Description

Technical Field

[0001] The present invention relates to the technical field of cigarette manufacturing equipment, and particularly to a wire suction beam device. Background Art

[0002] When the YJ17 feeding and strip-forming unit is working, the air chamber is locked by a locking mechanism to form a negative pressure chamber. The negative pressure is provided by a high-pressure ventilator. There is a wire suction beam and a baffle at the lower part of the air chamber body to form a wire suction and forming groove. The negative pressure adsorbs and conveys the cut tobacco forward. Under the action of the wire suction beam, a cut tobacco bundle with a certain width is formed.

[0003] In the tobacco production industry, the wire suction beam device is a key equipment in the cigarette forming process, and its performance directly affects the quality and production efficiency of cigarettes. Refer to Figure 1 , the wire suction beam device in the prior art is usually composed of components such as a wire suction plate 100, and is mainly used for adsorbing and conveying cut tobacco to realize the forming of cigarettes.

[0004] However, the overall width of the existing wire suction beam device is 20 mm, but the width of the upper negative pressure channel is only 4.8 mm, and the width of the contact part between the bottom and the wire suction belt (the width of the wire suction and forming groove 200) is 7.4 mm. This device has certain technical defects. On the one hand, its structural design results in a small distance between the two wire suction plates 100, thus causing insufficient air intake. Insufficient air intake will affect the adsorption and conveying effect of cut tobacco, making the distribution of cut tobacco uneven during the forming process. On the other hand, the unreasonable structure of the upper-narrow and lower-wide negative pressure channel in the existing wire suction beam device causes the negative pressure to reach the wire suction belt below the wire suction beam device after passing through the upper part of the wire suction beam device. Due to the increase in width, it is easy to cause negative pressure loss in the shaping, which not only reduces the working efficiency of the wire suction beam device, but also leads to unstable cigarette weight, problems such as void heads in the quality of cigarettes, etc., seriously affecting the quality and production stability of cigarettes. With the continuous improvement of the quality requirements for cigarettes in the tobacco industry, there is an urgent need to improve the existing wire suction beam device to solve the above technical problems and meet the production requirements. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention develops a wire suction beam device, which realizes increasing the plate distance by using the "L"-shaped cross-section of the wire suction plate to increase the air intake, forming an upper-wide and lower-narrow negative pressure channel to reduce negative pressure loss, and combining magnetic bead guidance and strut stabilizing structure to achieve stable cigarette weight, reduce the problem of void heads and improve production stability.

[0006] The technical solution for the present invention to solve the technical problems is as follows: The present application provides a wire suction beam device, including two wire suction plates, as well as a pin shaft and magnetic beads; An installation opening is provided on the inner side of the wire suction plate, such that the cross-sections of the two wire suction plates are both "L"-shaped and are arranged in mirror symmetry; a notch is provided on the inner side of the bottom end of the wire suction plate, and the notches of the two wire suction plates are arranged opposite to each other to form a wire suction forming groove, and the two installation openings are arranged opposite to each other to form an installation groove; the groove width of the installation groove is greater than the groove width of the wire suction forming groove. A plurality of pin shafts holes are evenly provided on the wire suction plate, the magnetic beads are sleeved on the outer wall surface of the pin shaft, and both ends of the pin shaft are inserted into the corresponding pin shafts holes, and the magnetic beads are installed between the two wire suction plates through the pin shaft.

[0007] The wire suction beam device further includes a support column, and the support column is connected between the two wire suction plates.

[0008] As an improvement to the above solution, a plurality of support column holes are evenly provided on the wire suction plate, a support column sleeve corresponding to the position of the support column hole extends inwardly on the wire suction plate, and both ends of the support column are respectively inserted into the corresponding support column sleeves.

[0009] As an improvement to the above solution, a pin shaft sleeve corresponding to the position of the pin shaft hole extends inwardly on the wire suction plate, and both ends of the pin shaft are inserted into the corresponding pin shaft sleeves.

[0010] As an improvement to the above solution, the groove width of the installation groove is 15.2 mm, and the groove width of the wire suction forming groove is 7.4 mm.

[0011] Compared with the prior art, the above solution has the following advantages or beneficial effects: 1. Intake air and negative pressure optimization: The wire suction plate is provided with an installation opening with an "L"-shaped cross-section, increasing the distance between the wire suction plates, increasing the intake air volume when the total width remains unchanged, and forming a negative pressure channel that is wider at the top and narrower at the bottom, reducing negative pressure loss and stabilizing the adsorption pressure.

[0012] 2. Improve the quality of cigarette rods: Stable intake air and negative pressure ensure stable adsorption and transportation of cut tobacco, making the weight of cigarette rods stable, reducing the problem of empty heads, and improving the finished product quality.

[0013] 3. The structure and function are reliable: The magnetic beads assist in the formation of cut tobacco, and the support columns stabilize the position of the wire suction plate, ensuring the stability of the device structure, and each component cooperates to ensure the forming effect and working performance.

[0026] Referring to Figures 1-9 , this embodiment provides a wire suction beam device, including two wire suction plates 1, struts 2, pin shafts 3 and magnetic beads 4 which are mirror-image arranged.

[0027] The inner side of each wire suction plate 1 is recessed inward and downward to form an installation opening 11, so that the cross-section of the two wire suction plates 1 is in an "L" shape. A notch 12 is opened on the inner side of the bottom end of the wire suction plate 1. When the two wire suction plates 1 are arranged oppositely, the notches 12 of the two are opposite to form a wire suction forming groove 13, which is used for forming and guiding the cut tobacco. The two installation openings 11 are also arranged oppositely to form an installation groove 14 for installing the struts 2 and the magnetic beads 4. The groove width of the installation groove 14 is greater than the groove width of the wire suction forming groove 13, so as to form a negative pressure channel with a wider upper part and a narrower lower part, so as to avoid negative pressure loss caused by the negative pressure entering the lower part of the wire suction beam device from the upper part of the wire suction beam device.

[0028] A plurality of pin shaft holes and support post holes are equidistantly arranged on the wire suction plate 1, and a pin shaft sleeve 5 and a support post sleeve 6 are arranged to extend inwards on the wire suction plate 1. Among them, the pin shaft sleeve 5 corresponds to the position of the pin shaft hole, that is, the pin shaft sleeve 5 is a tubular structure extending inwards from the pin shaft hole, and the support post sleeve 6 corresponds to the position of the support post hole, that is, the support post sleeve 6 is a tubular structure extending inwards from the support post hole. The magnetic beads 4 are sleeved on the outer wall surface of the pin shaft 3, and both ends of the pin shaft 3 are inserted into the pin shaft sleeves 5 on two corresponding wire suction plates 1. Through this connection method, the magnetic beads 4 are stably installed between the two wire suction plates 1, and the magnetic beads 4 can play a certain role in adsorbing or guiding the cut tobacco passing through the wire suction forming groove 13. Both ends of the support post 2 are respectively inserted into the support post sleeves 6 on two corresponding wire suction plates 1, and the support post 2 plays a role in supporting the two wire suction plates 1 to ensure the relative position stability between the two wire suction plates 1.

[0029] In the embodiment of the present invention, the total width formed by the two wire suction plates 1 remains the same as that in the prior art, which is 20 mm, while the distance between the upper parts of the two wire suction plates 1 is increased from 4.8 mm in the prior art to 15.2 mm. At the same time, the width of the wire suction forming groove 13 is the same as that in the prior art, which is 7.4 mm. By opening the installation opening 11 on the wire suction plate 1, the distance between the upper parts of the two wire suction plates 1 is cleverly increased, thereby increasing the air intake of the wire suction beam device. At this time, the negative pressure channel between the wire suction plates 1 presents a structure that is wider at the top and narrower at the bottom, and this structural design can effectively avoid negative pressure loss. Due to the increase in air intake and the optimization of the negative pressure channel structure, during the cigarette rod production process, the cut tobacco can be adsorbed and formed more evenly, thereby achieving the effect of stable cigarette rod weight, and at the same time reducing the occurrence of the problem of empty end quality, and improving the quality and production stability of the cigarette rod product.

[0030] Although the specific implementation manner of the invention is described above in conjunction with the drawings, it is not a limitation to the protection scope of the present invention. Based on the technical solution of the present invention, various modifications or deformations that can be made by those skilled in the art without creative labor are still within the protection scope of the present invention.
