Description

Technical Field

[0001] The utility model relates to the technical field of abrasive belt deviation rectification, in particular to an abrasive belt deviation rectification mechanism for a sander. Background Art

[0002] The abrasive belt deviation rectification mechanism of a sander mainly has the following key functions: The accurate operation of the abrasive belt is crucial for the sanding effect. If the abrasive belt deviates, the roughness of the sanded surface will be inconsistent, and there may be problems such as local over-sanding or under-sanding. When the abrasive belt deviates, it may cause unnecessary friction and collision with other components of the sander, which will not only accelerate the wear of the abrasive belt but also may lead to premature damage of the abrasive belt. The deviation rectification mechanism can make the abrasive belt run on a normal track, reduce abnormal wear, thereby extending the service life of the abrasive belt and reducing production costs. In summary, the abrasive belt deviation rectification mechanism of a sander plays an indispensable and important role in ensuring sanding quality, extending the life of the abrasive belt, improving production efficiency, and reducing costs.

[0003] However, in the prior art, for example, Chinese Publication No.: CN213702913U, "An Abrasive Belt Deviation Rectification Mechanism for a Sander", this utility model discloses an abrasive belt deviation rectification mechanism for a wide belt sander, including a driving roller, an abrasive belt is wound around the driving roller, and an intermediate shaft is arranged at the axial position of the driving roller. A contact rod is embedded inside the driving roller, and electric telescopic rods are assembled at both ends of the contact rod. The electric telescopic rods are in transmission connection with the contact rod. The midpoint position of the contact rod is rotationally connected to the driving roller through a rotating shaft. A slider is arranged at the top of the electric telescopic rod, and the top and bottom ends of the electric telescopic rod are respectively rotationally connected to the slider and the intermediate shaft through hinges. In this utility model, through the synchronous expansion and contraction change of the two electric telescopic rods, the contact rod rotates around the rotating shaft.

[0004] However, this device does not have an induction deviation rectification structure and cannot rectify the deviation after sensing the deviation of the abrasive belt, so it cannot ensure that the abrasive belt maintains the correct position and direction during operation, and avoid problems such as uneven processing surfaces and inconsistent sand marks caused by the deviation of the abrasive belt. Therefore, the accuracy and quality of sanding processing are relatively low. The device does not have an automatic deviation rectification structure and cannot utilize the kinetic energy of the abrasive belt to automatically rectify the deviation of the abrasive belt, and manual intervention is required, which increases the labor cost. Summary of the Utility Model

[0005] The purpose of the present utility model is to solve the problems existing in the prior art. The device is not provided with an induction deviation correction structure, and it cannot correct the deviation after sensing the deviation of the sand belt. It is impossible to ensure that the sand belt maintains the correct position and direction during operation, and avoid problems such as uneven processing surfaces and inconsistent sand marks caused by the deviation of the sand belt. As a result, the precision and quality of sanding processing are relatively low. The device is not provided with an automatic deviation correction structure, and it cannot utilize the kinetic energy of the sand belt to automatically correct the deviation of the sand belt, requiring manual intervention and increasing the labor cost.

[0006] To achieve the above object, the present utility model adopts the following technical solutions: A sand belt deviation correction mechanism for a sander, including a bearing plate. Two side plates are fixedly connected to the top of the bearing plate. A first rotating rod is rotatably connected to the top of the bearing plate.

A second outer shell is fixedly connected to one side of the driven rod. A second through groove is formed on the second outer shell. The outer surface of the stress rod is arranged inside the second through groove. When the limiting rod moves, it will, through the action of the force-applying rod on the first through groove, cause the driving rod and the first extending rod to swing around the first rotating rod as the axis.

[0007] As a preferred embodiment, adjusting rods are rotatably connected to the top of both sides of the driven rod. A first rod sleeve is fixedly sleeved on the outer surface of the adjusting rod.

[0010] As a preferred embodiment, a shaft plate is fixedly connected to one side of the side plate close to the fixed rod. An induction rod is rotatably connected inside the shaft plate. A second rod sleeve is fixedly sleeved on the outer surface of the induction rod. When the sand belt deflects, it will first collide with the second rod sleeves on both sides. When the sand belt moves, the collision will generate frictional force, driving the induction rod to rotate inside the shaft plate.

[0011] As a preferred embodiment, a gear is fixedly connected to the bottom of the induction rod. The outer surface of the gear is meshed with the outer surface of the rack. The gear following the rotation of the induction rod will drive the rack under the meshing action, causing the limit rod to move inside the limit sleeve.

[0012] As a preferred embodiment, two driving rollers are rotatably connected to the inner sides of the two side plates. One end of one of the driving rollers extends out. The outer surfaces of the two driving rollers are drivingly connected with a sand belt. After the motor is powered on, it will drive the driving roller to rotate, and under the driving action of the sand belt, drive the sand belt to move.

[0013] As a preferred embodiment, two L-shaped rods are fixedly connected to one side of one of the side plates. A motor is fixedly connected to the inner sides of the two L-shaped rods.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-5 , the present utility model provides a technical solution: a belt deviation rectifying mechanism of a sander, including a bearing plate 1, two side plates 2 are fixedly connected to the top of the bearing plate 1, a first rotating rod 3 is rotatably connected to the top of the bearing plate 1, a driving rod 4 is fixedly connected to the top of the first rotating rod 3, first through grooves 5 are opened on both sides of the driving rod 4, a first extending rod 6 is fixedly connected to one side of the driving rod 4, a force-bearing rod 7 is fixedly connected to the top of the first extending rod 6, a second rotating rod 8 is rotatably connected to the top of the bearing plate 1, a driven rod 9 is fixedly connected to the top of the second rotating rod 8, a second outer extension shell 10 is fixedly connected to one side of the driven rod 9, a second through groove 11 is opened on the second outer extension shell 10, the outer surface of the force-bearing rod 7 is arranged inside the second through groove 11. When the limiting rod 16 moves, under the action of the force-applying rod 18 on the first through groove 5, the driving rod 4 and the first extending rod 6 swing around the first rotating rod 3 as the axis.

[0026] Such as Figures 1-5As shown, adjusting rods 12 are rotatably connected to the top of both sides of the follower rod 9. A first rod sleeve 13 is fixedly sleeved on the outer surface of the adjusting rod 12. When the adjusting rod 12 and the first rod sleeve 13 swing, the horizontal gap between the two first rod sleeves 13 will be reduced, and the sand belt 24 will be centered and adjusted.

[0027] As Figures 1-5 shown, a fixed rod 14 is fixedly connected to one side of the side plate 2. A limit sleeve 15 is fixedly connected to the side of the fixed rod 14 away from the side plate 2. A limit rod 16 is movably embedded in the inner surface of the limit sleeve 15. One end of the limit rod 16 is fixedly connected to a rack 17. The rotating gear 22 will drive the rack 17 under the meshing action, causing the limit rod 16 to move inside the limit sleeve 15.

[0028] As Figures 1-5 shown, one end of the limit rod 16 away from the rack 17 is fixedly connected to a force-applying rod 18. The outer surface of the force-applying rod 18 is arranged inside the first through groove 5. When the limit rod 16 moves, it will act on the first through groove 5 through the force-applying rod 18, causing the driving rod 4 and the first extension rod 6 to swing around the first rotating rod 3 as the axis.

[0029] As Figures 1-5 shown, a shaft plate 19 is fixedly connected to the side of the side plate 2 close to the fixed rod 14. An induction rod 20 is rotatably connected inside the shaft plate 19. A second rod sleeve 21 is fixedly sleeved on the outer surface of the induction rod 20. When the sand belt 24 deflects, it will first collide with the second rod sleeves 21 on both sides. When the sand belt 24 moves, the collision will generate friction, driving the induction rod 20 to rotate inside the shaft plate 19.

[0030] As Figures 1-5 shown, a gear 22 is fixedly connected to the bottom of the induction rod 20. The outer surface of the gear 22 is meshed with the outer surface of the rack 17. The gear 22 following the rotation of the induction rod 20 will drive the rack 17 under the meshing action, causing the limit rod 16 to move inside the limit sleeve 15. After the motor 26 is powered on, it will drive the transmission roller 23 to rotate, and under the transmission action of the sand belt 24, drive the sand belt 24 to transmit.

[0031] As Figures 1-5 shown, two transmission rollers 23 are rotatably connected to the inner sides of the two side plates 2. One end of one of the transmission rollers 23 extends out. The outer surfaces of the two transmission rollers 23 are drivingly connected with a sand belt 24.

[0032] As Figures 1-5 shown, two L-shaped rods 25 are fixedly connected to one side of one of the side plates 2. A motor 26 is fixedly connected to the inner sides of the two L-shaped rods 25. The output end of the motor 26 is fixedly connected to the extending end of the transmission roller 23. The motor 26 is fixed to one side of the side plate 2 through the L-shaped rod 25.

[0033] Working principle: First, turn on the external power supply of the motor 26. The model of the motor 26 is DOY106, and the rated power is 750W. The motor 26 is fixed on one side of the side plate 2 through the L-shaped rod 25. After the motor 26 is powered on, it will drive the transmission roller 23 to rotate, and under the driving action of the sand belt 24, drive the sand belt 24 to move. When the sand belt 24 deflects, it will first collide with the second rod sleeves 21 on both sides. When the sand belt 24 moves, the collision will generate frictional force, driving the induction rod 20 to rotate inside the shaft plate 19. The gear 22 that rotates with the induction rod 20 will drive the rack 17 under the meshing action, causing the limit rod 16 to move inside the limit sleeve 15. The limit sleeve 15 is connected to one side of the side plate 2 through the fixed rod 14. When the limit rod 16 moves, it will act on the first through groove 5 through the force application rod 18, causing the active rod 4 and the first extension rod 6 to swing around the first rotating rod 3 as the axis. When the force receiving rod 7 on the first extension rod 6 swings accordingly, it will act on the second through groove 11 on the second extension housing 10, causing the driven rod 9 to rotate in the opposite direction around the second rotating rod 8. When the adjusting rod 12 and the first rod sleeve 13 swing accordingly, they will reduce the horizontal gap between the two first rod sleeves 13 and center the sand belt 24. The bearing plate 1 at the bottom of the device plays a role in fixedly supporting the entire device.

[0034] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
