A feeding device for metal profiles

Abstract

This utility model discloses a metal profile feeding device. The metal profile is conveyed to the conveyor frame by the feeding rack and received by the conveyor rollers. The drive cylinder drives the clamping wheel to press the metal profile on the upper surface. The conveyor drive motor drives the power output rod to rotate and, through the belt, connects to all the conveyor rollers to convey the metal profile. Since the conveyor rollers are inclined to the conveying direction of the conveying plane and the included angle is less than 90 degrees, the metal profile will continuously move towards the inside of the conveying plane until it abuts against the limiting movable roller on the inside of the conveying plane during the forward conveying process. This ensures that the metal profile can be accurately conveyed to the traction machine at the specified position. The conveying speed of the conveyor rollers is greater than the conveying speed of the traction machine, so that the next metal profile can quickly catch up with the previous metal profile during the forward conveying process on the conveying plane, ensuring that all metal profiles enter the processing station in a continuous manner.

Description

Technical Field

[0001] This utility model relates to a feeding device, and in particular to a feeding device for metal profiles. Background Technology

[0002] During the processing of metal profiles, each profile needs to be transported and fed independently using a feeding device. Traditional feeding devices use a conveyor belt combined with a trumpet-shaped guide to adjust and control the feeding position of the metal profiles. However, this method has a small drawback: because the edges of the metal profiles are relatively sharp, they often impact the inner wall of the feeding device during contact. Over time, many small pits and depressions appear on the inner wall of the feeding device, causing the metal profiles to get stuck and jammed during subsequent feeding. This can lead to uneven feeding and require periodic grinding and repair of the inner wall of the feeding device. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to provide a feeding device that facilitates the feeding of metal materials.

[0004] The technical solution adopted by this utility model to solve the problem is: a metal profile feeding device, comprising:

[0005] A conveyor frame is provided with a conveying plane. Several horizontally arranged conveying rollers are arranged parallel to each other on the conveying plane. The conveying rollers are inclined to the conveying direction of the conveying plane and the included angle is less than 90 degrees. Vertically arranged limiting rollers are provided inside the conveying plane. Several pressing frames are provided on the conveyor frame along the front-back direction. The pressing frames are provided with a drive cylinder and a pressing wheel connected to the output end of the drive cylinder. The pressing wheel is located directly above the conveying plane. A detection sensor is provided at the rear end of the conveying plane.

[0006] A conveyor drive motor is arranged at the bottom of the conveyor frame. A power output rod is connected to the upper part of the conveyor drive motor and arranged along the conveying direction of the conveying plane. Several belts are sleeved on the power output rod. The belts are twisted and sleeved on the ends of the conveyor rollers, so that the power output rod synchronously drives all the conveyor rollers to rotate.

[0007] A feeding rack is arranged outside the conveyor rack. The feeding rack is equipped with several parallel conveyor belts facing the conveyor plane. A feeding drive motor is installed on the feeding rack. The feeding drive motor is connected to the conveyor belts through a connecting rod. A feeding sensor is installed on the feeding rack.

[0008] A traction machine is arranged at the end of the conveyor frame, and the traction speed of the traction machine is lower than the conveying speed of the conveyor roller.

[0009] As a further improvement to the above technical solution, a vertical rod is provided on the feeding rack, a mounting rod is pivotally connected to the bottom of the vertical rod, a clamping wheel is pivotally connected to one end of the mounting rod, a movable rod is pivotally connected to the other end of the mounting rod, a horizontal rod is provided at the top of the vertical rod, the end of the driving cylinder is pivotally connected to the horizontal rod, and the output end of the driving cylinder is pivotally connected to the front end of the movable rod.

[0010] As a further improvement to the above technical solution, a movable frame is provided at the bottom of the conveyor frame, and the limiting movable roller is arranged vertically on the movable frame. The limiting movable roller extends upward from the gap between the conveyor rollers to the transmission plane. The movable frame can move inward and outward at the bottom of the conveyor frame to adjust the position of the limiting movable roller on the transmission plane.

[0011] As a further improvement to the above technical solution, the two ends of the conveyor frame are respectively provided with supports arranged in the inward and outward directions, and the supports are provided with strip grooves. The two ends of the movable frame are respectively movably fixed in the strip grooves by locking members.

[0012] As a further improvement to the above technical solution, the locking component is provided with a labor-saving handle.

[0013] As a further improvement to the above technical solution, the end of the conveyor belt extends between the two conveyor rollers, and the height of the end of the conveyor belt is lower than the height of the top of the conveyor rollers.

[0014] The beneficial effects of this utility model are as follows: all metal profiles are arranged sequentially on the loading rack. During use, the loading rack transports the metal profiles to the conveying plane of the conveyor frame. A loading sensor detects and ensures that only one metal profile is transported to the conveyor frame each time. When the metal profile reaches the conveying plane, it is received by the conveyor rollers. A drive cylinder drives a pressure roller to press the metal profile against its surface to prevent it from jumping. The conveyor drive motor rotates the power output rod and connects it to all the conveyor rollers via a belt, thus driving all the conveyor rollers to transport the metal profile towards the front end of the conveying plane at the same speed. Because the conveyor rollers are inclined to the conveying direction of the conveying plane with an angle less than 90 degrees, the metal profile... As the metal profile is conveyed forward, it continuously moves towards the inside of the transmission plane until it comes into contact with the limiting rollers on the inside of the transmission plane. This ensures the accuracy of the metal profile's position, allowing it to be precisely conveyed to the traction machine at the designated location. When the tail end of the metal profile passes the detection sensor, it is determined that the metal profile on the transmission plane has been successfully fed. At this point, the loading rack can be controlled to convey the next metal profile onto the transmission plane. Since the conveying speed of the conveying rollers is greater than that of the traction machine, the next metal profile can quickly catch up with the previous metal profile as it is conveyed onto the transmission plane and forward along the transmission plane, thus ensuring that all metal profiles are connected end-to-end and enter the processing station.

[0023] Reference Figures 1 to 3 A metal profile feeding device, comprising:

[0024] A conveyor frame 10 is provided with a conveying plane, and a plurality of horizontally arranged conveyor rollers 11 are arranged parallel to each other on the conveying plane. The conveyor rollers 11 are inclined to the conveying direction of the conveying plane at an angle of less than 90 degrees. Figure 2 (As shown by reference numeral A), a vertically arranged limiting movable roller 12 is provided on the inner side of the conveying plane. Several pressing frames 13 are provided on the conveying frame 10 along the front-back direction. A driving cylinder 14 and a pressing wheel 15 connected to the output end of the driving cylinder 14 are provided on the pressing frame 13. The pressing wheel 15 is located directly above the conveying plane. A detection sensor 16 is provided at the rear end of the conveying plane.

[0025] A conveyor drive motor 17 is arranged at the bottom of the conveyor frame 10. A power output rod 18 is connected to the upper part of the conveyor drive motor 17 and arranged along the conveying direction of the conveying plane. Several belts 19 are sleeved on the power output rod 18. The belts 19 are twisted and sleeved on the ends of the conveyor rollers 11, so that the power output rod 18 synchronously drives all the conveyor rollers 11 to rotate.

[0026] The loading rack 20 is arranged outside the conveyor rack 10. The loading rack 20 is provided with several conveyor belts 21 that face the conveying plane and are parallel to each other. The loading rack 20 is provided with a loading drive motor 22, which is connected to the conveyor belts 21 through a connecting rod. The loading rack 20 is provided with a loading sensor.

[0027] The traction machine 30 is arranged at the end of the conveyor frame 10, and the traction speed of the traction machine 30 is lower than the conveying speed of the conveyor roller 11.

[0028] All metal profiles are arranged sequentially on the loading rack 20. During use, the loading rack 20 transports the metal profiles to the conveying plane of the conveyor rack 10. A loading sensor detects and ensures that only one metal profile is transported to the conveyor rack 10 at a time. When the metal profile reaches the conveying plane, it is received by the conveyor rollers 11. The drive cylinder 14 drives the pressure rollers 15 to press against the upper surface of the metal profile to prevent it from jumping. The conveyor drive motor 17 drives the power output rod 18 to rotate, and this rotation is connected to all the conveyor rollers 11 via a belt 19. This drives all the conveyor rollers 11 to transport the metal profile towards the front end of the conveying plane at the same speed. Because the conveyor rollers 11 are inclined to the conveying direction of the conveying plane at an angle less than 90 degrees, therefore... During the forward conveying process, the metal profile continuously moves towards the inner side of the transmission plane until it comes into contact with the limiting roller 12 on the inner side of the transmission plane. This ensures the accuracy of the metal profile's position, allowing it to be accurately conveyed to the traction machine 30 at the designated location. When the tail end of the metal profile passes the detection sensor 16, it is determined that the metal profile on the transmission plane has completed feeding. At this point, the loading rack 20 can be controlled to convey the next metal profile to the transmission plane. Since the conveying speed of the transmission roller 11 is greater than the conveying speed of the traction machine 30, the next metal profile can quickly catch up with the previous metal profile as it is conveyed to the transmission plane and forward along the transmission plane, thus ensuring that all metal profiles are connected end to end and enter the processing station.

[0029] Further optimization is achieved by providing a vertical rod on the loading rack 20. A mounting rod is pivotally connected to the bottom of the vertical rod, and the clamping wheel 15 is pivotally connected to one end of the mounting rod. A movable rod is pivotally connected to the other end of the mounting rod. A horizontal rod is provided at the top of the vertical rod, and the end of the drive cylinder 14 is pivotally connected to the horizontal rod. The output end of the drive cylinder 14 is pivotally connected to the front end of the movable rod. In this way, the drive cylinder 14 retracts, causing the mounting rod to swing via the movable rod, which in turn causes the clamping wheel 15 to swing downwards, ensuring that the clamping wheel 15 presses firmly against the upper surface of the metal profile. Simultaneously, the four-bar linkage formed by the horizontal rod, drive cylinder 14, movable rod, and the rear section of the mounting rod, along with the lever structure formed by the mounting rod pivotally connected to the vertical rod, controls the adjustment range and precision of the clamping wheel 15. Thus, the large stroke of the clamping wheel 15 can be controlled by the small stroke of the cylinder.

[0030] Further optimization is needed. Considering the different widths of metal profiles and the different mold sizes at the processing stations, the lateral positions of the ends of metal profiles of different specifications will also differ during loading. Therefore, a movable frame 40 is provided at the bottom of the conveyor frame 10. The limiting movable roller 12 is vertically arranged on the movable frame 40. The limiting movable roller 12 extends upward from the gap between the conveyor rollers 11 to the transmission plane. The movable frame 40 can move inward and outward at the bottom of the conveyor frame 10 to adjust the position of the limiting movable roller 12 on the transmission plane, thereby adjusting the lateral position of the metal profile during loading. In this solution, the movable frame 40 can be electrically adjusted by a motor. However, considering the low adjustment frequency of the movable frame 40 and the need for stability, it is preferable that the two ends of the conveyor frame 10 are respectively provided with brackets 101 arranged in the inward and outward directions. The brackets 101 are provided with strip grooves 102. The two ends of the movable frame 40 are respectively movably fixed in the strip grooves 102 by locking members 41. When the position of the movable frame 40 needs to be adjusted, loosen the locking member 41, adjust the position of both ends of the movable frame 40 on the strip groove 102, and then tighten the locking member 41. Preferably, the locking member 41 is provided with a force-saving handle 42, thereby saving the user the force required for adjustment. The locking member 41 can be a locking bolt or a rotating block, etc.

[0031] In this scheme, it is preferable that the end of the conveyor belt 21 extends between the two conveyor rollers 11, and the height of the end of the conveyor belt 21 is lower than the height of the top of the conveyor rollers 11, so as to ensure the stability of conveying the metal profile to the conveyor frame 10.

[0032] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
