Abstract
Description
Technical Field
[0001] This utility model belongs to the field of semi-cured sheet transportation technology, specifically a roll-shaped semi-cured sheet transportation device. Background Technology
[0002] Prepreg rolls are a type of reinforcing fiber material pre-impregnated with resin (usually thermosetting or thermoplastic resin) in a partially cured state. This material is typically supplied in rolls for easy storage, transportation, and subsequent processing. It is widely used in aerospace, automotive, sporting goods, and printed circuit board (PCB) manufacturing, and is known for its precise fiber-to-resin ratio, high strength, lightweight, and excellent mechanical properties. Because the resin is in a semi-cured state, some types of prepreg rolls require refrigeration or freezing to extend their shelf life.
[0003] For example, the utility model patent with announcement number CN221162872U discloses a roll-shaped prepreg transport device, including: a frame and a fixing component. The bottom of the frame is provided with a pulley system. The fixing component includes a first fixing rod and a second fixing rod. The first fixing rod and the second fixing rod are connected to the frame and are arranged at intervals along the width direction of the frame. A fixing groove for fixing the roll-shaped prepreg is formed between the first fixing rod and the second fixing rod. The embodiment of this utility model provides a roll-shaped prepreg transport device that clamps the roll-shaped prepreg in the fixing groove on the frame. During acceleration or deceleration, the position of the roll-shaped prepreg is fixed and it is not easy to roll. This can prevent the roll-shaped prepreg from rolling or falling off during transportation, which is not only conducive to ensuring the smooth progress of transportation.
[0004] However, in actual use, it was found that the device uses the first fixing rod and the second fixing rod to limit the roll of semi-cured sheet, which makes it easy for the frame to carry and transport.
[0005] However, this device is limited in two ways. First, the transport capacity is restricted by the number of rolls of prepreg that the fixed groove can hold, making it difficult to meet the needs of large-scale continuous transport. Second, it relies solely on two fixed rods for positioning and lacks a constraint structure for the ends of the rolls of prepreg. When the length of the rolls of prepreg is short, they are prone to sliding left and right between the first and second fixed rods during transport, which greatly affects the transport stability and cannot reliably guarantee the transport status of the rolls of prepreg. Therefore, a rolls of prepreg transport device is provided. Utility Model Content
[0006] The purpose of this invention is to provide a roll-shaped prepreg transport device in order to solve the problems mentioned above.
[0007] The technical solution adopted by this utility model is as follows: A roll-shaped semi-cured sheet transport device includes a transport frame. The transport frame has multiple placement frames inside, and a fixed support plate is fixedly installed near the center of each placement frame. Multiple V-shaped limiting plates (first type) are evenly spaced arrayed on the top surface of each fixed support plate. Two movable support plates are arranged inside each placement frame on the side of the fixed support plate, and multiple V-shaped limiting plates (second type) corresponding to the first type are fixedly installed on the top surface of each of the two movable support plates. The placement frame has... A connecting limiting assembly connected to the movable support plate includes a limiting baffle fixedly installed on the side of the V-shaped limiting plate two away from the V-shaped limiting plate one. Two bidirectional ball screws are threadedly connected to one side of the movable support plate, and each of the two bidirectional ball screws has two threaded sections with opposite directions of rotation. A bearing is fixedly installed on the inner side wall of the placement frame. One end of the bidirectional ball screw is fixedly installed in the middle of the bearing. A synchronous pulley is fixedly installed on the outer surface of the end of the bidirectional ball screw away from the bearing. A synchronous belt is movably sleeved on the outer surface of the synchronous pulley.
[0008] In a preferred embodiment, the connecting limiting component includes a sliding groove and a limiting slider. Multiple sliding grooves are symmetrically opened on the inner sidewall of the placement frame. Limiting sliders adapted to the sliding grooves are fixedly installed on the left and right sides of the movable support plate, and the end of the limiting slider away from the movable support plate is inserted into the inside of the sliding groove.
[0009] In a preferred embodiment, the inner sidewall of the transport frame is symmetrically provided with grooves, and the left and right sides of the placement frame are respectively fixedly installed with protrusions corresponding to the grooves. The protrusions are inserted into the inside of the grooves, and the inner sidewall of the groove is threadedly connected to the front of the placement frame with a limit bolt.
[0010] In a preferred embodiment, flexible rubber pads are fixedly installed inside both the first V-shaped limiting plate and the second V-shaped limiting plate, and a scale is fixedly installed on the top surface of the placement frame.
[0011] In a preferred embodiment, the bottom surface of the fixed support plate is provided with a U-shaped hole, and one end of the bidirectional ball screw passes through the interior of the U-shaped hole.
[0012] In a preferred embodiment, a push handle is fixedly installed on the rear side of the transport frame, a connecting plate is fixedly installed on the rear side of the transport frame near the bottom, and multiple casters are rotatably connected to the bottom surface of the transport frame near the corners.
[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0014] 1. In this utility model, due to the adoption of the above-mentioned solution, the user first rotates the bidirectional ball screw. Under the action of the synchronous pulley and synchronous belt, the two screws rotate synchronously, driving the moving support plate to move in the slide groove through the limiting slider. Combined with the scale, the V-shaped limiting plate two is adjusted to the appropriate position. The middle part of the rolled semi-cured sheet is placed on the V-shaped limiting plate one, and the two ends are placed on the V-shaped limiting plate two respectively. The moving support plate is finely adjusted to cooperate with the V-shaped limiting plate one for clamping. The flexible rubber pad prevents damage, and the limiting baffle prevents slippage. This device achieves layered placement through multiple pull-out placement frames, increasing the single transport capacity and facilitating loading and unloading. The V-shaped limiting plates one and two cooperate with the limiting baffle to adapt to different sizes and effectively limit movement, preventing rotation and forward and backward movement during transportation.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0022] refer to Figures 1-5As shown, a roll-shaped prepreg transport device includes a transport frame 1. A push handle 18 is fixedly installed on the rear side of the transport frame 1, and a connecting plate 19 is fixedly installed on the rear side of the transport frame 1 near the bottom. Multiple casters 20 are rotatably connected to the bottom surface of the transport frame 1 near the corners. The push handle 18 facilitates the push of the transport frame 1 by the staff, and the casters 20 enable the transport frame 1 to move flexibly, making it easy to transport the roll-shaped prepreg to a designated location. The connecting plate 19 has a connecting hole at its top, which allows it to be connected to a traction transport trolley within the factory area by a pin, thus improving the adaptability and flexibility of the transport frame 1.
[0023] refer to Figures 1-5 As shown, the transport frame 1 has multiple placement frames 2 inside, and each placement frame 2 has a fixed support plate 3 fixedly installed near the center. Multiple V-shaped limiting plates 4 are installed at equal intervals on the top surface of the fixed support plate 3. Through the multiple placement frames 2, roll-shaped semi-cured sheets can be placed in layers, and each layer can hold roll-shaped semi-cured sheets of the same size and type, thus increasing the transport capacity. The fixed support plates 3 provide a stable installation base for the V-shaped limiting plates 4, which can limit the roll-shaped semi-cured sheets, prevent them from rolling during transportation, and improve stability.
[0024] refer to Figures 1-5 As shown, the inner sidewall of the transport frame 1 is symmetrically provided with grooves 13. The left and right sides of the placement frame 2 are respectively fixedly installed with protrusions 14 corresponding to the grooves 13. The protrusions 14 are inserted into the inside of the grooves 13. The inner sidewall of the grooves 13 is located in front of the placement frame 2 and is threaded with limit bolts 15. The front and top of the transport frame 1 are open. The placement frame 2 is connected to the transport frame 1 by the protrusions 14 inserted into the grooves 13. This facilitates the installation and disassembly of the placement frame 2. The limit bolts 15 can limit and fix the placement frame 2 to prevent it from slipping off the transport frame 1 during transportation. When it is necessary to pull out the middle and lower layer placement frame 2 to place the roll semi-cured sheet, simply unscrew the limit bolts 15.
[0025] refer to Figures 1-5As shown, inside the placement frame 2, two movable support plates 5 are provided on the side of the fixed support plate 3. Multiple V-shaped limiting plates 6, corresponding to V-shaped limiting plates 4, are fixedly installed on the top surface of each movable support plate 5. Flexible rubber pads 16 are fixedly installed inside both V-shaped limiting plates 4 and V-shaped limiting plates 6. A scale is fixedly installed on the top surface of the placement frame 2. A connecting limiting component 12 connected to the movable support plates 5 is provided inside the placement frame 2. A limiting baffle 7 is fixedly installed on the side of the V-shaped limiting plate 6 away from the V-shaped limiting plate 4. Through the set V-shaped... The second limiting plate 6 works in conjunction with the first V-shaped limiting plate 4 to clamp and limit the roll of prepreg. The flexible rubber pad 16 prevents the roll of prepreg from being damaged by direct contact with the limiting plate, thus improving the protection of the roll of prepreg. The scale allows workers to easily adjust the position of the moving support plate 5 according to the size of the roll of prepreg. The connecting limiting component 12 ensures the stability of the moving support plate 5 during movement. The limiting baffle 7 limits the end of the roll of prepreg, further preventing it from slipping.
[0026] refer to Figures 1-5 As shown, the connecting limiting component 12 includes a slide groove 1201 and a limiting slider 1202. Multiple slide grooves 1201 are symmetrically opened on the inner side wall of the placement frame 2. Limiting sliders 1202 adapted to the slide grooves 1201 are fixedly installed on the left and right sides of the movable support plate 5 respectively. The end of the limiting slider 1202 away from the movable support plate 5 is inserted into the interior of the slide groove 1201. By sliding the limiting slider 1202 in the slide groove 1201, the movement of the movable support plate 5 can be guided and limited, ensuring that the movable support plate 5 can move back and forth smoothly and avoiding deviation during the movement.
[0027] refer to Figures 1-5As shown, two bidirectional ball screws 8 are threadedly connected to one side of the movable support plate 5, and each of the two bidirectional ball screws 8 has two threaded sections with opposite directions of rotation. A U-shaped hole 17 is opened on the bottom surface of the fixed support plate 3, and one end of the bidirectional ball screw 8 passes through the interior of the U-shaped hole 17. A bearing 9 is fixedly installed on the inner side wall of the placement frame 2, and one end of the bidirectional ball screw 8 is fixedly installed in the middle of the bearing 9. A synchronous pulley 10 is fixedly installed on the outer surface of the end of the bidirectional ball screw 8 away from the bearing 9, and a synchronous belt 11 is movably sleeved on the outer surface of the synchronous pulley 10. An internal threaded cylinder is fixedly installed through one side of the movable support plate 5, and the bidirectional ball screw 8 is threadedly connected to the interior of the internal threaded cylinder. Two reverse threads allow the two movable support plates 5 to move simultaneously toward or in opposite directions, facilitating the adjustment of the distance between the V-shaped limiting plate 2 6 and the V-shaped limiting plate 4 to accommodate rolls of prepreg of different sizes. The synchronous pulley 10 and synchronous belt 11 ensure that the two bidirectional ball screws 8 rotate synchronously, making the movement of the movable support plates 5 more synchronous and stable. The bearing 9 reduces the friction when the bidirectional ball screws 8 rotate. The U-shaped hole 17 provides installation space for the bidirectional ball screws 8. One end of one of the two bidirectional ball screws 8 extends to the outside of the placement frame 2 and is equipped with a handwheel, making it easy for personnel to turn the handwheel to drive the bidirectional ball screw 8 to rotate.
[0028] The implementation principle of this utility model's roll-shaped prepreg transportation device is as follows: The user first moves the transport frame 1 to the loading position by pushing the handle 18 and the caster wheel 20. Then, according to the size of the roll-shaped prepreg to be transported, the user rotates the handwheel at one end of one of the bidirectional ball screws 8. Under the transmission action of the synchronous pulley 10 and the synchronous belt 11, the two bidirectional ball screws 8 rotate synchronously. Since the two sections of the bidirectional ball screw 8 have opposite thread directions, they can drive the two movable support plates 5 to move towards or in opposite directions within the slide groove 1201 via the limiting slider 1202. At this time... Personnel can use the scale on the top surface of the placement frame 2 to adjust the V-shaped limiting plate 2 6 to a position that matches the rolled semi-cured sheet. Then, personnel place the rolled semi-cured sheet near the middle inside the V-shaped limiting plate 1 4, with its two ends correspondingly placed inside the V-shaped limiting plate 2 6. Then, personnel can fine-tune the moving support plate 5 so that the V-shaped limiting plate 1 4 and the V-shaped limiting plate 2 6 cooperate to achieve stable clamping of the rolled semi-cured sheet. The flexible rubber pad 16 can prevent the rolled semi-cured sheet from directly contacting the limiting plate and causing damage, while the limiting baffle 7 can prevent the rolled semi-cured sheet from slipping during transportation.
[0029] This device uses multiple placement frames 2 that can be pulled out from inside the transport frame 1 to achieve layered placement of rolls of semi-cured sheets of different sizes and types. This not only increases the quantity transported at one time, but also facilitates loading and unloading operations for personnel in the middle and lower placement frames 2. At the same time, the cooperation of V-shaped limiting plate 1 4, V-shaped limiting plate 2 6 and limiting baffle 7 can accommodate rolls of semi-cured sheets of different sizes and form an effective constraint on them, preventing rotation and forward and backward movement during transportation and improving transportation stability.
