The workbench 1 includes an operation table surface 13, and a limiting groove 131 is opened on the operation table surface 13. The limiting groove 131 is used to guide the moving track of the limiting assembly 3;

[0033] The driving assembly 2 includes a transmission lead screw 23, a clamping slider 25 is installed on the transmission lead screw 23 in a threaded manner, and the clamping slider 25 is clamped and installed with the limiting assembly 3;

[0034] The limiting assembly 3 includes a fixed stop frame 31, a connecting frame 32 is installed on the fixed stop frame 31, a connecting seat 33 is slidably installed on the connecting frame 32, and a movable stop frame 34 is rotatably installed on one side of the connecting seat 33;

[0036] Specifically, by providing the movable stop frame 34 rotatably installed on the connecting seat 33 and the connecting seat 33 slidably installed on the connecting frame 32, the movable stop frame 34 can slide horizontally along the connecting frame 32 and rotate around the connecting seat 33, and cooperate with the fixed stop frame 31 to form a dynamically adjustable clamping space, achieving the effects of adaptively adjusting the clamping distance according to the cardboard size and evenly distributing the clamping force, and avoiding the material deviation caused by uneven force in traditional rigid clamping;

[0037] By opening the limiting groove 131 on the operation table surface 13 and providing the limiting frame 342 at the bottom of the movable stop frame 34 that is slidably matched with the limiting groove 131, and at the same time keeping the movable stop frame 34 and the fixed stop frame 31 in a parallel clamping state, a multi-dimensional limiting system of "horizontal trajectory constraint + vertical symmetric clamping + vertical support" is constructed, achieving the effects of forcibly standardizing the material conveying trajectory, offsetting the lateral force deviation, and preventing the cardboard from warping or shaking, and solving the problem of unstable conveying caused by single-dimensional limiting and single clamping method in the existing feeding mechanism from the structural design.

[0038] Embodiment 2: In order to achieve stable driving of the limiting assembly and accurately guide its moving track, as Figure 1and Figure 2 As shown in Figure 2 , in this embodiment, the workbench 1 includes a first frame 11, a second frame 12 and an operating tabletop 13. The first frame 11 and the second frame 12 are respectively fixedly installed on both sides of the operating tabletop 13. A limiting groove 131 for guiding the moving track of the limiting component 3 is formed on the operating tabletop 13; a reserved groove 121 for the fixed stop 31 to move is reserved on the second frame 12.

[0039] The driving component 2 includes a DC motor 21, a first mounting bracket 22, a transmission lead screw 23, a first guide rail 24, a clamping slider 25 and a second mounting bracket 26. The first mounting bracket 22 and the second mounting bracket 26 are both fixed to the second frame 12. The DC motor 21 on the first mounting bracket 22 is in transmission connection with the transmission lead screw 23. The two ends of the transmission lead screw 23 are respectively in rotational cooperation with the first mounting bracket 22 and the second mounting bracket 26; a first guide rail 24 connected to the second frame 12 is fixedly arranged on the outer side of the transmission lead screw 23. The first guide rail 24 cooperates with the clamping slider 25 threadedly installed on the transmission lead screw 23 to realize the clamping installation with the limiting component 3.

[0040] A second guide rail 27 is fixedly installed on the clamping slider 25. The bottom of the fixed stop 31 in the limiting component 3 is slidably installed with the second guide rail 27 through a first sliding frame 311 and a connecting seat 33 through a second sliding frame 332 at the bottom, so as to realize the connection between the clamping slider 25 and the limiting component 3.

[0041] The DC motor 21 drives the transmission lead screw 23 to rotate, driving the clamping slider 25 to linearly slide along the first guide rail 24, providing a stable driving force for the limiting component 3; the limiting groove 131 on the operating tabletop 13 is slidably matched with the limiting frame 342 at the bottom of the movable stop 34, and the reserved groove 121 on the second frame 12 limits the movement of the fixed stop 31, restricting the movement track of the limiting component 3 from both the driving end and the guiding end, solving the problem of conveying deviation caused by unstable driving or lack of guiding in the traditional feeding mechanism, ensuring that the limiting component 3 moves precisely along the preset path, and laying a foundation for stably clamping the cardboard subsequently.

[0042] Embodiment 3: In order to realize the adaptive clamping and multi-dimensional limiting support for cardboard of different sizes, such as Figure 3 and Figure 4As shown in the figure, in this embodiment, the limit assembly 3 includes a fixed stop frame 31, a connecting frame 32, a connecting seat 33 and a movable stop frame 34. The bottom of the fixed stop frame 31 is slidably connected to the second guide rail 27 on the clamping slider 25 through the first sliding frame 311; the connecting frame 32 is fixed to the upper part of the fixed stop frame 31, and is drivingly connected to the slidably mounted connecting seat 33 through the adjusting cylinder 321 and the positioning frame 322; a movable stop frame 34 parallel to the fixed stop frame 31 is rotatably mounted on one side of the connecting seat 33. The limit frame 342 at the bottom of the movable stop frame 34 is slidably matched with the limit groove 131 on the operation table 13, and the handle 341 provided on the outside thereof is used to manually adjust the rotation angle of the movable stop frame 34; a chute 271 is provided on the second guide rail 27 on the clamping slider 25, and the connecting seat 33 passes through the chute 271 through the limit slider 331 to realize the sliding guide along the second guide rail 27, and the second sliding frame 332 at the bottom of the connecting seat 33 is height-matched with the first sliding frame 311 of the fixed stop frame 31, and is jointly slidably connected to the second guide rail 27.

[0043] The adjusting cylinder 321 drives the connecting seat 33 to slide along the connecting frame 32 through the positioning frame 322. Combined with the handle 341, the movable stop frame 34 is rotated and adjusted around the connecting seat 33, and the clamping distance between the fixed stop frame 31 and the movable stop frame 34 is accurately adjusted to adapt to cardboard of different widths; the second sliding frame 332 and the first sliding frame 311 slide synchronously on the second guide rail 27 to ensure balanced force when the double stop frames are clamped in parallel. With the vertical support of the limit groove 131 for the limit frame 342, a composite limit mechanism of "adjustable horizontal distance - symmetric vertical clamping force - rigid trajectory constraint" is formed. This mechanism solves the problem of unstable conveying caused by the single clamping method of the traditional feeding mechanism and the inability to adapt to the change of material size, realizes the accurate clamping and stable conveying of diversified cardboard, and ensures the accuracy of the subsequent label removing process.

[0044] When the utility model is in use, the movable stop frame 34 is rotated through the handle 341, and the stacked cardboard is placed on the operation table 13.

[0045] The adjusting cylinder 321 is started, and the connecting seat 33 is driven to slide along the connecting frame 32 through the positioning frame 322. During this process, the limit frame 342 at the bottom of the movable stop frame 34 slides along the limit groove 131 on the operation table 13, so that the movable stop frame 34 moves horizontally, pushing the stacked cardboard to ensure that the stacked cardboard is located on the opposite side of the fixed stop frame 31 and the movable stop frame 34.

[0046] The DC motor 21 is turned on, the motor drives the transmission lead screw 23 to rotate, the clamping slider 25 slides linearly along the transmission lead screw 23, and at the same time drives the limit assembly 3 to move through the second guide rail 27. The fixed stop frame 31 enters the reserved groove 121 of the second frame 12, so as to ensure the stable movement of the limit assembly 3 along the preset trajectory. Ensure the parallelism of the double stop frames, and cooperate with the support of the limit groove 131 for the limit frame 342 to prevent the cardboard from shifting and warping.

[0047] Observe the cardboard conveying effect and confirm that it smoothly enters the subsequent label removal process. If it is necessary to change the cardboard specifications, repeat the above steps to readjust the clamping distance and driving parameters to ensure that the material conveying mechanism always adapts to the conveying requirements of different materials.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
