Description

Technical Field

[0001] The present invention relates to the field of sealing detection of desiccant packaging bags, and specifically to an automatic packaging bag sealing detection device. Background Art

[0002] Silica gel desiccant generally refers to silica xerogel, which is a transparent or milky white granular solid. It has an open porous structure, strong adsorption capacity, and can adsorb a variety of substances. Its application range is very wide. It is not only used as a special material in the fields of aviation, advanced technology, and military technology, but also used in various sectors of the national economy, and has been extended to: construction, electronics and electrical, textiles, automobiles, machinery, leather and papermaking, chemical industry and light industry, metals and paints, medicine and medical treatment, etc. Existing silica gel particle desiccant packaging bags are generally made of cotton cloth or medium-spun gauze. After putting silica gel particles into the packaging bag, it is then sealed.

[0003] However, small packages of desiccant are generally mass-produced, and there may be a problem of off-cutting during cutting. When off-cutting occurs, the sealing part of the desiccant packaging bag will be cut off or torn, resulting in desiccant leakage. Since silica gel desiccant itself is transparent and the particle diameter is small, it is not easy to be found when leakage occurs. During subsequent packaging, it is easy to be mixed with food, causing accidents. Existing detection generally uses a vision sensor to observe the appearance while the packaging bag is moving for batch detection. Although this detection method has high efficiency, if the outer packaging bag is broken not due to cutting accidents (such as bonding failure, etc.), it is very difficult for the vision device to distinguish from a normal packaging bag. Therefore, the detection result is not very reliable. So, a new detection device is needed that can not only achieve batch detection but also determine the problem of silica gel particle leakage. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides an automatic packaging bag sealing detection device, which solves the problems raised in the above background art.

The positions of the glass plates correspond to each other. The glass plates and the connecting columns form a hollow cylindrical structure. The connecting line between two corresponding glass plates passes through the axis of the hollow cylindrical structure.

[0012] Preferably, the optical detection device includes a laser emission group and a laser reflection and reception group. Both the laser emission group and the laser reflection and reception group are provided with a plurality of them distributed in a circle, and the two are arranged alternately. The laser emission groups are pairwise corresponding, and each corresponds to a glass plate. The laser reflection and reception groups are pairwise corresponding, and one laser reflection and reception group corresponds to a plurality of glass plates. It also includes a connecting frame.

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

[0019] 1. For this automatic packaging bag sealing detection device, by setting a crank mechanism, a detection inner box, and an optical detection device, a group of desiccant packages to be detected need to be placed in the detection inner box. As the crank mechanism operates, the desiccant packaging bags shake in the detection inner box. If the sealing of the desiccant packaging bags fails, the desiccant particles will overflow from the packaging bags and then enter the detection inner box. Since the detection inner box contains a plurality of reflection cones and cylindrical connecting columns, the silica gel particles can be made to jump in the detection inner box while shaking. The reflection cones can make the particles jump up, and the connecting columns can help them reflect and jump on the inner wall of the detection inner box, thereby increasing the jumping height. When there are no silica gel particles jumping, the visible light emitted by the laser head will shine on another group of laser heads. When there are silica gel particles, the silica gel particles will cause the laser to refract, block, or reflect, so that the laser light will be projected onto the reception plate. According to the light frequency of the visible light received on the reception plate, the approximate number of escaped silica gel particles can be determined, and thus the probability of a group of desiccant packaging bags being broken can be judged, thereby realizing the sealing detection of the packaging bags by optics.

[0020] 2. The automatic packaging bag sealing detection device, by setting a suspended support component, when the detection inner box shakes under the control of the crank mechanism, the suspended support component can maintain this effect, enabling the detection inner box to shake more smoothly, and the shaking amplitude of the crank mechanism is relatively small. The elastic damping rod can quickly overcome inertia, greatly increasing the service life of the device, and enabling pipeline operation on the premise of automatic detection of sealing.

[0021] 3. The automatic packaging bag sealing detection device, by setting a quick-release feed nozzle and a discharge bottom, the desiccant packaging bag can be sent to the quick-release feed nozzle along with the pipeline head, and then enter the detection inner box through the upper end of the box body. After the detection is completed, the opening and closing plate rotates by a certain angle to open the discharge hole to achieve automatic discharging. Similarly, in order to improve the detection accuracy, after putting in the desiccant, the quick-release feed nozzle can be removed, and then the sealing cover is used to seal the cover ring. At this time, the shaking amplitude can be increased, facilitating a larger jumping amplitude of the silica gel particles and making the detection structure more accurate.

[0043] The cover ring 402 is of an annular structure. The cover ring 402 corresponds to the quick-release feeding nozzle 2. The inner ring edge at the center of the cover ring 402 is chamfered to facilitate the sliding of the desiccant packaging bag. And a magnet is bonded at the chamfer of the central hole of the cover ring 402 for adsorbing the sealing cover 403. The structure at the bottom end of the sealing cover 403 is also chamfered to cooperate with the cover ring 402. The reflection cone 405 is of a quadrangular pyramid structure, with a smooth surface and is a convex structure. The connecting column 406 is of a hollow tubular structure, and its outer surface is smooth. The glass plate 407 is made of special tempered glass, which can withstand high temperatures and has high light transmittance.

[0044] The discharge bottom 404 includes a bottom ring 4041. A discharge hole 4042 that penetrates up and down is provided on one side of the bottom ring 4041.

[0045] The thickness of the opening and closing plate 4044 fits tightly with the gap between the bottom ring 4041 and the suspension plate 4043. The end of the opening and closing plate 4044 corresponding to the discharge hole 4042 is of a circular structure, and its diameter is just slightly larger than the discharge hole 4042, which can be used to seal the discharge hole 4042.

[0047] The space between the glass plates 407 and the connecting columns 406 is enclosed. The glass plates 407 correspond to each other, and the connecting columns 406 correspond to each other.

[0048] The optical detection device 8 includes a laser emission group 801 and a laser reflection and reception group 802.

[0054] The suspended support assembly 3 includes a reinforcement ring 301, elastic damping rods 302, and a pull ring 303. There are two groups of elastic damping rods 302, reinforcement rings 301, and pull rings 303 respectively. The two groups of elastic damping rods 302 respectively correspond to two reinforcement rings 301 and two pull rings 303. 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 has four. The fixed ends of the elastic damping rods 302 are hinged to the reinforcement rings 301, and the other ends are hinged to the pull ring 303. The two fixed rings 401 are respectively fixed in the two pull rings 303.

[0055] The elastic damping rod 302 is a hydraulic elastic rod, which can play a buffering and shock-absorbing effect, and the hinged end of the elastic damping rod 302 is a ball head.

[0056] The crank mechanism 5 includes a driving machine 501, a rotating wheel 502 and a rocker arm 503. The driving machine 501 is fixed on the inner bottom wall of the box body 1, and the rotating wheel 502 is installed on the output end of the driving machine 501. One end of the rocker arm 503 is rotatably connected to the eccentric point of the rotating wheel 502, and the other end is hinged to the bottom surface of the bottom ring 4041.

[0057] The quick-release feed nozzle 2 includes a bell mouth 201 and a magnetic attraction plate 202 . The bell mouth 201 is fixed on the magnetic attraction plate 202 . The magnetic attraction plate 202 can be adsorbed on the upper surface of the box body 1 . The bell mouth 201 is connected to the internal cavity of the box body 1 .

[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.
