Description

Technical Field

[0001] The utility model relates to a pressing machine, in particular to a pressing machine for hot melt adhesive production, belonging to the technical field of hot melt adhesive production. Background Art

[0002] The hot melt adhesive production press is a device used for hot melt adhesive spraying, dispensing, pouring, bonding, edge sealing and other processes. Its working principle is to heat the solid hot melt adhesive into liquid through the heating element, and then spray, dispense or pour the liquid hot melt adhesive onto the substrate through air pressure, so as to achieve bonding, edge sealing and other functions. To ensure the use effect of the press, the hot melt adhesive remaining on the press should be removed frequently when the press is in use.

[0003] According to a Chinese patent document with announcement number CN215095888U, a pressing machine for producing polyurethane hot melt adhesive is disclosed. The device includes a platform, a support leg, a movable plate, a mounting box, a sliding part, an electric slide, a connecting rod, a fixed block, a rolling shaft, a pressing plate, an elastic part and a shovel bar. The utility model can timely scrape off the hot melt adhesive stuck on the pressing tooling through the mounting box, the sliding part and the shovel bar, thereby ensuring the quality of the hot melt adhesive, and playing a buffering role through the pressing plate and the elastic part.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it is found that when the above equipment is used, the sliding part drives the shovel bar to slide on the surface of the pressure plate, so as to timely scrape off the hot melt adhesive left on the pressure plate and ensure the quality of the hot melt adhesive. However, when the shovel bar slides on the surface of the pressure plate, the scraped hot melt adhesive will be left in the installation box, and this device can only scrape the bottom wall but not the side wall.

DETAILED DESCRIPTION

[0025] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0026] like Figure 1-Figure 6 As shown, the hot melt adhesive production press provided in this embodiment includes a base plate 1 and two vertical plates 2, the two vertical plates 2 are fixedly connected to the base plate 1, a flip plate 3 is provided on the base plate 1, a plurality of box bodies 4 are fixedly connected to the flip plate 3, a rotating rod 10 is rotatably connected to the side walls of one side of the two vertical plates 2, a cross support plate 11 is fixedly connected to the end of the rotating rod 10 away from the vertical plate 2, the flip plate 3 is fixedly installed on the cross support plate 11 by bolts, a plurality of box bodies 4 are fixedly connected to the flip plate 3 for use as a whole, and when the flip plate 3 is fixedly connected to the cross support plate 11 by bolts, it can be disassembled at any time, and a flip assembly 5 for flipping the flip plate 3 is provided on the two vertical plates 2;

[0027] A hydraulic rod 6 is fixedly installed on the base plate 1, and a lifting plate 7 is slidably connected to the two vertical plates 2. The lower end surface of the lifting plate 7 is fixedly connected to the movable end of the hydraulic rod 6. The lifting plate 7 is provided with a side wall scraping component 8 for scraping the inner side wall of the box body 4, and the lifting plate 7 is provided with a bottom wall scraping component 9 for scraping the inner bottom wall of the box body 4.
