A plastic film extrusion and calendering production line

Abstract

This utility model discloses a plastic film extrusion and calendering production line, which includes an extruder and a calender. A feed hopper is installed on the top of the extruder, and a steel frame fixedly installed on the ground is located on the outer side of the extruder. A storage hopper is fixedly installed on the inner wall of the steel frame, and a perforated plate is slidably connected to the bottom of the storage hopper. Side plates are welded to the surface of the steel frame, and cylinders are bolted to the surface of the side plates. A material cylinder is integrally formed at the bottom of the perforated plate, and a support plate is provided at the bottom of the material cylinder. This utility model uses the perforated plate to move the material cylinder. At this time, the perforated plate seals the bottom of the storage hopper, and the material cylinder causes the support plate to detach from the top of the I-beam. This allows the masterbatch in the material cylinder to be pressed against the support plate under gravity, causing it to flip and exit into the feed hopper. This achieves the purpose of quantitative feeding of the extruder feed hopper through the movement of the metering cylinder, thereby improving the smoothness of extruder operation and discharge.

Description

Technical Field

[0001] This utility model belongs to the field of plastic film processing technology, and in particular relates to a plastic film extrusion and calendering production line. Background Technology

[0002] Plastic film extrusion calendering is an important plastics processing technology, widely used in the production of various plastic films and sheets. This technology combines extrusion and calendering processes, enabling the production of plastic films with specific thicknesses and surface qualities. Plastic film extrusion calendering technology occupies an important position in modern plastics processing, and its wide range of applications and efficient production methods make it the preferred process for many industries.

[0003] Some plastic film extrusion calendering production lines use twin-screw extruders, whose forced screw pushing characteristics require strict control of the feeding amount. Some twin-screw extruders feed the masterbatch to be processed directly into the extruder feed hopper. This may cause the screw to overload and stop due to excessive feeding, or cause output fluctuations due to insufficient feeding. Therefore, there is a need for a plastic film extrusion calendering production line that can quantitatively feed the extruder feed hopper by moving the metering cylinder, thereby improving the smoothness of extruder operation and output. Utility Model Content

[0004] The purpose of this invention is to provide a plastic film extrusion and calendering production line that uses the movement of a metering cylinder to quantitatively feed material into the extruder feed hopper, thereby improving the smoothness of extruder operation and discharge, and solving the technical problems mentioned in the background art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A plastic film extrusion and calendering production line includes an extruder and a calender: a feed hopper is installed on the top of the extruder, a steel frame is fixedly installed on the ground on the outside of the extruder, a storage hopper is fixedly installed on the inner wall of the steel frame, a perforated plate is slidably connected to the bottom of the storage hopper, a side plate is welded to the surface of the steel frame, a cylinder is fixedly connected to the surface of the side plate by bolts, a material cylinder is integrally formed at the bottom of the perforated plate, a support plate is provided at the bottom of the material cylinder, an I-beam is welded to the surface of the steel frame, and ear block one and ear block two are integrally formed on the surfaces of the material cylinder and the support plate, respectively, and a rotating shaft is provided on the outside of the material cylinder.

[0006] Preferably, the output end of the cylinder passes through the side plate and is fixedly connected to the orifice plate.

[0007] Preferably, a slide rail is fixedly connected to the surface of the side plate by bolts, and a slider is slidably connected to the surface of the slide rail, with the slider being fixedly connected to the perforated plate.

[0008] Preferably, the second ear block is fixedly connected to the rotating shaft, and the rotating shaft is rotatably connected to the first ear block.

[0009] Preferably, the bottom of the tray is in contact with the top of the I-beam.

[0010] The beneficial effects of this utility model are: 1. This utility model uses a perforated plate to drive the material cylinder to move. At this time, the perforated plate blocks the bottom of the storage hopper, and the material cylinder drives the pallet to detach from the top of the I-beam plate. This causes the masterbatch in the material cylinder to press the pallet to flip and fall out into the feed hopper under the action of gravity. This achieves the purpose of quantitative feeding of the extruder feed hopper by moving the quantitative cylinder, thereby improving the smoothness of extruder operation and discharge. 2. This utility model uses the combined use of slide rail and slider to limit the movement of the perforated plate, thereby preventing the perforated plate from shaking during movement and improving the stability of the perforated plate during movement.

A slider 10 is slidably connected to the surface of the rail 9. The slider 10 is fixedly connected to the perforated plate 6. Through the cooperation of the rail 9 and the slider 10, the movement of the perforated plate 6 is limited, which avoids the shaking of the perforated plate 6 when it moves, thereby improving the stability of the perforated plate 6 when it moves. A material cylinder 11 is integrally formed at the bottom of the perforated plate 6. A support plate 12 is provided at the bottom of the material cylinder 11. An I-beam plate 13 is welded to the surface of the steel frame 4.

A rotating shaft 16 is provided on the outside of the material cylinder 11. Example 2

[0015] Figure 1-3 This invention illustrates a plastic film extrusion and calendering production line according to an embodiment of the present invention, comprising an extruder 1 and a calender 2: a feed hopper 3 is installed on the top of the extruder 1, a steel frame 4 is fixedly installed on the ground on the outside of the extruder 1, a storage hopper 5 is fixedly installed on the inner wall of the steel frame 4, a perforated plate 6 is slidably connected to the bottom of the storage hopper 5, a side plate 7 is welded to the surface of the steel frame 4, a cylinder 8 is fixedly connected to the surface of the side plate 7 by bolts, a material cylinder 11 is integrally formed at the bottom of the perforated plate 6, a support plate 12 is provided at the bottom of the material cylinder 11, an I-beam 13 is welded to the surface of the steel frame 4, ear blocks 14 and 15 are integrally formed on the surfaces of the material cylinder 11 and the support plate 12, respectively, a rotating shaft 16 is provided on the outside of the material cylinder 11, the ear block 15 is fixedly connected to the rotating shaft 16, the rotating shaft 16 is rotatably connected to the ear block 14, and the bottom of the support plate 12 is in contact with the top of the I-beam 13.

[0016] Working principle: When using this utility model, the user places the masterbatch into the storage hopper 5, allowing the granules in the storage hopper 5 to enter the material cylinder 11. At this time, the cylinder 8 is activated, which drives the material cylinder 11 to move through the perforated plate 6, causing the perforated plate 6 to seal the bottom of the storage hopper 5. The material cylinder 11 also causes the support plate 12 to detach from the top of the I-beam plate 13. With the cooperation of the lug 14, lug 2 15 and the rotating shaft 16, the masterbatch in the material cylinder 11 is pressed by gravity, causing the support plate 12 to flip and fall out into the feed hopper 3. Subsequently, the plastic is extruded and calendered by the cooperation of the extruder 1 and the calender 2. This realizes the quantitative feeding of the extruder feed hopper by moving the quantitative cylinder, thereby improving the smoothness of the extruder operation and discharge.

[0017] In summary, this plastic film extrusion and calendering production line moves the barrel 11 via the perforated plate 6. At this time, the perforated plate 6 seals the bottom of the storage hopper 5, and the barrel 11 drives the pallet 12 to detach from the top of the I-beam 13. This causes the masterbatch in the barrel 11 to be pressed by gravity, causing the pallet 12 to flip and fall out into the feed hopper 3. This achieves the purpose of quantitative feeding of the extruder feed hopper by moving the metering cylinder, thereby improving the smoothness of extruder operation and discharge.
