Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum profile production, and in particular relates to an automatic feeding mechanism for aluminum profile surface polishing equipment. Background Art

[0002] During the production process of aluminum profiles, surface polishing equipment is required to polish the surface. The aluminum profile surface polishing equipment is basically composed of main components such as polishing wheels and feeding mechanisms. The feeding mechanism of existing polishing equipment generally uses a conveyor belt, and the polishing wheel is mounted above the conveyor belt. During the polishing operation, the aluminum profile workpiece to be polished is placed on the conveyor belt manually, and then the workpiece moves forward with the conveyor belt. When passing under the polishing wheel, the polishing and grinding are completed, and finally the conveyor belt continues to transport it to leave the polishing equipment from the discharge port. On the one hand, manual loading will inevitably increase labor workload and labor costs. On the other hand, in order to improve polishing efficiency and ensure polishing effect, the polishing wheel needs to exert a certain downward pressure on the surface of the aluminum profile workpiece during polishing. The conveyor belt is soft. In order to prevent the conveyor belt from sagging, a support plate or lower roller is required to be set on the back of the conveyor belt to lift the conveyor belt. The upper and lower sides of the conveyor belt are squeezed by the downward pressure and lifting force at the same time, which will not only accelerate the wear speed of the conveyor belt, but also easily cause equipment failures such as conveyor belt deviation, scratches and even tears, which invisibly increases the equipment maintenance workload and equipment operation costs.

[0003] In view of the above situation, the utility model provides an automatic feeding mechanism for aluminum profile surface polishing equipment.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] An automatic feeding mechanism for aluminum profile surface polishing equipment comprises a polishing device and a feeding conveyor belt arranged in front of the polishing device and a discharging conveyor belt arranged behind the polishing device. The polishing device comprises a polishing workbench and a polishing wheel arranged above the polishing workbench.

[0017] The technical solution of the present utility model will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments.

[0018] It should be noted that the terms "upper", "lower", "front", "back", "left", "right" and the like indicating directions or positional relationships are based on the drawings and are for the convenience of description only.

[0019] Example

[0020] like Figure 1-2 As shown, an automatic feeding mechanism for aluminum profile surface polishing equipment includes a polishing device 1 and a feeding conveyor belt 2 arranged in front of it and a discharging conveyor belt 3 arranged behind it. The polishing device includes a polishing workbench 4 and a polishing wheel 5 arranged above the polishing workbench. A feeding channel 6 for a workpiece 24 to be polished to pass through is arranged on the polishing workbench directly below the polishing wheel, and a feeding device is arranged below the feed channel.

[0021] The feeding device includes a spiral rubber roller 7, a feeding motor 8 and a feeding platform 9. The feeding platform is fixedly arranged at the inner bottom of the polishing device. According to the moving direction of the workpiece, the spiral rubber roller is rotatably mounted above the feeding platform in the front-rear direction. The spiral rubber roller is drivingly connected to the feeding motor. A spiral rubber ridge 10 is fixedly arranged on the outer side of the roller surface of the spiral rubber roller. The top of the roller surface of the spiral rubber roller is located in the middle of the feeding channel. During the polishing operation, the lower surface of the workpiece is in friction contact with the spiral rubber roller, forming an axial conveyance for the workpiece, and the upper surface of the workpiece is in friction contact with the polishing wheel, forming a grinding and polishing for the workpiece.

[0022] The outer sides of the front and rear ends of the spiral rubber roller are rotatably connected with external spherical seat bearings 11, and the bottom of the external spherical seat bearing is connected with an elastic support plate 12. The elastic support plate is telescopically connected to the feed platform through a guide rod spring 13, so that the height position of the spiral rubber roller can be elastically raised and lowered.

[0023] A driven friction wheel 14 is coaxially fixed to the outer side of the rear end of the spiral rubber roller. A V-shaped groove is annularly fixed on the outer peripheral surface of the driven friction wheel, and the two side walls of the V-shaped groove are arc-shaped surfaces. The feed motor is fixedly installed on the feed platform, and an active friction wheel 15 is installed on the motor shaft of the feed motor. An arc-shaped protrusion is annularly fixed on the outer peripheral surface of the active friction wheel. The arc-shaped protrusion of the active friction wheel and the V-shaped groove of the driven friction wheel can be in frictional contact in a clutched manner. On the one hand, the V-shaped groove of the driven friction wheel has a guiding function for the clutch engagement of the active friction wheel; on the other hand, the arc-shaped protrusion of the active friction wheel and the arc-shaped side wall of the V-shaped groove also have the function of increasing the friction contact surface, and can also allow the front and rear ends of the spiral rubber roller to have a slight prying shake. The selection of the outer spherical seat bearing is also to cooperate with the corresponding spiral rubber roller prying compatibility function.

[0024] When there is no aluminum profile workpiece in the feed channel, the spiral rubber roller is lifted up by the guide rod spring, at which time the active friction wheel and the driven friction wheel are separated, and the spiral rubber roller does not rotate; when an aluminum profile workpiece is fed, the workpiece enters the feed channel of the polishing equipment and comes between the spiral rubber roller and the polishing wheel. The upper surface of the workpiece is pressed downward by the polishing wheel, and the workpiece transfers the pressure downward, thereby pressing the bolt rubber roller down, and the friction action surfaces of the driven friction wheel and the active friction wheel form a mutual friction transmission, thereby driving the spiral rubber roller to drive the aluminum profile workpiece to feed along the axial direction until the grinding and polishing of the entire upper surface of the aluminum profile workpiece is completed, and finally the material is transported out of the polishing equipment through the discharge conveyor belt.

[0025] It should be noted that when there is no aluminum profile workpiece feeding, it is necessary to adjust the height distance between the polishing wheel and the spiral rubber roller to ensure that the height distance is less than the thickness of the aluminum profile workpiece. At the same time, it is also necessary to ensure that when there is aluminum profile workpiece feeding, the spiral rubber roller is pressed down and the friction transmission between the driven friction wheel and the active friction wheel can be effectively realized.

[0026] A polishing wheel bracket 16 is arranged above the polishing workbench, and the axle of the polishing wheel is connected to the bottom of the polishing wheel bracket in a liftable manner through an adjusting screw 17. The lower end of the adjusting screw is rotatably connected to the end of the axle of the polishing wheel. An adjusting nut 18 is fixedly arranged on the polishing wheel bracket, and the upper part of the adjusting screw is threadedly connected to the adjusting nut. A wrench part 19 is coaxially fixedly arranged on the upper end of the adjusting screw. The adjusting screw is driven to extend and retract up and down by using a wrench to realize the lifting and lowering adjustment of the polishing wheel.

[0027] Two rows of straightening wheels 20 are also arranged on the left and right sides of the feed channel to cooperate and guide the feed direction of the workpiece. Each straightening wheel is a horizontally rotatable nylon roller, and the upper and lower ends of the wheel axle of each straightening wheel are rotatably connected to the polishing workbench respectively.

[0028] One end of the active roller of the feed conveyor belt is drivingly connected to the feed motor 21, and a detection electric eye 22 is arranged between the feed conveyor belt and the polishing equipment, which is used to detect whether there is a workpiece above the junction between the feed conveyor belt and the polishing equipment. An electric control box 23 is arranged on the outside of the polishing equipment, and the detection electric eye and the feed motor and the feed motor are all electrically connected to the electric control box.

[0029] The electric control box is provided with a PLC automatic control circuit. When the polishing equipment is performing the aluminum profile polishing operation, the feed conveyor belt will temporarily stop feeding the aluminum profile workpiece; when the detection electric eye detects that there is no workpiece passing between the feed conveyor belt and the polishing equipment, the electric control box will automatically control the feed conveyor belt to start feeding, and when the workpiece feed passes the detection electric eye again, the automatic control circuit starts timing and controls the feed conveyor belt to keep delaying the feeding for a certain period of time before stopping, so as to ensure that the workpiece has entered under the polishing wheel of the polishing equipment and has started spiral conveying.

[0030] The technical solution of the present invention is not limited to the above-mentioned specific embodiments. Without departing from the scope and spirit of the described embodiments, many modifications and changes are obvious to ordinary technicians in this technical field. Any technical deformation made within the spirit and principles of the present invention falls within the protection scope of the present invention.
