They are widely used in machinery, metallurgy, construction, chemicals, pharmaceuticals, mining, oil fields, electric power and other industries. The aluminum toe cap of safety shoes can effectively protect the feet. They are generally produced through injection molding. The exterior of the blank after molding is relatively rough and needs to be polished.

[0003] After searching, it is found that a polishing device for processing aluminum toe caps of safety shoes is disclosed in Chinese patent documents [Application number: 202321931374.6; Publication number: CN 220330979 U]. This polishing device for processing aluminum toe caps of safety shoes includes a shell, a motor is fixedly connected to the bottom of the inner wall of the shell, a threaded rod is fixedly connected to the output end of the motor, a movable plate is slidably connected to the outer periphery of the threaded rod, a sliding rod is slidably connected to the middle of the movable plate, the sliding rod is fixedly connected to the bottom of the inner wall of the shell, the movable plate is slidably connected to the middle of the shell, a movable block is slidably connected to the top of the movable plate, the top of the movable block is fixedly connected to the motor, and the output end of the motor is fixedly connected to the polishing rod.

[0004] Although this patent realizes the free adjustment and polishing of the convex and curved surfaces of the aluminum toe cap of the safety shoe, thereby improving work efficiency and increasing the service life of the safety shoe, it is unable to replace the polishing roller with the corresponding grinding mesh according to the grinding requirements, so that the aluminum toe cap polished by the polishing roller with a single mesh is relatively rough.

The technical problem to be solved by the utility model is: how to replace polishing rollers with different grinding meshes to improve the applicable scenarios and grinding efficiency.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A polishing device for processing aluminum toe caps of safety shoes comprises a hand-held rod, a connecting seat is provided at the top of the hand-held rod, a pair of guide slide grooves are provided on the hand-held rod, buckle sliders are slidably connected in the two guide slide grooves, a pair of buckle grooves are provided in the connecting seat, one end of the buckle slider is buckled and fixedly matched with the buckle groove, a driving gear 1 is rotatably connected in the hand-held rod, driving screws are coaxially fixed on both sides of the driving gear 1, and the two driving screws are respectively threadedly connected to the corresponding buckle sliders, a driving motor is fixed in the hand-held rod, a driving gear 2 is coaxially fixed on the output end of the driving motor, a transmission toothed belt is connected to the driving gear 2 and the driving gear 1, a pair of driving frames are slidably connected to the connecting seat, polishing rollers are provided on the two driving frames, and a driving component for controlling the driving frames to perform clamping action is provided in the connecting seat.

[0008] The working principle of the utility model is: the driving motor can be used to drive the driving gear 2 to rotate, and the driving gear 2 further drives the driving gear 1 to rotate. After the driving gear 1 rotates, it will drive the driving screw to rotate, and the driving screw will drive the two buckle sliders to expand or retract through the threaded connection with the buckle slider, thereby realizing the fixed connection and disassembly between the connecting seat and the hand-held rod, realizing the ability of convenient disassembly and replacement, and facilitating the replacement of polishing rollers with different grinding meshes, thereby improving the applicable scenarios and polishing efficiency, and controlling the clamping gap of the polishing roller through the driving component, thereby facilitating the adaptation to materials of different thicknesses, further improving the applicable scenarios and efficiency, and the hand-held rod 1 is convenient for personnel to hold, and the structure is compact and easy to carry, and the curved materials can also be polished in all directions by personnel holding it.

[0009] The buckle assembly includes a pair of guide slots provided on the hand-held rod, a buckle slider slidably connected in the two guide slots, a pair of buckle slots provided in the connecting seat, and one end of the buckle slider is buckled and fixedly matched with the buckle slot.

[0010] By adopting the above structure, the fixed connection between the connecting seat and the hand-held rod can be achieved through the buckle fixing cooperation between the buckle slider and the buckle groove, which enables convenient disassembly and replacement, and facilitates the replacement of polishing rollers with different grinding meshes, thereby improving the applicable scenarios and grinding efficiency.

[0013] A non-slip rubber layer is fixed on the surface of the hand-held rod.

[0014] By adopting the above structure, the friction on the surface of the hand-held rod 1 can be increased through the anti-slip rubber layer to prevent it from falling off.

[0015] The driving assembly includes a bidirectional lead screw rotatably connected in a connecting seat and a regulating wheel arranged outside the connecting seat. The two driving frames are respectively threadedly connected to the corresponding threaded sections of the bidirectional lead screw, and the regulating wheel is fixedly connected to the same axis as one end of the bidirectional lead screw.

[0016] With the above structure, the bidirectional lead screw can be driven to rotate by the regulating wheel. After the bidirectional lead screw rotates, it will drive the driving frame to move, and further drive the polishing roller to expand and fold.

[0017] Compared with the prior art, the polishing device for processing aluminum toe caps of safety shoes has the following advantages:

[0018] 1. The fixed connection between the connecting seat and the hand-held rod is controlled by the buckle assembly, so that the polishing rollers with different grinding meshes can be easily replaced, thereby improving the applicable scenarios and grinding efficiency.

[0019] 2. The clamping gap of the polishing roller is controlled by the driving component to facilitate the adaptation of materials of different thicknesses and further improve the applicable scenarios and efficiency.

[0020] 3. The hand-held rod is convenient for people to hold, and the structure is compact and easy to carry. People can also perform all-round polishing work on curved materials by holding it. BRIEF DESCRIPTION OF THE DRAWINGS

After the driving gear 1 8 rotates, it will drive the driving screw 9 to rotate.
