Description

Technical Field

[0001] The utility model relates to the technical field of cigarette packaging machines, in particular to a drum float kit for cigarette packaging machines. Background Art

[0002] When adjusting cigarette length on high-speed cigarette making machines, it's necessary to inspect the front and back surfaces of the float rings 5 at both ends of the draw drum 2 for cleanliness and, if necessary, replacement. The float rings 5 are located on the draw drum 2, with one on the inside and the other on the outside. Neither can be inspected directly; the drum must be disassembled for inspection.

[0003] like Figure 1 As shown, the drawing drum 2 is topped by a paper cutting wheel 3, and flanked by a joining drum 1 and a splicing drum 4. All three drums are arc-shaped, with a slightly raised center. A floating ring 5 is provided with an arc-shaped notch, located at the position corresponding to the paper cutting wheel 3, and used to position the floating ring 5. Due to the shapes of the floating ring 5, the joining drum 1, and the splicing drum 4, and the presence of floating rings 5 on both the inside and outside of the drawing drum 2, if the drawing drum 2 is removed alone, the floating ring 5 will be affected by the raised portions of the joining drum 1 and the splicing drum 4, making it difficult to remove smoothly. Therefore, to remove the drawing drum 2, the adjacent joining drum 1 and the splicing drum 4 must be removed first, complicating the disassembly process and preventing operators from completing the task independently. After cleaning or replacing the floating ring 5, the distance between the drawing drum 2, the joining drum 1, and the splicing drum 4 must be fine-tuned when installing the three drums. This prolongs maintenance time and increases the waiting time for other cigarette machine repairs, reducing the equipment's operational efficiency. Utility Model Content

[0004] In view of the above problems, the utility model provides a cigarette making machine drum float ring kit, which can effectively simplify the float ring disassembly and assembly process, and improve the equipment maintenance efficiency and equipment effective operation rate.

[0005] Specifically, the utility model provides a cigarette making machine drum float kit, comprising:

[0006] Two floating rings are symmetrically arranged on the inner and outer sides of the drum, and are provided with a first arc-shaped opening, a second arc-shaped opening, and a third arc-shaped opening. The first arc-shaped opening is located near the paper cutting wheel, the second arc-shaped opening is located near the splicing drum, and the third arc-shaped opening is located near the converging drum.

[0007] The positioning member is used to position the two floats when installing the floats. The positioning member includes:

[0008] The support portion is placed in the smoke receiving groove close to the drum surface when in use;

[0009] Two connecting parts are respectively located at two ends of the supporting part and are used to connect the floating ring.

[0010] Furthermore, the diameter of the connecting portion is smaller than the diameter of the circular hole on the float ring. When in use, the connecting portion penetrates into the circular hole on the float ring, and the length of the protruding portion is smaller than the length of the non-protruding portion.

[0011] Furthermore, any one of the connecting parts is configured as a retractable structure.

[0012] Furthermore, any one of the connecting parts extends into the supporting part, and a spring is provided between the connecting part and the supporting part.

[0013] Furthermore, a central angle between the first arc-shaped opening and the second arc-shaped opening is 90°, and a central angle between the first arc-shaped opening and the third arc-shaped opening is 135°.

[0014] Furthermore, the support portion is adapted to the smoke receiving groove close to the drum surface.

[0015] Working principle:

[0016] The second and third arc-shaped openings are newly added on the floating ring to move the merging drum and the splicing drum away, so that the approaching drum and the floating ring can be removed smoothly without being blocked by the merging drum and the splicing drum. Therefore, when disassembling and assembling the floating ring, there is no need to disassemble and assemble the merging drum and the splicing drum.

[0017] When installing the float ring, first install the positioning piece into any smoke receiving groove on the disassembled approach drum. Then, install the float rings on the inner and outer sides of the approach drum. During installation, insert the connecting parts of the positioning piece into the circular holes on the left or right side of any arc-shaped openings on the inner and outer float rings, aligning the front and back of the float rings. Position the front and back float rings so that the three arc-shaped openings on the two float rings are aligned. Then, push the positioning piece forward or backward to disengage the connecting part from the circular holes on the float rings. Remove the positioning piece and install the approach drum on the equipment.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) The utility model provides a cigarette making machine drum float ring kit, which eliminates the need to disassemble and assemble the adjacent splicing drum and merging drum when inspecting and replacing the float ring, thereby greatly simplifying the disassembly and assembly process, reducing the difficulty of disassembly and assembly, and improving the disassembly and assembly efficiency.

[0020] (2) When installing the float ring, the smoke bearing groove close to the drum surface is used as a reference, and the positioning parts can be used to achieve the positioning installation of the front and rear float rings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The present invention will be further described in detail below through specific implementations in conjunction with the accompanying drawings.

[0030] Example 1

[0031] like Figure 2 As shown, this embodiment provides a floating ring kit for a closing drum of a cigarette making machine, comprising: two floating rings 5 and a positioning member 6. The two floating rings 5 are symmetrically arranged on the inner and outer sides of the closing drum 2. The floating rings 5 are provided with a first arcuate opening 51, a second arcuate opening 52, and a third arcuate opening 53. The central angle between the first and second arcuate openings 51, 52 is 90°, and the central angle between the first and third arcuate openings 51, 53 is 135°. This allows the first arcuate opening 51 to correspond with the paper cutting wheel 3, the second arcuate opening 52 to correspond with the splicing drum 4, and the third arcuate opening 52 to correspond with the merging drum 1. The first, second, and third arcuate openings 51, 52 are staggered relative to the raised positions between the paper cutting wheel 3, the splicing drum 4, and the merging drum 1. This allows the closing drum 2 equipped with the floating rings 5 to be disassembled and assembled without disassembling the merging drum 1 and closing drum 2, greatly improving the efficiency of disassembly and assembly of the floating rings 5 and closing drum 2.

[0032] like Figure 3As shown, the positioning member 6 includes: a support portion 61 and two connecting portions 62. The support portion 61 is cylindrical and is adapted to the smoke receiving groove 21 on the surface of the close drum 2 so that it can be placed in the smoke receiving groove 21. The connecting portion 62 is located at the end of the support portion 61. Its diameter is smaller than the diameter of the circular hole 54 on the float ring 5. When in use, the connecting portion 62 penetrates the circular hole 64, and the length of the protruding portion is smaller than the length of the non-protruding portion, so that after the positioning member 6 moves axially, the connecting portion 62 at one end can be detached from the circular hole 64, thereby removing the positioning member 6. After the close drum 2 is removed, when replacing the float ring 5, as shown in FIG. Figure 4 As shown, first install the support portion 61 of the positioning member 6 into any smoke receiving groove 21 on the disassembled approach drum 2. Then, install the inner float ring 5 on the inner side of the approach drum 2, with the connecting portion 62 inserted into the circular hole 54 on the left or right side of any arc-shaped opening. After the inner float ring 5 is installed and secured, install the outer float ring 5. During installation, the circular hole 54 is positioned corresponding to the inner float ring 5, and the outer float ring 5 is then secured. Next, push the positioning member 6 forward or backward in the axial direction to disengage the connecting portion 62 at one end from the circular hole 54. Then remove the positioning member 6, and finally, install the approach drum 2 on the equipment.

[0033] Example 2

[0034] Based on Example 1, any one of the connecting portions 62 extends into the end of the support portion 61, with a spring 63 interposed therebetween. A retaining pin 64 is also provided on the connecting portion 62 to prevent it from coming out. Specifically, after installing the float 5, to remove the positioning member 6, first press the positioning member 6 to prevent it from moving, then press the connecting portion 62 to release it from the circular hole 54, and then remove the positioning member 6.

[0035] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. Those skilled in the art of the present invention can make some simple deductions, modifications or substitutions based on the concept of the present invention.
