[0041] Example:

[0042] See also Figure 1-2 A portable hot melt adhesive rapid heating device comprises a placement box 1 and a plurality of hot melt adhesive sticks 3, one end of the placement box 1 is fixedly connected to a preheating table 4, and the top of the placement box 1 is rotatably connected to a cover plate 2, a preheating groove 5 matching the hot melt adhesive stick 3 is provided at the upper end of the preheating table 4, a heating block 6 is installed at the bottom end of the inner wall of the preheating groove 5, a mounting groove 10 connected to the preheating groove 5 is provided on the preheating table 4, a rotating assembly 8 is arranged in the mounting groove 10, and the rotating assembly 8 comprises a rotating roller 801, and both ends of the rotating roller 801 are rotatably connected to the inner wall of the mounting groove 10.

[0043] A hot melt glue gun is a common portable hot melt glue quick heating device. Usually, after the user inserts the hot melt glue stick into the hot melt glue gun, it is necessary to turn on the power of the hot melt glue gun and wait for about two minutes of heating time to completely melt the glue stick and make the glue reach an appropriate viscosity. In actual use, when faced with a large workload of bonding work, multiple hot melt glue sticks are required, and the time waiting for the hot melt glue sticks to heat up will occupy part of the working time, thereby reducing work efficiency. In this solution, the inner cavity of the placement box 1 can be used to store multiple hot melt glue sticks 3, which is convenient for users to carry and use. When the user uses the hot melt glue gun, a hot melt glue stick 3 can be taken out in advance and placed in the preheating groove 5, and the heating block 6 can be started to preheat the hot melt glue stick 3, so that after the user inserts the preheated hot melt glue stick 3 into the hot melt glue gun, the time can be reduced. The heating time of the hot-melt glue gun on the hot-melt glue stick 3 is shortened, so that it can be used quickly. Since the user may need to consume multiple hot-melt glue sticks 3, when the user uses a hot-melt glue stick 3 on the hot-melt glue gun, the user can take out the next hot-melt glue stick 3 from the placement box 1 and put it into the preheating groove 5 in advance for preheating. In this way, when the hot-melt glue stick 3 on the hot-melt glue gun is used up, the user can immediately take out the next one from the preheating groove 5 and continue to use it, which effectively reduces the time consumed in heating the hot-melt glue stick 3. Rotating the cover plate 2 can make the cover plate 2 cover the upper ends of the placement box 1 and the preheating groove 5, and cover the hot-melt glue stick 3 in the placement box 1, so that the overall device is easy to carry, and the outer end of the ejector rod 901 is provided with a spring 902, the spring 902 is located on the outside of the preheating table 4, and the two ends of the spring 902 are respectively connected to the ejector rod 901 and the preheating table 4.

[0044] See also Figure 2 , 4 and 5, the outer surface of the rotating roller 801 is engraved with anti-slip grooves, and a part of the outer surface of the rotating roller 801 extends to the inner cavity of the preheating groove 5, the rotating component 8 also includes a servo motor 803, the servo motor 803 is installed on the inner wall of the installation groove 10, and the output end of the servo motor 803 is fixedly connected to the driving gear 804, and the outer end of the rotating roller 801 close to the driving gear 804 is fixedly connected to the driven gear 802, and the driven gear 802 is meshed with the driving gear 804.

[0045] When the user places the hot melt glue stick 3 in the preheating groove 5, the outer surface of the hot melt glue stick 3 will abut against the rotating roller 801. At this time, the user can start the servo motor 803 to drive the driving gear 804 to rotate, and the driving gear 804 drives the driven gear 802 to rotate, and then drives the rotating roller 801 to rotate. The rotating roller 801 can push the hot melt glue stick 3 to roll in the inner cavity of the preheating table 4, so that the outer surface of the hot melt glue stick 3 is evenly in contact with the heating block 6, thereby improving the preheating effect. The anti-slip pattern on the surface of the rotating roller 801 can enhance the friction between the rotating roller 801 and the hot melt glue stick 3.

[0046] See also Figure 3 A temperature sensor 7 is embedded in the inner wall of the preheating tank 5 .

[0047] The temperature of the surface of the hot melt glue stick 3 can be monitored by the temperature sensor 7. When the limit value is reached, the temperature sensor 7 can automatically turn off the heating block 6, so that the hot melt glue stick 3 remains in a heated but unmelted state, thereby preventing the hot melt glue stick 3 from being overheated and softened and being inconvenient to insert into the hot melt glue gun.

[0048] See also Figure 3 An ejector assembly 9 is provided on one side of the preheating table 4 , and the ejector assembly 9 includes an ejector rod 901 , which is slidably connected to the preheating table 4 , and one end of the ejector rod 901 extends to the inner cavity of the preheating tank 5 .

[0049] The user can push the ejector rod 901 to move the ejector rod 901 into the preheating groove 5 and squeeze the spring 902, so that the hot melt glue stick 3 in the preheating groove 5 is pushed out from one side of the preheating groove 5 by the ejector rod 901, making it easier for the user to take it out.

[0050] Working principle:

[0051] During use, the user can store multiple hot-melt glue sticks 3 in the inner cavity of the placement box 1. When the user uses the hot-melt glue gun, the user can take out a hot-melt glue stick 3 in advance and place it in the preheating groove 5, and start the heating block 6 to preheat the hot-melt glue stick 3. During the process, the outer surface of the hot-melt glue stick 3 will abut against the rotating roller 801. The user can start the servo motor 803 to drive the active gear 804 to rotate, and the active gear 804 drives the driven gear 802 to rotate, and then drives the rotating roller 801 to rotate. The rotating roller 801 can push the hot-melt glue stick 3 to roll in the inner cavity of the preheating table 4, so that the outer surface of the hot-melt glue stick 3 is evenly in contact with the heating block 6, thereby improving the preheating effect. After the user inserts the preheated hot-melt glue stick 3 into the hot-melt glue gun, the heating time of the hot-melt glue gun on the hot-melt glue stick 3 can be reduced, and then it can be used quickly. Since the user may need to consume multiple hot-melt glue sticks 3, when the user uses a hot-melt glue stick 3 on the hot-melt glue gun, the user can take out the next one from the placement box 1. The hot melt glue stick 3 is placed in the preheating groove 5 for preheating in advance. In this way, when the hot melt glue stick 3 on the hot melt glue gun is used up, the user can immediately take out the next one from the preheating groove 5 and continue to use it, which effectively reduces the time spent on heating the hot melt glue stick 3. The temperature of the surface of the hot melt glue stick 3 can be monitored by the temperature sensor 7. When the limit value is reached, the temperature sensor 7 can automatically turn off the heating block 6, so that the hot melt glue stick 3 is kept in a heated but not melted state, avoiding the hot melt glue stick 3 from being overheated and softened and inconvenient to be inserted into the hot melt glue gun. When the preheating is completed, the user can push the ejector rod 901 to move the ejector rod 901 into the preheating groove 5 and squeeze the spring 902, so that the hot melt glue stick 3 in the preheating groove 5 is pushed out from one side of the preheating groove 5 by the ejector rod 901, so that the user can take the hot melt glue stick 3 conveniently. The cover plate 2 is rotated so that the cover plate 2 can cover the upper end of the placement box 1 and the preheating groove 5, and cover the hot melt glue stick 3 in the placement box 1, so that the device as a whole is easy to carry.

[0052] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
