This protects components such as the linear guide rail, traveling trolley, and sensors located at the top of the equipment, making the equipment suitable for unpacking dusty materials and improving its applicability.

Description

Technical Field

[0001] This utility model belongs to the field of unpacking machines, specifically relating to a layer-by-layer unpacking machine for unpacking powder. Background Technology

[0002] Packaging unpacking machines are mainly used for unpacking various bagged products. Previously, semi-automatic unpacking machines were primarily used, requiring manual control of the unpacking and unloading processes. This necessitated teamwork and resulted in high labor intensity, low efficiency, and potential for injury and environmental pollution. Furthermore, these machines were sometimes used to unpack products with pungent odors, such as urea fertilizers, which could cause occupational diseases due to close contact with the human body. Later, several newer types of packaging unpacking machines were developed, such as spiral unpacking machines, multi-blade unpacking machines, and saw blade unpacking machines.

[0003] In some existing unpacking machines, bags containing materials enter the equipment via a conveyor belt, slide down a chute to the unpacking position, and are then gripped by a lifting and grabbing mechanism. After gripping, the bags are moved to the unpacking area by a trolley mechanism. During this movement, a cutter cuts the bags open, and the material flows into a hopper. The grabbing mechanism then releases the bags, which fall onto a flipping plate. The flipping plate flips, causing the bags to fall into a waste bag collection mechanism, while the trolley moves back to the grabbing position. However, the trolley mechanism requires guide rails and other supporting structures, resulting in a large equipment size that may not meet the space requirements of some customers. Furthermore, when unpacking powder bags, dust accumulates on the top of the equipment, which is difficult to clean and can affect the operation of the linear guide rails and trolley mechanism on the top of the equipment.

[0004] In view of this, there is an urgent need for a layer-by-layer unpacking machine for powder unpacking to solve the above problems. Utility Model Content

[0005] In view of the problems in the prior art, this utility model provides a layer-by-layer unpacking machine for unpacking powder materials, so as to solve the problems in the prior art.

[0006] To achieve the above technical objectives, the technical solution of this utility model is as follows:

[0007] A layer-by-layer unpacking machine for unpacking powder includes a frame, on which a dustproof chamber, an unpacking chamber, a partition plate, a traveling mechanism, and a bag-grabbing mechanism are provided; the dustproof chamber is located on top of the unpacking chamber, and the internal space of the dustproof chamber and the internal space of the unpacking chamber are separated by the partition plate, which has a sliding groove.

[0008] The walking mechanism includes a linear guide rail, a walking trolley, and a connecting member. The linear guide rail and the slide groove extend in the same direction. The linear guide rail is installed inside the dustproof chamber. The walking trolley is slidably installed on the linear guide rail. One end of the connecting member is connected to the walking trolley, and the other end passes through the slide groove and extends into the unpacking chamber.

[0009] The slide groove is equipped with accordion curtains on both sides of the connector;

[0010] The bag-grabbing mechanism is located below the partition plate and on the connector. The bag-grabbing mechanism is used to grab bags.

[0011] The unpacking compartment includes an unpacking and unloading station and an empty bag collection station arranged side by side in a horizontal direction. A bag grabbing station is provided on one side of the unpacking compartment. The unpacking and unloading station is located between the empty bag collection station and the bag grabbing station. The linear guide rail extends from directly above the bag grabbing station to directly above the unpacking and unloading station. A bag inlet is provided on the side of the unpacking compartment near the bag grabbing station.

[0012] The unpacking and unloading station is equipped with a cutting mechanism, a bag shaking mechanism, and a feeding hopper. The feeding hopper is located at the bottom of the unpacking chamber, the bag shaking mechanism is located directly above the feeding hopper, and the cutting mechanism is located on the side of the bag shaking mechanism near the bag inlet. The cutting mechanism is used to cut the bags entering the unpacking and unloading station, and the bag shaking mechanism is used to separate the material and waste bags, leaving the waste bags above the bag shaking mechanism and allowing the material to fall into the feeding hopper.

[0013] The cutting mechanism includes a rotating shaft, several circular blades, and a driving component. The rotating shaft is horizontally arranged inside the unpacking compartment, and the axial direction of the rotating shaft is perpendicular to the extension direction of the linear guide rail. Several blades are coaxially sleeved on the rotating shaft, and the driving component is used to drive the rotating shaft to rotate.

[0014] The bag-shaking mechanism includes several U-shaped bag-shaking rods with downward openings, a connecting frame, and a first driving component. The connecting frame is located inside the unpacking compartment. Several U-shaped bag-shaking rods are arranged side by side on the connecting frame in a direction perpendicular to the linear guide rail. The first driving component is used to drive the connecting frame to shake.

[0015] The bag-grabbing mechanism includes a lifting module and a bag-grabbing component disposed on the lifting module. The lifting module is disposed on a connecting member, and the bag-grabbing component is used to fix the bag.

[0016] The bag-grabbing assembly includes a bag-grabbing bracket mounted on the lifting module and several bag-grabbing claws mounted at the bottom of the bag-grabbing bracket.

[0017] A bag-pulling assembly is provided on one side of the bag-grabbing bracket. The bag-pulling assembly includes several levers arranged in parallel along the vertical direction of the linear guide rail and a second driving member. One end of each lever is rotatably mounted on one side of the bag-grabbing bracket, and the second driving member is used to drive the levers to rotate synchronously.

[0018] The empty bag collection station is equipped with an upward-facing empty bag collection cylinder, and a spiral auger is installed inside the empty bag collection cylinder.

[0019] A dust removal interface is provided on one side of the unpacking compartment.

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0026] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0027] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0028] refer to Figure 1-2 The powder unpacking machine shown includes a frame, on which a dustproof chamber 1, an unpacking chamber 2, a partition plate 3, a traveling mechanism, and a bag gripping mechanism are arranged. The dustproof chamber 1 is located on top of the unpacking chamber 2. The internal space of the dustproof chamber 1 and the internal space of the unpacking chamber 2 are separated by the partition plate 3. The partition plate 3 is provided with a sliding groove, which is straight.

[0029] The traveling mechanism includes a linear guide rail, a traveling trolley 4, and a connecting piece. The linear guide rail and the slide groove extend in the same direction. The linear guide rail is set inside the dustproof chamber 1. The traveling trolley 4 is slidably set on the linear guide rail. One end of the connecting piece is connected to the traveling trolley 4, and the other end passes through the slide groove and extends into the unpacking chamber 2.

[0030] A pleated curtain 8 is provided on both sides of the connector inside the slide groove, and the two pleated curtains 8 are respectively connected to the two ends of the slide groove.

[0031] The bag-grabbing mechanism is located below the compartment plate 3 and is mounted on the connecting piece. The bag-grabbing mechanism is used to grab bags. Two slides can be arranged in parallel, and two corresponding connecting pieces are also arranged, so that the bag-grabbing mechanism can be driven to move more stably when the traveling trolley 4 moves.

[0032] Based on the above structure, by installing a partition plate 3, the internal space of the equipment is divided into two compartments: the unpacking compartment 2 and the dustproof compartment 1. The traveling trolley 4 is located in the dustproof compartment 1. A groove is left on the partition plate 3, and the connector passes through the partition plate 3 to connect to the bag-grabbing mechanism below the partition plate 3, so that the traveling trolley 4 can drive the bag-grabbing mechanism to move horizontally back and forth. Dustproof accordion curtains 8 are installed on both sides of the connector. The dustproof accordion curtains 8 have the property of being able to stretch and fold. One end of each dustproof accordion curtain is fixed to the connector, and the other end is fixed to the end of the groove. This ensures that when the traveling trolley 4 moves back and forth, the dust in the unpacking compartment 2 cannot enter the dustproof compartment 1 through the partition plate 3, thereby ensuring that dust will not accumulate on the top of the equipment. This protects the linear guide rail, traveling trolley 4, and sensors located on the top of the equipment, making the equipment suitable for unpacking dusty materials and improving the applicability of the equipment.

[0033] like Figure 1 As shown, the unpacking compartment 2 includes an unpacking and unloading station and an empty bag collection station arranged side by side in the horizontal direction. A bag gripping station is set on one side of the unpacking compartment 2. The unpacking and unloading station is located between the empty bag collection station and the bag gripping station. A linear guide rail extends from directly above the bag gripping station to directly above the unpacking and unloading station. A bag inlet is set on the side of the unpacking compartment 2 near the bag gripping station. Thus, during processing, the bags are stacked at the unpacking and unloading station, gripped by the bag gripping mechanism, and then enter the unpacking compartment 2 through the bag inlet to reach the unpacking and unloading station for unpacking and unloading.

[0034] like Figure 1 As shown, the unpacking and unloading station is equipped with a cutting mechanism, a bag shaking mechanism, and a hopper 7. The hopper 7 is located at the bottom of the unpacking chamber 2, the bag shaking mechanism is located directly above the hopper 7, and the cutting mechanism is located on the side of the bag shaking mechanism near the bag inlet. Thus, the bag is transported to the unpacking and unloading station by the bag grabbing mechanism, the bag is cut by the cutting mechanism, and the material and waste bag are separated by the bag shaking mechanism, leaving the waste bag above the bag shaking mechanism and letting the material fall into the hopper 7.

[0035] The cutting mechanism specifically includes a rotating shaft 5, several circular blades 6, and a driving component. The rotating shaft 5 is horizontally positioned inside the unpacking chamber 2, and its axial direction is perpendicular to the extension direction of the linear guide rail. Several blades 6 are coaxially mounted on the rotating shaft 5 (the optimal spacing between two adjacent blades 6 is 10mm-15mm). The driving component is used to drive the rotating shaft 5 to rotate. The driving component can be a motor, which is coaxially connected to the rotating shaft 5. The cutting of the bag is completed by several blades 6 on the same rotating shaft 5, ensuring the stability of the cutting effect and the synchronization of the blades 6, and preventing the problem of incomplete cutting of the packaging bag. It solves the problems of high resistance when spiral blades cut and high resistance when curved blades cut in, which easily cause blade breakage.

[0036] The bag-shaking mechanism specifically includes several U-shaped bag-shaking rods 9 with downward openings, a connecting frame, and a first driving component. The connecting frame is located inside the unpacking chamber 2. Several U-shaped bag-shaking rods 9 are arranged side by side on the connecting frame in a direction perpendicular to the linear guide rail. The first driving component is used to drive the connecting frame to shake. The first driving component can use a cylinder as power to drive the push rod on the connecting frame to slide back and forth, driving the U-shaped bag-shaking rods 9 to shake, achieving the effect of rapid unloading. This ensures that the material enters the hopper 7 under the action of gravity, reducing residual material in the bag. The bag will remain on several U-shaped bag-shaking rods 9 (the distance between two adjacent U-shaped bag-shaking rods 9 is small, and the bag cannot pass through).

[0037] like Figure 1 As shown, the bag-grabbing mechanism includes a lifting module 10 and a bag-grabbing assembly mounted on the lifting module 10. The lifting module 10 is mounted on a connector. The bag-grabbing assembly includes a bag-grabbing bracket 11 mounted on the lifting module 10 and several bag-grabbing claws 12 mounted at the bottom of the bag-grabbing bracket 11. The several bag-grabbing claws 12 are divided into multiple groups and are arranged opposite each other. The bag-grabbing claws are inserted into the bag under the drive of a cylinder to fix the bag. The lifting module 10 is used to drive the bag-grabbing bracket 11 to perform lifting and lowering movements to complete the extraction of the bag. The lifting module can be composed of a cylinder.

[0038] Further optimization involves a bag-removing assembly on one side of the bag-grabbing bracket 11 to clean the bags remaining on the U-shaped bag-shaking rod 9. This assembly includes several levers arranged parallel to each other along the vertical direction of the linear guide rail, and a second driving component. One end of each lever is rotatably mounted on one side of the bag-grabbing bracket 11. The second driving component drives the levers to rotate synchronously. The gap between adjacent levers is adapted to the width of the U-shaped bag-shaking rod 9, meaning that the levers can be sequentially inserted into the gaps between the U-shaped bag-shaking rods 9. When the bag-grabbing bracket 11 moves towards the U-shaped bag-shaking rod 9, the second driving component drives the levers to rotate. The movement of the lever vertically positions it. When the lever enters the gap between the U-shaped shaking rods 9, it pushes the waste bags remaining on the U-shaped shaking rods 9 to the empty bag collection station. When the bag grabbing bracket 11 moves towards the bag grabbing station, the second drive unit drives the lever to rotate, making the lever parallel and preventing the waste bags remaining on the U-shaped shaking rods 9 from being pushed towards the bag grabbing station. When the traveling trolley 4 moves towards the unpacking and unloading station, the second drive unit drives the lever to rotate, making the lever vertical and pushing the waste bags on the U-shaped shaking rods 9 to the empty bag collection station, thus completing the cleaning of the waste bags on the U-shaped shaking rods 9.

[0039] like Figure 1 As shown, the empty bag collection station is equipped with an upward-facing empty bag collection cylinder 13. A spiral auger is installed inside the empty bag collection cylinder 13. Waste bags are pushed down into the empty bag collection cylinder 13 by a lever, and are then conveyed to the outside by the rotation and compression of the spiral auger.

[0040] like Figure 1 As shown, a dust removal interface 14 is provided on one side of the unpacking chamber 2. Except for the feed port and other necessary openings, the rest of the chassis is sealed. Before the equipment is run, the dust removal interface 14 is connected to the dust removal equipment on site. Through the work of the dust removal equipment, a negative pressure space is formed in the unpacking chamber 2 to prevent the dust generated during the unpacking operation from overflowing and to prevent dust from entering the dustproof chamber 1 and the outside of the equipment.

[0041] In summary, by installing the partition plate 3, the internal space of the equipment is divided into two compartments: the unpacking compartment 2 and the dustproof compartment 1. The traveling trolley 4 is located in the dustproof compartment 1. A groove is left on the partition plate 3, and the connector passes through the partition plate 3 to connect to the bag-grabbing mechanism below the partition plate 3, so that the traveling trolley 4 can drive the bag-grabbing mechanism to move horizontally back and forth. Dustproof accordion curtains 8 are installed on both sides of the connector. The dustproof accordion curtains 8 have the property of being able to stretch and fold. One end of each dustproof accordion curtain is fixed to the connector, and the other end is fixed to the end of the groove. This ensures that when the traveling trolley 4 moves back and forth, the dust in the unpacking compartment 2 cannot enter the dustproof compartment 1 through the partition plate 3, thereby ensuring that dust will not accumulate on the top of the equipment. This protects the linear guide rail, traveling trolley 4, and sensors located on the top of the equipment, making the equipment suitable for unpacking dusty materials and improving the applicability of the equipment.

[0042] This application can be used with various types of packaging bags, such as woven bags, plastic bags, paper bags, etc., as well as bags of different specifications and materials, to meet the packaging needs of different industries.

[0043] The equipment in this application has a high degree of automation, which reduces the chance of manual contact with materials, reduces the impact of dust pollution on the production environment, helps to improve the working environment, and meets the requirements of environmental protection and safe production.

[0044] The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that can be directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
