A glue gun is a tool for applying glue (or squeezing glue). It may be used wherever glue is needed. It is widely used in building decoration, electronic appliances, automobiles and auto parts, ships and containers and other industries.

[0003] Most of the existing glue guns are manual glue guns, and the operator of the manual glue gun presses the plate with his hand to apply glue. The operator applies glue by squeezing the rubber hose, which is laborious. In addition, when using a manual glue gun to apply glue, the operator cannot ensure that the force used is the same each time. Therefore, it will be affected by the size of the pressing pressure, and it is difficult to stably control the glue speed, which makes it difficult to apply a uniform colloid, affecting the gluing effect.

[0032] See also Figures 1 to 6 The embodiment of the present application provides a labor-saving glue gun for polyurethane silicone, including a shell 1, a top glue disk 21, a push rod 2, a control device 3, and a driving device 4. A glue barrel 11 is provided in the shell 1, and a top glue disk 21 is provided in the glue barrel 11. A push rod 2 is provided on the top glue disk 21, and a rack 22 is provided on the push rod 2; a control device 3 is installed at one end of the shell 1, and the control device 3 includes a protective shell 31, and a first connecting rod 32 is provided on the inner wall of the protective shell 31, and a rocker 33 is rotatably connected to the first connecting rod 32, and the top of the rocker 33 passes through the protective shell 31 through a first through hole 34, and a ratchet 35 is rotatably connected to the first connecting rod 32, and a driving pawl 36 is also provided on the rocker 33, and the driving pawl 36 is located above the ratchet 35, and the ratchet 35 is connected to a gear 38 through a rotating shaft 37, and the gear 38 is adapted to the rack 22; a driving device 4 is arranged on the protective shell 31, and the driving device 4 is connected to the rocker 33, and is used to drive the rocker 33 to swing; the shell 1 also includes a lower cover 12, and a glue outlet 121 is provided on the lower cover 12.

[0033] Principle of operation: The driving device 4 is used to operate the rocker 33, so that the driving pawl 36 on the rocker 33 rotates, thereby driving the ratchet 35 located below the driving pawl 36 to rotate. The rocker 33 is shaken once, driving the driving pawl 36 to rotate once, and then driving the ratchet 35 to rotate one step. The gear 38 is connected to the ratchet 35 through the rotating shaft 37. When the ratchet 35 rotates one step, the gear 38 also rotates once. Since the position of the gear 38 is fixed, the rack 22 matching the gear 38 is displaced once when the gear 38 rotates once. The rack 22 is set on the push rod 2, so the push rod 2 is displaced once, thereby driving the glue ejector plate 21 to eject the glue in the glue barrel 11 to achieve glue application.

[0034] Specifically, Figure 2 As shown, the rocker 33 is shaken once, driving the pawl 36 to push the ratchet 35 downward, and the ratchet 35 rotates one step in the clockwise direction, and the gear 38 rotates one step in the clockwise direction accordingly. Since the gear 38 is fixed and the rack 22 is movable, when the gear 38 rotates one step in the clockwise direction, the rack 22 moves one step forward to the left, that is, the rack 22 moves one step forward in the glue discharge direction, thereby pushing the top glue plate 21 to achieve glue application.

[0035] In one embodiment, Figure 4 As shown, the driving device 4 includes a slideway 41, a slider 42 is provided on the slideway 41, a fourth connecting rod 43 is provided on the slider 42, the other end of the fourth connecting rod 43 is connected to the rocker 33, and a driving motor 44 is connected to the slider 42. The driving motor 44 is started, and the driving motor 44 drives the slider 42 to slide on the slideway 41. The slider 42 is connected to the rocker 33 through the fourth connecting rod 43, so that the sliding of the slider 42 drives the rocker 33 to rock, thereby replacing the manual rocking of the rocker 33, saving time and effort.

[0036] In one embodiment, preferably, Figure 5 As shown, the control device 3 also includes a brake pawl 39, which is connected to the inner wall of the protective shell 31, and the brake pawl 39 cooperates with the ratchet 35. The control device 3 also includes a reed 391, which is connected to the inner wall of the protective shell 31, and the reed 391 is mounted on the brake pawl 39. The brake pawl 39 is mounted on the ratchet 35, and the reed 391 is mounted on the brake pawl 39. When the ratchet 35 rotates, the brake pawl 39 and the reed 391 are lifted by the upward force. When the ratchet 35 completes a stepping action, the brake pawl 39 and the reed 391 return to their original positions, and the reed 391 presses on the brake pawl 39, and the brake pawl 39 presses on the ratchet 35, further ensuring that the ratchet 35 can only perform one stepping action at a time, ensuring stable glue discharge.

[0037] In one embodiment, Figure 6As shown, a second connecting rod 5 is provided on the inner wall of the protective shell 31, and the brake pawl 39 is rotatably connected to the second connecting rod 5. The brake pawl 39 is connected to the protective shell 31 through the second connecting rod 5, and the brake pawl 39 can rotate around the second connecting rod 5.

[0038] In one embodiment, Figure 6 As shown, a third connecting rod 6 is provided on the inner wall of the protective shell 31, and the reed 391 is connected to the third connecting rod 6. The reed 391 is connected to the protective shell 31 through the third connecting rod 6.

[0039] In one embodiment, Figure 3 As shown, the control device 3 is provided with a second through hole 7. The second through hole 7 is arranged on a side of the protective shell 31 away from the rubber barrel 11. When the push rod 2 is long, the push rod 2 can pass through the second through hole 7 of the control device 3.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
