Description

Technical Field

[0001] This utility model relates to the field of heat insulation cover technology, specifically a flexible high-temperature resistant heat insulation cover for tire vulcanizing equipment. Background Technology

[0002] The tire vulcanizing unit is the "ultimate molding equipment" in rubber tire manufacturing. By precisely controlling the three core parameters of temperature, pressure and time, it causes the green tire blank (composed of rubber, cord, steel wire and other composites) to undergo a cross-linking reaction, forming a finished tire with a fixed shape, mechanical properties and wear resistance.

[0003] Application number CN201921365456.2 discloses a high-temperature resistant insulation shell, including a fixed flange, an inner stainless steel cover, an insulation layer, an outer stainless steel cover, ceramic sheets, a fixed edge, a plug-in edge, an extension edge, a bending edge, a connecting edge, and an insertion edge. The left side of the fixed flange is fixedly connected to the right side of the inner stainless steel cover. The inner wall of the insulation layer is fitted with the outer wall of the inner stainless steel cover, and the inner wall of the outer stainless steel cover is fitted with the outer wall of the insulation layer. The four sides of the outer wall of the outer stainless steel cover are fixedly connected to the inner walls of four ceramic sheets. This utility model achieves the purpose of isolating the product inside from external heat conduction when it is in a high-temperature environment, thereby ensuring a low-temperature state inside the insulation shell. It is also applicable to other high-temperature environments where internal heat protection is required, thus improving the product's immunity to high-temperature conditions.

[0004] The insulation shell is fixedly connected to the inner stainless steel cover via a fixed flange. The whole structure is a rigid, integrated structure with no adjustable parts. It can only rely on the single mounting position of the fixed flange. In practical applications, when installing it with equipment components, the components need to be manually adjusted for alignment. It cannot be quickly adjusted in circumferential angle or radial position, resulting in insufficient versatility. Utility Model Content

[0005] The purpose of this invention is to provide a flexible, high-temperature resistant insulation cover for a tire vulcanizing device, which solves the problem of lacking a positioning and adjustment structure.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a flexible high-temperature resistant insulation cover for a tire vulcanizing device, comprising a fixed base and an insulation cover. The insulation cover is installed on the top inner wall of the fixed base. The fixed base includes an annular base, and an annular groove is formed on the inner wall of the top four sides of the annular base. Annular sliders are slidably connected to the inner walls on both sides of the annular groove. The top of the two sets of annular sliders is provided with an arc-shaped plate. The top of the adjacent surfaces of the two arc-shaped plates is provided with a toothed block group. The arc-shaped plate is in contact with the inner wall of the annular base. An annular sleeve block is fitted between the two arc-shaped plates. A toothed groove ring is formed on the outer ring of the annular sleeve block. The toothed blocks of the two arc-shaped plates respectively mesh with the inner walls on both sides of the toothed groove ring of the annular sleeve block.

[0007] The purpose of this setup is that during the installation process, the annular base of the fixed base is first fixed in the corresponding position of the tire vulcanizing device to ensure that the annular groove is placed horizontally. Then, the annular sliders at the bottom of the arc plates on both sides of the heat insulation cover are aligned with the annular groove and slid in, so that the inner wall of the arc plate is tightly fitted with the inner wall of the annular base. Next, place the annular sleeve between the two curved plates, so that the toothed block group at the top of the curved plate precisely meshes with the toothed groove ring on both sides of the outer ring of the annular sleeve. By rotating the annular sleeve, the transmission action between the toothed block and the toothed groove is used to drive the two curved plates to rotate synchronously along the annular groove through the annular slider, thereby realizing the circumferential angle adjustment of the heat insulation cover. After adjusting the insulation cover to be aligned and matched with the feed inlet, observation window and other components of the vulcanizing device, stop rotating the ring sleeve. The meshing and self-locking of the toothed block group and the toothed groove ring can fix the position of the arc plate, so that the insulation cover is stably installed and fits the vulcanizing device to form a closed insulation space, thus completing the installation and angle adjustment process. The toothed ring of the annular sleeve meshes with the toothed block group of the arc plate, driving the arc plate to rotate along the annular groove via the annular slider. This allows for precise adjustment of the circumferential angle of the heat insulation cover, facilitating its alignment with components such as the feed inlet and observation window of the vulcanizing device and avoiding structural interference.

[0008] Furthermore, a stainless steel cover is fixedly inserted into the inner ring of the annular sleeve, and an annular insert cover is provided at the bottom end of the stainless steel cover.

[0009] The purpose of this design is to fix a stainless steel cover inside the annular sleeve during the use of the structure. The high temperature resistance of stainless steel enhances the heat resistance of the core area of ​​the insulation cover, preventing deformation of the cover due to high temperature sulfidation. At the same time, the annular insert at the bottom of the stainless steel cover can form a nested fit with the components below, further strengthening the connection stability between the stainless steel cover and the overall structure.

[0010] Furthermore, a thickened base plate is fixedly connected between the two arc-shaped plates, and the top of the tooth block assembly applies pressure to the tooth groove of the annular sleeve block.

[0011] The purpose of this design is to fix a thickened chassis between the two curved plates during the use of the structure. Its heavy structure provides bottom support for the curved plates, enhancing the overall resistance to deformation. At the same time, the thickened chassis applies upward support force to the curved plates, ensuring that the tooth block assembly continuously and tightly meshes with the tooth groove ring of the annular sleeve block, preventing the meshing part from loosening after rotational adjustment.

[0012] Furthermore, the top of the thickened chassis is provided with a rubber ring layer, and the outer ring of the rubber ring layer is connected to the inner side of the two arc-shaped plates.

[0013] The purpose of this design is that, during the use of this structure, the outer ring of the thickened rubber ring at the top of the chassis connects with the inner side of the two curved plates, which can fill the gap between the curved plates and the chassis, improve the heat insulation and sealing performance, and the elastic properties of the rubber can also buffer the slight vibration when the curved plates rotate, avoid direct friction and wear of metal parts, and at the same time maintain flexibility at high temperatures to prevent the gap from widening due to thermal expansion and contraction.

[0014] Furthermore, the annular insert is vertically inserted into the inner ring of the rubber ring layer, and the bottom end of the annular insert is located on the inner wall of the bottom surface of the thickened chassis.

[0015] The purpose of this design is that, during installation, the annular insert at the bottom of the stainless steel cover is vertically inserted into the inner ring of the rubber ring layer. The rubber ring layer tightly wraps around the outer wall of the annular insert layer through elastic deformation, forming a sealed connection. The bottom of the annular insert layer abuts against the inner wall of the thickened bottom surface of the chassis. The weight of the stainless steel cover is distributed by the chassis, preventing it from sagging due to its own weight, while also enhancing the bottom sealing of the insulation space.

[0016] Furthermore, a positioning ring is provided at the top of the stainless steel cover, and the positioning ring is located in the middle of the stainless steel cover.

[0017] The purpose of this design is that, during the use of this structure, when the insulation cover is installed as a whole, the positioning ring can be fixedly connected to the clinker pipe of the tire vulcanizing device. The conveying pipe passes through the inner ring of the positioning ring, and the positioning ring restricts the radial displacement of the clinker pipe through its own structure, so as to prevent the clinker pipe from shifting its position due to vibration or high temperature during the material conveying process.

[0018] This utility model has the following beneficial effects: (1) By setting up an annular sleeve block and an arc plate, the annular sleeve block's toothed groove ring meshes with the arc plate's toothed block group, driving the arc plate to rotate along the annular groove via an annular slider. This allows for precise adjustment of the circumferential angle of the heat insulation cover, making it easy to align with components such as the feed inlet and observation window of the vulcanizing device, thus avoiding structural interference.

[0019] (2) In this utility model, the annular insert and the rubber ring layer are set. The annular insert at the bottom of the stainless steel cover is vertically inserted into the inner ring of the rubber ring layer. The rubber ring layer tightly wraps the outer wall of the annular insert through elastic deformation to form a sealed connection. The bottom of the annular insert abuts against the inner wall of the thickened bottom surface of the chassis. The weight of the stainless steel cover is distributed by the chassis to prevent it from sagging due to its own weight, while strengthening the bottom sealing of the heat preservation space.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4As shown, this utility model is a flexible high-temperature resistant heat insulation cover for a tire vulcanizing device, including a fixed base 1 and a heat insulation cover 2. The heat insulation cover 2 is installed on the top inner wall of the fixed base 1. The fixed base 1 includes an annular base 101. Annular grooves 102 are formed on the inner walls around the top of the annular base 101. Annular sliders 203 are slidably connected to the inner walls on both sides of the annular grooves 102. Arc plates 201 are provided at the top of the two sets of annular sliders 203. Tooth block groups 202 are provided on the top of the adjacent surfaces of the two arc plates 201. The arc plates 201 are in contact with the inner wall of the annular base 101. Annular sleeve blocks 207 are appropriately matched between the two arc plates 201. Toothed groove rings 208 are formed on the outer ring of the annular sleeve blocks 207. The toothed block groups 202 of the two arc plates 201 are respectively engaged with the inner walls on both sides of the toothed groove rings 208 of the annular sleeve blocks 207.

[0025] The purpose of this setup is that during the installation process, the annular base 101 of the fixed base 1 is first fixed in the corresponding position of the tire vulcanizing device to ensure that the annular groove 102 is placed horizontally. Then, the annular slider 203 at the bottom of the arc plate 201 on both sides of the heat insulation cover 2 is aligned with the annular groove 102 and slid in, so that the inner wall of the arc plate 201 is tightly fitted with the inner wall of the annular base 101. Next, the annular sleeve 207 is placed between the two arc-shaped plates 201, so that the toothed block group 202 at the top of the arc-shaped plate 201 precisely meshes with the toothed groove ring 208 on both sides of the outer ring of the annular sleeve 207. By rotating the annular sleeve 207, the transmission action between the toothed block and the toothed groove is used to drive the two arc-shaped plates 201 to rotate synchronously along the annular groove 102 through the annular slider 203, thereby realizing the circumferential angle adjustment of the heat insulation cover 2. After adjusting the insulation cover 2 to be aligned and matched with the feed inlet, observation window and other components of the vulcanizing device, stop rotating the annular sleeve 207. The meshing and self-locking of the toothed block group 202 and the toothed groove ring 208 can fix the position of the arc plate 201, so that the insulation cover 2 is stably covered and attached to the vulcanizing device, forming a closed insulation space, and completing the installation and angle adjustment process. The toothed ring 208 of the annular sleeve 207 meshes with the toothed block group 202 of the arc plate 201, driving the arc plate 201 to rotate along the annular groove 102 via the annular slider 203. This allows for precise adjustment of the circumferential angle of the heat insulation cover 2, facilitating its alignment with components such as the feed inlet and observation window of the vulcanizing device and avoiding structural interference.

[0026] A stainless steel cover 205 is fixedly inserted into the inner ring of the annular sleeve block 207, and an annular insert cover 206 is provided at the bottom end of the stainless steel cover 205.

[0027] The purpose of this design is to fix a stainless steel cover 205 inside the annular sleeve block 207 during the use of the structure. The high temperature resistance of stainless steel enhances the heat resistance of the core area of ​​the insulation cover 2, and avoids deformation of the cover due to high temperature of sulfidation. At the same time, the annular insert cover 206 at the bottom of the stainless steel cover 205 can form a nested fit with the components below, further strengthening the connection stability between the stainless steel cover 205 and the overall structure.

[0028] A thickened base plate 204 is fixedly connected between the two arc-shaped plates 201, and the top of the tooth block assembly 202 applies pressure to the tooth groove ring 208 of the annular sleeve block 207.

[0029] The purpose of this design is to fix a thickened base 204 between the two curved plates 201 during the use of the structure. Its heavy structure provides bottom support for the curved plates 201, enhancing the overall resistance to deformation. At the same time, the thickened base 204 applies upward support force to the curved plates 201, so that the tooth block assembly 202 continuously and tightly meshes with the tooth groove ring 208 of the annular sleeve block 207, preventing the meshing part from loosening after rotation adjustment.

[0030] The top of the thickened chassis 204 is provided with a rubber ring 209, and the outer ring of the rubber ring 209 is connected to the inner side of the two curved plates 201.

[0031] The purpose of this design is that, during the use of this structure, the outer ring of the thickened rubber ring layer 209 at the top of the chassis 204 is connected to the inner side of the two curved plates 201, which can fill the gap between the curved plates 201 and the chassis, improve the heat insulation and sealing performance, and the elastic properties of the rubber can also buffer the slight vibration when the curved plates 201 rotate, avoid direct friction and wear of metal parts, and maintain flexibility at high temperatures to prevent the gap from expanding due to thermal expansion and contraction.

[0032] The annular insert 206 is vertically inserted into the inner ring of the rubber ring layer 209, and the bottom end of the annular insert 206 is on the inner wall of the bottom surface of the thickened chassis 204.

[0033] The purpose of this design is that, during installation, the annular insert 206 at the bottom of the stainless steel cover 205 is vertically inserted into the inner ring of the rubber ring layer 209. The rubber ring layer 209 tightly wraps the outer wall of the annular insert 206 through elastic deformation, forming a sealed connection. The bottom of the annular insert 206 abuts against the inner wall of the thickened base 204. The weight of the stainless steel cover 205 is distributed by the base, preventing it from sagging due to its own weight, while also enhancing the bottom sealing of the insulation space.

[0034] The stainless steel cover 205 is provided with a positioning ring 210 at the top, and the positioning ring 210 is located in the middle of the stainless steel cover 205.

[0035] The purpose of this design is that, during the use of this structure, when the insulation cover 2 is installed as a whole, the positioning ring 210 can be fixedly connected with the clinker pipe of the tire vulcanizing device. The conveying pipe passes through the inner ring of the positioning ring 210, and the positioning ring 210 restricts the radial displacement of the clinker pipe through its own structure, so as to prevent the clinker pipe from shifting its position due to vibration or high temperature during the material conveying process.

[0036] In use, first fix the annular base 101 of the fixed base 1 to the bottom of the tire vulcanizing device, ensuring that the annular groove 102 is horizontal. Then, slide the two arc plates 201 into the annular groove 102 through the bottom annular slider 203, so that the inner wall of the arc plate 201 fits the inner wall of the annular base 101. At this time, the thickened base 204 between the two arc plates 201 forms a stable support. Place the annular sleeve block 207 pre-installed with stainless steel cover 205 between the two arc plates 201, so that the tooth block group 202 at the top of the arc plate 201 meshes with the tooth groove ring 208 of the annular sleeve block 207. Rotate the annular sleeve block 207, and drive the arc plate 201 to rotate along the annular groove 102 through the tooth transmission. Adjust the circumferential angle of the heat insulation cover 2 until it is aligned and matched with the feed inlet, observation window and other components of the vulcanizing device. During this process, the annular insert 206 at the bottom of the stainless steel cover 205 is vertically inserted into the inner ring of the rubber ring layer 209 at the top of the thickened chassis 204. The rubber ring layer 209 fills the gaps and seals them. The bottom of the annular insert 206 abuts against the chassis to enhance stability. Finally, the positioning ring 210 at the top of the stainless steel cover 205 is positioned with the top of the vulcanizing device to complete the overall installation, forming a closed high-temperature resistant insulation space, achieving precise heat preservation and protection for the tire vulcanizing process.
