DETAILED DESCRIPTION

[0022] In order to make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. In order to keep the following description of the embodiments of the present disclosure clear and concise, the present disclosure omits detailed descriptions of known functions and known components to avoid unnecessary confusion of the concepts of the present invention.

[0023] See also Figure 1-2 A fixed-distance cutting device for woven bags comprises a discharge chute 1 and two supporting columns 2 installed on the sides of the discharge chute 1, and a conveyor belt 3 for conveying woven bags is arranged between the two supporting columns 2, and a rotatable guide roller 12 is arranged at the front end of the two supporting columns 2, and the woven bags are redirected and introduced into the conveyor belt 3 through the guide roller 12, so that the conveyor belt 3 drives the woven bags to move forward and is introduced into the discharge chute 1, and the woven bags in the discharge chute 1 fall, so that the woven bags are conveyed downward.

[0024] A straight groove 4 for the woven bag to fall is installed at the bottom end of the discharge chute 1, and a truncation groove 5 for cutting the woven bag is installed at the bottom end of the straight groove 4. The straight groove 4 is used to increase the distance of the woven bag discharge and limit the range of movement of the woven bag, so that the woven bag can be guided into the truncation groove 5 for truncation.

[0025] The truncation groove 5 includes a groove body 51, and a vertically symmetrical inclined material guide plate 52 is installed on one side of the inner wall of the groove body 51. A slidable movable seat 53 is provided in the groove body 51 between the two inclined material guide plates 52. The movable seat 53 is pushed by an electric cylinder 58 outside the groove body 51. A telescopic rod 54 and a hot cutting knife 56 are installed on the movable seat 53, and an extrusion plate 55 is installed on the other end of the telescopic rod 54, and a spring for resetting is sleeved on the telescopic rod 54.

[0026] A base 57 is installed on the other side of the inner wall of the trough body 51 , and the squeezing plate 55 presses the woven bag onto the base 57 , while the hot cutter 56 cuts the woven bag on the base 57 , so that the woven bag is pressed and cut onto the woven bag base 57 .

[0027] When the electric cylinder 54 pushes the movable seat 53 to move, the squeezing plate 55 first presses and contacts the woven bag, and presses the woven bag against the base 57 to prevent the woven bag from falling further and position the woven bag. The squeezing plate 55 will block the woven bag, and as the movable seat 53 continues to move, the telescopic rod 54 contracts until the hot cutter 56 contacts the woven bag and cuts it off. Then the electric cylinder 54 drives the movable seat 53 to return to its original position, and the telescopic rod 54 is reset under the action of the spring. When the squeezing plate 55 is separated from the woven bag, the woven bag that falls on the squeezing plate 55 falls quickly and is transported again. During this process, the conveyor belt 3 continues to run to avoid intermittent operation.

[0028] Two connecting columns 6 inclined downward are installed at the bottom of the cutting groove 5, and a plurality of groups of rollers 7 are arranged between the two connecting columns 6. The woven bag is discharged from the cutting groove 5 and falls on the rollers 7, and is discharged downward along the rollers 7. A conveyor 11 for discharging the woven bag is arranged at the bottom ends of the two connecting columns 6, and the conveyor 11 and the conveyor belt 3 are both in a horizontal state. The woven bag discharged from the cutting groove 5 is laid flat on the rollers 7, and slides down the rollers 7 to the conveyor 11 under gravity, and the cut woven bag is discharged through the conveyor 11.

[0029] The groups of rollers 7 between the two connecting columns 6 are densely and evenly distributed, and the spacing between the rollers 7 is 1-2 cm, so as to avoid the spacing between the rollers 7 being too large, causing the woven bag to slip from the spacing between the rollers 7.

[0030] The two connecting columns 6 are each provided with a slidable slider 8, and a connecting beam 9 is installed at the top of the two sliders 8, and a laser sensor 10 for detecting the passage of the woven bag is installed on the connecting beam 9. The position of the laser sensor 10 is adjusted by adjusting the position of the slider 8. When the woven bag passes through the laser sensor 10, the laser sensor 10 is triggered to control the cutting groove 5 to cut the woven bag.

[0031] The device also includes a controller, which detects the state of the laser sensor 10 and can understand that the woven bag passes through the laser sensor 10. When the laser sensor 10 is triggered, the woven bag moves to the bottom of the laser sensor, and the controller drives the cutting groove 5 to quickly cut it off to complete the fixed-distance cutting. The position of the laser sensor can be adjusted by adjusting the movement of the slider, so as to adjust the length of the woven bag cut off by the cutting groove 5 to complete the fixed-distance operation.

[0032] The connecting column 6 is provided with a distance scale, and the slider 8 is provided with a locking bolt. The position of the slider 8 can be adjusted according to needs to adjust the length of the woven bag cut.
