The following describes the material detection device with reference to specific embodiments to further understand the concept of the material detection device.
Referring to fig. 1, in an embodiment, a material detecting device 10 is disposed in a microwave drying apparatus, and includes: the device comprises a detection switch 100, a detection block 110, a sensing block 120, a guide sliding assembly 130 and an elastic element 140, wherein the detection block is arranged at one end of the guide sliding assembly, and the sensing block is arranged at the other end of the guide sliding assembly; the elastic part is positioned between the detection block and the induction part and sleeved on the guide sliding assembly, and the detection switch is arranged close to the detection block.
Specifically, referring to fig. 2, the guide sliding assembly 130 includes a guide shaft 131, a guide sleeve 132, a guide bearing 133, and a bearing mounting seat 134. The guide bearing is embedded into the bearing mounting seat and fixed; the guide shaft is embedded into the inner ring of the guide bearing, and two ends of the guide shaft protrude out of the guide bearing, in one embodiment, in order to facilitate installation, two ends of the guide shaft can be provided with external threads which can be in threaded connection with the two ends of the guide shaft; and fixing the bearing mounting seat. The elastic member 140 is a compression spring, which is sleeved from one end of the guide shaft and one side of which is in contact with the guide bearing; the guide sleeve is also sleeved on the guide shaft from one end close to the compression spring, and one surface of the guide sleeve is in contact with the other surface of the compression spring. The sensing block 120 is fixedly connected with the end part of the guide shaft close to one side of the guide sleeve, and one side close to the guide sleeve is contacted with the guide sleeve. The detection block is fixed at the other end of the guide shaft, namely at one end close to the bearing mounting seat. The detection switch is arranged close to the detection block. In one embodiment, a connecting member 150 may be disposed between the guide shaft and the sensing block, and the connecting member is made of a metal material, and has one surface fixedly connected to the end of the guide shaft and the other surface fixedly connected to the sensing block. Therefore, the induction block can be quickly replaced after being worn; the sensing block matched with the material to be detected can be quickly replaced according to the material or the characteristics of the material to be detected.
It should be noted that the sensing block may be made of a polyurethane material or coated with a polyurethane material. If the material is a product which is easy to scratch and is fragile, the soft material is adopted to play a role in buffering, so that the service life of the detection device is prolonged, and the material can be prevented from being damaged; and can also increase strength when used in conjunction with the connector 150.
The specific working process is as follows: when the induction block at one end of the guide shaft is pushed by a material, the guide shaft and the detection block fixed at the other end of the guide shaft run in the guide bearing along the material running direction under the pushing force, the compression spring between the guide sleeve and the bearing can be extruded, and when the detection block is detected by the detection switch, the material is indicated to run in place, and the follow-up work can be carried out. When the material leaves (is taken out of) the sensing block, the rebound force of the compression spring acts on the guide sleeve, and the guide sleeve acts on the guide shaft, so that the sensing block returns to the original position. On one hand, the whole process can realize non-contact detection of materials, and reduce the hidden danger of damage and service life of a detection switch; on one hand, the automatic reset of the induction block can be realized, the detection efficiency is improved, the structure is simplified, the cost is low, and the maintenance is easy.

The material detection device 10 is fixedly arranged on the side surface of the sealed cavity body opposite to the furnace door. Specifically, bearing fixing base fixed mounting is in seal chamber's side to the one end of installation response piece is located seal chamber, and the one end of installation detection piece is located outside seal chamber. One end of the bracket 70 is fixedly arranged on the furnace body frame, and the other end is fixed with the detection switch. It should be noted that, the bearing fixing seat and the seal cavity can adopt a welding mode, and the installation surfaces are sealed. The guide shaft, the bearing and the guide bearing are connected in a matched mode, seamless butt joint of the material detection device and the sealing cavity is achieved, and potential safety hazards and environmental pollution caused by microwave leakage are avoided.
When the device works, the conveying roller way 50 conveys the materials 80 placed on the conveying roller way from the outside of the furnace door to the inside of the sealed cavity, the surface of one side, away from the furnace door, of the materials firstly contacts with the induction block of the material detection device after the materials run for a certain distance, under the conveying power provided by the conveying roller way, the induction block, the guide shaft, the guide sleeve and the detection block simultaneously run in the direction away from the furnace door under the guide of the guide bearing, and at the moment, the compression spring is in a compression state under the running of the guide sleeve. After one end of the conveyor runs for a distance, the detection block touches the detection switch, so that the detection switch sends a signal, the conveyor roller stops acting at the moment, and the material is dried or starts to act next step. When the materials are dried or other processes are finished, the conveying roller way reversely runs and leaves the microwave drying equipment, the rebounding force of the compression spring can eject the guide sleeve out towards the direction of the oven door, the guide sleeve acts on the induction block, and the induction block is fixedly connected with the guide shaft, so that the guide shaft also runs towards the direction of the oven door until the compression spring is restored to be uncompressed. At the moment, the detection switch resets, the induction block also resets, and the next detection is waited. Thus repeating.
The invention reduces the cost and difficulty of automatic material detection and realizes the automation of microwave drying by the cooperation of the transmission of the mechanical structure and the detection switch. The detection switch and the detection block are arranged outside the sealed cavity body and are far away from microwaves during working, so that the service life of the material detection is prolonged. And because the detection switch is installed in setting up the outside, operating personnel can direct observation to detect the state of switch, can not influence the maintenance change or maintenance detection switch under the normal operating condition of equipment again. The direct contact of response piece and material improves the stability and the degree of accuracy that detect, detects switch and material non-direct contact in addition, realizes detecting through intermediate device, and the theory and the mode that this kind of non-contact detected have spreading value and reference meaning under the operating mode that is not suitable for the direct contact to detect.
Further, in order to prevent the material detection device from being out of order or becoming invalid during operation, the microwave drying equipment further comprises a limiting component 60. The limiting assembly 60 is arranged on one side of the conveying roller way, which is far away from the furnace door, and is arranged in parallel with the material limiting assembly, so that mechanical safety protection is provided. When the material detection device is invalid, the limiting assembly can prevent the conveying roller way from continuously operating to cause damage to materials or mechanical structures.
