[0033] Please refer to Figures 1 to 4 , in order to better understand the glue coating tank device 10 for water transfer printing paper production of the present application, the following further explanatory description is made on the glue coating tank device 10 for water transfer printing paper production:

[0034] The sizing material tank device 10 for water transfer paper production in one embodiment includes a coating sizing roller 100, a sizing material tank body 200, and a filter plate 300. The coating sizing roller 100 is rotatably connected to the frame 400 of the coater, and the coating sizing roller 100 is also connected to the transmission device of the coater; the sizing material tank body 200 is provided with a sizing liquid storage tank 201, the sizing material tank body 200 includes a partition plate 210, the partition plate 210 is provided with an overflow notch 2101, the partition plate 210 is located in the sizing liquid storage tank 201 to divide the sizing liquid storage tank 201 into a liquid inlet buffer tank 201a and a return flow tank 201b at intervals, the liquid inlet end of the liquid inlet buffer tank 201a is communicated with the liquid outlet end of the liquid supply system, and the liquid outlet end of the return flow tank 201b is communicated with the liquid inlet end of the sizing liquid recovery system; the sizing material tank body 200 is inclined and arranged between the frames 400 of the coater; the filter plate 300 is arranged at the overflow notch 2101 and is inserted into the partition plate 210; the liquid supply system is used to supply sizing material liquid to the liquid inlet buffer tank 201a, and the liquid inlet buffer tank 201a is communicated with the return flow tank 201b through the filter holes of the filter plate 300.

[0035] In this embodiment, the sizing material liquid is continuously supplied to the liquid inlet buffer tank 201a through the liquid supply system, so that the adhesive outer surface of part of the coating sizing roller 100 can always be located below the liquid level of the sizing material liquid in the liquid inlet buffer tank 201a. The excess sizing material liquid in the liquid inlet buffer tank 201a can overflow into the return flow tank 201b through the filter holes of the filter plate 300 in time, so as to keep the sizing material liquid in the liquid inlet buffer tank 201a always in a molten flowing state. The sizing material tank device of the utility model can enable the sizing material liquid to be transferred and adhered to the surface of the base paper in time and quickly through the coating sizing roller 100 under the flowing state with good activity, temperature and viscosity, so as to effectively ensure the surface sizing quality of the base paper; further, the filter plate 300 is arranged at the overflow notch 2101 to realize the filtration and diversion of the sizing material liquid overflowing into the return flow tank 201b, so as to effectively avoid the problem that the liquid outlet end of the return flow tank 201b is blocked due to the deposition and caking of the sizing material liquid or other filter residues.

[0036] As Figure 3 shown, in one embodiment, the sizing material tank body 200 is inclined at a preset inclination angle, and the range of the preset inclination angle is between 30 degrees and 60 degrees.

[0037] It can be understood that in the present embodiment, the preset inclination angle of the rubber tank body 200 can be adjusted so that the rubber liquid in the liquid inlet buffer tank 201a has more or less gravitational potential energy, thereby adjusting the self-overflow rate of the rubber liquid in the liquid inlet buffer tank 201a; in other embodiments, the production personnel can also adjust the rate at which the rubber liquid is continuously supplied to the liquid inlet buffer tank 201a by regulating the liquid supply system to adjust the self-overflow rate of the rubber liquid in the liquid inlet buffer tank 201a.

[0038] It should be noted that if Figure 3 The angle indicated by X is a preset tilt angle, that is, the angle range of X is between 30 degrees and 60 degrees.

[0039] like Figure 1 and Figure 3 As shown, in one embodiment, a first inserting portion 310 is formed at one end of the filter plate 300, a second inserting portion 320 is formed at the other end of the filter plate 300, and a middle inserting portion 330 is formed at the middle of the filter plate 300;

[0040] The periphery of the overflow notch 2101 is respectively provided with a first slot 2102, a second slot 2103 and an intermediate positioning slot 2104; the first slot 2102, the second slot 2103 and the intermediate positioning slot 2104 are all connected to the overflow notch 2101; the first inserting portion 310 is arranged in the first slot 2102, the second inserting portion 320 is arranged in the second slot 2103, and the intermediate inserting portion 330 is arranged in the intermediate positioning slot 2104, so that the filter plate 300 is plugged with the partition plate 210. In one embodiment, the filter plate 300 is an integrally formed structure. In one embodiment, the filter plate 300 is provided with a handle portion (not shown), and the handle portion (not shown) is arranged at one end away from the intermediate inserting portion 330.

[0041] It can be understood that production personnel can remove or install the filter plate 300 from the partition 210 by holding the handle (not shown) to clean the filter holes on the filter plate 300 to ensure that the filter plate 300 continues to filter efficiently, thereby avoiding the problem of blockage of the liquid outlet end of the reflux tank 201b caused by long-term accumulation of filter residue.

[0042] It should be noted that, in the present embodiment, the number of filter plates 300 is three, and the number of corresponding overflow notches 2101 is also three; in other embodiments, the user can set the number of filter plates 300 and overflow notches 2101 according to actual needs.

[0043] like Figures 1 to 4As shown, in one embodiment, the sizing trough device 10 for water transfer paper production further includes a plurality of liquid supply pipes 500. One ends of the plurality of liquid supply pipes 500 are all connected to the bottom of the liquid inlet buffer tank 201a, and the other ends of the plurality of liquid supply pipes 500 are all connected to the liquid outlet end of the liquid supply system. In one embodiment, the plurality of liquid supply pipes 500 are arranged in linear spaced distribution. In one embodiment, the sizing trough device 10 for water transfer paper production further includes a return pipe 600. One end of the return pipe 600 is connected to the bottom of the return tank 201b, and the other end of the return pipe 600 is connected to the liquid inlet end of the glue liquid recovery system; a drainage conical surface 610 is formed around the circumference of the pipe orifice at one end of the return pipe 600.

[0044] It can be understood that in this embodiment, the plurality of liquid supply pipes 500 are arranged in linear spaced distribution, and one ends of the plurality of liquid supply pipes 500 are all connected to the bottom of the liquid inlet buffer tank 201a, so that the liquid outlet end of the liquid supply system supplies the sizing liquid to the liquid inlet buffer tank 201a more evenly, sufficiently and stably. Thus, there is no need to worry about the problem that the sizing liquid in the liquid inlet buffer tank 201a is insufficiently supplied, resulting in a sharp drop in the liquid level of the sizing liquid.

[0045] Specifically, one ends of the plurality of liquid supply pipes 500 are all connected to the bottom of the liquid inlet buffer tank 201a, so that the sizing liquid gushing out from one end of the liquid supply pipes 500 continuously disturbs and pushes the sizing liquid in the liquid inlet buffer tank 201a. Furthermore, the sizing liquid in the liquid inlet buffer tank 201a cannot have a static deposition phenomenon, effectively avoiding the problem of the sizing liquid depositing and caking; more specifically, combined with the function of the filter plate 300 for filtering residues, the problem of blockage of the return pipe 600 is effectively avoided. At the same time, the setting of the drainage conical surface 610 can better drain the sizing liquid to the return pipe 600.

[0046] As Figure 1 As shown, in one embodiment, a first handle member 700 and a second handle member 800 are provided on the outer side of the sizing tank body 200; both the first handle member 700 and the second handle member 800 are welded to the sizing tank body 200.

[0047] It can be understood that production personnel can adjust the preset inclination angle of the sizing tank body 200 by respectively holding the first handle member 700 and the second handle member 800.

[0048] This application also provides a coating machine, including the sizing trough device 10 for water transfer paper production described in any one of the above embodiments.

[0049] In this embodiment, the feeding system continuously supplies the sizing liquid into the feeding buffer tank, so that the adhesive outer surface of part of the coating rubber roller can always be located below the liquid level of the sizing liquid in the feeding buffer tank. The excess sizing liquid in the feeding buffer tank can overflow into the reflux tank through the filter holes of the filter plate in time, so as to keep the sizing liquid in the feeding buffer tank in a molten flowing state all the time. The coater of the utility model can enable the sizing liquid to be transferred and adhered to the surface of the base paper through the coating rubber roller in time and quickly under the flowing state with good activity, temperature and viscosity, so as to effectively ensure the surface sizing quality of the base paper; Further, the filter plate is arranged at the overflow notch to realize the filtration and diversion of the sizing liquid overflowing into the reflux tank, so as to effectively avoid the problem that the liquid outlet end of the reflux tank is blocked due to the deposition and caking of the sizing liquid or other filter residues.

[0050] Compared with the prior art, the utility model has at least the following advantages:

[0051] The feeding system continuously supplies the sizing liquid into the feeding buffer tank, so that the adhesive outer surface of part of the coating rubber roller can always be located below the liquid level of the sizing liquid in the feeding buffer tank. The excess sizing liquid in the feeding buffer tank can overflow into the reflux tank through the filter holes of the filter plate in time, so as to keep the sizing liquid in the feeding buffer tank in a molten flowing state all the time.
