Description

Technical Field

[0001] The utility model relates to the technical field of packaging machinery, in particular to a device for packaging old clothes into small packages. Background Art

[0002] Old clothes are clothes that are no longer used and are a kind of renewable resources. After the old clothes are recycled, they are first classified according to the completeness, material, and type of clothes to achieve the purpose of resource recycling such as reuse and recycling. Old clothes with different treatment methods need to be packed into small packages for easy transportation and storage. Among them, compressing old clothes into blocks and then tying them into packages is the main means of packaging old clothes at present, which mainly relies on existing small vertical balers. The baler is equipped with a box for baling on the frame. The oil cylinder drives the pressure plate to press down, and the clothes are compressed into blocks. After the blocks are formed, the side door of the box is opened, and the wire threading grooves reserved on the pressure plate and the bottom plate of the box are used to thread the binding belt to bundle them into packages.

[0003] However, in actual operations, it is found that old clothes are different from other materials such as waste cardboard boxes and waste plastics. They are soft in texture and not easy to shape. After being compressed into blocks, they are easy to become loose, resulting in frequent secondary packaging processing, increasing the packaging workload and affecting the progress of transportation or storage. Although there is a means of increasing the binding density to avoid looseness, the increase in the binding amount will significantly extend the packaging interval between two batches of old clothes and reduce the packaging efficiency. Therefore, in the packaging of old clothes, there is a general tendency to package them in a way that they are wrapped in plastic bags and then bundled, but the existing small vertical balers cannot achieve this function. For this reason, it is necessary to improve the small vertical baler to improve the above situation. Utility Model Content

DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0023] like Figures 1 to 7As shown together, the device for packing old clothes into small packages includes a frame 1. Conventionally, the frame 1 includes a base 11, on which four columns 12 arranged in a rectangular shape are fixedly provided, and the top ends of the columns 12 are commonly fixedly connected to a top seat 13. A bottom plate 2 is fixedly provided at the bottom of the frame 1, and of course, the bottom plate 2 is fixedly provided on the base 11; a threading groove 21 with a top opening is provided on the bottom plate 2. The top surface of the bottom plate 2 serves as a bearing surface for the compression and packaging process, and the threading groove 21 is used to facilitate the passing of the binding belt 92 to bind the clothing block 9 after packaging. The threading groove 21 can be set according to the requirements of the threading direction. Since the present embodiment requires binding in both directions, the threading groove 21 is arranged in a grid shape with a horizontal and vertical cross arrangement.

[0024] A compression guide cylinder 3 is fixedly provided on the frame 1 just above the bottom plate 2, and the compression guide cylinder 3 is fixedly connected to the four uprights 12. The compression guide cylinder 3 is used to guide the compression direction and to serve as a retaining structure for the old clothes in the initial stage of compression. Since the packaging compression is mainly to compress into a shape similar to a rectangular parallelepiped, the cross section of the compression guide cylinder 3 in this embodiment is set to be rectangular.

[0025] The compression guide cylinder 3 and the bottom plate 2 form a packing space 4, and the finally compressed clothing block 9 is located in the packing space 4. The frame 1 is provided with a side baffle 5 for enclosing the packing space 4 on the side of the packing space 4. The openable side baffle 5 encloses the packing space 4, which can be convenient for wrapping and tying after compression. Conventionally, the side baffle 5 is hinged at one end, and a door locking mechanism is provided between the other end and the frame 1. The door locking mechanism can be easily obtained according to the known technology in the art, and will not be described in detail here.

[0026] Based on the rectangular cross section of the compression guide cylinder 3, four side baffles 5 are provided in this embodiment, and the four side baffles 5 correspond to the four side walls of the compression guide cylinder 3. Preferably, the inner wall of the side baffle 5 is coplanar with the inner wall of the corresponding part of the compression guide cylinder 3, so that after the side baffle 5 encloses the packaging space 4, it can form a continuous compression channel with the compression guide cylinder 3.

[0027] A vertically movable pressing plate 6 is mounted on the frame 1, and the pressing plate 6 is used to press downward into the packing space 4. An air extraction structure 7 is provided at the bottom of the pressing plate 6, and a pressing drive 61 is provided between the pressing plate 6 and the frame 1. Conventionally, the pressing drive 61 includes a pressing drive cylinder.

[0028] In this embodiment, the air extraction structure 7 is added to the pressing plate 6. On the one hand, it can prevent the old clothes from transferring too much pressure of the pressing plate 6 to the side baffle 5 during the pressing process, thereby preventing the old clothes from pulling the plastic bag 91 when being pressed down. On the other hand, it can cooperate with the pressure to make the old clothes shrink quickly, thereby improving the efficiency of a single compression. Preferably, the side baffle 5 is provided with a bag pressing portion 51 extending to the outer side wall of the compression guide cylinder 3, so that the bag pressing portion 51 and the outer side wall of the compression guide cylinder 3 press and fix the upper edge of the plastic bag 91, further preventing the plastic bag 91 from being pulled inward with the old clothes during the compression process.

[0029] The exhaust structure 7 described in this embodiment includes an exhaust port 71 arranged at the bottom surface of the pressing plate 6, and a blocking net 72 is fixedly provided at the exhaust port 71, so that the blocking net 72 can ensure the exhaust and prevent old clothes from blocking the exhaust port 71; the exhaust port 71 pipeline is connected to a vacuum pump, and of course, an exhaust control valve is also provided between the exhaust port 71 and the vacuum pump. The exhaust control valve and the vacuum pump are well-known and commonly used technologies, which will not be repeated here and are not shown in the figure.

[0030] When using, Figure 1 , Figure 2 and Figure 3 As shown, the pressing plate 6 is initially lifted by the pressing driver 61 to a position higher than the compression guide cylinder 3, and a feed port is formed between the pressing plate 6 and the upper end of the compression guide cylinder 3, through which old clothes can be put in. If necessary, an additional notch can be opened at the upper end of the compression guide cylinder 3 to increase the area of ​​the feed port. The plastic bag 91 is put on the lower end of the compression guide cylinder 3, and it is preferable that the bottom of the plastic bag 91 can be spread flat on the bottom plate 2. The four side baffles 5 are closed, and the four side baffles 5 enclose the packaging space 4 to form a rigid support for the side of the plastic bag 91, and after closing, the bag pressing part 51 presses the upper edge of the plastic bag 91.

[0031] The process of adding old clothes makes sure that the old clothes fill the packing space 4 as evenly as possible, and the filling height is appropriately higher than the packing space 4 according to the compression ratio of the old clothes. After the addition is completed, the downward pressing driver 61 drives the pressing plate 6 to press down, and when the pressing plate 6 is pressed down to the vicinity of the old clothes, the exhaust control valve is opened, and the exhaust structure 7 starts to exhaust air under negative pressure. In the process of continuing to press down, under the influence of active exhaust, the old clothes do not produce obvious pulling on the plastic bag 91, and the bag pressing part 51 presses the upper edge of the plastic bag 91, so that the plastic bag 91 can basically maintain a posture close to the side baffle 5, until the pressing plate 6 is pressed down to the point where it can no longer be pressed down, and the pressing plate 6 enters the packing space 4, as shown in FIG. Figure 5 As shown, the compressed clothing block 9 is located between the pressing plate 6 and the bottom plate 2 and is substantially in the shape of a rectangular parallelepiped.

[0032] like Figure 4 and Figure 6 As shown, the side baffle door 5 is opened, and the binding belt 92 is inserted into the threading groove 21. Preferably, while maintaining the air extraction, the pressing drive 61 is controlled to lift the pressing plate 6 into the lower end of the compression guide cylinder 3, as shown in FIG. Figure 7 As shown, during this process, the compressed clothing block 9 is kept against the bottom plate 2 due to its own gravity, and the suction force of the air extraction structure 7 drives the upper end of the plastic bag 91 to be recessed into the space between the pressing plate 6 and the clothing block 9, so that the upper end of the plastic bag 91 can be quickly wrapped on the clothing block 9 by the human. Then, the air extraction is stopped, and the pressing plate 6 is lifted to the initial position. After the human has finished tying the clothing block 9, it is output from one of the opened side doors 5.

[0033] An empty plastic bag 91 is put on the lower end of the compression guide cylinder 3 again, the side baffle door 5 is closed, and the next batch of old clothes is put in, and the above packaging process is repeated.

[0034] Through the above structural principle, this embodiment realizes the wrapping and bundling of the plastic bag 91 of the old clothes into a package, which is conducive to preventing the packaging from being loose. Based on the wrapping effect of the plastic bag 91, the packaging process does not need to increase the bundling, and the compression process cooperates with negative pressure extraction to increase the compression speed. The binding process uses negative pressure extraction to assist the plastic bag 91 to wrap, and the overall packaging efficiency is high.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
