Description

Technical Field

[0001] This utility model relates to the field of cardboard dyeing technology, specifically to a dyeing device for processing colored cardboard. Background Technology

[0002] In the color card paper processing and production process, dyeing is a key process that determines the appearance quality and color stability of the color card paper, and the dyeing equipment, as the core equipment, directly affects the production efficiency and finished product quality of the color card paper.

[0003] Traditional dyeing equipment typically uses a rigid connection for limiting the position of the cardboard, and its height and position are fixed after the equipment is installed and debugged. It cannot be adaptively adjusted according to the dynamic changes in the dye depth in the dyeing tank. During the dyeing operation, the dye level fluctuates due to continuous consumption, evaporation, or replenishment. When the dye depth decreases, some areas of the cardboard may not be fully exposed to the dye, resulting in uneven dyeing, missed dyeing, and other defects. At the same time, since the position of the cardboard cannot be flexibly adjusted with the dye depth, in order to ensure that all cardboard is covered by dye, operators often need to fill the dye tank to a high level. This will cause uneven dye concentration in some areas due to poor dye circulation in the tank during the dyeing process, which will lead to color difference problems in the colored cardboard. In order to solve the above problems, an improved dyeing device for colored cardboard processing has been proposed. Utility Model Content

[0004] The purpose of this invention is to provide a dyeing device for color cardboard processing. By setting an adjustment mechanism and installing a positioning roller in the dyeing tank, the height and position of the positioning roller can be flexibly adjusted according to the dynamic changes in the depth caused by the consumption, volatilization or replenishment of dye, so as to adjust the cardboard limiting position. This flexible adjustment does not require filling the dye to a high liquid level, thereby reducing the probability of poor dye circulation caused by a high liquid level, so as to solve the problems mentioned in the background art.

[0022] 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.

[0023] This utility model provides, for example Figures 1-4 The dyeing device for color card paper processing shown includes a dyeing tank 1, with an inlet 2 and an outlet 3 respectively provided at the top of both ends of the dyeing tank 1, and guide rollers 4 installed at both ends of the inner cavity of the dyeing tank 1 through a connecting assembly 5.

[0024] It also includes an adjustment mechanism 6, which is installed on the inner wall of the dyeing pool 1 between the two guide rollers 4 at both ends. The adjustment mechanism 6 is equipped with a positioning roller 7 that provides a limit for the color card paper.

[0025] Stirring devices 8 are installed at equal intervals at the bottom of the inner cavity of dyeing pool 1. The stirring devices 8 are used to uniformly mix and stir the dye in dyeing pool 1.

[0026] Color card paper enters from the feed inlet 2 at the top of the dyeing tank 1, and is initially guided and conveyed by the guide rollers 4 installed by the connecting components 5 at both ends of the inner cavity of the dyeing tank 1. The adjustment mechanism 6 located between the two guide rollers 4 and on the inner wall of the dyeing tank 1 can change the height and position of the positioning rollers 7 on it by adjusting its own structure, thereby forming a precise limit on the color card paper and ensuring that the color card paper is in a position that matches the dye depth during the dyeing process. At the same time, after the stirring device 8, which is equidistantly set at the bottom of the inner cavity of the dyeing tank 1, is started, it will uniformly mix and stir the dye in the tank to avoid the dye concentration stratification. After the color card paper is dyed, it is output from the discharge port 3.

[0027] The guide roller 4 and the positioning roller 7 work together to achieve stable feeding and positioning of the color card paper, avoid card paper deviation and stacking during dyeing, and ensure dyeing continuity;

[0028] The adjustment mechanism 6 can dynamically adjust the position of the positioning roller 7 according to the dye depth, so that the paper can be fully dyed without excessive dye filling, reducing dye waste, and solving the problem of uneven dyeing and missed dyeing caused by the fixed position of the paper in traditional devices.

[0029] The stirring device 8 mixes the dye evenly, prevents uneven concentration in certain areas, effectively reduces color difference in the color card, and improves the dyeing quality.

[0030] A receiving tray 12 is installed at the feed inlet 2, a drain tray 9 is installed at the discharge outlet 3, and a water receiving tray 10 is installed below the drain tray 9.

[0031] Before entering the dyeing tank 1, the colored cardstock first falls onto the receiving tray 12. The receiving tray 12 serves to receive and initially organize the colored cardstock, preventing the subsequent guidance from being affected by the positional deviation of the cardstock when it enters. A drain tray 9 is installed at the discharge port 3. After the dyed colored cardstock is output from the dyeing tank 1, it first passes through the drain tray 9. The structure of the drain tray 9 allows excess dye on the cardstock to drip off naturally, and the dripping dye is collected by the receiving tray 10 below.

[0032] The feed inlet 2 and the receiving tray 12 can organize the paper to be dyed, ensuring that the paper enters the guide roller 4 smoothly and reducing dyeing deviation caused by feed offset.

[0033] The discharge port 3 and the drain tray 9 can remove excess dye from the cardboard, preventing dye from being carried out with the cardboard and causing waste, while also reducing the burden on subsequent drying processes.

[0034] The drip tray 10 collects dripping dye, enabling dye recycling and reuse, further reducing dye consumption, and keeping the surrounding environment of the device clean.

[0035] The adjustment mechanism 6 includes a card seat 61, which is fixed to the inner wall of the dyeing pool 1 and symmetrically arranged. Adjustment holes 62 are opened at equal intervals on the surface of the card seat 61. Positioning blocks 63 that cooperate with the card seat 61 are fixedly connected to both ends of the positioning roller 7. The positioning blocks 63 are engaged in the grooves opened in the card seat 61, and positioning holes 64 are opened on the positioning blocks 63 at positions corresponding to the adjustment holes 62. Positioning pins 65 are inserted into the adjustment holes 62 and the positioning holes 64. One end of the positioning pins 65 is engaged with a clamping strip 66.

[0036] The mounting base 61 of the adjustment mechanism 6 is fixed to the inner wall of the dyeing pool 1 and is symmetrically distributed. Adjustment holes 62 are equidistantly opened on the surface of the mounting base 61. The positioning blocks 63 at both ends of the positioning roller 7 are engaged in the grooves of the mounting base 61. When it is necessary to adjust the height of the positioning roller 7, the positioning block 63 is moved to the target position in the groove of the mounting base 61 so that the positioning hole 64 on the positioning block 63 is aligned with the corresponding adjustment hole 62 on the mounting base 61. Then, the positioning pin 65 is inserted into the adjustment hole 62 and the positioning hole 64 to fix it. Finally, the clamping strip 66 is used to clamp one end of the positioning pin 65 to prevent the positioning pin 65 from falling off, thereby completing the adjustment of the position of the positioning roller 7.

[0037] The adjustment mechanism 6 has a simple structure and is easy to operate. Through the cooperation of the positioning block 63 and different adjustment holes 62, the positioning roller 7 can be adjusted in multiple positions to accurately adapt to different dye depths and meet diverse dyeing needs.

[0038] The cooperation between the positioning pin 65 and the clamping strip 66 ensures that the positioning roller 7 is firmly fixed, preventing the paper from shifting due to the loosening of the positioning roller 7 during the dyeing process, and ensuring dyeing stability;

[0039] The equidistant adjustment holes 62 provide uniform adjustment levels for the positioning roller 7, improving adjustment accuracy and further ensuring dyeing uniformity.

[0040] The connecting component 5 includes a connecting block 51 and a fixing seat 52. The fixing seat 52 is fixed to the inner wall of the dyeing pool 1. The connecting block 51 is fixed to both ends of the guide roller 4. The connecting block 51 is snapped into the groove of the fixing seat 52. The surface of the connecting block 51 is provided with a through hole 53. The bottom of the fixing seat 52 is provided with a threaded hole 54 corresponding to the through hole 53. A positioning bolt 56 is inserted into the through hole 53 and threadedly connected to the threaded hole 54.

[0041] The fixing seat 52 of the connecting component 5 is fixed to the inner wall of the dyeing pool 1, and the connecting blocks 51 at both ends of the guide roller 4 are engaged in the grooves opened in the fixing seat 52. When installing the guide roller 4, the connecting blocks 51 are placed into the grooves of the fixing seat 52, so that the through holes 53 on the surface of the connecting blocks 51 are aligned with the threaded holes 54 at the bottom of the fixing seat 52. Then, the positioning bolts 56 are inserted into the through holes 53 and threadedly connected to the threaded holes 54. The connecting blocks 51 are fixed on the fixing seat 52 by the tightening force of the bolts, thereby realizing the installation and fixing of the guide roller 4. If it is necessary to disassemble or adjust the guide roller 4, simply loosen the positioning bolts 56.

[0042] The threaded connection makes the installation and disassembly of the guide roller 4 convenient, facilitates the maintenance and replacement of the guide roller 4 in the future, and reduces equipment maintenance costs;

[0043] The connection block 51 and the groove of the fixed seat 52 can initially position the guide roller 4. Combined with the fixing of the positioning bolt 56, it ensures that the guide roller 4 is firmly installed and avoids the guide roller 4 shaking during the dyeing process, which will affect the paper feeding.

[0044] The connecting component 5 also includes a limiting block 55, which is fixed to the upper end face of the positioning bolt 56. The lower surface of the limiting block 55 is attached to the upper surface of the connecting block 51, and the upper end of the positioning bolt 56 is engaged with the top of the fixing seat 52 through a protective pad.

[0045] A limiting block 55 is added to the connecting component 5. The limiting block 55 is fixed to the upper end face of the positioning bolt 56. When the positioning bolt 56 is tightened, the lower surface of the limiting block 55 is tightly attached to the upper surface of the connecting block 51, forming a longitudinal limit on the connecting block 51 and preventing the connecting block 51 from moving upward during the dyeing process. At the same time, the upper end of the positioning bolt 56 is engaged with the top of the fixing seat 52 through the protective pad. The protective pad fills the gap between the positioning bolt 56 and the top of the fixing seat 52, reducing the friction between the bolt and the fixing seat 52 and playing a certain buffering role.

[0046] The limiting block 55 further strengthens the fixation of the connecting block 51, preventing the connecting block 51 from shifting due to equipment vibration or paper jam conveying force, ensuring the stability of the guide roller 4 position, and improving the paper jam conveying accuracy.

[0047] The protective pad reduces frictional wear between the positioning bolt 56 and the fixed seat 52, extends the service life of the bolt and the fixed seat 52, and reduces noise during equipment operation.

[0048] Four measuring rods 11 are installed at symmetrical positions on the inner sidewall of the dyeing pool 1.

[0049] Four symmetrically distributed measuring rods 11 can accurately monitor the dye depth from different angles, avoiding misjudgment caused by errors in a single measuring point and improving the accuracy of dye depth monitoring.

[0050] Operators can quickly obtain dye depth information through measuring rod 11 without the need for additional measuring tools, providing a convenient reference for adjusting positioning roller 7, shortening adjustment time and improving production efficiency.

[0051] The stirring device 8 includes a drive motor 81, which is installed on the outer wall of the dyeing tank 1. The output shaft of the drive motor 81 passes through the dyeing tank 1 through a waterproof bearing and is connected to a stirring rod 82. Stirring blades 83 are arranged at equal intervals on the surface of the stirring rod 82.

[0052] The drive motor 81 of the stirring device 8 is installed on the outer wall of the dyeing tank 1. After the drive motor 81 is started, its output shaft passes through the dyeing tank 1 through a waterproof bearing (the waterproof bearing can prevent the dye from leaking from the penetration point), and drives the connected stirring rod 82 to rotate. The stirring blades 83, which are equidistantly arranged on the surface of the stirring rod 82, rotate synchronously with the stirring rod 82 to stir the dye in the dyeing tank 1 in all directions, so that the concentration of dye in each area is consistent.

[0053] The drive motor 81 provides stable power, which, together with the stirring rod 82 and the equidistant stirring blades 83, enables uniform stirring of the dye, completely solving the problems of poor dye circulation and uneven local concentration in traditional devices, and significantly reducing the color difference of the color card paper.

[0054] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
