Description

Technical Field

[0001] This utility model relates to the field of hot melt adhesive machine technology, specifically to a hot melt adhesive machine that facilitates hot melt adhesive extrusion. Background Technology

[0002] Hot melt adhesive, used in convenient hot melt adhesive extrusion machines, is a type of plastic adhesive whose physical state changes with temperature within a certain temperature range, while its chemical properties remain unchanged. It is non-toxic, odorless, and an environmentally friendly chemical product. Due to its solid nature, it is easy to package, transport, and store; it is solvent-free, pollution-free, and non-toxic; and its simple production process, high added value, strong bonding strength, and fast processing speed make it highly popular.

[0003] The existing technology patent announcement number CN221017086U describes a hot melt adhesive machine that facilitates hot melt adhesive extrusion. The patent utilizes a combination of a convenient hot melt machine extrusion structure and heating rods. When the first motor starts, it drives the short rod to rotate. The rotation of the short rod drives the long rod to swing up and down, which in turn drives the square plate to move up and down. The movement of the square plate drives the thin rods on both sides to move up and down. At the same time, the limiting rods on both sides slide up and down on the slides processed on the inner wall of the first shell, which drives multiple heating rods to move left and right to stir, heat and melt the adhesive, thus speeding up the melting process and making it more convenient to extrude the hot melt adhesive.

[0004] However, in practice, when the heating rod heats and stirs the hot melt adhesive material, the melted material tends to stick to the body of the heating rod. Over time, this forms an insulating adhesive layer on the heating rod, which reduces the heat transfer efficiency of the heating rod. Utility Model Content

[0005] To solve the above-mentioned technical problems, a hot melt adhesive machine that facilitates hot melt adhesive extrusion is provided. This solves the problem in the prior art where, when the heating rod heats and stirs the hot melt adhesive material, the melted material easily sticks to the body of the heating rod, forming a heat-insulating adhesive layer on the heating rod over time, which reduces the heat transfer effect of the heating rod.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a hot melt glue machine that facilitates hot melt glue extrusion, comprising a hot melt glue machine body, a heating and stirring mechanism that slides in the inner cavity of the hot melt glue machine body, a cylinder installed on one side of the hot melt glue machine body, and a nozzle installed on the other side of the hot melt glue machine body;

[0007] The heating and stirring mechanism includes a hollow mounting shell and a motor installed inside the mounting shell. The output shaft of the motor rotates out of the mounting shell and is fixed with several heating rods through a reducer. The telescopic end of the cylinder one enters the inner cavity of the hot melt glue machine body and is fixedly connected to the mounting shell. The feature is that it also includes a material cleaning mechanism for cleaning the body of the heating rods.

[0008] The adhesive cleaning mechanism includes a composite cleaning disc located below the mounting housing and a feed-and-lift mechanism located on the side of the mounting housing.

[0009] Preferably, the composite cleaning disc includes a circular movable ring, a movable plate rotating inside the movable ring, and a plurality of movable holes formed around the movable plate. A plurality of heating rods are respectively located in the plurality of movable holes, and the body of the heating rod is fitted with a scraping ring sleeve that is fixedly connected to the inner wall of the movable hole.

[0010] Preferably, the supply and lifting mechanism includes a supply slide seat that is vertically fixed to the side wall of the mounting housing and has an internal cavity, and a telescopic seat that is slidably disposed in the inner cavity of the supply slide seat. The bottom end of the telescopic seat extends out of the supply slide seat and is provided with an active rod between it and the movable ring.

[0011] Preferably, the power supply and lifting mechanism further includes a transmission rod disposed at the top of the inner cavity of the telescopic seat, and a belt is drivingly connected between the rod body of the transmission rod and the rod body of the drive rod.

[0012] Preferably, one end of the transmission rod rotatably passes through the telescopic seat and is securely fitted with a transmission gear, and a transmission gear plate that meshes with the transmission gear is vertically fixed below the inner side wall of the slide.

[0013] Preferably, a second cylinder is installed at the top of the supply slide, and the telescopic end of the second cylinder passes into the supply slide and is fixedly connected to the telescopic seat.

[0014] Compared with the prior art, the advantages of this utility model are:

[0015] (1) By setting up the adhesive cleaning mechanism, the pre-composite cleaning disc is driven to slide down by the supply and rotation lifting mechanism. The scraping ring can slide down along the heating rod body along with the moving ring, scraping and cleaning the adhesive on the heating rod, thus achieving the effect of cleaning the adhesive.

[0016] (2) By setting up the transmission rod and belt, since the distance between the transmission gear and the transmission tooth plate is longer than the length of the heating rod, when the cylinder opens and pushes the telescopic seat and the movable ring down as a whole, the scraper ring sleeve can pass through the heating rod in advance to complete the scraping and cleaning of the heating rod body. Then, during the further downward movement of the telescopic seat, the transmission gear passes through the transmission tooth plate and meshes with it. In this way, the transmission rod is rotated by force and the belt drives the active rod, which causes the movable ring to carry the movable plate to flip to one side to an inclined position, facing the nozzle. In this way, when the nozzle is opened, the water output by the nozzle can simultaneously wash the surface of the movable ring and the movable plate, thereby cleaning the adhesive material attached to the surface of the movable plate.

[0025] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0026] Reference Figure 1-6 As shown, a hot melt glue machine that facilitates hot melt glue extrusion includes a hot melt glue machine body 1, a heating and stirring mechanism that slides in the inner cavity of the hot melt glue machine body 1, a cylinder 3 installed on one side of the hot melt glue machine body 1, and a nozzle 4 installed on the other side of the hot melt glue machine body 1.

[0027] The heating and stirring mechanism includes a hollow mounting shell 2 and a motor 5 installed inside the mounting shell 2. The output shaft of the motor 5 rotates out of the mounting shell 2 and is fixed with several heating rods 6 through a reducer. The telescopic end of the cylinder 3 enters the inner cavity of the hot melt glue machine body 1 and is fixedly connected to the mounting shell 2.

[0028] After the hot melt material is added to the inner cavity of the hot melt glue machine body 1, the motor 5 and heating rod 6 are turned on. The output shaft of the motor 5 drives multiple heating rods 6 to rotate continuously, heating and stirring the hot melt glue. At the same time, the cylinder 3 is turned on. The telescopic rod of the cylinder 3 drives the mounting shell 2 to move back and forth in the inner cavity of the hot melt glue machine body 1, thereby driving multiple heating rods 6 to move left and right to stir, heat and melt, thus speeding up the melting process.

[0029] After the hot melt material is heated and extruded, open nozzle 4. Nozzle 4 will continuously output cleaning fluid into the inner cavity of the hot melt glue machine body 1, thereby achieving the cleaning effect on the inner cavity of the hot melt glue machine body 1.

[0030] However, when heating and stirring hot melt adhesive material, the melted material is easy to stick to the body of heating rod 6. Over time, an insulating adhesive layer will form on heating rod 6, which will reduce the heat transfer effect of heating rod 6.

[0031] Therefore, referring to Figure 2 , Figure 4 , Figure 5 as well as Figure 6 As shown, it is worth noting that it also includes a material cleaning mechanism for cleaning the body of the heating rod 6;

[0032] The adhesive cleaning mechanism includes a composite cleaning disc located below the mounting housing 2 and a supply and rotation lifting mechanism located on the side of the mounting housing 2;

[0033] The composite cleaning disc includes a circular movable ring 7, a movable plate 8 rotating inside the movable ring 7, and several movable holes that are opened around the movable plate 8. Several heating rods 6 are located in several movable holes respectively. The body of the heating rod 6 is fitted with a scraping ring sleeve 9 that is fixedly connected to the inner wall of the movable hole.

[0034] By setting up the adhesive cleaning mechanism, the pre-composite cleaning disc is driven to slide down by the supply and rotation lifting mechanism. The scraping ring 9 can slide down along the heating rod 6 as the moving ring 7 slides down, scraping and cleaning the adhesive on the heating rod 6, thus achieving the effect of cleaning the adhesive.

[0035] Furthermore, by utilizing the rotational characteristics between the movable plate 8 and the movable ring 7, the movable plate 8 can rotate synchronously with the heating rod 6 inside the movable ring 7, thereby reducing the resistance of the movable plate 8 to the movement of the heating rod 6 and ensuring the flexibility of the heating rod 6 in stirring the rubber material.

[0036] Furthermore, referring to Figure 5 and Figure 6As shown, it is worth noting that the supply and rotation lifting mechanism includes a supply slide 10 with an internal cavity that is vertically fixed on the side wall of the mounting housing 2 and a telescopic seat 11 that is slidably disposed in the inner cavity of the supply slide 10. The bottom end of the telescopic seat 11 extends out of the supply slide 10 and is provided with an active rod 12 between it and the movable ring 7.

[0037] A cylinder 16 is installed at the top of the slide block 10. The telescopic end of the cylinder 16 is inserted into the slide block 10 and fixedly connected to the telescopic seat 11.

[0038] When cylinder 2 16 is activated, the telescopic end of cylinder 2 16 drives the telescopic seat 11 to move downward, so that the movable ring 7, movable plate 8 and scraper ring sleeve 9 slide down along the body of heating rod 6 under the action of the active rod 12, thereby achieving the cleaning effect of the material stuck to the body of heating rod 6.

[0039] Furthermore, referring to Figure 5 and Figure 6 As shown, it is worth noting that the power supply lifting mechanism also includes a transmission rod 13 located at the top of the inner cavity of the telescopic seat 11, and a belt is used to drive the transmission rod 13 and the drive rod 12.

[0040] One end of the transmission rod 13 rotates through the telescopic seat 11 and is fastened with the transmission gear 14, and a transmission tooth plate 15 that meshes with the transmission gear 14 is vertically fixed below the inner side wall of the slide 10.

[0041] The distance between the transmission gear 14 and the transmission tooth plate 15 is longer than the length of the heating rod 6;

[0042] With the transmission rod 13 and belt in place, since the distance between the transmission gear 14 and the transmission tooth plate 15 is longer than the length of the heating rod 6, when the cylinder 16 opens and pushes down the telescopic seat 11 and the movable ring 7 as a whole, the scraper ring 9 can pass through the heating rod 6 in advance to complete the scraping and cleaning of the heating rod 6. Then, as the telescopic seat 11 moves further down, the transmission gear 14 passes through the transmission tooth plate 15 and meshes with it. As a result, the transmission rod 13 is rotated by force and the belt drives the drive rod 12, which causes the movable ring 7 to carry the movable plate 8 to flip to one side and tilt towards the nozzle 4. Thus, when the nozzle 4 is opened, the water output from the nozzle 4 can simultaneously wash the surfaces of the movable ring 7 and the movable plate 8, thereby cleaning the adhesive material adhering to the surface of the movable plate 8.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
