Description

Technical Field

[0001] This invention relates to the field of knitting technology, and more particularly to the knitting process of knitted fabrics. Background Technology

[0002] Knitting is a process that uses knitting needles to form loops of various raw materials and types of yarn, and then connects them to form knitted fabrics. Knitted fabrics are soft, have good wrinkle resistance and breathability, and have great extensibility and elasticity, making them comfortable to wear. In addition to clothing and decoration, knitted products can also be used in industry, agriculture, medical and health care, and national defense.

[0003] Yarn is the raw material for knitted fabrics. During the yarn preparation process, a lot of dust and lint will be generated on the surface of the yarn. In the current technology, most of them do not have a device to clean the yarn. This dust and lint will be released or remain in the knitted fabric during knitting, which will not only pollute the working environment and threaten the health of workers, but also affect the quality of the product. At the same time, since there are many different types of yarn, in order to avoid yarn shrinkage, the fabric needs to be set after knitting. However, the effect of setting after knitting is not good. During the fabric setting, the shrinkage of the yarn inside the fabric affects the smoothness of the fabric. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a knitting process for knitted fabrics. By setting up a cleaning mechanism and a rotating mechanism, the yarn can be cleaned to avoid dust affecting product quality. At the same time, it can reduce dust during knitting and avoid pollution to the working environment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The knitting process for knitted fabrics includes the following preparation steps:

[0007] S1. Loading the yarn: The yarn required for knitting the fabric is loaded onto the knitting machine, and the knitting process is carried out by the knitting machine.

[0008] S2. Yarn cleaning: Clean the dust adsorbed on the surface of the yarn before it enters the knitting machine to prevent dust from affecting the knitting quality.

[0009] S3, Pre-setting: The cleaned yarn passes through a steam setting machine, where steam is used to pre-set the shape of the yarn.

[0010] S4. Collect and sort the fabrics that have been knitted by the knitting machine, and sort the fabrics, including re-setting and drying.

[0011] The steam setting machine used in step S3 above includes a base, a fixed plate fixedly connected to the upper end of the base, a cleaning mechanism for cleaning yarn on the fixed plate, the cleaning mechanism including multiple cleaning tubes rotatably connected to the fixed plate, sponge rings on the inner walls of the multiple cleaning tubes, and a third gear fixedly sleeved on each of the multiple cleaning tubes, a sliding groove on the fixed plate, a rotating mechanism for rotating the cleaning tubes in the sliding groove, a dust suction chamber on the fixed plate, an adsorption mechanism for adsorbing dust in the dust suction chamber, a steam box fixedly connected to the upper end of the fixed plate, water inside the steam box, a heating coil fixedly connected to the inner wall of the steam box, a stirring mechanism for stirring the water inside the steam box, a cavity inside the steam box, a pumping mechanism for pumping liquid inside the steam box inside the cavity, and a driving mechanism for driving the pumping mechanism inside the cavity.

[0012] Preferably, the rotating mechanism includes a slider slidably connected in a groove, a rack that meshes with a third gear fixedly connected to the upper end of the slider, and a second reciprocating screw rotatably connected between the inner walls of both ends of the groove, the second reciprocating screw passing through the slider and engaging with it.

[0013] Preferably, the adsorption mechanism includes a drive rod rotatably connected to the inner wall of the dust collection chamber, a fan blade fixedly connected to the end of the drive rod, a filter screen fixedly connected to the inner wall of the dust collection chamber, a motor fixedly connected to the side wall of the fixed plate, the end of the output shaft of the motor fixedly connected to the end of the second reciprocating lead screw, and both the output shaft of the motor and the end of the drive rod are fixedly connected to a first transmission wheel, and the two first transmission wheels are connected by a first belt drive.

[0014] Preferably, the stirring mechanism includes a rotating rod rotatably connected between the inner walls of both ends of the steam box, and two sets of blades are fixedly connected to the side wall of the rotating rod.

[0015] Preferably, the pumping mechanism includes a piston slidably connected to the cavity, and two crossbars are fixedly connected to the side wall of the piston. The ends of the two crossbars away from the piston are jointly fixedly connected to a movable plate.

[0016] Preferably, the drive mechanism includes a first reciprocating screw rotatably connected to the inner wall of the cavity, the first reciprocating screw passing through and cooperating with a movable plate, a first gear fixedly connected to the end of the rotating rod, and a second gear meshing with the end of the first reciprocating screw.

[0017] Preferably, the ends of the second reciprocating screw and the rotating rod are both fixedly connected to a second transmission wheel, and the two second transmission wheels are connected by a second belt drive. The two side walls of the steam box are provided with through holes that cooperate with the cleaning pipe.

[0018] Preferably, a cover is provided at the dust suction chamber, and a one-way liquid inlet pipe is fixedly connected to the side wall of the steam box.

[0020] Compared with the prior art, the beneficial effects of this invention are as follows:

[0021] 1.

The reciprocating movement of the slider drives the rack to move back and forth, and the reciprocating movement of the rack drives the third gear that meshes with it to rotate, which drives the cleaning tube to rotate. The yarn passes through the cleaning tube, which can clean the yarn and prevent dust from affecting product quality. At the same time, it can reduce dust during knitting and avoid polluting the working environment.

[0022] 2. By setting up an adsorption mechanism, the second reciprocating screw rotates, and under the transmission of the first transmission wheel and the first belt, the drive rod rotates. The rotation of the drive rod drives the fan blades to rotate, thereby drawing dust from the dust collection hood into the dust collection chamber, realizing the adsorption of dust, avoiding dust pollution of the working environment, and also preventing dust from being adsorbed onto the yarn again.

[0023] 3. By setting up a steam box and a fixing plate, this device can shape the yarn, improve product quality, and clean the yarn at the same time, making the device more practical. Cleaning and shaping can be carried out simultaneously, which can reduce processing steps and greatly improve work efficiency.

[0024] 4. By setting up a pumping mechanism and a stirring mechanism, when water needs to be added to the steam box, the water pipe is connected to the one-way inlet pipe. Under the drive of the second transmission wheel and the second belt, the rotating rod rotates. Under the drive of the first gear and the second gear, the first reciprocating screw rotates, thereby driving the moving plate that cooperates with it to move back and forth, and then driving the piston to move back and forth in the cavity, pumping water into the steam box. At the same time, the rotation of the rotating rod drives the blade to rotate, thereby stirring the water and making the water heat evenly. Attached Figure Description
