[0031] Embodiment:

[0032] Please refer to Figure 1 - Figure 3, A hot melt adhesive machine that facilitates the replacement of the glue gun, including a control chassis 1, a hot melt adhesive tank 2, and a hot melt adhesive gun 3. One side of the control chassis 1 is fixedly connected to one side of the hot melt adhesive tank 2. An installation cavity 21 is provided on the side of the hot melt adhesive tank 2 away from the control chassis 1. A glue gun replacement mechanism is arranged inside the installation cavity 21. The glue gun replacement mechanism includes a replacement component arranged inside the installation cavity 21;

[0033] Specifically, the replacement component includes a sliding plate 41 threadedly connected to the outside of two lead screws 53. One side of the sliding plate 41 close to the hot melt adhesive tank 2 is fixedly connected with a first motor 42. The output end of the first motor 42 penetrates one side of the sliding plate 41 and is drivingly connected with a driving gear 43. Two racks 44 are slidably connected to the side of the sliding plate 41 away from the first motor 42. One end of each of the two racks 44 is fixedly connected with a positioning buckle 45.

[0034] Specifically, the two racks 44 are symmetrically arranged on the sliding plate 41. The two racks 44 are respectively arranged on the upper and lower sides of the driving gear 43, and both racks 44 are engaged with the driving gear 43.

[0035] Specifically, positioning frames 46 are fixedly connected to both sides of the hot melt adhesive gun 3, and the two positioning buckles 45 are respectively slidably connected with the two positioning frames 46.

[0036] In this solution, the first motor 42 can drive the driving gear 43 to rotate. When the driving gear 43 rotates, the racks 44 engaged with its upper and lower sides can approach or move away from each other, so as to realize the installation and separation of the positioning buckle 45 and the positioning frame 46. The driving gear 43 is rotatably connected to the sliding plate 41. The positioning buckle 45 can slide in the positioning frame 46 but cannot rotate inside it.

[0037] Please refer to Figure 1 - Figure 3 , The glue gun replacement mechanism further includes a movable component arranged inside the installation cavity 21. The movable component includes a bracket 51 slidably connected inside the installation cavity 21 and two lead screws 53 rotatably arranged inside the bracket 51.

[0038] Specifically, two second motors 52 are fixedly connected to one side of the bracket 51. The output ends of the two second motors 52 penetrate one side of the bracket 51 and are respectively drivingly connected to one end of the two lead screws 53.

[0039] Specifically, two electric push rods 54 are fixedly connected to the bottom end of the inner wall of the installation cavity 21. The telescopic ends of the two electric push rods 54 are fixedly connected to the bottom surface of the bracket 51.

[0040] In this solution, two second motors 52 can make two lead screws 53 rotate. Two threaded sleeves are fixedly connected to one side of the sliding plate 41, so that the sliding plate 41 can slide on the lead screw 53 when the lead screw 53 rotates. The electric push rod 54 can push the bracket 51 to move up and down in the installation cavity 21.

[0041] Please refer to Figure 1 and Figure 4 As shown in the figure, a receiving box 6 is fixedly connected to the side of the hot melt adhesive box 2 away from the control chassis 1. A placing block 61 is fixedly connected to the inside of the receiving box 6. A number of storage cavities 62 are opened at the top of the placing block 61. A sliding cover 63 is slidably connected to the top of the receiving box 6.

[0042] Specifically, the sliding cover 63 is arranged below the hot melt adhesive gun 3.

[0043] In this solution, the shapes of a number of storage cavities 62 are respectively the same as the bottom shapes of different models of hot melt adhesive guns 3. After the hot melt adhesive gun 3 enters the storage cavity 62, a part of the bottom of the hot melt adhesive gun 3 enters the storage cavity 62, and the positioning frame 46 cannot enter the storage cavity 62, so the positioning frame 46 will be placed on the top of the placing block 61. The sliding cover 63 is convenient for the staff to open, and when gluing, the staff can also place the product to be glued on the top of the sliding cover 63.

[0044] Working principle: In the initial state, the electric push rod 54 jacks up the bracket 51, the hot melt adhesive gun 3 is located above the sliding cover 63, and the sliding plate 41 is located in the middle of the bracket 51;

[0045] When the hot melt adhesive gun 3 needs to be replaced, the staff first slides the sliding cover 63 open, then selects a suitable storage cavity 62 according to the model of the installed hot melt adhesive gun 3, then turns on the second motor 52 to make the lead screw 53 rotate, so that the installed hot melt adhesive gun 3 moves above the appropriate storage cavity 62. Then the staff turns on the electric push rod 54 to lower the bracket 51 and make the hot melt adhesive gun 3 enter the storage cavity 62. Then the staff turns on the switch of the first motor 42 to separate the positioning buckle 45 from the positioning frame 46. Then the staff detaches the glue delivery pipeline of the hot melt adhesive gun 3 from the hot melt adhesive box 2, and again takes out a new hot melt adhesive gun 3 from another storage cavity 62 through controlling the electric push rod 54, the second motor 52 and the first motor 42, and resets each component in the glue gun replacement mechanism. Then connecting the glue delivery pipeline of the new hot melt adhesive gun 3 to the hot melt adhesive box 2 can complete the replacement.

[0046] The above is only the preferred specific implementation manner of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent replacement or change, and should be covered by the protection scope of the present invention.
