Description

Technical Field

[0001] The present application relates to the technical field of warp knitting equipment, and in particular to a warp knitting machine. Background Art

[0002] A knitted fabric is formed by using one or several groups of parallel yarns to form loops on all the working needles of the machine fed in the warp direction at the same time. This method is called warp knitting, the fabric knitted by warp is called warp knitted fabric, and the machine that completes this warp knitting is called a warp knitting machine.

[0003] After completing the warp knitting, the warp knitting machine will output the warp knitted fabric from the discharge port. In order to facilitate the collection of the warp knitted fabric, a winding roller will be rotated on the discharge side of the warp knitting machine, and the output warp knitted fabric will be wound on the winding roller. However, as the number of layers of warp knitted fabric wound on the winding roller increases, the winding diameter of the winding roller becomes larger and larger while the speed of winding the warp knitted fabric remains unchanged. Therefore, the two sides of the warp knitted fabric between the winding roller and the discharge port of the warp knitting machine will be rolled and narrowed toward the middle, affecting the flatness of the warp knitted fabric wound on the winding roller.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-7 This application is described in further detail.

[0034] The present application embodiment discloses a warp knitting machine. Figure 1 The warp knitting machine includes a machine body 1 , a mounting seat 11 is fixedly connected to the discharge side of the machine body 1 , and the mounting seat 11 is a rectangular plate structure and extends in a direction away from the machine body 1 .

[0035] See also Figure 1 and Figure 2 A connecting seat 2 is provided on the mounting seat 11, and rollers 26 are rotatably connected to the four corners of the bottom of the connecting seat 2. A rolling groove 111 extending away from the machine body 1 is opened on the top of the mounting seat 11. The roller 26 is rollingly connected in the rolling groove 111, so that the connecting seat 2 can slide toward or away from the machine body 1.

[0036] See also Figure 2The connection seat 2 is rotatably connected with a receiving roller 12, and the warp knitted fabric produced by the machine body 1 enters from the top part of the receiving roller 12 and is wound around the outer peripheral side of the receiving roller 12 as the receiving roller 12 rotates. The connection seat 2 is provided with a driving member for driving the receiving roller 12 to rotate, and the driving member can be a motor.

[0037] See also Figure 2 and Figure 3 , a connecting groove extending in the vertical direction is provided on the top of the connecting seat 2, and a connecting column 21 of a long square columnar structure is provided on the connecting seat 2, and the connecting column 21 slides up and down in the connecting groove. The connecting column 21 includes a support bar 22 of a "U"-shaped structure that is integrally formed and located at the top, and the connecting column 21 is provided with a connecting roller 3, and the connecting roller 3 is rotatably connected to the support bar 22. The connecting column 21 is provided with an elastic driving member, and the elastic driving member is a driving spring 211, and the driving spring 211 is sleeved on the outer peripheral side of the connecting column 21, and one end of the driving spring 211 abuts against the support bar 22, and the other end abuts against the top of the connecting seat 2. When in use, the driving spring 211 is elastically released, pushing the support bar 22 to move upward, driving the connecting roller 3 to abut against the warp knitted fabric, so that the warp knitted fabric can be wound more smoothly on the receiving roller 12.

[0038] See also Figure 4 and Figure 5 The connecting roller 3 includes a first roller segment 31 and a second roller segment 32. The second roller segments 32 are coaxially and symmetrically arranged. The opposite sides of the second roller segments 32 are fixedly connected to the support bars 22 respectively. The first roller segment 31 is arranged between the two second roller segments 32, and the two ends of the first roller segment 31 are respectively fixedly connected with the first rotating shaft 311. The first rotating shaft 311 is respectively rotatably connected to the two second roller segments 32. The first roller segment 31 and the second roller segment 32 are coaxially arranged and have the same diameter.

[0039] See also Figure 5 and Figure 6 The second roller segment 32 is provided with a receiving groove 321 on the side facing the receiving roller 12, and the second roller segment 32 is provided with a smoothing wheel 33 in the displacement receiving groove 321. The two ends of the smoothing wheel 33 are fixedly connected with second rotating shafts 331, and the second rotating shafts 331 are rotatably connected to the side walls of the receiving groove 321 on both sides, and the second rotating shafts 331 are perpendicular to the second roller segment 32, and the outer peripheral side of the smoothing wheel 33 is in contact with the warp knitted fabric.

[0040] See also Figure 5 and Figure 6The connecting roller 3 is provided with a transmission assembly 5, which includes a transmission bevel gear 52 and a connecting bevel gear 51. The second roller segment 32 is provided with a transmission groove, and the first rotating shaft 311 and the second rotating shaft 331 extend into the transmission groove respectively. The transmission bevel gear 52 and the connecting bevel gear 51 are located in the transmission groove. The connecting bevel gear 51 is fixed on the second rotating shaft 331, and the transmission bevel gear 52 is fixed on the first rotating shaft 311. The transmission bevel gear 52 is meshed with the connecting bevel gear 51. When the receiving roller 12 rotates to wind up the warp knitted fabric, the first roller segment 31 rotates with the receiving roller 12. At this time, the transmission bevel gear 52 drives the smoothing wheel 33 to rotate through the connecting bevel gear 51, and the warp knitted fabric is smoothed away from the first roller segment 31, thereby improving the flatness of the warp knitted fabric wound on the receiving roller 12.

[0041] See also Figure 6 and Figure 7 A support plate 13 is fixedly connected to the top of the mounting seat 11 at a position away from the machine body 1, and a connecting rope 23 is slidably passed through the connecting seat 2. One end of the connecting rope 23 is fixed to the side of the supporting plate 13 close to the machine body 1, and the other end is wound and fixed in the connecting seat 2. When the number of layers of warp knitted fabric wound on the receiving roller 12 increases, the length of the next layer of warp knitted fabric wound by the receiving roller 12 increases. At this time, the winding speed of the receiving roller 12 is greater than the speed at which the machine body 1 produces the warp knitted fabric, and the warp knitted fabric between the receiving roller 12 and the machine body 1 is pulled. The connecting seat 2 is provided with a control component 4. When the number of layers of the warp knitted fabric wound on the receiving roller 12 increases, the connecting roller 3 drives the connecting column 21 to move downward. At this time, the control component 4 controls the connecting rope 23 to slide out of the connecting seat 2. The elastic force generated by the warp knitted fabric being pulled between the receiving roller 12 and the machine body 1 acts on the receiving roller 12, driving the connecting seat 2 to slide toward the machine body 1, so that the warp knitted fabric can return to the state before being pulled, thereby reducing the possibility of the warp knitted fabric being pulled and rolled up and narrowed.

[0042] See also Figure 2 and Figure 3The control assembly 4 includes a control board 41 and a control column 42. A control groove 24 is provided in the connection seat 2. The connection rope 23 extends into the control groove 24 away from the support plate 13. The connection seat 2 is fixedly connected with a mounting column 25 of a long cylindrical structure. The mounting column 25 is located in the control groove 24 and its extension direction is perpendicular to the connection roller 3. The control column 42 has multiple and evenly spaced circumferentially arranged on the mounting column 25. The mounting column 25 has multiple chute 253 evenly spaced circumferentially. The chute 253 corresponds to the control column 42 one by one and is slidably connected to the chute 253. The control column 42 is a long square columnar structure. The control board 41 is fixed to the end of the control column 42 away from the mounting column 25. The control board 41 is an arc-shaped plate-shaped structure with the arc-shaped convex side facing away from the mounting column 25. After the connecting rope 23 is wrapped around the arc-shaped convex side of the control plate 41, the end away from the support plate 13 is fixed on the wall of the control groove 24. When the connecting column 21 slides toward the mounting column 25, the distance between the control plate 41 and the mounting column 25 decreases. At this time, the connecting rope 23 is in a relaxed state, and the connecting seat 2 can slide toward the body 1. When the connecting seat 2 slides toward the body 1, the relaxed part of the connecting rope 23 is pulled out of the connecting seat 2.

[0043] See also Figure 2 and Figure 3 The mounting column 25 is provided with a sliding groove 254, which is connected with the sliding groove 253. The control column 42 passes through the sliding groove 253 and slides into the sliding groove 254, and the ends thereof abut against each other. The mounting column 25 is provided with a power column 251 that slides in the sliding groove 254. The mounting column 25 is provided with a control spring 422, which is installed in the sliding groove 254. One end of the control spring 422 abuts against the side of the power column 251 away from the control column 42, and the other end abuts against the wall of the sliding groove 254. The control column 42 is inclined to form a control surface 421 facing the power column 251 on the side away from the control board 41. The power column 251 slides on the control surface 421, pushing the control column 42 to slide outward from the mounting column 25, so that the length of the connecting rope 23 wound outside the control board 41 increases. In the initial state, the control spring 422 is elastically released, pushing the power column 251 toward the control column 42, so that the control column 42 slides outward from the mounting column 25. At this time, the distance between the control plate 41 and the mounting column 25 reaches a maximum value.

[0044] See also Figure 2 and Figure 3The mounting column 25 is provided with a mounting hole, which is connected to the sliding groove 254. The connecting column 21 slides up and down in the mounting hole. The side wall of the power column 251 facing the mounting hole is provided with a pushing groove 2511. The power column 251 is inclined to form a power surface 252 facing the mounting hole. The power surface 252 is a side groove wall of the pushing groove 2511. In the initial state, the connecting column 21 abuts against the power surface 252. When the connecting column 21 slides downward, the connecting column 21 slides on the power surface 252, pushing the power column 251 in the direction of the control spring 422, so that the power column 251 is away from the control surface 421. At this time, the control column 42 can slide into the mounting column 25.

[0045] The implementation principle of a warp knitting machine in the embodiment of the present application is:

[0046] During production, the body 1 outputs the warp knitted fabric, and the receiving roller 12 reels the warp knitted fabric. As the number of layers of the reeled warp knitted fabric increases, the connecting column 21 gradually moves downward, so that the power column 251 is away from the control surface 421, the connecting rope 23 enters a relaxed state, and the connecting seat 2 can move toward the body 1. The length of each layer of the reeled warp knitted fabric is continuously increased by the receiving roller 12, so that the reeling speed is greater than the output speed of the body 1. At this time, the reeling roller 12 and the body 1 pull the warp knitted fabric to generate a force to drive the connecting seat 2 to move toward the body 1, thereby reducing the pulling force on the warp knitted fabric between the receiving roller 12 and the body 1, and reducing the possibility of the warp knitted fabric between the receiving roller 12 and the body 1 being narrowed and reeled.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
