Description

Technical Field

[0001] This utility model relates to the field of packaging adhesive coating technology, and in particular to an adhesive coating device. Background Technology

[0002] With the advancement of industrial technology, automated product packaging machines are now widely available. These machines apply adhesive to the label paper on small boxes via a glue cylinder, then shape and fix the product through various folding processes before drying. However, in existing packaging machines, the glue-applying roller carries some adhesive out during operation. The amount of adhesive on the glue-applying roller is adjusted by controlling the distance between the scraper and the roller, but the scraper material is easily worn, making it difficult to maintain a stable amount of adhesive. Furthermore, manual replacement of the scraper is required, and controlling the installation precision between the scraper and the roller during replacement is challenging. This can lead to poor packaging results and low yield rates when the product is reused.

[0003] Therefore, there is an urgent need for a packaging device to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a packaging device that can accurately control the amount of adhesive scraping, improve the adhesive scraping effect, increase automation precision, and reduce manual intervention.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] An adhesive application apparatus, comprising:

[0007] A glue box, set on a support surface, contains adhesive liquid;

[0008] An adhesive roller is rotatably connected to the inside of the adhesive box, and at least part of its outer circumference is immersed in the adhesive liquid, so that the adhesive liquid can adhere to the roller when it rotates.

[0009] A scraping mechanism is disposed on one side of the rotation direction of the glue-applying roller. The scraping mechanism includes a pressure roller and two side scraping rollers. Two side scraping rollers are sleeved on the outer periphery of the pressure roller, and the two side scraping rollers are spaced apart to form a scraping space. When the glue-applying roller rotates, it can pass through the scraping space, and the side scraping rollers can scrape off the glue on both sides of the glue-applying roller along the thickness direction. After passing through the scraping space, the glue-applying roller can coat the outer periphery of the glue onto the label surface.

[0010] Preferably, the glue scraping mechanism further includes a mounting plate and a movable plate. The mounting plate is disposed on the glue tank, and the pressure roller is disposed on the movable plate. The movable plate is hinged to the mounting plate, and the rotation of the movable plate can adjust the distance between the pressure roller and the glue roller.

[0011] Preferably, the movable plate is provided with a clearance groove, a connecting shaft is provided in the clearance groove, and the pressure roller is provided on the outer periphery of the connecting shaft.

[0012] Preferably, the adhesive scraping mechanism further includes a first adjusting component, which, when rotated, allows the movable plate to rotate about the hinge position.

[0013] Preferably, the first adjustment component includes a first knob and a first elastic element. The first knob passes through the movable plate and the mounting plate in sequence and is threadedly connected to the mounting plate. The first elastic element is sleeved on the outer periphery of the first knob and is located between the knob cap and the movable plate. An abutment portion is provided at one end of the first knob that passes through the movable plate. When the first knob is rotated clockwise, the first elastic element is compressed, causing the movable plate to rotate toward the mounting plate. When the first knob is rotated counterclockwise, the abutment portion abuts against the bottom end of the movable plate, causing the movable plate to rotate away from the mounting plate.

[0014] Preferably, the adhesive scraping mechanism further includes a second adjustment component, which can be rotated to adjust the distance between the two side adhesive scraping wheels.

[0015] Preferably, the second adjustment component includes a second knob and a second elastic element. The second knob is threaded to the connecting shaft, and one end of the second elastic element is connected to the second knob, while the other end is connected to the side scraping roller. When the second knob is rotated, the second elastic element can drive the side scraping roller to move.

[0016] Preferably, each of the side scraping rollers is provided with a set of the second adjustment components.

[0017] Preferably, multiple glue-applying rollers are spaced apart, and the glue-scraping mechanism is arranged corresponding to the glue-applying rollers.

[0018] Preferably, the adhesive applicator further includes a plurality of label pressure rollers, which are respectively disposed above the plurality of adhesive rollers to fix the label when adhesive is applied to the adhesive rollers.

[0019] The beneficial effects of this utility model are:

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0033] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between 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.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0036] This embodiment provides an adhesive application device, such as... Figure 1As shown, the device includes a glue tank 10, an applicator roller 20, and a scraping mechanism 30. The glue tank 10 is disposed on a support surface and contains glue 40. The applicator roller 20 is rotatably connected to the inside of the glue tank 10, and at least part of its outer circumference is immersed in the glue 40 so that the glue 40 adheres to the roller when it rotates. The scraping mechanism 30 is disposed on one side of the rotation direction of the applicator roller 20. The scraping mechanism 30 includes a pressure roller 31 and two side scraping rollers 32. The pressure roller 31 is fitted with two side scraping rollers 32 on its outer circumference, and the two side scraping rollers 32 are spaced apart to form a scraping space 33. When the applicator roller 20 rotates, it can pass through the scraping space 33, and the side scraping rollers 32 can scrape off the glue 40 on both sides of the applicator roller 20 along the thickness direction. After passing through the scraping space 33, the applicator roller 20 can coat the outer circumference of the glue 40 onto the surface of the label 60.

[0037] In this device, as the gluing roller 20 rotates, it passes through the adhesive 40, resulting in adhesive 40 adhering to its outer circumference and both sides along the thickness direction. After passing through the scraping space 33, the side scraping rollers 32 scrape away excess adhesive 40 from both sides (along the thickness direction) of the gluing roller 20. After passing through the scraping space 33, only the outer circumference of the gluing roller 20 is covered with adhesive 40. With continued rotation, the adhesive 40 on the outer circumference can be coated onto the outer surface of the label 60, thus completing the automatic adhesive application process. In this process, by ensuring that the distance between the two side scraping rollers 32 is approximately equal to the thickness of the gluing roller 20, the amount of adhesive scraped can be precisely controlled without causing wear on the side scraping rollers 32, ensuring a good scraping effect. This process is highly automated and avoids the need for manual positioning based on experience, ensuring good positioning accuracy and indirectly improving the coating effect, while also increasing the yield rate of packaging.

[0038] Specifically, such as Figure 1 As shown, the glue scraping mechanism 30 also includes a mounting plate 34 and a movable plate 35. The mounting plate 34 is disposed on the glue tank 10, and the pressure roller 31 is disposed on the movable plate 35. The movable plate 35 is hinged to the mounting plate 34. The rotation function of the movable plate 35 can adjust the distance between the pressure roller 31 and the upper glue roller 20. In this structure, the mounting plate 34 is disposed on the glue tank 10, which can ensure the stability of the glue scraping mechanism 30. The movable plate 35 is hinged to the mounting plate 34, and the pressure roller 31 is disposed on the movable plate 35. Therefore, by rotating the movable plate 35 and adjusting the angle, the distance between the pressure roller 31 and the upper glue roller 20 can be indirectly adjusted, thereby avoiding the upper glue roller 20 from getting stuck due to too small a distance, and also avoiding the upper glue roller from getting stuck or worn due to too large a distance.

[0039] To simplify the overall structure, such as Figure 1As shown, the movable plate 35 is provided with a clearance groove 351, and a connecting shaft 38 is also provided in the clearance groove 351. The pressure roller 31 is located on the outer periphery of the connecting shaft 38. Setting the pressure roller 31 in the clearance groove 351 can effectively prevent it from protruding outward too much, ensuring ease of use; in addition, fixing the pressure roller 31 to the connecting shaft 38 can also effectively improve the ease of installation.

[0040] In addition, such as Figure 1 As shown, the glue-scraping mechanism 30 also includes a first adjustment component 36. Rotating the first adjustment component 36 allows the movable plate 35 to rotate around the hinge position. By setting the first adjustment component 36, the movable plate 35 can be fixed at a specific angle to prevent it from moving, thereby maintaining the distance between the pressure roller 31 and the glue-applying roller 20. When the position needs to be adjusted, the movable plate 35 can be rotated around the hinge position, thereby improving the convenience and flexibility of the rotation of the movable plate 35.

[0041] Specifically, such as Figure 1 As shown, the first adjustment component 36 includes a first knob 361 and a first elastic member 362. The first knob 361 passes through the movable plate 35 and the mounting plate 34 in sequence and is threadedly connected to the mounting plate 34. The first elastic member 362 is sleeved on the outer periphery of the first knob 361 and is located between the knob cap of the first knob 361 and the movable plate 35. An abutment portion is provided at one end of the first knob 361 that passes through the movable plate 35. When the first knob 361 is rotated clockwise, the first elastic member 362 is compressed, causing the movable plate 35 to rotate toward the mounting plate 34. When the first knob 361 is rotated counterclockwise, the abutment portion can abut against the bottom end of the movable plate 35 and drive the movable plate 35 to rotate away from the mounting plate 34. In this structure, since the first knob 361 is threadedly connected to the mounting plate 34, it can rotate clockwise or counterclockwise around its own axis. When rotating clockwise, the first knob 361 moves downward, thus compressing the first elastic element 362 through the knob cap. The elastic force of the first elastic element 362 causes the movable plate 35 to rotate towards the mounting plate 34. When rotating in the opposite direction, the first knob 361 moves upward, and its abutting part abuts against and forms the bottom end of the movable plate 35, thereby driving it to rotate away from the mounting plate 34. The structure is simple and easy to operate, allowing the movable plate 35 to be quickly adjusted to a preset position with high adjustment accuracy, maintaining the distance between the pressure roller 31 and the upper rubber roller 20.

[0042] In addition, such as Figure 1 As shown, the adhesive scraping mechanism 30 also includes a second adjustment component 37. Rotating the second adjustment component 37 can adjust the distance between the two side adhesive scraping rollers 32. The second adjustment component 37 can quickly and accurately adjust the distance between the two side adhesive scraping rollers 32, thereby improving the accuracy of adhesive scraping, ensuring a good adhesive scraping effect, and improving the yield rate of packaging.

[0043] Specifically, such as Figure 1 As shown, the second adjustment component 37 includes a second knob 371 and a second elastic element 372. The second knob 371 is threaded to the connecting shaft 38. One end of the second elastic element 372 is connected to the second knob 371, and the other end is connected to the side scraping roller 32. When the second knob 371 is rotated, the second elastic element 372 can drive the side scraping roller 32 to move. In this structure, rotating the second knob 371 in one direction can compress the second elastic element 372, thereby causing the side scraping roller 32 to move. This allows adjustment of the distance between the two side scraping rollers 32, thus adjusting the size of the scraping space 33 and ensuring good scraping accuracy and effect.

[0044] It should be noted that in this embodiment, both the first elastic element 362 and the second elastic element 372 are springs. Springs have a simple structure, are inexpensive, easy to install and use, and can effectively reduce costs.

[0045] like Figure 1 As shown, each side scraping roller 32 is equipped with a corresponding set of second adjustment components 37. This arrangement allows for individual adjustment of the actual position of a single side scraping roller 32, thereby ensuring good performance.

[0046] To improve adhesive application efficiency, such as Figure 1 As shown, multiple gluing rollers 20 are spaced apart, and a scraping mechanism 30 is correspondingly arranged with each gluing roller 20. This arrangement allows multiple gluing rollers 20 to operate simultaneously, thereby improving gluing efficiency. Furthermore, the corresponding arrangement of the scraping mechanism 30 with the gluing rollers 20 ensures that the glue 40 on both sides of each gluing roller 20 can be scraped off, thus guaranteeing a good gluing effect and improving the yield rate of packaging.

[0047] In addition, such as Figure 1 As shown, the adhesive application device also includes multiple label pressure rollers 50, which are respectively positioned above multiple adhesive rollers 20 to fix the labels 60 when the adhesive rollers 20 are applying adhesive. The label pressure rollers 50 can fix the labels 60 when the adhesive rollers 20 are applying adhesive 40, preventing the labels 60 from shaking during application and ensuring a good adhesive application effect. Furthermore, multiple label pressure rollers 50 are provided, ensuring that each adhesive roller 20 has a corresponding label pressure roller 50 to cooperate with during adhesive application, thereby guaranteeing a good adhesive application effect and improving adhesive application efficiency.

[0048] In summary, the glue application device in this embodiment can not only accurately control the amount of glue applied, ensuring a good glue application effect and improving the degree of automation, but also ensure good packaging efficiency and packaging yield.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
