Description

The drawing frame automatic strip breaker is put

Technical field:

The utility model relates to technical field of textile machine, and exactly it is that a kind of drawing frame automatic strip breaker is put, and is used in machinery such as drawing frame, carding machine.

Background technology:

In textile industry, the finished product of drawing frame and carding machine is in order to be transported to subsequent processing safely and effectively, all be closely to put in the sliver can in an orderly manner the finished product sliver, a big stage clip is equipped with in sliver can inside, purpose is to make the sliver of putting in the sliver can and encloses between the bar dish and produces certain pressure, guarantees that its moulding is good.Behind full tube, when changing new sliver can, need sliver is pulled apart.Along with improving constantly of automaticity, generally all adopt the automatic creeling of mechanical type at present, the problem that the sliver after full is broken has automatically appearred thereupon.

At present, use more strip breaker and put main branch two classes: a class is disconnected automatically bar, and it comprises two kinds of patterns again: a kind of is false car face by lengthening, increase sliver and car face relative motion length, and frictionally is pulled apart sliver.Another kind is to adorn a revolvable rubber roll on false car face, pulls apart sliver by chucking power between rubber roll and sliver.These two kinds of patterns generally only are suitable for staple fibres such as cotton textiles, and the above fiber of middle length pulls constantly; Another kind of is the mechanical type bar that initiatively breaks, and it is to form with two pairs of clamp bar posts and a disconnected bar post, when breaking bar, by making actuation mechanism drive the relative motion of clamp bar post, two pairs of clamp bar posts grip sliver live, and disconnected bar post is passed through from two pairs of clamp bar intercolumniations, and sliver is broken.Though this mechanism strip-breaking rate is higher, complex structure, it is big to take up room, and does not still have practical at present.China Patent No. 01208912.5 discloses the utility model patent that a kind of name is called " the sliver automatic disconnecting device of drawing frame ", and it adopts two disconnected formula location, utilizes the displacement of male and female holder, cuts off sliver by cutting cotton sheet.This apparatus structure complexity, and destroy fibr tissue, reality is not seen application.Also have China Patent No. 200320128691.0 to disclose the utility model patent that a kind of name is called " drawing frame sprays strip breaker and puts ", its operation principle is behind full tube, signal by PLC, jet control electromagnetic valve is connected, compressed air is through pressure regulation, from the nozzle ejection, sliver is blown disconnected in the circle plate inclined tube porch after the speed governing.Though the disconnected bar of this device is reliable, it is at random fluffy to be blown disconnected sliver, when driving again, and easily stifled circle plate inclined tube.Do not see practicality at present yet.Therefore need automatically disconnected bar a kind of simple in structure, safe and reliable to solve this practical problem.

Summary of the invention:

The purpose of this utility model provides the automatic strip breaker of drawing frame in a kind of textile machinery industry, carding machine use and puts.It comprises: cylinder 1, flow speed control valve 2, cylinder block 3, left side die 4 and right die 5, left side die slide rail 6 and right die slide rail 7, hinged seat 8, bearing pin 9, pad 10, flange bearing 11, sleeve 12, cotton pressure roller 13, left side roller seat 14, middle roller seat 15, right roller seat 16, turnover panel 17, die cover 18, hinge 19, substrate 20, cylinder 21,22, gripper shoe 23, near switch 24, catch 27, hold-down screw, it is characterized in that: cylinder 1 relies on cylinder block 3 to be installed in substrate 20 soil, left side die slide rail 6 and right die slide rail 7 are contained on the substrate 20 that flange bearing 11 is housed, and guarantee that with catch 27 it rotates flexibility, left side die 4 and right die 5 connect with cylinder 1 usefulness hinge seat 8 and bearing pin 9, and be controlled by left die slide rail 6 and right die slide rail 7, cotton pressure roller 13 usefulness left, center, right cotton roller seats 14,15,16 are contained on the turnover panel 17, flange bearing 11 is contained in rotating shaft place, turnover panel 17 usefulness hinges 19 are contained on the circle bar disk cover plate, gripper shoe 23 is contained between circle bar disk cover plate and the cylinder 21, to strengthen the rigidity of circle bar disk cover plate, be contained on the circle bar dish near switch 24.By the linkage of cylinder 1 left and right sides die 4,5 left and right sides slide rails 6,7 hinged seats 8 bearing pins 9 assembling can make die 4,5 by horizontal level to the upright position, again by the upright position to horizontal level.

When full tube was released, turnover panel 17 was lifted by the bar tube, and cotton roller 13 compresses sliver, and when normally driving, turnover panel 17 is in sagging position.Low in the die cover 18 outer height.Advantage of the present invention is that delicate structure is simple, and it is little to occupy the space, safe and reliable, sliver end breakage rate height, applicable in cotton textiles, various chemical fibres, wool, the rabbit hair etc., long fiber.

The specific embodiment:

The utility model all can be produced in general machining factory.It is the improvement on the existing equipment of keeping off a car.Cylinder 1 relies on cylinder block 3 to be installed on the substrate 20, left side die slide rail 6 and right die slide rail 7 are contained on the substrate 20 that flange bearing 11 is housed, and guarantee that with back-up ring 27 it rotates flexibility, left side die 4 and right die 5 connect with cylinder 1 usefulness hinge seat 8 and bearing pin 9, and be controlled by left die slide rail 6 and right die slide rail 7, cotton pressure roller 13 usefulness left, center, right cotton roller seats 14,15,16 are contained on the turnover panel 17, flange bearing 11 is contained in rotating shaft place, turnover panel 17 usefulness hinges 19 are contained on the circle bar disk cover plate, gripper shoe 23 is contained between circle bar disk cover plate and the cylinder 21, to strengthen the rigidity of circle bar disk cover plate, be contained near circle bar Pan Chu near switch 24.During circle bar dish oriented stopping, cotton pressure roller 13 is pushed out in the process at full tube noodles tube can push the sliver that firmly will be interrupted.And make this section sliver between dish outlet of circle bar and cotton roller, produce certain tensile force.By the linkage of assemblings such as cylinder 1, left and right sides die 4,5, left and right sides slide rail 6,7, hinged seat 8, bearing pin 9 make die 4,5 by horizontal level to the upright position, again by the upright position to horizontal level.The application of turnover panel 17, when full tube was released, turnover panel 17 was lifted by the bar tube, and cotton roller 13 compresses sliver, and when normally driving, turnover panel 17 is sagging.Die cover 18 except that playing the safeguard protection effect also for spinner's handling failure provides an operating platform, low in its outer height, when the spinner puts as parts such as rollers during operation, can not be slipped on the ground, guarantee spinner's personal safety, avoid the generation of operating irregularity.
