Description

Technical Field

[0001] The utility model relates to the technical field of transparent tape production, and particularly relates to a glue coating device. Background Art

[0002] A transparent tape is a transparent adhesive tape, usually composed of a transparent film substrate and an adhesive. It has a wide range of uses in many daily life and office occasions. Transparent tapes are usually easy to tear and use, and do not leave residues after use. It is a very convenient multi-functional tool that can play a role in various daily situations.

[0003] For example, the Chinese utility model patent (CN219291872U) discloses a glue coating device for transparent tape production, which records: "Through the arrangement of the reciprocating screw rod and the moving scraping strip, the glue remaining on the scraping plate is pushed to both sides, so that it is separated from the scraping plate, avoiding the influence on the tape production due to the accumulation of glue, and at the same time avoiding the remaining glue from solidifying on the scraping plate." It also records the technical problem: "In the existing glue coating device for transparent tape production, after applying glue to the tape, in order to make the glue on the tape uniform, a scraping plate is usually set to remove the excess glue on the tape. However, during use, glue will accumulate on the scraping plate. If this glue is not removed, it will re-accumulate on the tape, affecting the cleaning effect of the excess glue, and if not removed, the glue will solidify, making subsequent cleaning more troublesome."

[0004] In summary, it can be seen that in the prior art, a moving scraping strip is used to clean the glue on the scraping plate to avoid affecting the tape production due to the accumulation of glue. However, this method has the following technical problems: during the use of the device, after applying glue and using the scraping plate to remove the excess glue, since the glue is not dried, it is easy to cause the tape to be damaged during transmission due to the un-solidified glue, resulting in uneven distribution of the final glue. Therefore, this application proposes a glue coating device to provide a new technical solution to solve the technical problems mentioned in the above patent. Summary of the Utility Model

[0005] Based on this, it is necessary to provide a gluing device for the above-mentioned technical problems. The rotation of the incomplete gear can drive the rack to move a certain distance to one side, thereby compressing the spring. Then, when the incomplete gear is in a toothless state, the rack returns to its initial position under the action of the spring force. Furthermore, the rack finally makes a reciprocating motion under the restriction of the two fixed frames. Then, the large gear drives the small gear to rotate forward and backward, and finally drives the fan blade to move, thereby generating a certain amount of wind to dry the glue on the tape, avoiding the situation that the tape is scratched or squeezed during the transmission process due to the glue not being dried. The glue is initially dried, improving the stability of tape gluing. Moreover, the power for drying the tape by the drying mechanism and cleaning the scraper both comes from the driving motor, avoiding the need to set up an additional power source for the device, thereby reducing the production cost of the device.

[0027] To enable those skilled in the art to better understand the solution of the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0028] As described in the background art, during the use of the device, after applying glue and using a squeegee to remove the excess glue, since the glue has not dried, it is easy to cause the tape to be damaged during transmission due to the un-solidified glue, resulting in uneven distribution of the final glue.

[0029] To solve this technical problem, the present utility model provides a gluing device, which is applied to gluing during the production of transparent tape.

[0030] Specifically, please refer to Figure 1 - Figure 2 , the gluing device specifically includes:

[0031] A device base 1, a cleaning mechanism 4 is arranged on the top of the device base 1, a drying mechanism 5 is arranged on the cleaning mechanism 4, a gluing machine 2 is fixedly installed on the top of the device base 1 and on one side of the cleaning mechanism 4, and a conveying member 3 is fixedly installed on the top of the device base 1 and on the side of the cleaning mechanism 4 away from the gluing machine 2;

[0032] The drying mechanism 5 includes a support frame 6, a driving motor 7, a first threaded rod 8, a transmission component, and a blowing component. The top of the device base 1 is fixedly connected to the support frame 6, the outer wall of the driving motor 7 is fixedly installed with the driving motor 7, the first threaded rod 8 is rotatably connected inside the support frame 6, and one end of the first threaded rod 8 is fixedly connected to the output end of the driving motor 7.

[0033] When the present device is in use, it needs to cooperate with a tape feeding device and a winding device. The specific installation method is to place the tape feeding device at the feeding end of the gluing machine 2, and the winding device is located at the discharging end of the conveying member 3. Pass the tape on the feeding device through the gluing machine 2 and the cleaning mechanism 4, and pass through the middle of the two rollers on the conveying member 3, and finally fix it on the winding device. Since the tape feeding device, the winding device, the gluing machine 2, and the conveying member 3 all belong to the prior art, no further description will be made here.

[0034] The glue - applying device provided by the utility model can drive the rack 17 to move a certain distance to one side through the rotation of the incomplete gear 15, so that the spring 18 is compressed. Then, when the incomplete gear 15 is in a toothless state, the rack 17 returns to the initial position under the action of the elastic force of the spring 18. Thus, the rack 17 finally makes a reciprocating motion under the restriction of the two fixed brackets 16. Then, the large gear 20 drives the small gear 22 to rotate forward and backward, and finally drives the fan blade 23 to move, generating a certain amount of wind to air - dry the glue on the tape. This avoids the situation that the tape is scratched or squeezed during the transmission process due to the failure to air - dry the glue, initially air - dries the glue, improves the stability of tape glue - applying, and the power for the air - drying mechanism 5 to air - dry the tape and clean the squeegee 14 both comes from the driving motor 7, avoiding the need to additionally set a power source for the device, thereby reducing the production cost of the device.

[0035] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the accompanying drawings.

[0036] Embodiment 1:

[0037] Please refer to Figure 2 - Figure 5 , a glue - applying device, which includes:

[0038] The transmission component includes incomplete gears 15 fixedly connected to the outer wall of the first threaded rod 8 and respectively near the two side edges. Two fixed brackets 16 are fixedly connected to the top of the device base 1. The inner walls of the two fixed brackets 16 are slidably connected with a rack 17. The rack 17 makes a reciprocating motion under the action of the incomplete gear 15 and the spring 18. The fixed brackets 16 provide stable support for the movement of the rack 17. The rack 17 meshes with the top of the incomplete gear 15. Springs 18 are respectively fixedly connected to both ends of the rack 17, and the ends of the two springs 18 far from the rack 17 are respectively fixedly connected to the inner walls of the fixed brackets 16.

[0039] The blowing component includes a first mounting plate 19 fixedly connected to the outer wall of the support frame 6. A large gear 20 is rotatably connected to the inner wall of the first mounting plate 19. The large gear 20 meshes with the bottom of the rack 17. A second mounting plate 21 is fixedly connected to the outer wall of the support frame 6. A small gear 22 is rotatably connected to the inner wall of the second mounting plate 21. The small gear 22 meshes with the bottom of the large gear 20. The size of the large gear 20 is larger than that of the small gear 22, so that when the large gear 20 rotates, it can drive the small gear 22 to rotate relatively faster with respect to the small gear 22, thereby improving the air - drying effect on the glue. The specific sizes of the large gear 20 and the small gear 22 can be changed according to the usage requirements. A fan blade 23 is fixedly connected to the side of the small gear 22 close to the middle of the support frame 6.

[0040] Through the above structural design, the driving motor 7 is started, which in turn drives the first threaded rod 8 to rotate. The rotation of the first threaded rod 8 causes the incomplete gear 15 to rotate accordingly. The incomplete gear 15 drives the rack 17 to move a certain distance under the restriction of the two fixed brackets 16. As a result, one of the springs 18 in the two fixed brackets 16 is stretched and the other is compressed. When the incomplete gear 15 reaches the toothless stage, the two springs 18 release their elastic force, driving the rack 17 back to the initial state, thereby realizing the reciprocating motion of the rack 17. With the movement of the rack 17, the large gear 20 rotates accordingly, which in turn drives the small gear 22 to rotate, and further causes the fan blade 23 to rotate, thereby driving the air flow to dry the glue on the tape.

[0041] Embodiment 2:

[0042] The gluing device provided in Embodiment 1 is further optimized. Specifically, as Figure 2 - Figure 4 shown, the cleaning mechanism 4 includes a threaded block 9, a scraping plate 14, a cleaning component, and a lifting component. The outer wall of the first threaded rod 8 is threadedly connected to the threaded block 9. The scraping plate 14 is slidably connected to the inner wall of the support frame 6. The two ends of the scraping plate 14 are long enough to be longer than the width of the produced tape, so as to facilitate scraping the glue on the tape to both sides of the tape.

[0043] The cleaning component includes two limiting rods 11 slidably connected to the inner wall of the threaded block 9. The bottom of the limiting rod 11 is fixedly connected to a cleaning block 10. The cleaning block 10 can scrape and clean both sides of the scraping plate 14, thereby improving the cleaning effect on the scraping plate 14. The cleaning block 10 is slidably connected to the outer wall of the scraping plate 14.

[0044] The lifting component includes a second threaded rod 12 rotatably connected to the inner wall of the support frame 6. The top of the second threaded rod 12 is fixedly connected to a handle, which facilitates rotating the second threaded rod 12 through the handle. A plurality of fixing rods 13 are fixedly connected to the inner wall of the support frame 6. The scraping plate 14 is threadedly connected to the outer wall of the second threaded rod 12. The scraping plate 14 is slidably connected to the outer wall of the fixing rod 13.

[0045] Through the above structural design, by driving the rotation of the first threaded rod 8 by the driving motor 7, the threaded block 9 can be driven to move accordingly under the restriction of the cleaning block 10, the limiting rod 11, and the scraping plate 14, thereby scraping the glue on the scraping plate 14, scraping the glue to both sides of the tape respectively, and finally falling into the receiving groove on the support frame 6. And by rotating the second threaded rod 12, the scraping plate 14 can be driven to move in height under the restriction of the fixing rod 13 and the support frame 6. At the same time, the limiting rod 11 slides in the inner wall of the threaded block 9.
