Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic bag production, in particular to a movable receiving device for plastic bags. Background Art
[0002] When large plastic bags are produced and packaged, multiple large plastic bags need to be stacked and then folded as a whole to form portions for individual sale.
[0003] During the production of plastic bags, they are placed on the platform and then wait for folding. Because the plastic bags are too large, when they are stacked on the suspended platform on one side, the ends of the suspended plastic bags are prone to drift during the fall, making the stacking not neat, and the rapid stacking process makes the plastic bags on the lower side not completely fall, further affected by the plastic bags on the upper side, further affecting the normal stacking of the plastic bags; and when the plastic bags are completely laid flat on the platform for stacking, although the stacking effect is guaranteed, it is still necessary to remove the entire plastic bag. The flat plastic bags are not conducive to the removal operation of the robot. Even if they can be removed, it is necessary to set up a stacking station and a subsequent folding station at the same time, which increases the production line, is costly, and is not conducive to promotion. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a movable receiving device for plastic bags in view of the above-mentioned technical deficiencies. The movable receiving area is adopted to achieve flat receiving when receiving and stacking plastic bags, thereby ensuring the stacking quality of the plastic bags. At the same time, after the stacking is completed, the receiving area is reduced so that part of the plastic bags hang down, so that the robot arm can clamp the plastic bags.
[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: it includes a frame, and the frame is provided with a receiving belt with two ends fixed to the frame; the receiving belt is arranged along the conveying direction of the plastic bags; the middle part of the receiving belt is arranged around the first roller; the frame is also provided with a driving mechanism for driving the first roller to reciprocate; the receiving belt forms a receiving area from the position where it is fixedly connected to the frame on one side along the plastic bag input direction to the position where it is around the first roller.
[0006] To further optimize the technical solution, when receiving a plastic bag, the receiving area is equal to or longer than the plastic bag, so that the plastic bag can fall completely on the receiving area; after receiving the plastic bag, the driving mechanism drives the first roller to move in the direction of shrinking the receiving area, so that one side of the plastic bag naturally hangs down.
[0007] To further optimize the technical solution, roller frames are provided at both ends of the first roller; an output frame is also provided on one side of the roller frame; and a notch for clamping by a robot is provided on one side of the output frame.
[0008] To further optimize this technical solution, the driving mechanism includes slide rails arranged on both sides of the frame. Both ends of the first roller are slidably connected to the slide rails through roller frames, and a motor and a belt are arranged on one side of the frame. The belt is fixedly connected to the roller frame.
[0009] To further optimize this technical solution, the output frame and the receiving area of the receiving belt are in a parallel position on the same plane.
[0010] To further optimize this technical solution, a second roller is also arranged on the roller frame. The non-receiving area part of the receiving belt is wound around the second roller and then fixedly connected to the frame.
[0011] Compared with the prior art, the utility model has the following advantages: 1. By extending the state of the movable receiving area, this structure effectively realizes the receiving of the entire length of a relatively long plastic bag through the front and rear receiving areas with the same height, avoiding the problem that the end of the plastic bag in the air is prone to falling and drifting, resulting in uneven stacking, and in the process of rapid stacking, the plastic bag on the lower side has not completely fallen, and is further affected by the plastic bag on the upper side; 2. At the same time, by reducing the movable receiving area, this structure effectively realizes the clamping of the stacked plastic bags at the stacking station by suspending one side of the stacked plastic bags, avoiding the problem that when the plastic bags are completely laid flat on the platform for stacking, although the stacking effect is guaranteed, the entire plastic bag still needs to be removed, and the laid flat plastic bags are not conducive to the manipulator for removal operations. Even if it can be removed, it is necessary to set up a stacking station and a subsequent folding station at the same time, resulting in an increase in the production line length.

[0016] To make the objectives, technical solutions, and advantages of the present utility model clearer, the present utility model will be further described in detail below in conjunction with specific embodiments 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 descriptions, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.
[0017] Specific embodiments: As shown in Figures 1-3 Figure 5, it includes a frame 1, and a receiving belt 2 with both ends fixed to the frame 1 is provided on the frame 1; the receiving belt 2 is arranged along the conveying direction of the plastic bag; the middle part of the receiving belt 2 is wound around a first roller 3; a driving mechanism 4 for driving the first roller 3 to reciprocate is further provided on the frame 1; a receiving area 5 is formed between the position where the receiving belt 2 is fixedly connected to the frame 1 on one side along the plastic bag input direction and the position where it is wound around the first roller 3.
[0018] When receiving the plastic bag, the receiving area 5 is as long as or longer than the plastic bag, so that the plastic bag can completely fall onto the receiving area 5; after receiving the plastic bag, the driving mechanism 4 drives the first roller 3 to move in the direction of reducing the receiving area 5, so that one side of the plastic bag naturally droops
[0019] Both ends of the first roller 3 are provided with roller frames 6; an output frame 7 is further provided on one side of the roller frame 6; a notch 8 for the manipulator to grip is provided on one side of the output frame 7.
[0020] The driving mechanism 4 includes slide rails 9 arranged on both sides of the frame 1, both ends of the first roller 3 are slidably connected to the slide rails 9 through the roller frames 6, and a motor 10 and a belt 11 arranged on one side of the frame 1, and the belt 11 is fixedly connected to the roller frame 6.
[0021] The output frame 7 and the receiving area 5 of the receiving belt 2 are in parallel positions in the same plane.
[0022] A second roller 12 is further provided on the roller frame 6, and the non-receiving area 5 part of the receiving belt 2 is wound around the second roller 12 and then fixedly connected to the frame 1.
[0023] When receiving the plastic bag, as shown in Figures 1-3 Figure 5, the motor 10 drives the belt 11 to rotate, and then drives the roller frame 6 to drive the first roller 3 to move in the direction of expanding the receiving area 5. Since both ends of the receiving belt 2 are fixed, the receiving area 5 range of the receiving belt 2 is expanded by driving the receiving belt 2 through the first roller 3, so that the plastic bag can almost completely fall onto the receiving area 5;
[0024] When outputting plastic bags, since both ends of the receiving belt 2 are fixed, when the motor 10 drives the belt 11 to rotate, and then drives the roller frame 6 to drive the first roller 3 to move towards the direction of shrinking the receiving area 5, the plastic bags originally in the receiving area 5 will not shrink as a whole because the ends of the receiving belt 2 are fixed. Instead, as the receiving area 5 shrinks, they droop downward at the edge position. At the same time, since an output frame 7 is provided at the edge of the receiving area 5, the middle part of the drooping plastic bags is located at the corresponding position of the notch 8 of the output frame 7, facilitating the subsequent manipulator to clamp and take away all the plastic bags by clamping the plastic bags at the notch 8 position.
[0025] The control mode of the present utility model is automatically controlled by a controller. 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. And the present utility model is mainly used to protect mechanical settings, so the control mode and circuit connection of the present utility model will not be explained in detail.
[0026] It should be understood that the above specific embodiments of the present utility model are only used for exemplary illustration or explanation of the principle of the present utility model, and do not constitute a limitation to the present utility model. Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present utility model shall be included within the protection scope of the present utility model. In addition, the appended claims of the present utility model are intended to cover all changes and modification examples falling within the scope and boundary of the appended claims, or equivalent forms of such scope and boundary.
