Description

Technical Field

[0001] The utility model relates to the technical field of doors, in particular to an automatic feeding and stretching machine. Background Art

[0002] In the traditional production process of door embossing, a lot of manpower is usually required, including material handling, embossing pattern positioning, embossing process monitoring, and finished product collection. These links are not only labor-intensive, but also inefficient and easily affected by human factors, resulting in unstable product quality. With the development of industrial automation technology, automated production lines have gradually become a development trend in the manufacturing industry, but in the field of door embossing, the application of fully automatic production lines is still relatively limited.

[0003] Existing door embossing production lines mostly use semi-automatic or manual operation methods, with a low degree of automation, and some key links still require manual intervention. Due to reliance on manual operation, the production speed is limited, it is difficult to meet the needs of large-scale production, and the production efficiency is low. The inconsistency of manual operation may cause fluctuations in product quality, affect product consistency, and make quality control difficult. There are certain safety risks in the manual operation process, especially in the handling of heavy objects and the operation of mechanical equipment, which poses safety problems. In addition, the maintenance cost is high, and the complex mechanical structure is prone to failure. In the door embossing production line, embossing is the core process, so it is necessary to improve the above problems and develop an automatic feeding and stretching machine for the embossing process.

[0060] Figure 1-3 To show the automatic feeding stretching machine more clearly, the ground is removed. The concave and convex spatial positions of the ground refer to the position of the track.

[0061] like Figure 1-2 As shown, the loading and unloading suction cup assembly 832 moves left and right on the loading trailer bracket 831, and the stacked steel materials are loaded one by one onto the feeding platform 84 by suction.
