Description

Technical Field

[0001] This application relates to the field of paper box production equipment technology, specifically a paper box forming machine. Background Technology

[0002] In the packaging machinery industry, paper box forming machines are indispensable equipment for making paper boxes. The entire machine operates in a fully automated manner, and its production efficiency is more than 30 times higher than that of traditional processes. It is applicable to the production of shoe boxes, shirt boxes, jewelry boxes, and gifts.

[0003] An existing patent (publication number: CN218615617U) discloses a paper box forming machine, including an operating frame and an unloading frame. The machine is characterized by several support columns fixedly mounted on the bottom side of the operating frame, an inverted U-shaped frame fixedly mounted on the upper side of the operating frame with a through hole on the upper side, a pushing cylinder fixedly mounted inside the through hole, a forming pressure block fixedly connected to the drive shaft end of the pushing cylinder, a fixing block fixedly mounted on the upper side of the operating frame, a hydraulic cylinder fixedly mounted on one side of the fixing block, a pushing plate fixedly mounted on one side of the shaft end of the hydraulic cylinder, and several positioning plates fixedly mounted on the upper side of the operating frame, each with a positioning device. This invention, by setting up positioning plates, fixing sleeves, sliding plates, baffles, L-shaped limiting frames, locking bolts, fixing blocks, hydraulic cylinders, and pushing plates, allows for free adjustment of the distance between the L-shaped limiting frames, reducing material forming position errors, lowering the finished product defect rate, and significantly saving material costs.

[0004] Although the distance between the L-shaped limit frames can be freely adjusted to reduce material forming position errors, the aforementioned comparative documents lack automated quality inspection and still rely on manual sampling inspection, resulting in a high rate of missed inspections. Furthermore, sorting is manual, requiring operators to manually remove defective products, which affects production efficiency. To address these issues, a paper box forming machine is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a paper box forming machine with automated quality inspection and removal of defective products, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a paper box forming machine, comprising a forming component, a conveying component, and a detection component. The conveying component includes a frame and a conveyor belt installed inside the frame. A protective plate is fixedly connected to the upper surface of the frame. The detection component includes a top plate fixedly connected to the top of the protective plate. A vision inspection module is installed on the bottom surface of the top plate. An image analysis module and a high-performance microcontroller are fixedly connected to the upper surface of the top plate. Both the vision inspection module and the image analysis module are electrically connected to the high-performance microcontroller. An extension plate is fixedly connected to one side of the protective plate. A sorting cylinder electrically connected to the high-performance microcontroller is fixedly connected to the outer surface of the extension plate. A sorting plate is fixedly connected to the output end of the sorting cylinder. A collection box is fixedly connected to the outer surface of the conveyor belt. The collection box corresponds to the position of the sorting plate.

[0007] The above solution enables rapid prototyping of multi-sized cardboard boxes through multiple components in the forming assembly. The conveying assembly achieves stable transport via a conveyor belt and protective plate. The detection assembly uses a vision detection module to collect images, and an image analysis module compares defects. A high-performance microcontroller controls a sorting cylinder to drive a sorting plate to push defective products into a collection box. This solves the problems of high missed detection rate and low sorting efficiency in manual sampling. The controller integrates and regulates various electrical components, significantly reducing manual intervention and making it more practical.

[0008] Furthermore, the molding component includes a rectangular frame and a molding area inside the rectangular frame. A first adjusting cylinder is installed on both sides of the outer surface of the rectangular frame, and an L-shaped feeding plate is fixedly connected to the output end of each of the two first adjusting cylinders.

[0009] With the above scheme, when the first adjusting cylinder is activated, the L-shaped feeding plate can be moved inside the rectangular frame, thereby adjusting the spacing between the two L-shaped feeding plates to meet the feeding needs of paperboards of different sizes.

[0010] Furthermore, a feeding cylinder is fixedly connected to one side of the outer surface of the rectangular frame, and a feeding plate is fixedly connected to the output end of the feeding cylinder.

[0011] With the above solution, when the feeding cylinder is started, it can drive the feeding plate to move. The movement of the feeding plate can push the cardboard placed on the two L-shaped feeding plates into the upper part of the forming area, which facilitates the subsequent cardboard box forming work.

[0012] Furthermore, a second adjusting cylinder is installed around the perimeter of the forming area, and an arc-shaped forming plate is fixedly connected to the output end of each second adjusting cylinder.

[0013] With the above scheme, when the second adjusting cylinder is activated, it can drive the arc forming plate to move. By adjusting the position of the four arc forming plates, paper boxes of different sizes can be easily formed.

[0014] Furthermore, a bracket is fixedly connected to the upper surface of the rectangular frame, and a pressing cylinder is installed on the top of the bracket. The output end of the pressing cylinder is connected to a forming block by bolts, and the forming block is located above the four arc-shaped forming plates.

[0015] The above method allows the forming block to move downwards when the pressure cylinder is activated, thereby enabling the paperboard below it to be pressed and formed.

[0016] Furthermore, the outer surface of the rectangular frame is fixedly connected to two first support columns and two connecting frames, both of which are fixedly connected to the outer surface of the protective plate.

[0017] The above solution allows for a stable connection between the rectangular frame and the protective plate via a connecting frame, enabling the cardboard box formed by the forming component to fall into the conveying component for transport and inspection.

[0018] Furthermore, four second support columns are fixedly connected to the bottom surface of the frame, and the bottom surfaces of the second support columns and the first support columns are located on the same horizontal plane.

[0019] The above scheme limits the relationship between the second support column and the first support column, enabling the molding component and the conveying component to be placed more stably on the ground, which is convenient for use.

[0020] Furthermore, a controller is fixedly connected to the outer surface of the protective plate, and the electrical components inside the molding assembly, conveying assembly, and detection assembly are all electrically connected to the controller.

[0021] The above solution allows for convenient debugging and control of the electrical components inside the molding, conveying, and testing components via a designated controller, simplifying the operation process.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This type of cardboard box forming machine uses a first adjusting cylinder in the forming assembly to drive the L-shaped feeding plate spacing adjustment and a feeding cylinder to push the cardboard to the forming area. A second adjusting cylinder controls the positioning of the arc-shaped forming plate, and a pressing cylinder drives the forming block to complete precise pressing, enabling rapid forming of cardboard boxes of various sizes. The conveying assembly achieves stable conveying through a conveyor belt and protective plate. The detection assembly uses a vision detection module to collect images, and an image analysis module to compare defects. A high-performance microcontroller controls a sorting cylinder to drive a sorting plate to push defective products into a collection box. This solves the problems of high missed detection rate and low sorting efficiency in manual sampling. The controller integrates and regulates various electrical components, significantly reducing manual intervention and making it more practical. Attached Figure Description

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0032] Please see Figure 1 , Figure 2 and Figure 3This embodiment of a paper box forming machine includes a forming component 1, a conveying component 2, and a detection component 3. The forming component 1 includes a rectangular frame 101 and a forming area 102 formed inside the rectangular frame 101. First adjusting cylinders 103 are installed on both sides of the outer surface of the rectangular frame 101. L-shaped feeding plates 104 are fixedly connected to the output ends of both first adjusting cylinders 103. When the first adjusting cylinders 103 are activated, the L-shaped feeding plates 104 can move inside the rectangular frame 101, thereby adjusting the spacing between the two L-shaped feeding plates 104 to accommodate feeding paperboard of different sizes. A feeding cylinder 105 is fixedly connected to one side of the outer surface of the rectangular frame 101. A feeding plate 106 is fixedly connected to the output end of the feeding cylinder 105. When the feeding cylinder 105 is activated, it can move the feeding plate 106, allowing the feeding plate 106 to be moved. The cardboard on the two L-shaped feeding plates 104 is pushed into the top of the forming area 102 to facilitate the subsequent cardboard box forming work. Second adjustment cylinders 107 are installed around the forming area 102. The output end of each second adjustment cylinder 107 is fixedly connected to an arc forming plate 108. When the second adjustment cylinder 107 is activated, it can drive the arc forming plate 108 to move. By adjusting the position of the four arc forming plates 108, cardboard boxes of different sizes can be easily formed. A bracket 109 is fixedly connected to the upper surface of the rectangular frame 101. A pressing cylinder 110 is installed on the top of the bracket 109. The output end of the pressing cylinder 110 is connected to a forming block 111 by bolts. The forming block 111 is located above the four arc forming plates 108. When the pressing cylinder 110 is activated, the forming block 111 can be moved down, thereby pressing down the cardboard below it to form the cardboard.

[0033] Please see Figure 2 , Figure 3 and Figure 4The conveying assembly 2 includes a frame 201 and a conveyor belt 202 installed inside the frame 201. A protective plate 204 is fixedly connected to the upper surface of the frame 201. Two first support columns 112 and two connecting frames 113 are fixedly connected to the outer surface of the rectangular frame 101. Both connecting frames 113 are fixedly connected to the outer surface of the protective plate 204. The connecting frames 113 can stably connect the rectangular frame 101 and the protective plate 204, so that the cardboard boxes formed by the forming assembly 1 can fall into the conveying assembly 2 for conveying and inspection. Four second support columns 202 are fixedly connected to the bottom surface of the frame 201. 03. The bottom surfaces of the second support column 203 and the first support column 112 are located on the same horizontal plane, which limits the relationship between the second support column 203 and the first support column 112. This allows the forming component 1 and the conveying component 2 to place the material more stably on the ground, making it convenient to use. After the cardboard is formed by the forming component 1, it will fall onto the second support column 203 for conveying and subsequent inspection. After the cardboard is formed, the four arc-shaped forming plates 108 can be moved away from each other by activating the four second adjusting cylinders 107, so that the formed cardboard box can fall onto the second support column 203.

[0034] Please see Figure 3 , Figure 4 and Figure 5The detection component 3 includes a top plate 301 fixedly connected to the top of the protective plate 204. A vision detection module 302 is installed on the bottom surface of the top plate 301. The vision detection module 302 can capture three-dimensional images of the formed cardboard boxes passing below. An image analysis module 303 and a high-performance microcontroller 304 are fixedly connected to the upper surface of the top plate 301. Both the vision detection module 302 and the image analysis module 303 are electrically connected to the high-performance microcontroller 304. The image analysis module 303 can determine the quality status in real time based on a preset algorithm and then feed the data back to the high-performance microcontroller 304 for processing. An extension plate 305 is fixedly connected to one side of the protective plate 204. A sorting cylinder 306 electrically connected to the high-performance microcontroller 304 is fixedly connected to the outer surface of the extension plate 305. The output end of cylinder 306 is fixedly connected to sorting plate 307, and the outer surface of conveyor belt 202 is fixedly connected to collection box 308. The position of collection box 308 corresponds to that of sorting plate 307. High-performance microcontroller 304 can control the start of sorting cylinder 306. When sorting cylinder 306 is started, it can move sorting plate 307, thereby pushing unqualified products conveyed on conveyor belt 202 into collection box 308, realizing the effect of automatic sorting. The outer surface of protective plate 204 is fixedly connected to controller 4. The electrical components inside forming component 1, conveying component 2 and detection component 3 are all electrically connected to controller 4. Through the controller 4, the electrical components inside forming component 1, conveying component 2 and detection component 3 can be conveniently debugged and controlled, simplifying the operation process.

[0035] In this embodiment, a cardboard box forming machine uses a first adjusting cylinder 103 in the forming component 1 to drive the L-shaped feeding plate 104 to adjust the spacing, and a feeding cylinder 105 to push the cardboard to the forming area 102. A second adjusting cylinder 107 controls the positioning of the arc-shaped forming plate 108, and a pressing cylinder 110 drives the forming block 111 to complete precise pressing, achieving rapid forming of multi-size cardboard boxes. The conveying component 2 uses a conveyor belt 202 and a protective plate 204 for stable conveying. The detection component 3 uses a vision detection module 302 to collect images, and an image analysis module 303 to compare defects. A high-performance microcontroller 304 controls a sorting cylinder 306 to drive a sorting plate 307 to push defective products into a collection box 308. This solves the problems of high missed detection rates and low sorting efficiency in manual sampling. The controller 4 integrates and controls various electrical components, significantly reducing manual intervention and making it more practical.

[0036] The working principle of the above embodiment is as follows: The cardboard is first placed on the L-shaped feeding plate 104 of the forming component 1. The first adjusting cylinder 103 drives the L-shaped feeding plates 104 on both sides to move laterally to adapt to cardboard of different sizes. Then, the feeding cylinder 105 pushes the feeding plate 106 to accurately feed the cardboard into the forming area 102. During the forming stage, the four second adjusting cylinders 107 adjust the arc forming plate 108 to surround and form the target box shape outline. The pressing cylinder 110 drives the forming block 111 to press down vertically to fix the creases of the cardboard. Then, the four second adjusting cylinders 107 adjust the arc forming plate 108 to move away from each other, so that the formed cardboard box falls onto the conveyor belt 202 of the conveying component 2. During the conveying process, the protective plate 204 ensures that the cardboard box moves stably to the inspection station. The vision inspection module 302 detects the cardboard box through a high frame rate. An industrial camera captures 3D images of the cardboard box. The image analysis module 303, based on a preset algorithm, including edge detection, corner angle calculation, and surface defect recognition, determines the quality status in real time and transmits the results to a high-performance microcontroller 304. If cracks, deformations, or dimensional deviations are detected, the high-performance microcontroller 304 immediately triggers a sorting cylinder 306, driving a sorting plate 307 to push defective products laterally into a collection box 308. Qualified products continue to be transported to a designated area via a conveyor belt 202. The controller 4 integrates and controls the electrical components inside the forming component 1, conveying component 2, and detection component 3 to achieve a relatively automated production process. At the same time, it records production data for quality traceability. This solution effectively reduces manual intervention and improves the yield rate through the deep integration of mechanical structure adjustment and intelligent detection and sorting.
