Detailed Description
The invention provides a needle selecting mechanism of a double-sided jacquard, which is used for making the purposes, technical schemes and effects of the invention clearer and more definite, and the invention is further described in detail below by referring to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Referring to fig. 2 to 6, the present invention provides a needle selecting mechanism of a double-sided jacquard. In practical application, the upper needle selecting mechanisms and the lower needle selecting mechanisms are respectively in annular arrangement on the double-sided jacquard, and the upper needle selecting mechanisms and the lower needle selecting mechanisms are mainly arranged in different installation orientations relative to the lower needle selecting mechanisms due to the same structural principle of the upper needle selecting mechanisms and the lower needle selecting mechanisms, so that the upper needle selecting mechanisms and the lower needle selecting mechanisms are mainly described by a group of lower needle selecting mechanisms.
Referring to fig. 2 and 3, the needle selecting mechanism of the double-sided jacquard includes a lower needle selecting mechanism and an upper needle selecting mechanism, the lower needle selecting mechanism includes a first needle selector 14, a first jacquard piece 13, a first jack 12 and a first knitting needle 11, the upper needle selecting mechanism includes a second needle selector 24, a second jacquard piece 23, a second jack 22 and a second knitting needle 21, the top end of the first jack 12 is connected with the bottom end of the first knitting needle 11, the first jacquard piece 13 is opposite to the first needle selector 14, and a protrusion 132 is disposed on the side of the first jacquard piece 13 away from the first needle selector for propping against one side of the first jack 12; the outward end (right end in view of fig. 2) of the second jack 22 is connected to the inward end (left end in view of fig. 2) of the second knitting needle 21, the second jacquard sheet 23 is disposed opposite to the second needle selector 24, and a protrusion 232 is disposed on the side of the second jacquard sheet 23 away from the second needle selector 24 for abutting against the side of the second jack.
For ease of understanding, the lower 191 and upper 291 syringes of the double-sided jacquard are schematically depicted in FIG. 2. The term "inwardly" as used herein refers to the direction toward the interior of the lower cylinder 191 of the double-sided jacquard machine (the left side of the lower cylinder being the interior thereof in the view of fig. 2), and "outwardly" is the opposite direction to the above-described "inwardly", and is intended to be illustrative, not limiting of the present invention.
Compared with the prior art, in the double-sided jacquard provided by the invention, the first jacquard sheet and the first needle jack are arranged in parallel, so that the installation height occupied by the lower needle selecting mechanism is reduced, and the size of a lower needle cylinder of the double-sided jacquard is correspondingly reduced; similarly, the installation size of the upper needle selecting mechanism in the horizontal direction is reduced, so that the size of an upper needle cylinder of the double-sided jacquard is correspondingly reduced; thereby making the structure of the double-sided jacquard more compact. In addition, when selecting and not selecting needles, the first jacquard sheet moves linearly in the horizontal direction, and the second jacquard sheet moves linearly in the vertical direction (the movement principle will be described in detail later), so that the needle selection is more stable and accurate, and the knitting quality is provided.
Fig. 3 shows the structure of the first jacquard sheet and the second jacquard sheet in the present invention, and since the first jacquard sheet 13 and the second jacquard sheet 23 have the same structure (different mounting orientations), only the structure of the first jacquard sheet and the second jacquard sheet can be represented by fig. 3, and drawings of the second jacquard sheet are not repeated. Further, as can be seen from fig. 3, the first jacquard sheet and the second jacquard sheet respectively include a rectangular body, one side of the rectangular body is provided with a plurality of needle selecting teeth 131, and the other side of the rectangular body is provided with a protrusion 132. As can be seen from fig. 2, in practice, the teeth of the first jacquard sheet face the first selector and the teeth of the second jacquard sheet face the second selector. Through this setting for the simple structure of jacquard weave piece, length is shorter, not only is convenient for make, has saved the installation space again.
Referring to fig. 2 and 3, further, the protrusions 132 of the first jacquard sheet and the protrusions 232 of the second jacquard sheet are arc-shaped protrusions. By arranging the arc-shaped bulges, the first needle jack or the second needle jack always props against the corresponding arc-shaped bulges when rotating. And the rolling friction is adopted between the first jack or the second jack and the corresponding arc-shaped bulge, so that the abrasion loss is greatly reduced.
Referring to fig. 2 and 3, further, the protrusion 132 of the first jacquard sheet is disposed at the middle part of the first jacquard sheet 13 in the length direction; the protrusions 232 of the second jacquard sheet are provided at the middle part of the second jacquard sheet 23 in the length direction.
With continued reference to fig. 3, for convenience of processing, the first jacquard sheet is symmetrically arranged along the horizontal axis, that is, the arc-shaped protrusions of the first jacquard sheet are arranged in the middle of the first jacquard sheet in the height direction (i.e., the length direction); each needle selecting tooth of the second jacquard sheet is symmetrically arranged at two sides of the horizontal axis, and two limiting grooves of the first jacquard sheet are symmetrically arranged at two sides of the horizontal axis; the second jacquard pieces are symmetrically arranged along the vertical axis, namely the arc-shaped bulges of the second jacquard pieces are arranged at the middle parts of the second jacquard pieces in the length direction; each needle selecting tooth of the second jacquard sheet is symmetrically arranged on two sides of the vertical axis, and two limiting grooves of the second jacquard sheet are symmetrically arranged on two sides of the vertical axis.
Further, as shown in fig. 3, two ends of the first jacquard sheet 13 on the side where the needle selecting teeth 131 are disposed are respectively provided with a limiting groove 133; the second jacquard sheet is provided with a limiting groove at each of the two ends of the side provided with the needle selecting teeth (the second jacquard sheet is still shown in fig. 3). When the device is actually applied to a double-sided jacquard, when the two limit grooves of the first jacquard sheet and the second jacquard sheet are matched with the corresponding limit rods on the double-sided jacquard (the limit rods 193 corresponding to the first jacquard sheet are shown in fig. 5), the limit position of the first jacquard sheet moving towards the first needle selector and the limit position of the second jacquard sheet moving towards the second needle selector can be limited; the first jacquard sheet and the second jacquard sheet are respectively positioned between the first needle selector and the second needle selector at proper positions so as to meet the requirements of normal needle selection. Although the limiting groove shown in the drawings is a U-shaped groove, the present invention is not limited to the specific shape of the limiting groove, and is not limited to the shape of the cross section of the corresponding limiting rod (such as a circle, a square, etc.).
Referring to fig. 5, in order to further ensure that the first jacquard sheet can move in parallel along the horizontal direction and the second jacquard sheet can move in parallel along the vertical direction (i.e., move in a straight line) during needle selection, the lower needle selecting mechanism further comprises a first syringe insert 15 for guiding the first jacquard sheet 13, the first needle jack 12 and the first knitting needle 11; the upper needle selection mechanism further comprises a second cylinder insert (not shown in the figures) for guiding the second jacquard, the second jack and the second needles. Since the first syringe insert and the second syringe insert have the same structural principle, only the first syringe insert is shown in fig. 5. The view angle of the drawing only observes one first needle cylinder inserting piece, but in actual application, a plurality of first needle cylinder inserting pieces are annularly arranged along the lower needle cylinder, a plurality of second needle cylinder inserting pieces are annularly arranged along the upper needle cylinder, when the needle selecting mechanism moves, a first jacquard piece, a first needle jack and a first knitting needle in each group of the lower needle selecting mechanism move in the gap between two adjacent first needle cylinder inserting pieces, and a second jacquard piece, a second needle jack and a second knitting needle in each group of the upper needle selecting mechanism move in the gap between two adjacent second needle cylinder inserting pieces, so that the first jacquard piece and the second jacquard piece are respectively in linear movement, and the first needle jack, the first knitting needle jack and the second knitting needle are correspondingly guided, and the needle selecting precision is improved.
Further, positioning grooves (the same as the position of the reference numeral 193 in fig. 5) are respectively arranged at the limiting grooves corresponding to the first jacquard piece on the first needle cylinder inserting piece; and the limiting grooves of the second needle cylinder inserting sheet corresponding to the second jacquard sheet are also respectively provided with positioning grooves (not shown in the figure). The corresponding limiting rods penetrate through the positioning grooves, so that the mounting positions of the first syringe inserting piece and the second syringe inserting piece are positioned.
Referring to fig. 2, the butt 1201 of the first jack 12 faces the first selector 14 and is located below the bottom end of the first jacquard sheet 13; the butt 2201 of the second jack 22 faces the second selector 24 and is located inside the inward end of the second jacquard sheet 23. By the arrangement, the first jack is convenient to not interfere with the first jacquard sheet in the moving process, and the second jack is convenient to not interfere with the second jacquard sheet in the moving process.
The present invention is not limited to the first jack, the first knitting needle, since the point of the invention is not present here, but the basic structure of the first jack is described below for the sake of easy understanding of the present invention. Referring to fig. 6, the first needle 11 is provided with a butt 1101 at the bottom, a hook 1102 at the top, and a needle leaf 1103 for guiding rotatably. The second needle is identical in construction (mounting orientation) to the first needle and is not described in detail herein.
The present invention is also not limited to how the top end of the first jack is connected with the bottom of the first knitting needle, and how the outward end of the second jack is connected with the inward end of the second knitting needle, because the connection is already achieved in the prior art (for example, in the patent of application publication CN 103696114 a). Of course, for ease of understanding, the connection of the first jack and the first needle is also provided herein.
Referring to fig. 6, a first hook 121 is disposed at the top end of the first jack 12, and a first groove 122 is disposed below the first hook; the bottom of the first knitting needle is provided with a second hook head 112 and a second groove 111; the first hook head 121 may be inserted into the second groove 111 and may rotate with respect to the second groove 111, and the second hook head 112 may be inserted into the first groove 122. The first recess 122 and the first hook 121 are provided on the side of the first jack facing the first selector, while the second recess 111 and the second hook 112 are provided on the side of the first needle facing away from the first selector. Through setting up the cooperation of first recess and second gib head, and the cooperation of first gib head and second recess, realized that first jack top and first knitting needle bottom are connected steadily, can upwards or drive first knitting needle motion downwards, the first gib head of first jack also can take place to rotate for first recess to satisfy jack and possess "select needle" and "not select needle" two states (the theory of operation that will describe "select needle" and "not select needle" in detail below).
Further, the profile of the first hook 121 includes a major arc; the profile of the second recess 111 also includes a major arc; the bottom side wall 1221 of the first recess includes a flat surface, and the bottom end of the second hook 112 also includes a flat surface. The arrangement ensures that the contact points of the first hook head and the second groove are always tangent, so that the first hook head receives smaller friction force when rotating relative to the second groove; and the bottom wall of the first groove bottom and the bottom end of the second hook head all comprise a plane, so that when the first needle jack moves in a vertical mode, the connection between the first groove and the second hook head is more stable, and the first knitting needle is ensured to stably do vertical movement. The contour of the first hook and the contour of the second groove refer to the contour of the first hook and the contour of the second groove in the front view of the jack and the knitting needle, because the first jack and the first knitting needle are integrally formed as a sheet-like member. Since the connection relationship between the second jack and the second knitting needle is similar to the connection relationship between the first jack and the first knitting needle (only the mounting orientation is different), the connection relationship between the second jack and the second knitting needle will not be described here again.
The present invention accordingly provides a double-sided jacquard machine, which is different from the prior art in that it comprises the aforementioned needle selection mechanisms, i.e. several sets of lower needle selection mechanisms and upper needle selection mechanisms are evenly arranged along the lower needle cylinder and the upper needle cylinder, respectively. Because other components of the double-sided jacquard (such as a frame, a lower needle cylinder, an upper needle cylinder and the like) are all arranged conventionally, the details are not repeated here.
Since the lower needle selecting mechanism and the upper needle selecting mechanism have the same working principle (only the difference in mounting orientations), the working principle is described below by taking the following needle selecting mechanism as an example (see fig. 4):
(1) The needle selecting knife 141 of the first needle selector 14 swings upward to act on the needle selecting teeth 131 of the first jacquard sheet of the same stage, pushes the first jacquard sheet to move linearly inward, and the first jacquard sheet 13 pushes the first jack 12 by the protrusion 132, so that the first jack 2 rotates relative to the first knitting needle 1 (the first jack rotates clockwise as shown in the view of fig. 4), so that the butt 1201 at the lower part of the first jack leaves the track 1921 of the first jack cam 192, thereby forming the state shown in fig. 4, that is, the first jack does not take part in operation, and accordingly, the first knitting needle connected with the first jack does not take part in operation, thereby realizing "needle non-selection", that is, the first knitting needle of "needle non-selection" does not knit.
(2) "Needle selecting", the needle selecting knife 141 of the first needle selector 14 swings downward, so that the needle selecting teeth on the first jacquard sheet are not acted on, the lower part of the first jack 2 moves in the direction of the needle selector (rightward in view of fig. 4) under the action of the reset cam (not shown), and at the same time, the first jack 12 pushes the first jacquard sheet 13 to move horizontally; the heel 1201 at the lower part of the first jack enters the track 1921 of the needle jack cam, i.e. the first jack moves up and down along with the track 1921 on the first needle jack cam and drives the corresponding first knitting needle to move up and down, so that the "needle selection", i.e. the knitting of the first knitting needle with the "needle selection" is realized.
The reset cam and the needle jack cam mentioned in the working principle are conventional components in the jacquard, the structural principle is not repeated herein, and the reset cam is not shown in the drawing.
Because the upper needle selecting mechanism and the lower needle selecting mechanism have the same structural principle, the generated technical benefits are the same.
As can be seen from the foregoing description, the beneficial effects of the present invention include at least: (1) The first needle jack and the first jacquard sheet are arranged in parallel, so that the occupied height of the lower needle selecting mechanism in the vertical direction is reduced; the second jack and the second jacquard sheet are arranged in parallel, so that the installation size occupied by the upper needle selecting mechanism in the horizontal direction is reduced; therefore, the whole structure of the double-sided jacquard is more compact, and the manufacturing cost is reduced. (2) In the process of needle selection or non-needle selection, the first jacquard sheet and the second jacquard sheet are in linear motion, so that needle selection cutters of the first needle selector and the second needle selector can accurately act on needle selection teeth (3) of the corresponding first jacquard sheet or second jacquard sheet, and the first jacquard sheet does not cause error accumulation in the vertical direction because the first jacquard sheet is in horizontal linear motion; since the second jacquard sheet is vertically rectilinear, the second jacquard sheet does not cause error accumulation in the horizontal direction. (4) Because the first jacquard sheet and the second jacquard sheet do not rotate around a groove on the lower needle cylinder or the upper needle cylinder as in the prior art, the bottoms of the first jacquard sheet and the second jacquard sheet do not generate rotation friction with the lower needle cylinder or the upper needle cylinder, and the bottoms of the first jacquard sheet and the second jacquard sheet are not worn to reduce the needle selecting precision. (5) The connection between the first jacquard sheet and the first jack is simpler (i.e. by being abutted by the protrusions); the connection between the second jacquard piece and the second needle jack is simpler, so that the structures of the first jacquard piece and the second jacquard piece are simpler, and a groove for connecting the first needle jack and a groove for connecting a reset triangle are not required to be arranged at the top of the first jacquard piece as in the prior art; as a preferred solution, the first jacquard sheet and the second jacquard sheet can be designed into symmetrical structures, and the structures of the first jacquard sheet and the second jacquard sheet are further simplified.
It should be noted that, although the first needle selector and the second needle selector shown in the drawings are all 12-knife electromagnetic needle selectors, the invention is not limited to the number of needle selectors of the needle selectors, because no matter the 8-knife electromagnetic needle selector, the 12-knife electromagnetic needle selector or even the 16-knife electromagnetic needle selector is adopted, the essence of the technical scheme of the invention is not changed.
It will be understood that equivalents and modifications will occur to those skilled in the art based on the present invention and its spirit, and all such modifications and substitutions are intended to be included within the scope of the present invention.
