Description
Technical Field
The utility model relates to the technical field of textile machinery, in particular to a multifunctional cam independent serging device.
Background
When the loom is running, the heald frame moves up and down, left and right according to the program, so that the warp yarns are opened in layers, and the weft yarns are shuttled in the warp yarns to be interwoven into fabrics with different patterns. However, in the fabric edge area, the warp yarns cannot effectively engage with the weft yarns, and the weft yarns lose tension and retract, so that the fabric edge is rough, namely the edge locking effect is poor.
Based on this, the present disclosure is thus directed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a multifunctional cam independent serging device which is independent of a heald frame to carry out layered opening and weft yarn occlusion on warp yarns at the edge part, and improves the serging effect of a fabric.
In order to achieve the purpose, the technical scheme of the utility model is as follows:
the utility model provides an independent serging device of multi-functional cam, includes the frame, through installing two lift axles of linear bearing symmetry in the frame, the epaxial rack that is equipped with of lift and two racks set up relatively, be equipped with in the frame one be located between two racks and with two rack toothing's gear, the epaxial cantilever and two cantilevers that are fixed with of lift set up relatively, are equipped with a plurality of healds on the cantilever, even there is lifting drive mechanism on one of them lift epaxial.
Furthermore, the lifting driving mechanism comprises a power box and a connecting rod, a transmission shaft, a swing rod and an input assembly used for driving the transmission shaft to rotate are arranged in the power box, a cam is fixed on the transmission shaft, a rod body of the swing rod is rotatably connected with the power box, a return spring is arranged between one end of the swing rod and the power box, the other end of the swing rod is rotatably connected with one end of the connecting rod, a roller attached to the periphery of the cam is arranged on the swing rod, and the other end of the connecting rod is rotatably connected with one of the lifting shafts.
Furthermore, the input assembly comprises an input shaft which is rotatably connected to the power box, an input gear is fixed on the input shaft, and a transmission gear which is meshed with the input gear is arranged on the transmission shaft.
The utility model has the advantages that: through the arrangement of the serging device independent of the heald frame, the serging device adopts two lifting shafts for hanging the heald pieces to simulate the heald frame, and therefore warp yarns at the edge part can be independently layered and opened to complete weft yarn occlusion, and therefore the serging of the fabric is achieved.

description of the reference symbols
The lifting mechanism comprises a lifting shaft 1, a rack 2, a gear 3, a cantilever 4, a heddle 5, a connecting rod 6, a swing rod 7, an input, a gear 8, a transmission gear 9, a cam 10, a return spring 11 and a roller 12.
Detailed Description
The present invention will be described in further detail with reference to examples.
The present embodiment provides a multifunctional cam independent lockrand, as shown in fig. 1 and 2, comprising a frame and a lifting driving mechanism. Two lifting shafts 1 are symmetrically arranged on the rack through linear bearings, racks 2 are arranged on the lifting shafts 1, a gear 3 which is positioned between the two racks 2 and is meshed with the two racks 2 is arranged on the rack, a cantilever 4 is fixed on the lifting shafts 1, a plurality of heald blades 5 are arranged on the cantilever 4, and one lifting shaft 1 is connected with a lifting driving mechanism.
The lifting driving mechanism of the embodiment comprises a power box and a connecting rod 6, an input shaft, a transmission shaft and a swing rod 7 are arranged in the power box, an input gear 8 is fixed on the input shaft, and a transmission gear 9 meshed with the input gear 8 is arranged on the transmission shaft. The transmission shaft is still fixed with cam 10, the body of rod and the headstock of pendulum rod 7 rotate to be connected, is equipped with between the one end of pendulum rod 7 and the headstock and replys spring 11, and the other end of pendulum rod 7 rotates with the one end of connecting rod 6 to be connected, be equipped with the gyro wheel 12 with cam 10 periphery laminating on the pendulum rod 7, the other end of connecting rod 6 rotates with one of them lift axle 1 to be connected.
The operation principle of the device of the embodiment is as follows:
power is input through an input shaft and then is transmitted to a cam 10 through an input gear 8, a transmission gear 9 and a transmission shaft in sequence, the far end and the near end of the cam 10 are in contact with a swing rod 7 alternately in the rotating process of the cam 10, one end, connected with a connecting rod 6, of the swing rod 7 swings up and down under the cooperation of a return spring 11, the swing of the swing rod 7 achieves lifting of a left lifting shaft 1 in the drawing 1 through the connecting rod 6, and lifting of the left lifting shaft 1 drives lifting of a right lifting shaft 1 in the drawing 1 through a gear 3. The two lifting shafts 1 are lifted in a staggered way, so that the healds 5 on the two swing arms can be opened and occluded as the healds 5 on the heald frame.
When the device is used, the serging device is arranged on one side of the tail end of a heald frame, warp yarns are threaded on the serging device heald 5 like the heald frame heald 5, when two lifting shafts 1 are in a staggered state (namely one is higher and the other is lower), the warp yarns are opened in a layered mode, weft yarns are fed at the moment, and when the two lifting shafts 1 are in the same high state, the warp yarns are meshed with the input weft yarns to realize serging.
The above embodiments are only used for explaining the concept of the utility model, and not for limiting the protection of the utility model, and any insubstantial modifications of the utility model using this concept shall fall within the scope of the utility model.
