Technical Field

[0002] A blanking machine, also called a cutting device or a numerical control stamping device, generally needs to process some functional units (such as through holes) at equal intervals in the length direction of a coil during the processing of the coil. These functional units are generally processed by a die-cutting device. Specifically, for each blanking of a functional unit by the blanking machine, the reel rotates to pull the coil forward by a certain distance for the processing of the next functional unit.

[0003] However, it is difficult to ensure that the coil is not offset during the feeding process. Once the feeding is offset, it will seriously affect the alignment accuracy during blanking. At present, manual deviation rectification is generally used for the offset of the coil feeding, but manual deviation rectification can only rectify the situation with a large position offset and cannot perform real-time monitoring.

[0030] In order to make the technical problems, technical solutions and beneficial effects solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0031] Specific embodiments, in combination with Figures 1 to 9 As shown, the technical solution of the present utility model is further described. An automatic deviation-correcting punching machine includes a feeding mechanism 10, the feeding mechanism 10 is connected to a tensioning mechanism 20 for tensioning a roll of paper, and the tensioning mechanism 20 is connected to a conveying mechanism 30 for conveying the straightened roll of paper to a punching mechanism for paper cutting on the discharging side. The feeding mechanism 10 includes a monitoring device 11 for monitoring whether the roll of paper is offset during feeding and a deviation-correcting device 12 for automatically correcting the deviation when the monitoring device 11 detects that the roll of paper is offset during feeding. Through the cooperation of the monitoring device 11 and the deviation-correcting device 12, the punching machine monitors the feeding process of the roll of paper in real time, and can perform instant automatic adjustment when deviation occurs, avoiding the problem of material waste caused by the offset of the roll of paper during feeding, thereby reducing the production waste rate and improving the material utilization rate; at the same time, compared with manual deviation correction, automatic deviation correction not only improves the production efficiency, but also reduces the occurrence of human errors.

[0032] Further, as a preferred implementation manner rather than a limitation of this solution, the deviation-correcting device 12 includes a deviation-correcting motor 121 and a deviation-correcting feeding component 122 that is controlled by the deviation-correcting motor 121 to perform left-right deviation correction and can rotate up and down to lift the roll paper tube for feeding. A pulling member 123 for pulling the deviation-correcting feeding component 122 to move and correct the deviation during deviation correction is provided between the deviation-correcting motor 121 and the deviation-correcting feeding component 122;

[0033] Among them, the deviation-correcting feeding component 122 includes a hydraulic rod 1221 and a hydraulic cylinder 1222 for controlling the hydraulic rod 1221 to slide and stretch.

[0034] In this embodiment, the deviation-correcting motor can accurately control the movement and deviation correction of the deviation-correcting feeding component, ensuring the alignment during the feeding process of the roll of paper, improving the processing accuracy and quality of the product. Secondly, the whole process is an automated operation without manual intervention, improving the production efficiency;

[0035] The deviation-correcting feeding component is actually a hydraulic system, which can easily lift the roll paper tube for feeding when feeding a heavier or larger-diameter roll paper tube. At the same time, the deviation-correcting feeding component of the hydraulic system reduces impact and vibration, helps to protect the paper from damage, and improves the stability of the whole process.

[0036] Furthermore, as a preferred embodiment of the present invention but not a limitation, the monitoring device 11 includes a monitoring rod 111 arranged on the feed side of the tensioning mechanism 20, and the left and right ends of the monitoring rod 111 are provided with displacement sensors 112 for monitoring whether the roll paper is offset during loading, and the displacement sensor 112 is electrically connected to the correction device 12.

[0037] The equipment is pre-set to an initial position before operation. When the displacement sensor 112 detects that the roll paper deviates from the initial position during loading, it generates a deviation signal, causing the deviation correction device 12 to automatically correct the deviation.

[0038] In this embodiment, the displacement sensor can monitor the loading situation of the roll paper in real time. When deviation occurs, it can automatically trigger the correction device to make adjustments to avoid inaccurate cutting or waste due to the deviation of the roll paper loading. At the same time, continuous monitoring and immediate correction enhance the stability and reliability of production and reduce the downtime caused by the loading deviation problem.

[0039] Furthermore, as a preferred embodiment of the present invention but not a limitation, the feeding mechanism 10 also includes a rotating shaft 13 for rotating the paper roll for feeding and a feeding plate 14 for placing the paper roll at both ends of the rotating shaft 13. The feeding plates 14 at both ends are provided with a recessed portion 141 for mounting the paper roll shaft, and a damping bearing is provided between the feeding plate 14 and the rotating shaft 13.

[0040] In this embodiment, the recessed portion on the loading plate can firmly support the axis of the paper roll, ensuring that the paper roll remains stable during the rotation and loading process, avoiding paper deviation or damage caused by unstable support; at the same time, the recessed portion also helps to make the replacement of the paper roll more convenient, simplifying the loading operation and improving production efficiency.

[0041] Furthermore, as a preferred embodiment of this solution but not a limitation, the rotating shaft 13 is hinged to the hydraulic rod 1221 via a hinge 131 and is controlled by the hydraulic rod 1222. The rotating shaft 13 is also provided with a correction groove 132 for limiting the movement correction range of the correction feeding assembly 122.

[0042] Among them, the hydraulic cylinder 1222 controls the hydraulic rod 1221 to contract and drive the rotating shaft 13 to lift up, so that the paper roll can be lifted for loading; when loading is completed or the machine needs to be shut down for maintenance, the hydraulic cylinder 1222 controls the hydraulic rod 1221 to extend and drive the rotating shaft 13 to lower, so that the paper roll can be placed on the ground.

[0043] In this embodiment, the deviation correction groove can ensure that the deviation correction action is carried out within a predetermined range, thereby ensuring the accuracy of the adjustment of the paper roll feeding position; the hydraulic system controls the automatic feeding and material change of the paper roll cylinder, reducing the labor intensity of workers, improving work efficiency, and also helping to ensure the stability of the feeding process and reducing safety risks caused by improper manual operation.

[0044] Further, as a preferred implementation manner of this solution rather than a limitation, the feeding mechanism 10 is further provided with a feeding roller 15 for conveying the paper roll of the paper roll cylinder to the tensioning mechanism 20 and a first driving device 151 for controlling the rotation of the feeding roller 15. The first driving device 151 is a driving motor, a servo motor or a stepping motor.

[0045] In this embodiment, driving the feeding roller by a motor helps to ensure that the paper roll is fed at a constant speed and in a stable manner; the design of the feeding roller also helps to prevent paper wrinkles or excessive stretching during the feeding process.

[0046] Further, as a preferred implementation manner of this solution rather than a limitation, the tensioning mechanism 20 includes an upper tensioning roller 21, a lower tensioning roller 22 disposed below the upper tensioning roller 21, and a second driving device 23 for controlling the rotation of the upper tensioning roller 21 and the lower tensioning roller 22. The upper tensioning roller 21 and the lower tensioning roller 22 are connected by gear meshing. The upper tensioning roller 21 and the lower tensioning roller 22 are used to flatten the paper roll and increase the paper roll tension. The tensioning mechanism 20 further includes that the second driving device 23 is a driving motor, a servo motor or a stepping motor.

[0047] In this embodiment, the tensioning mechanism can effectively increase the tension of the paper roll, ensure that the paper roll remains flat and tight, and reduce the deviation and unevenness during the paper cutting process; the tensioning mechanism can also provide a stable and uniform tension for the paper roll during the conveying process, effectively preventing the deformation or damage of the paper roll during the conveying process, thereby reducing the waste rate.

[0048] Further, as a preferred implementation manner of this solution rather than a limitation, the conveying mechanism 30 includes a conveying component 31 and a guiding component 3' for guiding the paper roll to be conveyed to the punching mechanism for paper cutting. The conveying component includes a conveying roller 311 and a third driving device 312 for controlling the operation of the conveying roller 311 to convey the paper roll. The conveying roller 311 is connected by gear meshing with a pressing roller 313 for pressing the paper roll to increase the paper roll tension. The third driving device 312 is a driving motor, a servo motor or a stepping motor.

[0049] The guiding component 32 includes a guiding roller 321 and a mounting bracket 322 for mounting the guiding roller 321. First gears 323 are sleeved on both ends of the guiding roller 321. The first gears 323 rotate coaxially with the guiding roller 321. A fourth driving device 324 for controlling the rotation of the guiding roller 321 is provided on one side of the mounting bracket 322. A second gear 325 perpendicular to the first gear 323 is further provided on the mounting bracket 322. The fourth driving device 324 is a driving motor, a servo motor or a stepping motor.

[0050] In this embodiment, the conveying component can ensure that the toilet paper provides uniform force during the conveying process, realizes stable and continuous conveying, reduces the phenomenon of toilet paper slack or wrinkles, thereby reducing the rejection rate; the guiding component can ensure that the toilet paper is accurately conveyed to the punching mechanism, and avoids deviation or dislocation during the conveying process of the toilet paper.

[0051] The working principle of this embodiment is as follows:

[0052] An automatic deviation-correcting punching machine proposed by the present utility model can realize real-time monitoring of toilet paper during the feeding process of the toilet paper roll, and can automatically correct the deviation when deviation occurs, ensuring that the toilet paper can be accurately fed. The specific principle is as follows:

[0053] The axis of the toilet paper roll is erected on the recess 141 on the feeding plate 14 by a forklift or manually. The hydraulic rod 1221 is controlled by the hydraulic cylinder 1222 to retract, so as to lift the rotating shaft rod 13 upward, realizing the feeding of the toilet paper roll. The toilet paper is fed and conveyed to the tensioning mechanism 20 by the rotation of the feeding roller 15. During the feeding process, the displacement sensor 112 will monitor in real time whether the toilet paper deviates. When deviation occurs, the displacement sensor 112 will generate a deviation signal, causing the deviation-correcting motor 121 to control the left and right movement of the deviation-correcting feeding component 122 through the pulling member 123 to correct the deviation, thereby realizing the accurate feeding of the toilet paper roll.
