Description

Technical Field

[0001] This utility model relates to insoles, and more particularly to an edge trimming device for insoles. Background Technology

[0002] Insoles are made of different materials such as EVA, rubber, and TPU, and are usually formed by injection molding or compression molding. During the production process, after the insole is initially formed, there will be sprue marks remaining on its curved sidewalls, so the insole needs to be trimmed.

[0003] The common method of trimming insoles involves manual trimming with a trimming knife, which can easily cut workers' hands and cause injury. To address this issue, Chinese Patent Application No. CN202322091988.4 discloses a trimming device. This device places the insole on a support plate and presses down on a long rod, causing the long rod to drive a connecting rod two to compress a slider two. This causes the slider two to move the trimming knife closer to the insole of the athletic shoe. When one end of the long rod is pressed down, that end rotates around a fixed axis, causing the long rod to simultaneously drive an abutment block to compress a limiting block three. This causes the limiting block three to move a pressure plate downwards, working in conjunction with the support plate to press the insole firmly. When the motor at the lower end of the rotating shaft is started, it rotates the shaft, causing the support plate to rotate, thus trimming the insole. This allows workers to trim the insole without directly contacting the trimming knife, effectively protecting them.

[0004] However, in the technical solutions disclosed in the above patents, the support plate does not have a calibration function. When the staff fixes the insole, the position of the insole is easily displaced, resulting in an unsatisfactory trimming effect on the insole. To address this problem, we propose an insole trimming device. Utility Model Content

[0005] This utility model proposes a trimming device for insoles, which solves the above-mentioned problems existing in the use of the prior art.

[0006] The technical solution of this utility model is as follows: a shoe insole trimming device includes an operating table, and a positioning sleeve that can be raised and lowered is installed inside the upper side of the operating table.

[0007] A mounting frame is installed on the upper side of the operating table. A mounting base that can move up and down is installed on the mounting frame. A cutting blade and a pressure plate are installed on the mounting base.

[0008] A further feature of this invention is that: an installation cavity is provided inside the operating table, a No. 1 cylinder is installed inside the installation cavity, a base plate is fixed to the end of the piston rod of the No. 1 cylinder, and the lower side of the positioning sleeve is fixed to the base plate.

[0009] A further feature of this invention is that a second cylinder is mounted on the mounting bracket, the mounting seat is mounted on the end of the piston rod of the second cylinder, and the cutting blade is fixed to the lower side of the mounting bracket.

[0010] The pressure plate is slidably connected to the lower side of the mounting base.

[0011] A further feature of this invention is that the cutting blade is an irregularly shaped ring-shaped blade, and the pressure plate is located inside the cutting blade.

[0012] A further feature of this invention is that sliding rods are symmetrically fixed on the upper side of the pressure plate, and the two sliding rods are slidably connected to the mounting base.

[0013] The mounting base has a content groove on its lower side, and a spring connects the bottom wall of the content groove to the upper side of the pressure plate.

[0014] A further feature of this invention is that: an installation groove is provided on the rear side of the operating table, a No. 3 cylinder is installed in the installation groove, a pushing component capable of moving left and right is installed on the piston rod of the No. 3 cylinder, and a moving groove for the pushing component to move left and right is provided through the upper side of the installation groove.

[0015] A further feature of this invention is that a feeding ramp is provided on the left side of the operating table.

[0016] In summary, the beneficial effects of this utility model are as follows:

[0017] When placing the insoles, the technicians place the insoles in the positioning sleeve to prevent them from shifting during the process of fixing their position. After the pressure plate presses down on the upper side of the insoles, the positioning sleeve moves downward until its upper edge is level with the upper side of the worktable, thereby avoiding unsatisfactory edge trimming of the insoles and ensuring the product quality of the insoles.

[0018] After the insole is trimmed, the pusher, driven by cylinder number three, moves the insole to the left, allowing it to leave the operating table via the feeding ramp, thus completing the automatic unloading process. This improves work efficiency and effectively reduces the workload of technicians. Attached Figure Description

[0024] The following will refer to the appendix in the embodiments of this utility model. Figure 1-3 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Example:

[0026] like Figures 1 to 3 As shown, a shoe insole trimming device includes an operating table 11. The operating table 11 has an upward-facing mounting cavity 17. A cover plate 29 is detachably installed on the upper side of the mounting cavity 17. A first cylinder 18 is installed in the mounting cavity 17. A base plate 19 is fixed to the end of the piston rod of the first cylinder 18. Two positioning sleeves 12 that match the shape of the shoe insole are fixed on the upper side of the base plate 19. A sliding groove 30 for accommodating the positioning sleeves 12 is opened in the cover plate 29. Under the drive of the first cylinder 18, the base plate 19 drives the two positioning sleeves 12 to move up and down in the sliding groove 30.

[0027] An mounting bracket 13 is installed on the upper side of the operating table 11. A second cylinder 20 is installed on the mounting bracket 13. A mounting seat 14 is fixed to the end of the piston rod of the second cylinder 20. A cutting blade 15 is fixed to the lower side of the mounting seat 14. The cutting blade 15 is an irregular ring-shaped blade that matches the shape of the insole.

[0028] Furthermore, a pressure plate 16 capable of moving up and down is installed on the lower side of the mounting base 14. The pressure plate 16 is enclosed within the cutting blade 15. The specific connection between the pressure plate 16 and the mounting base 14 is as follows: sliding rods 21 are symmetrically fixed on the upper side of the pressure plate 16. Both sliding rods 21 are slidably connected to the mounting base 14. A content groove 22 is opened in the lower side of the mounting base 14. A spring 23 is connected between the bottom wall of the content groove 22 and the upper side of the pressure plate 16. When no trimming operation is performed, the pressure plate 16 protrudes downward under the action of the spring 23, so that the lower edge height of the pressure plate 16 is lower than the lower edge height of the cutting blade 15.

[0029] The working principle of this utility model is as follows: Before the trimming operation begins, the two positioning sleeves 12 move upward under the drive of the first cylinder 18, and their upper ends protrude upward outside the upper side of the operating table 11. Then, the technician places the insole to be trimmed into the positioning sleeve 12, thereby positioning the insole and preventing its position from shifting.

[0030] After the insole is fixed in position, the second cylinder 20 drives the mounting base 14 to move downward. At this time, the positioning sleeve 12 moves downward a certain distance simultaneously, thereby reducing the exposed height of the positioning sleeve 12 to avoid interference with the cutting blade 15 during the descent of the mounting base 14, and to continue to limit the position of the insole.

[0031] After the pressure plate 16 abuts against the upper side of the insole, the mounting base 14 continues to move downward, so that the pressure plate 16 presses against the upper side of the insole. During this process, the positioning sleeve 12 moves downward again until the upper edge of the positioning sleeve 12 is flush with the upper side of the operating table 11. Then the cutting blade 15 follows the mounting base 14 to continue moving downward and cuts the sprue on the curved side wall of the insole, thereby trimming the edge of the insole.

[0032] It should be noted that in this embodiment, the size of the insoles without trimming is fixed so as to be compatible with the positioning sleeve 12 and the cutting blade 15.

[0033] To simplify the unloading process after the insole trimming is completed, Embodiment 2 is proposed: An installation groove 24 is provided on the rear side of the operating table 11. A third cylinder 25 is installed in the installation groove 24. A pushing component 26 capable of moving left and right is installed on the piston rod of the third cylinder 25. Initially, the pushing component 26 is located on the right side of the upper side of the operating table 11. A moving groove 27 for the pushing component 26 to move left and right is provided vertically through the upper side of the installation groove 24. A feeding ramp 28 is provided on the left side of the operating table 11. After the insole is trimmed, the mounting base 14 drives the cutting blade 15 and the pressure plate 16 to move upwards and no longer contact the insole. Subsequently, the pushing component 26, driven by the third cylinder 25, pushes the insole to the left, causing it to slide down the feeding ramp 28 into the storage container (not shown in the figure), thereby achieving automatic unloading and improving work efficiency.

[0034] It should also be noted that the terms used in this utility model, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this utility model.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
