Description

Technical Field

[0001] The utility model belongs to the technical field of textile machinery, and particularly relates to a high-speed double needle bed warp knitting machine. Background Art

[0002] The high-speed double needle bed warp knitting machine is equipped with two needle beds, and can knit fabrics with different layers and structures under high-speed operation, with the characteristics of high efficiency and high quality in production. This kind of machine is widely used in the manufacture of functional fabrics, such as breathable, warm or protective materials, and is suitable for application fields such as sportswear, underwear, medical materials, etc. With the continuous progress of textile technology and the change of market demand, the high-speed double needle bed warp knitting machine is also constantly innovating and developing to adapt to a wider range of application fields and higher production requirements.

[0003] In the existing double needle bed warp knitting machines, the loop-forming mechanism and the reciprocating driving device of the comb device are mainly the following three types:

[0004] (1) Fully cam-driven. Due to the limitation of the movement path of the rocker, the cam used to drive the comb rocker movement can only be a triangular cam. Since there are inflection points on the triangular cam, vibration noise will be generated during the movement of the triangular cam, and long-term impact and collision are likely to cause wear and damage to components such as the cam and knitting needles. Moreover, the triangular cam severely limits the knitting speed and cannot achieve knitting speed increase.

[0005] (2) Fully eccentric wheel-driven. As a regular circular component, the stroke path of the eccentric wheel naturally shows a certain regularity, which severely restricts the diversity of the movement laws of the needle parts. In addition, when the knitting stroke increases, the required eccentricity of the eccentric wheel also increases. However, the installation space inside the machine frame is very limited, and it is difficult to meet the space installation requirements of the large-stroke warp knitting machine.

[0038] In this embodiment 1, the specific structure of the reciprocating drive device 4 is as follows:

[0039] like Figure 2 As shown, the front vehicle main shaft drive 4-2 and the rear vehicle main shaft drive 4-3 are symmetrically arranged on the frame 1, the front vehicle secondary shaft drive 4-4 and the rear vehicle secondary shaft drive 4-5 are symmetrically arranged on the frame 1, and the front vehicle main shaft drive 4-2 is transmission-connected with the front vehicle secondary shaft drive 4-4, the front vehicle main shaft drive 4-2 provides power to the front vehicle secondary shaft drive 4-4, the rear vehicle main shaft drive 4-3 is transmission-connected with the rear vehicle secondary shaft drive 4-5, the rear vehicle main shaft drive 4-3 provides power to the rear vehicle gear pair 4-7, and the power drive 4-1 synchronously drives the front vehicle main shaft drive 4-2 and the rear vehicle main shaft drive 4-3 to work.

The front vehicle gear pair 4-6 includes a front main gear 4-61 and a front auxiliary gear 4-62. The front main gear 4-61 and the front auxiliary gear 4-62 are respectively installed on the front main shaft 4-21 and the front auxiliary shaft 4-41, and the two are meshed with each other. The rear main shaft drive 4-3 drives the rear auxiliary shaft drive 4-5 to work through the rear vehicle gear pair 4-7. The rear vehicle gear pair 4-7 includes a rear main gear 4-71 and a rear auxiliary gear 4-72. The rear main gear 4-71 and the rear auxiliary gear 4-72 are respectively installed on the rear main shaft 4-31 and the rear auxiliary shaft 4-51, and the two are meshed with each other. In addition, in this Embodiment 1, the installation positions of the front vehicle gear pair 4-6 and the rear vehicle gear pair 4-7 can be adjusted according to actual needs, and preferably at the end of the frame.

[0041] Those skilled in the art can control the transmission speed ratio by controlling the transmission ratios of the front vehicle gear pair 4-6 and the rear vehicle gear pair 4-7. In this Embodiment 1, the transmission speed ratios of the front vehicle gear pair 4-6 and the rear vehicle gear pair 4-7 are both 1:3, that is, when the main shaft rotates one circle, the auxiliary shaft can rotate three circles. Therefore, in this utility model, the movement speeds of the looping device and the comb device can be flexibly adjusted by adjusting the transmission ratio.

[0042] In this utility model, the front vehicle gear pair 4-6 and the rear vehicle gear pair 4-7 can also be replaced by those skilled in the art according to needs with existing transmission components such as sprocket transmission pairs and synchronous pulley transmission pairs that can realize the transmission connection between two shafts.

[0043] As Figure 3 shown, the front main shaft drive 4-2 includes a front main shaft 4-21, a front vehicle sinker cam 4-22 and a front vehicle needle bed cam 4-23. The front main shaft 4-21 is rotatably installed on the frame 1. The front vehicle sinker cam 4-22 and the front vehicle needle bed cam 4-23 are both installed on the front main shaft 4-21. The front vehicle sinker cam 4-22 is connected in cooperation with the cam swing arm 2-11 of the front vehicle sinker mechanism 2-1, and the front vehicle needle bed cam 4-23 is connected in cooperation with the cam swing arm 2 of the front vehicle needle bed mechanism 2-3.

[0044] As Figure 3 shown, the rear main shaft drive 4-3 includes a rear main shaft 4-31, a rear vehicle sinker cam 4-32 and a rear vehicle needle bed cam 4-33. The rear main shaft 4-31 is rotatably installed on the frame 1. The rear vehicle sinker cam 4-32 and the rear vehicle needle bed cam 4-33 are both installed on the rear main shaft 4-31. The rear vehicle sinker cam 4-32 is connected in cooperation with the cam swing arm of the rear vehicle sinker mechanism 2-2, and the rear vehicle needle bed cam 4-33 is connected in cooperation with the cam swing arm of the rear vehicle needle bed mechanism 2-4.

[0045] AsFigure 2 As shown in the figure, a front vehicle belt pulley 4-24 is installed at one end of the front vehicle main shaft 4-21, a rear vehicle belt pulley 4-34 is installed at one end of the rear vehicle main shaft 4-31, and the front vehicle belt pulley 4-24 and the rear vehicle belt pulley 4-34 are connected by a first synchronous belt 4-8. One end of the front vehicle main shaft 4-21 or the rear vehicle main shaft 4-31 is in transmission connection with the power output end of the power driving member 4-1.

[0046] In the present utility model, the front vehicle belt pulley 4-24 and the rear vehicle belt pulley 4-34 for driving the looping mechanism to move reciprocally rotate in the same direction (both clockwise or counterclockwise). Compared with the traditional synchronous pulleys rotating in opposite directions (one clockwise and one counterclockwise) for transmission, the transmission efficiency is higher and the vehicle speed is faster. This is because when rotating in the same direction, the cooperation between the synchronous belt and the synchronous belt pulley is smoother and the friction is smaller, thereby reducing energy loss.

[0047] In order to prevent the first synchronous belt from slipping, improve the transmission efficiency, and maintain the stability of product conveyance, in Embodiment 1, a plurality of pressing wheels 4-81 are further provided on the two outer sides of the first synchronous belt 4-8, and the pressing wheels 4-81 are in close contact with the outer side of the first synchronous belt 4-8. The pressing wheels apply tension to the first synchronous belt 4-8 through friction, ensuring that the first synchronous belt 4-8 will not slip due to insufficient tension during transmission, thereby maintaining the stability and accuracy of transmission. At the same time, under the action of the pressing wheels 4-81, the first synchronous belt 4-8 can better fit the front and rear vehicle belt pulleys, reducing energy loss caused by gaps or looseness, thereby improving the transmission efficiency. In Embodiment 1, the tension of the first synchronous belt 4-8 can also be effectively adjusted by adjusting the pressing wheels, ensuring that it maintains an appropriate tension during transmission, which helps to extend the service life of the synchronous belt and reduce failures caused by improper tension.

[0048] As Figure 3 shown, the front vehicle auxiliary shaft driving member 4-4 includes a front vehicle auxiliary shaft 4-41 and a front vehicle rocker eccentric wheel 4-42. The front vehicle auxiliary shaft 4-41 is rotatably installed on the frame 1, the front vehicle rocker eccentric wheel 4-42 is installed on the front vehicle auxiliary shaft 4-41, and the connection end of the front vehicle rocker eccentric wheel 4-42 is connected to the front rocker mechanism 3-1.

The rear vehicle auxiliary shaft 4-51 is rotatably installed on the frame 1, the rear vehicle rocker eccentric wheel 4-52 is installed on the rear vehicle auxiliary shaft 4-51, and the connection end of the rear vehicle rocker eccentric wheel 4-52 is connected to the rear rocker mechanism 3-2. The rear vehicle auxiliary shaft 4-51 is in transmission connection with the rear vehicle main shaft 4-31 through a rear vehicle gear pair 4-7.

[0050] As shown Figure 2 in Figure [Figure number not provided], the power driving member 4-1 includes a driving motor 4-11, a main driving wheel 4-12, and a secondary driving wheel 4-13. Among them, the driving motor 4-11 is installed on one side of the frame 1, and the output end of the driving motor 4-11 is drivingly connected to the main driving wheel 4-12. The secondary driving wheel 4-13 is coaxially installed with the front vehicle spindle driving member 4-2 or the rear vehicle spindle driving member 4-3, and the main driving wheel 4-12 and the secondary driving wheel 4-13 are connected by a second synchronous belt 4-9.

[0051] As shown Figure 5 in Figure [Figure number not provided], the front rocking frame mechanism 3-1 includes a front rocking frame connecting rod 3-11, a front comb rocking frame assembly 3-12, a front rocking frame support 3-13, and a front eccentric wheel connecting rod 3-14. The top end of the front rocking frame connecting rod 3-11 is connected to one end of the front comb rocking frame assembly 3-12. The bottom end of the front rocking frame connecting rod 3-11 and the front eccentric wheel connecting rod 3-14 are both movably connected to the connecting end of the front rocking frame support 3-13. The front eccentric wheel connecting rod 3-14 is installed on the outer contour of the front rocking frame eccentric wheel through a bearing, and the front rocking frame support is rotatably connected to the frame.

[0052] The specific structure of the rear rocking frame mechanism 3-2 is the same as that of the front rocking frame mechanism 3-1, and its installation method is also the same as that of the front rocking frame mechanism 3-1, and it is ensured that the movements of the front rocking frame mechanism 3-1 and the rear rocking frame mechanism 3-2 are consistent.

[0053] In the present utility model, the contour lines of the front vehicle sinker cam 4-22, the front vehicle needle bed cam 4-23, the rear vehicle sinker cam 4-32, and the rear vehicle needle bed cam 4-33 are designed according to the movement paths of the front vehicle sinker mechanism 2-1, the front vehicle needle bed mechanism 2-3, the rear vehicle sinker mechanism 2-2, and the rear vehicle needle bed mechanism 2-4, respectively.

[0054] In the present utility model, the eccentric designs of the front vehicle rocking frame eccentric wheel 4-42 and the rear vehicle rocking frame eccentric wheel 4-52 are designed according to the swinging paths of the front comb rocking frame assembly 3-12 and the rear comb rocking frame assembly, respectively.

[0055] In the present utility model, the front vehicle belt pulley 4-24, the rear vehicle belt pulley 4-34, and the first synchronous belt 4-8 cooperate to form a synchronous transmission assembly. The main driving wheel 4-12, the secondary driving wheel 4-13, and the second synchronous belt 4-9 cooperate to form a synchronous transmission assembly. It can also be replaced by a sprocket transmission pair, a gear transmission pair, or other existing transmission assemblies that can achieve two-axis synchronous transmission connection by those skilled in the art according to requirements. And the number of wheel parts (belt pulleys, gears, sprockets, etc.) used for transmission can be set according to actual needs, which belongs to conventional technical means.

[0056] In Embodiment 1, the working principle of the looping device and the comb device moving reciprocally is as follows:

[0057] When the driving motor 4-11 works, the auxiliary driving wheel 4-13 installed on the front vehicle main shaft 4-21 is driven to rotate by the main driving wheel 4-12 via the second synchronous belt wheel 4-9. The front vehicle main shaft 4-21 rotates accordingly, and then drives the front vehicle belt wheel 4-24 to rotate, and drives the rear vehicle belt wheel 4-34 to rotate through the first synchronous belt 4-8. The rear vehicle main shaft 4-31 is driven to rotate by the rear vehicle belt wheel 4-34.

[0059] The rotation of the rear vehicle main shaft 4-31 can drive the rear vehicle sinker cam 4-32 and the rear vehicle needle bed cam 4-33 to rotate simultaneously. Among them, the rear vehicle sinker cam 4-32 drives the rear vehicle sinker mechanism 2-2 to move reciprocally through the cam swing arm, and the rear vehicle needle bed cam 4-33 drives the rear vehicle needle bed mechanism 2-4 to move reciprocally through the cam swing arm.

[0060] The rotation of the front vehicle auxiliary shaft 4-41 can drive the front vehicle rocker eccentric wheel 4-42 to rotate, thereby driving the front rocker link 3-11 to move reciprocally through the front eccentric link 3-14 via the front rocker support 3-13, and driving the front comb rocker assembly 3-12 to swing reciprocally around the rocker rotation center. The working principle of the rear rocker mechanism 3-2 is the same as that of the front rocker mechanism 3-1.

It should be noted that for those of ordinary skill in the art, without departing from the premise of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
