[0025] As Figure 1 、 2As shown, the compression solid component 130 includes a slider 131 connected with the guide rod 120, two guide wheels 132 are respectively arranged at two ends of the slider 131, and a first pressing plate 133 is further connected with one side of the slider 131. The slider 131 drives the first pressing plate 133 to slide along the side of the conveying belt 100, and the end of the first pressing plate 133 is provided with a pressing port 134. When the compression solid component 130 is pressed down, the pressing port 134 can press the inlet end of the quantitative valve on the edge of the conveying groove 110, prevent the quantitative valve from moving, and make the cannulation work smoothly. The base 200 is connected with a guide rail 270 below, and the tail end of the base 200 is connected with a reciprocating driving mechanism 260 for driving the base 200 to reciprocate along the guide rail 270. The reciprocating driving mechanism 260 includes a connecting rod 261, one end of the connecting rod 261 is connected with the tail end of the base 200, and the other end of the connecting rod 261 is connected with a crank 262, one end of the crank 262 is used for connecting a rotary driving device.

When the base 200 advances, the compression rod 220 can contact with the guide wheel 132, and drive the compression solid component 130 to press down. In actual application, the rotary driving device can be selected from various driving motors commonly used in the market.

[0026] As shown in the figure, Figure 3 The base 200 is provided with a first tube groove 211, the top of the base 200 is provided with a limiting groove 210, the first tube groove 211 is arranged at the groove bottom of the limiting groove 210, and a corresponding tube pressing mechanism 230 is arranged on the first tube groove 211. The tube pressing mechanism 230 includes a support plate 231 fixed on the top of the base 200, a first cylinder 232 is arranged above the support plate 231, a second pressing plate 233 is connected with the first cylinder 232, and a second tube groove 234 corresponding to the first tube groove 211 is arranged at the bottom of the second pressing plate 233. When the first cylinder 232 drives the second pressing plate 233 to press down, the second tube groove 234 can cooperate with the first tube groove 211 to press the straw tightly, prevent the straw from moving, and the limiting groove 210 is used to improve the working stability of the tube pressing mechanism 230.

[0027] As shown in the figure, Figure 4As shown, the base 200 front end is provided with pipe cutting mechanism 240, the pipe cutting mechanism 240 includes guide seat 241, guide seat 241 below fixedly connected with the second cylinder 244, the second cylinder 244 is connected with the cutter seat 245, the cutter seat 245 is provided with cutter 246, the cutter 246 is obliquely arranged, the guide seat 241 is provided with guide hole 242 and the knife hole 243 through the guide hole 242, the cutter 246 is located in the knife hole 243 and moves. The pipe cutting mechanism 240 is used to cut the suction tube, when the cannula is completed, the reciprocating mechanism drives the base 200 to move backward, the base 200 drives the pipe cutting mechanism 240 to move, when the pipe cutting mechanism 240 moves to the appropriate position, the second cylinder 244 drives the cutter 246 to move along the knife hole 243, the cutter 246 can cut the suction tube to the appropriate length, and the cut is inclined.

[0028] As Figure 5 shown, the pipe cutting mechanism 240 and the base 200 are provided with buffer mechanism 250, the buffer mechanism 250 includes the support rod 251 connected with the back of the guide seat 241, the support rod 251 penetrates the base 200, and the end is provided with the pressing part 252, the base 200 is provided with the buffer seat 253, the buffer seat 253 is provided with the accommodating groove 254, the pressing part 252 is located in the accommodating groove 254 and slides, and the second spring 255 is further arranged between the pressing part 252 and the groove bottom of the accommodating groove 254. During the cannula work, the suction tube needs to be pushed forward, and a certain force is needed to insert the suction tube on the quantitative valve. Because the suction tube is relatively long, if the end of the suction tube is not fixed, the suction tube will bend after contacting the quantitative valve, which will cause the cannula to be unable to be inserted. Therefore, the guide hole 242 is used to fix the end of the suction tube during the cannula work, to ensure the cannula work. After the suction tube is inserted into the quantitative valve, the base 200 needs to drive the suction tube to advance a distance, so that the suction tube is completely connected with the quantitative valve. The guide seat 241 is blocked by the conveying belt 100, and needs to avoid damaging the quantitative valve, so it cannot continue to advance. At this time, the buffer mechanism 250 can make the base 200 still have space to advance when the guide seat 241 cannot advance.

[0029] Working process: during the process of inserting the pipe, the suction pipe passes through the first pipe groove 211 and the guide hole 242, when the reciprocating motion driving mechanism 260 drives the base 200 to advance, the pipe pressing mechanism 230 cooperates with the first pipe groove 211 to press the suction pipe tightly and drive the suction pipe to advance, at the same time, the pressing surface 221 of the pressing rod 220 slides against the surface of the guide wheel 132, so that the pressing and fixing assembly 130 presses down to fix the quantitative valve on the material conveying groove 110, the base 200 drives the suction pipe to advance continuously, and finally the suction pipe is inserted on the inlet end of the quantitative valve. After the pipe inserting work is completed, the pipe pressing mechanism 230 stops pressing the pipe, the reciprocating motion driving mechanism 260 drives the base 200 to retreat, the base 200 drives the pipe cutting mechanism 240 to retreat, and after the pipe cutting mechanism 240 retreats to the appropriate position, the second cylinder 244 drives the cutter 246 to cut the suction pipe.

[0030] The above embodiment is a preferred implementation manner of the utility model, and is not a limitation on the utility model, and any obvious replacement without departing from the utility model concept is within the protection scope of the utility model.
