Description

Technical Field

[0001] The present application relates to the technical field of textile machinery, and in particular to a two-for-one twisting machine and textile equipment. Background Art

[0002] The two-for-one twister is a kind of textile machinery used for twisting fine yarn. It makes the yarn more compact by twisting two or more strands of fiber yarn, enhances the performance of the original yarn, and reduces the problems of fiber shortening and yarn looseness. Two or more strands of single yarn can be twisted and bonded into strands. Usually, multiple two-for-one twisters are used at the same time to realize the parallel operation of multiple strands of fiber yarn.

[0003] The principle of the two-for-one twister is based on the interaction between yarn elasticity and friction. The electric spindle drives the spindle to rotate to control the multiple spiral rotations of the yarn. The friction between two or more strands of yarn will cause the yarn to twist, and finally form a yarn with a higher twist. At present, when the two-for-one twister is working, the yarn is usually exposed on the outside. When the electric spindle and the yarn rotate, the yarn needs to overcome the air resistance to rotate, which will increase the power consumption of the electric spindle. Summary of the invention

[0036] Referring to FIG. 1 , the present application provides a two-for-one twisting machine 100. FIG. 1 is a schematic diagram of the structure of a two-for-one twisting machine 100 of an embodiment of the present application. The two-for-one twisting machine 100 is applied to textile equipment, and it makes the yarn 210 more compact by twisting two or more strands of fiber yarn 210, thereby enhancing the performance of the original yarn and reducing the problems of fiber shortening and loose yarn 210. The principle of the two-for-one twisting machine 100 is based on the interaction between the elasticity and friction of the yarn 210. The electric spindle drives the spindle 122 to rotate to control the multiple spiral rotations of the yarn 210 and the friction between the two or more strands of yarn 210 will cause the yarn 210 to twist, and finally form a yarn 210 with a higher twist.

[0037] It is understandable that when the current two-for-one twister is working, the yarn is usually exposed to the outside. When the electric spindle and the yarn rotate, the yarn needs to overcome the air resistance to rotate, which will increase the power consumption of the electric spindle. To this end, the present application provides a new type of two-for-one twister 100, which can isolate the airflow in the rotating space from the outside air, so that when the yarn 210 rotates, it only drives the airflow in the rotating space to rotate, reducing the wind resistance of the yarn 210, achieving the purpose of rectification, thereby achieving the purpose of reducing the power consumption of the spindle motor 121, so as to ensure the performance of the two-for-one twister 100. The specific structure of the two-for-one twister 100 of an embodiment is introduced below.

[0038] Referring to FIGS. 1 to 3 , in one embodiment, the two-for-one twisting machine 100 includes a fixed seat 110, a driving assembly 120 and a fairing 130. The driving assembly 120 includes a spindle motor 121 and a spindle 122. The spindle motor 121 is disposed on the fixed seat 110, and the spindle 122 is disposed on the spindle motor 121 and is used to install a bobbin 200. The fairing 130 is disposed on the fixed seat 110 and covers the spindle 122 and the bobbin 200. The top of the fairing 130 has a wire hole 131, and the yarn 210 of the bobbin 200 is led out of the fairing 130 through the wire hole 131. The fairing 130 is used to enclose a rotating space so that the airflow in the rotating space is isolated from the outside air. The spindle motor 121 can drive the spindle 122 to drive the bobbin 200 and the yarn 210 to rotate in the fairing 130. FIG. 2 is a schematic diagram of the two-for-one twister 100 shown in FIG. 1 without the fairing 130 , and FIG. 3 is a force analysis diagram of the yarn 210 in the two-for-one twister 100 shown in FIG. 1 .

[0039] The fixed base 110 is the mounting base of the entire two-for-one twister 100. The fixed base carries the various components of the two-for-one twister 100, so that the two-for-one twister 100 forms an integral structure. Moreover, the fixed base 110 is also installed on the mounting base of the textile equipment, and the two-for-one twister 100 is installed on the mounting base as a whole through the fixed base 110. Optionally, the fixed base 110 is arranged in a flat plate shape. Of course, in other embodiments of the present application, the fixed base 110 can also be a bracket or other structural form of a seat body that can be installed and fixed.

[0040] Optionally, the fixing seat 110 and the mounting base are an integrated structure. That is to say, the driving assembly 120 of the two-for-one twister 100 is directly arranged on the mounting base, and the fairing 130 is also directly arranged on the mounting base. In this way, the number of parts can be reduced, the assembly process can be reduced, and installation and use are convenient. Of course, in other embodiments of the present application, the fixing seat 110 and the mounting base can also be separately arranged, and the fixing seat 110 is fixed to the mounting base by screws or the like.

[0041] The driving assembly 120 is the power source of the two-for-one twister 100. The yarn drum 200 is sleeved on the outside of the driving assembly 120, and the driving assembly 120 can drive the yarn drum 200 to rotate. It can be understood that the yarn 210 to be twisted is wound around the outside of the yarn drum 200, and the yarn 210 also passes through the driving assembly 120 and extends out of the driving assembly 120. When the driving assembly 120 drives the yarn drum 200 to rotate, the yarn drum 200 can drive the yarn 210 to rotate. In this way, the yarns 210 in multiple two-for-one twisters 100 can be paralleled to achieve the purpose of two-for-one twisting.

[0042] Specifically, the driving assembly 120 includes a spindle motor 121 and a spindle 122. The spindle motor 121 is fixedly arranged on the fixing seat 110, the spindle 122 is arranged at the output end of the spindle motor 121, and extends along the height direction of the spindle motor 121, and the yarn drum 200 is fixedly sleeved on the spindle 122. When the spindle motor 121 is working, the spindle motor 121 can drive the spindle 122 to rotate at a high speed, and then the spindle 122 can drive the yarn drum 200 and the yarn 210 to rotate synchronously at a high speed, and the yarn 210 can realize the twisting operation of the yarn 210 when the yarn 210 rotates at a high speed. One end of the yarn 210 passes through the spindle 122 and is located outside the yarn drum 200, and the yarn 210 also extends from the top of the two-for-one twister 100 to perform a parallel operation with the yarn 210 of other two-for-one twisters 100. The height direction in this application is shown in Figure 1, and the height direction is also the axial direction of the spindle motor 121.

[0043] It can be understood that the spindle motor 121 can drive the yarn 210 to rotate at high speed through the spindle 122. The higher the speed of the spindle 122, the higher the efficiency. Usually, the speed can reach 10,000 / minute. The vertically upward yarn 210 also rotates at high speed through the spindle 122. At the same time, due to the action of centrifugal force, the yarn 210 throws out an air circle, and then the yarn 210 can disturb the airflow outside the yarn tube 200, and overcome the resistance of the airflow to drive the airflow to rotate, which will increase the headwind air resistance encountered by the yarn 210 when rotating, thereby increasing the power consumption of the spindle motor 121.

[0044] To this end, the present application sets a fairing 130 on the outer side of the driving assembly 120, and the end of the fairing 130 is fixed to the fixed seat 110. The fairing 130 is hollow, and the interior of the fairing 130 is a rotating space, and the spindle motor 121 is located in the rotating space, and the spindle 122 and the yarn drum 200 are rotatably arranged in the rotating space, and the fairing 130 can separate the airflow in the rotating space from the outside air outside the fairing 130. The top of the fairing 130 has a wire hole 131, and the wire hole 131 passes through the rotating space along the axial direction of the spindle motor 121. After the yarn 210 extends from the spindle 122, it is located between the yarn drum 200 and the fairing 130, and extends from passing through the wire hole 131.

[0045] When the spindle motor 121 drives the spindle 122 to drive the bobbin 200 to rotate at high speed, the yarn 210 can be driven to rotate synchronously at high speed in the fairing space of the fairing 130. Since the fairing 130 can isolate the airflow in the rotating space from the outside air outside the fairing 130, the yarn 210 can drive the airflow in the fairing 130 to rotate when rotating at high speed, but will not drive the outside air outside the fairing 130 to rotate, so as to reduce the wind resistance overcome by the yarn 210 when rotating, thereby reducing the power consumption of the spindle motor 121.

[0046] It is understandable that the yarn forming the balloon in the traditional two-for-one twisting machine is usually subjected to two forces, the force F1 that the spindle 122 drives the yarn 210 forward and the resistance F2 of the air facing the yarn 210. When the fairing 130 is added to the outer side of the yarn tube 200 and the yarn 210, it is equivalent to the yarn 210 rotating in a semi-closed rotating space. When the yarn 210 rotates, it can drive the airflow in the rotating space to rotate synchronously, so that the rotating airflow generates an additional force F3, which can offset part of the resistance F2, thereby achieving the purpose of reducing the power consumption of the spindle motor 121. Practical experiments have shown that after adding the fairing 130 to the outer side of the drive assembly 120 and the yarn tube 200, the power consumption of the spindle motor 121 can be reduced by about 20%, as shown in Figure 3.

[0047] The double twister 100 of the above embodiment is provided with a fairing 130 on the outer side of the spindle 122 and the yarn tube 200, and the fairing 130 is used to isolate the airflow in the internal rotating space from the outside air. When the spindle motor 121 drives the spindle 122 to drive the yarn tube 200 and the yarn 210 to rotate in the fairing 130, the yarn 210 can drive the airflow in the rotating space to rotate synchronously, and will not drive the outside air outside the fairing 130 to rotate. Moreover, when the yarn 210 drives the airflow in the rotating space to rotate, it can generate additional force to offset part of the wind resistance and achieve the purpose of rectification, thereby achieving the purpose of reducing the power consumption of the spindle motor 121, so as to ensure the performance of the double twister 100.

[0048] Referring to FIGS. 1 to 3 , in one embodiment, the spindle 122 includes a spindle disc 1221 and a lining spindle 1222. The spindle disc 1221 is disposed at the output end of the spindle motor 121. The lining spindle 1222 is disposed at the spindle disc 1221 and extends along the axial direction of the spindle motor 121. The yarn tube 200 is sleeved on the lining spindle 1222. The spindle disc 1221 is disc-shaped and disposed at the output end of the spindle motor 121. The lining spindle 1222 is disposed at the spindle disc 1221. The lining spindle 1222 has a certain height in the height direction. The lining spindle 1222 is used to fix and support the yarn tube 200. When the spindle motor 121 is working, the spindle motor 121 can drive the spindle disc 1221 to rotate, the spindle disc 1221 can drive the lining spindle 1222 to rotate synchronously, and then the lining spindle 1222 can drive the yarn tube 200 to rotate synchronously.

[0049] Referring to Fig. 1, in one embodiment, the backing spindle 1222 and the spindle plate 1221 have a wire passage 1223, and the yarn 210 of the yarn tube 200 passes through the wire passage 1223 and extends out of the spindle 122, and through the wire hole 131 and extends out of the fairing 130. The wire passage 1223 is a routing channel for the yarn 210, and the wire passage 1223 is arranged in the middle of the backing spindle 1222 and extends along the height direction of the backing spindle 1222, and the wire passage 1223 also passes through the side of the spindle plate 1221. One end of the yarn 210 of the yarn drum 200 extends from the top of the backing spindle 1222 into the wire passage 1223, and extends from the bottom spindle plate 1221 to the outside of the yarn drum 200 through the wire passage 1223. In addition, the yarn 210 also extends upward from between the yarn drum 200 and the fairing 130, and extends from the wire hole 131 at the top of the fairing 130. In this way, the layout of the routing of the yarn 210 is completed. The yarn 210 extending out of the fairing 130 is guided by the balloon yarn guide.

[0050] Referring to Fig. 1, in one embodiment, there is a preset distance between the rotating yarn 210 and the inner wall of the fairing 130. That is, when the spindle 122 drives the bobbin 200 and the yarn 210 to rotate, the yarn 210 is located between the bobbin 200 and the fairing 130 and rotates between the bobbin 200 and the fairing 130, and the yarn 210 will open in a direction away from the bobbin 200 under the action of centrifugal force and form an air ring. At this time, it is necessary to ensure that there is a certain distance between the yarn 210 and the inner wall of the fairing 130 to avoid the yarn 210 from contacting the inner wall of the fairing 130 when rotating, thereby reducing the wear of the yarn 210 and ensuring the quality of the yarn 210.

[0051] 1 and 4 , in one embodiment, the fairing 130 includes a sleeve 132, the sleeve 132 covers the spindle 122 and the yarn drum 200, and the bottom of the sleeve 132 is fixed to the fixing seat 110. FIG4 is a schematic diagram of the fairing 130 in the two-for-one twister 100 shown in FIG1 . The sleeve 132 is the main structure of the fairing 130. After the sleeve 132 covers the spindle 122 and the yarn drum 200, the sleeve 132 is located outside the yarn drum 200 and has a certain distance from the yarn drum 200. The yarn 210 is located between the yarn drum 200 and the inner wall of the sleeve 132.

[0052] The sleeve 132 can be separated in the radial direction to isolate the airflow in the rotating space from the outside air. At this time, the top opening of the sleeve 132 is a wire hole 131, and the yarn 210 extends through the wire hole 131 at the top of the sleeve 132. When the spindle motor 121 drives the spindle 122 to drive the yarn tube 200 and the yarn 210 to rotate in the sleeve 132, the yarn 210 can drive the airflow in the rotating space to rotate synchronously, and will not drive the outside air outside the sleeve 132 to rotate and can generate additional force to offset part of the wind resistance, achieve the purpose of rectification, and thus achieve the purpose of reducing the power consumption of the spindle motor 121. That is, the resistance encountered by the yarn 210 during rotation can also be reduced through a separate sleeve 132 to reduce the power consumption of the spindle motor 121.

[0053] Referring to Fig. 1 and Fig. 4, in one embodiment, the sleeve 132 is in a hollow cylindrical shape. That is, the sleeve 132 is in a structure of equal diameter. Of course, in other embodiments of the present application, the sleeve 132 may also be in an ellipsoidal shape or other regular or irregular shapes, as long as a certain distance is ensured between the yarn 210 and the interior of the sleeve 132.

[0054] Referring to Fig. 1 and Fig. 4, in one embodiment, the fairing 130 further includes a top cover 133, which is arranged on the top of the sleeve 132, and the wire hole 131 is arranged on the top cover 133. The top cover 133 is arranged on the top of the sleeve 132, and the top cover 133 has a through wire hole 131. After the top cover 133 and the sleeve 132 cover the spindle 122 and the yarn tube 200, the top cover 133, the sleeve 132 and the fixing seat 110 are arranged to form a semi-enclosed rotating space. When the spindle motor 121 drives the spindle 122 to drive the yarn tube 200 and the yarn 210 to rotate in the sleeve 132, the yarn 210 can drive the airflow in the rotating space to rotate synchronously, and will not drive the external air outside the sleeve 132 to rotate and can generate additional force to offset part of the wind resistance, so as to achieve the purpose of rectification, thereby achieving the purpose of reducing the power consumption of the spindle motor 121. That is, the combination of the sleeve 132 and the top cover 133 can better reduce the resistance encountered by the yarn 210 during rotation, so as to further reduce the power consumption of the spindle motor 121.

[0055] 1 and 4 , in one embodiment, the shape of the top cover 133 matches the shape of the top of the yarn tube 200. In this way, the overall size of the fairing 130 can be reduced, and the size of the rotating space can be reduced to reduce the power consumption of the yarn 210. At the same time, the overall size of the two-for-one twister 100 can also be reduced, and the occupied space of the two-for-one twister 100 can be reduced.

[0056] Referring to FIG. 1 and FIG. 4 , in one embodiment, the axial height of the sleeve 132 is less than or equal to the height of the drive assembly 120. In other words, the overall height of the sleeve 132 is slightly less than the overall height of the drive assembly 120. In this way, after the top cover 133 is arranged on the sleeve 132, the drive assembly 120 can be covered on the top, so that the fairing 130 can cover the drive assembly 120 and the yarn bobbin 200 as a whole. Moreover, there is a preset distance between the inner wall of the sleeve 132 and the drive assembly 120, so that the yarn 210 can be ensured not to contact the inner wall of the sleeve 132 and the top cover 133 when rotating, so as to avoid the wear of the yarn 210 and ensure the quality of the yarn 210.

[0057] Referring to FIG. 1 and FIG. 4 , in one embodiment, the sleeve 132 and the top cover 133 are an integral structure. That is, the sleeve 132 and the top cover 133 are formed by an integral molding method. In this way, the number of parts of the fairing 130 can be reduced to reduce the assembly process. At the same time, the overall structural strength of the fairing 130 can be ensured, thereby ensuring the performance of the fairing 130. Of course, in other embodiments of the present application, the sleeve 132 and the top cover 133 can also be separately provided and fixed by gluing or threaded connection, as long as the structural strength of the fairing 130 is ensured.

[0058] 1 and 2, in one embodiment, the fairing 130 further has an operation opening and a switch door 140, wherein the operation opening penetrates the fairing 130 in the radial direction of the spindle 122, and the switch door 140 is provided on the fairing 130 to open or close the operation opening. The operation opening is provided on the sleeve 132, and the operation opening can connect the rotation space of the fairing 130 with the external ring.

[0059] The switch door 140 can open or close the operation opening. When the switch door 140 opens the operation opening, the fairing 130 can expose the spindle 122 and the yarn drum 200 inside through the operation opening. At this time, the parts in the rotating space can be operated, such as replacing the yarn drum 200, adjusting the position of the yarn drum 200, etc., so as to facilitate the operation of the operator. When the switch door 140 closes the operation opening, the operation opening can be shielded. At this time, the fairing 130 can have a rectifying effect. Moreover, when the two-for-one twister 100 is stopped, the switch door 140 is operated to open or close the operation opening.

[0060] It is worth noting that the location of the switch door 140 on the fairing 130 is not limited in principle, and it can be set on the front or side of the fairing 130 as long as it is easy for the operator to operate and does not interfere with the adjacent two-for-one twister 100 or other components.

[0061] In one embodiment, the switch door 140 is rotatably mounted on the fairing 130 via a rotating shaft, so that the switch door 140 opens or closes the operation opening. In other words, the switch door 140 is rotatably mounted on the fairing 130, and the operation opening can be exposed when the switch door 140 is rotated to open, and the operation opening can be covered when the switch door 140 is rotated to close.

[0062] Of course, in other embodiments of the present application, the switch door 140 is detachably mounted on the fairing 130 through a fixing member, so that the switch door 140 opens or closes the operation opening. Exemplarily, the switch door 140 can be detachably mounted on the switch door 140 through a buckle, a latch, etc.

[0063] In one embodiment, the fairing 130 is made of a transparent material. In this way, the operator can directly observe the working conditions of the internal spindle motor 121, the spindle 122 and the bobbin 200 through the transparent fairing 130, so as to facilitate the operation of the operator. Of course, in other embodiments of the present application, the fairing 130 has a transparent observation window. In this way, the operator can directly observe the working conditions of the internal spindle motor 121, the spindle 122 and the bobbin 200 through the transparent observation window, so as to facilitate the operation of the operator.

[0064] In one embodiment, the two-for-one twister 100 further includes a supporting component, which is installed between the fairing 130 and the spindle 122, and is used to rotatably support the spindle 122 and the fairing 130. The supporting component plays a supporting role, so that the spindle 122 can rotate relative to the fairing 130 through the supporting component to ensure the smooth rotation of the spindle 122, thereby reducing the shaking of the spindle 122 and the bobbin 200 during rotation, and ensuring the dynamic balance during rotation.

[0065] Exemplarily, the support component is a support bearing. The inner ring of the support component is sleeved on the spindle 122 and rotates synchronously with the spindle 122. The outer ring of the support component is installed on the fairing 130. The spindle 122 can drive the inner ring of the support component to rotate relative to the outer ring, so that the spindle 122 can rotate smoothly and ensure dynamic balance during rotation.

[0066] The two-for-one twister 100 of the above-mentioned embodiment is provided with a fairing 130 on the outer side of the spindle 122 and the yarn tube 200, and the fairing 130 is used to isolate the airflow in the internal rotating space from the outside air. When the spindle motor 121 drives the spindle 122 to drive the yarn tube 200 and the yarn 210 to rotate in the fairing 130, the yarn 210 can drive the airflow in the rotating space to rotate synchronously, reducing the wind resistance of the yarn 210 and achieving the purpose of rectification, thereby achieving the purpose of reducing the power consumption of the spindle motor 121, so as to ensure the performance of the two-for-one twister 100.

[0067] The present application also provides a textile device, comprising a mounting base and a plurality of two-for-one twisters 100 as described in any of the above embodiments, wherein the plurality of two-for-one twisters 100 are arranged in rows and columns on the mounting base. Optionally, the mounting base is an integral structure to carry each two-for-one twister 100. After the textile device of the present application adopts the plurality of two-for-one twisters 100 of the above embodiments, the yarn 210 can be paralleled, and the power consumption of the entire device can be reduced to ensure the performance of the textile device.

[0068] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
