Description

Technical Field

[0001] This invention relates to a dust cover processing and batching device, belonging to the technical field of dust cover processing equipment. Background Technology

[0002] Dust covers can be categorized into soft dust covers, hard dust covers, and disposable dust covers. Soft dust covers (such as instrument covers and machine covers) are commonly made of PVC / PU coated fabric, Oxford cloth, or non-woven fabric. Hard dust covers (such as covers for electronic products and precision parts) are commonly made of rubber or plastic through injection molding. Disposable dust covers are commonly made of non-woven fabric or plastic film through heat sealing or sewing. Since rigid dust covers are typically used to protect mechanical joints, piston rods, precision instruments, etc., their core performance requirements determine the direction of ingredient formulation. In related technologies, the production of rigid dust covers generally requires the addition of processing aids in addition to the main raw rubber material, such as silica and kaolin. Silica particles are tiny with a huge specific surface area and are rich in silanol groups (-Si-OH). These hydroxyl groups can form strong physical adsorption and hydrogen bonding with rubber molecular chains, effectively restricting the slippage of molecular chains. Therefore, adding silica particles in the production of rigid dust covers can significantly improve the tensile strength, tear strength, tensile stress, and abrasion resistance of the vulcanized rubber. Kaolin particles have a layered structure and a smooth surface. Therefore, adding kaolin particles in the production of rigid dust covers can act as a lubricant during mixing and reduce the viscosity of the rubber compound. However, since both silica and clay are porous materials with very large specific surface areas, especially silica, its surface is rich in silanol groups (-Si-OH), which can easily adsorb water molecules in the air through hydrogen bonds, resulting in a large amount of water physically adsorbed by silica. At the same time, the internal structure of clay crystals contains a certain amount of water of crystallization. Even in powder form, it may still contain a considerable proportion (e.g., 1%-3% or even higher) of moisture. In the production of rigid dust covers using injection molding, moisture can have disastrous consequences during the high-temperature and high-pressure mixing and vulcanization processes. For example, the essence of the vulcanization reaction is that rubber molecular chains form cross-links ("bridges") under the action of vulcanizing agents (such as sulfur) and accelerators, thereby changing from a linear structure to a three-dimensional network structure and gaining elasticity. However, many accelerators (such as thiazoles and sulfenamides) and vulcanizing agents are extremely sensitive to water. Moisture will hydrolyze these key additives, causing them to become ineffective or deteriorate. This results in the final rigid dust cover product being sticky, having low strength, large permanent deformation, and failing to achieve the expected physical properties due to insufficient vulcanization, such as poor tensile strength, elasticity, and abrasion resistance. Therefore, the de-drying operation during the processing and batching of dust cover materials is essential; Summary of the Invention To solve the above-mentioned technical problems, the present invention provides a dust cover processing and batching device, which realizes the dehydration and drying of processing aids during the dust cover processing and batching process; The technical solution adopted by this invention to solve its technical problem is: A dust cover processing and batching device, the dust cover processing and batching device comprising: A stirring mechanism, comprising a stirring component and an output component; The stirring assembly includes a rotating shaft, a transfer plate, and stirring racks. The transfer plate is movably mounted on the rotating shaft, and stirring racks are symmetrically distributed on both sides of the transfer plate. The output component includes a turbine, with a rotating shaft at the turbine's center and an air outlet on the surface of the rotating shaft.

[0003] Preferably, the rotating shaft is provided with a limiting ring, a positioning block and a chassis from top to bottom. The sliding plate has a groove inside, and the sliding plate is slidably mounted on the outside of the positioning block. At the same time, a ball is movably mounted at the lower end of the sliding plate, and a ball groove adapted to the ball is formed inside the chassis.

[0004] Preferably, the dust cover processing and batching device further includes: a batching tank, the top of which is connected to a feed pipe, a heat dissipation hole installed on one side of the upper end of the batching tank, a batching chamber formed inside the batching tank, and a stirring mechanism installed inside the batching chamber; A discharge pipe is connected to one side of the lower end of the mixing tank, and a discharge valve is installed on the discharge pipe; at the same time, the bottom of the mixing tank is connected to the output box, and the turbine is installed inside the output box; one end of the output box is connected to the air supply assembly. Preferably, a material distribution plate is provided at the position where the rotating shaft connects the feed pipe and the mixing tank, and the upper end of the rotating shaft is rotatably mounted on a positioning hole plate, which is located inside the feed pipe.

[0005] Preferably, the air supply assembly includes an air heater, a hot air pump, and a cold air duct. The air inlet of the hot air pump is connected to the air outlet of the air heater, and the air outlet of the hot air pump is connected to the hot air duct. One end of the hot air duct is connected to the inside of the output box. The air outlet of the cold air duct is connected to the cold air pump, and one end of the cold air pump is connected to the inside of the output box.

[0006] Compared with the prior art, the beneficial effects of the present invention are as follows: The dust cover processing and batching device described above has the following advantages: It is equipped with a stirring mechanism, which includes a stirring component and an output component. The stirring component includes a rotating shaft, a transfer plate, and a stirring frame. The transfer plate is movably mounted on the rotating shaft, and the stirring frames are symmetrically distributed on both sides of the transfer plate. The output component includes a turbine, and a rotating shaft is provided at the center of the turbine shaft. An air outlet is provided on the surface of the rotating shaft. For example, the air supply component delivers hot air from the output box. After the hot air enters the output box, it drives the turbine to rotate. When the turbine rotates, it drives the stirring mechanism to operate, that is, the set stirring frame rotates, which is used to stir and mix the precipitated carbon black and clay mixture. At the same time, the hot air is diffused out from the air outlet and evenly distributed in different depths inside the batching chamber. Hot air drying can be achieved for materials in different positions inside the batching chamber, improving the drying effect. After the material is dried, the air supply unit then sends cold air into the output box. The cold air enters the output box and drives the turbine to rotate. When the turbine rotates, it drives the stirring mechanism to operate, that is, the set stirring frame rotates, which is used to stir and mix the material. It mixes with the cold air and achieves a closed-environment cooling operation for the dried material that still carries residual heat. This can prevent the material carrying residual heat from being directly discharged from the batching tank and exposed to the air during the cooling process. Due to the temperature difference between the inside and outside of the pile, the inside of the pile will become damp and produce water vapor, which will condense into lumps and is not conducive to the mixing of raw materials in the subsequent dust cover production. In this way, the entire dust cover processing and batching device can achieve good drying and dehydration of the silica and clay mixture, and at the same time, it can cool the silica and clay mixture with cold air in time after drying, so that the silica and clay mixture can be put into use immediately when the dust cover is processed.

Detailed Implementation

[0012] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0013] Please see Figure 1-3 The present invention provides a technical solution: A dust cover processing and batching device, the dust cover processing and batching device comprising: The stirring mechanism uses hot or cold air as a power source to stir and mix the silica, clay, or solid additives required for processing the dust cover, and to mix them in contact with hot or cold air. It is used to achieve rapid hot air drying of silica, clay, or solid additives while also achieving rapid cold air drying. The stirring mechanism includes a stirring assembly and an output assembly. The stirring assembly includes a rotating shaft 16, a transfer plate 23, and a stirring frame 19. The transfer plate 23 is movably mounted on the rotating shaft 16, and the stirring frames 19 are symmetrically distributed on both sides of the transfer plate 23. The output component includes a turbine 20, a rotating shaft 16 is provided at the shaft center of the turbine 20, and an air outlet 17 is provided on the surface of the rotating shaft 16. When hot or cold air is introduced, it drives the turbine 20 to rotate. When the turbine 20 rotates, it drives the rotating shaft 16 to rotate. When the rotating shaft 16 rotates, it drives the stirring frame 19 installed on the rotating shaft 16 to rotate. This is used to stir and mix the silica, clay, or solid additives, and to mix them with the hot or cold air. At the same time, hot or cold air enters and exits from the air outlet 17, so that hot or cold air can be provided at different depths. Please see Figure 2 and Figure 3In an embodiment of the present invention, the rotating shaft 16 is provided with a limiting ring 21, a positioning block 22 and a chassis 25 from top to bottom. The sliding plate 23 is formed inside a sliding groove, and the sliding groove formed inside the sliding plate 23 is slidably mounted on the outside of the positioning block 22. At the same time, a ball 24 is movably mounted at the lower end of the sliding plate 23, and a ball groove 26 adapted to the ball 24 is formed inside the chassis 25. In the embodiments of the present invention, when hot or cold air of different flow rates passes through, different turbulent velocities can be generated on the turbine 20, thereby causing the turbine 20 to generate different rotational speeds. At the same time that the turbine 20 generates different rotational speeds, it will drive the rotating shaft 16 to generate different centrifugal speeds, which will generate different centrifugal forces on the transfer plate 23. This allows the transfer plate 23 to slide up and down along the outside of the positioning block 22, so that the silica, clay or solid additives at different depths can be stirred and mixed evenly, and fully contacted and mixed with hot or cold air. During the later feeding process, by controlling and reducing the flow rate of hot or cold air, the centrifugal force of the rotating transfer plate 23 can be reduced, thereby causing the ball 24 installed at the lower end of the transfer plate 23 to move in a circular motion inside the ball groove 26. This reduces the rotation height of the mixing frame 19, accelerates the discharge of deposited silica, clay or solid additives, and also reduces the frictional resistance when the transfer plate 23 rotates. Please refer to Figure 13 for the feed pipe. In one embodiment of the present invention, the dust cover processing and dispensing device further includes: The mixing tank 2 has a feed pipe 1 connected to its top, which is used for feeding materials. A heat dissipation hole 3 is installed on one side of the upper end of the mixing tank 2. The heat dissipation hole 3 is used to discharge hot air or cold air, forming an air flow circulation inside the mixing tank 2 and accelerating the discharge of hot air or cold air. Meanwhile, a mixing chamber 18 is formed inside the mixing tank 2, and the stirring mechanism is installed inside the mixing chamber 18. In addition, a discharge pipe 4 is connected to one side of the lower end of the batching tank 2, and a discharge valve 5 is installed on the discharge pipe 4; the discharge pipe 4 connected to one side of the lower end of the batching tank 2 is used to discharge the dried and mixed silica, clay or solid additive materials; at the same time, the bottom end of the batching tank 2 is connected to the output box 8, and the turbine 20 is installed inside the output box 8; one end of the output box 8 is connected to the air supply component; the air supply component supplies hot or cold air from the position of the output box 8; Meanwhile, the lower end of the mixing tank 2 is provided with a support 6, and the bottom of the support 6 is equipped with a foot pad 7; the support 6 is used to support the mixing tank 2; and the foot pad 7 improves the stability of the entire mixing tank 2 when it is placed or running. In an embodiment of the present invention, when the dust cover is used to process the batching device, the silica, clay or solid additives required for the production of the dust cover are fed into the batching tank 2 from the feed pipe 1. When hot air drying is required for materials such as silica, clay, or solid additives, the air supply component delivers hot air from the output box 8. After entering the output box 8, the hot air drives the turbine 20 to rotate. When the turbine 20 rotates, it drives the stirring mechanism to operate, that is, the set stirring frame 19 rotates to stir and mix the materials. At the same time, the hot air is diffused out from the air outlet 17 and evenly distributed at different depths inside the mixing chamber 18, so that the materials at different locations inside the mixing chamber 18 can be dried by hot air. Finally, the hot air carrying water vapor is discharged from the heat dissipation hole 3. After the material is dried, the air supply component sends cold air into the output box 8. After the cold air enters the output box 8, it drives the turbine 20 to rotate. When the turbine 20 rotates, it drives the stirring mechanism to operate, that is, the set stirring frame 19 rotates, which is used to stir and mix the material and mix it with the cold air. This achieves a closed environment cooling operation for the dried material that still carries residual heat. This can prevent the material carrying residual heat from being directly discharged from the batching tank 2 and exposed to the air during the stacking and cooling process. Due to the temperature difference between the inside and outside of the stack, the inside of the stack will become damp and generate water vapor, which will condense into lumps and is not conducive to the mixing of raw materials in the subsequent dust cover production. The final processed material is discharged from position 4 of the discharge pipe; Please see Figure 2 In one embodiment of the present invention, a material distribution plate 15 is provided at the position where the rotating shaft 16 is connected to the feed pipe 1 and the mixing tank 2. The upper end of the rotating shaft 16 is rotatably mounted on the positioning plate 14, which is located inside the feed pipe 1. When the rotating shaft 16 rotates, the material distribution plate 15 will also rotate at the same time. The material distribution plate 15 can block the hot and cold air and materials rising inside the mixing tank 2 on the one hand, and can also evenly diffuse the materials conveyed from the feed pipe 1 into the mixing tank 2. When the materials fall along the inside of the mixing tank 2, they can come into contact with the hot air to achieve the initial drying operation. Please see Figure 1 In one embodiment of the present invention, the air supply assembly includes an air heater 9, a hot air pump 10, and a cold air duct 13. The air inlet of the hot air pump 10 is connected to the air outlet of the air heater 9, and the air outlet of the hot air pump 10 is connected to the hot air duct 11. One end of the hot air duct 11 is connected to the inside of the output box 8. The air outlet of the cold air duct 13 is connected to the cold air pump 12, and one end of the cold air pump 12 is connected to the inside of the output box 8. When hot air needs to be introduced into the mixing tank 2, the air heater 9 and the hot air pump 10 are started simultaneously. The air heater 9 heats the outside natural air to become hot air, and the hot air pump 10 operates to transport the hot air through the hot air pipe 11 to the output box 8. Inside the mixing tank 2, the hot air is lifted from bottom to top to perform hot air drying on the material. When it is necessary to introduce cold air into the mixing tank 2, the cold air pipe 13 is started. The cold air pipe 13 operates to introduce outside natural air and deliver it to the mixing tank 2 through the cold air pump 12. Inside the mixing tank 2, the air is lifted from bottom to top to quickly cool the material. The workflow of this embodiment is as follows: When drying silica, clay or solid additives with hot air, start the hot air pump 10. The hot air pump 10 sends hot air into the output box 8. After the hot air enters the output box 8, it drives the turbine 20 to rotate. When the turbine 20 rotates, it drives the stirring mechanism to run, stirring and mixing the material. The hot air carrying water vapor is discharged from the heat dissipation hole 3. After the material is dried, the cold air pipe 13 is then started. Cold air is sent into the output box 8 through the cold air pipe 13. After the cold air enters the output box 8, it drives the stirring mechanism to operate, thereby achieving a closed-environment cooling operation for the dried material that still carries residual heat. The final processed material is discharged from position 4 of the discharge pipe; Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
