Description

Technical Field

[0001] The invention relates to the technical field of weft knitting machine cleaning, and in particular to a dust removal and cleaning device for a weft knitting machine and a control method thereof. Background Art

[0002] A weft knitting machine is a knitting machine that uses yarn to weave weft knitted fabrics along the weft needles. According to the shape of the "needle bed", it can be divided into circular weft knitting machines and flat weft knitting machines. According to the number of needle beds, it can be divided into single-sided weft knitting machines and double-sided weft knitting machines. Circular weft knitting machines have many advantages, such as multiple loop forming systems, high speed, high output, fast pattern changes, good fabric quality, fewer processes and strong product adaptability, and therefore have developed rapidly.

[0003] Since the weft knitting machine itself processes yarn, a material that is prone to produce lint, lint or broken threads are easily accumulated on the needle cylinder during operation, which can easily cause wear of the needle cylinder in the long run. Currently, the most common cleaning method is to use a vacuum cleaner, which requires moving the position of the vacuum cleaner head to clean multiple positions. Not only is the cleaning efficiency very low, but the operation is also more troublesome. In addition, since the lint is extremely light, it is easy to float away when the vacuum cleaner is turned on for cleaning, causing pollution to the workshop environment. After the lint is taken out, it is mixed with some impurities and dust and is directly discarded, causing waste.

[0004] In view of the above problems, the present invention document proposes a dust removal and cleaning device for a weft knitting machine and a control method thereof. Summary of the invention

[0024] A control method for a dust removal and cleaning device of a weft knitting machine comprises the following steps:

[0025] S1. When the vacuum cleaner is running, the fluff generated by the weft knitting machine is sucked by the vacuum head, and the fluff enters the second net cylinder through the vacuum cleaner and the dust outlet pipe, and the fluff adheres to the liquid stored in the second net cylinder, and the first electric push rod is retracted to expand the telescopic frame, and the telescopic frame drives the shell to move upward, so that the shell drives the vacuum head to move upward. Similarly, the first electric push rod is extended to shrink the telescopic frame, and the vacuum head moves downward. The reciprocating extension of the telescopic frame causes the vacuum head to move up and down to clean the fluff;

[0026] S2. When the telescopic frame moves upward, the connecting block drives the rope to move, causing the rope drum to rotate and drive the torsion spring to twist. When the telescopic frame moves downward, the torsion of the torsion spring resets and drives the rope drum to rotate again, causing the rope to reciprocate and keep the rope drum rotating reciprocatingly. The rope drum drives the rotating shaft to rotate, and the rotating shaft drives the stirring blade to rotate. The liquid in the stirring blade is in a flowing state to clean the fluff and separate the impurities from the fluff.

[0027] S3. During the spin-drying operation, the annular disk is controlled to move downward by the second electric push rod, so that the second net cylinder slides downward in the first net cylinder, so that the mesh holes of the first net cylinder and the second net cylinder correspond to each other. At this time, the liquid enters the interior of the outer cylinder, and when the second net cylinder is pressed down to a minimum, the first net cylinder moves downward, so that the third bevel gear is engaged with the second bevel gear, and as the shaft continues to rotate, the shaft also drives the first bevel gear to transmit to the second bevel gear, and the second bevel gear to transmit to the third bevel gear, and the third bevel gear drives the first net cylinder and the second net cylinder to rotate, so that the fluff is centrifuged to throw away the water, and then the cover is opened by the handle, and the fluff is taken out at this time.

[0028] Compared with the prior art, the present invention provides a dust removal and cleaning device for a weft knitting machine and a control method thereof, which have the following beneficial effects:

[0029] 1. The dust removal and cleaning device for a weft knitting machine and the control method thereof are provided with an adjustment component and a dust suction component. When the dust suction machine is running, the lint and impurities generated during the working process of the weft knitting machine can be sucked through the dust suction head, thereby improving the processing quality of the weft knitting machine. Secondly, through the telescopic movement of the first electric push rod, the first electric push rod drives the telescopic frame to perform telescopic movement, and the telescopic frame can drive the shell to perform reciprocating displacement movement through the fixed plate, so that the dust suction head can be displaced to perform dust removal operations, thereby increasing the dust removal area and cleaning efficiency, and meeting the demand for automatic displacement dust removal.

[0030] 2. The dust removal and cleaning device for a weft knitting machine and its control method are provided with a telescopic component, a pull rope driving component, a first net cylinder, a second net cylinder, a stirring component, a transmission component and a third bevel gear. When the adjusting component reciprocates up and down, the rope is reciprocated and stretched, and the rope can be wound up by a torsion spring, so that the rope disc can reciprocate, and the rotating shaft can drive the stirring blade to rotate, so that the stirring blade stirs the liquid and the fluff to flow, so that the fluff can be washed and cleaned by forward and reverse movements. After cleaning, the second electric push rod controls the annular disk to drive the The second net cylinder moves downward so that the mesh holes of the second net cylinder correspond to the mesh holes of the first net cylinder. At this time, the liquid can enter the outer cylinder. After the liquid is discharged, the second net cylinder drops to the lowest point and can drive the first net cylinder to move downward so that the third bevel gear is meshed with the second bevel gear. At this time, the rotating shaft can drive the first bevel gear and the second bevel gear to transmit, and the second bevel gear and the third bevel gear to transmit, so that the first net cylinder and the second net cylinder rotate, and the water in the fluff can be thrown away by centrifugal force, thereby reducing the water content, facilitating the cleaning and impurity removal of the fluff, and thus facilitating the subsequent recycling operation.

[0031] 3. The dust removal and cleaning device for a weft knitting machine and the control method thereof are provided with a pull rope drive assembly, a first net cylinder, a second net cylinder, a transmission assembly and a third bevel tooth. After the mesh holes of the first net cylinder and the second net cylinder correspond, the liquid is discharged, and by continuously pressing down, the second net cylinder drives the third bevel tooth to engage with the second bevel tooth. Since the telescopic assembly reciprocates up and down and can cooperate with the torsion spring to realize the reciprocating forward and reverse motion of the rope drum, the rotating shaft drives the first bevel tooth and the second bevel tooth to transmit, and the second net cylinder is driven by the third bevel tooth to centrifugally throw out water. After the fluff is washed with water and the water is separated, the specific gravity of the fluff is increased, which is conducive to the subsequent cleaning of the fluff out of the second net cylinder, and prevents the fluff from being easily dispersed in the air again due to its light specific gravity, causing secondary pollution to the working environment.

[0051] In this embodiment, when the adjusting component 103 reciprocates up and down, the rope 2051 is reciprocated and stretched, and the rope 2051 can be wound up by the torsion spring 2053, so that the rope drum 2052 can reciprocate and rotate, and the rotating shaft 2081 can drive the stirring blade 2082 to rotate, so that the stirring blade 2082 stirs the liquid and the fluff to flow, so that the fluff can be washed and cleaned by forward and reverse movements. After cleaning, the second electric push rod 2032 controls the annular disk 2023 to drive the second net cylinder 204 to move downward, so that the mesh of the second net cylinder 204 is aligned with the mesh of the first net cylinder 201. Correspondingly, at this time, the liquid can enter the outer cylinder 101. After the liquid is discharged, the second net cylinder 204 drops to the lowest point and can drive the first net cylinder 201 to move downward, so that the third bevel gear 211 is engaged with the second bevel gear 2093. At this time, the rotating shaft 2081 can drive the first bevel gear 210 and the second bevel gear 2093 to transmit, and the second bevel gear 2093 and the third bevel gear 211 to transmit, so that the first net cylinder 201 and the second net cylinder 204 are rotated, and the water in the fluff can be thrown away by centrifugal force, thereby reducing the water content, facilitating the cleaning and impurity removal of the fluff, and thus facilitating the subsequent recycling operation.

[0052] Example 3: Reference Figure 7 and Fig. 9 A dust removal and cleaning device for a weft knitting machine includes a transmission assembly 209, the transmission assembly 209 includes a second bevel tooth 2093, a rotating rod 2091 is fixedly connected to one side of the second bevel tooth 2093, the rotating rod 2091 is rotatably connected to a fourth bearing 2092, the fourth bearing 2092 is fixedly connected to a fixing seat 2094, the fixing seat 2094 is fixedly connected to the bottom wall of an outer cylinder 101, a third bevel tooth 211 is fixedly connected to the lower side of the first net cylinder 201, a stirring assembly 208 is provided through the outer cylinder 101, the first net cylinder 201 and the second net cylinder 204, a rotating shaft 2081 in the stirring assembly 208 is fixedly connected to a first bevel tooth 210, and the first bevel tooth 210 is meshed with the second bevel tooth 2093 of the transmission assembly 209;

[0053] The rope drive assembly 205 includes a rope drum 2052, a torsion spring 2053 is fixedly connected to the top of the rope drum 2052, the torsion spring 2053 is fixedly connected to the third bearing 2083 at the bottom, a rope 2051 is wrapped around the rope drum 2052, the end of the rope 2051 away from the rope drum 2052 is fixedly connected to the connecting block 2054, the rope 2051 passes around the guide wheel 2055, and the guide wheel 2055 is fixedly connected to the movable plate 1021.

[0054] In this embodiment: after the mesh holes of the first net cylinder 201 and the second net cylinder 204 correspond to each other, the liquid is discharged, and by continuously pressing down, the second net cylinder 204 drives the third bevel tooth 211 to mesh with the second bevel tooth 2093. Since the telescopic component 203 reciprocates up and down, it can cooperate with the torsion spring 2053 to realize the reciprocating forward and reverse motion of the rope drum 2052, so that the rotating shaft 2081 drives the first bevel tooth 210 and the second bevel tooth 2093 to transmit, and the second net cylinder 204 is driven by the third bevel tooth 211 to centrifugally throw out water. After the fluff is washed with water and separated from the water, the specific gravity of the fluff is increased, which is conducive to the subsequent cleaning of the fluff out of the second net cylinder 204, and prevents the fluff from being light in specific gravity and easily floating in the air again, causing secondary pollution to the working environment.

[0055] A control method for a dust removal and cleaning device of a weft knitting machine comprises the following steps:

[0056] S1. When the vacuum cleaner 1051 is operated, the fluff generated by the weft knitting machine is sucked by the vacuum head 1056, and the fluff enters the second net cylinder 204 through the vacuum cleaner 1051 and the dust outlet pipe 1055, and the fluff adheres to the liquid stored in the second net cylinder 204, and the first electric push rod 1033 is operated to retract, so that the telescopic frame 1031 is unfolded, and the telescopic frame 1031 drives the shell 1053 to move upward, so that the shell 1053 drives the vacuum head 1056 to move upward. Similarly, the first electric push rod 1033 is extended to shrink the telescopic frame 1031, and the vacuum head 1056 moves downward. Through the reciprocating extension and contraction of the telescopic frame 1031, the vacuum head 1056 moves up and down to clean the fluff;

[0057] S2. When the telescopic frame 1031 moves upward, the connecting block 2054 drives the rope 2051 to move, so that the rope drum 2052 rotates and drives the torsion spring 2053 to twist. When the telescopic frame 1031 moves downward, the torsion force of the torsion spring 2053 is reset and drives the rope drum 2052 to rotate again, so that the rope 2051 reciprocates and keeps the rope drum 2052 reciprocating. The rope drum 2052 drives the rotating shaft 2081 to rotate, and the rotating shaft 2081 drives the stirring blade 2082 to rotate. The liquid in the stirring blade 2082 is in a flowing state to clean the fluff and separate the impurities from the fluff.

[0058] S3. During the spin-drying operation, the annular disk 2023 is controlled to move downward by the second electric push rod 2032, so that the second net cylinder 204 slides downward in the first net cylinder 201, so that the meshes of the first net cylinder 201 and the second net cylinder 204 correspond to each other. At this time, the liquid enters the interior of the outer cylinder 101, and when the second net cylinder 204 is pressed down to a minimum, the first net cylinder 201 moves downward, so that the third bevel gear 211 is engaged with the second bevel gear 2093, and as the rotating shaft 2081 continues to rotate, the rotating shaft 2081 also drives the first bevel gear 210 and the second bevel gear 2093 to transmit, and the second bevel gear 2093 and the third bevel gear 211 to transmit, and the third bevel gear 211 drives the first net cylinder 201 and the second net cylinder 204 to rotate, so that the fluff is centrifuged to spin off the water, and then the cover body 2021 is opened by the handle, and the fluff is taken out.

The telescopic frame (1031) drives the shell (1053) to move upward, so that the shell (1053) drives the vacuum head (1056) to move upward. Similarly, the first electric push rod (1033) is extended, so that the telescopic frame (1031) is contracted, and the vacuum head (1056) moves downward.
