[0044] The cloth-rolling drum opening and closing swing arm left rear 8 and the cloth-rolling drum opening and closing swing arm left front 9 are respectively fixed to the first cloth-rolling drum 74 and the second cloth-rolling drum 75, and the cloth-rolling drum opening and closing swing arm left rear 8 is movably connected to the cloth-rolling drum opening and closing control cam 6 through a connecting plate;

[0045] The cloth-rolling drum driving motor 71 and the cloth-rolling drum opening and closing driving motor 2 are both connected to an external power source and a control switch;

[0046] The left rear 8 and the left front 9 of the cloth rolling drum opening and closing swing arm are both rotated by a rotating shaft (not shown) during the rotation process, serving as a rotation point to improve the stability of the rotation;

[0047] The first cloth-rolling drum 74 and the second cloth-rolling drum 75 can be designed to be plum blossom-shaped drums or bare cylinders according to the traction requirements of the fabric, and rough surface tapes can be pasted on the cylindrical surfaces.

[0048] A round head 10 is provided on one side of the left rear 8 of the cloth rolling drum opening and closing swing arm, and a U-shaped groove 11 is provided on one side of the left front 9 of the cloth rolling drum opening and closing swing arm.

[0055] The working principle of the traction mechanism of the fully computerized flat knitting machine provided by the present invention is as follows:

[0056] Step 1: During the roller adjustment process, the cloth rolling drum opening and closing driving motor 2 is first started, so that the first cloth rolling drum opening and closing transmission gear 3 on the output shaft of the cloth rolling drum opening and closing driving motor 2 rotates, and through the meshing relationship, the second cloth rolling drum opening and closing transmission gear 4 is driven to rotate accordingly, thereby driving the cloth rolling drum opening and closing transmission shaft 5 to rotate, so that the cloth rolling drum opening and closing control cam 6 also rotates accordingly, thereby driving the cloth rolling drum opening and closing swing arm left rear 8 to swing;

[0057] The second step: by pushing and squeezing, the left front opening and closing swing arm 9 of the cloth rolling drum also swings, so that the first cloth rolling drum 74 and the second cloth rolling drum 75 are opened, and then the bottom lifting device is driven to rise to the needle bed position, and the woven cloth is first pulled down. When the bottom lifting device reaches below the first cloth rolling drum 74 and the second cloth rolling drum 75, the cloth rolling drum opening and closing drive motor 2 is started again, and the cloth rolling drum opening and closing transmission shaft 5 is controlled to close, and then the cloth rolling drum drive motor 71 is started to control the rotation of the traction mechanism, replacing the bottom lifting device to pull the woven cloth down.

[0058] Compared with the related art, the traction mechanism of the fully computerized flat knitting machine provided by the present invention has the following beneficial effects:

[0059] The traction mechanism has an adjustment function. By adjusting the distance between the first cloth-winding drum 74 and the second cloth-winding drum 75, it is suitable for weaving yarns of different types, which not only improves the scope of use but also improves the flexibility of the traction mechanism.

[0060] Second embodiment

[0061] Please refer to Figure 5Based on the traction mechanism of the fully computerized flat knitting machine provided in the first embodiment of the present application, the second embodiment of the present application proposes another traction mechanism of the fully computerized flat knitting machine. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0062] Specifically, the traction mechanism of the fully computerized flat knitting machine provided in the second embodiment of the present application is different in that: a scale 17 is provided on one side of the frame 1, a marking block 18 is fixedly connected to the spring adjustment screw 15 of the cloth winding drum opening and closing swing arm, and one side of the marking block 18 is slidably connected to the scale 17;

[0063] By setting the scale 17, the marking block 18 is driven to slide on the scale 17 when the cloth winding drum opening and closing swing arm spring adjusting screw 15 moves, so that the moving distance of the cloth winding drum opening and closing swing arm spring adjusting screw 15 can be recorded, so that the next time the same batch of yarn is processed, it can be directly adjusted to the previous position for processing.

[0064] Third embodiment

[0065] Please refer to Figure 6-8 Based on the traction mechanism of the fully computerized flat knitting machine provided in the first embodiment of the present application, the third embodiment of the present application proposes another traction mechanism of the fully computerized flat knitting machine. The third embodiment is only a preferred embodiment of the first embodiment, and the implementation of the third embodiment will not affect the independent implementation of the first embodiment.

[0066] Specifically, the traction mechanism of the fully computerized flat knitting machine provided in the third embodiment of the present application is different in that: the inner surface of the U-shaped groove 11 is provided with a flow groove 19, and the adjacent flow grooves 19 are connected through the flow holes 20;

[0067] The adjacent holes are connected to facilitate the flow of lubricating oil, and the upper and lower sides of the flow holes 20 are both set to be open to increase the amount of lubricating oil entering.

[0068] The U-shaped groove 11 is provided with an oil filling hole 21 for filling lubricating oil. The shape of the oil filling hole 21 is funnel-shaped, and is wide at the top and narrow at the bottom. The bottom of the oil filling hole 21 is connected to the inside of the flow groove 19.

[0069] The oil filling hole 21 is funnel-shaped and is designed to be wide at the top and narrow at the bottom, thereby increasing the amount of lubricating oil entering and improving the lubrication effect.

[0070] The lubricating oil enters through the oil filling hole 21, and diffuses into the interior of the flow groove 19 due to the action of gravity, and through the connected flow holes 20, the lubricating oil expands the flow area until it is distributed in the flow groove 19. When the round head 10 contacts the U-shaped groove 11, it directly contacts the lubricating oil distributed in the flow groove 19 to achieve lubrication of the round head 10, reduce the contact friction between the two, and avoid excessive friction, which may easily cause abnormal noise.

[0071] Reinforcing ribs 22 are provided on both sides of the flow groove 19 and at the edge of the U-shaped groove 11 to reinforce the U-shaped groove 11 .

[0072] Fourth embodiment

[0073] Please refer to Fig. 9 Based on the traction mechanism of the fully computerized flat knitting machine provided in the first embodiment of the present application, the fourth embodiment of the present application proposes another traction mechanism of the fully computerized flat knitting machine. The fourth embodiment is only a preferred embodiment of the first embodiment, and the implementation of the fourth embodiment will not affect the independent implementation of the first embodiment.

[0074] Specifically, the traction mechanism of the fully computerized flat knitting machine provided in the fourth embodiment of the present application is different in that: a first gear 24 is rotatably connected to one side of the left front 9 of the opening and closing swing arm of the cloth rolling drum, a second gear 23 is rotatably connected to one side of the left rear 8 of the opening and closing swing arm of the cloth rolling drum, and an outer surface of the first gear 24 is meshed with an outer surface of the second gear 23;

[0075] The meshing between the first gear 24 and the second gear 23 improves the stability of the distance movement between the first cloth rolling drum 74 and the second cloth rolling drum 75 .

[0076] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
