Description

Technical Field

[0001] The present invention relates to the technical field of waterproof coiled material packaging equipment, in particular to a waterproof coiled material vertical rolling packaging device and a vertical rolling method. Background Art

[0002] Waterproof roll is a kind of roll commonly used in the existing technology. It is usually formed by extrusion and compression molding. After production, it often needs to be packaged with packaging film before it can be shipped out. The existing packaging usually uses automatic packaging machines, which can automatically complete the film packaging work.

[0003] Currently, waterproofing rolls are mostly rolled horizontally and then packaged horizontally. However, during the horizontal rolling process, if the speed of the winding device fluctuates, it is very easy to make it difficult to tightly wind the roll due to the weight of the roll during the winding process.

[0004] Because the reel is wound horizontally, the waterproofing membrane above the reel tends to move toward the axis of the reel under its own weight, while the waterproofing membrane below the reel tends to move away from the axis. Therefore, if the reeling and feeding speeds fluctuate, the waterproofing membrane on the reel can become untangled due to the different trends on the upper and lower sides of the reel, affecting the reeling effect.

[0005] Moreover, for the horizontal winding method, before packaging, in order to prevent the waterproof roll from becoming entangled with the winding roller during the packaging process, the roll must be bundled in front of the roller before packaging.

[0006] Therefore, the existing horizontal winding and packaging process not only has the problem of poor winding effect, but also has the problems of low packaging process efficiency and more steps. Summary of the Invention

[0007] One of the purposes of the present invention is to provide a vertical winding and packaging device for waterproof roll materials, so as to realize vertical winding and packaging of waterproof roll materials, and avoid the problem that the roll materials are difficult to wind tightly when the winding speed and the feeding speed fluctuate due to the weight of the roll materials.

[0008] A second object of the present invention is to provide a method for vertically rolling up a waterproofing coiled material, so as to achieve the purpose of vertically rolling up the coiled material and simultaneously quickly packaging the coiled material.

[0009] In order to achieve one of the above purposes, the present invention adopts the following technical means: A vertical winding and packaging device for waterproof coiled material, comprising: A vertically arranged storage cylinder with two through ends, wherein a rotating shaft is coaxially constructed in the storage cylinder, one end of the rotating shaft extends from the top end of the storage cylinder and is connected to the rotating end of the rotating motor, and a feeding channel is constructed on the side wall of the storage cylinder parallel to its axis; A clamping and limiting mechanism is provided in the storage cylinder and includes a clamping rod arranged around the axis of the storage cylinder, an end of the clamping rod facing the rotating shaft is configured with an abutment mechanism that moves linearly along the axis of the clamping rod, a damping mechanism that applies thrust to the abutment mechanism is provided in the clamping rod, and an end of the abutment mechanism is arranged to abut against the material wound around the rotating shaft; A pushing mechanism is coaxially arranged on the top side of the storage cylinder and is configured with a passage for the rotation shaft to pass through, and the side of the pushing mechanism facing away from the storage cylinder is connected to the telescopic motor via a connecting rod; The packaging and dividing mechanism is coaxially arranged at the bottom end of the storage tube, and includes a positioning tube coaxially fixedly connected to the bottom end of the storage tube, a cutting blade is installed on the inner wall of the positioning tube, and a packaging mechanism is coaxially detachably installed at the bottom end of the positioning tube.

[0010] Preferably, the side wall of the rotating shaft is provided with an embedding groove extending along its axis, the bottom end of the embedding groove is provided through the bottom end of the rotating shaft, and the embedding groove is aligned with the feed channel.

[0011] Furthermore, pressure rollers are installed at both horizontal ends of the feed channel, and the material to be wound passes between the two pressure rollers.

[0012] Furthermore, the clamping rod is installed on the inner wall of the storage tube, and a sliding cavity is constructed inside the clamping rod. A push rod serving as the abutment mechanism is slidably arranged in the sliding cavity. One end of the push rod is slidably arranged in the sliding cavity, and the other end of the push rod extends out of the sliding cavity and is rotatably installed with a ball.

[0013] Furthermore, the damping mechanism includes an electromagnet installed in the sliding cavity, and a permanent magnet installed at one end of the push rod located in the sliding cavity, and the magnetism of the opposite surfaces of the electromagnet and the permanent magnet are set to be the same.

[0014] Furthermore, the pressing rod is constructed with a ventilation channel that passes through its side wall and communicates with the sliding cavity.

[0015] Furthermore, the cutting edge of the cutting blade is arranged vertically upward, and the cutting blade includes a horizontal rod connected to the inner wall of the positioning tube, and the end of the horizontal rod is equipped with an arc-shaped blade coaxially arranged with the storage tube, the cutting edge of the arc-shaped blade is arranged upward, and the arc-shaped blade is arranged directly below the feed channel.

[0016] Furthermore, the inner wall of the bottom end of the positioning tube is constructed with an annular groove for accommodating the packaging mechanism, and the packaging mechanism includes a fixing tube coaxially arranged with the positioning tube and embedded in the annular groove, and a receiving ring is coaxially installed on the outer wall of the bottom end of the fixing tube, and the receiving ring is made of iron. A compression ring is threadedly installed on the outer wall of the fixing tube, and the compression ring is located above the receiving ring. The compression ring and the receiving ring serve as a packaging bag clamping part, and the part of the fixing tube located in the annular groove is made of iron material, and a magnet block is embedded on the inner wall of the annular groove.

[0017] Furthermore, a plurality of the pressing and limiting mechanisms are provided in the storage tube along the extension direction of the axis thereof.

[0018] The present invention relates to a vertical winding and packaging device for waterproof coiled materials, which has the following beneficial effects: The waterproofing coil can be packaged vertically, thus preventing uneven winding of the coil after winding, caused by different movement trends of the coil on either side of the winding shaft due to its own weight. Combined with a compression and limiting mechanism within the storage barrel, this prevents the problem of the waterproofing coil being subjected to different forces on either side of the rotating shaft due to its own weight. Thus, the compression and limiting mechanism, which applies horizontal force to the waterproofing coil, ensures that the waterproofing coil is subjected to the same compressive force in all directions toward the axis of the rotating shaft during vertical winding, thereby ensuring uniform winding of the waterproofing coil. Furthermore, combined with a pushing mechanism and a packaging and cutting mechanism, the compression and limiting mechanism also serves to squeeze and shape the coil during its ejection. In conjunction with the cutting blade of the packaging and cutting mechanism, when the pushing mechanism pushes the wound coil downward, the coil, once cut, can be removed from the rotating shaft and packaged by the packaging mechanism. This allows for more continuous winding and packaging by eliminating the need for bundling operations, thereby increasing production efficiency.

[0019] Furthermore, in order to achieve the second purpose of this application, this application adopts the following technical means: A method for vertically winding a waterproof coiled material, using the aforementioned vertical winding and packaging device for the waterproof coiled material, comprises the following steps: The end of the waterproof roll to be packaged is kept in a vertical state and passed through the feeding channel, and then the end of the roll is embedded in the embedding groove, and then the rotating shaft is rotated by the rotating motor to reel the roll; During the reeling process, the outer wall of the waterproof roll wound on the rotating shaft always contacts the ball structure of the abutment end of the pressing and limiting mechanism. Under the action of the electromagnet, the push rod as the abutment mechanism always presses the outer wall of the roll; As the winding progresses, the thickness of the coil on the rotating shaft gradually increases, forcing the push rod as the abutment mechanism to continuously approach the electromagnet. Under the state of uniform winding, the magnetic strength of the electromagnet is set to periodically decay. At the beginning of the winding operation, the magnetic force of the electromagnet is at its maximum. During the winding process, the magnetic force of the electromagnet gradually decreases. After it decreases to the minimum, the winding ends and the magnetic force of the electromagnet returns to its maximum. After the winding is completed, the pushing mechanism is started to push the waterproofing roll wrapped on the rotating shaft from top to bottom, so that it falls off from the bottom end of the rotating shaft. During the pushing and falling process, the roll near the feeding channel is deformed and contacts the edge of the cutting blade. The cutting blade cuts the roll until the rolled roll is completely out of the bottom end of the rotating shaft, and the cutting is completed. The cut roll passes through the positioning tube and falls into the packaging mechanism under the action of its own weight, and contacts the bottom end of the packaging bag clamped between the compression ring and the receiving ring, which increases the weight of the packaging bag and forces the fixing tube to separate from the magnetic attraction part of the magnet block, allowing the fixing tube and the packaging bag to fall off from the annular groove together, completing the winding and packaging of the waterproof roll.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0034] Please refer to Figures 1 to 7 As shown, a vertical winding and packaging device for waterproof coiled material includes: A vertically arranged storage cylinder 1 with two through ends, wherein a rotating shaft 2 is coaxially constructed inside the storage cylinder 1, one end of the rotating shaft 2 extends from the top end of the storage cylinder 1 and is connected to the rotating end of the rotating motor, and a feeding channel 3 is constructed on the side wall of the storage cylinder 1 parallel to its axis; A clamping and limiting mechanism is provided in the storage tube 1 and includes a clamping rod 4 arranged around the axis of the storage tube 1. The clamping rod 4 is configured with an abutment mechanism that moves linearly along the axis of the clamping rod 4 at one end facing the rotating shaft 2. A damping mechanism that applies thrust to the abutment mechanism is provided in the clamping rod 4. The end of the abutment mechanism is arranged to abut against the material wound around the rotating shaft 2. A pushing mechanism 5 is coaxially arranged on the top side of the storage tube 1 and is configured with a through channel 6 for the rotation shaft 2 to pass through. The side of the pushing mechanism 5 facing away from the storage tube 1 is connected to the telescopic motor via a connecting rod 7; The packaging and dividing mechanism is coaxially arranged at the bottom end of the storage tube 1, and includes a positioning tube 8 coaxially fixedly connected to the bottom end of the storage tube 1. A cutting blade 9 is installed on the inner wall of the positioning tube 8, and a packaging mechanism is coaxially disassembled and installed at the bottom end of the positioning tube 8.

[0035] In this way, the waterproofing coil can be packaged vertically, thus preventing the waterproofing coil from moving differently on either side of the winding shaft 2 due to its own weight, which could result in uneven winding after the coil is wound. Furthermore, the combination of a compression and limiting mechanism within the storage tub prevents the waterproofing coil from being subjected to different forces on either side of the winding shaft 2 due to its own weight. The compression and limiting mechanism, which applies horizontal force to the waterproofing coil, ensures that the waterproofing coil is subjected to the same compressive force in all directions, directed toward the axis of the winding shaft 2, during the vertical winding process, ensuring uniform winding. Furthermore, in combination with the pushing mechanism 5 and the packaging and cutting mechanism, the compression and limiting mechanism also compresses and shapes the coil as it is pushed out. In conjunction with the cutting blade 9 of the packaging and cutting mechanism, as the pushing mechanism 5 pushes the wound coil downward, the coil, once cut, can be removed from the winding shaft 2 and packaged by the packaging mechanism. This allows for more continuous winding and packaging by eliminating the need for bundling operations, thereby increasing production efficiency.

[0036] Furthermore, in order to enable the coil to be better combined with the rotating shaft 2 at the initial stage of winding, the side wall of the rotating shaft 2 is provided with an embedding groove 10 extending along its axis, and the bottom end of the embedding groove 10 is set through the bottom end of the rotating shaft 2, and the embedding groove 10 is aligned with the feed channel 3.

[0037] In this way, at the initial stage of winding, the head end of the waterproof roll moves toward the embedding groove 10 under the action of the external feeding equipment. When the end of the waterproof roll is loaded into the embedding groove 10, the rotating shaft 2 starts to rotate. By utilizing the interaction between the embedding groove 10 and the waterproof roll, the waterproof roll can fit tightly with the rotating shaft 2 at the initial stage of winding.

[0038] Furthermore, pressure rollers 11 are installed at both horizontal ends of the feed channel 3 , and the material to be wound passes between the two pressure rollers 11 .

[0039] Furthermore, the clamping rod 4 is installed on the inner wall of the storage tube 1, and a sliding cavity 12 is constructed in the clamping rod 4. A push rod 13 serving as the abutment mechanism is slidably arranged in the sliding cavity 12. One end of the push rod 13 is slidably arranged in the sliding cavity 12, and the other end of the push rod 13 extends out of the sliding cavity 12 and is rotatably installed with a ball 14.

[0040] In this way, the ball 14 rotatably mounted at the end of the push rod 13 contacts the outer wall of the waterproof coiled material during the winding process. The rotation of the ball 14 not only allows the ball 14 to match the movement of the outer wall of the waterproof coiled material during the winding process, thereby preventing severe wear of the outer wall of the waterproof coiled material caused by the push rod 13 abutting against the outer wall of the waterproof coiled material, but also allows the ball 14 to match the movement of the waterproof coiled material along the axis of the rotating shaft 2 during the vertical pushing process after the end of the push rod 13 has abutted against the waterproof coiled material, thus preventing severe wear between the outer wall of the waterproof coiled material and the push rod 13 during the unloading process.

[0041] Furthermore, the damping mechanism includes an electromagnet 15 installed in the sliding cavity 12, and a permanent magnet 16 installed at one end of the push rod 13 located in the sliding cavity 12, and the magnetism of the opposite surfaces of the electromagnet 15 and the permanent magnet 16 are set to be the same.

[0042] Therefore, the damping mechanism for applying thrust to the push rod 13 is composed of an electromagnet 15 and a permanent magnet. After the electromagnet 15 is energized, a repulsive force can be generated between it and the permanent magnet 16, and the repulsive force is used to push the push rod 13 out of the sliding cavity 12, so that the ball 14 located at the end of the push rod 13 can abut against the outer wall of the coil.

[0043] At the same time, the electromagnet 15 can also communicate with the PLC controller. When the rotating shaft 2 is reeling at a constant speed and the pushing structure is moving at a constant speed, the time required to complete one reeling and discharging operation is fixed. Therefore, this fixed time is set as the threshold for the change in the magnetic force of the electromagnet 15. Within this set time range, the magnetic force of the electromagnet 15 gradually decreases at a constant speed. This ensures that when the push rod 13 continuously moves toward the electromagnet 15, the distance between the push rod 13 and the electromagnet 15 is prevented from decreasing, thereby preventing the repulsive force from gradually increasing. In this way, the gradually decreasing magnetic force of the electromagnet 15 can, on the one hand, balance the compressive force applied by the push rod 13 to the waterproof coiled material. On the other hand, it can effectively prevent the push rod 13 from being pushed out quickly and vigorously by the electromagnet 15 after the waterproof coiled material is pushed out and suddenly releases its contact with the waterproof coiled material, thereby easily pushing the push rod 13 out of the clamping rod 4 and damaging the clamping limit mechanism.

[0044] Furthermore, the pressing rod 4 is constructed with a ventilation channel 17 that passes through its side wall and communicates with the sliding cavity 12 .

[0045] In this way, the air pressure in the sliding cavity 12 is kept consistent with that in the outside through the vent channel 17 .

[0046] Furthermore, the cutting edge of the cutting blade 9 is set vertically upward, and the cutting blade 9 includes a horizontal rod 18 connected to the inner wall of the positioning tube 8, and the end of the horizontal rod 18 is installed with an arc-shaped blade 19 coaxially arranged with the storage tube 1, and the cutting edge of the arc-shaped blade 19 is set upward, and the arc-shaped blade 19 is arranged directly below the feed channel 3.

[0047] Furthermore, the inner wall of the bottom end of the positioning tube 8 is constructed with an annular groove 20 for accommodating the packaging mechanism. The packaging mechanism includes a fixing tube 21 coaxially arranged with the positioning tube 8 and embedded in the annular groove 20. The outer wall of the bottom end of the fixing tube 21 is coaxially installed with a receiving ring 22, and the receiving ring 22 is made of iron. The outer wall of the fixing tube 21 is threadedly installed with a compression ring 23, and the compression ring 23 is located above the receiving ring 22. The compression ring 23 and the receiving ring 22 serve as a packaging bag clamping part. The part of the fixing tube 21 located in the annular groove 20 is made of iron material, and the inner wall of the annular groove 20 is embedded with a magnet block 24.

[0048] Furthermore, a plurality of the aforementioned pressing and limiting mechanisms are provided in the storage tube 1 along the extending direction of its axis.

[0049] In addition, when the waterproof coiled material is vertically rolled and packaged using the aforementioned waterproof coiled material vertical rolling and packaging device, the following steps are performed: The end of the waterproof roll to be packaged is kept in a vertical state and passes through the feed channel 3, and then the end of the roll is embedded in the embedding groove 10, and then the rotating shaft 2 is rotated by the rotating motor to reel the roll; During the reeling process, the outer wall of the waterproofing coiled material wound on the rotating shaft 2 always abuts against the ball 14 of the abutting end structure of the pressing and limiting mechanism. Under the action of the electromagnet 15, the push rod 13 as the abutting mechanism always presses the outer wall of the coiled material. As the winding progresses, the thickness of the coil on the rotating shaft 2 gradually increases, forcing the push rod 13, which serves as the abutment mechanism, to continuously approach the electromagnet 15. Under the state of uniform winding, the magnetic strength of the electromagnet 15 is set to periodically decay. At the beginning of the winding operation, the magnetic force of the electromagnet 15 is at its maximum. During the winding process, the magnetic force of the electromagnet 15 gradually decreases. After it decreases to the minimum, the winding is completed and the magnetic force of the electromagnet 15 returns to its maximum. After the winding is completed, the pushing mechanism 5 is started to push the waterproof coiled material wound on the rotating shaft 2 from top to bottom, so that it falls off from the bottom end of the rotating shaft 2. During the pushing and falling process, the coiled material near the feeding channel 3 is deformed and contacts the edge of the cutting blade 9. The cutting blade 9 cuts the coiled material until the wound coiled material completely falls off from the bottom end of the rotating shaft 2. The cutting is completed. The cut coil passes through the positioning tube 8 and falls into the packaging mechanism under the action of its own weight, and contacts the bottom end of the packaging bag clamped between the compression ring 23 and the receiving ring 22, so that the weight of the packaging bag increases, forcing the magnetic attraction part of the fixing tube 21 and the magnet block 24 to separate, allowing the fixing tube 21 and the packaging bag to fall off from the annular groove 20 together, completing the winding and packaging of the waterproof coil.

[0050] Moreover, for the clamping state of the packaging bag, the aforementioned thread for installing the compression ring 23 extends to the top surface of the receiving ring 22, so that when the compression ring 23 moves to the lowest end along the thread, it can abut against the receiving ring 22, thereby achieving clamping of the packaging bag.

[0051] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
