Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging machine technology, and in particular to a continuous folding device for packaging machines. Background Technology
[0002] When packaging materials with a large area, the packaging machine needs to perform multiple folds, including multiple folding channels. The folding channels are connected to folding push plates. During the folding process, a conveyor belt is often needed for transfer, which takes up a lot of space and can easily lead to loosening after folding. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a continuous folding device for packaging machines.
[0004] This utility model is achieved through the following technical solution: a continuous folding device for a packaging machine, comprising multiple sets of folding channels arranged sequentially, with folding push plates disposed between adjacent sets of folding channels. The multiple sets of folding channels include a first folding channel, a downward connecting plate disposed at the lower end of the first folding channel, an upward cylinder mounted on the connecting plate, the piston rod of the first cylinder connected to the upward folding push plate, the first folding channel opening at the middle position and connecting to a second folding channel, the second folding channel connecting to a second folding push plate, the second folding channel opening at the middle position and connecting to a third folding channel, the third folding channel connecting to a third folding push plate, the third folding channel opening at the middle position and connecting to a fourth folding channel, and the fourth folding channel connecting to a fourth folding push plate.
[0005] Furthermore, an auxiliary positioning device is provided on one side of the folding channel. The auxiliary positioning device includes a second cylinder, and a top head is installed at the end of the piston rod of the second cylinder. The top head can be inserted into the first folding channel.
[0006] Furthermore, the folded channel is equipped with boundary detection devices at three locations.
[0007] Furthermore, openings are machined at the three ends of the folded channel to form a defective channel, which is connected to a defective material box.
[0008] Furthermore, the defective channel is also connected to a pneumatic gripper.
[0009] Furthermore, the first folding channel, the second folding channel, the third folding channel, and the fourth folding channel are all formed by plates.
[0010] The beneficial effects of this utility model are as follows:
[0011] 1. Folding channels 1, 2, 3, and 4 are directly connected, occupying little space, with a compact structure, and can prevent materials from becoming loose during the conveying process;
[0012] 2. When the material is in the first folding channel, the number of folds is less and the thickness is thinner. The top head can be inserted into the first folding channel to assist in clamping the material, so that the material is positioned in the first folding channel. Attached Figure Description

[0015] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0017] Example 1
[0018] like Figure 1As shown, a continuous folding device for a packaging machine is used to fold triangular bandages. It includes multiple sets of conveyor channels arranged sequentially, with folding push plates installed between adjacent sets of conveyor channels. Specifically, a downward connecting plate 10 is installed at the lower end of folding channel 1, and an upward-moving cylinder 11 is installed on the connecting plate 10. The piston rod of cylinder 11 connects to the upward-moving folding push plate 1, thus folding the triangular bandage once. Because the number of folds is small and the thickness is thin, an auxiliary positioning device 7 is installed on the side of folding channel 1. The auxiliary positioning device 7 includes a cylinder 2, with a push head installed at the end of the piston rod of cylinder 2. The push head can be inserted into folding channel 1 to assist in clamping the triangular bandage, positioning it within folding channel 1. Holes are machined on the side wall of folding channel 1 to mate with the push head, and an opening is machined on the folding push plate 1 to mate with the push head. An opening is located in the middle of folding channel 1. The first channel is connected to folding channel 2 (3), which is connected to folding push plate 2 (2). Folding channel 2 (3) has an opening in the middle and is connected to folding channel 3 (5). Folding channel 3 (5) is connected to folding push plate 3 (4). A boundary detection device 6, which is a photoelectric sensor, is installed at folding channel 3 (5). The boundary detection device 6 detects the upper edge of the triangular bandage. When the photoelectric sensor is triggered, it is determined that the triangular bandage is not folded properly. An opening is processed at the end of folding channel 3 (5) to form a defective channel 8. Defective channel 8 is connected to defective material box 12. Defective channel 8 is also connected to a pneumatic gripper 13. The pneumatic gripper 13 is driven by a cylinder to the defective channel 8 and then actuates to pick up the defective triangular bandage and put it into the defective material box 12. Folding channel 3 (5) has an opening in the middle and is connected to folding channel 4 (9). Folding channel 4 (9) is connected to folding push plate 4 (14). The folded triangular bandage is pushed out through folding channel 4 (9).
[0019] The lengths of folding channels 1, 2, 3, 3, and 4 are successively shortened. At folding channels 2, 3, 3, and 4, the triangular bandages are squeezed and fixed by their own elasticity due to the numerous folds. Folding channels 1, 2, 3, 3, and 4 are all made of stainless steel plates with high surface smoothness and high wear resistance. Folding push plates 2, 3, and 4 are all driven by cylinders, resulting in fast operation.
[0020] The feed end of the folding channel 1 can be connected to the clamping conveyor belt 15, which feeds the material into the folding channel 1. The material is pushed upward into the continuous folding device of the packaging machine within the folding channel 1 and folded once. There is a transverse support plate 16 at the end of the clamping conveyor belt 15, which improves the load-bearing capacity of the clamping conveyor belt 15.
[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
