Description

Technical Field

[0001] This utility model relates to the field of textile printing technology, and more specifically, to a high-efficiency printing device. Background Technology

[0002] A textile printing device is a specialized piece of equipment used to print patterns, colors, or text on fabrics. For mass production, roller-type printing devices are typically used, such as a textile printing machine disclosed in the prior art. This machine includes a base plate with four support rods fixedly connected to its bottom. Two first fixed plates are fixedly connected to the top of the base plate. A first roller is mounted on the outer wall of each first fixed plate. A recycling bin is fixedly connected to the bottom of the base plate, with a drain outlet at its bottom. A second fixed plate is fixedly connected to the top of the base plate, with two limit grooves. An adjustment mechanism, comprising a limit plate and a tension spring, is connected through the limit grooves. Two limit plates are also present.

[0003] However, the aforementioned existing technology can only print on one piece of greige fabric, resulting in low production efficiency of finished fabric. Summary of the Invention

[0004] To address the problem that existing technologies can only print on one piece of fabric, resulting in low production efficiency of finished fabrics, this invention provides a high-efficiency printing device that can improve the production efficiency of finished fabrics.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] A high-efficiency printing apparatus includes a frame and a first feed roller, a first guide roller, a printing roller, a second guide roller, and a first take-up roller, all rotatably connected to the frame and arranged sequentially. It also includes a second feed roller, a third guide roller, a fourth guide roller, and a second take-up roller, all rotatably connected to the frame and arranged sequentially. The second feed roller is located below the first take-up roller; the third guide roller is located below the second guide roller; the fourth guide roller is located below the first guide roller; and the second take-up roller is located below the first feed roller. The line connecting the bottom end of the first guide roller and the bottom end of the second guide roller is parallel to the line connecting the top end of the third guide roller and the top end of the fourth guide roller.

[0007] Understandably, the first feed roller is used to wind up the unprinted fabric roll (or semi-finished fabric roll) on the upper layer, continuously releasing the fabric according to production needs, providing a material base for the subsequent printing station; the first guide roller and the second guide roller are used to adjust the fabric travel path and eliminate uneven tension and wrinkles during the fabric release stage; the printing roller is used to transfer the pattern to the fabric; the first take-up roller is used to neatly and stably wind the printed fabric into a roll.

[0008] In the above technical solution, the upper layer of fabric roll is fed out from the bottom end of the first feed roller, then passes sequentially through the bottom end of the first guide roller, the top end of the printing roller, and the bottom end of the second guide roller, finally winding around the first take-up roller from the bottom end. The working process and principle of the second feed roller, the third guide roller, the fourth guide roller, and the second take-up roller are the same as those of the first take-up roller, the first guide roller, the second guide roller, and the first take-up roller, respectively, but the forward direction of the lower layer fabric is opposite to that of the upper layer fabric. With the above arrangement, the upper and lower layers of fabric can contact the printing roller simultaneously, and the two fabrics can be printed and dyed at the same time when the printing roller rotates, which can improve the production efficiency of the finished fabric.

[0009] Preferably, the system further includes a first heating roller and a second heating roller, both rotatably connected to the frame. The first heating roller is located between the first feed roller and the first guide roller, with its top end higher than the bottom end of the first feed roller and the bottom end of the first guide roller, and its bottom end lower than the top end of the fourth guide roller and the top end of the second take-up roller. The second heating roller is located between the second guide roller and the first take-up roller, with its top end higher than the bottom end of the second guide roller and the bottom end of the first take-up roller, and its bottom end lower than the top end of the second feed roller and the top end of the third guide roller. The first heating roller can preheat the upper fabric layer, which not only dries the surface moisture of the fabric and prevents ink diffusion but also improves the fabric's adsorption of ink, thus optimizing the printing effect of the upper fabric layer. The first heating roller can also heat the lower finished fabric layer, thereby fixing the printed pattern. Different heating and finishing effects can be achieved by changing the speed difference between the first heating roller and the fabric movement. The function of the second heating roller is similar to that of the first heating roller, and therefore will not be described in detail.

[0010] Preferably, the system further includes a first linkage component, a second linkage component, a third linkage component, and a fourth linkage component; the first feed roller and the first take-up roller are drivenly connected via the first linkage component; the first guide roller and the second guide roller are drivenly connected via the second linkage component; the second feed roller and the second take-up roller are drivenly connected via the third linkage component; and the third guide roller and the fourth guide roller are drivenly connected via the fourth linkage component. The first linkage component enables the first feed roller and the first take-up roller to rotate synchronously, thereby ensuring that the feed rate and take-up rate are the same, avoiding the impact of accumulated wrinkles or excessive stretching on the printing quality. The second linkage component enables the first guide roller and the second guide roller to rotate synchronously, ensuring uniform fabric tension on both sides of the printing roller, making the fabric surface smoother, thereby improving the printing quality. The functions and effects of the second linkage component and the fourth linkage component are the same as those of the first linkage component and the third linkage component, respectively, and therefore will not be described in detail.

[0011] The aforementioned linkage components can be driven by synchronous belts, gears, chains, etc.

[0012] Preferably, the first linkage component includes a first synchronous belt, and the first feed roller and the first take-up roller are connected by the first synchronous belt; the second linkage component includes a second synchronous belt, and the first guide roller and the second guide roller are connected by the second synchronous belt; the third linkage component includes a third synchronous belt, and the second feed roller and the second take-up roller are connected by the third synchronous belt; the fourth linkage component includes a fourth synchronous belt, and the third guide roller and the fourth guide roller are connected by the fourth synchronous belt.

[0013] Preferably, the device further includes a first motor, a second motor, a third motor, a fourth motor, a fifth motor, a sixth motor, and a seventh motor mounted on the frame; the power output end of the first motor is connected to the first feed roller or the first take-up roller, thereby driving the first feed roller and the first take-up roller to rotate synchronously; the power output end of the second motor is connected to the first guide roller or the second guide roller, thereby driving the first guide roller and the second guide roller to rotate synchronously; the power output end of the third motor is connected to the second feed roller or the second take-up roller, thereby driving the second feed roller and the second take-up roller to rotate synchronously; the power output end of the fourth motor is connected to the third guide roller or the fourth guide roller, thereby driving the third guide roller and the fourth guide roller to rotate synchronously; the power output end of the fifth motor is connected to the printing roller, thereby driving the printing roller to rotate; the power output end of the sixth motor is connected to the first heating roller, thereby driving the first heating roller to rotate; and the power output end of the seventh motor is connected to the second heating roller, thereby driving the second heating roller to rotate.

[0014] Preferably, the frame is provided with a first lifting drive mechanism and a second lifting drive mechanism. The power output end of the first lifting drive mechanism is connected to a first slider, which is slidably connected to the frame in the vertical direction. The first guide roller and the second guide roller are both rotatably connected to the first slider. The power output end of the second lifting drive mechanism is connected to a second slider, which is slidably connected to the frame in the vertical direction. The third guide roller and the fourth guide roller are both rotatably connected to the second slider. The first lifting drive mechanism drives the first slider to rise and fall, thereby causing the first guide roller and the second guide roller to rise and fall synchronously. The second lifting drive mechanism drives the second slider to rise and fall, thereby causing the second guide roller and the third guide roller to rise and fall synchronously. The first and second lifting drive mechanisms allow for adjustment of the distance between the upper and lower guide rollers. When processing fabrics of different thicknesses, the distance between the upper and lower guide rollers can be adjusted according to the actual situation to ensure that both fabrics can make good contact with the printing roller, achieving high-quality printing and adapting to different production needs.

[0015] The first lifting drive mechanism may be a motor lead screw drive mechanism, an electric push rod drive mechanism, a gear and rack drive mechanism, a synchronous belt drive mechanism, a cylinder drive mechanism, etc.

[0016] Preferably, there are two first lifting drive mechanisms, each including an eighth motor mounted on the frame and a first lead screw rotatably connected to the frame. The power output end of the eighth motor is connected to one end of the first lead screw, and the first slider is threadedly connected to the first lead screw. One end of the first guide roller and one end of the second guide roller are each rotatably connected to one of the first sliders, and the other ends of the first guide roller and the second guide roller are each rotatably connected to the other first slider. There are also two second lifting drive mechanisms, each including a ninth motor mounted on the frame and a second lead screw rotatably connected to the frame. The power output end of the eighth motor is connected to one end of the second lead screw, and the second slider is threadedly connected to the second lead screw. One end of the third guide roller and one end of the fourth guide roller are each rotatably connected to one of the second sliders, and the other ends of the third guide roller and the fourth guide roller are each rotatably connected to the other first slider. The eighth motor drives the first lead screw to rotate, and the rotational motion of the first lead screw is converted into the lifting motion of the first slider, thereby driving the first and second guide rods to rise and fall. The working process and principle of the second lifting drive mechanism are the same as those of the first lifting drive mechanism, so they will not be described again. The motor screw drive mechanism can precisely adjust the lifting distance of the guide roller. Moreover, the motor screw mechanism has higher reliability. In the event of an unexpected power failure, the first slider and the second slider can still be locked on the first screw and the second screw respectively, preventing accidental slippage.

[0017] Preferably, the system further includes a distance sensor for measuring the vertical distance between the first slider and the second slider. The distance between the upper and lower guide rollers can be determined based on the vertical distance between the first and second sliders. If the measured distance differs from the target distance, the distance between the upper and lower guide rollers is further adjusted using the first and second lifting drive mechanisms to ensure that the upper and lower guide rollers are in appropriate positions, thereby ensuring printing quality.

[0018] Preferably, the ranging sensor can be one of a laser ranging sensor, an infrared ranging sensor, or an ultrasonic ranging sensor.

[0019] Preferably, the ranging sensor is a laser ranging sensor, which includes a transmitting module and a receiving module. The transmitting module is mounted on the first slider, and the receiving module is mounted on the second slider. The structure and principle of the laser ranging sensor are existing technologies and will not be described in detail here. Compared with other sensors, the laser ranging sensor has higher ranging accuracy and smaller size.

[0020] Preferably, the outer surfaces of the first, second, third, and fourth guide rollers are all coated with a nano-coating. The nano-coating increases the friction and wear resistance of the guide roller surface, allowing the guide rollers to better guide the fabric under different spacing adjustments, preventing slippage during the printing process. Furthermore, the nano-coating has a self-cleaning function, reducing the adhesion of impurities from the fabric to the guide roller surface and improving printing quality.

[0021] The beneficial effects of this utility model are:

[0022] 1. Below the first feed roller, first guide roller, second guide roller, and first take-up roller, a second take-up roller, a fourth guide roller, a third guide roller, and a first feed roller are respectively arranged. The first feed roller, first guide roller, second guide roller, and first take-up roller are responsible for conveying the upper layer of fabric, while the second feed roller, third guide roller, fourth guide roller, and second take-up roller are responsible for conveying the lower layer of fabric. The printing roller contacts both the upper and lower layers of fabric simultaneously, thereby transferring the pattern to both layers. This printing machine can print on two fabrics simultaneously, improving the production efficiency of finished fabrics.

[0023] 2. The first feed roller and the first take-up roller are connected by a first synchronous belt drive, and the second feed roller and the second take-up roller are connected by a third synchronous belt drive, which can make the feed rate and take-up rate the same, avoiding fabric accumulation, wrinkles or excessive stretching; the first guide roller and the second guide roller are connected by a second synchronous belt drive, and the third guide roller and the fourth guide roller are connected by a fourth synchronous belt drive, which can ensure that the fabric tension on both sides of the printing roller is uniform, making the fabric surface smoother, thereby improving the printing quality.

[0024] 3. The spacing between the upper and lower guide rollers is adjustable, which ensures that both pieces of fabric can make good contact with the printing roller, achieving high-quality printing and thus adapting to different production needs.

[0025] 4. Set a distance sensor to measure the distance between the upper and lower guide rollers in order to accurately adjust the distance between the upper and lower guide rollers and ensure printing quality. Attached Figure Description

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0032] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0033] Example 1

[0034] This embodiment is a first embodiment of a high-efficiency printing device. (See attached document.) Figure 1 The device includes a frame 1 (not shown in the figure) and a first feed roller 2, a first guide roller 3, a printing roller 4, a second guide roller 5, and a first take-up roller 6, all rotatably connected to the frame 1 and arranged sequentially. The device also includes a second feed roller 7, a third guide roller 8, a fourth guide roller 9, and a second take-up roller 10, all rotatably connected to the frame 1 and arranged sequentially. The second feed roller 7 is located below the first take-up roller 6; the third guide roller 8 is located below the second guide roller 5; the fourth guide roller 9 is located below the first guide roller 3; and the second take-up roller 10 is located below the first feed roller 2. The line connecting the bottom end of the first guide roller 3 and the bottom end of the second guide roller 5 is parallel to the line connecting the top end of the third guide roller 8 and the top end of the fourth guide roller 9.

[0035] Understandably, the first feed roller 2 is used to wind the unprinted fabric roll or semi-finished fabric roll and continuously release the fabric according to production needs; the first guide roller 3 and the second guide roller 5 are used to adjust the travel path of the fabric 18 and eliminate uneven tension and wrinkles during the fabric release stage; the printing roller 4 is used to transfer the pattern to the fabric; and the first take-up roller 6 is used to neatly and stably wind the finished printed fabric into a roll.

[0036] The working principle or workflow of this embodiment is as follows: During implementation, the upper layer of fabric roll is fed out from the bottom end of the first feed roller 2, then sequentially passes through the bottom end of the first guide roller 3, the top end of the printing roller 4, and the bottom end of the second guide roller 5, finally winding around the first take-up roller 6 from its bottom end. The working process and principle of the second feed roller, the third guide roller 8, the fourth guide roller 9, and the second take-up roller 10 are the same as those of the first take-up roller 6, the first guide roller 3, the second guide roller 5, and the first take-up roller 6, respectively, but the forward direction of the lower layer fabric 18 is opposite to that of the upper layer fabric 18. Through this arrangement, the upper layer fabric 18 and the lower layer fabric 18 can simultaneously contact the printing roller 4. When the printing roller 4 rotates, both fabrics 18 can be printed simultaneously, thus improving the production efficiency of the finished fabric.

[0037] Example 2

[0038] This embodiment is a second embodiment of a high-efficiency printing device. This embodiment is similar to Embodiment 1, except that, as described above... Figure 1 and Figure 2The system also includes a first heating roller 11 and a second heating roller 12, both rotatably connected to the frame 1. The first heating roller 11 is located between the first feed roller 2 and the first guide roller 3. The top of the first heating roller 11 is higher than the bottom of the first feed roller 2 and the bottom of the first guide roller 3, and the bottom of the first heating roller 11 is lower than the top of the fourth guide roller 9 and the top of the second take-up roller 10. The second heating roller 12 is located between the second guide roller 5 and the first take-up roller 6. The top of the second heating roller 12 is higher than the bottom of the second guide roller 5 and the bottom of the first take-up roller 6, and the bottom of the second heating roller 12 is lower than the top of the second feed roller 7 and the top of the third guide roller 8. The first heating roller 11 can preheat the upper fabric, which not only dries the surface moisture of the fabric 18 and prevents ink diffusion, but also improves the fabric 18's adsorption of ink, thus optimizing the printing effect of the upper fabric 18. The first heating roller 11 can also heat the lower finished fabric to fix the printed pattern. Different heating and finishing effects can be achieved by changing the speed difference between the first heating roller 11 and the fabric 18. The function of the second heating roller 12 is similar to that of the first heating roller 11, so it will not be described in detail.

[0039] Furthermore, it also includes a first linkage assembly, a second linkage assembly, a third linkage assembly, and a fourth linkage assembly; the first feed roller 2 and the first take-up roller 6 are connected by a transmission via the first linkage assembly; the first guide roller 3 and the second guide roller 5 are connected by a transmission via the second linkage assembly; the second feed roller 7 and the second take-up roller 10 are connected by a transmission via the third linkage assembly; and the third guide roller 8 and the fourth guide roller 9 are connected by a transmission via the fourth linkage assembly. The first linkage assembly enables the first feed roller and the first take-up roller 6 to rotate synchronously, thereby ensuring that the feed rate and take-up rate are the same, avoiding the impact of accumulated wrinkles or excessive stretching on the printing quality. The second linkage assembly enables the first guide roller 3 and the second guide roller 5 to rotate synchronously, ensuring uniform tension of the fabric 18 on both sides of the printing roller 4, making the fabric surface smoother, thereby improving the printing quality. The functions and effects of the second and fourth linkage assemblies are the same as those of the first and third linkage assemblies, respectively, and therefore will not be described in detail.

[0040] Specifically, the first linkage assembly includes a first synchronous belt 13, through which the first feed roller 2 and the first take-up roller 6 are connected; the second linkage assembly includes a second synchronous belt 14, through which the first guide roller 3 and the second guide roller 5 are connected; the third linkage assembly includes a third synchronous belt, through which the second feed roller 7 and the second take-up roller 10 are connected; and the fourth linkage assembly includes a fourth synchronous belt, through which the third guide roller 8 and the fourth guide roller 9 are connected. The specific configuration of the third and fourth synchronous belts can be referenced to the first synchronous belt 13 and the second synchronous belt 14.

[0041] Furthermore, it also includes a first motor 15, a second motor 16, a third motor, a fourth motor, a fifth motor, a sixth motor, and a seventh motor mounted on the frame 1; the power output end of the first motor 15 is connected to the first feed roller 2 or the first take-up roller 6, thereby driving the first feed roller 2 and the first take-up roller 6 to rotate synchronously; the power output end of the second motor 16 is connected to the first guide roller 3 or the second guide roller 5, thereby driving the first guide roller 3 and the second guide roller 5 to rotate synchronously; the power output end of the third motor is connected to the second feed roller 7 or the second take-up roller 6. The fabric roller 10 is connected, thereby driving the second fabric feeding roller 7 and the second fabric receiving roller 10 to rotate synchronously; the power output end of the fourth motor is connected to the third fabric guide roller 8 or the fourth fabric guide roller 9, thereby driving the third fabric guide roller 8 and the fourth fabric guide roller 9 to rotate synchronously; the power output end of the fifth motor is connected to the printing roller 4, thereby driving the printing roller 4 to rotate; the power output end of the sixth motor is connected to the first heating roller 11, thereby driving the first heating roller 11 to rotate; the power output end of the seventh motor is connected to the second heating roller 12, thereby driving the second heating roller 12 to rotate.

[0042] Other features, working principles, and beneficial effects of this embodiment are the same as those of Embodiment 1.

[0043] Example 3

[0044] This embodiment is a third embodiment of a high-efficiency printing device. This embodiment is similar to embodiment 2, except that, as described in the following... Figures 1 to 3 The frame 1 is equipped with a first lifting drive mechanism 17 and a second lifting drive mechanism with the same structure as the first lifting drive mechanism 17. The power output end of the first lifting drive mechanism 17 is connected to a first slider 1703, which is slidably connected to the frame 1 in the vertical direction. The first guide roller 3 and the second guide roller 5 are both rotatably connected to the first slider 1703. The power output end of the second lifting drive mechanism is connected to a second slider, which is slidably connected to the frame 1 in the vertical direction. The third guide roller 8 and the fourth guide roller 9 are both rotatably connected to the second slider. The first lifting drive mechanism 17 drives the first slider 1703 to rise and fall, thereby causing the first guide roller 3 and the second guide roller 5 to rise and fall synchronously. The second lifting drive mechanism drives the second slider to rise and fall, thereby causing the second guide roller 5 and the third guide roller 8 to rise and fall synchronously. The first lifting drive mechanism 17 and the second lifting drive mechanism can adjust the distance between the upper and lower guide rollers. When it is necessary to process fabrics 18 of different thicknesses, the distance between the upper and lower guide rollers can be adjusted according to the actual situation to ensure that both fabrics 18 can make good contact with the printing roller 4, so as to achieve high-quality printing and thus adapt to different production needs.

[0045] Furthermore, there are two first lifting drive mechanisms 17, each including an eighth motor 1701 mounted on the frame 1 and a first lead screw 1702 rotatably connected to the frame 1. The power output end of the eighth motor 1701 is connected to one end of the first lead screw 1702, and the first slider 1703 is threadedly connected to the first lead screw 1702. One end of the first guide roller 3 and one end of the second guide roller 5 are rotatably connected to one of the first sliders 1703, and the other end of the first guide roller 3 and the other end of the second guide roller 5 are rotatably connected to the other first slider 1703. There are two second lifting drive mechanisms, each including a ninth motor mounted on the frame 1 and a second lead screw rotatably connected to the frame 1. The power output end of the eighth motor 1701 is connected to one end of the second lead screw, and the second slider is threadedly connected to the second lead screw. One end of the third guide roller 8 and one end of the fourth guide roller 9 are rotatably connected to one of the second sliders, and the other end of the third guide roller 8 and the other end of the fourth guide roller 9 are rotatably connected to the other first slider. The eighth motor 1701 drives the first lead screw 1702 to rotate. The rotational motion of the first lead screw 1702 is converted into the lifting motion of the first slider 1703, thereby driving the first guide roller 3 and the second guide roller 5 to rise and fall. The working process and principle of the second lifting drive mechanism are the same as those of the first lifting drive mechanism 17, and therefore will not be described again. The motor lead screw drive mechanism can finely adjust the lifting distance of the guide rollers. Moreover, the motor lead screw mechanism has higher reliability. In the event of an unexpected power failure, the first slider 1703 and the second slider can still be locked onto the first lead screw 1702 and the second lead screw respectively, preventing accidental slippage.

[0046] Furthermore, it also includes a distance sensor 19, which is used to measure the vertical distance between the first slider 1703 and the second slider. The distance between the upper and lower guide rollers can be determined based on the vertical distance between the first slider 1703 and the second slider. If there is a difference between the measured distance and the target distance, the first lifting drive mechanism 17 and the second lifting drive mechanism are used to continue to adjust to ensure that the upper and lower guide rollers are in the appropriate positions and to ensure the printing quality.

[0047] Specifically, the ranging sensor 19 is a laser ranging sensor, which includes a transmitting module and a receiving module. The transmitting module is mounted on the first slider 1703. Figure 3 Mark 19 indicates the transmitting module; the receiving module is mounted on the second slider. The mounting position of the receiving module is not shown in the figure, but it can be determined from the mounting position of the transmitting module. The structure and principle of the laser rangefinder are existing technologies and will not be described in detail here. Compared to other sensors, the laser rangefinder has higher ranging accuracy and a smaller size.

[0048] Furthermore, the outer surfaces of the first guide roller 3, the second guide roller 5, the third guide roller 8, and the fourth guide roller 9 are all coated with a nano-coating. This nano-coating increases the friction and wear resistance of the guide roller surfaces, allowing the guide rollers to better guide the fabric 18 under different spacing adjustments, preventing slippage of the fabric 18 during the printing process. Moreover, the nano-coating has a self-cleaning function, reducing the adhesion of impurities from the fabric 18 to the guide roller surfaces and improving printing quality.

[0049] Other features, working principles, and beneficial effects of this embodiment are the same as those of Embodiment 2.

[0050] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0051] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description, and it is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
