Description

Technical Field

[0001] The utility model relates to a transparent paper tightening component, in particular to an improved transparent paper tightening component of a YB55 packaging machine, belonging to the technical field of cigarette manufacturing. Background Art

[0002] As we all know, the transparent paper tensioning component of the YB55 packaging machine plays the role of tensioning and braking the transparent paper tape when the equipment is operating normally.

[0003] The hinge of the existing transparent paper tightening arm is a nylon sleeve that fits the shaft with a clearance fit. Therefore, dust and moist air in the environment can easily enter this area during long-term operation (according to the "Cigarette Process Specifications", the indoor ambient temperature of the cigarette packaging production workshop should be 22.0℃~27.0℃±2.0℃, and the relative humidity should be 60.0%±5.0%). The shaft at the hinge is prone to rust and wear. When the dust and rust reach a certain amount, the hinge will become stuck, the movement will be inflexible, and the braking will be unstable, which will affect the tension of the transparent paper. During operation, the transparent paper tape will be loose and tight. If it is too loose, the equipment will report a "transparent paper broken" fault. If it is too tight, it will cause excessive traction on the transparent paper, resulting in deformation of the transparent paper tape and poor wrapping of the cigarette package.

[0004] During the production process, problems with the elastic edge of transparent paper can arise. This occurs when the inside and outside of the transparent paper strips are inconsistently tight. Excessive tension can lead to unstable paper conveying, resulting in conveyor blockages, poorly wrapped cigarettes, and skewed conveying, leading to misaligned puller threads and other quality issues. When there are too many defective cigarette packs, the detector cannot completely remove them all. These poorly wrapped packs then enter downstream machines, causing blockages or even being directly released to the market, disrupting product feedback and negatively impacting the company's image. Frequent paper jams can cause pack congestion during conveying, leading to equipment downtime and numerous semi-finished cigarette packs being crushed and discarded. This wastes the corresponding label paper and aluminum foil packs, resulting in significant waste of label paper, aluminum foil, and cigarettes. In summary, failures in the transparent paper tensioning assembly can lead to product quality defects, waste of raw materials and cigarettes, and equipment downtime, significantly impacting work efficiency.

[0005] Therefore, how to provide an improved transparent paper tightening component for the YB55 packaging machine has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0033] In the utility model, the first adjusting member (4) is a hexagon socket bolt, and the length of the first adjusting member (4) is greater than or equal to the thickness of the rocker plate (11) plus the thickness of the end of the connecting block (22).

[0036] Preferably, the invention further comprises a brake assembly (7), wherein the brake assembly (7) comprises: a brake seat (71) connected to the mounting shaft via a bearing (711);

[0037] A push plate (72), one end of which is connected to the upper portion of the brake seat (71), and the other end of which is cooperatively connected to the eccentric bearing (61);

[0038] A first tension spring (73), one end of the first tension spring (73) is connected to the brake seat (71), and the other end of the first tension spring (73) is connected to a first tension spring connecting seat connected to the YB55 packaging machine;

[0039] A second tension spring (74), one end of the second tension spring (74) is connected to a second tension spring connecting seat fixed on the YB55 packaging machine, and the other end of the second tension spring (74) is connected to the lower part of the brake pressure plate (6); wherein, one end surface of the brake seat (71) is connected to the transparent drive paper disk (8) through a brake pad.

[0040] The working principle is as follows: the above-mentioned improved YB55 packaging machine transparent paper tightening assembly, before working, first, needs to assemble the rocker frame (1), and install the paper guide roller retaining spring (14), the paper guide roller connecting bearing (13), and the paper guide roller retaining spring (14) at the two ends of the paper guide roller (12) in sequence, and the two paper guide roller retaining springs (14) are respectively clamped in the respective paper guide roller retaining spring grooves to limit the paper guide roller connecting bearing (13); wherein, the paper guide roller retaining spring (14) installed later is clamped and fixed in the paper guide roller mounting hole of the rocker plate (11). Then, the first adjusting member (4) is used to pass through the rocker frame through hole (101) on the rocker frame (1) and screwed into the first adjusting threaded hole corresponding to the connecting block (22) in a clockwise direction, and the second adjusting member (5) is used to screw in from the second adjusting threaded hole of the connecting block (22) and tighten clockwise. At this time, the second adjusting member (5) can only be screwed in partially and cannot be screwed in completely. Then, the retaining spring (32) and the connecting bearing (31) are successively inserted into the fixed shaft (9), the connecting sleeve (21) is passed through the fixed shaft (9), and the connecting bearing (31) and the retaining spring (32) are successively installed, wherein the connecting bearing (31) is located at both ends of the connecting sleeve (21) and is fixed by the retaining spring (31). Finally, the rocker arm connecting seat (2) is connected to the brake pressure plate (6) through the fixed shaft (9), and an eccentric bearing (61) is installed at one end of the brake pressure plate (6), and the other end is connected to the second tension spring (74). The eccentric bearing (61) is fitted with the push plate (72) at one end of the brake assembly (7), and the other end of the brake assembly (7) is provided with a brake seat (71). The brake seat (71) is tightened and fitted to the lower side of the driving paper disk (8) by the first tension spring (73), wherein the brake seat (71) and the push plate (72) are connected by a bearing (711) and fixed to the device body (10).

[0041] During operation, the transparent paper is pulled out from the driving paper tray (8), passes through the paper guide roller (12) and the fixed column, and is transported in an "S-shaped" manner;

[0042] During normal operation, the transparent paper provides a pulling force to the rocker frame (1). Under the action of the pulling force, the connecting sleeve (21) drives the rocker frame (1) to rotate counterclockwise around the fixed shaft (9) through the connecting bearing (31), so that the rocker frame (1) tilts forward, and the second tension spring (73) connected to one end of the brake pressure plate (6) is stretched. The eccentric bearing (61) at the other end of the brake pressure plate (6) provides a thrust to the push plate (72). The first tension spring (73) is stretched, so that the brake seat (71) of the brake assembly (7) is separated from the driving paper disk (8), so that the transparent paper can be continuously transmitted.

[0043] When the problem of loose or tight edges of the transparent paper occurs, first loosen the first adjusting member (4) a little bit, and then tighten the second adjusting member (5). At this time, because the length of the second adjusting member (5) is greater than the thickness of the end of the connecting block (22), a gap appears between the rocker arm frame (1) and the rocker arm connecting seat (2). By adjusting the difference in the gap between the two connecting blocks (22) and the rocker arm frame (1), the loose or tight edges can be adjusted.

[0044] When the transparent paper breaks, the transparent paper no longer exerts a strong force on the rocker frame (1), and the second tension spring (74) provides a pulling force to make the rocker frame (1) rotate clockwise until it reaches a limit position (not shown in the figure). At this time, the eccentric bearing (61) at one end of the brake pressure plate (6) no longer provides a thrust to the push plate (72), and the first tension spring (73) drives the brake seat (71) to fit the drive paper tray (8), thereby braking and stopping the transmission of the transparent paper.

[0045] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0046] 1. The utility model has a simple structure, a simple construction, a novel and reasonable design, and the rocker plate adopts a rectangular steel design, which improves the rigidity of the connection with the rocker connecting seat and the paper guide roller, making the connection more stable and the service life longer;

[0047] 2. The paper guide roller of the utility model is replaced by a paper guide roller bearing and a paper guide roller retaining spring fixedly connected. The paper guide roller bearing is a self-aligning bearing. After long-term use, the original bearing may wear, rust or jam. After replacing it with a self-aligning bearing, the above-mentioned situation can be avoided, and the loose edge of the transparent paper can be prevented during the transmission process.

[0048] 3. The two ends of the rocker arm connecting seat of the utility model are connected to the fixed shaft through connecting bearings and retaining springs, which changes the original sliding friction into rolling friction, resulting in less loss and better sealing effect. Dust and moisture are not easy to enter the connection parts, which will not cause rust or jamming, thereby extending the service life.

[0049] 4. The length of the second adjusting member of the utility model is greater than the thickness of the end of the connecting block, so the first adjusting member and the second adjusting member can be matched to form a gap between the rocker arm frame and the rocker arm connecting seat, thereby adjusting the problem of looseness or tightness of the paper guide roller after long-term use;

[0050] 5. The through hole of the rocking frame of the utility model is an elongated hole, and the upper and lower height distances between the rocker frame and the rocker connecting seat can be slightly adjusted according to the use requirements, making the adjustment of the component more flexible and practical; at the same time, the design of the elongated hole can make the rocker frame move up or down a certain distance relative to the rocker connecting seat, which can play the role of tensioning the transparent paper, and can play the role of adjusting the tightness of the edge when the rocker plates on both sides are displaced differently.

It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other unless there is a conflict. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0072] Example 1

[0073] As the instruction manual Figure 1 To the instruction manual Figure 8 An improved transparent paper tightening assembly of the YB55 packaging machine shown includes:

[0074] The rocker frame 1 has a plurality of rocker frame through holes 101 symmetrically opened on both sides of one end of the rocker frame 1;

[0075] The rocker arm connecting seat 2 is rotatably mounted on the fixed shaft 9;

[0076] Connecting assembly 3, connecting assembly 3 is symmetrically connected to both ends of the rocker arm connecting seat 2;

[0077] The first adjusting members 4 are respectively passed through the rocking frame through holes 101 of the rocking frame 1 and are adjustably mounted on the corresponding ends of the rocking arm connecting seat 2;

[0078] The second adjusting member 5 is threadedly connected to both ends of the rocker arm connecting seat 2;

[0079] The first adjusting member 4 and the second adjusting member 5 cooperate with each other to adjust the distance between the rocker arm frame 1 and the rocker arm connecting seat 2 .

[0080] Furthermore, the rocker frame 1 includes:

[0081] The rocker plates 11 are arranged opposite to each other, and the other end of the rocker plates 11 is provided with a paper guide roller mounting hole;

[0082] The paper guide rollers 12 are rotatably connected to the paper guide roller mounting holes of the two rocker plates 11;

[0083] The paper guide roller locking assembly is connected to both ends of the paper guide roller 12 and is located in the paper guide roller mounting hole;

[0084] The total number of the rocking frame through holes 101 is four, and the rocking frame through holes 101 are respectively set through one end of the two rocker arm plates 11 .

[0085] In the present invention, the rocker plate 11 is a rectangular strip structure, which can make the fixation of the paper guide roller 12 more stable, and at the same time provide rigid support between the first adjusting member 4 and the connecting block 22, making the connection between the first adjusting member 4 and the connecting block 22 tighter and more stable.

[0086] Example 2

[0087] Further, such as Figure 3 As shown, the swing frame through hole 101 is an elongated hole;

[0088] Both ends of the paper guide roller mounting hole are provided with paper guide roller retaining spring grooves;

[0089] The paper guide roller locking assembly includes: a paper guide roller connecting bearing 13, the inner ring of the paper guide roller connecting bearing 13 is sleeved on the end of the paper guide roller 12, and the outer ring of the paper guide roller connecting bearing 13 is connected to the paper guide roller mounting hole;

[0090] The paper guide roller retaining springs 14 are respectively engaged in the retaining spring grooves of the paper guide rollers and are used to limit the paper guide roller connection bearings 13 .

[0091] Furthermore, the rocker arm connecting seat 2 includes:

[0092] Connecting sleeve 21, both ends of the connecting sleeve 21 are provided with connecting bearing mounting holes and retaining ring grooves from the inside to the outside;

[0093] The connecting blocks 22 are symmetrically connected to both ends of the connecting sleeve 21 .

[0094] Furthermore, second adjustment threaded holes adapted to connect with the second adjustment member 5 are formed through both ends of the connecting block 22 ; first adjustment threaded holes adapted to connect with the first adjustment member 4 are formed through both ends of the connecting block 22 within the two second adjustment threaded holes.

[0095] Furthermore, the connection component 3 includes:

[0096] Connecting bearings 31, the connecting bearings 31 are respectively installed in the connecting bearing mounting holes of the connecting sleeve 21;

[0097] The retaining springs 32 are respectively installed in the retaining spring grooves of the connecting sleeve 21 .

[0098] In the present invention, the design of the long hole 101 of the rocking frame can make the first adjusting member 4 easier to install, without the need for repeated positioning and alignment, and the design of the long hole can make the rocker frame 1 move upward or downward a certain distance relative to the rocker connecting seat 2, which can play the role of tensioning the transparent paper. When the rocker plates 11 on both sides are displaced differently, it can play the role of adjusting the tightness of the edge.

[0099] In this utility model, the paper guide roller connecting bearing 13 is a core-aligning bearing. Conventional bearings can wear and jam over time, easily causing the loose edge and paper guide roller 12 to jam. Using a core-aligning bearing prevents this. The use of the connecting bearing 31 replaces sliding friction with rolling friction, reducing wear. Furthermore, the bearing's sealing properties prevent dust and moisture from entering the connection, preventing rust and jamming, and extending service life.

[0100] Example 3

[0101] This embodiment 3 is the same as embodiment 1 and embodiment 2, with the only difference being that the first adjusting member 4 and the second adjusting member 5 are anti-slip bolts, or their threads are covered with a portion of anti-slip thread glue.

[0102] Furthermore, the first adjusting member 4 and the second adjusting member 5 are both bolts.

[0103] In the present invention, the first adjusting member 4 is a hexagon socket bolt, and the length of the first adjusting member 4 is greater than or equal to the thickness of the rocker plate 11 plus the thickness of the end of the connecting block 22 .

[0104] Further, such as Figure 4 As shown, the first adjusting member 4 and the second adjusting member 5 are both hexagon socket bolts; the length of the second adjusting member 5 is greater than the thickness of the end of the connecting block 22.

[0105] In the present invention, the adjustment of the elastic edge is carried out by cooperating with the first adjusting member 4 and the second adjusting member 5. When the elastic edge occurs, the first adjusting member 4 is partially loosened and the second adjusting member 5 is tightened. Because the length of the second adjusting member 5 is greater than the thickness of the end of the connecting block 22, when the second adjusting member is tightened, a gap will be formed between the rocker frame 1 and the connecting block 22. By adjusting the gap between the rocker frame 1 and the connecting block 22 at both ends of the rocker connecting seat 2, the problem of the elastic edge of the transparent paper is adjusted.

[0106] In the present invention, when there is no loose edge, the second adjusting member 5 is in a state of not being fully tightened; when there is a loose edge, the first adjusting member 4 is in a state of not being fully tightened after adjustment.

[0107] Therefore, in order to prevent the first adjusting member 4 and the second adjusting member 5 from loosening and falling off due to vibration during the transmission of the transparent paper, it is necessary to use an anti-loosening bolt or cover the thread thereof with a portion of anti-loosening thread glue.

[0108] Example 4

[0109] This embodiment 4 is the same as embodiments 1-3, with the only difference being that the bearing 711 is a center-aligning bearing.

[0110] Further, such as Figure 7-8 As shown, it also includes a brake pressure plate 6, which is connected to one end of the connecting sleeve 21, and the upper part of the brake pressure plate 6 is rotatably connected to an eccentric bearing 61.

[0111] Furthermore, a brake assembly 7 is included, and the brake assembly 7 includes: a brake seat 71 connected to the mounting shaft through a bearing 711;

[0112] A push plate 72, one end of which is connected to the upper portion of the brake seat 71, and the other end of which is cooperatively connected to the eccentric bearing 61;

[0113] A first tension spring 73, one end of the first tension spring 73 is connected to the brake seat 71, and the other end of the first tension spring 73 is connected to the first tension spring connecting seat connected to the YB55 packaging machine;

[0114] A second tension spring 74, one end of the second tension spring 74 is connected to a second tension spring connecting seat fixed on the YB55 packaging machine, and the other end of the second tension spring 74 is connected to the lower portion of the brake pressure plate 6;

[0115] One end surface of the brake seat 71 is connected to the driving paper tray 8 through a brake pad.

[0116] In the present invention, the brake assembly 7 may become rusted and stuck or worn due to the external environment or long time of use, resulting in the brake seat 71 and the drive paper plate 8 not being able to fit and separate in time. The core-adjusting bearing is used to solve the above problem and reduce the occurrence of problems caused by rust, jamming or wear.

[0117] In summary, the specific implementation of the present invention is:

[0118] Before operation, the improved transparent paper tightening assembly for the YB55 packaging machine described above must first be assembled with the rocker frame 1. The paper guide roller retaining spring 14, the paper guide roller connecting bearing 13, and the paper guide roller retaining spring 14 are sequentially installed at the two ends of the paper guide roller 12. The two paper guide roller retaining springs 14 are respectively engaged in the respective paper guide roller retaining spring grooves to limit the position of the paper guide roller connecting bearing 13. The latter paper guide roller retaining spring 14 is then clamped and fixed in the paper guide roller mounting hole of the rocker plate 11. The first adjusting member 4 is then threaded clockwise through the rocker frame through-hole 101 on the rocker frame 1 into the corresponding first adjusting threaded hole of the connecting block 22. The second adjusting member 5 is then threaded in clockwise from the second adjusting threaded hole of the connecting block 22 and tightened. At this point, the second adjusting member 5 can only be partially screwed in, not completely. Next, the retaining spring 32 and the connecting bearing 31 are inserted onto the fixed shaft 9 in sequence. The connecting sleeve 21 is passed through the fixed shaft 9, and the connecting bearing 31 and retaining spring 32 are installed in sequence. The connecting bearing 31 is located at both ends of the connecting sleeve and is secured by the retaining spring 31. Finally, the rocker arm connecting base 2 is connected to the brake pressure plate 6 via the fixed shaft 9. An eccentric bearing 61 is mounted on one end of the brake pressure plate 6, and the other end is connected to a second tension spring 74. The eccentric bearing 61 is in contact with the push plate 72 at one end of the brake assembly 7. The other end of the brake assembly 7 is equipped with a brake seat 71, which is tightened against the underside of the drive paper tray 8 by a first tension spring 73. The brake seat 71 and the push plate 72 are connected by a bearing 711 and fixed to the device body 10.

[0119] During operation, the transparent paper is pulled out from the driving paper tray 8, passes through the paper guide roller 12 and the fixed column, and is transported in an "S-shaped" manner;

[0120] During normal operation, the transparent paper provides a pulling force on the rocker frame 1. Under the action of the pulling force, the connecting sleeve 21 drives the rocker frame 1 to rotate counterclockwise around the fixed axis 9 through the connecting bearing 31, causing the rocker frame 1 to tilt forward. The second tension spring 73 connected to one end of the brake pressure plate 6 is stretched, and the eccentric bearing 61 at the other end of the brake pressure plate 6 provides a thrust to the push plate 72. The first tension spring 73 is stretched, separating the brake seat 71 of the brake assembly 7 from the driving paper tray 8, so that the transparent paper can be continuously transported.

[0121] When the transparent paper has a problem of loose edges, first loosen the first adjusting piece 4 a little, and then tighten the second adjusting piece 5. At this time, because the length of the second adjusting piece 5 is greater than the thickness of the end of the connecting block 22, a gap will appear between the rocker arm frame 1 and the rocker arm connecting seat 2. By adjusting the difference in the gap between the two connecting blocks 22 and the rocker arm frame 1, the loose edges can be adjusted.

[0122] When the transparent paper breaks, the transparent paper no longer has a strong effect on the rocker frame 1. The second tension spring 74 provides a pulling force to make the rocker frame 1 rotate clockwise until the limit position is not marked in the figure. At this time, the eccentric bearing 61 at one end of the brake pressure plate 6 no longer provides thrust to the push plate 72. The first tension spring 73 drives the brake seat 71 to fit against the drive paper tray 8, braking the transparent paper transmission to stop.

[0123] In the present invention, the connection mentioned is a fixed connection or a detachable connection, wherein the fixed connection is a welding connection or directly processed into an integrally formed structure, and the detachable connection is an internal and external thread connection or a snap-fit ​​connection or a plug-in structure connection.

[0124] In summary, the advantages of the present invention in the specific implementation are:

[0125] 1. The utility model has a simple structure, a simple construction, a novel and reasonable design, and the rocker plate 11 adopts a rectangular steel design, which improves the rigidity of the connection with the rocker connecting seat 2 and the paper guide roller 12, making the connection more stable and the service life longer;

[0126] 2. The paper guide roller 12 of the present invention is replaced by a paper guide roller bearing 13 and a paper guide roller retaining spring 14, wherein the paper guide roller bearing 13 is a self-aligning bearing. After long-term use, the original bearing may wear, rust or jam. After replacing it with a self-aligning bearing, the above-mentioned situation can be avoided, and the loose edge of the transparent paper during the transmission process is prevented;

[0127] 3. The two ends of the rocker arm connecting seat 2 of the utility model are connected to the fixed shaft 9 through the connecting bearing 31 and the retaining spring 32, which changes the original sliding friction into rolling friction, resulting in less loss and better sealing effect. Dust and moisture are not easy to enter the connection part, which will not cause rust or jamming, thereby extending the service life.

[0128] 4. The length of the second adjusting member 5 of the utility model is greater than the thickness of the end of the connecting block 22. Therefore, the first adjusting member 4 and the second adjusting member 5 can be matched to form a gap between the rocker frame 1 and the rocker connecting seat 2, thereby adjusting the problem of looseness or tightness of the paper guide roller after long-term use;

[0129] 5. The through hole 101 of the rocking frame of the present invention is an elongated hole, and the upper and lower height distances between the rocker frame 1 and the rocker connecting seat 2 can be slightly adjusted according to usage requirements, making the adjustment of the component more flexible and practical; at the same time, the design of the elongated hole can make the rocker frame 1 move upward or downward relative to the rocker connecting seat 2 for a certain distance, which can play the role of tensioning the transparent paper, and when the rocker plates 11 on both sides are displaced differently, it can play the role of adjusting the tightness of the edge.

[0130] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and does not constitute any other limitation to the present invention. Any person skilled in the art may utilize the above-disclosed technical content to modify or remodel the present invention into equivalent embodiments. However, any simple modifications, equivalent variations, and modifications to the above embodiments that do not depart from the technical content of the present invention and are based on the technical essence of the present invention shall still fall within the scope of protection of the present invention.
