Description

2. The device according to Claim 1, in connection with the fact that it is equipped with the podruhinennyi pinch rollers mounted on the deflecting faces of the funnel on its outer side, whose axes

located in

swing plane

funnels. . .

3. The device according to Claim 1, about which the drive for swinging the funnel is made in the form of a link-lever mechanism.

  one

The invention relates to the processing of polymeric materials and can be used primarily in the processing of rubber compounds in the process of obtaining narrow bands for feeding worm machines.

The purpose of the invention is to reduce the metal content and power consumption of the device. . -.

Figure 1 shows the device, a general view: figure 2 - view A in figure 1.

. The device contains a feed conveyor 1 and a frame 2 on which a conveyor 3 with a drive (not shown) is fixed for moving material loops hung on it in a cooling chamber. Above the inlet, a conveyor belt 3 is located along the material movement and below the feed conveyor 1. A means for deflecting the material and hanging its loops on the conveyor 3, which is made in the form of a guide cone 4, mounted for swinging in a vertical plane. perpendicular to the movement of the loops of the material in the cooling chamber, and rigidly connected; with the funnel 4 of the mechanism for swinging it. The latter includes a pneumatic cylinder 5 fixed on frame 2, crank 6, pivotally connected to rod 7 of pneumatic head 5, and connected at one end to crank 6 through slide 8 of a slider 9, the other end mounted with the possibility of free movement in link 10, which is mounted naosi 1 1, fixed to the frame2.

The feed conveyor 1 has a pressure roller 12 ..

The guide funnel is rigidly mounted on the slider 9 by means of the tabs 13. On the deflecting faces x 14

And 15 of the guide funnel 4 is fixed to the hinge supports 16 and 17, on which rollers 18 and 19 are mounted, suspended on springs 20 and 21, the axes of the rollers being in a plane perpendicular to the conveyor 3. The cooling chamber is mounted inside frame 2 and includes spaced successively along the conveyor 3 sections 22 and 23, respectively, for blowing and irrigation. For the selection of the cooled ribbon material, there is a pallet 24 installed along the outlet section of the conveyor 3 at the outlet of the blowing section.

The device works as follows.

The heated polymer material, for example, rubber tape 25, is removed from the rollers (not shown) and fed to the feeding conveyor 1 {figure 1 and 2}. The tape 25 falls under the pressure roller 12 and is fed between the deflecting faces 14 and 15 of the guide funnel 4 fixed on the legs 13. of the slide 9..

Under the action of the pneumatic cylinder 5, the slider 9, and with it the direction of the funnel 4, make a complex movement along the trajectory enveloping the conveyor. ter 3 for moving the loops of the material (in Fig. 2 the left and middle positions of the guide funnel 4 are shown by dashed lines).

Conveyor 3 is in constant motion. The loops of the rubber tape are formed due to the interaction, the subsequent conveyor 3 and one of the deflecting faces of the guide funnel 4 when the latter rotates in a vertical plane. When this occurs around the ribbon 25 of the conveyor 3, the rollers.
