Abstract
Description
Technical Field
[0001] The utility model relates to a coil transmission shaft and belongs to the technical field of winding equipment. Background Art
[0002] In the roll label coding and detection equipment, it is necessary to use the transmission axis to change the transmission routing path of the roll material to complete the coding, detection, printing and other processes of the label. For the routing path of the roll material transmission, it is necessary to reasonably design the layout of the transmission axis, such as straight type, curved type or combination type, to guide the roll material to be transmitted along the predetermined path.
[0003] In existing technology, transmission shafts are primarily divided into fixed and driven shafts. Changing the coil transport path requires redesigning the transmission shaft layout and repositioning the fixed and driven shafts, a cumbersome process that increases coil transport time. Furthermore, the required tension during coil transport varies depending on the material being transported. As the coil transport path lengthens, existing transmission shafts struggle to maintain tension on the coil, leading to slippage between the coil and the transmission shaft, impacting coil transport and reducing production efficiency and product quality. Utility Model Content
[0004] In order to solve the above problems, the utility model provides a coil transmission shaft, which can not only adapt to the different trajectory paths of the coil, without the need to redesign the layout of the transmission shaft, thus saving the transmission time of the coil; it can also adjust the tension on the transmission shaft so that it can adapt to different coils, and when the routing path is lengthened, the transmission shaft can maintain the tension on the coil, thereby solving the problem of insufficient tension causing the coil and the transmission shaft to slip.
[0005] The utility model is achieved through the following technical solutions:
[0006] A coil material transmission shaft comprises: a rotating shaft, abutting against the coil material and used for transmitting the coil material;
[0007] upright columns, located on both sides of the rotating shaft and parallel to the axis of the rotating shaft;
[0008] a damper, located at one end of the rotating shaft;
[0009] a coupling, located between the rotating shaft and the damper, connecting the rotating shaft and the damper;
[0010] The support shaft is located on the side of the rotating shaft away from the damper. The rotating shaft is sleeved on the outside of the support shaft. The rotating shaft is rotatably connected to the support shaft.
[0011] In one embodiment of the present invention, a bearing is provided between the rotating shaft and the supporting shaft, and the bearing is sleeved on the outer side of the supporting shaft.
[0012] In one embodiment of the present invention, a first clamp and a second clamp are provided on the side of the column away from the damper, the first clamp and the second clamp are connected to the column, and the first clamp and the second clamp cooperate and are sleeved on the outer periphery of the support shaft.
[0013] In one embodiment of the present invention, the first clamp and the second clamp are movably connected. The first clamp and the second clamp can be movably connected by a bolt connection. By controlling the distance the bolt is screwed in, the distance between the first clamp and the second clamp can be adjusted, thereby changing the position of the column and adapting to different coil paths. This eliminates the need to redesign the coil transmission shaft layout, simplifies operation, and saves production time.
[0014] In one embodiment of the present invention, the gap between the rotating shaft and the first and second clamps is smaller than the width of the bearing. This prevents the bearings near the first and second clamps from slipping along the axis of the support shaft during prolonged rotation, causing them to separate from the rotating shaft and lose support for the shaft. In this case, the rotating shaft relies solely on the bearings between the rotating shaft and the end caps for rotational support, which can be easily damaged, thereby reducing the service life of the web transfer shaft.
[0015] In one embodiment of the present invention, an end cover is provided at one end of the rotating shaft away from the supporting shaft, and the end cover is located between the rotating shaft and the coupling to connect the rotating shaft and the coupling.
[0016] In one embodiment of the present invention, a bracket is provided between the column and the damper, and the bracket connects the column and the damper.
[0017] In one embodiment of the present invention, a support seat is further included. A through hole is provided in the support seat, which is located on a side of the rotating shaft away from the damper and is sleeved on the outer circumference of the support shaft.
[0018] In one embodiment of the present invention, the number of the bearings is at least two, and they are distributed on both sides of the inner hole of the rotating shaft.
[0019] A winding device comprises the coil transmission shaft.
[0020] Beneficial effects
[0021] 1. The coil transfer shaft provided by the present invention is equipped with an adjustable damper that can be adjusted according to actual needs. By adjusting the damper, the tension on the coil transfer shaft can be adjusted, making the coil transfer shaft adaptable to a variety of coils. In addition, when the coil routing path is lengthened, adjusting the damper can maintain the tension between the coil transfer shaft and the coil, solving the problem of insufficient tension causing slippage between the coil and the transfer shaft, thereby improving coil transfer efficiency and ensuring product quality.
[0022] 2. The coil transfer shaft provided by this invention is equipped with a column that increases the wrap angle between the coil and the shaft, increasing the friction between the two, making the coil more stable during transfer and improving coil transfer efficiency. By adjusting the first and second clamps, the position of the column can be changed, thereby changing the coil transfer path. This adapts to coils with various transfer paths, eliminating the need to reposition the transfer shaft, making operation simple and saving production time. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] like Figs. 1-2 As shown, this embodiment provides a roll material transmission shaft, which is used to change the transmission routing path of the roll material and adjust the roll material tension on the transmission shaft in the roll label coding detection equipment, thereby realizing the coding, detection, printing and other processes of the label.
[0030] In some embodiments, the coil transmission shaft includes a support base 1, a support shaft 9, a rotating shaft 5, a coupling 6 and a damper 7. The support base 1 is located at one end of the coil transmission shaft and is provided with a through hole. The support base 1 can be connected to the frame to provide support for the coil transmission shaft. The support shaft 9 is a columnar structure, one end of which is connected to the support base 1, and the support base 1 is sleeved on the outside of the support shaft 9. The rotating shaft 5 is a cylinder with a through hole provided therein. The rotating shaft 5 is sleeved on the side of the support shaft 9 away from the support base 1. The rotating shaft 5 is rotatably connected to the support shaft 9 and can rotate around the support shaft 9. There are two bearings 8, which are located on both sides of the rotating shaft 5. The bearings 8 are sleeved on the outside of the support shaft 9, and the rotating shaft 5 is sleeved on the outside of the bearings 8. The rotating shaft 5 is rotatably connected to the support shaft 9 through the bearings 8. An end cover 11 is provided on the side of the rotating shaft 5 away from the support seat 1, and the end cover 11 abuts against the rotating shaft 5 to prevent the bearing 8 from sliding along the axial direction of the support shaft 9. A protruding round shaft is provided on the side of the end cover 11 away from the rotating shaft 5, and the round shaft is connected to the coupling 6.
[0031] In some embodiments, a damper 7 is provided on the side of the coil transmission shaft away from the support base 1. The damper 7 is an adjustable damper that can be adjusted according to actual needs so that it outputs the torque required by the coil transmission shaft. The coupling 6 is used to connect the circular shaft and the damper 7 on the end cover 11, and transmit the torque transmitted by the damper 7 to the rotating shaft 5 through the end cover 11, thereby driving the rotating shaft 5 to coil the material. By adjusting the damper 7, the tension on the transmission shaft can be adjusted so that the coil transmission shaft can adapt to various different coils. In addition, when the coil routing path is lengthened, by adjusting the damper 7, the coil transmission shaft can maintain the tension between the coil and the coil, solving the problem of insufficient tension causing slippage between the coil and the transmission shaft, thereby improving the transmission efficiency of the coil and ensuring the quality of the product.
[0032] In some embodiments, the coil transmission shaft further includes two columns 4, symmetrically distributed on either side of the rotating shaft 5. The columns 4 can increase the wrap angle of the coil on the rotating shaft 5, that is, the contact area between the coil and the rotating shaft 5, thereby increasing the friction between the coil and the rotating shaft 5. By increasing the friction between the two, the coil can be more stable during transmission and less likely to slip or fall off, thereby improving the efficiency of coil transmission. A bracket 10 is connected to the side of the column 4 near the damper 7. The bracket 10 is located between the coupling 6 and the damper 7. The bracket 10 is sleeved on the outside of the output shaft of the damper 7 and is fixedly connected to the damper 7. The bracket 10 provides support for the column 4 and the damper 7.
[0033] In some embodiments, a first clamp 2 and a second clamp 3 are connected to the side of the column 4 near the support base 1. The first and second clamps 2 and 3, together with the bracket 10, provide support for the column 4. The first and second clamps 2 and 3 cooperate with each other, fixed to the outside of the support shaft 9 and abutting the support base 1. The first and second clamps 2 and 3 can be flexibly connected via bolts. By controlling the distance the bolts are screwed in, the distance between the first and second clamps 2 and 3 can be adjusted, thereby changing the position of the column 4 to adapt to different coil paths. This eliminates the need to redesign the coil transmission shaft layout, simplifies operation, and saves production time.
[0034] Optionally, in some embodiments, the coiled material transmission shaft can be used as a driven shaft by removing the first clamp 2, second clamp 3, column 4, connecting plate 10, coupling 6, and damper 7. The coiled material transmission shaft can be used as a transmission shaft in lieu of the fixed shaft and driven shaft, or it can be used as a driven shaft by removing some components. The preferred method of use can be determined based on actual circumstances.
[0035] Optionally, the gap between the rotating shaft 5 and the first and second clamps 2 and 3 should be smaller than the width of the bearing 8 to prevent the bearing 8 near the first and second clamps 2 and 3 from slipping along the axis of the support shaft 9 during long-term rotation, causing the bearing 8 to separate from the rotating shaft 5 and resulting in the bearing 8 being unable to provide support for the rotating shaft 5. In this case, the rotating shaft 5 relies solely on the bearing 8 between the rotating shaft 5 and the end cover 11 for rotational support, which is easily damaged, thereby reducing the service life of the web conveyor shaft.
[0036] Optionally, the bracket 10 and the column 4 can be set to a sliding connection to facilitate the adjustment of the position of the column 4 in conjunction with the first clamp 2 and the second clamp 3, thereby adapting to coils with different paths.
[0037] The working principle of the present invention is as follows: the coil passes through the gap between the column 4 and the rotating shaft 5 and forms a covering around the rotating shaft 5. The damper 7 outputs a corresponding torque according to the different coils and the length of the coil routing path. The torque is transmitted to the end cover 11 through the coupling 6. The end cover 11 is connected to the rotating shaft 5, and the torque transmitted by the coupling 6 is transmitted to the rotating shaft 5, driving the rotating shaft 5 to rotate around the support shaft 9 to realize the transmission of the coil. The column 4 abuts against the coil, thereby increasing the wrap angle of the coil to the rotating shaft 5, increasing the friction between the coil and the rotating shaft 5, and making the coil more stable during transmission. By adjusting the first clamp 2 and the second clamp 3, the position of the column 4 can be adjusted so that the coil transmission shaft can adapt to different coil transmission paths.
[0038] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
