Description

Technical Field

[0001] This utility model relates to the technical field of spinning preparation devices, and in particular to a top comb clamping device for a flax combing machine. Background Technology

[0002] The combing machine is an important piece of equipment in the textile industry, used to straighten and align fibers for the next spinning process. The top comb, as a crucial component of the combing machine, primarily functions to comb the rear end of the fiber bundle, removing short fibers, neps, and impurities trapped within, and improving fiber straightness and parallelism. The top comb is mounted on the lower nipper plate via a bracket and swings with the nipper plate. During the combing process, the top comb is positioned between the nipper plate and the separating roller, used to insert into the fiber bundle during the separation and joining of old and new fiber bundles, combing the rear end of the fiber bundle.

[0003] Most existing top combs are fixed to the mounting frame inside the combing machine with bolts. Although this fixing method is stable and reliable, the installation and disassembly process is cumbersome and time-consuming in the confined space.

[0004] Therefore, in view of the above situation, there is an urgent need to develop a top comb clamping device for flax combing machines to overcome the shortcomings in current practical applications. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a top comb clamping device for a flax combing machine, which aims to solve the problems mentioned in the background art.

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

[0007] A top comb clamping device for a flax combing machine includes a base plate, a placement plate fixedly connected to the upper end of the base plate, a placement groove formed on the placement plate, a receiving plate placed in the placement groove, a receiving groove formed on the receiving plate, a top comb fixedly connected in the receiving groove, two symmetrically distributed support plates fixedly connected to one side of the upper end of the base plate, a pressure plate rotatably connected between the two support plates, a transverse clamping assembly fitted at the lower end of the pressure plate, the transverse clamping assembly used to restrict the receiving plate from sliding along the inner wall of the placement groove, and two limiting components symmetrically distributed about the placement plate also fitted at the upper end of the base plate, the limiting components and the pressure plate cooperate to restrict the receiving plate from moving in a direction perpendicular to the placement groove.

[0008] In a further technical solution, the base plate and the placement plate are an integral structure.

[0009] In a further technical solution, a second chamfer is provided on both sides of the placement groove.

[0010] A further technical solution is provided, wherein the transverse clamping assembly includes a clamping groove, a first clamping plate and a guide plate; the clamping groove is provided at the bottom of the placement groove, and two symmetrically distributed first clamping plates are fixedly connected to the lower end of the pressure plate, and the distance between the two first clamping plates is equal to the width of the top comb; the other end of each first clamping plate is fixedly connected to a guide plate, and the angle between the guide plate and the first clamping plate is an obtuse angle.

[0011] In a further technical solution, the first clamping plate and the guide plate are integrally formed.

[0012] A further technical solution includes a first forming plate, a second forming plate, a limiting slider, a gantry frame, a first rotating plate, and a deflector plate; the upper end of the base plate is fixedly connected to the first forming plate and the second forming plate, the inner walls of the first forming plate and the second forming plate are slidably connected to the same limiting slider, the limiting slider is rotatably connected to the gantry frame, the gantry frame is fixedly connected to the deflector plate, and the gantry frame and the first forming plate are rotatably connected to the first forming plate.

[0013] A further technical solution is to provide a first chamfer at the end of the first chamfer closest to the pressure plate.

[0014] In summary, the embodiments of this utility model have the following beneficial effects compared with the prior art:

[0015] By placing the receiving plate for installing the top comb into the placement groove, and then controlling the pressure plate to rotate and descend until the pressure plate abuts against the upper end of the receiving plate, the two first clamping plates abut against the side wall of the receiving plate, thereby restricting the receiving plate from sliding along the inner wall of the placement groove. The lever is then moved away from the pressure plate, and the lever drives the gantry frame to rotate. Under the action of the first rotating plate, the gantry frame drives the limiting slider to slide along the inner wall of the second and first round plates towards the pressure plate during rotation, until the limiting slider abuts against the pressure plate at one end, thereby fixing the pressure plate and restricting the receiving plate from moving in a direction perpendicular to the placement groove. This fixes the receiving plate from multiple directions, thereby fixing the top comb. The operation is simple and quick.

[0016] By using an obtuse angle between the guide plate and the first clamping plate, the receiving plate is adjusted to the middle position of the placement groove by the two guide plates, and then the two first clamping plates restrict the receiving plate from sliding along the inner wall of the placement groove, thus allowing a certain deviation when placing it on the inner wall of the placement groove, which helps to quickly install the receiving plate with the top comb.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] like Figures 1-5 As shown, this utility model embodiment provides a top comb clamping device for a flax combing machine, including a base plate 1, which is fixedly installed on a mounting frame inside the combing machine. A placement plate 2 is fixedly connected to the upper end of the base plate 1. A placement groove 3 is provided on the placement plate 2, and a receiving plate 5 is placed in the placement groove 3. A receiving groove 6 is provided on the receiving plate 5, and a top comb 7 is fixedly connected in the receiving groove 6. Two symmetrically distributed support plates 8 are fixedly connected to one side of the upper end of the base plate 1. A pressure plate 9 is rotatably connected between the two support plates 8. A transverse clamping component 4 is provided at the lower end of the pressure plate 9. The transverse clamping component 4 is used to restrict the receiving plate 5 from sliding along the inner wall of the placement groove 3. Two limiting components 10 are also provided at the upper end of the base plate 1, which are symmetrically distributed about the placement plate 2. The limiting components 10 and the pressure plate 9 cooperate to restrict the movement of the receiving plate 5 in a direction perpendicular to the placement groove 3.

[0027] Furthermore, the base plate 1 and the placement plate 2 are an integral structure.

[0028] Furthermore, a second chamfer (not shown in the figure) is provided on both sides of the placement groove 3, which facilitates the placement of the receiving plate 5 in the placement groove 3.

[0029] It can be understood that the structure of a top comb typically includes a base plate on which multiple rows of comb needles are fixed, arranged in an array.

[0030] like Figure 3 and Figure 4 As shown, the transverse clamping assembly 4 includes a clamping groove 41, a first clamping plate 42, and a guide plate 43; the bottom end of the placement groove 3 is provided with a clamping groove 41, and the lower end of the pressure plate 9 is fixedly connected to two symmetrically distributed first clamping plates 42, and the distance between the two first clamping plates 42 is equal to the width of the top comb 7. The other end of each first clamping plate 42 is fixedly connected to a guide plate 43, and the included angle between the guide plate 43 and the first clamping plate 42 is an obtuse angle.

[0031] Furthermore, the first clamping plate 42 and the guide plate 43 are integrally formed structures.

[0032] In practical application, the receiving plate 5 with the top comb 7 installed is placed into the placement groove 3, and then the pressure plate 9 is controlled to rotate and descend until the pressure plate 9 abuts the upper end of the receiving plate 5. During this process, as the first clamping plate 42 and the guide plate 43 descend, the receiving plate 5 is adjusted to the middle position of the placement groove 3 by the two guide plates 43. As the pressure plate 9 continues to rotate and descend, the first clamping plate 42 contacts the side wall of the receiving plate 5, thereby restricting the receiving plate 5 from sliding along the inner wall of the placement groove 3.

[0033] like Figure 1 and Figure 2 As shown, the limiting assembly 10 includes a first forming plate 101, a second forming plate 102, a limiting slider 103, a portal frame 104, a first rotating plate 105, and a lever plate 106; the first forming plate 101 and the second forming plate 102 are fixedly connected to the upper end of the base plate 1, the same limiting slider 103 is slidably connected to the inner walls of the first forming plate 101 and the second forming plate 102, the portal frame 104 is rotatably connected to the limiting slider 103, the lever plate 106 is fixedly connected to the portal frame 104, and the first rotating plate 105 is rotatably connected between the portal frame 104 and the first forming plate 101.

[0034] Furthermore, the first chamfer 107 is provided at one end near the pressure plate 9.

[0035] In practical application, when the pressure plate 9 abuts against the upper end of the receiving plate 5, the lever 106 is moved away from the pressure plate 9. Then the lever 106 drives the gantry frame 104 to rotate. Then, under the action of the first rotating plate 105, the gantry frame 104 drives the limiting slider 103 to slide along the inner wall of the second forming plate 102 and the first forming plate 101 towards the pressure plate 9 until the limiting slider 103 abuts against the pressure plate 9 at one end of its lower side, thereby fixing the pressure plate 9.

[0036] In this embodiment of the utility model, by placing the receiving plate 5 with the top comb 7 installed into the placement groove 3, and then controlling the pressure plate 9 to rotate and descend until the pressure plate 9 abuts against the upper end of the receiving plate 5, the two first clamping plates 42 abut against the side wall of the receiving plate 5, thereby restricting the receiving plate 5 from sliding along the inner wall of the placement groove 3. The lever 106 is then moved away from the pressure plate 9, and the lever 106 drives the gantry frame 104 to rotate. Then, under the action of the first rotating plate 105, the gantry frame 104 drives the limiting slider 103 to slide along the inner wall of the second back-shaped plate 102 and the first back-shaped plate 101 towards the pressure plate 9 during the rotation. The limiting slider 103 abuts against the pressure plate 9 near one end, thereby fixing the pressure plate 9 and restricting the movement of the receiving plate 5 in a direction perpendicular to the placement groove 3. This fixes the receiving plate 5 from multiple directions and thus fixes the top comb 7. The operation is simple and quick. The angle between the guide plate 43 and the first clamping plate 42 is an obtuse angle. The two guide plates 43 adjust the receiving plate 5 to the middle position of the placement groove 3. Then, the two first clamping plates 42 restrict the receiving plate 5 from sliding along the inner wall of the placement groove 3. This allows for a certain deviation when placing it on the inner wall of the placement groove 3, which helps to quickly install the receiving plate 5 with the top comb 7.

[0037] The working principle of this utility model is as follows: First, the top comb 7 is fixedly installed in the receiving groove 6 outside the combing machine, thereby fixing the receiving plate 5 and the top comb 7 together. Then, the pressure plate 9 is controlled to rotate and descend until the pressure plate 9 abuts against the upper end of the receiving plate 5. During this process, as the first clamping plate 42 and the guide plate 43 descend, the two guide plates 43 first adjust the receiving plate 5 to the middle position of the placement groove 3. As the pressure plate 9 continues to rotate and descend, the first clamping plate 42 contacts the side wall of the receiving plate 5, thereby restricting the receiving plate 5 from sliding along the inner wall of the placement groove 3. Then, the lever 106 is moved away from the pressure plate 9. The lever 106 then drives the gantry frame 104 to rotate. Then, under the action of the first rotating plate 105, the gantry frame 104 drives the limiting slider 103 to slide along the inner wall of the second forming plate 102 and the first forming plate 101 towards the pressure plate 9 until the limiting slider 103 abuts against the pressure plate 9 at one end, thereby fixing the pressure plate 9. Then, the pressure plate 9 restricts the receiving plate 5 from moving in a direction perpendicular to the placement groove 3, thereby fixing the receiving plate 5 from multiple directions.

[0038] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
