Description

Technical Field

[0001] This utility model relates to the field of polyester filament production, and in particular to a POY paper tube expansion device. Background Technology

[0002] The production of polyester filament involves a winding process, which uses a high-speed winding machine to wind the shaped polyester filament onto a POY paper tube, forming a cylindrical package. After the polyester filament is wound onto a POY paper tube, it often forms a disc-like shape, meaning the tube contains a large amount of polyester filament. Therefore, the paper tube often deforms due to the internal stress of the POY filament. Once the polyester filament on the POY paper tube is used up, the deformed tube cannot be reused, resulting in significant waste and hindering resource conservation. This also increases the production cost of polyester filament. Therefore, there is an urgent need for a device that allows for the reuse of POY paper tubes. Utility Model Content

[0003] (a) Technical problems to be solved In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a POY paper tube expanding device, which solves the problems existing in the prior art. Through the setting of this utility model, the deformed POY paper tube can be expanded and restored to its original shape, so that the POY paper tube can be reused, thereby saving resources and costs.

[0004] (II) Technical Solution

[0005] To achieve the above objectives, this utility model provides the following technical solution: a POY paper tube expanding device, including a support base, a fixed base fixed on the support base, a limiting cylinder fixed on the right side of the fixed base, a feed port opened at the right rear end of the limiting cylinder, a discharge port opened at the left front end of the limiting cylinder, a feeding ramp connected to the discharge port, a pushing mechanism fixed on the outer wall of the limiting cylinder opposite the discharge port, an expanding mechanism fixed on the left side of the fixed base, a POY paper tube feeding rack fixed on the support base, and the end of the POY paper tube feeding rack connected to the feed port.

[0006] Preferably, the pushing mechanism includes a connecting block fixed on the outer wall of the limiting cylinder, a cylinder fixed on the connecting block, the piston rod of the cylinder passing through the connecting block and the side wall of the limiting cylinder and extending into the interior of the limiting cylinder, and an arc-shaped push block fixed at the end of the piston rod of the cylinder.

[0007] Preferably, the expanding mechanism includes a hydraulic cylinder fixed to the left side of the fixed seat, the piston rod of the hydraulic cylinder extending through the fixed seat into the limiting cylinder, and a cylindrical block fixed to the end of the piston rod of the hydraulic cylinder.

[0008] Preferably, a first annular limiting block is fixed to the right end of the limiting cylinder, and a second annular limiting block is fixed to the inner wall of the left end of the discharge port, with the right end face of the second annular limiting block flush with the left end face of the discharge port.

[0009] Preferably, the POY paper tube feeding rack includes a first feeding section, which is configured to be higher at the front end and lower at the rear end. The rear end of the first feeding section is connected to a dropping section, which has a dropping port. Below the dropping section, there is a second feeding section. The second feeding section and the first feeding section are connected and fixed by several connecting rods. The second feeding section is configured to be higher at the rear end and lower at the front end, and its front end is connected to the feed port. A support section is fixedly connected to the lower part of the second feeding section, and the support section is fixed on the support base 1.

[0010] Preferably, the material discharge section is configured with a lower front end and a higher rear end, and several baffles are fixed between the material discharge section and the second material feeding section below it.

[0011] Preferably, the inner wall of the limiting cylinder has a groove for embedding an arc-shaped pusher.

[0012] (III) Beneficial Effects

[0013] 1. This utility model can automatically expand deformed POY paper tubes and restore them to their original shape, thereby enabling the POY paper tubes to be reused, saving resources and costs, and enabling batch operations with high efficiency.

[0014] 2. This utility model sets the POY paper tube feeding rack as consisting of a first feeding section, a dropping section and a second feeding section. Before expansion, the first feeding section and the second feeding section are filled with POY paper tubes horizontally. At the dropping port of the dropping section, two POY paper tubes are stacked together. This not only allows for feeding a large number of POY paper tubes at once, but also enables automatic feeding, which is very convenient.

[0015] 3. This utility model provides a groove for embedding an arc-shaped push block on the inner wall of the limiting cylinder. When the arc-shaped push block is embedded in the groove, the inner wall surface of the arc-shaped push block and the inner wall surface of the limiting cylinder are on the same arc surface. This does not affect the left and right movement of the POY paper tube, while ensuring better limiting. In addition, there is a certain distance between the two ends of the arc-shaped push block and the ends of their respective grooves. This distance ensures that the arc-shaped push block can be pushed out normally. Attached Figure Description

Detailed Implementation

[0022] The following will refer to the appendix in the embodiments of this utility model. Figure 1-5 The technical solutions in the embodiments of this utility model are clearly and completely described. 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 of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0023] This utility model provides a technical solution: a POY paper tube expanding device, including a support base 1, a fixing base 2 fixed on the support base 1, a limiting cylinder 3 fixed on the right side of the fixing base 2, a feed inlet 4 opened at the right rear end of the limiting cylinder 3, a discharge outlet 5 opened at the left front end of the limiting cylinder 3, the discharge outlet 5 is connected to a feeding ramp 6, and a pushing mechanism 7 is fixed on the outer wall of the limiting cylinder 5 opposite to the discharge outlet 5. The pushing mechanism 7 includes a connecting block 10 fixed on the outer wall of the limiting cylinder 3, and a cylinder 11 fixed on the connecting block 10. The piston rod of cylinder 11 passes through the side wall of connecting block 10 and limiting cylinder 3 and extends into the interior of limiting cylinder 3. An arc-shaped push block 12 is fixed to the end of the piston rod of cylinder 11. An expansion mechanism 8 is fixed to the left side of the fixed seat 2. The expansion mechanism 8 includes a hydraulic cylinder 13 fixed to the left side of the fixed seat 2. The piston rod of hydraulic cylinder 13 passes through the fixed seat 2 and extends into the limiting cylinder 3. A cylindrical block 14 is fixed to the end of the piston rod of hydraulic cylinder 13. A POY paper tube feeding rack 9 is fixed on the support seat 1. The end of the POY paper tube feeding rack 2 is connected to the feed port 4. The POY paper tube 24 that needs to be expanded in this utility model is as follows: Figure 5As shown, the POY paper tube 24 is cylindrical. During winding, a certain distance is left unwound at both ends of the POY paper tube 24, preventing deformation at the ends and allowing deformation only in the middle. In practice, a certain number of POY paper tubes 24 are first placed on the POY paper tube feeding rack 2, which is placed horizontally. The POY paper tubes 24 at the end of the feeding rack 2 enter the limiting cylinder 3 through the feed inlet 4. The limiting cylinder 3 is also cylindrical, with its inner diameter equal to or slightly larger than the outer diameter of the POY paper tube 24, ensuring the POY paper tube 24 is completely within the limiting cylinder 3. At this point, the hydraulic cylinder 13 of the expanding mechanism 8 is activated, extending its piston rod and driving the cylindrical block 14 to the right. The outer diameter of the cylindrical block 14... The inner diameter of the cylindrical block 14 is equal to the inner diameter of the POY paper tube 24. The center line of the cylindrical block 14 moving to the right coincides with the center line of the POY paper tube 24. Since the end of the POY paper tube 24 is not deformed, the cylindrical block 14 can extend into the POY paper tube 24, thereby expanding the POY paper tube 24 from left to right. The right end of the limiting cylinder 3 is fixed with a first annular limiting block 15, and the inner wall of the left end of the discharge port 5 is fixed with a second annular limiting block 16. The right end face of the second annular limiting block 16 is flush with the left end face of the discharge port 5. The inner diameter of the first annular limiting block 15 is smaller than the inner diameter of the POY paper tube 24. The cylindrical block 14 extends to the right end of the POY paper tube 24, thus blocking the POY paper tube 24. When the right end of the cylindrical block 14 extends to be flush with the right end of the POY paper tube 24, the hydraulic cylinder 13 reverses direction, driving the cylindrical block 14 and the POY paper tube 24 on it to move to the left. When the POY paper tube 24 moves to the left to the outlet 5, its left end is blocked by the second annular limit 16, and the cylindrical block 14 continues to move to the left until it is completely outside the POY paper tube 24. Then, the cylinder 11 of the pushing mechanism 7 is activated, its piston rod extends, driving the arc-shaped pusher 12 to move towards the POY paper tube 24. The POY paper tube 24 is pushed out of the limiting cylinder 3 from the discharge port 5. The POY paper tube 24 pushed out of the limiting cylinder 3 slides down the feeding ramp 6. A receiving frame is placed below the feeding ramp 6 to collect the expanded POY paper tube 24. After the POY paper tube 24 moves to the left to the discharge port 5, the POY paper tube 24 at the end of the POY paper tube feeding rack 9 will enter the limiting cylinder 3 through the feeding port 4 to wait. When the previous POY paper tube 24 is pushed out of the limiting cylinder 3, the POY paper tube 24 waiting in the limiting cylinder 3 is expanded, and so on.The inner wall of the limiting cylinder 3 has a groove 23 for the embedded arc-shaped pusher 12. When pushing material is not required, the arc-shaped pusher 12 is embedded in the groove 23. The inner wall surface of the arc-shaped pusher 12 and the inner wall surface of the limiting cylinder 3 are on the same arc surface, which does not affect the left and right movement of the POY paper tube 24, while ensuring better limiting. A certain distance is maintained between the two ends of the arc-shaped pusher 12 and the ends of their respective grooves, ensuring that the arc-shaped pusher 12 can be pushed out normally. This process requires the cooperation of corresponding sensors, which are existing technologies and will not be described in detail here. This invention can automatically expand and restore the deformed POY paper tube 24 to its original shape, allowing the POY paper tube 24 to be reused, saving resources and costs, and enabling batch operation with high efficiency.

[0024] The POY paper tube feeding rack 9 includes a first feeding section 17, which is configured with a higher front end and a lower rear end. A discharge section 18 is connected to the rear end of the first feeding section 17, which has a discharge port. A second feeding section 19 is located below the first feeding section 17, connected and fixed to it by several connecting rods 20. The second feeding section 19 is configured with a higher rear end and a lower front end, and its front end is connected to the feed inlet 4. A support section 21 is fixedly connected to the lower part of the second feeding section 19 and is fixed to a support base 1. Before expansion, POY paper tubes 24 are horizontally placed on the first feeding section 17 and the second feeding section 19. At the discharge port of the discharge section 18, two POY paper tubes 24 are stacked together, allowing for the feeding of a larger number of POY paper tubes 24 at once and enabling automatic feeding, which is very convenient. The material feeding section 18 is configured with a lower front end and a higher rear end, and several baffles 22 are fixed between the material feeding section 18 and the second feeding section 19 below it. This configuration plays a good role in limiting the POY paper tube 24 at this location.
