Description

On-machine fancy velvet cutting device, velvet cutting method and three-dimensional special loom

Technical Field

The invention belongs to the field of textile machinery manufacturing, and particularly relates to an on-machine pattern type velvet cutting device applied to a double-rapier double-weaving-opening high-rise velvet weaving machine.

Background

The velvet cutting equipment is divided into two types, one type is on-machine velvet cutting equipment, and the other type is off-machine velvet cutting equipment. The on-machine cut pile is the equipment integrating the cut pile device and the weaving machine, and the cut pile is finished while weaving. At present, the cut pile on the machine is only divided, namely a double-layer vertical pile fabric is divided from the middle to form two vertical pile fabrics. The under-machine cut pile is the cut pile of the pile fabric on a special cut pile machine after the pile fabric is fed on and off the loom. The under-machine velvet cutting equipment generally comprises a cutting device and a trimming device, wherein the cutting device cuts and separates the double-layer velvet fabric into two pieces of fabric, and the trimming device can trim relief patterns on the velvet fabric. The machine-cut velvet has the advantages that the upper base cloth and the lower base cloth are in a high-tension tensioning state, and the middle vertical velvet is in a vertical plump state and is suitable for cutting. If the fancy velvet cutting device on the manufacturing machine can be manufactured, two pieces of raised velvet fabrics with embossed patterns can be manufactured while the velvet is divided on the manufacturing machine.

The utility model discloses a utility model patent of a simple type machine cut fine hair device with publication number CN 213538259, is a machine cut fine hair for slim velvet. So-called thin velours, such as velvet, spun gold, georgette, etc., have a very short pile height, and when woven as a double-layer cloth on a loom, the total pile height is several millimeters. The working process of the technical scheme is as follows: "through setting up first driving motor, drive the screw rod and rotate to drive loading board and the velvet cutting blade below and reciprocate, be convenient for adjust its height, increase its application range, through setting up second driving motor, drive the velvet cutting blade horizontal migration, make the surface fabric can level and smooth cut the fine hair," reciprocating of the first motor that the scheme relates is "in advance" the regulation removal, and the purpose lets the cutter aim at the position, increases application range. The application range is to adapt to fabrics with different total pile heights, for example, the total pile height is 4mm, the center of the blade needs to be adjusted to be aligned with 2mm, the total pile height is 3mm, and the center of the blade needs to be adjusted to be aligned with 1.5 mm. Once in position, the fabric is no longer moved throughout the weaving and cutting process of this fabric, keeping the cutting knife stable in height. For thin short-staple fabrics, the stability of the operation of the cutting knife is very important during the cutting of the staple, so the second motor is a linear motor, and the load of the first driving motor is known to be quite heavy, and the second driving motor comprises a bearing plate with the same width as the cloth width, and a linear motor driving stator and a guide rail which are arranged on the bearing plate and have the same width as the cloth width.

The double-rapier double-weaving-opening high-raised-pile loom has the rapier distance of 65mm, the total height of woven pile can reach 60mm, and even if the loom is divided into two pieces, the pile height is enough to manufacture the embossed patterns. If the horizontal displacement of the velvet cutting blade is realized, the vertical displacement of the velvet cutting blade can be controlled according to a pattern program with a preset pattern, and then the relief pattern can be manufactured. It is clear that this requires a motor for vertical displacement that is lightly loaded and that can be moved quickly and flexibly. The double-vertical-displacement motor of the comparison document drives a frame structure with a large beam and heavy load through a double screw rod, so that the double-vertical-displacement motor is beneficial to stability, but is not suitable for flexible-change fancy cutting.

The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Example 1:

referring to fig. 1 and 2, the fancy cut pile device on the machine comprises a moving platform 1, wherein the moving platform 1 can horizontally reciprocate in the weft direction of the loom along a track 8, the speed and the rhythm of the horizontal reciprocating displacement are synchronous with the weaving rhythm of the loom, and a weft-direction partition marker is arranged on the track 8; the mobile platform 1 is provided with a vertical lifting module 2, and the vertical lifting module 2 is driven by a lifting module motor 6 to move up and down; the cutting blade 4 is arranged on the vertical lifting module 2 through a blade fixing frame 3, and the cutting blade 4 is driven to rotate through a cutting knife rotating motor 5; when the moving platform 1 horizontally moves in the weft direction of the weaving machine, the velvet cutting blade 4 can vertically move according to a preset pattern program, and when the moving platform 1 moves from the left side of the cloth width to the right side of the cloth width (or from the right side to the left side) and the cloth width is fully moved, the velvet cutting blade 4 can cut a full cloth width curve on the raised velvet surface of the double-layer fabric according to the pattern program, wherein the cutting depth is a weft distance of the fabric; after a weft is woven in the weaving machine, a coiling device of the weaving machine acts to drag the fabric to move forwards by a weft distance, the moving platform 1 moves from the right side of the fabric to the left side of the fabric (or from the left side to the right side) to move full fabric, and the velvet cutting blade 4 can cut a full fabric curve on the vertical velvet surface of the double-layer fabric according to the pattern plate program; the full-width curve is programmed into the pattern and pattern plate program in advance according to the required relief pattern.

Further, the on-machine fancy cut pile device of the embodiment further comprises a controller, the controller comprises an MCU chip, the MCU chip is internally provided with a memory with the pattern program, and the controller reads the pattern program and controls the vertical displacement height of the cut pile blade 4; a latitudinal partition position detector is arranged on the mobile platform 1, and the controller synchronously reads the current data of the pattern-type pattern-plate program according to a partition position signal sent by the latitudinal partition position detector; therefore, the moving platform 1 is executed in a reciprocating mode, the preset embossment pattern cutting is completed while the double-layer fabric is cut and separated, and the on-machine pattern cut velvet is achieved. Further, as shown in fig. 9, the zonal position detector comprises a first zonal position detector a and a second zonal position detector B, which are respectively disposed on two sides of the mobile platform 1, and the cut pile blade 4 is disposed between the first zonal position detector a and the second zonal position detector B.

And a distance E is formed between the first zonal position detector A and the second zonal position detector B and the velvet cutting blade 4, and when the mobile platform 1 moves rapidly, the distance is equivalent to the lead of a signal, so that the lead can be provided for the controller to process data and control the motor to move. When the moving platform 1 moves from the left side to the right side of the weaving machine, which is generally called a forward stroke, the first latitudinal partition position detector A is positioned in front of the velvet cutting blade 4, and the distance between the first latitudinal partition position detector A and the velvet cutting blade 4 is an advance E; when the moving platform 1 moves from the right side to the left side of the loom, which is generally called a return stroke, the second latitudinal partition position detector B is in front of the cut pile blade 4, and the distance between the second latitudinal partition position detector B and the cut pile blade 4 is an advance E; in such a two-way moving system, it is necessary to provide two detectors, otherwise the advance E cannot be guaranteed, and the two detectors are located symmetrically with respect to the center of the blade, so as to guarantee the same E value for the forward and return paths, and to guarantee the same phase of the signals of the two detectors. E =1 indicates that the distance is 1d, E =2 indicates that the distance is 2d, E =3 indicates that the distance is 3D, and the blade position data is read based on the fact that the E value is subtracted after the controller counts the detector positions to determine the blade position.

When the moving platform 1 moves from left to right, namely a forward stroke, the controller counts the number of edges of the square wave signal sent by the first zonal position detector a, so that the current position can be known. Since the first zonal position detector a is located at a distance difference E from the pile cutting blade 4, it will be read after subtracting the value of E from the position count. The data sequence of the data rows in the pattern plate reading program read by the controller is as follows: b (1), B (2), \8230;, B (N-1), B (N), are positive sequence data. The controller processes the signals from detector a and detector B in an or-like manner, such that when detector a moves out of the fabric width, i.e., outside the marker zone, detector B remains in the marker zone, and the controller continues to count in an or-like manner. When the moving platform 1 moves from right to left, namely, returns, the controller counts the number of edges of the square wave signal sent by the second latitudinal partition position detector B, and then the current position of the return can be known. Since the second zonal position detector B is at a distance difference E from the pile cutting blade 4, it will be read after subtracting the value of E from the position count. The data sequence of the controller reading the data rows in the pattern plate program is as follows: b (N), B (N-1), B (N-2), \8230;, B (2), B (1), are reverse order data. When detector B moves out of the fabric width, i.e. outside the marker zone, detector a remains in the marker zone and the controller continues counting in the two or' manner.

It should be noted that "black and white" is used herein as a generic term, and means that "black and white" can be replaced by other colors or modes (rough/smooth) for reflection (white) or non-reflection (black) of the light source signal.

As shown in FIG. 7, the fabric 17 is cut and divided to include an upper fabric base 1701, an upper fabric low pile 1703, an upper fabric high pile 1705, an upper fabric 1/2 pile high 1707, a lower fabric high pile 1706, a lower fabric low pile 1704, a lower fabric base 1702 and a lower fabric 1/2 pile high 1708. The effect of the high pile portion can be seen more clearly by adding 1/2 of the pile height compared to the pattern of figure 6.

When the single-blade velvet is cut, the upper fabric and the lower fabric are necessarily in complementary patterns, namely, a high position corresponds to a low position, and a low position corresponds to a high position. If the double-blade cut velvet is used, patterns which are not complementary up and down can be manufactured, and even patterns which are independent of each other can be manufactured.

Example 6:

as shown in fig. 11, the pattern program consists of a data part and a file part; the data part comprises a data row consisting of a plurality of bytes in the X direction, the data row is sequentially arranged in the Y direction to form a two-dimensional byte matrix, and the byte matrix is the pattern data of the cut pile pattern; the X direction is a weft yarn direction from left to right, the width of the fabric in the X direction is M, the number of bytes of each data row is N, and the partition width D = M/N of each byte corresponding to the X direction; the numerical value of each byte corresponds to the velvet height at the current position, namely the height position of the velvet cutting blade, and each data line corresponds to a velvet height cutting curve on the velvet surface; each data line counted by the number of wefts is progressively increased in the Y direction according to the weft density interval, and the whole relief product formed by the pile height fluctuation is obtained; the file section includes the following information: file name, establishing time, author, total byte number W of the file, total weft number S, byte number N of data row, pile height coefficient K and single knife or double knives; the file part occupies a fixed byte number T at the front part of the tattooing program, and the data part is started from T +1 bytes and satisfies the following conditions: w = T + S × N.

In the figure, the thick black frame is the pattern data, and from left to right, the data are: first data line: b (1), B (2), B (3), \8230;, B (N). From bottom to top, the number of picks is incremented, each corresponding to a data row.

For example, the fabric width M =1600mm, and the defined data width D =10mm, the number of bytes N = M/D =1600/10=160 per data row, which indicates that the cutting curve is represented by 160 bytes of data in each raised pile. The value of each byte, representing the pile height at the current location, defines 80H as 1/2 pile height, the cut midline of the double layer fabric.

A pile height coefficient K is defined, which is the conversion coefficient between the binary number in the plate data and the actual pile height in millimeters, e.g. K =0.2, i.e. 5k =1mm.

If the double-blade velvet cutting process is adopted, each position corresponds to2 bytes of data, and the number of bytes of each data line is doubled to be 2N. The arrangement sequence of the appointed double-blade data is as follows: the front cutter data is in front, and the back cutter data is in back. Referring to fig. 3, in the forward stroke, the second cutting blade 4' is a front blade, and the cutting blade 4 is a rear blade; in the return stroke, the pile cutting blade 4 is a front knife and the second pile cutting blade 4' is a rear knife. The arrangement positions of the front and rear blades have a distance, and the value of the division value is F.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments, or make equivalent substitutions and improvements to part of the technical features of the foregoing embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
