DETAILED DESCRIPTION

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0037] See also Figure 1-Figure 4 , a hot extrusion cooling and shaping device for automobile sound insulation and heat insulation materials, including a water collecting frame 1 for collecting coolant.

[0038] See also Figure 1 and Figure 7 The hot extrusion cooling and shaping equipment of automobile sound insulation and heat insulation materials also includes a cooling device 2, which is arranged on the water collecting frame 1 and is used to cool the sound insulation and heat insulation materials. The cooling device 2 includes a cooling frame 21 obliquely arranged above the water collecting frame 1, and the starting end of the cooling frame 21 is higher than the ending end. The bottom wall of the cooling frame 21 is wavy, and the lower ends of the multiple troughs on the bottom wall of the cooling frame 21 are all installed with support plates, and the lower end of the support plate is fixedly connected to the inner end of the bottom wall of the water collecting frame 1.

[0039] During specific operation, the water collecting frame 1 is fixed below the discharge port of the existing extrusion equipment. The water collecting frame 1 fixes the starting end of the cooling frame 21 at the discharge port of the extrusion equipment through multiple support plates, and then the coolant is injected into the water collecting frame 1.

[0040] See also Figure 1 and Figure 5The hot extrusion cooling and shaping equipment of the automobile sound insulation and heat insulation material also includes a water inlet device 4, which is arranged on the water collecting frame 1 and is used for conveying the coolant. The water inlet device 4 includes a water pump 41 installed on the upper end of the water collecting frame 1, and a water inlet pipe 42 is installed on the water pump 41. The lower end of the water inlet pipe 42 is located in the water collecting frame 1, and the upper end of the water inlet pipe 42 is located in the cooling frame 21. A heating module 43 is installed on the water inlet pipe 42.

[0041] During specific operation, the heating module 43 is an existing heating device. Initially, the water pump 41 and the heating module 43 are connected to the existing power supply, and then the water pump 41 and the heating module 43 are started. The water pump 41 absorbs the coolant in the water collecting frame 1 through the water inlet pipe 42. The coolant is heated to the required temperature through the heating module 43, and the heated coolant is discharged from the outlet of the water inlet pipe 42 to the starting end of the cooling frame 21.

[0042] See also Figure 5 and Figure 6 A cooling mechanism 22 is provided between any two adjacent troughs on the bottom wall of the cooling frame 21. The cooling mechanism 22 includes a connecting square tube 221 installed between two adjacent troughs. A cooling tube 222 for cooling the coolant is installed in the connecting square tube 221, and the cooling tube 222 is in a horizontal state.

[0043] See also Figure 5 and Figure 6 The cooling mechanism 22 further includes two baffle nets 223 respectively installed at the two open ends of the connecting square tube 221 , and a guide branch chain 224 is connected inside the connecting square tube 221 .

[0044] During specific operation, the cooling pipe 222 is initially connected to the existing cold water system, and the cold water system is connected to continuously inject cold water into the cooling pipe 222. During operation, as the coolant is injected into the water inlet pipe 42, the liquid level in the trough at the starting end of the cooling frame 21 gradually rises and overflows the corresponding connecting square tube 221, and the coolant flows into the connecting square tube 221 and contacts the cooling pipe 222 with cold water flowing therein, and the baffle net 223 blocks impurities in the coolant, and the cooling pipe 222 cools the coolant, and the cooled coolant flows out of the connecting square tube 221 and falls into the next trough on the bottom wall of the cooling frame 21, and so on, the coolant gradually fills multiple troughs of the cooling frame 21 and falls into the water collecting frame 1 from the end end of the cooling frame 21, and the temperature of the coolant in multiple troughs from the starting end to the end end of the cooling frame 21 gradually decreases and the coolant continues to flow.

[0045] Then, the extrusion equipment extrude the sound insulation and heat insulation material, and the sound insulation and heat insulation material enters the cooling frame 21 from the starting end of the cooling frame 21 and moves out from the ending end of the cooling frame 21 .

[0046] See also Figure 5 and Figure 6 The guide branch chain 224 includes a guide plate 2241 obliquely installed between the inner end of the upper tube wall of the connecting square tube 221 and the cooling tube 222, the guide plate 2241 is located at the upper left end of the cooling tube 222, and an arc plate 2242 located at the lower right side of the cooling tube 222 is installed at the inner end of the lower tube wall of the connecting square tube 221, and a space for the flow of coolant is set between the arc plate 2242 and the cooling tube 222.

[0047] During specific operation, when the coolant is cooled, the coolant entering the connecting square tube 221 is guided by the guide plate 2241, so that the coolant flows from the bottom of the cooling tube 222 and then flows to the inner arc surface of the arc plate 2242. The arc plate 2242 blocks the coolant, thereby increasing the contact time between the coolant and the cooling tube 222, ensuring that the coolant is effectively cooled. As the liquid level on the inner arc surface of the arc plate 2242 rises, the coolant overflows the arc plate 2242 and flows out from the oblique lower end of the connecting square tube 221.

[0048] See also Figure 1 and Figure 2 The hot extrusion cooling and shaping equipment of the automobile sound insulation and heat insulation material also includes a limiting device 3, which is arranged on the cooling frame 21. The limiting device 3 includes a plurality of evenly distributed U-shaped frames 31 which are installed at the open end of the cooling frame 21 with their openings facing downwards. A pushing mechanism 32 for pushing the sound insulation and heat insulation material is connected to the middle section of the U-shaped frame 31. A strip plate 33 is commonly installed on the plurality of pushing mechanisms 32. Two positioning mechanisms 34 which are symmetrically distributed front and back are commonly connected to the outer end surfaces of the middle sections of the plurality of U-shaped frames 31.

[0049] During specific operation, after the sound insulation and heat insulation material is placed in the cooling frame 21 , the strip plate 33 is pressed, and the strip plate 33 presses the sound insulation and heat insulation material into multiple troughs of the cooling frame 21 through multiple pushing mechanisms 32 , and the positioning mechanism 34 limits the moving pushing mechanism 32 .

[0050] See also Figure 1 and Figure 8 The pushing mechanism 32 includes a U-shaped rod 321 with an opening sliding downward and connected to the middle section of the U-shaped frame 31. The top of the U-shaped rod 321 is fixedly connected to the strip plate 33. A plurality of evenly distributed locking openings 322 are provided on the opposite ends of the front and rear sections of the U-shaped rod 321. A return spring 325 located on the inner side of the U-shaped rod 321 is installed at the inner end of the middle section of the U-shaped frame 31.

[0051] See also Figure 1 and Figure 8The pushing mechanism 32 also includes a rotating frame 323 with a U-shaped structure and an opening facing downward, which is installed at the open end of the U-shaped rod 321. The middle section of the rotating frame 323 is fixedly connected to the lower end of the reset spring 325. A guide wheel 324 is rotatably connected inside the rotating frame 323. The front and rear ends of the guide wheel 324 both pass through the vertical sections corresponding to the rotating frame 323. The front and rear ends of the guide wheel 324 are rotatably installed with multiple water-stirring plates 326 evenly distributed in the circumferential direction.

[0052] See also Figure 1 and Figure 7 The cooling device 2 also includes a plurality of temperature sensors 23 respectively connected to the inner ends of the rear frame walls of the cooling frame 21. The plurality of temperature sensors 23 are respectively located in a plurality of troughs on the bottom wall of the cooling frame 21. A plurality of sliding rollers 24 uniformly distributed in the circumferential direction are arranged on the inner sides of the plurality of troughs on the bottom wall of the cooling frame 21. The front and rear ends of the sliding rollers 24 are respectively rotatably connected to the front and rear frame walls of the cooling frame 21.

[0053] During specific operation, multiple temperature sensors 23 are used to monitor the temperature of water in multiple troughs of the bottom wall of the cooling frame 21. If the temperature exceeds the threshold, the temperature sensor 23 issues an early warning, and the operator controls the working conditions of the water pump 41 and the heating module 43 through the existing controller, thereby changing the flow rate of the coolant entering the cooling frame 21 and the temperature when entering. After the sound insulation and heat insulation material is placed in the cooling frame 21, the strip plate 33 is pressed, and the strip plate 33 drives the multiple U-shaped rods 321 to slide on the corresponding U-shaped frame 31, and the multiple U-shaped rods 321 pass through the corresponding rotating frame 323. The corresponding guide wheels 324 are driven to move toward the trough direction corresponding to the bottom wall of the cooling frame 21. The multiple guide wheels 324 first contact the sound insulation and heat insulation materials and push them into the multiple troughs of the bottom wall of the cooling frame 21. The multiple sliding rollers 24 in the troughs support the sound insulation and heat insulation materials to avoid the phenomenon that the coolant cannot cool the bottom of the sound insulation and heat insulation materials after the sound insulation and heat insulation materials contact the bottom wall of the cooling frame 21, thereby ensuring the cooling efficiency of the sound insulation and heat insulation materials. In addition, the multiple sliding rollers 24 facilitate the movement of the sound insulation and heat insulation materials. At this time, the sound insulation and heat insulation materials are wavy (such as Fig. 9 shown).

[0054] See also Figure 1 and Figure 8 The locking mechanism 34 includes a rectangular frame 341 installed at the top of multiple U-shaped frames 31 at the same time, and the end of the rectangular frame 341 close to the U-shaped rod 321 is slidably connected with a locking plate 342, and a plurality of evenly distributed connecting springs 343 are installed between the locking plate 342 and the inner end surface of the vertical side wall of the rectangular frame 341. The end of the locking plate 342 close to the U-shaped rod 321 is provided with a slope, and the locking plate 342 is plugged into and matched with any one of the locking openings 322.

[0055] See also Figure 7 A plurality of rotating rollers 211 are rotatably connected to the plurality of wave crests on the bottom wall of the cooling frame 21 .

[0056] During specific operation, while the U-shaped rod 321 moves, the multiple locking openings 322 on the U-shaped rod 321 push the slope of the locking plate 342, and the locking plate 342 moves into the rectangular frame 341 under the force and squeezes the connecting spring 343. When the sound insulation and heat insulation materials come into contact with the multiple sliding rollers 24, the locking plate 342 is locked in the corresponding locking openings 322, realizing the function of limiting the U-shaped rod 321, ensuring that the guide wheel 324 always squeezes the sound insulation and heat insulation materials.

[0057] Finally, the end of the sound insulation and heat insulation material is connected to the existing traction equipment, and the traction equipment is started. The traction equipment pulls the sound insulation and heat insulation material, and the sound insulation and heat insulation material moves in the cooling frame 21 along the shape of the bottom wall of the cooling frame 21. The multiple rotating rollers 211 play the role of reducing the friction between the sound insulation and heat insulation material and the cooling frame 21. The sound insulation and heat insulation material drives the guide wheel 324 to rotate while moving, and the guide wheel 324 drives the multiple water stirring plates 326 at both ends to rotate. The water stirring plates 326 stir the cooling liquid around the sound insulation and heat insulation material to avoid the phenomenon that the cooling liquid around the sound insulation and heat insulation material rises in temperature after cooling and cannot be quickly separated from the sound insulation and heat insulation material, thereby ensuring the efficiency of the cooling liquid in cooling the sound insulation and heat insulation material. The cooling liquid at different temperatures in the cooling frame 21 performs multi-stage cooling treatment on the sound insulation and heat insulation material to avoid the phenomenon of rapid cooling of the extruded sound insulation and heat insulation material, thereby avoiding the phenomenon of stress concentration or surface defects in the sound insulation and heat insulation material. After the sound insulation and heat insulation material is completely cooled, the cooling is completed.

[0058] In addition, the present invention also provides a method for hot extrusion cooling and shaping of sound insulation and heat insulation materials for automobiles, which specifically includes the following steps: S1: Fix the water collecting frame 1 under the discharge port of the existing extrusion equipment, and the water collecting frame 1 fixes the starting end of the cooling frame 21 at the discharge port of the extrusion equipment through multiple support plates, and then injects the coolant into the water collecting frame 1, and then connects the cooling pipe 222 to the existing cold water system, and the cold water system continuously injects cold water into the cooling pipe 222.

[0059] S2: Start the water pump 41, the water pump 41 sucks the coolant in the water collecting frame 1 into the water inlet pipe 42, the heating module 43 heats the coolant in the water inlet pipe 42 to the required temperature, and the heated coolant enters the trough at the starting end of the cooling frame 21 through the water inlet pipe 42.

[0060] S3: The liquid level in the trough at the starting end of the cooling frame 21 gradually rises and overflows the corresponding connecting square tube 221, the coolant flows into the connecting square tube 221 and contacts the cooling tube 222 with cold water flowing therein, the cooling tube 222 cools the coolant, and the cooled coolant flows out of the connecting square tube 221 and falls into the next trough on the bottom wall of the cooling frame 21, and so on, the coolant gradually fills up multiple troughs of the cooling frame 21 and falls into the water collecting frame 1 from the ending end of the cooling frame 21, and the temperature of the coolant in multiple troughs of the cooling frame 21 from the starting end to the ending end gradually decreases.

[0061] S4: The extrusion equipment extrude the sound insulation and heat insulation material, which enters the cooling frame 21 from the starting end of the cooling frame 21 and moves out from the ending end of the cooling frame 21. Then, the strip plate 33 is pressed, and the strip plate 33 presses the sound insulation and heat insulation material into multiple troughs of the cooling frame 21 through multiple pushing mechanisms 32. The positioning mechanism 34 limits the moving pushing mechanism 32.

[0062] S5: After the completion of step S4, the end of the sound insulation and heat insulation material is connected to the existing traction equipment, and the traction equipment is started. The traction equipment pulls the sound insulation and heat insulation material, and the sound insulation and heat insulation material moves in the cooling frame 21 along the shape of the bottom wall of the cooling frame 21. The coolant of different temperatures in the cooling frame 21 cools the sound insulation and heat insulation material until the sound insulation and heat insulation material is completely cooled, and the cooling is completed.
