Abstract
The utility model provides a testing device for surface negative pressure of a narrow-groove type hollow roller. The testing device comprises a cambered connecting surface and a connecting pipeline; a round hole in which screw threads are formed is formed in the middle part of the cambered connecting surface; the connecting pipeline comprises a connecting pipe of which the bottom is provided with screw threads and an upper smooth negative pressure gauge connecting pipe; in use, the cambered connecting surface is tightly fitted on the surface of a narrow-groove type hollow roller, the connecting pipeline is screwed in the round hole with the screw threads by virtue of the connecting pipe of which the bottom is provided with the screw threads and then connected with the cambered connecting surface, and the upper smooth negative pressure gauge connecting pipe is connected with a negative pressure gauge so that the surface negative pressure value of the narrow-groove type negative-pressure hollow roller can be obtained according to the reading of the negative pressure gauge. The testing device can be used for realizing convenient testing of the surface negative pressure of the narrow-groove type hollow roller, and then the internal negative pressure of the hollow roller can be adjusted according to actual spinning requirements, and therefore, the gathering effect can be improved and the quality of finished yarns can be improved.
Description
Technical field
The utility model relates to spinning new technical field, specifically a kind of narrow slot type hollow roller surface negative-pressure testing device.
Background technology
RING SPINNING is the topmost spun yarn mode of production of current China, and domestic current ring spinning number of spindles has surpassed 1.3 hundred million ingots, accounts for 2/3 of global spindle sum.Compact spinning is that RING SPINNING is carried out to improved a kind of Advanced Spinning Technologies, has become at present the heat subject in spinning field, and development practice is for many years told us: the world of following RING SPINNING belongs to compact spinning.At present, the compact spinning type that main flow is used in the world comprises lattice apron type (mainly comprising German Sussen tri-roller lattice apron types, Japanese Toyota tetra-roller lattice apron types), roller type (Switzerland's profit reaches the COM4 of Rieter), punching apron type (mainly comprising Zinser punching apron formula), mechanical type (mainly comprising Switzerland Carlos Roscraft magnetic centralization type compact spinning system), and lattice apron type, roller type and punching apron type belong to negative-pressure air-flow and gather mode.Wherein, the machinery centralization type compact spinning system of Roscraft is because the current use at home of the reasons such as varietal adaptation poor (being generally only applicable to 60Ne with the spinning of yarn under working) is less; Zinser punching apron formula is due to varietal adaptation poor (being generally only applicable to wool spinning) and need complete machine introduction, expensive (1500 yuan, average every ingot), so use scale is at home less.What therefore, occupy at present mainstream market is lattice apron type compact spinning.But in use mainly there is the problems such as operating cost is higher, maintaining is complicated, the life-span is short in lattice apron type compact spinning.Roller type compact spinning comes into one's own gradually, it is in energy consumption, machine material consumption and system maintenance cost aspect have some superiority compared with lattice apron type compact spinning, the COM4 of Rieter is most typical roller type compact spinning system, but this system is gathered surface of roller and is adopted pore structure, easily stop up, need often to clean, and the humiture to workshop is had relatively high expectations, increase maintenance cost, therefore, at patent tight spinning hollow bottom roller (patent No. ZL200820214736.9), provide the narrow slot type negative pressure hollow roller that a kind of surface has groove structure, its surface is narrow groove structure, solve roller type compact spinning system and in use easily produce the problems such as obstruction.For this, the utility model provides a kind of device that is applicable to the negative pressure test of narrow slot type hollow roller surface.This device comprises arc joint face and connecting line, on arc joint face, have inner screwed circular hole, connecting line comprises the screwed tube connector in bottom and upper smooth depressimeter tube connector, during use, arc joint face is close to narrow slot type hollow roller surface, the screwed tube connector in connecting line bottom is screwed on arc joint face in screwed circular hole, upper smooth depressimeter tube connector and depressimeter in succession, obtain the negative pressure value on narrow slot type negative pressure hollow roller surface then by the reading on depressimeter.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of device that is applicable to the negative pressure test of narrow slot type hollow roller surface.
In order to address the above problem, the technical scheme that the utility model is taked is: a kind of narrow slot type hollow roller surface negative-pressure testing device, comprise arc joint face and connecting line, at described arc joint face middle part, have inner screwed circular hole, described connecting line comprises the screwed tube connector in bottom and upper smooth depressimeter tube connector, during use, described arc joint face is close to narrow slot type hollow roller surface, described connecting line is screwed on arc joint face and is connected with arc joint face in screwed circular hole by the screwed tube connector in bottom, by upper smooth depressimeter tube connector and depressimeter in succession, then by the reading on depressimeter, obtain the negative pressure value on narrow slot type negative pressure hollow roller surface.
In technique scheme, the radian of described arc joint face is between 45-60 °, thickness is between 8-11mm, width is between 20-25mm, on described arc joint face, screwed Circularhole diameter is between 10-15mm, the screwed tube connector diameter in described tube connector bottom is between 8-13mm, and described tube connector upper smooth depressimeter tube connector diameter is between 7-10mm.
Adopt above-mentioned testing arrangement, can realize the convenient test to narrow slot type hollow roller surface negative pressure, according to reality, spinning need to be adjusted hollow roller internal negative pressure then, thereby improves compacting effect, improves yarn quality.
