Abstract
Description
Technical Field
[0001] This utility model belongs to the field of battery manufacturing technology, and in particular relates to a dust removal device and dust removal system for a material belt. Background Technology
[0002] Currently, the main dust removal methods for lithium battery production strips include magnetic rod / magnetic plate dust removal (used to remove magnetic dust), positive pressure, negative pressure or positive / negative pressure combination dust removal (used to remove dust from the surface of the strip and air), and brush + negative pressure dust removal (used to remove dust adsorbed on the strip). These dust removal devices are installed independently in a certain order.
[0003] Typically, a demagnetizing mechanism is installed at the front end, a brush roller + negative pressure brush dust removal mechanism is installed in the middle, and an air knife dust removal mechanism with negative pressure or a combination of positive and negative pressure is installed at the rear end for final cleaning of the conveyor belt surface. This combination of dust removal mechanisms can effectively remove relatively loosely attached dust from the conveyor belt, but it is ineffective at removing strongly attached dust. There are two main reasons for this:
[0004] 1. Positive / negative pressure can affect the operation of the conveyor belt (excessive wind speed can cause the conveyor belt to vibrate);
[0005] 2. The friction generated by the rolling brush in contact with the moving material belt is very small, and the brush strips themselves have gaps, making it difficult to completely remove dust. Utility Model Content
[0006] The purpose of this utility model is to address the aforementioned technical problems by providing a dust removal device and system for conveyor belts. This dust removal device and system can first adhere and transfer the dust on the conveyor belt, and then remove the transferred dust, thereby improving the cleaning effect of the conveyor belt without affecting its operation.
[0007] In view of this, the present invention provides a dust collection device for conveyor belts, comprising:
[0008] The sticky roller is in contact with the surface of the material belt and can transfer dust from the surface of the material belt to its own surface.
[0009] The cleaning mechanism can create a low temperature on the surface of the sticky roller and separate the dust on the surface of the sticky roller from the sticky roller;
[0010] The negative pressure mechanism can suck away the dust that has detached from the sticky roller.
[0011] In this technical solution, the adhesive roller rotates during operation and comes into contact with the surface of the conveyor belt. When the adhesive roller comes into contact with the surface of the conveyor belt, it will stick to the dust on the surface of the conveyor belt. As the adhesive roller rotates, the surface of the adhesive roller with the sticky dust comes to the cleaning mechanism. The cleaning mechanism forms a low temperature on the surface of the adhesive roller, which temporarily reduces the viscosity of the surface of the adhesive roller. Then the cleaning mechanism separates the dust on the surface of the adhesive roller from the adhesive roller. Then the negative pressure mechanism is activated to suck away the dust that has detached from the adhesive roller. As the adhesive roller rotates, the surface of the adhesive roller after cleaning can come into contact with the conveyor belt again and stick to the dust on the surface of the conveyor belt. This process is repeated to remove dust from the surface of the conveyor belt.
[0012] In the above technical solution, the dust removal device further includes a housing with an inner cavity, and a negative pressure mechanism including a connection port. The connection port is disposed on the housing and communicates with the inner cavity. The connection port can be connected to a negative pressure source to form a negative pressure in the inner cavity. The viscous roller is rotatably connected in the inner cavity, and the viscous roller part extends out of the housing and contacts the surface of the material belt.
[0013] In the above technical solution, the cleaning mechanism further includes an air guide pipe, one end of which is located in the inner cavity of the housing and faces the viscous roller, and the other end of which is connected to an air source.
[0014] In the above technical solution, the gas source guide tube provides low-temperature and high-speed gas.
[0015] In the above technical solution, furthermore, the gas flow rate is greater than 30m / s.
[0016] In the above technical solution, the temperature range of the gas is further defined as 2–6°C.
[0017] In the above technical solution, the adhesive roller further includes a roller and a silicone layer, the roller is rotatably connected to the housing, and the silicone layer is sleeved on the outside of the roller.
[0018] This utility model also discloses a dust removal system, including two sets of the aforementioned dust removal devices, which are located on both sides of the material belt, and two viscous rollers in the two sets of dust removal devices are in contact with the two surfaces of the material belt respectively.
[0019] In the above technical solution, the dust removal system further includes a demagnetizing mechanism, a brush dust removal mechanism, and an air knife dust removal mechanism. The demagnetizing mechanism, the brush dust removal mechanism, and the air knife dust removal mechanism are distributed sequentially along the moving direction of the conveyor belt, and the two sets of dust removal devices are set on the side of the air knife dust removal mechanism away from the brush dust removal mechanism.
[0020] In the above technical solution, furthermore, multiple sets of guide rollers are arranged at intervals along the length of the material strip, and the guide rollers can change the moving direction of the material strip.
[0021] The beneficial effects of this utility model are:
[0022] 1. Through the cooperation of the adhesive roller, the cleaning mechanism, and the negative pressure mechanism, the adhesive roller can first transfer the dust on the surface of the material belt to its own surface, then the cleaning mechanism separates the dust from the adhesive roller, and then the negative pressure mechanism sucks away the dust to prevent the dust from adhering to the adhesive roller again. This method performs adhesive dust removal on the surface of the material belt, resulting in good dust removal effect.
[0023] 2. By designing the negative pressure mechanism as a housing with an inner cavity and a connecting port, and by creating negative pressure in the inner cavity through a negative pressure source, the viscous roller is connected to the inner cavity and partially extends out of the housing. The cleaning mechanism is designed as a combination of an air guide pipe and an air source, applying low-temperature and high-speed gas to the surface of the viscous roller away from the material belt. In this way, the gas blown onto the viscous roller can temporarily reduce the viscosity of the viscous roller surface and blow off the dust adhering to the surface of the viscous roller, so that the dust can be carried away by the negative pressure in the inner cavity. In this way, there is no positive pressure / negative pressure acting on the material belt, and the operation of the material belt will not be affected.
[0024] 3. By combining the demagnetizing mechanism, the brush dust removal mechanism, the air knife dust removal mechanism, and two sets of dust removal devices to form a dust removal system for the material belt, the dust on the material belt can be removed in a targeted manner, and the dust removal effect is good.
[0025] 4. By setting multiple sets of guide rollers to change the direction of the material belt movement, the overall space occupied by the dust removal system can be reduced, thus lowering space costs. Attached Figure Description

For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.

In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items, and therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.
[0036] Existing dust removal systems such as Figure 1 As shown, a demagnetizing mechanism 200 is installed at the front end, a brush dust removal mechanism 300 with brush roller and negative pressure is installed in the middle, and an air knife dust removal mechanism 400 with negative pressure or a combination of positive pressure and negative pressure is installed at the rear end to perform final cleaning on the surface of the material belt 100.
[0037] Example 1
[0038] like Figures 2-4 As shown, this embodiment provides a material belt dust removal device, including: a viscous roller 1, a cleaning mechanism, a negative pressure mechanism, and a housing 2;
[0039] In this embodiment, please refer to Figure 2 The viscous roller 1 extends out of the housing 2 and can contact the surface of the material belt 100. The cleaning mechanism and the negative pressure mechanism are both set in the housing 2. The outer wall of the housing 2 is provided with a motor 6 that can drive the viscous roller 1 to rotate.
[0040] Please refer to the details. Figure 3 or Figure 4 The housing 2 has an inner cavity 201. The adhesive roller 1 includes a roller 101 and an adhesive layer. The adhesive layer is sleeved on the outside of the roller 101. The roller 101 is rotatably connected to the inner wall of the housing 2 through a drive shaft 5. One end of the drive shaft 5 passes through the inner wall of the housing 2 and is connected to the output shaft of the motor 6. The adhesive layer is an adhesive material that can adsorb dust in the prior art, such as silicone. In the following text, the adhesive layer is taken as silicone layer 102. When the adhesive roller 1 contacts the surface of the material belt 100, as the adhesive roller 1 rotates, the silicone layer 102 can transfer the dust on the surface of the material belt 100 to its own surface.
[0041] In this embodiment, the cleaning mechanism can create a low temperature on the surface of the adhesive roller 1 and separate the dust on the surface of the adhesive roller 1 from the adhesive roller 1. For details, please refer to [link to relevant documentation]. Figure 3 The cleaning mechanism includes an air guide pipe 4. One end of the air guide pipe 4 is located in the inner cavity 201 of the housing 2 and faces the adhesive roller 1. The other end of the air guide pipe 4 is connected to an air source (not shown in the figure). The air source can provide low-temperature and high-speed gas to the air guide pipe 4. The gas can act on a part of the surface of the silicone layer 102 of the adhesive roller 1. The low-temperature airflow can temporarily reduce the viscosity of the surface of the silicone layer 102, while the high-speed airflow can blow off the dust in the area of reduced viscosity on the silicone layer 102, so that the dust falls into the inner cavity 201.
[0042] In this embodiment, the air source can be a combination of a commercially available air compressor and a refrigeration device;
[0043] As a preferred embodiment, the gas provided by the gas source guide pipe 4 has a flow rate greater than 30 m / s and a gas temperature range of 2 to 6°C.
[0044] In this embodiment, the negative pressure mechanism can suck away the dust that has detached from the sticky roller 1. For details, please refer to [link / reference needed]. Figure 2 The negative pressure mechanism includes a connection port 3, which is disposed on the housing 2 and communicates with the inner cavity 201. The connection port 3 can be connected to a negative pressure source (not shown in the figure) to form a negative pressure in the inner cavity 201. After dust falls into the inner cavity 201, the dust can be discharged from the inner cavity 201 through the connection port 3 under the action of negative pressure, thus preventing subsequent dust from being re-adsorbed onto the silicone layer 102 of the adhesive roller 1.
[0045] In this embodiment, the negative pressure source can be a commercially available air compressor or other similar product.
[0046] In this embodiment, the dust removal device 600 is installed on one side of the conveyor belt 100, so that the circumferential surface of the adhesive roller 1 contacts the surface of the conveyor belt 100. During the movement of the conveyor belt 100, the adhesive roller 1 rotates and transfers the dust on the surface of the conveyor belt 100 to its own silicone layer 102 surface. The dust is transferred to the cleaning mechanism along with the adhesive roller 1. The cleaning mechanism blows low-temperature and high-speed gas onto the surface of the silicone layer 102, so that the dust adhering to the surface of the silicone layer 102 is separated from the silicone layer 102 and discharged from the inner cavity 201 through the connection port 3 under the action of negative pressure in the inner cavity 201. During the dust removal operation, the air source continuously provides low-temperature and high-speed gas to the air guide pipe 4, and the negative pressure source continuously forms negative pressure in the inner cavity 201, which can continuously remove the dust adhering to the adhesive roller 1. This setting not only improves the dust removal effect of the conveyor belt 100, but also avoids directly applying positive / negative pressure to the conveyor belt 100, thus not affecting the operation of the conveyor belt 100.
[0047] Example 2
[0048] This embodiment provides a dust removal system that adds a contact dust removal device 600 to the existing dust removal system to remove adhesive dust from the surface of the conveyor belt 100.
[0049] In this embodiment, the contact dust removal device 600 includes two sets of dust removal devices 600 as described in the previous embodiments;
[0050] Please refer to the details. Figure 5 The demagnetizing mechanism 200, the brush dust removal mechanism 300, and the air knife dust removal mechanism 400 are distributed sequentially along the moving direction of the material belt 100. Two sets of dust removal devices 600 are set on the side of the air knife dust removal mechanism 400 away from the brush dust removal mechanism 300. The two sets of dust removal devices 600 are located on both sides of the material belt 100. The two sticky rollers 1 in the two sets of dust removal devices 600 are in contact with the two surfaces of the material belt 100 respectively.
[0051] In this embodiment, the demagnetizing mechanism 200, the brush dust removal mechanism 300, and the air knife dust removal mechanism 400 can all adopt the structure in the prior art. For example, the demagnetizing mechanism 200 can use magnetic rod / magnetic plate dust removal, the brush dust removal mechanism 300 can use a combination of brush roller + negative pressure dust removal, and the air knife dust removal mechanism 400 can use a combination of negative pressure or positive pressure + negative pressure dust removal.
[0052] In this embodiment, when the dust removal system removes dust from the conveyor belt 100, the demagnetizing mechanism 200 first removes magnetic dust from the surface of the conveyor belt 100, then the brush dust removal mechanism 300 removes floating dust from the surface of the conveyor belt 100 and the air, then the air knife dust removal mechanism 400 removes relatively weak dust adsorbed on the surface of the conveyor belt 100, and finally the contact dust removal device 600 removes relatively strong dust adsorbed on the surface of the conveyor belt 100; thereby achieving efficient dust removal of the conveyor belt 100.
[0053] Example 3
[0054] This embodiment provides a dust removal system. Based on embodiment 2, multiple sets of guide rollers 500 are arranged at intervals along the length of the material belt 100. The guide rollers 500 can change the moving direction of the material belt 100.
[0055] Please see Figure 5 The guide roller 500 rotates the material belt 100 by 90 degrees. This shortens the distance between adjacent dust removal mechanisms when dust removal is performed on material belts 100 of the same length, thereby reducing the overall space occupied by the dust removal system and lowering space costs.
[0056] The embodiments of the present invention have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
