A kind of chemical fibre package doff machine supporting arm safety pin apparatus
Technical field
The utility model relates to a kind of chemical-fibres filaments automatic doffer, especially relates to the safety pin mechanism on a kind of chemical fibre package doff machine hold-down arm.When this device can effectively prevent the motion of doff machine, (when hold-down arm rotates or moves) package moves axially to cause along hold-down arm and falls, in the time that package is loaded and unloaded, can be easy to open again.
Background technology
In the time of chemical fiber filament winding moulding, winding filament forms the package of pie structure on paper web, and several packages are arranged on up-coiler chuck, after coiling and molding, package must be taken off from up-coiler chuck, and transfer on doff machine hold-down arm, then be transferred to by doff machine on the rolling truck of postorder.Current doff machine is owing to there is no actv. safety pin apparatus, in the time that doff machine moves (hold-down arm support rotation or mobile), package is vibrated and is made to arrange not tight, package likely moves axially to cause along hold-down arm to be fallen, and positioning precision is not high, cannot match with whole long filament automatic production process.
Summary of the invention
The purpose of this utility model is to provide a kind of chemical fibre package doff machine supporting arm safety pin apparatus, can effectively solve the defect existing in prior art, and improve the reliability of doff.
In order to achieve the above object, the utility model provides a kind of chemical fibre package doff machine supporting arm safety pin apparatus, it is characterized in that, comprise guide pin bushing, spring and push rod, the overcoat of guide pin bushing has hold-down arm end cap and cover plate, described hold-down arm end cap is located at one end of hold-down arm and is not stopped the package of being located on hold-down arm, in package, there is paper tube, hold-down arm end cap is fixedly connected with cover plate, cover plate is located at hold-down arm inside, guide pin bushing can be inner mobile to hold-down arm with respect to hold-down arm end cap, the sidewall of guide pin bushing is fixedly connected with drive plate, drive plate is provided with the bar hole of inclination, one end of push rod is fixed in described bar hole and can be moved along bar hole by contact plug, one end of spring is against cover plate, the other end is against guide pin bushing or drive plate, when spring is during in initial compressed state, the other end of push rod exposes and blocks the paper tube of package from hold-down arm end cap, in the time that guide pin bushing moves inward with respect to hold-down arm end cap, spring is in further compressive state, one end of push rod moves down along bar hole, in the time that push rod is moved down into certain position, the other end of push rod does not stop the paper tube of package.
Preferably, the outer end of described guide pin bushing is fixedly connected with impact head.
More preferably, described impact head and guide pin bushing are threaded connection or rivet.
Preferably, the other end of described hold-down arm connects hold-down arm support.
Preferably, described hold-down arm end cap and cover plate is connected by screw.
Compared with prior art, the beneficial effects of the utility model are:
Safety pin of the present utility model mechanism is arranged on hold-down arm end, and can effectively prevent the motion of doff machine time, package is fallen, and in the time that package is loaded and unloaded, can be easy to open again, can effectively solve the defect existing in prior art, and improve the reliability of doff.

Detailed description of the invention
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiment 1
As shown in Figure 1, be chemical fibre package doff machine hold-down arm schematic diagram, described chemical fibre package doff machine supporting arm safety pin apparatus 4 is located at one end of hold-down arm 2, and the other end of hold-down arm 2 connects hold-down arm support 1, and on hold-down arm 2, cover has package 3.
As shown in Figure 3, described chemical fibre package doff machine supporting arm safety pin apparatus, comprise guide pin bushing 4.4, spring 4.8 and push rod 4.7, the overcoat of guide pin bushing 4.4 has hold-down arm end cap 4.1 and cover plate 4.2, described hold-down arm end cap 4.1 is located at one end of hold-down arm 2 and is not stopped the package 3 of being located on hold-down arm 2, in package 3, there is paper tube 3.1, hold-down arm end cap 4.1 is fixedly connected with cover plate 4.2, cover plate 4.2 is located at hold-down arm 2 inside, guide pin bushing 4.4 can be inner mobile to hold-down arm 2 with respect to hold-down arm end cap 4.1, the sidewall of guide pin bushing 4.4 is fixedly connected with drive plate 4.5, drive plate 4.5 is provided with the bar hole of inclination, one end of push rod 4.7 is fixed in described bar hole and can be moved along bar hole by contact plug 4.6, one end of spring 4.8 is against cover plate 4.2, the other end is against guide pin bushing 4.4 or drive plate 4.5, as shown in Figure 2, when spring 4.8 is during in initial compressed state, the other end of push rod 4.7 exposes and blocks the paper tube 3.1 of package 3 from hold-down arm end cap 4.1, in the time that guide pin bushing 4.4 moves inward with respect to hold-down arm end cap 4.1, spring 4.8 is further compressed, one end of push rod 4.7 moves down along bar hole, in the time that push rod 4.7 is moved down into certain position, the other end of push rod 4.7 does not stop the paper tube 3.1 of package 3.The outer end of described guide pin bushing 4.4 is fixedly connected with impact head 4.3.Described impact head 4.3 and guide pin bushing 4.4 are threaded connection.The other end of described hold-down arm 2 connects hold-down arm support 1.Described hold-down arm end cap 4.1 and cover plate 4.2 are connected by screw.
In the time of touching impact head 4.3, the guide pin bushing 4.4 connecting with impact head 4.3 drives drive plate 4.5 to move right, and contact plug 4.5 glides, and drives push rod 4.7 to be moved down into a certain position,, when winding apparatus is put on hold-down arm 2, complete after package doff; Impact head 4.3 touchings are unclamped, and drive plate 4.5 moves to left under the restoring force effect of compressed spring 4.8, thereby drive push rod 4.7 upward movements complete reset and the paper tube of package 3 3.1 is locked.
