Description

Technical Field

[0001] This utility model relates to the field of automotive interior foam material processing technology, and in particular to a pre-storage device for automotive interior foam material processing. Background Technology

[0002] In the automotive interior manufacturing industry, foamed materials (such as two-component materials like polyurethane foam) are widely used due to their excellent cushioning, sound insulation, and lightweight properties. Two-component foamed materials typically consist of a prepolymer (component A) and a curing agent (component B). Traditionally, storage and processing involve storing both components in separate containers, relying on manual handling, proportioning, and mixing during use. This approach has several drawbacks: First, manual operation makes it difficult to precisely control the ratio of the two components, easily leading to uneven mixing and affecting the molding quality and physical properties of the foamed material. Second, frequent manual transfers expose the material to the external environment, making it susceptible to impurities or reactions with air, resulting in material deterioration and performance degradation. Third, separate storage containers occupy a large amount of space and lack integrated management, leading to low warehousing efficiency and high production costs.

[0003] In addition, two-component materials have stringent environmental requirements for storage. Fluctuations in parameters such as temperature and humidity may cause premature curing or chemical deterioration of the materials. However, existing storage devices often lack effective temperature monitoring and control methods, which cannot meet the high-quality storage requirements of the materials.

[0004] Therefore, it is necessary to design a pre-storage device for processing automotive interior foam materials to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pre-storage device for processing automotive interior foam materials. This device enables the isolated storage of two-component materials, automatic proportioning and mixing, and environmental monitoring, thereby improving the processing efficiency and product quality of automotive interior foam materials and reducing production costs and human error.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A pre-storage device for processing automotive interior foam materials includes a lower storage tank and an upper storage tank. The upper storage tank is fixedly connected to the upper end of the lower storage tank. The upper and lower storage tanks are connected through a connecting channel, on which a first solenoid valve is provided. Feed hoppers are connected to the left sides of both the upper and lower storage tanks. A first stirring assembly is provided inside the upper storage tank, and a second stirring assembly is provided inside the lower storage tank. The first stirring assembly includes a vertical rod rotatably connected to the top of the upper storage tank, with multiple first stirring rods fixedly connected to the outer wall of the vertical rod. The second stirring assembly includes horizontal rods rotatably connected to the inner walls of the left and right sides of the lower storage tank, with multiple second stirring rods fixedly connected to the outer wall of the horizontal rods. A drive motor is installed on the left side of the lower storage tank, and the output shaft of the drive motor is fixedly connected to the horizontal rods.

[0008] Preferably, an installation block is fixedly connected to the upper end of the upper storage tank, and a transmission rod is rotatably connected through the installation block. The upper end of the vertical rod and the right end of the horizontal rod both extend to the outside. Both the transmission rod and the vertical rod are provided with meshing bevel gears. The horizontal rod and the transmission rod are connected by a first transmission assembly.

[0009] Preferably, temperature sensors are installed on the front side of both the upper and lower storage tanks, and the sensing ends of the temperature sensors extend into the corresponding upper or lower storage tank.

[0010] Preferably, the upper storage tank is provided with a first cooling assembly, the first cooling assembly includes a threaded pipe rotatably connected to the top of the upper storage tank, a liquid storage tank is installed on the rear side of the upper storage tank, a pump body is placed at the bottom of the liquid storage tank, the outlet end of the pump body is connected to the inlet pipe, the top space of the liquid storage tank is connected to an outlet pipe, both the inlet pipe and the outlet pipe are provided with rotary joints, and both ends of the threaded pipe are connected to the two rotary joints.

[0011] Preferably, the threaded tube consists of a threaded section and a vertical section, the upper end of the vertical section extends to the outside, and the vertical section is connected to the vertical rod through a second transmission assembly.

[0012] Preferably, the lower storage tank is provided with a second cooling assembly, the second cooling assembly including a heat exchanger fixedly connected to the outer wall of the lower storage tank, the liquid inlet end of the heat exchanger being connected to the liquid outlet end of the pump body through a first vertical pipe, the liquid outlet end of the heat exchanger being connected to the bottom space of the storage tank through a second vertical pipe, and a second solenoid valve being provided on both the first vertical pipe and the liquid inlet pipe.

[0013] Compared with existing technologies, the advantages of this device are:

[0014] 1. Compared with the existing technology, this device achieves partitioned storage and controllable communication of two-component materials through the design of an isolated double-chamber tank (upper storage tank and lower storage tank) and a connecting channel, avoiding premature contact and reaction between the two components; with the opening and closing control of the first solenoid valve, the material mixing timing can be precisely adjusted. Compared with the traditional method of manual handling and mixing in independent containers, it significantly improves the safety of material storage and mixing efficiency, and reduces human operation error.

[0015] 2.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-3 A pre-storage device for processing automotive interior foam materials includes a lower storage tank 1 and an upper storage tank 2. The upper storage tank 2 is fixedly connected to the upper end of the lower storage tank 1. The upper storage tank 2 and the lower storage tank 1 are connected through a connecting channel 23. A first solenoid valve is provided on the connecting channel 23. The solenoid valve is bidirectional and controllable. The opening time and opening degree are precisely adjusted by a PLC control system to achieve precise control of material flow. A feed hopper 5 is connected to the left side of both the upper storage tank 2 and the lower storage tank 1. A first stirring assembly is provided in the upper storage tank 2, and a second stirring assembly is provided in the lower storage tank 1. The first stirring assembly includes a vertical rod 17 rotatably connected to the top of the upper storage tank 2. Multiple first stirring rods 18 are fixedly connected to the outer wall of the vertical rod 17. The second stirring assembly includes a horizontal rod 19 rotatably connected to the inner walls of the left and right sides of the lower storage tank 1. Multiple second stirring rods 20 are fixedly connected to the outer wall of the horizontal rod 19. A drive motor 4 is installed on the left side of the lower storage tank 1. The output shaft end of the drive motor 4 is fixedly connected to the horizontal rod 19.

[0023] The upper storage tank 2 is fixedly connected to the upper end of the mounting block 12, and the mounting block 12 is rotatably connected to the transmission rod 13. The upper end of the vertical rod 17 and the right end of the horizontal rod 19 both extend to the outside. The transmission rod 13 and the vertical rod 17 are provided with bevel gears 14 that mesh with each other. The horizontal rod 19 and the transmission rod 13 are connected by transmission through the first transmission assembly 11. The first transmission assembly 11 includes a first sprocket set on the transmission rod 13 and the horizontal rod 19. The two first sprockets are connected by transmission through the first chain.

[0024] Temperature sensors 3 are installed on the front side of both the upper storage tank 2 and the lower storage tank 1. The sensing end of the temperature sensor 3 extends into the corresponding upper storage tank 2 or lower storage tank 1 to monitor the temperature of the material inside the tank in real time.

[0025] The upper storage tank 2 is equipped with a first cooling assembly, which includes a threaded pipe 21 rotatably connected to the top of the upper storage tank 2. A liquid storage tank 9 is installed on the rear side of the upper storage tank 2 and is filled with coolant. A pump body is placed at the bottom of the liquid storage tank 9, and the outlet end of the pump body is connected to the inlet pipe 10. An outlet pipe 22 is connected to the top space of the liquid storage tank 9. Both the inlet pipe 10 and the outlet pipe 22 are equipped with rotary joints 16. The two ends of the threaded pipe 21 are connected to the two rotary joints 16. The threaded pipe 21 consists of a threaded section and a vertical section. The upper end of the vertical section extends to the outside. The vertical section is connected to the vertical rod 17 through a second transmission assembly 15. The second transmission assembly 15 includes second sprockets set on the vertical rod 17 and the vertical section. The two second sprockets are connected through a second chain. A control system is provided. A temperature sensor 3 collects the internal temperature data of the storage tank in real time and feeds the information back to the control system. When the temperature exceeds the set threshold, the system automatically starts the pump body.

[0026] The lower storage tank 1 is equipped with a second cooling assembly, which includes a heat exchanger 6 fixedly connected to the outer wall of the lower storage tank 1. The liquid inlet end of the heat exchanger 6 is connected to the liquid outlet end of the pump body through a first vertical pipe 7. The liquid outlet end of the heat exchanger 6 is connected to the bottom space of the storage tank 9 through a second vertical pipe 8. Both the first vertical pipe 7 and the liquid inlet pipe 10 are equipped with a second solenoid valve.

[0027] The functional principle of this utility model can be explained through the following operation: This utility model uses an upper storage tank 2 and a lower storage tank 1 arranged vertically, in conjunction with a first solenoid valve in a closed state, to independently store components A and B of the two-component foaming material through the feed hopper 5. By utilizing the isolation characteristics of the connecting channel 23, the two components are effectively prevented from undergoing a chemical reaction in advance, thus ensuring the safety of material storage.

[0028] During the mixing process, after the drive motor 4 is started, its output shaft drives the horizontal bar 19 in the lower storage tank 1 to rotate, and the second stirring rod 20 on the horizontal bar 19 then stirs the material in the tank. At the same time, the horizontal bar 19 drives the transmission rod 13 to rotate through the first transmission assembly 11. The transmission rod 13 meshes with the bevel gear 14 on the vertical bar 17, thereby driving the vertical bar 17 and the first stirring rod 18 in the upper storage tank 2 to operate synchronously, realizing the simultaneous stirring of the materials in the upper and lower storage tanks 1. After the two components are stirred evenly, the first solenoid valve is opened, and the material in the upper storage tank 2 flows into the lower storage tank 1 through the connecting channel 23. The second stirring assembly in the lower storage tank 1 continues to work to ensure that the two components are fully mixed.

[0029] In terms of temperature monitoring and control, temperature sensor 3 collects real-time temperature data inside the storage tank and feeds the information back to the control system. When the temperature exceeds the set threshold, the system automatically starts the pump, allowing the coolant to enter the threaded pipe 21 sequentially through the inlet pipe 10 and the rotary joint 16. Under the action of the second transmission assembly 15, the threaded pipe 21 rotates continuously, significantly increasing the heat exchange area between the coolant and the material in the upper storage tank 2. At the same time, the coolant flows into the heat exchanger 6 through the outlet pipe 22 and circulates through the first vertical pipe 7 and the second vertical pipe 8, forming the second cooling assembly to cool the lower storage tank 1 and the entire system, thereby maintaining the temperature stability of the material storage environment.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
