Description

Technical Field

[0001] The present invention relates to the technical field of cord fabric winding equipment, in particular to an ejector pin structure for cord fabric winding. Background Art

[0002] After the cord fabric has completed the dipping process, it needs to be wound up using a winder to facilitate transportation. The cord fabric winder winds up the cord fabric by driving the reel to rotate, and the drive shaft and reel of the cord fabric winder are connected by a thimble.

[0003] The thimbles used in the cord fabric winder include square-headed thimbles and conical thimbles, and the reels include corresponding square-hole reels and round-hole reels. The combination of square-headed thimbles and square-hole reels has good stability and is not prone to sliding. However, when replacing different reels, the size of the square hole of the reel also changes, and the square-headed thimbles of the corresponding size need to be replaced. During the production process, the square-headed thimbles need to be frequently disassembled and replaced, resulting in an increased probability of failure. The conical thimble can adapt to the inner hole of round-hole reels of different diameters. When replacing the reel, the thimble does not need to be replaced, reducing the replacement frequency. Therefore, more and more manufacturers are replacing square-headed thimbles with conical thimbles, but the square-headed thimbles and square-hole reels have not been completely replaced.

[0004] This results in the existence of both square-hole reels and round-hole reels in the tire cord production line and the winding reel supply chain. When the conical thimble is in contact with the square-hole reel, there are only four contact points between the thimble and the square hole of the reel, and the contact area is small, resulting in less friction between the thimble and the square hole of the reel. When the winder drives the reel to rotate through the conical thimble, slippage and wear are likely to occur. Summary of the Invention

[0005] In response to the technical problems existing in the prior art, the first aspect of the present invention provides an ejector pin structure for winding tire cord fabric, comprising an ejector pin body, one end of which is provided with an ejector pin component, the ejector pin component being configured in a truncated cone shape so as to be capable of engaging with a square-hole reel or a round-hole reel;

[0006] The narrowed end of the top connecting part is defined as the first end, and the enlarged end is defined as the second end.

[0007] A connecting seat for connecting to a drive shaft of a winder is coaxially fixed to the second end of the top connecting member;

[0008] The top connecting member is detachably connected to a limiting member, the limiting member comprising at least one limiting rib, and slots corresponding to the number of the limiting ribs are provided along the first end surface and the second end surface of the top connecting member;

[0009] When the limiting rib is inserted into the slot, the limiting rib extends to the outside of the conical surface of the top-connecting component and can limit the square hole corner of the square hole reel.

[0010] Preferably, the limiting component is in the shape of a straight line or a cross.

[0011] Preferably, when the limiting component is in the shape of a straight line, it comprises two limiting ribs spliced ​​together to form a straight line cross-section, and the corresponding slot is in the shape of a straight line radially penetrating the top-connecting component.

[0012] Preferably, when the limiting component is cross-shaped, it includes four limiting ribs spliced ​​into a cross-shaped cross section, and the corresponding slot is a cross-shaped slot that penetrates radially along the top connection component.

[0013] Preferably, the distance from the limiting rib to the outer side of the conical surface of the top-connecting component gradually increases from the first end to the second end of the top-connecting component.

[0014] Preferably, the first end of the supporting component is provided with at least one fixing component, and the limiting component can be fixed to the supporting component through the fixing component.

[0015] Preferably, the fixing component includes a bolt, and the end surface of the first end of the top connection component is provided with a threaded hole corresponding to the bolt, and the bolt is threadedly connected in the threaded hole so that the head of the bolt can press the limiting component onto the top connection component.

[0016] Compared with the prior art, the thimble structure for winding up the cord fabric proposed in the present invention is achieved by providing a slot on the truncated cone-shaped thimble component, and detachably connecting a limiting rib in the slot, and the limiting rib can extend to the outside of the conical surface of the thimble component. When the square hole reel is thimbled, the limiting rib can extend to the area outside the conical surface of the thimble component at the corner of the square hole, and can limit the square hole corner of the square hole reel. When the winder drives to rewind, the thimble body and the square hole reel will not slip. The limiting rib is removed, and the truncated cone-shaped thimble component can be used to thimble with the circular hole of the circular hole reel. The truncated cone-shaped thimble component can adapt to the inner holes of reels of different sizes and does not need to be frequently replaced. The device can simultaneously perform good thimble connection on both the circular hole reel and the square hole reel, and has high adaptability. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to better understand the technical content of the present invention, specific embodiments are given and described below with reference to the accompanying drawings.

[0025] Combine Figure 1 As shown, the present invention provides an ejector pin structure for cord fabric winding, comprising an ejector pin body 10 and a limiting member 20. An ejector pin body 10 has an ejector pin 11 at one end. The ejector pin 11 is configured in a truncated cone shape, enabling it to engage both square-hole and round-hole reels. Furthermore, the truncated cone shape of the ejector pin 11 can adapt to the inner holes of reels of different sizes, eliminating the need for frequent replacement.

[0026] Combine Figure 1 、 2 As shown, the narrowed end of the top connecting part 11 is defined as the first end, and the enlarged end is defined as the second end. A connecting seat 12 is coaxially fixed to the second end of the top connecting part 11. The connecting seat 12 is provided with a connecting groove corresponding to the winder drive shaft. The ejector body 10 is connected to the winder drive shaft through the connecting seat 12.

[0027] When the conical thimble contacts the square-hole reel, there are only four contact points between the thimble and the square hole of the reel, and the contact area is small, resulting in less friction between the thimble and the square hole of the reel. When the winder drives the reel to rotate through the conical thimble, slippage and wear are likely to occur.

[0028] Combine Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the top connection member 11 is detachably connected to the limiting member 20, which includes at least one limiting rib 21. Slots 101 corresponding to the number of the limiting ribs 21 are provided along the first end surface and the second end surface of the top connection member 11. When the limiting ribs 21 are inserted into the slots 101, the limiting ribs 21 extend to the outside of the conical surface of the top connection member 11 (such as Figure 1 shown).

[0029] In this way, when the square hole reel is connected, the limiting rib 21 is first inserted into the slot 101, and then the connecting component 11 is inserted into the square hole of the square hole reel. When the connecting component 11 is inserted, the limiting rib 21 is directed toward the corner of the square hole. After the connecting component 11 is connected to the horizontal surface of the square hole, the limiting rib 21 extends to the area outside the conical surface of the connecting component 11 at the corner of the square hole (such as Figure 3 As shown), the square hole corner of the square hole reel can be limited, and when the reel is driven to rewind, the ejector body 10 and the square hole reel will not slip.

[0030] When the circular hole reel is connected, the limiting rib 21 is removed and the truncated cone-shaped connecting component 11 is used to connect with the circular hole of the circular hole reel. The truncated cone-shaped connecting component 11 can adapt to the inner holes of reels of different sizes and does not need to be replaced frequently.

[0031] Combine Figure 3 and Figure 4 As shown, the limiting component 20 is in a straight or cross shape.

[0032] Furthermore, when the limiting component 20 is in the shape of an I-shape, it includes two limiting ribs 21 spliced ​​into an I-shape in cross section, and the corresponding slot 101 is set to be in the shape of an I-shape radially passing through the top component 11. At this time, the two limiting ribs 21 can limit the two corners of the square hole to avoid slipping.

[0033] When the limiting component 20 is cross-shaped, it includes four limiting ribs 21 spliced ​​into a cross-shaped cross-section, and the corresponding slot 101 is a cross-shaped slot radially extending through the top component 11. At this time, the four limiting ribs 21 can limit the four corners of the square hole to improve stability.

[0034] Combine Figure 1 and Figure 2 As shown, the distance from the limiting rib 21 to the outside of the conical surface of the top connection part 11 gradually increases from the first end to the second end of the top connection part 11, so that the limiting rib 21 can limit square holes of various sizes, improving adaptability.

[0035] Combine Figure 2 and Figure 5As shown, at least one fixing component 30 is provided at the first end of the top connecting component 11 , and the limiting component 20 can be fixed on the top connecting component 11 through the fixing component 30 .

[0036] Furthermore, the fixing component 30 includes a bolt, and a threaded hole 102 corresponding to the bolt is opened on the end face of the first end of the top connecting component 11. After the limiting rib 21 is inserted into the slot 101, the bolt is threadedly connected in the threaded hole 102, so that the head of the bolt can press the limiting rib 21 onto the top connecting component 11, fix the limiting rib 21, and prevent the limiting rib 21 from falling.

[0037] In combination with the above embodiment, a slot 101 is provided on the truncated cone-shaped top-connecting member 11, and the limiting rib 21 is detachably connected in the slot 101, and the limiting rib 21 can extend to the outside of the conical surface of the top-connecting member 11. When the square hole reel is top-connected, the limiting rib 21 can extend to the area outside the conical surface of the top-connecting member 11 at the corner of the square hole (such as Figure 3 As shown in the figure), it can limit the corner of the square hole of the square hole reel. When the reel is driven to reel, the ejector body 10 and the square hole reel will not slip. The limiting rib 21 is removed, and the truncated cone-shaped top connection component 11 can be used to connect with the round hole of the round hole reel. The truncated cone-shaped top connection component 11 can adapt to the inner holes of reels of different sizes and does not need to be frequently replaced. The device can perform good top connection on both the round hole reel and the square hole reel at the same time, and has high adaptability.

Persons skilled in the art will readily appreciate that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
