Description

Technical Field

[0001] This utility model relates to the technical field of battery electrode manufacturing equipment, specifically a novel residual paste blowing nozzle. Background Technology

[0002] During the manufacturing process of battery plates, a plate coating process is required. Residual coating may remain at the R-angle of the tabs. This residual coating is removed by using compressed air nozzles.

[0003] In existing technologies, residual paint is removed using a single-outlet nozzle. This single-outlet nozzle sprays at a fixed point, which is prone to leaving residue due to electrode plate position deviation or paint viscosity, resulting in incomplete cleaning. Furthermore, the nozzle is directly connected to the air source, and the pressure fluctuates with the pipeline network, leading to unstable airflow and uneven purging force. It is also impossible to adjust the spray angle according to the residue accumulation pattern. This application proposes a novel residual paint blowing nozzle that achieves efficient cleaning through air chamber pressure stabilization and dual-path coordinated spraying. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a novel residual paste blowing nozzle, which solves the problems of single-outlet nozzles that spray at a fixed single point, easily leaving residual material due to electrode plate position deviation or coating viscosity, resulting in incomplete cleaning; and the nozzles that are directly connected to the air source, causing pressure fluctuations with the pipeline network and unstable airflow, resulting in uneven blowing force, and the inability to adjust the spray angle according to the residual material accumulation pattern.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel residual paste blowing nozzle, comprising:

[0006] The main body of the dual-outlet air nozzle has a cylindrical air chamber in the middle.

[0007] An air inlet is located at the top of the dual-outlet air nozzle body. The air inlet is connected to the air chamber, and its axis is perpendicular to the central axis of the air chamber.

[0008] Two nozzle bodies are located at the bottom of the dual-outlet air nozzle body. The nozzle bodies are connected to the air chamber. The nozzle bodies are divided into a front nozzle and a rear nozzle, which are arranged horizontally.

[0009] Preferably, the dual-outlet nozzle body is provided with a mounting base, which is inserted into the intake valve.

[0010] Preferably, the mounting base has a mounting hole, and the mounting hole is fixed to the air intake valve by bolts.

[0011] Preferably, the nozzle body is slidably connected in the dual-outlet nozzle body.

[0012] Preferably, the dual-outlet nozzle body has an adjustment hole, which is provided corresponding to the nozzle body.

[0013] Preferably, a connecting pipe is sleeved on the outer peripheral wall of the nozzle body.

[0014] Preferably, the bottom end of the connecting pipe is provided with a fixing pipe, which is bent.

[0015] Preferably, a fixing seat is fixedly connected to the top end face of the connecting pipe, the fixing seat is arranged corresponding to the nozzle body, and a bolt is provided in the fixing seat.

[0016] This utility model discloses a novel residual paste blowing nozzle, which has the following beneficial effects:

[0017] In this new type of residual paste blowing nozzle, compressed air enters the air chamber tangentially through the air inlet valve. After the swirling deceleration, the pressure fluctuation is reduced. The airflow is split into two paths and ejected from the front nozzle and the rear nozzle. At the same time, a secondary purging is carried out under the action of the front nozzle and the rear nozzle, so that the residual material rate is low.

[0018] When gas enters the cylindrical cavity tangentially, it is constrained by the cavity wall and generates an angular momentum conservation effect, forming a high-speed rotating flow field. The rotating airflow gathers towards the cavity wall under the action of centrifugal force, and a low-pressure cavity is formed in the central region. This process can effectively attenuate pressure pulsation. Due to rotational inertia, the fluid kinetic energy is converted into stable potential energy, thereby suppressing pressure fluctuations and ensuring the uniformity of the purging force through the nozzle body.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] This application embodiment solves the problems of single-outlet nozzles spraying at a fixed point, which are prone to residual material due to electrode plate position deviation or coating viscosity, resulting in incomplete cleaning. In addition, the nozzle is directly connected to the air source, and the pressure fluctuates with the pipeline network, resulting in unstable airflow and uneven purging force. Furthermore, it is impossible to adjust the spray angle according to the residual material accumulation pattern. The embodiment achieves that compressed air enters the air chamber 11 tangentially through the air inlet valve. After the swirling deceleration, the pressure fluctuation is reduced. The airflow is split into two paths and ejected from the front nozzle and the rear nozzle. At the same time, a secondary purging is performed under the action of the front nozzle and the rear nozzle, resulting in a lower residual material rate.

[0027] When gas enters the cylindrical cavity tangentially, it is constrained by the cavity wall and generates an angular momentum conservation effect, forming a high-speed rotating flow field. The rotating airflow gathers towards the cavity wall under the action of centrifugal force, and a low-pressure cavity is formed in the central region. This process can effectively attenuate pressure pulsation. Due to rotational inertia, the fluid kinetic energy is converted into stable potential energy, thereby suppressing pressure fluctuations and ensuring the uniformity of the purging force through the nozzle body 4.

[0028] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0029] This utility model discloses a novel residual paste blowing nozzle.

[0030] Example 1, according to Appendix Figure 1-4 As shown, it includes:

[0031] The main body 1 of the dual-outlet air nozzle has a cylindrical air chamber 11 in its middle;

[0032] An air inlet 3 is located at the top of the dual-outlet nozzle body 1. The air inlet 3 is connected to the air chamber 11, and its axis is perpendicular to the central axis of the air chamber 11. One end of the air inlet 3 is connected to compressed air.

[0033] Two nozzle bodies 4 are located at the bottom of the dual-outlet air nozzle body 1. The nozzle bodies 4 are connected to the air chamber 11. The nozzle bodies 4 are divided into a front nozzle and a rear nozzle, which are arranged horizontally.

[0034] Compressed air enters the air chamber 11 tangentially through the air inlet valve. After the swirling deceleration, the pressure fluctuation is reduced by 60% to 70%. The airflow is split into two paths and ejected from the front nozzle and the rear nozzle. At the same time, a secondary purging is carried out under the action of the front nozzle and the rear nozzle, so that the residual material rate is reduced from 12% of the single nozzle to below 3%.

[0035] The structure of air chamber 11 reduces the outlet pressure fluctuation range from ±0.15MPa to ±0.03MPa. When the gas enters the cylindrical cavity from the tangential direction, it is constrained by the cavity wall and generates an angular momentum conservation effect, forming a high-speed rotating flow field. The rotating airflow gathers towards the cavity wall under the action of centrifugal force, and a low-pressure cavity is formed in the central region. This process can effectively attenuate pressure pulsation. Due to the rotational inertia, the fluid kinetic energy is converted into stable potential energy, thereby suppressing pressure fluctuations and ensuring the uniformity of the purging force through the nozzle body 4.

[0036] The nozzle body has a cylindrical cavity in the middle with a diameter D=10-20mm and a height H=20-40mm. The air inlet holes are connected tangentially to form a swirling pressure stabilization.

[0037] The main body 1 of the dual-outlet air nozzle is provided with a mounting base 2, which is inserted into the air intake valve.

[0038] Mounting base 2 has mounting holes 21, which are fixed to the air intake valve by bolts.

[0039] Mounting seat 2 is fixed to the intake valve by threads, so that the dual-outlet air nozzle body 1 is installed by bolts. By adjusting the bolts on both sides of mounting seat 2, mounting seat 2 is separated from the intake valve. At this time, mounting seat 2 and intake valve can be adjusted to offset mounting seat 2 on the intake valve; mounting seat 2 can be adjusted radially by ±5mm and axially by 10°.

[0040] When the position of the mounting base 2 is adjusted radially, and the angle of the mounting base 2 is adjusted, the position of the nozzle body 4 installed below the mounting base 2 is adjusted to adapt to various situations of residual paste blowing off the electrode plate.

[0041] The nozzle body 4 is slidably connected to the dual-outlet nozzle body 1.

[0042] By adjusting the height of the two nozzle bodies 4, the position of the nozzle body 4 relative to the electrode plate is adjusted, thereby adjusting the spray coverage area from the nozzle body 4 so that the coverage areas can overlap by 20% to 40%, or by adjusting downwards so that the spray coverage areas of the nozzle body 4 are completely separated.

[0043] An adjustment hole 41 is provided on the main body 1 of the dual-outlet air nozzle, and the adjustment hole 41 is set corresponding to the nozzle body 4.

[0044] By threading a screw into the adjusting hole 41, the nozzle body 4 is squeezed by the adjusting screw, thereby adjusting the position of the nozzle body 4 in the dual-outlet air nozzle body 1. The spacing of the nozzle body 4 can be changed by adjusting the screw, and the spacing can be adjusted from 5 to 15 mm to adapt to different viscosity coatings.

[0045] During installation, the bolt can slide ±5mm within the adjustment hole 41. After adjustment, it is locked with a nut. This design utilizes the precise fit between the bolt rod and the adjustment hole 41 to achieve radial displacement while ensuring shear strength.

[0046] Example 2, according to Appendix Figure 1-4 As shown, it includes:

[0047] The main body 1 of the dual-outlet air nozzle has a cylindrical air chamber 11 in its middle;

[0048] An air inlet 3 is located at the top of the dual-outlet air nozzle body 1. The air inlet 3 is connected to the air chamber 11, and the axis of the air inlet 3 is perpendicular to the central axis of the air chamber 11.

[0049] Two nozzle bodies 4 are located at the bottom of the dual-outlet air nozzle body 1. The nozzle bodies 4 are connected to the air chamber 11. The nozzle bodies 4 are divided into a front nozzle and a rear nozzle, which are arranged horizontally.

[0050] A connecting pipe 5 is sleeved on the outer peripheral wall of the nozzle body 4.

[0051] By adjusting the connecting pipe 5 which is sleeved on the nozzle body 4, the jet outlet of the airflow ejected from the nozzle body 4 can be adjusted, thereby adjusting the jet coverage area of ​​the two nozzle bodies 4.

[0052] A fixing pipe is provided at the bottom end of the connecting pipe 5, and the fixing pipe is bent.

[0053] By bending the bottom of the connecting pipe 5, the spray angle of the airflow is adjusted. Under the action of the connecting pipe 5, the airflow is sprayed through the connecting pipe 5 in conjunction with the nozzle body 4. The angle of the front nozzle is adjusted and fixed as needed to blow away the residual material for the first time.

[0054] The airflow is sprayed through the connecting pipe 5 in conjunction with the nozzle body 4. The angle of the rear nozzle is adjusted and fixed as needed to blow away the remaining material a second time.

[0055] The positions of the front and rear nozzles can be combined in various ways to blow air away residual paste from the electrode plates in various situations.

[0056] Adjust the spray angle according to the shape of the residual material accumulation, and adapt to the cleaning needs of different tab R angles by adjusting the nozzle angle.

[0057] A fixing seat 51 is fixedly connected to the top end face of the connecting pipe 5. The fixing seat 51 is set corresponding to the nozzle body 4, and a bolt is installed in the fixing seat 51.

[0058] The connecting pipe 5 and the nozzle body 4 can be easily installed using the bolts on the fixing seat 51. When the connecting pipe 5 is adjusted to a suitable angle, the fixing seat 51 and the nozzle body 4 can be fixed using the bolts. The positions of the front nozzle and the rear nozzle can be combined in various ways to blow air away residual paste from the electrode plate in various situations.
