Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features.

[0039] See also Figures 1 to 6 As shown, the utility model is an adaptive cloth clamping mechanism 100, and the adaptive cloth clamping mechanism 100 includes an upper mounting member 1, a lower mounting member 2, an upper clamping jaw 3, a lower clamping jaw 4 and an elastic abutting member 5;

[0040] The lower clamping jaw 4 is fixedly connected to the lower mounting member 2 to support the lower clamping jaw 4; the upper mounting member 1 is provided with an upper jaw mounting portion 11 at a position corresponding to the lower clamping jaw 4, and the upper clamping jaw 3 is arranged above the upper jaw mounting portion 11, and one end of the upper clamping jaw 3 is movably connected to the upper jaw mounting portion 11 so that the upper clamping jaw 3 can move; the elastic supporting member 5 is arranged above the upper clamping jaw 3, and the middle part of the upper clamping jaw 3 is pressed against the upper jaw mounting portion 11 by the elastic supporting member 5; the other end of the upper clamping jaw 3 has a clamping portion 31 extending downward to the top of the lower clamping jaw 4, so that the fabric can be clamped by the cooperation of the clamping portion 31 and the lower clamping jaw 4.

[0041] The utility model adopts the method of fixedly connecting the lower clamping jaw 4 with the lower mounting member 2, movably connecting one end of the upper clamping jaw 3 with the upper jaw mounting portion 11 of the upper mounting member 1, and pressing the middle part of the upper clamping jaw 3 against the upper jaw mounting portion 11 through the elastic push-up member 5. At the same time, the other end of the upper clamping jaw 3 is designed to have a clamping portion 31 extending to the upper part of the lower clamping jaw 4 and cooperating with the lower clamping jaw 4; so that in the specific process of clamping and pulling the fabric, the upper clamping jaw 3 can float up and down under the elastic force of the elastic push-up member 5, and realize adaptive adjustment of the clamping degree of the fabric, thereby effectively preventing the fabric from being damaged due to clamping too tightly; when it is necessary to clamp and pull multiple rolls of fabric at the same time, the upper clamping jaw 3 can also be adaptively adjusted under the elastic force of the elastic push-up member 5, thereby being able to well meet the needs of clamping and pulling multiple layers of fabric at the same time, and ensuring that the fabric will not be clamped and damaged.

[0042] In some embodiments of the present invention, in order to ensure that the upper clamping jaw 3 can float up and down during use, please refer to Figure 2 As shown, the elastic abutment 5 includes a spring 51 and a limiting column 52; the lower end of the limiting column 52 is connected to the upper jaw mounting portion 11, and the upper end of the limiting column 52 is provided with a limiting portion 53, so as to limit the upper end of the spring 51 by utilizing the limiting portion 53, and a movable through hole 32 is opened in the middle part of the upper clamping jaw 3, and the limiting column 52 passes through the movable through hole 32, and the movable through hole 32 is used to ensure that the upper clamping jaw 3 can float up and down smoothly without being affected by the limiting column 52; the spring 51 is sleeved on the limiting column 52, and the upper end of the spring 51 abuts on the limiting portion 53, and the lower end of the spring 51 abuts on the upper surface of the upper clamping jaw 3.

[0043] As a specific implementation of the utility model, the limiting column 52 is a bolt, a nut 54 is arranged on the bolt, and the limiting portion 53 is formed on the nut 54. In the specific implementation of the utility model, a threaded hole 111 is opened on the upper claw mounting portion 11, and the lower end of the bolt is screwed into the threaded hole 111.

[0044] Since different fabrics or fabrics with different numbers of layers of clamping and pulling require different clamping degrees, the utility model adopts a bolt as a limiting column 52, and equips the bolt with a nut 54, and forms a limiting portion 53 on the nut 54, so that in specific use, the compression amount of the spring 51 can be adjusted by rotating the nut 54, and then the clamping degree can be adjusted to better meet the use requirements of various clamping and pulling occasions; at the same time, by using the nut 54 to adjust the compression amount of the spring 51, there is no need to rotate and adjust the bolt, which can avoid the lower end of the bolt from affecting the clamped fabric.

[0045] More specifically, the movable through hole 32 is a strip-shaped through hole extending along the length direction of the upper clamping jaw 3 , thereby further ensuring that the upper clamping jaw 3 can float up and down smoothly.

[0046] As a specific implementation of the utility model, the clamping portion 31 is an arc-shaped hook plate structure, and the lower clamping jaw 4 is a strip plate structure. The utility model designs the clamping portion 31 to be an arc-shaped hook plate structure, and designs the lower clamping jaw 4 to be a strip plate structure, so that the contact area between the fabric and the clamping portion 31 and the lower clamping jaw 4 can be increased, and the fabric can be reliably clamped without damaging the fabric.

[0047] In some embodiments of the utility model, the middle part of the upper jaw 3 has a first bonding plate 33, and the free end of the upper jaw mounting portion 11 is provided with a second bonding plate 112. When the upper jaw 3 and the lower jaw 4 are in an open state, the lower surface of the first bonding plate 33 is bonded to the upper surface of the second bonding plate 112, which not only makes the entire structure more compact, but also ensures the stability of the upper jaw 3.

[0048] In some embodiments of the utility model, the upper mounting member 1 includes a drive shaft 12 and a mounting plate 13, the mounting plate 13 is connected to the drive shaft 12, and specifically, the mounting plate 13 can be detachably connected to the drive shaft 12 by screws; the connecting end of the upper jaw mounting portion 11 is provided with a first inclined plate 113, the first inclined plate 113 is inclined outward from top to bottom, and a plug-in through hole 114 is provided through the first inclined plate 113 to realize a movable connection with one end of the upper clamping jaw 3 by using the plug-in through hole 114; when the present invention is implemented, each of the first inclined plates 113 can be connected together to form a whole to improve strength;

[0049] The upper clamping jaw 3 is formed with a second inclined plate 34. When the upper clamping jaw 3 and the lower clamping jaw 4 are in the open state, the lower surface of the second inclined plate 34 fits with the upper surface of the first inclined plate 113, so that the whole structure can be more compact and the stability of the upper clamping jaw 3 is ensured; the end of the second inclined plate 34 is provided with a plug-in plate 35, and the plug-in plate 35 passes through the plug-in through hole 114.

[0050] When the utility model is implemented, the driving shaft 12 needs to be connected to a driving mechanism 6. When working, the driving shaft 12 is driven to rotate a certain angle by the driving mechanism 6, and the driving shaft 12 will drive the mounting plate 13 to rotate together. Since the upper clamp 3 is installed on the mounting plate 13, the mounting plate 13 can drive the clamping part 31 of the upper clamp 3 to approach the lower clamp 4 and realize the fabric clamping function when rotating with the driving shaft 12; and when the fabric needs to be loosened, the driving shaft 12 is driven to rotate in the opposite direction by a certain angle by the driving mechanism 6, so that the driving shaft 12 drives the clamping part 31 of the upper clamp 3 away from the lower clamp 4.

[0051] More specifically, the upper mounting member 1, the lower mounting member 2, the upper clamping jaw 3 and the lower clamping jaw 4 can all be made of steel (such as stainless steel); an arc-shaped narrowing portion 351 is formed at the connection between the plug-in piece 35 and the second inclined plate 34, and the length of the plug-in hole 114 is slightly smaller than the width of the plug-in piece 35. Since the plug-in piece 35 has a certain elastic deformation ability, it can pass through the plug-in hole 114 under the action of external force. At the same time, the thickness of the plug-in piece 35 is slightly smaller than the width of the plug-in hole 114. This ensures that the plug-in piece 35 is not easily separated from the first inclined plate 113 after passing through the plug-in hole 114, and also ensures that the upper clamping jaw 3 can flexibly float up and down.

[0052] More specifically, the mounting plate 13 and the upper claw mounting portion 11 are integrally formed, which is more convenient to manufacture and can also ensure the connection strength between the upper claw mounting portion 11 and the mounting plate 13 .

[0053] In some embodiments of the utility model, the lower mounting member 2 includes a fixed shaft 21 and a fixed plate 22, and the fixed plate 22 is connected to the fixed shaft 21. Specifically, the fixed plate 22 can be detachably connected to the fixed shaft 21 by screws; the lower clamping jaw 4 and the fixed plate 22 are integrally formed, which is convenient for manufacturing and can ensure the connection strength between the lower clamping jaw 4 and the fixed plate 22.

[0054] In some embodiments of the utility model, the lower mounting member 2 is provided with a plurality of lower clamping jaws 4 at equal intervals along the length direction, and the upper mounting member 1 is provided with an upper clamping jaw 3 corresponding to each lower clamping jaw 4, so that the fabric can be clamped better through the mutual cooperation of each lower clamping jaw 4 and each upper clamping jaw 3.

[0055] When the adaptive cloth clamping mechanism 100 of the present invention is used in a specific application, please refer to Figure 6 As shown, the adaptive cloth clamping mechanism 100 can be applied to the clamping and pulling main machine 200 of the cloth spreading machine, so that the clamping and pulling main machine 200 can use the adaptive cloth clamping mechanism 100 to clamp the fabric and pull the fabric to achieve cloth spreading.

[0056] Although the specific implementation methods of the present invention are described above, those skilled in the art should understand that the specific embodiments described are only illustrative and are not intended to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included in the scope of protection of the claims of the present invention.
