Description
Technical Field
[0001] This invention relates to the technical field of waterproof membrane production equipment, specifically to a waterproof membrane paper packaging machine and packaging method. Background Technology
[0002] Waterproof membrane is a type of membrane commonly used in existing technologies, including extrusion molding and compression molding. After production, it often needs to be packaged with wrapping paper before leaving the factory. Current packaging usually uses automatic packaging machines, which can automatically complete the packaging work.
[0003] Existing packaging machines typically use a rolling and pasting method when wrapping the waterproof membrane with wrapping paper. However, when the wrapping paper is pasted onto the surface of the membrane, it may be skewed, misaligned, or wrinkled. This causes subsequent wrapping paper to also be skewed during rolling. On the one hand, incomplete coverage leads to wear and tear on the exposed waterproof membrane. On the other hand, skewed wrapping paper results in loose packaging, which may cause the wrapping paper to fall off, directly affecting the integrity of the packaging and requiring rework, thus reducing efficiency. Based on these problems, a new packaging equipment is needed. Summary of the Invention
[0004] This invention proposes a waterproof roll paper packaging machine and packaging method, which solves the problem that packaging paper in existing packaging equipment is prone to skewing and wrinkling, resulting in reduced packaging quality.
[0005] The technical solution of the present invention is as follows: A waterproof roll paper packaging machine includes a frame and a packaging paper slitting device, a packaging paper conveying device, and a packaging paper wrapping device mounted on the frame. The packaging paper wrapping device includes a wrapping belt, a positioning roller, a tension roller, a drive roller, and a floating roller. The wrapping belt is sleeved on the positioning roller, the tension roller, the drive roller, and the floating roller. The packaging paper wrapping device includes a limiting stop roller. The area between the positioning roller and the floating roller is a roll material placement position. The floating roller and the drive roller are inclined. Both the limiting stop roller and the floating roller are movably mounted on the frame to limit the roll material. The wrapping belt at the floating roller is tangent to the conveying direction of the packaging paper conveying device.
[0006] The frame is provided with an arc-shaped groove. The packaging paper wrapping device also includes a floating drive cylinder and a connecting rod. One end of the connecting rod is hinged to the frame, and the floating roller is located at the other end of the connecting rod. The floating drive cylinder drives the floating roller to move along the arc-shaped groove.
[0007] The packaging paper slitting device includes a paper roll, a traction conveying roller, an upper pressure metering roller, and a cutting mechanism. One end of the paper roll passes between the traction conveying roller and the upper pressure metering roller, which are arranged opposite each other. The cutting mechanism is located on the exit side of the traction conveying roller.
[0008] The cutting mechanism includes a cutting track, a cutting motor, a cutting blade, and a glue brush head. The cutting motor is slidably mounted on the cutting track, the cutting blade is mounted on the output end of the cutting motor, and the glue brush head has two glue brushing ends with a gap. The cutting blade is located in the middle of the gap between the glue brush heads.
[0009] The packaging paper conveying device includes a conveyor frame and a conveyor belt mounted on the conveyor frame. A conveyor roller is installed inside the conveyor belt. One end of the conveyor frame is hinged to the machine frame. The packaging paper conveying device also includes an adjusting cylinder connected to the conveyor frame to adjust the angle of the conveyor frame relative to the wrapping belt at the floating roller.
[0010] A method for packaging waterproof membrane, applied to the packaging machine of any of the above-mentioned solutions, the packaging method comprising the following steps: Adjust the floating roller to the first position, place the roll material onto the wrapping belt between the positioning roller and the floating roller, so that the outlet end of the packaging paper conveying device is tangent to the side of the wrapping belt near the floating roller, and the limiting stop roller limits the roll material. The packaging paper slitting device cuts the packaging paper to a fixed length. The packaging paper, after being cut to a fixed length, is conveyed by a packaging paper conveying device, with one end of the cut packaging paper being conveyed between the roll material and the wrapping belt. As the wrapping belt starts rotating, the floating roller moves from the first position to the second position, causing the wrapping belt to stick the wrapping paper onto the roll material, and continues to roll the roll material once to complete the full wrapping. The floating roller moves from the second position to the third position, the limiting roller is released from its limit, and the packaged roll slides down the floating roller to the drive roller to complete the unloading.
[0011] The working principle and beneficial effects of this invention are as follows: This invention discloses a waterproof roll paper packaging machine. A paper slitting device is installed on the frame to slit the paper. The slit paper is then conveyed to a wrapping device via a paper slitting and conveying device. The wrapping device neatly and flatly attaches one end of the slit paper to the side wall of a rolled waterproof roll. The wrapping device then rotates the rolled waterproof roll, thus wrapping the waterproof roll with the paper. The other end is then properly wrapped. The wrapping device supports the wrapping belt via a positioning roller, a tension roller, a drive roller, and a floating roller. The rolled waterproof roll is positioned between the positioning roller and the floating roller. The floating roller is adjusted to ensure that the conveying direction of the paper conveying device (i.e., the paper outlet) is tangent to the wrapping belt at the floating roller's position, allowing the slit paper to wrap the waterproof roll. Using this solution, the paper wrapping is smooth, the pasting is wrinkle-free, and the absence of wrinkles or skew improves the bonding strength, thereby improving packaging quality.

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0015] like Figures 1-2As shown in the figure, this embodiment proposes a waterproof roll paper packaging machine. The waterproof roll paper packaging machine includes a frame 1 and a packaging paper slitting device 2, a packaging paper conveying device 3, and a packaging paper wrapping device 4, which are arranged on the frame 1. The packaging paper wrapping device 4 includes a wrapping belt 5, a positioning roller 6, a tensioning roller 7, a drive roller 8, and a floating roller 9. The wrapping belt 5 is sleeved on the positioning roller 6, the tensioning roller 7, the drive roller 8, and the floating roller 9. The packaging paper wrapping device 4 includes a limiting stop roller 10. The roll material placement position is between the positioning roller 6 and the floating roller 9. The floating roller 9 and the drive roller 8 are inclined. The limiting stop roller 10 and the floating roller 9 can be movably arranged on the frame 1 to limit the roll material. The wrapping belt 5 at the floating roller 9 can be tangent to the conveying direction of the packaging paper conveying device 3.
[0016] In this embodiment, a waterproof roll paper packaging machine is disclosed. A packaging paper slitting device 2 is set on the frame 1 to slit the paper. The slit packaging paper is conveyed to the packaging paper wrapping device 4 through the packaging paper slitting and conveying device. The packaging paper wrapping device 4 neatly and flatly attaches one end of the slit packaging paper to the side wall of the rolled waterproof roll. Then, the packaging paper wrapping device 4 rotates the rolled waterproof roll, thereby wrapping the waterproof roll with the packaging paper. The other end is pasted to complete the wrapping. The packaging paper wrapping device 4 supports the wrapping belt 5 through the positioning roller 6, tension roller 7, drive roller 8 and floating roller 9. The rolled waterproof roll is placed between the positioning roller 6 and the floating roller 9. The limiting stop roller 10 can be limited by a cylinder. The floating roller 9 adjusts the floating position so that the conveying direction of the packaging paper conveying device 3 at the position of the floating roller 9 is tangent to the paper outlet, so that the slit packaging paper can wrap the waterproof roll.
[0017] The frame 1 is provided with an arc-shaped groove 11. The packaging paper wrapping device 4 also includes a floating drive cylinder 12 and a connecting rod 13. One end of the connecting rod 13 is hinged to the frame 1, and the floating roller 9 is provided at the other end of the connecting rod 13. The floating drive cylinder 12 drives the floating roller 9 to move along the arc-shaped groove 11.
[0018] In this embodiment, the floating roller 9 can move on the frame 1 to adjust the shape of the wrapping belt 5, located between the floating roller 9 and the positioning roller 6, when carrying the unwound roll material. This allows adjustment of the wrapping angle of the wrapping belt 5 around the waterproof roll material, ensuring the wrapping angle is suitable for the packaging paper to be fed tangentially into the waterproof roll material in the initial wrapping stage. This ensures the end of the packaging paper is flat and aligned before being fed into the waterproof roll material. Then, the floating roller 9 adjusts its position, causing the wrapping belt 5 to adjust its wrapping angle. First, the end of the packaging paper is pasted onto the surface of the waterproof roll material, and then it is wrapped by rotating the belt. Specifically, an arc-shaped groove 11 is provided on the frame 1. The direction of the arc-shaped groove 11 allows the floating roller 9 to adjust the shape of the wrapping belt 5 to meet the positional relationship of the aforementioned equipment operation to complete the wrapping. A connecting rod 13 is hinged to the frame 1, supporting the floating roller 9. A floating drive cylinder 12 drives the floating roller 9 to adjust its position within the arc-shaped groove 11.
[0019] The packaging paper slitting device 2 includes a paper roll 14, a traction conveying roller 15, an upper pressure metering roller 16, and a cutting mechanism. One end of the paper roll 14 passes between the traction conveying roller 15 and the upper pressure metering roller 16, which are arranged opposite to each other. The cutting mechanism is located on the exit side of the traction conveying roller 15.
[0020] In this embodiment, the packaging paper is carried on the paper roll 14, with one end passing between the traction conveying roller 15 and the upper pressure metering roller 16. The traction conveying roller 15 provides conveying force to the paper roll 14, while the upper pressure metering roller 16 presses down on the packaging paper to ensure conveying friction. On the other hand, the upper pressure metering roller 16 is connected to a metering encoder based on the number of rotations to calculate the conveying length. When the target length is reached, the cutting mechanism cuts the packaging paper at the exit side of the traction conveying roller 15 to achieve fixed-length slitting.
[0021] The cutting mechanism includes a cutting track 17, a cutting motor 18, a cutting blade 19, and a glue brush head 20. The cutting motor 18 is slidably mounted on the cutting track 17, the cutting blade 19 is mounted on the output end of the cutting motor 18, and the glue brush head 20 has two glue brushing ends with a gap. The cutting blade 19 is located in the middle of the gap of the glue brush head 20.
[0022] In this embodiment, the cutting mechanism specifically includes a cutting track 17 on the frame 1, which can be a linear guide rail. The cutting motor 18 is slidably mounted on the cutting track 17 via a movable seat. The cutting motor 18 is driven to move along the cutting track 17 by a telescopic drive. A cutting blade 19 is set at the output end of the cutting motor 18 to cut the packaging paper. A glue brush head 20 is installed at the end of the cutting motor 18 via a bracket. The glue brush head 20 is divided into two glue brushing ends with a gap in the middle to allow space for the cutting blade 19. The glue brush head 20 applies glue to both sides of the packaging paper on the cutting blade 19, so that both the tail end and the head end of the packaging paper are glued, which facilitates subsequent packaging.
[0023] The packaging paper conveying device 3 includes a conveying frame 21 and a conveying belt 22 disposed on the conveying frame 21. A conveying roller is disposed inside the conveying belt 22. One end of the conveying frame 21 is hinged to the frame 1. The packaging paper conveying device 3 also includes an adjusting cylinder 23, which is connected to the conveying frame 21 to adjust the angle of the conveying frame 21 relative to the wrapping belt 5 at the floating roller 9.
[0024] In this embodiment, the cut packaging paper falls onto the packaging paper conveying device 3. The conveying frame 21 is hinged to the machine frame 1. Rollers are installed on the conveying frame 21 to support the conveyor belt 22 and drive the roller 8 to rotate the conveyor belt 22 to convey the packaging paper on its surface. An adjusting cylinder 23 is also installed on the machine frame 1. One end of the adjusting cylinder 23 is connected to the conveying frame 21. The adjusting cylinder 23 can adjust the tilt angle of the conveying frame 21 by adjusting the extension length, so that when the packaging paper is fed into the wrapping belt 5 at the floating roller 9, the packaging paper is tangent to the wrapping belt 5, and the packaging paper feeding position is kept aligned.
[0025] A method for packaging waterproof roll material, applied to the packaging machine of any of the above embodiments, the packaging method comprising the following steps: Adjust the floating roller 9 to the first position, place the roll material onto the wrapping belt 5 between the positioning roller 6 and the floating roller 9, so that the outlet end of the packaging paper conveying device 3 is tangent to the side of the wrapping belt 5 near the floating roller 9, and limit the roll material with the limiting stop roller 10. The packaging paper slitting device 2 cuts the packaging paper to a fixed length. The packaging paper after being cut to a fixed length is conveyed by the packaging paper conveying device 3, and one end of the packaging paper after being cut to a fixed length is conveyed between the roll material and the wrapping belt 5. As the wrapping belt 5 starts to rotate, the floating roller 9 moves from the first position to the second position, so that the wrapping belt 5 sticks the wrapping paper to the roll material and continues to roll the roll material once to complete the full wrapping. The floating roller 9 moves from the second position to the third position, the limiting roller 10 is released from its limit, and the packaged roll slides down the floating roller 9 to the drive roller 8 to complete the unloading.
[0026] In this embodiment of the packaging method, when the waterproof membrane is placed in, the floating roller 9 adjusts its position to the first position. The first position refers to the position after the waterproof membrane is placed on the wrapping belt 5. After the limiting roller 10 limits the membrane, the wrapping belt 5, under the weight of the waterproof membrane, tilts at an angle tangential to the direction of the packaging paper conveying on the side closest to the floating roller 9. Then, the packaging paper is cut according to different cutting lengths set according to the different diameters of the waterproof membrane. The cut packaging paper is then conveyed to the contact position between the waterproof membrane and the wrapping belt 5. At this time, as the wrapping belt 5 rotates, the floating roller 9 moves from the second position to the third position. During the movement of the floating roller 9, the covering area of the wrapping belt 5 and the waterproof membrane gradually increases. The wrapping belt 5 presses and sticks the end of the packaging paper, and as the waterproof roll rotates, the wrapping surface of the wrapping belt on the packaging paper increases, improving the packaging quality. The second position refers to a point in the direction of movement of the floating roller 9 that can increase the expansion of the wrapping surface of the wrapping belt 5. The specific position of the second position can be set to increase the range of the wrapping surface as needed. After the waterproof roll is wrapped, the limiting roller is released, and the floating roller 9 moves from the second position to the third position. The waterproof roll slides from the floating roller 9 to the side of the drive roller 8 to complete the unloading. The third position refers to the position where the floating roller 9 is located after the limiting roller 10 is released, and the waterproof roll can roll from the floating roller 9 to the side of the drive roller 8 by gravity.
[0027] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. 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.
