Description

Technical Field

[0001] This utility model relates to the technical field of chemical fiber filament storage equipment, and in particular to a special pallet for transporting chemical fiber filament rolls. Background Technology

[0002] Special pallets for transporting chemical fiber filament rolls are transport carrying tools designed specifically for chemical fiber filament roll products. The pallets are made of high-strength composite materials or high-quality steel, and their structure is precisely adapted to the cylindrical characteristics of the filament rolls. The pallet surface is equipped with arc-shaped grooves or adjustable fixing devices, which can securely hold filament rolls of different specifications, preventing the rolls from shifting, wearing out, or the filaments from loosening due to bumps and collisions during transportation.

[0003] A search revealed Chinese Patent Publication No. CN117734235A, which discloses a processing technology and structure for a double-diameter paper tube. The process includes the following steps: S1. The inner and outer tubes are processed and formed separately: This can be done using traditional paper tube forming equipment; S2. The outer and inner tubes are precisely cut: After processing, the outer and inner tubes are cut off to obtain the required lengths; S3. The inner and outer tubes are dried: They are placed in a drying oven. During drying, the inner tube gradually shrinks. Through multiple experiments, the moisture content in the inner tube is controlled at 0%, and the moisture content in the outer tube is controlled at 14%. At this point, the inner tube shrinks to a diameter smaller than the inner diameter of the outer tube; S4. The inner tube is pressed into the outer tube; S5. The inner and outer tubes are meshed and connected. The purpose of this application is to significantly improve the production efficiency of this double-diameter paper tube to effectively ensure the daily processing and production of paper tubes. However, in actual use, the transportation method is to place the wire roll vertically on the pallet to prevent the roll from rolling. When the paper tube is placed vertically, the wire wrapped on the surface of the paper tube will slide axially due to the influence of gravity, especially for the relatively smooth wire, making the overall transportation inconvenient. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a special pallet for transporting chemical fiber filament rolls, which aims to improve the problem in the prior art where the filaments wrapped around the surface of the paper tube slide axially due to gravity when the paper tube is placed vertically.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A special pallet for transporting chemical fiber filament rolls includes a base and two uprights. The top of the base is provided with a support mechanism and a fixing mechanism. The outer walls of the two uprights are provided with multiple weight-reducing grooves. The top of the base is provided with a reinforcing mechanism and an installation mechanism. The support mechanism includes multiple reinforcing vertical rods (first type), the bottoms of which are fixedly connected to the top of the base. The tops of the multiple reinforcing vertical rods (first type) are all fixedly connected to the same base plate. The top of the base plate is fixedly connected to multiple bottom blocks. The tops of the multiple bottom blocks are fixedly connected to multiple reinforcing horizontal rods. The tops of the multiple reinforcing horizontal rods are fixedly connected to multiple reinforcing vertical rods (second type). The tops of the multiple reinforcing vertical rods (second type) are fixedly connected to a main plate. The top of the main plate is provided with a surrounding plate. Multiple connecting strips are fixedly connected to the front and rear sides of the bottom of the surrounding plate. The top of the base is provided with a connecting assembly.

[0006] The above technical solution involves reinforcing the vertical support plate to increase the height of the pallet, allowing for ventilation at the bottom. Forklift holes are formed between the base plate, bottom blocks, and main plate to facilitate the transfer of the device using a forklift. The weight of the wire coil is distributed through the cross-force structure of the vertical and horizontal bars to prevent deformation of the main plate. At the same time, the surrounding plate can prevent displacement when the wire coil is on the surface of the main plate, while the spring sheet can buffer vibration.

[0007] As a further description of the above technical solution: The fixing mechanism includes multiple sliders, the tops of which are fixedly connected to the bottoms of two upright plates. The top left and right sides of the main plate have sliding grooves, and the tops of the multiple sliders have slots. The inner walls of the multiple slots are slidably connected to elastic fixing rods. The outer walls of the two elastic fixing rods have mounting grooves on their front and rear sides. The inner walls of the multiple mounting grooves are fixedly connected to springs, and the inner walls of the multiple mounting grooves are fixedly connected to guide rods. The opposite sides of the multiple guide rods are fixedly connected to fixing blocks. The outer walls of the two elastic fixing rods each have two fixing grooves on their front and rear sides. The outer wall of the enclosure is provided with reinforcing components.

[0008] The above technical solution involves sliding the slider into the groove, and after reaching the predetermined position, sliding the elastic fixing rod into the slot and the groove. Then, the tension of the spring is used to make the fixing block pass through the fixing groove and slide to connect with the groove in the groove, thereby fixing the upright plate to the main plate.

[0009] As a further description of the above technical solution: The strengthening mechanism includes multiple reinforcing ribs, the outer walls of which are fixedly connected to the inner walls of multiple weight-reducing grooves, and multiple limiting grooves are provided on the inner walls of the two upright plates.

[0010] The above technical solution involves reinforcing the upright plate with reinforcing ribs, while the limiting groove is used to install the reinforcing ribs.

[0011] As a further description of the above technical solution: The installation mechanism includes two rollers, with the opposite sides of the two rollers slidably connected to adjacent sides of two vertical plates, and slots are provided on adjacent sides of the two vertical plates.

[0012] The above technical solution involves sliding the spools into the slots, thereby limiting the position of the yarn roll by the two spools.

[0013] As a further description of the above technical solution: The connecting assembly includes multiple bolts, the outer walls of which are threaded to the opposite side of multiple connecting strips, and the outer walls of which are slidably connected to spring pieces. The opposite side of the multiple connecting strips is provided with threaded grooves.

[0014] The above technical solution involves inserting bolt one into the threaded groove and using spring clips for shock absorption, thereby fixing the enclosure plate to the reinforcing vertical rod two.

[0015] As a further description of the above technical solution: The reinforcement component includes multiple bolts, the outer walls of which are threaded to the left and right sides of the outer wall of the enclosure, and nuts are threaded to the outer walls of the multiple bolts.

[0016] The above technical solution involves fixing the enclosure and the uprights by inserting two bolts through the outer wall and the uprights of the enclosure, and then connecting a nut at the end of the outer wall.

[0017] As a further description of the above technical solution: A rubber pad is fixedly connected to the bottom of the base, and multiple anti-slip strips are fixedly connected to the bottom of the rubber pad.

[0018] The above technical solution reduces vibration by using rubber pads, while anti-slip strips increase friction.

[0019] As a further description of the above technical solution: Each of the two uprights is fixedly connected to a sponge pad on one of its adjacent sides, and the top left and right sides of the bottom plate are fixedly connected to two load-bearing reinforcing ribs.

[0020] The above technical solution reduces vibration between the sponge pad and the wire roll, while the load-bearing reinforcing ribs increase the structural strength between the base plate and the main plate in the support mechanism.

[0021] In summary, this utility model has the following beneficial effects: 1. In this utility model, the components are assembled in layers to form a stable support structure, which raises the operating height and makes it easier to load and unload the chemical fiber filament rolls. The cross-force structure of the vertical and horizontal bars can distribute the weight and prevent the tray from deforming. At the same time, the side plate can block displacement when the filament roll is on the main board surface, and the spring can buffer vibration. The transverse loading prevents the filament from sliding axially, which comprehensively improves the stability of transportation, protects the quality of the filament, and is convenient to operate and durable in structure.

[0022] 2. In this utility model, the slider slides along the slide groove to guide the installation of the upright plate. Then, the slider is initially fixed by mechanical locking formed by the elastic fixing rod, spring and fixing block. Finally, it is reinforced by the connection between the bolt and nut. This not only realizes the quick positioning and fixing of the upright plate and enhances the device's anti-loosening ability, but also allows for the replacement of different upright plates according to actual needs to adapt to different sizes of wire rolls, thus expanding the applicability of the device and improving its practicality.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides a special pallet for transporting chemical fiber filament rolls, including a base 1 and two upright plates 2. The top of the base 1 is provided with a support mechanism 3 for supporting chemical fiber filament rolls. The top of the base 1 is provided with a fixing mechanism 4 for fixing the upright plates 2 to the main plate 306. The outer walls of the two upright plates 2 are provided with multiple weight-reducing grooves 5 for reducing the weight of the device. The top of the base 1 is provided with a reinforcing mechanism 6 for enhancing the structural strength of the upright plates 2. The top of the base 1 is provided with an installation mechanism 7 for installing a roll 701, thereby fixing the chemical fiber filament rolls. The support mechanism 3 includes multiple reinforcing vertical rods 301, which increase the height of the mounting mechanism 7. The bottoms of the multiple reinforcing vertical rods 301 are fixedly connected to the top of the base 1. The tops of the multiple reinforcing vertical rods 301 are all fixedly connected to the same base plate 302. The top of the base plate 302 is fixedly connected to multiple bottom blocks 303, which increase the height of the mounting mechanism 7. The tops of the multiple bottom blocks 303 are fixedly connected to multiple reinforcing horizontal rods 304. The tops of the multiple reinforcing horizontal rods 304 are fixedly connected to multiple reinforcing vertical rods 305. The reinforcing horizontal rods 304 and reinforcing vertical rods 305 are used to increase the height of the mounting mechanism 7. The overall structural strength is ensured while maintaining the height of the main board 306 to prevent the bottom support block 303 from tilting when the object is heavy. The top of the multiple reinforcing vertical bars 305 are all fixedly connected to the main board 306. The main board 306 is the top plate-shaped component. The top of the main board 306 is provided with a surrounding plate 307. The surrounding plate 307 is used to prevent the chemical fiber filament rolls from rolling to the ground when they fall. Multiple connecting strips 308 are fixedly connected to the front and back sides of the bottom of the surrounding plate 307. The connecting strips 308 facilitate the connection between the surrounding plate 307 and the reinforcing vertical bars 305. The top of the base 1 is provided with a connecting component 309, which is used to connect the surrounding plate 307 and the reinforcing vertical bars 305. The connecting assembly 309 includes a plurality of bolts 3091, the outer walls of which are threaded to the opposite side of a plurality of connecting bars 308, and the outer walls of which are slidably connected to spring pieces 3092, which are used to reduce vibration. The opposite side of the plurality of connecting bars 308 is provided with threaded grooves 3093, and the bolts 3091 are threaded to the threaded grooves 3093. Specifically, the base 1 is placed on a flat surface. The bottom of the first reinforcing vertical rod 301 is fixed to the top of the base 1, and the top is connected to the base plate 302. The overall height is raised by the first reinforcing vertical rod 301. Multiple bottom blocks 303 are installed on the top of the base plate 302 to further increase the height. The second reinforcing horizontal rod 304 is then fixed to the top of the bottom blocks 303. The second reinforcing vertical rod 305 is connected above the second reinforcing horizontal rod 304. The structural strength is enhanced by the cooperation of the second reinforcing horizontal rod 304 and the second reinforcing vertical rod 305. The main board 306 is fixed to the top of the second reinforcing vertical rod 305 to support the chemical fiber threads. The top component of the roll is to place the sheath 307 on top of the main board 306, align the connecting strips 308 on the front and rear sides of the bottom with the reinforcing vertical rod 305, take the bolt 3091, put it into the spring piece 3092, pass it through the connecting strip 308 and screw it into the threaded groove 3093 to fix the sheath 307. The spring piece 3092 can buffer the vibration generated during transportation, while the sheath 307 can prevent the chemical fiber filament roll from rolling off when it is placed on the main board 306. After loading is completed, it can be transported, avoiding the axial sliding of the filaments wrapped on the surface of the paper tube due to gravity when the paper tube is placed vertically.

[0027] Reference Figure 3 , Figure 4 and Figure 5The fixing mechanism 4 includes multiple sliders 401, the tops of which are fixedly connected to the bottoms of two upright plates 2. The top left and right sides of the main plate 306 are provided with sliding grooves 402, through which the sliders 401 are slidably connected to the sliding grooves 402 for guiding and fixing the installation of the upright plates 2. The tops of the multiple sliders 401 are each provided with a slot 403, and the inner walls of the slots 403 are slidably connected with elastic fixing rods 404. The elastic fixing rods 404 are slidably connected to the slots 403 and the sliding grooves 402. The outer walls of the two elastic fixing rods 404 are each provided with a mounting groove 405 on the front and rear sides. The mounting grooves 405 are used to mount springs 406 and guide rods 407. The inner walls of the multiple mounting grooves 405... Springs 406 are fixedly connected to the walls, and the fixing blocks 408 and sliders 401 are fixed by the springs 406. Guide rods 407 are fixedly connected to the inner walls of multiple placement slots 405. The guide rods 407 are used to prevent the springs 406 from tilting. Fixing blocks 408 are fixedly connected to the opposite sides of the multiple guide rods 407. The fixing blocks 408 are slidably connected to the fixing slots 409 and slide into the corresponding slots in the sliding grooves 402, thereby fixing the position of the upright plate 2. Two fixing slots 409 are opened on the front and rear sides of the outer walls of the two elastic fixing rods 404. The outer wall of the enclosure plate 307 is provided with a reinforcing component 410. The reinforcing component 410 is used to enhance the fixing strength between the upright plate 2 and the main plate 306. The reinforcement component 410 includes multiple bolts 4101. The outer walls of the multiple bolts 4101 are threaded to the left and right sides of the outer wall of the enclosure 307. The bolts 4101 penetrate the outer wall of the enclosure 307 and the upright plate 2. Nuts 4102 are threaded to the outer walls of the multiple bolts 4101. The enclosure 307 and the upright plate 2 are connected by the connection between the bolts 4101 and the nuts 4102. Specifically, when installing the upright plate 2, align the slider 401 at the bottom of the upright plate 2 with the groove 402 at the top of the main plate 306, and push the upright plate 2 along the groove 402. The slider 401 guides the installation during the sliding process. When the slider 401 slides to the appropriate position, slide the elastic fixing rod 404 into the groove 402 and the slot 403. Then, under the tension of the spring 406, the fixing block 408 passes through the fixing groove 409 along the guide rod 407 and slides into the corresponding groove of the groove 402. This allows the elastic fixing rod 404 to fix the slider 401 and the main plate 306, initially fixing the position of the upright plate 2. Then, the bolt 4101 passes through the outer wall of the enclosure 307 and the upright plate 2. Tighten the nut 4102 at the end of the bolt 4101. The locking force of the bolt and nut 4102 enhances the connection strength between the upright plate 2 and the enclosure 307 and the main plate 306, completing the installation of the fixing mechanism 4 and ensuring that the upright plate 2 can stably limit the winding of the wire.

[0028] Reference Figure 1 , Figure 2 and Figure 4The reinforcing mechanism 6 includes multiple reinforcing ribs 601, which are used to enhance structural strength. The outer walls of the reinforcing ribs 601 are fixedly connected to the inner walls of multiple weight-reducing grooves 5. Multiple limiting grooves 602 are provided on the inner walls of the two upright plates 2. The limiting grooves 602 are used to install the reinforcing ribs 601. The mounting mechanism 7 includes two drums 701, which are used to limit the movement of the chemical fiber filament rolls. The opposite sides of the two drums 701 are slidably connected to the adjacent sides of the two upright plates 2. Slots are provided on the adjacent sides of the two upright plates 2. 702, slot 702 facilitates the installation of the drum 701, a rubber pad 8 is fixedly connected to the bottom of the base 1, the rubber pad 8 is used to reduce vibration, multiple anti-slip strips 9 are fixedly connected to the bottom of the rubber pad 8, the anti-slip strips 9 are used to increase the friction with the ground, a sponge pad 10 is fixedly connected to the adjacent side of the two upright plates 2, the sponge pad 10 is used to reduce the vibration with the chemical fiber yarn spool, two load-bearing reinforcing ribs 310 are fixedly connected to the top left and right sides of the base plate 302, the top of the load-bearing reinforcing ribs 310 is connected to the main plate 306 to increase the structural strength; Specifically, during installation, the reinforcing rib 601 is first aligned with the limiting groove 602 on the inner wall of the upright plate 2. After insertion, the outer wall of the reinforcing rib 601 is fixed to the inner wall of the weight-reducing groove 5. The reinforcing rib 601 enhances the structural strength of the upright plate 2. The two rollers 701 are aligned with the slots 702 on the adjacent sides of the two upright plates 2 respectively, and pushed in smoothly from the side to make the rollers 701 slide and connect with the upright plate 2, thus completing the limiting installation of the chemical fiber filament rolls. The rubber pad 8 at the bottom of the base 1 is pre-fixed. The anti-slip strip 9 at the bottom of the rubber pad 8 directly contacts the ground to increase friction. The sponge pads 10 on the adjacent sides of the upright plate 2 naturally conform to the filament rolls to reduce vibration. Finally, it is confirmed that the top of the load-bearing reinforcing rib 310 at the top of the base plate 302 is firmly connected to the main plate 306. The assembly of the tray is completed through the cooperation of various components, ensuring the stability and protection of the overall structure.

[0029] Working principle: A staggered support system is formed by the layered connection of reinforcing vertical rod 301, bottom support block 303, and reinforcing vertical rod 305. This system not only raises the height of the main board 306, facilitating the installation of the chemical fiber spools, but also distributes weight through the cross-bracing of the reinforcing horizontal rod 304 and vertical rods, preventing localized deformation under pressure. Furthermore, forklift holes are formed between the base plate 302, bottom support block 303, and main board 306, facilitating the transfer of the device using a forklift. The enclosure plate 307 is fixed to the reinforcing vertical rod 305 via connecting strip 308. The device forms a protective barrier, which allows the lateral displacement of the wire roll to be physically blocked and restricted when it is placed on the surface of the main board 306. The elastic buffer structure of the bolt 3091 and the spring 3092 absorbs the vibration energy generated during transportation and reduces the swaying of the wire roll. The device changes the wire roll from the traditional vertical placement to the lateral support of the main board 306. The limiting of the surrounding plate 307 replaces the simple gravity balance, and the structure eliminates the risk of axial sliding of the wire due to gravity in the vertical state, thus realizing the stable transportation of the wire on the smooth surface. Furthermore, when installing the upright plate 2, the sliding cooperation between the slider 401 and the slide groove 402 is first used to provide precise guidance for the installation of the upright plate 2, ensuring accurate positional connection. After the slider 401 is in place, the elastic fixing rod 404 is simultaneously embedded into the slide groove 402 and the slot 403. The tension of the spring 406 drives the fixing block 408 to move along the guide rod 407, so that the fixing block 408 passes through the fixing groove 409 and is locked into the corresponding groove of the slide groove 402, forming a mechanical lock and achieving the initial fixation of the upright plate 2. Then, the bolt 4101 passes through the enclosure plate 307 and the upright plate 2, and the locking force of the nut 4102 forms a rigid connection, further strengthening the overall fixing strength. This allows the device to achieve quick positioning and fixation of the upright plate 2 and the main plate 306 through the elastic component, and enhance the anti-loosening ability through the bolt connection. Finally, the upright plate 2 stably limits the wire roll, preventing displacement caused by vibration during transportation. Moreover, the device can replace the upright plate 2 of the corresponding size for different sizes of wire rolls, increasing the applicability of the device.
