Description

Technical Field

[0001] This utility model relates to the field of bamboo conveying technology, and in particular to a bamboo conveying and screening device. Background Technology

[0002] Bamboo products come in a wide variety of types, including common ones such as bamboo chopsticks, bamboo mats, bamboo curtains, and bamboo chairs. Almost all of these involve the production of long and thin bamboo strips. Bamboo strips are widely used as raw materials for bamboo product processing. In the bamboo strip processing stage, splitting bamboo is an essential step, which is usually done by a bamboo splitting machine. The bamboo splitting machine can split bamboo tubes into bamboo strips, making them the raw bamboo strips needed for subsequent processing. When splitting bamboo, the required bamboo tubes are usually selected according to the needs.

[0003] Existing bamboo screening processes mostly involve manual screening and cutting of bamboo before further cutting. However, the bamboo cutting process into bamboo strips now typically uses automated feeding methods. Traditionally, the screening of bamboo tube diameter and edge thickness is done before the bamboo enters the splitting process. Because manual handling and screening of both ends of the bamboo during loading and processing often leads to interruptions in the loading process, significantly impacting efficiency. Furthermore, the workload is heavy, and manual screening of tube diameter and edge thickness is prone to errors, resulting in the production of substandard bamboo strips and increasing the workload of subsequent secondary screening. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to provide a bamboo conveying and screening device that can detect the thickness of bamboo tubes and screen bamboo tubes.

[0005] This utility model is implemented using the following method: A bamboo conveying and screening device includes a roller conveyor belt. A screening component is provided at the right end of the roller conveyor belt, and a detection component is provided at the left end of the roller conveyor belt. The detection component includes a support frame. The support frame is embedded between two rollers at the left end of the roller conveyor belt. A first telescopic cylinder is embedded in both the upper and lower horizontal plates of the support frame. A limit block is provided at the end of the telescopic rod of the first telescopic cylinder. A connecting plate is provided on the right side of the upper horizontal plate of the support frame. A second telescopic cylinder is embedded in the connecting plate. A first measuring block is provided at the end of the telescopic rod of the second telescopic cylinder. A rotating plate is hinged to the end of the connecting plate, and a first motor for driving the rotating plate to rotate is provided on the connecting plate. A strip-shaped groove is opened in the middle of the lower surface of the rotating plate. A second motor is provided in the strip-shaped groove. A screw is connected to the output end of the second motor. A second measuring block is spirally sleeved on the screw. An infrared distance sensor is provided at the right end of the lower surface of the first measuring block, and an infrared receiver corresponding to the infrared distance sensor is provided at the right end of the upper surface of the second measuring block.

[0006] Furthermore, the screening component includes a third telescopic cylinder, which is embedded in the right end of the front support plate of the roller conveyor belt. A screening push plate is provided at the end of the telescopic rod of the third telescopic cylinder, and a guide conveying plate that cooperates with the screening push plate is embedded in the right end of the rear support plate of the roller conveyor belt.

[0007] Furthermore, a screw is spirally embedded at the end of the rotating plate, and a limiting block for limiting the bamboo is provided at the end of the screw. A pressure sensor is embedded on the left side of the limiting block.

[0008] The beneficial effects of this utility model are as follows: This utility model incorporates a screening component and a detection component into the device, enabling it to replace manual screening of the tube edge thickness, greatly reducing the amount of manual material feeding. Furthermore, the screening component allows for screening of bamboo after feeding but before it enters the bamboo splitting machine, removing bamboo that does not meet the splitting requirements, thus optimizing the bamboo screening process. This reduces manual labor while improving the accuracy and efficiency of bamboo screening, significantly increasing the efficiency of bamboo cutting. This utility model has a simple structure, is easy to operate, and effectively saves manpower and resources, improving work efficiency. Attached Figure Description
