Description

Technical Field

[0001] This utility model relates to a winding machine and a combined winding device, belonging to the technical field of equipment for winding, coiling or placing filamentous materials. Background Technology

[0002] In the textile industry, yarn is usually transported in rolls, so the produced yarn needs to be wound onto spools using a winding machine. Similarly, some electrical wires are also sold in rolls and require winding onto spools using a winding machine.

[0003] Chinese utility model patent CN217172766U discloses a winding machine with automatic spool clamping. The machine includes a base with a fixed plate and a support plate fixed on it. A drive shaft is rotatably mounted on the support plate, one end of which is connected to the output shaft of a motor, and the other end is inserted into a shaft hole at the right end of the winding spool. A limiting plate is provided at the end of the drive shaft to stop the winding spool's end face. A cylinder is mounted on the fixed plate, and a pressure plate is connected to the piston rod end of the cylinder. A rotating plate is rotatably connected to the pressure plate. In use, the cylinder first moves the pressure plate and rotating plate to the left, then the right end of the winding spool is fitted onto the end of the drive shaft. Next, the cylinder controls the pressure plate and rotating plate to move to the right, causing the rotating plate to insert into a circular hole at the left end of the winding spool, thus clamping and fixing the winding spool together with the limiting plate. When disassembly is required after winding, the cylinder controls the pressure plate and rotating plate to move to the left to remove the winding spool and the coiled wire or electrical wire.

[0004] The aforementioned winding machine consists of a base, a fixed plate, and a support plate forming the frame. A cylinder, acting as the power source for the pressure plate and rotating plate, connects the pressure plate and the frame. Due to the cylinder's length, the distance between the rotating plate and the frame is relatively large. To ensure the winding drum can be inserted, the distance between the fixed plate and the support plate needs to be sufficiently large. This results in a large lateral dimension of the frame and a large lateral space occupied by the entire winding machine, making its placement inconvenient. Furthermore, the presence of two support plates, with the motor controlling the drive shaft rotation mounted on the outermost support plate, also contributes to the large lateral dimension of the winding machine. When workshop space is limited but multiple winding machines need to be arranged, this type of winding machine becomes difficult to implement. Utility Model Content

[0005] The purpose of this utility model is to provide a winding machine to solve the problem that the existing technology uses a cylinder connected between the pressure plate and the frame, resulting in a large lateral dimension of the frame and a large lateral space occupied by the entire winding machine, which is inconvenient to arrange. The purpose of this utility model is also to provide a combined winding device to solve the above problems.

[0006] To achieve the above objectives, the winding machine of this utility model adopts the following technical solution: A winding machine includes a frame and a clamping member for clamping one end of a bobbin and rotatable relative to the frame. The frame is equipped with a linear drive device for driving the clamping member to move linearly, a drive member for engaging with the other end of the bobbin, and a rotary drive device for controlling the rotation of the drive member, thereby rotating the bobbin. The linear drive device includes a rotating member rotatably mounted on the frame, a gear transmission mechanism, chain transmission mechanism, or belt transmission mechanism for driving the rotating member to rotate and containing a rotary power source, and a linear actuator threadedly engaged with the rotating member to perform linear motion. The frame is provided with a guide structure for guiding the linear actuator. The clamping member and the linear actuator are rotatably engaged. The rotary power source is located inside the frame and / or the output shaft of the rotary power source is arranged perpendicularly to the rotating member.

[0007] The beneficial effects of the above technical solution are as follows: This utility model is an improved invention, which further defines the linear drive device. The linear drive device includes a rotating component, a transmission mechanism containing a rotating power source, and a linear drive component. The frame is provided with a guide structure to guide the linear drive component. When the rotating power source is working, the rotating component can be driven to rotate through a gear transmission mechanism, a chain transmission mechanism, or a belt transmission mechanism. Under the action of the guide structure, the linear drive component can only move in a straight line. Since the clamping component and the linear drive component can be rotatably coupled, the linear drive component can drive the clamping component to move to clamp the end of the spool, thereby cooperating with the drive component to clamp the spool. Then, under the action of the rotary drive device, the spool can be driven to rotate. The clamping component can rotate relative to the linear drive component, so it will not affect the smooth rotation of the spool. In addition, the rotary power source is located inside the frame and / or the output shaft of the rotary power source is arranged perpendicular to the rotating part, that is, the output shaft of the rotary power source is not coaxial with the rotating part. The rotary power source itself does not occupy the space between the clamping part and the frame, and the clamping part can be arranged closer to the frame. Therefore, the lateral dimension of the frame can be reduced. At the same time, the rotary power source will not increase the lateral dimension of the winding machine. Therefore, the lateral space occupied by the winding machine can be reduced, which facilitates the arrangement of the winding machine.

[0008] Furthermore, the rotating component is a rotating wheel, and the direct-acting component passes through the rotating wheel and is threaded into the inner hole of the rotating wheel. The outer circumference of the rotating wheel is provided with a wheel groove for mounting a belt or with meshing teeth for meshing with a gear or chain.

[0009] Furthermore, the direct-acting member has an inner hole, and the clamping member includes an extension shaft that extends into the inner hole of the direct-acting member. A first bearing is installed between the extension shaft and the inner hole of the direct-acting member, and the clamping member is rotatably engaged with the direct-acting member through the first bearing.

[0010] Furthermore, the end of the direct-acting member is provided with an inwardly extending flange, the outer ring of the first bearing abuts against the flange, the extended shaft includes a smooth shaft section and a threaded section connected to the smooth shaft section, the inner ring of the first bearing is mounted on the smooth shaft section, and a nut is installed on the threaded section, the nut being used to directly or indirectly press the inner ring of the first bearing.

[0011] Furthermore, a washer is fitted onto the shaft, and the washer is sandwiched between the nut and the inner ring of the first bearing. The nut indirectly presses the inner ring of the first bearing through the washer.

[0012] Furthermore, the rotating wheel is mounted on the frame via a second bearing, and the rotating wheel and the frame are respectively provided with annular grooves that are interference-fitted with the inner and outer rings of the second bearing.

[0014] Furthermore, both the rotating wheel and the rotational power source are located inside the frame.

[0015] Furthermore, the rotary drive device includes a gear transmission structure, chain transmission structure, or belt transmission structure for controlling the rotation of the drive component and containing a motor, with the motor located inside the frame.

[0016] To achieve the above objectives, the combined winding device of this utility model adopts the following technical solution: A combined winding device includes at least two winding machines arranged side by side. Each winding machine includes a frame and a clamping member for clamping one end of a bobbin and rotatable relative to the frame. The frame is equipped with a linear drive device for driving the clamping member to move linearly, a drive member for driving the other end of the bobbin, and a rotary drive device for controlling the rotation of the drive member and thus driving the bobbin to rotate. The linear drive device includes a rotating member rotatably mounted on the frame, a gear transmission mechanism, chain transmission mechanism, or belt transmission mechanism for driving the rotating member to rotate and containing a rotary power source, and a linear actuator threaded to the rotating member to perform linear motion. The frame is provided with a guide structure for guiding the linear actuator. The clamping member and the linear actuator are rotatably engaged. The rotary power source is located inside the frame and / or the output shaft of the rotary power source is arranged perpendicular to the rotating member.

[0017] The beneficial effects of the above technical solution are as follows: This utility model is an improved invention, further defining the winding machine. The linear drive device of the winding machine includes a rotating component, a transmission mechanism containing a rotating power source, and a linear drive component. The frame is provided with a guide structure to guide the linear drive component.

Then, under the action of the rotary drive device, the bobbin can be driven to rotate. The clamping component can rotate relative to the linear drive component, so it will not affect the smooth rotation of the bobbin. In addition, the rotary power source is located inside the frame and / or the output shaft of the rotary power source is arranged perpendicular to the rotating part, that is, the output shaft of the rotary power source is not coaxial with the rotating part.

Therefore, the lateral dimension of the frame can be reduced. At the same time, the rotary power source will not increase the lateral dimension of the winding machine. Therefore, the lateral space occupied by the winding machine can be reduced, which facilitates the arrangement of the winding machine.

[0028] To address the technical problems existing in the prior art, the basic concept of this utility model is to adopt a linear drive device in the form of a lead screw and nut, and through the transition of a gear transmission mechanism, chain transmission mechanism, or belt transmission mechanism, the rotary power source is located inside the frame or / and the output shaft of the rotary power source is arranged perpendicular to the rotating part, which does not occupy the space between the clamping part and the frame, and does not increase the lateral dimension of the winding machine, thus facilitating the arrangement of the winding machine.

[0029] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0030] Example 1 of the combined winding device of this utility model: like Figure 1As shown, the combined winding equipment includes at least two winding machines 1 arranged side by side. In this embodiment, there are four winding machines 1 arranged adjacent to each other. The entire combined winding equipment does not occupy a large lateral space, achieving the goal of arranging multiple winding machines in a limited space to improve production efficiency. Specifically, the combined winding equipment also includes a base (not shown in the figure), on which each winding machine 1 is arranged.

[0031] like Figure 2 and Figure 3 As shown, the winding machine 1 includes a frame, which includes a fixed frame 2 and a rotatable tilting frame mounted on the fixed frame 2. The tilting frame includes two tilting plates 4 arranged parallel to each other. A fixed shaft 3 is fixedly connected between the two side plates of the fixed frame 2, and the fixed shaft 3 passes through the two tilting plates 4 of the tilting frame. The tilting frame can rotate around the fixed shaft 3. Two bobbins 14 are installed on the tilting frame. When one bobbin 14 is fully wound with yarn, the rotation of the tilting frame causes the other bobbin 14 to rotate to the winding position, which can realize uninterrupted winding of yarn. This principle is the same as the yarn winding device for an automatic winding machine disclosed in Chinese Utility Model Patent No. CN218024662U, and will not be described in detail here.

[0032] The two reels 14 are installed in the same way. Taking one of the reels 14 as an example, combined with... Figure 2 , Figure 3 and Figure 4 As shown, the winding machine 1 includes a clamping member 7 for clamping one end of the bobbin 14 and rotatable relative to the frame. The clamping member 7 includes a pressure plate 7-1 and an extension shaft 7-2 connected to the pressure plate 7-1. The pressure plate 7-1 is used to press the end of the bobbin 14 and has a protrusion that can be inserted into the inner hole of the bobbin 14.

[0033] A linear drive device for driving the pressing member 7 to move linearly is mounted on the frame. Specifically, the linear drive device includes a rotating member rotatably mounted on the left flip plate 4, a belt drive mechanism for driving the rotating member to rotate and containing a rotational power source, and a direct-acting member that is threadedly engaged with the rotating member to perform linear motion. In this embodiment, the rotating member is a rotating wheel 5, and the direct-acting member is a lead screw 6 that passes through the rotating wheel 5 and is threadedly engaged with the inner hole of the rotating wheel 5. The pressing member 7 is rotatably engaged with the lead screw 6, and the left flip plate 4 is provided with a guide structure to guide the lead screw 6, thereby forming a lead screw and nut mechanism.

[0034] Furthermore, the outer circumference of the rotating wheel 5 is provided with a groove for mounting the first belt 13. The aforementioned rotational power source is a first motor 20, which is fixed on the left-side flip plate 4. The output end of the first motor 20 is equipped with a first pulley 19. The first belt 13 is wound around the first pulley 19 and the rotating wheel 5. When the first motor 20 is working, it can drive the first pulley 19 to rotate, thereby driving the rotating wheel 5 to rotate under the action of the first belt 13. Consequently, the lead screw 6 performs linear work under the constraint of the guide structure. The lead screw 6 and the clamping member 7 can only rotate relative to each other in the circumferential direction and cannot move relative to each other in the axial direction. This allows the lead screw 6 to drive the clamping member 7 to move together, enabling the pressure plate 7-1 to move closer to or further away from the bobbin 14. After the pressure plate 7-1 clamps the bobbin 14, the clamping member 7 and the bobbin 14 can rotate together without affecting the normal winding operation of the bobbin 14.

[0035] like Figure 4 As shown, the lead screw 6 has an inner hole, and the extension shaft 7-2 of the clamping member 7 extends into the inner hole of the lead screw 6. A first bearing 8 is installed between the extension shaft 7-2 and the inner hole of the lead screw 6. The clamping member 7 is rotatably engaged with the lead screw 6 through the first bearing 8, which can reduce the friction when the clamping member 7 rotates.

[0036] Furthermore, the end of the lead screw 6 is provided with an inwardly extending retaining flange 6-1. The outer ring of the first bearing 8 abuts against the retaining flange 6-1. The extending shaft 7-2 includes a smooth shaft section and a threaded section connected to the smooth shaft section. The inner ring of the first bearing 8 is installed on the smooth shaft section, and a nut 10 is installed on the threaded section. The nut 10 is used to directly or indirectly press the inner ring of the first bearing 8, thus achieving the limiting installation of the first bearing 8. Of course, since the inner ring of the first bearing 8 is interference-fitted with the smooth shaft section of the extending shaft 7-2, it is necessary to control the installation position of the first bearing 8 on the smooth shaft section so that when the nut 10 is tightened, it can both pre-tighten the first bearing 8 and maintain a gap between the retaining flange 6-1 and the pressure plate 7-1 to facilitate the smooth rotation of the clamping member 7.

[0037] Specifically, a washer 9 is fitted onto the shaft 7-2. The washer 9 is sandwiched between the nut 10 and the inner ring of the first bearing 8. The nut 10 indirectly presses the inner ring of the first bearing 8 through the washer 9. This achieves both tightening of the inner ring of the bearing and preventing the nut 10 from loosening.

[0038] like Figure 4As shown, the left-side flip plate 4 is provided with a through hole 4-1 for the lead screw 6 to pass through. The diameter of the through hole 4-1 is larger than the outer diameter of the lead screw 6. The above-mentioned guiding structure is a guide block 11 provided on the wall of the through hole 4-1. The lead screw 6 is provided with a guide groove 6-2 for the guide block 11 to extend into. The guide block 11 is fixed or integrally provided in the through hole 4-1, without occupying the space outside the flip plate 4, so that the distance between the flip plate 4 and the fixed frame 2 can be minimized, thereby reducing the lateral dimension of the frame.

[0039] Meanwhile, the rotating wheel 5, the first belt 13, and the first motor 20 are all located inside the frame, that is, inside the left tilting plate 4, without occupying the space outside the tilting plate 4, ensuring that there is only a very small rotational gap between the tilting plate 4 and the fixed frame 2. The rotating wheel 5 is mounted on the frame via the second bearing 12. The rotating wheel 5 and the left tilting plate 4 are respectively provided with annular grooves that are interference-fitted with the inner and outer rings of the second bearing 12. This structure is simple and compact, which can minimize the lateral dimensions of the components. Of course, there is an appropriate gap between the rotating wheel 5 and the left tilting plate 4 to ensure that the rotating wheel 5 can rotate smoothly relative to the left tilting plate 4.

[0040] like Figures 2-4 As shown, a drive component 15 for transmission cooperation with the other end of the spool 14 is rotatably mounted on the right-side flip plate 4. A rotary drive device is also mounted on the right-side flip plate 4 to control the rotation of the drive component 15, thereby driving the spool 14 to rotate. Specifically, in this embodiment, the drive component 15 is a tensioning clamp, which includes a tensioning block. The principle is to use the centrifugal force during rotation to throw the tensioning block out, thereby driving the spool 14 to rotate. The tensioning clamp can be pneumatic or hydraulic, etc. The specific structure and working principle are prior art and will not be described further in this utility model.

[0041] The rotary drive device includes a belt drive structure for controlling the rotation of the drive member 15 and containing a second motor 16. The second motor 16 is fixed on the right-side tilting plate 4, and a second pulley 17 is installed at the output end of the second motor 16. The drive member 15 has a groove for winding a second belt 18 around the drive member 15 and the second pulley 17. When the second motor 16 is working, it can drive the second pulley 17 to rotate, which in turn drives the drive member 15 to rotate under the action of the second belt 18. The drive member 15 drives the bobbin 14 to rotate together, so that the yarn is wound around the outside of the bobbin 14.

[0042] Meanwhile, the drive unit 15, the second pulley 17, and the second motor 16 are all located inside the frame, that is, inside the right-side flip plate 4, without occupying the space outside the flip plate 4. This ensures that there is only a very small rotation gap between the flip plate 4 and the fixed frame 2, which can reduce the lateral dimension of the frame, making the lateral dimension of a single winding machine relatively small, which is convenient for layout. It also allows more winding machines to be arranged in the limited lateral space, thereby improving production efficiency without occupying a lot of space.

[0043] When using this modular winding device, to install a new spool 14, firstly, the pressing member 7 is moved closer to the left-side flipping plate 4 by the linear drive device, creating sufficient distance between the pressing member 7 and the drive member 15. Then, the right end of the spool 14 is fitted onto the outside of the drive member 15, and pneumatic tensioning is used to fix the drive member 15 and the spool 14 in place. Then, the pressing member 7 is moved toward the spool 14 by the linear drive device until it presses against the left end of the spool 14. During winding, the flipping frame first rotates 180 degrees, rotating the spool 14 to the winding position. Then, the drive member 15 is rotated by the rotary drive device, which in turn drives the spool 14 to rotate, thus winding the thread around the outside of the spool 14. When it is necessary to remove the wound thread and spool, the flipping frame first rotates 180 degrees, and then the pressing member 7 is moved away from the spool 14 by the linear drive device, allowing the wound thread and spool to be unwound.

[0044] In summary, this utility model uses the screw and nut principle to control the linear movement of the clamping component 7, and sets up a belt drive mechanism to control the rotation of the rotating wheel 5, so that the output shaft of the first motor 20 is arranged in parallel with the rotating wheel 5 and the screw 6. Moreover, the belt drive mechanism is located inside the frame, which does not occupy the external space of the frame, reduces the lateral dimension of the frame, reduces the lateral space occupied by the winding machine, and facilitates the arrangement of the winding machine.

[0045] In other embodiments of the combined winding device: the driving component can also be a clamp without a tensioning function, but rather a conical clamping component. The clamping component is inserted into the inner hole of the spool, and the conical surface of the clamping component presses against the opening of the spool. When the clamping component on the other side presses against the spool, the spool can be fixed. Of course, in other embodiments, the driving component may include an extension shaft that extends into the inner hole of the spool and a baffle fixed on the extension shaft. The baffle engages with the end face of the spool, and when the clamping component on the other side presses against the spool, the spool can also be fixed.

[0046] In other embodiments of the combined winding equipment: the rotation drive device can also control the rotation of the drive component by a gear transmission structure or a chain transmission structure, in which case the gear transmission structure or chain transmission structure can also be arranged inside the frame.

[0047] In other embodiments of the combined winding equipment: the winding machine can be equipped with only one spool. After the spool is full, it is removed and replaced with a new spool. That is, the winding machine does not include a flipping frame. In this case, the mechanism for driving the spool to rotate and pressing the spool is directly mounted on the fixed frame. The gear transmission structure, chain transmission structure, or belt transmission structure that controls the rotation of the drive component can also be set on the outside of the fixed frame. Of course, a motor can also be directly connected to the drive component, thus eliminating the intermediate transmission structure. The motor is arranged on the outside of the fixed frame. In these cases, since the linear drive device still uses the screw and nut principle, the overall lateral dimension of the winding machine can be reduced compared to the prior art. Especially when only two winding machines are arranged side by side, the rotary drive device of the left winding machine can be arranged on the outside of the left side of the frame, and the rotary drive device of the right winding machine can be arranged on the outside of the right side of the frame. The rotary drive devices on both sides do not affect other equipment, and the overall structure of the winding equipment is still compact.

[0048] In other embodiments of the combined winding device, the rotary power source in the linear drive can also be a hydraulic motor or a pneumatic motor.

[0049] In other embodiments of the combined winding equipment, the rotating wheel can also be driven by a gear transmission mechanism. In this case, the outer circumference of the rotating wheel is provided with meshing teeth for meshing with the gear. Of course, in other embodiments, the rotating wheel can also be driven by a chain transmission mechanism. In this case, the outer circumference of the rotating wheel is provided with meshing teeth for meshing with the chain. In these cases, the rotating wheel and the rotation power source can still be arranged inside the frame, that is, the gear or chain is arranged inside the frame.

[0050] In other embodiments of the combined winding equipment: the rotating wheel can also be arranged on the outside of the frame. In this case, the rotating wheel can be driven by a gear transmission mechanism, a chain transmission mechanism, or a belt transmission mechanism. The gear, chain, sprocket, belt, or pulley is arranged on the outside of the frame, while the rotational power source is still arranged on the inside of the frame.

[0051] In other embodiments of the combined winding equipment: when the rotating component is driven to rotate by a gear transmission mechanism, chain transmission mechanism or belt transmission mechanism, the rotating component may include a mounting shaft and a rotating wheel mounted on the mounting shaft to prevent rotation. The mounting shaft is responsible for rotating on the frame. In this case, the rotating wheel is a standard gear, sprocket or pulley.

[0052] In other embodiments of the combined winding equipment: when a gear transmission mechanism is used to drive the rotating part to rotate, the gear in the gear transmission mechanism can be a cylindrical gear or a bevel gear. When a cylindrical gear is used, the output shaft axis of the rotating power source is parallel to the axis of the rotating part. When a bevel gear is used, the output shaft axis of the rotating power source is perpendicular to the axis of the rotating part. At this time, the rotating power source can be set inside the frame or outside the frame. Since the rotating power source is generally a device with a certain length, the axial direction of the output shaft of the rotating power source is in the same direction as the length direction of the rotating power source. Therefore, setting it outside the frame and arranging the output shaft perpendicular to the rotating part can still reduce the lateral dimension of the winding machine compared to setting it outside the frame and parallel to the rotating part.

[0053] In other embodiments of the combined winding device: a guide member may be additionally fixed on the outer side of the frame, the guide member including a guide block extending into the guide groove of the linear actuator, that is, the guide block is not on the wall of the through hole.

[0054] In other embodiments of the combined winding device: the rotating wheel may include a mounting shaft, or the rotating component may include a mounting shaft and a rotating wheel mounted on the mounting shaft to prevent rotation, wherein the mounting shaft may pass through the frame and rotate in conjunction with a through hole on the frame via a bearing.

[0055] In other embodiments of the combined winding device: washers are no longer required on the extension shaft, and the nut directly presses against the inner ring of the first bearing.

[0056] In other embodiments of the combined winding device: the end of the linear actuator may no longer be provided with a retaining flange, and the extension shaft may no longer include a threaded section, that is, no nut is installed. In this case, the interference fit between the outer ring of the first bearing and the inner hole of the linear actuator, as well as the interference fit between the inner ring of the first bearing and the extension shaft, are used to maintain a certain relative positional relationship between the clamping member and the linear actuator. At the same time, the characteristic of the bearing to withstand a certain axial force (such as an angular contact ball bearing) is used to enable the linear actuator to drive the clamping member to move and transmit the axial force to the clamping member.

[0057] In other embodiments of the combined winding device: the rotational engagement between the linear actuator and the clamping member can also be achieved by providing an annular groove on the end face of the linear actuator, the clamping member including a connecting tube, the end of the connecting tube having an outwardly extending annular flange, the end of the connecting tube and the annular flange being placed in the annular groove and being able to rotate circumferentially relative to the annular groove, and simultaneously fixing a two-part baffle to the linear actuator with screws, the baffle covering part of the annular groove, restricting the annular flange within the annular groove, and preventing the clamping member from detaching from the linear actuator. In this case, the linear actuator can be hollow or solid.

[0058] In other embodiments of the combined winding equipment: the lead screw can be rotatably mounted on the frame via bearings. In this case, the lead screw acts as a rotating component. To facilitate driving the lead screw to rotate, a gear, pulley, or sprocket needs to be installed on the lead screw to prevent rotation. In this case, the linear actuator is equivalent to a large nut. The lead screw passes through the linear actuator and engages with the threaded inner hole of the linear actuator. The structure of the clamping component can be the same as in the previous embodiment, except that the connecting tube of the clamping component needs to be sleeved outside the lead screw and rotatably engage with the linear actuator through the aforementioned annular groove, annular flange, and two-half baffle. In this case, to guide the linear actuator, a guide rod can be fixed on the frame. The guide rod passes through the linear actuator to ensure the linear movement of the linear actuator.
