Description

Technical Field

[0001] This invention relates to the field of material feeding, and in particular to an automatic material feeding and processing system for doors and windows. Background Technology

[0002] In the actual production process, the surface of door and window frames needs to be polished. If clamping is used during the polishing process, the clamped part will not be polished. Therefore, some are conveyed by a conveyor device and polished during the conveying process. However, in the process of conveying door and window frames by ordinary conveyor devices, the contact surface between the door and window frames and the conveyor device will always be unable to be polished, which affects the polishing efficiency. Summary of the Invention

[0003] In view of the above, the technical problem that this application aims to solve is how to comprehensively polish the door and window frames;

[0004] The purpose of this invention is to provide an automatic door and window feeding and processing system, including a conveying module and a grinding module.

The conveying wheels are driven to rotate by a driving component. The conveying wheels have annular grooves adapted to the door and window frame.

[0006] The polishing module includes a top and bottom polishing device, two side polishing devices, and two end polishing devices.

[0007] As a further improvement to the above scheme,

[0008] Preferably, the upper part of the conveyor wheel has a cavity, and a clamping assembly is installed in the cavity. The clamping assembly includes a central column, and multiple pin-connected frames are fixed on the top of the central column. Each pin-connected frame is rotatably connected to an n-shaped connecting rod through a pin shaft. The end of each n-shaped connecting rod is inserted into an annular groove. The included angles between the multiple n-shaped connecting rods are equal. An elastic support extending into the annular groove is installed on the frame through a bracket. The elastic support is located on the side away from the door and window frame.

The polishing wheels are driven to rotate by a motor, and the height spacing of the polishing wheels is adapted to the thickness of the door and window frame body.

[0011] Preferably, the two-sided grinding device includes a column-shaped grinding wheel driven by a motor, the side of which is adapted to the two sides of the door and window frame.

[0012] Preferably, the end-face grinding device includes a base plate, with conveyor belts installed on both sides of the base plate for clamping and transporting the sides of the door and window frame. A door and window frame positioning device is installed above the base plate. The positioning device includes a mounting plate capable of vertical reciprocating movement. Mounting rods capable of reciprocating along the length direction are installed on both sides of the mounting plate. A drive shaft is rotatably connected to both ends of the mounting plate via lugs. A first drive gear is fixed in the middle of the drive shaft, and second drive gears are fixed at both ends of the drive shaft.

[0026] Example

[0027] like Figure 1-4 As shown, an automatic door and window feeding and processing system includes a conveying module and a grinding module.

[0028] The conveying module includes a frame 5, on which multiple conveying wheels 2 are rotatably mounted via bearings. Each conveying wheel 2 has a cavity at its upper part, within which a clamping assembly is installed. The clamping assembly includes a central column, with multiple pin-connected frames 16 fixed to its top. Each pin-connected frame 16 is rotatably connected to an n-shaped connecting rod 15 via a pin shaft. The end of each n-shaped connecting rod 15 passes through an annular groove 14, and the included angles between the multiple n-shaped connecting rods 15 are equal. An elastic support extending into the annular groove 14 is mounted on the frame 5 via a bracket 18. Located on the side away from the door and window frame 1, the elastic support includes an arc plate 17, which is fixedly connected to the bracket 18 via an elastic telescopic rod. The conveyor wheel 2 forms a conveying channel adapted to the door and window frame 1. The conveyor wheel 2 is driven to rotate by a drive component. The conveyor wheel 2 has an annular groove 14 adapted to the door and window frame 1. The conveyor wheel 2 also has a belt groove. Multiple conveyor wheels 2 in the same row along the conveying direction are connected by belt drive. The motor drives one of the conveyor wheels 2 to rotate, and the other conveyor wheels 2 will rotate together.

[0029] The grinding module includes a top and bottom grinding device 3, two side grinding devices, and two end grinding devices. The top and bottom grinding device 3 includes a rectangular frame mounted on a frame 5. Multiple meshing grinding wheels are mounted on the upper and lower plates of the rectangular frame. The grinding wheels are driven to rotate by a motor. A pulley is fixed on the shaft of one of the upper grinding wheels, and a pulley is fixed on the shaft of one of the lower grinding wheels. The two pulleys are connected to the pulley on the output shaft of the motor via a belt. Therefore, the motor can simultaneously drive multiple grinding wheels on the upper and lower plates to rotate. When the door and window frame 1 passes over the upper and lower grinding wheels, the grinding wheels grind the upper and lower surfaces of the door and window frame 1. The height and spacing of the grinding wheels are adapted to the thickness of the door and window frame 1.

[0030] The two-sided grinding device includes a column-shaped grinding wheel 4 driven by a motor. The sides of the column-shaped grinding wheel 4 are adapted to the two sides of the door and window frame 1. The column-shaped grinding wheels 4, which are symmetrically arranged on both sides of the frame 5, are driven by a belt. The motor drives the column-shaped grinding wheels 4 on both sides to rotate, so as to grind the two sides of the door and window frame 1.

[0031] The two-end grinding device includes a base plate 6. Conveyor belts 13 are installed on both sides of the base plate 6 to clamp and transport the sides of the door and window frame 1. A positioning device for the door and window frame 1 is installed on the top of the base plate 6. The positioning device includes a mounting plate 11 that can move vertically back and forth. Mounting rods 8 that can slide back and forth along the length direction are installed on both sides of the mounting plate 11. The two ends of the mounting plate 11 are rotatably connected to a drive shaft through lugs. A first drive gear 10 is fixed in the middle of the drive shaft. A second drive gear 9 is fixed at both ends of the drive shaft. The second drive gear 9 meshes with the teeth on the upper side of the mounting rod 8. A grinding belt 7 is fixedly installed at the end of the mounting rod 8. A pressure plate 12 is installed on the lower part of the mounting plate 11 through an elastic telescopic rod. A vertical limiting support 20 is installed between the pressure plate 12 and the mounting plate 11. A vertical rod 21 is installed on the pressure plate 12. The teeth on the vertical rod 21 mesh with the first drive gear 10. A vertical limiting rod 19 is provided on the lower side of the pressure plate 12. A horizontal elastic telescopic rod is installed between the grinding belt 7 and the mounting rod 8.

[0032] The working principle of this application is as follows:

[0033] Two rows of drive wheels are provided on both sides of the frame 5. The distance between the two rows of drive wheels is adapted to the width of the door and window frame 1. Annular grooves 14 are opened on the drive wheels. The annular grooves 14 are at the same height, so the door and window frame 1 can be sent into the plane formed by the annular grooves 14. The downward side of the door and window frame 1 contacts the upper and lower surfaces of the annular grooves 14, and the two sides of the door and window frame 1 contact the side walls of the annular grooves 14.

[0034] The door and window frame 1 can be moved by the motor driving the transmission wheel to rotate.

[0035] Furthermore, along the conveying direction, there is a gap between adjacent transmission wheels. The upper and lower surface grinding device 3 and the two side surface grinding device are installed in the gap. The upper and lower surface grinding device 3 can grind the upper and lower surfaces of the door and window frame 1 at the same time, and the two side surface grinding devices can grind the two sides of the door and window frame 1. Since the door and window frame 1 is conveyed by the transmission wheel 2, the door and window frame 1 will pass through the gap completely, so the upper and lower surfaces and the two sides of the door and window frame 1 can be fully ground.

[0036] The conveyor wheel 2 is also equipped with a clamping assembly. During the rotation of the conveyor wheel 2, the n-shaped connecting rods 15 of the clamping assembly are pressed onto the upper surface of the door and window frame 1 in sequence, which can clamp the door and window in the conveying process, so that the door and window frame 1 can be continuously polished and will not move during the polishing process, making the polishing more precise.

[0037] After the door and window frame 1 is conveyed to the support plate, it will be conveyed forward by the conveyor belt 13. The pressure plate 12, which moves up and down at intervals, will press down. The vertical limit rod 19 passes through the inner frame of the door and window frame 1. When the door and window frame 1 is conveyed to the position, it will be limited by the vertical limit rod 19. Finally, after the pressure plate 12 is completely pressed on the upper part of the door and window frame 1, the elastic telescopic rod between the mounting plate 11 and the pressure plate 12 will be compressed. At the same time, the control switch will be triggered to stop the conveyor belts 13 on both sides. As the interval between the pressure plate 12 and the mounting plate 11 decreases, the vertical rod 21 will drive the first transmission gear 10 and the second transmission gear 9 to rotate, thereby driving the grinding belt 7 to move towards the center until the mounting plate 11 abuts against the vertical limit support 20. At this time, the grinding belt 7 is pressed on both ends of the door and window frame 1. The elastic telescopic rod between the grinding belt 7 and the mounting rod 8 is compressed, so that the two ends of the door and window frame 1 can be ground.

[0038] When the pressure plate 12 rises at intervals, the grinding belt 7 finishes grinding the two ends of the door and window frame 1. The elastic telescopic rod between the pressure plate 12 and the mounting plate 11 resets, triggering the control switch again to control the conveyor belts 13 on both sides to continue transmission. Similarly, after the two grinding belts 7 move away from the center and the vertical limit rod 19 is limited away from the door and window frame 1, the door and window frame 1 is transmitted forward by the conveyor belts 13 on both sides.

[0039] This completes all the polishing work. By repeating the above steps, the top and bottom surfaces, two sides, and two end surfaces of the door and window frame 1 can be polished continuously without any polishing dead corners due to the clamping action. At the same time, the door and window frame 1 can be continuously polished during the transmission process, and the door and window frame 1 is fixed by the pressing action during the polishing process, so that the door and window frame 1 will not shift during the polishing process and maintain the polishing accuracy.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
