Description

Technical Field

[0001] This application relates to the technical field of porous microchannel flat tube processing equipment, and in particular to a feeding device for porous microchannel flat tube processing. Background Technology

[0002] In the processing of porous microchannel flat tubes, raw materials are typically stored and transported in the form of trays. Traditional feeding methods mostly rely on manual handling, which is not only labor-intensive but also inefficient. With the continuous expansion of production scale and the increasing demand for production automation, there is an urgent need for a high-efficiency and precise feeding device to meet production needs.

[0003] On the one hand, the material trays themselves are quite heavy, and manual handling can easily cause worker fatigue or even injury. Furthermore, manual operation makes it difficult to ensure consistent loading positions each time, which may affect the accuracy of subsequent processing steps. On the other hand, due to the often complex spatial layout of processing workshops, existing simple loading aids are insufficient to flexibly adapt to different site conditions. Moreover, during the lifting and moving of material trays, the lack of effective buffering and guidance can easily cause collision damage to the trays and the equipment itself, increasing production costs and affecting production continuity.

[0004] Chinese patent application number 2024109810690 discloses a feeding device for microchannel flat tube processing, including a hollow rectangular frame, a conveyor belt assembly, a clamping assembly, and detachable rollers. The conveyor belt assembly includes a left pulley, a right pulley, a conveyor belt, and a transmission gear. The clamping assembly includes a clamping cylinder fixedly connected to the frame and an end clamping plate connected to the clamping cylinder. The detachable rollers are evenly spaced within the end clamping plate and roll in contact with the conveyor belt. The feeding device clamps a pair of conveyor belts through the clamping assembly, ensuring the compression stress and friction between the conveyor belt and the flat tube, effectively guaranteeing the conveyor belt's transport of the flat tube. Furthermore, the clamping assembly is equipped with detachable rollers to reduce the friction between the clamping assembly and the conveyor belt. The detachable rollers can be disassembled.

[0005] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: the aforementioned patents do not allow for convenient movement of the material tray. Utility Model Content

[0006] To increase the convenience of feeding the material tray, this application provides a feeding device for processing porous microchannel flat tubes.

[0007] The multi-hole microchannel flat tube processing feeding device provided in this application adopts the following technical solution: it includes a fixed frame, a clamping mechanism on the fixed frame, the clamping mechanism including a claw for fixing the material tray, a crossbar on the fixed frame, a pulley mechanism for cooperating with the material tray at the end of the crossbar away from the fixed frame, a fixed pulley for changing the direction of the rope on the crossbar, a motor on the fixed frame, a winding wheel for storing the rope along the output shaft of the motor, when the winding wheel rotates, the material tray is lifted by the action of the rope and the pulley mechanism, a pushing mechanism is provided on the fixed frame and located in the middle of the claw, the pushing mechanism includes a push rod for moving the material tray to the position of the claw, and an air pump on the fixed frame for driving the push rod to move.

[0008] Optionally, there are multiple push rods, each corresponding to a claw. Each push rod includes a base rod fixed on a fixed frame. One end of the base rod is rotatably connected to a rotating rod. The rotating rod is a hollow structure and a telescopic rod. An airbag column for pushing its extension is provided inside the rotating rod. The airbag column is connected to an air pump.

[0009] Optionally, the rotating rod is provided with grooves, and there are multiple grooves that are evenly spaced along the length of the rotating rod, with a roller provided in each groove.

[0010] Optionally, the base rod has a placement groove at the end away from the fixed frame, and an airbag strip is placed in the placement groove. The airbag strip is connected to an air pump. There are multiple airbag strips arranged in sequence. A sliding plate is provided at the end of the airbag strip away from the placement groove. A sliding rod is provided on the rotating rod to cooperate with the sliding plate. A sliding groove is provided in the sliding rod. When the airbag strip is inflated and pushes the rotating rod to rotate, the sliding plate at the end of the airbag strip will move along the sliding groove.

[0011] Optionally, each airbag strip is fitted with a storage net on its outer wall, and a spring-loaded rope mechanism is provided in the placement groove, with the rope of the spring-loaded rope mechanism connected to the slide plate.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] 1. Through the cooperation of motor, winding wheel, rope and pulley mechanism, the material tray can be automatically lifted without manual handling, which greatly reduces the labor intensity of workers and improves the feeding efficiency. The air pump driven push mechanism can accurately move the lifted material tray to the chuck position to ensure the accuracy of material tray installation and provide stable initial conditions for subsequent processing.

[0014] 2. The push rod adopts a hollow telescopic rod structure and is driven to extend and retract by an air bladder column, which does not occupy too much space. The grooves and rollers on the rotating rod provide good guidance during the movement of the material tray toward the fixed frame, preventing collisions during the movement of the material tray.

[0015] 3. Multiple airbag strips are placed in the groove on the base rod, and the rotating rod is driven to rotate after the airbag strips are inflated. The multiple airbag strips improve the stability of the rotating rod during rotation, and the airbag strips themselves have a certain elasticity, which can buffer the impact force during the material tray transfer process.

[0016] 4. The design of the spring-loaded cord mechanism and the storage net improves the storage efficiency of the airbag strip. The spring-loaded cord mechanism assists in the reset of the rotating rod, and the storage net can effectively restrain the airbag strip, preventing it from becoming tangled or displaced during inflation and deflation.

The push rod 9 is bolted to the fixed frame 1. An air pump 10 for driving the push rod 9 to move is bolted on the fixed frame 1.

[0023] In one embodiment, according to the appendix Figure 3 As shown, there are multiple push rods 9, each corresponding to a claw 2. Each push rod 9 includes a base rod 11 bolted to a fixed frame 1. A rotating seat is bolted to one end of the base rod 11 near the fixed rod. A rotating rod 12 is rotatably connected to the base rod 11 via the rotating seat. The rotating rod 12 is hollow and telescopic. An airbag column 13 for extending the rotating rod 12 is installed inside. The airbag column 13 is connected to an air pump 10 via an air tube.

The rotating rod 12 has grooves with rectangular cross-sections. There are multiple grooves evenly spaced along the length of the rotating rod 12. Rollers 15 are rotatably connected to each groove.

[0024] In one embodiment, according to the appendix Figure 3 As shown, a placement groove 16 is provided at one end of the base rod 11 near the fixing frame 1. An air seat connected to the air tube is fixed in the placement groove 16 with screws. The air seat is prior art. An air bag strip 17 is connected to the end of the air seat away from the air tube. The air bag strip 17 is prior art. The air bag strip 17 is connected to the air pump 10. There are multiple air bag strips 17 arranged sequentially.

The motor is started, and the motor drives the winding wheel to rotate. The winding wheel winds up the rope and lifts the material tray. When the material tray is lifted to a height close to the chuck on the fixed frame, the air pump is started. The air bladder column is inflated and pushes the rotating rod out from the base rod. The air pump inflates the air bladder strip on the base rod. After the air bladder strip is inflated, it pushes the rotating rod to rotate around the end of the base rod at a certain angle. The roller on the rotating rod contacts the material tray. Under the rolling guidance of the roller, the material tray is pushed to the chuck position. The chuck fixes the material tray, the air pump stops supplying air, the gas in the air bladder column and air bladder strip is discharged, and the rotating rod slowly resets under the action of the spring-pulling rope mechanism, while retracting into the base rod under its own gravity.
