Description

Technical Field

[0001] This utility model belongs to the field of textile machinery, specifically relating to a double roller seat device in the drafting transmission system of a ring spinning machine. Background Technology

[0002] Traditional ring spinning frames use a split roller mount system, with the left and right roller mounts being mirror images of each other. In recent years, due to various factors, more and more users have been increasing the number of spindles and adopting high-quantity, high-draft processes. Users frequently report deformation and movement on the left side of the middle and rear roller slides and drive shaft mounted on the left roller mount, and on the right side of the middle and rear roller slides and drive shaft mounted on the right roller mount. Furthermore, both left and right roller mounts exhibit longitudinal movement simultaneously, making these parts highly susceptible to damage, requiring machine downtime for maintenance, resulting in additional costs and production losses. Utility Model Content

[0003] In view of this, this utility model proposes a double roller seat device in the drafting and power transmission system of a ring spinning machine to solve the shortcomings of existing parts being easily damaged, requiring machine shutdown for maintenance, resulting in certain additional consumption and production loss.

[0004] In order to achieve the above-mentioned objectives of this utility model, the present utility model adopts the following technical solution:

[0005] A double roller seat device in the drafting transmission system of a ring spinning machine includes an integrally formed left roller assembly, a connecting assembly, and a right roller assembly. The connecting assembly connects the left roller assembly and the right roller assembly to form an integral double structure.

[0006] The left roller assembly is disposed at one end of the connecting assembly. The left roller assembly includes a roller seat, which includes a long roller seat and a short roller seat. Both the long roller seat and the short roller seat are provided with grooves. The long roller seat and the short roller seat are connected by a fixing plate. Both the long roller seat and the short roller seat are fixedly connected to a bracket by a first roller reinforcing rib and a second roller reinforcing rib. A support base is connected to the bottom end of the long roller seat and the bracket. Multiple mounting holes are evenly provided on the support base.

[0007] The right roller assembly is located at the other end of the connecting assembly, and the right roller assembly has the same structure as the left roller assembly. The right roller assembly and the left roller assembly are symmetrically arranged at both ends of the connecting assembly.

[0008] The connecting components include irregularly shaped connecting ribs and connecting ribs, which connect the left roller assembly and the right roller assembly.

[0009] Furthermore, the included angle between the bracket and the support base is 45°.

[0010] The irregularly shaped connecting rib in the connecting assembly connects the long side roller seat at both ends, and the connecting rib connects the bracket at both ends, forming a clearance space.

[0011] Furthermore, the irregularly shaped connecting rib has a machining hole in the middle and a wire mounting hole on it.

[0012] The long side roller seat body is provided with two long side roller seat sliding holes, and the short side roller seat body is provided with one short side roller seat sliding hole. Both the long side roller seat sliding hole and the short side roller seat sliding hole are provided with sliders.

[0013] Furthermore, the sliding holes on the long side roller seat are of different sizes, with the larger sliding hole being a movable sliding hole and the smaller sliding hole being a fixed sliding hole.

[0014] The beneficial effects of this utility model are as follows: The key components of the drafting transmission system of the ring spinning machine, the left and right roller seats, are connected as one unit. The roller seats of the left and right roller assemblies are strengthened by the special-shaped connecting ribs and reinforcing ribs, thus enhancing the overall structural rigidity. The lateral deformation of the roller seats of the left and right roller assemblies is eliminated, fundamentally eliminating the lateral and longitudinal movement of the roller seats during operation. Ultimately, this improves the operating condition of the middle and rear roller slides and the middle and rear roller heads and their bearings installed on them, significantly extending the service life of these parts, stabilizing yarn quality, and reducing additional losses and production losses for users.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0024] Traditional ring spinning frames use a split roller mount system with left and right roller mounts, structurally mirror-symmetrical. In recent years, operational experience has revealed deformation and movement on the left side of the middle and rear roller slides and drive shaft mounted on the left roller mount, and on the right side of the middle and rear roller slides and drive shaft mounted on the right roller mount. Furthermore, both left and right roller mounts exhibit longitudinal movement simultaneously, making these components highly susceptible to damage, requiring machine downtime for maintenance, resulting in additional costs and production losses. Theoretical analysis, calculations, and actual monitoring have revealed that this is due to the original split roller mount's structural inability to withstand the large loads required by current spinning processes. Therefore, structural design improvements are needed to enhance the roller mount's rigidity and load-bearing capacity, ensuring reliable and stable operation of the mounted components, consistent yarn quality, and compliance with actual spinning process requirements.

[0025] The solution provided by this utility model will now be described in detail with reference to the accompanying drawings.

[0026] like Figure 1-5 As shown, a double roller seat device in the drafting transmission system of a ring spinning machine includes an integrally formed left roller assembly 1, a right roller assembly 2, and a connecting assembly 3. The left roller assembly 1 and the right roller assembly 2 have a left-right mirror symmetrical structure, and the connecting assembly 3 connects the left roller assembly 1 and the right roller assembly 2 to form an integral double structure.

[0027] like Figure 1 As shown, the left roller assembly 1 is disposed at one end of the connecting assembly 2. The left roller assembly 1 includes a roller seat 101, which includes a long side roller seat 101-1 and a short side roller seat 101-2. Both the long side roller seat 101-1 and the short side roller seat 101-2 are provided with grooves 102. The long side roller seat 101-1 and the short side roller seat 101-2 are connected by a fixing plate 103. Both the long side roller seat 101-1 and the short side roller seat 101-2 are fixedly connected to a bracket 106 by a first roller reinforcing rib 104 and a second roller reinforcing rib 105. A support seat 107 is connected to the bottom end of the long side roller seat 101-1 and the support seat 106. The support seat 107 is provided with a plurality of mounting holes 108 evenly distributed on it.

[0028] The right roller assembly 2 is located at the other end of the connecting assembly 3, and the right roller assembly 2 has the same structure as the left roller assembly 1. The right roller assembly 2 and the left roller assembly 1 are symmetrically arranged at both ends of the connecting assembly 3.

[0029] The connecting component 3 includes a shaped connecting rib 301 and a connecting rib 302, which connect the left roller assembly 1 and the right roller assembly 2.

[0030] Based on the above embodiments, the included angle between the bracket 106 and the support base 107 is 45°, and the 45° included angle can improve the stability of the roller seat.

[0031] The irregular connecting rib 301 in the connecting component 3 connects to the long side roller seat 101-1 at both ends, and the connecting rib 302 connects to the bracket 106 at both ends, forming a clearance space.

[0032] The clearance space is formed because the height of the long side roller seat 101-1 is higher than the height of the support 106. After the irregular connecting ribs 301 and 302 are connected to the long side roller seat 101-1 and the support seat 107 at both ends, a clearance space is formed between the irregular connecting ribs 301 and 302 to accommodate the components on the spinning machine.

[0033] The irregular connecting rib 301 has a machining process hole 303 in the middle and a wire mounting hole 304 on the irregular connecting rib 301.

[0034] like Figure 2-5 As shown, the long side roller seat 101-1 is provided with two long side roller seat sliding holes 4, and the short side roller seat 101-2 is provided with one short side roller seat sliding hole 5. Both the long side roller seat sliding hole 4 and the short side roller seat sliding hole 5 are provided with sliders 6.

[0035] Among them, the sliding holes 4 of the long side roller seat are of different sizes, the larger sliding hole is a movable sliding hole 401, and the smaller sliding hole is a fixed sliding hole 402.

[0036] Based on the above embodiments, the slide holes 4 and 5 of the long side roller seat ensure that the sliders 6 on the roller seat 101 can be installed in a staggered manner. Three sliders 6 are installed on the roller seat 101 through the movable slide hole 401, the fixed slide hole 402 and the slide hole 5 of the short side roller seat. The front roller, the middle roller and the rear roller are respectively arranged inside the three sliders 6. The installation positions of the middle roller and the rear roller are adjusted by moving the sliders 6 in the groove 102.

[0037] Specifically, before use, the double roller seat device needs to be installed at the head, middle, or tail of the ring spinning machine according to requirements. After positioning with tools, the double roller seat is fixed to the ring spinning machine with bolts through the mounting holes 108. Finally, the remaining parts are installed on it. During the operation of the ring spinning machine, since the left roller assembly 1 and the right roller assembly 2 are connected by the connecting assembly 3 to form a whole, the double roller seat is prevented from moving during operation, which improves the operating condition of the roller slide, roller head section, and bearings installed on it.

[0038] The above are merely embodiments of this application and do not limit the patent scope of this application. Any equivalent structural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
