Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of Dewar bottle processing equipment, specifically a vertical winding machine for the protective layer of Dewar bottles. Background Technology
[0002] As the core equipment for liquid gas storage, the insulation performance of the Dewar flask directly determines the storage efficiency and safety of the liquid gas. The key to the insulation performance depends on the quality of the insulation material covering the outer layer of the inner liner. Currently, composite aluminum foil and other insulation materials are generally wrapped onto the surface of the inner liner of the Dewar flask using a winding machine.
[0003] A published Chinese patent, CN208764657U, discloses a vertical winding machine, including a base with a support on the base and a lifting motor fixed at the top of the support. A guide rail is provided on the support, and a slider moves up and down along the guide rail under the control of the lifting motor. A Dewar flask rotation motor is fixed on the slider, and a Dewar flask is suspended below the Dewar flask rotation motor. The Dewar flask rotation motor provided in this patent lacks an adjustment mechanism for adjusting the horizontal position of the Dewar flask. This results in the machine being unable to flexibly adjust the horizontal axis position of the Dewar flask when dealing with Dewar flasks of different diameters. When processing Dewar flasks with larger or smaller diameters, their axis will horizontally offset from the wrapping center, preventing the insulation material from evenly adhering to the flask surface during the winding process. Utility Model Content
[0004] The purpose of this invention is to provide a vertical winding machine for the protective layer of Dewar bottles, so as to solve the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a vertical winding machine for Dewar bottle protective layer, including a base, a column fixed on the base, a winding mechanism in the middle of the column, a lifting mechanism at the top of the column, and a rotating mechanism on the lifting mechanism; The rotating mechanism is equipped with an adjustment mechanism, which includes a first guide rail and a first motor arranged parallel to each other on both sides. A plurality of first sliders are slidably fitted on the first guide rail. A first mounting plate is fixedly mounted on the top of the first slider, and a first ball bearing seat is fixedly mounted on the bottom of the first mounting plate. A first lead screw is threaded through the inner thread of the first ball bearing seat. One end of the first lead screw is connected to the output end of the first motor, and the other end of the first lead screw is connected to a first limit seat. The first motor drives the first lead screw to rotate, thereby causing the first ball bearing seat and the first mounting plate to move horizontally, so as to adjust the horizontal axis position of the rotating mechanism and the Dewar flask.
[0006] In one embodiment of the present invention, the winding mechanism includes a bracket, a second motor, a first gearbox, a rotary arm, an upper roller assembly, and a lower roller assembly. The second motor and the first gearbox are both fixed on the bracket. The output end of the second motor is connected to the first gearbox, and the output end of the first gearbox is connected to the rotary arm. The upper roller assembly and the lower roller assembly are respectively located at the upper and lower ends of the rotary arm.
[0007] In one embodiment of this utility model, the lifting mechanism includes a second mounting plate, on which a third motor and a second reduction gearbox are fixedly mounted. The output end of the third motor is connected to the second reduction gearbox, and the output end of the second reduction gearbox is connected to a second lead screw. The other end of the second lead screw is connected to a second limit seat, and a second ball bearing seat is threaded onto the second lead screw. A cantilever frame is fixedly mounted on the top surface of the second ball bearing seat. The column is fixedly mounted on the two sides of the cantilever frame with second guide rails. Multiple second sliders are slidably fitted on the second guide rails, and the second sliders are fixedly mounted on the two sides of the bottom surface of the cantilever frame.
[0008] In one embodiment of the present invention, the rotating mechanism includes a fourth motor and a third gearbox. The fourth motor and the third gearbox are fixed on a first mounting plate, and the output end of the fourth motor is connected to the third gearbox. The output end of the third gearbox is connected to a drive shaft, and the other end of the drive shaft is provided with an adjusting shaft. The other end of the adjusting shaft is connected to a Dewar flask.
[0009] In one embodiment of this utility model, both the upper roller assembly and the lower roller assembly include a working cylinder and a spare cylinder.
[0010] In one embodiment of this utility model, a plurality of fixing ribs are provided between the base and the column.
[0011] Compared with the prior art, the beneficial effects achieved by this utility model are: (1) By setting an adjustment mechanism, the first motor in the adjustment mechanism drives the first lead screw to rotate, which can drive the first ball seat and the first mounting plate to move horizontally along the first guide rail, thereby adjusting the horizontal position of the rotating mechanism and the Dewar bottle. Without disassembling or replacing parts, it can be adapted to Dewar bottles of different diameters, ensuring that the axis of the Dewar bottle of different specifications is aligned with the winding center point of the winding mechanism, avoiding the problem of deviation in the interlayer gap when the insulation material is wound, so that the protective layer of the bottle can be evenly attached to the bottle body, laying a good foundation for subsequent processes; (2) By setting up a winding mechanism with upper and lower roller groups, when the insulation material on the working cylinder is about to run out, there is no need to stop the machine to replace it. It can be directly switched to the spare cylinder to continue the winding operation. At the same time, the lifting mechanism drives the Dewar bottle to rise and fall stably, and the rotating mechanism drives the Dewar bottle to rotate at a constant speed, forming a collaborative working mode with adjustable horizontal position, stable up and down lifting, uniform rotation of the bottle body and rapid material switching, so that the winding tension of the insulation material is always stable, and the coating quality is further optimized.

[0013] To enable those skilled in the art to better understand the present invention, the solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0014] This utility model provides a technical solution: a vertical winding machine for Dewar flask protective layer, including a base 10, a column 11 fixedly mounted on the base 10, a winding mechanism 20 provided in the middle of the column 11, the winding mechanism 20 including a bracket 21, a second motor 22, a first reduction gearbox 23, a rotary arm 24, an upper roller assembly 25, and a lower roller assembly 26. The second motor 22 and the first reduction gearbox 23 are both fixedly mounted on the bracket 21, the output end of the second motor 22 is connected to the first reduction gearbox 23, and the output end of the first reduction gearbox 23 is connected to the rotary arm 24. The upper roller assembly 25 and the lower roller assembly 26 are respectively provided with... At both ends of the rotary arm 24; by adding a first reduction gearbox 23 between the second motor 22 and the rotary arm 24, the output speed of the second motor 22 can be precisely controlled, avoiding the rotary arm 24 from rotating too fast due to excessive motor output speed, which would cause a sudden increase in the winding tension of aluminum foil and cotton paper, resulting in tearing or wrinkling. The upper roller group 25 and the lower roller group 26 form a symmetrical material supply structure. Since the upper and lower ends of the rotary frame are respectively provided with three installation positions, the distance between the upper roller group 25 and the lower roller group 26 can be adjusted according to the height specifications of the Dewar bottle. A lifting mechanism 30 is provided at the top of the column 11. The lifting mechanism 30 includes a second mounting plate 31. A third motor 32 and a second reduction gearbox 33 are fixed on the second mounting plate 31. The output end of the third motor 32 is connected to the second reduction gearbox 33. A second lead screw 34 is connected to the output end of the second reduction gearbox 33. A second limit seat 35 is connected to the other end of the second lead screw 34. A second ball bearing seat 36 is threaded on the second lead screw 34. A cantilever frame 37 is fixed on the top surface of the second ball bearing seat 36. Second guide rails 38 are fixed on both sides of the cantilever frame 37 of the column 11. The column 11 slides on the second guide rails 38. Multiple second sliders 39 are fixed on both sides of the bottom surface of the cantilever frame 37. Through the cooperation of the third motor 32 and the second reduction gearbox 33, the rotation speed of the second lead screw 34 can be precisely controlled, thereby achieving precise control of the lifting speed of the second ball bearing seat 36 and the cantilever frame 37, accurately delivering the Dewar bottle to the designated winding height. The second guide rails 38 on both sides of the column 11 and the second sliders 39 on the ground of the cantilever frame 37 form a symmetrical guide structure, which can effectively limit the horizontal deviation of the cantilever frame 37 during the lifting process and avoid sliding or tilting due to unilateral force.
[0015] The lifting mechanism 30 is equipped with a rotating mechanism 40, which includes a fourth motor 41 and a third reduction gearbox 42. The fourth motor 41 and the third reduction gearbox 42 are fixed on the first mounting plate 54, and the output end of the fourth motor 41 is connected to the third reduction gearbox 42. The output end of the third reduction gearbox 42 is connected to a transmission shaft 43. The other end of the transmission shaft 43 is equipped with an adjusting shaft 44, and the other end of the adjusting shaft 44 is connected to the Dewar flask. The power of the fourth motor 41 is buffered and speed-changed by the third reduction gearbox 42 and then transmitted to the transmission shaft 43. The rotation of the transmission shaft 43 drives the adjusting shaft 44 and the Dewar flask to rotate at a constant speed, so that the insulation material adheres to the surface of the flask in a constant spiral cross-section, reducing the interlayer overlap gap. The rotating mechanism 40 is equipped with an adjusting mechanism 50, which includes a first guide rail 51 arranged parallel on both sides and a first motor 52. Multiple first sliders 53 are slidably fitted on the first guide rail 51. A first mounting plate 54 is fixed to the top of each first slider 53, and a first ball bearing seat 55 is fixed to the bottom of the first mounting plate 54. A first lead screw 56 is threaded through the internal thread of the first ball bearing seat 55. One end of the first lead screw 56 is connected to the output end of the first motor 52, and the other end of the first lead screw 56 is connected to a first limit seat 57. The first motor 52 drives the first lead screw 56 to rotate. The first ball bearing seat 55 and the first mounting plate 54 are moved horizontally to adjust the horizontal axis position of the rotating mechanism 40 and the Dewar flask. The first motor 52 drives the first lead screw 56 to rotate, which in turn causes the first ball bearing seat 55 and the first mounting plate 54 to slide smoothly along the first guide rail 51. This precisely adjusts the horizontal axis position of the rotating mechanism 40 and the Dewar flask. For Dewar flasks of different diameters in the industry, no disassembly or replacement of equipment is required; axis calibration can be completed solely through motor drive, ensuring that the axis of different Dewar flask sizes is always aligned with the wrapping center of the winding mechanism 20. Multiple fixing ribs 12 are provided between the base 10 and the column 11. These fixing ribs 12 form a triangular support structure, effectively distributing the vertical load and horizontal force borne by the column 11.
[0016] Working principle: First, according to the diameter specifications of the Dewar bottle to be processed, the adjustment mechanism 50 is started, and the first motor 52 drives the first lead screw 56 to rotate. Because the first ball seat 55 is threadedly engaged with the first lead screw 56, and the first mounting plate 54 is slidably limited by the first slider 53 and the first guide rail 51, the rotation of the first lead screw 56 is converted into the horizontal linear movement of the first mounting plate 54, which in turn drives the rotating mechanism 40 fixed on the first mounting plate 54 to move synchronously until the horizontal axis of the Dewar bottle is aligned with the covering center of the winding mechanism 20. Subsequently, the output power of the third motor 32 of the lifting mechanism 30 is reduced in speed by the second reduction gearbox 33 and drives the second lead screw 34 to rotate. Because the second ball seat 36 is threadedly engaged with the second lead screw 34, and the wall frame 37 is slidably limited by the second slider 39 and the second guide rails 38 on both sides of the column 11, the rotation of the second lead screw 34 is converted into the vertical lifting of the wall frame 37, which drives the rotating mechanism 40 and the Dewar bottle to move synchronously, thus completing the vertical positioning of the Dewar bottle. Subsequently, the power output of the fourth motor 41 is adjusted by the speed of the third reduction gearbox 42 and then transmitted to the drive shaft 43. The drive shaft 43 drives the adjustment shaft 44 and the Dewar bottle to rotate at a constant speed. Meanwhile, the second motor 22 in the winding mechanism 20 outputs power, which is reduced and increased in torque by the first reduction gearbox 23, and drives the rotary arm 24 to rotate at a constant speed around the Dewar bottle axis. During the rotation of the rotary arm 24, the upper roller group 25 and the lower roller group 26 rotate synchronously, alternately stacking the aluminum foil and cotton paper on the rollers onto the surface of the rotating Dewar bottle.
