[0002] Current sizing methods primarily utilize traditional rotary screens, flat screens, stenters, and specialized large-scale sizing equipment. After sizing, the printing process involves drying and rolling the sizing material for later use. Newer wet printing solutions involve simultaneous sizing and printing, using single or double sets of rotary screens, which are space-consuming and expensive. Flat screen sizing, due to its squeegee printing method, is unsuitable for wet printing. Stenters and other sizing equipment are also large, expensive, and space-consuming. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a digital printing wet printing sizing device. This device integrates the sizing roller, pressure roller, and adjusting roller onto an adjustable mounting frame.

Combined with the stable support of the frame, it ensures a continuous and stable sizing process. Its compact design saves space and is suitable for use with continuous and scanning digital printing equipment, effectively reducing equipment investment and operating costs in the sizing process and improving the adaptability and production efficiency of wet printing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This utility model discloses a digital printing wet printing sizing device, including a frame, a sizing tank installed in the middle of the frame, a sizing roller and a pressure roller rotatably arranged inside the frame, a part of the sizing roller being located in the sizing tank, and the pressure roller being arranged above the sizing roller. It also includes a drive motor that drives and connects to the sizing roller, a guide roller rotatably arranged on the frame, an export roller rotatably arranged on the frame, the export roller being arranged higher than the pressure roller, and two inlet rollers rotatably arranged on the frame, the inlet rollers being installed at a height lower than the sizing tank.

[0006] Furthermore, the output roller includes two output rollers, which are located on the left and right sides of the pressure roller, respectively.

[0007] Furthermore, a lifting mechanism or a swing mechanism is installed on the frame, and one of the export rollers is installed on the lifting mechanism or the swing mechanism.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-2 As shown, a digital printing wet printing sizing device includes a frame 1, which includes a first support frame 11 and a second support frame 12. Several crossbeams 13 are connected between the first support frame 11 and the second support frame 12. Figure 5 As shown, the frame 1 can also be assembled from a support plate 15 and a crossbeam 13. The support plate 15 can be a whole piece of laser-cut plate.

[0026] A pulp trough 2 is installed in the middle of the frame 1, with its two ends fixed to support frame 11 and support frame 12, respectively. The pulp trough 2 is made of stainless steel. An feeding roller 3 and a pressure roller 4 are rotatably mounted inside the frame 1, with the pressure roller 4 positioned above the feeding roller 3. The pulp trough 2 contains pulp, and half of the feeding roller 3 is located within it. The feeding roller 3 is a hard roller with uniformly etched patterns, and the pressure roller 4 is a rubber roller. The device also includes a drive motor that drives the feeding roller 3; the speed of the drive motor is adjustable.

[0027] This device also includes an adjusting roller 9 rotatably mounted on the frame 1. The adjusting roller 9 is a plastic-coated steel roller, which makes it difficult for the sizing agent to adhere to the adjusting roller 9. The adjusting roller 9 can remove excess sizing agent from the surface of the sizing roller 3. A mounting frame 14 is mounted on the support frame 11 and the support frame 2 12, and the sizing roller 3, the pressure roller 4, and the adjusting roller 9 are rotatably mounted on the mounting frame 14. A displacement mechanism is mounted on the mounting frame 14. The displacement mechanism drives the pressure roller 4 and the adjusting roller 9. The displacement mechanism can drive the pressure roller 4 to move up and down, and can also drive the adjusting roller 9 to move along the line connecting the centers of the sizing roller 3 and the adjusting roller 9. The displacement mechanism is a cylinder, and the piston rod of the cylinder is connected to a rotating seat connected to both ends of the pressure roller 4 and the adjusting roller 9. The position of the rotating seat is adjusted by controlling the extension and retraction of the piston rod by the cylinder, thereby adjusting the distance between the pressure roller 4, the adjusting roller 9, and the sizing roller 3 respectively. By adjusting the distance between the pressure roller 4 and the sizing roller 3, the pressure on the fabric can be adjusted, so that the sizing agent can better penetrate into the fabric to complete the sizing process. By adjusting the distance between the adjusting roller 9 and the sizing roller 3, the amount of sizing material remaining on the sizing roller 3 can be controlled, thereby controlling the amount of sizing applied to the fabric. At the same time, the adjusting roller 9 can also spread the sizing material on the sizing roller 3 evenly, making the sizing material distribution on the sizing roller 3 uniform.

[0028] A guide roller 6, which is an expansion roller, is rotatably mounted on the frame 1 and is positioned above the adjusting roller 9. An export roller is also rotatably mounted on the frame 1, positioned higher than the pressure roller 4. Two import rollers 5 are also rotatably mounted on the frame 1, with their installation height lower than the paste tank 2. The fabric is introduced into the frame 1 by the import rollers 5 and guided by the guide rollers 6 to the area between the sizing roller 3 and the pressure roller 4. The pressure roller 4 presses the fabric onto the sizing roller 3. During its rotation, the sizing roller 3 transfers the paste from the paste tank 2 onto the fabric, thus completing the sizing process. The sizing fabric is then guided out by the export rollers and enters the subsequent digital printing equipment.

[0029] The height of the guide roller 6 is between the pressure roller 4 and the sizing roller 3. The highest point of the outer periphery of the guide roller 6 is higher than the highest point of the outer periphery of the adjusting roller 9. This allows the fabric to be guided downwards by the guide roller 6 without contacting the adjusting roller 9, and to enter between the sizing roller 3 and the pressure roller 4. This arrangement allows the fabric to bypass the pressure roller 4, that is, the back of the fabric is in contact with the outer periphery of the pressure roller 4. Thus, the movement of the pressure roller 4 can move the fabric closer to or away from the sizing roller 3, ensuring appropriate pressure.

[0030] The guide roller includes two guide rollers 7, located on the left and right sides of the pressure roller 4, respectively. A lifting mechanism 8 or a swing mechanism is mounted on the frame 1. One of the guide rollers 7 is mounted on the lifting mechanism 8 or the swing mechanism. The lifting mechanism 8 drives the guide roller 7 to move up and down, while the swing mechanism drives the guide roller 7 to move left and right. The guide roller 7 mounted on the lifting mechanism 8 or the swing mechanism is equipped with a tension sensor. The tension sensor senses the tension on the fabric, and then the lifting mechanism 8 adjusts the up-and-down movement of the guide roller 7, or the swing mechanism drives the guide roller 7 to move left and right, thus tauting the fabric.

[0031] like Figure 3 , Figure 4 As shown, the guide rollers include guide roller 7 and guide roller 10. One guide roller 7 is provided, located on the side closer to the fabric feeding direction. Two guide rollers 10 are provided, positioned near the top of the frame 1. Guide rollers 10 extend the time the fabric moves on the frame 1 after sizing, allowing more time for the sizing agent to penetrate the fabric, resulting in better sizing. A lifting mechanism 8 or a swing mechanism is installed on the frame 1, and at least one guide roller 10 is mounted on the lifting mechanism 8 or the swing mechanism. The guide roller 10 mounted on the lifting mechanism 8 or the swing mechanism is equipped with a tension sensor. The tension sensor senses the tension on the fabric, and then the lifting mechanism 8 adjusts the vertical movement of the guide roller 10, or the swing mechanism drives the guide roller 10 to move left and right, thus tauting the fabric.

[0032] Inlet roller 5, guide roller 6, outlet roller 1 7, and outlet roller 2 10 are rollers made of hard materials.

[0033] like Figure 6 As shown, the lifting mechanism 8 includes a lead screw motor 16, a lead screw 17, a lead screw slider 18, a guide bar 19, and a guide block 20. The lead screw motor 16 and the guide bar 19 are mounted on the frame 1. The lead screw motor 16 drives the lead screw 17, the lead screw slider 18 is mounted on the lead screw 17, and the guide block 20 is slidably mounted on the guide bar 19. The guide block 20 and the lead screw slider 18 are arranged opposite to each other. The first guide roller 7 and the second guide roller 10 can be installed between the guide block 20 and the lead screw slider 18. By driving the lead screw 17 to rotate through the lead screw motor 16, the lead screw slider 18 moves up and down. The guide block 20 moves on the guide bar 19 through the first guide roller 7 and the second guide roller 10, thereby realizing the up and down movement of the first guide roller 7 and the second guide roller 10 and tensioning the fabric.

[0034] like Figure 7As shown, the swing mechanism includes swing arms 21, one end of which is rotatably connected to the frame 1. Two swing arms 21 are provided and are arranged opposite each other on the frame 1. A first guide roller 7 and a second guide roller 10 are installed between the two swing arms 21. The swing mechanism also includes a hydraulic cylinder 22, the bottom of which is hinged to the frame 1. A connecting rod 23 is installed on the piston rod of the hydraulic cylinder 22, and the end of the connecting rod 23 away from the hydraulic cylinder 22 is hinged to one of the swing arms 21. The hydraulic cylinder 22 drives the piston rod to extend and retract, which in turn drives the swing arms 21 to swing via the connecting rod 23, thereby adjusting the position of the first guide roller 7 and the second guide roller 10 installed on the swing arms 21, so that the first guide roller 7 and the second guide roller 10 tension the fabric.

[0035] like Figure 8 As shown, the first guide roller 7 and the second guide roller 10 are mounted on the lifting mechanism 8 via mounting components. The mounting components include a mounting base 24, which is mounted on the guide block 20 and the lead screw slider 18. A mounting groove 26 is provided within the mounting base 24, allowing the support seats 25 at the shaft ends of the first guide roller 7 and the second guide roller 10 to be inserted into the mounting groove 26. The mounting groove 26 limits the movement of the support seats 25, restricting their left and right movement. A limiting screw 30 is threaded onto the mounting base 24. The portion of the limiting screw 30 extending into the mounting groove 26 abuts against the upper surface of the mounting base 25, thereby fixing the support seats 25 within the mounting base 24, thus completing the installation of the first guide roller 7 and the second guide roller 10.

[0036] The mounting base 24 has a connecting hole 27 on one side, which is connected to the mounting groove 26. The shafts of the first guide roller 7 and the second guide roller 10 can pass through the connecting hole 27.

[0037] The bottom of the mounting groove 26 is connected to a positioning cone 28, and the bottom of the support base 25 has a positioning hole 29 that mates with the positioning cone 28. When the support base 25 is installed into the mounting groove 26, the positioning cone 28 can be inserted into the positioning hole 29, thereby limiting the support base 25 and restricting its forward and backward movement, thus ensuring the firmness of the support base 25 installation.

[0038] The diameter of the positioning cone 28 gradually increases from top to bottom, with a smaller diameter at the upper end, making it easier to insert into the positioning hole 29. Even when there is a certain deviation between the center of the positioning hole 29 and the center of the positioning cone 28, the upper end of the positioning cone 28 can still be inserted into the positioning hole 29, guiding and correcting the support 25 during the insertion process.

[0039] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
