Description

Technical Field

[0001] The present invention relates to the technical field of molding equipment, and more specifically, to a secondary molding machine for preparing high resilience materials using E-TPU particles. Background Art

[0002] E-TPU (foamed thermoplastic polyurethane elastomer) is one of the shoemaking raw materials that has become increasingly popular in recent years. E-TPU is a polymer foam material. The product is oval or nearly circular, with a diameter ranging from 5 to 7 mm.

[0003] The scientific name of the popcorn sole is E-Tpu sole, which is a polymer material sole composed of countless elastic and lightweight TPU foam balls. The shoe not only has good elasticity and shock absorption properties, but also has energy feedback that is ahead of other footwear products in the industry.

[0004] The process used in the production of TPU soles is the TPU foaming process. The so-called "TPU foaming process" is actually like popcorn. TPU is made into granules. You can think of these granules as old corns, and then throw them into a machine, which is similar to a popcorn machine. After high temperature and high pressure, these corns become popcorn. Then, the steam molding process is used to process about 2,000 popcorn granules into the required sole shape. Therefore, TPU soles are also called popcorn soles. In this process, the outermost layer of the foamed particles is slightly melted and adhered into a stable shape. At the same time, the internal pore structure is not affected, so that the formed popcorn sole has many advantages such as soft texture, good elasticity, good cushioning performance, small energy loss under pressure, good durability, and good thermal insulation performance. Its surface presents a granular appearance and texture, which is favored by many consumers.

[0005] In the process of making popcorn soles from TUP foamed particles, the TUP foamed particles need to be heated so that the TUP foamed particles can bond to each other, and then cooled to set; however, the heating of TUP foamed particles has extremely high requirements for temperature. Too high a temperature will cause the TUP foamed particles to shrink and the overall volume to become smaller, which will eventually cause the size of the popcorn sole to shrink and deform during molding. If the temperature is too low, the TUP foamed particles will not be able to bond perfectly, which will greatly affect the structural strength and service life of the popcorn sole. Therefore, the heating temperature must be strictly controlled during the production process.

[0006] At present, the existing popcorn sole forming machines can generally only produce one popcorn sole in one working cycle, and the quality of the formed popcorn soles is inconsistent, resulting in serious waste of materials. At the same time, the production efficiency is low, the production cost is high, and it is difficult to achieve automated production. It cannot meet the current production needs. It is urgent to develop a new type of forming machine to meet the increasing production needs. Summary of the invention

[0068] The following examples are used to describe in detail a secondary molding machine for preparing a high resilience material using E-TPU particles in the present application.

[0069] Embodiment 1:

[0070] like Figure 1-Figure 6 As shown, in this embodiment, a secondary molding machine for preparing a high resilience material using E-TPU particles is proposed, comprising: a frame 1, an upper mold assembly 2 and a lower mold assembly 3;

[0071] Among them, in order to facilitate the installation of the upper mold assembly 2 and the lower mold assembly 3, the frame 1 is divided into an upper mounting frame 11 and a lower mounting frame 12 which are arranged upper and lower; the upper mold assembly 2 is slidably arranged on the upper mounting frame 11 along the vertical direction; the lower mold assembly 3 is slidably arranged on the lower mounting frame 12 along the horizontal direction.

[0072] The lower mold assembly 3 is set to slide in the horizontal direction. On the one hand, it is convenient for the staff to take out the molded elastic material; on the other hand, the lower mold assembly 3 can be set into two groups and arranged at intervals along its sliding direction, so as to achieve the purpose of double workstations. After one group of lower mold assemblies 3 is moved out, the staff can remove the elastic material on it while the other group of lower mold assemblies 3 can be molded with the upper mold assembly 2, thereby realizing continuous production.

[0073] In this embodiment, the molding machine also includes: a first driving component 4, which is used to drive the two groups of lower mold assemblies 3 to move individually so that they are close to or away from the upper mold assembly 2 in the horizontal direction; or is used to drive the two groups of lower mold assemblies 3 to move at the same time, so that one group of lower mold assemblies 3 is close to the upper mold assembly 2 in the horizontal direction, and the other group of lower mold assemblies 3 is away from the upper mold assembly 2; and a second driving component 5, which is used to drive the upper mold assembly 2 to move up and down so that it can close or open the mold with the lower mold assembly 3 located directly below.

[0074] The first driving assembly 4 and the second driving assembly 5 are used to realize the mold closing and mold opening of the upper mold assembly 2 and the lower mold assembly 3.

[0075] Specifically, columns 117 are vertically arranged around the upper mounting frame 11, and the upper mold assembly 2 is slidably arranged on each column 117 through a linear bearing. The first driving assembly 4 includes: a hydraulic system, which is composed of a plurality of hydraulic cylinders, one end of the hydraulic cylinder is mounted on the upper mounting frame 11, and the other end is connected to the upper mold assembly 2. Under the action of the hydraulic system, the upper mold assembly 2 can be smoothly moved up and down.

[0076] There is a horizontally arranged slide rail on the lower mounting frame 12, and two sets of lower mold assemblies 3 are slidably arranged on the slide rail. The second driving assembly 5 can adopt a servo ball screw module, and the ball screw module drives the lower mold assembly 3 to perform linear motion.

[0077] In this embodiment, the upper mold assembly 2 includes: an upper mold frame 21, which is disposed on the upper mounting frame 11; and at least one upper mold (not shown in the figure) which is disposed on the mounting cavity of the upper mold frame 21;

[0078] The lower mold assembly 3 includes: a lower mold frame 31, which is arranged on the lower mounting frame 12; and at least one lower mold (not shown in the figure) which is arranged on the mounting cavity of the lower mold frame 31;

[0079] After the upper mold frame 21 and the lower mold frame 31 are butt-jointed, the upper mold and the lower mold are clamped.

[0080] The opposite end faces of the upper mold and the lower mold each have a cavity for forming the elastic material. After the upper mold and the lower mold are closed, the two cavities are combined into a whole, and the elastic material is formed in the two cavities.

[0081] It should be noted that, in the present embodiment, the number of upper dies and lower dies is set to 6, but the number is not limited and can be set according to actual conditions.

[0082] It should be noted that the resilient material referred to above is not limited to popcorn soles, but may also be other items.

[0083] It should be noted that the frame 1 further includes: a pedestrian walkway 13 arranged on the front and rear sides of the lower mounting frame 12 to facilitate the staff to check the status of the molding machine.

[0084] Embodiment 2:

[0085] This embodiment is a further improvement made on the basis of the first embodiment.

[0086] like Figure 2 and Figure 3 As shown, in this embodiment, a first horizontal beam 111 and a first vertical beam 112 are arranged horizontally on both sides of the upper mounting frame 11. The upper end of the first vertical beam 112 is connected to the first horizontal beam 111, and the lower end thereof extends downward.

[0087] The molding machine further includes: two groups of first feeding assemblies 6 for respectively feeding materials to the cavities on the two groups of lower molds; the two groups of first feeding assemblies 6 each include: a first feeding tank 61, for storing raw materials and conveying the raw materials to the cavity of the lower mold, on which a first feeding port 611 and a first discharging port 612 are provided; and a material channel, the inlet end of which is connected to the material storage chamber, and the outlet end is connected to the first feeding port 611 end of the first feeding tank 61 through a first hose;

[0088] The first cross beam 111 and the first vertical beam 112 are hollow structures, which are interconnected. A first port 113 is provided on the first cross beam 111 . The inner cavities of the first cross beam 111 and the first vertical beam 112 form a material channel, and the first hose is connected to the first port 113 .

[0089] After the upper mold and the lower mold are closed, the raw material needs to be transported into the cavity, so a first feeding assembly 6 is also provided. The material is sucked into the first feeding tank 61 through the material channel and the first hose, and then the first feeding tank 61 transports the material into the cavity of the lower mold.

[0090] Since two groups of lower mold assemblies 3 are provided and the lower mold assemblies 3 can move, the structure of the first feeding assembly 6 for conveying raw materials to the lower mold needs to be very complicated. Specifically, the conveying pipeline is intricately arranged, that is, it needs to be set very long, at least to ensure that no interference occurs when the lower mold assembly 3 moves.

[0091] Based on this, a first horizontal beam 111 and a first vertical beam 112 are provided, and the material channel is formed in the first horizontal beam 111 and the first vertical beam 112. That is to say, the first horizontal beam 111 and the first vertical beam 112 are arranged into a pipeline structure, which can realize the transportation of materials and also serve as an installation bracket of the first feeding tank 61. This arrangement can effectively reduce the complexity of the conveying pipeline of the first feeding assembly 6.

[0092] Embodiment three:

[0093] This embodiment is a further improvement made on the basis of the second embodiment.

[0094] like Figure 2 and Figure 3 As shown, in this embodiment, since the vertical pipe between the first loading tank 61 and the lower mold is long in itself, and the lower mold assembly 3 needs to move, in order to avoid the pipe between the first loading tank 61 and the lower mold being too long and easily damaged after being bent for a long time. For this reason, the first loading tank 61 and the lower mold assembly 3 are set as a whole, that is, the first loading tank 61 and the lower mold assembly 3 can move synchronously, so that the pipe between the first loading tank 61 and the lower mold can be prevented from being too long and will not move.

[0095] Specifically, a slide rail is provided on the first cross beam 111, and the first loading tank 61 is slidably provided on the slide rail; wherein, a connecting beam is provided between the first loading tank 61 and the lower mold frame 31, and when the lower mold frame 31 moves, the first loading tank 61 moves synchronously therewith.

[0096] This arrangement can effectively reduce the length of the pipeline between the first loading tank 61 and the lower mold, and is also convenient for layout.

[0097] Specifically, a discharge tray is provided at the bottom of the first feeding tank 61, and the first discharge port 612 is a plurality of discharge holes located on the discharge tray; the first feeding assembly 6 also includes: a hose rack 62, which is provided on the lower mold frame 31, and a pipe joint 621 is provided on the hose rack 62; a second hose (not shown in the figure), one end of which is connected to the upper end of the pipe joint 621 on the hose rack 62, and the other end is connected to the discharge hole; a third hose (not shown in the figure), one end of which is connected to the lower end of the pipe joint 621, and the other end is connected to the material gun; and a first material gun (not shown in the figure), which is used to transport the material in the first feeding tank 61 from the second hose and the third hose to the chamber of the lower mold;

[0098] There are multiple pipe joints 621, second hoses, third hoses and material guns, which are connected in sequence, and each material gun delivers material to each cavity on the lower mold.

[0099] The material is discharged from the discharge hole at the bottom of the first feeding tank 61, and finally transported to the cavity of the lower mold through the material gun. In order to prevent the pipe between the first feeding tank 61 and the lower mold from being too bent and affecting the material transportation, a hose rack 62 is provided, and a plurality of pipe joints 621 are installed on the hose rack 62. The hose rack 62 is located at the side end of the lower mold frame 31 and is close to the first feeding tank 61. After that, the second hose and the third hose can be connected to the upper and lower ends of the pipe joint 621 of the hose rack 62 respectively, and then connected to the discharge hole at the bottom of a feeding tank and the material gun.

[0100] It should be noted that the first feeding tank 61 adopts a negative pressure method to suck the material, and then transports the material to the lower mold in a pulse manner.

[0101] It should be noted that the material gun connected to the first feeding tank 61 passes upward from the bottom of the lower mold frame 31 and extends into the cavity of the lower mold.

[0102] Embodiment 4:

[0103] This embodiment is a further improvement made on the basis of the third embodiment.

[0104] like Figure 1-Figure 3 As shown, in this embodiment, in order to enable the material to be fully filled in the cavities of the upper mold and the lower mold, in addition to the first feeding component 6 for conveying material to the lower mold, a second feeding component 7 for conveying material to the upper mold is also provided.

[0105] Specifically, a second port 114 is provided on the first beam 111;

[0106] The molding machine also includes: a second feeding assembly 7 for feeding materials into the cavity in the upper mold; the second feeding assembly 7 includes: a second feeding tank 71, which is arranged on the upper mounting frame 11, and the second feeding tank 71 is provided with a second feeding port 711 and a second feeding port 712; a fourth hose (not shown in the figure), one end of which is connected to the second port 114 on the first beam 111, and the other end is connected to the second feeding port 711; and a second material gun, which is connected to the second feeding port 712 through a fifth hose.

[0107] In this embodiment, since the material channel is formed in the first cross beam 111 and the first vertical beam 112, the feeding pipeline of the second feeding tank 71 can be set more simply, that is, a second port 114 is opened on the first cross beam 111, and then the second port 114 is connected to the second feeding port 711 on the second feeding tank 71 through the fourth hose. When the second feeding tank 71 is loaded, the material flows from the storage chamber to the first vertical beam 112, then flows to the first cross beam 111, and then flows to the fourth hose through the second port 114, and finally reaches the second feeding tank 71.

[0108] It should be noted that the structure of the second feeding tank 71 is the same as that of the first feeding tank 61, and both adopt a negative pressure method to suck the material and then transport the material to the lower mold in a pulse manner.

[0109] It should be noted that the material gun connected to the second feeding tank 71 passes downward from the top of the upper mold frame 21 and extends into the cavity of the upper mold.

[0110] Embodiment five:

[0111] This embodiment is a further improvement made on the basis of the third embodiment or the fourth embodiment.

[0112] like Figure 1-Figure 3 , Figure 5 As shown, in this embodiment, after the upper mold and the lower mold are closed and the material is injected into the cavities of the two, the material particles need to be heated so that adjacent material particles can fuse together and form the shape of the cavity. For this purpose, a steam heating component 8 is also provided.

[0113] Specifically, there are also second horizontal beams 115 arranged horizontally and second vertical beams 116 arranged vertically on both sides of the upper mounting frame 11. The upper ends of the second vertical beams 116 are connected to the second horizontal beams 115, and the lower ends thereof extend downward.

[0114] The molding machine further includes: a steam heating assembly 8, which is used to transport steam to the upper mold and the lower mold to heat the material; the steam heating assembly 8 includes: a steam main pipe 81, which is used to transport steam; a first steam diverter pipe 82, whose inlet end is connected to the steam main pipe 81, and whose outlet end is connected to the chamber of the upper mold through a first steam hose; a second steam diverter pipe 83, whose inlet end is connected to the steam main pipe 81; a steam channel, whose inlet end is connected to the outlet end of the second steam diverter pipe 83, and whose outlet end is connected to the chamber of the lower mold through a second steam hose;

[0115] Among them, the second cross beam 115 and the second vertical beam 116 are hollow structures, the two are interconnected, and a third port is opened on the second cross beam 115. The inner cavities of the second cross beam 115 and the second vertical beam 116 form a steam channel, and the inlet end of the second steam hose is connected to the third port.

[0116] The steam heating component 8 uses water vapor to heat the material particles, causing secondary foaming and fusing adjacent material particles together. In order to heat the material particles in the upper mold and the lower mold evenly, it is necessary to transport steam to the upper mold and the lower mold at the same time. Based on the first crossbeam 111 and the first vertical beam 112, a second crossbeam 115 and a second vertical beam 116 are provided, and then the inner cavities of the two are formed into a steam channel, so that only the first steam shunt pipe 82, the second steam shunt pipe 83, the first steam hose, and the second steam hose need to be provided to form a complete heating channel. This setting greatly reduces the use of pipelines and the complexity of the layout, and improves the installation efficiency.

[0117] It should be noted that the steam main pipe 81, the first steam diversion pipe 82, the second steam diversion pipe 83, the second cross beam 115, and the second vertical beam 116 are all made of metal materials; the first steam hose and the second steam hose are made of soft materials that can be bent.

[0118] In this embodiment, since the first loading tank 61 is not stable when it is disposed on the first beam 111 , it is also connected to the second beam 115 .

[0119] Specifically, a slide rail is provided on the second cross beam 115, and sliding brackets 613 are provided on both sides of the outer wall of the first loading tank 61. The first loading tank 61 is slidably provided on the first cross beam 111 and the second cross beam 115 through two sliding brackets 613. Under the action of the first cross beam 111 and the second cross beam 115, the first loading tank 61 can smoothly move synchronously with the lower mold assembly 3.

[0120] It should be noted that

[0121] Embodiment six:

[0122] This embodiment is a further improvement made on the basis of the fifth embodiment.

[0123] like Figure 1-Figure 6 As shown, in this embodiment, after the steam heats the upper mold and the lower mold, and after a period of time, the material particles in the cavity between the upper mold and the lower mold will be fully fused together. In order to enable them to be quickly shaped, a cooling component 9 is required to be provided to quickly shape the material particles in the upper mold and the lower mold.

[0124] Specifically, it also includes: a cooling component 9, which is used to transport coolant to the upper mold and the lower mold to cool and shape the material; the cooling component 9 includes: a coolant main pipe 91, which is used to transport coolant; a first coolant shunt pipe 92, whose inlet end is connected to the coolant main pipe 91, and the outlet end is connected to the upper mold through the first coolant hose; a second coolant shunt pipe, whose inlet end is connected to the coolant main pipe 91, and the outlet end is connected to the lower mold through the second coolant hose; and a discharge pipe, which is used to discharge the coolant in the upper mold and the lower mold to the outside.

[0125] In order to control production costs, the cooling assembly 9 can use water as the coolant. The coolant main pipe 91 is connected to the water inlet pipe. After the water enters the coolant main pipe 91, it will flow out from the first coolant shunt pipe 92 and the second coolant shunt pipe, and then flow to the upper mold and the lower mold respectively, and finally be discharged from the discharge pipe, so as to achieve rapid cooling of the upper mold and the lower mold, and then quickly cool and shape the material particles.

[0126] It should be noted that the drain pipe is divided into a main drain pipe 94 and a first branch drain pipe 95 and a second branch drain pipe 96 connected to the main drain pipe 94, wherein the other end of the first branch drain pipe 95 is connected to the drain port on the lower mold, and the second branch drain pipe 96 is connected to the drain port on the upper mold, and the coolant in the upper mold and the lower mold is respectively discharged to the main drain pipe 94 through the first branch drain pipe 95 and the second branch drain pipe 96, and finally discharged from the main drain pipe 94.

[0127] Embodiment seven:

[0128] This embodiment is a further improvement made on the basis of the embodiment.

[0129] like Figure 5 As shown, in this embodiment, since there will be a small amount of water in the upper mold and the lower mold during the next processing, the temperature of the steam will be low when the steam heats the material particles in the upper mold and the lower mold, that is, the temperature will be conducted by the water in the upper mold and the lower mold, making it difficult for the material particles to fully fuse. Of course, if the steam temperature is directly increased, the steam temperature in the upper mold and the lower mold will be difficult to control. If it is too high, the material particles will decompose or carbonize. If it is too low, it will be difficult for the material particles to fully fuse. Therefore, the steam heating component 8 is further optimized.

[0130] Specifically, the steam heating component 8 also includes: a third steam diversion pipe, whose inlet end is connected to the steam main pipe 81 and whose outlet end is connected to the first coolant diversion pipe 92; and a fourth steam diversion pipe 85, whose inlet end is connected to the steam main pipe 81 and whose outlet end is connected to the second coolant diversion pipe 93.

[0131] Among them, when the steam main pipe 81 transports steam, the first steam diversion pipe 82, the second steam diversion pipe 83, the third steam diversion pipe, and the fourth steam diversion pipe 85 transport steam simultaneously. The first steam diversion pipe 82 and the second steam diversion pipe 83 transport steam to the cavity of the upper mold and the cavity of the lower mold respectively, and directly act on the material; the third steam diversion pipe and the fourth steam diversion pipe 85 transport steam to the upper mold and the lower mold respectively, and after the coolant in the upper mold and the lower mold is squeezed outward, the upper mold and the lower mold are heated.

[0132] When the steam main pipe 81 transports steam, the coolant in the upper mold and the lower mold can be quickly moved toward the drain pipe direction and discharged from the drain pipe through the third steam diversion pipe and the fourth steam diversion pipe 85. Subsequently, the steam heats the upper mold and the lower mold, thereby keeping the material particles in the cavities of the upper mold and the lower mold warm, effectively improving the fusion efficiency between the material particles.

[0133] It should be noted that, in order to facilitate installation and reduce parts, the third steam diversion pipe is connected to the first steam diversion pipe 82 and the first coolant diversion pipe 92, so that the third steam diversion pipe forms a conduit 84, and then the conduit 84 is externally connected to the first coolant hose and the first steam hose.

[0134] The embodiments of the present disclosure have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
