Description

TECHNICAL FIELD

[0001] The utility model relates to plastic tubular product detection technical field especially a plastic tubular product detection line marking device. BACKGROUND

[0002] Plastic tubular product is the tubular product of extrusion molding after adding auxiliary agent with synthetic resin as main raw material, and is widely used in many fields because of light weight and corrosion resistance. In the production process, the detection line marking device is extremely critical. It can detect the appearance quality of the tubular product, scan the surface of the tubular product through the sensor, find defects such as flaws and bubbles in time and send signals, so as to facilitate the processing of unqualified products. At the same time, for the tubular product that needs to be marked, the line marking device can accurately draw size, specification and other marking lines according to the preset program, which provides convenience for subsequent cutting, processing and marking, ensures that the tubular product meets the standard and customer demand, effectively improves the production efficiency and product quality, and guarantees the smooth progress of the production process.

[0003] In the patent with the publication number CN218427815U, a plastic tubular product detection line marking device is mentioned. Two support columns are provided with clamping assemblies on the inner side of the upper part for clamping and fixing the plastic tubular product body. The third motor drives the clamping assembly to rotate through the rotating rod. The first motor drives the support block to move left and right through the first transmission assembly. The second motor is arranged inside the support block. The second motor drives the line marking pen to move up and down through the second transmission assembly. The plastic tubular product is clamped and fixed by the clamping assemblies on the two support columns. Then the first motor drives the line marking pen to move left and right through the first transmission assembly. The second motor drives the line marking pen to move up and down through the second transmission assembly. The third motor drives the plastic tubular product to rotate through the rotating rod. In this way, automatic clamping and line marking of the plastic tubular product are realized, which can reduce the labor workload.

[0004] The inventors have found that the prior art has at least the following problems:

[0005] The above-mentioned existing plastic tubular product detection line marking device can only insert the plastic tubular product between the two fixed blocks before line marking detection, which limits the length of the tubular product to be detected to be just the distance between the two fixed blocks, thereby limiting the scope of application.

[0006] In addition, multiple motors are needed to contact the line marking pen with the tubular product during line marking, which not only increases the use cost, but also cannot provide buffering during the lifting of the line marking pen, thereby easily damaging the line marking pen.

[0007] Therefore, the above technical problems need to be solved. UTILITY MODEL CONTENTS

[0008] The purpose of this invention is to provide a plastic pipe inspection marking device to solve the problems of limited applicability, high cost, and easy damage to marking pens in the prior art.

[0018] I. This utility model, through the cooperation of a drive mechanism, a guide mechanism, a marking mechanism, and an auxiliary mechanism, allows the auxiliary mechanism to provide primary support when the length of the tube is less than the distance between two drive mechanisms, and provides secondary support when the length of the tube is greater than the distance between them.

Figure 1 For the sake of accuracy, the specific details should be as follows: Figure 1 The left side is the front. Figure 1 The right side is the rear; at the same time, as Figure 2 As shown, the horizontal direction is roughly defined as left and right, and the vertical direction is defined as up and down. If a specific orientation changes, the directional indication will also change accordingly.

[0034] This utility model provides a plastic pipe inspection marking device, including a base 1, a drive mechanism 2, a guide mechanism 3 and a marking mechanism 4, with an auxiliary mechanism 5 provided below the marking mechanism 4;

[0035] The drive mechanism 2 includes two symmetrical semi-ring seats 21 and a pair of guide rods 28 fixedly connected between the two semi-ring seats 21. A pair of symmetrical mounting seats 23 are fixedly connected to the inner side of the semi-ring seats 21.

[0036] The guide mechanism 3 includes a guide rail 31 and slide plates 32 located below both ends of the guide rail 31. Pressure sensors 36 are installed on the top of each slide plate 32.

[0037] The marking mechanism 4 includes a damping slider 41 and a mounting cylinder 44 rotatably connected below the damping slider 41. A marking pen 46 is inserted and mounted on one side of the mounting cylinder 44.

[0038] The auxiliary mechanism 5 includes an arc-shaped support plate 51 and auxiliary rollers 52 that are symmetrically connected and rotatably connected above the arc-shaped support plate 51;

[0039] The base 1 also includes a PLC control unit for operating the telescopic cylinder 27 and the drive motor 25, and for receiving feedback from the pressure sensor 36.

[0040] A semi-annular groove 22 is provided on the inner side of the semi-annular seat 21, and the mounting seat 23 is installed on the inner wall of the semi-annular groove 22; the pressure sensor 36 is a conventional and universal sensor.

[0041] In a further embodiment, a drive wheel 24 is rotatably connected above each mounting base 23, and a drive motor 25 is mounted on one side of one of the mounting bases 23, with the output end of the drive motor 25 connected to the drive wheel 24.

[0042] In this embodiment, the included angle between the mounting bases 23 is 60 degrees; when the tube 6 is placed above the drive wheel 24 and the drive motor 25 is operated, the tube 6 can be driven to rotate; the output end of the drive motor 25 has a gear and meshes with the gear of the rotation shaft of the drive wheel 24 inside the mounting base 23, thereby driving the drive wheel 24 to rotate.

[0043] In a further embodiment, a support frame 26 is fixedly connected above each of the semi-ring seats 21, and a telescopic cylinder 27 is installed above each of the support frames 26. The output end of the telescopic cylinder 27 is connected above both ends of the guide rail 31.

[0044] In this embodiment, the inner sidewall of the support frame 26 is provided with a slide rail, and the two ends of the slide plate 32 are slidably connected in the slide rail of the inner sidewall of the support frame 26.

[0045] In a further embodiment, a positioning wheel 33 is rotatably connected to the bottom of the slide plate 32, and a limiting post 34 is fixedly connected to the top of the slide plate 32. The limiting post 34 passes through the guide rail 31, and a spring 35 is provided around the periphery of the limiting post 34. The spring 35 is located below the guide rail 31.

[0046] In this embodiment, the positioning wheel 33 can be passively rotated when the tube body 6 rotates. The operation of the telescopic cylinder 27 will first make the positioning wheel 33 contact the tube body 6, and at this time the compression of the spring 35 can act as a buffer.

[0047] In a further embodiment, the damping slider 41 is slidably connected to the inner side of the guide rail 31, and a connecting block 42 is fixedly connected to one side of the damping slider 41. A connecting rod 53 is inserted into the inside of the connecting block 42, and the bottom end of the connecting rod 53 fits the arc-shaped support plate 51.

[0048] In this embodiment, the damping slider 41 is composed of symmetrical T-shaped blocks, with the lower T-shaped block connected to the ear plate 43. When the tube 6 is too short, the plug rod 53 can be inserted from the top of the connecting block 42 and embedded into the top of the arc-shaped support plate 51, so that when the marking mechanism 4 is moved, the auxiliary mechanism 5 will move together, making it more convenient to use.

[0049] In a further embodiment, an ear plate 43 is fixedly connected to the lower part of the damping slider 41, and a damping shaft 45 is installed on one side of the mounting cylinder 44. The damping shaft 45 is rotatably connected to the inside of the ear plate 43.

[0050] In this embodiment, the damping shaft 45 is inserted into the inside of the ear plate 43, thus providing a certain resistance, thereby maintaining a certain angle after rotation.

[0051] In a further embodiment, the guide rod 28 passes through the arc-shaped support plate 51.

[0052] In this embodiment, the arc-shaped support plate 51 is restricted by the guide rod 28, so that it can slide left and right in the middle of the semi-ring seat 21, thereby allowing the auxiliary roller 52 above it to assist in supporting the tube body 6 or provide main support when the tube body 6 is not long enough; the position of the auxiliary roller 52 coincides with the drive wheel 24 when viewed from the side.

[0053] The working principle of this utility model is as follows:

[0054] When it is necessary to inspect and scribing the tube body 6, the tube body 6 can be inserted between the left and right semi-ring seats 21 and the support frame 26 and placed above the drive wheel 24. Then, the scribing mechanism 4 is pushed to the desired scribing area as needed. Then, the telescopic cylinder 27 is operated by the external PLC controller, which causes the guide rail 31 to move down with the scribing mechanism 4. During the downward movement of the guide rail 31, the slide plate 32 moves along with it. When the positioning wheel 33 contacts the top of the tube body 6, the spring 35 will be compressed until the bottom of the guide rail 31 contacts the pressure sensor 36, which will then provide feedback to the PLC control. The device then stops the telescopic cylinder 27 and starts the drive motor 25, which in turn allows the tube 6 to start rotating. At this time, the mounting cylinder 44 can be rotated downward so that the marking pen 46 contacts the tube 6 at a tangential angle for inspection and marking. During this process, the auxiliary roller 52 above the arc-shaped support plate 51 will also rotate at the same time. This not only provides support for the rotating tube 6 when marking, but also allows the auxiliary mechanism 5 to act as the main support for the short tube 6 when dealing with short tubes 6 by inserting the connecting rod 53 above the arc-shaped support plate 51 and moving it together with the marking mechanism 4. This expands the applicability of the auxiliary mechanism 5.

[0055] When performing inspection marking, the marking pen 46 is made to contact the tube body 6 at a tangential angle, which avoids damage to the marking pen 46 by vertical marking. At the same time, there is no need to use multiple motors to drive the marking pen 46, thereby reducing the cost of use.

[0056] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
