[0022] Such as Figures 1 to 3As shown in the figure, the carton placement bracket for a carton stapling machine includes a base 1. Four universal wheels 2 are fixedly installed at the bottom of the base 1. Four groups of telescopic rod assemblies 3 with telescopic functions are arranged on the top of the base 1. Two groups of telescopic rod assemblies 4 with telescopic functions are arranged between every two vertically corresponding groups of telescopic rod assemblies 3. A number of fixed sleeve assemblies 5 are sleeved on each telescopic rod assembly 3. A telescopic rod 6 is arranged between every two vertically corresponding fixed sleeve assemblies 5. A driving assembly 7 is arranged on the top of the base 1 for driving two adjacent telescopic rod assemblies 4 to move away from each other, move closer to each other, and rotate. It should be noted that first, control the driving assembly 7 according to the carton size, so that the two telescopic rod assemblies 4 close to the driving assembly 7 move away from each other or move closer to each other until the distance between the two lower telescopic rod assemblies 3 is adjusted to an appropriate distance. Then, further control the driving assembly 7 so that the two telescopic rod assemblies 4 close to the driving assembly 7 rotate to both sides respectively until the two telescopic rod assemblies 4 close to the driving assembly 7 are rotated to appropriate angles. Then, pull up the two upper telescopic rod assemblies 3, so that each telescopic rod assembly 4 and each telescopic rod 6 gradually extend. Then, pull the two telescopic rod assemblies 4 away from the driving assembly 7 to the side away from the driving assembly 7, so that each telescopic rod assembly 3 gradually extends. Then, adjust the distance between every two adjacent telescopic rods 6, so that each telescopic rod 6 drives the two fixed sleeve assemblies 5 connected to it to slide on the corresponding telescopic rod assembly 3. Finally, place the carton on the surface of the base 1, and use the telescopic rod assemblies 3, telescopic rod assemblies 4, fixed sleeve assemblies 5, and telescopic rods 6 to support both ends of the carton. The area of the rectangular frame formed by the telescopic rod assemblies 3, telescopic rod assemblies 4, fixed sleeve assemblies 5, and telescopic rods 6 can be adjusted according to the carton size, so as to be suitable for placing larger-sized cartons.

[0023] As Figure 1 , Figure 2 shown, the telescopic rod assembly 3 includes a square rod 31. Four square rods 31 are arranged on the top of the base 1. A square block 34 is arranged at one end of each square rod 31. Trapezoidal grooves 32 are formed on the four side wall surfaces of each square rod 31. A trapezoidal rod 33 is movably installed in each trapezoidal groove 32. Each trapezoidal rod 33 is fixedly connected to the adjacent square block 34. It should be noted that by pulling the square block 34, the square block 34 can drive the corresponding four trapezoidal rods 33 to reciprocally slide in the corresponding trapezoidal grooves 32 respectively.

[0024] As Figure 1 , Figure 2As shown, the telescopic rod assembly two 4 includes square tubes 41. There are two square tubes 41 disposed between every two vertically corresponding square rods 31. The bottom end of each square tube 41 is fixedly connected to the adjacent square rod 31 or adjacent square block 34. A lifting rod 42 is movably installed inside each square tube 41. The top end of each lifting rod 42 is fixedly connected to the adjacent square rod 31 or adjacent square block 34. A bolt 43 for squeezing the corresponding lifting rod 42 is threadedly connected to the side wall surface of each square tube 41. It should be noted that by pulling the two square blocks 34 located above and the two square rods 31 located above, each lifting rod 42 can slide up and down inside the corresponding square tube 41. After the square tube 41 needs to stop at the current position, just rotate the corresponding bolt 43 immediately.

[0025] As Figures 1 to 3 shown, the fixed sleeve assembly 5 includes rectangular sleeves 51. A number of rectangular sleeves 51 are sleeved on each square rod 31. A screw one 52 is threadedly connected to the side wall surface of each rectangular sleeve 51. A telescopic rod 6 is fixedly installed between every two vertically corresponding rectangular sleeves 51. It should be noted that if it is necessary to adjust the distance between every two adjacent telescopic rods 6, each telescopic rod 6 will drive the corresponding two rectangular sleeves 51 to move synchronously. Each rectangular sleeve 51 can slide along the corresponding square rod 31 and the four trapezoidal rods 33. When the rectangular sleeve 51 is sleeved on the square rod 31, the corresponding two screws two 53 can be rotated to fix it in the current position, and the corresponding screw one 52 is rotated to make the corresponding screw one 52 squeeze and fix the corresponding trapezoidal rod 33 inside the trapezoidal groove 32.

[0026] As Figures 1 to 3 shown, screws two 53 are respectively threadedly connected to the upper and lower sides of the side wall surface of each rectangular sleeve 51 corresponding to the screw one 52. It should be noted that when the rectangular sleeve 51 is sleeved on the corresponding four trapezoidal rods 33, the corresponding screw one 52 can be rotated to fix it in the current position.

[0027] As Figure 1 、 Figure 2 shown, the driving assembly 7 includes a strip-shaped groove 71. A strip-shaped groove 71 is opened at the top of the base 1. A servo motor one 72 is fixedly installed on the side wall surface of the base 1. The output end of the servo motor one 72 extends into the strip-shaped groove 71 and is fixedly connected to a bidirectional screw rod 73. Two moving blocks 74 are respectively threadedly connected to the two ends of the bidirectional screw rod 73. A servo motor two 75 is fixedly installed on the top of each moving block 74. The output ends of the two servo motor twos 75 are respectively fixedly connected to the adjacent two square tubes 41. It should be noted that when the servo motor one 72 is started, the bidirectional screw rod 73 can reciprocate, so that the two moving blocks 74 approach or move away from each other. The movement of each moving block 74 synchronously drives the servo motor two 75 and the square tube 41 connected to it to move synchronously. Each servo motor two 75 can drive the corresponding square tube 41 to rotate and tilt at a preset angle.

[0028] In summary:

[0029] First, control the driving component 7 according to the size of the carton, so that the two sets of telescopic rod components II 4 close to the driving component 7 move away from or close to each other until the appropriate distance is adjusted between the two sets of telescopic rod components I 3 below. Then, further control the driving component 7 so that the two sets of telescopic rod components II 4 close to the driving component 7 rotate to both sides respectively until the two sets of telescopic rod components II 4 close to the driving component 7 rotate to the appropriate angles respectively. Then, pull up the two sets of telescopic rod components I 3 above, so that each telescopic rod component II 4 and each telescopic rod 6 gradually extend. Then, pull the two sets of telescopic rod components II 4 far from the driving component 7 to the side far from the driving component 7, so that each set of telescopic rod components I 3 gradually extends. Then, adjust the distance between every two adjacent telescopic rods 6, so that each telescopic rod 6 drives the two sets of fixed sleeve components 5 connected to itself to slide on the corresponding telescopic rod component I 3. Finally, place the carton on the surface of the base 1, and use the telescopic rod component I 3, the telescopic rod component II 4, the fixed sleeve component 5, and the telescopic rod 6 to support both ends of the carton. The area of the rectangular frame formed by the telescopic rod component I 3, the telescopic rod component II 4, the fixed sleeve component 5, and the telescopic rod 6 can be adjusted according to the size of the carton, so as to be applicable to the placement of larger-sized cartons.
