Description

Technical Field

[0001] This utility model relates to the field of glue delivery pipe technology, and in particular to a glue delivery pipe and a glue receiving pipe hot melt glue machine equipped with the glue delivery pipe. Background Technology

[0002] Hot melt glue machines melt solid glue granules or strips using an internal heating element and then deliver the molten glue to the spraying module via a pressure system. Upon contact with the surface of the object to be bonded, the sprayed glue rapidly cools and solidifies due to heat exchange, achieving the bonding effect. Hot melt glue machines require the use of a glue delivery hose. One end of the hose connects to the hot melt glue machine's discharge pipe, and the other end connects to the glue spray gun, which then sprays the delivered glue.

[0003] In most existing glue delivery hoses, to prevent the heated glue from cooling and solidifying during delivery, heating wire is usually wrapped around the outside of the hose. The heating wire heats the glue through the hose. However, this method of heating by wrapping the heating wire around the outside of the hose has low heat conduction, resulting in the glue near the inner wall of the hose being hotter than the glue in the center, causing uneven heating and inconvenience for subsequent glue use.

[0004] Therefore, it is necessary to propose a glue delivery pipe and a glue receiving pipe hot melt glue machine equipped with the glue delivery pipe to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a glue delivery tube and a glue receiving tube hot melt glue machine equipped with the glue delivery tube, so as to solve the problem mentioned in the background art that the heat conduction is low due to the method of heating by wrapping heating wire around the outside of the glue delivery tube. This results in the glue temperature being higher near the inner wall of the glue delivery tube and lower at the center of the glue delivery tube, leading to uneven heating of the glue and causing inconvenience for the subsequent use of the glue.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a glue delivery tube, including a glue delivery tube body, a connecting sleeve connected to the external thread of one end of the glue delivery tube body, a heat-conducting component disposed inside the connecting sleeve, the heat-conducting component including a fixing block, a heat-conducting rod, a first heat-conducting plate and a second heat-conducting plate, the bottom end of the fixing block being fixedly connected to the inside of the connecting sleeve, and the top end of the fixing block being fixedly connected to the outside of the heat-conducting rod, and one side of both the first heat-conducting plate and the second heat-conducting plate being fixedly connected to the outside of the heat-conducting rod.

[0007] Preferably, the other side of both the first heat-conducting plate and the second heat-conducting plate is in contact with the inner wall of the glue delivery tube body, and the side of both the first heat-conducting plate and the second heat-conducting plate near the inner wall of the glue delivery tube body is arc-shaped. The first heat-conducting plate and the second heat-conducting plate are alternately distributed on the outside of the heat-conducting rod.

[0008] Preferably, the fixing block, the heat-conducting rod, the first heat-conducting plate, and the second heat-conducting plate are all provided with heat-conducting wires, and the heat-conducting wires are electrically connected to a plug through wires.

[0009] Preferably, a connecting pipe is fixedly connected to the side of the connecting sleeve, and a fixing nut is rotatably connected to the outside of the connecting pipe.

[0010] Preferably, the outer surface of the rubber delivery tube body is wrapped with a rubber insulation layer, and the outer surface of the rubber insulation layer is wrapped with a heat insulation cotton layer.

[0011] This utility model also proposes a hot melt glue machine for connecting glue tubes, including a hot melt glue machine body, a discharge pipe fixedly connected to the outside of the hot melt glue machine body, and a socket fixedly connected to the outside of the hot melt glue machine body.

[0012] The inside of the fixing nut is connected to the outside of the discharge pipe by threads, the diameter of the connecting pipe is the same as that of the discharge pipe, and the plug and socket are inserted into each other.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. By setting up a heat-conducting component, since the heat-conducting rod, the first heat-conducting plate and the second heat-conducting plate are directly set inside the glue delivery tube body, the glue can be directly heated, avoiding the problem of heat loss during conduction. Furthermore, since the first heat-conducting plate and the second heat-conducting plate are staggered on the outside of the glue delivery tube body, the heating area of ​​the glue inside the glue delivery tube body can be increased, improving the heating efficiency of the glue and avoiding the problem of uneven heating of the glue, which brings convenience to the subsequent use of the glue.

[0015] 2. By using the first and second heat-conducting plates in combination, since both the first and second heat-conducting plates are arc-shaped on the side closest to the inner wall of the glue delivery tube, the rotation of the first and second heat-conducting plates can be used to scrape off the glue adhering inside the glue delivery tube when cleaning the inside of the glue delivery tube, which facilitates the cleaning of the inside of the glue delivery tube. In addition, the first and second heat-conducting plates can provide auxiliary support for the glue delivery tube, improving the pressure resistance of the glue delivery tube and thus improving the protection of the glue delivery tube.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figure 3 , Figure 4 and Figure 5 The illustrated glue delivery hose includes a glue delivery hose body 1. A connecting sleeve 2 is threaded to the outside of one end of the glue delivery hose body 1. A heat-conducting assembly is disposed inside the connecting sleeve 2. The heat-conducting assembly includes a fixing block 3, a heat-conducting rod 4, a first heat-conducting plate 6, and a second heat-conducting plate 7. The bottom end of the fixing block 3 is fixedly connected to the inside of the connecting sleeve 2, and the top end of the fixing block 3 is fixedly connected to the outside of the heat-conducting rod 4. One side of both the first heat-conducting plate 6 and the second heat-conducting plate 7 is fixedly connected to the outside of the heat-conducting rod 4. Heat-conducting wires 5 are disposed inside the fixing block 3, the heat-conducting rod 4, the first heat-conducting plate 6, and the second heat-conducting plate 7. The heat-conducting wires 5 are electrically connected to a plug 10 via wires. Since the heat-conducting rod 4, the first heat-conducting plate 6, and the second heat-conducting plate 7 are directly installed inside the glue delivery tube body 1, the glue can be directly heated, avoiding heat loss during conduction. Furthermore, since the first heat-conducting plate 6 and the second heat-conducting plate 7 are staggered on the outside of the glue delivery tube body 1, the heating area of ​​the glue inside the glue delivery tube body 1 can be increased, improving the heating efficiency of the glue and avoiding uneven heating of the glue, thus bringing convenience to the subsequent use of the glue.

[0024] The first heat-conducting plate 6 and the second heat-conducting plate 7 are both in contact with the inner wall of the glue delivery tube body 1 on their other sides. The sides of the first heat-conducting plate 6 and the second heat-conducting plate 7 closest to the inner wall of the glue delivery tube body 1 are both arc-shaped. The first heat-conducting plate 6 and the second heat-conducting plate 7 are alternately distributed on the outside of the heat-conducting rod 4. A connecting pipe 8 is fixedly connected to the side of the connecting sleeve 2, and a fixing nut 9 is rotatably connected to the outside of the connecting pipe 8. Because the sides of the first heat-conducting plate 6 and the second heat-conducting plate 7 closest to the inner wall of the glue delivery tube body 1 are both arc-shaped, the rotation of the first heat-conducting plate 6 and the second heat-conducting plate 7 can be used to scrape off the glue adhering inside the glue delivery tube body 1 during cleaning, facilitating the cleaning of the inside of the glue delivery tube body 1. Furthermore, the first heat-conducting plate 6 and the second heat-conducting plate 7 can provide auxiliary support to the glue delivery tube body 1, improving its compressive strength and thus enhancing its protection.

[0025] In addition, a rubber insulation layer 14 is fixedly wrapped around the outside of the rubber insulation layer 14, and a thermal insulation cotton layer 15 is fixedly wrapped around the outside of the rubber insulation layer 14. The rubber insulation layer 14 and the thermal insulation cotton layer 15 can be used to insulate and insulate the rubber supply hose body 1.

[0026] Finally, as Figure 1 and Figure 2 As shown, this utility model also proposes a hot melt glue dispensing machine, including a hot melt glue dispensing machine body 11. A discharge pipe 12 is fixedly connected to the outside of the hot melt glue dispensing machine body 11, and a socket 13 is also fixedly connected to the outside of the hot melt glue dispensing machine body 11. A fixing nut 9 is threadedly connected to the outside of the discharge pipe 12. A connecting pipe 8 has the same diameter as the discharge pipe 12. A plug 10 is inserted into the socket 13. When it is necessary to connect the glue dispensing tube body 1 to the discharge pipe 12 of the hot melt glue dispensing machine body 11, the fixing nut 9 can be rotated, causing the fixing nut 9 to move outside the discharge pipe 12, thereby connecting the discharge pipe 12 to the connecting pipe 8, which facilitates subsequent glue spraying operations. The plug 10 can be inserted into the socket 13 to energize the heating wire 5, allowing the heating wire 5 to convert electrical energy into heat energy to heat the glue.

[0027] Working principle: First, one end of the glue supply hose body 1 is connected to the discharge pipe 12 of the hot melt glue machine body 11 via the fixing nut 9, and the other end of the glue supply hose body 1 is connected to the glue gun. When the glue supply hose body 1 conveys glue, since the heat-conducting rod 4, the first heat-conducting plate 6 and the second heat-conducting plate 7 are directly set inside the glue supply hose body 1, they can directly heat the glue, avoiding heat loss during conduction. Furthermore, since the first heat-conducting plate 6 and the second heat-conducting plate 7 are staggered on the outside of the glue supply hose body 1, the heating area of ​​the glue inside the glue supply hose body 1 can be increased, improving the heating efficiency of the glue. This design improves the efficiency of heat dissipation and avoids uneven heating of the adhesive, facilitating its subsequent use. Furthermore, since the sides of the first heat-conducting plate 6 and the second heat-conducting plate 7 closest to the inner wall of the adhesive delivery tube 1 are both arc-shaped, the rotation of the first heat-conducting plate 6 and the second heat-conducting plate 7 can be used to scrape off the adhesive adhering to the inside of the adhesive delivery tube 1 during cleaning, thus facilitating cleaning. Additionally, the first heat-conducting plate 6 and the second heat-conducting plate 7 can provide auxiliary support to the adhesive delivery tube 1, improving its compressive strength and thus enhancing its protection.
