Description

Technical Field

[0001] The utility model belongs to the field of bamboo processing, and in particular relates to a bamboo node removal component and a bamboo processing device thereof. Background Art

[0002] Bamboo products refer to products made with bamboo as the processing raw material. Most of them are daily necessities, such as bamboo baskets, bamboo screens, bamboo beds, bamboo stools, etc. In recent years, bamboo floors and bamboo furniture have become more popular. There are also some higher-value folk crafts such as bamboo carvings.

[0003] When producing bamboo products, it is sometimes necessary to cut bamboo into multi-node bamboo tubes, which requires removing the bamboo nodes between two adjacent bamboo tubes. The bamboo nodes are usually removed by cutting to obtain multi-node bamboo tubes. To ensure the stability of the cutting process, multi-point pressing and fixing is required when the bamboo is cut. However, bamboo is not purely linear, and the bending degrees of different bamboos are different. Therefore, when performing multi-point fixing, the pressing position needs to be adjusted according to the bending condition of the bamboo. For this purpose, a bamboo node removal component is proposed. Utility Model Content

[0031] like Figure 3As shown, the clamping plate mechanism 2 includes two clamping plates 21 that can synchronously slide in opposite directions. The two clamping plates 21 are synchronously approached to clamp the bamboo tube in the center to achieve preliminary positioning of the bamboo tube.

[0032] In this embodiment, the two clamping plates 21 are slidably connected to the workbench 1, and two first fixed plates 22 are fixed at the lower end of the workbench 1. A first screw rod 23 is rotatably connected between the two second fixed plates 22. The first screw rod 23 is provided with a first external thread 231 and a second external thread 232 with opposite rotation directions and equal pitches. The first external thread 231 and the second external thread 232 respectively penetrate the two clamping plates 21 and are threadedly connected thereto. By rotating the first screw rod 23, the bamboo tube can be centrally clamped to complete the preliminary central positioning.

[0033] In order to ensure stable clamping of the bamboo tube, the first screw rod 23 needs to have self-locking properties, that is, the thread lead angle of the first external thread 231 and the second external thread 232 is smaller than the equivalent friction angle;

[0034] Of course, the method of driving the two clamping plates 21 to slide synchronously in opposite directions includes but is not limited to the first screw rod 23 in this embodiment. In some embodiments, two hydraulic cylinders can be arranged on the workbench 1 to drive the two clamping plates 21 to slide synchronously in opposite directions respectively.

[0035] The first pressing plate mechanism 3 is located directly above the clamping plate mechanism 2 and is used to press the clamping plate 21 at the center of the clamping position.
