Description

Technical Field

[0001] The present application relates to the technical field of packaging bag conveying, and in particular to a high-speed automatic small bag rotating device. Background Art

[0002] In automated production lines, powder products such as coffee powder and pharmaceutical granules are usually filled into small packaging bags and sold in single-serving doses. These packaging bags need to be smoothly and efficiently stood up on the conveyor belt from a flat position so that they can be neatly placed in packaging boxes later. However, existing small packaging bags are mostly adjusted from a flat position to a sideways position using a robotic arm to assist in flipping. This solution is not only inefficient and costly, but also because the small packaging bags are light in weight, the speed is too fast during the sideways process and the packaging bags may fly out of the conveyor belt, which not only affects production efficiency, but also causes material waste and equipment damage. Summary of the invention

[0049] The material guiding mechanism 2 is used to guide the small packaging bag into the material receiving mechanism 3 in a flat position, and the rotating and pulling mechanism 5 is used to support the small packaging bag. When the rotating and pulling mechanism 5 moves laterally relative to the material receiving mechanism 3, the material receiving mechanism 3 pushes the small packaging bag to slide from the gap of the rotating and pulling mechanism 5, and slides through the pressing side flipping mechanism 4 to the rotating limit mechanism 6 and the rotating support mechanism 7;

[0050] The top-pressing and side-turning mechanism 4 is used to tilt and press the small packaging bag to turn the small packaging bag over and stand it sideways; the turning and standing limiting mechanism 6 is used to support the side wall of the small packaging bag when it is standing sideways, the turning and standing supporting mechanism 7 is used to support the bottom side edge of the small packaging bag when it is standing sideways, and the packaging bag pushing mechanism 8 is used to push the side-standing small packaging bag to move in the longitudinal direction away from the material guiding mechanism 2.

[0051] The present application guides the small packaging bag into the material receiving mechanism 3 in a lying position through the material guiding mechanism 2, supports the small packaging bag through the rotating and pulling mechanism 5, and when the rotating and pulling mechanism 5 moves horizontally relative to the material receiving mechanism 3, the material receiving mechanism 3 presses and pushes the small packaging bag to slide from the gap of the rotating and pulling mechanism 5, and slides through the pressing side flipping mechanism 4 to the rotating limiting mechanism 6 and the rotating supporting mechanism 7; the pressing side flipping mechanism 4 tilts and presses the small packaging bag to flip the small packaging bag from a lying state to a side standing state, the rotating limiting mechanism 6 is used to support the side wall of the small packaging bag when it is side standing, the rotating supporting mechanism 7 supports the bottom side edge of the small packaging bag when it is side standing, and the packaging bag pushing mechanism 8 is used to push the side standing small packaging bag to move in the longitudinal direction away from the material guiding mechanism 2; during the conveying process, the present application can realize the smooth and efficient side standing of the lying powder packaging bag, avoids the problem of the small packaging bag flying out of the conveyor belt due to excessive speed, improves production efficiency, and reduces the risk of material waste and equipment damage.

[0052] The present application relies on the small package bags to slide down due to their own gravity, and uses the top-pressure side flipping and standing mechanism 4 to guide the small package bags to flip to a sideways state. There is no need for a mechanical arm or other external force to assist in pushing the small package bags to flip sideways directly, which further reduces the risk of the small package bags flying off the conveyor belt due to being too light or too fast.

[0054] The present application sets a material receiving limit through hole 31 which penetrates the upper and lower surfaces of the material receiving mechanism 3 on the material receiving mechanism 3 to limit the movement of the small packaging bag and ensure the accurate positioning of the small packaging bag in the material receiving mechanism 3; the material receiving guide port 32 located on the side wall of the material receiving mechanism 3 is used to connect the material receiving limit through hole 31 and the material guiding mechanism 2, so that the small packaging bag can smoothly enter the material receiving limit through hole 31 from the material guiding mechanism 2, thereby improving the stability and reliability of the small packaging bag during the transmission process, thereby further improving the working efficiency and product quality of the entire high-speed small bag automatic rotation device.

[0055] Furthermore, if Figures 2 to 4 As shown, the rotating and pulling mechanism 5 includes a rotating and pulling frame 51, a packaging bag support plate 52 arranged on the rotating and pulling frame 51 and spaced along the length direction of the rotating and pulling frame 51, and a push-pull driving assembly 53 arranged on the top-pressing side flipping and standing mechanism 4 and connected to the rotating and pulling frame 51. A rotating and sliding through hole 54 for allowing small packaging bags to slide from the material receiving mechanism 3 to the top-pressing side flipping and standing mechanism 4 is provided between two adjacent packaging bag support plates 52;

[0056] The rotating and pulling frame 51 is laterally inserted between the material receiving mechanism 3 and the top pressure side flipping and standing mechanism 4; the packaging bag support plate 52 is aligned with the material receiving limit through hole 31. When the small packaging bag slides onto the packaging bag support plate 52, the push-pull drive assembly 53 drives the rotating and pulling frame 51 to pull laterally, so that the rotating and sliding through hole 54 is aligned with the material receiving limit through hole 31, and the inner side wall of the material receiving limit through hole 31 pushes the small packaging bag to slide from the rotating and sliding through hole 54 to the top pressure side flipping and standing mechanism 4.

[0057] The present application provides packaging bag support plates 52 spaced along the length direction of the rotating and pulling frame 51 on the rotating and pulling frame 51, and provides a rotating and sliding through hole 54 between two adjacent packaging bag support plates 52, so that the small packaging bag can stably slide to the top pressure side flipping and standing mechanism 4; the packaging bag support plate 52 is aligned with the material receiving limit through hole 31, and when the small packaging bag slides into the material receiving limit through hole 31, the packaging bag support plate 52 is used to support the small packaging bag, and the push-pull drive component 53 drives the rotating and pulling frame 51 to pull horizontally, so that the rotating and sliding through hole 54 is aligned with the material receiving limit through hole 31, thereby realizing a smooth transition of the small packaging bag from the material receiving mechanism 3 to the top pressure side flipping and standing mechanism 4; this design not only improves the stability and reliability of the small packaging bag side standing process, but also can effectively avoid the risk of the small packaging bag flying out of the conveyor belt during the side standing process, thereby efficiently completing the side standing and flipping process of the small packaging bag, and improving the efficiency and stability of the automated production line.

[0059] The present application realizes the stable assembly of the push-pull drive assembly 53 and the top-pressing side flipping stand mechanism 4 by connecting the fixed plate 531 with the end of the top-pressing side flipping stand mechanism 4, connecting the push-pull drive component 532 with the fixed plate 531, and connecting the eccentric shaft component 533 with the output end of the push-pull drive component 532; one end of the push-pull rod 534 is connected to the bearing of the eccentric shaft component 533, and the other end is connected to the bearing at the end of the rotating and pulling frame 51, so that the push-pull rod 534 can drive the rotating and pulling frame 51 to move horizontally through the transmission of the eccentric shaft component 533 under the drive of the push-pull drive component 532; this design structure is simple and compact, can provide stable push-pull force, ensure the reliable operation of the rotating and pulling mechanism 5, and make the movement of the small packaging bag in the side-standing process more stable and accurate, thereby further improving the working efficiency and product quality of the high-speed small bag automatic rotating device;
