Abstract
Description
Technical Field
[0001] This utility model relates to the field of adhesive processing technology, and in particular to a heating device for adhesive preparation. Background Technology
[0002] Heating devices for adhesive preparation are core equipment specifically designed to provide controllable heat during the production of adhesives (such as hot melt adhesives, water-based adhesives, solvent-based adhesives, etc.). Their design must be adapted to the characteristics of adhesive raw materials (such as resin melting, exothermic / endothermic chemical reactions, solvent evaporation, etc.) and process requirements (such as isothermal reaction, gradient heating, and prevention of local overheating, etc.).
[0003] Existing heating devices generally employ a single heating structure, such as a heating medium or an electrothermal structure, when heating adhesive preparation devices. However, this single heating structure wastes a significant amount of time when heating adhesive preparation devices, thus affecting the efficiency of adhesive preparation. Utility Model Content
[0004] To address the aforementioned problems, this invention proposes a heating device for adhesive preparation to more accurately resolve these issues.
[0005] This utility model is achieved through the following technical solution:
[0006] This utility model proposes a heating device for adhesive preparation, including a preparation barrel, a heating component disposed inside the preparation barrel, and a sealing cover disposed on the top of the preparation barrel for sealing the preparation barrel. The sealing cover is provided with a stirring component for stirring the raw materials inside the preparation barrel. The preparation barrel includes an outer shell and an inner partition disposed inside the outer shell. A heating chamber is disposed between the outer shell and the inner partition. An annular partition is disposed inside the heating chamber, and the annular partition divides the heating chamber equally, forming a first heating chamber and a second heating chamber. The heating component includes an electric heating tube that is attached to the outer wall of the inner partition and is spirally arranged, and a plurality of heat dissipation teeth disposed on the outer wall of the inner partition and located between the electric heating tubes. One end of the heat dissipation teeth passes through the annular partition and is connected to the inner wall of the outer shell. A medium output port communicating with the second heating chamber is opened on one side of the top of the preparation barrel, and a medium injection port communicating with the second heating chamber is opened on the other side of the bottom of the preparation barrel.
[0007] Furthermore, both ends of the electric heating tube pass through the preparation tank and are connected to an external control terminal via wires.
[0008] Furthermore, the inner wall of this invention is provided with a plurality of temperature sensors, which are connected to an external control terminal.
[0009] Furthermore, the stirring assembly includes a motor disposed on the top of the sealing cover and a stirring rod disposed on the bottom of the sealing cover and connected to the output end of the motor, wherein a plurality of stirring paddles are disposed on the circumferential direction of the stirring rod.
[0010] Furthermore, the present invention provides a support frame on the circumference of the bottom of the preparation barrel, a discharge pipe in the middle of the bottom of the preparation barrel, and a valve on the discharge pipe.
[0011] The beneficial effects of this utility model are:
[0012] The electric heating element generates heat when powered on, which is conducted to the preparation tank through the inner partition, thus raising the temperature inside the tank. The second heating chamber, heat dissipation teeth, medium injection port, and medium delivery port work together to inject the heating medium into the second heating chamber. The heat from the heating medium exchanges heat with the inner partition through the heat dissipation teeth, raising the temperature of the inner partition. This heating method, combined with the electric heating element, can quickly raise the temperature inside the preparation tank. Furthermore, the dual heating structures not only allow operators to choose different heating structures according to the environment, but also allow the other heating structure to be used if one heating structure fails, further extending the service life of the equipment.
[0013] The second heating chamber, heat dissipation teeth, medium injection port, and medium delivery port are designed to allow the heating medium to exchange heat with the inner partition plate through the heat dissipation teeth when the inner partition plate temperature is too high, thereby reducing the temperature of the inner partition plate.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, of the embodiments of this utility model. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0020] Example
[0021] refer to Figure 1-4 A heating device for preparing an adhesive includes a preparation tank 1, a heating component 2 disposed inside the preparation tank 1, and a sealing cover 3 disposed on the top of the preparation tank 1 for sealing the preparation tank 1. A stirring component 4 for stirring the raw materials inside the preparation tank 1 is disposed on the sealing cover 3. The preparation tank 1 includes an outer shell 11 and an inner partition 12 disposed within the outer shell 11. A heating chamber 13 is disposed between the outer shell 11 and the inner partition 12. An annular partition 14 is disposed within the heating chamber 13, and the annular partition 14 evenly divides the heating chamber 13 and forms a heating chamber 13. The first heating chamber 15 and the second heating chamber 16 are formed. The heating component 2 includes an electric heating tube 21 that is attached to the outer wall of the inner partition 12 and is arranged in a spiral, and a plurality of heat dissipation teeth 22 that are disposed on the outer wall of the inner partition 12 and located between the electric heating tubes 21. One end of the heat dissipation teeth 22 passes through the annular partition 14 and is connected to the inner wall of the outer shell 11. A medium output port 23 communicating with the second heating chamber 16 is opened on one side of the top of the preparation barrel 1, and a medium injection port 24 communicating with the second heating chamber 16 is opened on the other side of the bottom of the preparation barrel 1.
[0022] The preparation tank 1 is designed to store the raw materials to be prepared, while the stirring component 4 is designed to stir the raw materials in the preparation tank 1. The heating component 2 is designed to heat the raw materials in the preparation tank 1 and works in conjunction with the stirring component 4 to increase the rate of heat diffusion, thereby ensuring the adhesive preparation process.
[0023] The electric heating tube 21 generates heat when powered on, and the heat is conducted to the preparation tank 1 through the inner partition 12, thus heating the preparation tank 1. The second heating chamber 16, heat dissipation teeth 22, medium injection port 24, and medium delivery port work together to inject the heating medium into the second heating chamber 16. The heat of the heating medium exchanges heat with the inner partition 12 through the heat dissipation teeth 22, thus heating the inner partition 12. This heating method, in conjunction with the electric heating tube 21, can quickly heat the preparation tank 1. At the same time, the setting of two heating structures not only makes it convenient for the staff to select different heating structures according to the environment, but also allows the equipment to be heated after one heating structure is used, further increasing the service life of the equipment itself.
[0024] The second heating chamber 16, heat dissipation teeth 22, medium injection port 24 and medium delivery port are designed so that when the temperature of the inner partition 12 is too high, the heating medium can exchange heat with the inner partition 12 through the heat dissipation teeth 22, thereby reducing the temperature of the inner partition 12.
[0025] In this embodiment, the heating medium includes water or heat transfer oil, etc.
[0026] In this embodiment, the inner partition 12 is made of a metal thermally conductive material, such as aluminum alloy;
[0027] In this embodiment, optionally, the annular partition 14 can be made of metal heat insulation material, such as coating the surface of the annular partition 14 with a heat insulation coating to prevent the internal temperatures of the first heating chamber 15 and the second heating chamber 16 from affecting each other.
[0028] In this embodiment, it should be noted that both the medium injection port 24 and the medium output port 23 are connected to the external circulating pump body through pipes, and the circulating pump body is connected to the external heating thermostat circulator, thereby ensuring the operation of the thermostat medium input and the heating medium output heating work.
[0029] In this embodiment, both ends of the electric heating tube 21 pass through the preparation barrel 1 and are connected to an external control terminal via wires.
[0030] In this embodiment, a plurality of temperature sensors 5 are provided on the inner wall, and the temperature sensors are connected to an external control terminal;
[0031] Temperature sensor 5 can detect the temperature inside preparation tank 1 in real time and transmit the detected data to an external control terminal, which can control the working status of the electric heating tube based on the received data.
[0032] It should be noted that the temperature control technology for electric heating elements is an existing mature structure, such as a closed-loop feedback control system. However, the control system and control terminal structure are not within the scope of protection of this application. Therefore, this application will not provide a detailed description of the control technology for the electric heating element, temperature sensor 5, and heating medium.
[0033] like Figure 4 As shown, the stirring assembly 4 includes a motor 41 disposed on the top of the sealing cover 3 and a stirring rod 42 disposed on the bottom of the sealing cover 3 and connected to the output end of the motor 41. Several stirring paddles 43 are disposed on the circumference of the stirring rod 42.
[0034] The motor 41 enables the stirring rod 42 and the stirring paddle 43 to rotate, and the rotating stirring rod 42 and the stirring paddle 43 will complete the stirring and mixing of the raw materials in the preparation tank 1.
[0035] In this embodiment, a support 19 is provided around the bottom of the preparation barrel 1, and a discharge pipe 17 is provided in the middle of the bottom end of the preparation barrel 1. A valve 18 is provided on the discharge pipe 17.
[0036] The discharge pipe 17 is designed to output the processed raw materials, while the valve 18 is designed to control the connection status of the discharge pipe 17.
[0037] Working principle:
[0038] First, the staff injects the required raw materials into the preparation tank 1. After the raw materials are injected, the staff installs the sealing cap 3 on the top of the preparation tank 1. At the same time, the drive motor drives the stirring rod 42 and the stirring paddle 43 to rotate. The rotating stirring rod 42 and the stirring paddle 43 will complete the stirring and mixing work of the raw materials in the preparation tank 1. Before the stirring rod 42 and the stirring paddle 43 start stirring, the electric heating tube 21 can generate heat when it is powered on. The heat will be conducted to the inside of the preparation tank 1 through the inner partition 12, and complete the heating work of the preparation tank 1. The second heating chamber 16, the heat dissipation teeth 22, the medium injection port 24 and the medium delivery port cooperate to inject the heating medium into the second heating chamber 16. Heat is exchanged with the inner partition 12 through the heat dissipation teeth 22, thus raising the temperature of the inner partition 12. This heating method, in conjunction with the electric heating tube 21, can quickly raise the temperature inside the preparation tank 1. Furthermore, the dual heating structures allow operators to select different structures based on the environment, and also enable the use of the other heating structure if one fails, further extending the equipment's lifespan. Additionally, the second heating chamber 16, heat dissipation teeth 22, medium injection port 24, and medium delivery port allow the heating medium to exchange heat with the inner partition 12 through the heat dissipation teeth 22 when the temperature of the inner partition 12 is too high, thereby reducing the temperature of the inner partition 12.
[0039] It should be noted that this utility model only protects the mechanical part, and the functions implemented by the software control part are not within the scope of protection of this utility model.
[0040] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
