Description

Bag making machine valve cut waste recycling device

1. Technical field

The utility model belongs to mechanical equipment, in particular to a bag-making machine valve mouth cutting waste recycler for cement-laminated woven bags.

2. Background technology

Laminated woven bags are widely used for filling cement due to their low cost and good strength. At present, the waste pieces cut off by the bag-making machine that produces laminated woven bags fly everywhere during the production process, especially when making woven bags with larger bags and more complex structures, a large number of large pieces of waste pieces are cut, and the enterprise needs to configure Full-time workers clean and collect the waste pieces flying around. The labor intensity of the workers is high, which not only affects the production environment of the production workshop, but also causes safety accidents when large waste pieces fall on the machine.

3. Contents of the invention

The purpose of the utility model is to provide the market with a cement-laminated woven bag bag-making machine valve port cutting waste recycling device with reasonable structure, convenient operation, and convenient collection of waste pieces.

The technical scheme of the utility model is: it is composed of a frame, a rotating cylinder, a rotating cylinder shaft, a valve opening knife, an upper knife rest, etc., and the two ends of the rotating cylinder shaft are fixedly installed on the two sides of the frame through bearings respectively. One end is provided with a drive wheel, the inner wall of the frame on both sides is provided with the track of the slider, the valve mouth knife is set on the drum, and a pinhole is set on the valve knife, and a steel needle lifting mechanism is arranged below it. It is composed of a steel needle seat, a lifting rod, a lever, a slider, a track and a positioning arm. One end of the lever on both sides is connected with the slider, and is respectively installed in the holes on the two side walls of the drum through the pin shaft, and the other end is provided with a groove. The lifting rods at both ends of the steel needle holder pass through the slot holes and are hinged by the pin shaft. The lifting rods at both ends of the steel needle holder are inserted into the positioning holes of the positioning arm set on the inner wall of the drum, and the three steel needles are evenly installed on the steel needle. The seat corresponds to the three pinholes provided on the valve knife.

The beneficial effects of the utility model are: since a steel needle lifting device driven by a lever is arranged under the valve opening knife, the device is located under the valve opening knife and rotates with the rotating cylinder during the rotation of the drum, and when the upper knife and the valve opening When the knife cuts the material, the change of the curve of the track 7 on the inner wall of the frame on both sides makes the lever act, and the steel needle rises from the needle hole on the knife on the valve port and sticks firmly into the large piece of cut waste to prevent the waste from flying with the wind. , when the upper knife is separated from the valve opening knife, the steel needle descends and retracts into the drum, and the cut large pieces of waste automatically fall into the set waste recycling container under the action of gravity.

Below in conjunction with accompanying drawing, the utility model is further described.

4. Description of drawings

Fig. 1 is a schematic cross-sectional structure diagram of the utility model.

In the figure: 1 is the valve opening knife, 2 is the drum, 3 is the frame, 4 is the shaft of the drum, 5 is the bearing, 6 is the driving wheel, 7 is the track, 8 is the slider, 9 is the lever, 10, 12 Be bearing pin, 11 is slotted hole, and 13 is hole, and 14 is steel needle seat, and 15 is steel needle, and 16 is pinhole, and 17 is elevating rod, and 18 is positioning arm.

5. Specific implementation

As shown in Fig. 1, the existing bag-making machine is improved, three needle holes 15 are set on the valve knife 1, and a steel needle 15 lifting mechanism is set below the valve knife 1. This elevating mechanism is made up of steel needle seat 14, elevating rod 17, lever 9, slider 8, track 7 and positioning arm 18, and one end of lever 9 on both sides is connected with slider 8, and is respectively installed in the rotation through pin 10 movably. In the holes 13 on both sides of the cylinder, the other end is provided with slotted holes 11, and the lifting rods 17 at both ends of the steel needle holder 14 pass through the slotted holes 11 and are hinged through the pin shaft 12, and the lifting rods 17 at both ends of the steel needle holder 14 are inserted into the drum. In the positioning hole of the positioning arm 18 provided on the inner wall, three steel needles 15 are evenly installed on the steel needle seat 14, corresponding to the three needle holes 16 provided on the valve opening knife 1 . The two ends of the drum shaft 4 are respectively fixedly installed on the two side frames 3 through the bearings 5, and one end thereof is provided with a drive wheel 6, and the inner wall on both sides of the frame 3 is provided with a track 7 of a slide block 8, and the track 7 is a special curve. When implementing the utility model, the rotating drum 2 rotates continuously under the action of the driving wheel 6 at the end of the rotating drum shaft 4, and the steel needle 15 arranged in the rotating drum 2 retracts into the bottom of the drum valve opening knife 1 and rotates with the rotating drum. When the upper knife of the material cutting frame meets the valve mouth knife 1, the sliders 8 on both sides change lanes along with the track 7, so that the lever 9 movable on the pin shaft 10 on the two side walls of the drum is pressed down, and the end of the lever 9 passes through The pin shaft 12 makes the elevating rod 17 rise, and the steel needle 15 installed on the steel needle seat 14 on the elevating rod 17 passes through the needle hole 16 of the valve mouth knife, and firmly nails the cut large piece of waste, which is used as the upper knife. After gradually separating from the valve port knife 1, the valve port knife runs downwards, and the steel needle 15 will retract into the drum 2 under the action of the lever 9, and at this time, the nailed waste pieces will automatically fall to the bottom and set waste recycling container. Such a reciprocating cycle realizes the centralized recycling of the cut waste pieces, which can not only reduce the labor intensity of workers, ensure the production environment of the workshop, but also effectively prevent safety accidents. The utility model has the advantages of reasonable structure, convenient operation, environmental protection, cost reduction, etc., and is suitable for popularization and application on bag making machines.
