The contact surfaces between the first roller 1310 and the second roller 1320 are respectively located on the long sides of the sampling stick to be removed from the bag, so that the packaging bag can be prevented from being released and deviated during the moving process. And avoid squeezing the sampling rod, causing damage to the sampling rod.

The position where the third cylinder 1410 and the fourth cylinder 1420 want to contact is also located on both sides of the third cylinder 1410 and the fourth cylinder 1420 in the axial direction, so as to cooperate with the first roller assembly, so that the sampling stick to be removed from the bag is directed toward the outlet. The direction of material port 1120 is transported.

As shown in FIG. 3 and FIG. 4 , there is a first channel 1330 between the first roller 1310 and the second roller 1320 , and a second passage 1330 between the third roller 1410 and the fourth roller 1420 .

In this way, damage to the sampling rod is avoided.

Optionally, the outer peripheral surface of the third roller 1410 is covered with a damping layer 1411 , and the pressure roller is pressed against the damping layer 1411 . The damping layer 1411 can increase the frictional force, and the material of the damping layer 1411 is the same as that of the damping ring 1311 , which will not be repeated here.

The distance between the end of the baffle plate 1700 close to the plate body 1230 and the bottom plate 1200 matches the thickness of the sampling stick to be removed from the bag. In this way, multiple sampling rods can be prevented from entering the first roller assembly at the same time.

According to one embodiment of the present invention, a feeding device is provided. According to one embodiment of the present invention, a feeding device is provided. The feeding device includes a base 2210 having a receiving chamber 2110 . A bracket 2220 is also included, and the bracket 2220 is fixed on the base 2210 . And the shell 2300, the shell 2300 is detachably connected with the base 2210, the shell 2300 encloses the feeding chamber, the side of the shell 2300 facing the base 2210 is provided with a feeding port, the feeding chamber The feed port communicates with the housing cavity 2110, and the feed cavity is used to accommodate a plurality of stacked sampling sticks 3000 to be removed from the bag. There are through holes 2310 . It also includes a conveying assembly 2500, at least part of which is located in the accommodating chamber 2110, the conveying assembly 2500 is opposite to the feeding port, and the conveying assembly 2500 is used for removing the sampling stick 3000 to be removed from the bag. Transport to the bag removal mechanism for bag removal. And a pressing plate structure, the pressing plate structure is slidably connected with the bracket 2220, the pressing plate structure can enter the feeding chamber through the through hole 2310, and move along the bracket 2220, the pressing plate structure is used for A sampling stick 3000 stacked in the feeding cavity to be removed from the bag is pressed and held on the conveying assembly 2500 by the feeding port.

As shown in FIG. 5 and FIG. 8 , the base 2210 includes a bottom plate 2120 and a plurality of side plates 2130 extending from the bottom plate 2120 in a direction perpendicular to the bottom plate 2120 . For convenience of description, the side panel 2130 of the base 2210 in FIG. 4 is hidden to show the state of the accommodating cavity 2110 . The bracket 2220 extends along the first direction, and is fixed on the bottom plate 2120 of the base 2210 , and can also be fixed on the side plate 2130 of the side plate 2130 . The housing 2300 is located on the upper portion of the base 2210 . The shell 2300 is located inside the bracket 2220 and spaced apart from the bracket 2220 along the second direction. A side of the housing 2300 facing the base 2210 is provided with a feed port. The size of the feeding port matches the size of the sampling stick 3000 to be removed from the bag, so that the sampling rod 3000 to be removed from the bag can be pressed out through the feeding port. The sampling sticks 3000 to be removed from the bag are stacked in the accommodating chamber 2110, and are opposite to the feeding port.

As shown in FIG. 5 , the through hole 2310 is located at the top of the housing 2300 . The transport assembly 2500 can be a roller or a belt. The conveying assembly 2500 can send the sampling stick 3000 to be removed from the bag out of the feeding device along the second direction, and send it to a set position. For example, the feeding device has a first discharge port, and the first discharge port is connected with the bag removing device, and the sampling stick 3000 to be removed from the bag is sent out of the first discharge port by the conveying assembly 2500 . The pressing plate structure can apply pressure from top to bottom along the first direction. The pressing plate structure protrudes from the bracket 2220 toward the position where the housing 2300 is located. When the pressing plate structure is located at the top of the guide rod 2210 , the pressing plate structure is suspended on the casing 2300 and is opposite to the through hole 2310 .

For example, it may be that the through hole 2310 extends along the surface of the housing 2300 and matches the axial length direction of the sampling rod 3000 to be removed from the bag. It is also possible that the through hole 2310 extends along the surface of the housing 2300 to match the front end of the sampling stick 3000 to be removed from the bag. The size of the portion of the pressing plate structure that can extend into the through hole 2310 is smaller than or equal to the size of the through hole 2310 , so as to hold the corresponding position of the sampling stick 3000 to be removed from the bag within the scope of the through hole 2310 . The bracket 2220 extends along the axial direction of the feed chamber.

The sampling stick 3000 to be removed from the bag is transported to the set position by the conveying assembly 2500 along with the rotation of the conveying assembly 2500 for bag removal.

In this way, the feeding device in this embodiment can automatically transport the sampling stick 3000 to be removed from the bag to the set position, so that other devices can remove the bag from the sampling rod. In this way, it is avoided that the sampling robot first grabs a sampling stick 3000 to be removed from the bag when sampling, and puts the sampling stick 3000 to be removed into the bag removal device, and then the sample rod after the bag removal is removed from the bag removal device. The waste of timing caused by taking out the middle improves the sampling efficiency.

In addition, during the process of manual sampling, the feeding device can automatically transport the sampling stick 3000 to be removed from the bag to the set position, and the manual sampler does not need to put the sampling stick 3000 to be removed into the bag removing device. Thus, the sampling efficiency of manual samplers is improved.
