Abstract
Description
Technical Field
[0001] This utility model relates to the field of filter rod forming equipment, and more specifically, to a hollow filter rod wrinkle removal device. Background Technology
[0002] Traditional filter rod manufacturing involves unwinding and spreading a coiled fiber bundle, applying a plasticizer evenly to the spread bundle surface, and then feeding it to the filter rod forming section. The forming section wraps the fed fiber bundle with forming paper and rolls it into filter strips, which are then cut into individual filter rods and finally output by a conveyor. However, in the production of paperless hollow filter rods, due to the unique nature of its forming process, wrinkles are easily squeezed into the filter rod at the seams of the fabric belt during the wrapping and forming process. This affects the roundness, circumference, and appearance of the filter rod, further negatively impacting the filter rod lamination or cigarette rolling process.
[0003] Utility model patent CN204560942U discloses a device for eliminating indentations on filter rods. The device involves introducing the filter rod, after it has been formed into a fiber bundle, into a ceramic heating chamber. The heating chamber is a circular sleeve, which eliminates the indentations on the filter rod. Invention patent application CN 103300473 A discloses a heating ironing sleeve with a cylindrical cavity added to the output end of the fabric tape. This ironing sleeve is adapted to the circumference of the paperless filter rod. The heating chamber contains a steam storage chamber, and the steam in the steam storage chamber heats the heating ironing sleeve, thereby eliminating indentations on the filter rod. However, the devices disclosed in these two patent documents are complex in structure and cumbersome to operate. Furthermore, when the filter rod develops raised wrinkles due to compression, the wrinkles and the cavity exert impact force, affecting the quality of the filter rod and production. Therefore, there is a need for a simple, fast, convenient, and effective device for eliminating wrinkles on filter rods. Utility Model Content
[0004] To achieve a simple, fast, convenient and effective way to eliminate filter rod wrinkles, the technical solution adopted by this utility model is: a hollow filter rod wrinkle elimination device, which is installed on a forming plate. The forming plate has a filter rod forming channel, including a fixing mechanism connected to the forming plate. A smoothing block assembly is elastically arranged inside the fixing mechanism. The bottom of the smoothing block assembly passes through the fixing mechanism and extends into the filter rod forming channel. The smoothing block assembly is used to smooth out wrinkles in the hollow filter rod within the filter rod forming channel using elasticity.
[0005] Based on the above, the smoothing block assembly includes a smoothing block and a fixing plate for mounting the smoothing block. The top of the fixing plate is provided with a fixing bolt for connecting the fixing mechanism, and a spring is sleeved on the outside of the fixing bolt.
[0006] Based on the above, a transverse mounting hole is provided on the upper part of the fixing plate, and a transverse fixing screw passing through the transverse mounting hole is provided in the middle of the fixing mechanism, with the transverse mounting hole and the transverse fixing screw having a clearance fit. The horizontal fixing screw is used to limit the length of the smoothing block extending into the filter rod forming channel by restricting the vertical movement of the fixing plate.
[0007] Beneficial effects: Due to the large length and width of the fixing plate and the smoothing block, relying solely on the fixing cylinder for guidance would result in wobbling. Therefore, by setting a transverse fixing screw, the vertical movement of the fixing plate can be limited, thereby restricting the length of the smoothing block extending into the filter rod forming channel.
[0008] Based on the above, the fixing mechanism includes a fixing cylinder and a top cover plate. The bottom of the fixing cylinder is detachably connected to the forming plate by mounting screws. The top cover plate is set on the top of the fixing cylinder by connecting screws. The fixing plate and the smoothing block are movably arranged inside the fixing cylinder.
[0009] Based on the above, the bottom of the smoothing block is flat, and the width of the smoothing block is smaller than the width of the filter rod forming channel.
[0010] Based on the above, the center line of the smoothing block coincides with the center line of the filter rod forming channel.
[0011] Based on the above, the forming plate has at least two parallel filter rod forming channels, and each filter rod forming channel is provided with the fixing mechanism and the smoothing block assembly.
[0012] This utility model has substantial features and advancements compared to existing technologies. Specifically, the hollow filter rod wrinkle elimination device provided by this utility model analyzes the causes and processes of wrinkles generated during the filter rod forming process. It sets up a smoothing block assembly and a fixing mechanism on the filter rod forming channel to smooth the wrinkles using elastic pressure. This allows the smoothing block assembly to continuously smooth the wrinkles on the filter rod, effectively avoiding the impact of wrinkles on the filter rod and improving the efficiency of the filter rod production line.
[0013] Furthermore, by designing the smoothing block assembly as a smoothing block and a fixing plate, and by providing a transverse mounting hole on the fixing plate and a transverse fixing screw between the transverse mounting hole and the fixing cylinder, the transverse fixing screw can be used to limit the vertical movement of the fixing plate, thereby limiting the length of the smoothing block extending into the filter rod forming channel, thus increasing the stability of the smoothing block. Therefore, this hollow filter rod wrinkle removal device can achieve simple, fast, convenient, and effective removal of filter rod wrinkles. Attached Figure Description

[0020] The technical solution of this utility model will be further described in detail below through specific embodiments.
[0021] Example 1 This embodiment provides a device for eliminating wrinkles in hollow filter rods, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a filter rod forming channel 2 is formed and installed on a forming plate 1. The forming plate 1 includes a fixing mechanism 3 connected to the forming plate 1. A smoothing block assembly is elastically disposed inside the fixing mechanism 3. The bottom of the smoothing block assembly passes through the fixing mechanism 3 and extends into the filter rod forming channel 2. The smoothing block assembly is used to smooth out wrinkles in the hollow filter rod within the filter rod forming channel 2 using elastic force.
[0022] Specifically, such as Figure 1 and Figure 2As shown, the smoothing block assembly includes a smoothing block 15 and a fixing plate 16 for mounting the smoothing block 15. The top of the fixing plate 16 is provided with a fixing bolt 14 for connecting to the fixing mechanism 3, and a spring 18 is sleeved on the outside of the fixing bolt 14. That is, when the filter rod wrinkles come into contact with the smoothing block 15, the spring 18 ensures that they are always under a certain downward pressure, and also provides a buffering effect during the wrinkle removal process.
[0023] Specifically, the fixing mechanism 3 includes a fixing cylinder 9 and a top cover plate 12. The bottom of the fixing cylinder 9 is detachably connected to the forming plate 1 via mounting screws 10. The top cover plate 12 is mounted on the top of the fixing cylinder 9 via connecting screws 13. The fixing plate 16 and the smoothing block 15 are movably disposed within the fixing cylinder 9.
[0024] Example 2 This embodiment provides a hollow filter rod wrinkle removal device. The main difference from Embodiment 1 is that, in this embodiment, the upper part of the fixing plate 16 has a transverse assembly hole 17. The middle part of the fixing mechanism 3 is provided with a transverse fixing screw 11 passing through the transverse assembly hole 17. The transverse assembly hole 17 and the transverse fixing screw 11 are clearance-fitted. The transverse fixing screw 11 is used to limit the vertical movement range of the fixing plate 16, thereby limiting the length of the smoothing block 15 extending into the filter rod forming channel 2.
[0025] Example 3 This embodiment provides a hollow filter rod wrinkle removal device. The main difference from Embodiment 1 is that in this embodiment, the bottom of the smoothing block 15 is flat, and the width of the smoothing block 15 is smaller than the width of the filter rod forming channel 2. The center line of the smoothing block 15 coincides with the center line of the filter rod forming channel 2.
[0026] Example 4 This embodiment provides a hollow filter rod wrinkle removal device. The main difference from Embodiment 1 is that in this embodiment, at least two parallel filter rod forming channels 2 are provided in the forming plate 1, and each filter rod forming channel 2 is provided with the fixing mechanism 3 and the smoothing block assembly.
[0027] Among them, such as Figure 4 and Figure 5 As shown, the forming plate 1 is spliced with a forming and curing plate 4 and a high-pressure air cover plate 5, and the high-pressure air cover plate 5 is provided with a high-pressure air pipe 6. The forming plate 1 is provided with a first clearance hole 7 and a second clearance hole 8 respectively corresponding to the fixing mechanism 3.
[0028] Specifically, when using the hollow filter rod wrinkle removal device provided by this utility model to remove wrinkles from the hollow filter rod, the filter rod is transported to the filter rod forming channel by the filter rod conveyor belt. It is shaped by the high temperature and high pressure steam in the filter rod forming channel. During the shaping and conveying process, the bottom of the smoothing block 15 is pressed against the wrinkle of the filter rod, so that the wrinkles of the filter rod are removed before the smoke gun cools and shapes.
[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
