Description

Technical Field

[0001] This utility model relates to the field of paper production technology, specifically to a paper printing device for paper processing. Background Technology

[0002] Printing refers to the process of imprinting patterns of varying shades onto the surface of various textiles, paper, or boards. Taking paper printing as an example, raised or recessed patterns are typically designed on the surface of rollers or deflectors. During operation, by applying pressure, the raised patterns on the rollers or deflectors are clearly imprinted onto the paper surface. After this printing process, the produced paper not only has a more aesthetically pleasing appearance but also a unique tactile texture. Furthermore, advertising slogans can be printed on the paper according to specific needs, thereby enhancing brand recognition and positively promoting the product.

[0003] Extensive searches revealed CN221698220U, which discloses a printing device including a base plate. Side plates are vertically arranged on both sides of the base plate, and a printing roller is rotatably arranged between the two side plates. A first motor for driving the printing roller to rotate is provided on the side wall of the side plate. A worktable is slidably arranged directly below the printing roller. A lifting assembly for driving the worktable to rise or fall is provided between the two side plates. A suction fan is mounted on the top of the two side plates, and a dust suction hood is provided on the output end of the suction fan. The opening of the dust suction hood is located on one side of the printing roller. A cleaning assembly for cleaning the outer surface of the printing roller is also provided between the printing roller and the dust suction hood.

[0004] Existing devices can clean detached fibers from paper during use. However, when dyeing processes are involved, traditional equipment struggles to achieve rapid dye curing, leading to prolonged surface drying time for printed paper. This lag directly impacts continuous paper winding efficiency, causing production line stoppages or speed reductions, ultimately limiting overall production efficiency. To address this bottleneck, this invention proposes an integrated paper printing device that enables simultaneous and efficient operation of printing and drying processes, thereby improving the continuity and production efficiency of paper processing. Utility Model Content

[0005] The purpose of this invention is to provide a paper printing device for paper processing, which has the advantages of simultaneous drying and efficient curing, and solves the problems of traditional printing equipment being unable to dry quickly when used with dyes, resulting in delayed paper winding and low production efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a paper printing device for paper processing, comprising a frame, on which a printing component is fixedly installed; the frame includes a base frame, on which a drying component is fixedly installed; on which an operating table is fixedly installed; and on which a discharge trough is provided on the upper surface of the operating table.

[0007] The printing assembly includes a mounting frame, in which a printing roller and a material feeding assembly are movably mounted at the front and rear ends respectively. A dye bin is fixedly mounted on the upper surface of the operating table below the front end of the printing roller. The dye bin contains a sponge block that absorbs dye, and the sponge block is in contact with the printing roller.

[0008] Preferably, the drying assembly includes a heater and a bracket for mounting the heater, the bracket being tightly connected to the base frame by mounting bolts.

[0009] In the design, the drying unit's warm air blower is fixedly mounted on the bracket and bolted to the base frame, achieving stable support and precise positioning of the drying unit. This structure ensures that the hot air outlet is always aligned with the discharge chute, providing a continuous and uniform heat source for curing the paper, avoiding the cumbersome process of adjusting the drying position required by traditional equipment.

[0010] Preferably, the discharge trough is located below the printing roller and the feeding assembly on opposite sides, and the width of the discharge trough matches the width of the paper to be printed.

[0011] In the design, by matching the width of the discharge chute of the operating table to the width of the paper and positioning it below the printing roller and the feeding assembly on opposite sides, precise constraints on the paper drying path are achieved. This structure allows the freshly printed paper to immediately enter the hot air coverage area, with no extra space on either side, effectively reducing heat loss and significantly improving dye curing efficiency.

[0012] Preferably, the mounting frame has a reserved groove and a reserved hole at its front and rear ends, respectively. The reserved groove adopts an elliptical structure design. Bearings are embedded in both the reserved groove and the reserved hole. The bearings in the reserved groove can slide in the horizontal direction. A vertical frame is fixedly installed on the mounting frame, and a mounting rod parallel to the printing roller is rotatably installed on the vertical frame.

[0013] In the design, dynamic adjustment of the printing roller pressure is achieved by creating an elliptical pre-reserved groove in the mounting bracket of the printing assembly and embedding a sliding bearing. This structure allows the bearing to move horizontally, flexibly adapting to paper of different thicknesses and ensuring uniform and controllable contact pressure between the printing roller and the feed roller.

[0014] Preferably, the inner front end of the reserved groove is provided with a threaded hole that passes through the front end of the mounting bracket. An adjusting bolt is installed in the threaded hole on the mounting bracket. The rear end of the adjusting bolt passes through the threaded hole and contacts the outer wall of the bearing in the reserved groove but is not fixedly connected.

[0015] In this design, the printing pressure is precisely adjusted by installing adjusting bolts in the pre-drilled slots of the mounting bracket to push against the outer wall of the bearing. This structure allows for minute changes in the position of the printing roller simply by rotating the bolts, eliminating the need to disassemble the equipment and significantly improving setup efficiency. It is particularly suitable for rapid switching between multiple batches with different process requirements.

[0016] Preferably, both ends of the printing roller are movably mounted in the reserved groove via bearings.

[0017] In the design, the pressure regulation and rotation functions are integrated by embedding the bearings at both ends of the printing roller into the reserved slots of the mounting frame for sliding. This structure allows the printing roller to maintain flexible rotation while adjusting the distance between it and the feed roller through bearing displacement, avoiding the pressure inability defects caused by traditional fixed installation methods.

[0018] Preferably, the material conveying assembly includes a material conveying roller, with both ends of the material conveying roller rotatably mounted in a reserved hole via bearings. The rear end of the material conveying roller passes through the reserved hole and is driven by a drive motor via a coupling. The drive motor is fixedly connected to the mounting frame.

[0019] In the design, the feed roller is directly driven by the drive motor of the feed assembly via a coupling, achieving stable control of the paper feed speed. This structure ensures that the feed roller and the printing roller have synchronized linear speeds, and together with the real-time drying of the warm air blower, a continuous production line of "printing-curing-discharging" is formed.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] This utility model achieves the effect of drying the printed paper simultaneously with the printing process by setting up a frame and fixing a drying component on the front of the frame's base, installing an operating table with a discharge trough on the top of the base, and setting a printing component on the frame. The printing component's mounting frame is equipped with a printing roller and a feeding component, and a dye bin is set on the operating table below the front end of the printing roller to hold a sponge block that absorbs dye and comes into contact with the printing roller.

[0022] The combination of the above components allows the printed paper to pass through the hot air covering area of ​​the drying component as it leaves the printing area and is discharged through the discharge chute. The hot air quickly cures the dye, achieving simultaneous drying and efficient curing. This avoids the problem of traditional printing equipment being unable to dry quickly when used with dyes, prevents undried ink from sticking together, avoids paper winding delays, and thus improves production efficiency, solving the problem of low production efficiency caused by traditional equipment.

Detailed Implementation

[0028] 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.

[0029] Example 1

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, one embodiment of the present invention is provided: a paper printing device for paper processing, including a frame 1, a printing component 3 fixedly installed on the frame 1, the frame 1 including a base frame 11, a drying component 2 fixedly installed on the front of the base frame 11, an operating table 12 fixedly installed on the top of the base frame 11, and a discharge trough 121 opened on the upper surface of the operating table 12.

[0031] The printing assembly 3 includes a mounting frame 33. The printing roller 31 and the material feeding assembly 32 are movably mounted at the front and rear ends of the mounting frame 33, respectively. A dye bin 13 is fixedly mounted on the upper surface of the operating table 12 below the front end of the printing roller 31. The dye bin 13 contains a sponge block 131 that absorbs dye, and the sponge block 131 is in contact with the printing roller 31.

[0032] Specifically, by setting up a frame 1 and fixing the drying component 2 on the front of the base frame 11 of the frame 1, and installing an operating table 12 with a discharge trough 121 on the top of the base frame 11, and setting up a printing component 3 on the frame 1, a printing roller 31 and a feeding component 32 are installed in the mounting frame 33 of the printing component 3, and a dye bin 13 is set up on the operating table 12 below the front end of the printing roller 31 to place a sponge block 131 with dye adsorbed in contact with the printing roller 31, the effect of drying the printed paper by using the drying component 2 is achieved while printing the paper.

[0033] The combination of the above components allows the paper to pass through the hot air coverage area of ​​the drying component 2 as it leaves the printing area and is discharged through the discharge chute 121. The hot air quickly cures the dye, achieving simultaneous drying and efficient curing. This avoids the problem of traditional printing equipment being unable to dry quickly when used with dyes, prevents undried ink from sticking together, avoids paper winding delays, and thus improves production efficiency, solving the problem of low production efficiency caused by traditional equipment.

[0034] Example 2

[0035] To achieve stable support and precise positioning of the drying components, such as Figure 1 and Figure 2 As shown, in this embodiment, the drying assembly 2 includes a heater and a bracket for mounting the heater. The bracket is tightly connected to the base frame 11 by mounting bolts.

[0036] In the design, the hot air blower of the drying component 2 is fixedly installed on the bracket and bolted to the base frame 11, achieving stable support and precise positioning of the drying component 2. This structure ensures that the hot air outlet is always aligned with the discharge chute 121, providing a continuous and uniform heat source for curing the paper, avoiding the cumbersome process of adjusting the drying position required by traditional equipment.

[0037] Furthermore, the discharge trough 121 is located below the printing roller 31 and the feeding assembly 32 on opposite sides, and the width of the discharge trough 121 matches the width of the paper to be printed.

[0038] In the design, by matching the width of the discharge trough 121 of the operating table 12 to the width of the paper and positioning it below the printing roller 31 and the feeding assembly 32 on opposite sides, precise constraints on the paper drying path are achieved. This structure allows the paper that has just finished printing to immediately enter the hot air coverage area, with no extra space on both sides, effectively reducing heat loss and significantly improving dye curing efficiency.

[0039] Furthermore, the mounting frame 33 has a reserved groove 332 and a reserved hole 331 at its front and rear ends, respectively. The reserved groove 332 adopts an elliptical structure design. Bearings 34 are embedded in both the reserved groove 332 and the reserved hole 331. The bearings 34 in the reserved groove 332 can slide in the horizontal direction. A stand 36 is fixedly installed on the mounting frame 33. A mounting rod 361 parallel to the printing roller 31 is rotatably installed on the stand 36.

[0040] In the design, by opening an elliptical pre-reserved groove 332 in the mounting bracket 33 of the printing assembly 3 and embedding a sliding bearing 34, dynamic adjustment of the pressure of the printing roller 31 is achieved. This structure allows the bearing 34 to move in the horizontal direction, which can flexibly adapt to paper of different thicknesses and ensure that the contact pressure between the printing roller 31 and the feed roller 323 is uniform and controllable.

[0041] Furthermore, a threaded hole is provided at the front end of the inner side of the reserved groove 332, which passes through the front end of the mounting bracket 33. An adjusting bolt 35 is installed in the threaded hole on the mounting bracket 33. The rear end of the adjusting bolt 35 passes through the threaded hole and contacts the outer wall of the bearing 34 in the reserved groove 332 but is not fixedly connected.

[0042] In the design, the printing pressure is precisely adjusted by installing adjusting bolts 35 in the pre-reserved slots 332 and screw holes of the mounting bracket 33 to push the outer wall of the bearing 34. This structure allows for slight changes in the position of the printing roller 31 by rotating the bolts, without disassembling the equipment, significantly improving debugging efficiency and making it particularly suitable for rapid switching between different processes in multiple batches.

[0043] Example 3

[0044] To achieve the integration of printing roller pressure adjustment and rotation functions, such as Figure 3 and Figure 4 As shown, in this embodiment, the two ends of the printing roller 31 are movably installed in the reserved groove 332 through bearings 34.

[0045] In the design, the pressure regulation and rotation functions are integrated by embedding the bearings 34 at both ends of the printing roller 31 into the reserved slots 332 of the mounting frame 33 in a sliding structure. This structure allows the printing roller 31 to maintain flexible rotation while adjusting the distance between it and the feed roller 323 through the displacement of the bearings 34, avoiding the defect of unadjustable pressure caused by traditional fixed installation methods.

[0046] Furthermore, the material conveying assembly 32 includes a material conveying roller 323. Both ends of the material conveying roller 323 are rotatably installed in the reserved hole 331 through bearings 34. The rear end of the material conveying roller 323 passes through the reserved hole 331 and is driven by a drive motor 321 through a coupling 322. The drive motor 321 is fixedly connected to the mounting bracket 33.

[0047] In the design, the feed roller 323 is directly driven by the drive motor 321 of the feed assembly 32 via the coupling 322, thus achieving stable control of the paper feed speed. This structure ensures that the feed roller 323 and the printing roller 31 are synchronized in linear speed, and together with the real-time drying of the warm air blower, a continuous production line of "printing-curing-discharging" is formed.

[0048] In use, a sponge block 131 with sufficient dye adsorption is placed in the dye chamber 13 to ensure full contact between the sponge block 131 and the surface of the printing roller 31. By rotating the adjusting bolt 35, the bearing 34 in the reserved groove 332 is pushed to slide horizontally, and the pressure between the printing roller 31 and the feed roller 323 is finely adjusted to ensure that the paper is pressed evenly.

[0049] Start the drive motor 321 of the feeding assembly 32, which drives the feeding roller 323 to rotate counterclockwise via the coupling 322. Start the warm air blower to deliver hot air to the bottom of the discharge trough 121 and set the temperature to the range required for dye curing.

[0050] The roll of paper to be printed is inserted onto the mounting rod 361, and a section is led out from the rear end of the feed roller 323. The paper moves forward under the friction of the feed roller 323 and enters the gap between the printing roller 31 and the feed roller 323. The raised pattern on the surface of the printing roller 31 picks up the dye on the sponge block 131, and the pattern is transferred to the surface of the paper by the contact pressure with the paper.

[0051] After the paper leaves the printing area, the printed and dried paper is discharged through the discharge chute 121. The width of the discharge chute 121 matches the paper to ensure that the paper is conveyed straight and can pass through the air outlet of the hot air blower. The hot air quickly cures the dye and prevents the undried ink from sticking together.

[0052] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
