Description

Technical Field

[0001] This utility model relates to the field of pusher plate technology, and in particular to a novel non-destructive pusher plate device for FDY winding heads. Background Technology

[0002] The development of the chemical fiber industry is closely related to technological progress. With the continuous emergence and application of new technologies, the production efficiency and product quality of chemical fibers have been significantly improved. Among them, after the FDY yarn is prepared, it needs to be wound and unloaded by a winding machine. When the winding machine is winding, the paper tube is installed on the winding head, and the FDY yarn is wound by rotation. After the winding is completed, the paper tube and yarn are pushed away from the winding head by the push plate.

[0003] Existing pushers are driven by cylinders or other structures during operation. However, the winding machine needs to push 12 yarn cakes each time the yarn is dropped, resulting in frequent pusher movements. This makes the pushers prone to loosening, causing tube breakage during pushing and contributing to equipment instability, which in turn affects the quality of FDY yarn. Therefore, a new technical solution is urgently needed to solve at least one of the above technical problems. Summary of the Invention

[0004] In view of the above shortcomings, the purpose of this utility model is to provide a new type of non-destructive push plate device for FDY winding heads, which increases the connection strength between the push plate body and the cylinder and reduces the possibility of the push plate body loosening during use.

[0005] To achieve the above-mentioned technical objectives and meet the above-mentioned technical requirements, the technical solution adopted by this utility model is as follows:

[0006] A novel non-destructive pusher device for FDY winding heads includes:

[0007] The push plate body is used to push the paper tube;

[0008] A guide rod, one end of which slides through the push plate body to form a guide hole on the push plate body, and the other end of the guide rod is connected to the winding machine;

[0009] An installation cylinder is mounted on the push plate body and used to connect with the cylinder. An extrusion shell is slidably mounted on the installation cylinder. A first inclined surface is provided inside the extrusion shell so that the inner diameter of the extrusion shell at the location of the first inclined surface is smaller than the outer diameter of the installation cylinder.

[0010] As a preferred technical solution, the push plate body is provided with an insertion hole, and a limit plate is connected to the insertion hole by a set screw thread, and the mounting cylinder is mounted on the limit plate.

[0011] As a preferred technical solution, a pad is installed on the pusher plate body. The friction coefficient of the pad is less than that of the pusher plate body, and the pusher plate body contacts the paper tube through the pad.

[0012] As a preferred technical solution, the guide rod surface is provided with multiple grooves, and the push plate body is equipped with multiple sliding blocks that slide in cooperation with the grooves.

[0013] As a preferred technical solution, both the limiting plate and the push plate body are provided with positioning holes, and a magnetic column is inserted into the positioning hole.

[0014] As a preferred technical solution, a limiting groove is provided on the mounting cylinder, and a limiting block is installed inside the extrusion shell and slidably inserted into the limiting groove.

[0015] As a preferred technical solution, a counterweight is installed on the side of the push plate body away from the pad, so that the center of gravity of the push plate body is away from the pad.

[0016] As a preferred technical solution, the sliding block is provided with a rolling groove, and a rolling ball is rolled and installed in the rolling groove, with the rolling ball rolling and engaging with the groove.

[0017] Compared with traditional technical solutions, the beneficial effects of this utility model are:

[0018] In use, the push plate body is connected to the cylinder via an mounting cylinder. When it slides, it is connected to the guide rod via a guide hole, which limits the inner wall of the guide hole and restricts the tendency of the push plate body to rotate around the cylinder's telescopic end axis. An extrusion shell is installed on the mounting cylinder, and the inner diameter of the extrusion shell is reduced by the first inclined surface. When the cylinder drives the push plate body to reset, it causes the extrusion shell to come into contact with the winding machine, which in turn extrudes the mounting cylinder. This increases the connection strength between the push plate body and the cylinder and reduces the possibility of the push plate body loosening during use. Attached Figure Description

[0025] The present invention will now be further described with reference to the accompanying drawings.

[0026] In the accompanying drawings of this utility model, the same or similar reference numerals correspond to the same or similar components. In the description of this utility model, it should be understood that if terms such as "top," "bottom," "left," "right," "front," "rear," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0027] Please refer to Figures 1-3 This utility model provides a novel non-destructive pusher device for an FDY winding head, comprising a pusher body 1 for pushing a paper tube. Since the paper tube is sleeved on the rotating shaft of the winding head of the winding machine, the pusher body 1 has an arc-shaped groove. Through the arc-shaped groove, the pusher body 1 contacts the rotating shaft of the winding head of the winding machine, so that the pusher body 1 can better fit the rotating shaft, and the pusher body 1 can contact the paper tube carrying the FDY yarn after winding. By sliding the pusher body 1, it pushes the paper tube and the FDY yarn, so that the paper tube is separated from the winding head for unloading.

[0028] The guide rod 2 has one end that slides through the push plate body 1 to form a guide hole 3 on the push plate body 1. The other end of the guide rod 2 is connected to the winding machine. The guide rod 2 is slidably inserted into the push plate body 1 through the guide hole 3, so that when the push plate body 1 slides, the inner wall of the guide hole 3 is blocked and restricted by the guide rod 2, so that the push plate body 1 can only slide in a straight line when it slides, which increases the stability of the push plate body 1 when it slides.

[0029] The mounting cylinder 4 is mounted on the push plate body 1 and used to connect with the cylinder. An extrusion shell 5 is slidably mounted on the mounting cylinder 4. A first inclined surface is formed inside the extrusion shell 5, such that the inner diameter of the extrusion shell 5 at the location of the first inclined surface is smaller than the outer diameter of the mounting cylinder 4, and the inner diameter of the extrusion shell 5 at the location without the first inclined surface is larger than the outer diameter of the mounting cylinder 4. Figure 5As shown, the mounting cylinder 4 is tightly connected to the cylinder extension end by a tight insertion. The mounting cylinder 4 also has an inclined surface parallel to the first inclined surface. In use, when the cylinder pulls the push plate body 1 to reset, the extrusion shell 5 will abut against the winding machine housing or the cylinder housing, causing the extrusion shell 5 to slide towards the mounting cylinder 4 and abut against it. During the abutment, the guide between the inclined block on the mounting cylinder 4 and the first inclined surface causes the smaller inner diameter part of the extrusion shell 5 to abut against and squeeze the mounting cylinder 4. At this time, the inner wall of the mounting cylinder 4 abuts against the cylinder extension end, restoring the connection strength between the two weakened by high-frequency movement, thereby enabling the device to connect more stably with the cylinder. In use, when the push plate body 1 resets each time, the extrusion shell 5 can squeeze the mounting cylinder 4, increasing the connection strength between it and the cylinder and reducing the possibility of shaking during use.

[0030] When the cylinder extension end pushes the push plate body 1, the guide rod 2 restricts the tendency of the push plate body 1 to rotate around the axis of the cylinder extension end by blocking the inner wall of the guide hole 3, which further increases the stability of the push plate body 1 in use.

[0031] Compared with the prior art, in use, the push plate body 1 is connected to the cylinder through the mounting cylinder 4. When it slides, it is connected to the guide rod 2 through the guide hole 3, so that the guide rod 2 limits the inner wall of the guide hole 3, restricting the tendency of the push plate body 1 to rotate around the cylinder telescopic end axis. Furthermore, an extrusion shell 5 is installed on the mounting cylinder 4, and the inner diameter of the extrusion shell 5 is reduced by the first inclined surface. When the cylinder drives the push plate body 1 to reset, it causes the extrusion shell 5 to come into contact with the winding machine, so that the extrusion shell 5 extrudes the mounting cylinder 4, and the mounting cylinder 4 comes into contact with the cylinder telescopic end. This increases the connection strength between the push plate body 1 and the cylinder and reduces the possibility of the push plate body 1 loosening during use.

[0032] like Figure 2 and Figure 4 As shown, the push plate body 1 has an insertion hole 6, and a limit plate 7 is connected to the insertion hole 6 by a set screw. The mounting cylinder 4 is installed on the limit plate 7. The insertion hole 6 has a thread, and the limit plate 7 also has a threaded hole. In use, the guide hole 3 on the push plate body 1 is aligned with the guide rod 2, the push plate body 1 is inserted into the guide rod 2, and then the threaded hole on the limit plate 7 is aligned with the insertion hole 6 on the push plate body 1. The push plate body 1 and the limit plate 7 are connected by a set screw, so that the push plate body 1 can be disassembled. When the push plate body 1 is worn out after prolonged use, or when it is necessary to add lubricating oil to the guide rod 2, the push plate body 1 can be disassembled, which facilitates the disassembly and replacement of the push plate body 1 and the addition of lubricating oil to the guide rod 2, thus increasing the practicality of the device.

[0033] like Figure 1As shown, a pad 8 is installed on the pusher plate body 1. The friction coefficient of the pad 8 is lower than that of the pusher plate body 1. The pusher plate body 1 contacts the paper tube through the pad 8. The pad 8 is made of nylon, which has a low friction coefficient. The pad 8 is installed on the side of the pusher plate body 1 that contacts the paper tube, so that the pusher plate body 1 contacts the paper tube through the pad 8. During use, this reduces the friction between the pusher plate body 1 and the paper tube, thereby reducing the wear of the pusher plate during the pushing process and thus reducing the tube breakage rate. The pusher plate body 1 has threaded holes, and the pad 8 has holes for inserting bolts, allowing the pad 8 to be connected to the pusher plate body 1 through countersunk screws. This allows the pad 8 to be replaced during use, and the countersunk screw connection prevents the formation of protrusions on the pad 8, reducing the possibility of damage to the paper tube during pushing.

[0034] like Figure 1 and Figure 2 As shown, the guide rod 2 has multiple grooves 9 on its surface, and the push plate body 1 is equipped with multiple sliding blocks 10 that slide in conjunction with the grooves 9. The push plate body 1 is slidably installed in the grooves 9 through the sliding blocks 10. The sliding blocks 10 and the grooves 9 increase the contact points between the push plate body 1 and the guide rod 2. When the push plate body 1 slides, by increasing the contact points between it and the guide rod 2, the guide rod 2 can better support the push plate body 1, thereby increasing the stability of the push plate body 1 when sliding and reducing the possibility of the push plate body 1 shaking when pushing.

[0035] like Figure 2 and Figure 3 As shown, both the limiting plate 7 and the push plate body 1 have positioning holes 11, and magnetic posts 12 are inserted into the positioning holes 11. The surfaces of the limiting plate 7 and the push plate body 1 are made of cast iron, and the magnetic posts 12 are magnets. When it is necessary to connect the push plate body 1, the magnetic posts 12 are inserted into the push plate body 1, and then the push plate body 1 is inserted into the guide rod 2 and slid towards the limiting plate 7. When the magnetic posts 12 are connected to the positioning holes 11 on the limiting plate 7, the magnetic posts 12 attract the surface of the limiting plate 7 to fit with the surface of the push plate body 1, so that the threaded holes on the limiting plate 7 are aligned with the insertion holes 6 on the push plate body 1. This reduces the operation time of aligning the threaded holes with the insertion holes 6 when installing the push plate body 1 and increases the convenience of installing the push plate body 1.

[0036] like Figure 4 and Figure 5As shown, a limiting groove 13 is provided on the mounting cylinder 4, and a limiting block 14 is installed inside the extrusion shell 5 and slidably inserted into the limiting groove 13. When the extrusion shell 5 is sliding, the limiting groove 13 limits the side wall of the limiting block 14, so that the extrusion shell 5 can only slide in a straight line, which increases the stability of the extrusion shell 5 when sliding. In addition, the inner wall of the limiting groove 13 limits the sliding range of the limiting block 14, so that the extrusion shell 5 will not separate from the mounting cylinder 4 when it slides to the maximum distance, which increases the stability of the extrusion shell 5 during use.

[0037] like Figure 3 As shown, a counterweight 15 is installed on the side of the push plate body 1 away from the pad 8, so that the center of gravity of the push plate body 1 is away from the pad 8. When the device is in use, the pad 8 is located on the top of the push plate body 1, and the counterweight 15 is located at the end of the push plate body 1 facing the ground. The counterweight 15 makes the center of gravity of the push plate body 1 lower, and the guide hole 3 is also located close to the bottom of the push plate body 1, so that the push plate body 1 can slide more stably on the guide rod 2, increasing the stability of the push plate body 1 when sliding.

[0038] like Figure 2 As shown, a rolling groove 16 is provided on the sliding block 10, and a rolling ball 17 is rolled in the rolling groove 16. The rolling ball 17 rolls with the groove 9. The rolling groove 16 has an opening, so that the rolling ball 17 can be exposed from the rolling groove 16. The sliding block 10 contacts the inner wall of the groove 9 through the rolling ball 17. The sliding block 10 itself does not contact the groove 9. When the push plate body 1 slides on the guide rod 2, the sliding block 10 rolls with the groove 9 through the rolling ball 17. The contact between the rolling ball 17 and the groove 9 increases the contact points between the push plate body 1 and the guide rod 2. At the same time, the rolling reduces the friction between the push plate body 1 and the guide rod 2, reducing the possibility of fluctuations on the push plate body 1 caused by friction.
