Therefore, they should not be construed as limitations on the embodiments of this application.

[0030] In order to better understand the above-mentioned objectives, technical solutions and advantages of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings, so as to understand in detail how to solve the problems raised in the background art.

[0031] It should be noted that the material frame structure in this embodiment can be the material frame disclosed in the patent: Automatic Width Adjustment Mechanism and Adjustment Device for Material Frame (Application No.: 202111251397.8). This material frame has two fixed and movable limit frames respectively. By adjusting the movable limit frame, the distance between the two limit frames can be changed, thereby realizing the width adjustment of the material frame. This has been described in detail in the existing patent, and will not be repeated here.

[0032] like Figures 1 to 3 As shown, a material frame rapid width adjustment mechanism includes: a feeding unit 1 for transporting the material frame, the feeding unit 1 including a conveyor belt 11 and monitoring components 12 and fixing components 13 disposed on both sides of the conveyor belt 11; and an adjustment unit 2 for adjusting the width of the material frame, the adjustment unit 2 including a movable plate 21 and a first fixing plate 22 and a second fixing plate 23 disposed on both sides of the movable plate 21, the second fixing plate 23 having a pushing member 27 slidably disposed at its upper and lower ends, and the pushing member 27 being fitted with an adjustment member 28; wherein, the adjustment unit 2 is disposed on one side of the feeding unit 1, and the pushing member 27 is connected to the movable plate 21 so that the movable plate 21 drives the pushing member 27 and the adjustment member 28 to move back and forth.

[0033] Specifically, including but not limited to, the conveyor belt 11 can be equipped with a double-speed chain to meet the requirements of high-speed transmission and high load capacity. When the material frame flows into the designated position along the double-speed chain, the monitoring component 12 first detects the placement of the material frame. At this time, the opening of the material frame faces the opposite direction of the conveyor belt 11's forward direction. Then, the fixing component 13 can clamp the bottom edge of the material frame, thereby achieving precise positioning and fixing of the material frame. Then, the adjusting unit 2 is set on one side of the conveyor belt 11 corresponding to the material frame. The movable plate 21 of the adjusting unit 2 moves along the direction from the first fixing plate 22 to the second fixing plate 23, and drives the limiting component 25 and the pushing component 27 forward. When the adjusting component 28 is activated, the upper and lower adjusting components 28 abut against the two ends of the movable limiting frame in the material frame, thereby adjusting the distance between the two limiting frames and making the width of each cavity inside the frame consistent. Finally, the movable plate 21 of the adjusting unit 2 retracts, the fixing component 13 releases the material frame, and the material frame flows out with the conveyor belt 11. Repeating the operation allows for quick adjustment of the width of the material frame. It should be noted that the adjusting component 28 is detachably installed on the pushing component 27, and the front end of the adjusting component 28 can be adjusted to be flush with or protrude from the pushing component 27. When the two are flush, the pushing component 27 can fit against the side plate of the material frame, thereby cooperating with the adjusting component 28 to achieve the width adjustment of the material frame.
