Description

Technical Field

[0001] This utility model relates to the field of syringe manufacturing equipment technology, and in particular to an automatic syringe feeding mechanism. Background Technology

[0002] After syringes are manufactured, they need to be packaged for subsequent production and storage. Before packaging, the syringes need to be fed into a feeding mechanism, which transports them to the packaging station for packaging. For example, Chinese patent CN 222743626 U discloses an automatic feeding mechanism for syringe production. In this device, syringes conveyed on an external conveyor belt roll down an inclined plate into the feed hopper, and then fall into the conveyor box. By starting a motor, the motor provides power to drive a rotating shaft to rotate, which in turn drives two eccentric wheels to rotate. When the longer ends of the two eccentric wheels contact the connecting plate, the pressure of the two eccentric wheels on the connecting plate stretches two springs, which in turn moves a sliding plate. As the sliding plate moves, the syringes fall onto it. When the two eccentric wheels move away from the connecting plate, the elastic force of the two springs resets the connecting plate, which in turn resets the sliding plate. This reciprocating motion enables continuous feeding of syringes. Although the device can deliver syringes for feeding, there is a certain chance that the syringes will over-stacking during the feeding process, which will require the device to be stopped for adjustment and reduce the production efficiency of the device. Utility Model Content

[0003] This invention proposes an automatic syringe feeding mechanism to solve the problem of excessive stacking of syringes when existing devices deliver syringes.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic syringe feeding mechanism, comprising a conveying component and a feeding component. The conveying component includes a housing portion and multiple drive rollers. The multiple drive rollers are rotatably connected to the housing portion along an axis parallel to the horizontal plane. A conveyor belt is sleeved between the multiple drive rollers. Multiple limiting strips are adhered to the outer circumferential surface of the conveyor belt. A positioning groove for accommodating syringes is formed between two adjacent limiting strips. A placement cavity for accommodating syringes is formed on the feeding component, and the top of the feeding component is open to form a discharge hole for discharging syringes. The discharge hole is located above the conveyor belt and communicates with the placement cavity.

[0005] Preferably, a second baffle is fixedly connected to the top of the housing portion at an angle, and the second baffle is positioned above the conveyor belt.

[0006] Preferably, the housing portion includes a base frame, the transmission roller is rotatably connected to the inside of the base frame, and a first motor is fixedly connected to the outside of the base frame, the output end of the first motor being connected to the transmission roller.

[0007] Preferably, the feeding component includes a feeding hopper, the placement cavity is formed inside the feeding hopper, and an inclined plate is fixedly connected inside the placement cavity at an inclination, and the discharge hole is formed between the inner wall of the placement cavity and the inclined plate.

[0008] Preferably, a second motor is fixedly connected to the top of the feed hopper, and a stirring rod is connected to the output end of the second motor. The stirring rod is located inside the placement cavity.

[0009] Preferably, connecting plates are fixedly connected to both sides of the symmetrical feed hopper, and side frames are fixedly connected to both sides of the symmetrical base frame along the length direction. The connecting plates are slidably connected to the inside of the side frames, and a limiting rod is screwed onto the outside of the side frames. The free end of the limiting rod extends into the inside of the side frames and abuts against the connecting plates. A side groove matching the limiting rod is recessed on the connecting plates.

[0010] Preferably, a first baffle is fixedly connected to the top of the base frame, the feed hopper is located between the first baffle and the second baffle, and the bottom of both the first baffle and the second baffle has a groove that matches the limiting strip.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows: (1) This application is equipped with a transmission roller, a conveyor belt and a limiting strip. When the syringe falls onto the conveyor belt, the conveyor belt and the limiting strip work together to make the syringe position in the positioning groove between two adjacent limiting strips, so that the syringes move one by one, avoiding multiple syringes from overlapping in one place, so that the device does not need to be stopped for adjustment, thereby improving the production efficiency of the device.

[0012] (2) When the syringe moves with the cooperation of the conveyor belt and the limiting strip, the second baffle blocks the syringes that are accidentally stacked, thereby allowing the syringes to spread out and the conveyor belt to move the syringes, further improving the production efficiency of the device.

[0013] (3) By setting up a side frame, a limiting rod and a connecting plate, the connecting plate is clamped by the limiting rod during use, so that the height of the feed hopper can be adjusted, thereby making it easier for the feed hopper to discharge the syringe, avoiding the syringe from getting stuck between the feed hopper and the conveyor belt, and further improving the efficiency of the device in conveying the syringe.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1-5 As shown, an automatic syringe feeding mechanism includes a conveying component 1 and a feeding component 2. The conveying component 1 includes a housing part and multiple drive rollers 19. The multiple drive rollers 19 are rotatably connected to the housing part along an axis parallel to the horizontal plane. A conveyor belt 17 is sleeved between the multiple drive rollers 19. Multiple limiting strips 18 are bonded to the outer peripheral surface of the conveyor belt 17. A positioning groove for accommodating syringes is formed between two adjacent limiting strips 18. A placement cavity for accommodating syringes is formed on the feeding component 2, and the top of the feeding component 2 is open to form a discharge hole for discharging syringes. The discharge hole is located above the conveyor belt 17 and is connected to the placement cavity.

[0018] With the above technical solution, before packaging the syringes, the syringes are inserted into the placement cavity on the feeder 2. After the syringes are inserted, they slide onto the conveyor belt 17 through the discharge hole. The syringes slide into the positioning groove through the limiting strip 18 on the conveyor belt 17. The transmission roller 19 rotates, causing the conveyor belt 17 to rotate. The conveyor belt 17 then moves the limiting strip 18, allowing the syringes to move one by one to the subsequent workstation for packaging, thus improving packaging efficiency.

[0019] When the conveyor belt 17 moves the syringes, to avoid excessive stacking of the syringes, such as Figures 1-4 As shown, a second baffle 13 is fixedly connected to the top of the housing part at an angle, and the second baffle 13 is located above the conveyor belt 17.

[0020] In this embodiment, when the conveyor belt 17 and the limiting strip 18 move the syringes, the second baffle 13 cooperates to block the syringes that are stacked too high, causing the stacked syringes to slide down, making it easier for workers to pick up the syringes for packaging.

[0021] Specifically, in one embodiment, regarding the aforementioned housing portion, such as Figures 1-4 As shown, the housing includes a base frame 11, a transmission roller 19 is rotatably connected to the inside of the base frame 11, and a first motor 110 is fixedly connected to the outside of the base frame 11. The output end of the first motor 110 is connected to the transmission roller 19.

[0022] In this embodiment, the transmission roller 19 is supported by the base frame 11. When it is necessary to move the syringe, the first motor 110 works to drive the transmission roller 19 to rotate, which in turn drives the conveyor belt 17 to rotate, thereby allowing the conveyor belt 17 to move the syringe.

[0023] Specifically, in one embodiment, regarding the aforementioned feeder 2, as... Figure 1 , Figure 2 and Figure 5 As shown, the feeding component 2 includes a feeding hopper 21, a placement cavity is formed inside the feeding hopper 21, and an inclined plate 24 is fixedly connected inside the placement cavity at an inclination. A discharge hole is formed between the inner wall of the placement cavity and the inclined plate 24.

[0024] In this embodiment, before conveying the syringe, the syringe is put into the feed hopper 21. After the syringe enters the feed hopper 21, it is conveyed to the conveyor belt 17 through the discharge hole by the inclined plate 24, and then the syringe can be moved by the conveyor belt 17.

[0025] To improve the ejection efficiency of the syringe, such as Figure 1 , Figure 2 and Figure 5As shown, a second motor 25 is fixedly connected to the top of the feed hopper 21, and a stirring rod 26 is connected to the output end of the second motor 25. The stirring rod 26 is located inside the placement cavity.

[0026] In this embodiment, after the syringe is added into the placement cavity inside the feed hopper 21, the second motor 25 drives the stirring rod 26 to rotate, and the stirring rod 26 flips the syringe, making it easier for the syringe to be discharged through the discharge hole, thus avoiding the syringe from accidentally getting stuck and being unable to be discharged.

[0027] To adjust the height of the feed hopper 21 so that it can easily discharge the syringe, such as... Figures 1-5 As shown, the feed hopper 21 is symmetrically connected to both sides of the connecting plate 22, and the base frame 11 is symmetrically connected to both sides of the side frame 15 along the length direction. The connecting plate 22 is slidably connected to the inside of the side frame 15, and the side frame 15 is screwed to the outside of the limiting rod 16. The free end of the limiting rod 16 extends into the inside of the side frame 15 and abuts against the connecting plate 22. The connecting plate 22 is recessed to form a side groove 23 that matches the limiting rod 16.

[0028] In this embodiment, before inserting the syringe into the feed hopper 21, the feed hopper 21 is pulled, causing the feed hopper 21 to move the connecting plate 22 relative to the side frame 15 until the position of the feed hopper 21 is adjusted. Then, the limiting rod 16 on the side frame 15 is rotated, so that the free end of the limiting rod 16 clamps the connecting plate 22, thereby fixing the position of the connecting plate 22 and the feed hopper 21, making it easier for the syringe to be discharged from the gap between the feed hopper 21 and the conveyor belt 17.

[0029] When the syringe is discharged from the feed hopper 21, to prevent the syringe from being accidentally discharged from the side of the conveyor belt 17 near the feed hopper 21, such as Figures 1-4 As shown, a first baffle 12 is fixedly connected to the top of the base frame 11, and the feed hopper 21 is located between the first baffle 12 and the second baffle 13. The bottom of the first baffle 12 and the second baffle 13 both form a groove 14 that matches the limiting strip 18.

[0030] In this embodiment, when the feed hopper 21 discharges the syringe, the base frame 11 supports the first baffle 12, and the first baffle 12 blocks one side of the conveyor belt 17, thereby preventing the syringe from being discharged accidentally.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
