[0003] In the operation process of digital textile printing equipment, cloth needs to be stably and accurately conveyed on the guide tape to ensure that the printing pattern can be accurately printed on the cloth, and the guide tape cloth pressing platform device, as an important part of the cloth conveying system, mainly functions to press the cloth flat on the guide tape to prevent the cloth from wrinkling, deviating and other problems during conveying, thereby ensuring printing accuracy and effect.

[0004] For example, when printing high-speed pure cotton fabrics, if the pressure of the press roller cannot be increased synchronously with the speed of the guide tape, the edge of the cloth is prone to deviate due to insufficient friction, causing misalignment of continuous printing patterns, and ultimately forming a batch of defective products; and when processing elastic knitted fabrics, the traditional cloth pressing device is difficult to adapt to the stretching characteristics of the fabric due to fixed pressure, which easily leads to stretching deformation or local stacking of the printing area, affecting the quality of finished products.

[0007] In the scheme, the top rod is accelerated to rotate through the clamping block of the guide belt speed, the dial block and the arc block on the outer surface thereof are unfolded outward during the rotation process, the pressing rod below is dialled, the pressing rod exerts a certain pressure on the cloth pressing frame below, so that the pressure of the cloth pressing roller on the cloth can be increased, the occurrence of slipping can be reduced, and the stability during the cloth feeding process is improved; meanwhile, the rotation of the tension roller is driven through the No. two synchronous belt, the cloth below is formed with combing force towards both sides, and the vertical pressure of the cloth pressing roller is matched, so that the passing cloth can be kept in a flat state, and wrinkles and overlaps are reduced.

[0008] Preferably, the left and right side walls of the supporting frame are provided with a No. one lifting slot, a No. one sliding rod is fixedly connected between the upper and lower inner walls of the No. one lifting slot, the two ends of the cloth pressing frame are penetrated by the two No. one sliding rods on the two sides and are slidably connected with the No. one sliding rods, and a No. one spring is sleeved on the surface of the No. one sliding rod above the cloth pressing frame.

[0009] In actual application, the cloth pressing frame is attached to the cloth below under the pushing of the No. one spring, and can change the height following the thickness of the cloth, so that the cloth pressing frame can be always in contact with the cloth.

[0010] Preferably, the left and right inner walls of the supporting frame above the No. one lifting slot are provided with a No. two lifting slot, a No. two sliding rod is fixedly connected between the upper and lower inner walls of the No. two lifting slot, the two ends of the pressing rod are penetrated by the two No. two sliding rods on the two sides and are slidably connected with the No. two sliding rods, and a No. two spring is sleeved on the surface of the No. two sliding rod below the pressing rod.

[0011] In actual application, the pressing rod is lifted along the No. two lifting slot and is not in contact with the cloth pressing frame below under the pushing of the No. two spring, so that the cloth pressing frame is not pressed under the low speed state, and the normal pressure of the cloth pressing is not affected.

[0012] Preferably, a pressing roller is rotatably connected between the left and right inner walls of the pressing frame, and a support roller is rotatably connected between the left and right inner walls of the support frame below the pressing frame. The two ends of the support roller are respectively fixedly connected to one end of a connecting rod and the tail end of the drive shaft of a servo motor.

The synchronizing rod passes through the fixing plates and is rotatably connected to the synchronizing rod through the bearing seat.

[0017] In practical applications, the fixing plate plays a supporting role for the synchronizing rod, ensuring that the synchronizing rod can rotate normally without disengaging.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. This utility model uses the clamping block of the guide belt speed to accelerate the rotation of the top rod. During the rotation, the agitator block and arc block on its outer surface will unfold outward, agitating the extrusion rod below, so that the extrusion rod applies a certain pressure to the fabric pressing frame below, thereby increasing the pressure of the fabric pressing roller on the fabric, thus reducing slippage and improving the stability of the fabric feeding process.

[0020] 2. During the rotation of the top rod, the tension roller is driven to rotate by the second synchronous belt, which forms a combing force on the fabric below towards both sides. Combined with the vertical pressure of the pressure roller, the fabric can be kept flat, reducing wrinkles and overlaps, and improving the feeding efficiency and textile yield.

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0029] Example 1: A guide belt pressing platform device for digital textile printing equipment, see [link / reference] Figures 1 to 6The system includes a support frame 2, a top rod 4, and a pressing frame 7. Two rotating disks 14 are fixedly connected to the surface of the top rod 4. Six telescopic grooves 141 are arranged in a circular array on the outer wall of each rotating disk 14. Telescopic blocks 15 are slidably connected to the inner side of each telescopic groove 141. A No. 3 spring 142 is fixedly connected between the telescopic block 15 and the inner wall of the telescopic groove 141. A actuating disk 16 is fixedly connected to the outer end of each telescopic block 15. An arc-shaped block 161 is fixedly connected to the edge of the outer wall of the actuating disk 16. A pressing rod 9 is located below the actuating disk 16. When the top rod 4 rotates, it will... The two rotating disks 14 are driven to rotate. During the rotation, the telescopic block 15 in the telescopic groove 141 will move towards the opening of the telescopic groove 141 under the action of centrifugal force, causing the actuating disk 16 and the arc block 161 to move together. During the movement, they will gradually unfold and actuate the pressing rod 9 below. The pressing rod 9 is located above the pressing frame 7. After being actuated, it will have a downward force, which will squeeze the pressing frame 7 below, increase the pressure of the pressing roller 701 on the fabric, reduce the occurrence of slippage, and improve the stability of the feeding process.

[0030] It should be noted that the outer surfaces of the actuating disc 16 and the arc-shaped block 161 are very smooth, and the rotation speed of the push rod 4 is relatively fast. Therefore, the actuating disc 16 and the arc-shaped block 161 will quickly push the pressing rod 9. The arc-shaped block 161 has a certain elasticity, so it can deform slightly as the actuating disc 16 unfolds, blocking the gap between the two actuating discs 16. This reduces the interval impact when the pressing rod 9 is actuated, making the actuating disc 16 pass through the pressing rod 9 more smoothly and easily.

[0031] For example, the No. 3 spring 142 here can be customized using 60Si2MnA spring steel, which has a fatigue life of 5 million cycles (compared to only 2 million cycles for traditional 304 stainless steel springs), ensuring the stability of centrifugal adjustment under high-speed conditions.

[0032] Specifically, such as Figure 2 Both ends of the support roller 3 are fixedly connected to one end of the connecting rod 302 and the tail end of the drive shaft of the servo motor 301, respectively. The servo motor 301 is fixedly connected to the outer side wall of the support frame 2. The connecting rod 302 passes through the side wall of the support frame 2 and is rotatably connected to the support frame 2 through the bearing seat. The outer surface of the connecting rod 302 is fixedly connected to the inner ring of the bearing seat. The outer ring of the bearing seat is fixedly connected to the inside of the support frame 2. Therefore, it can be ensured that the connecting rod 302 rotates normally without detaching from the support frame 2. The top end of the support roller 3 contacts the bottom surface of the guide belt body 1, so it can support the guide belt body 1. While supporting, the speed of the guide belt body 1 can be adjusted, thereby controlling the feeding speed of the fabric.

[0033] Furthermore, such as Figure 1As shown, the other end of the connecting rod 302 is fixedly connected to a first gear 303, and one end of the push rod 4 passes through the side wall of the support frame 2 and is fixedly connected to a second gear 401. The second gear 401 is located directly above the first gear 303, and the first gear 303 and the second gear 401 are connected by a first synchronous belt 5. When the speed of the guide belt changes, the rotation speed of the support roller 3 and the connecting rod 302 changes, thereby changing the speed of the first gear 303. After the first gear 303 rotates, under the influence of the first synchronous belt 5, the second gear 401 and the push rod 4 will also rotate. The setting of the first synchronous belt 5 can avoid slippage and ensure that the push rod 4 can rotate stably without slippage.

[0034] It should be noted that the entire guide belt body 1 is supported by several support rollers 3. Only one of the support rollers 2 is shown here. The guide belt body 1 is moved by multiple support rollers 3 together, which ensures the stability of the guide belt body 1.

[0035] It is worth noting that, such as Figure 2 As shown, a lifting groove 201 is provided on both the left and right side walls of the support frame 2. A sliding rod 6 is fixedly connected between the upper and lower inner walls of the lifting groove 201. The two ends of the pressing frame 7 are respectively penetrated by the sliding rods 6 on both sides and slidably connected to the sliding rods 6. A spring 601 is sleeved on the surface of the sliding rod 6 above the pressing frame 7. The pressing frame 7 moves up and down along the lifting groove 201 and is always downward under the push of the spring 601, so that the pressing roller 701 can always be in contact with the fabric, thereby working together with the guide belt body 1 below to squeeze the fabric.

[0036] It is worth noting that, such as Figure 2 As shown, the support frame 2 above the first lifting groove 201 has second lifting grooves 202 on both the left and right inner walls. The upper and lower inner walls of the second lifting groove 202 are fixedly connected to the second sliding rod 8. The two ends of the extrusion rod 9 are respectively passed through the second sliding rod 8 on both sides and slidably connected to the second sliding rod 8. The surface of the second sliding rod 8 below the extrusion rod 9 is fitted with a second spring 801. The extrusion rod 9 is provided with a fabric pressing frame 7. The left and right inner walls of the fabric pressing frame 7 are rotatably connected to the fabric pressing roller 701. The support frame 2 below the fabric pressing frame 7 is rotatably connected to the left and right inner walls of the support frame 2. The extrusion rod 9 moves vertically along the second lifting groove 202. The second spring 801 below pushes and supports the extrusion rod 9 so that the extrusion rod 9 does not normally contact the fabric pressing frame 7. When the extrusion rod 9 is pushed downward, it will push and squeeze the fabric pressing frame 7 below, applying downward force. Together with the first spring 601, it applies downward force to the fabric pressing roller 701.

[0037] At the same time, such as Figure 3 and Figure 4As shown, the top rod 4 is rotatably connected between the left and right inner side walls of the support frame 2. Two fixing plates 203 are fixedly connected to the top edge of the support frame 2. The synchronizing rod 10 passes through the fixing plate 203 and is rotatably connected to the synchronizing rod 10 through the bearing seat. The outer surface of the synchronizing rod 10 is fixedly connected to the inner ring of the bearing seat, and the outer ring of the bearing seat is fixedly connected to the inside of the fixing plate 203, ensuring the stability of the synchronizing rod 10. The third gear 111 and the driven bevel gear 11 are respectively fixedly connected to the two ends of the synchronizing rod 10. The driven bevel gear 11 meshes with the driving bevel gear 402 fixedly sleeved on the surface of the top rod 4. Side frames 13 are fixedly connected to both ends of the side wall of the pressing frame 7. Tensioning rollers 131 are rotatably connected between the inner walls of the side frames 13. One end of the tensioning roller 131 is fixedly connected to A fourth gear 132 is connected to a third gear 111 via a second synchronous belt 12. As the top rod 4 rotates, the two driving bevel gears 402 on its surface drive their respective driven bevel gears 11 and the synchronous rod 10 to rotate. A second synchronous belt 12 is provided between the third gear 111 at the other end of the synchronous rod 10 and the fourth gear 132 below. The fourth gear 132 is connected to the tension roller 131. Therefore, driven by the second synchronous belt 12, the two tension rollers 131 on both sides are rotated. During the rotation of the tension rollers 131, they will move the fabric below, causing the fabric to unfold, minimizing wrinkles and overlaps, making the fabric feeding more stable and uniform, and improving the printing efficiency.

[0038] It's worth noting that digital textile printing equipment mainly includes pretreatment equipment, digital inkjet printers, and post-processing equipment. Pretreatment equipment (such as coating machines) coats the fabric with auxiliaries to optimize ink adsorption. Through padding or spraying processes, an auxiliary layer is formed on the fabric surface, enhancing ink penetration and color development. Digital inkjet printers (with piezoelectric or thermally heated printheads at their core) spray ink layer by layer onto the fabric according to digital files. They primarily convert image color separation data into electrical signals, driving the printheads to spray nano-sized ink droplets at high frequency, depositing ink as needed. Post-processing equipment removes excess dye through steam fixing and water washing to ensure color fastness and hand feel. Examples include steaming machines and washing machines. Both of these machines are post-processing equipment. Steaming machines use a humid and hot environment to induce a chemical reaction between dye molecules and fibers, while washing machines remove unfixed dyes and auxiliaries, ultimately completing the printing process.
