Description

Technical Field

[0001] This utility model belongs to the field of grinding wheel manufacturing technology, specifically relating to a hole ring conveying device for a multi-cavity resin grinding wheel molding machine. Background Technology

[0002] Grinding wheels, also known as bonded abrasives, are circular discs with axial holes formed by bonding ordinary abrasive grains together with a binder. After the grinding wheel is formed, a perforated ring needs to be placed in the axial hole, and then a trademark is affixed to the surface of the grinding wheel. Currently, existing automatic feeding equipment for grinding wheel perforated rings is usually designed for single-cavity processing structures, resulting in low efficiency. For electrode groups with three or more cavities, conventional perforated ring feeding equipment is unsuitable in terms of structural layout and manufacturing cost. There is an urgent need to develop a perforated ring conveying device suitable for multi-cavity processing. Utility Model Content

[0003] This invention provides a perforated ring conveying device for a multi-cavity resin grinding wheel molding machine, which addresses the shortcomings described in the prior art.

[0004] The technical solution adopted in this utility model is as follows: A perforated ring conveying device for a multi-cavity resin grinding wheel molding machine includes a rotary magnetic transfer mechanism. The rotary magnetic transfer mechanism comprises a rotary power component, a rotary swing arm structure, and a magnetic suction structure. The output shaft of the rotary power component is connected to the rotary swing arm structure and drives the rotary swing arm structure to rotate. The magnetic suction structure is installed at the free end of the rotary swing arm structure. The rotary power component drives the rotary swing arm structure to rotate, causing the magnetic suction structure to move closer to and away from the perforated ring to be transferred. The magnetic suction structure remains vertical at all times, and the rotary swing arm structure provides assembly space for the multi-cavity workstation.

[0005] As a preferred embodiment of this utility model, the rotating swing arm structure includes a swing arm, a rotating drive wheel, a rotating driven wheel, and a magnetic mounting base. One end of the swing arm is connected to the output shaft of the rotating power component and rotates with the output shaft of the rotating power component. The rotating drive wheel is mounted on the output shaft of the rotating power component. The rotating drive wheel and the rotating driven wheel are connected by a transmission, and the rotating driven wheel is mounted on the free end of the swing arm and rotates relative to the swing arm. The magnetic mounting base is fixedly connected to the side end face of the rotating driven wheel. The rotating power component is a rotary motor. The rotating drive wheel and the rotating driven wheel use pulleys and are driven by a synchronous belt. Alternatively, a gear and rack transmission structure can be used. The rotating driven wheel is mounted to the free end of the swing arm through a rotating shaft. The rotating driven wheel can rotate relative to the rotating shaft, and the swing arm is driven to rotate around the output shaft of the rotary motor. The rotating drive wheel, the rotating driven wheel, and the magnetic structure rotate synchronously. Since the rotating driven wheel can rotate relative to the swing arm, the magnetic structure can swing while maintaining a vertical state under the combined effect of the two rotations.

[0006] As a preferred embodiment of this utility model, the rotary magnetic transfer mechanism further includes a rotary magnetic base, a rotary power component is mounted on the rotary magnetic base, the output shaft of the rotary motor is connected to a rotating shaft through a coupling, the rotating shaft is mounted on a rotating shaft upright plate through a bearing, and the rotating shaft upright plate is fixed on the rotary magnetic base, providing more favorable rotational support for the swing arm and the rotary drive wheel.

[0007] As a preferred embodiment of this utility model, a swing arm position detection sensor is installed on the rotating magnetic base, which is set on the side away from the material picking hole ring. A proximity switch is preferably used to detect the position of the swing arm rotation and represent the origin position of the rotation.

[0008] As a preferred embodiment of this utility model, it further includes a vibratory feeder and a positioning conveying mechanism. The positioning conveying mechanism is set on the output side of the vibratory feeder, and the rotary magnetic transfer mechanism is located on the discharge side of the positioning conveying mechanism. The vibratory feeder realizes the directional and continuous arrangement of the perforated rings and conveys them to the vibratory feeder outlet, where they fall onto the positioning conveying mechanism. After being conveyed by the positioning conveying mechanism, they are picked up by the rotary magnetic transfer mechanism and taken to the next process.

[0009] In a preferred embodiment of this utility model, the positioning conveying mechanism and the rotary magnetic transfer mechanism are mounted on the same base plate; the base plate is mounted on the first rotary lifting adjustment mechanism, which can change the height and deflection angle of the positioning conveying mechanism and the rotary magnetic transfer mechanism relative to the vibratory plate.

[0010] In a preferred embodiment of this invention, the positioning and conveying mechanism includes a conveying bracket, a conveying structure, and a perforated ring positioning structure. The conveying structure is installed inside the conveying bracket, with the feeding side of the conveying structure located at the discharge side of the vibrating plate. The conveying bracket has a perforated ring positioning structure on the discharge side of the conveying structure. The magnetic attraction structure moves closer to and further away from the perforated ring positioning structure under the drive of the rotating swing arm structure. The conveying structure uses a belt conveyor, and protective plates are also provided on both sides of the conveyor belt. The protective plates are adjustablely installed on the conveying bracket, and different sizes of perforated rings can be accommodated by changing the spacing between adjacent protective plates.

[0011] In a preferred embodiment of this invention, a perforated ring detection sensor is installed on the feeding side of the conveying structure on the conveying bracket; a perforated ring detection sensor is also installed on the conveying bracket at a position corresponding to the perforated ring positioning structure. The perforated ring detection sensor uses a proximity switch. The sensor is installed on the feeding side of the conveying structure to detect whether a perforated ring exists at the interface between the vibratory feeder and the conveying structure. If a perforated ring is present, the vibratory feeder stops vibrating, and the conveying structure begins conveying. The proximity switch at the perforated ring positioning structure detects whether the perforated ring has been conveyed to the correct position. If it has, the conveying structure stops conveying, and the rotary magnetic transfer mechanism removes the perforated ring.

[0012] In a preferred embodiment of this invention, the conveying bracket is mounted on the base plate via a second rotary lifting adjustment mechanism. This second rotary lifting adjustment mechanism can change the installation height and deflection angle of the positioning conveying mechanism relative to the vibratory feeder.

[0013] As a preferred embodiment of this utility model, the vibratory feeder is mounted on the third rotary lifting adjustment mechanism, which can change the setting height and setting angle of the vibratory feeder.

[0014] This utility model adopts a rotating swing arm magnetic attraction mechanism, which can be used in multiple mold cavities and multiple workstations. Furthermore, the installation height and installation angle of each mechanism can be adjusted, expanding the applicable hole ring specifications. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: A perforated ring conveying device for a multi-cavity resin grinding wheel molding machine, such as Figure 1 As shown, it includes a vibratory feeder 1, a positioning conveying mechanism 2, and a rotary magnetic transfer mechanism 3. The positioning conveying mechanism 2 is located on the output side of the vibratory feeder 1, and the rotary magnetic transfer mechanism 3 is located on the discharge side of the positioning conveying mechanism 2.

[0021] The vibratory feeder achieves the directional and continuous arrangement of the perforated rings and transports them to the vibratory feeder outlet, where they fall onto the positioning conveyor mechanism. After being transported by the positioning conveyor mechanism, they are picked up by the rotary magnetic transfer mechanism for the next process. In order to improve the overall applicability, the vibratory feeder 1 is mounted on the third rotary lifting adjustment mechanism 7, which can change the setting height and setting angle of the vibratory feeder.

[0022] Furthermore, the positioning conveying mechanism 2 and the rotary magnetic transfer mechanism 3 are mounted on the same base plate 4; the base plate 4 is mounted on the first rotary lifting adjustment mechanism 5, which can change the height and deflection angle of the positioning conveying mechanism and the rotary magnetic transfer mechanism relative to the vibratory plate.

[0023] like Figure 2 As shown, the positioning and conveying mechanism 2 includes a conveying bracket 21, a conveying structure 22, and a perforated ring positioning structure 23. The conveying bracket 21 is located on the base plate 4, and the conveying structure 22 is installed inside the conveying bracket 21. The conveying structure uses a belt conveyor. In order to prevent the perforated rings conveyed by the conveying structure from falling off the side, protective plates 25 are also provided on both sides of the conveyor belt. The protective plates are adjustablely installed on the conveying bracket. By changing the distance between two adjacent protective plates, perforated rings of different sizes can be accommodated.

[0024] The feeding side of the conveying structure 22 is located below the discharge side of the vibratory feeder 1. In order to detect the discharge status of the perforated ring of the vibratory feeder, a perforated ring detection sensor is installed on the feeding side of the conveying structure 22 on the conveying support 21. The perforated ring detection sensor is installed on the sensor mounting plate 24, which is horizontally mounted on the conveying support and higher than the discharge side of the vibratory feeder. The perforated ring on the vibratory feeder falls from below the sensor mounting plate onto the conveyor belt.

[0025] The conveying support 21 has a perforated ring positioning structure 23 on the discharge side of the conveying structure 22. The perforated ring positioning structure is the same as the positioning component structure in the patent announcement number CN 117361068 A and the automatic feeding device and method for grinding wheel perforated rings, and will not be described again here. A perforated ring detection sensor is installed on the conveying support 21 at a position corresponding to the perforated ring positioning structure 23. A sensor mounting plate is provided below the perforated ring positioning structure. The perforated ring detection sensor installed is the same as the second sensor in the patent announcement number CN 117361068 A and the automatic feeding device and method for grinding wheel perforated rings, and will not be described again here.

[0026] The conveying bracket 21 is mounted on the base plate 4 via the second rotary lifting adjustment mechanism 6. The second rotary lifting adjustment mechanism can change the installation height and deflection angle of the positioning conveying mechanism 2 relative to the vibratory plate.

[0027] The first, second, and third rotary lifting adjustment mechanisms have the same structure, all including a first rotary cylinder and a second rotary rod. The first rotary cylinder is provided with a lifting channel, and the second rotary rod passes through the lifting channel and can rotate relative to the lifting channel. Locking holes and locking bolts are provided on the side wall of the lifting channel. After the second rotary rod rotates and changes its height, the locking bolts tighten the second rotary rod and lock it in the first rotary cylinder.

[0028] like Figure 3 As shown, the rotary magnetic transfer mechanism 3 includes a rotary power component 31, a rotary swing arm structure 32, a magnetic structure 33, and a rotary magnetic base 34. The rotary power component 31 is mounted on the rotary magnetic base 34. The rotary power component 31 uses a rotary motor. The output shaft of the rotary motor is connected to a rotating shaft through a coupling. The rotating shaft is mounted on a rotating shaft upright plate 35 through a bearing. The rotating shaft upright plate is fixed on the rotary magnetic base 34, providing more favorable rotational support for the swing arm and the rotary drive wheel.

[0029] A swing arm position detection sensor is installed on the rotating magnetic base 34, located on the side away from the material pick-up ring. A proximity switch is preferred. The sensor is used to detect the position of the swing arm rotation and to represent the origin of the rotation.

[0030] The rotating arm structure 32 includes a swing arm 321, a rotating drive wheel 322, a rotating driven wheel 323, and a magnetic mounting base 324. One end of the swing arm 321 is connected to the output shaft of the rotating power component 31 and rotates with the output shaft of the rotating power component 31. The rotating drive wheel 322 is mounted on the output shaft of the rotating power component 31. The rotating drive wheel 322 is connected to the rotating driven wheel 323 in a transmission manner. The rotating driven wheel 323 is mounted on the free end of the swing arm 321 and rotates relative to the swing arm 321. The magnetic mounting base 324 is fixedly connected to the side end face of the rotating driven wheel 323, and the magnetic structure 33 is mounted on the magnetic mounting base 324.

[0031] The magnetic structure 33 is the same as the magnetic component in the authorized announcement number CN 117361068 A, automatic feeding device and method for grinding wheel hole rings, and will not be described again here.

[0032] The vibratory feeder achieves the directional and continuous arrangement of perforated rings and conveys them to the vibratory feeder outlet. When a perforated ring is detected at the junction of the vibratory feeder outlet and the conveyor belt, the vibratory feeder stops vibrating, and the conveying structure starts conveying the perforated rings to the perforated ring positioning structure. When a perforated ring is detected at the perforated ring positioning structure, the conveying structure stops conveying, the rotary motor rotates, and the rotary drive wheel and rotary driven wheel use pulleys and are driven by a synchronous belt. The rotary driven wheel is mounted to the free end of the swing arm through a rotating shaft. The rotary driven wheel can rotate relative to the rotating shaft, and the swing arm is driven to rotate around the output shaft of the rotary motor. The rotary drive wheel, rotary driven wheel, and magnetic attraction structure rotate synchronously. Since the rotary driven wheel can rotate relative to the swing arm, the magnetic attraction structure can swing while maintaining a vertical state under the combined action of the double rotation. The magnetic attraction structure picks up and transfers the perforated rings from the perforated ring positioning structure.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
