Description

Technical Field

[0001] The utility model relates to the technical field of weaving equipment, and more specifically, to a double-driven knitting strip. Background Art

[0002] The elastic sinker is a sinker with an elastic presser foot. Like the traditional sinker, it is driven to retract and retract through the Sink triangle of the Sink device in the flat knitting machine to determine whether it participates in the yarn pressing work. When the Sink triangle drives the elastic sinker to retract, it needs to overcome the rebound force of its elastic presser foot to avoid losing coordination with the elastic sinker.

[0003] Most of the existing Sink triangle groups are controlled by a driving motor. The Sink strips are not flexible enough to complete a variety of complex weaving movements, and the space limitations of the weaving mountain board and the transmission structure between the various components need to be considered.

[0004] In view of the above-mentioned deficiencies of the known existing Xinke strips, the applicant adheres to the spirit of research innovation and excellence, combines production practice, and uses professional and scientific methods to propose a practical solution, and therefore files this application. Summary of the invention

[0005] In order to overcome at least one defect of the prior art described above, the utility model provides a double-drive signal strip, which controls the signal cam and the reset cam to operate independently through two sets of drive motors, thereby realizing a variety of complex knitting actions.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions: a dual-drive Sink bar, a reset drive motor, a Sink drive motor, a Sink mother plate, a sinker reset triangle, a Sink triangle, a reset triangle, a reset slide plate, and a Sink slide plate. The front of the Sink mother plate is provided with a sinker reset triangle, a Sink triangle and a reset triangle. The Sink drive motor located on the back of the Sink mother plate drives the Sink gear row to move laterally through gears. The Sink slide plate is installed on the Sink gear row. The bearings on the Sink triangle move along the lower sliding groove on the Sink slide plate. The reset drive motor drives the reset gear row to move laterally through gears. The reset slide plate is installed on the reset gear row. The bearings on the reset triangle move along the upper sliding groove on the reset slide plate.

[0007] Specifically, a sinker reset triangle is arranged on the front side of the sinker motherboard, and the sinker reset triangle is divided into a left sinker reset triangle, a middle sinker reset triangle and a right sinker reset triangle. Sinker triangles are arranged on both sides of the middle sinker reset triangle, and sinker triangles are arranged on one side of the left sinker reset triangle and the right sinker reset triangle on both sides of the sinker motherboard. The two middle sinker reset triangles are arranged between the left sinker reset triangle and the right sinker reset triangle, and the left sinker reset triangle and the right sinker reset triangle are both half of the middle sinker reset triangle.

[0008] Specifically, the sinker reset triangle is provided with an upwardly protruding extension portion, which is used to abut the rear edge of the elastic sinker and is located below the sinker triangle. The extension portion adopts an arc transition, and the rear edge of the elastic sinker can slide on the plane.

[0009] Specifically, a group of reset triangles are provided between the signal triangles, and the group of reset triangles are divided into a left reset triangle and a right reset triangle. The signal triangle and the reset triangle both have an upper triangle and a lower triangle, and a needle path is formed between the upper triangle and the lower triangle for the elastic sinker needle butt to pass through.

[0010] Specifically, the back of the Sink motherboard is provided with at least one Sink skateboard seat, the Sink skateboard seat is provided with a limit groove for the displacement of the Sink skateboard, a limit protrusion in the limit groove, and a straight groove hole for the limit protrusion to slide on the reset skateboard, and the limit protrusion can be displaced back and forth in the straight groove hole.

[0011] Specifically, the back of the reset triangle and the sinker triangle are connected to the sinker key base plate through a key base plate slider, a longitudinal slot is set on the sinker motherboard, the key base plate slider moves up and down along the longitudinal slot, the sinker key base plate is clamped on the back of the sinker motherboard, the bearing is set on the sinker key base plate, and the bearing is installed on the sinker key base plate through a bearing pin.

[0012] Specifically, the reset slide plate is also provided with an air avoidance groove, the transversely arranged air avoidance groove is connected to the upper sliding grooves on the left and right sides, the upper sliding groove and the lower sliding groove are in a Z-shaped step shape, and a U-shaped air avoidance groove is provided at the bottom of the Xinke slide plate.

[0013] Specifically, the upper and lower ends of the back side of the Xinke skateboard seat are like back protrusions to form limit blocks, the upper limit block is located in the air avoidance groove, and the lower limit block is located in the U-shaped air avoidance groove. The air avoidance groove and the U-shaped air avoidance groove are designed according to the positions of the limit blocks to avoid unnecessary collisions.

[0014] Compared with the prior art, the beneficial effects are: a reset drive motor and a Xinke drive motor are arranged on the back of the Xinke motherboard, and the displacement of each triangle is controlled separately by the reset slide plate and the Xinke slide plate. When the reset slide plate and the Xinke slide plate are in lateral displacement, the Xinke triangle and the reset slide plate are displaced along the sliding groove on the slide plate through the bearing, thereby realizing the longitudinal displacement of the Xinke triangle and the reset slide plate, and completing the actions of needle selection and needle clearing of the mountain board. Since two motors are used for separate control, the Xinke triangle and the reset slide plate can be independently controlled, thereby completing more complex weaving actions.

[0020] The drawings are only for illustrative purposes and cannot be construed as limiting the present invention. To better illustrate the present embodiment, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are only for illustrative purposes and cannot be construed as limiting the present invention.

[0021] like Figures 1 to 5As shown, a double-driven Sink bar, a reset drive motor 1, a Sink drive motor 2, a Sink motherboard 3, a sinker reset triangle 4, a Sink triangle 5, a reset triangle 6, a reset slide plate 7, and a Sink slide plate 8. The front side of the Sink motherboard 3 is provided with a sinker reset triangle 4, a Sink triangle 5 and a reset triangle 6. The Sink drive motor 2 located on the back side of the Sink motherboard 3 drives the Sink gear row 81 to move horizontally through gears. The Sink slide plate 8 is installed on the Sink gear row 81. The bearing on the Sink triangle 5 moves along the lower sliding groove 82 on the Sink slide plate 8. The position driving motor 1 drives the reset gear row 71 to move horizontally through gears. The reset slide plate 7 is installed on the reset gear row 71. The bearing on the reset triangle 6 moves along the upper sliding groove 72 on the reset slide plate 7. Under the action of the stepped upper sliding groove 72 and the lower sliding groove 82, the reset triangle 6 and the signal triangle 5 can be driven to move up and down respectively, and the elastic sinker 9 is driven to extend or retract itself through the needle butt 91 of the elastic sinker 9. If the elastic sinker 9 is in the extended state, the sinker reset triangle 4 can be used to participate in the corresponding yarn pressing work.

[0022] In the above scheme, a sinker reset triangle 4 is provided on the front of the sinker motherboard 3, and the sinker reset triangle 4 is divided into a left sinker reset triangle 41, a middle sinker reset triangle 42, and a right sinker reset triangle 43. Sinker triangles 5 are provided on both sides of the middle sinker reset triangle 42, and sinker triangles 5 are provided on one side of the left sinker reset triangle 41 and the right sinker reset triangle 43 located on both sides of the sinker motherboard 3. The sinker reset triangle 4 is provided with an upwardly protruding extension 44, and the extension 44 for abutting the rear edge of the elastic sinker 9 is located below the sinker triangle 5, and the extension 44 can support the raised elastic sinker 9.

[0023] As described above, the elastic sinker 9 itself has an elastic presser foot 92 for providing yarn pressing pressure. The elastic presser foot 92 is specifically pressed and deformed by cooperating with the plug plate of the needle plate assembly (the rest of the horizontal knitting machine, not shown in the figure). When the downward-moving sinker triangle 5 wants to retract the elastic sinker 9 through driving cooperation, the elastic presser foot 92 will seek a rebound opportunity due to the deformation. If it is not restricted, the rebound force will cause the needle butt 91 of the elastic sinker 9 to lose the matching relationship with the sinker triangle 5, that is, the elastic sinker 9 cannot be moved. Therefore, the above-mentioned reset triangle 6 is also formed with an extension portion 44 in the direction of the sinker triangle 5, and the thickness of the extension portion 44 will be greater than the needle track depth of the sinker triangle 5 to a certain extent. The signal triangle 5 moves down to a lower position, and because the machine head moves horizontally and cooperates with the needle butt 91 of the elastic sinker 9, the rear edge of the elastic sinker 9 will continue to press against the front side of the extension part 44. At this time, the signal triangle 5 and the extension part 44 restrain the elastic sinker 9 in both directions, so that its elastic pressure foot 92 cannot rebound, and the elastic sinker 9 can therefore be normally pulled back.

[0024] In the above scheme, a group of reset triangles 6 are provided between the signal triangles 5, and the group of reset triangles 6 are divided into a left reset triangle 61 and a right reset triangle 62. The signal triangles 5 and the reset triangles 6 both have an upper triangle and a lower triangle, and a needle path for the needle butt 91 of the elastic sinker 9 to pass through is formed between the upper triangle and the lower triangle. When the signal triangle 5 is displaced upward, the elastic sinker 9 is pushed upward; if reset is required, the reset triangle 6 is displaced downward to reset the elastic sinker 9.

[0025] In the above scheme, at least one sink slide plate seat 100 is provided on the back of the sink motherboard 3, and the sink slide plate seat 100 is provided with a limit groove 101 for displacement of the sink slide plate 8, a limit protrusion 102 in the limit groove 101, and a straight slot hole 73 for the limit protrusion 102 to slide on the reset slide plate 7. The straight slot hole 73 is used to limit the lateral displacement distance of the limit protrusion 102. The back of the reset triangle 6 and the sink triangle 5 are connected to the sink key bottom plate 201 through the key bottom plate slider 200, and the sink motherboard 3 is provided with a longitudinal slot, and the key bottom plate slider 200 moves up and down along the longitudinal slot. The sink key bottom plate 201 is clamped on the back of the sink motherboard 3, and the bearing is provided on the sink key bottom plate 201, and the bearing 202 is installed on the sink key bottom plate 201 through the bearing pin.

[0026] In the above scheme, the reset slide plate 7 is also provided with an air avoidance groove 74, and the transversely arranged air avoidance groove 74 is connected to the upper sliding groove 72 on the left and right sides. The upper sliding groove 72 and the lower sliding groove 82 are in a Z-shaped step shape, respectively high and low positions, or even multiple positions, so as to control the displacement distance of the signal triangle 5 and the reset triangle 6. The bottom of the signal slide plate 8 is provided with a U-shaped air avoidance groove 83. The upper and lower ends of the back of the signal slide plate seat 100 are formed as a back protrusion to form a limit block 103. The upper limit block 103 is located in the air avoidance groove 74, and the lower limit block 103 is located in the U-shaped air avoidance groove 83. The U-shaped air avoidance groove 83 and the air avoidance groove 74 can avoid the displacement path of the upper and lower limit blocks 103 to avoid unnecessary collisions.

[0027] During operation, the reset drive motor 1 and the Xinke drive motor 2 control the rotation of the gears through the rotating shaft. The two gears are respectively meshed with the Xinke gear row 81 and the reset gear row 71. One motor controls one gear row to achieve independent transmission. When needle selection is required, the Xinke drive motor 2 is started to drive the Xinke gear row 81 to move, so that the Xinke slide plate 8 makes a left and right lateral linear displacement. During the displacement process, the bearing on the back of the Xinke triangle 5 will also move along the lower sliding groove 82 of the Xinke slide plate 8. The bearing will repeatedly move between the high and low positions of the lower sliding groove 82 to achieve the up and down displacement of the Xinke triangle 5 and complete the needle selection action of the mountain board. Similarly, the reset drive motor 1 also drives the reset triangle 6 to slide up and down through the same principle, thereby completing actions such as needle clearing. The two drive systems cooperate with each other to complete multiple actions of the weaving equipment and weave more similar fabrics.

[0028] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description, such as the use of two-system and three-system leading machine mountain boards. It is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the claims of the utility model.
