[0026] like Figures 1 to 4 As shown, an auxiliary support device of a box nailing machine includes a box nailing machine body 1, and the box nailing machine body 1 includes a base 101, a stapling mechanism 102 and a crossbeam 103. The stapling mechanism 102 is arranged on the upper surface of the crossbeam 103, and a support mechanism 2 for supporting the top of a carton is arranged on the front of the crossbeam 103. A card slot is opened at the bottom of the inner wall of the support mechanism 2, and a limiting mechanism 3 is slidably connected inside the card slot of the support mechanism 2; specifically, the support mechanism 2 is triggered and started by a carton placed on the upper end of the crossbeam 103, so that the support mechanism 2 and the crossbeam 103 support the top of the carton during use, thereby trying to avoid the top of the subsequent carton from collapsing during the stapling process; the position of the support mechanism 2 can be automatically adjusted and moved according to the width of the carton, so that the time spent by the support mechanism 2 in supporting the top of the carton is shortened, thereby improving the stapling efficiency of the box nailing machine, and thus improving the practicability of the device.

[0027] like Figures 1 to 4As shown, the support mechanism 2 includes a connecting rod 201, a slider 207 and an electric telescopic rod 205. A groove is provided on the upper surface of the cross beam 103. The slider 207 is slidably connected inside the groove of the cross beam 103. A contact switch 208 is provided on the upper surface of the slider 207. The height of the upper surface of the contact switch 208 is higher than the height of the upper surface of the cross beam 103. The connecting rod 201 is installed on the front side of the cross beam 103. A slot is provided on the side of the connecting rod 201. A support rod 202 is slidably connected inside the slot of the connecting rod 201. A contact switch 208 is provided on the front side of the support rod 202. 6. A groove is provided on the upper surface of the base 101, and the electric telescopic rod 205 is installed on the inner wall of the back side of the groove of the base 101. A connecting plate 204 is installed on the output end of the electric telescopic rod 205. The connecting plate 204 is slidably connected inside the groove of the base 101. A limit rod 203 is provided on the upper surface of the connecting plate 204. The upper surface of the limit rod 203 is installed on the lower surface of the support rod 202. The contact switch 208 is electrically connected to the control end of the electric telescopic rod 205, and the output end of the contact switch 1 206 is electrically connected to the access end of the contact switch 2 208.

[0028] Specifically, when a carton is placed on the upper surface of the crossbeam 103, the mass of the carton triggers the contact switch 208 to start the electric telescopic rod 205 to push the connecting plate 204 and the support rod 202 to move, so that the front of the support rod 202 abuts against the front inner wall of the carton, and then the position of the contact switch 1 206 is set on the front of the support rod 202, so that when the front of the support rod 202 abuts against the front inner wall of the carton, the contact switch 1 206 is triggered to turn off the contact switch 2 208 and the electric telescopic rod 205, so that the crossbeam 103 and the support rod 202 support the top of the carton during use, thereby trying to avoid the top of the subsequent carton from collapsing during the stapling process; when the nailing machine staples cartons from small to large in sequence, the position of the support rod 202 can be automatically adjusted and moved according to the width of the carton, so that the time spent by the support mechanism 2 in supporting the top of the carton is shortened, thereby improving the stapling efficiency of the nailing machine, thereby improving the practicability of the device.

[0029] like Figure 2 and Figure 4As shown, a slot is provided on the front of the crossbeam 103, and a push rod 4 is slidably connected inside the slot of the crossbeam 103. The back of the push rod 4 is installed on the front of the slider 207. The position of the push rod 4 is located on the moving path of the binding mechanism 102, and the position of the right side of the push rod 4 is parallel to the position of the right side of the slider 207; specifically, the position of the push rod 4 is located on the moving path of the binding mechanism 102, so that the binding mechanism 102 pushes the push rod 4 to drive the slider 207 to move during the movement, and then the position of the right side of the push rod 4 is parallel to the position of the right side of the slider 207, so that the binding mechanism 102 is not easy to contact the contact switch 2 208 in the process of pushing the carton to move, thereby avoiding the binding mechanism 102 from squeezing the contact switch 2 208 inside the groove of the crossbeam 103 during the movement, thereby damaging the contact switch 208.

[0030] like Figure 2 and Figure 4 As shown, a through hole is opened on the side of the slider 207 close to the binding mechanism 102, and a spring telescopic rod 5 is arranged inside the through hole of the slider 207, and the end of the spring telescopic rod 5 away from the slider 207 is installed on the inner wall of the groove of the beam 103 close to the binding mechanism 102; specifically, the spring telescopic rod 5 has the characteristic of rebounding and resetting during use, so that when the subsequent binding mechanism 102 drives the slider 207 to move inside the groove of the beam 103, the spring telescopic rod 5 pulls the slider 207 to automatically reset, so that the staff does not need to manually adjust the position of the reset contact switch 208, thereby reducing the labor consumed by the staff when operating the device.

[0031] like Figure 3 As shown, a positioning groove is provided on the lower surface of the connecting rod 201, and a U-shaped support block 6 is slidably connected inside the positioning groove, and the upper surfaces on both sides of the U-shaped support block 6 are installed on the lower surface of the support rod 202; specifically, the left and right sides of the top of the U-shaped support block 6 are installed on the lower surface of the support rod 202, so that the U-shaped support block 6 supports the part of the support rod 202 that is slidably connected to the inside of the connecting rod 201 slot, thereby minimizing the position deviation of the support rod 202 during the subsequent movement of the support rod 202 inside the connecting rod 201 slot.

[0032] like Figure 1 and Figure 2As shown, the limiting mechanism 3 includes a fixing rod 301 and a Z-shaped fixing plate 302. A sliding groove is provided on the upper surface of the connecting plate 204. The fixing rod 301 is slidably connected inside the sliding groove of the connecting plate 204. The Z-shaped fixing plate 302 is installed on the front of the stapling mechanism 102. The front of the Z-shaped fixing plate 302 is installed on the back of the fixing rod 301. The upper surface of the fixing rod 301 abuts against the lower surface of the supporting rod 202. Specifically, the Z-shaped fixing plate 302 is installed on the front of the stapling mechanism 102, so that the fixing rod 301 is synchronously driven in the process of the subsequent stapling mechanism 102 driving the carton to move. 1 is moved, so that when the subsequent carton moves to the left side of the upper end of the support rod 202, the fixed rod 301 supports the left bottom end of the support rod 202, thereby avoiding as much as possible the excessive bearing mass of the left upper end of the subsequent support rod 202, which causes the support rod 202 to be bent during use, thereby improving the service life of the support mechanism 2; the Z-shaped fixed plate 302 is installed on the front side of the stapling mechanism 102, so that the positions of the Z-shaped fixed plate 302 and the fixed rod 301 are located outside the carton stapling placement range, thereby avoiding as much as possible the subsequent limiting mechanism 3 blocking the carton from being stapled normally during use.

[0033] In summary: the quality of the carton triggers the contact switch 208 to start the electric telescopic rod 205 to push the connecting plate 204 and the support rod 202 to move, so that the front of the support rod 202 abuts against the front inner wall of the carton, and then the position of the contact switch 1 206 is set on the front of the support rod 202, so that when the front of the support rod 202 abuts against the front inner wall of the carton, the contact switch 1 206 is triggered to turn off the contact switch 2 208 and the electric telescopic rod 205, so that the crossbeam 103 and the support rod 202 support the top of the carton during use, thereby trying to avoid the top of the subsequent carton from collapsing during the stapling process; when the nailing machine staples cartons from small to large in sequence, the position of the support rod 202 can be automatically adjusted and moved according to the width of the carton, so that the time spent by the support mechanism 2 in supporting the top of the carton is shortened, thereby improving the stapling efficiency of the nailing machine.

[0034] At the same time, the Z-shaped fixing plate 302 is installed on the front side of the stapling mechanism 102, so that the fixing rod 301 is simultaneously driven to move during the subsequent stapling mechanism 102 drives the carton to move, so that when the subsequent carton moves to the left side of the upper end of the support rod 202, the fixing rod 301 supports the left bottom end of the support rod 202, thereby minimizing the subsequent support rod 202 from bearing excessive weight on the upper end of the left side, causing the support rod 202 to bend during use, thereby improving the service life of the support mechanism 2; the Z-shaped fixing plate 302 is installed on the front side of the stapling mechanism 102, so that the positions of the Z-shaped fixing plate 302 and the fixing rod 301 are located outside the carton stapling placement range, thereby minimizing the subsequent limiting mechanism 3 from blocking the carton for normal stapling during use.
