Description

Technical Field

[0001] This utility model belongs to the field of wool fulling technology, and in particular relates to a chemical reagent addition device for fulling coarse wool. Background Technology

[0002] In the processing of coarse wool, fulling is necessary to achieve a tight structure, soft hand feel, and good warmth retention in wool fabrics. Fulling is a key process that uses the combined effects of mechanical force, chemical reagents, and temperature and humidity conditions to cause the wool fibers to become entangled and felted, thereby achieving dimensional stability and performance improvement in the fabric. The fulling machine is the core equipment for completing this process.

[0003] Existing traditional wool fulling machines generally employ two methods for adding fulling agents: direct injection and atomized injection. Atomized injection involves injecting atomized agents into the outer roller, which then adheres to the wool fabric through holes in the inner roller. However, this method relies entirely on the atomized flowability of the agent. In actual fulling processes, due to the high-speed rotation of the inner roller, the atomized agent in the outer roller cannot accurately and evenly enter the inner roller through the holes and act on the wool fabric, easily leading to uneven distribution of the agent and affecting the fulling quality. Furthermore, some agent may remain on the inner wall of the outer roller or be discharged directly with the waste liquid, resulting in agent waste and increased production costs.

[0004] Therefore, it is essential to invent a device for adding chemical reagents to wool fulling. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a chemical reagent addition device for wool fulling, including a fulling machine housing, an outer roller, a back plate, an inner roller, a fulling addition mechanism, a drain pipe, a water injection pipe, a driven disc, a belt, a drive disc, and a drive component. The outer roller and the back plate are fixedly installed inside the fulling machine housing. The inner roller is rotatably installed inside the fulling machine housing and the outer roller. The fulling addition mechanism is installed on the fulling machine housing and the inner roller. The rotating shaft of the inner roller rotatably passes through the outer roller and is fixedly connected to the driven disc. The driven disc is connected to the drive disc via a belt. The drive disc is fixed to the output end of the drive component fixedly installed inside the fulling machine housing. The drain pipe and the water injection pipe installed on the fulling machine housing are connected to the outer roller.

[0006] Preferably, the inner roller includes a roller body, mounting slots and holes, the rotating shaft on the roller body rotates through the outer roller and is fixedly connected to the driven disc, and a plurality of mounting slots and holes are provided through the roller body.

[0007] Preferably, one open end of the roller body is rotatably connected to the fulling machine housing, and the area corresponding to the opening of the roller body on the fulling machine housing is hinged and sealed with a roller cover; numerous holes are arranged between the mounting slots.

[0008] Preferably, the fulling adding mechanism installed on the fulling machine housing, inner roller, and outer roller includes an adding ring seat, a diverter pipe, an injection pipe, a deflector plate, an atomizing nozzle, and an inlet. Two adding ring seats are mirror-symmetrically fixedly installed inside the outer roller and are rotatably connected to the roller body. The two adding ring seats are connected by a diverter pipe, which passes through the outer roller and the fulling machine housing until it exits outside. The deflector plate is fixedly installed in the mounting slot provided in the roller body. Each deflector plate is provided with a plurality of atomizing nozzles, and each deflector plate has an inlet at both ends.

[0009] Preferably, the cross-section of the adding ring seat is a "U" shaped structure, and the area between the adding ring seats on the roller body is provided with numerous holes, and the inner area of ​​the outer roller between two adding ring seats is connected to the drain pipe.

[0010] Preferably, the adding ring seat is connected to the inlet provided at the end of the actuating plate, and the felting agent is pumped into the injection pipe and flows into the two adding ring seats through the diversion pipe, and enters the multiple actuating plates through the inlet.

[0011] Preferably, the actuating plate extends into the drum body, and the atomizing nozzles evenly arranged along its own length on the actuating plate are located inside the drum body.

[0012] Compared with the prior art, the present invention has the following beneficial effects: In this invention, the actuating plate of the fulling application mechanism extends into the inner roller, and the atomizing nozzles evenly arranged along the length of the actuating plate are located inside the roller body. This allows for direct spraying of atomized agents onto the wool fabric inside the inner roller, avoiding the limitations of traditional methods where the agent relies on the atomization flow of the outer roller to enter the inner roller. As the inner roller rotates, the actuating plate moves synchronously, enabling the atomizing nozzles to dynamically spray the agent during the rotation of the wool fabric. This ensures that the agent evenly covers all parts of the wool fabric, significantly improving the uniformity and quality of the fulling process.

[0013] This utility model features an additive ring seat with a "U"-shaped cross-section structure, connected to the inlet at the end of the actuating plate. The felting agent is pumped into the injection pipe, flows through the diversion pipe into the two additive ring seats, and then is evenly distributed to multiple actuating plates through the inlet. This diversion structure ensures the stability and uniformity of agent delivery, reducing leakage and loss during the delivery process. Simultaneously, the agent is sprayed directly inside the inner roller, avoiding residue on the inner wall of the outer roller or discharge with waste liquid, effectively saving agent and reducing production costs.

[0014] The mounting groove on the inner roller of this invention is used to hold and fix the agitator plate. When the inner roller rotates, the agitator plate not only serves as a carrier for the sprayed agent but also agitates and stirs the wool fabric, allowing the wool fibers to become more fully entangled and felted under the action of the agent. This combination of dynamic stirring and spraying further enhances the fulling effect, improving the fulling quality and production efficiency of wool fabrics. Attached Figure Description

[0022] As attached Figure 1 To be continued Figure 4 As shown: This utility model provides a chemical reagent addition device for wool fulling, comprising a fulling machine housing 1, an outer roller 2, a back plate 3, an inner roller 4, a fulling addition mechanism 5, a drain pipe 6, a water injection pipe 7, a driven disc 8, a belt 9, a drive disc 10, and a drive component 11. The outer roller 2 and the back plate 3 are fixedly installed inside the fulling machine housing 1. The inner roller 4 is rotatably installed inside the fulling machine housing 1 and the outer roller 2. The fulling addition mechanism 5 is installed on the fulling machine housing 1 and the inner roller 4. The rotating shaft of the inner roller 4 rotates through the outer roller 2 and is fixedly connected to the driven disc 8. The driven disc 8 is connected to the drive disc 10 through the belt 9. The drive disc 10 is fixed to the output end of the drive component 11 fixedly installed inside the fulling machine housing 1. The drain pipe 6 and the water injection pipe 7 installed on the fulling machine housing 1 are connected to the outer roller 2.

[0023] Furthermore, the inner roller 4 consists of a roller body 41, mounting slots 42, and holes 43. The roller body 41 is made of high-strength stainless steel, and its inner end shaft rotates through the side wall of the outer roller 2 via a bearing. The end of the shaft is fixedly connected to the driven plate 8 via a key, ensuring that the inner roller 4 can rotate synchronously with the driven plate 8. Several rectangular mounting slots 42 are evenly distributed along the circumference of the roller body 41 to engage and fix the actuating plate 54 of the felting and adding mechanism; the mounting slots 42 are regularly distributed with circular holes as holes 43.

[0024] Furthermore, the front opening of the roller body 41 is rotatably connected to the inner front wall of the fulling machine housing 1 via a deep groove ball bearing, ensuring the coaxiality of the inner roller 4 during rotation. A circular roller cover 12 is hinged to the area at the front of the fulling machine housing 1 corresponding to the opening of the roller body 41. An annular silicone sealing ring is embedded on the inner edge of the roller cover 12, forming a sealing fit with the opening end face of the roller body 41 to prevent liquid leakage during the fulling process. Mounting slots 42 extend axially along the roller body 41, and holes 43 are evenly distributed in the cylinder wall area between adjacent slots, allowing liquid exchange between the inner and outer rollers to occur during rotation of the inner roller 4.

[0025] Furthermore, the felting addition mechanism 5 includes symmetrically arranged addition ring seats 51, diversion pipes 52, injection pipes 53, actuating plates 54, atomizing nozzles 55, and inlets 56. The two addition ring seats 51 are made of corrosion-resistant polyvinyl chloride and have a U-shaped cross-section (opening towards the inner roller 4). They are fixed to the left and right sides of the inner wall of the outer roller 2 by bolts. A rotational gap is reserved between the inner ring of the ring seat and the outer wall of the roller body 41, and dynamic sealing is achieved through a graphite sealing ring. The two addition ring seats 51 are connected by the diversion pipe 52 in the middle. The diversion pipe 52 is made of pressure-resistant rubber tubing. The injection pipe 53, connected to the diversion pipe 52, is connected to an external reagent pump (not shown) via a quick-connect coupling. The actuating plate 54 is a long strip of plastic with a T-shaped cross-section. Its vertical section is fitted into the mounting groove 42 of the roller body 41; its horizontal section extends into the roller body 41, with a length accounting for 2 / 3 of the axial length of the inner roller 4. Multiple atomizing nozzles 55 (F-type fine mist nozzles) are evenly installed along the length of the horizontal section of each actuating plate 54, with the nozzle outlets facing the central axis of the inner roller 4. Inlet ports 56 are opened at both ends of the actuating plate 54, which are connected to the inner cavity of the adding ring seat 51 to realize the introduction of the agent.

[0026] Furthermore, the "U"-shaped structure of the adding ring seat 51 forms an independent reagent storage chamber. The area on the roller body 41 between the two adding ring seats 51 (i.e., the area of ​​the cylinder wall covered by the ring seats) is densely covered with holes 43, facilitating the entry of liquid from the outer roller 2 into the inner roller 4 through the holes 43. A drain pipe 6 is installed at the bottom of the outer roller 2, with its inlet located in the inner area of ​​the outer roller 2 between the two adding ring seats 51. A filter screen (not shown) is installed at the pipe opening to prevent fibrous impurities from clogging the pipe. The connection between the adding ring seat 51 and the outer roller 2 is sealed with epoxy resin to ensure no reagent leakage.

[0027] Furthermore, the inner cavity of the adding ring seat 51 is connected to the internal flow channel of the actuating plate 54 through the inlet 56. The actuating plate 54 has a through-flow channel with a diameter of 8 mm inside, and the end of the flow channel is threadedly connected to the liquid inlet of the atomizing nozzle 55. After being pressurized by an external plunger pump (not shown), the felting agent enters the distribution pipe 52 through the injection pipe 53. The distribution pipe 52 evenly distributes the agent to the left and right adding ring seats 51. After a brief buffering in the inner cavity of the ring seat, the agent flows into the flow channel of the actuating plate 54 through the inlet 56, and is finally sprayed out by the atomizing nozzle 55 at a pressure of 0.3-0.5 MPa, forming droplets with a particle size of 50-100 μm.

[0028] Furthermore, the actuating plates 54 are evenly distributed along the axial direction of the inner roller 4, with a quantity of 4-12, corresponding one-to-one with the number of mounting slots 42. The atomizing nozzle 55 of each actuating plate 54 is installed at a 45° angle, with the nozzle axis making a 30° angle with the radial direction of the inner roller 4, ensuring that the droplets can cover different areas of the inner wall of the roller body 41. When the inner roller 4 rotates, the actuating plates 54 rotate synchronously with the roller, and the atomizing nozzles 55 form a dynamic spray trajectory under centrifugal force, causing the pesticide droplets to adhere evenly to the surface of the wool fabric. The actuating plates 54 are made of antistatic modified polypropylene material to avoid electrostatic adsorption of fibers affecting the spraying effect.

[0029] The working principle is as follows: First, open the roller cover 12 hinged to the front end of the fulling machine housing 1, put the coarse wool fabric to be fulled into the roller body 41 of the inner roller 4, and then close the roller cover 12 so that the annular silicone sealing ring on the inner side of the roller cover 12 seals with the opening end face of the roller body 41 to prevent liquid from overflowing.

[0030] Next, the drive component 11 (motor) fixedly installed inside the fulling machine housing 1 is started. The output end of the drive component 11 drives the drive disc 10 to rotate, and transmits the power to the driven disc 8 through the belt 9, thereby driving the shaft of the inner roller 4 to rotate, so that the inner roller 4 rotates between the inner roller 4 and the outer roller 2 at a speed of 50-100 r / min.

[0031] During the felting process, an external plunger pump (not shown) pressurizes the felting agent and then inputs it into the distribution pipe 52 through the injection pipe 53. The distribution pipe 52 evenly distributes the agent into the addition ring seats 51 on both sides of the inner wall of the outer roller 2. After a brief buffering in the "U"-shaped storage cavity of the addition ring seat 51, the agent flows into the through-flow channel inside through the inlets 56 at both ends of the actuating plate 54, and is finally sprayed out by the F-type fine mist nozzles 55 evenly installed on the horizontal section at a pressure of 0.3-0.5MPa, forming droplets with a particle size of 50-100μm.

[0032] Since the actuating plate 54 is locked in the mounting slot 42 of the roller body 41 and rotates synchronously with the inner roller 4, its horizontal section extends into the inside of the roller body 41, and the atomizing nozzle 55 is installed at a 45° angle toward the central axis of the inner roller 4, under the action of centrifugal force, the droplets can form a dynamic spray trajectory covering different areas of the inner wall of the roller body 41, and directly and evenly adhere to the surface of the rotating wool fabric.

[0033] Meanwhile, clean water or other treatment liquid is injected into the outer roller 2 through the water injection pipe 7. The liquid enters the inner roller 4 through the dense holes 43 located between the two adding ring seats 51 on the roller body 41, and works together with the agent on the wool fabric. When the inner roller 4 rotates, the agitator plate 54 not only serves as a carrier for agent spraying, but its own agitation of the wool fabric can also promote fiber entanglement and felting, and enhance the felting effect.

[0034] After the fulling process is completed, the drive unit 11 stops operating, the drain pipe 6 is opened, and the waste liquid (including residual agents and impurities) in the outer roller 2 is discharged through the drain pipe 6 inlet and filter screen (not shown) in the area between the adding ring seat 51, thus completing the entire fulling process.

[0035] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
