Abstract
The utility model discloses a limit self-locking device for automatic coil change of a blown film winding machine. The device is characterized by comprising a slider body, a self-locking cam mechanism fixed at the upper end of the slider body, and a slider body lifting cylinder fixed at the lower end of the slider body, wherein the upper end of the slider body lifting cylinder is connected with a slider for limiting an air expansion shaft bearing. The limit self-locking device disclosed by the utility model can realize automatic coil change, prevents string or loosening of the air expansion shaft bearing in the work, improves the working efficiency and reduces the production cost.
Description
Technical field
The utility model relates to parts on the blown film winder, and it is a kind of limit self device that is used for the automatic change of lap of blown film winder in particular.
Background technology
Existing winder can not be realized automatic change of lap, and the inflatable axle bearing takes place to go here and there moving or draw loose phenomenon at work easily, influences work efficiency, and safety misadventure takes place easily.
Summary of the invention
The purpose of the utility model is to overcome the weak point of above-mentioned prior art and a kind of limit self device that is used for the automatic change of lap of blown film winder is provided.
The purpose of the utility model reaches through following measure: the limit self device that is used for the automatic change of lap of blown film winder; It is characterized in that: it comprises slide body; Be fixed on the self-locking cam mechanism of slide body upper end; Be fixed on the slide body lift cylinder of slide body lower end, the upper end of slide body lift cylinder is connected with the slide block that is used to limit the inflatable axle bearing.
In technique scheme; Said self-locking cam mechanism comprises self-locking cam, locating dowel pin, rotating shaft, extension spring and shell fragment, and an end of said extension spring is fixed on the slide body, and the other end is fixed on the shell fragment; Shell fragment and self-locking cam are hinged through rotating shaft, and said locating dowel pin is fixed on the slide body.
In technique scheme, an end of said locating dowel pin is fixed on the slide body, and the other end is positioned at the arc shaped groove on the self-locking cam.
The utlity model has following advantage: the automatic change of lap of this rolling function, it is moving or draw loose phenomenon to prevent that the gas expansion shaft bearing from string taking place at work, increases work efficiency, and reduces production costs.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Structural representation when Fig. 2 is the change of lap of the utility model.
Among the figure: 1. slide body, 2. self-locking cam mechanism, 3. slide body lift cylinder, 4. slide block, 5. inflatable axle bearing, 6. self-locking cam, 7. locating dowel pin, 8. rotating shaft, 9. extension spring, 10. shell fragment, 11. upset shift forks, 13. subsequent use inflatable axles.
The specific embodiment
Below in conjunction with the performance of accompanying drawing detailed description the utility model, but they do not constitute the qualification to the utility model, only do for example.The clear more and understanding easily that will become through the advantage that the utility model is described simultaneously.
Consulting accompanying drawing can know: the limit self device that is used for the automatic change of lap of blown film winder; It comprises slide body 1, is fixed on the self-locking cam mechanism 2 of slide body 1 upper end, is fixed on the slide body lift cylinder 3 of slide body 1 lower end; The upper end of slide body lift cylinder 3 is connected with the slide block 4 that is used to limit gas expansion shaft bearing 5; Self-locking cam mechanism 2 comprises self-locking cam 6, locating dowel pin 7, rotating shaft 8, extension spring 9 and shell fragment 10, and an end of extension spring 9 is fixed on the slide body 1, and the other end is fixed on the shell fragment 10; Shell fragment 10 cuts with scissors through rotating shaft 8 with self-locking cam 6; Locating dowel pin 7 is fixed on the slide body 1, and an end of locating dowel pin 7 is fixed on the slide body 1, and the other end is positioned at the arc shaped groove (as shown in Figure 1) on the self-locking cam 6.
During work; The subsequent use inflatable axle 13 of backup station is placed into working position exactly through upset shift fork 11; It is spacing and pin to fall into the inflatable axle bearing 5 of working position through slide body 1, slide block 4, self-locking cam 6, extension spring 9, prevents it and in working position, go here and there the moving pine of perhaps drawing.During change of lap; Slide block 4 is in the emersion position, and slide body 1 is positioned at working position to be waited for, when 11 rotations of upset shift fork are put into work with subsequent use inflatable axle 13, depresses self-locking cam 6; Back, the position self-locking cam 6 under extension spring 9 effects that falls upwards rotates and pins inflatable axle bearing 5; When slide block 4 is in lowering position, finish the work in inflatable axle bearing 5 position that falls.
