[0002] The core tube is mainly used in industrial production, transportation, storage and other links. It is a tubular structure used to fix, protect and transfer goods. It has certain strength and pressure resistance. According to the characteristics of the actual coiled material, the core tube needs to have different sizes and materials. When manufacturing the core tube, the diameter of the core tube needs to be measured because different applications require different sizes. For example, the core tube generally used for paper product transportation is usually longer than the core tube used for medical gauze, and different diameters directly affect the thickness and length of the coiled material that can be wound around a single core tube. Therefore, a special core tube detection device is needed to measure the diameter of the core tube. However, the existing core tube diameter detection device generally has the following technical problems:

A dial 2 is fixedly connected to one side of the mounting plate 6, and the dial 2 is located below the placement groove 7. A pointer 5 is arranged on one side of the dial 2, and the pointer 5 is close to the upper surface of the dial 2. A front clamp unit 10 and a rear clamp unit 11 for positioning the core tube from both ends are respectively arranged on both sides of the mounting plate 6, and a mounting plate fixing mechanism for fixing the mounting plate 6 is arranged on the upper side of the base 1.

[0025] Please combine Figure 2 As shown, the clamping direction of the front clamp unit 10 on the winding core tube and the clamping direction of the rear clamp unit 11 on the winding core tube are perpendicular to each other, and the servo motor 12 of the front clamp unit 10 is in Figure 1 The servo motor 12 of the clamp unit 11 is on the right side. Figure 1 The upper sides of the winding core tubes are perpendicular to each other, so the winding core tube is clamped more stably.

[0026] Please combine Figure 3 As shown, the front clamp unit 10 and the rear clamp unit 11 both include a first clamp plate 8 and a second clamp plate 22, which are symmetrically distributed, and the first clamp plate 8 and the second clamp plate 22 are paired, and dovetail grooves 13 are provided on both sides of the first clamp plate 8 and the second clamp plate 22, and dovetail fixing blocks 15 are slidably connected to the inner sides of the two dovetail grooves 13, respectively, and the two dovetail fixing blocks 15 are fixedly connected to one side of the mounting plate 6 at the same time, and a clamp plate driving mechanism is provided on one side of the first clamp plate 8 and the second clamp plate 22 to move the first clamp plate 8 and the second clamp plate 22 closer to or away from each other.

[0027] It should be noted that a clamping nozzle of a certain width can be provided at the interface between the first clamping plate 8 and the second clamping plate 22 according to the actual diameter of the winding core tube, so as to facilitate the measurement of the winding core tube.

[0028] Please combine Figure 3 As shown, the card plate driving mechanism includes a No. 1 limit groove 14 respectively opened on both sides of the No. 1 card plate 8, a No. 1 limit block 16 is fixedly connected on both sides of the No. 2 card plate 22, and the No. 1 limit block 16 located on the same side is slidably connected to the No. 1 limit groove 14, and a No. 2 limit groove 20 is opened on both sides of the No. 2 card plate 22, and a No. 2 limit block 17 is fixedly connected on both sides of the No. 1 card plate 8, and the No. 2 limit block 17 located on the same side is slidably connected to the No. 2 limit groove 20, and one side of the No. 2 limit block 17 and the No. 1 limit block 16 is provided with a bidirectional toothed plate mechanism that allows the No. 1 card plate 8 and the No. 2 card plate 22 to be equidistantly close to or away from each other.

[0029] It should be noted that the height of the No. 2 limit block 17 and the No. 1 limit block 16 protrudes from the sides of the No. 1 clamping plate 8 and the No. 2 clamping plate 22, so that sufficient space can be set for the No. 2 gear plate 19 and the No. 1 gear plate 18 to avoid interference between the gear 21 and the No. 1 clamping plate 8 and the No. 2 clamping plate 22.

[0030] Please combine Figure 3As shown, the bidirectional gear plate mechanism includes a No. 2 gear plate 19 fixedly connected to one side of the two No. 2 limit blocks 17, and a No. 1 gear plate 18 fixedly connected to one side of the two No. 1 limit blocks 16, respectively. The No. 1 gear plate 18 and the No. 2 gear plate 19 located on one side are meshed with a gear 21, and the two gears 21 are rotatably connected to the mounting plate 6.

Since the No. 2 limit block 17 is fixedly connected to the No. 1 clamping plate 8, the No. 1 clamping plate 8 indirectly pushes the No. 2 tooth plate 19 to move to one side. Due to the meshing action of the gear 21, the No. 1 tooth plate 18 moves in the opposite direction at this time. Since one end of the No. 1 tooth plate 18 is fixedly connected to the No. 2 clamping plate 22, the No. 2 clamping plate 22 and the No. 1 clamping plate 8 are equidistantly approaching the placement slot 7, and finally the outer wall of the core tube is clamped. The movement of the No. 2 tooth plate 19 drives the pointer 5 to move and indicates the size on the dial 2.

[0035] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
