Abstract

The invention relates to tricot and mechanical engineering, and more specifically to a multi-bed base, to slot machines equipped with slotting tongs, and allows to simplify the machine and increase its productivity. For this basis, the machine is equipped with slotted needles, it does not have lugs and the enclosing plates are fixed. The slot needles and their locking devices receive movement from the six-hinged-lever mechanisms, in which the crank and the connecting rod are common. The rolling motion, the ridge, the slot needles and the securing devices are obtained from six-link articulated lever mechanisms, in which the four-door link is common. All mechanisms are mounted in a box installed on the machine frame. 1 hp ff. 6 Il. 3

Description

The invention relates to a knitting machine building industry, namely to multi-casting foundations for felting machines equipped with slotted needles.

The aim of the invention is to prevent; Insulation of the basics of the machine and increase of its productivity.

Figure 1 shows the mechanisms of the drive of the loop-forming organs of the foundations of the filling machine, general view; figure 2-4 shows the kinematic diagrams of the mechanisms for driving the loop-forming organs; Fig. 5 is a combined diagram of the movement of the loop-forming organs; Fig. 6 shows the relative trajectory of movement of the loop-forming organs of the foundations of the die machine.

On the main shaft 1 of the base of the die machine (Fig. 1), an eccentric 2 of the reciprocating movement of the slot-needle and the contactors is fixed, connected to the connecting rod 3 also common to two mechanisms, the other end of which is pivotally connected to the double-arm rocker lever C mounted support 5- The other arm of the lever V through the intermediate link 6 is pivotally connected to the double-arm lever 7, the other end of which is pivotally connected to the lever 8 carrying the needle bar 9 with the blocks 10 installed on it with the mortise needles 11 (Fig.2-4). The eccentric 2 and the connecting rod 3 are in common with the reciprocating mechanism of the closer. The kinematic schemes of these mechanisms are identical. A double-arm lever-beam 12 mounted on support 5 is pivotally connected to the connecting rod 3. The other arm of the lever 12 is pivotally connected to the double-shouldered lever 14 through the connecting link 13, the other end of the arm

Secondly, it is pivotally connected to the lever 15 carrying the bar 16 with the contactors 1. A six-linking hinge-lever mechanism based on a four-joint element, which is common, is used to implement the swinging motion of the breaking ridge along with the mortise needle and the contactors; for all three mechanisms.

An eccentric 18 of the mechanisms of the oscillating movement of an otboyny crest, a mortise needle and a buckle, connected to a connecting rod 19, the other end of which is pivotally connected to the double-shouldered rocker arm 20, is fixed on the main shaft 1 of the founding machine base (Fig.1-). mounted on a pole. The other arm of the lever 20 through the intermediate link 21 is pivotally connected to the lever 22, which is movably mounted on the support 23. At the end of the lever 22, a fender bar 2k with blocks 25 fixed on it with fender plates 26 is rigidly mounted. Through the intermediate lever 27 from link 20, movement is transmitted to needle bed, and through the lever 28 - zamkatel m.

All mechanisms of the machine are mounted in a separate box and work in an oil bath. The box is installed on the machine frame. The number of boxes installed on the machine is consistent with the working width of the needle case. The bar 29 of the enclosing plates 30 is fixed on the machine frame. The main shaft 1 of the base of the machine is movably mounted in bearings 31 mounted on the frame.

The machine works as follows.

The combined diagram of the movement of the loop-forming organs of the proposed multi-die base of the dummy machine (Fig. 5) shows the graph 32 of the reciprocating movement of the mortise needle 11, the graph 33 of the oscillatory motion of the baffle 26 and the mortise needle and the contactors; graph 3 of the reciprocating motion of the sliders 17. To prove the operability of the proposed fundamentals of the die machine, the relative trajectories of their motion are plotted according to the graphs of the motion of the loop-forming organs shown in Fig. 5 (Fig. 6). Figure 6 shows the mutual position of the loop-forming organs ma0.

tires with stationary locking plates 30 and ear combs that have no movement in the direction of pumping, but which only perform longitudinal movements.

The holes 35 in the three shear lines form the ground, and the ears 36 in the seven shear lines form the pattern. The designation of points on the x trajectory (Fig. 6) corresponds to parts of the loop formation cycle from 0 to 12, shown in the graphs of the movement of the loop-forming organs (Fig. 5). The relative trajectories of movement of the loop-forming organs show the mutual position they occupy relative to each other in the loop-forming process.

The movement of the groove needle 11 (Fig. 6) with respect to the tabs 35 and 36, which have no movement in the direction of flow and with respect to the fixed confinement plates 30, is represented by a closed curvilinear trajectory 37. Fig. 6 shows the trajectory 38 of the movement of the baffle edge ridge 26. Trajectory 39 is given to build a trajectory 38 and corresponds to the movement of the slot needle 11 during its swinging movement. The picture of the relative trajectories of the movement of the loop-forming organs makes it possible to assess how well the movements in question meet the requirements of the technology in the downhole. Thus, in section 0-3 (curve 37), the head of the needle 11, interacting with the lower edge of the fixed confining plate 30, provides an operation of the conclusion. In section 2-7, the needle head interacts correctly with the tabs 35 and 36, ensuring that the thread is laid on the needle core. On the site (the curve of the needle 11 interacts with the ground ears 35, ensures the laying of the thread under the needle hook. Section 10-0 (curve 37) characterizes the correct interaction of the needle with the tip of the trailing plate 30.

Thus, the proposed base machine reliably implements the technological process, and its main mechanisms are efficient.

The positive effect from the industrial application of the proposed multi-die bases of the die machine is obtained by simplifying the drive mechanisms of the loop-forming organs and increasing the productivity

cars. A common crank and a connecting rod for two mechanisms and a common four-link for three mechanisms and a reduction in the ringing of all mechanisms reduce the cost of the machine as a whole.
