Description

Technical Field

[0001] The utility model relates to the technical field of clamping devices, and more specifically to a carton packaging clamping device. Background Art

[0002] Carton packaging refers to the packaging of products in paper boxes in order to protect the products, facilitate storage and transportation, and promote sales during the circulation process. In the carton packaging process, clamping devices are often used to clamp and fix the cartons to facilitate subsequent work.

[0003] For example, a carton packaging clamping device proposed in announcement number CN220114937U includes a conveyor platform, support legs are sequentially installed on the lower surface of the conveyor platform, a cross bar is fixedly installed between the front and rear support legs near the lower end, a base is fixedly installed on the lower surface of the support leg, rollers are movably installed in the middle of the conveyor platform in sequence, vertical bars are fixedly installed on the front and rear surfaces of the conveyor platform near one end, a clamping structure is arranged on the upper end of the vertical bar, a protective structure is arranged in the middle, the clamping structure includes a motor, a bearing, a spiral rod, a slider, a cross beam, a vertical plate, a rectangular groove, and a fixed plate, and a cross beam is fixedly installed on the upper end of the vertical bar. The carton packaging clamping device described in the utility model can avoid deformation of the carton due to excessive clamping force when the clamping device clamps the carton, and can also protect the carton during the clamping process to avoid damage to the carton due to friction, which causes increased carton loss.

[0004] The above patent has the following defects during use:

[0005] When clamping cartons of different sizes, since the position of the clamp is fixed, it is not convenient to adjust the position according to the size of the carton, resulting in it not being in a suitable clamping position. For example, when clamping a small carton of small volume, it is easy for a part of the clamping surface of the clamp to contact the carton surface, while the other part is empty, thus affecting the clamping effect. Moreover, when clamping a large carton of large volume, the size of the clamp is fixed, and the contact area with the large carton surface is small during clamping, which easily makes the clamping force concentrated on a single point position on the large carton surface, causing the force at this position to be too concentrated and deformed. Therefore, it is urgent to improve the technology of the clamping device to improve this equipment.

[0006] To this end, the utility model provides a carton packaging clamping device. Utility Model Content

[0029] Example:

[0030] See also Figure 1-5A carton packaging clamping device comprises a conveying platform 1, a pair of supporting rods 2 are fixedly connected to the outer end of the conveying platform 1, and a rectangular frame 3 is fixedly connected between the upper ends of the pair of supporting rods 2, a pair of movable rods 6 are arranged on the lower side of the rectangular frame 3, and a synchronous moving mechanism 5 is installed between the pair of movable rods 6 and the rectangular frame 3, an industrial visual inspection camera 4 is installed on the outer end of the rectangular frame 3, an electric slide rail 7 is installed at the lower end of the pair of movable rods 6, and the electric slide rail 7 is electrically connected to the industrial visual inspection camera 4, a pair of electric slide rails 7 are sleeved with driving sliders 8, and the driving sliders 8 are slidably connected to them, a pair of first clamping plates 9 are arranged between the pair of driving sliders 8, and a second clamping plate 11 is arranged on the outer side of the pair of first clamping plates 9, a buffer mechanism 12 is installed on the end of the first clamping plate 9 and the second clamping plate 11 close to the driving slider 8, and a rubber pad 10 is bonded to the end of the first clamping plate 9 and the second clamping plate 11 away from the driving slider 8, and a push-pull docking mechanism 13 is installed between the second clamping plate 11 and the electric slide rail 7.

[0031] During the use of this solution, when multiple cartons are transported on the conveyor 1 in turn, the industrial visual inspection camera 4 can identify and measure the size of the cartons with the help of machine vision technology, and feed back to the telescopic cylinder 1304 and the electric slide rail 7 in the push-pull docking mechanism 13 and the rotating motor 502 in the synchronous moving mechanism 5 respectively. If the carton is a small volume carton after identification and measurement, the electric slide rail 7 drives the driving slider 8 to slide up and down, so that it drives the first clamping plate 9 to move up and down, and adjusts the position accordingly according to the height of the carton, so that the first clamping plate 9 is adjusted to a suitable position. The clamping position is set to facilitate subsequent clamping to avoid partial clamping. Then, the rotating motor 502 drives the bidirectional screw 501 to rotate, so that it drives a pair of hollow sleeve blocks 503 to move toward each other, prompting a pair of movable rods 6 to move toward each other along the transverse through groove 504, and drives a pair of electric slide rails 7 and a driving slider 8 to move toward each other, so that it drives a pair of first clamping plates 9 and rubber pads 10 to move toward each other and contact and clamp with the outer end of the carton.

If the carton is a large-volume carton after identification and measurement, it is difficult for the first clamping plate 9 to maintain sufficient contact with it, and a pair of telescopic cylinders 1304 are contracted to pull the U-shaped rod 1305 to move slowly in the direction of the connecting slide plate 1301, driving the two pairs of cylinders 1201 and the piston rod 1202 to move slowly toward the outside of the cylindrical through groove 1303, and driving the second clamping plate 11 to move slowly toward the first clamping plate 9, until it is fitted together with the first clamping plate 9 to form a large clamping plate, and then the electric slide rail 7 drives the first clamping plate 9 and the second clamping plate 11 to adjust their positions through the driving slider 8, and then the synchronous moving mechanism 5 drives a pair of first clamping plates 9 and the second clamping plates 11 to move towards each other, and with the assistance of the buffer mechanism 12 and the rubber pad 10, the carton is clamped to maintain a sufficient contact surface with the large carton surface, so as to avoid the contact surface being too small and causing the force to be concentrated at a single position on the large carton surface, thereby avoiding deformation of the force-bearing position of the large carton surface, thereby ensuring its clamping effect.

A pair of transverse through grooves 504 are opened at the lower end of the rectangular frame 3, and the upper ends of a pair of movable rods 6 pass through the transverse through grooves 504 and are fixedly connected to the hollow sleeve blocks 503.

[0033] During use of this solution, the rotating motor 502 drives the bidirectional screw 501 to rotate, which drives a pair of hollow sleeves 503 to move toward each other with the assistance of a pair of internal threads, prompting a pair of movable rods 6 to move toward each other along the transverse through grooves 504, and driving a pair of electric slide rails 7 and a driving slider 8 to move toward each other, which drives a pair of first clamping plates 9 and second clamping plates 11 and rubber pads 10 to move toward each other and contact and clamp with the outer end of the carton.

[0034] See also Figure 2 A pair of external threads are provided at the outer end of the bidirectional screw 501, and the directions of the pair of external threads are opposite. The inner walls of the pair of hollow sleeves 503 are provided with internal threads, and the pair of hollow sleeves 503 are respectively threadedly connected with the pair of external threads on the bidirectional screw 501 through a pair of internal threads.
