Description

Technical Field

[0001] This utility model relates to the field of tire manufacturing technology, and in particular to a tire export device. Background Technology

[0002] In the tire manufacturing process, if producing semi-steel white sidewall tires, the sidewall processing is generally completed using a Ф150 / Ф200 / Ф120 three-component extrusion line. After extrusion, the tire enters the next production process, where a cover rubber is applied to the top of the white rubber to fix it. Since the extruded white rubber, bead rubber, and black sidewall rubber have already set, moving the tire sidewall to a new station for repositioning will introduce new errors. These accumulated errors can lead to misaligned cover rubber, resulting in intermittent poor tire vulcanization appearance and reduced tire performance. Furthermore, when new cover rubber is bonded to the already solidified white rubber, air bubbles can occur. These steps also increase tire manufacturing time and reduce production efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a tire export device that solves the problem that the existing technology requires separate application of cover adhesive, which can easily lead to deviations in the position of the cover adhesive.

[0004] To achieve this objective, the present invention adopts the following technical solution: The present invention provides a tire outlet device, including a main body and an extrusion plate. The upper surface of the main body is recessed downward to form a first groove, and the lower surface of the main body is recessed upward to form a second groove. A first through hole and a second through hole are provided in the main body, and the first through hole is located above the second through hole. The extrusion plate is installed on one side of the main body, and the extrusion plate is provided with a linear extrusion hole. The second groove, the first through hole, and the second through hole are connected to the extrusion hole. A connecting hole is provided above the extrusion hole, and the connecting hole is also connected to the first groove. Covering rubber flows in the first groove, sidewall rubber flows in the second groove, white rubber flows in the first through hole, and black tire sidewall rubber flows in the second through hole. The outlet of the first groove is located directly above the outlet of the first through hole.

[0005] Preferably, the extrusion plate includes an extruder and a replacement part. The replacement part is detachably installed on the extruder. The replacement part has a third through hole that communicates with the first groove. A connecting groove is formed on the lower side of the third through hole. The connecting groove and the extruder form the connecting hole. The lower edge of the replacement part is recessed upward.

[0006] Preferably, the replacement part has fixing holes on both sides, and the extruder has a screw hole on the side near the replacement part, with a screw passing through the fixing hole and screwed into the screw hole.

[0007] Preferably, the main body plate includes an upper plate component and a lower plate component, the upper plate component and the lower plate component are interlocked with each other, the upper plate component is recessed upward to form a notch, the upper plate component and the lower plate component form the extrusion hole, and the replacement part is installed on the upper plate component.

[0008] Preferably, two sets of the second through holes and the second grooves are provided, with the second through holes and the second grooves being symmetrical to each other.

[0009] Preferably, the outlet of the first through hole is located directly above the outlet of the second through hole.

[0010] Preferably, the second groove is formed diagonally below the second through hole.

[0011] Beneficial effects: By improving the structure of the tire outlet type, four different adhesives are gathered in the outlet type, allowing them to be extruded in the same process. Since the outlet of the first groove is located directly above the first through hole, the cover adhesive in the first groove can be applied on top of the white adhesive. The cover adhesive and white adhesive can be extruded in the same process, reducing one processing step and minimizing the accumulation of errors. At the same time, because the first groove is located directly above the first through hole, the relative positions of the white adhesive and the cover adhesive can remain unchanged, and they can be extruded simultaneously, ensuring that the cover adhesive always maintains an accurate application position, improving tire performance, and reducing the problem of air bubbles.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0019] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0021] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0022] In the current technology, when processing tires, it is necessary to apply white glue to the tire sidewall, and then apply cover glue on the white glue for fixation. The process of applying the cover glue comes after the process of applying the white glue. After the tire is applied with the white glue, it needs to be moved to the second process of applying the cover glue. After the second positioning, the errors may be accumulated, resulting in the deviation of the cover glue position and the problem of reduced tire performance.

[0023] To solve the above problems, such as Figures 1 to 5 As shown, this utility model provides a tire outlet device, including a main body 1 and an extrusion plate 2. The upper surface of the main body 1 is recessed downward to form a first groove 11, and the lower surface of the main body 1 is recessed upward to form a second groove 12. A first through hole 13 and a second through hole 14 are provided in the main body 1. The first through hole 13 is located above the second through hole 14. The extrusion plate 2 is installed on one side of the main body 1. The extrusion plate 2 is provided with a linear extrusion hole 21. The second groove 12, the first through hole 13 and the second through hole 14 are connected to the extrusion hole 21. A connecting hole is provided on the upper side of the extrusion hole 21. The connecting hole is also connected to the first groove 11. Covering rubber flows in the first groove 11, bead rubber flows in the second groove 12, white rubber flows in the first through hole 13, and black tire sidewall rubber flows in the second through hole 14. The outlet of the first groove 11 is located directly above the outlet of the first through hole 13.

[0024] During the operation of the tire export device, four different types of adhesives enter the main body 1 from their corresponding positions and are eventually extruded simultaneously from the extrusion holes 21 on the extrusion plate 2. At this time, the four types of adhesives are already compressed together. After being sprayed out from the extrusion holes 21, the black tire sidewall adhesive and the box adhesive are located on the lower side, while the white adhesive and the cover adhesive are located on the upper side of the black tire sidewall adhesive. The four types of adhesives can be shaped in one go after being extruded from the extrusion plate 2, which makes the tire processing more precise and reduces errors.

[0025] A first groove 11 is added to the upper side of the main body 1. Covering adhesive flows in the first groove 11, and a first through hole 13 is located directly below the first groove 11. White adhesive flows in the first through hole 13. The positions of the white adhesive and the covering adhesive are relatively fixed, and they can be shaped in one go through the outlet device, which reduces the processing steps, improves the efficiency of tire manufacturing, and allows the white adhesive and the covering adhesive to be formed in one process, reducing the probability of errors in the position of the covering adhesive, while improving the basic performance of the tire.

[0026] The extrusion plate 2 of this utility model includes an extrusion member 22 and a replacement member 23. The replacement member 23 is detachably installed on the extrusion member 22. The replacement member 23 has a third through hole 232, which communicates with the first groove 11. The covering adhesive enters the first groove 11 along the third through hole 232. A connecting groove 233 is provided on the lower side of the third through hole 232. The connecting groove 233 and the extrusion member 22 form a connecting hole. The lower edge of the replacement member 23 is recessed upward. The lower side of the replacement member 23 and the lower plate member 222 form an extrusion hole 21.

[0027] The replacement part 23 of this utility model can be replaced according to different tire size requirements, thereby changing the width of the connecting hole and thus the width of the cover rubber inside the connecting hole. This allows for flexible replacement, enabling the tire outlet device of this utility model to meet different cover rubber design widths, resulting in greater flexibility and stronger adaptability. Since there is a distance between the outlet of the first groove 11 and the outlet of the first through hole 13, the cover rubber can be guided to the upper side of the extrusion hole 21 through the connecting groove 233 on the replacement part 23. This ensures that the white rubber and cover rubber are already bonded together when extruded from the extrusion hole 21, achieving one-time molding and lower error. Furthermore, the width of the connecting hole is greater than the width of the first through hole 13, allowing the cover rubber to completely cover the white rubber, avoiding quality problems such as air bubbles, cover rubber deviation, and thickness deviation, thus improving tire stability.

[0028] The replacement part 23 of this invention has fixing holes 231 on both sides, and the extrusion part 22 has a screw hole on the side near the replacement part 23. The screw passes through the fixing hole 231 and is screwed into the screw hole. The replacement part 23 of this invention is fixed to the extrusion part 22 by screws, which facilitates the installation and removal of the replacement part 23.

[0029] The main body 1 of this utility model includes an upper plate component 221 and a lower plate component 222, which are interlocked with each other. The upper plate component 221 is recessed upward to form a notch, and the upper plate component 221 and the lower plate component 222 form an extrusion hole 21. A replacement part 23 is installed on the upper plate component 221.

[0030] Since the upper plate component 221 and the lower plate component 222 are interlocked and fixed by bolts, the size of the extrusion hole 21 can be changed by replacing the upper plate component 221 with different notch sizes. At the same time, since the upper plate component 221 and the lower plate component 222 can be separated from each other, it is convenient for cleaning and maintenance.

[0031] Two sets of second through holes 14 and second grooves 12 are provided, with the second through holes 14 being symmetrical to each other and the second grooves 12 being symmetrical to each other.

[0032] On the main body 1 of this utility model, another set of second through holes 14 and second grooves 12 are also provided. If white glue is not required during the tire processing, the black tire sidewall rubber and the bead rubber can be directly squeezed together through the other set of second through holes 14 and second grooves 12 on the main body 1 and squeezed out from another set of extrusion holes 21 on the extrusion plate 2 to realize the processing of tires of different specifications.

[0033] The outlet of the first through hole 13 is located directly above the outlet of the second through hole 14, so that the black tire sidewall rubber can fully support the white rubber. After being extruded from the extrusion hole 21, the white rubber can be stably fixed above the black tire sidewall rubber, so that the positions of the four types of rubber can be formed and fixed in sequence.

[0034] The second groove 12 is located diagonally below the second through hole 14, which allows the liner rubber and the black tire sidewall rubber to adhere to each other after being extruded from the extrusion hole 21, so that the rubber can be formed in one step.

[0035] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
