Description

Technical Field

[0001] This invention belongs to the field of extrusion and coating technology, and specifically relates to an apparatus for removing thick edges. Background Technology

[0002] Currently, thick edges are a common problem in slot extrusion and coating processes due to necking and surface tension. In extrusion lamination, thick edges prevent the middle layer of the film from adhering properly to the composite film, resulting in uneven lamination pressure and inconsistent peel strength. In coating, ensuring thorough drying of thick edges requires increasing drying temperature or extending drying time, which not only increases energy consumption but may also lead to false drying, causing adhesion during winding and severely impacting product quality. Summary of the Invention

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, the present invention provides a device for removing thick edges. Thus, this device allows for both coarse adjustment of the distance between the scraper and the thick edge to be treated, or the angle between the scraper and the thick edge, and precise adjustment of the angle between the scraper and the thick edge, as well as the distance between the scraper and the thick edge along the Z-direction. This makes it easier to remove excess melt / coating liquid from the thick edge area, ensuring the uniformity of the composite film / coating layer.

[0004] This invention proposes an apparatus for removing thick edges, comprising:

[0005] Fixing part;

[0006] The guide portion has a first guide hole along the Y direction on one side and a second guide hole along the Z direction. The guide portion is connected to one end of the fixing portion.

[0012] According to the embodiment of the present invention, the device for removing thick edges can roughly adjust the distance between the scraper and the thick edge to be treated, or the angle between the scraper and the thick edge to be treated, by adjusting the position of the fixing part; by setting the first guide rod to move in an arc shape along the XY plane on the guide part, thereby driving one end of the third guide rod to move in an arc shape along the XY plane, while the other end of the third guide rod is fixed in the fixing hole at the bottom of the second guide rod, thereby precisely adjusting the angle between the scraper and the thick edge to be treated; by setting the second guide rod to move along the Z direction on the guide part, thereby driving one end of the third guide rod to move along the Z direction, thereby precisely controlling the distance between the scraper and the thick edge to be treated along the Z direction. Therefore, the above device can both roughly adjust the distance between the scraper and the thick edge to be treated, or the angle between the scraper and the thick edge to be treated, and precisely adjust the angle between the scraper and the thick edge to be treated, and the distance between the scraper and the thick edge to be treated along the Z direction, thus making it easier to remove excess melt / coating liquid from the thick edge area and ensuring the uniformity of the composite film / coating layer.

Detailed Implementation

[0035] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0036] This invention proposes a device for removing thick edges. According to an embodiment of the invention, refer to the attached drawing. Figure 1-3The aforementioned device includes: a fixing part 1, which can be connected to a support member. By adjusting the position of the fixing part on the support member, the distance between the scraper and the thick edge to be processed or the angle between the scraper and the thick edge to be processed can be roughly adjusted; a guide part 2, which has a first guide hole 10 along the Y direction on one side and a second guide hole 11 along the Z direction, and is connected to one end of the fixing part; a first guide rod 3, which has a third guide hole at its bottom and passes through the first guide hole 10 on the guide part 2, and can move in an arc along the XY plane on the guide part 2; a second guide rod 4, which has a fixing hole at its bottom and passes through the second guide hole 11 on the guide part 2, and can move along the Z direction on the guide part 2; and a third guide rod 5, which passes through the upper... The third guide hole and the aforementioned fixing hole are described above. The third guide rod 5 is fixedly mounted on the second guide rod 4 through the aforementioned fixing hole, and the third guide rod 5 can move along the Z direction within the third guide hole. By setting the first guide rod 3 to move in an arc shape along the XY plane on the guide part 2, one end of the third guide rod 5 is driven to move in an arc shape along the XY plane, while the other end of the third guide rod 5 is fixed in the fixing hole at the bottom of the second guide rod 4, thereby allowing precise adjustment of the angle between the scraper 7 and the thick edge to be processed. By setting the second guide rod 4 to move along the Z direction on the guide part 2, one end of the third guide rod 5 is driven to move along the Z direction, thereby allowing precise control of the distance between the scraper 7 and the thick edge to be processed along the Z direction. The connecting rod 6 has one end connected to the third guide rod 5. The scraper 7 is connected to the other end of the connecting rod 6, so the position and angle of the scraper 7 can be controlled by controlling the position and angle of the third guide rod 5.

[0037] It should be noted that the area that the scraper can remove from the thick edge is generally larger than the area of ​​the thick edge itself. Therefore, after roughly adjusting the distance between the scraper and the thick edge to be treated, or the angle between the scraper and the thick edge, using the fixing part, generally only the angle between the scraper and the thick edge to be treated, and the distance between the scraper and the thick edge to be treated along the Z direction, need to be adjusted. The distance between the scraper and the thick edge to be treated along the X and Y directions usually does not need to be adjusted. The XY plane mentioned above refers to the plane formed by the X-axis and the Y-axis.

[0038] According to some specific embodiments of the present invention, refer to the appendix Figure 1 and 2It also includes a fixing member 8, which is used to fix the first guide rod 3 along the Z direction to the guide part 2. This ensures that when the first guide rod 3 moves along the Y direction on the guide part 2, the first guide rod 3 will not move along the Z direction, thereby driving one end of the third guide rod 5 to move in an arc shape along the XY plane. The other end of the third guide rod 5 is fixed in the fixing hole at the bottom of the second guide rod 4, so that the angle between the scraper 7 and the thick edge to be processed can be precisely adjusted.

[0039] In the embodiments of the present invention, the above-mentioned fastener 8 is not particularly limited, as long as it can fix the first guide rod along the Z direction on the guide. As a specific example, the above-mentioned fastener 8 can be a nut.

[0040] According to further specific embodiments of the present invention, see attached drawing. Figure 1 and 2 It also includes: a movable connecting device 9, which is connected between the guide part and the fixed part. The position of the fixed part does not change. Therefore, when the movable connecting device is loosened, the angle between the guide part and the fixed part can be adjusted. Finally, the movable connecting device is tightened, thereby realizing the adjustment of the angle between the scraper and the thick edge to be processed.

[0041] According to some specific embodiments of the present invention, the above-mentioned movable connecting device 9 is not particularly limited, as long as it can movably connect the guide part and the fixing part. As a specific example, the above-mentioned movable connecting device includes at least one of screw connection and bolt connection.

[0042] According to some specific embodiments of the present invention, see attached drawing. Figure 4 The first guide rod includes a first guide rod control end 12, a first guide rod wide diameter section 13, and a first guide rod narrow diameter section 14. The first guide rod control end is located at the top of the first guide rod, the first guide rod wide diameter section is located in the middle of the first guide rod, and the first guide rod narrow diameter section is located at the bottom of the first guide rod. The end of the first guide rod wide diameter section near the first guide rod narrow diameter section has an internal thread, and the end of the first guide rod narrow diameter section near the first guide rod wide diameter section has an external thread. One end of the first guide rod narrow diameter section can be screwed into one end of the first guide rod wide diameter section. The function of the first guide rod control end is to control the rotation of the first guide rod wide diameter section and the first guide rod narrow diameter section. Thus, by setting the first guide rod wide diameter section and the first guide rod narrow diameter section, the third guide rod can be better controlled to move in an arc shape along the XY plane. The other end of the third guide rod is fixed in the fixing hole at the bottom of the second guide rod, thereby allowing precise adjustment of the angle between the scraper and the thick edge to be processed.

[0043] Furthermore, there is a difference in the circumference of one revolution of the wide-diameter section and the narrow-diameter section of the first guide rod. If the area of ​​the thick edge is large, the difference between the diameters of the wide-diameter section and the narrow-diameter section of the first guide rod can be set smaller, so that it is easier to remove the thick edge by adjusting the control end of the first guide rod, thereby improving work efficiency. If the area of ​​the thick edge is small, the difference between the diameters of the wide-diameter section and the narrow-diameter section of the first guide rod can be set larger, so that it is better to remove the thick edge by adjusting the control end of the first guide rod, thereby increasing the accuracy of the thick edge removal work.

[0044] Further, see Appendix Figure 4 The diameter of the top end of the narrow diameter section 14 of the first guide rod is larger than that of the bottom end of the narrow diameter section 14 of the first guide rod. Therefore, it is easier to set the fastener at the top end of the narrow diameter section 14 of the first guide rod, so that the first guide rod is fixed on the guide part 2 along the Z direction.

[0045] Furthermore, the first guide hole is provided with a toothed structure (internal thread), and the wide diameter section of the first guide rod is provided with a matching toothed structure (external thread). The first guide hole and the wide diameter section of the first guide rod mesh with each other. This allows for better adjustment of the first guide rod 3's arc-shaped movement along the XY plane on the guide part 2, thereby enabling precise adjustment of the angle between the scraper 7 and the thick edge to be processed. The fixing member is provided with a toothed structure (internal thread), and the top end of the narrow diameter section of the first guide rod is provided with a matching toothed structure (external thread). The fixing member meshes with the top end of the narrow diameter section of the first guide rod. This makes it easier to place the fixing member at the top end of the narrow diameter section of the first guide rod, thereby fixing the first guide rod on the guide part along the Z direction.

[0046] According to some specific embodiments of the present invention, the difference between the diameter of the wide diameter section of the first guide rod and the diameter of the narrow diameter section of the first guide rod is 1-50mm. Thus, by controlling the difference between the diameter of the wide diameter section of the first guide rod and the diameter of the narrow diameter section of the first guide rod within the above range, both the efficiency of removing thick edges and the accuracy of the thick edge removal work can be guaranteed.

[0047] According to some specific embodiments of the present invention, see attached drawing. Figure 5The second guide rod includes a second guide rod control end 15, a second guide rod wide diameter section 16, and a second guide rod narrow diameter section 17. The second guide rod control end is located at the top of the second guide rod, the second guide rod wide diameter section is located in the middle of the second guide rod, and the second guide rod narrow diameter section is located at the bottom of the second guide rod. The end of the second guide rod wide diameter section near the second guide rod narrow diameter section has an internal thread, and the end of the second guide rod narrow diameter section near the second guide rod wide diameter section has an external thread. One end of the second guide rod narrow diameter section can be screwed into one end of the second guide rod wide diameter section. The function of the second guide rod control end is to control the rotation of the second guide rod wide diameter section and the second guide rod narrow diameter section. By setting a diameter difference between the second guide rod wide diameter section and the second guide rod narrow diameter section, the distance the third guide rod moves along the Z direction can be better controlled.

[0048] Furthermore, there is a difference in the circumference of one revolution of the wide-diameter section and the narrow-diameter section of the second guide rod. If the area with the thick edge is large, the difference between the diameters of the wide-diameter section and the narrow-diameter section of the second guide rod can be set smaller, making it easier to remove the thick edge by adjusting the control end of the second guide rod and improving work efficiency. If the area with the thick edge is small, the difference between the diameters of the wide-diameter section and the narrow-diameter section of the second guide rod can be set larger, making it easier to remove the thick edge by adjusting the control end of the second guide rod and increasing the accuracy of the thick edge removal work.

[0049] Furthermore, for example, if the circumference of one revolution of the wide diameter section of the second guide rod is 1cm and the circumference of one revolution of the narrow diameter section of the second guide rod is 0.75cm, then when the wide diameter section of the second guide rod moves 1cm in the negative Z-axis direction, the distance by which one end of the narrow diameter section of the second guide rod spirals into the other end of the wide diameter section of the second guide rod in the positive Z-axis direction is 0.75cm. This is equivalent to the third guide rod moving 0.25cm in the negative Z-axis direction. The connecting rod and scraper connected to the third guide rod also move 0.25cm in the negative Z-axis direction accordingly. Thus, precise control of the distance the third guide rod moves in the Z-direction is achieved, increasing the accuracy of the thick edge removal work.

[0050] Furthermore, the second guide hole is provided with a toothed structure (internal thread), and the wide diameter section of the second guide rod is provided with a toothed structure (external thread). The second guide hole meshes with the wide diameter section of the second guide rod, thereby better controlling the distance the third guide rod moves along the Z direction.

[0051] According to some specific embodiments of the present invention, the difference between the diameter of the wide diameter section of the second guide rod and the diameter of the narrow diameter section of the second guide rod is 0.01-0.5mm. Thus, by controlling the difference between the diameter of the wide diameter section of the second guide rod and the diameter of the narrow diameter section of the second guide rod within the above range, both the efficiency of removing thick edges and the accuracy of the thick edge removal work can be guaranteed.

[0052] In embodiments of the present invention, reference is made to the appendix. Figure 3 The first guide hole can be a waist-shaped hole, and the inside of the waist-shaped hole can be equipped with a gear structure to better control the first guide rod 3 to move in an arc shape on the guide part 2 along the XY plane, so as to accurately adjust the angle between the scraper and the thick edge to be processed.

[0053] According to some specific embodiments of the present invention, the diameter of the third guide hole is the same as the diameter of the first guide rod, so that the third guide rod remains fixed in the XY plane and moves only in the Z direction.

[0054] In the embodiments of the present invention, the specific structure of the third guide hole is not particularly limited, and those skilled in the art can choose according to specific circumstances. As a specific example, please refer to the appendix. Figure 6 The side view of the third guide hole is rectangular, and the width of the rectangle is the same as the diameter of the first guide rod. Therefore, it can be ensured that the third guide rod remains fixed in the XY plane and moves only in the Z direction.

[0055] In the embodiments of the present invention, the included angle between the waist-shaped hole (first guide hole) and the second guide hole is not particularly limited, and those skilled in the art can set it according to specific circumstances.

[0056] According to some specific embodiments of the present invention, see attached drawing. Figure 3 The angle between the waist-shaped hole (first guide hole) and the second guide hole is 0-20°. Therefore, by controlling the angle between the waist-shaped hole (first guide hole) and the second guide hole within the above range, the angle between the adjusting scraper and the thick edge to be processed can be guaranteed to be 0-20°, further increasing the accuracy of the thick edge removal work.

[0057] According to some specific embodiments of the present invention, the scraper 7 includes at least one of a curved scraper and a straight scraper. When the thick edge to be treated is on a regular, smooth straight surface, a straight scraper can easily remove excess melt / coating liquid from the thick edge area, ensuring the uniformity of the composite film / coating layer; however, when the coating device 18 is used for coating treatment, the coating liquid flows along the roller 19, and the thick edge to be treated formed by the coating liquid will be on an irregular curved surface, as shown in the attached figure. Figure 7 Using a curved scraper can better remove excess melt / coating liquid from thicker areas, ensuring the uniformity of the composite film / coating layer.

[0058] In the embodiments of the present invention, the thickness of the scraper along the Z direction is not particularly limited and can be selected according to the actual situation. When the viscosity of the melt / coating liquid forming the thick edge is large, the thickness of the scraper along the Z direction can be large, which can improve the scraping efficiency. When the viscosity of the melt / coating liquid forming the thick edge is low, the thickness of the scraper along the Z direction can be small, which can ensure the scraping accuracy.

[0059] According to some specific embodiments of the present invention, the thickness of the scraper 7 along the Y direction is 0.01-3 mm. Thus, by controlling the thickness of the scraper along the Z direction within the above range, excess melt / coating liquid in the thick edge area can be better removed, ensuring the uniformity of the composite film / coating layer.

[0060] According to some specific embodiments of the present invention, the material of the fixing part can be a magnetic material. The magnetic fixing part (magnetic suction table) can be more easily connected to the support (magnetic table). By adjusting the position of the magnetic fixing part on the magnetic table, the distance between the scraper and the thick edge to be processed or the angle between the scraper and the thick edge to be processed can be more easily adjusted.

[0061] According to further embodiments of the present invention, the above-mentioned device for removing thick edges is applied in extrusion lamination and coating fields. Using this device, excess melt / coating liquid at the thick edges can be scraped to both sides, making the overall transverse thickness of the composite film / coating layer more uniform. In the extrusion lamination field, when the composite film with its thick edges removed by the above-mentioned device is laminated with an intermediate film layer, the composite film and the intermediate film layer adhere uniformly, experience uniform pressure, and have equal peel strength, which is beneficial to improving the quality of subsequent products. In the coating field, the above-mentioned device can eliminate drying and winding problems caused by thick edges.
