Referring to fig. 1 and 2, an air cylinder automatic control thread cutting device structurally comprises a first support plate 1, a second support plate 2, a thread clamping device and a cutter assembly; the first support plate 1 and the second support plate 2 are arranged in parallel and are vertically fixed on a rack of the equipment; is erected between the first support plate 1 and the second support plate 2; the cutter assembly is arranged on the first support plate 1.

Further, the wire clamping device consists of a clamping cylinder 31, a push rod 32, a clamping sleeve 33, a return spring 34 and a support roller 35; the push rod 32, the clamping sleeve 33 and the supporting roller 35 are coaxial, the right end of the supporting roller 35 is sleeved on the second support plate 2, and a self-lubricating bearing is nested between the push rod and the second support plate; the inner ring of the reset spring 34 is sleeved at the left end of the support roller 35, and the clamping sleeve 33 is sleeved at the outer ring of the reset spring 34; the right end of the push rod 32 is matched with the clamping sleeve 33, the left end of the push rod is hinged with the head of a piston rod of the clamping cylinder 31, and the push rod 32 can push the clamping sleeve 33 to slide rightwards under the driving of the clamping cylinder 31. By adopting the structure, namely the thread clamping device, the cotton thread can not run when the cutter cuts off, and the cutting off action is accurate and reliable.

Further, the head of the push rod 32 is a vertebral body; the clamping sleeve 33 is provided with an inner conical surface; the shapes of the cone body and the inner cone surface are matched.

Further, the cutter assembly consists of a first rotating shaft 41, a cutter bar 42, a cutter 43 and a driving assembly; the first rotating shaft 41 is arranged on the first support plate 1 through a bearing with a seat, the left end of the first rotating shaft is connected with the driving component, and the right end of the first rotating shaft is connected with the cutter bar 42 through a key; the cutter 43 is fixed to the cutter bar 42.

Further, the driving assembly is composed of a rotating cylinder 44, a hinge sleeve 45, a first sector gear 46, a second sector gear 47 and a second rotating shaft 48; the first sector gear 46 is sleeved at the left end of the first rotating shaft 41; the second sector gear 47 is sleeved at the left end of the second rotating shaft 48; the first sector gear 46 and the second sector gear 47 are meshed; the second rotating shaft 48 is arranged on the first support plate 1 through a bearing with a seat; the rotary cylinder 44 is hinged to the second sector gear 47 via a hinge sleeve 45 fixed to the end face of the second sector gear 47. By adopting the structure, the cutter assembly is automatically carried out, the manual work is replaced, the quick response of the cutting action is ensured, and the labor cost is reduced

The working principle is as follows: when the equipment is wound to the required length of a product, the control system controls the piston rod of the clamping cylinder to extend out through the electromagnetic valve, the piston rod drives the push rod to push the clamping sleeve to move rightwards, the reset spring is compressed in the process of moving rightwards of the clamping sleeve, and meanwhile, the gap between the clamping sleeve and the supporting roller is continuously reduced until the cotton thread is clamped.

Treat that the clamp sleeve presss from both sides tight back with cotton thread 5, the piston rod of rotating cylinder retracts, drives the rotation of second sector gear to drive first pivot through the first sector gear rather than meshing and rotate, also drive the cutter that is fixed in on the cutter arbor and rotate when first pivot is pivoted, the cutter rotates the in-process and can cut off the cotton thread, so far has just accomplished the action of cutting off of cotton thread 5.

After the cotton thread 5 is cut off, a piston rod of the rotary air cylinder extends out, and drives the cutter to reset through gear transmission to wait for next cutting off; meanwhile, the piston rod of the clamping cylinder retracts, the push rod is separated from the clamping sleeve, and the clamping sleeve resets under the action of the reset spring, so that the cotton thread is loosened.

It should be noted that, the electrical components appearing in this document are electrically connected to an external master controller and a 220V commercial power, the master controller may be a common known device controlled by a computer or the like, and the rotary cylinder and the clamping cylinder herein are both connected to an external air source, and the master controller is used for controlling the operation of the rotary cylinder and the clamping cylinder.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
