Description

Glove knitting machine triangle system

Technical Field

The invention relates to the field of glove machines, in particular to a glove machine triangle system.

Background

The basic structure of the computerized glove knitting machine is as follows: a front needle bed and a rear needle bed are arranged between the left base and the right base, movable knitting needles are arranged in needle grooves of the needle beds, triangular bottom plates are arranged on split front and rear machine heads, and the triangular bottom plates transversely move left and right along with the machine heads; because various triangles are arranged on the triangle bottom plate, needle selection, needle lifting and needle cleaning actions are carried out through the interaction between each triangle and the butt of a knitting needle (combined needle), and various knitting functions are completed.

The existing computerized glove knitting machine generally connects the front machine head and the rear machine head through a machine head connecting device, and is driven by a driving device to realize synchronous movement of the front machine head and the rear machine head.

However, when this type of glove knitting machine is operated, half of the front and rear hand pieces are in an idle state during one round trip, and knitting of the glove is not performed, so in 3 months of 2022, the patent CN114182422a disclosed in applicant Shi Xiaochuan, a solution is proposed, that is, the hand piece connecting device is eliminated, and the front and rear hand pieces are controlled by a servo motor respectively, so that the glove knitting machine can be knitted during the round trip operation of the front and rear hand pieces, and the purported functional core technology is as follows: [ D1 Specification 0045 ]

The front guide needle machine head and the rear guide needle machine head are independently driven by two servo motors, (other common glove machines are all driven by one motor), and the front guide needle machine head and the rear guide needle machine head can be driven by one motor and can be converted by a mechanical structure to realize the conversion of dislocation movement and parallel movement of the front guide needle machine head and the rear guide needle machine head;

2. each yarn nozzle is also independently driven by an independent stepping motor or a servo motor;

3. the needle lifting cams of the front and rear needle guide heads can push the knitting needles on the needle bed when moving in the left and right directions, and the descending amplitude of the knitting needles is adjusted. "

However, the applicant considers that the front servo motor and the rear servo motor are used for realizing differential operation, so that the front guide needle head and the rear guide needle head are driven to do differential operation or synchronous reciprocating motion, the control precision requirement on the two servo motors is high (the market between the differential and the synchronous is required to be switched), the debugging difficulty is high, and the maintenance is inconvenient.

Therefore, the applicant applied for a glove knitting process, CN117026490a, in the 09 th year of 2023, in a manner of synchronous operation of multiple systems, for achieving the above object, wherein the related triangular system (triangular system includes a triangular base plate and various types of triangles) is shown in fig. 1, an integrated upper middle triangle 001 (actually functioning as two upper middle triangles of a common glove knitting machine, two lower middle triangles are respectively disposed on the left and right sides thereof), two adjacent rubber triangle 002 (for rubber knitting) are disposed under the upper middle triangle 001, and a needle raising triangle 003 disposed on both sides of the rubber triangle, and two density triangles (also referred to as stitch triangles) 004 are disposed on both sides of the upper middle triangle.

After a period of production test, the applicant has improved the above structure, as shown in fig. 2, two needle raising cams (011, 012) are staggered and overlapped, and two rubber band cams (013, 014) in the middle are arranged on the left and right sides, so as to reduce the size of the whole cam system, shorten the needle running track of the knitting needle, and make knitting more efficient: the knitting efficiency can be improved by starting the knitting needle on the cam base plate on the other side already when the knitting needle on the cam base plate on the one side has not completed knitting (this principle is described in detail in the previous patent 202311509297.X filed by the applicant at 2023.11.14 and is not extended any more).

In order to adapt to the scheme and ensure the original knitting function, density triangles on two triangle bottom plates are improved: the density triangle side edges (015, 016) on the two sides of the first triangle bottom plate are made into a swinging structure, and are in an unfolding state as shown in the density triangle 015 in fig. 2 during normal knitting; when it is necessary to knit an elastic thread, as shown in fig. 2, the elastic thread triangle 014 is needle-punched to shift the swing portion of the elastic thread triangle 016 to the closed state. The design not only ensures that the rubber band triangle from the middle to the two sides has the installation position, but also reduces the needle track (part space of the density triangle is borrowed, and the needle pressing triangle 018 and the needle protecting triangle 019 are matched).

Correspondingly, a density triangle 017 located in the middle on the other second triangle bottom plate is made into a left-right swinging structure for matching with staggered and overlapped needle lifting triangles, and the original functions of the density triangle are unchanged on the premise of ensuring that the stroke is shortened (refer to the prior application 202323063331.3 of the applicant).

However, in the practical production and application process, the applicant found that when the density cams (0015, 0016) in fig. 2 are in the unfolded state, the butt of the knitting needle may be embedded into the slit after being unfolded under the action of the tension of the yarn, so that the needle running resistance of the knitting needle may be easily increased, and the stitch may be damaged.

Therefore, the inventor further research and develop a glove knitting machine triangle system, which is generated by the scheme.

Disclosure of Invention

The invention aims to provide a glove knitting machine triangle system which solves the technical problems in the background art on the premise of keeping the double-sided knitting function of a glove knitting machine.

In order to achieve the above object, the technical scheme of the present invention is as follows:

a glove knitting machine triangle system comprises a first triangle bottom plate, wherein the first triangle bottom plate comprises a first upper middle mountain triangle arranged in the middle, first density triangles are respectively arranged on two sides of the first upper middle mountain triangle, and corresponding rubber band triangles are respectively arranged on the side edges of the first density triangles; the first density triangle comprises a telescopic part, the telescopic part is positioned at the side edge of the body and can extend or retract relative to the body: when the telescopic part is in an extending state, the density triangle works normally, and when the telescopic part is in a retracting state, an elastic knitting needle passage is formed between the elastic triangle and the first density triangle.

In the prior patent of the applicant, the swinging part of the first density triangle is used for realizing the function, but the problem that the butt rises when the knitting needle walks is solved, after the technical scheme of the application is adopted, the bottom of the telescopic part is a continuous boundary, the problem that the butt walks when the knitting needle is pressed is avoided, and a channel can be yielded when the elastic band is knitted through the movement of the telescopic part, so that the function required by the applicant in a series of improvements can be realized.

Further, the retraction of the telescopic part is achieved by the action of the knitting needle: one side of the telescopic part, which is close to the rubber band triangle, is an inclined plane, and when the rubber band is knitted, the butt of the knitting needle enters along the inclined plane of the telescopic part and presses the telescopic part into the first triangle bottom plate.

The mode can omit a driving source for actively controlling the telescopic part, and the needle moving channel can be pressed out when the rubber band is knitted only by the pressure of the knitting needle.

Further, the extension of the telescopic part is achieved by a return spring arranged at the back side thereof.

When ordinary knitting is performed, the butt of the knitting needle runs from the body side of the first density triangle, and in the process, the telescopic part is always in an extending state under the action of the reset spring and cannot retract under the action of the butt.

Further, the telescopic part is positioned at the left side of the first triangular bottom plate, the left side of the inclined plane of the telescopic part is low, and the right side of the inclined plane of the telescopic part is high; the telescopic part is positioned on the right side of the first triangular bottom plate, and the inclined surface of the telescopic part is low on the right side and high on the left side.

Further, the needle lifting position of the rubber triangle positioned at the left side of the first triangle bottom plate is positioned at the left side, and the needle lifting position of the rubber triangle positioned at the right side of the first triangle bottom plate is positioned at the right side; the corresponding elastic triangle needle lifting direction on the second triangle bottom plate is opposite to the needle lifting direction of the elastic triangle on the first third triangle bottom plate.

Because the needle-moving process of the whole triangle bottom plate is more compact, in order to prevent the rubber band triangles on the front triangle bottom plate and the rear triangle bottom plate from conflicting with each other, the needle-moving directions of the rubber band triangles on the two triangle bottom plates are set to be opposite, and the normal work of the rubber band triangles is realized by utilizing the back and forth movement of the machine head.

Further, the second triangular bottom plate comprises a swing density triangle and an auxiliary density triangle, the swing density triangle is positioned between the two second upper middle mountain triangles, when the lower end of the swing density triangle swings leftwards, the end part of the swing density triangle is connected with the side end of the left auxiliary density triangle, and when the lower end of the swing density triangle swings rightwards, the end part of the swing density triangle is connected with the side end of the right auxiliary density triangle.

This arrangement is also intended to prevent the butt of the knitting needle from running into the space between the auxiliary density cam and the oscillating density cam.

Further, the swing density triangle and the auxiliary density triangle are arranged in the respective sliding grooves, and the swing density triangle and the auxiliary density triangle are linked.

Further, the first triangle bottom plate comprises two needle lifting cams arranged below the first upper middle mountain triangle, and the two needle lifting cams are partially overlapped to enable needle moving oblique sides of the two needle lifting cams to form staggering.

After the scheme is adopted, compared with the prior art, the invention has the following advantages:

on the premise of optimizing the double-sided knitting of the glove knitting machine, the structure of the positions of the density cams and the rubber band cams is further simplified, so that the glove knitting efficiency of the rubber band of the glove can be improved, the control of the density cams on the knitting needle butt is not influenced, and the production efficiency of the glove knitting machine is optimized finally.

Detailed Description

The invention will be further described with reference to the drawings and the specific examples.

The prior patent application provided by the background art can know that the existing density triangle moves up and down relative to the triangle bottom plate to control the knitting size of the glove (i.e. the larger the size of the glove knitted by pressing the density triangle downwards), so that the person skilled in the art cannot or does not have power to independently set the density triangle to be in a front-back telescopic structure. The invention develops a triangle system based on the double-sided knitting of the glove, then optimizes based on the system, and solves the found technical problems in the optimizing process, thereby obtaining the technical conception of the invention, and the specific embodiments thereof are as follows:

as shown in fig. 3, a glove knitting machine triangle system includes a first triangle base plate 1 and a second triangle base plate 2, wherein:

the first triangular bottom plate 1 comprises a first upper middle mountain triangle 15, two first lower middle mountain triangles (151 and 152) are arranged below the first upper middle mountain triangle 15, two first needle raising triangles (16 and 17) which are partially overlapped and are formed by needle moving oblique sides are arranged between the first lower middle mountain triangles (151 and 152), and meanwhile, first density triangles (11 and 12) are respectively arranged on two sides of the first upper middle mountain triangle 15. Namely, the most basic knitting process of the glove knitting machine is that after the butt of a knitting needle is selected, the knitting needle is started from a needle starting cam, the hooked yarn is lifted along a needle passage between an upper mountain cam and a lower mountain cam, then the knitting yarn is lowered, and finally the pulling-down amplitude of a loop is controlled through a density cam; the staggered needle lifting cams can make the lifting time and space of the front needle bed knitting needle and the rear needle bed knitting needle more compact in double-sided knitting so as to improve the knitting efficiency.

Unlike the previous patents, the first density cams (11, 12) comprise a body (111, 112) and telescopic parts (101, 102), the telescopic parts (101, 102) being located at the sides of the respective body (111, 112) and being capable of extending or retracting with respect to the body, the telescopic parts (101, 102) being inclined at the side close to the rubber band cams, the butts of the needles entering along the inclined surfaces of the telescopic parts (101, 102) and pressing the telescopic parts (101, 102) into the first cam base plate 1 when the rubber band knitting is performed. As shown in fig. 4 and 5, the telescopic part 101 located on the left side of the first cam base plate 1 has a lower left side and a higher right side of the inclined plane 1011, and the knitting needle can press the telescopic part into the cam base plate when entering from the left side; the telescoping portion 102 located on the right side of the first cam plate 1 has a lower right side and a higher left side, and the telescoping portion is pushed into the cam plate when the knitting needle is inserted from the right side.

The resetting of the telescopic parts (101, 102) is realized by a reset spring arranged on the back surface of the telescopic parts; when ordinary knitting is performed, after the needle passage of the first upper mountain triangle 15 descends, the butt of the knitting needle descends along the side edge of the first density triangle (11, 12), the butt of the knitting needle runs from the body side of the first density triangle (11, 12), and in the process, the telescopic parts (101, 102) are always in an extending state under the action of the reset spring and can not retract under the action of the butt. Taking fig. 5 as an example, in the process from the low point 113 of the body to the low point 103 of the telescopic part, the butt of the knitting needle continuously receives the action of the telescopic part and does not move upwards, namely, the density triangle is in a normal working state.

Meanwhile, the needle lifting position of the first rubber triangle 13 positioned at the left side of the first triangle bottom plate 1 is positioned at the left side, and the needle lifting position of the first rubber triangle 14 positioned at the right side of the first triangle bottom plate 1 is positioned at the right side; the corresponding elastic triangle needle lifting direction on the second triangle bottom plate 2 is opposite to the needle lifting direction of the elastic triangle on the first third triangle bottom plate, the needle lifting directions of the elastic triangles on the two triangle bottom plates are set to be opposite, and the normal work of the elastic triangle is realized by the back and forth movement of the machine head.

The needle pressing cams 18, needle protecting cams 19 on the first cam base are identical in structure and function to those of the prior patent and are not unfolded here.

The second triangular bottom plate 2 comprises a swing density triangle 21 and auxiliary density triangles (201, 202), the swing density triangle 21 is positioned between two second upper middle mountain triangles, the swing density triangle 21 and the auxiliary density triangles (201, 202) are arranged in respective sliding grooves, and the swing density triangle 21 and the auxiliary density triangles (201, 202) are linked. When the lower end of the swing density triangle 21 swings to the left, the end thereof is connected to the side end of the left auxiliary density triangle 201, and when the lower end of the swing density triangle 21 swings to the right, the end thereof is connected to the side end of the right auxiliary density triangle 202. This arrangement is also to prevent the butt of the knitting needle from moving into the gap between the auxiliary density cams (201, 202) and the rocking density cam 21.

The foregoing is only specific embodiments of the present invention, and words such as "upper, lower, left, right, middle" and the like "related to the present invention are merely used by way of reference, not to be construed as limiting, and any insubstantial modifications made by the present invention shall fall within the scope of the invention.
