Abstract
The utility model relates to a kind of cutters for PET staple fiber re-use device, it is characterized in that: what include upper and lower dise knife dish and be located between upper and lower dise knife dish is many strip shape cutoff tool, the blade of described cutoff tool outwardly, two the conical blocks be oppositely arranged are provided with inside cutoff tool top and the bottom, two conical blocks are equipped with screw rod, and described upper and lower dise knife panel surface is provided with the groove at spacing strip shape cutoff tool two ends.Cannot touch after the utility model overcomes edge wear and be cut the problem of polyester staple fiber, thus without the need to the cutoff tool of continuous retirement price costliness.
Description
technical field:
The utility model relates to a kind of cutters for PET staple fiber re-use device.
background technology:
Due to the current national production capacity of polyester staple fiber, supply exceed demand, and market competition is quite fierce, and therefore the control of production cost is just suitable important.The cutoff tool used in polyester staple fiber aft-loaded airfoil production process, continuous seepage three batches of silks, knife edge rust, knife edge rust cutoff tool will carry out magic sword to the knife edge to grinding machine, like this through grinding machine continuously to repeatedly repeatedly after magic sword, the broadband of cutoff tool will narrow, when the width of cutoff tool is too narrow to a certain degree, put into the cutter groove of Cutting cutter, the cutting action to polyester staple fiber will be completed, and such cutoff tool re-uses in process, the staple fibre quality cut off declines very large, length not only after polyester staple fiber cut-out does not reach the process length of technological requirement, and cut off terylene short fiber in overlength and double-length content increase, quality index is arrived national standard.In order to ensure the quality of products, have to regularly scrap the cutoff tool that these broadbands do not reach requirement.
These cutoff tools all will be scrapped and work as waste disposal to fall usually.Therefore the loss that annual because above-mentioned reason causes is larger, and production cost is higher.The cutoff tool scrapped because of above-mentioned reason every year by applicant company 09 year, 10 years, 11 years, 12 years, 13 annuals produces quantity and calculates, and about 7800 are assigned the cutoff tool of left and right as waste disposal.Because cutoff tool is placed on the Cutting cutter of High Rotation Speed, the material of therefore tool setting requires very high, and the price of cutoff tool is always all very expensive, especially import cutter, and price is two times of domestic cutter.
summary of the invention:
The purpose of this utility model is to provide a kind of cutters for PET staple fiber re-use device, and this apparatus structure is simple, reasonable in design, is conducive to reducing scrapping of cutoff tool.
The utility model cutters for PET staple fiber re-use device, it is characterized in that: what include upper and lower dise knife dish and be located between upper and lower dise knife dish is many strip shape cutoff tool, the blade of described cutoff tool outwardly, two the conical blocks be oppositely arranged are provided with inside cutoff tool top and the bottom, two conical blocks are equipped with screw rod, and described upper and lower dise knife panel surface is provided with the groove at spacing strip shape cutoff tool two ends.
Further, 108 cuttves are provided with between above-mentioned upper and lower dise knife dish.
Further, the spacing of above-mentioned upper and lower dise knife dish is fixed, and is provided with the through hole passed in order to conical block in portion of upper and lower dise knife disk center.
The operation principle of the utility model cutters for PET staple fiber re-use device: much knives are located at, between lower round knife dish, blade outwardly, upper, lower round knife dish operationally rotary motion, cut off by two cutoff tools after cutoff tool coordinates with roller, after use a little time, cutoff tool blade is by blunt, turn screw rod can be passed through, make the pitch smaller between two conical blocks, on, cutoff tool between lower round knife dish is namely by past extrapolation, thus cannot touch after overcoming edge wear and cut the problem of polyester staple fiber, thus without the need to the cutoff tool of continuous retirement price costliness.
These cutoff tools scrapped in a large number just normally can put into production and employ, and the polyester staple fiber that the cutoff tools to scrap with these cut off, not only shearing length can reach GB/T-2000 standard completely, and the standby long polyester staple fiber also cut out with normal cutoff tool of overlength is as broad as long.
Terylene short fiber aft-loaded airfoil import cutoff tool, open market price is 1350 yuan/left and right, domestic general 750 yuan/, the quantity of the cutoff tool scrapped every year according to past 5 years calculates, if these are scrapped cutter from newly becoming normal cutter recycling, annual reduction purchases cutter cost 78,00*,135,0=1,053 ten thousand.
accompanying drawing illustrates:
Fig. 1 is organigram of the present utility model;
Fig. 2 is the A-A sectional drawing of Fig. 1;
Fig. 3 is the top view of Fig. 1.
detailed description of the invention:
The utility model cutters for PET staple fiber re-use device, what include upper and lower dise knife dish 1,2 and be located between upper and lower dise knife dish is many strip shape cutoff tool 3, the blade of described cutoff tool outwardly, two the conical blocks 4 be oppositely arranged are provided with inside cutoff tool top and the bottom, two conical blocks are equipped with screw rod 5, and described upper and lower dise knife panel surface is provided with the groove 6 at spacing strip shape cutoff tool two ends.The width of groove is suitable with the width of normal cutoff cutter, and the degree of depth of groove is 1 centimetre.
Further, be provided with 108 cutoff tools 3 between above-mentioned upper and lower dise knife dish, the blade face of cutoff tool 3 becomes 8 degree of angles with mistake edge line with two faces, dise knife dish axial line place.
Further, the spacing of above-mentioned upper and lower dise knife dish is fixed, and is provided with the through hole 7 passed in order to conical block 4 in portion of upper and lower dise knife disk center.Upper and lower dise knife dish is fixed by several iron releasable connections, and iron two ends can be screw threads, thus realize releasable connection.
The operation principle of the utility model cutters for PET staple fiber re-use device: much knives are located at, between lower round knife dish, blade outwardly, upper, lower round knife dish operationally rotary motion, cut off by two cutoff tools after cutoff tool coordinates with roller, after use a little time, cutoff tool blade is by blunt, turn screw rod can be passed through, make the pitch smaller between two conical blocks, on, cutoff tool between lower round knife dish is namely by past extrapolation, thus cannot touch after overcoming edge wear and cut the problem of polyester staple fiber, thus without the need to the cutoff tool of continuous retirement price costliness.
These cutoff tools scrapped in a large number just normally can put into production and employ, and the polyester staple fiber that the cutoff tools to scrap with these cut off, not only shearing length can reach GB/T-2000 standard completely, and the standby long polyester staple fiber also cut out with normal cutoff tool of overlength is as broad as long.
Terylene short fiber aft-loaded airfoil import cutoff tool, open market price is 1350 yuan/left and right, domestic general 750 yuan/, the quantity of the cutoff tool scrapped every year according to past 5 years calculates, if these are scrapped cutter from newly becoming normal cutter recycling, annual reduction purchases cutter cost 78,00*,135,0=1,053 ten thousand.
