Description

Technical Field

[0001] This invention relates to the field of rubber vulcanization technology, specifically a vulcanizing machine for rubber tire production. Background Technology

[0002] Vulcanized rubber refers to rubber that has undergone vulcanization. It possesses properties such as non-stickiness and resistance to breakage, and is used to make most rubber products. Vulcanized rubber is also called cured rubber, commonly known as rubber or rubber sheet. After vulcanization, a three-dimensional structure forms within the raw rubber, resulting in high elasticity, heat resistance, tensile strength, and insolubility in organic solvents. Vulcanization is the process of adding vulcanizing agents and cross-linking aids such as accelerators to rubber, transforming linear macromolecules into a three-dimensional network structure under specific temperature and pressure conditions. Because sulfur was initially used to achieve cross-linking of natural rubber, it is called vulcanization.

[0003] Patent application CN117774188A discloses a feeding and heating mechanism for a rubber vulcanizing machine, including a vulcanizing mechanism, a preheating mechanism, and a conveying mechanism. The vulcanizing mechanism includes a container and a feeding cylinder. The feeding cylinder is fixedly installed on the outer wall of the container, and its inner cavity is connected to the inner cavity of the container. The preheating mechanism includes a transmission cylinder and a preheating box. The radial outer wall of the transmission cylinder has ventilation holes. The transmission cylinder is rotatably installed in the inner cavity of the feeding cylinder, and its inner cavity is connected to the inner cavity of the container. The preheating box is fixedly installed on the outer wall of the feeding cylinder. The conveying mechanism includes a drive assembly and a conveying blade. The conveying blade is spirally fixedly installed on the radial outer wall of the transmission cylinder. The rotation of the transmission cylinder is controlled by the drive assembly. A stirring motor is fixedly installed on the upper end face of the container. The above structure can improve the utilization rate of energy and materials during vulcanization, reduce operating costs, and improve vulcanization efficiency.

[0004] However, the rubber vulcanizing machines disclosed above generally have a low degree of automation and low processing efficiency. They cannot automatically preheat and feed the raw materials. Furthermore, after vulcanization, the temperature of the rubber is too high. When using conventional cooling methods, dust and impurities in the air will contaminate the quality of the rubber. Therefore, there is a lack of a cooling mechanism with a filtration structure to improve the quality of the rubber. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This invention enables efficient vulcanization of rubber granules using a vulcanization chamber. When the inner slot moves to the position of the inner vent hole and the outer slot moves to the position of the outer vent hole, the fixed and moving feed ports are misaligned. At this time, the high-temperature exhaust gas in the vulcanization chamber preheats the raw materials and vulcanizing agent through the inner and outer vent holes. When both the inner and outer slots move to the position misaligned with the inner and outer vent holes, the fixed and moving feed ports coincide. The preheated raw materials and vulcanizing agent then fall into the vulcanization chamber below through the fixed and moving feed ports. When the fan starts, a negative pressure is created inside the cooling cylinder, allowing external air to enter the air intake chamber. With the cooperation of the fan and external airflow, the vulcanized rubber can be simultaneously cooled from both the inside and outside. This design improves the safety and practicality of the vulcanizing machine used in rubber tire production.

[0018] 2. This invention performs preliminary filtration of external air through an external purification port, causing larger impurities to adhere to the outer wall of the intake ring. Air within the intake chamber is diverted to the main and secondary filters, where smaller impurities adhere to their outer walls. As the cleaning gear ring rotates, the brush reciprocates to clean the main filter, causing impurities to adhere to the brush and rotate with it. When the cleaning brush rotates to the branch air chamber, the airflow guides the impurities into the branch air chamber and stores them in the collection chamber. This design improves the stability and flexibility of the vulcanizing machine used in rubber tire production. Attached Figure Description

Detailed Implementation

[0039] The following will be combined with the appendix Figures 1 to 15 The technical solutions of the present invention have been clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] This invention provides, through improvements, a vulcanizing machine for rubber tire production, such as... Figures 1-15As shown, the vulcanizing chamber includes a vulcanizing chamber 1, a top cover 2, and a cooling mechanism 7. The top cover 2 is installed on the top of the vulcanizing chamber 1. The top of the top cover 2 is provided with a coaxial outer preheating ring cavity 201 and an inner preheating ring cavity 203. Multiple sets of fixed discharge ports 205 are opened on the top cover 2 between the outer preheating ring cavity 201 and the inner preheating ring cavity 203. A linkage frame 208 is movably installed on the top of the top cover 2. The linkage frame 208 includes an inner meshing wall 209 that cooperates with the inner preheating ring cavity 203 and an outer meshing wall 210 that cooperates with the outer preheating ring cavity 201. When the linkage frame 208 rotates, the functions of preheating and discharging rubber raw materials can be switched. The cooling mechanism 7 is fixedly installed at the bottom of the vulcanizing chamber 1. The cooling mechanism 7 includes a cooling cylinder 701 and a bottom cover 702. The bottom of the vulcanizing chamber 1 is provided with multiple sets of feeding pipes 5 located inside the cooling cylinder 701. The cooling cylinder 701 has an annular air inlet chamber 703 inside. Multiple sets of air inlets 704 communicating with the air inlet chamber 703 are opened at intervals on the outer wall of the cooling cylinder 701. The inner wall of the air inlet chamber 703 is equipped with a main filter screen 709. The cooling cylinder 701 also has a branch air chamber 716 communicating with the air inlet chamber 703 inside. The bottom cover 702 has a receiving chamber 717 communicating with the branch air chamber 716 inside. The inner wall of the receiving chamber 717 is equipped with a secondary filter screen 718. The bottom of the vulcanizing chamber 1 is provided with a fan 10. Multiple sets of feeding pipes 5 are located around the fan 10. The fan 10 and the cooling cylinder 701 cooperate to cool the vulcanized rubber synchronously from both inside and outside.

[0041] In this embodiment, the vulcanizing machine for rubber tire production mainly consists of three parts: a vulcanizing chamber 1, a top cover 2, and a cooling mechanism 7. When using the equipment, rubber granules and vulcanizing agent are first placed into the vulcanizing chamber 1, and the heating mechanism 11 is activated. Then, the linkage frame 208 is rotated by adjusting the motor 217. When the inner slot 211 moves to the position of the inner exhaust port 204, and the outer slot 212 moves to the position of the outer exhaust port 202, the fixed discharge port 205 is misaligned with the moving discharge port 213. At this time, the high-temperature exhaust gas in the vulcanizing chamber 1 preheats the raw materials and vulcanizing agent through the inner exhaust port 204 and the outer exhaust port 202. After the raw materials in the vulcanizing chamber 1 are vulcanized, the control valve 6 and the fan 10 are activated. The vulcanized rubber is discharged downwards through multiple sets of discharge pipes 5. At this time, a negative pressure is formed in the cooling cylinder 701 under the action of the fan 10. External air enters the air intake chamber 703. With the cooperation of the fan 10 and the external air force, the vulcanized rubber can be cooled simultaneously from both the inside and outside. After the rubber in the vulcanizing chamber 1 is completely discharged, the linkage frame 208 is rotated by adjusting the motor 217. When the inner slot 211 moves to a position that is misaligned with the inner exhaust port 204, and the outer slot 212 moves to a position that is misaligned with the outer exhaust port 202, the fixed discharge port 205 and the moving discharge port 213 coincide. At this time, the preheated raw materials and vulcanizing agent fall into the vulcanizing chamber 1 below through the fixed discharge port 205 and the moving discharge port 213.

[0042] See appendix Figure 2 -Appendix Figure 5 Multiple sets of external vent holes 202 are provided on the inner wall of the outer preheating ring cavity 201, multiple sets of internal vent holes 204 are provided on the outer wall of the inner preheating ring cavity 203, multiple sets of internal slots 211 that cooperate with the internal vent holes 204 are provided on the inner meshing wall 209, and multiple sets of external slots 212 that cooperate with the external vent holes 202 are provided on the outer meshing wall 210; multiple sets of moving discharge ports 213 that cooperate with the fixed discharge port 205 are provided between the inner meshing wall 209 and the outer meshing wall 210.

[0043] In this embodiment: when the inner slot 211 moves to the position of the inner vent 204 and the outer slot 212 moves to the position of the outer vent 202, the fixed discharge port 205 and the moving discharge port 213 are misaligned. At this time, the high-temperature exhaust gas in the vulcanizing chamber 1 preheats the raw materials and vulcanizing agent through the inner vent 204 and the outer vent 202. When the inner slot 211 moves to the position misaligned with the inner vent 204 and the outer slot 212 moves to the position misaligned with the outer vent 202, the fixed discharge port 205 and the moving discharge port 213 coincide. At this time, the preheated raw materials and vulcanizing agent fall into the vulcanizing chamber 1 below through the fixed discharge port 205 and the moving discharge port 213.

[0044] See appendix Figure 2 An adjusting gear ring 214 is fixedly installed on the outer wall of the linkage frame 208, and an adjusting motor 217 is installed on the top of the top cover 2. A drive gear 218 that cooperates with the adjusting gear ring 214 is installed at the output end of the adjusting motor 217.

[0045] In this embodiment: In order to drive the linkage frame 208 to rotate automatically, thereby realizing the conversion between the preheating and feeding functions of the rubber raw material, an adjustable motor 217 is designed.

[0046] See appendix Figure 2 -Appendix Figure 5 The top of the outer preheating ring cavity 201 is provided with an outer T-slot 206, and the top of the inner preheating ring cavity 203 is provided with an inner T-slot 207; the top of the inner meshing wall 209 is provided with an inner T-slot seat 216 that mates with the inner T-slot 207, and the top of the outer preheating ring cavity 201 is provided with an outer T-slot seat 215 that mates with the outer T-slot 206.

[0047] In this embodiment: when the linkage frame 208 rotates along the top cover 2, in order to improve the stability during rotation, an outer T-slot 206 and an inner T-slot 207 structure that cooperate with each other are designed.

[0048] See appendix Figure 1 -Appendix Figure 2Multiple sets of support legs 3 are fixedly installed on the outer wall of the vulcanizing chamber 1, and a control panel 4 is also installed on the outer wall of the vulcanizing chamber 1; a control valve 6 is installed in the middle of the feed pipe 5, and multiple sets of heating mechanisms 11 are installed on the inner wall of the vulcanizing chamber 1.

[0049] In this embodiment: a heating mechanism 11 is designed to heat and pressurize the vulcanizing chamber 1. A control valve 6 is designed to control the opening and closing of the feed pipe 5 so as to cool down the rubber after vulcanization.

[0050] See appendix Figure 7 -Appendix Figure 9 The inner wall of the air intake chamber 703 is provided with a rotating groove 705, and an air intake ring 706 is rotatably arranged in the rotating groove 705. The air intake ring 706 is provided with a plurality of external purification holes 707 that cooperate with the air intake port 704 at intervals, and the outer wall of the air intake ring 706 is provided with a plurality of protrusions 708.

[0051] In this embodiment: a rotating groove 705 is designed to install the air intake ring 706 and ensure its rotation on the inner wall of the air intake chamber 703. A protrusion 708 structure is designed to facilitate the rotation of the air intake ring 706. When the equipment is off, the air intake ring 706 is rotated, concealing the external purification hole 707. When the air intake ring 706 rotates, the air inlet 704 on the cooling cylinder 701 scrapes against the air intake ring 706, thus cleaning off larger impurities adhering to the external purification hole 707.

[0052] See appendix Figure 10 -Appendix Figure 12 The cooling cylinder 701 also has a rotating chamber 710 located on the side of the air inlet chamber 703. A cleaning gear ring 711 is rotatably arranged inside the rotating chamber 710. Multiple sets of brushes 712 that cooperate with the main filter 709 are arranged on the inner side of the cleaning gear ring 711. A drive chamber 713 communicating with the rotating chamber 710 is arranged on the outer wall of the cooling cylinder 701. A cleaning motor 714 is installed inside the drive chamber 713. A main gear 715 that meshes with the cleaning gear ring 711 is installed at the output end of the cleaning motor 714.

[0053] In this embodiment: when the cleaning motor 714 drives the cleaning gear ring 711 to rotate, the brush 712 reciprocates to clean the main filter 709, and impurities adhere to the brush 712 and rotate with it. When the brush 712 rotates to the position of the branch air chamber 716, the airflow from the air inlet chamber 703 into the branch air chamber 716 will guide the impurities into the branch air chamber 716 and store them in the receiving chamber 717.

[0054] See appendix Figure 10 and attached Figure 13 -Appendix Figure 15The cooling cylinder 701 has multiple positioning grooves 722 on its side, and a locking groove 723 communicating with the positioning groove 722 is provided on the inner side of the positioning groove 722. Multiple inserts 724 are fixedly installed on the top of the bottom cover 702. The inserts 724 include a vertical part 725 and a horizontal part 726. Multiple telescopic cavities 727 located on the side of the vertical part 725 are provided inside the bottom cover 702. Locking blocks 729 are movably installed in the telescopic cavities 727. A through screw hole 728 is also provided at the bottom of the telescopic cavity 727. A bolt 730 is threaded in the screw hole 728. The bottom end of the bolt 730 abuts against the locking block 729.

[0055] In this embodiment: when the bottom cover 702 needs to be installed, first rotate the bottom cover 702 clockwise. When the horizontal part 726 is inserted into the locking groove 723, the initial locking is completed. Then rotate the bolt 730 inward. At this time, the locking block 729 moves outward along the telescopic cavity 727 and locks the vertical part 725 and the positioning groove 722 again.

[0056] See appendix Figure 15 The locking block 729 has multiple sets of mounting holes 731 inside, and a return spring 732 is installed in the mounting hole 731. The outer side of the return spring 732 is connected to the inner wall of the telescopic cavity 727.

[0057] In this embodiment: when internal maintenance of the cooling cylinder 701 is required, first rotate the bolt 730 outward. At this time, under the action of the return spring 732, the locking block 729 disengages from the vertical part 725 and the positioning groove 722 and retracts into the telescopic cavity 727. Then rotate the bottom cover 702, and the horizontal part 726 can be quickly unlocked after disengaging from the locking groove 723.

[0058] See appendix Figure 2 and attached Figure 13 -Appendix Figure 14 The outer side of the receiving cavity 717 is provided with a slag discharge port 719, and an arc plate 720 is slidably installed on the outer side of the slag discharge port 719; a discharge port 721 is provided on the bottom cover 702; a stirring motor 8 is also installed in the middle of the top cover 2, and a spiral shaft 9 is provided at the output end of the stirring motor 8.

[0059] In this embodiment, impurities cleaned off the main filter screen 709 by the brush 712 and impurities on the secondary filter screen 718 are stored in the receiving cavity 717. A movable arc plate 720 is designed to facilitate timely cleaning of its interior. A discharge port 721 is designed to discharge the cooled rubber and create negative pressure inside the cooling cylinder 701, thereby introducing external air for cooling. A spiral shaft 9 is designed to further improve vulcanization efficiency.

[0060] The working principle of this invention is as follows: When using the equipment, rubber granules and vulcanizing agent are first placed into the vulcanizing chamber 1, and the heating mechanism 11 is activated. Then, the linkage frame 208 is rotated by adjusting the motor 217. When the inner slot 211 moves to the position of the inner exhaust port 204, and the outer slot 212 moves to the position of the outer exhaust port 202, the fixed discharge port 205 and the moving discharge port 213 are misaligned. At this time, the high-temperature exhaust gas in the vulcanizing chamber 1 preheats the raw materials and vulcanizing agent through the inner exhaust port 204 and the outer exhaust port 202. After the raw materials in the vulcanizing chamber 1 have vulcanized, the control valve 6 and the fan 10 are activated. The vulcanized rubber is discharged downwards through multiple sets of discharge pipes 5. At this time, a negative pressure is formed in the cooling cylinder 701 under the action of the fan 10. External air enters the air inlet chamber 703. At this time, with the cooperation of the fan 10 and the external wind, the vulcanized rubber can be simultaneously cooled from both the inside and outside. After the rubber in the vulcanizing chamber 1 is completely discharged, the linkage frame 208 is driven to rotate by adjusting the motor 217. When the inner slot 211 moves to a position that is misaligned with the inner vent 204 and the outer slot 212 moves to a position that is misaligned with the outer vent 202, the fixed discharge port 205 and the moving discharge port 213 coincide. At this time, the preheated raw materials and vulcanizing agent fall into the vulcanizing chamber 1 below through the fixed discharge port 205 and the moving discharge port 213.
