[0044] Example 1

[0045] See Figure 1-9 As shown, the box opening mechanism includes a mounting seat 1 and a pick-up and delivery platform 2 for placing a box body 6, the mounting seat 1 is connected to the pick-up and delivery platform 2, and includes: a driving mechanism 3, a guiding mechanism 4 and a box opening frame 5, the driving mechanism 3 is mounted on the mounting seat 1, the output end of the driving mechanism 3 is connected to the box opening frame 5, and is used to push the box opening frame 5 to slide up and down on the pick-up and delivery platform 2, the guiding mechanism 4 is mounted on the pick-up and delivery platform 2, and the top of the box opening frame 5 passes through the guiding mechanism 4. The setting of the guiding mechanism 4 reduces the force required for the box opening frame 5 to slide up and down, and at the same time reduces the force on the output shaft of the driving mechanism 3, reduces the wear of the driving mechanism 3, and has a simple structure, is easy to use, and has strong stability.

[0046] In a further specific embodiment, the box opening frame 5 includes a box opening member 51, a support member 52 and a mounting plate 53, wherein the box opening member 51 and the support member 52 are respectively mounted on the mounting plate 53. It should be noted that the bottom of the box opening member 51 of the utility model is fixedly mounted on the mounting plate 53, and the bottom of the support member 52 is slidably mounted on the mounting plate 53. The box opening member 51 and the support member 52 respectively penetrate the guide mechanism 4 and the pick-up and delivery platform 2. When the driving mechanism 3 drives the box opening frame 5 to slide up and down on the pick-up and delivery platform 2, the box opening member 51 penetrates the pick-up and delivery platform 2 and extends into the box body 6 to lift up the box cover 61 and flip it over to open it, and the support member 52 penetrates the pick-up and delivery platform 2 and extends into the box body 6 to lift up the product 7 located in the box body 6. Under the action of the guide mechanism 4, the box opening member 51 and the support member 52 are respectively guided to reduce the force on the driving mechanism 3.

[0047] The existing box opening rack 5 has a high cost, a small contact surface between the box opening rack 5 and the pizza, and an uneven force area. In a further specific embodiment, the tops of the support member 52 and the box opening member 51 are respectively provided with support sheets 54. By providing the support sheets 54, the contact surface between the product 7 and the box opening rack 5 is increased, so that the friction between the product 7 and the box opening rack 5 is greater, and the product 7 is more stable when it is lifted up and is not easy to slide.

[0048] In a further specific embodiment, the support sheet 54 is circular. The pick-up and delivery platform 2 is provided with a limiting groove 21 for accommodating the support sheet 54. In other specific embodiments, the support sheet 54 may also be triangular, rectangular or polygonal, and the corresponding pick-up and delivery platform 2 may also be provided with a limiting groove 21 corresponding to the shape of the support sheet 54. By setting the limiting groove 21, when the box opening member 51 and the support member 52 slide downward to the lowest point, the support sheet 54 can be accommodated in the limiting groove 21, so as to prevent the support sheet 54 from being exposed from the pick-up and delivery platform 2 to block the shipment of the product 7, and the structure is simple and practical.

[0049] In a further specific embodiment, the guide mechanism 4 includes a first guide bearing group 41 and a second guide bearing group 42, the first guide bearing group 41 is installed on the pick-up and delivery platform 2, the tops of the box opening member 51 and the support member 52 respectively penetrate the first guide bearing group 41, the second guide bearing group 42 is installed on the mounting plate 53, and the bottom of the support member 52 penetrates the second guide bearing group 42. The tops of the box opening member 51 and the support member 52 are guided by the first guide bearing group 41, and the bottom of the support member 52 is guided by the second guide bearing group 42. The force required for the box opening frame 5 to slide up and down is further reduced, and the force on the output shaft of the driving mechanism 3 is reduced, and the wear of the driving mechanism 3 is reduced, and the structure is simple, easy to use, and stable.

[0050] In a further specific embodiment, the driving mechanism 3 is a linear motor, which is mounted on the mounting seat 1, and the output end of the linear motor is connected to the bottom of the mounting plate 53. This arrangement is simple in structure and highly practical.

[0051] In a further specific embodiment, the support member 52 is sleeved with an elastic member 55, the first end of the elastic member 55 abuts against the bottom of the support member 52, and the second end of the elastic member 55 abuts against the second guide bearing group 42. The support member 52 includes a first support portion 521 and a second support portion 522, the diameter of the first support portion 521 is larger than the diameter of the second support portion 522, the first support portion 521 is slidably mounted on the first guide bearing group 41, and the second support portion 522 is slidably mounted on the second guide bearing group 42. It should be noted that the length of the box opening member 51 is longer than the length of the first support portion 521, the length of the box opening member 51 is shorter than the length of the support member 52, and both the support member 52 and the box opening member 51 are cylindrical.

[0052] In the prior art, the box opening member 51 needs to enter the box body 6 before the support member 52, lift up the box cover 61 to open it, and then the support member 52 enters the box body 6 to lift up the product 7. This arrangement is to prevent the product 7 from directly contacting the box cover 61. The tightness of the box cover 61 covering the box body 6 may cause the product 7 to be pushed by the box cover 61 and fall. Therefore, in the prior art, the length of the box opening member 51 is longer than the length of the support member 52. It should be noted that the overall length of the support member 52 of the utility model is longer than the length of the box opening member 51. At the same time, because the bottom of the box opening member 51 of the utility model is fixedly mounted on the mounting plate 53, and the bottom of the support member 52 is slidably mounted on the mounting plate 53, the mounting plate 53 will directly drive the box opening member 51 to rise and fall when it rises, and through the setting of the elastic member 55, the support member 52 is always subjected to a force downward away from the mounting plate 53, so the box opening member 51 will extend into the box body 6 first to open the box cover 61. When the mounting plate 53 drives the second guide bearing group 42 to rise to the first support part 521, the diameter of the first support part 521 is larger than the inner diameter of the second guide bearing group 42. The second guide bearing group 42 limits the first support part 521, thereby driving the first support part 521 to rise, thereby achieving the goal that the box opening member 51 enters the box body 6 before the support member 52 to open the box cover 61.

[0053] After the box cover 61 is opened and the product 7 is supported, when it is necessary to return to the origin, the driving mechanism 3 drives the mounting plate 53 to descend, and the supporting piece 54 on the supporting member 52 first enters the limiting groove 21, and the second guide bearing group 42 gradually moves away from the first supporting part 521 until the supporting piece 54 on the box opening member 51 enters the limiting groove 21 and returns to the origin.

[0054] It should be noted that the elastic member 55 of the utility model is a spring, and when the drive mechanism 3 drives the mounting plate 53 to gradually descend, the second guide bearing group 42 always fits the first support portion 521 until the support sheet 54 of the support member 52 enters the limiting groove 21, and the first support portion 521 can no longer descend. At this time, the second guide bearing group 42 gradually moves away from the first support portion 521, and the mounting plate 53 gradually approaches the bottom of the second support portion 522, compressing the spring until the support sheet 54 of the box opening member 51 also enters the limiting groove 21.

[0055] Example 2

[0056] The difference between this embodiment and the embodiment is only that: "The support member 52 includes a first support portion 521 and a second support portion 522, a limiting block is provided at the connection between the first support portion 521 and the second support portion 522, the first support portion 521 is slidably mounted on the first guide bearing group 41, and the second support portion 522 is slidably mounted on the second guide bearing group 42." Other details are not repeated here. This embodiment limits the position of the second guide bearing group 42 by setting a limiting block. When the second guide bearing group 42 contacts the limiting block when rising, the limiting block can push the first support portion 521 to rise. When descending, after the support sheet 54 of the support member 52 enters the limiting groove 21, the second guide bearing group 42 gradually moves away from the limiting block and gradually approaches the bottom of the second support portion 522, compressing the spring until the support sheet 54 of the box opening member 51 also enters the limiting groove 21.
