Description

Technical Field

[0001] The utility model relates to the technical field of medicine and food packaging machinery and equipment, in particular to a feeding mechanism of a detection device. Background Art

[0002] The vacuum leak detector for medicine bottles such as vials generally uses a bottle feeding auger connected to a bottle feeding dial, which is then connected to a detection turntable, and the pitches of the bottle feeding auger, bottle feeding dial and detection turntable are all equal. However, for slender containers such as cartridge bottles, a too large pitch of the bottle feeding auger will cause the cartridge bottle to tilt, making the pitch of the bottle feeding auger smaller than the pitch of the detection turntable, and the bottle feeding dial cannot increase the pitch. Therefore, a detection device feeding mechanism with a variable pitch function is urgently needed for feeding slender containers such as cartridge bottles. Utility Model Content

DETAILED DESCRIPTION

[0025] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] The embodiment of the utility model is a feeding mechanism of a detection device, such as Figure 1 and Figure 2 As shown, it includes a feeding mechanism 2 and a detection turntable 4, a variable-distance conveying mechanism 3 is arranged between the feeding mechanism 2 and the detection turntable 4, the variable-distance conveying mechanism 3 includes at least one section of a straight conveying section 31 and a curved conveying section 32, and a plurality of feeding members 33, the straight conveying section 31 and the curved conveying section 32 are connected end to end, the feeding members 33 circulate and convey on the straight conveying section 31 and the curved conveying section 32, and the feeding mechanism 2 and the detection turntable 4 are respectively connected to the straight conveying section 31 and the curved conveying section 32.

[0027] Furthermore, the straight conveying section 31 and the arc-shaped conveying section 32 are surrounded by the synchronous wheel 35, and the synchronous wheel 35 is connected to the driving mechanism, so that the straight conveying section 31 and the arc-shaped conveying section 32 have a structure similar to a synchronous belt.

[0028] Further, such as Figure 3 As shown, a feeding trough 34 matching the outer diameter of the material is provided at the end of the feeding member 33, and a fence 6 located outside the variable-distance conveying mechanism 3 is provided between the feeding mechanism 2 and the detection turntable 4. In this embodiment, the feeding trough 34 cooperates with the fence 6 to realize the conveyance of the material on the variable-distance conveying mechanism 3. It is also possible to convey the material only through the feeding trough 34, including but not limited to the feeding trough 34 driving the material through suction to realize the conveyance.

[0029] In this embodiment, the feeding members 33 are equidistantly arranged on the straight conveying section 31 and the arc-shaped conveying section 32, and due to the arc-shaped characteristics, the end spacing of the feeding members 33 on the arc-shaped conveying section 32 is greater than the end spacing of the feeding members 33 on the straight conveying section 31. In addition, the feeding members 33 can also be unequally arranged on the straight conveying section 31 and the arc-shaped conveying section 32 as required.

[0030] As can be seen from the above, when the straight conveying section 31 is connected to the arc conveying section 32, that is, when the feeding mechanism 2 is connected to the straight conveying section 31 and the detection turntable 4 is connected to the arc conveying section 32, the pitch becomes larger; when the arc conveying section 32 is connected to the straight conveying section 31, that is, when the feeding mechanism 2 is connected to the arc conveying section 32 and the detection turntable 4 is connected to the straight conveying section 31, the pitch becomes smaller. Therefore, by setting different orders for materials to enter the straight conveying section 31 and the arc conveying section 32, the pitch can be increased or decreased, and the applicability is wide.

[0031] In this embodiment, for feeding of slender cartridge bottles, the feeding mechanism 2 intersects with the straight conveying section 31, and the detection turntable 4 intersects with the arc conveying section 32, and the pitch becomes larger. To facilitate smooth handover, the end spacing of the feeding members 33 on the arc conveying section 32 is the same as the pitch of the detection turntable 4; the end spacing of the feeding members 33 on the straight conveying section 31 is the same as the end pitch of the feeding mechanism 2.

[0032] In this embodiment, Figure 1 As shown, the feeding mechanism 2 includes a feeding screw, the feeding end of the feeding mechanism 2 is connected to the feeding mesh belt 1, and the detection turntable 4 is also connected to the inlet of the dividing mechanism 5, and the outlet of the dividing mechanism 5 outputs materials through the first discharging mechanism 7 and the second discharging mechanism 8.

[0033] Therefore, in this embodiment, the material cartridge bottle conveys the material to the feeding end of the feeding mechanism 2 through the feeding mesh belt 1, and the feeding mechanism 2 conveys the disordered material in an orderly manner; the thread pitch on the feeding screw gradually increases from the feeding end to the end, but in order to prevent the cartridge bottle from tilting, the pitch of the feeding screw is still smaller than the pitch of the detection turntable 4 after being appropriately increased, and the variable pitch conveying mechanism 3 is required to further increase the pitch; the end pitch of the feeding screw is the same as the pitch of the straight conveying section 31, the feeding mechanism 2 delivers the material to the straight conveying section 31, and then conveys it to the arc conveying section 32, increases the pitch to be the same as the pitch of the detection turntable 4, and delivers the material to the detection turntable 4; the material is detected in the detection turntable 4 to separate qualified products and unqualified products, and is separated by the separating mechanism 5, and the material is output from the first discharging mechanism 7 and the second discharging mechanism 8 respectively.

[0034] In summary, the feeding mechanism of the above-mentioned detection device has the following beneficial effects:

[0035] (1) The utility model realizes the adjustment of increasing or decreasing the pitch of the material according to the characteristic that the end pitch of the material conveying member of the variable-pitch conveying mechanism becomes smaller in the straight conveying section and becomes larger in the arc conveying section;

[0036] (2) Compared with other pitch-changing mechanisms, the utility model is simpler and more compact in structure, has lower cost, and can be used in various scenarios where the pitch is increased or decreased, and has good promotion significance.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it; although the implementation mode of the utility model is described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the utility model, and such modifications and variations are all within the scope defined by the attached claims.
