Circular-truncated-cone injection bonding machine

Abstract

The invention discloses a circular-truncated-cone injection bonding machine which is used for producing a cylindrical packaging product in a packaging industry, and the circular-truncated-cone injection bonding machine comprises a base, an equant intermittent rotary system which is installed on the base, a mold assembly and an ejector demolding mold, which are installed on a circular-truncated-cone plate, a mold shaft fixing mechanism which is fixedly installed on the base, a correction system with a correction mold, an injection system with an injection needle nozzle and a heating drying device. The circular-truncated-cone injection bonding machine is simple to operate, stable in performance, rapid and accurate to align, rapid in workpiece machining speed and high in production efficiency.

Description

Technical field [0001] The invention relates to a machine for producing packaging products, in particular to a round table top glue injection and bonding machine for producing cylindrical packaging products. Background technique [0002] At present, the production of cylindrical packaging products is applied to a plastic injection packaging machine, which includes a base, a bearing base fixedly installed on the base and a mold shaft, a total of twelve sets. The mold shaft has an external thread and is screwed to the mold shaft. On the mold, each mold corresponds to a needle nozzle and a solenoid valve, and each mold size corresponds to only one product specification. The ejector ejection device is fixedly connected together, and the bracket installed on the base is hinged on the bracket. There are two needle discs. The needle discs are arranged horizontally above the product. Glue tanks, solenoid valves and needle nozzles are installed on the bracket. There are twelve needle nozz...

AI Technical Summary

Problems solved by technology

[0003] 1. The mold shaft has an external thread, and the mold screwed on the mold shaft leads to a relatively long working time for mold change and adjustment

[0004] 2. Each mold only corresponds to a product of one specification, and the ejector ejection device is fixedly connected together. This structure leads to too high mold cost and increases work for mold storage management.

[0005] 3. Each mold is equipped with a needle nozzle and a solenoid valve correspondingly, resulting in too long working hours for adjusting the needle nozzle, complicated machine structure and high production cost

[0006] 4. Adopting the structure of the needle plate, the injection accuracy of the needle nozzle is relatively low, and it is difficult to adjust

[0007] 5. The needle plate is set relatively horizontally above the product, which makes it impossible to install a heating device on the product. When the weather is cold, the glue dries very slowly, and sometimes it takes a while to perform the second cycle. lead to lower work efficiency

[0008] 6. Putting the product into the cylinder by hand cannot guarantee the concentricity of the product and the mold. If the length of the cylinder is within 100mm, it is relatively concentric. If the length is more than 100mm or even 400mm, it will not be concentric. If it is not concentric, the injection will It will produce deflection and leave traces of glue, so that the grade of the product will be relatively reduced a lot

[0009] 7. The needle plate hinged on the bracket, the needle plate is opened to take out and put in the product, and the glue is injected on the cover. There is a certain distance between the two needle plates, and the workers have to walk back and forth to work, and they have to open and cover Lowering the dial will make you tired after a long time, and if you are tired, the efficiency will be low

[0010] The deficiencies above make the production with this machine make the workers feel tired and have a lot of adjustment and preparation work, the production efficiency is relatively low, the injection accuracy is relatively low, and the products produced are of low grade.
