[0002] In the cigarette packaging process, there are usually three width specifications of tipping paper corresponding to the production of various specifications of cigarettes. In order to align the tipping paper tube with the height center of the cigarette to be packaged, it is necessary to add three different thickness specifications of tipping paper tray washers under the tipping paper roll.

[0003] Traditional cork paper tray gaskets are usually set to one thickness specification corresponding to one independent gasket. During the brand change process, the paper tray rack needs to be adjusted according to the different widths of cork paper, and gaskets of different thickness specifications need to be replaced to make the center of the cork paper centered on the cigarette conveying path. Each brand change takes a lot of time here, and each machine needs to prepare multiple gaskets for brand changes. In addition, the brand changes frequently, the number of adjustments increases, the process is cumbersome and extremely inconvenient. Utility Model Content

[0004] The purpose of the utility model is to provide an adjustable pad block for a paper tray rack, so as to solve the problem that the replacement of the gasket of the traditional paper tray rack is time-consuming, cumbersome and inconvenient.

[0005] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0006] An adjustable pad for a paper tray rack comprises an annular base, an adjustment mechanism and a gasket, wherein the gasket is arranged on the adjustment mechanism, and the adjustment mechanism is sleeved on the annular base and is used to adjust the height of the gasket; when the adjustment mechanism is contracted to a minimum height, the gasket is retracted in the adjustment mechanism; when the adjustment mechanism is extended to a maximum height, the gasket protrudes out of the adjustment mechanism; the adjustment mechanism comprises a toothed disk sleeved on the annular base, the toothed disk is provided with a first adjustment ring protruding upward, the first adjustment ring is provided with an external thread, and the adjustment mechanism also comprises a second adjustment ring, the second adjustment ring is provided with an internal thread matching the first adjustment ring.

[0007] In the present technical solution, the height of the gasket is adjusted by the adjustment mechanism, thereby realizing the adjustment of the overall height of the adjustable pad of the paper tray rack, which is convenient for adapting to various width specifications of kraft paper tubes, and the adjustment process does not require the disassembly, assembly or change of any parts, which is convenient to use and has strong practicality. The adjustment mechanism of the present technical solution drives the first adjustment ring to rotate by rotating the toothed disk, and under the cooperation of the external thread of the first adjustment ring and the internal thread of the second adjustment ring, the second adjustment ring rises slowly, so that the gasket set on the adjustment mechanism gradually rises, realizing the flexible adjustment of the height of the adjustable pad of the paper tray rack, which is convenient for adapting to various specifications of kraft paper tubes, which is convenient to use and has strong practicality.

[0008] It is further defined that a bearing is also provided between the toothed disk and the annular base. Such a structural design, by providing a bearing between the toothed disk and the annular base, makes the rotation of the toothed disk smoother, reduces the resistance and friction loss generated during the rotation of the toothed disk, has a simple structure and is highly practical.

[0009] It is further defined that the annular base includes a seat ring with a convex cross section, the bearing sleeve is arranged on the seat ring, the annular base also includes a sleeve with a convex cross section, the seat ring and the sleeve are both arranged on the same annular disk, and the second adjustment ring, the sleeve and the washer are all provided with mutually matching limiting grooves and limiting protrusions. Such a structural design suspends the bearing in the air through the seat ring with a convex cross section, thereby avoiding direct contact with the annular base during the rotation of the bearing to generate friction loss. At the same time, through the limiting grooves and limiting protrusions on the second adjustment ring, the sleeve and the washer, when the second adjustment ring and the washer are raised under the drive of the first adjustment ring, friction between the threads of the second adjustment ring and the first adjustment ring is avoided, so that the second adjustment ring rotates synchronously with the first adjustment ring, ensuring that the kinetic energy conversion of the first adjustment ring can achieve the expected height adjustment effect. The structure is simple and has strong practicality.

[0010] It is further defined that at least two rack structures are provided on the gasket and the casing, and the second adjustment ring is provided with a gear that meshes with the rack structures on the gasket and the casing at the same time. Such a structural design enables the gasket to be synchronously raised with the second adjustment ring through the cooperation of the gear and the rack when the second adjustment ring is raised driven by the first adjustment ring. In this way, the raising of the second adjustment ring and the gasket can realize double-layer height adjustment under the same power source (i.e., the rotation of the toothed disk). At the same time, without the gasket being raised, the gasket can also be retracted into the casing together with the second adjustment block, thereby reducing the space occupied by the adjustable pad of the paper tray rack and adapting to various specifications of cork paper tubes.

[0011] It is further defined that the adjustable pad of the paper tray rack also includes a positioning mechanism, the positioning mechanism includes a positioning rod connected to the casing, and the positioning rod is provided with a positioning block; when the positioning rod is raised, the toothed disk is in an active state; when the positioning rod is lowered, the positioning block is clamped in the tooth groove of the toothed disk. Such a structural design, through the positioning rod and the positioning block, when the adjustable pad of the paper tray rack is at an ideal height, the rotation of the toothed disk can prevent the user from accidentally touching it, or the toothed disk rotates with the rotation of the cork paper tube during operation, resulting in unexpected changes in the height of the adjustable pad of the paper tray rack. The structure is simple and has strong practicality.

[0012] The utility model adopting the above technical solution has the following advantages:

[0013] 1. The utility model adjusts the height of the gasket through the adjustment mechanism, thereby realizing the adjustment of the overall height of the adjustable pad of the paper tray rack, which is convenient for adapting to various width specifications of kraft paper tubes, and the adjustment process does not require disassembly, assembly or change of any parts, which is easy to use and has strong practicality.

[0014] 2. The utility model suspends the bearing in the air by means of a seat ring with a convex cross-section, thereby avoiding friction loss caused by direct contact between the bearing and the annular base during rotation. At the same time, by means of the limiting grooves and limiting protrusions on the second adjusting ring, the sleeve and the washer, friction is avoided between the threads of the second adjusting ring and the first adjusting ring when the second adjusting ring and the washer are raised under the drive of the first adjusting ring, so that the second adjusting ring rotates synchronously with the first adjusting ring, ensuring that the kinetic energy conversion of the first adjusting ring can achieve the expected height adjustment effect. The structure is simple and has strong practicality.

[0015] 3. In the utility model, when the second adjusting ring rises driven by the first adjusting ring, the gasket rises synchronously with the second adjusting ring through the cooperation of the gear and the rack. In this way, the rising of the second adjusting ring and the gasket can achieve double-layer height adjustment under the same power source (i.e., the rotation of the toothed disk). At the same time, without the need to raise the gasket, the gasket can also be retracted into the shell together with the second adjusting block, thereby reducing the space occupied by the adjustable gasket of the paper tray rack and adapting to various specifications of cork paper tubes.

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that in the drawings or in the specification, similar or identical parts use the same figure numbers, and the implementation methods not shown or described in the drawings are forms known to ordinary technicians in the relevant technical field. In addition, the directional terms mentioned in the embodiments, such as "upper", "lower", "top", "bottom", "left", "right", "front", "back", etc., are only referenced to the directions of the drawings and are not used to limit the scope of protection of the present invention.

[0026] like Figures 1 to 4 As shown, the utility model is an adjustable pad block for a paper tray rack, comprising an annular base 1, an adjustment mechanism and a gasket 2, wherein the gasket 2 is arranged on the adjustment mechanism, and the adjustment mechanism is sleeved on the annular base 1 for adjusting the height of the gasket 2;

[0027] When the adjusting mechanism is retracted to a minimum height, the washer 2 is retracted in the adjusting mechanism;

[0028] When the adjusting mechanism is extended to the maximum height, the washer 2 protrudes out of the adjusting mechanism.

[0029] In this embodiment, the height of the gasket 2 is adjusted by the adjustment mechanism, thereby realizing the adjustment of the overall height of the adjustable pad of the paper tray rack, which is convenient for adapting to various width specifications of kraft paper tubes, and the adjustment process does not require disassembly, assembly or change of any parts, so it is easy to use and has strong practicality.

[0030] In some optional embodiments, the adjustment mechanism includes a toothed disk 3 sleeved on the annular base 1, and the toothed disk 3 is provided with a first adjustment ring 4 protruding upward, and the first adjustment ring 4 is provided with an external thread, and the adjustment mechanism also includes a second adjustment ring 5, and the second adjustment ring 5 is provided with an internal thread matching the first adjustment ring 4. Such a structural design drives the first adjustment ring 4 to rotate by rotating the toothed disk 3, and under the cooperation of the external thread of the first adjustment ring 4 and the internal thread of the second adjustment ring 5, the second adjustment ring 5 rises slowly, so that the gasket 2 set on the adjustment mechanism gradually rises, and the height of the adjustable pad of the paper tray rack is flexibly adjusted, which is convenient for adapting to various specifications of kraft paper tubes, and is easy to use and has strong practicality. In some optional technical solutions, the first adjustment ring 4 can be provided with an internal thread, and the second adjustment ring 5 can be provided with an external thread. The setting method of the thread is not specifically limited here, and the thread cooperation between the first adjustment ring 4 and the second adjustment ring 5 can be achieved.

[0031] In some optional embodiments, a bearing 6 is further provided between the toothed disk 3 and the annular base 1. Such a structural design, by providing a bearing 6 between the toothed disk 3 and the annular base 1, makes the rotation of the toothed disk 3 smoother, reduces the resistance and friction loss generated during the rotation of the toothed disk 3, has a simple structure and strong practicality.

[0032] In some optional embodiments, the annular base 1 includes a seat ring 101 with a convex cross section, the bearing 6 is sleeved on the seat ring 101, the annular base 1 also includes a housing 102 with a convex cross section, the seat ring 101 and the housing 102 are both arranged on the same annular disk 103, and the second adjustment ring 5, the housing 102 and the washer 2 are all provided with mutually matching limiting grooves and limiting protrusions. Such a structural design suspends the bearing 6 in the air through the seat ring 101 with a convex cross section, thereby avoiding direct contact between the bearing 6 and the annular base 1 during the rotation process to generate friction loss. At the same time, through the limiting grooves and limiting protrusions on the second adjustment ring 5, the housing 102 and the washer 2, when the second adjustment ring 5 and the washer 2 are lifted under the drive of the first adjustment ring 4, the threads between the second adjustment ring 5 and the first adjustment ring 4 are prevented from generating friction, so that the second adjustment ring 5 rotates synchronously with the first adjustment ring 4, ensuring that the kinetic energy conversion of the first adjustment ring 4 can achieve the expected height adjustment effect, and the structure is simple and has strong practicality.

[0033] In some optional embodiments, at least two rack structures 7 are provided on the gasket 2 and the casing 102, and a gear 8 meshing with the rack structures 7 on the gasket 2 and the casing 102 is provided on the second adjustment ring 5. Such a structural design allows the gasket 2 to be synchronously raised with the second adjustment ring 5 through the cooperation of the gear 8 and the rack when the second adjustment ring 5 is raised driven by the first adjustment ring 4. In this way, the raising of the second adjustment ring 5 and the gasket 2 can achieve double-layer height adjustment under the same power source, i.e., the rotation of the toothed disk 3. At the same time, without the gasket 2 being raised, the gasket 2 can also be retracted into the casing 102 together with the second adjustment block, thereby reducing the space occupied by the adjustable pad of the paper tray rack and adapting to various specifications of tipping paper tubes.

[0034] In some optional embodiments, the adjustable pad of the paper tray rack further includes a positioning mechanism, and the positioning mechanism includes a positioning rod 901 connected to the casing 102, and a positioning block 902 is welded to the positioning rod 901;

[0035] When the positioning rod 901 is lifted, the toothed disc 3 is in an active state;

[0036] When the positioning rod 901 is lowered, the positioning block 902 is stuck in the tooth groove of the toothed disk 3. With such a structural design, through the positioning rod 901 and the positioning block 902, when the adjustable pad of the paper tray rack is at an ideal height, the rotation of the toothed disk 3 can prevent the user from accidentally touching it, or the toothed disk 3 rotates with the rotation of the tipping paper tube during operation, resulting in an unexpected change in the height of the adjustable pad of the paper tray rack. The structure is simple and has strong practicality.

[0037] The cork paper tube is usually sleeved on a cylindrical paper tray rack, and the lower end of the paper tray rack is usually provided with a rotating seat that drives the paper tray rack to rotate. Since the overall structure of the adjustable pad of the paper tray rack proposed in this embodiment is annular, during installation, the adjustable pad of the paper tray rack can be directly sleeved on the paper tray rack and fixed on the rotating seat. It is understandable that due to the different width specifications of the cork paper tube and the different base heights of the rotating seat, if in actual application the lowest height of the adjustable pad of the paper tray rack proposed in this embodiment when converged is greater than the minimum required height of the cork paper tube, the adjustable pad of the paper tray rack can be embedded and installed in the rotating seat. The installation height of the adjustable pad of the paper tray rack is not specifically limited here, and it can be flexibly set according to actual conditions.

[0038] When the present embodiment is in use, the positioning rod 901 is first lifted, and then the toothed disk 3 is rotated manually or by a mechanism such as a servo motor, and the first adjusting ring 4 is driven to rotate by the toothed disk 3, so that the second adjusting ring 5 slowly rises under the cooperation of the external thread of the first adjusting ring 4 and the internal thread of the second adjusting ring 5. During the rising process of the second adjusting ring 5, the gear 8 provided on the second adjusting ring 5 rotates counterclockwise under the restriction of the rack structure 7 on the inner side of the sleeve 102, so that the washer 2 with the rack structure 7 on the outer side is driven to rise upward by the counterclockwise rotating gear 8. When the washer 2 is at an ideal height, the rotation of the toothed disk 3 is stopped and the positioning rod 901 is lowered, and the toothed disk 3 is locked by the positioning block 902 on the positioning rod 901 to prevent accidental touch.

[0039] The above is a detailed introduction to an adjustable pad block for a paper tray rack provided by the utility model. The description of the specific embodiment is only used to help understand the method and core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
