Two support plates are fixedly installed on the top of the base plate. Two sliding holes are opened on the top surface of the base plate, and the support plates are slidably connected to the top surface of the base plate. The middle of the two support plates is threadedly connected to the bidirectional threaded rod. This application adjusts the distance between the support plates by cooperating with the motors, the bidirectional threaded rods, the support plates, and the sliding holes of the base plate. The motors drive the bidirectional threaded rods to rotate, so that the support plates can adapt to rollers of different widths and adjust the distance. However, the above device cannot cut kraft paper to a fixed length, resulting in a large error in the finished product. Utility Model Content

[0004] In order to improve the problem that the aforementioned device cannot cut kraft paper to a fixed length, resulting in large errors in the finished product, this utility model provides a fixed-length cutting device for kraft paper processing.

[0005] This utility model provides a fixed-length cutting device for kraft paper processing, which adopts the following technical solution:

[0006] A fixed-length cutting device for kraft paper processing includes a base, a support frame mounted on the left end of the top of the base, a roller mounted on the top of the support frame, an mounting plate mounted on the top of the base near the support frame, a pre-drilled hole on the mounting plate, a second electric push rod mounted on the top of the mounting plate, a longitudinal moving mechanism mounted at the bottom of the second electric push rod, a cutter mounted at the bottom of the longitudinal moving mechanism, a second fixing mechanism mounted on the side of the mounting plate near the cutter, a transverse moving mechanism mounted on the right end of the top of the base, a pointer mounted at the bottom of the transverse moving mechanism, scale lines engraved on the base below the pointer, and a first fixing mechanism mounted on the top of the transverse moving mechanism.

[0007] By adopting the above technical solution, the horizontal moving mechanism drives the first fixing mechanism and the pointer to move, reads the value of the scale line, and makes it convenient to adjust the distance between the cutter and the pointer according to actual needs. After the adjustment is completed, the kraft paper is released by the roller and passes through the reserved hole. The end of the kraft paper is fixed by the first fixing mechanism and further fixed by the second fixing mechanism. Finally, the second electric push rod is controlled to extend and drive the vertical moving mechanism to move down. The vertical moving mechanism drives the cutter to move longitudinally to cut the kraft paper.

[0008] Optionally, the longitudinal moving mechanism includes a rectangular plate, which is installed at the bottom of the second electric push rod. Connecting plates are installed at both the front and rear ends of the bottom of the rectangular plate. A second one-way lead screw is connected between the two sets of connecting plates. A second motor for driving the rotation of the second one-way lead screw is installed on one set of connecting plates. A second nut is screwed to the outer wall of the second one-way lead screw. The bottom of the second nut is connected to the top of the cutter. A movable block is connected to the top of the second nut. A movable groove that slides with the movable block is opened at the bottom of the rectangular plate.

[0009] By adopting the above technical solution, when the second motor is working, it drives the second one-way lead screw to rotate. Under the sliding cooperation of the movable block and the movable groove, the rotation of the second one-way lead screw drives the second lead screw nut to move back and forth. The movement of the second lead screw nut drives the cutter to move back and forth, thereby enabling the cutting of kraft paper.

[0010] Optionally, the second fixing mechanism includes two sets of horizontal plates, both sets of horizontal plates are installed on the side of the mounting plate near the cutter, and a first electric push rod is installed at the end of each set of horizontal plates near the reserved hole. A movable plate is installed at the end of each set of first electric push rods that are close to each other.

[0011] By adopting the above technical solution, the first electric push rod extends and drives the movable plate to move, thereby fixing the kraft paper through the two sets of movable plates, making the kraft paper more stable during cutting.

[0012] Optionally, the lateral movement mechanism includes two sets of vertical plates, both sets of vertical plates are mounted on the top of the base, and a first one-way lead screw is connected between the two sets of vertical plates. A first motor for driving the first one-way lead screw to rotate is mounted on one set of vertical plates. A first nut is screwed to the outer wall of the first one-way lead screw. A guide rod is connected between the two sets of vertical plates near the end of the first one-way lead screw, and the guide rod is horizontally arranged with the first one-way lead screw. A movable sleeve is fitted on the outer wall of the guide rod, and the top of the movable sleeve is fixedly connected to the bottom of the first nut. The bottom of the movable sleeve is fixedly connected to the top of the pointer.

[0013] By adopting the above technical solution, when the first motor is working, it drives the first one-way lead screw to rotate. The rotation of the first one-way lead screw drives the first lead screw nut to move. The movement of the first lead screw nut drives the movable sleeve to slide along the smooth rod, which in turn drives the first fixed mechanism to move left and right, making it convenient to adjust the lateral position of the first fixed mechanism, so that the device can cut kraft paper of different lengths according to actual needs.

[0014] Optionally, the center line of the cutter and the left end of the scale line are on the same vertical line.

[0015] By adopting the above technical solution, it is possible to adjust the distance between the cutter and the pointer by reading the value of the scale line, thereby enabling the kraft paper to be cut to a fixed length.

[0016] Optionally, the first fixing mechanism includes a positioning seat, which is installed on the top of the first nut. A threaded rotating rod is screwed to the top of the positioning seat, a handwheel is installed on the top of the threaded rotating rod, and a positioning pressure plate is connected to the bottom of the threaded rotating rod. Rubber pads are connected to the bottom of the positioning pressure plate and the inner bottom wall of the positioning seat.

[0017] By adopting the above technical solution, the worker turns the handwheel, which drives the threaded rod to rotate. The rotation of the threaded rod causes the positioning pressure plate to move downward until the rubber pad comes into direct contact with the kraft paper, thereby fixing the end of the kraft paper.

[0018] Optionally, a slider is connected to the right end of the positioning plate, and a groove is provided on the inner side of the positioning seat to slide with the slider.

[0019] By adopting the above technical solution, when the positioning plate moves, it can drive the slider to slide inside the rubber pad, thereby limiting the positioning plate and ensuring that the positioning plate always maintains vertical movement.

[0020] In summary, this utility model has at least one of the following beneficial effects:

[0021] By cooperating with the cutter, scale lines, pointer, lateral movement mechanism, longitudinal movement mechanism, second electric push rod, and mounting plate, the scale line values ​​are read, making it easy to adjust the distance between the cutter and the pointer. This allows the device to cut kraft paper to a fixed length according to actual needs, improving the device's practicality.

[0022] The first fixing mechanism facilitates the fixing of the ends of the kraft paper, and the second fixing mechanism facilitates further fixing of the kraft paper, enabling the device to fix the kraft paper during cutting, thereby improving the cutting accuracy. Attached Figure Description

Detailed Implementation

[0028] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.

[0029] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 2This utility model provides an embodiment of a fixed-length cutting device for kraft paper processing, comprising a base 3, a support frame 2 mounted on the left end of the top of the base 3, a roller 1 mounted on the top of the support frame 2, an mounting plate 12 fixedly mounted on the top of the base 3 near the support frame 2, a pre-drilled hole 4 on the mounting plate 12, a second electric push rod 11 mounted on the top of the mounting plate 12, a longitudinal moving mechanism 10 mounted at the bottom of the second electric push rod 11, a cutter 6 mounted at the bottom of the longitudinal moving mechanism 10, and the longitudinal moving mechanism 10 including a rectangular plate 1006 mounted on the second electric push rod 11. At the bottom, connecting plates 1001 are fixedly installed at both the front and rear ends of the bottom of the rectangular plate 1006. A second one-way lead screw 1005 is rotatably connected between the two sets of connecting plates 1001. A second motor 1007 for driving the rotation of the second one-way lead screw 1005 is installed on one set of connecting plates 1001. A second nut 1002 is screwed to the outer wall of the second one-way lead screw 1005. The bottom of the second nut 1002 is fixedly connected to the top of the cutter 6. A movable block 1003 is connected to the top of the second nut 1002. A movable groove 1004 that slides with the movable block 1003 is opened at the bottom of the rectangular plate 1006. When the second motor 1007 is working, it drives the second one-way lead screw 1005 to rotate. Under the sliding cooperation of the movable block 1003 and the movable groove 1004, the rotation of the second one-way lead screw 1005 drives the second lead screw nut 1002 to move back and forth. The movement of the second lead screw nut 1002 drives the cutter 6 to move back and forth, thereby enabling the cutting of kraft paper.

[0030] Please refer to the attached diagram in the instruction manual. Figure 1 A second fixing mechanism 5 is provided on the side of the mounting plate 12 near the cutter 6. The second fixing mechanism 5 includes two sets of horizontal plates 503, both of which are installed on the side of the mounting plate 12 near the cutter 6. A first electric push rod 502 is fixedly installed at the end of each set of horizontal plates 503 near the reserved hole 4. A movable plate 501 is installed at the end of each set of first electric push rods 502 that is close to each other. The first electric push rod 502 extends and drives the movable plate 501 to move, thereby fixing the kraft paper through the two sets of movable plates 501, making the kraft paper more stable during cutting.

[0031] Please refer to the attached diagram in the instruction manual. Figure 1 A horizontal moving mechanism 9 is provided at the top right end of the base 3. A pointer 8 is fixedly installed at the bottom of the horizontal moving mechanism 9. A scale line 7 is engraved on the base 3 below the pointer 8. The center line of the cutter 6 is on the same vertical line as the left end of the scale line 7. Thus, by reading the value of the scale line 7, the distance between the cutter 6 and the pointer 8 can be adjusted, thereby enabling the kraft paper to be cut to a fixed length.

[0032] Please refer to the attached diagram in the instruction manual. Figure 1The top of the horizontal moving mechanism 9 is provided with a first fixing mechanism 13. The horizontal moving mechanism 9 includes two sets of vertical plates 905. Both sets of vertical plates 905 are installed on the top of the base 3. A first one-way lead screw 903 is connected between the two sets of vertical plates 905. A first motor 906 for driving the first one-way lead screw 903 to rotate is installed on one set of vertical plates 905. A first nut 902 is screwed to the outer wall of the first one-way lead screw 903. A guide rod 904 is connected between the two sets of vertical plates 905 near the end of the first one-way lead screw 903. The guide rod 904 is horizontally arranged with the first one-way lead screw 903. A movable sleeve 901 is sleeved on the outer wall of the guide rod 904. The top of the movable sleeve 901 is fixedly connected to the bottom of the first nut 902. The bottom of the movable sleeve 901 is fixedly connected to the top of the pointer 8. When the first motor 906 is working, it drives the first one-way lead screw 903 to rotate. The rotation of the first one-way lead screw 903 drives the first lead screw nut 902 to move. The movement of the first lead screw nut 902 drives the movable sleeve 901 to slide along the smooth rod 904, which in turn drives the first fixed mechanism 13 to move left and right, so as to facilitate the adjustment of the lateral position of the first fixed mechanism 13 and enable the device to cut kraft paper of different lengths according to actual needs.

[0033] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 3 The first fixing mechanism 13 includes a positioning seat 1303, which is fixedly installed on the top of the first nut 902. A threaded rotating rod 1302 is screwed to the top of the positioning seat 1303. A handwheel 1301 is installed on the top of the threaded rotating rod 1302. A positioning pressure plate 1305 is rotatably connected to the bottom of the threaded rotating rod 1302. Rubber pads 1307 are connected to the bottom of the positioning pressure plate 1305 and the inner bottom wall of the positioning seat 1303. When the operator rotates the handwheel 1301, the rotation of the handwheel 1301 drives the threaded rotating rod 1302 to rotate, which in turn drives the positioning pressure plate 1305 to move downward until the rubber pad 1307 comes into direct contact with the kraft paper, thereby fixing the end of the kraft paper.

[0034] Please refer to the attached diagram in the instruction manual. Figure 3 A slider 1306 is fixedly connected to the right end of the positioning plate 1305, and a groove 1304 is provided on the inner side of the positioning seat 1303 to slide with the slider 1306. When the positioning plate 1305 moves, it can drive the slider 1306 to slide inside the rubber pad 1307, thereby limiting the positioning plate 1305 and keeping it in vertical motion.

[0035] Working principle: When in use, adjust the distance between the cutter 6 and the pointer 8 according to the length of the kraft paper to be cut. First, turn on the first motor 906. The first motor 906 drives the first one-way lead screw 903 to rotate. The rotation of the first one-way lead screw 903 drives the first lead screw nut 902 to move to the left. The leftward movement of the first lead screw nut 902 drives the movable sleeve 901 to slide along the smooth rod 904, which in turn drives the pointer 8 to move to the left, making it convenient for the staff to read the value according to the pointer 8.

[0036] After the pointer 8 is adjusted to the appropriate position, the end of the kraft paper is pulled out from the roller 1, passes through the reserved hole 4, and makes the end of the kraft paper contact the inside of the positioning seat 1303. At this time, the operator manually turns the handwheel 1301. The rotation of the handwheel 1301 drives the threaded rotating rod 1302 to rotate. Under the sliding cooperation of the slide groove 1304 and the slider 1306, the rotation of the threaded rotating rod 1302 drives the positioning pressure plate 1305 to move downward, so that the rubber pad 1307 directly contacts the kraft paper, thereby fixing the end of the kraft paper.

[0037] Then, control the first electric push rod 502 to extend. The extension of the first electric push rod 502 drives the movable plate 501 to move towards the kraft paper until the two sets of movable plates 501 clamp the kraft paper, thereby fixing the kraft paper again. At this time, control the second electric push rod 11 to extend. The extension of the second electric push rod 11 drives the cutter 6 to move downward through the longitudinal moving mechanism 10 until the bottom of the cutter 6 is attached to the kraft paper.

[0038] Then the second motor 1007 is turned on. When the second motor 1007 is working, it drives the second one-way lead screw 1005 to rotate. With the sliding cooperation of the movable block 1003 and the movable groove 1004, the rotation of the second one-way lead screw 1005 drives the second lead screw nut 1002 to move back and forth, which in turn drives the cutter 6 to move back and forth to cut the kraft paper.

[0039] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
