Abstract
Description
Technical Field
[0001] This utility model relates to the field of rubber shoe sole processing, specifically a rubber shoe sole trimming device. Background Technology
[0002] Rubber soles are shoe soles made of rubber. Rubber sole materials can be divided into natural rubber or synthetic rubber. During the manufacturing process, prepared rubber blocks are placed in a pre-made mold for heating and vulcanization. After vulcanization, the cooled and shaped sole is removed from the mold and placed in the mold base of a trimming machine. A telescopic mechanism drives the blades to remove excess burrs, thus obtaining the finished rubber sole.
[0003] According to Chinese Patent No. CN217552907U, a rubber shoe sole trimming device is disclosed. This utility model corrects the position of the rubber shoe sole by installing a shoe sole positioning mold and a pressing mechanism on the workbench. It can achieve automated trimming with good trimming quality, eliminate safety hazards, and process multiple shoe soles at the same time, resulting in high work efficiency.
[0004] Regarding the aforementioned patent content, the device is equipped with a lifting mechanism and a cutter. The lifting mechanism allows the cutter to move downwards to trim and edge the rubber soles on the shoe mold. However, before and after trimming, workers need to reach under the cutter to remove or place the rubber soles to be trimmed. Since there are no limits on the cutter or the lifting mechanism, if the hydraulic cylinder suddenly malfunctions and causes the lifting mechanism to move the cutter downwards, the worker's hand may be cut, thus reducing the safety of the device during use. Utility Model Content
[0005] Therefore, the purpose of this utility model is to provide a rubber shoe sole trimming device to solve the technical problem of poor safety during device use.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a rubber shoe sole trimming device, comprising a base plate, a support frame fixed to the top of the base plate, and protective components on both sides of the support frame. Each protective component includes a through-hole extending through the upper sides of the support frame, a sliding groove formed on the lower sides of the support frame, a trigger switch installed on the upper sides of the base plate, and a sliding rod fixed to the sides of the support frame. A sliding seat is fitted onto the outer wall of the sliding rod, a side plate is fixed to one end of the sliding rod, and a third spring is installed between the side plate and the sliding seat. A baffle plate extending through the through-hole is fixed to one side of the sliding seat, a pulley is provided on one side of the side plate, and a steel wire rope extending through the side plate is fixed to one side of the sliding seat, with one end of the steel wire rope passing through the pulley and fitted with a pressure plate.
[0007] By adopting the above technical solution, when the pressure plate moves down, it will pull the steel wire rope. When the steel wire rope is pulled, it will pull the slide to move, and the slide will drive the baffle to move.
[0008] Furthermore, a rubber pad is installed at the bottom of the pressure plate, and the pressure plate is located directly above the trigger switch.
[0009] By adopting the above technical solution, the pressure plate can be moved down to press the trigger switch, which in turn activates the hydraulic cylinder.
[0010] Furthermore, a second spring is installed inside the lower part of the slide, and a sliding plate is connected to the top of the second spring. The sliding plate is fixedly connected to the pressure plate.
[0011] By adopting the above technical solution, when the pressure plate moves down, it will drive the slide plate to move down, so that the slide plate can squeeze the second spring, causing the second spring to be compressed.
[0012] Furthermore, a workbench is fixed inside the support frame, and two shoe molds are bolted to the top of the workbench.
[0013] By adopting the above technical solution, the rubber sole can be placed on the shoe mold.
[0014] Furthermore, a hydraulic cylinder is installed on the top of the support frame, and a lifting plate is installed at the output end of the hydraulic cylinder via a piston rod.
[0015] By adopting the above technical solution, the piston rod can be extended and retracted when the hydraulic cylinder is working, thereby driving the lifting plate to move.
[0016] Furthermore, a fixed frame is fixed on both sides of the top of the lifting plate, and a first spring is installed inside the fixed frame. A movable block is connected to the bottom end of the first spring.
[0017] By adopting the above technical solution, when the movable block moves upward, it will squeeze the first spring, causing the first spring to be compressed, which facilitates the subsequent pushing of the movable block downward to reset.
[0018] Furthermore, a movable rod penetrating the lifting plate is installed at the bottom of the movable block, and a pressure plate is installed at the bottom end of the movable rod.
[0019] By adopting the above technical solution, the pressure plate can press down on the rubber sole when it moves down, thereby improving the stability of the rubber sole.
[0020] Furthermore, mounting shells are bolted to both sides of the bottom of the lifting plate, and a cutter is installed at the bottom of the mounting shell. The pressure plate is located inside the mounting shell.
[0021] By adopting the above technical solution, the rubber shoe sole can be cut and trimmed when the cutter moves downward.
[0022] Furthermore, the two trigger switches are electrically connected to the hydraulic cylinder, and the pressure plate is slidably connected to the slide groove via a sliding plate.
[0023] By adopting the above technical solution, the hydraulic cylinder can be activated or deactivated by triggering the switch. When the pressure plate moves, it can drive the slide plate to slide inside the slide groove, thereby improving the stability of the pressure plate when it moves.
[0024] Furthermore, guide rods penetrating the support frame are installed on both sides of the top of the lifting plate.
[0025] By adopting the above technical solution, the lifting plate will drive the guide rod to move when it moves, so as to improve the stability of the lifting plate when it moves.
[0026] In summary, the present invention has the following main advantages:
[0027] 1. This utility model incorporates a protective component. When workers are picking up or placing rubber shoe soles, the top of the baffle contacts the bottom of the lifting plate, thus limiting the lifting plate's movement. This prevents a sudden malfunction of the hydraulic cylinder from causing the lifting plate to suddenly drop and potentially injuring the hands of those picking up or placing the rubber shoe soles. This enhances the protective effect and improves the safety of the device during use. When the hydraulic cylinder needs to be activated, the worker must press the touch plate with both hands. As the touch plate moves downward, it pulls the steel wire rope, which in turn pulls the slide block. The slide block then moves the baffle. When the baffle moves and no longer contacts the lifting plate, the touch plate continues to move downward. At this point, the touch plate presses the trigger switch, which activates the hydraulic cylinder, causing the lifting plate to move downward and the cutter to move downward for cutting and trimming the rubber shoe soles.
[0028] 2. This utility model improves the stability of the slide block when it moves by providing pulleys to guide the wire rope and sliding rods to guide the slide block.
[0029] 3. This utility model is equipped with a sliding plate, a sliding groove, and a second spring. When the pressure plate moves down, it will drive the sliding plate to slide inside the sliding groove, so as to improve the stability of the pressure plate when it moves. At the same time, the sliding plate will squeeze the second spring, so that the second spring is compressed and it is convenient to push the pressure plate up and reset in the future.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0038] The embodiments of this utility model will be described below based on its overall structure.
[0039] Example 1:
[0040] A rubber shoe sole trimming device, such as Figures 1-6As shown, the device includes a base plate 1, a support frame 2 fixed to the top of the base plate 1, protective components 9 on both sides of the support frame 2, a workbench 3 fixed inside the support frame 2, two shoe molds 4 bolted to the top of the workbench 3 for placing rubber soles on the shoe molds 4, a hydraulic cylinder 5 mounted on the top of the support frame 2, and a lifting plate 6 mounted on the output end of the hydraulic cylinder 5 via a piston rod. When the hydraulic cylinder 5 operates, the piston rod can extend and retract, thereby moving the lifting plate 6. Fixed frames 7 are fixed to both sides of the top of the lifting plate 6, and a first spring 8 is installed inside the fixed frame 7. A movable block 12 is connected to the bottom end of the first spring 8. When the movable block 12 moves... When block 12 moves upward, it will squeeze the first spring 8, causing the first spring 8 to be compressed, which facilitates the subsequent pushing of movable block 12 downward to reset. Movable rod 10 that passes through lifting plate 6 is installed at the bottom of movable block 12, and pressure plate 11 is installed at the bottom end of movable rod 10. When pressure plate 11 moves downward, it can first press down on the rubber sole to improve the stability of the rubber sole. Mounting shell 13 is installed on both sides of the bottom of lifting plate 6 by bolts. Cutter 14 is installed at the bottom of mounting shell 13. Pressure plate 11 is located inside mounting shell 13. When cutter 14 moves downward, it can cut and trim the rubber sole. Pressure plate 11 and cutter 14 correspond to shoe mold 4.
[0041] Specifically, the protective component 9 includes a through-hole 911 extending through the upper sides of both sides of the support frame 2, a slide groove 902 formed on the lower sides of both sides of the support frame 2, a trigger switch 901 installed on the top sides of the base plate 1, and a slide rod 913 fixed to both sides of the support frame 2. A slide seat 910 is fitted onto the outer wall of the slide rod 913. A side plate 908 is fixed to one end of the slide rod 913, and a third spring 909 is installed between the side plate 908 and the slide seat 910. A baffle 912 with a through opening 911 is fixed on one side. A pulley 907 is provided on one side of the side plate 908. A steel wire rope 906 passing through the side plate 908 is fixed on one side of the slide block 910. One end of the steel wire rope 906 passes through the pulley 907 and is equipped with a pressure plate 905. When the pressure plate 905 moves down, it will pull the steel wire rope 906. When the steel wire rope 906 is pulled, it will pull the slide block 910 to move. The slide block 910 will then drive the baffle 912 to move.
[0042] See Figures 1-5A rubber pad is installed at the bottom of the pressure plate 905. The pressure plate 905 is located directly above the trigger switch 901. When the pressure plate 905 moves down, it presses the trigger switch 901, causing the trigger switch 901 to activate the hydraulic cylinder 5. The two trigger switches 901 are electrically connected to the hydraulic cylinder 5. The operator must press both trigger switches 901 simultaneously with both hands to start or stop the hydraulic cylinder 5. The pressure plate 905 is slidably connected to the slide groove 902 via the slide plate 903, so that the trigger switch 901 can start or stop the hydraulic cylinder 5. When the pressure plate 905 moves, it can drive the slide plate 903 to slide inside the slide groove 902, thereby improving the stability of the pressure plate 905 when moving. The top of the baffle 912 fits against the bottom of the lifting plate 6. The baffle 912 is connected to the slide seat. 910 is slidably connected to slide bar 913. Slide bar 913 can guide slide block 910 and baffle 912, thereby improving the stability of slide block 910 and baffle 912 when they move. The first spring 8 and the third spring 909 are both made of stainless steel. The bottom side of baffle 912 and the top sides of lifting plate 6 are both set at an angle so that when lifting plate 6 moves up and resets, baffle 912 can be pushed towards slide block 910, avoiding baffle 912 from obstructing lifting plate 6 from moving up and resetting. The length of baffle 912 in contact with lifting plate 6 is less than the distance between touch plate 905 and trigger switch 901, so that baffle 912 can stop blocking lifting plate 6 when touch plate 905 does not press trigger switch 901, making it convenient for lifting plate 6 to move down.
[0043] Example 2:
[0044] Based on the above embodiment 1, the following structure will be set to facilitate the reset of the touch plate 905.
[0045] Specifically, a second spring 904 is installed inside the lower part of the slide 902, and a slide plate 903 is connected to the top of the second spring 904. The slide plate 903 is fixedly connected to the pressure plate 905. When the pressure plate 905 moves down, it will drive the slide plate 903 to move down, so that the slide plate 903 can squeeze the second spring 904, causing the second spring 904 to be compressed. The second spring 904 is made of stainless steel.
[0046] Example 3:
[0047] Based on the above embodiment 1, in order to improve the stability of the lifting plate 6 when it moves, it is necessary to guide the lifting plate 6, so the following structure will be set.
[0048] See Figures 1-5 Guide rods 15 that penetrate the support frame 2 are installed on both sides of the top of the lifting plate 6. When the lifting plate 6 moves, the guide rods 15 will move, thereby guiding the lifting plate 6 and improving the stability of the lifting plate 6 when it moves.
[0049] The working principle of this utility model is as follows: First, when using it, the operator can connect the power supply, then place the rubber sole on the shoe mold 4. Next, the operator presses the touch plate 905 with both hands simultaneously, causing the touch plate 905 to move downwards. When the touch plate 905 moves downwards, it will pull the steel wire rope 906. When the steel wire rope 906 is pulled, it will pull the slide 910 to move. The slide 910 will then drive the baffle 912 to move. When the baffle 912 moves and is no longer in contact with the lifting plate 6, the touch plate 905 will continue to move. As the lifting plate moves downward, the pressure plate 905 will press the trigger switch 901, which will activate the hydraulic cylinder 5. This will cause the lifting plate 6 to move downward and drive the pressure plate 11 and the cutter 14 to move downward. The pressure plate 11 will first contact the rubber sole. As the lifting plate 6 continues to move downward, the pressure plate 11 will press down on the rubber sole. At the same time, the movable block 12 will squeeze the first spring 8, causing the first spring 8 to be compressed. The lifting plate 6 will drive the cutter 14 to continue to move downward, which will cut and trim the rubber sole.
[0050] After the trimming is completed, the hydraulic cylinder 5 can retract the piston rod, thereby driving the lifting plate 6 to move upward. When the lifting plate 6 moves upward and resets, it can push the baffle 912 towards the slide 910, preventing the baffle 912 from obstructing the upward and reset movement of the lifting plate 6. When the lifting plate 6 is reset, the bottom of the lifting plate 6 is in contact with the top of the baffle 912. At this time, the baffle 912 can act as a barrier. Then, the worker can pick up the rubber shoe sole by hand and place the next rubber shoe sole to be trimmed. Since the baffle 912 limits the lifting plate 6, it prevents the hydraulic cylinder 5 from suddenly malfunctioning and causing the lifting plate 6 to suddenly move downward, which could cause the cutter 14 to cut the hand that is picking up or placing the rubber shoe sole, thereby improving the protection effect.
