Description

Technical Field

[0001] This application belongs to the technical field of TPU braiding, specifically relating to a hot pressing device for TPU braiding molding and its working method. Background Technology

[0002] TPU, thermoplastic polyurethane elastomer, also known as thermoplastic polyurethane rubber, is a (AB)n-type block linear polymer. A is a high molecular weight polyester or polyether (1000-6000), and B is a diol containing 2-12 straight-chain carbon atoms. The chemical structure between the AB segments is a diisocyanate. Thermoplastic polyurethane rubber is cross-linked by intermolecular hydrogen bonds or by slight cross-linking between macromolecular chains. These two cross-linking structures are reversible with increasing or decreasing temperature. In the molten or solution state, intermolecular forces weaken, but after cooling or solvent evaporation, strong intermolecular forces reconnect them, restoring the original solid properties. Typical TPUs, such as spandex, possess excellent comprehensive properties including high strength, high toughness, wear resistance, and oil resistance. They also have good processing performance and are widely used in defense, medical, and food industries.

[0003] Most existing TPU finished products use a method of shaping after weaving. For example, a method for preparing a TPU fire hose (authorization announcement number: CN102514208B) involves a production process for fire hoses used to prepare a TPU inner lining. The method for preparing a TPU fire hose of the present invention includes the following steps: A, forming a cylindrical braided layer of the hose tube by three-dimensional weaving of warp and weft threads; B, preparing TPU material; C, placing the TPU material in a cylindrical mold groove and then covering it with the cylindrical braided layer; D, fitting the cylindrical mold groove and the cylindrical braided layer into an electromagnetically heated cylindrical tube, and energizing and controlling the electromagnetic heating process; E, cooling the cylindrical mold groove. It may also include the following steps: F, processing to obtain a cylindrical outer covering layer; G, applying an adhesive to the cylindrical outer covering layer and pulling it into the cylindrical braided layer; H, rolling to fix the hose wall.

[0004] Although the aforementioned patent can weave TPU strips, the overall shape is fixed before heating and molding, which can easily lead to misalignment or processing errors, resulting in a low yield of finished products. There is an urgent need for a solution to address these issues. Summary of the Invention

[0005] One of the objectives of this application is to provide a hot pressing device for TPU braiding molding, which addresses the shortcomings of existing technologies. In practical applications, the device forms alternating strips by moving the first and second lower mold components of the lower mold mechanism. The hot pressing mechanism works in conjunction with this device, and each strip is hot-pressed during the weaving process. This allows for automatic weaving processing with high precision, thereby improving the product qualification rate and processing speed.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] A hot pressing device for TPU braiding molding, 1. comprising:

[0008] The material conveying and shearing mechanism includes a corresponding conveying component, a pressing component, and a shearing component;

[0024] The clamping assembly transports the sheared strip to the lower die template in the lower die mechanism. The upper die template in the hot pressing mechanism moves downward to hot press the strip. The lifting and translation movements of the first and / or second lower die assemblies cause their respective lower die templates to shift, forming alternating strips.

The lower mold plates corresponding to the first lower mold assembly and / or the second lower mold assembly are moved by the lifting and translational movements of the first lower mold assembly and / or the second lower mold assembly, forming alternating strips. The above process is repeated. Since TPU has adhesiveness after being hot pressed, multiple strips are glued together to form a shape. This application can complete the automatic weaving process of TPU strips, improve the product processing speed, reduce labor costs, and each strip is hot-pressed during the weaving process, which can improve the processing accuracy and thus improve the product qualification rate.

[0050] The following is in conjunction with the appendix Figures 1-8 The present application will be further described in detail with reference to specific implementation methods, but this is not intended to limit the present application.

[0051] Implementation Method 1

[0052] like Figure 1-2 As shown, a hot pressing device for TPU braiding includes a base frame 8, a cover 9 covering the base frame 8, an accommodating space formed inside the cover 9, and a high-frequency component 10 disposed outside the cover 9. The base frame 8 is provided with a discharge port 81. The material strip clamping and pulling mechanism 2, the material strip clamping and conveying mechanism 3, the lower mold mechanism 4, the hot pressing mechanism 6, and part of the material strip conveying and shearing mechanism 1 are all located within the accommodating space. The material strip clamping and conveying mechanism 3 is arranged perpendicularly to the material strip clamping and pulling mechanism 2. There are two material strip clamping and conveying mechanisms 3, which are respectively located on both sides of the lower mold mechanism 4 to transport the material strip to be processed to the lower mold mechanism 4. The hot pressing mechanism 6 is correspondingly disposed above the lower mold mechanism 4. The high-frequency component 10 provides energy to the hot pressing mechanism 6.

[0053] In practical applications, the strip conveying and shearing mechanism 1 conveys and shears the strip to be processed. The strip clamping and pulling mechanism 2 and the strip clamping and conveying mechanism 3 assist in the strip shearing work and convey the strip to the lower die mechanism 4. The strip conveyed to the set position of the lower die mechanism 4 is hot-pressed by the descending hot pressing mechanism 6. Then, the lower die mechanism 4 alternately moves the strip by lifting and translating. In this embodiment, the hot pressing device completes the automatic processing of strip weaving by repeating the above steps, which improves the product processing speed, reduces labor costs, and each strip is hot-pressed during the weaving process, which can improve the processing accuracy and thus improve the product qualification rate.

[0054] like Figure 5 As shown, the material conveying and shearing mechanism 1 includes a conveying component 11, a pressing component 12, and a shearing component 13. The conveying component 11 includes a first mounting frame 111 and a plurality of matching turntables 112 mounted on the first mounting frame 111. The pressing component 12 includes a second mounting frame 121 and a pressing base block 122 mounted on the second mounting frame 121, a pressing groove 1221 formed in the pressing base block 122, and a pressing block 123 corresponding to the pressing groove 1221. The second mounting frame 121 includes a horizontal plate 1211 and a vertical plate 1212 arranged perpendicularly to each other. The pressing base block 122 is mounted on the horizontal plate 1211. 211, a material receiving wheel 124 is also provided on the horizontal plate 1211. The material receiving wheel 124 is located between the input end of the pressing block 122 and the output end of the turntable 112. A material fixing passage 1222 is also provided on the pressing block 122, which runs through its surface. The pressing groove 1221 is located in the material fixing passage 1222. A pressing power cylinder 125 is provided on the vertical plate 1212. A pressing block 123 is located at the output end of the pressing power cylinder 125. The material fixing passage 1222 facilitates the transportation of the material. The setting of the pressing groove 1221 and the pressing block 123 increases the accuracy of the shearing component 13.

[0055] like Figure 5 As shown, the shearing assembly 13 includes a first power cylinder 131, a mounting plate 132 mounted on the output end of the first power cylinder 131, a shearing power cylinder 133 mounted on the mounting plate 132, and a shearing element 134 located at the output end of the shearing power cylinder 133. The first power cylinder 131 is mounted on the vertical plate 1212, and the shearing element 134 is correspondingly arranged with the pressing groove 1221.

[0056] like Figure 6As shown, the strip clamping and pulling mechanism 2 is correspondingly arranged with the output end of the strip conveying and shearing mechanism 1, including a first translation component 21 and a pulling component 22 disposed on the first translation component 21. The first translation component 21 includes a third mounting frame 71, a translation long mold 72 fixedly mounted on the third mounting frame 71, a second power cylinder 73 mounted on the translation long mold 72, and a sliding base 74 slidably disposed on the translation long mold 72. The pulling component 22 includes a fifth mounting frame 221 and a pulling clamp body mounted on the fifth mounting frame 221. 222 and a pulling power cylinder 223 for driving the pulling clamp body 222, the fifth mounting bracket 221 is mounted on the corresponding sliding base 74; in practical applications, the pulling clamp body 222 in the material strip clamping and pulling mechanism 2 pulls the material strip transported by the material strip transport and shearing mechanism 1 to a set position. In this embodiment, it is pulled to a position close to another material strip transport and shearing mechanism 1 so that its length is greater than the length of the two lower die templates 53 spliced ​​in the lower die mechanism 4, so as to ensure the normal operation of the hot pressing device weaving work.

[0057] like Figure 8 As shown, the material conveying and clamping mechanism 3 includes a second translation component 31 and a clamping component 32 disposed on the second translation component 31. The structure of the second translation component 31 is the same as that of the first translation component 21. However, in this embodiment, the positions of the second power cylinders 73 of the two are different, but the principle and function are the same. The clamping component 32 includes a fourth mounting frame 321, a third power cylinder 322 mounted on the fourth mounting frame 321, a second moving plate 323 disposed at the output end of the third power cylinder 322, a clamping clamp body 324 mounted on the second moving plate 323, and a clamping power cylinder 325 for driving the clamping clamp body 324. The fourth mounting frame 321 is mounted on the corresponding sliding base 74.

[0058] The specific workflow for transporting and cutting the strip to be processed by the above three mechanisms is as follows: the turntable 112 is connected to the external strip supply device such as the strip roll, the strip to be processed flows in the passage formed by multiple turntables 112 to the strip fixed passage 1222, the first translation component 21 operates to transport the pulling clamp body 222 to the fixed position, and then is pulled to the set position by the pulling clamp body 222, the second translation component 31 operates to transport the clamping clamp body 324 to the fixed position, and then is clamped by the clamping clamp body 324, the first power cylinder 131 operates, and the shearing element 134 is transported to the set position for shearing through the mounting plate 132, the second translation component 31 operates again to transport the strip cut to the set length through the clamping clamp body 324 to the lower mold template 53 of the lower mold mechanism 4.

[0059] It should be noted that in this embodiment, the clamping assembly 32 has an additional set of components for the vertical movement of the clamping body 324 compared to the pulling assembly 22. The main reason is that in this embodiment, the output end of the material conveying and shearing mechanism 1 is in a fixed position, so the vertical position of the pulling assembly 22 does not need to be adjusted. However, the lower mold mechanism 4 has multiple moving components whose positions are not fixed, so the position of the clamping assembly 32 needs to be adjusted. In other technical solutions of this embodiment, a component for vertical movement can be added below the output end of the material conveying and shearing mechanism 1, i.e., below the pressure base block 122. Then the clamping assembly 32 can be set to have the same structure as the pulling assembly 22, so that the clamping assembly 32 can match the position of the pressure base block 122.

[0060] like Figure 3-4 As shown, the lower mold mechanism 4 includes a base plate 41, a first power element 42 disposed on the base plate 41, a first guide rail 43 disposed on both sides of the base plate 41, and a first lower mold assembly 44 and a second lower mold assembly 45 respectively disposed on the first guide rail 43. The first lower mold assembly 44 and the second lower mold assembly 45 are respectively disposed and have the same structure, both including a first moving plate 51, a bracket 52 disposed on the first moving plate 51, a lower mold template 53 located at the top of the bracket 52, and a moving component disposed on the bracket 52. The first moving plate 51 is mounted on the first guide rail 43 and is respectively mounted on the output end of the corresponding first power element 42.

[0061] like Figure 3-4 As shown, the bracket 52 has a first mounting surface 521 and a second mounting surface 522 opposite to each other. The moving assembly includes a third power element 541, a first synchronous pulley 542 and a second synchronous pulley 543 mounted on the output end of the third power element 541, a synchronous belt 544 sleeved on the first synchronous pulley 542 and the second synchronous pulley 543, a lifting screw 545 located at the output end of the second synchronous pulley 543, and a side panel 546 connected to the lifting screw 545. The side panel 546 is connected to the lower mold template 53. The third power element 541 and the first synchronous pulley 542 are mounted on the first mounting surface 521, and the second synchronous pulley 543, the lifting screw 545 and the side panel 546 are mounted on the second mounting surface 522.

[0062] The specific operation mode of the lower mold mechanism 4 is as follows: the corresponding first power element 42 is used for the lateral translation movement of the first lower mold assembly 44 and the second lower mold assembly 45 as a whole, which can drive the translation movement of the corresponding lower mold template 53. The moving component is used for the lifting movement of the lower mold template 53. Specifically, when lifting movement is required, the third power element 541 drives the first synchronous wheel 542 to rotate. Due to the transmission connection of the synchronous belt 544, the second synchronous wheel 543 follows the first synchronous wheel 542 to rotate, thereby causing the lifting screw 545 to drive the side panel 546 to rise and fall, and finally drive the lower mold template 53 to rise or fall.

[0063] like Figure 7 As shown, the hot pressing mechanism 6 includes a gantry frame 61, a second power element 62 installed on the gantry frame 61, and an upper mold assembly 63 located at the output end of the second power element 62. The upper mold assembly 63 includes a movable body 632, a receiving body 633 connected to the movable body 632, and an upper mold template 631 installed on the receiving body 633 by mounting screws. The movable body 632 is connected to the output end of the second power element 62 and is installed by mounting screws for easy replacement.

[0064] In this embodiment, to manufacture a honeycomb-shaped TPU structure, the shapes of the lower mold template 53 and the upper mold template 631 are defined as follows: the edge of the lower mold template 53 is provided with a first tooth block 531, and the first tooth blocks 531 of the two lower mold templates 53 are configured to mesh with each other. The upper mold template 631 is provided with a plurality of second tooth blocks 6311 protruding in the direction close to the lower mold template 53. The second tooth blocks 6311 are arranged in two horizontal rows with a gap between the two rows of second tooth blocks 6311. The interval between two adjacent second tooth blocks 6311 in the same row is the same. The above structure can make the finished product a honeycomb-structured TPU product by alternating material strips during the manufacturing process. In other technical solutions of this embodiment, TPU products of other shapes can also be manufactured by changing the structure of the upper mold template 631 and the lower mold template 53.

[0065] It is understood that in this embodiment, the plate or other individual components used to install other objects or connect two components may be composed of multiple plates in different directions. In this embodiment, no detailed description is given. It is sufficient that they serve the purpose of bearing or connecting. Furthermore, the bottom of the movable component and the top of the component supporting the movable component have matching slide rails and sliders to guide it, or guide rods are provided to fix its movement direction.

[0066] Implementation Method 2

[0067] A method for operating a hot pressing device for TPU braiding as described in Embodiment 1, characterized by comprising the following steps:

[0068] The material strip to be processed is placed into the material strip conveying and shearing mechanism 1. The conveying component 11 operates to transport the material strip to be processed to the output end of the conveying component 11. The pulling component 22 pulls the material strip to be processed to the set position. Then the pressing component 12 presses the material strip to be processed. The clamping component 32 moves to the position of the material strip to be processed and clamps the material strip to be processed. The shearing component 13 cuts the material strip to be processed to the set length.

[0069] The clamping assembly 32 transports the cut strip to the lower die template 53 in the lower die mechanism 4. The upper die template 631 in the hot pressing mechanism 6 moves downward to hot press the strip. The lower die templates 53 corresponding to the first lower die assembly 44 and / or the second lower die assembly 45 are moved by the lifting and translation movements of the first lower die assembly 44 and / or the second lower die assembly 45, forming the alternation of strips.

[0070] Repeat the above steps, and the strip is woven into shape through multiple alternations and hot pressing.

[0071] The lifting and translational movements of the first lower mold assembly 44 and / or the second lower mold assembly 45 are specifically as follows:

[0072] Case 1: The first power element 42 corresponding to the first lower die assembly 44 drives the first moving plate 51 to separate the lower die template 53 in the first lower die assembly 44 from the hot-pressed material strip. The moving component in the second lower die assembly 45 drives the lower die template 53 in the second lower die assembly 45 to descend. The first power element 42 corresponding to the first lower die assembly 44 drives the first moving plate 51 to move the lower die template 53 in the first lower die assembly 44 to the set position. The moving component in the second lower die assembly 45 drives the lower die template 53 in the second lower die assembly 45 to rise. The two lower die templates 53 re-form a plane, forming an alternating material strip.
