Description

Technical Field

[0001] The utility model relates to the field of mixing devices, in particular to a double-stirring raw material mixing device. Background Art

[0002] PVC terminals, as a common electrical connector, are mainly composed of PVC (polyvinyl chloride) materials and metal conductors. When the outer shell of PVC terminals is produced and processed, raw materials need to be mixed, so a mixing device is used, and generally a stirring tank is used for mixing operations.

[0003] When the stirring tank mixes materials, after the materials are put into the tank body, the motor is started to drive the stirring rod and the stirring blade to rotate, and the materials are mixed through the stirring blade. However, in this kind of stirring tank, only one stirring structure is used for stirring, and the stirring effect is average. To achieve the required mixing effect, long-time stirring is required, which will waste a lot of time. In some stirring tanks, two stirring structures are arranged at the top and the bottom, but these two stirring structures are driven by independent motors, which requires multiple driving sources, thus increasing the energy consumption. Moreover, a scraping structure is not arranged at the bottom of the stirring structure, and the material cannot be scraped during discharging, resulting in incomplete discharging and general use effect. Summary of the Utility Model

Specific embodiments

[0019] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Such as Figures 1 - 5As shown in the figure, a double-stirring raw material mixing device includes a device main body 1, a top cover 2 is provided on the device main body 1, and a speed reduction motor 3 is provided on the top cover 2. An opposite-direction driving structure is provided inside the top cover 2, and the opposite-direction driving structure includes a fixing frame 4, a first rotating shaft 5, a first bevel gear 6, a second rotating shaft 7, a second bevel gear 8, and a third bevel gear 9. A forward stirring frame 10 is provided at the lower end of the first rotating shaft 5, and a scraping component 11 is connected to the lower end of the forward stirring frame 10. A reverse stirring structure 12 is installed on the second rotating shaft 7. A feed pipe 13 is provided on the top cover 2, and a discharge pipe 14 is provided at the lower end of the device main body 1. Legs 15 are installed at the lower end of the device main body 1. The fixing frame 4 is fixed inside the top cover 2. The first rotating shaft 5 is composed of a thick short shaft and a thin long shaft. The thick short shaft of the first rotating shaft 5 is rotatably connected to the fixing frame 4, and the first rotating shaft 5 is connected to the speed reduction motor 3. The first bevel gear 6 is provided on the first rotating shaft 5. The second rotating shaft 7 is installed at the lower end of the fixing frame 4. The thin long shaft in the first rotating shaft 5 penetrates through the second rotating shaft 7. The second bevel gear 8 is installed on the second rotating shaft 7. The third bevel gear 9 is rotatably installed on the fixing frame 4, and the third bevel gear 9 is meshed with the first bevel gear 6 and the second bevel gear 8. By setting the opposite-direction driving structure and cooperating with the forward stirring frame 10 and the reverse stirring structure 12, a double-stirring effect exists inside the device main body 1, and these two stirrings run in opposite directions, increasing the mixing effect of the raw materials. It can not only improve the mixing uniformity but also complete the mixing in a shorter time, shortening the time. The opposite-direction driving structure synchronously drives the forward stirring frame 10 and the reverse stirring structure 12 to rotate. Using a single driving source can achieve double-stirring drive, which can reduce energy consumption to a certain extent and reduce costs.

[0021] When producing the PVC terminal housing, the raw materials are mixed. The device main body 1 is placed through the legs 15, and the raw materials are fed into the device main body 1 through the feed pipe 13. After the raw materials enter the device main body 1, the speed reduction motor 3 on the top cover 2 is started. The speed reduction motor 3 runs to drive the first rotating shaft 5 on the fixing frame 4 to rotate. The first rotating shaft 5 then drives the first bevel gear 6 and the forward stirring frame 10 to rotate, thereby stirring the raw materials inside the device main body 1. At the same time, the first bevel gear 6 drives the second bevel gear 8 to rotate in the opposite direction through the third bevel gear 9, and then drives the reverse stirring structure 12 to rotate in the opposite direction through the second rotating shaft 7. Cooperating with the forward stirring frame 10, a double-stirring effect is achieved, and the stirrings are in opposite directions, which can improve the mixing effect. During the stirring process, the thin long shaft of the first rotating shaft 5 penetrates through the second rotating shaft 7, and the two do not affect each other. While stirring and mixing, the forward stirring frame 10 also drives the scraping component 11 to rotate, and the scraping component 11 can also play a role in stirring and mixing. And after completion, the materials are discharged through the discharge pipe 14. At this time, the scraping component 11 can also scrape the materials to ensure the completeness of the discharge.

[0022] Through the above implementation scheme, the scraping component 11 includes a hexagonal groove 1101, a connecting rod 1102, a support plate 1103, a scraping rod 1104, a hexagonal rod 1105 and a spring 1106. The hexagonal groove 1101 is opened at the lower end of the forward stirring frame 10. The connecting rod 1102 is fixedly connected to the support plate 1103. The scraping rod 1104 is installed on the connecting rod 1102 and the support plate 1103. The hexagonal rod 1105 is fixed on the connecting rod 1102. The scraping component 11 is arranged at the lower end of the forward stirring frame 10, which can scrape materials during discharging to ensure the completeness of discharging. Structures such as the hexagonal groove 1101, the spring 1106 and the hexagonal rod 1105 are arranged in the scraping component 11, which can not only ensure that the scraping rod 1104 is in close contact with the inner bottom surface of the device main body 1, but also does not affect the rotating scraping effect.

[0023] When installing the scraping component 11, the connecting rod 1102 and the scraping rod 1104 are directly arranged at the inner bottom end of the device main body 1 through the support plate 1103, and the spring 1106 is arranged in the hexagonal groove 1101. After installing the top cover 2, the structures arranged on the top cover 2 synchronously enter the inside of the device main body 1. The forward stirring frame 10 is sleeved on the hexagonal rod 1105, and the upper end of the hexagonal rod 1105 contacts the spring 1106. At this time, the spring 1106 is in a compressed state. Under the action of the spring 1106, the scraping rod 1104 is in close contact with the inner bottom surface of the device main body 1, ensuring the contact scraping effect. During the rotation of the forward stirring frame 10, the hexagonal rod 1105 is used for driving, ensuring the synchronous rotation of the scraping component 11 and being able to ensure the scraping effect.

[0024] Through the above implementation scheme, the reverse stirring structure 12 includes an installation rod 1201, a round hole 1202, a rotating rod 1203, a first limiting block 1204, a second limiting block 1205 and a spiral stirring blade 1206. The installation rod 1201 is arranged on the second rotating shaft 7 through the round hole 1202. The upper end of the rotating rod 1203 penetrates through the installation rod 1201. The first limiting block 1204 and the second limiting block 1205 are installed on the rotating rod 1203. The spiral stirring blade 1206 is fixed on the rotating rod 1203. The rotating rod 1203 is installed on the installation rod 1201 through the first limiting block 1204 and the second limiting block 1205. When used in cooperation with the spiral stirring blade 1206, during the rotation of the entire reverse stirring structure 12, the spiral stirring blade 1206 can rotate through the rotating rod 1203 under force, thereby increasing the local stirring effect and further improving the mixing effect.

[0025] When installing the reverse stirring structure 12, the installation rod 1201 is arranged on the second rotating shaft 7 through the round hole 1202 and fixed by screws. The second limiting block 1205 is arranged on the rotating rod 1203. Then the upper end of the rotating rod 1203 penetrates through the hole on the installation rod 1201 until the second limiting block 1205 contacts the installation rod 1201. Just install the first limiting block 1204 at the upper end of the rotating rod 1203. At this time, the rotating rod 1203 is installed through the two limiting blocks. When the second rotating shaft 7 rotates, the installation rod 1201 drives the rotating rod 1203 and the spiral stirring blade 1206 to rotate together for stirring and mixing. At the same time, under the reverse acting force of the material, the spiral stirring blade 1206 can rotate locally through the rotating rod 1203, improving the mixing effect. The structure is simple and the use effect is good.
