DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-2As shown, the present invention is a tobacco heat exchanger welding production line, wherein a plurality of conveying wheel assemblies 2 are symmetrically installed at both ends of a main frame 1, and a conveying drive assembly 3 for driving the conveying wheel assemblies 2 to rotate is installed on the main frame 1. The conveying drive assembly 3 drives the plurality of conveying wheel assemblies 2 to rotate, thereby realizing horizontal conveyance of the tobacco heat exchanger. The staff performs welding processing on the tobacco heat exchanger conveyed on the conveying wheel assembly 2 on the side of the main frame 1.

[0031] The conveying wheel assembly 2 mainly includes a wheel body 21 and a wheel axle 23, wherein baffles 22 are fixedly arranged at both ends of the wheel body 21, and the diameter of the baffles 22 is larger than the diameter of the wheel body 21. The baffles 22 on both sides play a limiting role for the tobacco heat exchanger placed on the wheel body 21 to prevent the tobacco heat exchanger from being offset during the conveying process. One end of the wheel axle 23 is fixedly connected to one group of baffles 22, and the other end is rotatably mounted on the main frame 1 through a bearing, and a driven sprocket 24 is also arranged on the wheel axle 23 to facilitate the conveying drive assembly 3 to drive the wheel body 21.

[0032] The conveying drive assembly 3 includes a first motor 31 fixedly mounted on the main frame 1, a driving sprocket 33 is fixedly mounted on the driving shaft 32 of the first motor 31, a driven sprocket 24 is fixedly mounted on the wheel shaft 23, the driving sprocket 33 is transmission-connected with multiple groups of driven sprockets 24 via chains 34, the first motor 31 drives the driving shaft 32 to rotate, the driving shaft 32 drives the driving sprocket 33 to rotate, and the transmission action of the chain 34 drives the multiple groups of driven sprockets 24 and the wheel body 21 to rotate, thereby realizing the overall conveying of the tobacco heat exchanger.

[0033] like Figure 3 As shown, a first steering assembly 4 for steering the heat exchanger is provided at one end of the main frame 1. When the tobacco heat exchanger is placed at one end of the main frame 1, the staff performs the first step of welding processing on the tobacco heat exchanger here, and during the welding process, the direction of the tobacco heat exchanger is changed by the first steering assembly 4. The specific reversing steps are:

[0034] The tobacco heat exchanger moves to the top of the first steering assembly 4 under the action of the conveying wheel assembly 2 and the conveying drive assembly 3. The first cylinder 42 on the steering bracket 41 drives the steering seat plate 43 to move upward, and lifts the tobacco heat exchanger through the steering placement plate 48, so that the lower end of the tobacco heat exchanger is separated from the conveying wheel assembly 2, ensuring that the tobacco heat exchanger remains stable during welding. Subsequently, the tobacco heat exchanger close to the staff side is welded. When one surface is welded, the second motor 46 drives the driving gear 47 to rotate, and drives the steering shaft 44 and the driven gear 45 to rotate through the gear meshing transmission, so as to realize the steering drive of the steering placement plate 48, thereby changing the end face of the tobacco heat exchanger facing the staff, and realizing welding processing of different end faces. In this process, the staff does not need to change their workstations, and the steering of the tobacco heat exchanger does not require manual handling by the staff, which reduces the workload and work intensity, thereby improving the welding processing efficiency of the tobacco heat exchanger.

[0035] When the first welding process of the tobacco heat exchanger is completed, the first cylinder 42 drives the steering seat plate 43 to move downward, and the steering placement plate 48 places the tobacco heat exchanger on the conveying wheel assembly 2, and the tobacco heat exchanger continues to be conveyed by the conveying wheel assembly 2, and is conveyed to the flipping assembly 6 for flipping.

[0036] like Figure 4 As shown, a flip assembly 6 for flipping the heat exchanger is provided in the middle of the main frame 1, and the specific flipping steps are as follows:

[0037] Step 1: When the tobacco heat exchanger moves to between the two groups of flip brackets 61 under the action of the conveying wheel assembly 2 and stops moving, the second cylinder 63 provided on the top plate 62 drives the clamping flip mechanism 64 to move downward;

[0038] Step 2: The clamping and flipping mechanism 64 moves downward to the middle of the tobacco heat exchanger, and the third cylinder 646 on the first support 643 drives the two sets of second connecting rods 648 to rotate through the second support 647. The second connecting rods 648 drive the two sets of first connecting rods 644 to rotate inward through the third support 649, and the two sides of the tobacco heat exchanger are clamped by the clamping blocks 645 provided on the first connecting rods 644;

[0039] Step three: After the clamping block 645 clamps the tobacco heat exchanger, the second cylinder 63 drives the clamping and flipping mechanism 64 and the tobacco heat exchanger to move upward, and then the third motor 642 on the mounting seat 641 drives the first support 643 to rotate to flip the tobacco heat exchanger. After the tobacco heat exchanger is flipped 180 degrees, it is placed back on the conveying wheel assembly 2. Then the clamping and flipping mechanism 64 releases the clamping of the tobacco heat exchanger and resets upward under the action of the second cylinder 63. The conveying wheel assembly 2 drives the tobacco heat exchanger to continue to move forward and enter the next processing step.

[0040] like Figure 5 As shown, during the clamping and flipping process of the tobacco heat exchanger, a fourth cylinder 65 is also installed on the second support 647. The fourth cylinder 65 is installed with a suction cup assembly 67 through a mounting plate 66. The suction cup assembly 67 is used to adsorb and clamp the heat exchanger to ensure that the heat exchanger remains stable when flipped.

[0041] The suction cup assembly 67 mainly includes a suction cup body 671 and a U-shaped frame 673, wherein the U-shaped frame 673 is fixedly connected to the mounting plate 66, an air nozzle 672 is arranged on the suction cup body 671, the suction cup body 671 is connected to the U-shaped frame 673 through a connecting rod 674, a plug 676 is fixedly arranged on the upper end of the connecting rod 674, a spring 675 is mounted on the outer periphery of the connecting rod 674 to ensure the adsorption effect of the suction cup body 671 on the tobacco heat exchanger.

[0042] A second steering assembly 5 for steering the heat exchanger is disposed at the other end of the main frame 1 . The structure and working steps of the second steering assembly 5 are the same as those of the first steering assembly 4 .

[0043] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
