Description

Technical Field

[0001] This utility model relates to the technical field of hot air seam sealing machines, and in particular to a hot air seam sealing machine with safety protection function. Background Technology

[0002] Hot air seam sealing machine is mainly used for waterproofing seams of various waterproof clothing and outdoor sports products, such as raincoats, waterproof shoes and hats, tents, windbreakers, and waterproof diving suits. Its working principle is as follows: an air pump or fan blows air into the heating element for heating. The heated air then enters a hot air pipe connected to the heating element. The end of the hot air pipe is connected to a blower nozzle. Air is blown from the blower nozzle onto the hot air tape, causing it to reach its melting point. Finally, the upper and lower rubber rollers close and rotate, making the tape and fabric tightly bonded.

[0003] Existing technologies, such as the utility model patent with publication number CN211763575U, disclose a hot air seam sealing machine with safety protection function. This patent uses a frame with a crossbeam on its worktable. A hot air gun assembly is mounted on the crossbeam. An air guide pipe is mounted on one side of the hot air gun assembly, and a protective cover is mounted on the outside of the air guide pipe. A first connecting rod is mounted on the air guide pipe, with one end fixedly connected to the side of the air guide pipe near the crossbeam and the other end fixedly connected to the crossbeam. The protective cover is a U-shaped square tube, with a second connecting rod mounted on it. One end of the second connecting rod is fixedly connected to the protective cover and the other end fixedly connected to the crossbeam. This utility model device solves the problem that in existing hot air seam sealing machines, the air nozzle continuously sprays hot air outward during processing, which can easily burn the operator's hands.

[0004] In daily work, during the process of sealing materials while operating the equipment, the hot air blower continuously blows out hot air, causing the surface temperature of the hot air blower to be too high. Operators may accidentally touch the surface of the hot air blower, resulting in burns to their hands. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where operators are easily burned by accidentally touching the surface of the hot air blower. This invention proposes a hot air seam sealing machine with safety protection functions.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a hot air seam sealing machine with safety protection function, comprising a placement plate and a protective device. A controller is fixedly connected to the upper surface of the placement plate, a connecting arm is fixedly connected to the upper surface of the placement plate, a rotator is provided on the surface of the placement plate, a hot air blower is provided on the side of the connecting arm, and the protective device is provided on the surface of the hot air blower. The protective device includes a protective cover and a connecting plate. The connecting plate is fixedly connected to the surface of the hot air blower, the protective cover is provided on the side of the hot air blower, a connecting block is fixedly connected to the surface of the protective cover, a connecting groove is provided on the side of the connecting plate, the connecting block engages with the interior of the connecting groove, a locking hole is provided inside the connecting groove, and a pressure hole is provided on the surface of the connecting block.

[0007] Furthermore, a locking rod is slidably connected to the inner wall of the pressure hole, and one end of the locking rod is engaged with the inner wall of the locking hole. By setting the locking rod, the connecting block and the connecting plate can be stably connected, reducing the possibility that the connecting block may easily detach from the inside of the connecting plate during use, causing the protective cover to detach from the surface of the hot air blower.

[0008] Furthermore, a first spring is fixedly connected to the end of the clamping rod away from the clamping hole, and the end of the first spring away from the clamping rod is fixedly connected to the inner wall of the pressure hole. The first spring is provided to facilitate the application of a reset spring force to the clamping rod.

[0009] Furthermore, a pressure rod is fixedly connected to the side of the clamping rod, and the pressure rod is slidably connected to the inside of the pressure hole. By setting the pressure rod, it is convenient to move the clamping rod.

[0010] Furthermore, an adjustment device is provided on the side of the connecting arm. The adjustment device includes a connecting rod and an adjustment plate. The connecting rod is fixedly connected to the side of the connecting arm, the adjustment plate is fixedly connected to one end of the connecting rod, and the rotating rod is fixedly connected to the side of the hot air blower. A sliding groove is formed on the surface of the adjustment plate, and the rotating rod is slidably connected to the inner wall of the adjustment plate. A slider is fixedly connected to one end of the rotating rod, and the slider is slidably connected to the inside of the sliding groove. An adjustment groove is formed on the surface of the adjustment plate, and a pull groove is formed on the surface of the slider. A pull block is slidably connected to the inner wall of the pull groove. By setting the rotating rod, the hot air blower can be limited in movement, reducing the situation where the hot air blower is difficult to move and adjust during use, thus preventing the equipment from being unable to effectively seal materials of different thicknesses.

[0011] Furthermore, an adjusting rod is fixedly connected to the side of the pull block, and the adjusting rod engages with the inside of the adjusting groove. The adjusting rod facilitates the restriction of the pull block.

[0012] Furthermore, a second spring is fixedly connected to the surface of the connecting block. The end of the second spring away from the connecting block is fixedly connected to the inside of the groove. The second spring is provided to facilitate the application of a reset force to the connecting block.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, during use, the user moves and squeezes the material to be sealed using a rotary device. The hot air blower then blows hot air to seal the material. When in use, the user presses the pressure rod, which moves, causing the locking rod to move. As the locking rod moves, it causes the first spring to deform and generate elasticity, disengaging the locking rod from the locking hole. The connecting block then loses its restraint and is pulled away from the connecting groove. The moving connecting block then causes the protective cover to move away from the surface of the hot air blower. By setting up a protective device, the surface of the hot air blower is effectively protected, reducing the risk of burns from accidental contact with the hot air blower surface due to excessively high temperatures during use. This improves the safety of the equipment.

[0015] In this invention, by setting an adjustment device, when the user pulls the connecting block during use, the connecting block moves, causing the adjustment rod to move. When the connecting block moves, it causes the second spring to deform and generate elastic force. When the connecting block moves, the adjustment rod disengages from the inside of the adjustment groove, and the slider is unrestrained, pulling the hot air blower to move and causing the slider to move for adjustment. By setting an adjustment device, the hot air blower can be effectively adjusted, thus reducing the situation where the hot air blower is always fixed in one place during use, making it difficult for the equipment to effectively seal materials of different thicknesses, thereby improving the practicality of the equipment.

[0025] Specifically, a locking rod 66 is slidably connected to the inner wall of the pressure hole 65, and one end of the locking rod 66 is engaged with the inner wall of the locking hole 69.

[0026] In this embodiment: by setting the locking rod 66, the connecting block 63 and the connecting plate 62 can be stably connected, reducing the possibility that the connecting block 63 may easily detach from the interior of the connecting plate 62 during use, causing the protective cover 61 to detach from the surface of the hot air blower 5.

[0027] Specifically, a first spring 67 is fixedly connected to the end of the locking rod 66 away from the locking hole 69. The end of the first spring 67 away from the locking rod 66 is fixedly connected to the inner wall of the pressure hole 65. The first spring 67 is provided to facilitate the application of a reset spring force to the locking rod 66.

[0028] Specifically, a pressure rod 68 is fixedly connected to the side of the locking rod 66. The pressure rod 68 is slidably connected to the inside of the pressure hole 65. By setting the pressure rod 68, it is easy to move the locking rod 66.

[0029] In this embodiment: an adjustment device 7 is provided on the side of the connecting arm 3. The adjustment device 7 includes a connecting rod 72 and an adjustment plate 71. The connecting rod 72 is fixedly connected to the side of the connecting arm 3. The adjustment plate 71 is fixedly connected to one end of the connecting rod 72. The rotating rod 73 is fixedly connected to the side of the hot air blower 5. A sliding groove 75 is provided on the surface of the adjustment plate 71. The rotating rod 73 is slidably connected to the inner wall of the adjustment plate 71. A slider 76 is fixedly connected to one end of the rotating rod 73. The slider 76 is slidably connected to the inside of the sliding groove 75. An adjustment groove 74 is provided on the surface of the adjustment plate 71. A pull groove 77 is provided on the surface of the slider 76. A pull block 78 is slidably connected to the inner wall of the pull groove 77.

[0030] In this embodiment: by setting the rotating rod 73, the hot air blower 5 can be limited to move, which reduces the situation where the hot air blower 5 is difficult to move and adjust during use, thus preventing the equipment from being unable to effectively seal materials of different thicknesses.

[0031] Specifically, an adjusting rod 710 is fixedly connected to the side of the pull block 78. The adjusting rod 710 is engaged with the inside of the adjusting groove 74. The adjusting rod 710 is provided to facilitate the restriction of the pull block 78.

[0033] Working principle: When using the equipment, the user moves and squeezes the material to be sealed through the rotary device 4. The hot air blower 5 then blows hot air to seal the material. During use, the user presses the pressure rod 68, which moves and drives the locking rod 66. When the locking rod 66 moves, it causes the first spring 67 to deform and generate elastic force. The locking rod 66 then moves away from the locking hole 69, and the connecting block 63 is released from its restraint. This pulls the connecting block 63 away from the connecting groove 64, causing the protective cover 61 to move away from the surface of the hot air blower 5. By setting up the protective device 6, the surface of the hot air blower 5 is effectively protected, reducing the risk of burns to the operator's hands due to the continuous blowing of hot air from the hot air blower 5. This improves the safety of the equipment.

[0034] When the equipment is in use, the user pulls the connecting block 63, which moves the adjusting rod 710. When the connecting block 63 moves, it causes the second spring 79 to deform and generate elastic force. When the connecting block 63 moves, the adjusting rod 710 disengages from the adjusting groove 74, and the slider 76 is released from its restraint. This causes the hot air blower 5 to move, which in turn moves the slider 76 for adjustment. By setting the adjusting device 7, the hot air blower 5 can be effectively adjusted, thus reducing the situation where the hot air blower 5 is always fixed in one place during use, making it difficult for the equipment to effectively seal materials of different thicknesses. This improves the practicality of the equipment.
