Description
Technical Field
[0001] This utility model relates to the technical field of mixing equipment, specifically to a raw material mixing machine for the production of plastic parts for household appliances. Background Technology
[0002] In the production of plastic parts, uniform mixing of raw materials is crucial. Traditional mixing machines often suffer from uneven mixing, especially when processing high-viscosity plastic raw materials or those containing a large amount of filler. The mixing effect is even worse, resulting in low efficiency and unstable quality of the produced plastic parts.
[0003] According to a public announcement (publication number: CN210148466U), a raw material mixing machine for plastic parts production includes a feeding hopper, a fixing ring, and a machine body. A rotating rod is rotatably mounted on the inner wall of the machine body. Symmetrical stirring blades are welded to both sides of the upper surface of the rotating rod, and the stirring blades have slotted holes. A mounting frame is bolted to the lower surface of the machine body, and a motor is mounted on the mounting frame. A drive shaft is rotatably mounted on the motor and connected to the rotating rod. An air pump is bolted to the upper surface of the machine body, with the air outlet located at the top of the inner wall of the machine body. The feeding hopper is fixed to the upper surface of the machine body by the fixing ring, and the fixing ring is fixed to the lower outer wall of the feeding hopper and the upper outer wall of the machine body by fixing bolts. This utility model has a simple structure and is easy to use, allowing raw materials to be mixed as soon as they are poured into the device, reducing mixing time, improving production efficiency, and reducing processing costs.
[0004] In the aforementioned application, the raw materials are mixed by blowing air from the outlet of an air pump. However, this mixing method has limited effect on high-viscosity plastic raw materials or those containing a large amount of filler, and the problem of uneven mixing still exists. The structure for cleaning the raw materials adhering to the inner wall of the mixing tank is also problematic because raw materials tend to remain on the inner wall of the mixing tank after long-term use. Therefore, we propose a raw material mixing machine for the production of plastic parts for household appliances. Utility Model Content

[0013] For example, in at least one embodiment of the present invention, a raw material mixing machine for producing plastic parts for household appliances is provided, which further includes: a fixing rod, wherein the fixing rod is fixedly connected to the circumferential surface of the stirring shaft, and a stop block is fixedly connected to the end of the fixing rod away from the stirring shaft, the function of which is to discharge the material at a time.
[0014] The bottom of the baffle is slidably connected to the inner bottom of the mixing tank, and the conveying pipe is located above the baffle. Its function is to increase its sealing performance and make it sealed when it is not discharging material.
[0015] The gear one and gear two cooperate with each other. The number of teeth of gear one is less than that of gear two. Its function is to increase its rotational speed, so that the pump body discharges material more efficiently and stably.
[0016] The driving gear, driven gear, gear one, and gear two are all located inside the protective cover. The side section of the stop block is set as an inclined surface, which serves as a protective function.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.
[0023] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0027] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0028] like Figures 1-5 As shown, it illustrates a raw material mixing machine for producing plastic parts for household appliances according to an embodiment of the present invention, including a base plate 1, a fixing plate 2 fixedly connected to the top of the base plate 1, a mixing tank 3 fixedly connected to the top of the fixing plate 2, a tank cover 4 provided on the top of the mixing tank 3, a mixing device 5 provided at the bottom of the mixing tank 3, and a pressurized discharge device 6 provided at the bottom of the mixing tank 3.
[0029] The stirring device 5 includes a mounting plate 501, which is fixedly connected to the side of the base plate 1. A motor 502 is fixedly connected to the top of the mounting plate 501. A drive gear 503 is fixedly connected to the output shaft of the motor 502. A stirring shaft 504 is rotatably connected through the bottom of the stirring tank 3. A driven gear 505 is fixedly connected to one end of the stirring shaft 504. A connecting block 506 is fixedly connected to the circumferential surface of the stirring shaft 504. A connecting rod 507 is fixedly connected to the circumferential surface of the connecting block 506. A sliding sleeve 508 is fixedly connected to the end of the connecting rod 507 away from the connecting block 506. A spring 509 is fixedly connected to the inner side of the sliding sleeve 508. A scraper 510 is fixedly connected to the end of the spring 509 away from the sliding sleeve 508. A fixing block 511 is fixedly connected to the circumferential surface of the stirring shaft 504. A stirring blade 512 is fixedly connected to the circumferential surface of the fixing block 511.
[0030] In some examples, the bottom of the lid 4 is fixedly connected to a limiting sleeve 7, and the inner wall of the limiting sleeve 7 is rotatably connected to the circumferential surface of the stirring shaft 504. Its function is to increase the stability of the stirring shaft 504 during stirring.
[0031] The circumferential surface of the scraper 510 is slidably connected to the inner wall of the sliding sleeve 508, and the side surface of the scraper 510 is slidably connected to the inner wall of the mixing tank 3. Its function is to scrape off the residual material on the tank wall during mixing, so that the mixing is more complete.
[0032] The driving gear 503 and the driven gear 505 mesh with each other. The driving gear 503 has fewer teeth than the driven gear 505, which achieves the effect of speed reduction and torque increase.
[0033] Two sets of stirring blades 512 are provided, symmetrically distributed along the vertical central axis of the stirring shaft 504. Two sets of scrapers 510 are also provided, symmetrically distributed along the vertical central axis of the stirring shaft 504. Their function is to more thoroughly stir the materials in the tank.
[0034] For example, such as Figures 1-5 As shown, after the operator adds the raw materials to the mixing tank 3 and closes the lid 4, the motor 502 is started. The output shaft of the motor 502 drives the drive gear 503 to rotate. Since the drive gear 503 meshes with the driven gear 505, and the number of teeth of the drive gear 503 is less than the number of teeth of the driven gear 505, the driven gear 505 rotates at a slower speed while generating a larger torque. This speed reduction and torque increase effect helps the mixing shaft 504 to better mix the raw materials. The rotation of the mixing shaft 504 drives the fixed block 511 and the mixing blade 512 to rotate. The mixing blade 512 thoroughly mixes the raw materials to ensure uniform mixing. The rotation of the mixing shaft 504 also drives the connecting block 506 and the connecting rod 507 to rotate. The rotation of the connecting rod 507 causes the sliding sleeve 508 to slide on the inner wall of the mixing tank 3. Due to the elastic force of the spring 509, the scraper 510 always stays in close contact with the inner wall of the mixing tank 3. As the sliding sleeve 508 slides, the scraper 510 scrapes off the residue on the inner wall of the mixing tank 3, ensuring the integrity of the mixing and avoiding the waste or impact on the mixing effect caused by the raw materials remaining on the inner wall of the mixing tank 3.
[0035] like Figures 1-5As shown, this invention illustrates a raw material mixing machine for producing plastic parts for household appliances, according to another embodiment of the present invention. The machine includes a pressurized discharge device 6, which comprises a conveying pipe 601 that penetrates and is fixedly connected to the bottom inner side of a mixing tank 3. A pump body 602 is fixedly connected to the circumferential surface of the conveying pipe 601. A gear 603 is fixedly connected to the input shaft of the pump body 602, and a gear 604 is fixedly connected to the circumferential surface of the output shaft of a motor 502. A regulating valve 605 is fixedly connected to the circumferential surface of the conveying pipe 601. A protective cover 606 is fixedly connected to the bottom of the mixing tank 3. The protective cover 606 serves to ensure targeted discharge of materials from the tank, thereby increasing the stability and uniformity of the discharge.
[0036] In some examples, a fixing rod 8 is fixedly connected to the circumferential surface of the stirring shaft 504, and a stop block 9 is fixedly connected to the end of the fixing rod 8 away from the stirring shaft 504, which is used to achieve the effect of timed material discharge.
[0037] The bottom of the baffle 9 is slidably connected to the inner bottom of the mixing tank 3. The conveying pipe 601 is located above the baffle 9, and its function is to increase its sealing performance and make it sealed when it is not discharging.
[0038] Gear 1 603 and gear 2 604 work together. Gear 1 603 has fewer teeth than gear 2 604. Its function is to increase its rotational speed, making the pump body 602 discharge material more efficiently and stably.
[0039] The driving gear 503, driven gear 505, gear one 603 and gear two 604 are all inside the protective cover 606. The side section of the stop block 9 is set as an inclined surface, which serves as a protective function.
[0040] For example, such as 1~ Figure 5 As shown, when motor 502 starts, in addition to driving the stirring device 5 to stir, its output shaft also drives gear 604 to rotate. Since gear 603 has fewer teeth than gear 604, gear 603 rotates at a faster speed, which in turn drives the input shaft of pump body 602 to rotate at high speed. The rotation of pump body 602 generates suction, drawing the raw material in stirring tank 3 out through conveying pipe 601. The regulating valve 605 allows operators to adjust the discharge speed and quantity as needed to meet different production requirements. When discharge is required, the baffle 9 gradually moves away from the opening of conveying pipe 601 as the stirring shaft 504 rotates, and the raw material is drawn out under the suction of pump body 602; when the stirring shaft 504 rotates to the point where the baffle 9 blocks the opening of conveying pipe 601 again, the discharge process stops, thus achieving timed discharge. The entire discharge process is stable and efficient, greatly improving production efficiency.
[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
