Description

Technical Field

[0001] The utility model belongs to the technical field of discharging machines, and more specifically, it particularly relates to a discharging machine for preparing hot melt adhesive. Background Technique

[0002] Hot melt adhesive is a kind of plastic adhesive. The basic resin of hot melt adhesive is copolymerized from ethylene and vinyl acetate under high temperature and high pressure. This resin is the main component of making hot melt adhesive. The proportion and quality of the basic resin determine the basic performance of hot melt adhesive. Within a certain temperature range, its physical state changes with the change of temperature, while its chemical properties remain unchanged. After the production of hot melt adhesive is completed, it needs to be loaded into the discharging machine, and then extruded through the hydraulic pressure of the discharging machine, so as to facilitate sub-packaging.

[0003] For example, the application number: CN202222276833.3 involves a new type of hot melt adhesive hydraulic discharging machine, including a bottom plate, a mounting frame, and an oil cylinder; the mounting frame is fixedly installed on the top of the bottom plate, the oil cylinder is vertically installed on the top of the mounting frame, and the output of the oil cylinder passes through the mounting frame and is fixedly connected with a pressing plate. A pressing barrel is arranged in the middle of the top of the bottom plate, and the pressing plate and the pressing barrel are symmetrically arranged up and down. Horizontally fixed connections are respectively arranged on both sides inside the mounting frame with a plurality of support rods, and sliding rods are respectively slidably connected inside the plurality of support rods. The utility model buffers the shaking pressing barrel, prevents the pressing barrel from loosening due to the friction between the pressing plate and the pressing barrel, which affects the discharging of hot melt adhesive. Through a plurality of rollers arranged at the bottom of the bottom plate, it is convenient to move the whole. By disassembling and inserting the first semi-circular ring and the second semi-circular ring on the support rod, the severely worn rubber block can be taken out and replaced, maintaining a good buffering effect on the sleeve rod.

[0004] Based on the existing technology, it is found that there are some deficiencies in the existing hot melt adhesive discharging machines. First of all, after the hot melt adhesive is extruded and discharged, it needs to be refilled into the discharging machine. During this refilling time, extrusion discharging cannot be carried out, so it will occupy a certain amount of time and reduce the efficiency of extrusion discharging. Secondly, after the hot melt adhesive discharging machine finishes discharging, a part of the hot melt adhesive will remain in the discharging pipe, and these residues cannot be extruded, and it will be very difficult to clean up after solidification later.
