Description

Technical Field

[0001] The invention relates to the field of circular knitting equipment, in particular to a multifunctional circular knitting machine. Background Art

[0002] Traditional circular knitting machines all have a needle bed, a triangle seat and a knitting triangle set on the triangle seat. The needle bed is equipped with slidable knitting needles, and the knitting triangle controls the movement of the knitting needles to weave knitted fabrics with various structures such as jacquard, tuck, and transfer.

[0003] During use, according to the different styles of knitted fabrics, such as cotton flannel, terry cloth, ribbed cloth, mesh cloth and other fabrics, it is necessary to select the corresponding circular knitting machine for knitting. For smaller weaving factories, the knitting machines they purchased have a single function, which limits the styles of knitted fabrics in the orders they receive. If they want to expand their production range, they need to purchase different types of circular knitting machines, which greatly increases production costs. In addition, when knitting, the circular knitting machine needs to adjust the needle press triangle according to the changes in the knitting structure. For example, when knitting seamless underwear, since the body and hem of the seamless underwear have different knitting structures, the needle press triangle must be moved for adjustment. At the same time, the thickness, color and pattern combination of the fabric require adjustment of the equipment operating speed and yarn introduction. Traditional circular knitting machines rely on the operator's experience, have low adjustment accuracy, and cannot achieve dynamic adjustment during the knitting process. The adjustment efficiency is low, affecting production continuity. Summary of the Invention

The first connecting member 14 and the second connecting member 15 are connected by the bearing 16, and the middle member 18 is arranged on the second connecting member 15 for installing the upper triangular seat 25, thereby making the component layout compact, reducing the occupied space, improving space utilization, and improving the convenience of maintenance. At the same time, more auxiliary accessories can be installed, which facilitates the intelligent improvement of the equipment.

[0022] In this embodiment, the upper end cover of the frame 1 is provided with a large tripod cover 39. The closed design prevents dust from entering the gear meshing area, ensures the lubrication effect, reduces operating noise, and improves operational safety.

[0023] Further, the upper end of the first connecting member 14 is connected to the large tripod gear 9 through a first bolt 41, and the lower end of the first connecting member 14 is connected to the needle disc base 17 through a second bolt 42. A relief groove 43 for the first connecting member 14 to be embedded is recessed in the middle of the needle disc base 17.

Moreover, a first through hole 44 is provided in the middle of the large tripod gear 9, and a mounting member 45 with an inverted "U" - shaped structure is provided at the first through hole 44. The opening of the mounting member 45 faces downward, and a second through hole 46 for the first connecting member 14 to be embedded is provided in the middle of the mounting member 45.

In this embodiment, the first connecting member 14 and the second connecting member 15 are tubular structures.

[0024] Moreover, an external thread 47 is provided on the upper part of the outer surface of the second connecting member 15.

[0025] In this embodiment, the upper triangle 26 or the lower triangle 24 includes a first pressing triangle 101 and a second pressing triangle 102, and the upper triangle seat 25 or the lower triangle seat 23 includes a base 103, a slider 104, a knob 105 and a pin 106. The front of the base 103 is provided with a slide groove 107, and the back of the base 103 is provided with a through hole 108 connected to the slide groove 107. The upper line adjustment motor 35 or the lower line adjustment motor 34 is provided on the back of the base 103, and the knob 105 is provided on the lower line adjustment motor 3 4 or on the rotating shaft of the upper thread adjustment motor 35, and distributed at the through hole 108, the front of the knob 105 is provided with a spiral track 109, the slider 104 is slidable up and down in the slide groove 107, the back of the slider 104 is provided with a pin hole 110, the axial ends of the pin shaft 106 are respectively embedded in the pin hole 110 and the spiral track 109, the first press needle triangle 101 is locked on the slider 104, the second press needle triangle 102 is locked on the base 103, and is distributed on the first press needle triangle 10 1, the circular knitting machine drives the drive motor to operate according to the instructions of its controller 401. When in use, the upper thread adjustment motor 35 or the lower thread adjustment motor 34 drives the knob 105 to rotate, so that the pin 106 embedded in the spiral track 109 on the knob 105 drives the slider 104 to slide up and down along the slide groove 107, thereby adjusting the distance between the first presser cam 101 and the second presser cam 102 on the slider 104, thereby changing the size of the knitted loop and thus changing the density of the fabric. This structure can be adjusted during the knitting process of the circular knitting machine, avoiding shutdown adjustments, ensuring good production continuity, and thus improving production efficiency. In addition, by controlling the upper thread adjustment motor 35 or the lower thread adjustment motor 34 to drive the knob 105 to rotate, the rotary motion is converted into a precise linear displacement of the slider 104, realizing stepless linear adjustment of the knitting density, which can improve the accuracy and efficiency of the adjustment. At the same time, the integrated layout of the motor on the back of the base 103 and the front actuator ensures adjustment accuracy while optimizing equipment space utilization.

[0026] In addition, an axial hole 111 is provided through the center axis of the knob 105, and a threaded hole 112 is provided on the circumferential surface of the knob 105 and along its radial direction to communicate with the axial hole 111. An annular groove 113 is recessed on the axial middle part of the circumferential surface of the knob 105. The combined design of the axial hole 111 and the threaded hole 112 enables rapid disassembly and assembly of the knob 105 and the rotating shaft of the upper line adjustment motor 35 or the lower line adjustment motor 34. The annular groove 113 structure facilitates the installation of anti-loosening retaining springs, which significantly improves assembly efficiency. The radial threaded hole 112 cooperates with the set screw to form a double fixation, which effectively avoids the axial movement problem caused by traditional key connection and improves transmission stability.

[0027] In this embodiment, the width of the spiral track 109 is smaller than the diameter of the pin hole 110, forming a dynamic compensation gap of 0.05-0.1mm, eliminating the motion jamming phenomenon caused by processing errors, allowing the pin shaft 106 to deflect slightly in the track, reducing the stress concentration on the contact surface, and improving the durability of the mechanism by 2.5 times.

[0028] Specifically, the pin shaft 106 includes an intermediate shaft 121, a first pipe sleeve 122 and a second pipe sleeve 123. The first pipe sleeve 122 and the second pipe sleeve 123 are respectively rotatably sleeved on the axial ends of the intermediate shaft 121 through bearings. The first pipe sleeve 122 is embedded in the spiral track 109, and the second pipe sleeve 123 is embedded in the pin hole 110. The double-sleeve bearing structure reduces the friction coefficient to below 0.02, which saves 18% energy compared to the traditional integral pin shaft. The floating connection design between the intermediate shaft 121 and the pipe sleeve can automatically compensate for the axis deviation within 0.5° to ensure the straightness of the movement of the slider 104.

[0029] Furthermore, a protrusion 124 with an arc-shaped structure is convexly provided on the circumferential surface of the second pipe sleeve 123. The arc structure of the protrusion 124 forms a line contact with the pin hole 110, which can reduce friction damage and improve adjustment efficiency. In addition, the protrusion 124 produces a self-centering effect, so that the axial positioning accuracy of the second pipe sleeve 123 is high, which can eliminate the dead point problem of the single eccentric wheel.

[0030] In this embodiment, the fabric winding assembly 37 includes a winding frame 371, a support shaft 372, a bearing seat 373, a winding roller 374, a winding motor 375, a clamping roller 376 and two adjustment assemblies 377. The winding frame 371 is rotatably provided on the frame 1 through the support shaft 372 and the bearing seat 373. The winding roller 374 is rotatably provided with the lower part of the winding frame 371. The winding motor 375 is connected to the winding roller 374. The clamping roller 376 is rotatably provided on the winding frame 371 and is located on the upper side of the winding roller 374. The winding frame 371 is connected to the frame 1 through the two adjustment assemblies 377. The large disc gear 8 is connected, and the two adjustment components 377 are axially symmetrically distributed. The adjustment component 377 realizes the pitch adjustment of the winding frame of ±5° and the axial fine-tuning of ±3mm through the three-dimensional hinge mechanism, which can compensate for the 0.1-0.5mm differential change of the fabric thickness in real time. It is particularly suitable for constant tension winding of elastic fabrics, so that the winding tension is balanced, thereby improving the stability of the equipment operation. The integrated design of the middle dust removal component 38 and the fabric winding component 37 enables the dust removal operation position to be moved forward to the weaving forming section. In conjunction with the negative pressure adsorption system, it can remove more than 90% of the free fibers, reducing the risk of secondary contamination of the fabric compared to the end dust removal.

[0031] Specifically, the adjustment component 377 includes a first connecting rod 201, a second connecting rod 202 and a telescopic rod 203. The upper end of the first connecting rod 201 is vertically arranged on the large plate gear 8, one end of the telescopic rod 203 is hinged to the lower end of the first connecting rod 201, one end of the second connecting rod 202 is hinged to the other end of the telescopic rod 203, and the other end of the second connecting rod 202 is hinged to the upper end of the winding frame 371. The three-link hinge mechanism, namely the first connecting rod 201, the telescopic rod 203, and the second connecting rod 202 form a spatial four-degree-of-freedom adjustment system. The electric push rod of the telescopic rod 203 can achieve displacement control with an accuracy of 0.01mm. In conjunction with the angle sensor, it can automatically compensate for the 0.2-0.7mm amplitude offset caused by centrifugal force. The universal joint hinge design makes the adjustment component 377 have anti-torsion characteristics, and can still maintain adjustment stability at a speed of 1500rpm, and the vibration amplitude is reduced compared with the traditional rigid connection method.

[0032] In addition, the second connecting rod 202 is distributed along the axial direction of the winding roller 374, and the second connecting rod 202 is arranged axially parallel to the winding roller 374 to form a couple balance structure, so that the adjustment torque is evenly distributed along the roller surface, avoiding deformation of the roller body caused by single-point stress concentration. This layout ensures that the line of action of the adjustment force always passes through the center of mass of the winding frame 371, reducing the generation of additional inertia moment and reducing the vibration value of the equipment during the acceleration stage.

[0033] In this embodiment, the middle section dust removal assembly 38 includes a first support rod 381, a connecting seat 382, ​​a second support rod 383 and two dust removal rollers 384. The connecting seat 382 is rotatably provided at the lower end of the first support rod 381 through a bearing, and the second support rod 383 is provided on the connecting seat 382. The second support rod 383 is distributed along the transverse direction. The two dust removal rollers 384 are rotatably provided at the lateral ends of the second support rod 383. The rotating mechanism of the second support rod 383 realizes adaptive adjustment of the angle of 15-35°, and the dust removal contact area is increased. The design of the rotatable connecting seat 382 enables the dust removal roller 384 to automatically deflect ±8° following the direction of the fabric to avoid scratches on the fabric surface caused by hard contact.

[0034] Furthermore, the second support rod 383 includes a cross bar 301 and an oblique rod 302 arranged on both sides of the cross bar 301. The two dust removal rollers 384 are respectively arranged on the free ends of the oblique rod 302. The angle between the central axis of the oblique rod 302 and the central axis of the cross bar 301 is 120°. The truss structure of the oblique rod 302 and the cross bar 301 improves the overall rigidity, and the deformation is small when subjected to lateral force. The angle design enables the dust removal roller 384 to form tangential contact with the fabric, reducing the positive pressure while maintaining an effective insertion depth of 8mm for the dust removal bristles.

[0035] Although the present invention has been particularly shown and described in conjunction with preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made to the present invention without departing from the spirit and scope of the invention as defined in the appended claims, and all such changes are within the scope of protection of the present invention.
