Multi-color synchronous paste filling machine

Abstract

The embodiment of the invention discloses a multi-color synchronous paste filling machine which comprises a plurality of material barrels, a hot runner plate connected with discharging ports of the material barrels, quantitative filling mechanisms and an end material back sucking mechanism. Each quantitative filling mechanism comprises a pump body and a plurality of needle valves, wherein the pump body is provided with multiple sets of feeding runners, deposit runners and discharging runners, the feeding runners are connected with the discharging ports corresponding to the hot runner plate, the deposit runners take and discharge materials through the needle valves, the end material back sucking mechanism is provided with discharging nozzles communicated with the discharging runners, each discharging nozzle is provided with an inner cavity, and a back sucking rod is arranged in each inner cavity. By means of the multi-color synchronous paste filling machine, the multiple quantitative filling mechanisms which conduct filling independently without mixing are used and are synchronous in action, quantitative filling of all colors is ensured, and discharging is uniform; the hot runner plate is adopted, and thus it is ensured that the materials obtain adjustable temperatures and have proper mobility; the material nozzles are provided with back sucking air cylinders, excessive materials in the material nozzles are sucked back, and the defect of material dripping is overcome.

Description

technical field [0001] The invention relates to a paste filling machine, in particular to a multi-color synchronous paste filling machine. Background technique [0002] With the development of social economy, all walks of life in the industry have further requirements for product quality and production efficiency. In the cosmetics industry, the factory daily produces a large number of multi-colored products in a box (disc), and a box (disc) is divided into several small areas, and each area is filled with a paste of a color, such as figure 1 As shown, usually, the production of this kind of products is still done by hand, filling one color at a time and filling in multiple processes, that is, filling one color and then filling another color, which generally has the following disadvantages: low efficiency, and the transformation of each process takes up a lot of space in the factory building 1. When there is a process error, it will become a waste product. The filling points...
