Description

Technical Field

[0001] The utility model relates to the technical field of tinplate can processing, in particular to a tin can welding device. Background Art

[0002] Tinplate cans are a common type of iron can. In the production process of tinplate cans, the tinplate can sheets need to be cut and manually bent into circles one by one, and then sent to a high-frequency welding machine to weld the seams of the tinplate can sheets together to form a cylinder.

[0003] When welding the gap of a tinplate can with existing welding equipment, in order to ensure that the tinplate can does not shake, a cylinder is generally used to fix the tinplate can with a clamping plate, and then welding is performed. However, the force applied by the clamping plate to clamp the tinplate can is inconvenient to control, resulting in the tinplate can being concave inward at the place where the clamping plate is clamped, making the tinplate can unable to be used normally. Utility Model Content

[0006] The effect achieved by the above components is: when the tinplate can needs to be welded, the tinplate can is first placed in the placement slot, the cylinder on the U-shaped frame is opened, and the cylinder brings the two splints closer to each other. At this time, one of the splints moves with the first tooth plate on the bracket, and the first tooth plate rotates with the first gear and the second gear, and the second gear plate moves with the two protective plates. The two protective plates are inserted into the interior of the tinplate can and fit with the inner wall of the tinplate can. At this time, the two splints squeeze the tinplate can to achieve the effect of fixing the tinplate can. Finally, the gap of the tinplate can is welded through the welding head on the welding machine, and the two protective plates set by the protective device are inserted into the inner wall of the tinplate can and the inner wall of the tinplate can is pressed against, thereby achieving the effect of protecting the tinplate can and avoiding the situation where the splint is too strong and the tinplate can is grooved inward.

[0017] Preferably, a telescopic rod is provided on one side of the two protective plates close to each other, and both ends of the telescopic rod are fixedly connected to the two protective plates.

[0018] The effect achieved by the above components is: by setting the telescopic rod, the moving direction of the protective plate is restricted, thereby preventing rotation between the two protective plates.

[0019] Preferably, a plurality of control blocks are fixedly connected to the arc surface of the threaded barrel, and the surfaces of the control blocks are provided with anti-slip grooves.

[0020] The effect achieved by the above components is: by setting the control block, the contact area between the staff's hand and the threaded barrel is increased, thereby making it easier for the staff to rotate the threaded barrel, bringing convenience to the staff.
