Abstract
The utility model relates to a mechanical belt automatic rectification device, which comprises a mechanical guide clamp tracking the belt position at the two sides of the front end, namely, the belt entering end; the distance of two guide clamps is the same with the belt width; the guide clamp is arranged on two extension arms being parallel to the operation direction of the belt; the extension arm is directly arranged on a roller seat which is arranged at the center of a large bracket by a ball bearing in beeline motion; the large bracket is provided with a displacement sensor for detecting the belt position; a telescopic rod of the sensor is connected with the guide clamp. The utility model has the advantages that the guide clamp can suitably change the position with the deflection of the belt; the change of the position of the guide clamp leads the axis line of the rectification roller and the belt operation direction to form a non-vertical angle which has proportional relationship with the change quantity of the position of the guide clamp; the contact pressure between the rectification roller and the belt is decomposed into a rectification force in proportion with the angle by the non-vertical angle of the axis line of the roller; the utility model is an ideal belt automatic rectification device which can not be assimilated by an electric rectification device.
Description
Technical field
The utility model relates to a kind of deviation correcting device, is a kind of band conveyor that can be loaded on multiple industry, the automatic tracking on the belt conveyer scale, proofreaies and correct belt and make the device that it can not sideslip.
Background technology
The deviation correcting device of prior art is electrodynamic type mostly, place correction cylinder on the belt by an electric pushrod push-and-pull, make cylinder axis and belt direction of travel form non-perpendicular angle and produce correction power, the action of motorized pulleys by be installed on belt can sideslip photoelectric switch or other type of switch of end position provide signal, realize control.Because the on-off signal of belt both sides can only provide the signal of two end positions, the scaling signal relevant with the belt deviation state can not be provided, the action of electric pushrod can only be several states of presetting, certainly will cause correction power and sideslip force unbalance, cause the sideslip vibration of the belt left and right sides, form unsure state, influence the life-span of belt and deviation correcting device, if be installed on metering outfits such as belt conveyer scale, will influence the metering performance of equipment.
Summary of the invention
The purpose of this utility model is to overcome the prior art deficiency, and a kind of reliable, stable, mechanical type automatic deviation-correcting device for belt that cost is low is provided.
The utility model is achieved through the following technical solutions: the machinery of following the tracks of belt position is installed in the both sides of belt upstream end leads folder, two distances of leading folder are identical with belt width, leading folder is installed on two extension arms parallel with belt direction of travel, the extension arm direct mount is in roller seat, roller seat is installed on big carriage center by ball bushing, roller seat can be by ball bushing rotation and up-and-down movement on big support, on the big support displacement pickup that detects belt position is installed, the expansion link of sensor connects with leading folder, produces corresponding stroke along with the sideslip of belt.
Principle of work: lead folder and change the position with belt deviation in good time, the change of leading the folder position makes correction cylinder axis and belt direction of travel form non-perpendicular angle, the angle of non-perpendicular angle is measured proportional relation with the change of leading the folder position, and the contact pressure of correction cylinder and belt is because decomposition of non-perpendicular angle and the proportional correction power of angle.Described correction roller seat links to each other with big support by ball bushing, rotatablely moving of ball bushing guaranteed to lead the alerting ability that folder is followed the tracks of belt position, straight-line motion has guaranteed that the correction cylinder follows the tracks of the elongation and the contraction of belt in good time neatly, keep cylinder and the constant contact force of belt, thereby guaranteed the formation of a certain proportion of correction power, realized stepless correction.Displacement pickup output and the proportional analog signals of belt deviation amount are used for monitoring and control.
The utility model compared with prior art has following advantage and effect: do not need carrying roller correction motor and reversing switch, the malfunctioning belt that will directly cause of these elements damages, because the correction power of mechanical type correction cylinder and the proportional relation of displacement of belt deviation, realized the dynamical equilibrium of correction power and belt deviation power, avoid operating repeat runs polarization to swing, helped the accurate metering of belt smooth operation and belt conveyer scale.The utlity model has simple, reliable, correction power is strong, can the continous-stable correction, characteristics with low cost, this is that electronic correction is incomparable.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the utility model structural representation;
Fig. 2 is the cutaway view of the utility model correction roller seat, ball bushing and support among Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, among the figure, 1 leads folder for belt machinery, and two of symmetries are sandwiched in the belt both sides respectively, lead ball roller flexibly is housed in the folder, can form with belt side and roll, and guarantee that belt does not does not wear and tear; 2 is displacement pickup, and sensor base and support fixation thereof are in big support 3, and big support 3 is installed on the frame of band conveyor, and 4 are correction cylinder and roller seat, and 5 is ball bushing, and the outer ring is fixed on the big support 3, and 6 is turning cylinder.Belt machinery is led folder 1, correction cylinder and roller seat 4, turning cylinder 6 is linked to be a general frame by machinery, this framework hangs on big support 3 by ball bushing 5, the sideslip motion of belt drives leads folder 1, thereby drive the small frame that belt machinery is led folder 1, correction cylinder and roller seat 4, turning cylinder 6 formation, rotate by ball bushing 5 and big support 3.Rotatablely move and make the axis and the belt direction of travel of correction cylinder 4 produce non-perpendicular angle, because whole small frame can be made straight-line motion up and down by ball bushing 5 and big support 3, the deadweight of this framework makes cylinder follow the tracks of belt flexibly, keep and the constant contact force of belt, guarantee the formation of a certain proportion of correction power, realized the automatic stepless deviation-correcting function.
