In addition, the terms such as "upper", "lower", "left", "right" and "middle" used in the present specification are for clarity of description, and are not intended to limit the scope of the present invention, and changes or modifications of the relative relationship may be made without substantial technical changes.

As shown in fig. 1 to 3, the present invention provides an automatic cutting device, which includes a feeding module 2, a conveying module 3, a cutting module 4 and a control module 6; the feeding module 2 comprises a base 21 for fixing the object 1 to be cut and a first driving device 22 for driving the object 1 to be cut to rotate so as to feed; the conveying module 3 is arranged adjacent to the feeding module 2, the conveying module 3 comprises a plurality of conveying rollers 31 arranged in parallel and a second driving device connected with the plurality of conveying rollers 31, and the second driving device is used for conveying the object to be cut 1 to the cutting module 4; the cutting module 4 is positioned at one end of the conveying module 3 far away from the feeding module 2 and is used for cutting the object 1 to be cut conveyed by the conveying module 3; the cutting module 4 comprises a fixed cutter 41, a movable cutter 42 and a third driving device 43 connected with the movable cutter 42, wherein the fixed cutter 41 corresponds to the movable cutter 42 up and down; the control module 6 is connected to the first driving device 22, the second driving device and the third driving device 43. The automatic cutting equipment can realize automatic feeding, automatic conveying and automatic cutting of the object 1 to be cut, greatly reduce the labor cost, improve the production efficiency and simultaneously avoid dangers that the cutting specification is not satisfactory and personnel injury is easy to cause in the manual cutting process. Fig. 1 generally shows the modular construction of the automatic cutting apparatus of the present invention, and fig. 2 shows the specific structure of each module in more detail.

As an example, the object 1 to be cut is various soft objects wound into a roll, such as a core roll used by the inventor in a steel plant for packaging steel, and other materials such as a cloth roll in a clothing factory and a separator roll in a battery plant can be cut by the automatic cutting apparatus of the present invention. What is important is that the object 1 to be cut is wound into a roll to form a roll core, so that the roll core can be fixed on the machine base 21 and can be continuously unreeled in the automatic cutting process to discharge the object 1 to be cut.

The specific shape of the base 21 can be designed according to the needs. For example, in the present embodiment, the machine base 21 includes a roller shaft 211 and a bearing seat 212, two ends of the roller shaft 211 are erected on the bearing seat 212, the roller shaft 211 is connected to the first driving device 22, and the object 1 to be cut is placed on the roller shaft 211, so that the roller shaft 211 is driven to rotate by the first driving device 22 to drive the object 1 to be cut to rotate. The number of the roller shafts 211 may be 2 or more than 2, so as to simultaneously place a plurality of objects to be cut 1 (generally, only one object to be cut can be cut at a time in cutting), and the specifications of the plurality of objects to be cut 1 may be the same or different. Of course, if the object 1 to be cut has a reel, the object 1 to be cut can be directly fixed on the carrying seat 212 by mounting the reel on the carrying seat 212 (in this case, the machine base 21 is equivalent to the carrying seat 212). The bearing seat 212 may be a structure including 2 parallel baffles, and the two baffles are connected by a bottom plate at the bottom to fix the bearing seat 212. It should be noted that the carrying seats 212 may be located only on the periphery of the feeding module 2, or may extend all the way to the periphery of the conveying module 3 and the cutting module 4 to fix the entire automatic cutting device, as shown in fig. 1 and 2, for example. The length of the baffle and the distance between the two baffles can be set as desired, for example, according to the width of the object 1 to be cut and the radial length of the reel, in this example the length of the baffle is 2.5 meters (extending from the feed module 2 up to the cutting module 4), the maximum height is 1.5 meters and the width is 2.1 meters. Of course, the bearing seat 212 may also be in other structures, for example, the bearing seat may be only located at two sides of the feeding module 2 area, and each module may be independent from each other and fixed by an appropriate manner, which is not strictly limited in this embodiment. In order to prevent the roller shaft 211 from falling off the carrier base 212 during the cutting operation, a protection device such as a sleeve (not shown) may be provided at both ends of the roller shaft 211, and the sleeve may contact the surface of the carrier base 212 away from the object 1 to be cut.

It should be noted that the first driving device 22 and the second driving device are defined in the present invention for convenience of description, but the first driving device 22 and the second driving device may be the same driving unit or different driving units. From the viewpoint of cost, it is preferable that both of them are the same unit, for example, the same motor, more specifically, a servo motor, and the same motor is used for the first driving device 22 and the second driving device, so that the synchronization of feeding and transferring can be maintained, and the second driving device can be provided on each side of the transfer roller 31 to improve the smoothness during the transfer.

The number of the conveying rollers 31 of the conveying module 3 and the distance between different conveying rollers 31 may be different according to different requirements, for example, according to the material hardness and the cutting length of the object 1 to be cut, for example, if the hardness of the object 1 to be cut is relatively large, the distance between different conveying rollers 31 may be set to be slightly large (for example, between 5 and 10 cm), and if the material of the object 1 to be cut is relatively soft, the distance is relatively small (for example, less than 5 cm). Each of the conveying rollers 31 can be theoretically driven by an independent motor, but in the present embodiment, all the conveying rollers 31 are driven by the same second driving device in view of cost and structural simplification. And for the drive, conveying module 3 further still includes conveyer belt 33, conveyer belt 33 cover is located the both ends of a plurality of transfer rollers 31, can also set up transfer roller safety guard 34 in addition, transfer roller safety guard 34 cover is located the periphery of conveyer belt 33 to avoid conveyer belt 33 to drop in transportation.

As an example, the automatic cutting device further comprises a pressing module 5, wherein the pressing module 5 is located above the conveying roller 31 and is used for pressing the object 1 to be cut so as to avoid the object 1 to be cut from generating wrinkles in the conveying process and even being extruded upwards to cause the device to be stuck and other faults. The specific structure of the pressing module 5 may be set as required, for example, it may be a flat plate structure having a horizontal plane, or may be a structure including a plurality of pressing rollers 51 and a pressing frame 52 connected to the plurality of pressing rollers 51 as shown in this embodiment, where the pressing frame 52 is used to support and fix the pressing rollers 51. The different intervals between the pressing rollers 51 and the number of the pressing rollers 51 can also be set according to the material hardness and the cutting length of the object 1 to be cut, and the pressing rollers 51 are preferably arranged in parallel at intervals. The horizontal area of the pressing module 5 may be the same as the horizontal area of the transfer module 3, or may be smaller than the horizontal area of the transfer module 3. When the horizontal area of the pressing module 5 is smaller than the horizontal area of the conveying module 3, the pressing module 5 is preferably located above the conveying module 3 close to the cutting module 4, so as to ensure that the object 1 to be cut entering the cutting module 4 is not warped or piled. The pressing roller 51 and the transfer roller 31 are preferably staggered up and down to avoid marking the cut product due to excessive local pressing force on the object 1 to be cut. The pressing module 5 can adjust the pressing pressure by moving up and down, such as the pressing roller 51 can move up and down on the pressing frame 52, more specifically, such as installing through holes arranged in different height directions of the pressing frame 52, the pressing force is adjusted by changing the installation position of the pressing roller 51 on the pressing frame 52 to adjust the distance between the pressing roller 51 and the conveying roller 31 in the vertical direction, or a fixing frame (not shown in the figure, or an extension of the aforementioned bearing seat 212) connected to the pressing frame 52 is provided to mount the conveying module 3 on the fixing frame, the position of the pressing module 5 on the fixing frame is adjusted as needed to adjust the distance between the pressing roller 51 and the conveying roller 31 in the vertical direction, which is not strictly limited in this embodiment.

As an example, the automatic cutting device also comprises a support roller 7 positioned between the feeding module 2 and the pressing module 5, the height of the support roller 7 is higher than that of the pressing roller 51, and the object 1 to be cut is placed on the support roller 7 and then stretched on the conveying module 3. The supporting roller 7 is preferably located on the bearing seat 212, so that the warping of the object 1 to be cut can be further avoided, the phenomenon that the equipment is clamped due to material overstocking and curling at the outlet of the feeding module 2 is avoided, and meanwhile, the fixing of the bearing seat 212 can be strengthened through the supporting roller 7. The number of the support rollers 7 may be one or more, and when the number of the support rollers 7 is plural, the heights of the plural support rollers 7 may be the same or different.

As an example, the automatic cutting device further includes a limit adjusting module 9 located between the feeding module 2 and the conveying module 3, the limit adjusting module 9 includes a limit adjusting rod 91 and a plurality of limit adjusting wheels 92 located on the limit adjusting rod 91, and the limit adjusting wheels 92 can move on the limit adjusting rod 91 to define a corresponding space for the object 1 to be cut to pass through according to the width of the object 1 to be cut. The number of the limit adjusting rods 91 may be plural, when the number of the limit adjusting rods 91 is plural, the plural limit adjusting rods 91 are arranged in parallel at intervals, the number of the limit adjusting wheels 92 on a single limit adjusting rod 91 is more than 2, and preferably is an even number, such as 2, 4 or more, and the number of the limit adjusting wheels 92 on a single side of a single limit adjusting rod 91 is one or 2. The distance between the single limit adjusting rod 91 and the limit adjusting wheels 92 on the two sides is the cutting width of the object 1 to be cut. Specifically, the limit adjusting wheel 92 may be provided with a groove (not shown), the length direction of the groove is consistent with the conveying direction of the object 1 to be cut, when the object 1 to be cut passes through the limit adjusting module 9, two sides of the object 1 to be cut are embedded into the groove, and thus the edge of the object 1 to be cut may be prevented from warping.

As an example, the automatic cutting device further includes an outfeed guide plate 8 disposed adjacent to the cutting module 4, where the outfeed guide plate 8 has an inclined slope surface, and the height of the inclined slope surface gradually decreases along a direction away from the cutting module 4, and is used for outputting a cut object 11 obtained after being cut by the cutting module 4. The discharging guide plate 8 may be separately disposed, for example, may be an independent structure, and is disposed at the discharging position of the automatic cutting apparatus as needed (and may be removed when not needed), or may be a part of the fixed frame of the automatic cutting apparatus (such as a part of the bottom plate mentioned in the foregoing description of the carrying seat 212), and the inclination angle of the inclined slope (the included angle between the bottom surface and the horizontal plane) may be 15-60 °, and a receiving trough (not shown) may be further disposed. When the automatic cutting equipment is placed at a certain height, the material receiving groove can be positioned at the oblique lower part of the discharging guide plate 8, and a cut object 11 obtained after cutting slides into the discharging groove through the oblique slope surface of the discharging guide plate 8, so that automatic material receiving is realized.

As an example, the cutting module 4 further comprises a knife seat 44, the knife seat 44 comprises a base 441 and a hollow frame 442 arranged on the base 441 (the base 441 may be a part of the bottom plate mentioned in the description of the carrying seat 212), and a guide rail 443 is arranged on a side wall of the hollow frame 442; the fixed knife 41 is disposed on the base 441, one end of the movable knife 42 is connected to the fixed knife 41, and the other end is located in the guide rail 443, during cutting, the movable knife 42 is driven by the third driving device 43 to move along the guide rail 443 to contact with the fixed knife 41, that is, the object 1 to be cut is cut like a pair of scissors. The third driving device 43 may include a lifting cylinder, and a variable speed motor or the like connected to the movable cutter 42 may be further provided to adjust the cutting speed as needed. Of course, in other examples, the movable knife 42 is attached to the fixed knife 41 and can slide along the width direction of the object 1 to be cut to achieve cutting, and the present embodiment is not limited thereto.

By way of example, the control module 6 includes a central controller, such as a computer host, and more particularly, may be a central controller with a touch screen to facilitate operation and monitoring by a worker.
