Description

TECHNICAL FIELD

[0001] The present application relates to the field of auxiliary mechanical equipment for tire production, in particular to a wire arranging and moving assembly required for automatic winding and rolling of crown strip or bead cover strip and a strip automatic winding device and rolling system comprising the same. BACKGROUND

[0002] The applicant's prior patent application No. 22110965727.3 discloses a strip automatic winding device, strip online manufacturing and multi-station automatic rolling system. In the patent application, a wire arranging and moving assembly is used for moving and arranging the strip, and the rolling of the strip is realized by cooperating with the rotation of the winding shaft. However, the applicant found that the wire arranging and moving assembly can be improved and upgraded during the continuous research and development and continuous improvement, as follows:

[0003] Firstly, the cutting mechanism is relatively complex, and the cutting knife needs to move multiple times to cut the strip. The time required for each cutting of the strip is relatively long, and the cutting efficiency is relatively low.

[0004] Secondly, since the crown strip or bead cover strip has a certain stickiness on the surface, the strip is easy to stick to the surface of the cutting knife after cutting, which causes the cut strip to be unable to be smoothly transported to the surface of the winding shaft during subsequent feeding, resulting in bending and folding of the strip at the conveying end.

[0005] Thirdly, during the rolling of the strip, the rotation speed of the winding shaft changes as the thickness of the strip wound on the winding shaft increases, which causes the tension of the strip to change. If the tension of the strip is too large, the wound strip will stick together, and the strip is not easy to tear during use. If the tension of the strip is too small, there is a risk of hollow bulging of the material roll.

[0006] Therefore, there is an urgent need to develop a wire arranging and moving assembly with simple structure, high cutting efficiency and stable strip tension. SUMMARY

[0034] The above technical solutions of the present application set the cutter assembly 103 downstream of the feeding direction of the feeding plate 1012, and move the telescopic feeding plate 1012 to the downstream direction, so as to convey the strip 300 through the cutter assembly 103 to the downstream of the cutter assembly 103, so that the head of the strip 300 is located at the outer surface of the spool 1, and then the feeding plate 1012 is reset, i.e. reset to the initial position. When the strip 300 is wound and coiled on the spool 1, the cutter in the cutter assembly 103 directly cuts the strip 300. When the head of the strip 300 is conveyed to the outer surface of the spool 1 again, even if the strip is adhered to the cutter after the previous cutting, the strip adhered to the cutter can be peeled off the cutter and conveyed to the outer surface of the spool 1 smoothly during the conveying of the strip by the feeding plate 1012.

[0035] The feeding assembly 101 is arranged approximately vertically to the cutter assembly 103, and the strip passes through the cutter assembly 103 and is wound on the reel 1 through the feeding assembly 101, so that the cutter assembly 103 can directly cut the strip, thereby improving the cutting efficiency.

Optionally, a feeding roller 1010 is further arranged, the feeding roller 1010 is connected with the side plate 1011 through the cutter assembly 103, and is used for supporting the conveying strip and reducing friction during conveying of the strip 300. Further, the feeding plate 1012 has a bottom 1012a, side blocking portions 1012b arranged on both sides of the bottom, and an upper limiting portion 1012c, and the side blocking portions 1012b are used for forming a channel for bearing the strip.

When the strip 300 is cut off by the cutter assembly 103, the retreat stop piece 1015 can drive the strip head to move forward to the front end of the feeding roller 1010, thereby further preventing the strip head from sticking to the cutter and failing to be delivered.

[0037] The cutter assembly 103 comprises a cutter frame, a fourth driver 1032 and a cutter, the cutter frame comprises an upper cutter frame 1031a and a lower cutter frame 1031b, the cutter comprises an upper cutter 1033a and a lower auxiliary cutter 1033b, the fourth driver 1032 is fixed on the lower cutter frame 1031b through a mounting seat 1035, the lower cutter frame 1031b is fixedly connected with the side plate 1011, the power output end of the fourth driver 1032 is connected with the upper cutter frame 1031a, and the upper cutter frame 1031a can be driven to reciprocate on the lower cutter frame 1031b through a slide rail 1034, the upper cutter 1033a is arranged on the upper cutter frame 1031a, and the lower auxiliary cutter 1033b is arranged on the lower cutter frame 1031b.

[0038] The winding moving assembly further comprises a rotatable push rod 1042 and a shaft 1043, the support 107 is provided with a fixing frame 105, the fixing frame 105 is connected with the swing frame 106 through the shaft 1043, the driving end of the first driver 1041 is connected with the push rod 1042, and the push rod 1042 is used for driving the push rod 1042 to move forward or backward, the push rod 1042 can drive the shaft 1043 to rotate and further drive the swing frame 106 connected with the shaft 1043 to rise or fall, and the feeding assembly 101, the pressing roller assembly 102 and the cutter assembly 103 are arranged on the swing frame 106, so that the swing frame 106 can rise or fall together.

When working, the fifth driver 1022 drives the swing frame 1023 to move to drive the pressing roller 1021 connected with the swing frame to press down, so that the material head of the strip conveyed by the feeding assembly 101 is pressed on the reel, and the strip winding can be performed in cooperation with the reel rotation.

[0040] In order to facilitate better adhesion of the strip to the surface of the reel, the rotating end 1023a and the moving end 1023c of the swing frame can be connected through the spring 1024 and can move relatively. When the pressing roller 1021 is pressed down and contacts the reel and is subjected to a downward pressure, the moving end 1023c of the swing frame will continue to move forward along the surface of the reel, so that the front end of the strip is better adhered to the reel. Each driver in the application can be a motor or a pneumatic cylinder.

[0041] The working principle of the present application is briefly described as follows: in the case of strip winding, the third driver 1013 drives the feeding plate 1012 to move forward to drive the material head to be conveyed forward to the cutting knife assembly 103 to pass over the feeding roller 1010; the first driver 1041 drives the swing frame 106 to descend, and drives the feeding assembly 101, the pressure roller assembly 102 and the cutting knife assembly 103 to descend as a whole, so that the feeding roller 1010 is in contact with the surface of the reel; the fifth driver 1022 drives the pressure roller 1021 to press down to press the material head of the strip on the surface of the reel, and cooperates with the rotation of the reel to wind the material head of the strip on the reel, and then the pressure roller 1021 and the feeding plate 1012 are reset to the initial position, the first driver 1041 drives the swing frame 106 to ascend, and further drives the feeding assembly 101, the pressure roller assembly 102 and the cutting knife assembly 103 to ascend as a whole, and the reel rotates to wind the strip; when the strip is cut, the third driver drives the upper cutting knife 1033a to descend to cooperate with the lower cutting knife 1033b to cut the strip directly.
