Description

Technical Field

[0001] This utility model specifically relates to the field of leaf spring cradle technology, and more specifically to an adjustable leaf spring cradle. Background Technology

[0002] A leaf spring cradle is a key component used in textile machinery, especially in spinning machines. It is mainly used to pressurize and position components such as rollers and rubber rollers to achieve effective control and drafting of fibers, thereby ensuring yarn quality. Its working principle is based on the deformation characteristics of the elastic element (leaf spring). Through a mechanical structure, the elastic force of the leaf spring is converted into stable pressure on the fiber drafting area, ensuring effective control of fibers during the spinning process.

[0003] During use, depending on the different spinning processes, it is necessary to adjust the pressure between the roller and the rubber roller, as well as the position between the roller and the rubber roller, at any time to improve yarn quality and reduce energy consumption and equipment wear.

[0004] However, in practice, it has been noted that most pressure regulating mechanisms are currently fixed to the cradle body using bolts, relying on friction at the connection point. Moreover, since the cradle body is mostly tilted on the spinning machine, the reaction force of the leaf spring is applied to the leaf spring cradle. Prolonged stress can cause a slight shift in the position between the leaf spring cradle and the cradle body, thus affecting the process quality of the leaf spring cradle during operation. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable leaf spring rocker arm. The position of the internally threaded cylinder can be adjusted through the threaded engagement between the internally threaded cylinder and the fixed threaded rod. Furthermore, the position of the pressure regulator at the end of the hollow outer shell can be adjusted via the side slide plate and the perforated upright plate. The self-locking characteristic of the thread prevents the pressure regulator from shifting during use, thus improving stability. This addresses the technical problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An adjustable leaf spring rocker arm includes a rocker arm housing, with a locking handle movably connected to the top of the rocker arm housing;

[0008] The cradle housing includes a hollow housing, one end of which has a rectangular array of limit grooves, and the other end of the hollow housing is also equipped with a rectangular array of pressure regulators corresponding to the limit grooves.

[0010] As a further technical solution of this utility model, the pressure regulator includes a mounting base, with side slide plates fixedly connected to both sides of the mounting base. The side slide plate away from the mounting base is integrally provided with a perforated upright plate, which extends through the limiting slide groove to the outside of the hollow shell.

[0011] As a further technical solution of this utility model, the hole plate is rotatably fitted with an internally threaded cylinder, the internally threaded cylinder is sleeved on the outside of the fixed threaded rod, and the fixed threaded rod and the internally threaded cylinder are threadedly engaged, the fixed threaded rod is specifically a triangular threaded rod.

[0012] As a further technical solution of this utility model, the inner side of the mounting base is engaged with a pressure leaf spring, and the other end of the pressure leaf spring is inclined downward, and the end of the pressure leaf spring away from the mounting base is fixedly connected to a yarn guide holder.

[0013] As a further technical solution of this utility model, the pressure leaf spring is located on the inner side of the mounting base in a U-shape. The top of the mounting base is also threaded with a pressure adjusting screw, and the bottom of the pressure adjusting screw is in contact with the end of the pressure leaf spring. The top of the pressure adjusting screw extends through the limiting groove to the top of the hollow shell.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model adjusts the position of the mounting base inside the hollow shell by means of the threaded engagement between the internal threaded rotating cylinder and the fixed threaded rod. Furthermore, the self-locking characteristic of the threaded connection prevents the pressure regulator from sliding inside the hollow shell after being subjected to force for a long time. This makes it convenient for workers to adjust the position of the yarn guide on the leaf spring rocker and also prevents the adjusted yarn guide from shifting during use, thereby improving the stability after adjustment.

[0016] This utility model uses a perforated vertical plate to movably connect an internally threaded rotating cylinder to the side of a side slide plate, ensuring that the internally threaded rotating cylinder can rotate on the side of the mounting base.

Detailed Implementation

[0025] 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.

[0026] Please see Figure 1-5 This utility model embodiment provides an adjustable leaf spring rocker, including a rocker housing 2, and a locking rocker handle 1 movably connected to the top of the rocker housing 2;

[0027] The cradle housing 2 includes a hollow housing 21. One end of the hollow housing 21 has a rectangular array of limit grooves 22, and the end of the hollow housing 21 is also equipped with a pressure regulator 5 corresponding to the limit grooves 22 in a rectangular array.

[0028] Furthermore, symmetrical end fixing plates 23 are fixedly connected to both sides of the hollow outer shell 21, and a fixing threaded rod 24 is fixedly connected between the two end fixing plates 23, and the fixing threaded rod 24 is located on the side of the limiting slide groove 22.

[0029] Furthermore, the pressure regulator 5 includes a mounting base 51, with side slide plates 55 fixedly connected to both sides of the mounting base 51. The side slide plate 55 away from the mounting base 51 is integrally provided with a perforated upright plate 56, and the perforated upright plate 56 extends through the limiting slide groove 22 to the outside of the hollow shell 21.

[0030] By adopting the above technical solution, the position of the mounting base 51 inside the hollow shell 21 is adjusted through the threaded engagement between the internal threaded rotating cylinder 57 and the fixed threaded rod 24. Furthermore, the self-locking characteristic of the threaded connection can prevent the pressure regulator 5 from sliding inside the hollow shell 21 after being subjected to force for a long time. This facilitates the adjustment of the yarn guide's position on the leaf spring cradle and prevents the adjusted yarn guide from shifting during use, thereby improving the stability after adjustment.

[0031] More specifically, the perforated plate 56 is rotatably fitted with an internally threaded cylinder 57, which is sleeved on the outside of the fixed threaded rod 24, and the fixed threaded rod 24 and the internally threaded cylinder 57 are threadedly engaged. The fixed threaded rod 24 is specifically a triangular threaded rod.

[0032] Furthermore, a pressure leaf spring 52 is engaged with the inner side of the mounting base 51, and the other end of the pressure leaf spring 52 is inclined downward, and a yarn guide holder 54 is fixedly connected to the end of the pressure leaf spring 52 away from the mounting base 51.

[0033] Furthermore, the pressure leaf spring 52 is located inside the mounting base 51 in a U-shape. The top of the mounting base 51 is also threaded with a pressure adjusting screw 53, and the bottom of the pressure adjusting screw 53 is in contact with the end of the pressure leaf spring 52. The top of the pressure adjusting screw 53 extends through the limiting groove 22 to the top of the hollow shell 21.

[0034] By adopting the above technical solution, the internal threaded cylinder 57 is movably connected to the side of the side slide plate 55 through the perforated plate 56, and it is ensured that the internal threaded cylinder 57 can rotate on the side of the mounting base 51. Moreover, when the internal threaded cylinder 57 rotates outside the fixed threaded rod 24, the pressure regulator 5 is adjusted through the mutual cooperation between the internal threaded cylinder 57 and the fixed threaded rod 24.

[0035] Furthermore, the lengths of the multiple limiting slide grooves 22 decrease sequentially from left to right. The hollow outer shell 21 has a through slide groove 6 at one end away from the limiting slide groove 22, and one end of the locking handle 1 extends through the through slide groove 6 to the inner side of the hollow outer shell 21, while the other end of the locking handle 1 is fixedly connected to a pressing handle 4.

[0036] Furthermore, the hollow outer shell 21 is provided with a mounting hole 7 at its end, and the mounting hole 7 is located below the through groove 6, and the shaft locking device 3 is symmetrically arranged on both sides inside the mounting hole 7.

[0037] The working principle of this utility model is as follows: First, the spring rocker arm is installed on the spinning machine, and the fixed rod on the spinning machine passes through the through groove 6 on the hollow outer shell 21. The shaft locking device 3 is pressed using the pressing handle 4, which fixes the rocker arm shell 2 to the outside of the fixed rod. Then, the internal threaded drum 57 is rotated. The internal threaded drum 57 rotates outside the fixed threaded rod 24. Through the threaded engagement between the internal threaded drum 57 and the fixed threaded rod 24, the internal threaded drum 57 slides left and right on the fixed threaded rod 24. The internal threaded drum 57, through the externally provided perforated plate 56, drives the mounting seat 51 to slide inside the hollow outer shell 21, thereby adjusting the position of the mounting seat 51 inside the hollow outer shell 21. Furthermore, the self-locking characteristic of the triangular thread prevents the mounting seat 51 from shifting during prolonged use. The structure is simple, the operation is very convenient, and it effectively reduces manual labor intensity.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
