[0002] The detection bead detector is a traditional inspection device for checking the inner diameter of pipes during pipe production. The starting end of the pipe is located above the magnet. As shown in the picture, during the continuous production process of the pipe, it moves continuously from right to left. A detection bead needs to be placed inside the pipe as a device for checking the inner diameter of the pipe.

[0003] The traction machine pulls the pipe, and the pipe moves along the four guide wheels. When the pipe moves, the detection beads are adsorbed by the magnet and fixed above the magnet and below the detection probe. When the inner diameter of the pipe product becomes smaller, the detection beads will be taken away by the moving pipe. When the detection probe cannot recognize the detection beads, it will determine that the pipe size is unqualified and alarm.

DETAILED DESCRIPTION

[0027] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] Embodiment 1

[0030] Please refer to Figure 1 A front view of a steel ball detector is shown, wherein the steel ball detector comprises a feeder for conveying the finished pipe 1;

[0031] A pipe reel, used for reeling pipes 1;

[0032] A detection device, which is arranged between the feeder and the pipe reel, and is used to detect the pipe 1 delivered from the feeder;

[0033] The detection device includes a detection component, which includes a fixed column 18, a fixed plate 7 is fixedly connected to the side wall of the fixed column 18, a detection probe 9 is fixedly arranged on the top of the side wall of the fixed plate 7 away from the fixed column 18, and a magnet 8 is arranged at the bottom, and the detection probe 9 is located directly above the magnet 8, and the detection probe 9 has a detection end, and the detection end is aligned with the magnet 8;

[0034] The detection probe 9 is electrically connected to the external controller and the alarm;

[0035] The detection device also includes a detection bead 2, which is located inside the pipe 1 and attracted to the magnet 8. When the pipe 1 is detected, the detection bead 2 is located inside the pipe 1 and attracted to the magnet 8. During the continuous transmission of the pipe 1 to the pipe reel, due to the attraction of the magnet 8, the detection bead 2 moves relative to the pipe 1 and will not be carried away by the pipe 1. During the detection process, the detection end can always be aligned with the detection bead 2. When the inner diameter of the pipe 1 becomes smaller, the detection bead 2 will be stuck and carried away by the transmitted pipe 1. At this time, the detection end cannot detect the detection bead 2, so the alarm is triggered and the equipment is shut down by connecting to an external controller.

[0036] like Figure 3 As shown, the detection bead 2 includes a layered structure, which is made of PE material. The layered structure includes a first layer 3 and a second layer 4 wrapped inside and outside. A mesh layer 6 is arranged between the first layer 3 and the second layer 4. The inner and outer sides of the mesh layer 6 are respectively fixedly connected to the outer wall of the second layer 4 and the inner wall of the first layer 3, so as to enhance the structural strength of the detection bead 2. An iron powder core 5 is arranged in the second layer 4 for attracting the magnet 8. The iron powder core 5 is filled with iron powder, and the iron powder needs to account for 50%-70% of the volume of the detection bead 2.

[0037] The detection device also includes a guide wheel assembly 10, which includes an upper guide wheel group and a lower guide wheel group, and the upper guide wheel group and the lower guide wheel group are both movably arranged on the fixed plate 7;

[0038] Specifically, Figure 1 and Figure 2 As shown, the pipe 1 is located between the upper guide wheel group and the lower guide wheel group, the upper guide wheel group includes two upper guide wheels 19, the lower guide wheel group includes two lower guide wheels 20, the fixed plate 7 corresponds to the two upper guide wheels 19 and has two upper movable grooves 21, and the fixed plate 7 corresponds to the two lower guide wheels 20 and has two lower movable grooves 22, and the length direction of the upper movable grooves 21 and the lower movable grooves 22 are extended along the first direction; the first direction is Figure 1 Middle vertical direction;

[0039] On the side wall of the fixed plate 7 away from the pipe 1, a first mounting plate 23 is fixedly arranged on the top thereof corresponding to the upper movable groove 21, and a first elastic member 24 is fixedly connected to the bottom of the first mounting plate 23. Optionally, the first elastic member 24 is a spring, and the length direction of the first elastic member 24 extends along the first direction. A first rotating seat 25 is fixedly connected to the bottom thereof, and a first rotating shaft 26 is arranged on the first rotating seat 25. One end of the first rotating shaft 26 passes through the upper movable groove 21 and extends to a side of the fixed plate 7 close to the pipe 1, and an upper guide wheel 19 is rotatably sleeved;

[0040] On the side wall of the fixed plate 7 away from the pipe 1, a second mounting plate 27 is fixedly arranged at its bottom corresponding to the lower movable groove 22, and a second elastic member 28 is fixedly connected to the top of the second mounting plate 27. Optionally, the second elastic member 28 is a spring, and the length direction of the second elastic member 28 extends along the first direction. A second rotating seat 17 is fixedly connected to the top thereof, and a second rotating shaft 13 is arranged on the second rotating seat 17. One end of the second rotating shaft 13 passes through the lower movable groove 22 and extends to a side of the fixed plate 7 close to the pipe 1, and a lower guide wheel is rotatably sleeved;

[0041] The pipe 1 is located between the upper guide wheel 19 and the lower guide wheel 20, and the top and bottom of the pipe 1 are movably abutted against the upper guide wheel 19 and the lower guide wheel 20 respectively. Through the elastic force of the first elastic member 24 and the second elastic member 28, the upper guide wheel 19 and the lower guide wheel 20 are both in contact with the pipe 1 and fit the pipe 1, so that the pipe 1 can be smoothly conveyed and the pipe 1 can be prevented from jumping. At the same time, it can adapt to pipes 1 of different diameters.

[0042] A supporting device, which is located between the pipe reel and the detection device, includes a supporting column 11, and two slide grooves 12 extending along a first direction are provided on the side wall of the supporting column 11 close to the pipe 1. Optionally, the slide groove 12 is a T-shaped slide groove, and a slider is slidably arranged in the slide groove 12, which can be a T-shaped slider corresponding to the T-shaped slide groove. Two third rotating shafts 14 are arranged on the slider along the first direction, and a supporting wheel 15 is rotatably arranged on the third rotating shaft 14, and the two supporting wheels 15 on each slider are respectively located on the upper and lower sides of the pipe 1, so as to support the pipe 1;

[0043] A telescopic sleeve 16 extending along the first direction and capable of extension and contraction is provided at the bottom of the slider. The top and bottom of the telescopic sleeve 16 are fixedly connected to the bottom of the slider and the bottom of the slide groove 12 respectively. A third elastic member is provided in the telescopic sleeve 16. Optionally, the third elastic member is a spring for supporting the slider.

[0044] Working principle: After the tube 1 is produced, it is transported by the feeder and finally rolled up by the tube reel. During this process, it needs to be detected by the detection device. The detection bead 2 is located in the moving tube 1. The iron powder core 5 inside it and the magnet 8 attract each other to ensure that the detection bead 2 will not be taken away by the tube 1 when the tube 1 moves. The detection probe 9 can detect the detection bead 2;

[0045] When the inner diameter of the pipe 1 becomes smaller, the detection bead 2 will be stuck inside the pipe 1 and thus carried away by the pipe 1. At this time, the detection probe 9 cannot detect the detection bead 2, and an alarm will be sounded through the alarm, and the equipment will be shut down through the external controller, so that the staff can take out the detection bead 2 and scrap and crush the pipe 1 that does not meet the specifications.

[0046] If the staff forgets to test the beads 2, they will directly scrap and crush the pipes 1 that do not meet the specifications. The layered structure of the PE material of the test beads 2 and the iron powder core 5 filled inside will not damage the cutter and avoid damaging the cutter blade, thereby saving costs and avoiding financial and material losses. At the same time, the layered structure of the PE material is also convenient for cutting and crushing.

[0047] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with (but not limited to) technical features with similar functions disclosed in the present application.
