Description

Technical Field

[0001] The present application relates to the technical field of detection equipment, and more specifically, to a debris detection and removal device. Background Art

[0002] Currently, most oral medicines produced are in the form of tablets. The quality of tablets directly affects the quality of the entire medical product. Therefore, the production of tablets has strict requirements. Defective tablets that are broken, damaged, or have impurities on the surface during the production process need to be selected. There are hundreds of varieties of tablets, and their appearance, shape, size, etc. are very different. If manual selection is relied upon, not only will the labor cost be high, but it will also be difficult to fully grasp the appearance, shape and size of the tablets, which can easily lead to false detection and missed detection, affecting the qualified rate of the tablets.

[0003] In the prior art, the produced tablets are usually inspected by a tablet inspection machine and then the residual tablets are removed. For example, a vacuum suction device with Chinese patent number CN220115662U adopts a new structural design, so that during use, the device uses a vacuum negative pressure tube and a discharge negative pressure tube to form a negative pressure inside the conveying box, thereby sucking the unqualified tablets detected into the temporary storage box and finally discharging them from the discharge negative pressure tube to achieve the purpose of automatic removal. In this process, a protective baffle is used to prevent the tablets from being blocked at the first through hole position when being sucked in. At the same time, the temporary storage box can be disassembled to facilitate manual removal of the tablets that cannot be discharged from the inside.

[0004] When the above technology uses a straw to suck up broken tablets, the straw is also in a negative pressure environment. At the same time, the inside of the straw will be impacted by the broken tablets. The straw is easily damaged by vibration. Simple bolt fixing cannot ensure the stability and safety of the straw during the absorption of damaged tablets. In view of this, we propose a fragment detection and rejection device.

DETAILED DESCRIPTION

[0026] like Figure 1 and Figure 2 As shown, a device for detecting and rejecting broken tablets is placed in front of the counting machine 3 to reject broken, broken, or defective tablets. The produced tablets are transferred to the device, which is equipped with a multi-stage vibration plate, such as Figure 6As shown, a plurality of grooves are provided on the vibration plate, and the grooves are parallel to the straw 21. A straw 21 is provided above each groove. The vibration plate vibrates to convey the tablets to be inspected, and also performs separation processing, so that the tablets are dispersed in each groove. The tablets separated and conveyed by the vibration plate pass through the particle detection mechanism 1 and move along the material running direction. The detection principle is similar to the tablet defect identification device in Chinese Patent No. CN102798727B, and a scanning camera is used for imaging to perform 360-degree inspection. ° Appearance inspection, fast and accurate monitoring. After the camera of the broken tablet detection mechanism 1 detects the broken tablet, the broken tablet rejection mechanism 2 performs a tablet rejection operation. The rejection operation principle is as described in the structure of Chinese Patent No. CN220115662U. During the use of the device, the negative pressure device 23 is activated to form a negative pressure inside the broken tablet rejection mechanism 2 using the vacuum negative pressure tube 24. When the broken tablet moves to the suction pipe 21 fixed at the bottom end of the broken tablet rejection mechanism 2, the partition structure 25 above the suction pipe 21 is activated to open the broken tablet rejection mechanism 2 in a negative pressure state, so that a negative pressure is formed inside the suction pipe 21. Unqualified tablets can be sucked into the suction pipe 21, and qualified tablets are transmitted to the counting machine 3 behind the broken tablet rejection mechanism 2.

[0027] like Figure 6 , Figure 4 and Figure 3 As shown, a fixing block 26 is fixedly provided at the bottom end of the vacuum negative pressure tube 24, and a partition structure 25 is provided inside the fixing block 26. The bottom end of the fixing block 26 is fixed to the outside of the straw 21 through a limiting structure. The limiting structure includes a limiting frame 271, a connecting rod 272, a rotating shaft 273 and a hinge 274. The limiting frame 271 is two symmetrically arranged semicircular rings. A card groove is opened on the inner side of the semicircular ring. The size of the card groove is the same as the size of the top end of the straw 21. The semicircular ring can engage with the outside of the top end of the straw 21. A connecting rod 272 is fixedly connected to the outside of one limiting frame 271. The connecting rod 272 consists of a rectangular plate and a positioning block. The positioning block is fixedly connected to one side of the top end of the rectangular plate. The other end of the other limiting frame 271 is fixedly connected to a hinge 274. The other end of the hinge 274 is fixedly connected to the connecting rod 272. The middle part of the side of the connecting rod 272 away from the positioning block is fixedly connected to the hinge 274.

[0028] like Figure 5 and Figure 4As shown, a limiting groove 261 is provided above the fixed block 26, and the limiting groove 261 is set as a circular groove, and a square groove cooperating with the baffle 251 is provided inside the circular groove, and a sliding groove 262 is fixedly provided on the side of the fixed block 26 at the bottom of the limiting groove 261, and the inner side of the sliding groove 262 is slidably connected with the positioning block of the connecting rod 272, and the baffle 251 is completely engaged with the inner side of the square groove, and a rectangular labyrinth seal is formed between the square groove and the circular groove and the baffle 251, so as to further seal the space of the broken particle removal mechanism 2 and avoid leakage in the negative pressure environment of the broken particle removal mechanism 2;

[0029] like Figure 4 and Figure 5 As shown, the partition structure 25 includes a baffle 251, an electric telescopic rod 252 and a movable stopper 253. The output end of the electric telescopic rod 252 is fixedly connected to the baffle 251. When the baffle 251 is in an extended state, the limit groove 261 of the fixed block 26 is closed. When the baffle 251 is in a fully retracted state, it is hidden inside the fixed block 26 and does not block the upper part of the straw 21 and the bottom end of the fixed block 26. A plurality of movable stoppers 253 are symmetrically arranged on the side of the baffle 251. The movable stopper 253 is composed of a knob spring, a round shaft and a fixed round block. The fixed round block is rotatably connected to the side of the baffle 251 through the round shaft, and the outer side of the round shaft is fixedly connected with a knob spring.

[0030] The partition structure 25 is started so that the inside of the straw 21 is in a negative pressure environment, the electric telescopic rod 252 contracts to drive the baffle 251 to move, and the movement of the baffle 251 drives multiple movable blocks 253 to move synchronously. The movable blocks 253 are embedded in the inner side of the slide groove 262 when the baffle 251 is extended to close the fixed block 26. The movement of the baffle 251 can drive the movable blocks 253 to move, and the movement of the movable blocks 253 can squeeze the positioning block on one side of the top of the connecting rod 272, so that the movable blocks 253 can drive the top of the connecting rod 272 to move, and the connecting rod 272 fixed on one side of the limiting frame 271 can drive the limiting frame 271 to move synchronously, and the top of the other connecting rod 272 is forced to move while connecting The rectangular plate of rod 272 can rotate around the rotating shaft 273, and the positioning blocks at the bottom end of connecting rod 272 and the top end of connecting rod 272 move to opposite positions. When baffle 251 moves to the hidden position, the two limit frames 271 both move to the position engaged with the outer side of straw 21, so as to further limit and fix the straw 21, thereby ensuring the stability of straw 21 when sucking up debris. At this time, the vacuum negative pressure tube 24 and straw 21 are in a linked negative pressure state, and the debris moved to the bottom end of the particle removal mechanism 2 can be sucked into the inside of straw 21, and the debris moves from straw 21 to the vacuum negative pressure tube 24 in the negative pressure environment, and the vacuum negative pressure tube 24 moves to the recovery chamber 22, so as to realize the removal operation of the debris.
