Abstract
The utility model discloses a plastic profile moulding device with periodically changed sectional dimension. The device comprises an extruding main machine (1), an extruding mould head (2), a blowing device (4), a cooling tank body (5) and a cutting device, and further comprises a traction device which is characterized by comprising an upper traction caterpillar band (7), a lower traction caterpillar band (8) and a traction program control system (6). The upper traction caterpillar band (7) and the lower traction caterpillar band (8) are adapted at the rear end of the cooling tank body (5). The traction program control system controls the speed of the upper traction caterpillar band (7) and the lower traction caterpillar band (8). According to the utility model, the section can change periodically in the extruding and moulding process, so that a special moulding method is formed. The device provided by the utility model can realize extruding and moulding in single or multiple cavities, and the production efficiency is higher.
Description
Technical field
The utility model relates to the plastic irregular profile shaped device, is exactly the plastic irregular profile shaped device of realizing that the plastic irregular profile sectional dimension cycle changes.
Background technology
Plastic irregular profile is the plastic products in the irregular cross section that makes by extruding forming method, and it has wide range of applications, especially with plastic door-window typical case the most.Usually extruding when plastic irregular profile is produced is at the uniform velocity isometrical extrusion, and in the extrusion molding process, the plastic irregular profile cross-sectional sizes can not change.
In recent years, in Europe and flourishing coastal area, many pseudo-classic buildings are quietly risen.Be men of old's utility model with grass as the material on roof, because it has " cool in summer and warm in winter ", and can combine together with the Nature.Yet traditional grass easily rots usually, and is rotten, and the roof needs often renovation.Replace cogongrass if can utilize plastics to make with the product of cogongrass structural similarity, just can solve the problem that needs often to change the roof.There are characteristics on the roof of laying with cogongrass, and roof and eaves are angled, and top perimeter is short, the girth of eaves is longer.Like this, the material of need laying, different to eaves two ends diameter from the top, little, large near the diameter of eaves near the diameter at top.Because of the normally at the uniform velocity isometrical extrusion of plastic profile extrusion, realize that quantity-produced product two ends size is very difficult do cyclically-varying.
The utility model content
The purpose of this utility model solves exactly plastic irregular profile production size and makes periodically variable plastic irregular profile hard problem.
The technical solution adopted in the utility model is: the plastic irregular profile shaped device that the sectional dimension cycle changes, it comprises extrusion main unit, extrusion die, blowning installation, cooling box and cutter sweep, it also comprises draw-gear, it is characterized in that described draw-gear comprises the upper crawler belt of traction, the lower crawler belt of traction and traction program control system, in traction, crawler belt and the lower crawler belt of traction fit in the rear end of cooling box, and the traction program control system realizes that to drawing the lower crawler belt of upper crawler belt and traction speed controls.
Adopt technique scheme, control pre-set control program, draw-gear is carried out regular speed regulate, make plastic products produce speed change on lead and stretch, realize the variation of plastic products on sectional dimension.
The utility model beneficial effect is: the utility model can be realized the effect in the middle section generating period variation of extrusion molding process, is a kind of special forming method.The utility model can be realized single chamber or multi-cavity extrusion molding, and production efficiency is higher.
Description of drawings
Fig. 1 is the utility model forming device schematic diagram.
Fig. 2 is the section bar schematic diagram that this method pulls out.
Fig. 3 is the schematic cross-section of Fig. 2.
The specific embodiment
As shown in Figure 1, a kind of forming device, changes of section that can property performance period.This device mainly is comprised of extrusion main unit 1, extrusion die 2, blowning installation 4, cooling box 5, traction and cutter sweep 6, traction program control system 9.
As shown in Figure 1, goods 2 are that extrusion die 2 moulding need to obtain the molten base of shape through extrusion main unit 1 plasticizing, and molten base is tentatively cooling through blowning installation 4, and the top layer reaches elastomeric state, is in to treat extended state.Traction program control system 9 is sent variable rate signal, controls the lower crawler belt 8 of the upper crawler belt 7 of traction and traction and carries out synchronous speed change, reaches the purpose of speed change traction, realizes the goods speed change is stretched and carries out the effect that sectional dimension changes.Goods after speed change stretches, process cooling box 5 carries out further cooling, reaches glassy state and finally is cooled to room temperature state.Through hauling machine cutter sweep 6, arrive cutter sweep 10, send control signal by cutting control panel 9, goods are realized fixed length cutting.
As shown in Figure 1, traction is crawler belt 7 and 8 up and down, can realize the at the uniform velocity variation of 0.1m/min to 15m/min within the time of setting.
Show as Fig. 2 and Fig. 3, goods are in each fixed length L scope, and regular variation occurs sectional dimension.A, B, C sign place is respectively the cut point of fixed length end (or initiating terminal).Each fixed length L1, L2, L3 ... length is consistent.
Claims (1)
1. the plastic irregular profile shaped device that changes of sectional dimension cycle, it comprises extrusion main unit (1), extrusion die (2), blowning installation (4), cooling box (5) and cutter sweep, it also comprises draw-gear, it is characterized in that described draw-gear comprises the upper crawler belt (7) of traction, the lower crawler belt (8) of traction and traction program control system (6), crawler belt in traction (7) and the lower crawler belt (8) of traction fit in the rear end of cooling box (5), and the traction program control system realizes speed control to drawing the lower crawler belt (8) of upper crawler belt (7) and traction.
