Description

Technical Field

[0002] Metal wire roving is a special material used in the national defense and military fields. Currently, existing special friction spinning machines consist of a feeding mechanism, carding, cohesion twisting and winding parts. The main shortcomings of the existing technology are: there is no drafting adjustment device at the core yarn feeding inlet of the dust cage, so the thickness of the metal wire cannot be adjusted and it cannot adapt to the twisting of special rovings of various specifications. When the dust cage is in operation, the metal wire cannot be wrapped into shape, and the slippage coefficient increases significantly, resulting in insufficient twist of the twisted special roving, which greatly affects the quality of the product. The purpose of this utility model is to design a special friction spinning machine with metal wire drawing to solve the shortcomings of the existing technology. Utility Model Content

Detailed Implementation

[0013] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0014] A special friction spinning machine for drawing metal wire includes a support frame 5 and a feeding mechanism 1, a dust cage friction twisting mechanism 2, and a second traction mechanism 6 arranged sequentially from left to right on the support frame 5. The feeding mechanism 1, the dust cage friction twisting mechanism 2, and the second traction mechanism 6 are arranged on the horizontal base plate of the support frame 5. The machine also includes a combing mechanism 3, which is arranged on the side plate of the support frame 5 and corresponds to the position of the dust cage friction twisting mechanism 2. The machine also includes a traction mechanism 4, which is arranged on the upper part of the support frame 5.

[0015] The feeding mechanism 1 includes a first support 11 and a second support 12 from left to right. A first twisting roller 111 and a second twisting roller 112 are respectively provided on the first support 11 and the second support 12. It also includes a first reduction motor 113 and a second reduction motor 114 respectively provided on the first and second supports 11 and 12. The first reduction motor 113 and the second reduction motor 114 drive the first and second twisting rollers 111 and 112 to rotate.

[0016] The dust cage friction twisting mechanism 2 includes a fifth support 29, and two parallel and symmetrically arranged dust cages 24 are arranged on the second support 29. The dust cages 24 are driven to rotate in opposite directions by a synchronous belt 22, a synchronous pulley 23 and a first motor 21. A twisting gear 25 is installed at one end of the dust cage 24 near the feeding mechanism 1. The radius of the twisting gear 25 is slightly larger than that of the dust cage 24. The traction mechanism 4 includes a fourth bracket 41, which is located on the upper part of the support frame 5. A traction roller 42 and a pressure roller 43 are arranged parallel to each other on the fourth bracket 41, with the traction roller 42 located below the pressure roller 43. The combing mechanism 3 is mounted on the support frame 5 and is positioned corresponding to the dust cage friction twisting mechanism 2. The combing mechanism 3 includes a third support 31 and a combing net 32, a drive shaft 33, a positioning wheel 62 and a second motor 36 mounted on the third support 31. The second traction mechanism 6 includes a sixth bracket 64 and a traction positioning twisting roller 61 mounted on the sixth bracket 64. A third reduction motor 63 is also mounted on the sixth bracket 64 to drive the traction positioning twisting roller 61 to rotate.

[0017] Let's look at the specific workflow of this embodiment: First, the metal wire is passed through the feeding mechanism 1 and the dust cage friction twisting mechanism 2 in sequence, and then through the positioning wheel 62 and the traction positioning twisting roller 61, and through the middle of the traction roller 42 and the pressure roller 43, and the fuzzy thread is inserted from the rear of the combing mechanism 3. When the traction mechanism 4 is activated, the traction roller 42 and the pressure roller 43 pull the metal wire to move. The traction speed of the traction mechanism 4 is synchronized with the speed of the second reduction motor 112 and the third reduction motor 63. The speed of the second reduction motor 112 is greater than the speed of the first reduction motor 111, thereby ensuring that the metal wire can be pulled thin when it enters the dust cage friction twisting mechanism 2. When the combing mechanism 3 is turned on, the second motor 36 of the combing mechanism 3 drives the feather yarn to move through the transmission shaft 33. After the feather yarn is crushed in the combing mechanism 3, it is blown towards the dust cage friction twisting mechanism 2 through the combing net 32. The dust cage 24 is driven to rotate in opposite directions by the synchronous belt 22, the synchronous pulley 23 and the first motor 21. The end of the dust cage 24 away from the feeding mechanism 1 is connected to the air guide pipe 26. The air guide pipe 26 creates a negative pressure inside the dust cage 24 through the fan. At this time, the crushed hairs are wrapped around the metal wire in the dust cage friction twisting mechanism 2. Here, since the end of the dust cage 24 near the feeding mechanism 1 is equipped with a twisting gear 25 and the radius of the twisting gear 25 is slightly larger than that of the dust cage 24, the slippage coefficient of the metal wire in the dust cage friction twisting mechanism 2 is greatly reduced. As a result, the twisted roving is smooth, uniform and of excellent quality, and the twist of the special roving is greatly improved.

[0018] In addition to the above embodiments, this utility model may have other implementation methods; all technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by this utility model.
