Description

Technical Field

[0001] This utility model relates to the field of packaging technology, specifically to a roll-up machine and its roll-up drive mechanism. Background Technology

[0002] Mattresses need to be packaged before leaving the factory. In order to further reduce the size of the mattress and facilitate transportation, sometimes the mattress is rolled up into a long cylindrical roll. The packaged mattress not only reduces the size and facilitates transportation, but the protective layer of the packaging can also reduce the damage to the mattress during transportation.

[0003] The rolling and wrapping of mattresses is generally done using a mattress rolling and wrapping machine. During operation, the mattress is first placed into the mattress conveyor channel of the machine, and then fed into the rolling and wrapping space for packaging. As the mattress rolls, the packaging film also rolls up, thus wrapping the mattress after rolling and initially restraining it to prevent it from bursting open. While existing mattress rolling and wrapping machines can adjust the size of the rolling and wrapping space, the adjustment range is not flexible enough to roll the mattress into a small-diameter cylindrical roll.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0034] Please see Figures 1 to 3 This utility model provides a wrapping machine wrapping drive mechanism, including: a wrapping conveying assembly 10, a first side conveying assembly 20, a lifting drive assembly 30, an upper wrapping assembly 40, and a translation drive assembly 50.

[0035] The first side conveying assembly 20 is provided at the conveying end of the roll conveying assembly 10, and the first side conveying assembly 20 has an upwardly extending first side roll driving part 21 on the side facing the roll conveying assembly 10.

[0036] The lifting drive assembly 30 is driven to connect with the first side conveying assembly 20 and is used to drive the first side conveying assembly 20 to lift.

[0037] The upper package assembly 40 is disposed above the package conveying assembly 10. The upper package assembly 40 includes a mounting frame 41, an upper conveying assembly 42, and a second side conveying assembly 43. The upper conveying assembly 42 and the second side conveying assembly 43 are on the mounting frame 41. An upper package drive part 421 is formed at the bottom of the upper conveying assembly 42. A second side package drive part 431 is formed on the side of the second side conveying assembly 43 facing the first side conveying assembly 20. The first side package drive part 21, the second side package drive part 431, the top of the package conveying assembly 10, and the upper package drive part 421 together form the package space 11.

[0038] The translation drive assembly 50 is driven to connect with the mounting frame 41. Under the drive of the translation drive assembly 50, the mounting frame 41 moves toward the first side conveyor assembly 20 and the roll pack conveyor assembly 10 and moves away from the first side conveyor assembly 20 and the roll pack conveyor assembly 10. When the mounting frame 41 moves toward the first side conveyor assembly 20 and the upper roll pack assembly 40 under the drive of the translation drive assembly 50, the upper roll pack drive part 421 approaches the top of the roll pack conveyor assembly 10, and the second side roll pack drive part 431 approaches the first side roll pack drive part 21. When the mounting frame 41 moves away from the first side conveyor assembly 20 and the upper roll pack assembly 40 under the drive of the translation drive assembly 50, the upper roll pack drive part 421 moves away from the top of the roll pack conveyor assembly 10, and the second side roll pack drive part 431 moves away from the first side roll pack drive part 21.

[0039] The working principle of the wrapping drive mechanism of a wrapping machine according to an embodiment of the present invention is explained below:

[0040] The mattress enters the roll-up conveyor assembly 10, which transports it towards the first side conveyor assembly 20. The first side conveyor assembly 20 rises under the drive of the lifting drive assembly 30, causing the first side roll-up drive part 21 to be at a suitable height above the roll-up conveyor assembly 10 to block the end of the mattress. Meanwhile, the upper roll-up assembly 40 moves towards the roll-up conveyor assembly 10 and the first side conveyor assembly 20 under the drive of the translation drive assembly 50. This causes the upper roll-up drive part 421 of the upper roll-up assembly 40 to approach the roll-up conveyor assembly 10, and the second side roll-up drive part 431 to approach the first side roll-up drive part 21. This forms a roll-up space 11 between the first side roll-up drive part 21, the second side roll-up drive part 431, the upper roll-up drive part 421, and the roll-up conveyor assembly 10. The end of the mattress... Following the first side roll-up drive unit 21, the mattress is conveyed upward by the first side roll-up drive unit 21, causing the end of the mattress to move toward the upper roll-up drive unit 421. Subsequently, the end of the mattress abuts against the upper roll-up drive unit 421 and is driven by the upper roll-up drive unit 421 to move toward the second side roll-up drive unit 431. When the end of the mattress abuts against the second side roll-up drive unit 431, the end of the mattress is driven by the second side roll-up drive unit 431 toward the roll-up conveying assembly 10, thereby guiding the end of the mattress to move downward. Subsequently, the end of the mattress abuts against the top of the mattress itself. At this time, the mattress is roughly guided to bend into a circle. Then, the mattress is continuously driven to move by the first side roll-up drive unit 21, the second side roll-up drive unit 431, the upper roll-up drive unit 421, and the roll-up conveying assembly 10 to achieve roll-up within the roll-up space 11. It should be noted that during the rolling process, the packaging film conveying mechanism 80 attaches the packaging film to the surface of the mattress, so that the mattress rolls up along with the packaging film. Alternatively, the packaging film can be conveyed to the mattress surface after the mattress is rolled up, and then the mattress continues to rotate, causing the packaging film to wrap around the mattress several times. The packaging film is then welded together to secure the different layers, thus preventing the mattress from bursting open. Cutting the packaging film completes the mattress rolling operation. After the mattress is rolled up, the first side rolling assembly descends under the drive of the lifting drive assembly 30, and then the rolling conveying assembly 10 transports the mattress, rolled into a long cylindrical roll, away.

[0041] The diameter of the cylindrical roll after the mattress is rolled up depends on the height difference between the upper rolling drive unit 421 and the rolling conveyor assembly 10, as well as the distance between the first side rolling drive unit 21 and the second side rolling drive unit 431. The height of the rolling conveyor assembly 10 remains constant; therefore, the height difference between the upper rolling drive unit 421 and the rolling conveyor assembly 10 depends on the position of the upper rolling drive unit 421. The first side rolling drive unit 21 can only move up and down; therefore, the distance between the first side rolling drive unit 21 and the second side rolling drive unit 431 depends on the position of the second side rolling drive unit 431. Therefore, the height difference between the upper rolling drive unit 421 and the rolling conveyor assembly 10, as well as the distance between the first side rolling drive unit 21 and the second side rolling drive unit 431, can be synchronously adjusted by moving the mounting bracket 41. The height of the first side rolling drive unit 21 is then adaptively adjusted according to the height of the upper rolling drive unit 421. (See also...) Figure 4 When it is necessary to roll the mattress into a long, cylindrical roll with a small diameter, it is only necessary to lower the upper rolling drive unit 421 to a sufficiently low height and bring the second side rolling drive unit 431 close enough to the first side rolling drive unit 21, while the first side rolling drive unit 21 is lowered adaptively. See also... Figure 5 When it is necessary to roll the mattress into a long cylindrical roll with a large diameter, it is only necessary to raise the upper rolling drive unit 421 to a sufficient height and ensure that the second side rolling drive unit 431 is sufficiently far away from the first side rolling drive unit 21, while the first side rolling drive unit 21 rises adaptively. Therefore, the diameter of the cylindrical roll that the rolling space 11 accommodates depends on the positions of the second side rolling drive unit 431 and the upper rolling drive unit 421. The position of the first side rolling drive unit 21 is only adjusted adaptively and does not affect the diameter of the cylindrical roll that the rolling space 11 accommodates. Since both the second side rolling drive unit 431 and the upper rolling drive unit 421 are mounted on the mounting bracket 41 and move synchronously, the size adjustment of the rolling space 11 is relatively convenient and intuitive.

[0042] It should be noted that the diameter of the cylindrical roll after the mattress is rolled up depends on the thickness of the mattress and the length of the mattress in the conveying direction of the roll conveying assembly 10.

[0043] It should be noted that the conveying end of the roll conveyor assembly 10 refers to the position where the mattress detaches from the roll conveyor assembly 10 under its conveying action.

[0044] The specific structure of the translation drive assembly 50 can be selected according to actual needs. For example, the translation drive assembly 50 can be a lead screw drive assembly, a rotary motor translation drive assembly 50, a belt translation drive assembly 50, a cylinder translation drive assembly 50, or a linear motor translation drive assembly 50, etc., and is not limited to this example.

[0045] In some alternative embodiments, the upper conveying assembly 42 is an upper belt conveyor assembly, and the upper roll drive unit 421 is formed on the belt conveying surface at the bottom of the upper belt conveyor assembly. The friction between the belt conveying surface at the bottom of the upper belt conveyor assembly and the mattress drives the mattress to move, thereby realizing the conveying of the mattress. The structure of the upper belt conveyor assembly is well known to those skilled in the art and will not be described in detail here. Of course, the structure of the upper conveyor assembly 42 is not limited to this, and those skilled in the art can also choose other suitable structures based on the teachings of this utility model, such as a mesh belt conveyor assembly or a roller conveyor assembly, etc.

[0046] In some alternative embodiments, the first side conveying assembly 20 is a side belt conveying assembly, and the first side wrapping drive unit 21 is formed on the belt conveying surface of the side belt conveying assembly facing the wrapping conveying assembly 10. The friction between the belt conveying surface on the side of the side belt conveying assembly and the mattress drives the mattress to move, thereby realizing the conveying of the mattress. Of course, the structure of the side conveying assembly is not limited to this, and those skilled in the art can also choose other suitable structures based on the teachings of this utility model, such as a mesh belt conveying assembly or a roller conveying assembly, etc.

[0047] Please see Figure 3 In some optional embodiments, the side belt conveyor assembly includes a lifting frame 22, a side belt power module 23, two drive rollers 24, a side conveyor belt 25, and several side pressure rollers 26. The lifting drive assembly 30 is drivenly connected to the lifting frame 22. The side belt power module 23 is mounted on the lifting frame 22 and drivenly connected to the two drive rollers 24. The two drive rollers 24 are arranged from top to bottom on the lifting frame 22. The side pressure rollers 26 are positioned between the two drive rollers 24. The side conveyor belt 25 is arranged around the drive rollers 24 and the side pressure rollers 26. A first side wrapping drive unit 21 is formed on the side of the side conveyor belt 25 facing the wrapping conveyor assembly 10. Because the side belt conveyor assembly needs to be adaptively adjusted according to the height of the upper wrapping drive unit 421, the position where the mattress abuts against the side belt conveyor assembly is not fixed. Therefore, the side pressure rollers 26 are added to support the side conveyor belt 25 between the two drive rollers 24, preventing the end of the mattress from bending the side conveyor belt 25 and affecting the conveying of the mattress.

[0048] In some alternative embodiments, the second side conveying assembly 43 includes a plurality of side roll-up drive rollers 432 rotatably mounted on the mounting frame 41, with a second side roll-up drive portion 431 formed on the side of the side roll-up drive rollers 432 facing the roll-up space 11. When the side roll-up drive rollers 432 rotate, the friction between the outer peripheral surface of the side roll-up drive rollers 432 and the mattress causes the mattress to move.

[0049] The specific structure of the lifting drive assembly 30 can be selected according to actual needs. For example, the lifting drive assembly 30 can be a lead screw drive assembly, a rotary motor translation drive assembly 50, a belt translation drive assembly 50, a cylinder translation drive assembly 50, or a linear motor translation drive assembly 50, etc., and is not limited to this example. In this embodiment, the lifting drive assembly includes two lifting racks 31, two lifting gears, and a lifting drive motor. The two lifting racks 31 are respectively arranged on both sides of the lifting frame. The lifting gears are rotatably arranged on the lifting frame and mesh with the lifting racks 31. The lifting drive motor is arranged on the lifting frame and is driven by the lifting gears. The lifting drive motor drives the lifting gears to rotate, thereby causing the lifting gears to rise and fall along the lifting racks 31, thus driving the lifting frame to rise and fall. This design helps to improve the accuracy of the lifting frame and avoids the low accuracy caused by using cylinder-type drive assemblies. It should be clarified that the first side conveying component 20 in this utility model adopts a straight up and down lifting method, rather than a flip-type lifting method. If a flip-type lifting method is adopted, the flipping of the first side conveying component 20 will also change the diameter of the roll space 11, and it will be impossible to roll it into a long cylindrical roll with a smaller diameter.

[0050] In some alternative embodiments, the wrapping machine's wrapping drive mechanism further includes an inclined guide rail 60 that extends inclinedly between the wrapping conveyor assembly 10 and the first side conveyor assembly 20. A mounting frame 41 is movably engaged with the inclined guide rail 60 and moves along the inclined guide rail 60 under the drive of the translation drive assembly 50. The angle of the inclined guide rail 60 needs to be adjusted according to the actual situation so that when the mounting frame 41 moves along the inclined guide rail 60, the change in the height difference between the upper package drive unit 421 and the package conveying assembly 10 needs to match the change in the distance between the first side package drive unit 21 and the second side package drive unit 431. This achieves the purpose of synchronously adjusting the height difference between the upper package drive unit 421 and the package conveying assembly 10 and the distance between the first side package drive unit 21 and the second side package drive unit 431 when the mounting frame 41 moves. In this embodiment, the inclined guide rail 60 forms a 45° angle with the top of the package conveying assembly 10. When the mounting frame 41 moves along the inclined guide rail 60, the change in the height difference between the upper package drive unit 421 and the package conveying assembly 10 is the same as the change in the distance between the first side package drive unit 21 and the second side package drive unit 431.

[0051] In some alternative embodiments, a discharge guide plate 27 is provided on the side of the first side conveying assembly 20 away from the roll-up conveying assembly 10. The discharge guide plate 27 gradually tilts downward in the direction away from the roll-up conveying assembly 10. After the mattress is rolled up, the first side conveying assembly 20 descends until the discharge guide plate 27 is at a height approximately level with the top of the roll-up conveying assembly 10. Then the mattress can move towards the first side conveying assembly 20 under the conveying of the roll-up conveying assembly 10. The top of the first side conveying assembly 20 can also help move the rolled-up mattress onto the discharge guide plate 27. After the mattress reaches the discharge guide plate 27, it rolls off the discharge guide plate 27.

[0052] In some optional embodiments, the wrapping machine's wrapping drive mechanism further includes a feeding conveyor assembly 70, which is located on the side of the first side conveyor assembly 20 away from the conveyor assembly. A discharge guide plate 27 is positioned between the first side conveyor assembly 20 and the feeding conveyor assembly 70. After rolling off the discharge guide plate 27, the mattress will move onto the feeding conveyor assembly 70. The conveying direction of the feeding conveyor assembly 70 is approximately parallel to the axis of the cylindrical rolled mattress, facilitating the feeding conveyor assembly 70 to move the cylindrical rolled mattress in a suitable posture to the next process. Typically, the next process requires the cylindrical rolled mattress to be placed into an explosion-proof bag. Therefore, the feeding conveyor assembly 70 moves the cylindrical rolled mattress in a direction parallel to the axis of the cylindrical rolled mattress, thereby facilitating the insertion of the head of the cylindrical rolled mattress into the explosion-proof bag.

[0053] In some optional embodiments, a baffle plate 71 is provided on the side of the unloading conveying assembly 70 away from the first side conveying assembly 20. After the mattress rolls off the discharge guide plate 27 and moves onto the unloading conveying assembly 70, the baffle plate 71 blocks the mattress, preventing it from rolling off the unloading conveying assembly 70. In this embodiment, a docking guide plate 72 is also provided on the side of the unloading conveying assembly 70 facing the first side conveying assembly 20. After the discharge guide plate 27 descends with the first side conveying assembly 20, the end of the discharge guide plate 27 corresponds to the end of the docking guide plate 72, allowing the mattress to roll from the discharge guide plate 27 onto the docking guide plate 72, and then from the docking guide plate 72 onto the unloading conveying assembly 70, improving the stability of mattress conveying.

[0054] The specific structure of the feeding conveyor assembly 70 can be selected according to actual needs. For example, the feeding conveyor assembly 70 can be a mesh belt conveyor assembly, a roller conveyor assembly, a chain conveyor assembly, a belt conveyor assembly, etc., and is not limited to this example.

[0055] Please see Figure 6 and Figure 7The aforementioned wrapping machine's wrapping drive mechanism can be applied to a wrapping machine, which includes the aforementioned wrapping drive mechanism. In this embodiment, the wrapping machine further includes a packaging film conveying mechanism 80 and a welding mechanism 90. The packaging film conveying mechanism 80 and the welding mechanism 90 are mounted on the mounting frame 41. The packaging film conveying mechanism 80 is used to convey packaging film into the wrapping space 11, while the welding mechanism 90 is used to weld the packaging film after the mattress is wrapped, thereby achieving a welded connection between different parts of the packaging film, thus preventing the packaging film from being stretched open by the mattress.

[0056] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
