Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of paper cutting machine tray replacement, and particularly relates to a paper cutting machine provided with an automatic tray replacement structure and an operation method thereof. BACKGROUND

[0002] The paper cutting machine is used to process the paper cutting demand in the late printing stage. In the cutting process, a user needs to stack the paper to a certain thickness and arrange the paper in a flat manner, then manually lifts the paper stack and places it on the worktable of the machine, and after the cutter is pressed to cut, the user pauses the cutting work, arranges the paper in a flat manner and sends the paper out of the machine. The whole process needs the user to manually lift and place, and the cutting work needs to be paused, which consumes a lot of time and reduces the cutting efficiency. The paper cutting machine generally adopts a chain transmission mode in the paper pushing structure, that is, an external servo motor cooperates with a chain to drive the transmission structure inside the machine to complete the paper pushing work. However, due to the difference in the machine model, the number of transmission structures (for example, the number of gears) is also large, and the length of the chain also needs to be lengthened, which requires a "tensioner" to be set for adjustment. However, the tensioner structure on the machine is generally simple, and there is a limitation in the installation space. The user often adjusts the work by hand feeling, and there is a large adjustment error. The tightness of the chain is difficult to control, which makes it difficult for the transmission structure to complete the pushing work completely and smoothly, resulting in errors in the cutting size of the paper and affecting the quality of the cut paper.

[0013] The operation method of the paper cutting machine with the automatic tray changing structure is as follows:

[0014] Step one,

[0015] Check whether the insulation of the machine circuit and the motor is normal and whether the power supply is normal, and start the machine after confirming that the machine circuit and the motor are normal and the power supply is normal.

[0016] Check whether the cutting knife blade is damaged or dull, and start the machine after confirming that the cutting knife blade is sharp.

[0019] Clean the workbench before starting the machine, and do not place other sundries to prevent the machine from being damaged.

[0020] Step two, turn on the power supply and wait for the equipment initialization, and observe whether the equipment runs normally.

[0021] Step three, after the machine runs normally, the user places the tray one with the paper to the left side of the conveying mechanism, and then the conveying mechanism conveys to the right side, that is, to the rear of the machine.

[0022] Step four, when the tray one is conveyed to the position of the lifting mechanism, the tray one will move to the inner side of the lifting mechanism under the pushing of the conveying mechanism, so that the frame of the lifting mechanism does not touch the tray one, and thus the tray one can smoothly enter the inner side of the lifting mechanism under the conveying of the conveying mechanism, and when the machine detects that the tray one completely enters the inner side of the lifting mechanism, the lifting motor can be controlled to work to lift the lifting mechanism, so as to lift the tray one.

[0023] Step five, after tray one enters the inner side of the lifting mechanism, the lifting motor starts to work to drive chain one to lift the lifting mechanism upward, so that the tray one with paper is also lifted upward, when the tray one is lifted to the appropriate height, the user closes the lifting motor, and the tray is positioned at the current height, at this time the user can control the control mechanism and the cutting mechanism to move and cut the paper by operating the control end;

[0024] Step six, the user operates the control end, the control end controls the control mechanism and the cutting mechanism to move left and right on the equipment mounting frame under the cooperation of the toothed plate, wherein the control mechanism can detect whether the paper is damaged and other data during the movement, and measure the cutting size required by the paper, and then the control mechanism controls the cutting mechanism and the cutting knife to cut the paper on the tray one;

[0025] Step seven, after the paper on the tray one is cut, the user operates the control end to "release" chain one, so as to lower the lifting mechanism and place the tray one on the conveying mechanism, at this time, after the tray one is placed on the conveying mechanism, the lifting mechanism continues to descend a little height, so that the frame of the lifting mechanism is separated from the edge of the tray one, so that the convex bottom of the tray one can pass through the inner side of the lifting mechanism, so that the tray one and the paper on the tray one can be sent to the rear of the machine under the conveying of the conveying mechanism, which is convenient for workers to pack and transport, it should be noted that while conveying the tray one, the new tray one with paper is placed from the input side of the conveying mechanism, that is, the left side of the conveying mechanism, and then conveyed to the position of the lifting mechanism, and then enters the inner side of the lifting mechanism and is lifted by chain one to the normal cutting position, at this time, the lowered tray one, that is, tray two, is sent to the rear of the machine for workers to pack, wherein the lowered and sent tray one is tray two, so that under the continuous circulation of the tray one and the tray two, continuous feeding, continuous cutting and continuous discharging can be realized, which can save time, improve production efficiency and improve production safety.

[0026] In summary, the beneficial effects of the present application are:

[0027] 1. The application adopts the feeding mode of lifting, and cooperates with the feeding of the two trays in circulation, the working mode of discharging, when the tray two and the cut paper on the tray two are lowered, the tray two is conveyed to the rear of the machine by the conveying mechanism, then it is packaged and transported by the worker, then the tray one is put into the lifting platform from the input side of the conveying mechanism and sent to the normal paper receiving position, so that the time can be saved, the production efficiency can be improved, and the production safety can be ensured, and the tightness of the chain can be adjusted by the impact sound generated by the swing piece and the matching gear, so that the user can know the current tightness of the chain, the gears on the equipment can rotate smoothly, the paper can be pushed smoothly, and the quality of the paper cutting can be ensured.

[0028] 2. The conveying mechanism, chain two, a plurality of conveying rollers, transmission gears and auxiliary gears can form a power transmission structure with a length meeting the working requirements, so that a conveying device can be formed by cooperating with the base frame and the mounting frame, and the conveying of the product can be realized, in the design of the scheme, the conveying mechanism can realize feeding and discharging at the same time, and the feeding and discharging functions are integrated, compared with the traditional feeding equipment and the discharging equipment in the form of independent, the equipment cost can be reduced, the steps of material transfer can be reduced, and the production efficiency can be improved.

[0029] 3. The step motor two is used as a driving device to drive the conveying mechanism to work and convey the product, and it should be noted that the step motor two is prior art, the output gear and one of the transmission gears are connected by a chain, the protective cover is arranged on the output gear and one of the transmission gears, the output gear can be protected, the chain in this section can also be protected, the service life is prolonged, and the user can be prevented from being injured, and the working safety is improved.

[0030] 4. The step motor one drives the gear one to rotate, the gear one is engaged with the toothed plate, and the toothed plate is fixed on the equipment mounting frame, so that the equipment mounting frame can roll on the toothed plate when rotating, so as to drive the whole cutting mechanism to move, adjust the cutting position of the cutting knife, improve the accuracy of paper cutting, and start the equipment, push the cylinder to work, when the output end of the push cylinder extends, that is, when it moves downward, the sliding piece moves downward in the inner cavity of the sliding groove, and the sliding piece moves downward, so as to cut the paper on the tray one.

[0031] 5. Through the setting of the control mechanism, the stepper motor two installed on the sliding housing two will drive the gear two to rotate. The gear two meshes with the toothed plate, which is fixed on the equipment mounting frame. When the gear two rotates, it will roll on the toothed plate, thereby driving the entire control mechanism to move. The control device can detect the moving distance of the cutting mechanism to detect the cutting size of the paper, for example, by using infrared detection or other methods to meet processing requirements.

[0032] 6. This invention, through the design of the lifting mechanism, allows the pallet to enter the inner side of the lifting mechanism. Since two horizontal support plates and two vertical support rods are assembled into a rectangular frame, both the front and rear sides of the rectangular frame are open, allowing the pallet to enter and exit. The two horizontally placed vertical support rods are located above the two horizontal support plates, with a certain distance between them. This creates an inlet and outlet on the front and rear sides of the rectangular frame, ensuring that the two vertical support rods do not obstruct the pallet's entry and exit. Simultaneously, a portion of the two horizontal support plates extends from opposite sides, matching the outward-extending edge of the pallet, thus lifting it. Since the overall thickness of the pallet is greater than the overall thickness of the lifting mechanism, the bottom of the pallet can extend beyond the inner side of the lifting mechanism. The lifting mechanism can then detach from the pallet by continuing to lower it, allowing the pallet to leave the inner side of the lifting mechanism under the conveyor rollers. It should be noted that when the lifting mechanism "peels" the pallet, the lowering height of the lifting mechanism must avoid the vertical support rods obstructing the pallet, ensuring the pallet can be moved out smoothly.

[0033] 7. Through the adjustment mechanism, the positioning plate and tensioning wheel can rotate together on the fixed shaft. The fixed shaft is installed in an "eccentric" manner, so the tensioning wheel can support and tension the chain. It can tighten the chain when it becomes loose, ensuring that the chain is always engaged with the lifting gear 1, lifting gear 2, and lifting gear 3 during operation, thus ensuring normal power transmission. It should be noted that when the tensioning wheel rotates, it also drives the positioning plate to rotate. Then, with the help of the positioning bolts, the positioning plate is positioned on the fixed plate, which ensures the stability of the tensioning wheel.

[0034] 8、The present application is through the setting of limiting assembly, when the tensioning wheel rotates, the matching gear is not rotating, the swing piece, the fixed sleeve, the sliding sleeve two and the spring will rotate with the tensioning wheel, when the tensioning wheel rotates, the swing piece will be first pressed by the matching gear, then the swing piece will rotate, it is need to point out that, the shape and structure of the swing piece can be modified according to actual conditions without affecting the rotation and the rotation of the matching gear, when the swing piece is pressed and rotated, the matching gear will also slide into the fixed sleeve, and the spring will also be compressed, when the swing piece "overcomes" a tooth, the sliding sleeve two will pop out of the inner cavity of the fixed sleeve under the action of the spring, so as to push the swing piece back to the original position, then one end of the swing piece will be clamped into the tooth on the matching gear again, at this time, sound will be produced to prompt the user to rotate the angle of the tensioning wheel, so that the user can accurately control the rotation angle of the tensioning wheel, and provide convenience for the work of the user, it is need to point out that, sound will be produced when the swing piece "overcomes" a tooth.

DETAILED DESCRIPTION

[0051] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings. Figures 1-14 The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings. EMBODIMENT

[0052] The utility model provides a paper cutting machine with automatic tray changing structure, including conveying mechanism 1, drive mechanism 2 is fixedly installed to the left side of conveying mechanism 1, the top of conveying mechanism 1 one side is fixedly installed with equipment mounting bracket 3, the equipment mounting bracket 3 one side is fixedly installed with gantry 8 that erects on conveying mechanism 1, the top of equipment mounting bracket 3 one side is fixedly installed with toothed plate 4, the top of equipment mounting bracket 3 is successively movably installed with control mechanism 6 and cutting mechanism 5 from left to right, control mechanism 6 and cutting mechanism 5 all are with toothed plate 4 is adapted, cutting mechanism 5 one side detachably installs cutting knife 7, the surface of gantry 8 is slidably installed with lifting mechanism 9, the inner side of lifting mechanism 9 is placed with tray no.

[0053] The specific use process is as follows: when working, the user turns on the switch to power on the device, and after power on, the driving mechanism 2, the cutting mechanism 5, the control mechanism 6 and the lifting motor 11 can start working at any time, which is the prior art; when working, the device starts, and the driving mechanism 2, the cutting mechanism 5, the control mechanism 6 and the lifting motor 11 also start working; specifically, after the stepping motor two 22 works, it drives the output gear 23 to rotate, because the output gear 23 is connected with the transmission gear 105 and the auxiliary gear 106 by chain transmission, so the output gear 23 will first drive the transmission gear 105 closest to the stepping motor two 22 to rotate, so the chain adapted will also follow the movement, then the chain will drive other transmission gears 105 and auxiliary gears 106 to rotate, with the transmission of power, finally all the transmission gears 105 and auxiliary gears 106 will rotate, then all the transmission gears 105 will drive the corresponding conveying drum 104 to rotate, so the whole conveying mechanism 1 can realize conveying work; it should be noted that the user adjusts the layout of chain two according to the actual situation, which can meet the normal and smooth transmission of power;

[0054] Then the user will put the tray one 10 with paper from the input side of the conveying mechanism 1, that is, the left side, and then under the transmission of the multiple rolling conveying rollers 104, the tray one 10 will move to the direction of the lifting mechanism 9 and then enter the inside of the lifting mechanism 9. Because the two horizontal supporting plates 91 and the two vertical supporting rods 92 are assembled into a rectangular frame, the front and back sides of the rectangular frame are open to allow the tray one 10 to enter and exit, the two horizontally placed vertical supporting rods 92 are located above the two horizontal supporting plates 91, and there is a certain gap between the horizontal supporting plates 91 and the vertical supporting rods 92. In this way, the entrance and exit are formed on the front and back sides of the rectangular frame, so that the two vertical supporting rods 92 do not block the entry and exit of the tray one 10. At the same time, the opposite side of the two horizontal supporting plates 91 also extends a part, which can match the outwardly extending edge of the tray one 10 and can lift the tray one 10. At the same time, the overall thickness of the tray one 10 is greater than the overall thickness of the lifting mechanism 9, so the bottom of the tray one 10 can extend out of the inside of the lifting mechanism 9. In this way, the lifting mechanism 9 can be separated from the tray one 10 by continuing to lower, so that the tray one 10 can leave the inside of the lifting mechanism 9 under the transmission of the conveying rollers 104. It should be noted that when the lifting mechanism 9 "strips" the tray one 10, the lowering height of the lifting mechanism 9 should avoid blocking the tray one 10, so that the tray one 10 can be smoothly removed. In this way, the lifting of the tray one 10 does not require manual intervention and can achieve automatic lifting, providing convenience for the user's cutting work and improving cutting efficiency. Then, when the tray one 10 enters the inside of the lifting mechanism 9, the lifting motor 11 starts to work, driving the gear four to rotate. Because the lifting gear one 12, the lifting gear two 13, the lifting gear three 14, and the gear four are connected by the chain one 16, the gear four will first drive the lifting gear three 14 to rotate, then drive the lifting gear two 13 to rotate, and then drive the lifting gear one 12 to rotate, and finally lift the lifting mechanism 9 up. It should be noted that the user adjusts the layout of the chain one 16 according to the actual situation to ensure normal and smooth power transmission. With the upward pulling of the chain one 16, the lifting mechanism 9 will be lifted up, and the tray one 10 will also move up. When the tray one 10 is lifted to the appropriate height, the lifting is stopped and the tray one 10 is positioned at the current height. This is the prior art. Then the user controls the cutting mechanism 5 and the control mechanism 6 to move on the equipment mounting rack 3 in cooperation with the use of the tooth plate 4. Specifically, the stepping motor two installed on the sliding housing two 61 drives the gear two 62 to rotate. The gear two 62 is engaged with the tooth plate 4, which is fixed on the equipment mounting rack 3. In this way, when the gear two 62 rotates, it will roll on the tooth plate 4, thereby driving the entire control mechanism 6 to move. The control device 63 can detect the movement distance of the cutting mechanism 5 to detect the cutting size of the paper, for example, by using infrared detection or other methods that meet the processing requirements. This is the prior art, which will not be described in detail in this document.When the step motor 52 works, it drives the gear 53 to rotate, the gear 53 is engaged with the toothed plate 4, and the toothed plate 4 is fixed on the equipment mounting frame 3, so that the equipment mounting frame 3 can roll on the toothed plate 4 when rotating, thereby driving the whole cutting mechanism 5 to move, realizing the adjustment of the cutting position of the cutting knife 7, improving the accuracy of paper cutting, after the equipment is started, the push cylinder 55 also starts to work, when the output end of the push cylinder 55 extends, that is, when it moves downward, it pushes the sliding part 57 to move downward in the inner cavity of the sliding groove 56, and the sliding part 57 drives the cutting knife 7 to move downward, thereby cutting the paper on the tray 10, the actual cutting mode is determined according to the actual situation, and can refer to the existing cutting equipment on the market, and then reasonably combined and arranged, which is the prior art and will not be described in detail in this paper, after the paper is cut, the user controls the lifting motor 11 to lower the lifting mechanism 9 and the tray 10, so that the cut paper placed on the tray 10 can also be lowered to the conveying mechanism 1, during the lowering process, when the bottom of the tray 10 contacts the conveying roller 104 on the conveying mechanism 1, the lifting mechanism 9 will continue to lower, but will not contact the conveying roller 104, so that the frame composed of the horizontal supporting plate 91 and the vertical supporting rod 92 will be separated from the tray 10, and then conveyed backward by the conveying roller 104, at this time, the position of the tray 10 will appear in the position of the tray 2 18, as shown, and then continue to convey backward for workers to pack, it should be noted that the number of trays is two, that is, the tray 10 and the tray 2 18, so that in the continuous circulation of the two trays, continuous feeding, cutting and discharging can be realized, time is saved, and production efficiency is improved.

[0060] Check whether the hardware of each part of the machine is normal and whether there is a loose or malfunctioning part, and start the machine after confirming that it is correct;

[0061] The workbench should be cleaned before the machine works, and other sundries are not allowed to be placed to prevent the machine from being damaged; ​

[0062] Step two, turn on the power, wait for the device initialization, while observing the device running normally;

[0063] Step three, after the machine running normally, the user will put the tray one 10 with paper to the left side of the transmission mechanism 1, and then by the transmission mechanism 1 to the right side, that is, to the rear of the machine;

[0064] Step four, when the tray one 10 is transmitted to the position of the lifting mechanism 9, the tray one 10 will move to the inside of the lifting mechanism 9 under the push of the transmission mechanism 1, so that the frame of the lifting mechanism 9 will not touch the tray one 10, so it can smoothly enter the inside of the lifting mechanism 9 under the transmission of the transmission mechanism 1, when the machine detects that the tray one 10 completely enters the inside of the lifting mechanism 9, it can control the lifting motor 11 to work to lift the lifting mechanism 9, so as to lift the tray one 10;
