A device for preventing tipping of cigarette machine paper.

Abstract

This utility model discloses a cigarette machine tipping paper anti-deviation device, belonging to the field of cigarette machine technology. Its key technical features include a connecting plate with anti-deviation mechanisms welded to both sides of the top rear side of the connecting plate. An auxiliary mechanism is welded to the top of the connecting plate. The anti-deviation mechanism is driven by a servo motor to rotate the lead screw, causing the anti-deviation ring to move synchronously along the paper feeding roller axis. This allows for quick adaptation to tipping papers of different widths, solving the problem that traditional fixed limiting structures cannot accommodate multiple specifications of tipping paper, thus improving the equipment's versatility. The anti-deviation rings on both sides form a physical barrier, directly limiting the left and right deviation of the tipping paper during the paper feeding stage. Combined with the rigid support of the support shell and connecting shaft, this ensures no shaking during lead screw transmission, avoiding secondary deviation caused by mechanism vibration and reducing the risk of deviation during high-speed conveying. The bottom of the anti-deviation ring is connected to the lead screw via a moving plate, resulting in high transmission efficiency and good self-locking, ensuring stable maintenance of the anti-deviation ring position.

Description

Technical Field

[0001] This utility model relates to the field of cigarette machine technology, and in particular to a device for preventing tipping of cigarette machine paper. Background Technology

[0002] The tipping paper anti-deviation device is a core auxiliary equipment on the cigarette machine production line. It is specifically designed to solve the deviation problem of tipping paper caused by factors such as tension fluctuations, equipment vibration, and material characteristics during the conveying and rolling process. Through functions such as mechanical limit, dynamic monitoring, and automatic correction, it ensures that the tipping paper is always conveyed accurately along the preset path, and finally achieves a stable and regular connection between the tipping paper and the filter tip.

[0003] To address the aforementioned issues, existing patents have provided solutions. However, existing cigarette rolling machines lack a structure to prevent the tipping paper from shifting. This leads to problems such as left-right shifting, edge wrinkling, and misalignment of filter rods or cigarette strips during high-speed conveying due to factors such as tension fluctuations, equipment vibration, or drum eccentricity. Consequently, the precision of the tipping paper's wrapping and bonding with the filter rod is reduced.

[0004] To address this, a device for preventing tipping of cigarette paper in cigarette machines is proposed. Utility Model Content

This reduces the accuracy of the wrapping and bonding of tipping paper and filter rods.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cigarette machine tipping paper anti-deviation device, comprising a connecting plate, with anti-deviation mechanisms welded to both sides of the top rear side of the connecting plate, and an auxiliary mechanism welded to the top of the connecting plate. The anti-deviation mechanism includes a support beam, a paper feeding roller, two anti-deviation rings, a moving plate, a support shell, a connecting shaft, a lead screw, and a servo motor. The support beams are welded to both sides of the top rear side of the connecting plate, the paper feeding roller is rotatably connected between the two support beams, the anti-deviation rings are movably connected to both sides of the surface of the paper feeding roller, the moving plate is welded to the bottom of the anti-deviation rings, the support shell is welded between the two support beams, the connecting shaft is installed inside the support shell, and the lead screw is welded to both sides of the connecting shaft and rotatably connected to the inside of the support shell.

[0007] Preferably, the bottom of the connecting plate is provided with a threaded hole, which is threaded to the surface of the lead screw. The left side of the lead screw is connected to a connecting shaft via a flat key. The servo motor is installed on the left side of the left support beam. The output end of the servo motor on the right side passes through the support beam and the support shell and is fixedly connected to the left side of the connecting shaft.

[0008] Preferably, the auxiliary mechanism includes a fixed beam, three sets of limiting rollers, a fixed ring, several return springs, a pressure sensor, a contact ring, a PLC controller, and a buzzer alarm, with the fixed beam welded to the top of the connecting plate.

[0009] Preferably, the limiting roller is rotatably connected to the top of the inner side of the fixed beam, the fixed ring is welded to both sides of the limiting roller, the reset spring is installed on the surface of the fixed ring, and the pressure sensor is installed on the surface of the fixed ring.

[0011] Preferably, the inner side of the connecting plate has four fixing screw holes, and the inner side of the fixing screw holes is coated with anti-corrosion coating.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The anti-deviation mechanism of this application drives the lead screw to rotate via a servo motor, which drives the anti-deviation ring to move synchronously along the axial direction of the paper feeding roller. It can quickly adapt to different widths of tipping paper, solving the problem that the traditional fixed limit structure cannot be compatible with multiple specifications of tipping paper, improving the versatility of the equipment. The anti-deviation rings on both sides form a physical barrier, directly limiting the left and right deviation of the tipping paper during the paper feeding stage. With the rigid support of the support shell and the connecting shaft, it ensures that there is no shaking during the lead screw transmission process, avoiding secondary deviation caused by mechanism vibration, reducing the risk of deviation during high-speed conveying. The bottom of the anti-deviation ring is connected to the lead screw by a moving plate, which has high transmission efficiency and good self-locking, and can stably maintain the position of the anti-deviation ring.

[0016] 2. The auxiliary mechanism of this application uses three sets of limit rollers in conjunction with contact rings and return springs to achieve secondary limiting in the tipping paper conveying path. The contact rings are always in close contact with the edge of the tipping paper, and the lateral force generated by the deviation is sensed in real time, which makes up for the monitoring blind spot of relying solely on the paper feeding end for deviation prevention. The pressure sensor converts the deviation force signal into an electrical signal and transmits it to the PLC controller. When the deviation exceeds the threshold, the buzzer alarm will sound in time to remind the operator to intervene and avoid the generation of batches of defective products.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 The present invention provides the following technical solution:

[0025] A cigarette machine tipping paper anti-deviation device includes a connecting plate 1. Anti-deviation mechanisms 2 are welded to both sides of the top rear side of the connecting plate 1. An auxiliary mechanism 3 is welded to the top of the connecting plate 1. The anti-deviation mechanism 2 includes a support beam 21, a paper feeding roller 22, two anti-deviation rings 23, a moving plate 24, a support shell 25, a connecting shaft 26, a lead screw 27, and a servo motor 28. The support beam 21 is welded to both sides of the top rear side of the connecting plate 1. The paper feeding roller 22 is rotatably connected between the two support beams 21. The anti-deviation rings 23 are movably connected to both sides of the surface of the paper feeding roller 22. The moving plate 24 is welded to the bottom of the anti-deviation rings 23. The support shell 25 is welded between the two support beams 21. The connecting shaft 26 is installed inside the support shell 25. The lead screw 27 is welded to both sides of the connecting shaft 26 and is rotatably connected to the inside of the support shell 25.

[0026] In this embodiment: by setting a connecting plate 1 with an anti-deviation mechanism 2 and an auxiliary mechanism 3 welded to its top, and connecting the bottom to the main body of the cigarette machine, the integrated installation of the two core mechanisms is realized. The support beam 21 provides a stable rotation support point for the paper feeding roller 22 and the support shell 25. The paper feeding roller 22 is the direct bearing and conveying component of the tipping paper roll. The anti-deviation ring 23 is movably connected to both sides of the surface of the paper feeding roller 22, which can directly form a physical limit on the edge of the tipping paper and prevent the tipping paper from shifting to both sides during the paper feeding process. The moving plate 24 can ensure that the power of the screw 27 when rotating is transmitted to the anti-deviation ring 23, avoiding loosening or deviation during the transmission process. The support shell 25 supports and limits the connecting shaft 26 and the screw 27. The connecting shaft 26 can realize the synchronous rotation of the screws 27 on both sides, ensuring that the two anti-deviation rings 23 always maintain symmetrical movement during adjustment. The screw 27 converts the rotational motion of the servo motor 28 into the linear motion of the anti-deviation ring 23 through the threaded engagement with the moving plate 24. The servo motor 28 can provide rotational power for the screw 27.

[0027] Specifically, such as Figure 2 As shown, the bottom of the connecting plate 1 is provided with a threaded hole, which is threaded to the surface of the lead screw 27. The left side of the lead screw 27 is connected to the connecting shaft by a flat key. The servo motor 28 is installed on the left side of the left support beam 21. The output end of the servo motor 28 on the right side passes through the support beam 21 and the support shell 25 and is fixedly connected to the left side of the connecting shaft.

[0028] Specifically, such as Figure 3 , Figure 4 As shown, the auxiliary mechanism 3 includes a fixed beam 31, three sets of limit rollers 32, a fixed ring 33, several reset springs 34, a pressure sensor 35, a contact ring 36, a PLC controller 37, and a buzzer alarm 38. The fixed beam 31 is welded to the top of the connecting plate 1.

[0029] Specifically, such as Figure 3 , Figure 4As shown, the limiting roller 32 is rotatably connected to the top of the inner side of the fixed beam 31, the fixed ring 33 is welded to both sides of the limiting roller 32, the reset spring 34 is installed on the surface of the fixed ring 33, and the pressure sensor 35 is installed on the surface of the fixed ring 33.

[0030] In this embodiment: a fixed beam 31 provides a stable installation reference for the three sets of limiting rollers 32. The limiting rollers 32 are rotatably connected to the top inner side of the fixed beam 31, forming a multi-node guide path. During the conveying process, the tipping paper needs to pass through the three sets of limiting rollers 32 in sequence to correct the slight offset remaining at the paper feeding end, regulate the conveying trajectory, and avoid paper misalignment caused by long-distance conveying. The fixed ring 33 provides installation points for the return spring 34 and the pressure sensor 35. The return spring 34 continuously pushes the contact ring 36 to press tightly against the edge of the tipping paper through its own elastic tension. When the tipping paper shifts to one side, the pressure sensor 35 will squeeze the contact ring 36 on the corresponding side. The contact ring 36 can... The spring transmits pressure to the sensor, which converts the mechanical signal into an electrical signal and transmits it to the PLC controller 37 in real time. The contact ring 36 can move flexibly along the axial direction of the limit roller 32 and slide synchronously with the offset of the tipping paper to ensure the continuity of the monitoring signal and avoid monitoring failure caused by structural jamming. The PLC controller 37 can receive the electrical signal from the pressure sensor 35 and determine the degree of tipping paper offset through a preset program. The buzzer 38 can emit a high-decibel warning sound when the tipping paper offset exceeds the threshold, which can quickly attract the attention of operators in a noisy workshop environment. It is easier to be noticed than light warnings and avoids delays caused by operators not noticing the light.

[0031] Specifically, such as Figure 3 , Figure 4 As shown, the contact ring 36 is movably connected to the surface of the limit roller 32, and the surface of the contact ring 36 is fixedly connected to the side of the reset spring 34 away from the fixed ring 33. The PLC controller 37 is installed on the left side of the top of the connecting plate 1, and the buzzer alarm 38 is installed on the left side of the top of the connecting plate 1.

[0032] Specifically, such as Figure 3 As shown, four fixing screw holes 4 are provided on the inner side of the connecting plate 1, and the inner side of the fixing screw holes 4 is coated with anti-corrosion paint.

[0033] In this embodiment: by setting the fixing screw hole 4, it can be aligned with the preset mounting hole of the cigarette machine, and the device can be quickly fixed by bolts. By setting the anti-corrosion coating, the contact between moisture and dust and the metal screw hole can be effectively isolated, and rust can be avoided.

[0034] Specifically, such as Figure 4 As shown, the contact surfaces of the anti-deviation ring 23 and the contact ring 36 are both fixedly connected with protective pads 5, and the surface of the protective pads 5 is engraved with anti-slip textures.

[0035] Specifically, such as Figure 5 As shown, a shock-absorbing pad 6 is fixedly connected to the bottom of the connecting plate 1. The shock-absorbing pad 6 is made of nitrile rubber material, and several honeycomb shock-absorbing holes 7 are opened on the surface of the shock-absorbing pad 6.

[0036] In this embodiment: by setting the protective pad 5, the metal surfaces of the anti-deviation ring 23 and the contact ring 36 can be prevented from directly contacting the tipping paper, preventing the metal edges from scratching the printed layer on the tipping paper surface or causing the paper edges to fray or break, thus ensuring the appearance integrity and safety of the tipping paper. By setting the anti-slip texture, the coefficient of friction between the protective pad 5 and the tipping paper surface can be increased. By setting the shock-absorbing pad 6, the transmission of vibration can be reduced. The shock-absorbing pad 6 is made of nitrile rubber material, which has excellent elasticity and damping properties and can effectively absorb vibration energy. By setting the honeycomb shock-absorbing holes 7, vibration energy can be further dispersed and absorbed.

[0037] Working Principle: First, the operator connects the entire anti-deviation device to the main body of the cigarette machine via four fixing screw holes 4. Then, according to the width of the tipping paper to be produced, the operator starts the servo motor 28. The output end of the servo motor 28 drives the lead screw 27 to rotate through the connecting shaft. Since the lead screw 27 is threadedly engaged with the threaded hole of the bottom moving plate 24 of the anti-deviation ring 23, and the connecting shaft 26 ensures that the lead screws 27 on both sides rotate synchronously, the two anti-deviation rings 23 are eventually driven to move symmetrically along the axial direction of the paper feeding roller 22 until the spacing of the anti-deviation rings 23 matches the width of the tipping paper, completing the initial limit preparation. Next, the operator installs the tipping paper roll on the paper feeding roller 22. At this time, the operator starts the cigarette machine, and the paper feeding roller 22 conveys the tipping paper to the subsequent process. During this process, the anti-deviation rings 23 continuously form a physical block on the edge of the tipping paper, preventing the tipping paper from shifting to both sides from the paper feeding source. Then, after the tipping paper is output from the paper feeding roller 22, it enters between the three sets of limit rollers 32. The three sets of limit rollers 32 form The multi-node guiding path drives the limiting roller 32 to rotate synchronously during the feeding of the tipping paper. This corrects slight deviations remaining at the paper feeding end, further regularizes the feeding trajectory, and prevents the tipping paper from shifting during long-distance feeding. Subsequently, during the feeding process, the return spring 34 on the limiting roller 32 continuously pushes the contact ring 36 to keep it close to the edge of the tipping paper due to its own elastic tension. The contact ring 36 can move flexibly along the axial direction of the limiting roller 32 to ensure constant contact with the tipping paper. If the tipping paper shifts, it will squeeze the contact ring 36 on the corresponding side. The contact ring 36 transmits the pressure to the return spring 34, which in turn acts on the pressure sensor 35 on the fixed ring 33. The pressure sensor 35 converts the mechanical signal into an electrical signal and transmits it to the PLC controller 37 in real time. Finally, the PLC controller 37 judges the degree of deviation through a preset program. If the deviation exceeds the threshold, it immediately triggers the buzzer alarm 38, which emits a high-decibel warning sound to quickly remind the operator to intervene in a noisy workshop environment and avoid the generation of batches of defective products.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
