Description

Technical Field

[0001] The utility model relates to the technical field of computer flat knitting machines, in particular to a double-layer roller device of a computer flat knitting machine. Background Art

[0002] With the development of knitting technology, roller is a component used to pull the woven fabric, including active roller rod and passive roller rod, and its function is to pull down the woven fabric woven by the needle bed. In conventional double-layer rollers, rollers are usually used for pulling. The roller has two roller rollers. When running, the fabric woven by the needle plate is clamped between the two roller rollers. Since the surface of the two roller rollers is provided with anti-slip and anti-static rubber sleeves, the fabric can be firmly clamped between the two roller rollers. The roller uses a motor and a gear box to achieve face-to-face rotation, thereby driving the rubber sleeve on the surface of the roller to rotate. Under the action of friction, the fabric can be tightened and pulled out from under the needle plate at a uniform speed. However, the pulling of the fabric by the roller device is a common means of knitting flat knitting machines. When the garment is knitted, the garment not only includes the front and back garment pieces or sleeve pieces, but also includes the shoulder and collar parts. The conventional roller device can often only pull one type of part. For the garment, it is necessary to pull different parts to facilitate the weaving of the fabric. Utility Model Content

[0003] The technical problem to be solved by the embodiment of the utility model is to provide a double-layer roller device for a computerized flat knitting machine, which adopts an upper and lower single roller design to pull various parts of the garment, and can realize the respective tension control of the front and rear fabrics, thereby greatly improving the weaving of the fabric.

[0004] To achieve the above object, the utility model discloses a double-layer roller device of a computerized flat knitting machine, comprising a first roller mechanism and a second roller mechanism, wherein the first roller mechanism and the second roller mechanism are arranged on a frame up and down;

[0005] The first roller mechanism comprises a first roller and a first roller shaft, the first roller and the first roller shaft are in contact transmission, and the first roller is swingably connected to the frame;

[0006] The second roller mechanism comprises a second roller and a second roller shaft, the second roller and the second roller shaft are in contact transmission, and the second roller is swingably connected to the frame;

[0007] A linkage mechanism is arranged on the ends of the first roller and the second roller, so that the swing drive device drives the linkage mechanism to drive the first roller / second roller to swing left and right to contact the first roller shaft / second roller shaft, and drives the first roller / second roller to rotate through the rotation drive device.

[0008] Furthermore, the first roller and the second roller each include a main transmission shaft, a secondary transmission shaft, a belt, and a triangular bracket. The main transmission shaft is arranged at the bottom of the triangular bracket, the secondary transmission shaft is arranged at the top of the triangular bracket, and the belt is tensioned between the main transmission shaft and the secondary transmission shaft.

[0009] Furthermore, the bottom of the triangular bracket has a first recess, and the top of the triangular bracket has a second recess, so that the main transmission shaft cooperates with the first recess, and the auxiliary transmission shaft cooperates with the second recess.

[0010] Furthermore, an arc-shaped recess is provided on one side of the triangular bracket facing the first roller shaft / the second roller shaft, and the arc-shaped recess matches the outer circumference of the first roller shaft / the second roller shaft.

[0011] Furthermore, the first roller mechanism includes a third roller and a fourth roller, and the third roller and the fourth roller are arranged in parallel.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0024] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Embodiment 1:

[0026] Reference Figure 1 As shown, a double-layer roller device of a computer flat knitting machine includes a first roller mechanism 1 and a second roller mechanism 2. In this embodiment, a frame 3 is arranged below the front needle plate 4 and the rear needle plate 5. The first roller mechanism 1 and the second roller mechanism 2 are arranged on the frame 3 from top to bottom. After the fabric 6 is knitted by the knitting needles on the front needle plate 4 and the rear needle plate 5, it falls between the two needle plates, so that the first roller mechanism 1 and the second roller mechanism 2 pull the fallen fabric.

[0027] Reference Figure 1 , Figure 2 As shown, in this embodiment, the first roller mechanism 1 includes a first roller 11 and a first roller shaft 12, and the first roller 11 is in contact with the first roller shaft 12 for transmission. The second roller mechanism 2 includes a second roller 21 and a second roller shaft 22, and the second roller 21 is in contact with the second roller shaft 22 for transmission, wherein the first roller 11 and the first roller shaft 12 are relatively staggered with the second roller 21 and the second roller shaft 22.

[0028] Combination Figure 8As shown, further, the first roller 11 and the second roller 21 each include a main transmission shaft 101, a secondary transmission shaft 102, a belt 103, and a triangular bracket 104, the bottom of the triangular bracket 104 has a first recess 105, the top of the triangular bracket 104 has a second recess 106, the main transmission shaft 101 cooperates with the first recess 105, the secondary transmission shaft 102 cooperates with the second recess 106, the belt 103 is tensioned between the main transmission shaft 101 and the secondary transmission shaft 102, wherein the end of the main transmission shaft 101 is rotatably connected to the frame, and a rotation drive device is fixedly installed on the frame 3. In this embodiment, the rotation drive device preferably adopts a motor, so that the main transmission shaft 101 is driven by the rotation drive device to drive the belt 103 to rotate.

[0029] Furthermore, end covers are provided on the ends of the first roller 11 and the second roller 21, and a linkage mechanism is fixedly provided on the end covers. A swing driving device is also fixedly installed on the frame. In this embodiment, the linkage mechanism preferably adopts gears, and the swing driving device preferably adopts a motor, whose output shaft is fixedly provided with a driving gear meshing with the gear, so that the first roller 11 / the second roller 21 is driven to swing left and right through the swing driving device, thereby controlling the contact between the first roller 11 / the second roller 21 and the first roller shaft 12 / the second roller shaft 22.

[0030] Reference Figure 2 As shown, further, the height of the first roller 12 / second roller 22 is the same as the upper height of the first roller 11 / second roller 12, so when the first roller 11 / second roller 12 swings toward the first roller 12 / second roller 22 driven by the swing drive device, the upper part of the first roller 11 / second roller 12 contacts the first roller 12 / second roller 22.

[0031] Reference Figure 1 , Figure 2 During the specific operation, after the woven garment falls between the first roller 11 and the first roller 12 in the middle of the two needle plates, the first roller 11 is driven to swing to the right by the swing driving device, so that the upper part of the first roller 11 contacts the first roller 12 to clamp the garment, and then the belt 103 of the first roller 11 is driven to rotate by the rotation driving device, and the first roller 12 rotates with the downward pull of the garment, so as to pull the garment downward. When the pulled garment reaches the second roller 21 and the second roller 2 2, another swing driving device drives the second roller 21 to swing leftward, so that the upper part of the second roller 21 is in contact with the second roller shaft 22 to clamp the garment, and the belt of the second roller 21 is driven to rotate by the rotary driving device. The second roller shaft 22 rotates as the garment is pulled down, so that the first roller 11 and the second roller 21 are used to pull the front piece and the back piece of the garment respectively, so as to meet the pulling force of the front piece and the back piece of the garment and make the pulling force of the front piece and the back piece of the garment more uniform.

[0032] In addition, since the first roller 11 and the second roller 21 are independently controlled by the rotating drive device, the speed of the first roller 11 or the second roller 21 can be adjusted according to the tension requirement of the fabric, and the friction force between the first roller 11 or the second roller 21 and the fabric can be adjusted by the swinging drive device, thereby realizing respective tension control of the front and rear fabrics.

[0033] Reference Figure 3 , Figure 4 As shown, when weaving a single-sided fabric, the first roller 11 or the second roller 21 is driven by the swing drive device to swing to the left, so that the first roller 11 is separated from the first roller 12 or the second roller 21 is separated from the second roller 22, so that the fabric pieces can be pulled at a high position by the first roller 11 or the fabric pieces can be pulled at a low position by the first roller 11, thereby making the rollers more applicable.

[0034] Embodiment 2:

[0035] Reference Figure 5-Figure 8 As shown, the difference between this embodiment and embodiment 1 is that an arc-shaped recess 107 is provided on the side of the triangular bracket 104 facing the first roller 12 / second roller 22, and the arc-shaped recess 107 matches the outer periphery of the first roller 12 / second roller 22, and the height of the first roller 12 / second roller 22 is the same as the middle height of the first roller 11 / second roller 21, so that when the swing driving device drives the first roller 11 / second roller 21 to swing in the direction of the first roller 12 / second roller 22, the arc-shaped recess of the first roller 11 / second roller 21 contacts with a roller 12 / second roller 22, thereby greatly increasing the pulling force and friction force of the first roller 11 and the second roller 21 on the fabric, thereby significantly improving the quality of the front and back pieces of the fabric.

[0036] Embodiment three:

[0037] Reference Fig. 9 , Fig.10 As shown, the first roller mechanism 1 includes a third roller 13 and a fourth roller 14, and the third roller 13 and the fourth roller 14 are arranged in parallel. The difference between this embodiment and the first embodiment is that the first roller is replaced by the fourth roller 14, so that the third roller 13 and the fourth roller 14 are used to pull the fabric by synchronous movement, and the second roller mechanism 2 in this embodiment can be arranged in the manner of the first embodiment or the second embodiment.
