Description

Technical Field

[0001] This invention belongs to the technical field of equipment for sofa manufacturing, and particularly relates to a fabric dryer for sofa manufacturing. Background Technology

[0002] The fabrics used in sofa manufacturing mainly include linen, cotton, velvet, blended fabrics, and leather. Before being used on a sofa frame, these fabrics generally need to undergo the following steps: washing, drying, cutting, and hemming. The drying step requires a fabric dryer.

[0003] Common fabric drying equipment mainly consists of: unwinding roller, winding roller, drying hood, and upper and lower air outlets, ultimately achieving a relatively efficient top-to-bottom drying effect for the fabric.

[0004] Furthermore, integrated dehydration and drying equipment with even better drying effects has emerged on the market, which first physically removes moisture and then dries it with hot air. This not only improves the drying degree of the fabric but also greatly reduces the power consumption of the hot air structure.

[0005] For example, Chinese utility model patent with patent publication number CN220269966U and publication date of December 29, 2023, discloses a sofa fabric drying device, which includes: a base plate, a drying box fixedly connected above the base plate, a baffle curtain provided at the inlet and outlet of the drying box, a motor fixedly connected above the drying box, a dryer fixedly connected to the output end of the motor, a drying plate fixedly connected to the output end of the dryer, air ducts fixedly connected to both sides below the drying plate, an air plate fixedly connected to the opposite side of the air ducts, an adsorption device provided above the base plate, support plates fixedly connected to both sides above the base plate, and a vibrating plate fixedly connected to the output end of a vibrating motor.

[0006] The fabric drying equipment in this utility model patent has the following structure, principle and advantages: Through the drying plate, air duct, air plate and adsorption device, it can adsorb some fabrics with strong adsorption force to avoid excessive water content and thus affect the drying effect. At the same time, it dries the top and bottom surfaces of the fabric to accelerate the drying speed of the fabric.

[0007] However, in actual use, this sofa fabric drying equipment still has at least the following shortcomings, which is also the technical problem that this invention aims to solve:

[0008] The water removal methods resulting from its adsorption and vibration effects are both active water removal. The adsorption and vibration devices require independent electrical systems such as motors and exhaust fans, which is very troublesome and costly.

[0009] Therefore, in summary, there is an urgent need for a new type of energy-saving fabric dryer with a prior passive dehydration effect for drying and dehydrating various types of sofa fabrics. Summary of the Invention

[0010] This invention provides a fabric dryer for sofa manufacturing. By assembling a hot air pipe, an upper hot air plate, a horizontal shaft, a rotating upper plate unit, a combined stud unit, a lifting lower plate unit, and an arc-shaped scraper unit on the drying hood, the fabric can receive a sufficient, suitable, stable, and adjustable passive scraping operation before the hot air drying operation, ensuring sufficient drying and water removal intensity with relatively low hot air power.

[0011] The technical solution adopted by the present invention to solve the above problems is: a fabric dryer for sofa manufacturing, the structure of which includes a drying hood, a hot air pipe, and an upper hot air plate, and further includes a transverse shaft disposed on the upper hot air plate, a rotating upper plate unit sleeved on the transverse shaft and used to abut against the fabric, a combined stud unit disposed on the rotating upper plate unit and used to abut against the inner top surface of the drying hood, a lifting lower plate unit disposed on the combined stud unit and used to abut against the fabric, and two arc-shaped squeegee units respectively disposed on the opposite sides of the rotating upper plate unit and the lifting lower plate unit and used to clamp the fabric.

[0012] A further preferred technical solution is that the rotating upper plate unit includes a horizontal tube sleeved on the horizontal shaft, an upper plate disposed on the horizontal tube, and a screw hole disposed on the upper plate for mounting the combined stud unit.

[0013] A further preferred technical solution is that the combined stud unit includes a stud screwed into the screw hole and the lifting lower plate unit, and an internally threaded tube disposed at the upper end of the stud and used to fix the upper plate in an inclined state by abutting against the inner top surface of the drying hood.

[0014] A further preferred technical solution is that the combined stud unit further includes an elastic anti-slip block disposed at the upper end of the internally threaded tube.

[0015] A further preferred technical solution is that the lifting lower plate unit includes a lower plate for abutting against the lower surface of the fabric, and a threaded groove disposed on the lower plate for inserting the stud.

[0016] A further preferred technical solution is that the arc-shaped wiper unit includes an arc-shaped straight plate disposed on the opposite side of the upper plate or the lower plate and used to abut against the fabric.

[0017] A further preferred technical solution is that the arc-shaped wiper unit further includes two L-shaped straight plates disposed on the inner ring surface of the arc-shaped straight plate and used to clamp the upper plate or the lower plate.

[0018] A further preferred technical solution is that the length of the L-shaped straight plate is greater than that of the arc-shaped straight plate, and the arc-shaped wiper unit further includes an arc-shaped cut at the end of the L-shaped straight plate for engaging the stud.

[0019] A further preferred technical solution is that the arc-shaped wiper unit further includes an arc-shaped end plate disposed on the arc-shaped straight plate and used for water blocking.

[0020] A further preferred technical solution is that a bottom plate drainage groove is also provided below the drying hood. Attached Figure Description

[0034] The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0035] As attached Figure 1-8 As shown, a fabric dryer for sofa manufacturing includes a drying hood 11, a hot air pipe 12, and an upper hot air plate 13. It also includes a transverse shaft 1 disposed on the upper hot air plate 13, a rotating upper plate unit 2 sleeved on the transverse shaft 1 and used to abut against the fabric a, a combined stud unit 3 disposed on the rotating upper plate unit 2 and used to abut against the inner top surface of the drying hood 11, a lifting lower plate unit 4 disposed on the combined stud unit 3 and used to abut against the fabric a, and two arc-shaped squeegee units 5 respectively disposed on the opposite sides of the rotating upper plate unit 2 and the lifting lower plate unit 4 and used to clamp the fabric a.

[0036] In this embodiment, the base plate 16 is also provided with an unwinding roller and a take-up roller located on both sides of the drying hood 11. Thus, the fabric a starts from the unwinding roller, passes through the arc-shaped squeegee unit 5, the upper and lower hot air plates, and finally reaches the take-up roller, completing the entire hot air drying operation.

[0037] The drying hood 11 is in the shape of an inverted U, and the hot air flows in the following order: hot air pipe 12, upper hot air plate 13, connecting air pipe 14, and lower hot air plate 15, ultimately forming a relatively efficient upper and lower combined hot air drying effect on fabric a.

[0038] The transverse shaft 1, the rotating upper plate unit 2, the combined stud unit 3, and the lifting lower plate unit 4 form a passive clamping dehydration structure before the aforementioned hot air drying structure. The advantages of this dehydration structure include at least the elimination of active energy-consuming equipment such as motors and fans, requiring only a slight increase in the winding strength of the take-up rollers. Fabric dryers incorporating this passive dehydration structure, like existing common exhaust-type and / or vibration-type active dehydration-drying machines, can significantly reduce the power consumption required by the hot air blower.

[0039] Finally, the arc-shaped wiper unit 5 has the direct function of covering the "relatively sharp" edges of the rotating upper plate unit 2 and the lifting lower plate unit 4. Its ultimate function is to prevent the aforementioned edges from pressing marks on the fabric a, and to prevent the fabric a from experiencing significant shedding, cracking, delamination, tearing, or other accidents.

[0040] The rotating upper plate unit 2 includes a horizontal tube 201 sleeved on the horizontal shaft 1, an upper plate 202 disposed on the horizontal tube 201, and a screw hole 203 disposed on the upper plate 202 for mounting the combined stud unit 3.

[0041] In this embodiment, the transverse shaft 1 is a round shaft and the transverse tube 201 is a round tube. The two are at least interlocked, and screw connection is optional. This allows the water squeezing gap formed between the rotating upper plate unit 2 and the lifting lower plate unit 4 to be tilted with one end higher and the other lower, ensuring that the squeezed water can quickly gather, flow down, and separate from the fabric.

[0042] The upper plate 202 is rectangular in shape, with its bottom edge closer to the unwinding roller than its top edge. The upper plate 202 is installed at an angle to distribute the impact force of the fabric on it as much as possible along the horizontal axis 1, thus preventing the connection between the horizontal tube 201 and the upper plate 202 from breaking easily.

[0043] The combined stud unit 3 includes a stud 301 screwed into the screw hole 203 and the lifting lower plate unit 4, and an internally threaded tube 302 located at the upper end of the stud 301 and used to fix the upper plate 202 in an inclined state by abutting against the inner top surface of the drying hood 11.

[0044] In this embodiment, fabric a is horizontal on both the unwinding and take-up rollers, and also needs to be as horizontal as possible between the upper hot air plate 13 and the lower hot air plate 15 to prevent fabric a from being "scorched" due to being too close to the hot air nozzles. Therefore, the inclination of the inclined gap between the rotating upper plate unit 2 and the lifting lower plate unit 4 for rapid drainage needs to be sufficient and appropriate. It can be inclined as much as possible under the premise of safe hot air drying operation, and the maximum suitable drying temperature is also different for different fabrics.

[0045] Therefore, the aforementioned "tilted gap" needs to be adjusted in terms of tilt. This is achieved by having two combined stud units 3 extend from the upper plate 202 in two different sizes, one long and one short, so that the tilt angle of the aforementioned squeezing gap can be adjusted as needed, and once adjusted, it is not easy to change again.

[0046] Finally, there are two methods for adjusting the protrusion dimensions of the two combined stud units 3, namely:

[0047] First, the stud 301 itself has different protrusion dimensions on the screw hole 203;

[0048] Secondly, even if the protrusion dimensions of the two studs 301 are the same, they can be adjusted by unscrewing the internal threaded tube 302.

[0049] The combined stud unit 3 also includes an elastic anti-slip block 303 disposed at the upper end of the internal threaded tube 302.

[0050] In this embodiment, the main bodies of the drying hood 11, the rotating upper plate unit 2, the combined stud unit 3, and the lifting lower plate unit 4 are all made of stainless steel, while the elastic anti-slip block 303 is made of ordinary rubber, ensuring that when the internal threaded tube 302 is pressed against the inner top surface of the drying hood 11, it is not easy to slip or be squeezed and deformed against each other.

[0051] The lifting lower plate unit 4 includes a lower plate 401 for abutting against the lower surface of fabric a, and a threaded groove 402 disposed on the lower plate 401 for inserting the stud 301.

[0052] In this embodiment, the width of the water-squeezing gap formed between the lower plate 401 and the upper plate 202 is predetermined and kept stationary during the connection of the studs 301. Then, by screwing in two studs 301, the width of the gap is guaranteed to remain unchanged. Of course, this is on the premise that the studs 301 do not loosen or fall off.

[0053] Therefore, the first function of the internally threaded tube 302 is as described above: to fix the inclined state of the squeezing gap, while the second function of the internally threaded tube 302 is: to clamp the stud 301 and prevent it from rotating and loosening spontaneously.

[0054] In other words, the two threaded grooves 402 can have different depths, and the two studs 301 can also have different lengths, as long as the studs 301 do not rotate spontaneously after being screwed in as needed, and the internal threaded tube 302 does not loosen spontaneously after pressing against the inner top surface of the drying cover 11.

[0055] The arc-shaped wiper unit 5 includes an arc-shaped straight plate 501 disposed on the opposite side of the upper plate 202 or the lower plate 401 and used to abut against the fabric a.

[0056] In this embodiment, the arc-shaped straight plate 501 is a portion of a circular tube cut along its length, and the central angle of its arc-shaped cross-section is an obtuse angle, which is sufficient to cover the two edges of the upper plate 202 or the lower plate 401 respectively.

[0057] At this point, fabric a slides over the relatively wide and relatively flat outer ring surface of the curved straight plate 501, which can prevent the edges at the gap between the upper plate 202 and the lower plate 401 from pressing marks on fabric a, and prevent fabric a from shedding a lot of lint due to concentrated scraping.

[0058] The arc-shaped wiper unit 5 also includes two L-shaped straight plates 502 disposed on the inner ring surface of the arc-shaped straight plate 501 and used to clamp the upper plate 202 or the lower plate 401.

[0059] In this embodiment, the arc-shaped straight plate 501 is made of stainless steel, and the L-shaped straight plate 502 is made of ordinary rubber. The latter can greatly improve the installation stability of the arc-shaped straight plate 501 and prevent the arc-shaped straight plate 501 from being rotated and falling off by the moving fabric a.

[0060] The length of the L-shaped straight plate 502 is greater than that of the arc-shaped straight plate 501. The arc-shaped wiper unit 5 also includes an arc-shaped cutout 503 located at the end of the L-shaped straight plate 502 and used to engage the stud 301.

[0061] In this embodiment, the threaded structure on the stud 301 is a protruding threaded segment rather than a recessed threaded groove. This threaded segment can achieve greater clamping strength on the arc-shaped cutout 503, ultimately resulting in:

[0062] The arc-shaped scraper unit 5 is located at the squeezing gap, making it difficult for it to fall off due to circumferential rotation, and also difficult for it to slide laterally and shift.

[0063] Ensure that fabric a is extruded and passes only on the outer ring surface of the completely stationary curved straight plate 501.

[0064] The arc-shaped wiper unit 5 also includes an arc-shaped end plate 504 disposed on the arc-shaped straight plate 501 and used for blocking water.

[0065] In this embodiment, the aforementioned water-squeezing gap is inclined to facilitate rapid drainage. That is, one end of the arc-shaped straight plate 501 is high and the other end is low, while the arc-shaped end plate 504 is set at the lower end. This prevents water squeezed out of the fabric from flowing into the threaded groove 402 and accumulating over a long period of time. Otherwise, dust will accumulate in the threaded groove 402, jamming the stud 301 and making it difficult to unscrew.

[0066] The drying hood 11 is also provided with a bottom plate drainage groove 6.

[0067] In this embodiment, the bottom plate drainage groove 6 includes an inclined bottom surface with at least one open end, which ensures that the water squeezed out from the fabric can be concentrated and quickly discharged in the bottom plate drainage groove 6, so that water does not accumulate on the upper surface of the bottom plate 16 as much as possible.

[0068] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various modifications can be made without departing from the spirit of the present invention. These are non-inventive modifications and are protected by patent law as long as they fall within the scope of the claims of the present invention.
