Description

Technical Field

[0001] The invention relates to the technical field of adhesive tape gluing, and in particular to a precise gluing device for adhesive tape production. Background Art

[0002] Adhesive tape is an item used to stick different objects together. It is composed of a base material and glue (pressure-sensitive adhesive) applied on it. Gluing occupies an absolutely important position in the production process of adhesive tape. It can be said that the quality of glue coating directly affects the output quality of adhesive tape. Currently, glue rollers are usually used to directly apply glue to the base material (surface coating), and then the glue on the base material is cured by blowing cold air.

[0003] In the process of coating glue on the substrate, the existing glue coating device only uses the glue coating roller to directly coat the entire substrate with glue. In order to improve the uniformity and amount of glue coating, the glue on the substrate is scraped with a scraper. In this way, the glue will penetrate into the lower side of the substrate. The glue soaked into the lower side of the substrate will cause the adhesive tapes to adhere to each other after the subsequent winding, ultimately reducing the production quality of the adhesive tape. At the same time, in the process of curing the glue with cold air in the existing device, the liquid glue will undergo additional movement due to the wind, resulting in uneven distribution of the glue on the substrate, reducing the production quality of the adhesive tape.

[0029] In the process of coating glue on the substrate, the existing glue coating device uses a glue coating roller to directly coat the entire substrate with glue, and then scrapes the glue on the substrate with a scraper. In this way, the glue will penetrate into the lower side of the substrate. The glue that penetrates into the lower side of the substrate will cause the tapes to stick to each other after the subsequent winding is completed, ultimately reducing the production quality of the tape.

[0030] Embodiment 1: A precise glue coating device for producing adhesive tape, such as Figure 1-Figure 5As shown, it includes a frame 1, a material storage shell 2 is fixedly connected to the upper side of the frame 1, a motor 3 is installed at the middle and upper part of the rear side of the frame 1 through a mounting frame, and a glue coating roller 4 fixedly connected to the output shaft of the motor 3 is rotatably connected to the middle part of the frame 1, and the glue coating roller 4 is provided with a plurality of coating grooves 5 in a ring array, the coating grooves 5 are folded, and the coating grooves 5 are deflected counterclockwise from the front and rear ends to the middle part (in the normal view direction), and the length of the coating grooves 5 is less than the length of the glue coating roller 4. The coating grooves 5 are used to limit the glue in the adjacent areas, so that the glue is evenly coated on the substrate 101, and it is also ensured that the glue does not penetrate into the lower side of the substrate 101, thereby improving the production quality of the tape, and a first support plate 6 is fixedly connected to the middle part of the frame 1, and the first support plate 6 is an arc plate, and the center of the first support plate 6 is aligned with the glue coating roller 4 coincides, a fixed shaft 7 fixedly connected to the frame 1 is rotatably connected in the glue coating roller 4, a first tube 8 is connected between the storage shell 2 and the fixed shaft 7, a first pump 9 connected to the first tube 8 is installed on the front part of the upper side of the storage shell 2, a first cavity 10 exists between the glue coating roller 4 and the fixed shaft 7, the glue coating roller 4 is provided with a plurality of first holes 11 in an annular array, the first hole 11 is connected to the first cavity 10, the fixed shaft 7 is provided with four second holes 12 in an annular array, a second cavity 13 connected to the first tube 8 is provided in the fixed shaft 7, the second hole 12 is connected to the second cavity 13 and the first cavity 10, a retracting mechanism for retracting and releasing the substrate 101 is provided in the middle and lower part of the frame 1, and a scraping mechanism for flattening the glue on the substrate 101 is provided in the middle part of the frame 1.

[0031] like Figure 1 and Figure 4 As shown, the retracting mechanism includes a release roller 1401, which is installed on the left side of the frame 1, a first support roller 1402 is rotatably connected to the upper left portion of the frame 1, a second support roller 1403 is rotatably connected to the upper right portion of the frame 1, a winding roller 1404 is installed on the lower right portion of the frame 1, and the winding roller 1404 is an electric roller. A second support plate 1405 fixed to the first support plate 6 is fixed to the middle and upper portion of the frame 1, and the second support plate 1405 is in contact with the second support roller 1403. The contact between the second support plate 1405 and the second support roller 1403 is used to reduce the suspended area of ​​the substrate 101, thereby preventing the substrate 101 from bending under the action of its own gravity and the gravity of the glue, thereby affecting the production quality of the tape.

[0032] like Figure 6 and Figure 7As shown, the scraping mechanism includes a guide plate 1501, which is fixed to the upper right part of the frame 1, and a movable frame 1502 is slidably connected to the upper side of the guide plate 1501, and a scraper 1503 is fixed to the lower side of the movable frame 1502. The scraper 1503 is used to scrape off excess glue on the substrate 101, so as to quantitatively process the glue on the substrate 101, improve the accuracy of gluing the substrate 101, and thus improve the quality of the tape. A recovery component for collecting excess glue on the substrate 101 is provided on the upper side of the storage shell 2, and the recovery component includes a second pump 1601, which is installed and connected to the middle part of the upper side of the storage shell 2, and the second pump 1601 is connected to two second tubes 1602 arranged in front and back mirror images, and the height of the lower end of the second tube 1602 is higher than the height of the scraper 1503, and an adjustment component for changing the relative position of the guide plate 1501 and the movable frame 1502 is provided on the upper right part of the frame 1.

[0033] like Figure 6 and Figure 7 As shown, the adjustment component includes a rotating shaft 1701, which is rotatably connected to the upper right part of the frame 1, and a handle is provided at the front of the rotating shaft 1701. The lower side of the scraper 1503 is provided with two inclined surfaces arranged in front and back mirror images. The inclined surface gradually inclines to the right from top to bottom, and the inclination of the inclined surface on the scraper 1503 gradually increases from the outside to the inside, which is used to gather the glue on the substrate 101 to the middle. The middle part of the rotating shaft 1701 is threadedly connected to a limit plate 1702 that is slidably connected to the guide plate 1501. The limit plate 1702 is slidably connected to the guide plate 1501 by rotating the rotating shaft 1701. The plate 1702 slides relative to the guide plate 1501, and the upper side of the limiting plate 1702 is fixedly connected to the limiting rod 1703. The movable frame 1502 is provided with a limiting groove 1704 which cooperates with the limiting rod 1703. The limiting groove 1704 is used to limit the limiting rod 1703, so that when the limiting rod 1703 slides in the limiting groove 1704, the movable frame 1502 is squeezed, thereby changing the distance between the scraper 1503 and the upper side surface of the substrate 101, changing the distance between the scraper 1503 and the upper side surface of the substrate 101, and thereby increasing the application range of the device.

[0034] When it is necessary to use the present device to coat the substrate 101 with glue, the staff pours the prepared glue into the storage shell 2, then pulls the substrate 101 wound on the release roller 1401 to the right to release it, and makes the substrate 101 bypass the upper side of the first support roller 1402, and then makes the substrate 101 pass between the glue coating roller 4 and the first support plate 6, and then continues to pull the substrate 101 to the right, and makes the substrate 101 pass on the upper side of the second support plate 1405, and then makes the substrate 101 bypass the right side of the second support roller 1403, and finally makes the substrate 101 connected with the winding roller 1404. After the substrate 101 is wound, the staff starts the motor 3, the first pump 9, the release roller 1401 and the winding roller 1404, the output shaft of the motor 3 starts to rotate counterclockwise (in the front view direction), the first pump 9 starts to extract the glue in the storage shell 2, the release roller 1401 starts to rotate clockwise, and the winding roller 1404 starts to rotate counterclockwise.

[0035] During the counterclockwise rotation of the output shaft of the motor 3, the output shaft of the motor 3 drives the glue coating roller 4 to rotate counterclockwise together. During the process, the first pump 9 inputs the extracted glue into the second cavity 13 through the first tube 8. As the first pump 9 continues to extract the glue in the storage shell 2, the glue in the second cavity 13 gradually moves backward until the glue moves backward through the adjacent second hole 12 and enters the first cavity 10. Then, the glue is discharged from the glue coating roller 4 through the adjacent first hole 11. During the rotation process, the glue coating roller 4 applies the glue to the middle of the substrate 101. As the glue coating roller 4 continues to rotate counterclockwise, the coating groove 5 applies the glue to the adjacent area. The glue is squeezed toward the front and rear sides of the substrate 101 (the linear speed of the outer edge of the glue coating roller 4 is greater than the speed of the substrate 101 moving to the right), so that the glue is evenly distributed on the substrate 101. Since the length of the coating groove 5 is less than the length of the glue coating roller 4, the coating groove 5 has a limit position for squeezing the glue in the adjacent area (the glue will not overflow from the front and rear sides of the substrate 101). Under the premise of ensuring the uniformity of the glue coating, the glue is prevented from overflowing from the two sides of the substrate 101, and the glue is soaked into the lower side of the substrate 101, thereby causing mutual adhesion during the subsequent winding of the produced tape, thereby reducing the production quality of the tape.

[0036] While the glue coating roller 4 is coating the substrate 101 with glue, the winding roller 1404 continues to wind up the substrate 101, and the coated substrate 101 continues to pass the second support plate 1405 to the right. When there is more glue on the substrate 101, the coating groove 5 rotates counterclockwise until it contacts the glue. The coating groove 5 will gather and transfer the excess glue, and make the excess glue supplement other areas with relatively less glue, so as to further improve the uniformity of the glue coating on the substrate 101.

[0037] In order to improve the accuracy of gluing the substrate 101, the scraper 1503 is used to scrape off the excess glue on the substrate 101, so as to ensure the amount of glue applied to the substrate 101, improve the accuracy of gluing, and thus improve the product quality of the produced tape. The detailed steps are as follows. In the process of gluing the substrate 101, when the substrate 101 coated with glue by the glue coating roller 4 moves to the right on the upper side of the second support plate 1405 and passes through the scraper 1503, the scraper 1503 scrapes off the excess glue on the substrate 101 and gathers the glue to the middle under the action of the inclined surface on the lower side of the scraper 1503, so as to quantitatively process the glue on the substrate 101, improve the accuracy of gluing the substrate 101, and thus improve the quality of the tape.

[0038] During the process of coating the substrate 101 with glue, the staff starts the second pump 1601, and the second pump 1601 extracts the medium in the two second tubes 1602, generating negative pressure in the second tubes 1602. As the scraper 1503 scrapes the excess glue on the substrate 101 for a longer time, the excess glue gradually gathers in the middle, and the height of the accumulated glue in the middle area gradually increases. When the accumulated glue moves upward to contact the adjacent second tube 1602, under the action of the negative pressure in the second tube 1602, the accumulated glue begins to move upward along the adjacent second tube 1602, and finally the excess glue re-enters the storage shell 2.

[0039] In order to improve the application range of the device, the limit rod 1703 moving backward is used to move in the limit groove 1704 and press the movable frame 1502 downward to adjust the distance between the scraper 1503 and the upper side of the substrate 101. The detailed steps are as follows: when it is necessary to reduce the thickness of the glue on the substrate 101, the staff rotates the handle counterclockwise, and the handle drives the rotating shaft 1701 to rotate counterclockwise together. Then, under the action of the rotating shaft 1701, the limit plate 1702 starts to slide backward along the guide plate 1501, and the limit plate 1702 drives the limit plate 1702 to rotate counterclockwise. The rod 1703 moves backward together, the limiting rod 1703 slides in the limiting groove 1704 and presses the movable frame 1502 downward, the movable frame 1502 drives the scraper 1503 to move downward together, the movable frame 1502 and the guide plate 1501 slide relative to each other, and the distance between the scraper 1503 and the upper side of the substrate 101 is reduced, thereby reducing the amount of glue applied to the substrate 101 and increasing the application range of the device. When all substrates 101 are finished being coated with glue, the staff can turn off the motor 3, the first pump 9, the release roller 1401 and the winding roller 1404.

[0040] Embodiment 2: Based on embodiment 1, Figure 8-Figure 11As shown, it also includes a blower mechanism for curing the material, the blower mechanism is arranged on the right side of the frame 1, and the blower mechanism includes a wind casing 1801, the wind casing 1801 is fixed to the right side of the frame 1, the wind casing 1801 gradually tilts downward from left to right, and a cold air blower 1802 is installed on the upper side of the wind casing 1801 through a mounting frame, and an intermediate roller 1803 is rotatably connected to the right side of the frame 1, and a plurality of evenly arranged air outlet pipes 1804 are connected to the lower side of the wind casing 1801, and a tangent line on the upper side between the second support roller 1403 and the intermediate roller 1803 (the tangent line is The intermediate roller 1803 is parallel to the air passing shell 1801) and has an angle with the axis of the air outlet pipe 1804 and the horizontal plane (the air outlet pipe 1804 is gradually tilted to the left from top to bottom compared to the air passing shell 1801), which is used to blow the glue on the substrate 101 obliquely, so that the gravity of the glue due to the tilt and the wind force from the air outlet pipe 1804 offset each other, preventing the glue from changing its position due to the wind, thereby reducing the uniformity of the glue on the substrate 101. The intermediate roller 1803 is provided with a third cavity 1805 and a fourth cavity 1806. The air passing shell 1801 and the third cavity 1805 are parallel to the air passing shell 1801. There are two third tubes 1807 arranged in a front-to-back mirror image, and the middle roller 1803 is provided with a plurality of groups of third holes 1808 arranged equidistantly, each group contains four third holes 1808 in a circular array, and the third holes 1808 are connected to the third cavity 1805 and the fourth cavity 1806. The middle roller 1803 is rotatably connected with two connecting pieces 1809 arranged in a front-to-back mirror image, and the connecting piece 1809 is fixedly connected to the adjacent third tube 1807. The middle roller 1803 is provided with four evenly arranged air outlet channels 1810, and the air outlet channels 1810 are "L" shaped. The channel 1810 is connected to the fourth cavity 1806, and the opening diameters of the opposite sides of the two adjacent front and rear air outlet channels 1810 are smaller than the opening diameters of the back sides, which is used to delay the loss of cold air in the fourth cavity 1806 and fully solidify the glue on the substrate 101. The air outlet channel 1810 is located on the inner side of the fourth cavity 1806, and a thermal insulation material is provided in the middle roller 1803. The thermal insulation material is rubber and is located between the air outlet channel 1810 and the third cavity 1805. It is used to isolate the heat transfer between the third cavity 1805 and the air outlet channel 1810.

[0041] When it is necessary to apply glue to the substrate 101, the staff pulls the substrate 101 on the upper side of the second support plate 1405 to the right, so that the substrate 101 passes around the right side of the second support roller 1403, and finally connects the substrate 101 with the winding roller 1404. Then the staff starts the motor 3, the first pump 9, the release roller 1401, the winding roller 1404 and the cold air machine 1802, and starts the gluing work on the substrate 101. The cold air machine 1802 starts to blow cold air into the air casing 1801. A part of the cold air in the air casing 1801 is then blown to the adjacent area on the substrate 101 through the adjacent air outlet pipe 1804, and then the adjacent area on the substrate 101 is blown. The glue is solidified by gradually tilting the tangent line on the upper side between the second support roller 1403 and the middle roller 1803 downward from left to right, so that the substrate 101 is tilted synchronously, so that the glue on the inclined area of ​​the substrate 101 has a tendency to move downward, and then the cold wind blown out from the air outlet pipe 1804 tilted to the left from the upper right to the lower left is used to blow the glue in the adjacent area on the substrate 101, and the cold wind from the air outlet pipe 1804 offsets the gravity on the glue on the substrate 101, so as to ensure the force balance of the glue during the curing process, avoid additional movement of the glue when blown by the cold wind, thereby reducing the uniformity of the glue coating on the substrate 101.

[0042] During the counterclockwise rotation of the winding roller 1404, the winding roller 1404 drives the middle roller 1803 to rotate clockwise through the substrate 101, and the middle roller 1803 and the two connecting members 1809 rotate relative to each other. During the operation of the air cooler 1802, another part of the cold air in the air shell 1801 enters the third cavity 1805 through the adjacent third tube 1807, and the cold air in the third cavity 1805 enters the fourth cavity 1806 through the adjacent third hole 1808. At the same time, the cold air cools the outer side of the middle roller 1803, thereby The glue in adjacent areas on the substrate 101 is solidified. The cold air from the air outlet pipe 1804 solidifies the glue from the outside to the inside, and the middle roller 1803 solidifies the glue from the inside to the outside, so that the glue on the substrate 101 is evenly solidified to prevent the different degrees of solidification in different areas of the glue layer due to a single heat conduction path, thereby affecting subsequent storage. As the cold air gradually moves toward the middle in the fourth cavity 1806, when the cold air moves to the adjacent air outlet channel 1810, the cold air is discharged from the middle roller 1803 through the adjacent air outlet channel 1810.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
