Description

Technical Field

[0001] This utility model relates to the field of paper bag production, specifically to a paper bag dust collector. Background Technology

[0002] In modern industrial production, paper bags are a common packaging material widely used in food, pharmaceuticals, daily necessities, and many other fields. However, during the production, transportation, and storage of paper bags, various impurities, such as dust, paper scraps, and fibers, often adhere to their surface. These impurities not only affect the appearance of the paper bags but may also contaminate the packaged products. This is especially true for products with high hygiene requirements, such as food and pharmaceuticals, where the presence of impurities can pose serious quality risks.

[0003] Traditional paper bag dust removal methods have many shortcomings. For example, some simple manual wiping methods are inefficient and cannot meet the needs of large-scale production. Moreover, the wiping process can easily damage the surface of the paper bags. Some dust removal equipment that uses a single blowing device can only blow away some of the surface debris. It is not effective in removing some debris with strong adsorption, and the blown debris can easily be dispersed again in the workshop, causing secondary pollution.

[0004] In conclusion, there is an urgent need in the market for a high-efficiency, comprehensive, and environmentally friendly dust removal device for paper bags that can effectively remove various impurities from the surface of paper bags, while also possessing good impurity collection and processing capabilities, in order to meet the requirements of modern industry for paper bag quality and production environment. Utility Model Content

[0005] In view of this, the present invention provides a paper bag dust collector, which effectively removes impurities from the surface of paper bags through the rubber roller shaft, electrostatic roller shaft and gas impurity removal component in the impurity removal mechanism, and collects the impurities at the same time, so as to prevent the blown impurities from easily drifting again in the workshop and causing secondary pollution.

[0006] To solve the above-mentioned technical problems, this utility model provides a paper bag dust collector, including a mounting base frame, a belt conveyor for conveying paper bags is installed in the mounting base frame, and a dust removal mechanism for removing impurities from the paper bags is installed on the belt conveyor; the dust removal mechanism includes a housing set on the belt conveyor, and a rubber roller shaft and an electrostatic roller shaft are rotatably arranged inside the housing via rotating shafts, and the two are driven by a drive source respectively; the dust removal mechanism also includes a gas dust removal component disposed between the rubber roller shaft and the electrostatic roller shaft.

[0007] In other words, a belt conveyor is used to transport paper bags, while a cleaning mechanism is used to remove impurities from the paper bags. Specifically, the rotation of rubber rollers and electrostatic rollers allows for physical contact and electrostatic adsorption on the surface of the paper bags to remove impurities. Furthermore, a gas removal component is used to remove the adsorbed impurities from the paper bags. By combining these multiple methods, impurities on the paper bags can be removed more comprehensively and efficiently, thus improving the cleanliness of the paper bags.

[0008] The gas impurity removal assembly includes a gas circulation box installed inside the housing. The gas circulation box has an air blowing channel, an air intake channel, and a collection chamber. A partition is provided between the air blowing channel and the air intake channel, and a compression zone that can accelerate gas flow is formed between the gas outlet of the air blowing channel and the partition.

[0009] That is, a gas circulation and impurity removal system is formed by opening an air blowing channel, an air intake channel and a collection chamber in the gas circulation box. The gas flow rate is increased by using a geometrically shaped compression zone, so that the gas blown out of the air blowing channel has a greater impact force, which more effectively blows up the impurities on the paper bag. Then, the impurities are sucked into the collection chamber through the air intake channel, thereby improving the efficiency of gas impurity removal.

[0010] The collection chamber is equipped with a slidable storage box for collecting miscellaneous items. The side plate of the storage box has several air holes for gas circulation. The top of the storage box is equipped with a sealing cover for sealing the gas circulation box. Handles are symmetrically arranged on the sealing cover.

[0011] In other words, a collection box is slidably installed in the collection chamber to collect debris. The air vents on the side of the collection box ensure airflow, allowing debris to smoothly enter the collection box with the airflow. The gas circulation box is sealed by a sealing cover to prevent leakage of debris. Furthermore, the symmetrical handles installed on the top of the sealing cover allow operators to easily remove the collection box and clean the debris inside, improving the maintainability of the equipment.

[0012] A gas supply module for providing gas source is provided on one side of the gas circulation box. The gas supply module includes a gas tank, a gas pump and a gas nozzle. The gas tank is fixedly installed inside the housing by a gas tank mounting bracket and is located on one side of the gas circulation box. Several gas guide pipes are connected to the bottom of the gas tank. The gas guide pipes pass through the gas circulation box and are set at the gas inlet of the blowing channel. The gas nozzle is set at the end of the gas guide pipe.

[0013] That is, the gas supply module provides a gas source for the gas impurity removal component, the gas tank is used to transport the gas to the blowing channel through the gas pipe, and the gas is blown out of the blowing channel in a concentrated manner through the gas nozzle, so as to ensure that the blowing channel has sufficient gas flow and pressure, thereby improving the gas impurity removal effect. Moreover, the gas tank is fixed inside the housing by the gas tank mounting bracket to ensure the stability of the gas supply module.

[0014] There are two air pumps, which are fixedly mounted on the side plate of the housing via an extension platform, and the two air pumps are connected to the air tank via a T-joint.

[0015] That is, two air pumps are connected to the gas tank through a three-way connector, which enables them to provide greater gas pressure and flow rate, ensuring that there is sufficient gas supply inside the gas tank and meeting the gas source requirements of the gas impurity removal component, thereby improving the efficiency and stability of gas impurity removal.

[0016] Both the rubber roller and the electrostatic roller are equipped with scrapers on one side for removing debris from the roller. The bottom of the scraper is slidably equipped with a pull-out box for collecting debris via a groove. The outer side plate of the pull-out box is equipped with a handle.

[0017] In other words, the scraper can promptly remove debris adsorbed on the rubber roller and electrostatic roller, preventing the accumulation of debris from affecting the working effect of the roller. The pull-out box makes it easy to collect the debris removed by the scraper. The pull-out box can be easily pulled out with the handle for cleaning, ensuring the cleanliness of the roller and extending its service life.

[0018] The drive source includes a slow-speed motor located on the outside of the housing for driving the rotation of the shaft.

[0019] That is, the slow-speed motor can provide a stable and appropriate speed, so that the rubber roller shaft and the electrostatic roller shaft can operate at an appropriate speed, ensuring the normal operation of the impurity removal mechanism. Furthermore, the slow-speed operation can better match the conveying speed of the belt conveyor, thereby improving the impurity removal effect.

[0020] The mounting base is equipped with a stress plate to increase friction, which is located at the bottom of the upper belt of the belt conveyor.

[0021] That is, by setting the force plate at the bottom of the upper belt, the friction between the paper bag and the belt, rubber roller shaft, electrostatic roller shaft and gas impurity removal component after the paper bag enters the housing is increased, ensuring the stability of the paper bag during the conveying process, preventing the paper bag from sliding or deviating during the conveying process, and thus enabling the impurity removal mechanism to perform impurity removal operation on the paper bag more accurately, thereby improving the working accuracy and stability of the equipment.

[0022] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0023] 1. Rubber rollers can remove larger impurities from the surface of paper bags through physical contact; electrostatic rollers use electrostatic adsorption to adsorb tiny dust and impurities on the paper bags; gas removal components blow up and collect impurities from the surface of the paper bags by blowing and sucking air. Through the coordinated work of multiple removal methods, impurities on paper bags can be removed comprehensively and efficiently, effectively improving the cleanliness and quality of paper bags and meeting higher production standards.

[0024] 2. The special internal structure of the gas circulation box, including the blowing channel, suction channel, and collection chamber, as well as the compression zone formed by the outlet of the blowing channel and the partition, accelerates gas flow and more effectively blows away debris from the surface of the paper bag. Simultaneously, the debris is sucked into the collection box within the collection chamber by the airflow. The collection box is slidable and features a sealing cover and handle for easy cleaning of the collected debris, ensuring both effective debris removal and convenient maintenance and operation.

[0025] 3. Scrapers installed on one side of the rubber roller shaft and electrostatic roller shaft can promptly remove debris adsorbed on the roller shaft, preventing debris accumulation from affecting the cleaning effect. The pull-out box at the bottom of the scraper is slidably installed via a groove, and the outer side plate has a handle for easy removal and cleaning of collected debris. This design makes cleaning and maintenance of the equipment more convenient and faster, reduces equipment downtime, lowers maintenance costs, and improves production efficiency.

[0026] 4. By placing the force plate at the bottom of the upper belt, the friction between the paper bag and the belt, rubber roller shaft, electrostatic roller shaft and gas impurity removal component is increased after the paper bag enters the housing. This ensures the stability of the paper bag during the conveying process, prevents the paper bag from sliding or deviating during the conveying process, and enables the impurity removal mechanism to perform impurity removal operation on the paper bag more accurately, thereby improving the working accuracy and stability of the equipment.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-6 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0035] like Figures 1-6 As shown: This embodiment provides a paper bag dust collector, including a mounting base 1. The mounting base 1 is equipped with a belt conveyor 2 for conveying paper bags. A dust removal mechanism 3 for removing impurities from the paper bags is installed on the belt conveyor 2. The dust removal mechanism 3 includes a housing 31 disposed on the belt conveyor 2. A rubber roller shaft 33 and an electrostatic roller shaft 34 are rotatably disposed inside the housing 31 via a rotating shaft 32. Both are driven by a drive source 35. The dust removal mechanism 3 also includes a gas dust removal component 40 disposed between the rubber roller shaft 33 and the electrostatic roller shaft 34.

[0036] In practical applications, the mounting base 1 serves as the fundamental support structure for the entire paper bag dust collector, providing a stable mounting platform for the belt conveyor 2 and the dust removal mechanism 3. After the belt conveyor 2 is started, the paper bags are placed on the conveyor belt and transported smoothly. When the paper bags pass the dust removal mechanism 3, the drive source 35 drives the rubber roller shaft 33 and the electrostatic roller shaft 34 to begin rotating. During rotation, the rubber roller shaft 33 contacts the surface of the paper bag, using friction to remove larger, loosely attached debris. The electrostatic roller shaft 34 utilizes its electrostatic adsorption properties to adsorb dust, hair, and other small debris from the surface of the paper bag. Simultaneously, the gas dust removal component 40 begins operation to assist in removing debris from the paper bags.

[0037] The combination of multiple methods improves the efficiency and effectiveness of paper bag cleaning. The rubber roller shaft 33, the electrostatic roller shaft 34 and the gas cleaning component 40 work together to remove debris from paper bags from different angles and of different types. Compared with a single cleaning method, it can clean paper bags more comprehensively and thoroughly, meeting the cleanliness requirements of different customers.

[0038] like Figure 4 As shown: The gas impurity removal assembly 40 includes a gas circulation box 41 installed inside the housing 31. The gas circulation box 41 has an air blowing channel 42, an intake channel 43, and a collection chamber 44. A partition 45 is provided between the air blowing channel 42 and the intake channel 43, and a compression zone is formed between the gas outlet of the air blowing channel 42 and the partition 45 to accelerate gas flow. After the gas circulation box 41 is installed inside the housing 31, the gas supply module 50 delivers gas to the air blowing channel 42. The gas flows in the air blowing channel 42. When it reaches the compression zone between the gas outlet of the air blowing channel 42 and the partition 45, the gas flow rate increases due to the sudden narrowing of the channel space. The high-speed airflow is ejected from the compression zone and blown towards the passing paper bag, blowing up impurities on the surface of the paper bag. The blown-up impurities enter the intake channel 43 with the airflow and are then guided to the collection chamber 44.

[0039] The compression zone cleverly utilizes fluid dynamics principles to accelerate gas flow. The high-speed airflow generates greater impact force, more effectively blowing away debris from the paper bag and improving the removal efficiency. Furthermore, the gas circulation box 41 integrates the functions of blowing, sucking, and collecting debris, forming a relatively closed gas circulation system. This reduces the possibility of debris spreading into the surrounding environment, making it both environmentally friendly and improving the concentration of debris removal.

[0040] like Figure 2 and Figure 4 As shown: A collection box 46 for collecting miscellaneous items is slidably provided in the collection chamber 44. The side plate of the collection box 46 has several air holes 47 for gas circulation. The top of the collection box 46 is provided with a sealing cover 48 for sealing the gas circulation box 41. Handles 49 are symmetrically arranged on the sealing cover 48.

[0041] When debris enters the collection chamber 44 with the airflow, it is trapped inside the storage box 46. The gas is then discharged through the vent 47 on the side plate of the storage box 46, continuing to participate in the gas circulation. As the usage time increases, the amount of debris inside the storage box 46 gradually increases. When cleaning is required, the operator pulls the storage box 46 out of the collection chamber 44 by grasping the handle 49 on the sealing cover 48, emptys the debris inside, pushes the storage box 46 back into the collection chamber 44, closes the sealing cover 48, and continues normal operation.

[0042] The sliding storage box 46 makes cleaning up debris very convenient, eliminating the need for complicated disassembly. The vent 47 ensures smooth gas flow, maintaining the normal operation of the gas circulation system. The sealing cover 48 prevents debris and gas leakage, maintaining the airtightness of the collection chamber 44 and improving the stability and reliability of the entire gas removal assembly 40.

[0043] like Figure 1 , Figure 4 and Figure 5 As shown: A gas supply module 50 for providing gas source is provided on one side of the gas circulation box 41. The gas supply module 50 includes a gas tank 501, a gas pump 52 and a gas nozzle 503. The gas tank 501 is fixedly installed inside the housing 31 by a gas tank 501 mounting bracket and is located on one side of the gas circulation box 41. Several gas guide pipes 505 are connected to the bottom of the gas tank 501. The gas guide pipes 505 pass through the gas circulation box 41 and are set at the gas inlet of the blowing channel 42. The gas nozzle 503 is set at the end of the gas guide pipe 505.

[0044] Gas cylinder 501 is securely fixed inside housing 31 by a mounting bracket, located on one side of gas circulation box 41. Two air pumps 52 operate simultaneously, delivering gas to gas cylinder 501 for storage via tee connector 507. Gas in gas cylinder 501 enters blowing channel 42 through air guide pipe 505 connected to the bottom and air nozzle 503. The design of air nozzle 503 allows gas to enter blowing channel 42 more concentratedly and evenly, ensuring effective blowing.

[0045] The air supply module 50 provides a stable and sufficient air source for the gas impurity removal component 40. The storage function of the air tank 501 ensures a continuous supply of gas to the blowing channel 42 even during the downtime of the air pump 52, preventing interruptions in the gas supply. The two air pumps 52 increase the pressure and flow rate of the air supply, ensuring sufficient gas pressure within the blowing channel 42 to form a high-speed airflow. The use of the air nozzle 503 improves the gas utilization efficiency, allowing the gas to act more precisely on the paper bag, further enhancing the impurity removal effect.

[0046] like Figure 1 As shown: There are two air pumps 52, which are fixedly mounted on the side plate of the housing 31 via an extension platform 506, and the two air pumps 52 are connected to the air tank 501 via a three-way connector 507. During equipment operation, the two air pumps 52 start simultaneously, rapidly and in large quantities delivering external gas to the air tank 501. The gas pressure inside the air tank 501 continuously increases as the air pumps 52 operate, providing a continuous and stable high-pressure gas supply to the air blowing channel 42.

[0047] The coordinated operation of the two air pumps 52 significantly increases the air supply capacity. Compared to a single air pump 52, the dual air pumps 52 can provide a larger gas flow rate and higher pressure, resulting in a faster gas flow rate and stronger impact force within the blowing channel 42. This not only improves the impurity removal effect of the gas impurity removal component 40, but also adapts to the impurity removal needs of paper bags of different specifications and materials, enhancing the versatility and adaptability of the equipment.

[0048] like Figure 4 and Figure 6 As shown: Both the rubber roller shaft 33 and the electrostatic roller shaft 34 are equipped with scrapers 36 on one side for removing debris from the roller shafts. A pull-out box 38 for collecting debris is slidably mounted on the bottom of the scraper 36 via a groove 37. A handle 39 is provided on the outer side plate of the pull-out box 38. During the rotation of the rubber roller shaft 33 and the electrostatic roller shaft 34, the scraper 36 remains in contact with the roller shaft surface. As the roller shafts rotate, the scraper 36 scrapes off the debris adsorbed on the roller shaft surface. The scraped debris falls along the scraper 36 into the pull-out box 38 at the bottom. When the debris in the pull-out box 38 accumulates to a certain level, the operator pulls the handle 39 on the outer side plate of the pull-out box 38 to remove it from the groove 37, empty the debris, and then pushes it back into its original position.

[0049] The scraper 36 effectively solves the problem of debris accumulation on the roller surface. If the debris on the roller surface is not cleaned in time, it will affect the removal efficiency and service life of the roller. The pull-out box 38 facilitates the collection and cleaning of debris, preventing debris from accumulating inside the equipment and ensuring the normal operation of the equipment and the stability of the removal efficiency.

[0050] like Figure 1 and Figure 3 As shown, the drive source 35 includes a slow-speed motor 351 disposed outside the housing 31 for driving the rotation of the rotating shaft 32. After the slow-speed motor 351 is started, the motor drives the rotating shaft 32 to rotate at a suitable speed, thereby driving the rubber roller shaft 33 and the electrostatic roller shaft 34 to rotate. The operator can control the rotation speed of the rubber roller shaft 33 and the electrostatic roller shaft 34 by adjusting the speed of the slow-speed motor 351 according to the actual situation such as the material of the paper bag, the type and quantity of debris.

[0051] The use of the slow-speed motor 351 allows for precise control of the rotational speeds of the rubber roller shaft 33 and the electrostatic roller shaft 34. Different paper bag materials and types of debris require different roller speeds to achieve optimal debris removal. By adjusting the speed of the slow-speed motor 351, it can flexibly adapt to various working scenarios, improving the debris removal quality and efficiency of the equipment, while also extending the service life of the roller shafts and the motor.

[0052] like Figure 4As shown: A force-bearing plate 21 for increasing friction is installed inside the mounting base 1. The force-bearing plate 21 is located at the bottom of the upper belt of the belt conveyor 2. When the belt conveyor 2 is running and the paper bag is placed on the belt and conveyed, the force-bearing plate 21 provides an upward support force to the upper belt, increasing the friction between the belt, the electrostatic roller shaft 34 and the rubber roller shaft 33 and the paper bag. This makes the paper bag more stable during the conveying process and prevents it from easily slipping or shifting.

[0053] The force plate 21 ensures the stability of the paper bags during the conveying process. Stable conveying ensures that the paper bags pass accurately through the impurity removal mechanism 3, avoiding incomplete impurity removal due to slippage or deviation of the paper bags. At the same time, the increased friction also helps to improve the conveying efficiency of the belt conveyor 2, reduces the jamming of paper bags during the conveying process, and improves the overall working efficiency and stability of the paper bag dust collector.

[0054] The method of using this utility model is as follows: Place the paper bag that needs to be dusted on the upper belt of the belt conveyor 2. The paper bag is conveyed by the belt to the bottom of the impurity removal mechanism 3. When the paper bag passes the rubber roller 33, the rubber roller 33 removes larger particles of impurities from the surface of the paper bag through friction with the surface of the paper bag. Then the paper bag is conveyed by the belt to the bottom of the gas impurity removal component 40. After passing through the compression area to accelerate the airflow, the high-speed airflow blows towards the paper bag, blowing up the impurities on the paper bag. The impurities are carried by the airflow through the suction channel 43 into the collection box 46 of the collection chamber 44. The paper bag will be conveyed by the belt to the electrostatic roller 34. Using electrostatic adsorption, the dust and other small impurities on the surface of the paper bag are adsorbed. During the operation of the rubber roller 33 and the electrostatic roller 34, the scraper 36 will continuously scrape off the impurities adsorbed on the surface of the roller. The scraped impurities fall into the pull-out box 38 at the bottom.

[0055] After the equipment has been running for a certain period of time, the storage box 46 and the pull-out box 38 should be pulled out using handle 39 and pull handle 49 respectively to clean out the debris inside.

[0056] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0057] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
