Description

Technical Field

[0001] This utility model belongs to the field of tire manufacturing technology, and specifically relates to a wire threading and traction device suitable for the calendering process. Background Technology

[0002] Tire production is a complex and precise process, mainly including key steps such as mixing, calendering, extrusion, cutting, forming, and vulcanization. These steps are crucial for ensuring the quality and performance of the final product. Among these, the calendering process is an indispensable part of manufacturing, further divided into fiber calendering and steel wire calendering. Steel wire calendering is mainly used to prepare the belt layer. This process includes multiple steps such as material handling, spindle stand, threading plates (separate threading plates and a main threading plate), EPI rollers, calendering, cooling, post-fabric storage, winding, and warehousing. In the steel wire calendering process, every step from the spindle stand to subsequent steps requires a high degree of precision. Especially after the spindle stand process is completed, the spindles need to be manually reinstalled according to a prescribed sequence, and the steel wires are threaded. This process involves pulling the steel wire to the separate threading plate for the first lead, and then pulling it to the main threading plate for the second lead. This operation is prone to problems such as steel wire crossing or even omissions, affecting tire quality and the defect rate. Utility Model Content

[0003] In view of the shortcomings of existing technologies, a wire threading and traction device suitable for the calendering process is proposed to solve the technical problems of wire crossing or even omission in existing technologies, which affect tire quality and defect rate.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A wire threading and pulling device suitable for a rolling process includes a front side plate and a rear side plate stacked together. The front side plate is provided with a plurality of front threading holes, and the rear side plate is provided with a plurality of rear threading holes. The front side plate and the rear side plate can slide relative to each other.

[0006] The front and rear wire-passing holes are initially staggered, and can partially or completely overlap during the relative sliding of the front and rear side plates to form a conductive state, thus creating a channel for the steel wire to pass through. After the front and rear side plates slide back to their original positions, the front and rear wire-passing holes return to their staggered state and apply a clamping force to the steel wire.

[0007] The technical solution is further configured such that the front side plate and the rear side plate slide relative to each other through a slide rail and a slider assembly, the slide rail is disposed on one of the side plates, and the slider is disposed on the other side plate and slidably connected to the slide rail.

[0008] The technical solution is further configured such that the end of the slide rail is fixed to one of the side plates by a mounting base, and the other side plate is provided with a clearance notch.

[0009] The technical solution is further configured such that a tension spring is provided between the front side plate and the rear side plate, and the tension spring is arranged along a sliding direction parallel to the relative sliding direction of the front side plate and the rear side plate.

[0010] The technical solution is further configured such that a locking plate is provided between the front side plate and the rear side plate, and the locking plate is located at one end of the front side plate and the corresponding end of the rear side plate.

[0011] The technical solution is further configured such that the card plate includes a connecting part and a snap-fit ​​part, the connecting part is arranged along a sliding direction parallel to the front side plate and the rear side plate, and the snap-fit ​​part is arranged perpendicular to the connecting part.

[0012] The technical solution is further configured such that the snap-fit ​​part has a snap-fit ​​surface, and the snap-fit ​​surface is provided with anti-slip texture.

[0013] The technical solution is further configured such that a hand-held protrusion is provided on the front side plate and / or the rear side plate, and the surface of the hand-held protrusion is provided with anti-slip texture.

[0014] The beneficial effects of this utility model are:

[0015] 1. When the front and rear threading holes are in a conductive state, a channel is formed, ensuring one hole and one line. This avoids the wires crossing or even missing each other during traction, eliminates the mutual wear of wires caused by cross-threading, and allows the wires to be pulled forward in a regular manner. This reduces the chance of errors in manual operation, improves the accuracy and efficiency of wire arrangement, thereby enhancing the quality and stability of the belt layer, and ultimately improving the overall performance and safety of the tire.

[0016] 2. When the front and rear wire-threading holes are staggered, a clamping force can be applied to the wire inside the holes to fix the position of the wire, making it easier to smoothly pull the wire from the branch wire-threading plate to the main wire-threading plate, thus improving the stability and reliability of the entire wire-threading process.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments in this application, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of this application. Furthermore, directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings; therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0023] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0024] According to an embodiment of this utility model, a wire threading and pulling device suitable for the rolling process is provided. Please refer to [link / reference]. Figures 1 to 3 It includes a front side plate 1 and a rear side plate 2 stacked together. The front side plate 1 is provided with a plurality of front wire holes 3, and the rear side plate 2 is provided with a plurality of rear wire holes. The front side plate 1 and the rear side plate 2 can slide relative to each other.

[0025] Furthermore, the layout of the front wire hole 3 is the same as that of the rear wire hole, and the front wire hole 3 corresponds to the wire hole of the wire distribution plate.

[0026] In use, the front threading hole 3 and the rear threading hole are initially staggered, and can partially or completely overlap during the relative sliding of the front side plate 1 and the rear side plate 2 to form a conductive state, thus creating a channel for the steel wires to pass through. This ensures that each steel wire can be independently threaded through its own channel. This design guarantees "one hole, one line," effectively preventing the steel wires from crossing or even being missed during traction, eliminating mutual wear caused by cross-threading, allowing the steel wires to be pulled forward in a regular manner, reducing the probability of errors in manual operation, improving the accuracy and efficiency of steel wire arrangement, thereby enhancing the quality and stability of the belt layer, and ultimately improving the overall performance and safety of the tire. When the front side plate 1 and the rear side plate 2 slide back to their original positions, the front threading hole 3 and the rear threading hole return to their staggered state, and a clamping force is applied to the steel wires. This clamping function facilitates the smooth traction of the steel wires from the branch threading plate to the main threading plate, ensuring that each steel wire passes through the corresponding threading hole correctly in a predetermined order. In addition, the clamping function can help fix the position of the wire and prevent it from shifting during handling or subsequent operations, thereby further improving the stability and reliability of the entire threading process.

[0027] In this embodiment, for a wire threading and traction device applicable to the rolling process, please refer to... Figures 1 to 3 The front side plate 1 and the rear side plate 2 slide relative to each other through a slide rail 4 and a slider assembly. The slide rail 4 is disposed on one of the side plates, and the slider is disposed on the other side plate and slidably connected to the slide rail 4.

[0028] Specifically, the slide rail 4 is set on the rear side plate 2, and the corresponding slider is set on the front side plate 1; the slide rail 4 is set along the height direction of the rear side plate 2, so that the front side plate 1 and the rear side plate 2 can slide relative to each other along the height direction of the rear side plate 2.

[0029] Furthermore, there are two sets of slide rail and slider assemblies, located at the two ends of the front side plate 1 and the rear side plate 2, respectively.

[0030] In this embodiment, for a wire threading and traction device applicable to the rolling process, please refer to... Figures 1 to 3 The end of the slide rail 4 is fixed to one of the side plates by a mounting base, and the other side plate is provided with a clearance notch 6.

[0031] Specifically, the slide rail 4 is located at the end of the rear side plate 2, and the mounting seat is located at the corner of the rear side plate 2. Correspondingly, the clearance notch 6 is located at the corner of the front side plate 1. This structural design can both avoid the mounting seat and provide redundant space for the relative sliding of the front side plate 1 and the rear side plate 2.

[0032] In this embodiment, for a wire threading and traction device applicable to the rolling process, please refer to... Figures 1 to 3A tension spring 5 is provided between the front side plate 1 and the rear side plate 2, and the tension spring 5 is arranged along a sliding direction parallel to the relative sliding direction of the front side plate 1 and the rear side plate 2.

[0033] Specifically, the extension direction of the tension spring 5 is parallel to the extension direction of the slide rail 4. The two ends of the tension spring 5 are connected to the front side plate 1 and the rear side plate 2 respectively through the fixing seat, so as to guide the front side plate 1 and the rear side plate 2 to slide back in the opposite direction.

[0034] In this embodiment, for a wire threading and traction device applicable to the rolling process, please refer to... Figures 1 to 3 A locking plate 7 is provided between the front side plate 1 and the rear side plate 2, and the locking plate 7 is located at one end of the front side plate 1 and the corresponding end of the rear side plate 2.

[0035] Specifically, the clamping plates 7 are located at the bottom of the front plate 1 and the top of the rear plate 2. Pulling the front plate 1 and the rear plate 2 to slide them relative to each other causes the clamping plates 7 to lock onto the edge of the wire threading plate. At the same time, with the help of the tension spring 5, the traction device is locked onto the wire threading plate. At this time, the front wire threading hole 3 and the rear wire threading hole partially or completely overlap to form a channel for the steel wire to pass through. The channel corresponds to the wire threading hole on the wire threading plate. The steel wire is guided from the wire threading plate to the channel and passes through the channel. After all the steel wire has passed through the channel, the front plate 1 and the rear plate 2 are pulled again to remove the traction device from the wire threading plate. Under the action of the tension spring 5, the front plate 1 and the rear plate 2 slide in opposite directions, causing the front wire threading hole 3 to cooperate with the rear wire threading hole to lock the steel wire. The traction device is then moved to the main wire threading plate, and the wire is threaded again in the corresponding order.

[0036] In this embodiment, for a wire threading and traction device applicable to the rolling process, please refer to... Figures 1 to 4 The card plate 7 includes a connecting part 701 and a snap-fit ​​part 702. The connecting part 701 is arranged along a sliding direction parallel to the front side plate 1 and the rear side plate 2, and the connecting part 701 is connected to the front side plate 1 and the rear side plate 2 respectively. The snap-fit ​​part 702 is arranged perpendicular to the connecting part 701.

[0037] Furthermore, the snap-fit ​​parts 702 located on the cooperating snap-fit ​​plates 7 are arranged opposite each other, snapping the edge of the wire guide plate from two directions, thereby improving the stability of the traction device.

[0038] Furthermore, the snap-fit ​​part 702 has a snap-fit ​​surface that contacts the edge of the threading plate, and the snap-fit ​​surface is provided with anti-slip texture to increase friction.

[0039] Furthermore, the end of the snap-fit ​​portion 702 away from the connecting portion 701 is bent to form a limit, thereby improving the snap-fit ​​stability between the snap-fit ​​portion 702 and the edge of the wire guide plate.

[0040] In this embodiment, for a wire threading and traction device applicable to the rolling process, please refer to... Figures 1 to 3 The front side plate 1 and / or the rear side plate 2 are provided with a hand-held protrusion 8 to facilitate picking up the traction device and to pull the front side plate 1 and the rear side plate 2 to slide relative to each other. The surface of the hand-held protrusion 8 is provided with anti-slip texture to increase friction.
