Description

Technical Field

[0001] The present application relates to the technical field of winding equipment, and in particular to a synchronous drive mechanism and a winding machine. Background Art

[0002] Winding machines are widely used in many industries. For example, winding machines are needed in the yarn winding process.

[0003] A general winding machine is provided with a winding roller, which needs to rotate to wind the yarn around its surface. When the yarn on the winding roller is fully wound, a yarn layer is formed.

[0004] If the winding machine needs to improve processing efficiency, it needs to set up multiple winding rollers, and multiple winding rollers need to be set up with multiple sets of driving elements. If the number of driving elements is too large, the cost of consumables and power consumption will be too high. At the same time, it is also difficult to meet the requirement of synchronous rotation of all winding rollers. Summary of the Invention

[0005] In order to improve the above problems, the present application provides a synchronous drive mechanism and a winding machine.

[0006] The present application provides a synchronous drive mechanism and a winding machine that adopts the following technical solutions:

[0007] 7. The swiftly and minutely adjusting device for a wood-planer working table as claimed in claim 1, wherein said linking rod and said adjusting base are pivotally connected to each other with a bolt, and said bolt has a round shank to contact with said linking rod. said linking rod is pivotally connected to said linking rod. said linking rod is pivotally connected to said linking rod. said linking rod is pivotally connected to said linking rod.

[0008] By adopting the above technical solution, when the driving end of the rotary driving member drives the first rotating member to rotate, the first rotating member drives the adjacent second rotating member to rotate through the linkage member, and the second rotating member can drive the adjacent second rotating member to rotate through the linkage member. When the second rotating member rotates, the linkage shaft is synchronously driven to rotate along the pivot member, and the linkage shaft is connected to the winding roller, thereby driving the winding roller to rotate. A single rotary driving member can be used to synchronously drive all winding rollers in a linkage manner, thereby reducing consumables and power consumption while providing synchronous winding processing.

[0009] Optionally, at least two second rotating members are provided on the linkage shaft.

[0010] By adopting the above technical solution, the second rotating member can take over the transmission provided by the previous second rotating member, and can also transmit the transmission to the next second rotating member through the linkage member. The more second rotating members are arranged on a single linkage shaft, the more linkage shafts can be driven synchronously.

[0011] Optionally, the first rotating member and the second rotating member are pulleys, and the linkage member is a flat belt.

[0012] By adopting the above technical solution, the flat belt will be mounted on the first rotating member and the second rotating member, which can achieve the function of synchronous drive. The pulley transmission has the advantages of easy maintenance and low cost, and is suitable for common synchronous rotation scenarios. The flat belt transmission has low noise and strong adaptability to the environment.

[0013] Optionally, the first rotating member and the second rotating member are gears, and the linkage member is a chain.

[0014] By adopting the above technical solution, gear transmission has the characteristics of accurate transmission ratio and compact structure, which is suitable for occasions of high-precision synchronous rotation. The use of chain transmission can provide more accurate and reliable force and is also suitable for large torque transmission.

[0015] Optionally, a tensioning member is further provided on the mounting frame, and the tensioning member is in contact with the linkage member.

[0016] By adopting the above technical solution, the tensioning member contacts the linkage member, and the tensioning member mainly acts to tighten the linkage member, so as to avoid the linkage member from slipping due to loose contact when connected.

[0017] Optionally, the tensioning member includes a connecting seat, a sliding portion, a protruding portion, a limiting portion and a rolling portion; a sliding groove and a plurality of threaded holes are provided on the connecting seat, and the sliding portion is slidingly connected to the sliding groove; the protruding portion is installed on the sliding portion and is provided with a through hole, and the limiting portion passes through the through hole and is screwed to any of the threaded holes; the rolling portion is installed on the sliding portion and is in contact with the linkage member.

[0018] By adopting the above technical solution, the linkage part is prone to loosening during the long-term transmission process. Therefore, the sliding part drives the rolling part to move along the sliding groove, and the rolling part applies tensioning force to the linkage part. When the tensioning force is sufficient, the corresponding protrusion is penetrated by the limiting part and screwed with the threaded hole, thereby fixing the sliding part and the rolling part to provide tensioning effect.

[0019] Optionally, the tensioning member further includes an elastic portion; the elastic portion is located in the sliding groove, with one end of the elastic portion connected to the sliding portion and the other end connected to the inner wall of the sliding groove.

[0020] By adopting the above technical solution, when the elastic part is placed, there is no need to use the limiting part for screw connection. The elastic force applied by the elastic part to the sliding part is used to make the rolling part apply tensioning force to the linkage part, and the required tension requirement is adapted through the elastic force of the elastic part.

[0021] A winding machine includes a synchronous driving mechanism.

[0022] By adopting the above technical solution, the winding rollers of the winding machine are driven by a synchronous driving mechanism, so that the function of synchronously winding the yarn by multiple winding rollers is achieved.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When the driving end of the rotary driving member drives the first rotating member to rotate, the first rotating member drives the adjacent second rotating member to rotate through the linkage member, and the second rotating member can drive the adjacent second rotating member to rotate through the linkage member. When the second rotating member rotates, the linkage shaft is synchronously driven to rotate along the pivot member, and the linkage shaft is connected to the winding roller, thereby driving the winding roller to rotate. A single rotary driving member can be used to synchronously drive all winding rollers in a linkage manner, thereby reducing consumables and power consumption while providing synchronous winding processing;

[0025] 2. The second rotating member can receive the transmission provided by the previous second rotating member and can also transmit the transmission to the next second rotating member through the linkage member. The more second rotating members are arranged on a single linkage shaft, the more linkage shafts can be driven synchronously.

[0026] 3. The tensioning piece is in contact with the linkage piece. The main function of the tensioning piece is to tighten the linkage piece to avoid the linkage piece from being too loose during connection, which may cause slipping and other unstable connections.

[0027] 4. The linkage parts are prone to loosening during the long-term transmission process. Therefore, the sliding part drives the rolling part to move along the sliding groove, and the rolling part applies tensioning force to the linkage parts. When the tensioning force is sufficient, the limiting part passes through the corresponding raised part and is screwed to the threaded hole to fix the sliding part and the rolling part to provide tensioning effect.

[0038] The following is combined with Figure 1 -Attached Figure 4 , further details of this application are given.

[0039] The embodiments of the present application disclose a synchronous drive mechanism and a winding machine.

[0040] A synchronous drive mechanism is installed on a winding machine 1. The winding roller on the winding machine 1 needs to rotate during the yarn winding process in order to wrap the yarn around its surface. However, since the yarn on the winding roller is fully wound to form a yarn layer, if the processing efficiency needs to be improved, multiple winding rollers need to be provided. Multiple winding rollers require multiple sets of drive elements, resulting in excessive consumables and power consumption. It is also difficult to meet the requirements of synchronous rotation of all winding rollers. To this end, the present application mainly adopts the following solution to achieve synchronous rotation of multiple winding rollers through a set of synchronous drive mechanisms, thereby improving the working efficiency of the winding machine 1, reducing the manufacturing cost and operating cost of the equipment, and ensuring the winding quality.

[0041] refer to Figure 1 and Figure 2 As shown, the synchronous drive mechanism includes a mounting frame 2, a rotary drive member 3, a pivot member 4, a first rotating member 5, a second rotating member 6, a linkage member 7 and a linkage shaft 8; the mounting frame 2 is installed on the winding machine 1, and the mounting frame 2 includes a column and a beam. The rotary drive member 3 is installed at the top or bottom end of the mounting frame 2 along the vertical direction of the mounting frame 2. In this embodiment, it is installed on the top beam, and the column is used to support the entire set of synchronous drive mechanisms and the winding roller, and the beam is installed on the top of the column.

[0042] The rotating drive member 3 may be an electric motor or other types of drive elements, such as a hydraulic motor. The electric motor may be a DC motor or an AC motor, and different models may be selected according to different working requirements.

[0043] The first rotating member 5 is connected to the driving end of the rotary driving member 3 , so that the driving end of the rotary driving member 3 can drive the first rotating member 5 to rotate.

[0044] There are several pivot members 4, and the pivot members 4 can adopt pivot bearings. The pivot bearings are installed in sequence at preset intervals along the vertical direction of the mounting frame 2. The preset distance of the interval is determined by the actual height of the mounting frame 2 and the actual number of pivot members 4, and is not limited here. The linkage shafts 8 are consistent in number with the pivot members 4, and correspond one-to-one with the pivot members 4, and are pivotally connected to the pivot members 4. In this embodiment, the number of pivot members 4 and linkage shafts 8 is four groups, and the four groups of linkage shafts 8 are respectively located in the four pivot members 4 and can rotate along the pivot members 4. The linkage shafts 8 pass through the pivot bearings and are connected to the winding roller of the winding machine 1, thereby driving the winding roller to rotate.

[0045] There are a plurality of second rotating members 6 , which are respectively arranged on the linkage shafts 8 . A plurality of second rotating members 6 can be arranged on a single linkage shaft 8 , which is determined by the number of linkage shafts 8 required for transmission.

[0046] A linkage member 7 is sleeved between the first rotating member 5 and the second rotating member 6 , and a linkage member 7 is sleeved between adjacent second rotating members 6 . The first rotating member 5 can drive the second rotating member 6 to rotate through the linkage member 7 , and the adjacent second rotating members 6 can also be driven to rotate through the linkage member 7 .

[0047] Specifically, when the driving end of the rotary drive member 3 drives the first rotating member 5 to rotate, the first rotating member 5 drives the adjacent second rotating member 6 to rotate through the linkage member 7, and the second rotating member 6 can drive the adjacent second rotating member 6 to rotate through the linkage member 7. When the second rotating member 6 rotates, the linkage shaft 8 is synchronously driven to rotate along the pivot member 4, and the linkage shaft 8 is connected to the winding roller, thereby driving the winding roller to rotate. A single rotary drive member 3 can be used to synchronously drive all winding rollers in a linkage manner, so as to reduce consumables and power consumption while providing synchronous winding processing.

[0048] Among them, a dust cover is also provided outside the rotary driving member 3, which has the function of isolating dust and silencing noise, reducing the impact of dust on the rotary driving member 3 and reducing the noise generated during the driving process.

[0049] Furthermore, there are at least two second rotating members 6 on the linkage shaft 8, so that the second rotating member 6 can take over the transmission provided by the previous second rotating member 6, and can also transmit the transmission to the next second rotating member 6 through the linkage member 7. The more second rotating members 6 are set on a single linkage shaft 8, the more linkage shafts 8 can be driven synchronously.

[0050] In some embodiments, reference Figure 1As shown, the first rotating member 5 and the second rotating member 6 use pulleys, and the linkage member 7 uses a flat belt. The pulley surface is rough, and the flat belt is made of rubber or plastic, which can provide stable friction. The flat belt will be mounted on the first rotating member 5 and the second rotating member 6 to achieve the function of synchronous drive, and the pulley transmission has the advantages of easy maintenance and low cost, which is suitable for common synchronous rotation scenarios. The flat belt transmission has low noise and strong adaptability to the environment. When setting the flat belt and the pulley, it is necessary to determine the width, thickness, friction coefficient and other parameters of the flat belt according to the actual required weight or lubrication degree of the driving winding roller to ensure that it will not slip or fall off during the transmission process.

[0051] In another embodiment, reference Figure 2 As shown, the first rotating member 5 and the second rotating member 6 are gears, and the linkage member 7 is a chain. Compared with the belt drive method, the gear transmission has the characteristics of accurate transmission ratio and compact structure, which is suitable for high-precision synchronous rotation occasions. The use of chain transmission can provide more accurate and reliable force, and is also suitable for large torque transmission.

[0052] When the second rotating member 6 is a gear, the tooth surface requires high surface hardness and good wear resistance to withstand high-load working conditions. The chain also needs to adapt to the various tooth spacings of the gear to ensure the stability of the connection. The figure takes gear transmission as an example.

[0053] In some embodiments, reference Figure 2 or Figure 3 As shown, a tensioning member 9 is also provided on the mounting frame 2, and the tensioning member 9 is in contact with the linkage member 7. The main function of the tensioning member 9 is to adjust the tension of the linkage member 7, such as a chain or a flat belt, to avoid the linkage member 7 from being too loose during connection, resulting in slipping and other unstable connections.

[0054] For further reference, Figure 3 As shown, the tensioning member 9 includes a connecting seat 91, a sliding portion 92, a protruding portion 93, a limiting portion 94 and a rolling portion 95; a sliding groove 911 and a plurality of threaded holes are provided on the connecting seat 91, and the sliding portion 92 is slidingly connected to the sliding groove 911. The sliding portion 92 can adopt a slider, and the slider passes through a plurality of threaded holes during the sliding process along the sliding groove 911.

[0055] The raised portion 93 is mounted on the sliding portion 92 and is provided with a through hole. The limiting portion 94 passes through the through hole and is screwed to any threaded hole. The raised portion 93 can adopt a raised block. The through hole of the raised block and the threaded hole are on the same parallel line, so that the limiting portion 94 can pass through the through hole and the threaded hole. The limiting portion 94 can adopt a bolt. The raised portion 93 can slide along the sliding groove 911 with the sliding portion 92, and the through hole will pass through different threaded holes. According to the required degree of tensioning, after determining the tensioning degree, the limiting portion 94 is passed through the through hole and screwed into the threaded hole, so that the raised portion 93 and the sliding portion 92 can be fixed on the connecting seat 91.

[0056] The rolling portion 95 is installed on the sliding portion 92 and contacts the linkage part 7. The rolling portion 95 can be a roller. When the roller contacts the linkage part 7, whether it is a chain or a flat belt, it can roll along its surface, reducing the friction between the linkage part 7 and the tensioning part 9, so that it does not affect the transmission effect of the linkage part 7 while also providing tensioning force and improving transmission efficiency.

[0057] Specifically, the linkage part 7 is prone to loosening during the long-term transmission process. Therefore, the sliding part 92 drives the rolling part 95 to move along the sliding groove 911, and the rolling part 95 applies a tensioning force to the linkage part 7. When the tensioning force is sufficient, the limiting part 94 passes through the corresponding protrusion 93 and is screwed to the threaded hole, thereby fixing the sliding part 92 and the rolling part 95 to provide a tensioning effect.

[0058] Further, refer to Figure 4 As shown, the tensioning member 9 also includes an elastic portion 96; the elastic portion 96 is located in the sliding groove 911, and one end is connected to the sliding portion 92, and the other end is connected to the inner wall of the sliding groove 911. The elastic portion 96 can be a spring, and the spring can apply elastic force to the sliding portion 92. When the elastic portion 96 is set, there is no need to use the limiting portion 94 for screw connection. The elastic force applied by the elastic portion 96 to the sliding portion 92 is used to make the rolling portion 95 apply tensioning force to the linkage member 7, and the required tensioning requirement is adapted by the elastic force of the elastic portion 96.

[0059] Further, refer to Figure 4 As shown, a threaded groove is provided on the side of the connecting seat 91, which is connected to the sliding groove 911. An adjusting portion 97 is provided in the threaded groove. The adjusting portion 97 can be a bolt, and a moving block is connected to the bolt. The moving block is located in the sliding groove 911. One end of the elastic portion 96 is connected to the moving block, and the other end is connected to the sliding block.

[0060] As the bolt continues to rotate in the threaded groove, the position of the moving block in the sliding groove 911 is adjusted. The elastic force generated by the elastic part 96 is adjusted by utilizing the distance between the moving block and the sliding block to apply different tensioning forces to the rolling part 95, thereby adapting the linkage part 7 to different tensioning requirements.

[0061] The present application also provides a winding machine 1, comprising the synchronous drive mechanism in the above embodiment, and utilizing the synchronous drive mechanism to drive the winding rollers of the winding machine 1 to achieve the function of synchronously winding the yarn by multiple winding rollers.

[0062] The examples of this specific embodiment are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
