Description

Technical Field

[0001] The utility model relates to the technical field of tobacco machinery, in particular to a maintenance tool, a glue pump and a filter rod forming machine. Background Art

[0002] In the production and packaging of products in various industries, glue is usually needed for bonding, packaging and other processes. For example, in the tobacco field, the glue pump is a key component of the cigarette filter rod forming machine. The glue pump is used to transport and supply glue to ensure that during the filter rod forming process, the forming paper overlap can be evenly coated with glue to form a strong bond.

[0003] However, during the long-term operation of the equipment, impurities such as lumps and debris may be mixed into the glue. These impurities may come from the glue itself, or they may be caused by improper protection during the storage of the glue, incomplete cleaning of the glue supply pipeline, and intrusion of external environmental pollutants. Once these impurities enter the glue pump, they often cause the glue pump to rotate inflexibly and vibrate, especially in the gear meshing area, which is prone to gear jumping, slipping, and jamming, resulting in unstable output of the glue pump, and the inability to accurately control the glue supply pressure and flow, which seriously affects production efficiency. If this phenomenon occurs for a long time, it will accelerate the wear of the glue pump gears and other transmission parts, shortening the service life of the glue pump.

[0004] It should be noted that the information disclosed in the background technology section of the present invention is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or suggestion in any form that the information constitutes prior art already known to those skilled in the art.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] In the description of the present invention, it should be understood that the terms "center", "lateral", "longitudinal", "front", "rear", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the scope of protection of the present invention.

[0032] The glue pump is usually equipped with a mechanism such as a gear or a piston driven by a drive shaft, which is used to transport adhesive materials such as glue to the nozzle device of the glue pump for output. Therefore, the operation of the drive shaft of the glue pump has a key impact on the working stability of the glue pump.

[0033] refer to Figure 1 As shown, in some embodiments of the maintenance tool 1 provided by the utility model, the maintenance tool 1 includes a limiting portion 11 and a holding portion 12, the limiting portion 11 is used to cooperate with the driving shaft 2 of the glue pump, the holding portion 12 is connected to the limiting portion 11, and the holding portion 12 is configured to receive external torque to drive the limiting portion 11 to rotate, thereby driving the driving shaft 2 to rotate.

[0034] By providing the limiting portion 11, the maintenance tool 1 can be stably matched with the drive shaft 2, so that the torque can be transmitted to the drive shaft 2 through the limiting portion 11. When the drive shaft 2 rotates unsmoothly or jams, the limiting portion 11 can be driven to rotate by rotating the gripping portion 12, and then the limiting portion drives the drive shaft 2 to rotate, so that the drive shaft 2 quickly returns to a normal working state, thereby specifically solving the problem of poor operation of the glue pump.

[0035] The gripping portion 12 can be designed to be a structure that is convenient for operators to hold and apply force, such as setting an anti-slip thread on the outside of the gripping portion, or the gripping portion 12 can be set to a structure that is convenient for machine clamping, such as setting a slot structure corresponding to the robot claw on the gripping portion 12. Therefore, when the drive shaft 2 cannot rotate smoothly, the maintenance tool 1 can be rotated by manpower or machine to drive the drive shaft 2 to return to a normal working state, so as to quickly maintain the glue pump.

[0036] In practical applications, the maintenance tool 1 of the present invention is not limited to the maintenance of glue pumps, but is also applicable to the maintenance of other devices with similar rotating shaft structures.

[0037] In some embodiments, the maintenance tool 1 further includes a power assisting portion 13 , which is detachably mounted on an end of the gripping portion 12 away from the limiting portion 11 to form a force applying structure for applying torque to the gripping portion 12 .

[0038] The power-assisting part 13 can be quickly assembled to or removed from the gripping part 12 as needed. For example, when the jamming of the driving shaft 2 of the glue pump is serious, a larger torque is required to turn the driving shaft 2. At this time, the power-assisting part 13 can be installed to assist in applying force. Therefore, when facing a large resistance, the driving shaft 2 can be easily turned with the help of the power-assisting part, which effectively reduces the labor intensity.

[0039] The structure of the assisting portion 13 can be adaptively designed according to different usage requirements.

[0040] For example, the assisting portion 13 may be configured as a rod-shaped or plate-shaped structure that is larger than the gripping portion 12 , so as to increase the torque and save effort by extending the lever arm.

[0041] Specifically, refer to Figure 1As shown, in some embodiments, the assisting portion 13 includes a screw rod, and an end of the gripping portion 12 away from the limiting portion 11 is provided with a mounting hole 121 , and the screw rod is detachably inserted into the mounting hole 121 .

[0042] Alternatively, in some other embodiments, the power assisting portion 13 can be set as a driving motor, and the output shaft of the driving motor can be connected to the holding portion 12. The rotation of the output shaft can directly drive the holding portion 12 to rotate, without manual operation, thereby facilitating automation.

[0043] In other solutions, hydraulic structure, magnetic drive, etc. are also optional forms of the power assisting part 13.

[0044] refer to Figure 3 As shown, in some embodiments, the limiting portion 11 includes a first working surface 111 and a second working surface 112, and the first working surface 111 and the second working surface 112 are configured to respectively abut against both sides of the limiting groove of the drive shaft 2 so that the limiting portion 11 can be matched with the drive shaft 2. The first working surface 111 and the second working surface 112 can be designed in the form of a plane, a curved surface, etc., as long as they can achieve positioning and stable matching with both sides of the limiting groove.

[0045] In some embodiments, the limiting portion 11 further includes a third working surface 113 connected between the first working surface 111 and the second working surface 112 , and the third working surface 113 is configured to abut against the bottom of the limiting groove of the drive shaft 2 to enable the limiting portion 11 to cooperate with the drive shaft 2 .

[0046] The multiple contact design of the first working surface 111, the second working surface 112 and the third working surface 113 can ensure the all-round cooperation between the limiting portion 11 and the limiting groove of the drive shaft 2, which helps to improve the cooperation stability and prevent the maintenance tool 1 from slipping or shifting during the rotation of the drive shaft 2. Especially when the rotational torque is large, sufficiently high cooperation stability can effectively avoid accidental damage to components or operators.

[0047] In such Figure 1 In the illustrated embodiment, the limiting portion 11 is configured as a rectangular block structure, the first working surface 111 and the second working surface 112 are configured as two opposite surfaces on the rectangular block, and the third working surface 113 is configured as the bottom surface of the rectangular block.

[0048] Among them, the length of the rectangular block (the length of the first working surface 111), the width of the rectangular block (the width of the third working surface 113) and the thickness of the rectangular block (i.e., the width of the first working surface 111 and the second working surface 112) can be designed according to the specific specifications of the limit groove of the drive shaft 2.

[0049] The specific structure of the limiting portion 11 can be set according to the specific structure of the limiting groove of the driving shaft 2, for example, it can also be set to a cross shape, a T shape, etc.

[0050] In some embodiments, the limiting portion 11 and the holding portion 12 are vertically connected to form a T-shaped structure.

[0051] Based on the above maintenance tool 1, the utility model also proposes a glue pump, referring to Figure 5 As shown, the glue pump includes a box body 3, a drive shaft 2 and the above-mentioned maintenance tool 1, the box body 3 is used to store glue, the drive shaft 2 is rotatably arranged in the box body 3, and the maintenance tool 1 is configured to selectively cooperate with the drive shaft 2 to drive the drive shaft 2 to rotate relative to the box body 3.

[0052] In some embodiments, the glue pump further includes a gear set, which is sleeved on the drive shaft body 21 , and the drive shaft body 21 extends into the box body 3 . When the drive shaft body 21 rotates, it drives the gear set to rotate to pump out the glue in the box body 3 .

[0053] When the drive shaft 2 needs to be maintained, such as checking before starting, adjusting the matching of the gears installed on the drive shaft 2, and assisting the drive shaft 2 that is not running smoothly to rotate, the maintenance tool 1 can be quickly matched with the drive shaft.

[0054] refer to Figure 5 As shown, in some embodiments, the drive shaft 2 includes a drive shaft body 21 and a shaft end cover 22 installed at the end of the drive shaft body 21 , and the shaft end cover 22 is provided with a limiting groove for cooperating with the maintenance tool 1 .

[0055] The drive shaft body 21 and the shaft end cover 22 are arranged to be detachably connected to facilitate installation and maintenance.

[0056] The limiting groove enables the driving shaft 2 to be conveniently and stably docked with the maintenance tool 1, so that the maintenance tool 1 can be used to perform maintenance work such as inspection, adjustment or replacement of the glue pump.

[0057] Figure 2 The schematic diagram of the structure of the shaft end cover 22 in some embodiments is shown. The shaft end cover 22 includes a first matching portion 221 and a second matching portion 222 that are arranged opposite to each other, and a limiting groove is formed between the first matching portion 221 and the second matching portion 222.

[0058] refer to Figure 3 and Figure 4 As shown, the limiting portion 11 of the maintenance tool 1 cooperates with the limiting groove on the shaft end cover 22, the first working surface 111 abuts against the first matching portion 221, the second working surface 112 abuts against the second matching portion 222, and the third working surface 113 abuts against the bottom of the limiting groove, thereby achieving stable engagement between the limiting portion 11 and the limiting groove.

[0060] Specifically, if the driving shaft 2 of the glue pump and the gear set do not rotate flexibly, which affects the delivery and supply of the glue, the filter rod will not be formed, resulting in a large amount of product consumption.

[0061] The utility model provides a maintenance tool 1 in the glue pump, so that the glue pump can be maintained in time when a failure occurs, thereby ensuring the stability of the glue conveying, achieving good adhesion of the overlap of the forming paper, and ensuring the quality of the final filter rod.
