Description

Technical Field

[0001] The present invention relates to the technical field of feeding equipment, and specifically, to a high-speed unpacking and feeding device. Background Art

[0002] The gunny soft bag is one of the most commonly used packaging forms in the plastic industry and the saline-alkali chemical industry. The bag is generally a white woven bag made of PE material or PP material. In the raw material feeding link of the plastic processing industry and other saline-alkali chemical industries, generally, workers manually cut the bag and put plastic particles, saline-alkali materials, etc. into the feeding port. This feeding method has a large labor intensity and a low feeding efficiency.

[0003] In patent CN117104648A, a material breaking mechanism is provided. The material breaking mechanism includes a workbench, a feeding channel is opened on the workbench, and a flange extending away from the workbench is provided at the feeding end of the feeding channel; a puncturing part, the distal end of the puncturing part is connected to the feeding end, and the outer diameter of the distal end is smaller than the inner diameter of the flange. The proximal end of the puncturing part forms a puncturing tip, and at least near the puncturing tip, a hollow part is opened on the puncturing part, and the hollow part is communicated with the feeding channel; a magnetic separation device is arranged at the discharging end of the feeding channel for removing impurities from the lithium battery materials. The settings of the flange and the puncturing part can dynamically seal the opening of the packaging bag after the material package to be fed is punctured, so that the material enters the feeding channel through the hollow part of the puncturing tip, reducing the occurrence of material overflow, moisture exceeding the standard, mixing of metal impurities and other failure forms.

[0004] In the prior art, a conical structure is usually used to open the soft bag. When the conical puncturing tip is designed or used, if the taper is small, the cross-section of the hollow part is also small; if the taper is large, it is difficult to puncture the soft bag. In addition, after the conical puncturing tip punctures the soft bag, it will extrude the edge of the puncture opening of the soft bag outward, thus forming an annular wrinkled area, making it difficult to completely feed the material. Summary of the Invention

[0005] The purpose of the present invention is to provide a high-speed unpacking and feeding device to solve the problems that the existing feeding device is difficult to puncture the soft bag and it is difficult to completely feed the material.

[0006] To achieve the above purpose, the present invention provides a high-speed unpacking and feeding device, including:

[0007] A hopper;

[0008] An unpacking assembly, including a cutting blade, and the cutting blade is installed in the hopper;

[0009] The lifting assembly includes a lifting structure and a bracket. The bracket is disposed within the hopper. The bracket has a first position higher than the cutting blade and a second position not higher than the cutting blade. The bracket is fixedly connected to the lifting structure, and the lifting structure drives the bracket to move between the first position and the second position.

[0010] Preferably, the bracket includes a first frame body and a second frame body disposed on both sides of the cutting blade.

[0011] Preferably, the lifting assembly further includes a connecting frame, and the bracket is fixedly connected to the lifting structure through the connecting frame.

[0012] Preferably, the lifting assembly further includes a guiding structure. The guiding structure includes a smooth shaft and a linear bearing.

[0040] The following provides a detailed description of the specific embodiments of the present invention. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not intended to limit the present invention.

[0041] In the present invention, unless otherwise stated, the orientation terms such as "upper" and "lower" generally refer to the orientation in the assembled and used state. "Inner" and "outer" refer to the inner and outer of the contour of each component itself.

[0042] In the present invention, a high-speed unpacking and feeding device is provided, as Figures 1 to 5 shown, including:

[0043] Hopper 1, the top of the hopper 1 is provided with an opening for receiving materials, and the bottom of the hopper 1 is provided with an opening for collecting materials and guiding the materials;

[0044] Breaking package assembly 2, the breaking package assembly 2 is used to break the soft package to form an opening for material leakage. The breaking package assembly 2 includes a cutting disc 21, the cutting disc 21 has a cutting edge, and the cutting disc 21 is installed in the hopper 1. Specifically, the cutting disc 21 is vertically installed with the cutting edge upward; preferably, the cutting disc 21 is installed in the upper part of the hopper 1;

[0045] Lifting assembly 3, the lifting assembly 3 is used to lift the flexible package and drive the flexible package to move. The lifting assembly 3 includes a lifting structure 31 and a bracket 32. The bracket 32 is arranged in the hopper 1. The bracket 32 has a first position higher than the cutting blade 21 and a second position not higher than the cutting blade 21. The bracket 32 is fixedly connected to the lifting structure 31, and the lifting structure 31 drives the bracket 32 to move between the first position and the second position. Herein, the "higher than the cutting blade 21" means higher than the cutting edge of the cutting blade 21. Specifically, the first position may be entirely higher than the cutting edge of the cutting blade 21, or the first position may be partially higher than the cutting edge of the cutting blade 21; the "not higher than the cutting blade 21" means not higher than the cutting edge of the cutting blade 21. Specifically, the second position may be entirely not higher than the cutting edge of the cutting blade 21, or the second position may be partially not higher than the cutting edge of the cutting blade 21; at this time, the bracket 32 may be entirely below the cutting edge of the cutting blade 21 in the second position, or may be below the bottom of the cutting blade 21. The lifting mechanism includes a pneumatic lifting mechanism, an electric lifting structure 31 or a lifting mechanism driven by an internal combustion engine; specifically, the lifting mechanism includes a cylinder or an electric push rod.

[0046] In the high-speed unpacking and feeding device of the present invention, by setting the lifting assembly 3, the flexible package filled with materials is placed on the bracket 32 in the first position. The bracket 32 moves downward to the second position, and the flexible package falls onto the bag-breaking assembly 2 under the action of gravity, so that the flexible package is completely cut, and a larger opening is formed at the bottom of the flexible package, improving the material dropping speed; this process makes full use of the gravity of the flexible package and does not require additional structures or energy to complete the bag-breaking action, making the device simple in structure, energy-saving and environmentally friendly; at the same time, since the distance between the first position and the second position is fixed, the cutting force of the bag-breaking assembly 2 on the flexible package is consistent, which is beneficial to controlling the size of the incision of the flexible package to be consistent. Further, it is beneficial to control the constancy of the feeding amount; the cut flexible package can be driven by the bracket 32 to move up and down reciprocally, so that the materials in the flexible package can quickly and as little as possible fall into the hopper 1 without omission; by arranging the cutting blade 21 in the hopper 1, the cutting blade 21 can cut the flexible package to form a flat opening at the bottom of the flexible package, and the materials fall into the hopper 1 from the opening, solving the problem of incomplete feeding.

[0047] Herein, the high-speed unpacking and feeding device further includes a frame 6, and the hopper 1 is installed on the frame 6.

[0048] Preferably, as Figures 6 to 7As shown, the bracket 32 includes a first frame body 321 and a second frame body 322 disposed on both sides of the cutting blade 21. A space for avoiding the cutting blade 21 is formed between the first frame body 321 and the second frame body 322. The first frame body 321 and the second frame body 322 support both sides of the flexible package simultaneously, which is beneficial to keeping the flexible package stable during the blanking process. Preferably, there are two sets of the brackets 32, and the two sets of brackets 32 generally enclose a rectangle, so as to support the flexible package from multiple angles. Further, the upper parts of the first frame body 321 and the second frame body 322 are inclined in directions away from each other. The inclined first frame body 321 and second frame body 322 can provide guidance for the materials in the flexible package and avoid leakage of materials in the flexible package.

[0049] In order to enable the lifting mechanism to drive the bracket 32 to move, the jacking assembly 3 further includes a connecting frame 33. The bracket 32 is fixedly connected to the lifting structure 31 through the connecting frame 33. Specifically, as Figure 1 shown, in order to improve the service life of the lifting mechanism, the lifting structure 31 is installed outside the hopper 1. The connecting frame 33 is L-shaped. One end of the connecting frame 33 is connected to the lifting structure 31, and the other end is connected to the bracket 32.

[0050] In order to fix the movement path of the bracket 32, as Figure 6 shown, the jacking assembly 3 further includes a guiding structure 34. The guiding structure 34 includes an optical axis and a linear bearing. The linear bearing is disposed on one side of the lifting structure 31. One end of the optical axis is fixedly connected to the connecting frame 33, and the other end passes through the linear bearing and cooperates with the linear bearing.

[0051] In order to increase the blanking speed, as Figure 8 shown, there are multiple cutting blades 21, and the multiple cutting blades 21 are arranged at intervals. According to an embodiment of the present invention, the multiple cutting blades 21 are arranged in an X shape. The cutting blades 21 arranged in an X shape are adapted to the rectangular flexible package, so that the cutting blades 21 can form a larger opening at the bottom of the flexible package at one time. According to another embodiment of the present invention, the multiple cutting blades 21 are arranged in a cross shape. In addition, there is one cutting blade 21, and the cutting blade 21 is in a C shape or a ring shape, which can also achieve the purpose of rapid blanking.

[0052] In the above, as Figure 8 shown, the bag-breaking assembly 2 further includes a cutting bracket 22. The cutting blade 21 is installed on the cutting bracket 22, and the cutting bracket 22 is fixedly connected to the hopper 1.

[0053] In order to form a complete cut at the bottom of the soft bag, the cutting blade 21 is tilted in the horizontal direction, and preferably, the end of the cutting blade 21 close to the hopper 1 is higher than the end of the cutting blade 21 away from the hopper 1. When the soft bag contacts the cutting blade 21, a shear force is formed between the tilted cutting blade 21 and the soft bag, making the soft bag easy to cut.

[0054] Preferably, Figure 8 As shown, the blade of the cutting blade 21 includes a sawtooth segment and a flat blade segment, the sawtooth segment is arranged at one end of the cutting blade 21 away from the hopper 1, and the flat blade segment is arranged at one end of the cutting blade 21 close to the hopper 1. Since the pressure between the center of the soft bag and the cutting blade 21 is smaller than the pressure between the edge of the soft bag and the cutting blade 21, the blade of the sawtooth segment is arranged to cut the soft bag.

[0055] In order to avoid the material remaining in the soft bag as much as possible, according to one embodiment of the present invention, the high-speed unpacking and feeding device also includes a blowing component 4, the blowing component 4 is used to blow gas into the soft bag, so that the gas drives the material remaining in the soft bag to move, and the blowing component 4 includes a blowing pipe 41, and the blowing pipe 41 is installed on the cutting blade 21; preferably, the blowing component 4 also includes an air source, and the blowing pipe 41 is connected to the air source. Such a setting makes it possible to clean up the residual material in situ without moving in the horizontal direction after the soft bag leaks, thereby improving the cleaning efficiency; in addition, since the blowing pipe 41 is installed on the cutting blade 21, the blowing pipe 41 can extend into the soft bag without being blocked and blow air into the soft bag. Preferably, the blowing pipe 41 is installed at one end of the cutting blade 21 close to the hopper 1, and such a setting is conducive to efficient cleaning of the four corners of the soft bag that are easy to hide materials.

[0056] In order to drive the soft bag movement after feeding, such as Figure 2 As shown, the high-speed unpacking and feeding device also includes a two-way motion component 5, a workbench 51 is installed below the two-way motion component 5, the two-way motion component 5 drives the workbench 51 to move horizontally and vertically, and a suction cup 52 is arranged on the workbench 51. When the soft package falls, the two-way motion component 5 drives the workbench 51 to move above the soft package, and after the suction cup 52 adsorbs the soft package, the two-way motion component 5 drives the soft package away from the package breaking component 2.

[0057] Preferably, a bottom surface is formed at the bottom of the workbench 51. When the flexible package is placed on the bracket 32 and the bracket 32 is in the first position, the two-way movement assembly 5 drives the workbench 51 to move above the flexible package. The workbench 51 moves downward until it contacts the upper surface of the flexible package. Subsequently, the bracket 32 moves to the second position. At the same time, the workbench 51 moves downward to squeeze the flexible package downward, so that the flexible package not only contacts the cutting blade 21 under the action of gravity, but also contacts the cutting blade 21 under the pressing force of the workbench 51, thereby making it easier to cut the flexible package completely.

[0058] According to another embodiment of the present invention, as Figure 9 shown, the high-speed unpacking and feeding device further includes a blowing assembly 4. The blowing assembly 4 includes a plurality of blow pipes 41 arranged in different directions. The blowing assembly 4 is arranged in the hopper 1 and on one side of the bag-breaking assembly 2. When the blanking of the flexible package is completed, the two-way movement assembly 5 drives the flexible package to move to one side of the bag-breaking assembly 2 and above the blowing assembly 4. Subsequently, the two-way movement assembly 5 drives the flexible package to move downward, and the blowing assembly 4 extends into the flexible package for purging; such a setting makes the purging process not occupy the blanking position and improves the feeding amount of the entire feeding process.

[0059] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solutions of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0060] In addition, it should be noted that, among the various specific technical features described in the above specific embodiments, they can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the present invention will not separately describe various possible combination methods.

[0061] In addition, any combination can be made between various different embodiments of the present invention as long as it does not violate the idea of the present invention, and it should also be regarded as the content disclosed by the present invention.
