DETAILED DESCRIPTION

[0028] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with 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 intended to limit the present invention.

[0029] See also Figure 2 The present invention provides a bag tube opening cleaning structure, which includes a material transmission guide rail 1 for supporting the bag body, a material transmission component 2 for driving the bag body 00 along the material transmission guide rail 1, a cleaning liquid spraying component 3 provided on one side of the material transmission guide rail 1, and a cleaning liquid cleaning component for blowing off the cleaning liquid remaining at the bag tube opening 01;

[0030] The material transfer guide 1 utilizes a dual-slide rail structure. When the bag body 00 is in a supported state, the latching protrusion 02 at the bag tube opening 01 engages the material transfer guide 1 (the bag tube opening 01 is positioned in the transfer space in the middle of the dual-slide rail structure), and the material transfer component 2 drives the bag body 00 to move. In this embodiment, the material transfer component 2 is a turntable structure (driven by a servo motor during operation to intermittently rotate at equal angles). Its outer edge is provided with at least one latching slot 21 for receiving the bag tube opening 01. When the material transfer component 2 is in a rotating state, the latching slot 21 pushes the bag tube opening 01, thereby moving the bag body 00. Accordingly, the material transfer guide 1 is a curved guide rail with a curvature consistent with that of the outer edge of the material transfer component 2. Of course, the material transfer guide 1 may also utilize a straight guide rail structure, with the corresponding material transfer component 2 utilizing a drive structure compatible with the straight guide rail structure.

[0031] See also 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 tube mouth 01; the movable nozzle 31 is connected to the supplier (liquid pump) through a hose; during the rotation process of the movable nozzle 31 (the rotation angle can be set as needed), its spraying direction is always toward the bag tube mouth 01; during the rotation process of the movable nozzle 31, the cleaning liquid is sprayed to achieve comprehensive cleaning of the outer wall of the bag tube mouth 01.

[0032] See also Figure 2 andFigure 3 The cleaning liquid cleaning assembly comprises an air channel 41 towards the bag spout 01 and a gas supply component connected thereto; specifically, the upper portion of the cleaning liquid spraying assembly 3 is provided with an air flow nozzle 42, and the air flow nozzle 42 is connected to the gas supply component. After the movable nozzle 31 is cleaned, the cleaning liquid cleaning assembly blows air flow to the outer wall of the bag spout 01, and the cleaning liquid remaining on the outer wall of the bag spout 01 is blown down by the air flow, thereby avoiding secondary pollution caused by the remaining cleaning liquid.

[0033] Preferably, the opening of the air flow nozzle 42 of the present application is provided with a plug 5 for plugging the opening of the bag spout 01 during the cleaning process; the air flow nozzle 42 is driven by a lifting component to approach or move away from the position of the bag spout 01 (the air flow nozzle 42 is vertically lifted), so as to drive the plugging or unplugging work of the plug 5; and the air channel 41 is arranged at the periphery of the plug 5, and the plug 5 does not affect the circulation of the air flow.

[0034] In the present embodiment, in order to improve the integration of the device, the rotating work of the movable nozzle 31 is driven by the air flow nozzle 42; specifically, the driving member is a lever 43 arranged on the side wall of the air flow nozzle 42, and the end of the lever 43 is connected to the movable nozzle 31. When the air flow nozzle 42 is driven by a lifting component to approach the position of the bag spout 01 (the plug 5 enters the plugging state), then it is rotated to drive the rotating work of the movable nozzle 31.

[0035] In the first embodiment, the connecting end of the lever 43 is directly fixed to the movable nozzle 31.

[0036] Referring to Figure 2 , Figure 3 , Figure 7 , Figure 8 and Figure 9In the embodiment shown in the figure, to avoid the excessive rotation of the airflow nozzle 42 causing the cleaning liquid supply hose connected with the movable nozzle 31 to be wound around the equipment components, thereby affecting the normal operation of the equipment, a set of cleaning liquid spraying assemblies 3 are arranged on both sides of the material conveying guide rail 1, so that each set of movable nozzles 31 only needs to be rotated by approximately 180 degrees during the cleaning process. Meanwhile, the cleaning liquid spraying assembly 3 further comprises a nozzle support 32 installed on the rack and used for supporting the movable nozzle 31; the nozzle support 32 is provided with a placement platform at the end, and 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 through a limiting connecting piece. The limiting connecting piece can be a straight spring, or considering that the stretching length of the straight spring is limited, in the embodiment, the limiting connecting piece comprises a flexible connecting piece connecting the nozzle support 32 and the movable nozzle 31 and a tensioning assembly for tensioning the flexible connecting piece to reduce the distance between the nozzle support 32 and the movable nozzle 31 when the driving member is rotated to reset. The flexible connecting piece is a pull rope 61, and the tensioning assembly is a tensioning rotating wheel 62 (a torsional spring is installed inside the tensioning rotating wheel 62 to provide the rotating reset effect), and in the initial state, the pull rope is wound on the tensioning rotating wheel.

[0037] The lifting component driving the lifting work of the airflow nozzle 42 can be a pneumatic cylinder, and the mechanism driving the rotation of the airflow nozzle 42 comprises a first meshing disc arranged on the piston rod of the pneumatic cylinder, a second meshing disc capable of being meshed with the first meshing disc, and a motor driving the rotation of the second meshing disc. After the pneumatic cylinder drives the airflow nozzle 42 to descend to the predetermined position, the first meshing disc will be meshed with the second meshing disc, and the motor can drive the airflow nozzle 42 to rotate and work.

[0038] In addition, in the present application, the airflow nozzle 42 in the uncleaned state is in the upper position (the plug 5 is away from the position of the bag pipe opening 01), so that there is a distance between the movable nozzle 31 and the nozzle support 32, causing the torsional spring or the straight spring to be always in the stretched state. To ensure the service life of the torsional spring or the straight spring, a slot 311 is formed in the side wall of the movable nozzle 31 for the convenience of inserting the lever 43, and a positioning protrusion 312 is arranged on the connecting end of the lever 43 in the slot 311 for stabilizing the connection stability of the lever 43 and the movable nozzle 31.

[0039] After the airflow nozzle 42 descends to the lower position (the plug 5 enters the plugging state), the lever 43 is inserted into the slot 311 of the movable nozzle 31, and the positioning effect of the positioning protrusion 312 is used to stabilize the rotating state of the movable nozzle 31 driven by the lever 43.

[0040] Referring to Figure 3 , Figure 4 and Figure 5Meanwhile, in order to avoid the situation that the air flow nozzle 42 rotates to cause the plug 5 to be not tightly sealed (the rotating plug 5 can have a gap with the bag pipe opening 01) and to avoid the situation that the bag body 00 rotates to cause the clamping with the material conveying rail 1 to be unstable, and to ensure that the air flow blowing process is stably performed after the cleaning is completed, the plug 5 is rotatably arranged in the air flow nozzle 42; the air flow nozzle 42 and the plug 5 have an air flow sealing structure for sealing the air flow, which comprises a first sealing plate 51 arranged in the air flow nozzle 42 and a second sealing plate 52 arranged at the end of the plug 5; the two plates are both provided with a through hole 53, when the air flow nozzle 42 and the plug 5 are relatively rotated, the two through holes 53 are corresponded, the air channel 41 is communicated, and the air flow is blown out.

[0041] In the working process, in the initial cleaning stage, when the air flow nozzle 42 is lowered to the lower position, the two through holes 53 are in the sealing state, at this time, the air flow cannot be blown out, so as not to affect the blowing out of the cleaning liquid. When the movable nozzle 31 is rotated to the final cleaning angle position (in the rotating process, the plug 5 and the air flow nozzle 42 are relatively rotated), the two through holes 53 are corresponded, the air channel 41 is communicated, the air flow is blown out, and the cleaning liquid is removed. Subsequently, the air flow nozzle 42 is raised to reset.

[0042] Of course, the air flow nozzle 42 is internally provided with a reset member 44 (a reset spring) for driving the plug 5 to rotate and reset.

[0043] In the whole cleaning process of the bag pipe opening 01, after the bag body 00 is conveyed to the predetermined position, the air flow nozzle 42 is lowered to the lower position (the plug 5 is in the sealing state), the movable nozzle 31 blows out the cleaning liquid, and then the air flow nozzle 42 drives the movable nozzle 31 to rotate to realize the overall cleaning. After the movable nozzle 31 is rotated to the final cleaning angle position, the air channel 41 is communicated, the air flow is blown out. Finally, the air flow nozzle 42 is raised to reset.

[0044] Of course, the present application can also have other various embodiments, and those skilled in the art can make various corresponding changes and modifications according to the present application without departing from the spirit and essence of the present application, but these corresponding changes and modifications should all belong to the protection scope of the claims attached to the present application.
