Description

Technical Field

[0001] This application relates to the field of producing metal plates, wires, bars, tubes, profiles or similar semi-finished products by non-rolling methods, and specifically to a heat exchange copper tube surface cleaning mechanism. Background Technology

[0002] Utility model patent CN218079671U discloses a flat-head cutting mechanism for a drawing machine. The drawing machine includes a drawing die base, a feeding system, and a clamping mechanism mounted on the feeding system. The flat-head cutting mechanism includes a clamping assembly and a sawing assembly mounted on the feeding system, with the clamping assembly, sawing assembly, and clamping mechanism distributed sequentially away from the drawing die base. The feeding system drives the clamping mechanism, clamping assembly, and sawing assembly to move synchronously towards or away from the drawing die base. The clamping assembly and clamping mechanism clamp the workpiece, and the sawing assembly cuts the workpiece between the clamping assembly and clamping mechanism. When drawing and cutting copper tubes to a fixed length, both the shearing mechanism and the sawing mechanism cut the copper tube. The debris generated during cutting causes metal dust to adhere to the surface of the copper tube, affecting the product's appearance quality and increasing the difficulty of subsequent welding.

[0021] Reference Figure 1-2 This application proposes an embodiment of the heat exchange copper tube surface cleaning mechanism, which includes:

[0022] The rolling machine 10 has a limiting groove 11 for placing the heat exchange copper tube to be cleaned, and the rolling machine 10 is used to drive the heat exchange copper tube in the limiting groove 11 to roll.

[0023] The guide plate 20 is inclined between the drawing machine 70 and the rolling machine 10, and the side of the guide plate 20 away from the drawing machine 70 is inclined downward and extends to communicate with the limiting groove 11. The guide plate 20 is used to receive the heat exchange copper tubes sent out by the drawing machine 70 and transport them one by one into the limiting groove 11.

[0024] The exhaust cleaning machine 30 has an exhaust section distributed above the limiting groove 11. The exhaust cleaning machine 30 is used to generate negative pressure in the exhaust section to clean the surface of the heat exchange copper tube in the limiting groove 11.

[0025] After the drawing machine 70 completes the drawing and length cutting of the heat exchange copper tubes, the drawing machine 70 places the cut copper tubes one by one on the guide plate 20. The heat exchange copper tubes fall along the guide plate 20 and into the limiting groove 11. The exhaust cleaning machine 30 exhausts air above the limiting groove 11 to clean the metal powder on the surface of the heat exchange copper tubes. At this time, the rolling machine 10 drives the heat exchange copper tubes in the limiting groove 11 to roll, so that the exhaust cleaning machine 30 can fully adsorb and clean the metal powder on the surface of the heat exchange copper tubes.

[0026] The exhaust cleaning machine 30 includes a negative pressure box 31 connected to the exhaust mechanism, and the lower end of the negative pressure box 31 is provided with an exhaust port. In another embodiment, the size of the negative pressure box 31 matches the shape of the limiting groove 11, and the exhaust port below the negative pressure box 31 cleans and adsorbs all the heat exchange copper tubes in the limiting groove 11, but the energy consumption of the exhaust mechanism is relatively large;

[0027] In this embodiment, a walking mechanism 40 is also included. The exhaust cleaning machine 30 is mounted on the rolling machine 10 via the walking mechanism 40. The walking mechanism 40 is used to drive the exhaust cleaning machine 30 to move along the length direction of the heat exchange copper tube in the limiting groove 11. When the negative pressure box 31 moves, all the heat exchange copper tubes in the limiting groove 11 rotate synchronously, thereby achieving the cleaning of metal powder on the surface of the heat exchange copper tube.

[0028] In this embodiment, the rolling machine 10 includes a belt conveyor 12. The frame 121 of the belt conveyor 12 is provided with a baffle 13 on the side away from the guide plate 20. The two baffles 13 and the conveyor belt of the belt conveyor 12 form the limiting groove 11. When the conveyor belt of the belt conveyor 12 rotates, it drives the heat exchange copper tube in the limiting groove 11 to roll in place. Referring to the attached figure, the belt conveyor 12 includes multiple conveyor belts that are spaced apart along the conveying direction. Since there is a lot of metal powder adhering to the ends of the heat exchange copper tube after cutting, the multiple spaced conveyor belts in this application are distributed outside the ends of the heat exchange copper tube to avoid the problem of incomplete cleaning caused by the metal powder adhering to the ends of the heat exchange copper tube on the conveyor belt.

[0029] The limiting groove 11 can be designed to match multiple heat exchange copper tubes. After the heat exchange copper tubes fall into the limiting groove 11, the heat exchange copper tubes in the limiting groove 11 move away from the guide plate 20 under the action of the belt conveyor 12 until they approach the baffle 13. After multiple heat exchange copper tubes fall into the limiting groove 11 one by one, the multiple heat exchange copper tubes are arranged in sequence and fill the limiting groove 11. Then, the conveyor belt of the belt conveyor 12 rotates and drives all the heat exchange copper tubes in the limiting groove 11 to roll synchronously, so that the exhaust cleaning machine 30 can adsorb and clean the metal powder on the surface of all the heat exchange copper tubes.

[0030] It also includes a discharge collection device 50, which is disposed on the side of the frame 121 away from the guide plate 20. The baffle 13 on the side of the frame 121 away from the guide plate 20 is a baffle 13. The baffle 13 is rotatably mounted on the frame 121 and can be rotated to be vertical to limit the heat exchange copper tube to be cleaned in the limiting groove 11, or rotated to be tilted and placed on the discharge collection device 50 so that the cleaned heat exchange copper tube falls into the discharge collection device 50 along the baffle 13. The discharge collection device 50 can be designed as a hopper or a collection platform.

[0031] Reference Figure 2 As shown, after the heat exchange copper tube in the limiting groove 11 is cleaned by adsorption, the baffle 13 can be rotated to be placed on the discharge collection device 50 at an incline so that the cleaned heat exchange copper tube falls onto the discharge collection device 50 along the baffle 13. When the belt conveyor 12 is running, it can transport the cleaned heat exchange copper tube to the discharge collection device 50, so that the cleaned heat exchange copper tube can be transported out.

[0032] Specifically, the baffle 13 is vertically arranged and its lower end is rotatably connected to the frame 121. A drive assembly 60 is mounted on the frame 121. The drive assembly 60 is connected to the baffle 13 and is used to drive the baffle 13 to rotate. The baffle 13 is mounted on the frame 121 via a rotating shaft. The drive assembly 60 includes a motor and a worm gear assembly (not shown in the figure). The worm gear assembly is drively connected to the rotating shaft and the output shaft of the motor. The motor drives the rotating shaft to rotate, thereby driving the baffle 13 to rotate.

[0033] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
