Description

Technical Field

[0001] The invention relates to the field of circular knitting machines, and in particular to an adjustable triangle seat. Background Art

[0002] The circular knitting machine is composed of a frame, a yarn supply mechanism, a weaving mechanism, a transmission mechanism, a lubrication and dust removal mechanism, an electrical control mechanism, a pulling and winding mechanism and other auxiliary devices. The weaving mechanism is the core of the circular knitting machine, which mainly includes a needle cylinder, a needle disc, a knitting needle, a triangle seat, a triangle fixed on the triangle seat and other components. The traditional triangle seat is provided with one or more threaded holes, which are threadedly connected to the threaded holes by bolts, thereby fixing the triangle on the triangle seat. However, when the circular knitting machine is weaving different styles of fabrics, the triangle needs to be replaced to adapt to the process steps of weaving the fabrics, and the position of the threaded hole on the triangle seat is fixed, which is difficult to adapt to the installation of the triangle. It is necessary to specially make a triangle that matches its installation, or to connect the triangle seat and replace it together, which makes the use cost expensive.

[0003] The existing triangular seat is provided with a slider and a threaded hole is provided on the slider to adjust the position of the threaded hole. For example, Chinese patent application No. 201310078290.7 discloses a lower triangular adjustment mechanism for a small circular knitting machine. The lower triangular seat is saddle-shaped and is formed with countersunk holes, large holes, small holes, screw holes and T-shaped slots. A slider tapered hole is formed on one side of the T-shaped slider, and a slider countersunk hole is formed on the other side. The adjustment column is formed with a stepped hole and a through hole; the third compression spring is placed in the key-shaped slot of the lower triangular seat, and the T-shaped slider is inserted into the T-shaped slot of the lower triangular seat. The first adjusting screw passes through the first compression spring, the through hole of the adjusting column, and the screw hole on the lower triangular seat, and its conical head is inserted into the third compression spring on the lower triangular seat. The second compression spring is placed in the small hole on the lower triangular seat, and the steel ball is placed on the second compression spring. The adjusting column is placed in the large hole on the lower triangular seat and pressed against the steel ball. The first compression spring is placed in the stepped hole of the adjusting column. The first adjusting screw passes through the first compression spring, the through hole of the adjusting column, and the screw hole on the lower triangular seat, and its conical head is pressed against the conical hole of the slider on the T-shaped slider.

[0004] During installation, the T-shaped slider is embedded into the T-shaped slot from the upper or lower end of the T-shaped slot of the triangular seat, and then threadedly connected to the threaded hole through the first adjusting screw. The inner end of the first adjusting screw abuts against the side of the slider tapered hole of the slider, and is threadedly connected to the slider through the second adjusting screw. The inner end of the second adjusting screw is embedded in the key slot and abutted by the third compression spring, thereby fixing the T-shaped slider.

[0005] However, the following defects were found in actual use:

[0006] 1) The sliding direction of the T-shaped slider in the T-shaped groove is limited by the cooperation of the second adjusting screw and the third compression spring. When the needle cylinder rotates, the knitting needle on the needle cylinder is driven to rotate along the central axis of the needle cylinder. The needle butt on the knitting needle is embedded in the track of the triangle. The knitting needle can move in the needle groove of the needle cylinder along the axial direction of the needle cylinder through the triangle track. In the process of pushing the knitting needle to move, the knitting needle also acts on the triangle with a reaction force, thereby causing the force to act on the slider, and the first adjusting screw abuts against one side of the slider cone hole of the slider, and the third compression spring is elastic, which is easy to cause the reciprocating vibration of the T-shaped slider under the force, resulting in poor quality of the woven fabric;

[0007] 2) The running vibration of the circular knitting machine is transmitted to the T-shaped slider, which can also easily cause the reciprocating vibration of the T-shaped slider, resulting in poor quality of the woven fabric. Summary of the invention

[0008] Therefore, in view of the above problems, the present invention provides an adjustable triangle seat, which mainly solves the problem of poor stability of the slider on the adjustable triangle seat in the prior art, resulting in poor weaving quality.

[0009] To achieve the above object, the present invention adopts the following technical solutions:

The back of the slider is provided with a second groove for the inner end of the second adjusting screw to be embedded, and the second groove has an inclined surface. The front side of the base and the two lateral sides of each step portion are provided with a third threaded hole. A block is provided on the truss at each step portion, and is connected to the third threaded hole by a locking bolt. The vertical length dimension of the step portion is greater than the vertical width dimension of the block. When the slider is installed, the inner end of the second adjusting screw rests on the inclined surface; the first spring rests on the inner end of the first adjusting screw; the front side of the step portion rests on the back side of the block.

[0011] Furthermore, there are two slide grooves, and the two slide grooves are distributed side by side.

[0012] Furthermore, the surface of the step portion is provided with an anti-slip pad.

[0013] Furthermore, a disk body is fixed to the outer end of the second adjusting screw, and a plurality of positioning holes are evenly arranged around the bottom surface of the disk body. Two second mounting holes are arranged on the back side of the base and around the second threaded hole, and a second spring and a positioning rod are arranged in each of the second mounting holes.

After the adjustment is completed, when the second adjusting screw abuts against the inclined surface, it generates an upward cutting force and an outward force, and the outward force pushes the slider to abut against the block, so that the slider and the block form a static friction force, and a balance is formed by the elastic force of the second spring, the upward cutting force, the force acting on the slider during the track movement of the needle butt of the knitting needle along the triangle, and the static friction force, or, a balance is formed by the elastic force of the second spring, the upward cutting force, the force transmitted to the slider by the vibration of the equipment, and the static friction force, thereby limiting the movement of the slider, that is, the slider forms a fixed state, so that the quality of the woven fabric is guaranteed; when installing , by embedding the slider in the slide groove, and then locking the block at the third threaded hole by a bolt, and threading the second adjusting thread with the second threaded hole, so as to adjust the position of the slider, the cam is threadedly connected to any first mounting hole on the slider by a bolt, so that the cam is fixedly connected, and through the provision of multiple first mounting holes, the cam installation of different specifications can be matched, so that when replacing the cam and the slider, it is directly replaced without disassembling the needle cylinder and the needle disk. Compared with a lower cam adjustment mechanism of a small circular knitting machine disclosed in Chinese patent application No.: 201310078290.7, due to the T-slot provided, the T-shaped slider needs to be pulled out from its upper end or lower end during the replacement of the slider, so that the replacement of the T-shaped slider requires the equipment to remove the needle disk and other components. The adjustable cam seat is easy to use, and at the same time, the fine adjustment of the cam is achieved by rotating the second adjusting screw, so that the cam installation has high accuracy, thereby improving the weaving quality.

[0027] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0028] The embodiments of the present invention are:

[0029] refer to Figures 1 to 7 As shown, an adjustable triangle seat comprises a base 1, wherein the side of the base 1 close to the triangle is defined as the front side, and the side away from the triangle is defined as the back side. A slide groove 2 is provided on the front side of the base 1, and the slide groove 2 is distributed in the vertical direction. Two sliders 3 are arranged in the slide groove 2, and two step portions 4 are recessed in the front side of each slider 3. A first threaded hole 5 and at least one first mounting hole 6 are provided on the slider 3. Preferably, the number of the first mounting holes 6 is two, and the first threaded hole 5 is threadedly connected with a first adjusting screw 7. The bottom surface of the slide groove 2 is provided with a first groove 8 for the inner end of the first adjusting screw 7 to be embedded. The first groove 8 comprises a first portion 81 and a second portion 82 which are interconnected. The width dimension of the first portion 81 is smaller than the width dimension of the second portion 82. A first spring 9 is embedded in the second portion 82. After the first adjusting screw 7 is embedded in the first portion 81, the first spring 9 is embedded through the second portion 82, so that the first adjusting screw 7 The installation stability of an adjusting screw 7 and a first spring 9 is good, and the directional sliding of the slider 3 can be limited to improve the stability. A second threaded hole 10 is provided on the bottom surface of the slide groove 2 and on the circumferential side of the first groove 8. The second threaded hole 10 is threadedly connected with a second adjusting screw 11. A second groove 12 is provided on the back of the slider 3 for the inner end of the second adjusting screw 11 to be embedded. The second groove 12 has an inclined surface 121. A third threaded hole 13 is provided on the front side of the base 1 and on both sides of each step 4 in the lateral direction. A block 14 is provided on the truss at each step 4 and is connected to the third threaded hole 13 by a locking bolt. The length dimension of the step 4 in the vertical direction is greater than the width dimension of the block 14 in the vertical direction. When the slider 2 is installed, the inner end of the second adjusting screw 11 abuts on the inclined surface 121; the first spring 9 abuts on the inner end of the first adjusting screw 7; the front side of the step 4 abuts on the back side of the block 14.

[0030] The adjustable triangle seat, when adjusting, the inner end of the second adjusting screw 11 abuts against the inclined surface 121 of the slider 3, and the second adjusting screw 11 is rotated inwardly, thereby pushing the slider 3 to move upward. At the same time, the first adjusting screw 7 threadedly connected to the slider 3 squeezes the first spring 9. After the adjustment is completed, when the second adjusting screw 11 abuts against the inclined surface 121, it generates an upward cutting force and an outward force, and the outward force pushes the slider 3 against the block 14, so that the slider 3 and the block 14 form a static friction force, and the elastic force of the first spring 9, the upward cutting force, the force acting on the slider during the track movement of the needle butt along the triangle, and the static friction force form a balance, or the elastic force of the first spring 9, the upward cutting force, the force transmitted to the slider by the vibration of the equipment, and the static friction force form a balance, thereby limiting the movement of the slider 3, that is, the slider 3 is fixed, so that the quality of the woven fabric is guaranteed; during installation, The slider 3 is embedded in the slide groove 2, and then the block 14 is locked at the third threaded hole 13 by a bolt, and the second adjusting screw 11 is threadedly connected with the second threaded hole 10, so as to adjust the position of the slider 3. The cam is threadedly connected with any first mounting hole 6 on the slider by a bolt, so that the cam is fixedly connected, and through the multiple first mounting holes, the cam installation of different specifications can be matched, so that when the cam and the slider are replaced, they can be directly replaced without disassembling the needle cylinder and the needle disk. Compared with the lower cam adjustment mechanism of a small circular knitting machine disclosed in Chinese Patent Application No.: 201310078290.7, due to the T-slot set therein, the T-shaped slider needs to be pulled out from its upper end or lower end during the replacement of the slider, so that the replacement of the T-shaped slider requires the equipment to remove the needle disk and other components. The adjustable cam seat is easy to use, and at the same time, the fine adjustment of the cam is achieved by rotating the second adjusting screw, so that the cam installation has high accuracy, thereby improving the weaving quality.

[0031] In addition, the surface of the step portion 4 is provided with an anti-slip pad (not shown in the figure), so that the anti-slip property between the slider 3 and the block 14 is improved. Therefore, under the extrusion of the second adjusting screw 11, the static friction between the slider 3 and the block 14 is increased, thereby improving the installation firmness of the slider 3.

[0032] During the weaving process, a wider triangle needs to be set in the processes such as floating line or loop forming to support the formation of the weaving process. By cooperating with two conventional triangle seats set side by side and two conventional triangles, or by cooperating with two conventional triangle seats and a conventional triangle spanning the two conventional triangle seats, the density of the woven fabric is small due to the large width dimension, and the quality of the product is relatively poor. By cooperating with a single conventional triangle seat and a single conventional triangle, it is difficult to form a floating line or loop forming process due to the small width dimension. However, a new triangle with a suitable width cannot be installed on a conventional single triangle seat or two conventional triangle seats. However, a new triangle adapted to the new triangle cannot be installed on a conventional single triangle seat or two conventional triangle seats. However, a conventional triangle cannot be installed on a new triangle that is adapted to the new triangle.

[0033] Therefore, the following settings are adopted to adapt to the installation of the new type of triangle and the conventional two triangles:

[0034] The base 1 is provided with two slide grooves 2, and the two slide grooves 2 are arranged side by side, so that the number of sliders 3 is four, which are distributed as a first slider 31, a second slider 32, a third slider 33 and a fourth slider 34. The first slider 31 and the second slider 32 are located in the same slide groove 2, and the first slider 31 is distributed on the upper side of the second slider 32. The third slider 33 and the fourth slider 34 are located in the same slide groove 2, and the third slider 33 is distributed on the upper side of the fourth slider 34. The first groove 8 and the second threaded hole 10 located at the first slider 31 are symmetrically distributed with the first groove 8 and the second threaded hole 10 located at the second slider 32. The first groove 8 and the second threaded hole 10 located at the third slider 33 are arranged consistently with the first groove 8 and the second threaded hole 10 located at the fourth slider 34. The first groove 8 and the second threaded hole 10 located at the first slider 31 are rotationally symmetrically distributed with the first groove 8 and the second threaded hole 10 located at the third slider 33, and the second threaded hole 10 located at the fourth slider 34 is distributed at the third clamping block 143.

[0035] Furthermore, the two step portions 4 of the first slider 31, the second slider 32 and the fourth slider 34 are located at both ends thereof in the vertical direction, and the two step portions 4 of the third slider 33 are located at the vertical upper end and the vertical middle thereof respectively;

[0036] Furthermore, there are four clamping blocks 14, namely a first clamping block 141, a second clamping block 142, a third clamping block 143 and a fourth clamping block 144. The first clamping block 141 is trussed on the step portion 4 at the vertical upper ends of the first slider 31 and the third slider 33. The second clamping block 142 is trussed on the step portion 4 at the vertical lower ends of the second slider 32 and the fourth slider 34. The third clamping block 143 is trussed on the step portion 4 at the vertical lower end of the first slider 31, the vertical upper end of the second slider 32 and the vertical upper end of the fourth slider 34. The fourth clamping block 144 is trussed on the step portion 4 at the vertical middle part of the third slider 33. The first mounting hole 6 on the first slider 31 and the first mounting hole 6 on the third slider 33 are alternately distributed. The first mounting hole 6 on the second slider 32 and the first mounting hole 6 on the fourth slider 34 are alternately distributed.

[0037] As a result, the structure of the base 1 is compact, and two conventional triangles and a single new triangle can be installed side by side, and used in conjunction with a conventional triangle seat, with a wide range of applications, and the slider and the block can be easily installed, and the installation stability is good, thereby improving the convenience of use.

[0038] In addition, four sliders 3 are arranged on the cam seat. Compared with the commonly used Asian method in which one cam is fixed on one slider, it is necessary to adjust and calibrate the position of the needle exit cam and the flat needle cam, which is difficult to adjust and inefficient. In Europe, the flat needle is not adjustable, or the flat needle cam and the needle exit and half needle cam are locked on the same slider. The adjustment speed is fast, but the variety of fabrics that can be produced is poor. Our cam seat combines the advantages of these two methods, and locks the flat needle cam, the half needle cam and the needle exit cam separately on different sliders. When changing the type of fabric, the flat needle can be adjusted separately, and the needle exit and half needle can also be adjusted separately. The disadvantages of the Asian cam seat with each cam being adjusted separately and the European cam seat with the flat needle being unadjustable are avoided.

[0039] It is worth noting that in the conventional equipment operation vibration, in addition to the vibration of the slider 3, when the slider 3 acts on the inner end of the second adjusting screw 11, it is easy to cause the second adjusting screw 11 to loosen, thereby causing the adjustment accuracy of the second adjusting screw 11 to deviate, resulting in a decrease in the quality of the woven fabric.

[0040] Therefore, a disk body 15 is fixedly provided at the outer end of the second adjusting screw 11, and a plurality of positioning holes 16 are evenly provided around the bottom surface of the disk body 15. Two second mounting holes 17 are provided on the back side of the base 1 and around the second threaded hole 10. A second spring 18 and a positioning rod 19 are provided in each of the second mounting holes 17. After the second adjusting screw 11 is screwed into the second threaded hole 10, the positioning rod 19 abuts against the positioning hole 16 of the disk body 15 under the action of the second spring 18, thereby locking the second adjusting screw 11 and preventing the second adjusting screw 11 from rotating, thereby improving the connection stability of the second adjusting screw 11. When the second adjusting screw 11 is manually adjusted, the positioning hole 19 acts on the positioning rod 19 to squeeze the second spring 18, so that the positioning rod 19 is separated from the positioning hole 16 and embedded in another positioning hole 16, thereby generating a damping feeling and a knocking sound, which can improve the user's adjustment feel and the accuracy of the adjustment, and facilitate the user to perceive the adjustment amount.

[0041] The disk body 15 is provided with a scale 20 to improve the accuracy of adjustment; the side of the disk body 15 is provided with an anti-skid convex strip 21 to improve the anti-skid property and improve the effect of use.

[0042] A fourth threaded hole 22 is provided on the side of the disk body 15 , and a screw is threadedly connected to the fourth threaded hole 22 . The inner end of the screw abuts against the side of the second adjusting screw 11 , thereby facilitating the fixing of the disk body 15 .

[0043] In this embodiment, a third mounting hole 23 is provided on the back side of the base 1, and a first positioning groove 24 is distributed on the bottom surface of the base 1 along the lateral direction. The third mounting hole 23 is connected to the first positioning groove 24, and a second positioning groove 25 is provided at the lower end of the front side of the base 1. During installation, the first positioning groove 24 and the second positioning groove 25 cooperate with the base of the device to achieve positioning, and the third mounting hole 23 is locked to the base of the device located at the first positioning groove 24, thereby improving the firmness of the installation of the base 1 and the convenience of installation.

[0044] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, it should be understood by those skilled in the art that various changes may be made to the present invention in form and details without departing from the spirit and scope of the present invention as defined by the appended claims, all of which are within the scope of protection of the present invention.
