Detailed implementation mode

[0023] The present utility model will be further described below in conjunction with the accompanying drawings:

[0024] In the paragraphs of the detailed description, the orientation nouns involved are only for the convenience of those skilled in the art to understand the technical solutions recorded in this application according to the visual orientation shown in the accompanying drawings. Unless otherwise clearly specified and limited, the terms "set", "installed", "connected", etc. should be understood in a broad sense. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0025] Such as Figure 1 And Figure 2As shown in the figure, a packaging device for pre-filled syringes includes a machine body 1. A conveyor belt 103 is installed on the machine body 1. A driving motor 101 is fixedly installed on the side of the machine body 1. The output shaft of the driving motor 101 is matched with the conveyor belt 103. Pre-filled syringes 5 are placed on the conveyor belt 103. Legs 102 are fixedly connected to the bottom of the machine body 1. A pushing mechanism 2 is fixedly arranged on one side of the machine body 1, and a follow-up expansion mechanism 3 is fixedly arranged on the other side of the machine body 1. By setting the follow-up expansion mechanism 3, the expansion block 304 can move backward and open as the pull plate 403 descends, making the opening of the packaging bag larger, which is beneficial for the push claw 203 to smoothly push the pre-filled syringe 5 into the packaging bag. On the other side of the follow-up expansion mechanism 3, an opening mechanism 4 is fixedly arranged. By setting the pushing mechanism 2 and the opening mechanism 4, the packaging bag is opened by negative pressure, and the push claw 203 is used to push the pre-filled syringe 5 into the packaging bag from the opening, and then the packaging bag is sealed by the hot melt strip 401C to realize automatic packaging operation, greatly reducing the labor intensity of workers.

[0026] The pushing mechanism 2 includes a mounting frame 201. The mounting frame 201 is fixedly connected to the left side wall of the machine body 1. An electric push rod 202 is fixedly connected to the mounting frame 201, and a push claw 203 is fixedly connected to the electric push rod 202. The driving motor 101 drives the conveyor belt 103 to rotate. When the pre-filled syringe 5 is sent to the predetermined position, the driving motor 101 stops rotating. The electric push rod 202 extends the push claw 203 to push the pre-filled syringe 5 into the packaging bag for packaging operation. The push claw 203 retracts, and the driving motor 101 continues to drive the conveyor belt 103 to rotate to convey the pre-filled syringe 5 to be packaged forward.

[0027] As Figure 3 and Figure 4 As shown in the figure, the follow-up expansion mechanism 3 includes a fixed box 301. The fixed box 301 is fixedly connected to the right side wall of the machine body 1. A first chute 301A is fixedly opened on the side wall of the fixed box 301, and multiple groups of second chutes 301B are fixedly opened on the top of the fixed box 301. A sliding rod 303 is slidably connected to the first chute 301A. Multiple groups of mounting sliding frames 302 are fixedly connected to the sliding rod 303. The mounting sliding frames 302 are slidably connected to the second chutes 301B. A third chute 302B is fixedly opened on the top of the mounting sliding frame 302, and a sliding hole 302A is fixedly opened in the middle of the mounting sliding frame 302. Since the sliding rod 303 is connected to the limiting rod 403B through the connecting rod two 6, when the electric push rod 402 drives the pull plate 403 to move upward, the mounting sliding frame 302 slides backward on the second chute 301B, making the expansion block 304 approach the opening mechanism 4. When the electric push rod 402 drives the pull plate 403 to move downward, the mounting sliding frame 302 slides forward on the second chute 301B, making the expansion block 304 move away from the opening mechanism 4.

[0028] As Figure 5 and Figure 6As shown in the figure, a slider 305 is slidably connected to the chute three 302B. A swivel base 305A is fixedly connected to the top of the slider 305. An expansion block 304 is fixedly connected to the top of the swivel base 305A. A limit push rod 307 is slidably connected to the sliding hole 302A. A connecting block 307B is fixedly connected to the rear end of the limit push rod 307. One ends of two connecting rods one 306 are rotatably connected to both sides of the connecting block 307B, and the other ends of the connecting rods one 306 are rotatably connected to the swivel base 305A. A pressing head 307A is fixedly connected to the rear part of the connecting block 307B. A compression spring 308 is fixedly connected to the front part of the connecting block 307B, and the other end of the compression spring 308 is fixedly connected to the mounting slide 302. Under the elastic force of the compression spring 308, the limit push rod 307 moves backward relative to the mounting slide 302, and drives the slider 305 to contract towards the middle of the mounting slide 302.

[0029] As Figure 7 and Figure 8 As shown in the figure, the opening mechanism 4 includes a fixed frame 401. The fixed frame 401 is fixedly connected to the right side wall of the fixed box 301. A chute four 401B is fixedly opened on the side wall of the fixed frame 401. A negative pressure suction port one 401D and a hot melt strip 401C are fixedly arranged on the fixed frame 401. The hot melt strip 401C is located in front of the negative pressure suction port one 401D. A convex block 401A is fixedly connected to the front part of the fixed frame 401. An electric push rod two 402 is fixedly connected to the top of the fixed frame 401. A pull plate 403 is fixedly connected to the push rod of the electric push rod two 402. A limit rod 403B is fixedly connected to the side wall of the pull plate 403. The limit rod 403B is slidably connected to the chute four 401B. A negative pressure suction port two 403A and a mounting groove 403C are fixedly arranged at the bottom of the pull plate 403. The mounting groove 403C is located in front of the negative pressure suction port two 403A. A spring 404A is fixedly connected to the bottom of the mounting groove 403C. The other end of the spring 404A is fixedly connected to a pressing strip 404. The pressing strip 404 is slidably connected to the mounting groove 403C.

[0030] In the working state, the packaging bag is placed on the negative pressure suction port one 401D. The electric push rod two 402 drives the pull plate 403 to move downward, so that the negative pressure suction port two 403A contacts the packaging bag. Then the electric push rod two 402 drives the pull plate 403 to move upward, and the opening of the packaging bag is also opened. When the pre-filled needle 5 enters the packaging bag, the electric push rod two 402 drives the pull plate 403 to move downward again. At this time, the pressing strip 404 presses the opening of the packaging bag onto the hot melt strip 401C, and the hot melt strip 401C is electrified to seal the opening of the packaging bag. Thus, a set of packaging operations for the pre-filled needle 5 is completed.

[0031] The negative pressure suction port II 403A cooperates with the negative pressure suction port I 401D, the pressure strip 404 cooperates with the hot melt strip 401C, the convex block 401A cooperates with the pressure head 307A, and both sides of the limit rod 403B are rotatably connected with the connecting rod II 6. The other end of the connecting rod II 6 is rotatably connected with the sliding rod 303. By setting the connecting rod II 6, the up-and-down movement of the pull plate 403 is linked with the front-and-back movement of the installation sliding frame 302. When the pull plate 403 moves downward, the installation sliding frame 302 moves away from the opening mechanism 4. When the pull plate 403 moves upward, the installation sliding frame 302 moves closer to the opening mechanism 4 and cooperates with the opening mechanism 4 to expand the opening of the packaging bag.

[0032] Working principle:

[0033] 1. The pre-filled needle 5 is conveyed to the designated position by the conveyor belt 103. The worker places the packaging bag on the opening mechanism 4, and the electric push rod II 402 extends downward to pull the pull plate 403.

[0034] 2. The negative pressure suction port I 401D sucks the bottom of the packaging bag, and the negative pressure suction port II 403A sucks the top of the packaging bag. The electric push plate II 402 pulls up the pull plate 403, and the opening of the packaging bag is opened.

[0035] 3. While the pull plate 403 moves upward, driven by the connecting rod II 6, the installation sliding frame 302 gradually approaches the opening mechanism 4 on the chute II 301B, the expansion block 304 gradually extends into the already opened packaging bag, and the pressure head 307A begins to contact the convex block 401A.

[0036] 4. The limit push rod 307 continues to squeeze the compression spring 308, driving the slider 305 to slide on the chute III 302B, and the expansion blocks 304 also move away from each other, completely expanding the opening of the packaging bag.

[0037] 5. The electric push rod I 202 extends the push claw 203 to push the pre-filled needle 5 into the packaging bag. The electric push rod I 202 retracts, the electric push rod II 402 presses down the pull plate 403, the installation sliding frame 302 moves away from the opening mechanism 4, and the hot melt strip 401C is electrified to cooperate with the pressure strip 404 to seal the packaging bag.

[0038] By setting the follow-up expansion mechanism 3 in the utility model, the expansion block 304 can move backward and open as the pull plate 403 descends, making the opening of the packaging bag larger, which is beneficial for the push claw 203 to smoothly push the pre-filled needle 5 into the packaging bag. By setting the pushing mechanism 2 and the opening mechanism 4, the packaging bag is opened by negative pressure, the pre-filled needle 5 is pushed into the packaging bag from the opening by the push claw 203, and then the packaging bag is sealed by the hot melt strip 401C, realizing automatic packaging operation and greatly reducing the labor intensity of workers.
