Description

Technical Field

[0001] The utility model relates to the technical field of sizing machines, in particular to a temperature controllable film transfer sizing machine. Background Technique

[0002] Sizing machines are divided into two forms: horizontal and inclined, with pneumatic pressure. The purpose of surface sizing is usually to prevent liquid penetration, obtain better surface properties and improve the physical properties of paper (such as surface strength and internal bonding force). It is an effective means to improve the properties of base paper. Through the surface sizing machine, the emulsified sizing liquid is continuously, evenly and stably coated on the surface of the formed paper. After a series of physical actions such as infiltration and penetration extrusion, a very thin waterproof layer is formed on the surface of the formed paper, greatly improving the water absorption of the paper. At the same time, under the action of the sizing liquid, the bonding strength between fibers and the tightness of the paper are improved, thereby improving technical indicators such as the transverse ring crush index and the longitudinal breaking length of the paper.

[0003] At present, the existing film transfer sizing machine uses the sizing liquid in the sizing tank to perform sizing treatment on the paper. However, the sizing liquid used for sizing is relatively sensitive to temperature changes. Too high or too low temperature is not conducive to the surface sizing process of the paper. At the same time, the sizing tank is used for feeding and no device for multiple uniform coating is installed, so the uniformity during sizing is not good enough, which is not conducive to improving the sizing uniformity of the film transfer sizing machine for the paper, resulting in a poor sizing effect and affecting the quality of the paper.

[0004] Therefore, in view of the above problems, we propose a temperature controllable film transfer sizing machine to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a temperature controllable film transfer sizing machine that can effectively heat the sizing liquid, accurately control the temperature, improve the sizing uniformity, and the sizing effect and quality, so as to solve the problems raised in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A temperature controllable film transfer sizing machine, which includes a base, a film transfer sizing box is fixed on the upper end of the base, fixing plates are symmetrically arranged on both sides of the upper end of the film transfer sizing box, a first rubber tube is arranged between the fixing plates, a second rubber tube is arranged in the middle of the lower end of the first rubber tube, a glue spraying plate is arranged at the lower end of the second rubber tube, sizing rollers are symmetrically arranged up and down at the lower end of the glue spraying plate, a material tank is arranged at the lower end of the sizing rollers, a constant temperature heating plate is arranged at the inner bottom of the material tank, a conical filter screen is arranged in the middle of the constant temperature heating plate, a hollow tube is arranged on the conical filter screen, the lower end of the hollow tube is connected to a second motor, the hollow tube further includes stirring rods arranged on the outside and a third rubber tube arranged inside, the other end of the third rubber tube is connected to a rubber pump inside one side of the fixing plate, a temperature sensor is further arranged on one side of the upper end of the inner wall of the material tank, the temperature sensor is connected to a control board by a wire harness, and the control board is connected to a control panel by a wire harness.

[0010] Preferably, scraping plates are symmetrically arranged on both sides of the sizing rollers, a limit stud is arranged in the middle of the upper end of the scraping plate, and scraping sheets are arranged on the inner side of the scraping plate at the lower end of the limit stud.

[0011] Preferably, the scraping plate includes double-headed threaded rods arranged at both ends, and a rotating part arranged at the upper end and a threaded block arranged in the middle are included on the double-headed threaded rods.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] The utility model is provided with a control panel on the surface of a film transfer sizing box, enabling the freely adjustment and setting of the temperature suitable for glue heating through the buttons and knobs on the control panel. The glue in the trough is heated by a constant-temperature heating plate at the bottom end inside the trough, effectively achieving the constant-temperature heating of the glue. The hollow tube is rotated by a second motor, and the glue is stirred through a stirring rod, enabling the temperature on the surface and inside of the glue to approach more quickly, thereby achieving more uniform heating. The stable collection is carried out through a temperature sensor, which is conducive to ensuring accurate temperature control and constant temperature. At the same time, heating automatically pauses when the set temperature is exceeded, and the glue temperature is prevented from being too high or too low, resulting in a poor sizing effect and affecting the paper quality.

The glue is introduced into the first rubber tube through a rubber pump, and flows into the inside of the spray sizing plate through a second rubber tube arranged at the lower end of the first rubber tube. Through an air pump, the spray nozzles at the lower end of the spray sizing plate spray the glue onto the sizing roller, and then the scraping film at the end of the scraping plate contacts the glue on the surface of the sizing roller, thereby scraping the glue evenly, enabling the material to be sized evenly, and being conducive to improving the sizing uniformity of the film transfer sizing machine for paper.
