[0019] See also Figure 1-2 As shown, the utility model is a rapid measuring device for the inner diameter of a plastic core of a tobacco auxiliary material, comprising a connecting rod 1, with standard round blocks 3 for measuring the inner diameter of the plastic core provided at both ends of the connecting rod 1, the standard round block 3 and the connecting rod 1 being detachably connected via a hexagon socket bolt 4, a telescopic measuring device for measuring different inner diameters is provided on one side of the connecting rod 1 of the standard round block 3, the telescopic measuring device comprising a plurality of arc-shaped measuring blocks 5 and a telescopic mechanism 2 for driving the plurality of arc-shaped measuring blocks 5 to expand or contract, the telescopic mechanism 2 being mounted on the standard round block 3, the arc-shaped measuring block 5 being connected to the telescopic end of the telescopic mechanism 2, when measuring the plastic core of the standard part, holding one end of the device, and using the standard round block 3 as the measuring end to move vertically downward along the wall of the plastic core until the standard round block 3 can pass through the plastic core completely without a gap or with a relatively small gap, and the plastic core is deemed to have passed the inspection; If there is a large gap between the plastic core and the standard round block, the plastic core is considered unqualified. When measuring the plastic core of non-standard parts, since the size of the plastic core of non-standard parts will be larger than that of standard parts, the instrument is first placed in the plastic core, and the rotating handle 10 is turned to drive the rotating gear 6 to rotate, and the rotating gear 6 drives the gear plate 21 to rotate. During the rotation of the gear plate 21, the connecting column 24 is driven by the arc groove 22, thereby driving the telescopic rod 23 to extend on the standard round block 3, thereby extending the arc measuring block 5. When the arc measuring block 5 contacts the inner wall of the plastic core, observe whether the value on the scale 8 is within the set standard range value, so as to quickly determine whether the plastic core of the non-standard part is qualified. This device can quickly reflect the quality status of the inner diameter of the plastic core of standard parts and non-standard parts, and achieve the purpose of fast and accurate inspection.

[0020] Specifically, the telescopic mechanism 2 includes a gear plate 21 and a plurality of telescopic rods 23. The gear plate 21 is provided with a plurality of arc grooves 22 arranged in a ring shape. The gear plate 21 is rotatably installed at the center of the standard round block 3. The plurality of telescopic rods 23 are arranged in a ring shape on the standard round block 3. The telescopic rods 23 are slidably plugged into the standard round block 3. A connecting column 24 is provided at one end of the telescopic rod 23. The connecting column 24 is plugged into the arc groove 22. The other end of the telescopic rod 23 is connected to the arc measuring block 5. By rotating the rotating handle 10, the rotating gear 6 is driven to rotate, and the rotating gear 6 drives the gear plate 21 to rotate. During the rotation of the gear plate 21, the connecting column 24 is driven under the action of the arc groove 22, thereby driving the telescopic rod 23 to extend on the standard round block 3, thereby extending the arc measuring block 5. When the arc measuring block 5 contacts the inner wall of the plastic core, observe whether the value on the scale 8 is within the set standard range value, which can meet the inspection requirements of different inner diameters of the plastic core and increase practicality.

[0021] Preferably, a rotating gear 6 is rotatably provided on the standard round block 3, and the rotating gear 6 is meshed and connected with the gear plate 21. The rotating gear 6 rotates, and the rotating gear 6 drives the gear plate 21 to rotate. The rotating gear 6 is smaller than the gear plate 21, and the small gear drives the large gear to rotate more labor-saving, which is convenient for operators to use.

[0022] Furthermore, a synchronization rod 9 is provided between the rotating gears 6 on the standard round blocks 3 at the upper and lower ends, and the two ends of the synchronization rod 9 are respectively connected to the rotating gears 6 at the upper and lower ends, so that the arc-shaped measuring blocks 5 at the upper and lower ends are extended at the same time. During measurement, whether the inner diameters of the upper and lower ends of the plastic core are uniform can be measured, thereby increasing the accuracy of the measurement. The synchronization rod 9 is rotationally connected to the standard round block 3.

[0023] Furthermore, a rotating handle 10 for rotating the rotating gear 6 is provided on one side thereof, so that an operator can drive the rotating gear 6 conveniently.

[0024] Furthermore, a mounting hole 12 is opened in the middle of the standard round block 3, and a filling block 11 is arranged in the mounting hole 12. The gear plate 21 is rotatably mounted on the filling block 11. The filling block 11 and the mounting hole 12 have an interference fit, which is convenient for installing the hexagon socket bolt 4 and is used to provide a position to support the installation of the gear plate 21.

[0025] Furthermore, a scale 8 is provided on one of the telescopic rods 23 , and an observation slot 7 is provided on the standard round block 3 above each telescopic rod 23 , so that the observation slot 7 is convenient for observing the scale value of the scale 8 .

[0026] Furthermore, the outer diameter formed when the multiple arc-shaped measuring blocks 5 are contracted to the minimum distance is consistent with the outer diameter of the standard circular block 3. When measuring the plastic core of a standard part, the entire device can be placed in the plastic core for measurement so that the device can simultaneously measure standard parts and non-standard parts.

[0027] When using the rapid measuring device for the inner diameter of the plastic core of tobacco auxiliary materials of the present embodiment, when measuring the plastic core of a standard part, hold one end of the device, use the standard round block 3 as the measuring end and move it vertically downward along the wall of the plastic core until the standard round block 3 can pass through the plastic core completely without a gap or a small gap, the plastic core is considered to be qualified; if there is a large gap between the plastic core and the standard round block, the plastic core is considered to be unqualified. When measuring the plastic core of a non-standard part, since the size of the plastic core of the non-standard part is larger than that of the standard part, put the device into the plastic core first, and drive the rotating handle 10 by turning it. The rotating gear 6 rotates, and the rotating gear 6 drives the gear plate 21 to rotate. During the rotation of the gear plate 21, the arc groove 22 drives the connecting column 24, thereby driving the telescopic rod 23 to extend on the standard round block 3, thereby extending the arc measuring block 5. When the arc measuring block 5 contacts the inner wall of the plastic core, observe whether the value on the scale 8 is within the set standard range value, so as to quickly judge whether the plastic core of the non-standard part is qualified. This device can quickly reflect the quality status of the inner diameter of the plastic core of the standard part and the non-standard part, and achieve the purpose of rapid and accurate inspection.
