Description

The network shedding machines are known, consisting of kinematically connected common actuator for spreading and opening the extremities of the net nolot, nasal thread iodine mechanism through the web of rolls, nodal pick rollers, and a mechanism for forming a closed net of the harness on the selection.

The proposed net masking machine differs from the known ones in a simpler design, as well as in the fact that it provides fixation of the nodes on the selection.

The peculiarity of the machine is that in front of the mechanism for forming a closed net of the planting thread there is a device for pulling the double planting thread through the toolbox, and the device for straightening and opening the outermost ones of the web is made in the form of a slit with a longitudinal groove.

The device for pulling the dual planting thread through the selection is made in the form of a hook with a pointed end, mounted on the rod, which is connected by means of a connecting rod with a disk having a profiled groove on the side surface, and is equipped with a pusher and an unloader of the planting thread. The latter are made in the form of a fork mounted on a holder, at the end of which there is a finger

with a key interacting with the disc slot.

The mechanism for the formation of a closed net is composed of tongs and an arcuate pusher mounted on sliders. The latter are equipped with rollers interacting with shaped grooves of a cylindrical cam.

FIG. 1 is a diagram of a network planter; in fig. 2 is a diagram of the node of the netting net and the selection; in fig. 3 is a schematic of a device for straightening and opening the outermost web in two projections; in fig. 4 is a diagram of a mechanism for forming a closed loop of a planting thread on the selection in three projects.

All maschine mechanisms are driven by an electric motor / via gear 2 and main shaft 3.

Net fabric 4 and rebounds 5 are fed through the Maltese cross 6 in accordance with the landing ratio of two discs 7 and 8, on which there are grooves for selection.

The disk 7 is mounted on the same shaft 9 with the Maltese cross, and the disk 8 is mounted on a separate shaft JO, which is rotated via a valuable gear from the shaft 9.

It is driven through a driving sprocket 11, mounted on shaft 9, n driven sprocket 12 on shaft 13. On chain links 14, spanning sprockets 11 and 12, fingers 15 are fastened, the distance between which corresponds to the landing pattern and exceeds the length of the closed loop of fitting thread. on the selection. The fingers 15 in the upper portion of the trajectory occupy a vertical position, and pass through the notch of the rail 16, capturing the required number of extreme net webs to form one closed loop of the fitting thread 17. To keep the fingers 15 in the indicated portion in vertical position, rollers are installed at their ends 18 (see Fig. 2), moving in the same area along the guide bar 19. At the exit from it, the fingers 1, at assortment / springs 20 (see Fig. 3), rotate and lower the end cages of the net fabric, which are worn before landing. and rail 16.

The rail 16 is made with a longitudinal thread 21 for the landing thread 17, the feed of which is regulated by the clamp 22. The collars 5 are mounted on the disk 7 by the rollers 23.

For pulling the dual planting thread through the selection machine is equipped with a device located in front of the mechanism for forming a closed loop of the planting thread and consisting of a hook 24 with a pointed end, a pusher 25 and an selector 26.

The hook 24 is fastened to the rod 27, which receives a straight-line reciprocating movement through the rod 28, which is connected to a disk 29 having a shaped groove on its side surface.

A pusher 25, made in the form of a fork, is mounted on a holder having a roller 30 at the end, and is driven from a disk 29 by the interaction of a roller with a disk.

The releaser 26 is arranged similarly to the pusher 25 and moves in the interaction of the roller 32 fixed on the pulling hook 31 with the groove of the same disc 29.

The screw 33 adjusts the position of the hook 24 but vertical. The mechanism for forming the closed loop of the planting thread on the pickup is driven by a chain drive 34 with a pressure sprocket 35 and includes the following main operating members: tongs 36, an arcuate pusher 37. and a cylindrical cam 38 with two profiled ends.

In one groove, a roller 39 is mounted, fixed on a slider 40, through which a finger-pin 41 is reciprocated by forceps 36 with a spring 42. In the other groove of a cam 38 nepeMontaeT roller 43 fixed on a slider 44. The roller axis moves in a gaining 45 The slider 44 through the finger 46 and the toothed sector 47 transmits the movement of the arcuate pusher 37.

A guide rail 48 is designed to hold the net 4 in a horizontal position (see Fig. 2).

Networks are landing as follows. When the main shaft 3 is rotated one turn by one, the Maltese cross makes (4 turns), and the necessary amount of netting 4 and the selection 5 are delivered.

During the next Vi rotation of the shaft 5, when the feed mechanism does not work, the pusher 25 moves the landing thread down and the hook 24 passes through selection 5, grabs the landing thread loop from the pusher 25 and pulls it through the selection. When the hook 24 moves back, the release 26 removes the loop from the hook. After that, the nodache mechanism begins to work, and the process of forming a closed loop is repeated.

At the same time, with this, the arcuate pusher 37 throws a loop around the pick-ups onto the tongs of the tongs 36, which seize the loop that has been transferred and then tighten the landing unit. For each revolution of the main shaft 3, one knot is tightened.
