Abstract

The invention discloses unsymmetrical compound machine heads of a passageway of a wide rubber sheet extruder, comprising a plurality of extruding machine heads arranged in parallel, wherein a crossing part of passageway chambers between the adjacent extruding machine heads is connected by a mixer or a material stream divider; the passageway chamber of the outermost side extruding machine head uses an unsymmetrical structure; and passageway chambers of the middle extruding machine heads use a symmetrical structure. The unsymmetrical structure of the passageway chamber is that the top part of the passageway chamber deviates from an extruding central line to the outside; and the angle between an opening direction of the passageway in the passageway chamber and the extruding central line is greater than the angle between the opening direction of the outside passageway and the extruding central line. The extruding machine head in the invention uses the unsymmetrical passageway structure so that two or a plurality of passageways are extruded in parallel; the width scale of the rubber sheet is skillfully enlarged; the maximal yield is improved; the manufacturing cost and the processing difficulty are decreased; and the compound strength and the rubber sheet quality are guaranteed under enough pressure and space.

Description

(1) Technical field:

[0001] The invention relates to wide-width film production equipment, in particular to a wide-width film extruder flow channel asymmetric composite head. (two) background technology:

[0002] The wide-width film extruder is the main equipment for producing wide-width film by extrusion calendering. The production of wide-width film by extrusion calendering can greatly improve the product quality of the film, overcome the shortcomings of traditional production processes, and greatly improve the quality of the film. production efficiency.

[0003] The wide-format film extruder is mainly composed of a pin cold-feed extruder and a wide-format film head. The extruder determines the maximum capacity of the equipment, and the machine head determines the product specifications that the equipment can produce. At present, the maximum production capacity of the largest pin cold-feed extruder in China is about 4000kg / h, and the conventional width specification of wi...

Embodiment Construction

[0025] The wide-width film extruder flow channel asymmetrical compound head of the present invention is composed of two extruder heads 1 of different types or the same type arranged side by side, such as figure 1 , figure 2 , image 3 , Figure 4 As shown, the two extruder heads 1 are horizontally side by side, and the outlets of the two extruder heads 1 are in a straight line.

[0026] 1. The two extruder heads 1 are connected by the set mixer 3 for double extrusion production:

[0027] Such as image 3 As shown, the flow mixer 3 is connected at the junction of the two extruder heads 1 adjacent to the runner cavity 2. When the two extruder heads 1 extrude the rubber material at the same time, the film with the widest specification can be produced. For a slightly smaller film, the runner inserting blocks 5 can be respectively arranged outside the runner chamber 2 of the two extruder heads 1, and the minimum distance between the two runner inserting blocks 5 is the width o...
