[0002] In the modern packaging industry, the production and transportation efficiency of paper bags directly affects the operational efficiency of the entire supply chain. Traditional paper bag packaging and palletizing processes usually rely on manual operation or simple mechanical equipment, which has problems such as high labor intensity, low efficiency and potential safety hazards. With the continuous improvement of industrial automation, the market demand for packaging equipment is growing, especially in the batch palletizing and packaging of paper bags, which urgently needs an efficient, flexible and safe solution.

[0003] The existing single-arm robotic arm is prone to insufficient stability during the grasping and handling process, especially when packing at high places, which can easily cause the paper bags to fall over or be stacked unsteadily. Secondly, traditional palletizing and packaging equipment often requires a large space to move during operation and cannot flexibly adapt to different production environments. In addition, the existing equipment often uses a complex transmission structure when performing opening and closing actions, which makes equipment maintenance difficult and the failure rate increases.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances. Example

[0030] The utility model provides a double-arm opening and closing driving connecting rod mechanism for batch stacking and packaging of paper bags. Figures 1 to 4 , including a mounting base 1; an opening and closing component 2, which is arranged on one side of the mounting base 1 and is used to transport the stacked paper bags to a high place for packaging, and return to the original position after opening and closing to bypass the packaging place; a power component 3, which includes a first driving member 301 arranged on one side of the mounting base 1, and a second driving member 302 arranged on one side of the opening and closing component 2.

[0031] The mounting seat 1 includes a first connection hole 101, second connection holes 102 arranged on both sides of the first connection hole 101; and an adjustment platform 103 arranged above the mounting seat 1; the opening and closing assembly 2 includes a middle connection plate 201, a first tail connection plate 202 arranged on one side of the middle connection plate 201, a second tail connection plate 203 arranged on the other side of the middle connection plate 201, a connecting piece 204 arranged on one side of the first tail connection plate 202 and the second tail connection plate 203, and a swing arm 205 arranged above the connecting piece 204, and an opening and closing plate 206 arranged at one end of the swing arm 205; the connecting member 204 includes a first pin hole 204a, and a second pin hole 204b arranged below the first pin hole 204a; the middle connecting plate 201 is connected to the first connecting hole 101 through an axle pin; the middle connecting plate 201 is connected to the first tail connecting plate 202 and the second tail connecting plate 203 through an axle pin; the tail connecting plate 202 is connected to the second pin hole 204b through an axle pin; the second connecting hole 102 is connected to the first pin hole 204a through an axle pin.

[0032] The first driving member 301 is a driving motor, which is fixedly mounted at the bottom of the mounting base 1 and is used to lift the stacked paper bags to a high place for packaging; the second driving member 302 includes a cylinder 302a and a cylinder arm 302b arranged on one side of the cylinder 302a; the cylinder arm 302b is connected to the second tail connecting plate 203 through a crank shaft 302c; the cylinder 302a and the one side swing arm 205 are installed through a hinge bearing 302d.

[0033] It should be noted that the second connection hole 102 and the first connection hole 101 of the mounting seat 1 are respectively facing the two sides of the opening and closing component 2, and are connected by a pin shaft. Sliding bearings are arranged between the pin shafts to reduce friction. In other words, the second connection hole 102 and the first connection hole 101 of the mounting seat 1 are in a state of clamping the opening and closing component 2, which can reduce the vibration amplitude when the swing arm is opened and closed. The position where the middle connecting plate 204 and the first connecting hole 101 are connected by the shaft pin is located at the center of the middle connecting plate 204, and is symmetrical on both sides.

[0034] Preferably, the paper bags are sent to the top of the opening and closing plate 206 by a conveyor belt. At this time, the opening and closing plate 206 is closed and can stably support a sufficient number of paper bags. The movement mode of this mechanism consists of two parts. The first part is that the first driving member 301 drives the device as a whole to rise. The first driving member 301 is composed of a screw rod and a servo motor. The servo motor drives the screw rod to drive the mounting base 1 to support the lifting of the overall structure, so that the opening and closing plate 206 drives the paper bags above to rise and send them to the high packaging area for packaging.

[0035] Preferably, the second driving member is driven by the cylinder 302a through a series of connecting rods to drive the swing arm 205 to drive the opening and closing plate 206 to open and close, so that the opening and closing plate 206 bypasses the obstacle and completes the reset.

[0036] The specific process is as follows: in this connecting rod mechanism, the mounting seat 1 is fixed and its position remains constant. The fixed axis is the central axis located at the first pin hole 204a and the central axis located at the first connecting hole 101. When the cylinder 302a inhales or exhausts air through the cylinder hole, the cylinder arm 302b will extend out or retract into the cylinder 302a. Figure 1 The cylinder arm 302b is shown in a fully extended state. Figure 4 The figure shows the state where the cylinder arm 302b is retracted at one end. When retracted, the crank shaft 302c rotates around the second pin hole 204b. At the same time, since the positions of the middle connecting plate 301 and the mounting base 1 are relatively fixed, the mounting base 1 as a whole will vertically slide and adjust its position on the adjustment platform 103 to adapt to the retraction of the cylinder arm 302b. At this time, the opening and closing plate 206 will be separated, and the double swing arm 205 will be extended to realize the opening function of the opening and closing component 2. Conversely, the extension of the cylinder arm 302b will cause the swing arm 205 to merge and realize the closing function, thereby realizing the opening and closing of the opening and closing component 2. After opening, the opening and closing plate 206 can bypass the obstacle and be reset.

[0037] In summary, the double-arm opening and closing driving connecting rod mechanism for batch stacking and packaging of paper bags of the utility model can realize effective opening and closing action to bypass obstacles during the packaging process, has good spatial adaptability, and can complete the transportation of paper bags in a limited space. In addition, through the reasonable design of the connecting rod mechanism, the transmission structure can be simplified, and the stability and reliability of the equipment can be improved, thereby reducing the failure rate and improving the user experience; in addition, the paper bags are transported by conveyor belt plus lifting instead of traditional mechanical claws, which effectively solves the problems of unstable gripping and uneven stacking of paper bags caused by mechanical claws, thereby ensuring the appearance and packaging quality of the final product.

[0038] The above description is only a description of the preferred embodiment of the utility model, and is not any limitation on the scope of the utility model. Any changes and modifications made by ordinary technicians in the field of the utility model based on the above disclosure shall fall within the scope of protection of the claims.
