Description

Technical Field

[0001] This application relates to the field of tire forming machine reverse-wrapping capsule manufacturing technology, and more specifically, to a scar-side reverse-wrapping capsule of a semi-steel one-step forming machine. Background Technology

[0002] In traditional semi-steel one-step forming machines, the surface of the inverted bladder is smooth with a low coefficient of friction. When the pre-composite parts are bonded, the shaped sidewall comes into contact with the smooth inverted bladder. Due to the limited contact area, the two cannot achieve a tight fit, which can easily lead to relative slippage of the sidewall during the inverting process. This results in insufficient inverting of the ply layer, and the tire carcass ply cannot be tightly bonded to the bead. Ultimately, this causes the tire carcass cords to bend, leading to a series of defects such as decreased tire mechanical performance, poor dynamic balance uniformity, missing rubber or bulges on the sidewall, and a reduction in the pass rate of tire products.

[0003] In existing technologies, some improved solutions incorporate fixed scars on the capsule surface to enhance friction. However, these scars are integrally molded with the capsule body, and their width and coverage cannot be adjusted, limiting their applicability and making it difficult to meet the production needs of multiple varieties and small batches. Furthermore, during reverse wrapping, the tire sidewall is in close contact with the capsule surface, causing heat to accumulate in the contact area and preventing timely dissipation. This accelerates the aging of the capsule rubber and shortens the capsule's lifespan. Utility Model Content

[0004] To address the aforementioned problems, the present invention provides a scar-surface reverse-encapsulation capsule manufactured using a semi-steel one-step molding machine. This solves the issues of limited applicability and poor heat dissipation in existing reverse-encapsulation capsule scar structures. The capsule body includes a silicone support area and a scar area sequentially arranged along the axial direction. The silicone support area has a smooth surface. A scar module is detachably connected to the scar area. The outer surface of the scar module has multiple honeycomb-shaped protrusions. Micro-perforations are formed in the gaps between adjacent honeycomb-shaped protrusions, penetrating only the surface layer of the scar module.

[0005] Preferably, the inner surface of the scar module is provided with an elastic buckle, and the corresponding position of the capsule body is provided with a slot that cooperates with and connects to the elastic buckle.

[0006] Preferably, the scar module is further provided with positioning protrusions, and the capsule body is provided with positioning grooves that cooperate with the positioning protrusions for positioning at the corresponding positions.

[0007] Preferably, the top of the honeycomb-shaped protrusions is rounded, and the opening of the micro-perforations is rounded.

[0008] Preferably, there are multiple elastic buckles, which are evenly distributed along the scar surface module; there are multiple slots, which are spaced apart along the axial direction of the scar surface area.

[0009] Preferably, the scar module has multiple width specifications, and the elastic buckles of the scar module with different widths can engage with the corresponding slots on the scar area at the axial position.

[0010] Preferably, the end of the scar module away from the positioning protrusion is provided with at least one disassembly notch.

[0011] Preferably, the elastic buckle and the slot are interference fit.

[0012] The beneficial effects of this invention are as follows: A detachable tread module is connected to the tread area. The outer surface of the tread module has multiple honeycomb-shaped protrusions. These protrusions increase the contact area and frictional resistance between the bladder body and the tire sidewall, reducing sidewall slippage during the wrapping process. This ensures a tight fit between the ply layer and the bead, preventing cord bending and improving tire yield and production efficiency. The tread module is detachably connected to the bladder body, allowing for the replacement of tread modules of the appropriate width according to the tire specifications, enabling the same bladder body to accommodate various tire sizes. Furthermore, since the honeycomb protrusions are prone to wear due to long-term friction, worn modules can be replaced, reducing spare parts costs and extending the service life of the bladder body. Micro-perforations are provided in the gaps between adjacent honeycomb protrusions, allowing for rapid heat dissipation from the tread area during the wrapping process, preventing accelerated bladder aging caused by heat accumulation.

In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0019] The present application will now describe a scar-faced reverse-encapsulation capsule produced by a semi-steel one-step molding machine according to an embodiment of this application.

[0020] Please see Figure 1 This is a schematic diagram of the structure of the present invention. The scar-faced reverse-wrapping capsule of the semi-steel one-step molding machine includes a capsule body 1. The capsule body 1 is provided with a silicone support area 2 and a scar area 3 along the axial direction. The surface of the silicone support area 2 is smooth. A scar module 4 is detachably connected to the scar area 3. The outer surface of the scar module 4 is provided with multiple honeycomb-shaped protrusions 401. Micro-perforations are opened in the gaps between adjacent honeycomb-shaped protrusions 401, and the micro-perforations only penetrate the surface layer of the scar module 4. Specifically, the silicone support area 2 is used to support the non-cord bending area of ​​the tire sidewall. The non-cord bending area refers to the area where the cord layer has no risk of bending during reverse-wrapping molding. The cord bending area refers to the area where the tire sidewall and the capsule are prone to relative slippage and the cord layer is prone to bending during reverse-wrapping molding. The smooth surface of the silicone support area 2 can reduce friction damage, provide stable support force, and ensure the flatness of the pre-composite part. The micropores only penetrate the surface layer of the scar module 4 and do not penetrate the inner layer, thus avoiding damage to the airtightness of the capsule. At the same time, the micropores dissipate the heat accumulated in the scar area 3 during the repackaging process, solving the problems of poor heat dissipation and easy aging of traditional scar capsules and extending the service life of the capsule.

[0021] Furthermore, the honeycomb structure of the scar area 3 is preferably a regular hexagonal protrusion 401. The regular hexagonal protrusion 401 has the advantages of uniform force distribution and large contact area, which can enhance frictional resistance.

[0022] Specifically, the inner surface of the scar module 4 is provided with elastic buckles, and the corresponding position of the capsule body 1 is provided with a slot that engages with the elastic buckles. The capsule body 1 and the slot are integrally formed. The installation and removal of the scar module 4 are achieved by the engagement of the buckles and the slots, which is simple and convenient. The buckles and slots will not damage the capsule body 1 and can be reused, avoiding the scrapping of the capsule body 1 due to wear and tear on the contact surface and extending the service life of the capsule body 1.

[0023] Furthermore, the scar module 4 is also provided with positioning protrusions, and the capsule body 1 is provided with positioning grooves at corresponding positions to cooperate with the positioning protrusions. The positioning protrusions and positioning grooves cooperate to accurately limit the circumferential and axial positions of the scar module 4 on the capsule body 1, ensuring that the honeycomb protrusions 401 can be aligned with the cord bending area of ​​the tire sidewall.

[0024] Specifically, the top of the honeycomb-shaped protrusion 401 is rounded to prevent the edge of the protrusion 401 from scratching the tire sidewall rubber during the reverse wrapping process; the opening of the micro-perforation is rounded to prevent rubber debris from remaining at the opening, ensure unobstructed heat dissipation channels, and facilitate subsequent cleaning of debris inside the hole.

[0025] Furthermore, there are multiple elastic buckles, which are evenly distributed along the scar surface module 4; there are multiple slots, which are spaced apart along the axial direction of the scar surface area 3, providing connection positions for scar surface modules 4 of different widths.

[0026] Furthermore, the tread module 4 is available in various widths, and the elastic clips of different width tread modules 4 can engage with corresponding slots on the tread area 3 at axial positions. Tread modules 4 of different widths can be installed onto the capsule body 1 through slots at different locations. Since the width of the sidewall cord bending area varies for tires of different sizes, by replacing the tread module 4 with the corresponding width, the same capsule body 1 can accommodate different sizes of semi-steel tires, increasing its applicability and reducing equipment manufacturing costs. Simultaneously, the capsule body 1 can quickly switch between tread modules 4 of different widths according to production needs, improving production efficiency.

[0027] Specifically, the end of the scar module 4 away from the positioning protrusion is provided with at least one disassembly notch.

[0028] Specifically, the elastic buckle and the slot are interference fit.

[0029] In this embodiment, the width of the silicone support area 2 is 110mm, and the scar area 3 starts at 110mm from the silicone support area 2 and ends at 200mm, with a width of 90mm. The position of the scar area 3 accurately corresponds to the bending position of the sidewall reinforcing cord during molding and production. The outer surface of the scar module 4 is processed with multiple honeycomb-shaped protrusions 401. The protrusions 401 are regular hexagons with a side length of 2mm, and are spliced ​​together to form a honeycomb texture.

[0030] The working process of this utility model is as follows: Select a scuff module 4 of corresponding width according to the specifications of the tire to be produced. Align the positioning protrusions of the module with the positioning grooves of the scuff area 3 of the capsule body 1. Secure the scuff module 4 using the interference fit of the buckle and the slot, thus completing the installation. The operator transfers the pre-composite component into the molding machine and adjusts its position so that the non-cord bending area of ​​the tire sidewall fits against the silicone support area 2 of the capsule, while simultaneously aligning the cord bending area of ​​the tire sidewall with the scuff module 4. Then, activate the pre-composite mechanism to gently press the pre-composite component, ensuring complete adhesion to the capsule surface.

[0031] In this invention, a detachable tread module 4 is connected to the tread area 3. The outer surface of the tread module 4 has multiple honeycomb-shaped protrusions 401. These protrusions increase the contact area and frictional resistance between the bladder body 1 and the tire sidewall, reducing sidewall slippage during the wrapping process, ensuring a tight fit between the ply layer and the bead, preventing cord bending, and improving tire pass rate and production efficiency. The tread module 4 is detachably connected to the bladder body 1, allowing for the replacement of tread modules 4 of the appropriate width according to the specifications of the tire to be produced, enabling the same bladder body 1 to adapt to tires of various sizes. Simultaneously, since the honeycomb protrusions 401 are prone to wear due to long-term friction, worn modules can be replaced, reducing spare parts costs and extending the service life of the bladder body 1. Micro-perforations are provided in the gaps between adjacent honeycomb protrusions 401, which can quickly dissipate heat accumulated in the tread area 3 during the wrapping process, preventing accelerated bladder aging caused by heat accumulation.

[0032] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
