Abstract

This utility model discloses a high-efficiency hot-pressing and shaping device for composite material three-dimensional fabrics, relating to the field of textile machinery technology. It includes a base, a carrier column rotatably connected to the base via bearings, a gear fixedly sleeved on the outside of the carrier column, a fixing block fixed on the base, a first hydraulic cylinder mounted on the fixing block, a carrier block fixedly mounted at the output end of the first hydraulic cylinder, a rack fixed on the carrier block, and the rack meshing with the gear. A support plate is fixed to the top of the carrier column. By using the first hydraulic cylinder to pull the rack back and forth, and through the meshing of the rack and gear, the carrier column can be pulled to rotate the support plate, causing the two heat-insulated platforms at both ends of the support plate to exchange positions. The area for picking up and placing the three-dimensional fabric corresponds to the two heat-insulated platforms, respectively. In this way, the heat-pressing component is far from the area for picking up and placing the three-dimensional fabric, effectively preventing workers from being burned by the heat-pressing component when handling the three-dimensional fabric.

Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and in particular to a high-efficiency hot pressing and shaping device for composite material three-dimensional fabrics. Background Technology

[0002] In the hot pressing and shaping process of composite preforms (such as laminates), it is often necessary to cyclically hot press and shape the fiber cloth layers, and the requirements for fabric surface accuracy (flatness error ≤0.2mm), thickness dimensional accuracy (≤0.2%) and thickness uniformity are relatively high.

[0003] Common hot press setting devices work by moving the position of the hot press components to alternately hot press and set three-dimensional fabrics placed on two adjacent heat-insulated platforms, thereby improving the efficiency of hot press processing of three-dimensional fabrics. During this process, workers need to manually pick up and put down the three-dimensional fabrics after hot press setting. However, the two heat-insulated platforms are close together, and workers are prone to being burned by the hot press components while picking up and putting down the three-dimensional fabrics, which increases the safety hazard. In addition, the three-dimensional fabrics after hot press setting are not easy to cool and set quickly, which affects the efficiency of hot press setting of three-dimensional fabrics. Utility Model Content

[0004] The purpose of this application is to provide a high-efficiency hot pressing and shaping device for composite material three-dimensional fabrics, so as to solve the problems mentioned in the background art, where workers are easily burned by the hot pressing components when manually picking up and placing the three-dimensional fabrics after hot pressing and shaping, due to the close distance between the two heat-insulating platforms, which increases the safety hazard, and the three-dimensional fabrics after hot pressing are not easy to cool and shape quickly, which affects the processing efficiency of three-dimensional fabrics.

[0005] To achieve the above objectives, this application provides the following technical solution: a high-efficiency hot-pressing and shaping device for composite three-dimensional fabrics, comprising a base, a carrier column rotatably connected to the base via bearings, a gear fixedly sleeved on the outside of the carrier column, a fixing block fixed on the base, a first hydraulic cylinder mounted on the fixing block, a carrier block fixedly mounted on the output end of the first hydraulic cylinder, a rack fixed on the carrier block, the rack meshing with the gear, a support plate fixed at the top of the carrier column, two first U-shaped blocks fixed on the upper surface of the support plate, a first carrier tube rotatably connected between the opposing inner walls of the first U-shaped blocks via pins, a connecting block fixed on the outer wall of the first carrier tube, a heat-insulating platform fixed at the top of the connecting block, a traction assembly between the support plate and the heat-insulating platform, the traction assembly being used to traction the heat-insulating platform to rotate around the first carrier tube, and a hot-pressing assembly and two air-cooling assemblies mounted on the base, the hot-pressing assembly being used for hot-pressing the three-dimensional fabric, and the air-cooling assemblies being used for cooling the three-dimensional fabric after hot pressing.

[0006] Furthermore, the traction assembly includes two second U-shaped blocks, one of which is fixedly mounted on the support plate and the other is fixedly mounted on the heat-insulating platform. A second carrier tube is rotatably connected between the relative inner walls of the second U-shaped blocks by a pin, and a second hydraulic cylinder is fixedly installed between the two second carrier tubes.

[0007] Furthermore, the hot pressing assembly includes a support plate, which is fixedly mounted on the base, and a third hydraulic cylinder is fixedly mounted on the top of the support plate.

[0008] Furthermore, a cover is fixedly installed at the output end of the third hydraulic cylinder, an insulation layer is fixed at the bottom of the cover, a hot press plate is fixed at the bottom of the insulation layer, and a plurality of heating rods are provided in the hot press plate.

[0009] Furthermore, the air-cooling assembly includes a fourth hydraulic cylinder, which is fixedly mounted on the base, and a fixing plate is fixedly mounted on the output end of the fourth hydraulic cylinder.

[0010] Furthermore, a bellows is fixed to one side of the fixed plate, several air guide pipes are fixed through the bottom of the bellows, a fan is installed on the top of the bellows, and the air outlet of the fan is connected to the bellows.

[0011] Furthermore, a flow divider is provided inside the air box, and a filter screen is provided at the air inlet of the fan.

[0012] In summary, the technical effects and advantages of this utility model are as follows:

[0013] 1. In this utility model, the first hydraulic cylinder pulls the rack back and forth. With the meshing of the rack and gear, the carrier column can be pulled to rotate the pallet, so that the two heat-insulating platforms located at both ends of the pallet can exchange positions. The area for picking up and placing the three-dimensional fabric corresponds to the two heat-insulating platforms respectively. In this way, the heat-insulating platform is far away from the area for picking up and placing the three-dimensional fabric, which can effectively prevent workers from being burned by the heat-insulating platform when picking up and placing the three-dimensional fabric. The second hydraulic cylinder can push the heat-insulating platform to rotate around the first carrier tube and adjust the angle of the heat-insulating platform so that the three-dimensional fabric after heat-pressing and shaping on the heat-insulating platform can slide down automatically, saving the workers' physical exertion.

[0014] 2. In this utility model, the height of the air guide pipe is adjusted by the fourth hydraulic cylinder, so that the air blown into the air box by the fan can be discharged along several air guide pipes, which helps the three-dimensional fabric after hot pressing to cool and set quickly, which can speed up the setting efficiency of the three-dimensional fabric and thus improve the processing efficiency of the three-dimensional fabric to a certain extent. The use of the diverter plate allows the air blown into the air box by the fan to be dispersed, which can better cool the three-dimensional fabric after hot pressing. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example: Reference Figure 1-6The device for efficient hot pressing and shaping of composite three-dimensional fabrics includes a base 1, a carrier column 2 rotatably connected to the base 1 via bearings, a gear 7 fixedly sleeved on the outside of the carrier column 2, a fixing block 3 fixed on the base 1, a first hydraulic cylinder 4 mounted on the fixing block 3, a carrier block 5 fixedly mounted on the output end of the first hydraulic cylinder 4, a rack 6 fixed on the carrier block 5, the rack 6 meshing with the gear 7, a support plate 8 fixed at the top of the carrier column 2, two first U-shaped blocks 9 fixed on the upper surface of the support plate 8, a first carrier tube 10 rotatably connected between the relative inner walls of the first U-shaped blocks 9 via pins, a connecting block 11 fixed on the outer wall of the first carrier tube 10, a heat-insulating platform 12 fixed at the top of the connecting block 11, a traction assembly between the support plate 8 and the heat-insulating platform 12, the traction assembly being used to traction the heat-insulating platform 12 to rotate around the first carrier tube 10, and a hot pressing assembly and two air-cooling assemblies mounted on the base 1. The hot pressing assembly is used for hot pressing of the three-dimensional fabric, and the air-cooling assemblies are used for cooling the three-dimensional fabric after hot pressing.

[0025] The first hydraulic cylinder 4 pulls the rack 6 back and forth. With the rack 6 and gear 7 meshing with each other, the carrier column 2 can be pulled to drive the pallet 8 to rotate, so that the two heat-insulating platforms 12 located at both ends of the pallet 8 can exchange positions. The area for picking up and placing three-dimensional fabrics corresponds to the two heat-insulating platforms 12 respectively. In this way, the heat-pressing component is far away from the area for picking up and placing three-dimensional fabrics, which can effectively prevent workers from being burned by the heat-pressing component when picking up and placing three-dimensional fabrics.

[0026] The traction assembly includes two second U-shaped blocks 13, one of which is fixedly mounted on the support plate 8 and the other is fixedly mounted on the heat-insulating platform 12. The inner walls of the two second U-shaped blocks 13 are rotatably connected by a pin, and a second hydraulic cylinder 15 is fixedly installed between the two second loading pipes 14.

[0027] The second hydraulic cylinder 15 can be used to push the heat insulation table 12 to rotate around the first carrier tube 10, and adjust the angle of the heat insulation table 12 so that the three-dimensional fabric after heat pressing and shaping on the heat insulation table 12 can slide down automatically, saving the workers' physical exertion.

[0028] The hot pressing assembly includes a support plate 16, which is fixedly installed on the base 1. A third hydraulic cylinder 17 is fixedly installed on the top of the support plate 16. A cover 18 is fixedly installed at the output end of the third hydraulic cylinder 17. An insulation layer 19 is fixedly installed at the bottom of the cover 18. A hot pressing plate 20 is fixedly installed at the bottom of the insulation layer 19. Multiple heating rods 21 are provided in the hot pressing plate 20.

[0029] The third hydraulic cylinder 17 is used to push the hot press plate 20 down, so that the hot press plate 20 can perform hot pressing and shaping treatment on the three-dimensional fabric placed on the heat insulation table 12 below.

[0030] The air-cooled component includes a fourth hydraulic cylinder 22, which is fixedly mounted on the base 1. A fixing plate 23 is fixedly mounted on the output end of the fourth hydraulic cylinder 22. A wind box 24 is fixed on one side of the fixing plate 23. Multiple air guide pipes 25 are fixedly fixed through the bottom of the wind box 24. A fan 26 is installed on the top of the wind box 24. The air outlet of the fan 26 is connected to the wind box 24. A filter screen is installed at the air inlet of the fan 26. A diverter plate 27 is installed inside the wind box 24.

[0031] The height of the air guide pipe 25 is adjusted by the fourth hydraulic cylinder 22, so that the air blown into the air box 24 by the fan 26 can be discharged along multiple air guide pipes 25, which helps the hot-pressed three-dimensional fabric to cool and set quickly, which can speed up the setting efficiency of the three-dimensional fabric and thus improve the processing efficiency of the three-dimensional fabric to a certain extent. The use of the diverter plate 27 allows the air blown into the air box 24 by the fan 26 to be dispersed, which can better cool the hot-pressed three-dimensional fabric.

[0032] The working principle of this practical application is as follows:

[0033] In use, the worker stands near the heat-insulating platform 12, away from the hot-pressing assembly, and places the three-dimensional fabric to be heat-pressed on the heat-insulating platform 12. The worker then extends the first hydraulic cylinder 4, causing it to pull the rack 6 to move. With the help of the meshing of the rack 6 and the gear 7, the worker can rotate the heat-insulating platform 12 180°, so that the heat-insulating platform 12 below the hot-pressing assembly is exchanged with the heat-insulating platform 12 at the worker's position. The three-dimensional fabric is moved to the bottom of the hot-pressing assembly. The worker then takes out the next three-dimensional fabric and places it on the heat-insulating platform 12 that has just been transferred. The worker then operates the third hydraulic cylinder 17 to push the hot-pressing plate 20 down, and the heating rod 21 heats the hot-pressing plate 20, so that the hot-pressing plate 20 heats the three-dimensional fabric placed on the heat-insulating platform 12. After the heat pressing is completed, the worker operates the third hydraulic cylinder 17 to move the hot-pressing plate 20 up to the starting position, and then operates the first hydraulic cylinder 4 to retract, so that the rack 6 pulls the two heat-insulating platforms 12 to exchange positions again, and uses the hot-pressing assembly to start a new round of work.

[0034] During the rotation of the hot-pressed 3D fabric, the fourth hydraulic cylinder 22 pulls the air duct 25 down to a position 5cm from the top of the 3D fabric according to its height. The blower 26 blows air into the air box 24, causing the airflow to be directed out along multiple air ducts 25. This airflow cools the hot-pressed 3D fabric, accelerating its cooling and shaping. When the cooled 3D fabric returns to the worker's position with the heat-insulating table 12, it does not need to be removed by the worker. The second hydraulic cylinder 15 is simply extended to push the heat-insulating table 12 to rotate and tilt around the first carrier pipe 10. The 3D fabric then slides down the heat-insulating table 12 by its own weight to unload itself. Afterward, the second hydraulic cylinder 15 pulls the heat-insulating table 12 back to a horizontal position, and the worker can place the 3D fabric to be hot-pressed and shaped on the heat-insulating table 12.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
