Description

Rotary bag support device

technical field

The utility model relates to the technical field of bag packing machines, in particular to a device for opening packing bags.

Background technique

In the modern packaging industry, most metropolises use bagging machines for product packaging. Before packaging, the packaging bags used for packaging are usually stacked together. When packaging, they are sucked down one by one by the suction bag device, and then the bags are opened, stretched, filled and sealed. The bag support device is used to open the packaging bag in order to fill the packaging bag. The traditional bag supporting device works with a single station, and the bag filling process needs to be completed after the bag supporting process is completed. The bag supporting and bag filling processes are carried out alternately, resulting in low production efficiency of the bag packing machine.

Utility model content

The technical problem to be solved by the utility model is to provide a rotary bag supporting device which can improve the production efficiency of the bag packing machine.

The technical solution adopted to solve the above technical problems: a rotary bag supporting device, characterized in that it includes a turret driven by the first driving device, and at least two charging materials are evenly arranged on the turret around its rotation circumference. Channel, the two sides of the charging channel are respectively hinged with tongues that open and close in opposite directions. A spring is installed between the tongue and the turret to maintain its opening or closing tendency. The moving mechanism is opened or closed by the elastic force of the spring, and the moving mechanism adopts the second driving device to drive it to expand and contract.

Further, the tongue is fixed on a swinging piece, and the swinging piece is hinged with the turret; the spring adopts a tension spring that keeps the opening tendency of the tongue; the moving mechanism includes a push rod that can pass through the turret, One end of the push rod can swing against the swing member as a tongue to close, and the other end is fixed on the mounting plate, and the mounting plate is drivingly connected with the second driving device.

Preferably, the first driving device adopts a rotary air/oil cylinder. The second driving device adopts an air/oil cylinder. Or the first driving device and the second driving device are driven by a motor through a transmission mechanism.

The beneficial effects brought by the adoption of the utility model: the utility model adopts at least double-station bag support, the bag support station is arranged on the turret, and as the turret rotates, the bag support station is between the bag opening station and the loading Switch between stations, when it is turned to the bag opening station, the bag opening device will suck the opened packaging bag and put it on the support tongue of the bag support device to open the packaging bag, and when it is turned to the charging station, it will be opened by the bag opening device. The feeding device pushes the material from the charging channel of the bag supporting device into the opened packaging bag. Therefore, with the rotation of the turret, there is always a bag stretching station that is turned to the bag opening station to carry out the bagging and bagging process, and the other bag stretching station is just turned to the opposite to the charging station for loading materials. process. The two processes of bagging and bagging can be completed simultaneously by two bagging stations respectively, thus greatly improving the production efficiency of the bagging machine.

Fig. 1 is a structural schematic diagram of the rotary bag supporting device of the bag packing machine of the present invention.

Detailed ways

As shown in Fig. 1, a kind of rotary bag supporting device comprises the turret 2 driven by the first driving device 1 to rotate, the turret 2 is evenly arranged at least two charging channels 2.1 on its rotation circumference, 2. The two sides of 1 are respectively hinged with tongues 3 that open and close in opposite directions. A spring 4 is installed between the tongue 3 and the turret 2 to maintain its opening or closing tendency. 3. A moving mechanism 5 that is opened or closed against the elastic force of the spring 4. The moving mechanism 5 uses a second driving device 6 to drive it to expand and contract. In this embodiment, the turret 2 is set to rotate around the horizontal shaft 7 , the horizontal shaft 7 is installed on the frame 8 , and the first driving device 1 is drivingly connected to the horizontal shaft 7 . There are two charging passages 2.1, which are evenly arranged at both ends of the turret 2, and the charging passages 2.1 are arranged to extend axially along the horizontal axis 7. The spring 3 is set to keep the opening trend of the tongue 3. Correspondingly, the moving mechanism 5 is set to push the tongue 3 to close when stretching out towards the tongue 3, and the moving mechanism 5 is located corresponding to the bag opening station. A charging channel 2.1 and the supporting tongues 3 hinged on both sides constitute a bag supporting station. When working, the first driving device 1 drives the turret 2 to rotate, so that one of the bag supporting stations is turned to the bag opening station. At this time, the second driving device 6 drives the moving mechanism 5 to stretch out toward the tongue, pushes the tongue 3 on both sides of the bag stretching station to close, and then the bag opening device wraps the opened bag on the two tongues. 3, then the second driving device 6 drives the moving mechanism 5 to retract, the two tongues 3 are opened under the action of the spring 4, and the packaging bag is stretched, and the first driving device 1 drives the turret 2 to continue to rotate, so that the package is supported The bag supporting station is turned to the opposite loading station, and the material is pushed into the packaging bag from the charging channel 2.1 by the charging device. The bag device is inserted into the packaging bag, therefore, every time the turret 2 rotates 180°, there is a bag stretching station which is directly opposite to the bag opening station and the charging station, and the bag stretching and charging work can be carried out simultaneously, thus greatly improving the efficiency of the bagging process. installed productivity.

Furthermore, in order to make the structure of the rotary bag supporting device of the present utility model more reasonable and facilitate processing and assembly, the support tongue 3 is fixed on a swinging member 9 , which is hinged to the turret 2 . The spring 4 that keeps the opening tendency of the stay tongue 3 adopts a tension spring. The moving mechanism 5 includes a push rod 5.1 that can pass through the turret 2. One end of the push rod 5.1 can swing against the swing member 9 as the tongue 3 is closed, and the other end is fixed on the mounting plate 5.2. The mounting plate 5.2 It is drivingly connected to the second drive device 6 . Concretely, the swinging member 9 can be set into a corner code shape, with its corners and corners as the hinge shaft 10 hinged with the turret 2, its one side plate is fixed with the support tongue 3, and the other side plate can be offset against the push rod 5.1, and the spring 4 is connected between the side plate of the fixed tongue 3 of the swing member 9 and the turret 2.

In this embodiment, the first driving device 1 may be a rotary air cylinder or a rotary oil cylinder. The second driving device 6 can be a linear cylinder or a linear oil cylinder. Of course, the first driving device 1 and the second driving device 6 can be driven by a motor through a transmission mechanism in addition to the above-mentioned air/oil cylinder, which is a conventional choice for those skilled in the art and will not be described in detail here.
