Detailed Description

As shown in fig. 1-3, the food inspection instrument of the present invention comprises a mounting platform, a support 11 is disposed on the mounting platform, and a horizontally extending loading slot 12 is fixedly mounted at the upper end of the support 11; the upper end surface of the carrying groove 12 is provided with notches extending in the same direction, the lower end surface is closed, and the two extending ends are opened so that the object 40 to be detected can enter and exit the groove; the mounting platform is also provided with a guide rail 21 extending in the same direction as the loading groove 12, the guide rail 21 is provided with a pulley block 22 matched with the guide rail, and a wheel carrier 23 of the pulley block 22 is provided with an extension arm 24; the lower end of the extension arm 24 is fixedly connected with the wheel carrier 23, the other end of the extension arm extends upwards to the upper part of the notch of the carrying groove 12, and a distance sensor 31 is arranged above the notch; the measuring direction of the distance sensor 31 passes through the notch to vertically and downwards and is electrically connected with an upper computer arranged outside.

The lower end surface of the carrying groove 12 is concave downwards. The guide rail 21 is a triangular guide rail protruding upwards; the pulley block 22 is matched with the bulge and keeps a height difference with the installation plane. The guide rail 21 is located below the loading chute 12.

A food inspection instrument theory of operation as follows: the object 40 is inserted into the slot from the end of the loading slot 12, and the wheel frame 23 is manually slid so that the distance sensor 31 is carried by the wheel frame 23 and slid from the loading slot 12. The sliding trajectory crosses both the head and tail ends of the object 40. The distance sensor 31 may be an infrared detection or a laser detection, and any one of the distance sensors in the prior art may be used. The distance information received by the distance sensor 31 is initially the distance D1 between the distance sensor 31 and the lower end surface of the loading chute 12, and when the object 40 is slid, the distance becomes shorter. The received distance information is the distance D2 between the upper surface of the object 40 and the distance sensor 31. The diameter D of the sample 40 at the sampling site is known to those skilled in the art from the common general knowledge D1-D2. And the upper computer receives the distance information of the distance sensor 31 and stores the information for subsequent programs. As the distance sensor 31 continues to scan, the distance information returns to the same value as D1, indicating that the distance sensor 31 has completely swept and moved away from above the object 40, completing a diameter sample. According to the common knowledge and the working principle of various existing distance sensors, a person skilled in the art can obtain a large number of diameter samples by one sliding scan, and the specific sampling quantity is controllable and adjustable without additional software improvement.

In order to obtain the length information of the object 40 in one scan, the present invention has at least two embodiments: firstly, a ruler 33 extending in the same direction is arranged on the surface of the guide rail 21. And secondly, an angle sensor 32 is arranged on a bearing of the pulley block 22, and the angle sensor 32 is electrically connected with an upper computer of the peripheral equipment.

The measurement is performed with the angle sensor 32: when the wheel frame 23 slides, the pulley block 22 will rotate together with the rotating shaft, and the rotation of the rotating shaft will be fed back to the angle sensor 32. The diameter of the pulley block 22 is measurable and constant, so that the upper computer can collect the horizontal position of the pulley block 22 at any time according to a known geometric formula. The horizontal stroke of the pulley block 22 corresponding to the diameter change, that is, the length L of the object 40 can be known by combining the diameter sampling change fed back by the distance sensor 31.
