Description

Technical Field

[0001] This utility model relates to the field of adhesive coating equipment technology, and more specifically, to an adhesive coating equipment for the production of dressing patches. Background Technology

[0002] In the production process of dressings, adhesive is applied to the surface of the dressing substrate to ensure that the dressing does not fall off during use. The quality of this application directly affects the performance and effectiveness of the dressing. Adhesive application is generally performed using an adhesive application device, such as the adhesive application device for dressing production described in patent publication number CN214812256U. This device includes: an adhesive application mechanism for applying an adhesive layer to the surface of the dressing; a drying mechanism for drying the coated dressing; a winding mechanism for winding the dried dressing; and a driving mechanism for driving the dressing through the adhesive application mechanism, drying mechanism, and winding mechanism sequentially to complete the adhesive application. The driving mechanism drives the dressing through the adhesive application mechanism and drying mechanism sequentially to apply adhesive and dry the dressing before the winding mechanism winds it up.

[0003] While the aforementioned adhesive applicator can apply adhesive to the material surface, in actual application, the adhesive is continuously consumed during the process. If not replenished in time, insufficient adhesive supply at the application point will lead to uneven adhesive distribution on the dressing, resulting in localized areas of insufficient or no adhesive. This affects the adhesion and bonding strength between the dressing and the skin, reducing product quality. Conversely, excessive adhesive replenishment can cause the adhesive to dry and set prematurely due to external environmental factors such as temperature, humidity, and air circulation. For example, in high-temperature, dry production environments, large quantities of stored adhesive can quickly dry and form a hard shell, wasting adhesive and potentially clogging the applicator head, disrupting the normal operation of the applicator. Utility Model Content

[0004] The main purpose of this invention is to provide a gluing device for the production of dressing patches, which can effectively solve the problem that the above-mentioned gluing device cannot maintain the glue level, resulting in a decrease in the gluing effect.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A gluing device for producing dressing patches includes a placement table with conveyor belts on both sides. A fixed bracket is fixedly installed in the middle of the placement table, and a PLC control box is fixedly installed at the bottom of the fixed bracket. A gluing component for applying glue is provided in the middle of the fixed bracket, and a replenishing component for replenishing glue is fixedly installed at the upper end of the fixed bracket. The conveyor belts are connected to the PLC control box via signals.

[0007] Preferably, the glue application assembly includes a conveying pressure roller, a first glue application roller, and a second glue application roller. The conveying pressure roller is rotatably mounted in the middle of the fixed support, and the upper end of the conveying pressure roller is parallel to the upper end of the conveyor belt. The first glue application roller and the second glue application roller are rotatably mounted on both sides of the middle of the fixed support, and the first glue application roller is perpendicularly aligned with the conveying pressure roller.

[0008] Preferably, two extension platforms are fixedly installed on the outer side of the fixed bracket. A first motor and a second motor are fixedly installed on the upper end of the two extension platforms, respectively. The output end of the first motor is fixedly connected to the conveying pressure roller, and the output end of the second motor is fixedly connected to the second glue coating roller. The first motor and the second motor are connected to the PLC control box for signal connection.

[0009] Preferably, a transmission gear is fixedly installed at one end of both the first and second coating rollers, and the two transmission gears mesh with each other.

[0010] Preferably, the supplementary component includes a storage box, which is fixedly installed on the upper end of a fixed bracket. The storage box has an adhesive storage tank inside, and an adhesive outlet is provided at the lower end of the adhesive storage tank. An electric heating tube assembly for heating the adhesive is fixedly installed inside the storage box. A cover plate is provided at the upper end of the storage box, and auxiliary scrapers are provided on both sides of the adhesive outlet.

[0011] Preferably, a glue storage cavity is provided between the upper ends of the first and second glue application rollers, a transparent window is provided on one side of the fixed bracket, an ultrasonic liquid level sensor is fixedly installed on one side of the transparent window, the ultrasonic liquid level sensor is located above the glue storage cavity and a baffle is provided on the upper end of the ultrasonic liquid level sensor, and the ultrasonic liquid level sensor is connected to the PLC control box for signal transmission.

[0012] Preferably, a control motor is fixedly installed on one side of the storage box, the output end of the control motor extends to the dispensing port and is fixedly installed with a rotating shaft, one half of the rotating shaft is provided with a number of material feeding blades, and the other half of the rotating shaft is provided with a high-temperature resistant sealing gasket.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) The dressing substrate can be transported to the gluing assembly by the conveyor belt and discharged after the gluing is completed. When the substrate enters the gluing assembly, the relative rotation between the first gluing roller and the second gluing roller is achieved by starting the second motor and cooperating with two transmission gears. During the rotation, the glue inside the glue storage cavity can be distributed to the first gluing roller. The first motor is started to drive the conveying pressure roller to rotate. At this time, the substrate will be located between the conveying pressure roller and the first gluing roller, thereby realizing the gluing operation on the surface of the substrate.

[0015] (2) The ultrasonic liquid level sensor can monitor the liquid level inside the lower glue storage cavity in real time. When the liquid level is too low, the ultrasonic liquid level sensor uses the PLC control box to control the motor to rotate. When the motor rotates, several material-pulling plates are set on one half of the rotating shaft, which will cause the glue inside the glue storage tank to be discharged downward until the liquid level reaches the predetermined position. When closing the glue outlet, an encoder can be installed in the control motor to ensure that the other half of the rotating shaft blocks the glue outlet when closing it. The high-temperature resistant sealing gasket can prevent glue leakage, and the heat resistance temperature of the high-temperature resistant sealing gasket is higher than the temperature of the heated glue. With the above structure, the glue application will not experience a decrease or unevenness in the glue application effect due to untimely glue replenishment during continuous glue application, nor will it experience premature drying and setting of the glue due to excessive glue storage. This ensures the stability and glue application quality of the application during continuous glue application. Attached Figure Description

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0024] like Figures 1 to 6 As shown, a gluing device for producing dressing patches includes a placement table 1, conveyor belts 2 on both sides of the placement table 1, a fixed bracket 4 fixedly installed in the middle of the placement table 1, a PLC control box 6 fixedly installed at the bottom of the fixed bracket 4, a gluing component 3 for applying glue in the middle of the fixed bracket 4, and a replenishing component 5 for replenishing glue fixedly installed at the upper end of the fixed bracket 4. The conveyor belts 2 are connected to the PLC control box 6 via signal. The PLC control box 6 can control the start and stop of the conveyor belts 2, the electric heating tube assembly 503, the first motor 306, the second motor 307, and the control motor 504. In conjunction with the ultrasonic liquid level sensor 506, the start and stop of the control motor 504 can be controlled separately with additional conditions to ensure sufficient glue level in the glue storage cavity 308. An encoder can be installed in the above equipment as needed, and the PLC control can realize the synchronous rotation of the first motor 306 and the second motor 307 to ensure the stability of the substrate when being coated with glue. The rotating structure of this application is all low-speed rotation to avoid glue splashing due to inertia caused by high-speed rotation.

[0025] In this embodiment, the glue application assembly 3 includes a conveying pressure roller 301, a first glue application roller 302, and a second glue application roller 303. The conveying pressure roller 301 is rotatably mounted in the middle of the fixed bracket 4, and the upper end of the conveying pressure roller 301 is parallel to the upper end of the conveyor belt 2. The first glue application roller 302 and the second glue application roller 303 are respectively rotatably mounted on both sides of the middle of the fixed bracket 4, and the first glue application roller 302 is vertically aligned with the conveying pressure roller 301.

[0026] Two extension platforms 305 are fixedly installed on the outside of the fixed bracket 4. A first motor 306 and a second motor 307 are fixedly installed on the upper end of the two extension platforms 305 respectively. The output end of the first motor 306 is fixedly connected to the conveying pressure roller 301, and the output end of the second motor 307 is fixedly connected to the second glue coating roller 303. The first motor 306 and the second motor 307 are connected to the PLC control box 6 for signal connection.

[0027] A transmission gear 304 is fixedly installed at one end of both the first coating roller 302 and the second coating roller 303, and the two transmission gears 304 mesh with each other.

[0028] The dressing substrate can be transported to the gluing assembly 3 by the conveyor belt 2 and discharged after gluing is completed. When the substrate enters the gluing assembly 3, the relative rotation between the first gluing roller 302 and the second gluing roller 303 is achieved by starting the second motor 307 and cooperating with the two transmission gears 304. During the rotation, the glue inside the glue storage cavity 308 can be distributed to the first gluing roller 302. The first motor 306 is started to drive the conveying pressure roller 301 to rotate. At this time, the substrate will be located between the conveying pressure roller 301 and the first gluing roller 302, thereby realizing the gluing operation on the surface of the substrate.

[0029] In this embodiment, the supplementary component 5 includes a storage box 501, which is fixedly installed on the upper end of the fixed bracket 4. The storage box 501 has an adhesive storage tank 5011 inside, and an adhesive outlet 5012 at the lower end of the adhesive storage tank 5011. An electric heating element assembly 503 for heating the adhesive is fixedly installed inside the storage box 501. A cover plate 502 is provided at the upper end of the storage box 501, and auxiliary scrapers 5013 are provided on both sides of the adhesive outlet 5012. The electric heating element assembly 503 prevents the adhesive inside the adhesive storage tank 5011 from drying and solidifying, and the auxiliary scrapers 5013 can scrape off any residual adhesive on the outer surface of the high-temperature resistant sealing gasket 5043, preventing adhesive residue from remaining on the surface of the high-temperature resistant sealing gasket 5043.

[0030] A glue storage cavity 308 is provided between the upper ends of the first glue-applying roller 302 and the second glue-applying roller 303. A transparent window 505 is provided on one side of the fixed bracket 4. An ultrasonic liquid level sensor 506 is fixedly installed on one side of the transparent window 505. The ultrasonic liquid level sensor 506 is located above the glue storage cavity 308 and a shielding plate for blocking glue is provided on the upper end of the ultrasonic liquid level sensor 506. The ultrasonic liquid level sensor 506 is connected to the PLC control box 6 for signal connection.

[0031] In this embodiment, a control motor 504 is fixedly installed on one side of the storage box 501. The output end of the control motor 504 extends to the dispensing port 5012 and is fixedly installed with a rotating shaft 5041. Half of the rotating shaft 5041 is provided with a plurality of material feeding plates 5042, and the other half of the rotating shaft 5041 is provided with a high-temperature resistant sealing gasket 5043.

[0032] The ultrasonic level sensor 506 can monitor the liquid level inside the lower glue storage cavity 308 in real time. When the liquid level is too low, the ultrasonic level sensor 506 uses the PLC control box 6 to control the rotation of the control motor 504. When the control motor 504 rotates, several material-pulling blades 5042 are set on one half of the rotating shaft 5041, which will cause the glue inside the glue storage tank 5011 to be discharged downwards until the liquid level reaches the predetermined position. Furthermore, when closing the glue outlet 5012, an encoder installed in the control motor 504 can be used to ensure that the rotation is synchronized when the glue outlet 5012 is closed. The other half of the shaft 5041 blocks and closes the glue outlet 5012. The high-temperature resistant sealing gasket 5043 is provided to prevent glue leakage. The heat resistance temperature of the high-temperature resistant sealing gasket 5043 is higher than that of the heated glue. The above structure ensures that the glue application effect will not decrease or become uneven due to untimely glue replenishment during continuous glue application, and that the glue will not dry and set prematurely due to excessive glue storage. This ensures the stability and glue application quality of the application during continuous glue application.

[0033] The working principle of this adhesive coating equipment for dressing production:

[0034] In use, the dressing is first conveyed to the adhesive application assembly 3 by the conveyor belt 2. When the substrate enters the adhesive application assembly 3, the second motor 307 is started and two transmission gears 304 are used to realize the relative rotation between the first adhesive application roller 302 and the second adhesive application roller 303. During the rotation, the glue inside the glue storage cavity 308 can be distributed to the first adhesive application roller 302. The first motor 306 is started to drive the conveyor roller 301 to rotate. At this time, the substrate will be located between the conveyor roller 301 and the first adhesive application roller 302, thereby realizing the adhesive application operation on the surface of the substrate. After that, the glued material will be discharged from the other side of the conveyor belt 2.

[0035] When the glue level inside the glue storage cavity 308 is too low, the ultrasonic level sensor 506 can monitor the glue level inside the lower glue storage cavity 308 in real time. When the level is too low, the ultrasonic level sensor 506 uses the PLC control box 6 to control the rotation of the control motor 504. When the control motor 504 rotates, the glue inside the glue storage tank 5011 will be discharged downwards by using several material-pulling plates 5042 set on half of the rotating shaft 5041 until the liquid level reaches the predetermined position, so as to realize automatic glue replenishment and avoid the glue coating effect from decreasing.

[0036] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
