Abstract
The utility model provides a heald lifting device of a shuttleless loom. The heald lifting device comprises a chain, wherein the outer side of the chain is shaped like a sine wave; the chain is wound on a pattern chain hub to form a cam mechanism; the chain is in close fit with a tail bearing of a blade; a supporting block is arranged in the middle of the blade and is fixed on a blade supporting plate to form a lever mechanism; the head of the blade is connected with a heald frame; heddles pass through the heald frame; yarns pass through the heddles; the upper end of the heald frame is connected with a heald lifting spring; the heald lifting spring is connected with a support frame upwards. The heald lifting device has the beneficial effects that the heddles are convenient and fast to hang and the yarns are convenient and fast to thread and the operation is carried out concisely; the heald lifting spring is easy to install and dismantle; the device has high reliability and good stability; the parts are not easy to damage, so that normal operation of production can be ensured.
Description
Technical field
The utility model belongs to weaving and light industry special equipment field, is specifically related to a kind of heald lifting device of shuttleless loom.
Background technology
The heald lifting device of existing shuttleless loom, is connected with nylon regulating block between blade and heald frame pin, and blade moves up and down and drives heald frame upper and lower interleaved operation, the falling of the long spring control blade below blade; Heald frame is clamped with fixed head in both sides, guarantees to slide in the each comfortable fixed head open slot of heald frame, and intermediate support plate is installed simultaneously increases heald frame bulk strength.But make in this way, the one, when heald is hung on heald frame bar, when preparing threading yarn, first need the to dismantle fixed head of both sides, then also will, the dismounting of the black nylon fixed strip of heald frame both sides, could hang over heald on the upper and lower horizontal bar of heald frame, after putting on heald, then again the installation of dismounting is resetted, the structure of the fixed head of both sides and machine itself occupies very large space, makes threading yarn difficulty, operation inconvenience; The 2nd, in the time of blade high-speed cruising, drive heald frame to move up and down, after increasing yarn load on heald frame, all strength has all been placed on heald frame pin, and heald frame pin easily ruptures; The 3rd, harness threading spring is positioned at the machine back lower place, and installation and removal all need specific purpose tool, and the narrow space of operation, inconvenient operation.
Utility model content
The purpose of this utility model is to overcome the problem that prior art exists, and a kind of heald lifting device of shuttleless loom is provided.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of heald lifting device of shuttleless loom, comprise chain, described chain lateral surface is shaped as sine curve, and described chain is wrapped on pattern chain hub, described chain and blade tail bearing closely cooperate, in the middle of described blade, be provided with back-up block, described back-up block is fixed on blade support plate, and described blade head is connected with heald frame, on described heald frame, be installed with heald, yarn is by described heald, and described heald frame upper end is connected with harness threading spring, and described harness threading spring is upwards connected with bracing frame.
Preferably, in the middle of described heald frame, heald frame leading truck is installed, and described heald frame can be free to slide on described heald frame leading truck, described heald frame leading truck top connects support frame as described above.
The beneficial effects of the utility model are:
Adopt technical solutions of the utility model, hang heald and entry convenient and swiftly, operation is succinct, and harness threading spring is easy to installing/dismounting, and device reliability is high, good stability, and parts are not fragile, can guarantee the normal operation of production.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Number in the figure explanation: 1, chain, 2, pattern chain hub, 3, blade, 4, bearing, 5, back-up block, 6, blade support plate, 7, heald frame, 8, heald, 9, harness threading spring, 10, bracing frame, 11, heald frame leading truck.
The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
Shown in Fig. 1, a kind of heald lifting device of shuttleless loom, comprise chain 1, described chain 1 lateral surface is shaped as sine curve, described chain 1 is wrapped on pattern chain hub 2 and forms cam mechanism, described chain 1 closely cooperates with blade 3 tail bearings 4, in the middle of described blade 3, be provided with back-up block 5, described back-up block 5 is fixed on blade support plate 6 and forms leverage, described blade 3 heads are connected with heald frame 7, on described heald frame 7, be installed with heald 8, yarn is by described heald 8, described heald frame 7 upper ends are connected with harness threading spring 9, described harness threading spring 9 is upwards connected with bracing frame 10.
Preferably, in the middle of described heald frame 7, heald frame leading truck 11 is installed, and described heald frame 7 can be free to slide on described heald frame leading truck 11, described heald frame leading truck 11 tops connect support frames as described above 10.
Principle of the present utility model:
During work, the heald lifting device of shuttleless loom adopts chain 1, pattern chain hub 2 to drive blade 3 and heald frame 7 to move up and down.As shown in Figure 1, pattern chain hub 2 is connected mix proportion cam mechanism with chain 1, and on back-up block 5 and blade support plate 6 in the middle of blade 3, composition leverage, utilizes cam lever principle that blade is moved up and down; When chain 1 is in height point position time, blade tail bearing 4 is by jack-up, and bit subordinate fall, and then drive brown frame 7 to move downward; When chain 1 is in low dot location time, harness threading spring 9 pull-up heald frames 7 are also with cutting blade 3 to move upward, blade tail bearing 4 drops to chain 1 lower, thereby realize blade and heald frame pumps, heald 8 is through on heald frame 7, yarn is by heald 8, and heald frame 7 up and down reciprocatingly drives yarn to interweave up and down.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
