DETAILED DESCRIPTION

[0043] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in an exemplary manner in conjunction with the accompanying drawings.

[0044] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0045] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. However, if it is indicated as a direct connection, it means that the two connected bodies are not connected through an intermediate structure, but are only connected to form a whole through a connecting structure. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0046] In order to realize the industrial automation of paper mills and packaging printing industries, reduce the difficulty of operation, labor intensity and production safety of on-site operators, and improve production efficiency and product quality, a highly automatic, precise and safe slitting equipment is designed, a complete set of automatic paper cutting system, and the entire cutting operation only requires one person to operate and monitor.

[0047] like Figures 1 to 14 As shown, the present application provides a high-precision single-blade dual-rotation fully synchronous slitting device for straightening, cutting, and rolling raw paper barrels into paper tubes of different widths.

[0048] like Figure 1-Figure 3 As shown, the high-precision single-blade double-rotation fully synchronous slitting equipment of the present invention includes a mounting bracket 1, a paper loading mechanism 2, a paper pulling mechanism 3, a paper cutting mechanism 4, a paper feeding mechanism 5 and a paper receiving mechanism 6. The mounting bracket 1 serves as a supporting frame for the main equipment. The mounting bracket 1 includes a left bracket 11 and a right bracket 12. An equipment mounting cavity 10 is formed between the left bracket 11 and the right bracket 12. An electric control box 7 is arranged on the right bracket 12.

[0049] The paper pulling mechanism 3, the paper cutting mechanism 4, the paper feeding mechanism 5 and the paper receiving mechanism 6 are all installed and fixed in the installation cavity 10, and the paper loading mechanism 2, the paper pulling mechanism 3, the paper cutting mechanism 4, the paper feeding mechanism 5 and the paper receiving mechanism 6 are all electrically connected to the electric control box 7 and controlled and adjusted by the electrical components inside the electric control box 7.

[0050] The control system is arranged in the electric control box 7, which mainly includes a main controller and a sensor network. The main controller is the core control unit of the equipment and is responsible for coordinating the operation of the entire equipment. It receives signals from various sensors (such as material conveying speed sensor, tool speed sensor, slitting position sensor, etc.), and uniformly manages and controls the rotation of the tool, double rotary motion, material conveying, and slitting adjustment according to preset slitting parameters (such as slitting width, slitting speed, material conveying speed, etc.). The sensor network is composed of multiple different types of sensors, which are distributed in different parts of the equipment, and are used to monitor the operating status of the equipment, the characteristics of the material, and various parameters in the slitting process in real time, and promptly feed back the monitored information to the main controller so that the main controller can make corresponding adjustments and controls according to the actual situation.

[0051] like Figure 4-Figure 6As shown, the paper loading mechanism 2 of the present invention is arranged on one side of the mounting bracket 1. The paper loading mechanism 2 is used to fix and rotate the base paper barrel 9, and load the paper 91 at a certain speed. The maximum design speed is 350M / M in, and the general operating speed is 200-300M / min. The paper loading mechanism 2 mainly includes a hydraulic double arm 21 and a double arm adjustment device 22. The hydraulic double arm 21 is used to fix and unwind the base paper barrel 9. The hydraulic double arm 21 clamps the base paper barrel 9 and lifts it to a suitable height. The double arm adjustment device 22 can be used to adjust the distance between the hydraulic double arms 21.

[0052] The base paper barrel 9 is lifted and the tension is controlled by the automatic hydraulic double arms 21 and the double arm adjustment device 22. The base paper barrel 9 can be automatically raised and lowered according to the base paper barrel 9 with different roll diameters to realize automatic flattening of the paper 91.

[0053] Specifically, Figure 7-Figure 8 As shown, the automatic hydraulic double arm 21 of the present invention includes a hydraulic mounting plate 211 and two hydraulic supports 212. At the same time, a movable connecting rod 210 is arranged between the two hydraulic supports 212. The two ends of the movable connecting rod 210 are respectively fixed on the two hydraulic supports 212. The movable connecting rod 210 has a telescopic function and plays a connecting and supporting role.

[0054] A hydraulic arm 213 is provided on each hydraulic support 212 . The double-arm adjusting device 22 is fixed on the hydraulic mounting plate 211 . One end of the double-arm adjusting device 22 is connected to one of the hydraulic supports 212 .

[0055] After the base paper barrel 9 is placed at the set position and the angle is adjusted, the hydraulic arm 213 is used to rotate, lift and clamp the base paper barrel 9. The hydraulic arm 213 is automatically centered and the paper roll height device is automatically adjusted according to the base paper barrel 9 during the paper cutting process. The equipment is also provided with a roll diameter detection system to monitor the paper roll diameter. When the paper roll has the minimum diameter, the system is shut down to avoid repeated paper feeding work.

[0056] like Figure 8 As shown, one end of each hydraulic arm 213 is rotatably connected to the hydraulic support 212, and the other end of each hydraulic arm 213 is rotatably connected to a reeling clamp 214, and a brake assembly 215 is provided on the back of the reeling clamp 214. The application of the brake assembly 215 can provide a stable braking force to ensure the stability of the paper tension according to the change of the pulling force value generated by the change of the vehicle speed and the self-weight rotation torque of the base paper drum 9.

[0057] In order to adjust the lateral position of the base paper barrel 9 or unwind base paper barrels 9 of different lengths, a double-arm adjustment device 22 is provided to adjust the lateral distance between the two hydraulic arms 213 .

[0058] The hydraulic mounting plate 211 and the two hydraulic supports 212 are movably connected. An adjusting connecting rod 216 is arranged between one end of the hydraulic mounting plate 211 and each hydraulic support 212. The hydraulic support 212 is slidably connected to the adjusting connecting rod 216. Limiting rings 217 are arranged at both ends of the adjusting connecting rod 216. The hydraulic support 212 can be displaced in parallel on the adjusting connecting rod 216, and its left and right movement range is limited by the limiting rings 217 arranged at both ends.

[0059] Specifically, Figure 8-Figure 9 As shown, the double-arm adjustment device 22 includes an adjustment cylinder 221 and a cylinder telescopic rod 222, one end of which is fixed on one of the hydraulic supports 212, and the cylinder telescopic rod 222 pushes the corresponding hydraulic support 212 to move on the adjustment connecting rod 216. According to the length of the base paper barrel 9, the adjustment cylinder 221 controls the cylinder telescopic rod 222 to extend and retract to adjust the relative distance between the two hydraulic supports 212, thereby controlling the distance between the two hydraulic supports 212, so that the unwinding clamp 214 can accurately clamp the base paper barrel 9 and release the paper according to the aligned cutting position.

[0060] like Figure 4-Figure 6 As shown, the paper pulling mechanism 3 of the present invention is arranged between the paper feeding mechanism 2 and the mounting bracket 1, and is used to straighten the paper 91 unrolled from the base paper barrel; the paper pulling mechanism 3 includes a plurality of deflection correction guide rollers 31, and each deflection correction guide roller 31 is arranged in sequence at intervals up and down, and the two ends of each deflection correction guide roller 31 are rotatably connected to the mounting bracket 1 or the hydraulic bracket 212.

[0061] The surface material and roughness of the guide roller are selected according to the material characteristics. For example, for plastic films with smooth surfaces, the guide roller surface may be coated with rubber to increase friction and prevent the material from slipping during transportation. Its diameter, length and arrangement are designed according to the scale of the slitting equipment and the size of the slitting material to ensure smooth and uniform material transportation. The drive device provides power to the guide roller so that the material is transported at the set speed. Common drive methods include motor combined with belt drive, chain drive or gear drive, etc., through which power is transmitted to the guide roller to achieve synchronization of the material and the cutter slitting action. Variable frequency speed regulation technology is used to flexibly adjust the material conveying speed according to the slitting requirements.

[0062] In order to improve the overall cutting accuracy, such as Figure 10-11 As shown, the paper cutting mechanism 4 provided in the present invention is fixed on the mounting bracket 1, and the paper cutting mechanism 4 mainly comprises a double-rotating paper cutting device 41 and a paper cutting driving device 42, wherein the double-rotating paper cutting device 41 cuts the paper 91 into different widths; and cuts the paper 91 into cut paper 92 of different widths;

[0063] The double-rotating paper cutting device 41 of the present invention is mainly used for precise slitting of paper. It can slit the rewound paper roll into paper within the width specifications, with a cutting length deviation less than 0.15mm and a squareness less than 0.3mm according to the downstream packaging or printing market requirements.

[0064] Specifically, Fig.10 As shown, a protective cover 43 is provided on the top of the double-rotation paper cutting device 41, and the double-rotation paper cutting device 41 includes two synchronous connection plates 411, and a first cutting roller 412 and a second cutting roller 413 are provided between the two synchronous connection plates 411. A plurality of cutting blades 414 are provided on the first cutting roller 412 and the second cutting roller 413, and the distance between each cutting blade 414 can be adjusted according to the actual cutting width, so as to cut out slit paper 92 of different widths. Through the double cutting of the first cutting roller 412 and the second cutting roller 413, it is ensured that the double-rotation motion of the cutting blade 414 is closely matched with the conveying and slitting action of the paper 91.

[0065] A cutting drive wheel 415 is disposed at one end of each of the first cutting roller 412 and the second cutting roller 413 , and the two cutting drive wheels 415 are meshed with gears.

[0066] One end of the regulating turbine is connected to one of the synchronous connecting plates 411 , and the regulating worm 441 causes the gear of the regulating turbine 442 to move up and down, thereby driving the synchronous connecting plate 411 to move up and down.

[0067] The paper cutting drive device 42 includes a paper cutting drive motor 421 and a lower knife roller 422 . A synchronous belt 423 is provided between one end of the lower knife roller 422 and the paper cutting drive motor 421 . The lower knife roller 422 is gear-engaged with the cutting drive wheel 415 .

[0068] When facing papers of different materials, different widths need to be cut or different cutting forces need to be used. One end of the first cutting roller 412 is provided with a slitting width adjusting device 44, and the slitting width adjusting device 44 includes an adjusting worm 441 and an adjusting turbine 442.

[0069] The slitting width adjustment device is used to adjust the distance between the cutter and the edge of the material, thereby achieving precise control of the slitting width. By adopting a screw drive mechanical structure, the worm 441 is rotated to adjust the turbine 442, which drives the lateral position of the cutting blade 414, and then the wide material is slit into narrow materials of different widths according to production requirements.

[0070] After the cutting is completed, the paper 91 needs to be fed again and wound into a roll.

[0071] In order to improve the quality of winding, Figure 12-13 As shown, the paper feeding mechanism 5 of the present invention includes a tension adjustment device 51 and two paper feeding rollers 52. The paper feeding mechanism 5 is arranged at the rear end of the paper cutting mechanism 4 to straighten and transport the cut paper 91 respectively; the two ends of the paper feeding rollers 52 are rotatably connected to the mounting bracket 1 to provide a conveying force for the cut paper 92. The tension adjustment device 51 can adjust the conveying pressure of the paper so that

[0072] Another technical point of the present invention is to set the tension adjustment device 51, such as Fig.12 As shown, the tension adjustment device 51 includes a tension adjustment frame 511, on which two tension adjustment rods 512 are arranged, and a rotating shaft 513 is arranged on the tension adjustment frame 511, and both ends of the rotating shaft 513 are rotatably connected to the mounting bracket 1, and one end of the rotating shaft 513 is provided with a tension adjustment gear 515 and a tension adjustment motor 514, and the main shaft of the tension adjustment motor 514 is gear-engaged with the tension adjustment gear 515;

[0073] The tension adjustment motor 514 rotates forward and reversely to drive the tension adjustment gear 515 and the rotating shaft 513 to rotate, so that the tension adjustment frame 511 deflects, and the distance between the two tension adjustment rods 512 and the paper feeding rod 52 provided on the tension adjustment frame 511 changes, thereby adjusting the surface tension of the cut paper 92. When the surface tension of the cut paper 92 is too large, the distance between the tension adjustment rod 512 and the paper feeding rod 52 is shortened, and when the surface tension of the cut paper 92 is too small, the distance between the tension adjustment rod 512 and the paper feeding rod 52 is increased. In the process of conveying and winding the cut paper 92, a suitable tension is always maintained, thereby improving the overall winding quality.

[0074] There are two paper feeding rollers 52 , which are rotatably fixed above the tension adjustment roller 512 , and the two paper feeding rollers 52 and the tension adjustment roller 512 are sequentially arranged up and down with a gap.

[0075] The paper collection mechanism 6 includes a paper collection motor 61 and a plurality of paper collection rollers 62 , each of which is provided with a plurality of paper collection rolls 63 . Each paper collection roll 63 is used to roll up the cut paper 92 .

[0076] In order to improve the cutting quality of the cutting blade 414 and monitor and adjust the tension adjustment device 51, the present invention further provides a paper detection mechanism 8.

[0077] like Figure 1 , 14As shown, the paper detection mechanism 8 is arranged between the paper feeding mechanism 5 and the paper receiving mechanism 6, and the left bracket 11 and the right bracket 12 are respectively provided with detection support rods 13. The sheet detection mechanism 8 includes a horizontal moving rod 81 and a detection bracket 82. The two ends of the horizontal moving rod 81 are respectively slidably fixed on the two detection support rods 13. The detection bracket 82 reciprocates on the horizontal moving rod 81, and a detection camera 83 is provided on the detection bracket 82.

[0078] The detection camera 83 can accurately detect the width data of the cut paper 92 and the line quality of the edge of the paper, and feed back the signal to the control system. The control system adjusts the cutting action of the cutting tool according to the feedback signal, and controls the tension adjustment device 51 at the same time to ensure that the cutting position is accurate and the width of the material after cutting is uniform.

[0079] The invention provides an adjustable paper feeding mechanism, and the hydraulic double arms can be automatically centered. According to the paper roll in the paper cutting process, the height device of the paper roll can be automatically adjusted. The application of the brake assembly can provide a stable braking force to ensure the stability of the paper tension according to the change of the pulling force value generated by the change of the vehicle speed and the rotation torque of the paper roll. The double-arm adjustment device can adjust the lateral feeding position of the base paper barrel and can adapt to base paper barrels of different sizes. By providing a double-rotating paper cutting device, two groups of cutting blades are arranged inside, and the double cutting realizes the synchronous precise size cross-cutting function of the paper length to ensure the accuracy of the cut paper.
