Description

Technical Field

[0001] The invention relates to the technical field of production and manufacturing, and in particular to a material tray locking device and a material coiling device. Background Art

[0002] In modern manufacturing, coils are widely used, especially in applications where continuous feeding is required, such as printing, textile, packaging and other industries. Coils are usually supplied in the form of trays and need to be mounted on a feed shaft for use. Traditional installation methods usually rely on threaded locking devices, which have some significant disadvantages.

[0003] Frequent replacement of material trays is a common operation during the production process. The traditional thread locking method requires the operator to use tools to loosen and tighten the operation, which is not only time-consuming and labor-intensive, but also reduces production efficiency. This method is obviously not ideal for modern manufacturing industries that require quick response and efficient production. In addition, the thread locking device also has directional problems in actual use. If the locking direction is consistent with the rotation direction of the discharge shaft, the thread may gradually loosen due to inertia, resulting in the inability to firmly fix the material tray on the discharge shaft. This not only affects the continuity of production, but may also cause equipment damage or production accidents. On the contrary, if the locking direction is opposite to the rotation direction, the thread may become tighter and tighter, and even cause the material tray to deform, thereby affecting product quality and production safety.

[0004] Therefore, there is an urgent need in the prior art for a tray locking device that can quickly and conveniently lock and unlock the tray, so as to improve production efficiency, reduce operating difficulty, and ensure the safety and stability of the production process.

[0005] BACKGROUND OF THE INVENTION The above information disclosed is only for understanding the background of the inventive concept and may contain information that does not constitute the prior art. Summary of the invention

[0006] Based on this, it is necessary to provide a material tray locking device and a material coiling equipment to address the above problems.

[0007] A material tray locking device is used to lock a material tray sleeved on the outer peripheral surface of a shaft body on the shaft body, and the material tray locking device comprises:

[0008] A shaft sleeve, the shaft sleeve is used to be sleeved on the outer peripheral surface of the shaft body, the shaft sleeve has a first end and a second end that are far away from each other in the axial direction, and the first end is used to abut against the material tray;

[0009] An extrusion portion, one end of which is connected to the inner peripheral surface of the sleeve, and the other end of which is a suspended end, which faces the second end and is surrounded by the inner peripheral surface of the sleeve to form an expansion groove;

[0010] A locking cylinder, which is used to be sleeved on the outer peripheral surface of the shaft body, and can extend into the shaft sleeve from the second end, and can move relative to the shaft sleeve to a locking position and an unlocking position under the action of an external force;

[0011] When in the locking position, the locking cylinder is at least partially squeezed into the expansion groove and fixed to the shaft sleeve, and the suspended end can be pressed close to and pressed against the outer peripheral surface of the shaft body under the pressure of the locking cylinder to achieve relative fixation of the shaft sleeve, the shaft body and the material tray;

[0012] When in the unlocking position, the locking cylinder withdraws from the expansion groove, and the sleeve can be separated from the locking cylinder, the shaft body, and the tray.

[0013] The above-mentioned tray locking device can at least achieve the following beneficial effects: the tray locking device of the present application adopts a combined structure of a sleeve, an extrusion part and a locking cylinder, making the overall structure more compact. The locking cylinder can extend from the second end of the sleeve under the action of external force, and squeeze into the expansion groove when in the locking position. At this time, the extrusion of the locking cylinder on the expansion groove makes the suspended end of the sleeve close to the outer peripheral surface of the shaft body inward, and through the increase of friction, a firm locking effect is achieved, avoiding the risk of the tray loosening or falling off. It should be emphasized that this design of the tray locking device of the present application simplifies the operation steps when locking. Only by inserting the locking cylinder into the expansion groove, the suspended end can be close to the outer peripheral surface of the shaft body to achieve the locking function, which is very convenient and efficient in operation. This friction locking mechanism effectively solves the problems caused by loose locking in traditional devices. The locking cylinder can also easily withdraw from the expansion groove under the action of external force to move to the unlocking position, release the extrusion of the sleeve, so that the sleeve, locking cylinder, shaft body and tray can be quickly separated. This feature greatly simplifies the disassembly and replacement process of the device, and solves the maintenance difficulties caused by the complex structure of the traditional device. It is understandable that during the production process, operators often need to replace the tray. The faster the tray is replaced, the shorter the production line is interrupted. Therefore, convenient disassembly and assembly become a key factor in improving production efficiency and reducing operational complexity. Therefore, the tray locking device of this application realizes the rapid disassembly and assembly of the tray through a sophisticated design, successfully solving the problems of inconvenient operation, unstable locking, and difficult maintenance of the traditional solution during the disassembly and assembly of the tray, and improving the working efficiency, ease of use and production efficiency of the equipment.

[0014] In some of the embodiments, an expansion protrusion is formed at one end of the locking cylinder facing the expansion groove, and when in the locking position, the expansion protrusion is at least partially squeezed into the expansion groove. In the locking position, through the squeezing effect of the expansion protrusion, the suspended end of the sleeve can fit more closely on the outer peripheral surface of the shaft body, ensuring that the material tray remains stable during high-frequency use and reducing the risk of loosening or falling off. In addition, this structural design simplifies the locking operation, and a firm lock can be achieved by simply pushing the expansion protrusion of the locking cylinder into place, which is convenient and efficient to operate. Conversely, when unlocking, it is only necessary to pull the expansion protrusion of the locking cylinder out of the expansion groove, further improving the efficiency and safety of the production process. Through this innovative design, the device not only improves the reliability of locking, but also optimizes the operating process, and solves the problems of unstable locking and complex operation existing in traditional devices.

[0015] In some embodiments, the expansion protrusion extends in an annular shape along the circumference of the locking cylinder. In this design, the expansion protrusion extends in an annular shape along the circumference of the locking cylinder, which can provide a more uniform and stable locking effect when locking. The annular expansion protrusion ensures that when in the locked position, it can be squeezed into the expansion groove evenly in the entire circumference, thereby achieving more reliable locking. This structure not only enhances the stability of the device, but also reduces local stress concentration and reduces the risk of loosening due to local wear or deformation. In addition, the annular design makes the locking and unlocking operations smoother, improves the durability and service life of the device, and also simplifies the assembly and maintenance process. Through this design, the device can maintain excellent performance in high-frequency use environments, further improving production efficiency and safety.

[0016] In some embodiments, the extrusion portion extends in an annular shape along the circumference of the sleeve, and the expansion groove is an annular groove. The annular extrusion portion and the annular expansion groove ensure that the force can be evenly distributed over the entire circumference when locking. This reduces local stress concentration, reduces wear and potential material fatigue. Since the contact surface of the expansion protrusion and the expansion recess is a continuous annular shape, the device can better resist external vibration and impact during use, thereby improving overall durability and reliability. Through this annular design, the sleeve is not only improved in locking effect, but also shows higher efficiency and reliability during production and maintenance. This design is widely used in mechanical systems that require high-strength and high-stability connections.

[0017] In some of the embodiments, the expansion protrusion gradually shrinks in the direction approaching the expansion groove, and the expansion groove is matched with the expansion protrusion. In this embodiment, the expansion protrusion is designed to gradually shrink in the direction of the expansion groove. This tapered shape allows the expansion protrusion to enter the expansion groove more easily during the locking process, and provides a secure locking effect after fully entering. The expansion groove is matched with the expansion protrusion, which means that the shape and size of the groove match the shape and size of the protrusion, thereby ensuring that the expansion protrusion can fit tightly against the inner wall of the expansion groove in the locked state. The gradually shrinking expansion protrusion design makes the assembly process smoother and reduces assembly difficulties caused by misalignment. The matched expansion groove and expansion protrusion ensure uniform pressure distribution during locking, increasing the stability and reliability of locking.

[0018] In some embodiments, the extrusion portion is integrally formed with the sleeve.

[0019] In some embodiments, the tray locking device further comprises a blocking member, which is fixed to the second end of the sleeve and at least partially exceeds the inner peripheral surface of the sleeve. A limiting convex rib is convexly provided on the outer peripheral surface of the locking cylinder. When in the locking position, the blocking member is located on the side of the limiting rib away from the sleeve, and the blocking member can abut against the limiting rib to limit the relative sliding of the sleeve and the locking cylinder. The blocking member at least partially exceeds the inner peripheral surface of the sleeve, which means that the blocking member will protrude from the inner space of the sleeve when installed. In the locking operation, the blocking member is located on the side of the limiting rib away from the sleeve. If the sleeve and the locking cylinder are relatively displaced, the blocking member can abut against the limiting rib, thereby limiting the relative sliding between the sleeve and the locking cylinder. Through the interaction between the blocking member and the limiting rib, a stable locking effect is maintained during use. This structure is suitable for applications requiring high reliability and safety because it can effectively prevent loosening or failure due to vibration or external force.

[0020] In some embodiments, the blocking member extends in an annular shape along the circumference of the sleeve. The annular blocking member can be evenly distributed over the entire circumference of the sleeve, which makes the force distribution more uniform during the locking process, reduces local stress concentration, and improves the stability and durability of the overall structure. Since the blocking member extends in an annular shape, it can provide a consistent limiting effect in all directions to prevent relative sliding in any direction. This design is particularly suitable for applications that need to withstand multi-directional forces.

[0021] In some of the embodiments, the limiting rib extends in an annular shape along the circumference of the locking cylinder. The annular limiting rib can provide a consistent limiting effect over the entire circumference of the locking cylinder. This ensures that in the locked state, when the locking cylinder and the sleeve tend to move away from each other, the blocking member can contact the limiting rib, thereby effectively preventing relative sliding between the sleeve and the locking cylinder. Since the limiting rib is annular, the force can be evenly distributed over the circumference of the locking cylinder when it is subjected to force, thereby reducing local stress concentration and the risk of material fatigue and damage. The annular limiting rib provides a continuous contact surface, which, combined with the annular blocking member, can further enhance the stability and safety of the entire locking device.

[0022] In some embodiments, the blocking member is integrally formed with the sleeve. The design of the blocking member and the sleeve being integrally formed provides multiple advantages. First, it improves the structural integrity, eliminates seams and connection points between components, thereby enhancing the overall strength and reliability, and reducing potential problems caused by loosening or failure of the connection parts. Secondly, this design simplifies the manufacturing process, reducing the complexity and cost of production by reducing the number of assembly steps and the required number of parts. In addition, the integral molding ensures precise alignment and fit between the blocking member and the sleeve, which is particularly important for applications that require high-precision positioning and locking. Since there are no independent connectors, this design can also reduce wear caused by relative movement during use, thereby extending the service life of the device. Finally, the integral molding allows for more efficient use of materials in the design, and the thickness and shape can be adjusted in different parts as needed to optimize performance and reduce weight. By integrally forming the blocking member with the sleeve, this embodiment improves the overall performance and reliability of the device and is suitable for applications that require high strength and high durability.

[0023] In some embodiments, the blocking member is detachably connected to the sleeve. The blocking member and the sleeve are detachably connected, which provides some advantages in flexibility and practicality. First, the detachable connection allows for more convenient maintenance and replacement. If a component is worn or damaged, the component can be replaced alone without replacing the entire assembly, thereby saving time and cost. Secondly, this design provides greater flexibility, so that different types of blocking members or sleeves can be adjusted or replaced as needed in different applications to meet specific functional requirements. In addition, the detachable design also helps to simplify transportation and storage, because the components can be packaged and handled separately, reducing volume and weight. Finally, this connection method can alleviate the problem of assembly tolerance to a certain extent, and achieve better adaptation and alignment by adjusting the connection method. Therefore, the design of detachable connection not only improves the adaptability and maintenance convenience of the system, but also enhances the overall practicality and economy.

[0024] In some embodiments, the blocking member is fixedly connected to the shaft sleeve. The blocking member and the shaft sleeve can be fixedly connected by bonding, welding, etc.

[0025] In some embodiments, the tray locking device further comprises a plurality of fasteners, the blocking member is annular and is formed by enclosing a plurality of blocking sub-rings, and the plurality of blocking sub-rings are fixed to the second end of the sleeve by a plurality of fasteners. By using a plurality of fasteners (such as rivets), the connection between the blocking sub-rings can be ensured to be firm, and the strength and stability of the overall structure can be enhanced. As fasteners, rivets have good vibration and impact resistance, and can maintain the firmness of the connection under dynamic load conditions. Secondly, the annular blocking member is composed of a plurality of sub-rings, which provides higher flexibility and adjustability. During the assembly process, the position or number of the sub-rings can be adjusted according to actual needs to adapt to sleeves or other components of different specifications. This modular design facilitates production and maintenance, and improves the adaptability of the device. In addition, if rivets are used as fasteners, the assembly process can be simplified. Rivet connection does not require thread processing, and the installation process is relatively simple and quick, which is suitable for mass production and reduces production costs.

[0026] In some embodiments, one end of the locking cylinder away from the sleeve is located outside the sleeve, and an operating ridge is formed on the outer peripheral surface of the end of the locking cylinder away from the sleeve, and the operating ridge is used for grasping to drive the locking cylinder to move relative to the sleeve to the locking position or the unlocking position. The provision of the operating ridge enables the user to grasp and operate the locking cylinder more easily, thereby simplifying the locking and unlocking operation process and improving the convenience of operation. Clear operating positions and grasping points not only reduce the possibility of misoperation, but also enhance the safety of the device, allowing users to maintain a high level of comfort and efficiency even in the case of frequent operation.

[0027] The present application also provides a material coiling device, which includes a shaft body, a material tray detachably mounted on the outer circumference of the shaft body, and a material tray locking device as described in any of the above embodiments.

[0028] Since the above-mentioned coiling equipment includes the tray locking device described in any of the above-mentioned embodiments, the coiling equipment also includes at least the following beneficial effects: the tray locking device of the present application adopts a combined structure of a sleeve, an extrusion portion and a locking cylinder, so that the overall structure is more compact. The locking cylinder can extend from the second end of the sleeve under the action of an external force, and squeeze into the expansion groove when in the locking position. At this time, the extrusion effect of the locking cylinder on the expansion groove causes the suspended end of the sleeve to be inwardly close to the outer peripheral surface of the shaft body. Through the increase in friction, a firm locking effect is achieved, avoiding the risk of the tray loosening or falling off. It should be emphasized that this design of the tray locking device of the present application simplifies the operating steps when locking. It only needs to insert the locking cylinder into the expansion groove to make the suspended end close to the outer peripheral surface of the shaft body to achieve the locking function, which is very convenient and efficient in operation. This friction locking mechanism effectively solves the problems caused by loose locking in traditional devices. The locking cylinder can also be easily withdrawn from the expansion groove under the action of external force to move to the unlocking position, release the squeeze on the sleeve, and enable the sleeve, locking cylinder, shaft body and tray to be quickly separated. This feature greatly simplifies the disassembly and replacement process of the device, and solves the maintenance difficulty caused by the complex structure in the traditional device. It can be understood that in the production process, the operator often needs to replace the tray. The faster the tray is replaced, the shorter the time the production line is interrupted. Therefore, convenient disassembly and assembly become the key factors to improve production efficiency and reduce operation complexity. Therefore, the tray locking device of the present application realizes the rapid disassembly and assembly of the tray through a sophisticated design, successfully solves the problems of inconvenient operation, unstable locking and difficult maintenance of the traditional solution during the disassembly and assembly of the tray, and improves the working efficiency, convenience of use and production efficiency of the equipment. Therefore, the coiling equipment can realize the rapid installation and disassembly of the tray, improve the efficiency and convenience of operation, and is suitable for occasions where the tray needs to be replaced frequently. Secondly, the stability of the locking device ensures the stability of the tray during the operation of the equipment, and prevents equipment failure or safety hazards caused by loose trays. Thirdly, the design of the locking device enables the equipment to maintain good performance after long-term use, reducing maintenance and replacement costs. In addition, through the optimized structural design, the equipment can adapt to trays of different specifications, enhancing the versatility and applicability of the equipment. In summary, this coiling equipment has significant advantages in terms of ease of operation, safety, durability and scope of application. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0039] See also Figures 1 to 6In some embodiments, the present invention provides a material tray locking device 10 for locking a material tray 30 sleeved on the outer circumferential surface of a shaft body 20 on the shaft body 20, wherein the material tray locking device 10 includes a sleeve 100, an extrusion portion 200 and a locking cylinder 300. The sleeve 100 is used to be sleeved on the outer peripheral surface of the shaft body 20. The sleeve 100 has a first end 110 and a second end 120 that are far away from each other in the axial direction. The first end 110 is used to abut the material tray 30. One end of the extrusion portion 200 is connected to the inner peripheral surface of the sleeve 100. The other end of the extrusion portion 200 is a suspended end 210. The suspended end 210 faces the second end 120 and is surrounded with the inner peripheral surface of the sleeve 100 to form an expansion groove 220. The locking cylinder 300 is used to be sleeved on the outer peripheral surface of the shaft body 20. The locking cylinder 300 can extend into the sleeve 100 from the second end 120, and the locking cylinder 300 can move to a locking position and an unlocking position relative to the sleeve 100 under the action of an external force. Figure 5 As shown, in the locking position, the locking cylinder 300 is at least partially squeezed into the expansion groove 220 and fixed to the sleeve 100, and the suspended end 210 can be pressed close to and pressed against the outer peripheral surface of the shaft body 20 under the pressure of the locking cylinder 300, so as to achieve relative fixation of the sleeve 100, the shaft body 20 and the tray 30. Figure 4 As shown, in the unlocked position, the locking cylinder 300 withdraws from the expansion groove 220, and the sleeve 100 and the locking cylinder 300, the shaft body 20, and the tray 30 can all be separated.

[0040] The above-mentioned tray locking device 10 can at least achieve the following beneficial effects: the tray locking device 10 of the present application adopts a combination structure of a sleeve 100, an extrusion part 200 and a locking cylinder 300, making the overall structure more compact. The locking cylinder 300 can extend from the second end 120 of the sleeve 100 under the action of an external force, and squeeze into the expansion groove 220 when in the locking position. At this time, the extrusion of the locking cylinder 300 on the expansion groove 220 makes the suspended end 210 of the sleeve 100 close to the outer peripheral surface of the shaft body 20 inward, and through the increase of friction, a firm locking effect is achieved, avoiding the risk of the tray 30 loosening or falling off. It should be emphasized that this design of the tray locking device 10 of the present application simplifies the operating steps when locking. It only needs to insert the locking cylinder 300 into the expansion groove 220 to make the suspended end 210 close to the outer peripheral surface of the shaft body 20 to achieve the locking function, which is very convenient and efficient in operation. This friction locking mechanism effectively solves the problems caused by loose locking in traditional devices. The locking cylinder 300 can also easily withdraw from the expansion groove 220 under the action of external force to move to the unlocking position, release the squeeze on the sleeve 100, so that the sleeve 100, the locking cylinder 300, the shaft body 20 and the tray 30 can be quickly separated. This feature greatly simplifies the disassembly and replacement process of the device, and solves the maintenance difficulties caused by the complex structure in traditional devices. It is understandable that in the production process, operators often need to replace the tray 30. The faster the tray 30 is replaced, the shorter the time the production line is interrupted. Therefore, convenient disassembly and assembly become a key factor in improving production efficiency and reducing operation complexity. Therefore, the tray locking device 10 of the present application realizes the rapid disassembly and assembly of the tray 30 through a sophisticated design, successfully solving the problems of inconvenient operation, unstable locking and maintenance difficulties in the traditional solution when disassembling the tray 30, and improving the working efficiency, convenience of use and production efficiency of the equipment.

[0041] Specifically, Figure 5 and Figure 6As shown, in some embodiments, the locking cylinder 300 is formed with an expansion convex portion 310 at one end facing the expansion groove 220, and when in the locking position, the expansion convex portion 310 is at least partially squeezed into the expansion groove 220. In the locking position, through the squeezing effect of the expansion convex portion 310, the suspended end 210 of the sleeve 100 can be more closely fitted on the outer peripheral surface of the shaft body 20, ensuring that the material tray 30 remains stable during high-frequency use and reducing the risk of loosening or falling off. In addition, this structural design simplifies the locking operation, and only needs to push the expansion convex portion 310 of the locking cylinder 300 into place to achieve a firm lock, which is convenient and efficient to operate. Conversely, when unlocking, only the expansion convex portion 310 of the locking cylinder 300 needs to be pulled out of the expansion groove 220, which further improves the efficiency and safety of the production process. Through this innovative design, the device not only improves the reliability of locking, but also optimizes the operation process, and solves the problems of unstable locking and complex operation existing in traditional devices.

[0042] More specifically, if Figure 3 and Figure 4 As shown, in some of the embodiments, the expansion protrusion 310 extends in an annular shape along the circumference of the locking cylinder 300. In this design, the expansion protrusion 310 extends in an annular shape along the circumference of the locking cylinder 300, which can provide a more uniform and stable locking effect when locked. The annular expansion protrusion 310 ensures that when in the locked position, it can be evenly squeezed into the expansion groove 220 in the entire circumference, thereby achieving more reliable locking. This structure not only enhances the stability of the device, but also reduces local stress concentration and reduces the risk of loosening due to local wear or deformation. In addition, the annular design makes the locking and unlocking operations smoother, improves the durability and service life of the device, and also simplifies the assembly and maintenance process. Through this design, the device can maintain excellent performance in a high-frequency use environment, further improving production efficiency and safety.

[0043] More specifically, if Figure 4 As shown, in some embodiments, the extrusion portion 200 extends in an annular shape along the circumference of the sleeve 100, and the expansion groove 220 is an annular groove. The annular extrusion portion 200 and the annular expansion groove 220 ensure that the force can be evenly distributed over the entire circumference when locking. This reduces local stress concentration, reduces wear and potential material fatigue. Since the contact surface of the expansion protrusion 310 and the expansion recess is a continuous annular shape, the device can better resist external vibration and impact during use, thereby improving overall durability and reliability. Through this annular design, the sleeve 100 is not only improved in locking effect, but also shows higher efficiency and reliability during production and maintenance. This design is widely used in mechanical systems that require high-strength and high-stability connections.

[0044] More specifically, if Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the expansion protrusion 310 gradually shrinks in the direction close to the expansion groove 220, and the expansion groove 220 is matched with the expansion protrusion 310. In this embodiment, the expansion protrusion 310 is designed to gradually shrink in the direction of the expansion groove 220. This gradually shrinking shape allows the expansion protrusion 310 to enter the expansion groove 220 more easily during the locking process, and provides a firm locking effect after fully entering. The expansion groove 220 is matched with the expansion protrusion 310, which means that the shape and size of the groove match the shape and size of the protrusion, thereby ensuring that the expansion protrusion 310 can fit tightly against the inner wall of the expansion groove 220 in the locked state. The design of the gradually shrinking expansion protrusion 310 makes the assembly process smoother and reduces the assembly difficulties caused by misalignment. The matching expansion groove 220 and the expansion protrusion 310 ensure that uniform pressure distribution is provided during locking, increasing the stability and reliability of locking.

[0045] More specifically, in some of the embodiments, the extrusion portion 200 and the sleeve 100 are integrally formed.

[0046] See also Figures 2 to 6 In some embodiments, the tray locking device 10 further includes a blocking member 400, which is fixed to the second end 120 of the sleeve 100 and at least partially exceeds the inner peripheral surface of the sleeve 100. A limiting rib 320 is convexly provided on the outer peripheral surface of the locking cylinder 300. When in the locking position, the blocking member 400 is located on the side of the limiting rib 320 away from the sleeve 100, and the blocking member 400 can abut against the limiting rib 320 to limit the relative sliding of the sleeve 100 and the locking cylinder 300. The blocking member 400 at least partially exceeds the inner peripheral surface of the sleeve 100, which means that the blocking member 400 will protrude from the inner space of the sleeve 100 when installed. In the locking operation, the blocking member 400 is located on the side of the limiting rib 320 away from the sleeve 100. If the shaft sleeve 100 and the locking cylinder 300 are relatively displaced, the blocking member 400 can abut against the limiting rib 320, thereby limiting the relative sliding between the shaft sleeve 100 and the locking cylinder 300. Through the interaction between the blocking member 400 and the limiting rib 320, a stable locking effect is maintained during use. This structure is suitable for applications requiring high reliability and safety, because it can effectively prevent loosening or failure due to vibration or external force.

[0047] Specifically, Figure 2 and Figure 3As shown, in some embodiments, the blocking member 400 extends in an annular shape along the circumference of the sleeve 100. The annular blocking member 400 can be evenly distributed on the entire circumference of the sleeve 100, which makes the force distribution more uniform during the locking process, reduces local stress concentration, and improves the stability and durability of the overall structure. Since the blocking member 400 extends in an annular shape, it can provide a consistent limiting effect in all directions to prevent relative sliding in any direction. This design is particularly suitable for applications that need to withstand multi-directional forces.

[0048] More specifically, in some of the embodiments, the limiting rib 320 extends in an annular shape along the circumference of the locking cylinder 300. The annular limiting rib 320 can provide a consistent limiting effect throughout the circumference of the locking cylinder 300. This ensures that in the locked state, when the locking cylinder 300 and the sleeve 100 tend to move away from each other, the blocking member 400 can contact the limiting rib 320, thereby effectively preventing the relative sliding between the sleeve 100 and the locking cylinder 300. Since the limiting rib 320 is annular, the force can be evenly distributed around the circumference of the locking cylinder 300 when it is subjected to force, reducing local stress concentration and reducing the risk of material fatigue and damage. The annular limiting rib 320 provides a continuous contact surface, which, combined with the annular blocking member 400, can further enhance the stability and safety of the entire locking device.

[0049] For example, in some embodiments, the blocking member 400 is integrally formed with the sleeve 100. The design of the blocking member 400 being integrally formed with the sleeve 100 provides multiple advantages. First, it improves the structural integrity, eliminates the seams and connection points between the components, thereby enhancing the overall strength and reliability, and reducing the potential problems caused by loosening or failure of the connection parts. Secondly, this design simplifies the manufacturing process, reduces the complexity and cost of production by reducing the assembly steps and the number of parts required. In addition, the integral molding ensures the precise alignment and fit between the blocking member 400 and the sleeve 100, which is particularly important for applications requiring high-precision positioning and locking. Since there are no independent connectors, this design can also reduce the wear caused by relative movement during use, thereby extending the service life of the device. Finally, the integral molding allows for more efficient use of materials in the design, and the thickness and shape can be adjusted at different locations as needed to optimize performance and reduce weight. By integrally molding the blocking member 400 with the sleeve 100, this embodiment improves the overall performance and reliability of the device, and is suitable for applications requiring high strength and high durability.

[0050] For another example, in some of the embodiments, the blocking member 400 is detachably connected to the sleeve 100. The blocking member 400 and the sleeve 100 are detachably connected, which provides some advantages in flexibility and practicality. First, the detachable connection allows for more convenient maintenance and replacement. If a component is worn or damaged, the component can be replaced alone without replacing the entire assembly, thereby saving time and cost. Secondly, this design provides greater flexibility, so that different types of blocking members 400 or sleeves 100 can be adjusted or replaced as needed in different applications to meet specific functional requirements. In addition, the detachable design also helps to simplify transportation and storage, because the components can be packaged and handled separately, reducing volume and weight. Finally, this connection method can alleviate the problem of assembly tolerance to a certain extent, and achieve better adaptation and alignment by adjusting the connection method. Therefore, the design of detachable connection not only improves the adaptability and maintenance convenience of the system, but also enhances the overall practicality and economy.

[0051] For another example, in some embodiments, the blocking member 400 is fixedly connected to the shaft sleeve 100. The blocking member 400 and the shaft sleeve 100 may be fixedly connected by bonding, welding, or the like.

[0052] For example, Figure 2 As shown, in some embodiments, the tray locking device 10 further includes a plurality of fasteners 500, the blocking member 400 is annular and is formed by enclosing a plurality of blocking sub-rings 410, and the plurality of blocking sub-rings 410 are fixed to the second end 120 of the sleeve 100 by a plurality of fasteners 500. By using a plurality of fasteners 500 (such as rivets), the connection between the blocking sub-rings 410 can be ensured to be stable, and the strength and stability of the overall structure can be enhanced. Rivets, as fasteners 500, have good vibration and impact resistance, and can maintain the firmness of the connection under dynamic load conditions. Secondly, the annular blocking member 400 is composed of a plurality of sub-rings, which provides higher flexibility and adjustability. During the assembly process, the position or number of the sub-rings can be adjusted according to actual needs to adapt to sleeves 100 or other components of different specifications. This modular design facilitates production and maintenance and improves the adaptability of the device. In addition, if rivets are used as fasteners 500, the assembly process can be simplified. Rivet connection does not require thread processing, and the installation process is relatively simple and quick, which is suitable for mass production and reduces production costs.

[0053] See also Figure 3 and Figure 4In some embodiments, one end of the locking cylinder 300 away from the sleeve 100 is located outside the sleeve 100, and an operating flange 330 is formed on the outer peripheral surface of the end of the locking cylinder 300 away from the sleeve 100, and the operating flange 330 is used for being grasped to drive the locking cylinder 300 to move to the locking position or the unlocking position relative to the sleeve 100. The provision of the operating flange 330 enables the user to grasp and operate the locking cylinder 300 more easily, thereby simplifying the locking and unlocking operation process and improving the convenience of operation. Clear operating positions and grasping points not only reduce the possibility of misoperation, but also enhance the safety of the device, so that users can maintain a high degree of comfort and efficiency even in the case of frequent operation.

[0054] In addition, Figure 5 and Figure 6 As shown, the present application also provides a coiling device, which includes a shaft body 20, a material tray 30 detachably mounted on the outer circumference of the shaft body 20, and a material tray locking device 10 as described in any of the above embodiments.

[0055] Since the above-mentioned coiling device includes the material tray locking device 10 described in any of the above-mentioned embodiments, the above-mentioned coiling device also includes at least the following beneficial effects: the material tray locking device 10 of the present application adopts a combined structure of a sleeve 100, an extrusion portion 200 and a locking cylinder 300, so that the overall structure is more compact. The locking cylinder 300 can extend from the second end 120 of the sleeve 100 under the action of an external force, and squeeze into the expansion groove 220 when in the locking position. At this time, the extrusion effect of the locking cylinder 300 on the expansion groove 220 causes the suspended end 210 of the sleeve 100 to be inwardly close to the outer peripheral surface of the shaft body 20, and through the increase in friction, a firm locking effect is achieved, avoiding the risk of the material tray 30 loosening or falling off. It should be emphasized that the design of the tray locking device 10 of the present application simplifies the operating steps when locking. It only needs to insert the locking cylinder 300 into the expansion groove 220 to make the suspended end 210 close to the outer peripheral surface of the shaft body 20 to achieve the locking function, which is very convenient and efficient in operation. This friction locking mechanism effectively solves the problems caused by loose locking in traditional devices. The locking cylinder 300 can also easily withdraw from the expansion groove 220 under the action of external force to move to the unlocking position, release the squeezing of the sleeve 100, and enable the sleeve 100, the locking cylinder 300, the shaft body 20 and the tray 30 to be quickly separated. This feature greatly simplifies the disassembly and replacement process of the device and solves the maintenance difficulties caused by the complex structure in traditional devices. It is understandable that during the production process, operators often need to replace the tray 30. The faster the tray 30 is replaced, the shorter the time the production line is interrupted. Therefore, convenient disassembly and assembly become key factors to improve production efficiency and reduce operation complexity. Therefore, the tray locking device 10 of the present application realizes the rapid disassembly and assembly of the tray 30 through a sophisticated design, successfully solves the problems of inconvenient operation, unstable locking and difficult maintenance of the traditional solution when disassembling and assembling the tray 30, and improves the working efficiency, convenience of use and production efficiency of the equipment. Therefore, the coiling equipment can realize the rapid installation and disassembly of the tray 30, improve the efficiency and convenience of operation, and is suitable for occasions where the tray 30 needs to be frequently replaced. Secondly, the stability of the locking device ensures the stability of the tray 30 during the operation of the equipment, and prevents equipment failure or safety hazards caused by the loosening of the tray 30. Thirdly, the design of the locking device enables the equipment to maintain good performance after long-term use, reducing maintenance and replacement costs. In addition, through the optimized structural design, the equipment can adapt to trays 30 of different specifications, enhancing the versatility and applicability of the equipment. In summary, this coiling equipment has significant advantages in terms of ease of operation, safety, durability and scope of application.
