Description

The invention relates to the equipment of the rubber industry, in particular to devices for the roughing of blanks of sheet elastic materials, for example, rubber boat blanks. A device for roughing sheet blanks from elastic materials containing a frame with a base plate and a scouring tool in the form of a drive endless abrasive belt Cl is known.

This device allows the blanks to be roughened only by rectangular sections, and therefore has limited use.

The closest to the proposed device is a device for roughing blanks from sheet elastic materials, containing driving roughing tools mounted on a frame rotatably in opposite directions, supporting a blank element with a template mounted on it, and pressure units 2 which move in a vertical direction.

Such a device is structurally difficult, is designed for roughing blanks of the same profile and size along their perimeters and areas within their contours, and is not suitable without readjusting for roughing blanks of other profiles and sizes with other geometric shapes and the location of roughing areas within their contours. . .

In addition, this device is not designed for continuous roughing of blanks and is not productive enough because of the need for roughing around their contours with their movement to the extreme positions on the base plate-up to the stops when disconnecting the conveyor belts with emery cloths, the speed of movement of which is limited and cannot to ensure a sufficient roughing speed (grinding speed equal to 30 m / s), therefore, the required amount of roughing is achieved by increasing the dwell time of blanks on roughing trays nspors.

The aim of the invention is to increase productivity and ease of operation.

This is achieved by a device for roughing blanks of sheet elastic materials, containing driving rough tools mounted on the frame rotatably in opposite directions, supporting the blank element with a template mounted, and vertical clamping units, according to the invention, are provided with two pairs of pulling rollers, and the billet-supporting element is designed as a driving belt conveyor, the upper branch of which 5 is located between the last, while the pressure nodes are made in the form of vertical pushers mounted under the conveyor with rollers at the ends and kinematically connected

10 with a belt conveyor drive of profile cams interacting with the lower rollers of the pushers, with the grinding tools mounted above the belt

5 by a conveyor between the pairs of pulling rollers, and the template is made of elastic material.

FIG. 1. schematically depicts the proposed device, the type of SpecQ Redi; in fig. 2 - the same, view reconciliation; in fig. 3 shows a section A-A in FIG. in fig. 4 shows a section BB in FIG. 2; in fig. 5,6-sequence roughing areas of the workpieces.

The device for roughing blanks from sheet elastic materials contains a frame 1 on which are mounted rotating tools 2 and 3 rotating in opposite directions, templates 4 with elastic sponge rubber 5 glued to them, made according to the shape and dimensions of the rough sections of blanks 6, and drives 7 tools 2 and 3.

5 Templates 4 are made of elastic material, for example, of multilayered duplicated rubberized fabric, and fixed on the belt conveyor 8 by means of fasteners 9, for example, push-button. The upper branch of the conveyor 8 is located between two pairs of dragging rollers 10 and 11, on the shafts of which gears 12 and 13 are attached to each other. The support rollers 10 are also equipped with sprockets 14, 15 and 16 fixed to their shafts, connected by chain drives 17 and 18 , and an asterisk 19 mounted on the drive shaft 20

 the drum 21 of the conveyor 8,

Tools 2 and 3 are made in the form of drums, on which abrasive belts 22 are attached, and are connected by V-belt drives 23 with drives 7, which cause them to rotate in opposite directions.

Tools 2 and 3 are mounted above the conveyor 8, under which the clamping units are installed in the form

0 vertical pushers 24 with upper rollers 25 and lower rollers 26. Pushers 24 are located in rails 27. Rollers 26 interact with profile cams 28. The latter are fixed on horizontal

shafts 29, equipped with sprockets 30 and 31, connected by chain gears 32 and 33 between themselves and with the drum 21 of the conveyor 8..

Drive gear 8 and rollers

10 and 11 from the electric motor 34 with the pneumatic friction clutch 35 and the gearbox 36, connected by chain drives 37, 17 and 18 to the drum 21 of the Transporter 8. And carrying a roller 10 and 11.

The clutch 35 is controlled from a spring-loaded pedal 38 with ring switches 39 connected to the switching valve solenoid valve 40, through which compressed air from the network enters the cavities of this clutch.

The device works as follows.

Include motors for conveyor drives B, rollers 10 and

11 and tools 2 and 3.

When the template 4 approaches the right pair of rollers Yu and 11, the pedal 38 is pressed, the compressed air from the network through the air distributor 40 disconnects the clutch 35 of the operating electric motor 34, and the conveyor 8 and the rollers 10, 11 stop. Take the workpiece 6 and put it on the template 4, the orientation of its edges on the elements 5. Then remove the force from the spring-loaded pedal 38 and the compressed air from the network through the air distributor 40 turns on the coupling 35 of the electric motor 34, which moves the conveyor 8 with the workpiece b lying on the template 4 first, up to the rollers 10 and 11 rotating along the movement of the conveyor 8 with the same speed. When the template 4 approaches the workpiece b, the tool 3 moves to the rotating tool 8

the right support roller 25 under the influence of the pushers 24 and the cam 28 is consistently raised to the upper position and when the workpiece b passes in the gap between the tool 3 and the roller 25, continuous roughing of its sections on the elements 5 occurs (Fig. 5). At the same time, the left roller 25 under the influence of the left pairs of pushers 24 and cams 28 is in the lower position and the workpiece b, when it is grooved around the perimeter and inside its contours, freely passes in the gap between the tool 2 and the roller 25 and the left a pair of rollers 10 and 11, also rotating in the direction of the conveyor 8 and at the same speed T9. At this point, the cams 28 are aligned from, drive the right roller 25 to the bottom attachment, and the left roller 25 to the upper position. The latter presses the conveyor 8 with the template 4 and the workpiece 6 to the rotating towards the movement of the conveyor 8. Tool 2 (Fig. 2), which continuously roughs the remaining parts of the workpiece b held from being pulled out by the left pair of rollers 10 and 11. When the workpiece b leaves the tool area

0

2 and the roller 25, the process of its roughing ends (Fig. &Amp;), and it moves further along the conveyor 8 and enters the storage cart (not shown in the figures). At this time, to the right riape of the rollers 10 and 11

5, the next pattern 4 fits onto which the next billet is laid, and, thus, a continuous roughing of the blanks is carried out at the same time according to their dimensions and

0 areas inside their contours,

. The rotation of tools 2 and 3 in different directions is necessary and moreover, such as shown in FIG. 1 (with

5 movement of conveyor belts with processed. from right to left), since when the front (left) part of the workpiece b is roughened (Fig. 5), it is captured by rotating

0 move her tool

3and is kept when the right pair of rollers 10, 11 is being further scorched and further when the workpiece b is adjusted on the conveyor 8 in the gap

5 left pair of rollers 10 and 11 (when raised to the upper position the left roller 25 and 1 is retracted to the lower position the right roller 25) the tool 2 rotates against the movement of the workpiece pulled by the left pair

0 rollers 10 and 11, coats the rear (right) part of the workpiece

b (Fig. 6).

Only with such a rotation in different directions of the grinding tools

It is possible to continuously rough the parts of the workpieces moving on the conveyor belt under rotating curving tools.

The use of roughing tools in the form of drums with an abrasive tape attached to them makes it possible to increase the speed of the roughing of the rollers. In addition, this device design provides continuous,

5 productive, and high-quality woodwork of various designs and sizes of blanks. The device is simple in construction, convenient to. operation, transfer to the roughing of the workpiece of another type, measure is carried out by replacing the template. .

Labor productivity increases in za times.
