Detailed Description

The technical scheme of the invention is further explained by combining the attached drawings in the embodiment of the invention.

An automatic tightening belt shearing device comprises a mounting plate 1, a pneumatic motor 2, a belt sleeving device 3, a belt shearing cylinder 7 and a knife switch 5,

an open slot 101 is arranged in the middle of the mounting plate 1,

the pneumatic motor 2 and the tape shearing cylinder 7 are mounted on the mounting plate 1, the tape sleeving device 3 is mounted on a rotary output shaft of the pneumatic motor 2, and the knife switch 5 is mounted at the rod end of the tape shearing cylinder 7.

As shown in fig. 1, 2 and 5, the binding band 13 and the bag which need to be tightened and cut are positioned at the rear side of the mounting plate 1, the binding band 13 is provided with a band buckle 12, the binding band 13 is penetrated from an open slot 101 and wound on the bagging device 3, and the binding band 13 is tightened under the rotation action of the pneumatic motor 2, and the band buckle 12 is also positioned at the rear side of the mounting plate 1. The rod end of the tape cutting cylinder 7 extends out, and the band 13 is cut off by the knife switch 5. In the whole process, other work contents except the strap sleeving and the ribbon taking-down 13 are automatically completed, so that the labor intensity is reduced.

In the process of tightening the binding tape, the tightness of the binding tape 13 is not well controlled, and the stop time of the pneumatic motor 2 is difficult to select. If too loose, the tie 13 cannot tighten the bag and the tightening quality cannot be guaranteed. If the band is too tight, the band 13 may be pulled off directly, which may result in the band being unusable.

For this reason, automatic lacing tape-shearing device, still include guiding axle 8, compression spring 9, travel switch 10 and limiting plate 11, 8 one end of guiding axle is connected with mounting panel 1, and the other end is connected with limiting plate 11, compression spring 9 suit is on guiding axle 8, set up first open slot 111 corresponding with open slot 101 on the limiting plate 11, travel switch 10 installs on mounting panel 1.

As shown in fig. 2, the strap 13 passes through the open slot 101 and the first open slot 111, and is sleeved on the strap sleeving device 3, the bag buckle 12 is clamped outside the limit plate 11, in the process of rotating and tightening the strap 13 by the pneumatic motor 2, the strap 13, the strap buckle 12 and the limit plate 11 are pulled to move rightwards on the guide shaft 8, in the moving process, the limit plate 11 triggers the travel switch 10, and when the travel switch 10 receives a signal, the control device, such as a PLC controls the pneumatic motor 2 to stop rotating, and then performs a cutting operation. The stop time of the starting motor 2 is determined by the travel switch 10, and the binding belt 13 is effectively prevented from being too loose or too tight. The degree of tightness after tightening of the band 13 can be adjusted by moving the position of the travel switch 10.

As shown in fig. 7, the taping device 3 includes a disk 35 and two cylinders 36, a central hole adapted to the output shaft of the pneumatic motor 2 is formed in the middle of the disk 35, and one end of each of the two cylinders 36 is fixedly connected to the disk 35.

In the figure, the strap attaching means 3 is mounted on the output shaft of the pneumatic motor 2, and the strap 13 is attached to one of the cylinders 36, at which time the pneumatic motor 2 is rotated to wind the strap 13 around the cylinder 36 and tighten it.

Although the strap sleeving device 3 in fig. 7 is simple and practical, and is very convenient for strap sleeving and strap taking, in the actual use process, the strap 13 is easy to fall off, and another strap sleeving device 3 is designed for solving the problem, as shown in fig. 3, the strap sleeving device 3 comprises a first strap disc 31, a second strap disc 32 and a strap sleeving rod 33, the middle of the first strap disc 31 and the middle of the second strap disc 32 are provided with central holes matched with the rotating output shaft of the pneumatic motor 2, one end of the strap sleeving rod 33 is fixedly connected with the second strap disc 32, and the first strap disc 31 is provided with a through hole 34 matched with the strap sleeving rod 33.

In the drawing, a first strap disk 31 and a second strap disk 32 are detachably mounted on an output shaft of the pneumatic motor 2, and when the strap is applied, the first strap disk 31 is first mounted on the starting motor 2, the strap 13 is sleeved on the strap rod 33, the second strap disk 32 is moved close to the first strap disk 31, and the strap rod 33 is inserted into the through hole 34. At this time, the pneumatic motor 2 is started to rotate the first strap disk 31 and the second strap disk 32, and the strap 13 is tightened. The falling off of the binding belt 13 is effectively prevented. After the binding belt 13 is tightly cut, the second binding belt disk 32 can be conveniently taken down, and the binding belt 13 is conveniently taken down.

In the process of using the strap device 3 of fig. 3, there is a new problem that the second strap disk 32 is easy to slide to the left during the rotation of the pneumatic motor 2, and the strap bar 33 is slid out of the through hole 34, which causes the strap 13 to be released.

Therefore, the automatic tightening belt shearing device further comprises an anti-tripping device 6, the anti-tripping device 6 comprises a rotating support 61, a rotating handle 62 and a nylon cushion block 63, the rotating support 61 is fixedly arranged on the mounting plate 1, the upper end of the rotating handle 62 is rotatably connected with the rotating support 61, and the nylon cushion block 63 is arranged in the middle of the rotating handle 62.

As shown in fig. 3, after the taping is completed, the rotating handle 62 is rotated down, and the nylon cushion block 63 is rotated to the left position of the second taping disk 32 to abut against the nylon cushion block, so as to play a role in limiting, and prevent the second taping disk 32 from moving leftwards in the rotating process.

To prevent the rotational friction of the second strap disk 32 from rotating the rotary handle 62 back during rotation of the air motor 2, the rotary handle 62 is rotated back opposite to the rotary direction of the air motor 2, as shown in fig. 4, so that the rotary handle 62 is not rotated back during rotation of the air motor 2.

Fig. 8 is a front view and a top view of the blade 5.
