Detailed implementation mode

[0027] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] Embodiment: A high-speed slitter with automatic feeding, including a mounting base 1, a discharge roller 2 and a tool rest 6. After all cutting is completed, the worker removes the take-up reel 701 from the winding roller. The winding roller is generally positioned and disassembled by controlling the outer diameter. The entire take-up process includes: adjusting the outer diameter of the winding roller, pushing down the winding roller, installing a new winding roller, and adjusting the outer diameter of the winding roller. The above take-up process is rather cumbersome, resulting in low discharging efficiency. To address the above problems, the present solution is improved, and the specific solution is as follows:

[0030] Reference Figures 1 - 9 ; To facilitate the disassembly and installation of the take-up reel 701, the present solution changes the original installation method and provides a take-up assembly 7, including an installation plate 3 installed on the mounting base 1. Two mounting brackets 4 are installed on the installation plate 3, and a plurality of take-up reels 701 are rotatably installed on the mounting brackets 4; a disassembly and assembly component for disassembling the take-up reel 701, including a partition 401 fixedly installed on the mounting bracket 4. Mounting rods 702 are installed on the side walls of the partition 401 and the side wall of the installation plate 3. Installation grooves 703 are formed on the side walls of the mounting rods 702. Mounting blocks 705 matching the installation grooves 703 are installed on the outer walls of both sides of the take-up reel 701. Jack holes 704 communicating with the installation grooves 703 are formed on the mounting rods 702. Insertion rods 706 matching the jack holes 704 are installed on the mounting blocks 705, and a limiting groove is provided on the insertion rod 706, and a limiting block 707 is elastically installed in the limiting groove.

[0031] In this solution, the existing entire material receiving roller is divided into multiple mounting rods 702, and the spacing between the mounting rods 702 is the same. A material receiving disk 701 is installed between every two mounting rods 702. The installation method adopted in this solution is to open an installation groove 703 below the mounting rod 702. At the same time, a mating installation block 705 is provided on the side wall of the material receiving disk 701. Meanwhile, a jack 704 is provided above the installation groove 703. The installation block 705 is installed into the installation groove 703 from bottom to top, and the insertion rod 706 on the installation block 705 is inserted into the jack 704. When inserting, the limiting block 707 is pressed into the limiting groove under the pressure of the inner wall of the jack 704 until the limiting block 707 completely passes through the jack 704, and then the limiting block 707 pops out of the limiting groove and is stuck on the outer wall of the mounting rod 702 (it should be noted that, to ensure the stability after installation, the shortest distance between the limiting block 707 and the mounting block 705 is the same as the depth of the jack 704). Such an installation method does not require adjusting the pipe diameter of the material receiving roller during installation and disassembly, improving the convenience of installation and disassembly. And compared with the original sleeved installation method, such an installation position is more accurate.

[0032] Reference Figures 1 - 9 ; a discharging assembly, including a discharging ring 708 slidably installed on the mounting rod 702. A slider is fixedly installed on the discharging ring 708, and a chute matching the discharging ring 708 is opened on the mounting rod 702. A spring is connected between the outer wall of the slider and the inner wall of the chute. A slope is provided on the side of the discharging ring 708 away from the material receiving disk 701 to press the limiting block 707 by driving the discharging ring 708; the discharging assembly further includes a transmission frame 5 installed above the mounting frame 4. A first piston tube 11 is installed on the transmission frame 5. A first piston rod 12 is movably installed below the first piston tube 11. A detection frame 9 is installed on the first piston rod 12. A detection roller 10 is rotatably installed on the detection frame 9. A return spring is sleeved on the first piston rod 12. A second piston tube 13 is provided on the detection frame 9. A second piston rod 14 is provided below the second piston tube 13. The bottom end of the second piston rod 14 is fixedly installed with a discharging plate 15. An air outlet pipe 28 is provided on the first piston tube 11. An air inlet pipe 29 is connected to the air outlet pipe 28, and the air inlet pipe 29 is communicated with the second piston tube 13.

[0033] To facilitate the disassembly of the above-mentioned disassembly and assembly components, a discharging component is provided in this solution. A discharging ring 708 is slidably installed on the installation rod 702. By sliding the discharging ring 708, the limiting block 707 can be squeezed. After the limiting block 707 is pushed into the limiting groove, the limiting function between the installation block 705 and the installation groove 703 is lost (that is, the limiting function between the material receiving tray 701 and the installation rod 702 is lost). If the installation groove 703 faces downward at this time, the material receiving tray 701 will separate from the installation rod 702 under its own gravity. Further, an inclined plate can be provided on one side of the installation frame 4 for guiding and collecting the falling material receiving tray 701; or the distance between the material receiving tray 701 and the installation frame 4 can be increased, and a recycling box can be provided on the installation frame 4 to catch the falling material receiving tray 701. The above two methods are both for facilitating the recycling of the material receiving tray 701 and are not limited to the above two solutions.

[0034] The specific discharging process is as follows: The radius of the paper roll on the material receiving tray 701 gradually increases, and the paper roll presses the upper detection roller 10. The upward movement of the detection roller 10 drives the first piston rod 12 to compress the air in the first piston tube 11. The air in the first piston tube 11 enters the air outlet pipe 28, and then enters the air inlet pipe 29 from the air outlet pipe 28. The air in the air inlet pipe 29 enters the second piston tube 13. The air pressure in the second piston tube 13 increases, and the second piston rod 14 moves out of the second piston tube 13 (in the downward movement state) under the air pressure. The second piston rod 14 drives the discharging plate 15 to move downward. The downward movement of the discharging plate 15 presses the inclined surface on the discharging ring 708, causing the discharging ring 708 to approach the limiting block 707 and pressing the limiting block 707 into the limiting groove to complete the discharging, thus replacing manual discharging. It should be noted that, on the basis of this solution, an adjusting component for adjusting the position of the detection roller 10 can be added, which can be used for paper rolls with different radii.

[0035] Reference Figures 1 - 9 ; A connecting component is provided on the air inlet pipe 29. The connecting component includes a connecting pipe 30 connected to the air outlet pipe 28. An activity hole 32 is opened on the connecting pipe 30, and an activity plate 31 is movably installed in the activity hole 32. A through hole 33 is opened on the activity plate 31. An activity rod 8 is fixedly installed at the bottom of the activity plate 31, and the activity rod 8 penetrates the outer wall of the transmission frame 5 and is connected to the top wall of the detection frame 9.

[0036] In this solution, a connecting component is provided on the air inlet pipe 29 to control the time point of the movement of the second piston rod 14. When the detection frame 9 is pushed upward by the paper roll, it will drive the two activity rods 8 to move upward. The activity rods 8 drive the activity plate 31 to move upward. During the upward movement of the activity plate 31, the through hole 33 will gradually communicate with the inner hole of the connecting pipe 30 (before communication, the inner hole of the connecting pipe 30 is divided into two parts and the two parts are not connected). At this time, the air inlet pipe 29 can conduct air, so as to control the timing of discharging, further improving the flexibility of discharging.

[0037] Reference Figures 1 - 9 ; A reinforcement assembly is provided below the transmission frame 5. The reinforcement assembly includes a third piston tube 16 fixedly installed below the transmission frame 5, and a third piston rod 17 is movably installed below the third piston tube 16. A first permanent magnet 18 is fixedly installed at the bottom of the third piston rod 17, and a first iron plate 19 is adsorbed at the bottom of the first permanent magnet 18. A connection groove matching the bottom contour of the first permanent magnet 18 is formed on the first iron plate 19 (this can ensure that the position of the first iron plate 19 installed below the first permanent magnet 18 is the same each time). A reinforcement rod 20 is fixedly installed below the first iron plate 19, and a reinforcement groove is formed on the reinforcement rod 20, and a clamping block 21 is elastically installed in the reinforcement groove. A reinforcement plate 23 is fixedly installed on the material receiving tray 701, and a clamping hole 24 matching the reinforcement rod 20 is formed on the reinforcement plate 23. The third piston tube 16 is communicated with the air inlet pipe 29, and an elastic band 22 is provided on the first iron plate 19.

[0038] When the paper roll is completed with slitting and material receiving, it is necessary to fix the paper head (to prevent the paper roll from unrolling and becoming loose). Therefore, in this solution, a reinforcement assembly is provided below the transmission frame 5. When the connection assembly is connected (at this time, it is about to unload the material), the air in the air inlet pipe 29 enters the third piston tube 16, and the third piston rod 17 is pushed out of the third piston tube 16 by the air pressure action (in the downward movement state). The third piston rod 17 drives the first permanent magnet 18 and the first iron plate 19 below it to move downward. The first iron plate 19 drives the reinforcement rod 20 to be inserted into the corresponding clamping hole 24. The clamping block 21 on the reinforcement rod 20 is first squeezed into the reinforcement groove and then pops out of the reinforcement groove, and the elastic band 22 presses on the outer wall of the paper roll to fix the outermost paper tape of the paper roll and prevent it from unrolling. It should be noted that in order to ensure the reinforcement step before unloading, the inner diameter of the third piston tube 16 can be made smaller than that of the second piston tube 13 (that is, with the same air intake, the third piston rod 17 is subjected to greater air pressure and the rod comes out faster).

[0039] Reference Figures 1 - 9 ; A positioning assembly, installed on the mounting frame 4, is used to adjust the position of the material receiving tray 701. The positioning assembly includes a mounting tube 25 fixedly installed on the mounting frame 4, and an electromagnet 34 is fixedly installed in the mounting tube 25. A second permanent magnet 26 is movably installed in the mounting tube 25, and a second iron plate 27 is fixedly installed on the material receiving tray 701.

[0040] In order to ensure that the installation groove 703 is always downward during unloading, in this solution, an installation pipe 25 is installed on the installation frame 4. When unloading, the electromagnet 34 in the installation pipe 25 is energized, and the repulsive force between the electromagnet 34 and the second permanent magnet 26 is used to drive the second permanent magnet 26 to move upward. On the one hand, the second permanent magnet 26 can hold the second iron plate 27, and on the other hand, the second iron plate 27 can be attracted by the second permanent magnet 26. In this way, the stopping position of the installation rod 702 can be controlled to ensure that the receiving tray 701 can fall by its own gravity during unloading. Subsequently, the staff only needs to install a new receiving tray 701, which further improves the convenience of unloading.
