Description

Technical Field

[0001] This utility model relates to the technical field of corrugated pipe conveying device with positioning and opening / closing function, and in particular to a corrugated pipe conveying device with positioning and opening / closing function. Background Technology

[0002] The corrugated pipe conveying device with positioning and opening / closing functions is a complex system composed of several key parts. These parts work together to achieve stable conveying, precise positioning, and safety protection of the corrugated pipe.

[0003] The existing V-groove conveyor mechanism does not have digital positioning and opening / closing functions. When the upper robotic arm picks up the material, it cannot prevent the V-groove conveyor belt from being compressed during the material picking process, resulting in inaccurate positioning after the pipe material is conveyed to the correct position.

[0004] To address this issue, we propose a corrugated pipe conveying device with positioning and opening / closing functions. Utility Model Content

[0005] The purpose of this invention is to provide a corrugated pipe conveying device with a positioning and opening / closing function. When using this device, the V-groove can be set to open / close according to the pipe diameter. A guide spring reset mechanism is added to prevent the conveyor belt from being compressed when the robotic arm picks up material, thereby significantly reducing the failure rate of the conveying and V-groove opening / closing positioning devices. A pipe presence / absence detection switch is provided to detect the presence / absence of the pipe and the gap between the pipe and the baffle plate, ensuring accurate pipe positioning and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A corrugated pipe conveying device with positioning and opening / closing functions includes a frame. A conveyor belt motor is installed at the bottom left side of the frame, and a conveyor belt is installed at the output shaft of the conveyor belt motor. Detection switches are installed on the supports on both sides of the conveyor belt. An opening / closing plate is installed on the right side of the frame, and an opening / closing servo motor is installed at the center of the rear of the frame. The opening / closing servo motor is connected to a bevel gear transmission box via a coupling. An opening / closing hydraulic transmission shaft is installed on the output end of the bevel gear transmission box. A baffle plate is fixedly installed above the end of the conveyor belt, and a spring guide mechanism is provided at the lower end of the conveyor belt. A compression spring is provided at the bottom end of the spring guide mechanism, and a guide rail is provided in the support of the spring guide mechanism. Ball screws are arranged parallel to each other on the guide rails on both sides of the conveyor belt.

[0008] In a further embodiment, the opening and closing hydraulic transmission shaft is rigidly connected to the ball screw via a coupling to achieve digital control of the opening and closing distance, with an adjustment accuracy of ±0.05mm.

[0009] In a further embodiment, an electrical control cabinet is also provided on the rack, in which a heat transfer device is installed, and the heat transfer device has a built-in temperature compensation module.

[0010] In a further embodiment, the surface of the baffle plate is provided with a wear-resistant coating, and a detection switch two is installed on the inner side of the baffle plate. The distance between the baffle plate and the detection switch two is adjustable by a fine-tuning bolt, and the detection accuracy is ±0.1mm.

[0011] In a further embodiment, the bevel gear transmission box adopts a dual output shaft design, and a synchronous belt is provided on the output shaft of the bevel gear transmission box. The two shafts are connected by the synchronous belt to ensure that the ball screws on both sides move synchronously.

[0012] In a further embodiment, the spring guide mechanism includes a compression spring and a guide rail, wherein the spring constant is 50 N / mm and the stroke is 10 mm.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention enables the V-groove to be set to open or close according to the diameter of the pipe when using the corrugated pipe conveying device with positioning and opening / closing function; it adds a spring-guided reset mechanism to prevent the conveyor belt from being pressed when the material-retrieving robot is picking up material, thereby significantly reducing the failure rate of the conveying and V-groove opening / closing positioning device; it is equipped with a pipe presence and positioning detection switch to detect the presence or absence of pipe material and the gap between the pipe and the baffle plate, ensuring accurate pipe positioning.
