Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts processing technology, and in particular to a temperature-changing mechanism for a structural adhesive supply tank. Background Technology
[0002] Structural adhesives are increasingly used in automotive parts. Factories use coating equipment to mix the structural adhesive evenly and apply it to the parts, ensuring a strong bond between them. Structural adhesives exhibit different physical properties at different temperatures. At low temperatures, the viscosity is high, requiring greater pressure to extrude the adhesive; at high temperatures, the viscosity is low, necessitating lower extrusion pressure. This presents a significant challenge to the coating equipment.
[0003] Since glue coating equipment cannot automatically adjust the extrusion pressure, it often triggers alarms due to abnormal glue ratios. To reduce the frequency of these alarms, glue coating equipment manufacturers typically require the factory to establish a dedicated glue room. This room is kept at a constant temperature, and the glue tanks of the glue coating equipment are stored within it. Under these conditions, the pressure of the glue coating equipment is adjusted to further reduce the frequency of alarms.
[0004] However, this method requires a larger area to build the glue room and incurs higher costs, which is not conducive to the factory's cost reduction, efficiency improvement, and sustainable development. Utility Model Content
[0005] In view of the above problems, this utility model provides a temperature-changing mechanism for a structural adhesive supply tank.
[0006] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:
[0007] A temperature-changing mechanism for a structural adhesive supply tank is provided, comprising a tank body and an insulation layer. The tank body is used to hold structural adhesive, and the bottom of the tank body is provided with an adhesive outlet pipe. The insulation layer is sleeved on the outside of the tank body and covers the bottom of the tank body. The adhesive outlet pipe passes through the insulation layer and is connected to a mixing valve. The outer wall of the insulation layer is provided with a water inlet and a water outlet, and the water inlet is connected to a hot water source.
[0008] Furthermore, the inlet is higher than the outlet.
[0009] Furthermore, both the plastic can body and the insulation layer are made of stainless steel, and the insulation layer is connected to the plastic can body by welding.
[0010] Furthermore, the hot water inlet includes a water temperature controller connected to the water source.
[0011] Furthermore, a connecting flange is fixedly installed at the bottom of the insulation layer. The connecting flange is used to support the insulation layer and the glue tank body, and is detachably connected to the installation platform of the glue tank body.
[0012] Furthermore, a cover plate is detachably provided on the top of the glue can body, and a connector for detachably connecting the cover plate is provided on the outside of the glue can body. The connector includes a screw that is hinged to the outside of the glue can body. Limiting grooves for the screw to rotate and be inserted are provided on the edges of both the glue can body and the cover plate. Multiple screws are evenly spaced along the circumference of the glue can body. A positioning knob is threaded on the screw. The screw fixes the cover plate by abutting against the top wall of the cover plate.
[0013] The beneficial effects of this utility model are as follows: by continuously introducing constant-temperature hot water into the insulation cavity from the water inlet of the insulation layer, the temperature of the structural adhesive in the glue tank body can be maintained, thereby achieving constant temperature control of the structural adhesive in the glue tank body, ensuring small fluctuations in adhesive viscosity and stable adhesive ratio. During the process of extruding the structural adhesive in the glue tank body to the mixing valve, the fluidity of the structural adhesive is maintained. Moreover, the insulation layer is integrated into the glue tank body, resulting in a simple structure and low equipment cost. Attached Figure Description

[0017] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0018] Example 1
[0019] This application discloses a temperature-changing mechanism for a structural adhesive supply tank, referring to... Figure 1 The system includes a glue tank body 1 and an insulation layer 2. The glue tank body 1 is used to hold structural adhesive. The insulation layer 2 covers the outside of the glue tank body 1 and the bottom of the glue tank body 1. An insulation cavity for the flow of insulation medium is formed between the insulation layer 2 and the glue tank body 1. The outer wall of the insulation layer 2 is provided with a water inlet 21 and a water outlet 22. The water inlet 21 is connected to a hot water source, and the water outlet 22 is connected to a liquid supply water circulation system. The bottom of the glue tank body 1 is connected to a glue outlet pipe 11, which passes through the insulation layer 2 and is connected to a glue mixing valve.
[0020] After adding glue to the glue tank body 1, hot water at a constant temperature is injected from the water inlet 21 between the insulation layer 2 and the glue tank body 1. The hot water at a constant temperature exchanges heat with the structural glue in the glue tank body 1, maintaining the constant temperature of the structural glue in the glue tank body 1. This allows the structural glue in the glue tank body 1 to maintain its own fluidity during the extrusion process. There is no need to build a constant temperature glue chamber. The structure is simple and the equipment cost is low.
[0021] Specifically, both the insulation layer 2 and the adhesive tank body 1 are made of stainless steel. The insulation layer 2 and the adhesive tank body 1 are connected by welding. The insulation layer 2 and the adhesive tank body 1 are rust-proof, durable, and easy to clean. The water inlet 21 on the insulation layer 2 is higher than the water outlet 22. After hot water enters from the water inlet 21, it can completely cover the bottom of the adhesive tank body 1, allowing the hot water to fully exchange heat with the structural adhesive inside the adhesive tank body 1, thereby improving the temperature regulation effect on the structural adhesive.
[0022] In this embodiment, a cover plate 6 is detachably mounted on the top of the glue container body 1. The cover plate 6 has an inlet pipe and an air inlet pipe for introducing structural adhesive into the glue container body 1 and for pressurizing the glue container body 1 to discharge the structural adhesive. The cover plate 6 is sealed to the top of the glue container body 1 by a sealing ring. A connector 5 for detachably connecting the cover plate 6 is provided on the outer side of the glue container body 1. In this embodiment, the connector 5 includes a screw hinged to the outer side of the glue container body 1. Limiting grooves for the screw to rotate and embed are provided on the edges of both the glue container body 1 and the cover plate 6. Multiple screws are evenly spaced along the circumference of the glue container body 1, and a positioning knob is threaded onto the screw. The screw abuts against the top wall of the cover plate 6 to fix the cover plate 6. The limiting and fixing of the cover plate 6 is convenient and quick.
[0023] A connecting flange 4 is also provided at the bottom of the insulation layer 2. The insulation layer 2 and the glue tank body 1 are supported on the installation platform where the glue tank body 1 needs to be installed by the connecting flange 4. A connecting hole is provided through the connecting flange 4. The connecting flange 4 is detachably connected to the installation platform by connecting bolts.
[0024] In this embodiment of the application, the hot water inlet includes a water temperature controller connected to the water source. The water source can be a circulating water tank in the factory or tap water. The water temperature controller heats the water and controls the temperature of the output water.
[0025] Example 2
[0026] Reference Figure 2 The difference between Example 2 and Example 1 is that the bottom of the insulation layer 2 is provided with a scale collection tank 3 and a scale discharge box 31.
[0027] Specifically, the scale collection tank 3 is coaxially positioned at the bottom of the insulation layer 2, with an opening at the top to connect it to the insulation cavity. A scale discharge box 31 is detachably installed at the bottom of the scale collection tank 3, and the inner bottom wall of the scale collection tank 3 is inclined towards the scale discharge box 31. When hot water flows through the insulation cavity for a long time, scale and other impurities from the pipes are easily flushed into the insulation cavity and accumulate, affecting the temperature control effect on the structural adhesive inside the tank. With the scale collection tank 3 installed, impurities in the insulation cavity are collected into the scale collection tank 3. Workers can periodically remove the scale discharge box 31 to clean the collected impurities, maintaining smooth flow of hot water in the insulation cavity.
[0028] Furthermore, a limiting ring 32 is provided around the top opening edge of the scale collection tank 3. The inner edge of the limiting ring 32 is inclined towards the inside of the scale collection tank 3. By setting the limiting ring 32, when the hot water flows in the heat preservation cavity, the impurities in the scale collection tank 3 are blocked by the limiting ring 32 as they are carried upward by the water flow, so that the impurities can be stably stored in the scale collection tank 3.
