Description

Technical Field

[0001] This utility model belongs to the technical field of cigarette packaging equipment, specifically relating to an aluminum foil conveying device for a cigarette packaging machine. Background Technology

[0002] The aluminum foil conveying device in a cigarette packaging machine uses two suction belts to transport the cut aluminum foil to the next station. The negative pressure chamber and main suction channel of this device are prone to blockage. Blockage reduces the suction value, preventing the inner lining paper conveyor belt from properly adsorbing and transporting the inner lining paper. This causes the aluminum foil to skew during transport, resulting in quality defects such as misaligned aluminum foil, and even blockage leading to machine downtime. Therefore, it is necessary to clean the suction channels and ducts to restore equipment operation. The aluminum foil conveying device needs to be disassembled and cleaned every 3 days.

[0003] Chinese utility model patent (publication number: CN218662529U) discloses an inner liner paper conveying device for cigarette packaging machines. Although it solves the problem that the existing inner liner paper conveying equipment has problems such as the suction conveyor belt being easily worn by the suction plate, resulting in poor flatness of the inner liner paper during the conveying process.

[0004] It utilizes the first through hole, the second through hole, and two strip-shaped through holes on the suction plate to connect the first groove and the suction conveyor belt. However, in actual use, due to the gaps between the first through hole, the second through hole, and the two strip-shaped through holes, the suction plate will block the first groove of the substrate. When the first groove and each through hole are blocked and cannot be cleared by the blowing of the positive pressure source, the suction conveyor belt, the suction plate, and each accessory must be disassembled before cleaning, which is troublesome and affects production efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide an aluminum foil conveying device for a cigarette packaging machine, which solves the problem of cumbersome disassembly and assembly during cleaning caused by structural defects in existing conveying devices, thus affecting production efficiency.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0007] An aluminum foil conveying device for a cigarette packaging machine includes:

[0008] The base has a main air intake duct horizontally opened on it. One end of the main air intake duct is connected to the side of the base and is connected to a negative pressure pipe. The base has a groove that is connected to the main air intake duct.

[0009] A suction plate is mounted on a base and has suction grooves that correspond to recesses.

[0010] A cover plate, which is detachably mounted on a suction plate, and the cover plate has several suction holes;

[0011] The air intake hole is connected to the groove via the air intake slot;

[0012] The suction plate is equipped with a suction conveyor belt, which has through holes that are positioned opposite to the suction holes.

[0013] Further specified, the cover plate has a connecting groove on the side near the suction plate, and the connecting groove corresponds to the suction groove;

[0014] The air intake hole is connected to the air intake groove via a connecting groove.

[0015] This structural design, through the setting of the connecting groove, makes the cavity volume formed by the connecting groove, the suction groove and the groove larger than the original cavity volume formed by the suction groove and the groove, thus accommodating more impurities, reducing the risk of blockage, and making it highly practical.

[0016] Further specified, the base has an installation hole at the end away from the negative pressure pipe, and the installation hole is connected to the main air intake duct and is coaxially arranged;

[0017] A sealing head can be detachably installed inside the mounting hole.

[0018] This structural design, with mounting holes on the base that are coaxially connected to the main air intake duct and in which sealing heads can be detachably installed, allows for easy cleaning of the main air intake duct if it becomes clogged during use. The sealing heads can be removed, and the duct can be cleaned through the mounting holes using tools such as a blower and screwdriver, without needing to remove the negative pressure pipe connected to the main air intake duct and clean from the side connected to the negative pressure pipe. This makes cleaning more convenient and highly practical.

[0019] Further specifying, the sealing head is a bolt, and the mounting hole is a threaded hole.

[0020] This structural design uses bolts as sealing heads, and the bolts are screwed into the threaded holes to seal the mounting holes. It has a simple structure, high reliability, and strong practicality.

[0021] Further, the cover plate has stepped holes, and a fixing bolt passes through the stepped holes and is screwed onto the suction plate.

[0022] This structural design allows for the detachable installation of the cover plate and the suction plate by using fixing bolts that pass through the stepped holes and are screwed to the suction plate. The structure is simple, easy to install, and highly practical.

[0023] Furthermore, the stepped holes are located outside the projection area of ​​the suction conveyor belt on the cover plate.

[0024] This structural design, by limiting the position of the stepped holes, can prevent the suction conveyor belt from obstructing the fixing bolts inserted in the stepped holes, making disassembly and assembly more convenient and highly practical.

[0025] Furthermore, the cover plate is also provided with a secondary threaded hole.

[0026] This structural design, by opening a secondary threaded hole on the cover plate, allows for the insertion of a new bolt into the secondary threaded hole after the fixing bolt is removed from the suction plate. This lifts the cover plate off the suction plate, and the cover plate can then be removed from the suction plate by pulling the fixing bolt, making it more convenient to use.

[0027] The utility model adopting the above technical solution has the following advantages:

[0028] 1. The air suction holes on the cover plate connect the through holes on the suction conveyor belt with the grooves on the base. By utilizing the detachable installation of the cover plate and the suction plate, as well as the elasticity of the suction conveyor belt itself, the cover plate can be removed separately and the suction conveyor belt can be opened during cleaning to expose the grooves and suction channels. This allows workers to clean the grooves, suction channels, and suction holes. The easy disassembly and assembly can improve cleaning efficiency and thus increase production efficiency.

[0029] 2. By setting mounting holes on the base that are coaxial with and connected to the main air intake duct, and by detachably installing a sealing head in the mounting holes, the main air intake duct can be cleaned by removing the sealing head after it becomes blocked during use, using tools such as a blower and screwdriver through the mounting holes, without having to remove the negative pressure pipe connected to the main air intake duct and clean from the side of the main air intake duct connected to the negative pressure pipe. This makes cleaning more convenient and practical. Attached Figure Description

[0041] like Figures 1-4 As shown, the aluminum foil conveying device of this utility model for a cigarette packaging machine includes:

[0042] The base 1 has a main air intake duct 11 horizontally opened on the base 1. One end of the main air intake duct 11 is connected to the side of the base 1 and is connected to a negative pressure pipe. The base 1 has a groove 12, which is connected to the main air intake duct 11.

[0043] The suction plate 2 is mounted on the base 1. The suction plate 2 has a suction groove 20, which corresponds to the groove 12.

[0044] Cover plate 3 is detachably installed on suction plate 2, and several suction holes 32 are provided on cover plate 3.

[0045] The suction hole 32 is connected to the groove 12 via the suction groove 20;

[0046] A suction conveyor belt 4 is installed on the suction plate 2. The suction conveyor belt 4 has a through hole, which is arranged opposite to the suction hole 32.

[0047] A connecting groove 31 is provided on the side of the cover plate 3 near the suction plate 2, and the connecting groove 31 corresponds to the suction groove 20.

[0048] The suction hole 32 is connected to the suction groove 20 via the connecting groove 31.

[0049] By setting the connecting groove 31, the cavity volume formed by the connecting groove 31, the suction groove 20 and the groove 12 is larger than the original cavity volume formed by the suction groove 20 and the groove 12, thus accommodating more impurities, reducing the risk of blockage, and making it more practical.

[0050] The base 1 has an installation hole at the end away from the negative pressure pipe. The installation hole is connected to the main air intake duct 11 and is coaxially arranged.

[0051] A sealing head 110 can be detachably installed inside the mounting hole.

[0052] By providing a mounting hole on the base 1 that is coaxially connected to the main air intake duct 11, and detachably installing a sealing head 110 in the mounting hole, the sealing head 110 can be removed after the main air intake duct 11 becomes blocked during use. The main air intake duct 11 can then be cleaned through the mounting hole using tools such as a blower and screwdriver, without having to remove the negative pressure pipe connected to the main air intake duct 11 and clean from the side of the main air intake duct 11 connected to the negative pressure pipe. This makes cleaning more convenient and practical.

[0053] The sealing head 110 is a bolt, and the mounting hole is a threaded hole.

[0054] In practice, depending on the actual situation, a rubber plug can also be selected as the sealing head 110 to complete the sealing of the mounting hole. In this embodiment, a bolt is used as the sealing head 110, and the mounting hole is sealed by screwing the bolt into the threaded hole. The structure is simple, reliable, and practical.

[0055] The width of groove 12 is 6mm.

[0056] The cover plate 3 has a stepped hole 33, and a fixing bolt is inserted into the stepped hole 33. The fixing bolt is screwed onto the suction plate 2.

[0057] In practice, depending on the actual situation, a method such as setting a buckle between the cover plate 3 and the suction plate 2 can be selected to achieve the detachable installation of the cover plate 3 and the suction plate 2. In this embodiment, the cover plate 3 and the suction plate 2 are detachably installed by screwing the fixing bolt through the stepped hole 33 to the suction plate 2. The structure is simple, the installation is convenient, and the practicality is strong.

[0058] The stepped hole 33 is located outside the projection area of ​​the suction conveyor belt 4 onto the cover plate 3.

[0059] In practice, depending on the actual situation, the stepped hole 33 can also be set in the projection area of ​​the suction conveyor belt 4 on the cover plate 3.

[0060] The cover plate 3 is also provided with a secondary threaded hole 34.

[0061] By opening a secondary threaded hole 34 on the cover plate 3, after removing the fixing bolt from the suction plate 2, a new bolt can be screwed into the secondary threaded hole 34, thereby lifting the cover plate 3 off the suction plate 2. Then, the cover plate 3 can be removed from the suction plate 2 by pulling the fixing bolt, making it more convenient to use.

[0062] In this embodiment, when the air intake channel is blocked, the sealing head 110 in the installation hole is removed, the sealing head 110 is removed, and the main air intake channel 11 is cleaned from the installation hole using tools such as a blower and screwdriver, without having to remove the negative pressure pipe connected to the main air intake channel 11 and clean from the side of the main air intake channel 11 connected to the negative pressure pipe.

[0063] Remove the fixing bolts that are screwed onto the suction plate 2 through the stepped hole 33, and then screw a new bolt into the secondary threaded hole 34 to lift the cover plate 3 off the suction plate 2. Then, remove the cover plate 3 from the suction plate 2 by pulling the fixing bolts. Then, push aside the suction conveyor belt 4 to expose the groove 12 and the suction channel 20 for the staff to clean.

[0064] Then, the connecting groove 31 and the suction hole 32 of the cover plate 3 can be cleaned separately.
