Description

Technical Field

[0001] The utility model relates to the technical field related to calenders, in particular to a continuous calender for ultra-thin flexible polycarbonate substrates. Background Art

[0002] Ultra-thin flexible polycarbonate substrate is a substrate made of polycarbonate material with ultra-thin thickness and good flexibility. It has broad application prospects in many fields such as electronic products, automobile manufacturing, construction and medical fields. The process of producing ultra-thin flexible polycarbonate substrate is a comprehensive process involving multiple links such as raw material preparation, mixing, melting, calendering, cooling and curing, and post-processing. Among them, the calendering step requires the use of a continuous calender. The continuous calender applies pressure and shear force to the material entering the roller gap through the interaction of a series of rollers, causing the material to be squeezed and stretched, and finally forming a sheet product with a specific thickness and width.

[0003] During use, the existing ultra-thin flexible polycarbonate substrate continuous calender needs to manually adjust the position of the baffle on the roller to control the outward extension of the material under the pressure of the roller. In order to prevent safety hazards in the production process, the machine needs to be stopped, which is not practical. Therefore, it is necessary to propose an ultra-thin flexible polycarbonate substrate continuous calender. Utility Model Content

[0004] The purpose of the utility model is to provide a continuous calender for an ultra-thin flexible polycarbonate substrate to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: a continuous calender for an ultra-thin flexible polycarbonate substrate, comprising a calender body, a roller mounted on the inner side of the calender body, an adjustment mechanism disposed above the calender body, and a fixing mechanism disposed below the adjustment mechanism;

[0006] The adjustment mechanism includes a fixed frame, a hydraulic cylinder, a hydraulic rod, a limit rod, a limit ring and a connecting plate. The fixed frame is fixed to the upper surface of the calender body. A hydraulic cylinder is installed on the lower side of the fixed frame. A hydraulic rod is installed on one end of the hydraulic cylinder. The limit rod passes through the upper side of the fixed frame. A limit ring is sleeved on the outer side of the limit rod. A connecting plate is fixed below the limit ring.

[0007] Preferably, the connecting plate forms a sliding structure through a limiting ring and a limiting rod, and the inner cross-sectional shape of the limiting ring is consistent with the cross-sectional shape of the limiting rod.

[0008] Preferably, the connecting plate performs horizontal reciprocating motion on the fixing frame through a hydraulic rod, and the connecting plate and the fixing frame are distributed in parallel.

[0009] Preferably, the fixing mechanism includes a sleeve, a block, a baffle and a bolt. The sleeve is fixed to one side of the connecting plate. The inner side of the sleeve is provided with a block. A baffle is fixed to one side of the block. A bolt passes through one side surface of the baffle.

[0010] Preferably, the baffle is connected to the ferrule through a clamping block, and the inner cross-sectional shape of the ferrule is consistent with the outer cross-sectional shape of the clamping block.

[0011] Preferably, the baffle is threadably connected to the ferrule via bolts, and the bolts are symmetrically arranged about the center axis of the baffle.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. This ultra-thin flexible polycarbonate substrate continuous calender, through the arrangement of the calender body, rollers, and adjustment mechanism, allows the operator to conveniently adjust the position of the baffle on the roller by turning on the hydraulic cylinder switch during use, without having to manually move the baffle. This controls the outward extension of the material under the pressure of the roller, allowing the material to maintain a certain shape and size during the calendering process. The position of the adjustable baffle can be adjusted without stopping the device, reducing production interruption time caused by downtime and improving the practicality of the device.

[0014] 2. This ultra-thin flexible polycarbonate substrate continuous calender, through the arrangement of rollers and fixing mechanisms, can conveniently remove the baffle from the clamping sleeve by removing the bolts during use of the device, thereby facilitating replacement or maintenance of the baffle. The clamping sleeve engages the clamping block to prevent the baffle connected to the clamping block from displacement, so that the device can more stably fix the baffle, thereby improving the practicality of the device.
