Abstract

The utility model belongs to a textile machinery spare part, in particular to an hollow grooved drum used for the bobbin winder, which comprises an outer drum, an inner drum and a flange with axle holes. It is characterized in that the outer drum and the inner drum form an hollow integrity with a support wing which shows a triangular connection in the inner surface of the inner drum along the outer drum curve. The utility model has following advantages. The hollow structure formed firmly by the inner drum and the outer drum is compact with good rigidity, no tangled yarns, low energy consumption and good heat dissipation, and the concentricity and circle perpendicularity are better than other relative machines. The utility model uses the half non-cutting manufacturing technique, which saves labor and materials, decrease the waste product rate, and increase the production efficiency. The utility model thoroughly overcomes the disadvantages in current grooved drums, reduces the manufacturing cost, and improves the production capacity.

Description

The bobbin-winding machine hollow grooved drum

Technical field

The utility model belongs to textile machinery accessories, relates in particular to a kind of bobbin-winding machine hollow grooved drum.

Background technology

All need on all kinds of yarn machines that the various raw materials that comprise silk, cotton, fiber crops, hair, nylon, acrylic etc. use when spinning realize the guide process by groove drum.Groove drum is the attrition component on the bobbin-winding machine, and the groove drum of high speed revolution very easily is worn when guide.Before the nineties, China's textile industry is mainly based on bakelite drum production.The early 1990s, developed metal drum successively, comprise the steel plate groove drum, surpass and mould groove drum, its resistance to abrasion improves greatly.At present, all adopt the steel plate groove drum on the novel bobbin winder both at home and abroad.Metal drum is distinguished by material and is had three classes: 1. skin-hard aluminum alloy groove drum and the super groove drum of moulding; 2. steel plate groove drum; 3. cast groove drum.Its light plate groove drum is wear-resisting, antistatic with it, can reduce significantly that yarn is overlapping, calcination and the sanding of yarn bar bar, advantage such as rub, and is accepted by market gradually.But,, greatly suppressed the widespread use of steel plate groove drum again because its manufacturing process complexity, manufacturing procedure are long.Steel plate groove drum structure exists obvious defects, i.e. the internal access slotware of the urceolus of drawing and press forming is affixed with inner core along the shape line welding on urceolus surface.In spot welding, when bonding, in order to cancel the remaining lining cement of abutting edge, need manual deburring, then make the groove drum flute surfaces rough, the groove drum groove twines yarn, the cylindrical shell easy deformation easily when using getting on the bus for the first time.

The utility model content

The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and provide a kind of and remove internal access slotware, compact conformation, good rigidly, do not twine yarn, less energy consumption, bobbin-winding machine hollow grooved drum that thermal diffusivity is good.

The utility model for achieving the above object, by the following technical solutions: a kind of bobbin-winding machine hollow grooved drum, the flange that comprises urceolus, inner core and tape spool hole, it is characterized in that: described urceolus and inner core connect into hollow integral by the braced wing affixed with it, and described braced wing is along urceolus curve trend captive joint triangular in shape on the inner core circumferential surface.

Described flange is provided with radiating groove.

Described braced wing shape is fan-shaped or saddle type.

The beneficial effects of the utility model: structure is by inner core and the affixed hollow structure that forms of urceolus.Compact conformation, good rigidly, not twine yarn, less energy consumption, thermal diffusivity good, and concentricity all is better than other like product with the circle squareness.Manufacturing process belongs to half does not have cutting, and saving of labor, material-saving, reject rate are low, the production efficiency height.When thoroughly having solved existing steel plate groove drum defective, reduced manufacturing cost, greatly improved production capacity.

The specific embodiment

Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.

Shown in Fig. 1-4, a kind of bobbin-winding machine hollow grooved drum, the flange 5 that comprises urceolus, inner core and tape spool hole 4, described urceolus 1 and inner core 2 connect into hollow integral by the braced wing affixed with it 3, described braced wing is along urceolus curve 6 trends captive joint triangular in shape on the inner core circumferential surface, the braced wing shape is fan-shaped or saddle type, and inside and outside tube forms with processes such as essence casting, punching presses respectively, by braced wing inner/outer tube is linked to be hollow integral.Form the space between urceolus and the inner core, cancellation internal access slotware to the burr on shape line and urceolus surface, is avoided groove drum to get on the bus for the first time and is twined yarn, the defective of cylindrical shell easy deformation when using easily in the minimizing processes.Flange is provided with radiating groove 7, can play the effect of heat radiation, balance and blowing.Owing to form air by-pass passage with the hollow cylinder body, when high-speed operation, can make the groove drum heat radiation, avoid the thickness of yarn inequality; When the processing radiating groove, can adjust the kinetic balance of groove drum simultaneously; When the groove drum high-speed operation, the silk hair on the yarn when radiating groove can be taken wind out of and will spin blows off.The flange of inner core one side and inner core one end also can adopt smart casting or additive method to make integral body, and braced wing is cast integral body simultaneously.During use, groove drum is contained on the bobbin-winding machine main shaft, fixes with the jackscrew (not shown).

The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.

Claims

1, a kind of bobbin-winding machine hollow grooved drum, the flange that comprises urceolus, inner core and tape spool hole, it is characterized in that: described urceolus and inner core connect into hollow integral by the braced wing affixed with it, and described braced wing is along urceolus curve trend captive joint triangular in shape on the inner core circumferential surface.

2, bobbin-winding machine hollow grooved drum according to claim 1, it is characterized in that: described flange is provided with radiating groove.
