Description

Technical Field

[0001] This utility model relates to the field of lithium battery separator technology, and in particular to the heating pack mechanism of a lithium battery separator coating machine. Background Technology

[0002] Lithium-ion battery separator coating is a crucial step in lithium-ion battery manufacturing, significantly impacting battery performance and safety. The basic principle of the coating process is to apply a layer of material to the separator to prevent direct contact between the positive and negative electrodes, thus preventing short circuits. During coating, it is essential to ensure the separator evenly covers the surfaces of both electrodes and to control the appropriate amount of adhesive applied. The coating process generally includes preparation, coating operation, drying, and inspection and quality control.

[0003] In the process of coating and drying lithium battery separators, the coated separators are usually placed in an oven for drying. However, toxic and harmful gases are generated during the drying process. If these toxic and harmful gases circulate in the oven, they will remain inside the oven. In addition, lithium battery separators are usually placed on drying trays during drying. The number of drying trays is limited, so a heating pack mechanism is needed for the lithium battery separator coating machine. Utility Model Content

[0004] The purpose of this invention is to provide a heating pack mechanism for a lithium battery separator coating machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heating pack mechanism for a lithium battery separator coating machine, comprising a base, a heating box fixedly mounted on the upper surface of the base, a drying mechanism disposed inside the heating box, a drain pipe fixedly mounted on one side of the heating box, a support column fixedly mounted on the upper surface of the base, a storage mechanism disposed on the top of the support column, an air outlet plate fixedly mounted on the top of the storage mechanism, a support bar fixedly mounted on the storage mechanism, a rotating rod fixedly mounted inside the support bar, a torsion spring fixedly mounted on the support bar, a rotating plate rotatably mounted on the rotating rod, the other end of the torsion spring fixedly mounted on the rotating plate, and a pull block fixedly mounted on the outer side of the rotating plate.

[0006] Preferably, the drying mechanism includes a heating pack fixed to the upper surface of the base, the heating pack being fixedly installed on one side of the heating box, a water outlet box being fixedly installed on the other side of the heating pack, and a heating tube being fixedly installed on the heating pack.

[0007] Preferably, a first rotating shaft is rotatably mounted inside the heating box, a first fan blade is fixedly mounted on the first rotating shaft, a first pulley is fixedly mounted on the first rotating shaft, a belt is sleeved on the first pulley, a support is fixedly mounted on the upper surface of the base, a second rotating shaft is rotatably mounted inside the support, the second rotating shaft is rotatably mounted inside the heating box, a second pulley is fixedly mounted on the second rotating shaft, a belt is sleeved on the second pulley, and a second fan blade is fixedly mounted on the second rotating shaft.

[0008] Preferably, a fixing block is fixedly installed inside the heating box, and the heating tube is fixedly installed inside the fixing block.

[0009] Preferably, a motor box is fixedly mounted on the upper surface of the base, and the first rotating shaft is fixedly mounted on the output end of the motor box.

[0010] Preferably, a sliding sleeve is fixedly installed on the upper surface of the base, the first rotating shaft is rotatably installed inside the sliding sleeve, and a limit block is fixedly installed on the second rotating shaft.

[0011] Preferably, the storage mechanism includes a storage box fixedly installed on the top of the support column, a support rod fixedly installed inside the storage box, a first connecting strip fixedly installed on the support rod, a connecting plate fixedly installed on the first connecting strip, and an air inlet plate fixedly installed inside the storage box.

[0012] The beneficial effects of this utility model are:

[0013] In this invention, the drying mechanism is designed such that the heating pack is activated first to heat the water in the heating tube, and then the motor box is activated to drive the first rotating shaft to rotate. The rotation of the first rotating shaft drives the first and second fan blades to rotate, and the rotation of the first and second fan blades generates airflow, which blows the heat generated by the heating tube onto the lithium battery film in the storage mechanism. The exhaust plate is then connected to the exhaust gas treatment mechanism. In this way, the lithium battery film can be dried, and the toxic and harmful gases generated during the drying process can be treated.

[0014] In this invention, through the structural design of the storage mechanism, pulling the pull block causes the rotating plate to unfold, and multiple support rods, the first connecting strip, and the connecting plate form a multi-layer storage rack. Multiple lithium battery films are placed into the gaps of the storage rack. When the pull block is released, due to the torsion spring, the rotating plate will rotate back to its original position to cover the lithium battery films. This design allows multiple lithium battery films to be dried simultaneously, resulting in a better drying effect. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example:

[0022] like Figure 1-4 As shown, this embodiment provides a heating pack mechanism for a lithium battery separator coating machine, including a base 1, a heating box 2 fixedly installed on the upper surface of the base 1, a drying mechanism 3 provided inside the heating box 2, a drain pipe 4 fixedly installed on one side of the heating box 2, a support column 5 fixedly installed on the upper surface of the base 1, a storage mechanism 6 provided on the top of the support column 5, an air outlet plate 7 fixedly installed on the top of the storage mechanism 6, a support bar 8 fixedly installed on the storage mechanism 6, a rotating rod 9 fixedly installed inside the support bar 8, a torsion spring 10 fixedly installed on the support bar 8, a rotating plate 11 rotatably installed on the rotating rod 9, the other end of the torsion spring 10 fixedly installed on the rotating plate 11, and a pull block 12 fixedly installed on the outer side of the rotating plate 11.

[0023] Pull the lever 12, which will cause the rotating plate 11 to unfold. Then place the lithium battery film in the storage mechanism 6. Release the lever 12. Due to the setting of the torsion spring 10, the rotating plate 11 will rotate back to its original position and cover the lithium battery film. Then drive the drying mechanism 3. The drying mechanism 3 will generate hot air to dry the lithium battery film in the storage mechanism 6. Connect the air outlet plate 7 to the exhaust gas treatment mechanism to treat the harmful gases generated during drying. The drain pipe 4 can drain the condensate generated in the heating box 2 during cooling.

[0024] In this embodiment of the utility model, specifically, the drying mechanism 3 includes a heating pack 31 fixed to the upper surface of the base 1, the heating pack 31 is fixedly installed on one side of the heating box 2, the other side of the heating pack 31 is fixedly installed with a water outlet box 32, the heating pack 31 is fixedly installed with a heating tube 33, a first rotating shaft 34 is rotatably installed inside the heating box 2, a first fan blade 35 is fixedly installed on the first rotating shaft 34, a first pulley 36 is fixedly installed on the first rotating shaft 34, a belt 37 is sleeved on the first pulley 36, a support 38 is fixedly installed on the upper surface of the base 1, a second rotating shaft 39 is rotatably installed inside the support 38, the second rotating shaft 39 is rotatably installed inside the heating box 2, a second pulley 310 is fixedly installed on the second rotating shaft 39, the belt 37 is sleeved on the second pulley 310, and a second fan blade 311 is fixedly installed on the second rotating shaft 39.

[0025] To dry the lithium battery film, the heating pack 31 is first activated to heat the water in the heating tube 33. Then, the first rotating shaft 34 is rotated, which drives the first fan blade 35 to rotate. Simultaneously, the rotation of the first rotating shaft 34 drives the first pulley 36 to rotate, which in turn drives the belt 37 to rotate. The belt 37 then drives the second pulley 310 to rotate, which in turn drives the second rotating shaft 39 to rotate. The rotation of the second rotating shaft 39 then drives the second fan blade 311 to rotate. The rotation of the first fan blade 35 and the second fan blade 311 generates airflow, which blows the heat generated by the heating tube 33 onto the lithium battery film inside the storage mechanism 6. The exhaust plate 7 is then connected to the exhaust gas treatment mechanism. In this way, the lithium battery film can be dried, and the toxic and harmful gases generated during the drying process can be treated.

[0026] In this embodiment of the utility model, a fixing block 312 is fixedly installed inside the heating box 2, the heating tube 33 is fixedly installed inside the fixing block 312, the motor box 313 is fixedly installed on the upper surface of the base 1, the first rotating shaft 34 is fixedly installed on the output end of the motor box 313, the sliding sleeve 314 is fixedly installed on the upper surface of the base 1, the first rotating shaft 34 is rotatably installed inside the sliding sleeve 314, and a limit block 315 is fixedly installed on the second rotating shaft 39.

[0027] The fixing block 312 can fix the heating tube 33 inside the heating box 2. The motor box 313 can provide power to the first rotating shaft 34 and drive the first rotating shaft 34 to rotate. The sliding sleeve 314 can restrict the position of the first rotating shaft 34 so that the first rotating shaft 34 can only rotate within the sliding sleeve 314. The limiting block 315 can restrict the position of the second rotating shaft 39 and prevent the second rotating shaft 39 from moving out of the support 38.

[0028] In this embodiment of the utility model, specifically, the storage mechanism 6 includes a storage box 61 fixedly installed on the top of the support column 5, a support rod 62 fixedly installed inside the storage box 61, a first connecting strip 63 fixedly installed on the support rod 62, a connecting plate 64 fixedly installed on the first connecting strip 63, and an air inlet plate 65 fixedly installed inside the storage box 61.

[0029] In order to dry multiple lithium battery films at the same time, multiple support rods 62, first connecting strips 63 and connecting plates 64 form a multi-layer shelf. Multiple lithium battery films are placed in the gaps of the shelf to dry them at the same time. The air inlet plate 65 can be connected to the heating box 2 so that hot air can enter the placement box 61.

[0030] Working principle: In use, first start the heating pack 31, which heats the water in the heating tube 33. Then start the motor box 313, which drives the first rotating shaft 34 to rotate. The rotation of the first rotating shaft 34 drives the first fan blade 35 to rotate. At the same time, the rotation of the first rotating shaft 34 drives the first pulley 36 to rotate. The rotation of the first pulley 36 drives the belt 37 to rotate. The rotation of the belt 37 drives the second pulley 310 to rotate. The rotation of the second pulley 310 drives the second rotating shaft 39 to rotate. The rotation of the second rotating shaft 39 drives the second fan blade 311 to rotate. The rotation of the first fan blade 35 and the second fan blade 311 generates wind power, which... The heat generated by the heating tube 33 is blown onto the lithium battery film inside the storage mechanism 6. The exhaust plate 7 is connected to the exhaust gas treatment mechanism, which can dry the lithium battery film and treat the toxic and harmful gases generated during drying. Pulling the pull block 12 causes the rotating plate 11 to unfold. Multiple support rods 62, the first connecting strip 63 and the connecting plate 64 form a multi-layer storage rack. Multiple lithium battery films are placed into the gaps of the storage rack. Releasing the pull block 12 causes the rotating plate 11 to rotate back to its original position and cover the lithium battery film due to the setting of the torsion spring 10. This setting can dry multiple lithium battery films at the same time, and the drying effect is better.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
