Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment. Background Art

[0002] Bamboo products are a common household item in people's daily lives, such as some decorations and utensils. Using bamboo products to make them is not only more antiseptic and antibacterial, but also more environmentally friendly.

[0003] In the production and processing of bamboo products, it is necessary to cut the original bamboo. During the cutting process of the original bamboo, the bamboo joints are usually cut off together for use. However, some bamboo products often do not require bamboo joints. Therefore, the bamboo tubes cut by traditional cutting equipment need to be processed again before they can be used, which affects production efficiency. In order to solve this problem, some equipment in the prior art uses visual photography technology to detect the original bamboo before cutting, so as to achieve the purpose of removing bamboo joints. However, this type of cutting equipment usually has limited effect on limiting the position of the original bamboo. For example, the patent technology with announcement number CN115534025B discloses a fixed-length cutting and bamboo joint intelligent identification device and an automated production equipment for original bamboo. When sawing, the air pump assembly located above the original bamboo pushes the piston rod at the front end of the air pump assembly against the upper end of the original bamboo through the air pressure of the cylinder, applying a constant pressure to the original bamboo. Although this method can limit the cut end of the original bamboo, the pressure is limited, and if the cut end is long, it will shake, affecting the cutting effect. Utility Model Content

DETAILED DESCRIPTION

[0025] See Figure 1-Figure 7As shown, the technical solution adopted in this specific embodiment is: it includes a frame 1, the feeding end of the frame 1 is provided with a clamping feeding mechanism 2, the discharging end of the frame 1 is movably provided with 3, the frame 1 is provided with a cutting mechanism 4 close to the clamping feeding mechanism 2, and the frame 1 is provided with a CCD visual detection device 6 above the clamping feeding mechanism 2. The clamping feeding mechanism 2 includes a clamping roller group and a clamping drive mechanism. The clamping roller is vertically arranged above the clamping drive mechanism. The clamping and picking mechanism 3 corresponds to the position of the clamping roller. In traditional cutting mechanisms, usually only the feeding end is fixed and then cutting is performed, and the fixing method is mostly one-way pressing and limiting. The fastening effect is general and it is easy to move during cutting, affecting the cutting effect. In addition, there is a lack of effective identification and detection mechanism to detect bamboo nodes. Therefore, in this embodiment, the nanmu chopstick blank is used. Taking cutting as an example, a CCD visual inspection device is set in the cutting mechanism to inspect the raw bamboo of nanmu. According to the shooting and identification situation, the central control system issues a conveying length instruction. The part without bamboo nodes is conveyed to the specified length through the clamping and feeding mechanism according to production requirements. At the same time, the clamping and picking mechanism cooperates to move to clamp the bamboo tube to be cut. After clamping is completed, the cutting mechanism starts to cut the raw bamboo. The cut bamboo tube is still clamped by the clamping and picking mechanism. At this time, it moves to the top of the qualified product conveyor belt and puts the qualified product without bamboo nodes for conveying. When bamboo nodes are detected, the length of the bamboo nodes is determined and the corresponding length is conveyed to reduce the waste of raw materials. Similarly, the bamboo node part is cut. After cutting is completed, the clamped bamboo node moves to the top of the waste conveyor belt, and the bamboo node is put down for waste conveying. The cutting of the finished product without bamboo nodes and the cutting of the bamboo node part can be completed quickly.

[0026] Specifically, by setting up a clamping roller group, the raw bamboo can be clamped and fixed more firmly. When the CCD visual inspection device completes the inspection, the clamping drive mechanism drives the clamping roller group to rotate to transport and cut the raw bamboo, and the clamping and picking mechanism moves synchronously to clamp the transported raw bamboo before cutting. After cutting is completed, the clamping and picking mechanism still takes away the partition for transportation. The double clamping structure of this embodiment is used to clamp and fix the raw bamboo in two directions, which can effectively clamp the raw bamboo, ensure stability during cutting, and ensure that the cut bamboo sections can be accurately placed.

The detection end is provided with a detection chamber to shoot and detect the bamboo nodes of the raw bamboo, and feed the detection results back to the control center. The control center outputs cutting instructions, controls the specific raw bamboo conveying length for cutting, and divides the cutting into qualified product cutting and waste cutting. The cut finished products and waste products are sent out from the discharge end, clamped by the clamping and picking mechanism, and lowered for transmission in partitions. The fully automatic cutting operation greatly improves the cutting accuracy and cutting speed, and improves the cutting efficiency.
