Description

Technical Field

[0001] The present application relates to the technical field of shaping equipment, and in particular to a sofa fabric drying and shaping device. Background Art

[0002] Sofa fabric refers to the general term for various main coverings used in the sofa manufacturing process, which directly affects the comfort, appearance and durability of the sofa. Among them, common sofa fabric types include cotton fabric, linen fabric, polyester fabric, velvet fabric, leather fabric, blended fabric and other special fabrics.

[0003] Natural fiber fabrics, such as cotton, linen, silk, and velvet, require drying and shaping during processing to stabilize their size and shape and prevent shrinkage or deformation. Drying and shaping is an important step to ensure fabric quality, especially after post-processing such as dyeing and printing.

[0004] Sofa fabrics are typically dried and shaped using shaping equipment. However, during the various front-end production processes of the shaping equipment, impurities from other fabric materials, such as lint and cotton, can easily adhere to the surface of the sofa fabric. If the fabric is directly fed into the shaping equipment for drying and shaping, these impurities will adhere to the surface and be difficult to remove, affecting the quality of the fabric after drying and shaping. Currently available shaping equipment employs a brush roller within the equipment assembly to remove impurities. However, the brush roller only acts on a single, localized area of the fabric, resulting in unsatisfactory cleaning results and requiring improvement. Utility Model Content

[0005] Based on this, the present application provides a sofa fabric drying and shaping device, which can shake the fabric by patting, thereby shaking off the raw material impurities and making them leave the sofa fabric, which is conducive to maintaining good molding quality of the sofa fabric after drying and shaping.

[0006] The present application provides a sofa fabric drying and shaping device that adopts the following technical solutions:

[0007] A sofa fabric drying and shaping device includes a device assembly, wherein a tensioning roller group for tensioning the sofa fabric, a hot air mechanism for drying the fabric, and a flapping mechanism for flapping the fabric are provided inside the device assembly; wherein the flapping mechanism includes a fixed frame fixedly arranged inside the device assembly, a sliding seat movably mounted on the fixing frame, a cam member rotatably mounted on the fixing frame, and a driving component for driving the cam member to rotate, a return spring is provided between the sliding seat and the fixing frame, and the return spring is used to force the sliding seat to normally abut against the cam member; a flapping member is provided on the side of the sliding seat close to the sofa fabric, and when the cam member rotates, the flapping member intermittently flaps the sofa fabric.

[0008] By adopting the above-mentioned technical solution, after the sofa fabric of the present application enters the interior of the device assembly and is tensioned on the tensioning roller group, the fabric can be dried and shaped by the hot air mechanism; during the drying operation, the cam component is driven to rotate by controlling the movement of the driving component. Since the sliding seat is normally abutted against the sliding seat by the return spring, the rotation of the cam component causes the sliding seat to form a reciprocating movement effect. At this time, the beating component can move back and forth and intermittently beat the sofa fabric, causing the sofa fabric to shake and shake off impurities in the raw material, which is beneficial to maintaining good molding quality of the sofa fabric after drying and shaping.

[0009] Optionally, the tensioning roller group includes multiple first tensioning rollers and multiple second tensioning rollers, the first tensioning rollers are spaced apart from each other and are located together above the flapping mechanism, the second tensioning rollers are spaced apart from each other and are located together below the flapping mechanism, and the sofa fabric is alternately wound around the first tensioning rollers and the second tensioning rollers; there are two groups of sliding seats, which are symmetrically arranged on two opposite sides of the fixed frame, and each sliding seat is pressed against the cam component through a return spring.

[0010] By adopting the above technical solution, by setting the first tensioning roller and the second tensioning roller, the sofa fabric can bypass the beating mechanism after being tensioned by the tensioning roller group, and the two sliding seats arranged on the two opposite sides of the fixed frame can be used to beat different sections of the sofa fabric respectively, thereby enhancing the shaking effect of the sofa fabric, being more conducive to shaking off impurities in the raw materials, and ensuring that the sofa fabric maintains good molding quality after drying and shaping.

[0011] Optionally, the cam component includes a base portion and three outer protrusions arranged on the outer circumference of the base portion, the base portion is arranged in a cylindrical shape, and all the outer protrusions are arranged at equal distances around the central axis of the base portion.

[0012] By adopting the above-mentioned technical solution, by setting three outer protrusions, the driving component drives the cam component to rotate, and when one of the cam components abuts against the sliding seat and forces the sliding seat to move outward, the other sliding seat can abut against the remaining two outer protrusions under the elastic force of the return spring, thereby enabling the slapping components on the two sliding seats to alternately slap the fabric, which is also beneficial to enhancing the shaking effect of the sofa fabric and facilitating the shaking off of impurities in the raw materials.

[0013] Optionally, a vertically sliding lifting seat is installed inside the device assembly, and a lightweight roller is rotatably installed on the lifting seat. The lightweight roller is located above the first tensioning roller. When the sofa fabric is wrapped around the tensioning roller group, the lightweight roller is pressed against the sofa fabric under the action of its own gravity.

[0014] By adopting the above technical solution, the lightweight roller can normally be pressed against the sofa fabric under the action of its own gravity. When the flapping mechanism flaps the fabric, the sofa fabric relaxes outward, forcing the lightweight roller to move upward under force, so that the fabric can be quickly reset after shaking, which is conducive to keeping the sofa fabric in a tensioned state and stably conveying it, reducing the occurrence of local wrinkles on the fabric.

[0015] Optionally, a plurality of brush rollers are rotatably installed inside the device assembly, each brush roller is correspondingly arranged on the outside of the first tensioning roller / the second tensioning roller, and a soft brush is provided on the outer peripheral surface of the brush roller.

[0016] By adopting the above technical solution, the setting of the brush roller can assist in brushing off raw material impurities attached to the surface of the sofa fabric, further allowing the sofa fabric to maintain good molding quality after drying and shaping.

[0017] Optionally, an installation chamber is provided on the side of the sliding seat away from the cam component, the flapping component is movably installed inside the installation chamber, and an elastic pad is provided between the flapping component and the inner wall of the installation chamber, the elastic pad is used to normally force the flapping component to move away from the sliding seat.

[0018] By adopting the above-mentioned technical solution, by making the beating component movably connected to the sliding seat, when the cam component rotates to force the sliding seat to move back and forth, the beating component can press against the sofa fabric and force the elastic cushion to undergo elastic deformation. The elastic force generated by the elastic cushion acting on the beating component can further force the sofa fabric to shake, thereby further reducing the possibility of raw material impurities adhering to the surface of the sofa fabric.

[0019] Optionally, a vent is provided at the bottom of the device assembly, and the hot air mechanism includes a fan component fixed on the inside of the vent, a dustproof mesh cover provided on the air inlet end of the vent, and an electric heating pipe fixed on the air outlet end of the vent.

[0020] By adopting the above technical solution, the fan component arranged at the vent can blow air pressure to the sofa fabric. The air pressure increases the temperature after passing through the electric heating tube, and thus the sofa fabric can be dried and shaped smoothly; the dustproof mesh cover can be used to intercept impurities and foreign matter in the outside air, reducing the possibility of impurities and foreign matter entering the inner side of the device assembly through the vent and adhering to the surface of the sofa fabric.

[0021] Optionally, a negative pressure port is provided on the top of the device assembly, and a filter plate is installed on the negative pressure port for intercepting impurities in the raw material; a negative pressure mechanism is provided on the outside of the device assembly and covers the negative pressure port.

[0022] By adopting the above technical solution, by setting a negative pressure port on the other inner wall of the device assembly, the fan component and the negative pressure mechanism outside the negative pressure port can form convection, so that the raw material impurities can adhere to the surface of the filter plate along the wind pressure after leaving the fabric, thereby reducing the raw material impurities from floating arbitrarily inside the device assembly and adhering to the surface of the sofa fabric again.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By setting a driving component to drive the cam component to rotate, it can drive the beating component on the sliding seat to intermittently beat the sofa fabric, causing the sofa fabric to shake and shake off impurities in the raw material, which is conducive to maintaining good molding quality of the sofa fabric after drying and shaping;

[0025] 2. By setting sliding seats on two opposite sides of the fixed frame, the two sliding seats can respectively beat different sections of the sofa fabric, thereby enhancing the shaking effect of the sofa fabric, making it more conducive to shaking off impurities in the raw materials and ensuring that the sofa fabric maintains good molding quality after drying and shaping;

[0026] 3. By setting a lightweight roller so that it is normally pressed against the sofa fabric under the action of its own gravity, the sofa fabric will relax outward when the flapping mechanism flaps the fabric, forcing the lightweight roller to move upward under force, so that the sofa fabric can quickly reset after shaking, which is conducive to keeping the sofa fabric in a tensioned state and stably conveying it, reducing the occurrence of local wrinkles on the sofa fabric.

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The embodiment of the present application discloses a sofa fabric drying and shaping device.

[0034] Reference Figure 1 A sofa fabric drying and shaping device includes a device assembly 1, within which are disposed a tensioning roller group 2 for tensioning the sofa fabric, a hot air mechanism 3 for drying the fabric, and a flapping mechanism 4 for flapping the fabric. The tensioning roller group 2 includes a plurality of first tensioning rollers 21 and a plurality of second tensioning rollers 22, each of which is rotatably connected to the inner wall of the device assembly 1. The first tensioning rollers 21 are arranged at intervals along the length of the device assembly 1, and all of the first tensioning rollers 21 are located above the flapping mechanism 4. The second tensioning rollers 22 are arranged at intervals along the length of the device assembly 1, and all of the tensioning rollers are located below the flapping mechanism 4.

[0035] It should be noted that when the sofa fabric enters the interior of the device assembly 1, the sofa fabric can be alternately wound around the first tensioning roller 21 and the second tensioning roller 22 in sequence; in addition, the two first tensioning rollers 21 located at the front end and the rear end of the fabric conveying are both connected to a rotating motor. By controlling the synchronous operation of the two rotating motors, the sofa fabric can be conveyed forward smoothly.

[0036] A plurality of brush rollers 5 are rotatably installed inside the device assembly 1. The number of brush rollers 5 is set in multiples, and each brush roller 5 is correspondingly arranged on the outside of the first tensioning roller 21 / the second tensioning roller 22; a soft brush 51 is fixedly provided on the outer peripheral surface of the brush roller 5. When the sofa fabric is conveyed forward, the soft brush 51 can assist in removing raw material impurities attached to the sofa fabric, so that the sofa fabric has good molding quality after drying and shaping.

[0037] Reference Figure 2The beating mechanism 4 includes a fixed frame 41, a sliding seat 42, a cam member 43 and a driving component (not shown in the figure). The fixed frame 41 is arranged inside the device assembly 1; there are two sliding seats 42, and the two sliding seats 42 are symmetrically arranged on two opposite sides of the fixed frame 41, and each sliding seat 42 is slidably connected to the fixed frame 41; the sliding connection method of the sliding seat 42 and the fixed frame 41 can be a method in which the slider cooperates with the slide groove, or a method in which the slider cooperates with the slide rail, but it is sufficient as long as the sliding seat 42 can be slidably connected to the fixed frame 41.

[0038] The cam member 43 is rotatably mounted on the fixed frame 41 and is located between the two sliding seats 42. The cam member 43 of this embodiment includes a base portion 431 and a protruding portion 432. The base portion 431 is cylindrical, and the cam member 43 is rotatably connected to the fixed frame 41 via the base portion 431. There are three protruding portions 432, each of which is integrally formed on the outer peripheral surface of the base portion 431, and all protruding portions 432 are equidistantly arranged around the central axis of the base portion 431. In addition, the driving component in this embodiment is configured as a motor. The driving component is fixed to the fixed frame 41, and the output end of the driving component is coaxially connected to the base portion 431. By controlling the operation of the driving component, the cam member 43 can be driven to rotate around its own axis.

[0039] A return spring 45 is provided between the sliding seat 42 and the fixed frame 41, one end of the return spring 45 rests against the inner wall of the fixed frame 41, and the other end rests against the side of the sliding seat 42 away from the cam member 43; the return spring 45 can always act on the elastic force of the sliding seat 42, thereby forcing the sliding seat 42 to rest against the cam member 43 normally; and when the driving component operates to drive the cam member 43 to rotate, the sliding seat 42 can form a reciprocating movement effect, and since there are three outer protrusions 432, when one of the cam members 43 rests against the sliding seat 42 and forces the sliding seat 42 to move, the other sliding seat 42 can rest against the remaining two outer protrusions 432 under the elastic force of the return spring 45, thereby realizing the alternating movement of the two sliding seats 42.

[0040] Reference Figure 3 The side of the sliding seat 42 away from the cam member 43 is provided with multiple installation chambers 421, and the flapping member 44 is movably installed inside the installation chamber 421; the outer side surface of the end of the flapping member 44 is provided with an integrally formed abutting portion 441, the abutting portion 441 is located inside the installation chamber 421, and the inner wall of the port of the installation chamber 421 is provided with an integrally formed limiting portion 422, the internal size of the limiting portion 422 is equal to the external size of the flapping member 44, and the abutment cooperation between the abutting portion 441 and the limiting portion 422 can limit the extreme movement position of the flapping member 44, thereby reducing the occurrence of the flapping member 44 detaching from the sliding seat 42.

[0041] An elastic pad 46 is disposed between the flapping member 44 and the mounting chamber 421 and is bonded to the inner wall of the mounting chamber 421. In this embodiment, the elastic pad 46 is made of a sponge material and constantly exerts an elastic force on the flapping member 44, forcing it to move away from the sliding seat 42. When the drive assembly rotates, driving the cam member 43 and forcing the two sliding seats 42 to move alternately, the flapping member 44 intermittently flaps the sofa fabric, thereby shaking off any impurities adhering to the fabric. Furthermore, the flapping members 44 disposed on different sliding seats 42 can flap different sections of the fabric, further facilitating the removal of impurities.

[0042] Back to Figure 2 The two opposite inner side walls of the device assembly 1 are respectively provided with vertical slide grooves 11, and the vertical slide grooves 11 are matched with lifting seats 61 so that the lifting seats 61 can move up and down inside the vertical slide grooves 11; a lightweight roller 6 is installed between the two lifting seats 61 for common rotation, and the lightweight roller 6 is located above the first tensioning roller 21 and directly above the fixed frame 41.

[0043] In this embodiment, there are specific requirements for the weight of the lightweight roller 6. Specifically, the lightweight roller 6 must be able to press against the sofa fabric under the action of gravity and maintain the sofa fabric in a taut state. Furthermore, the lightweight roller 6 must be not too heavy, so that when the flapping member 44 flaps the sofa fabric, the lightweight roller 6 can be forced upward. This allows the sofa fabric to quickly return to its original position after being shaken, maintaining a taut state and allowing for stable conveyance, thereby reducing the occurrence of local wrinkles in the sofa fabric. The specific weight of the lightweight roller 6 can be determined and selected appropriately through multiple tests during actual production.

[0044] Back to Figure 1 The device assembly 1 is fixed on the ground foundation by the support legs 12, and a vent 13 communicating with the interior is provided at the bottom of the device assembly 1. Figure 4 The hot air mechanism 3 includes a fan component 31, a dustproof net cover 32 and an electric heating pipe 33, wherein the fan component 31 is fixed to the inner side of the vent 13, the dustproof net cover 32 is fixed to the bottom of the device assembly 1 and covers the vent 13, which can reduce the entry of external impurities and foreign matter into the interior when the fan component 31 is operating; there are multiple electric heating pipes 33, each of which is arranged side by side and fixed to the air outlet end of the vent 13, respectively, for heating the wind entering the device assembly 1 to increase the temperature, thereby drying and shaping the sofa fabric.

[0045] Back to Figure 1The bottom of the device assembly 1 is provided with a negative pressure port 14, which is matched with a filter plate 15. In this embodiment, the filter plate 15 has a double-layer structure, and the top of the device assembly 1 is provided with a negative pressure mechanism 7. The negative pressure mechanism 7 includes a negative pressure cover 71 and a negative pressure pipe 72 connected to the negative pressure cover 71. The negative pressure cover 71 is located over the negative pressure port 14. The negative pressure mechanism 7 forms a convection air path with the hot air mechanism 3, allowing impurities in the raw material to float upward after being shaken off and adsorbed on the filter plate 15, thereby reducing the chance of impurities in the raw material adhering to the surface of the sofa fabric again.

[0046] The above are preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
