Description

Technical Field

[0001] This utility model relates to the field of drying equipment, specifically a drying equipment for plastic pipe production lines. Background Technology

[0002] A drying device is a combination of mechanical equipment that uses certain technical means to dry the surface of an object of moisture or other liquids. It uses hot air as a medium to transfer heat to the material. During the flow of the hot air, heat is exchanged with the moisture on the surface of the material, causing the moisture to evaporate.

[0003] Chinese Patent No. CN202420951194.2 discloses a drying device for a plastic pipe production line, including a drying box. A support frame is provided at the lower end of the drying box. A feeding conveyor belt is provided inside the support frame. A motor is provided on the outer surface of the front end of the support frame. The motor is connected to the feeding conveyor belt. Multiple sets of feeding roller shafts are provided on the outer surface of the feeding conveyor belt. Fan housings are provided on both outer surfaces of the drying box. Two sets of drying fans are provided on one outer surface of each set of fan housings. Air outlets are provided on the other outer surface of each set of fan housings. The two sets of air outlets are located on the inner walls of both sides of the drying box. Multiple sets of guide fan blades are provided inside each set of air outlets. A base is provided on the outer surface of the upper end of the drying box. A top frame is provided on the upper end of the base. Six sets of drying ports are provided on the outer surface of the upper end of the base. Six sets of hot dryers are provided on the outer surface of the lower end of the top frame corresponding to the positions of the drying ports.

[0004] As can be seen from the above, the upper part of the drying oven also has a hot dryer to heat the pipes, resulting in a comprehensive and efficient drying effect. However, this solution still has the following shortcomings:

[0005] Firstly, the lack of real-time detection methods for the drying process makes it impossible to accurately determine whether the surface moisture of the pipes meets the standards, which can easily lead to incomplete drying or over-drying.

[0006] Secondly, the drying quality inspection relies on manual sampling, which is inefficient and carries the risk of missed inspections, making it difficult to meet the needs of automated production lines.

[0007] Therefore, a drying device for plastic pipe production lines is proposed to address the above-mentioned problems. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figures 1-5As shown, the drying device for a plastic pipe production line includes a main body 1, and a drying detection component 2 is provided on the top of the main body 1. The drying detection component 2 includes a detection frame 21, two CCD industrial cameras 22 are fixedly installed on the top of the detection frame 21, and two LED lights 23 are fixedly installed on the top of the detection frame 21. The drying detection component 2 also includes a fixed frame 24, a servo motor 25 is fixedly installed on one side of the top of the fixed frame 24, a first pulley 26 is fixedly installed at the output end of the servo motor 25, a transmission belt 27 is driven to the outer surface of the first pulley 26, and a second pulley 28 is driven to the other side of the transmission belt 27. The second pulley 28 is rotatably installed on one side of the fixed frame 24.

[0027] During operation, the pipe is fed into the drying chamber 14 by the conveyor belt 12 driven by the stepper motor 13. The drying chamber 14 dries the surface of the pipe through hot air circulation. After drying, the pipe moves to the bottom of the inspection frame 21 along the conveyor belt 12. At this time, the LED light 23 is turned on to provide uniform illumination for the CCD industrial camera 22. The two CCD industrial cameras 22 acquire high-definition images of the pipe surface from different angles, capturing in real time any residual moisture, water stains, or uneven drying on the pipe surface.

[0028] Furthermore, the drying detection assembly 2 also includes a movable plate 29, which is fixedly installed on one side of the transmission belt 27. A cylinder 31 is fixedly installed on the other side of the movable plate 29. A piston rod 32 is movably installed at the output end of the cylinder 31. A stamp 33 is fixedly installed on one side of the piston rod 32.

[0029] During operation, when the images captured by the CCD industrial camera 22 are analyzed by the PLC control system and it is determined that the pipe drying is substandard, the PLC sends a command to the servo motor 25 to drive the first pulley 26 to rotate. This drives the movable plate 29 to move laterally through the transmission belt 27, so that the stamp 33 is aligned with the position of the unqualified pipe. Then, the cylinder 31 is activated, and the piston rod 32 pushes the stamp 33 down to mark the unqualified mark on the surface of the pipe, which is convenient for subsequent sorting.

[0030] Furthermore, a slide rail 34 is fixedly installed on one side of the fixed frame 24, and a slider 35 is slidably installed on the slide rail 34. The slider 35 is fixedly installed on the back side of the movable plate 29.

[0031] During operation, as the movable plate 29 moves, the slider 35 slides synchronously within the slide rail 34, providing precise guidance for the movable plate 29 and preventing misalignment of the stamp 33 marking position due to movement deviation, thus ensuring marking accuracy.

[0032] Furthermore, the main body 1 includes a support frame 11, a conveyor belt 12 is fixedly installed on the top of the support frame 11, a stepper motor 13 is fixedly installed at the input end of the conveyor belt 12, and a drying chamber 14 is fixedly installed on the top of the conveyor belt 12.

[0033] During operation, the stepper motor 13 drives the conveyor belt 12 to rotate at a constant speed, ensuring that the pipe passes through the drying chamber 14 at a stable speed. The drying chamber 14 is equipped with heating elements and a fan to form circulating hot air, which evenly dries the surface of the pipe and avoids local overheating or incomplete drying.

[0034] Furthermore, a testing frame 21 is fixedly installed on the top of the support frame 11, and a fixing frame 24 is fixedly installed on the top of the support frame 11.

[0035] During operation, the installation of the support frame 11 facilitates the support of the testing frame 21 and the fixing frame 24.

[0036] Furthermore, it also includes a PLC control system, which is electrically connected to the CCD industrial camera 22, the servo motor 25, and the cylinder 31.

[0037] During operation, the CCD industrial camera 22 transmits real-time image data to the PLC control system. The system uses a preset image processing algorithm to determine the moisture content on the surface of the pipe and compares it with the set drying standard. If a defective product is detected, the PLC immediately controls the servo motor 25 to start, which drives the stamp 33 to move to the target position via the transmission belt 27. At the same time, the cylinder 31 is triggered to complete the marking action. The PLC monitors the speed of the servo motor 25, the downward stroke of the cylinder 31, and the acquisition frequency of the camera in real time to ensure that all components work together and realize fully automated closed-loop control of drying detection and marking.

[0038] Working principle: The pipe is fed into the drying chamber 14 by the conveyor belt 12 and then transferred to the inspection area. The CCD industrial camera 22 collects images of the pipe surface under the illumination of the LED light 23. The PLC control system analyzes and judges the drying quality. If it is unqualified, the servo motor 25 drives the movable plate 29 to move to the corresponding position, and the cylinder 31 drives the stamp 33 to mark, realizing the automated detection of the drying status and the marking of unqualified products.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
