Description

Technical Field

[0001] This application belongs to the field of steel cord production technology, and relates to a horizontal I-beam wheel locking mechanism and steel cord production equipment. Background Technology

[0002] Currently, steel cord production equipment using an external take-up and internal take-up method employs a vertical take-up mechanism. The steel cord is wound onto 315 or B80 type I-beam reels. While the vertical take-up structure is simple, it suffers from frequent wire routing failures and a low steel cord yield. Horizontal internal take-up, on the other hand, can not only wind up larger I-beam reels and achieve better wire routing, but also allows for the installation of a height-adjustable roller at the take-up point to ensure steel cord quality. However, the internal space of the internal take-up cradle is limited, and the flywheel rotates at high speed, making it impossible to install pneumatic or electric locking devices inside.

[0003] Horizontal internal winding and stranding equipment cannot be widely adopted, and there is an urgent need for a horizontal I-beam wheel locking mechanism with a simple and reliable structure. Summary of the Invention

[0004] Objective: In view of at least one of the above technical problems, this application provides a horizontal I-beam wheel locking mechanism and steel cord production equipment.

[0005] Technical solution: To solve the above-mentioned technical problems, the technical solution adopted in this application is as follows:

[0006] In one aspect, a horizontal I-beam wheel locking mechanism is provided, comprising a handwheel, a housing, a sliding sleeve, a center shaft, and a center;

[0011] In some embodiments, the horizontal I-beam wheel locking mechanism further includes an elastic compression member, which is compressed at the end of the handwheel away from the housing. Under the pressure of the elastic compression member, the handwheel is pushed to fit tightly against the housing so that the external gear meshes with the internal gear, thereby locking the handwheel to prevent the sliding sleeve from sliding.

[0012] Furthermore, in some embodiments, the horizontal I-beam wheel locking mechanism further includes a spring cover, which is connected to the end of the first shaft diameter of the sliding sleeve; the handwheel has an elastic element mounting groove around the inner hole on the side near the spring cover for mounting an elastic compression element, one end of the elastic compression element is limited and installed in the groove, and the other end is compressed and fixed by the spring cover.

[0013] Furthermore, the elastic compression component uses a compression spring.

[0014] In some embodiments, the external gear has a gear module m of 0.8 and a number of teeth of 138.

[0015] In some embodiments, the helical groove is a half-turn helical groove, and the helix angle α is less than 10°.

[0016] In some embodiments, a tapered roller bearing and a deep groove ball bearing are provided between the center shaft and the sliding sleeve, and the deep groove ball bearing is axially limited by a round nut;

[0017] The tip is keyed to the tip shaft, and the maximum outer diameter of the tip is axially limited by the tip cap, which is connected and installed at the end of the second shaft diameter of the sleeve.

[0018] Furthermore, in some embodiments, the maximum outer diameter portion of the tip is connected to the tip cap via a labyrinth seal structure.

[0019] In some embodiments, the tip is conical with a cone angle of 60°.

[0020] Secondly, a steel cord production equipment is provided, including the aforementioned horizontal I-beam wheel locking mechanism.

[0021] Beneficial effects: The horizontal I-beam locking mechanism and steel cord production equipment provided in this application have a simple structure, are stable and reliable, and can effectively lock the horizontal I-beam directly by operating the handwheel. Attached Figure Description

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0031] Example 1: As Figures 1 to 6 As shown, a horizontal I-beam wheel locking mechanism includes a handwheel 5, a housing 6, a sliding sleeve 9, a center shaft 14, and a center 12;

[0032] The center 12 mates with the inner hole of the I-beam wheel; the center 12 is mounted on the shaft end of the center shaft 14, and the center shaft 14 is axially limited and rotated within the sliding sleeve 9;

[0033] The sliding sleeve 9 includes a first shaft diameter portion 9-1 and a second shaft diameter portion 9-2 connected to each other. The outer diameter of the first shaft diameter portion is smaller than the outer diameter of the second shaft diameter portion, and a first limiting step is formed at the connection between the first shaft diameter portion and the second shaft diameter portion.

[0034] The handwheel 5 is sleeved on the outer circumference of the first shaft diameter and is connected to the sliding sleeve 9 by a flat key 3 with clearance fit; the outer casing 6 is slidably sleeved on the outer circumference of the second shaft diameter of the sliding sleeve 9 with clearance fit.

[0035] An external gear 6-1 is provided on the outer periphery of the first end of the outer casing 6; an internal gear 5-1 that meshes with the external gear is provided on the side of the handwheel 5 near the outer casing 6; a spiral groove 6-2 that communicates with the outer wall of the sliding sleeve 9 is provided on the cylindrical wall of the outer casing 6; a roller bearing 16 is connected and installed on the outer wall of the sliding sleeve 9 corresponding to the spiral groove, so that the sliding sleeve 9 can rotate forward or backward in the outer casing 6 under the guidance of the roller bearing 16 and the spiral groove 6-2, thereby driving the tip 12 to move axially to tighten the I-beam wheel.

[0036] In this application, the outer diameter of the sliding sleeve is slightly smaller than the inner diameter of the outer shell, with intermittent fit, allowing the sliding sleeve to slide flexibly.

[0037] In this embodiment, as Figure 3 As shown, an external gear 6-1 is machined at one end of the outer casing 6. The gear module m is 0.8, and the number of teeth is 138. A semi-circular helical groove 6-2 is machined on the cylindrical wall of the outer casing 6, with a helix angle α less than 10°. The small helix angle ensures a certain degree of self-locking. Figure 2 As shown, countersunk holes are machined on the edge of the outer casing 6, and six second screws 8 are used to fix it to the bracket 7. The bracket 7 can be part of the twisting machine or can be connected and fixed to the twisting machine. The countersunk holes on the edge of the outer casing facilitate the fixing of the outer casing.

[0038] In some embodiments, the horizontal I-beam wheel locking mechanism further includes an elastic compression member 4, which is compressed and disposed at the end of the handwheel 5 away from the housing 6. Under the pressure of the elastic compression member 4, the handwheel 5 is pushed to be close to the housing 6 so that the external gear 6-1 meshes with the internal gear 5-1, thereby locking the handwheel 5 to prevent the sliding sleeve 9 from sliding.

[0039] Furthermore, the horizontal I-beam wheel locking mechanism also includes a spring cover 2, which is connected to the end of the first shaft diameter of the sliding sleeve 9; the handwheel 5 has a groove around the inner hole on the side near the spring cover 2 for installing the elastic compression member 4, one end of the elastic compression member 4 is limited and installed in the groove, and the other end is compressed and fixed by the spring cover 2.

[0040] In this embodiment, the elastic compression member 4 is a compression spring.

[0041] In this embodiment, a tapered roller bearing 15 and a deep groove ball bearing 17 are provided between the center shaft 14 and the sliding sleeve 9, and the deep groove ball bearing 17 is axially limited by a brake washer 19 and a round nut 20. The center 12 is connected to the center shaft 14 by a flat key 13, and the maximum outer diameter of the center 12 is axially limited by a center cap 11, which is connected and installed at the end of the second shaft diameter 9-2 of the sliding sleeve 9. The center shaft and center are installed inside the sliding sleeve by the tapered roller bearing 15 and the deep groove ball bearing 17, allowing for flexible rotation. In this way, while locking the horizontal I-beam wheel by the center 12 to prevent axial movement of the I-beam wheel, the center shaft and center can also rotate with the I-beam wheel.

[0042] In this embodiment, the maximum outer diameter of the tip 12 is connected to the tip cap 11 through a labyrinth sealing structure to prevent foreign objects from entering the interior.

[0043] In this embodiment, the tip 12 is conical with a cone angle of 60°, and this structure mates with the inner hole of the I-beam wheel. During operation, as the sliding sleeve moves forward, the tip 12 presses against the inner hole of the I-beam wheel.

[0044] In this embodiment, there are multiple deep groove ball bearings 17, and spacers 18 are provided between the multiple deep groove ball bearings.

[0045] In this embodiment, as Figure 3 , Figure 4 As shown, a thread is machined on the outer circumference of the second shaft diameter of the sliding sleeve 9 to install a set of roller bearings 16. The outer diameter of the roller bearings 16 is slightly smaller than the width of the helical groove 6-2 on the outer shell wall. Guided by the helical groove, the sliding sleeve 9 rotates forward or backward within the outer shell 6. A flat keyway is machined on the outer circumference of the first shaft diameter of the sliding sleeve 9 for installing a flat key-3 to connect the handwheel 5. A spring cap 2 is installed on the end face using three first screws 1.

[0046] like Figure 5 , Figure 6As shown, the handwheel 5 has several protrusions on its outer ring. Near the spring cap 2, on the outer side of the inner hole, there is a ring of elastic element mounting grooves 5-2 for mounting the elastic compression element 4. A keyway 5-3 is machined in the inner hole for mounting the flat key 3. The handwheel 5 and the sliding sleeve 9 are connected via the flat key 3 with a clearance fit. Near the outer casing 6, on the side of the handwheel 5, there is a ring of internal gears 5-1, whose tooth profile matches the external gears 6-1 of the outer casing 6.

[0047] During operation, grasp handwheel 5 and pull it outwards. The internal gear 5-1 separates from the external gear 6-1, and rotates counterclockwise, causing the sliding sleeve 9 to rotate together and move backwards relative to the outer casing 6. Figure 7 As shown. After the I-beam wheel is placed in the designated position, turn the handwheel 5 clockwise to move the center point 12 forward, tightening the I-beam wheel, as shown. Figure 2 As shown, under the action of the elastic compression member 4, the internal gear 5-1 of the handwheel 5 meshes with the external gear 6-1 of the outer casing 6, locking the I-beam wheel.

[0048] The horizontal I-beam wheel locking mechanism provided in this application has a simple structure, is easy to operate, is stable and reliable, and can effectively lock the horizontal I-beam wheel.

[0049] Example 2: A steel cord production equipment, including the horizontal I-beam wheel locking mechanism described in Example 1.

[0050] Furthermore, the outer shell 6 of the horizontal I-beam wheel locking mechanism is connected and installed on the twisting machine via a bracket 7.
