Description

Technical Field

[0001] This utility model relates to the field of roll packaging technology, specifically to a packaging machine for processing waterproof rolls. Background Technology

[0002] Waterproof membranes are commonly used on rooftops as a sealing and waterproofing material to prevent water from entering the building. The manufacturing process of waterproof membranes varies depending on the type. Generally, to extend the service life of waterproof membranes, they are often produced using a two-layer pressing method. After manufacturing, to facilitate storage and transportation, a protective film is wrapped around the outside of the waterproof membrane to prevent scratches or other damage to its outer surface during transport.

[0003] A search revealed that patent CN202020035069.9 discloses a waterproof roll packaging device. While this device continuously wraps the outer side of the waterproof roll with packaging film under the rotation of roller 37 and conveyor wheel 49 until packaging is complete, and then the lifting cylinder 30 moves roller 37 downwards, and the push wheel 22 moves the packaged waterproof roll out of the device, the wrapping and feeding processes are performed in steps. This means that the next step cannot begin until the previous one is completed. This step-by-step operation mode may prolong the overall packaging process, thus reducing production efficiency. Due to this inefficiency, packaging the same quantity of waterproof rolls may take longer, potentially increasing labor costs, equipment operating costs, and energy costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a packaging machine for processing waterproof roll materials, which solves the problems mentioned in the background art.

[0005] The solution of this utility model to the above-mentioned technical problems is as follows:

[0006] A packaging machine for processing waterproof roll materials includes a displacement component, on which a support component is mounted, and a roll material is dragged and placed on the displacement component via the support component.

[0007] The displacement assembly has a base plate, one end of which is movably supported by a bracket and a packaging film. A fixed seat is installed on the upper surface of the base plate, and a second motor is installed on the fixed seat. A transmission rod is installed at the output end of the second motor. The transmission rod is supported on the base plate by a bearing seat. Two support assemblies are movably installed on the displacement assembly via two transmission rods.

[0008] The support assembly is provided with a tray, on which a rotating shaft is rotatably mounted. A spiral roller is provided on the rotating shaft. A first motor is installed on one side of the rotating shaft on the support assembly. The rotating shaft and the first motor are connected by a synchronous belt drive. The roll material is conveyed forward while rotating by interacting with the spiral roller.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the transmission rod consists of a first lead screw and a second lead screw, and the threads of the first lead screw and the second lead screw are opposite in direction. The first lead screw and the second lead screw drive the two support plates to move in opposite directions.

[0011] The beneficial effects of adopting the above-mentioned further solutions are:

[0012] This design fully utilizes the thread characteristics of the lead screw, achieving the opposite or reverse movement of the two pallets by changing the thread direction. This design not only boasts a compact structure, reducing the equipment's footprint, but also makes the entire transmission system simpler, clearer, and easier to maintain and repair.

[0013] Furthermore, the spiral rollers of the two support components on the displacement assembly rotate in the same direction.

[0014] The beneficial effects of adopting the above-mentioned further solutions are:

[0015] When the spiral rollers of the two support components rotate in the same direction, their pushing force on the roll material is consistent. This consistency ensures that the roll material maintains a stable motion during transport, preventing instability such as deviation or jumping. During packaging, the roll material needs to be tightly wound with the packaging film. When the spiral rollers rotate in the same direction, they can jointly apply a stable thrust to the roll material, allowing it to be evenly stretched and wound around the packaging film while being transported forward. This design improves the wrapping effect of the packaging film, ensuring the roll material is tightly wrapped within it, thereby enhancing the strength and aesthetics of the packaging.

[0016] Furthermore, the roll material is automatically pulled and wrapped with packaging film while being rotated and conveyed forward.

[0017] The beneficial effects of adopting the above-mentioned further solutions are:

[0018] This design allows the roll material to be automatically stretched and wrapped with packaging film during forward conveying, enabling rapid packaging. Compared to traditional manual packaging or packaging methods requiring additional equipment, this automated packaging method significantly improves packaging efficiency, shortens the packaging cycle, and reduces labor costs. Automated stretch wrapping ensures a tight fit between the packaging film and the roll material, avoiding problems such as loosening or detachment that can occur in traditional packaging methods. This tight fit not only improves packaging strength but also effectively prevents contamination of the roll material by external factors such as dust and moisture, thus ensuring the quality and performance of the roll material. Automated stretch wrapping can precisely package the roll material according to its size and shape, avoiding the waste of packaging materials that can occur in traditional packaging methods. This precise packaging not only saves packaging materials and reduces packaging costs but also reduces environmental impact, aligning with the concept of sustainable development.

[0019] Furthermore, the rotating shaft is provided with two spiral rollers, and the packaging film is located on the center line of the spiral rollers at both ends.

[0020] The beneficial effects of adopting the above-mentioned further solutions are:

[0021] The design of two-segment spiral idlers provides more efficient support and transport of the roll material. Because they are located on the rotating shaft and positioned opposite each other, they work together to generate a stable clamping force on the roll material, ensuring its stability during transport. This design is particularly suitable for longer or heavier roll materials, effectively preventing shifting or detachment during transport. Positioning the packaging film along the centerline of the two spiral idlers ensures that the film is evenly wound onto the roll material. As the roll material is transported, the rotation of the spiral idlers propels the roll forward, simultaneously pulling the packaging film for winding. Because the packaging film is positioned along the centerline, it is pulled simultaneously from both sides of the roll material, achieving a uniform winding effect. The two-segment spiral idler design not only improves the stability of roll material transport but also enhances the strength and aesthetics of the packaging. Due to the spiral shape of the idlers, they generate a forward thrust on the roll material, which helps to tightly adhere the packaging film to the roll material. Simultaneously, because the packaging film is evenly wound onto the roll material, a neat and aesthetically pleasing packaging effect is achieved.

[0022] Furthermore, the bottom end of the pallet is provided with a nut seat, and the pallet moves linearly on the displacement assembly through the engagement of the nut seat and the transmission rod.

[0023] The beneficial effects of adopting the above-mentioned further solutions are:

[0024] This design allows for a more compact connection between the pallet and the drive rod. The engagement of the nut seat with the drive rod enables linear movement of the pallet on the displacement assembly. This structure not only reduces the equipment's footprint but also makes the entire transmission system simpler, easier to maintain, and more straightforward. The engagement between the nut seat and the drive rod provides a high-precision transmission method, enabling precise movement of the pallet on the displacement assembly. Due to the tight contact of the meshing surfaces and the rigid support of the drive rod, this design offers high stability and reliability, ensuring the accuracy and precision of the pallet during movement. This design allows for flexible adjustment of the pallet according to different production needs. By changing the speed or direction of the drive rod, or adjusting the position of the nut seat, precise control of the pallet's movement speed, distance, and direction can be achieved. This flexibility allows the equipment to adapt to the packaging needs of roll materials of different specifications and materials.

[0025] This utility model provides a packaging machine for processing waterproof roll materials. It has the following beneficial effects:

[0026] Automatic conveying of roll materials and automatic stretching and wrapping of packaging film are achieved through motor drives (such as a second motor driving a transmission rod and a spiral roller on a first motor driving a rotating shaft), greatly reducing manual operation and improving production efficiency.

[0027] The ingenious design of the displacement and support components makes the entire packaging machine compact and space-saving. Meanwhile, the drive rod consists of a first lead screw and a second lead screw with opposite thread directions. This design allows the two pallets to move in opposite directions, accommodating rolls of different sizes and increasing the equipment's flexibility.

[0028] Due to the rotation of the spiral idler roller, the roll material rotates and is conveyed forward while interacting with the spiral idler roller. This conveying method allows the roll material to be wound evenly and tightly onto the packaging film, ensuring the packaging effect. Attached Figure Description

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.

[0038] Please see Figures 1 to 4 As shown, the embodiments provided by this utility model are as follows:

[0039] Example 1

[0040] A packaging machine for processing waterproof roll material includes a displacement component 1, a support component 2 mounted on the displacement component 1, a roll material 3 being dragged and placed on the displacement component 1 via the support component 2, a base plate 102 provided on the displacement component 1, a packaging film 103 being movably supported at one end of the base plate 102 via a bracket, a fixed seat 105 mounted on the upper surface of the base plate 102, a second motor 108 mounted on the fixed seat 105, a transmission rod 104 mounted on the output end of the second motor 108, the transmission rod 104 being supported on the base plate 102 via a bearing seat 101, the transmission rod 104 being composed of a first lead screw 106 and a second lead screw 107, with the threads of the first lead screw 106 and the second lead screw 107 having opposite directions, driving two pallets 203 to move towards or in opposite directions via the first lead screw 106 and the second lead screw 107, this design fully utilizes the thread characteristics of the lead screw, achieving the opposite or in opposite directions movement of the two pallets 203 by changing the thread direction. This design not only boasts a compact structure, reducing the equipment's footprint, but also makes the entire transmission system simpler, clearer, and easier to maintain and repair. This design fully utilizes the thread characteristics of the lead screw, achieving the opposite or reverse movement of the two support plates 203 by changing the thread direction. The displacement assembly 1 has two support assemblies 2 movably mounted on it via two transmission rods 104.

[0041] Example 2

[0042] To accommodate different sizes of rolls, for example, such as Figures 1 to 4As shown, the present invention also includes: a support assembly 2 with a support plate 203, and a nut seat 205 at the bottom end of the support plate 203. The support plate 203 engages with the transmission rod 104 through the nut seat 205 to move linearly on the displacement assembly 1. This design makes the connection between the support plate 203 and the transmission rod 104 more compact. Through the engagement of the nut seat 205 and the transmission rod 104, the linear movement of the support plate 203 on the displacement assembly 1 is achieved. This structure not only reduces the footprint of the equipment but also makes the entire transmission system simpler, clearer, and easier to maintain and repair. The engagement between the nut seat 205 and the transmission rod 104 is a high-precision transmission method, enabling precise movement of the support plate 203 on the displacement assembly 1. Due to the close contact of the meshing surfaces and the rigid support of the transmission rod 104, this design has high stability and reliability, ensuring the accuracy and precision of the support plate 203 during movement. This design allows the support plate 203 to be flexibly adjusted according to different production needs. By changing the rotation speed and direction of the transmission rod 104 or adjusting the position of the nut seat 205, precise control can be achieved over the moving speed, moving distance, and moving direction of the pallet 203. This flexibility allows the equipment to adapt to the packaging needs of rolls 3 of different specifications and materials. A rotating shaft 201 is rotatably mounted on the pallet 203. The spiral rollers 204 of the two support components 2 on the displacement component 1 rotate in the same direction. When the spiral rollers 204 of the two support components 2 rotate in the same direction, their pushing action on the roll 3 is consistent. This consistency ensures that the roll 3 maintains a stable motion state during transportation, avoiding instability such as deviation or jumping during transportation. During the packaging process, the roll 3 needs to be tightly wrapped with the packaging film 103. When the spiral rollers 204 rotate in the same direction, they can jointly apply a stable thrust to the roll 3, so that the roll 3 can be evenly stretched and wrapped around the packaging film 103 while being transported forward. This design improves the wrapping effect of the packaging film 103, ensuring the roll 3 is tightly wrapped within it, thus enhancing the packaging's strength and aesthetics. The rotating shaft 201 is equipped with two spiral rollers 204, with the packaging film 103 positioned on the center line of both spiral rollers 204. This two-segment spiral roller design effectively supports and transports the roll 3. Because they are located on the rotating shaft 201 and arranged opposite each other, they collectively generate a stable clamping force on the roll 3, ensuring its stability during transport. This design is particularly suitable for longer or heavier rolls 3, effectively preventing them from shifting or falling off during transport. Positioning the packaging film 103 on the center line of the two spiral rollers 204 ensures it is evenly wrapped around the roll 3. As the roll 3 is transported, the rotation of the spiral rollers 204 propels the roll forward, simultaneously pulling and winding the packaging film 103.Because the packaging film 103 is located at the center line, it can be stretched simultaneously from both sides of the roll 3, thus achieving a uniform winding effect. The design of the two-segment spiral rollers 204 not only improves the stability of the roll 3 conveying but also enhances the strength and aesthetics of the packaging. Due to the spiral shape of the spiral rollers 204, they can generate a forward thrust on the roll 3, which helps to tightly adhere the packaging film 103 to the roll 3. At the same time, since the packaging film 103 is evenly wound on the roll 3, a neat and aesthetically pleasing packaging effect can be formed. A first motor 202 is installed on one side of the rotating shaft 201 on the support assembly 2. The rotating shaft 201 and the first motor 202 are connected by a synchronous belt drive. The roll 3 is conveyed forward while rotating in interaction with the spiral rollers 204. As the roll 3 rotates and is conveyed forward, it automatically pulls and wraps the packaging film 103. This design allows the roll 3 to automatically pull and wrap the packaging film 103 during forward conveying, thus achieving rapid packaging of the roll 3. Compared to traditional manual packaging or packaging methods requiring additional equipment, this automated packaging method significantly improves packaging efficiency, shortens the packaging cycle, and reduces labor costs. The automated stretch wrapping film 103 ensures a tight fit between the film 103 and the roll material 3, avoiding problems such as loosening or detachment that can occur in traditional packaging methods. This tight fit not only improves the packaging's strength but also effectively prevents contamination of the roll material 3 by external factors such as dust and moisture, thus ensuring the quality and performance of the roll material 3. The automated stretch wrapping film 103 can precisely package the roll material 3 according to its size and shape, avoiding the waste of packaging materials that can occur in traditional packaging methods. This precise packaging not only saves packaging materials and reduces packaging costs but also reduces environmental impact, aligning with the concept of sustainable development.

[0043] Working principle:

[0044] The displacement assembly 1 is the foundation of the entire packaging machine, providing a platform for conveying and positioning the roll 3. A base plate 102 is mounted on the displacement assembly 1, and a packaging film 103 is movably supported at one end of the base plate 102 via a bracket, providing the necessary material for packaging the roll 3.

[0045] A roll of material 3 is dragged onto the displacement assembly 1 via a support assembly 2. The support assembly 2 is equipped with a support plate 203, which engages with a transmission rod 104 via a nut seat 205, allowing it to move linearly on the displacement assembly 1. This design enables the support assembly 2 to be adjusted according to the width of the roll of material 3, ensuring the stability of the roll of material 3 during transport.

[0046] A fixed base 105 is mounted on the upper surface of the base plate 102, and a second motor 108 is mounted on the fixed base 105. A transmission rod 104 is mounted on the output end of the second motor 108. The transmission rod 104 consists of a first lead screw 106 and a second lead screw 107, with opposite thread directions. When the second motor 108 starts, it drives the transmission rod 104 to rotate. Since the threads of the first lead screw 106 and the second lead screw 107 are opposite, the two support plates 203 will move towards or in opposite directions, thereby adjusting the distance between the support components 2.

[0047] A rotating shaft 201 is rotatably mounted on the support assembly 2, and a spiral roller 204 is mounted on the rotating shaft 201. The spiral roller 204 is designed so that when the roll material 3 is placed on it, it can rotate and be conveyed forward as the spiral roller 204 rotates. At the same time, due to the spiral shape of the spiral roller 204, it can also generate a certain thrust on the roll material 3, helping it move forward. When the spiral roller 204 rotates under the drive of the motor, its spiral-shaped surface will come into contact with the roll material 3. Due to the continuity of the spiral, the roll material 3 will be subjected to a force along the tangential direction of the spiral at the contact point. This force can be decomposed into two components: one is a normal force perpendicular to the direction of movement of the roll material 3, and the other is a tangential force parallel to the direction of movement of the roll material 3. The normal force is the vertical pressure of the spiral roller 204 on the roll material 3, which causes friction between the roll material 3 and the spiral roller 204. This friction is the basis for the roll material 3 to rotate with the spiral roller 204. The tangential force is the force exerted by the helical idler roller 204 on the coil 3 along the tangential direction of the helix. Due to the shape of the helix, this tangential force continuously changes direction and generates a continuous thrust along the direction of movement of the coil 3. This thrust is the reason why the helical idler roller 204 can push the coil 3 forward.

[0048] A first motor 202 is mounted on one side of the rotating shaft 201 on the support assembly 2, and the rotating shaft 201 and the first motor 202 are connected by a synchronous belt drive. When the first motor 202 starts, it drives the rotating shaft 201 and the spiral roller 204 to rotate.

[0049] The packaging film 103 is located on the center line of the spiral rollers 204 at both ends. When the roll 3 is conveyed forward by the rotation of the spiral rollers 204, it will automatically be pulled and wound onto the packaging film 103. Due to the continuous rotation of the spiral rollers 204 and the forward conveying of the roll 3, the packaging film 103 will be evenly wound onto the roll 3.

[0050] As the roll 3 rotates and is conveyed forward on the spiral roller 204, and the packaging film 103 is continuously wound, the entire packaging process is gradually completed. When the roll 3 reaches the predetermined packaging length, the operation of the first motor 202 and the second motor 108 can be stopped.

[0051] After packaging is complete, the packaged roll 3 can be removed from the equipment using other mechanical devices. At this point, the displacement component 1 and the support component 2 can be adjusted back to their initial positions, ready for the next round of packaging operations.
