Abstract
The invention discloses a make-up method for color masters in the production of PVC (polyvinyl chloride) tubes. The method is implemented in a way that a color master screw conveyor for feeding color masters is additionally connected to a feeding screw conveyor of an extruder, so that the color masters are mixed with a material for preparing the PVC tubes in the feeding screw conveyor, and an effect of uniform mixing is achieved in the process of feeding; a feeding quantity control system is arranged on the feeding screw conveyor and the color master screw conveyor, so that the feeding quantity of the color masters is ensured, and the pollution to the environment caused by early-stage mixing can be avoided.
Description
Technical field
The method of allocating into and the device thereof that the present invention relates to look mother in a kind of pvc pipe production, belong to pvc pipe production equipment technical field.
Background technology
PVC is Polyvinylchlorid by name entirely, and Main Ingredients and Appearance is polyvinyl chloride, adds in addition other one-tenth to assign to strengthen its heat resistance, toughness, ductility etc.Because of the above-mentioned characteristic of PVC, many metal tubes are all substituted by pvc pipe gradually.
The production of existing pvc pipe is ripe, its by batch mixing, extruding, coolingly can become pipe, whole technique is shaped, while, along with column criterion is constantly perfect, obtains color to pvc pipe and requires also to increase gradually, existing for producing the tubing of different colours, the way that enterprise adopts is in batch mixing region, to add the look mother of different colours, because look mother is lighter, in adding the process stirring, inevitably can produce larger dust pollution, extremely difficult arranging.
Summary of the invention
The problem to be solved in the present invention is, provide that sneaking into of a kind of look mother is simple, the pvc pipe of environmental protection produce in look mother's the method for allocating into and device thereof, can overcome the deficiencies in the prior art.
Technical scheme of the present invention is:
Pvc pipe produce in look mother's the method for allocating into be that feeding spiro rod at extruder send and on defeated machine, connects separately a look female screw rod conveyor that adds look mother, look mother in sending defeated machine, is mixed with the material of preparing pvc pipe feeding spiro rod, in feeding process, realize and being mixed, and be provided with feeding amount control system on feeding spiro rod conveyer and look female screw rod conveyor, with this, guarantee look mother's input amount.
In above-mentioned pvc pipe production, look mother's the method for allocating into is, feeding spiro rod send the ridge distance of the conical screw of defeated machine to diminish gradually from loading hopper to extruder head.
In aforesaid pvc pipe production, look mother's the method for allocating into is, look female screw rod conveyor is connected to the feed zone that feeding spiro rod send defeated machine.
Pvc pipe produce in look mother allocate device into, its bag feeding spiro rod send defeated machine, send on the socket of defeated machine connect coloured female screw rod conveyor at feeding spiro rod.
In aforesaid pvc pipe production, look mother's the device of allocating into is, on look female screw rod conveyor, is connected with feed-control device.
In aforesaid pvc pipe production, look mother's the device of allocating into is, look female screw rod conveyor is connected to the feed zone that feeding spiro rod send defeated machine.
In aforesaid pvc pipe production, look mother's the device of allocating into is, feeding spiro rod send the ridge distance of the conical screw of defeated machine to diminish gradually from loading hopper to extruder head.
Compared with the prior art, the present invention is that the feeding spiro rod at extruder send and on defeated machine, connects separately a look female screw rod conveyor that adds look mother, look mother in sending defeated machine, is mixed with the material of preparing pvc pipe feeding spiro rod, in feeding process, realize and being mixed, and be provided with feeding amount control system on feeding spiro rod conveyer and look female screw rod conveyor, with this, guarantee look mother's input amount, so just can avoid mixing early stage the pollution to environment.Feeding spiro rod is sent defeated machine conical screw be processed as ridge apart from the shape that diminishes gradually from loading hopper to extruder head, such screw-rod structure not only can make material reach desired temperature in extrusion process, and can further increase the discharge of mixing uniformity and the bubble of material.On look female screw rod conveyor, be connected with feed-control device, can guarantee the ratio that look mother sneaks into like this, make it to reach production requirement.
accompanying drawing explanationfig. 1 is structural representation of the present invention.
the specific embodiment
Embodiment 1: as shown in Figure 1, pvc pipe produce in look mother allocate device into, its bag feeding spiro rod send defeated machine, feeding spiro rod send the two ends of defeated machine 1 to be respectively feed hopper 3 and extruder head 4, the improvement of this device is sneaking into the stage of look mother, it is on feeding spiro rod send the socket of defeated machine 1, to connect separately a look female screw rod conveyor 2, utilizing the female screw rod conveyor 2 of look look mother will be squeezed into feeding spiro rod send in defeated machine and mixes with the material of preparing pvc pipe, for making batch mixing more equal, look female screw rod conveyor 2 is connected to the feed zone that feeding spiro rod send defeated machine 1; On look female screw rod conveyor 2, connect feed-control device, to realize masterbatch and look mother's perfection collocation simultaneously.Simultaneously when making feeding spiro rod and send the screw thread of conical screw of defeated machine 1, its ridge distance is diminished gradually from loading hopper to extruder head, such screw-rod structure not only can make material reach desired temperature in extrusion process, and can further increase the discharge of mixing uniformity and the bubble of material.
Claims (7)
