Description

Technical Field

[0001] This utility model relates to the field of new materials technology, specifically a dust-free feeding device. Background Technology

[0002] In many sectors of industrial production, such as chemicals, food processing, pharmaceuticals, and electronics, material loading is a crucial initial step in the production process. With continuous advancements in production technology and increasingly stringent requirements for the production environment and product quality, dust pollution during the loading process has become increasingly prominent, posing a significant challenge to improving production efficiency and ensuring product quality.

[0003] Traditional material feeding devices often fail to effectively control dust generation and dispersion during material feeding and conveying. Large amounts of dust not only severely pollute the working environment and endanger the health of operators, but also pose a series of safety hazards, such as dust explosions. Furthermore, dust mixed with materials affects product quality, leading to decreased product performance and increased defect rates. While some feeding devices employ simple dust control measures, such as dust covers, these only reduce dust dispersion to a certain extent and cannot effectively handle dust carried by the materials themselves or new dust generated during material flow. During material feeding, dust disperses freely, requiring frequent cleaning of the work area, increasing labor costs, and the deteriorating production environment is detrimental to the sustainable development of the enterprise. Utility Model Content

[0004] The purpose of this utility model is to provide a dust-free feeding device, which solves the technical problem that the dust carried by the material itself and the new dust generated by the material flow during the feeding process cannot be effectively treated, thereby ensuring that the feeding process is dust-free.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0029] Example 1:

[0030] Addressing the current problem of ineffective handling of dust inherent in the materials themselves and new dust generated during material flow during the feeding process, this utility model provides a preferred embodiment of a dust-free feeding device, for example... Figure 1-4 As shown: A dust-free feeding device includes a base 1, a controller 2 on the front of the base 1, a conveying assembly 3 on the top of the base 1, and a dustproof assembly 4 on the top of the base 1. The dustproof assembly 4 is located on one side of the conveying assembly 3. The conveying assembly 3 includes: a motor 311, fixedly installed on the front of the base 1; conveying shafts 312, equidistantly movably disposed between the inner walls of the base 1; and a dustproof cover 317, fixedly installed on the top of the base 1. Both ends of the conveying shafts 312 movably penetrate the inner wall of the base 1 and extend to the outer wall of the base 1, and are rotatably connected to the base 1 through bearings. A gear 313 is fixedly sleeved on one end of the outer wall of the conveying shaft 312. A transmission chain 314 is driven between the gears 313. The output end of the motor 311 is connected to one end of one of the conveying shafts 312. A conveying wheel 315 is fixedly sleeved on the outer wall of the conveying shaft 312. A conveyor belt 316 is driven between the conveying wheels 315.

[0031] Furthermore, in this embodiment, after the motor 311 is started, its output end drives the connected conveyor shaft 312 to rotate. Since the two ends of the conveyor shaft 312 are rotatably connected to the base 1 through bearings, the conveyor shaft 312 can rotate stably within the base 1. The gear 313 fixedly sleeved on one end of the outer wall of the conveyor shaft 312 rotates accordingly. Through the transmission action of the conveyor chain 314, the gears 313 on other conveyor shafts 312 are driven to rotate synchronously, so that all conveyor shafts 312 rotate together. The conveyor wheel 315 fixedly sleeved on the conveyor shaft 312 also rotates, thereby driving the conveyor belt 316 to circulate. The dust cover 317 can prevent dust from falling into the material during the conveying process.

[0032] Example 2:

[0033] Based on Embodiment 1, a preferred embodiment of the dust-free feeding device provided by this utility model is as follows: Figure 1-4 As shown: The dustproof component 4 includes: a feeding component 41, which is disposed on the top of the base 1; and a dust removal component 42, which is disposed inside the feeding component 41. The feeding component 41 includes: a fixing frame 411, which is symmetrically fixedly installed on the top of the base 1; a feeding box 412 is fixedly installed between the fixing frames 411; a discharge funnel 414 is connected to the bottom of the feeding box 412; a feed funnel 415 is connected to the top of the feeding box 412; a baffle 413 is fixedly installed on the outside of the fixing frame 411; a connection port is opened on the outside of the feeding box 412; and a guide plate 416 and an L-shaped guide plate 417 are symmetrically fixedly installed inside the feeding box 412. The L-shaped guide plate 417 is disposed directly below the guide plate 416. A second guide plate 418 is fixedly installed at the bottom of the material box 412. The second guide plate 418 is located directly below the L-shaped guide plate 417. Filter holes are equidistantly opened on the surface of the second guide plate 418. A vertical plate 419 is fixedly installed at the bottom of the second guide plate 418. A sliding rod 4111 is symmetrically fixedly installed on one side of the vertical plate 419. The sliding rod 4111 is fixedly connected to the inner wall of the feeding box 412. A receiving drawer 4112 is slidably connected to the outer wall of the sliding rod 4111. The receiving drawer 4112 is movably connected to the feeding box 412 through a connecting port. An outer plate 4113 is fixedly installed on the outer side of the receiving drawer 4112. A handle 4114 is fixedly installed on the outer side of the outer plate 4113. An exhaust vent is opened on the front of the feeding box 412.

[0034] Furthermore, in the embodiment, when the material falls onto the surface of the guide plate 418, the filter holes on the guide plate 418 allow fine dust in the material to pass through and fall into the receiving drawer 4112 below. The receiving drawer 4112 is slidably connected to the feeding box 412 via the slide rod 4111. The operator can pull the handle 4114 to pull the receiving drawer 4112 out from the connection port to clean the collected dust.

[0035] Example 3:

[0036] Based on Embodiments 1 and 2, a preferred embodiment of the dust-free feeding device provided by this utility model is, for example... Figure 1-4 As shown: The dust removal component 42 includes: a second motor 421, which is fixedly installed on the back of the feeding box 412; a filter plate 424, which is fixedly installed inside the exhaust port of the feeding box 412; and an exhaust frame 425, which is connected to the front of the feeding box 412. The output end of the second motor 421 is provided with a long shaft 422, the other end of which movably passes through the back of the outer wall of the feeding box 412, the back of the inner wall of the feeding box 412, and extends to the front of the inner wall of the feeding box 412. It is rotatably connected to the feeding box 412 through a bearing. The outer circumference of the long shaft 422 is equidistantly installed with unblocking blades 423, which are located between the first guide plate 416 and the L-shaped guide plate 417. The inside of the exhaust frame 425 is fixedly installed with a fine filter 426 and a dust removal mesh 427, which is located on the outside of the fine filter 426. An exhaust fan 428 is located on the outside of the exhaust frame 425.

[0037] Furthermore, in this embodiment, the motor 421 is started, and its output drives the long shaft 422 to rotate. The unblocking blades 423, which are equidistantly installed on the long shaft 422, rotate accordingly. The unblocking blades 423, which are set between the guide plate 416 and the L-shaped guide plate 417, can prevent the material from accumulating between the two guide plates and ensure the smooth falling of the material. The exhaust fan 428 is started, and a negative pressure is formed in the feeding box 412. The dust generated during the feeding process is sucked into the exhaust port on the front of the feeding box 412 under the action of negative pressure. The filter plate 424 performs preliminary filtration of the sucked dust, blocking larger dust particles. Then, the airflow continues to pass through the air outlet frame 425, the fine filter 426 and the dust removal mesh 427 to further finely filter the dust. Finally, the purified air is discharged from the equipment.

[0038] During operation, the operator starts the entire dust-free feeding device via controller 2. Controller 2 can control the start, stop, and setting of operating parameters for devices such as motor 311 and motor 421. After motor 311 starts, its output end drives the connected conveyor shaft 312 to rotate. Since both ends of the conveyor shaft 312 are rotatably connected to the base 1 through bearings, the conveyor shaft 312 can rotate stably within the base 1. The gear 313 fixedly sleeved on one end of the outer wall of the conveyor shaft 312 rotates accordingly. Through the transmission action of the conveyor chain 314, it drives the gears 313 on other conveyor shafts 312 to rotate synchronously, thereby causing all conveyor shafts 312 to rotate together. As the conveyor belt rotates, the conveyor wheel 315 fixedly mounted on the conveyor shaft 312 also rotates, thereby driving the conveyor belt 316 to circulate. The dust cover 317 can prevent dust from falling into the material during the conveying process. The material is fed into the feeding box 412 from the feeding funnel 415. The feeding funnel 415 guides the material into the feeding box 412, reducing spillage during material feeding. After entering the feeding box 412, the material first falls on the first guide plate 416. Under the action of gravity, it slides down the first guide plate 416, passes through the dust removal component 42, and falls onto the L-shaped guide plate 417. After being guided by the L-shaped guide plate 417, it finally falls onto the second guide plate 418. The second motor 421 starts. The output end of the fan drives the long shaft 422 to rotate, and the circumferentially spaced unblocking blades 423 on the long shaft 422 rotate accordingly. The unblocking blades 423, located between the guide plate 416 and the L-shaped guide plate 417, prevent material from accumulating between the two guide plates, ensuring smooth material flow. The exhaust fan 428 starts, creating a negative pressure inside the feeding box 412. Dust generated during the feeding process is drawn into the exhaust port on the front of the feeding box 412 under the action of negative pressure. The filter plate 424 performs preliminary filtration of the drawn-in dust, blocking larger dust particles. Then, the airflow continues to pass through the exhaust frame 425, the fine filter 426, and the dust collection mesh 427 for further filtration. The dust is finely filtered in the first step, and the purified air is discharged from the equipment. When the material falls onto the surface of the guide plate 418, the filter holes on the guide plate 418 allow the fine dust in the material to pass through and fall into the receiving drawer 4112 below. The receiving drawer 4112 is slidably connected to the feeding box 412 via the slide rod 4111. The operator can pull the receiving drawer 4112 out of the connection port by pulling the handle 4114 to clean the collected dust. After the material has been fed and the dust has been removed, the material falls from the discharge funnel 414 onto the running conveyor belt 316 below. The conveyor belt 316 then transports the material to the next process, completing the entire dust-free feeding process.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
