Abstract
The utility model relates to a protective device for strip breakage and strip clamping of a band sawing machine saw blade. The protective device comprises a PLC, a saw frame and a driven wheel and is characterized in that the PLC is connected with a sensor which is installed on the saw frame to detect the change of the revolving speed of the driven wheel. The protective device for strip breakage and strip clamping of the band sawing machine saw blade can automatically detect strip breakage or strip clamping in time and enables a sawing machine to be stopped in time when strip breakage or strip clamping occurs in the running process of the sawing machine, therefore, the service life of the saw blade is prolonged, and production safety is improved.
Description
Technical field
The utility model relates to a kind of band saw machine, particularly a kind of saw blade of band saw broken belt cassette tape protective device.
Background technology
Band sawing machine is a kind of sawing device that uses the metallic decoration wire cutting metal material.Main driving wheel and being arranged on saw frame by the main transmission wheel seat with from the transmission wheel seat respectively from drive wherein, and the drive center of usually all unrolling on above-mentioned two drives is respectively equipped with some annular material reducing through holes, metallic decoration wire drives revolution and metal material is carried out to sawing by main driving wheel with from drive.In actual sawing process, because some material is harder, or the hardness difference, make the saw blade on the normal tape sawing machine easily cause cassette tape, and can produce when serious saw blade stuck, draw the problems such as tooth or broken belt.
Summary of the invention
The utility model, mainly for incident saw blade broken belt cassette tape problem on above-mentioned normal tape sawing machine, provides a kind of saw blade of band saw broken belt cassette tape protective device, while making band sawing machine generation saw blade broken belt or cassette tape, can automatically detect in time and autostop.
A kind of saw blade of band saw broken belt cassette tape protective device described in the utility model comprises PLC controller, saw frame and, from drive, it is characterized in that: described PLC controller be arranged on saw frame on detect and be connected from the sensor of drive rotation speed change.
Described sensor is the photoelectricity approach switch, and stretch out from saw frame the detection termination on this photoelectricity approach switch right side, and relative with annular material reducing through hole from drive.
Operation principle of the present utility model is: when saw blade of band saw, in sawing process, cassette tape or broken belt occur; from the drive rotating speed, will reduce or stop; sensor detects from the drive rotation speed change and sends signal and is sent to the PLC controller, and the PLC controller is just controlled the lathe shutdown after receiving signal in time.
Useful technique effect of the present utility model is: while in the band sawing machine running, cassette tape or broken belt occurring, the utility model can detect and autostop in time automatically, improves blade life, strengthens production safety.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is from the planar structure schematic diagram of drive in Fig. 1.
The specific embodiment
Accompanying drawing marking explanation: sensor 1, material reducing through hole 2, from drive 3, saw frame 4, PLC controller 5, from transmission wheel seat 6.
As depicted in figs. 1 and 2, a kind of saw blade broken belt cassette tape protective device, comprise PLC controller 5, saw frame 4 and from drive 3, described PLC controller 5 be arranged on saw frame 4 on detect and be connected from the sensor 1 of drive rotation speed change.
Described sensor is preferably the photoelectricity approach switch, and stretch out from saw frame the detection termination on this photoelectricity approach switch right side, and relative with annular material reducing through hole from drive.
During the utility model application, at first in the PLC controller, set broken belt cassette tape reference value detection time, and the detection termination on photoelectricity approach switch right side is stretched out from saw frame, and relative with annular material reducing through hole from drive.In the sawing machine running; when the time of passing through between annular material reducing through hole from drive surpasses the setting-up time value; the detected signal of photoelectricity approach switch just will be sent to the PLC controller, and the PLC controller is just made stoppage protection work after receiving signal at once.So just can be when saw blade cassette tape or broken belt timely autostop.
The utility model is by the mode combined between PLC controller, sensor (approach switch) and saw wheel; make sawing machine in running; when saw blade cassette tape or broken belt, can automatically detect timely and autostop; effectively improved the service life of saw blade; promote the sawing machine overall performance, strengthen production safety.
Should be understood that: above-described embodiment is just to explanation of the present utility model, and any innovation and creation that do not exceed in the utility model connotation scope, within all falling into protection domain of the present utility model.
Claims (2)
1. a saw blade of band saw broken belt cassette tape protective device comprises PLC controller, saw frame and, from drive, it is characterized in that: described PLC controller be arranged on saw frame on detect and be connected from the sensor of drive rotation speed change.
2. a kind of saw blade of band saw broken belt cassette tape protective device according to claim 1; it is characterized in that: described sensor is the photoelectricity approach switch; stretch out from saw frame the detection termination on this photoelectricity approach switch right side, and relative with annular material reducing through hole from drive.
