Embodiment Construction

[0024] The belt slip detection device provided by the present invention is used to detect the belt slip condition of the belt conveyor, and can be processed in time, which not only prolongs the service life of the belt, reduces the downtime rate of the equipment, but also enables the production process line to proceed smoothly and improve Increased production efficiency.

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0026] See attached figure 1 And figure 2 , Is a schematic struct...

Abstract

The invention discloses a belt slip detecting device comprising a frequency converter, an incremental rotary encoder and a microcontroller, wherein the frequency converter is connected with a belt conveyor and is used for controlling the rotation speed of a driven roll of the belt conveyor; the incremental rotary encoder is arranged on the driven roll and is used for detecting an actual speed value of a belt; the microcontroller is connected with the incremental rotary encoder and the frequency converter and is used for comparing a difference value of the actual speed value and a predetermined speed value of the frequency converter with a predetermined slip value range and controlling the frequency converter to execute the speed changing operation of the driven roll according to a comparing result; when the difference value is greater than the maximum value within a slip value range, the microcontroller controls the frequency converter to execute operation for accelerating the rotation speed of the driven roll; and when the difference value is smaller than the maximum value within the slip value range, the microcontroller controls the frequency converter to execute the operation for slowing the rotation speed of the driven roll.

Description

Technical field [0001] The invention relates to the technical field of belt conveyors, and more specifically to a belt slip detection device. Background technique [0002] Medium-density fiberboard is a product developed in the mid-1960s. In recent years, the output has developed rapidly. The reason is that it has excellent physical and mechanical properties, decorative properties and processing properties. It has gradually become one of the mainstream products in this field. [0003] In the current MDF production line, there is no belt slip detection device, so when belt slip occurs, it cannot be detected in time. The difference between the actual speed of the belt and the preset speed is the slip value. When the slip value exceeds the preset slip value, it will cause damage to the belt, reduce the service life of the belt, and may also cause damage to the production equipment, and It will inevitably affect the continuity of the entire MDF production line and the product quality ...
