Detailed description of the invention
Fig. 1 is a kind of use state structure of belt feeder tensile force decline protective device described in the utility model embodiment Schematic diagram;
Fig. 2 is enlarged diagram at A in Fig. 1;
Fig. 3 is enlarged diagram at B in Fig. 1.
Specific embodiment
For convenient for those skilled in the art understand that technical solutions of the utility model, practical new to this now in conjunction with Figure of description Type technical solution is described further.
Fig. 1 show the structure that the decline of belt feeder tensile force described in the present embodiment protective device is installed on belt feeder and shows It is intended to, the direction of arrow is belt tension direction in figure, and following front ends is arrow direction, and rear end is its opposite direction.
Refering to fig. 1, the belt feeder includes track 1, and the track 1 is equipped with tensioning sports car 2, the tensioning sports car 2 Rear end is equipped with storage cassette holder 3, and part belt 4 is located in storage cassette holder 3, stores up and is additionally provided with support frame 5 at cassette holder 3.
The belt feeder tensile force decline protective device includes on off controller (not shown), the first sensing device 6 and second sensing device 7.
The on off controller is shut down to control belt feeder.On off controller in the present embodiment is what belt feeder carried Emergency stop protection device (not shown).
As shown in Fig. 2, first sensing device 6 includes the first fixed frame 61 and the first inductor 62, first fixation Frame 61 is L-shaped, including horizontal fixed plate 611 and horizontal mounting plate 612, and the horizontal fixed plate 611 is fixedly arranged on tensioning sports car 2 The side of rear end track 1;First inductor 62 described in the present embodiment is first stroke switch, and first stroke switch is set It is placed in the upper end of horizontal mounting plate 612, and is not less than the lower edge in 2 compartment of tensioning sports car, so as to the sport car 2 that is tensioned It collides and is closed.Preferably, the first sensing device 6 is apart from 5 rear end 0.5m of tensioning sports car when belt tension.
As shown in figure 3, second sensing device 7 includes the second fixed frame 71 and the second inductor 72, described second is solid Determining frame 71 is horizontal gird, is fixedly arranged on support frame 5, and is located at the lower section of storage 3 inner belt 4 of cassette holder.Second inductor 72 for second stroke switch, setting with the second fixed frame 71 close to one end of tensioning sports car 2, and the second stroke switch with Horizontal plane is in an angle, so as to collide and be closed in the sag of belt.
