Description

Technical Field

[0001] This utility model relates to the field of material suction equipment technology, and in particular to a suction gun mechanism and a material suction device. Background Technology

[0002] The raw materials for lithium battery slurry can be divided into powder materials and liquid materials. The lithium battery slurry preparation process mainly involves uniformly dispersing powder materials such as active materials, conductive agents, and binders in a solvent to obtain a uniform and stable slurry for electrode coating. During the production process, the powder materials need to be added to the liquid system for uniform dispersion.

[0003] In existing technologies, a suction gun mechanism is typically used to draw powder materials into a vacuum feeder and discharge them into a receiving device.

[0004] In actual production, powder materials are usually packaged in soft material bags (specifically plastic bags). When using a suction gun mechanism to pick up the material, the plastic bag film is very easy to block the suction gun mechanism, causing the powder material to be unable to smoothly enter the suction device through the suction gun nozzle, resulting in reduced powder material conveying efficiency, and may even damage the suction gun mechanism, affecting subsequent work.

[0005] Therefore, there is an urgent need for a suction gun mechanism and a suction device to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a suction gun mechanism and a suction device to solve the problem of soft material bags clogging the suction components, ensure the continuity of powder material feeding, and improve the conveying efficiency of powder materials.

[0007] To achieve the above objectives, the following technical solution is provided:

[0008] A suction gun mechanism, comprising:

[0009] The suction device has one end inserted into the powder material in the flexible material bag;

[0010] A suction port is provided on the suction element and is located at the end of the suction element into which the powder material is inserted;

[0011] The air blowing pipe is connected to the suction component;

[0012] A one-way mechanism, located at the connection between the air blowing pipe and the suction component, is configured to allow airflow to flow only from the air blowing pipe toward the suction component.

[0013] As an optional solution, the suction element is tubular, and the inner diameter of the suction element is D1, wherein 10mm≦D1≦100mm.

[0014] As an optional solution, the suction port includes multiple auxiliary feeding holes, which are arranged at intervals along the axial and / or circumferential direction of the suction element.

[0015] As an optional feature, the diameter of the auxiliary feed hole is d, where 1mm ≤ d ≤ 10mm.

[0016] As an optional solution, the air blowing pipe is disposed on the side wall of the suction element and is disposed at the end of the suction element away from the powder material.

[0017] As an optional feature, the inner diameter of the air blowing pipe is D2, where 5mm ≤ D2 ≤ 50mm.

[0018] As an alternative, the end of the air blowing pipe away from the suction element is positioned downwards.

[0019] As an optional solution, a detection element is provided inside the suction element, the detection element is configured to detect the air pressure inside the suction element, and the one-way mechanism is electrically connected to the detection element.

[0020] As an optional solution, the suction component has one end of the suction port as a nozzle, and the cross-sectional shape of the nozzle is rectangular, trapezoidal or conical.

[0021] A material suction device includes an air blowing mechanism and a material suction mechanism, and also includes the aforementioned suction gun mechanism. The air blowing mechanism is connected to the end of the air blowing pipe away from the material suction component, and the material suction mechanism is connected to the end of the material suction component away from the powder material.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] The suction gun mechanism provided by this utility model stops working when the suction port is blocked by a soft-pack material bag. The blowing mechanism blows air into the soft-pack material bag through the blowing pipe to separate the soft-pack material bag blocking the suction port from the suction component, thereby solving the problem that soft-pack material bags easily block the suction component, ensuring the continuity of powder material feeding, and improving the conveying efficiency of powder material. By setting a one-way mechanism, the gas can achieve one-way flow from the blowing pipe to the suction component, preventing powder material from entering the blowing pipe.

[0024] The suction device provided by this utility model, by applying the above-mentioned suction gun mechanism, can prevent soft material bags from clogging the suction component, thereby ensuring the continuity of powder material feeding and improving the conveying efficiency of powder materials.

[0042] Example 1

[0043] This embodiment provides a feeding device for feeding powder material 200. Specifically, as shown... Figure 1 As shown, the material suction device includes a suction gun mechanism 100 and a material suction mechanism (not shown in the figure). The suction gun mechanism 100 includes a suction element 10, which has a suction port 111. One end of the suction element 10 with the suction port 111 is inserted into the powder material 200 inside the flexible material bag 300. The material suction mechanism is used to evacuate air from the suction element 10 so that the suction port 111 can suck up the powder material 200, thereby completing the feeding of the powder material 200. The material suction mechanism can be an existing vacuum feeder, etc.

[0044] In actual production, powder material 200 is usually packaged in soft material bag 300 (specifically plastic bag). When the suction gun mechanism 100 is used to suction the material, the plastic bag film is very easy to block the suction port 111, causing the powder material 200 to be unable to smoothly enter the suction component 10 through the suction port 111, resulting in a reduction in the conveying efficiency of the powder material 200 and affecting subsequent work.

[0045] To solve the above problems, such as Figure 1 and Figure 2 As shown, the suction gun mechanism 100 provided in this embodiment also includes an air blowing pipe 20 and a one-way mechanism 30, and the suction device also includes an air blowing mechanism. The air blowing pipe 20 is connected to the suction component 10. The air blowing mechanism is used to blow air into the soft-pack material bag 300 through the air blowing pipe 20. The one-way mechanism 30 is configured to allow the airflow to flow only from the air blowing pipe 20 towards the suction component 10. The air blowing mechanism can be an existing blower or a vacuum breaking machine.

[0046] When the suction port 111 is blocked by the soft-pack material bag 300, the suction mechanism stops working, and the blowing mechanism blows air into the soft-pack material bag 300 through the blowing pipe 20 to separate the soft-pack material bag 300 blocking the suction port 111 from the suction component 10, thereby solving the problem of the soft-pack material bag 300 blocking the suction component 10, ensuring the continuity of powder material 200 feeding, and improving the conveying efficiency of powder material 200; by setting a one-way mechanism 30, the gas can achieve one-way flow from the blowing pipe 20 to the suction component 10, preventing powder material 200 from entering the blowing pipe 20.

[0047] In this embodiment, the one-way mechanism 30 is a diaphragm valve, which is located at the connection between the air blowing pipe 20 and the suction member 10. During forward flow, the forward airflow presses against the center of the diaphragm valve, causing it to bend towards the outlet side, forming a channel that connects the air blowing pipe 20 and the suction member 10. During reverse flow, the diaphragm valve returns to its flat state, sealing against the air blowing pipe 20. In other embodiments, the one-way mechanism 30 can be a solenoid valve. The suction gun mechanism 100 also includes a control component electrically connected to the solenoid valve. When air needs to be blown into the suction member 10, the control component controls the solenoid valve to open, allowing the air blowing pipe 20 to blow air into the suction member; when air does not need to be blown into the suction member 10, the control component controls the solenoid valve to close. It should be noted that the control component is prior art, and its working principle and specific structure will not be described in detail.

[0048] Optionally, a detection element is provided inside the suction component 10. The detection element is configured to detect the air pressure inside the suction component 10. The one-way mechanism 30 is electrically connected to the detection element. The control component can control the opening or closing of the one-way mechanism 30 according to the value detected by the detection element. In this embodiment, when the detection element detects that the pressure value inside the suction component 10 is lower than 15 kPa, the control component controls the one-way mechanism 30 to open the air blowing pipe 20 and the suction component 10 to blow air into the suction component 10, so as to separate the flexible material bag 300 from the suction component 10 and prevent the flexible material bag 300 from blocking the suction component 10. The detection element can be a pressure sensor.

[0049] Optionally, the suction element 10 is tubular, with an inner diameter of D1, which is greater than or equal to 10 mm and less than or equal to 100 mm. This dimensional setting ensures a certain suction force while achieving good flow characteristics, preventing the inner diameter of the suction element 10 from being too small, resulting in significant suction loss, and simultaneously preventing the inner diameter from being too large, resulting in weakened suction. For example, the inner diameter D1 of the suction element 10 can be 10 mm, 20 mm, 30 mm, 40 mm, 50 mm, 60 mm, 70 mm, 80 mm, 90 mm, or 100 mm. Of course, in other embodiments, the value of D1 is not limited to these values, and designers can make adaptive selections according to actual needs.

[0050] Optionally, the suction port 111 includes a plurality of auxiliary feed holes 1111, which are arranged at intervals along the axial and / or circumferential directions of the suction member 10 to improve the suction efficiency of the suction member 10, enhance the uniformity of suction, and reduce the risk of clogging the suction port 111.

[0051] Optionally, the aperture of the auxiliary feed hole 1111 is d, which is greater than or equal to 1 mm and less than or equal to 10 mm, to accommodate different material particle sizes and avoid sucking in oversized particles or foreign objects. For example, the aperture d of the auxiliary feed hole 1111 can be 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm. Of course, in other embodiments, the value of d is not limited to this, and designers can make an adaptive selection according to actual needs.

[0052] Optionally, a filter screen is fixed to the suction port 111, and the filter screen is provided with filter holes for filtering powder material 200.

[0053] Optionally, the air blowing pipe 20 is disposed on the side wall of the suction member 10 and located at the end away from the powder material 200, so as to prevent the powder material 200 from entering the air blowing pipe 20.

[0054] Optionally, the end of the air blowing pipe 20 away from the suction component 10 is set downward to prevent the powder material 200 from leaking out when suctioning powder.

[0055] Optionally, the inner diameter of the air blowing pipe 20 is D2, which is greater than or equal to 5 mm and less than or equal to 50 mm. This dimensional limitation allows for a suitable airflow velocity and pressure distribution under a given air source pressure. For example, the inner diameter D2 of the air blowing pipe 20 can be 5 mm, 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, 45 mm, or 50 mm. Of course, in other embodiments, the value of D2 is not limited to these values, and designers can make adaptive selections according to actual needs.

[0056] Optionally, the suction member 10 has a suction port 111 at one end, which is a nozzle 11. The nozzle 11 is cylindrical, meaning its cross-section is rectangular. The cylindrical nozzle 11 has a smooth inner wall, which reduces turbulence and ensures uniform airflow distribution within the pipe, improving suction efficiency. The cylindrical design also facilitates 360° rotation to adapt to suction needs at different angles. In other embodiments, the nozzle 11 can also be prismatic.

[0057] Example 2

[0058] This embodiment provides a suction gun mechanism 100. The specific structure of the suction gun mechanism 100 is basically the same as that of the suction gun mechanism 100 provided in Embodiment 1. The difference is that the specific shape of the gun head 11 is different.

[0059] like Figure 3 As shown, the gun head 11 provided in this embodiment is frustum-shaped, that is, the cross-section of the gun head 11 is trapezoidal. The frustum-shaped gun head 11 can enhance the compressive strength, reduce the risk of local deformation of the gun head 11, and extend the service life. Compared with the cylindrical gun head 11, the frustum-shaped gun head 11 is easier to insert into the powder material 200, which facilitates operation. In other embodiments, the gun head 11 can also be a frustum.

[0060] Example 3

[0061] This embodiment provides a suction gun mechanism 100. The specific structure of the suction gun mechanism 100 is basically the same as that of the suction gun mechanism 100 provided in Embodiment 1. The difference is that the specific shape of the gun head 11 is different.

[0062] like Figure 4 As shown, the nozzle 11 provided in this embodiment is conical, meaning that the cross-section of the nozzle 11 is conical. The conical nozzle 11 is easier to insert into the powder material 200 and can pierce the soft packaging bag 300 containing the powder material 200, ensuring convenient material suction. In other embodiments, the nozzle 11 can also be a pyramid.
