Description

Technical Field

[0001] This utility model relates to the field of rubber processing technology, specifically a rubber processing preheating device. Background Technology

[0002] Rubber, as an important industrial raw material, is widely used in many fields such as tire manufacturing, seal production, and rubber hose processing. The rubber processing process usually includes several key steps such as plasticizing, mixing, calendering, extrusion, molding, and vulcanization, and preheating is an indispensable and important step that plays a decisive role in the quality and efficiency of subsequent processing.

[0003] Chinese patent CN220095160U discloses a rubber processing preheating device. This device has a circular scraper ring inside the heating cylinder. When molten rubber adheres to the inner wall of the heating cylinder, a first motor is turned on, which drives the circular scraper ring to slide on the inner wall of the heating cylinder, thereby scraping off the rubber adhering to the inner wall. At the same time, a second motor is turned on, which drives the stirring shaft to rotate. The stirring shaft then drives the scraper to slide at the bottom of the heating cylinder, scraping off the rubber adhering to the bottom of the heating cylinder. The cooperation between the circular scraper ring and the scraper can make the rubber adhering to the inside of the heating cylinder fall off, thereby preventing molten rubber from adhering to the inner wall of the heating cylinder and affecting the subsequent use of the heating cylinder.

[0004] However, in the aforementioned patent, the rubber blocks near the inner wall of the heating cylinder heat up faster, while the rubber blocks far from the inner wall heat up slower, resulting in uneven heating of the entire material. This not only reduces the overall preheating efficiency but also increases the possibility of some rubber blocks melting excessively. Utility Model Content

[0005] The purpose of this invention is to provide a rubber processing preheating device that effectively solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution.

[0007] A rubber processing preheating device includes a base plate. An soaking tank and a drying tank are respectively mounted on the upper surface of the base plate, with the included angle between the soaking tank and the drying tank and the base plate's axis being 120°. A hydraulic cylinder is rotatably mounted at the center of the upper surface of the base plate. The upper surface of the base plate is provided with a rotating structure capable of driving the hydraulic cylinder to rotate at equal angles. Three cantilever arms are coaxially and equally angled at the top of the telescopic end of the hydraulic cylinder. Filter cylinders are mounted at the ends of the cantilever arms, and a feeding hole is opened at the top of the filter cylinder. A filter plate is hinged to one side of the bottom of the filter cylinder, and the filter plate is fixed to the other side of the filter cylinder by bolts.

[0008] Therefore, by placing the rubber blocks into the filter cartridge and immersing them in the hot water in the soaking tank, the hot water can fully contact the surface of each rubber block and quickly transfer heat, making each rubber block heated evenly, thereby improving the preheating efficiency. Furthermore, the preheated rubber blocks can be dried in the drying tank to remove excess moisture, without affecting subsequent use.

[0009] Furthermore, the rotating structure includes a servo motor mounted on the upper surface of the base plate, a drive gear mounted at the end of the servo motor output shaft, and a driven gear ring mounted on the outer surface of the hydraulic cylinder, which meshes with the drive gear.

[0010] Furthermore, heating coils are installed inside the walls of the soaking tub.

[0011] Furthermore, multiple annular tubes are installed on the outer surface of the drying drum. Multiple nozzles are installed coaxially and at equal angles on the inner side of the annular tubes, with the ends of the nozzles penetrating into the drying drum. A diversion pipe is connected to the outer surface of the multiple annular tubes, and an air inlet pipe is connected to the outer surface of the diversion pipe.

[0012] Furthermore, both the soaking tank and the drying tank have drain pipes connected to their outer surfaces near the bottom, and valves are installed inside the drain pipes.

[0013] Furthermore, a stirring motor is installed at the top of the filter cartridge, and the end of the stirring motor output shaft extends into the interior of the filter cartridge and is connected to a stirring shaft.

[0014] Furthermore, a water collection tank is provided on the upper surface of the base plate between the soaking tank and the drying tank.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0016] 1. This utility model involves placing rubber blocks into a filter cylinder and immersing them in hot water in a soaking tank. The hot water can fully contact the surface of each rubber block and quickly transfer heat, resulting in uniform heating of each rubber block and thus improving preheating efficiency. Furthermore, the preheated rubber blocks can be dried in a drying tank to remove excess moisture without affecting subsequent use.

[0017] 2. This utility model uses a rotating structure to drive the hydraulic cylinder to rotate at equal angles, allowing the filter cartridge to sequentially enter the soaking tank for preheating, then enter the drying tank for drying, and finally move to the outside where workers remove the rubber blocks and place the next batch of rubber blocks to be preheated into the filter cartridge. This cycle is repeated, thereby achieving continuous operation, reducing interruption time, and further improving the overall preheating efficiency. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 1-4 This utility model provides a rubber processing preheating device, including a base plate 1. An soaking tank 101 and a drying tank 102 are respectively mounted on the upper surface of the base plate 1, with the included angle between the soaking tank 101 and the drying tank 102 and the axis of the base plate 1 being 120°. A hydraulic cylinder 103 is rotatably mounted at the center of the upper surface of the base plate 1. A rotating structure 2 capable of driving the hydraulic cylinder 103 to rotate at equal angles is provided on the upper surface of the base plate 1. Three cantilever arms 104 are coaxially and equally angled mounted on the top of the telescopic end of the hydraulic cylinder 103. A filter cylinder 105 is mounted at the end of each cantilever arm 104, and a feeding hole 106 is opened at the top of the filter cylinder 105. A filter plate 107 is hinged to one side of the bottom of the filter cylinder 105, and the filter plate 107 is fixed to the other side of the filter cylinder 105 by bolts 108.

[0025] When in use, the worker first puts the rubber block to be preheated into the filter cylinder 105 through the feeding hole 106. The hydraulic cylinder 103 drives the filter cylinder 105 to descend, immersing it in the hot water in the soaking tank 101. The hot water can fully contact the surface of each rubber block and quickly transfer heat, so that each rubber block is heated evenly, thereby improving the preheating efficiency.

[0026] After preheating, the hydraulic cylinder 103 lifts the filter cartridge 105 out of the soaking tank 101. Then, the rotating structure 2 drives the filter cartridge 105 to rotate above the drying tank 102. The hydraulic cylinder 103 drives the filter cartridge 105 down and into the drying tank 102 for drying. After drying, the hydraulic cylinder 103 and the rotating structure 2 work together to transfer the filter cartridge 105 to the outside. At this time, the worker can turn the bolt 108 to open the filter plate 107. The dried rubber block falls automatically under the action of gravity, thus completing the purpose of material removal.

[0027] Because the hydraulic cylinder 103 is driven to rotate at equal angles by the rotating structure 2, the filter cartridge 105 can be sequentially entered into the soaking tank 101 for preheating, then into the drying tank 102 for drying, and finally moved to the outside where workers take out the rubber blocks and put the next batch of rubber blocks to be preheated into the filter cartridge 105. This cycle is repeated, thereby achieving the purpose of continuous operation, reducing interruption time, and further improving the overall preheating efficiency.

[0028] It is worth noting that a removable cover (not shown in the figure) is also provided on the outside of the feeding hole 106 to prevent the rubber block from floating in hot water and coming out of the feeding hole 106.

[0029] Preferably, the rotating structure 2 includes a servo motor 201 mounted on the upper surface of the base plate 1, a drive gear 202 mounted on the end of the output shaft of the servo motor 201, and a driven gear ring 203 mounted on the outer surface of the hydraulic cylinder 103, which meshes with the drive gear 202.

[0030] When the servo motor 201 is started, it drives the drive gear 202 to rotate. Since the drive gear 202 meshes with the driven gear ring 203, it can achieve the purpose of driving the hydraulic cylinder 103 to rotate.

[0031] Preferably, a heating coil is provided inside the wall of the soaking tank 101.

[0032] The heating coil uses the principle of electric heating to heat the water in the soaking tank 101, and the water temperature can be adjusted according to actual needs.

[0033] Because the rubber block is immersed and heated inside the filter cylinder 105, it can avoid contact with the inner wall of the immersion tank 101, thus preventing the rubber block from melting, ensuring the integrity of the rubber block, and ensuring uniform heating throughout.

[0034] Preferably, a plurality of annular tubes 3 are installed on the outer surface of the drying drum 102, and a plurality of nozzles 301 are installed coaxially and at equal angles on the inner side of the annular tubes 3, with the ends of the nozzles 301 penetrating into the drying drum 102. The outer surfaces of the plurality of annular tubes 3 are connected to a diversion pipe 302, and the outer surface of the diversion pipe 302 is connected to an air inlet pipe 303.

[0035] The air inlet pipe 303 is connected to the hot air blower (not shown in the figure). The hot air generated by the hot air blower enters the distribution pipe 302 through the air inlet pipe 303, and then is distributed into multiple annular pipes 3. Finally, it is sprayed out from each nozzle 301 into the interior of the drying barrel 102. When the filter cartridge 105 enters the drying barrel 102, it can be dried by the hot air in all directions, with good uniformity.

[0036] Hot air blowers are a common existing technology, so they will not be discussed in detail here.

[0037] Preferably, both the soaking tank 101 and the drying tank 102 are connected to a drain pipe 4 near their bottom outer surface, and a valve is provided inside the drain pipe 4.

[0038] The water inside the soaking tank 101 can be replaced by the drain pipe 4 and the valve, or the water dripping from the drying tank 102 can be drained.

[0039] Preferably, a stirring motor 5 is installed on the top of the filter cartridge 105, and the end of the output shaft of the stirring motor 5 extends into the interior of the filter cartridge 105 and is connected to a stirring shaft 501.

[0040] By starting the stirring motor 5, the stirring shaft 501 can be started to stir the rubber block. Stirring it during the soaking process can improve the cleaning effect, remove impurities from the surface of the rubber block, and improve its purity.

[0041] Stirring the rubber block during drying ensures that all surfaces of the rubber block are exposed to hot air, resulting in more even and faster drying.

[0042] Preferably, a water collection tank 6 is provided on the upper surface of the bottom plate 1 between the soaking tank 101 and the drying tank 102.

[0043] When the filter cartridge 105 is transferred from the soaking tank 101 to the filter cartridge 105, the dripping water can fall into the water collection tank 6, thereby avoiding the water from flowing around and polluting the surrounding environment.

[0044] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
