Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to an automated bag-breaking and adding system with a filling bag. Background Technology

[0002] Low-pressure mud solids control systems are an essential part of drilling operations, and the mixing and feeding system within these systems is of paramount importance. Conventional chemical addition involves manually carrying small bags of chemicals to the mixing funnel, manually breaking the bags, and adding the chemicals. This method has several drawbacks: First, the large quantity of chemicals added and the frequent bag-breaking increases worker workload; second, most chemicals are corrosive and can easily cause injury to workers; and third, open-air feeding can lead to dust splashes and environmental pollution. When using bagged materials, workers need to carry the bags to the mixing funnel, cut the bottom of the bags with a knife, and unload from the bottom, posing safety risks.

[0003] Existing mixing and feeding systems are equipped with lifting auxiliary equipment, such as large bag lifting frames or cantilever cranes in the mixing zone to assist in manual feeding. This improves feeding efficiency to some extent and frees up labor. However, this design has a large footprint and extremely high power consumption. Moreover, the dust in the air during manual feeding can cause serious damage to the workers' health. For small bags, frequent feeding and bag breaking can easily cause worker fatigue, seriously affecting feeding and bag breaking efficiency.

[0004] Therefore, it is necessary to propose an automated bag-breaking and adding system for conveyor belts to overcome the shortcomings of existing technologies. Utility Model Content

[0005] The purpose of this invention is to solve the problems of dust causing harm to workers in existing mixing and feeding systems, as well as the low efficiency of feeding and bag breaking. An automated bag breaking and adding system for conveyor belts is provided.

[0006] The technical solution of this utility model is:

[0007] An automated bag-breaking and adding system includes a robotic arm and a shelf holding the bags, a bag-breaking box, and a conveyor belt inside the bag-breaking box. One end of the conveyor belt extends from the entrance of the bag-breaking box to the outside of the box. A pair of cutting blades are installed inside the bag-breaking box, and the pair of cutting blades are slidably connected to the bag-breaking box via guide rails. When the bags move on the conveyor belt, they contact the pair of cutting blades and push them to slide along the guide rails. The cutting blades move horizontally and cut from the middle of the bag to both sides. A return spring is provided on the bag-breaking box to reset the cutting blades.

[0008] Furthermore, the guide rail is slidably connected to a slider, on which a cutting motor is mounted. The cutting motor drives the cutting blade to rotate, and the rotating cutting blade can improve the cutting effect. When the bag comes into contact with the cutting blade, the rotating cutting blade can cut the bag instantly, while the slider can support the cutting blade to move along the guide rail when it is pushed by the bag.

[0009] Furthermore, one end of the return spring is fixedly connected to the top of the bag-breaking box, and the other end is fixedly connected to the slider. The return spring can pull the slider back to the initial position. After the current bag is cut, the bag is also separated from the cutting tool under the action of the conveyor belt. At this time, the cutting tool is no longer pushed by the bag. The return spring will pull the cutting tool to move in the opposite direction along the guide rail, thereby returning to the initial position on the guide rail, which is convenient for cutting the next bag.

[0010] Furthermore, the conveyor belt includes a perforated mesh for transporting the material bags and a chain that drives the perforated mesh to move. The chain is located on both sides of the perforated mesh, and metal spikes are provided on the outer side of the chain. The cut material bags pass through the perforated mesh and fall into the discharge hopper at the bottom of the conveyor belt. The metal detector can penetrate into the material bag, thereby ensuring that the material bag and the conveyor belt do not move relative to each other.

[0011] Furthermore, a first baffle and a second baffle are installed opposite each other at the outlet of the bag breaking box. There is a gap between the first baffle and the second baffle for the waste bag to pass through. After the material bag is cut, the unloaded waste bag will continue to move along the conveyor belt. When it reaches the end of the conveyor belt, the first baffle and the second baffle block the waste bag, so that the waste bag can only pass through the gap between them. During this process, the waste bag will flip and bend, thereby further dispersing the residual material in the waste bag into the discharge funnel, and then the waste bag enters the outlet of the bag breaking box.

[0012] Furthermore, the first baffle is located on top of the second baffle and is fixedly connected to the bag-breaking box, while the second baffle is fixed to the end of the conveyor belt.

[0013] Furthermore, a discharge guide roller is provided at the outlet of the bag breaking box. The discharge guide roller is driven to rotate by a discharge motor. A collection box for collecting waste bags is connected to the outlet of the bag breaking box. The discharge guide roller discharges the waste bags through the outlet of the bag breaking box into the collection box. Rollers are provided on the outside of the bag breaking box near the inlet. The discharge guide roller can push the waste bags out of the outlet of the bag breaking box by spiral thrust and collect them through the collection box. As for the rollers, they can spread out and flatten the bags when they enter the inlet of the bag breaking box, so that the shape of the bags is relatively regular and easier to cut.

[0014] Furthermore, the discharge funnel is connected to a mixing unit, which is located on the outside of the bag-breaking box. The mixing unit can mix the materials evenly.

[0015] Furthermore, the cutting tool includes a cutting blade connecting rod and a cutting blade. One end of the cutting blade connecting rod is fixedly connected to the cutting blade, and the other end of the cutting blade connecting rod is fixedly connected to the cutting motor coaxially.

[0016] Furthermore, conveyor belt covers are provided on both sides of the conveyor belt, and a conveyor belt support frame is fixedly connected to the bottom of the conveyor belt. The conveyor belt support frame is fixed on the conveyor belt fixed platform, which is supported by support legs. The conveyor belt is connected to a conveyor motor and a conveyor gearbox.

[0017] This utility model discloses an automated bag-breaking and adding system for conveyor belts. When loading bags, workers only need to move the bags to the shelf, and the robotic arm can automatically transfer the bags from the shelf to the conveyor belt. When the bag comes into contact with the cutting blade, the bag can push the cutting blade to slide along the guide rail. Due to the arrangement and shape of the guide rail, the cutting blade will move from the middle of the bag to both sides, thereby cutting the bag into two pieces, and the material inside will spill out, completing the cutting and unloading of the bag. Compared with traditional technology, the bag breaking in this solution is carried out in the bag breaking box, so there will be no dust escaping and polluting the environment and human body, effectively protecting workers. Both the bag loading and bag breaking processes are completed by mechanical equipment, and workers are only responsible for moving the bags to the shelf, thus greatly improving the efficiency of loading and bag breaking.

[0026] To make the technical means, technical features, utility model purpose and technical effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0027] Example 1:

[0028] like Figure 1 and Figure 2 As shown, this embodiment provides an automated bag-breaking and adding system for bags containing material, including a robotic arm 12 and a shelf 11 for holding bags, a bag-breaking box 14 and a conveyor belt 29 placed inside the bag-breaking box 14. One end of the conveyor belt 29 extends from the entrance of the bag-breaking box 14 to the outside of the bag-breaking box 14. A pair of cutting blades 24 are provided inside the bag-breaking box 14. The pair of cutting blades 24 are slidably connected to the bag-breaking box 14 via a guide rail 23. When the bag moves on the conveyor belt 29, it contacts the pair of cutting blades 24 and pushes the pair of cutting blades 24 to slide along the guide rail 23. The cutting blades 24 move horizontally and cut from the middle of the bag to both sides of the bag. A return spring 52 is provided on the bag-breaking box 14 to reset the cutting blades 24.

[0029] Preferably, there are two guide rails 23 on the left and right sides, both of which are arc-shaped or semi-circular and are fixed to the top of the bag breaking box 14 by screws. The guide rails 23 are slidably connected to sliders 53, and a cutting motor is screwed on the sliders 53. The cutting motor drives the cutting blade 24 to rotate. The rotating cutting blade 24 can improve the cutting effect. When the bag comes into contact with the cutting blade 24, the rotating cutting blade 24 can cut the bag instantly. The sliders 53 can support the cutting blade 24 to move along the guide rails 23 when it is pushed by the bag.

[0030] Preferred, such as Figure 6 and Figure 7As shown, one end of the return spring 52 is fixedly connected to the top screw of the bag breaking box 14, and the other end is fixedly connected to the slider 53. The return spring 52 can pull the slider 53 back to the initial position. After the current bag is cut, the bag is also separated from the cutting tool 24 under the action of the conveyor belt 29. At this time, the cutting tool 24 is no longer pushed by the bag. The return spring 52 will pull the cutting tool 24 to move in the opposite direction along the guide rail 23, so as to return to the initial position on the guide rail 23, which is convenient for cutting the next bag.

[0031] Preferred, such as Figure 5 As shown, the conveyor belt 29 includes a perforated mesh 32 for transporting material bags and a chain that drives the perforated mesh 32 to move. The chain is fixed to both sides of the perforated mesh 32 by welding or screws. Metal spikes 51 are welded to the outside of the chain. The cut material bags pass through the perforated mesh 32 and fall into the discharge hopper 28 at the bottom of the conveyor belt 29. Metal detectors can penetrate into the material bags, thereby ensuring that the material bags and the conveyor belt 29 do not move relative to each other.

[0032] Preferred, such as Figure 2 As shown, a first baffle 25 and a second baffle 33 are arranged opposite each other at the outlet of the bag breaking box 14. There is a cut between the first baffle 25 and the second baffle 33 for the waste bag to pass through. After the material bag is cut, the unloaded waste bag will continue to move along the conveyor belt 29. When it moves to the end of the conveyor belt 29, the first baffle 25 and the second baffle 33 block the waste bag, so that the waste bag can only pass through the cut between them. During this process, the waste bag will flip and bend, thereby further dispersing the residual material in the waste bag into the discharge funnel 28, and then the waste bag enters the outlet of the bag breaking box 14.

[0033] Preferably, the first baffle 25 is located on top of the second baffle 33 and is fixedly connected to the bag-breaking box 14 with screws, and the second baffle 33 is fixed to the end of the conveyor belt 29 with screws.

[0034] Preferred, such as Figure 1 and Figure 2As shown, a discharge guide roller 27 is provided at the outlet of the bag breaking box 14. The discharge guide roller 27 is rotatably connected to the bag breaking box 14 through bearings. The discharge guide roller 27 is a right-hand spiral guide roller. The discharge guide roller 27 is driven to rotate by the discharge motor 26. The discharge motor 26 is fixed inside the bag breaking box 14 with screws. A collection box 15 for collecting waste bags is connected to the outlet of the bag breaking box 14. The discharge guide roller 27 discharges the waste bags through the outlet of the bag breaking box 14 into the collection box 15. A roller 21 is provided on the outer side of the bag breaking box 14 near the inlet of the bag breaking box 14. The discharge guide roller 27 can spirally push the waste bags out of the outlet of the bag breaking box 14 through the spiral thrust and collect them through the collection box 15. As for the roller 21, it can spread out and flatten the bag when the bag enters the inlet of the bag breaking box 14, so that the shape of the bag is relatively regular and easier to cut.

[0035] Preferably, the discharge funnel 28 is connected to a mixing unit 16, which is located on the outside of the bag breaking box 14. The mixing unit 16 can mix the materials evenly.

[0036] Preferred, such as Figure 4 As shown, the cutting tool 24 includes a cutting tool connecting rod 41 and a cutting blade 42. One end of the cutting tool connecting rod 41 is fixedly connected to the cutting blade 42, and the other end of the cutting tool connecting rod 41 is fixedly connected to the cutting motor on the same axis. The cutting blade 42 is close to the conveyor belt 29. The cutting blade 42 is placed horizontally and rotates in the horizontal direction. When cutting, it moves along the horizontal plane. When cutting, the cutting blade 42 can cut close to the bottom of the bag in the vertical direction, which is closer to the bottom of the bag. This horizontal cutting of the bag close to the bottom of the bag ensures that the material can be completely spilled out during the cutting.

[0037] Preferred, such as Figure 3 As shown, conveyor belt covers 43 are fixedly installed on both sides of the conveyor belt 29 with screws, and a conveyor belt support frame 35 is fixedly connected to the bottom of the conveyor belt 29 with screws. The conveyor belt support frame 35 is fixedly mounted on the conveyor belt fixed platform 34 with screws. The conveyor belt fixed platform 34 is supported by support legs 37. The conveyor belt 29 is connected to a conveyor motor 36 and a conveyor gearbox 31. The motor drives the chain to move after being reduced in speed by the conveyor gearbox 31.

[0038] The robotic arm 12 is equipped with an automated control terminal, an intelligent recognition device, and a rotating base 13. The rotating base 13 can control the rotation direction of the robotic arm to achieve 360° full-angle rotation, enabling the robotic arm to grasp materials from a larger range.

[0039] The robotic arm 12 is a gripping robot with hydraulically driven claws that can grip bagged materials placed on the bag rack. With the cooperation of intelligent identification devices and intelligent control terminals, the robotic arm 12 can automatically identify the materials and their status, achieving an integrated function of automatic unloading and loading.

[0040] The intelligent identification system accurately determines the material placement status on the bag rack using weight detection sensors on the rack 11. Visual inspection via a high-definition camera allows for precise material grabbing within a system-defined range. Infrared sensors at the inlet and outlet of the conveyor belt 29 accurately identify the material's position on the belt; any deviation will be automatically detected and an alarm will sound.

[0041] The control system on this equipment consists of two parts: the overall control module and the automated robotic arm 12 control module. The overall control module, located at the rear, allows for remote control of the entire system's start and stop, real-time monitoring of various data from the intelligent recognition system, and real-time adjustments based on the situation. The automated robotic arm 12 control module, installed near the robotic arm 12, allows for real-time modification of the robotic arm 12's operating program via a built-in program. It also allows for manual operation of the robotic arm 12 in special circumstances, enabling it to grip the bag from the shelf and place it onto the conveyor belt 29 according to a pre-set program.

[0042] The bag-breaking box 14 is equipped with a dust removal component, which can prevent a large amount of dust from being generated when the bag breaks and filling the processing environment, thus reducing dust pollution and further protecting the health of the operators. The material release process takes place inside the box, effectively ensuring the cleanliness of the production environment.

[0043] In use, when loading the bag, the worker only needs to move the bag onto the shelf 11. The robotic arm 12 can automatically transfer the bag from the shelf 11 to the conveyor belt 29. When the bag comes into contact with the cutting blade 24, the bag can push the cutting blade 24 to slide along the guide rail 23. Due to the arrangement and shape of the guide rail 23, the cutting blade 24 will move from the middle of the bag to both sides, thereby cutting the bag into two pieces, and the material inside will spill out, completing the cutting and unloading of the bag. Compared with traditional technology, the bag breaking in this solution is carried out in the bag breaking box 14, so there will be no dust coming out to pollute the environment and human body, effectively protecting the workers. Both the loading and breaking of the bag are completed by mechanical equipment. The worker is only responsible for moving the bag onto the shelf 11, so the loading and breaking efficiency is greatly improved.

[0044] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent changes and modifications made in accordance with the scope of the claims of this utility model should fall within the technical scope of this utility model.
