Description

Technical Field

[0001] This utility model relates to the field of adhesive coating equipment technology, specifically to a high-precision, leak-proof adhesive coating equipment. Background Technology

[0002] The process of uniformly applying adhesive (including solvent-based adhesive, latex, and water-based adhesive) to the surface of a fabric involves four methods: scraping, rolling, dipping, and spraying. These methods often require the use of adhesive application tools. Currently, the adhesive application wheel is a common tool used for coatings.

[0003] A Chinese patent discloses a leak-proof adhesive application tool (authorization announcement number CN217774677U). The inner cavity of the coating holder can be filled with coating material, which drips slowly into the coating wheel through the seat perforation, wetting the end of the coating wheel with coating material. The coating wheel and the coating holder are movable and connected, which facilitates the operation of the coating holder and the rolling of the coating wheel to process the coating on the end of the workpiece.

[0004] In the above device, the paint drips slowly into the coating wheel through the seat hole under the action of gravity. However, the seat hole is not equipped with a leak-proof mechanism. When the coating wheel corresponding to the seat hole is partially saturated with adhesive, the paint can easily leak from the gap between the seat hole and the coating wheel, which will still cause paint waste.

[0005] Based on this, this utility model designs a high-precision, leak-proof adhesive application device to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a high-precision leak-proof adhesive application device.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A high-precision, leak-proof adhesive application device includes an adhesive storage tank. The bottom of the adhesive storage tank is fixedly connected to and communicates with an installation frame. An adhesive application wheel is rotatably connected to the inner side of the installation frame. A transfer cavity is opened on the inner side of the installation frame. A quantitative release mechanism fixedly connected to the adhesive application wheel is installed inside the transfer cavity.

[0009] Furthermore, the quantitative release mechanism includes a rotating wheel inside the transfer chamber, the surface of the rotating wheel is provided with a material collection groove, one end of the rotating wheel passes through the transfer chamber and extends to the outside of the mounting frame, a driven pulley is fixedly connected to the surface of the rotating wheel, a belt is drivenly connected to the surface of the driven pulley, and a driving pulley fixedly connected to the glue-applying wheel is drivenly connected to the inner side of the belt.

[0010] Furthermore, the number of the material collection troughs is no less than ten and they are arranged in a ring around the axis of the rotating wheel. The uppermost and lowermost material collection troughs are aligned with the upper and lower connecting points of the transfer cavity and the mounting frame, respectively.

[0011] Furthermore, the vertical cross-sectional shapes of the transfer cavity and the rotating wheel are both matching circles, and the inner diameters of the two connecting points between the transfer cavity and the mounting frame are both smaller than the diameter of the rotating wheel.

[0012] Furthermore, the quantitative release mechanism also includes a positioning component, which includes a connecting frame fixedly connected to the other end of the glue-applying wheel, and a positioning pin that is slidably connected to the inner side of the connecting frame and inserted into the mounting frame.

[0013] Furthermore, the surface of the mounting frame is provided with a positioning groove, and one end of the positioning pin is inserted into the positioning groove.

[0014] Furthermore, the number of positioning grooves is no less than ten and they are arranged in a ring around the axis of the coating wheel, and one end of the positioning pin is inserted into the lowest positioning groove.

[0015] Furthermore, an anti-detachment block with a diameter larger than the inner diameter of the connecting frame is fixedly connected between the positioning pins, and the anti-detachment block is disposed between the connecting frame and the positioning groove.

[0016] Furthermore, an adjusting ring is fixedly connected to the other end of the positioning pin, and the inner diameter of the adjusting ring is larger than the diameter of the connecting frame.

[0017] Beneficial effects

[0018] 1. During the rotation of the glue-applying wheel, the metering release mechanism can simultaneously drive the glue tank to quantitatively distribute the glue on the surface of the glue-applying wheel. The glue-applying rate will also increase or decrease with the glue-applying wheel's rotation speed. This not only improves the glue dispensing accuracy, but also reduces the probability of glue leakage between the glue-applying wheel and the mounting frame due to excessive glue, thus achieving the effect of saving glue.

[0019] 2. The staff can quickly lock the glue-applying wheel inside the mounting frame using the positioning component, preventing the glue-applying wheel from rotating when not in use. At the same time, this also firmly locks the wheel inside the transfer cavity, stopping the glue from being dispensed and further reducing the probability of glue being wasted.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-4A high-precision, leak-proof adhesive application device includes an adhesive storage tank 100. A mounting frame 200 is fixedly connected and communicates with the bottom of the adhesive storage tank 100. An adhesive application wheel 300 is rotatably connected to the inner side of the mounting frame 200. A transfer cavity 210 is opened on the inner side of the mounting frame 200. A quantitative release mechanism 400, fixedly connected to the adhesive application wheel 300, is installed inside the transfer cavity 210. A handle is fixedly connected to the surface of the adhesive storage tank 100. During use, the operator moves the adhesive storage tank 100 by using the handle, and the adhesive storage tank 100 drives the adhesive application wheel 300 to rotate and apply adhesive through the mounting frame 200.

[0030] The quantitative release mechanism 400 includes a rotating wheel 410 inside a transfer chamber 210. A collection trough 411 is formed on the surface of the rotating wheel 410. One end of the rotating wheel 410 passes through the transfer chamber 210 and extends to the outside of the mounting frame 200. A driven pulley 420 is fixedly connected to the surface of the rotating wheel 410. A belt 430 is drivenly connected to the surface of the driven pulley 420. A driving pulley 440, fixedly connected to the glue-applying wheel 300, is drivenly connected to the inner side of the belt 430. The number of collection troughs 411 is not less than [number missing]. Ten material collection troughs are arranged in a ring around the axis of the rotating wheel 410. The uppermost and lowermost material collection troughs 411 are aligned with the upper and lower connecting points of the central transfer cavity 210 and the mounting frame 200, respectively. The vertical cross-sectional shapes of the central transfer cavity 210 and the rotating wheel 410 are both matching circles. The inner diameters of the upper and lower connecting points of the central transfer cavity 210 and the mounting frame 200 are both smaller than the diameter of the rotating wheel 410. This can shorten the glue discharge interval and make the glue more evenly distributed on the surface of the glue-applying wheel 300.

[0031] In this embodiment of the invention, when the worker rotates the applicator wheel 300, the applicator wheel 300 drives the drive pulley 440 to rotate, the drive pulley 440 drives the belt 430 to drive the transmission, the belt 430 drives the driven pulley 420 to rotate, the driven pulley 420 drives the rotating wheel 410 to rotate, and the rotating wheel 410 drives all the collecting troughs 411 to rotate. When the collecting trough 411 is connected to the upper part of the mounting frame 200 through the transfer cavity 210, the collecting trough 411 is connected to the glue storage tank 100. Under the action of gravity, the glue inside the glue storage tank 100 flows into and fills the collecting trough 41. 1. Then, the roller 410 carries the glue downward through the collection trough 411. When the collection trough 411 containing the glue is connected to the lower part of the mounting frame 200 through the transfer cavity 210, the glue is unobstructed and flows to the surface of the glue-applying roller 300 under the action of gravity, so that the surface of the glue-applying roller 300 is quantitatively coated with glue. The glue-applying rate will also increase or decrease with the glue-applying speed of the glue-applying roller 300. This can not only improve the glue dispensing accuracy, but also reduce the probability of glue leakage between the glue-applying roller 300 and the mounting frame 200 due to excessive glue, so as to achieve the effect of saving glue.

[0032] In some embodiments, such as Figure 4As shown, in a preferred embodiment of this utility model, the quantitative release mechanism 400 further includes a positioning component 450. The positioning component 450 includes a connecting frame 451 fixedly connected to the other end of the glue-applying wheel 300. A positioning pin 452 that is inserted into the mounting frame 200 is slidably connected to the inner side of the connecting frame 451. A positioning groove 220 is provided on the surface of the mounting frame 200. One end of the positioning pin 452 is inserted into the positioning groove 220. The number of positioning grooves 220 is not less than ten and they are arranged in a ring around the axis of the glue-applying wheel 300. One end of the positioning pin 452 is inserted into the lowermost positioning groove 220. An anti-detachment block 453 with a diameter larger than the inner diameter of the connecting frame 451 is fixedly connected between the positioning pins 452. The anti-detachment block 453 is disposed between the connecting frame 451 and the positioning groove 220. An adjusting ring 454 is fixedly connected to the other end of the positioning pin 452. The inner diameter of the adjusting ring 454 is larger than the diameter of the connecting frame 451.

[0033] In this embodiment of the utility model, after the worker finishes using the glue-applying wheel 300, the worker only needs to insert the positioning pin 452 into the corresponding positioning groove 220. At this time, the positioning groove 220 prevents the glue-applying wheel 300 from rotating through the positioning pin 452 and the connecting frame 451. This can prevent the glue-applying wheel 300 from driving the rotating wheel 410 to rotate, so that the glue stops being dispensed, further reducing the probability of glue being wasted.

[0034] It should be noted that the glue storage tank 100, glue application wheel 300, driven pulley 420, belt 430 and driving pulley 440 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs, and will not be elaborated here.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
