Description

Technical Field

[0001] The utility model belongs to the field of cigarette manufacturing equipment, and particularly relates to a novel transparent paper conveying automatic tensioning device for a YB515 type packaging machine. Background Art

[0002] As a special cigarette packaging equipment, the transparent paper conveying device of the YB515 type packaging machine works as follows: the conveying of the transparent paper mainly relies on the conveying steel roller and the conveying rubber roller arranged thereon to clamp the transparent paper, apply a pressing force, and then realize the conveying and unfolding of the transparent paper through the relative rotation of the conveying rollers. At the same time, it drags the transparent paper reel installed on the paper rack to realize the continuous unwinding of the transparent paper. In addition, multiple winding rollers are provided to reduce the conveying tension, and a magnetic excitation brake generates a certain braking force on the unwinding rotation speed of the transparent paper rack according to the actual running speed of the packaging equipment, so that the transparent paper in the conveying process is always unfolded flat without slack.

[0003] However, during the working process of the YB515 type packaging machine, when the equipment suddenly stops from a high-speed state, the magnetic excitation brake fails to brake in time, which will cause the transparent paper to slack. The slack transparent paper is easy to contact the high-temperature splicing soldering iron, resulting in wrinkles, affecting the product quality, and may cause unstable conveying and skewed unfolding position of the transparent paper roll when the equipment is restarted, increasing the rejection rate and the number of equipment shutdowns.

[0004] Therefore, in order to solve the problem of the transparent paper slack when the YB515 type packaging machine suddenly stops, it is urgent to design an automatic transparent paper conveying tensioning device, which can automatically tighten the slack part of the transparent paper when the transparent paper slackens by reaching the unfolded state of the transparent paper. Summary of the Utility Model

[0005] In order to solve the problem that in the working conveying process of the YB515 type packaging machine in the above-mentioned prior art, it is found that there is a fault of transparent paper slack in the unwinding work of the transparent paper conveying device, which poses a certain hidden danger to the product packaging quality. This technical solution proposes an innovative novel transparent paper conveying automatic tensioning device for the YB515 type packaging machine, aiming to provide a device that can automatically adjust and maintain the tension state of the transparent paper to keep the transparent paper in a stable tension state even in the shutdown state during the conveying process.

[0006] A novel transparent paper conveying automatic tensioning device for a YB515 type packaging machine provided by the utility model has the following specific technical solutions, including: a swing arm mechanism, a tensioning arm, and a counterweight arm;

[0007] The swing arm mechanism is rotatably sleeved on the winding roller shaft, and a tensioning arm and a counterweight arm are arranged on the swing arm mechanism along the radial direction of the winding roller shaft;

[0008] A tensioning roller shaft is further arranged on the tensioning arm along the axial direction of the winding roller shaft. The tensioning roller shaft is arranged parallel to the winding roller shaft, and a tensioning roller is movably sleeved on the tensioning roller shaft; a counterweight roller is arranged on the counterweight arm;

[0009] The counterweight roller drives the swing arm mechanism to rotate around the winding roller shaft, drives the tensioning roller to abut against the surface of the transparent paper, and keeps the transparent paper in a tensioned state.

[0010] Preferably, the tensioning roller shaft is detachably connected to the tensioning arm.

[0011] Preferably, the counterweight roller is connected to the counterweight arm through a counterweight roller shaft.

[0012] Preferably, the counterweight roller shaft is detachably connected to the counterweight arm.

[0013] Preferably, the counterweight roller is sleeved on the outer surface of the counterweight roller shaft, and the relative distance of the counterweight roller relative to the counterweight arm is adjustable.

[0014] Preferably, the tensioning arm and the counterweight arm are perpendicularly arranged on the swing arm mechanism.

[0015] Preferably, a positioning bushing is further arranged at one end of the tensioning roller shaft away from the tensioning arm, and the positioning bushing is used to limit the tensioning roller.

[0016] Preferably, in one embodiment, the new transparent paper conveying automatic tensioning device of the YB515 type packaging machine further includes a limit ring connected to the swing arm mechanism. The limit ring is sleeved on the winding roller shaft, and the limit ring is used to limit the rotation angle of the swing arm mechanism.

[0017] Preferably, the specific structure of the limit ring further includes a stud arranged on the swing arm mechanism. The limit ring is provided with an opening structure, and the rotation angle of the swing arm mechanism is limited through the opening structure on the limit ring and the stud on the swing arm mechanism.

[0018] Preferably, the limit ring is detachably arranged on the winding roller shaft.

[0019] This solution proposes an automatic tensioning device for the new transparent paper conveying of the YB515 type packaging machine;

[0020] Compared with the existing conveying device, the automatic tensioning device provided by this solution does not need to transform the original conveying device and can be installed using the existing conditions;

[0021] It can be seen that the beneficial effects of the present utility model are:

[0022] (1) Simple structure: The automatic tensioning device only needs to be installed by using a paper winding roller shaft of the original machine;

[0023] (2) Reliable use: Relying on its own structural characteristics, the automatic tensioning device can, in the state of the equipment running or stopping and without relying on any power source, use the principle of unbalanced weight to automatically tension the loose transparent paper;

[0041] Please refer toFigures 1 to 5 , for the technical solution of the present utility model, a novel transparent paper conveying automatic tensioning device of a YB515 type packaging machine is specifically described. Its specific structure includes: a swing arm mechanism 1, a tensioning arm 2, and a counterweight arm 3;

[0042] As Figure 6 shown in Figure 7 , during the conveying process of the novel transparent paper of the YB515 type packaging machine in the prior art, a winding roller is arranged on the winding roller shaft 4 to abut against the outer surface of the transparent paper, so as to reduce the conveying pressure of the transparent paper;

[0043] However, for the automatic tensioning device provided by the present utility model, an automatic tensioning device is set by using the existing conditions of the winding roller shaft 4. As Figure 2 shown in Figure 5 , at the idle part of the end of the winding roller shaft 4, the swing arm mechanism is rotatably sleeved on the winding roller shaft 4, and the tensioning arm 2 and the counterweight arm 3 are arranged on the swing arm mechanism along the radial direction of the winding roller shaft 4;

[0044] A tensioning roller shaft 5 is further arranged on the tensioning arm 2 along the axis direction of the winding roller shaft 4. The tensioning roller shaft 5 is arranged in parallel with the winding roller shaft 4, and a tensioning roller 6 is movably sleeved on the tensioning roller shaft 5; a counterweight roller 7 is arranged on the counterweight arm 3;

[0045] The counterweight roller drives the swing arm mechanism 1 to rotate around the winding roller shaft 4, drives the tensioning roller 6 to abut against the surface of the transparent paper, and keeps the transparent paper in a tensioned state;

[0046] It can be understood that the working principle of the automatic tensioning device provided by the present application is to utilize the principle of weight imbalance. With the original machine's one paper winding roller shaft as the axis, the weights on the left and right ends of the swing arm mechanism are unbalanced. Specifically, the light end is the tensioning roller 6, and the heavy end is the counterweight roller. Under the gravity of the counterweight roller, the tensioning roller 6 always tilts towards the heavy side, so as to abut against the transparent paper and realize the tensioning action on the transparent paper; at the same time, due to using its own weight property, after the equipment stops suddenly and loses power, it can still perform the tensioning action on the loose transparent paper.

[0047] Preferably, the structure of the tensioning roller shaft 5 in this embodiment is further limited. The tensioning roller shaft 5 is detachably connected to the tensioning arm 2. Specifically, as Figure 5 shown in

[0048] Preferably, the structure of the counterweight roller in this embodiment is further defined as follows Figure 1 As shown, in this embodiment, the counterweight roller is connected to the counterweight arm 3 through the counterweight roller shaft 7. By providing the counterweight roller shaft 8, a connection structure is provided for the counterweight roller 7 and the counterweight arm 3, facilitating the connection

[0049] Furthermore, the structure of the counterweight roller shaft 8 in this embodiment is further defined as follows Figure 5 As shown, in this embodiment, one end of the counterweight roller shaft 8 is provided with a thread and is threadedly connected to the counterweight arm 3; through the detachable design of the counterweight roller shaft 8, when there is a tensioning requirement for transparent paper with different conveying speeds, it can be replaced in a timely manner to adapt to different usage scenarios

[0050] Still further, the structure of the counterweight roller in this embodiment is further defined as follows Figure 1 As shown, in this embodiment, the counterweight roller 7 is sleeved on the outer surface of the counterweight roller shaft 8, and the relative distance of the counterweight roller 7 relative to the counterweight arm 3 is adjustable

[0051] It can be understood that, according to the mechanical principle, by adjusting the relative distance of the counterweight roller 7 relative to the counterweight arm 3, it is equivalent to adjusting the force arm on one side of the counterweight arm 3. In relative cooperation with the detachable design of the counterweight roller 7, it can flexibly respond to the tensioning requirements of transparent paper with different conveying speeds. When only the distance needs to be adjusted, the step of replacing the weight of the counterweight roller 7 is omitted, improving the convenience of equipment use

[0052] As a preference, the connection relationship between the tensioning arm 2 and the counterweight arm 3 in this embodiment is further defined as follows Figure 1 、 Figure 2 、 Figure 5 As shown, in this embodiment, the tensioning arm 2 and the counterweight arm 3 are perpendicularly arranged on the swing arm mechanism 1

[0053] It can be understood that, according to the mechanical principle, when the rotation directions of two interconnected levers are perpendicular to each other, their respective force arms can easily reach the maximum length. This is because, in the case of perpendicular rotation, the force can be applied along the direction perpendicular to the rotation direction of the lever, so the force arm is the longest distance of the lever itself in this direction; therefore, in this embodiment, the tensioning arm 2 and the counterweight arm 3 are perpendicularly arranged to utilize the principle of maximizing their own gravity

[0054] As a preference, the structure of the tensioning roller 6 in this embodiment is further defined as follows Figure 5As shown, in this embodiment, the tension roller 6 is rotatably sleeved on the outer surface of the tension roller shaft 5 for abutting against the surface of the transparent paper to apply tension. To prevent the tension roller 6 from moving axially along the tension roller shaft 5 during the rotational abutment process, a positioning sleeve 9 is further provided at one end of the tension roller shaft 5 away from the tension arm 2. By abutting against the end face of the tension roller 6 with the positioning sleeve 9, the tension roller 6 is limited in the axial direction along the tension roller shaft 5.

[0055] Preferably, to enable the tension roller 6 to lightly contact the vertically unfolded transparent paper when not in the tensioning working state, without adversely affecting the conveying and unfolding of the transparent paper, and to provide an angular restraint for the automatic tensioning device that has completely fallen to the side of the counterweight roller when the transparent paper is completely withdrawn, without affecting other components around the YB515 type packaging machine. In this embodiment, as Figure 3 、 Figure 4 、 Figure 5 shown, a limit ring 10 connected to the swing arm mechanism 1 is further provided on the winding roller shaft 4. The limit ring 10 is sleeved on the winding roller shaft 4, and the limit ring 10 is used to limit the rotation angle of the swing arm mechanism 1.

[0056] Better, the specific structure of the limit ring 10 in this embodiment is further defined. As Figure 3 、 Figure 4 、 Figure 5 shown, in this embodiment, the specific structure of the limit ring 10 further includes a stud 11 provided on the swing arm mechanism 1. The limit ring 10 is correspondingly provided with an opening structure. Through the opening structure on the limit ring 10, rotational limitation is carried out with the stud 11 on the swing arm mechanism 1 to achieve the limitation of the rotation angle of the swing arm mechanism 1.

[0057] Furthermore, the specific structure of the limit ring 10 in this embodiment is further defined. The limit ring 10 is detachably arranged on the winding roller shaft 4. Through the detachable design, it is possible to select a suitable opening angle setting of the limit ring 10 according to different winding roller settings. As Figure 3 、 Figure 4 、 Figure 5 shown, specifically in this embodiment, mounting holes are provided on the outer surface of the limit ring 10. By passing bolts through the mounting holes to abut against the winding roller shaft 4, the connection and fixation of the limit ring 10 are achieved.

[0058] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to the embodiments shown herein, but rather to the broadest scope consistent with the principles and novel features disclosed herein.
