Description

Technical Field

[0001] The invention discloses an automatic filling mechanism for liquid medical consumables, belonging to the technical field of medical consumables production. Background Art

[0002] Filling equipment is mainly a type of packaging machine. From the perspective of material packaging, it can be divided into liquid filling machines, paste filling machines, powder filling machines, and granule filling machines; from the perspective of the degree of production automation, it can be divided into semi-automatic filling machines and fully automatic filling production lines. Filling equipment is also used in the pharmaceutical field.

[0003] The patent with announcement number CN112810852B discloses a rotary equal-volume filling equipment for pharmaceutical processing, including: a shell, a supporting mechanism is provided at the bottom of the shell, and a horizontal adjustment member is provided on the left and right sides of the bottom of the supporting mechanism; a driving drum is rotatably connected to the top of the shell, and a medicine barrel is provided on the shell above the driving drum; two medicine outlet pipes are connected to the bottom of the medicine barrel, and a push-type valve and a flow limiting valve are installed on the two medicine outlet pipes, and a top pressure roller is installed at the bottom of the pressing column of each push-type valve; rectangular notches are opened on the left and right sides of the top surface of the shell, and a conveyor belt is installed in each rectangular notch; a control box is installed on the front side of the upper part of the shell through a support.

[0004] The above patent sets up two conveyor belts, one of which controls the feeding of medicine bottles. When the medicine bottles rotate synchronously with the circular driving plate, they are filled three times in succession and sent out from the other conveyor belt. In this way, the filling production of medicinal materials can be completed. Although the patent can realize automatic filling control, the filling method of one conveyor belt feeding and one conveyor belt discharging is still subject to relatively large limitations in filling efficiency. Moreover, the same medicine bottle is filled three times, which not only increases the duration of the filling process, but also the medicine bottle is already filled with liquid medicinal materials during the second and third fillings. When the circular driving plate drives the medicine bottle to stop rotating, the medicine bottle has inertia, causing the liquid medicinal materials inside it to flow, especially during the third filling and discharging, which may cause liquid to flow out of the medicine bottle.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] like Figure 1-Figure 7As shown, an automatic filling mechanism for liquid medical consumables includes a frame 7 and a medicine barrel 1. The medicine barrel 1 is located above the frame 7, and four automatic liquid discharge pipes 3 are arranged at the bottom thereof. When the bottle body 2 reaches below the automatic liquid discharge pipe 3, it will automatically open and inject the liquid medical consumables in the medicine barrel 1 into the bottle body 2, and automatically close after the filling is completed. This principle and structure belong to the prior art and will not be repeated here. A disc 5 is rotatably arranged in the middle of the frame 7, and an annular slide 4 is arranged on the frame 7. The annular slide 4 is arranged around the outer side of the disc 5. Two push blocks 17 are arranged on the outer circumference of the disc 5. The push blocks 17 are located in the annular slide 4 for pushing the bottle body 2. Two groups of feeding devices 6 are arranged on the outer side of the frame 7. The two groups of feeding devices 6 are symmetrically distributed at 180° with the disc 5 as the center. The feeding device 6 consists of a feeding conveyor belt 10 and a first support frame 11. The feeding conveyor belt 10 is installed on the first support frame 11 and can transport the bottle body 2 to the annular slide 4. The discharging device 9 is provided on both sides of the device 6. The discharging device 9 is used to send out the filled bottle body 2. It is mainly composed of a discharging conveyor belt 14 and a second support frame 15. The discharging conveyor belt 14 is installed on the second support frame 15. One end of the first support frame 11 and the second support frame 15 are connected with the annular slide 4. The discharging conveyor belt 14 and the feeding conveyor belt 10 are separated from the annular slide 4 by one end, which can simplify the installation structure and working control method of the conveyor belt. The angle between the two groups of discharging devices 9 is 60°. The lower end of the frame 7 is provided with a power device 12. The power device 12 can drive the disc 5 to reciprocate and circulate between the two groups of discharging devices 9. In this way, the bottle body 2 on the feeding conveyor belt 10 can be pushed to the connection between the two groups of discharging devices 9 and the annular slide 4 in turn after entering the annular slide 4, so that four filling positions can be formed on the frame 7, two of which are filled at the same time, which can effectively shorten the time of the filling process and improve the filling efficiency.

[0025] The power device 12 is composed of a motor 36, a driving gear 37, a driven gear 35, a transmission gear 33 and a bracket 13. The bracket 13 is fixedly connected to the frame 7. The driving gear 37 and the driven gear 35 are rotatably mounted on the bracket 13, and the driving gear 37 is fixedly connected to the output shaft of the motor 36. The driving gear 37 meshes with the driven gear 35 for transmission. A transmission shaft 32 is connected between the transmission gear 33 and the disc 5. The driving gear 37 and the driven gear 35 are both provided with a plurality of transmission columns 34 distributed at equal angles. The transmission gear 33 can mesh with the transmission column 34 on the driving gear 37 for transmission or mesh with the transmission column 34 on the driven gear 35 for transmission. When the motor 36 drives the driving gear 37 to rotate, the driven gear 35 is rotated. When the transmission column 34 on the driven gear 35 drives When the driven transmission gear 33 rotates, the transmission column 34 on the driving gear 37 does not mesh with the transmission gear 33, so that the disc 5 first rotates counterclockwise by a certain angle and pushes a bottle body 2 to one of the groups of discharging devices 9. After the bottle body 2 reaches the specified position, the transmission column 34 on the driven gear 35 just disengages from the meshing with the transmission gear 33, and the transmission column 34 on the driving gear 37 just meshes with the transmission gear 33, thereby driving the disc 5 to rotate clockwise. At the same time, the feeding conveyor 10 feeds the next bottle body 2 into the annular slide 4, and then the push block 17 can push the bottle body 2 to another group of discharging devices 9 when the disc 5 rotates, so that the bottle body 2 transported by the feeding conveyor 10 is pushed to two positions in turn for filling, which effectively shortens the waiting time for filling.

[0026] Since the second support frame 15 is provided with a stopper 18, when the bottle body 2 hits the stopper 18, it can reach the filling position, and the automatic discharge pipe 3 controls the circulation of liquid medical consumables to start filling. Since the disc 5 is also provided with a protrusion 8, the protrusion 8 is located in the annular slideway 4 between the two groups of discharge devices 9 on the same side of the two groups of feeding devices 6, and the protrusion 8 also rotates synchronously with the disc 5. Both sides of the protrusion 8 are provided with arc-shaped contact surfaces 16. When the arc-shaped contact surface 16 contacts the bottle body 2, the automatic discharge pipe 3 is automatically closed and the filling is completed. In this process, the flow volume and flow time of the automatic discharge pipe 3 are set to meet the filling requirements, so that the next bottle body 2 is in the process of feeding, and the previous bottle body 2 is filled synchronously, which can further shorten the filling time. The filled bottle body 2 will be pushed by the protrusion 8. In order to make the bottle body 2 move only toward the second support frame 15, a movable material blocking device 19 is set on the frame 7. When the bottle body 2 slides toward the block 18, the movable material blocking device 19 does not block the sliding of the bottle body 2. After the filling is completed, when the protrusion 8 moves toward the bottle body 2, the movable material blocking device 19 exerts a blocking effect on the bottle body 2, so that it is restricted between the movable material blocking device 19 and the block 18. The thrust generated by the arc-shaped contact surface 16 on the bottle body 2 is used to push the filled bottle body 2 into the second support frame 15, thereby completing automatic discharging.

[0027] The movable material blocking device 19 is composed of a blocking bar 21, an upper gear 23, a lower gear 25, a connecting shaft 24 and an arc-shaped rack 29. The two ends of the connecting shaft 24 are fixedly connected to the upper gear 23 and the lower gear 25 respectively, and are rotatably mounted on the frame 7. The blocking bar 21 is slidably connected to the second support frame 15, and the side of the blocking bar 21 is provided with a toothed groove 22 meshing with the upper gear 23. The lower gear 25 meshes with the arc-shaped rack 29 for transmission. A protrusion 31 is provided at one end of the arc-shaped rack 29. The arc-shaped rack 29 is concentrically arranged with the annular slide 4, and a positioning block 30 is provided below the arc-shaped rack 29. A groove 30 cooperating with the positioning block 30 is provided on the frame 7. 9, a shift block 20 is provided at one end of the push block 17 away from the disc 5, and a first guide slot 38 and a second guide slot 40 for sliding the arc-shaped rack 29 and the shift block 20 are respectively provided on the frame 7, one end of the stop bar 21 extends into the annular slide 4, and a reset member is provided at the other end, the reset member includes a spring 26, a guide rod 28 and a fixed block 27, the fixed block 27 is fixedly connected to the second support frame 15, one end of the guide rod 28 passes through the fixed block 27 and is fixedly connected to the stop bar 21, the spring 26 is sleeved on the outer side of the guide rod 28, and the two ends are respectively against the fixed block 27 and the stop bar 21, when the push block 17 pushes the bottle body 2 to slide along the annular slide 4 toward the stop block 1 8, the shift block 20 slides along the second guide slot 40 and hits the protrusion 31, so that the arc-shaped rack 29 rotates a certain angle with the disk 5 as the center, and the groove 39 and the first guide slot 38 can guide the sliding of the arc-shaped rack 29. At this time, the lower gear 25 rotates and drives the upper gear 23 to rotate synchronously, and then the blocking bar 21 is driven by the upper gear 23 to slide along the second support frame 15 and compress the spring 26. The blocking bar 21 does not block the sliding of the bottle body 2. When the disk 5 drives the push block 17 to rotate in the opposite direction, the protrusion 31 is no longer subjected to the thrust. At this time, the blocking bar 21 is reset under the action of the spring 26, so that the upper gear 2 3 drives the lower gear 25 to rotate in the opposite direction, so that the arc-shaped rack 29 is reset, and the bottle body 2 is restricted between the stopper 18 and the stopper bar 21 to ensure that when the protrusion 8 applies a force to the bottle body 2, the bottle body 2 will not slide along the annular slideway 4, so that it is automatically sent out from the discharging device 9. In this way, the entire structure can realize automatic filling. The bottle body 2 after filling moves a small distance, and then it is driven by the discharging conveyor belt 14 to move synchronously, which can effectively prevent liquid medical consumables from flowing out of the bottle body 2, and the four filling positions can be filled synchronously in pairs. The disc 5 rotates continuously and uninterruptedly, which effectively shortens the waiting time for filling and greatly improves the production efficiency.
