When the elastic band comes from the feeding device 46 during processing, the swinging device 48 is in standby state, the air cylinder 6 is in an extending state (see fig. 3) at the moment, after the clip of the forming device 49 passes the elastic band clip, the control system of the equipment instructs the air cylinder 6 to ventilate, the air cylinder 6 retracts (see fig. 4) and drives the air cylinder connecting rod joint I5 to pull backwards, so that the T-shaped support rod 2 rotates for a certain angle around the swinging seat 3, the T-shaped support rod 2 drives the whole shearing device 47 to rotate for the same angle around the swinging seat 3 and is in a shearing state, at the moment, the shearing device 47 works, and the elastic band is sheared and then enters the following.

When shearing mechanism 47 vertical direction needs adjustment, rotatory adjusting bolt I14 makes its rise and drives the ascending shearing mechanism 47 of T shape bracing piece 2 and follow and raise, at this in-process, above-mentioned T shape bracing piece 2 drives cylinder connecting rod joint I5, cylinder 6, cylinder connecting rod joint II 7 upwarps, because cylinder connecting rod joint II 7 can drive the rotation axis 13 fixed with connecting rod I9 and rotate, make I9 counter-clockwise turning of connecting rod, thereby realize that T shape bracing piece 2 rises, otherwise, I14 decline of rotatory adjusting bolt, shearing mechanism 47 also can reduce, thereby can make the initial position step-down, adjusting bolt I14 plays the position of adjusting shearing mechanism 47 vertical direction.

When the air cylinder 6 extends out, the air cylinder connecting rod joint I5 advances, the T-shaped supporting rod 2 rotates anticlockwise around the swinging seat 3 to drive the shearing device 47 on the T-shaped supporting rod 2 to raise and retreat, the air cylinder 6 retracts, the air cylinder connecting rod joint I5 retreats, the T-shaped supporting rod 2 rotates clockwise around the swinging seat 3 to drive the shearing device 47 on the T-shaped supporting rod 2 to lower and advance, in the process, the nut 52 is screwed, so that the lower end of the connecting rod II 10 tilts leftwards, the rotating shaft 13 rotates clockwise for a certain angle, thereby driving the connecting rod I9 to rotate clockwise and synchronously for a certain angle around the rotating shaft 13, the connecting rod I9 driving the cylinder connecting rod joint II 7 to retreat, the cylinder connecting rod joint II 7 driving the cylinder 6 and the cylinder connecting rod joint I5 to retreat, thereby driving the T-shaped supporting rod 2 to rotate clockwise by a certain angle, and enabling the shearing device 47 on the T-shaped supporting rod 2 to move to a certain position in the right horizontal direction.

When standby, the shearing device 47 is upwards tilted to achieve the purpose that the guide belt clamp 18 for taking materials turns over for 180 degrees, the deviation of the angle is solved, and the guide belt clamp can be just matched, so that the initial material taking position cannot be mechanically interfered with the forming device 49 beside, the guide belt clamp 18 of the forming device 49 turns over for 180 degrees (see fig. 4), the elastic band can be just fastened (if the elastic band is not fastened, the position can be adjusted through the adjusting bolt I14 and the adjusting bolt II 11), the elastic band is clamped and then turned for 180 degrees, the elastic band is guided into the left and right clamping clamps, when shearing, the shearing device 47 takes the C point of the swinging seat 3 as an axis to reach the shearing position under the action of the air cylinder 6, and the distance requirement of the left clamping clamps is achieved through downward swinging. Because the initial material taking position and the shearing position are changed, the forming device and the shearing device cannot mutually and mechanically interfere, the length of the guide belt clamp 18 of the forming device 49 can be adjusted to 8 cm at the shortest, and the shortest elastic band can be twice the length of the guide belt clamp 18 of the forming device (the guide belt clamp needs to be turned over by 180 degrees), namely 16 cm.

When the elastic band is processed, the twisted elastic band can be kept flat and fed in through the knotting prevention wheel, then the elastic band is shaped through the thermal preshrinking device with adjusted temperature, the elastic band is flat and easy to process, then the elastic band passes through the presupporting wheel 28 and finally passes through the guide device 29 to enter the belt feeding wheel assembly 31, the material shortage sensor 24 is also arranged beside the presorting wheel 28, when the elastic band is not prepared enough, the Z-shaped rod 32 can be triggered, so that the presorting wheel 28 can automatically feed for supplement, the guide device 29 is also provided with a logo positioner 30 which has the locating function of logo mark, when the elastic band is fed out, the conduction band clamp 18 of the forming device 49 is turned over 180 degrees, the elastic band is led into the left and right clamping clamps, the left and right clamping clamps clamp the elastic band, the air cylinder 6 of the swinging device 48 retracts, the shearing device 47 is started for cutting, the conduction band clamp 18 is, then the left and right rotary cylinders drive the left and right clamp clips to reset, the feeding connecting seat 35 feeds the elastic band to the sewing machine, the presser foot of the sewing machine is pressed down, the left and right clamp clips loosen the elastic band, the feeding connecting seat 35 resets, after the sewing machine is sewed, the sewing device 50 pushes the annular elastic band into the material receiving rod, and the whole set of action is completed.

In conclusion, according to the automatic elastic band connecting machine provided by the embodiment, the original cutting device which cannot swing can change the initial material taking position and the cutting position through the swing device by adding the swing device, so that the automatic elastic band connecting machine is more compact and reasonable in matching with a forming device, and the purpose of enabling the annular elastic band to have the minimum circumference of 16 cm is achieved.
