DETAILED DESCRIPTION

[0025] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, exemplary embodiments of the present invention are described below in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding. These details should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0026] In the description of this utility model, it should be noted that the term "including" and its variations represent open inclusion, that is, "including but not limited to." The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0027] The utility model provides a cigarette holder mold box conveyor belt cleaning device, Figure 1-Figure 3As shown, it includes a mold box cover 1, a blower mechanism and a start sensor; the mold box cover 1 is provided with a blowing hole; the blower mechanism includes an air pipe, a control valve 21 and a controller 22, the output end of the air pipe is connected to the blowing hole, and the input end thereof is connected to the air source, and the control valve 21 is arranged on the air pipe; the start sensor and the control valve 21 are both electrically connected to the controller 22, and the start sensor sends a blowing signal to the controller 22; the controller 22 controls the control valve 21 to open according to the blowing signal.

[0028] The startup sensor can use an existing sensor in the ZB45 packaging machine. Preferably, the packaging machine's open / close signal sensor 23 can serve as the startup sensor. The controller 22 can use the packaging machine's PLC controller 22, and the control valve 21 can use a solenoid valve electrically connected to the PLC controller 22. The ZB45 packaging machine's open / close signal sensor 23 uses a 2S117 sensor. During normal operation, the ZB45 packaging machine's open / close signal sensor 23 is constantly triggered. When production or a stage of production ends, the open / close signal sensor 23 disconnects, deactivating it and discontinuing the supply of cigarettes from the cigarette storage, causing the machine to operate without material. At this point, the open / close signal sensor 23 transmits a disconnection signal as a blow signal to the controller 22. Based on the received blow signal, the controller 22 controls the control valve 21 to open, allowing compressed air from the air source to be supplied through the air pipe and blown into the mold box cover 1 through the blow hole, purging the cigarette foam inside the mold box cover 1 and reducing cigarette foam accumulation on the conveyor belt 6. The air source can be the workshop's compressed air source. The blowing time can be controlled by a delay function, so that the control valve 21 automatically closes after being opened for a certain period of time. A delay module can be set in the controller 22, and the delay module can set a suitable delay time according to the cleaning effect. Preferably, the delay time set by the delay module includes 200-400s. For example, the delay time can be set to 200s, 250s, 300s, 350s, 400s, etc. The disconnection signal of the air-opening signal sensor 23 is used as a blowing signal, and the blowing function is automatically turned on at the end of production. By controlling the time of turning on the blowing function through the delay module, the level of automated operation can be improved, and blowing of cigarettes during the production process can be avoided, which causes tobacco shreds to fall off and affects the production process. The blowing is stable and energy-saving.

[0029] In one embodiment, reference Figure 2As shown, the controller 22, the control valve 21, and the start sensor are powered by a power supply. The control valve 21 is directly electrically connected to the controller 22, and the controller 22 can directly control the opening and closing of the control valve 21. When the controller 22 receives a blow signal from the air opening signal sensor 23, the controller 22 directly sends a blow command to the control valve 21, directly controlling the control valve 21 to open, connecting the air source for blow cleaning; after the control valve 21 opens for a preset delay time, the controller 22 controls the control valve 21 to close, disconnecting the air source and stopping the blow cleaning.

[0030] In one embodiment, reference Figure 3 As shown, the controller 22, the control valve 21, and the start sensor are powered by a power supply. A relay 24 is provided between the control valve 21 and the power supply, and the relay 24 is electrically connected to the controller 22. The PLC controller 22 indirectly controls the on / off of the control valve 21 by directly controlling the on / off of the relay 24. When the controller 22 receives the blowing signal from the air opening signal sensor 23, the controller 22 sends a blowing instruction to the relay 24 to control the relay 24 to be turned on. At this time, the control valve 21 is connected to the power supply, the control valve 21 is powered on and opened, and the air source is connected for blowing and cleaning; after the relay 24 is turned on for a preset delay time, the controller 22 controls the relay 24 to be turned off. At this time, the control valve 21 is disconnected from the power supply, the control valve 21 is powered off and closed, and the air source is disconnected to stop blowing and cleaning. Controller 22 controls the on / off state of control valve 21 by switching relay 24. Relay 24 acts as an isolation device, protecting the circuit. This prevents malfunctions of control valve 21 (such as a stuck solenoid valve core) from causing reverse current flow and potentially damaging the output of PLC controller 22. This prevents burnout and reduces the frequency of damage. A Y117 solenoid valve can be used for control valve 21, and a KA117 miniature relay can be used for relay 24.

[0031] Inside the mold box cover 1, smoke foam mainly accumulates on the upper surface of the pulley bracket 7 and the conveyor belt 6. The pulley bracket 7 is located above the conveyor belt 6. When too much smoke foam accumulates on the pulley bracket 7, it will fall from the gap between the synchronous pulley 8 and the pulley bracket 7 onto the conveyor belt 6. Therefore, it is necessary to blow and clean the smoke foam accumulated on the pulley bracket 7 and the conveyor belt 6 at the same time. Figure 1 and Figure 4 As shown, the blowing holes include a first vent hole 31 and a second vent hole 32, wherein the first vent hole 31 faces the conveyor belt 6 at the bottom of the mold box, and the second vent hole 32 faces the upper surface of the pulley bracket 7. Figure 4As shown by the middle arrow →, compressed air blows into the mold box cover 1 from the first air vent 31 and the second air vent 32, which can respectively purge the smoke foam accumulated on the conveyor belt 6 and the pulley bracket 7. A mold box cover 1 is provided on each side of the synchronous pulley 8, and the synchronous pulley 8 is housed in a cavity formed by the two mold box covers 1 for protection. The blowing hole can be provided in either of the two mold box covers 1 to facilitate the smoke foam to fall to the bottom of the mold box cover 1. The air supply pipe includes a first air pipe 41, a second air pipe 42 and a main pipe 43. One end of the first air pipe 41 and the second air pipe 42 are connected to the first air vent 31 and the second air vent 32 respectively, and the other end is connected to the main pipe 43. The main pipe 43 is connected to the air source. Preferably, the first and second air vents 31 and 32 are respectively provided with first and second air pipe plugs, and the first and second air pipes 41 and 42 are respectively connected to the first and second air pipe plugs. The first and second air pipes 41 and 42 are connected to one end of a main pipe 43 via a three-way air pipe joint. The air pipe joint allows for convenient and quick connection of the air pipes. The control valve 21 is provided on the main pipe 43 and can simultaneously activate the blowing function of the first and second air vents 31 and 32.

[0032] In one embodiment, Figure 5 As shown, the cleaning device also includes a guide plate 5, which is arranged in an inverted V-shape below the gap between the pulley bracket 7 and the synchronous pulley 8. A claw 51 can be provided on the guide plate 5, with threaded holes provided at appropriate locations on the frame. The claw 51 is fastened to the frame via bolts, making installation convenient. The width L1 of the guide plate 5 is greater than the width L2 of the conveyor belt 6. The guide plate 5 forms an umbrella shape, shielding the conveyor belt 6. When the airflow lifts the smoke accumulated on the pulley bracket 7, the smoke falls onto the guide plate 5, slides off the guide plate 5 to the sides, and lands on the bottom of the mold box cover 1. If too much smoke accumulates on the pulley bracket 7 and falls through the gap between the pulley bracket 7 and the synchronous pulley 8, it can also fall onto the guide plate 5, slide off the guide plate 5 to the sides, and land on the bottom of the mold box cover 1, thus preventing the smoke from falling onto the conveyor belt 6.

[0033] The mold box cover 1 has an opening 11 at the bottom. After the smoke foam falls to the bottom of the mold box cover 1, most of it can be discharged through the opening 11. There is no need to remove the mold box cover 1 to clean the smoke foam on a daily basis. The smoke foam that still accumulates at the bottom of the mold box cover 1 will not affect the conveyor belt 6, and can be easily cleaned during equipment maintenance. To facilitate the collection and cleaning of smoke foam, the cleaning device also includes a collection box, which is arranged below the opening 11 at the bottom of the mold box cover 1. In this way, when the smoke foam is discharged from the opening 11 at the bottom of the mold box cover 1, it can fall into the collection box, preventing the smoke foam from falling to the ground and causing a mess.

[0034] Through this cleaning device, the smoke foam accumulated on the pulley bracket 7 and the smoke foam accumulated on the mold box conveyor belt 6 can be blown and cleaned at the same time, reducing the accumulation of smoke foam on the conveyor belt 6, effectively reducing the occurrence of tooth jamming and breakage of the conveyor belt 6, and at the same time reducing the occurrence of tobacco insect breeding and aggregation caused by smoke foam accumulation, effectively improving daily cleaning efficiency.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
