Description

Technical Field

[0001] This utility model relates to the field of cardboard box technology, and in particular to a cardboard flattening device for cardboard processing. Background Technology

[0002] Cardboard boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc., and they come in various specifications and models. Cardboard boxes commonly have three or five layers, while seven-layer boxes are less common. Each layer consists of linerboard, corrugated paper, core paper, and face paper. Linerboard and face paper can be made of kraft paper or kraft paper, while the core paper is made of corrugated paper. The colors and textures of different types of paper are different, and the colors and textures of paper produced by different manufacturers are also different.

[0003] For example, Chinese Utility Model Patent Application No. 202320935062.6 discloses a cardboard flattening device for cardboard box processing, including: a conveyor belt, a baffle fixedly connected to one side of the conveyor belt, a bracket fixedly connected to the top of the baffle, a pressing shaft arranged inside the bracket, pressing rollers arranged on the outer surface of the pressing shaft, a connecting shaft arranged inside the top of the bracket, a handle plate fixedly connected to one end of the connecting shaft, a fixed handle arranged inside the handle plate, a fixing hole arranged on one side of the top of the bracket, and a belt fixedly connected to the outer surface of the connecting shaft. This utility model improves a cardboard flattening device for cardboard box processing by using a crank handle at the top of the bracket to drive the belt, which raises or lowers the pressing shaft, thereby extending or shortening the distance between the pressing rollers and the conveyor belt, thus controlling the pressing rollers to press cardboard of different thicknesses. It has the advantage of wide applicability and effectively solves the problems and shortcomings of existing devices.

[0004] The aforementioned patent uses pressing rollers to flatten the cardboard during use. However, in actual production, due to the poor processing and storage environment in small factories, particles can easily enter the gaps between cardboards during the transfer and stacking process. When these cardboards containing particles are flattened, the particles will embed themselves in the cardboard during the flattening process of the pressing rollers, causing indentations or damage to the surface of the cardboard. This not only affects the appearance of the cardboard but also leads to a decrease in the yield rate. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 1-5 This utility model provides a cardboard flattening device for cardboard processing: it includes a frame 1, a conveying mechanism between the front and back sides of the inner wall of the frame 1, a flattening mechanism, a lifting mechanism and a limiting mechanism at the top of the frame 1, a filter box 2 at the bottom of the frame 1, a filter plate 3 inside the filter box 2, a dust collector 4 at the back of the filter box 2, a dust collection pipe 5 fixedly connected to the front of the filter box 2, a dust collection hood 6 fixedly connected to the top of the frame 1, the other end of the dust collection pipe 5 fixedly connected to the dust collection hood 6, two mounting frames 7 fixedly connected to the top of the frame 1, an upper scraper 8 slidably connected between the two mounting frames 7, and a lower scraper 9 fixedly connected between the front and back sides of the inner wall of the frame 1.

[0020] The conveying mechanism includes a drive motor 10, a driven roller 11, and two transmission rollers 12. The drive motor 10 is fixedly installed on the front of the frame 1. The output end of the drive motor 10 is fixedly connected to a drive roller 29. The driven roller 11 and the two transmission rollers 12 are rotatably installed between the front and back sides of the inner wall of the frame 1. The drive roller 29 and one of the transmission rollers 12 are connected by a conveyor belt 13. The driven roller 11 and the other transmission roller 12 are connected by a conveyor belt 14. Rotating wheels 15 are fixedly sleeved on the outer surface of the two transmission rollers 12. The two rotating wheels 15 are connected by a belt 16.

[0021] The flattening mechanism includes a U-shaped frame 17 fixedly installed on the top of the frame 1. A hydraulic telescopic rod 18 is fixedly installed on the top of the U-shaped frame 17. A mounting frame 19 is fixedly connected to the telescopic end of the hydraulic telescopic rod 18. A second drive motor 20 is fixedly installed on the front side of the mounting frame 19. A flattening roller 21 is fixedly connected to the output end of the second drive motor 20. The flattening roller 21 is rotatably installed between the front and back sides of the inner wall of the mounting frame 19. The mounting frame 19 is slidably connected to the U-shaped frame 17.

[0022] The lifting mechanism includes a second mounting frame 22 fixedly installed on the top of the frame 1. A threaded rod 23 is rotatably connected between the top and bottom of the inner wall of the second mounting frame 22. A knob 24 is fixedly connected to the top of the threaded rod 23. A threaded sleeve 25 is threadedly connected to the outer surface of the threaded rod 23. A connecting rod 26 is fixedly connected to the upper part of the threaded sleeve 25. One end of the connecting rod 26 is fixedly connected to one end of the upper scraper 8. By using the lifting mechanism, upper scraper 8, and lower scraper 9 in combination, the height of the upper scraper 8 can be adjusted according to the thickness of the cardboard to be flattened, ensuring that the upper scraper 8 can always be in contact with the upper surface of the cardboard to be flattened. This allows the upper scraper 8 and the lower scraper 9 to clean the floating dust on both sides of the cardboard, improving the cleanliness of the outer surface of the cardboard.

[0023] The limiting mechanism includes a mounting frame 27 fixedly installed on the top of the frame 1, a limiting plate 28 slidably connected to the mounting frame 27, and the limiting plate 28 fixedly connected to one end of the connecting rod 26; By using the combined structure of dust collector 4, dust hood 6, dust pipe 5 and limiting mechanism, the particles in the cardboard interlayer pushed onto the conveyor belt 14 can be removed by suction, preventing them from being trapped in the gaps between the cardboard during the flattening operation, thus avoiding indentations or surface damage. This improves the yield of flattened cardboard. At the same time, the limiting plate 28 limits the cardboard when the dust collector 4 is extracting particles from the cardboard interlayer, preventing the cardboard from tilting or shifting due to instantaneous suction, thus improving the stability of the cardboard during particle extraction.

[0024] Working principle: When the cardboard needs to be flattened, the operator first pushes the cardboard to be flattened onto the conveyor belt 14. Then, according to the thickness of the cardboard, the height of the limiting plate 28, the upper scraper 8 and the flattening roller 21 are adjusted. By turning the knob 24, the threaded rod 23 is rotated, so that the threaded sleeve 25 drives the connecting rod 26, the upper scraper 8 and the limiting plate 28 to descend synchronously to the preset height. At the same time, the hydraulic telescopic rod 18 is activated. The telescopic end of the hydraulic telescopic rod 18 drives the mounting plate and the flattening roller 21 to descend to the required flattening height. After the height setting is completed, drive motor 10 is started. The output of drive motor 10 drives the active roller 29 to rotate. The active roller 29 drives the adjacent transmission roller 12 to rotate through conveyor belt 13. The transmission roller 12 then drives another transmission roller 12 to rotate through belt 16. In turn, the driven roller 11 is driven to rotate through conveyor belt 24, so that conveyor belt 214 drives the cardboard to be flattened to move upward towards scraper 8. Meanwhile, during the conveying process, the dust collector 4 creates a negative pressure environment in the gap between the cardboard through the dust collection pipe 5 and the dust collection hood 6, extracting the particulate matter in the gap between the cardboard to be flattened. After being filtered by the filter plate 3, the particulate matter is collected in the filter box 2. At the same time, the limiting plate 28 plays a role in stabilizing the cardboard during this process, preventing the cardboard to be flattened from tilting due to suction on one side. When the cardboard is conveyed to the point of contact with the upper scraper 8 and the lower scraper 9, the upper scraper 8 and the lower scraper 9 clean both sides of the cardboard respectively. The cleaned cardboard to be flattened is conveyed onto the conveyor belt 13 by the second conveyor belt 14 and continues to be conveyed toward the flattening roller 21. When it moves to the bottom of the flattening roller 21, the second drive motor 20 is started. The output end of the second drive motor 20 drives the flattening roller 21 to rotate and flatten the cardboard to be flattened under the preset pressure.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
