Technical Field

[0001] This invention belongs to the field of wire processing technology, and specifically relates to a paper wire reel unloading device. Background Technology

[0002] Currently, many steel-plastic composite pipe production lines use metal wire reels supplied directly by the manufacturers. During production, after the wire is used up, the manufacturers collect the empty reels, wind them up, and then ship them out. However, metal wire reels are irreparable once damaged. Using paper-spooled reels can replace metal reels, extending the production cycle. This eliminates the need for manufacturers to collect the reels and resend them, and since the paper reels are provided by the manufacturers, usage costs are reduced, which helps to lower costs and increase efficiency, and solves the problem of inconsistent supply during production. Summary of the Invention

[0003] The present invention provides a paper thread reel feeding device, which effectively improves the production cycle, increases the utilization rate of the paper thread reel, and is easy to operate, thus solving the problem of non-continuous supply in production as mentioned in the background art.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A paper thread reel feeding device includes a base connected to a stepped shaft, the stepped shaft connected to a feeding unit, and the feeding unit including a thread reel support shaft rotatably connected to the stepped shaft. One end of the thread reel support shaft is connected to a fixed baffle, and the other end is movably connected to a movable baffle. A paper thread reel is sleeved on the thread reel support shaft, located between the fixed baffle and the movable baffle. The movable baffle has a plurality of cylinders at its end away from the fixed baffle, with each cylinder spaced circumferentially around the movable baffle. The thread reel support shaft is movably connected to a chuck, and the chuck has a plurality of arc-shaped grooves near its end against the movable baffle, each arc-shaped groove corresponding to one of the cylinders. Correspondingly, the spool support shaft is fixedly connected to the stepped shaft by a nut; one end of the spool support shaft is provided with a snap-fit ​​shaft, and the end of the snap-fit ​​shaft away from the spool support shaft is provided with a plurality of guide posts, each guide post being spaced apart circumferentially along the snap-fit ​​shaft; the thickness of the guide post and the snap-fit ​​shaft is equal to the thickness of the spool support shaft; the outer diameter of the snap-fit ​​shaft is adapted to the inner diameter of the chuck; the thickness of the chuck is equal to the distance between the spool support shaft and the guide post; the chuck is provided with a plurality of guide grooves, each guide groove corresponding to one of the guide posts; the end of the chuck away from the arc-shaped inclined groove is provided with a plurality of limiting posts, each limiting post being spaced apart circumferentially along the chuck; the limiting post corresponding to one of the guide posts.

[0006] Furthermore, the two ends of the coil support shaft are respectively fixedly connected to the outer rings of corresponding bearings, and the inner rings of each bearing are fixedly connected to the stepped shaft.

[0007] Furthermore, a damping assembly is provided on the outer side of the bearing, and the damping assembly is located between the bearing and the nut.

[0008] Furthermore, the damping assembly includes a bearing end cap and a damping spring. One end of the bearing end cap abuts against the bearing, the other end of the bearing end cap abuts against the damping spring, and the other end of the damping spring abuts against the nut.

[0009] Furthermore, there are two wire feeding units, which are located at both ends of the stepped shaft.

[0010] Furthermore, the stepped shaft is provided with a connecting component, which is located between the two wire feeding units. When the connecting component is in the working position, the stepped shaft is fixedly connected to the base.

[0011] The technological advancements achieved by this invention compared to existing technologies, due to the adoption of the aforementioned structure, are as follows:

[0012] (1) The base of this invention is connected to a stepped shaft, which is connected to a wire feeding unit. The wire feeding unit includes a wire reel support shaft, which is rotatably connected to the stepped shaft. One end of the wire reel support shaft is connected to a fixed baffle, and the other end is movably connected to a movable baffle. A paper reel is sleeved on the wire reel support shaft, and the paper reel is located between the fixed baffle and the movable baffle. The movable baffle has several cylinders at its end away from the fixed baffle, and the cylinders are spaced apart circumferentially along the movable baffle. The wire reel support shaft is movably connected to a chuck, and the chuck has several arc-shaped grooves at its end near the movable baffle. The arc-shaped grooves correspond one-to-one with the cylinders. The wire reel support shaft is connected by screws. The female is fixedly connected to the stepped shaft; this device uses the interaction between the cylinder of the movable baffle and the arc-shaped inclined groove of the chuck. During the rotation of the paper wire axis disc, the resistance causes the movable baffle to rotate as well, causing the cylinder on the movable baffle to slide on the inclined surface of the arc-shaped inclined groove. As the paper wire axis disc rotates, the movable baffle gradually clamps the paper wire axis disc, preventing the copper wire from coming off during the rotation of the paper wire axis disc, thus improving the stability of the copper wire. The paper wire axis disc is provided by the supplier, reducing the cost of use and helping to reduce costs and increase efficiency. It also avoids the manufacturer taking back the discs and resupplying them, solving the problem of non-continuous supply in production pointed out in the background technology.

Detailed Implementation

[0030] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of the invention.

[0031] Example 1: A paper axis reel unloading device

[0032] This embodiment discloses a paper thread reel feeding device, such as... Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 , Figure 9 , Figure 11 , Figure 12As shown, the device includes a base 1, which can be fixedly connected to a stepped shaft 2 by welding. The base 1 can also be fixedly connected to the stepped shaft 2 via a connecting assembly 12. The stepped shaft 2 is connected to a wire feeding unit, which includes a wire reel support shaft 3. The wire reel support shaft 3 is rotatably connected to the stepped shaft 2. One end of the wire reel support shaft 3 is fixedly connected to a fixed baffle 4 by welding, and the other end is movably connected to a movable baffle 5. A paper reel 6 is fitted onto the wire reel support shaft 3. The paper reel 6 is provided by the supplier and is wound with steel wire, reducing usage costs and improving efficiency. This avoids the manufacturer reselling the wire reels, thus solving the production issues mentioned in the background section. To address the issue of inconsistent supply, the paper reel 6 is located between the fixed baffle 4 and the movable baffle 5. Multiple cylinders 501 are fixedly connected to the end of the movable baffle 5 furthest from the fixed baffle 4 via welding. Alternatively, the movable baffle 5 can be integrally formed with the cylinders 501. The cylinders 501 are spaced apart circumferentially along the movable baffle 5. The reel support shaft 3 is movably connected to the chuck 7. Multiple arc-shaped grooves 701 are formed at the end of the chuck 7 closest to the movable baffle 5, each corresponding to a cylinder 501. The reel support shaft 3 is fixedly connected to the stepped shaft 2 via nuts 8. One end of the reel support shaft 3 is fixedly connected to the snap-fit ​​shaft 9 via welding. The snap-fit ​​shaft 9 can also be integrally formed with the reel support shaft 3. The clamping shaft 9 is formed with multiple guide posts 901 at the end away from the thread spool support shaft 3. These guide posts 901 are spaced apart circumferentially along the clamping shaft 9. The guide posts 901 and the clamping shaft 9 are integrally formed, and their thickness is equal to the thickness of the thread spool support shaft 3. This arrangement facilitates the connection of the paper thread spool 6 to the thread spool support shaft 3. The inner diameter of the paper thread spool 6 matches the outer diameter of the thread spool support shaft 3. The outer diameter of the clamping shaft 9 matches the inner diameter of the chuck 7, and the thickness of the chuck 7 is equal to the distance between the thread spool support shaft 3 and the guide posts 901. The chuck 7 has multiple guide grooves 702 formed by a machine tool, with each guide groove 702 corresponding to a guide post 901. This arrangement... First, it facilitates the chuck 7 to be fitted onto the clamping shaft 9; second, after the chuck 7 is fitted onto the clamping shaft 9, rotating the chuck 7 causes it to clamp between the guide post 901 and the spool support shaft 3, facilitating the fixation of the chuck 7; this makes the installation process simple and convenient, saving manpower and resources, and also facilitating disassembly; the end of the chuck 7 away from the arc-shaped inclined groove 701 is fixedly connected to multiple limiting posts 703 by welding. The limiting posts 703 can also be integrally formed with the chuck 7. The multiple limiting posts 703 are spaced apart along the circumference of the chuck 7, and the limiting posts 703 correspond one-to-one with the guide posts 901. The limiting posts 703 and the guide posts 901 cooperate with each other to prevent the chuck 7 from rotating along the clamping shaft 9, thus improving the stability of the chuck 7;In use, firstly, the thread spool support shaft 3 is fixedly connected to the fixed baffle 4. Then, the thread spool support shaft 3 is rotatably connected to the stepped shaft 2. Next, the stepped shaft 2 is connected to the base 1. Then, the paper thread spool 6 is fitted onto the thread spool support shaft 3. Next, the movable baffle 5 is fitted onto the thread spool support shaft 3, with the cylindrical end 501 moving away from the fixed baffle 4. Then, the guide groove 702 of the chuck 7 slides into the guide post 901 of the clamping shaft 9, and the cylindrical end 501 of the movable baffle 5 extends into the arc-shaped inclined groove 701 of the chuck 7. The chuck 7 is rotated, causing the guide groove 702 of the chuck 7 to deviate from the guide post 901 and the movable baffle 5 to be fixed. Finally, the stepped shaft 2 is threadedly connected to the nut 8, and the nut 8 locks the thread spool support shaft 3. Therefore, the advantage of this embodiment is that by adopting the above settings, the service life can be increased, usage costs can be saved, and cost reduction and efficiency improvement can be achieved.

[0033] Example 2

[0034] like Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 10 , Figure 11 As shown, the two ends of the spool support shaft 3 are respectively fixedly connected to the outer rings of the corresponding bearings 10, and the inner ring of each bearing 10 is fixedly connected to the stepped shaft 2, so that the spool support shaft 3 is rotatably connected to the stepped shaft 2 through the bearings 10; a damping assembly 11 is provided on the outside of the bearings 10, and the damping assembly 11 is located between the bearings 10 and the nut 8. The damping assembly 11 includes a bearing end cover 1101 and a damping spring 1102. The bearing end cover 1101 is sleeved on the stepped shaft 2, one end of the bearing end cover 1101 abuts against the bearing 10, and the other end of the bearing end cover 1101 abuts against one end of the damping spring 1102. The other end of the damping spring 1102 abuts against the nut 8. The damping spring 1102 can be adjusted by the nut 8 on the stepped shaft 2; the damping spring 1102 can slow down the rotation speed of the bearings 10, so that the steel wire has a certain tension due to the slow rotation of the spool support shaft 3.

[0035] Example 3

[0036] like Figure 1 , Figure 6 , Figure 11The described structure includes two wire-feeding units, located at both ends of the stepped shaft 2. The stepped shaft 2 is equipped with a connecting component 12, situated between the two wire-feeding units. When the connecting component 12 is in its working position, the stepped shaft 2 is fixedly connected to the base 1. This arrangement facilitates disassembly between the stepped shaft 2 and the base 1. The connecting component 12 includes two U-bolts, four nuts, and a connecting plate. The connecting plate has four through holes, each corresponding to one of the two free ends of the two U-bolts. In use, the two U-bolts are inserted into the stepped shaft 2, with their free ends passing through the corresponding through holes. The connecting plate is located at the lower end of the base 1, and the four nuts are threaded onto their corresponding free ends. Tightening the nuts securely connects the stepped shaft 2 to the base 1. The connecting component 12 can also be other existing structures. Therefore, the advantage of this embodiment is that the above-described arrangement facilitates disassembly between the stepped shaft 2 and the base 1.

[0037] The working principle of this invention is as follows:

[0038] In use, first, fix the thread spool support shaft 3 to the fixed baffle 4. Then, rotate the thread spool support shaft 3 to the stepped shaft via the bearing 10. Next, fix the stepped shaft 2 to the base 1 via the connecting assembly 12. Then, fit the paper thread spool 6 onto the thread spool support shaft 3. Next, fit the movable baffle 5 onto the thread spool support shaft 3 and move the cylindrical end 501 away from the fixed baffle 4. Then, slide the guide groove 702 of the chuck 7 along the guide post 901 of the clamping shaft 9 and extend the cylindrical end 801 of the movable baffle 5 into the arc-shaped inclined groove 701 of the chuck 7. Rotate the chuck 7 so that the guide groove 702 of the chuck 7 deviates from the guide post 901 and fix the movable baffle 5. Finally, fit the bearing end cover 1101 and the damping spring 1102 onto the stepped shaft 2 and thread the nut 8 onto the stepped shaft 2. As the nut 8 rotates, the bearing end cover 1101 presses against the bearing 10 under the pressure of the damping spring 1102.

[0039] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention.
