Description
Technical Field
The invention relates to the technical field of functional materials, in particular to a metal sewing thread anti-winding thread supply tool.
Background
Generally, an industrial sewing machine is provided with a plurality of thread supply discs on which thread coils are placed; when the sewing machine works, the wire coil or the wire coil automatically rotates under the action of tension, and the wire is continuously led out. However, the traditional stainless steel sewing thread has the characteristics of high specific gravity, small friction force and rebound resilience, so that the coil is easy to loosen when the sewing thread coil is vertically placed, the loosened coil is accumulated, and the coil is easy to wind and knot when the sewing machine automatically takes out the thread, thereby influencing the normal use of the sewing machine; in addition, because the specific gravity is large, when the sewing machine takes out the thread, the thread coil cannot rotate along with the sewing machine due to large friction resistance, the thread is blocked, the manual intermittent thread releasing is relied on, the manually stacked coil is easy to wind and knot, and the labor efficiency is low.
The existing sewing process belongs to labor-intensive industry, and along with the development of industrial automation, the automation requirement of the sewing process is more and more urgent.
Disclosure of Invention
Aiming at the problems of the industrial sewing machine, the invention aims to provide a metal sewing thread anti-winding thread supply tool which can solve the problems of easy winding, easy knotting and easy clamping stagnation when the sewing machine automatically takes out threads; meanwhile, the metal sewing thread has wide application range and can be used for metal sewing threads with various specifications.
The purpose of the invention is realized by the following technical scheme:
the utility model provides a metal sewing thread antiwind supplies line frock, installs on the frock, realizes that the coil of wire is fixed through the trepanning at coil of wire center, its characterized in that: the steering wheel consists of a steering rod, a wire coil, a bearing, a mandrel, a sleeve, an end cover and a rubber sleeve; the steering rod is of an inverted L-shaped cylindrical structure, corners of the inverted L-shaped cylindrical structure are of an inverted arc structure, the inverted L-shaped cross rod and the inverted L-shaped vertical rod form a certain angle, and the angle is 92-94 degrees; the wire coil is fixed on the inverted L-shaped cross rod, and the right end face of the wire coil is a certain distance away from the right end face of the inverted L-shaped cross rod; the mandrel is fixed on the right end face of the inverted L-shaped cross rod, the left end face of the mandrel is coplanar with the right end face of the inverted L-shaped cross rod, the central axis of the mandrel is collinear with the central axis of the inverted L-shaped cross rod, and the length of the mandrel is not more than 1/3 which is half of the length of the coil and not less than the length of the coil; the number of the bearings is at least two, and at least one bearing is fixed at the left end and the right end of the mandrel respectively; the sleeve is fixed on the bearing; the end cover is fixed at the rightmost end of the sleeve and used for preventing the sleeve from moving to the right side; the two rubber sleeves are respectively sleeved at the left end and the right end of the sleeve, and the inner wall of each rubber sleeve is in interference fit with the outer walls of the left end and the right end of the sleeve; the rubber sleeve outer wall is the big round platform structure in the little left side in right side, its right end diameter ratio the diameter of trepanning is 1mm, the coil of wire installation of being convenient for, the rubber sleeve left end diameter ratio the diameter of trepanning is 1mm big at least.
The structure can avoid the loose and drooping of the wire coil and the winding and knotting of the wire coil by converting the traditional vertical position of the steering rod into a partial horizontal position; the sliding friction of the original thread reel is converted into rolling friction, so that the thread coil automatically rotates under the action of the traction tension of the sewing machine, the thread is continuously fed out, the production efficiency is improved, and the mutual winding of metal sewing threads during thread taking is avoided; the length of the mandrel is limited, so that the condition that when the tool is used for supplying wires to operate, radial runout occurs at the rightmost end due to the overlong mandrel, the stability of the tool is influenced, and the mandrel is not firmly fixed due to the overlong mandrel is avoided; the rubber sleeve provides certain buffer force, further avoids radial runout and guarantees the stability of frock.
After the steering rod is converted into a partial horizontal position, the coil of thread can move towards the right side due to the action of centrifugal force during thread taking (the direction of taking metal sewing threads in industry is fixed, so that the coil of thread can only move towards the right side and cannot move towards the left side under the action of centrifugal force), and the coil of thread falls off, and the thread supply efficiency and the production progress are influenced; according to the structure, the angle between the inverted L-shaped cross rod and the inverted L-shaped vertical rod (the angle is large, so that a coil slides left and is contacted with a wire coil, the stability of the wire supply is influenced, and the angle is too small and is consistent with the angle when the inverted L-shaped cross rod is horizontal, so that the coil moves right and falls off) is matched with the shape structure of the rubber sleeve and the length of the mandrel, so that the coil is prevented from moving when a tool supplies wires, the working efficiency of the tool is ensured, and the stability of the wire supply is also ensured.
Furthermore, the distance between the right end face of the wire coil and the right end face of the inverted L-shaped cross rod is 2 cm-4 cm.
Further, the number of the bearings is two.
Further, for convenience of installation, the diameter of the rightmost end of the outer wall of the rubber sleeve is 0.5-1 mm smaller than the diameter of a sleeve hole in the center of the coil; the diameter of the leftmost end of the outer wall of the rubber sleeve is 1-2.5 mm larger than the diameter of the sleeve hole in the center of the wire coil.
Furthermore, in order to ensure the stability of the tool and facilitate the installation; the length of the rubber sleeve is not less than 1/12 and not more than 1/10 of the length of the mandrel.
The invention has the following technical effects:
(1) the tool is simple and reliable in structure and high in maturity; the winding and knotting of the metal sewing thread in the thread supply process can be prevented, and the problems of falling, local jumping and the like of the thread coil are prevented from occurring, so that the thread supply efficiency of the tool is ensured.
(2) The anti-winding thread supply device for the metal sewing thread can realize continuous thread supply, and has high efficiency and stable thread supply.
(3) The anti-winding thread supply of the metal sewing thread of the invention can be used for thread coils with different specifications.
