Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of medical product production equipment, and relates to a compact integrated high-speed folding machine and a linkage production method. BACKGROUND

[0002] In medical products, a surgical gauze is involved, including gauze with and without barium threads, and also different types of gauze with sparse and dense gauze. The current preparation method is to cut the gauze sheet first, then fold the gauze sheet, then press and attach the barium thread on the gauze sheet, then fold manually and sew the barium thread in the gauze folding layer. The process of attaching the barium thread to the gauze relies on the barium thread unwinding mechanism to pull the barium thread, so that the barium thread is pressed on the gauze sheet by the pressure equipment when passing through multiple gauze sheets. After the barium thread is attached to multiple gauze sheets, it is still connected to each other, and a cutting device is still needed to cut the barium thread. Since there is a certain distance between every two gauze sheets, the cutting causes a large waste of barium thread. Secondly, gauze sheets with and without barium threads cannot be produced on the same machine. SUMMARY

The adsorption and transfer mechanism and the unwinding mechanism are respectively located on both sides of the vertical center line. The hooking and folding mechanism is arranged on one side of the adsorption and transfer mechanism.

[0014] S1, Unwinding: The unwinding mechanism releases the yarn roll, and the yarn passes through the folding mechanism, heating roller, and traction roller in sequence to reach the slitting mechanism. In this step, the atomizing and wetting device set around the unwinding mechanism atomizes and wets the yarn released between the heating roller and the unwinding mechanism.

[0015] In S1, if the production is bar gauze, it also includes paying off, that is, the bar wire head in the bar wire box behind the paying-off mechanism is led out, passes through the bar wire traction hook on the upper part of the gauze, goes over the folding edge mechanism to the setting wheel, and then passes through the bar wire guide groove and the heating roller and is pressed by the upper pressure roller;

[0016] In S2, heating, the heating roller performs regional heating on the gauze, and the temperature of the subsequent crease area and the bar wire area of the gauze is controlled respectively; in this step, the subsequent crease area of the gauze passes through the non-heating section of the heating roller, and the bar wire area and the remaining area of the gauze pass through the heating section of the heating roller for heating;

[0017] In S3, slitting, the traction roller clamps the gauze to guide it between the bottom knife roller and the cutting knife roller, the bottom knife roller and the cutting knife roller rotate in opposite directions, the cutting knife on the cutting knife roller presses the gauze on the bottom knife of the bottom knife roller and cuts it off, and the gauze is cut into gauze pieces; in this step, since the bottom knife is recessed in the bottom knife roller and the cutting knife extends out of the cutting knife roller, after cutting the gauze, the gauze end is clamped again by the bottom knife roller and the cutting knife roller to form a tensioning force, avoiding the rebound of the gauze end to cause the gauze to be unable to be cut again;

[0018] In S4, first insertion and transfer, the gauze piece after cutting is adsorbed on the roller body surface by the adsorption hole on the roller body surface, and is supported by the first insertion knife on the bottom knife roller; when the bottom knife roller rotates, the first insertion knife inserts the front end of the gauze piece into the folding and clamping slot of the large drum; at the same time, the folding and clamping knife in the folding and clamping slot clamps the gauze piece, and the bottom knife roller continues to rotate and the first insertion knife exits the folding and clamping slot; in this step, the front end of the gauze piece is folded by one fourth;

[0020] In S6, mid-rolling, when the large drum drives the gauze piece to reach the pressure roller, the pressure roller rotates to drive the three pressing heads to roll the pressed gauze piece; in this step, the two fork levers that press the gauze piece are located in the space on both sides of the middle pressing head of the three pressing heads;

[0021] S7, when the gauze piece reaches the second inserting roller driven by the large drum, the folding and clamping knives clamping the first and second folds of the gauze piece are loosened, the middle inserting knife rotates to insert the middle part of the gauze piece into the folding and clamping slot of the large drum, the folding and clamping knives in the folding and clamping slot clamp the gauze piece, and the suction holes are arranged on both sides of the folding and clamping slot; at the same time, the two prong rods clamping the gauze piece are flipped in opposite directions to release the first and second folds of the gauze piece; in this step, the gauze piece is folded and centered, and the suction force generated by the suction holes acts on the two ends of the gauze piece to prevent the two ends of the gauze piece from falling and scattering due to gravity;

[0022] S8, when the gauze piece reaches the suction and transfer mechanism driven by the large drum, the folding and clamping knives clamping the folded and centered gauze piece are loosened, the suction force generated by the suction petals is greater than the suction force of the suction holes on both sides of the folding and clamping slot, the suction petals adsorb the gauze piece, and the suction and transfer mechanism rotates to transfer the gauze piece; in this step, the gauze piece after the third fold forms a strip-shaped gauze structure, and the length direction of the strip-shaped gauze structure is the same as the direction of the negative pressure shaft of the suction and transfer mechanism;

[0023] S9, fourth fold, when the suction petals reach the hooking and folding mechanism, the hooking and folding plate is located in the hooking groove of the suction petals, at the same time, the longitudinal sliding table drives the hooking and folding plate to exit the hooking groove, hooks the strip-shaped gauze, and retreats into the gap between the receiving groove and the guide plate, and the strip-shaped gauze is folded on both sides of the gap; in this step, one third of the end of the strip-shaped gauze is folded;

[0024] S10, clamping, the sliding plate drives the buffer to pass through the guide plate to clamp the fourth fold of the strip-shaped gauze on the wall plate outside the receiving groove, the longitudinal sliding table drives the hooking and folding plate to exit the hooking groove, and the push plate synchronously exits the end of the receiving groove;

[0025] S11, fifth fold, the sliding plate drives the buffer to move to one side to release the clamping of the folded part of the strip-shaped gauze; at the same time, the horizontal sliding table drives the inserting folding plate to pass through the folding slot on the guide plate and the receiving groove to fold one third of the other end of the strip-shaped gauze, and the folded one third coincides with the other one third; in this step, the folded gauze is located in the receiving groove, and the horizontal sliding table drives the inserting folding plate to exit the folding slot;

[0026] S12, storage, during the process of the hooking and folding plate retreating into the gap between the receiving groove and the guide plate, the push plate is synchronously retreated and slides in the receiving groove to push the folded gauze in the receiving groove backward.

[0029] The large drum cooperates with the slitting mechanism and the inserting and folding mechanism to complete multiple folds of the gauze piece in the axial direction during rotation, and finally forms the strip-shaped gauze.

[0030] The strip-shaped gauze is transferred to the hooking and folding mechanism by the adsorption and transferring mechanism, and the hooking and folding mechanism radially folds the strip-shaped gauze.

[0031] Two unwinding mechanisms are used to unwind at the same time, which can produce gauze pieces without barium wires, can produce gauze pieces with barium wires, and can produce both at the same time.

[0032] The barium wire is attached to the gauze piece as a whole at the heating roller, and the cutting and folding of the gauze piece are synchronized during the cutting and folding process, so that the barium wire will not be wasted. BRIEF DESCRIPTION OF DRAWINGS
