Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and examples.
The invention provides a special bag body, as shown in figure 4, the bag body is composed of a plurality of water bags, and the side edges of the water bags are connected in sequence one by one, so that the water bags can be continuously supplied to filling equipment. Referring to fig. 3, the water bag 11 has a water inlet 13, and the water inlet 13 should have a one-way water injection function, that is, only allow water to enter the water bag. Referring to fig. 3, in this embodiment, the water inlet 13 extends into the water bag 11 to form two sealing layers, such as the upper sealing layer 12. When water is injected, the two sealing layers are opened to enable water to enter the water bag, the water injection is completed, and the two sealing layers are naturally attached to form a sealing structure under the extrusion of the water, so that the water is prevented from flowing out of the water bag.
As shown in fig. 1, the bag body 2 is wound around the bag wheel 9 in advance, passes through the tension mechanism 1 (composed of two tension rollers), and is introduced into the conveying mechanism. The circumferential surface of the supporting wheel 6 of the conveying mechanism is sequentially provided with a plurality of bag grooves in an annular mode, the bag grooves are used for containing water bags filled with water, the bag grooves are conveyed after the bag grooves are rotated, and the water bags can continuously enter the bag grooves to form continuous supply of the water bags. The guide wheel 5 is matched with the supporting wheel 6, the structure of the guide wheel 5 is similar to that of the supporting wheel 6, and a plurality of bag grooves are formed in the peripheral surface of the guide wheel 5, so that when the supporting wheel 6 and the guide wheel 5 rotate, the bag grooves in the peripheral surface are sequentially buckled, and the water bag after being filled with water can be conveyed smoothly.
Still taking fig. 1 as an example, a cutting wheel 7 is arranged at the outlet end of the guide wheel 5, a plurality of bag slots arranged in sequence are also formed on the peripheral surface of the cutting wheel 7 like the guide wheel, the cutting wheel 7 is matched with the guide wheel 5, so that the guide wheel and the bag slots on the cutting wheel are buckled in sequence, the water bag is continuously conveyed backwards, and meanwhile, the water bag conveyed to the position is separated from the bag body and is delivered into the picking groove 8. Referring to fig. 5, the cutting wheel 7 and the guide wheel 5 are combined together, and in order to smoothly cut off the connection between the water bags, a protruded blade is formed on the groove wall of the groove of the cutting wheel, and when the groove wall of the cutting wheel and the groove wall of the guide wheel meet, the blade cuts off the connection part of the water bags, so that the water bags are separated from the bag body. In order to avoid damage to the blades, grooves compatible with the blades are formed on the end faces of the groove walls of the guide wheels, into which the blades just engage when the water bag is being split (see fig. 5).
As shown in fig. 1 and 2, the filling means is mounted at the front end of the conveying means, and the filling means has a movable water filling nozzle 10, and the water filling nozzle 10 fills the water bag. In order to enable the water bag after water filling to fall into the bag groove, the water filling target position of the water bag for water filling is preferably arranged above the bag groove, the water filling nozzle 10 is arranged in front of the water filling target position, therefore, after the water bag to be filled moves to the water filling target position, the water filling nozzle 10 extends into a water inlet of the water bag to fill water, in order to avoid water seepage during water filling, two sealing pressing blocks, such as the sealing pressing block 3 above, are arranged at the upper and lower positions of the water inlet, grooves are formed on the opposite surfaces of the sealing pressing blocks, the two grooves are matched with the water inlet, and after the two grooves are buckled, the inner circumferential surface of the water inlet can be only extruded on the circumferential surface of the water filling nozzle, so. The two sealing pressing blocks are connected through a screw, the distance between the sealing pressing blocks is adjusted through rotating the screw, a motor 4 can be installed above the screw, and the motor 4 controls the screw to move. The invention also provides an automatic filling method of the automatic filling equipment for the bagged water, which comprises the following steps:
preassembling the bag body on the conveying mechanism;
three rollers of the conveying mechanism rotate to enable a water bag to be filled on the bag body to move to a target position, namely, the water bag enters a bag groove of the supporting wheel, namely, the target position for filling water;
the water filling nozzle feeds water to a water inlet of the water bag at the target position, and after the water filling nozzle is sealed with the water inlet, the water filling nozzle fills water into the water bag at the target position;
after the water bag at the target position is filled with water, the three rollers rotate to pull the bag body, so that the other water bag to be filled on the bag body enters the target position, and meanwhile, the guide wheel and the cutting wheel cut the head end of the bag body to form the filled water bag, so that the filled water bag is separated from the bag body and falls into a picking position.
For further improvement, a shell can be arranged outside the filling machine, the shell is used for sealing the filling mechanism and the conveying mechanism to avoid artificial damage to the equipment, a two-dimensional code is pasted outside the shell, the two-dimensional code is scanned by a mobile phone to obtain information of the equipment, the information is sent to a remote control system, the remote control system sends instructions to the controller of the filling machine according to the received information, and the controller controls the actions of the conveying mechanism, the filling mechanism and the like to throw out the filled water bags, so that the aim of remote control is fulfilled.
