[0025] Embodiment 1: Please refer to Figure 1-6, the present utility model provides a technical solution: a secondary precise weighing funnel for a blood collection needle, including a weighing funnel 100 of a packaging machine. An optoelectronic sensor is provided on the weighing funnel 100 of the packaging machine.

An adjusting plate 303 is threadedly installed on the adjusting screw rod 301. The adjusting plate 303 is slidably installed on one side of the weighing funnel 100 of the packaging machine. The adjusting plate 303 is fixedly installed on the side of the two guiding plates 201. By turning on the corresponding adjusting motor 302, its output end can drive the adjusting screw rod 301 to rotate. The rotating adjusting screw rod 301 will drive the two guiding plates 201 to slide, so that the sliding guiding plates 201 drive the guiding sliders 206 on both sides to slide in the two guiding chutes 205 respectively, avoiding the deviation of the guiding plates 201. The continuously sliding guiding plates 201 will drive the partition plate 202 to slide in the adjusting hole 200, so as to be able to adjust the height of the partition plate 202 in the material dropping hole 101, achieving the effect of adjusting the distance between the upper and lower partition plates 202, so as to adjust according to the size specifications and quantity of the blood collection needles to be packaged.

[0028] In order to avoid the deviation of the guiding plates 201, guiding chutes 205 are opened on both inner walls of the adjusting hole 200. Guiding sliders 206 are slidably installed in both guiding chutes 205. The two guiding sliders 206 are fixedly installed on both sides of the two guiding plates 201.

[0029] The inner wall of the adjusting plate 303 is provided with an adjusting screw hole 304, and the adjusting screw rod 301 is threadedly installed in the adjusting screw hole 304. The rotating adjusting screw rod 301 will drive the adjusting plate 303 to slide through the cooperation with the adjusting screw hole 304.

[0030] Embodiment 2: As Figure 2-6 , in order to prevent the blood collection needle material from falling into the adjusting hole 200, a shielding structure is arranged on the connecting seat 400. The shielding structure includes two rotating shafts 401. The two ends of the two rotating shafts 401 are respectively rotatably installed on the corresponding four connecting seats 400. Two winding rollers 402 are fixedly sleeved on the two rotating shafts 401. One ends of two shielding cloths 403 are respectively fixedly installed on the two winding rollers 402. The other ends of the two shielding cloths 403 are respectively fixedly installed on the sides of the two guide plates 201 away from each other. The two shielding cloths 403 are respectively wound around the two winding rollers 402. Two fixing strips 404 are fixedly installed on the inner wall of the adjusting hole 200. The two shielding cloths 403 are respectively in contact with the two fixing strips 404. The two shielding cloths 403 are both located on one side of the adjusting hole 200. One end of a leaf spring 405 is fixedly installed on the inner wall of the connecting seat 400. The other end of the leaf spring 405 is fixedly installed on the rotating shaft 401. A rotating hole 406 is formed in the inner wall of the connecting seat 400. One end of the rotating shaft 401 is rotatably installed in the rotating hole 406. A through hole 407 is formed between the fixing strip 404 and the adjusting hole 200. The shielding cloth 403 passes through the through hole 407. During the movement of the two guide plates 201, a corresponding shielding cloth 403 will be pulled. When the shielding cloth 403 is pulled, it will drive one of the winding rollers 402 to rotate and release the wound shielding cloth 403. When the winding roller 402 rotates, it will drive the rotating shaft 401 to rotate in the corresponding rotating hole 406 to avoid deviation. The continuously rotating rotating shaft 401 will compress the leaf spring 405. On the other hand, the moving guide plate 201 will slowly relax the other shielding cloth 403, and the leaf spring 405 at its corresponding position is in a compressed state. When the other shielding cloth 403 is relaxed, the compressed leaf spring 405 will be released and drive the other winding roller 402 to rotate through the other rotating shaft 401, so that the winding roller 402 winds the shielding cloth 403, so that the shielding cloths 403 on the two guide plates 201 can shield the adjusting hole 200 according to the moving degree of the guide plates 201, preventing the material from falling out through the adjusting hole 200. The remaining features are the same as those in Embodiment 1.

[0031] The working principle is as follows: When measuring the blood collection needle, the blood collection needle will fall into the material dropping hole 101 on the weighing funnel 100 of the packaging machine under the conveyance of the conveyor belt. Combining with the existing technology, it can be known that when the material enters the weighing funnel 100 of the packaging machine, the photoelectric sensor can be used to detect the quantity of the material. During the process, the material will fall onto the partition plate 202 in the material dropping hole 101. When the set quantity is reached, the driving cylinder 204 will be activated. The output end of the driving cylinder 204 will push the connecting plate 203 to move. The moving connecting plate 203 will drive the partition plate 202 to move out of the material dropping hole 101, so that the blood collection needle material accumulated on the partition plate 202 will fall for packaging. By arranging two partition plates 202 in one material dropping hole 101, the two partition plates 202 can cross-move. When in use, both partition plates 202 are located in the material dropping hole 101. The material will first fall onto the partition plate 202 close to the feeding port. When the quantity reaches the set value, the upper partition plate 202 will be controlled by the driving cylinder 204 to move out of the material dropping hole 101, so that the material will fall onto the lower partition plate 202. Then the upper partition plate 202 will re-enter the material dropping hole 101. At this time, the lower partition plate 202 will extend out of the material dropping hole 101, causing the material to fall, so that the material falls in segments, avoiding damage caused by too long falling distance of the material. By activating the corresponding adjusting motor 302, its output end can drive the adjusting screw rod 301 to rotate. The rotating adjusting screw rod 301 will rotate on the two fixed seats 300, thus preventing the adjusting screw rod 301 from shifting. The continuously rotating adjusting screw rod 301 will drive the adjusting plate 303 to slide through the cooperation with the adjusting screw hole 304. During the sliding process of the adjusting plate 303, it will drive the two guide plates 201 to slide. The continuously sliding guide plates 201 will drive the partition plate 202 to slide in the adjusting hole 200, so as to adjust the height of the partition plate 202 in the material dropping hole 101, achieving the effect of adjusting the distance between the upper and lower partition plates 202. It can adjust the partition plate 202 upward during material dropping, lower it after receiving the material, and then retract the partition plate 202, so that the falling height of the material is further reduced, so as to adjust according to the size specifications and quantity of the blood collection needles to be packaged. And during the movement of the two guide plates 201, a corresponding shielding cloth 403 will be pulled. When the shielding cloth 403 is pulled, it will drive one of the winding rollers 402 to rotate and release the wound shielding cloth 403. When the winding roller 402 rotates, it will drive the rotating shaft 401 to rotate in the corresponding rotating hole 406, preventing deviation. The continuously rotating rotating shaft 401 will compress the spring piece 405. On the other hand, the moving guide plate 201 will slowly loosen the other shielding cloth 403, and the spring piece 405 at its corresponding position is in a compressed state. When the other shielding cloth 403 is loosened, the compressed spring piece 405 will be released and drive the other winding roller 402 to rotate through the other rotating shaft 401, so that the winding roller 402 winds up the shielding cloth 403.Enable the shielding cloth 403 on the two guide plates 201 to shield the adjustment holes 200 according to the degree of movement of the guide plates 201, preventing materials from falling out through the adjustment holes 200.

[0032] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
