Description

Technical Field

[0001] This invention relates to the field of unpacking machine technology, specifically to an unpacking machine with a dust removal structure. Background Technology

[0002] A packaging unpacking machine is a mechanical device used to dismantle packaging materials, primarily in industrial production. It's used to unpack various types of packaging, such as cartons, plastic bags, and plastic buckets. This machine improves unpacking efficiency, reduces the labor intensity of manual unpacking, and also reduces environmental pollution. Common packaging unpacking machines, such as ton bag unpacking machines, are used to unpack and feed bagged materials. In the production processes of many industries, material unpacking is an indispensable and crucial step. As the core equipment for automating this operation, the performance of the packaging unpacking machine directly affects production efficiency, the working environment, and material utilization. With the acceleration of industrialization, enterprises are placing increasingly higher demands on the automation level, adaptability, and environmental friendliness of packaging unpacking machines.

[0003] However, existing unpacking machines still have many problems that need to be solved in practical applications. The cutting mechanisms of existing unpacking machines are mostly fixed structures, and the extension length of the cutting blades cannot be flexibly adjusted according to the thickness and hardness of the bagged material and the packaging bag material. When dealing with packaging bags of different sizes, the fixed-length blades are prone to incomplete or excessive cutting: incomplete cutting will prevent the material from falling smoothly, requiring manual secondary processing and reducing production efficiency; excessive cutting may damage the blades and increase the risk of packaging bag debris mixing into the material, affecting the purity of the material. Secondly, poor material feeding is a common defect of existing unpacking machines. After unpacking, the material is easily adhered to the inner wall of the storage bin due to its own stickiness and bulk density, or forms bridging and blockages in the storage bin, resulting in slow feeding speed or even interruption. Regular manual cleaning is required, which not only increases the labor intensity of operators but also seriously affects the continuity of production. Furthermore, the unpacking operation generates a large amount of dust, which not only pollutes the working environment and endangers the health of operators but may also cause safety hazards due to dust accumulation.

[0004] To address the aforementioned issues, innovative designs are urgently needed based on existing approaches. Summary of the Invention

[0005] The purpose of this invention is to provide a packaging unpacking machine with a dust removal structure to solve the problems mentioned in the background. The technical solution of this invention addresses the problem that the existing technical solutions are too simplistic and provides a solution that is significantly different from the existing technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a packaging unpacking machine with a dust removal structure, comprising a mounting frame, an inverted conical feeding hopper fixedly mounted on the mounting frame, a storage box fixedly mounted at the lower end of the mounting frame, symmetrical side support plates fixedly mounted at the left and right ends of the mounting frame, a rotating motor fixedly mounted on the outer side of the side support plates, a rotating shaft rotatably mounted on the inner side of the side support plates, a cutting machine body connected and mounted on the rotating shaft, and multiple sets of cutting blades arranged at equal angles on the cutting machine body; A cutting adjustment mechanism is installed inside the cutting machine body and is used to adjust the extension and retraction of the cutting blade. An auxiliary feeding mechanism is provided, which is located in the internal cavity of the side support plate. The auxiliary feeding mechanism is used to assist in feeding the storage box.

[0007] Preferably, the cutting adjustment mechanism includes a connector, which is slidably installed inside the cutting machine body at equal angles, and the connector is fixedly connected to the cutting blade.

[0008] Preferably, the cutting adjustment mechanism further includes a pressure spring, which is disposed at equal angles inside the cutting machine body and is symmetrical about the cutting blade.

[0009] Preferably, one end of the pressure spring is fixedly connected to the inner wall of the cutting machine body, and the other end is fixed to the connector, with the pressure springs evenly distributed on the connector.

[0010] Preferably, the auxiliary feeding mechanism includes a connecting block, which is connected to the output end of the rotating motor. The connecting block is installed through the side support plate, and the other end of the connecting block is connected to the rotating shaft. A deflection wheel is fixedly installed on the connecting block, and the deflection wheel is disposed inside the side support plate.

[0011] Preferably, the auxiliary feeding mechanism includes an abutment block, which is slidably installed inside the side support plate by a slider. The abutment block is shaped like an "A" when viewed from the front. Limiting blocks are fixedly installed at equal intervals on the abutment block. The limiting blocks are arc-shaped when viewed from the side. The bottom of the abutment block abuts against the surface of the deflection wheel.

[0012] Preferably, the auxiliary feeding mechanism further includes an abutment rod, which is elastically slidably mounted on the side support plate. An impact block is fixedly mounted on the top end of the abutment rod, and the tail end of the abutment rod is arc-shaped. The abutment rod is symmetrically arranged on the side support plate when viewed from the side, and the arc end of the abutment rod corresponds to the arc end of the limiting block.

[0013] Preferably, dust suction ports are symmetrically arranged on both sides of the upper end of the side wall of the storage box, and a receiving plate is rotatably installed on the inner wall of the storage box, with a half gear fixedly installed on the receiving plate.

[0014] Preferably, an extrusion plate is slidably installed inside the storage box, and a rack is fixedly installed at the bottom of the extrusion plate, the rack meshing with a half gear.

[0015] Preferably, a piston cylinder is fixedly installed inside the storage box, the piston rod on the piston cylinder is connected to the upper end of the extrusion plate, and the ventilation pipe of the piston cylinder is interconnected with the dust suction port.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. Strong cutting adaptability and excellent cutting effect: This invention, by setting a cutting adjustment mechanism inside the cutting machine body, utilizes the fixed connection between the connecting parts and the cutting blade, combined with the elastic action of the pressure spring, to achieve flexible adjustment of the cutting blade's extension and retraction. When cutting packaging bags of different thicknesses, hardnesses, or materials, the cutting machine body will adjust different rotation speeds according to different materials. This allows the pressure spring to automatically adjust the extension length of the connecting rod according to the centrifugal force generated by different rotation speeds, thereby driving the cutting blade to achieve adaptive extension and retraction, avoiding the problems of incomplete or over-cutting that occur with fixed-length blades. Simultaneously, the pressure springs are symmetrically distributed about the connecting rod on both sides and at equal distances, ensuring the stability of the connecting rod during extension and retraction, further improving the uniformity and reliability of the cutting, effectively reducing the risk of packaging bag debris mixing into the material, ensuring material purity, and increasing the overall applicability of the device.

[0017] 2. Highly efficient and stable auxiliary feeding, reducing labor intensity: The auxiliary feeding mechanism of this invention shares a drive source with the rotary motor, eliminating the need for an additional independent drive device. This not only simplifies the equipment structure and reduces manufacturing costs and energy consumption, but also ensures the coordination between the auxiliary feeding action and the cutting action. While the rotary motor drives the rotating shaft to rotate and cut the machine body, it simultaneously drives the deflection wheel to rotate synchronously via a connecting rod. During rotation, the deflection wheel abuts against the bottom of the abutment block, pushing the abutment block to slide up and down inside the side support plate via a slider. The arc-shaped limiting block on the abutment block cooperates with the arc end of the abutment rod, causing the abutment rod to slide elastically on the side support plate, thereby periodically impacting the feeding bin through the impact block. This periodic impact effectively prevents material adsorption and accumulation on the inner wall of the storage bin, preventing bridging and blockage, accelerating material descent, significantly improving feeding efficiency, ensuring the long-term stable operation of the auxiliary feeding mechanism, reducing the frequency of manual cleaning, and lowering the labor intensity of operators.

[0018] 3. Excellent dust removal effect and environmentally friendly: This invention achieves highly efficient dust removal by setting symmetrical dust suction ports on the upper side wall of the storage box, combined with the linkage structure of the piston cylinder, extrusion plate, and receiving plate. After the material is unpacked, it falls onto the receiving plate. The gravity of the material drives the receiving plate to rotate. The half gear on the receiving plate meshes with the rack at the bottom of the extrusion plate, causing the extrusion plate to slide up and down inside the storage box. The upper part of the extrusion plate is connected to the piston rod of the piston cylinder. During the up and down movement of the extrusion plate, it drives the piston inside the piston cylinder to move, so that the piston cylinder forms a negative pressure adsorption effect through the ventilation pipe and the dust suction port, which efficiently adsorbs the dust generated in the storage box. This dust removal structure that uses the gravity of the material as a driving force does not require an additional dust suction drive device, further simplifying the equipment structure and reducing energy consumption. At the same time, the symmetrically set dust suction ports expand the dust suction range, which can comprehensively adsorb dust in different areas of the storage box, significantly improving the dust removal effect, effectively improving the working environment, protecting the health of operators, and reducing the safety hazards caused by dust accumulation.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention.

[0022] Please see Figures 1-9 The present invention provides a technical solution: a packaging unpacking machine with a dust removal structure, including a mounting frame 1, an inverted conical feeding bin 2 fixedly mounted on the mounting frame 1, a storage box 3 fixedly mounted at the lower end of the mounting frame 1, symmetrical side support plates 4 fixedly mounted at the left and right ends of the mounting frame 1, a rotating motor 5 fixedly mounted on the outer side of the side support plate 4, a rotating shaft 6 rotatably mounted on the inner side of the side support plate 4, a cutting machine body 7 connected and mounted on the rotating shaft 6, and multiple sets of cutting blades 8 arranged at equal angles on the cutting machine body 7; The cutting adjustment mechanism is located inside the cutting machine body 7 and is used to adjust the extension and retraction of the cutting blade 8. An auxiliary feeding mechanism is installed in the internal cavity of the side support plate 4. The auxiliary feeding mechanism is used to assist the feeding of the storage box 3.

[0023] As one embodiment of the present invention, the cutting adjustment mechanism includes a connector 9, which is slidably installed inside the cutting machine body 7 at equal angles, and the connector 9 is fixedly connected to the cutting blade 8.

[0024] As one embodiment of the present invention, the cutting adjustment mechanism further includes a pressure spring 10, which is arranged at equal angles inside the cutting machine body 7 and is symmetrical about the cutting blade 8.

[0025] In one embodiment of the present invention, one end of the pressure spring 10 is fixedly connected to the inner wall of the cutting machine body 7, and the other end is fixed to the connector 9. The pressure springs 10 are evenly distributed on the connector 9.

[0026] Start the rotating motor 5. The output end of the rotating motor 5 drives the connecting rod to rotate. The connecting rod synchronously drives the rotating shaft 6 to rotate. The rotating shaft 6 then drives the cutting machine body 7 and its multiple sets of cutting blades 8 to rotate at high speed. Under the action of the pressure spring 10 and the connecting piece 9, the cutting blades 8 extend to different lengths under the action of centrifugal force according to the different speeds of the cutting machine body 7, so as to realize the cutting and unpacking operation of the packaging bag.

[0027] As one embodiment of the present invention, the auxiliary feeding mechanism includes a connecting block 11, which is connected to the output end of the rotating motor 5. The connecting block 11 is installed through the side support plate 4, and the other end of the connecting block 11 is connected to the rotating shaft 6. A deflection wheel 12 is fixedly installed on the connecting block 11, and the deflection wheel 12 is disposed inside the side support plate 4.

[0028] As one embodiment of the present invention, the auxiliary feeding mechanism includes an abutment block 13, which is slidably installed inside the side support plate 4 via a slider 14. The abutment block 13 is shaped like an "A" when viewed from the front. Limiting blocks 15 are fixedly installed at equal intervals on the abutment block 13. The limiting blocks 15 are arc-shaped when viewed from the side. The bottom of the abutment block 13 abuts against the surface of the deflection wheel 12.

[0029] As one embodiment of the present invention, the auxiliary feeding mechanism further includes an abutment rod 16, which is elastically slidably mounted on the side support plate 4. An impact block 17 is fixedly mounted on the top end of the abutment rod 16. The tail end of the abutment rod 16 is arc-shaped. The abutment rod 16 is symmetrically arranged on the side support plate 4 when viewed from the side. The arc end of the abutment rod 16 corresponds to the arc end of the limiting block 15.

[0030] When the abutment block 13 slides up and down, the arc surface of the limiting block 15 abuts and slides with the arc end of the abutment rod 16, pushing the abutment rod 16 to slide elastically on the side support plate 4, driving the impact block 17 fixed at the top of the abutment rod 16 to reciprocate synchronously with the abutment rod 16, continuously impacting the side wall of the feeding bin 2, causing the feeding bin 2 to vibrate slightly, promoting the smooth downward flow of internal materials, and avoiding accumulation and blockage; In one embodiment of the present invention, dust suction ports 19 are symmetrically arranged on both sides of the upper end of the side wall of the storage box 3, and a receiving plate 18 is rotatably installed on the inner wall of the storage box 3, and a half gear 1801 is fixedly installed on the receiving plate 18.

[0031] In one embodiment of the present invention, an extrusion plate 20 is slidably installed inside the storage box 3, and a rack 21 is fixedly installed at the bottom of the extrusion plate 20. The rack 21 meshes with the half gear 1801.

[0032] In one embodiment of the present invention, a piston cylinder 23 is fixedly installed inside the storage box 3. The piston rod 22 on the piston cylinder 23 is connected to the upper end of the extrusion plate 20. The ventilation pipe of the piston cylinder 23 is connected to the dust suction port 19.

[0033] The ventilation pipe of the piston cylinder 23 is interconnected with the dust suction ports 19 symmetrically arranged on both sides of the upper end of the side wall of the storage box 3. When the piston rod 22 of the piston cylinder 23 drives the extrusion plate 20 to slide up and down, a negative pressure is generated inside the piston cylinder 23, which is transmitted to the dust suction port 19 through the ventilation pipe, causing the dust suction port 19 to generate suction force, and sucking the dust generated during cutting and material falling into the piston cylinder 23 or the external dust removal equipment.

[0034] Working principle: After the equipment is started, the material package to be unpacked is fed into the inverted conical feed hopper 2 above the mounting frame 1. The feed hopper 2 adopts an inverted conical design, which can use gravity to achieve directional sliding of the material package, accurately guiding it into the cutting area and avoiding the problem of insufficient cutting caused by the material package deviating. At this time, the storage box 3 is in the receiving state, and its internal receiving plate 18 is initially kept in a horizontal position, providing a temporary receiving surface for the cut material; The rotating motor 5 on the outside of the side support plate 4 starts, and drives the rotating shaft 6 to rotate through the connecting block 11 connected to the output end. This drives the cutting machine body 7 connected to the rotating shaft 6 to rotate synchronously. Multiple sets of cutting blades 8 distributed at equal angles on the cutting machine body 7 rotate at high speed with the cutting machine body 7, and perform ring cutting and unpacking of the material package that slides down from the feed hopper 2, causing the material package to break and release the internal material. At the same time, before cutting the material, the cutting machine body 7 will adjust the rotation speed according to the different types and weights of materials. The connecting part 9 inside the cutting machine body 7 squeezes the pressure spring 10 under the action of centrifugal force, thereby driving the cutting blade 8 to extend to a suitable length to cut the material. The elastic restoring force of the pressure spring 10 acts in the opposite direction on the connecting part 9, causing the cutting blade 8 to adaptively extend and retract. This can avoid damage to the cutting blade 8 due to excessive force and ensure sufficient cutting of the material package. While driving the cutting machine body 7, the rotating motor 5 drives the deflection wheel 12 fixed on it to rotate synchronously through the connecting block 11, thereby triggering the operation of the auxiliary feeding mechanism. When the deflection wheel 12 rotates, its eccentric structure pushes the abutment block 13 to slide up and down along the guide direction of the slider 14, thereby making the arc-shaped limiting block 15 on the abutment block 13 cooperate with the arc end of the abutment rod 16, causing the abutment rod 16 to slide elastically on the side support plate 4, and then periodically impacting the feeding bin 2 through the impact block 17. This periodic impact can effectively prevent the material from adsorbing and accumulating on the inner wall of the feeding bin 2, prevent bridging and blockage, accelerate the falling of the material, and significantly improve the feeding efficiency. After unpacking, the material falls onto the receiving plate 18 inside the storage bin 3. As the material accumulates on the receiving plate 18, its weight gradually increases, pushing the receiving plate 18 to rotate downwards around the rotating connection point on the inner wall of the storage bin 3. A half gear 1801 is fixedly installed on the receiving plate 18. The half gear 1801 meshes with the rack 21 at the bottom of the extrusion plate 20, which is slidably installed inside the storage bin 3. When the receiving plate 18 rotates, it drives the half gear 1801 to rotate. Through meshing with the rack 21, the half gear 1801 drives the extrusion plate 20 to slide upwards inside the storage bin 3. When the receiving plate 18 rotates to a certain angle, the material on it slides down to the lower part of the storage bin 3, reducing the weight on the receiving plate 18. Under the weight of the extrusion plate 20 and the resetting action of the piston cylinder 23, the extrusion plate 20 slides downwards, causing the rack 21 to move in the opposite direction. This, in turn, drives the receiving plate 18 to rotate upwards and reset through the half gear 1801. During the up-and-down sliding process of the extrusion plate 20, its upper end is connected to the piston rod 22 of the piston cylinder 23. The sliding of the extrusion plate 20 drives the piston inside the piston cylinder 23 to reciprocate, creating a periodic negative pressure inside the piston cylinder 23. Since the ventilation pipe of the piston cylinder 23 is interconnected with the dust suction ports 19 symmetrically arranged on the upper side wall of the storage box 3, the negative pressure generated by the piston cylinder 23 is transmitted to the dust suction ports 19 through the ventilation pipe, causing the dust suction ports 19 to generate suction force, which efficiently adsorbs the dust generated in the storage box 3 during the unpacking process, thus achieving the dust removal function.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
