Description

Technical Field

[0001] This utility model relates to the field of powder coating technology, and in particular to a powder cabinet hook protection device with a powder baffle structure. Background Technology

[0002] In industrial fields such as powder coating and electrostatic adsorption, the conductivity of the coating rack directly affects the powder application rate and coating efficiency. Existing powder coating equipment faces the following core problems during use:

[0003] Powder buildup on the main hook causes conductivity failure:

[0004] As the conductive core of the hanger, the main hook is easily covered by powder during cyclic operation. For example, in traditional powder cabinets, the surface of the main hook hanger is completely covered by powder after every 4-5 cycles, resulting in loss of conductivity. This requires frequent shutdowns for cleaning or replacement of the hanger, which seriously affects production efficiency and increases maintenance costs.

[0005] Therefore, we propose a powder cabinet hook protection device with a powder baffle structure. Utility Model Content

[0006] The purpose of this utility model is to provide a powder cabinet hook protection device with a powder baffle structure, thereby solving or at least alleviating one or more of the above-mentioned problems and other problems existing in the prior art.

[0028] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0029] Please refer to Figures 1 to 5 As shown, an embodiment of this utility model provides a powder cabinet hook protection device with a powder baffle structure, including a slot 101 opened at the top of the powder cabinet body 1. The slot 101 is located directly below the chain guide rail 6, and a powder baffle mechanism 2 is installed at the bottom of the slot 101 to cover the main hook 3 at the bottom of the chain guide rail 6. The slot 101 at the top of the powder cabinet body 1 provides a moving channel for the chain guide rail 6 and the main hook 3 and auxiliary hook 4 of the hanging device.

[0030] The powder blocking mechanism 2 is installed at the bottom of the slot 101. It physically blocks the powder from being sprayed directly onto the surface of the main hook 3, thereby reducing powder accumulation on the main hook 3.

[0031] Furthermore, the powder blocking mechanism 2 includes two powder blocking plates 201. The two powder blocking plates 201 are fixedly installed on the bottom sides of the slot 101 respectively. An upper channel 206 for the main hook 3 to pass through is formed between the two powder blocking plates 201. A baffle 204 is fixedly connected to the bottom of the powder blocking plate 201. A lower channel 207 for the auxiliary hook 4 to pass through is formed between the two baffles 204. The width of the upper channel 206 is greater than the width of the lower channel 207.

[0032] Two powder baffles 201 are symmetrically distributed on both sides of the bottom of the slot 101, and the baffle strip 204 further narrows the channel size, forming a spatial structure that is wider at the top and narrower at the bottom.

[0033] The width of the upper channel 206 is adapted to allow passage at the connection point between the main hook 3 and the auxiliary hook 4, thus confining the main hook 3 within the upper channel 206 during movement. Only the narrower portion of the lower end of the auxiliary hook 4 can pass through the lower channel 207 to enter the powder chamber. The lower channel 207 only allows the auxiliary hook 4 with a wire diameter of φ3 to pass through, forming a strict physical obstruction to the main hook 3. The auxiliary hook 4 enters the powder chamber through the lower channel 207 to receive the powder sprayed from the spray guns 5 on both sides of the powder chamber body 1, while the main hook 3 cannot enter the powder accumulation area due to the obstruction of the baffle 204. This upper-wide and lower-narrow channel design achieves graded obstruction of the main hook 3.

[0034] Furthermore, the two powder baffles 201 are symmetrically distributed with the center line of the chain guide rail 6 as the axis of symmetry.

[0035] The symmetrically distributed dust baffles 201 ensure uniform dust blocking force on both sides of the chain guide rail 6, preventing dust accumulation on the main hook 3 due to insufficient dust blocking on one side. Moreover, the symmetrical structure ensures balanced force on the hanger during movement, preventing the secondary hook 4 from getting stuck or the main hook 3 from accidentally entering the dust accumulation area due to tilting.

[0036] In this embodiment, guide strips 205 are formed at both ends of the baffle 204.

[0037] The guide bar 205 is used to guide the auxiliary hook 4 to pass smoothly through the lower channel 207, reduce the frictional resistance when the hanger moves, and prevent the auxiliary hook 4 from deforming or getting stuck due to hard collision with the stop bar 204, thus ensuring the continuity of the production process.

[0038] In this embodiment, the powder baffle 201 is a metal plate, and the baffle strip 204 is a metal strip.

[0039] The metal material has good electrical conductivity, which can enhance the electrostatic shielding effect of the Faraday effect and effectively block the electrostatic adsorption path between the main hook 3 and the powder.

[0040] Made of high-strength metal, it is resistant to powder impact and abrasion, making it suitable for long-term operation in high-dust environments such as powder cabinets.

[0041] In this embodiment, the powder baffle 201 and the baffle strip 204 may be made of materials including but not limited to stainless steel and aluminum alloy.

[0042] Furthermore, the thickness of the powder baffle 201 is 1mm to 3mm. This thickness range of 1mm to 3mm balances structural strength and electrostatic shielding efficiency. If the thickness is too thin, it is prone to deformation and cannot effectively block powder; if the thickness is too thick, it may increase the shielding area and affect the smooth passage of the secondary hook 4.

[0043] In this embodiment, the top of the powder baffle 201 is provided with a flange 202, and the flange 202 is provided with a plurality of mounting holes 203. The flange 202 is fixedly installed on the inner top of the powder cabinet body 1 by bolts.

[0044] The flange 202 is fixedly connected to the top of the powder cabinet 1 through the mounting hole 203 and bolts, ensuring that the powder baffle 201 is installed firmly and avoiding positional displacement due to vibration or powder impact.

[0045] The modular design facilitates disassembly and maintenance, allowing for quick cleaning or replacement of the dust baffle plate 201.

[0046] Working principle:

[0047] When the main hook 3 and the auxiliary hook 4 move along the chain guide 6 through the slot 101, the main hook 3 is blocked by the powder baffle 201 in the upper channel 206, while the auxiliary hook 4 enters the powder cabinet through the lower channel 207. Inside the powder cabinet 1, the auxiliary hook 4 is sprayed by the spray gun 5, and the charged powder is attracted to the workpiece due to electrostatic attraction. The metal structure of the powder baffle 201 and the baffle 204 forms an electrostatic shield. The presence of the lower channel 207 exacerbates the electric field distortion, weakens the electrostatic attraction force on the surface of the main hook 3, and prolongs the service life of the main hook 3.

[0048] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the present invention's conception through the foregoing teachings or related technical or knowledge.
