Abstract
The utility model provides a safety structure of a chinlon metering pump rotating shaft. The metering pump rotating shaft is connected with a connector of a motor through a sliding sleeve. A connector insertion hole and a rotating shaft insertion hole are formed in the sliding sleeve. The metering pump rotating shaft is arranged inside the rotating shaft insertion hole. The connector of the motor is arranged inside the connector insertion hole. The safety structure comprises two safety pins, a first safety pin insertion hole and two second safety pin insertion holes. Any safety pin is provided with a safety head. A transverse fracture groove is formed in each safety head. The first safety pin insertion hole is transversely formed in the connector of the motor. The two second safety pin insertion holes are transversely formed in the sliding sleeve. The two second safety pin insertion holes are correspondingly jointed with the first safety pin insertion hole. The two safety pins are respectively inserted into the first safety pin insertion hole through the two second safety pin insertion holes respectively. According to the safety structure of the chinlon metering pump rotating shaft, in the operating process, after the safety pins are fractured, the rotating shaft can stop operating, and therefore product quality and equipment safety can be ensured.

In the polyamide fibre production process, because the arming pin of metering pump rotatingshaft is a horizontal unitary pin that is inserted on metering pump rotatingshaft outer sliding sleeve and the dwang, behind the operation process Fracture, arming pin does not come off and causes the metering pump rotatingshaft to continue in running, the easy damaged metering pump, thereby the silk thread fiber number is changed, cause silk thread plucked to occur and the phenomenon of Accident due to quality occurs; When maintenance, dismantle extremely inconvenient after the arming pin fracture.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of safety structure of polyamide fibre metering pump rotatingshaft, and rotatingshaft can shut down after the arming pin fracture in operation process, guarantees quality of product and device security.
The utility model is achieved in that a kind of safety structure of polyamide fibre metering pump rotatingshaft, described metering pump rotatingshaft is connected with the connecting head of motor by a sliding sleeve, described sliding sleeve is provided with a connecting head jack and rotatingshaft jack, described metering pump rotatingshaft is located in the rotatingshaft jack, the connecting head of described motor is located in the connecting head jack, described safety structure comprises the first arming pin jack, two second arming pin jacks and two are independence and the equirotal arming pin of specification respectively, described arbitrary arming pin has an insurance head, the insurance head is provided with a transverse breakage groove, described the first arming pin jack laterally is located on the connecting head of described motor, described two second arming pin jacks for laterally be located on the described sliding sleeve to the hole, and two second arming pin jacks and the corresponding linking of the first arming pin jack, the insurance head of described two arming pins inserts the first arming pin jack by two second arming pin jacks respectively.
Better, described transverse breakage groove is in the joining place of the second arming pin jack and the first arming pin jack.
Better, the ends of two described insurance heads are separated with distance mutually, the length of this distance be not less than described motor the connecting head diameter 15%.
Better, the width of rebate of described transverse breakage groove is 2.5mm, the base diameter of transverse breakage groove is 3.2mm.
Better, described arbitrary arming pin also has a nut, and this nut is connected to the outer end of insurance head.
The utility model has the advantage of: arming pin structure of the present utility model has two arming pins, form new safety structure, rotatingshaft can shut down after the arming pin fracture in operation process, guarantee quality of product and device security, therefore the silk thread fiber number can not change, and the Accident due to quality phenomenon generation of silk thread plucked occurs; Become convenient when when maintenance, dismantling and reinstalling after the arming pin fracture.
Description of drawings
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
Fig. 1 is the structural representation of the safety structure preferred embodiment of the utility model polyamide fibre metering pump rotatingshaft.
Fig. 2 is the exploded view of Fig. 1.
Fig. 3 is the local enlarged diagram of Fig. 1.
Embodiment
See also Fig. 1 to shown in Figure 3, safety structure 1 of the present utility model, insurance when being used for providing polyamide fibre metering pump rotatingshaft 2 to be connected with motor, described metering pump rotatingshaft 2 is connected with the connecting head 4 of motor by a sliding sleeve 3, described sliding sleeve 3 is provided with a connecting head jack 31 and rotatingshaft jack 32, described metering pump rotatingshaft 2 is located in the rotatingshaft jack 32, the connecting head 4 of described motor is located in the connecting head jack 31, described safety structure 1 comprises the first arming pin jack 11, two second arming pin jacks 12 and two are independence and the equirotal arming pin 13 of specification respectively, described arbitrary arming pin 13 has insurance 131 and one nut 132, this nut 132 is connected to the outer end of insurance 131, insurance 131 is provided with a transverse breakage groove 133, described the first arming pin jack 11 laterally is located on the connecting head 4 of described motor, described two second arming pin jacks 12 for laterally be located on the described sliding sleeve 3 to the hole, and two second arming pin jacks 12 and the 11 corresponding linkings of the first arming pin jack, the insurance of described two arming pins 131 insert in the first arming pin jack 11 by two second arming pin jacks 12 respectively.
Described transverse breakage groove 133 is in the joining place of the second arming pin jack 12 and the first arming pin jack 11.
The end of two described insurances 131 is separated with distance L mutually, the length of this distance L be not less than described motor connecting head 4 diameter d 15%.
The notch H width of described transverse breakage groove 133 is 2.5mm, and the base diameter D of transverse breakage groove is 3.2mm.
Safety structure of the present utility model in use, first metering pump rotatingshaft 2 and sliding sleeve 3 are connected, connecting head 4 with motor inserts in the connecting head jack 31 again, after making the first arming pin jack 11 and the 12 corresponding linkings of two second arming pin jacks, the insurance of two arming pins 131 inserted in the first arming pin jack 11 by two second arming pin jacks 12 respectively get final product.After the arming pin fracture, arming pin easily comes off and metering pump rotatingshaft 2 is shut down metering pump in operation process, easy damaged metering pump not, and therefore the silk thread fiber number can not change, and the Accident due to quality phenomenon that the silk thread plucked occurs occurs; The time become more convenient in maintenance, after arming pin 13 fractures, as long as sliding sleeve 3 is removed, back out two nuts 132, just from jack, disclose and to have reinstalled new arming pin insuring 131 with iron wire.
