The invention also discloses a cloth slitting and cutting method adopting the cloth production slitting mechanism, which comprises the following steps:

unwinding cloth wound on an unwinding roller, and conveying the unwound cloth downwards in a hanging manner after the cloth is pulled by a traction unit;

when the hanging length of the cloth reaches the set length, driving the switching driving device to upwards switch the cloth placing plate which is in the vertical state to the horizontal state, in the process, gradually switching the lower part of the hanging cloth from the vertical state to the horizontal state along with the switching movement of the cloth placing plate and supporting the cloth placing plate in the horizontal state, and forming a curved state with an upward opening by the cloth between the traction unit and the cloth placing plate in the horizontal state, wherein the trough of the curved cloth gradually moves downwards along with continuous unwinding of the unwinding unit, cutting the cloth supported on the cloth placing plate in the horizontal state by the cutting unit, and forming a plurality of block-shaped cloth in the width direction of the cloth;

Then, the cut cloth blocks are ejected upwards out of the cloth placing plate through the upward ejection movement of the ejection unit, and a translation gap between adjacent block cloths is formed in the ejection process;

removing the block-shaped cloth, resetting the cloth plate in a horizontal state to a vertical state by resetting the ejection unit and driving the switching driving device again, and hanging the bent cloth downwards again

The invention has the advantages that: the cloth is cut off section by section, so that a conventional winding device cannot be used as guiding power for conveying the cloth, the cloth is drafted after being pulled by the traction unit, the real-time conveying of the cloth is realized by matching unreeling and unreeling of the unreeling roller under the action of gravity of the cloth, the free end of the cloth can be freely kept in an unfolded state under the action of gravity, and if the pulled cloth is changed into a horizontal state, the pulled cloth is piled up and stagnated in a horizontal direction, so that real-time continuous conveying movement is difficult to realize; because the cloth placing plate is switched from the vertical state to the horizontal state, the lower part of the suspended cloth is gradually switched from the vertical state to the horizontal state along with the switching of the cloth placing plate and is supported on the horizontal cloth placing plate, the downward movement of the suspended cloth is provided with a guiding function by utilizing the direction change of the cloth placing plate when the cloth placing plate is in the vertical state, and the cloth can be driven to move to the horizontal state when the cloth placing plate is switched to the horizontal state, so that the possibility of subsequent cutting is provided;

The lower part of the cloth is changed from a vertical state to a horizontal state in a continuous gradual change process, so that the phenomenon of wrinkling and deviation of the cloth in the direction switching process can be reduced as much as possible. When the cloth placing plate is switched from the vertical state to the horizontal state, the cloth between the traction unit and the horizontal cloth placing plate forms a bending state with an upward opening, and the continuous unreeling and unreeling of the unreeling roller are matched by utilizing the drooping section of the bending cloth, specifically, the drooping section further sinks to the trough position of the drooping section under the action of gravity to balance the length of the unreeled cloth, so that a section of cloth which is horizontally paved on the cloth placing plate at present is not disturbed.

According to the invention, the ejection unit is used for ejecting a plurality of block-shaped cloths upwards to the cloth placing plate, and a translational gap is formed between adjacent block-shaped cloths in the ejection process, so that dislocation space is provided for different block-shaped cloths to realize different blanking or separate blanking.

Further, the switching driving device can cooperate linear motion between the driving screw rod and the mounting seat with the guide rack and the rolling gear to realize state switching between the lower vertical state and the higher horizontal state of the cloth placing plate, and the two switching processes are continuous change processes, namely, the displacement of the cloth placing plate in the height direction and the change of the rotation of the cloth placing plate are gradual change rather than instantaneous, so that the switching driving device has the technical effects of convenience in operation, accuracy in operation and good stability in the switching process.

Further, through the cooperation between the cutting unit and the ejection unit, the invention realizes the sequential cooperation among the cutting action, the stationary cutting knife after cutting, the ejection action of the blocky cloth and the separation action of the blocky cloth by taking the movement of the lower pressing rod as the main drive, and has strong process continuity. In the cutting operation, when a composite fabric having a relatively thick resin coating layer on the surface thereof is cut, there is a technical defect that the fabric is not completely cut due to partial fibers not being cut. Because the cutting edge of the cutting knife is still static on the cloth placing surface when the blocky cloth is ejected, the blocky cloth moves upwards relative to the cutting edge of the cutting knife in the upward ejection process of the cloth placing table, the secondary cutting effect can be achieved, and the technical defect that the complete cutting of the cloth cannot be realized in the cutting action process is overcome. The auxiliary supporting section is used for supporting the cloth plate, and the stability of the horizontal cloth plate is improved before the cloth supported on the horizontal cloth plate is cut by the cutting knife of the cutting unit.

Further, in the process of rotating the pivoting connecting rod, the transmission gear rotates along with the pivoting connecting rod and rolls along the axial direction of the fixed annular gear, and the transmission gear rolls to drive the wheel gear and the contact wheel to rotate through the transmission of the coaxial gear and the sliding rod. Thereby realizing that the contact end of the pivoting connecting rod is matched with the pressing rod in a rolling contact manner. In this way, the sliding contact between the contact end of the pivot connecting rod and the pressing rod is optimized into rolling contact, and in the contact process, the contact wheel of the contact end of the pivot connecting rod realizes the area of invariable change and contact with the pressing rod through continuous rotation, so that the contact stress is more balanced, and the relative abrasion is further reduced.

Further, before the cloth placing plate is switched from the vertical state to the horizontal state, cloth is pressed on the cloth placing plate in advance through a lower pressing cylinder, the suspended cloth is divided into upper-section cloth and lower-section cloth from top to bottom, the lower-section cloth of the suspended cloth belongs to the lower-section cloth, and the lower-section cloth is gradually moved downwards along with the cloth placing plate in the process of switching from the vertical state to the horizontal state and in the process of gradually moving the trough of the bent cloth, the length of the cloth on the cloth placing plate cannot be changed due to the limiting effect of the lower pressing block, so that the stability of the cloth horizontally paved on the cloth placing plate is ensured, the length change caused by the movement of the cloth placing plate is avoided, and the smooth operation of the subsequent cutting work is further influenced.

Further, the X-axis screw rod is driven to rotate by starting the driving motor, so that the driving installation seat slides along the length direction of the cloth placing plate, and in the process of sliding of the driving installation seat, the main driving gear is rotated by utilizing the meshing relationship of the main driving gear and the main driving rack, so that the flattening roller rotates while moving along the length direction of the cloth placing plate, and flattening of cloth or strip-shaped cloth on the opposite cloth plate is realized.

Furthermore, as the translational gaps are generated between the various block-shaped cloths after being cut in the invention in the upward ejection process, the mutual separation is realized, and thus, space conditions can be provided for the subsequent separate entry into different air channels. Through different wind channels, different blocky cloths are blown to different areas for concentration, and classification of the blocky cloths with different specifications is achieved.

Further, before the cutting action occurs, the supporting bottom rod moves downwards until the supporting bottom rod is contacted with the frame, and then moves downwards along with the further downward movement of the supporting bottom rod, and the supporting bottom rod overcomes the elastic acting force of the supporting pressure spring and moves downwards relative to the supporting bottom rod at the moment, so that when the sliding rod contacts with the inclined plane of the power block in the inner cavity of the supporting bottom rod, the part of the power block slides out of the inner cavity of the supporting bottom rod and is supported at the bottom of the horizontal cloth placing plate, and the bottom of the horizontal cloth placing plate is supported through the power block, so that the bearing stability of the horizontal cloth placing plate is improved.

Furthermore, before the cutting action occurs, when the sliding rod continues to move downwards, namely when the cutting action occurs and the ejection work occurs, the sliding rod continues to move downwards at the moment, and does not move upwards with the power block but is converted into sliding parallel to the bottom of the cloth placing plate, so that the downward movement of the sliding rod caused by the cutting action and the ejection work is ensured not to affect the cloth placing plate supported by the power block. In addition, the supporting action of the power block is to move upwards to be in extrusion contact with the bottom of the cloth placing plate and then translate. The extrusion contact (compressed by the buffer compression spring) further ensures the stability and the compactness of the support by using the resilience force of the buffer compression spring. If the supporting action of the power block is not to move upwards to be in extrusion contact with the bottom of the cloth placing plate and then to translate, but the power block is directly translated out of the sliding through hole to be in contact with the bottom of the cloth placing plate, the extrusion contact cannot be used. Because, the buffering pressure spring is compressed when the precondition of extrusion contact, and the buffering pressure spring is under the natural state, and the height of power piece is higher than the height of putting the bottom of cloth board, the power piece can't translate to the bottom of putting the cloth board.

In the cutting operation, when a composite fabric having a relatively thick resin coating layer on the surface thereof is cut, there is a technical defect that the fabric is not completely cut due to partial fibers not being cut. Because the knife edge of the cutting knife 31 is still static on the cloth placing surface 411 when the block cloth 102 is ejected, the block cloth 102 moves upwards relative to the knife edge of the cutting knife 31 in the upward ejection process of the cloth placing table 51, the effect of secondary cutting can be achieved, and the technical defect that the complete cutting of the cloth cannot be realized in the cutting action process is overcome.

Compared with the prior art, the invention has the following technical effects:

the cloth is cut off section by section, so that a conventional winding device cannot be used as guiding power for conveying the cloth, the cloth is drafted after being pulled by the traction unit 2, the real-time conveying of the cloth is realized by matching unreeling and unreeling of the unreeling roller under the action of gravity of the cloth, the free end of the cloth can be freely kept in an unfolded state under the action of gravity, and if the pulled cloth is changed into a horizontal state, the cloth can be piled and stagnated in a horizontal direction after being pulled, and real-time continuous conveying movement is difficult to realize; because the cloth placing plate 41 is switched from the vertical state to the horizontal state, the lower part of the suspended cloth is gradually switched from the vertical state to the horizontal state along with the switching of the cloth placing plate 41 and is supported on the horizontal cloth placing plate 41, the downward change of the cloth placing plate 41 is utilized to provide a guiding function for the downward movement of the suspended cloth when the cloth placing plate 41 is in the vertical state, and the cloth can be driven to move to the horizontal state when the cloth placing plate 41 is switched to the horizontal state, so that the possibility for the subsequent cutting is provided; the lower part of the cloth is changed from a vertical state to a horizontal state in a continuous gradual change process, so that the phenomenon of wrinkling and deviation of the cloth in the direction switching process can be reduced as much as possible. When the cloth placing plate 41 is switched from the vertical state to the horizontal state, as the cloth between the traction unit 2 and the horizontal cloth placing plate 41 forms the curved state 101 with the upward opening, the continuous unreeling and unreeling of the unreeling roller are matched by utilizing the sagging section of the cloth of the curved state 101, particularly, the length of the unreeled cloth is balanced by further sinking the trough position of the sagging section under the action of gravity, so that the length of a section of cloth which is horizontally paved on the cloth placing plate 41 at present is ensured not to be disturbed. According to the invention, the ejection unit 5 is used for ejecting the plurality of block-shaped cloths 102 upwards to the cloth placing plate 41, and a translational gap is formed between adjacent block-shaped cloths 102 in the ejection process, so that a dislocation space is provided for realizing different blanking or separating blanking among different block-shaped cloths 102. The support of the opposite cloth plate 41 by the auxiliary support section takes place before the cutting blade 31 of the cutting unit 3 cuts the cloth supported on the horizontal cloth plate 41, so that the stability of the load bearing of the horizontal cloth plate 41 is improved.

In summary, the slitting mechanism for cloth production can realize that the cloth is continuously unwound and cut one section by one section on the premise that the cloth is not stopped, so that a plurality of block-shaped cloths 102 are formed, and after the cloth is cut, a translation gap is generated between the adjacent block-shaped cloths 102, so that the separation between the block-shaped cloths 102 is realized.

When the sliding rod 3212 moves upwards, the elastic parts such as tension springs and compression springs are reset, so that the parts are reset.

In the invention, before the cutting action occurs, when the sliding rod 3212 continues to move downwards, namely when the action of the cutting knife 31 occurs and the ejection work occurs, the sliding rod 3212 does not move upwards along with the power block 324 but is converted into sliding parallel to the bottom of the cloth 41, so that the downward movement of the sliding rod 3212 caused by the cutting action and the ejection work does not affect the cloth 41 supported by the power block 324. In addition, the supporting action of the power block 324 of the invention is to move upwards to be in pressing contact with the bottom of the cloth placing plate 41 and then translate. The extrusion contact (compressed by the buffer compression spring 3218) further ensures the stability and the compactness of the support by using the resilience force of the buffer compression spring. If the supporting action of the power block 324 is not to move upwards to be in pressing contact with the bottom of the cloth placing plate 41 and then to translate, but the power block 324 is directly translated out of the sliding through hole to be in contact with the bottom of the cloth placing plate 41, the pressing contact cannot be used. Because, on the premise of pressing contact, the buffer compression springs 3218 are compressed, and in a natural state, the height of the power blocks 324 is higher than the height of the bottom of the cloth placing plate 41, and the power blocks 324 cannot translate to the bottom of the cloth placing plate 41.

The above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
