DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0032] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0033] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0034] The present invention provides a glue stripping machine, which is applied to the field of battery manufacturing. The glue stripping machine includes a glue stripping device, a winding device, and a waste material suction device. Usually, the glue stripping device and the winding device are used to strip the adhesive tape on the electrode material strip, and the waste material suction device sucks and processes the waste glue at the same time.

[0035] See also Figure 1 and Figure 2 The waste suction device 10 provided by the present invention comprises a negative pressure chamber 100, at least two negative pressure pipes 200 and a waste pipe 400. The waste includes, but is not limited to, waste rubber.

[0036] Among them, at least two negative pressure pipes 200 and a waste pipe 400 are respectively connected to different parts of the negative pressure chamber 100, and at least one negative pressure pipe 200 is used to provide negative pressure for the negative pressure chamber 100.

[0037] In the present embodiment, at least one negative pressure pipe 200 acts on the negative pressure chamber 100 to form a negative pressure state in the negative pressure chamber 100, thereby adsorbing the waste in the waste pipe 400 into the negative pressure chamber 100; not only that, by setting at least two negative pressure pipes 200, when one of the negative pressure pipes 200 is blocked, the other negative pressure pipe 200 can be opened, thereby ensuring that the waste suction work is carried out uninterruptedly and the waste suction efficiency is guaranteed, and the blocked negative pressure pipe 200 can be cleaned, so that there is no need to set a cleaning device to clean the negative pressure pipe 200, or compared with the situation where this embodiment is not adopted, the number of cleaning devices can be reduced, or a cleaning device with a low cleaning effect can be used, thereby reducing production costs and improving production efficiency.

[0038] For further information, please refer to Figures 1 to 6 , at least two negative pressure pipes 200 include a first pipe 210 and a second pipe 220, and the waste suction device 10 also includes a negative pressure generator 500, a pusher 800, a conveyor 600 and a cutter 700, wherein the negative pressure generator 500 is connected to the first pipe 210 and the second pipe 220, the pusher 800 is connected to the bottom of the negative pressure chamber 100, the conveyor 600 is connected to the waste pipe 400, and the cutter 700 is arranged in the waste pipe 400.

[0039] The negative pressure generator 500 is provided with a main pipeline 510 , and the first pipeline 210 and the second pipeline 220 are both connected to the main pipeline 510 .

[0040] It is understandable that the number of the first pipeline 210 and the second pipeline 220 can include multiple ones, which can be adjusted according to actual needs. No specific limitation is made on the number setting of the first pipeline 210 and the second pipeline 220. For the convenience of description, this article uses an embodiment in which the number of the first pipeline 210 and the second pipeline 220 is one for description.

[0041] Optionally, the negative pressure generator 500 includes, but is not limited to, an exhaust fan, an air compressor, and the like.

[0042] In this embodiment, the main pipeline 510 forms a three-way pipe structure with the first pipeline 210 and the second pipeline 220. The first pipeline 210 is provided with a first valve (not shown), and the second pipeline 220 is provided with a second valve (not shown). When the negative pressure generator 500 is started, the first valve or the second valve is opened, or the first valve and the second valve are opened at the same time, so that the first pipeline 210 or the second pipeline 220 is connected, or the first pipeline 210 and the second pipeline 220 are connected at the same time, thereby providing a vacuum or negative pressure environment for the negative pressure chamber 100 through the first pipeline 210 and the second pipeline 220.

[0043] In this embodiment, the first valve can be opened and the second valve can be closed to make the first pipe 210 conductive and provide negative pressure for the negative pressure chamber 100. In this case, the air flow flows through the waste pipe 400, the negative pressure chamber 100, the first pipe 210 and the main pipe 510 in sequence, and the waste in the waste pipe 400 is adsorbed into the negative pressure chamber 100.

[0044] In actual applications, after the first pipe 210 has been open for a long time, the first pipe 210 or the negative pressure chamber 100 may be blocked by dust or debris. In this case, the second valve can be opened to make the second pipe 220 open, and the first valve can be closed. In this case, the airflow flows through the waste pipe 400, the negative pressure chamber 100, the second pipe 220 and the main pipe 510 in sequence, and continues to adsorb the waste into the negative pressure chamber 100, so as to continuously adsorb the waste, ensure uninterrupted action, and improve production efficiency; at the same time, the dust or debris blocking the first pipe 210 or the negative pressure chamber 100 can be separated from the first pipe 210 or the negative pressure chamber 100 under the adsorption action of the second pipe 220, thereby playing a role in cleaning the first pipe 210 and the negative pressure chamber 100, so that there is no need to set up a separate cleaning device, thereby reducing production costs.

[0045] It is understandable that in other usage scenarios, the first valve and the second valve may also be opened at the same time, so that the first pipeline 210 and the second pipeline 220 are connected at the same time.

[0046] Furthermore, the waste pipe 400 and the second pipe 220 are respectively connected to the opposite ends of the negative pressure chamber 100 , and the first pipe 210 is connected to the negative pressure chamber 100 and is located between the second pipe 220 and the waste pipe 400 .

[0047] In this embodiment, the waste pipe 400 can be connected to the top of the negative pressure chamber 100, the second pipe 220 can be connected to the top of the negative pressure chamber 100, and the first pipe 210 can be connected to the middle of the negative pressure chamber 100, so that the first pipe 210 and the second pipe 220 can be adsorbed from different parts and directions of the negative pressure chamber 100, so that the dust or debris blocked in the first pipe 210 or the negative pressure chamber 100 can be cleaned through the second pipe 220 when the second pipe 220 is turned on; not only that, the waste pipe 400 is connected to the top of the negative pressure chamber 100, so that the waste can be adsorbed into the negative pressure chamber 100 and fall into the bottom of the negative pressure chamber 100 under the action of gravity, and fall into the pusher 800 from the bottom of the negative pressure chamber 100, thereby pushing the waste suction device 10 out through the pusher 800.

[0048] Furthermore, a buffer chamber 110 is provided in the negative pressure chamber 100 , the first pipe 210 is connected to the buffer chamber 110 , and a filter element 300 is provided between the negative pressure chamber 100 and the buffer zone, and the filter element 300 is used to prevent waste from entering the buffer chamber 110 .

[0049] In this embodiment, the filter element 300 is provided to prevent waste from being directly sucked into the first pipe 210 due to the adsorption effect of the first pipe 210. However, the long-term adsorption effect of the first pipe 210 may cause the filter element 300 to be blocked by dust or debris. In this case, the first pipe 210 is disconnected and the second pipe 220 is connected. While the second pipe 220 adsorbs the waste, it can also generate a downward pulling force on the dust or debris blocked in the filter element 300, thereby having a cleaning effect on the filter element 300.

[0050] Optionally, the filter element 300 may be a filter net.

[0051] Furthermore, the conveyor 600 includes a shaping roller 610 and a plurality of guide rollers 620 , wherein the plurality of guide rollers 620 are used to convey the waste material, the shaping roller 610 is provided with a groove, and the shaping roller 610 and at least one guide roller 620 jointly roll the waste material.

[0052] In this embodiment, the waste is conveyed by the conveyor 600 before entering the waste pipe 400. The waste is guided and conveyed by a plurality of guide rollers 620, and some of the guide rollers 620 are rotatable to improve the conveying capacity of the waste.

[0053] In the present embodiment, when the waste is in the form of long strips, it is flexible and prone to curling and agglomeration. Especially when the waste is waste rubber, it is sticky and more likely to curl and agglomerate, and there is a risk of adhering to the pipeline. A guide roller 620 is provided before entering the waste pipeline 400, and a shaping roller 610 is provided to cooperate with the guide roller 620. A groove is provided on the surface of the shaping roller 610 to roll and shape the waste so that the waste is wrinkled, thereby reducing the probability of curling of the waste. This effectively improves the waste transportation efficiency and further reduces the probability of the waste agglomerating and causing pipeline blockage due to its own winding and curling.

[0054] Furthermore, the cutter 700 is disposed in the waste pipe 400 and is used to cut the waste. The cutter 700 crushes the waste in the waste suction pipe 400 to prevent the waste sucked into the negative pressure chamber 100 from being too long, which makes the waste easily curled and adhered, thereby causing a blockage problem.

[0055] In this embodiment, the cutter 700 includes a first cutting member 710, a second cutting member 720, a bracket 730 and a rotating drum 740. The first cutting member 710, the second cutting member 720 and the rotating drum 740 are all arranged on the bracket 730. The rotating drum 740 rotates with the bracket 730. The first cutting member 710 includes a first cutting ring 711 and a first cutting strip 712 arranged in the first cutting ring 711. The first cutting ring 711 is fixedly connected to the bracket 730. The second cutting member 720 includes a second cutting ring 721 and a second cutting strip 722 arranged in the second cutting ring 721. The second cutting ring 721 is connected to the rotating drum 740. The first cutting ring 711 and the second cutting ring 721 are coaxially arranged.

[0056] Among them, the first cutting member 710 can rotate relative to the bracket 730 and the second cutting member 720, so that the first cutting strip 712 and the second cutting strip 722 can rotate relative to each other to cut the waste. Compared with the traditional rotating shaft cutting member, the problem of waste being entangled on the rotating shaft and unable to be cut and continuing to fall into the negative pressure chamber 100 can be avoided. Specifically, the rotating drum 740 is driven to rotate by the rotating driving member to rotate the second cutting ring 721.

[0057] In this embodiment, the contact edges of the first cutting ring 711 and the second cutting ring 721 are also respectively provided with a first cutting portion 713 and a second cutting portion 723 in the shape of an ridge. The waste material wrapped around the first cutting strip 712 and close to the end of the first cutting ring 711 will rub against the first cutting portion 713 or the second cutting portion 723 and break during the rotation of the first cutting strip 712, thereby improving the cutting effect of the waste material.

[0058] Furthermore, the pusher 800 is provided with a transfer chamber 810 and a pusher 820, the second pipe 220, the transfer chamber 810 and the negative pressure chamber 100 are connected in sequence, the transfer chamber 810 is used to receive waste materials, and the pusher 820 is used to push and hold the waste materials.

[0059] In this embodiment, the second pipe 220 is connected to the negative pressure chamber 100 through the transfer chamber 810. While providing negative pressure to the negative pressure chamber 100 and allowing the waste to be adsorbed from the waste pipe 400 to the negative pressure chamber 100, it is also beneficial to adsorb the waste from the negative pressure chamber 100 to the transfer chamber 810, thereby improving the waste transportation efficiency.

[0060] It should be noted that the second pipe 220 can be connected to any part of the transfer chamber 810. The specific connection position between the second pipe 220 and the transfer chamber 810 is not shown in the figure. As long as the second pipe 220 is connected to the transfer chamber 810, no specific limitation is made here.

[0061] Furthermore, a partition 830 is provided at the connection between the transfer chamber 810 and the negative pressure chamber 100. The partition 830 is used to connect or separate the transfer chamber 810 and the negative pressure chamber 100, and the partition 830 is usually used to separate the transfer chamber 810 and the negative pressure chamber 100 when the pusher 820 pushes the waste.

[0062] In this embodiment, the transfer chamber 810 is provided with a feed port 840 connected to the negative pressure chamber 100. A partition 830 is provided at the feed port 840, so that the feed port 840 is opened or closed by the partition 830 to separate the negative pressure chamber 100 and the transfer chamber 810, so as to avoid the pressure in the negative pressure chamber 100 being affected by the pressure of the transfer chamber 810 during the process of pushing and holding the waste.

[0063] It should be noted that, when the partition 830 closes the feed port 840 , the first pipeline 210 is usually opened and the second pipeline 220 is closed.

[0064] Furthermore, the transfer chamber 810 is also provided with a discharge port 850, and a baffle 860 is provided at the discharge port 850. The baffle 860 is closed when the feed port 840 is opened, so as to ensure that the transfer chamber 810 is not connected to the external environment during the process of waste entering the transfer chamber 810, thereby preventing the pressure in the negative pressure chamber 100 from being affected.

[0065] In this embodiment, the baffle 860 is arranged opposite to the stripping plate so that the push plate can push the push plate under the action of the driving member and compact the waste under the action of the stripping plate and the baffle 860. In this case, the baffle 860 is moved again to open the discharge port 850, and the waste is pushed out through the push plate.

[0066] Furthermore, the present invention also provides a waste suction control method, comprising the following steps:

[0067] S100, controlling one of the at least two negative pressure pipes 200 to provide negative pressure for the negative pressure chamber 100;

[0068] S200, when the air flow rate of the negative pressure pipe 200 responsible for providing negative pressure to the negative pressure chamber 100 is reduced to a preset value, the negative pressure pipe 200 is paused, and another negative pressure pipe 200 of at least two negative pressure pipes 200 is controlled to provide negative pressure to the negative pressure chamber 100.

[0069] In this embodiment, at least two negative pressure pipes 200 include a first pipe 210 or a second pipe 220, and the first pipe 210 or the second pipe 220 acts on the negative pressure chamber 100 to form a negative pressure state in the negative pressure chamber 100, or the first pipe 210 and the second pipe 220 act on the negative pressure chamber 100 at the same time to form a negative pressure state in the negative pressure chamber 100, so as to adsorb the waste in the waste pipe 400 into the negative pressure chamber 100; not only that, by setting the first pipe 210 and the second pipe 220, the other negative pressure pipe 200 can be opened when one of the negative pressure pipes 200 is blocked, so as to ensure that the waste suction work is carried out uninterruptedly and the waste suction efficiency is guaranteed, and the blocked negative pressure pipe 200 can be cleaned, so that there is no need to set a cleaning device to clean the first pipe 210 and the second pipe 220, thereby reducing production costs and improving production efficiency.

[0070] In summary, the embodiment of the present invention provides a waste suction device 10 and a control method, and a glue stripping machine. The glue tape pasted on the electrode material strip is usually peeled off by the glue stripping device and the winding device. The waste suction device 10 sucks and uniformly processes waste materials such as waste glue, which can effectively improve the waste treatment efficiency.

[0071] The first pipe 210 or the second pipe 220 , or the first pipe 210 and the second pipe 220 simultaneously act on the negative pressure chamber 100 to form a negative pressure state in the negative pressure chamber 100 , so that the waste in the waste pipe 400 is adsorbed into the negative pressure chamber 100 .

[0072] Moreover, by providing the first pipe 210 and the second pipe 220, when one of the pipes is blocked, the other pipe can be opened, thereby ensuring that the waste suction work is carried out uninterruptedly and the waste suction efficiency is ensured, and the blocked pipe or negative pressure chamber 100 can be cleaned, so there is no need to provide a cleaning device to clean the first pipe 210 and the second pipe 220, thereby reducing production costs and improving production efficiency.

[0073] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
