more smoothly, and the shaking amplitude of the crank mechanism 5 is small, and the elastic damping rod 302 can quickly overcome inertia, thereby adapting to batch desiccant packaging bag detection.

[0060] As the crank mechanism 5 operates, the desiccant bag shakes in the detection inner box 4. If the seal of the desiccant bag fails, the desiccant particles will overflow from the bag and then enter the detection inner box 4. Since the detection inner box 4 includes multiple reflection cones 405 and cylindrical connecting columns 406, the silica gel particles can be caused to jump in the detection inner box 4 while shaking. The reflection cones 405 can make the particles rise, and the connecting columns 406 can help them reflect and jump in the inner wall of the detection inner box 4, thereby increasing their jumping height. When the silica gel particles jump, the visible light emitted by the laser head 8013 will irradiate another group of laser heads 8013, which proves that there is no seal leakage problem in any desiccant bag of this batch. When there are silica gel particles, the silica gel particles will refract, block or reflect the laser, so that the laser light will be projected onto the receiving plate 8022. The approximate number of escaped silica gel particles can be determined based on the light frequency of the visible light received on the receiving plate 8022, thereby determining the probability of a group of desiccant bags being broken.

[0061] After the detection is completed, the opening and closing plate 4044 rotates a certain angle to open the discharge hole 4042 to realize automatic unloading. If there are many silica gel particles, the unloading will fall into the inner bottom wall of the box body 1, which is convenient for quickly separating the desiccant particles from the detection inner box 4. At this time, the next batch of detection can be carried out, and the separated silica gel particles will be discharged from the trumpet-shaped discharge port 6 and the through hole 7.
