Description

Technical Field

[0001] The utility model relates to the technical field of PVC pellet cutting devices, in particular to a medical PVC pellet cutting mechanism. Background Art

[0002] Polyvinyl chloride, or PVC, is a polymer formed by free radical polymerization of vinyl chloride monomer in the presence of initiators such as peroxides and azo compounds, or under the influence of light or heat. PVC was once the world's most produced general-purpose plastic and is widely used. Existing medical PVC pellets are typically cut by submerging the extruded strips in water to cool them. Then, an electric hydraulic lever drives a cutter to cut the pellets.

[0003] The above technology still has shortcomings. After the water-cooled PVC pellets are cut and collected, they contain water droplets, which cause the water droplets to aggregate. Over time, this can easily lead to bacterial growth, affecting the use of medical PVC pellets. To address this issue, we propose a medical PVC pellet cutting mechanism to facilitate drying of the water in the PVC pellets. Utility Model Content

The collecting box is welded to the bracket of the cold water tank through a group of the connecting rods, a hot air blower is installed on the box wall of the collecting box, an exhaust trough is opened on the box wall of the collecting box, the hot air blower is located on one side of the exhaust trough, a motor is installed on the box wall of the collecting box by bolts, and a stirring shaft is installed on the output end of the motor.

[0006] By adopting the above technical solution, when the cut PVC pellets are collected, a collecting mechanism is installed at the bracket of the cold water tank, and the collecting mechanism is composed of a connecting rod, a collecting box, a motor, a discharge hopper, a stirring shaft, a hot air blower and an exhaust trough. The other end of the cutting plate is located at the top of the collecting box. After the cut PVC pellets enter the collecting box, the motor is controlled by the controller so that the motor drives the stirring shaft, and the stirring shaft flips the PVC pellets in the collecting box. The hot air blower is then controlled by the controller so that the hot air blower blows out hot air, so that the hot air enters the collecting box through the exhaust trough, thereby drying the water droplets on the surface of the PVC pellets and avoiding the accumulation of water droplets to cause bacterial growth.

[0007] Specifically, it also includes a cutting mechanism, and the cutting mechanism is installed on the wall of the cold water tank.

[0008] By adopting the above technical solution, the PVC strips can be cut into PVC pellets by the cutting mechanism.

[0009] Specifically, the cutting mechanism is composed of a fixing frame, a cutting plate, a through hole, an electric hydraulic rod and a cutting knife combination. The fixing frame is installed on the box wall of the cold water tank by bolts, the electric hydraulic rod is installed on the top of the fixing frame by bolts, the cutting knife is installed on the output end of the electric hydraulic rod, and the cutting plate is installed on the wall of the fixing frame by bolts. The other end of the cutting plate is located at the top of the collection box, and several groups of symmetrical through holes are opened on the wall of the fixing frame.

[0010] By adopting the above technical solution, when cutting the PVC pellets, a cutting mechanism is installed on the wall of the cold water tank, and the cutting mechanism is composed of a fixing frame, a cutting plate, a through hole, an electric hydraulic rod and a cutting knife. After the water in the cold water tank cools the PVC strips, the PVC strips pass through the through hole, so that the PVC strips are located on the top of the cutting plate. The electric hydraulic rod is controlled by the controller so that the electric hydraulic rod pushes the cutting knife at its output end downward, so that the cutting knife cuts the cooled PVC strips.

[0011] Specifically, a group of symmetrical limiting rollers are rotatably connected to the inner wall of the cold water tank, and a conveying roller is rotatably connected to the inner wall of the cold water tank.

[0012] By adopting the above technical solution, the extruded PVC strip can be pressed down and limited by the limiting roller, and the extruded PVC strip is located on the top of the conveying roller for conveying.

[0013] Specifically, a controller for controlling the motor, the hot air blower and the electric hydraulic rod is installed on the wall of the cold water tank.

[0014] By adopting the above technical solution, the motor, the hot air blower and the electric hydraulic rod can be conveniently controlled through the controller.
