In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Figures 1-3 The present invention relates to a scraper adjustment mechanism for carton production, comprising a bracket 10, a power component 20, a scraper assembly 30, and an angle adjustment component 40.

[0023] In this embodiment:

[0024] The power assembly 20 includes a motor 21, a lead screw 22, a lead screw nut 23, a motor mounting base 24, and two guide rails 25.

[0025] The motor mounting base 24 is mounted on the bracket 10. The motor 21 is mounted on the motor mounting base 24 and is connected to the lead screw 22 for transmission. The lead screw nut 23 is sleeved on the lead screw 22. The motor 21 drives the lead screw 22 to rotate and drives the lead screw nut 23 to move along the axial direction of the lead screw 22. In this embodiment, the motor 21 is a stepper motor 21. The motor 21 is electrically connected to an external controller, which can precisely control the rotation angle of the motor 21, thereby achieving precise adjustment of the vertical position of the scraper blade body 33.

[0026] Two guide rails 25 are mounted on the bracket 10 in parallel relative to each other, and the length direction of the guide rails 25 is parallel to the axial direction of the lead screw 22.

[0027] The glue scraper assembly 30 includes a connecting seat 31, a glue scraper body 33, a glue scraper mounting seat 34, a gasket 35, and two sliders 32.

[0028] The connecting seat 31 is fixedly connected to the lead screw nut 23.

[0029] The glue scraper mounting base 34 is fixedly connected to the connecting base 31. The glue scraper body 33 is mounted on the glue scraper mounting base 34, and the blade end of the glue scraper body 33 is inclined.

[0030] Each slider 32 is slidably mounted on a guide rail 25, and the slider 32 is fixedly connected to the connecting seat 31 to ensure that the scraper assembly 30 moves smoothly.

[0031] The shim 35 is placed between the scraper body 33 and the scraper mounting base 34. By replacing the shim 35 with different thicknesses, the blade height of the scraper body 33 can be finely adjusted. At the same time, it facilitates the replacement and maintenance of the scraper body 33 and reduces the equipment operating cost.

[0032] The angle adjustment assembly 40 includes two side plates 41, two pins 42, and two locking elements 43.

[0033] Two side plates 41 are mounted on the connecting seat 31 and located on both sides of the scraper mounting seat 34. The side plates 41 are provided with arc-shaped holes 411. The connection point between the scraper mounting seat 34 and the connecting seat 31 coincides with the center of the arc-shaped hole 411, ensuring that the blade tip of the scraper body 33 remains stable during angle adjustment and preventing scraping position shift during angle adjustment. In this embodiment, the arc of the arc-shaped hole 411 is in the range of 0° to 30°.

[0034] A pin 42 passes through an arc-shaped hole 411. The glue scraper mounting base 34 is hinged to the side plate 41 via the pin 42, allowing it to rotate around the pin 42 within the arc-shaped hole 411. This enables flexible adjustment of the angle of the glue scraper body 33, adapting to the glue scraping requirements of different sized cartons and different types of glue. In this embodiment, the width of the arc-shaped hole 411 matches the diameter of the pin 42.

[0035] Two locking components 43 are respectively installed on the two side plates 41. The locking components 43 include bolts 431, nuts 432, and knobs 433.

[0036] The screw end of bolt 431 passes through side plate 41 and is threadedly connected to the side of scraper mounting seat 34. Nut 432 is sleeved on the screw of bolt 431 and abuts against the outer wall of side plate 41.

[0037] The head of bolt 431 forms a knob 433, which is located outside the side plate 41. By tightening the knob 433, the nut 432 is tightly abutted against the side plate 41, and the bolt 431 is tightly locked to the glue scraper mounting seat 34, thereby locking the rotation angle of the glue scraper mounting seat 34 and the glue scraper body 33. This effectively prevents angle deviation caused by vibration during operation, ensures consistent glue application, and improves the bonding quality of the carton. In this embodiment, the outer peripheral wall of the knob 433 is provided with anti-slip texture to increase the friction between the hand and the knob 433, making it easy for the operator to manually turn the knob 433 to lock or unlock the angle.

[0038] The working process for this application is as follows:

[0039] According to the thickness of the cardboard, the external controller sends a control signal to the motor 21. The motor 21 drives the lead screw 22 to rotate, and the lead screw nut 23 moves vertically along the lead screw 22, which in turn drives the connecting seat 31, the scraper mounting seat 34 and the scraper body 33 to move up and down until the blade of the scraper body 33 reaches the preset scraping position, and the motor 21 stops working.

[0040] Loosen the knob 433 of the threaded locking part 43 to separate the nut 432 from the side plate 41 and loosen the threaded connection between the bolt 431 and the scraper mounting base 34; push the scraper mounting base 34 to rotate it around the pin 42 within the range of the arc hole 411, and adjust the contact angle between the blade end of the scraper body 33 and the cardboard surface until the angle is appropriate; tighten the knob 433 to make the nut 432 and the side plate 41 fit tightly together and the bolt 431 and the scraper mounting base 34 lock tightly together, thus completing the angle locking;

[0041] The cardboard production line is started, the cardboard moves along the preset path, and the blade of the glue scraper body 33 applies glue evenly to the surface of the cardboard.

[0042] This application features a simple structure and convenient operation, enabling precise adjustment and secure locking of the glue scraper's position and angle. It effectively improves the uniformity and stability of glue application during carton production, adapts to the needs of automated production lines, and has high practical value.

[0043] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
