Technical Field

[0001] This utility model belongs to the field of needle rollers for opening machines, and specifically relates to a highly adaptable needle bar structure. Background Technology

[0002] The needle roller of an opening machine is an important component, mainly used in the textile industry to open fibers. Through the needle bars (or teeth) on the needle roller, clumps of fibers can be effectively separated, making them looser and more uniform, thus providing high-quality raw materials for subsequent processing such as spinning.

[0003] In existing technologies, traditional needle bar structures typically consist of vertically arranged needle bars that are directly fixed to the mounting device. However, traditional designs have certain limitations in practical use, especially when facing different materials and processing requirements, where their adaptability and efficiency often fail to fully meet the needs. Furthermore, traditional needle bar structures struggle to accommodate different working angles and force requirements, leading to poor performance under certain operating conditions. Therefore, overcoming these technical problems and shortcomings is a key issue that needs to be addressed. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects described in the background art, thereby realizing a highly applicable needle bar structure to solve the problems of traditional needle bar structures being upright, difficult to accommodate different working angles, low adaptability, and large limitations in the use of existing needle bar structures.

[0005] To achieve the above-mentioned utility model objectives, the technical solution of this utility model is: a highly applicable needle bar structure, including an installation roller, a needle bar seat, and needle bars, wherein the needle bars are arranged in a longitudinally inclined manner on the needle bar seat, and the needle bar seat is detachably arranged in a circumferential array on the installation roller.

[0006] Specifically, the mounting roller has a threaded hole, and the needle bar seat has a positioning hole corresponding to the threaded hole of the mounting roller. The needle bar seat is fixed to the threaded hole of the mounting roller by bolts.

[0007] Preferably, the needle holder is semi-cylindrical in shape, with a semi-circular cross-section.

[0008] Meanwhile, a concave groove is provided at the bottom plane of the needle bar seat, and the threaded hole is opened perpendicularly to the concave groove.

[0009] In the above-mentioned highly adaptable needle bar structure, the needle bar seat is provided with a needle bar hole, which is opened vertically or at an angle. When the needle bar hole is opened at an angle, the angle between the axis of the needle bar hole and the vertical line is 20°-25°.

[0010] Specifically, the end of the needle bar is fixedly embedded in the needle bar hole.

[0011] Specifically, the upper part of the needle bar is pointed and the lower part is columnar. The tip of the pointed part is chamfered. Both the needle bar and the needle bar seat are polished as a whole. The columnar part of the needle bar is fixedly embedded in the needle bar hole.

[0012] Furthermore, the distance between the tip of the needle bar and the bottom of the needle bar seat is 43mm-44mm.

[0013] Preferably, the angle between the axis of the needle bar hole and the vertical line is 22.5°.

[0014] Meanwhile, the distance between the tip of the needle bar and the bottom of the needle bar seat is 43.3 mm.

[0015] In the above-mentioned highly adaptable needle bar structure, the diameter of the needle bar seat is 30mm-35mm, the positioning hole is an embedded hole with a larger upper part and a smaller lower part, the upper diameter of the positioning hole is 15mm-20mm and the depth is 7mm-10mm, the lower diameter of the positioning hole is 5mm-10mm, and its depth extends to the top of the positioning hole and to the bottom of the upper concave groove.

[0016] Preferably, the needle holder has a diameter of 34mm, the upper part of the positioning hole has a diameter of 16mm and a depth of 8mm, and the lower part of the positioning hole has a diameter of 9mm.

[0017] The beneficial effects of this utility model are:

[0018] 1. The highly adaptable needle bar structure of this utility model, through the adoption of an inclined needle bar installation method and a detachable needle bar seat structure, significantly improves the adaptability of the needle bar assembly to different materials and processing techniques. The needle bar hole is set to an optional inclined shape, allowing the needle bar to flexibly adjust the contact angle and force according to the opening requirements of different fiber materials, thereby maintaining good separation effect and working efficiency even when dealing with fine, easily tangled, or high-strength fibers.

[0019] 2. The needle bar of this invention features a chamfered upper tip and maintains a precise distance from the bottom of the needle bar holder, ensuring optimal working length and stability when penetrating materials. Simultaneously, the entire needle bar holder is polished to reduce surface friction and prevent damage to the fiber material. This improves opening efficiency while effectively protecting fiber integrity and subsequent processing quality. Furthermore, the modular needle bar holder design allows users to quickly change needle bar combinations of different specifications according to actual needs, achieving efficient and precise processing.

[0020] 3. This utility model adopts a split mounting roller and needle bar seat structure.

[0033] The highly adaptable needle bar structure of this utility model will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0034] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0035] Example 1

[0036] This embodiment discloses a highly adaptable needle bar structure. By setting a split mounting roller needle bar seat structure and an inclined needle bar mounting method, it solves the problems of traditional needle bar structures being vertical, difficult to accommodate different working angles, and having low adaptability and significant limitations when used in the prior art; see the following for details.

[0037] See Figure 2 It mainly includes an installation roller 1, a needle bar seat 2 and a needle bar 3. The needle bars 3 are arranged in a longitudinally inclined manner on the needle bar seat 2, and the needle bar seat 2 is detachably arranged in a circumferential array on the installation roller 1.

[0038] In this embodiment, the mounting roller 1 is the basic component of the entire needle bar structure, and all other components are mounted on the mounting roller 1. The needle bar holder 2 is the intermediate component that supports the needle bar 3. By mounting the needle bar through the needle bar holder 2, the fixation of the needle bar 3 can be ensured, and the needle bar 3 can be disassembled and replaced relative to the mounting roller 1. By replacing the needle bar holder 2 with needle bars 3 of other models, the applicability can be met during use.

[0039] To enable the detachable replacement of the needle holder 2, see [link / reference]. Figure 3 , Figure 4 The mounting roller 1 has a threaded hole, and the needle bar seat 2 has a positioning hole 201 corresponding to the threaded hole of the mounting roller 1. The needle bar seat 2 is fixed to the threaded hole of the mounting roller 1 by bolts.

[0040] In this embodiment, the threaded hole on the mounting roller 1 is aligned with the positioning hole 201 on the needle bar seat 2, and then fixed with bolts. This ensures sufficient fastening force to maintain stability during operation, while also facilitating quick disassembly when replacement or maintenance is required.

[0041] Additionally, it should be noted that in actual use, depending on the actual usage, a limiting groove can be opened on the outer surface of the mounting roller 1, or a limiting rail can be added. A limiting block adapted to the limiting groove or a sliding groove adapted to the limiting rail can be set at the bottom of the needle bar seat 2 to achieve a detachable connection between the needle bar seat 2 and the mounting roller 1.

[0042] See Figure 5The needle bar holder 2 has a needle bar hole 203, which can be vertical or inclined. When the needle bar hole 203 is inclined, the angle between the axis of the needle bar hole 203 and the vertical line is 20°-25°. The end of the needle bar 3 is fixedly embedded in the needle bar hole 203.

[0043] By setting the tilt angle, the needle bar 3 can more effectively contact and loosen the fiber material during the opening process. This helps to separate the fiber material from its aggregated state while reducing damage to the fibers, thereby improving opening efficiency and fiber processing quality. The advantages are particularly pronounced when processing fine or easily tangled fiber materials.

[0044] In this embodiment, the needle bar 3 is divided into two parts: an upper tip 301 and a lower columnar part 302. The tip 301 is used to penetrate and process materials, and its top end is chamfered to reduce penetration resistance and improve accuracy. The columnar part 302 provides necessary support and stability to ensure that the needle bar 3 maintains the correct position and orientation during operation.

[0045] The aforementioned structure enables the needle bar 3 to exhibit excellent performance when processing various materials. By optimizing the shape and angle of the tip 301, as well as the size and surface treatment of the columnar portion 302, the needle bar 3 can adapt to different working environments and requirements.

[0046] To allow the bolt to be embedded through the positioning hole, the needle bar seat 2 is fixed to the mounting roller 1, see [reference]. Figure 4 The diameter of the needle bar seat 2 is 30mm-35mm. The positioning hole 201 is an embedded hole with a larger upper part and a smaller lower part. The upper diameter of the positioning hole 201 is 15mm-20mm and the depth is 7mm-10mm. The lower diameter of the positioning hole 201 is 5mm-10mm. Its depth extends to the top of the positioning hole 201 and to the bottom of the upper concave groove 202.

[0047] In this embodiment, the positioning hole 201 is designed as an insert-type hole that is larger at the top and smaller at the bottom to facilitate the insertion and fixing of bolts. This structure allows bolts or fasteners with larger heads to easily enter and provides guidance and support.

[0048] The lower diameter of the positioning hole 201 is small, ranging from 5mm to 10mm, and its depth extends from the top to the upper part of the positioning hole 201, and from the bottom directly to the upper recessed groove 202. This design allows the bolts of the slender portion to be tightly embedded, thereby ensuring a firm connection between the needle bar seat and the mounting roller.

[0049] The unequal diameter design not only helps guide the bolts into correct position but also enhances the stability of the fixation, effectively preventing loosening due to vibration or other external forces. Furthermore, the embedded bolts prevent the mounting rollers from interfering with the opening and loosening of the pins during operation, ensuring the proper opening and loosening effect of the pins.

[0050] Example 2

[0051] The similarities to the above embodiments will not be repeated, the differences are as follows:

[0052] See Figure 3 , Figure 4 , Figure 6 The needle holder 2 is generally semi-cylindrical with a semi-circular cross-section. A concave groove 202 is provided on the bottom plane of the needle holder 2, and the threaded hole is perpendicular to the concave groove 202.

[0053] In this embodiment, the needle holder 2 is generally semi-cylindrical with a semi-circular cross-section. The semi-cylindrical shape of the needle holder 2 reduces the resistance of the mounting roller 1 during operation. A concave groove 202 is provided on the bottom plane of the needle holder 2. This groove reduces the weight of the needle holder, decreases material usage, and while reducing weight, maintains the structural strength, service life, and stability of the needle holder.

[0054] In addition, in this embodiment, the concave groove 202 is a through groove. In actual implementation, according to production needs, a liquid delivery pipeline can be added inside the concave groove 202 to reduce the heat generated by the friction of the mounting roller 1 driving the needle bar seat 2 and needle bar 3 for a long time, thereby maintaining the temperature stability of each component and avoiding deformation of the needle bar 3 due to overheating and long-term operation, thus ensuring the service life of the needle bar 3.

[0055] Example 3

[0056] The similarities with the above embodiments and their combinations will not be repeated, the differences being:

[0057] See Figure 4 , Figure 5 The angle between the axis of the needle bar hole 203 and the vertical line is 22.5°, and the distance between the tip of the needle bar 3 301 and the bottom of the needle bar seat 2 is 43.3 mm. Meanwhile, the needle bar seat 2 has a diameter of 34 mm, the upper diameter of the positioning hole 201 is 16 mm, the depth is 8 mm, and the lower diameter of the positioning hole 201 is 9 mm.

[0058] In this embodiment, the angle between the axis of the needle bar hole 203 and the vertical line is set to 22.5°. This ensures that the needle bar achieves optimal results when processing various materials, increasing penetration and separation efficiency, thereby improving overall work efficiency and quality.

[0059] The distance between the tip 301 of the needle bar 3 and the bottom of the needle bar seat 2 is 43.3 mm (±0.5 mm). This specified length ensures that the needle bar has the optimal operating length during operation, which guarantees sufficient penetration power and avoids inconvenience or reduced efficiency caused by being too long or too short.

[0060] Additionally, it should be noted that in actual implementation, if only some needle bars 3 need to be replaced, the damaged or worn needle bars can be individually removed and replaced from the needle bar holder 2; at the same time, the needle bar combination can be flexibly adjusted according to different working conditions to improve the adaptability of the equipment.

[0061] The working principle of the highly applicable needle bar structure of this utility model:

[0062] In use, the needle bar holder 2 is arranged in a circumferential array and bolted to the outer surface of the mounting roller 1. The mounting roller 1 drives the needle bar holder 2 to rotate, and the needle bars 3 rotate accordingly, loosening the material.

[0063] The inclined needle bar 3 more effectively contacts and separates fibrous materials, especially suitable for fine or easily tangled materials; the chamfered tip 301 enhances the opening accuracy and improves the opening quality.

[0064] When it is necessary to replace the needle bar assembly with a different specification for loosening, loosen the fixing bolts and remove the needle bar seat 2 from the mounting roller 1; select a needle bar seat 2 with different needle bar parameters (such as angle, length, density, etc.) according to different material or process requirements. Arrange the new needle bar seat 2 in a circumferential array on the mounting roller 1, and fix it with bolts again through the positioning hole 201 and the threaded hole.

[0065] It should be noted that, in actual implementation, the structure depicted in the accompanying drawings is not a fixed or unchanging embodiment. The components of the embodiments of this invention described and shown in these drawings can typically be arranged and designed in various different configurations. Furthermore, the accompanying drawings and abstract drawings are merely illustrative and do not represent the specific structure or actual quantity in a concrete implementation.
