The working principle of the shaping weaving device is as follows:

when the straw bundling machine works, in the conveying process, when the quantitatively-divided straws are tightened and bundled, the conveying device conveys the bundled straw bundles to a fixed cavity of the middle shaping mechanism; under the drive of the material guide driving mechanism, the shaping roller starts to rotate, and then the straw bundle is pushed to move forwards along the shaping cavity. Wherein, because the size that the design chamber is on a parallel with the radial direction of design roller diminishes gradually, the distance between design roller and the spacing design board diminishes gradually promptly, under the promotion of guide block, the straw bundle passes the design chamber gradually, and at the in-process of moving forward along spacing design board, the thickness that the straw bundle is on a parallel with the radial direction of design roller diminishes gradually, until being equal to the width of design chamber to accomplish the design. In the process, the shaping roller transfers the straw bundles to the front of the weaving station from the conveying device, and simultaneously carries out progressive shaping on the straw bundles, namely, the straw bundles are gradually subjected to walking extrusion forming, so that on one hand, normal transfer work is not hindered, on the other hand, the gradual change process can prevent the bundling rope from being deformed or stretched and broken, shaping is guaranteed on the premise of bundling, and the straw with local protrusions can be extruded, so that the straw is more flat; after shaping, the thicknesses of all the straw bundles in at least one direction are kept consistent, and then the straw bundles can be used as the surface of the straw mat in a weaving station, so that the straw mat with better surface quality can be woven.

After shaping is finished, the material guide block pushes the shaped straw bundles away from the shaping cavity, at the same time or before, the transverse transfer mechanism drives the self-adaptive fixing mechanism to move towards the middle shaping mechanism, and the lifting transfer mechanism drives the self-adaptive fixing mechanism to move downwards for a certain distance so as to avoid the straw bundles to be delivered. When the fixed clamp moves to the lower part of the straw bundle, namely the movable clamp and the fixed clamp are respectively positioned at two sides right below the straw bundle, the movable clamp and the fixed clamp move upwards for a certain distance under the driving of the lifting transmission mechanism until the movable clamp and the fixed clamp are respectively positioned at two sides of the straw bundle; the fixed clamp is in an open state at the moment, the driving piece is loosened to act on the movable clamp, and the compression spring is in a compressed state; when the movable clamp and the fixed clamp move to the two sides of the straw bundle, the driving piece is loosened to cancel the acting force on the movable clamp, and the compression spring starts to recover and release potential energy, so that the movable clamp is driven to move towards the direction of the fixed clamp until the movable clamp is clamped on the straw bundle.

Through the structure, under the drive of the transverse driving motor 11e, the fixing clamp can move transversely to convey the straw bundles to the weaving station 19e, and under the drive of the lifting driving cylinder 13e, the fixing clamp can move vertically to avoid the straw bundles to be conveyed and the sewn straw bundles.

Referring to fig. 12-16, the movable clamp 1e comprises a movable clamping part 1-1e, a movable connecting part 1-2e and a sliding part 1-3 e; the movable connecting part 1-2e is arranged between the movable clamping part 1-1e and the sliding part 1-3e, and the extending direction of the movable connecting part is vertical to the conveying direction of the straw bundles; the movable clamping parts 1-1e are multiple and are uniformly arranged above the movable connecting parts 1-2 e; the sliding parts 1-3e are also provided with a plurality of sliding parts which are uniformly arranged below the movable connecting parts 1-2 e; the top plate 16e is provided with a plurality of sliding chutes 16-1e matched with the sliding parts 1-3e of the movable clamp 1e, and the extending direction of the sliding chutes 16-1e is parallel to the conveying direction of the straw bundles. Thus, under the driving of the self-adaptive driving mechanism, the movable clamp 1e can move transversely along the sliding groove 16-1e, so as to clamp or separate the straw bundle.

Referring to fig. 12 to 16, a fixing strip 17e is provided on a side of the movable clamp 1e away from the fixed clamp 2e, and the fixing strip 17e is fixedly provided on a top plate 16 e; the compression spring 4e is arranged in the sliding groove 16-1e, and two ends of the compression spring respectively abut against the fixed strip 17e and the sliding part 1-3e of the movable clamp 1 e.

The structure has the advantages that after the straw is sewn, the telescopic rod of the driving cylinder is loosened to move towards the direction far away from the fixed clamp 2e, and in the process, the fixed nut is propped against the fixed strip 17e, so that the movable clamp 1e is driven to be far away from the fixed clamp 2e, and the straw bundle is loosened; when the straw bundle is clamped to the requirement and conveyed to the weaving station 19e, the telescopic rod which loosens the driving cylinder moves a certain distance in the direction of the fixed clamp 2e rapidly, the fixed nut is far away from the movable clamp 1e, so that the extra resistance caused by the telescopic rod can be reduced, and the compression spring 4e can be conveniently compressed to perform self-adaptive recovery.

Referring to fig. 12 to 16, the fixed clamp 2e includes fixed clamping portions 2 to 1e and fixed connecting portions 2 to 2e, and the number of the fixed clamping portions 2 to 1e is equal to that of the movable clamping portions 1 to 1e, and the fixed clamping portions are uniformly arranged above the fixed connecting portions 2 to 2 e. And the fixed clamping part 2-1e of the fixed clamp 2e is provided with a bearing part 2-3e which transversely extends towards the movable clamp 1e, and the movable clamping part 1-1e of the movable clamp 1e is provided with an avoidance bearing hole for avoiding the bearing part 2-3 e. In the process of conveying the straw bundles, the straw bundles are supported by the supporting parts 2-3e and then conveyed to the weaving station 19 e.

Referring to fig. 1-19, the working principle of the sizing and knitting device in this embodiment is:

during operation, in the conveying process, when the quantitative separated straws are tightened and bundled, the conveying device conveys the bundled straw bundles to the shaping cavity 4D of the middle shaping mechanism D, as shown in FIG. 6; under the drive of the material guiding driving mechanism, the shaping roller 2d starts to rotate, and then the straw bundle is pushed to move forwards along the shaping cavity 4 d. Because the size of the shaping cavity 4d parallel to the radial direction of the shaping roller 2d is gradually decreased, that is, the distance between the shaping roller 2d and the limiting shaping plate 3d is gradually decreased, the straw bundle gradually passes through the shaping cavity 4d under the pushing of the guide block 2-1d, and the thickness of the straw bundle parallel to the radial direction of the shaping roller 2d is gradually decreased until the thickness is equal to the width of the shaping cavity 4d in the process of moving forwards along the limiting shaping plate 3 d.

Next, when the straw bundle moves close to the end of the sizing cavity 4d, the sizing driving mechanism drives the auxiliary sizing part 5d to move into the sizing cavity 4d, so that the auxiliary sizing part 5d is blocked in front of the movement of the straw bundle, as shown in fig. 7; the auxiliary shaping piece 5d and the material guide blocks 2-1d are positioned on different vertical planes, so that interference cannot occur; with the rotation of the shaping roller 2d, the guide blocks 2-1d push the straw bundles to be extruded on the auxiliary shaping member 5d, so as to shape the straw bundles in the conveying direction, as shown in fig. 8-9; at the moment, the straw bundles are compressed by the shaping roller 2d, the limiting shaping plate 3d, the guide blocks 2-1d and the auxiliary shaping piece 5d at the same time, in the same vertical plane, the shaping roller 2d and the limiting shaping plate 3d shape the straw bundles in the direction perpendicular to the conveying direction of the straw bundles, and the guide blocks 2-1d and the auxiliary shaping piece 5d shape the straw bundles in the direction parallel to the conveying direction of the straw bundles, so that the shapes and sizes of all the straw bundles passing through the shaping cavity 4d tend to be the same; finally, under the driving of the shaping driving mechanism, the auxiliary shaping piece 5d is far away from the shaping cavity 4d, and the shaped straw bundles come out of the shaping cavity 4d along with the material guiding blocks 2-1d, as shown in fig. 10.

In the process, the shaping roller 2d transfers the straw bundles from the conveying device to the front of the weaving station 19e, and simultaneously carries out gradual shaping on the straw bundles, namely, walking extrusion forming is carried out on the straw bundles gradually, so that on one hand, normal transfer work is not hindered, on the other hand, the gradual process can prevent the binding rope from deforming or stretching off, shaping is guaranteed on the premise of binding, and the straw bundles with local bulges can be extruded, so that the straw bundles are smoother; after shaping, the shapes of all the straw bundles are kept consistent, so that the straw mat with better surface quality can be woven.

After shaping is finished, the guide blocks 2-1D push the shaped straw bundles away from the shaping cavity 4D, and at the same time or before, the self-adaptive fixing mechanism moves towards the middle shaping mechanism D under the driving of the transverse transfer mechanism, and the lifting transfer mechanism drives the self-adaptive fixing mechanism to move downwards for a certain distance so as to avoid the straw bundles to be transferred, as shown in fig. 17. When the fixed clamp moves to the lower part of the straw bundle, namely the movable clamp 1e and the fixed clamp 2e are respectively positioned at two sides right below the straw bundle, the movable clamp 1e and the fixed clamp 2e move upwards for a certain distance under the driving of the lifting transmission mechanism until the movable clamp and the fixed clamp are respectively positioned at two sides of the straw bundle, as shown in fig. 18; wherein, the fixed clamp is in an open state, the driving piece 3e is loosened to act on the movable clamp 1e, and the compression spring 4e is in a compressed state; after the movable clamp 1e and the fixed clamp 2e move to the two sides of the straw bundle, the driving piece 3e is loosened to cancel the acting force on the movable clamp 1e, the compression spring 4e starts to recover and release potential energy, and therefore the movable clamp 1e is driven to move towards the fixed clamp 2e until the movable clamp 1e clamps the straw bundle. In the process, due to the particularity of the form of the straws, the thickness of the quantified straw bundles cannot be completely consistent, so when the compression spring 4e drives the movable clamp 1e to transversely move, the larger the thickness of the straw bundles is, the smaller the moving distance of the movable clamp 1e is, and different straw bundles are clamped in a self-adaptive manner, so that the straw bundles can be clamped, and the straw bundles cannot be extruded too much.

When the fixing clamp clamps the straw bundle positioned in the middle shaping mechanism D, the straw bundle transversely moves to a weaving station 19e under the driving of the transverse transmission mechanism, as shown in fig. 19, then a sewing needle 6e pulls an upper needle thread to move downwards and penetrates through a sewing hole 5-1e to pull the upper needle thread to the rotating range of a sewing shuttle 7e, at the moment, the upper needle thread wraps the upper half part of the straw bundle, then the sewing shuttle 7e hooks the upper needle thread and rotates downwards, and the sewing needle 6e returns upwards; in the process of rotation, the upper needle thread and the lower needle thread are staggered. Then, the driving piece 3e is loosened to drive the movable clamp 1e to be far away from the fixed clamp 2e, so that the straw bundle is loosened, and then the fixed clamp moves downwards under the driving of the lifting transmission mechanism until the fixed clamp is lower than the lower edge of the straw bundle; then the traction mechanism drives the straw bundle forwards, and as the upper needle thread and the lower needle thread are staggered, the staggered points of the upper needle thread and the lower needle thread gradually move upwards along with the forward movement of the straw bundle and finally abut against the straw bundle, thereby completing the sewing. Then, the fixing clamp moves to the middle shaping mechanism D again, and the straw bundles are circularly transferred to the weaving station 19e, so that the straw mat is gradually woven. In the weaving process, the straw bundles can be accurately transferred to the weaving station 19e from the middle shaping mechanism D, and can be fixed to prevent deformation in the conveying and weaving processes; in addition, the straw bundles are fixed while being woven, and the straw can be prevented from being shifted.

The above is the preferred embodiment of the present invention, but the embodiment of the present invention is not limited by the above, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be equivalent replacement modes, and all are included in the scope of the present invention.
