Description

Technical Field

[0001] The present invention relates to a cleaning and collecting device for capsule drugs in a laboratory, which is used for the content uniformity test of capsules. Background Art

[0002] Content uniformity: Take 20 capsules, accurately weigh each capsule respectively, pour out the contents (without losing the capsule shells), wipe the hard capsule shells clean with a small brush or other suitable tools, then accurately weigh the capsule shells respectively, and calculate the content weight and average content weight of each capsule. And the poured-out contents are collected together for subsequent detection; when collecting the contents, try not to spill or contaminate them, so that the sampling is representative.

[0003] In actual work, it is necessary to manually weigh the content uniformity of 20 capsules, weigh the total weight of each capsule shell, clean the inner wall of the capsule shell, then weigh the capsule shell weight, and subtract the total weight of the capsule shell from the total weight to obtain the content weight of each capsule. The operation is cumbersome, time-consuming and laborious. Moreover, the capsule dust will float in the air, which will not only cause a decrease in the capsule content weight, but also pollute the environment, and at the same time pose a threat to the health of the inspection personnel.

[0009] A further improvement of the technical solution of the present invention lies in that: the outer end of the elastic capsule clamping piece turns outward towards the inner wall of the capsule insertion groove, and elastic protrusions or elastic patterns are provided on the concave surface of the elastic capsule clamping piece.

[0010] A further improvement of the technical solution of the present invention lies in that: ultrasonic vibrators are respectively provided on the grasping surfaces of the first grasping disc and the second grasping disc.

[0011] A further improvement of the technical solution of the present invention lies in that: rotating shafts are respectively and fixedly provided at the tops of the first grasping disc and the second grasping disc. Both ends of the rotating shaft are respectively hinged to the supporting seats on the inner wall of the cleaning device body. A gear driven to rotate by a rotating device is also fixedly provided on the rotating shaft.

[0012] A further improvement of the technical solution of the present invention lies in that: the rotating device includes a fixed block fixedly provided on the supporting seat and a first telescopic cylinder fixedly provided on the fixed block; a sliding block is fixedly provided at the end of the telescopic rod of the first telescopic cylinder. A sliding rod passing through the fixed block and moving along the fixed block is fixedly provided on the sliding block. The other end of the sliding rod is fixedly provided with a gear sliding block that moves along with the sliding rod, and teeth matching with the gear are provided on the gear sliding block; the teeth of the gear sliding block driving the first grasping disc to rotate are provided at the top, and the teeth of the gear sliding block driving the second grasping disc to rotate are provided at the bottom.

[0013] A further improvement of the technical solution of the present invention lies in that: two sets of rotating devices for driving the first grasping disc or the second grasping disc to rotate are respectively symmetrically provided, and the first telescopic cylinders are synchronously linked.

[0014] A further improvement of the technical solution of the present invention lies in that: bearings are respectively provided at both ends of the rotating shaft, a bearing seat is provided at the top of the supporting seat, and the bearing is hinged inside the bearing seat.

[0018] The present invention can automatically separate multiple capsule shells, pour out the contents by the flipping of the first gripping disc and the second gripping disc, and automatically collect them in a medicine collection box for subsequent measurement of the filling quantity. Moreover, the separation is horizontal separation, and the contents are directly poured out by flipping 90°, so that the contents will not be spilled onto the device to affect subsequent detection (compared with the capsule shells separated vertically, one of the capsule shells needs to be flipped 180°, and the contents are very likely to be spilled onto the device). And the operation of pouring out the contents is carried out inside the closed cleaning device body, which can reduce the harm to the inspection personnel caused by dust volatilization and protect the environment at the same time.

[0019] The present invention uses a telescopic elastic capsule clip to clamp the capsule. Compared with vacuum suction of the capsule shell (vacuum suction is point suction, and if the vacuum degree is not properly operated, the capsule shell is likely to be sucked and broken or not firmly sucked), the contact changes from point contact to surface contact, with a larger contact area, making it easier to protect the capsule shell from cracking. And the elastic protrusions or elastic patterns provided on the elastic capsule clip can increase the frictional resistance, making the clamping of the capsule shell more firm.

[0020] The present invention is also respectively provided with ultrasonic vibrators on the first gripping disc and the second gripping disc, which can prevent the contents from adhering to the inner wall of the capsule shell, which is superior to brushing off the contents adhering to the inner wall of the capsule shell with a brush (because part of the contents will adhere to the brush), affecting the subsequent detection of the contents.

[0021] The present invention is respectively symmetrically provided with two sets of rotating devices for driving each gripping disc to rotate, and the first telescopic cylinder is synchronously linked, making the flipping of the gripping disc smoother and having a longer service life.

[0022] The setting of the second telescopic cylinder and the sliding groove in the present invention can provide an initial force for the first gripping disc and the second gripping disc to start flipping to both sides, protecting the rotating device at the top of the gripping disc.
