Description

Technical Field

[0001] This invention relates to the technical field of scissor processing and forming, specifically to an automatic polishing machine for the inner side of scissor rings. Background Technology

[0002] Scissors typically consist of two hinged blades, each with a cutting edge at the front and a handle at the rear. The two blades work together to cut, while the two handles are for the user to hold and apply force. Current handles include finger rings to accommodate fingers. To enhance user comfort and safety, these rings are manually polished using sandpaper. This manual operation is inefficient, and to ensure polishing efficiency and quality, the sandpaper is used at high speeds, posing significant safety risks associated with manual polishing. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic polishing machine for the inner side of scissor rings, which solves the problem of low efficiency and high safety hazards associated with manual polishing using sandpaper belts in the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] An automatic polishing machine for the inside of scissor rings includes a frame and a swing assembly, a polishing assembly, and a clamping assembly mounted on the frame. The swing assembly includes a swing plate and a first drive mechanism for driving the swing plate to swing in a horizontal plane.

[0006] The polishing assembly is mounted on the oscillating plate. The polishing assembly includes a driving pulley, a driven pulley, an abrasive belt, and a first motor. The first motor is connected to the driving pulley, and the abrasive belt is wound between the driving pulley and the driven pulley and driven by the first motor.

[0007] The clamping assembly includes a rotating arm, a clamp, and a second driving mechanism. The clamp is located at the end of the rotating arm and is used to clamp the shear body of the scissors. The second driving mechanism is connected to the rotating arm and is used to drive the rotating arm to rotate. When the sanding belt passes through the ring on the shear body and is wrapped around the active pulley and the passive pulley, the rotating arm drives the inner side of the ring to rotate circumferentially on the surface of the sanding belt to perform a polishing action.

[0008] Furthermore, the automatic polishing machine for the inner side of the scissor ring also includes a sliding mechanism connected to the passive pulley and used to drive the passive pulley closer to or away from the active pulley.

[0009] Furthermore, the sliding mechanism includes a guide rail, a sliding seat, and a sliding cylinder. The guide rail is disposed on the swing plate, the sliding seat is slidably connected to the guide rail, the driven pulley is disposed on the sliding seat, and the output end of the sliding cylinder is connected to the sliding seat and used to drive the sliding seat to slide along the guide rail.

[0010] Furthermore, the first driving mechanism includes a driving component, a rocker arm, and a first rotating shaft. The first rotating shaft is rotatably connected to the frame, and one end of the first rotating shaft extends out of the frame for connection with the swing plate. The rocker arm is disposed on the first rotating shaft, and the output end of the driving component is connected to the rocker arm, which drives the first rotating shaft to rotate. The driving component is a cylinder or an electric cylinder.

[0011] Furthermore, the first rotating shaft is also provided with a brake pad, and the frame is provided with a brake caliper that cooperates with the brake pad.

[0012] Furthermore, the second drive mechanism includes a second motor and a second rotating shaft connected to the output end of the second motor. The rotating arm includes a vertical part and a horizontal part. The vertical part is connected to the second rotating shaft. One end of the horizontal part is connected to the top of the vertical part. The clamp is located at the other end of the horizontal part.

[0013] This invention provides an automatic polishing machine for the inner side of scissor rings. The scissors to be polished are held by a clamp, with the upper and lower parts of the abrasive belt passing through the ring on the scissors. The abrasive belt runs under the drive of a pulley. A second drive mechanism drives a rotating arm to rotate, causing the clamp to rotate circumferentially on the surface of the abrasive belt. During the rotation of the clamp, the ring rotates, allowing the abrasive belt to polish the entire inner wall of the ring. A first drive mechanism drives a swing plate to swing to one side at a certain angle. The upper part of the abrasive belt contacts the right side of the arc-shaped sidewall of the ring, and the lower part of the abrasive belt contacts the left side of the arc-shaped sidewall. The right and left semicircular arcs of the arc-shaped sidewall of the ring are polished. Then... The first drive mechanism drives the swing plate to swing to the other side by the same angle. The upper and lower parts of the sanding belt can polish the left and right semicircular arcs of the arc-shaped sidewall of the ring. Combined with the previous swing of the swing plate and the rotation of the rotating arm, the arc-shaped sidewall of the entire inner side of the ring is polished. The polishing equipment in this embodiment can realize the automation of polishing the entire inner side of the scissor ring. Compared with the existing technology of manual polishing, its polishing efficiency and quality are higher, and it can also save labor costs. At the same time, since the scissors are held by the clamp for polishing, the safety hazards caused by the high speed of the sanding belt during manual polishing can be avoided.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Please see Figures 1-4This invention provides an automatic polishing machine for the inner side of scissors and rings, including a frame 1 and a swing assembly 2, a polishing assembly 3, and a clamping assembly 4 mounted on the frame 1. The swing assembly 2 includes a swing plate 201 and a first driving mechanism for driving the swing plate 201 to swing horizontally. The polishing assembly 3 is mounted on the swing plate 201 and includes a driving pulley 301, a driven pulley 302, an abrasive belt 303, and a first motor 304. The first motor 304 is connected to the driving pulley 301, and the abrasive belt 303 is wound between the driving pulley 301 and the driven pulley 302 and is driven by the first motor 304. A motor 304 drives the active pulley 301 to rotate, which in turn drives the sanding belt 303 to run in conjunction with the passive pulley 302. The clamping assembly 4 includes a rotating arm 401, a clamp 402, and a second drive mechanism. The clamp 402 is located at the end of the rotating arm 401 and is used to clamp the shear body 6 of the scissors. The second drive mechanism is connected to the rotating arm 401 and is used to drive the rotating arm 401 to rotate. When the sanding belt 303 passes through the ring 601 on the shear body 6 and is wrapped around the active pulley 301 and the passive pulley 302, the rotating arm 401 drives the inner side of the ring 601 on the shear body 6 clamped on the clamp 402 to rotate circumferentially on the surface of the sanding belt 303 to perform a polishing action.

[0021] Specifically, the shear body 6 of the scissors to be polished is clamped by the clamp 402, and the upper and lower parts of the sanding belt 303 pass through the finger ring 601 on the shear body 6 with the sanding surface facing the inner wall of the finger ring 601. Then, the sanding belt 303 is fitted onto the driving pulley 301 and the driven pulley 302, as shown. Figure 4As shown, since the diameters of both the driving pulley 301 and the driven pulley 302 are much larger than the diameter of the ring 601, the upper and lower sections of the sanding belt 303 will contact the inner wall of the ring 601. Driven by the driving pulley 301, the sanding belt 303 polishes the inner wall of the ring 601. The second drive mechanism drives the rotating arm 401 to rotate, causing the clamp 402 to rotate, making the inner side of the ring 601 rotate circumferentially on the surface of the sanding belt 303. Thus, during the rotation of the clamp 402, the ring 601 rotates, allowing the sanding belt 303 to polish the entire inner wall of the ring. Because the upper and lower sections of the sanding belt 303... Since a portion of the belt can simultaneously polish two opposite positions on the inner wall of the ring, in this embodiment, the second drive mechanism only needs to rotate the clamp 402 180° to achieve polishing of the entire inner wall of the ring. Then, the first drive mechanism drives the swing plate 201 to swing to one side at a certain angle, that is, the sanding belt 303 tilts to one side at a certain angle. At this time, the arc-shaped sidewall of the sanding belt 303 connected to the inner wall of the ring 601 abuts against the upper and lower parts of the sanding belt 303 respectively. When the swing plate 201 swings to the left at a certain angle, the upper part of the sanding belt 303 contacts the right side of the arc-shaped sidewall of the ring, and the lower part of the sanding belt 303... The upper part of the abrasive belt 303 contacts the left side of the arc-shaped sidewall of the ring. At this time, the rotating arm 401 rotates 180°, and only the right and left semicircular arcs of the arc-shaped sidewall of the ring 601 are polished. Then, the first drive mechanism drives the swing plate 201 to swing to the other side by the same angle, that is, the abrasive belt 303 tilts to the other side by the same angle. At this time, the upper part of the abrasive belt 303 contacts the left side of the arc-shaped sidewall of the ring, and the lower part of the abrasive belt 303 contacts the right side of the arc-shaped sidewall of the ring. When the second drive mechanism drives the rotating arm 401 to rotate 180° again to rotate the ring 601, the upper and lower parts of the abrasive belt 303... The left and right semicircular arcs of the partially polished ring's arc-shaped sidewalls, combined with the previous swing of the swing plate 201 and the rotational motion of the rotating arm 401, polish both sides of the entire ring's arc-shaped sidewalls. The polishing equipment in this embodiment can automate the polishing of the scissor ring 601. Compared with the prior art of manual polishing, its polishing efficiency and quality are higher, and it can also save labor costs. At the same time, since the scissor body 6 is clamped by the clamp 402 for polishing, the safety hazards caused by the high running speed of the sanding belt 303 during manual polishing can be avoided.

[0022] In a further preferred embodiment, the automatic polishing machine for the inner side of the scissor ring also includes a sliding mechanism 5 connected to the passive pulley 302 and used to drive the passive pulley 302 closer to or away from the active pulley 301. In this embodiment, the sliding mechanism 5 drives the passive pulley 302 closer to the active pulley 301, causing the sanding belt 303 to change from a taut state to a slack state, thereby facilitating the removal of the sanding belt 303 from the passive pulley 302. On the one hand, it can be used to polish the ring 601 that passes through the scissors, and on the other hand, it facilitates the disassembly of the scissor body 6 after polishing and the replacement of the worn sanding belt 303, ensuring the polishing quality. Specifically, the sliding mechanism 5 includes a guide rail 501, a sliding seat 502, and a sliding cylinder 503. The guide rail 501 is mounted on the swing plate 201, the sliding seat 502 is slidably connected to the guide rail 501, the driven pulley 302 is mounted on the sliding seat 502, and the output end of the sliding cylinder 503 is connected to the sliding seat 502 and used to drive the sliding seat 502 to slide along the guide rail 501, thereby causing the driven pulley 302 on the sliding seat 502 to move along the guide rail 501 to approach or move away from the driving pulley 301. The guide rail 501 can be a square linear guide rail directly mounted on the swing plate 201, or it can be implemented by two guide posts mounted on connecting seats mounted on the swing plate 201. In this embodiment, the guide rail 501 is preferably a guide post, with each end connected to the swing plate 201 by a connecting seat. Correspondingly, the bottom of the sliding seat 502 is provided with a guide hole that matches the guide post, and the driven pulley 302 is mounted on the third rotating shaft 305. The third rotating shaft 305 is rotatably connected to the upper end of the sliding seat 502 via a bearing housing, thereby ensuring the rotation of the driven pulley 302. During operation, the first motor 304 is turned off to stop the sanding belt 303 and the rotating arm 401 is reset. The sliding cylinder 503 drives the driven pulley 302 to approach the driving pulley 301, causing the sanding belt 303 to change from a taut state to a slack state. One end of the sanding belt 303 is removed from the driven pulley 302, and the shear body 6 is clamped onto the fixture 402. After the sanding belt 303 is passed through the ring 601, it is re-mounted on the driven pulley 302. Then, the sliding cylinder 503 drives the driven pulley 302 away from the driving pulley 301, causing the sanding belt 303 to change from a slack state to a taut state. Then, the machine is started for automatic polishing. After polishing is completed, the machine is stopped, the sanding belt 303 is loosened, one end of the sanding belt 303 is removed from the driven pulley 302 and taken out of the ring 601, and then the shear body 6 is removed from the fixture. This cycle is repeated.

[0023] In this embodiment, the first driving mechanism includes a driving component 202, a rocker arm 203, and a first rotating shaft 204. The first rotating shaft 204 is rotatably connected to the frame 1, typically via a bearing seat. One end of the first rotating shaft 204 extends out of the frame 1 to connect with the swing plate 201. In this embodiment, the frame 1 is preferably L-shaped. The first driving mechanism and the second driving mechanism are respectively located at the upper ends of the two intersecting parts of the frame 1. The swing plate 201 and the clamp 402 both extend out of the frame 1 and are located within the space enclosed by the L-shaped frame 1, meaning the axes of the first rotating shaft 204 and the second rotating shaft 404 are perpendicular to each other. This ensures that the clamp 402 and the swing plate... Both 201 have sufficient space to avoid structural interference. In this embodiment, the rocker arm 203 is mounted on the first rotating shaft 204. The output end of the drive member 202 is connected to the rocker arm 203, which drives the first rotating shaft 204 to rotate. The drive member 202 is located at the lower part of the frame 1 and is connected to the first rotating shaft 204 through the inclined rocker arm 203. The drive member 202 can be a pneumatic cylinder or an electric cylinder. In this embodiment, an electric cylinder is preferred. In this way, the reciprocating linear motion of the drive member 202 can be converted into the reciprocating rotational motion of the first rotating shaft 204 through the rocker arm 203, thereby driving the swing plate 201 to swing back and forth. Its structure is simple, the operation is convenient, and the stroke can be greatly shortened.

[0024] To ensure that the first drive mechanism stops immediately after the swing plate 201 completes its swing and resets, and to avoid the swing inertia of the swing plate 201 affecting the polishing quality, a brake pad 205 is provided on the first rotating shaft 204, and a brake caliper 206 that cooperates with the brake pad 205 is provided on the frame 1. In this way, when the swing plate 201 swings to the correct position, the brake caliper 206 can be controlled to cooperate with the brake pad 205 on the first rotating shaft 204 to achieve rotational braking of the first rotating shaft 204.

[0025] Furthermore, the second drive mechanism includes a second motor 403 and a second rotating shaft 404 connected to the output end of the second motor 403. The second motor 403 drives the second rotating shaft 404 to rotate, which in turn drives the rotating arm 401 to rotate, thereby driving the clamp 402 to rotate to achieve polishing of the ring 601. (Refer to...) Figure 2 As shown, the second motor 403 is connected to the second rotating shaft 404 through a transmission mechanism consisting of a sprocket and a chain, and is used to drive the second rotating shaft 404 to rotate. In this embodiment, the rotating arm 401 includes a vertical part and a horizontal part. The vertical part is connected to the second rotating shaft 404, one end of the horizontal part is connected to the top of the vertical part, and the clamp 402 is located at the other end of the horizontal part. In this way, the working space of the clamp 402 can be greatly increased, the quality and efficiency of polishing can be improved, and it can also adapt to the polishing needs of scissors of different sizes.
