Description

Technical Field

[0001] This invention belongs to the field of ledger page cutting technology, specifically relating to an integrated fully automatic ledger page cutting device. Background Technology

[0002] The current sheet cutting technology in my country involves first dividing the raw material (roll material) into smaller rolls of the required width, then using a sheet-splitting machine to slit them into smaller rolls. This type of sheet-splitting machine requires one worker to operate each machine, and the slits are scattered, requiring manual sorting and stacking before packaging. Packaging workers then need to count each sheet individually, a process prone to errors that are difficult to detect early on. This process requires at least a dozen workers to meet production needs, resulting in high production costs. High costs and low profits are an undeniable fact in the industry. Furthermore, this method produces products with large dimensional errors and inconsistent sizes. This results in inconsistent product quality and an unattractive appearance after packaging. Furthermore, the blades on the current machines are not very durable and have strict requirements for blade engagement, necessitating frequent blade replacements. Accidents during blade replacement can easily lead to blade breakage, unintentionally increasing costs. Additionally, the existing machines generate significant dust and pollution during operation, causing considerable harm to workers' respiratory systems, with some even developing pneumoconiosis. Summary of the Invention

[0011] Preferably, a first feeding rubber shaft is movably mounted on the top of the base frame away from the feeding platform via a bearing, and a cutting feeding motor is mounted on the top of the base frame near the first feeding rubber shaft via a fixed seat. The output end of the cutting feeding motor is connected to the shaft drive of the first feeding rubber shaft via a coupling. A second feeding rubber shaft is movably mounted on the top of the base frame near the first feeding rubber shaft, and the second feeding rubber shaft is correspondingly arranged to the first feeding rubber shaft.

[0012] Preferably, two pressing cylinders are fixedly installed on the top of the base frame near the second feeding rubber shaft via a fixing bracket. The two pressing cylinders are symmetrically arranged, and the output ends of the two pressing cylinders are respectively connected to the two sides of the second feeding rubber shaft. A cutting bracket is fixedly installed on the top of the base frame near the second feeding rubber shaft, and a cross-cutting blade holder is movably installed on one side of the cutting bracket via a slide rail.

[0013] Preferably, two synchronous pulleys are symmetrically installed at the top of the cutting bracket, and the two synchronous pulleys are connected by a synchronous belt drive. A cross-cutting motor is installed on the side of the cutting bracket near the synchronous pulleys by a fixed seat, and the output end of the cross-cutting motor is connected to the shaft of the synchronous pulleys by a coupling.

[0014] Preferably, the cross-cutting blade holder is fixedly connected to one side of the timing belt, a cross-cutting rod is fixedly installed on one side of the cross-cutting blade holder, and a cross-cutting blade is movably installed at one end of the cross-cutting rod via a bearing.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This invention places an infrared photoelectric automatic correction device on the feeding platform, then places the abrasive cloth roll onto the device, and guides it to the feeding structure above the base frame. The feeding structure pulls the abrasive cloth roll to unwind it. As the roll passes the lower cutting shaft, a cutting cylinder pushes the cutting wheel closer to the roll, thus cutting it into strips during unwinding. The strips, under the action of the first and second feeding shafts, reach the bottom of the cross-cutting blade holder. At this point, the cross-cutting blade holder moves back and forth under the action of the synchronous belt, synchronously driving the cross-cutting blade to move, thereby achieving the winding of the strips of abrasive cloth. The device performs a single horizontal cut, ultimately slicing the abrasive cloth into blocks. The cut blocks fall onto a conveyor belt, and after each layer of abrasive cloth is cut, the swing frame swings to one side at a certain angle, then travels a distance to ensure the orderly transport of the cut materials to the rear. This device integrates slitting, cutting, and stacking, effectively improving work efficiency, saving operators, reducing costs, minimizing cutting errors, ensuring consistent dimensions, and guaranteeing product quality. Mechanized slitting and cutting not only offers high efficiency and speed but also optimizes the working environment, eliminating dust and ensuring the quality and effectiveness of the cut sheets, thus meeting industry demands.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0026] Example 1:

[0027] Please see Figure 1 - Figure 3 As shown, an integrated fully automatic ledger page cutting device includes:

[0028] Base frame 1, with a material feeding platform 11 fixedly installed on one side of the base frame 1;

[0029] Slitting assembly 2, the slitting assembly 2 is set on the side of the base frame 1 near the feeding platform 11, the slitting assembly 2 includes a slitting bracket 21 fixedly installed at the top of the base frame 1, a plurality of blade holder plates 22 are fixedly installed on one side of the slitting bracket 21, a blade wheel 25 is movably installed on one side of the blade holder plate 22, and a lower blade shaft 26 is movably installed on the side of the base frame 1 near the slitting bracket 21.

[0030] The cutting assembly 3 is located on the side of the slitting bracket 21 away from the feeding platform 11. The cutting assembly 3 includes a first feeding rubber shaft 31 movably installed on one side of the base frame 1, a second feeding rubber shaft 33 movably installed on one side of the first feeding rubber shaft 31, a cutting bracket 35 fixedly installed on the side of the base frame 1 near the second feeding rubber shaft 33, a cross-cutting blade holder 36 movably installed on one side of the cutting bracket 35 via a slide rail, and a cross-cutting blade 310 movably installed on one side of the cross-cutting blade holder 36.

[0031] Stacking assembly 4 is located on the side of the base frame 1 near the cross-cutting knife holder 36. Stacking assembly 4 includes a conveying bracket 41. A swing frame 42 is movably installed on the top of the conveying bracket 41. A power shaft 43 is movably installed on one side of the swing frame 42. An auxiliary shaft 44 is movably installed on one side of the swing frame 42. Chain frames 46 are symmetrically installed on both sides of the conveying bracket 41.

[0032] Specifically, a slitting bracket 21 is fixedly installed on the top of the base frame 1 near the feeding platform 11. Several blade holder plates 22 are fixedly installed on one side of the slitting bracket 21. A cutting cylinder 23 is fixedly installed on one side of the blade holder plate 22. A connecting bar 24 is fixedly installed at the output end of the cutting cylinder 23. A blade wheel 25 is movably installed on the end of the connecting bar 24 away from the cutting cylinder 23 via a bearing. A lower blade shaft 26 is movably installed on the side of the base frame 1 near the slitting bracket 21 via a bearing.

[0033] As can be seen from the above, the feeding platform 11 is used to feed the abrasive cloth roll, which can be placed into the infrared photoelectric automatic correction device (the infrared photoelectric correction device is a device that uses an electric pusher to adjust the left and right swing direction and distance of the abrasive cloth roll based on infrared photoelectric sensing; this part is existing technology and will not be described in detail here). The top of the base frame 1 is equipped with a feeding structure (composed of several rotating rollers, mainly for conveying the abrasive cloth roll). The cutting cylinder 23 provides power output for the up and down movement of the cutter wheel 25. The lower cutter shaft 26 uses a mold steel sleeve, which is wear-resistant and durable.

[0034] In actual use, the feeding structure pulls the abrasive cloth roll to unwind. When the abrasive cloth roll passes the lower cutter shaft 26, the strip cutting cylinder 23 pushes the cutter wheel 25 close to the abrasive cloth roll, so that the abrasive cloth roll will be cut into strips during the unwinding process.

[0035] Example 2:

[0036] Please see Figure 1 and Figure 4 - Figure 5 As shown, a first feeding rubber shaft 31 is movably mounted on the top of the base frame 1 away from the feeding platform 11 via a bearing. A cutting feeding motor 32 is mounted on the side of the base frame 1 close to the first feeding rubber shaft 31 via a fixed seat. The output end of the cutting feeding motor 32 is connected to the shaft drive of the first feeding rubber shaft 31 via a coupling. A second feeding rubber shaft 33 is movably mounted on the top of the base frame 1 close to the first feeding rubber shaft 31. The second feeding rubber shaft 33 is correspondingly arranged with the first feeding rubber shaft 31.

[0037] Specifically, two pressing cylinders 34 are fixedly installed on the top of the base frame 1 near the second feeding rubber shaft 33 via a fixing bracket. The two pressing cylinders 34 are symmetrically arranged, and their output ends are respectively connected to the two sides of the second feeding rubber shaft 33. A cutting bracket 35 is fixedly installed on the top of the base frame 1 near the second feeding rubber shaft 33. A cross-cutting blade holder 36 is movably installed on one side of the cutting bracket 35 via a slide rail.

[0038] As can be seen from the above, the cutting and feeding motor 32 provides power output for the rotation of the first feeding rubber shaft 31, and the pressing cylinder 34 can drive the second feeding rubber shaft 33 to move up and down. The two ends of the second feeding rubber shaft 33 are equipped with connecting blocks through bearings, and the pressing cylinder 34 is fixedly connected to the connecting blocks. In this way, the second feeding rubber shaft 33 can be driven to move closer to or away from the first feeding rubber shaft 31. When the strip-shaped abrasive cloth reaches between the first feeding rubber shaft 31 and the second feeding rubber shaft 33, the pressing cylinder 34 pushes the second feeding rubber shaft 33 to press the top of the abrasive cloth. In this way, the strip-shaped abrasive cloth can be stably conveyed to the bottom of the cutting bracket 35, and then the cutting operation is performed.

[0039] Specifically, two synchronous pulleys 37 are symmetrically installed at the top of the cutting bracket 35. The two synchronous pulleys 37 are connected by a synchronous belt drive. A cross-cutting motor 38 is installed on the side of the cutting bracket 35 near the synchronous pulleys 37 via a fixed base. The output end of the cross-cutting motor 38 is connected to the shaft of the synchronous pulleys 37 via a coupling. The cross-cutting blade holder 36 is fixedly connected to one side of the synchronous belt. A cross-cutting rod 39 is fixedly installed on one side of the cross-cutting blade holder 36. A cross-cutting blade 310 is movably installed at one end of the cross-cutting rod 39 via a bearing.

[0040] As can be seen from the above, a timing belt (not shown in the figure) is connected between the two timing pulleys 37. The timing belt is fixedly connected to one side of the cross-cutting blade holder 36. When the cross-cutting motor 38 drives one of the timing pulleys 37 to rotate, it will synchronously drive the cross-cutting blade holder 36 to move through the timing belt, thereby driving the cross-cutting blade 310 to move and realize the cutting operation.

[0041] In actual use, the strip-shaped abrasive cloth roll is brought to the bottom of the cross-cutting blade holder 36 by the action of the first feeding rubber shaft 31 and the second feeding rubber shaft 33. At this time, the cross-cutting blade holder 36 moves back and forth under the action of the synchronous belt, and synchronously drives the cross-cutting blade 310 to move, thereby realizing the further cross-cutting of the strip-shaped abrasive cloth roll, and finally cutting it into blocks. The blocks of abrasive cloth will fall onto the conveyor belt (not shown in the figure).

[0042] Example 3:

[0043] Please see Figure 1As shown, a conveyor bracket 41 is fixedly installed on the side of the base frame 1 near the cross-cutting blade holder 36. A swing frame 42 is movably installed on the top of the conveyor bracket 41 via a bearing. A power shaft 43 is movably installed on one side of the swing frame 42 via a bearing. An auxiliary shaft 44 is movably installed on the side of the swing frame 42 away from the power shaft 43 via a bearing. The power shaft 43 and the auxiliary shaft 44 are connected by a conveyor belt.

[0044] Specifically, a transmission motor 45 is mounted on the side of the swing frame 42 near the power shaft 43 via a fixed base. The output end of the transmission motor 45 is connected to the shaft of the power shaft 43 via a coupling. Chain frames 46 are symmetrically mounted on both sides of the transmission bracket 41.

[0045] As can be seen from the above, the side of the swing frame 42 away from the cutting bracket 35 is movably mounted inside the conveyor bracket 41 through a bearing. The power shaft 43 and the auxiliary shaft 44 are connected to the conveyor belt (not shown in the figure), and the conveyor motor 45 provides power output for the rotation of the power shaft 43, thereby driving the material above the conveyor belt to move. The chain frame 46 is equipped with a sprocket and chain structure (not shown in the figure). The chain drive is provided by a servo motor (not shown in the figure), and a rotating shaft and other structures are movably connected between the chain and the swing frame 42. In this way, when the chain is driven, it will drive the swing frame 42 to swing up and down to a certain extent, thereby realizing the lifting function of one side of the conveyor belt.

[0046] In practical use, adjust the conveyor belt height to be close to the cross-cutting blade holder 36 to catch the blocks of sandpaper. After it's full, lower the conveyor belt a certain distance to catch the next layer of material. Once full, move the conveyor belt backward a short distance while continuing to catch material. For example, if we're cutting 120x230 sheet sandpaper, requiring 100 sheets per pack, each sheet 2mm thick, we can set it so that the conveyor belt lowers 2mm after each cut by the cross-cutting blade 310, and the servo motor moves the conveyor belt once every 100 cuts. This perfectly cuts stacks of 100 sheet sandpaper, and the worker only needs to organize and package them behind the conveyor belt; there's no need to count the quantity anymore.

[0047] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
