Description

Technical Field

[0001] This utility model relates to the field of UD fabric processing technology, and in particular to a high-temperature pressing device for multi-layer UD fabric. Background Technology

[0002] UD fabric, or unidirectional fabric, refers to a textile with a large amount of woven yarn or untwisted roving in one direction (usually the warp, but also the weft) and only a small amount, usually fine yarn, in the other direction. As a result, the entire strength of the fabric is in one direction. It is commonly used in the production of glass fiber and various bulletproof yarns (Dyneema yarn, carbon fiber yarn, aramid yarn).

[0003] Existing technologies, such as the multi-layer UD fabric high-temperature pressing device disclosed in CN113002107A, include a device body containing a pre-pressing device and a bearing device. The pre-pressing device is located on the top surface of the bearing device and includes a top cover, a hydraulic device, and slide rods. There are four sets of slide rods, with the bottom end of each set located on the top surface of the bearing device. There are multiple sets of hydraulic devices, with the bottom end of each set located on the top surface of the upper pressure plate. Each of the four corners of the upper pressure plate has a collar, the middle of which is movably fitted onto the outer surface of the slide rod. Users can perform a complete heat-sealing and pressing operation on the multi-layer UD fabric after preheating, improving the cleanliness of the fabric during operation and avoiding wrinkles and incomplete pressing. However, the above technology cannot place multi-layer UD fabrics of different thicknesses between the worktable and the pulleys, resulting in high-temperature pressing only on multi-layer UD fabrics of fixed sizes. It is not applicable to multi-layer UD fabrics of different thicknesses, and its scope of application is limited. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing technologies can only perform high-temperature pressing on multi-layer UD fabrics of fixed thickness, and to propose a high-temperature pressing device for multi-layer UD fabrics.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-temperature pressing device for multi-layer UD fabric includes a base plate. A protective shell is fixedly installed on the upper part of the base plate. The outer wall of the protective shell has a placement groove for placing multi-layer UD fabric into the protective shell. Four rectangularly distributed sliding rods are fixedly installed on the base plate relative to the inside of the protective shell. The top ends of the sliding rods are fixedly connected to the upper inner wall of the protective shell, and each of the four sliding rods has a slidable collar. A worktable for placing multi-layer UD fabric is fixedly connected to the inner wall of the four collars. A driving mechanism for moving the worktable up and down is provided between the lower part of the worktable and the base plate. The driving mechanism includes a drive motor fixedly installed on the base plate and four parallel fixed plates. A transverse bevel gear is fixedly installed at the output end of the drive motor. The gear has a first vertical bevel gear and a second vertical bevel gear at both ends. A first lead screw is rotatably mounted on two fixed plates on the left side of the drive motor, and a second lead screw is rotatably mounted on two fixed plates on the right side of the drive motor. Both the first and second lead screws have movable blocks fitted on their outer walls. A connecting rod is rotatably mounted on the upper part of the movable block via a pin. A connecting seat is rotatably mounted on the top of the connecting rod via a pin. The horizontal bevel gear meshes with the first and second vertical bevel gears respectively. Nuts are fitted on the outer walls of both the first and second lead screws. The outer walls of the two nuts are fixedly connected to the inner walls of the two movable blocks. The first and second lead screws have reverse threads. The upper wall of the connecting seat is fixedly connected to the lower wall of the worktable.

[0007] To better achieve the above objectives, the present invention adopts a further technical solution: four L-shaped fixing rods are fixedly installed on the upper wall of the base plate at equal intervals, and pressure plates for pressing the edges of the multi-layer UD fabric on the worktable are fixedly installed on the fixing rods.

[0008] To better achieve the above objectives, the present invention adopts a further technical solution: two hydraulic cylinders are fixedly installed on the upper wall of the protective shell, and a top plate for high-temperature pressing of the multi-layer UD cloth placed on the workbench is fixedly installed at the bottom of each of the two hydraulic cylinders.

[0009] To better achieve the above objectives, the present invention adopts a further technical solution: the top plate has a hollow structure in the middle, a heat insulation plate is provided inside the top plate, and a heating wire is provided on the bottom surface of the heat insulation plate.

[0010] To better achieve the above objectives, the present invention adopts a further technical solution: the workbench has a hollow structure inside, and multiple sets of hot pressing holes are opened at the top of the workbench.

[0011] The advantages of this utility model are: by pushing the connecting seat with two connecting rods, the worktable is moved upward, so that the pressure plate fixes the two sides of the multi-layer UD fabric on the worktable. Then, the multi-layer UD fabric is subjected to high-temperature pressing by the downward movement of the top plate. It is suitable for high-temperature pressing of multi-layer UD fabrics of different sizes and has a wide range of applications. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Reference Figures 1-6As shown, a high-temperature pressing device for multi-layer UD fabric includes a base plate 1. A protective shell 2 is fixedly installed on the upper part of the base plate 1. The outer wall of the protective shell 2 has a placement groove 3 for placing multi-layer UD fabric into the protective shell 2. Four rectangularly distributed slide rods 17 are fixedly installed on the base plate 1 relative to the inner wall of the protective shell 2. The top of the slide rods 17 is fixedly connected to the upper inner wall of the protective shell 2, and each of the four slide rods 17 has a collar 16 slidably provided on its outer wall. A worktable 14 for placing multi-layer UD fabric is fixedly connected to the inner wall of the four collars 16. A drive mechanism for driving the worktable 14 to move up and down is provided between the lower part of the worktable 14 and the base plate 1. When the connecting seat 13 pushes the worktable 14 to move upward, the collars 16 are sleeved on the slide rods 17 to position the worktable 14 and prevent it from shifting. The drive mechanism includes a drive motor 4 fixedly installed on the base plate 1 and four parallel fixed plates 5. A horizontal bevel gear 6 is fixedly installed at the output end of the drive motor 4. A first vertical bevel gear 7 and a second vertical bevel gear 9 are provided at both ends of the horizontal bevel gear 6. A first lead screw 8 is rotatably installed on the two fixed plates 5 on the left side of the drive motor 4, and a second lead screw 10 is rotatably installed on the two fixed plates 5 on the right side of the drive motor 4. Movable blocks 11 are sleeved on the outer walls of the first lead screw 8 and the second lead screw 10. A connecting rod 12 is rotatably installed on the upper part of the movable block 11 through a pin. A connecting seat 13 is rotatably installed on the top of the connecting rod 12 through a pin. The horizontal bevel gear 6 meshes with the first vertical bevel gear 7 and the second vertical bevel gear 9 respectively. Nuts are sleeved on the outer walls of the first lead screw 8 and the second lead screw 10. The outer walls of the two nuts are fixedly connected to the inner walls of the two movable blocks 11. The first lead screw 8 and the second lead screw 10 are provided with reverse threads. The upper wall of the connecting seat 13 is fixedly connected to the lower wall of the worktable 14.

[0021] Four L-shaped fixing rods 18 are fixedly installed on the upper wall of the base plate 1 at equal intervals. The fixing rods 18 are fixedly installed with pressure plates 19 for pressing the edges of the multi-layer UD fabric on the worktable 14.

[0022] Two hydraulic cylinders 20 are fixedly installed on the upper wall of the protective shell 2. The bottom of each hydraulic cylinder 20 is fixedly installed with a top plate 21 for high-temperature pressing of the multi-layer UD cloth placed on the workbench 14.

[0023] The top plate 21 has a hollow structure in the middle, and a heat insulation plate 22 is installed inside the top plate 21. A heating wire 23 is installed on the bottom surface of the heat insulation plate 22, and the bottom of the heat insulation plate 22 is coated with heat insulation paint to prevent the heating wire 23 from overheating and causing the multi-layer UD fabric to melt due to excessive heat.

[0024] The worktable 14 has a hollow interior and multiple sets of hot pressing holes 15 are opened at the top of the worktable 14.

[0025] This invention involves placing multiple layers of UD fabric onto a workbench 14 through a slot 3 on the outer wall of the protective shell 2. Then, by activating the drive motor 4, the horizontal bevel gear 6 rotates clockwise. This rotation of the horizontal bevel gear 6 causes the first vertical bevel gear 7 to rotate upwards, driving the first lead screw 8 to rotate clockwise on the fixed plate 5. This, in turn, causes the horizontal bevel gear 6 to drive the second vertical bevel gear 9 to rotate downwards, driving the second lead screw 10 to rotate clockwise on the fixed plate 5. The fixed plate 5 rotates counterclockwise, causing the movable blocks 11 on the first lead screw 8 and the second lead screw 10 to move in opposite directions toward the drive motor 4. This causes the two movable blocks 11 to push the lower end of the connecting rod 12 to move laterally, and the upper end of the connecting rod 12 to push the connecting seat 13 to move upward. This pushes the two sides of the multi-layer UD fabric on the worktable 14 to adhere to the bottom of the pressure plate 19, fixing the position of the multi-layer UD fabric. Then, by opening the hydraulic cylinder 20, the hydraulic cylinder 20 pushes the top plate 21 to move downward, and the heating wire 23 inside the top plate 21 presses the multi-layer UD fabric at high temperature.
