Side chain device

Abstract

The invention relates to a side chain device. The device comprises a driving chain wheel installed on a rack, a driving system driving the driving chain wheel to rotate and guide rails, wherein the guide rails comprise the arc guide rail and the linear guide rails, the two linear guide rails are unfolded towards the same side of the driving chain wheel from two tangent points of the driving chainwheel correspondingly, the arc guide rail is connected with the two linear guide rails through connecting plates, a chain is arranged in the guide rails, surrounds the driving chain wheel and circularly rotates among wheel teeth of the driving chain wheel and in the guide rails along with rotation of the driving chain wheel, and side dies are arranged on one sides of chain links of the chain and located on the same plane as the driving chain wheel so as to be used for achieving the function of the side chain device on a polyurethane colored steel sandwich plate continuous production line. According to the device, the arc guide rail is used for replacing a driven chain wheel to be directly connected with the lengthened linear guide rails, the free space between the guide rails and the chainwheel is eliminated, abrasion of the chain is reduced, the phenomena of bending, tooth skipping and the like occurring in the running process of the chain are avoided, and the forming quality of thepolyurethane colored steel sandwich plate is guaranteed.

Description

technical field [0001] The invention relates to a side chain device, in particular to a continuous production process of polyurethane color steel sandwich panels, which is used to prevent sprayed polyurethane liquid from flowing out of polyurethane color steel sandwich panels and to be used for polyurethane color steel sandwich panels. The invention relates to a side chain device for sealing edges, simultaneously overcoming the lateral force generated by polyurethane material liquid during foaming and curing, and guiding the movement of polyurethane color steel sandwich panels in a double track laminator, belonging to the technical field of sandwich panel production equipment. Background technique [0002] Color steel sandwich panel is a common material in modern buildings. It is made of upper and lower layers of metal panels and a middle layer of polymer heat insulation core. It has the characteristics of flame retardant and sound insulation, easy installation, light weight,...

Problems solved by technology

[0012] Since each group of chain links of the chain 4 is connected by a pin shaft 44, when the side chain device is in operation, friction will be generated between the pin shaft 44 and the sleeve 43, and this friction cannot be completely eliminated no matter whether there is lubrication or not. , so, after the chain 4 is used for a period of time, the distance between two adjacent chain links will become larger, so that the overall elongation of the chain 4 occurs, that is, the chain 4 is worn out.

[0013] When the chain 4 is worn out, the chain 4 is prone to tooth skipping during transmission, thereby affecting the stability of the side chain device operation; due to the unstable operation of the chain 4, the operation of the side mold 8 will be unstable; Die 8 is used to ensure that the polyurethane color steel sandwich panel is continuous, to prevent the sprayed polyurethane material liquid from flowing out of the polyurethane color steel sandwich panel, to seal the edge of the polyurethane color steel sandwich panel, and to overcome the foaming of the polyurethane material liquid The lateral force generated during the curing process guides the polyurethane color steel sandwich panel to move in the double track laminator. Therefore, once the side mold 8 is not running stably, it will affect the function of the side mold 8, and the polyurethane color steel sandwich panel cannot be guaranteed. The straightness and flatness of the edge line when the steel sandwich panel is solidified and formed, thus affecting the production of polyurethane color steel sandwich panels and the quality of polyurethane color steel sandwich panels

[0014] In addition, in the existing side chain device, the guide rail 5 used to guide the operation of the chain 4 is arranged between the driving sprocket 2 and the driven sprocket 3, between the guide rail 5 and the driving sprocket 2 and between the guide rail 5 and the driven sprocket 3 There is a section of free space between them, once the overall elongation phenomenon occurs in the chain 4, it will cause the chain 4 to twist and turn on the free space section, and the chain 4 will twist and turn, which will cause the side mold 8 fixed on the outside of the chain 4 to also bend. There are twists and turns, and the side mold 8 does not travel according to the preset trajectory. Once the side mold 8 does not follow the preset trajectory, the role of the side mold 8 cannot be exerted. The polyurethane material in the polyurethane color steel sandwich panel during curing and molding The liquid will overflow, which will affect the quality of polyurethane continuous color steel sandwich panel
