Description

Technical Field

[0001] The present application relates to a circular loom, in particular to a circular loom cam, a heald adjusting mechanism and a twill six-shuttle circular loom. Background Art

[0002] As an important textile equipment, circular looms play an important role in industrial production and daily life. As the market's requirements for weaving quality and production efficiency continue to increase, various types of circular looms continue to emerge, especially for the growing demand for complex pattern weaving, which makes the design of circular looms pay more and more attention to precise control and efficient operation.

[0003] At present, circular looms mainly use cams to drive the heald frame assembly to achieve the lifting and lowering movement of the healds, and to achieve staggered weaving between the healds and the horizontal wires. However, the slide rails on the existing cams are sine or cosine tracks. During the cam driving process, the heald weaving code is single, 10101010 or 110011001100 along the length direction (1 is the state code above the horizontal wire, and 0 is the state code below the horizontal wire). In order to obtain the heald weaving state of 110-011-101-110-011-101 along the length direction, it is necessary to add a cantilever or other mechanism with a wire adjustment function, which makes the circular loom structure more complicated and easily becomes a new fault point under high-speed weaving, affecting and restricting production efficiency. Summary of the invention

[0004] In order to efficiently produce a woven fabric in a heald weaving state of 110-011-101-110-011-101, a circular loom cam, a heald adjusting mechanism and a twill six-shuttle circular loom are provided.

[0005] The above first invention objective of the present invention is achieved through the following technical solutions: A circular loom cam comprises an outer wheel connected to a driving mechanism and an inner wheel roller located outside, the outer wheel is coaxial with the inner wheel, and three guide slideways arranged in the circumferential direction and used to drive a heald frame assembly are arranged on the outer peripheral side of the outer wheel, and the guide slideways are obtained by arranging and combining different slideway sections; the slideway sections are: Corresponding to the positive rising section of the sine curve 0~π / 2 trajectory, The peak segment of the wave peak is maintained flat, Corresponding to the positive falling section of the sine curve π / 2~π trajectory, Corresponding to the negative falling section of the sine curve π~3π / 2 trajectory, The valley segment that maintains the valley value flatly, Corresponding to the negative rising section of the sine curve 3π / 2~2π trajectory, The staggered wire section first descends and then rises, with the lowest point located in the middle and the lowest point higher than the initial point of the positive rising section; The guide slideway is divided into a first slideway, a second slideway and a third slideway in the radial direction, and the 0° positions of the first slideway, the second slideway and the third slideway in the circumferential direction are aligned; The first slide 0-180° is a positive rising section, a peak section, a positive falling section, a positive rising section, a peak section, a positive falling section, a negative falling section, a valley section, and a negative rising section connected in sequence along the circumferential direction. The first slide 0-180° is repeated with the first slide 180-360°; The second slideway 0-180° is a negative drop section, a valley section, a negative rise section, a positive rise section, a peak section, a positive drop section, a positive rise section, a peak section, and a positive drop section connected in sequence along the circumferential direction. The second slideway 0-180° repeats the first slideway 180-360°; The third slide 0-180° is a positive rising section, a peak section, a positive falling section, a negative falling section, a valley section, a negative rising section, a positive rising section, a peak section, and a positive falling section connected in sequence along the circumferential direction. The third slide 0-180° repeats the first slide 180-360°; The connection parts of the positive rising section and the positive falling section in the first slide, the second slide and the third slide are replaced with staggered thread sections for transition. After the replacement, the circumferential angles occupied by the positive rising section, the staggered thread section and the positive falling section are equal to the sum of the circumferential angles occupied by the replaced positive rising section and the positive falling section alone.

[0006] By adopting the above technical solution, the cam is used in conjunction with the heald frame assembly, each guide slide is equipped with a heald frame assembly, a group of healds are hung on the top of each heald frame assembly, and the heald frame assembly is driven by the guide slide to drive the healds to rise and fall. Here, the heald driven to rise and fall by the first slide is recorded as the first wire, the heald driven to rise and fall by the second slide is recorded as the second wire, and the heald driven to rise and fall by the third slide is recorded as the third wire. The cam is driven to rotate, so that the first wire, the second wire, and the third wire pass through six staggered wire sections during one rotation of the cam, and are staggered with the horizontal wire six times, with 1 as the state code above the horizontal wire and 0 as the state code below the horizontal wire, to obtain a texture weaving with alternating weaving state codes of 110-011-101-110-011-101 along the length direction of the heald and high weaving efficiency.

[0007] Optionally: the staggered wire segment is a symmetrical smooth curve.

DETAILED DESCRIPTION

[0022] The following embodiments are further described in conjunction with the accompanying drawings.

[0023] Example 1 As attached Figure 1 As shown, a circular loom cam includes an inner wheel 311 and an outer wheel 312. The outer wheel 312 is coaxially arranged outside the inner wheel 311. The outer wheel 312 and the inner wheel 311 are connected and fixed via the wheel hub 313. The number of the wheel hubs 313 is determined according to the size of the outer wheel 312. The larger the outer diameter and the heavier the outer wheel 312, the more the number of the wheel hubs 313. Here, the number of the wheel hubs 313 is six.

[0024] Three guide slideways 314 are arranged circumferentially on the outer peripheral side of the outer wheel 312. The three guide slideways 314 are named as the first slideway 314a, the second slideway 314b and the third slideway 314c in sequence along the axial direction of the outer wheel 312, and the 0° positions of the first slideway 314a, the second slideway 314b and the third slideway 314c are aligned in the circumferential direction.

[0025] The guide slide 314 has a rise and fall along the circumferential direction, and a flat section that maintains a crest or a trough. Due to the undulating setting of the guide slide 314, it is convenient to express its undulating changes. Here, the direction from the first slide 314a to the third slide 314c along the axial direction of the outer wheel 312 is defined as from top to bottom, that is, the outer wheel 312 is axially vertical, the first slide 314a is located above the third slide 314c, and the guide slide 314 has a crest at the top and a trough at the bottom.

[0026] As attached Figure 1 and attached Figure 2 As shown, based on the wave crests and wave troughs, the guide slide 314 has a reference loop 3141 (blue), the reference loop 3141 is coaxial with the outer wheel 312, and the height difference from the reference ring to the wave crests and wave troughs is equal.

[0027] As attached Figure 2 As shown, according to the reference loop 3141, wave crests, wave troughs, and rising and falling trends, the guide slide 314 has multiple standard slide sections, and the first slide 314a, the second slide 314b, and the third slide 314c are formed by the arrangement and combination of different slide sections.

[0028] The slideway section includes a positive rising section 3142 , a peak section 3143 , a positive falling section 3144 , a negative falling section 3145 , a valley section 3146 , and a negative rising section 3147 .

[0029] The positive rising section 3142, the positive falling section 3144, the negative falling section 3145, and the negative rising section 3147 are all sinusoidal curve trajectories.

[0030] The positive rising section 3142 rises from the reference loop line 3141 to the wave crest, corresponding to the trajectory of the sine curve 0 to π / 2.

[0031] The positive falling section 3144 descends from the wave crest to the reference loop line 3141, corresponding to the trajectory of the sine curve π / 2~π.

[0032] The negative descending section 3145 starts from the reference loop line 3141 and descends to the trough, corresponding to the trajectory of the sine curve π to 3π / 2.

[0033] The negative rising section 3147 rises from the trough to the reference loop line 3141, corresponding to the trajectory of the sine curve π / 2~π.

[0034] The peak segment 3143 is a flat maintaining wave peak.

[0035] The valley value segment 3146 is a flat valley value.

[0036] The sliding section in the first slideway 314a is as follows: 0~24° is the positive rising section 3142, 24~36° is the peak section 3143, 36~60° is the positive falling section 3144, 60~84° is the positive rising section 3142, 84~96° is the peak section 3143, 96~120° is the positive falling section 3144, 120~144° is the negative falling section 3145, 144~156° is the valley section 3146, 156~180° is the negative rising section 3147; 180°~360° repeats 0~180°.

[0037] The sliding section in the second slideway 314b is as follows: 0~24° is a negative falling section 3145, 24~36° is a valley section 3146, 36~60° is a negative rising section 3147, 60~84° is a positive rising section 3142, 84~96° is a peak section 3143, 96~120° is a positive falling section 3144, 120~144° is a positive rising section 3142, 144~156° is a peak section 3143, and 156~180° is a positive falling section 3144; 180°~360° repeats 0~180°.

[0038] The sliding section in the third slideway 314c is as follows: 0~24° is the positive rising section 3142, 24~36° is the peak section 3143, 36~60° is the positive falling section 3144, 60~84° is the negative falling section 3145, 84~96° is the valley section 3146, 96~120° is the negative rising section 3147, 120~144° is the positive rising section 3142, 144~156° is the peak section 3143, 156~180° is the positive falling section 3144, and 180°~360° repeats 0~180°.

[0039] As attached Figure 1 and attached Figure 2 As shown, the slideway section also includes a specific staggered wire section 3148, which is a key section for the heald wire interlacing and folding sequence, and is a symmetrical, first descending and then ascending concave curve, with its lowest point higher than the reference loop line 3141. The curve trajectory of the staggered wire section 3148 is preferably a parabola, which can smoothly transition and reduce the stagnation and wear of the cam 31 during the driving operation.

[0040] When the positive rising section 3142 and the positive falling section 3144 are combined in the first slide 314a, the second slide 314b and the third slide 314c, the transition area is replaced by the staggered thread section 3148. The circumferential angle occupied by the staggered thread section 3148 is 100 degrees less than that of the positive rising section 3142 and the positive falling section 3144 on both sides, that is, After replacement, the circumferential angles occupied by the positive rise section 3142, the staggered wire section 3148, and the positive drop section 3144 are equal to the sum of the circumferential angles occupied by the replaced positive rise section 3142 and the positive drop section 3144. The circumferential angle occupied by the staggered wire section 3148 can be adjusted according to the size of the outer wheel 312. Here, the staggered wire section 3148 occupies 8°. The trajectory of the positive rise section 3142 connected to the staggered wire section 3148 is changed to a sinusoidal trajectory corresponding to 0.083π~π / 2, and the trajectory of the positive drop section 3144 connected to the staggered wire section 3148 is changed to a sinusoidal trajectory corresponding to π / 2~9.834π.

[0041] In the first slide 314a, 56-64° and 236-244° are staggered thread sections 3148, in the second slide 314b, 116-124° and 296-304° are staggered thread sections 3148, and in the third slide 314c, 356-4° and 176-184° are staggered thread sections 3148.

[0042] The slide sections of the first slide 314a, the second slide 314b, and the third slide 314c can also be referred to in Table 1 below for reference.

[0043] Note: A staggered thread section 3148 is provided between the “positive descending section 3144*” and the “positive ascending section 3142*”.

[0044] In other embodiments, the circumferential angles occupied by the peak segment 3143 and the valley segment 3146 can be increased or decreased, and the circumferential angles occupied by other slide segments can be increased proportionally to make up 360°. The speeds of the lift and descent can be adjusted in turn to adapt to wire materials of different toughnesses, avoiding the problem of frequent wire breakage caused by excessive lift and descent.

[0045] Combined with Figures 2 to 4 It can be seen that the circular loom cam of this embodiment is used in conjunction with a heald frame assembly, each guide slide 314 is equipped with a heald frame assembly, a group of healds are hung on the top of each heald frame assembly, and the heald frame assembly is driven by the guide slide 314 to drive the healds to rise and fall. Here, the healds driven to rise and fall by the first slide 314a are marked as the first wire (dark blue mark), the healds driven to rise and fall by the second slide 314b are marked as the second wire (red mark), and the healds driven to rise and fall by the third slide 314c are marked as the third wire (magenta mark).

[0046] The height of the first wire is recorded as H1, and the height of the first wire is h1 when the first slide 314a is in the peak section 3143; the height of the second wire is recorded as H2, and the height of the second wire is h2 when the second slide 314b is in the peak section 3143; the height of the third wire is recorded as H3, and the height of the third wire is h3 when the third slide 314c is in the peak section 3143; h1=h2=h3.

[0047] Starting from the outer wheel 3120° position, the first wire, the second wire, the third wire and the horizontal wire are interlaced as follows: at 0°, the first wire and the second wire are at the same height, and the third slide 314c is located at the lowest point of the staggered wire section 3148, so the third wire is located above the first wire and the second wire.

[0048] From 0° to 24°, the first and third wires gradually rise until they are at the same height, while the second wire descends.

[0049] At 24° to 36°, keep the first and third threads on top and the second thread on the bottom.

[0050] At 36° to 56°, the first and third threads begin to descend, and the second thread begins to ascend.

[0051] At 56° to 64°, in this interval, the first slide 314a enters the staggered wire section 3148, the first wire first drops and then rises, the second wire enters the positive rise section 3142 from the negative rise section 3147 and keeps rising, and the third wire enters the negative fall rise section from the positive fall rise section and keeps falling. Since the lowest point of the staggered wire section 3148 is higher than the reference loop 3141, at 60°, the first wire drops to the lowest point of the interval and is higher than the third wire, so that a gap is staggered between the first wire and the third wire, and at this time, the second wire is at the same height as the third wire, the second wire goes up, and the third wire goes down, and at this time the horizontal wire enters below the first wire. After 60°, the first wire and the second wire continue to go up, and the third wire goes down, and the horizontal wire continues to pass through the gap below the second wire and above the third wire, realizing weaving with this staggered wire. With 1 as the state code above the horizontal wire, and 0 as the state code below the horizontal wire, the first wire, the second wire, and the third wire are represented in order, and the braiding state code obtained by the heald after 56° to 64° is 110; Similarly, through the staggered wire section 3148 of the second slide 314b at 116-124°, the first wire and the second wire go down, and the third wire goes up. At 120°, the second wire is on the top and the first wire is on the bottom. After 120°, the second wire and the third wire continue to go up and down, and the first wire goes down, realizing the second staggered wire weaving. The braiding state code obtained by the heald is 011. The third staggered weaving is realized through the staggered wire section 3148 of the third slideway 314c at 176-184 degrees, and the weaving state code of the heald is 101; The fourth staggered weaving is achieved through 236-244°, and the weaving status code of the heald is 110; The fifth staggered weaving is achieved through 296-304°, and the weaving status code of the heald is 011; The sixth staggered weaving is achieved through 356-4°, and the weaving status code of the heald is 101; Thus, the cam 31 rotates one circle to realize six times of staggered weaving of three groups of heald frame assemblies, with high weaving efficiency and the woven healds having an alternating texture of 110-011-101-110-011-101 along the length direction.

[0052] Example 2 As attached Figure 5 As shown, a heald adjusting mechanism comprises the cam 31 of embodiment 1, a heald frame assembly 32 and a lifting assembly 33.

[0053] There are multiple lifting components 33 , which are arranged around the cam 31 in a circle with the axis of the cam 31 as the axis.

[0054] As attached Figure 6 and attached Figure 7 As shown, the lifting assembly 33 includes two vertical guide rods 331. Three drive seats 332 are slidably connected to the two guide rods 331, and the drive seats 332 are sequentially recorded as a first drive seat 332a, a second drive seat 332b and a third drive seat 332c from top to bottom.

[0055] A first driving block 3321 is disposed on the side of the first driving seat 332a facing the outer wheel 312 , a second driving block 3322 is disposed on the side of the second driving seat 332b facing the outer wheel 312 , and a third driving block 3323 is disposed on the side of the third driving seat 332c facing the outer wheel 312 .

[0056] The first driving block 3321, the second driving block 3322 and the third driving block 3323 are all cylinders with horizontal axes and perpendicular to the axis direction of the outer wheel 312. The diameters of the first driving block 3321, the second driving block 3322 and the third driving block 3323 are equal to the width of the guide slide 314. The first driving block 3321 is inserted into the first slide 314a, the second driving block 3322 is inserted into the second slide 314b, and the third driving block 3323 is inserted into the third slide 314c. Therefore, when the cam 31 rotates, the first driving block 3321, the second driving block 3322 and the third driving block 3323 are pushed by the guide slide 314 to rise and fall accordingly.

[0057] In addition, the first driving seat 332a is vertically penetrated by a first through hole 3324, a second through hole 3325 and a first fixing hole 3326. The first through hole 3324, the second through hole 3325, the first fixing hole 3326 and the axis of the outer wheel 312 are located in the same vertical plane.

[0058] The second driving seat 332 b is located directly below the first driving seat 332 a , and is provided with a third through hole 3327 coaxial with the first through hole 3324 and a second fixing hole 3328 coaxial with the second through hole 3325 .

[0059] The third driving seat 332c is located directly below the second driving seat 332b and defines a third fixing hole 3329 coaxial with the first through hole 3324 .

[0060] The heald frame assembly 32 includes a vertical heald rod 321 and a heald plate 322 installed at the upper end of the heald rod 321. The number of heald frame assemblies 32 is three times that of the lifting assembly 33.

[0069] The cam 31 of the heald adjusting mechanism 3 is coaxially sleeved on the rotating shaft 1 and rotates along with the rotating shaft 1 .

[0070] The lifting assembly 33 and the heald frame assembly 32 are installed on the frame 21. The lifting assembly 33 is located inside the frame 21. The heald frame assembly 32 is located above the frame 21, and the lower end of the heald rod 321 is inserted into the frame 21 and connected to the lifting assembly 33.

[0071] The horizontal thread adjustment mechanism 4 comprises a flywheel 41 coaxially fixed to the upper end of the rotating shaft 1 and a shuttle 42 mounted on the flywheel 41. The number of the shuttles 42 is six, which are arranged in a circular array around the rotating shaft 1 and are used to install the horizontal threads.

[0072] When the circular loom of the present application is started, the rotating shaft 1 rotates, driving the shuttle 42 to rotate and the heald frame assembly 32 to rise and fall alternately, thereby achieving alternating twill weaving of the healds along the length direction of 110-011-101-110-011-101, obtaining a woven tube belt with high structural strength and good weaving precision, and high production efficiency.
