Description

Technical Field

[0001] This invention relates to the field of fabric production, specifically to a production process for a volcanic rock heating fabric. Background Technology

[0002] Currently, in the production and manufacturing of nonwoven fabrics, polypropylene spunbond nonwoven fabrics often exhibit uneven fabric distribution across the entire width during the web laying process. This manifests as thinner ends with a weight significantly lower than the set production weight, referred to as "burrs." These burrs, failing to meet production requirements, need to be trimmed and aligned. During the setting process, the burrs on the edges, being too thin, can leave loose fibers adhering to the rolling mill after heat treatment. If not removed promptly, this can easily cause tearing and breakage of the nonwoven fabric, potentially leading to machine downtime or damage, thus affecting the stability of the production line and the safety of the equipment.

[0003] The currently disclosed Chinese patent CN219385541U discloses a burr-blowing and finishing device for a spunbond nonwoven fabric production line, comprising a main sliding device, a blower pipe, a blower pipe support, a micro air pump, and a lead screw. Two lead screws are respectively positioned on opposite sides of the nonwoven fabric movement direction on the production line platform, and a drive motor is installed at the end of each lead screw. The main sliding device is mounted on the lead screw. The blower pipe is rotatably connected to the main sliding device via the blower pipe support. The micro air pump is connected to the blower pipe. Through this method, the blower pipe can blow and finish the burrs, making them neat, reducing weight differences, and preventing them from adhering to the pattern roller.

[0004] According to the aforementioned patent, the brushed edge finishing device can finish the low-weight brushed edges, reduce the weight difference, make the brushed edges cleaner, and prevent them from sticking to the pattern roller. However, brushed edge finishing may take a long time to achieve the desired effect, especially when processing large areas or continuous production lines, which may reduce production efficiency. Therefore, there is a need for an automated trimming device to precisely cut off the brushed edges, ensure that the edges are flat, and ensure that the cut-off brushed edges do not affect the next process of fabric production, thus ensuring that the edges are flat without affecting the fabric production efficiency. Summary of the Invention

[0005] To address the problems existing in the current technology, this invention provides a production process for volcanic rock heating fabric. During the trimming of the raw fabric edges, the present invention uses a blocking component to confine the trimmed lint in a temporary space, preventing the lint from adhering to the surface of the raw fabric and avoiding the raw fabric edges from being caught and torn in subsequent steps, thereby improving production efficiency and the final fabric production quality.

[0006] To address the problems of existing technologies, this invention provides a production process for volcanic rock heating fabric, comprising the following steps: Step 1: Fabric preparation, selecting a suitable volcanic rock heating fabric blank;

[0007] Step 2: Fabric pretreatment, including trimming and impurity removal of the fabric;

[0008] Step 3: Dyeing. The treated fabric is dyed by selecting a suitable dye.

[0009] Step 4: Post-treatment, which involves shaping, waterproofing, oil-proofing, and wrinkle-resistant treatments on the dyed fabric.

[0010] Step 5: Rinse with water to remove excess dye and chemical residues;

[0011] Step 6: Moisture-absorbing and heat-generating finishing, using a moisture-absorbing and heat-generating finishing agent to treat the fabric through impregnation, baking, and other methods;

[0012] Step 7: Shaping, using high-temperature steam to fix the shape of the fabric;

[0014] Step 9: Warehousing. Store the inspected and qualified fabrics in the warehouse, and properly label and classify them.

[0015] In step 2, the pre-treatment device for the fabric includes a feeding roller and a winding roller for conveying the fabric. A rough edge treatment mechanism is provided between the feeding roller and the winding roller on both sides of the fabric. A base is provided on both sides of the fabric along its edge direction for mounting the corresponding rough edge treatment mechanism. The rough edge treatment mechanism includes an air knife sprayer set on the base and a blocking component for preventing the trimmed lint from adhering to the surface of the fabric. A temporary space is formed between the blocking component and the base for the rough edge to pass through and be treated.

[0016] Preferably, the blocking assembly includes baffles symmetrically arranged on the upper and lower surfaces of the fabric. The baffles are used to prevent the trimmed lint from drifting inward and adhering to the surface of the fabric. The baffles extend from one end of the base to the other end along the direction in which the fabric is rolled up. The baffles have a contact surface that fits against the surface of the fabric. The temporary space is formed between the base and all the baffles.

[0017] Preferably, the baffle is rotatable relative to the fabric, the baffle has a rotation axis along its length, the base is provided with a shaft connection for rotatably connecting the rotation axis, and the base is also provided with a pressing connector to ensure that the contact surface of the baffle is in contact with the surface of the fabric.

[0018] Preferably, the pressing connector is a torsion spring, one end of the rotating shaft extends outward through the corresponding shaft joint, and the torsion spring is sleeved on the extended end of the rotating shaft and fixedly connected between the shaft joint and the rotating shaft.

[0019] Preferably, the blocking assembly further includes guide plates symmetrically arranged on the upper and lower surfaces of the fabric. The guide plates are used to block lint adhering to the edge of the fabric from being introduced into the next process along with the fabric. The guide plates are located at one end of the base near the take-up roller. One end of the guide plate extends to the inside of the baffle, and the other end extends to the outside of the baffle beyond the edge of the fabric. The guide plates have a pressing surface that fits against the surface of the fabric.

[0020] Preferably, the guide plate is movable perpendicular to the surface of the fabric, and the end of the guide plate extending inward toward the baffle has a movable block. The movable block has a guide rod extending outward perpendicular to the surface of the fabric. A guide sleeve is provided on the base for the guide rod to slide therein. The base is also provided with a pressing connector to ensure that the pressing surface of the guide plate is in contact with the surface of the fabric.

[0021] Preferably, the pressing connector is a compression spring, which is sleeved on the guide rod and fixedly connected between the guide sleeve and the movable block.

[0022] Preferably, the movable block has air holes along the extension direction of the guide plate to blow out the accumulated lint from the inside out.

[0023] Preferably, the base has a support portion along its length for supporting the rough edges of the fabric, and the base also has an air inlet channel that is connected to the air knife injector and perpendicular to the support portion.

[0024] Preferably, the base has an air outlet channel along its length that allows lint in the temporary storage space to be discharged, and the base is provided with a negative pressure actuator that communicates with the air outlet channel.

[0025] The advantages of this application compared to the prior art are:

[0026] 1. The present invention uses a blocking component to confine the trimmed lint in a temporary space during the trimming process of the raw fabric edge, preventing the lint from adhering to the surface of the raw fabric. Compared with the traditional air-blowing finishing method, the air knife trimming method can complete the raw edge trimming work faster and avoid the situation where the trimmed raw edge is hooked and torn in subsequent steps, thus avoiding production accidents, improving production efficiency and the final fabric production quality.

[0027] 2. The present invention, through the cooperation between the baffle and the torsion spring, ensures that the contact surface of the baffle is tightly attached to the surface of the fabric, preventing gaps between the baffle and the fabric, blocking the trimmed lint in the temporary storage space, and preventing lint from adhering to the surface of the fabric through the gap between the baffle and the fabric, which is beneficial to the production of the fabric in the next process and improves the production quality.

[0028] 3. This invention, through the cooperation between the guide plate and the compression spring, ensures that the pressing surface of the guide plate is tightly attached to the surface of the fabric, preventing gaps between the guide plate and the fabric. This scrapes off the lint attached to the edge of the fabric, preventing the lint from following the fabric into the next process through the gap between the guide plate and the fabric. Air is supplied through the air holes to blow the lint outward, avoiding the accumulation of lint beyond the guide plate. Combined with the function of the baffle, this ensures that the lint generated after trimming the raw edges of the fabric is effectively removed, which is beneficial to the production of the fabric in the next process and improves the production quality.

[0039] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0040] See Figures 1-4 As shown, a production process for a volcanic rock heating fabric includes the following steps:

[0041] Step 1: Prepare the fabric, select a suitable volcanic rock heating fabric greige fabric 1;

[0042] Step 2: Pre-treatment of the greige fabric, trimming and removing impurities from greige fabric 1;

[0043] Step 3: Dyeing. The treated greige fabric 1 is dyed by selecting a suitable dye.

[0044] Step 4: Post-treatment, which involves shaping, waterproofing, oil-proofing, and wrinkle-resistant treatments on the dyed fabric.

[0045] Step 5: Rinse with water to remove excess dye and chemical residues;

[0046] Step 6: Moisture-absorbing and heat-generating finishing, using a moisture-absorbing and heat-generating finishing agent to treat the fabric through impregnation, baking, and other methods;

[0047] Step 7: Shaping, using high-temperature steam to fix the shape of the fabric;

[0048] Step 8: Inspect the packaging and conduct a quality inspection of the fabric, including checking the color, size, and feel.

[0049] Step 9: Warehousing. Store the inspected and qualified fabrics in the warehouse, and properly label and classify them.

[0050] In step 2, the pre-treatment device for the fabric includes a feeding roller 2 and a take-up roller 3 for conveying the fabric 1. A rough edge treatment mechanism 4 is provided between the feeding roller 2 and the take-up roller 3 on both sides of the fabric 1. A base 5 is provided on both sides of the fabric 1 along its edge direction for mounting the corresponding rough edge treatment mechanism 4. The rough edge treatment mechanism 4 includes an air knife sprayer provided on the base 5 and a blocking component 41 for preventing the trimmed lint from adhering to the surface of the fabric 1. A temporary space 42 is formed between the blocking component 41 and the base 5 for the rough edge to pass through and be treated.

[0051] In the production process of volcanic rock heating fabric, the greige fabric is prepared and transported via conveyor equipment. During the pretreatment of the greige fabric, the raw edges of the dried greige fabric 1 are first trimmed. Then, a scouring agent and degreasing agent are added at room temperature. After the fabric is thoroughly wetted, tea saponin is added, the temperature is raised to 70℃, hydrogen peroxide is added, and then the temperature is raised to 98℃ and held for 50 minutes. The temperature is then lowered to 60℃ and drained. Glacial acetic acid is added to the incoming water, the temperature is raised to 80℃ and held for 10 minutes, and then drained. Next, the fabric is washed with room temperature water for 5 minutes and drained before dyeing. During the dyeing process, dye and sodium sulfate are added at room temperature, the temperature is raised to 60℃, soda ash is added, and the temperature is held for 30-80 minutes before draining. Wash for 10 minutes, add glacial acetic acid, heat to 50℃, keep warm for 10 minutes, drain. Wash for 10 minutes, add soap, heat to 95℃, keep warm for 15 minutes, drain. Wash again, heat to 80℃, keep warm for 10 minutes, drain. Rinse with water for 10 minutes, drain. After cleaning, add a moisture-absorbing finishing agent. Before adding the moisture-absorbing and heat-generating finishing agent, the fabric surface must be thoroughly cleaned to remove any residual color or additives. Add 15% moisture-absorbing and heat-generating finishing agent RK-B and 0.4% RK-J at room temperature. After dilution, they can be added together with RK-B to adjust the pH value to 6-8. Then run at room temperature for 20 minutes, remove the fabric, squeeze out water, dry, and bake. The baking temperature is controlled at 150℃, and the machine speed is 15 meters / minute. After baking, the fabric needs to undergo alkaline cleaning (2g / L soda ash, 60℃*20'), followed by water washing and hot water washing until the alkali is completely removed. The fabric is then shaped, and tests are conducted on the volcanic rock heating fabric. Simultaneously, ordinary yarn fabrics of the same specification are sampled for comparison testing. According to GB / T30127 and FZ / TGB / T1048 testing standards, fabrics that pass the tests and are deemed qualified are stored in the warehouse. During the pre-treatment of the greige fabric, the rough edges are trimmed. Specifically, the greige fabric 1 is transferred from the feeding roller 2 to the winding roller 2. During the winding process of the fabric 1 and roller 3, the rough edges of the fabric 1 pass through the temporary space 42 formed between the blocking component 41 and the base 5. During this process, the air knife jet is stationary relative to the fabric 1 being transported. The air knife jet is activated and the shearing force generated by the high-speed airflow is used to precisely cut off the rough edges of the fabric 1. The air knife jet is not shown in the figure. After the rough edges are cut off, the blocking component 41 restricts the cut lint from drifting inward and adhering to the surface of the fabric 1. Therefore, while ensuring the edge is flat, the lint generated is left in the temporary space 42 and does not affect the subsequent production of the fabric.

[0052] See Figures 3-6 As shown, the blocking assembly 41 includes baffles 411 symmetrically arranged on the upper and lower surfaces of the fabric 1. The baffles 411 are used to prevent the trimmed lint from drifting inward and adhering to the surface of the fabric 1. The baffles 411 extend from one end of the base 5 to the other end along the direction in which the fabric 1 is rolled up. The baffles 411 have a contact surface that fits against the surface of the fabric 1. The temporary space 42 is formed between the base 5 and all the baffles 411.

[0053] During the process of the fabric 1 being transferred from the feed roller 2 to the take-up roller 3, the edges of the fabric 1 on both sides are trimmed by the air knife jet. Due to the presence of the baffles 411 on the upper and lower surfaces of the fabric 1, the lint that has been cut off is prevented from drifting inward and adhering to the surface of the fabric 1 under the action of the air knife jet. Instead, it is stored in the temporary space 42 for subsequent processing. Furthermore, since the baffles 411 have a contact surface that fits against the surface of the fabric 1, it is ensured that the baffles 411 can make close contact with the surface of the fabric 1, avoiding the possibility of lint drifting inward due to gaps between the baffles 411 and the fabric 1.

[0054] See Figures 3-6 As shown, the baffle 411 is rotatable relative to the fabric 1. The baffle 411 has a rotation shaft 412 along its length direction. The base 5 is provided with a shaft connection 4121 for rotatably connecting the rotation shaft 412. The base 5 is also provided with a pressing connector 4111 to ensure that the contact surface of the baffle 411 is in contact with the surface of the fabric 1.

[0055] The baffle 411 rotates on the shaft joint 4121 via the rotating shaft 412 to adapt to different thicknesses of the fabric 1. Under the action of the pressing connector 4111, it ensures that the contact surface is always tightly attached to the surface of the fabric 1, thereby avoiding the possibility of gaps. The cut-off lint is left in the temporary space 42 under the action of the baffle 411.

[0056] See Figures 3-6 As shown, the pressing connector 4111 is specifically a torsion spring. One end of the rotating shaft 412 extends outward through the corresponding shaft connection 4121. The torsion spring is sleeved on the extended end of the rotating shaft 412 and is fixedly connected between the shaft connection 4121 and the rotating shaft 412.

[0057] The torsion spring provides the baffle 411 with the pressure against the fabric 1. The torsion of the torsion spring acts on the baffle 411, so that the contact surface of the baffle 411 can always be tightly attached to the surface of the fabric 1. When the thickness of the fabric 1 changes, the torsion of the torsion spring can adjust the position of the baffle 411 to ensure that the contact pressure between the baffle 411 and the fabric 1 is constant, thereby avoiding the generation of gaps.

[0058] See Figures 7-10 As shown, the blocking assembly 41 also includes guide plates 413 symmetrically arranged on the upper and lower surfaces of the fabric 1. The guide plates 413 are used to prevent lint attached to the edge of the fabric 1 from being introduced into the next process along with the fabric 1. The guide plates 413 are located at one end of the base 5 near the take-up roller 3. One end of the guide plates 413 extends to the inner side of the baffle 411, and the other end extends to the outer side of the baffle 411 beyond the edge of the fabric 1. The guide plates 413 have a pressing surface that is in contact with the surface of the fabric 1.

[0059] If some lint is attached to the edge of the fabric 1 in the temporary space 42 during the winding process, the lint will be blocked when the fabric 1 passes through the guide plate 413. Since the pressing surface of the guide plate 413 is in close contact with the surface of the fabric 1, the lint will be scraped off when the guide plate 413 descends in a stationary state relative to the fabric 1, and will not follow the fabric 1 into the next process, thus avoiding interference from the lint in subsequent processes.

[0060] See Figures 7-10 As shown, the guide plate 413 can move perpendicular to the surface of the fabric 1. The end of the guide plate 413 extending inward toward the baffle 411 has a movable block 414. The movable block 414 has a guide rod 4141 extending outward perpendicular to the surface of the fabric 1. The base 5 is provided with a guide sleeve 4142 for the guide rod 4141 to slide therein. The base 5 is also provided with a pressing connector 4131 to ensure that the pressing surface of the guide plate 413 is in contact with the surface of the fabric 1.

[0061] The guide plate 413, through the movement of the guide rod 4141 on the guide sleeve 4142 and in conjunction with the action of the pressing connector 4131, adapts to different thicknesses of the fabric 1. Under the action of the pressing connector 4131, it ensures that the pressing surface is always tightly attached to the surface of the fabric 1, thereby avoiding the possibility of a gap between the guide plate 413 and the fabric 1. As the lint is conveyed along the edge of the fabric 1, it is scraped off by the obstruction of the guide plate 413, keeping it stationary and preventing it from following the fabric 1 into the next process. (See also...) Figures 7-10 As shown, the pressing connector 4131 is specifically a compression spring, which is sleeved on the guide rod 4141 and fixedly connected between the guide sleeve 4142 and the movable block 414.

[0062] The compression spring provides the guide plate 413 with the pressure against the fabric 1. The elastic force of the compression spring acts on the guide plate 413, so that the pressure surface of the guide plate 413 can always be in close contact with the surface of the fabric 1. When the thickness of the fabric 1 changes, the elastic force of the compression spring can adjust the position of the guide plate 413 to ensure that the contact pressure between the guide plate 413 and the fabric 1 is constant, thereby avoiding the generation of gaps and effectively scraping off the lint attached to the edge of the fabric 1.

[0063] See Figure 7 and Figure 8 As shown, the movable block 414 has air holes 4143 along the extension direction of the guide plate 413 for blowing out the accumulated lint from the inside to the outside.

[0064] As the fabric 1 is being transported, air is supplied through the air holes 4143 via a connected air pump (not shown in the figure). Air is blown through the air holes 4143 along the extension direction of the guide plate 413, causing the blocked lint to be blown out to areas outside the edge of the fabric 1. This prevents the lint from accumulating too much and drifting across the guide plate 413 onto the surface of the fabric 1 and entering the next process with it.

[0065] See Figure 5 As shown, the base 5 has a support portion 51 along its length for supporting the rough edges of the fabric 1, and the base 5 also has an air inlet channel 52 that is connected to the air knife injector and is perpendicular to the support portion 51.

[0066] As the air knife jet is activated, air is directed through the air inlet channel 52 to impact the support part 51, allowing high-pressure gas to be sprayed directly perpendicular to the rough edge of the fabric 1. This vertical spraying method can powerfully act on the rough edge, achieving a more effective removal of the rough edge and effectively blowing the rough edge away from the fabric 1.

[0067] See Figure 5 As shown, the base 5 has an air outlet channel 53 along its length that allows lint in the temporary storage space 42 to be discharged. The base 5 is provided with a negative pressure actuator that communicates with the air outlet channel 53.

[0068] The negative pressure actuator is not shown in the figure. When the rough edge is cut off, the negative pressure actuator is activated and generates negative pressure through the air outlet channel 53 to suck out the lint generated after the rough edge is cut off in the temporary storage space 42. This is beneficial for continuous cutting of the rough edge and avoids the accumulation of lint in the temporary storage space, which affects the operation of the air knife jet and improves the trimming effect of the rough edge of the fabric 1.

[0069] During the trimming of the raw edges of the fabric 1, the present invention uses the blocking component 41 to confine the trimmed lint in the temporary space 42, preventing the lint from adhering to the surface of the fabric 1. Compared with the traditional air-blowing finishing method, the air knife trimming method can complete the raw edge trimming work faster, and also avoids the situation where the trimmed raw edges are hooked and torn in subsequent steps, thus avoiding production accidents, improving production efficiency and the final fabric production quality.

[0070] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
