Description

Technical Field

[0001] This utility model relates to the field of PVC film processing technology, and specifically to a PVC film processing mixing device. Background Technology

[0002] PVC's main component is polyvinyl chloride, which is a slightly yellow, translucent, and glossy substance. During the PVC film processing, the main raw materials and auxiliary additives for PVC film processing need to be weighed and proportioned according to a certain ratio. Then, the weighed and proportioned main raw materials and various auxiliary additives are poured into a mixing device for mixing. Since there are many types of main raw materials and various auxiliary additives, it is easy to cause insufficient mixing when they are poured into the mixing device together. To improve the thoroughness of mixing, a longer mixing time is required.

[0003] In summary, there is a current need for a PVC film processing mixing device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a PVC film processing mixing device, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A PVC film processing mixing device includes a device body. A first conveying pipe is connected to the upper end of the device body near the right side. A first feeding hopper is fixedly connected to the upper end of the first conveying pipe. A spiral pusher is rotatably connected to the inner wall of the first conveying pipe. One end of the spiral pusher passes through the first conveying pipe and is connected to the output shaft of a first motor. Two second conveying pipes are connected to the upper end of the device body near the left side.

[0007] Furthermore, the inner wall of the second conveying pipe is rotatably connected to the second spiral pusher, the two second spiral pushers push materials in opposite directions, and the two second spiral pushers are connected to each other by a connecting shaft.

[0008] Furthermore, the second spiral feeder on one side is connected to the output shaft of the second motor, and two second feeding hoppers are fixedly connected to the upper end of the second feeding pipe.

[0009] Furthermore, the device body includes a stirrer, which is rotatably connected to the top of the device body. A toothed pulley is disposed through the outer ring of the stirrer near the top. The upper end of the stirrer is connected to the output shaft of a third motor.

[0010] Furthermore, the device body also includes a premixing chamber, which is located inside the device body near the left side. A drive shaft is rotatably connected through the top of the premixing chamber, and a toothed pulley is installed through the outer ring of the drive shaft near the upper end. The drive shaft and the agitator are connected by a toothed belt under the action of the toothed pulley.

[0011] Furthermore, the device body also includes a material collection rack, which is fixedly installed inside the premixing chamber. A material distribution rack is welded to the outer ring of the drive shaft, and the material distribution rack is arranged between the material collection racks.

[0012] This invention provides a mixing device for PVC film processing. Compared with the prior art, it has the following advantages:

[0013] Beneficial effects:

[0014] First, the main material is added to the first conveying pipe through the first feeding hopper. Under the action of the first motor and the first screw pusher, the main material is fed. At the same time, the auxiliary additives are added to the second conveying pipe through the second feeding hopper. The second motor drives the second screw pusher to push the auxiliary additives. During the feeding process, the different auxiliary additives can be pre-pushed and mixed. The auxiliary additives are added to the premixing chamber. When the auxiliary additives pass through the aggregating rack, they slide and gather inward. When they pass through the distributing rack, they disperse outward. At the same time, under the action of the third motor, the agitator and the toothed belt, the drive shaft is rotated, which in turn drives the distributing rack to rotate. The distributing rack applies a certain centrifugal force to the auxiliary additives, which further improves the premixing effect between the auxiliary additives. After the auxiliary additives are premixed, they are mixed and stirred again with the main material added into the device under the action of the agitator, making it easier for the main material and auxiliary additives to be fully mixed.

[0031] like Figures 1-7 As shown, based on the above embodiments, this embodiment further provides the following:

[0032] In this embodiment, the device body 1 includes a stirrer 101, which is rotatably connected to the top of the device body 1. A toothed pulley is disposed through the outer ring of the stirrer 101 near the top. The upper end of the stirrer 101 is connected to the output shaft of the third motor 102. The device body 1 also includes a premixing chamber 106, which is disposed near the left side of the device body 1. A drive shaft 104 is rotatably connected to the top of the premixing chamber 106. A toothed pulley is disposed through the outer ring of the drive shaft 104 near the top. The drive shaft 104 and the stirrer 101 are connected by a toothed belt 103 under the action of the toothed pulley.

[0033] The third motor 102 drives the agitator 101 to rotate and mix the premixed auxiliary materials and main materials.

[0034] Example 3

[0035] like Figures 1-7 As shown, based on the above embodiments, this embodiment further provides the following:

[0036] In this embodiment, the device body 1 also includes a material collection rack 105. The material collection rack 105 is fixedly installed inside the premixing chamber 106. The outer ring of the drive shaft 104 is welded to a material distribution rack 107, which is disposed between the material collection racks 105.

[0037] The additives are added into the premixing chamber 106. When the additives pass through the material gathering rack 105, they slide inward and gather together. When they pass through the material distributing rack 107, they disperse outward, thus achieving a certain mixing effect.

[0038] Working principle and usage process of this utility model:

[0039] In use:

[0040] Step 1: The main material is added into the first conveying pipe 2 through the first feeding hopper 3. The main material is fed by the first motor 5 and the first screw pusher 4. At the same time, the auxiliary additives are added into the second conveying pipe 6 through the second feeding hopper 10. The auxiliary additives are pushed and fed by the second screw pusher 7 driven by the second motor 9. During the feeding process, the different auxiliary additives can be pre-pushed and mixed.

[0041] Step 2: The auxiliary additives enter the premixing chamber 106. When the auxiliary additives pass through the material gathering rack 105, they slide and gather inwards, and when they pass through the material distributing rack 107, they disperse outwards, achieving a certain mixing effect. At the same time, under the action of the third motor 102, the agitator 101 and the toothed belt 103, the transmission shaft 104 is driven to rotate, thereby driving the material distributing rack 107 to rotate. The material distributing rack 107 applies a certain centrifugal force to the auxiliary additives, further improving the premixing effect between the auxiliary additives. After the auxiliary additives are premixed, they are mixed and stirred again with the main material added to the device body 1 under the action of the agitator 101, making it easier for the main material and the auxiliary additives to mix fully.
