[0001] The invention relates to the technical field of air duct processing equipment, and in particular to a turning and feeding device on an air valve forming line. Background Art

[0002] The air valve, also called the air volume regulating valve, is an indispensable central air-conditioning terminal accessory in the ventilation, air conditioning and air purification projects of industrial plants and civil buildings. It is generally used in air-conditioning and ventilation system pipes to adjust the air volume of the branch pipes. It can also be used for the mixing and adjustment of fresh air and return air.

[0003] When the air valve shell is formed, the bent and cut "U"-shaped sheet needs to be turned 180° and then fed into the forming machine for bending and forming. In the prior art, the most widely used sheet metal equipment is the cage-type turning mechanism, which occupies a large area and requires the entire huge cylinder to be turned over. The speed is relatively slow and it is also relatively dangerous. Therefore, we specially designed a smaller turning and feeding mechanism to improve production efficiency and reduce the risk of use.

DETAILED DESCRIPTION

[0019] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0020] like Figure 1 and Figure 2 As shown, a turning feeding device on a wind valve forming line includes a frame 1, a conveying roller, a turning frame, a conveyor belt 3 and a manipulator are arranged on the top of the frame 1, and the conveying roller and the conveyor belt 3 are parallel to each other; the conveying roller includes a plurality of parallel conveying rollers 21, and the frame 1 is provided with a motor that can drive the conveying rollers 21 to rotate synchronously, and the frame 1 is also provided with a baffle plate 22 at the tail end of the conveying roller; the turning frame includes a rotating shaft 41 and a plurality of clamping mechanisms, the rotating shaft 41 is located between the conveying roller and the conveyor belt 3, and the rotating shaft 41 is rotatably connected to the frame 1 through a plurality of mounting seats 42; each clamping mechanism is fixed on the rotating shaft 41 at intervals, and each clamping mechanism is located between two adjacent conveying rollers 21; a first servo motor 43 is fixed on the frame 1, and a sprocket 44 is provided between the output shaft of the first servo motor 43 and the rotating shaft 41 for transmission connection, and the first servo motor 43 can drive each clamping mechanism to swing back and forth between the conveying roller and the conveyor belt 3.

[0021] Working principle: The "U"-shaped sheet 6 that has been bent and notched is rolled into the device by the conveyor roller 21 with the opening facing upward, and continues to move forward until its front end is blocked by the material blocking plate 22 and stops. Each clamping mechanism is initially located below the conveyor roller 21. When the "U"-shaped sheet 6 is blocked and stops, the device will control the action of each clamping mechanism to clamp the "U"-shaped sheet 6; then, the first servo motor 43 is started, and the rotating shaft 41 is driven to rotate through the sprocket 44, so that each clamping mechanism swings upward and flips to the side where the conveyor belt 3 is located, thereby completing the 180° flip of the "U"-shaped sheet 6, and putting it down on the conveyor belt 3, and each clamping mechanism flips back to the initial position; then, the conveyor belt 3 is started, and the conveyor belt 3 transports the "U"-shaped sheet 6 to the entrance of the downstream bending equipment and stops; finally, the manipulator is started, clamps the "U"-shaped sheet 6, and sends it into the downstream bending equipment in a step-by-step action to complete multiple bending operations.

[0022] In the feeding equipment, each clamping mechanism is fixed on the rotating shaft 41 at intervals, so that the entire turning mechanism is in the shape of comb teeth, so that each clamping mechanism can sink to the bottom of the conveying roller 21, thereby making it easy to clamp the "U"-shaped plate 6, and it does not interfere with the subsequent action of turning the U"-shaped plate upside down. This elbow-type turning mechanism is not only simple in structure and occupies a small space, but also has a fast turning action and is safer in operation than a cage-type turning mechanism.

[0023] like Figure 3As shown, the manipulator includes a first slide rail 51 horizontally fixed on the top of the frame 1, and the first slide rail 51 is parallel to the conveyor belt 3; a first slide 52 is slidably connected to the first slide rail 51, and the first slide 52 is provided with a second servo motor 53 that can drive the first slide 51 to slide back and forth on the first slide rail 51; a cantilever 54 is fixed to the first slide 52, and a second slide rail 541 is vertically fixed to the cantilever 54, and a second slide 542 is slidably connected to the second slide rail 541; a first cylinder 543 that can drive the second slide 542 to slide up and down is fixed to the cantilever 54; a pair of clamps are provided on the second slide 542, and the two clamps are respectively located on both sides of the conveyor belt 3; each clamp includes a fixed arm 544, a movable arm 545 and a second cylinder 546, each movable arm 545 is hinged on the corresponding fixed arm 544, and each second cylinder 546 can drive each corresponding movable arm 545 to swing back and forth. A soft rubber block 547 is fixed at the clamping opening of each clamping jaw. Initially, the manipulator is located at the front end of the equipment. When the "U"-shaped sheet 66 stops on the conveyor belt 3, the second servo motor 53 and the first cylinder 543 are both started, so that the first slide 52 slides forward, and the second slide 542 slides downward, until one end of the "U"-shaped sheet 6 enters the clamping opening of the two clamping jaws, and then the two second cylinders 546 are actuated to drive the movable arms 545 of each clamping jaw to swing, thereby achieving the clamping of the "U"-shaped sheet 6; then, the second servo motor 53 moves forward step by step according to the set data, and each time it moves, the downstream bending equipment completes a bending operation, so that the "U"-shaped sheet 6 is accurately fed.

[0024] like Figure 1 , Figure 2 and Figure 4 Each clamping mechanism includes a swing arm 45 fixed on the rotating shaft 41, a stopper 46 is provided at the outer end of each swing arm 45, a third cylinder 47 is fixed on each swing arm 45, and a clamping block 48 is fixed on the push rod of each third cylinder 47. The clamping mechanism also includes a crossbar 49 spanning between the swing arms 45, and the crossbar 49 is detachably connected to each clamping block 48. Connecting multiple clamping blocks 48 together through a crossbar 49 allows us to appropriately reduce the number of third cylinders 47, and can also effectively avoid the smile error existing when each third cylinder 47 is in motion, making the clamping more stable.

[0025] like Figure 3 As shown, a rack 55 is also fixed on the top of the frame 1, and a gear 56 meshing with the rack 55 is fixed on the rotating shaft 41 of the second servo motor 53. The meshing gear 56 and the rack 55 enable the first slide 52 to accurately position, slide or stop, thereby making it more accurate in feeding the downstream bending machine.

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
