Description

Technical Field

[0001] The utility model belongs to the technical field of waterproof glue production, and specifically relates to a hot-melt device for producing transparent waterproof glue. Background Art

[0002] All kinds of buildings have sprung up. Whether it is building a house or the later maintenance and decoration of the house, all kinds of glue are indispensable. The fixation between some special materials such as wood, paper, glass, etc. requires glue. Therefore, glue is a highly plastic adhesive. Its physical state changes with temperature within a certain temperature range. In the glue production process, hot melt devices are usually required.

[0003] Chinese patent announcement number CN214051558U discloses a hot-melt device for producing environmentally friendly waterproof glue, comprising a hot-melt device body and two heating plates, and hydraulic cylinders are installed on both sides of the bottom end of the horizontal plate. The utility model is a hot-melt device for producing environmentally friendly waterproof glue. When the scraper moves, the glue adhering to the surface of the heating plate is scraped off, so that the heating plate can act on various parts of the glue, avoiding the phenomenon that part of the glue wraps the heating plate. The device improves the hot-melt efficiency of the heating plate, embeds the plug block, the disc and the rubber ring into the inside of the discharge pipe, and the rubber ring fits the inner wall of one end of the discharge pipe, avoiding the glue from being retained in the discharge pipe during hot melting, so that the glue is stirred more evenly. When the residual glue on the inner wall of the discharge pipe needs to be cleaned, the rubber ring is first removed from the annular groove, and then the handle is held and moved back and forth, so that the disc moves back and forth inside the discharge pipe to scrape off the glue adhering to the inner wall of the discharge pipe.

[0004] With respect to the above-mentioned related technologies, the inventors have found that there are at least the following problems in the technology: when the device stirs the glue, the stirring method is too single, resulting in a small movement amplitude of the glue in the device, resulting in uneven heating of the glue, thereby affecting the hot melt efficiency of the glue, and when the glue is hot-melt inside the device, part of the glue remains on the stirring shaft and cannot be cleaned. If the cleaning is not timely, the glue will harden, which will easily affect the quality of the next batch of hot-melt glue. For this reason, we provide a hot-melt device for the production of transparent waterproof glue, which can increase the movement amplitude of the glue and ensure uniform heating. At the same time, the glue remaining on the stirring shaft can be cleaned to avoid hardened residues. Utility Model Content

[0028] By adopting the above technical solution: when stirring the raw materials, the output end of the driving motor 4 drives the first rotating rod 101 to rotate, and then drives the driving gear 104 and the first stirring rod 102 to rotate to stir the raw materials. At this time, the first rotating rod 101 drives the turntable 10 to rotate in the opposite direction through the transmission assembly, and at the same time, drives the second rotating rod 105 to make a circular motion. At the same time, in conjunction with the rotating driving gear 104, the second rotating rod 105 rotates through the driven gear 107, and then drives the second stirring rod 106 to stir the raw materials at the edge of the hot melt tube 1.

At the same time, the second bevel gear 302 is meshed with the first bevel gear 301, so that the first rotating rod 101 can be rotated while the turntable 10 is driven to rotate in the opposite direction through the transmission assembly.

[0030] In this embodiment, a first scraper 103 is fixedly connected to the outer side of one end of the first rotating rod 101 close to the discharge pipe 5, and the first scraper 103 fits the inner wall surface of the discharge pipe 5; by setting the first scraper 103, when the glue is discharged, the first scraper 103 can clean the glue attached to the inner side of the discharge pipe 5.

A plurality of high-pressure nozzles 1091 distributed at equal intervals are fixedly connected to the inner side of the fixed seat 109, and a second scraper 1092 that fits the inner wall of the hot melt tube 1 is fixedly connected to the outer side of the fixed seat 109; by setting the electric push rod 108, the high-pressure nozzle 1091 and the second scraper 1092, when the hot melt work is completed, the glue is discharged from the hot melt tube 1. When the hot melt tube 1 needs to be cleaned, the electric push rod 108 pushes the fixed seat 109 down, and at the same time, the high-pressure nozzle 1091 sprays water to the surfaces of the first rotating rod 101, the first stirring rod 102, the second rotating rod 105 and the second stirring rod 106, thereby washing the glue on their surfaces to prevent the glue from hardening and affecting the quality of the next hot melt glue, and the second scraper 1092 can clean the residual glue on the inner wall surface of the hot melt tube 1.

[0032] In this embodiment, a water tank 6 is fixedly installed on the outside of the hot melt tube 1, a winding mechanism 8 is fixedly installed on the upper end of the water tank 6, a water pump 7 is fixedly connected to the side of the water tank 6, and one end of the water pump 7 is fixedly connected to a water pipe 701, a connecting hose 9 is wound inside the winding mechanism 8, and one end of the connecting hose 9 is fixedly connected to the water pipe 701, and the other end is fixedly connected to a fixing seat 109; the water tank 6 can store the water source required for cleaning, and the water pump 7 draws the water source in the water tank 6, guides the water source to the fixing seat 109 through the water pipe 701 and the connecting hose 9, and finally sprays it through the high-pressure nozzle 1091.

[0033] In this embodiment, the winding mechanism 8 includes a fixed frame 801 and a winding drum 802.

This method can ensure that the raw materials are fully stirred, expand the movement range of the raw materials, ensure the movement of the edge raw materials, and thus ensure that the raw materials are heated evenly;

After the hot melting work is completed, when it is necessary to clean the inside, the water source in the water storage tank 6 is extracted by the water pump 7, and is guided to the connecting hose 9 through the water guide pipe 701, and finally introduced into the fixed seat 109, and sprayed through the high-pressure nozzle 1091. At the same time, the electric push rod 108 pushes the fixed seat 109 to descend, and the high-pressure nozzle 1091 is annularly distributed inside the fixed seat 109, so as to spray the first The surfaces of the first rotating rod 101, the first stirring rod 102, the second rotating rod 105 and the second stirring rod 106 are rinsed to clean the glue attached to the surfaces of the first rotating rod 101, the first stirring rod 102, the second rotating rod 105 and the second stirring rod 106 to avoid hardening of the glue and affecting the quality of the next hot melt glue.
