Technical Field

[0001] The utility model relates to the technical field of warp knitting machines, in particular to a novel spring reset mechanism device for a warp knitting machine. Background Technique

[0002] Using one or several groups of parallel arranged yarns, feeding them into all working needles of the machine in the warp direction, and forming loops simultaneously to form a knitted fabric. This method is called warp knitting, and the fabric is called warp knitted fabric. The machine that completes this warp knitting is called a warp knitting machine. The core of a warp knitting machine is the loop forming movement, which is driven by the main shaft to drive multiple groups of complex crankshafts to complete a series of coordinated movements of sinker needles, guide bars, needle cores, and sinkers.

[0003] In the current existing technology, since the warp knitting machine is in a high-speed running state during use, and the fixed connection of its electronic lateral displacement mechanism device is a rigid connection, when the warp knitting machine is working, the connection part is extremely easy to break and become loose, resulting in various torque forces and needle punching phenomena, reducing the reliability of the electronic lateral displacement mechanism and making it inconvenient to use the warp knitting machine. Summary of the Invention

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a novel spring reset mechanism device for a warp knitting machine is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: A novel spring reset mechanism device for a warp knitting machine, including a connecting shaft, a stud is fixedly connected to the right end of the connecting shaft, a locking nut is threadedly connected to the outer surface of the stud, a pressure spring is arranged on the side surface of the locking nut, a rear end face bearing is arranged at one end of the pressure spring, the inner surface of the rear end face bearing is attached to the outer surface of the connecting shaft, the side surface of the rear end face bearing is movably connected to a nut seat, the inner surface of the nut seat is attached to the outer surface of the connecting shaft, a connecting sleeve is threadedly connected to the right end of the nut seat, and the connecting shaft, stud, locking nut, pressure spring, and rear end face bearing are all located inside the connecting sleeve.

[0006] A through hole is opened on the upper surface of the locking nut, a threaded connection hole is opened on the outer surface of the stud, a fixing screw is arranged inside the through hole, and the lower end of the fixing screw is threadedly connected to the inside of the threaded connection hole.

[0007] A clamping groove is opened on the inner surface of the nut seat, an oil-impregnated bearing is arranged inside the clamping groove, and the inner surface of the oil-impregnated bearing is attached to the outer surface of the connecting shaft.

[0008] The side surface of the nut seat is movably connected to a front end face bearing, and the inner surface of the front end face bearing is attached to the outer surface of the connecting shaft.

[0009] The left end of the connecting shaft is movably connected with a fixing pin, and a combed wire rope is arranged on the outer surface of the fixing pin.

[0010] The right end inside of the connecting sleeve is movably connected with a bolt, the outer surface of the bolt is threadedly connected with a fixing nut, and the side surface of the fixing nut is attached to the right end surface of the connecting sleeve.

[0011] The utility model has the following beneficial effects:

[0012] Compared with the prior art, for this new type of warp knitting machine spring reset mechanism device, through the connecting shaft, stud, locking nut, compression spring, rear end face bearing, nut seat and connecting sleeve, one end of the device is connected with a combed wire rope, and the other end is connected with a traversing mechanism through a bolt. During operation, the reciprocating movement of the traversing mechanism drives the connecting sleeve to move back and forth, pulling the nut seat to move, so that the compression spring is reciprocally compressed and restored under force, thereby eliminating the external force generated during the working process. Compared with the current existing technology, since the warp knitting machine is in a high-speed operation state during use, and the fixed connection of its electronic traversing mechanism device is a rigid connection, when the warp knitting machine is working, the connection part is extremely prone to breakage and loosening, resulting in various torque forces and needle punching and other phenomena, reducing the reliability of the electronic traversing mechanism and making it inconvenient to use the warp knitting machine. This new type of warp knitting machine spring reset mechanism device can, under the high-speed operation state of the warp knitting machine, not loosen or break, and not generate external torque forces, needle punching and other phenomena, solving the problem of poor reliability of the electronic traversing structure of the high-speed warp knitting machine.

[0023] Refer to Figures 1-8, A novel warp knitting machine spring return mechanism device provided by the utility model: It includes a connecting shaft 1. A stud 2 is fixedly connected to the right end of the connecting shaft 1. Through the stud 2, a locking nut 3 can be connected to the connecting shaft 1. The outer surface of the stud 2 is threadedly connected with a locking nut 3. Through the locking nut 3, a blocking support can be provided for a pressure spring 4 at the right end of the connecting shaft 1. A pressure spring 4 is arranged on the side surface of the locking nut 3. Through the pressure spring 4, the connection method of the traversing mechanism can be changed from a rigid connection to a flexible connection, so that during the reciprocating movement of the traversing mechanism, it has a certain buffer, thereby eliminating external forces and torque forces and reducing the risk of fracture at the connection. One end of the pressure spring 4 is provided with a rear-end face bearing 5. The inner surface of the rear-end face bearing 5 fits with the outer surface of the connecting shaft 1. The side surface of the rear-end face bearing 5 is movably connected with a nut seat 6. Through the nut seat 6, it can be driven by a connecting sleeve 7 to move, facilitating the compression of the pressure spring 4 under force. The inner surface of the nut seat 6 fits with the outer surface of the connecting shaft 1. The nut seat 6 makes a linear motion along the axial direction of the connecting shaft 1. The right end of the nut seat 6 is threadedly connected with a connecting sleeve 7. The connecting shaft 1, stud 2, locking nut 3, pressure spring 4, and rear-end face bearing 5 are all located inside the connecting sleeve 7. A through hole 8 is opened on the upper surface of the locking nut 3. A threaded connection hole 9 is opened on the outer surface of the stud 2. A fixing screw 10 is arranged inside the through hole 8. The lower end of the fixing screw 10 is threadedly connected with the inside of the threaded connection hole 9. Through the fixing screw 10, the locking nut 3 can be fixed on the stud 2 to prevent the locking nut 3 from loosening after long-term operation. A clamping groove 11 is opened on the inner surface of the nut seat 6. An oil-impregnated bearing 12 is arranged inside the clamping groove 11. The inner surface of the oil-impregnated bearing 12 fits with the outer surface of the connecting shaft 1. Through the oil-impregnated bearing 12, the nut seat 6 has better lubrication when moving on the connecting shaft 1, reducing the friction force and facilitating the movement of the nut seat 6. The side surface of the nut seat 6 is movably connected with a front-end face bearing 13. The inner surface of the front-end face bearing 13 fits with the outer surface of the connecting shaft 1. The front-end face bearing 13 can serve as a buffer between the nut seat 6 and the connecting shaft 1, facilitating the reciprocating movement of the nut seat 6. The left end of the connecting shaft 1 is movably connected with a fixing pin 14. The fixing pin 14 can connect a comb wire drawstring 15 to the connecting shaft 1. The outer surface of the fixing pin 14 is provided with a comb wire drawstring 15. One end of the comb wire drawstring 15 is connected to the connecting shaft 1 through the fixing pin 14, and the other end is connected to a comb assembly. A bolt 16 is movably connected inside the right end of the connecting sleeve 7. The outer surface of the bolt 16 is threadedly connected with a fixing nut 17. The side surface of the fixing nut 17 fits with the right end surface of the connecting sleeve 7. Through the fixing nut 17, the bolt 16 can be fixed on the connecting sleeve 7 to prevent the bolt 16 from moving. And the bolt 16 can be threadedly connected with the traversing mechanism, thereby completing the connection between the comb wire drawstring 15 and the traversing mechanism.

[0024] Working principle: When in use, one end of the combing wire pulling rope 15 is fixed on the connecting shaft 1 through the fixing pin 14, and then the bolt 16 is connected to the transverse movement mechanism to complete the connection between the structures. When the transverse movement mechanism makes a reciprocating movement, it drives the connecting sleeve 7 to make a reciprocating movement, thereby applying pressure to the compression spring 4, causing the compression spring 4 to repeatedly undergo the process of being compressed and restored under force, and eliminating the external force generated during the working process during this process.
