[0002] The winding shaft of a spinning machine is an important component of the spinning machine. Its main function is to install the yarn bobbin and wind the spun yarn onto the bobbin for subsequent processing and transportation.

[0003] Chinese patent CN214782338U discloses a winding mechanism for a rotor spinning machine, including a base plate, side plates, a winding drum, and a winding drive. Two side plates are provided and are located at both ends of the base plate. The base plate and the two side plates form a space for placing the winding drum. Both ends of the winding drum are detachably and rotatably mounted on the side plates. The winding drive is located on the side plates and connected to the winding drum to drive the winding drum to rotate.

[0004] The winding mechanism of this rotor spinning machine is a winding drum used to install yarn bobbins. The diameter of the winding drum is fixed, which makes it impossible to install yarn bobbins with different inner diameters, thus limiting its use. Utility Model Content

[0005] The purpose of this invention is to provide a spinning machine winding shaft structure that can be fitted with yarn bobbins of different inner diameters, enabling winding operations for yarn bobbins of different inner diameters, thus improving versatility.

[0006] To achieve the above objectives, this utility model provides a spinning machine winding shaft structure, including a main shaft body. A baffle is fixedly connected to the outer end of the main shaft body. An inner rotating cylinder is coaxially fixedly connected to the outer end of the baffle. A retaining sleeve is detachably fitted to the outer end of the inner rotating cylinder. A retaining ring is fixedly connected to the inner end of the retaining sleeve. An outer rotating cylinder is detachably fitted to the outer side of the inner rotating cylinder. The inner rotating cylinder and the outer rotating cylinder are connected by an insertion fit. A plurality of axially extending limiting slots are provided on the outer side of the outer rotating cylinder.

[0007] Preferably, the outer side of the inner rotating cylinder is provided with a plurality of axially extending limiting inner slots, and the inner wall of the outer rotating cylinder is provided with a plurality of inserts that are fitted into the limiting inner slots one by one.

[0008] Preferably, the inner wall of the inner rotating cylinder is provided with a first reinforcing rib that corresponds one-to-one with the inner limiting slot, and the part of the insert outside the inner limiting slot is provided as a second reinforcing rib with a trapezoidal cross-section.

[0009] Preferably, the limiting outer slot is configured to correspond one-to-one with the second reinforcing rib, and the limiting outer slot extends partially into the second reinforcing rib.

[0010] Preferably, the inner rotating cylinder surface is provided with a plurality of first weight reduction holes located between two adjacent limiting inner slots.

[0011] Preferably, the outer rotating cylinder surface is provided with a plurality of second weight reduction holes between two adjacent limiting outer slots.

[0012] Preferably, the outer end surface of the inner rotating cylinder is provided with a plurality of screw holes along the axial direction, the retaining sleeve is provided with a through hole, and a screw capable of being screwed into the screw hole is provided in the through hole.

[0013] Preferably, the outer side of the retaining sleeve is provided with a flat surface, and the through hole is provided through the flat surface.

[0014] According to the above technical solution, this utility model provides a winding shaft structure for a spinning machine, including a main shaft body. A baffle is fixedly connected to the outer end of the main shaft body. An inner rotating cylinder is coaxially fixedly connected to the outer end of the baffle. A retaining sleeve is detachably fitted to the outer end of the inner rotating cylinder. A retaining ring is fixedly connected to the inner end of the retaining sleeve. An outer rotating cylinder is detachably fitted to the outer side of the inner rotating cylinder. The inner rotating cylinder and the outer rotating cylinder are connected by an insertion fit. A plurality of axially extending limiting slots are provided on the outer side of the outer rotating cylinder.

[0015] The winding shaft structure of this spinning machine has the following advantages: It features an inner drum with a fixed outer diameter. In conventional use, a yarn bobbin with a smaller inner diameter is fitted onto the inner drum, and then its lateral movement is limited by baffles and retaining rings. When the inner diameter of the yarn bobbin is larger than the outer diameter of the inner drum, an outer drum can be fitted over the inner drum before fitting the yarn bobbin. The outer and inner drums are mutually restrained by an insertion-type fit for circumferential deflection. Therefore, this winding shaft structure allows for the fitting of yarn bobbins with different inner diameters, enabling winding operations on yarn bobbins of varying inner diameters, thus increasing its versatility.

[0016] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation

[0026] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0027] In this utility model, unless otherwise stated, directional terms such as "up, down, left, right, front, back, inside, outside" in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as a limitation on the term.

[0028] See Figure 1-6 The spinning machine winding shaft structure shown includes a main shaft body 1. A baffle 2 is fixedly connected to the outer end of the main shaft body 1. An inner rotating cylinder 8 is coaxially fixedly connected to the outer end of the baffle 2. A retaining sleeve 7 is detachably fitted to the outer end of the inner rotating cylinder 8. A retaining ring 6 is fixedly connected to the inner end of the retaining sleeve 7. An outer rotating cylinder 3 is detachably fitted to the outer side of the inner rotating cylinder 8. The inner rotating cylinder 8 and the outer rotating cylinder 3 are connected by an insertion fit. A plurality of axially extending limiting slots 5 are provided on the outer side of the outer rotating cylinder 3.

[0029] Through the implementation of the above technical solution, the winding shaft structure of this spinning machine has an inner drum 8 with a fixed outer diameter. In normal use, a yarn bobbin with a smaller inner diameter is fitted onto the inner drum 8, and then limited laterally by the baffle 2 and retaining ring 6. When the inner diameter of the yarn bobbin is larger than the outer diameter of the inner drum 8, an outer drum 3 can be fitted over the inner drum before fitting the yarn bobbin. The outer drum 3 and the inner drum 8 are limited in circumferential deflection through an insertion fit. Therefore, this winding shaft structure of the spinning machine can accommodate yarn bobbins of different inner diameters, enabling winding operations for yarn bobbins of different inner diameters, thus improving its versatility.

[0030] In this invention, the main shaft 1 is connected to a motor or other transmission components. The structure of the connection position is adapted according to the type of the connected components, such as a flange connection or a threaded connection.

[0031] In this embodiment, to further provide a mating insertion structure between the inner rotating cylinder 8 and the outer rotating cylinder 3, the outer surface of the inner rotating cylinder 8 is provided with a plurality of axially extending limiting inner slots 9, and the inner wall of the outer rotating cylinder 3 is provided with a plurality of inserts 14 that mate with each of the limiting inner slots 9. The multiple limiting inner slots 9 serve two purposes: firstly, they can mate with the inserts 14; secondly, they can mate with the ribs on the inner wall of the yarn bobbin to prevent circumferential slippage of the yarn bobbin. The limiting inner slots 9 can be T-shaped, flat, or their inner ends can be spherical.

[0032] In this embodiment, the inner wall of the inner rotating cylinder 8 is provided with first reinforcing ribs 16 corresponding one-to-one with the limiting inner slots 9, and the portion of the insert 14 located outside the limiting inner slots 9 is provided as a second reinforcing rib 15 with a trapezoidal cross-section. Since the outer wall of the inner rotating cylinder 8 is provided with multiple limiting inner slots 9, the location where the limiting inner slots 9 are located is relatively weak. Therefore, the first reinforcing ribs 16 are provided to increase the strength of the location where the limiting inner slots 9 are located. The second reinforcing rib 15 has a similar function to the first reinforcing rib 16, improving the strength of the outer rotating cylinder 3. Furthermore, the width of the second reinforcing rib 15 gradually increases from the inside to the outside along the radial direction, also increasing the supporting strength of the outer rotating cylinder 3.

[0033] In this embodiment, the limiting outer slot 5 is configured to correspond one-to-one with the second reinforcing rib 15, and the limiting outer slot 5 partially extends into the second reinforcing rib 15. The function of the limiting outer slot 5 is to cooperate with the ribs provided on the inner wall of the yarn bobbin and insert to prevent the yarn bobbin from slipping circumferentially.

[0034] In this embodiment, a plurality of first weight-reducing holes 13 are provided on the surface of the inner rotating cylinder 8 between two adjacent limiting inner slots 9. This arrangement reduces the weight of the inner rotating cylinder 8.

[0035] In this embodiment, a plurality of second weight-reducing holes 4 are provided on the surface of the outer rotating cylinder 3 between two adjacent limiting outer slots 5. This arrangement reduces the weight of the outer rotating cylinder 3.

[0036] In this embodiment, the outer end surface of the inner rotating cylinder 8 is provided with a plurality of screw holes 10 along the axial direction, and the retaining sleeve 7 is provided with a through hole, in which a screw 12 capable of being screwed into the screw hole 10 is provided. With this arrangement, the distance between the baffle 2 and the retaining ring 6 can be adjusted by screwing the screw 12 into different screw holes 10, thereby enabling the limiting installation of yarn bobbins of different lengths.

[0037] In this embodiment, a flat surface 11 is provided on the outer side of the retaining sleeve 7, and the through hole is provided through the flat surface 11. After the screw 12 is installed in place, it is pressed against the flat surface 11, making the screw 12 more stable.

[0038] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0039] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0040] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
