[0001] This utility model relates to the field of hot melt adhesive machines, and in particular to a hot melt adhesive machine for connecting tubes that facilitates rapid drying. Background Technology

[0002] The fully automatic hot melt adhesive spraying machine entered the Chinese market in the mid-1980s. Initially, hot melt adhesive machines were only used in small industries such as cosmetics. Later, the sanitary napkin packaging industry gradually began to use hot melt adhesive. Nowadays, automated glue dispensing equipment is widely used in industries such as household goods, diapers, sanitary napkins, automobiles, footwear, printing, and electronic product assembly.

[0003] However, existing hot melt glue machines still have some shortcomings. After the glue is applied, the workpiece can only wait to air dry, which wastes time and reduces production efficiency. At the same time, existing hot melt glue machines are inconvenient to operate, requiring manual positioning and clamping, which can easily cause burns from the glue.

[0004] Therefore, it is necessary to propose a hot melt adhesive machine for quick drying of adhesive tubes to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a hot melt adhesive machine for quick drying of adhesive tubes, in order to solve some shortcomings of existing hot melt adhesive machines. After the adhesive is sprayed, the workpiece can only wait to air dry naturally, which wastes time and reduces production efficiency. At the same time, existing hot melt adhesive machines are inconvenient to operate, requiring manual positioning and clamping, which can easily cause burns from the adhesive.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hot melt adhesive machine for quick drying of adhesive tubes, including a workbench, a movable groove is provided at the top of the workbench, a lead screw is rotatably connected between the two ends inside the movable groove, an elastic clamping seat is threaded on the outside of the lead screw, a protective cover is provided on the outside of the movable groove, the bottom end of the protective cover is fixed to the workbench, and the protective cover is U-shaped with the U-shaped opening facing downwards;

[0007] The protective cover has sliding frames that slide on both sides inside, and electric heating tubes are fixed inside each sliding frame. Connecting plates are fixed on both sides of the elastic clamping seat. Electromagnets are fixed at one end of each connecting plate away from each other, and the two electromagnets are magnetically connected to the corresponding sliding frames.

[0008] Preferably, a hot melt container is fixed at the top of the workbench, a glue tube is connected to the bottom of the hot melt container, a nozzle is connected to the bottom of the glue tube, and the nozzle extends into the protective cover.

[0009] Preferably, an electric push rod is fixed at the top of the hot melt container, the bottom end of the electric push rod extends into the interior of the hot melt container, and a sealing piston is connected to the extended end, the sealing piston slidingly engaging with the interior of the hot melt container.

[0010] Preferably, a fan is fixed on one side of the protective cover, and a vent corresponding to the fan is opened on the other side of the protective cover. The air outlet and the vent of the fan are both connected to the inside of the protective cover.

[0011] Preferably, a drive motor is fixed to one side of the worktable, and the drive shaft of the drive motor is fixedly connected to one end of the lead screw.

[0012] Preferably, the protective cover has sliding grooves on both sides along the length direction, and a slider is fixed on one side of the sliding frame, the slider slidingly engaging inside the sliding groove.

[0013] Preferably, the hot melt container is provided with an injection port.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. In the actual operation of this utility model, when the drive motor is driven, it can drive the lead screw to rotate. After the lead screw rotates, it can drive the elastic clamping seat and the workpiece to the bottom of the nozzle for glue injection. At the same time, when the elastic clamping seat moves between the two sliding frames, the electromagnet is activated. The electromagnet can connect the elastic clamping seat and the two sliding frames. When the elastic clamping seat continues to move, it can simultaneously drive the two sliding frames and the electric heating tube to move along with it, so that the heat generated by the electric heating tube always follows the workpiece, maintains heat balance, and completes the drying process. There is no need to set an electric heating tube that is the same length as the moving path, saving energy and production costs.

[0016] 2. Once drying is complete, the electromagnet is de-energized and loses its magnetic force. At this point, the two sliding frames no longer follow the movement of the elastic clamping seat. The elastic clamping seat moves between the fan and the vent to dissipate excess heat. Finally, the elastic clamping seat pulls the glue-filled workpiece out of the protective cover for easy handling. Attached Figure Description

[0021] This utility model provides, for example Figures 1-3 The hot melt adhesive machine for quick drying of adhesive tubes shown includes a worktable 1. A movable groove 8 is provided at the top of the worktable 1. A lead screw 9 is rotatably connected between the two ends inside the movable groove 8. An elastic clamping seat 10 is threaded on the outside of the lead screw 9. The workpiece is placed on the elastic clamping seat 10 and fixed by the elastic clamping seat 10 to prevent the workpiece from moving during processing.

[0022] An electric push rod 5 is fixed at the top of the hot melt container 4. The bottom end of the electric push rod 5 extends into the interior of the hot melt container 4, and a sealing piston is connected to the extended end. The sealing piston slides inside the hot melt container 4. A protective cover 2 is provided on the outside of the moving groove 8. The bottom end of the protective cover 2 is fixed on the worktable 1, and the protective cover 2 is U-shaped with the U-shaped opening facing downward.

[0023] A hot melt container 4 is fixed at the top of the workbench 1. A glue tube is connected to the bottom of the hot melt container 4. A nozzle 14 is connected to the bottom of the glue tube. The nozzle 14 extends into the protective cover 2. The protective cover 2 can support the hot melt container 4. An injection port is provided on the hot melt container 4. Glue can be injected into the hot melt container 4 through the injection port.

[0024] In the actual operation of this utility model, by activating the electric push rod 5, the electric push rod 5 extends downward, thereby driving the sealing piston to move downward. The downward movement of the sealing piston can squeeze the glue, causing the glue to be discharged downward, thus avoiding glue accumulation and residue.

[0025] A drive motor is fixed on one side of the workbench 1. The drive shaft of the drive motor is fixedly connected to one end of the lead screw 9. Sliding frames 6 are slidably fitted on both sides inside the protective cover 2. Electric heating tubes 7 are fixed inside the sliding frames 6. Connecting plates 11 are fixed on both sides of the elastic clamping seat 10. Electromagnets are fixed at one end of the two connecting plates 11 away from each other. The two electromagnets are magnetically connected to the corresponding sliding frames 6.

[0026] In the actual operation of this utility model, when the drive motor is driven, it can drive the lead screw 9 to rotate. After the lead screw 9 rotates, it can drive the elastic clamping seat 10 and the workpiece to the bottom of the nozzle 14 for glue injection. At the same time, when the elastic clamping seat 10 moves between the two sliding frames 6, the electromagnet is activated. The electromagnet can connect the elastic clamping seat 10 and the two sliding frames 6. When the elastic clamping seat 10 continues to move, it can simultaneously drive the two sliding frames 6 and the electric heating tube 7 to move along with it, so that the heat generated by the electric heating tube 7 always follows the workpiece, maintains heat balance, and completes the drying process. It is not necessary to set an electric heating tube 7 that is the same length as the moving path, thus saving energy and production costs.

[0027] A fan 13 is fixed on one side of the protective cover 2, and a vent 3 corresponding to the fan 13 is opened on the other side of the protective cover 2. The air outlet of the fan 13 and the vent 3 are both connected to the inside of the protective cover 2.

[0028] Once drying is complete, the electromagnet is de-energized and loses its magnetic force. At this point, the two sliding frames 6 no longer follow the movement of the elastic clamping seat 10. The elastic clamping seat 10 moves between the fan 13 and the vent 3 to dissipate excess heat. Finally, the elastic clamping seat 10 drives the workpiece that has been glued out of the protective cover 2 for easy handling.

[0029] The protective cover 2 has sliding grooves 12 on both sides along the length direction inside. A slider is fixed on one side of the sliding frame 6 and slides inside the sliding groove 12.
