[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] The continuous hitting alarm system of this application can detect flaws in the copper pipe by the flaw detection box 8 and the flaw detection head 9, give an alarm reminder for the damage points, and perform continuous hitting alarm operations on the continuously occurring or damage points with excessive damage degree, which is convenient for distinguishing and reminding from ordinary damage points. This alarm part is an existing program, and this application will not describe it in detail.

[0024] The improvement point of this application is: changing the detection form of the damage points of large loose coil copper pipes to improve the flaw detection efficiency of large loose coil copper pipes. A further purpose of this application is to set adjustable feeding rollers 4 to adapt to large loose coil copper pipes of different sizes (large loose coils formed by winding copper pipes of different diameters).

[0025] The first transmission motor 13 (model number YS7134) and the second transmission motor 17 (model number GV50 - 3.7KW - 60 - S) mentioned in the present invention can both be obtained by purchasing from the market.

[0026] As Figures 1-4 shown, this application discloses a continuous hitting alarm system for damage points of large loose coil copper pipes, including a flaw detection installation box 1. There are multiple large loose coil winding frames 20 on the outer side of the flaw detection installation box 1. The rotating shaft of the large loose coil winding frame 20 is driven by a stepping motor. There are feeding ports 2 on both sides of the flaw detection installation box 1. The large loose coil winding frame 20 is located on one side of one of the feeding ports 2. There are two groups of guiding and clamping devices in the flaw detection installation box 1. Each group of guiding and clamping devices includes two relatively arranged feeding rollers 4. The two feeding rollers 4 in each group of guiding and clamping devices are located on the upper and lower sides of the feeding port 2 to clamp the copper pipes entering and leaving through the feeding port 2. There is a material guiding seat 5 in the flaw detection installation box 1. There are multiple material guiding grooves on the material guiding seat 5. There is a flaw detection box 8 above the material guiding seat 5 in the flaw detection installation box 1. There are multiple flaw detection heads 9 in the flaw detection box 8.

[0027] The material inlet 2 on the right side of this application is the feed inlet, and the one on the left side is the discharge outlet. The large loose coil winding rack 20 is arranged on the left side of the material inlet 2 on the left side. A bending device can be arranged between the large loose coil winding rack 20 and the material inlet. The bending device can adopt existing devices, and this application will not elaborate further.

[0028] When this application is in use, the large loose coil winding rack 20 is driven by a stepping motor, which can precisely control the winding of the large loose coil. One end of the copper tube enters the flaw detection installation box 1 through the material inlet 2. At this time, two sets of guiding and clamping devices on both sides of the material inlet, each set containing two material conveying rollers, work together to clamp the copper tube up and down to ensure that it passes through the detection area smoothly and linearly, avoiding unnecessary twisting or damage during the conveying process. Under the guidance of the guiding and clamping devices, the copper tube continues to move forward to the material guiding seat 5. The multiple material guiding grooves on the material guiding seat are designed to further guide the copper tube to travel along a predetermined path to ensure precise alignment during the flaw detection process. When the copper tube passes through the material guiding seat, it enters the detection area of the flaw detection box 8 located directly above it. The flaw detection box is internally provided with multiple flaw detectors 9. The flaw detectors can adopt eddy current flaw detection technology to quickly and continuously scan the defects on the inner and outer surfaces and near-surface of the copper tube, and detect in real time the possible crack points, inclusions, deformations and other damage points on the copper tube. When the flaw detector detects a damage point, continuous stamping alarm is carried out. The continuous stamping alarm is an alarm operation for continuously appearing or damage points with excessive damage degree, which is convenient for distinguishing from ordinary damage points and serving as a reminder.

The transmission plate 12 is connected to the flaw detection installation box 1 through a support spring 11. The transmission plate 12 is in a swinging state relative to the axis of the positioning rod 14. The transmission plate 12 is connected to the limit post 6 through a shock pad 7, so that the limit post 6 can limit and damp the transmission plate 12 through the shock pad 7, avoiding the rebound of the transmission plate 12.

[0034] Please refer to Figure 2 and Figure 4 , on the side of the installation vertical plate 16 away from the material conveying roller 4, a second driving motor 17 is fixedly installed. The output end of the second driving motor 17 is connected to a driving screw rod 19 through a coupling. On the outer side of the middle part of the driving screw rod 19, a driving seat 18 is installed. On one side of the installation vertical plate 16, a kidney-shaped hole is provided.

The driving screw rod 19 is threadedly connected to the driving seat 18. One end of the other two material conveying rollers 4 is rotatably connected to the installation vertical plate 16 through a bearing. The second driving motor 17 drives two of the material conveying rollers 4 where the driving seat 18 is located to move vertically through the driving screw rod 19, and thus the distance between two adjacent material conveying rollers 4 can be adjusted.

The copper tube in a straight tube state is guided by the material conveying rollers 4 and the material guiding seat 5 and then enters the large loose coil winding frame 20 for winding to form a large loose coil.

[0037] During the copper tube conveying process, the first transmission motor 13 is started, and a toggle bar is provided on the side of the toggle plate 15, so that the first transmission motor 13 drives the toggle bar to rotate clockwise through the toggle plate 15 under the support of the flaw detection installation box 1, and then the toggle plate 15 presses down the end of the transmission plate 12 through the toggle bar, so that the transmission plate 12 rotates counterclockwise relative to the positioning rod 14. When the toggle bar is separated from the transmission plate 12, the transmission plate 12 drives the flaw detection box 8 to rotate clockwise under the support of the support spring 11, and then the flaw detection box 8 drives the flaw detection head 9 to swing for flaw detection. The present application can perform two modes of flaw detection, one is static flaw detection, that is, the flaw detection box 8 and the flaw detection head 9 are static for flaw detection of the copper tube. The other is swing flaw detection, and the flaw detection box 8 is driven to swing by the toggle plate 15.
