According to the scheme, the requirement of carrying outprimary crushing on large woven bag raw materials is met, and the woven bag raw material primary crushing device is most applied to a woven bag machining assembly line.

The invention discloses a two-way rotatable involute tooth profile internal meshing gear pump, which belongs to the technical field of hydraulic transmission. The involute tooth profile is accurately realized through the symmetrical arrangement of a crescent plate, a ring gear and a gear in a seat hole. The two-way rotation of the internal gear pump improves the functionality and scope of application of the involute tooth profile internal gear pump; and through the "displacement" setting of the ring gear in the seat hole and the corresponding setting of the seat plate in the seat hole, it can Effectively avoid the interaction between the ring gear and the inner wall of the seat hole due to the radial load generated by the rotation. The bidirectionally rotatable involute tooth profile internal meshing gear pump of the present invention has a compact structure and is easy to install, and can accurately realize the bidirectional rotation of the involute tooth profile internal meshing gear pump, avoiding the outer periphery of the ring gear and the inner peripheral wall of the seat hole. The wear and tear of the internal meshing gear pump prolongs the service life of the components in the internal meshing gear pump, improves the comprehensive performance of the internal meshing gear pump, and has a good application prospect and promotion value.

The invention relates to the field of tire forming, in particular to a tire body of a tire forming capsule and a preparing method of the capsule body. The capsule body of the tire forming capsule comprises an outer capsule body, a first reversely-wrapped capsule body and a second reversely-wrapped capsule body, all of which are integrally formed in a vulcanization manner. The first reversely-wrapped capsule body and the second reversely-wrapped capsule body are connected with the two ends of the outer capsule body correspondingly and are folded back to be reversely wrapped. When the capsule body is formed in the vulcanization manner, the outer surface of the outer capsule body, the outer surface of the first reversely-wrapped capsule body and the outer surface of the second reversely-wrapped capsule body are attached to a die, the inner surface of the outer capsule body, the inner surface of the first reversely-wrapped capsule body and the inner surface of the second reversely-wrapped capsule body are inflated by 2 bar-10 bar, the vulcanization time ranges from 30 min to 120 min, and the temperature ranges from 120 DEG C to 180 DEG C. The flatness of the surface of the capsule body can be ensured through control over the smoothness of a die housing, and uniformity of the thickness of the capsule body is mainly affected by fluctuation of the thickness of semi-finished rubber sheets under the condition that the size and the inflation inner pressure of a die cavity are stable.

The present invention is an asynchronous frequency division circuit with self-refresh function and anti-single event reversal effect, which includes a majority voting circuit and a parallel three-stage counting frequency division module, and the counting frequency division module includes a frequency division number configuration circuit and a counter circuit. The use of redundant structure, majority voting circuit and self-refresh method greatly improves the anti-single event flipping effect of the asynchronous frequency division circuit; the single event flipping event in a single frequency division circuit is suppressed through redundant voting, and the output frequency is output after utilizing the majority voting The signal performs real-time refresh control on the three counting frequency division modules to ensure that the three counting frequency division modules work in the same state, eliminating the accumulation of timing error states caused by the single event flip effect in the counting frequency division module, and greatly reducing the asynchronous frequency division circuit. The single event flip probability improves the reliability of integrated circuits in space application environments.
