Technical Field

[0001] The utility model relates to the technical field of capsule production, in particular to a capsule filling machine with a waste removing mechanism. Background Art

[0002] Chinese Patent Publication No. "CN219127451U" discloses a capsule filling machine, which includes a frame and a conveyor belt. The conveyor belt is arranged below the frame. A filling component, a sleeving component and a storage box are arranged on the frame. The filling component and the sleeving component are both arranged on the frame, and the storage box is arranged on one side of the conveyor belt far away from the filling component.

[0003] Capsules are a dosage form widely used clinically. They can cover up the bad smell of drugs or improve the drug stability, solving the problem that some drugs are difficult to take orally and have a poor taste for users. When producing capsules, a filling machine is used to fill powder or granular drugs into the capsules. In the existing capsule filling machines during use, the drugs are first filled into the capsule body, and then the capsule cap is sleeved on the capsule body. However, when the capsule cap is sleeved on the capsule body, it may not be properly sleeved due to manufacturing defects, such as size problems or the openings of the capsule cap or the capsule body being elliptical, etc. If the capsule caps and capsule bodies that cannot be properly sleeved are not removed in time, they will be discharged together with the properly sleeved capsules. Therefore, a capsule filling machine with a waste removing mechanism is proposed. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] The capsule filling machine with a rejection mechanism provides two technical solutions:

[0024] Such as Figures 1-4The first embodiment is shown: It includes a workbench 1, a filling component 2, a conveying mechanism 3 and a sleeving mechanism 4. A plurality of capsule placement seats 8 are fixedly connected at equal distances on the surface of the conveyor belt of the conveying mechanism 3. A waste removal mechanism 6 is arranged on the front of the workbench 1. Specifically, the waste removal mechanism 6 is located on the left side of the sleeving mechanism 4 and is aligned directly below the position of the capsule placement seat 8 after the sleeving process. A detection component 7 is also arranged on the front of the workbench 1. Specifically, the detection component 7 is located on the left side of the sleeving mechanism 4 and is aligned directly above the position of the capsule placement seat 8 after the sleeving process;

[0025] The waste removal mechanism 6 includes a rotating rod 61. The rotating rod 61 is rotatably connected to the back of the workbench 1. The other end of the rotating rod 61 is fixedly connected with a disc 62. A chute 63 is opened inside the workbench 1. A support plate 64 is slidably connected between the left and right inner walls of the chute 63. The back of the support plate 64 is rotatably connected with a connecting rod 65. The other end of the connecting rod 65 is rotatably connected with the back of the disc 62. A top rod 611 that can be telescoped up and down is arranged inside the chute 63, and the telescoping process of the top rod 611 is determined by the detection result of the detection component 7. The back of the workbench 1 is fixedly connected with a driving motor 66 through a fixing plate. The output end of the driving motor 66 is fixedly connected with a first pulley 67. The surface of the rotating rod 61 is fixedly connected with a second pulley 68. The first pulley 67 and the second pulley 68 are connected by a belt drive. The bottom of the chute 63 is fixedly connected with an adjustment motor 69. The output end of the adjustment motor 69 is fixedly connected with a lead screw 610. The lead screw 610 is slidably connected with the top of the chute 63. The top rod 611 is also threadedly connected with the surface of the lead screw 610.

[0026] When the capsule filling machine is working, the waste removal mechanism 6 removes the capsules in which the capsule body and the capsule cap are not correctly sleeved, and the waste removal mechanism 6 can cooperate with the automated process of the overall equipment without affecting the normal use of the device, improving the practicality of the device during use.

[0027] As Figure 1 And 3 -5 shows the second embodiment. The main difference from the first embodiment is that the detection component 7 includes a sliding plate 71. The sliding plate 71 is slidably connected to the front of the workbench 1. One end of the sliding plate 71 that penetrates the workbench 1 and extends to the back of the workbench 1 is fixedly connected with a push block 72. A return spring 73 is fixedly connected between the back of the workbench 1 and the side opposite to the push block 72, and the return spring 73 is sleeved outside the sliding plate 71. A top block 74 is fixedly connected to the front of the disc 62. The top block 74 cooperates with the push block 72. A plurality of infrared sensors 75 are embedded at the bottom of the sliding plate 71.

[0028] After the capsule filling machine fits the capsule body and the capsule cap, the detection component 7 detects whether the capsule body and the capsule cap are correctly fitted, and controls the extending length of the ejector rod 611, so that the capsules that are not correctly fitted can be accurately removed.

[0029] During use, after the fitting mechanism 4 fits the capsule cap and the capsule body, the conveying mechanism 3 operates and drives the capsule body placing seat 8 to move between the waste removing mechanism 6 and the detection component 7. During the movement of the capsule body placing seat 8, the driving motor 66 is started and drives the first pulley 67 to rotate. The first pulley 67 rotates and drives the second pulley 68 to rotate through the belt. The second pulley 68 rotates and drives the disc 62 to rotate through the rotating rod 61. The disc 62 rotates and drives the support plate 64 to reciprocate up and down under the drive of the connecting rod 65. During the process that the capsule body placing seat 8 moves leftward away from under the fitting mechanism 4, the support plate 64 is in the upward moving state. At the same time, under the drive of the disc 62, the top block 74 rotates and starts to contact the push block 72, and pushes the slide plate 71 forward. After the slide plate 71 is pushed out, the infrared sensor 75 detects the height of the capsules in the capsule body placing seat 8. For the capsules with a height lower than the standard data, the adjustment motor 69 at the corresponding position is started. The adjustment motor 69 rotates and drives the lead screw 610 to rotate. The rotation of the lead screw 610 makes the ejector rod 611 move upward. Then when the support plate 64 moves to the uppermost position, the ejector rod 611 enters the capsule body groove 81 through the through hole and removes the capsules that are not correctly fitted, and they fall into the collection tank 5.
