Description

Technical Field

[0001] The utility model relates to the technical field of plastic bag manufacturing, in particular to a manipulator for folding plastic bags. Background Art

[0002] In the field of plastic bag production and manufacturing, the stacked plastic bags after being manufactured need to be perfectly folded before they can be packaged and sold as a sales unit. When folding the plastic bags, a manipulator for clamping the plastic bags is required to transport the plastic bags between multiple folding stations. At the same time, when folding the plastic bags, the non-folded part of the plastic bags needs to be pressed by a pressing plate mechanism to ensure the folding problem. Commonly, the whole pressing plate mechanism is installed on the frame.

[0003] During folding, since the pressing plates on both sides for folding the plastic bags need to completely fold the plastic bags above the pressing plates, the driving component of the pressing plate mechanism cannot be directly arranged above the pressing plate, otherwise it will collide with the lateral folding.

[0004] At the same time, after folding is completed, the pressing plate mechanism also needs to be withdrawn laterally to facilitate the subsequent transfer operation of the plastic bags.

[0005] In the prior art, the pressing plate is separately installed on the frame, and the pressing plate extends laterally from the telescopic end of the cylinder, so as to avoid collision during pressing and folding. At the same time, a second group of cylinders for laterally withdrawing the whole pressing plate cylinder needs to be additionally arranged to realize the lateral withdrawal of the pressing plate. The structure is relatively complex, and at the same time, it is necessary to consider avoiding collision with the reciprocating manipulator on the frame, and the stroke of the telescopic mechanism needs to be extended, increasing the equipment cost and reducing the stability of the equipment. Summary of the Utility Model

[0006] The technical problem to be solved by the utility model is, in view of the above-mentioned technical deficiencies, to provide a manipulator for folding plastic bags. By integrating the pressing plate mechanism onto the manipulator, a telescopic mechanism with a telescopic end extending downward is arranged on the manipulator, and a pressing plate extending to one side is arranged at the telescopic end of the telescopic mechanism, so as to realize the pressing of the plastic bags during folding of the plastic bags and avoid collision with the folding mechanism at the same time. At the same time, by integrating the pressing plate mechanism onto the manipulator and utilizing the reciprocating movement of the manipulator itself, the lateral withdrawal of the pressing plate after folding is realized, reducing the setting cost of additionally arranging a pressing plate withdrawal cylinder. At the same time, by integrating the pressing plate mechanism onto the manipulator, it is no longer necessary to extend the pressing plate mechanism too long to realize the pressing of the plastic bags, reducing the stroke length of the telescopic components in the pressing plate mechanism and reducing the equipment manufacturing cost.

[0007] To solve the above technical problems, the technical solution adopted by the present utility model is as follows: It includes a main frame; the main frame is slidably arranged on the machine frame; a driving mechanism for driving the movement of the main frame is also arranged on the machine frame; a clamping mechanism for clamping a plastic bag is installed on the main frame, and a pressing plate mechanism for pressing the plastic bag is also installed on the main frame; the pressing plate mechanism includes a telescopic mechanism with its telescopic end facing downward; and a pressing plate installed at the telescopic end of the telescopic mechanism, and the pressing plate extends towards one side along the movement direction of the main frame.

[0008] To further optimize this technical solution, a guide rail perpendicular to the movement direction of the main frame is arranged on the main frame; both the clamping mechanism and the pressing plate mechanism are detachably installed on the guide rail through guide rail sliders.

[0009] To further optimize this technical solution, a plurality of clamping mechanisms and pressing plate mechanisms are arranged on the guide rail; the pressing plate mechanism is arranged between the clamping mechanisms.

[0010] To further optimize this technical solution, the telescopic mechanism is a cylinder; a base plate extends towards one side of the guide rail slider for installing the pressing plate mechanism; the cylinder is installed on the base plate; the telescopic end of the cylinder faces downward and is installed with a pressing plate.

[0011] To further optimize this technical solution, a guide sleeve is also arranged on the base plate; a guide post is arranged on the pressing plate; the guide post is slidably arranged in the guide sleeve.

[0012] Compared with the prior art, the present utility model has the following advantages: By integrating the pressing plate mechanism onto the manipulator, through setting a telescopic mechanism with its telescopic end facing downward on the manipulator and arranging a pressing plate extending towards one side at the telescopic end of the telescopic mechanism, the pressing of the plastic bag is achieved when the plastic bag is folded, and at the same time, collision with the folding mechanism is avoided; meanwhile, by integrating the pressing plate mechanism onto the manipulator and utilizing the reciprocating movement of the manipulator itself, the lateral extraction of the pressing plate after folding is realized, reducing the setting cost of additionally arranging a pressing plate extraction cylinder; at the same time, by integrating the pressing plate mechanism onto the manipulator, it is no longer necessary to extend the pressing plate mechanism too long to achieve the pressing of the plastic bag, reducing the stroke length of the telescopic components in the pressing plate mechanism and reducing the manufacturing cost of the equipment.

[0017] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in combination with the specific implementation manners and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0018] Detailed implementation manner: As shown in combination with Figures 1-3 the figure, it includes a frame 2; a manipulator capable of reciprocating motion is provided on the frame 2, the manipulator is driven by a driving mechanism 3, the driving mechanism 3 includes a motor provided on the frame 2, and a belt that can rotate forward and backward driven by the motor, the main frame 1 that makes up the manipulator is fixedly connected to the belt, realizing the reciprocating motion of the manipulator. The clamping mechanism 4 is a mechanism that controls and realizes the clamping of plastic bags through a cylinder 9 or an oil cylinder or other clamping components. The plastic bag folding manipulator includes a main frame 1; the main frame 1 is slidably arranged on the frame 2; a driving mechanism 3 for driving the main frame 1 to move is further provided on the frame 2; a clamping mechanism 4 for clamping plastic bags is installed on the main frame 1, and a pressing plate mechanism 5 for pressing plastic bags is further installed on the main frame 1; the pressing plate mechanism 5 includes a telescopic mechanism with a telescopic end arranged downward; and a pressing plate 6 installed at the telescopic end of the telescopic mechanism, the pressing plate 6 extends to one side along the moving direction of the main frame 1; a guide rail 7 perpendicular to the moving direction of the main frame 1 is provided on the main frame 1; both the clamping mechanism 4 and the pressing plate mechanism 5 are detachably installed on the guide rail 7 through guide rail sliders 8; the guide rail slider 8 is a prior art, and a locking component is provided thereon to realize fixation and movement at any position on the guide rail 7; a plurality of clamping mechanisms 4 and pressing plate mechanisms 5 are provided on the guide rail 7; the pressing plate mechanism 5 is arranged between the clamping mechanisms 4; the telescopic mechanism is a cylinder 9; the guide rail slider 8 for installing the pressing plate mechanism 5 extends to one side and is provided with a substrate 10; the cylinder 9 is installed on the substrate 10; the telescopic end of the cylinder 9 is arranged downward and is installed with a pressing plate 6; a guide sleeve 11 is further provided on the substrate 10; a guide post 12 is provided on the pressing plate 6; the guide post 12 is slidably arranged in the guide sleeve 11.

[0019] In combination with Figures 1-3As shown, during use, the clamping mechanism 4 installed on the main frame 1 of the manipulator drags the plastic bag to the corresponding station in the front process of the plastic bag. Driven by the driving mechanism 3, the main frame 1 reciprocates to complete the operation, which is the prior art content. The additionally provided pressing plate mechanism 5 will not affect the realization of the original functions of the manipulator.

[0020] Combined with Figures 1-3 As shown, at the same time, when the plastic bag is dragged to the folding station, the pressing plate mechanism 5 installed on the main frame 1 is pushed by the cylinder 9 therein, and the pressing plate 6 is pressed down to the upper side of the non-folded part of the plastic bag, facilitating the folding of the plastic bag by the equipment. The pressing plate 6 extends to one side along the moving direction of the main frame 1, avoiding the collision between the pressing plate 6 and the plastic bag folding mechanism.

[0021] Combined with Figures 1-3 As shown, at the same time, the pressing plate 6 provided on the manipulator does not need to extend downward too long. The cylinder 9 used here can be a cylinder 9 with a shorter stroke, reducing the manufacturing cost of the equipment. Through the cooperation of the guide post 12 and the guide sleeve 11, the stable use of the pressing plate 6 during the pressing down and lifting processes is ensured. When the folding of the plastic bag is completed, at this time, it is necessary to draw out the pressing plate 6 along the moving direction of the main frame 1. Through the original driving mechanism 3 of the manipulator, the lateral drawing out of the pressing plate 6 can be realized, without additionally setting components for driving the drawing out of the pressing plate 6, enhancing the versatility of the mechanisms in the equipment and further simplifying the manufacturing cost of the equipment.

[0022] Combined with Figures 1-3 As shown, at the same time, the clamping mechanism 4 and the pressing plate mechanism 5 are installed on the guide rail 7 through guide rail 7 sliders. After unlocking the guide rail 7 sliders, the installation positions and layouts of the clamping mechanism 4 and the pressing plate mechanism 5 on the guide rail 7 can be freely adjusted. Since usually the folding station is located in the middle of the equipment and the pressing plate mechanism 5 is usually located in the middle of the clamping mechanism 4, it can also be freely adjusted according to different plastic bag manufacturing situations.

The control circuit of the controller can be realized by simple programming by those skilled in the art, which belongs to the common general knowledge in the art.
