Description

Technical Field

[0001] This application relates to the field of workpiece processing technology, and more specifically, to an air blowing device and a winding device. Background Technology

[0002] To reduce the risk of wrinkling during workpiece machining, air holes can be installed on the air pipe of the air blowing device. Air is blown through these holes onto the workpiece to be machined, keeping it flat and reducing the risk of wrinkling. However, airflow directed towards the sides of the workpiece during blowing can easily affect it and cause wrinkles. A common method is to block the air holes that direct the airflow towards the sides of the workpiece to reduce its impact. However, when changing workpiece models, the length of the area requiring blowing changes, and the blocked air pipe is difficult to adapt to different production needs, resulting in low compatibility and increased manufacturing costs. Utility Model Content

[0003] This application provides an air blowing device and a winding equipment, which can reduce the processing cost of workpieces.

[0004] In a first aspect, embodiments of this application provide an air blowing device, including an air pipe and a blocking member; the air pipe extends along a first direction and is provided with a plurality of air holes, which are spaced apart along the first direction; the blocking member is adjustablely disposed on the air pipe along the first direction and is configured to block a portion of the air holes.

[0005] In the above technical solution, the air pipe can blow air outward through multiple air holes spaced apart along the first direction. The shielding member can block some of the air holes, specifically those that direct airflow towards the side of the workpiece along the first direction, thereby reducing the impact of the airflow from those holes on the workpiece. By making the position of the shielding member adjustable along the first direction, its position can be adjusted according to the dimensions of the workpiece along the first direction, ensuring that the shielding member can block the air holes that direct airflow towards the side of the workpiece. This allows the blowing device to be applicable to workpieces of various sizes, improving its compatibility and reducing workpiece processing costs.

[0006] In some embodiments, the air blowing device further includes a locking member configured to unlockably lock the shielding member to the air pipe. By providing the locking member, on the one hand, the locking member can reduce the risk of the shielding member falling off and affecting the workpiece processing; on the other hand, the locking member can lock the shielding member to the air pipe, thereby fixing the position of the shielding member, making the shielding member more stable in blocking the air hole, and improving the processing stability of the workpiece.

[0007] In some embodiments, the blocking member includes a collar and a blocking portion; the collar is movably sleeved on the air pipe along a first direction; the blocking portion is connected to the collar, and the collar is provided with the blocking portion at at least one end along the first direction, the blocking portion being configured to block at least one air hole; wherein, a locking member is configured to unlockably lock the collar to the air pipe. In this way, the blocking portion can move with the collar, and the locking member can lock the collar to the air pipe to fix the position of the blocking portion, making the position of the blocking member more stable and reducing the risk of displacement of the blocking member during workpiece processing.

[0008] In some embodiments, the collar has an inner circumferential surface surrounding the trachea, and the collar is provided with a threaded hole, one end of which extends to the inner circumferential surface. A locking member is screwed into the threaded hole. In this way, the locking member can pass through the inner circumferential surface and abut against the wall of the trachea, thereby fixing the collar and the trachea, and thus securing the trachea and the shielding member.

[0009] In some embodiments, the shielding member further includes a shielding ring sleeved on the collar, the shielding ring covering at least a portion of the threaded hole. By providing a shielding ring covering at least a portion of the threaded hole, the shielding ring can shield a portion of the locking member located within the threaded hole, thereby reducing the risk of the locking member dislodging from the threaded hole and affecting workpiece machining.

[0010] In some embodiments, the outer circumferential surface of the collar is provided with an annular groove, and at least a portion of the shielding ring is engaged within the annular groove. This annular groove allows for more stable installation of the shielding ring, improving the structural stability of the shielding component.

[0011] In some embodiments, the shielding member includes a collar and a shielding portion; the collar is movably sleeved on the air pipe along a first direction; the shielding portion is connected to the collar, and the collar is provided with the shielding portion at at least one end along the first direction, the shielding portion being configured to shield at least one air hole. Thus, the position of the shielding portion can be adjusted by moving the collar, thereby enabling the shielding portion to shield air holes blowing towards the side of the corresponding type of workpiece along the first direction. The air blowing device can be applied to workpieces of various sizes, improving the compatibility of the air blowing device and reducing the processing cost of the workpiece.

[0012] In some embodiments, the shielding part has a tubular structure and is sleeved on the air pipe. This reduces the risk of the shielding part falling off the air pipe and affecting the workpiece processing, making the workpiece processing more stable. Furthermore, the tubular structure of the shielding part facilitates its installation and reduces the difficulty of installation.

[0013] In some embodiments, the shielding part is inserted into the collar. This allows the shielding part and the collar to be detachably connected, facilitating the replacement of the shielding part and the collar and reducing the cost of using the shielding component.

[0014] In some embodiments, one end of the collar along the first direction is provided with an annular protrusion, which is inserted into the shielding portion. This makes the assembly of the shielding portion and the annular protrusion more convenient, the structure simple, and the connection method simple and convenient.

[0015] In some embodiments, the annular protrusion and the blocking portion are interference-fitted. This makes the installation of the blocking portion and the collar easier and reduces the installation cost of the blocking portion and the collar.

[0016] In some embodiments, the shielding part is made of polyethylene, polyvinyl chloride, polypropylene, polytetrafluoroethylene, rubber, or aluminum.

[0017] In some embodiments, there are multiple shielding members, which are configured to cooperate in blocking a portion of the air holes. By providing multiple shielding members, air holes at different locations can be blocked to reduce the impact of air holes on workpiece processing. The positions of the multiple shielding members can be adjusted to make the air blowing device applicable to more workpieces of different sizes, thereby improving the compatibility of the air blowing device and reducing the processing cost of the workpiece.

[0018] In some embodiments, the blocking member includes a blocking portion sleeved on the air tube, the blocking portion being configured to block at least one air hole; multiple blocking members include a first blocking member and a second blocking member arranged adjacent to each other along a first direction, the blocking portion of the first blocking member being insertable into the blocking portion of the second blocking member. Thus, the first blocking member and the second blocking member can cooperate to adjust their covering length along the first direction to cover air holes of corresponding length on the air tube, thereby achieving coverage of different numbers of air holes, making the air blowing device more widely applicable and more compatible.

[0019] Secondly, embodiments of this application provide a winding device, including a winding apparatus and an air blowing device provided in any of the embodiments of the first aspect. The winding apparatus is used to wind a workpiece; the air pipe is used to blow air onto the workpiece. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0032] In this application, the reference to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0033] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0034] In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0035] In this application, "multiple" means two or more (including two).

[0036] The machining of workpieces generally requires a certain degree of flatness. Before machining, the shape of some workpieces is prone to deformation due to their own stress or external forces, which affects the machining quality.

[0037] Taking an electrode assembly with a battery cell as an example, the electrode assembly includes a positive electrode, a negative electrode, and a separator. During the charging and discharging process of the battery cell, active ions (such as lithium ions) repeatedly insert and extract between the positive and negative electrodes. The separator is placed between the positive and negative electrodes to reduce the risk of short circuits between the positive and negative electrodes, while allowing active ions to pass through.

[0038] During the manufacturing process of electrode assemblies, the positive electrode, negative electrode, and separator can be wound into a coiled structure along the extension direction of the electrode assembly. During winding, the positive electrode is prone to detaching from the separator due to its own stress, causing wrinkles to form on the electrode assembly. This can lead to contact between the positive and negative electrodes, resulting in a short circuit and affecting the reliability of the electrode assembly. At the beginning of the winding process, air can be blown onto the positive electrode using an air blowing device to ensure it adheres smoothly to the separator, improving the flatness of the positive electrode and reducing the risk of wrinkles.

[0039] The blowing device may include an air tube, through which airflow is blown outward through air holes. When the blowing device blows air onto the positive electrode plate, the extension direction of the air tube and the width direction of the positive electrode plate are both parallel to a first direction, so that air is blown in the extension direction of the positive electrode plate. However, the airflow blowing onto both sides of the positive electrode plate along the first direction can easily cause the positive electrode plate to bend or wrinkle inward along the first direction. The impact of the airflow located on both sides of the positive electrode plate along the first direction can be reduced by fixing tape to the air tube, thereby blocking the airflow towards the air holes on both sides of the positive electrode plate.

[0040] However, when processing various types of electrode assemblies, which have multiple positive electrode plates of different widths, the air pipes are difficult to remove after the air holes are blocked by tape. The tape also easily contaminates the workpiece during processing. As a result, the air pipes are not compatible with the processing of positive electrode plates of various sizes. Therefore, when processing positive electrode plates of different sizes, different air blowing devices need to be changed, which increases the processing cost of the workpiece.

[0041] In view of this, in order to improve the compatibility of the air blowing device, this application provides an air blowing device, which includes an air tube and a blocking member. The air tube extends along a first direction and is provided with a plurality of air holes, which are spaced apart along the first direction. The blocking member is adjustablely disposed on the air tube along the first direction and is configured to block a portion of the air holes.

[0042] In such an air blowing device, the position of the blocking component can be adjusted along the first direction according to the size of the workpiece along the first direction, so that the blocking component can block the air holes that blow the airflow toward the side of the workpiece. This makes the air blowing device applicable to workpieces of various sizes, improves the compatibility of the air blowing device, and reduces the processing cost of the workpiece.

[0043] The following description, in conjunction with the accompanying drawings, explains the air blowing device and the winding equipment using the air blowing device.

[0044] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of a winding device 100 provided in some embodiments of this application. Embodiments of this application provide a winding device 100, which includes a winding device 20 and an air blowing device 10. The winding device 20 is used to wind a workpiece, and the air blowing device 10 is used to blow air onto the workpiece.

[0045] The air blowing device 10 blows air onto the workpiece to level the workpiece to be wound by the winding device 20.

[0046] Taking the workpiece as an electrode assembly as an example, the winding device 20 is used to wind the positive electrode sheet, negative electrode sheet, and separator of the electrode assembly to form a winding structure. The negative electrode sheet and separator are pre-stacked to form a pre-assembled electrode. The winding device 20 includes a first conveyor roller 201 for conveying the pre-assembled electrode, a second conveyor roller 202 for conveying the positive electrode sheet, and a winding section 203 for winding the electrode assembly. The first conveyor roller 201 conveys the pre-assembled electrode to the winding section 203. The air blowing device 10 can blow the positive electrode sheet onto the pre-assembled electrode conveyed to the winding section 203, so that the positive electrode sheet is flat against the separator, thereby reducing the risk of wrinkling of the positive electrode sheet. It can be understood that the air blowing device 10 can blow on the entire workpiece or only a part of the workpiece. In actual working conditions, air can be blown on the corresponding position of the workpiece according to actual needs.

[0047] Please refer to Figure 2 , Figure 2 This is a schematic diagram of the structure of an air blowing device 10 provided in some embodiments of this application. An embodiment of this application provides an air blowing device 10, including an air pipe 1 and a blocking member 2. The air pipe 1 extends along a first direction X and is provided with a plurality of air holes 11, which are spaced apart along the first direction X. The blocking member 2 is adjustablely disposed on the air pipe 1 along the first direction X, and is configured to block a portion of the air holes 11.

[0048] The air pipe 1 has a channel for airflow. Multiple air holes 11 are formed on the wall of the air pipe 1, and each air hole 11 is connected to the channel to allow airflow from the channel to be blown out of the air pipe 1 through the air holes 11. The multiple air holes 11 can be spaced apart along a first direction X, so that multiple airflows distributed along the first direction X can be blown out from the multiple air holes 11. The distance between two adjacent air holes 11 can be equal or unequal. The airflow blown out through the air holes 11 is directed towards the workpiece. The air pipe 1 can be connected to an air source, receiving gas supplied by the air source and transmitting the airflow to the workpiece through the air holes 11 on the air pipe 1. The air source can be an air compressor, an air tank, etc.

[0049] When the blocking member 2 blocks the air hole 11, the blocking member 2 can change the width of the airflow from the air hole 11 along the first direction X, and adjust the position of the airflow. After the blocking member 2 blocks the air hole 11, the airflow from the blocked air hole 11 is prevented from blowing towards the workpiece, while the airflow from the unblocked air hole 11 can blow towards the workpiece.

[0050] The number of blocking members 2 can be one or more. In embodiments with multiple blocking members 2, multiple blocking members 2 can jointly block a portion of continuous air holes 11 to cover the airflow outlet of a continuous area on the air pipe 1; alternatively, multiple blocking members 2 can block multiple discontinuous air holes 11 to cover the airflow outlet of multiple discontinuous areas on the air pipe 1. The blocking member 2 can move relative to the air pipe 1 along the first direction X, switching the position of the blocking member 2 blocking the air pipe 1, so that the blocking member 2 can be adjusted in position on the air pipe 1 along the first direction X. The blocking member 2 can be fixed to the air pipe 1 by contacting the air pipe 1 and by the friction between the blocking member 2 and the air pipe 1, and the position between the blocking member 2 and the air pipe 1 can be adjusted by overcoming the friction between the blocking member 2 and the air pipe 1. Alternatively, the shielding component 2 can be connected to the air tube 1 via fasteners to fix the shielding component 2 and the air tube 1, and the position between the shielding component 2 and the air tube 1 can be adjusted by loosening the fasteners; wherein, the fasteners can be bolts.

[0051] The shielding member 2 blocks part of the air hole 11. The shielding member 2 can block a portion of the multiple air holes 11. The blocked air holes 11 can be completely blocked by the shielding member 2, or only a portion of them can be blocked by the shielding member 2.

[0052] In this embodiment, the air pipe 1 can blow air outward through a plurality of air holes 11 spaced apart along the first direction X. The shielding member 2 can block a portion of the air holes 11, thereby blocking the airflow from the air holes 11 that blow air toward the side of the workpiece along the first direction X, thus reducing the impact of the airflow from those air holes 11 on the workpiece. By making the position of the shielding member 2 adjustable along the first direction X, the position of the shielding member 2 can be adjusted according to the size of the workpiece along the first direction X, so that the shielding member 2 can block the air holes 11 that blow air toward the side of the workpiece. This makes the blowing device 10 applicable to workpieces of various sizes, improving the compatibility of the blowing device 10 and reducing the processing cost of the workpiece.

[0053] In some embodiments, please refer to Figure 3 , Figure 3 for Figure 2 A sectional view of section AA. The air blowing device 10 also includes a locking member 3, which is configured to unlockably lock the shield 2 to the air tube 1.

[0054] The number of locking components 3 can be one or more. In embodiments with multiple locking components 3, only one locking component 3 may lock the shielding component 2 to the air pipe 1, or multiple locking components 3 may jointly lock the shielding component 2 to the air pipe 1. The locking component 3 may be a locking pin, bolt, etc.

[0055] By setting the locking component 3, on the one hand, the locking component 3 can reduce the risk of the shielding component 2 falling off and affecting the workpiece processing; on the other hand, the locking component 3 can lock the shielding component 2 to the air pipe 1, thereby fixing the position of the shielding component 2, making the shielding component 2 more stable in blocking the air hole 11, and improving the processing stability of the workpiece.

[0056] In some embodiments, please refer to Figure 4 , Figure 4 This is a schematic diagram of the structure of the shielding member 2 provided in some embodiments of this application. The shielding member 2 includes a collar 21 and a shielding portion 22. The collar 21 is movably sleeved on the air tube 1 along a first direction X. The shielding portion 22 is connected to the collar 21, and the shielding portion 22 is provided at least one end of the collar 21 along the first direction X. The shielding portion 22 is configured to shield at least one air hole 11. The locking member 3 is configured to unlockably lock the collar 21 to the air tube 1.

[0057] The shielding member 2 may consist of only one collar 21 and one shielding part 22, with one collar 21 connected to one shielding part 22; or the shielding member 2 may consist of one collar 21 and multiple shielding parts 22, with multiple shielding parts 22 connected to the same collar 21; or the shielding member 2 may consist of multiple collars 21 and multiple shielding parts 22, with multiple collars 21 and multiple shielding parts 22 corresponding one-to-one, or one collar 21 corresponding to multiple shielding parts 22.

[0058] The collar 21 is movably fitted onto the trachea 1 along the first direction X, so as to drive the blocking part 22 to move along the first direction X. The blocking part 22 may be provided at one end of the collar 21 along the first direction X, or the blocking part 22 may be provided at both ends of the collar 21 along the first direction X.

[0059] It can be that a shielding part 22 only shields one vent 11; or it can be that a shielding part 22 shields multiple vents 11.

[0060] The number of locking parts 3 can be one or more. One locking part 3 can lock one collar 21, or multiple locking parts 3 can lock the same collar 21.

[0061] In this embodiment, the shielding part 22 can move with the collar 21, and the locking member 3 can lock the collar 21 to the air pipe 1 to fix the position of the shielding part 22, so that the position of the shielding member 2 is more stable and the risk of the shielding member 2 shifting during the workpiece processing is reduced.

[0062] In some embodiments, please continue to refer to Figure 3 and Figure 4The collar 21 has an inner circumferential surface 211 surrounding the air tube 1, and the collar 21 is provided with a threaded hole 212. One end of the threaded hole 212 extends to the inner circumferential surface 211, and the locking member 3 is screwed into the threaded hole 212.

[0063] The locking member 3 is screwed into the threaded hole 212 so that the locking member 3 can extend out of the inner circumferential surface 211 of the collar 21 and abut against the pipe wall of the air pipe 1, thereby locking the collar 21 and the air pipe 1.

[0064] There can be multiple threaded holes 212, which are arranged at intervals along the circumference of the collar 21. Each threaded hole 212 corresponds to a locking element 3. The locking element 3 can be a countersunk bolt.

[0065] It is understood that the collar 21 has an outer peripheral surface, which may be a threaded hole 212 extending to the outer peripheral surface of the collar 21 so that the threaded hole 212 communicates with the outside to facilitate the installation of the locking member 3; or the threaded hole 212 may be connected to the outside of the collar 21 through a countersunk hole to facilitate the installation of the locking member 3.

[0066] In this embodiment, the locking member 3 can pass through the inner circumferential surface 211 and abut against the wall of the air tube 1, thereby fixing the collar 21 and the air tube 1, and fixing the air tube 1 and the shielding member 2.

[0067] In some embodiments, please refer to Figure 5 , Figure 5 This is an exploded view of the shielding member 2 and the collar 21 provided in some embodiments of this application. The shielding member 2 also includes a shielding ring 23, which is sleeved on the collar 21 and covers at least a portion of the threaded hole 212.

[0068] Along the extension direction of the threaded hole 212, the retaining ring 23 is located on the extension path of the threaded hole 212. The retaining ring 23 may cover only a portion of the threaded hole 212, or it may cover the entire threaded hole 212. The retaining ring 23 covers at least a portion of the threaded hole 212 so that the retaining ring 23 can restrict the position of the locking member 3 and reduce the risk of the locking member 3 disengaging from the collar 21.

[0069] The shielding ring 23 is fitted onto the collar 21, so that the shielding ring 23 can be fitted onto the trachea 1, reducing the risk of the shielding ring 23 falling off.

[0070] In this embodiment, by providing a shielding ring 23 to cover at least a portion of the threaded hole 212, the shielding ring 23 can shield a portion of the locking member 3 located in the threaded hole 212, thereby reducing the risk that the locking member 3 will disengage from the threaded hole 212 and affect the workpiece processing.

[0071] In some embodiments, please continue to refer to Figure 5The outer circumferential surface of the collar 21 is provided with an annular groove 213, and at least a portion of the blocking ring 23 is engaged in the annular groove 213.

[0072] The annular groove 213 is provided around the outer circumferential surface of the collar 21. The annular groove 213 can be connected to the threaded hole 212 so that when at least a part of the blocking ring 23 is engaged in the annular groove 213, it can restrict the locking member 3 in the threaded hole 212. Alternatively, the annular groove 213 and the threaded hole 212 can be provided at intervals, and the part of the blocking ring 23 located outside the annular groove 213 can restrict the locking member 3 in the threaded hole 212 from disengaging from the collar 21.

[0073] It is possible that only a portion of the blocking ring 23 is engaged in the annular groove 213; or it is possible that the entire blocking ring 23 is engaged in the annular groove 213.

[0074] In this embodiment, the annular groove 213 makes the installation of the shielding ring 23 more stable and improves the structural stability of the shielding member 2.

[0075] In some embodiments, please continue to refer to Figure 5 The outer circumferential surface of the collar 21 is also provided with a groove 215, which communicates with the annular groove 213 and passes through one end of the collar 21 along the first direction X.

[0076] There may be one or more grooves 215. In embodiments where there are multiple grooves 215, the multiple grooves 215 are spaced apart along the circumference of the collar 21.

[0077] By setting the groove 215 to communicate with the annular groove 213, and the groove 215 passing through one end of the collar 21 along the first direction X, it helps the shielding ring 23 to be installed into the annular groove 213 through the groove 215 or removed from the annular groove 213 through the groove 215, making the installation and removal of the shielding ring 23 more convenient.

[0078] In some embodiments, the shielding member 2 includes a collar 21 and a shielding portion 22. The collar 21 is movably sleeved on the air tube 1 along a first direction X. The shielding portion 22 is connected to the collar 21, and the collar 21 is provided with the shielding portion 22 at at least one end along the first direction X. The shielding portion 22 is configured to shield at least one air hole 11.

[0079] The shielding part 22 is provided on the trachea 1 via a collar 21. The collar 21 may be in contact with the trachea 1, and the relative positions of the collar 21 and the trachea 1 may be limited by friction. For example, the side of the collar 21 near the trachea 1 may be made of flexible rubber, which has an inner circumferential surface 211 for abutting against the trachea 1. The flexible rubber contacts the trachea 1 to limit the movement of the collar 21 relative to the trachea 1.

[0080] In this embodiment, the position of the blocking part 22 can be adjusted by moving the collar 21, so that the blocking part 22 can block the air hole 11 blowing towards the side of the corresponding workpiece along the first direction X. The blowing device 10 can be applied to a variety of workpieces of different sizes, which improves the compatibility of the blowing device 10 and reduces the processing cost of the workpiece.

[0081] In some embodiments, please continue to refer to Figure 2 and Figure 4 The shielding part 22 has a tubular structure and is fitted onto the trachea 1.

[0082] The shielding part 22 is sleeved on the trachea 1 to shield the air hole 11 on the trachea 1. The shielding part 22 can be attached to the outer periphery of the trachea 1, or the shielding part 22 can be spaced apart from the outer periphery of the trachea 1.

[0083] In this embodiment, by fitting the shielding part 22 onto the tubular air pipe 1, on the one hand, the risk of the shielding part 22 falling off the air pipe 1 and affecting the workpiece processing can be reduced, making the workpiece processing more stable; on the other hand, the tubular structure of the shielding part 22 is conducive to the installation of the shielding part 22 and reduces the installation difficulty of the shielding part 22.

[0084] In some embodiments, please refer to Figure 6 , Figure 6 for Figure 4 BB sectional view. The shielding part 22 is inserted into the collar 21.

[0085] The shielding part 22 can be inserted into the collar 21 to achieve the insertion and engagement of the shielding part 22 and the collar 21; or the collar 21 can be inserted into the shielding part 22 to achieve the insertion and engagement of the shielding part 22 and the collar 21.

[0086] In this embodiment, the shielding part 22 and the collar 21 are detachably connected, which facilitates the replacement of the shielding part 22 and the collar 21 and reduces the cost of using the shielding part 2.

[0087] In some embodiments, the shielding portion 22 engages with the collar 21.

[0088] In some embodiments, the shielding portion 22 and the collar 21 are connected by fasteners, which may be bolts.

[0089] In some embodiments, a ring 21 is provided with an annular protrusion 214 at one end along the first direction X, and the annular protrusion 214 is inserted into the shielding portion 22.

[0090] The annular protrusion 214 can be inserted into the shielding part 22 to fix the shielding part 22 and the annular protrusion 214; or the annular protrusion 214 can be inserted into the shielding part 22 and then connected to the shielding part 22 by fasteners to fix the shielding part 22 and the annular protrusion 214, wherein the fasteners can be bolts.

[0091] For example, the collar 21 has an annular protrusion 214 on the side facing the shielding part 22. The annular protrusion 214 is inserted into the shielding part 22 so that the outer peripheral surface of the annular protrusion 214 is interference-fitted with the inner peripheral surface 211 of the shielding part 22, thereby realizing the insertion and engagement of the shielding part 22 and the collar 21.

[0092] In this embodiment, the assembly of the shielding part 22 and the annular protrusion 214 is more convenient, the structure is simple, and the connection method is simple and convenient.

[0093] In some embodiments, the annular protrusion 214 and the shielding portion 22 are interference-fitted.

[0094] In this embodiment, the installation of the shielding part 22 and the collar 21 is more convenient, and the installation cost of the shielding part 22 and the collar 21 is reduced.

[0095] In some embodiments, the shielding part 22 is made of polyethylene, polyvinyl chloride, polypropylene, polytetrafluoroethylene, rubber, or aluminum.

[0096] In some embodiments, please refer to Figure 7 , Figure 7 This is a schematic diagram of the structure of the air blowing device 10 provided in some embodiments of this application. There are multiple blocking members 2, and the multiple blocking members 2 are configured to cooperate in blocking a portion of the air holes 11.

[0097] Multiple shielding elements 2 can be spaced apart, with multiple shielding elements 2 blocking air holes 11 that are not adjacent to each other on the air pipe 1; or multiple shielding elements 2 can be adjacent, with multiple shielding elements 2 blocking air holes 11 that are adjacent to each other in one area.

[0098] In this embodiment, by setting multiple shielding members 2, the multiple shielding members 2 can shield the air holes 11 at different positions to reduce the impact of the air holes 11 on the workpiece processing. The positions of the multiple shielding members 2 can be adjusted so that the air blowing device 10 can be applied to more workpieces of different sizes, thereby improving the compatibility of the air blowing device 10 and reducing the processing cost of the workpiece.

[0099] In some embodiments, please continue to refer to Figure 7The shielding member 2 includes a shielding portion 22, which is sleeved on the air tube 1 and configured to shield at least one air hole 11. A plurality of shielding members 2 include a first shielding member 25 and a second shielding member 26 arranged adjacent to each other along a first direction X, wherein the shielding portion 22 of the first shielding member 25 can be inserted into the shielding portion 22 of the second shielding member 26.

[0100] The shielding part 22 of the shielding member 2 can be one or more. One shielding part 22 can shield only one vent 11 or shield multiple vents 11.

[0101] The first shielding member 25 and the second shielding member 26 can jointly shield the same air hole 11, or they can cooperate to shield multiple air holes 11 continuously arranged in the same area on the air pipe 1. The shielding part 22 of the first shielding member 25 is inserted into the shielding part 22 of the second shielding member 26. The shielding part 22 of the first shielding member 25 and the shielding part 22 of the second shielding member 26 can move relative to each other in the first direction X to adjust the air hole 11 covered by the shielding part 22 of the first shielding member 25 and the air hole 11 covered by the shielding part 22 of the second shielding member 26.

[0102] For example, the blocking portion 22 of the first blocking member 25 can cover five consecutive air holes 11 arranged on the trachea 1, and the blocking portion 22 of the second blocking member 26 can also cover five consecutive air holes 11 arranged on the trachea 1. The air holes 11 blocked by the blocking portion 22 of the first blocking member 25 can be the five air holes 11 blocked by the second blocking member 26. In this way, the first blocking member 25 and the second blocking member 26 cooperate to cover five air holes 11. The blocking portion 22 of the first blocking member 25 covers five air holes 11, and the blocking portion 22 of the second blocking member 26 covers five air holes 11 adjacent to the five air holes 11 covered by the first blocking member 25. In this way, the first blocking member 25 and the second blocking member 26 cooperate to cover ten consecutively arranged air holes 11. It is understandable that the number of vents 11 blocked by the shielding part 22 is related to the length of the shielding part 22 along the first direction X, the spacing distance of the vents 11 along the first direction X, and the diameter of the vents 11. The specific number of vents 11 blocked by the shielding part 22 depends on the actual situation.

[0103] In this embodiment, the first blocking member 25 and the second blocking member 26 can cooperate to adjust their covering length along the first direction X to cover the corresponding length of the air holes 11 on the air tube 1, thereby achieving the covering of different numbers of air holes 11, making the air blowing device 10 more widely applicable and more compatible.

[0104] This application provides a winding device 100, including a winding device 20 and an air blowing device 10 as described in any of the above embodiments. The winding device 20 is used to wind a workpiece. The air pipe 1 is used to blow air onto the workpiece.

[0105] In some embodiments, the winding device 100 further includes an air guide plate 30, which is disposed on the air pipe 1 and is used to guide the airflow blown out of the air pipe 1 to the workpiece.

[0106] Please continue to refer to Figure 7 This application provides an air blowing device 10, including an air pipe 1 and a plurality of blocking members 2. The air pipe 1 extends along a first direction X and is provided with a plurality of air holes 11, which are spaced apart along the first direction X. The plurality of blocking members 2 are adjustablely disposed on the air pipe 1 along the first direction X, and are configured to block a portion of the air holes 11. The blocking member 2 includes a blocking portion 22, which is sleeved on the air pipe 1 and is configured to block at least one air hole 11. The plurality of blocking members 2 include a first blocking member 25 and a second blocking member 26 disposed adjacent to each other along the first direction X, and the blocking portion 22 of the first blocking member 25 can be inserted into the blocking portion 22 of the second blocking member 26. The air blowing device 10 also includes a locking member 3, which is configured to unlockably lock the blocking member 2 to the air pipe 1. The blocking member 2 includes a collar 21 and a blocking portion 22. A collar 21 is movably fitted onto the air tube 1 along a first direction X. A blocking portion 22 is connected to the collar 21, and the collar 21 is provided with a blocking portion 22 at at least one end along the first direction X. The blocking portion 22 is configured to block at least one air hole 11. The locking member 3 is configured to unlockably lock the collar 21 onto the air tube 1.

[0107] In this embodiment, the air pipe 1 can blow air outward through a plurality of air holes 11 spaced apart along the first direction X. The shielding member 2 can block a portion of the air holes 11, thereby reducing the impact of the airflow blowing from the air holes 11 on the workpiece along the first direction X. By making the position of the shielding member 2 adjustable along the first direction X, the position of the shielding member 2 can be adjusted according to the size of the workpiece along the first direction X, so that the shielding member 2 can block the air holes 11 that blow air towards the side of the workpiece. This makes the blowing device 10 applicable to workpieces of various sizes, improving the compatibility of the blowing device 10 and reducing the processing cost of the workpiece. By setting the locking member 3, on the one hand, the locking member 3 can reduce the risk of the shielding member 2 falling and affecting the processing of the workpiece; on the other hand, the locking member 3 can lock the shielding member 2 to the air pipe 1, thereby fixing the position of the shielding member 2, making the shielding member 2 more stable in blocking the air holes 11, and improving the processing stability of the workpiece. The blocking part 22 can move with the collar 21, and the locking member 3 can lock the collar 21 to the air pipe 1 to fix the position of the blocking part 22, making the position of the blocking member 2 more stable and reducing the risk of the blocking member 2 shifting during workpiece processing. The first blocking member 25 and the second blocking member 26 can cooperate to adjust their covering length along the first direction X to cover the corresponding length of the air holes 11 on the air pipe 1, thereby achieving the covering of different numbers of air holes 11, making the air blowing device 10 more widely applicable and more compatible.
