Description

Technical Field

[0001] This utility model relates to the technical field of cigarette production equipment, and in particular to a lifting mechanism and feeding device for a feeding device. Background Technology

[0002] To meet diverse consumer needs, existing cigarette products typically incorporate granular materials or powders with special flavorings during the cigarette manufacturing process. These enhance the aroma during smoking, thereby improving the consumer's smoking experience.

[0003] In the prior art, material adding equipment is usually used to automatically add granular materials or powders, and the material adding equipment is equipped with a feeding device for automatically adding powder or granular materials into the filter rod.

[0004] As disclosed in publication number CN115581314A, the existing feeding device typically includes a base, an annular guide rail assembly, and a feeding unit. The feeding unit can move cyclically along the annular guide rail assembly. During the movement, the feeding unit achieves material blocking and dropping through the relative lifting of internal components, thereby conveying the material into the filter rod.

[0005] The filter rod conveyor line is located at the bottom of the feeding device. During material addition, the feeding device needs to be placed as close as possible to the filter rod conveyor line to ensure that the feeding unit in the feeding device can accurately feed the material into the filter rods on the conveyor line. When maintenance is required on the feeding device or the filter rod conveyor line, the feeding device needs to be moved sufficiently away from the filter rod conveyor line to facilitate maintenance by personnel.

[0006] However, in the existing technology, the adjustment of the positional relationship between the feeding device and the filter rod conveyor line is done manually by the staff. This manual adjustment is prone to positional errors, which result in errors in the positional relationship between the feeding device and the filter rod conveyor line during reset. This affects the accuracy of the subsequent feeding device's material delivery to the filter rods, and after maintenance, the staff needs to repeatedly adjust the positional relationship between the feeding device and the filter rod conveyor line, which greatly affects production efficiency.

[0007] Therefore, how to provide a mechanism to drive the feeding device to move, so as to better avoid relative displacement errors between the feeding device and the filter rod conveyor line during maintenance, and at the same time better ensure safety, is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0008] To address the aforementioned problems, this utility model provides a lifting mechanism for a feeding device. This mechanism is connected to the feeding device and can drive it to rise and fall. When the feeding device or filter rod conveyor line needs maintenance, it can lift the feeding device away from the filter rod conveyor line. After maintenance, it can lower the feeding device to approach the filter rod conveyor line. By directly driving the feeding device to rise and fall through a mechanical structure, the position of the feeding device can be adjusted. Positional errors are less likely to occur between the feeding device and the filter rod conveyor line, thus eliminating the need for repeated adjustments to their position and improving production efficiency.

[0009] A lifting mechanism for a feeding device includes a frame and a self-locking lifting assembly;

[0010] The self-locking lifting assembly is installed on the frame, and the self-locking lifting assembly includes a drive unit and a lead screw lifting unit;

[0011] The lead screw lifting unit includes a driving part and a lifting part connected to the driving part, the lifting part being used to connect to the feeding device;

[0012] The drive unit is connected to the drive section and is used to drive the drive section to operate, thereby driving the lifting section to rise and fall, so that the unloading device stops at a working position close to the filter rod conveyor line, or stops at a maintenance position far away from the filter rod conveyor line.

[0013] Preferably, the screw lifting unit is a trapezoidal screw jack.

[0014] Preferably, the drive unit uses a servo motor as its power source.

[0015] Preferably, the drive unit uses a brake motor as its power source.

[0016] Preferably, the output shaft of the drive unit is connected to the input shaft of the drive section via a coupling.

[0017] Preferably, the top of the lifting part is provided with a connector for connecting to the unloading device.

[0018] Preferably, the frame includes a bottom wall and side walls connected to the bottom wall, the side walls and the bottom wall together forming an accommodating space;

[0019] The drive unit is mounted on the bottom wall and is at least partially located in the receiving space;

[0020] The drive unit is mounted on the side wall, and its output shaft extends into the receiving space.

[0021] A feeding device includes a lifting mechanism, a feeding device, and a controller as described in any one of the above-mentioned feeding devices;

[0022] The feeding device includes a base, an annular guide rail assembly, a feeding unit, and a drive mechanism. The annular guide rail assembly is mounted on the base, the feeding unit is mounted on the annular guide rail assembly, and the drive mechanism is mounted on the base. The drive mechanism is used to drive the feeding unit to move along the annular guide rail assembly, and the feeding unit cooperates with the annular guide rail assembly to feed materials sequentially at the feeding positions during the movement.

[0023] The lifting section is connected to the base or the annular guide rail assembly;

[0024] The drive unit is communicatively connected to the controller and is used to drive the lifting part to rise and fall according to the drive signal output by the controller, so that the unloading device stops at the working position close to the filter rod conveyor line or at the maintenance position far away from the filter rod conveyor line.

[0025] Preferably, it further includes a vertical guide component, which includes a guide rail arranged vertically and a slider slidably disposed on the guide rail, the slider being connected to the lifting part.

[0026] Compared with the prior art, the lifting mechanism of the feeding device provided by this utility model includes a frame and a self-locking lifting assembly. The self-locking lifting assembly is installed on the frame and includes a drive unit and a screw lifting unit. The screw lifting unit includes a drive part and a lifting part connected to the drive part, and the lifting part is used to connect to the feeding device. The drive unit is connected to the drive part and drives the drive part to move, thereby driving the lifting part to move up and down, so that the feeding device stops at a working position close to the filter rod conveyor line, or stops at a maintenance position far away from the filter rod conveyor line. The lifting mechanism of the feeding device can drive the drive part to move through the drive unit, thereby driving the lifting part to move up and down, thereby driving the feeding device to move up and down, so that the feeding device stops at the working position or maintenance position. When the feeding device is under maintenance and reset, it is not easily affected by human factors, and can better avoid positional errors between the feeding device and the filter rod conveyor line. Therefore, it is not necessary to repeatedly adjust the positional relationship between the feeding device and the filter rod conveyor line, thereby improving production efficiency. Furthermore, the self-locking lifting mechanism locks the position of the unloading device after adjustment, ensuring its stability in case of emergencies (such as power or gas outages), thus enhancing safety. Simultaneously, the screw-driven lifting mechanism allows for controllable stroke, enabling more precise movement to the desired position and ensuring accurate resetting of the unloading device. This, in turn, improves the accuracy of subsequent material placement, further enhancing production efficiency. Attached Figure Description

[0036] This utility model provides a lifting mechanism for a feeding device, comprising a frame and a self-locking lifting assembly. The self-locking lifting assembly is mounted on the frame and includes a drive unit and a lead screw lifting unit. The lead screw lifting unit includes a drive portion and a lifting portion connected to the drive portion, the lifting portion being connected to the feeding device. The drive unit is connected to the drive portion and drives the drive portion to move, thereby raising and lowering the lifting portion, so that the feeding device stops at a working position close to the filter rod conveyor line, or stops at a maintenance position far from the filter rod conveyor line. The lifting mechanism of the feeding device, through the drive unit, can drive the drive portion to move, thereby raising and lowering the lifting portion, thus raising and lowering the feeding device, stopping it at the working or maintenance position. During maintenance and resetting of the feeding device, it is less susceptible to human error and can better avoid positional errors between the feeding device and the filter rod conveyor line, thus eliminating the need for repeated adjustments to the positional relationship between the feeding device and the filter rod conveyor line, thereby improving production efficiency. Furthermore, the self-locking lifting mechanism locks the position of the unloading device after adjustment, ensuring its stability in case of emergencies (such as power or gas outages), thus enhancing safety. Simultaneously, the screw-driven lifting mechanism allows for controllable stroke, enabling more precise movement to the desired position and ensuring accurate resetting of the unloading device. This, in turn, improves the accuracy of subsequent material placement, further enhancing production efficiency.

[0037] Please refer to the following: Figures 1 to 3 This embodiment provides a lifting mechanism 100 for a feeding device, which drives the feeding device to lift and lower, thereby facilitating the maintenance and resetting of the feeding device.

[0038] The lifting mechanism 100 of the unloading device includes a frame 10 and a self-locking lifting assembly 20. The self-locking lifting assembly 20 is mounted on the frame 10 and includes a drive unit 21 and a lead screw lifting unit 22. The lead screw lifting unit 22 includes a drive part 221 and a lifting part 222 connected to the drive part 221. The lifting part 222 is used to connect to the unloading device. The drive unit 21 is connected to the drive part 221 and drives the drive part 221 to move, thereby driving the lifting part 222 to rise and fall, so that the unloading device stops at a working position close to the filter rod conveyor line, or stops at a maintenance position away from the filter rod conveyor line. That is, after the lifting part 222 is connected to the unloading device, it can be driven by the drive unit 21 to drive the unloading device to rise and fall in the vertical direction. When maintenance is required on the feeding device or filter rod conveyor line, the self-locking lifting assembly 20 can be used to raise the feeding device, so that the feeding device can be stopped in the maintenance position, which makes it convenient for staff to maintain the feeding device or filter rod conveyor line. After maintenance is completed, the self-locking lifting assembly 20 can directly lower the feeding device, so that the feeding device can be stopped in the working position.

[0039] The self-locking lifting assembly 20 refers to a lifting assembly with a self-locking structure. This structure is installed in the drive unit 21 or the lead screw lifting unit 22, allowing power to be transmitted only along the directions of the drive unit 21, the drive section 221, and the lifting section 222. Reverse force cannot cause the self-locking lifting assembly 20 to operate. Therefore, once the position is adjusted to the correct position, the self-locking structure fixes the position, preventing changes due to unforeseen circumstances.

[0040] It should be noted that the lifting part 222 can be directly or indirectly connected to the unloading device. For example, when there is installation space below the unloading device, the self-locking lifting assembly 20 can be directly installed on the lower side of the unloading device, so that the lifting part 222 can be directly connected to the bottom of the unloading device through the mounting connector. When there is insufficient installation space below the unloading device, the self-locking lifting assembly 20 can be installed on the side of the unloading device, so that the lifting part 222 can be connected to the transition connecting plate through the mounting connector, and the transition connecting plate is then connected to the top or side of the unloading device, thereby achieving an indirect connection between the lifting part 222 and the unloading device.

[0041] Understandably, in the existing technology, when the feeding device or filter rod conveyor line needs maintenance, the position of the feeding device is adjusted manually by the staff. Due to human factors, positional errors are very easy to occur. When resetting, the feeding device cannot move accurately to its original position, which affects the accuracy of the subsequent feeding device feeding material to the filter rod. This also requires the staff to repeatedly adjust the positional relationship between the feeding device and the filter rod conveyor line, which greatly affects production efficiency.

[0042] This embodiment provides a lifting mechanism 100 for the unloading device. The self-locking lifting assembly 20 can move the unloading device vertically. When maintenance is required, the unloading device only needs to be raised. After maintenance, the self-locking lifting assembly 20 can directly drive the unloading device to descend and reset. By using a mechanical structure to move the unloading device only in the vertical direction, positional errors can be better avoided. At the same time, human interference with position adjustment is minimized. Therefore, when resetting, the position of the unloading device no longer needs to be repeatedly adjusted, which can improve production efficiency. Furthermore, the self-locking lifting assembly 20 uses the lead screw lifting unit 22 to drive the unloading device to rise and fall. Compared with using cylinders or other components as the lifting drive, the lead screw structure makes the lifting stroke more controllable and allows for more precise control of the lifting position, thereby improving positional accuracy and ensuring the accuracy of the unloading device's lifting position. On the other hand, in case of unexpected situations (such as a sudden power or gas outage), the self-locking lifting assembly 20 can maintain the position of the unloading device, preventing it from falling accidentally and thus improving safety.

[0043] Preferably, in one embodiment, the screw jack unit 22 is a trapezoidal screw jack. Using a trapezoidal screw jack allows for quick and convenient adjustment of the lifting stroke, and the trapezoidal screw has a self-locking function, maintaining its position even in the event of a power or gas outage. In other words, in this embodiment, the transmission structure of the screw jack unit 22 has a self-locking capability, thus ensuring that the unloading device will not accidentally fall off in the event of an accident through the cooperation between the worm gear and the trapezoidal screw in the screw jack unit 22. Specifically, in one embodiment, the screw in the screw jack unit 22 is the lifting part 222, meaning that during operation, the screw in the screw jack unit 22 performs lifting and lowering movements.

[0044] Specifically, in one embodiment, the drive unit 21 uses a motor as a power source, and the drive unit 21 may also be equipped with power transmission components such as a reduction gearbox and a steering gearbox as needed.

[0045] Preferably, in one embodiment, the drive unit 21 uses a servo motor as the power source, thereby giving the self-locking lifting assembly 20 better accuracy and stability.

[0046] Preferably, in one embodiment, the drive unit 21 uses a brake motor as a power source, so that when the drive unit 21 is de-energized, the motor shaft can be locked by the braking structure to prevent the unloading device from falling due to power failure.

[0047] Preferably, in one embodiment, the output shaft of the drive unit 21 and the input shaft of the drive part 221 are connected by a coupling 30, thereby better ensuring the reliability of power transmission between the drive unit 21 and the drive part 221.

[0048] Preferably, in one embodiment, the top of the lifting part 222 is provided with a connector 2221, which is used to connect to the unloading device. The connector 2221 can be directly or indirectly connected to the unloading device. For example, the connector 2221 can be directly connected to the unloading device via an installation connector; or, the connector 2221 can be connected to a transition connecting plate via an installation connector, and the transition connecting plate is then connected to the unloading device, thereby achieving an indirect connection between the connector 2221 and the unloading device.

[0049] Preferably, in one embodiment, the frame 10 includes a bottom wall 11 and side walls 12 connected to the bottom wall 11, the side walls 12 and the bottom wall 11 together forming a receiving space 13. The drive part 221 is mounted on the bottom wall 11 and is at least partially located in the receiving space 13. The drive unit 21 is mounted on the side wall 12, and its output shaft extends into the receiving space 13. Specifically, in one embodiment, four side walls 12 are provided, the four side walls 12 and the bottom wall 11 together forming the receiving space 13, and the drive unit 21 is mounted on one of the side walls 12.

[0050] Meanwhile, in one embodiment, a feeding device is also provided, which includes a lifting mechanism 100 of the feeding device, a feeding device, and a controller. The feeding device includes a base, an annular guide rail assembly, a feeding unit, and a drive mechanism. The annular guide rail assembly is disposed on the base, the feeding unit is disposed on the annular guide rail assembly, and the drive mechanism is disposed on the base. The drive mechanism is used to drive the feeding unit to move along the annular guide rail assembly, and the feeding unit cooperates with the annular guide rail assembly to feed materials sequentially at the feeding position during the movement. The lifting part 222 is connected to the base or the annular guide rail assembly, and the drive unit 21 is communicatively connected to the controller to drive the lifting part 222 to rise and fall according to the drive signal output by the controller, so that the feeding device stops at a working position close to the filter rod conveyor line or at a maintenance position far away from the filter rod conveyor line. That is, the self-locking lifting assembly 20 is used to operate according to the drive signal received from the controller, thereby driving the feeding device to rise and fall in the vertical direction and change the position of the feeding device. The controller can be any controller such as a PLC, which is well known to those skilled in the art and will not be described in detail here.

[0051] Preferably, in one embodiment, the unloading device further includes a vertical guide component, which includes a vertically arranged guide rail and a slider slidably disposed on the guide rail. The slider is connected to the lifting part. Specifically, the slider may be disposed on a mounting connector (or transition connecting plate) connected to the lifting part 222. By providing the vertical guide component, the direction of movement can be better guided during the lifting process, ensuring that the unloading device only moves vertically.

[0052] The above description is merely an embodiment of this utility model. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this utility model, but these improvements all fall within the protection scope of this utility model.
