Description

Technical Field

[0001] This utility model relates to the field of powder spraying equipment technology, and in particular to an electric powder spraying machine that prevents powder buildup. Background Technology

[0002] Electric powder sprayers are a common work tool widely used in agricultural plant protection, sanitation and epidemic prevention, or industrial dust removal, for spraying powdered pesticides, medicines or other functional powders.

[0003] Existing electric powder coating machines typically include a hopper for holding the powder and a fan for generating airflow. However, many powder materials, especially pharmaceutical powders or fine chemical powders, have poor flowability and are prone to absorbing moisture and clumping due to environmental humidity.

[0004] When using a traditional powder coating machine, the powder in the hopper mainly relies on gravity to fall into the airflow channel of the blower through the narrow feed inlet. When dealing with the aforementioned powder with poor flowability, this passive feeding method is very likely to cause the powder to "bridge" or "rat hole" at the feed inlet, that is, the powder accumulates near the outlet and blocks the channel, preventing it from falling smoothly.

[0005] These accumulation and blockage problems cause powder spraying operations to be intermittent or even completely interrupted, severely impacting work efficiency. Operators are forced to frequently stop work to clear the feed inlet by tapping, shaking the equipment, or using tools, making operation extremely inconvenient. Furthermore, even if some powder falls, it may be in the form of unbroken clumps. These clumps are blown out directly by the airflow, causing uneven spraying, wasting material, and failing to achieve the desired coverage, resulting in poor overall work quality.

[0006] Therefore, this utility model proposes an electric powder spraying machine that prevents powder buildup, in order to overcome the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems in the existing electric powder spraying machine for preventing accumulation, such as powder bridging at the feed inlet causing blockage and poor material flow, and powder clumping due to insufficient dispersion leading to uneven spraying, this utility model aims to provide an electric powder spraying machine with an improved structure that can effectively solve the above problems.

[0008] This utility model provides an electric powder spraying machine for preventing accumulation, including the main body, and the feed hopper and the blower main unit installed inside the main body.

[0009] The anti-accumulation electric powder spraying machine also includes the turntable, the feed fan blades, the conical block, and the powdering fan blades.

[0010] The turntable is fixedly connected to the top of the blower host and rotatably disposed at the bottom outlet of the feed hopper. This arrangement allows the turntable to be directly driven to rotate by the blower host, providing active power for feeding.

[0011] Furthermore, the feed fan blades are fixedly connected to the turntable and located at the bottom outlet of the feed hopper. The feed fan blades rotate with the turntable, enabling them to actively break up arches and force the powder at the bottom of the feed hopper to be discharged.

[0012] Furthermore, the conical block is fixedly connected to the middle of the main fan unit, and the conical surface of the conical block provides a guiding and initial dispersion path for the falling powder.

[0013] Furthermore, the pollination fan blades are fixedly connected to the outside of the conical block. As the main fan rotates at high speed, the pollination fan blades forcefully impact and centrifugally disperse the powder sliding off the conical block.

[0014] In this way, the main fan unit integrates the power of the feed fan blades and the pollination fan blades into one unit, realizing dual structural control of feed anti-blocking and discharge dispersion by a single power source.

[0015] Preferably, the anti-accumulation electric powder spraying machine further includes the feeding assembly, which includes the anti-overflow shell. The anti-overflow shell is fixedly connected to the bottom outlet of the feeding hopper and covers the outer periphery of the turntable and the feeding fan blades. This structure is used to prevent powder that may be generated when the feeding fan blades rotate from splashing in all directions, ensuring that the powder enters the next stage in a controlled manner.

[0016] Preferably, the anti-accumulation electric powder spraying machine further includes the powder discharge assembly, which includes the upper fan housing and the lower fan housing. The lower fan housing is installed and fixed inside the main body and the main fan is installed at its center. The upper fan housing and the lower fan housing are fixedly connected, and the two together form a cavity that accommodates the conical block and the powdering fan blades. This cavity not only provides a limited space for the powder to be dispersed, but also constitutes a channel for airflow.

[0017] Preferably, the anti-accumulation electric powder sprayer also includes the corrugated pipe, one end of which is threadedly connected to the side wall of the cavity formed by the upper and lower housings of the blower. The corrugated pipe serves as a flexible output channel, making it easy for the operator to adjust the spraying direction and adapt to different working environments.

[0018] Preferably, the anti-accumulation electric powder spraying machine further includes the connecting sleeve, which is fixedly connected to the end of the corrugated pipe away from the powder outlet assembly. The connecting sleeve is used to gather airflow and dust to form a directional and concentrated nozzle.

[0019] Preferably, the anti-accumulation electric powder spraying machine further includes the upper shell, which is detachably connected to the top of the main body to block the inlet of the feed hopper. This structure facilitates the user to fill the feed hopper with powder and protects the interior of the main body from contamination by debris.

[0020] Preferably, the anti-accumulation electric powder spraying machine further includes the bottom shell, which is fixedly connected to the bottom of the main body. The battery pack that supplies power to the main fan is installed inside the bottom shell, and the bottom shell provides a stable installation space and physical protection for the battery pack.

[0021] Preferably, in the above-described embodiment where the battery pack is provided, the battery cover is installed on the top of the battery pack, and the battery cover is used to press and fix the battery pack and protect the electrodes.

[0022] Preferably, in the above-described embodiment with the bottom shell, the bottom shell is fixedly connected to the screw sleeves on all four sides. The screw sleeves provide a more reliable connection base for the mounting screws and enhance the connection strength between the bottom shell and the main body. Furthermore, a heat dissipation vent is provided at the center of the bottom shell to allow air convection between the fan host and the battery pack during operation, thereby dissipating heat in a timely manner.

[0023] This utility model has the following beneficial effects: 1. This utility model, by setting up feeding fan blades and pollination fan blades driven by the same blower host, enables the active rotation of the feeding fan blades to break the blockage of powder at the feed inlet, while the high-speed rotation of the pollination fan blades powerfully disperses the powder, thus solving the problems of powder blockage at the feed inlet and agglomeration at the discharge outlet leading to uneven spraying in the prior art, achieving the dual technical effects of smooth feeding and uniform powder spraying.

[0024] 2. This utility model achieves active forced feeding by setting a feeding fan blade driven by a motor at the bottom outlet of the feeding hopper. This solves the problem of powder bridging and blockage caused by relying solely on gravity feeding in the existing technology, and achieves the technical effect of preventing accumulation at the feeding port and improving feeding efficiency.

[0025] 3. This utility model, by setting high-speed rotating pollination fan blades and conical blocks, and forming a fan cavity on its outer periphery, allows the falling powder to be forcefully dispersed and immediately blown away by the airflow, solving the problem of powder easily clumping and clogging the nozzle in the prior art, and achieving the technical effect of uniform spraying and preventing secondary accumulation at the powder outlet.

[0026] 4. This utility model integrates the feeding anti-blocking function and the discharging function into one by adopting an integrated design in which a single fan host simultaneously drives the feeding fan blade and the pollination fan blade. This solves the problem that multiple power sources or complex transmission mechanisms are required to achieve similar functions in the prior art, and achieves the technical effects of simplified structure, reduced manufacturing cost and improved equipment integration.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] Example: Please refer to Figures 1 to 4 This utility model provides an electric powder spraying machine that prevents powder accumulation, which aims to solve the problems of powder clogging at the feed inlet and powder agglomeration at the outlet, resulting in uneven spraying.

[0031] like Figure 1As shown, the anti-accumulation electric powder spraying machine includes a main body 2, inside which a feeding assembly 5 and a powder discharging assembly 6 are installed. An upper shell 1 is closably connected to the top of the main body 2, a bottom shell 7 is fixedly connected to the bottom of the main body 2, a corrugated pipe 3 is fixedly connected to one side of the main body 2, and a connecting sleeve 4 is fixedly connected to the end of the corrugated pipe 3 away from the main body 2. A battery pack 10 is installed inside the bottom shell 7, and a battery cover 9 is installed on the top of the battery pack 10. Screw sleeves 11 are fixedly connected to all four sides of the bottom shell 7, and a heat dissipation vent 8 is provided at the center of the bottom shell 7. Figure 2 and Figure 3 As shown, the powder discharge assembly 6 includes an upper fan housing 601 and a lower fan housing 602. The main fan 603 is installed at the center of the lower fan housing 602, and the upper fan housing 601 and the lower fan housing 602 are fixedly connected. The feeding assembly 5 includes a feeding hopper 501, and an anti-overflow shell 504 is fixedly connected to the bottom outlet of the feeding hopper 501. The core linkage of this structure is reflected in the following: a turntable 503 is fixedly connected to the top of the blower host 603. The turntable 503 is rotatably set at the bottom outlet of the feed hopper 501 and located inside the anti-overflow shell 504. The feed fan blade 502 is fixedly connected to the turntable 503. At the same time, the conical block 604 is fixedly connected to the middle of the blower host 603, and the pollination fan blade 605 is fixedly connected to the outside of the conical block 604. The conical block 604 and the pollination fan blade 605 are both accommodated in the cavity formed by the upper shell 601 and the lower shell 602 of the blower.

[0032] To solve the above technical problems, the main fan 603 simultaneously drives the feeding component 5 at the feeding end and the powder discharge component 6 at the powder discharge end, forming a linked structure for preventing accumulation and uniform spraying.

[0033] Please refer to the following carefully. Figure 2 and Figure 3 The structure will be described in detail below: The core of the feeding component 5 lies in its active feeding structure, as shown in the reference... Figure 2 The feed hopper 501 is installed and fixed on the upper part of the main body 2. The top of the blower host 603 is fixedly connected to the turntable 503. The turntable 503 is rotatably set at the bottom outlet position of the feed hopper 501. The feed fan blade 502 is fixedly connected to the upper surface of the turntable 503. This structure allows the feed fan blade 502 to rotate synchronously when the blower host 603 is started, forcibly agitating the powder in the feed hopper 501 and conveying it downward, thereby actively breaking the bridging that may be formed at the outlet of the powder and ensuring the smooth feeding process. To prevent the powder from overflowing, the anti-overflow shell 504 is fixedly connected to the bottom outlet of the feed hopper 501 and covers the outer periphery of the turntable 503 and the feed fan blade 502.

[0034] Meanwhile, the core of powder dispensing component 6 lies in its high-speed dispersing and airflow conveying structure, referring to... Figure 3The conical block 604 is fixedly connected to the middle of the blower host 603. The conical block 604 has a shape with a small diameter at the top and a large diameter at the bottom. The pollination fan blade 605 is fixedly connected to the outside of the conical block 604. When the blower host 603 drives the conical block 604 and the pollination fan blade 605 to rotate at high speed, the powder falling from the feeding component 5 first contacts the conical surface of the conical block 604 and slides down to the pollination fan blade 605. Then, it is strongly impacted and dispersed into uniform dust by the high-speed rotating pollination fan blade 605. The blower host 603, as the power source, will immediately blow these dusts away when it is working, realizing the synchronization of dispersion and conveying, and avoiding secondary accumulation of dust.

[0035] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, please refer to Figure 2 In order to achieve the complete construction of the feeding assembly 5 and prevent the powder from overflowing, the feeding assembly 5 also includes an anti-overflow shell 504, which is fixedly connected to the bottom outlet of the feeding hopper 501 and covers the outer periphery of the turntable 503 and the feeding fan blade 502.

[0036] As a preferred embodiment, please refer to Figure 3 To achieve the complete construction of the dust discharge component 6 and to define the space for dust dispersion and blowing, the dust discharge component 6 also includes an upper fan housing 601 and a lower fan housing 602. The lower fan housing 602 is installed and fixed inside the main body 2 and the main fan 603 is installed at its center. The upper fan housing 601 and the lower fan housing 602 are fixedly connected, and the two together form a cavity that accommodates the conical block 604 and the pollination fan blades 605.

[0037] As a preferred embodiment, please refer to Figure 1 To guide the dust output path, it also includes a bellows 3, one end of which is threadedly connected to the side wall of the cavity formed by the upper casing 601 and the lower casing 602 of the fan.

[0038] As a preferred embodiment, please refer to Figure 1 To provide a terminal outlet for spraying, it also includes a connecting sleeve 4, which is fixedly connected to the end of the bellows 3 away from the powder outlet assembly 6.

[0039] As a preferred embodiment, please refer to Figure 1 In order to facilitate the filling of powder into the feed hopper 501 and to seal the interior of the main body 2, it also includes an upper shell 1, which is detachably connected to the top of the main body 2 and is used to block the inlet of the feed hopper 501.

[0040] As a preferred embodiment, please refer to Figure 1 and Figure 4It provides the mounting base and power supply for the entire device, and also includes a bottom shell 7, which is fixedly connected to the bottom of the main body 2; the bottom shell 7 houses a battery pack 10 that powers the main fan 603.

[0041] In the embodiment described above where the battery pack 10 is installed, please refer to... Figure 4 To secure and protect the battery pack 10, a battery cover 9 is installed on the top of the battery pack 10.

[0042] In the above-described embodiment with the bottom shell 7, please refer to... Figure 4 To ensure a secure connection between the bottom shell 7 and the main body 2, threaded sleeves 11 are fixedly connected around the bottom shell 7. Meanwhile, to ensure the stability of the fan host 603 and the battery pack 10 during operation, a heat dissipation vent 8 is provided at the center of the bottom shell 7.

[0043] The working principle of this anti-accumulation electric powder spraying machine is as follows: When powder spraying is required, the operator turns on the switch, and the battery pack 10 located inside the bottom shell 7 starts to supply power. The top of the battery pack 10 is covered with a battery cover plate 9, and the power drives the blower host 603 to rotate at high speed. The rotation of the blower host 603 will simultaneously drive the movement of two core components: the first is the turntable 503 and the feed fan blade 502 fixed on its top, and the second is the conical block 604 and the pollination fan blade 605 fixed in its middle.

[0044] During the feeding stage, the powder is poured into the feed hopper 501 through the open upper shell 1. At this time, the rotating feed fan blades 502 actively stir and forcefully press down on the powder at the bottom outlet of the feed hopper 501, effectively breaking the bridging blockage that is easily formed by the accumulation of powder, so that the powder can fall smoothly into the powder discharge component 6 below. The anti-overflow shell 504 located at the bottom can prevent the powder from overflowing.

[0045] During the powder dispensing stage, the smoothly falling powder first contacts the surface of the high-speed rotating conical block 604 and slides down and disperses along its conical outer wall. It is then powerfully impacted and dispersed by the pollination fan blades 605, which are fixed to the outside of the conical block 604 and rotate at high speed simultaneously, crushing any powder that may clump into uniform dust. At the same time, the blower host 603 itself operates as a blower, generating a strong airflow in the cavity formed by the blower upper shell 601 and the blower lower shell 602. This airflow carries the dust that has been instantly dispersed by the pollination fan blades 605 and sprays it out at high speed through the corrugated pipe 3 and the connecting sleeve 4, thus completing the anti-clogging feeding and uniform powder spraying operation. The entire device uses the main body 2 as the mounting frame, the screw sleeve 11 on the bottom shell 7 for secure connection, and the heat dissipation port 8 in the center of the bottom shell 7 to provide a heat dissipation channel for the blower host 603 and the battery pack 10.

[0046] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
