Abstract

The invention relates to stone processing equipment and is intended for calibrating and grinding facing tiles, bars, planks and various types of stone. The invention improves the quality of processing by reducing the dynamic loads on the end of the abrasive wheel and increasing the rigidity of the system, which is ensured by the fact that table 17 fixed under the cargo branch 3 is rigidly fixed to the portal 9 grinding units 7 and 8 and has the ability to synchronously move with branch 3 from the reciprocating actuator 24, and perpendicular to the longitudinal axis of the conveyor 1 on both sides of the abrasive wheel 16 are located clamping strips 18, connected by hinges 1 9 with rocker arms 20, on which Some of them are secured by rods interacting with clamping mechanisms 22. 2 Il. i 1 (l 35 CO ate NP 4 M 17 Fig.1 22 2b 2 25 5

Description

f1

The invention relates to stone processing equipment for the industry of building materials and is intended for calibrating and grinding facing parts — plates, bars, planks of various types of stone.

The purpose of the Invention is to improve the quality and productivity of grinding of hard rock slabs due to increasing the rigidity of the system tool - part - load branch, and reducing the dynamic loads on the tool end,

Fig. 1 shows a device for processing stone, side view: Fig. 2 is section A-A in Fig. 1.

The device consists of a belt conveyor 1 with a drive 2 and a cargo branch 3. With plates 4, a guide roller table 5, support guides 6, two grinders 7 and 8, each of which has a portal 9, a ball 10, a carriage 11 with a drive 12, gearbox 13 gears, V-belt gearing 14, spindle 15 and abrasive ™ wheel 16, table 17, pressure plates 18, hinges 19, rocker arms 20, bar 21, clip mechanisms 22, bracket 23, reciprocating drive 24 and support 25,

The device works as follows.

The actuator 12 is turned on, which, through the gearbox 13 and the clinorem transmission 14, rotates the spindle 15 with an abrasive wheel 16 mounted on it and then the drive 2 of the conveyor 1, on which the plates 4 placed on the load branch are pressed by the guide roller 5 to the conveyor belt and served in the processing zone of the grinding unit 7. When the edge of the plate 4 enters the processing zone, the control system (not shown) activates a reciprocating actuator 24 mounted on the support 25 and hinged to the bracket 23 of the table 17 ,, which moves and moves the gantry 9 at the feed rate of the load branch 3 of the conveyor 1. At this moment, the clamping mechanisms 22 are triggered by the yokes 21 of the rocker arms 20 connected by hinges 19 to the clamping strips 18, lowered from the upper position, pressed down with a certain force and fixed on the plate 4 and the cargo branch 3 on the table 17, then karet72

When 11, at its extreme position, begins to move along beam 10 at a feed rate, and abrasive wheel 16 cuts into the slab. Plate 4, performing a continuous feed motion

conveyor 1, can not affect the end of the tool in the grinding process, as the plate 4, cargo branch 3, table 17, portal 9

and beam 10 is a single rigid system, which excludes dynamic loads on the end of the abrasive wheel 16 and intensive wear of the cutting surface at the ends,

Circle 16 handles the slab with the entire width of the cutting surface, sliding 1. with a uniform thickness across the entire width of the plate, and when it comes out of contact with it, mechanisms 22 are clamped and lift the presser bars 18 to the upper position, the carriage 11 stops in its extreme position . At this point, the reverse of the reciprocating

the drive 24 and the portal 9 returns to the initial position; the drive 24 turns off - the cycle is over. In the initial position, the portal 9 is until the moment when the load branch 3 moves from the position in which the control system included the drive 24, by an amount equal to a given width of processing in one pass of the abrasive wheel 16, which, as a rule,

close to the width of the circle. After that, the cycle repeats. The plate 4 processed by the grinding unit 7 is fed to the processing zone of the grinding unit 8J, in which the carriage 11 with an abrasive wheel 16 is installed above the table 17 in a position where the distance between the surface of the cargo branch 3 of the conveyor belt and the driving surface of the wheel 16 is equal to the required

to the size of the thickness of the processed plate, almost half of the stock is cut off by the node 7, the rest of the stock (2.0-2.5 mm) is cut off by the node 8. Machines processed by the node 8 are removed from conveyor 1 to the roller table and further to the following operations,

formula of invention

A stone processing device containing a conveyor with a cargo branch, a guide roller table and grinding units, each of which

mounted with the possibility of movement along the conveyor and made in the form of a portal with a beam located perpendicular to the longitudinal axis of the conveyor, and mounted on it with the possibility of moving along the beam of the carriage bearing the spindle of the tool. In that, in order to improve quality and processing performance

15247. four

it is equipped with a table rigidly fixed on the portal under the cargo; a branch, and a part clamping mechanism, made in the form of two clamping plates located across the cargo branch, the ends of which are articulated by rocker arms, connected via rods with clamping elements 10 fixed on the table on both sides of the cargo branch.
