Description

Technical Field

[0001] This invention relates to the field of rubber hose production technology, specifically a mixing device for producing rubber hoses. Background Technology

[0002] In the production process of rubber hoses, the mixing process is a crucial step, and its quality directly affects the physical properties and chemical stability of the final product.

[0003] Traditional mixing devices often struggle to achieve uniform dispersion of ingredients during addition. Ingredients tend to accumulate or reach excessively high concentrations in certain areas as they enter the mixing tank, resulting in uneven distribution of components in the final mixture. This unevenness severely impacts the physical properties of rubber hoses, such as tensile strength and abrasion resistance. For example, in some traditional devices, ingredients are poured directly into the mixing tank through simple pipes, lacking an effective dispersion mechanism. This means the dispersion of ingredients in the raw materials relies entirely on subsequent stirring, which obviously increases the difficulty and time of stirring and makes it difficult to guarantee uniform dispersion.

[0004] Based on this, a mixing device for producing rubber hoses is now provided, which can eliminate the drawback of uneven material dispersion in existing devices. Summary of the Invention

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] The core technical concept of this invention lies in using a feeding spiral blade to ensure uniform feeding of ingredients, and using a rotating block and a dispersing plate to achieve uniform dispersion of ingredients during discharge. The master-slave gear transmission drives multiple stirring rods to work, which, together with the lifting component, form a material circulation system. The cone block and scraper design effectively remove ingredients adsorbed on the surface of the cone block, significantly improving the uniformity of ingredient dispersion, stirring efficiency and mixing quality, while simplifying the operation process and reducing maintenance costs.

[0028] In one embodiment, such as Figures 1-7As shown, a mixing device for producing rubber hoses includes a fixed base 1, on which a mixing tank 11 is placed. An adjusting block 2 is slidably mounted on the front end of the fixed base 1. A height adjusting component 12 is provided on the upper end of the fixed base 1 to adjust the height of the adjusting block 2. A feeding cylinder 21 is fixed to the bottom of the end of the adjusting block 2 away from the fixed base 1. A feeding pipe 22 is fixed to the front end of the feeding cylinder 21. A conical cavity 23 is formed inside the feeding cylinder 21. A discharge port is formed through the lower end of the conical cavity 23. A feeding structure 4 for adding ingredients into the mixing tank 11 is provided inside the conical cavity 23. The lower end of the feed cylinder 21 is fixed with a fixing plate 24, which is located directly above the mixing tank 11. The lower end of the fixing plate 24 is provided with a stirring structure 5 for stirring the raw materials inside the mixing tank 11. The middle of the lower end of the fixing plate 24 is fixed with a discharge cylinder 25. The side wall of the discharge cylinder 25 is provided with a discharge port 251. The discharge port 251 is provided with a dispersing structure 6 for dispersing the ingredients. The discharge cylinder 25 is slidably installed with a cone block 8 for guiding the ingredients to the discharge port 251. The cone block 8 is provided with a scraper 9 for scraping off the ingredients adsorbed on its surface.

[0029] In this embodiment, the mixing tank 11 is first placed on the fixed base 1, and the adjusting block 2 is adjusted using the height adjusting component 12 so that the fixed plate 24 is directly above the mixing tank 11. The motor 3 drives the feeding roller 41 and feeding spiral blade 42 of the feeding structure 4 to feed the ingredients into the conical cavity 23 through the feeding pipe 22, and then into the discharge cylinder 25. When the ingredients are discharged from the discharge port 251, the dispersing structure 6, driven by the motor 3, causes the dispersing plate 65 to rotate through the multi-component transmission, so that the ingredients are evenly fed into the mixing tank 11. The cone block 8 slides in the discharge cylinder 25 to guide the ingredients to be discharged, and the scraper 95 of the scraper component 9 scrapes off the residual ingredients on the surface of the cone block 8. Finally, the motor 3 drives the main gear 51, the driven gear 52 and the stirring rod 53 of the stirring structure 5 to rotate, fully mixing the raw materials and ingredients, and completing the mixing work. The device is also equipped with a lifting component 7 to lift the material at the bottom of the mixing tank 11 to ensure that the raw materials and ingredients are fully mixed.

[0030] In an optional embodiment, the dispersing structure 6 includes a rotating block 61 rotatably mounted at the bottom of the discharge cylinder 25. A main bevel gear 62 is fixed at the middle of the lower end of the rotating block 61. Two driven bevel gears 63 are symmetrically meshed on both sides of the main bevel gear 62. The middle of the opposite ends of the two driven bevel gears 63 are respectively fixedly connected to two connecting rods 64. The end of the connecting rod 64 away from the driven bevel gears 63 extends to the outer wall of the discharge cylinder 25 and is fixedly connected to a dispersing plate 65. The dispersing plate 65 is located at the discharge port 251. The upper end of the rotating block 61 is connected to the stirring structure 5, and the lower end of the rotating block 61 is fixedly connected to the lifting member 7 through a connecting shaft 66.

[0031] It should be noted that the rotating block 61 drives the main bevel gear 62 to rotate, and the two driven bevel gears 63 will rotate synchronously. The driven bevel gears 63 then drive the connecting rod 64 and the dispersing plate 65 to rotate. The dispersing plate 65 disperses the ingredients at the discharge port 251, so that the ingredients can enter the mixing tank evenly, thereby improving the dispersion uniformity.

[0032] In an optional embodiment, the stirring structure 5 includes a rotating rod 54 fixed to the upper end of the rotating block 61. The upper end of the rotating rod 54 extends into the interior of the fixed plate 24 and is connected to the feeding structure 4. A fixing rod 512 is fixed on the rotating rod 54. A main gear 51 is rotatably installed inside the fixed plate 24. A material port 511 is opened in the middle of the main gear 51. The inner diameter of the material port 511 is slightly larger than the inner diameter of the discharge port of the conical cavity 23, and the material port 511 is located directly below the discharge port of the conical cavity 23. A fixing rod 512 is horizontally fixed on the rotating rod 54. The two ends of the fixing rod 512 are fixed to the inner wall of the material port 511. The main gear 51 meshes with several driven gears 52 rotatably installed on the fixed plate 24. The middle part of the driven gears 52 is fixed to the stirring rod 53 rotatably installed at the lower end of the fixed plate 24.

[0033] It should be noted that since the inner diameter of the feed inlet 511 is slightly larger than the inner diameter of the discharge outlet of the conical cavity 23 and is located directly below it, it can ensure that the ingredients can smoothly pass through the feed inlet 511 into the discharge cylinder 25. When the device is running, the rotating rod 54 rotates and drives the main gear 51 to rotate through the fixed rod 512. The main gear 51 then transmits power to each of the driven gears 52 through meshing with several driven gears 52, thereby driving the stirring rod 53 to rotate, thus mixing the raw materials and ingredients, greatly improving the uniformity and efficiency of the mixing.

[0034] In an optional embodiment, the feeding structure 4 includes a feeding roller 41 fixedly mounted on the upper end of the rotating rod 54. The feeding roller 41 extends into the conical cavity 23. A feeding spiral blade 42 is fixedly connected to the outer wall of the feeding roller 41. The outer wall of the feeding spiral blade 42 fits against the inner wall of the conical cavity 23. The upper end of the feeding roller 41 is fixedly connected to the output end of the motor 3 mounted on the upper end of the adjusting block 2.

[0035] It should be noted that when motor 3 starts, it drives the feed roller 41 and the feed spiral blade 42 to rotate. Since the outer wall of the feed spiral blade 42 is in close contact with the inner wall of the conical cavity 23, the ingredients move downward evenly and stably along the inner wall of the conical cavity 23 under the push of the spiral blade, avoiding the problem of the ingredients accumulating or being unevenly distributed in the conical cavity 23, and ensuring that the ingredients can enter the mixing area smoothly and in a timely manner.

[0036] The feed roller 41 drives the rotating rod 54 to rotate, thereby driving the stirring structure 5 and the dispersing structure 6 to operate.

[0037] In an optional embodiment, a cone block 8 is provided at the upper end of the rotating block 61, and a plurality of circular blocks 611 are arranged in a circular array on the outer circumference of the upper end of the rotating block 61. A plurality of circular blocks 82 are arranged in a circular array on the outer circumference of the lower end of the cone block 8. A central hole 81 is provided through the middle of the upper end of the cone block 8. The inner wall of the central hole 81 rotates and slides with the outer wall of the rotating rod 54.

[0038] It should be noted that the lower outer circumference of the cone block 8 also has several circular blocks 82 arranged in a circular array. The circular blocks 82 correspond to the circular blocks 611 to ensure that the two can cooperate well.

[0039] During the mixing stage, after the material enters the mixing drum 11, the rotating block 61 rotates. When the upper circular block 611 of the rotating block 61 contacts the lower circular block 82 of the cone block 8, the cone block 8 slides in the discharge cylinder 25. By sliding the cone block 8 up and down in the discharge cylinder 25, the material on the cone block 8 is effectively shaken off, so that the material can be more evenly dispersed into the material in the mixing drum 11, thereby improving the uniformity of mixing.

[0040] In an optional embodiment, the lifting member 7 includes a spiral rod 71 fixedly installed at the lower end of the connecting shaft 66, and a lifting spiral blade 72 is fixed to the outer wall of the spiral rod 71.

[0041] It should be noted that during the mixing process, the material at the bottom of the mixing tank 11 is lifted by the rotation of the screw rod 71 and the lifting screw blade 72, ensuring that the raw materials and ingredients are fully mixed.

[0042] In an optional embodiment, the scraper 9 includes a scraper 95 that fits against the outer wall of the cone block 8. The upper end of the scraper 95 is fixed to the slider 91. The outer wall of the slider 91 slides against the inner wall of the side groove 541. The side groove 541 is formed on the outer wall of the rotating rod 54.

[0043] The guide rod 542 is fixed vertically inside the side groove 541. The upper end of the slider 91 has a through opening 92. The inner wall of the through opening 92 slides against the outer wall of the guide rod 542. The upper end of the slider 91 is fixed with a spring 93. The upper end of the spring 93 is fixedly connected to the top of the side groove 541.

[0044] The upper end of the slider 91 is fixed with a baffle 94, and the size of the baffle 94 is larger than the opening size of the side groove 541.

[0045] It should be noted that, due to the guiding effect of the guide rod 542 and the guide port 92, the slider 91 slides stably up and down in the vertical direction, thereby ensuring that the scraper 9 can slide up and down with the cone 8 in the discharge cylinder 25 (caused by the contact and separation of the upper round block 611 of the rotating block 61 and the lower round block 82 of the cone 8).

[0046] At the same time, the elastic force of the spring 93 keeps the slider 91 under a certain pressure, thereby ensuring that the scraper 95, which is fixed to the slider 91, fits tightly against the outer wall of the cone block 8. When the mixing device is running, the motor 3 drives the rotating rod 54 to rotate, and the rotating rod 54 drives the scraper 9 to rotate, so that the scraper 95 continuously scrapes off the ingredients adsorbed on the surface of the cone block 8.

[0047] Meanwhile, the baffle 94 always prevents the material from entering the side groove 541, ensuring the stable operation of the entire scraper 9.

[0048] Through this working process, the scraper 9 can continuously and effectively scrape off the residual ingredients on the surface of the cone block 8, improving the quality and uniformity of the mixture.

[0049] The above embodiment discloses a mixing device for producing rubber hoses. In this device, the mixing barrel 11 is placed on the fixed base 1. By operating the height adjustment component 12, the adjustment block 2 is slid to a suitable height at the front end of the fixed base 1, thereby positioning the fixed plate 24 directly above the mixing barrel 11, thus preparing space for subsequent ingredient addition and mixing.

[0050] Rubber raw material is put into the mixing tank 11, and then the fixing plate 24 is placed on the top of the mixing tank 11 by operating the height adjustment component 12.

[0051] When the motor 3 is started, the motor 3 drives the feed roller 41 in the feed structure 4 to rotate. Since the feed roller 41 extends into the conical cavity 23 and the feed spiral blade 42 fixedly connected to the outer wall is in contact with the inner wall of the conical cavity 23, after the feed enters the conical cavity 23 of the feed cylinder 21 from the feed pipe 22, it moves downward evenly and stably along the inner wall of the conical cavity 23 under the push of the feed spiral blade 42, and finally falls into the discharge cylinder 25 through the discharge port at the lower end of the conical cavity 23.

[0052] After the ingredients enter the discharge cylinder 25, the dispersing structure 6 starts working when they are discharged from the discharge port 251. The motor 3 drives the rotating block 61 to rotate, and the main bevel gear 62 fixed at the lower center of the rotating block 61 rotates accordingly. The two driven bevel gears 63 symmetrically meshing on both sides of the main bevel gear 62 rotate synchronously. The driven bevel gears 63 drive the connecting rod 64 fixedly connected to them to rotate, which in turn causes the dispersing plate 65 located at the discharge port 251 to rotate, dispersing the discharged ingredients and allowing the ingredients to enter the mixing tank 11 evenly, thereby improving the dispersion uniformity of the ingredients in the raw materials.

[0053] During the mixing stage, after the material enters the mixing drum 11, the rotating block 61 rotates continuously. Several circular blocks 611 arranged in a circular array on the upper outer circumference of the rotating block 61 intermittently contact several circular blocks 82 arranged in a circular array on the lower outer circumference of the cone block 8. When circular blocks 611 contact circular blocks 82, the cone block 8 slides within the discharge cylinder 25. This up-and-down sliding motion effectively shakes off the material from the cone block 8, allowing the material to be more evenly distributed within the mixing drum 11.

[0054] The scraper component 9 functions by sliding the guide rod 542, which is vertically fixed within the side groove 541 on the outer wall of the rotating rod 54, and the guide opening 92 penetrating the upper end of the slider 91. This allows the slider 91 to slide stably up and down vertically, following the cone block 8 within the discharge cylinder 25. This movement is caused by the contact and separation of the first round block 611 and the second round block 82. Simultaneously, the elastic force of the spring 93 fixed at the upper end of the slider 91 maintains a constant pressure on the slider 91, ensuring that the scraper 95, fixed to the slider 91, is tightly pressed against the outer wall of the cone block 8. The motor 3 drives the rotating rod 54 to rotate, which in turn drives the scraper component 9 to rotate. The scraper 95 continuously scrapes away the material adsorbed on the surface of the cone block 8. The baffle 94 fixed at the upper end of the slider 91 is larger than the opening size of the side groove 541, preventing material from entering the side groove 541. This ensures the stable operation of the entire scraper component 9, continuously and effectively scraping away residual material from the surface of the cone block 8, improving the mixing quality and uniformity.

[0055] The feed roller 41 drives the rotating rod 54 to rotate. The two ends of the fixed rod 512, which is horizontally fixed on the rotating rod 54, are fixed to the inner wall of the feed inlet 511 in the middle of the main gear 51, which is rotatably installed inside the fixed plate 24. The inner diameter of the feed inlet 511 is slightly larger than the inner diameter of the discharge outlet of the conical cavity 23 and is located directly below it, which ensures that the ingredients can smoothly pass through the feed inlet 511 into the discharge cylinder 25. When the rotating rod 54 rotates, it drives the main gear 51 to rotate through the fixed rod 512. The main gear 51 meshes with several driven gears 52 rotatably installed on the fixed plate 24, transmitting power to each driven gear 52. The driven gears 52 drive the stirring rod 53, which is fixed to them in the middle, to rotate, stirring and mixing the raw materials and ingredients in the mixing tank 11, greatly improving the uniformity and efficiency of the stirring.

[0056] During the mixing process, the lifting component 7 plays a role. The spiral rod 71 fixed at the lower end of the connecting shaft 66 and the lifting spiral blade 72 fixed on its outer wall rotate, lifting the material at the bottom of the mixing tank 11 to ensure that the raw materials and ingredients are fully mixed. Through the above series of working processes, the mixing work is completed, and a uniformly mixed material is obtained for the production of rubber hoses.

[0057] Any aspects of this invention not described in detail are well-known to those skilled in the art.

[0058] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
