Description

Technical Field

[0001] The present invention belongs to the technical field of knitting machines, and particularly relates to a two-layer four-impeller full-spindle knotless net knitting device. Background Art

[0002] A knotless net is a net-like fabric without knots formed by the interweaving of net wires or strands of net wires. According to its structure, it is divided into warp-knitted net structure, braided net structure, twisted net structure, inserted-twist net structure, plain-woven net structure and formed net structure. The filaments in the net are connected to each other, and it has the advantages of uniform stress, tensile resistance, wear resistance, flat net body, impact resistance, etc. It is not only used for fishing operations, but also widely used in places such as safety protection and sports and leisure.

[0003] Currently, the knitting of knotless nets in China mainly relies on rapier looms and warp knitting machines. Rapier looms have problems of low production efficiency and uneven quality, and the fabric quality is greatly affected by mechanical precision; warp-knitted fabrics are formed by the loop knitting of chain stitches of yarns. The fabric has elasticity, the mesh size will fluctuate within a certain range, and the crimp of the yarn will cause some strength loss. Relatively speaking, for the knotless net produced by two-dimensional knitting technology, the yarn buckling in the fabric structure is small and the strength loss is smaller.

[0004] The closed knotless net knitting-winding-forming integrated equipment described in the patent CN110983614B can produce closed knotless knitting nets with small mesh and many nodules. The multi-layer three-dimensional radial knitting machine described in the patent CN112831909A adopts a multi-layer guide rail setting to meet the requirements of variable diameter and multi-layer reciprocating three-dimensional knitting. However, in the process of mutual transformation between the net feet and the net knots, it is very difficult to solve the problem of spindle interference, so full-spindle arrangement cannot be achieved. Summary of the Invention

[0005] The main object of the present invention is to propose a two-layer four-impeller full-spindle knotless net knitting device, which can effectively solve the problems in the background art.

[0006] To achieve the above object, the present invention is realized through the following technical solutions:

Every 4 impellers adjacent to each other in the circumferential and axial directions are defined as an impeller group. Then the 4n impellers form n impeller groups arranged circumferentially along the annular track panel. Each impeller group is provided with a bobbin holder in the notch of the impeller in the way of 8 occupied and 8 empty. A yarn carrier is sleeved on the upper part of the bobbin holder;

[0012] The inner surface of the annular track panel has a groove-shaped fixed bobbin holder track distributed crosswise in the axial and circumferential directions. The groove-shaped fixed bobbin holder track corresponds to the 4n impellers. The bobbin cutter at the lower part of the bobbin holder cooperates with the groove-shaped fixed bobbin holder track;

[0014] The surface of the track-changing turntable is provided with an intersecting bobbin holder track and a separating bobbin holder track. When the track-changing turntable is in the intersecting bobbin holder track, the axially adjacent groove-shaped fixed bobbin holder track and the circumferentially adjacent groove-shaped fixed bobbin holder track are communicated through the intersecting bobbin holder track. When the track-changing turntable is in the separating bobbin holder track, the axially adjacent groove-shaped fixed bobbin holder track and the circumferentially adjacent groove-shaped fixed bobbin holder track are not communicated;

[0019] A column of impeller gear transmission mechanisms b includes a first impeller single-shaft gear assembly and a second impeller single-shaft gear assembly arranged axially. Both the first impeller single-shaft gear assembly and the second impeller single-shaft gear assembly include an impeller short shaft sleeved with an impeller bearing and a second single-joint spherical bevel gear. One end of the impeller short shaft passing through the annular track panel and located inside the annular track panel is connected to the impeller, and the end located outside the annular track panel is connected to the second single-joint spherical bevel gear;

[0020] Two columns of impeller gear transmission mechanisms are alternately arranged in the abab manner.

The second single-joint spherical bevel gear of the first impeller single-shaft gear assembly simultaneously meshes with the inner gear of the double-joint spherical bevel gear in the same group, the second single-joint spherical bevel gear of the second impeller single-shaft gear assembly, and the inner gear of the double-joint spherical bevel gear in the adjacent group.

[0021] Preferably, the annular track panel and the spherical housing respectively have a number of first small holes and second small holes for the first impeller long shaft, the second impeller long shaft, and the impeller short shaft to pass through and be fixed, so as to fix the impeller gear transmission mechanism group between the annular track panel and the spherical housing.

[0022] Preferably, the n impeller gear transmission mechanism groups are driven by an impeller drive system. The impeller drive system includes a three-phase asynchronous motor, a motor reducer, a motor support plate, a motor spherical bevel gear, an intermediate spherical bevel gear, and a gear connecting shaft.

[0061] Embodiment, as Figure 1-11 shown, a two-layer four-impeller full-spindle knotless net weaving device includes a support frame 4, a spherical outer shell 2, a track transmission device 1, and a fabric guiding device 3. The spherical outer shell 2 is fixed on the support frame 4; the track transmission device 1 is fixed inside the spherical outer shell 2 and is coaxially arranged with the spherical outer shell 2.

[0062] Referring to Figure 3-4 , the track transmission device 1 includes an annular track panel 11. 4n impellers 12 are rotatably mounted on the inner surface of the annular track panel 11. The 4n impellers 12 are arranged in two layers. Every 4 impellers 12 adjacent in the circumferential and axial directions are defined as an impeller group (dotted part). Then the 4n impellers 12 form n impeller groups arranged along the circumference of the annular track panel 11. Referring to Figure 8, each impeller group is provided with a bobbin seat 13 at the notch of the impeller 12 in a way of 8 occupied and 8 empty. A yarn carrier is sleeved on the upper part of the bobbin seat 13, and the yarn carrier is used to provide the yarn for knitting the knotless net.

[0063] The inner surface of the annular track panel 11 has a groove-shaped fixed bobbin seat track 14 which is distributed crosswise along the axial direction and the circumferential direction. The groove-shaped fixed bobbin seat track 14 corresponds to the 4n impellers 12. The bobbin knife at the lower part of the bobbin seat 13 cooperates with the groove-shaped fixed bobbin seat track 14, and the bobbin knife provides guidance for the whole bobbin seat 13. When the impeller 12 rotates, the bobbin seat 13 moves in the groove-shaped fixed bobbin seat track 14.

[0064] 4n track-changing turntables 15 are rotatably installed on the groove-shaped fixed bobbin seat track 14. The track-changing turntables 15 are respectively located at the intersection points of the axially adjacent groove-shaped fixed bobbin seat tracks 14 in each impeller group and the intersection points of the circumferentially adjacent groove-shaped fixed bobbin seat tracks 14 of the impeller groups.

[0065] The surface of the track-changing turntable 15 is provided with an intersecting bobbin seat track and a separating bobbin seat track. When the track-changing turntable 15 is in the intersecting bobbin seat track, the axially adjacent groove-shaped fixed bobbin seat tracks 14 and the circumferentially adjacent groove-shaped fixed bobbin seat tracks 14 are communicated through the intersecting bobbin seat track, and the bobbin seat 13 can move between the groove-shaped fixed bobbin seat tracks 14 through the intersecting bobbin seat track. When the track-changing turntable 15 is in the separating bobbin seat track, the axially adjacent groove-shaped fixed bobbin seat tracks 14 and the circumferentially adjacent groove-shaped fixed bobbin seat tracks 14 are not communicated, and the bobbin seat 13 cannot move between the groove-shaped fixed bobbin seat tracks 14.

[0066] The fabric guiding device 3 is fixed in the middle of the track transmission device 1. The fabric guiding device 3 is used to control the yarn tension and assist in yarn traction, facilitating the knitting of the knotless net.

[0067] The annular track panel 11 of the present invention is spherical, making full use of the axial dimension to increase the number of impellers 12, and having a small floor area.

[0068] In a specific embodiment, referring to Figure 5-6 , it further includes n impeller gear transmission mechanism groups. The n impeller gear transmission mechanism groups are arranged circumferentially on the outer surface of the annular track panel 11, and one impeller gear transmission mechanism group corresponds to one impeller group.

[0069] One impeller gear transmission mechanism group includes a row of impeller gear transmission mechanisms a and a row of impeller gear transmission mechanisms b.

[0070] A set of impeller gear transmission mechanism a includes an axially arranged impeller double gear assembly 5 and an impeller single long shaft gear assembly 6. The impeller double gear assembly 5 includes a first impeller long shaft 52 sleeved with an impeller bearing and a double spherical bevel gear 51. One end of the first impeller long shaft 52 that passes through the annular track panel 11 and is located inside the annular track panel 11 is connected to the impeller 12, and the end located outside the annular track panel 11 is connected to the double spherical bevel gear 51. The impeller single long shaft gear assembly 6 includes a second impeller long shaft 62 sleeved with an impeller bearing and a first single spherical bevel gear 61. One end of the second impeller long shaft 62 that passes through the annular track panel 11 and is located inside the annular track panel 11 is connected to the impeller 12, and the end located outside the annular track panel 11 is connected to the first single spherical bevel gear 61.

[0071] A set of impeller gear transmission mechanism b includes an axially arranged first impeller single short shaft gear assembly 7 and a second impeller single short shaft gear assembly 8. Both the first impeller single short shaft gear assembly 7 and the second impeller single short shaft gear assembly 8 include an impeller short shaft 72 sleeved with an impeller bearing and a second single spherical bevel gear 71. One end of the impeller short shaft 72 that passes through the annular track panel 11 and is located inside the annular track panel 11 is connected to the impeller 12, and the end located outside the annular track panel 11 is connected to the second single spherical bevel gear 71.

[0072] Two sets of impeller gear transmission mechanisms are alternately arranged in the abab manner. The first single spherical bevel gear 61 meshes with the outer gear of the double spherical bevel gear 51 in the same group. The second single spherical bevel gear 71 of the first impeller single short shaft gear assembly 7 meshes with the inner gear of the double spherical bevel gear 51 in the same group, the second single spherical bevel gear 71 of the second impeller single short shaft gear assembly 8, and the inner gear of the double spherical bevel gear 51 in the adjacent group at the same time. Such a structure enables the impeller 12 gear transmission mechanism groups to be interconnected, that is, the impellers 12 are also interconnected, so that only one impeller drive system is required to drive the impellers 12 to rotate.

[0073] In a specific embodiment, the annular track panel 11 and the spherical housing 2 respectively have a number of first small holes and second small holes for the first impeller long shaft 52, the second impeller long shaft 62, and the impeller short shaft 72 to pass through and be fixed, so as to fix the impeller gear transmission mechanism group between the annular track panel 11 and the spherical housing 2.

[0074] In a specific embodiment, refer to Figure 7, the n impeller gear transmission mechanism groups are driven by an impeller drive system 9, and the impeller drive system 9 includes a three-phase asynchronous motor 91, a motor reducer 92, a motor support plate 93, a motor spherical bevel gear 96, an intermediate spherical bevel gear 95, and a gear connecting shaft 94. The motor support plate 93 is fixed on the annular track panel 11. The three-phase asynchronous motor 91 is connected to and fixed inside the motor support plate 92. The output shaft of the motor reducer 92 extends outside the motor support plate 93 and is connected to the motor spherical bevel gear 96. The gear connecting shaft 94 is arranged outside the motor support plate 92. The intermediate spherical bevel gear 95 is connected to the gear connecting shaft 94. The motor spherical bevel gear 96 meshes with the intermediate spherical bevel gear 95. The intermediate spherical bevel gear 95 also meshes with the outer gear of the double spherical bevel gear 51 of an impeller double gear assembly. When the three-phase asynchronous motor 91 and the motor speed reducer 92 rotate, they drive the motor spherical bevel gear 96 to rotate. The motor spherical bevel gear 96 then drives the intermediate spherical bevel gear 95 to rotate. Finally, the intermediate spherical bevel gear 95 drives the double spherical bevel gear 51 of an impeller double gear assembly to rotate, so as to make each impeller 12 rotate.

[0075] In a specific embodiment, referring to Figure 3 , the orbit-changing turntable 15 is driven by an orbit-changing turntable 15 transmission assembly. The orbit-changing turntable 15 transmission assembly includes a steering gear 101, a mounting seat 102, and a steering wheel connecting piece 103. The mounting seat 102 is fixed on the outer surface of the annular track panel 11. The steering gear 101 is fixed on the mounting seat 102. The steering wheel connecting piece 103 passes through the annular track panel 11. One end located outside the annular track panel 11 is connected to the steering gear 101, and one end located inside the annular track panel 11 is connected to the orbit-changing turntable 15. When the steering gear 101 rotates, it makes the orbit-changing turntable 15 rotate through the steering wheel connecting piece 103, so as to control the switching between the intersecting ingot seat tracks and the separated ingot seat tracks on the orbit-changing turntable 15.

[0076] In a specific embodiment, the fabric guiding device 3 includes two yarn guide rings. The two yarn guide rings are arranged symmetrically up and down. The two yarn guide rings are respectively connected to the annular track panel 11 through three welding strips, and the three welding strips are arranged at 120°.

[0077] The following combines specific cases to introduce how to use the two-layer four-impeller full-ingot knotless net knitting equipment of the present invention to knit a closed-loop knotless net.

[0078] Using the present invention to weave a 14 - mesh closed - loop knotless net, the knotless net with a net - foot length of 100 mm and a net - foot diameter of 10 mm. There are 56 impellers arranged in 28 circumferential columns and 2 axial rows on the annular - track panel 11, a total of 14 impeller groups, 56 orbit - changing turntables 15. The impeller has 4 notches. The spindle bases are arranged in the notches of the impellers 12 of the impeller groups in the way of 8 occupied and 8 empty, that is, the number of spindle bases is 112. A yarn - carrying device is sleeved on the spindle base. Name the impellers as Ai,j, where the subscripts i and j respectively represent the row and column where the impeller is located; Represent the impeller groups with B k It is expressed that the impellers A1,1, A1,2, A2,1, A2,2 form the impeller group B1, the impellers A1,3, A1,4, A2,3, A2,4 form the impeller group B2, the impellers A1,5, A1,6, A2,5, A2,6 form the impeller group B3... the impellers A1,27, A1,28, A2,27, A2,28 form the impeller group B14.

[0079] The knitting rule of the closed - loop knotless net is as follows:

[0080] (1) The spindle bases 13 and the orbit - changing turntables 15 are in the initial state. The orbit - changing turntables 15 inside each impeller group are in an intersecting state, and the orbit - changing turntables 15 between two adjacent impeller groups are in a separated state, as Figure 9 shown (a, b, c, d, e, f, g and A, B, C, D, E, F, G respectively represent each spindle base 13);

[0081] (2) The orbit - changing turntables 15 inside two adjacent impeller groups where a net - knot is to be knitted rotate 90 degrees, changing from an intersecting state to a separated state;

[0082] (3) All the impellers 12 rotate 90 degrees;

[0083] (4) The orbit - changing turntables 15 between every two adjacent impeller groups rotate 90 degrees, and the orbit - changing turntables 15 change from a separated state to an intersecting state;

[0084] (5) All the impellers 12 rotate 630 degrees to realize the transfer of the spindle bases 13 within two impeller groups. As Figure 10 shown, in the first half - cycle, the spindle bases 13 of B2 and B3 are exchanged, the spindle bases 13 of B4 and B5 are exchanged,..., the spindle bases 13 of B14 and B1 are exchanged; In the second half - cycle, the spindle bases 13 of B1 and B2 are exchanged, the spindle bases 13 of B3 and B4 are exchanged,..., the spindle bases 13 of B13 and B14 are exchanged;

[0085] (6) The orbit - changing turntables 15 inside every two adjacent impeller groups rotate 90 degrees, and the orbit - changing turntables 15 change from a separated state to an intersecting state;

[0086] (7) All the impellers 12 rotate 90 degrees, as Figure 11 shown;

[0087] (8) The orbiting turntable 15 between every two adjacent impeller groups rotates 90 degrees, and the orbiting turntable 15 changes from an intersecting state to a separated state;

[0088] (9) All the impellers 12 rotate 90 degrees, as Figure 12 shown;

[0089] Steps (1) to (9) are continuously repeated, so that the position of the spindle base 13 changes cyclically all the time, and the yarn is woven between the mesh feet and the mesh knots;

[0090] A two-layer four-impeller knotless net knitting device of the present invention can maximize the number of spindle bases, i.e., achieve full spindles, without interference. 8 strands of yarn are woven into mesh feet, and 16 strands of yarn are woven into knots. The knotless net has high strength and good quality.

[0091] The number of notches of the impeller 12 and the arrangement rule of the yarn spindles can be changed according to different knitting requirements of the mesh feet and the mesh knots. When the impeller 12 with m notches weaves the mesh feet, at most 2m spindle bases 13 can be arranged, that is, at most 2m strands of yarn can be woven into the mesh feet, meeting the design requirements of a multi-yarn mesh foot knitting machine, having general applicability, and effectively avoiding the interference problem during the operation of the spindle base 13.

[0092] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
