Abstract
The utility model discloses a production system of energy-saving hot melt adhesives. The production system comprises a front road mixed melting device, a constant pressure device, a heat exchange device, a forming mould device, a cooling device and a post-processing device sequentially connected in series and is characterized in that the forming mould device comprises a mould and a cooling sleeve which is sheathed at the front end of the mould; a cooling bath which penetrates through the front and rear end faces of the cooling sleeve and a water outlet which is located at the lower part of the mould and communicated with the cooling bath are arranged in the cooling sleeve; the water outlet is connected with a water pump; a gap is arranged between the inner wall of the cooling sleeve and the mould; and a waterproof layer is arranged on the outer wall of the cooling sleeve. Through the cooling sleeve, air bubbles can be taken away by water flows which flow quickly, so that the air bubbles are prevented from being resided on the surfaces of the hot melt adhesives to form convex particles, the aim of improving the appearance quality of the hot melt adhesives is achieved and the performance stabilization of the hot melt adhesive bodies is ensured.
Description
Technical field
The utility model relates to the PUR production field, is specifically related to a kind of production system of energy-saving PUR.
Background technology
PUR is widely used in industries such as toy, packing, electronics, daily necessities as a kind of widely used chemical industry cementitious product.In process of production; The PUR raw material of melting state is extruded into tank through die head, meet water-cooled and solidify to form columniform hot melt colloid after but, but since the mould front end be arranged in the water; The hot melt colloid is not only inner when extruding cooling can discharge bubble; And water is heated and also can produces great amount of bubbles, if these bubbles can not in time be got rid of, then can cause the front end of bubble coalescence at mould; And along with the passing of hot melt colloid, bubble remains in the surface of hot melt colloid, and under surface tension effects, forms protruding particle, the presentation quality of serious hot melt colloid, and cause the unstable properties of hot melt colloid.
The utility model content
Deficiency to prior art; The purpose of the utility model is intended to provide a kind of production system of energy-saving PUR; Through adopting the design of coolant jacket, quick flowing water flow capable of using is taken away bubble, thereby prevents that the surface that bubble remains in the hot melt colloid from forming protruding particle; Can reach the purpose of the presentation quality that improves the hot melt colloid, and guarantee the stable performance of hot melt colloid.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of production system of energy-saving PUR; Comprise preceding road consolute device, constant-voltage equipment and the constant displacement pump, heat-exchange device, mould device, cooling device, the after-treatment device that are connected in series successively, said mould device comprises mould, is sleeved on the coolant jacket of mould front end; Be provided with the cooling bath that runs through its front/rear end, the delivery port that is positioned at the mould below and is communicated with cooling bath in the said coolant jacket, this delivery port is connected with suction pump; Be provided with the gap between the inwall of said coolant jacket and the mould, and the outer wall of coolant jacket also is provided with watertight composition.
After-treatment device comprises coating unit, de-watering apparatus, hauling machine, guillotine.
Be provided with filter in the said delivery port.
The production system of the energy-saving PUR that the utility model is set forth, its beneficial effect is:
1, through adopting the design of coolant jacket, quick flowing water flow capable of using is taken away bubble, thereby prevents that the surface that bubble remains in the hot melt colloid from forming protruding particle, can reach the purpose that improves the external appearance quality of PUR, and guarantee the stable performance of hot melt colloid;
2, through in delivery port, being provided with filter, can prevent that impurity from causing damage to suction pump, prolong its service life.
Description of drawings
Fig. 1 is the sketch map of the production system of a kind of energy-saving PUR of the utility model;
Fig. 2 is the structural representation of mould device among Fig. 1;
Wherein, 1, preceding road consolute device; 2, constant-voltage equipment and constant displacement pump; 3, heat-exchange device; 4, mould device; 41, coolant jacket; 42, cooling bath; 43, delivery port; 44, mould; 5, cooling device; 6, coating unit; 7, de-watering apparatus; 8, hauling machine; 9, guillotine.
The specific embodiment
Below, in conjunction with the accompanying drawing and the specific embodiment, the production system of the energy-saving PUR of the utility model done further describing, so that clearerly understand the utility model technical thought required for protection.
As shown in Figure 1, be the production system of the energy-saving PUR of the utility model, comprise preceding road consolute device 1, constant-voltage equipment and the constant displacement pump 2, heat-exchange device 3, mould device 4, cooling device 5, the after-treatment device that are connected in series successively.After-treatment device comprises coating unit 6, de-watering apparatus 7, hauling machine 8, guillotine 9.The PUR of being produced by this production system can reduce power consumption, more environmental protection and energy saving in use.
During production, (1) is inserted the PUR raw material and is mixed the melting stirring in the preceding road consolute device 1; (2) the PUR raw material is quantitatively extruded through constant-voltage equipment and constant displacement pump 2; (3) the PUR raw material stirs in heat-exchange device 3 with to cool off (4) PUR raw material be cylindrical hot melt colloid through 4 extrusion moldings of mould device once more; (5) the hot melt colloid being inserted cooling device 5, coating unit 6, de-watering apparatus 7, hauling machine 8, guillotine 9 successively carries out postposition and handles.
As shown in Figure 2, said mould device 4 comprises mould 44, is sleeved on the coolant jacket 41 of mould 44 front ends.Be provided with the cooling bath 42 that runs through its front/rear end, the delivery port 43 that is positioned at mould 44 belows and is communicated with cooling bath 42 in the said coolant jacket 41, this delivery port 43 is connected with suction pump.Be provided with the gap between the inwall of said coolant jacket 41 and the mould 44, and the outer wall of coolant jacket 41 also is provided with watertight composition.
Preferably, be provided with filter (figure does not show) in the said delivery port 43.Through adopting the design of filter, can prevent that impurity from causing damage to suction pump, prolong its service life.
During use, start suction pump, the PUR raw material enters in the mould 44, and from the outlet extruding and hot melting colloid of mould 44; And meanwhile, the water in the tank enters in the cooling bath 42 from the both sides of cooling bath 42, and flows out from delivery port 43.Because water velocity is very fast, thereby prevent that the surface that bubble remains in the hot melt colloid from forming protruding particle, improves the presentation quality of product, and guarantee the stable performance of hot melt colloid.
To one skilled in the art, can make other various corresponding changes and deformation, and these all changes and deformation should belong within the protection domain of the utility model claim all according to the technical scheme and the design of above description.
