Systems with external heat-seal assembly height adjustment control and related seal assemblies

A packaging system, comprising:

• (a) a heat seal assembly with a heat seal contact member located in a housing;
• (b) a first mounting bracket mounted in stationary position within the housing;
• (c) a second mounting bracket located under the first mounting bracket;
• (d) an actuation system disposed between the first and second mounting brackets to horizontally shift the second mounting bracket between an extended RUN position and a retracted HOME position;
• (e) a third mounting bracket on which the heat seal assembly is mounted;
• (f) a vertical actuator interconnecting the second and third mounting brackets;
• (g) a user interface disposed external to the housing to operate the vertical actuator to move the seal assembly between an upper retracted HOME position and a lowered RUN position.

A packaging system, comprising:

• a heat seal assembly with a heat seal contact member located in a housing;
• a user adjustment interface or member disposed external to the housing in communication with the heat seal assembly, wherein the external user adjustment interface or member directs the heat seal assembly in the housing to move vertically in response to user input;
• a rotatable shaft held in the housing either (a) attached to the external user adjustment interface or (b) in electromechanical communication with the external user adjustment interface;
• a first torque transfer member held on an internal end portion of the shaft;
• a first mounting bracket;
• a second mounting bracket under the first mounting bracket;
• first and second spaced apart bearing blocks holding the shaft, wherein the second bearing block resides in a window in the first mounting bracket and the first bearing block resides on a leg of the second mounting bracket spaced apart from the first mounting bracket to reside closer to a left sidewall of the housing;
• and
• first and second actuation cylinders residing on the second mounting bracket and under of the first mounting bracket window.

A packaging system, comprising:

• a heat seal assembly with a heat seal contact member located in a housing;
• a user adjustment interface or member disposed external to the housing in communication with the heat seal assembly, wherein the external user adjustment interface or member directs the heat seal assembly in the housing to move vertically in response to user input;
• a rotatable shaft held in the housing either (a) attached to the external user adjustment interface or (b) in electromechanical communication with the external user adjustment interface;
• a first torque transfer member held on an internal end portion of the shaft;
• wherein the shaft resides above a first mounting bracket and is attached to a second mounting bracket that is under the first mounting bracket, and wherein the shaft translates over the first mounting bracket from a HOME to a RUN position in the housing.

A packaging system, comprising:

• a heat seal assembly with a heat seal contact member located in a housing;
• a user adjustment interface or member disposed external to the housing in communication with the heat seal assembly, wherein the external user adjustment interface or member directs the heat seal assembly in the housing to move vertically in response to user input;
• a rotatable shaft held in the housing either (a) attached to the external user adjustment interface or (b) in electromechanical communication with the external user adjustment interface;
• a first torque transfer member held on an internal end portion of the shaft;
• and
• further comprising a clipper residing downstream of the housing with the heat seal assembly, wherein the housing of the heat seal assembly comprises a left sidewall facing the clipper, wherein the left sidewall comprises a horizontal wherein the shaft extends out of the left sidewall through the slot with the user adjustment interface located outside the slot external to the left sidewall, and wherein the slot has a length sufficient to allow the shaft to move back to front in the housing a distance between HOME and RUN positions.
