Abstract
The utility model discloses a kind of head of plastic extruder hydraulic screen replacing device, which solve conventional plastic cross-head net exchanging device inefficiency and the not strong technical problem of practicality.The utility model comprises screen pack, is used for fixing the screen holder of screen pack and drives oil cylinder, wherein screen pack is positioned at the inside of head, this screen holder offers the locating slot matched with screen pack, the plunger rod of this driving oil cylinder is connected with screen holder, this screen holder offers side by side two locating slots matched with screen pack, these two locating slots are positioned at head inside, and another is positioned at head outside.When filter screen changed by needs, only need to load onto screen pack at the locating slot being arranged in head outside, and by driving oil cylinder to drive screen holder motion, the screen pack being positioned at head outside to be transported to the inside of head, need the screen pack changed and clear up to be transported to the outside of head head inside simultaneously.The utility model has the high and practical feature of operating efficiency.
Description
Technical field
The utility model belongs to mechanical field, and it relates to a kind of net exchanging device, is related specifically to a kind of head of plastic extruder hydraulic screen replacing device.
Background technology
In the extrusion of extruder, fused materials is fed to mould by screen pack.Screen pack makes material be filtered, and can improve the mixed effect of material.In assembling process, the screen pack of extruder is often fixed on the baffle of a porous or groove, can make like this to form sealing between extruder and mould.But along with screen pack uses for a long time, its back pressure and melting material temperature rise, and make the increase of screen pack pressure, the amount of impurities in the resin that screen pack retains is caused to become many, thus clog filter screens.Namely the screen pack in extruder needs regular carrying out to change and clear up.The conveniently replacing of screen pack, the patent No. is that the patent of invention of 201010250023.X discloses a kind of hinged quick-open handpiece, and it can realize the quickly opening and closing of cooling machine head by linkage, facilitates draping.Although this structure simplifies traditional draping operation, when carrying out draping, still need to open head, pedestrian's work of going forward side by side draping, therefore this head of plastic extruder net exchanging device also also exists inefficiency and the not strong shortcoming of practicality.
Utility model content
The purpose of this utility model is the head of plastic extruder hydraulic screen replacing device providing a kind of operating efficiency high and practical.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of head of plastic extruder hydraulic screen replacing device, comprise screen pack, be used for fixing the screen holder of screen pack and drive oil cylinder, wherein screen pack is positioned at the inside of head, this screen holder offers the locating slot matched with screen pack, the plunger rod of this driving oil cylinder is connected with screen holder, this screen holder offers side by side two locating slots matched with screen pack, these two locating slots are positioned at head inside, and another is positioned at head outside.
Above-mentioned a kind of head of plastic extruder hydraulic screen replacing device, the housing of this driving oil cylinder is connected with fixed mount, and this fixed mount and head are fixedly linked by connecting rod.
Above-mentioned a kind of head of plastic extruder hydraulic screen replacing device, this driving oil cylinder is positioned at the side of head.
Above-mentioned a kind of head of plastic extruder hydraulic screen replacing device, this housing is provided with oil through.
The beneficial effects of the utility model are: by offering two locating slots matched with screen pack on screen holder side by side, and in these two locating slots one is positioned at head inside, another is positioned at head outside, this filtering frame is connected with driving oil cylinder simultaneously, thus when filter screen changed by needs, only need to load onto screen pack at the locating slot being arranged in head outside, and by driving oil cylinder to drive screen holder motion, the screen pack being positioned at head outside to be transported to the inside of head, need the screen pack changed and clear up to be transported to the outside of head head inside simultaneously, conveniently can complete draping operation thus.Therefore the utility model has the high and practical advantage of operating efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Further understand for making to have architectural feature of the present utility model and effect of reaching and be familiar with, coordinate detailed description in order to preferred embodiment and accompanying drawing, be described as follows:
As shown in Figure 1, a kind of head of plastic extruder hydraulic screen replacing device, comprise screen pack, be used for fixing the screen holder 1 of screen pack and drive oil cylinder 2, wherein screen pack is positioned at the inside of head 3, this screen holder 1 offers the locating slot 11 matched with screen pack, the plunger rod 21 of this driving oil cylinder 2 is connected with screen holder 1, this screen holder 1 offers side by side two locating slots 11 matched with screen pack, it is inner that these two locating slots 11 are positioned at head 3, and it is outside that another is positioned at head 3.By offering two locating slots 11 matched with screen pack on screen holder 1 side by side, and in these two locating slots 11 one to be positioned at head 3 inner, it is outside that another is positioned at head 3, this filtering frame 1 is connected with driving oil cylinder 2 simultaneously, thus when filter screen changed by needs, only need to load onto screen pack at the locating slot 11 being arranged in head 3 outside, and by driving oil cylinder 2 to drive screen holder 1 to move, the screen pack being positioned at head 3 outside to be transported to the inside of head 3, need the screen pack changed and clear up to be transported to the outside of head 3 head 3 inside simultaneously, conveniently can complete draping operation thus.Therefore the utility model has the high and practical advantage of operating efficiency.
Drive the housing 22 of oil cylinder 2 to be connected with fixed mount 4, this fixed mount 4 is fixedly linked by connecting rod 5 with head 3, namely realizes driving oil cylinder 2 to be fixed on head 3, ensures stability and its practicality of driving oil cylinder 2 work thus.
Drive oil cylinder 2 to be positioned at the side of head 3, namely realize driving oil cylinder 2 to drive screen holder 1 to move in left-right direction, the structure of the present utility model being thus is more reasonable, and carrying out dress net simultaneously and unload net operation also can be convenient.Housing 22 is provided with oil through 23, logical oily situation thus by controlling oil through 23 just can realize the motion controlling the plunger rod 21 driving oil cylinder 2, also screen holder 1 is namely driven to complete corresponding action, therefore the utility model can realize apparatus control automation draping does exercises, therefore the utility model has the high and practical advantage of operating efficiency.
In order to ensure the sealing property that screen holder 1 coordinates with head 3, in the horizontal direction of screen holder 1 and head 3, the chute and screens that match can be respectively equipped with, to ensure the reliability and stability that screen holder 1 moves, can seal washer be added simultaneously between screen holder 1 and head 3, improve sealing of the present utility model and practicality further thus.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; the just principle of the present utility model described in above-described embodiment and description; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
