Description

Technical Field

[0001] This utility model relates to the field of cigarette equipment technology, and in particular to a filter tip assembly machine and a cigarette rolling unit. Background Technology

[0002] A cigarette making machine is a device used to process cigarettes, mainly consisting of a filter tip filling machine. The filter tip filling machine primarily includes a convergence wheel and two floats. The convergence wheel has grooves for sequentially placing one cigarette, a double-length filter tip, and another cigarette. The two floats are located at opposite ends of the convergence wheel. By adjusting the positions of the two floats, the cigarette and the double-length filter tip can be brought together and aligned within the grooves of the convergence wheel.

[0003] In existing cigarette making machines, the float ring remains compressed after installation. A rubber ring is typically placed between the adductor wheel and the float ring, serving as a connection and providing compressive elasticity. The drawbacks of this type of machine include: the rubber ring, being made of rubber, is prone to cracking under prolonged deformation pressure and cannot be repaired, resulting in a short service life.

[0038] This embodiment discloses a filter tip attaching machine and a cigarette making machine unit including the filter tip attaching machine, which can be, but is not limited to, the ZJ112 cigarette making machine unit MAX filter tip attaching machine.

[0039] like Figures 1 to 3 As shown, the filter tip attaching machine includes a convergence wheel assembly 1, two float rings 2, and two sets of elastic ring assemblies made of metal. The convergence wheel assembly 1 is provided with a smoke receiving groove 12 for accommodating cigarettes and double-length filters. The two float rings 2 are respectively located at both ends of the convergence wheel assembly 1, and the smoke receiving groove 12 is located between the two float rings 2. One set of elastic ring assemblies is connected between one end of the convergence wheel assembly 1 and one float ring 2, and the other set of elastic ring assemblies is connected between the other end of the convergence wheel assembly 1 and the other float ring 2.

[0040] The existing rubber rings are replaced with elastic ring components made of metal materials, which have a longer service life, reduce the frequency of replacement of spare parts, and provide a better user experience; it can be used without changing the structure of the existing approach wheel assembly 1 and float ring 2, and the modification is easy.

[0041] The specific structure of the elastic coil assembly is not limited, such as Figures 3 to 6 As shown, each set of elastic ring assemblies includes at least two stacked metal floats 3. Each metal float 3 includes an annular main body 31 and at least two elastic plates 32. A slit notch 33 is formed between the elastic plate 32 and the main body 31. One of the main body 31 and the elastic plate 32 is connected to the approach wheel assembly 1, and the other of the main body 31 and the elastic plate 32 is connected to the float 2. That is, the elastic plate 32 has a long strip structure, and the elastic plate 32 is connected to the main body 31. The elastic plate 32 can be tilted at a certain angle relative to the plane of the main body 31, thereby changing the distance between the end of the approach wheel assembly 1 and the float 2 to adjust the position of the cigarette and the filter, so that the midpoint of the cigarette and the filter is aligned with the midpoint of the approach wheel assembly 1.

[0042] Based on the above structure, the approaching wheel assembly 1 is provided with a wheel connection hole 11, each float ring 2 is provided with a float ring connection hole 21, the main body 31 is provided with a main body connection hole 34, and the elastic plate 32 is provided with a plate connection hole 35. One of the main body connection hole 34 and the plate connection hole 35 is connected to the approaching wheel assembly 1 through the wheel connection hole 11, and the other of the main body connection hole 34 and the plate connection hole 35 is connected to the float ring 2 through the float ring connection hole 21. When the distance between the approaching wheel assembly 1 and the float ring 2 changes, the tilt angle of the elastic plate 32 relative to the plane of the main body 31 changes accordingly, realizing elastic deformation.

[0043] The specific structure that changes the distance between the approach wheel assembly 1 and the float 2 is not limited; in this embodiment, for example... Figure 1 , Figure 7 , Figure 8 and Figure 11 As shown, the filter nozzle assembly machine also includes an adjustment mechanism 4. The adjustment mechanism 4 includes a main shaft 41 and two adjustment arms 42 spaced apart on the main shaft 41. The adjustment arms 42 are provided with mounting through holes 423, and the main shaft 41 passes through the mounting through holes 423 with an interference fit.

[0044] The adjusting arm 42 is equipped with a roller 421, which abuts against the outer end face of the float ring 2. The roller 421 and the float ring 2 have a rolling fit, resulting in low wear. Shortening the distance between the two adjusting arms 42 will correspondingly shorten the distance between the two float rings 2; increasing the distance between the two adjusting arms 42 will correspondingly increase the distance between the two float rings 2.

[0045] The two floating rings 2 are controlled synchronously. As they move closer to each other and further away from each other, each floating ring 2 moves an equal distance, keeping the position of the virtual center of the two floating rings 2 (a point equidistant from the two floating rings 2) unchanged.

[0046] The specific structure for achieving equal movement distance for each float 2 is not limited. In this embodiment, the adjustment mechanism 4 includes an adjustment component 43 for adjusting the distance between the two adjustment arms 42. Figures 7 to 10 As shown, the adjustment assembly 43 includes an adjustment knob 431, a drive rod 432, and two screws 433. The adjustment arm 42 has a threaded hole 422 for the screws 433 to pass through. The adjustment knob 431 is connected to the drive rod 432, and the drive rod 432 can rotate synchronously with the adjustment knob 431. The drive rod 432 is respectively connected to the two screws 433, and the drive rod 432 can drive the two screws 433 to rotate synchronously. When the screws 433 rotate, the two adjustment arms 42 move closer to each other or further away from each other, and the position of the midpoint between the two adjustment arms 42 remains unchanged.

[0047] The adjusting knob 431 can be, but is not limited to, a 10mm diameter hexagonal nut. When it is necessary to adjust the distance between the two adjusting arms 42, the adjusting knob 431 can be easily rotated with a wrench, which is labor-saving. After the adjustment is completed, the wrench can be removed. The adjusting knob 431 occupies little space and avoids contact with surrounding objects.

[0048] To ensure stable contact between the drive rod 432 and the two screws 433, the adjustment assembly 43 also includes a three-way bracket 434. The drive rod 432 and the two screws 433 each pass through an opening in the three-way bracket 434. The three-way bracket 434 has a locking hole 435, in which a locking screw passes to prevent the screws 433 from rotating accidentally under the drive of the drive rod 432, thus enhancing safety.

[0049] The specific structure by which the drive rod 432 drives the two screws 433 to rotate is not limited. In this embodiment, the drive rod 432 and the screws 433 are connected by bevel gear meshing. When the drive rod 432 is vertically set, the two screws 433 are horizontally set and located on opposite sides of the drive rod 432.

[0050] There are two main structures for achieving the connection between the drive rod 432 and the screw 433 through bevel gear meshing: In one structure, a bevel gear is provided at the bottom end of the drive rod 432, and bevel gears are provided at the ends of the two screws 433 respectively. The bevel gear of the drive rod 432 meshes with the bevel gears of the two screws 433 respectively, so as to realize the transmission from the drive rod 432 rotating around a vertical line to the screw 433 rotating around a horizontal line.

[0051] In another structure, a bevel gear is provided at the bottom of the drive rod 432, and the two screws 433 are connected into an integral structure. A bevel gear is sleeved on the integral structure. The bevel gear of the drive rod 432 meshes with the bevel gear on the integral structure, and the two screws 433 can rotate synchronously, so that the two adjusting arms 42 can move synchronously.

[0052] Based on the above structure, such as Figure 7 and Figure 10 As shown, the main shaft 41 includes an outer sleeve 411, an inner rod 412 passing through the outer sleeve 411, and a rotating part 413 connected to the inner rod 412. The rotating part 413 can drive the inner rod 412 to rotate around an axis. The inner rod 412 is fixedly mounted on the machine base. When the inner rod 412 rotates around the axis, it can drive the outer sleeve 411 to move along the axial direction, thereby changing the spatial position of the outer sleeve 411. The rotating part 413 can be, but is not limited to, a knurled handle. The knurling increases the friction between the hand and the rotating part 413, making it easier to grip and use.

[0053] The specific structure that enables the inner rod 412 to rotate around its axis and drive the outer sleeve 411 to move along the axial direction is not limited; any existing structure that can achieve the function can be used. In this embodiment, the outer sleeve 411 and the inner rod 412 are engaged with a pin through a U-shaped elongated hole. A 100mm long compression spring is installed inside the outer sleeve 411, and the compression spring abuts against the inner rod 412. The rotation of the rotating part 413 drives the internal thread to engage with the compression spring, thereby achieving synchronous movement of the two adjusting arms 42 in the same direction, and the two floats 2 correspondingly move synchronously in the same direction.

[0054] Based on the above structure, a through hole 414 is provided on the main spindle 41, and the drive rod 432 passes through the through hole 414. The adjustment knob 431 and the screw 433 are located on opposite sides of the main spindle 41, respectively. The spatial position of the overall structure of the adjustment assembly 43 is more stable. The main spindle 41 and the adjustment assembly 43 form an assembly, which improves the structural strength and extends the service life.

[0055] During cigarette manufacturing, the cigarette and the double-length filter tip are placed in the cigarette receiving groove 12 of the approaching wheel assembly 1. The floating ring 2 aligns the cigarette and the double-length filter tip with the center of the approaching wheel assembly 1, which is basically aligned with the cutter. The paper cutting wheel attaches the glued splicing paper to the cigarette and the double-length filter tip, and the cigarette rolling wheel rolls them together to form a double-length filter cigarette. The conveying wheel transports the double-length filter cigarette to the secondary cutting wheel, where the cutter cuts the double-length filter cigarette into two filter cigarettes of equal length. The transmission wheel then transports the cut filter cigarettes to the turning wheel, which adjusts the opposing (forward / backward) filter cigarettes to face the same direction.

[0056] In the process of attaching the tipping paper to the cigarette and the double-length filter, existing cigarette rolling machines have a support pin on the approach wheel assembly 1. When bonding is needed, the support pin pushes the tipping paper onto the cigarette and the double-length filter, and the adhesive sticks to the support pin, requiring frequent cleaning or replacement, which is inconvenient. In this embodiment, the support pin is removed, and an air vent is opened on the outer wall of the approach wheel assembly 1. High-pressure air can be blown onto the tipping paper through the air vent, thereby causing the tipping paper to adhere to the cigarette and the double-length filter, solving the problem of needing to frequently clean or replace the support pin.

[0057] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
