Displacement adjustment device for separating knife on spinning preparation machine and its application method

Abstract

The invention discloses a separation knife position change adjusting device of a spinning preparation machine and a use method thereof. The separation knife position change adjusting device comprises a separation roll, a separation knife body, a rotating knife rest, a dust receiving barrel, a rolling shaft, a rolling plate and an automatic rolling mechanism, wherein the separation knife body is mounted on the rotating knife rest which can move along the periphery of the separation roll; the knife tip of the separation knife body is tangent with the excircle of the separation roll; the dust receiving barrel is mounted on the rotating knife rest; one end of the rolling plate is fixed to the opening end of the dust receiving barrel; one end of the rolling late is connected with the automatic rolling mechanism; the rolling shaft is arranged between the dust receiving barrel and the rolling mechanism and is in contact with the outer side face of the rolling plate. Compared with the prior art, the separation knife position change adjusting device has the advantages that the structure is simpler, the friction resistance is small, the sealing performance is good, the separation knife position change adjustment is convenient, the use is reliable, the effect is good, the cost is low, and the maintenance is convenient.

Description

Technical field: [0001] The present invention relates to spinning preparation equipment, for example, carding machine, blowing machine, opening and dedusting machine or similar machinery, especially relates to the separating knife displacement adjustment device therein. Background technique: [0002] Federal Germany's Trufischer Co., Ltd. and KGG disclosed a "device with at least one separating knife on the spinning preparation machine" in the patent No. 03142594.1, and its core technical solution is: the separating knife wherein 17 is installed on a support member 20, and this support member 20 can move parallel to the circumference of described roller 30, to adjust the distance between separating knife 17 and described fixed position relatively fixed element 19, is installed on support member 20 A discharge chamber 18, which cooperates with a first arc-shaped leading edge fixed on the fixed element 19, which is arranged to be in a fixed position during operation of the mac...

Problems solved by technology

[0003] ① Although this structure can adjust the separation knife to move circumferentially along the corresponding roller to adjust the distance between the separation knife 17 and the fiber separation point, it can guide the separated impurities F and / or air E to the opening of the discharge chamber 18 In G, however, the track between the discharge chamber 18 and the fixed element 19 can be formed by the cooperation of the arc surface to facilitate the inflow of impurities and or air, but there must be a gap between the two, if the gap is too small, the movement between the two The friction resistance increases, and in serious cases, it will cause jamming. If the gap is too large and not sealed, it will cause air leakage, which will affect the effect of impurity removal and exhaust.

[0004] ② The structures of the fixing element 19 and the discharge chamber 18 are complicated, the manufacturing precision is high, the difficulty is high, the cost is high, and the maintenance is difficult
