Description

Technical Field

[0001] The invention belongs to the technical field of textile equipment, and in particular relates to a single-sided or double-sided oiling high-precision guide wheel for a two-for-one twisting machine. Background Art

[0002] In the textile industry, the two-for-one twister is an important device for improving the quality of yarn. As a key component of the two-for-one twister, the guide wheel directly affects the twist and uniformity of the yarn. However, the traditional two-for-one twister guide wheel has many deficiencies in lubrication, which leads to a series of problems.

[0003] First, the traditional guide wheel lacks a convenient lubricant adding structure. Textile workers need to regularly disassemble the guide wheel for lubrication, but this process is not only cumbersome, but also increases the downtime of the machine, affecting production efficiency. Secondly, due to uneven lubrication, the different parts of the guide wheel wear to different degrees, which is prone to eccentricity or deformation caused by local wear, which not only affects the twist uniformity of the yarn, but may also damage the yarn and reduce the quality of the textile.

[0004] In addition, the lubricating oil in the traditional lubrication process is prone to overflow or dripping, which will not only contaminate the yarn and textiles, but also the process equipment, increase the cost of cleaning and maintenance, and even cause environmental pollution and unsafe hidden dangers in the workplace. The process of adding lubricating oil is also very inconvenient. Due to the lack of a special lubricating oil filling port or channel, workers need to disassemble the guide wheel or add lubricating oil through a narrow gap. The operation is difficult and the lubrication effect is difficult to guarantee. Especially in large-scale production scenarios, this inconvenience significantly affects work efficiency.

[0005] Furthermore, due to the inconvenience of adding lubricating oil, workers tend to add a large amount of oil at one time to reduce the frequency of adding. This not only causes a waste of lubricating oil, but may also lead to excessive lubricating oil and affect the lubrication effect of the guide wheel, thereby aggravating the wear problem.

[0006] In summary, the traditional two-for-one twister guide wheel has many problems such as high maintenance frequency, uneven lubrication leading to wear, risk of lubricant contamination, difficulty in adding lubricant, and uneconomical use. These problems not only reduce production efficiency, but also increase the maintenance cost and operation difficulty of the equipment. In order to solve these drawbacks, it is urgent to improve the structure of the two-for-one twister guide wheel and design a structure that is convenient for adding lubricant to improve the lubrication effect, reduce maintenance time and cost, and ensure the efficient and stable operation of the guide wheel.

[0007] In view of this, the present invention is proposed. Summary of the invention

[0008] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0009] Single-sided and double-sided oiling high-precision guide wheels for two-for-one twisting machines include:

[0010] Guide wheel;

[0011] The guide wheel is composed of an external wheel body, a roller bearing and a wheel axle;

[0012] The outer wheel body is rotatably arranged on the surface of the wheel axle through a roller bearing;

[0013] The axle includes a unidirectional axle and / or a bidirectional axle;

[0014] One-way shaft:

[0015] The one-way shaft is rotatably arranged on one side of the wheel body through a roller bearing, and a first groove is arranged at one end of the one-way shaft;

[0016] The arc-shaped side wall of the one-way shaft is provided with a plurality of first roller grooves;

[0017] Bidirectional axis:

[0018] The bidirectional shaft passes through the surface of the wheel body through a roller bearing and rotates, and a second groove is formed at both ends and / or one end of the bidirectional shaft;

[0019] The arc-shaped side wall of the bidirectional shaft is provided with a plurality of second roller grooves;

[0020] The first roller groove and the second roller groove are both used to cooperate with the rolling limit of the roller bearing;

[0021] The arc-shaped side wall of the one-way shaft is provided with a plurality of first oil outlets, and the arc-shaped side wall of the two-way shaft is provided with a plurality of second oil outlets.

[0022] Preferably, the first oil outlet is arranged in communication between a plurality of first roller grooves, and the second oil outlet is arranged in communication between a plurality of second roller grooves.

[0023] Preferably, the first groove formed at one end of the one-way shaft extends to the positions of a plurality of first oil outlets, and the first groove is in a communicating state with the plurality of first oil outlets.

[0024] Preferably, when the two ends of the bidirectional shaft are provided with second grooves, the two second grooves extend to a through state and are connected with a plurality of second oil outlets.

[0025] Preferably, the inner wall of the first groove is threadedly fitted with a first short nail and / or a first long nail.

[0026] Preferably, when the bidirectional shaft has a second groove at one end, the second groove is formed through the opening to form a through groove and / or extends to be connected to a plurality of second oil outlets.

[0027] Preferably, a second side hole is formed at one end and / or both ends of the arc-shaped side wall of the bidirectional shaft, and the second side hole is communicated with the second groove.

[0028] Preferably, a second long spike, a second short spike and / or a second seal are provided at one end and / or both ends of the second groove.

[0029] Preferably, the arc-shaped side wall of the one-way shaft is provided with a first side hole connected to the first groove.

[0030] Preferably, the inner walls of the first side hole and the second side hole are provided with plugs.

[0031] Beneficial effects:

[0032] This solution innovates the guide wheel structure of the two-for-one twister and makes special improvements to the wheel axle under the long-term continuous operation conditions of the traditional guide wheel. First, the newly designed first groove, second groove, first side hole or second side hole as the lubricating oil filling channel makes the addition of lubricating oil quick and convenient, without the need to frequently disassemble the guide wheel, reducing the downtime of the machine and thus improving production efficiency. Secondly, the evenly distributed opening of multiple first oil outlets or second oil outlets can evenly disperse the lubricating oil to the surroundings, making the guide wheel more evenly lubricated, effectively reducing the wear of each part, avoiding the eccentricity or deformation of the guide wheel caused by local wear, and fundamentally improving the uniformity of yarn twist and the quality of textiles.

[0033] In addition, the improved lubricant addition structure effectively prevents the spillage and dripping of lubricant, reduces the pollution to yarn and equipment, reduces the cost of cleaning and maintenance, and reduces environmental pollution and unsafe hidden dangers in the workplace. The new structure design allows workers to easily add lubricant through a special filling port or channel, making the operation easier and greatly improving work efficiency.

[0034] More importantly, precise lubricant addition control avoids excessive use of lubricant, reduces waste, and ensures that the guide wheel runs at the optimal amount of oil, further improving the lubrication effect and equipment life. In short, the improved two-for-one twister guide wheel has been significantly improved in terms of lubrication convenience, ease of operation, environmental protection and production efficiency, providing a more efficient and economical solution for the textile industry.

[0051] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0052] like Figures 1 to 6 As shown, the single-sided and double-sided oiling high-precision guide wheel 1 of the two-for-one twisting machine includes:

[0053] The guide wheel 1 is composed of an external wheel body 4, a roller bearing 3 and a wheel axle 2;

[0054] The outer wheel body 44 includes a single-plate protrusion, a double-sided protrusion or a borderless setting.

[0055] The outer wheel body 4 is rotatably arranged on the surface of the wheel axle 2 through the roller bearing 3;

[0056] The wheel axle 2 includes a unidirectional axle 2a or a bidirectional axle 2b;

[0057] The one-way shaft 2a is rotatably arranged on one side of the wheel body through a roller bearing 3, and a first groove 2a3 is arranged at one end of the one-way shaft 2a;

[0058] The arc-shaped side wall of the one-way shaft 2a is provided with a plurality of first roller grooves 2a2;

[0059] The bidirectional shaft 2b passes through the roller bearing 3 and rotates on the surface of the wheel body. The two ends or one end of the bidirectional shaft 2b is provided with a second groove 2b3;

[0060] The arc-shaped side wall of the bidirectional shaft 2b is provided with a plurality of second roller grooves 2b2;

[0061] The first roller groove 2a2 and the second roller groove 2b2 are both used to cooperate with the rolling limit of the roller bearing 3;

[0062] The arc-shaped side wall of the unidirectional shaft 2a is provided with a plurality of first oil outlets 2a4, and the arc-shaped side wall of the bidirectional shaft 2b is provided with a plurality of second oil outlets 2b4.

[0063] The first oil outlet 2a4 is disposed in communication between a plurality of first roller grooves 2a2, and the second oil outlet 2b4 is disposed in communication between a plurality of second roller grooves 2b2.

[0064] The first groove 2a3 formed at one end of the one-way shaft 2a extends to the positions of the plurality of first oil outlets 2a4, and the first groove 2a3 is in communication with the plurality of first oil outlets 2a4.

[0065] When the two ends of the bidirectional shaft 2b are provided with the second grooves 2b3, the two second grooves 2b3 extend to a through state and are connected with a plurality of second oil outlets 2b4.

[0066] The inner wall of the first groove 2a3 is threadedly fitted with the first short nail 2a6 or the first long nail 2a5.

[0067] When the second groove 2b3 is formed at one end of the bidirectional shaft 2b, the second groove 2b3 is formed through the opening to form a through groove or extends to be connected with a plurality of second oil outlets 2b4.

[0068] A second side hole 2b8 is formed at one end or both ends of the arc-shaped side wall of the bidirectional shaft 2b, and the second side hole 2b8 is communicated with the second groove 2b3.

[0069] A second long spike 2b6, a second short spike 2b5 and / or a second seal 2b7 are disposed at one end or both ends of the second groove 2b3.

[0070] The arc-shaped side wall of the one-way shaft 2a is provided with a first side hole 2a8 which is connected with the first groove 2a3.

[0071] The inner walls of the first side hole 2a8 and the second side hole 2b8 are provided with sealing plugs 2b9.

[0072] The single-sided or double-sided oiling high-precision guide wheel 1 of the two-for-one twisting machine of this solution brings significant benefits through a series of optimized designs. First, the guide wheel 1 adopts a single-sided or double-sided oil inlet design, so that the lubricating oil can be evenly distributed to the lubrication part of the guide wheel 1 from multiple oil outlets. This design ensures that the guide wheel 1 is fully lubricated when running at high speed, reduces friction and wear, and thus extends the service life of the guide wheel 1.

[0073] This design greatly reduces the difficulty of maintaining the guide wheel 1. The interconnected design of multiple first oil outlets 2a4, second oil outlets 2b4 and first grooves 2a3, second grooves 2b3 allows workers to easily add lubricating oil through a special refueling port or channel without frequently disassembling the guide wheel 1, reducing the time and complexity of daily maintenance. At the same time, the tip seal 2b9 design ensures that the lubricating oil will not leak, reducing environmental pollution and resource waste, and ensuring the cleanliness and efficiency of the refueling process.

[0074] The guide wheel 1 is made of a combination of carbon fiber and tempered material, which is lightweight, high-strength and has good wear resistance. It can effectively cope with high-load and high-speed working environments, extend the service life of the guide wheel 1, and improve the overall performance of the two-for-one twister. The roller bearing 3 design ensures the stable rotation between the outer wheel body 4 and the wheel axle 2, reduces the wear caused by friction, and further enhances the durability and performance of the guide wheel 1;

[0075] The guide wheel 1 can be made of a high-hardness, wear-resistant material.

[0076] In addition, this solution provides two implementation methods: a unidirectional shaft 2a and a bidirectional shaft 2b. The unidirectional shaft 2a is suitable for the design of a guide wheel 1 with one side fixed, while the bidirectional shaft 2b is suitable for the design that penetrates the wheel body. This diversified design is suitable for two-for-one twisters of different types and specifications, expanding the application range and applicability of the product. The unidirectional shaft 2a and the bidirectional shaft 2b can adapt to different loads and working conditions through the cooperation of the roller groove and the roller bearing 3, ensuring that the guide wheel 1 can operate efficiently under various working conditions.

[0077] By simplifying the lubricant addition process and improving the durability of the guide wheel 1, this solution reduces machine downtime and significantly improves production efficiency. The efficient lubrication and structural durability of the guide wheel 1 also reduce the risk of equipment failure and damage, ensuring the continuity and stability of textile production. In short, the single-sided and double-sided oiling high-precision guide wheel 1 of the two-for-one twisting machine of this solution has shown significant improvements in lubrication convenience, ease of operation, environmental protection and production efficiency, providing an efficient and economical solution for the textile industry.

[0078] Attached Figure 4 and attached Figure 5 In the figure, any of sub-figures (1) to (6) is a constituent element of the plan view on the left and the cross-sectional view on the right.

[0079] Embodiment 1: (combination Figure 5 As shown in sub-figure (2) in

[0080] In this solution, two second grooves 2b3 are penetrated, and two second short nails 2b5 are threadedly fitted at both ends to seal the two ends. Two second side holes 2b8 are provided, and plugs 2b9 are provided in the second side holes 2b8. The second grooves 2b3 are connected with a plurality of second oil outlets 2b4. Therefore, the lubricating oil can be added by removing any of the second short nails 2b5 at the two ends. Alternatively, the two second short nails 2b5 are not removed, and the plugs 2b9 at the two second side holes 2b8 are removed, so that the lubricating oil can be added through any of the second side holes 2b8 at the two ends, thereby realizing the selective addition of the lubricating oil at the two ends. The operation is highly flexible and easy to use, and the filling can be performed on both the ends and the sides.

[0081] Embodiment 2: (combination Figure 5 As shown in sub-figure (3) in

[0082] Compared with the embodiment, in this solution, the two second grooves 2b3 are still in a through-connected state, and the second grooves 2b3 are connected to a plurality of second oil outlets 2b4. The difference is that both ends of the second grooves 2b3 are threadedly fitted with two second long nails 2b6. When in use, any second long nail 2b6 can be removed to add lubricating oil to either end.

[0083] The main difference from Example 1 is the filling method that can be passed through both ends.

[0084] Example 3: (combined Figure 5 As shown in sub-figure (4) in

[0085] Compared with Examples 1 and 2, this solution adopts a design of a second groove 2b3, and two second side holes 2b8 are opened on the surface of the bidirectional shaft 2b body. A second groove 2b3 of this solution can be opened at any end of the bidirectional shaft 2b body, and is used to connect the two second side holes 2b8 with a plurality of second oil outlets 2b4, wherein one end of the second groove 2b3 is provided with a second head 2b7 which is different from that of Examples 1 and 2, and the second head 2b7 keeps the second groove 2b3 sealed. At the same time, the two second side holes 2b8 are both provided with blocked second side holes 2b8. When in use, any plug 2b9 can be removed to realize the filling of lubricating oil into the second side holes 2b8 at both ends.

[0086] The difference from the first embodiment is that lubricating oil can only be added by using the second side holes 2b8 at both ends.

[0087] Embodiment 4: (combination Figure 5 As shown in sub-figure (5) in

[0088] It is basically the same as the embodiment 3, and the distinguishing feature is that only the second side hole 2b8 at one end is retained, and the second side hole 2b8 does not need to be sealed by the plug 2b9.

[0089] Example 5: (Combined Figure 5 As shown in sub-figure (6) in

[0090] This solution opens a second groove 2b3 at one end of the bidirectional shaft 2b body, and the position of the second groove 2b3 is sealed by a second long nail 2b6 and connected to a plurality of second oil outlets 2b4. Lubricating oil can be added by removing the second long nail 2b6. At the same time, a second side hole 2b8 is provided at the other end of the bidirectional shaft 2b body, and lubricating oil can be added through the second side hole 2b8 at the other end of the bidirectional shaft 2b body, thereby realizing bidirectional and different methods of lubricating oil filling.

[0091] The above-mentioned embodiments 1 to 5 are only several relatively significant and representative implementation methods. Further, there are also variations and applications of the second long nail 2b6 and the second short nail 2b5. For example, in embodiment 5, the second long nail 2b6 is replaced by the second short nail 2b5 or the second head 2b7.

[0092] Or for example, in Embodiment 2, a second long nail 2b6 is used at one end and a second short nail 2b5 is used at the other end, and a second side hole 2b8 can be provided at the position of the second short nail 2b5.

[0093] Comparative Example 1: (combined Figure 5 As shown in sub-figure (1) in

[0094] In this solution, grooves are provided at both ends of the axle 2, and screws can be fitted into the grooves. This solution does not have a design for adding lubricating oil, but is relatively simple to manufacture and has a lower cost.

[0095] Example 6: (Combined Figure 4 As shown in sub-figure (2) in

[0096] This scheme is a unidirectional design. In the two-for-one twisting machine, it is necessary to use a unidirectional mounting support guide wheel 1 in some cases. It is extended by the first groove 2a3 opened at one end of the unidirectional shaft 2a body to make it connected with several first oil outlets 2a4. At the same time, the inner wall of the first groove 2a3 is fixed with the first long nail 2a5 by threading. When lubricating oil needs to be added, it only needs to remove the first long nail 2a5 to add lubricating oil to the first groove 2a3.

[0097] Example 7: (Combined Figure 4 As shown in sub-figure (3) in

[0098] This solution is basically the same as Example 6, and the difference lies in that the first short nail 2a6 is used to replace the first long nail 2a5, which can be disassembled faster and facilitate more frequent oiling needs, but cannot meet the installation needs of higher strength.

[0099] Embodiment 8: (combination Figure 4 As shown in sub-figure (4) in

[0100] The difference between this solution and Examples 6 and 7 is that one end of the first groove 2a3 is sealed by a first head 2a7. When in use, the first head 2a7 cannot be removed, and a first side hole 2a8 is provided on the side wall of the one-way shaft 2a body. When in use, this solution can directly add lubricating oil through the first side hole 2a8, and in this solution, the inner wall of the first side hole 2a8 does not need to be sealed by a plug 2b9.

[0101] Example 9: (Combined Figure 4 As shown in sub-figure (5) in

[0102] The difference between this scheme and Example 2 is that a first side hole 2a8 is added, so that in addition to adding lubricating oil through the first side hole 2a8 on the side, lubricating oil can also be added by removing the first short nail 2a6. In this scheme, the first side hole 2a8 needs to be blocked by a plug 2b9 (not shown in the figure).

[0103] Example 10: (Combined Figure 4 As shown in sub-figure (6) in

[0104] This scheme is a relatively special implementation method. The opening of the first groove 2a3 of the one-way shaft 2a body is not blocked. When in use, it is necessary to use either the first short nail 2a6 or the first head 2a7 for blocking. The more significant difference is that the first side hole 2a8 is not opened on one side of the one-way shaft 2a body, but an extension interface 2a9 is directly installed. This interface can realize the connection of pipelines, including but not limited to hoses. The automatic dripping equipment of lubricating oil can be connected through the pipeline. For some high-load guide wheels 1, the management frequency of personnel can be reduced, and the high-load guide wheel 1 and the low-load guide wheel 1 can be processed simultaneously and uniformly over a period of time.

[0105] In this embodiment, the implementation scheme of providing lubricating oil through intelligent or automatic addition is further satisfied.

[0106] Comparative Example 2: (combined Figure 4 As shown in sub-figure (1) in

[0107] This structure is a standard one-way shaft 2a, which is provided with a first groove 2a3, and can meet the need of installation by screws, but is difficult to meet the need of rapid addition of lubricating oil.

[0108] In the above, the first long nail 2a5 is compared with the first short nail 2a6, and the second long nail 2b6 is compared with the second short nail 2b5. The difference is that the first short nail 2a6 and the second short nail 2b5 are only used for sealing the end of the first groove 2a3 or the second groove 2b3, and the first long nail 2a5 and the second long nail 2b6, in contrast, can be matched with more thread turns on the inner wall, have higher mechanical strength, and can be installed with other components when needed. It should be noted that the first long nail 2a5 and the second long nail 2b6 will cause the first side hole 2a8 and the second side hole 2b8 to be blocked, so the first side hole 2a8 and the second side hole need to be matched with the application of the first short nail 2a6 and the second short nail 2b5.

[0109] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
