Description

Technical Field

[0001] This utility model belongs to the field of slitting machine technology, specifically a slitting machine for sheet roll paper printing lines. Background Technology

[0002] In the packaging, printing, and paper processing industries, sheet and roll paper is a common basic material that needs to undergo processes such as crease marking and slitting before it can be used. The crease marking process mainly involves pressing crease lines on the paper surface to facilitate folding and ensure the accuracy and aesthetics of the folding process. The slitting process involves cutting large sheet and roll paper into rolls or sheets of specific widths according to actual needs to meet the size requirements of different products.

[0003] When a slitting machine operates continuously for extended periods, the frequent contact and cutting of the paper by the blades inevitably leads to wear and tear, causing the blades to gradually become dull. Dull blades not only result in rough and uneven edges on the slit paper, severely impacting the product's appearance quality, but also increase resistance during the slitting process, increasing the motor load and consuming more energy, thus raising production costs. More importantly, traditional slitting machines often rigidly fix the blades directly to the slitting mechanism. This method makes replacing dull blades extremely inconvenient for workers, typically requiring the use of various complex tools and significant time spent disassembling and reassembling the blades. This severely impacts production continuity and reduces efficiency. Therefore, to address these issues, a slitting machine for sheet roll paper printing lines is proposed. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, a paper roll printing line slitting machine is proposed.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The plate roll paper printing line slitting machine of this utility model includes a processing frame; a fixing plate is fixedly connected to the inner side wall of the processing frame, and a first telescopic rod is fixedly connected to both sides of the inner wall of the processing frame. A positioning plate is fixedly connected to the other end of the first telescopic rod, and a replacement plate is rotatably connected to the other end of the positioning plate. A positioning component is provided on the processing frame, and the positioning component is used to rotate and position the replacement plate.

[0006] The processing rack is equipped with a slitting mechanism, which includes a mounting bracket fixedly connected to one side of the changing disc. A mounting block is slidably connected inside the mounting bracket. A threaded hole is opened on one side of the mounting bracket, and a bolt is threaded into the threaded hole. One end of the bolt extends out of the threaded hole and is inserted into a positioning hole opened on one side of the mounting block. One end of the mounting block extends out of the mounting bracket and is fixedly connected to a cutting tool. Through the arrangement and cooperation of the slitting mechanism and the changing disc, it is easy to quickly switch the cutting tool to reduce the impact on slitting efficiency.

[0007] Preferably, a fixed frame is fixedly connected to one side of the processing frame, and a transmission rod is rotatably connected to the inner side wall of the fixed frame. The other end of the transmission rod passes through a through hole opened on one side of the processing frame and is fixedly connected to the replacement disc. The transmission rod and the fixed frame facilitate the support and positioning of the replacement disc, thereby reducing the pressure on the multiple telescopic rods.

[0008] Preferably, the positioning component includes a fixing block formed on one side of the processing frame, a limiting hole formed on the top of the fixing block, a limiting rod slidably connected in the limiting hole, and the bottom end of the limiting rod inserted into a fixing hole formed on the outer wall of the transmission rod. The positioning component is positioned by the cooperation of the fixing block, the limiting hole and the limiting rod.

[0009] Preferably, a knob is fixedly connected to the top of the limiting rod, and the outer wall of the knob is provided with anti-slip texture. By setting the knob, it is easy to move the limiting rod by pulling the knob, and avoid slipping when operating the limiting rod.

[0010] Preferably, a protective frame is fixedly connected to one side of the mounting bracket. The protective frame is L-shaped. The protective frame facilitates the movement and positioning of the bolts, preventing them from falling completely out of the threaded hole onto the fixed plate during the cutting process, which would require stopping the machine to retrieve them.

[0011] Preferably, a rotating roller is rotatably connected to one side of the inner wall of the processing frame via a rotating shaft, and the outer wall of the rotating roller is provided with an anti-slip layer. The rotating roller facilitates the forward movement of the paper.

[0012] Preferably, a base is fixedly connected to one side of the processing frame, and a motor is fixedly connected to the top of the base. The output end of the motor passes through a drive hole opened on one side of the processing frame and is fixedly connected to one end of the rotating roller.

[0013] The beneficial effects of this utility model are:

[0014] This utility model provides a slitting machine for sheet roll paper printing lines. Through the setting and cooperation of the slitting mechanism and the changing disc, it is easy to quickly switch blades to reduce the impact on slitting efficiency. When the blades wear out, during the intermittent movement of the paper, rotate the bolt corresponding to the blade located in the upper half of the two blades, pull out the blade and replace it with a new one. Rotate the bolt corresponding to the new blade, and the bolt will turn into the positioning hole to lock the new blade. Quickly rotate the changing disc 180 degrees to swap the positions of the damaged blade and the new blade. Loosen the limit rod and press it down, and the limit rod will re-insert into the fixing hole. Rotate the limit rod and the changing disc to rotate and position. Rotate the bolt corresponding to the damaged blade, pull out the damaged blade and replace it with a new one. When it is necessary to replace the blade, repeat the above steps. The blades are easy to replace and do not affect the slitting efficiency of the paper. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] Please see Figures 1-5 This utility model provides a paper roll printing line slitting machine, including a U-shaped processing frame 1; a rectangular fixing plate 2 is fixedly connected to the inner side wall of the processing frame 1, and multiple transmission rollers 16 are rotatably connected to the inner side wall of the processing frame 1 through a rotating shaft, which are used to push the paper roll to move.

[0026] A rotating roller 15 is rotatably connected to one side of the inner wall of the processing frame 1 via a rotating shaft. The outer wall of the rotating roller 15 is provided with an anti-slip layer. The rotating roller 15 facilitates the forward movement of the paper. A base 14 is fixedly connected to one side of the processing frame 1. A motor is fixedly connected to the top of the base 14. The output end of the motor passes through a drive hole opened on one side of the processing frame 1 and is fixedly connected to one end of the rotating roller 15. The base 14 and the motor facilitate the provision of a drive source for the rotating roller 15.

[0027] Three annularly distributed first telescopic rods 3 are fixedly connected to both sides of the inner wall of the processing rack 1. A circular positioning plate 4 is fixedly connected to the other end of the first telescopic rod 3. A circular replacement plate 5 is rotatably connected to the other end of the positioning plate 4. It should be noted that the first telescopic rod 3 is a telescopic rod in the prior art, which is a mature existing technology. The first telescopic rod 3 consists of a cylindrical telescopic tube with a telescopic hole on one side. A telescopic block is slidably connected inside the telescopic tube. A connecting rod is fixedly connected to the side of the telescopic block near the telescopic hole. The other end of the connecting rod passes through the telescopic hole, extends out of the telescopic tube, and is fixedly connected to the replacement plate. The above is a description of the first telescopic rod 3.

[0028] The processing frame 1 is equipped with a positioning component, which includes a rectangular fixing block 9 fixedly connected to one side of the processing frame 1. The top of the fixing block 9 is provided with a circular limiting hole, and a cylindrical limiting rod 10 is slidably connected in the limiting hole. The bottom end of the limiting rod 10 is inserted into a circular fixing hole 11 opened on the outer wall of the transmission rod 8. Through the cooperation of the fixing block 9, the limiting hole and the limiting rod 10, the positioning component is used to rotate and position the changing disc 5.

[0029] A hexagonal knob 12 is fixedly connected to the top of the limiting rod 10. The outer wall of the knob 12 is provided with anti-slip texture. By setting the knob 12, it is easy to move the limiting rod 10 by pulling the knob 12, so as to avoid slipping when operating the limiting rod 10.

[0030] A U-shaped fixed frame 7 is fixedly connected to both sides of the processing frame 1. A transmission rod 8 is rotatably connected to the inner side wall of the fixed frame 7. The other end of the transmission rod 8 passes through a circular through hole opened on one side of the processing frame 1 and is fixedly connected to the replacement disc 5.

[0031] The transmission rod 8 and the fixed frame 7 facilitate the support and positioning of the replacement disc 5, thereby reducing the pressure on multiple telescopic rods.

[0032] The processing rack 1 is equipped with a cutting mechanism 6. The cutting mechanism 6 includes a U-shaped mounting bracket 61 fixedly connected to one side of the changing plate 5. A rectangular mounting block 62 is slidably connected inside the mounting bracket 61. A threaded hole 64 is opened on one side of the mounting bracket 61. A bolt 63 is threadedly connected inside the threaded hole 64. One end of the bolt 63 extends out of the threaded hole 64 and is inserted into a positioning hole 66 opened on one side of the mounting block 62. One end of the mounting block 62 extends out of the mounting bracket 61 and is fixedly connected to a cutting tool 65.

[0033] The mounting bracket 61 and its mounting block 62, thread and tool 65 are provided in two, and the two matching structures are distributed in a ring at equal intervals.

[0034] A protective frame 13 is fixedly connected to one side of the mounting bracket 61. The protective frame 13 is L-shaped. The protective frame 13 facilitates the movement and positioning of the bolt 63, preventing the bolt 63 from completely dislodging from the threaded hole 64 and falling onto the fixed plate 2 that is currently being cut, requiring the machine to be stopped and picked up.

[0035] A U-shaped limiting frame can be fixedly connected to both sides of the processing frame 1 as needed. An electric telescopic rod is fixedly connected to the inner wall of the limiting frame. The other end of the electric telescopic rod passes through the through hole opened on one side of the processing frame and is fixedly connected to the positioning plate 4. The electric telescopic rod replaces the manual push of the changing plate 5 to move back and forth, which is more in line with automated processing.

[0036] This is an alternative option, therefore the electric telescopic pole and its supporting structure are not shown in the figure. If necessary, they can be installed on the processing frame 1 according to this description. Meanwhile, the control and power supply of the electric telescopic pole are existing mature technologies, and will not be described in detail.

[0037] The combination of the slitting mechanism 6 and the changing disc 5 facilitates the rapid switching of the cutting tool 65, thereby reducing the impact on slitting efficiency.

[0038] Based on the above structure, the present invention includes the following implementation process:

[0039] The paper is wound around the outside of one of the drive rollers 16, then one end of the paper is passed through the lower end of one of the drive rollers 16, and then the paper is passed through the upper ends of two of the drive rollers 16, and then the paper is passed through the middle of the rotating roller and the fixed plate 2, so that the rotating roller 15 clamps the paper at the upper end of the fixed plate 2.

[0040] The motor is started to drive the rotating roller 15 to rotate, pushing the paper to the bottom of the cutter 65. The replacement plate can be manually pushed and the cutter 65 fixed on it can be moved through the mounting bracket 61 and mounting block 62 to cut the paper. This operation can also be performed by starting the electric telescopic rod, and then the motor is started again at a timer.

[0041] It should be noted that the motor is powered by an external power source connected to a cable. The selection of the motor model and the controller for controlling the motor's timed start are mature technologies in this field, so they will not be elaborated on further.

[0042] When the blade 65 wears out, during the interval when the motor starts driving the paper to move at regular intervals, that is, just after one slitting is completed and the paper is being pushed forward, rotate the bolt 63 corresponding to the upper blade 65 of the two blades 65, so that the bolt 63 turns out of the positioning hole 66, releases the limit on the mounting block 62, and pulls out the blade 65 to replace the new blade 65.

[0043] Then, during the interval of driving the paper to move, rotate the bolt 63 corresponding to the new cutter 65 so that the bolt 63 turns into the positioning hole 66, thus locking the new cutter 65.

[0044] Then, during the intermittent movement of the paper, pull up the limit rod 10 and quickly rotate the replacement disc 5 180 degrees, so that the positions of the damaged blade 65 and the new blade 65 are swapped, with the damaged blade 65 on top and the new blade 65 on the bottom. Release the limit rod 10 and press it down, so that the limit rod 10 is inserted into the fixing hole 11 again. Rotating the limit rod 10 will rotate the replacement disc 5, and the paper cutting can continue.

[0045] Similarly, during the subsequent intervals of driving the paper movement, rotate the bolt 63 corresponding to the damaged blade 65 so that the bolt 63 turns out of the positioning hole 66, release the limit on the mounting block 62, pull out the damaged blade 65 and replace it with a new blade 65. When it is necessary to replace the blade 65, repeat the above steps. The blade 65 is easy to replace and does not affect the paper cutting efficiency.

[0046] It should be noted that the above replacement steps can be performed by stopping the slitting machine as needed, i.e., stopping the motor and electric telescopic rod, and then operating. Different methods can be selected according to the length of the interval between driving the paper movement. However, compared with the replacement of the blade 65 in the prior art, the rotation of the replacement method in this technology does not affect the ease of replacement of the blade 65 and does not affect the paper slitting efficiency.
