Extrusion equipment for production of door and window sealing strips

Abstract

The invention discloses extrusion equipment for production of door and window sealing strips. The extrusion equipment comprises a supporting plate, a feeding wheel is arranged on the left side of the supporting plate, a sliding rail is arranged on the right side of the feeding wheel, a tension wheel is arranged in the sliding rail, an extrusion wheel is arranged on the right side of the tension wheel, a heating shell is arranged on the right side of the extrusion wheel, and an extrusion mold is connected with the right side of the heating shell. According to the extrusion equipment for the production of the door and window sealing strips, through the feeding wheel, a raw rubber strip roll serving as a raw material can be loaded on the equipment, the conveying tension of the raw rubber strip is controlled through the tension wheel, continuous conveying of the raw rubber strip is achieved through the extrusion wheel, and therefore a heating cavity in the heating shell melts and extrudes the rubber strip; the raw rubber strip is directly adopted as the raw material, the phenomenon that air is mixed among rubber particles is avoided, and the quality of the produced sealing strip is guaranteed; and meanwhile, feeding is carried out through the extrusion wheel, the feeding speed is controlled to be constant through the tension wheel, and it is guaranteed that the quality of the sealing strip is not affected by feeding.

Description

technical field [0001] The invention relates to the field of sealing strip production, in particular to extrusion equipment for the production of door and window sealing strips. Background technique [0002] The sealing strip is a kind of rubber strip that is installed at the joints of doors and windows to seal. Through the setting of the "concave" shape of the sealing strip, it can effectively prevent water and air leakage from the part used. It is generally extruded The extruder is extruded and shaped according to the corresponding shape, so as to facilitate subsequent installation and ensure the sealing effect after the sealing strip is installed. The sealing strip extruder generally heats the rubber material, and then passes the heated and melted rubber through the extrusion die, so that It is shaped to obtain the shape of the sealant strip that needs to be produced, but the extrusion equipment currently on the market still has the following problems: [0003] 1. Most o...

Problems solved by technology

[0007] The object of the present invention is to provide a kind of extrusion equipment for the production of door and window sealing strips, to solve the problem that most of the existing sealing strip extruders proposed by the above-mentioned background technology adopt a spiral conveying structure, and when extruding and conveying, the conveying capacity Small size leads to low extrusion efficiency during production, and the screw conveying structure generally uses granular rubber raw materials. During the material conveying process, due to the gaps between the particles, air bubbles will be generated inside during conveying and extrusion molding. As a result, the quality of the produced sealing rubber strips is poor and easy to be damaged. For extruders that directly use rubber strips as raw materials, they are usually fed manually to send the rubber strips into the heating chamber. Manual feeding cannot guarantee the feeding speed, resulting in The finished product produced is not uniform. After the rubber strip is extruded by the sealing strip extruder, it needs to be cut off at the outlet in real time to prevent the finished rubber strip from clogging the exit, causing the rubber strip to be blocked at the exit after being extruded. , resulting in the deformation of the rubber strip, and most of the existing sealing strip extruders are manually inspected and cut, which leads to errors in each cutting, and manual cutting is often unable to keep up with the production rate of the machine, resulting in accumulation. As a result, the rubber strip is deformed. When the existing sealing strip extrusion equipment is in production, it mainly ensures the production of the sealing rubber strip through the mold provided at the extrusion port. In order to be able to produce different shapes of sealing rubber strips, the extrusion die needs Replacement, although the current sealing strip extruder is more convenient in mold replacement, but the material receiving device is fixed or difficult to adjust, resulting in the accumulation of products produced after replacing the sealing strip extrusion mold, resulting in The problem of the deformation of the rubber strip at the extrusion port
