Description

Technical Field

[0001] The utility model belongs to the technical field of sizing equipment, in particular to an adjustable sizing device for corrugated cardboard production with environmental protection. Background Technique

[0002] Corrugated cardboard, also known as corrugated board, is made by bonding at least one layer of corrugated paper and one layer of linerboard. It has good elasticity and extensibility and is mainly used for manufacturing cartons, the sandwich of cartons, and other packaging materials for fragile goods. It is mainly made of native grass pulp and waste paper through beating to make a raw board similar to yellow cardboard, and then mechanically processed into a corrugated shape, and then adhesively bonded with linerboard on its surface with adhesives such as sodium silicate.

[0003] During the production process of corrugated cardboard, glue needs to be applied on the upper part and the glue needs to be scraped flat to facilitate subsequent lamination with other cardboard. For different types of corrugated cardboard, different thicknesses of glue layers need to be applied during the production process. However, the thickness of the glue applied by the existing corrugated cardboard sizing equipment cannot be adjusted, and the height of the scraper needs to be readjusted, which affects the production efficiency. Based on this, we designed a sizing device that can automatically apply glue to corrugated cardboard and can adjust the coating thickness to improve the efficiency of glue application. Content of the Utility Model

[0004] In view of the technical problems existing in the background technique, the utility model provides an adjustable sizing device for corrugated cardboard production with environmental protection, which can automatically apply glue, and automatically smear and scrape flat, effectively improving the efficiency of glue application.

Detailed implementation manners

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model.

[0028] Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the present utility model that is required to be protected, but merely represents selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0029] Such as Figures 1-6As shown in the figure, an adjustable glue scraping device for the production of environmentally friendly corrugated cardboard includes a fixed base 1, a connection groove 2, a blanking mechanism 4 and a scraping mechanism 5. A connection groove 2 is provided on the upper part of the fixed base 1, and a blanking mechanism 4 and a scraping mechanism 5 are respectively arranged inside the connection groove 2. The blanking mechanism 4 includes a blanking groove 401, a first driving motor 403, a second driving motor 407, a disturbance frame 408 and a blanking roller 409. The blanking groove 401 is a rectangular cavity structure. A disturbance frame 408 is arranged inside the blanking groove 401, and one end of the disturbance frame 408 is connected to the first driving motor through a first synchronous belt 405. The blanking roller 409 is arranged at the discharge port of the blanking groove 401, and the blanking groove 401 is connected to the second driving motor 407 through a connecting piece. The scraping mechanism 5 includes a driving box 501, a screw rod 504, a scraping plate 506 and a sensor 508. The scraping plate 506 is connected to the screw rod 504 through a connecting plate 505, and the screw rod 504 is connected to the driving box 501.

[0030] It should be noted that the glue coating will be stirred into a glue state before use and then imported onto the corrugated cardboard, and then scraped flat by a scraper. The existing scraping equipment generally applies glue first and then uses a scraper for scraping and leveling. Although the scraping thickness can be adjusted by replacing the scraper, the efficiency is not high. Therefore, we designed a device that can automatically feed and automatically scrape to improve various efficiencies.

[0031] It should be further noted that for the convenience of blanking, we set a blanking groove 401 inside the connection groove 2, and a blanking roller 409 is arranged at the discharge port of the blanking groove 401. Several rectangular openings 410 are arranged on the upper part of the blanking roller 409. Under the rotation of the blanking roller 409, the glue inside is exported, and it falls to the ground under the action of the gravity of the glue itself to achieve automatic blanking, and cooperate with the subsequent scraping mechanism 5 to scrape the glue flat and evenly apply it on the corrugated cardboard.

[0032] It should be noted again that the function of the scraping mechanism 5 is to scrape and level the dropped glue. In the existing scraping equipment, the scraping plate 506 cannot be adjusted, which is relatively inconvenient to use. Therefore, in order to be able to adjust the scraping process and facilitate the adjustment of the coating thickness, we designed an automatically adjustable scraping mechanism. The scraping plate 506 can be lifted and lowered under the rotation of the screw rod 504, thereby adjusting the distance from the ground surface and controlling the distance.

[0033] Such as Figure 1 、 Figure 4 and Figure 5As shown, the first driving motor 403 is arranged on the supporting platform of the blanking chute 401, and the first synchronous pulley 404 on the output shaft of the first driving motor 403 is connected to the second synchronous pulley 406 on the disturbing frame 408 through the first synchronous belt 405; a feed inlet 402 is arranged at the upper part of the blanking chute 401; a plurality of rectangular openings 410 are arranged at the upper part of the blanking roller 409.

[0034] It should be noted that the glue solution is prone to condensation inside the blanking chute 401. In order to prevent condensation during blanking, a disturbing frame 408 is arranged inside the chamber of the blanking chute 401, which can be driven by the first driving motor 403 to stir the glue solution inside to keep it in a fluid state, facilitating blanking.

[0035] As Figure 3 、 Figure 6 and Figure 8 shown, the screw rod 504 is connected to the inside of the blanking chute 401 through a coupling, and the upper part of the screw rod 504 penetrates into the chamber of the driving box 501. A third synchronous pulley 509 is arranged on the screw rod 504, and the third synchronous pulley 509 is connected to another synchronous pulley through the second synchronous belt 510; a sealing cover 502 is arranged at the upper part of the driving box 501, and a fourth driving motor 503 is arranged at the upper part of the sealing cover 502. The fourth driving motor 503 is connected to the screw rod 504 through a coupling; the scraping plate 506 is arranged on the connecting plate 505, and the connecting plate 505 is connected to the screw rod 504 through the screw holes 507 at both ends; a plurality of sensors 508 are arranged on the connecting plate 505.

[0036] It should be noted that the scraping plate 506 is arranged on the connecting plate 505. By driving the connecting plate 505 to lift and lower, the scraping plate 506 is driven to lift and lower. Moreover, for convenient use, the scraping plate 506 can be made of flexible rubber sheet.

[0037] It should be further noted that in order to control the lifting distance of the scraping plate 506, a plurality of sensors 508 are arranged on the connecting plate 505 to sense the distance from the corrugated paper. The entire screw rod 504 can also be replaced by a lead screw, and the lifting distance of the entire connecting plate 505 is controlled by driving the lead screw through a servo motor, which is convenient for the operator to control.

[0038] As Figure 1 and Figure 7 shown, a plurality of rotating groups 3 are arranged at the bottom of the fixed base 1, and the rotating shafts 8 on the rotating groups 3 are connected to the third driving motor through the pulley 9 and the transmission belt 7. A protective net 6 is arranged at the upper part of the third driving motor; the rotating group 3 includes a connecting bracket 301, a first runner 302 and a second runner 303, and the second runner 303 is connected to the rotating shaft 8 through a coupling.

[0039] It should be noted that in order to achieve automatic gluing, multiple rotating groups 3 are provided at the bottom of the entire device, and automatic walking is achieved under the drive of the third drive motor.

[0040] It should be further noted that two groups of rotating wheels are provided on the upper part of the connecting bracket 301 to facilitate smooth walking on the ground and complete the gluing work during the walking process.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
