Problems solved by technology

In the flat knitting machine, it is necessary to pull the fabric through the pulling mechanism to increase the stability of the weaving. Therefore, the stability of the lower pulling mechanism is very important and directly affects the qualified rate of the fabric. At present, most pulling mechanisms are mainly opened by manual operation. The opening and closing of the mechanism is realized by closing the handle. This structure requires manual operation by the worker and cannot be freely opened and closed, and the stability is poor.

Embodiment 1

[0023] The invention provides a lower pulling mechanism for realizing free opening and closing, such as figure 1 , 2 As shown, it includes the first pulling roller C-1a and the second pulling roller C-1b installed on the wall board in reverse through the support plate C-15. The two ends of the first pulling roller are respectively connected to the active opening and closing rod C-8 and the driven opening and closing rod C-7, and the two ends of the second pulling roller are respectively connected to the driven opening and closing rod and the active opening and closing rod. The motor D-1 respectively drives the opening and closing movement between the active opening and closing rod and the driven opening and closing rod at both ends, thereby driving the opening and closing movement of the first and second pulling rollers.

[0024] In the present invention, opening and closing motors are installed on the first and second pulling rollers, which can be opened and closed at the sa...

Embodiment 2

[0026] Such as Figure 4 , 5 As shown, the active opening and closing rod C-8 is connected to the wallboard through the auxiliary shaft C-12, and the active opening and closing rod and the auxiliary shaft are fixed in the circumferential direction; the driven opening and closing rod C-7 is connected to the wall board through the rotating shaft C-11. On the board, the driven opening and closing rod and the active opening and closing rod are connected to each other, and the connection method can be shown in the figure. There is a bearing between the transmission shaft and the driven opening and closing rod, and the bottom ends are engaged with each other. Driven by the opening and closing cam D-3, the active opening and closing lever can swing at a certain angle, and drives the driven opening and closing lever to open or close each other, and the top ends of the driven opening and closing lever and the active opening and closing lever are connected by a tension spring.

Embodiment 3

[0031] Such as Figure 1-3 As shown, the pulling mechanism of the present invention is respectively provided with stepper motor C-17 on the first and second pulling rollers, and the stepping motor drives the gear on the pulling roller to rotate by driving the pulley mechanism. 1. The rotation of the second pulling roller completes pulling the fabric. The pulley mechanism includes a transmission shaft, a driving gear and a driven gear.

[0032] The output shaft end of the stepper motor is provided with a driving gear C-14, and a driven gear C-13 is provided on the outside of the transmission shaft, and the driving gear and the driven gear are meshed with each other; a driven opening and closing rod and a driving pulley are provided on the inside of the transmission shaft The driving pulley C-3 and the transmission shaft are fixed in the circumferential direction, the end of the pulling roller is provided with a driven pulley C-2, the driving pulley and the driven pulley are sl...

Abstract

The invention provides a lower traction mechanism capable of being freely opened and closed. The lower traction mechanism comprises a first traction roller and a second traction roller which are reversely arranged on a wall plate through a support plate, and is characterized in that two ends of the first traction roller are respectively connected with a driving opening and closing rod and a driven opening and closing rod, two ends of the second traction roller are respectively connected with the driven opening and closing rod and the driving opening and closing rod, and an opening and closing motor drives the driving opening and closing rod and the driven opening and closing rod at the two ends to do opening and closing motion so as to drive the first traction roller and the second traction roller to do opening and closing motion. Free opening and closing of the lower traction mechanism are achieved, the opening and closing motor of the lower traction mechanism controls a cam to rotate so that free opening and closing can be achieved, the opening and closing angle can be adjusted according to the situation that the thickness of a fabric is different, and a stepping motor controls the traction roller to rotate so that the tension acting on the fabric can be kept constant.

Description

technical field [0001] The invention belongs to the technical field of flat knitting machines, in particular to a lower pulling mechanism for realizing free opening and closing. Background technique [0002] As flat knitting machines are used more and more widely, people's performance requirements for computerized flat knitting machines are also getting higher and higher. In the flat knitting machine, it is necessary to pull the fabric through the pulling mechanism to increase the stability of the weaving. Therefore, the stability of the lower pulling mechanism is very important and directly affects the qualified rate of the fabric. At present, most pulling mechanisms are mainly opened by manual operation. The opening and closing of the mechanism is realized by closing the handle. This structure requires manual operation by workers and cannot be freely opened and closed, and the stability is poor. [0003] Therefore, there is an urgent need for a lower pulling mechanism cap...
