Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard box processing technology, specifically to an intelligent die-cutting device for corrugated cardboard boxes. Background Technology

[0002] Corrugated cardboard boxes are a relatively ideal packaging container. They are lightweight, sturdy, shock-absorbing, and suitable for mechanized production. For many years, they have been used for transport and sales packaging. Corrugated cardboard boxes have the advantages of being recyclable, environmentally friendly, easy to load and unload, and saving wood. The structure of corrugated cardboard consists of four parts: the linerboard, the core linerboard, the inner linerboard, and the corrugated paper that has been processed into a wavy shape. These four parts are bonded together.

[0003] The existing intelligent die-cutting device for corrugated boxes (application number 202410045744.9, a die-cutting device and method for corrugated box production) uses a conveying suction cup on the intelligent die-cutting device to convey the die-cut corrugated boxes. However, during the die-cutting process, the device cannot quickly separate the die-cut corrugated boxes, which affects the die-cutting quality and efficiency of the intelligent die-cutting device. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide an intelligent die-cutting device for corrugated boxes to solve the technical problem that existing intelligent die-cutting devices for corrugated boxes cannot quickly separate the die-cut corrugated boxes in a timely manner, thus affecting the die-cutting quality and efficiency of the intelligent die-cutting device for corrugated boxes.

[0005] According to the technical solution provided in the embodiments of this application, a smart die-cutting device for corrugated cardboard boxes includes a die-cutting table, and a die-cutting component is provided in the middle of the die-cutting table for die-cutting processing of corrugated cardboard boxes.

[0006] The die-cutting assembly includes an upper die-cutting plate, a lower die-cutting plate, two moving mechanisms, and several returning mechanisms. The upper die-cutting plate and the lower die-cutting plate are arranged side by side and spaced apart. The two moving mechanisms are respectively installed on the upper die-cutting plate and the lower die-cutting plate for conveying the corrugated boxes separated after die-cutting. The several returning mechanisms are evenly installed at the bottom of the lower die-cutting plate for the separation and return of the lower die-cutting plate.

[0007] Two positioning mechanisms are arranged side by side and spaced apart on both sides of the separation groove on the die-cutting table for separating and positioning the lower die-cutting plate.

[0008] Furthermore, the upper die-cutting plate and the lower die-cutting plate have similar structures, both being rectangular, and the die-cutting surfaces of the upper die-cutting plate and the lower die-cutting plate are provided with a number of roller grooves for mounting a number of rollers on each of the moving mechanisms.

[0009] Furthermore, the moving mechanism includes a rotary drive, a worm gear, three worm wheels, three transmission shafts, and several rollers. The rollers are mounted on the three transmission shafts, and the three worm wheels are respectively mounted on the corresponding ends of the transmission shafts. Each worm wheel is meshed with corresponding teeth on the worm gear, and the worm gear is fixedly connected to the output end of the rotary drive, so that the rotary drive drives the rollers on the three transmission shafts to roll synchronously.

[0010] Furthermore, the recovery mechanism includes a movable rod, a fixed rod, a first recovery component, and a second recovery component. The movable rod is movably mounted on the fixed rod, the first recovery component is mounted in a groove on the fixed rod and abuts against the bottom of the movable rod, and the second recovery component is sleeved on the outside of the movable rod and the fixed rod for elastic support of the lower die-cutting plate.

[0011] Furthermore, a positioning groove is provided on the side of the lower die-cutting plate, and the positioning rod on the positioning mechanism is engaged in the positioning groove under the drive of the telescopic drive component. A start button is installed in the positioning groove, and the start button is electrically connected to the moving mechanism for starting control of the moving mechanism.

[0012] Furthermore, a separation port is provided at the rear end of the separation tank, which is connected to a collection box for collecting the separated corrugated cardboard boxes.

[0013] Furthermore, corresponding conveying mechanisms are provided on both sides of the die-cutting table so that the conveyor belt on the conveying mechanism can transport and feed the die-cut corrugated cardboard boxes.

[0014] Furthermore, a control panel is installed at the front end of the die-cutting table. The control panel is electrically connected to the die-cutting assembly for intelligent die-cutting control of corrugated boxes.

[0015] Furthermore, the top of the upper die-cutting plate is connected to the output end of the cylinder, so that the cylinder, under the input of a positive pressure air source, pushes the upper die-cutting plate to move downward in the vertical direction, thereby die-cutting and separating the corrugated cardboard box placed on the lower die-cutting plate.

[0016] In summary, the beneficial effects of this application are as follows:

[0017] 1. By setting a separation groove on the die-cutting table, the upper die-cutting plate moves downward under the push of the cylinder, thereby die-cutting the corrugated cardboard box placed on the lower die-cutting plate. The die-cut corrugated cardboard continues to move downward along the separation groove under the downward push of the upper die-cutting plate, thereby separating the corrugated cardboard box, thus improving the die-cutting and separation efficiency of the intelligent die-cutting device for corrugated cardboard boxes.

[0018] 2. By setting corresponding moving mechanisms on the die-cutting surfaces of the upper and lower die-cutting plates, the moving mechanisms drive the worm gear to rotate after the rotating drive component drives the worm to rotate, thereby driving the corresponding transmission shafts to rotate, so that the rollers installed in parallel and at intervals on each transmission shaft rotate, and then each rotating roller transports the separated corrugated cardboard box to the separation port and collects it in the collection box connected to the separation port, thereby improving the intelligent die-cutting quality of the corrugated cardboard box;

[0019] Third, by setting two corresponding positioning mechanisms on the separation groove, when the lower die-cutting plate moves along the separation groove to the limit position, the telescopic drive component on the positioning mechanism drives the positioning rod to extend, and then the positioning rod is locked in the positioning groove on the lower die-cutting plate. This allows the positioning rod to activate the start button of the moving mechanism in the positioning groove, so that the positioning mechanism positions the lower die-cutting plate while controlling the start of the moving mechanism, thereby improving the intelligence and linkage of the die-cutting device.

[0020] Fourth, by setting several return mechanisms at the bottom of the lower die-cutting plate, the first and second return components compressed by the moving rod and the lower die-cutting plate on the return mechanism are spring-loaded back, thereby driving the lower die-cutting plate back to its initial position without affecting the intelligent die-cutting efficiency of the corrugated cardboard.

It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] A smart die-cutting device for corrugated cardboard boxes, the structure of which is as follows: Figures 1-5 As shown, the device includes a die-cutting table 100, with a die-cutting assembly 200 positioned in the middle to perform intelligent die-cutting on corrugated cardboard. The die-cutting assembly 200 includes an upper die-cutting plate 210, a lower die-cutting plate 220, two moving mechanisms 230, and several return mechanisms 240. The upper die-cutting plate 210 and the lower die-cutting plate 220 are arranged side-by-side and spaced apart, allowing the upper die-cutting plate 210 to move downwards under the push of a cylinder, thereby die-cutting the corrugated cardboard during the downward movement. The two moving mechanisms 230 are respectively installed correspondingly on the upper die-cutting plate 210 and the lower die-cutting plate 220. The die-cut surface on plate 20 is used for conveying the corrugated cardboard boxes after die-cutting. Several return mechanisms 240 are evenly installed at the bottom of the lower die-cutting plate 220 so that the return mechanisms 240 are used for the return of the lower die-cutting plate 220 after separation, without affecting the normal use of the intelligent die-cutting device. Two positioning mechanisms 300 are arranged side by side and spaced apart on both sides of the separation groove 110 on the die-cutting table 100. They are used for positioning the lower die-cutting plate 220 as it moves along the separation groove 110, so that after the lower die-cutting plate 220 moves to the limit position, it is positioned by the positioning mechanism 300, which facilitates the moving mechanism 230 to move the separated corrugated cardboard boxes out of the lower die-cutting plate 220.

[0031] As a preferred embodiment, please refer to Figure 2 and Figure 4The upper die-cutting plate 210 and the lower die-cutting plate 220 have similar structures, both being rectangular. Several roller 235 grooves are provided on the die-cutting surfaces of the upper die-cutting plate 210 and the lower die-cutting plate 220. Several rollers 235 on each moving mechanism 230 are installed in the corresponding roller 235 grooves, so that the rollers 235 rotate synchronously and in the same direction under the drive of the rotation drive member 231, thereby separating and conveying the separated corrugated cardboard.

[0032] As a preferred embodiment, please refer to Figure 4 The moving mechanism 230 includes a rotation drive 231, a worm 232, three worm wheels 233, three transmission shafts 234, and several rollers 235. The rollers 235 are mounted on the three transmission shafts 234, and the three worm wheels 233 are respectively mounted on the corresponding ends of the transmission shafts 234. Each worm wheel 233 is meshed with the corresponding teeth on the worm 232. The worm 232 is fixedly connected to the output end of the rotation drive 231, so that the moving mechanism 230 is driven by the rotation drive 231 to rotate the worm 232, thereby causing each worm wheel 233 meshing with the worm 232 to rotate synchronously, thereby causing each transmission shaft 234 with the corresponding worm wheel 233 to rotate, so that each roller 235 mounted in parallel and spaced apart on each transmission shaft 234 rotates synchronously and in the same direction, thereby causing each rotating roller 235 to transport the separated corrugated cardboard box to the separation port 120 on the cutting table.

[0033] As a preferred embodiment, please refer to Figure 3 and Figure 5The return mechanism 240 includes a movable rod 241, a fixed rod 242, a first return component 243, and a second return component 244. The movable rod 241 is movably mounted on the fixed rod 242, while the first return component 243 is installed in a groove on the fixed rod 242 and abuts against the bottom of the movable rod 241. The second return component 244 is sleeved on the outside of the movable rod 241 and the fixed rod 242, providing elastic support for the lower die-cutting plate 220. Simultaneously, an air inlet is provided at the bottom of the fixed rod 242, which is connected to an air pump. During the corrugated cardboard die-cutting process, the air pump inputs positive pressure air into the fixed rod 242, causing the movable rod 241 on the fixed rod 242 to be in a limited position, and the return mechanism 240 to be locked. Since the upper die-cutting plate 210 cannot move vertically downwards, after die-cutting, the die-cut corrugated cardboard needs to be separated so that the cylinder pushes the lower die-cutting plate 220, which is in contact with the upper die-cutting plate 210, to move downwards along the separation groove 110. This causes several moving rods 241 installed at the bottom of the lower die-cutting plate 220 to move downwards along the fixed rod 242, thereby compressing the first elastic metal spring that is in contact with the upper die-cutting plate 220. At the same time, the second return metal spring 244, which is sleeved on the outside of the fixed rod 242, is also compressed. After separation, the elastic potential energy generated by the recovery of the first return metal spring 243 and the second return metal spring 244 pushes the lower die-cutting plate 220 upwards, returning it to its initial position. This does not affect the die-cutting efficiency and processing quality of the intelligent die-cutting device for corrugated cardboard boxes.

[0034] As a preferred embodiment, please refer to Figure 4 and Figure 5 The lower die-cutting plate 220 has a positioning groove 221 on its side. When the lower die-cutting plate 220 moves down along the separation groove 110 to the limit position, the positioning rod 320 on the positioning mechanism 300 is engaged in the positioning groove 221 under the drive of the telescopic drive member 310, and presses the start button installed in the positioning groove 221, so that the moving mechanism 230 connected to the start button is started, and then the moving mechanism 230 transports the die-cut and separated corrugated carton bottom plate on the lower die-cutting plate 220.

[0035] As a preferred embodiment, please refer to Figure 2 and Figure 3 The rear end of the separation tank 110 is also provided with a separation port 120, which is connected to the collection box 130 so that the moving mechanism 230 can transport the separated corrugated cardboard from the separation port 120 to the collection box 130 for collection.

[0036] As a preferred embodiment, please refer to Figure 1 and Figure 2The die-cutting table 100 is equipped with corresponding conveying mechanisms 400 on both sides, so that the conveyor belt on the conveying mechanism 400 can transport and feed the die-cut corrugated boxes and convey the residual material after separation. The front end of the die-cutting table 100 is equipped with a control panel 140, which is electrically connected to the die-cutting assembly 200, so that the control panel 140 can control the intelligent die-cutting device to perform intelligent die-cutting on the corrugated boxes, thereby improving the processing efficiency and processing quality of the corrugated boxes.

[0037] As a preferred embodiment, please refer to Figure 1 and Figure 2 The top of the upper die-cutting plate 210 is connected to the output end of the cylinder, so that the cylinder, under the input of the positive pressure air source, pushes the upper die-cutting plate 210 to move downward in the vertical direction, thereby die-cutting and separating the corrugated cardboard box placed on the lower die-cutting plate 220.

[0038] The working principle of this intelligent die-cutting device for corrugated cardboard boxes is as follows:

[0039] During the die-cutting process of corrugated cardboard boxes by the intelligent die-cutting device, a rectangular separation groove 110 is set on the die-cutting table 100, allowing the operator to set the die-cutting parameters through the control panel 140. This causes the upper die-cutting plate 210 to move downward under the positive pressure of the cylinder, thereby die-cutting the corrugated cardboard box placed on the lower die-cutting plate 220. The die-cut cardboard needs to be separated, so the cylinder continues to push the upper die-cutting plate 210 downward vertically, causing the lower die-cutting plate 220, which abuts against the upper die-cutting plate 210, to move downward along the separation groove 110, thereby cutting the die-cut corrugated cardboard box. During the separation of cardboard boxes, as the lower die-cutting plate 220 moves down along the separation groove 110, two corresponding positioning mechanisms 300 are provided on the separation groove 110. When the lower die-cutting plate 220 moves to the limit position along the separation groove 110, the telescopic drive component 310 on the positioning mechanism 300 is activated, driving the positioning rod 320 to extend. This causes the positioning rod 320 to engage with the positioning groove 221 on the lower die-cutting plate 220, thereby activating the start button of the moving mechanism 230 installed in the positioning groove 221. This allows the positioning mechanism 300 to position the lower die-cutting plate 220 while simultaneously controlling... When the moving mechanism 230 is activated, the corresponding moving mechanisms 230 on the die-cutting surfaces of the upper die-cutting plate 210 and the lower die-cutting plate 220 are activated synchronously. This allows the moving mechanism 230 to drive the worm gear 232 to rotate after the rotation drive member 231 drives it to rotate, which in turn drives the corresponding transmission shafts 234 to rotate. This causes the rollers 235, which are installed parallel and spaced apart on each transmission shaft 234, to rotate. The rotating rollers 235 then transport the separated corrugated boxes to the separation port 120 on the cutting table, where they are collected in the collection box 130 connected to the separation port 120. After separation, the boxes are... The metal springs of the first return element 243 and the second return element 244 on the compressed return mechanism 240 return, thereby causing the die-cutting plate 220 to return to its initial position by the force generated by the return of the metal springs. This does not affect the intelligent die-cutting of the corrugated cardboard, thereby improving the intelligent die-cutting efficiency and die-cutting quality of the corrugated cardboard. Meanwhile, the conveying mechanism 400 set on both sides of the cutting table is activated to move and remove the excess material of the die-cut and separated corrugated cardboard. The next corrugated cardboard to be processed is moved to the die-cutting assembly 200, so that the corrugated cardboard can be continuously die-cut on the die-cutting table 100.

[0040] The above description is merely a preferred embodiment of this application and an explanation of the technical principles and solutions employed. Furthermore, the scope of the utility model involved in this application is not limited to the specific combination of the above-described technical features, but should also cover other technical solutions formed by any combination of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
