[0023] Specifically, the stirring and filtering device 3 includes a fixed box 31, a fixed tube 34, an isolation assembly 35, a first motor 36 and a stirring blade 37. The fixed box 31 is installed above the two conveying pipes 4, the first motor 36 is installed below the fixed box 31 and between the two conveying pipes 4, the stirring blade 37 is installed outside the output end of the first motor 36 and inside the fixed box 31, the fixed tube 34 is installed above the fixed box 31, and isolation assemblies 35 are provided on the fixed box 31 and on both sides of the stirring blade 37.
[0024] By adopting the above technical solution, the equipment can stir the additives to a certain extent through the cooperation of the first motor 36 and the stirring blade 37 when necessary, thereby ensuring the consistency of the concentration of the additives at various locations and ensuring the normal operation.
[0025] Specifically, the stirring and filtering device 3 further includes a threaded tube 32 and a filter screen 33 . The threaded tube 32 is threadedly mounted on the outer side of the fixed tube 34 , and the filter screen 33 is mounted on the inner side of the threaded tube 32 and above the fixed tube 34 .
[0026] By adopting the above technical solution, the staff can install the threaded pipe 32 and the filter 33 therein on the fixed pipe 34 through threads when needed, and then filter the additives to a certain extent through the filter 33, so as to better meet the work needs in different situations.
[0027] Specifically, the isolation assembly 35 includes an electric telescopic rod 351 and an isolation plate 352 . The isolation plates 352 are arranged on the inner side of the fixed box 31 and on both sides of the stirring blade 37 .

[0028] By adopting the above technical solution, the equipment can prevent the additives from entering the two conveying pipes 4 through the cooperation of the electric telescopic rod 351 and the isolation plate 352 when necessary, thereby ensuring the normal stirring work.
[0029] When this embodiment is used, when the equipment is needed in PVC plastic processing, if it is necessary to filter the additive, the threaded tube 32 and the fixed tube 34 in the stirring and filtering device 3 are connected by threads, and then the additive is poured into the threaded tube 32. After being filtered by the filter screen 33, the additive passes through the fixed tube 34 and enters the fixed box 31, and then the first motor 36 is started, thereby driving the stirring blade 37 to stir the additive, so that the concentration of the additive at various places tends to be consistent, and the electric telescopic rod 351 in the two isolation components 35 is started to drive the two isolation plates 352 to move away from the stirring blade 37 until the additive can enter the two conveying pipes 4, and then the additive passes through the two connecting pipes 5 into the temporary storage box 1, and then passes through the feeding component 8 into the material guide box 7. The staff can operate the adjustment component 2 to adjust the amount of the additive entering the material guide box 7, and finally the additive enters the mixing equipment for processing, so as to be used.
[0030] Example 2
[0031] The difference between this embodiment and embodiment 1 is that the lifting and moving device 6 includes a support frame 61, a second motor 62, a moving plate 63 and a screw rod 64, a support frame 61 is arranged on the outer side of the material guide box 7, a second motor 62 is installed above the support frame 61, a screw rod 64 is installed on the side of the second motor 62 close to the support frame 61, and a moving plate 63 is installed on the material guide box 7 and at a position outside the screw rod 64 and inside the support frame 61.
[0032] By adopting the above technical solution, the equipment can adjust the height of the guide box 7 and other structures through the cooperation of the second motor 62 and the screw rod 64 and other structures when necessary, so as to better meet the working needs in different situations.
[0033] Specifically, the lifting and moving device 6 further includes a brake wheel 65 , and a plurality of brake wheels 65 are installed below the support frame 61 .
[0034] By adopting the above technical solution, the staff can move the position of the equipment to a certain extent through the brake wheel 65 when necessary, thereby reducing the difficulty of moving the equipment and further alleviating the labor burden of the staff.
[0035] When this embodiment is in use, when it is necessary to adjust the height of the material guide box 7 and other structures, the staff can start the second motor 62 in the lifting and moving device 6, thereby driving the screw rod 64 to rotate. The screw rod 64 is threadedly connected to the moving plate 63, and the moving plate 63 is close to the support frame 61, so the screw rod 64 drives the moving plate 63 to move, thereby adjusting the height of the material guide box 7 and other structures. When necessary, the staff can move the position of the equipment through the various brake wheels 65.
[0036] The structure and principle of the temporary storage box 1, the adjustment component 2 composed of an adjustment shell, an adjustment mechanism, a feed port and a limit mechanism, the material guide box 7, and the feed component 8 composed of a feed pipe and a stabilizing block in the utility model have been disclosed in a PVC plastic processing additive adding and mixing device disclosed in Chinese patent application No. 202020386620.4. Its working principle is that when in use, the material to be processed is first added to the inner cavity of the temporary storage box at one time, and then the rotating rod is rotated to drive the fixed sleeve and the fixed frame to rotate, and then the swing arm and the clamping protrusion are driven to rotate. When the clamping protrusion is clamped into the inner cavity of the clamping sleeve, the feed port can be blocked. The plug and open, then drive the adjusting roller at the bottom of the rotating rod to rotate. When the opening on the adjusting roller is aligned with the feed port, the PVC plastic in the inner cavity of the temporary storage box will enter the inner cavity of the feed pipe through the feed port and the opening on the adjusting roller, and then flow into the inner cavity of the guide box, and finally enter the mixing equipment for processing. When the opening on the rotating adjusting roller is not aligned with the feed port, the inflow of PVC plastic can be blocked. During this period, the setting of the limit mechanism can limit the rotation of the rotating rod, thereby ensuring the stability of the adjusting roller during rotation, and also ensuring the accuracy of the matching of the adjusting roller and the feed port, thereby achieving the purpose of controlling and adjusting the feeding of PVC plastic.
[0037] The working principle and use process of the utility model are as follows: when the equipment is needed in PVC plastic processing, if the additive needs to be filtered, the threaded tube 32 and the fixed tube 34 in the stirring and filtering device 3 are connected by threads, and then the additive is poured into the threaded tube 32. After being filtered by the filter screen 33, the additive passes through the fixed tube 34 and enters the fixed box 31. Then, the first motor 36 is started to drive the stirring blade 37 to stir the additive, so that the concentration of the additive at various places tends to be consistent. The electric telescopic rods 351 in the two isolation components 35 are started to drive the two isolation plates 352 to move away from the stirring blade 37 until the additive can enter the two delivery pipes 4. Then the additive passes through the two connecting pipes 5 into the temporary storage box 1, and then passes through the feeding component 8 into the material guide box 7. The staff can operate the adjustment component 2 to adjust the amount of additive entering the material guide box 7. Finally, the additive enters the mixing equipment for processing and then is used. When it is necessary to adjust the height of the structure such as the material guide box 7, the staff can start the second motor 62 in the lifting and moving device 6, thereby driving the screw rod 64 to rotate. The screw rod 64 is threadedly connected to the moving plate 63, and the moving plate 63 is close to the support frame 61, so the screw rod 64 drives the moving plate 63 to move, thereby adjusting the height of the structure such as the material guide box 7. When necessary, the staff can move the position of the equipment through each brake wheel 65.
