Description

Technical Field

[0001] The utility model belongs to the technical field of filling machines, in particular to a filling machine for injectable ceftiofur sodium freeze-dried powder. Background Art

[0002] Ceftiofur Sodium Lyophilized Powder for Injection is suitable for severe systemic infections and respiratory, digestive, urogenital and other inflammations in livestock and poultry caused by various reasons. Ceftiofur Sodium is made into lyophilized powder and used for injection. The production process is freeze-dried under vacuum and low temperature. After freeze-drying, a filling machine is usually used to quantitatively package the Ceftiofur Sodium Lyophilized Powder for Injection. The quantitative quantity is accurate, the packaging error is small, and the packaging amount is easy to adjust.

[0003] A Chinese patent document (authorization announcement number CN220199643U) discloses a filling machine for freeze-dried powder of ceftiofur sodium for injection, which includes a conveyor belt, a fixed block is fixedly connected to the front of the top of the conveyor belt, a conveying hole is opened in the middle of the fixed block, a fixed rod is fixedly connected to the back of one side of the conveyor belt, a storage tank is fixedly connected to the top of the front of the fixed rod, and a filling rod is fixedly connected to the bottom of the storage tank.

[0004] It can be seen that although the patent document cited above is provided with a fixing device to completely surround the bottle mouth of the ceftiofur sodium freeze-dried powder filling bottle when filling the ceftiofur sodium freeze-dried powder filling bottle, so that the external wind force does not affect the outputted ceftiofur sodium freeze-dried powder for injection, thereby ensuring the filling quality of ceftiofur sodium freeze-dried powder for injection, but when the ceftiofur sodium freeze-dried powder filling bottle is transported and loaded and unloaded through the conveyor belt, due to the lack of a protective mechanism, the ceftiofur sodium freeze-dried powder filling bottle is easy to fall from the conveyor belt, thereby causing contamination of the filling bottle.

[0010] As a preferred embodiment, the structure of the unloading assembly is the same as that of the loading assembly, and an arc-shaped guide plate is provided at the top of the unloading assembly.

[0011] As a preferred embodiment, an arc-shaped baffle plate is installed on the top of the filling station in contact with the outer wall of the conveying tray.

[0012] As a preferred embodiment, two sliding bars are provided on the opposite side of the fixing frame and the filling station, and the outer walls of the two sliding bars respectively penetrate the top of the mounting block.

[0013] As a preferred embodiment, the bottom end of the screw rod is connected to the top end bearing of the filling station.

[0014] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0015] The filling machine of the lyophilized powder of sodium ceftiofur for injection benefits from the design of the protective plate, roller and limit assembly. The design of the protective plate and roller can protect the lyophilized powder of sodium ceftiofur for injection canned bottles when loading and unloading them, preventing them from falling from the conveyor belt and contaminating the filling bottles. The roller and the filling bottles adopt rolling friction to reduce the wear of the filling bottles. Secondly, the design of the limit assembly can limit the filling bottles when they are conveyed to the gap of the conveying tray, avoiding the wear of the filling bottles caused by the friction between the filling bottles and the outer wall of the conveying tray.

[0016] By providing a motor, a screw rod and a mounting block, when the filling bottle follows the conveying plate to move to the bottom of the filling tank, the motor drives the mounting block to move downward through the screw rod, and the filling rod at the bottom of the filling tank is inserted into the filling bottle, so that the lyophilized powder of ceftiofur sodium for injection can be prevented from scattering to the outside of the filling bottle during powder filling, thereby ensuring the accuracy of the powder amount in the filling bottle and avoiding the waste of the lyophilized powder of ceftiofur sodium for injection.

The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0039] How it works

[0040] The lyophilized powder of sodium ceftiofur for injection is loaded into the filling tank 5, and the conveyor belts 602 in the loading assembly 6 and the unloading assembly 7 are started respectively. The conveyor belt 602 in the loading assembly 6 drives the lyophilized powder of sodium ceftiofur for injection to be transported to the bottles until they are in contact with the limiting assembly 8. The control system controls the conveyor disc 2 to rotate. When the placement slot 201 on the conveyor disc 2 rotates to be on the same horizontal plane as the conveyor belt 602, the control system controls the conveyor disc 2 to stop rotating and open the limiting assembly 8, so that the conveyor belt 602 drives the lyophilized powder of sodium ceftiofur for injection to be transported to the placement slot 201. At this time, the control system controls the conveyor disc 2 to rotate and close the limiting assembly 8. Similarly, the lyophilized powder of sodium ceftiofur for injection is transported to the placement slot 201 one by one. Secondly, the lyophilized powder bottles are When following the conveying disk 2 to transport to the bottom of the filling tank 5, the control system controls the motor 401 to work when the rotating disk 2 stops rotating. The motor 401 drives the mounting block 403 to move downward through the screw rod 402, and the filling rod at the bottom of the filling tank 5 is inserted into the freeze-dried powder bottle and filled with powder. This can prevent the freeze-dried powder of ceftiofur sodium for injection from scattering to the outside of the filling bottle, thereby ensuring the accuracy of the filling powder amount and avoiding the waste of freeze-dried powder of ceftiofur sodium for injection. After the powder filling is completed, the filling tank 5 is reset, and the rotating disk 2 is controlled to rotate by the control system. When the freeze-dried powder bottle is transported to the contact with the guide plate 9 following the conveying disk 2, it will move to the conveyor belt 602 of the unloading component 7 through the guide plate 9, and follow 602 to transport the unloading, and the connection operation is performed in this way.
