Description

Technical Field

[0001] This utility model relates to a bag feeding device for delivering packaging bags to a bag-feeding packaging equipment. Background Technology

[0002] Currently, there are several shortcomings in feeding packaging bags to bag feeding equipment. One bag can only be transported to the bag feeding position after the bag at the bag exit position has been grabbed by the clamp of the bag feeder. The bag feeding speed is slow, which affects the packaging needs of the bag feeder. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a bag feeding device that can improve the bag feeding speed and better meet the packaging needs of bag feeding machines.

[0004] This utility model is implemented through the following technical solution: A bag feeding device for improving bag feeding speed is characterized by: including a conveyor table, with multiple conveyor belts spaced a certain distance apart in the middle of the conveyor table, the conveyor belts being driven by a conveyor motor, the conveyor table having a bag receiving position, a bag waiting position, and a bag exit position, the bag waiting position having a bag blocking component, the bag blocking component being movably configured, the bag exit position having a bag blocking plate, and a bag mouth suction nozzle and a bag tail suction nozzle being movably configured above the bag exit position, respectively used to suck up and lift the beginning and end of the packaging bag at the bag exit position.

[0005] The movement of the bag mouth suction nozzle is driven by the bag mouth suction nozzle cylinder, and the movement of the bag tail suction nozzle is driven by the bag tail suction nozzle cylinder.

[0006] The movement of the bag mouth suction nozzle is driven by the bag mouth suction nozzle cylinder through a four-bar linkage.

[0007] The movement of the bag-blocking component is driven by the bag-blocking component cylinder.

[0008] The head of the bag-blocking component is a hook. When the bag is blocked, the hook enters the gap between two adjacent conveyor belts.

[0009] After adopting the above technical solution, the bag outlet position during operation is equipped with a bag mouth suction nozzle and a bag tail suction nozzle working simultaneously to lift the entire packaging bag. As a result, before the bag is grabbed by the bag feeder, the bag outlet position has reserved space to allow the next packaging bag to arrive at the bag outlet position in advance, thereby improving the bag feeding speed and better meeting the packaging needs of the bag feeder.

[0012] As shown in the figure, the bag feeding device of this utility model for improving bag feeding speed includes a conveyor platform 30. Multiple circular conveyor belts 31 spaced at certain intervals are arranged in the middle of the conveyor platform 30. The circular conveyor belts 31 are driven by a conveyor motor. The conveyor platform 30 has a bag receiving position, a bag waiting position, and a bag discharging position. The bag receiving position is used to receive packaging bags from the bag transfer device. The bag waiting position has a bag blocking member 32, which is movably arranged. The movement of the bag blocking member 32 is pushed by a bag blocking member cylinder 37. The head of the bag blocking member 32 is a hook. In the bag blocking state, the hook enters the gap between two adjacent circular conveyor belts 31. The bag is blocked; a bag blocking plate 34 is fixedly installed at the bag exit position, and a bag mouth suction nozzle 38 and a bag tail suction nozzle 39 are movably installed above the bag exit position. The bag mouth suction nozzle 38 is used to suck up and lift the first end of the packaging bag at the bag exit position, and the bag tail suction nozzle 39 is used to suck up and lift the last end of the packaging bag at the bag exit position, so that the bag exit position has reserved space for the next packaging bag to arrive at the bag exit position in advance before the bag is grabbed by the clamp of the bag feeding machine. The movement of the bag mouth suction nozzle 38 is driven by the bag mouth suction nozzle cylinder 36 through the four-bar linkage 35, and the movement of the bag tail suction nozzle 39 is driven by the bag tail suction nozzle cylinder 33.

[0013] The present invention works as follows: When the packaging bag is delivered to the receiving position of the conveyor 30, the circular conveyor belt 31 conveys the packaging bag. The packaging bag is limited by the bag baffle 34 at the bag exit position. The subsequent packaging bags are temporarily blocked by the bag baffle 32 at the bag baffle position. At this time, the bag mouth suction nozzle 38 and the bag tail suction nozzle 39 work to suck up the bag mouth and bag tail of the packaging bag at the bag exit position, respectively, so that the entire packaging bag is lifted away from the bag exit position and waits to be grabbed by the clamp of the bag feeder. Since the bag exit position has reserved space at this time, the bag baffle cylinder 37 pushes the front end of the bag baffle 32 to lift. Thus, the next packaging bag blocked by the bag baffle 32 can reach the bag exit position in advance before the previous packaging bag is grabbed by the clamp of the bag feeder. By repeating the above actions, the bag feeding work with increased bag feeding speed can be completed.
