Detailed implementation manners

[0025] To facilitate the understanding of this application, the following will describe this application more comprehensively with reference to the relevant drawings. Embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of this application more thorough and comprehensive.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this application belongs. The terms used in the specification of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0027] Combined with Figures 1-5 As shown in, a corrugated cardboard film covering mechanism includes:

[0028] Workbench 1, which is a rectangular base and is mainly used to support and fix the entire film covering equipment. During actual use, moving structures such as rollers can be added to its bottom to facilitate its transportation;

[0029] Conveying rollers 2, multiple are provided and are located in the hollow part at the center of the top surface of the workbench 1. Rubber sleeves are provided on their surfaces, and the purpose is to increase the surface friction to facilitate the conveyance of cardboard;

[0030] The fixing frame 3 is arranged on both sides of the conveying roller 2, and a baffle plate 31 is arranged on the fixing frame 3. The distance between the top of the baffle plate 31 and the conveying roller 2 is just enough to pass a cardboard. Therefore, when the staff neatly stacks the cardboard on one side of the baffle plate 31, it can cooperate with the conveying roller 2 to convey it to the laminating process in sequence;

[0031] There are four lifting platforms 4, which are arranged in a rectangular structure on both sides of the conveying roller 2. A positioning frame 5 is provided on the top of the lifting platform 4, and a hydraulic cylinder is used as a driving element inside the lifting platform 4;

[0032] The guide assembly 7 is used to assist the transportation of the corrugated cardboard and also plays a certain fixing role to prevent the cardboard from shaking during the laminating process;

[0033] A dust removal component 6, for removing dust and debris from the surface of the corrugated cardboard;

[0034] The laminating roller 8 and the heating roller 9 are roller structures for heat-sealing and laminating the surface of the paperboard, and a laminating roll is fixedly mounted on the laminating roller 8.

[0035] For details, please refer to Figure 3 Several conveying rollers 2 are arranged side by side and at intervals, and transmission gears 21 are provided at both ends thereof. Every two adjacent conveying rollers 2 are linked to the transmission gears 21 at their ends through a chain 22, so that all the conveying rollers 2 move in the same direction. At the same time, a driving motor 23 is also provided on the workbench 1, and the output end of the driving motor 23 is connected to one of the conveying rollers 2 for transmission.

[0036] The positioning frame 5 is configured as a rectangular frame, and a slide groove 51 is provided on the inner wall of the frame. Three mounting plates 52 are also provided inside the positioning frame 5. The three mounting plates 52 are all arranged in the conveying direction of the corrugated cardboard, and their two ends extend outward and are slidably inserted into the slide groove 51. At the same time, the bottom surfaces of the three mounting plates 52 are correspondingly located in the middle and on both sides of the corrugated cardboard.

[0037] The guide assembly 7 includes a plurality of guide wheels 71 arranged at intervals on the bottom surface of the mounting plate 52. The bottom surfaces of the plurality of guide wheels 71 are on the same horizontal plane, so they are in contact with the surface of the corrugated cardboard on the conveying roller 2 at the same time. Combined with the position distribution of the above-mentioned mounting plate 52, the corrugated cardboard is pressed and fixed, effectively avoiding shaking of the corrugated cardboard when part of it enters the laminating part, greatly improving the stability of transportation, and helping to improve the production quality.

[0038] The dust removal component 6 includes a suction nozzle 61 arranged on the mounting plate 52. Multiple suction nozzles 61 are arranged side by side, and the suction nozzle 61 should be arranged between the guide wheel 71 and the material baffle plate 31. When the corrugated cardboard is transported to the bottom of the positioning frame 5, its surface is dusted immediately. The size of the suction nozzle 61 should be arranged according to actual use requirements and as close to the corrugated surface as possible. The top of the suction nozzle 61 extends upward and finally forms an exhaust pipe on the top surface of the Anzuhang board. Multiple exhaust pipes are connected by a silicone hose with a multi-branch structure, and the other end of the pipe is connected to the exhaust fan 62 arranged on one side of the positioning frame 5.

[0039] In the actual production process, corrugated cardboard is divided into various specifications and sizes. Therefore, some multi-layer corrugated cardboards need to properly adjust the height of their baffle plates 31. Therefore, a slot can be set on the fixed frame 3, and a screw rod 56 is set inside the slot. When the two ends of the baffle plate 31 are inserted into the slot, the screw rod 56 penetrates it, so as to use the threaded structure to adjust the height of the baffle plate 31, ensuring that the conveying roller 2 can only convey one piece of corrugated cardboard at a time, making its automatic loading more convenient.

[0040] In the actual production process, some corrugated cardboards with larger or smaller surface areas may be encountered, and the distance between the two sides and the center may change. At the same time, it is necessary to ensure that the same distance is maintained between each two adjacent mounting plates 52. Therefore, a screw rod 56 is arranged inside the slide groove 51. The screw rod 56 adopts a double-thread structure and passes through the ends of the mounting plates 52 on the left and right sides respectively. At the same time, a servo motor 53 is arranged inside the slide groove 51 and is transmission-connected to one end of the screw rod 56, so that the threaded structure is used to drive the mounting plates 52 on the left and right sides to move relative to or back to each other, thereby realizing the function of adjusting the spacing.

[0041] The above distance adjustment function can also be replaced by other devices, for example, electric wheels are provided at both ends of each mounting plate 52, and the electric wheels are adapted to the slide groove 51, so as to facilitate remote control of the distance between the mounting plates 52.

[0042] In addition, different corrugated cardboard models can withstand different pressures. Therefore, in actual use, it is also necessary to pay attention to the height of the positioning frame 5 to avoid excessive pressure causing depressions on the surface of the corrugated cardboard and affecting production quality.

[0043] Based on the above requirements, a pressure sensor 54 should also be provided inside the mounting plate 52. The pressure sensor 54 can be of the AXCX series by Huamei Aotong or the U5600 wireless pressure sensor 54, and it is arranged directly above the roller. When the guide wheel 71 contacts the top surface of the corrugated cardboard, the pressure sensor 54 detects the pressure and transmits the data in real time through a wire to the display 55 arranged on one side of the positioning frame 5. The staff can adaptively adjust the height of the positioning frame 5 and whether the positioning frame 5 is in a horizontal state by observing the displayed pressure.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the technical solutions of the embodiments of the present invention.
