Description

Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to a steel belt crusher. Background Art

[0002] In the prior art, such as Figures 1 to 3 As shown, the steel strip cooling forming machine basically adopts a double spiral shaft crusher. Its working principle is to send the continuous thin slices (thin slices are generally 1~5mm thick and 100~1850mm wide) after the steel strip is cooled and solidified into the crusher. The crusher first uses the upper pre-crushing shaft 21 to break it into large pieces of ~100*100mm (palm size), and then enters the lower double spiral shaft for further crushing. The double shafts rotate in opposite directions. The comb plate 22 with a notch and the blade on the crushing shaft 1 shear each other, thereby further breaking the thin slices. The size of the final product depends on the matching size of the notch on the comb plate 22 and the blade on the crushing shaft 1. Generally, the final size after crushing is 8*8mm, which directly enters the downstream packaging. The double shafts are driven by two gears 3 with the same pitch circle, and their speeds are the same. For low-yield occasions, one spiral crushing shaft 1 and comb plate 22 can be reduced to reduce costs.

[0003] Some problems were found in the use and processing of the existing double screw shaft crusher:

[0004] 1. During on-site use, the comb plate 22 is subjected to long-term impact, and the metal material is prone to fatigue. If it breaks, it will enter the downstream packaging. If it cannot be discovered in time, it will cause serious problems to the user of the broken product.

[0005] Second, the gap between the opening of the comb plate 22 and the blade on the crushing shaft 1 is very small, generally 0.5~1mm. If a hard object such as a bolt falls into the crushing chamber, the crusher will be directly stuck. If it is not discovered in time, the motor is prone to damage.

[0006] 3. Although the spiral structure is used, the opening of the blade and the comb plate 22 work at 1~2 positions at the moment of crushing, that is, the point working mode. However, the noise is still very loud during crushing. When crushing hard materials, the noise of the crusher is 80~100 decibels at 1 meter. It is easy to cause hearing damage to operators in the long term and cause occupational diseases. Summary of the invention

[0038] Specifically, Figures 4 to 8 As shown, in this embodiment, the crushing shaft 1 is rotatably arranged on the frame 4, and the two crushing shafts 1 are arranged in parallel in the discharge port 41. The two crushing shafts 1 rotate relative to each other to extrude the steel belt, and the previous shearing mode of the blade and the comb plate 22 on the shaft is changed to a mutual extrusion shearing mode in which the two shafts rotate toward the center at the same time, which can adapt to the crushing of various flaky products, significantly reduce the use noise, and save the upstream pre-crushing shaft 21; two gears 3 are respectively arranged on the two crushing shafts 1, and the two gears 3 are meshed with each other; the driving member is fixed on the frame 4 and connected to one of the crushing shafts 1, driving one of the crushing shafts 1 to rotate, thereby driving the other crushing shaft 1 to rotate in the opposite direction, and the driving member can be a servo motor to accurately control the rotation of the crushing shaft 1, and realize transmission through the meshing of the two gears 3.

[0039] Further, if Figures 5 to 8 As shown, in this embodiment, the crushing shaft 1 includes: a rotating shaft 11, the rotating shaft 11 is rotatably set on the frame 4, and the gear 3 is fixed at one end of the rotating shaft 11; a plurality of toothed grooves 12, and the plurality of toothed grooves 12 are opened along the length direction of the rotating shaft 11 to form a knife-edge shape to crush the steel strip, and the toothed grooves 12 are provided with a deflection angle along the axial direction, and a plurality of toothed grooves 12 are ratchet-shaped. In this embodiment, the two gears 3 have different numbers of teeth, and the two crushing shafts 1 have a speed difference when rotating, and the size of the steel strip after crushing will also be different. The size of the steel strip after crushing can be changed by adjusting the deflection angle and the number of teeth of the gear 3. Due to the different numbers of teeth of the gear 3, the two crushing shafts 1 have a speed difference, forming a Figure 6 The toothed grooves 12 on the outer surfaces of the two crushing shafts 1 shown in the figure form a network shear crushing form at the central extrusion point.

[0040] Specifically, Figure 7-8As shown, in this embodiment, it also includes: an adjusting mechanism 5, an adjusting mechanism 5, the adjusting mechanism 5 is fixed on the frame 4 and connected to one of the crushing shafts 1, the adjusting mechanism 5 adjusts the distance between the two crushing shafts 1, adapts to different working conditions and materials, and achieves different shearing effects on the steel strip. In this embodiment, the adjustment mechanism 5 includes: a connecting rod 51, which passes through the two side plates 42 of the frame 4, and the number of the connecting rods 51 is a pair, which are respectively arranged at the two ends of the crushing shaft 1, one end of the connecting rod 51 is rotatably connected to one of the crushing shafts 1, and the opening of the connecting rod 51 can be sleeved on the crushing shaft 1 through the form of an opening, which does not affect the rotation of the crushing shaft 1, and the other end can be telescopically arranged on the frame 4 to achieve the position adjustment of the crushing shaft 1; a limiting nut 52, which is screwed on the connecting rod 51, and the limiting nut 52 is arranged between the two side plates 42, and the limiting nut 52 abuts against the side plate 42 close to the crushing shaft 1 to limit the farthest distance between the two crushing shafts 1; an adjusting member, which is connected to the connecting rod 51, and adjusts one of the crushing shafts 1 to be close to or away from the other crushing shaft 1, that is, adjusts the gap between the two crushing shafts 1. By adding the adjustment mechanism 5, the overall flexibility and applicability of the device are improved, and the mechanism is simple, convenient and fast.

[0041] Further, if Figure 7 As shown, in this embodiment, the adjusting member includes: a pressure-adjusting nut 53 and a spring 54; the pressure-adjusting nut 53 is screwed on the connecting rod 51, and the pressure-adjusting nut 53 is arranged between the two side plates 42; the spring 54 is sleeved on the connecting rod 51, and the two ends of the spring 54 are respectively abutted against the pressure-adjusting nut 53 and the side plate 42 away from the crushing shaft 1; the pressure-adjusting nut 53 adjusts the pressing force of the spring 54, and the spring 54 can automatically compensate for the distance between the two crushing shafts 1. When a large amount of products or foreign matter enters between the two crushing shafts 1, the crushing shaft 1 connected to the connecting rod 51 will compress the spring 54, and automatically adjust the distance between the two crushing shafts 1 to avoid stalling and damage to mechanical equipment.

[0042] Further, if Figure 8 As shown, in this embodiment, the adjusting member includes: a cylinder 55, which is fixed on the frame 4 and connected to the other end of the connecting rod 51.
