Description

Technical Field

[0001] This utility model belongs to the field of dye production technology, and in particular relates to a feeding device for dye production. Background Technology

[0002] In dye production, the feeding device is a crucial link connecting raw material storage and production reaction equipment (such as reaction kettles, dissolving tanks, mixing tanks, etc.). Its main function is to accurately, safely, efficiently, and controllably add various raw materials (solid, powder, liquid) into designated production containers. Because dye production involves raw materials in various physical forms (solid blocks, powders, granules, liquids, slurries, etc.), and these raw materials often possess characteristics such as flammability, explosiveness, toxicity, harmfulness, high dust levels, hygroscopicity, or easy oxidation, the design and selection of the feeding device are of paramount importance. Dust is easily generated during the powder feeding stage in dye production (especially during the unpacking of ton bags and small bags, and vacuum loading and unloading). Due to inadequate sealing in the feeding devices used in related dye production technologies, dust escape is a common problem. Summary of the Invention

[0003] In view of this, the present invention aims to at least partially solve one of the related technical problems.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A feeding device for dye production includes a conveying mechanism, a feeding guide structure, a cutting structure, a fixed base, a feeding hood, a bag cleaning vibration mechanism, two laminar flow air curtain mechanisms, and two suction mechanisms.

[0006] One end of the material conveying guide structure is directly opposite the conveying mechanism, and the other end of the material conveying guide structure is connected to the fixed base. The material conveying guide structure is inclined, and the cutter structure is disposed inside the material conveying guide structure.

[0007] The fixed base has a hollow structure inside, and the bag cleaning vibration mechanism is set inside the hollow structure. The top of the bag cleaning vibration mechanism is directly opposite the bottom of the material conveying guide structure.

[0008] The feeding hood is detachably connected to the upper end face of the fixed base. The feeding hood is used to cover the top of the bag cleaning vibration mechanism. The feeding hood has a feeding port on its side, and the feeding port is directly opposite the bottom of the material conveying guide structure.

[0009] Two laminar flow air curtain mechanisms are symmetrically arranged on the top of the feeding hood, and two suction mechanisms are symmetrically arranged on the side of the feeding hood.

[0010] Furthermore, the material conveying guide structure includes a material conveying trough, two limiting plates and multiple guide rollers. The material conveying trough is inclined, and the two limiting plates are symmetrically arranged on both sides of the material conveying trough. An installation plate is provided at the bottom of the material conveying trough, and the installation plate is connected to the fixed base. The multiple guide rollers are evenly distributed on the material conveying trough, and the cutting structure is arranged on the material conveying trough.

[0011] Furthermore, the cutting structure includes multiple strip cutters, which are evenly arranged side by side in the feeding trough, and the strip cutters are used to cut open the dye bag.

[0012] Furthermore, the hollow structure is a rectangular slot, and the bag cleaning vibration mechanism is disposed within the rectangular slot.

[0013] Furthermore, the bag cleaning vibration mechanism includes two vibrating plates, two vibration motors, two fixed plates, four spring-loaded mechanisms, and multiple screen bars. The two vibrating plates are symmetrically arranged in the rectangular slot, and the multiple screen bars are evenly distributed between the two vibrating plates. The front and rear ends of each screen bar are fixedly connected to one of the vibrating plates. A fixed plate is correspondingly arranged directly below each vibrating plate. The fixed plate is welded to the fixed base. Each fixed plate is connected to the vibrating plate through two spring-loaded mechanisms. A vibration motor is correspondingly arranged on the lower end face of each vibrating plate.

[0014] Furthermore, the spring-loaded mechanism includes a guide rod, a limiting nut, a baffle, and two vibration springs. The top of the guide rod is threadedly connected to the vibration plate, and the guide rod is slidably engaged with the fixed plate. The limiting nut and the baffle are both located at the bottom of the guide rod. The two vibration springs are symmetrically arranged on the guide rod, with one vibration spring located between the vibration plate and the fixed plate, and the other vibration spring located below the fixed plate. The baffle is used to limit the vibration spring, and the limiting nut is used to limit the baffle.

[0015] Furthermore, the laminar flow air curtain mechanism includes a first centrifugal fan and multiple air guide chambers. The side end of the top of the feeding hood is provided with an installation slot, and the multiple air guide chambers are arranged in an inclined manner in the installation slot. The first centrifugal fan is connected to a flange connecting sleeve through a pipe. The flange connecting sleeve is equipped with a rectangular connecting plate that can be adapted to the installation slot. The rectangular connecting plate is fixedly connected to the installation slot by bolts.

[0016] Furthermore, the material suction mechanism includes a second centrifugal fan, a pipe interface, and a dust suction pipe. The second centrifugal fan is connected to the pipe interface through the dust suction pipe, and the pipe interface is located on the side of the material feeding hood.

[0017] Compared with existing technologies, the feeding device for dye production described in this utility model has the following advantages:

[0018] 1. The laminar flow air curtain mechanism effectively blocks the dust diffusion path. This mechanism creates a highly efficient and dynamic isolation layer between the material falling area and the external environment by constructing a uniform, vertical airflow barrier at the top of the feeding hood. As the dye bag falls after being cut by the cutter, the laminar flow air curtain continuously delivers airflow with stable, low-turbulence characteristics, exhibiting strictly parallel airflow lines with no significant lateral disturbance. This directional airflow has a dual inhibitory effect on dust particles: firstly, by directly pressing the lightweight dust particles that have just detached from the packaging bag into the negative pressure area inside the feeding hood, it effectively blocks their natural upward path; secondly, it creates a localized positive pressure environment above the inlet, significantly suppressing the promoting effect of external air turbulence on dust diffusion.

[0019] 2. When handling organic dyes that are prone to generating static electricity, directional airflow can also help dissipate the triboelectric charge on the material, reducing the risk of dust explosion. The entire protective process is completed silently, ensuring a comfortable working environment while allowing operators to intuitively perceive the protective status through the visual airflow design, greatly improving the feasibility of production safety management.

[0020] 3. The bag-cleaning vibration mechanism, based on the principle of vibration transmission, enables deep cleaning of pre-cut dye bags. When the dye-filled logistics bag slides down the conveying guide structure onto the vibrating plate surface, the support surface composed of multiple sets of screen bars forms a uniformly distributed vibration grid, causing the vibration force to diffuse layer by layer from the bottom of the bag upwards in a wave-like form. This design effectively avoids the localized impact effect produced by traditional mechanical beating methods. Especially for reactive dyes that are prone to moisture absorption and clumping or organic pigments with electrostatic adsorption characteristics, the vibration energy can penetrate the material accumulation layer, effectively breaking down the hidden caking structure that is difficult to detect with the naked eye, thereby achieving a near-complete material release effect.

[0032] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] A feeding device for dye production, such as Figure 1 As shown, it includes a conveying mechanism 100, a material guiding structure 200, a cutting structure, a fixed base 410, a feeding hood 420, a bag cleaning vibration mechanism, two laminar flow air curtain mechanisms, and two suction mechanisms; one end of the material guiding structure 200 is directly opposite to the conveying mechanism 100, and the other end of the material guiding structure 200 is connected to the fixed base 410. The material guiding structure 200 is inclined, and the cutting structure is set inside the material guiding structure 200.

[0034] like Figure 3 As shown, the fixed base 410 has a hollow structure inside, and the bag cleaning vibration mechanism is set inside the hollow structure. The top of the bag cleaning vibration mechanism is directly opposite the bottom of the material conveying guide structure 200. The hollow structure is a rectangular slot, and the bag cleaning vibration mechanism is set inside the rectangular slot. The bag cleaning vibration mechanism includes two vibrating plates 310, two vibrating motors 340, two fixed plates 430, four spring pressing mechanisms 330, and multiple screen bars 320. The two vibrating plates 310 are symmetrically arranged in the rectangular slot, and the multiple screen bars 320 are evenly distributed between the two vibrating plates 310. The front and rear ends of the screen bars 320 are fixed to one vibrating plate 310 respectively. A fixed plate 430 is set directly below each vibrating plate 310. The fixed plate 430 is welded to the fixed base 410. Each fixed plate 430 is connected to the vibrating plate 310 through two spring pressing mechanisms 330. A vibrating motor 340 is set on the lower end face of each vibrating plate 310.

[0035] The bag-cleaning vibration mechanism, based on the principle of vibration transmission, enables deep cleaning of pre-cut dye bags. When the dye-filled logistics bag slides down the conveying guide structure 200 onto the surface of the vibrating plate 310, the supporting surface, composed of multiple sets of screen bars 320, forms a uniformly distributed vibration grid, causing the vibration force to diffuse upwards in a wave-like manner from the bottom of the bag. This design effectively avoids the localized impact effect of traditional mechanical beating methods. Especially for reactive dyes that easily absorb moisture and clump, or organic pigments with electrostatic adsorption properties, the vibration energy can penetrate the material accumulation layer, effectively breaking down hidden caking structures that are difficult to detect with the naked eye, thereby achieving a near-complete material release effect.

[0036] The spring-loaded mechanism 330 includes a guide rod, a limiting nut, a baffle plate, and two vibration springs. The top of the guide rod is threadedly connected to the vibration plate 310, and the guide rod is slidably engaged with the fixed plate 430.

One vibration spring is located between the vibration plate 310 and the fixed plate 430, and the other vibration spring is located below the fixed plate 430. The baffle plate is used to limit the vibration springs, and the limiting nut is used to limit the baffle plate.

[0037] The feeding hood 420 is connected to the upper end face of the fixed base 410 by screws. The feeding hood 420 is used to cover the top of the bag cleaning vibration mechanism. The feeding hood 420 has a feeding port on its side, which is directly opposite the bottom of the material conveying guide structure 200.

[0038] Two laminar flow air curtain mechanisms are symmetrically arranged on the top of the feeding hood 420, and two suction mechanisms are symmetrically arranged on the sides of the feeding hood 420. The laminar flow air curtain mechanism includes a first centrifugal fan and multiple air guide chambers. An installation slot 500 is provided at the side end of the top of the feeding hood 420, and the multiple air guide chambers are arranged at an angle within the installation slot 500. The first centrifugal fan is connected to a flange connecting sleeve via a pipe. The flange connecting sleeve is equipped with a rectangular connecting plate that fits the installation slot 500, and the rectangular connecting plate is fixedly connected to the installation slot 500 by bolts. The suction mechanism includes a second centrifugal fan, a pipe interface 600, and a dust suction pipe. The second centrifugal fan is connected to the pipe interface 600 via a dust suction pipe, and the pipe interface 600 is located on the side of the feeding hood 420.

[0039] The laminar flow air curtain mechanism effectively blocks the dust diffusion path. This mechanism creates a uniform, vertical airflow barrier at the top of the feeding hood 420, forming a highly efficient and dynamic isolation layer between the material falling area and the external environment. As the dye bag falls after being cut by the cutter, the laminar flow air curtain continuously delivers an airflow with stable, low-turbulence characteristics, exhibiting strictly parallel airflow lines with no significant lateral disturbance. This directional airflow has a dual inhibitory effect on dust particles: firstly, by directly pressing the lightweight dust particles that have just detached from the packaging bag into the negative pressure area inside the feeding hood 420, it effectively blocks their natural upward path; secondly, by creating a localized positive pressure environment above the inlet, it significantly suppresses the promoting effect of external air turbulence on dust diffusion.

[0040] When handling organic dyes that are prone to static electricity, directional airflow can also help dissipate the triboelectric charge on the material, reducing the risk of dust explosion. The entire protective process is completed silently, ensuring a comfortable working environment while allowing operators to intuitively perceive the protective status through the visual airflow design, greatly improving the feasibility of production safety management.

The material feeding trough 210 is inclined, and the two limiting plates 220 are symmetrically arranged on both sides of the material feeding trough 210. A mounting plate is provided at the bottom of the material feeding trough 210, and the mounting plate is connected to the fixed base 410.
