Utility Model Content

[0005] In order to prevent the container from being easily deflected on the conveyor belt, to ensure that the liquid is accurately transferred into the container and to save resources, the present application provides a filling machine.

[0006] The present application provides a filling machine, which adopts the following technical solution:

[0007] A filling machine, comprising a conveyor belt and a liquid filling device located on a frame. The conveyor belt is connected to the frame and is used to transport containers into the liquid filling device. The liquid filling device is located on one side of the conveyor belt and is connected to the frame. It further includes a contact plate and a driving mechanism. There are two contact plates, both of which are vertically arranged and are respectively located on both sides of the conveyor belt. And the mutually approaching sides of the two contact plates are in contact with the side walls of the container. Each contact plate is connected to the frame. The driving mechanism is located on the frame. The driving mechanism is connected to the contact plate and is used to drive the two contact plates to move in the mutually approaching or separating direction.

[0008] By adopting the above technical solution, the staff transports the container onto the conveyor belt and fills the container through the pipe device. When the container is skewed during transportation on the conveyor belt, the side wall of the contact plate contacts the side wall of the container. The container moves on the conveyor belt until it moves along the set path. When processing containers of different sizes, the staff adjusts the driving mechanism, so that the two contact plates move in the mutually approaching or separating direction, so as to adapt to containers of different sizes.

[0009] Preferably, a support frame is arranged on the conveyor belt. The support frame is vertically arranged and is connected to the frame. A chute is provided on the support frame. The length direction of the chute is the same as the length direction of the support frame. The driving mechanism includes two sliders, a driving source and a limiting member. The two sliders are both horizontally arranged and are located in the chute. The side wall of the slider contacts the side wall of the chute. The bottom of each slider is connected to the top of each contact plate. The driving source is located on the support frame. The driving source is connected to the slider and is used to drive the slider to move along the length direction of the chute. The limiting member is located on the support frame. The limiting member contacts the slider and is used to limit the slider to move in the vertical direction.

[0010] By adopting the above technical solution, the support frame provides support for the driving mechanism. When filling containers of different sizes, the staff starts the driving source, so that the two sliders move synchronously in the chute. Through the limiting effect of the limiting member, the two sliders move in the mutually approaching or separating direction, so as to drive the corresponding contact plates to move synchronously, so as to adapt to containers of different sizes.

[0011] Preferably, the driving source includes a cylinder and a driving rod. The cylinder is located on the frame. The cylinder body of the cylinder is connected to the frame. The piston rod of the cylinder is vertically downward. The piston rod of the cylinder is connected to the driving rod. There are two driving rods, and the two driving rods correspond to the two sliders one by one. Each driving rod is inclined and is located on the top of the slider. The bottom of each driving rod is connected to the top of the slider.

[0012] By adopting the above technical solution, the staff starts the cylinder, and the lifting of the piston rod of the cylinder drives the driving rod to move synchronously. Through the limiting member, the slider moves in a direction away from or close to each other, so that the two abutting plates move synchronously, thereby adjusting the distance between the two abutting plates to adapt to containers of different sizes.

[0013] Preferably, the limiting member includes a limiting frame which is horizontally arranged and located at the top of the supporting frame. The bottom of the limiting frame is connected to the bottom of the sliding groove, and the inner side wall of the limiting frame contacts the top of the slider.

[0014] By adopting the above technical solution, when the two sliders move driven by the driving rod, the inner side wall of the limiting block contacts the side wall of the slider, thereby limiting the slider and making the slider move along the length direction of the sliding groove, so that the slider is not easily separated from the sliding groove.

[0015] Preferably, a guiding plate and a connecting member are arranged on the side wall of the abutting plate. The guiding plate is inclined and located on the conveyor belt. The guiding plate is connected to the abutting plate, the bottom of the guiding plate contacts the conveyor belt, the connecting member is located on the machine frame, and the connecting member is connected to the guiding plate and used for making the guiding plate rotate as the abutting plate moves.

[0016] By adopting the above technical solution, the guiding plate guides the container, so that the container is not easily blocked on the conveyor belt after colliding with the abutting plate, thereby facilitating the liquid filling device to fill the container. When the abutting plate moves, the guiding plate is supported by the connecting member, so that the guiding plate always guides the container.

[0017] Preferably, a sliding rail is arranged on the machine frame, and the length direction of the sliding rail is consistent with the length direction of the conveyor belt. The connecting member includes a connecting block which is located in the sliding rail and contacts the side wall of the sliding rail, and the top of the connecting block is connected to the bottom of the guiding plate.

[0018] By adopting the above technical solution, when the guiding plate moves with the abutting plate, the connecting block moves along the length direction of the sliding rail through the sliding rail and the connecting block, so that the guiding plate rotates synchronously, so that the guiding plate always guides the container on the conveyor belt.

[0019] Preferably, an elastic member is arranged on the side wall of the guiding plate. One side of the elastic member is connected to the side wall of the guiding plate, and the other side of the elastic member is used for contacting the side wall of the container.

[0020] By adopting the above technical solution, the elastic member buffers the container, so that the container is not easily damaged due to collision with the guiding plate, reduces the wear of the container, and prolongs the service life of the container.

[0021] Preferably, a plurality of balls are provided on one side of the abutting plate close to each other, and the plurality of balls are evenly distributed along the length direction of the abutting plate. One side of each ball is connected to the side wall of the abutting plate, and the other side of each ball is used to contact the side wall of the container.

[0022] By adopting the above technical solution, the sliding friction between the container and the abutting plate is converted into rolling friction by the balls, thereby reducing the friction force between the abutting plate and the container, further reducing the wear between the container and the abutting plate, and prolonging the service life of the container.

[0023] To sum up, the present application includes at least one of the following beneficial technical effects:

[0024] 1. When the staff fills the containers on the conveyor belt, the staff adjusts the driving source. Through the limiting member, the slider moves along the length direction of the chute, thereby driving the two abutting plates to move synchronously in the direction of moving away from or approaching each other, so that the side wall of the abutting plate is always in contact with the side wall of the container, so that the container moves along the set path, so that the container is not easily deflected and the liquid is transmitted to the conveyor belt, reducing the waste of liquid;

[0025] 2. When the containers are transported on the conveyor belt, through the guiding action of the guiding plate, the containers are not easily stacked on the conveyor belt, so that after the containers pass through the guiding plate and then pass through the abutting plate, they are transported into the liquid filling device, so as to fill the containers with liquid;

[0026] 3. One side of the ball is connected to the side wall of the abutting plate, and the other side of the ball is in contact with the side wall of the container. The ball converts the sliding friction between the side wall of the container and the side wall of the abutting plate into rolling friction, thereby reducing the wear between the container and the abutting plate and prolonging the service life of the container.

Detailed implementation manners

[0031] The present application will be further described in detail below with reference to all the attached drawings.

[0032] An embodiment of the present application discloses a filling machine.

[0033] Referring to Figure 1 and Figure 2 , a filling machine includes a frame 1, a conveyor belt 11 and a liquid filling device 2. The conveyor belt 11 and the liquid filling device 2 are both located on the frame 1. The conveyor belt 11 is fixedly connected to the frame 1. The conveyor belt 11 is used to transport the container 12, so that it is easily transported under the liquid filling device 2. Then, through the liquid filling device 2, the intestinal bacteria culture medium is transported into the container 12. The liquid filling device 2 includes a syringe barrel 21 and a syringe needle 22. The vertically arranged syringe barrel 21 is located at the top of the frame 1 and is fixedly connected to the frame 1. The syringe needle 22 is located at the top of the conveyor belt 11, and the needle hole of the syringe needle 22 faces the container 12.

[0034] Referring to Figure 2 and Figure 3 , a support frame 4, a contact plate 3 and a driving mechanism 5 are installed on the conveyor belt 11. The vertically arranged support frame 4 is in the shape of a gantry, and the bottom of the support frame 4 is fixedly connected to the frame 1. A chute 41 is opened at the top of the support frame 4. The horizontally arranged chute 41 is in a T shape, and the length direction of the chute 41 is the same as the length direction of the support frame 4. There are two contact plates 3, and both contact plates 3 are located at the bottom of the support frame 4. The two contact plates 3 are respectively located on both sides of the conveyor belt 11. The side wall of each vertically arranged contact plate 3 contacts the side wall of the container 12, and the top of the contact plate 3 contacts the inner side wall of the support frame 4. A plurality of balls 31 are installed on one side of each contact plate 3 close to the container 12. The plurality of balls 31 are evenly distributed along the length direction of the contact plate 3. One side of each ball 31 is rotatably connected to the side wall of the contact plate 3, and the other side of each ball 31 contacts the side wall of the container 12, so as to reduce the wear of the contact plate 3 on the container 12.

[0035] The driving mechanism 5 includes two sliders 51, a driving source 52 and a limiting member. The driving source 52 includes a cylinder 521 and a driving rod 522, and the limiting member includes a limiting frame 53. The two horizontally arranged sliders 51 are both located in the chute 41, and the side walls of the two sliders 51 are in contact with the side walls of the chute 41. Each slider 51 corresponds to each abutting plate 3, and the bottom of the slider 51 is fixedly connected to the top of the abutting plate 3. The cylinder 521 is located on the top of the conveyor belt 11, the cylinder block of the cylinder 521 is fixedly connected to the frame 1, the piston rod of the cylinder 521 is arranged vertically downward, the piston rod of the cylinder 521 is hinged to the driving rod 522. There are two driving rods 522, and the two driving rods 522 are both located on the top of the slider 51. Each driving rod 522 is inclined and located on the top of the slider 51. Each driving rod 522 corresponds to each slider 51, and the bottom of each driving rod 522 is hinged to the top of the slider 51. There are two horizontally arranged limiting frames 53, and the two limiting frames 53 are respectively located on both sides of the driving rod 522. Each limiting member is in a gantry shape and located on the top of the support frame 4. The bottom of the limiting frame 53 is fixedly connected to the bottom of the chute 41, and the inner side wall of the limiting frame 53 is in contact with the top of the slider 51, so that the slider 51 moves on the inner side wall of the limiting frame 53.

[0036] The support frame 4 provides support for the driving mechanism 5. When the container 12 is transported on the conveyor belt 11, the staff adjusts the cylinder 521. The lifting and lowering of the piston rod of the cylinder 521 drives the two driving rods 522 to move synchronously. Through the limiting action of the limiting frame 53, the two sliders 51 move along the length direction of the chute 41, so as to drive the two abutting plates 3 to move in the direction of approaching or separating from each other, thereby adjusting the distance between the two abutting plates 3. The container 12 is driven by the abutting plates 3 and transported along the set path, so that the container 12 is not easily deflected on the conveyor belt 11. When the injection needle 22 injects the container 12, the liquid is not easily transmitted outside the container 12 and causes the liquid to be transmitted onto the conveyor belt 11, thereby reducing the waste of liquid and saving resources.

[0037] Refer to Figure 2 and Figure 3, a slide rail 13, a connecting member and a guide plate 14 for guiding the container 12 are arranged on the rack 1. There are two horizontally arranged slide rails 13, and the two slide rails 13 are respectively located on both sides of the conveyor belt 11. The side wall of each slide rail 13 is detachably connected to the side wall of the conveyor belt 11 by bolts. The connecting member includes a connecting block 6. There are two horizontally arranged connecting blocks 6, and the two connecting blocks 6 correspond to the two slide rails 13 one by one. Each connecting block 6 is located in the slide rail 13, and the side wall of the connecting block 6 contacts the side wall of the slide rail 13. There are two guide plates 14, and the two guide plates 14 correspond to the two abutting plates 3 one by one. One side of each vertically arranged guide plate 14 is hinged to the abutting plate 3, and the other side of each guide plate 14 is hinged to the connecting block 6. Elastic members 7 are installed on the side walls of the two guide plates 14 close to each other. The elastic members 7 are made of rubber materials. One side of the elastic member 7 is bonded to the guide plate 14, and the other side of the elastic member 7 is used to contact the side wall of the container 12, so as to reduce the wear of the container 12 and improve the quality of the container 12.

[0038] When the container 12 is transported on the conveyor belt 11, the guide plate 14 contacts the container 12, so as to guide the container 12, making it not easy for the container 12 to accumulate on the conveyor belt 11. When the two abutting plates 3 move in the direction of moving away from or approaching each other, through the slide rail 13 and the connecting block 6, the guide plate 14 rotates synchronously, so that the container 12 can be transported to the lower part of the injection needle 22 through the conveyor belt 11.

[0039] The implementation principle of an infusion filling machine in an embodiment of the present application is as follows: when the container 12 is transported on the conveyor belt 11, after the container 12 passes through the guide plate 14 and the abutting plate 3 in sequence, it is transported to the lower part of the injection needle 22. Through the limiting action of the abutting plate 3, the container 12 is transported along the set path, so that the liquid is transported into the container 12, making it not easy for the liquid in the injection needle 22 to separate from the container 12 and drip on the conveyor belt 11, reducing the waste of liquid and saving resources.

[0040] When transporting containers 12 of different sizes, the staff adjusts the air cylinder 521. The lifting of the piston rod of the air cylinder 521 drives the two driving rods 522 to lift synchronously, so as to drive the two sliders 51 to move synchronously. Through the limiting action of the limiting frame 53, the two sliders 51 move synchronously along the length direction of the chute 41, so as to drive the two abutting plates 3 to move in the direction of approaching and moving away from each other, so as to adjust the distance between the two abutting plates 3, so that containers 12 of different sizes can be transported to the set position along the set path, so as to adapt to containers 12 of different sizes and expand the scope of use.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
