[0020] The utility model is further described below in conjunction with embodiments.

[0021] Example: Refer to Figures 1 to 3 A convenient carton detection mechanism includes a base 1, support columns 2 are symmetrically fixedly arranged at both ends of the base 1, a sliding mechanism 3 is arranged inside the support column 2, a pressure measuring mechanism 5 is fixedly connected to the sliding mechanism 3, a control system 4 is fixedly arranged on the outer side of the support column 2, a positioning mechanism 6 for positioning the carton is arranged at the upper end of the base 1, and a sliding wheel 7 is fixedly arranged at the lower end of the base 1. The carton is positioned by the positioning mechanism 6, and then the pressure measuring mechanism 5 is driven to slide up and down by the sliding mechanism 3 to measure the pressure of the carton.

[0022] Further, refer to Figure 1 The specific structure of the sliding mechanism 3 is described as follows:

[0023] The sliding mechanism 3 includes two limit grooves 31, and the two limit grooves 31 are both opened in the support column 2. Sliding rods 32 are rotatably arranged in the two limit grooves 31. The two sliding rods 32 are sleeved and connected with sliding plates 34. A motor 33 is fixedly arranged on the upper end of the support column 2. The output end of the motor 33 passes through the support column 2 and is fixedly connected to the top end of one of the sliding rods 32. By starting the motor 33, the sliding rod 32 drives the sliding plate 34 to slide up and down, and the sliding plate 34 drives the pressure measuring mechanism 5 to perform pressure measurement on the carton.

[0024] Further, refer to Figure 1 The specific structure of the positioning mechanism 6 is described as follows:

[0025] The positioning mechanism 6 includes two bidirectional reciprocating screw rods 64, which are arranged in the base 1 in a three-dimensional staggered rotation. Both ends of the bidirectional reciprocating screw rods 64 are sleeved with nut seats 63, and the upper ends of the nut seats 63 are fixedly connected with connecting blocks 62. The upper end of the base 1 is provided with sliding grooves 65 corresponding to the positions of the two bidirectional reciprocating screw rods 64. The connecting block 62 is arranged in the sliding groove 65, and the other end of the connecting block 62 is fixedly connected with a sliding block 61. The connecting block 62 and the sliding block 61 are an integrally formed structure. The one-piece structure is a T-shaped structure. When the carton pressure is measured, the carton is first placed on the base 1, and then the two bidirectional reciprocating screws 64 are rotated through the control system 4. The bidirectional reciprocating screws 64 drive the nut seat 63 to slide back and forth. The nut seat 63 drives the sliding block 61 to slide back and forth on the base 1 through the connecting block 62 to clamp the carton on the base 1 to a fixed position. Then the sliding block 61 slides to the two ends of the bidirectional reciprocating screw 64, and then the sliding plate 34 drives the pressure measuring mechanism 5 to measure the pressure of the carton.

The two support plates 52 are fixedly connected to the pressure plate 54 through the fixing rods 53, so that the pressure plate 54 is kept in a horizontal state. When the carton is pressure tested, the pressure on each contact surface is balanced. When the sliding plate 34 drives the pressure plate 54 to slide up and down, so that the pressure plate 54 contacts the carton, the pressure sensor 51 enters the detection state, so that the sliding plate 34 drives the pressure plate 54 to perform pressure measurement on the carton.

[0028] Furthermore, the control system 4 is electrically connected to the motor 33, two bidirectional reciprocating screws 64, and the pressure sensor 51. Through the control of the control system 4, the entire carton detection process can be carried out normally and accurately.

[0030] When measuring the pressure of a carton, first place the carton on the base 1, and cooperate with the control system 4 with the two bidirectional reciprocating screws 64, the motor 33, and the pressure sensor 51 to make the two bidirectional reciprocating screws 64 rotate, and the bidirectional reciprocating screws 64 drive the nut seat 63 to slide back and forth, and the nut seat 63 drives the sliding block 61 to slide back and forth on the base 1 through the connecting block 62 to clamp the carton on the base 1 to a fixed position, and then the sliding block 61 slides to the two ends of the bidirectional reciprocating screw 64.

[0031] Furthermore, the motor 33 drives the sliding rod 32 to rotate, the sliding rod 32 drives the sliding plate 34 to slide up and down, and the sliding plate 34 drives the pressure plate 54 to slide up and down.
