Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and in particular to a dust bar device suitable for cleaning equipment. Background Technology

[0002] Opening and cleaning equipment is a key pretreatment device in textile machinery. Its main function is to separate and remove impurities (such as seed dust, short fibers, and micro dust) from fiber raw materials, while assisting in the opening, mixing, and conveying of fibers. As an important piece of equipment in the cleaning and carding combined machine, opening and cleaning equipment is generally divided into cotton openers that remove large impurities and cotton cleaners that remove small impurities and micro dust.

[0003] After the fibers enter the cleaning equipment, they are separated from impurities by impacting the dust bars. As the main impurity removal mechanism in the cleaning equipment, the performance of the dust bars directly determines the impurity removal efficiency of the cleaning equipment and even the technical specifications of the entire cleaning and combing machine.

[0004] Dust bars will wear out after a period of use and fail to meet the set process spacing requirements, thus significantly limiting the impurity removal effect. Therefore, they need to be replaced frequently. However, the existing dust bar devices have a complex structure, and maintenance and replacement require disassembling multiple parts and recalibrating, which is time-consuming and labor-intensive.

[0005] Therefore, there are still shortcomings and deficiencies in the existing technology. How to provide a dust bar device that is easy to maintain and suitable for cleaning equipment is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] The purpose of this utility model is to provide a dust bar device suitable for cleaning equipment, which solves the technical problems of existing dust bar devices having a complex structure and requiring the disassembly of multiple parts and recalibration during maintenance and replacement, which is time-consuming and labor-intensive.

[0007] To achieve the above objectives, this utility model provides a dust bar device suitable for cleaning equipment, comprising:

[0008] A dust bar assembly, comprising a base and a dust removal component, wherein the base has a triangular cross-section, the dust removal component is bonded to one side of the base and fixed by fasteners, and the dust removal component is used to impact fibers to separate impurities;

[0009] An adjustment mechanism is used to change the angle of the dust removal component. The adjustment mechanism includes an adjustment handle, a cam assembly, and an adjustment plate, and the adjustment plate is connected to the base.

[0010] When the adjustment handle is rotated, the adjustment plate can be driven to swing through the cam assembly, thereby changing the angle of the dust removal component and thus changing the impact angle between the dust removal component and the fiber.

[0011] Preferably, the cam assembly includes:

[0012] A camshaft is fixedly connected to the adjusting handle, and rotating the adjusting handle drives the camshaft to rotate.

[0013] A cam, fixedly mounted on the camshaft, has its profile constructed as an eccentric arc or an involute. The adjusting plate contacts the cam, which is used to convert the rotational motion of the adjusting handle into the oscillation of the adjusting plate.

[0014] Preferably, the base has mounting holes at both ends, which are used to fix the base to the cleaning equipment by bolts.

[0015] Preferably, when it is necessary to change the angle of the dust removal component, the bolt serves as the pivot center for the swing of the adjusting plate.

[0016] Preferably, the adjusting plate has a wear-resistant block on the side near the cam, and the wear-resistant block is in contact with the cam.

[0017] Preferably, the dust bar assembly further includes a fixing rod disposed at one end of the base, the fixing rod being fixedly connected to the base.

[0018] Preferably, the fixing rod is connected to the adjusting plate by fixing screws.

[0019] Preferably, the dust removal component is bonded to the base with sealant.

[0020] Preferably, the fastener is a detachable rivet.

[0021] Compared to the aforementioned background technology, the dust bar device for cleaning equipment provided by this utility model has a dust removal component bonded to one side of the base and fixed with fasteners to ensure connection strength and improve structural stability. When the dust removal component is worn or damaged, it can be removed from the base and replaced with a new one, without the need to replace the entire dust bar assembly. This significantly reduces maintenance costs and makes operation more convenient. By turning the adjustment handle, the adjustment plate can be swung through the cam assembly to change the angle of the dust removal component, thereby adjusting the impact angle between the dust removal component and the fiber and controlling the impact force and the amount of debris falling off.

[0028] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] This utility model provides a dust bar device suitable for cleaning equipment. After the dust removal component 11 is worn or damaged, the dust removal component 11 can be removed from the base 10 and replaced with a new dust removal component 11. There is no need to replace the entire dust bar assembly, making maintenance convenient.

[0031] Please refer to this as well. Figures 1 to 4 The dust bar device for cleaning equipment provided by this utility model includes a dust bar assembly and an adjustment mechanism.

[0032] The dust bar assembly includes a base 10 and a dust removal component 11. The base 10 has a triangular cross-section. The dust removal component 11 is bonded to one side of the base 10 and fixed by a fastener 12. The dust removal component 11 is used to impact the fibers to separate impurities.

[0033] Specifically, the base 10 has a right-angled triangular cross-section, and the dust collector 11 is located on the inclined surface of the base 10. The base 10 is made of aluminum profile, which is lightweight and high-strength. Due to the high plasticity of aluminum profile, the base 10 is easy to process and shape. The dust collector 11 has a plate-like structure. The dust collector 11 is made of 40Cr material and has undergone quenching and tempering treatment, resulting in higher strength and hardness, better wear resistance, and extended service life.

[0034] The dust collector 11 is bonded to one side of the base 10 and secured by fasteners 12 to ensure connection strength and improve structural stability. During use, the dust collector 11 impacts the fibers to separate impurities. When the dust collector 11 is worn or damaged, it can be removed from the base 10 and replaced with a new one. There is no need to replace the entire dust bar assembly, making maintenance convenient and operation easy.

[0035] The adjustment mechanism is used to change the angle of the dust collector 11. The adjustment mechanism includes an adjustment handle 20, a cam assembly and an adjustment plate 21. The adjustment handle 20 is connected to the cam assembly, the cam assembly is connected to the adjustment plate 21, and the adjustment plate 21 is connected to the base 10.

[0036] When the adjustment handle 20 is rotated, the adjustment plate 21 can be driven to swing through the cam assembly, thereby changing the angle of the dust collector 11 and changing the impact angle between the dust collector 11 and the fiber.

[0037] The impact force and the amount of debris can be controlled by changing the impact angle between the dust collector 11 and the fiber. When it is necessary to change the impact angle during use, the adjustment handle 20 is turned, and the adjustment plate 21 is swung by the cam assembly to change the angle of the dust collector 11, thereby adjusting the impact angle between the dust collector 11 and the fiber.

[0038] In some embodiments, the cam assembly includes a camshaft and a cam.

[0039] The camshaft is fixedly connected to the adjusting handle 20, and rotating the adjusting handle 20 drives the camshaft to rotate. Figure 1 Taking the horizontal and vertical directions as an example, in this embodiment, the axis of the camshaft is set in the horizontal direction, and the adjusting handle 20 is fixedly connected to the right end of the camshaft. When in use, the adjusting handle 20 is rotated in the vertical plane, which drives the camshaft to rotate in the vertical plane.

[0040] The cam is fixed to the camshaft, and its profile is constructed as an eccentric arc or involute. The adjusting plate 21 contacts the cam, which converts the rotational motion of the adjusting handle 20 into the oscillation of the adjusting plate 21. The camshaft rotates in the vertical plane, causing the cam to rotate in the vertical plane. As the cam rotates, because the outer profile of the cam contacts the adjusting plate 21, the cam can drive the adjusting plate to oscillate in the vertical plane. The adjusting plate 21 is connected to the base 10, thereby causing the base 10 and the dust collector 11 to oscillate in the vertical plane.

[0041] When changing the impact angle between the dust collector 11 and the fiber, rotate the adjusting handle 20. The adjusting handle 20 drives the camshaft to rotate, which in turn drives the cam on the camshaft to rotate. As the cam rotates, its contour pushes the adjusting plate 21, forcing the adjusting plate 21 to swing. The adjusting plate 21 drives the base 10 and the dust collector 11 to swing, changing the angle of the dust collector 11.

[0042] In some embodiments, please refer to the following: Figures 1 to 4 The base 10 has mounting holes 101 at both ends, which are used to fix the base 10 to the cleaning equipment by bolts 30. In this embodiment, the mounting holes 101 are smooth holes rather than threaded holes. During installation, the bolts 30 pass through the side wall of the cleaning equipment and the mounting holes 101 on the base 10 and are locked in place by nuts.

[0043] Based on the above embodiment, when it is necessary to change the angle of the dust removal component 11, the bolt 30 serves as the pivot center for the swinging of the adjusting plate 21. Figure 1 The horizontal and vertical directions are explained in the following. The axis of bolt 30 is set in the horizontal direction. When the cam pushes the adjusting plate 21, the adjusting plate 21 swings in the vertical plane with the horizontally set bolt 30 as the axis of rotation.

[0044] Specifically, when it is necessary to change the impact angle between the dust collector 11 and the fiber, by loosening the nut, the bolt 30 can serve as the pivot center for the swing of the adjusting plate 21. By rotating the adjusting handle 20, the profile of the cam pushes the adjusting plate 21, allowing the adjusting plate 21 to rotate and swing around the bolt 30, thereby changing the angle between the base 10 and the dust collector 11, and thus adjusting the impact angle between the dust collector 11 and the fiber. After adjustment, the nut is tightened to secure the connection between the base 10 and the cleaning equipment, ensuring the stability of the connection and locking the base 10 to prevent swaying between the base 10 and the adjusting plate 21, thus ensuring stability.

[0045] It is understood that in other embodiments, the mounting hole 101 can also be a threaded hole. In this case, the bolt 30 passes through the side wall of the cleaning equipment and is threadedly connected to the mounting hole 101 on the base 10. During adjustment, the bolt 30 can be loosened. The bolt 30 serves as the pivot center for the swing of the adjustment plate 21. After adjustment, the bolt 30 is tightened again.

[0046] In some embodiments, the adjusting plate 21 is provided with a wear-resistant block on the side near the cam, and the wear-resistant block contacts the cam. The wear-resistant block is made of a highly wear-resistant material. By providing the wear-resistant block during the process of the cam pushing the adjusting plate 21 to swing, the rapid wear caused by direct contact can be avoided, thus extending the service life.

[0047] In some embodiments, please refer to the following: Figures 1 to 3 The dust rod assembly also includes a fixing rod 13 located at one end of the base 10, and the fixing rod 13 is fixedly connected to the base 10. In this embodiment, the fixing rod 13 is made of aluminum profile, and the fixing rod 13 and the base 10 can be manufactured as a whole through an integral molding process to enhance the overall structural integrity.

[0048] In some embodiments, please refer to the following: Figures 1 to 3 The fixing rod 13 is connected to the adjusting plate 21 by the fixing screw 31. The fixing rod 13 is connected to the adjusting plate 21 by the fixing screw 31, so that when the adjusting handle 20 is turned, the adjusting plate 21 swings, and the adjusting plate 21 drives the base 10 and the dust removal component 11 to swing through the fixing rod 13.

[0049] In some embodiments, the dust removal component 11 is bonded to the base 10 with sealant.

[0050] In some embodiments, the fastener 12 is a detachable rivet so that the dust collector 11 can be quickly replaced during maintenance.

[0051] Optionally, in some embodiments, such as Figure 4 As shown, the base 10 is provided with a through hole 102. By providing the through hole 102, the weight of the base 10 can be reduced, materials can be saved, and costs can be reduced.

[0052] Optionally, in some embodiments, an angle sensor may also be installed on the adjustment plate 21. During the adjustment of the angle of the dust removal component 11, the angle sensor detects the change in the angle of the adjustment plate 21 so as to adjust the angle of the dust removal component 11 to the ideal value and ensure the accuracy of the adjusted angle.

[0053] The specific usage process of the dust bar device for cleaning equipment provided by this utility model is as follows:

[0054] First, the dust bar device is installed in the cleaning equipment. When in use, the dust removal component 11 is used to separate impurities by impact with the fibers. When the dust removal component 11 is worn or damaged, the dust removal component 11 is removed from the base 10 and a new dust removal component 11 is installed. There is no need to replace the entire dust bar assembly. It is easy to maintain, convenient to operate, and has low maintenance costs.

[0055] When it is necessary to control the impact force and the amount of debris by changing the impact angle between the dust collector 11 and the fiber, the bolt 30 that installs the base 10 in the cleaning equipment is loosened. The bolt 30 can then serve as the pivot center for the swing of the adjusting plate 21. When the adjusting handle 20 is rotated, the profile of the cam pushes the adjusting plate 21, allowing the adjusting plate 21 to rotate and swing around the bolt 30, thereby changing the angle between the base 10 and the dust collector 11 and adjusting the impact angle between the dust collector 11 and the fiber.

[0056] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0057] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
