Abstract

The invention relates to the building materials industry and can be used in the manufacture of ceramic wall materials. The purpose of the invention is to increase the operational reliability of the device by eliminating the repeated activation of the cutting mechanism. The device contains a belt conveyor 1 with a finger disc 10, a carriage 8 with a single-string onion 9. The synchronization mechanism in the form of a gear 3, cam 4, lever 5, ti 6 and leash 7 converts the rotation of the drum of the belt conveyor 1 into the reciprocating movement of the carriage 8 for moving a single-string beam 9 synchronously with the incoming beam. The cutting mechanism in the form of a crank drive gear 19 and a shaft 24 with a friction clutch 22 informs the single-stalk beam 9 a swinging movement from a drive consisting of an engine 27, a belt drive 26 and a gear train 25. The shift mechanism includes a cam clutch on the shaft 24 of the friction clutch 22, which is articulated a three-link 15 with a movable axis 30, a disk copier 13 with a lever 12 and a two-arm lever 11, one arm of which is in contact with a finger disk 10, and the other connected with the lever 12 of a disk copier 13. The switching mechanism is equipped with a cam 32 mounted on the shaft 24, and the double shoulders lever 11 is a deviating hitch made in the form of a spring-loaded platform 16 pivotally mounted on it with an adjustable stop 17. When pressing the finger disc 10 on the double-shouldered lever 11, the adjustable stop 17 by the pressure surface rotates the lever 12 of the disk copy 13, which by means of three-sided hinge 15 includes a cam clutch and the shaft 24 is rotated, together with a single-string onion 9, an oscillatory motion. 1 hp f-ly, 4 ill.

The invention relates to the building materials industry and can be used in the manufacture of ceramic products. The purpose of the invention is to improve the operational reliability of the device by eliminating the repeated activation of the cutting mechanism.

FIG. 1 shows a kinematic diagram of the device; in fig. 2 shows section A-A in FIG. one; on fig.Z - section bb in fig. one; figure 4 - section bb In fig. one.

The device contains a belt conveyor 1 with a leading drum 2. The synchronization mechanism in the form of a gear 3, cam 4, lever 5, rod 6 and driver 7 serves to convert the rotation of the drum of the belt conveyor 1 into a reciprocating movement of the carriage 8 with the beam 9 synchronized with the speed of movement of the clay bar.

The finger disk U attached to the gear wheel 3 contacts the two-arm lever 11 of the shift mechanism. The other shoulder of the two shoulders lever 11 interacts with the lever 12 of the disk copy machine 13 in contact with the axis 14 of the three-hinged link 15. On the two shoulders of the lever 17, the mount 1 is deflected a deflecting hook, made in the form of a spring-loaded platform 16 with an adjustable stop 17. The deflecting platform hook hooked spring 18 holding the surface of the adjustable stop 17 to the lever 12 of the disk copy 13.

When pressing the finger disc 10 on the double-arm lever 11, the adjustable stop 17 by the pressure surface rotates the lever 12 of the disk copier 13, which by means of the three-link articulated 15 engages a cam clutch and the shaft 24 is rotated, together with a single-string beam 9, an oscillatory motion. 1 z.p, f-ly, 4 silt,

The device also contains a cutting mechanism in the form of a crank drive gear 19 connected to the shaft of a single-string beam .9. The coupling halves 20 and 21 of the cam clutch, the clutch 22 with the spring 23 are designed to transmit rotation — from the shaft 24 to the shaft of the crank gear 19. The shaft 24 of the clutch 22 receives rotation from the drive consisting of a gear 25, a belt drive 26 and an engine 27. For a quick stop of the shaft 24, by means of the clutch 22, a locking disk 28 with a spring is designed. 29. On the half-coupling 21 of the switching mechanism, the movable axis 30 of the three-link articulator 15 is installed, the axis 14 of which is pressed by the spring 31 to the disk copy machine 13. The switching mechanism is equipped with a cam 32 mounted on the shaft 24 with the ability to interact with the pressure surface of the spring-loaded platform 16 of the deviating hook . All mechanisms of the device are located on the frame 33.

The device works as follows. , ,

Through a belt drive 26, the motor continuously reports rotation to the gear train 25, the wheel of which is freely seated on. shaft 24. A clay bar sets the belt conveyor 1 in motion, the leading drum 2 of which, by means of a synchronization mechanism, drives the carriage 8 with the beam 9 in a reciprocating movement. At the same time, the finger of the switching mechanism 10 acts on a double-arm lever

eleven . When the two shoulders lever 11 deviates from its position, the adjustable stop 17 rotates the lever 12 of the disk copier 13, which, affecting the axis 14 of the three-link hinge 15, moves the movable axis 30. As a result, the coupling half 21 is displaced, and the friction clutch 22 under the action

the spring 23 is pressed against the surface of the gear wheel 25, the rotation of which is transmitted to the clutch 22 and the shaft 24.

The rotation of the shaft 24 is converted by the crank drive gear 19 into an oscillating motion of the beam 9. At the initial moment of rotation of the shaft 24, the cam 32 mounted on it deflects the spring-loaded pad 16, acting on its pressure surface. At the same time, step 12 jumps off the retaining surface of the adjustable stop 17, which after passage of the cam 32 returns the spring 18 to its original position, i.e. comes into contact with its holding surface with the lever 12 returned to its original position by the spring 31.

The camshaft coupling half 20, having made one revolution with the shaft 24, runs its protrusion onto the projection of the coupling half 21, which pushes the frictions. it is in the direction of the locking disk 28. The clutch 24 of the clutch 22 stops rotation and the bow 9 stops in the extreme position.

A new cycle of oscillatory onion movement can occur only when the finger of the finger disc 10 - releases the double-arm lever 11, which, together with the spring deviating from the hook, is removed 18. When lowering the deflection hook,

the adjustable stop 17 is lowered with its holding surface below the disk copy arm lever 12 13. Further, when the finger of the finger 10 is pressed on the double-arm lever 11, the cutting cycle is repeated in the same sequence.
