Description

Technical Field

[0001] This utility model relates to the field of roller production technology, and more specifically, to a PVC roller raw material mixing and feeding device. Background Technology

[0002] PVC rollers are cylindrical industrial rolling parts made primarily of polyvinyl chloride (PVC). They are a type of functional roller. However, in the production process of PVC rollers, the existing raw material handling process typically involves drying and cooling the raw materials in separate drying and cooling devices. Hot air is generated by a heating device to dry the raw materials, and after drying, the materials are transferred to a cooling device for cooling. During this transfer process, secondary contamination of the raw materials is easily caused, and the materials are also prone to re-adhere to external moisture, greatly weakening the initial drying effect and affecting the final quality of the PVC rollers. Therefore, we propose a PVC roller raw material mixing and feeding device to solve the above problems. Utility Model Content

However, during the transfer process, not only is secondary contamination of the raw materials easy to occur, but the raw materials are also easy to re-adhere to external moisture, which greatly weakens the initial drying effect and affects the final quality of the PVC roller.

[0024] like Figures 4 to 7As shown, in another embodiment of this utility model, the mixing mechanism 2 includes a temporary storage box 201, which is fixedly installed on the upper surface of the injection molding cylinder 1 near the end of the second motor 6. A drying chamber 202 is provided inside the temporary storage box 201 near the second motor 6, and a cooling chamber 203 is provided through the interior of the temporary storage box 201 away from the second motor 6. The lower end of the cooling chamber 203 is connected to the injection molding cylinder 1. A connecting groove 204 is provided at the upper interior of the temporary storage box 201, and the two ends of the connecting groove 204 are respectively connected to the drying chamber 202 and the cooling chamber 203. The drying chamber 202 is interconnected, with feed pipes 205 installed through the front and rear sides of the upper part of the chamber. A first motor 206 is installed at the lower part of the drying chamber 202, and a rotating shaft 207 is installed at the output end of the first motor 206. The rotating shaft 207 is movably installed inside the drying chamber 202. Several mixing plates 208 are installed on the outer side of the shaft 207 inside the drying chamber 202. A groove 209 is provided at the lower part of the injection molding cylinder 1, located at the lower end of the drying chamber 202, and the groove 209 overlaps vertically with the drying chamber 202. A plurality of first exhaust holes 211 are provided between the 09 and the drying chamber 202. Each first exhaust hole 211 has a filter screen installed inside. A first air guide pipe 210 is installed through one end of the interior of the groove 209. A rotating rod 212 is movably installed through the upper end of the interior of the cooling chamber 203. A plurality of mixing racks 214 are installed on the outer side of the rod 212 inside the cooling chamber 203. A diversion groove 215 is provided through the interior of the rotating rod 212 and the mixing racks 214. A plurality of second exhaust holes 216 are provided through both sides of the diversion groove 215 inside the mixing racks 214. An air suction pipe 213 is installed through the upper part of the inner cavity 203 and on the side away from the drying cavity 202.

A second air guide pipe 221 is installed through the upper part of the connecting box 220.

[0025] The user injects the raw material into the drying chamber 202 through the feed pipe 205. Then, the first motor 206 starts and drives the rotating shaft 207 to rotate, which drives the mixing plate 208 to stir the raw material. At the same time, hot air enters the groove 209 through the first air guide pipe 210 and is then blown into the drying chamber 202 through the first exhaust hole 211. The filter screen in the first exhaust hole 211 can prevent impurities from entering the drying chamber 202 and contaminating the raw material. Under the combined action of stirring by the mixing plate 208 and hot air, the raw material is fully heated and dried, and residual moisture is removed.

[0026] After drying, the raw materials become lighter due to the evaporation of moisture. Under the upward blowing of high-temperature air and the attraction of hot air and dry cold air by the suction pipe 213, they enter the cooling chamber 203 along the connecting groove 204, which reduces the chance of the raw materials coming into contact with external moisture during the transfer process and ensures the drying effect.

[0027] Then, after the raw material enters the cooling chamber 203, the suction pipe 213 continuously draws in hot air and dry cold air. The rotating rod 212 rotates under the drive of the chain 219. The chain 219 connects the first sprocket 217 and the second sprocket 218. The first sprocket 217 is installed on the rotating shaft 207, and the second sprocket 218 is installed on the rotating rod 212. The rotating rod 212 is indirectly driven to rotate by the first motor 206. The mixing frame 214 rotates accordingly to further stir the raw material. The dry cold air enters the diversion tank 215 through the second air guide pipe 221 and the connecting box 220, and is then discharged through the second exhaust hole 216. During this process, the raw material is efficiently cooled and cooled to meet the conditions required for melting.

[0028] The cooled raw material falls into the injection barrel 1. The second motor 6 drives the screw 5 to rotate, pushing the raw material towards the injection head 4. The heating coil 3 heats and melts the raw material in the injection barrel 1, giving it good fluidity. As the raw material continues to melt and is pushed towards one end of the injection head 4, the screw 5 and the second motor 6 will automatically move due to the accumulation of the raw material. When the raw material needs to be extruded, the cylinder 9 simply pushes the second motor 6 and the screw 5 through the push plate 10. The screw 5 then pushes the liquid raw material, allowing it to be extruded and injection molded through the injection head 4.

[0029] The working principle of this PVC roller raw material mixing and feeding device:

[0030] In use, the user first injects the raw material into the drying chamber 202 through the feed pipe 205. Then, the first motor 206 starts, driving the rotating shaft 207 to rotate, which in turn drives the mixing plate 208 to stir the raw material. At the same time, hot air enters the groove 209 through the first air guide pipe 210 and is then blown into the drying chamber 202 through the first exhaust hole 211. Under the combined action of the mixing plate 208 and the hot air, the raw material is fully heated and dried, removing residual moisture. The dried raw material becomes lighter due to the evaporation of moisture. The upward blowing of the high-temperature air and the attraction of hot and dry cold air by the suction pipe 213 further enhance the drying effect. Under the action of the material, it enters the interior of the cooling chamber 203 along the connecting groove 204. After the material enters the cooling chamber 203, the suction pipe 213 continuously draws in hot air and dry cold air. The rotating rod 212 rotates under the drive of the chain 219 to further stir the material. Then, the dry cold air enters the diversion groove 215 through the second air guide pipe 221 and the connecting box 220, and is discharged through the second exhaust hole 216. During this process, the material is efficiently cooled and cooled to meet the conditions required for melting. Finally, the cooled material falls into the injection cylinder 1. The second motor 6 drives the screw 5 to rotate, pushing the material towards the injection head 4. Heating coil 3 heats and melts the raw material inside injection cylinder 1, giving it good fluidity. As the raw material continues to melt and is pushed towards one end of injection head 4, screw 5 and second motor 6 will automatically move due to the accumulation of raw material. When the raw material needs to be extruded, cylinder 9 simply pushes second motor 6 and screw 5 through push plate 10. Screw 5 can then push the liquid raw material, allowing it to be extruded and injection molded through injection head 4.

[0031] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
