Description

Technical Field

[0001] This utility model belongs to the field of wire roll conveying technology, specifically concerning a wire roll conveying trolley. Background Technology

[0002] In the actual production process of the carbon fiber industry, there is a process called the unwinding process. This process requires transferring the yarn roll from the warehouse shelf to a yarn roll transport trolley, which then transfers the yarn roll to the main shaft of the unwinding machine. The yarn roll consists of a bundle of yarn wound around a hollow shaft of equal length. Currently, most companies mainly purchase a simple yarn roll transport trolley online. This trolley has basic transport and lifting functions. During operation, the height of the trolley's cantilever shaft is adjusted to align it with the hollow shaft of the yarn roll. Then, the yarn roll is manually moved from the shelf along the axial direction onto the cantilever shaft. The yarn roll transport trolley is then moved to the vicinity of the unwinding machine. By adjusting the position of the trolley and the height of the cantilever shaft, the cantilever shaft is ensured to be aligned with the main shaft of the unwinding machine. Finally, the yarn roll is manually slid from the trolley's cantilever shaft onto the main shaft of the unwinding machine. At this point, the basic work is completed.

[0003] While the aforementioned yarn roll handling trolley can perform basic handling and loading / unloading functions in actual operation, its most fatal flaw is that the transfer of the yarn roll from the shelf to the trolley's cantilever shaft and its sliding from the cantilever shaft to the unwinding machine's main shaft both rely entirely on manual pushing or pulling. This inevitably involves contact or tearing between the operator's hands and the yarn roll, easily causing the edges to loosen or collapse. This leads to knotting, tangling, and twisting of the yarn bundle during the later unwinding process, affecting the normal unwinding and operation of the yarn bundle. Furthermore, the operator's hands are highly susceptible to contamination of the yarn bundle, severely impacting its later quality.

[0004] Therefore, it is necessary to provide a wire roll conveying trolley to address the aforementioned technical issues.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Detailed Implementation

[0030] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0031] like Figure 1 As shown, in one embodiment of this utility model, the wire roll conveying trolley includes a body 8, on which two pairs of casters 801 are installed, enabling the trolley to move flexibly. At least one pair of the casters 801 is a universal wheel with a locking structure, allowing the trolley to remain stably stationary.

[0032] like Figures 1-4 As shown, a pair of body tube frames 2 are fixedly installed on the body 8, and a cantilever axle bracket 1 is slidably installed on the pair of body tube frames 2. At least two pairs of guide wheels 7 are rotatably installed on the cantilever axle bracket 1. The two pairs of guide wheels 7 can roll on the pair of body tube frames 2 respectively. The two pairs of guide wheels 7 are staggered vertically, so that the cantilever axle bracket 1 can slide and rise flexibly and stably on the body tube frames 2 with the help of the two pairs of guide wheels 7.

[0033] A cantilever shaft 3 is fixedly installed on the cantilever shaft bracket 1. The hollow shaft of the wire roll can slide on the cantilever shaft 3 to realize the loading and unloading of the wire roll on the trolley.

[0034] A lifting mechanism for driving the cantilever axle bracket 1 to slide on the body frame 2 is fixedly installed on the body 8. The lifting mechanism includes a hydraulic cylinder 4, which is fixedly installed on the body 8. A pair of sprockets 5 are rotatably mounted on the telescopic end of the hydraulic cylinder 4. A pair of chains 6 are fixedly installed on the cantilever axle bracket 1. The end of the pair of chains 6 away from the cantilever axle bracket 1 is fixed to the body frame 2 after passing through the sprockets 5.

[0035] Specifically, during the process of lifting and lowering a pair of sprockets 5 driven by the hydraulic cylinder 4, the pair of sprockets 5 will rotate, thereby pulling the cantilever shaft 3 to slide up and down along the vehicle frame 2 with the help of the guide wheel 7, so that the front end of the cantilever shaft 3 can be aligned and aligned with the rack or the main shaft of the unwinding machine.

[0036] A lead screw 10 is rotatably mounted inside the cantilever shaft 3, and a drive assembly for driving the lead screw 10 to rotate is mounted on the cantilever shaft bracket 1. The drive assembly includes a DC motor 9, which is fixedly mounted on the cantilever shaft bracket 1. A drive gear 901 is fixedly mounted on the output end of the DC motor 9. One end of the lead screw 10 extends through to the outside of the cantilever shaft 3 and is fixedly mounted with a driven gear 1001. The drive gear 901 meshes with the driven gear 1001. The DC motor 9 can indirectly drive the lead screw 10 to rotate through the drive gear 901 and the driven gear 1001.

[0037] The drive assembly may also include a cylinder. Compressed air is provided on the trolley, and the cylinder is used instead of the DC motor 9 as a power source. It can also indirectly drive the lead screw 10 to rotate through the drive gear 901 and the driven gear 1001.

[0038] like Figure 5 As shown, a nut 12 is threaded onto the lead screw 10, and a connecting piece 13 is fixedly installed on the nut 12. A slot 302 is provided at the bottom of the cantilever shaft 3, and one end of the connecting piece 13 passes through the slot 302 and is fixedly installed with a push-pull rod 14. The lead screw 10 can drive the nut 12, causing the connecting piece 13 on the nut 12 to slide inside the slot 302, thereby driving the push-pull rod 14 to slide and push the hollow shaft of the wire coil, realizing loading and unloading.

[0039] Among them, multiple sets of universal balls 301 are rotatably installed on the cantilever shaft 3. The multiple sets of universal balls 301 are located on the upper surface of the cantilever shaft 3. By arranging universal balls 301 on the upper surface of the cantilever shaft 3, the resistance of the wire roll sliding on the cantilever shaft 3 is greatly reduced.

[0040] In addition, both the lead screw 10 and the nut 12 are hidden inside the cantilever shaft 3, so they will not contaminate the wire roll.

[0041] like Figure 5 As shown, a clamping assembly is fixedly installed at one end of the push-pull rod 14. The clamping assembly includes a clamp 15, and one end of the hollow shaft of the wire coil can be inserted into the clamp 15. A screw hole is provided on the clamp 15, and a locking bolt 16 passes through the screw hole. By rotating the locking bolt 16, the hollow shaft of the wire coil can be tightened and fixed.

[0042] One end of the locking bolt 16 is located inside the clamp 15 and is fixedly mounted with a clamping block 1602. The clamping block 1602 increases the contact area with the hollow shaft of the wire coil, improving the stability of its fixation. The other end of the locking bolt 16 is fixedly mounted with a knob 1601, which allows for easy manual rotation of the locking bolt 16, enhancing operability.

[0043] A DC battery 11 is fixedly installed on the vehicle body 8. The DC battery 11 is used as a power source. The DC battery 11 is directly installed on the vehicle body 8, so the car can be moved around very easily.

[0044] In use, fix the clamp 15 to the end of the hollow shaft of the wire roll; drag the trolley close to the hollow shaft of the wire roll; start the DC motor 9, which drives the lead screw 10 to rotate through the drive gear 901 and the driven gear 1001, moving the nut 12 forward to the front of the cantilever shaft 3; by adjusting the position of the trolley, and simultaneously driving the sprocket 5 to rise and fall through the hydraulic cylinder 4, the cantilever shaft bracket 1 slides up and down along the frame 2 of the vehicle body with the help of the guide wheel 7 until the cantilever shaft 3 is aligned with the hollow shaft of the wire roll; connect the nut 12 and the clamp 15 together through the connecting piece 13 and the push-pull rod 14; lock the trolley casters; start the DC motor 9 in reverse to pull the hollow shaft of the wire roll (including the wire roll) from the shelf. The upper part is fitted onto the cantilever shaft 3 and pulled to the desired position; the trolley casters are opened, and the trolley is dragged to the working area; by adjusting the position of the trolley, the hydraulic cylinder 4 is raised and lowered, the sprocket 5 rotates, and the chain 6 pulls the cantilever shaft bracket 1 to slide up and down along the body tube frame 2 with the help of the guide wheel 7 until the front end of the cantilever shaft 3 is aligned with the main shaft of the unwinding machine; the trolley casters are locked; the DC motor 9 is started to drive the lead screw 10 to rotate, causing the nut 12 to move forward. Under the action of the connecting piece 13 and the push-pull rod 14, the hollow shaft of the wire roll (including the wire roll) is pushed along the cantilever shaft 3 onto the main shaft of the unwinding machine; at this point, the wire roll transfer is completed. The trolley casters are opened, and the trolley is dragged to the working area.

[0045] The trolley for conveying the filament rolls of this invention eliminates the need for manual pushing and pulling of the filament rolls, thus completely preventing operators from touching the filament rolls or bundles.

[0046] While retaining the basic functions of the original transport trolley, a clamping component is added. When the wire coil is on the cantilever shaft 3 of the upper and lower transport trolleys, a lead screw 10 and nut 12 transmission method is used to realize linear reciprocating motion. The structure is simple and easy to maintain. The power source is provided by DC battery 11 and DC motor 9. The power source is installed on the vehicle body 8 and can be moved with the trolley at any time, realizing semi-automatic loading and unloading of wire coils, reducing labor intensity and improving product quality.

[0047] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
