[0002] A flower loom is a loom with jacquard equipment that can weave patterns on fabrics. As an important equipment in the modern textile industry, the jacquard knitting machine produces a variety of exquisite knitwear with its unique technology. However, this efficient production process is also accompanied by a problem that cannot be ignored - the generation of fiber dander. During the operation of the jacquard knitting machine, the fiber raw materials will inevitably produce fine fiber dander after weaving and stretching by the machine. These danders not only adhere to various parts of the machine, but also drift into the production environment, which has a certain impact on the working environment and product quality. The presence of a large amount of fiber dander first brings certain health risks to the operators. Working in such an environment for a long time, workers may inhale these tiny fibers, which may cause potential harm to the respiratory system. Secondly, the dander attached to the knitwear will affect the appearance and quality of the product and reduce market competitiveness.

[0003] Existing jacquard knitting machines use fan blowing and mobile dust collection devices to collect floating fiber lint. However, a large amount of fiber lint will adhere to and be entrained on the surface and in the gaps of the finished knitted fabric and cannot be cleaned.

DETAILED DESCRIPTION

[0031] The following describes two implementation modes of the present application in detail with reference to the accompanying drawings.

[0032] The first implementation method:

[0033] Figure 1-8 A jacquard knitting machine with a self-cleaning winding mechanism is shown, comprising a knitting machine body 1; a winding mechanism 2 is provided at the lower part of the knitting machine body 1, the winding mechanism 2 comprises a cleaning box 3 and a winding roller 4 arranged at the rear side of the cleaning box 3 and connected to a driving motor, and a knitted fabric 5 passing through the cleaning box 3 is wound around the winding roller 4;

[0034] A first cleaning component 6 and a second cleaning component 7 are provided in the cleaning box 3. The first cleaning component 6 includes a negative pressure suction cylinder 12, and a blow pipe 15 abutting against the knitted fabric 5 is provided below the negative pressure suction cylinder 12. The negative pressure suction cylinder 12 is provided with an arc cover 1201 on the side facing the knitted fabric 5. A suction gap 1202 is opened in the middle of the arc cover 1201, and a cutting knife 13 abuts against the inner side of the arc cover 1201, and the cutting knife 13 is connected to a first motor 14 that drives it to rotate; the negative pressure suction cylinder 12 is connected to an external negative pressure vacuum cleaner, and the blow pipe 15 is connected to an external air source; the upper end of the first cleaning component 6 is fixedly connected to the top end of the cleaning box 3 through a fixing frame 8, the second cleaning component 7 has the same structure as the first cleaning component 6 and is centrally symmetrically arranged, and the second cleaning component 7 is connected to the top end of the cleaning box 3 through an electric telescopic rod 9.

[0035] For details, please refer to Figure 8 When the winding roller 4 rotates to wind the knitted fabric 5, the external negative pressure vacuum cleaner and the air source are started, and the electric telescopic rod 9 is started. The electric telescopic rod 9 drives the second cleaning component 7 to move downward, and the second cleaning component 7 squeezes and tensions the knitted fabric 5. At the same time, as the knitted fabric 5 passes through the first cleaning component 6 and the second cleaning component 7, the blowing pipe 15 of the first cleaning component 6 abuts against the lower end surface of the knitted fabric 5, and the blowing pipe 15 of the second cleaning component 7 abuts against the upper end surface of the knitted fabric 5. The negative pressure of the first cleaning component 6 and the second cleaning component 7 The pressure suction cylinder 12 performs negative pressure suction on the surface fiber hair and thread ends of the knitted fabric 5 through the suction gap 1202 of the arc-shaped cover 1201, and at the same time, the airflow blown by the blow pipe 15 blows the knitted fabric on the opposite side of the suction gap 1202, so that the thread ends and fiber hair can enter the arc-shaped cover 1201 more easily. At the same time, the first motor 14 drives the cutting knife 13 to make a circular motion in the arc-shaped cover 1201, and rotates and cuts the fiber hair and thread ends. The cut thread ends and fiber hair are better sucked by negative pressure, thereby realizing efficient cleaning of the upper and lower end surfaces of the knitted fabric 5.

[0036] Compared with the traditional jacquard knitting machine, the present invention uses the relatively arranged negative pressure suction cylinder 12 and the blowing tube 15. When cleaning the knitted fabric, the cooperation of the two methods of blowing airflow and negative pressure suction makes it easier for the fiber hair and thread ends adhered to the surface of the knitted fabric 5 to enter the arc cover 1201, and then the thread ends and fiber hair adhered to the knitted fabric 5 are cut by the rotating cutting knife 13, so as to improve the cleaning and collection effect and avoid the thread ends and fiber hair remaining on the fabric roll, which affects the subsequent winding and transportation; in addition, the second cleaning component 7 is driven by the electric telescopic rod 9 to extrude and tension the knitted fabric 5, so that the knitted fabric 5 has a better fitting effect with the blowing tube 15, thereby improving the blowing and suction effect on the fiber hair and thread ends.

[0037] See also Figure 3 and Figure 5 The negative pressure suction cylinder 12 is a strip-shaped hollow box structure arranged along the longitudinal direction of the knitted fabric 5, the arc cover 1201 is an arc-shaped strip with a semicircular cross-section, and the suction gap 1202 is a rectangular opening.

[0038] Specifically, when the knitted fabric 5 contacts the negative pressure suction cylinder 12, the negative pressure suction force of the negative pressure suction cylinder 12 better adsorbs the knitted fabric 5 on the outside of the suction gap 1202, thereby improving the negative pressure suction and collection effect of fiber hair and thread ends.

[0039] See also Figure 5 A support frame 1203 is provided on the side of the negative pressure suction cylinder 12 away from the arc cover 1201, and a lifting frame 16 slidably connected to the support frame 1203 is nested inside the support frame 1203, and the blowing pipe 15 is installed on the inner side of the lifting frame 16, and the lifting frame 16 passes through the support frame 1203 and is threadedly connected with an adjusting screw 17.

[0040] Specifically, by screwing the adjusting screw 17, the adjusting screw 17 drives the lifting frame 16 to slide along the support frame 1203, and the lifting frame 16 drives the inner blowing tube 15 to approach or move away from the arc cover 1201, thereby adapting to knitted fabrics 5 of different thicknesses, ensuring the guiding and clamping effect of the blowing tube 15 and the arc cover 1201 on the knitted fabric 5.

[0041] See also Figure 3 The electric telescopic rod 9 is connected to the second cleaning component 7 via a spring telescopic rod 10 , and a pressure sensor 11 is installed in the spring telescopic rod 10 .

[0042] Specifically, the spring telescopic rod 10 is a sleeve-type telescopic rod, which includes a sleeve fixedly connected to the movable end of the electric telescopic rod 9 and a sliding rod slidably nested in the sleeve, the lower end of the sliding rod is fixedly connected to the negative pressure suction cylinder 12, and the sliding rod abuts against a spring nested in the sleeve; the pressure sensor 11 is installed between the sliding rod and the top end of the sleeve; when monitoring the tension of the knitted fabric 5, the knitted fabric 5 abuts against the blow pipe 15 of the second cleaning component 7, and the knitted fabric 5 squeezes the negative pressure suction cylinder 12 through the blow pipe 15, and the negative pressure suction cylinder 12 squeezes the sliding rod, and the sliding rod squeezes the pressure sensor 1 installed in the sleeve, thereby realizing the tension monitoring of the knitted fabric 5.

[0043] See also Figure 4 and Figure 6 The cutting knife 13 is a strip-shaped cutting knife and is attached to the inner wall of the arc cover 1201. The end of the cutting knife 13 is fixedly connected with a handle 1301. The handle 1301 coincides with the radial line of the cross-sectional circle of the arc cover 1201. The handle 1301 is fixedly connected to the output shaft of the first motor 14.

[0044] Specifically, the output shaft of the first motor 14 drives the cutting knife 13 to make a circular motion along the inner wall of the arc cover 1201 through the knife handle 1301, cutting the thread ends and fiber hairs from the sides, which has a better cutting effect and reduces the root residues of the thread ends and fiber hairs.

[0045] See also Figure 4 and Figure 7 The blowing pipe 15 includes an inner tube 1501 fixedly connected to the inner wall of the lifting frame 16, the end of the inner tube 1501 is connected to the gas source through a pipeline, the inner tube 1501 is a hollow tube and the outer wall is provided with a row of inner air outlet holes 1503 equidistantly distributed along its axial direction, the outer side of the inner tube 1501 is sleeved with an outer rotating cylinder 1502 connected for rotation, and the outer wall of the outer rotating cylinder 1502 is provided with multiple rows of outgoing air holes 1504 distributed in a circular pattern.

[0046] Specifically, the moving knitted fabric 5 drives the outer rotating drum 1502 to rotate on the inner tube 1501 , and the outgoing air holes 1504 and the inner air holes 1503 are intermittently connected to generate pulse airflow, thereby improving the blowing effect of the spraying airflow on the knitted fabric 5 .

[0047] Second implementation method:

[0048] Figure 9-11 A jacquard knitting machine with a self-cleaning winding mechanism is shown. On the basis of the first embodiment, a traction roller 18 is provided on the left side of the first cleaning component 6. The traction roller 18 includes a load-bearing shaft 1801 fixedly connected to the inner wall of the cleaning box 3. The load-bearing shaft 1801 is sleeved with a radially arranged inner traction cylinder 1802 and an outer traction cylinder 1803. The outer walls of the inner traction cylinder 1802 and the outer traction cylinder 1803 are both fixedly connected with a spiral protrusion strip 1804, and the ends of both are connected to the same transmission shaft 20 through a transmission gear set 19. The transmission shaft 20 extends to the outer end of the cleaning box 3 and is fixedly connected to a second motor 21.

[0049] For details, please refer to Fig.11 The second motor 21 drives the inner traction cylinder 1802 and the outer traction cylinder 1803 to rotate through the transmission shaft 20 and the transmission gear set 19, and the inner traction cylinder 1802 pulls the knitted fabric 5 longitudinally from the middle to the inside, and at the same time, the outer traction cylinder 1803 pulls the knitted fabric 5 longitudinally from the middle to the outside, thereby realizing the longitudinal pulling of the knitted fabric 5 from the center to both sides, expanding the gap between the warp and weft of the knitted fabric 5, making it easier for the thread ends and fiber hairs wrapped in the knitted fabric 5 to be pushed out by the jet airflow and negative pressure suction, thereby improving the cleaning effect of the knitted fabric 5. In addition, the blowing tube 15 of the second cleaning component 7 squeezes the knitted fabric 5, and the two work together to make the knitted fabric 5 looser, and clean the thread ends and fiber hairs, reducing the residue of thread ends and fiber hairs.

[0050] In this embodiment, the spiral protrusion strip 1804 is made of rubber material.

[0051] Specifically, the spiral protrusion strip 1804 has a better pulling effect on the knitted fabric 5 when rotating.

[0052] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
