[0027] The bag supply device structure of the strapping packaging machine provided in the embodiment of the present invention is as follows: Figures 1 to 5 As shown, it includes a frame 1, and a bag placing platform 2 and a bag taking mechanism 3 installed on the frame 1; the bag placing platform 2 is used to stack packaging bags, and a bag taking port 21 is provided at one end of the bag placing platform 2; the bag taking mechanism 3 is used to take packaging bags from the bag taking port 21; when performing cable tie packaging, the stacked packaging bags are placed on the bag placing platform 2, and the bag taking mechanism 3 takes one packaging bag at a time from the bag taking port 21, and the taken packaging bags are provided to the cable tie bagging mechanism of the packaging machine for the cable tie bagging process. This embodiment does not involve the cable tie bagging mechanism and other mechanical structures, which will not be described in detail.

[0028] In this embodiment, a cylinder 11 is provided on the frame 1 above the bag placing platform 2, and a pressure plate 12 parallel to the bag placing platform 2 is fixed to the output end of the cylinder 11. The pressure plate 12 is driven by the cylinder 11 to move up and down, and a guide bar 13 is provided on the pressure plate 12 along the up and down directions. A rotary encoder 14 connected to the control system of the cable tie packaging machine is installed on the frame 1, and a guide wheel 15 is fixed to the input end of the rotary encoder 14. The outer periphery of the guide wheel 15 contacts the side of the guide bar 13, and the guide bar 13 drives the guide wheel 15 to rotate when it moves up and down. In actual During operation, a stack of packaging bags is placed on the bag placement platform 2. Cylinder 11 controls the pressure plate 12 to continuously press the bags downward. As the bag removal mechanism 3 removes the bags from the bottom, the thickness of the stacked bags gradually decreases, and the pressure plate 12 gradually moves downward. Simultaneously, the downward movement of the guide bar 13 drives the guide wheel 15 to rotate, causing the rotary encoder 14 to transmit a signal to the control system of the cable tie packaging machine. This facilitates automatic monitoring of the remaining number of packaging bags on the bag placement platform 2. When the number of packaging bags is insufficient, they can be replenished in a timely manner, thereby improving the automation level and operating efficiency of the cable tie packaging machine. In actual operation, an alarm can also be installed on the frame 1 and connected to the control system. When it detects that the number of packaging bags on the bag placement platform 2 is insufficient, the control system controls the alarm to issue an alarm signal to the outside, so that the staff can be aware of it and replenish the packaging bags in a timely manner. The alarm can be a warning light, a buzzer, etc.

[0029] like Figure 1 、 Figure 3 and Figure 4As shown, a swing plate 22 is provided at the bag taking port 21, and the swing plate 22 can be connected to the bag placing platform 2 through a hinge. A driving mechanism is provided at the bottom of the bag placing platform 2, and the driving mechanism drives the swing plate 22 to swing up and down, and when the swing plate 22 rotates to the highest point, it is level with the bag placing platform 2. When the packaging bag is placed on the bag placing platform 2, one end is correspondingly above the bag taking port 21, and a bag suction unit 23 is provided on the swing plate 22. In this way, the bag suction unit 23 sucks the bottom packaging bag, and when the driving mechanism drives the swing plate 22 to swing downward, the corresponding end of the packaging bag is driven to droop, so that the bag taking mechanism 3 can take away the packaging bag. After the bag taking mechanism 3 takes away the packaging bag, the driving mechanism drives the swing plate 22 to move upward to suck the next packaging bag.

[0030] In some embodiments, as Figure 3 and Figure 4 As shown, the bag suction unit 23 includes a mounting block 231 fixed to the swing plate 22 and a plurality of suction cups 232 fixed to the mounting block 231. The suction cups 232 are connected to the vacuum device via pipelines. Avoidance holes are provided on the swing plate 22 at positions corresponding to the suction cups 232, so that the suction cups 232 can effectively absorb the packaging bags. When the vacuum device is evacuated, the suction cups 232 hold the packaging bags. The bag suction unit 23 has a simple structure and is easy to assemble. The mounting block 231 is provided with an air passage, and the suction cups 232 are fixed to the mounting block 231 and communicate with the air passage. The mounting block 231 is provided with a pipeline interface, and the pipeline is connected to the pipeline interface. When installing the bag suction unit 233, the suction cups 232 are first mounted on the mounting block 231, and then the mounting block 231 is fixed to the swing plate 22, which facilitates the installation of the bag suction unit 23.

[0031] In some embodiments, as Figure 4 As shown, the driving mechanism includes a cylinder 24, a hinge seat 1 25 fixed to the bottom of the bag placing platform 2 or the frame 1, and a hinge seat 26 fixed to the bottom of the swing plate 22. The two ends of the cylinder 24 are respectively hinged to the hinge seat 1 25 and the hinge seat 2 26, so that the cylinder 24 can be flexibly connected to the hinge seat 1 25 and the hinge seat 2 26, and the swing plate 22 is driven to swing up and down through the extension and contraction of the cylinder 24.

[0032] In some embodiments, as Figure 1 As shown, in order to effectively support the packaging bags placed on the bag placement platform 2 and prevent the packaging bags from collapsing downward at the bag removal port 21, support laps 27 are provided on both sides of the bag removal port 21 to support the edges of the packaging bags. After the bottom packaging bag is sucked by the bag suction unit 23, the edge of the packaging bag is pulled away from the support laps 27 when the swing plate 22 swings downward.

[0033] In some embodiments, as Figure 1 As shown, relatively set limiting side plates 28 are fixed on the bag placing platform 2, and a bag placing area 29 is formed above the bag placing platform 2 between the relatively limiting side plates 28. When placing packaging bags on the bag placing platform 2, the packaging bags are placed in the bag placing area. The limiting side plates 28 can limit the packaging bags to prevent them from being scattered. In order to facilitate the placement of packaging bags in the bag placing area 29, the upper ends of the limiting side plates 28 are bent outward to form an inclined upward folding edge 281, which can play a guiding role; the supporting lap 27 is fixed to the bottom of the limiting side plate 28.

[0034] In some embodiments, as Figure 2 When the bag is taken out, the clamping cylinder 33 is moved to the swing plate 22 by the rotating cylinder 31, and the clamping cylinder 33 is controlled by the clamping cylinder 33 to clamp the edge of the bag. The clamping cylinder 33 is then driven to move to the bag filling mechanism by the rotating cylinder 31. During the activity of the clamping cylinder 33, the position of the clamping cylinder 33 can be changed by the telescopic cylinder 32 to better meet the needs of use. The above-mentioned bag taking mechanism 3 has a relatively simple structure and stable operation. The clamping cylinder 33 can adopt the finger cylinder commonly used on the market.

[0035] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
