Description

Technical Field

[0001] The invention relates to the technical field of hollow needle beds, in particular to a hollow needle bed for a textile warp knitting machine. Background Art

[0002] The method of knitting a fabric by feeding one or several groups of parallel yarns into all the working needles of the machine in the warp direction and forming loops at the same time is called warp knitting, and the fabric is called warp knitted fabric. The machine that completes this warp knitting is called a warp knitting machine. The warp knitting machine is mainly composed of a weaving mechanism, a bar slidable mechanism, a warp feeding mechanism, a pulling and winding mechanism, and a transmission mechanism.

[0003] The weaving mechanism of a textile warp knitting machine uses a hollow needle bed. Since the base of the hollow needle bed is a hollow structure, the temperature of the textile warp knitting machine will gradually increase during the weaving process. The temperature of the warp knitting machine will have a direct impact on the hollow needle bed. The hollow needle bed will expand when heated, which will cause deformation and cause the knitting needles to deviate. The stability of the needle spacing cannot be guaranteed, which affects the quality of subsequent weaving and greatly affects the weaving work efficiency, resulting in less than ideal results.

[0004] For this reason, a hollow needle bed for a textile warp knitting machine is proposed. Summary of the invention

[0005] The purpose of the present invention is to provide a hollow needle bed for a textile warp knitting machine, which drives a movable plate to move upward through the expansion of a corrugated airbag. At the same time, the movable plate squeezes the elliptical airbag so that the cold water in the elliptical airbag is discharged into the drain pipe through a telescopic tube, and finally is evenly sprayed on the inner wall of a cooling box through a nozzle, which can effectively cool the cooling box, thereby effectively improving its cooling effect, thereby effectively improving work efficiency.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A hollow needle bed for a textile warp knitting machine comprises a hollow needle bed body, the top of the hollow needle bed body is fixedly connected to a fixed frame, a needle slot plate is arranged in the fixed frame, knitting needles are evenly installed on one side of the needle slot plate, a groove is opened on the top of the needle slot plate, a plurality of cooling boxes are evenly placed in the inner cavity of the groove, the top of each group of the cooling boxes is threadedly connected to a threaded cover, one side of each group of the cooling boxes is fixedly connected to a connecting frame, a movable plate is slidably connected in each group of the connecting frames, a corrugated airbag is installed between each group of the movable plate and the bottom of the inner cavity of the adjacent connecting frame, a heat conducting plate is sleeved on the bottom of the needle slot plate, a heat conducting rod is evenly fixedly connected to the top of the heat conducting plate, the top of each group of the heat conducting rods penetrates the adjacent connecting frame and the corrugated airbag and extends to the adjacent corrugated airbag where a heat conducting rod is fixedly connected, and a spray mechanism is arranged on the top of the movable plate.

[0008] When the hollow needle bed body generates heat during operation, the heat will be transferred to the heat conducting rod through the heat conducting plate and the heat conducting rod. At this moment, the internal heating of the corrugated airbag can be realized. The gas in the corrugated airbag is ammonia, and the expansion coefficient of ammonia is relatively large. Therefore, the corrugated airbag can expand and drive the movable plate to move upward for subsequent work. The needle slot plate can be cooled by the cooling box, so that the corrugated airbag can be contracted and drive the movable plate to move downward for subsequent work.

[0009] Preferably, the spray mechanism includes an elliptical airbag, which is installed on the top of the movable plate, and the top of the elliptical airbag is fixedly connected to a horizontal plate, and the horizontal plate is fixedly connected to the cooling box, and a vertical plate is provided on the side of the elliptical airbag away from the cooling box, and the vertical plate is fixedly connected to the movable plate, and the vertical plate is slidably connected to the horizontal plate, and a water suction pipe is sleeved on the top of the elliptical airbag, and the other end of the water suction pipe passes through the horizontal plate and the cooling box and extends to the bottom of the inner cavity of the cooling box, and the bottom end of the elliptical airbag is sleeved with a telescopic tube, and the top of the telescopic tube is fixedly connected with a drain pipe, and the other end of the drain pipe passes through the horizontal plate and the cooling box and extends to the top of the inner cavity of the cooling box, and nozzles are evenly sleeved on the drain pipe, and an alarm mechanism is provided on the top of the cooling box away from the connecting frame.

[0010] When the movable plate moves upward, the movable plate squeezes the elliptical airbag so that the cold water in the elliptical airbag is discharged into the drain pipe through the telescopic tube, and finally sprayed evenly on the inner wall of the cooling box through the nozzle, which can effectively improve the cooling effect. When the movable plate moves downward, the elliptical airbag can expand to its initial state and suck the cold water in the cooling box into the elliptical airbag through the suction pipe, so as to achieve the purpose of storage, so as to facilitate subsequent spraying.

Two contact blocks are in contact with each other, and the two contact blocks are electrically connected to the alarm instrument together.

[0012] The floating block will float on the surface of the water in the cooling box. When the water in the cooling box gradually becomes less, the floating block will drive the connecting plate to move downward gradually through the push rod, and finally the connecting plate can drive the adjacent contact blocks to contact the contact blocks on the top of the cooling box.

[0014] By pulling the first pull rod upward, the first pull rod can drive the lower fixing plate to move upward to squeeze the second spring, so that the bottom end of the first pull rod can be moved out of the slot at the top of the bottom plate, thereby facilitating disassembly and assembly.

[0015] Preferably, a sliding rod is provided on the side of the vertical plate away from the elliptical airbag, the sliding rod is fixedly connected to the top of the movable plate, a vertical rod is slidably connected to the sliding rod, the vertical rod is fixedly connected to the top of the inner cavity of the connecting frame, a first spring is sleeved on the rod wall of the sliding rod, and both ends of the first spring are fixedly connected to the vertical rod and the movable plate.

[0025] 2. The floating block will float on the surface of the water in the cooling box. When the water in the cooling box gradually becomes less, the floating block will drive the connecting plate to move downward gradually through the push rod, and finally the connecting plate can drive the adjacent contact blocks to contact the contact blocks on the top of the cooling box.
