Abstract
The utility model discloses a cooling device of a perspex bar, which comprises a fan. The fan is connected with an air cooling device through a wind pipe. The air cooling device is a sealed cavity consisting of an outer wall, an inner wall, a left side wall and a right side wall. The inner wall is enclosed to form a through hole. Correspondingly, the left side wall and the right side wall are provided with a hole the size of which is the same as the size of the through hole. The inner wall is provided with a plurality of evenly distributed wind holes. The wind pipe is communicated with the inside of the outer wall. Compared with the prior art, the advantage of the utility model is that because the wind blown out by the fan is sent into the outer wall of the air cooling device through the wind pipe and the air cooling device is a sealed cavity, the wind can only be blown to the perspex bar produced from an extrusion head from the inner wall on which the wind holes are evenly distributed so that the perspex box can be cooled evenly. The continuous manufacture and production of factory can be satisfied in the one-step molding technology. The problem of the internal contractive vacuole of the perspex bar is solved well. The product quality is ensured.
Description
Technical field
The utility model relates to the cooling device in perspex bar production, manufacturing field, particularly a kind of perspex bar.
Background technology
The perspex bar utilization is very extensive, and the making of past perspex bar adopts poly (methyl methacrylate) plate turning to form mostly, and this technology has been subjected to the restriction of length, and production efficiency is low.Now adopt usually and extrude unit, the one-shot forming perspex bar has length and does not limit, and smooth surface, the characteristics that transparency is high can be fit to the requirement that goods processing is used.Perspex bar enters the delivery track moulding after passing extruder head before, must cool off through cooling system.Cooling system of the prior art, use water cooling mostly, there is very big defective in water-cooled: it can not solve the interior contractile vacuole problem in the perspex bar well, causes the perspex bar surface to shrink inhomogeneous, because of variations in temperature produces interior contractile vacuole, influence product quality.
The utility model content
Technical problem to be solved in the utility model is, at above-mentioned prior art present situation, and provide a kind of and can solve interior contractile vacuole problem in the perspex bar, make the cooling device of the perspex bar that shrinks evenly, improves the quality of products in machine glass bar surface.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of cooling device of perspex bar, comprise blower fan, and it is characterized in that: described blower fan connects an air cooler by a wind conveying pipe;
Described air cooler is a closed cavity of being made up of outer wall, inwall and left side wall, right side wall, and described inwall surrounds a through hole, correspondingly, has the hole with the identical size of described through hole on described left side wall, the right side; Described inwall is provided with some equally distributed defeated wind hole; Described wind conveying pipe feeds in the described outer wall; Described wind conveying pipe is two, is connected to forward and backward of described air cooler.
Compared with prior art, advantage of the present utility model is, because the wind that blower fan blows out, feed by wind conveying pipe in the outer wall of air cooler, and air cooler is a closed cavity, wind can only be provided with the inwall in several equally distributed defeated wind holes from it, blow to from the perspex bar of extruder head output, make that cooling evenly behind the perspex bar wind-engaging, in one-shot forming technique, can satisfy factory's serialization and make production, well solve the problem of the interior contractile vacuole of perspex bar, guaranteed product quality.

Among the figure:
1, blower fan; 2, air cooler; 3, wind conveying pipe; 21, outer wall; 22, inwall; 23, left side wall; 24, right side wall; 25, through hole; 221, defeated wind hole.
The specific embodiment
According to embodiment and accompanying drawing the utility model is described in further detail below.
As shown in Figure 1, 2, 3, a kind of cooling device of perspex bar comprises blower fan 1, and described blower fan 1 connects an air cooler 2 by a wind conveying pipe 3; The closed cavity that described air cooler 2 is made up of outer wall 21, inwall 22 and left side wall 23, right side wall 24, described inwall 22 surrounds through hole 25, correspondingly, has the circular hole with described through hole 25 identical sizes on described left side wall 23, the right side wall 24; Described inwall 22 is provided with some equally distributed defeated wind hole 221; Described wind conveying pipe 4 feeds in the outer wall 21 of described air cooler 2.
Perspex bar from the extruder head output, at the through hole 25 that passes air cooler 2 when conveying roller is carried, the cooling air that blower fan 1 blows out, feed air cooler 2 by wind conveying pipe 3, promptly in the closed cavity of forming by outer wall 21, inwall 22 and left side wall 23, right side wall 24, the inwall 22 that wind can only be provided with some equally distributed defeated wind hole 221 from it blows out, blow on the perspex bar, make the perspex bar cooling evenly, solve the problem of the interior contractile vacuole of perspex bar, guaranteed product quality.
