Description

Technical Field

[0001] The utility model relates to a component on a bag-feeding packaging machine, in particular to a horizontal bag-feeding component of the bag-feeding machine. Background Art

[0002] The bag-feeding packaging machine mainly puts materials into plastic packaging bags for packaging. There are various bagging methods such as rotary bag-feeding machines and vertical bag-feeding machines. Its workstations generally include bag-loading station, bag-entering station, and vacuum sealing station. When packaging larger materials, such as large-sized seafood such as large fish and octopus, large integral materials require packaging bags of correspondingly large specifications. In this way, rotary and vertical bag-feeding structures cannot adapt. The packaging bags need to be transported by conveyor belts for packaging. Bag opening stations, bag-entering stations, bag-sealing stations, etc. can be set along the conveyor belt. How to bag the packaging bags (that is, output large-sized packaging bags in sequence) through the bag opening station, bag-entering station, bag-sealing station and other stations is an urgent problem to be solved. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a horizontal bag feeding component of a bag feeding machine, the purpose of which is to allow the packaging bags to pass through the workstations that need to be operated in sequence after being bagged, thereby effectively improving the packaging efficiency.

[0013] The present invention is described in detail below through examples, which are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention.

[0014] like Figure 1-3As shown, this embodiment discloses a horizontal bag feeding component of a bag feeding machine, including a frame 1, a bag holding conveyor belt 2 is provided on the frame 1, and also includes a packaging bag discharge chute 3 placed above the bag holding conveyor belt 2, the packaging bag discharge chute 3 is composed of a support plate and a side plate, the side plate forms a surrounding groove adapted to the packaging bag, the side plate is mounted on the support plate, a part of the support plate is placed in the surrounding groove, the packaging bag is placed in the packaging bag discharge chute 3, and the side of the packaging bag is dragged by the support plate. A bag outlet is provided below the packaging bag discharge chute 3, and a suction cup 4 movable up and down is provided below the bag outlet. The suction cup 4 is connected to the vacuum pump through an electromagnetic valve. There are four suction cups 4 and they are arranged in a matrix. A suction cup 4 is mounted on a bracket, which is connected to the piston rod of a cylinder 50, so that the four suction cups 4 are driven by the cylinder 50 to extend into the bag outlet to pull the packaging bag out of the packaging bag discharge chute 3. Two slides 5 that can open and close up and down are provided on the side of the bag conveyor belt 2. The two slides 5 are provided with clamping parts 6 corresponding to the packaging bag outlet. The clamping parts 6 include two upper clamping rods 61 and two lower clamping rods 62. The upper clamping rods 61 and the lower clamping rods 62 correspond to each other and are aligned one by one. The upper clamping rod 61 is mounted on the upper slide 5, and the lower clamping rod 62 is mounted on the lower slide 5. The middle hole of the clamping rod (upper clamping rod and lower clamping rod) is connected to the vacuum pump through another solenoid valve.

[0015] The two slides 5 are respectively arranged on the guide rails 7 corresponding to each other, and a rotating shaft 8 is arranged under the frame 1. The rotating shaft 8 is controlled by a servo motor 9 and also includes a rotating arm 10. The end of the rotating shaft 8 is in the middle of the rotating arm 10. The two ends of the rotating arm 10 are respectively connected to the vertical guide rods 20. One of the two vertical guide rods connected by the rotating shaft 8 is connected to one of the guide rails 7, and the other is connected to the other guide rail 7. A vertical guide block is also provided on the frame 1. The two vertical guide rods 20 pass through the corresponding guide holes on the vertical guide block. It also includes a driving mechanism 30 that drives the movement of the slide 5. The driving mechanism 30 can make the slide 5 move laterally along the guide rail 7. The packaging bag clamped by the upper and lower clamping rods on the slide 5 can be moved out and reaches the corresponding operating station, so that the output of the packaging bag is more reliable and stable.

[0016] The driving mechanism 30 includes a deflection shaft 301, which is driven by a transmission servo motor 302. The eccentric rotation generated by the rotation of the deflection shaft 301 drives the two rocker arms 303 to swing back and forth. A transmission link 304 corresponding to the slide 5 is also provided. The transmission link 304 is transmission-connected to the corresponding slide 5. One end of the rocker arm 303 is connected to the deflection shaft 301 through a bearing sleeve. The rocker arm 303 corresponds to the transmission link 304 one-to-one. The other end of the rocker arm 303 is rotatably connected to the transmission link 304. The rocker arms 303 are connected by a straight rod 305 to ensure that the two slides 5 move in unison. In this way, the upper and lower clamping rods on the two slides 5 can clamp the packaging bag and move back and forth at a certain distance, so that the packaging bag adsorbed by the suction cup 4 can be clamped and moved out of the bag and then released for subsequent operations such as adding materials into the bag and sealing the bag. After releasing, the clamping is reset and the packaging bag adsorbed by the suction cup 4 is clamped and output again, thereby completing the bagging task.

[0017] The driving mechanism 30 can also be a linear motion module (the linear motion module structure is a displacement linear guide rail, on which a slider sliding along the linear guide rail is provided, and a belt arranged around it is also provided, and the belt arranged around it is driven by a servo motor, and the slider is connected to the belt, and the slider of the linear motion module is connected to the slide 5), so that the slide 5 can be directly driven to move linearly so that the upper and lower clamping rods on the two slides 5 can clamp the packaging bag and move it to any position.

[0018] Of course, the horizontal bag loading component needs to rely on a control system, which controls various solenoid valves, motors and other components through programming to accurately complete the suction cup 4 bag extraction action and the upper and lower clamping rod bag clamping and transfer action.

[0019] By adopting the above technical solution, the stacked large-size packaging bags are stacked in the packaging bag discharge trough 3, and the packaging bag at the bottom is sucked by the suction cup 4 and then pulled out from the bottom opening of the packaging bag discharge trough 3, and the bag body of the packaging bag is supported on the conveyor belt, and the bag opening position of the packaging bag is clamped by the upper and lower clamping rods and brought out by the slide 5. Since the clamping rod is connected to the vacuum pump, the upper and lower clamping rods can cooperate with the slide 5 to open or close the bag opening. In this way, after the packaging bag is loaded, it passes through the work station where operation is required, thereby effectively improving the packaging efficiency.
