Description

Technical Field

[0001] This utility model relates to the field of plastic stirring and extrusion technology, specifically to a stirring rod that is easy to disassemble and clean. Background Technology

[0002] Large-scale production of plastic tableware is based on extrusion thermoforming or injection molding, with a simple and efficient process: food-grade PE / PP granules and additives are first thoroughly mixed and broken up by stirring, and then the mixture is plasticized by segmented temperature control and shearing in an extruder to form a pure and uniform melt. After filtering out impurities, the melt is output stably, laying a solid foundation for molding.

[0003] The mixer can break up clumps of raw materials and disperse them evenly during the production process, avoiding defects such as color difference and weak performance of tableware caused by uneven mixing, ensuring the consistency of product appearance and mechanics, improving the plasticization efficiency of raw materials, and adapting to large-scale production.

[0004] Addressing the problems with existing technologies:

[0005] The existing mixers are equipped with a single mixing rod. Due to the size of the blades and the mixing rod, it is inconvenient to remove them for cleaning. During the cleaning process, it is easy to cause incomplete cleaning, and the residue will contaminate the subsequent raw materials, resulting in problems such as impurities and odors on the tableware. In addition, the mixing rod is subjected to the shearing force of raw materials for a long time, which can easily lead to blade wear and deformation. The traditional fixed structure is cumbersome to disassemble, and a large number of parts need to be disassembled during maintenance, which increases the difficulty and cost of maintenance. Utility Model Content

[0025] 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.

[0026] Please see Figures 1 to 7 This utility model provides a technical solution: a stirring rod that is easy to disassemble and clean, including a stirring bucket 3, a stirring component 2 is provided inside the stirring bucket 3, a driving unit 1 is provided at the top of the stirring component 2, an extruder 4 is provided at the bottom of the stirring bucket 3, and a base 5 is provided at the bottom of the extruder 4.

[0027] With the base 5 as the supporting foundation, the extruder 4 installed at the top and the mixing hopper 3 form a material processing channel that is connected vertically. The mixing component 2 inside the mixing hopper 3 is responsible for the mixing of the raw materials, while the drive unit 1 at the top provides power output to the mixing component 2. The whole structure forms a continuous working frame, providing structural support for the mixing of plastic raw materials and subsequent plasticizing extrusion.

[0028] Please see Figure 3 and Figure 4The stirring assembly 2 includes a stirring rod 24, a three-lobed locking disc 22 fixedly connected to the top of the stirring rod 24, a locking seat 23 sleeved on the upper side of the outer surface of the stirring rod 24, the outer surface of the locking seat 23 being rotatably connected to the middle of the top of the stirring hopper 3, a locking claw 21 fixedly connected to the output end of the drive unit 1 at the top of the locking disc 22, and a plurality of stirring paddles 25 provided on the outer surface of the stirring rod 24.

[0029] The three-lobed locking disc 22 at the top of the stirring rod 24 engages with the locking claw 21 at the output end of the drive unit 1 and the locking seat 23 on the upper side of the stirring rod 24. The locking seat 23 is also rotatably connected to the middle of the top of the stirring hopper 3, which allows the power of the drive unit 1 to be transmitted to the stirring rod 24 and fixes the position of the stirring rod 24. The multiple stirring paddles 25 on the outer surface of the stirring rod 24 are used to directly contact and stir the raw materials.

[0030] Both the locking claw 21 and the locking seat 23 have a three-claw shape at the end near the locking claw 21. The locking claw 21 and the locking seat 23 can form a cylinder by engaging with the locking disc 22.

[0031] When the two engage with the trilobal engaging disc 22, they can form a complete cylindrical structure together. This engagement method not only enhances the firmness of the connection between the three, but also allows the power of the drive unit 1 to be transmitted to the stirring rod 24 more evenly, avoiding shaking due to uneven force during the stirring process.

[0032] Please see Figure 5 The stirring paddle 25 includes a blade 254. A sealing gasket 253 is provided on the outer side of the end of the blade 254 near the stirring rod 24. A tapered guide cone 251 extends integrally from the middle of the end of the blade 254 near the stirring rod 24. A locking hole 252 is provided on the outer surface of the guide cone 251.

[0033] A sealing gasket 253 is provided on the outer side of the blade 254 near the stirring rod 24 to reduce the accumulation of raw materials at the joint between the two. At the same time, a tapered guide cone 251 extends integrally from the middle of this end. A locking hole 252 is also provided on the outer surface of the guide cone 251. The guide cone 251 can help the stirring blade 25 to quickly align with the installation position, and the locking hole 252 provides a connection point for subsequent fixing with the stirring rod 24.

[0034] Please see Figure 6 and Figure 7 The stirring rod 24 includes a rod body 241 fixedly connected to the bottom end of the locking plate 22. An unlocking lever 243 is slidably connected inside the rod body 241. The top end of the unlocking lever 243 extends into the locking plate 22 and contacts the outside. An installation hole 242 is opened on the outer surface of the rod body 241 at the corresponding position of the stirring paddle 25. Several linkage rods 244 are fixedly connected to the outer surface of the unlocking lever 243.

[0035] The top of the unlocking lever 243, which is slidably connected inside the rod body 241, extends into the locking disc 22 and contacts the outside, making it convenient for operators to control. The outer surface of the rod body 241 has a mounting hole 242 corresponding to the position of the stirring paddle 25. The tapered mounting hole 242 is adapted to the guide cone 251, which can quickly align the guide cone 251. Multiple linkage rods 244 are also fixedly connected to the outer surface of the unlocking lever 243. The linkage rods 244 provide a transmission basis for subsequently driving the locking component to move and realize the fixing and unlocking of the stirring paddle 25.

[0036] Several linkage rods 244 are located above several mounting holes 242. A return spring 246 is fixedly connected to the bottom side of the end of the linkage rod 244 away from the unlocking lever 243. A locking pin 247 is fixedly connected to the bottom end of the return spring 246. A guide rod 245 is fixedly connected to the middle of the top of the locking pin 247. The top of the guide rod 245 extends through the linkage rod 244 to the outside of the linkage rod 244.

[0037] The guide rod 245 can restrict the movement direction of the locking pin 247, while the return spring 246 can provide a return force for the locking pin 247 to ensure the stability of the locked state. When the unlocking lever 243 is pulled, the linkage rod 244 will rise synchronously and then pull the locking pin 247 under the restriction of the guide rod 245 to complete the unlocking action.

[0038] Please see Figure 7 The locking pin 247 is adapted to the locking hole 252, and the side of the locking pin 247 near the agitator 25 is inclined.

[0039] When the agitator 25 is aligned with the mounting hole 242 via the guide cone 251, the locking pin 247 can be inserted into the locking hole 252 to fix the agitator 25 to the agitator rod 24. The side of the locking pin 247 closest to the agitator 25 is designed as an inclined surface. When installing the agitator 25, the guide cone 251 can push the locking pin 247 upward to compress the return spring 246 after contacting the inclined surface. The docking can be completed without additional operation, simplifying the installation steps.

[0040] Please see Figures 1 to 7 At work,

[0041] First, insert the stirring rod 24 and the locking disc 22 into the middle of the locking seat 23. Then, align the guide cone 251 of the stirring paddle 25 with the mounting hole 242 of the stirring rod 24. The guide cone 251 presses the inclined surface of the locking pin 247 to compress the return spring 246 until the locking pin 247 is engaged in the locking hole 252 to complete the fixation. Then, engage the locking claw 21 with the locking disc 22 and the locking seat 23 to form a cylinder, thus completing the assembly of the stirring assembly 2. The drive unit 1 transmits power through the locking structure to drive the stirring rod 24 and the stirring paddle 25 to rotate, stirring and mixing the raw materials in the mixing hopper 3. After mixing, the raw materials are output through the extruder 4.

[0042] When disassembly is required, remove the locking claw 21, pull the unlocking lever 243 upward, and drive the locking pin 247 to disengage from the locking hole 252 through the linkage rod 244, and remove the stirring paddle 25; separate the locking seat 23 and the locking disc 22, take out the stirring rod 24, clean each part or replace the damaged stirring paddle 25 and then reassemble.
