Description

Technical Field

[0001] The utility model relates to the technical field of tablet detection, in particular to a tablet detection device. Background Art

[0002] Tablet inspection is a necessary process in tablet packaging, because when tablets are loaded into aluminum-plastic plates, there are defects such as partial tablet loss, which will affect the quality of tablets. At present, tablets are often inspected by imaging during packaging, and defective tablets can be picked out through inspection. However, for some tablets, due to microcracks on them, the powder enters the cracks when the tablets are put in, making it difficult to find the microcracks through imaging, and tablets with microcracks are prone to cracking during later packaging.

[0012] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0015] like Figure 1~Figure 2 As shown, a tablet detection device comprises a back plate 1, a detection cylinder 3 is mounted on the back plate 1, a pressure sensor 31 is arranged at the lower end of the detection cylinder 3, a lower pressure rod 32 is arranged at the lower end of the pressure sensor 31, the lower pressure rod 32 is a spline shaft structure, and a guide sleeve 33 is sleeved on the lower pressure rod 32, and the guide sleeve 33 is mounted on the back plate 1. An upper cylinder 4 is mounted at the lower end of the lower pressure rod 32, a middle ring 40 is mounted at the lower end of the upper cylinder 4, an inner ring of the middle ring 40 is provided with an annular groove 41, a movable ring 50 is arranged in the annular groove 41, gratings are arranged on the upper and lower walls of the annular groove 41, and a plurality of photoelectric sensors are embedded in the movable ring 50. A connecting head 49 is provided on the movable ring 50, and an assembly groove with a U-shaped cross-section is provided inside the connecting head 49, an upper sphere 48 is provided in the assembly groove, a middle rod 45 is provided on the upper sphere 48, a lower cylinder 42 is provided at the lower end of the middle ring 40, a ball seat 43 is provided at the lower end of the lower cylinder 42, a lower ball 44 is provided at the lower end of the middle rod 45, the lower ball 44 is provided in the ball seat 43, a lower rod 46 is provided on the lower ball 44, a deflection plate 47 is provided at the lower end of the lower rod 46, and a groove is formed at the lower end of the deflection plate 47.

[0016] A mounting plate 11 is provided at the lower end of the back plate 1 , a limit plate 2 is mounted on the mounting plate 11 , and a conveying groove 20 is formed at the upper end of the limit plate 2 .

[0017] A conical column 51 is provided at the upper end of the connector 49 . The upper end of the conical column 51 is a small end. A positioning cylinder 53 is installed in the upper cylinder 4 . A positioning sleeve 52 is provided at the lower end of the positioning cylinder 53 . The positioning sleeve 52 is sleeved on the conical column 51 .

[0018] When the present embodiment is in operation, the tablets are passed through the conveying trough 20 one by one via the conveyor belt.

[0019] When one of the tablets passes directly under the deflection disk 47, the detection cylinder 3 is started, and the deflection disk 47 moves downward under the drive of the detection cylinder 3. When the deflection disk 47 moves downward, it will act on the tablet. If there are microcracks on the tablet, the tablet will split under the action of squeezing. When the tablet splits, the balance of the reaction force on the deflection disk 47 will be destroyed, and the deflection disk 47 will tilt downward to one side. The inclination of the deflection disk 47 will act on the connecting head 49 through the upper sphere 48, thereby causing the movable ring 50 to move in the ring groove 41. When moving, the photoelectric sensor will obtain the movement data of the movable ring 50, thereby obtaining whether there are microcracks or splits in the tablet.

[0020] When the tablet hardness test is being performed, the positioning cylinder 53 is started to allow the positioning sleeve 52 to position the conical column 51. Through the limitation of the positioning sleeve 52, the axial direction of the middle rod 45 and the axial direction of the connecting head 49 will coincide with each other. Then, driven by the detection cylinder 3, the deflection disk 47 will punch the tablet, and the hardness of the tablet will be obtained through the pressure sensor 31.
