Embodiment 1

[0021] Such as figure 1 and figure 2 A device for testing the bending strength of bamboo slices by an ultrasonic motor as shown, comprising a test platform 1 and an ultrasonic motor 2, one end of the test platform 1 is provided with an in-position sensor 3 and a pressure block 5 for fixing one end of the bamboo slice 4, and the other end of the test platform 1 One end is provided with a level sensor 6; the mover 7 of the ultrasonic motor 2 is provided with a test head 8, and a force sensor is provided on the test head 8; the in-position sensor 3, the level sensor 6 and the test head 8 are connected with intelligent control equipment. The intelligent control device is preferably a computer 9 . Ultrasonic motor 2 has a fast response speed, which can improve the test accuracy to a limited extent without adding other mechanisms; compared with ordinary electromagnetic motors, when the level sensor detects that the bamboo piece is attached to the platform, the motor can stop quick...

Embodiment 2

[0025] A method for testing the bending strength of bamboo slices by an ultrasonic motor, comprising the steps of:

[0026] Step 1, using a pressing block 5 to fix one end of the bamboo sheet 4 on the test platform 1;

[0027] Step 2, the mover 7 of the ultrasonic motor 2 drives the test head 8 to press down the other end of the bamboo slice 4 until the level sensor 6 detects that the other end of the bamboo slice 4 is attached to the upper surface of the test platform 1;

[0028] Step 3, the intelligent control device obtains the straightening strength of the bamboo slices 4 through the force sensor.

[0029] The bamboo slices 4 are transported to the test platform 1 through the automatic transmission belt; at this time, the position sensor 3 detects the bamboo slices, and after measuring the straightening strength, the automatic transmission belt transports the bamboo slices 4 to the corresponding storage box.

[0030] The intelligent control device is preferably a computer...

Abstract

The invention discloses an apparatus and method for testing the bending strength of a bamboo chip by using an ultrasonic motor. The apparatus comprises a test platform and the ultrasonic motor, wherein one end of the test platform is provided with an in-place sensor and a press block used for fixing one end of the bamboo chip, the other end of the test platform is provided with a horizon sensor, a mover of the ultrasonic motor is provided with a measuring head, a force transducer is mounted on the measuring head, and the in-place sensor, the horizon sensor and the measuring head are connected with intelligent control equipment. The apparatus and method can rapidly and accurately detect the aligning strength of bamboo chips, are beneficial for combination of bamboo chips with small and similar aligning strength into a bamboo plate, and enable the amount of needed glue to be decreased, heating temperature and pressurization time to be reduced, energy to be saved, cost to be lowered and process refinement to be realized.

Description

technical field [0001] The invention belongs to the electrical field, in particular to a device and method for testing the bending strength of bamboo slices by an ultrasonic motor. Background technique [0002] Explanation of terms: Bending strength and straightening strength of bamboo slices-------Bamboo slices will be bent. To straighten the bent bamboo slices, it is called straightening strength. This value is defined to be equal to the bending strength, that is, the same Different representation names for properties. [0003] Straightening process ------ After sticking the bamboo slices with glue to form a bamboo board, put it into a straightening machine (press) with a little pressure and temperature, and keep it for a certain period of time to make the bamboo board permanently flat . [0004] Due to the long growth cycle of the wood used in furniture, it is a good way to replace it with bamboo. However, due to the small size of bamboo chips, it is necessary to use ch...
