Description

Technical Field

[0001] This utility model relates to the field of medical packaging materials technology, and in particular to a solvent-free adhesive dosage control device for medical packaging composite films. Background Technology

[0002] Medical packaging composite film is a multi-layered functional composite film material designed to meet the safety requirements of sterilization, storage, transportation, and use of medical products. It is made by laminating substrates with different properties (such as plastics, aluminum foil, paper, etc.) through solvent-free lamination, dry lamination, and other processes. During the production process, the amount of solvent-free adhesive applied is affected by a variety of factors, including the cleanliness of the equipment roller surface, the hardness and pressure of the adhesive roller, the leveling properties of the adhesive, and the coating temperature. Therefore, it is necessary to precisely control the use of adhesive to ensure the quality of the medical packaging composite film.

[0003] However, during the production process, the glue delivery tube is prone to blockage during glue dispensing, leading to an imbalance in the ratio of A and B adhesives. If the dispensing volume of A and B adhesives differs too much, it may result in insufficient peeling force and failure of the glue to dry. Furthermore, during the dispensing process, air inside the glue tank is easily discharged, resulting in a large number of air bubbles in the mixed adhesive. This reduces the amount of glue applied subsequently and can easily cause changes in the ratio of A and B adhesives, affecting the quality of the adhesive.

[0004] Therefore, we provide a solvent-free adhesive dosage control device for medical packaging composite films to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a solvent-free adhesive dosage control device for medical packaging composite films, aiming to solve the problems mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A solvent-free adhesive dosage control device for medical packaging composite films includes a fixed base, an AB glue tank on the upper side of the fixed base, a dosage control component on the outer side of the AB glue tank, an alarm mounted on the outer side of the fixed base, a glue delivery pipe mounted on the right side of the AB glue tank, a feed pump mounted on the right side of the feed pipe, a pressure gauge mounted on the upper side of the feed pump, a mounting frame mounted on the right side of the fixed base, an exhaust box mounted on the upper side of the mounting frame, a material tank assembly mounted on the right side of the mounting frame, the material tank assembly including a storage tank on the right side of the mounting frame, and a mixing tank mounted inside the storage tank.

[0007] The pressure gauge's probe is located inside the glue delivery tube, and the alarm is electrically connected to the pressure gauge.

[0008] A flow sensor is installed on the right side of the feed pump, and the alarm is electrically connected to the flow sensor.

[0009] The exhaust box is connected to the glue delivery pipe by a pipe, and the exhaust box has a hollow structure. The exhaust box is connected to the storage tank through a pipe.

[0010] An exhaust valve is installed on the outside of the exhaust box. The exhaust valve is connected to the top of the exhaust box through a pipe. The exhaust valve is a KP type composite air valve.

[0011] A level gauge is installed on the right side of the exhaust valve. The level gauge is connected to the exhaust box. The level gauge is a float-type level measuring instrument.

[0012] A discharge valve is installed on the lower side of the mixing tank, and a metering pump is installed on the lower side of the discharge valve. The outer pipe of the metering pump is connected to a glue tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting up a glue quantity control component, the pressure inside the glue delivery pipe is monitored in real time by a pressure gauge. When the glue delivery pipe is blocked, the pressure inside the glue delivery pipe will continue to rise due to the continuous operation of the feed pump. When the pressure exceeds the preset pressure threshold, the signal is transmitted to the alarm, which will issue an alarm to remind the operator that the equipment has malfunctioned. At the same time, when A and B glues pass through the exhaust box and accumulate, the air inside A and B glues will naturally rise to the pipe on the upper side of the exhaust box, and the air can be drawn out and discharged through the exhaust valve to avoid a large number of air bubbles inside A and B glues, which would affect the quality of the adhesive and the coating effect.

[0014] 2. By setting up a material hopper assembly, the amount of adhesive delivered can be precisely controlled by a metering pump during transport, keeping it within a set threshold. This avoids imbalances in adhesive quantity caused by excessive or insufficient dispensing, which could affect the normal operation of the overall work. Attached Figure Description

[0017] Please see Figure 1-4 As shown, a solvent-free adhesive for medical packaging composite film includes a fixed base 1, an AB glue tank 2 on the upper side of the fixed base 1, an adhesive quantity control component 3 on the outer side of the AB glue tank 2, an alarm 301 installed on the outer side of the fixed base 1, a glue delivery pipe 302 installed on the right side of the AB glue tank 2, a feed pump 303 on the right side of the feed pump 302, a pressure gauge 304 on the upper side of the feed pump 303, a mounting frame 306 on the right side of the fixed base 1, an exhaust box 307 on the upper side of the mounting frame 306, a material tank assembly 4 on the right side of the mounting frame 306, a storage tank 401 on the right side of the mounting frame 306, and a mixing tank 402 on the inner side of the storage tank 401.

[0018] The detection probe of the pressure gauge 304 is installed inside the glue delivery tube 302. The alarm 301 is connected to the pressure gauge 304 by telecommunications. The pressure gauge 304 monitors the pressure in the glue delivery tube 302 in real time. When the glue delivery tube 302 is blocked, the pressure in the glue delivery tube 302 will continue to rise due to the continuous operation of the feed pump 303. When the pressure exceeds the preset pressure threshold, the signal is transmitted to the alarm 301, which will issue an alarm to remind the operator that the equipment has malfunctioned.

[0019] A flow sensor 305 is installed on the right side of the feed pump 303. The alarm 301 is connected to the flow sensor 305. The flow sensor 305 detects the amount of glue flowing out in real time. When the amount of glue detected by the flow sensor 305 changes, the alarm 301 will issue an audible and visual alarm, which can promptly notify the staff to stop the machine for maintenance and avoid adhesive failure caused by the ratio deviation of glue output.

[0020] The exhaust box 307 is connected to the glue delivery pipe 302 by a pipe, and the exhaust box 307 has a hollow structure. The exhaust box 307 is connected to the storage tank 401 through a pipe. When A and B glues pass through the exhaust box 307, they will accumulate inside the exhaust box 307 until there is no air before being output to the subsequent glue delivery pipe 302, so as to avoid a large amount of air inside A and B glues affecting the quality of the adhesive.

[0021] An exhaust valve 308 is installed on the outside of the exhaust box 307. The exhaust valve 308 is connected to the top of the exhaust box 307 through a pipe. The exhaust valve 308 is a KP type composite air valve. When A and B adhesives pass through the inside of the exhaust box 307 and accumulate, the air inside A and B adhesives will naturally rise to the inside of the pipe on the upper side of the exhaust box 307. The air can be drawn out and discharged through the exhaust valve 308 to avoid a large number of air bubbles inside A and B adhesives, which would affect the quality of the adhesive and the coating effect.

[0022] A level gauge 309 is installed on the right side of the exhaust valve 308. The level gauge 309 is connected to the exhaust box 307. The level gauge 309 is a float-type level measuring instrument. The level gauge 309 can reflect the level of adhesive inside the exhaust box 307. By observing whether the real-time height of the level gauge 309 has reached its maximum, when the height of the level gauge 309 reaches its maximum, it means that all the air inside the exhaust box 307 has been exhausted. This helps the operator to judge whether all the air inside the A and B adhesives in the exhaust box 307 has been exhausted, so as to facilitate the normal operation of subsequent work.

[0023] A discharge valve 403 is installed on the lower side of the mixing tank 402, and a metering pump 404 is installed on the lower side of the discharge valve 403. The outer pipe of the metering pump 404 is connected to the glue tank 405. When the adhesive is transported, the metering pump 404 precisely controls the amount of delivery to keep it within the set threshold. This can avoid the subsequent glue quantity imbalance caused by too much or too little glue, which would affect the normal operation of the overall work.

[0024] When the overall operation begins, the feed pump 303 discharges the A and B adhesives from the AB adhesive tank 2 and supplies them to the adhesive delivery pipe 302. Simultaneously, the pressure gauge 304 monitors the inside of the adhesive delivery pipe 302 to detect any blockages. If a blockage occurs, the alarm 301 emits an audible and visual alarm to alert the operator for adjustment. The flow sensor 305 monitors the amount of adhesive flowing out in real time. When the flow sensor detects a change in the amount of adhesive, the alarm 301 emits an audible and visual alarm, promptly notifying the operator to stop the machine for maintenance. When the A and B adhesives pass through the exhaust box 307, they accumulate inside. The air inside the A and B adhesives naturally rises to the pipe above the exhaust box 307 and is then discharged through the exhaust system. The air valve 308 can extract and discharge air, preventing a large number of air bubbles inside the A and B adhesives. At the same time, the liquid level gauge 309 can reflect the adhesive level inside the exhaust box 307. By observing whether the real-time height of the liquid level gauge 309 has reached its maximum, it means that all the air inside the exhaust box 307 has been discharged. This helps the operator determine whether all the air inside the A and B adhesives in the exhaust box 307 has been removed. When the adhesive is transported, the metering pump 404 precisely controls the amount of adhesive delivered, keeping it within the set threshold. This avoids subsequent adhesive quantity imbalances caused by too much or too little adhesive being dispensed, which would affect the normal operation of the overall work. This completes the process of using a solvent-free adhesive quantity control device for medical packaging composite films.
