Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The directional terms appearing in this utility model are for the purpose of better describing the characteristics of the features and the relationships between them. It should be understood that when the placement direction of this utility model changes, the direction of the characteristics of the features and the relationships between them also changes accordingly. Therefore, directional terms do not constitute an absolute limitation on the characteristics of the features and the relationships between them in space, but only a relative limitation.

[0030] like Figures 1 to 12 As shown, this utility model provides a corrugated paper sizing and scraping device, including a frame 1, on which a sizing mechanism is provided. The sizing mechanism includes a sizing component 2, a primary scraping component 3, and a secondary scraping component 4. The sizing component 2 includes a sizing tank 20, a coating roller 21, a roller drive component 22, and a lifting drive component 23. The lifting drive component 23 is installed on the frame 1 and is used to drive the sizing tank 20 to rise or fall. The coating roller 21 and the roller drive component 22 are installed on the sizing tank 20. The roller drive component 22 is used to drive the coating roller 21 to rotate.

[0031] The primary scraping assembly 3 is used to scrape off excess slurry on the coating roller 21. It includes a slide table 30, a sliding drive 31, and a clamp 32. The sliding drive 31 is mounted on the frame 1 and is used to drive the slide table 30 closer to or further away from the coating roller 21. The slide table 30 is provided with a clamp 32, which is used to hold the primary scraper 35.

[0032] The secondary doctor blade assembly 4 is used to scrape the pulp on the plain paper. It includes a pressure drive 40, a support plate 41, a mounting plate 42, and a secondary doctor blade 43. The pressure drive 40 is mounted on the frame 1 and is used to drive the support plate 41 to rise or fall. The mounting plate 42 is mounted on the frame 1 and is located directly below the support plate 41. The secondary doctor blade 43 is mounted on the mounting plate 42.

[0033] With the above design, during the sizing process, the coating roller 21 can pick up the sizing material from the sizing tank 20, and the primary doctor blade 35 will scrape off the excess sizing material on the coating roller 21 to prevent excessive sizing material from adhering to the base paper. The base paper with sizing material will continue to pass through the secondary doctor blade assembly 4, and the side of the base paper with sizing material will press against the support plate 41. With the help of the secondary doctor blade 43, the excess sizing material adhering to the base paper can be scraped off, ensuring that the sizing material on the base paper is sufficiently uniform.

[0034] The sliding drive 31 controls the sliding table 30 to move the clamp 32 closer to or further away from the coating roller 21, thereby controlling the distance between the primary doctor blade 35 and the coating roller 21, and thus controlling the thickness of the slurry on the coating roller 21. The mounting plate 42 and the secondary doctor blade 43 are fixed on the frame 1. The downward drive 40 drives the downward pressing block to move downward, thereby controlling the distance between the downward pressing block and the secondary doctor blade 43. The base paper passing under the support plate 41 is pressed close to the secondary doctor blade 43 by the support plate 41. The secondary doctor blade 43 can make the slurry on the base paper flat and uniform, avoiding excessive slurry accumulation on the base paper and affecting the adhesion effect. The slurry scraped off by both the primary doctor blade 35 and the secondary doctor blade 43 will fall back into the slurry pool 20, reducing slurry waste.

[0035] In this embodiment, a circulation assembly 5 is also provided on the frame 1. The circulation assembly 5 includes a material tank 50, a circulation pump 51, a discharge outlet 52, and a return outlet 53. The material tank 50 is installed on the frame 1, the circulation pump 51 is installed on the material tank 50, and the discharge outlet 52 and the return outlet 53 are both installed in the slurry tank 20. The discharge outlet 52 is located at the end of the slurry tank 20 near the coating roller 21 and is connected to the circulation pump 51 through a hose 54. The slurry in the material tank 50 can be pumped by the circulation pump 51 and transported to the slurry tank 20 through the discharge outlet 52. Excess slurry in the slurry tank 20 will flow back to the material tank 50 under the guidance of the return outlet 53.

[0036] Through the above design scheme, the circulation component 5 can keep the slurry in a flowing state at all times, avoiding the sedimentation of the slurry. At the same time, a heating device is also provided in the material tank 50 to heat the slurry in the material tank 50. The heated slurry is pumped by the circulation pump 51 through the hose 54 to the discharge outlet 52, and then sprayed onto the coating roller 21 through the discharge outlet 52. Some slurry will stick to the coating roller 21, while the excess slurry will drip into the slurry pool 20. The slurry in the slurry pool 20 will flow to the return material outlet 53. Under the guidance of the return material outlet 53, the slurry will return to the material tank 50 to continue to participate in the circulation.

[0037] In this embodiment, support frames are provided on both sides of the slurry tank 20, and support rollers are provided on the support frames. The paint roller 21 can fall stably onto the support rollers under the action of gravity, and the support rollers can reduce the friction between the paint roller 21 and the support frame. In this embodiment, the roller drive 22 is connected to the paint roller 21 via a belt.

[0038] In this embodiment, a transmission assembly 6 is provided on the frame 1. The transmission assembly 6 includes an active roller 60, an auxiliary roller 61, a tension roller 62, and a main roller 63. The raw paper passes through the active roller 60, the tension roller 62, the auxiliary roller 61, and the main roller 63 in sequence. The main roller 63 is used to coat the raw paper with slurry in conjunction with the coating roller 21. The active roller 60, the auxiliary roller 61, the tension roller 62, and the main roller 63 are all mounted on the frame 1.

[0039] In this embodiment, the frame 1 is provided with two sets of active rollers 60, two sets of auxiliary rollers 61, and one set of main rollers 63. The two sets of active rollers 61 are close together to draw the raw paper into the frame 1. One set of auxiliary rollers 61 is located near the active rollers 63, and the other set is located near the secondary scraping assembly 4. The raw paper passes through the active rollers 60, around the tension rollers 62, and then through the two sets of auxiliary rollers 61 before reaching the main rollers 63. The main rollers 63 can press against the coating rollers 21, pressing the raw paper onto the coating rollers 21. When it is necessary to adjust the distance between the main rollers 63 and the coating rollers 21, the lifting drive 23 can drive the pulp tank 20 to rise or fall, and the coating rollers 21 on the pulp tank 20 will rise and fall with the rise and fall of the pulp tank 20.

[0040] In this embodiment, tensioning components 64 are installed at both ends of the tensioning roller 62. The tensioning components 64 include a slide rod 643, a tensioning elastic element 641, a baffle 642, and an end frame 640. The slide rod 643 is installed on the frame 1 through the end frame 640. The tensioning elastic element 641 and the baffle 642 are both sleeved on the slide rod 643. Slide grooves 620 are provided at both ends of the tensioning roller 62, and the slide grooves 620 can slide on the slide rod 643. One end of the tensioning elastic element 641 abuts against the end frame 640, and the other end abuts against the baffle 642, and the baffle 642 abuts against the tensioning roller 62.

[0041] Through the above design scheme, the tensioning component 64 is used to adjust the tension of the base paper, so as to avoid the base paper being too tight or too loose, which would affect the coating effect.

[0042] In this embodiment, the fixture 32 includes a connecting seat 33, a hinge seat 34, and a pressure plate 37. The connecting seat 33 is detachably connected to the slide table 30. The hinge seat 34 is connected to the connecting seat 33 through a locking rod 36. The locking rod 36 is used to lock the hinge seat 34 and the connecting seat 33 together. The pressure plate 37 is used to press the primary scraper 35 onto the hinge seat 34.

[0043] With the above design, when the locking rod 36 is loosened, the hinge seat 34 can rotate around the connecting seat 33 with the locking rod 36 as the axis. When it rotates to a suitable angle, tightening the locking rod 36 will install the hinge seat 34 on the connecting seat 33.

[0044] In this embodiment, the frame 1 is provided with a hot air chamber 7 near the secondary scraper assembly 4, and the hot air chamber 7 can blow out hot air.

[0045] With the above design scheme, the hot air chamber 7 is equipped with a fan and heating wire. The airflow blown out by the fan is heated by the heating wire and then blown onto the base paper coated with pulp, so as to prevent the base paper from being soaked by pulp.

[0046] In this embodiment, a plurality of displacement windows 10 are provided on the rack 1.

[0047] The replacement window 10 is located near the corresponding primary scraper 35, secondary scraper 43 and paint roller 21, making it convenient for users to replace the primary scraper 35, secondary scraper 43 or paint roller 21.

[0048] In this embodiment, the lifting drive 23, the sliding drive 31 and the material roller drive 22 can be motors, and the pressing drive 40 can be a cylinder or a hydraulic cylinder.

[0049] The corrugated paper sizing and scraping device provided by this utility model, compared with the prior art, when sizing the base paper, the sizing material flowing out from the discharge outlet 52 will adhere to the coating roller 21. The primary scraper 35 is used to scrape off the excess sizing material on the coating roller 21. The remaining sizing material will be transferred to the base paper with the assistance of the main roller 63. When the base paper with sizing material adheres to the secondary scraping assembly 4, it will be scraped flat by the secondary scraper 43 to ensure that the sizing material on the base paper is more uniform.

[0050] Where there is no conflict, the above embodiments and features can be combined with each other.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
