Abstract

The invention relates to devices for the machining of plastic products having the form of rotation bodies. The purpose of the invention is to increase the reliability and productivity. For this, the device is equipped with a spring-loaded damper, made in the form of a rotatable vertical axis with perpendicular arms fixed at its ends. The output end of the loading unit tray is rounded in the direction of rotation of the rotor. And the shoulders of the valve are located across the rounded portion of the tray. The upper shoulder is located above the upper end of the nest for products, and the lower shoulder is above the lower end of the nest. In addition, the rotor shaft is rigidly fixed, the rotor is mounted on it on the support. The cams are made on this shaft and are associated with the tool. 1 hp f-ly, 4 ill.

The invention relates to devices for the machining of plastic products and can be used in the processing of products having the form of rotating bodies.

The purpose of the invention is to increase the reliability and productivity.

FIG. 1 shows the device, a general view (rotated 90 °); in fig. 2 is a view A of FIG. one; in fig. 3 is a section BB in FIG. 2; in fig. 4 - orientation scheme: product after loading it into the slot; product unloading scheme after mechanic treatment.

The device consists of a housing 1, on which an axis 2 is installed, carrying cylindrical cams 3 rigidly fixed on it and mounted on a rotor 4 on supports and with sockets 5 for products and and (pindel 6, whose working parts with cutting tools 7 interact with | cams 3 by means of rollers 8.

The housing 1 also has a loading unit 9 consisting of a hopper 10, a disk 1 I with through slots 12, a shaft 13, a tray 14 with a rounded section 15 and a flap 16 having the upper 17 and lower 18 shoulders, which are pivotally fixed on the vertical axis 19 and fitted with a spring 20.

The drive of the device includes a camshaft 21 connected to an electric motor (not shown) and carrying the fixedly mounted pins 22 connected to the pins 23 on the spindle x 6 and the fixedly mounted gear 24 connected to the rotor gear 25 of the rotor 4 and the gear 26 mounted on the shaft 27 through a sleeve 28 coupled to the shaft 13 of the loading unit. In the lower part of the sockets 5, holes 29 are uniformly circumferentially made, and in the upper part of the rotor axis 4, holes 30 (Fig. 4) are connected, respectively, by ducts 31 and 32, respectively, with the air distributor 33, times 1cc, on axis 2.

The device works as follows.

From camshaft 21 through gears 24 and 26, rotation is transmitted to shaft 27, and from it through coupling 28 to shaft 13, on which the disk I.P) is fixed, and this product 34, located in the hopper 10, is caught by through slots 12 disc 11, is entrained by tray 14 and alternately dumped into it. Moving to the tray 14, the products 34 fall into the fixed portion 15, hit its wall and extinguish their kinetic energy.

The rotor 4, loosely mounted on the axis 2, rigidly fixed in the housing 1, through

The ring gear 25 and gear 24 connected to the camshaft 21 rotates continuously at a constant angular speed. In this case, the sockets 5 pass under the products 34, which are located in the arcuate section 15, and capture them. The flap 16, pivotally mounted on the axis 19 and spring-loaded by the spring 20, drops its products 34 into the slots 5 with its upper arm 17 when they are dropped from the tray 14 onto the surface of the rotor 4 before the slot 5 or when the product 34 is held up on the edge of the slot 5 In this case, the lower shoulder 18 of the shutter 16 comes into contact with the lower part of the socket 5, whereby the upper shoulder 17 deflects in the direction of movement of the socket 5, accompanying it.

Upon further movement of the nest 5 with the product 34, the air distributor 33 directs the flow of compressed air through the air duct 31 to the openings 29, the product 34 "floats in the air flow and when the air supply stops, it goes down into the nest 5 with a heavier part and thus before processing.

In the next section along the rotation of the rotor 4, the rollers 8, which are located in the grooves of the cylindrical cams 3, cause shifting towards the products 34 of the working parts with cutting tools 7, which, thanks to paragraph 23, are mounted on spindles 6 and associated with the pulleys 22 on the camshaft 21, are in constant rotation.

Upon completion of the machining of the products 34, the rotor occurs during the movement of the rotor 4, the rollers 8 remove the working parts with cutting tools 7 from the products 6. Compressed air is supplied through the duct 31 to the aperture 29. Item 6 reappears, but it is no longer lowered into the nest 5, and is blown off to the side by a stream of compressed air supplied to the openings 30 through duct 32, and enters the collection of processed products.
