Description

Technical Field

[0001] The invention relates to the technical field of injection molding, in particular to a high-flexibility TPEE preparation raw material mixing and perfusion device. Background Art

[0002] In the existing TPEE (thermoplastic elastomer polyether ester) raw material preparation process, traditional raw material mixing and infusion equipment usually uses a single screw extrusion or gravity infusion method to convey and mix the materials. Specifically, the traditional device mainly includes a single screw conveyor barrel, a fixed mixing chamber and an ordinary gravity infusion structure. During the mixing process, the material is pushed into the mixing chamber by the rotation of the single screw, and then mixed by a simple stirring component, and finally enters the infusion channel to complete the infusion process. The structure of this type of technical solution is relatively simple, but when faced with high-viscosity and high-demand TPEE materials, its conveying, mixing and infusion effects are relatively limited, which can easily lead to material waste, uneven mixing and low efficiency.

[0003] Although the traditional technical solution can complete basic transportation and mixing, the following defects are exposed in actual production: The traditional single-screw extruder is prone to unstable material flow due to the lack of precise control during the conveying process. There are problems of material loss and uneven distribution during the infusion process, which reduces production efficiency and the stability of product quality. The mixing chamber of the traditional device usually relies on simple stirring components to complete the mixing of materials, but due to the lack of effective diversion and confluence design, the mixing effect of materials in the mixing chamber is poor, especially when the proportion of multiple raw materials is strictly required, which is easy to cause uneven mixing and directly affect the performance of TPEE.

[0004] Traditional technical solutions fail to effectively optimize the material flow path during material transportation and mixing. The material flow is prone to stagnation or turbulence during transportation, and cannot achieve fast and efficient mixing and infusion. In addition, the instability of the material flow may also lead to increased energy consumption during equipment operation, further affecting production efficiency.

[0005] In response to the above problems, there is an urgent need for a technical solution that can achieve efficient mixing, precise infusion and improved delivery stability, so as to overcome the defects in traditional technologies and improve the efficiency and product quality of the high-flexibility TPEE preparation process. Summary of the invention

[0006] The present invention aims to solve the technical problems existing in the prior art or related technologies such as uneven material mixing, low perfusion accuracy and insufficient conveying efficiency, and thus provides a high-flexibility TPEE preparation raw material mixing and perfusion device, thereby achieving efficient mixing, precise perfusion and high efficiency and stability of material conveying.

[0007] To achieve the above purpose, the technical solution adopted by the present invention is: A high-flexibility TPEE preparation raw material mixing and perfusion device, comprising a conveying cylinder, a mixing assembly and a manifold; a reduction motor is fixedly installed at one end of the conveying cylinder, and a screw rod connected to the output end of the reduction motor is rotatably installed inside the conveying cylinder, and a feed end tube is provided on the top surface of the conveying cylinder; a first drive box and a second drive box are fixedly installed at the bottom of the mixing assembly, and both ends of the mixing assembly are respectively connected to the conveying cylinder and the manifold, and a diverter disk is rotatably installed at one end of the inner cavity of the conveying cylinder.

[0008] The mixing assembly includes a mixing chamber, a diverter and a feeder, and the diverter and the feeder are both rotatably installed on the inner side of the mixing chamber; a first gear ring and a second gear ring are rotatably installed on both sides of the mixing chamber, and the surfaces of the diverter and the feeder are respectively engaged with the output ends of the first drive box and the second drive box; a plurality of conical diversion structures are arranged on the inner side of the mixing chamber to realize the diversion and convergence of materials in the mixing chamber.

[0009] The diverter includes an inner ring cylinder, outer rotating blades and a first transmission tooth. One end of the inner ring cylinder is fixedly connected to the outer rotating blades, and the first transmission tooth is in transmission engagement with the inner side of the first gear ring. The feeder includes a diverter cone cylinder, an inner rotating shaft and a second transmission tooth. One end of the inner rotating shaft passes through the inner ring cylinder and is fixedly connected to the diverter cone cylinder, and the other end is in transmission engagement with the second gear ring through the second transmission tooth.

[0010] The inner and outer sides of the inner ring cylinder and the diverter cone cylinder form an inner flow channel and an outer flow channel. The materials move through the intersection and confluence of the inner and outer flow channels, thereby achieving efficient mixing of the raw materials and entering the confluence pipe.

[0011] In a preferred example, the present invention can be further configured as follows: The outer periphery of the spiral rod is in sliding contact with the inner side of the conveying cylinder, and the conveying movement of the material in the conveying cylinder is realized by driving the reduction motor.

[0012] The number of the diverters, feeders and conical diverter structures in the mixing chamber is several groups, and they are evenly distributed on the periphery of the axis of the screw rod in the circumferential direction. Several diverters and feeders are synchronously driven by the gear ring to further improve the mixing and conveying efficiency.

[0013] The inner ring cylinder and the diversion cone cylinder both adopt a conical design, wherein the cross-section of the inner ring cylinder is a water drop cone, and an inner flow channel and an outer flow channel are respectively arranged on the inner and outer sides thereof. The outer flow channel realizes material transportation by rotating the outer rotating blade, and the inner flow channel realizes material transportation by rotating the inner rotating shaft.

[0014] A diverter ring is arranged on the inner side of the inner ring cylinder, and a plurality of overflow holes are provided on the surface of the diverter ring for diverting part of the material in the inner flow channel to the outer flow channel, thereby achieving material flow balance and uniform mixing between the inner and outer flow channels.

[0015] The diverter cone of the feeder is a symmetrical conical ring, the outer periphery of which is in sliding contact with the inner side of the inner ring, and the conical spiral structure simulates the fluid movement characteristics of the Tesla valve to achieve acceleration and stabilization of the material flow during the conveying process.

[0016] The first drive box and the second drive box have the same structure, both comprising a motor and a driving tooth fixed to the output end of the motor, and the synchronous reverse rotation drive of the guider and the feeder is realized through the engagement of the driving tooth with the gear ring.

[0017] Through the above technical scheme, the present invention can effectively solve the problems of uneven material mixing, inaccurate perfusion and low conveying efficiency in the prior art, greatly improve the production quality and efficiency of high-flexibility TPEE preparation, and is suitable for the industrial production needs of high-performance engineering materials.

[0018] The beneficial effects achieved by the present invention are: 1. In the present invention, the coaxial counter-rotation design of the guider and the feeder can realize efficient transportation and precise pouring of materials in the mixing chamber, avoiding the problems of material loss and uneven flow rate in traditional pouring devices.

[0019] 2. In the present invention, when the screw rotates to transport the material, the material flow is diverted to each inner side and mixed on the inner side of the confluence pipe. Furthermore, through the conical diversion structure of the inner ring cylinder and the diversion cone cylinder, the material is mixed between the inner ring cylinder and the diversion cone cylinder, which can achieve efficient mixing of the raw materials and ensure mixing uniformity, thereby significantly improving the production quality of preparing high-flexibility TPEE.

[0020] 3. In the present invention, the conical spiral design of the inner ring cylinder and the diverter cone cylinder is used to simulate the fluid movement effect of the Tesla valve, which can accelerate the material flow during the conveying and mixing process, further improve the perfusion efficiency, and ensure the stability of the material flow.

DETAILED DESCRIPTION

[0023] To make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in combination with specific implementations and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0024] It is to be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention. Example 1

[0025] The following is combined with Figure 1-Figure 7 A high-flexibility TPEE preparation raw material mixing and infusion device provided in some embodiments of the present invention is described.

[0026] This embodiment provides a high-flexibility TPEE raw material mixing and perfusion device, such as Figures 1 to 7 As shown, it includes a delivery cylinder 100 , a mixing assembly 200 and a manifold 300 .

[0027] A reduction motor 110 is fixedly mounted at one end of the conveying cylinder 100 , and the output end of the reduction motor is connected to the screw rod 102 in the conveying cylinder, and the outer periphery of the screw rod is in sliding contact with the inner wall of the conveying cylinder.

[0028] A feed end pipe 120 is provided on the top surface of the conveying cylinder, through which the TPEE raw material is conveyed to the interior of the conveying cylinder. Driven by the reduction motor 110, the material moves axially along the screw rod 102 to the mixing assembly 200.

[0029] The mixing assembly includes a mixing chamber 210, a guide diverter 220 and a feeder 230. The mixing chamber 210 is connected to the conveying cylinder 100 and the manifold 300 through its two ends. A first drive box 130 and a second drive box 140 are fixedly installed at the bottom of the mixing chamber, and the two drive the guide diverter 220 and the feeder 230 respectively. The mixing chamber 210 is rotatably installed on one side of the conveying cylinder 100 and is coaxially arranged. The end of the screw rod 102 is fixedly connected to the end of the mixing chamber 210, so as to realize the synchronous rotation of the mixing chamber 210 and the screw rod 102.

[0030] The guide divider 220 includes an inner ring cylinder 221, an outer rotating vane 222 and a first transmission tooth 223. An inner flow channel and an outer flow channel are respectively arranged on both sides of the inner ring cylinder 221, and the first transmission tooth 223 meshes with the first gear ring 240 to realize rotation.

[0031] The feeder 230 includes a flow dividing cone 231, an inner rotating shaft 232 and a second transmission tooth 233. The flow dividing cone 231 is a conical ring, and its outer periphery is in sliding contact with the inner side of the inner ring cylinder 221, and the second transmission tooth 233 is meshed with the second gear ring 250 to achieve synchronous reverse rotation.

[0032] Material mixing and conveying process: The materials are diverted from the conveying cylinder 100 at the diverter plate 101 and enter the mixing chamber 210 , and are transported and mixed through the inner flow channel and the outer flow channel respectively under the rotation of the diverter 220 and the feeder 230 .

[0033] The intersection of the inner ring cylinder 221 and the diverter cone cylinder 231 forms the diversion and confluence of the materials. In this process, the materials are evenly mixed and enter the next process stage through the confluence pipe 300. Example 2

[0034] In order to further optimize the perfusion efficiency and mixing effect, this embodiment provides an improved structure of embodiment 1.

[0035] Optimized design of guider and feeder: The outer rotating blade 222 of the guide device 220 is a multi-stage spiral blade, and the spiral angle of each blade gradually increases, so that the material is compressed and pushed step by step during the mixing process, thereby enhancing the uniformity of material mixing.

[0036] The inner rotating shaft 232 of the feeder 230 is designed as a variable cross-section structure, and its outer circumference matches the shape of the flow channel inside the inner ring cylinder 221, ensuring that there are no dead angles during the material transportation process and improving the transportation efficiency.

[0037] Configuration of multiple groups of mixed components: The guide divider 220 and the feeder 230 in the mixing chamber 210 are configured into multiple groups, and the multiple groups of mixing components are arranged in parallel along the axis direction of the mixing chamber. After multiple conveying processes, the materials enter the confluence pipe 300 to be converged and mixed again.

[0038] The gap between the outer rotating blades 222 of each group of mixing components and the diverter cone 231 is gradually reduced, so that the material forms a compression effect during the multi-stage mixing process, thereby improving the mixing uniformity and the pouring accuracy.

[0039] Optimization of flow diversion and confluence: A plurality of overflow holes 224 are added in the diverter ring provided on the inner ring tube 221. These overflow holes divert part of the material in the inner flow channel to the outer flow channel, and merge with the material of the outer rotating blade 222 to achieve a more complete mixing effect.

[0040] A spiral inner and outer flow passage intersection area is formed between the inner ring cylinder 221 and the diverter cone cylinder 231 . The intersection area generates turbulence when the inner and outer flow passages intersect, thereby further improving the mixing efficiency.

[0041] Automation control: Control modules are installed in the first driving box 130 and the second driving box 140 respectively. By adjusting the rotation speed of the guide 220 and the feeder 230, precise control of the material conveying speed and mixing intensity is achieved to ensure adaptability to different raw material ratios.

[0042] Advantageous Effects of Embodiments Through the above two embodiments, the present invention can significantly improve the mixing uniformity and infusion accuracy of high-flexibility TPEE raw materials and achieve efficient production. Embodiment 1 focuses on the realization of basic functions and is suitable for ordinary production needs; Embodiment 2 further improves the performance and applicability of the equipment through structural optimization and automatic control, meeting higher requirements of industrial production scenarios.

[0043] The working principle and use process of the present invention: The present invention realizes efficient mixing and precise infusion of high-flexibility TPEE raw materials through the coordinated work of the conveying cylinder, mixing assembly and manifold. The main working principle of the present invention is as follows: Material conveying: The screw rod 102 inside the conveying barrel 100 rotates under the drive of the reduction motor 110, pushing the TPEE raw material entering from the feed end pipe 120 to move along the axis of the conveying barrel. The thrust generated by the rotation of the screw rod and the sliding contact of the inner wall of the conveying barrel ensure that the material is smooth and unblocked during the conveying process.

[0044] Diversion and confluence of the mixing assembly: After the raw materials are diverted by the diverter plate 101 and enter the mixing chamber 210, they are diverted to the inner flow channel and the outer flow channel by the coaxial counter-rotation of the diverter 220 and the feeder 230. The outer rotating blade 222 of the diverter 220 transports part of the materials in the outer flow channel, and the inner rotating shaft 232 of the feeder 230 transports the other part of the materials in the inner flow channel.

[0045] The diverted materials are re-converged through the inner and outer flow channels at the intersection of the inner ring cylinder 221 and the diverter cone cylinder 231, forming a multiple diversion and mixing cycle, thereby achieving efficient mixing.

[0046] The flow dividing ring and the overflow hole 224 on the inner ring tube 221 further guide part of the material in the inner flow channel to the outer flow channel, and merge with the material in the outer flow channel to form a spiral turbulent effect and enhance the mixing uniformity.

[0047] Fluid acceleration of Tesla valve effect: The conical structure of the inner ring cylinder 221 and the diverter cone cylinder 231 simulates the fluid motion characteristics of the Tesla valve. Through the interweaving of the inner and outer flow channels, the material always maintains flow stability and increases the speed during the conveying and mixing process, avoiding the material blockage problem in traditional injection equipment.

[0048] Precise infusion: The mixed raw materials enter the next process link through the manifold 300 at the lower end of the mixing chamber 210. The design of the manifold ensures the uniformity and stability of the material flow, achieves precise infusion, and avoids material waste or uneven infusion.

[0049] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
