Abstract
The utility model discloses a speed detector of a belt conveyor. The speed detector comprises a driven roller shaft (1), wherein a dial (2) arranged on the driven roller shaft (1), four convex blocks (3) are uniformly distributed on the dial (2), a detection switch (4) is fixed on the side plate of the belt conveyor, the distance between the inductive head of the detection switch (4) and the convex blocks (3) is 8-10mm, and the detection switch (4) is connected with a PLC (Programmable Logic Controller) input point by virtue of a wire. The speed detector can be used for solving the problems that the existing speed detector uses an encoder to detect, which leads to complicated structure and high cost, and the prior speed detector uses a belt drilling way to detect, which leads to reduction in the belt strength and the service life.
Description
Technical field
The utility model relates to band conveyor speed detection technique field.
Background technology
Band conveyor extensively uses in logistics field; The travelling speed that velocity test adopts scrambler usually or boring detects belt feeder through the mode in detector switch detection hole on belt feeder about band conveyor; But these two kinds of modes are all not enough to some extent, adopt coder structure complicated and with high costs, adopt belt feeder to hole through the detector switch detection mode owing to need on belt feeder, hole; Can cause the intensity and the life-span of belt to be reduced, influence the serviceable life of complete machine.
Summary of the invention
The technical matters that the utility model will solve: a kind of band conveyor speed measuring device is provided
With the velocity test that solves band conveyor adopt the scrambler test cause complex structure with high costs with adopt the belt borehole test can cause belt intensity and life-span to reduce the problems such as serviceable life that consequently influence complete machine.
The utility model technical scheme:
A kind of band conveyor speed measuring device; It comprises driven drum shaft; Code-disc is installed on the driven drum shaft, and code-disc has 4 equally distributed projections, and detector switch is fixed on the band conveyor side plate; The inductive head of detector switch is the 8-10 millimeter to the projection distance, and detector switch is wired to PLC controller input point.
The beneficial effect of the utility model:
The utility model is compared with existing band conveyor velocity measuring technique; Have simple in structure; Characteristics such as with low cost; The speed that can be widely used in band conveyor tests the speed, and does not injure the serviceable life that the belt integral surface has improved belt, the velocity test that the utility model has solved band conveyor adopt the scrambler test cause complex structure with high costs with adopt the belt borehole test can cause problems such as belt intensity and life-span reduction.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
A kind of band conveyor speed measuring device (Fig. 1), code-disc (2) are installed on the driven drum shaft 1 of band conveyor, and code-disc (2) adopts interference fit with driven drum shaft (1); Code-disc 2 has 4 equally distributed projections 3; Detector switch 4 is fixed on the band conveyor side plate, and detector switch 4 adopts near switch, detects distance and selects 12 millimeters; The inductive head of detector switch 4 is the 8-10 millimeter to projection 3 distances; Detector switch 4 is wired to PLC controller input point, and when band conveyor moved, the projection 3 that driven drum shaft 1 rotation drives on the code-disc (2) rotated together; The signal feedback that detects projections 3 through detector switch 4 can draw the travelling speed of band conveyor to the PLC controller.
Claims (1)
