Rolling device used for HDPE plate production line

Abstract

The invention discloses a rolling device used for a HDPE plate production line. The rolling device comprises a rack, a driving mechanism, a jacking mechanism and a rolling assembly. One opposite sideof the rack is provided with a bearing seat, and a shaft support is installed on the other opposite side of the rack. A transmission shaft is rotationally arranged on the bearing seat, a guiding shaftis movably arranged on the shaft support in the transverse direction, and the guiding shaft is coaxially rotationally provided with a jacking head. The driving mechanism is installed on the rack andis in transmission connection with the transmission shaft. The jacking mechanism is installed on the rack and is in transmission connection with the guiding shaft. The rolling assembly is detachably arranged between the transmission shaft and the jacking head and comprises a center shaft, a pair of sliding sleeves arranged on the center shaft in a sliding manner, and multiple expansion plates arranged on the peripheral side of the center shaft in the circumferential direction. The pair of sliding sleeves are located at the two end portions of the center shaft correspondingly, the expansion plates are connected with the pair of sliding sleeves through multiple hinges, and the expansion plates are connected with the center shaft through multiple hinges. One sliding sleeve is connected with the transmission shaft, and the other sliding sleeve is connected with the jacking head.

Description

technical field [0001] The invention relates to the technical field of sheet and plate winding, in particular to a winding device used in an HDPE sheet material production line. Background technique [0002] High-density polyethylene (HDPE) is a white powder or granular product. It is a thermoplastic polyolefin produced by the copolymerization of ethylene. It is an environmentally friendly material. It can be recycled and reused after heating to the melting point. High-density polyethylene film has a low heat distortion temperature under stress, and because of its excellent mechanical properties, physical properties and environmental protection properties, it has a wide range of applications. The production of HDPE sheet is a kind of sheet made by extrusion process. HDPE production line usually includes extrusion device, cooling device, cutting device, stacking device, winding device, and the winding device is usually a single small coil diameter center The winding structur...

Problems solved by technology

The production of HDPE sheet is a kind of sheet made by extrusion process. HDPE production line usually includes extrusion device, cooling device, cutting device, stacking device, winding device, and the winding device is usually a single small diameter center Rewinding structure, the center rewinding structure is only suitable for the rewinding of thin plates with a thickness below 3mm, and it is difficult to rewind HDPE plates with a larger thickness of 3-8mm. Therefore, traditional rewinding products are only suitable for rewinding thin plates. It has limitations; in addition, the traditional winding equipment usually uses the structure of the inflatable shaft and the paper tube to rewind, which is only suitable for the winding operation of the thin plate with a small roll diameter. When unloading the roll, it needs to be unloaded together with the paper tube. It is inconvenient to roll and change rolls, and cause waste of resources such as paper tubes
