Description

Technical Field

[0001] This utility model relates to the field of packaging box opening, and in particular to an automatic box opening mechanism. Background Technology

[0002] In modern packaging production lines, manual box opening has many limitations: First, manual operation is inefficient, with a single worker only able to complete 5-8 box opening actions per minute, which is insufficient to meet the high-speed requirements of modern production lines; second, the force applied during manual box opening is difficult to control precisely, which can easily cause the packaging box to deform or break; and third, prolonged repetitive operation can easily lead to worker fatigue. Therefore, automated box opening is a key link in improving packaging efficiency.

[0003] However, existing automatic box opening equipment generally suffers from problems such as complex structure and poor adaptability. Most equipment can only handle packaging boxes of a single size. When changing products, it is necessary to readjust the equipment. Moreover, the accuracy of the readjustment cannot be guaranteed, which can easily lead to insufficient precision in the box opening action. In addition, the suction cup is often unstable or the box is not fully opened, which affects the stability of the box opening and the efficiency of the box opening and packaging.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] This utility model provides, for example Figure 1-4 An automatic box opening mechanism is shown, including a mounting plate 1, a lifting mechanism 2, a moving plate 3, a transmission mechanism 4, a drive mechanism 5, and suction cups 6. The lifting mechanism 2 is mounted on the front of the mounting plate 1, and the moving plate 3 is mounted on the front of the lifting mechanism 2. The moving plate 3 is slidably connected to the surface of the mounting plate 1. The transmission mechanism 4 is mounted on the front of the moving plate 3, and the drive mechanism 5 is mounted on one side of the transmission mechanism 4. The drive mechanism 5 is used to drive the opening and closing of the transmission mechanism 4. Multiple suction cups 6 are mounted on the transmission mechanism 4 and are used for adsorption on the sides of the box.

[0036] The lifting mechanism 2 includes a slide 21, a lifting cylinder 22, a positioning block 23, and a slide 24. The slide 21 is fixed to one side of the mounting plate 1, and the lifting cylinder 22 is fixed to the other side of the mounting plate 1. The positioning block 23 is fixedly connected to the telescopic end of the lifting cylinder 22. The lifting cylinder 22 is electrically connected to an external power supply through an external switch. The slide 24 slides longitudinally on the front side of the slide 21 and is fixedly connected to the back side of the moving plate 3. The positioning block 23 is fixed to the back side of the moving plate 3. The lifting cylinder 22 is used for the longitudinal sliding of the moving plate 3. Driven by the lifting cylinder 22, the positioning block 23 can drive the moving plate 3 to move up and down, so that the slide 24 can move on the surface of the slide 21, thereby improving the stability of the position of the moving plate 3.

[0037] In addition, the transmission mechanism 4 includes a rotating shaft 41, a first transmission gear 42, a second transmission gear 43, and multiple supports 44. The multiple rotating shafts 41 are rotatably connected to the top two sides of the movable plate 3 through bearings. The first transmission gear 42 is fixed to one end of one of the rotating shafts 41, and the second transmission gear 43 is fixed to one end of the other rotating shaft 41. The opposite sides of the first transmission gear 42 and the second transmission gear 43 are meshed together. The multiple supports 44 are fixed horizontally opposite to the front of the first transmission gear 42 and the front of the second transmission gear 43, and the two supports 44 are fixed to the opposite ends of the front of the first transmission gear 42 and the second transmission gear 43, so that when the first transmission gear 42 and the second transmission gear 43 rotate relative to each other, the two supports 44 move in an opening and closing motion. The multiple suction cups 6 are fixed in a relative state between the multiple supports 44. The suction cups 6 can adhere to the side of the box, which facilitates the opening and closing of the side of the box by the opening and closing motion of the supports 44.

[0038] Furthermore, the drive mechanism 5 is installed between the second transmission gear 43 and the moving plate 3. The drive mechanism 5 includes a drive cylinder 51 and a rotating pin 52. The drive cylinder 51 is fixed to one end of the moving plate 3 and is electrically connected to an external power source through an external switch. The rotating pin 52 is rotatably inserted through one side of the second transmission gear 43 via a bearing and is also rotatably inserted through the telescopic end of the drive cylinder 51 via a bearing. In use, the lifting cylinder 22 drives the moving plate 3 to move the transmission mechanism 4, the drive mechanism 5, and the suction cup 6, so that the bracket 44 can be located on both sides of the box. The drive cylinder 51 is driven, causing the telescopic end of the drive cylinder 51 to retract, which drives the first transmission gear 42 and the second transmission gear 43 to mesh and rotate, so that the suction cup 6 on the bracket 44 can suck down to the side of the box. The drive cylinder 51 is driven in the opposite direction, causing the telescopic end of the drive cylinder 51 to extend, thus opening the box, facilitating the loading of materials, reducing labor costs, and improving the efficiency of opening the box.
