Description

Nipper mechanism of comber

Technical Field

The invention relates to an intelligent combing machine, in particular to a nipper mechanism of the combing machine.

Background

The main function of the nipper mechanism in the combing machine is to hold the rear end of the fiber bundle for cylinder carding and send the carded fiber bundle to the separating jaw to realize the joint of new and old fiber webs, and the nipper mechanism and the cylinder mechanism can fully play the role of the combing machine only by effective motion coordination. At present, the requirements on the low falling rate of machine-picked cotton combing and chemical fiber combing market are increasingly harsh, and the common effective means for realizing the low falling rate of combing is that the combing process selects smaller noil gauge, but when the high-efficiency cotton spinning combing machine selects small noil gauge, the lower nipper in the nipper mechanism is easy to collide with cylinder needle teeth to damage the cylinder needle teeth and damage the nipper, so that the economic loss of enterprises is greatly increased.

Disclosure of Invention

In order to overcome the defects, the invention provides a nipper mechanism of a combing machine, wherein when the combing machine is arranged in any noil gauge process, the lower nipper cannot collide with cylinder needle teeth in the moving process of the nipper mechanism.

The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a comber nipper mechanism, includes cylinder axle, nipper front swing arm, nipper back swing arm, nipper seat and lower nipper, the pivot of nipper front swing arm one end is on the cylinder axle, and the pivot of nipper back swing arm one end is on the nipper axle, and cylinder axle and nipper axle parallel arrangement are on the comber, and nipper seat one end is articulated with the nipper front swing arm other end, and the nipper seat other end is articulated with the nipper back swing arm other end, lower nipper fixed mounting is in the inside lower extreme of nipper seat, lower nipper forms acute angle with nipper seat both ends line, and lower nipper is located the top of nipper seat both ends line.

The utility model provides a swing arm behind pincers board seat, pincers board front swing arm, pincers board constitutes and uses pincers board axle and cylinder axle as the double crank mechanism of fixed fulcrum to realize pincers board seat drive down pincers board's back-and-forth swing through pincers board axle's rotation, this patent changes the position relation of pincers board and cylinder needle tooth point motion in-process down of solid dress on the pincers board seat through above-mentioned mechanism, its positive effect is: the combing machine is set to be any noil gauge process, the lower nipper cannot collide with the tooth tips of the cylinder needle teeth in the nipper moving process, and the mechanism can meet the normal production of the minimum noil gauge of the high-efficiency combing machine and save materials to the greatest extent.

As a further improvement of the invention, the clamp plate seat is in a V-shaped structure, the lower clamp plate is fixedly arranged on one side wall of the V-shaped structure, and the clamp plate seat is formed into a bent structure which is beneficial to the fixed installation of the lower clamp plate.

As a further improvement of the invention, the connection position of one end of the lower nipper and the nipper seat is just overlapped with the hinging position of the nipper seat and the nipper front swing arm.

As a further improvement of the invention, the distance between the nipper seat and the hinge shaft which is hinged with the nipper front swing arm and the nipper rear swing arm is 187mm.

As a further improvement of the invention, an upper nipper is also arranged, the upper nipper is fixedly arranged at the upper end in the nipper seat, the distance between the fixed connection point of the upper nipper and the nipper seat and the hinge shaft of the nipper seat and the front swing arm of the nipper is 75mm, and the fixed connection point of the upper nipper and the nipper seat, the two ends of the nipper seat and the hinge points of the nipper seat and the rear swing arm of the nipper are not in the same straight line.

As a further improvement of the invention, the distance from the pivot axis of the front swing arm of the nipper to the cylinder shaft to the pivot axis of the front swing arm of the nipper to the nipper seat is 74mm, and the distance from the pivot axis of the rear swing arm of the nipper to the pivot axis of the nipper to the rear swing arm of the nipper to the pivot axis of the nipper seat is 82mm.

The beneficial effects of the invention are as follows: according to the invention, the combing machine is set to be an arbitrary noil gauge process, and the lower nipper cannot collide with the cylinder needle teeth in the movement process of the nipper mechanism, so that the normal production of the minimum noil gauge of the high-efficiency combing machine is satisfied, and the materials can be saved to the greatest extent.

Detailed Description

Examples: a nipper mechanism of a combing machine comprises a cylinder shaft O ₁ Clamp plate shaft O ₂ The front swing arm 2 of the clamp plate, the rear swing arm 5 of the clamp plate, the clamp plate seat 4 and the lower clamp plate 3, wherein one end of the front swing arm 2 of the clamp plate is pivoted with the cylinder shaft O ₁ On, swing arm other end is articulated with pincers board seat one end before the pincers board, and the distance between pivot and the articulated shaft of its pincers board swing arm before the pincers board is 74mm, and pincers board back swing arm 5 one end pin joint is epaxial in pincers board, and pincers board back swing arm other end is articulated with pincers board seat other end, and the distance between pivot and the articulated shaft of pincers board back swing arm 5 is 82mm, and the distance between the pin joint at pincers board seat both ends is 187mm, lower pincers board fixed mounting is in the inside lower extreme of pincers board seat, lower pincers board and pincers board seat both ends line formation acute angle, and lower pincers board is located pincers board seat both ends line's top still is equipped with pincers board, and upper pincers board and pincers board seat fixed connection, pincers board seat 4 and pincers board's the tie-in point O that goes up the pincers board ₃ The distance between the hinge points of the two ends of the clamp plate seat and one end of the clamp plate seat 4 is 75mm, and the hinge points of the two ends of the clamp plate seat and the three points of the fixed connection points of the clamp plate seat and the upper clamp plate are not in the same straight line, wherein the clamp plate seat 4, the clamp plate front swing arm 2 and the clamp plate rear swing arm 5 form a cylinder shaft O ₁ With the nipper shaft O ₂ Is a double crank mechanism for fixing a pivot and passes through a nipper shaft O ₂ The rotation of the clamp plate seat 4 drives the lower clamp plate 3 to swing back and forth.

The nipper mechanism of the combing machine changes the position relation between the lower nipper 3 fixedly arranged on the nipper seat 4 and the cylinder needle teeth in the moving process, and the specific method is as follows: through the nipper shaft O ₂ The rotation of the clamp plate seat 4, the clamp plate front swing arm 2 and the clamp plate rear swing arm 5 form a cylinder shaft O ₁ With the nipper shaft O ₂ The double-crank mechanism for fixing the pivot moves according to a certain rule, so that the movement of the lower nipper 3 on the nipper seat 4 is realized, and particularly, no intersection exists between any point on the lower nipper 3 and the movement track 1 of the pin tooth tip of the cylinder in the movement process, namely, the situation of collision does not occur.
