Description

Technical Field

[0001] The present invention relates to the technical field of sealed detection of preservatives, and more specifically, to a sealed detection system for preservatives. Background Art

[0002] Preservatives are a type of food additive that can inhibit the activities of microorganisms and prevent food from spoiling. To ensure a certain shelf life for food, certain measures must be taken to prevent the infection and reproduction of microorganisms. Practice has proven that using preservatives is one of the most economical, effective, and straightforward ways to achieve the above goals. Alcohol preservatives are a type of food additive made mainly from edible alcohol and added with food additives (such as silica). They are mainly used to prevent food from spoiling due to the reproduction of microorganisms during storage and circulation, or due to poor storage and sales conditions resulting in deterioration of food quality and a decrease in color. They form a gas-phase protective layer with a certain concentration around the product to be preserved and are not affected by the pH of the protected food, effectively inhibiting the growth of bacteria and other microorganisms, thus slowing down the process of food spoilage. They are widely used in pastries, dried aquatic products, dried meat products, dried fruit foods, etc. When using preservatives, they usually need to be packaged in plastic bags. After packaging, a detection system is required to detect the sealing performance of the preservatives to ensure the sealing of the preservative packaging.

[0003] According to the search, the patent with the patent number CN118129987B discloses a mooncake packaging bag sealing performance detection device, including: a detection table, a lower pressing plate, a side pressing plate, a lower pressing test connection mechanism, a side pressing test connection mechanism, and a detection driving mechanism. Through the cooperation of the lower pressing test connection mechanism, the side pressing test connection mechanism, and the detection driving mechanism, the present invention realizes the detection of the heat-sealing performance of the packaging bag for the integrated downward slow pressing, rapid downward pressing, lateral slow pressing, and lateral rapid pressing of the packaging bag, combines various detection results to comprehensively evaluate the heat-sealing performance of the mooncake packaging bag, so as to obtain a more comprehensive test result for the heat-sealing of the packaging bag. Moreover, the detection driving mechanism can change its position, enabling the same test driving force to be used for both lateral pressing and downward pressing, which not only improves the convenience of the detection operation but also reduces the detection cost.

[0004] In view of the related technologies described above, after the current preservative is packaged in a packaging bag, in order to ensure the sealing performance after packaging, the above method is usually used to extrude the preservative. After applying pressure to the preservative, check whether there is any preservative leaking from the packaging bag to determine the sealing performance. Although the above method can achieve the pressing test of the preservative, in the actual use process, the preservative will be extruded by objects of different shapes, and the shape of the pressing plate is fixed during the above test, which is not convenient to switch to more types of pressing objects for pressing, resulting in certain limitations in the test, and further making the test not comprehensive. Therefore, a sealing detection system for preservatives is proposed. Summary of the Invention

[0021] The following will further describe the present invention in detail with reference to the Figures 1-7 accompanying drawings.

[0022] Please refer to Figures 1-7 , a sealing detection system for a preservative, comprising a main body module 100 and a continuous comprehensive detection module 200. The main body module 100 includes a device frame 110. An n-shaped frame 120 is fixedly connected to the rear end face of the device frame 110. A conveying component 130 is arranged on the front end face of the device frame 110. A transverse groove 140 is formed at the top of the device frame 110. The continuous comprehensive detection module 200 includes a central rotating shaft 210 rotatably connected between the inner top and bottom of the device frame 110. A plurality of pressing components 220 are arranged on the outer surface of the central rotating shaft 210 at equal intervals in a ring shape. The bottoms of the plurality of pressing components 220 are all connected with pressing blocks 230. The shapes and bottom areas of the plurality of pressing blocks 230 are all different. A steering component 240 is arranged between the outer surface of the central rotating shaft 210 and the inner wall of the n-shaped frame 120. A lifting component 250 is arranged inside the transverse groove 140. The lifting component 250 is located directly above one of the pressing components 220. An adapter component 260, an adjustment component 270 and a driving component 280 are arranged on one side of the device frame 110. The adapter component 260 is connected to the lifting component 250. The adjustment component 270 is connected between the driving component 280 and the adapter component 260. The driving component 280 is adapted to the steering component 240.

[0023] During the detection process, the preservatives that need to be tested after packaging will be conveyed on the conveying component 130. When the preservative is displaced below one of the pressing components 220, the driving component 280 is turned on. The driving component 280 will first drive the adjustment component 270, and the adjustment component 270 will drive the connection component 260 to perform reciprocating motion. The connection component 260 will drive the lifting component 250 to perform lifting operations. When the lifting component 250 moves up and down, it will press one of the pressing components 220. One of the pressing components 220 will drive one of the pressing blocks 230 to descend to apply a certain pressing force to the preservative. After the pressing is completed, the pressing component 220 will drive one of the pressing blocks 230 to reset. Subsequently, the driving component 280 drives the steering component 240, and the steering component 240 will drive the central rotating shaft 210 to rotate by a certain angle, so that another pressing component 220 is displaced below the lifting component 250. Subsequently, the driving component 280 drives the adjustment component 270 again, and the operation of the adjustment component 270 causes another pressing component 220 to drive another pressing block 230 to perform a descending pressing operation. Repeat the above steps to press all the pressing blocks 230 against the preservative, so as to perform a more comprehensive pressing test on the preservative through the pressing blocks 230 of different shapes. Subsequently, check whether there is any leakage in the preservative that has been comprehensively pressed. By adjusting the adjustment component 270, the pressing force when the pressing block 230 presses down can be changed, so as to perform tests with different pressing forces according to different preservatives and improve the applicability of the detection system.

[0024] The pressing assembly 220 includes a mounting arm 221 fixedly connected to the outer surface of the central rotating shaft 210. A sleeve cylinder 222 is movably connected inside the mounting arm 221.

One end of each of the two push rods 256 is articulated to the bottom of the two moving seats 255.

[0025] When the bidirectional lead screw 253 rotates, it will drive the two moving seats 255 to approach each other. The two moving seats 255 will push the pressing plate 252 through the two push rods 256. The pressing plate 252 will press the sleeve cylinder 222 to descend. When the sleeve cylinder 222 descends, it will pull the first spring 223. At the same time, one of the pressing blocks 230 contacts the outside of the preservative and presses it. At this time, the inner movable rod 224 moves upward inside the sleeve cylinder 222, and at the same time, the second spring 225 contracts to increase the pressure applied to one of the pressing blocks 230, so as to apply a certain force to press the preservative. After the pressing is completed, the incomplete gear 282 drives the first connecting gear 247. The first connecting gear 247 drives the connecting long rod 244 to rotate. When the connecting long rod 244 rotates, it will drive the rotating column 241 to rotate 360 degrees through the meshing of the two bevel gears 245. The rotating column 241 drives the Geneva groove wheel 242 to rotate a certain angle through the Geneva driving wheel 243, so that the other pressing assembly 220 is displaced below the lifting assembly 250. Subsequently, the incomplete gear 282 drives the second sleeve gear 277 again, so that through the operation of the adjustment assembly 270, the other pressing assembly 220 will drive the other pressing block 230 to perform a descending pressing operation. Repeat the above steps to press all the pressing blocks 230 against the preservative.

The outer surface of the incomplete gear 282 is adapted to the outer surface of the first connection gear 247.

[0027] By pressing the second sector gear 264, the second sector gear 264 will drive the hexagonal rod 267 into the hollow shaft 265 while the third spring 268 contracts, and the second sector gear 264 disengages from the first sleeve gear 263. At this time, by pushing the actuating block 276 to drive the adjustment screw 274 to rotate, the adjustment screw 274 will drive the drive shaft 275 to displace. After the adjustment is completed, release the second sector gear 264, and the hollow shaft 265 will drive the second sector gear 264 to reset and reconnect with the first sleeve gear 263, thereby changing the amplitude of the swing of the second sector gear 264 driven by the rotation of the subsequent drive shaft 275, and further changing the pressing amplitude of the pressing plate 252, so as to change the force when the pressing block 230 presses down, so as to perform tests with different pressing forces according to different preservatives.

[0029] The preservatives that need to be tested after packaging will be placed on the conveyor belt 133. Turn on the second motor 134, and the second motor 134 will drive one of the conveying rollers 132. The conveying roller 132 will drive the conveyor belt 133 to roll, so as to convey one of the preservatives above the support frame plate 135, and the preservative is located below one of the pressing assemblies 220. Turn on the second motor 134, and the second motor 134 will drive the conveying roller 132, and the conveying roller 132 will drive the conveyor belt 133 to convey the next preservative for detection, thereby improving the efficiency without manual replacement by the staff. During detection, the support frame plate 135 supports the preservative.

[0030] The implementation principle of the embodiment of the present invention is as follows: During the detection process, the preservatives to be tested after packaging will be placed on the conveyor belt 133. The second motor 134 is turned on, and the second motor 134 will drive one of the conveyor rollers 132. The conveyor roller 132 will drive the conveyor belt 133 to roll, so as to convey one of the preservatives above the support plate 135, and the preservative is located below one of the pressing components 220. The first motor 281 is turned on, and the first motor 281 will drive the incomplete gear 282. The incomplete gear 282 will drive the second set gear 277 to drive the second rotating shaft 271 to rotate 360 degrees. The second rotating shaft 271 drives the driving disc 272 and the driving shaft 275 to rotate. The driving shaft 275 will move inside the hollow arm 266 and push the hollow arm 266 to swing up and down. The hollow arm 266 drives the hollow shaft 265 and the second sector gear 264 to swing. When the second sector gear 264 swings clockwise, it will drive the first set gear 263 to drive the first rotating shaft 261 to rotate, so that the first sector gear 262 drives the second connecting gear 254. The second connecting gear 254 drives the bidirectional lead screw 253 to rotate. When the bidirectional lead screw 253 rotates, it will drive the two moving seats 255 to approach each other. The two moving seats 255 will push the pressing plate 252 through the two push rods 256. The pressing plate 252 will press the sleeve cylinder 222 to descend. When the sleeve cylinder 222 descends, it will pull the first spring 223. At the same time, one of the pressing blocks 230 contacts the outside of the preservative and presses it. At this time, the inner movable rod 224 moves upward inside the sleeve cylinder 222, and at the same time, the second spring 225 contracts to increase the pressure applied to one of the pressing blocks 230, so as to apply a certain force to press the preservative. After the pressing is completed, the second sector gear 264 moves in the reverse direction, so as to drive the first sector gear 262 to reset. The first sector gear 262 drives the second connecting gear 254 in the reverse direction, so that the pressing plate 252 resets, and at the same time, the pressing block 230 resets. Subsequently, the incomplete gear 282 drives the first connecting gear 247, and the first connecting gear 247 drives the connecting long rod 244 to rotate. When the connecting long rod 244 rotates, it will drive the rotating column 241 to rotate 360 degrees through the meshing of the two bevel gears 245. The rotating column 241 drives the Geneva grooved wheel 242 to rotate a certain angle through the Geneva driving wheel 243, so that another pressing component 220 is displaced below the lifting component 250. Subsequently, the incomplete gear 282 drives the second set gear 277 again, so that through the operation of the adjustment component 270, another pressing component 220 will drive another pressing block 230 to perform a descending pressing operation. Repeat the above steps to press all the pressing blocks 230 on the preservative, so as to perform a more comprehensive pressing test on the preservative through the pressing blocks 230 of different shapes. Subsequently, check whether the preservative after comprehensive pressing leaks to judge the sealing performance. By pressing the second sector gear 264,The second sector gear 264 will drive the hexagonal rod 267 to enter the interior of the hollow shaft 265. At the same time, the third spring 268 will contract, and the second sector gear 264 will be separated from the first set gear 263.
