Problems solved by technology

[0004] In the lotus seed coring machine that can adapt to the size of lotus seeds, the center distance of the centering roller axis cannot be adjusted, so that the diameter of the centering roller cannot be changed much. The influence of the diameter of the centering roller on the centering effect is studied
The actual centering rate of lotus kernel rolling centering cannot be detected online, the actual axial feed force cannot be detected online when drilling, and the actual centering accuracy cannot be measured

Embodiment Construction

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0034] Such as figure 1 — Figure 7, the lotus kernel rolling centering test bench of the present invention includes a frame 1, a feeding mechanism, a rolling centering module, a centering module, a centering process parameter adjustment module, a centering rate online detection module, and a drilling axial feed force detection module, centering accuracy detection module and PLC control system.

[0035] The feeding mechanism is used to send lotus kernels to the rolling centering module, including a feeding trough 5, a feeding trough mounting plate 6, an electromagnet 43, and a material retaining plate 44. The feeding trough mounting plate is installed above the middle part of the frame 1, and the feeding trough 5 is installed on the front of the feeding trough mounting plate 6 at a certain inclination angle, on the side of the center distance adjustment mec...

Abstract

The invention discloses a test bench for lotus kernel rolling centering, which is mainly used for testing influences of centering rollers with different diameters and different rotation speeds and a centering roller center distance on the lotus kernel centering effects, the centering rate and the centering precision. Devices such as a stepping motor, a laser displacement sensor, and a pull pressure sensor are adopted; the stepping motor is used as a centering roller driving part; the test bench can accurately test influence laws by the different rotation speeds of the centering rollers on the lotus kernel centering rate and the centering precision and by the different diameters and different center distances of the centering rollers on the centering effects; the laser displacement sensor is used as a detection element for the centering rate and the actual lotus kernel centering precision, and high-precision non-contact measurement on the lotus kernel rolling centering rate online detection and the lotus kernel centering precision can be realized; and the pull pressure sensor is used as an axial feed force detection element in the case of core drilling, and online actual axial feed force detection in the case of core drilling is realized. The test bench has multiple measurement subjects and the precision is high, and the tested data can provide reference for developing a lotus kernel de-centering device.

Description

technical field [0001] The invention mainly relates to a test device for food processing equipment, in particular to a test stand for rolling and centering lotus kernels. Background technique [0002] In the processing of lotus kernels, a very important process is to center and align the lotus kernels so that the axis of the lotus kernel is coaxial with the axis of the processing tool, so as to ensure that the lotus kernel is completely removed. However, in actual production and processing, it is difficult to guarantee The axis of the lotus heart is coaxial with the axis of the drill flower, which causes the processing tool to deviate and fails to achieve the purpose of heart removal. The rolling centering method is a commonly used centering method in lotus seed heart-removing processing machinery. The quality of the centering effect directly affects the heart-removing quality of lotus kernels. [0003] The invention patent No. 201310034388.2 provides a lotus seed coring ma...
