Detailed Implementation

[0021] 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.

[0022] Example

[0023] Depend on Figure 1-3 A mixing device for PVC profiles is provided, comprising a support frame 1;

[0024] A mixing tank 2 is installed on the upper surface of the support 1, and a mixing cavity is formed inside the mixing tank 2;

[0025] The mixing tank 2 is equipped with a mixing assembly 3; wherein, the mixing assembly 3 includes two bearing seats 31 disposed in the mixing tank 2, each bearing seat 31 is equipped with a bearing ring 32, and a threaded screw 33 is rotatably disposed between the two bearing rings 32.

[0026] A screw nut 34 is externally engaged with the screw nut 33, and a stirring toothed disc 35 is sleeved on the outside of the screw nut 34.

[0027] Both ends of the threaded screw 33 are provided with several connecting shafts 36, and two spiral stirring strips 37 are installed around the outside of the several connecting shafts 36.

[0028] In this embodiment, during actual use, the interaction and cooperation of multiple structures within the stirring assembly 3 enable the toothed stirring disc 35 to fully agitate the PVC profile along the stroke range of the threaded screw 33. Simultaneously, while the stirring disc 35 is agitating, the two spiral stirring strips 37 further agitate the PVC profile. Compared to traditional single-rotation stirring, the stirring assembly 3 of this application can agitate the PVC profile material in multiple directions, ensuring that different components are fully mixed and avoiding material stratification or sedimentation. At the same time, the spiral stirring strips 37 can provide sufficient shear force and effectively push the PVC material in different directions, promoting uniform dispersion between additives and main materials, thereby significantly improving stirring efficiency and effect.

[0029] Specifically, refer to Figure 2-3 Both spiral stirring bars 37 are spirally arranged and horizontally arranged along the internal cavity of the mixing box 2; both ends of the two spiral stirring bars 37 are installed at the end of the connecting shaft 36; the stirring toothed disc 35 is disc-shaped and consists of a disc and several teeth; the several teeth are arranged perpendicular to the disc and are staggered between adjacent teeth.

[0030] In this embodiment, the spiral stirring bar 37 can effectively push the PVC material in different directions, promote the uniform dispersion between the additives and the main material, thereby greatly improving the stirring efficiency and stirring effect.

[0031] Furthermore, when the threaded screw 33 rotates, the screw nut 34 meshing with it can reciprocate along the stroke range of the threaded screw 33. At this time, the PVC profile in the mixing box 2 can be stirred by the interlaced teeth formed on the outside of the stirring toothed disc 35, and the air bubbles formed by stirring can be broken, thereby improving the stirring effect on the PVC material.

[0032] Specifically, refer to Figure 2-3 The bracket 1 is externally mounted with a housing 38, and a 39 is installed inside the housing 38. The output end of the 39 passes through the mixing tank 2 and extends to connect to one end of the threaded screw 33.

[0033] In this embodiment, the housing 38 can shield and protect the screw 39, while the screw 39 can be used to control the rotation of the lead screw 33.

[0034] Furthermore, the power supply connection method of the chassis 38 is existing technology, and the control circuit can be implemented by a person skilled in the art through simple programming. It is common knowledge in the field, and it is only used without modification. Therefore, the control method and circuit connection will not be described in detail.

[0035] Specifically, refer to Figure 1-2 Two sets of guide rod cylinders 5 are installed on the side of the mixing tank 2; the top of the mixing tank 2 is rotatably connected to the mixing tank cover 6; the two guide rod cylinders 5 are respectively located on one side of the mixing tank cover 6 and their output ends are connected to the mixing tank cover 6.

[0036] In this embodiment, the user connects two sets of guide rod cylinders 5 to an external air source and provides an output air pressure value to the guide rod cylinders 5. At this time, through the connection between the guide rod cylinders 5 and the mixing tank cover 6, the guide rod cylinders 5 can open the mixing tank cover 6, thereby exposing the mixing cavity inside the mixing tank 2. Then, the user can pour the PVC profile raw material to be mixed into the mixing tank 2. After the raw material is poured out, the user can drive the mixing tank cover 6 to close the mixing tank 2 again.

[0037] Specifically, refer to Figure 1 The bottom of the mixing tank 2 is connected to a drop trough 4.

[0038] In this embodiment, during use, the set drop trough 4 can be used to discharge materials into the mixing tank 2, thereby facilitating the user to collect the PVC material in the mixing tank 2.

[0039] The present invention relates to a mixing device for PVC profiles:

[0040] Step 1: In actual use, the user connects the two sets of guide rod cylinders 5 to an external air source and provides an output air pressure value to the guide rod cylinders 5. At this time, through the connection between the guide rod cylinders 5 and the mixing tank cover 6, the guide rod cylinders 5 can open the mixing tank cover 6, thereby exposing the mixing cavity inside the mixing tank 2. Then, the user can pour the PVC profile raw material to be mixed into the mixing tank 2. After the raw material is poured out, the mixing tank cover 6 can be driven to close again.

[0041] Step 2: When the user connects the power supply to 39, the rotation of the threaded screw 33 is driven by 39. With the rotational connection between the bearing ring 32 and the threaded screw 33, the threaded screw 33 can rotate accordingly. When the threaded screw 33 reciprocates, the screw nut 34 meshing with it can reciprocate along the stroke range of the threaded screw 33 and move linearly. Through the interlocking teeth formed on its exterior, the PVC profile in the mixing tank 2 can be stirred, and the air bubbles formed by stirring can be broken.

[0042] Step 3: When the threaded screw 33 rotates, it can also drive several connecting shafts 36 to rotate. When the connecting shafts 36 rotate, the spiral stirring strips 37 surrounding the outside of the connecting shafts 36 can also rotate, thereby further stirring the PVC material in the mixing box 2 through the spiral stirring strips 37. After the PVC profile is stirred, it can be discharged through the drop trough 4.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
