The invention relates to a tool (11a, 11b, 11c) for pressing a multilayer press packet (1b), particularly for placing inside a press (2), preferably for inserting into the insertion opening (3) of a multiplaten press (2a). The multilayer press packet (1b), in particular, has a number of multilayers (7) that are separated from one another by at least one separating plate (6). Advantages are achieved by virtue of the fact that the tool (11, 11b, 11c) can be electrically heated. To this end, at least one electrically operable heating element (10) is provided.

The invention relates to a scarf rope twisting and knot tying machine and a rope twisting and knot tying method, wherein the scarf rope twisting and knot tying machine can automatically twist weft yarns reserved in a scarf into even and unified rope-shaped tassels in a strand-split mode, cut off the yarns and tie off. The scarf rope twisting and knot tying machine comprises a machine frame, a positioning device, a rope twisting device and a knot tying machine. The machine frame comprises a bottom beam and a middle beam, a bush-hook groove vertically penetrates through the middle of the bottom beam, lifting arrangement type bush-hooks are arranged in the bush-hook groove in the middle of the bottom beam, a lower twisting plate is arranged on the bottom beam of the machine frame, slide ways are arranged on the left side and the right side of the bottom beam, and the knot tying machine is installed in a middle cross beam of the machine frame. The scarf rope twisting and knot tying machine and the rope twisting and knot tying method have the advantages of 1 being capable of automatically fishing work that the weft yarns reserved in the scarf are twisted into ropes and tied off, greatly saving producing and processing time and simultaneously reducing work amount of workers, and 2 very uniformly performing rope twisting and knot tying work and enabling produced tassels to be even in thickness, delicate in appearance and perfect and ideal in effect.

The invention provides a method for synthesizing tributyl citrate (TBC) by adopting a composite ionic liquid catalyst. The method is characterized by comprising the following steps: firstly carrying out esterification on taking citric acid and n-butyl alcohol which serve as raw materials in the presence of the catalyst, after esterification is qualified, directly utilizing the waste heat to reduce pressure and eliminate alcohol in a reaction kettle to obtain a crude product of tributyl citrate containing the catalyst, then carrying out acetylation and finally carrying out deacidification, standing, cooling, catalyst separation, neutralization, washing and reduced pressure distillation, thus obtaining the colorless transparent liquid TBC without decoloration and pressure filtration. The method has the following advantages: the same amount of the same catalyst is used in esterification and acetylation, thus realizing reuse of the catalyst; the conversion rate is high, the by-products are few and the yield is more than 98%; aftertreatment is simple and convenient, excessive alkaline water for neutralization and washing is not needed, the washing clear water can be reused and no pollutants are discharged; and the reaction temperature is low, the production period is short, the equipment investment is low, the energy consumption is low, and the cost is low.

The invention discloses a waste rubber crawler belt material recycling production line. The waste rubber crawler belt material recycling production line comprises a segmenting and cutting-off tool, asurface rough cutting tool, a surface treatment and separation device, a reclaimed material conveying structure and a vacuum recycling device; the segmenting and cutting-off tool is used for segmenting and cutting off a crawler belt; the surface rough cutting tool is used for carrying out rough cutting treatment on cut-off long-strip-shaped crawler belt surface rubber; the surface treatment and separation device is used for carrying out cutting treatment, embedded part separation, steel wire separation and steel wire shearing short and recycling on the roughly cut crawler belt remaining surface layer rubber; the reclaimed material conveying structure is used for conveying the cut surface rubber and an embedded part; and the vacuum recycling device is used for carrying out vacuum collectionand recycling on rubber particles left by the rough cutting treatment. According to the waste rubber crawler belt material recycling production line, residual rubber scraping, embedded part separation and steel wire shearing short and collection of the waste rubber crawler belt can be realized, the functions of the equipment are various, the classification and collection of all components in thewaste rubber crawler belt are effectively realized, the working synergy of all the mechanisms in the equipment is high, and the working efficiency is high.
