Technical Field

[0001] This utility model relates to the field of impregnation and drying technology, specifically to an impregnation and drying device that facilitates the replacement of paper rolls. Background Technology

[0002] Impregnated paper is one of the main materials for decorative paper. Currently, domestic impregnated paper production equipment includes vertical impregnation dryers, horizontal impregnation dryers, and hybrid impregnation dryers. All types of impregnation dryers consist of an impregnation unit and a drying chamber.

[0003] In the existing technology, paper rolls are placed in slots by a forklift, and the paper rolls are rotated to enter the impregnation dryer. When using a forklift to place the paper rolls, the spindle of the paper roll needs to be aligned with the slot before it can be put in, which results in slow replacement speed and low efficiency.

[0004] Based on this, the present invention designs an impregnation and drying device that facilitates the replacement of paper rolls to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an impregnation and drying device that facilitates the replacement of paper rolls.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-4 An impregnation and drying apparatus for easy paper roll replacement includes a base 100 and an impregnation and drying machine 200. The base 100 is located on one side of the feed inlet of the impregnation and drying machine 200. A paper roll replacement mechanism 300 is provided on the base 100 to facilitate paper roll replacement and improve the impregnation and drying speed. The paper roll replacement mechanism 300 includes a movable guide rail 313 and a fixed slide rail 311 disposed above the base 100. The paper roll is placed above the movable guide rail 313 and a rotating shaft 331 is inserted into the paper roll. A limiting groove corresponding to the rotating shaft 331 is formed between the movable guide rail 313 and the fixed slide rail 311. The movable guide rail 313 is symmetrically arranged from narrow to wide, and limiting rings 332 are symmetrically arranged on the surface of the rotating shaft 331. The narrowest distance of the movable guide rail 313 is greater than the width of the paper roll.

[0027] In this embodiment of the utility model, the forklift inserts the rotating shaft 331 along with the paper roll, places the rotating shaft 331 on top of the moving guide rail 313, so that the paper roll is between the two moving guide rails 313, and pushes the paper roll toward the impregnation dryer 200. Since the moving guide rail 313 is set from narrow to wide, during the movement of the paper roll, the distance between the limiting ring 332 and the side of the moving guide rail 313 gradually decreases until the limiting ring 332 contacts the moving guide rail 313, completing the positioning of the paper roll. The paper roll moves as needed until it falls into the limiting groove, completing the installation of the paper roll.

[0028] In this embodiment of the utility model, the rotating shaft 331 is gradually limited by the setting of two moving guide rails 313 that gradually widen until the limiting ring 332 fits against the side wall of the moving guide rail 313, so that the rotating shaft 331 is in the middle of the two moving guide rails 313, thus completing the positioning of the paper roll. This facilitates the installation of the paper roll without the need for a forklift to drive the paper roll for precise positioning, thereby improving the speed and convenience of paper roll replacement.

[0029] It should be noted that the rate at which the moving guide rail 313 changes from narrow to wide in this application determines the speed of paper roll positioning. A faster rate of change from narrow to wide results in a faster positioning speed, but also a greater impact force on the moving guide rail 313 and the limiting ring 332. Conversely, the opposite applies. Users can choose according to their actual needs.

[0030] In some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment of the present invention, a fixing plate 314 is symmetrically arranged on the top of the base 100. A power roller 316 is rotatably connected to the side of the fixing plate 314 near the moving guide rail 313. A motor 315 is fixedly installed on the other side of the fixing plate 314. The output shaft end of the motor 315 is fixedly connected to the power roller 316.

[0031] In this embodiment of the invention, a fixing plate 314 is used to install a motor 315 and a drive roller 316. The motor 315 drives the drive roller 316 to rotate, which in turn causes the rotating shaft 331 to rotate, thereby rotating the paper roll for impregnation and drying. The upper part of the surface of the drive roller 316 is in contact with the lower part of the surface of the rotating shaft 331, and the friction causes the rotating shaft 331 to drive the paper roll to rotate.

[0032] In this embodiment of the utility model, by Figure 2 As shown, the power roller 316 is disposed within the limiting groove between the moving guide rail 313 and the fixed slide rail 311, and the power roller 316 is fitted against the rotating shaft 331. The power roller 316 and the limiting groove limit the rotating shaft 331, preventing it from disengaging from the limiting groove. The limiting groove and the power roller 316 are correspondingly positioned to avoid mutual interference, and the two power rollers 316 rotate in the same direction, ensuring synchronous rotation of the paper roll.

[0033] In this embodiment of the invention, a support frame 310 is fixedly connected to the bottom of the fixed slide rail 311, and the support frame 310 is fixedly connected to the top of the base 100. A fixed frame 312 is rotatably connected to one side of the movable guide rail 313, and the fixed frame 312 is fixedly connected to the top of the base 100. Electric push rods 321 are symmetrically arranged on the top of the base 100, and the telescopic end of the electric push rod 321 is rotatably connected to the bottom of the movable guide rail 313. The telescopic movement of the electric push rod 321 drives the movable guide rail 313 to rotate along the fixed frame 312, thereby giving the movable guide rail 313 a certain slope. Under the action of gravity, the rotating shaft 331 and the paper roll move towards the impregnation dryer 200, achieving automatic positioning without pushing the paper roll, further facilitating the installation and replacement of the paper roll.

[0034] In this embodiment of the invention, the spacing of the limiting rings 332 is the same as the farthest distance of the wide side of the moving guide rail 313, and the limiting rings 332 have rounded corners on the side near the paper roll. The outer side of the moving guide rail 313 also has rounded corners, and a wear-resistant layer is provided on the surface of the moving guide rail 313. By setting the rounded corners, the moving guide rail 313 gradually comes into contact with the limiting rings 332. The paper roll drives the rotating shaft 331 to move on the moving guide rail 313. As it moves toward the impregnation dryer 200, the moving guide rail 313 gradually widens, thereby gradually reducing the spacing between the limiting rings 332 and the moving guide rail 313, so that the limiting rings 332 gradually come into contact with the outer wall of the moving guide rail 313 until they are in contact, at which point the positioning of the paper roll is completed.

[0035] It should be noted that the wear-resistant layer is a 0.2-0.5mm tungsten carbide coating to improve wear resistance.

[0036] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
