The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.
[0024] like Figures 1 to 4As shown, the present invention provides a foam tape hot pressing forming device, comprising a lower workbench 1 and an upper pressing part 2, the pressing part 2 is installed above the workbench 1 through a mounting frame (not shown in the figure), and the mounting frame and the pressing part 2 are adjusted to a distance between the pressing part 2 and the workbench 1 by a lifting assembly, thereby interfering with the downward movement of the pressing part 2 to pressurize the foam tape above the workbench 1. The lifting assembly belongs to a mature existing technology and will not be described in detail here; the front side of the workbench 1 and the pressing part 2 is provided with an upper and lower matching mechanism for hot pressing the foam tape A hot pressing and conveying assembly for forming is provided, and a conveying assembly for feeding the foam tape into the hot pressing and conveying assembly is provided at one end of the hot pressing and conveying assembly, and a water cooling assembly is provided at the other end of the hot pressing and conveying assembly. In this way, during operation, the foam tape to be processed is conveyed to the hot pressing and conveying assembly through the conveying assembly, and then the hot pressing and conveying assembly between the workbench 1 and the pressurizing part 2 is close to the pressurizing under the action of the lifting assembly, and the foam tape is hot-pressed in an upper and lower manner and conveyed to the side of the water cooling assembly. The hot-pressed foam tape is conveyed to the water cooling assembly for cooling and forming.
[0025] In this embodiment, an embodiment of the hot pressing conveying component is to include two groups of chain rollers 3 symmetrically arranged on the front side of the workbench 1 and the front side of the pressing part 2, each group of chain rollers 3 includes three chain rollers 3 distributed in a regular triangle, and a chain belt 4 is arranged on the outside of each group of chain rollers 3, and the side where the two chain belts 4 are close to each other is horizontally arranged; in this way, the conveying component conveys the foam tape that needs to be processed to the top of the chain belt 4 of the workbench 1, and the pressing part 2 and the chain belt 4 on the front side move downward as a whole, and the foam glue on the chain belt 4 below is pressed. The belt 4 is pressurized, and the workbench 1 and the pressurizing part 2 are both provided with a power component for driving the corresponding group of chain rollers 3 to rotate. The moving directions of the two chain belts 4 approaching each other are consistent, and the two chain belts 4 pressurize and convey the foam tape inside them. At the same time, the workbench 1 and the pressurizing part 2 are both provided with a heating component for uniformly heating the chain belt 4. In this way, the foam tape is heated from the upper and lower sides during the process of the chain belt 4 pressurizing and conveying the foam tape, thereby ensuring that the foam tape is heated evenly during the pressurization process and is heated as a whole.
[0026] In an optional embodiment, the heating assembly includes a conveying pipe 7, which is rotatably mounted on the workbench 1 and the front side of the pressurizing part 2, and the conveying pipe 7 is located at the center of the chain roller 3 of the corresponding group; the chain belt 4 is formed by a plurality of chain blocks 5 hingedly connected end to end, and each chain block 5 has a cavity 8 inside, and three consecutive adjacent chain blocks 5 are connected in an S shape by a connecting pipe 9, such as Figure 3As shown in , the adjacent connecting pipes 9 are used to make the interiors of the cavities 8 of the adjacent chain blocks 5 communicate with each other, and the delivery pipe 7 is connected to the connecting pipes 9 on the upper and lower sides through an elastic connecting pipe. At the same time, the delivery pipe 7 is simultaneously connected to the output end and the input end of the heating medium circulation device. In this way, the heating medium is delivered to the connecting pipe 9 on one side through the delivery pipe 7, and the heating medium passes through the connecting pipe 9 on one side and the chain blocks 5 on both sides of the delivery pipe 7 on this side and then flows back to the heating medium circulation device from the other side of the delivery pipe 7, thereby forming two heating medium circulation heat supplies on both sides of the delivery pipe 7. Figure 5 As shown by the middle arrow, since the conveying pipe 7 is located at the center of each set of chain rollers 3, when each set of chain rollers 3 drives the corresponding chain belt 4 to move, the conveying pipe 7 and the elastic connecting pipe rotate accordingly and maintain the transmission of the heating medium, thereby ensuring that the chain belt 4 is evenly heated, and the two chain belts 4 maintain the hot pressing effect on the foam cotton tape.
[0027] In this embodiment, one embodiment of the elastic connecting pipe is that the upper and lower sides of the delivery pipe 7 are respectively fixedly installed with an elastic bellows 10 between a connecting pipe 9 on the corresponding side, and the interior of the delivery pipe 7 is divided into two cavities by a partition 11, and the two ends of the delivery pipe 7 are respectively connected to the inlet and outlet ends of the heating medium circulation equipment, so that one side of the partition 11 is the input of the heating medium and the other side is the output of the heating medium. At the same time, the upper and lower sides of the delivery pipe 7 are respectively connected to a connecting pipe 9 on the corresponding side through a hose 12, and the hose 12 is respectively connected to the corresponding side. The cavity is connected, so that when the conveying pipe 7 rotates with the movement of the chain belt 4, the internal hose 12 is kept in communication with a connecting pipe 9 on the corresponding side through the elastic bellows 10, and is not affected by the movement of the external chain belt 4. At the same time, the heating medium is transported into the connecting pipe 9 through the hose 12 on one side of the conveying pipe 7, and the heating medium moves to the cavity 8 on both sides through the connecting pipe 9. At the same time, the heating medium flows back to the heating medium circulation equipment from the hose 12 on the other side and the cavity on both sides of the conveying pipe 7, thereby realizing the circulating heat supply of the heating medium in the chain belt 4.
[0028] In this embodiment, the heating medium is preferably high-temperature steam, but may also be other fluid high-temperature gases or high-temperature liquids.
[0029] In an optional embodiment, since the foam tape is pressurized, heated and compressed during the hot pressing and shaping process, its thickness is relatively large when the conveying component conveys the foam tape. Therefore, in order to convey the foam tape, a transition block 13 with a wedge-shaped bottom is installed on the side of the pressurizing part 2 close to the conveying component. The transition block 13 is located on the side of the chain belt 4 close to the conveying component. At the same time, the side of the transition block 13 close to the chain belt 4 is lower than the side close to the conveying component. In this way, in the process of conveying the foam tape from the conveying component to the chain belt 4, the foam tape is first gradually compressed by the transition block 13, and then the foam tape is hot-pressed by the two chain belts 4, and the overall operation is smoother.
[0030] In an optional embodiment, the water cooling component is a water cooling box, which contains cooling water. The foam tape that has been heat-pressed by two chain belts 4 is transported to the water cooling box for shaping and cooling.
[0031] The above-described embodiments of the present invention do not limit the scope of protection of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the claims of the present invention.
