Description

A quantitative packing scale for function masterbatch packing
Technical Field
The invention relates to the field of masterbatch packing scales, in particular to a quantitative packing scale for packing functional masterbatch.
Background
The color master batch is called color master batch and also called color seed, and is a special colorant for novel high polymer materials, also called pigment preparation. The color master is mainly used for plastics. Color concentrates are composed of three basic elements, a pigment or dye, a carrier and additives, and are aggregates prepared by uniformly supporting an excessive amount of pigment in a resin, and can be referred to as pigment concentrates, so that they have a higher tinctorial strength than the pigment itself. During processing, a small amount of color master batch is mixed with uncolored resin, and colored resin or products with designed pigment concentration can be obtained.
Automatic quantitative packing scale is often applied to the automatic quantitative packing of industrial and agricultural automated production, and whole weighing process is controlled by the computer, accomplishes automatically: when the quantitative packaging scale enters an automatic operation state, the weighing control system opens the feeding door to start feeding, and the feeding device adopts a fast and slow two-stage feeding mode; when the weight of the material reaches a set value of fast feeding, stopping fast feeding and keeping slow feeding; when the weight of the material reaches a final set value, closing the feeding door to finish the dynamic weighing process; at the moment, the system detects whether the bag clamping device is in a preset state, when the packaging bag is clamped, the system sends a control signal to open the discharge door of the weighing hopper, the material enters the packaging bag, and the discharge door of the weighing hopper is automatically closed after the material is completely discharged; the bag clamping device is loosened after the materials are emptied, and the packaging bag automatically falls down; and after falling down, the packaging bags are sewed and conveyed to the next station. The automatic operation is repeated in such a cycle.
The color masterbatch is very easy to fall off attached pigment and adhere to the quantitative packaging scale in the packaging process by using the quantitative packaging scale due to the relation of the material of the color masterbatch, and particularly, the color masterbatch is used for feeding materials, so that when different batches of color masterbatches are packaged by using the quantitative packaging scale, the color masterbatches of different batches are very easy to cross-pollute due to the falling and adhering pigment, the finished product quality of the final color masterbatch is influenced, and the normal processing of the color masterbatch is influenced.
Disclosure of Invention
1. Technical problem to be solved
Aiming at the problems in the prior art, the invention aims to provide a quantitative packing scale for packing functional color master batches, which can realize that the surface pigment of the color master batches is not easy to fall off, the pigment mixing pollution among the color master batches in different batches is not easy to cause, and the normal processing of the color master batches is not easy to be influenced in the process of packing the color master batches by using the quantitative packing scale.
2. Technical scheme
In order to solve the above problems, the present invention adopts the following technical solutions.
A quantitative packing scale for packing of function masterbatch, includes feed hopper, place in the feed hopper with self assorted adhesive tape pad, adhesive tape pad includes the cushion main part, bury the inflation net in the cushion main part underground, the inflation net has the trend of outside inflation all the time, the inner wall fixedly connected with protection rubber tube blanket that adheres to the cushion, protection rubber tube blanket includes a plurality of protection rubber tubes, a plurality of protection rubber tubes all include the stereoplasm stiff end, the one end that the stereoplasm stiff end is close to the cushion main part runs through the cushion main part surface and extends to in the cushion main part and expansion net fixed connection, adjacent the one end that the cushion main part was kept away from to the stereoplasm stiff end interweaves together and forms stable three-dimensional spatial structure, the one end fixed connection elasticity spiral end that the cushion main part was kept away from to the stereoplasm stiff end is adjacent intertwine together between the elasticity spiral end, the method can realize that the surface pigment of the color master is not easy to fall off in the process of packaging the color master by using the quantitative packaging scale, the pigment mixing pollution among the color masters of different batches is not easy to cause, and the normal processing of the color master is not easy to be influenced.
Furthermore, the elastic spiral end is in a three-dimensional spiral shape, the adjacent elastic spiral ends are mutually wound, and the wound elastic spiral ends can increase the self impact resistance, so that the whole structure of the elastic spiral end is not easy to generate inelastic deformation under the action of falling functional color master batches, and the whole work of the protective rubber tube blanket is not easy to be influenced.
Furthermore, the elastic spiral end comprises a rubber tube main body, an elastic cavity is formed in the rubber tube main body in a chiseled mode, the elasticity of the elastic spiral end is improved, the collision between the functional color master batch and the elastic spiral end is flexible collision, and the loss of the functional color master batch in the packaging process is reduced.
Furthermore, the rubber hose body is filled with nitrogen at standard atmospheric pressure, when the functional color master batch captured in the protective rubber hose blanket needs to be cleaned, the protective rubber hose blanket can be directly heated by the air heater, so that the temperature of the end part of the elastic spiral is increased under the action of hot air, the end of the elastic spiral is straightened under the action of the nitrogen with increased pressure, and the functional color master batch is conveniently released from the protective rubber hose blanket.
Further, fixedly connected with adheres to the net on the outer wall of rubber tube main part, the one end that adheres to the net and is close to the rubber tube main part is buried underground at the rubber tube main part, increases the intensity of rubber tube main part through adhering to the net for the rubber tube main part is difficult for tearing the fracture under the exogenic action, is difficult for causing elasticity spiral end part to drop, is difficult for mixing in the packing of function masterbatch, is difficult for causing the pollution to the function masterbatch.
Furthermore, the attachment net is formed by weaving high-elasticity fibers, so that the influence of the attachment net on the overall deformation of the rubber hose main body is reduced, and the overall elasticity of the elastic spiral end is not easily influenced.
Furthermore, the outer surface of the rubber tube main body is coated with a hydrophobic coating, the hydrophobic coating is soaked on the surface of the adhesive net, the affinity between the surface of the elastic spiral end and the pigment on the surface of the functional color master batch can be reduced by the hydrophobic coating, and the possibility that the pigment adhered to the functional color master batch falls off is greatly reduced.
Furthermore, the hydrophobic coating is a light-colored coating, so that workers can find the protective rubber hose blanket polluted by the functional color master batches in time conveniently for maintenance, and cross contamination among different batches of functional color master batches is avoided.
Further, it is a plurality of ribs that prevent slipping that adhere to the one end fixedly connected with that the cushion is close to feed hopper, a plurality of the cross-section of preventing the rib that slips all is triangle-shaped, increases feed hopper and the frictional force that adheres to between the cushion by a wide margin for difficult emergence is skidded between adhering to the cushion and the feed hopper.
Further, adhere to the cushion and prevent beating the smooth muscle and all select for use high elasticity rubber to make, increase the elastic deformation ability of adhering to the cushion and preventing beating the smooth muscle by a wide margin for adhere to the whole inner wall of changeing the laminating feeding funnel of cushion.
