Description

Technical Field

[0001] This invention relates to the field of base fabric production technology, and more specifically to a solid transfer high-peel base fabric production process. Background Technology

[0002] The two-point bonding process typically involves pre-coating treatment, slurry application, powder application, powder absorption, drying, and sintering. When processing the base fabric, hot melt adhesive powder needs to be sprinkled onto the base fabric after slurry application and dried before proceeding to the next step. However, when applying hot melt adhesive powder, uneven slurry application and high moisture content of the adhesive dots often occur.

[0003] A Chinese invention patent with publication number CN108160418A discloses a base fabric production and processing equipment, including a frame, a powder storage chamber, a powder spreading device, a first conveying mechanism, a second conveying mechanism, and a powder suction device. The powder spreading device is equipped with an auxiliary powder storage box, which contains a feeding roller assembly. A second discharge hopper is located at the bottom of the auxiliary powder storage box. The first conveying mechanism is located below the powder spreading device and cooperates with the second conveying mechanism. The powder suction device is located on the second conveying mechanism. The weight of the powder material in the auxiliary powder storage box is controlled by the feeding roller assembly, and uniform powder spreading is achieved in combination with a vibrating screen. An electromagnetic coil drive assembly cooperates with spaced drive strips to achieve regular vibration of the second grid conveyor belt. With the help of three blowing and two suction, excess powder particles can be recovered in time.

[0004] However, the inventors discovered that in the actual powdering process, the adhesive powder is always applied in a direction perpendicular to the base fabric and downwards. Due to the different surface temperatures of the paste dots, the temperature in the middle part is higher than that on both sides, resulting in different adhesion between the paste dot surface and the adhesive powder, which makes the coating of the adhesive powder on the paste dot surface worse. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a solid transfer high-peelability base fabric production process. This process involves a transfer component that quantitatively transfers adhesive powder onto the base fabric while a negative pressure component adsorbs and fixes the adhesive powder on the base fabric, preventing dispersion. A vibration component ensures that the powder clumps fall more completely into the transfer tank, and the adhesive powder falls from the transfer tank onto the base fabric at a faster speed, guaranteeing that all the adhesive powder lands on the base fabric and improving the transfer effect.

[0006] The technical solution of the present invention is as follows:

[0007] A solid transfer high-peelability substrate production process includes the following steps:

[0008] Step 1, Transfer Process: The powder clumps are quantitatively transferred onto the base fabric using a powder clump transfer device;

[0009] Step 2, Preheating process: The base fabric is placed in the preheating box for preheating, so that the powder initially melts and adheres to the base fabric;

[0010] Step 3, Powdering process: Apply adhesive powder to the dough using a powdering machine, so that new adhesive powder adheres to the surface of the molten dough;

[0011] Step 4, Powder blowing and suction process: Excess adhesive powder on the base fabric is absorbed by the blowing and suction device;

[0012] Step 5, Heating Process: The adhesive powder is baked again in a heating box to bond it to the base fabric;

[0013] Step 6, Cooling process: The fused base fabric is cooled and shaped by cooling rollers.

[0014] As a preferred embodiment, in step one, the powder transfer device includes a base, on which a transfer component for transferring powder to a base fabric is provided, and on which a negative pressure component for adsorbing powder is provided.

[0015] As a preferred embodiment, the transfer component is configured with a needle-shaped nozzle to transfer the adhesive powder onto the base fabric in a dot matrix pattern.

[0016] As a preferred embodiment, the transfer assembly is configured as a transfer roller.

[0017] As a preferred embodiment, the transfer roller has several transfer grooves, and the base is fixedly provided with a support seat, a motor fixedly provided on the support seat, a connecting shaft fixedly provided on the transfer roller, a hopper fixedly provided on the support seat, and a discharge port opened at the bottom of the hopper. The transfer roller is configured as a hollow structure, and the bottom of the hopper is in contact with the transfer roller.

[0018] As a preferred embodiment, the transfer roller is further provided with a vibration assembly, which includes a fixed shaft fixedly mounted on a support base, a fixed roller fixedly mounted on the fixed shaft, and a plurality of protrusions fixedly mounted on the fixed roller. The protrusions cooperate with the transfer groove, and the connecting shaft is rotatably engaged with the fixed shaft.

[0019] As a preferred embodiment, the negative pressure assembly includes a negative pressure box fixedly mounted on the base and a plurality of negative pressure holes formed on the negative pressure box.

[0020] As a preferred embodiment, the surface of the negative pressure box is made of stainless steel.

[0021] As a preferred embodiment, arc-shaped baffles are fixedly provided on both sides of the hopper, and the inner wall of the arc-shaped baffles is in contact with the outer wall of the transfer roller.

[0022] As a preferred embodiment, in step two, the preheating box temperature is set at 120℃-130℃, and in step five, the heating box temperature is set at 150℃-160℃.

[0023] The beneficial effects of this invention are as follows:

[0024] 1. This invention is equipped with a transfer component and a vibration component. The transfer roller quantitatively and precisely transfers the adhesive powder onto the base fabric. At the same time, the vibration of the transfer groove ensures that the adhesive powder falls fully into it. When the adhesive powder falls onto the base fabric, it can prevent adhesive powder residue in the transfer groove. By preheating the powder clumps and bonding them to the base fabric, and then sprinkling powder and heating them again, the peel strength and washability of the base fabric are improved, and the phenomenon of adhesive seepage from the reverse side of the lining is reduced.

[0025] In summary, this invention has the advantages of high powdering efficiency and good effect, and is suitable for the field of base fabric production technology. Attached Figure Description

Detailed Implementation

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0038] Example 1

[0039] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0040] like Figure 1 As shown, a solid transfer high-peelability base fabric production process includes the following steps:

[0041] Step 1, Transfer Process: The powder clumps are quantitatively transferred onto the base fabric using a powder clump transfer device;

[0042] Step 2, Preheating process: The base fabric is placed in the preheating box for preheating, so that the powder initially melts and adheres to the base fabric;

[0043] Step 3, Powdering process: Apply adhesive powder to the dough using a powdering machine, so that new adhesive powder adheres to the surface of the molten dough;

[0044] Step 4, Powder blowing and suction process: Excess adhesive powder on the base fabric is absorbed by the blowing and suction device;

[0045] Step 5, Heating Process: The adhesive powder is baked again in a heating box to bond it to the base fabric;

[0046] Step 6, Cooling process: The fused base fabric is cooled and shaped by cooling rollers.

[0047] It is worth mentioning that, such as Figures 2 to 9 As shown, in step one, the powder transfer device includes a base 1, a transfer component for transferring powder to the base fabric is provided on the base 1, and a negative pressure component 4 for adsorbing powder is provided on the base 1.

[0048] It is worth mentioning that, such as Figure 2 As shown, the transfer component is configured with a needle-shaped nozzle to transfer adhesive powder onto the base fabric in a dot matrix pattern.

[0049] In addition, such as Figure 2 As shown, the transfer component is set as transfer roller 2.

[0050] In addition, such as Figure 9As shown, the transfer roller 2 has several transfer grooves 21. The base 1 is fixedly equipped with a support seat 22, a motor 23 fixedly mounted on the support seat 22, a connecting shaft 24 fixedly mounted on the transfer roller 2, a hopper 25 fixedly mounted on the support seat 22, and a discharge port 26 at the bottom of the hopper 25. The transfer roller 2 is a hollow structure, and the bottom of the hopper 25 is in close contact with the transfer roller 2. Adhesive powder is placed inside the hopper 25. Both the output shaft of the motor 23 and the connecting shaft 24 are equipped with pulleys, and belts are mounted on the pulleys. In use, when the base fabric passes through the transfer roller 2, the motor 23 drives the transfer roller 2 to rotate. When the transfer groove 21 passes through the discharge port 26, the adhesive powder falls into it from the discharge port 26. Then the transfer roller 2 continues to rotate until it rotates to the surface of the base fabric, where the adhesive powder falls from the transfer groove 21 and forms an adhesive powder ball on the base fabric. Then it enters the preheating box for preheating, so that the outer edge of the powder ball reaches a certain melting point and directly bonds with the base fabric.

[0051] It needs to be emphasized that, such as Figure 8 and Figure 9 As shown, the transfer roller 2 is also equipped with a vibration component 3. The vibration component 3 includes a fixed shaft 31 fixedly mounted on the support base 22, a fixed roller 32 fixedly mounted on the fixed shaft 31, and several protrusions 33 fixedly mounted on the fixed roller 32. The protrusions 33 cooperate with the transfer groove 21, and the connecting shaft 24 is rotatably engaged with the fixed shaft 31. During use, when the transfer roller 2 rotates, the transfer groove 21 will pass through the protrusions 33 and make a small-amplitude impact with the protrusions 33 to achieve the vibration effect. This makes the adhesive powder more compacted when it falls from the hopper 25 into the transfer groove 21, and the adhesive powder can fill the transfer groove 21. In addition, when the adhesive powder falls from the transfer groove 21 onto the base fabric, the vibration can make the adhesive powder fall completely, preventing the adhesive powder from remaining in the transfer groove 21, which would cause the powder clumps to be of different sizes and reduce the powder spreading effect.

[0052] It should be further explained that, such as Figure 9 As shown, the negative pressure assembly 4 includes a negative pressure box 41 fixedly mounted on the base 1 and several negative pressure holes 42 opened on the negative pressure box 41. In use, when the base fabric is transferred on the surface of the negative pressure box 41, after the adhesive powder is transferred to the base fabric, the negative pressure holes 42 adsorb the powder clumps through the base fabric to prevent the powder clumps from dispersing during the transfer, which would result in poor subsequent preheating effect. After the adhesive powder enters the preheating box through the negative pressure box 41 and is preheated, the base fabric is coated with powder by a powder coating machine. The powder coating machine is an existing mature technology and will not be explained in detail here. After the powder coating machine finishes coating, the new adhesive powder falls on the molten adhesive powder, and the two form a certain adhesion. Then, the excess adhesive powder is adsorbed by the suction hood. After that, the final heating is carried out in the heating box to make the adhesive powder fully melt and adhere to the base fabric. Finally, it is cooled and shaped.

[0053] Furthermore, such as Figure 9As shown, the surface of the negative pressure box 41 is made of stainless steel. When the base cloth is transferred on its surface, it can prevent wear and reduce friction without affecting adsorption.

[0054] It is worth mentioning that, such as Figure 6 As shown, arc-shaped baffles 5 are fixedly installed on both sides of the hopper 25, and the inner wall of the arc-shaped baffles 5 is in contact with the outer wall of the transfer roller 2 to prevent the adhesive powder from falling off before it lands on the base fabric.

[0055] Furthermore, such as Figure 1 As shown, in step two, the preheating box temperature is set at 120℃-130℃, and in step five, the heating box temperature is set at 150℃-160℃. The preheating box allows the hot melt adhesive on the surface of the base fabric to initially melt, making it adhesive. The heating box allows the adhesive powder and the base fabric to fully fuse.

[0056] Work process

[0057] As the base fabric passes through the transfer roller 2, the motor 23 drives the transfer roller 2 to rotate. When the transfer trough 21 passes through the discharge port 26, the adhesive powder falls into it from the discharge port 26. The transfer trough 21 passes through the protrusions 33, and the adhesive powder makes a small impact with the protrusions 33, achieving a vibration effect. This makes the adhesive powder more compacted when it falls from the hopper 25 into the transfer trough 21, and the adhesive powder can fill the transfer trough 21 to form powder clumps. Then the transfer roller 2 continues to rotate until it rotates to the surface of the base fabric. The adhesive powder falls from the transfer trough 21 into the base fabric. When the adhesive powder falls from the transfer trough 21 onto the base fabric, the vibration ensures that the adhesive powder falls completely, preventing adhesive powder from remaining in the transfer trough 21 and causing the powder clumps to be of different sizes. First, reduce the powdering effect, then enter the preheating box for preheating, so that the outer edge of the adhesive powder reaches a certain melting point and directly forms a certain bond with the base fabric. During this process, the base fabric is transferred on the surface of the negative pressure box 41. After the adhesive powder is transferred to the base fabric, the negative pressure hole 42 adsorbs the powder clump through the base fabric. After the adhesive powder enters the preheating box through the negative pressure box 41 and is preheated, the base fabric is powdered by the powdering machine. After the powdering machine finishes, the new adhesive powder falls on the molten adhesive powder, and the two form a certain bond. Then, the excess adhesive powder is removed by the blowing and suction device. After that, the final heating is carried out in the heating box to make the adhesive powder fully melt and bond to the base fabric. Finally, it is cooled and shaped.
