Description

Technical Field

[0001] The utility model relates to the technical field of rubber and plastic machinery, in particular to an EPDM rubber strip extruder. Background Art

[0002] EPDM rubber strips, whose full name is EPDM rubber strips, are terpolymer rubber products made by copolymerization of ethylene, propylene and a small amount of non-conjugated dienes. This rubber has excellent aging resistance due to its unique molecular structure and chemical properties, including ozone resistance, heat resistance, weather resistance, etc., and is therefore widely used in many fields.

[0003] In the process of implementing the present invention, the inventors discovered that the prior art has at least the following problems:

[0004] During the production process of EPDM rubber strips, the EPDM rubber raw materials are first mixed evenly in a certain proportion and preheated to an appropriate temperature. The preheated raw materials are fed into the screw part of the extruder. Through the rotation and shearing action of the screw, the raw materials are gradually plasticized and pushed forward in the barrel. Under the push of the screw, the raw materials are extruded into the required shape and size through the die head. The extruded rubber strips are formed by cooling. The current cooling equipment is mostly long-distance air-cooled pipes or water tanks, which occupy a large area in actual applications.

[0005] Therefore, the above technical problems need to be solved. Utility Model Content

[0006] In order to overcome the deficiencies of the prior art, the utility model proposes an EPDM rubber strip extruder, which solves the problem that the cooling device of the current EPDM rubber strip extrusion equipment occupies a large area.

[0007] In order to solve the above technical problems, the basic technical solutions proposed by the present invention are as follows:

[0008] The EPDM rubber strip extruder comprises a discharging mechanism and a cooling mechanism mounted on the output end of the discharging mechanism through a machine base.

[0009] The cooling mechanism includes a stand and support plates and a water tank that are distributed on the front of the stand in upper and lower directions. The support plates are distributed along a horizontal plane and two fans are fixedly installed on the top of the support plates.

[0010] It also includes a feed roller group installed on the front of the stand for conveying EPDM rubber strips. The feed roller group consists of several first rollers and several second rollers in the same horizontal plane. Several second rollers and several first rollers are staggered in the upper and lower directions.

[0011] Preferably, the plurality of first rollers are all rotatably mounted in the water tank along the width direction of the water tank. The plurality of first rollers are positioned and rotatably mounted in the water tank, and can cooperate with the plurality of second rollers to form a continuous curved conveying of the output EPDM rubber strips.

[0012] Preferably, the front of the water tank is provided with a water inlet pipe and a drain pipe, which are respectively installed diagonally. The water inlet pipe is arranged at the top of the outer wall of the water tank near the discharge mechanism. The provision of the water inlet pipe and the drain pipe can achieve circulating water cooling, and the placement of the water inlet pipe near the output end of the discharge mechanism can further improve the cooling efficiency.

[0013] Preferably, it also includes a cylinder vertically mounted on the back of the stand and a mounting frame arranged in front of the stand for rotatable assembly of several second rollers. The output end of the cylinder is fixedly mounted with a connecting rod for mounting the mounting frame. The stand is provided with limiting holes distributed in the vertical direction for the connecting rod to pass through. The cylinder, the connecting rod and the mounting frame form a lifting mechanism for the several second rollers. By means of the extension and retraction of the output end of the cylinder, the lifting and lowering of the several second rollers can be achieved, thereby adjusting the feeding layout of the EPDM rubber strips to further optimize the cooling effect. It should be noted that if a lifting mechanism is configured, such as Figure 2 As shown, the initial layout of the first roller and the second roller is that the horizontal plane of the first roller is higher than the horizontal plane of the second roller, so as to facilitate the insertion and guidance of the EPDM rubber strip. If the lifting mechanism is not configured, the layout of the first roller and the second roller is that the horizontal plane of the second roller is higher than the horizontal plane of the first roller, and multiple second rollers are mounted above the water tank.

[0014] Preferably, both ends of the plurality of first rollers and the plurality of second rollers are provided with a conical flared structure. The conical flared structure at the ends of the first roller and the second roller forms a limiting mechanism, which can prevent the EPDM rubber strip from falling off during transportation and ensure stable transportation.

[0015] The beneficial effects of the utility model are:

[0016] The technical solution of the present invention is to form a mixed cooling of air cooling and water cooling for the output EPDM rubber strips by respectively arranging fans and water tanks at the top and bottom of the stand. In addition, the feed roller group composed of a plurality of second rollers and a plurality of first rollers staggered upper and lower is combined to effectively reduce the floor space occupied by the cooling device. At the same time, the cooling time is extended to a certain extent, ensuring the cooling effect. BRIEF DESCRIPTION OF THE DRAWINGS
