Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile fabric cutting technology, specifically a textile fabric cutting size positioning device. Background Technology
[0002] Textile fabrics are materials used to make clothing. During the production and processing of textile fabrics, they need to be cut to size. Various auxiliary equipment is used in the processing of textile fabrics, and the most frequently used of these auxiliary equipment is the positioning device for cutting textile fabrics.
[0003] In existing technology, steel needles are used to fix the textile fabric to the operating table to complete the positioning of the textile fabric. However, positioning the textile fabric requires the use of multiple steel needles, which need to be inserted into the textile fabric one by one and inserted into the operating table. When cutting another textile fabric, the steel needles need to be removed and re-inserted, which is time-consuming. In addition, when inserting steel needles, the textile fabric needs to be pulled and straightened after each steel needle is inserted, which further slows down the processing efficiency. Therefore, it is necessary to improve the textile fabric cutting size positioning device to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a textile fabric cutting size positioning device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a textile fabric cutting size positioning device, including an operating table, an installation frame provided on the outside of the operating table, a lifting threaded rod rotatably installed inside the installation frame, a lifting rod installed on the external thread of the lifting threaded rod, a bidirectional threaded rod rotatably installed inside the lifting rod, and two pressure rods installed on the external thread of the bidirectional threaded rod, with steel needles fixedly installed at the bottom of each of the two pressure rods.
[0006] Preferably, the pressure rod is slidably mounted inside the lifting rod, and the lifting rod is slidably mounted up and down inside the mounting frame.
[0007] Preferably, each of the two pressure rods has a rotating shaft rotatably mounted inside, a rotating frame is fixedly mounted outside the rotating shaft, a smoothing roller is rotatably mounted inside the rotating frame, and two coil springs are fixedly mounted outside the rotating shaft.
[0008] Preferably, the end of the coil spring away from the rotating shaft is fixedly installed with the pressure rod. The coil spring is initially in a wound state. A limit groove is formed inside the pressure rod, and the rotating frame is movably installed inside the limit groove.
[0009] Compared with the prior art, the present invention provides a textile fabric cutting size positioning device, which has the following beneficial effects:
[0010] 1. This textile fabric cutting size positioning device allows the distance between two pressure rods to be adjusted according to the size of the textile fabric through a bidirectional threaded rod. When cutting textile fabric of the same size, there is no need to make repeated adjustments, making the device more convenient to operate and improving the processing efficiency of textile fabric.
[0011] 2. Based on this, the present invention uses a lifting threaded rod to drive the steel needle to descend and fix the textile fabric to the top of the operating table, thereby completing the rigid positioning of the textile fabric, so that the textile fabric will not shift during subsequent cutting and improving cutting accuracy.
[0012] 3. Based on this, the present invention uses a coil spring to make the smoothing roller roll on the top of the textile fabric for auxiliary positioning, thereby further enhancing the cutting accuracy. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0020] Example 1:
[0021] Please see Figure 1-3 This utility model provides a technical solution: a textile fabric cutting size positioning device, including an operating table 1, an installation frame 2 on the outside of the operating table 1, a lifting threaded rod 3 rotatably installed inside the installation frame 2, a lifting rod 4 threaded on the outside of the lifting threaded rod 3, a bidirectional threaded rod 5 rotatably installed inside the lifting rod 4, and two pressure rods 6 threaded on the outside of the bidirectional threaded rod 5. Steel needles 7 are fixedly installed at the bottom of each of the two pressure rods 6, so as to fix the textile fabric on the top of the operating table 1, thereby completing the rigid positioning of the textile fabric.
[0022] Furthermore, the pressure rod 6 is slidably installed inside the lifting rod 4, and the lifting rod 4 is slidably installed inside the mounting frame 2, so that the pressure rod 6 drives the steel needle 7 to rise and fall smoothly, and the positioning effect is better.
[0023] Example 2:
[0024] Please see Figure 1-3 Furthermore, in conjunction with Embodiment 1, it is further found that the two pressure rods 6 are each rotatably mounted with a rotating shaft 8 inside, the rotating shaft 8 is fixedly mounted with a rotating frame 9 outside, the rotating frame 9 is rotatably mounted with a smoothing roller 10 inside, and the rotating shaft 8 is fixedly mounted with two coil springs 11 outside, so that within a certain lifting distance, the smoothing roller 10 can perform auxiliary positioning of the textile fabric.
[0025] Furthermore, the end of the coil spring 11 away from the rotating shaft 8 is fixedly installed with the pressure rod 6. The coil spring 11 is initially in a wound state. A limit groove is opened inside the pressure rod 6, and the rotating frame 9 is movably installed inside the limit groove to limit the rotation range of the rotating frame 9, thereby making the auxiliary positioning effect of the textile fabric better.
[0026] In actual operation, when this device is in use, the mounting bracket 2 can be bolted to the outside of the operating table 1, allowing the device to be installed and disassembled according to usage. This enables the mounting bracket 2 and its connected components to switch between use and storage, providing greater flexibility. Then, the bidirectional threaded rod 5 is rotated, and the two pressure rods 6, threaded onto the outside of the bidirectional threaded rod 5, move synchronously in opposite directions. When the two pressure rods 6, carrying two sets of steel needles 7, reach the appropriate position according to the size of the textile fabric, the rotation of the bidirectional threaded rod 5 stops. At this time, the lifting threaded rod 3 is rotated, causing the lifting rod 4 to descend, thereby causing the two pressure rods 6 to lower the two sets of steel needles 7, fixing the textile fabric to the top of the operating table 1, thus completing the process. The rigid positioning of paired textile fabrics prevents them from shifting during subsequent cutting, improving cutting accuracy. The coil spring 11 is initially in a wound state, at which point the rotating frame 9 is tilted, and the bottom of the smoothing roller 10 is lower than the bottom of the steel needle 7. When the pressure bar 6 descends, the smoothing roller 10 first contacts the textile fabric. As the pressure bar 6 continues to descend, the rotating frame 9 rotates around the rotating shaft 8, thereby driving the smoothing roller 10 to roll to both sides to pre-position the textile fabric, making it easier for the steel needle 7 to be inserted when descending. At the same time, the smoothing roller 10 can also pre-treat the textile fabric, making it lay flat on the top of the operating table 1, further enhancing cutting accuracy.
[0027] It should be added that when new textile fabric needs to be cut, rotating the lifting threaded rod 3 causes the lifting rod 4 to rise. At this time, the steel needle 7 disengages from the textile fabric. At the same time, the coil spring 11 rewinds and drives the rotating frame 9 to rotate, so that the smoothing roller 10 always rolls above the textile fabric, making it faster for the steel needle 7 to disengage from the textile fabric.
[0028] It should be noted that the distance between the two pressure rods 6 can be adjusted according to the size of the textile fabric. When cutting textile fabric of the same size, the textile fabric can be positioned simply by rotating the lifting threaded rod 3. The operation is simple and quick, avoiding the problem that the existing technology requires the insertion of multiple steel needles 7 for positioning, and the steel needles 7 need to be repeatedly inserted for removal and replacement, which is time-consuming. This improves the processing efficiency of textile fabric.
[0029] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
