Description

Injection structure and liquid blending equipment Technical Field The application relates to the field of liquid dispensing equipment, in particular to an injection structure and liquid dispensing equipment. Background In many fields, a liquid blending process, such as industrially common automotive paint, emulsion paint, varnish and the like, or some liquid articles used in life, such as liquid seasonings and liquid emulsion cosmetics, are blended into a liquid mixture by multiple components, and in the blending process, particularly in the process of customizing and blending single products, different raw materials are selected for blending and mixing according to order requirements. The raw materials are generally stored in a raw material barrel, liquid raw materials in the raw material barrel are sprayed into a blending container through a spray nozzle finally through a spray pipe by using a pump valve assembly, and then the raw materials are subjected to processes such as uniform mixing and the like to prepare a required product. The injection pipe is used as a key pipeline for connecting a paint outlet pipe of a raw material barrel and a nozzle, and is convenient to pull in a certain range in the injection process so as to realize the batch injection action of the liquid blending equipment in a certain range. The injection tube of the liquid preparation equipment generally adopts a hose structure, the design improves the operation flexibility to a certain extent, but brings problems at the same time, the hose is easy to droop when being influenced by dead weight, the precision and uniformity of the nozzle are influenced, the environment is disordered, the hose can be rubbed with the ground or other objects to cause abrasion or damage of the hose, and the hose can interfere with other parts (such as a vehicle body, a vehicle frame and the like) in the moving process, so that the paint filling operation is blocked or the hose is damaged. In order to avoid the above problems, it is common today to provide a supporting point at the middle section of the hose structure, so that the hose structure is arranged in an inverted U-shape, however, the inverted U-shaped hose structure needs to occupy a lot of space, and the larger the paint filling range is, the larger the space occupied by the inverted U-shaped hose structure is. Because the hose needs to be kept at a certain length on both sides of the support point to ensure that the required nozzle travel distance can be covered. At the same time, this structure may also limit the range of movement of the operator. Disclosure of utility model The application aims to provide an injection structure and liquid blending equipment, which solve the technical problems that in the prior art, a hose is easy to sag when being influenced by dead weight, the precision and uniformity of paint spraying are influenced, the environment is disordered, the hose is possibly rubbed with the ground or other objects to cause abrasion or damage of the hose, a supporting point is arranged at the middle section of the hose structure, the hose structure is arranged in an inverted U shape, the hose structure needs to occupy a large amount of space, and the moving range of operators is possibly limited.
