Description

Technical Field

[0001] This utility model relates to the technical field of adhesive film paper impregnation production equipment, and in particular to a constant temperature structure for the glue tank in adhesive film paper impregnation production. Background Technology

[0002] In the early stages of glue film paper impregnation production, methods ranging from lacking temperature control of the glue bath to manually controlling the glue temperature at set times were all difficult to use precisely, thus affecting the performance indicators of the glue film paper during the impregnation process. These methods also resulted in energy waste due to the lack of temperature control: the glue bath temperature changed with the ambient temperature; timed temperature control resulted in large temperature differences in the glue, which easily caused glue deterioration; and manual control increased the labor intensity of workers. Summary of the Invention

[0003] The purpose of this invention is to provide a constant temperature structure for the glue tank in the production of adhesive film paper impregnation, with an automatic constant temperature adjustment mode, so that the temperature of the glue in the glue tank can be quickly stabilized within the required temperature range, thereby improving product quality and thus effectively solving the above-mentioned technical problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A constant-temperature structure for a glue tank in the production of adhesive film paper impregnation includes a glue tank mounted on a frame. The bottom of the glue tank extends downward to form a closed cavity. An inlet and an outlet are provided on the corresponding side walls of the cavity, connecting to the cavity. The inlet and outlet are connected together to a heating and cooling integrated device to form a liquid circulation system. A solenoid valve is installed on the pipe connected to the inlet, controlling the opening and closing of the inlet. The heating and cooling integrated device is used to heat or cool the liquid to obtain a working liquid. The working liquid is introduced into the cavity through the inlet. The working liquid in the cavity heats or cools the glue tank by contacting the bottom of the glue tank, causing the glue in the tank to rise or fall to the required temperature. A temperature sensor is inserted into the glue tank to monitor the glue temperature in real time, and a controller on the frame controls the on / off state of the solenoid valve based on the monitored glue temperature.

[0006] The above solution further includes an acquisition module for acquiring the glue temperature monitored by a temperature sensor, a comparison module for comparing the monitored glue temperature with a set glue temperature, and a control module for controlling the on / off state of the solenoid valve based on the comparison result; the set glue temperature is a temperature value input by the worker according to production needs.

[0007] The above scheme is further described in that the inlet and outlet are located on the same side of the cavity, and multiple partitions are arranged side by side inside the cavity to divide the cavity into a serpentine flow channel. The inlet and outlet are respectively connected to the beginning and end ports of the serpentine flow channel.

[0008] This invention constructs a closed cavity extending downwards from the bottom of the glue tank. A working fluid is introduced into the cavity, which heats or cools the glue tank, raising or lowering the glue temperature to the required level. A temperature sensor is inserted into the glue tank to monitor the glue temperature in real time, and a controller on the frame controls the on / off state of a solenoid valve based on the monitored glue temperature. Workers input the temperature values ​​provided by the process department into the controller to activate the fully automatic constant temperature control mode. The working fluid in the cavity heats or cools the glue tank by contacting its bottom, quickly stabilizing the glue temperature within the required range. This solves the shortcomings of existing manual timed control of glue temperature, promotes production, and effectively improves product quality.

[0009] This utility model has a simple structure, low investment cost, is suitable for the development of modern intelligent work, and promotes the production and use of adhesive film paper. Attached Figure Description

[0014] The following will further explain the concept, specific structure and technical effects of this utility model in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of this utility model.

[0015] It should be noted that in the description of this utility model, the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0016] See Figure 1 , 2Figures 3 and 4 show schematic diagrams of a preferred embodiment of this utility model. This utility model relates to a constant-temperature structure for a glue tank used in the production of adhesive film paper impregnation. It includes a glue tank 2 mounted on a frame 1. The bottom of the glue tank 2 extends downwards to form a closed cavity 3. The glue tank 2 and cavity 3 are manufactured using sheet metal stamping and welding, making them an integral unit, which facilitates subsequent heat transfer. The corresponding sidewalls of the cavity 3 are provided with an inlet 31 and an outlet 32 ​​connecting to the cavity 3. The inlet 31 and outlet 32 ​​are connected together to a heating and cooling integrated device 4, forming a liquid circulation system. A solenoid valve 5 is installed on the pipe connected to the inlet 31, controlling the opening and closing of the inlet 31. The heating and cooling integrated device 4 is used to heat or cool the liquid to obtain a working liquid. Preferably, the heating and cooling integrated device 4 is a heat pump unit, which is energy-saving and environmentally friendly, and the liquid is water. The working liquid is introduced into the cavity 3 through the inlet 31. The working liquid in the cavity 3 heats or cools the glue tank 2 by contacting the bottom of the glue tank, so that the glue in the glue tank 2 rises or falls to the required temperature. A temperature sensor 6 is inserted into the glue tank 2 to monitor the glue temperature in real time, and a controller 7 is set on the frame 1 to control the opening and closing of the solenoid valve 5 according to the monitored glue temperature.

[0017] In use, temperature sensor 6 is connected to controller 7 via wires. Controller 7 includes an acquisition module for obtaining the glue temperature monitored by the temperature sensor, a comparison module for comparing the monitored glue temperature with a set glue temperature, and a control module for controlling the opening and closing of solenoid valve 5 based on the comparison result. The set glue temperature is a value input by the worker according to production needs. After receiving the temperature value signal input by the worker, the controller compares the set glue temperature value with the actual monitored glue temperature feedback value and automatically controls the opening and closing of solenoid valve 5 in the pipeline to achieve a constant glue temperature. For example, in cooling mode, if the set glue temperature is 25℃ and the actual monitored glue temperature feedback value is 30℃, the controller will give a solenoid valve opening signal. Cold water will circulate between the cavity 3 and the integrated heating and cooling device 4. When the actual temperature approaches 25℃, the solenoid valve will slowly adjust; when the actual temperature reaches 25℃, the solenoid valve will close directly. Conversely, the heating mode works similarly.

[0018] In this embodiment, the inlet 31 and outlet 32 ​​are located on the same side of the cavity 3. Multiple partitions 33 are arranged side-by-side inside the cavity 3, dividing the interior of the cavity 3 into a serpentine flow channel 34. The inlet 31 and outlet 32 ​​are respectively connected to the beginning and end ports of the serpentine flow channel 34. This structure effectively guides the water flow, increases the flow path, improves the heat exchange effect, and allows the glue temperature in the glue tank to quickly stabilize within the required temperature range.

[0019] Figure 4As shown, in use, this utility model is integrated into the impregnation production line and located between the unwinder 100 and the baking oven 200. The raw paper is unwound by the unwinder 100 and guided by the corresponding guide rollers into the glue tank 2 on the frame 1. After impregnation, the raw paper passes through the corresponding glue control rollers and is output. The glue tank 2 extends along the direction of the raw paper movement. Similarly, the cavity 3 also extends along the direction of the raw paper movement at the bottom of the glue tank 2. The liquid inlet 31 and the liquid outlet 32 ​​are located on the side of the cavity 3 near the output of the raw paper after impregnation. The partition 33 is also arranged sideways along the direction of the raw paper movement inside the cavity 3 and has corresponding connecting ports so as to divide the interior of the cavity 3 into a serpentine flow channel 34. The structure is simple and helps to quickly stabilize the glue temperature in the glue tank within the required temperature range.

[0020] This invention features a simple structure and low investment cost. A closed cavity extends downwards from the bottom of the glue tank, through which a working fluid is introduced. This working fluid heats or cools the glue tank, raising or lowering the glue temperature to the required level. A temperature sensor is inserted into the glue tank to monitor the glue temperature in real time, and a controller on the frame controls the on / off state of a solenoid valve based on the monitored glue temperature. Workers input the temperature values ​​provided by the process department into the controller, activating a fully automatic constant temperature control mode. The working fluid in the cavity heats or cools the glue tank by contacting its bottom, quickly stabilizing the glue temperature within the required range. This overcomes the shortcomings of existing manual timed control of glue temperature, promotes production, effectively improves product quality, and is suitable for modern intelligent manufacturing processes.

This is only to illustrate the technical concept and features of the present invention, and its purpose is to enable those skilled in the art to understand the content of the present invention and implement it. It should not be used to limit the scope of protection of the present invention.
