Detailed implementation mode

[0019] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] See Figure 2 , the present invention provides a cleaning structure for a bag nozzle opening. The cleaning structure for the bag nozzle opening includes a material transfer guide rail 1 for supporting the bag body, a material transfer component 2 for driving the bag body 00 to move along the material transfer guide rail 1, a cleaning liquid spraying assembly 3 provided on one side of the material transfer guide rail 1, and a cleaning liquid cleaning component for blowing down the cleaning liquid remaining at the bag nozzle opening 01. The material transfer guide rail 1 adopts a double-slide rail structure. For the bag body 00 in a supported state, the clamping projection 02 at the bag nozzle opening 01 thereof clamps the material transfer guide rail 1 (the bag nozzle opening 01 is placed in the transfer space in the middle of the double-slide rail structure), and the bag body 00 is driven to move by the material transfer component 2. In this embodiment, the material transfer component 2 is a turntable structure (when working, the turntable structure is driven by a servo rotating motor to rotate intermittently at equal angles), and at least one card slot 21 for placing the bag nozzle opening 01 is provided on its outer edge. The material transfer component 2 in a rotating state uses the card slot 21 to push the bag nozzle opening 01 to realize the movement of the bag body 00; correspondingly, the material transfer guide rail 1 is an arc-shaped guide rail with an arc consistent with the outer edge arc of the material transfer component 2. Of course, the material transfer guide rail 1 can also adopt a straight guide rail structure, and the corresponding material transfer component 2 adopts a driving structure matching the straight guide rail structure.

[0021] See Figure 2 , the cleaning liquid spraying assembly 3 includes a movable nozzle 31 for spraying cleaning liquid (water or other cleaning liquid) and a driving member for driving the movable nozzle 31 to rotate around the bag nozzle opening 01; the movable nozzle 31 is connected to a feeder (liquid pump) through a hose; during the rotation process of the movable nozzle 31 (the rotation angle thereof can be set as required), its spraying direction is always directed towards the bag nozzle opening 01; cleaning liquid is sprayed during the rotation process of the movable nozzle 31 to realize the comprehensive cleaning of the outer wall of the bag nozzle opening 01.

[0022] See Figure 2 and Figure 3, the cleaning liquid cleaning component includes an air duct 41 facing the bag nozzle 01 and a gas supply component connected thereto; specifically, an air flow nozzle 42 is provided above the cleaning liquid spraying component 3, and the air flow nozzle 42 is connected to the gas supply component. After the movable nozzle 31 finishes cleaning, the cleaning liquid cleaning component blows air flow against the outer wall of the bag nozzle 01, and uses the air flow to blow off the cleaning liquid remaining on the outer wall of the bag nozzle 01, so as to avoid secondary pollution caused by the remaining cleaning liquid.

[0023] Preferably, a plug 5 for blocking the opening of the bag nozzle 01 during the cleaning process is provided at the opening of the air flow nozzle 42 of the present invention; the air flow nozzle 42 is driven by a lifting component to approach or move away from the position of the bag nozzle 01 (the air flow nozzle 42 can be vertically lifted or lowered) to drive the plug 5 to block or unblock; and the air duct 41 is provided around the plug 5, and the plug 5 does not affect the flow of air.

[0024] In this embodiment, to improve the integration of the device, the rotation of the movable nozzle 31 is driven by the air flow nozzle 42. Specifically, the driving member is a lever 43 provided on the side wall of the air flow nozzle 42, and the end of the lever 43 is connected to the movable nozzle 31. After the air flow nozzle 42 is driven by a lifting component to approach the position of the bag nozzle 01 (the plug 5 enters the blocking state), it then rotates to drive the rotation of the movable nozzle 31.

[0025] In the first embodiment, the connecting end of the lever 43 is directly fixed to the movable nozzle 31.

[0026] See Figure 2 、 Figure 3 、 Figure 7 、 Figure 8 and Figure 9, in the embodiment shown in the figure, to prevent the cleaning liquid supply hose connected to the movable nozzle 31 from being entangled with the equipment components due to excessive rotation of the air flow nozzle 42, which may affect the normal operation of the equipment, a set of cleaning liquid spraying components 3 is provided on each side of the material transfer guide rail 1. During the cleaning process, each movable nozzle 31 only needs to rotate by nearly 180 degrees. At the same time, the cleaning liquid spraying component 3 further includes a nozzle support 32 installed on the frame and used to support the movable nozzle 31; a placement platform is provided at the end of the nozzle support 32. When the movable nozzle 31 is in the undriven state, the nozzle support 32 is placed on the placement platform; the movable nozzle 31 and the nozzle support 32 are connected by a limiting connector. The limiting connector can be a straight spring. Considering the limited stretching length of the straight spring, in this embodiment, the limiting connector includes a flexible connector connecting the nozzle support 32 and the movable nozzle 31 and a tensioning component that tightens the flexible connector when the driving member rotates and resets to reduce the distance between the nozzle support 32 and the movable nozzle 31. The flexible connector is a pull rope 61; the tensioning component is a tensioning wheel 62 (a torsion spring is installed inside the tensioning wheel 62 to provide the rotation reset effect). In the initial state, the pull rope is wound around the tensioning wheel.

[0027] The lifting component for driving the air flow nozzle 42 to lift and work can use a cylinder, and the mechanism for driving the air flow nozzle 42 to rotate includes a first meshing disk provided on the piston rod of the cylinder, a second meshing disk that can mesh with it, and a motor for driving the second meshing disk to rotate. After the cylinder drives the air flow nozzle 42 to descend to a predetermined position, the first meshing disk will mesh with the second meshing disk, and the motor can drive the air flow nozzle 42 to rotate and work.

[0028] In addition, in the present invention, when the air flow nozzle 42 is in the upper position in the uncleaned state (the plug 5 is away from the bag mouth 01 position), there is a distance between the movable nozzle 31 and the nozzle support 32, resulting in the torsion spring or straight spring being in a stretched state all the time. To ensure the service life of the torsion spring or straight spring, in this application, a slot 311 for conveniently inserting the lever 43 is provided on the side wall of the movable nozzle 31, and a positioning protrusion 312 for stabilizing the connection stability between the lever 43 and the movable nozzle 31 is provided in the slot 311 at the connecting end of the lever 43.

[0029] After the air flow nozzle 42 descends to the lower position (the plug 5 enters the sealing state), the lever 43 is inserted into the slot 311 of the movable nozzle 31, and by the positioning action of the positioning protrusion 312, the rotation state of the lever 43 driving the movable nozzle 31 is stabilized.

[0030] See Figure 3 、 Figure 4 and Figure 5At the same time, in order to avoid the rotation of the airflow nozzle 42, which may cause the plug 5 to be not tightly sealed (there may be a gap between the rotating plug 5 and the bag tube mouth 01), and to avoid the rotation of the bag body 00, which may cause unstable connection with the material transmission guide rail 1, and to ensure the stable progress of the airflow blowing process after the cleaning is completed, the plug 5 of the present application can be rotatably installed in the airflow nozzle 42; there is an airflow blocking structure for blocking the airflow between the airflow nozzle 42 and the plug 5, which includes a first blocking plate 51 arranged in the airflow nozzle 42 and a second blocking plate 52 arranged at the end of the plug 5; both plates are provided with through holes 53, and when the airflow nozzle 42 and the plug 5 rotate relative to each other so that the two through holes 53 correspond, the airway 41 is connected and the airflow is ejected.

[0031] During operation, at the initial stage of cleaning, when the airflow nozzle 42 drops to the lower position, the two through holes 53 are in a dislocated blocking state. At this time, the airflow will not blow out, thereby not affecting the spraying of the cleaning liquid. When the movable nozzle 31 rotates to the cleaning end angle position (during the rotation process, the plug 5 and the airflow nozzle 42 rotate relative to each other), the two through holes 53 correspond, the airway 41 is connected, and the airflow is sprayed to achieve the cleaning of the cleaning liquid. Subsequently, the airflow nozzle 42 rises and resets.

[0032] Of course, a reset member 44 (such as a reset spring) is installed inside the airflow nozzle 42 to drive the plug 5 to rotate and reset.

[0033] During the entire cleaning process of the bag tube 01, after the bag body 00 is transferred to the predetermined position, the airflow nozzle 42 descends to the lower state (the plug 5 enters the blocking state), the movable nozzle 31 sprays the cleaning liquid, and then the airflow nozzle 42 drives the movable nozzle 31 to rotate to achieve comprehensive cleaning. After the movable nozzle 31 rotates to the cleaning end angle position, the air channel 41 is opened and the airflow is sprayed. Finally, the airflow nozzle 42 rises and resets.

[0034] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
