Description

A wire-suction beam device Technical Field

[0001] This utility model relates to the field of cigarette equipment technology, and in particular to a cigarette suction beam device. Background Technology

[0002] When the YJ17 feeding and forming unit is working, the air chamber is locked by a locking mechanism, forming a negative pressure chamber. The negative pressure is provided by a high-pressure fan. The lower part of the air chamber has a suction beam and a baffle, forming a suction forming groove. The negative pressure attracts and conveys the tobacco shreds forward, forming a tobacco bundle of a certain width under the action of the suction beam.

[0003] In the tobacco production industry, the tobacco suction beam device is a key piece of equipment in the cigarette forming process, and its performance directly affects the quality of the cigarettes and production efficiency. Referring to Figure 1, the existing tobacco suction beam device is usually composed of components such as the suction plate 100, and is mainly used to absorb and transport tobacco to achieve cigarette forming.

[0004] However, while the existing tobacco suction beam device has an overall width of 20mm, its upper negative pressure channel is only 4.8mm wide, and the width of the bottom contact area with the suction belt (the width of the tobacco forming groove 200) is 7.4mm. This device has certain technical defects. On the one hand, its structural design results in a small gap between the two suction plates 100, leading to insufficient air intake. Insufficient air intake affects the adsorption and conveying effect of tobacco, causing uneven distribution of tobacco during the forming process. On the other hand, the existing suction beam device's negative pressure channel, which is narrow at the top and wide at the bottom, is unreasonable. After passing from the top of the suction beam device to the bottom suction belt, the increased width easily causes negative pressure loss during shaping. This not only reduces the working efficiency of the suction beam device but also leads to unstable cigarette weight and quality problems such as hollow heads, seriously affecting the quality and production stability of cigarettes.

[0005] With the tobacco industry's increasing demands for cigarette quality, there is an urgent need to improve the existing cigarette-suction beam device to solve the aforementioned technical problems and meet production needs. Summary of the Invention

[0006] This invention addresses the shortcomings of existing technologies by developing a cigarette suction beam device. This invention increases the air intake by increasing the spacing between the plates through the "L"-shaped cross-section of the suction plate, and forms a negative pressure channel that is wider at the top and narrower at the bottom to reduce negative pressure loss. Combined with magnetic bead guidance and a stable support structure, it achieves stable cigarette weight, reduces the problem of empty cigarette heads, and improves production stability.

[0007] The technical solution to the technical problem solved by this utility model is as follows:

[0008] This application provides a wire-suction beam device, including two wire-suction plates, a pin shaft, and a magnetic bead;

[0009] The inner side of the wire-absorbing plate has an installation opening, so that the cross-section of the two wire-absorbing plates is "L" shaped and mirror symmetrically arranged; the bottom inner side of the wire-absorbing plate has a groove, and the grooves of the two wire-absorbing plates are arranged opposite each other to form a wire-absorbing forming groove, and the two installation openings are arranged opposite each other to form an installation groove; the width of the installation groove is greater than or equal to the width of the wire-absorbing forming groove.

[0010] The wire-absorbing plate is provided with a plurality of pin holes evenly distributed. The magnetic bead is sleeved on the outer wall of the pin. The two ends of the pin are inserted into the corresponding pin holes. The magnetic bead is installed between the two wire-absorbing plates through the pin.

[0011] As an improvement to the above solution, the wire-absorbing beam device further includes a support column, which is connected between the two wire-absorbing plates.

[0012] As an improvement to the above solution, the wire-absorbing plate is provided with a plurality of support holes evenly distributed, and the wire-absorbing plate is provided with support sleeves corresponding to the positions of the support holes, with the two ends of the support inserted into the corresponding support sleeves respectively.

[0013] As an improvement to the above solution, a pin sleeve corresponding to the pin hole is provided inwardly on the wire suction plate, and both ends of the pin are inserted into the corresponding pin sleeve.

[0014] As an improvement to the above solution, the width of the mounting groove is 15.2 mm, and the width of the wire-drawing forming groove is 7.4 mm.

[0015] Compared with existing technologies, the above solution has the following advantages or beneficial effects:

[0016] 1. Air intake and negative pressure optimization: The installation port of the suction plate is designed with an "L" shaped cross section to increase the spacing between the suction plates. This increases the air intake while keeping the total width constant, and forms a negative pressure channel that is wider at the top and narrower at the bottom, reducing negative pressure loss and stabilizing the adsorption pressure.

[0017] 2. Improve cigarette quality: Stable air intake and negative pressure ensure stable adsorption and delivery of tobacco, resulting in stable cigarette weight, reducing the problem of empty heads, and improving the quality of finished products.

[0018] 3. Reliable structure and function: Magnetic beads assist in tobacco shred forming, and the support column stabilizes the position of the suction plate, ensuring the stability of the device structure. All components work together to ensure the forming effect and working performance. Attached Figure Description

[0031] Referring to Figures 1-9, this embodiment provides a wire-absorbing beam device, including two wire-absorbing plates 1 arranged in a mirror image, a support column 2, a pin shaft 3, and a magnetic bead 4.

[0032] Each suction plate 1 has an inward and downward recessed inner side forming an installation opening 11, making the cross-section of the two suction plates 1 "L" shaped. A groove 12 is formed on the inner side of the bottom end of the suction plate 1. When the two suction plates 1 are arranged opposite each other, their grooves 12 form a suction forming groove 13, which is used to shape and guide the tobacco. The two installation openings 11 are also arranged opposite each other to form an installation groove 14, used to install the support column 2 and the magnetic bead 4. The width of the installation groove 14 is greater than the width of the suction forming groove 13, creating a negative pressure channel that is wider at the top and narrower at the bottom, to prevent negative pressure loss after entering the lower part of the suction beam device from the upper part.

[0033] Multiple pin holes and support holes are evenly spaced on the suction plate 1. Pin sleeves 5 and support sleeves 6 extend inward from the suction plate 1. The pin sleeve 5 corresponds to the pin hole, meaning it is a tubular structure extending inward from the pin hole. Similarly, the support sleeve 6 corresponds to the support hole, also a tubular structure extending inward from the support hole. Magnetic beads 4 are fitted onto the outer wall of the pin 3. Both ends of the pin 3 are inserted into the corresponding pin sleeves 5 on the two suction plates 1. This connection method securely mounts the magnetic beads 4 between the two suction plates 1. The magnetic beads 4 can effectively attract or guide the tobacco passing through the suction forming groove 13.

[0034] The two ends of the support column 2 are respectively inserted into the support column sleeves 6 on the two corresponding wire suction plates 1. The support column 2 serves to support the two wire suction plates 1 and ensure the relative position between the two wire suction plates 1 is stable.

[0035] In this embodiment of the invention, the total width formed by the two suction plates 1 remains the same as in the prior art, at 20mm, while the distance between the upper parts of the two suction plates 1 is increased from 4.8mm in the prior art to 15.2mm. Simultaneously, the width of the suction forming groove 13 remains the same as in the prior art, at 7.4mm. By opening an installation port 11 on the suction plate 1, the distance between the upper parts of the two suction plates 1 is cleverly increased, thereby increasing the air intake of the suction beam device. At this time, the negative pressure channel between the suction plates 1 exhibits a structure that is wider at the top and narrower at the bottom. This structural design effectively avoids negative pressure loss. Due to the increased air intake and optimized negative pressure channel structure, during cigarette production, the tobacco shreds can be more evenly absorbed and formed, achieving a stable cigarette weight while reducing the occurrence of hollow head quality problems, thus improving the quality and production stability of the cigarette product.

[0036] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
