Abstract
Description
Technical Field
[0001] This application relates to the field of storage tank insulation technology, and in particular to a cylinder wrapping device. Background Technology
[0002] In the existing horizontal storage tank, the process of wrapping the outer surface with insulation paper generally involves workers pasting the insulation paper wrapping film onto the surface of the tank along a direction perpendicular to the tank's axis. The equipment is then rotated so that the insulation paper is completely wrapped around the tank. After this process, the insulation paper needs to be manually cut before wrapping the next piece. This process is repeated until the entire surface of the tank is completely covered.
[0003] The above methods of wrapping the outer surface of the cylinder result in more joints, take longer, and make it difficult to control the misalignment and overlap between adjacent rings of insulation paper. The tightness of wrapping multiple insulation papers cannot be controlled, making it impossible to ensure that the wrapping effect of each cylinder surface is consistent and making it difficult to control product quality.

[0047] This application provides a cylindrical wrapping device for wrapping a wrapping film 5 around the outer periphery of a horizontally placed cylindrical body 2.
[0048] Figure 1 A longitudinal view of the cylinder wrapping device is shown. Figure 2 A simplified top view of the cylinder wrapping device is shown.
[0049] Reference Figure 1 The cylindrical wrapping device of this application includes at least two roller frames 1, a traveling base 3, and an unwinding frame 4. At least two roller frames 1 are spaced apart longitudinally, and multiple roller frames 1 are used to support and rotate a horizontally placed cylindrical body 2 along the longitudinal direction. The cylindrical body 2 is placed along the longitudinal extension direction. The traveling base 3 is spaced apart on one side of the roller frames 1 and can reciprocate relative to the roller frames 1 along the longitudinal direction. The unwinding frame 4 is mounted on the traveling base 3 and is equipped with an unwinding roller 41 and a pressure roller 42. The unwinding roller 41 is used to place the wrapping film 5 and allows the wrapping film 5 to rotate for unwinding. Below the pressure roller 42, there is a conveying space 421 for the wrapping film 5 to pass through. The pressure roller 42 is located in a horizontal plane and is inclined relative to the longitudinal direction, so that the pressure roller 42 extends towards the roller frames 1 in a direction gradually closer to the traveling base 3 in the longitudinal direction of travel.
[0050] The wrapping film 5 is attached to the pressure roller 42 and passes through the conveying space 421 before extending to the outer periphery of the cylinder 2 on the roller frame 1. The roller frame 1 drives the cylinder 2 to rotate, causing the wrapping film 5 to wrap around the outer periphery of the cylinder 2. The traveling base frame 3 moves to complete the wrapping film 5 wrapping the cylinder 2 at different axial positions.
[0051] The cylinder 2 is placed on the roller frame 1 in a longitudinally extending manner. That is, multiple roller frames 1 jointly support a cylinder 2 that extends longitudinally.
[0052] This application utilizes the cooperation of the traveling frame 3 and the roller frame 1 to enable the wrapping film 5 to be continuously wound from the axial beginning to the end of the cylinder 2 in a spiral manner, reducing the number of wrapping joints of the wrapping film 5 on the surface of the cylinder 2 and improving the wrapping efficiency. Furthermore, the wrapping film 5 is unwound from the unwinding roller 41 and adheres to the lower surface of the pressure roller 42, and then output from the conveying space 421 to the surface of the cylinder 2. The pressure roller 42 maintains stable tension of the wrapping film 5, facilitating stable wrapping of the wrapping film 5 on different axial surfaces of the cylinder 2 and improving wrapping stability.
[0053] Reference Figure 2 In this application, the pressure roller 42 is horizontally positioned on the unwinding frame 4 and can move longitudinally with the traveling base frame 3. The axial extension direction of the pressure roller 42 is inclined relative to the longitudinal direction, meaning there is an angle between the axial extension direction of the pressure roller 42 and the axial extension direction of the cylinder 2. This causes the end of the pressure roller 42 that moves forward on the traveling base frame 3 to gradually approach the roller frame 1, resulting in different wrapping angles of the wrapping film 5 around the cylinder 2 in the longitudinal direction. The difference in the contact arc length between the two sides of the wrapping film 5 and the outer surface of the cylinder 2 creates an asymmetrical tension distribution, which compensates for the uneven stretching caused by the longitudinal movement of the pressure roller 42 on both sides of the wrapping film 5. This allows the wrapping film 5 to better conform to the surface of the cylinder 2 during winding, thereby reducing wrinkles on the outer surface of the cylinder 2. Simultaneously, it reduces the overlap between adjacent wrapping films 5, improving the utilization rate of the wrapping film 5. Furthermore, it meets product process requirements and better achieves the effect of heat insulation and preventing external heat transfer to the inner tank of the cylinder 2.
[0054] The roller frame 1 of this application is provided at least two at longitudinal intervals, capable of supporting the axial ends of the horizontally placed cylinder 2. The cylinder 2 of this application has a cylindrical structure. In fact, the cylinder 2 can be the central cylindrical position of a cryogenic storage tank, which is used to store cryogenic media, and the cryogenic storage tank can be sealed with end caps at both axial ends of the cylinder 2.
[0055] In some embodiments, the bottom of the traveling frame 3 is provided with wheels 32, and the roller frame 1 is provided with longitudinally extending tracks 33 at intervals on one side of the lateral side. The tracks 33 are laid on the bottom surface, and the traveling frame 3 can be longitudinally guided by moving along the tracks 33 via the wheels 32. The traveling frame 3 of this application is provided with a power unit, which is used to drive the traveling frame 3 to move longitudinally at a preset traveling speed, thereby improving the automation effect. The power unit includes a motor and transmission devices such as belts and pulleys, which can drive the wheels 32 to start and stop, and can precisely adjust and control the traveling speed of the wheels 32 according to parameters such as the width of the wrapping film 5, the preset overlap width of the wrapping, and the rotation speed of the cylinder 2, thereby improving the winding efficiency and accuracy of the wrapping film 5. In addition, the power unit can drive the traveling frame 3 to move back and forth longitudinally, thereby enabling the wrapping film 5 to wrap the cylinder 2 from different longitudinal positions.
[0056] In this application, the unwinding roller 41 and the pressure roller 42 are rotatably mounted on the unwinding frame 4. Both the unwinding roller 41 and the pressure roller 42 extend along a horizontal plane, and they can be parallel to each other. Alternatively, there can be an angle between the axial extension directions of the unwinding roller 41 and the pressure roller 42. During production, the pressure roller 42 is lower than the top of the cylinder 2, and the wrapping film 5 at the bottom of the pressure roller 42 winds upward from the top of the cylinder 2, maintaining tension on the wrapping film 5 by the pressure roller 42. Exemplarily, the roller frame 1 also includes a lifting mechanism to adjust the height of the cylinder 2 located on the roller frame 1. Alternatively, a lifting structure is provided between the traveling base frame 3 and the unwinding frame 4 to adjust the height of the pressure roller 42.
[0057] Figure 3 A schematic diagram of the structure of the traveling base frame 3 and the unwinding frame 4 is shown. Figure 4 The bottom view of the traveling frame 3 and the unwinding frame 4 is shown.
[0058] Combination Figures 1 to 4 A rotating component 431 is provided between the unwinding frame 4 and the traveling base frame 3. The rotating component 431 allows the unwinding frame 4 to rotate relative to the traveling base frame 3, thereby adjusting the angle α1 between the axial direction and the longitudinal direction of the pressure roller 42. The unwinding frame 4 can rotate horizontally relative to the traveling base frame 3 through the rotating component 431, thereby driving the pressure roller 42 to adjust the angle α1 between itself and the longitudinal direction. That is, in actual production, the angle between the axial extension direction of the pressure roller 42 and the axial extension direction of the cylinder 2 can be adjusted. The tilt angle of the pressure roller 42 with respect to the longitudinal direction can be adapted to different sizes of cylinder 2, different thicknesses or materials of wrapping film 5, and production factors such as the rotation speed of the cylinder 2 and the longitudinal movement speed of the traveling base frame 3, so that the wrapping film 5 can fit the cylinder 2 more closely, making it suitable for different application scenarios and improving applicability.
[0059] In this application, both the unwinding roller 41 and the pressure roller 42 are rotatably mounted on the unwinding frame 4 and can rotate with the unwinding frame 4 relative to the traveling base frame 3.
[0060] Furthermore, the included angle α1 between the axial and longitudinal directions of the pressure roller 42 is between ±35°.
[0061] The included angle α1 between the axial direction and the longitudinal direction of the pressure roller 42 is between -35° and 35°, and the overall adjustable angle range is within 70°. This allows the pressure roller 42 to adjust its angle by swinging back and forth relative to the longitudinal direction, so that the wrapping film 5 can be wrapped from any axial side of the cylinder 2 through the pressure roller 42, flexibly adapting to production needs.
[0062] Specifically, when the angle between the pressure roller 42 and the longitudinal direction is 0°, that is, when the pressure roller 42 extends longitudinally, and the cylinder 2 has a first end and a second end in the axial direction, when the traveling frame 3 moves from the position corresponding to the first end of the cylinder 2 to the second end, the side of the pressure roller 42 near the second end of the cylinder 2 can get closer to the cylinder 2. At this time, the angle α1 between the axial direction and the longitudinal direction of the pressure roller 42 is in the range of 0° to 35°. When the traveling frame 3 moves from the position corresponding to the second end of the cylinder 2 to the first end, the side of the pressure roller 42 near the first end of the cylinder 2 can get closer to the cylinder 2. At this time, the angle α1 between the axial direction and the longitudinal direction of the pressure roller 42 is in the range of -35° to 0°. In specific embodiments, the angle between the pressure roller 42 and the longitudinal direction can be selected as 25°, -25°, etc.
[0063] In practice, the different traveling speeds of the traveling frame 3 and the different tilt angles of the pressure roller 42 need to be matched so that the wrapping film 5 can fit more closely to the outer circumference of the cylinder 2. The greater the traveling speed of the traveling frame 3, the larger the absolute value of the angle between the axial direction and the longitudinal direction of the pressure roller 42, i.e., the larger the angle with the longitudinal direction. Conversely, the smaller the traveling speed of the traveling frame 3, the smaller the absolute value of the angle between the axial direction and the longitudinal direction of the pressure roller 42, i.e., the closer it is to being parallel to the longitudinal direction. Therefore, there is a positive correlation between the traveling speed of the traveling frame 3 and the absolute value of the angle between the pressure roller 42 and the longitudinal direction. Furthermore, the traveling speed of the traveling frame 3 and the tilt angle of the pressure roller 42 also need to be matched with the material and thickness of the wrapping film 5 to avoid excessive wrinkles or overlaps in the wrapping film 5 during the wrapping process of the cylinder 2.
[0064] Furthermore, the rotating component 431 is a bearing seat, which is connected between the bottom of the unwinding frame 4 and the traveling base 3. Specifically, the unwinding frame 4 is positioned above the traveling base 3, and the bottom of the unwinding frame 4 and the traveling base 3 are rotatably connected through the bearing seat. The rotation axis of the unwinding frame 4 extends vertically.
[0065] A positioning element is also provided between the traveling base frame 3 and the unwinding frame 4, which can lock the unwinding frame 4 and the traveling base frame 3. After the unwinding frame 4 is rotated and adjusted relative to the traveling base frame 3, the positioning element can position the unwinding frame 4 and the traveling base frame 3.
[0066] Specifically, the traveling frame 3 is provided with a horizontally positioned first adjusting plate 31. The top surface of the first adjusting plate 31 is provided with multiple positioning holes 311, which extend vertically and are arranged at intervals along an arc around the rotation center of the unwinding frame 4. The unwinding frame 4 is provided with a vertically penetrating first insertion hole 433. The positioning component includes a first pin 432. The unwinding frame 4 and the traveling frame 3 can be positioned and locked by inserting the first pin 432 into the first insertion hole 433 and any positioning hole 311 respectively. There is a certain angle between two adjacent positioning holes 311. When the unwinding frame 4 is rotated relative to the traveling frame 3, the first pin 432 can select the corresponding positioning hole 311 and insert it together with the first insertion hole 433 to complete the rapid positioning of the traveling frame 3 and the unwinding frame 4.
[0067] Furthermore, the traveling frame 3 is provided with first adjusting plates 31 on both longitudinal sides, and the unwinding frame 4 is provided with first insertion holes 433 on both opposite sides. Two first pins 432 can be inserted into the positioning hole 311 of one of the first adjusting plates 31 and the first insertion hole 433 respectively, so that there are two positioning points between the longitudinal sides of the traveling frame 3 and the unwinding frame 4, thereby improving the positioning stability between the traveling frame 3 and the unwinding frame 4.
[0068] In another embodiment, the positioning element can also be a bolt or other locking component. Furthermore, the top surface of the first adjusting plate 31 can also be provided with an arc-shaped groove, the center of which coincides with the rotation center of the unwinding frame 4. The bolt passes through the first insertion hole 433 and can slide along the arc-shaped groove as the unwinding frame 4 rotates. After the tilt angle of the unwinding roller 41 is adjusted, the bolt locks and fixes the first insertion hole 433 and the arc-shaped groove.
[0069] In some other embodiments, the rotating component 431 can be a motor or a drive combination of a motor and a gear set. The rotating component 431 is mounted on the traveling frame 3, and the rotation output end of the rotating component 431 is connected to the traveling frame 3. The angle of the unwinding frame 4 can be adjusted by electronic control to achieve automatic adjustment and improve control accuracy.
[0070] Figure 5 A structural diagram of the base frame and roller frame 45 is shown.
[0071] Combination Figure 3 and Figure 5 The unwinding frame 4 includes a base 44, a roller frame 45, and a support frame 49.
[0072] The base 44 is mounted on the traveling frame 3, and the roller frame 45 is connected to the base 44. The top of the roller frame 45 is provided with a pressure roller 42, and the bottom of the roller frame 45 is mounted on the base 44. The pressure roller 42 is rotatably connected to the roller frame 45, and the rotation axis of the pressure roller 42 coincides with the extension direction of the axis of the pressure roller 42.
[0073] Specifically, the base 44 is rotatably connected to the traveling frame 3 via a rotating component 431. A first insertion hole 433 is provided on the base 44 so that the first pin 432 can lock the base 44 to the traveling frame 3 in a fixed position.
[0074] In this application, the bottom end of the roller frame 45 is rotatably connected to the base 44, so that the top end of the roller frame 45 swings downward relative to the base 44 to drive the pressure roller 42 closer to the roller frame 1, or swings upward relative to the base 44 to drive the pressure roller 42 away from the roller frame 1. By rotating and adjusting the angle of the roller frame 45 relative to the base 44, the lateral distance between the pressure roller 42 and the cylinder 2 can be adjusted, as well as the height distance between the axis of the pressure roller 42 and the cylinder 2 can be adjusted. This not only ensures that the bottom surface of the pressure roller 42 can always adhere to the wrapping film 5, but also adjusts the tension on the wrapping film 5, so that the wrapping film 5 can further adhere to the cylinder 2 to complete the wrapping, reduce wrinkles, and improve the wrapping effect.
[0075] The roller frame 45 can swing up and down relative to the base 44, adjusting the tension of the pressure roller 42 on the wrapping film 5. This also allows the cylinder wrapping device to adapt to cylinders 2 of different diameters, improving its applicability. Specifically, given a fixed distance between the roller frame 1 and the traveling base 3, the larger the diameter of the cylinder 2, the more the roller frame 45 can rotate upward relative to the base 44, reducing the wrapping angle of the wrapping film 5 on the pressure roller 42 and preventing excessive tension on the wrapping film 5. This also prevents interference between the pressure roller 42 and the side of the cylinder 2. Conversely, the smaller the diameter of the cylinder 2, the more the roller frame 45 can rotate downward relative to the base 44, increasing the wrapping angle of the wrapping film 5 on the pressure roller 42. This prevents insufficient tension on the wrapping film 5 and allows the pressure roller 42 to be closer to the cylinder 2, reducing wrinkles during the wrapping process. As can be seen, in this embodiment, the rotation angle of the roller frame 45 relative to the base 44 and the tension of the wrapping film 5 on the pressure roller 42 can be considered to be positively correlated.
[0076] In this embodiment, the angle between the roller frame 45 and the horizontal plane is adjustable within the range of 0° to 90°. When the angle between the roller frame 45 and the horizontal plane is 90°, the roller frame 45 is perpendicular to the base frame. In a specific embodiment, the diameter of the cylinder 2 is between 2000mm and 2500mm, the angle between the roller frame 45 and the horizontal plane is between 35° and 50°, and the horizontal distance between the pressure roller 42 and the side of the cylinder 2 closest to the pressure roller 42 is between 1600mm and 1900mm.
[0077] Furthermore, the roller frame 45 is rotatably connected to the base 44 via a rotating shaft. A locking element is provided between the roller frame 45 and the base 44, which can lock the roller frame 45 and the base 44 in place.
[0078] Specifically, the base 44 is provided with a vertically arranged second adjusting plate 441. The side of the second adjusting plate 441 has multiple locking holes 4411, which are arranged sequentially at intervals along an arc around the rotation center of the roller frame 45. That is, the center of the arc along the direction of the multiple locking holes 4411 coincides with the rotation center of the roller frame 45. The roller frame 45 has a horizontally extending second insertion hole. The locking element includes a second pin 46. The roller frame 45 and the base 44 can be positioned and locked by correspondingly inserting the second pin 46 into the second insertion hole and any one of the locking holes 4411. Adjacent locking holes 4411 differ by a certain angle. When the roller frame 45 rotates relative to the base 44, the second pin 46 can select the corresponding locking hole 4411 and insert it together with the second insertion hole, thereby completing the rapid positioning of the base 44 and the roller frame 45.
[0079] In addition, the locking element can also be a bolt structure. Alternatively, the side of the second adjusting plate 441 can also be provided with an arc-shaped groove, the center of which coincides with the rotation center of the roller frame 45. The bolt passes through the second insertion hole and can slide along the arc-shaped groove. After the rotation angle of the roller frame 45 relative to the base 44 is adjusted, the bolt can lock and fix the second insertion hole and the arc-shaped groove.
[0080] The roller frame 45 of this application is rotatably connected to the second adjusting plate 441.
[0081] Specifically, the roller frame 45 includes two spaced-apart mounting arms and multiple connecting arms connecting the two mounting arms. The two ends of the shaft of the pressure roller 42 are rotatably connected to the two mounting arms, improving the installation and stability of the pressure roller 42. Two second adjusting plates 441 are respectively disposed on the outer sides of the two mounting arms, and the two mounting arms are rotatably connected to the two second adjusting plates 441 respectively. Second insertion holes are provided on the outer surface of the mounting arms, facilitating the second pin 46 to pass through the locking hole 4411 on the second adjusting plate 441 and be inserted into the second insertion hole.
[0082] Furthermore, the roller frame 45 is equipped with an adjusting roller 473, which is located below the pressure roller 42. The adjusting roller 473 is parallel to the pressure roller 42 and is spaced apart on one side of the pressure roller 42, so that the wrapping film 5 first adheres to the adjusting roller 473 and then extends to the pressure roller 42. The space between the pressure roller 42 and the adjusting roller 473 is the conveying space 421. Specifically, the wrapping film 5 first adheres to the upper surface of the adjusting roller 473 and then to the lower surface of the pressure roller 42 to complete an S-shaped sequential wrapping. The setting of the adjusting roller 473 ensures that the wrapping film 5 can always wrap around the lower surface of the pressure roller 42 for conveying, ensuring the tension of the wrapping film 5. In addition, by adjusting the rotation angle of the roller frame 45 relative to the base 44, the pressure roller 42 and the adjusting roller 473 can be simultaneously adjusted in terms of vertical position and lateral position relative to the cylinder 2.
[0083] Furthermore, a connecting seat 47 is provided on the top of the roller frame 45, and the pressure roller 42 and the adjusting roller 473 are disposed on the connecting seat 47. The connecting seat 47 is rotatably connected to the top of the roller frame 45 so that the connecting seat 47 can drive the pressure roller 42 and the adjusting roller 473 to swing up and down relative to the roller frame 45.
[0084] The connecting seat 47 can rotate relative to the roller frame 45, allowing for further fine-tuning of the spatial positions of the pressure roller 42 and the adjusting roller 473. This enables precise adjustment of the tension of the pressure roller 42 and the adjusting roller 473 on the wrapping film 5, ensuring that the conveyed wrapping film 5 remains unfolded and reducing wrinkles caused by excessive tension. In this application, the rotation axis of the connecting seat 47 is parallel to the rotation axis of the roller frame 45. Rotating the connecting seat 47 allows for simultaneous adjustment of the vertical positions of the pressure roller 42 and the adjusting roller 473, as well as the distance between them and the cylinder 2.
[0085] Specifically, the connecting seat 47 includes a first roller arm 471 and a second roller arm 472 connected in sequence. A pressure roller 42 is located at the end of the first roller arm 471 away from the second roller arm 472, and an adjusting roller 473 is located at the end of the second roller arm 472 away from the first roller arm 471. The first roller arm 471 and the second roller arm 472 are fixed to each other, allowing them to rotate synchronously relative to the roller frame 45. Specifically, the first roller arm 471 and the second roller arm 472 can be integrally formed or fixed by welding, bolting, or other methods. The pressure roller 42 is mounted on the first roller arm 471, and the adjusting roller 473 is mounted on the second roller arm 472. By rotating the connecting seat 47 relative to the roller frame 45, both the pressure roller 42 and the adjusting roller 473 can be moved with the connecting seat 47 simultaneously. The rotation axis of the connecting seat 47 can be located between or outside the pressure roller 42 and the adjusting roller 473, or it can coincide with the axial extension direction of the pressure roller 42 or the adjusting roller 473.
[0086] Furthermore, the included angle between the first roller arm 471 and the second roller arm 472 is an obtuse angle. Controlling the wrapping film 5 to a certain discharge angle is beneficial for the discharge of the wrapping film 5. In addition, the wrapping film 5 is discharged sequentially around the adjusting roller 473 and the pressure roller 42. The included angle between the first roller arm 471 with the pressure roller 42 and the second roller arm 472 with the adjusting roller 473 is an obtuse angle, which can reduce the wrapping angle of the wrapping film 5 between the adjusting roller 473 and the pressure roller 42, and reduce the tension of the wrapping film 5.
[0087] Furthermore, the adjusting roller 473 is located on the side of the roller frame 45 facing away from the roller frame 1. The discharge end of the wrapping film 5 can be closer to the cylinder 2, which facilitates the discharge of the wrapping film 5.
[0088] Specifically, the included angle between the first roller arm 471 and the second roller arm 472 is an obtuse angle and the opening faces upward. The adjusting roller 473 is located on the side of the pressure roller 42 away from the roller frame 1, which reduces the wrapping angle of the wrapping film 5 between the adjusting roller 473 and the pressure roller 42, reduces the tension of the wrapping film 5, reduces the risk of deformation of the wrapping film 5, and facilitates the flat discharge of the wrapping film 5.
[0089] In this application, the rotation center of the connecting seat 47 is located between the pressure roller 42 and the adjusting roller 473. The cylinder 2 is higher than the pressure roller 42, and the wrapping film 5 travels from the lower side of the pressure roller 42 to the upper side of the cylinder 2. By rotating the connecting seat 47, the pressure roller 42 can be lowered and the adjusting roller 473 can be raised to increase the tension on the wrapping film 5, or the pressure roller 42 can be raised and the adjusting roller 473 can be lowered to decrease the tension on the wrapping film 5.
[0090] Specifically, a first rotating shaft 474 is provided between the first roller arm 471 and the second roller arm 472, and the first rotating shaft 474 is rotatably connected to the top of the roller frame 45. In practice, two connecting seats 47 are spaced apart, with each end of the pressure roller 42 and each end of the adjusting roller 473 rotatably connected to one of the two connecting seats 47. The pressure roller 42 and the adjusting roller 473 can be connected to the connecting seats 47 via bearings or other components. The outer walls of the two connecting seats 47 are rotatably connected to the two mounting arms of the roller frame 45 via the first rotating shaft 474. A retaining spring can be fitted onto the first rotating shaft 474, located on the outside of the mounting arm, to ensure that the connecting seat 47 is stably mounted on the mounting arm.
[0091] The connecting seat 47 can be manually adjusted, such as by the engagement of the locking structure and the hole, to achieve relative rotation and fixation with the roller frame 45. Alternatively, the connecting seat 47 can be automatically adjusted, such as by a motor, cylinder, or other driving component, to achieve relative rotation with the roller frame 45.
[0092] In this embodiment, a telescopic drive member 48 is provided on the roller frame 45. The drive end of the telescopic drive member 48 is connected to the connecting seat 47. The telescopic drive member 48 is configured to drive the connecting seat 47 to swing up and down relative to the roller frame 45. Specifically, the telescopic drive member 48 is rotatably connected to the roller frame 45, and the drive end of the telescopic drive member 48 is rotatably connected to the connecting seat 47 to avoid motion interference. The telescopic drive member 48 can be a cylinder or a manual cylinder, etc.
[0093] At least one first tension roller 451 is provided between the top and bottom ends of the roller frame 45, and the first tension roller 451 extends in the horizontal direction. The axial extension directions of the first tension roller 451, the adjusting roller 473, and the pressure roller 42 are parallel to each other. The wrapping film 5 can be wrapped around the tension roller, the adjusting roller 473, and the pressure roller 42 in sequence. The first tension roller 451 is used to confine the wrapping film 5 in the space between the first tension roller 451 facing away from or towards the roller frame 1, so as to complete the wrapping film 5 wrapping the first tension roller 451.
[0094] Figure 3 In the embodiment shown, there are two first tension rollers 451, which are spaced apart along the direction between the top and bottom of the roller frame 45.
[0095] In other embodiments, the wrapping film 5 may be selected to either pass around the first tension roller 451 and the number of first tension rollers 451 passed around, depending on the required tension.
[0096] In addition, both ends of the first tension roller 451 are rotatably connected to the two mounting arms, which improves the installation and stability of the first tension roller 451.
[0097] Furthermore, the unwinding frame 4 also includes a support frame 49 disposed on the base 44, and the unwinding roller 41 is detachably disposed on the top of the support frame 49, facilitating the replacement and installation of the wrapping film 5 from the unwinding roller 41. The support frame 49 and the roller frame 45 are arranged laterally at intervals, and the unwinding roller 41 is located on the side of the pressure roller 42 facing away from the roller frame 1. The unwinding roller 41, the pressure roller 42, and the cylinder 2 are arranged sequentially laterally, facilitating the sequential conveying of the wrapping film 5 from the unwinding roller 41 to the pressure roller 42, and from the pressure roller 42 to the cylinder 2.
[0098] Specifically, the support frame 49 includes two spaced-apart support arms, with each end of the unwinding roller 41 rotatably connected to a support arm to improve the installation stability of the unwinding roller 41. A connecting beam is also connected between the two support arms to enhance the strength of the support frame 49.
[0099] The support frame 49 and the roller frame 45 are both mounted on the base 44, and can adjust the angle between the pressure roller 42 and the unwinding roller 41 and the longitudinal direction as the base 44 rotates.
[0100] Figure 6 A schematic diagram of the installation of the unwinding frame 4 is shown.
[0101] Reference Figure 3 and Figure 6 Furthermore, the top of the support frame 49 is provided with a fixed seat 491, and the top of the fixed seat 491 is provided with an upward-facing lower fixing groove 4911, into which the axial end of the unwinding roller 41 can be inserted downward. A movable seat 492 is detachably provided on the fixed seat 491, and the bottom of the movable seat 492 is provided with a downward-facing upper fixing groove 4921. The upper fixing groove 4921 and the lower fixing groove 4911 together form a fixing hole 493, to which the unwinding roller 41 is rotatably connected.
[0102] After the movable seat 492 is installed on the fixed seat 491, the upper fixing groove 4921 of the movable seat 492 and the lower fixing groove 4911 of the fixed seat 491 communicate with each other to form a fixing hole 493, thereby locking the unwinding roller 41 onto the support frame 49. The unwinding roller 41 can be rotatably connected to the fixing hole 493, reducing the rotational friction of the unwinding roller 41 and facilitating the unwinding of the wrapping film 5. When it is necessary to replace the roll of wrapping film 5 on the unwinding roller 41, the unwinding roller 41 can be removed by disassembling the movable seat 492 from the fixed seat 491.
[0103] The lower fixing groove 4911 in this embodiment includes a vertical portion and a lower arc portion. The top end of the vertical portion extends upward to the top surface of the fixing seat 491 to form an opening, and the bottom end of the vertical portion connects downward to the lower arc portion. The lower arc portion forms a semi-circular bottom surface, with the arc center facing upward toward the vertical portion. The vertically extending portion of the lower fixing groove 4911 facilitates the positioning of the unwinding roller 41. The fixing seat 491 has mounting surfaces on both sides corresponding to the position where the vertical portion is located, facilitating the connection and installation of the fixing seat 491 and the movable seat 492.
[0104] In this embodiment, the upper fixing groove 4921 includes an upper arc portion with the center of the arc facing downwards. The bottom side of the upper arc portion extends downwards to the bottom surface of the movable seat 492 to form an opening. When the movable seat 492 is installed on the fixed seat 491, the upper arc portion and the lower arc portion communicate with each other to form a fixing hole 493, and the shape fits more closely to the unwinding roller 41.
[0105] Furthermore, at least three rolling wheels 494 are provided between one or both of the fixed seat 491 and the movable seat 492. The rolling wheels 494 are arranged circumferentially around the fixed hole 493 and abut against the outer periphery of the unwinding roller 41. After the unwinding roller 41 is locked in the fixed hole 493, at least three rolling wheels 494 can support the outer periphery of the unwinding roller 41, and the rolling surface of the rolling wheels 494 abuts against the outer periphery of the unwinding roller 41. At least three rolling wheels 494 can determine the installation position of the unwinding roller 41, realize the spatial positioning of the unwinding roller 41, and at the same time, do not affect the rolling of the unwinding roller 41, ensuring the smooth unwinding of the wrapping film 5.
[0106] In practice, the rollers 494 can be all mounted on the fixed base 491, all mounted on the movable base 492, or mounted on both the fixed base 491 and the movable base 492. There can be three or four rollers 494. The three rollers 494 can be of the same size, or they can be of different sizes to allow for space planning.
[0107] In this embodiment, two rolling wheels 494 are provided on both sides of the lower fixing groove 4911 on the fixed base 491, and the unwinding roller 41 is located between the two rolling wheels 494 on the fixed base 491. A rolling wheel 494 is provided at the top of the upper fixing groove 4921 on the movable base 492, and the unwinding roller 41 is located at the bottom of the rolling wheel 494 on the movable base 492. After the movable base 492 is installed on the fixed base 491, the three rolling wheels 494 are arranged in an array on the outer periphery of the unwinding roller 41. The rolling wheels 494 can be rollers or bearings, etc.
[0108] The rolling wheel 494 protrudes from the inner wall of the fixing hole 493 near the fixing hole 493 to abut against the outer periphery of the unwinding roller 41. In some specific embodiments, the rolling wheel 494 is disposed on the side wall of the fixing seat 491 and / or the lower fixing seat 491, with the side of the rolling wheel 494 near the fixing hole 493 protruding from the inner wall of the fixing hole 493 to abut against the outer periphery of the unwinding roller 41. In other embodiments, the rolling wheel 494 may also be embedded in the lower fixing groove 4911 and / or the upper fixing groove 4921, such that the rolling wheel 494 is formed in the inner periphery of the fixing hole 493 and slightly protrudes from the inner wall of the fixing hole 493, with multiple rolling wheels 494 abutting against the outer periphery of the unwinding roller 41.
[0109] like Figure 6 In the illustrated embodiment, the fixed seat 491 has lower fixing holes 493 on both sides of the lower fixing groove 4911, and the movable seat 492 has upper fixing holes 493 on both sides of the upper fixing groove 4921. The spacing between the two lower fixing holes 493 and the spacing between the two upper fixing holes 493 are matched. A third pin 495 can be inserted between a set of matched lower fixing holes 493 and upper fixing holes 493. The fixed seat 491 and the movable seat 492 are inserted into the lower fixing holes 493 and upper fixing holes 493 respectively through the two third pins 495 to achieve quick positioning. When it is necessary to disassemble the unwinding roller 41, any one of the third pins 495 can be removed, and the other third pin 495 can be used as a rotation shaft for the movable seat 492 to rotate relative to the fixed seat 491. By flipping the movable seat 492, the opening of the lower fixing groove 4911 of the fixed seat 491 can be quickly opened, which is convenient for the staff to disassemble the unwinding roller 41 and replace the wrapping film 5. After the wrapping film 5 is replaced, the movable seat 492 can be reinstalled by flipping the movable seat 492 back onto the fixed seat 491 and inserting the removed third pin 495 back in, thereby improving the efficiency of disassembly and assembly of the movable seat 492.
[0110] In some other embodiments, the fixed base 491 and the movable base 492 can also be detachably installed by bolts.
[0111] Furthermore, a second tension roller 496 is provided on the support frame 49. The second tension roller 496 is located below the unwinding roller 41 and is used for wrapping the wrapping film 5.
[0112] In addition, the support frame 49 may be equipped with a pressing device, which includes a pressing rod and a pressing roller mounted on the pressing rod. One end of the pressing rod is connected to the support frame 49, and the rolling surface of the pressing roller is always pressed against the outside of the wrapping film roll to prevent the wrapping film roll from unraveling. The pressing rod can be connected to the support frame 49 by a reset structure such as a torsion spring to keep the pressing roller always pressed against the outside of the wrapping film roll.
[0113] Furthermore, the base 44 is also provided with at least one third tension roller 442, which is spaced apart between the roller frame 45 and the support frame 49. The third tension roller 442 is used for wrapping the wrapping film 5. In this embodiment, there are two third tension rollers 442, which are spaced apart laterally. The third tension roller 442 is located between the second tension roller 496 and the first tension roller 451. In addition, a tension sensor may also be provided on the third tension roller 442 to accurately detect the tension of the wrapping film 5.
[0114] In this application, the wrapping film 5 is fed downwards from the unwinding roller 41 on the side facing away from the roller frame 1. Then, depending on the material and thickness of the wrapping film 5 and the required tension, one or more of the second tensioning roller 496, the third tensioning roller 442, and the first tensioning roller 451 are selected in sequence for winding around it. The second tensioning roller 496, the third tensioning roller 442, and the first tensioning roller 451 are all located below the pressure roller 42 and the adjusting roller 473. That is, the wrapping film 5 can also bypass the second tensioning roller 496, the third tensioning roller 442, and the first tensioning roller 451 respectively. The wrapping film 5 then passes over the upper side of the adjusting roller 473, and finally passes over the lower side of the pressure roller 42 before winding upwards to the upper side of the cylinder 2.
[0115] Figure 7 The diagram shows the steps of using the cylinder wrapping device. (Refer to...) Figure 7 The method of using the cylinder wrapping device applies to the aforementioned cylinder wrapping device. The method of using the cylinder wrapping device includes the following steps:
[0116] S10. Determine the traveling speed of the traveling frame 3 based on the width of the wrapping film 5, the preset overlap width of the wrapping, and the time it takes for the cylinder 2 to rotate one revolution.
[0117] In some embodiments, the walking speed is calculated as (width of the bandage film 5 - preset overlap width) / time taken for the cylinder 2 to rotate one revolution. Specifically, the preset overlap width can be considered as the overlap width between two adjacent bandage films 5, and can be ignored in actual calculations. The time taken for the cylinder 2 to rotate one revolution can be determined based on the rotational speed of the cylinder 2. In some specific embodiments, the rotational speed of the cylinder 2 is 0.9 r / min, the width of the bandage film is 1 meter, and the walking speed is approximately 15 mm / s.
[0118] S20. Pull the wrapping film 5 out from the conveying space 421 below the pressure roller 42, flatten it and stick it to one axial end surface of the cylinder 2.
[0119] Before the wrapping film 5 is pulled out from the output space below the pressure roller 42, the pressure roller 42 is set at an inclination in the longitudinal direction. The pressure roller 42 extends towards the other end of the cylinder 2 in a direction that gradually approaches the cylinder 2.
[0120] S30, drive the cylinder 2 to rotate, and the traveling frame 3 moves along the track 33 toward the other end of the cylinder 2 along the axial direction at a traveling speed. The roller frame 1 can drive the cylinder 2 to rotate at a certain speed.
[0121] S40. The traveling frame 3 moves to the other end of the cylinder 2 and stops, and the cylinder 2 stops rotating. After the wrapping film 5 completes one wrapping of the outer circumference of the cylinder 2, the traveling frame 3 and the cylinder 2 are stopped.
[0122] S50, cut the wrapping film 5 between the pressure roller 42 and the cylinder 2.
[0123] Furthermore, the method of using the cylinder wrapping device also includes the following steps:
[0124] S60, the unwinding frame 4 can rotate relative to the traveling base frame 3. After "cutting the wrapping film 5 from the pressure roller 42 to the cylinder 2", the unwinding frame 4 is rotated to adjust the angle between the axial extension direction of the pressure roller 42 and the longitudinal direction to the opposite angle.
[0125] The reverse angle can be understood as the side of the pressure roller 42 facing one end of the cylinder 2 extending towards the cylinder 2 in a direction that gradually approaches the cylinder 2. Specifically, during the process of the traveling frame 3 moving from one end of the cylinder 2 to the other end of the cylinder 2, the angle between the axial direction and the longitudinal direction of the pressure roller 42 is between 0° and 35°. During the process of the traveling frame 3 returning from the other end of the cylinder 2 to one end of the cylinder 2, the angle between the axial direction and the longitudinal direction of the pressure roller 42 is between -35° and 0°.
[0126] S70. Pull the wrapping film 5 out from the pressure roller 42 again, flatten it and stick it to the wrapping film 5 covering the other end surface of the cylinder 2.
[0127] S80, drive the cylinder 2 to rotate, and the traveling frame 3 moves back along the track 33 from the other end of the cylinder 2 along the axial direction at the traveling speed.
[0128] S90. The traveling frame 3 moves to the other end of the cylinder 2 and stops, and the cylinder 2 stops rotating. After the wrapping film 5 finishes wrapping the cylinder 2 again, the traveling frame 3 and the cylinder 2 are stopped.
[0129] S100, cut the wrapping film 5 between the pressure roller 42 and the cylinder 2.
[0130] S110. Repeat the above steps until the number of layers of wrapping film 5 covering the surface of cylinder 2 meets the preset requirements.
[0131] In addition, the method of using the cylinder wrapping device also includes the following steps:
[0132] S11. Before “pulling the wrapping film 5 out from the conveying space 421 below the pressure roller 42, flattening it and sticking it to one axial end surface of the cylinder 2”, the wrapping film 5 needs to be wound on the unwinding frame 4 first. Specifically, the winding process of the wrapping film 5 on the unwinding frame 4 is as follows: the wrapping film 5 is first unwound from the unwinding roller 41, and then selected to wind around one or more of the second tension roller 496, the third tension roller 442, and the first tension roller 451 in sequence. Then it winds around the upper side of the adjusting roller 473, and finally winds upward to the upper side of the cylinder 2 after passing the lower side of the pressure roller 42.
[0133] The unwinding frame 4 includes a roller frame 45, with a pressure roller 42 at the top and the bottom of the roller frame 45 rotatably connected to the base 44. During the winding process of the wrapping film 5 on the unwinding frame 4, the roller frame 45 is rotated and positioned relative to the base 44, thereby adjusting to the required tension of the wrapping film 5.
[0134] Furthermore, S12, the top of the roller frame 45 is provided with a connecting seat 47, the pressure roller 42 and the adjusting roller 473 are set on the connecting seat 47, the connecting seat 47 is rotatably connected to the top of the roller frame 45, during the process of winding the wrapping film 5 on the unwinding frame 4, the connecting seat 47 is rotated relative to the roller frame 45, thereby adjusting to the tension required for the wrapping film 5.
[0135] The method of using the cylinder wrapping device of this application is to drive the longitudinally inclined pressure roller 42 to move longitudinally through the traveling base frame 3, thereby conveying the wrapping film 5 from the pressure roller 42 to the cylinder 2 extending longitudinally to complete continuous wrapping, reducing the number of joints of the wrapping film 5, and making the wrapping film 5 fit the surface of the cylinder 2 more closely, thereby reducing the wrinkles of the wrapping film 5 wrapped on the outer surface of the cylinder 2.
[0136] Furthermore, by controlling the walking speed of the walking frame 3, the misalignment between adjacent two layers of wrapping film 5 can be effectively controlled, thereby improving the wrapping tightness of the wrapping material on the surface of the cylinder 2 and improving the wrapping quality.
[0137] In fact, the angle between the pressure roller 42 and the longitudinal direction, the rotation speed of the cylinder 2, the walking speed of the walking base 3, and the width of the wrapping film 5 can all be adjusted according to different products and different raw materials.
[0138] During the production process, the traveling frame 3 can move back and forth along the longitudinal direction. At the same time, the unwinding frame 4 drives the pressure roller 42 to adjust the angle between itself and the longitudinal direction during the reciprocating movement of the traveling frame 3, thereby completing the multi-layer wrapping of the outer surface of the cylinder 2 and improving production efficiency.
