Description

Technical Field

[0001] This utility model relates to a pressing device to prevent irregularly shaped cigarettes from rebounding during the wrapping and sealing process, and belongs to the field of cigarette sorting and packaging technology. Background Technology

[0002] In cigarette pack sorting, it is often necessary to wrap and seal the cigarette packs. Existing literature (CN209441712U) discloses a wrapping and sealing device for irregularly shaped cigarette packs, which includes a sorting mechanism, a wrapping mechanism, a sealing and cutting mechanism, a heat shrinking mechanism, and a conveying mechanism. The sealing and cutting mechanism includes an upper sealing knife, a lower sealing knife, and a pressing mechanism. The upper sealing knife is used for partial sealing, and the upper and lower sealing knives are used for full sealing when they act simultaneously. However, the applicant has found in actual production that, due to the varying shapes and sizes of irregularly shaped cigarette packs, after automatic stacking, these packs naturally form uneven stacks. Because the pressing mechanism for wrapping and sealing irregularly shaped cigarettes is a rectangular flat plate, it can only press down on the highest point of the stack during the wrapping and sealing process. The remaining irregularly shaped cigarettes, without vertical force, are bounced back under the sealing and cutting knife, causing damage to the cigarettes during machine sealing. Utility Model Content

[0003] Based on the above, this utility model provides a pressing device to prevent irregularly shaped cigarettes from rebounding during the wrapping and sealing process, thereby overcoming the shortcomings of the prior art.

[0004] The technical solution of this utility model is: a pressing device to prevent irregularly shaped cigarettes from rebounding during the wrapping and sealing process, comprising: support; A drive cylinder is mounted on the bracket; The pressing plate includes an upper plate, pressing rods, a lower plate, and a spring. The upper end face of the upper plate is connected to the end of the telescopic rod of the driving cylinder. A plurality of pressing rods are vertically movably mounted on the upper plate. A plurality of lower plates are spaced apart along the length of the upper plate and are installed at the bottom of the pressing rods. The spring is mounted on the pressing rods and is located between the lower plates and the upper plates.

[0005] In one example, each of the lower plates has a pressing rod at both the front and rear ends, and the tops of the two pressing rods extend upward from the upper plate and are connected by a fixing plate.

[0006] In one example, an adjusting screw hole is provided on the upper plate at the position corresponding to the pressing rod, an adjusting screw tube is installed in the adjusting screw hole, a base plate is provided at the bottom of the adjusting screw tube, the pressing rod passes through the adjusting screw tube and the base plate, and the spring is installed between the base plate and the lower plate.

[0007] In one example, a guiding mechanism is also included, which includes a guide rod and a guide cylinder. The guide rod is located on both sides of the drive cylinder, and the guide cylinder is mounted on the bracket. The guide rod is movably fitted inside the guide cylinder, and the bottom of the guide rod is connected to the upper end face of the upper plate.

[0008] The beneficial effects of this invention are as follows: By setting multiple lower plates below the upper plate, and with these lower plates forming a flexible mechanism through pressing rods and springs, the existing single rectangular flat lower plate is transformed into multiple more flexible lower plates. This increases the vertical force-bearing area of ​​the irregularly shaped cigarettes during the wrapping and sealing process, effectively preventing the cigarettes from rebounding during wrapping and sealing, and reducing cigarette damage. Furthermore, the adjusting screws installed on the upper plate allow for adjustment of the height of the lower plates at various points, thus achieving uniform downward pressure at all locations and ensuring relatively consistent pressure across the stack of irregularly shaped cigarettes.

[0010] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0011] Please see Figures 1 to 4This embodiment provides a pressing device to prevent irregularly shaped cigarettes from rebounding during the wrapping and sealing process. The device includes a support 1, a drive cylinder 2, and a pressing plate 3. The drive cylinder 2 is mounted on the support 1. The pressing plate 3 includes an upper plate 31, pressing rods 32, a lower plate 33, and springs 34. The upper plate 31 is strip-shaped and horizontally arranged. The upper end face of the upper plate 31 is connected to the end of the telescopic rod of the drive cylinder 2. The drive cylinder 2 can drive the upper plate 31 to move up and down. Multiple pressing rods 32 are vertically movably mounted on the upper plate 31. Multiple lower plates 33 are spaced apart along the length of the upper plate 31, and the lower plates 33 are fixedly mounted on the bottom of the pressing rods 32. Springs 34 are fitted onto each pressing rod 32, and the springs 34 are located between the lower plates 33 and the upper plates 31.

[0012] By setting multiple lower plates 33 below the upper plate 31, and the lower plates 33 are installed to form a flexible mechanism by pressing rods 32 and springs 34, the lower plate 33 of the past rectangular flat plate is transformed into multiple lower plates 33 with higher flexibility. Compared with the prior art, the present invention increases the vertical force area of ​​irregular cigarettes during the wrapping and sealing process, effectively preventing the irregular cigarettes from rebounding during the wrapping and sealing process and reducing the occurrence of cigarette damage.

[0013] To ensure even force distribution, each lower plate 33 is equipped with a pressing rod 32 at both ends. The tops of the two pressing rods 32 extend upwards from the upper plate 31 and are connected together by a fixing plate 35. Thus, when pressed down, the two pressing rods 32 and the spring 34 ensure that the front and rear ends of the lower plate 33 are pressed down smoothly.

[0014] To facilitate adjustment of the position of the lower plate 33, an adjusting screw hole 36 is provided on the upper plate 31 at the position corresponding to the pressing rod 32. An adjusting screw tube 37 is installed in the adjusting screw hole 36, and the outer wall of the adjusting screw tube 37 has a corresponding thread, so the adjusting screw tube 37 can be rotated within the adjusting screw hole 36 to adjust its position. A base plate 38 is installed at the bottom of the adjusting screw tube 37, and the pressing rod 32 passes through the adjusting screw tube 37 and the base plate 38. A spring 34 is installed between the base plate 38 and the lower plate 33, so the position of the adjusting screw tube 37 can be adjusted as needed, thereby changing the height position of the lower plate 33. In production, the middle part of the irregularly shaped tobacco stack located below the pressing plate 3 is generally higher, while the two sides are lower. The lower plate 33 in the middle position can be adjusted by adjusting the adjusting screw tube 37 to make its bottom position higher, and the lower plate 33 in the two side positions can be adjusted by adjusting the adjusting screw tube 37 to make its bottom position lower, so as to achieve uniform downward pressure at all positions and ensure that the pressure on all parts of the irregularly shaped tobacco stack is relatively consistent.

[0015] For ease of operation, this device also includes a guide mechanism 4, which comprises guide rods 41 and guide cylinders 42. The two guide rods 41 are located on both sides of the drive cylinder 2, and the guide cylinders 42 are mounted on the bracket 1. The guide rods 41 are movably fitted inside the guide cylinders 42, and the bottom of the guide rods 41 is connected to the upper end face of the upper plate 31. The guide mechanism 4 ensures that both sides of the upper plate 31 are pressed down smoothly.

[0016] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
