Abstract
The utility model relates to a passive formula cam open -ended shuttleless loom prevents that heald frame damages device, its characterized in that: including frame, passive formula cam opening mechanism, comprehensive device and stop gear return, the crossbeam of connecting a horizontal direction setting between the support that the frame was set up by a pair of symmetry constitutes, installs stop gear on the crossbeam, this stop gear includes that one has the perpendicular body of rod and connection of external screw thread structure at the spacing body of rod on perpendicular body of rod top, the spacing body of rod extends to the top of each heald frame along the horizontal direction to the damping cover is equipped with at the external cover of gag lever post, the perpendicular body of rod is fixed on the crossbeam. The utility model discloses the advantage lies in: set up a spacing body of rod through the top at the heald frame to suit damping cover on the spacing body of rod makes the heald frame appear shifting up under the excessive circumstances can be by the restriction of the spacing body of rod, avoids in the high -speed motion heald frame to break away from whole loom equipment and leads to the fact the damage, simultaneously, avoids the heald frame to fly to take off the potential safety hazard that leads to the fact.
Description
Technical field
This utility model relates to a kind of loom, and the anti-heald frame of shuttleless loom particularly to a kind of passive type cam opening damages device.
Background technology
Shuttleless loom is after fly-shuttle loom, a kind of new loom of birth.Shuttleless loom is light with its component, it is little to vibrate, noise is low, speed is fast, efficiency advantages of higher, is widely used in loom industry.The filling insertion way of shuttleless loom is diversified, has the modes such as arrow shaft, injection (jet, water spray), projectile shuttle, multiple-shed (heterogeneous) and braiding.Wherein, weft yarn is drawn by the ejection-type shuttleless loom compressed air stream ejected, and weft tapes is crossed shed open.
Use the ejection-type shuttleless loom of passive type cam opening in the course of the work, its heald frame is the most quickly moved down by the traction of passive type cam shedding mechanism, promote heald frame downward, by the spring deformation power in return device, heald frame is returned back to home position again, complete the opening and closing movement of shed open.In this kind of shedding mechanism, whole system is all that the deformability by spring retrains.Therefore, heald frame is all upwards lifted by spring used.
But, owing to spring there to be high frequency response Capability Requirement, when loom operates, under certain conditions, appear in during heald frame pulled upper shifting by spring-return power, the harness threading steel wire rope being connected with opening arm due to lower end is because of fatigue fracture so that the phenomenon that heald frame pops up, and in turn results in heald frame and damages the most serious potential safety hazard.Therefore, research and develop a kind of it can be avoided that heald frame damages and to improve the auxiliary device of security reliability imperative.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of it can be avoided that heald frame damages and improves the shuttleless loom anti-heald frame damage device of security reliability.
For solving above-mentioned technical problem, the technical solution of the utility model is: the anti-heald frame of shuttleless loom of a kind of passive type cam opening damages device, its innovative point is: include frame, passive type cam shedding mechanism, return device and position-limit mechanism, described frame is made up of connection one horizontally arranged crossbeam between a pair symmetrically arranged support, some heald frames being positioned at crossbeam side it are provided with between two stands, described heald frame is driven by passive type cam shedding mechanism and moves vertically down, and the two ends of heald frame are connected with the return device being arranged on cantilever tip；On described crossbeam, position-limit mechanism is installed, this position-limit mechanism includes a vertical body of rod with external thread structure and the spacing body of rod being connected to vertical body of rod top, the top of described horizontally extending to each heald frame of the spacing body of rod, and have damping sleeve at gag lever post extracorporeal set, being drilled with the installing hole that axis is vertical direction on crossbeam, the described vertical body of rod is fixed on crossbeam by nut after crossbeam installing hole.
The utility model has the advantage of: by being provided above a spacing body of rod at heald frame, and on the spacing body of rod, it is set with damping sleeve, heald frame can be limited by the limited body of rod in the case of degree of moving past on occurring, avoid heald frame in high-speed motion to depart from whole weaving machine equipment and cause damage, simultaneously, it is to avoid heald frame flies off the potential safety hazard caused.
Accompanying drawing explanation
Fig. 1 is that the anti-heald frame of shuttleless loom of this utility model passive type cam opening damages device front view.
Fig. 2 is that the anti-heald frame of shuttleless loom of this utility model passive type cam opening damages the side view that device position-limit mechanism is arranged on crossbeam.
Detailed description of the invention
As shown in Figure 1, 2, including frame, passive type cam shedding mechanism, return device and position-limit mechanism.
Frame is made up of connection one horizontally arranged crossbeam 2 between a pair symmetrically arranged support 1, some heald frames 3 being positioned at crossbeam 2 side it are provided with between two stands 1, heald frame 3 is driven by passive type cam shedding mechanism 4 and moves vertically down, and the two ends of heald frame 3 are connected with the return device 5 being arranged on cantilever tip.
In this utility model, on crossbeam 2, position-limit mechanism is installed, this position-limit mechanism includes a vertical body of rod 6 with external thread structure and the spacing body of rod 7 being connected to the vertical body of rod 6 top, the top of spacing horizontally extending to each heald frame of the body of rod 73, and the spacing body of rod 7 is higher than the upper limit of heald frame 3 proper motion, and it is set with damping sleeve 8 outside the spacing body of rod 7, being drilled with the installing hole that axis is vertical direction on crossbeam 2, the vertical body of rod 6 is fixed on crossbeam 2 by nut 9 after crossbeam installing hole.
Operation principle:
Under normal operating conditions, heald frame 3 is drawn by passive type cam shedding mechanism 4 and the most quickly moves down, heald frame 3 is promoted to be formed down interface, now, the spring of return device 5 is stretched deformation accumulation of energy, and when passive type cam shedding mechanism 4 resets, heald frame 3 is returned back to home position by the spring release elastic deformation power in return device 5, complete the closed action of shed open, during being somebody's turn to do.When equipment breaks down so that after heald frame 3 rises and excessively departs from original upper limit, owing to the spacing body of rod 7 is positioned above, it is possible to avoid heald frame 3 to damage and completely disengage from equipment and eject and cause security incident.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description, principle of the present utility model is simply described; on the premise of without departing from this utility model spirit and scope; this utility model also has various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.This utility model claims scope and is defined by appending claims and equivalent thereof.
