Description

Technical Field

[0001] This application relates to the field of bag manufacturing, and in particular to an installation device for bag frame and bag cover. Background Technology

[0002] Currently, suitcases are generally composed of two shells. For example... Figure 1 and Figure 2 As shown, the case includes an outer shell, a middle frame mounted on the edge of the open end of the outer shell, an outer zipper, and an inner zipper connected to the middle frame. The case can be opened and closed by opening and closing the outer zipper between the two case shells. An inner lining or partition fabric can be installed inside the case shell via the inner zipper, creating a closed space to separate the items inside the two case shells.

[0003] In current manufacturing processes, the middle frame is typically connected to the outer and inner zippers via stitching or rivets. This exposes the stitching or rivets on the outer side of the middle frame, affecting its appearance. Therefore, a cover plate can be added to the outer side of the middle frame to conceal the stitching or rivets. However, how to install the cover plate onto the middle frame is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In order to install the cover plate onto the middle frame, this application provides an installation device for the middle frame and cover plate of a bag.

[0005] This application provides an installation device for the inner frame and lid of a bag, which adopts the following technical solution:

[0006] An installation device for a bag frame and a bag cover includes a worktable for placing the bag shell and a pressing mechanism mounted on the worktable. The pressing mechanism includes an inner pressure roller, an outer pressure roller parallel to the inner pressure roller, a drive assembly for driving the outer pressure roller closer to or away from the inner pressure roller, and a rotation drive assembly for driving the inner or outer pressure roller to rotate. A pressing gap is formed between the inner and outer pressure rollers for the frame and the cover to pass through.

[0007] By adopting the above technical solution, during installation, the middle frame is first placed over the inner pressure roller, so that the inner pressure roller abuts against the inside of the middle frame. Then, the cover plate is placed on the middle frame. The drive assembly brings the outer and inner pressure rollers closer until they cooperate to press a point on the cover plate onto the middle frame. Then, the rotation drive assembly rotates, driving the middle frame forward until the entire cover plate is pressed onto the middle frame, completing the cover plate installation. Finally, the outer and inner pressure rollers are separated, and the middle frame can be removed from the worktable. The operation is convenient and the installation is quick.

[0008] Optionally, the upper surface of the worktable includes a placement surface for placing the housing, and both the inner and outer pressure rollers are perpendicular to the placement surface.

[0009] By adopting the above technical solution, the housing can be stably placed on the placement surface and slide on the placement surface when the cover plate is installed, so that the entire cover plate can be smoothly pressed onto the middle frame.

[0010] Optionally, the drive assembly is connected to the outer pressure roller, and the rotation drive assembly is connected to the inner pressure roller.

[0011] Optionally, the inner pressure roller is rotatably connected to the worktable, and the rotation drive assembly includes a drive motor fixedly installed under the worktable, the drive motor being used to drive the inner pressure roller to rotate relative to the worktable.

[0012] By adopting the above technical solution, the number of parts covered by the housing is minimized, thus preventing interference between the housing and the rotary drive assembly during movement.

[0013] Optionally, the drive assembly includes a mounting block suspended above the placement surface, a drive component for driving the mounting block to move in a straight line, and a mounting frame for mounting the drive component on a workbench. The outer pressure roller is connected to the mounting block and is located between the mounting block and the placement surface.

[0014] By adopting the above technical solution, the outer pressure roller will not interfere with the worktable when it moves relative to the inner pressure roller, thus making the adjustment of the outer pressure roller smoother.

[0015] Optionally, the outer pressure roller is rotatably connected to the mounting block.

[0016] By adopting the above technical solution, the outer pressure roller and the cover plate experience rolling friction when the box shell moves forward, allowing the box shell to move more smoothly on the worktable.

[0017] Optionally, a gap is provided between the outer pressure roller and the placement surface.

[0018] By adopting the above technical solution, the outer pressure roller will not interfere with the worktable when it moves relative to the inner pressure roller, thus making the adjustment of the outer pressure roller smoother.

[0019] Optionally, the outer wall of the outer pressure roller is provided with an annular groove, which is used to accommodate the cover plate on the side away from the middle frame.

[0020] By adopting the above technical solution, the cover plate can be better positioned on the outer pressure roller, thereby allowing the outer pressure roller to better press the cover plate onto the middle frame.

[0021] Optionally, the worktable is provided with a limiting groove for the outer pressure roller to slide in a straight line, and the lower end of the outer pressure roller is embedded in the limiting groove and is spaced apart from the bottom of the limiting groove.

[0022] By adopting the above technical solution, the limiting groove has a limiting effect on the outer pressure roller, ensuring that the outer pressure roller remains in a state of being directly opposite to the inner pressure roller after movement, thereby ensuring that the cover plate can be stably pressed onto the middle frame.

[0023] Optionally, the driving component includes a first link rotatably connected to the mounting block, a second link rotatably connected to the end of the first link away from the mounting block, and an active motor that drives the second link to rotate.

[0024] By adopting the above technical solution, the second connecting rod is driven to rotate by the active motor, which in turn drives the mounting block to reciprocate along the limiting groove, thereby realizing the movement of the outer pressure roller closer to and further away from the inner pressure roller.

[0025] Optionally, the drive assembly includes a mounting block rotatably connected to the worktable at one end, a drive component for driving the mounting block to swing, and the outer pressure roller is connected to the swinging end of the mounting block.

[0026] In summary, this application includes at least one of the following beneficial technical effects: the cover plate can be conveniently, quickly, and stably pressed and installed onto the middle frame; during the installation process, the housing can be stably supported and move forward smoothly, and it is not easy for pressure damage or wear to occur due to excessive pressing or excessive friction during the installation process.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0038] Example 1

[0039] This application discloses an installation device for the inner frame and cover of a bag.

[0040] like Figure 3 and Figure 4 As shown, an installation device for a bag frame and a bag cover includes a workbench 2 and a pressing mechanism 3 mounted on the workbench 2. The upper surface of the workbench 2 includes a placement surface 21 for placing the bag shell 1. When pressing the cover 15, the bag shell 1 is placed on the placement surface 21 with its opening facing down. Through the operation of the pressing mechanism 3, the cover 15 is pressed and fixed to the frame 12.

[0041] like Figure 3 and Figure 5As shown, specifically, the pressing mechanism 3 includes an inner pressure roller 31, an outer pressure roller 32 parallel to the inner pressure roller 31, a drive assembly 33, and a rotary drive assembly 34 for driving the inner pressure roller 31 or the outer pressure roller 32 to rotate. Both the inner pressure roller 31 and the outer pressure roller 32 are perpendicular to the placement surface 21, and a pressing gap is formed between them for the middle frame 12 and the pressure cap to pass through. The drive assembly 33 is connected to the outer pressure roller 32 and is used to drive the outer pressure roller 32 closer to or further away from the inner pressure roller 31, thereby adjusting the size of the pressing gap. The rotary drive assembly 34 is connected to the inner pressure roller 31 and is used to drive the inner pressure roller 31 to rotate relative to the worktable 2.

[0042] Before installation, the pressure plate was already fitted onto the middle frame 12, but it was not firmly pressed in place. During installation, the middle frame 12 was first placed over the inner pressure roller 31, so that the inner pressure roller 31 abutted against the inside of the middle frame 12. The drive assembly 33 brought the outer pressure roller 32 and the inner pressure roller 31 closer together until they cooperated to press a point of the cover plate 15 onto the middle frame 12. Then, the rotation drive assembly 34 rotated the inner pressure roller 31, thereby causing the housing 1 to slide on the worktable 2. This process can be manually assisted in terms of direction to ensure that the movement trajectory of the housing 1 is consistent with its edge. During the movement of the housing 1, the cover plate 15 is gradually pressed onto the middle frame 12, completing the installation of the cover plate 15. Then, the drive assembly 33 moved the outer pressure roller 32 away from the inner pressure roller 31. At this point, the housing 1 lost the pressure from the inner and outer pressure rollers 31 and could be directly removed from the worktable 2. The entire process is convenient to operate and quick to install.

[0043] like Figure 3 and Figure 5 As shown, specifically, the inner pressure roller 31 passes through the worktable 2 and is rotatably connected to the worktable 2. The rotary drive assembly 34 includes a drive motor 341 fixedly mounted under the worktable 2, which drives the inner pressure roller 31 to rotate relative to the worktable 2. The drive motor 341 is mounted below the worktable 2, allowing the rotary drive assembly 34 to not occupy the placement surface 21, thus providing more space on the placement surface 21 to place the housing 1 and ensuring that the housing 1 does not interfere with the rotary drive assembly 34 during movement.

[0044] like Figure 3 and Figure 5As shown, specifically, the drive assembly 33 includes a mounting block 331 suspended on the placement surface 21, a drive component 332 for driving the mounting block 331 to move in a linear direction, and a mounting bracket 333 for mounting the drive component 332 on the worktable 2. The drive component 332 is a power component that outputs a linear drive pair, such as a pneumatic cylinder, hydraulic cylinder, or electric cylinder. The outer pressure roller 32 is rotatably connected to the mounting block 331, and the outer pressure roller 32 is located between the mounting block 331 and the placement surface 21. A gap is provided between the outer pressure roller 32 and the placement surface 21. The drive component 332 directly drives the mounting block 331 to move linearly, thereby driving the outer pressure roller 32 to move closer to or away from the inner pressure roller 31. During this process, the outer pressure roller 32 and the inner pressure roller 31 are always in a facing state, and when applying force to the housing 1, the force is applied to the same point inside and outside the housing 1, eliminating the problem of indentation and bending of the housing 1 due to two-point force application, thus reducing the defect rate.

[0045] like Figure 6 As shown, the outer wall of the outer pressure roller 32 is further provided with an annular groove 321, which is used to accommodate the side of the cover plate 15 facing away from the middle frame 12. The cross-sectional shape of the annular groove 321 is similar to the shape of the outer wall of the cover plate 15 facing away from the middle frame 12. The annular groove 321 acts as a limit for the cover plate 15, preventing the cover plate 15 from undergoing vertical displacement on the outer pressure roller 32 during the pressing process. Vertical displacement on the outer pressure roller 32 would cause the cover plate 15 and the middle frame 12 to misalign, resulting in pressing failure. Therefore, the annular groove 321 improves the success rate of pressing.

[0046] Example 2

[0047] like Figure 7 As shown, the difference between Embodiment 2 and Embodiment 1 lies in the driving component 332. The driving component 332 includes a first connecting rod 3321 rotatably connected to the mounting block 331, a second connecting rod 3322 rotatably connected to the end of the first connecting rod 3321 away from the mounting block 331, and a drive motor 3323 that drives the second connecting rod 3322 to rotate. A limiting groove 22 is provided on the worktable 2 for the outer pressure roller 32 to slide linearly. The lower end of the outer pressure roller 32 is embedded in the limiting groove 22 and spaced apart from the bottom of the limiting groove 22. The first connecting rod 3321, the second connecting rod 3322, and the mounting block 331 form a slider-linkage structure. During the rotation of the second connecting rod 3322 driven by the drive motor, the mounting block 331 can reciprocate along the limiting groove 22, thereby realizing the movement of the outer pressure roller 32 closer to and further away from the inner pressure roller 31.

[0048] In another embodiment, the drive assembly 33 also employs an oscillating mechanism. For example, the drive assembly 33 includes a mounting block 331 rotatably connected to the worktable 2 at one end, and a drive member 332 for driving the mounting block 331 to oscillate. The rotation axis of the mounting block 331 can be horizontal or vertical. The outer pressure roller 32 is connected to the oscillating end of the mounting block 331. The mounting block 331 rotates under the action of the drive member 332, thereby bringing the outer pressure roller 32 closer to the inner pressure roller 31. The drive member 332 is a cylinder that articulates between the worktable and the mounting block 331. Other driving methods can also be used to drive the outer pressure roller 32 closer to the inner pressure roller 31.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
