Description

Technical Field

[0001] This utility model relates to the field of warp knitting machine technology, and in particular to a rotating roller intermediate connecting unit. Background Technology

[0002] When the rotating rollers on a warp knitting machine exceed a certain length, intermediate supports need to be added to ensure the rigidity of the rollers.

[0003] The structure used in the intermediate connecting unit of the rotating roller on the warp knitting machine is that the intermediate support 105 is equipped with a bearing and an intermediate shaft 200 is installed inside. The rotation of the left roller 101 and the right roller 102 is driven by the shaft key 201 on the intermediate shaft 200.

[0004] However, the above-mentioned rotating roller intermediate connection unit structure has the problem that the intermediate shaft 200 is not strong enough when the roller diameter is less than 70mm, which makes the intermediate shaft 200 easy to be damaged and difficult to meet the use requirements; therefore, a rotating roller intermediate connection unit is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a rotating roller intermediate connecting unit to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rotating roller intermediate connecting unit, comprising:

[0007] An intermediate support member, wherein a rotating connector is fixedly provided on the inner side of the intermediate support member;

[0008] A left rotating roller is located on one side of the intermediate support member and is rotatably connected to the intermediate support member via a rotating connector.

[0009] A right rotating roller is located on the other side of the intermediate support and is rotatably connected to the intermediate support via a rotating connector.

[0010] The transmission shaft has two ends that movably pass through both sides of the intermediate support member and are fixedly installed inside the left and right rotating rollers.

[0011] Preferably, the rotating connector includes:

[0012] The second bushing has its outer wall center fixedly connected to the inner side of the intermediate support member.

[0013] Two first bushings are respectively fixedly connected to the inner walls of the left rotating roller and the right rotating roller;

[0014] Two needle roller bearings are fixedly connected between the inner ends of the two first bushings and the two ends of the outer wall of the second bushing.

[0015] Preferably, limit components are provided at both ends of the drive shaft and between the left and right rotating rollers, and the limit components are used to limit and fix the drive shaft to the left and right rotating rollers in the radial direction.

[0016] Preferably, the limiting component includes a keyway and a key block that are adapted to each other. The keyway is formed on the inner wall of the first bushing, and the key block is fixedly connected to the end of the outer wall of the transmission shaft.

[0017] Preferably, the second bushing has a through groove in the middle that matches the drive shaft and the key block, and the size of the through groove is larger than the size of the drive shaft and the key block.

[0018] Preferably, a support member clamping screw is fixedly provided between the intermediate support member and the second bushing, and bushing clamping screws are fixedly connected between the two first bushings and the corresponding left and right rotating rollers.

[0019] Compared with the prior art, the technical effects of this utility model are as follows:

[0020] This invention enables the left and right rotating rollers to be fixed on both sides of the intermediate support while allowing them to rotate independently. Furthermore, a drive shaft is movably inserted into the center of the intermediate support to synchronously limit the radial movement of the left and right rotating rollers. This allows the drive shaft to drive the left and right rotating rollers to rotate synchronously in the same direction, reducing the load on the drive shaft and making it suitable for connections with smaller roller diameters, thus improving its adaptability.

Detailed Implementation

[0024] 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.

[0025] like Figure 2 As shown, in the prior art, the intermediate connecting unit of the rotating roller consists of an internally connected bearing in the intermediate support 105, which connects to the intermediate shaft 200. The left rotating roller 101 and the right rotating roller 102 are then engaged and limited by internally fixed bushings with the key 201 on the outer wall of the intermediate shaft 200. Although the intermediate shaft 200 can drive the left rotating roller 101 and the right rotating roller 102 to rotate, the load of the left rotating roller 101 and the right rotating roller 102 is concentrated on the intermediate shaft 200. This results in the intermediate shaft 200 diameter decreasing when the diameters of the left rotating roller 101 and the right rotating roller 102 are small, thus reducing the strength of the intermediate shaft 200 and making it prone to damage.

[0026] This utility model provides, for example Figure 1 The rotating roller intermediate connecting unit shown includes an intermediate support 105, a left rotating roller 101, a right rotating roller 102, and a drive shaft 100. A rotating connector is fixedly provided on the inner side of the intermediate support 105. The left rotating roller 101 is located on one side of the intermediate support 105 and is rotatably connected to the intermediate support 105 through the rotating connector. The right rotating roller 102 is located on the other side of the intermediate support 105 and is rotatably connected to the intermediate support 105 through the rotating connector. The two ends of the drive shaft 100 respectively movably pass through both sides of the intermediate support 105 and are fixedly provided on the inner side of the left rotating roller 101 and the right rotating roller 102. The left rotating roller 101 and the right rotating roller 102 are connected to the intermediate support 105 through rotating connectors, which can reduce the load on the drive shaft 100. Therefore, the strength requirements of the drive shaft 100 can be reduced, so that the drive shaft 100 requires less rigidity when driving the left rotating roller 101 and the right rotating roller 102 to rotate synchronously. Therefore, when the roller diameters of the left rotating roller 101 and the right rotating roller 102 are small (especially when they are 70mm), the drive shaft 100 can still stably drive the left rotating roller 101 and the right rotating roller 102 to rotate, reducing damage to the drive shaft 100 and extending its service life.

[0027] The rotating connector includes a second bushing 108, two first bushings 103, and two needle roller bearings 107. The middle of the outer wall of the second bushing 108 is fixedly connected to the inner side of the intermediate support 105. The two first bushings 103 are respectively fixedly connected to the inner walls of the left rotating roller 101 and the right rotating roller 102. The two needle roller bearings 107 are respectively fixedly connected between the inner ends of the two first bushings 103 and the two ends of the outer wall of the second bushing 108. The first bushings 103 are fixedly installed at the close ends of the inner walls of the left rotating roller 101 and the right rotating roller 102. Then, the needle roller bearings 107 are used to fix the second bushing 108, which is fixed to the inner side of the intermediate support 105, so that the intermediate support 105 can assist in connecting the left rotating roller 101. The roller 101 and the right rotating roller 102 can also allow the left rotating roller 101 and the right rotating roller 102 to rotate stably on both sides of the intermediate support 105. In this way, the drive shaft 100 does not need to bear the load of the left rotating roller 101 and the right rotating roller 102. The intermediate support 105 and the second bushing 108 are fixedly provided with support member clamping screws 106. The two first bushings 103 are fixedly connected to the corresponding left rotating roller 101 and right rotating roller 102 with bushing clamping screws 104. The setting of support member clamping screws 106 and bushing clamping screws 104 makes the disassembly and assembly of the first bushings 103 and the second bushings 108 more convenient, thereby facilitating the disassembly, assembly and maintenance of the first bushings 103 and the second bushings 108.

[0028] Furthermore, limit components are provided at both ends of the drive shaft 100 and between it and the left rotating roller 101 and the right rotating roller 102. These limit components are used to limit and fix the drive shaft 100 to the left rotating roller 101 and the right rotating roller 102 in the radial direction. Each limit component includes a keyway and a key block that are mutually adapted. The keyway is formed on the inner wall of the first bushing 103, and the key block is fixedly connected to the end of the outer wall of the drive shaft 100. A through groove matching the drive shaft 100 and the key block is formed in the middle of the second bushing 108. The size of the through groove is larger than the size of the drive shaft 100 and the key block. The two ends of the outer wall of the drive shaft 100... The end has an integrally formed key block. The keyway of the first bushing 103 cooperates with the key block to realize the radial positioning of the drive shaft 100 and the first bushing 103. In this way, the drive shaft 100 can stably drive the left rotating roller 101 and the right rotating roller 102 to rotate during the rotation. The second bushing 108 has a through hole inside that matches the drive shaft 100 and the key block. The size of the through hole should be slightly larger than the size of the drive shaft 100 and the key block (generally greater than 1 mm) to allow the drive shaft 100 to pass through the inside of the second bushing 108, thereby facilitating assembly.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
