Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating technology, specifically to a glue supply mechanism for a coating machine. Background Technology
[0002] In the coating industry, the coating machine is the core equipment, and its operational stability and coating quality are of paramount importance. The adhesive, as a key material in the coating process, directly affects the smooth operation of the coating process and the quality of the final product through accurate monitoring and effective control of its level.
[0003] Traditional adhesive level monitoring on coating machines often relies on manual operation. Workers need to periodically visit the coating machine to estimate the adhesive level by directly observing the markings on the adhesive storage container or using simple measuring tools. This method is not only labor-intensive and time-consuming, but also prone to significant errors due to human factors such as observation angle, lighting conditions, and individual judgment. Inaccurate level assessment can lead to insufficient adhesive causing coating interruptions, or excessive adhesive overflow resulting in waste and environmental pollution, severely impacting production efficiency and product quality. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a glue supply mechanism for a coating machine, which solves the problems mentioned in the background section.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a coating machine adhesive supply mechanism, comprising a coating machine, wherein the upper part of the coating machine is provided with a coating roller and an adhesive storage module, and the interior is provided with an adhesive pumping module; the adhesive storage module includes an adhesive box and a liquid level sensor installed thereon; the adhesive pumping module includes an adhesive storage tank and a metering pump, the metering pump being used to extract adhesive from the adhesive storage tank and pump it to the adhesive box.
[0006] Furthermore, the glue storage module has a glue inlet connector installed on the side of the glue container. The glue outlet of the glue inlet connector is connected to the inside of the glue container and is used to receive glue pumped by the metering pump.
[0007] Furthermore, the detection end of the liquid level sensor extends into the glue container to monitor the liquid level of the glue inside the container.
[0008] Furthermore, the upper part of the adhesive container is provided with an exhaust hole, which can quickly expel the air in the adhesive container during adhesive injection.
[0009] Furthermore, a drain valve is installed at the bottom of the adhesive container to drain the adhesive from the container; a viewing window is also installed on the side of the adhesive container, allowing workers to check the liquid level of the adhesive in the container.
[0010] Furthermore, the upper part of the glue storage tank of the glue pump module is connected to a glue delivery pipe and a pressure equalization pipe, respectively. The suction port of the glue delivery pipe extends to the bottom of the glue storage tank, and the glue outlet of the glue delivery pipe is connected to the glue inlet of the metering pump. A glue inlet pipe is connected between the glue outlet of the metering pump and the glue inlet connector of the glue storage module.
[0011] This invention provides an adhesive supply mechanism for a coating machine. Compared with the prior art, it has the following advantages:
[0012] Compared with existing methods of manually monitoring adhesive levels, this coating machine's adhesive monitoring mechanism uses a level sensor to monitor the adhesive level in the adhesive box in real time and precisely controls the start and stop of the metering pump based on the level value. This effectively avoids problems such as overflow due to untimely or inaccurate manual monitoring (or interruption of coating due to excessively high or low levels), significantly improving the stability and continuity of coating production and reducing material waste, equipment damage, and reduced production efficiency caused by production accidents.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-4This utility model provides a technical solution: a glue supply mechanism for a coating machine, mainly comprising a coating machine 1, a coating roller 2 (the coating machine 1 and coating roller 2 are existing structures and will not be described in detail here), a glue storage module 3, and a glue pumping module 4. The coating roller 2 is installed on the upper part of the coating machine 1 and is used for coating materials. The glue storage module 3 is also installed on the upper part of the coating machine 1 and is used to store glue and monitor the glue level. The glue pumping module 4 is installed inside the coating machine 1 and is responsible for pumping the glue from the glue storage tank 41 to the glue box 31 of the glue storage module 3.
[0020] The glue storage module 3 mainly consists of a glue container 31, a liquid level sensor 32, a glue inlet connector 33, a vent 34, a glue drain valve 35, and a viewing window 36. The glue container 31 serves as the storage container for the glue. A glue inlet connector 33 is installed on its side, and the outlet of the glue inlet connector 33 communicates with the interior of the glue container 31, allowing the glue to enter the glue container 31 through the glue inlet connector 33. A vent 34 is pre-installed at the top of the glue container 31. During the glue injection process, when the glue enters the glue container 31, the air inside the container can be quickly discharged through the vent 34, preventing air accumulation from affecting the storage and use of the glue. A glue drain valve 35 is installed at the bottom of the glue container 31. When it is necessary to replace the glue or clean the glue container 31, the glue can be drained by opening the glue drain valve 35. A viewing window 36 is also installed on the side of the adhesive container 31, allowing operators to visually monitor the adhesive level within the container. A level sensor 32 is installed on the upper part of the adhesive container 31, with its sensing end extending into the interior. The level sensor 32 monitors the adhesive level in the container 31 in real time and transmits the level signal to the control system (not shown in the figure) for appropriate operation based on the liquid level.
[0021] The glue pump module 4 mainly consists of a glue storage tank 41, a metering pump 42, a glue delivery pipe 43, a pressure equalization pipe 44, and a glue inlet pipe 45. The glue storage tank 41 is used to store a large amount of glue, and the glue delivery pipe 43 and the pressure equalization pipe 44 are connected to its upper part. The suction port of the glue delivery pipe 43 extends to the bottom of the glue storage tank 41 to ensure that the glue in the glue storage tank 41 can be fully extracted. The pressure equalization pipe 44 is connected to the inside of the glue storage tank 41. During the process of the metering pump 42 drawing glue, external air can enter the inside of the glue storage tank 41 through the pressure equalization pipe 44 to equalize the pressure inside the glue storage tank 41 and ensure the smooth extraction of glue. The metering pump 42 is installed in the coating machine 1, and its glue inlet is connected to the glue outlet of the glue delivery pipe 43. The glue outlet is connected to the glue inlet connector 33 through the glue inlet pipe 45. When the metering pump 42 is working, it can draw glue from the glue storage tank 41 through the glue delivery pipe 43, and pump the drawn glue to the glue inlet connector 33 through the glue inlet pipe 45, and then into the glue box 31.
[0022] When the device is in operation, the metering pump 42 draws adhesive from the storage tank 41 through the adhesive delivery pipe 43. During the drawing process, external air enters the storage tank 41 through the equalization pipe 44 to equalize the pressure inside the storage tank 41. The metering pump 42 pumps the drawn adhesive to the adhesive inlet connector 33 through the adhesive inlet pipe 45, and then into the adhesive box 31. As the adhesive supply process continues, the liquid level in the adhesive box 31 continuously increases. The liquid level sensor 32 also monitors the liquid level value in real time. When the liquid level value reaches the set value, the liquid level sensor 32 will control the metering pump 42 to stop pumping. It should be noted that the specific structure, working principle and control method of the metering pump 42 and the liquid level sensor 32 are all existing known technologies and will not be described in detail here.
