Description

Technical Field

[0001] This utility model relates to the field of knitted fabric printing technology, and in particular to a knitted fabric double-sided printing alignment calibration device. Background Technology

[0002] Knitted fabric is a type of fabric made through a knitting process. It is usually formed by one or more yarns interlacing with each other through the knitting action of a knitting machine. Unlike traditional woven fabric (which is made by interlacing warp and weft), knitted fabric uses a loop weaving method, which gives the fabric excellent elasticity and stretch.

[0003] The existing technology has the following problems:

[0004] When knitted fabrics are printed, they are usually aligned and limited by a correction mechanism and then conveyed to the printing mechanism for printing. After printing, they are dried and rolled up. However, the take-up rollers of knitted fabrics are usually firmly fixed to the take-up bracket by fixing bolts. When it is necessary to disassemble and replace the take-up rollers, the mounting plate usually needs to be disassembled with tools due to the bolt fixing method, which makes this process very cumbersome and time-consuming.

A drying mechanism is provided on the top left side of the mounting box. A correction mechanism is installed on the top right side of the base plate. An unwinding mechanism is installed on the top of the base plate and to the right of the correction mechanism.

[0008] The fixing mechanism includes a locking block, a housing, and a fixing rod. The top of the locking block is fixedly connected to the bottom of the movable plate. The right side of the housing is fixedly connected to the left side of the mounting plate. Both ends of the fixing rod are fixedly connected to the inside of the mounting plate. A push rod is slidably connected inside the housing. One end of the push rod is fixedly connected to a fixing seat. Two sliders are slidably connected in the middle of the fixing rod. An L-shaped insert is fixedly connected to the right side of the slider. Springs are sleeved on both ends of the fixing rod. A connecting rod is provided between the slider and the fixing seat.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This utility model provides a double-sided printing alignment calibration device for knitted fabrics. The fixed mechanism can quickly fix and release the movable plate, which is convenient for changing the take-up shaft. When the push rod is pushed, the fixed seat drives the slider to slide on the fixed rod through the connecting rod, so that the L-shaped part is disengaged from the inside of the locking block, and the movable plate can rotate freely. The operation is convenient and the production efficiency is improved.

[0018] 2. This utility model provides a double-sided printing alignment and calibration device for knitted fabrics. The drying mechanism uses a drying fan to blow hot air onto the printed fabric through an air duct for drying. At the same time, a motor drives a half-gear to rotate. The half-gear meshes with a gear frame, causing the gear frame to drive a brush plate to reciprocate linearly on top of the filter screen, cleaning debris on the filter screen in a timely manner. This ensures smooth airflow during the drying process and avoids uneven drying or low efficiency caused by filter screen blockage, further improving printing quality and production efficiency.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figure 1-6As shown, a double-sided printing alignment calibration device for knitted fabric includes a base plate 1. Two mounting plates 2 are fixedly connected to the top left side of the base plate 1. A movable plate 3 is hinged to the top of the mounting plate 2. A motor 4 is fixedly connected to the front side of the front mounting plate 2. A drive gear 5 is fixedly connected to the output end of the motor 4. A driven gear 6 is meshed with the top of the drive gear 5. A winding shaft 7 is fixedly connected to the rear side of the driven gear 6. A fixing mechanism 8 is provided inside the mounting plate 2. A mounting box 9 is fixedly connected to the top center of the base plate 1. A control panel 10 is installed on the left side of the outside of the mounting box 9. A printing mechanism 11 is installed on the right side inside the mounting box 9. A guide roller group 12 is installed inside the mounting box 9 and to the left of the printing mechanism 11. A drying mechanism 13 is provided on the top left side of the mounting box 9. A correction mechanism 14 is installed on the top right side of the base plate 1. An unwinding mechanism 15 is installed on the top of the base plate 1 and to the right of the correction mechanism 14.

[0028] The fixing mechanism 8 includes a locking block 81, a housing 82, and a fixing rod 83. The top of the locking block 81 is fixedly connected to the bottom of the movable plate 3. The right side of the housing 82 is fixedly connected to the left side of the mounting plate 2. Both ends of the fixing rod 83 are fixedly connected to the inside of the mounting plate 2. A push rod 84 is slidably connected inside the housing 82. One end of the push rod 84 is fixedly connected to a fixing seat 85. Two sliders 86 are slidably connected in the middle of the fixing rod 83. An L-shaped insert 87 is fixedly connected to the right side of the sliders 86. Springs 88 are sleeved on both ends of the fixing rod 83. A connecting rod 89 is provided between the sliders 86 and the fixing seat 85.

[0029] It should be noted that when it is necessary to fix the movable plate 3, push the push rod 84 towards the outer casing 82. The push rod 84 drives the fixed seat 85 to move. The fixed seat 85 pushes the two sliders 86 to slide on the fixed rod 83 to both sides through the connecting rod 89, which drives the two L-shaped inserts 87 to move synchronously. Then, flip the movable plate 3 and insert the locking block 81 into the mounting plate 2. Then, release the push rod 84. Under the elastic force of the spring 88, the slider 86 drives the L-shaped inserts 87 to reset and insert into the locking block 81, thereby fixing the movable plate 3 firmly on the top of the mounting plate 2. When it is necessary to release the movable plate 3, repeat the above operation to release the restriction on the locking block 81. Then the movable plate 3 can rotate around the hinge at the top of the mounting plate 2, which is convenient for replacing the winding shaft 7 or performing other operations.

[0030] The drying mechanism 13 includes a receiving box 131, the bottom of which is fixedly connected to the top of the mounting box 9. A drying fan 132 is installed inside the receiving box 131. A filter screen 133 is fixedly connected to the top of the receiving box 131. A support plate 134 is fixedly connected to the front side of the receiving box 131. A second motor 135 is fixedly connected to the bottom of the support plate 134. A half gear 136 is fixedly connected to the output end of the second motor 135. A gear frame 137 is meshed with the outer side of the half gear 136. Three brush plates 138 are fixedly connected to the rear side of the gear frame 137. An air duct 139 is fixedly connected to the bottom of the receiving box 131.

[0031] It should be noted that during the drying process, the drying fan 132 starts, and the generated hot air is blown into the installation box 9 through the air duct 139 to dry the printed knitted fabric. At the same time, the motor 135 drives the half gear 136 to rotate. When the half gear 136 meshes with the teeth on one side of the toothed frame 137, it pushes the toothed frame 137 to slide to the left on the top of the support plate 134. The brush plate 138 on the back of the toothed frame 137 moves to the left accordingly. When the half gear 136 meshes with the teeth on the other side of the toothed frame 137, the toothed frame 137 drives the brush plate 138 to move to the right. This reciprocating motion causes the brush plate 138 to continuously wipe the top of the filter screen 133, promptly removing fibers, dust and other debris from the filter screen, ensuring smooth airflow during the drying process, improving drying efficiency and uniformity, and preventing dust from falling onto the knitted fabric.

[0032] like Figure 5 As shown, one end of the spring 88 is fixedly connected to the inside of the mounting plate 2, and the other end of the spring 88 is fixedly connected to the middle of the slider 86.

[0033] It should be noted that the spring 88 provides power for the reset of the slider 86, ensuring that the fixing mechanism 8 can quickly release the movable plate 3.

[0034] like Figure 5 As shown, the outer side of slider 86 and the outer side of L-shaped insert 87 are both slidably connected to the inside of mounting plate 2.

[0035] It should be noted that the mounting plate 2 provides guidance and support for the sliding of the slider 86 and the L-shaped insert 87, ensuring the stable operation of the fixing mechanism 8.

[0036] like Figure 5 As shown, the outer side of the card block 81 is slidably connected to the inside of the mounting plate 2, and the outer side of the L-shaped insert 87 is slidably connected to the inside of the card block 81.

[0037] It should be noted that the sliding engagement between the locking block 81 and the mounting plate 2, as well as the sliding engagement between the L-shaped insert block 87 and the locking block 81, makes the fixing and releasing process of the movable plate 3 smoother.

[0038] like Figure 5 As shown, one end of the connecting rod 89 is rotatably connected to the right side of the fixed seat 85, and the other end of the connecting rod 89 is rotatably connected to the left side of the slider 86.

[0039] It should be noted that the rotating connection method of the connecting rod 89 ensures that the movement of the fixed seat 85 can be smoothly transmitted to the slider 86, so that the two sliders 86 slide to both sides synchronously.

[0040] like Figure 6As shown, a limiting block 1310 is slidably connected to the outer side of the brush plate 138, and the bottom of the limiting block 1310 is fixedly connected to the top of the support plate 134.

[0041] It should be noted that the limiting block 1310 limits the sliding of the brush plate 138, ensuring that the brush plate 138 moves in a straight line in the horizontal direction and accurately wipes the filter screen 133.

[0042] like Figure 6 As shown, the bottom of the brush plate 138 abuts against the top of the filter screen 133, and the bottom of the toothed frame 137 is slidably connected to the top of the support plate 134.

[0043] It should be noted that the tight contact between the brush plate 138 and the filter screen 133 ensures effective cleaning of the filter screen 133, and the sliding fit between the toothed frame 137 and the support plate 134 makes the movement of the toothed frame 137 more stable.

[0044] The working principle of this utility model is as follows: When performing double-sided printing alignment calibration of knitted fabric, the knitted fabric roll is first installed on the unwinding mechanism 15. The fabric is drawn out from the unwinding mechanism 15, passes through the correction mechanism 14 and the mounting box, and is connected to the take-up shaft 7. The motor 4 is started, and the motor 4 drives the take-up shaft 7 to rotate through the driving gear 5 and the driven gear 6, thus pulling and winding the knitted fabric. The correction mechanism 14 monitors the running position of the fabric in real time. When the fabric is detected to be off-center, it automatically adjusts the position of the fabric to ensure that the fabric accurately enters the mounting box 9. After the fabric enters the mounting box 9, it reaches the printing mechanism 11, which prints on both sides of the fabric. After printing is completed, the fabric continues to move, guided by the guide roller group 12. Below the drying mechanism 13, the drying fan 132 starts, and hot air is blown onto the fabric through the air duct 139 to dry the printed area. At the same time, the motor 135 drives the half gear 136 to rotate. The half gear 136 meshes with the gear frame 137, causing the gear frame 137 to drive the brush plate 138 to make reciprocating linear motion on the top of the filter screen 133, cleaning the filter screen 133 and ensuring the drying effect. The dried fabric is led out from the mounting box 9 and reaches the take-up shaft 7. The take-up shaft 7 rolls up and stores the printed and dried fabric. When the take-up shaft 7 needs to be replaced, push the push rod 84 of the fixing mechanism 8 to disengage the L-shaped insert 87 from the locking block 81. The movable plate 3 rotates around the hinge to open the area where the take-up shaft 7 is located for easy operation. After the operation is completed, the movable plate 3 is fixed again and production continues.
