Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of PVC board production and processing equipment, and in particular to a mixing device for PVC board production and processing. Background Technology
[0002] In the industrial production of PVC sheets, raw material mixing is a core pretreatment step that determines the performance of the final product. PVC sheet manufacturing typically involves processes such as raw material weighing, high-speed mixing, hot melt extrusion, calendering, and cooling. Among these, the mixing process requires mixing polyvinyl chloride resin powder with liquid additives such as plasticizers, stabilizers, and colorants in a specific ratio to form a premix with a uniform dispersion system.
[0003] Currently, the raw materials required for mixing are packaged in bags and need to be put into the mixing drum. Since most of the material is powder, powder splashing is likely to occur during manual feeding, which affects the production environment and causes injury to operators. Summary of the Invention
[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide a mixing device for PVC board production and processing that can safely feed materials, has a simple structure, and is easy to operate.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] A mixing device for PVC board production and processing includes a mixing component and a power component. The mixing component includes a mixing cylinder with a cap at the top and a discharge mechanism at the bottom. Mixing blades are installed inside the mixing cylinder and are connected to the power component. The cap has an opening, and a dustproof box is fixedly installed at the opening. Packaging bag placement platforms are symmetrically arranged at the bottom of the dustproof box. A discharge port is provided between the two packaging bag placement platforms and passes through the opening. A door is installed on one side of the dustproof box, and two perforations are provided at the top of the dustproof box, where rubber gloves are installed.
[0007] During use, open the required mixing bags and move them to the bag placement platform. Close the box door, put your hands inside rubber gloves, pour out the bags, and shake them to add material. During this process, the material enters the mixing cylinder through the discharge port and opening. Dust and droplets generated are prevented from overflowing to the outside by the dustproof box and sealed lid, ensuring a clean environment during feeding and mixing, and avoiding injury to construction personnel. Remaining bags can be placed on the placement platform and removed after mixing. During mixing, the power unit drives the mixing blades to rotate, and after mixing, the material is discharged through the discharge component. This solution has a simple structure and, through the dustproof box design, allows the feeding process to take place inside the dustproof box, preventing powder splashing, protecting the construction environment, and reducing damage to the outside world.
[0008] As an optimization, the mixing cylinder is set on the worktable, and a transmission shaft is coaxially arranged on the mixing blade. The transmission shaft is rotatably connected to the mixing cylinder and the worktable. A first pulley is coaxially driven at the bottom of the shaft. The power assembly includes a drive motor, and a second pulley is arranged on the output shaft of the drive motor. The second pulley is connected to the first pulley via a belt.
[0009] In this way, the rotation of the drive motor can drive the blades to rotate, thus completing the mixing of the raw materials in the mixing cylinder.
[0010] As an optimization, the discharge assembly includes a discharge port disposed on the bottom side of the mixing cylinder, and a "Y"-shaped discharge cylinder extending from the discharge port. The first channel of the "Y"-shaped discharge cylinder is horizontally disposed and directly opposite the discharge port, and the second channel is disposed obliquely downward. A plug that is shaped to resemble the discharge port is disposed in the first channel, and the plug is connected to the first cylinder.
[0011] In this way, during feeding and mixing, the first cylinder drives the plug to seal the outlet, preventing material from flowing out and ensuring the normal operation of mixing. After mixing is completed, the first cylinder drives the plug to open, and the material flows out through the second channel to achieve discharge.
[0012] As an optimization, a second cylinder is vertically arranged on the side wall of the mixing cylinder, and one side of the cover is rotatably mounted on the extension end of the second cylinder.
[0013] In this way, when the mixing cylinder needs to be cleaned, the second cylinder drives the cover to lift, separate it from the mixing cylinder, and rotates the cover to open the mixing cylinder, making it easier to clean the inside.
[0014] As an optimization, the top of the mixing cylinder is provided with an annular protrusion, and the bottom of the cover is provided with a clearance groove opposite to the annular protrusion.
[0015] This ensures the precision of the seal and the mixing cylinder's engagement, guaranteeing the stability of the connection during the mixing process.
[0016] As an optimization, the door is fitted with glass.
[0017] This facilitates the observation of the internal situation and ensures the smooth progress of the feeding process.
[0018] In summary, this mixing device for PVC board production and processing has the advantages of safe feeding, simple structure, and convenient operation. Attached Figure Description

[0026] like Figure 1-6As shown, a mixing device for PVC board production and processing includes a mixing component and a power component. The mixing component includes a mixing cylinder 1, a cover 11 at the top of the mixing cylinder, a discharge mechanism at the bottom, and mixing blades 12 inside the mixing cylinder. The mixing blades are connected to the power component for transmission. An opening 13 is provided on the cover, and a dustproof box 14 is fixedly installed upward at the opening. Packaging bag placement platforms 15 are symmetrically arranged at the bottom of the dustproof box. A discharge port is provided between the two packaging bag placement platforms and is connected through the opening. A door 16 is installed on one side of the dustproof box, and two through holes are provided on the top of the dustproof box. Rubber gloves 17 are installed at the through holes.
[0027] During use, open the required mixing bags and move them to the bag placement platform. Close the box door, put your hands inside rubber gloves, pour out the bags, and shake them to add material. During this process, the material enters the mixing cylinder through the discharge port and opening. Dust and droplets generated are prevented from overflowing to the outside by the dustproof box and sealed lid, ensuring a clean environment during feeding and mixing, and avoiding injury to construction personnel. Remaining bags can be placed on the placement platform and removed after mixing. During mixing, the power unit drives the mixing blades to rotate, and after mixing, the material is discharged through the discharge component. This solution has a simple structure and, through the dustproof box design, allows the feeding process to take place inside the dustproof box, preventing powder splashing, protecting the construction environment, and reducing damage to the outside world.
[0028] In this embodiment, the mixing cylinder is mounted on the workbench 18, and a drive shaft 19 is coaxially mounted on the mixing blades. The drive shaft is rotatably connected to the mixing cylinder and the workbench. A first pulley 2 is coaxially mounted at the bottom of the drive shaft. The power assembly includes a drive motor 21, and a second pulley 22 is mounted on the output shaft of the drive motor. The second pulley is connected to the first pulley via a belt 23. Thus, the rotation of the drive motor drives the blades to rotate, thereby completing the mixing of the raw materials in the mixing cylinder.
[0029] In this embodiment, the discharge assembly includes a discharge port located on the bottom side of the mixing cylinder. A "Y"-shaped discharge cylinder extends from the discharge port. A first channel 24 of the "Y"-shaped discharge cylinder is horizontally positioned and directly opposite the discharge port, while a second channel 25 is angled downwards. A plug 26, conforming to the shape of the discharge port, is disposed within the first channel and connected to a first cylinder 27. Thus, during feeding and mixing, the first cylinder drives the plug to seal the discharge port, preventing material leakage and ensuring normal mixing operation. After mixing is complete, the first cylinder opens the plug, allowing the material to flow out through the second channel, achieving discharge.
[0030] In this embodiment, a second cylinder 28 is vertically installed on the side wall of the mixing cylinder, and one side of the cover is rotatably mounted on the telescopic end of the second cylinder. Thus, when the mixing cylinder needs cleaning, the second cylinder lifts the cover, separating it from the mixing cylinder, and rotates the cover to open the mixing cylinder, facilitating internal cleaning.
[0031] In this embodiment, the top of the mixing cylinder is provided with an annular protrusion 29, and the bottom of the cap is provided with a clearance groove 3 opposite to the annular protrusion. This ensures the precision of the cap and the mixing cylinder's engagement and guarantees the stability of the connection during the mixing process.
[0032] In this embodiment, a glass panel 31 is provided on the box door. This facilitates observation of the internal situation and ensures the smooth progress of the feeding process.
[0033] Principle: Open the packaging bags required for mixing and move them to the packaging bag placement platform. Close the box door, put your hand into a rubber glove, tilt the packaging bags, and shake them to feed the material. During this process, the material enters the mixing cylinder through the discharge port and the opening. The dust and droplets generated will not overflow to the outside due to the barrier of the dustproof box and the cover. The remaining packaging bags can be placed on the placement platform. During mixing, the power component drives the mixing blades to rotate. After mixing is completed, the material is discharged through the discharge component.
[0034] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
