Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a structure for preventing water from accumulating on a needle plate support. Background Art

[0002] The needle plate holder is one of the structures in the circular knitting machine. The scientific name of the circular knitting machine is the circular weft knitting machine (or circular weft knitting machine). The circular knitting machine has developed rapidly because of its multiple loop forming systems (called the number of yarn feeding paths or loop forming paths in enterprises, referred to as the number of paths), high speed, high output, fast shape change, good fabric quality, few processes, and strong product adaptability.

[0003] like Figure 1 As shown, the large circular knitting machine in the prior art includes a large tripod 1', a large plate 2' arranged below the large tripod 1', three middle support legs 3' detachably arranged between the large tripod 1' and the large plate 2' for supporting the lower end surface of the large tripod 1' to connect the large tripod 1' with the large plate 2', a mandrel guide sleeve 4' arranged on the large tripod 1', a mandrel sleeve 5' arranged in the mandrel guide sleeve 4', a large tripod mandrel 6' rotatably arranged in the mandrel sleeve 5', a middle core 7' arranged on the outer side of the lower end of the mandrel sleeve 5', and a lower end of the mandrel sleeve 5'. A middle kernel tray 8' whose end face is located below the middle kernel 7', a needle plate support 9' arranged on the large tripod core shaft 6' and whose lower end face is located below the middle kernel tray 8', a large plate gear 10' arranged on the large plate 2', an upper plate cut block 11' arranged on the outside of the middle kernel 7', a syringe 12' arranged on the outside of the needle plate support 9' and on the large plate gear 10' respectively, a lower horse seat 13' arranged on the large plate 2' and located above the large plate gear 10', and a lower circle cut block 14' arranged at the upper end of the lower horse seat 13' and located outside the syringe 12'.

[0004] When the needle plate support is rotating, in order to prevent the lint from adhering to the needle plate and causing the needle to get stuck, it is necessary to use a blowing device to blow out high-pressure gas to blow away the lint at the syringe, but the moisture contained in the high-pressure gas can easily enter the space between the center core and the needle plate tray, resulting in poor gas flowability between the center core and the needle plate tray, causing the moisture in the high-pressure gas to easily accumulate on the needle plate tray and form water accumulation, which can cause the accumulated water to leak to the lower end surface of the needle plate support or flow into the searchlight and or onto the cloth surface. Utility Model Content

[0005] The utility model aims to provide a structure for preventing water accumulation in a needle plate support seat in view of the defects and shortcomings of the prior art.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a structure for preventing water accumulation in a needle disk support, comprising a core shaft sleeve, a middle core arranged on the side end surface of the core shaft sleeve, a large core shaft rotatably arranged in the core shaft sleeve, and a needle disk support arranged at the lower end of the large core shaft and below the middle core for rotating with the large core shaft, and also comprising at least one flow tube arranged on the lower end surface of the needle disk support for supplying external air to enter between the middle core and the needle disk support when the needle disk support rotates so as to improve the gas flowability between the middle core and the needle seat tray, wherein the flow tube is an "L"-shaped tube, and the upper end of the flow tube is adjacent to the upper end of the needle disk support.

[0007] A further improvement is that: the middle core is provided with an air outlet nozzle for allowing air to flow outward after external air enters between the middle core and the needle plate support from the circulation pipe to improve gas circulation.

[0008] A further improvement is that an air intake filter is provided on the circulation tube for filtering fluff or impurities in the air before the external air passes through the circulation tube and enters between the center core and the needle plate support seat.

[0009] A further improvement is that an air outlet filter is provided on the air outlet nozzle to prevent external hair or impurities from entering between the middle core and the needle plate support seat through the air outlet nozzle.

[0010] A further improvement is that a breathable film is provided on the circulation tube for preventing moisture in the air from entering between the middle core and the needle disk support seat before the external air passes through the circulation tube and enters between the middle core and the needle disk support seat.

[0011] A further improvement is that the upper end surface of the needle tray holder is provided with a water-preventing device for discharging water outwards when water accumulates on the needle tray to prevent water from accumulating on the needle tray.

[0012] A further improvement is that the anti-water accumulation device includes a water accumulation groove opened on the upper end surface of the needle plate support for water accumulation, a connecting hole opened on the lower end of the needle plate support and connected to the water accumulation groove, and a drainage joint arranged on the needle plate support and located in the connecting hole for discharging water in the water accumulation groove to the outside when water accumulates on the water accumulation groove.

[0013] After adopting the above technical scheme, the beneficial effect of the utility model is as follows: when the needle disk support seat rotates with the core shaft of the large tripod, the needle disk support seat drives the circulation tube to change its position, so that the external air enters between the central core and the needle disk support seat from the circulation tube, so as to improve the gas flowability between the central core and the needle seat tray, balance the air pressure difference, and reduce the phenomenon of water accumulation on the needle disk tray to form water accumulation, which is not easy to cause the accumulated water to leak to the lower end surface of the needle disk support seat or flow into the searchlight and or the cloth surface.

[0014] Further effect: the air flow between the center core and the needle plate support is improved through the cooperation between the air outlet nozzle and the circulation tube, so as to balance the air pressure in the space.

[0015] Further effect: Since it is necessary to suppress the flying of lint in some parts of the workshop, the vehicle inspection environment needs to be humidified, resulting in an increase in the moisture content in the air. At this time, the breathable film can block the humid air, allowing dry gas to enter between the core and the needle plate support from the circulation pipe. BRIEF DESCRIPTION OF THE DRAWINGS
