Problems solved by technology

However, in the welding process of soft plastics (PE, PP), there are mainly two problems due to factors such as large temperature differences on the surface of the mold. One is that the temperature difference is large and the welding is too heavy, which will cause the product to look ugly; , the welding is too light, it will lead to lax welding, affect the quality of the product, and then affect the properties of the product, and may also cause a series of adverse reactions, which cannot guarantee the stability of the product. In addition, the film plastic welding will produce pungent smell and Smoke, affecting the environment. When the film material is welded in the mold, if it cannot be taken out in time, it will also be affected by high temperature and affect the welding quality

Embodiment 1

[0026] according to Figure 1-2 A kind of self-heating mold welding device shown comprises top mold 1 and bottom mold 2, and described bottom mold 2 is arranged on top mold 1 bottom, and described top mold 1 is provided with vacuum pump 3 inside, and described vacuum pump 3 and The top mold 1 is detachably connected by threads, the top two sides of the top mold 1 are provided with hydraulic cylinders, one side of the top mold 1 is provided with a PLC controller 17, the bottom of the vacuum pump 3 is provided with a filter chamber 4, and the top mold 1 is provided with a filter chamber 4. The top of the filter chamber 4 is provided with a filter screen 18, and an activated carbon particle layer is arranged between the filter screens 18. The filter screen 18 is set to a plurality and the mesh holes gradually decrease from bottom to top, and the filter chamber 4 is set to Inverted table shape, layered filtration, good filtering effect, can filter and purify the odor generated by ...

Embodiment 2

[0030] according to Figure 5 In the shown self-heating mold welding device, the hydraulic cylinder, vacuum pump 3, solenoid valve 8, cylinder 11, upper heating plate 12, lower heating plate 15 and temperature sensor 22 are all electrically connected to the PLC controller 17, After the temperature sensor 22 detects the heating temperature of the upper heating plate 12 and the lower heating plate 15, the heating temperature of the upper heating plate 12 and the lower heating plate 15 can be intelligently controlled by the PLC controller 17. In addition, when the PLC controller 17 can control the connecting pipe 5 and the opening of the solenoid valve 8 on the branch pipe 7. When welding the material, the solenoid valve 8 on the branch pipe 7 is opened to absorb and filter the smoke generated by the material welding. After the welding is completed, the PLC controller 17 controls the cylinder 11 to drive the upper heating plate 12 shrinks, the solenoid valve 8 on the connecting p...

Abstract

The invention discloses a self-heating mold welding device. The self-heating mold welding device comprises a top mold and a bottom mold; the bottom mold is arranged at the bottom of the top mold; a vacuumizing pump is arranged in the top mold; a filter cavity is formed in the bottom of the vacuumizing pump; a connecting pipe is arranged at the bottom of the filter cavity; a sucking cover is arranged at the bottom of the connecting pipe; a separation pipe is arranged on one side of the connecting pipe; electromagnetic valves are arranged on the separation pipe and the connecting pipe; a smoke sucking cover is arranged at the bottom end of the separation pipe; open grooves are formed in the two sides of the bottom of the top mold; cylinders are arranged in the open grooves; upper heating plates are arranged at the bottoms of the cylinders; a positioning device is arranged on the outer side of the top mold; a mold groove is formed in the bottom mold; lower heating plates are arranged on the two sides of the bottom of the mold groove; and positioning holes are formed in the two sides of the mold groove. The whole device performs upper and lower heating welding on materials through a mold form, is stable in welding and fast and convenient to discharge, can suck and filter smell generated by welding, and is high in welding quality and tidy in edge.

Description

technical field [0001] The invention relates to the field of mold welding devices, in particular to a self-heating mold welding device. Background technique [0002] In medicine, food and other industries, soft plastics are usually used for packaging, and welding technology is usually used for packaging soft plastics, so the tightness of welding will directly affect the quality of products, especially in the pharmaceutical industry, for liquid medicine bags The quality of welding is especially important. However, in the welding process of soft plastics (PE, PP), there are mainly two problems due to factors such as large temperature differences on the surface of the mold. One is that the temperature difference is large and the welding is too heavy, which will cause the product to look ugly; , the welding is too light, it will lead to lax welding, affect the quality of the product, and then affect the properties of the product, and may also cause a series of adverse reactions...
