Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, and in particular to an automatic cleaning and transport device and a cigarette packaging production line. Background Technology

[0002] In the specialized production line of the cigarette packaging workshop, the transparent paper packaging machine is responsible for packaging high-end hardwood cigarette cartons with transparent paper. The operation process is as follows: workers place the unwrapped cartons of cigarettes onto the conveyor belt, which then feeds them into the transparent paper packaging machine to complete the packaging process. Because the hardwood cartons of cigarettes are made of cardboard, paper scraps or dust easily accumulate on the surface of the cartons. Over time, a layer of dirt composed of a mixture of paper scraps and dust gradually accumulates on the surface of the conveyor belt of the packaging machine.

[0003] During the conveyor belt's cyclic rotation, these contaminants can have multiple negative impacts: on the one hand, they can contaminate cigarette packs, leading to a decline in the quality of transparent paper packaging, resulting in defective products and affecting the stability of product quality; on the other hand, the mixture can adhere to the tension rollers of the conveyor belt, accelerating their wear, which in turn can cause the conveyor belt to run off-track, ultimately damaging the conveyor belt and increasing equipment maintenance costs and downtime.

[0004] Therefore, there is an urgent need to propose an automatic cleaning and transportation device and a cigarette packaging production line to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an automatic cleaning and conveying device and a cigarette packaging production line, which can remove dirt from the surface of the conveyor belt, thereby improving the quality of transparent paper packaging and increasing the product qualification rate; extending the service life of the conveyor belt and tension roller, and ensuring the continuity and stability of normal production.

[0010] The second cleaning mechanism includes a positive pressure cleaning pipe, an air pipe, and a positive pressure device. The positive pressure cleaning pipe has an air passage inside and multiple air jet holes communicating with the air passage on its surface. The air pipe is connected between the output end of the positive pressure device and the input end of the air passage.

[0011] In some alternative embodiments, the cleaning tension roller is adjustablely connected to the frame in a direction close to or away from the conveyor belt.

[0012] In some alternative embodiments, the first cleaning mechanism further includes a first adjusting member, an adjusting groove extending along its height direction is provided on the frame, the shaft of the cleaning tension roller is slidably engaged with the adjusting groove, the first adjusting member is threadedly connected to the frame, and passes through the side wall of the adjusting groove to connect with the shaft of the cleaning tension roller.

[0013] In some alternative embodiments, the positive pressure cleaning pipe is positioned downstream of the cleaning tension roller along the running direction of the conveyor belt.

[0014] In some alternative embodiments, the axis of the jet orifice is inclined from bottom to top in the upstream direction of the conveyor belt.

[0015] In some alternative embodiments, the angle between the axis of the jet orifice and the surface of the conveyor belt is 30° to 80°.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0035] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0037] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0038] like Figures 1-5As shown, this embodiment provides an automatic cleaning and transport device, including a frame 1, a drive roller 2, a driven roller 3, and a conveyor belt 4. The drive roller 2 and the driven roller 3 are parallel, spaced apart, and rotatably connected to the frame 1 to tension the conveyor belt 4, which is used to transport cigarette packs 100.

[0039] The automatic cleaning and conveying device also includes a first cleaning mechanism 5, which includes a cleaning tension roller 51. The surface of the cleaning tension roller 51 is covered with bristles 52. The cleaning tension roller 51 is positioned below the conveyor belt 4 and rotatably connected to the frame 1. The bristles 52 contact the conveyor belt 4. The conveyor belt 4 drives the cleaning tension roller 51 to rotate, thus tensioning the conveyor belt 4. The bristles 52 on the surface of the cleaning tension roller 51 remove dirt from the surface of the conveyor belt 4. This prevents dirt from adhering to the tension roller, reducing wear on the tension roller and the conveyor belt 4, extending the service life of the conveyor belt 4 and the tension roller, and ensuring the continuity and stability of normal production. Furthermore, it prevents the cigarette packs 100 from being contaminated by dirt on the surface of the conveyor belt 4, thereby improving the quality of the transparent paper packaging and increasing the product qualification rate.

[0040] In addition, the automatic cleaning and conveying device also includes a second cleaning mechanism 6, which includes a positive pressure cleaning pipe 61, an air pipe 62, and a positive pressure device. The positive pressure cleaning pipe 61 has an air passage inside, and its surface has multiple air jet holes 611 that communicate with the air passage. The air pipe 62 is connected between the output end of the positive pressure device and the input end of the air passage. Gas is sprayed through the air jet holes 611 on the surface of the positive pressure cleaning pipe 61 to blow away the floating dust on the surface of the cleaning roller, which can further improve the surface cleanliness of the conveyor belt 4.

[0041] The surface of the conveyor belt 4 is cleaned twice by the first cleaning mechanism 5 and the second cleaning mechanism 6, which significantly improves the cleaning effect of the conveyor belt 4.

[0042] like Figure 3 As shown, in some optional embodiments, the cleaning tension roller 51 is adjustablely connected to the frame 1 in the direction of approaching or moving away from the conveyor belt 4. By adjusting the cleaning tension roller 51 to approach or move away from the conveyor belt 4, the conveyor belt 4 can maintain proper tension, which can prevent the conveyor belt 4 from running off track or slipping, and ensure the stability of the cigarette pack 100 transportation.

[0043] In some optional embodiments, the first cleaning mechanism 5 further includes a first adjusting member 53. An adjusting groove 11 extending in the direction of approaching or moving away from the conveyor belt 4 is provided on the frame 1. The rotating shaft of the cleaning tension roller 51 is slidably engaged with the adjusting groove 11. The first adjusting member 53 is threadedly connected to the frame 1 and passes through the side wall of the adjusting groove 11 to connect with the rotating shaft. By turning the first adjusting member 53, the cleaning tension roller 51 can be adjusted to approach or move away from the conveyor belt 4, thereby adjusting the tension of the conveyor belt 4.

[0044] like Figures 1-3 As shown, in some optional embodiments, the positive pressure cleaning pipe 61 is positioned downstream of the cleaning tension roller 51 along the running direction of the conveyor belt 4. After the bristles 52 rub against the conveyor belt 4, they sweep up dirt from the surface of the conveyor belt 4, generating a large amount of dust. This dust easily re-adheres to the surface of the conveyor belt 4 under static electricity. The positive pressure cleaning pipe 61, positioned downstream, forms a "cleaning air wall," blocking the dust before it reaches the air wall, further improving the cleaning effect of the conveyor belt 4.

[0045] In some optional embodiments, the axis of the jet nozzle 611 is inclined from bottom to top towards the upstream direction of the conveyor belt 4, so that the jet gas can form an opposing force with the conveyor belt 4, which is beneficial to enhance the impact effect of the jet gas on the conveyor belt 4, thereby significantly improving the cleaning effect. At the same time, the inclined air wall forms a directional sweeping of dust and lint, which can enhance the barrier effect and effectively prevent dust and lint from flying in all directions under the impact of gas, avoiding dust and lint from being re-adsorbed onto the conveyor belt 4 downstream of the positive pressure cleaning pipe 61. Thus, while improving the cleaning efficiency of the conveyor belt 4, it further ensures the durability of cleaning and reduces the adverse effects on the quality of transparent paper packaging caused by dust and lint residue or secondary adsorption.

[0046] In some optional embodiments, the angle between the axis of the jet nozzle 611 and the surface of the conveyor belt 4 is 30° to 60°, which can ensure the impact effect of the gas on the conveyor belt 4 while ensuring the blocking effect of dust and lint. Exemplarily, the angle between the axis of the jet nozzle 611 and the surface of the conveyor belt 4 is not limited to 30°, 45° or 60°, and is not limited here.

[0047] In some optional embodiments, the second cleaning mechanism 6 further includes a pressure regulating valve 63, which is disposed between the air pipe 62 and the air passage to regulate the pressure of the injected gas, so as to ensure the impact effect on the conveyor belt 4 and the blocking effect on dust and lint, and prevent the debris from being scattered everywhere due to excessive wind force.

[0048] In some optional embodiments, the second cleaning mechanism 6 further includes an on / off valve and a detector. The on / off valve is located at the output end of the positive pressure device, and the detector is used to detect the push-smoke rhythm of the packaging machine 200. The on / off valve is communicatively connected to the detector. The conveyor belt 4 operates intermittently according to the push-smoke rhythm of the packaging machine 200, conveying the cigarette packs 100 to the packaging machine 200. The on / off valve controls the gas flow according to the push-smoke rhythm of the packaging machine 200, intermittently purging the conveyor belt 4, thereby achieving the purpose of saving air energy consumption.

[0049] Optionally, the detector may include, but is not limited to, an infrared sensor or a pressure sensor, for detecting the pushing action of the packaging machine 200, thereby sending a pushing rhythm signal.

[0050] For example, the on / off valve includes, but is not limited to, a solenoid valve.

[0051] like Figure 4 As shown, in some optional embodiments, the conveying device further includes a tension adjustment mechanism 7, which is connected between the shaft of the tension roller and the frame 1, and is used to adjust the distance between the driven roller 3 and the driving roller 2 to tension the conveyor belt 4 and ensure that the conveyor belt 4 operates normally.

[0052] Specifically, the frame 1 has a waist-shaped hole 12 extending along its length. The tension adjustment mechanism 7 includes a telescopic connector 71 and a locking member 72. The telescopic connector 71 is connected between the tension roller shaft and the frame 1 and can be telescopically adjusted along the length of the frame 1 to provide support for the driven roller 3. The locking member 72 can slide through the waist-shaped hole 12, and one end is threadedly connected to the tension roller shaft, while the other end is used to abut against the frame 1, thereby locking the driven roller 3 to the frame 1.

[0053] like Figures 1-5 As shown, in some optional embodiments, this embodiment also provides a cigarette packing production line, including a packaging machine 200 and an automatic cleaning and conveying device of any of the above embodiments. The unloading end of the automatic cleaning and conveying device is connected to the loading end of the packaging machine 200, and is used to convey the cigarette packs 100 to the packaging machine 200. The packaging machine 200 is capable of packaging the cigarette packs 100 with transparent paper.

[0054] The packaging machine 200 includes a pushing mechanism 210, which is used to turn and push the cigarette packs 100 to realize the turning and transportation of the cigarette packs 100 from the automatic cleaning and transport device to the packaging machine 200. The detector can detect the pushing rhythm of the pushing mechanism 210.

[0055] By adopting the above-mentioned automatic cleaning and transport device, dirt on the surface of conveyor belt 4 can be removed, thereby improving the quality of transparent paper packaging and increasing the product qualification rate; extending the service life of conveyor belt 4 and tension roller, and ensuring the continuity and stability of normal production.

[0056] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
