Description

Technical Field

[0001] This utility model relates to the field of tobacco production technology, and in particular to a tube lifting device and tube-type equipment. Background Technology

[0002] Roller-type equipment (such as hot air leaf moistening machines) in tobacco leaf re-drying production lines are key pieces of equipment in the tobacco processing process, and their performance and operating status directly affect the economic benefits of enterprises. These machines typically employ an inclined rotating cylinder structure, with the cylinder supported by multiple sets of rollers and rotating via friction transmission. Currently, a rolling ring is formed on the outer circumference of the cylinder, and the entire weight of the cylinder is supported by the rollers. A line contact friction pair is formed between the rollers and the rolling ring, which serves both a supporting function and power transmission.

[0003] Whether the equipment is running or stopped, the weight of the cylinder is always applied to the same contact area of ​​the support rollers and the rolling ring through line contact. This continuous concentrated load causes plastic deformation at the contact points, resulting in uneven surface defects. Once the roundness of the support rollers and rolling ring is compromised, periodic vibrations will occur during cylinder rotation, severely affecting the stability of the equipment. Especially in inclined equipment such as hot air dehumidifiers, excessive cylinder vibration can exacerbate axial movement, even causing equipment damage and production accidents.

[0004] Therefore, there is an urgent need for a cylinder lifting device and cylinder-type equipment to solve the above-mentioned technical problems. Utility Model Content

[0005] One objective of this invention is to provide a cylinder lifting device that can ensure the roundness of the support rollers and the cylinder.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] The cylinder lifting device includes:

[0008] The support assembly includes a connecting frame arranged in a horizontal direction, and a first top block and a second top block spaced apart on the connecting frame. The first top block and the second top block are used to jointly support the outer peripheral surface of the cylinder. The first top block is used to support the left half of the cylinder, and the second top block is used to support the right half of the cylinder.

[0009] The lifting assembly includes a first lifting drive and a second lifting drive. The top end of the first lifting drive is connected to one end of the connecting frame, and the top end of the second lifting drive is connected to the other end of the connecting frame. The first lifting drive and the second lifting drive are used to adjust the vertical distance between the connecting frame and the cylinder, as well as the tilt angle between the connecting frame and the horizontal direction.

[0010] Preferably, both the first lifting drive and the second lifting drive are motors or cylinders, and the cylinder lifting device further includes a controller for controlling the motor or the cylinder to lift the support assembly.

[0011] Preferably, both the first lifting drive and the second lifting drive are screw jacks, and the lifting assembly further includes a first coupling, which is connected between the first lifting drive and the second lifting drive, and is used to enable the first lifting drive and the second lifting drive to lift synchronously.

[0012] Preferably, the cylinder lifting device further includes an operating component, which includes a connecting rod and a gripper. One end of the connecting rod is connected to the lifting component, and the other end of the connecting rod is connected to the gripper.

[0013] Preferably, the operating assembly further includes a second coupling, which is drively connected between the connecting rod and the lifting assembly, and is used to adjust the axial direction of the connecting rod.

[0014] Preferably, the second coupling is a universal coupling.

[0015] Preferably, both the first top block and the second top block are made of wood.

[0016] Preferably, the first top block and the second top block have abutting arc surfaces, which are used to fit against the outer peripheral surface of the cylinder.

[0017] The beneficial effects of this utility model are as follows: By using this cylinder lifting device, when the cylinder stops rotating, the support component can be placed against the cylinder from bottom to top to provide stable support for the cylinder, thereby reducing the concentrated load between the cylinder and the support roller, ensuring that the roundness of the cylinder and the support roller is not damaged, thus avoiding periodic jumping of the cylinder during normal operation, ensuring the stability and safety of equipment operation, and also reducing the maintenance and replacement of the cylinder and the support roller, which can reduce the use cost and maintenance cost of cylinder equipment.

[0018] Another objective of this invention is to provide a cylindrical device with high operational stability.

[0019] To achieve this objective, the present invention adopts the following technical solution:

[0020] Cylindrical equipment, including:

[0021] frame;

[0022] A cylindrical body, which is rotatably mounted on the frame;

[0023] The support roller is rotatably mounted on the frame and can abut against the outer circumferential surface of the cylinder from bottom to top to drive the cylinder to rotate;

[0024] A support assembly includes a connecting frame arranged in a horizontal direction, and a first top block and a second top block spaced apart on the connecting frame.

[0027] The beneficial effects of this utility model are as follows: When the cylinder stops rotating, the support component abuts against the cylinder from bottom to top, providing stable support for the cylinder. This reduces the concentrated load between the cylinder and the support roller, ensuring that the roundness of the cylinder and the support roller is not damaged. This prevents the cylinder from periodically jumping during normal operation, ensuring the stability and safety of the equipment operation. It also reduces the maintenance and replacement of the cylinder and the support roller, thereby reducing the use and maintenance costs of the cylinder equipment. Attached Figure Description

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0031] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," "fixed," and "abutting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0033] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0034] The following is based on the appendix Figure 1 This invention introduces the cylinder lifting device and cylinder-type equipment provided by this utility model.

[0035] like Figure 1As shown, in this embodiment, the cylinder lifting device mainly includes a support assembly and a lifting assembly. The support assembly includes a horizontally arranged frame 7, and a first top block 6 and a second top block 8 spaced apart on the frame 7. The first top block 6 and the second top block 8 jointly support the outer circumferential surface of the cylinder, thereby reducing the pressure between the cylinder and the support roller, avoiding plastic deformation caused by concentrated loads, and ensuring that both the support roller and the cylinder (mainly the rolling ring part of the cylinder) have optimal roundness. The frame 7 ensures a relatively fixed positional relationship between the first top block 6 and the second top block 8, thereby improving the stability during support. Along the longitudinal section direction of the cylinder, the first top block 6 supports the left half of the cylinder, and the second top block 8 supports the right half of the cylinder; both provide joint support. Compared to support only by the first top block 6 or the second top block 8, joint support avoids large concentrated loads between the outer circumferential surface of the cylinder and the first top block 6 or the second top block 8, and also helps to prevent cylinder deformation. It should be noted that the first top block 6 and the second top block 8 can abut against the rolling ring part of the cylinder or other parts of the cylinder with sufficient structural strength, as long as they can achieve the effect of abutment and support.

[0036] The lifting assembly includes a first lifting drive 4 and a second lifting drive 9. The top end of the first lifting drive 4 is connected to one end of the connecting frame 7, and the top end of the second lifting drive 9 is connected to the other end of the connecting frame 7. The first lifting drive 4 can lift one end of the connecting frame 7, and the second lifting drive 9 can lift the other end of the connecting frame 7, so that the first lifting drive 4 and the second lifting drive 9 can adjust both the vertical distance between the connecting frame 7 and the cylinder and the tilt angle between the connecting frame 7 and the horizontal direction.

[0037] For example, when the cylinder is operating normally, the support assembly is lowered by the lifting component, creating a gap between the support assembly and the cylinder to avoid negatively impacting the cylinder's normal rotation. When the cylinder stops rotating, the support assembly is raised by the lifting component, allowing the first top block 6 and the second top block 8 to jointly support the cylinder, thus reducing the load between the support roller and the cylinder. Furthermore, to prevent uneven force distribution between the first top block 6 and the second top block 8, the tilt angle between the connecting frame 7 and the horizontal direction can be adjusted by controlling the first lifting drive component 4 and the second lifting drive component 9 respectively, ensuring that the first top block 6 and the second top block 8 support the cylinder with the same force, further reducing the negative impact on the cylinder's roundness.

[0038] This device allows the support components to abut against the cylinder from bottom to top when the cylinder stops rotating, providing stable support and reducing concentrated loads between the cylinder and the support rollers. This ensures that the roundness of the cylinder and the support rollers is not compromised, thus preventing periodic jumping of the cylinder during normal operation and ensuring the stability and safety of the equipment. It also reduces the need for maintenance and replacement of the cylinder and support rollers, thereby lowering the operating and maintenance costs of cylinder-type equipment.

[0039] Optionally, in some embodiments, both the first lifting drive component 4 and the second lifting drive component 9 are motors or cylinders, and the cylinder lifting device also includes a controller for controlling the motor or cylinder to lift the support assembly. The motor or cylinder facilitates support of the cylinder, and the controller enables automated control, allowing the support assembly to be automatically raised when the cylinder stops rotating and automatically lowered before the cylinder rotates, thereby reducing the workload of operators.

[0040] In this embodiment, as Figure 1 As shown, both the first lifting drive component 4 and the second lifting drive component 9 employ screw jacks. A screw jack includes components such as a worm gear, housing, bearings, and lead screw. It can drive the lifting assembly to rise and fall manually, significantly reducing the structural cost of the device and facilitating its installation in existing cylindrical equipment, thus enabling the retrofitting of old equipment. Furthermore, the lifting assembly also includes a first coupling 5, which is drivingly connected between the first lifting drive component 4 and the second lifting drive component 9. The first coupling 5 is used to synchronize the lifting of the first lifting drive component 4 and the second lifting drive component 9.

[0041] During installation, the tilt angle between the connecting frame 7 and the horizontal direction is first adjusted by rotating the first lifting drive component 4 and the second lifting drive component 9 respectively, so that the first top block 6 and the second top block 8 can be balanced by force. Then, the first coupling 5 is connected between the two screw jacks, so that when the operator operates one screw jack, the other can be raised and lowered synchronously, thereby further reducing the operator's workload.

[0042] Optionally, in this embodiment, the cylinder lifting device further includes an operating component, which includes a connecting rod 2 and a grip. One end of the connecting rod 2 is connected to the lifting component, and the other end of the connecting rod 2 is connected to the grip. The grip allows the operator to easily hold and rotate the cylinder, while the connecting rod 2 allows the operator to control the lifting component from a position away from it, thereby keeping the operator away from high-temperature or dangerous components such as the cylinder and improving the personal protection of the operator.

[0043] Preferably, the operating assembly further includes a second coupling 3, which is drively connected between the connecting rod 2 and the lifting assembly. The second coupling 3 can adjust the axial direction of the connecting rod 2, thereby further enabling the operator to operate the grip in a safe position. Exemplarily, in this embodiment, the second coupling 3 is a universal coupling.

[0044] Optionally, in this embodiment, both the first top block 6 and the second top block 8 are made of wood, preferably hardwood such as oak or birch. Wood can withstand the high temperatures of the cylinder due to heating, and wood itself has low hardness and a certain surface deformation capacity, which can increase the contact area through surface deformation when in contact with the cylinder, thus avoiding damage to the cylinder.

[0045] Preferably, the first top block 6 and the second top block 8 have abutting arc surfaces, which can fit snugly against the outer circumferential surface of the cylinder, thereby further increasing the contact area and reducing the negative impact of concentrated loads on the cylinder.

[0046] This utility model also provides a cylindrical device, which includes a frame, a cylindrical body, rollers, and the aforementioned support and lifting components. The frame is fixedly mounted, and both the cylindrical body and rollers are rotatably mounted on the frame. The rollers abut against the outer circumferential surface of the cylindrical body from bottom to top to drive the cylindrical body to rotate.

[0047] The support assembly includes a horizontally arranged frame 7 and a first top block 6 and a second top block 8 spaced apart on the frame 7. The first top block 6 and the second top block 8 jointly support the outer circumference of the cylinder, thereby reducing the pressure between the cylinder and the support roller, preventing plastic deformation caused by concentrated loads, and ensuring optimal roundness for both the support roller and the cylinder (mainly the rolling ring portion of the cylinder). The frame 7 ensures a relatively fixed positional relationship between the first top block 6 and the second top block 8, thus improving stability during support. Along the longitudinal section of the cylinder, the first top block 6 supports the left half of the cylinder, and the second top block 8 supports the right half, with both providing joint support. Compared to support by only the first top block 6 or the second top block 8, joint support avoids large concentrated loads between the outer circumference of the cylinder and the first top block 6 or the second top block 8, and also helps prevent deformation of the cylinder.

[0048] The lifting assembly includes a first lifting drive 4 and a second lifting drive 9. The top end of the first lifting drive 4 is connected to one end of the connecting frame 7, and the top end of the second lifting drive 9 is connected to the other end of the connecting frame 7. The first lifting drive 4 can lift one end of the connecting frame 7, and the second lifting drive 9 can lift the other end of the connecting frame 7, so that the first lifting drive 4 and the second lifting drive 9 can adjust both the vertical distance between the connecting frame 7 and the cylinder and the tilt angle between the connecting frame 7 and the horizontal direction.

[0049] This cylindrical equipment can provide stable support to the cylinder by having the support components abut against it from bottom to top when the cylinder stops rotating. This reduces the concentrated load between the cylinder and the support rollers, ensuring that the roundness of the cylinder and the support rollers is not damaged. This prevents the cylinder from experiencing periodic jumping during normal operation, ensuring the stability and safety of the equipment. It also reduces the maintenance and replacement of the cylinder and the support rollers, thereby lowering the operating and maintenance costs of the cylindrical equipment.

[0050] Preferably, the device further includes an operating assembly, which includes a connecting rod 2, a seated bearing 10, and a grip. One end of the connecting rod 2 is connected to the lifting assembly, and the other end of the connecting rod 2 is connected to the grip. The seated bearing 10 is fixedly mounted on the frame, and the connecting rod 2 is rotatably mounted through the seated bearing 10. The seated bearing 10 allows the connecting rod 2 to rotate stably around its own axis, thereby reducing the operator's workload.
