Description

Technical Field

[0001] The invention belongs to the field of fabric printing, and in particular relates to a fabric printing flower height control system. Background Art

[0002] Fabric printing is an important method of textile processing. Through the process of forming patterns on fabrics through printing methods, a variety of printing methods can be achieved, such as direct pigment printing, silk printing, knitted underwear printing, etc. These printing methods not only enrich the visual effects of the fabric, but also provide consumers with a variety of choices;

[0003] The printed pattern is repeated on the fabric surface to ensure the continuity of fabric quality. The control of pattern height (circumference) is a key factor in ensuring pattern shape retention and reproducibility. Due to the physical limitations of traditional flat screen or rotary screen printing, the pattern height circumference of each pattern is usually 640mm, 920mm, and 1080mm. The control method generally adopted is to manually measure the pattern height data during the subsequent finishing process and compare it with the pattern height data printed on the fabric edge. The data is fed back to the operator of the finalizing machine, who then overfeeds the data to achieve pattern height control.

[0004] However, existing technologies have the following shortcomings: Traditional control methods suffer from time lag, low control accuracy, and high labor intensity. Especially with the recent popularity of digital printing technology, more and more digital printing patterns, such as gradient patterns, rendered patterns, non-geometric patterns, and long patterns, are difficult to measure and control manually, increasing measurement time and difficulty and reducing work efficiency. In some extreme cases, the perimeter of the high-quality printing needs to reach over 1500mm or even close to 2000mm to meet different styles, making manual measurement impossible.

[0005] This application proposes a fabric printing height control system to improve the above-mentioned defects. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a fabric printing flower height control system capable of accurately measuring the height circumference of a completed printed flower.

[0009] In a specific feasible implementation scheme, the interior of the printing device includes a pattern height control system and an industrial detection camera. The pattern height control system adopts digital image processing, pattern recognition and information fusion technology, and uses the industrial detection camera as a detection element to detect in real time the pre-printed triangular pattern height cycle marks on the edge of the running textile fabric, and obtain the pattern height cycle period. According to the running speed of the main chain of the setting machine inside the printing device and the real-time speed of the cloth guide roller, the speed of the overfeed roller of the setting machine is preset and adjusted in real time through logical calculation to ensure that the pattern height of the fabric is as set after entering the main chain.

[0010] In a specific possible implementation scheme, the body includes a support plate, a limit plate and a clearance groove. Support plates are symmetrically installed on both sides of the interior of the body, and a limit plate is installed on one side of the support plate, and a clearance groove is provided on the limit plate.

A pressure plate is installed at the bottom of the connecting plate. Both ends of the connecting plate are connected to the lifting block. Ball screws are threaded on the two lifting blocks. The top of the ball screw is connected to the handle, and the inside of the ball screw has a self-locking structure.

[0012] In a specific embodiment, the bottom of the pressing plate contacts the textile fabric and has an arc-shaped structure.

[0013] In a specific possible implementation scheme, a drying device and a shaking mechanism are further installed at the bottom of the machine body, and both sides of the drying device and the shaking mechanism are connected to the control box.

[0014] In a specific feasible implementation scheme, the drying device includes a bottom box, a top cover, an air guide groove and a swinging device. The top of the bottom box is movably engaged with the top cover, the top cover is densely covered with air guide grooves, and the air guide grooves are arranged in an alternating array. One side of the bottom box is rotatably engaged with a swinging device.

[0015] In a specific possible implementation scheme, a heating tube and a fan are installed inside the bottom box. The heating tube can generate heat when in operation, and a plurality of fans are arranged in an equidistant array.

[0016] In a specific feasible implementation scheme, the swing device includes a turntable, an eccentric column, a swing block, meshing teeth and a gear ring. The turntable rotates and controls the drive with the side wall of the control box. An eccentric column is fixed on the turntable. A swing block is slidably fitted on the eccentric column. A positioning column is provided on the swing block for positioning. A plurality of meshing teeth are provided on the top of the swing block. The plurality of meshing teeth mesh with the gear ring gears to drive the gear ring to rotate. The gear ring is located on one side of the bottom box and is fixed thereto.

[0017] In a specific feasible implementation scheme, the shaking mechanism includes a bearing seat, a main shaft, a fixed plate and a protruding tube. The bearing seats are symmetrically arranged in two groups, and the two groups of bearing seats are connected by the main shaft and the fixed plate. The protruding tubes are symmetrically installed on the fixed plate.

[0018] In a specific possible implementation scheme, the fixing plate is symmetrically provided with snap-fitting grooves, which are movably engaged with the protruding tubes.

[0019] According to the technical solution proposed above, the fabric printing height control system of the present invention has the following beneficial effects:

[0020] (1) The present invention provides a pattern height control system and an industrial detection camera in the printing device. With the help of digital image processing, pattern recognition and information fusion technology in the pattern height control system, the industrial detection camera is used as a detection element to detect the pre-printed triangular pattern height cycle mark on the running textile fabric in real time and obtain the pattern height cycle period. In addition, the speed of the main chain of the setting machine in the printing device, the real-time speed of the cloth guide roller, and the speed of the overfeed roller in the setting machine can be preset and adjusted in real time through logical calculation to ensure that the pattern height of the fabric is the set value after entering the main chain.

[0021] (2) The present invention adds a flattening mechanism to the printing device body, and the arc-shaped structure at the bottom of the pressing plate contacts the textile fabric. With the help of the conveying movement of the fabric, the fabric can be flattened and adjusted to prevent wrinkles on the fabric, thereby improving the yield and effect of printing.

[0022] (3) The present invention adds a support plate to the printing device body, and the fabric is transported on the support plate. With the help of the clearance groove on one side of the limit plate, one side of the textile fabric can enter the clearance groove during transportation, thereby positioning one side of the fabric and preventing the fabric from shifting during transportation.

[0023] (4) The present invention adds a shaking mechanism to the printing device body, drives the main shaft and the fixed plate to rotate through the control box, and uses the raised tubes located at both ends of the fixed plate to alternately contact the bottom of the fabric during rotation, thereby producing a slight impact on the fabric, thereby causing the fabric surface to shake, and can shake off the dust adhering to the fabric surface, avoiding the dust adhesion and affecting the printing effect of the fabric. By pushing the raised tube, the installation position of the raised tube on the clamping groove can be adjusted, thereby adjusting the distance between the raised tube and the fabric and the vibration amplitude, so that the shaking mechanism can be applied to different types of textile fabrics.

[0024] (5) The present invention adds a drying device to the printing device body, drives the turntable to rotate and drives the eccentric column to rotate together, and with the help of the limited sliding between the swing block and the eccentric column, the swing block will swing left and right when the turntable rotates, and the gear ring will rotate half a circle through gear engagement, and drive the bottom box connected to it to swing together, and with the help of several fans in the bottom box, upward wind is generated. After passing through the heating tube, the wind will become hot air to dry the printed fabric, so as to avoid the printing being incomplete due to the printing not being completely dry right after processing, which affects the quality.

DETAILED DESCRIPTION

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0039] Example 1: Please refer to Figures 1-6 , the specific embodiments of the present invention are as follows:

[0040] A fabric printing flower height control system comprises a machine body 1, a control box 2, a printing device 3 and a flattening mechanism 4. The machine body 1 is provided with a printing device 3 capable of printing textile fabrics. The machine body 1 is provided with a control box 2 on both sides of the machine body 1. The control box 2 has a built-in power supply motor capable of driving the machine body 1 and the printing device 3 to operate. One side of the printing device 3 is provided with a flattening mechanism 4 connected to the machine body 1. The flattening mechanism 4 can flatten and wrinkle-proof the conveyed textile fabric.

[0041] See also Figure 2-Figure 4 The interior of the printing device 3 includes a pattern height control system and an industrial detection camera. The pattern height control system adopts digital image processing, pattern recognition and information fusion technology, and uses the industrial detection camera as a detection element to detect in real time the pre-printed triangular pattern height cycle mark of the cloth edge on the running textile fabric, and obtain the pattern height cycle period. According to the running speed of the main chain of the setting machine inside the printing device 3 and the real-time speed of the cloth guide roller, the speed of the overfeed roller in the setting machine is preset and adjusted in real time through logical calculation to ensure that the pattern height of the fabric is as set after entering the main chain.

[0042] See also Figure 2-Figure 5The machine body 1 includes a support plate 11, a limiting plate 12 and a giveway groove 13. Support plates 11 are symmetrically installed on both sides of the interior of the machine body 1. The support plates 11 can support the transportation of the fabric. A limiting plate 12 is installed on one side of the support plate 11. The limiting plate 12 is provided with a giveway groove 13. Through the setting of the giveway groove 13 on the limiting plate 12, one side of the textile fabric can enter the giveway groove 13 during transportation and move in the giveway groove 13. With the help of the giveway groove 13 and the limiting plate 12, one side of the fabric is positioned, which can prevent the fabric from shifting during transportation, thereby affecting the printing effect.

[0043] See also Figure 6 The flattening mechanism 4 includes a connecting plate 41, a pressing plate 42, a lifting block 43, a mounting plate 44, a handle 45 and a ball screw 46. The bottom of the connecting plate 41 is installed with a pressing plate 42. Both ends of the connecting plate 41 are connected to the lifting block 43. The two lifting blocks 43 are threaded with ball screws 46. The top of the ball screw 46 is connected to the handle 45, and the inside of the ball screw 46 has a self-locking structure.

[0044] See also Figure 6 The bottom of the pressing plate 42 is in contact with the textile fabric and has an arc-shaped structure. When the pressing plate 42 is in contact with the textile fabric, it can flatten and adjust the fabric with the help of the conveying movement of the fabric to prevent wrinkles on the fabric, and the arc-shaped shape can prevent the pressing plate 42 from causing damage to the fabric.

[0045] Example 2: Please refer to Figure 7-11 , the specific embodiments of the present invention are as follows:

[0046] See also Figure 7 A drying device 5 and a shaking mechanism 6 are also installed at the bottom of the body 1. Both sides of the drying device 5 and the shaking mechanism 6 are connected to the control box 2 and can be driven by the control box 2.

[0047] See also Figure 8-Figure 9 The drying device 5 includes a bottom box 51, a top cover 52, an air guide groove 53 and a swinging device 54. The top of the bottom box 51 is movably engaged with the top cover 52. The top cover 52 is densely covered with air guide grooves 53, and the air guide grooves 53 are arranged in an alternating array. One side of the bottom box 51 is rotated and equipped with a swinging device 54, which can drive the bottom box 51 to swing with the help of the swinging device 54. The swinging device 54 is connected to the side wall of the control box 2.

[0048] See also Figure 8-Figure 9A heating tube 511 and a fan 512 are installed inside the bottom box 51. The heating tube 511 can generate heat when running. There are several fans 512 arranged in an equidistant array. The several fans 512 are driven by the control box 2 to generate upward wind force, and the wind force will become hot air after passing through the heating tube 511 to dry the printed fabric.

[0049] See also Figure 9 The eccentric column 542 is fixed on the turntable 541, and the eccentric column 542 is slidably matched with the swing block 543. As the turntable 541 drives the eccentric column 542 to rotate, the swing block 543 is driven to swing left and right by means of the limited sliding between the swing block 543 and the eccentric column 542. A positioning column is provided on the swing block 543 for positioning, and the positioning column is rotated with the positioning column. A plurality of meshing teeth 544 are provided on the top of the swing block 543. The plurality of meshing teeth 544 are engaged with the gear ring 545 to drive the gear ring 545 to rotate. The gear ring 545 is located on one side of the bottom box 51 and is fixed thereto. As the gear ring 545 rotates, the bottom box 51 is driven to swing together.

[0050] See also Figure 10 The shaking mechanism 6 includes a bearing seat 61, a main shaft 62, a fixed plate 63 and a protruding tube 64. The bearing seat 61 is symmetrically provided with two groups. The two groups of bearing seats 61 are connected by the main shaft 62 and the fixed plate 63. The protruding tube 64 is symmetrically installed on the fixed plate 63.

[0051] See also Figure 11 The fixing plate 63 is symmetrically provided with a snap-fitting groove 631, which is movably engaged with the protruding tube 64. The installation position of the protruding tube 64 can be adjusted by means of a number of notches at different distances provided on the snap-fitting groove 631, thereby adjusting the shaking distance and shaking strength of the contact between the protruding tube 64 and the fabric. With the help of the protruding tube 64, the fabric can be shaken during feeding and conveying, thereby shaking off the dust on the surface of the fabric, thereby preventing the dust from affecting the finished printing effect.

[0052] Based on the above embodiment, the specific working principle is as follows:

[0053] The textile fabric is automatically conveyed and fed through the conveying mechanism. At the same time, the main shaft 62 and the fixed plate 63 on the shaking mechanism 6 are driven to rotate through the control box 2. The raised tubes 64 located at both ends of the fixed plate 63 can alternately contact the bottom of the fabric during rotation, thereby producing a slight impact on the fabric, thereby causing the fabric surface to shake, and can shake off the dust adhering to the fabric surface, thereby preventing the dust from adhering and affecting the printing effect of the fabric during printing. By pushing the raised tube 64, the installation position of the raised tube 64 on the clamping groove 631 can be adjusted, thereby adjusting the distance between the raised tube 64 and the fabric and the vibration amplitude;

[0054] Then, as the textile fabric is transported, it will come into contact with the flattening mechanism 4 on the machine body 1. The arc-shaped structure at the bottom of the pressing plate 42 contacts the textile fabric. With the help of the conveying movement of the fabric, the fabric can be flattened and adjusted to prevent wrinkles on the fabric, thereby improving the yield and effect of printing. The fabric will then be transported on the support plate 11 of the machine body 1. With the help of the give-away groove 13 on the limiting plate 12, one side of the textile fabric during transportation can enter the give-away groove 13, and one side of the fabric can be positioned to prevent the fabric from shifting during transportation.

[0055] After the fabric is transported to the printing device 3, the fabric can be printed by the printing device 3, and at the same time, the turntable 541 is driven to rotate. As the turntable 541 rotates, the eccentric column 542 is driven to rotate together, and the limited sliding between the swing block 543 and the eccentric column 542 drives the swing block 543 to swing left and right when the turntable 541 rotates, and drives the gear ring 545 to rotate half a circle through gear meshing. As the gear ring 545 rotates, the bottom box 51 connected to it is driven to swing together, and the multiple fans 512 in the bottom box 51 are driven by the control box 2 to generate upward wind force, and the wind force will become hot air after passing through the heating tube 511, drying the printed fabric, to avoid the printing being incomplete due to the printing being not completely dry right after the processing, thereby affecting the quality.
