Description

Technical Field

[0001] This utility model relates to opening packaging bags, and more particularly to an automatic bag opening device for feeding. Background Technology

[0002] Packaging granular or powdery materials in paper bags or nylon woven bags is a common method for material packaging, transportation, and storage. Currently, when using or processing bagged materials, the bags are often opened or cut manually, and the material is poured onto the conveyor or the receiving device of the processing equipment. This method of opening bags is labor-intensive, time-consuming, and inefficient, especially when a large number of bags need to be loaded. This manual method significantly wastes manpower and reduces the efficiency of the loading operation. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an automatic packing opening device for material packs that has low labor intensity, high efficiency, saves time and effort, saves manpower, and improves the efficiency of material loading operations.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: an automatic packing and unpacking device for feeding, including a frame, a receiving bin for receiving packs conveyed by a conveying device on the frame, a conveying channel for the packs to slide down at the bottom of the receiving bin, a cutter on the conveying channel, the cutter having a blade that extends into the conveying channel to cut the packs, the conveying channel also having a cutting auxiliary device for pushing the packs toward the blade, and a receiving device on the lower side of the conveying channel.

[0005] As a preferred technical solution, the conveying channel includes a slide rail inclined at the bottom of the receiving compartment, the lower end of which is connected to a bag dropping channel through which the bag falls; the cutter is installed on the side wall of the bag dropping channel facing the slide rail, and the bag cutting auxiliary device is located on the other side of the bag dropping channel.

[0006] As a preferred technical solution, the blade of the cutter is concave and curved, and a vertical groove hole for the cutter to pass through is provided on the side wall of the bag drop channel facing the slide. One side of the blade of the cutter extends into the bag drop channel through the vertical groove hole. The upper part of the back side of the cutter is hinged to the frame, and an elastic pushing device is provided between the lower part of the back side of the cutter and the frame.

[0007] As a preferred technical solution, the cutting edge of the cutter is a straight edge or a pointed edge.

[0008] As a preferred technical solution, a plurality of discharge rollers are rotatably arranged on the frame above the receiving device, and the discharge rollers are parallel to each other and spaced apart.

[0009] As a preferred technical solution, a bag-pulling chain is provided on the frame above the discharge roller via several sprockets. One of the sprockets is connected to a bag-pulling drive device. The running direction of the bag-pulling chain is perpendicular to the discharge roller. The inner end of the bag-pulling chain extends to the lower side of the bag-dropping channel. Bag-pulling rubber rods are distributed on the bag-pulling chain. There is a gap between the bag-pulling chain and the discharge roller, and the gap between the inner end of the bag-pulling chain and the discharge roller is greater than the gap between the outer end of the bag-pulling chain and the discharge roller.

[0010] As a preferred technical solution, the bag-cutting auxiliary device includes a pusher roller rotatably mounted on the frame, a roller groove hole on the side wall opposite to the cutter on the bag-dropping channel to allow the pusher roller to extend radially into the bag-dropping channel, an elastic pusher layer on the outer circumferential surface of the pusher roller, and a pusher roller drive device connected to the pusher roller.

[0011] The automatic packing and unpacking device using the above-mentioned technical solution includes a frame. The frame is equipped with a receiving bin for receiving packs conveyed by a conveying device. The bottom of the receiving bin is connected to a conveying channel for the packs to slide down. A cutter is installed on the conveying channel, with blades extending into the channel to cut the packs. The conveying channel also includes a cutting auxiliary device to push the packs towards the blades. A receiving device is located below the conveying channel. In use, this invention conveys packs containing materials to the receiving bin via a conveying device. The bale slides down the conveyor channel at the bottom of the bale receiving compartment and is pushed towards the blade of the cutter by the bale cutting auxiliary device. As the bale slides down the conveyor channel, it is cut open by the blade, thus opening the bale. The opened bale continues to fall in the conveyor channel, while the material inside the bale is poured out through the cut opening and into the receiving device. This achieves automatic bale opening for feeding, eliminating the need for manual opening and emptying. It reduces labor intensity, increases efficiency, saves time and effort, and improves the efficiency of feeding operations, making it especially suitable for feeding large quantities of bales.

Detailed Implementation

[0018] The exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that in the drawings, the same reference numerals are assigned to components that are substantially the same in structure and function, and redundant descriptions of substantially the same components have been omitted to make the description more concise.

[0019] like Figure 1 As shown, the automatic bag-opening device for feeding includes a frame 1. The frame 1 is equipped with a receiving bin 3 for receiving conveyed bags 21 from a conveying device 2. The conveying device 2 can be a common conveying mechanism such as a belt conveyor. The bottom of the receiving bin 3 is connected to a conveying channel for the bags 21 to slide down. The conveying channel can be designed into a cylindrical or elliptical shape depending on the shape of the bags 21. A cutter 7 is provided on the conveying channel, with a blade 71 extending into the conveying channel to cut the bags 21. The conveying channel also has a cutting auxiliary device to push the bags 21 towards the blade 71. A receiving device 6 is provided on the lower side of the conveying channel, which can be a hopper or a conveyor belt.

[0020] like Figure 1 and Figure 2 As shown, the conveying channel includes a slide 4 inclined at the bottom of the receiving compartment 3. The lower end of the slide 4 is connected to a drop channel 5 through which the package 21 falls. The cutter 7 is installed on the side wall of the drop channel 5 facing the slide 4. The cutting auxiliary device is set on the other side of the drop channel 5. The blade 71 of the cutter 7 extends into the drop channel 5 and is set vertically. When the package 21 falls along the slide 4 into the drop channel 5, its front part facing the cutter 7 will accelerate and hit the blade 71 of the vertically set cutter 7 and be cut open. The package 21 continues to fall under its own weight. At the same time, under the action of the cutting auxiliary device, the package 21 is pushed and pressed against the blade 71 of the cutter 7. Thus, during the falling process of the package 21, the package 21 on the side of the cutter 7 is cut open, realizing the opening operation of the package 21.

[0021] like Figure 3As shown, the blade 71 of the cutter 7 is concave and curved. A vertical groove 8 for the cutter 7 to pass through is provided on the side wall of the bag drop channel 5 facing the slide rail 4. One side of the blade 71 of the cutter 7 extends into the bag drop channel 5 through the vertical groove 8. The upper part of one side of the back of the cutter 7 7 is hinged to the frame 1, and an elastic pushing device is provided between the lower part of one side of the back of the cutter 7 7 and the frame 1. The elastic pushing device can be a spring 9 directly connected between the back of the cutter 7 7 7 and the frame 1, or a guide rod 10 can be hinged to the back of the cutter 7 7 7 via a pin. The guide rod 10 slides through a sliding hole 11 provided on the frame 1, and a spring 9 is fitted onto the guide rod 10 between the sliding hole 11 on the frame 1 and the back of the cutter 7 7. Because the upper part of the cutter 7 is hinged to the frame 1, and the lower part is connected to the frame 1 by an elastic pushing device, the lower part of the cutter 7 will extend into the bag drop channel 5 under the push of the elastic pushing device. When the bag 21 falls into the bag drop channel 5 along the slide 4, the front end of the bag 21 will accelerate and hit the blade 71 and be cut. Since the blade 71 is curved, the entire front end of the bag 21 will come into contact with the blade 71 and be cut, increasing the cutting depth of the lower end of the falling bag 21. The opening facilitates the pouring out of the material inside the bag. After that, the material bag 21 falls and the lower part of the cutter 7 is pressed against the spring force of the spring 9 and retracts backward. During the falling process, the material bag 21 is pushed and pressed against the blade 71 of the cutter 7 by the action of the cutting auxiliary device and is cut open, realizing the opening operation of the material bag 21. After the material bag 21 is opened and falls below the cutter 7, the spring 9 pushes the cutter 7 to swing back, so that most of the lower part of the cutter 7 re-extends into the falling channel 5, which facilitates the opening of the next material bag 21.

[0022] Of course, the blade 71 of the cutting blade 7 can also be a straight blade or a pointed blade.

[0023] like Figure 1 and 4 As shown, several material drop rollers 12 are rotatably arranged on the upper side of the receiving device 6 on the frame 1. The material drop rollers 12 are parallel to each other and spaced apart. The parallel and spaced material drop rollers 12 act as a grid to facilitate the material in the material bag 21 to fall into the receiving device 6 after the bag is opened, and also to facilitate the material bag 21 to be dragged away from the outlet of the bag drop channel 5 after the bag is opened.

[0024] like Figure 4As shown, a bag-pulling chain 13 is provided on the frame 1 above the material drop roller 12 via several sprockets 14. One of the sprockets 14 is connected to a bag-pulling drive device 15. The running direction of the bag-pulling chain 13 is perpendicular to the material drop roller 12. The inner end of the bag-pulling chain 13 extends to the lower side of the bag drop channel 5. Bag-pulling rubber rods 16 are distributed on the bag-pulling chain 13. There is a gap between the bag-pulling chain 13 and the material drop roller 12, and the gap between the inner end of the bag-pulling chain 13 and the material drop roller 12 is greater than the gap between the outer end of the bag-pulling chain 13 and the material drop roller 12. Normally, after the package 21 is opened, when it falls below the outlet of the bag drop channel 5, some material remains inside the package 21. This usually requires manual emptying, which is very inconvenient. However, this invention uses a bag-pulling chain 13 with bag-pulling rubber rods 16 distributed on it. The bag-pulling drive device 15 drives the bag-pulling chain 13 to drag the package 21 away from the outlet of the bag drop channel 5 through the bag-pulling rubber rods 16. The discharge roller 12 rotates passively, and the package 21 is dragged on the rotating discharge roller 12. During the dragging process, the remaining material inside the package 21 is emptied. Furthermore, since the gap between the inner end of the bag-pulling chain 13 and the discharge roller 12 is larger than the gap between the outer end and the discharge roller 12, the bag-pulling rubber rods 16 and the opened package 21 are always in contact, which facilitates the emptying of the remaining material inside the package 21 and the cleaning of the package 21 after opening and emptying. Furthermore, the outlet of the bag drop channel 5 can be tilted away from the cutter 7. This makes it easier for the cut side of the bag 21 to fall out of the outlet of the bag drop channel 5 after the bag is opened, so that the material can be poured out easily.

[0025] like Figure 4 As shown, the bag-cutting auxiliary device includes a pusher roller 17 rotatably mounted on a frame 1. A roller groove 18 is provided on the side wall of the bag-dropping channel 5 opposite to the cutter 7, allowing the pusher roller 17 to extend radially into the bag-dropping channel 5. An elastic pusher layer 19 is provided on the outer peripheral surface of the pusher roller 17. The elastic pusher layer 19 can be a rubber layer covering the outer periphery of the pusher roller 17, an inflatable airbag layer, or rubber protrusions distributed on the outer periphery of the pusher roller 17. The pusher roller 17 is driven by a pusher drive device 20. When the pusher drive device 20 drives the pusher roller 17 to rotate, the pusher roller 17 pushes the bag 21 against the blade 71 of the cutter 7 while simultaneously rotating, using the elastic pusher layer 19 to drive the bag 21 to fall into the bag-dropping channel 5, facilitating the smooth opening of the bag 21. The pusher roller 17 and the pusher drive device 20 can be mounted on the frame 1 via a sliding frame and fixed with bolts. This allows the sliding frame to be moved by tightening or loosening the bolts, thereby adjusting the depth of the pusher roller 17 entering the bag drop channel 5 to accommodate bags of different sizes.

[0026] Both the push-bag drive device 20 and the bag-pulling drive device 15 can be driven by electric motors and gearboxes. The gearboxes are connected to the push-bag roller 17 and the bag-pulling chain 13 by belt drive or chain drive.

[0027] like Figure 4 As shown, during operation, the pusher roller 17 and the bag-pulling chain 13 operate under the drive of a motor. The package 21 containing materials is conveyed to the receiving chamber 3 via the conveyor device 2. The package 21 accelerates down through the inclined slide 4 at the bottom of the receiving chamber 3 and falls into the dropping channel 5. The pusher roller 17 rotates and pushes the package 21 towards the cutter 7. During the falling process of the package 21 in the dropping channel 5, the package 21 facing the cutter 7 is cut open, thus opening the package 21. After being opened, the bag 21 continues to fall in the bag drop channel 5, while the material inside the bag 21 is poured out through the cut opening and falls into the receiving device 6. The bag 21 slides down from the bag drop channel 5 onto the drop roller 12. The bag-pulling chain 13 runs and drags the bag 21 away from the outlet of the bag drop channel 5 through the bag-pulling rubber rod 16. The bag 21 is dragged on the rotating drop roller 12 while the remaining material is poured out. After the material is poured out, the bag 21 is dragged away from the drop roller 12 by the bag-pulling rubber rod 16 and then cleaned.
