The cutting piece can be freely folded up, and the knife can be put away in time when problems occur, which has high safety.

[0027] About the First Drive Unit:

[0028] The first driving part includes a slide groove 7 opened on the front side of the first horizontal plate 2, a first screw rod 8 is arranged in the slide groove 7, the first screw rod 8 is rotatably connected in the slide groove 7, a nut seat is sleeved on the outer side of the first screw rod 8, the nut seat is threadably matched with the first screw rod 8, the nut seat is detachably connected with the first matching block 9, the first matching block 9 is slidably connected with the slide groove 7, a first motor 10 is arranged on the outer side of the first horizontal plate 2, and the output end of the first motor 10 is fixedly connected with the first screw rod 8.

[0029] The first driving part is a common screw transmission mechanism, which drives the first screw 8 to rotate through the first motor 10. The first screw 8 cooperates with the nut seat during rotation, driving the nut seat to move along the rod body of the first screw 8. Since the nut seat is fixed to the first matching block 9, and the first matching block 9 is connected to the lifting bracket, the first matching block 9 will also move with the lifting bracket.

[0030] In order to improve the stability of the lifting bracket when it moves, a guide rail 4 is laid on the front of the second horizontal plate 3, and a slider 5 is provided on the guide rail 4. The slider 5 is slidably connected to the guide rail 4, and the slider 5 is detachably connected to the second matching block 11. When the lifting bracket moves, the second matching block 11 connected to the lower end of the lifting bracket will also slide along the guide rail 4. The guide rail 4 cooperates with the second matching block 11 to limit the second matching block 11 from the lower end of the lifting bracket, so that the cutting piece will not be offset when it moves left and right.

[0031] For the specific structure of the lifting bracket, please refer to the following description.

[0032] The lifting bracket includes a limit rod 13, the upper end and the lower end of the limit rod 13 are fixedly connected to the first matching block 9 and the second matching block 11 respectively, and a positioning seat 14 is sleeved on the outer side of the limit rod 13, the positioning seat 14 is slidably connected to the limit rod 13, and the positioning seat 14 is detachably connected to the cutting piece.

[0033] The second driving member controls the height of the positioning seat 14 . When the positioning seat 14 changes in height, the positioning seat 14 moves along the rod body of the limiting rod 13 . The limiting rod 13 cooperates with the positioning seat 14 to guide the positioning seat 14 .

[0034] The specific structure of the cutting piece is shown in the following description.

[0035] The cutting member includes a mounting seat 15, a width cutter 16 is provided on the side of the mounting seat 15 away from the positioning seat 14, a slot 6 is provided on the side of the mounting seat 15 facing the positioning seat 14, the slot 6 cooperates with the positioning seat 14, and a second fixing bolt 20 is installed on the outside of the mounting seat 15, the second fixing bolt 20 penetrates into the slot 6 and is threadedly connected with the bolt hole provided on the outside of the positioning seat 14. When the cloth passes under the mounting seat 15, the width cutter 16 on the mounting seat 15 will cut the cloth to limit the width. When the mounting seat 15 is removed from the positioning seat 14, the second fixing bolt 20 can be screwed out from the bolt hole on the outside of the positioning seat 14.

[0036] About the second drive unit:

[0037] The second driving part includes a second screw 18, the upper end and the lower end of the second screw 18 are rotatably connected to the first matching block 9 and the second matching block 11 respectively. A second motor 19 is provided at the upper end of the first matching block 9, and the output shaft of the second motor 19 is fixedly connected to the second screw 18. The second screw 18 penetrates the positioning seat 14 and is threadedly connected to the positioning seat 14.

[0038] The second driving member also uses a screw transmission mechanism for height control. When the second motor 19 drives the second screw 18 to rotate, the positioning seat 14 matched with the second screw 18 will move along the rod body of the second screw 18 to adjust the height of the positioning seat 14 and the cutting member.

[0039] Of course, the first driving member and the second driving member may also be replaced by other linear driving mechanisms, which will not be explained in detail here.

[0040] In the preferred solution, the first matching block 9 and the second matching block 11 are both equipped with a first fixing bolt 12 on their outer sides, and threaded holes are provided on the outer sides of the nut seat and the slider 5, and the first fixing bolt 12 is threadedly connected to the threaded holes. The first matching block 9 and the second matching block 11 are fixed to the nut seat and the slider 5 in a detachable connection manner. The advantage of such a design is that when the lifting bracket is completely removed, it is only necessary to release the fixing of the nut seat and the first matching block 9, and the slider 5 and the second matching block 11 bracket.

[0041] In order to prevent dust from falling on the second screw 18 and affecting the cooperation between the second screw 18 and the positioning seat 14, in a preferred solution, an accordion-type cover 17 is provided between the positioning seat 14 and the first matching block 9, and between the positioning seat 14 and the second matching block 11. The accordion-type cover 17 is fixedly connected to the upper end and the lower end of the positioning seat 14, and the end of the accordion-type cover 17 away from the positioning seat 14 is fixed to the first matching block 9 and the second matching block 11. The accordion-type cover 17 can be unfolded and folded following the rise and fall of the positioning seat 14.

[0042] How this application works:

[0043] The first horizontal plate 2 and the second horizontal plate 3 are fixed between the two side plates on the frame 1, and the cloth passes between the two side plates. The lifting bracket can slide along the first horizontal plate 2 and the second horizontal plate 3, and the cutting piece can slide along the lifting bracket. Under the control of the driving member, the left and right position and height of the cutting piece can be adjusted. The width adjustment is flexible, and the cloth width can be adjusted in time. The cutting piece can be freely retracted, and the knife can be retracted in time when a problem occurs, which is highly safe.
