[0002] The automatic paper feeding clamping device is an automated feeding equipment used by robotic arms. It is mainly used for gripping, handling, and positioning paper stacks and is widely used in industries such as printing, packaging, and logistics. Traditional clamps usually only use two side clamps to hold the paper stack, which has obvious defects in actual use: due to the lack of front-end protection, the paper stack is prone to scattering and shifting at the front end due to uneven force or vibration during the clamping process, affecting the feeding accuracy and stability; at the same time, relying solely on the two side clamps is difficult to effectively restrain the corners at the front end of the paper stack, further increasing the risk of shifting, leading to problems such as misalignment or dropping when the robotic arm grips it, reducing production efficiency and finished product quality. Utility Model Content

[0003] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide an automatic paper feeding fixture device. This device solves the problems of the paper stack front end being unprotected and easily shifting and scattered due to the use of only two side clamps in the existing equipment, as well as the problem of insufficient corner constraint affecting feeding accuracy and stability.

[0004] This utility model also provides an automatic paper feeding clamp device as described above, comprising: a driving assembly, with connecting frames one on both sides of the driving assembly, a clamping plate connected to the lower surface of the connecting frame one via an adjusting assembly one, a connecting frame two fixedly connected to the lower surface of the driving assembly, a front guard plate connected to the lower surface of the connecting frame two via an adjusting assembly two, side guard plates slidably connected to both sides of the front guard plate via transverse sliding rods, the side guard plates being L-shaped, and a longitudinal sliding rod fixedly connected to the rear surface of the side guard plates, the longitudinal sliding rod penetrating and slidably connected inside the clamping plate.

[0005] According to the present invention, an automatic paper feeding clamping device is provided, wherein the transverse slide bar is slidably connected inside the front guard plate, the clamping plate drives the side guard plate to move left and right through the longitudinal slide bar, and the front guard plate drives the transverse slide bar to drive the side guard plate to move back and forth.

[0006] According to the present invention, an automatic paper feeding clamping device includes a driving assembly comprising a cylinder and piston rods.

[0019] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0020] Reference Figures 1-4 This utility model provides an automatic paper feeding fixture device, which includes: a driving component, with connecting frames 8 on both sides of the driving component, a clamping plate 14 connected to the lower surface of the connecting frame 8 via an adjusting component, and a connecting frame 1 fixedly connected to the lower surface of the driving component.

[0021] Considering that traditional equipment only clamps from both sides and cannot restrain the front end and corners of the paper stack, causing the front end or corners of the paper to easily shift during feeding, the lower surface of the connecting frame 2 1 is connected to the front guard plate 5 through the adjusting component 2. Both sides of the front guard plate 5 are slidably connected to the side guard plates 6 through the transverse slide rods 4. The side guard plates 6 are L-shaped, and the rear surface of the side guard plates 6 is fixedly connected to the longitudinal slide rods 7. The longitudinal slide rods 7 slide through and are slidably connected inside the clamping plate 14. The front guard plate 5 can prevent the front end of the paper stack from being scattered, improving the neatness and stability of feeding. The side guard plates 6 simultaneously restrain the sides and front corners of the paper stack, preventing forward / backward / left / right displacement during clamping and improving feeding accuracy.

[0022] In summary, the improvement of this embodiment lies in:

[0023] The front guard plate 5 forms a "baffle" in front of the paper stack, effectively preventing the front end of the paper from shifting or scattering during clamping, thus improving the neatness and stability of the feeding. The L-shaped side guard plates 6 form a "baffle" at the two corners in front of the paper stack, which can simultaneously constrain the sides and front end of the paper stack. Together with the front guard plate 5, they form a comprehensive "enclosure" structure, thereby effectively preventing the paper stack from shifting forward or backward or left or right during clamping, thus improving the feeding accuracy.

[0024] Based on the above, other structures also need to be disclosed in detail, such as:

[0025] Reference Figure 1 Considering the need to adapt to paper stacks of different lengths, and the problem that fixed guard plates cannot adjust their front and rear positions, a transverse slide bar 4 is slidably connected inside the front guard plate 5. The clamping plate 14 drives the side guard plate 6 to move left and right through the longitudinal slide bar 7. The front guard plate 5 drives the transverse slide bar 4 to drive the side guard plate 6 to move back and forth. Through the transverse slide bar 4 and the longitudinal slide bar 7, the front, rear, left and right positions of the side guard plate 6 can be adjusted to adapt to paper stacks of different lengths and enhance versatility.

[0026] Reference Figure 2Considering the issue of driving the opening and closing of the gripper and supporting the overall structure, the drive assembly includes: cylinder 11 and piston rod 9. There are two piston rods 9, which are slidably connected inside the cylinder 11. Connecting bracket 1 8 is fixedly connected to the other end of the piston rod 9, and connecting bracket 2 1 is fixedly connected to the lower surface of the cylinder 11, so as to realize the stable drive of the opening and closing action of the gripper and provide the installation base for the front guard plate, side guard plate and other protective structures.

[0027] Reference Figure 2 Considering the need to adjust the position of the clamping plate to accommodate paper stacks of different widths, the adjustment component includes: a slide groove 13 and a fixing bolt 12. The slide groove 13 is set on the connecting frame 8, and the fixing bolt 12 is slidably connected inside the slide groove 13. The clamping plate 14 is threadedly connected to the fixing bolt 12. The spacing of the clamping plate 14 can be quickly adjusted by sliding the fixing bolt 12. After adjustment, the fixing bolt 12 can be tightened to fix the position, adapting to paper stacks of different widths, and the operation is convenient and efficient.

[0028] Reference Figure 1 Considering the need to adjust the position of the front guard plate to match the front position of the paper stack and ensure the effectiveness of protection, the adjustment component two includes: slide groove two 3 and fixing bolt two 2. The slide groove two 3 is set on the connecting frame two 1, and the fixing bolt two 2 is slidably connected inside the slide groove two 3. The front guard plate 5 is threadedly connected to the fixing bolt two 2. The position of the front guard plate 5 can be flexibly adjusted by sliding the fixing bolt two 2. After the adjustment is completed, the fixing bolt two 2 can be tightened to fix the position, accurately protect the front of the paper stack and prevent it from shifting and scattering.

[0029] Reference Figure 2 Considering the need to fix the cylinder and ensure its stability when connected to the robotic arm, a fixing flange 10 is fixedly connected to the upper surface of the cylinder 11. The fixing flange 10 achieves a firm connection between the cylinder and the robotic arm, preventing loosening or displacement and improving overall reliability.

[0030] Working principle: In the initial stage, pre-adjustment is made according to the paper stack size - the fixing bolt 12 of the sliding adjustment component 1 (located in the slide groove 13 of the connecting frame 8) is adjusted to match the width of the paper stack. After completion, the fixing bolt 12 is locked.

[0031] At the same time, the fixing bolt 2 of the sliding adjustment component 2 (located in the slide groove 3 of the connecting frame 2 1) adjusts the position of the front guard plate 5 to match the front end of the paper stack, and locks the fixing bolt 2. During the adjustment of the front guard plate 5, the side guard plate 6 will move synchronously under the action of the transverse slide bar 4.

[0032] After adjustment, cylinder 11 drives two piston rods 9 to extend synchronously, causing connecting frame 8 to open left and right, and clamping plate 14 to open and clamp the two sides of the paper stack.

[0033] At the same time, the connecting frame 2 1 and the front guard plate 5 move down to the front end of the paper stack. The L-shaped side guard plate 6 is driven by the clamping plate 14 through the longitudinal slide rod 7 to open synchronously to the left and right. Finally, the front guard plate 5 blocks the front end of the paper stack, and the side guard plate 6 constrains the two sides and corners to form an "enclosure structure". Then, the cylinder 11 drives the clamping plate 14 to move and drives the side guard plate 6 to move inward synchronously through the longitudinal slide rod 7 to clamp the paper stack.

[0034] After clamping, the robotic arm drives the clamp to move to the target position. During the movement, the front guard plate 5 prevents the front end of the paper stack from scattering, and the side guard plate 6 suppresses left and right and corner deviations to ensure the stability of the paper stack. After reaching the target position, the cylinder 11 drives the clamping plate 14 to release the two sides of the paper stack, completing the feeding.

[0035] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
