Description

Technical Field

[0001] The utility model relates to the technical field of PVC pipes, in particular to a batching device for producing PVC pipes. Background Art

[0002] PVC pipe refers to a pipe material made of polyvinyl chloride (Polyvinyl Chloride), which is commonly used in various piping systems such as water pipes, drainage pipes, and wire casings. This material is corrosion-resistant, wear-resistant, and not easily corroded by chemical substances. Therefore, it has been widely used in construction, engineering, and other fields. The batching device used in the production of PVC pipes is usually a mixer or mixing and stirring equipment, which is used to mix different raw materials evenly in proportion.

[0003] At present, when mixing PVC pipe materials, the batching device mainly mixes and stirs the PVC pipe materials through structures such as stirring rods. During the stirring process, the contact area between the stirring rod and the PVC pipe materials is limited, resulting in some PVC pipe materials easily accumulating together and unable to be fully mixed. Utility Model Content

[0004] The utility model aims to provide a batching device for PVC pipe production, which has the advantage of being able to turn over and mix the PVC pipe materials inside a material box to make the materials mixed more fully, thus solving the problem that the batching device cannot fully mix the PVC pipes.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a batching device for PVC pipe production, comprising a material box and a fixed sleeve, connecting plates are welded on both sides of the material box, hydraulic cylinders are installed at the bottom of the two connecting plates, bottom plates are installed at the bottom of the two hydraulic cylinders, fixing plates are welded on both sides of the bottom of the material box, casters are symmetrically rotatably installed on the opposite sides of the two fixing plates, a discharge pipe is embedded and installed at the bottom of the material box on the opposite side of the two fixing plates, a bearing is embedded and installed in the middle of the top of the material box, a screw rod is fixedly installed on the inner ring of the bearing, a servo motor is installed on the top of the material box above the screw rod, the fixing sleeve is provided with screw holes, the fixing sleeve is meshed and connected with the screw rod through the screw holes, a grid frame is installed in a ring array on the outside of the fixing sleeve, and a baffle is installed at the bottom of the screw rod.

[0006] When using a batching device for PVC pipe production in the technical solution, the material box is moved to a suitable position through the casters at the bottom of the material box, two hydraulic cylinders push the bottom plate down, so that the bottom plate contacts the ground and lifts the casters off the ground, and the bottom plate provides support for the material box, and a certain amount of PVC pipe material is added to the inside of the material box through the two feeding pipes on the top of the material box. The servo motor drives the screw rod to rotate through the transmission structure, and the fixed sleeve moves on the rotating screw rod through the screw hole. The fixed sleeve drives the grid frame to move up and down, and the grid frame flips the PVC pipe material at the bottom end of the material box upward, so that the PVC pipe material is constantly flipped and mixed together, and the baffle drives the two scrapers to rotate through the two connecting rods, and the two scrapers scrape off the PVC pipe material attached to the inner wall of the material box, and the mixed PVC pipe material inside the material box enters the discharge pipe along the two guide plates and is discharged.

[0007] Preferably, the bottom plate is provided with a movable hole, the inner diameter of the movable hole is larger than the outer diameter of the material box, so that the bottom plate will not interfere with the material box when it rises.

[0008] Preferably, two feed pipes are symmetrically embedded and installed on the top of the material box on both sides of the bearing, and the two feed pipes are connected to the inside of the material box. The PVC pipe material enters the inside of the material box from the two feed pipes.

[0009] Preferably, the servo motor transmission structure is fixedly connected to the top of the screw rod. The servo motor drives the screw rod to rotate through the transmission structure.

[0010] Preferably, a positioning rod is installed at the top of the material box on one side of the bearing, and a positioning hole is opened at the fixing sleeve on one side of the screw hole, and the bottom of the positioning rod passes through the positioning hole. The positioning rod limits the fixing sleeve, and when the fixing sleeve moves on the screw rod, it moves on the positioning rod through the positioning hole, thereby reducing the shaking of the fixing sleeve.

[0011] Preferably, connecting rods are welded on both sides of the baffle, and scrapers are installed on the opposite ends of the two connecting rods, and the two scrapers are in contact with the inner wall of the material box. When the baffle rotates, the two connecting rods drive the two scrapers to rotate, and the two scrapers scrape off the PVC pipe material attached to the inner wall of the material box.

[0012] Preferably, two guide plates are symmetrically installed at the bottom of the material box below the baffle, and the two guide plates correspond to the discharge pipe. The PVC pipe material mixed inside the material box flows along the two guide plates into the discharge pipe and is discharged.

[0013] Preferably, the bottom plate is parallel to the material box. When the bottom plate provides support force to the material box, the center of gravity of the material box will not shift.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model adds a certain amount of PVC pipe material into a material box by arranging a fixing sleeve and a grid frame, the servo motor drives the screw rod to rotate through the transmission structure, the fixing sleeve moves on the rotating screw rod through the screw hole, the fixing sleeve drives the grid frame to move up and down, and the grid frame turns the PVC pipe material at the bottom end of the material box upward, so that the PVC pipe material is continuously turned and mixed together, thereby achieving the effect of turning and mixing the PVC pipe material inside the material box and making the material mixing more fully.
