Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0025] The present invention will now be described in detail with reference to the accompanying drawings. Figures 1 to 3 As shown.

[0026] Example 1: A material conveying mechanism includes: a left vertical plate 13 and a right vertical plate 5 arranged parallel to each other at intervals. Both the left and right vertical plates 5 have belt drive mechanisms on their inner surfaces. The lower end of the left vertical plate is connected to a left support leg 12, and the lower end of the right vertical plate 5 is connected to a right support leg 8. At least one of the left support leg 12 and the right support leg 8 is a movable support leg. The lower end of the movable support leg is connected to a slider 7 and a linear module that drives the slider 7 to move. The direction of movement of the slider 7 is perpendicular to the length direction of the left vertical plate 13. The belt drive mechanism includes a belt 2, which has an upper belt section parallel to the length direction of the left vertical plate 13. When conveying materials, both ends of the materials overlap the upper belt sections of the two belts 2.

[0027] In this technical solution, both the left support leg 12 and the right support leg 8 can be movable support legs, or one can be a fixed support leg and the other a movable support leg. In this embodiment, the left support leg 12 is a fixed support leg and the right support leg 8 is a movable support leg. The fixed support leg is longer than the movable support leg and is fixed to the fixed platform. The linear module is also fixed to the worktable. When the steel sheet 100 is conveyed, it is transported between the left vertical plate and the right vertical plate 5 and overlaps with the belt 2 of the belt drive mechanism on both sides. When the belt drive mechanism is working, it pulls the material forward through the upper belt section of the belt 2, thereby completing the material conveying. Secondly, since the movable support leg is connected to the slider 7, when the distance between two adjacent upper belt ends needs to be adjusted in the direction perpendicular to the length of the left vertical plate, the slider and the movable support leg can be moved by moving the linear module, thereby adjusting the distance between the belt drive mechanisms on both sides to accommodate steel sheets 100 of various widths. Secondly, to facilitate the connection between the movable support leg and the slider, a base block 21 is connected to the lower end of the movable support leg, and the base block 21 is fixedly connected to the slider. Setting up base block 21 can increase the connection area with the slider, making it easier to fix.

[0028] Furthermore, the linear module includes a slide rail 6 connected to the slider, and the slider and the slide rail 6 are slidably connected; the linear module also includes a nut seat 9 disposed on the movable support leg, the nut seat 9 is connected to a lead screw 10, and one end of the lead screw 10 is connected to a rotary drive mechanism for driving the lead screw 10 to rotate.

[0029] This technical solution indirectly drives the slider by moving the movable support leg, which in turn moves the slider. By setting a slide rail 6, the slider moves linearly along the slide rail 6, maintaining the directionality of the movable support leg's movement. Furthermore, the screw-nut mechanism formed by the nut seat 9 and the lead screw 10 allows for adjustment of the movable support leg's movement, ensuring accuracy. Additionally, the linear module can be a linear motor. Using a linear motor for the linear module results in a simple overall structure and convenient operation. The slider is directly driven by the linear motor.

[0030] See Figure 1 The left support leg 12 is a fixed support leg, and the right support leg 8 is a movable support leg. The fixed support leg is connected to a bearing that cooperates with the lead screw 10. One end of the lead screw 10 is inserted into the bearing and sleeved with the bearing.

[0031] Connecting one end of the lead screw 10 to the fixed support leg can prevent the lead screw 10 from shaking and maintain its stability.

[0032] See Figure 2 The rotary drive mechanism includes a drive motor 17, which is connected to the other end of the lead screw 10, or the drive motor 17 is connected to the other end of the lead screw 10 through a transmission mechanism 20.

[0033] See Figure 2 , Figure 3 The transmission mechanism 20 includes an active synchronous pulley connected to the shaft of the drive motor 17 and a driven synchronous pulley connected to the other end of the lead screw 10. The active synchronous pulley is connected to the driven synchronous pulley via a synchronous belt.

[0034] When the lead screw 10 rotates, it can be directly driven by the drive motor 17. At this time, the shaft of the drive motor 17 can be connected to the other end of the lead screw 10 via a coupling, allowing the drive motor 17 to directly drive the lead screw 10 to rotate. Considering the device size and available space, a transmission mechanism 20 can be provided between the drive motor 17 and the lead screw 10. The transmission mechanism 20 can be a gear transmission mechanism, etc. In this embodiment, a synchronous belt transmission mechanism is selected for the transmission mechanism 20. This allows adjustment of the distance between the drive motor 17 and the lead screw 10, and control of the rotation angle of the lead screw 10. In a specific configuration: the other end of the lead screw 10 is connected to a support block via a bearing seat, the drive motor 17 is connected to a support plate, and a fixing plate is connected to the lower end of the support plate. The fixing plate has multiple adjustment slots. By setting these adjustment slots to adjust the installation position of the drive motor 17, the tension of the synchronous belt can be adjusted.

[0035] See Figure 1 , Figure 2 The belt drive mechanism includes upper main pulleys 1 located on both sides above. The lower ends of the left vertical plate and the right vertical plate 5 are connected to connecting plates 18. The connecting plates 18 are connected to a drive motor 11. The drive motor 11 is connected to a drive pulley 15. The left vertical plate and the right vertical plate 5 are each connected to two belt adjusting wheels 16. The two belt adjusting wheels 16 are located above the drive motor 11, and the distance between the two belt adjusting wheels 16 is smaller than the diameter of the drive pulley 15.

[0036] By setting two upper main pulleys 1, an upper belt segment can be formed; the driving pulley 15 drives the two upper main pulleys 1 to rotate through the belt. The setting of two belt adjusting wheels 16 can increase the contact area between the belt and the driving pulley 15 and prevent the belt from slipping with the driving pulley 15.

[0037] Preferably, both the left vertical plate and the right vertical plate 5 are connected to a number of upper intermediate wheels 3, and the upper intermediate wheels 3 are located between the two upper main pulleys 1.

[0038] Adding an upper intermediate pulley 3 can prevent the belt from bending excessively when bearing the weight of the steel sheet 100.

[0039] See Figure 1 The left vertical plate and the right vertical plate 5 are each connected to several upper adjusting wheels 4. The upper adjusting wheels 4 are located between adjacent upper middle wheels 3 and below the upper middle wheels 3.

[0040] The upper adjusting wheel 4 can increase the contact area between the belt and the upper intermediate wheel 3, adjust the belt tension, and prevent the belt from separating from the intermediate pulley.

[0041] Furthermore, lower adjusting wheels 23 are connected to the lower ends of the left vertical plate and the right vertical plate 5 respectively, and the lower adjusting wheels 23 are located below the upper main pulley 1.

[0042] The lower adjusting pulley 23 is used to change the direction of the belt and adjust the contact area between the belt and the upper main pulley 1. This reduces the distance between two adjacent pulleys and prevents the belt span from being too long.

[0043] Furthermore, several L-shaped auxiliary pieces 22 are connected to the upper inner side of the left vertical plate and the right vertical plate 5. The vertical section of the L-shaped auxiliary piece 22 is fixedly connected to the left vertical plate or the right vertical plate 5. The horizontal section of the L-shaped auxiliary piece 22 is located below the upper belt section of the belt or abuts against the lower end face of the upper belt section.

[0044] When steel sheet 100 and other heavy objects are being transported, they will press the belt downwards, causing the belt to bend significantly and bear considerable pressure. To prevent damage to the belt, multiple L-shaped auxiliary plates 22 are installed. The L-shaped auxiliary plates 22 provide auxiliary support for the belt. Furthermore, during use, the surface of the horizontal section is smooth to reduce friction with the belt.

[0045] See Figure 1 , Figure 3 Limiting blocks 14 are connected to the upper ends of the left vertical plate and the right vertical plate 5.

[0046] After setting the limit block 14, the steel sheet 100 can be limited between the two limit blocks 14 to avoid misalignment.

[0047] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
