Mechanism to Automatically Lower Heater for Sealing Packaging

Click For Summary

Discussion Overview

The discussion revolves around designing a mechanism to lower and raise a heating element for sealing small packaging made of aluminum to plastic. The context includes considerations for both automatic and manual operation, as well as the adaptation of existing machinery, such as drill press stands.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant seeks a mechanism that can lower a heater to a specific height and then automatically raise it, similar to a drill press mechanism.
  • Questions are raised about whether the heating element is fixed or rotating, the duration it should remain in the lowest position, and the force required for the operation.
  • Another participant suggests using a drill press stand as a base for the heater press, providing a link to a potential product.
  • There is a discussion about the need for a mechanism that allows for variable time settings based on the material being used, with the heating element fixed at the top.
  • Participants mention the importance of identifying the correct mechanism for lifting and lowering the heater, with references to "presses" and "eccentrics" as potential solutions.
  • A specific mechanism is highlighted as potentially suitable, but concerns are raised about the force it generates and whether it exceeds the requirements for the task.

Areas of Agreement / Disagreement

Participants express varying opinions on the best mechanism to use, with no consensus reached on a specific solution. There are multiple suggestions and considerations regarding the design and functionality of the proposed mechanism.

Contextual Notes

Participants discuss the need for variable settings based on material thickness and the force required for sealing, indicating that assumptions about these factors may affect the choice of mechanism.

Hi i need a mechanism to lower the heater to certain height then it will automatically go up. It could be auto or manual hand mechanism. In short i need a mechanism which is installed in drill press table machine to lower drill bit. But in my scenario it is heater to seal small packaging of aluminium to plastic. Thanks in advance

Welcome, shees :cool:

Is that heating element fixed or rotating around the vertical axis?
How long should the heater remain in lowest position?
Any force should be applied?
Should you be able to regulate the vertical gap between table and heater (variable thickness of material to be fused)?

You can buy drill press stands without the drill -- could you base your heater press on one of these?

Hi Sir, Thanks for response.
Yes time will be variable depend upon at which material is being used. Heating element will be fixed at top side which will move up and down towards table. There will be minimum force apply to cut aluminium sheet and paste it on plastic cup. My main problem is which mechanism to use for lifting and lowering the whole mechanism.

You are welcome :smile:

Thanks for link. I think this one will work http://507movements.com/mm_140.html
That one creates almost infinite force at the end of the stroke; you may not need that much, saving some of the trajectory of the lever by using less mechanical advantage.
You are welcome :smile:
