[0030] Example 1
[0031] like Figure 1-4 As shown, the present invention proposes a shoe sole trimming device, which includes a workbench 1, a support plate 2, a mounting base and a drive assembly;
[0032] The mounting base is rotatably mounted on the middle of the worktable 1 via a bearing and extends to the bottom of the worktable 1. The top of the mounting base is provided with a mounting groove 16. The inner side of the mounting groove 16 is provided with a limiting component for elastically extending to the outside of the mounting base in the use state. The limiting component is arranged facing the side of the mounting base.
[0033] The support plate 2 is set at the top of the mounting base, and its bottom end is wrapped around the outside of the mounting base and snapped into the end of the limiting component. It is used to support the sole of the shoe in use. The pressure plate pressed on the top of the support plate 2 can be connected to the mounting base in the same way. In order to improve the stability of the support plate 2 and the mounting base, the limiting component can be arranged through the bottom end of the support plate 2 when it extends to the outside of the mounting base.
[0034] The drive assembly is located below the worktable 1 and connected to the mounting base. In use, the drive assembly rotates on the worktable 1 via bearings, thereby causing the sole to rotate above the worktable 1 to perform edge trimming work around the sole.
[0035] In this embodiment, when the limiting component is installed inside the mounting groove 16, the end of the limiting component extends elastically outward to the mounting base. When the support plate 2 is installed on the top of the mounting base, the bottom end of the support plate 2 first wraps around the top outside of the mounting base, and compresses the end of the limiting component inward to the mounting groove 16. When the support plate 2 is in complete contact with the mounting base, the end of the limiting component extends elastically and engages with the support plate 2. The engagement between the end of the limiting component and the mounting base fixes the support plate 2 on the top of the mounting base, making the installation and removal of the support plate 2 more convenient. It also allows the support plate 2 to be replaced with different sizes for trimming different sizes of shoe soles.
[0036] Example 2
[0037] like Figure 3 As shown, the shoe sole trimming device proposed in this utility model differs from Embodiment 1 in that the mounting base includes a connecting column 4 and a rotating shaft 8.
[0038] The connecting column 4 is mounted in the middle of the worktable 1 via a bearing, and its top end is located above the worktable 1.
[0039] The rotating shaft 8 is located at the bottom center of the connecting column 4 and is connected to the drive assembly.
[0040] In this embodiment, the connecting column 4 is connected to the bearing of the worktable 1, and the top of the connecting column 4 is placed above the worktable 1, so that there is a gap between the support plate 2 and the worktable 1, which facilitates the trimming tool to trim the edge of the shoe sole. At the same time, the connecting column 8 is connected to the drive assembly to ensure that the power is stably transmitted to the connecting column 4 and drive the shoe sole to rotate smoothly.
[0041] Example 3
[0042] like Figure 3-4 As shown, the present invention proposes a shoe sole trimming device. Compared with the first embodiment, the difference in this embodiment is that the limiting component includes a locking block 12, a telescopic sleeve 13, and a spring 14.
[0043] The telescopic sleeve 13 is installed inside the mounting groove 16;
[0044] Spring 14 is located inside telescopic sleeve 13;
[0045] The locking block 12 is installed at one end of the telescopic sleeve 13, and its end is located outside the connecting column 4 and connected to the support plate 2.
[0046] In an optional embodiment, a fixing groove 15 is provided on the inner side of the mounting groove 16 and at the other end of the telescopic sleeve 13. The diameter of the locking block 12 is smaller than the diameter of one end face of the telescopic sleeve 13, which is used to prevent the end of the telescopic sleeve 13 from moving outward and falling off during use.
[0047] In an optional embodiment, the bottom end of the support plate 2 is provided with a sleeve 3, which is sleeved on the outside of the connecting post 4. The inner side of the sleeve 3 is provided with a slot 11, the size of which is arranged to match the end size of the locking block 12. This slot 11 is used to lock the end of the locking block 12 into the slot 11 during use, so that the locking block 12, through the elastic force of the spring 14 and in cooperation with the connecting post 4, limits the position of the sleeve 3, thereby limiting the position of the support plate 2.
[0048] In an optional embodiment, a rectangular block 9 is provided at the bottom end of the support plate 2 and in the middle of the sleeve 3, and a connecting groove 10 is provided at the top center of the connecting column 4. When the support plate 2 and the connecting column 4 are installed together, the rectangular block 9 is accommodated in the connecting groove 10. This is used to further limit the rotation between the support plate 2 and the connecting column 4 during use, so as to prevent the support plate 2 and the connecting column 4 from rotating relative to each other during the rotation of the connecting column 4, causing the sleeve 3 to compress the locking block 12 into the mounting groove 16, thereby improving the stability of the support plate 2 installation.
[0049] In this embodiment, the telescopic sleeve 13 is fixedly installed inside the mounting groove 16 by the fixing groove 15 and the elastic force of the spring 14, providing support for limiting the movement. At the same time, the spring 14 generates elastic force inside the telescopic sleeve 13, causing the telescopic sleeve 13 to elastically extend the end of the locking block 12 towards the outside of the connecting post 4 through the elastic force of the spring 14. When the support plate 2 drives the sleeve 3 to be sleeved downwards on the outside of the connecting post 4, the sleeve 3 contacts and presses the end of the locking block 12, forcing the locking block 12 and the telescopic sleeve 13 to compress the spring 16. 4. Retract inward until the support plate 2 is fully in place. At this time, the end of the locking block 12 is exactly aligned with the locking groove 11. The spring 14 releases its elastic force and pushes the locking block 12 to reset outward, so that its end is firmly locked into the locking groove 11. This achieves quick and reliable locking between the support plate 2 and the mounting base, making the installation and removal of the support plate 2 convenient. At the same time, the rectangular block 9 at the bottom of the support plate 2 and the connecting groove 10 at the top of the connecting column 4 form a positioning fit, further ensuring the installation stability and making the shoe sole more stable when rotating and trimming on the support plate 2.
[0050] Example 4
[0051] like Figure 1-2 As shown, the shoe sole trimming device proposed in this utility model differs from Embodiment 1 in that the driving component includes a worm gear 5, a motor 6, and a worm wheel 7.
[0052] The worm gear 7 is installed at the bottom end of the rotating shaft 8;
[0053] The worm gear 5 is rotatably mounted on the bottom end of the workbench 1 and meshes with the worm wheel 7;
[0054] The motor 6 is mounted under the workbench 1 via a bracket and is connected to the worm gear 5 via a coupling.
[0055] In this embodiment, the motor 6 and the worm gear 5 are reliably connected through a coupling, so that the power of the motor 6 is transmitted to the worm gear 5. The rotational motion is transmitted to the worm gear 7 through the meshing of the worm gear 5 and the worm wheel 7, thereby driving the rotating shaft 8 installed at the bottom of the connecting column 4 to rotate. In turn, the rotating shaft 8 drives the support plate 2 to rotate through the connecting column 4, so as to achieve smooth rotation of the shoe sole, which is convenient for trimming operations. At the same time, the worm gear 5 and the worm wheel 7 ensure the smoothness and reliability of power transmission, and also have the effect of deceleration and torque increase, avoiding the situation where the motor 6 drives the rotating shaft 8 to rotate too fast.
[0056] In this invention, the connecting column 4 is connected to the bearing of the worktable 1, with the top of the connecting column 4 positioned above the worktable 1 and the bottom of the connecting column 4 extending below the worktable 1. Simultaneously, the telescopic sleeve 13 is fixedly installed inside the mounting groove 16 via the fixing groove 15 and the elastic force of the spring 14, providing support for limiting the movement. The spring 14 generates elastic force inside the telescopic sleeve 13, causing the telescopic sleeve 13 to elastically extend the end of the locking block 12 outwards from the connecting column 4. When the support plate 2 moves the sleeve 3 downwards onto the outside of the connecting column 4, the sleeve 3 contacts and presses against the end of the locking block 12, forcing the locking block 12 and the telescopic sleeve 13 to compress the spring 14 and retract inwards until the support plate 2 is fully in place. At this point, the end of the locking block 12 is aligned with the locking groove 11, and the spring 14 releases its elastic force, pushing the locking block... 12 is reset outwards, so that its end is firmly locked into the slot 11, thereby achieving quick and reliable locking between the support plate 2 and the mounting base, making the disassembly and assembly of the support plate 2 convenient. At the same time, the rectangular block 9 at the bottom of the support plate 2 and the connecting groove 10 at the top of the connecting column 4 form a positioning fit, further ensuring the installation stability. The motor 6 and the worm 5 are reliably connected through a coupling, so that the power of the motor 6 is transmitted to the worm 5. The rotational motion is transmitted to the worm wheel 7 through the meshing of the worm 5 and the worm wheel 7, thereby driving the rotating shaft 8 installed at the bottom of the connecting column 4 to rotate. In turn, the rotating shaft 8 drives the support plate 2 to rotate through the connecting column 4, so as to achieve smooth rotation of the shoe sole, which is convenient for trimming operations. At the same time, the worm 5 and the worm wheel 7 ensure the smoothness and reliability of power transmission, and also have the effect of deceleration and torque increase, avoiding the situation where the motor 6 drives the rotating shaft 8 to rotate too fast.
[0057] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
