Description

Technical Field

[0001] This utility model relates to the field of sampling technology, and in particular to a sampling device for the net content of quantitatively packaged goods. Background Technology

[0002] Prepackaged goods refer to pre-packaged goods intended for sale, closely related to consumer interests, and with uniform quality, volume, and length markings within a certain quantity limit. During the production process of prepackaged goods, sampling inspection devices are required to test the net content of the goods.

[0003] The equidistant sampling inspection method is suitable for sampling qualified products at the end of the production line or at the product packaging site. The sampling method involves taking one sample at intervals of a certain number of units of goods or at certain time intervals until the required sample size is reached. The sampling interval is equal to the time required to produce a batch of products divided by the sample size. Existing equidistant sampling inspection devices use a clamping sampling method to sample goods flowing on the production line. However, the position of the sampling device is often fixed, meaning the clamping sampling device is always fixed at a designated position on the production line. During sampling, because the goods are transported on the production line, the fixed-position clamping sampling device is prone to collision with the next flowing goods when the sampled goods are large, causing damage to the goods and disrupting the transport position of the next goods on the production line. In view of this, this application proposes a sampling inspection device for the net content of quantitatively packaged goods. Utility Model Content

[0048] In this invention, by setting up a driving component 300, the device can easily sample and inspect goods on the conveyor line during the movement of the sampling component 200, thus avoiding collisions between the sample goods and other goods and ensuring the safety of goods transportation.

[0049] Working Principle: When sampling and inspecting pre-packaged goods, this device is placed next to the conveyor line, with the two gripping plates 204 positioned directly above the conveyor line. Then, the fourth motor 302 is activated. The rotation of the fourth motor 302 drives the horizontal threaded column 304 to rotate, which in turn moves the slider 303. The slider 303 then moves the hollow seat 201, causing the sampling component 200 to slide above the strip plate 301. This, in turn, causes the strip frame 203 and gripping plates 204 to move along with the conveyed goods above the conveyor line. Next, the second motor 206 is activated. The rotation of the second motor 206 drives the vertical threaded column 209 to rotate, which in turn moves the lifting plate 2010 downwards. As the lifting plate 2010 moves downwards, it moves the strip frame 203 and the two gripping plates 204 downwards to the sides of the goods. Then, the second motor 206 is turned off, and the first motor 205 is activated. The rotation of the first motor 205 drives the bidirectional lead screw 208 to rotate. The rotation of the bidirectional lead screw 208 drives the two clamping plates 204 to move automatically towards the center, thereby enabling the two clamping plates 204 to effectively clamp and sample the goods. Then, the second motor 206 is started again to reverse, driving the strip frame 203 to move upward, lifting the clamped goods sample to the highest point. Then, the second motor 206 is turned off and the third motor 207 is started. The rotation of the third motor 207 drives the active gear plate 2013 to rotate. The rotation of the active gear plate 2013 drives the driven gear plate 2014 and the rotating rod 2011 to rotate. The rotation of the rotating rod 2011 drives the column 202 to rotate 180 degrees, thereby causing the clamped goods sample to leave the area of ​​the conveyor line. Finally, the second motor 206 and the first motor 205 are started respectively to put down the goods sample, realizing the purpose of automatic sampling and inspection. Moreover, it can perform sampling and inspection of the goods sample during the movement of the sampling component 200.
