Abstract
The present invention discloses a high elastic reticular plastic soft pad, a continuous production method and equipment. The product comprises a plurality of plastic wires, which are mutually bonded. The bonding points are orderly arranged with intervals on a plane and a fa question mark ade. Every bonding point bonds two adjacent plastic wires. The key point of the production method is that molten plastics are formed into a plastic wire soft billet in a plastic wire pad forming die to move downwards. While moving downwards, the plastic wire billet alternatively swings positively and reversely along an arc track of the plane and bonds with an adjacent plastic wire soft billet in segment in a vertical direction. And a plastic wire pad material billet with orderly arranged bonding points with intervals on the plane and the facade is formed. The equipment is mainly a wire pad forming die, which is equipped with an upper and a lower fixing templates. A material channel is arranged between the upper template and the lower template. A plurality of rotary die cores vertically penetrates the upper and the lower fixing templates (connected in a way of sliding) and is arranged on a same plane in rows and columns. The upper ends of the rotary die cores are connected with a rotary driving device in a way of fixing. The lower ends of the rotary die cores are evenly equipped with a plurality of vertical grooves. The lower ends of the vertical grooves on two adjacent rotary die cores are communicated.
Description
Technical field:
The present invention relates to a kind of elastomer cushion and production method, special equipment, especially a kind of good permeability, cost is low, intensity is high, the simple high elasticity netted plastic cushion of production technology, continuous producing method and equipment.
Background technology:
High elasticity netted plastic cushion is by mutual bonding the forming of many plastics silks, because of it has higher elasticity and certain gas permeability, so often be applied to cushion, mattress etc.At present, the production method of high elasticity netted plastic cushion is that plastic extruder is extruded the plastics of melting downwards by fixing porous spinneret, form plastics silk soft paste, plastics silk soft paste is piled up in shaped device, mutual bonding formation plastics silk blank, gets final product through devices such as supercooling, typing, side cut, severing and rollings again.Because plastics silk soft paste is accumulation, bonding under free state, the coincidence of plastics silks is bonding and adhesive spots is unordered often to cause many, the quality of product unit volume is increased the weight of, cause waste of material, ventilative uniformity, plastic strip to product have also all produced harmful effect in conjunction with fastness and bulk strength, for this reason, often need in the production process through spray-bonding craft to improve performance such as intensity.Spray glue not only makes the unit volume quality of product further increase the weight of, and in the flash baking process, can produce the volatile matter of a lot of harmful human bodies, environment, and even so, bulk strength still can not satisfy the needs of use.
Summary of the invention:
The present invention is in order to solve existing in prior technology the problems referred to above, provides a kind of good permeability, cost is low, intensity is high, the simple high elasticity netted plastic cushion of production technology, continuous producing method and equipment.
Technical solution of the present invention is: a kind of high elasticity netted plastic cushion, and by many plastics silks 1 mutual bonding forming, the adhesive spots 2 of described plastics silk 1 is arranged on plane, facade at interval in order, and each adhesive spots 2 is bonded with two adjacent plastics silks 1.
A kind of continuous producing method of high elasticity netted plastic cushion is characterized in that having the following steps:
A. with in the melting plastics injected plastic silk pad mould;
B. the melting plastics form plastics silk soft paste and move down in plastics silk pad mould, when moving down, plastics silk soft paste, is formed on the plastics silk bedding and padding base of arranging adhesive spots on plane, the facade at interval in order along plane arc track positive and negative alternate swing and bonding with close plastics silk soft paste in the vertical direction compartment;
C. plastics silk bedding and padding base is through cooling, typing, side cut, severing.
A kind of continuous production equipment of high elasticity netted plastic cushion, plastic extruder 3, plastics silk pad mould 4, cooling and shaping device 5, draw-gear 6, trimming device 7, cutting device 8 are arranged, it is characterized in that: described plastics silk pad mould 3 is provided with upper and lower fixed form 9,10, horizontal material channel 11 is arranged between the fixed form 9,10 up and down, a plurality of rotation core rods 12 vertically run through upper and lower fixed form 9,10 and at grade in a row, become to show preface and arrange; Rotation core rod 12 slides with upper and lower fixed form 9,10 and joins, the upper end and the rotating driving device 13 of rotation core rod 12 are fixedly connected, the position that joins in 10 slips of rotation core rod 12 up and down fixed forms evenly is provided with a plurality of vertical grooves 14, and vertical groove 14 lower ends on the adjacent rotation core rod 12 communicate.
Described rotation core rod 12 lower end profiles are horn-like.
Described rotating driving device 13 is provided with drive motors 15, be connected to crank connecting rod apparatus 16 with drive motors 15, linear reciprocation bar 17 with crank connecting rod apparatus 16 joins is connected with swing arm 18 with linear reciprocation bar 17 bearing pins, and swing arm 18 is fixedly connected with the upper end of rotation core rod 12.
With the product that method of the present invention, equipment are produced, its plastics silk adhesive spots is to arrange in order at interval on plane, facade, and each adhesive spots only is bonded with two adjacent plastics silks.Because plastics silk soft paste is bonding in order in mould, so can solve plastic strip in conjunction with the fastness problem, solved ventilative inhomogeneous and the problem that bulk strength is not strong of existing in prior technology again effectively, make full use of the space and reduced the quality of unit volume, thereby reduced production cost; Reduced the device fabrication cost simply again because of its moulding process simultaneously, need not to spray technologies such as glue, oven dry, do not produced harmful substance in the whole process of production, environment has not been had influence.
