Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper processing equipment, in particular to a vertical servo corrugated paper slotting machine. Background Art

[0002] With the continuous development and progress of science and technology, the printing effect of digital printing has been greatly improved in recent years, and the proportion of digital printing in various printing industries has also increased. In the corrugated paper industry, the proportion of digital printing has also increased. Compared with traditional plate printing, the cost of onepass high-speed digital printing machine has a direct relationship with the printing width. The larger the width, the more nozzles there are. The cost of nozzles accounts for a large proportion of the whole machine, so when digital printing machines print, cardboard is generally printed vertically, so as to achieve a narrower printing width and print larger cardboard.

[0003] The existing slotting machines and die-cutting machines on the market all feed paper horizontally. If the digital printing machine wants to connect with the existing slotting machines on the market after vertical printing, it needs to make a cardboard turning machine and then reposition the slotting, which not only increases the cost of the machine, but also takes up plant space and increases energy consumption. There are two main types of corrugated paper circular knife slotting machines used in the market, one is the traditional circular knife machine, and the other is the servo slotting machine.

[0004] The traditional circular knife machine is mainly composed of a paper feeding structure, a wire pressing structure, and a slotting structure. The slotting structure is composed of an upper knife shaft and a lower knife shaft. The upper and lower knife shafts have 4 knife discs mounted on a shaft and rotate synchronously. The upper knife disc is equipped with 2 arc upper blades and the position can be relatively adjusted to adjust the distance between the front and rear two slots, that is, the box height. The slotting machine uses gear transmission to synchronize the linear speed of the feeding, upper and lower wire pressing shafts, upper and lower knife disc shafts, etc. to achieve slotting. The advantage of this slotting machine is high efficiency. The maximum linear speed can reach about 2.5m / s, which is particularly fast, especially for a machine specially designed for a carton with a reasonable diameter to open a carton. However, one rotation of the knife shaft is to open a cardboard. When the machine opens a small cardboard, it runs empty most of the time. The gap between the front and rear two cardboards is large. At the same time, the size of the knife disc limits the distance between the two slots, that is, the box height. Therefore, when it is necessary to open a cardboard with a large difference in box height, multiple machines of different models are required, which is not very versatile and increases the company's costs.

[0005] Compared with traditional slotting machines, the servo circular knife machine has a servo-controlled power motor for the cutter shaft. The slotting knife can hover and has better adaptability to different cardboard sizes. The box height can be from 400MM to theoretically unlimited length. However, the box length and width are limited. Generally, the sum of the entire corrugated paper and the width plus the length of the box is no more than 3 meters.

[0006] Whether it is a traditional circular knife slotting machine or a servo slotting machine, the paper feeding direction is horizontal, and the total length of the corrugated cardboard that can be cut does not exceed 3 meters. Especially with the increasing popularity of digital printing machines (generally vertical paper feeding), the machine connected to the slotting machine needs to turn first and then reposition it into the slotting machine, which increases the cost of the machine and occupies a larger space. To this end, a vertical servo corrugated paper slotting machine is proposed to solve the above problems. Utility Model Content

[0007] In view of this, the present disclosure provides a vertical servo corrugated paper slotting machine, aiming to solve the problems in the background technology that the existing slotting machines are difficult to connect with digital printing machines, the processed cardboard length is limited, and the versatility is low.

[0009] Further description of the above-mentioned scheme, the pre-pressing mechanism includes a main motor, a pre-pressing upper roller, and a pre-pressing lower roller. The main motor drives the pre-pressing lower roller through a reducer and a coupling. The other end of the pre-pressing lower roller is provided with a power wheel. The power wheel drives the corner knife mechanism, the pre-pressing upper roller, the pressurizing mechanism, the clamping roller mechanism, and the upper knife roller to rotate through gears, thereby realizing the synchronous operation of multiple components and saving the number of motors.

[0010] Further description of the above scheme, the corner knife mechanism includes a corner knife motor, an upper corner knife roller, and a lower corner knife roller. The corner knife motor drives the upper corner knife roller to cut the paper head and paper tail of the cardboard, and the lower corner knife roller is driven to rotate by a power wheel and a gear. The pre-pressing upper roller is also connected to the pre-pressing line lifting motor. The pre-pressing line lifting motor simultaneously drives the lifting eccentric gear and lifting transmission shaft of the pre-pressing upper roller to ensure that both ends of the pre-pressing upper roller are lifted and lowered at the same time, so as to achieve control of the cardboard and adjust the spacing between the pre-pressing upper roller and the pre-pressing lower roller according to the thickness of the cardboard. The pressing line mechanism includes a pressing line lifting motor, a pressing line roller, a pressing line roller, and a lifting transmission shaft. The power wheel drives the pressing line roller and the pressing line roller to rotate through gears. The pressing line lifting motor drives the lifting eccentric gear and the lifting transmission shaft to drive both ends of the pressing line roller to lift and lower at the same time, so as to press the corresponding position of the cardboard. The clamping roller mechanism includes an upper clamping roller, a lower clamping roller, and a clamping roller lifting motor. The power wheel drives the upper and lower clamping rollers to rotate through gears to push the paperboard into the slotting mechanism. The clamping roller lifting motor drives the lifting eccentric gear and the lifting transmission shaft to drive the two ends of the upper clamping roller to lift and lower at the same time, providing the paperboard with forward power, ensuring that the slotting mechanism accurately and effectively slots the paperboard. The knife roller lifting motor of the slotting mechanism drives the lifting gear, the lifting eccentric gear, and the slotting lifting transmission shaft to drive the upper knife roller to lift and lower, so as to slot the paperboard at a specific position.

[0011] As an improvement, the slotting machine includes two upper guide fixing plates, which are slidably mounted on the guide rails on the top of the bracket, and the upper opening and closing screws are driven by the screw servo motor to drive the upper guide fixing plates to adjust and position the cardboard to be slotted.

[0012] As an improvement, the screw servo motor drives the lower opening and closing screw to rotate through a chain, and the lower opening and closing screw drives the lower guide fixing plate to adjust the position of the cutter mounting seat.

[0016] Furthermore, a number of sensors for detecting the state and position of the cardboard are installed on the bracket, and the sensors and motors are connected to the control system of the slotting machine.

[0017] The processing steps of the slotting machine are as follows: after the cardboard enters the machine, the sensor detects the paper head, and then the PLC calculates the position and uses the corner knife mechanism to cut the corners of the paper head and tail at a specific position of the cardboard. The cardboard passes through the pre-pressing mechanism and the pressing mechanism to press the cardboard and push the cardboard forward. The clamping roller mechanism sends the cardboard into the slotting mechanism, and the PLC calculates the position of the cardboard and drives the slotting knife servo motor to slot the cardboard.

[0038] like Figure 2 , 6 As shown, the screw servo motor 60 drives the lower opening and closing screw 64 to rotate through the chain 65, and the lower opening and closing screw 64 drives the lower guide fixing plate 62 to adjust the position of the cutter mounting seat 521. A single screw servo motor 60 can be used to synchronously drive the upper guide fixing plate 61 and the lower guide fixing plate 62.

[0039] In this embodiment, four slotting knives 522 are evenly mounted on two cutter mounting seats 521, and the cutter mounting seats 521 are provided with key slots 523. The cutter mounting seats 521 are key-connected with the lower cutter roller 52 to realize rotation.

The lower guide fixing plate 62 is slidably mounted on the middle guide rail 71 of the bracket 7, and is sleeved on the corner cutter lower roller 12, the pre-pressing lower roller 22, and the line pressing lower roller 32 through a sleeve. The bracket 7 of this embodiment is equipped with an inspection door 72 and a cover plate 73 to wrap the corner cutter mechanism 1, the pre-pressing mechanism 2, the line pressing mechanism 3, the clamping roller mechanism 4, and the slotting mechanism 5. The bracket 7 is also equipped with a number of sensors for detecting the state and position of the cardboard, and the sensors and the motor are connected to the control system of the slotting machine.

[0040] In order to have a more thorough and comprehensive understanding of the disclosed content of the utility model, the principle thereof is further explained below in combination with the usage method.

[0041] like Fig.11 As shown, the cardboard is placed vertically into the slotting machine, the main motor 40 is started and connected to the pre-pressing lower roller 22 through a coupling after being decelerated by the reducer. The other end of the pre-pressing lower roller 22 is provided with a power wheel 44, as shown in FIG. Figure 7 As shown, the power wheel 44 drives the lower roller 12 of the corner knife, the upper pre-pressing roller 21, the lower roller 32 of the creasing line, the lower roller 31 of the creasing line, the upper clamping roller 41, the lower clamping roller 42, and the upper knife roller 51 to rotate through the gears, and the paperboard is driven by the above mechanisms. When the paperboard enters the corner knife mechanism 1, the sensor detects the paper head, and the PLC calculates the position to cut the paper head and paper tail at a specific position of the paperboard.

[0042] When the cardboard passes through the pre-pressing mechanism 2 and the pressing mechanism 3, the pre-pressing mechanism 2 and the pressing mechanism 3 press the cardboard and push the cardboard forward. In order to ensure the accuracy of the position of the cardboard during the slotting process, the cardboard will pass through the clamping roller mechanism 4, and the clamping roller mechanism 4 will then send the cardboard into the slotting mechanism 5.

[0043] The upper pre-pressing roller 21, the press line roller 31, the upper clamping roller 41, and the upper knife roller 51 can all be lifted and lowered by the lifting motor driving the lifting intermediate gear 513, the lifting eccentric gear 514, and the slotted lifting transmission shaft 515. Fig.10 As shown, to adapt to different cardboard thickness.

[0044] When the cardboard enters the slotting mechanism 5, the PLC will calculate the position of the cardboard, such as Fig.11 As shown, at a specific paperboard position, the slotting knife servo motor 53 is started to drive the lower knife roller 52 to rotate and slot the paperboard. Repeating the above actions can achieve continuous high-speed slotting.

[0045] It should be noted that when the lead screw servo motor 60 is started, it not only drives the upper opening and closing lead screw 63 to rotate, but also drives the lower opening and closing lead screw 64 to rotate through the chain 65. In this scheme, the upper opening and closing lead screw 63 and the lower opening and closing lead screw 64 are divided into two sections from the middle, and the left and right screws are respectively installed, and the middle is fixed with a connecting sleeve, so that when the lead screw rotates, the left lead screw nut moves left, and the right lead screw nut moves right, and the two upper guide fixing plates 61 or the lower guide fixing plates 62 move left and right synchronously with the middle of the slotting machine. In other schemes, the upper opening and closing lead screw 63 and the lower opening and closing lead screw 64 are both installed with two lead screw nuts, and the two lead screw nuts are reversely installed on the two upper guide fixing plates 61 and the lower guide fixing plates 62. When the lead screw rotates, the two upper guide fixing plates 61 or the lower guide fixing plates 62 move left and right synchronously with the middle of the slotting machine, and the slotting knife 522 slots the cardboard at the specified position.

[0046] Those skilled in the art will readily appreciate other embodiments of the present disclosure after considering the specification and practicing the present disclosure.
