Description

Technical Field

[0001] The utility model belongs to the technical field of textile equipment, and in particular relates to a false twister component which is easy to replace. Background Art

[0002] The false twist machine is a kind of textile processing equipment, which is mainly used to false-twist and deform the silk thread, so as to improve its gloss, softness, elasticity and other qualities. The working principle of the false twist machine is to use the friction between the silk thread and the false twister to make the silk thread false-twist and deform under the action of traction; specifically, the false twist machine fixes the two ends of the silk thread, uses the false twister to rotate to generate friction, and makes the silk thread generate rotational torque, thus forming a false twist effect.

[0003] The false twister on the false twisting machine is usually composed of an active shaft, a passive shaft and a plurality of wheels thereon. The silk thread moves between the wheels, and the shaft drives the wheels to rotate, thereby completing the false twisting of the silk thread.

[0004] The discs may be worn or damaged during use. The silk thread will not be able to achieve the false twisting effect on the silk thread when it runs between the worn or damaged discs, and may even be damaged. Therefore, the discs need to be replaced. However, on the current false twister, the discs and the shaft are connected by a fixed connection or by a screw and nut. When replacing, the shaft and the discs need to be replaced together, which increases the maintenance cost of the equipment. If only the damaged discs are replaced, the discs need to be removed from the shaft one by one, replaced with new discs, and then installed one by one. Due to the installation method of the discs and the shaft, the disassembly process is cumbersome and difficult, and it is likely to cause damage to other discs on the shaft that do not need to be replaced.

Detailed implementation manner

[0062] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0063] Embodiment 1

[0064] A false twisting device assembly that is convenient for replacement, comprising: a base 1, a driving shaft rod 2, a first driven shaft rod 3, a second driven shaft rod 4, a working disc 5, an import disc 6, an export disc 7, a limiting structure, and a wheel disc clamping structure;

[0065] As Figure 4 shown, three vertically penetrating shaft rod channels 102 are opened on the base 1. From a top view, the three shaft rod channels 102 are arranged in a "pin" shape, that is, the three shaft rod channels 102 are respectively opened at the three vertices of an equilateral triangle.

[0066] As Figure 1 shown, the driving shaft rod 2 is detachably arranged in the rear shaft rod channel 102, the first driven shaft rod 3 is detachably arranged in the left front shaft rod channel 102, and the second driven shaft rod 4 is detachably arranged in the right shaft rod channel 102.

[0067] The active shaft 2, the first driven shaft 3 and the second driven shaft 4 are provided with a limit seat 201, the shaft part above the limit seat 201 is used to set the wheel of the false twister, and the shaft part below the limit seat 201 is used to insert into the shaft passage 102 of the false twister base 1; the limit seat 201 is used to divide the above two parts, after the shaft below the limit seat 201 on the active shaft 2 is inserted into the shaft passage 102 in the base 1, the part extends from the bottom of the base 1, that is, the lower end opening of the shaft passage 102, and the extended part is connected to the driving motor. After the shaft below the limit seat 201 of the first driven shaft 3 and the second driven shaft 4 is inserted into the shaft passage 102 in the base 1, the part is completely located in the shaft passage 102.

[0068] like Figure 1 As shown, two working discs 5 are arranged on the driving shaft 2 from top to bottom; two export discs 7 are arranged on the first driven shaft 3 from top to bottom; three import discs 6 are arranged on the second driven shaft 4 from top to bottom; the working discs 5 and a part of the export discs 7 are staggered between the three import discs 6; Fig.10 As shown, the arrangement relationship structure between the working disk 5, the export disk 7 and the import disk 6 is shown in the front view.

[0069] The active shaft 2 rotates under the action of the driving motor, driving the working disk 5 thereon to rotate. Under the action of friction, the working disk 5 drives the introduction disk 6 and the export disk 7 to rotate; the silk thread passes through the working disk 5, the introduction disk 6 and the export disk 7 to complete the false twisting operation.

[0070] The above base 1, active shaft 2, first driven shaft 3, second driven shaft 4, working disc 5, inlet disc 6 and outlet disc 7 all belong to the structure on the existing false twister; the specific structure of the base 1 and the installation structure of the base 1 and the false twister belong to the prior art and do not belong to the structure improved by the present application, so they will not be repeated again.

[0071] In the structure of the prior art, the working disc 5, the introduction disc 6 and the export disc 7 are all fixedly welded and mounted on their respective shafts, or are mounted on their respective shafts through some mechanical fastening structures; during the use of the false twister, if one or several of the wheels are severely worn, they need to be replaced; either the entire shaft and the wheels need to be replaced, which increases the cost of equipment maintenance, and the wheels that can still be used are replaced, resulting in material waste; or the mechanical fastening structures need to be disassembled one by one, the wheels need to be removed from the shaft, and the wheels that need to be replaced are replaced, and then the wheels are installed one by one, making the replacement and maintenance process of the wheels cumbersome, and the wheels may also be damaged during the process of disassembling the mechanical fastening structures.

[0072] Therefore, in this embodiment, the shaft rod and the wheel disc are configured as two independent components, which are detachably assembled and used as a whole; the shaft rod passes through the through hole in the center of the wheel disc, and the wheel disc is set on the shaft rod, and the position of the wheel disc is fixed on the shaft rod by the wheel disc clamping structure provided on the shaft rod; through the limiting structure, when the shaft rod rotates, the wheel disc can rotate synchronously.

[0073] like Figure 5 As shown, the limiting structure in this embodiment is configured as a wheel disc clamping groove 301 and a clamping protrusion;

[0074] The wheel disc fixing grooves 301 are vertically opened on the side walls of the driving shaft 2, the first driven shaft 3 and the second driven shaft 4, and two grooves are symmetrically arranged on the side walls of the shafts;

[0075] The inner walls of the central through holes of the working disc 5, the inlet disc 6 and the outlet disc 7 are provided with fixing protrusions corresponding to the wheel fixing grooves 301;

[0076] When installing the wheel on the shaft, the locking protrusion is embedded in the wheel locking groove 301 and the wheel is set on the shaft; in this way, when the shaft rotates, the wheel can rotate with the shaft under the cooperation of the wheel locking groove 301 of the limiting structure and the locking protrusion.

[0077] like Figure 5 As shown, the above-mentioned roulette wheel fixing structure is arranged on each shaft rod from top to bottom, and the number of groups of roulette wheel fixing structures is consistent with the number of roulette wheels currently arranged on the shaft rod; a roulette wheel is detachably fixed to a group of roulette wheel fixing structures.

[0078] A set of wheel disc fixing structures includes four elastic clamps 204, which are movably arranged on the outer wall of each shaft rod; two elastic clamps 204 are arranged on the upper side, and the other two elastic clamps 204 are arranged on the lower side; the upper and lower two elastic clamps 204 are symmetrically arranged on the shaft rod. The spacing between the upper and lower elastic clamps 204 is equal to the thickness of the wheel disc.

[0079] When installing the wheel, you only need to clamp the lower elastic clamp 204 on the lower bottom of the wheel and clamp the upper elastic clamp 204 on the upper surface of the wheel; in this way, the wheel can be fixed on the shaft by using the upper and lower elastic clamps 204. When removing the wheel, you only need to press the elastic clamp 204 to retract the elastic clamp 204 into the shaft, so that the wheel can be quickly removed; the elastic clamp 204 is easy to operate and does not have other complicated mechanical fixing structures, making the entire removal or installation of the wheel faster.

[0080] like Figure 8As shown, a spring nail groove 2041 is provided in the outer wall of the driving shaft 2, the first driven shaft 3 and the second driven shaft 4; the opening position of the spring nail groove 2041 should be the position for installing the elastic staple 204;

[0081] An elastic staple 204 is movably arranged in the elastic staple groove 2041; one end of the elastic staple 204 located in the elastic staple groove 2041 is connected to the rear side of the elastic staple groove 2041 through an elastic member 2042; the elastic member 2042 is configured as a spring;

[0082] When the elastic member 2042 does not undergo elastic deformation, the elastic staple 204 partially extends out of the elastic staple slot 2041, and the extended portion of the elastic staple 204 serves to fix the wheel disc on the shaft. The elastic staple 204 is pressed inwardly, and the elastic member 2042 is compressed. As the degree of compression increases, the elastic staple 204 can be completely pressed into the elastic staple slot 2041, and the wheel disc can be disassembled.

[0083] Example 2

[0084] Based on Example 1, in Example 1, the wheel disc is fixed to the shaft by elastic staples 204; the wheel disc can be disassembled and replaced conveniently and quickly; however, Figure 5 As shown in , if the top wheel is to be replaced, it is only necessary to remove the top wheel and then replace it; if the middle or bottom wheel needs to be removed and replaced, the upper wheels need to be removed one by one; and because the wheels on each shaft are staggered, it may be necessary to remove the wheel on the adjacent shaft before the target wheel can be removed; although the removal of the wheels is easier, there are more wheels that need to be removed and restored, and the operation process is still relatively long.

[0085] like Figure 6 as well as Figure 7 As shown, in this embodiment, the driving shaft 2, the first driven shaft 3 and the second driven shaft 4 are configured to be composed of a plurality of independent segmented shafts 202; the segmented shafts 202 are connected end to end to form a complete shaft.

[0086] like Figure 6 The figure shows an exploded view of the segmented shaft 202 of the second driven shaft 4. A total of three segmented shafts 202 are arranged above the stop seat 201. A square rod 206 is arranged on the bottom surface of each segmented shaft 202. A square hole 205 is arranged on the upper end surface of the second and third segmented shafts 202 and the upper end surface of the stop seat 201.

[0087] like Figure 7The figure shows an exploded view of the segmented shaft 202 of the driving shaft 2 and the first driven shaft 3. The portion above the limit seat 201 is provided with three segmented shafts 202 in total. The lower bottom surfaces of the first and second segmented shafts 202 are provided with square rods 206, and the upper end surfaces of the second and third segmented shafts 202 are provided with square hole grooves 205.

[0088] The square rod 206 is disassembled and arranged in the square hole groove 205, that is, the segmented shaft rods 202 are assembled into a complete shaft rod;

[0089] like Figure 6 As shown, a supporting flange 203 is provided on the lower bottom edge of the first to third segmented shafts 202 of the second driven shaft 4, and an elastic clamp 204 is provided above the supporting flange 203; the distance between the supporting flange 203 and the elastic clamp 204 is equal to the thickness of the wheel disc;

[0090] like Figure 7 As shown, supporting flanges 203 are also provided on the lower bottom edges of the first and second segmented shafts 202 of the driving shaft 2 and the first driven shaft 3, and elastic staples 204 are provided above the supporting flanges 203; the spacing between the supporting flanges 203 and the elastic staples 204 is equal to the thickness of the wheel disc.

[0091] The elastic staples 204 are movably disposed on the side wall of the segmented shaft 202 , and the two elastic staples 204 are symmetrically disposed.

[0092] The wheel disc is mounted on the segmented shaft 202, with the supporting flange 203 supporting and limiting the wheel disc at the bottom, and the elastic clamp 204 clamping the wheel disc at the top of the wheel disc, so that the position of the wheel disc on the shaft remains fixed.

[0093] When the wheel disc needs to be replaced, it is only necessary to separate the segmented shaft rod 202 on which the wheel disc is installed from the upper segmented shaft rod 202, and the wheel disc can be removed from the upper part; there is no need to remove the wheel discs one by one and then install them one by one after the replacement is completed. The same is true for the wheel disc that is blocked by the side shaft rod, and it is only necessary to remove the segmented shaft rod 202 on which the wheel disc is installed, without removing the wheel disc; after the replacement is completed, it is only necessary to connect the segmented shaft rod 202; the whole process is faster and easier to disassemble and assemble.

[0094] Example 3

[0095] Based on the embodiment 1, in the embodiment 1, each shaft is provided with a stopper 201, and after the shaft is inserted into the base 1, the stopper 201 prevents the shaft from slipping out of the base 1 from below along the shaft passage 102. However, the shaft can be easily pulled out from the top of the base 1 together with the wheel.

[0096] like Figure 2As shown, a clamping seat 8 is movably mounted on the outside of the limiting seat 201; the upper part of the limiting seat 201 can extend from the upper end of the clamping seat 8, and the lower part of the limiting seat 201 is clamped in the clamping seat 8; by installing the clamping seat 8 on the base 1, the limiting clamping of the limiting seat 201 by the clamping seat 8 can be achieved, and the entire shaft rod can be limited to prevent the shaft rod from being pulled out from above the base 1.

[0097] A circular threaded fixing groove is provided in the fixing seat 8, such as Figure 3 As shown, when the shaft is installed on the base 1, a threaded convex edge 101 is provided on the outer periphery of the limiting seat 201, and the threaded convex edge 101 is provided on the upper surface of the base 1;

[0098] The clamping seat 8 is screwed to insert the threaded flange 101 into the threaded clamping groove in the clamping seat 8 , so that the clamping seat 8 can be fixed on the upper surface of the base 1 . The clamping seat 8 limits the limiting seat 201 to prevent the shaft rod from being pulled out of the base 1 .

[0099] Example 4

[0100] Based on Example 1, in Example 1, the working disc 5, the introduction disc 6 and the output disc 7 rotate with friction with each other, and the silk thread passes between the discs. Under the rotation of the discs, the silk thread is falsely twisted. The side wall of the disc that directly contacts the silk thread is easy to cause the disc to fail due to wear and needs to be replaced as a whole; and the part that is actually worn is only the side of the disc.

[0101] like Fig. 9 As shown, in this embodiment, the working disk 5, the introduction disk 6 and the output disk 7 are all configured to be composed of a disk base 501 and a friction sleeve 502; the friction sleeve 502 is made of elastic rubber, silicone and other materials; the friction sleeve 502 can be put on the outer wall of the disk base 501 by pulling;

[0102] A plurality of convex strips 5011 are arranged on the outer wall of the disk base 501; a plurality of grooves 5021 are arranged on the inner wall of the friction sleeve 502; the friction sleeve 502 is sleeved on the disk base 501, and the convex strips 5011 are embedded in the grooves 5021. Through the cooperation between the convex strips 5011 and the grooves 5021, the friction sleeve 502 can rotate synchronously with the rotation of the disk base 501.
