Description

Technical Field

[0001] This utility model relates to the field of kneading equipment technology, and in particular to a kneading machine with a preheating structure. Background Technology

[0002] A kneader is a piece of equipment used for kneading, mixing, vulcanizing, and polymerizing high-viscosity, elastic-plastic materials. It is widely used in industries such as rubber, plastics, food, and pharmaceuticals.

[0003] In existing technologies, pharmaceutical kneaders typically employ localized heating, followed by agitation by a stirring paddle to ensure thorough mixing of materials within the kneader, reducing viscosity and improving product quality. However, localized heating can lead to uneven heating, potentially causing localized overheating or delayed heating of inner layers, thus reducing the quality of the kneaded product and failing to meet the requirements for subsequent product use. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a kneading machine with a preheating structure.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a kneader with a preheating structure includes a base, a mounting plate fixed to the top of the base, an outer sleeve provided on the mounting plate, an inner sleeve provided inside the outer sleeve, a spiral electric heating wire sleeved on the outer wall of the inner sleeve, a feed pipe communicating with the inner sleeve provided on the outer sleeve, a cover plate hinged to the outer wall of the outer sleeve for closing the discharge port of the inner sleeve, a stirring paddle provided inside the inner sleeve, and a drive assembly for driving the stirring paddle to rotate on the side of the inner sleeve away from the cover plate.

[0006] By adopting the above technical solution, when workers need to stir materials, they first put the prepared materials into the inner sleeve through the feed pipe, then activate the electric heating wire to heat the outer wall of the inner sleeve, covering the entire inner sleeve with heat. The inner sleeve transfers the heat to the materials, and then the driving component drives the stirring paddle to stir the materials, thus completing the stirring process. The cover plate is then opened to remove the stirred materials. This application changes the traditional method of localized heating, avoiding material deterioration caused by localized overheating and improving the quality of the stirred materials.

[0007] Furthermore, the drive assembly includes a rotating rod rotatably mounted inside the inner sleeve, a worm gear fixed on the rotating rod, a fixed plate fixed on the outer sleeve away from the cover plate, a worm rotatably mounted on the fixed plate and meshing with the worm gear, and a drive motor fixed on the side wall of the outer sleeve away from the cover plate. The stirring paddle is fixedly sleeved on the rotating rod, and the rotating rod passes through the outer sleeve near the drive motor and is fixed to the output end of the drive motor.

[0008] By adopting the above technical solution, the staff controls the drive motor, which starts and drives the worm fixed to it, the worm wheel meshing with the worm, the rotating rod fixed to the worm wheel, and the stirring paddle fixed to the rotating rod to rotate, thereby realizing the stirring of materials.

[0009] Furthermore, the base is provided with a lifting assembly for lifting the outer sleeve. The lifting assembly includes a sliding ring slidably fitted on the outer sleeve, a U-shaped block fixed to the bottom of the sliding ring, a hinge block rotatably installed between the blocks on both sides of the U-shaped block, an electric push rod fixed to the bottom of the hinge block, a fixing block fixed to the lower end of the electric push rod, and a U-shaped support block fixed to the top of the base. The fixing block is hinged between the blocks on both sides of the U-shaped support block.

[0010] By adopting the above technical solution, when the staff needs to take out the mixed material, they first control the electric push rod to push the hinge block to move upward. Since the fixed block is hinged to the U-shaped support block and the hinge block is hinged to the U-shaped block, the hinge block drives the sliding ring to slide away from the cover plate. This causes the sliding ring to drive the outer sleeve away from the cover plate to move upward. As the height changes, the material can be poured out from the inner sleeve.

[0011] Furthermore, a hinge plate is fixed to the bottom of the outer sleeve. Two hinge plates are provided and symmetrically distributed. A connecting rod is hinged between the two hinge plates. The end of the connecting rod away from the hinge plate is fixed to the side wall of the mounting plate.

[0012] By adopting the above technical solution, the hinge plate is designed so that when the electric push rod pushes the material to pour, the outer sleeve can rotate along the hinge axis on the hinge plate, which facilitates the subsequent removal of materials and improves the efficiency of the staff in removing materials.

[0013] Furthermore, a fixing rod is fixed to the top of the connecting rod, and the end of the fixing rod away from the connecting rod is fixed to the mounting plate.

[0014] By adopting the above technical solution, the setting of the fixing rod enhances the stability of the connection between the connecting rod and the mounting plate.

[0015] Furthermore, a mounting block is fixed to the bottom of the cover plate, and a bolt is threaded through the mounting block and connected to the hinge plate.

[0016] By adopting the above technical solution, workers can open the cover plate by loosening the bolts with tools, and close the cover plate by tightening the bolts.

[0017] Furthermore, a funnel tube is fixed to the top of the feed pipe, and a sealing cap is provided on the top of the funnel tube.

[0018] By adopting the above technical solution, the setting of the funnel tube improves the efficiency of material entering the inner sleeve. At the same time, the setting of the sealing cover prevents the volatiles generated when the electric heating wire heats the material from being discharged from the feed pipe, thereby improving the quality of the material after stirring.

[0019] Furthermore, a housing is provided on the side of the outer sleeve away from the cover plate, and the worm gear, fixing plate, worm and drive motor are all located inside the housing.

[0020] By adopting the above technical solution, the housing design prevents dust and other debris from falling into the drive motor, thus ensuring the stability of the entire transmission system.

[0021] In summary, this utility model has the following beneficial effects: When the staff needs to stir the material, first put the prepared material into the inner sleeve through the feed pipe, start the electric heating wire to heat the outer wall of the inner sleeve, and cover the entire inner sleeve with the heated temperature. The inner sleeve transfers the temperature to the material, and then the stirring paddle is driven by the drive component to stir the material, thus completing the stirring of the material. Open the cover plate and take out the stirred material. Attached Figure Description

The mounting plate 11 is disposed on the top of the base 1, and the outer sleeve 12 is disposed on the mounting plate 11. The inner sleeve 13 is disposed inside the outer sleeve 12, and the electric heating wire 14 is sleeved on the outer wall of the inner sleeve 13 in a spiral shape. A feed pipe 121 is provided on the outer sleeve 12, and the feed pipe 121 communicates with the inner sleeve 13. The cover plate 15 is hinged to the outer wall of the outer sleeve 12, and the cover plate 15 is used to close the discharge port of the inner sleeve 13. The stirring paddle 16 is disposed inside the inner sleeve 13, and the stirring paddle 16 is used to stir the materials.

[0026] The drive assembly 2 is located on the side of the inner sleeve 13 away from the cover plate 15 and is used to drive the agitator 16 to rotate. The drive assembly 2 includes a rotating rod 21, a worm gear 22, a fixed plate 23, a worm 24, and a drive motor 25. The rotating rod 21 is rotatably mounted inside the inner sleeve 13, and the worm gear 22 is fixed on the rotating rod 21, with the axis of the worm gear 22 coinciding with the axis of the rotating rod 21. The worm 24 is rotatably mounted on the fixed plate 23 and meshes with the worm gear 22, with the axis of the worm 24 perpendicular to the axis of the worm gear 22. The drive motor 25 is fixed on the side wall of the outer sleeve 12 away from the cover plate 15, and is used to drive the worm 24 to rotate. In this embodiment, the agitator 16 is fixedly sleeved on the rotating rod 21, and the rotating rod 21 passes through the outer sleeve 12 near the drive motor 25 and is fixed to the output end of the drive motor 25.

[0027] The lifting assembly 3 is mounted on the base 1 and is used to lift the outer sleeve 12. The lifting assembly 3 includes a sliding ring 31, a U-shaped block 32, a hinge block 33, an electric push rod 34, a fixing block 35, and a U-shaped support block 36. The sliding ring 31 is slidably fitted onto the outer sleeve 12, and the U-shaped block 32 is fixed to the bottom of the sliding ring 31. The hinge block 33 is rotatably mounted between the two blocks of the U-shaped block 32, and the electric push rod 34 is fixed to the bottom of the hinge block 33. The fixing block 35 is fixed to the lower end of the electric push rod 34, and the U-shaped support block 36 is fixed to the top of the base 1. In this embodiment, the fixing block 35 is hinged between the two blocks of the U-shaped support block 36.

[0028] When the staff needs to stir the materials, they first put the prepared materials into the inner sleeve 13 through the feed pipe 121. Then, they start the electric heating wire 14 to heat the outer wall of the inner sleeve 13, covering the entire inner sleeve 13 with the heated temperature. The inner sleeve 13 then transfers the temperature to the materials. The staff controls the drive motor 25, which starts and drives the worm gear 24 fixed to it, the worm wheel 22 meshing with the worm gear 24, the rotating rod 21 fixed to the worm wheel 22, and the stirring rod fixed to the rotating rod 21. When the paddle 16 rotates, the material is stirred. After stirring, the cover plate 15 is opened, and the operator controls the electric push rod 34 to push the hinge block 33 upward. Since the fixed block 35 is hinged to the U-shaped support block 36, and the hinge block 33 is hinged to the U-shaped block 32, the hinge block 33 drives the sliding ring 31 to slide away from the cover plate 15. This causes the sliding ring 31 to drive the outer sleeve 12 away from the cover plate 15 to move upward. As the height changes, the material can be poured out from the discharge port.

[0030] In this embodiment, a fixing rod 6 is fixed to the top of the connecting rod 5, and the end of the fixing rod 6 away from the connecting rod 5 is fixed to the mounting plate 11. The fixing rod 6 enhances the stability of the connection between the connecting rod 5 and the mounting plate 11.

[0031] In this embodiment, a mounting block 7 is fixed to the bottom of the cover plate 15, and a bolt 71 is threaded through the mounting block 7. The bolt 71 is threadedly connected to the hinge plate 4. The operator can open the cover plate 15 by loosening the bolt 71 with a tool, and close the cover plate 15 by tightening the bolt 71.

[0032] In this embodiment, a funnel tube 8 is fixed to the top of the feed pipe 121, and a sealing cap 81 is provided on the top of the funnel tube 8.
