Abstract
Description
Technical Field
[0001] This utility model relates to the field of adhesive coating technology, specifically to an adhesive coating structure with adjustable coating thickness. Background Technology
[0002] In the existing field of adhesive coating technology, self-adhesive coating technology is widely used in the bonding and processing of various types of paper and materials. However, different types of paper have different requirements for the thickness of the adhesive coating. For example, smooth paper has low water absorption and usually only requires a thin adhesive coating to achieve effective bonding. On the other hand, paper with high water absorption or a rough surface requires a thicker adhesive layer to ensure bonding strength.
[0003] However, in some product applications, paper may be composed of multiple materials, and the water absorption and roughness of the spliced areas vary due to differences in material properties. If the gluing equipment cannot flexibly adjust the glue coating thickness according to the differences in the characteristics of local areas of the paper, it is easy to cause uneven coating, which will ultimately affect the stability and reliability of the bonding effect. Therefore, when dealing with spliced paper or multi-characteristic materials, it is difficult to meet the requirements for precise control of the glue coating in the production process. Utility Model Content
[0004] This invention addresses the technical problems existing in the prior art by providing an adjustable coating structure. This solves the problem that, due to the varying absorbency and roughness of paper, if the coating equipment cannot flexibly adjust the adhesive coating thickness according to the differences in local paper characteristics, uneven coating can easily occur, ultimately affecting the stability and reliability of the bonding effect.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: an adhesive coating structure with adjustable coating thickness, comprising:
[0006] Two opposing wall panels;
[0007] An adhesive roller, both ends of which are rotatably connected between two wall panels via rotating shafts;
[0008] A glue container is provided, located below the adhesive roller and positioned between two wall panels;
[0009] A linear module is disposed on the top of the wall panel, and the moving end of the linear module moves closer to or further away from the adhesive roller along the top edge of the wall panel.
[0010] A column, which is fixed to the moving end of the linear module;
[0011] Connecting arm, which is fixed between the columns;
[0012] A slide groove is formed on one side of the connecting arm;
[0013] At least one set of scraping structures slides on the groove of the connecting arm, wherein one set of scraping structures includes a scraper blade, and the width of the scraper blade is less than the length of the adhesive roller axis.
[0014] The beneficial effects of this utility model are:
[0015] 1) By setting the scraper structure in the groove of the connecting arm, and using the moving end of the linear module to drive the column and connecting arm to move closer to the adhesive roller along the top edge of the wall panel, the distance between the scraper and the adhesive roller can be flexibly adjusted according to actual needs. This allows for precise scraping of the adhesive adhering to the outside of the adhesive roller, reducing the adhesive thickness and ensuring that the adhesive layer matches the characteristics of the material during the coating process.
[0016] 2) Because the width of the squeegee is less than the length of the adhesive roller axis, and the squeegee can slide within the groove of the connecting arm, this device can specifically adjust the glue thickness of corresponding areas on the adhesive roller according to the water absorption or roughness of different areas on the paper. For example, for areas with weak water absorption, the squeegee can be moved to the adhesive roller to reduce the glue thickness and form a thinner glue coating. For areas with strong water absorption, a thicker glue layer is retained, without the need for squeegee scraping or by using a shorter squeegee to increase the distance between the squeegee and the glue coating in that area, ensuring bonding strength. This localized adjustment capability is suitable for processing scenarios involving splicing paper or combining multiple materials. In addition, when it is necessary to adjust the glue thickness of the entire adhesive roller, multiple sets of squeegees of the same size can be added in the groove of the connecting arm, so that the total width of the multiple sets of squeegees exceeds the length of the adhesive roller axis, thereby achieving uniform control of the glue thickness across the entire width of the adhesive roller.
[0017] Based on the above technical solution, the present invention can be further improved as follows.
[0018] Furthermore, one set of the adhesive scraping structures also includes a first slider, which slides in a groove.
[0019] Furthermore, one side of the scraper is fixed to one side of the slider.
[0020] Furthermore, an inclined surface is provided on one side of the scraper.
[0021] The beneficial effect of adopting the above-mentioned further solution is that, through the design of the inclined surface, the flow of glue can be guided more smoothly, reducing glue accumulation and splashing during the glue application process, and improving the uniformity of glue application.
[0022] Furthermore, the linear module includes a servo motor, a guide rail base, a lead screw, a second slider, and a nut, with the guide rail base fixed to the top of the wall panel.
[0023] Furthermore, the servo motor is fixed on one side of the guide rail mold base, one end of the lead screw is fixed on the drive end of the servo motor, and the other end of the lead screw is rotatably connected to the other side of the guide rail mold base through a rotating shaft. The nut is sleeved on the outside of the lead screw, the second slider slides outside the guide rail mold base, and the second slider is connected to the nut.
[0024] The beneficial effect of adopting the above-mentioned further solution is that the servo motor drives the lead screw to rotate. Due to the interaction between the threads, the nut drives the second slider to slide on the guide rail mold base, thereby driving the column and connecting arm to move closer to the adhesive roller along the top edge of the wall panel. This allows the distance between the scraper and the adhesive roller to be flexibly adjusted according to actual needs. Attached Figure Description

[0032] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0033] In the existing field of adhesive coating technology, self-adhesive coating technology is widely used in the bonding and processing of various types of paper and materials. However, different types of paper have different requirements for the thickness of the adhesive coating. For example, smooth paper has low water absorption and usually only requires a thin adhesive coating to achieve effective bonding. On the other hand, paper with high water absorption or a rough surface requires a thicker adhesive layer to ensure bonding strength.
[0034] However, in some product applications, paper may be composed of multiple materials, and the water absorption and roughness of the spliced areas vary due to differences in material properties. If the adhesive coating equipment cannot flexibly adjust the adhesive coating thickness according to the differences in the characteristics of local areas of the paper, it is easy to cause uneven coating, which ultimately affects the stability and reliability of the bonding effect. Therefore, when processing spliced paper or multi-characteristic materials, it is difficult to meet the requirements for precise control of the adhesive coating during the production process. To address this issue, the inventor has proposed an adjustable coating structure to solve the above problems.
[0035] The present invention provides the following preferred embodiments.
[0036] like Figures 1-5 As shown, an adjustable coating structure includes:
[0037] Two opposing wall panels 10;
[0038] Adhesive roller 20, both ends of which are rotatably connected between the two wall panels 10 via rotating shafts;
[0039] A glue box 30 with built-in glue is located below the glue roller 20 and is disposed between the two wall panels 10;
[0040] Linear module 80 is disposed on the top of wall panel 10. The moving end of linear module 80 moves along the top edge of wall panel 10 to approach or move away from adhesive roller 20.
[0041] Column 50 is fixed on the moving end of the linear module 80;
[0042] Connecting arm 60, connecting arm 60 is fixed between columns 50;
[0043] The slide 70 is formed on one side of the connecting arm 60;
[0044] At least one set of scraping structures 40 slides on the groove 70 of the connecting arm 60, wherein the scraping structure 40 includes a scraper 402, and the width of the scraper 402 is less than the axial length of the adhesive roller 20.
[0045] By setting the scraper structure 40 in the groove 70 of the connecting arm 60, and using the moving end of the linear module 80 to drive the column 50 and the connecting arm 60 to move along the top edge of the wall panel 10 closer to the adhesive roller 20, the distance between the scraper 402 and the adhesive roller 20 can be flexibly adjusted according to actual needs. This allows for precise scraping of the adhesive adhering to the outside of the adhesive roller 20, reducing the adhesive thickness and ensuring that the adhesive layer matches the characteristics of the material during the coating process.
[0046] Because the width of the squeegee 402 is less than the length of the axis of the adhesive roller 20, and the squeegee 402 can slide within the groove 70 of the connecting arm 60, this device can specifically adjust the adhesive thickness on the corresponding area of the adhesive roller 20 according to the water absorption or roughness of different areas on the paper. For example, for areas with weak water absorption, moving the squeegee 402 to the area of the adhesive roller 20 corresponding to the area of weak water absorption can reduce the adhesive thickness to form a thinner adhesive coating; while for areas with strong water absorption, a thicker adhesive layer is retained. Without the need for scraping with a squeegee 402 or using a shorter squeegee 402 to increase the gap between the squeegee 402 and the adhesive coating in this area, the bonding strength is ensured. The localized adjustment capability is suitable for processing scenarios involving splicing paper or combining multiple materials. In addition, when it is necessary to make overall adjustments to the adhesive thickness of the entire adhesive roller 20, multiple sets of squeegees 402 of the same size are added in the groove 70 of the connecting arm 60, so that the overall width of the multiple sets of squeegees 402 exceeds the axial length of the adhesive roller 20, thereby achieving uniform control of the adhesive thickness across the entire width of the adhesive roller 20.
[0047] In this embodiment, as Figures 1-5 As shown, a set of adhesive scraping structures 40 also includes a first slider 401, which slides in the groove 70, and one side of the adhesive scraper 402 is fixed on one side of the slider.
[0048] In this embodiment, as Figures 1-5 As shown, the glue scraper 402 has an inclined surface on one side. The inclined surface design can guide the glue flow more smoothly, reduce glue accumulation and splashing during the glue scraping process, and improve the uniformity of glue scraping.
[0049] In this embodiment, as Figures 1-5 As shown, the linear module 80 includes a servo motor 801, a guide rail base 804, a lead screw 802, a second slider 805, and a nut 803. The guide rail base 804 is fixed to the top of the wall panel 10. The servo motor 801 is fixed to one side of the guide rail base 804. One end of the lead screw 802 is fixed to the drive end of the servo motor 801, and the other end of the lead screw 802 is rotatably connected to the other side of the guide rail base 804 through a rotating shaft. The nut 803 is sleeved on the outside of the lead screw 802. The second slider 805 slides on the outside of the guide rail base 804 and is connected to the nut 803.
[0050] The servo motor 801 drives the lead screw 802 to rotate. Due to the interaction between the threads, the nut 803 drives the second slider 805 to slide on the guide rail mold base 804, thereby driving the column 50 and the connecting arm 60 to move closer to the adhesive roller 20 along the top edge of the wall panel 10. This allows the distance between the scraper 402 and the adhesive roller 20 to be flexibly adjusted according to actual needs.
[0051] The specific working process of this utility model is as follows:
[0052] First, prepare multiple glue scrapers 402 of the same size in advance, such as 20cm wide * 40cm long, and multiple glue scrapers 402 of different sizes, such as 15cm wide * 39.5cm long, 20cm wide * 39cm long, etc.
[0053] For areas with weak water absorption, move the 20cm wide x 40cm long scraper 402 to the adhesive roller 20 to the area of the paper with weak water absorption. The thickness of the adhesive can be reduced by the scraper 402 to form a thinner adhesive coating.
[0054] For areas with high water absorption, a thicker layer of adhesive is retained, without the need for scraping with a scraper 402 or by using a shorter scraper 402 (20cm wide x 39cm long) to increase the gap between the scraper 402 and the adhesive coating in that area.
[0055] Finally, the servo motor 801 drives the lead screw 802 to rotate. Due to the interaction between the threads, the nut 803 drives the second slider 805 to slide on the guide rail mold base 804, thereby driving the column 50 and the connecting arm 60 to move closer to the adhesive roller 20 along the top edge of the wall panel 10, so that the distance between the scraper 402 and the adhesive roller 20 can be flexibly adjusted according to actual needs.
[0056] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
