Description

Technical Field

[0001] This invention belongs to the field of decorative paper processing technology, and specifically relates to a decorative paper packaging device and method. Background Technology

[0002] Decorative paper is an essential raw material in many building materials products, such as low-pressure and high-pressure boards used in furniture and cabinets, as well as fireproof boards and flooring. In the product structure, decorative paper is placed under the surface paper, primarily serving to provide decorative patterns and to cover and prevent the adhesive from seeping through. This layer requires the paper to have good opacity, impregnation properties, and printability. Decorative paper needs a smooth surface, good absorbency, and adaptability. After production, decorative paper needs to be packaged for later sale.

[0003] For example, a patent application with publication number CN216035298U discloses a packaging device for decorative paper, including a base plate, a lower plate above the base plate, support rods fixed between the lower plate and the base plate at the four corners of the bottom, a plurality of slots spaced apart above the lower plate, and lower rollers rotatably connected in each slot, a side connecting plate fixed on one side of the base plate, a sleeve rod fixed on one side of the side connecting plate, packaging paper sleeved on the sleeve rod and placed above the lower rollers, decorative paper placed on top of the packaging paper, a cutting mechanism on one side of the lower plate, upper plates on both sides above the lower plate, and side plates fixed on both sides below the upper plates. By placing the decorative paper to be packaged on the packaging paper and then pulling and rolling the decorative paper and packaging paper together, the paper can be packaged.

[0004] In existing decorative paper packaging equipment, the size of the rolled decorative paper can only be estimated based on the winding time of the roll during the rolling process. This can lead to over- or under-winding of the rolled decorative paper, which can easily result in waste during the use of the decorative paper. Summary of the Invention

[0005] The purpose of this invention is to address the problems of the prior art by providing a decorative paper packaging device and method.

[0006] A decorative paper packaging device includes a processing table, a cardboard roller, and a mounting frame. The processing table is provided with support feet and through holes. The cardboard roller is used to wind up decorative paper. The mounting frame is used to mount the cardboard roller. Side plates are symmetrically arranged on the processing table, and the mounting frame is mounted on the side plates. A main motor for driving the cardboard roller to rotate is installed on one side of one of the side plates. The rotation of the cardboard roller winds the decorative paper onto the cardboard roller. An auxiliary shaft is also installed between the symmetrically arranged side plates. The side plates are provided with a moving groove. A support plate is installed on the side of the side plate where the main motor is not installed. A threaded cylinder is threadedly connected to the auxiliary shaft. A measuring disc is installed on the threaded cylinder. The measuring disc is provided with scale lines. One end of the auxiliary shaft passes through the moving groove and extends to the outside of the side plate. A displacement cylinder is installed on the support plate. A connecting collar is installed on the displacement cylinder. The connecting collar is sleeved on the auxiliary shaft. The displacement cylinder causes the auxiliary shaft to move within the moving groove.

[0007] Furthermore, the mounting frame is equipped with multiple limiting rods to limit the position of the cardboard roller. The mounting frame is also provided with a feeding notch so that the cardboard roller can be taken out from the feeding notch after the decorative paper is wrapped and packaged. The mounting frame is provided with a circular hole, and a circular plate is installed in the circular hole. A hydraulic cylinder is installed between the circular plate and the circular hole, and the hydraulic cylinder pushes the circular plate to move.

[0008] Furthermore, an upper pressure plate and a lower bearing plate are installed on the circular plate. A push-pull cylinder is installed on the upper pressure plate and is connected to the circular plate. A limiting groove is provided in the upper pressure plate, and a connecting rod is installed in the limiting groove. A gravity block is installed at the bottom end of the connecting rod, and a pressure spring is connected between one side of the connecting rod and the limiting groove.

[0009] Furthermore, a push-pull cylinder two is installed at the bottom end of the lower support plate, a magnet one is installed at the bottom end of the gravity block, and a magnet two is installed on the lower support plate. The positions of the magnet one and the magnet two correspond to each other. When the magnet one and the magnet two are attracted together, the front and rear positions of the cardboard roller are fixed.

[0010] Furthermore, the side plate is also provided with a square groove, in which a telescopic cylinder is installed. A movable straight rod is installed at the bottom of the telescopic cylinder, and the movable straight rod moves up and down in the square groove.

[0011] Furthermore, the auxiliary shaft includes a left half shaft and a right half shaft, which are threadedly connected. Both the left half shaft and the right half shaft are threadedly connected to a threaded cylinder. The measuring disc is threadedly connected to the threaded cylinder. The threaded cylinder is provided with a locking part. A cardboard roller is sleeved on the auxiliary shaft. During processing, both ends of the cardboard roller are located in the locking part. The cardboard roller is also provided with an auxiliary component for supporting the cardboard roller. Both ends of the auxiliary component pass through the threaded cylinder.

[0012] Furthermore, the left half-shaft is provided with a groove, and the right half-shaft is provided with an extension, which is threadedly connected to the groove. Both the left and right half-shafts are provided with auxiliary rings, and multiple rollers are movably connected to the surface of the auxiliary rings. The surface of the rollers and the inner wall of the auxiliary component form point contact.

[0013] Furthermore, the diameter of the measuring disc on the threaded cylinder is different.

[0014] Furthermore, the auxiliary component is made of metal material, and the diameters at both ends of the auxiliary component are larger than the diameter of the middle part. The two ends of the auxiliary component are threadedly connected to the threaded cylinder, and the auxiliary component consists of two arc-shaped plates.

[0015] Based on the above-mentioned packaging apparatus for decorative paper, the present invention also proposes a method for packaging decorative paper, comprising the following steps:

[0016] When the auxiliary shaft and mounting bracket work simultaneously during packaging.

[0017] Step 1: Installing the cardboard roller on the mounting frame: The hydraulic cylinder pushes the circular plate towards the cardboard roller to fix the cardboard roller to the left and right positions. At this time, the cardboard roller is located between the upper pressure plate and the lower support plate. Push-pull cylinder one and push-pull cylinder two work to restrict the position of the cardboard roller through the upper pressure plate and the lower support plate. While the upper pressure plate moves down, the connecting rod restricts the front and rear position of the cardboard roller. After magnet one and magnet two are attracted, the position is locked. At this time, the feeding notch faces upward.

[0018] Step 2: Install the cardboard roller on the auxiliary shaft: Pass one end of the cardboard roller through the left half shaft, and pass the right half shaft through the cardboard roller and thread it to the left half shaft. Fit one end of the auxiliary shaft onto the connecting collar, rotate the threaded cylinder to engage the locking part with the cardboard roller, and rotate the measuring disc to make one side of the measuring disc fit against the locking part.

[0019] Step 3: A piece of decorative paper is wound from the moving rod onto the cardboard roller inside the mounting frame. The telescopic cylinder moves the moving rod upward to ensure the tension of the decorative paper.

[0020] Step 4: The decorative paper from the other side is wound from below the mounting frame onto the cardboard roller inside the auxiliary shaft. The displacement cylinder pushes the auxiliary shaft to adjust the tension of the decorative paper.

[0021] Step 5: The auxiliary shaft and the circular plate rotate synchronously. Observe the scale line on the measuring plate on the auxiliary shaft to know the thickness of the finished decorative paper at any time. Stop when the requirement is met. At this time, the thickness of the two cardboard rollers is the same.

[0022] Step Six: After completion, flip the feeding notch downwards; rotate the threaded cylinder in the opposite direction, copy the left and right half shafts, and rotate the auxiliary parts to complete the disassembly of the cardboard roller.

[0023] The beneficial effects of this invention are:

[0024] The cardboard rollers are installed using a mounting frame that can accommodate multiple cardboard rollers of different sizes. The mounting frame has a feeding notch for easy installation and removal of the cardboard rollers. It also has a measuring disc for detecting the thickness of the decorative paper on the cardboard rollers, thereby calculating the dimensions of the decorative paper for packaging. The operation is convenient.

[0025] An auxiliary shaft is also installed on the side plate. In addition to measuring the thickness of the decorative paper on the cardboard roller on the mounting frame, it has its own internal cardboard roller mounting structure for packaging operations. During the packaging process, the thickness is monitored at any time through the measuring disc. At the same time, the auxiliary shaft and the mounting shaft can work simultaneously. The packaging status of the mounting frame can be obtained by visually observing the status of the auxiliary shaft. The operation is simple and the packaging size is accurate.

[0037] Example 1

[0038] A decorative paper packaging device, such as Figure 1 As shown, it includes a processing table 12, a cardboard roller 31, and a mounting frame 6. The cardboard roller 31 is used to wind up decorative paper. By winding the decorative paper around the cardboard roller 31, it is easy to package and transport the decorative paper. The cardboard roller 31 is made of cardboard and can be reused.

[0039] The bottom of the processing table 12 is equipped with a support leg 11. Side plates 2 are symmetrically arranged on the processing table 12. The mounting frame 6 is installed on the side plate 2. The mounting frame 6 is used to install the cardboard roller 31. One of the side plates 2 is equipped with a main motor 1 for driving the cardboard roller 31 to rotate. The mounting frame 6 is provided with a clamping structure for clamping the cardboard roller 31. The main motor 1 passes through the mounting frame 6 and is connected to the clamping structure, so that the cardboard roller 31 rotates together with the mounting frame 6. The decorative paper is wrapped around the cardboard roller 31 by the rotation of the cardboard roller 31.

[0040] like Figure 3 As shown, the mounting frame 6 has a circular hole 20, and a circular plate 21 (clamping structure) is installed in the circular hole 20. A hydraulic cylinder 17 is installed between the circular plate 21 and the circular hole 20. Specifically, the hydraulic cylinder 17 is installed on the bottom wall of the circular hole 20. The hydraulic cylinder 17 pushes the circular plate 21 to move, and the circular plate 21 completes the clamping of the cardboard roller 31.

[0041] like Figure 3 and Figure 4As shown, the mounting frame 6 has multiple limiting rods 39 distributed within the same virtual semicircle concentric with the cardboard roller 31. The distance between two adjacent limiting rods is less than the diameter of the cardboard roller 31, but the distance between the two outermost limiting rods is greater than the diameter of the cardboard roller 31, which facilitates limiting the position of the cardboard roller 31. For example, if three limiting rods are provided, the first distance from the middle limiting rod to the two limiting rods on its left and right sides is equal, and this first distance is less than the diameter of the cardboard roller 31. At the same time, since the two first distances are equal, the tension of the decorative paper can be increased by the limiting rods 39 during the packaging process, and foreign objects adsorbed on the decorative paper can also be scraped off, preventing foreign objects from sticking to the surface of the decorative paper and affecting its quality. The mounting frame 6 is also provided with a feeding notch 38 extending along the length direction, so that the cardboard roller 31 can be taken out from the feeding notch 38 after the decorative paper is wrapped and packaged. During measurement, rotate the mounting bracket 6 so that the material feeding notch 38 faces the auxiliary shaft 40, and the axes of the middle limiting round rod, the auxiliary shaft 40 and the mounting bracket 6 are all located in the same virtual plane.

[0042] When the cardboard roller 31 is placed inside the mounting frame 6, the feeding notch 38 faces upwards; conversely, after the decorative paper on the cardboard roller 31 is packaged, the feeding notch 38 faces downwards. To facilitate the orientation of the feeding notch 38 on the mounting frame 6, the mounting frame 6 is threadedly connected to the side plate 2. The mounting frame 6 is rotated manually. After packaging, the orientation of the feeding notch 38 is downwards, i.e., the orientation of the feeding notch 38 is directly opposite the processing table 12. Figure 1 As shown, the processing table 12 is provided with a through hole 13. A robotic arm can be installed at the through hole 13 to complete the unloading of the packaged decorative paper.

[0043] like Figure 1 and Figure 2 As shown, an auxiliary shaft 40 is installed between the symmetrically arranged side plates 2. The side plates 2 are provided with a moving groove 5. A support plate 7 is installed on the side of the side plate 2 where the main motor 1 is not installed. A displacement cylinder 14 is installed on the support plate 7. A connecting collar 15 is installed on the displacement cylinder 14. One end of the auxiliary shaft 40 passes through the moving groove 5 and extends to the outside of the side plate 2. The connecting collar 15 is sleeved on the auxiliary shaft 40. The displacement cylinder 14 causes the auxiliary shaft 40 to move within the moving groove 5.

[0044] A threaded cylinder 30 is threaded onto the auxiliary shaft 40. The position of the measuring disc 3 can be adjusted by rotating the threaded cylinder 30. The measuring disc 3 is mounted on the threaded cylinder 30. Several graduation lines 4 are provided on the side wall of the measuring disc 3 to measure the thickness of the decorative paper on the cardboard roller. During measurement, the side wall of the measuring disc 3 with graduation lines is attached to both ends of the decorative paper. By observing the graduation lines 4, the thickness of the rolled decorative paper can be determined.

[0045] During processing, the auxiliary shaft 40 is far away from the mounting frame 6. During measurement, the auxiliary shaft 40 is pulled towards the mounting frame 6 by the displacement cylinder 14. At this time, the material feeding notch 38 of the mounting frame 6 faces the auxiliary shaft 40. The decorative paper is aligned with the scale 3, and the thickness of the decorative paper is directly read according to the scale on the scale 3, thereby calculating the packaging size of the decorative paper.

[0046] like Figure 1 As shown, in order to adjust the tension of the decorative paper, a square groove 10 is also provided on the side plate 2. A telescopic cylinder 8 is installed in the square groove 10. A moving rod 9 is installed at the bottom of the telescopic cylinder 8. The moving rod 9 moves up and down in the square groove 10. When working, the decorative paper is passed around the moving rod 9. The tension of the decorative paper is adjusted by adjusting the height of the moving rod 9 through the telescopic cylinder 8.

[0047] Example 2

[0048] Based on the above embodiment one, as follows Figure 3 As shown, an upper pressure plate 18 and a lower support plate 16 are installed on the circular plate 21. A push-pull cylinder 19 is installed on the upper pressure plate 18. The push-pull cylinder 19 is connected to the circular plate 21. The upper pressure plate 18 is moved up and down by the push-pull cylinder 19, and the position of the lower support plate 16 is fixed. The movement of the upper pressure plate 18 limits the up and down movement of the cardboard roller 31. The symmetrically arranged circular plates 21 limit the left and right movement of the cardboard roller 31. The cardboard roller 31 is placed in the mounting frame 6. After the hydraulic cylinder 17 pushes the circular plate 21 towards the cardboard roller 31 to clamp it, the push-pull cylinder 19 pushes the upper pressure plate 18 down to further clamp the cardboard roller 31.

[0049] Because the cardboard roller 31 rotates during packaging, therefore, Figure 3 , Figure 5 and Figure 6 As shown, the upper pressure plate 18 is provided with a limiting groove 25, and a connecting rod 27 is installed in the limiting groove 25. The connecting rod 27 limits the front and rear movement of the cardboard roller 31.

[0050] A gravity block 23 is installed at the bottom of the connecting rod 27 to facilitate the stable movement of the connecting rod 27. In order to further clamp cardboard rollers 31 of different diameters, the upper pressure plate 18 and the connecting rod 27 are set to be adjustable. A pressure spring 24 is connected between one side of the connecting rod 27 and the limiting groove 25. When clamping a cardboard roller with a larger diameter, as the upper pressure plate 18 moves down, the cardboard roller 31 applies a squeezing force to the connecting rod 27, pushing the connecting rod 27 outward. The pressure spring 24 is compressed and contracts. Through the pressure spring 24 and the connecting rod 27, a reverse force is applied to the cardboard roller, thereby limiting the position of the cardboard roller.

[0051] In order to lock the position of gravity block 23, a magnet 26 is installed at the bottom of gravity block 23 and a magnet 28 is installed on the lower support plate 16. The positions of magnet 26 and magnet 28 correspond to each other. When magnet 26 and magnet 28 are attracted together, the front and rear positions of cardboard roller 31 are fixed.

[0052] A push-pull cylinder 22 is installed at the bottom of the lower support plate 16, which makes the upper and lower positions of the lower support plate 16 adjustable, thereby changing the center position of the cardboard roller and preventing the cardboard roller from deviating to the side where the limiting rod 39 is located, which would cause the limiting rod 39 to restrict the thickness of the decorative paper.

[0053] The other components and principles in this embodiment are the same as in Embodiment 1.

[0054] Example 3

[0055] Based on the above embodiment two, in order to more intuitively obtain the thickness of the decorative paper on the cardboard roller, such as Figures 7-9 As shown, the auxiliary shaft 40 includes a left half shaft 29 and a right half shaft 34, which are threaded together. The auxiliary shaft 40 adopts a splicing connection. The left half shaft 29 is provided with a groove 37, and the right half shaft 34 is provided with an extension 33. The extension 33 is threadedly connected to the groove 37 to facilitate the installation and removal of the cardboard roller. During installation, the left half shaft 29 and the right half shaft 34 are not connected. First, the cardboard roller is placed on the left half shaft 29, and then the right half shaft 34 is threaded through the cardboard roller and connected to the left half shaft 29.

[0056] Both the left half-shaft 29 and the right half-shaft 34 are threadedly connected to threaded cylinders 30. The measuring disc 3 and the threaded cylinder 30 are threadedly connected. The threaded cylinder 30 is provided with a locking part 41. The auxiliary shaft 40 is fitted with a cardboard roller 31. During processing, both ends of the cardboard roller 31 are located in the locking part 41. After the cardboard roller is initially fitted onto the auxiliary shaft 40, the threaded cylinder 30 is rotated so that the locking part 41 of the threaded cylinder 30 engages with the cardboard roller 31. Then, the measuring disc 3 is rotated again so that one end of the measuring disc 3 is aligned with one side of the locking part 41 so that the winding thickness of the decorative paper can be observed at any time during the winding action.

[0057] As a further option, the auxiliary shaft 40 and the mounting frame 6 can perform decorative paper packaging operations simultaneously, or they can be performed separately. During packaging, the thickness of the decorative paper winding on the cardboard roller 31 on the auxiliary shaft 40 can be monitored at any time by the measuring disc 3, thereby controlling the winding status of the mounting frame 6. This makes the operation convenient and makes the dimensions of the packaged decorative paper more accurate.

[0058] To ensure that the middle part of the cardboard roller 31 is subjected to uniform force, an auxiliary component 35 is provided inside the cardboard roller 31 to support the cardboard roller 31. The auxiliary component 35 is made of metal material to ensure reliable support.

[0059] To facilitate the installation and disassembly of the auxiliary component 35, the auxiliary component 35 consists of two arc-shaped plates. At the same time, auxiliary rings 32 are provided on both the left half-shaft 29 and the right half-shaft 34, and multiple rollers 36 are movably connected to the surface of the auxiliary rings 32. The surface of the rollers 36 and the inner wall of the auxiliary component 35 form point contact, reducing the friction between the auxiliary rings 32 and the auxiliary rings 34.

[0060] The auxiliary component 35 passes through the threaded cylinder 30 at both ends. The diameter of the auxiliary component 35 at both ends is larger than the diameter of the middle part. The auxiliary component 35 is threadedly connected to the threaded cylinder 30 at both ends, which facilitates manual installation and disassembly of the auxiliary component 35.

[0061] The measuring disc 3 on the threaded cylinder 30 has different diameters, which can measure decorative paper of various thicknesses.

[0062] The other components and principles in this embodiment are the same as in Embodiment 2.

[0063] Based on the above-mentioned packaging apparatus for decorative paper, the present invention also proposes a method for packaging decorative paper, comprising the following steps:

[0064] When the auxiliary shaft and mounting bracket work simultaneously during packaging.

[0065] Mounting bracket 6 installs cardboard roller 31: Hydraulic cylinder 17 pushes circular plate 21 toward cardboard roller 31 to fix the left and right positions of cardboard roller 31. At this time, cardboard roller 31 is located between upper pressure plate 18 and lower support plate 16. Push-pull cylinder 19 and push-pull cylinder 22 work to restrict the position of cardboard roller 31 through upper pressure plate 18 and lower support plate 16. While upper pressure plate 18 moves down, connecting rod 27 restricts the front and rear positions of cardboard roller 31. After magnet 1 26 and magnet 2 28 are attracted, the position is locked. At this time, the feeding notch 38 faces upward.

[0066] Auxiliary shaft 40 is used to install cardboard roller 31: one end of cardboard roller 31 passes through left half shaft 29, and right half shaft 34 passes through cardboard roller 31 and is threadedly connected to left half shaft 29. One end of auxiliary shaft 40 is sleeved on connecting collar 15. The threaded cylinder 30 is rotated to make the engaging part 41 engage with cardboard roller 31. The measuring disk 3 is rotated so that one side of the measuring disk 3 is in contact with one side of the engaging part 41.

[0067] A piece of decorative paper is wound from the moving rod 9 onto the cardboard roller inside the mounting frame 6, and the telescopic cylinder 8 moves the moving rod 9 upward to ensure the tension of the decorative paper;

[0068] The decorative paper at another location is wound from below the mounting frame 6 onto the cardboard roller inside the auxiliary shaft 40, and the displacement cylinder 14 pushes the auxiliary shaft 40 to adjust the tension of the decorative paper;

[0069] The auxiliary shaft 40 and the circular plate 21 rotate synchronously. By observing the scale line on the measuring disk 3 on the auxiliary shaft 40, the thickness of the finished decorative paper can be known at any time. Once the requirement is met, the rotation stops. At this time, the thickness of the two cardboard rollers is the same, resulting in high packaging efficiency.

[0070] After completion, the feeding notch 38 is flipped downwards; the threaded cylinder 30 is rotated in the opposite direction to disassemble the left half shaft 29 and the right half shaft 34, and the auxiliary part 35 is rotated to complete the disassembly of the cardboard roller.

[0071] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention 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 invention should be included within the protection scope of the present invention.
