[0002] In today's society, with the progress of technology, the emergence of cars has gradually become a means of transportation for every household to travel. Car seats are an important part of cars and are seats for passengers when riding. Car seats can be divided into separate seats and long seats according to their shapes, fixed, detachable, and adjustable seats according to their functions, and single-seat, double-seat, and multi-seat chairs according to the number of passengers.

[0003] Currently, in the existing technology, car seat covers are an important part of car seats. During the processing of car seat covers, it is usually necessary to cut the raw materials of the seat covers. Since the seat fabric itself has excellent wear resistance and anti-slip layers, when the traditional cutting knife cuts the fabric, the fabric is not tightened. When the cutting knife slides, the friction between the cutting knife and the fabric is insufficient, and the fabric will move with the movement of the cutting knife, resulting in many burrs on the edge of the cut fabric.

[0004] Therefore, the utility model provides a fabric cutting device for car seat covers. Summary of the Utility Model

[0005] Therefore, the technical problem to be solved by the utility model is to overcome the situation in the prior art that the seat fabric itself has excellent wear resistance and anti-slip layers, when the traditional cutting knife cuts the fabric, the fabric is not tightened, when the cutting knife slides, the friction between the cutting knife and the fabric is insufficient, and the fabric will move with the movement of the cutting knife, resulting in many burrs on the edge of the cut fabric.

[0006] To solve the above technical problem, the utility model provides a fabric cutting device for car seat covers, including a lapping support platform and a support frame arranged on the outer surface of the lapping support platform, a moving track detachably installed on both side surfaces of the lapping support platform, drums detachably installed on both side surfaces of the lapping support platform, a seat fabric movably sleeved on the outer surface of the drum, and a cushion plate movably sleeved on the outer surface of the lapping support platform; a hydraulic push rod is fixedly installed on the inner side wall surface of the top of the support frame, and an extrusion positioning plate is arranged on the outer surface of the bottom of the hydraulic push rod; a slider is movably sleeved on the inner side wall surface of the moving track, a hydraulic rod is fixedly installed on the top surface of the slider, a positioning table plate is fixedly connected to the output end of the hydraulic rod, a pressing table plate is fixedly installed on the outer surface of the hydraulic rod, and anti-slip soft plates are fixedly connected to the inner side wall surfaces of the pressing table plate and the positioning table plate.

[0007] In an embodiment of the present utility model, a lower pressing plate is fixedly connected to the output end of the hydraulic push rod, and a cutting knife that is movably sleeved on the inner side wall surface of the cutting groove is fixedly connected to the outer surface of the lower pressing plate.

[0008] In an embodiment of the present utility model, an elastic wire is fixedly connected to the bottom surface of the lower pressing plate.

[0009] In an embodiment of the present utility model, one end of the elastic wire is fixedly connected to the outer surface of the top of the extrusion positioning plate, and the outer surface of the extrusion positioning plate is movably sleeved on the inner side wall surface of the cutting knife.

[0010] In an embodiment of the present utility model, limiting rods that are movably sleeved on the outer surface of the lower pressing plate are fixedly connected to the top surface of the extrusion positioning plate and at positions on both sides of the edge.

[0011] In an embodiment of the present utility model, an anti-slip strip that is movably attached to the outer surface of the seat cloth is fixedly connected to the bottom surface of the extrusion positioning plate.

[0012] In an embodiment of the present utility model, a cutting groove is provided at the junction of the cushion table plate and the overlapping support table, and recessed grooves are provided on both side surfaces of the overlapping support table.

[0013] In an embodiment of the present utility model, an arc-shaped support bar is fixedly connected to the bottom surface of the overlapping support table, and one side surface of the cushion table plate is fixedly connected to the top surface of the arc-shaped support bar.

[0014] The above technical solution of the present utility model has the following advantages compared with the prior art:

[0015] For the fabric cutting device of a seat cover of the present utility model, while cooperating with the hydraulic rod to lower the positioning table plate, the two side edge positions of the seat cloth are firmly attached and clamped. Then, by cooperating with the anti-slip soft plates on the inner side walls of the positioning table plate and the lower pressing table plate, the friction and anti-slip force between the seat cloth surface are increased. At this time, the slider is slid and pulled through the moving track, so that the sliders on both side surfaces of the overlapping support table are pulled and moved outwards at the same time, thereby tightening the seat cloth on the top surface of the overlapping support table. Then, it is cut by the cutting knife, achieving the effect that when the surface of the seat cloth under tension contacts the cutting knife, it will not be deformed due to the extrusion of the cutting knife, and thus it is more convenient for the cutting knife to cut the seat cloth.

[0016] A fabric cutting device for a seat cover of the present utility model pulls and extracts the seat fabric wound around the outer surface of a reel, so that it is smoothly laid on the top surface of a lapping support table. At this time, the hydraulic push rod is used to lower the extrusion positioning plate, so that the extrusion positioning plate closely fits the seat fabric on the smooth cushion plate surface, and then the position of the seat fabric is limited, achieving the effect of using the extrusion positioning plate to reduce slight wrinkles or stacking of the seat fabric and increasing the integrity of the seat fabric.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following further describes the present utility model in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and can implement it, but the embodiments cited do not limit the present utility model.

[0025] Refer to Figures 1 to 5As shown in the figure, a fabric cutting device for a seat cover of the present utility model includes a lapping support table 11 and a support frame 12 disposed on the outer surface of the lapping support table 11, a moving track 13 detachably installed on both side surfaces of the lapping support table 11, a reel 115 detachably installed on both side surfaces of the lapping support table 11, a seat cloth 116 movably sleeved on the outer surface of the reel 115, and a cushion table board 112 movably sleeved on the outer surface of the lapping support table 11; a hydraulic push rod 121 is fixedly installed on the inner wall surface of the top of the support frame 12, and an extrusion positioning plate 126 is disposed on the outer surface of the bottom of the hydraulic push rod 121; a slider 131 is movably sleeved on the inner wall surface of the moving track 13, a hydraulic rod 132 is fixedly installed on the top surface of the slider 131, a positioning table board 134 is fixedly connected to the output end of the hydraulic rod 132, a pressing table board 133 is fixedly installed on the outer surface of the hydraulic rod 132, and an anti-slip soft board 135 is fixedly connected to the inner wall surfaces of the pressing table board 133 and the positioning table board 134.

[0026] During operation, the seat cloth 116 wound around the outer surface of the reel 115 is pulled out, so that the seat cloth 116 is smoothly laid on the top surface of the lapping support table 11. At this time, the hydraulic push rod 121 is used to lower the extrusion positioning plate 126, so that the extrusion positioning plate 126 tightly adheres the seat cloth 116 to the smooth surface of the cushion table board 112, thereby performing a position-limiting process on the seat cloth 116, achieving the effect of using the extrusion positioning plate 126 to reduce slight wrinkles or stacking of the seat cloth 116 and increasing the integrity of the seat cloth 116; at the same time, the hydraulic rod 132 is used to lower the positioning table board 134 to firmly clamp and adhere to both side edge positions of the seat cloth 116, and the anti-slip soft board 135 on the inner wall surfaces of the positioning table board 134 and the pressing table board 133 is used to increase the friction and anti-slip force between the seat cloth 116 surfaces. At this time, the slider 131 is slid and pulled through the moving track 13, so that the sliders 131 on both side surfaces of the lapping support table 11 are simultaneously pulled and moved outwards, thereby tightening the seat cloth 116 on the top surface of the lapping support table 11, and then cutting with a cutting knife, achieving the effect that when the surface of the seat cloth 116 under tension contacts the cutting knife, it will not be deformed due to the extrusion of the cutting knife, thereby making it more convenient for the cutting knife to cut the seat cloth 116, avoiding that the seat fabric itself has excellent wear resistance and anti-slip layer. When the traditional cutting knife cuts the fabric, the fabric is not tightened, and when the cutting knife slides, the friction between the cutting knife and the fabric is insufficient, and the fabric will move with the movement of the cutting knife, resulting in many burrs on the edge of the cut fabric.

[0027] Further, as Figures 1 to 5As shown in the figure, a lower pressing plate 122 is fixedly connected to the output end of the hydraulic push rod 121. A cutting knife 123 that is movably sleeved on the inner wall surface of the cutting groove 113 is fixedly connected to the outer surface of the lower pressing plate 122. An elastic wire 124 is fixedly connected to the bottom surface of the lower pressing plate 122. One end of the elastic wire 124 is fixedly connected to the outer surface of the top of the extrusion positioning plate 126, and the outer surface of the extrusion positioning plate 126 is movably sleeved on the inner wall surface of the cutting knife 123. Limiting rods 125 that are movably sleeved on the outer surface of the lower pressing plate 122 are fixedly connected to the top surface of the extrusion positioning plate 126 and are located at the positions of the two side edges. An anti-slip strip 127 that is movably attached to the outer surface of the seat cloth 116 is fixedly connected to the bottom surface of the extrusion positioning plate 126. A cutting groove 113 is formed at the connection between the cushion table plate 112 and the overlapping support table 11. Recessed grooves 114 are formed on the two side surfaces of the overlapping support table 11. An arc-shaped support bar 111 is fixedly connected to the bottom surface of the overlapping support table 11. One side surface of the cushion table plate 112 is fixedly connected to the top surface of the arc-shaped support bar 111.

[0028] During operation, the hydraulic push rod 121 is used to lower the lower pressing plate 122, so that the extrusion positioning plate 126 and the anti-slip strip 127 on the bottom surface are closely attached to the surface of the seat cloth 116 to limit the position of the seat cloth 116. After the extrusion positioning plate 126 completely limits the seat cloth 116, as the hydraulic push rod 121 continues to descend, the limiting rods 125 on the top surface of the extrusion positioning plate 126 slide and pull on the surface of the lower pressing plate 122. As the cutting knife 123 on the outer surface of the lower pressing plate 122 continues to descend, the cutting knife 123 will squeeze the seat cloth 116 on the top surface of the overlapping support table 11. As the surface of the cutting knife 123 passes through the inside of the cutting groove 113, the seat cloth 116 is squeezed and cut by the staggered docking and squeezing between the cutting knife 123 and the gap of the cutting groove 113. Then, the hydraulic push rod 121 is used to retract the lower pressing plate 122, and the elastic wire 124 on the inner wall surface of the top of the lower pressing plate 122 is used to elastically push the extrusion positioning plate 126, so that the cut seat cloth 116 is squeezed and pushed out from inside the cutting knife 123.

[0029] Working principle: The lower pressing plate 122 is lowered in cooperation with the hydraulic push rod 121, so that the extrusion positioning plate 126 and the anti-slip strip 127 on the bottom surface are closely attached to the surface of the seat cloth 116, and the position of the seat cloth 116 is limited. When the extrusion positioning plate 126 completely limits the seat cloth 116, as the hydraulic push rod 121 continues to descend, the limit rod 125 on the top surface of the extrusion positioning plate 126 is pulled and slid on the surface of the lower pressing plate 122, and as the cutting knife 123 on the outer surface of the lower pressing plate 122 continues to descend, the cutting knife 123 is cut. The cutting knife 123 will squeeze the seat cloth 116 on the top surface of the overlapping support platform 11. As the surface of the cutting knife 123 passes through the inside of the cutting groove 113, the seat cloth 116 is squeezed and cut by the interlaced butt extrusion between the cutting knife 123 and the gap of the cutting groove 113. Then, the lower pressing plate 122 is recovered by the hydraulic push rod 121, and the extrusion positioning plate 126 is pushed by the elastic wire 124 on the top inner wall of the lower pressing plate 122, so that the cut seat cloth 116 is squeezed and pushed out from the inside of the cutting knife 123.

[0030] The seat cloth 116 wound on the outer surface of the reel 115 is pulled and removed so that 16 is laid flat on the top surface of the overlapped support platform 11. At this time, the extrusion positioning plate 126 is lowered in cooperation with the hydraulic push rod 121 so that the extrusion positioning plate 126 can tightly fit the seat cloth 116 on the flat surface of the pad plate 112, thereby limiting the position of the seat cloth 116, so as to achieve the effect of using the extrusion positioning plate 126 to reduce slight wrinkles or stacking of the seat cloth 116 and increase the integrity of the seat cloth 116; at the same time, the positioning plate 134 is lowered in cooperation with the hydraulic rod 132 to firmly position the edge positions of both sides of the seat cloth 116 The seat cloth 116 is fitted and clamped, and the anti-skid soft plate 135 on the inner wall of the positioning table 134 and the pressing table 133 is used to increase the friction and anti-skid force between the surface of the seat cloth 116 and the surface. At this time, the slider 131 is slid and pulled by the moving track 13, so that the sliders 131 on the two side surfaces of the overlapping support platform 11 are pulled outward at the same time, thereby tightening the seat cloth 116 on the top surface of the overlapping support platform 11, and then cutting it with a cutting knife, so that the surface of the seat cloth 116 under tension will not be deformed due to the extrusion of the cutting knife when it contacts the cutting knife, thereby making it easier for the cutting knife to cut the seat cloth 116.

[0031] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
