Description

It is a kind of not shut down net-changing device quickly

Technical field

It is specifically a kind of not shut down net-changing device quickly the utility model relates to plastic extruder net-changing device technical field.

Background technique

As the consumption figure of plastic products constantly increases, waste plastic is also increasing, and the regeneration of waste plastic is Through being generallyd use by Modernized Chemical Enterprises, plastic extruder is that plastics recovery is granulated indispensable production equipment, waste plastic Regeneration and granulation is realized by plastic extruder, waste plastics can be made effectively to be recycled, bettered people's living environment.

During plastic extrusion, the plasticizing of plastic melt through a long time and heated will generate in melt and decompose residual object, In addition the impurity in raw material, they are squeezed out in head once entering, and will result in flow blockage, and defect occur in plastic products, Or even it cannot normally produce；In order to filter out sundries, so that pure melt is can smoothly enter into extrusion molding machine head usually will be in screw head Filter screen is set between portion and extrusion molding machine head, for preventing impurity and foreign matter from entering among former；When with squeezing out Between continuity, the sundries on filter screen builds up and head pressure caused to increase flow decline, and when being more than certain pressure When power, filter screen is breached, strainer failure.

Net-changing device is the component in plastic extrusion machine equipment for the impurity in filtering plastic melt, is squeezed out to extruder Melt is effectively filtered, and net-changing device is applied very extensive in casting films apparatus field；Net-changing device is broadly divided into manual draping Device, hydraulic automatic net-changing device, net belt type automatically walk web filter；The important component of net-changing device is strainer, net-changing device Composition have the strainer and a spare strainer that one uses under normal circumstances, filtering plastic is molten in process of production for strainer Impurity in body.

Existing net-changing device from demoulding head, is cleaned, renews strainer, heats up again, draws base using shutting down replacement filter screen Expect that normal production squeezes out, the operation overall process few then dozens of minutes, more then a few houres, cause raw material loss, energy waste, Production cost increases；With the development of technology, hydraulic automatic net-changing device is mostly used to carry out draping, hydraulic automatic net-changing device is by chamber Body, screen pack and hydraulic package composition, when net-changing device replaces strainer after a period of work, by hydraulic cylinder output power, Sieve plate is set to move up and down positioning, filter mesh realizes the replacement of on-line filtration net, then replaced strainer is cleaned, But hydraulic automatic net-changing device moves the position of strainer in use, using substitution strainer operation, to sealing requirements It is very high, the phenomenon that being easy to appear material leakage, and hydraulic automatic net-changing device higher cost, disassembly are inconvenient.

It is that those skilled in that art's technology urgently to be resolved is asked since above-mentioned technological deficiency exists in the prior art Topic；Therefore, one kind quickly not shut down net-changing device and is particularly important.

Utility model content

For above situation, for the defect for overcoming the prior art, the utility model provides one kind and does not quickly shut down net-changing device, The existing net-changing device of effective solution, from demoulding head, is cleaned much using shutting down replacement filter screen, renews strainer, is again risen Temperature, traction blank are squeezed out to normal production, and process is cumbersome, and raw material loss, energy waste, production cost is caused to increase；It is hydraulic The phenomenon that automatic net-changing device is very high to sealing requirements, is easy to appear material leakage, and higher cost, dismantle inconvenient problem.

The utility model is that one kind does not quickly shut down net-changing device, at outlet of extruder, which is characterized in that including with it is crowded The draping box being fixedly connected at machine front end exit out, the draping box are opened up along the longitudinal direction there are two perforative material channel, The material channel is set as spherical；

The discharge barrel for being fixedly arranged at the front end with connection of two material channels, the discharge barrel are fixedly arranged at the front end with strainer, The material channel inner rotation is equipped with switching ball, and the switching ball runs through along the vertical direction offers discharging channel, institute Switching ball is stated when turning to discharging channel front-rear direction, material channel is connected to discharge barrel, and the switching ball turns on discharging channel When lower direction, material channel and discharge barrel are closed.

Preferably, the switching storehouse being placed between two material channels is offered inside the draping box, described in two Switching ball passes through shaft and is fixedly connected with the change gear being placed in inside ConvertBox, slides along the vertical direction inside the ConvertBox The dynamic rack gear engaged with two change gears for being equipped with " Contraband " shape, the upper end of the rack, which is fixedly connected with, is placed in switching Push-pull rod on the outside of box, the push-pull rod upper end are fixed with push-pull handle, two material channels and discharge barrel under original state Connection one is in closed state in connected state, one, and when so that rack gear is mobile, two material channels can be mutual Swap status.

Preferably, the rear end of the draping box is fixed with ring flange, passes through at the extruder front end exit with ring flange Bolt is fixedly connected.

Preferably, two strainers and two discharge barrels, which run through, offers several threaded holes, the strainer and discharging Cylinder is bolted to connection.

Preferably, it is logical to run through the pair for offering and being connected to respectively with two material channels along the vertical direction for the draping box Road, two subaisles can be connected to, during the lower end of the draping box is fixed with when switching ball rotation with the discharging channel The miscellaneous material room of empty right openings setting, the miscellaneous magazine, which is slidably matched, is provided with miscellaneous magazine.

Preferably, two subaisles lead to two corresponding identical settings of material channel size, two pairs Road is slidably matched along the vertical direction and is provided with cleaner plate, and when the switching ball turns to discharging channel up and down direction, cleaner plate can It is slided up and down inside discharging channel.

Preferably, the upper end closed setting of the subaisle, the cleaner plate upper end are fixed with subaisle along vertical side To the connecting rod for the setting that is slidably matched, the upper end of the connecting rod is fixed with the pressing plate being placed on the outside of subaisle, the pressing plate with The upper end of subaisle is fixedly connected by spring.

The utility model clever structure, it is practical, it can be not required to completely via the draping operation for manually realizing strainer It wants user of service to have experience very abundant, so that the process of draping is more simple, quick, does not need to shut down during draping, greatly Big saves process, improves work efficiency, and improves the output value, saves resource；The position of strainer is not changed during draping It sets, it is very high to solve hydraulic automatic net-changing device sealing requirements, the phenomenon that being easy to appear material leakage, and cost is relatively low for the present apparatus, tears open Unload very convenient when the strainer for needing cleaning replacement, cost is relatively low for components in device, and repair and replacement are simple.
