Description

An extruder for processing plastic sheets Technical Field

[0001] This utility model belongs to the field of plastic sheet processing technology, specifically relating to an extruder for processing plastic sheets. Background Technology

[0002] Plastic sheets refer to materials used in the production of disposable plastic cups, plates, bowls, dishes, boxes, and other thermoformed products. They are widely used in packaging for food, vegetables, fruits, beverages, dairy products, and industrial parts. Due to size limitations during production, plastic sheets require continuous cutting after molding to achieve standard dimensions. Existing technologies use a fixed thickness for extruding plastic sheets, making it unsuitable for sheets requiring various thicknesses. Therefore, there is an urgent need to design an extruder for processing plastic sheets to address these issues. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model discloses an extruder for processing plastic sheets.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] An extruder for processing plastic sheets includes a base, a processing and stirring mechanism disposed above the base, and a movable extrusion mechanism disposed on one side of the processing and stirring mechanism.

[0006] The mobile extrusion mechanism includes an extrusion box fixedly mounted on the processing and mixing mechanism. A push plate is longitudinally movable inside the extrusion box, and an electric telescopic rod is fixedly installed on the push plate. A second guide pipe is fixedly installed on one side of the extrusion box. A lead screw is horizontally parallel below the second guide pipe. A power motor is installed at one end of the lead screw. A moving table is movably mounted on the outer surface of the lead screw. An electric lifting rod is fixedly installed above the moving table. An extrusion roller is fixedly mounted at the power end of the electric lifting rod. A second motor is installed on the extrusion roller. A scraper is installed on one side of the extrusion roller.

[0007] Preferably, the processing and mixing mechanism includes a frame fixedly mounted above the base, a box fixedly mounted above the frame, a cylinder fixedly mounted inside the box, a heating component mounted on the outer surface of the cylinder, a drive motor mounted above the cylinder, a first rotating rod mounted on the power end of the drive motor, a mixing component fixedly mounted on the outer surface of the first rotating rod, a material blocking component mounted below the cylinder, a horizontal cylinder fixedly mounted below the cylinder, a screw conveyor assembly horizontally mounted inside the horizontal cylinder, and a first guide pipe mounted at the lower end of the cylinder.

[0008] Preferably, a receiving box is fixedly installed above the base and below the extrusion roller.

[0009] Preferably, one end of the lead screw has a forward thread on its outer surface, and the other end has a reverse thread on its outer surface.

[0010] Preferably, the heating assembly includes a heating tube disposed on the outer surface of the cylinder, and a heater is disposed on the outer surface of the heating tube.

[0011] Preferably, the auger assembly includes a second rotating rod arranged laterally inside the cross cylinder, a first motor being provided at one end of the second rotating rod, and auger blades being provided on the outer surface of the second rotating rod.

[0012] The beneficial effects are:

[0013] This utility model discloses an extruder for processing plastic sheets. A movable extrusion mechanism draws plastic raw material, after passing through a processing mixing mechanism, into an extrusion chamber. An electric telescopic rod is activated to move the push plate, pushing the plastic raw material in the extrusion chamber to the left, where it flows out through a second guide pipe. A power motor drives a lead screw to rotate, causing the moving table, electric lifting rod, and extrusion rollers to move relative to or towards each other. The thickness of the plastic sheet is controlled by moving the extrusion rollers according to the desired thickness. Once the extrusion rollers have moved to a designated position, a second motor is activated to rotate them, processing the plastic raw material into sheets. A scraper on one side of the extrusion rollers removes excess material from its outer surface, ensuring effective plastic sheet processing. This machine adapts to various sheet thicknesses, improves processing efficiency, and is convenient and practical. Attached Figure Description

[0025] In this embodiment: the mobile extrusion mechanism 3 includes an extrusion box 301 fixedly mounted on the processing and mixing mechanism 2. A push plate 302 is longitudinally movably arranged inside the extrusion box 301. An electric telescopic rod 3021 is fixedly installed on the push plate 302. A second guide pipe 303 is fixedly installed on one side of the extrusion box 301. A lead screw 304 is arranged horizontally and parallel below the second guide pipe 303. A power motor 305 is installed at one end of the lead screw 304. A moving platform 306 is movably arranged on the outer surface of the lead screw 304. An electric lifting rod 307 is fixedly installed above the moving platform 306. An extrusion roller 308 is fixedly installed at the power end of the electric lifting rod 307. A second motor 309 is installed on the extrusion roller 308. A scraper 310 is arranged on one side of the extrusion roller 308. A receiving box 311 is fixedly installed above the base 1 and installed below the extrusion roller 308. A positive spiral thread is provided on the outer surface of one end of the lead screw 304, and a negative spiral thread is provided on the outer surface of the other end of the lead screw 304.

[0026] Working Principle: In operation, the heating resistance wire in the heating tube 204 is first heated by the heater 205 to heat the cylinder 203. The drive motor 206 on the cylinder 203 is then started to rotate the first rotating rod 207, the stirring blade 208, and the extrusion blade 209. After heating for a certain period of time, the plastic sheet material is fed into the cylinder 203 through the feeding pipe. The rotating first rotating rod 207, the stirring blade 208, and the extrusion blade 209 heat and stir the plastic sheet material. After stirring for a certain period of time, the material blocking assembly 210 is opened to allow the heated and stirred plastic sheet material to fall into the horizontal cylinder 211. The first motor 213 is then started to rotate the second rotating rod 212 and the auger blade 2121, which in turn transport the heated and stirred plastic sheet material through the first guide pipe. 2111 flows into the extrusion box 301. When a certain amount of the heated and stirred plastic sheet material flows into the extrusion box 301, the electric telescopic rod 3021 is activated to drive the push plate 302 to push the plastic sheet material to the left and out through the second guide pipe 303. The operator can start the power motor 305 to drive the lead screw 304 to rotate according to the extrusion size of the plastic sheet, and drive the moving table 306, electric lifting rod 307, and extrusion roller 308 to move relative to or towards each other, and adjust the movement of the extrusion roller 308. At the same time, the second motor 309 is activated to adjust the rotation of the extrusion roller 308 to extrude the plastic sheet and drop it into the receiving box 311. The excess material on the outer surface of the extrusion roller 308 is scraped off by the scraper 310 to ensure that the outer surface of the extrusion roller 308 is clean and can better extrude the required plastic sheet.
