Description

Technical Field

[0001] The invention relates to the technical field of two-for-one twisting processing, and in particular to a two-for-one twisted semi-finished product transfer device. Background Art

[0002] Double twisted yarn is to combine single yarns (2 strands, 3 strands, etc.) and then add a certain twist according to the requirements. It is different from the traditional twisting method, which is ring twisting, one turn is one twist, and the yarn twist is relatively uneven. The double twisting machine twists through a dragon belt transmission, one turn has 2 twists (2 twists).

[0003] Since the raw materials for double twisting are mostly yarns, during the transportation of semi-finished products, in order to facilitate the next stage of processing, yarn heads will be reserved on the yarn sleeves to facilitate assembly on processing machinery. However, during the transportation, the yarn sleeves will be affected by external environmental factors and vibrate, so the yarn heads will fall off the surface of the yarn sleeves, causing them to be lost during transportation. If the yarn heads are fixed by knotting or the like, although the yarn heads can be fixed on the surface of the yarn sleeves more stably, in the next round of processing, the process of removing and finding the threads will be more cumbersome, and will also cause additional losses, resulting in an increase in the number of yarn semi-finished products required for the finished product.

[0026] 1. In order to prevent the loss of yarn during transportation, the double-twisted semi-finished product transfer device is provided with an upper fixing mechanism and a lower fixing mechanism on the convex column.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Example 1

[0038] See also Figure 1-Figure 6 A two-for-one twisted semi-finished product transfer device comprises a base 1, a convex column 2 is arranged on the base 1, the convex column 2 is used to place the blank, an upper fixing mechanism and a lower fixing mechanism are respectively arranged on the convex column 2, the upper fixing mechanism and the lower fixing mechanism are respectively arranged on the top and the bottom of the blank, and the upper fixing mechanism and the lower fixing mechanism are used to shield the blank;

[0039] The upper fixing mechanism includes an upper support plate 31 disposed on the top of the convex column 2, and an upper convex rod 32 is movably hinged on the upper support plate 31, and a plurality of upper convex rods 32 are disposed on the upper support plate 31, and the plurality of upper convex rods 32 are connected by an upper connecting film 33;

[0040] The lower fixing mechanism includes a lower support plate 41 arranged at the bottom of the convex column 2, and a lower convex rod 42 is movably hinged on the lower support plate 41. A plurality of lower convex rods 42 are arranged on the lower support plate 41, and the plurality of lower convex rods 42 are connected by a lower connecting membrane 43.

[0041] In the present embodiment: during the transportation of the yarn, the yarn head will become loose on the sleeve due to the vibration generated by the transportation, and then fall off, and the general transportation device does not have the function of fixing or limiting the yarn head. Therefore, in order to prevent the yarn from being lost during the transportation, an upper fixing mechanism and a lower fixing mechanism are respectively provided on the boss 2. When the yarn tube is placed on the boss 2, the top and bottom of the yarn tube can be limited by the upper fixing mechanism and the lower fixing mechanism, so that the area where the yarn head is located is covered, and the yarn head is limited on the sleeve, thereby reducing the possibility of separation from the sleeve due to bumps, thereby reducing the loss of the yarn during transportation.

[0042] The upper fixing mechanism includes an upper support plate 31 arranged on the top of the boss 2, and an upper protruding rod 32 is movably hinged on the upper support plate 31. There are multiple upper protruding rods 32 on the upper support plate 31, and the multiple upper protruding rods 32 are connected by an upper connecting membrane 33.

[0043] The upper fixing mechanism can be separated from the boss 2 to facilitate the installation of the yarn bobbin on the boss 2 for transportation. When the yarn bobbin is installed on the boss 2, the angle of the upper protruding rod 32 on the upper supporting plate 31 is adjusted to change the size of the upper connecting film 33 to make it match the top size of the yarn bobbin, and then the upper fixing mechanism is installed on the boss 2, so that the upper connecting film 33 covers the top of the yarn bobbin, wraps the top of the yarn bobbin, and then covers the yarn head together, and readjusts the angle of the upper protruding rod 32 so that the upper connecting film 33 fits more closely on the yarn bobbin to complete the fixation.

[0044] Since the upper connecting film 33 shields the yarn end and the upper connecting film 33 is adjusted to fit closely on the top of the yarn tube, the yarn end is difficult to separate from the yarn tube during transportation, thereby reducing possible loss.

[0045] Since it cannot be guaranteed that each yarn tube can be positioned at the position where the yarn head is located as the top during transportation and assembly, a lower fixing mechanism is provided on the boss 2. The lower fixing mechanism is used to shield the bottom of the yarn tube. Its working principle is the same as that of the upper fixing mechanism, so it will not be elaborated here. By providing a lower fixing mechanism to deal with the fixation when the yarn head is not at the top position, the practicability of the device is guaranteed.

[0046] In addition, in order to improve the elastic deformation ability of the upper connecting membrane 33 and the lower connecting membrane 43, grooves are provided on the upper connecting membrane 33 and the lower connecting membrane 43. By providing the grooves, the deformable range of the two is increased to meet the assembly requirements.

[0047] Example 2

[0048] See also Figure 2-Figure 3, a first driving mechanism is also provided on the upper support plate 31, and the first driving mechanism is used to drive the upper protruding rod 32 to rotate on the upper support plate 31;

[0049] The first driving mechanism includes a threaded sleeve 51 rotatably arranged on the upper support plate 31, a threaded rod 52 is also slidably arranged in the upper support plate 31, and the threaded sleeve 51 and the threaded rod 52 are threadedly connected. A first connecting rod 53 is also arranged on the threaded rod 52, and the threaded rod 52 is connected to the upper protruding rod 32 through the first connecting rod 53.

[0050] One end of the first connecting rod 53 is movably hinged to the threaded rod 52 through a hinge shaft, and the other end of the first connecting rod 53 is movably hinged to the upper protruding rod 32 through a hinge shaft.

[0051] In this embodiment, a first driving mechanism is provided on the upper fixing mechanism, and the angle of the upper protruding rod 32 can be adjusted by the first driving mechanism to adapt it to the assembly requirements.

[0052] The first driving mechanism includes a threaded sleeve 51 rotatably arranged on the upper support plate 31, a threaded rod 52 is also slidably arranged in the upper support plate 31, and the threaded sleeve 51 and the threaded rod 52 are threadedly connected. A first connecting rod 53 is also arranged on the threaded rod 52, and the threaded rod 52 is connected to the upper protruding rod 32 through the first connecting rod 53.

[0053] By rotating the threaded sleeve 51, the threaded rod 52 threadedly connected thereto can be driven to slide on the upper support plate 31. At this time, since the threaded rod 52 is connected to the upper protruding rod 32 through the first connecting rod 53, when the threaded rod 52 slides on the upper support plate 31 toward the direction close to the protruding column 2, the upper protruding rod 32 can be driven to shrink toward the direction close to the protruding column 2 to complete the fit with the yarn tube. The reverse sliding can make the upper protruding rod 32 expand in the direction away from the protruding column 2 to complete the disassembly and assembly needs.

[0054] Example 3

[0055] See also Figure 2-Figure 3 , an auxiliary fixing assembly is also provided in the upper support plate 31, and the threaded rod 52 is connected to the upper support plate 31 through the auxiliary fixing assembly;

[0056] The auxiliary fixing assembly includes a supporting telescopic rod 61 arranged in the upper fixing mechanism, and a supporting plate 62 is arranged on the threaded rod 52 , and the supporting telescopic rod 61 and the supporting plate 62 are connected.

[0057] The threaded sleeve 51 is also provided with a rotating assembly, and the threaded sleeve 51 is rotatably mounted on the upper support plate 31 through the rotating assembly;

[0058] The rotating assembly includes a rotating block 71 disposed on the threaded sleeve 51 . The threaded sleeve 51 is provided with a rotating groove 72 which is adapted to the rotating block 71 , and the rotating block 71 is slidably disposed in the rotating groove 72 .

[0059] In this embodiment: in order to make the threaded rod 52 slide under the drive of the threaded sleeve 51, an auxiliary fixing component is also provided in the upper support plate 31, and the threaded rod 52 can be limited by the auxiliary fixing component to make its operation more stable.

[0060] The auxiliary fixing assembly includes a supporting telescopic rod 61 arranged in the upper fixing mechanism, and a supporting plate 62 is arranged on the threaded rod 52. The supporting telescopic rod 61 is connected to the supporting plate 62. Through the mutual cooperation between the supporting telescopic rod 61 and the supporting plate 62, the sliding of the threaded rod 52 is more stable.

[0061] In addition, a rotating assembly is also provided on the threaded sleeve 51, through which the threaded sleeve 51 can be rotated on the upper support plate 31 to drive the threaded rod 52 to slide. A rotating block 71 is provided on the threaded sleeve 51, and a rotating groove 72 that is adapted to the rotating block 71 is opened on the upper support plate 31, and the rotating block 71 is slidably arranged in the rotating groove 72. Through the mutual cooperation of the rotating block 71 and the rotating groove 72, the threaded sleeve 51 can be rotated on the upper support plate 31, thereby driving the threaded rod 52 threadedly connected thereto to slide.

[0062] Example 4

[0063] See also Figure 4-Figure 6 , a second connecting rod 13 is also provided on the lower protruding rod 42, and the lower protruding rod 42 is connected to the protruding column 2 through the second connecting rod 13;

[0064] The lower support plate 41 is also provided with a second driving mechanism, which is used to drive the lower protruding rod 42 to rotate on the lower support plate 41;

[0065] The second driving mechanism includes a sliding sleeve 81 slidably disposed in the lower support plate 41 . A sliding abutment plate 82 is also slidably disposed on the boss 2 . The sliding sleeve 81 is used to abut against the sliding abutment plate 82 , and the sliding abutment plate 82 is used to abut against the second connecting rod 13 .

[0066] A limited sliding mechanism is provided on the sliding contact plate 82, and the sliding contact plate 82 is slidably provided on the protruding column 2 through the limited sliding mechanism;

[0067] The limiting sliding mechanism includes a limiting sliding block 91 arranged on the sliding contact plate 82 . A limiting sliding groove 92 which is adapted to the limiting sliding block 91 is formed on the boss 2 . The limiting sliding block 91 is slidably arranged in the limiting sliding groove 92 .

[0068] An auxiliary telescopic rod 10 is also provided in the boss 2 . The auxiliary telescopic rod 10 is used to assist the sliding contact plate 82 in sliding. The boss 2 is connected to the sliding contact plate 82 via the auxiliary telescopic rod 10 .

[0069] In this embodiment: Since the lower fixing mechanism is arranged at the bottom of the boss 2, the lower fixing mechanism is installed on the boss 2 and cannot be driven in the same way as the upper fixing mechanism. Therefore, a second driving mechanism is arranged in the lower support plate 41, and the lower boss 42 is adjusted by the second driving mechanism.

[0070] When the lower protruding rod 42 needs to be adjusted, the sliding sleeve 81 is slid to make it slide along the protruding column 2 toward the second connecting rod 13, so that the sliding sleeve 81 contacts the sliding contact plate 82 on the protruding column 2 and slides toward the second connecting rod 13, and then contacts the second connecting rod 13 to drive the lower protruding rod 42 to change its angle, thereby completing the adjustment.

[0071] In order to make the sliding of the sliding contact plate 82 more stable, a limited sliding mechanism is provided on the sliding contact plate 82 , and the sliding contact plate 82 is slidably connected to the boss 2 via the limited sliding mechanism to limit the sliding of the sliding contact plate 82 .

[0072] The limiting sliding mechanism includes a limiting sliding block 91 arranged on the sliding contact plate 82 . A limiting sliding groove 92 which is adapted to the limiting sliding block 91 is formed on the boss 2 . The limiting sliding block 91 is slidably arranged in the limiting sliding groove 92 .

[0073] Through the mutual adaptation between the limiting sliding block 91 and the limiting sliding groove 92 , the sliding contact plate 82 can slide on the boss 2 more stably.

[0074] It should be noted that a return spring may be provided on the limit slider 91 so that the limit slider 91 and the boss 2 are elastically connected via the return spring. The return spring may accelerate the return of the sliding contact plate 82 when the limit slider 91 loses the contact of the sliding sleeve 81 .

[0075] In order to further stabilize the sliding of the sliding resistance plate 82, an auxiliary telescopic rod 10 is further provided on the lower support plate 41. The lower support plate 41 is also connected to the sliding resistance plate 82 through the auxiliary telescopic rod 10, and the sliding resistance plate 82 is additionally supported by the auxiliary telescopic rod 10.

[0076] Example 5

[0077] See also Figure 4-Figure 5 , the base 1 is also provided with an adjustment mechanism, which is used to make the sliding contact plate 82 slide;

[0078] The adjusting mechanism includes a groove 111 opened on the boss 2, an adjusting resistance block 112 is slidably arranged in the groove 111, the adjusting resistance block 112 is used to resist the sliding resistance plate 82, and a threaded screw 113 is also rotatably arranged in the groove 111, the adjusting resistance block 112 is installed on the threaded screw 113, and the adjusting resistance block 112 and the threaded screw 113 are threadedly connected.

[0079] In this embodiment, in order to drive the sliding sleeve 81 to slide on the base 1, an adjustment mechanism is further provided in the base 1, and the sliding sleeve 81 is adjusted by the adjustment mechanism.

[0080] The adjusting mechanism includes a groove 111 opened on the base 1, in which an adjusting resistance block 112 is slidably arranged, and the adjusting resistance block 112 is used to resist the sliding resistance plate 82. A threaded screw 113 is also rotatably arranged in the groove 111, and the adjusting resistance block 112 is installed on the threaded screw 113, and the adjusting resistance block 112 and the threaded screw 113 are threadedly connected.

[0081] By rotating the threaded screw 113, the adjusting resistance block 112 threadably connected thereto slides in the groove 111, thereby causing it to resist or move away from the sliding sleeve 81. When the adjusting resistance block 112 slides toward the sliding sleeve 81 and resists against the sliding sleeve 81, the sliding sleeve 81 will be resisted by it and slide toward the second connecting rod 13, thereby resisting the sliding resistance plate 82 to resist the second connecting rod 13.

[0082] When the adjusting abutment block 112 slides in a direction away from the sliding sleeve 81 , the sliding sleeve 81 will fall down again under the action of gravity, so that the lower protruding rod 42 will automatically return to its original position under the elastic action of the lower connecting membrane 43 .

[0083] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
