Description

Technical Field

[0001] The utility model relates to the technical field of YB55 packaging machines, in particular to an end soldering iron component of a YB55 packaging machine. Background Art

[0002] like Figure 1 As shown, the end soldering iron assembly of the YB55 packaging machine is mainly composed of a positioning block 1 and an end soldering iron 2, wherein the positioning block 1 plays a role in positioning and guiding the cigarette package when the equipment is operating normally, and the end soldering iron 2 is used to seal and beautify the folded transparent paper at the top and bottom of the cigarette package.

[0003] At present, the positioning block 1 is fixed and cannot be adjusted forward and backward to change the distance between the front and rear blocks. When the cigarette pack 4 is lifted up by the lifter, the cigarette pack cannot be quickly positioned, and the positioning block 1 does not exert a firm pressure on the cigarette pack 4 with the folded transparent paper, which causes the folded transparent paper to be easily loosened, and the rear end surface of the hot seal is uneven. After the positioning block 1 positions the cigarette pack 4, the pack pusher rod 3 pushes the cigarette pack 4 toward the end soldering iron 2. In the process of pushing the cigarette pack 4, the positioning block 1 also plays a guiding role, enabling the cigarette pack 4 to smoothly enter the soldering iron heat sealing channel.

[0004] The end soldering iron 2 is controlled to open and close by a cam, and the end soldering iron 2 is fixedly mounted on the soldering iron support 21. When the front package pushing rod 3 pushes the cigarette package 4 into the soldering iron heat sealing channel and stops, the end soldering iron 2 starts to heat seal the cigarette package 4. During normal operation, it is often found that the end face of the cigarette package 4 is not firmly sealed, and the end of the cigarette package 4 is not sealed flat, which leads to quality defects such as substandard sealing of the small box. In the process of product sampling, quality defects such as wrinkles on the cigarettes inside the small box are sometimes found. The above product quality problems are generally caused by the soldering iron position being adjusted too loose or too tight. When the end soldering iron 2 is too loose, the end face of the cigarette package 4 is not firmly sealed, the end of the cigarette package 4 is not sealed flat, and the sealing of the small box does not meet the standard. When the end soldering iron 2 is adjusted too tight, the pressure on the end face of the cigarette package 4 will increase, which will cause quality defects such as wrinkles on the cigarettes inside the small box.

[0005] Therefore, it is necessary to improve the end soldering iron assembly of the YB55 packaging machine to improve the sealing quality of cigarette packages. Utility Model Content

[0006] In view of the above problems, the utility model provides an end soldering iron assembly of a YB55 packaging machine, which changes the positioning block and the end soldering iron into an elastic structure, thereby improving the stability of the cigarette package lifting positioning guide and the heat sealing quality of the transparent paper end surface.

[0007] Specifically, the utility model provides an end soldering iron assembly of a YB55 packaging machine, comprising: an end soldering iron and a positioning block, wherein the end soldering iron is mounted on a soldering iron support, a side of the positioning block close to the cigarette pack is provided with a flexible side plate, and the flexible side plate is configured as an elastic structure that moves in a direction close to or away from the positioning block;

[0008] A first screw is provided between the end soldering iron and the soldering iron support. The first screw passes through the soldering iron support and is fixedly connected to the end soldering iron. A first spring is provided on the first screw. The first spring is located between the end soldering iron and the soldering iron support so that the end soldering iron can move in a direction close to or away from the soldering iron support.

[0009] Furthermore, a second screw is provided between the flexible side plate and the positioning block, and the second screw is fixedly connected to the flexible side plate after passing through the positioning block. A second spring is provided on the second screw, and the second spring is located between the flexible side plate and the positioning block.

[0010] Furthermore, at least two waist-shaped holes are provided at one end of the positioning block connected to the frame, and the waist-shaped holes are used to adjust the distance between the two positioning blocks.

[0011] Furthermore, the length of the positioning block is 11.5 cm, and the length of the end soldering iron is 10.5 cm.

[0012] Working principle:

[0013] When the lifter lifts the cigarette pack 4 to the positioning block 1, under the action of the rebound force of the second spring 12, the flexible side plate 11 exerts a certain squeezing force on the end of the cigarette pack 4, which has a braking effect on the cigarette pack 4. The squeezing force can also remove the air bubbles in the folded part of the transparent paper, making the rear surface more firm and smooth after hot sealing, thereby improving the sealing index.

[0014] After the cigarette pack 4 stops steadily, the pack pushing rod 3 pushes the cigarette pack 4 into the soldering iron heat sealing channel, and when the end soldering iron 2 is snapped together (that is, when the soldering iron support 21 drives the end soldering iron to move toward the cigarette pack), the end soldering iron 2 will contact the cigarette pack 4 in advance, and then compress the first spring 22; when the soldering iron support 21 moves into place (that is, when it is snapped together to the end point), the end soldering iron 2 will fit the cigarette pack more closely due to the small deformation of the first spring 22; when the soldering iron support 21 is to be retracted, the second spring 12 still has a reset time. The superposition of these two times during the arranging process and the retracting process will increase the heat-sealing time of the end soldering iron 2. At this time, the temperature of the soldering iron can be lowered. By lowering the soldering iron temperature and increasing the heat-sealing time, the heat-sealing quality of the end face of the cigarette pack 4 can be greatly improved.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] (1) The utility model provides a YB55 packaging machine end soldering iron assembly, and the design of the flexible side plate can brake the cigarette pack lifting, improve the stability of the positioning guide, and at the same time can remove the air bubbles in the folded part of the transparent paper, eliminating the quality problem of wrinkles on the top of the cigarette pack.

[0017] (2) The end soldering iron adopts an elastic design, which increases the contact time between the end soldering iron and the cigarette pack, can better achieve heat sealing of the end surface of the cigarette pack, and improve the quality of heat sealing. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The present invention is further described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0028] Example 1

[0029] like Figure 2 As shown, this embodiment provides an end soldering iron assembly of a YB55 packaging machine, which improves the original positioning block 1 and the end soldering iron 2 to solve the quality problems of top wrinkles, loose seals, uneven seals, wrinkles on cigarettes inside the small box, etc. when hot-sealing transparent paper.

[0030] Specifically, the end soldering iron assembly of the YB55 packaging machine includes: an end soldering iron 2 and a positioning block 1, such as Figure 3 As shown, the positioning block 1 is provided with two waist-shaped holes 14, and two fixing bolts are respectively passed through the two waist-shaped holes 14 and connected to the frame, which are used to roughly adjust the distance between the two positioning blocks 1 to ensure that the two positioning blocks 1 can play a good positioning and guiding role for the cigarette packs lifted up by the lifter. At the same time, by tightening with two fixing bolts, the rotation problem of the positioning block 1 itself can be effectively prevented, thereby ensuring the parallelism of the positioning block 1 and the end face of the cigarette pack 4.

[0031] A flexible side plate 11 is provided on the side of the positioning block 1 close to the cigarette pack 4. The positioning block 1 is provided with a plurality of through holes. A plurality of second screws 13 pass through the plurality of through holes and are threadedly connected with the back of the flexible side plate 11. Figure 5 As shown, the end of the second screw 13 away from the flexible side plate 11 is limited by the nut 5, and the second spring 12 is sleeved on the second screw 13. One end of the second spring 12 abuts against the flexible side plate 11, and the other end abuts against the positioning block 1. Specifically, when the positioning block 1 is installed, the position is first roughly adjusted through the waist-shaped hole 14. After the rough adjustment is completed, the position of the flexible side plate 11 is finely adjusted by adjusting the position of the second screw 13 and the nut 5 thereon, that is, the position of the flexible side plate 11 is finely adjusted by adjusting the length of the second screw 13 between the flexible side plate 11 and the positioning block 1. Figure 4 As shown, after the flexible side plate 11 is adjusted to a suitable position, when the cigarette pack 4 is lifted up by the lifter, its two ends are against the flexible side plates 11. Under the action of the rebound force of the second spring 12, the flexible side plates 11 are pressed toward the cigarette pack 4 to brake the cigarette pack. At the same time, the squeezing force can remove the air bubbles in the folded part of the transparent paper, thereby solving the problem of wrinkles on the top of the cigarette pack.

[0032] Furthermore, if Figure 1 As shown, the pack push rod 3 pushes the cigarette pack directly to the hot sealing station, and the front section of the original end soldering iron 2 cannot play a role in hot sealing. When the cigarette pack 4 with folded transparent paper passes through the front section of the end soldering iron 2 without heat sealing effect, the end soldering iron 2 is in an open state, and the folded transparent paper is easy to spread out. When the spread transparent paper passes through the next hot sealing process, it is easy to produce end wrinkles, loose hot sealing and other quality defects. Therefore, the overall length of the positioning block 1 is increased from 6.5cm to 11.5cm, and the length of the end soldering iron 2 is reduced to 10.5cm, so that its guiding distance to the cigarette pack is increased to the farthest end of the travel of the pack push rod 3, so that the cigarette pack 4 is subjected to the pressing force of the flexible side plate 11 before moving to the hot sealing station, thereby avoiding the problem that the folded transparent paper is easy to spread out before the cigarette pack 4 enters the hot sealing station, and improving the flatness and firmness of the hot sealing of the transparent paper.

[0033] The end soldering iron 2 is mounted on a soldering iron support 21 and opens and closes with the movement of the soldering iron support 21. Figure 6-7 As shown, a through hole is provided on the soldering iron support 21, and a first screw 23 is fixedly connected with the end soldering iron 2 after passing through the through hole. A first spring 22 is provided on the first screw 23, and the first spring 22 is located between the end soldering iron 2 and the soldering iron support 21, with one end against the end soldering iron 2 and the other end against the soldering iron support 21, so that the end soldering iron 2 can move in a direction close to or away from the soldering iron support 21. Under the action of the first spring 22, the end soldering iron 2 can provide a stable pressure on the cigarette pack 4, thereby avoiding the problem of loose sealing due to the end soldering iron 2 not being properly arranged and wrinkles on the cigarettes inside the small box due to too much arrangement of the end soldering iron 2. At the same time, when the cigarette pack 4 is pushed into the hot-sealing station by the pack pushing rod 3, the end soldering iron 2 is synchronously snapped together, and the end soldering iron 2 will contact the cigarette pack 4 in advance, and then compress the first spring 22; when the soldering iron support 21 moves into place (that is, when it is snapped together to the end point), the end soldering iron 2 will fit the cigarette pack 4 more closely due to the small deformation of the first spring 22; when the soldering iron support 21 is to be retracted, the second spring 22 still has a reset time. The superposition of these two times, the arrangement process and the retraction process, will increase the hot-sealing time of the end soldering iron. At this time, the temperature of the end soldering iron 2 can be lowered. By lowering the temperature of the end soldering iron 2 and increasing the hot-sealing time, the hot-sealing quality of the end face of the cigarette pack 4 can be greatly improved.

For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
