The friction plate driven by the driving strip 7 can keep a state of being attached to the outer wall of the rotating cylinder 6 under the positioning action of the positioning mechanism and moves along with the rotating cylinder 6; when the friction plate moves to the two grinding pieces 9, the grinding pieces 9 rotate under the driving action of the edge grinding motor 8, the edge of the friction plate can be ground, and the effect of the position a is ground; the friction disc after finishing polishing continues to rotate along with the rotary drum 6 until the friction disc is separated from the rotary drum 6, and then a worker takes away the friction disc after finishing polishing, so that the polishing machine is simple and convenient. And the worker only needs to put the friction plate and take out the friction plate, and the processing efficiency is higher. Open the first hole of stepping down 10 on the backup pad 5 simultaneously and make edging motor 8's output shaft pass, so also make to polish and can realize.
The flexible positioning strip 13 has certain deformability, and the buffer spring 14 is a conventional spring; when the friction plate is driven to move, the friction plate is positioned in the middle part and the upper part of the rotating cylinder 6, and the position of the friction plate is stable at the moment; however, when the friction plate rotates and is in a vertical state or the opening is upward, the outer wall of the friction plate is limited by the flexible positioning strip 13, so that the friction plate can be continuously attached to the rotating cylinder 6; at the same time, the flexible positioning strip 13 is preferably made of wear-resistant material, so that the service life can be prolonged.
When the friction plate is polished and moves to the position of the second support rod 12, the friction plate is still driven by the driving strip 7, and when the friction plate passes over the second support rod 12, the friction plate falls off under the action of gravity, so that the friction plate is separated from the rotating drum 6 and falls onto the lower soft conveying belt 17 and is conveyed outside the machine body 1 of the conveying belt 17 by the conveying belt 17, and a worker can conveniently take and use the friction plate; wherein the driving roller 16 is externally connected with a motor for driving the driving roller 16 and the conveyor belt 17 to move. Meanwhile, the middle part of the conveyor belt 17 is arranged below the second supporting rod 12, so that the conveyor belt 17 also has a buffering function. While the conveyor 17 is below the bottom of the support frame 2 so that there is room for the friction plates to be fed out.
The two flexible positioning strips 13 limit the friction plate at the same time, so that the position stability of the friction plate can be further improved. The buffer spring 14 enables the flexible positioning strip 13 to be always kept in a tensioned state, so that excessive friction can be generated between the flexible positioning strip 13 and the rotating cylinder 6 and the driving strip 7, the flexible positioning strip 13 is guaranteed to have enough service life, meanwhile, the flexible positioning strip 13 can have enough acting force, and the friction plate is attached to the outer wall of the rotating cylinder 6. The support body 15 arranged on the inner wall of the support plate 5 can support the flexible positioning strip 13, and ensures that the flexible positioning strip 13 and the outer wall of the rotating cylinder 6 have enough distance difference, and meanwhile, the friction plate can normally enter the space between the flexible positioning strip 13 and the rotating cylinder 6, and the normal movement of the friction plate is ensured.
Along with the increase of the service time, the elastic acting force of the buffer spring 14 can be weakened, and the limiting effect of the flexible positioning strip 13 on the friction plate is weakened, at this time, the first support rod 11 needs to be rotated, and the length of the buffer spring 14 is increased, so that the flexible positioning strip 13 can have enough pressure to limit the friction plate (the method can play a role in adjustment to a certain extent, and if the first support rod 11 is rotated, the flexible positioning strip 13 cannot be guaranteed to have enough acting force, a new buffer spring 14 needs to be replaced).
When adjusting the angle of the first support lever 11, first, the worker holds the rotary disc 27 with one hand and pushes the palm against the outer wall of the rotary disc 27, then the worker grasps the two anti-slip portions 29 with the fingers, and then drives the two anti-slip portions 29 toward the rotary disc 27 in a pinching manner until the stabilizing cylinder 30 pushes the stopper 28, the tooth-shaped body 24 indicating this is released from the tooth-shaped groove 19, and then the worker can rotate the rotary disc 27 while pinching the anti-slip portions 29 and the rotary disc 27. At rolling disc 27 pivoted in-process, rolling disc 27 has driven actuating lever 26 and has rotated, and antiskid 29 has driven location cover 23 and has rotated, and actuating lever 26 can directly drive first bracing piece 11 and rotate, and location cover 23 also can drive first bracing piece 11 through movable rod 21 and rotate, and the effort that so whole hand was applyed can both drive first bracing piece 11 and rotate, and need not other instruments for the simple operation degree is higher.
After the first support rod 11 is rotated to a proper angle, the anti-slip part 29 is released, and under the elastic action of the fixed spring 22, the movable rod 21, the positioning cover 23, the tooth-shaped body 24, the anti-slip part 29 and the stabilizing head move towards the support block 18 until the last tooth-shaped body 24 is clamped in the tooth-shaped groove 19, so that the first support rod 11 is positioned simply and conveniently. Wherein if at an angle the tooth-shaped bodies 24 fail to snap into the tooth-shaped grooves 19, a suitable further rotation of the rotary disc 27 is sufficient, which is possible because the adjustment of the damping spring 14 does not need to be very precise.
After the tooth-shaped body 24 is clamped into the tooth-shaped groove 19, even if the buffer spring 14 has a pulling effect on the first support rod 11 and causes the first support rod 11 to have a rotation tendency, the movable rod 21 can play a clamping effect on the first support rod 11 because the longitudinal section of the movable rod 21 and the longitudinal section of the fixing hole 20 are both square; the movable rod 21 is limited by the tooth-shaped groove 19 through the positioning cover 23 and the tooth-shaped body 24, so that the positions of the positioning cover 23, the tooth-shaped body 24, the movable rod 21 and the first support rod 11 are fixed and cannot be driven to rotate; moreover, since the fixing spring 22 is continuously in the extended state, the fixing spring 22 can stably engage the tooth-shaped body 24 in the tooth-shaped groove 19, thereby ensuring the position stability of the first support rod 11.
The driving rod 26 passes through the movable rod 21 and the fixed spring 22 (both ends are fixedly connected with the inner walls of the movable rod 21 and the fixed hole 20 respectively), so that the whole fixed structure has stronger structural compactness; and when the stabilizing cylinder 30 is abutted against the stopping part 28, the tooth-shaped bodies 24 are separated from the tooth-shaped grooves 19, so that the worker can be prevented from excessively driving the anti-slip part 29 and the stabilizing cylinder 30 to move, and the fixing spring 22 is protected.
The antiskid parts 29 on both sides of the stabilizing cylinder 30 enable the operation convenience to be higher (in a pinching mode), and meanwhile, both ends of the antiskid parts 29 are respectively connected to the positioning cover 23 and the stabilizing cylinder 30, so that the shape stability of the antiskid parts 29 is ensured, and the service life of the antiskid parts is prolonged.
The movable rod 21 and the stabilizing cylinder 30 are movably sleeved on the driving rod 26, so that the driving rod 26 improves the motion stability of the movable rod 21 and the stabilizing cylinder 30, and also improves the motion stability of the positioning cover 23, so that the tooth-shaped body 24 at the end part of the positioning cover 23 can be better aligned with the tooth-shaped groove 19.
In the polishing process, an exhaust fan or a bag type dust collector and the like are arranged at the tail end of the dust collection pipe 32, so that the polished dust can be absorbed; wherein the closing plate 31 makes the absorption of dust better and reduces the amount of dust drifting to the outside. Meanwhile, the bottom and the top of the closing plate 31 are provided with dust suction pipes 32, so that the dust suction effect is better.
It should be noted that, in the present specification, the embodiments are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments may be referred to each other.
The above description is only for the purpose of describing the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention, and any variations and modifications made by those skilled in the art based on the above disclosure are within the scope of the appended claims.
