[0002] The syringe is a common medical device. The syringe is composed of a jacket, a core rod, a rubber stopper, a handle and a cone head. After the syringe is produced and processed, it needs to be packaged. During packaging, the syringe needs to be automatically loaded by an automatic loading device, which can effectively improve the production speed of the syringe. The loading device includes a feeder, an isolation mechanism and a loading mechanism. Through the cooperation of different mechanisms, the syringe can be quickly and automatically loaded during packaging;

[0003] After searching, the utility model patent with Chinese patent publication number CN220221318U discloses: an automatic feeding mechanism for syringe production, including a feeding bin, the top of which is fixedly connected to a feed bin, the left and right sides of the inside of the feed bin are respectively provided with a left groove and a right groove, the bottom of the feeding bin is fixedly connected to a discharge port, an opening and closing mechanism is provided inside the feeding bin, the opening and closing mechanism includes a connecting plate, a left stopper and a right stopper, and the connecting plate is located inside the feeding bin and is laterally slidably connected.

[0004] However, during the use of the above technical solution, when the left and right blocks move, the two syringes fall simultaneously, so there is a collision with each other, which hinders the falling and reduces the work efficiency. Therefore, an automatic feeding mechanism for syringe production is needed to improve the above problem. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] In view of the shortcomings of the prior art, the present application provides an automatic loading mechanism for syringe production that realizes continuous loading of syringes through the cooperation of a slide plate, a connecting plate, a spring and a power mechanism, and drops them one by one, preventing too many syringes from colliding and affecting loading, thereby improving work efficiency and being highly practical.

[0007] (II) Technical solution

[0008] To achieve the above-mentioned purpose, the present application provides the following technical solutions: an automatic feeding mechanism for syringe production, comprising a conveying box, a working groove is provided on the conveying box, and a slide plate is slidably installed in the working groove;

[0009] The slide plate is stably slid by a limit mechanism, a connecting plate is fixedly mounted on the slide plate, two springs are symmetrically fixedly mounted on the connecting plate, and the ends of the two springs away from the connecting plate are fixedly connected to the conveying box;

[0010] The connecting plate is moved by a power mechanism, which includes a motor. Two fixed plates are symmetrically fixed on the conveying box. The motor is fixed on one of the fixed plates. A rotating shaft is fixed on the output end of the motor. The end of the rotating shaft away from the motor is rotatably connected to the other fixed plate. Two eccentric wheels are fixed on the rotating shaft. A feed hopper is connected to the conveying box, and an inclined plate is provided on the feed hopper.

[0014] Furthermore, two baffles are symmetrically fixedly mounted on the inclined plate.

[0015] Based on the above solution, an observation window is installed on the conveying box.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the present application provides an automatic feeding mechanism for syringe production, which has the following beneficial effects:

[0018] In the automatic feeding mechanism for syringe production, the syringes conveyed on the external conveyor belt roll down to the inside of the feed hopper through the inclined plate, and then fall into the inside of the conveying box through the feed hopper. By starting the motor, the motor provides power to drive the rotating shaft to rotate, and then drive the two eccentric wheels to rotate. When the longer ends of the two eccentric wheels contact the connecting plate, the two eccentric wheels squeeze the connecting plate, so that the two springs are stretched, and then drive the slide plate to move. While the slide plate moves, the syringe falls through the slide plate. When the two eccentric wheels are away from the connecting plate, the elastic force of the two springs drives the connecting plate to reset, and then drives the slide plate to reset, reciprocating motion, thereby realizing continuous feeding of the syringes, and dropping them one by one, preventing too many syringes from colliding and affecting the feeding, improving work efficiency, and having high practicality.

The two sliders 9 are symmetrically fixedly mounted at both ends of the slide plate 6. Two slide grooves are symmetrically provided on the working groove. The two sliders 9 are respectively slidably connected with the two slide grooves. The cooperation between the two sliders 9 and the two slide grooves makes the slide plate 6 more stable when moving. A connecting plate 7 is fixedly mounted on the slide plate 6. Two springs 8 are symmetrically fixedly mounted on the connecting plate 7. The ends of the two springs 8 away from the connecting plate 7 are fixedly connected to the conveying box 1.

[0028] See also Figure 1-3The connecting plate 7 is moved by a power mechanism, which includes a motor 3. Two fixed plates 2 are symmetrically fixedly installed on the conveying box 1. The motor 3 is fixedly installed on one of the fixed plates 2. A rotating shaft 4 is fixedly installed on the output end of the motor 3. The end of the rotating shaft 4 away from the motor 3 is rotatably connected to the other fixed plate 2. By starting the motor 3, the motor 3 provides power to drive the rotating shaft 4 to rotate. Two eccentric wheels 5 are fixedly installed on the rotating shaft 4, which in turn drives the two eccentric wheels 5 to rotate. When the longer ends of the two eccentric wheels 5 contact the connecting plate 7, the two eccentric wheels 5 squeeze the connecting plate 7, causing the two springs 8 to stretch. The syringes are fed into the conveying box 1 and then fed into the conveying box 1. ... and then fed into the conveying box 1 and then fed into the conveying box 1 and then fed into the conveying box 1 and then fed into the conveying box 1 and then fed into the conveying box 1 and then fed into the conveying box 1 and then fed into the conveying box 1 and then fed into the conveying box 1 and then fed into the conveying box 1 and then fed into the conveying box 1 and then fed into the conveying box 1 and then fed into the conveying box 1 and

[0029] See also Figure 1 and Figure 2 A protection mechanism is provided on one of the fixed plates 2, and the protection mechanism includes a protection cover 10. The protection cover 10 is fixedly installed on one of the fixed plates 2, and the motor 3 is located inside the protection cover 10. The installation of the protection cover 10 protects the motor 3.

[0030] See also Figure 1 and Figure 2 It should also be noted that two baffles 13 are symmetrically fixedly installed on the inclined plate 12 , and the two baffles 13 are arranged to block the syringe and prevent the syringe from escaping from the inclined plate 12 .

[0031] See also Figure 1 , Figure 2 and Figure 4 An observation window 14 is installed on the conveying box 1, and the installation of the observation window 14 facilitates timely observation of the situation inside the conveying box 1.

[0032] In summary, when the automatic feeding mechanism for syringe production is in use, the syringe transported from the external conveyor belt rolls down to the inside of the feed hopper 11 through the inclined plate 12, and the two baffles 13 block the syringe to prevent the syringe from escaping from the inclined plate 12. The syringe then passes through the feed hopper 11 and falls into the inside of the conveying box 1, and the motor 3 is started. This motor is a well-known device purchased directly from the market by technicians in this field. Here we just use it without making any structural and functional improvements to it. We will not go into details here, and the motor is provided with a control switch matched with it. The installation position of the control switch is selected according to actual use requirements to facilitate the operator to operate and control, and the motor 3 provides power to drive the rotation The moving shaft 4 rotates, thereby driving the two eccentric wheels 5 to rotate. When the longer ends of the two eccentric wheels 5 contact the connecting plate 7, the two eccentric wheels 5 squeeze the connecting plate 7, so that the two springs 8 are stretched, thereby driving the slide plate 6 to move. When the slide plate 6 moves, the syringe falls through the slide plate 6. The cooperation of the two sliders 9 makes the slide plate 6 more stable when moving. When the two eccentric wheels 5 are away from the connecting plate 7, the elastic force of the two springs 8 themselves drives the connecting plate 7 to reset, thereby driving the slide plate 6 to reset and reciprocate, thereby realizing the continuous feeding operation of the syringes, which fall one by one, preventing too many syringes from colliding and affecting the feeding, and improving the work efficiency.
