Description

Technical Field

[0001] This utility model relates to the field of kneading machine technology, specifically a continuous anti-clogging discharge structure for a kneading machine. Background Technology

[0002] Kneaders are widely used in the chemical, food, and pharmaceutical industries for mixing and kneading high-viscosity materials.

[0003] Chinese patent CN222535766U discloses a continuous anti-clogging discharge structure for a kneader, comprising a housing, a conveying assembly, a scraping assembly, and a cleaning assembly. The housing has an inlet at the upper left side and an outlet at the lower right side. The conveying assembly is located within the housing's inner cavity, the scraping assembly is located on the lower surface of the conveying assembly, and the cleaning assembly is located to the right of the scraping assembly. This continuous anti-clogging discharge structure uses multi-stage conveying to continuously transport materials between different levels, thus buffering the discharge speed and preventing excessively fast discharge. Multi-stage conveying also prevents excessive material concentration at a single conveying level, avoiding blockages or interruptions, maintaining uniform material distribution, and reducing the risk of blockage. The scraping and cleaning assemblies promptly scrape and clean material adhering to the conveyor belt, preventing excessive accumulation of viscous material that could cause discharge blockages.

[0004] In the above technical solution, the device drives the brush roller to move back and forth through an electric push rod to clean the conveyor belt. However, after long-term use, raw materials tend to stick to the surface of the brush roller, resulting in a deviation in the cleaning effect of the brush roller.

[0005] Based on this, this utility model proposes a continuous anti-clogging discharge structure for a kneader. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model proposes a continuous anti-clogging discharge structure for a kneader, which can separate the cleaning roller from the fixed sleeve by rotating the threaded cover, making the cleaning roller easy to disassemble and replace, thus improving the practicality of the device.

[0007] The technical solution to achieve the purpose of this utility model is: a continuous anti-blocking discharge structure for a kneader, including a shell, an inlet and an outlet respectively opened on the shell, a slag discharge port fixedly connected to the shell, a plurality of rotating columns rotatably connected inside the shell, and three conveyor belts respectively sleeved between the plurality of rotating columns, and further including;

[0008] The three sliding sleeves are slidably connected inside the outer shell. Three fixed sleeves are fixedly connected to the three sliding sleeves respectively. Three cleaning rollers are respectively fitted on the three fixed sleeves. Three threaded caps are respectively threadedly connected to the three fixed sleeves.

[0009] Preferably, a protective shell is fixedly connected to the outer shell, and three motors are fixedly connected to the protective shell.

[0010] Preferably, three drive rollers are fixedly connected to the output shafts of the three motors, the three drive rollers are fixedly connected to three rotating columns, three driven rollers are rotatably connected inside the protective shell, and three belts are respectively fitted between the three drive rollers and the three driven rollers.

[0011] Preferably, three sliding columns are fixedly connected to the three driven rollers respectively, and multiple through grooves are opened in the three sliding sleeves and three fixed sleeves respectively, with the driven rollers disposed in the through grooves.

[0012] Preferably, each of the three fixed sleeves has a sliding groove, the three sliding columns are slidably connected in the three sliding grooves, and the outer shell has three scrapers fixedly connected inside.

[0013] Preferably, three limiting rings are fixedly connected to the three fixed sleeves respectively, and three sliding covers are slidably connected to the outer shell.

[0014] Compared with existing technologies, the significant advantages of this invention are:

[0015] Firstly, in this utility model, the sliding sleeve, fixed sleeve, cleaning roller, limiting ring, threaded cover and sliding cover work together. When the cleaning roller needs to be replaced, the threaded cover is rotated to separate the threaded cover from the fixed sleeve. Then the cleaning roller can be removed from the fixed sleeve for cleaning and replacement. This makes the device easy to disassemble and replace the cleaning roller, thus improving the practicality of the device.

[0016] Secondly, in this utility model, the protective shell, motor, drive roller, driven roller and belt work together to enable the motor to drive the conveyor belt to operate while driving the cleaning roller to clean the conveyor belt. It is not necessary to install a separate drive mechanism to drive the cleaning roller, thereby reducing the production cost of the device. Attached Figure Description

[0026] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be 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 protection scope of the present invention.

[0027] This utility model provides an improved continuous anti-clogging discharge structure for a kneader. The technical solution of this utility model is as follows:

[0028] like Figures 1-6 As shown, a continuous anti-clogging discharge structure for a kneader includes a shell 1, with an inlet 2 and an outlet 3 respectively opened on the shell 1. A slag discharge port 4 is fixedly connected to the shell 1. Multiple rotating columns 5 are rotatably connected inside the shell 1. Three conveyor belts 6 are respectively sleeved between the multiple rotating columns 5. The height of the three conveyor belts 6 gradually decreases from the inlet 2 to the outlet 3. The structure also includes:

[0029] The sliding sleeve 13, three sliding sleeves 13 are slidably connected to the outer shell 1. Three fixing sleeves 14 are fixedly connected to the three sliding sleeves 13 respectively. Three cleaning rollers 17 are sleeved on the three fixing sleeves 14 respectively. Three threaded caps 19 are threadedly connected to the three fixing sleeves 14 respectively. By rotating the threaded cap 19 to separate the threaded cap 19 from the fixing sleeve 14, the cleaning roller 17 can be removed from the fixing sleeve 14 for replacement, making the cleaning roller 17 of this device easy to disassemble and replace, and improving the practicability of this device.

[0030] Further, as Figures 1-4 shown, a protective shell 7 is fixedly connected to the outer shell 1. The cross-section of the protective shell 7 is in the shape of a "hui" character. Three motors 8 are fixed to the protective shell 7 by bolts.

[0031] Further, as Figures 3-5 shown, three driving rollers 9 are respectively fixedly connected to the output shafts of the three motors 8 through couplings. The three driving rollers 9 are respectively fixedly connected to the three rotating columns 5. Three driven rollers 11 are rotatably connected in the protective shell 7. The diameter of the driving roller 9 is equal to the diameter of the driven roller 11. Three belts 10 are respectively sleeved between the three driving rollers 9 and the three driven rollers 11. The driving roller 9 and the driven roller 11 rotate synchronously through the belt 10.

[0032] Further, as Figures 4-6 shown, three sliding columns 12 are respectively fixedly connected to the three driven rollers 11. A plurality of through grooves 15 are respectively formed in the three sliding sleeves 13 and the three fixing sleeves 14. The through grooves 15 on the sliding sleeve 13 are communicated with the through grooves 15 on the fixing sleeve 14. The diameter of the through groove 15 is slightly larger than the diameter of the driven roller 11. The driven roller 11 is arranged in the through groove 15.

[0033] Further, as Figure 3 and Figure 6 shown, three sliding grooves 16 are respectively formed in the three fixing sleeves 14. The three sliding columns 12 are respectively slidably connected in the three sliding grooves 16. The unfolded surface of the sliding groove 16 is in a closed ring shape, so that the fixing sleeve 14 reciprocates under the rotation of the sliding column 12. Three scraping plates 20 are fixedly connected in the outer shell 1. The upper half of the scraping plate 20 has a right-angled triangle cross-section.

[0034] Further, as Figures 1-6 shown, three limiting rings 18 are respectively fixedly connected to the three fixing sleeves 14. The diameter of the limiting ring 18 is equal to the diameter of the threaded cap 19. Three sliding covers 21 are slidably connected to the outer shell 1. The cross-section of the sliding cover 21 is in the shape of an "L".

[0035] The specific working method is as follows: Raw materials are fed into the feed inlet 2, and the motor 8 is started. Its output shaft drives the drive roller 9 to rotate, and the rotating column 5 rotates accordingly. Since the conveyor belt 6 is fitted between the rotating columns 5, the conveyor belt 6 rotates with the rotation of the rotating columns 5, moving the raw materials and transporting them until the raw materials are discharged from the discharge outlet 3. Simultaneously, the driven roller 11, under the action of the belt 10, rotates with the drive roller 9, driving the sliding column 12 to rotate. Since the sliding column 12 is slidably connected within the chute 16, and the chute 16... The unfolded surface is a closed ring, so the fixed sleeve 14 moves back and forth with the rotation of the sliding column 12, driving the cleaning roller 17 to move back and forth to clean the surface of the conveyor belt 6 and prevent the raw materials from sticking and accumulating, affecting the discharge. When the cleaning roller 17 needs to be replaced, push the sliding cover 21 to move up, and then rotate the threaded cover 19. Since the threaded cover 19 is threadedly connected to the fixed sleeve 14, the threaded cover 19 will disengage from the fixed sleeve 14 as it rotates. At this time, the cleaning roller 17 can be removed from the fixed sleeve 14 and replaced.

Matters not covered in this utility model are common knowledge to those skilled in the art.
