Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.

Referring to fig. 3, for the utility model discloses a tension adjusting device for doubling, draw the machine including first drawing and get the machine and set up in the second that first drawing gets the machine low reaches, the rotational speed of first drawing the machine is less than the rotational speed that the machine was drawn to the second, and the rotational speed that the machine was drawn to the first rotational speed that draws is 200 and gives other 220r/min, and the rotational speed that the machine was drawn to the second is 210 and gives other 230 r/min. Because the rotational speed of first machine of drawing is less than the rotational speed of second machine of drawing, can adjust the tension when controlling to draw more steadily, improve later stage doubling quality.

Referring to fig. 3 and 4, the first drawing machine includes a frame 1, and two parallel wire guide wheel frames 12 arranged along the length direction of the frame 1, wherein two ends of each wire guide wheel frame 12 are connected with support rods 11 for supporting the wire guide wheel frames 12, and the support rods 11 are arranged obliquely. The one end that bracing piece 11 kept away from line guide wheel frame 12 is connected with carousel 3, and carousel 3 rotates to be connected on support 1, is provided with the locating component who is used for fixed carousel 3 turned angle on support 1, and the one end that bracing piece 11 kept away from carousel 3 is provided with a plurality of confessions along the length direction equidistance interval of bracing piece 11 and crosses line guide wheel frame 12 male through-holes 6.

Referring to fig. 3 and 6, in the present embodiment, the positioning assembly includes a C-shaped mounting base 5 fixed on the bracket 1 by screws, and a pin 4 penetrating through the mounting base 5, and a plurality of pin holes 31 for inserting the pin 4 are provided on the circumferential side surface of the rotary disk 3 at equal intervals. The mounting base 5 comprises a first fixing plate 51 and a second fixing plate 52, wherein the first fixing plate 51 is parallel to the second fixing plate 52, and the second fixing plate 52 is close to the insertion end of the pin shaft 4. The first fixing plate 51 and the second fixing plate 52 are both provided with a yielding hole for the pin 4 to pass through. Two positioning columns 53 positioned between the first fixing plate 51 and the second fixing plate 52 are welded on the mounting seat 5, the positioning columns 53 are symmetrically arranged on two sides of the pin shaft 4, two limiting columns 41 are arranged on the circumferential side surface of the pin shaft 4 at equal intervals, a pressure spring 42 positioned between the limiting columns 41 and the first fixing plate 51 is sleeved on the pin shaft 4, and the distance between the two positioning columns 53 is greater than the outer diameter of the pressure spring 42. When the pin 4 is inserted into the pin hole 31 for positioning, the position-limiting post 41 abuts against the positioning post 53 to prevent the pin 4 from retreating and retreating from the pin hole 31, thereby ensuring the stability of the pin 4 in positioning.

Referring to fig. 3 and 5, when the distance between the two wire guide wheel frames 12 needs to be adjusted before production, the pin shaft 4 is rotated to enable the limiting column 41 not to abut against the positioning column 53, the pin shaft 4 is pulled back to enable the pin shaft 4 to withdraw from the pin hole 31, at the moment, the pressure spring 42 is compressed, and then the pin shaft 4 is rotated to enable the limiting column 41 to abut against the positioning column 53; then, rotating carousel 3 to appointed angle, rotating round pin axle 4 makes spacing post 41 no longer lean on reference column 53, and the elastic deformation is replied to compressed pressure spring 42, promotes round pin axle 4 forward for round pin axle 4 inserts corresponding bolt hole 31, can accomplish the location, convenient and fast.

Referring to fig. 5 and 6, in order to make the positioning column 53 and the limiting column 41 abut against each other more tightly, an annular first annular groove 7 is formed on the circumferential side surface of the positioning column 53, and an annular second annular groove 8 is also formed on the circumferential side surface of the limiting column 41. Through the cooperation of first ring channel 7 and second ring channel 8 for inlay between reference column 53 and the spacing post 41 card more closely, draw and get the machine operation and produce the vibration when reference column 53 can not produce relative rocking with spacing post 41, stable in structure.

The implementation principle of the embodiment is as follows: when the pin 4 is inserted into the pin hole 31 for positioning, the position-limiting post 41 abuts against the positioning post 53 to prevent the pin 4 from retreating and retreating from the pin hole 31, thereby ensuring the stability of the pin 4 in positioning.

When the distance between the two wire guide wheel frames 12 needs to be adjusted before production, the pin shaft 4 is rotated to ensure that the limiting column 41 does not abut against the positioning column 53 any more, the pin shaft 4 is pulled back to ensure that the pin shaft 4 is withdrawn from the bolt hole 31, at the moment, the pressure spring 42 is compressed, and then the pin shaft 4 is rotated to ensure that the limiting column 41 abuts against the positioning column 53; then, rotating carousel 3 to appointed angle, rotating round pin axle 4 makes spacing post 41 no longer lean on reference column 53, and the elastic deformation is replied to compressed pressure spring 42, promotes round pin axle 4 forward for round pin axle 4 inserts corresponding bolt hole 31, can accomplish the location, convenient and fast.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
