SU32459A1 - Automatic Belt Press Cutting Machine - Google Patents

Description

In the proposed automatic belt press cutter, the knife mounted on the tail of the yoke cuts the clay tape during its fall from the extreme position into which it is led by a steerable fist. The latter acts on a spring-loaded slider, which is connected by an earring with a knife-carrying collar. When idling (lifting), the knife is moved away with the help of connecting rods and an eccentric from the clay tape, the entrance to the cleaning box.

In the modified apparatus, instead of a knife, a wire beam is used, lowering and lifting it is made by cams acting on the tail of the yoke and connected with a spring-loaded slide, moving up and down under the action of a latching fist. The collar is provided with a counterweight and is held in extreme positions by a balance bar.

In FIG. Figure 1 shows schematically a belt press with the proposed cutting apparatus and a conveyor which takes the clay cut into pieces; FIG. cutting apparatus front; FIG. 3-section on AB in FIG. 2; FIG. 4-view of the apparatus from the back; FIG. 5 is a front view of a modified apparatus; FIG. 6 - section

The EF software in FIG. five; FIG. 7 shows a CD section of FIG. five.

A shaft 5 of a belt press / press is passed through the bed 7 of the cutting machine, on which a collar / Р with a tail 22 (Fig. 2 and 3) carrying the knife 25 is mounted on the sleeve. The collar J9 is connected with an earring 75 with a slide J4 clamped by a spring 77 to the fist 2 via the roller 75 (fit. 4), rolled over it. The cam J2 is mounted on the JO shaft, which is rotated from the press shaft 5 by means of gears 8, 7 and 13 located on the other side of the bed 7 than the collar 19. On the same shaft 10 an eccentric 77 with a connecting rod 20 articulated with a slide block 21 / (Fig. ° 2) moving along the tail 22 of the collar and fastened to the knife 23.

When the shaft 10 rotates, the cam 12 lifts the slider 14 and the collar 19 associated with the earring 18, while the eccentric 77 and the connecting rod 20 move the tail 22 with the knife 23 away from the clay tape coming out of the mouthpiece 19 of the press (Fig. 1). on its way passes through the cleaning box 24 (Fig. 2). When it reaches the topmost position, the clamp stops and holds in this position during the half-turn of the shaft 10, and the crank 77 pushes the blade 23 at this time.

Further rotation of the shaft 10, the roller / 5 of the slider / jumps off the ledge of the knuckle / 2, as a result of which the clamp 19 with the knife 2B falls and the latter cuts the clay tape. In the lower position, the clamp is at rest during the rotation / turn of the shaft 10, and the knife 23 this time interval will move away from the clay tape. The next V4 turn of the shaft 70. The yoke will begin to rise, and the knife will take an extreme pushed position, then the cycle of movements of the yoke and knife will be repeated. In order to mitigate the impact of the yoke, the latter is equipped with a rubber shock absorber 26. To change the length of the cut part of the clay tape, the interchangeable gear / 3 is rearranged.

The cut pieces of clay tape are fed to the belt conveyor / b (Fig. 1), which receives movement by means of a belt drive / 4 and conical gear 73 from the shaft fO.

In order to access the mouthpiece 79, the device is mounted with a rotating pivot about the shaft 5;

Attached to the conveyor plate 78, the purpose of which is to prevent bending of the knife 23.

In the embodiment shown in FIG. 5-7 of the modified apparatus, instead of a knife, on the end of the clamping shaft 79 on the shaft 5, the wire beam 5 is reinforced. The clamp 79 by the counterweight 33 and the balance bar 32 is held in the upper and lower end positions. Raising and lowering the clamp / 9 with onion 34 is

also from the tilting fist 72, raising and lowering the spring-loaded sliders 74, associated with Kyj; ia4kami 37; last hit on collar f9.

The subject matter of the invention.

Claims (4)

1. An automatic belt press cutting machine, characterized in that in order to quickly cross the clay press from the mouthpiece 79 of the clay press, the flat knife 23 is movable, using a slider 27, mounted on the tail 22 of the yoke 79, connected with spring-loaded earrings 78 the slider 74, cocked into the shock position of the conical fist 72 (Fig. 1-4). 2. The form of the apparatus according to claim 1, characterized in that in order to move the knife away from the clay during idling, the slider 2 / knife 23, by means of a connecting rod 20 is articulated with an eccentric 77 mounted on a common shaft 70 with a cam 72 clamp 79 (Fig. 2-3). 3. A machine change according to claim 1, characterized in that instead of a knife a wire beam 34 is used, lifted and lowered by strikes of cams 37 associated with spring-loaded sliders 74, cocked and lowered up and down by a tandem fist 72 (Fig. 5-7) . 4. In the apparatus of claim 3, use the balancer 32 to hold the onion in extreme positions (Fig. 5).
