Description

Technical Field

[0001] This utility model relates to the field of feeding devices for dyeing vats, specifically a feeding device for dyeing vats. Background Technology

[0002] In the dyeing and finishing industry, the dyeing vat is the core equipment for dyeing fabrics, and the feeding device, as a key supporting component of the dyeing vat, directly affects the quality, efficiency, and stability of dyeing.

[0003] However, in current dyeing vat feeding devices, the mixing hopper is an important container for storing and dispensing dyes, auxiliaries, and other materials. But during long-term use, it has been observed that material arching is very likely to occur during storage and dispensing in the mixing hopper. Material arching prevents the material from flowing smoothly out of the hopper, causing problems such as uneven feeding and feeding interruption. This seriously affects the uniformity and consistency of dyeing, thereby reducing the quality of dyed products. For example, in the dyeing process of some high-end fabrics with high requirements for dyeing uniformity, material arching may cause defects such as color spots and color differences in the fabric, resulting in unqualified products and economic losses to enterprises. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a feeding device for dyeing vats, so as to solve the technical problem that the mixing hopper of the current dyeing vat feeding device is prone to material arching when storing and feeding dyes, auxiliaries and other materials, which leads to the inability of materials to flow out smoothly, uneven feeding, and feeding interruption, seriously affecting the uniformity and consistency of dyeing and reducing the quality of dyed products.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a feeding device for a dyeing vat, comprising a feeding device, the feeding device comprising a mixing hopper, two anti-arching mechanisms provided on the outer side of the mixing hopper, the anti-arching mechanism comprising a mounting frame, the outer surface of the mounting frame being provided with a slot, a plug being inserted into the slot, and a pneumatic vibrator being installed at the axis of the plug.

[0006] The vibrating end of the pneumatic vibrator is equipped with a flexible block, which is close to the mixing hopper. The mounting frame is screwed with fixing screws on both sides, and the two fixing screws are screwed to the insert block.

[0007] By adopting the above technical solution, two anti-arching mechanisms are installed on the outside of the mixing hopper. Their structure effectively solves the problem of material bridging. When material accumulates and blocks the flow, the anti-arching mechanisms act promptly, allowing the material to flow out smoothly, ensuring smooth feeding, and improving dyeing production efficiency and product quality.

[0008] Furthermore, the mounting bracket is provided with two sound insulation sheets at the top and bottom, and the sound insulation sheets are made of sound insulation cotton.

[0009] By adopting the above technical solution, sound-absorbing sheets made of sound-absorbing cotton are installed at the top and bottom of the mounting frame. When the pneumatic vibrator is working, it can effectively absorb and block the noise generated by vibration, reduce noise pollution, create a quiet and comfortable working environment for operators, and improve their work experience.

[0010] Furthermore, the top of the mixing hopper is provided with a hopper cover, and the front end of the hopper cover is rotatably connected to a feeding flip cover via a hinge.

[0011] By adopting the above technical solution, a hopper cover is installed at the top of the mixing hopper, and the front end is connected to the feeding flap via a hinge. This structure facilitates the addition of materials; materials can be added quickly by opening the feeding flap, while closing it prevents materials from spilling out and external impurities from entering, ensuring a clean production environment.

[0012] Furthermore, a motor is provided on the top of the hopper cover, and the output end of the motor passes through the hopper cover and is provided with stirring blades.

[0013] By adopting the above technical solution, a motor is installed at the top of the hopper lid, with the output end passing through the hopper lid and equipped with stirring blades. The motor drives the stirring blades to rotate, which can fully stir the materials in the hopper, so that the dyes and auxiliaries are mixed evenly, improving the dyeing effect and ensuring the stability of the dyed product quality.

[0014] Furthermore, the mixing hopper has an internal compartment, and the mixing hopper is configured in an inverted conical shape.

[0015] By adopting the above technical solution, the mixing hopper has an internal bin with an inverted cone shape. The inverted cone design facilitates the material to converge to the bottom under gravity, allowing for smooth material flow during feeding, reducing material residue, improving material utilization, and lowering production costs.

[0016] Furthermore, the inner side of the bin is provided with multiple baffles, and the multiple baffles are arranged in a ring array at equal intervals.

[0017] By adopting the above technical solution, multiple baffles arranged in a circular array at equal intervals are installed inside the hopper. During stirring, the baffles can change the flow direction of the material, enhance the stirring effect, and make the dye and auxiliaries mix more thoroughly and evenly, thereby further improving the dyeing quality.

[0018] Furthermore, the bottom of the mixing hopper is connected to a feeding pipe, and the outlet end of the feeding pipe extends into the dyeing vat.

[0019] By adopting the above technical solution, the bottom of the mixing hopper is connected to the feeding pipe, and the outlet extends into the dyeing vat. This structure ensures that the material can be accurately fed into the dyeing vat, avoids material spillage, guarantees the continuity and stability of the dyeing production process, and improves production efficiency.

[0020] Furthermore, the pneumatic vibrator contacts or maintains a small gap with the outer wall of the mixing hopper through the flexible block.

[0021] By adopting the above technical solution, the pneumatic vibrator contacts or maintains a small gap with the outer wall of the mixing hopper through a flexible block. The flexible block can effectively transmit vibration while avoiding damage to the mixing hopper, extending the service life of the equipment and reducing maintenance costs.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model, by setting up an anti-arching mechanism, wherein the mounting frame of the anti-arching mechanism is provided with a slot, and a plug block with a pneumatic vibrator is inserted into the slot. The vibrating end of the pneumatic vibrator contacts or maintains a small gap with the outer wall of the mixing hopper through a flexible block. The fixing screws on both sides of the mounting frame are screwed to the plug block. When the material in the mixing hopper arches, the pneumatic vibrator works to generate vibration, which is transmitted to the mixing hopper through the flexible block, thereby breaking the arching structure of the material and allowing the material to flow out of the hopper smoothly. This solves the problem that the mixing hopper of the current dyeing vat feeding device is prone to material arching when storing and feeding dyes, auxiliaries and other materials, which leads to the inability of the material to flow out smoothly, uneven feeding, feeding interruption, seriously affecting the uniformity and consistency of dyeing and reducing the quality of dyed products.

[0024] 2. This utility model provides sound insulation sheets at the top and bottom of the mounting frame. The sound insulation sheets are made of sound insulation cotton. When the pneumatic vibrator is working, the sound insulation cotton can effectively absorb and block the noise generated by the vibration, reducing the spread of noise to the surrounding environment. This solves the problem that the traditional feeding device anti-arching vibration device generates a lot of noise when it is working, which pollutes the working environment and affects the physical and mental health of the operators.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] A feeding device for a dyeing vat, such as Figure 1-4 As shown, it includes a feeding device 1, which includes a mixing hopper 101. Two anti-arching mechanisms 3 are provided on the outside of the mixing hopper 101. The anti-arching mechanism 3 includes a mounting frame 301. The outer surface of the mounting frame 301 is provided with a slot 304. A plug 305 is inserted into the slot 304, and a pneumatic vibrator 308 is installed at the axis of the plug 305.

[0032] The pneumatic vibrator 308 has a flexible block 306 at its vibrating end, which is close to the mixing hopper 101. The mounting frame 301 has fixing screws 302 threaded onto both sides, and the two fixing screws 302 are threaded onto the insert block 305. Two anti-arching mechanisms 3 are installed on the outside of the mixing hopper 101, a structure with significant advantages. During the dyeing process, materials easily arch within the mixing hopper 101, causing feeding difficulties. The mounting frame 301 in the anti-arching mechanism 3 provides overall support, and the slot 304 cooperates with the insert block 305 to facilitate the installation of the pneumatic vibrator 308. When materials arch, the pneumatic vibrator 308 operates, transmitting vibration to the mixing hopper 101 through the flexible block 306, breaking the arching structure and allowing the material to smoothly enter the dyeing vat 2 from the mixing hopper 101 via the feeding pipe 106, ensuring smooth feeding and improving dyeing production efficiency and product quality.

[0033] See Figure 3 , Figure 4The mounting bracket 301 has two sound-insulating sheets 303 at its top and bottom, and the material of the sound-insulating sheets 303 is sound-insulating cotton. This structure brings many benefits. During the operation of the feeding device for the dyeing vat, the pneumatic vibrator 308 in the anti-arching mechanism 3 will generate significant vibration and noise. The sound-insulating sheets 303, utilizing the properties of sound-insulating cotton, can effectively absorb and block the noise generated by these vibrations, reducing the transmission of noise to the surrounding environment. Whether in a small dyeing workshop or a large industrial dyeing plant, this can create a relatively quiet and comfortable working environment for operators, avoiding the damage to their physical and mental health caused by prolonged exposure to high noise levels, and improving work experience and efficiency.

[0034] See Figure 1 , Figure 4 The mixing hopper 101 has a lid 102 on top, and a feeding flap 103 is hinged to the front end of the lid 102. This ingenious and practical design allows for frequent addition of dyes, auxiliaries, and other materials to the mixing hopper 101 during the dyeing process. Operators can easily open the feeding flap 103 to quickly add materials into the hopper 105 inside the mixing hopper 101, greatly improving feeding efficiency. After feeding, the feeding flap 103 is closed, tightly sealing the lid 102 to effectively prevent spillage during subsequent mixing and feeding. It also prevents external dust and impurities from entering the mixing hopper 101, ensuring a clean production environment and material purity.

[0035] See Figure 1 , Figure 2 A motor 104 is installed on the top of the hopper lid 102. The output end of the motor 104 passes through the hopper lid 102 and is equipped with stirring blades. This structure is crucial for dyeing production. After dyes and auxiliaries are added to the hopper chamber 105 of the mixing hopper 101, the motor 104 is started, and its output end drives the stirring blades to rotate at high speed. The stirring blades thoroughly stir the materials in the hopper chamber 105, ensuring uniform mixing of dyes and auxiliaries and preventing localized over- or under-concentration. In subsequent feeding processes, the uniformly mixed materials enter the dyeing vat 2, ensuring consistent dyeing results, uniform fabric dyeing, and reducing defects such as color variations and uneven coloring. This improves the quality stability of dyed products and meets market demands for high-quality dyed products.

[0036] See Figure 3 , Figure 4The mixing hopper 101 has an internal compartment 105, which is an inverted cone shape. This design offers significant advantages. During the dyeing process, smooth material flow is crucial for ensuring production continuity and efficiency. The inverted cone design causes the bottom of the compartment 105 to gradually narrow, allowing material to naturally converge towards the bottom under gravity. During feeding, the material slides smoothly down the conical sidewall and is quickly and accurately fed into the dyeing vat 2 through the feeding pipe 106 connected to the bottom of the mixing hopper 101. This design effectively reduces material residue in the compartment 105, improves material utilization, lowers production costs, and avoids cross-contamination caused by material residue, thus ensuring the quality of the dyed products.

[0037] See Figure 4 The inner side of the hopper 105 is equipped with multiple baffles 107 arranged in a circular array at equal intervals. This structure significantly improves the mixing effect. When the motor 104 drives the stirring blades to agitate the material in the hopper 105, the baffles 107 interfere with the normal flow of the material. When the material flow encounters the baffles 107, its flow direction changes, forming complex eddies and turbulence. This change makes the relative motion between materials more intense, increasing the contact opportunities and mixing time between dyes and auxiliaries. Through this effect of the baffles 107, dyes and auxiliaries can be mixed more fully and uniformly within the hopper 105, providing a good material basis for the subsequent dyeing process, further improving dyeing quality and reducing the occurrence of dyeing defects.

[0038] See Figure 1 , Figure 4 The bottom of the mixing hopper 101 is connected to a feeding pipe 106, the outlet end of which extends into the dyeing vat 2. This structural design is both reasonable and practical. Accurately feeding the mixed materials into the dyeing vat 2 is a crucial step in dyeing production. The feeding pipe 106, serving as the channel for materials from the mixing hopper 101 to the dyeing vat 2, with its outlet end extending into the vat 2, ensures that the materials enter the vat 2 directly and accurately, avoiding waste and environmental pollution caused by spillage during feeding. Simultaneously, this design guarantees the continuity and stability of the dyeing production process, allowing materials to smoothly enter the dyeing vat 2 according to the predetermined flow, improving overall production efficiency and providing a strong guarantee for large-scale, high-efficiency dyeing production.

[0039] See Figure 4The pneumatic vibrator 308 contacts or maintains a small gap with the outer wall of the mixing hopper 101 through the flexible block 306. This structural design is ingenious. When the anti-arching mechanism 3 is working, the pneumatic vibrator 308 vibrates, and this vibration needs to be transmitted to the mixing hopper 101 through the flexible block 306 to break the material arching structure. The flexible block 306 has good elasticity and buffering performance. It can effectively transmit vibration while avoiding direct hard contact between the pneumatic vibrator 308 and the mixing hopper 101, thereby preventing damage to the mixing hopper 101 caused by the impact force of vibration, such as wear and deformation. This not only extends the service life of the mixing hopper 101 and reduces the maintenance cost of the equipment, but also ensures the long-term stable operation of the anti-arching mechanism 3, and improves the reliability and durability of the entire feeding device for the dyeing vat.

[0040] The implementation principle of this embodiment is as follows: First, before feeding, open the feeding flap 103 connected to the front end of the top cover 102 of the mixing hopper 101 by a hinge, and add dyes, auxiliaries and other materials into the hopper 105 opened inside the mixing hopper 101. Since the mixing hopper 101 is set with an inverted cone structure, this shape is conducive to the material gathering to the bottom under the action of gravity.

[0041] Next, the motor 104 installed on the top of the hopper cover 102 is started. The output end of the motor 104 drives the stirring blades that pass through the hopper cover 102 to rotate, stirring and mixing the material in the hopper 105. During the stirring process, multiple baffles 107 arranged in a ring array at equal intervals on the inner side of the hopper 105 will obstruct and interfere with the flow of the material, further enhancing the mixing effect of the material, so that the dye and auxiliaries can be fully and evenly mixed together.

[0042] When feeding is required, the material is fed into the dyeing vat 2 through the feeding pipe 106 connected to the bottom of the mixing hopper 101 under the action of gravity. During the feeding process, if the material in the mixing hopper 101 arches, causing the material to be unable to flow out smoothly, the anti-arching mechanism 3 is activated. In the anti-arching mechanism 3, a pneumatic vibrator 308 is installed at the center of the insert block 305 inserted into the slot 304 on the mounting frame 301. The pneumatic vibrator 308 generates vibration when it works. The vibration is transmitted to the outer wall of the mixing hopper 101 through the flexible block 306 at its vibrating end. The flexible block 306 contacts or maintains a small gap with the outer wall of the mixing hopper 101, which can effectively transmit the vibration and avoid damage to the mixing hopper 101 and destroy the arching structure of the material, so that the material can flow out of the mixing hopper 101 smoothly again, ensuring the uniformity and continuity of feeding.

[0043] Meanwhile, the sound insulation sheets 303 installed at the top and bottom of the mounting bracket 301 in the anti-arching mechanism 3 are made of sound insulation cotton. When the pneumatic vibrator 308 is working, the sound insulation cotton can effectively absorb and block the noise generated by the vibration, reduce the spread of noise to the surrounding environment, and provide a relatively quiet working environment for the operator. In addition, the fixing screws 302 screwed on both sides of the mounting bracket 301 are screwed to the insert block 305. This connection method facilitates the installation, disassembly and maintenance of the insert block 305 and the pneumatic vibrator 308.
