Abstract

The utility model discloses an open cotton roller suitable for wet opener relates to spinning machine technical field. The device includes the roll body, sets up the spindle nose at the roll body both ends respectively to and encircle the eight rows divisions of cotton brads that the roll body circumference set up, wherein, each row opens cotton brad and all adopts by the be V word arrangement overall arrangement mode setting of both ends to the middle part skew, and two rows of brad staggered arrangement of every double -phase neighbour, it adopts screw thread and the sealed confined mode of gluing to install at roll body processed nail inslot respectively to open cotton brad. The utility model discloses a difficult point of 80, 000 tons and above viscose production line has been overcome to wet the opening that can satisfy 80, 000 tons and above viscose fiber production line (50-70mm cotton blanket), has promoted the development of large capacity viscose production line.

Description

A kind of opener roller being applicable to wet opener

Technical field

The utility model relates to technical field of textile machine, relates to a kind of opener roller being applicable to wet opener specifically.

Background technology

In textile industry, wet opener is mainly used in the wet shredding of viscose staple fibre after refining, high pressure squezzing, and the opener roller in wet opener belongs to the core component in the machine.The structural shape of opener roller directly affects shredding effect, and within annual output 50000 tons in viscose fiber production line, generally adopt the opener brad of structure as shown in Fig. 4, Fig. 4, opener roller circumference uniform distribution 12 arranges little brad, adjacent two row's brad cross arrangements.Because this structure brad is arranged in a straight line, nail length is partially short, and holding capacity is little, is usually used in shredding 30 ~ 45mm and wets cotton blanket, and the wet cotton blanket thickness of large output viscose fiber production line is usually between 50 ~ 70mm, and this structure can not meet instructions for use.

Summary of the invention

The purpose of this utility model provides for weak point existing in above-mentioned prior art the wet opener opener roller that a kind of structure is more reasonable, satisfy the demands just.

The purpose of this utility model realizes by following technical scheme:

The opener roller being applicable to wet opener of the present utility model comprises roll body, be separately positioned on the spindle nose at roll body two ends, and arrange cotton brad around eight of roll body circumference setting, wherein, each arranges cotton brad and all adopts by two ends arranging in V word arrangement layout type to middle part skew back, and every two adjacent two row's brads are staggered, the mode that described opener brad adopts screw thread and fluid sealant to close respectively is arranged in the nail groove that roll body processes.

The utility model is respectively arranged with vexed plate by the mode of interference fit and welding in the cavity at described roll body two ends, have annular end cap in roll body both ends of the surface by connecting bolt shutoff, the central shaft hole of annular end cap is passed by welding manner and vexed plate Joint in the inner of described spindle nose.

Opener brad described in the utility model is made up of cone segments and the section of being threaded being positioned at facies basialis pyramidis, and centerline offset is in side, roll body axis.

The beneficial effects of the utility model are as follows:

Because the utility model adopts the opener brad be made up of with the section of being threaded being positioned at facies basialis pyramidis cone segments, and by opener brad to arrange around roll body circumference uniform distribution eight, each arranges cotton brad and all adopts by two ends arranging in V word arrangement layout type to middle part skew back, and every two adjacent two row's brads are staggered, the mode that described opener brad adopts screw thread and fluid sealant to close respectively is arranged on the nail groove inner structure mode that roll body processes, the wet shredding of 80,000 tons and above viscose fiber production line (50 ~ 70mm cotton blanket) can be met, overcome a difficult point of 80,000 tons and above viscose glue production line, promote the development of Large Copacity viscose glue production line.
