Fig. 10 is a schematic diagram of a detection mechanism in an embodiment of the present invention in an abrasive belt deflection adjusting apparatus. Fig. 11 is a schematic structural view of an optoelectronic switch in the device for adjusting belt deflection according to an embodiment of the present invention.
As shown in fig. 10-11, a detection mechanism 70, disposed above the belt between the main drum and the tensioning drum, comprises: four groove-shaped photoelectric switches 71 and a photoelectric switch support bracket 72.
The opto-electronic switch support bracket 72 has a U-shaped slot for receiving the slotted opto-electronic switch 71. The optoelectronic switch support bracket 72 has four openings at the top.
In the present embodiment, the four groove-type photoelectric switches 71 have the same structure but different functions. Each of the groove-type photoelectric switches 71 includes a photoelectric box 711, a photoelectric box hanger plate 712, and a photoelectric box hanger 713.
The photoelectric box 711 includes a left side arm 711a, a right side arm 711b, and a suspension arm 711 c.
The left arm 711a is provided with a light emitter, which is an infrared emitter in this embodiment. The right arm 711b is provided with a light receptor, which in this embodiment is an infrared receiving tube for receiving light emitted from the infrared emitting tube. The side of the right arm 711b to which the infrared receiver tube is attached is disposed opposite to the side of the left arm 711a to which the infrared emitter tube is attached. Boom 711c is used to connect left side arm 711a and right side arm 711b to form a U-shaped slot through which belt 30 passes.
A photovoltaic box hanger plate 712 is mounted on top of the photovoltaic box 711. The photoelectric box suspension bar 713 is inserted into an opening at the top of the photoelectric switch support frame 72 and is screwed with the photoelectric switch support frame 72. The bottom of the photovoltaic box hanger 713 is fixedly connected to the photovoltaic box hanger plate 712. The user can adjust the height of the photovoltaic box 711 by adjusting the photovoltaic box hanger 713.
The four groove-shaped photoelectric switches 71 have different heights from the upper edge of the abrasive belt 30. In the present embodiment, hereinafter, for convenience of description, the four groove-type photoelectric switches 71 are referred to as a first photoelectric switch 71a, a second photoelectric switch 71b, a third photoelectric switch 71c, and a fourth photoelectric switch 71d, respectively. The detection positions of the first photoelectric switch 71a, the second photoelectric switch 71b, the third photoelectric switch 71c, and the fourth photoelectric switch 71d correspond to the respective offset positions. Specifically, when the first photoelectric switch 71a detects that the upward deviation position of the abrasive belt 30 is equal to or higher than the upper limit alarm position, a stop signal is issued to the control unit. When the second photoelectric switch 71b detects that the offset position of the abrasive belt 30 is higher than the downstream return position, a downstream signal is sent to the control unit. When the third opto-electronic switch 71c detects that the offset position of the abrasive belt 30 is below the up-going return position, an up-going signal is sent to the control unit. When the fourth photoelectric switch 71d detects that the downward offset position of the abrasive belt 30 is lower than or equal to the lower limit alarm position, a stop signal is sent to the control unit.
The control unit is used for controlling the deflection mechanism 10 for adjusting the sanding belt 30 and for controlling the tensioning mechanism 50 for adjusting the distance between the tensioning roller 20 and the main roller 10. In this embodiment, the control unit is a programmable logic controller (i.e., PLC). Specifically, in the present embodiment, the programmable logic controller controls the operation of each driving mechanism by adjusting the switch of the electromagnetic valve, so as to realize the corresponding function. In this embodiment, the control units of the deviation adjusting mechanism 10 and the tensioning mechanism 50 are the same programmable logic controller, and in other embodiments, the control units of the deviation adjusting mechanism 10 and the tensioning mechanism 50 may be two independent programmable logic controllers.
The working principle of the deviation adjusting mechanism of the abrasive belt deviation adjusting device provided by the embodiment is as follows:
when the first photoelectric switch 31a detects that the upward deviation amount of the abrasive belt 30 is greater than or equal to the upper limit alarm value, a stop signal is sent to the control unit. When the fourth photoelectric switch 31d detects that the downward deviation amount of the abrasive belt 30 is greater than or equal to the lower limit alarm value, a stop signal is sent to the control unit. When the control unit receives the stop signal, the control unit controls the driving member of the main roller 10 to stop running through the electromagnetic valve.
When the second photoelectric switch 31b detects that the upward offset of the abrasive belt 30 is greater than the downward return value, it sends a downward signal to the control unit. When the third opto-electronic switch 31c detects that the amount of downward displacement of the abrasive belt 30 is larger than the up-return value, an up-signal is sent to the control unit.
When the control unit receives the uplink signal or the downlink signal, the control unit controls the offset driving member 48 through the electromagnetic valve to drive the first oscillating bar 44 to move around the offset rotating shaft 42, so as to drive the second oscillating bar 47 to swing, and the second oscillating bar 47 drives the tensioning roller 20 and the second oscillating bar 47 to swing synchronously through the offset rotating shaft, so that the axis of the tensioning roller 20 and the axis of the main roller 10 form a certain included angle. The deflection of the sanding belt 30 is achieved when the axis of the tensioning roller 20 is at an angle to the axis of the main roller 10. Taking fig. 2 as an example, when the sanding belt rotates clockwise, the downward deviation of sanding belt 30 can be realized by controlling tensioning roller 20 to swing upward in the figure, and the upward deviation of sanding belt 30 can be realized by controlling tensioning roller 20 to swing downward in the figure. And vice versa.
The working principle of the tensioning mechanism of the belt deflection adjusting device provided by the embodiment is as follows:
when tensioning of the sanding belt 30 is required, a tensioning command is issued in the control unit, which controls the upper tensioning cylinder 51 and the lower tensioning cylinder 54 to run synchronously by means of the solenoid valve. The upper tensioning cylinder 51 pushes the deflection shoe 41 away from the main cylinder 10 to bring the tensioning cylinder 20 away from the main cylinder 10. The lower tension cylinder 54 moves the tension roller 20 away from the main roller 10 by a reaction force generated by pushing the partition 15. When the distance between the tensioning roller 20 and the main roller 10 increases, the tensioning of the sanding belt 30 is achieved.
When the sanding belt 30 needs to be loosened, the tensioning roller 20 needs to be manually pushed towards the main roller 10.
The operating principle of the speed regulating mechanism of the abrasive belt deflection regulating device provided by the embodiment is as follows:
the speed regulating slider 62 is moved along the length direction of the speed regulating screw 64 by manually rotating the speed regulating screw 64, thereby changing the swing range of the first swing link 44. When the swing amplitude of the first swing link 44 is larger, the speed of the first swing link driving the abrasive belt 30 to go up or down is higher. And vice versa.
