Description

Technical Field

[0001] This utility model relates to the field of spinning, and in particular to a tooling fixture for twisting yarns in chemical fiber pre-spinning equipment. Background Technology

[0002] Chemical fiber pre-spinning equipment is a key piece of equipment in the chemical fiber production process. It is mainly used to prepare nascent fibers from high molecular polymers (such as polyester, polyamide, polypropylene, etc.) through processes such as melting, spinning, and cooling.

[0003] In chemical fiber production, plying in spinning equipment refers to combining single strands of filament into one during spinning or post-processing to improve fiber strength, uniformity, or special properties. Plying can be applied to both pre-spinning and post-spinning processes.

[0004] Existing twisting tooling fixtures are large in size and require a certain amount of space, making them unsuitable for installation and use in confined spaces. Moreover, they have limited functionality, requiring individual adjustment of the slots through which the wire passes during single-strand / twisted conversion. Due to the large number of strands in the wire, this adjustment process is time-consuming and labor-intensive, significantly reducing work efficiency. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a tooling fixture for yarn twisting in chemical fiber pre-spinning equipment, so as to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a tooling fixture for yarn stranding in a chemical fiber pre-spinning equipment, comprising a base plate, a fixing block fixedly mounted on one end of the base plate, a guide plate mounted on the top of the fixing block, and several guide grooves formed on the guide plate, and a support fixedly mounted on the other end of the base plate, wherein a platform is rotatably connected to the support, wherein the platform includes a U-shaped block, two guide rods and multiple carrier blocks, the two guide rods being vertically mounted on the U-shaped block, the multiple carrier blocks being slidably sleeved on the two guide rods, each carrier block having a column mounted on it, and a slot being formed between two adjacent columns for passing two strands of yarn, and a linkage mechanism being provided between the multiple carrier blocks to push the first carrier block to make the multiple carrier blocks fit together to reduce the slot gap for stranding.

[0007] Preferably, the linkage mechanism includes a pin assembly and a pull ring assembly. Each of the carrier blocks is provided with a pin assembly, and a pull ring assembly is sleeved between adjacent pins. When the first carrier block is pulled to the edge of the U-shaped block, an equidistant interval is formed between several carrier blocks.

[0008] Preferably, the pin assembly includes a first pin, a second pin, and a third pin, and the pull ring assembly includes a first pull ring, a second pull ring, and a third pull ring. The first pin is threaded onto the front of the carrier block. Starting from the first carrier block, every two first pins are installed, with a gap of one carrier block between them, and so on. A first pull ring is fitted onto two adjacent first pins. The two second pins are threaded onto the rear middle of the carrier block. Starting from the second carrier block, every two second pins are installed, with a gap of one carrier block between them, and so on. A second pull ring is fitted onto two adjacent second pins. The third pin is threaded onto the upper and lower rear ends of the carrier block. Starting from the third carrier block, every two third pins are installed, with a gap of one carrier block between them, and so on. A third pull ring is fitted onto two adjacent third pins.

[0009] Preferably, a tie rod is connected to one side of the first carrier block, and one end of the tie rod passes through the U-shaped block and the support.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. The twisting tooling fixture of this utility model has a compact structure, which can realize the twisting operation in any space in the spinning equipment, and meet the needs of use in narrow spaces; and the twisting block, column and linkage mechanism are rotatably mounted on the support, so that they are in a corresponding or misaligned state with the guide plate, which can meet the conversion between the guide and the twisting tooling fixture, and improve the functionality and practicality of the twisting tooling fixture.

[0017] 2. This utility model has a linkage mechanism on the carrier block for stranding. Under the action of the linkage mechanism, multiple columns are brought closer together to reduce the gap between the slots, and the spacing between the two strands of silk is merged into half of the original spacing, thereby merging the two strands of silk in the slot into one.

[0026] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0027] This utility model provides tooling fixtures for yarn stranding in pre-spinning equipment for chemical fibers, such as... Figure 1-6 As shown, it includes a base plate 1, a fixing block 2, a wire guide plate 3, a support rod 4, a support 5, a platform 6, a column 7, a tie rod 8, and a protective shell 9.

[0028] The installation structure is as follows: a fixing block 2 is fixedly installed at one end of the substrate 1, a wire guide plate 3 is assembled on the top of the fixing block 2, and several wire guide grooves are opened on the wire guide plate 3. A support 5 is fixedly installed at the other end of the substrate 1, and a platform 6 is rotatably connected to the support 5.

[0029] Specifically, the platform 6 includes a U-shaped block 61, two guide rods 62, and multiple carrier blocks 63. The two guide rods 62 are vertically mounted on the U-shaped block 61, and the multiple carrier blocks 63 are slidably sleeved on the two guide rods 62. Each carrier block 63 is equipped with a column 7, and a slot is formed between two adjacent columns 7 for passing two strands of wire. A linkage mechanism is also provided between the multiple carrier blocks 63, which pushes the first carrier block 63 to make the multiple carrier blocks 63 fit together to reduce the gap between the slots for stranding.

[0030] Before use, the fixture is in an extended state. The upper wire passes through the guide groove of the guide plate and then enters the slot formed between the two columns, so that every two wires pass through one slot. When the wires are combined, the first carrier block is pushed. Under the action of the linkage mechanism, multiple carrier blocks 63 are brought into contact, thereby bringing two adjacent columns 7 closer together to reduce the gap between the slots. The spacing between the two wires is merged into half of the original wire spacing, thus merging the two wires in the slot into one. At the same time, the linkage mechanism can also make multiple columns unfold synchronously, which can easily realize the conversion of wires into strands / single strands. This replaces the traditional operation that requires adjusting the spacing one by one. It is convenient to operate and improves work efficiency.

[0031] For example, 24 strands of 150D yarn can be combined into 12 strands of 300D yarn. The number of strands and the size of the yarn can be customized according to the user's needs. It can also be 12, 16, 32, 48 strands, etc. This can easily achieve the conversion between 150D yarn and 300D yarn. The size of the yarn after combining is doubled, and the number of strands is reduced by half.

[0032] It can be explained here that, in its initial state, the tooling is in a relaxed state, meaning the two columns 7 maintain an initial gap. At this time, the columns on the carrier block 63 are perpendicular to the base plate 1. During stranding, the columns are brought together, and it can be used as a stranding device. Simultaneously, the rotatable platform 6 is parallel to the base, meaning the columns are retracted, preventing the wire from passing through the grooves formed by the columns. In this case, the wire only passes through the guide plate, and it can be used as a wire guide to guide the wire through various parts of the machine along a specific path. This allows for the conversion between a stranding fixture and a wire guide, improving the functionality of the tooling fixture.

[0033] The tooling fixture features an integrated design of the yarn guiding structure and the twisting structure, making it compact and allowing for twisting operations in any space within the spinning equipment, thus meeting the needs of use in confined spaces.

[0034] In this embodiment, the linkage mechanism includes a pin assembly and a pull ring assembly. Each carrier block 63 is provided with a pin assembly, and a pull ring assembly is sleeved between adjacent pins. When the first carrier block 63 is pulled to the edge of the U-shaped block 61, an equidistant interval is formed between several carrier blocks 63.

[0035] Specifically, the pin assembly includes a first pin 64, a second pin 66, and a third pin 68, and the pull ring assembly includes a first pull ring 65, a second pull ring 67, and a third pull ring 69. The first pin 64 is threaded onto the front of the carrier block 63. Starting from the first carrier block 63, every two first pins 64 are installed, skipping one carrier block 63, and so on. A first pull ring 65 is fitted onto two adjacent first pins 64. The two second pins 66 are threaded onto the rear middle of the carrier block 63. Starting from the second carrier block 63, every two second pins 66 are installed, skipping one carrier block 63, and so on. A second pull ring 67 is fitted onto two adjacent second pins 66. The third pin 68 is threaded onto the upper and lower rear ends of the carrier block 63. Starting from the third carrier block 63, every two third pins 68 are installed, skipping one carrier block 63, and so on. A third pull ring 69 is fitted onto two adjacent third pins 68.

[0036] It can be noted that the first pin 64, the second pin 66, and the third pin 68 are the same size, as are the first pull ring 65, the second pull ring 67, and the third pull ring 69, so that the spacing between them remains the same when they are pulled.

[0037] The principle is as follows:

[0038] When the first carrier block 63 moves toward the edge of the U-shaped block 61, the first pin 64 on the second carrier block 63 is pulled by the first pull ring 65, so that the second carrier block 63 moves with the first carrier block 63, and the distance between them is the length of the first pull ring 65.

[0039] When the second carrier block 63 moves, the second pin 66 on the third carrier block 63 is pulled by the second pull ring 67, so that the third carrier block 63 moves with the second carrier block 63, and the distance between them is the length of the second pull ring 67.

[0040] When the third carrier block 63 moves, the third pin 68 on the fourth carrier block 63 is pulled by the third pull ring 69, so that the fourth carrier block 63 moves with the third carrier block 63, and the distance between them is the length of the third pull ring 69.

[0041] When the fourth carrier block 63 moves, the first pin 64 on the fifth carrier block 63 is pulled again by the first pull ring 65, so that the fifth carrier block 63 moves with the fourth carrier block 63, and the distance between them is the length of the first pull ring 65. This process continues until the first carrier block 63 can no longer move. At this time, the same distance is formed between the multiple carrier blocks 63.

[0042] In this embodiment, a pull rod 8 is connected to one side of the first carrier block 63, and one end of the pull rod 8 passes through the U-shaped block 61 and the support 5. The pull rod 8 is used to push or pull the first carrier block 63.

[0043] In this embodiment, a 90-degree arc groove is provided on one of the supports 5. One end of the pull rod 8 passes through the arc groove and slides in contact with it. Pushing 8 can rotate the rotatably connected platform 6 by 90 degrees, so that the platform 6 can rotate from a vertical state to a state parallel to the base, thereby realizing the conversion between stranded wire and guide wire.

[0044] In this embodiment, a protective shell 9 is also provided on the outer side of the platform 6. A rectangular slot through which the column 7 passes is opened on the top surface of the protective shell 9. The protective shell 9 is used to protect the platform 6 and prevent dust and other impurities from entering, so as not to affect the movement between the blocks.

[0045] In this embodiment, a support rod 4 is rotatably connected to the fixing block 2. The support rod 4 is parallel or perpendicular to the wire guide plate 3 along the connecting axis. Before use, the support rod is rotated parallel to the wire guide plate and placed above the wire guide plate for threading, so that the wire passes through the wire guide plate. In use, the support rod is rotated parallel to the base.

[0046] In this embodiment, the column 7 is made of ceramic material.

[0047] In this embodiment, the guide plate 3 is made of ceramic material.

[0048] In other embodiments, the wire guide plate 3 may also be made of metal, depending on the needs of the enterprise.

[0049] Several points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
