Description

Technical Field

[0001] This utility model relates to the field of fabric processing technology, specifically to a cold-batch impregnation and padding machine for raw fabric. Background Technology

[0002] The cold padding mill for raw fabric is a key device in the dyeing and finishing of fabrics. Its pretreatment requires the cooling liquid to be evenly applied to the surface of the raw fabric through the padding mill, so as to provide the necessary chemical environment and humidity conditions for the subsequent low-temperature stacking reaction.

[0003] A search revealed that Chinese utility model patent application CN218465117U proposes a "cold stacking treatment device for oiled polyester yarn". The device is equipped with multiple feeding devices arranged in a front-to-back configuration to effectively stretch the yarn that needs to be wound. The multiple feeding rollers are connected to the side frame via grooves and rollers to facilitate the forward and backward movement of the device. At the same time, the rear feeding roller in the feeding device is rotatably connected to the top of the base via a mounting frame, allowing the entire rear feeding roller to rotate. In conjunction with a pushing device on one side, the rear feeding roller can be oscillated back and forth with a small amplitude.

[0004] However, in actual use, the aforementioned disclosed devices and similar existing devices either use a continuous spray nozzle to release the coolant, maintaining a constant flow rate regardless of whether the fabric passes through, resulting in a large amount of coolant being lost directly without contacting the fabric, causing a waste of resources, or use an indirect cooling method by circulating liquid inside the roller, where the heat transfer efficiency is limited by the roller material and the contact area with the fabric, easily leading to uneven temperature distribution on the surface of the fabric. Summary of the Invention

[0005] The purpose of this invention is to provide a cold-batch impregnation and rolling mill for raw fabric to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A cold-batch processing impregnation mill for raw fabric includes: a fabric impregnation mill, wherein a processing component is assembled above the position of the winding raw fabric roller; The processing component includes: A storage pipe, used to temporarily store coolant, is assembled into the assembly notch above both ends of the fabric impregnation mill frame through a water-passing connector fixed at both ends. The surface of the storage tube is provided with a contact element, and several discharge gaps are provided on the surface of the storage tube near the contact element. Each discharge gap is equipped with a miniature pressure valve. The fabric wraps around the processing components and coils around the roller surface. When the fabric impregnation mill is running, the roller rotates and the fabric is conveyed at a constant speed along its roller surface. The fabric rolls against the contact parts on the surface of the storage tube. As the fabric moves, the contact parts are squeezed by the fabric, causing the internal pressure of the storage tube to change. This triggers the micro pressure valve to open, and the coolant is released evenly onto the fabric surface in a mist or column through the discharge notch, forming a continuous cold treatment zone.

[0007] Furthermore, the contact element includes: A connecting pin has one end that passes through the storage tube and is fixed to a contact arc plate. Several discharge notches are located adjacent to the surface area of ​​the storage tube corresponding to the contact arc plate. The arc surface of the contact arc plate matches the arc of the roller. The other end of the connecting pin is placed inside the storage tube and is fixedly connected to a pressure arc plate. A return spring, sleeved on the outside of the connecting pin, is fixed between the pressure arc plate and the inner wall of the storage tube.

[0008] Furthermore, the water-connecting fitting includes: A positioning tube is used to fit the assembly notch and is coaxially fixed at the opening of the storage tube and connected to the storage tube. The channel valve pipe is coaxially rotatably connected to the inlet of the positioning pipe and communicates with the positioning pipe. The channel valve pipe is used to connect to an external coolant delivery device.

[0009] Furthermore, a positioning bolt is inserted at the top of the fabric impregnation machine frame at the position of the assembly notch. The positioning bolt is threadedly connected to a threaded through hole opened at the position of the assembly notch on the top of the frame. The end of the positioning bolt extends into the assembly notch and abuts against the top outer wall of the positioning tube, thereby confining the positioning tube in the assembly notch.

[0010] Furthermore, the processing components are provided in several parts, which are evenly spaced along the axial direction of the roller. Each processing component covers a different width area of ​​the fabric. The discharge gaps of adjacent processing components partially overlap to avoid cold treatment blind spots on the surface of the fabric.

[0011] Furthermore, the inner wall of the storage tube is fitted with an insulation layer made of polyurethane foam to slow down the rise in coolant temperature and maintain the stability of the cold treatment effect. The arc surface of the contact arc plate is covered with an anti-slip rubber pad, and the surface of the rubber pad has several grooves to increase the friction between it and the fabric.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This cold-batch impregnation mill for raw fabric releases coolant by using a micro-pressure valve to release coolant through the rolling contact between the contact component and the raw fabric in the processing assembly. This achieves on-demand release of coolant, avoiding the waste of coolant caused by continuous spraying in traditional impregnation mills. At the same time, the mist or columnar release method ensures that the coolant evenly covers the surface of the raw fabric, solving the problem of inconsistent partial temperature of the raw fabric in the existing cold treatment process. In addition, the arrangement of several processing components evenly spaced along the roller axis and with partial overlap of adjacent release ranges effectively eliminates the cold treatment blind spots on the surface of the fabric, ensuring the consistency of the overall cold treatment of the fabric. The polyurethane foam insulation layer attached to the inner wall of the storage tube slows down the rate of temperature rise of the coolant, maintains the stability of the cold treatment effect, and solves the problem of unstable cold stacking quality caused by easy fluctuation of coolant temperature in existing equipment. The anti-slip rubber pads and surface grooves covering the arc surface of the contact plate increase the friction between the contact plate and the fabric, preventing the fabric from sliding or shifting during transport and ensuring the stability of the impregnation mill. The coaxial rotating connection between the channel valve pipe and the positioning pipe in the water connector facilitates the installation and adjustment of the external coolant delivery pipe. The positioning bolts, which are fixed by threaded connection to the positioning pipe, make the assembly and disassembly of the processing components more convenient and improve the maintenance efficiency of the equipment.

[0015] 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.

[0016] Before understanding the technical solution proposed in this application, it should be clear that the application scenario of this technical solution is specifically the padding stage in the cold piling process of raw fabric. Specifically, it is applied to the padding treatment of raw fabric before cold piling in the printing and dyeing process. After the raw fabric is impregnated with the treatment liquid by the padding machine, the raw fabric is uniformly cooled by the treatment component 3 to meet the temperature requirements of the raw fabric in the cold piling process.

[0017] like Figures 1 to 3 As shown, the technical solution proposed in this application is a cold-batch processing impregnation machine for raw fabric, specifically including: a fabric impregnation machine 1. It should be noted that the fabric impregnation machine 1 is a piece of equipment used in the prior art for impregnating raw fabric in the processing of raw fabric, including a frame, rollers for placing and conveying the raw fabric, and a power source for driving the rollers to rotate. Based on the existing fabric impregnation machine 1, this utility model adds a processing component 3 above the rollers that wind the raw fabric to meet the needs of cold-batch processing of raw fabric. The processing component 3 mainly consists of the following parts: As a core component, the storage tube 301 is used to temporarily store coolant for cold treatment. The storage tube 301 is securely assembled into the pre-opened assembly notches 2 above both ends of the fabric impregnation machine 1 frame through water-passing connectors fixed at both ends of its pipe openings.

[0018] It should be added that a contact element is movably inserted on the surface of the storage tube 301, and several discharge notches are opened on the surface of the storage tube 301 near the contact element. A miniature pressure valve 305 is precisely installed in each discharge notch.

[0019] It is worth noting that during actual operation, the fabric bypasses the processing component 3 and coils around the roller surface. When the fabric impregnation mill 1 starts, the roller rotates accordingly, driving the fabric forward at a constant speed along its surface. During this process, the moving fabric rolls against the contact element on the surface of the storage tube 301. As the fabric continues to move, the contact element is subjected to the squeezing force exerted by the fabric. This squeezing directly causes a change in the internal pressure of the storage tube 301, triggering the opening of the miniature pressure valve 305 assembled at the discharge gap. Once the valve opens, the coolant temporarily stored in the storage tube 301 is released evenly through the discharge gap in a finely controlled mist or stable columnar form and covers the surface of the moving fabric below, thereby forming a continuous and uniform cold treatment area on the fabric.

[0020] As a supplement to the above, in this technical solution, the contact element specifically includes: The connecting pin 306 penetrates the wall of the storage tube 301 at one end and is firmly connected to a contact arc plate 303 on the outside. It is worth noting that several discharge gaps are concentrated on the surface area of ​​the storage tube 301 corresponding to the contact arc plate 303. The arc surface design of the contact arc plate 303 has been calculated to ensure that it matches the arc height of the roller below in order to achieve the contact effect.

[0021] Furthermore, it should be noted that the other end of the connecting pin 306 is located inside the storage tube 301, and a pressure arc plate is fixedly connected to this end. A return spring 307 is securely fitted between the pressure arc plate and the inner wall of the storage tube 301. The spring surrounds the outside of the connecting pin 306. When the fabric presses against the contact arc plate 303, the pressure is transmitted to the pressure arc plate through the connecting pin 306, compressing the return spring 307. When the pressing is released, the elastic force of the return spring 307 pushes the entire contact part back to its original position.

[0022] As a further supplement to the above, the water connection fittings include: The positioning tube 302 is precisely fitted to the assembly notch 2 on the frame. The positioning tube 302 is coaxially fixed at the opening of the storage tube 301 and maintains communication with the inside of the storage tube 301. The channel valve tube 304 is coaxially rotatably connected to the opening of the positioning tube 302 and also maintains communication with the positioning tube 302. The main function of this channel valve tube 304 is to connect to the external coolant delivery system so as to continuously replenish coolant into the storage tube 301.

[0023] To ensure the stability of the processing component 3 during equipment operation, a positioning bolt 4 is inserted at the top of the fabric impregnation mill 1 frame, at the position of the assembly notch 2. This positioning bolt 4 is threaded into a specially opened threaded through hole at the position of the assembly notch 2 on the top of the frame. It is worth noting that after tightening the positioning bolt 4, its end will extend into the assembly notch 2 and tightly abut against the top outer wall of the positioning tube 302, thereby firmly confining the entire positioning tube 302 (together with the processing component 3) within the assembly notch 2 and preventing it from shifting during operation.

[0024] To achieve a comprehensive and uniform cold treatment effect, several treatment components 3 are provided. These treatment components 3 are evenly spaced along the axial direction of the roller. Each treatment component 3 operates independently and is responsible for covering different width areas of the fabric surface. More importantly, the range of coolant released by the discharge gaps of adjacent treatment components 3 is designed to have some overlap. This overlapping layout strategically avoids possible cold treatment blind spots on the fabric surface in the width direction, ensuring the continuity of the cold treatment effect along the width of the fabric.

[0025] To maintain the stability of the cooling effect, an insulation layer is attached to the inner wall of the storage tube 301. This insulation layer is made of polyurethane foam, which can effectively slow down the temperature rise of the coolant inside the storage tube 301 caused by ambient heat, ensuring that the coolant is always at the required low temperature. In addition, the arc surface of the contact arc plate 303 is covered with a layer of anti-slip rubber pad. The surface of the rubber pad has several strip groove textures. These grooves significantly increase the friction between the contact arc plate 303 and the surface of the moving fabric, preventing slippage and ensuring the effectiveness of pressure transmission and the reliability of contact.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
