Automatic packaging heat-sealing equipment capable of controlling heat-sealing angle to avoid overlarge local pressure

Abstract

The invention relates to the technical field of automatic packaging, and provides automatic packaging heat-sealing equipment capable of controlling the heat-sealing angle to avoid overlarge local pressure. The automatic packaging heat-sealing equipment comprises a shell, a rotating block is movably connected to the interior of the shell, a roller is movably connected to the surface of the rotating block, and a movable clamp is movably connected to the surface of the roller. According to the automatic packaging heat-sealing equipment capable of controlling the heat-sealing angle to avoid the overlarge local pressure, a heat-sealing block enables a metal sliding piece to deflect, the metal sliding piece changes the resistance value of a rheostat, the metal sliding piece deflects towards a comparison plate, the resistance value of the rheostat is increased, the magnetic force of an electromagnet is decreased, a rack plate is far away from an electromagnet, a conversion wheel is made to rotate, the angle of the heat-sealing block is indirectly adjusted by changing the orientation of a guide rail through the conversion wheel, a threaded column rotates while the rack plate moves, the conversion wheel ascends by a small distance under the combined action of the threaded column and a threaded sleeve, meshing of the rack plate and the conversion wheel is not affected, and the situation that a packaging bag is pressed through and broken due to too large local pressure is avoided.

Description

technical field [0001] The invention relates to the technical field of automatic packaging, in particular to an automatic packaging heat-sealing device that controls the heat-sealing angle to avoid excessive local pressure. Background technique [0002] Automated packaging is the use of automated devices to control and manage the packaging process, so that it can be carried out automatically according to pre-specified procedures. Packaging has a certain impact on product sales. Automated packaging can not only improve production efficiency, ensure product quality, but also improve the working environment, energy saving and environmental protection. , Automated packaging plays an important role in food processing and drug protection. [0003] In the existing technology, the heat-sealing plate will be deformed under the influence of thermal stress for a long time. The products no longer have good protection, the packaging bag will be unusable and wasteful, and the sealing par...

Problems solved by technology

[0003] In the existing technology, the heat-sealing plate will be deformed under the influence of thermal stress for a long time. The products no longer have good protection, the packaging bag will be unusable and wasteful, and the sealing part is polluted so that the part that should be bonded by thermal fusion is not sealed. Therefore, an automatic packaging that controls the heat sealing angle to avoid excessive local pressure Heat sealing equipment came into being
