Abstract
The utility model provides a kind of upper pin with two propareas pressure bar, by two pressure bar structure additional in proparea, increase the control of upper and lower cushion rubber jaw to the floating fiber of front roller, make gathering of fiber in the yarn after drawing-off, reduce the scattering and disappearing before twisting of the fiber after drawing-off, reduce broken end, improve spinning efficiency and yarn quality.
Description
Technical field
The utility model relates to spinning new technical field, relates to a kind of upper pin with two propareas pressure bar specifically.
Background technology
Upper pin is the critical component in spun yarn drafting, the jaw of upper pin, downside pin and roller composition is the key area in spun yarn drafting, wherein, jaw is drawing-off jaw, front jaw grips jaw, therefore, change trickle in any structure of upper pin all can bring significant impact to the drawing-off of yarn, and the jaw of upper pin and roller composition also directly affects curable grip in drafting process and friction field, also determine the district of swimming in drafting process simultaneously, dry to the bar of yarn, filoplume, strong influence are fairly obvious.Sell traditionally and be not with pressure bar, just spacing block pressure bar must be installed additional as needed plus-pressure rod, it is fixed on upper pin by spacing block, novel upper pin with proparea pressure bar is fixed on by pressure bar on upper pin, be connected with upper pin, then the upper and lower cushion rubber jaw of better control is to the floating fiber of front roller, improves yarn quality.
The upper pin of the band proparea pressure bar of current use all adopts single pressure bar structure, not enough to the floating fiber control of front roller when making to spin, fiber after drawing-off was scattered and disappeared before twisting more, occur the more phenomenon of broken end, affect spinning efficiency and yarn quality.For this, the utility model provides a kind of upper pin with two propareas pressure bar, by two pressure bar structure additional in proparea, increase the control of upper and lower cushion rubber jaw to the floating fiber of front roller, make gathering of fiber in the yarn after drawing-off, reduce the scattering and disappearing before twisting of the fiber after drawing-off, reduce broken end, improve spinning efficiency and yarn quality.
Summary of the invention
The purpose of this utility model provides a kind of upper pin with two propareas pressure bar, by two pressure bar structure additional in proparea, increase the control of upper and lower cushion rubber jaw to the floating fiber of front roller, make gathering of fiber in the yarn after drawing-off, reduce the scattering and disappearing before twisting of the fiber after drawing-off, reduce broken end, improve spinning efficiency and yarn quality.
In order to achieve the above object, the technical solution adopted in the utility model is: a kind of upper pin with two propareas pressure bar, comprise proparea pressure bar and upper pin, described upper pin comprises link and shank, described shank comprises left shank, right shank is connected shank with centre, connect shank in the middle of described and comprise middle shank and left pressure bar link, right pressure bar link, described left pressure bar link, right pressure bar link starting section is trapezium structure, at described left pressure bar link, circular port is had in the middle of right pressure bar link, described pressure bar comprises upwards Bonding pressure rod and actuating pressure rod, described upwards Bonding pressure rod and actuating pressure excellent between angle be 90 °, described proparea pressure bar passes through upwards Bonding pressure rod and is embedded into the left pressure bar link of pin respectively, integration both realizing in circular port in the middle of right pressure bar link connects, described actuating pressure rod comprises previous crops pressure bar and rear actuating pressure rod, described previous crops pressure bar and rear actuating pressure rod surface and corresponding left shank or right shank surface are in the same horizontal line.
During use, yarn after drawing-off successively through previous crops pressure bar and after actuating pressure rod, thus increase the control of upper and lower cushion rubber jaw to the floating fiber of front roller, make gathering of fiber in the yarn after drawing-off, reduce the scattering and disappearing before twisting of the fiber after drawing-off, reduce broken end, improve spinning efficiency and yarn quality.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the upper pin of band of the present utility model two propareas pressure bar.
Detailed description of the invention
As shown in Figure 1, a kind of upper pin with two propareas pressure bar, comprise proparea pressure bar 2 and upper pin 1, wherein go up pin 1 and comprise link 3 and shank 4, shank 4 comprises left shank 5, right shank 6 is connected shank 7 with centre, the middle shank 7 that connects comprises middle shank and left pressure bar link 8, right pressure bar link 9, left pressure bar link 8, right pressure bar link 9 starting section is trapezium structure, at left pressure bar link 8, circular port is had in the middle of right pressure bar link 9, pressure bar 2 comprises upwards Bonding pressure rod 10 and actuating pressure rod 11, angle upwards between Bonding pressure rod 10 and actuating pressure rod 11 is 90 °, proparea pressure bar 2 is divided by upwards Bonding pressure 10 rod and is embedded into the left pressure bar link 8 of upper pin, integration both realizing in circular port in the middle of right pressure bar link 9 connects, actuating pressure rod 11 comprises previous crops pressure bar 13 and rear actuating pressure rod 12, previous crops pressure bar 13 and rear actuating pressure rod 12 surface and corresponding left shank 5 or right shank 6 surface are in the same horizontal line.
During use, yarn after drawing-off successively through previous crops with pressure bar 13 and after actuating pressure rod 12, thus increase the control of upper and lower cushion rubber jaw to the floating fiber of front roller, make gathering of fiber in the yarn after drawing-off, reduce the scattering and disappearing before twisting of the fiber after drawing-off, reduce broken end, improve spinning efficiency and yarn quality.
