[0023] The following is a more detailed description of the automatic liquid yellowing agent addition device for polyester recycled materials of the present invention, with reference to a schematic diagram. This diagram illustrates a preferred embodiment of the present invention. It should be understood that those skilled in the art may modify the present invention as described herein while still achieving the beneficial effects of the present invention. Therefore, the following description should be understood as a general guide for those skilled in the art and not as a limitation of the present invention.

[0024] The following paragraphs describe the present invention in more detail by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the drawings are greatly simplified and not to exact scale, and are intended solely to facilitate and clearly illustrate the embodiments of the present invention.

[0025] like Figures 1 to 3 As shown, an embodiment of the present invention provides an automatic adding device for liquid yellowing remover for polyester recycled materials, comprising a vehicle body 1 , a guide rail 2 , a material barrel 3 and a screw pump 4 .

[0026] Specifically, a docking cavity 5 matching the material barrel 3 is provided on the vehicle body 1 , and a feeding channel 6 communicating with the material barrel 3 is provided on the inner wall of the docking cavity 5 .

[0027] The guide rail 2 is fixedly arranged on the vehicle body 1 , and the guide rail 2 is located outside the docking cavity 5 .

[0028] The material barrel 3 is movably arranged on the guide rail 2 . The material barrel 3 is docked with the inner wall of the docking cavity 5 by sliding along the guide rail 2 and is communicated with the feeding channel 6 .

[0029] The screw pump 4 is fixedly mounted on the vehicle body 1 , and the screw pump 4 is located below the guide rail 2 , and the feed port of the screw pump 4 is fixedly connected to the feeding channel 6 .

[0030] In this embodiment, when raw materials need to be added, the corresponding barrel 3 is placed on the guide rail 2 and pushed to dock with the docking cavity 5. At this time, the barrel 3 and the feeding channel 6 can be quickly connected. The raw materials are then added to the barrel 3, and finally the screw pump 4 sucks the raw materials out of the feeding channel 6 and feeds them into the device to be added through the pipeline, completing the raw material addition.

[0031] In one embodiment, a transparent window 7 is provided on the side wall of the barrel 3, and a scale mark 8 is provided on the transparent window 7. The provision of the transparent window 7 and the scale mark 8 allows the remaining amount of raw materials in the barrel 3 to be visually observed, facilitating timely addition of raw materials to the barrel 3.

[0032] It should be noted that the quick removal and installation of the barrel 3 during cleaning and replacement greatly reduces the operator's workload and facilitates operation. Furthermore, in order to facilitate the movement of the automatic addition device for the liquid yellowing agent for polyester recycled material to the location of the equipment to be added, a push-pull handle 9 is provided on the vehicle body 1.

[0033] Furthermore, to achieve automatic addition of the anti-yellowing agent, a screw pump can be used for timed delivery. The screw pump delivers a constant amount of material per unit time, and the automatic quantitative addition of the anti-yellowing agent can be controlled by controlling the screw pump's delivery time. Timing control of the screw pump is a common technique used in this technology and will not be detailed here.

[0034] Furthermore, a docking plug 10 is fixedly provided at the bottom of the barrel 3, and a docking sleeve 11 is provided at the end of the feeding channel 6. The docking plug 10 and the docking sleeve 11 are detachably connected.

[0035] Specifically, during the process of moving and docking barrel 3 with docking chamber 5, docking cannula 10 is inserted into docking sleeve 11, enabling rapid docking between barrel 3 and feed channel 6. Simultaneously, the other end of feed channel 6 is connected via a pipe to the feed port of screw pump 4. When screw pump 4 is operating, it delivers the material in barrel 3 to the device to be added.

[0036] In a specific embodiment, a sealing gasket 12 is provided between the docking spigot 10 and the docking sleeve 11. In order to improve the sealing between the docking spigot 10 and the docking sleeve 11 and reduce the risk of raw material leakage, a sealing gasket 12 is provided between the docking spigot 10 and the docking sleeve 11.

[0037] Furthermore, an adsorption magnetic sheet 13 is provided on the inner wall of the docking cavity 5 , and the adsorption magnetic sheet 13 is connected to the surface of the barrel 3 by magnetic adsorption.

[0038] Specifically, after the docking tube 10 and the docking sleeve 11 are docked, the outer wall of the barrel 3 is magnetically adsorbed on the inner wall of the docking cavity 5, so that the docking tube 10 and the docking sleeve 11 maintain a stable connection relationship, thereby ensuring the smooth progress of the raw material addition work.

[0039] In one embodiment, the adsorption magnetic sheet 13 is embedded in the inner wall of the docking cavity 5, and the outer surface of the adsorption magnetic sheet 13 is flush with the inner wall of the docking cavity 5. This design allows the outer wall of the barrel 3 to fit more closely with the inner wall of the docking cavity 5 and the adsorption magnetic sheet 13, thereby firmly fixing the barrel 3.

[0040] Furthermore, a positioning bracket 14 is provided at the bottom of the material barrel 3 , and when the material barrel 3 slides along the guide rail 2 , the positioning bracket 14 fits and slides in contact with the side of the guide rail 2 .

[0041] Specifically, two symmetrical positioning brackets 14 are provided, and each positioning bracket 14 is configured in a cylindrical shape. When the barrel 3 slides along the guide rail 2, the positioning bracket 14 acts as a limit, so that the barrel 3 can accurately achieve docking between the docking spigot 10 and the docking sleeve 11 during movement, thereby achieving a quick connection between the barrel 3 and the feeding channel 6.

[0042] Among them, the positioning bracket 14 is configured to be cylindrical, which can reduce the friction resistance and wear between the positioning bracket 14 and the guide rail 2, and plays a certain protective role.

[0043] Compared with the prior art, the present invention has at least the following beneficial effects:

[0044] The utility model can realize quick docking with the docking chamber by moving the material barrel along the guide rail, thereby realizing communication between the material barrel and the screw pump. At this time, the material in the material barrel can be quickly added to the designated material bin through the screw pump, realizing rapid filling of the material, and has the characteristics of simple structure and convenient operation.

[0045] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
