DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-Figure 7 As shown, the present invention provides the following technical solutions: an efficient printing, drying, laminating and rolling wallpaper integrated machine, comprising a printing component 1, a drying component 2, a laminating component 3 and a winding drum 4 arranged in sequence along the wallpaper forward direction;

[0033] The drying component 2 adopts a bidirectional drying structure, and the wallpaper passes through the drying component 2 in the forward direction after being printed by the printing component 1; a reversing mechanism 5 is provided between the film pressing component 3 and the winding drum 4, and the wallpaper passes through the drying component 2 in the reverse direction after being reversed by the reversing mechanism 5.

[0034] Preferably, the reversing mechanism 5 includes two guide rollers that cooperate with each other, and one of the guide rollers cooperates with the film pressing assembly 3 to extrude the wallpaper.

[0035] From the above, it can be seen that the all-in-one machine provided by the present invention integrates the functions of printing, printing drying, laminating, laminating drying and winding, thereby effectively realizing the efficient production of wallpaper; and the printing drying and laminating drying are performed by the same drying component 2, thereby making the structure of the overall all-in-one machine more reasonable.

[0036] For the specific structure of the printing assembly 1, please refer to Figure 1 As shown:

[0037] The printing assembly 1 includes a printing roller 13, an ink cartridge 12 for supplying ink to the printing roller 13, and two limiting rollers 11 pressed tightly on both sides of the printing roller 13. When the wallpaper is printed, it passes through the gap between the two limiting rollers 11 and the printing roller 13 in sequence.

[0038] Specifically, two limiting rollers 11 are used to press the wallpaper tightly, so that the wallpaper can be in close contact with the printing roller 13 during printing, thereby ensuring the printing quality and avoiding the problems of missing printing and lack of printing.

[0039] For the specific structure of the drying component 2, please refer to Figure 2-Figure 4 As shown:

[0040] The drying component 2 includes a drying box 21, and a drying plate 22 and an airflow drying cylinder 23 installed in the drying box 21. The drying plate 22 realizes drying of the wallpaper when it passes through the drying component 2 in the forward direction, and the airflow drying cylinder 23 realizes drying of the wallpaper when it passes through the drying component 2 in the reverse direction.

[0041] Among them, as a preferred embodiment, the drying plate 22 adopts a resistance heating metal plate, and one end of the drying plate 22 is rotatably installed in the drying box 21 through a rotating shaft. A rotating motor 24 is fixed on the outer wall of one side of the drying box 21, and the rotating motor 24 drives the drying plate 22 to rotate in the drying box 21.

[0042] Specifically, the principle of the drying plate 22 performing forward printing drying is as follows:

[0043] As can be seen from the figure, when the printed wallpaper enters the drying box 21, its printed surface faces the drying plate 22. The drying plate 22 generates heat based on resistance heating, thereby drying the wallpaper and the printing ink thereon. In the plate-type drying structure, the closer the distance between the drying structure and the object to be dried, the higher the heat received by the object to be dried, and the corresponding drying speed is faster. However, in the process of printing wallpaper, the printing amount at different positions is different, so the degree of drying and heating of the wallpaper needs to be adjusted according to the amount of printing. In the present invention, a rotating drying plate 22 is used to adjust the distance between the drying plate 22 and the wallpaper, thereby achieving the effect of adjusting the degree of drying and heating of the wallpaper.

[0044] For example, Figure 2 In the embodiment, the drying plate 22 is in a horizontal state. At this time, all positions on the drying plate 22 are closest to the wallpaper. In this state, when the wallpaper is transported from left to right, the degree of heating is at its maximum. Therefore, it is suitable for drying positions with a large amount of printing. When the rotating motor 24 is started, the drying plate 22 can be driven to rotate clockwise, thereby Figure 2 The right side of the middle drying plate 22 is away from the wallpaper. In this state, when the wallpaper is transported from left to right, the degree of heat gradually decreases, which can be effectively applied to the drying of the reduced printing volume. In summary, the rotation of the drying plate 22 can effectively adapt to the printing drying under different requirements, and the driving is convenient, and there is no need to repeatedly adjust the heating power of the drying plate 22, thereby ensuring the service life of the drying plate 22.

[0045] Among them, as a preferred embodiment, at least three airflow drying cylinders 23 are provided, all of which are rotatably installed in the drying box 21, and the wallpaper passes through the gaps between at least three airflow drying cylinders 23 in sequence when passing through the drying component 2 in the reverse direction; the airflow drying cylinder 23 is a hollow cylinder, and a plurality of first air holes 25 are evenly opened on the cylinder wall of the airflow drying cylinder 23, an exhaust fan 27 is fixed on the outer wall of one side of the drying box 21, and the air inlet of the exhaust fan 27 is connected to one end of the airflow drying cylinder 23.

[0046] Furthermore, both ends of the airflow drying cylinder 23 are rotatably connected to fixed shafts 26 through rotating bearings. The two fixed shafts 26 are fixed on the inner wall of the drying box 21, and one of the fixed shafts 26 is a hollow shaft and passes through the drying box 21. The air inlet of the exhaust fan 27 is connected to the hollow shaft.

[0047] As can be seen from the above, the principle of using the airflow drying cylinder 23 to achieve reverse film pressing and drying is:

[0048] As can be seen from the figure, when the wallpaper is transferred to the winding drum 4, friction is generated with the airflow drying drum 23, and the airflow drying drum 23 can rotate synchronously based on the setting of the rotating bearing, and at the same time, the exhaust fan 27 is started, thereby realizing the exhaust of air in the drying box 21 through the airflow drying drum 23; specifically, due to the above-mentioned forward drying operation, the gas temperature in the drying box 21 is roughly the same as the temperature of the drying plate 22, so the flow of hot air flow can effectively achieve the drying effect;

[0049] Depend on Figure 2 It can be seen that when the airflow in the drying box 21 flows toward the airflow drying cylinder 23, it will pass through the surface of the wallpaper, thereby forming a primary drying of the wallpaper; and after the airflow passes through the first air hole 25 and flows into the airflow drying cylinder 23, it will cause the temperature of the airflow drying cylinder 23 itself to rise, so when the wallpaper is transmitted around the airflow drying cylinder 23, it will form a secondary drying.

[0050] In summary, the bidirectional drying of the drying component 2 is effectively achieved.

[0051] For the specific structure of the film pressing assembly 3, please refer to Figure 5-Figure 7 As shown:

[0052] Among them, as an implementation method, the film pressing assembly 3 includes a fixed inner cylinder 33 and a rotating outer cylinder 31, and connecting bearings 32 are provided at both ends of the rotating outer cylinder 31, and the two connecting bearings 32 are both sleeved on the fixed inner cylinder 33 to achieve rotational coordination between the fixed inner cylinder 33 and the rotating outer cylinder 31.

[0053] Preferably, the fixed inner cylinder 33 is a hollow cylinder with an opening at one end and capable of guiding air inward, a plurality of second air holes 35 are evenly provided on the cylinder wall of the fixed inner cylinder 33, and the second air holes 35 are located between the two connecting bearings 32, an annular air cavity 34 is formed between the fixed inner cylinder 33 and the rotating outer cylinder 31, a plurality of inclined holes 36 are evenly provided on the cylinder wall of the rotating outer cylinder 31, and the inclined holes 36 guide air from the side where the film has been pressed to the side where the film has not been pressed.

[0054] Preferably, an air guide mechanism is connected between the drying assembly 2 and the film pressing assembly 3 , and the air guide mechanism includes a branch pipe connected to the air outlet of the exhaust fan 27 , and an air guide pipe 28 connecting the branch pipe and the fixed inner cylinder 33 .

[0055] In summary, it can be seen that the airflow extracted by the exhaust fan 27 is not discharged directly, but is sent to the film pressing assembly 3 through the branch pipe and the air guide pipe 28, thereby achieving the effect of improving the film pressing quality.

[0056] Specifically, when the airflow enters the film pressing assembly 3, it first enters the fixed inner cylinder 33, then disperses into the annular air cavity 34 through the second air hole 35, and finally is evenly discharged through the inclined hole 36; Figure 6 As shown, when the inclined hole 36 discharges the airflow, the airflow direction flows from the film-pressed side to the un-film-pressed side, thereby squeezing the pressed film and the wallpaper at a certain angle, thereby effectively squeezing out the air between the film and the wallpaper, making the film close to the wallpaper surface, thereby achieving the purpose of reducing film pressing bubbles; in addition, the airflow is guided out from the drying component 2 through the air guide mechanism, so the airflow has a certain temperature, thereby increasing the temperature of the outside of the rotating outer cylinder 31, thereby achieving the effect of hot film pressing and further ensuring the film pressing quality.

[0057] Also, see Figure 1 As shown, the all-in-one machine provided by the present invention also includes a base 6, and the printing component 1, the drying component 2, the laminating component 3 and the reversing mechanism 5 are all fixed to the top of the base 6 in sequence through a support frame, and the winding drum 4 is fixed to the top of the drying component 2 through a support frame.

[0058] Based on this, under the above structure, the drying plate 22 should be arranged below the airflow drying cylinder 23 to avoid interference during bidirectional drying.

[0059] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0060] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
