Description

Technical Field

[0001] This utility model relates to the technical field of bag-loading devices, specifically an automatic bag-loading device for granular materials. Background Technology

[0002] The automatic bagging device for granular materials is a modern piece of equipment that integrates mechanical, electronic, and automated control technologies. It is designed specifically for granular materials (such as granular products in the food, chemical, agricultural, and pharmaceutical industries) and can automatically pick up and open bags.

[0003] Existing bagging devices of this type generally require a long production line structure, which results in a long production line and a large overall footprint. Many manufacturers find it difficult to deploy such devices due to space constraints. Therefore, an improved automatic bagging device for granular materials is needed to address this issue. Utility Model Content

[0004] The purpose of this invention is to provide an automatic bagging device for granular materials to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic bagging device for granular materials, comprising a functional compartment, wherein a bag-loading mechanism for picking up and supporting bags is provided inside the functional compartment. The bag-loading mechanism includes a support, a first rotary motor, a first telescopic cylinder, a first suction cup assembly, a second rotary motor, a second telescopic cylinder, a second suction cup assembly, a third telescopic cylinder, and a third suction cup assembly. A support is fixedly installed on one side inside the functional compartment, and a first rotary motor is fixedly installed on the surface of the support. A first telescopic cylinder is fixedly installed at the power output shaft end of the first rotary motor, and a first suction cup assembly is fixedly installed at the movable end of the first telescopic cylinder. A second rotary motor is installed on one side of the support inside the functional compartment, and a second telescopic cylinder is fixedly installed at the power output shaft end of the second rotary motor. A second suction cup assembly is fixedly installed at the movable end of the second telescopic cylinder. A third telescopic cylinder is fixedly installed on one side of the second rotary motor inside the functional compartment, and a third suction cup assembly is fixedly installed at the movable end of the third telescopic cylinder.

[0006] Preferably, the functional compartment is equipped with a conveyor belt, which can transport a bag of granules to the next station for sealing or other operations; and since the granules filled by this device are such as rice, the bag is not easy to tip over when it falls onto the upper end of the conveyor belt after the bag contains rice.

[0007] Preferably, baffles are provided on both sides of the upper end of the conveyor belt inside the functional compartment, which can limit the position of the packaging bags.

[0008] Preferably, a storage compartment is fixedly provided on one side of the upper end of the functional compartment. The storage compartment has a notch at the lower end. The storage compartment of this device can store multiple packaging bags. The notch at the lower end of the storage compartment is smaller than the packaging bag, so that the packaging bag cannot pass through the notch under the action of gravity. It can only pass through when it is attracted and pulled downward by the first suction cup assembly.

[0009] Preferably, a filling port is provided on one side of the upper end of the functional compartment, through which particulate matter can be conveniently filled into the packaging bag.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model has high space utilization: it integrates bag picking, transfer, bag supporting and filling functions into one unit, optimizes the internal layout of the functional compartment, and simplifies the overall volume to meet the needs of compact production line transformation.

[0018] Please see Figure 1-4This utility model provides a technical solution: an automatic bagging device for granular materials, including a functional compartment 1, which integrates a bag-picking and bag-opening integrated bag-loading mechanism. This device realizes automatic picking, placing, unfolding, and conveying of packaging bags through a multi-axis cooperative mechanical structure, and its specific structure is as follows:

[0019] The upper bag mechanism adopts a three-dimensional spatial positioning design, including:

[0020] Bag-grabbing assembly: A bracket 15 is fixed to the side wall of the functional compartment 1, on which a first rotary motor 2 is installed. The power output end is connected to a first telescopic cylinder 3, and the end is equipped with a first suction cup assembly 4. The packaging bag is adsorbed and grasped through a rotary-telescopic compound motion.

[0021] Transfer assembly: The independently set second rotary motor 5 drives the second telescopic cylinder 6, and the end second suction cup assembly 7 is responsible for the transfer of the packaging bag space.

[0022] Bag support assembly: The fixed third telescopic cylinder 8 is equipped with the third suction cup assembly 9, which works in conjunction with the second suction cup assembly 7 to expand the opening of the packaging bag.

[0023] Material handling system

[0024] Transmission Unit: The bottom of Functional Compartment 1 is equipped with a conveyor belt 10, which adopts an anti-slip toothed belt structure to ensure that the packaging bags loaded with rice and other granular materials are stably transported to the sealing station.

[0025] Guiding mechanism: Adjustable baffles 11 are configured on both sides of the conveyor belt 10, and the spacing can be adjusted from 50-300mm through the bolt locking mechanism to adapt to different sizes of packaging bags.

[0026] Bag storage device: The top of the functional compartment 1 is equipped with a storage compartment 12, which adopts a gravity feeding design. The bottom notch 13 is 15%-20% smaller than the packaging bag. It works in conjunction with the negative pressure adsorption of the first suction cup assembly 4 to achieve single bag separation.

[0027] Filling interface: Functional compartment 1 has a pre-set DN80 standard filling port 14 at the top, equipped with a dust cover and quick-change connector, which can be compatible with filling of granular materials of different particle sizes.

[0028] Working principle bag removal stage: The first rotary motor 2 drives the first suction cup assembly 4 to rotate to the bottom of the storage chamber 12. The first telescopic cylinder 3 extends to make the suction cup contact the surface of the packaging bag. The vacuum generator starts to complete the adsorption. The cylinder retracts to achieve single bag separation.

[0029] Transfer stage: The first rotary motor 2 rotates 120° in the opposite direction to transfer the packaging bag to the docking position of the second suction cup assembly 7. The second suction cup assembly 7 starts vacuum adsorption, and the first suction cup assembly 4 releases, completing the handover of the packaging bag.

[0030] Bag opening stage: The second rotary motor 5 drives the packaging bag to rotate 90° to the front of the third suction cup assembly 9. The second and third telescopic cylinders extend synchronously, and the opening of the packaging bag is expanded through the differential motion of the two suction cups. The opening diameter can reach 400mm.

[0031] Filling and conveying: After the granules are quantitatively injected through the filling port 14, the packaging bag falls naturally to the conveyor belt 10 and is conveyed in a straight line to the subsequent station under the constraint of the baffle 11.
