Description

Technical Field

[0001] The utility model relates to a crochet machine, in particular to a balancing mechanism for a crochet machine. Background Art

[0002] A crochet machine, in which the needle bed and the comb are horizontally arranged, and a warp knitting machine with a weft insertion comb vertically arranged above the needle bed is also a variant of a narrow-width Raschel warp knitting machine. The warp yarn fed by the comb is knitted into loops by latch needles or self-closing crochet needles. The weft insertion yarn is fed by the weft insertion comb and clamped in the loops of the ground tissue. It is commonly used for producing narrow-width warp knitted fabrics such as lace tapes and elastic bands. In existing crochet machine products, when the processing mechanism is tilted, the center of gravity shifts, and the edges bear a large load, affecting the use safety and stability. There is a lack of a balance adjustment design that matches the overall structure of the crochet machine, especially a transmission mechanism with strong adaptability. Summary of the Utility Model

[0003] Aiming at the existing technical deficiencies, the utility model provides a balancing mechanism for a crochet machine.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is: a balancing mechanism for a crochet machine, including a driving shaft, a cam, a swing arm, a main shaft, a balance swing frame and a balance connecting rod. Both ends of the swing arm are movably sleeved on the cam and the main shaft. The main shaft and the cam rotate around the driving shaft. The balance swing frame is sleeved on the main shaft and is assembled in a linkage manner. The balance connecting rods are respectively arranged at both ends of the balance swing frame. The balance connecting rods are movably connected to the movable frame for processing production. The balance connecting rods are arranged on the same side of the main shaft and perform moving actions in opposite directions.

[0005] Open holes are provided at both ends of the balance swing frame. An annular connecting portion is provided on the balance connecting rod. A limiting member for movable connection is provided between the connecting portion and the open hole.

[0006] Socket portions for the swing arm to be movably installed are provided on the main shaft and the cam, and the socket portions deviate from the axis.

[0007] The balance swing frame and the balance connecting rods are arranged in pairs and symmetrically at both ends of the main shaft.

[0008] The balance swing frame has a triangular structure. The main shaft is arranged on the axis of the balance swing frame, and the height of the balance swing frame gradually decreases from the middle to both sides.

[0009] Advantages of the utility model: The balancing mechanism for a crochet machine provided by the utility model has a simple and ingenious design. The outer edge of the main shaft is driven to swing relatively left and right by the cam and the swing arm. During the swinging process, the connecting rod pulls on one side relatively to achieve balance adjustment, adapting to the structural layouts of most crochet machine products and meeting the design and use requirements. Description of the Drawings

[0010] Figure 1 is the overall structural schematic diagram of the present utility model;

[0011] Figure 2 is the partial structural schematic diagram of the present utility model. Specific embodiments

[0012] As Figure 1 - Figure 2 shown, a balance mechanism for a crochet machine includes a drive shaft 1, a cam 2, a swing arm 3, a main shaft 4, a balance swing frame 5 and a balance connecting rod 6. Both ends of the swing arm 3 are movably sleeved on the cam 2 and the main shaft 4, and the main shaft 4 and the cam 2 perform a rotary motion through the drive shaft 1. The cam 2 is a common component product. The cam 2 refers to a rotating or sliding part of a machine (such as a wheel or a protruding part of a wheel), which transmits motion to a part moving closely along its edge. Here, the synchronous movement of the swing arm 3 is driven by the cam 2, and the main shaft 4 can be rotated relative to the axis without too many complex designs. The relative swing at the outer edge of the main shaft 4 causes the balance connecting rods 6 on the left and right sides to perform inconsistent supporting or pulling actions, which is beneficial to maintaining the balance of the movable frame. The balance swing frame 5 is sleeved on the main shaft 4 and is assembled in a linkage manner, and can be fastened by means of a positioning key or a pin, etc., and no more elaboration and limitation are made here. The balance connecting rods 6 are respectively arranged at both ends of the balance swing frame 5, and the balance connecting rods 6 are movably connected to a movable frame for production actions. The movable frame is a prior art structure, referring to the relevant mechanism that needs to maintain balance, and no more elaboration and limitation are made here. The balance connecting rods 6 are arranged on the same side of the main shaft 4 and perform moving actions in opposite directions, which is to illustrate the pulling and supporting actions of the balance connecting rods 6 to maintain or adjust the balance, and the angle is adjusted according to preset parameters during specific use.

[0013] Both ends of the balance swing frame 5 are provided with openings, the balance connecting rod 6 has an annular connecting portion, and a limiting member 7 with movable connection is provided between the connecting portion and the opening. Here, it mainly shows that the balance swing frame 5 and the balance connecting rod 6 rotate relatively freely, but do not limit the displacement in all directions, and play an effective supporting role during balance adjustment. The main shaft 4 and the cam 2 are provided with socket portions for the swing arm 3 to be movably installed. The swing arm 3 is beneficial to optimize the layout and improve the practicability. And the socket portion deviates from the axis, so that the rotation of the cam 2 can drive the rotation of the main shaft 4, rather than just displacement. A flange can be set on the main shaft 4 according to needs, without increasing the diameter of the main shaft 4, and it can also meet the requirements such as material strength. It should be noted that compared with flexible connections such as synchronous belts, rigid connections and transmissions are more suitable for use environments with larger loads, ensuring safe, reliable and stable use. In addition, in the initial conditions, the swing arm 3 cannot be set horizontally to avoid affecting normal use, and it is preferably inclined relatively horizontally from left to right. Similarly, the socket only drives displacement, rather than rotation around the center or axis. The balance swing frame 5 and the balance connecting rod 6 are arranged in pairs and symmetrically at both ends of the main shaft 4. Since the braiding machine involves a large number of rods, and the movable frame is the same, the structure here can improve the relative balance and adjust both ends together. The balance swing frame 5 has a triangular structure, the main shaft 4 is arranged on the axis of the balance swing frame 5, and the height of the balance swing frame 5 gradually decreases from the middle to both sides, strengthening the structural strength at this place.

[0014] During specific implementation, the left and right pulling of the balance swing frame 5 is mainly driven by the rotary motion of the main shaft 4 to achieve the supporting balance effect. As the power source input and transmission part, the swing arm 3 and the cam 2 can be replaced by the form of a transmission belt, but this is not the only limitation to it, and it is only described as another embodiment.

[0015] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation to the present invention. At the same time, the basic principles, main features and advantages of the present invention are shown and described above. Those skilled in the art of this industry should understand.
