Description

Technical Field

[0001] The present disclosure relates to the technical field of automobile seat manufacturing, and in particular to an efficient cutting structure for stacked automobile seat fabrics. Background Art

[0002] In order to facilitate the cleaning of car seats, seat covers are usually placed on the seat surface. In order to increase the comfort of passengers, the fabric of the seat cover is usually made of fluffy and breathable materials with thick texture. The ordinary cutting method can only cut single sheets, and the cutting efficiency is low. Some manufacturers have also noticed this problem.

[0003] For example, Chinese patent document CN217104468U discloses a cloth cutting device for producing automobile seat covers, which includes a workbench, and limiting structures are provided on both sides of the length direction of the top of the workbench; a screw structure is provided on one side of the width direction of the workbench, and a support column is provided on the screw structure, and a rotating block is connected to the support column through a fixing bolt, and a support plate is connected to the side of the rotating block close to the workbench, and a cutting structure is slidably connected to the support plate. By loosening the fixing bolt, the rotating block is rotated on the support column, and the rotating block drives the support plate to rotate. At this time, the support plate forms a certain angle with the top surface of the workbench, and then the cutting structure is started to achieve the effect of cutting the cloth on the workbench, thereby achieving the purpose of oblique cutting of the cloth.

[0004] However, the design of the above-mentioned cloth cutting device for producing the automobile seat cover has the following problems:

[0005] The above-mentioned fabric cutting device for the production of automobile seat covers can stack multiple fabrics on a workbench and cut the multiple fabrics at one time through a cutting structure. However, since the fabric of the seat cover is fluffy, the cutting structure is likely to cause compression and deformation of the fabric when it contacts the surface of the fabric, causing deviations in the cuts of each fabric, resulting in low cutting accuracy and poor flatness of the cut surface. Utility Model Content

[0006] The purpose of the present invention is to overcome the deficiencies in the prior art and provide an efficient cutting structure for stacked automobile seat fabrics with high cutting accuracy and good incision flatness.

[0007] The purpose of this disclosure is achieved through the following technical solutions:

[0008] An efficient cutting structure for stacked car seat fabrics, comprising a stacked fabric assembly, a cutting knife and a pressing head;

[0009] The cutting knife is convexly arranged on the pressing head, the pressing head is used to press the stacked fabric component, and the cutting knife is used to cut the stacked fabric component;

[0010] The stacked fabric assembly includes an oil paper film, multiple fabric pieces and a bottom perforated paper stacked in sequence; the oil paper film is arranged facing the cutting knife, and the bottom perforated paper is provided with a plurality of ventilation holes, and the bottom perforated paper is used to abut against the workbench; the pressing head is also provided with a plurality of suction holes at one end close to the cutting knife, and each of the suction holes is arranged toward the stacked fabric assembly.

[0011] In one embodiment, the pressing head includes a pressing plane, the suction hole is arranged on the pressing plane, one end of the cutting knife is embedded in the pressing plane, and the other end of the cutting knife extends out of the pressing plane, and the pressing plane is used to fit and press the stacked fabric assembly.

[0012] In one embodiment, the oil paper film includes a smooth oil film surface and a rough cover surface;

[0013] The smooth oil film is arranged facing the cutting knife, and the rough covering surface covers and abuts against the uppermost fabric sheet among the plurality of fabric sheets.

[0014] In one embodiment, each of the fabric sheets comprises a skin layer, a foam layer and a fabric layer;

[0015] Between two adjacent fabric pieces, the fabric layer of the fabric piece located at the upper layer abuts against the surface layer of the fabric piece located at the lower layer.

[0016] In one of the embodiments, in the stacked fabric assembly, the surface layer of the fabric sheet located at the uppermost layer is used to abut against the oil paper film.

[0017] In one embodiment, the surface layer is provided with a plurality of anti-slip diagonal lines.

[0018] In one embodiment, a plurality of the suction holes are arranged around the cutting knife at intervals.

[0019] In one embodiment, a plurality of ventilation holes are arranged in a matrix and spaced apart on the bottom perforated paper.

[0020] In one embodiment, a peripheral edge of each fabric piece is provided with a registration notch, and the positions of the registration notches of each fabric piece correspond to each other.

[0021] In one embodiment, the alignment cut is U-shaped or sawtooth-shaped.

[0022] Compared with the prior art, the present invention has at least the following advantages:

[0023] 1) Because the stacked fabric assembly includes sequentially arranged oil paper films, multiple stacked fabric pieces and bottom perforated paper, during the cutting operation, the pressing head presses the stacked fabric assembly, and by setting the oil paper film toward the cutting knife, the cutting knife first passes through the oil paper film and then penetrates into the stacked fabric assembly. The oil paper film is highly flexible and easy to penetrate, which can shorten the time for the cutting knife to penetrate multiple fabric pieces, thereby reducing the deformation of the fabric pieces.

[0024] 2) Because the pressing head is provided with a plurality of suction holes at one end close to the cutting knife, and each suction hole is directed toward the stacked fabric assembly, negative pressure suction can be performed on the fabric pieces through the suction holes. The suction effect of the suction holes enables the fabric pieces to be quickly restored after deformation, thereby effectively alleviating the problem of low cutting accuracy caused by the deformation of the fabric pieces, and ultimately improving the flatness of the cut surface.

[0025] 3) Because there are several ventilation holes on the bottom perforated paper, when the stacked fabric assembly is placed on the workbench, the bottom perforated paper abuts against the workbench, so that the stacked fabric assembly and the workbench can maintain a certain degree of air permeability. When the suction hole sucks the stacked fabric assembly, the outside air can enter the fabric piece through the ventilation holes, and flow out to the suction hole through the incision made by the cutting knife on the oil paper film, so as to form an air flow passage, which is convenient for the suction hole to perform suction and accelerates the restoration of the deformation of the fabric piece.

DETAILED DESCRIPTION

[0035] In order to facilitate the understanding of the present disclosure, the present disclosure will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present disclosure are given in the drawings. However, the present disclosure can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present disclosure more thoroughly and comprehensively understood.

[0036] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present disclosure. The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0038] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0039] like Figure 1 and Figure 2 As shown, an efficient cutting structure 10 for stacked car seat fabrics of one embodiment includes a stacked fabric assembly 100, a cutting knife 200 and a pressing head 300; the cutting knife 200 is convexly arranged on the pressing head 300, the pressing head 300 is used to press the stacked fabric assembly 100, and the cutting knife 200 is used to cut the stacked fabric assembly 100; the stacked fabric assembly 100 includes an oil paper film 110, a plurality of fabric pieces and a bottom perforated paper 130 which are sequentially stacked; the oil paper film 110 is arranged facing the cutting knife 200, and a plurality of ventilation holes 1310 are provided on the bottom perforated paper 130, and the bottom perforated paper 130 is used to abut against the workbench 201; the pressing head 300 is also provided with a plurality of suction holes 3110 at one end close to the cutting knife 200, and each suction hole 3110 is arranged toward the stacked fabric assembly 100.

[0040] It can be understood that because the stacked fabric assembly 100 includes the sequentially arranged oil paper film 110, multiple superimposed fabric pieces 120 and the bottom punched paper 130, during the cutting operation, the pressing head 300 presses the stacked fabric assembly 100, and by setting the oil paper film 110 toward the cutting knife 200, the cutting knife 200 first passes through the oil paper film 110 and then penetrates into the stacked fabric assembly 100. The oil paper film 110 is highly flexible and easy to penetrate, which can shorten the time for the cutting knife 200 to penetrate multiple fabric pieces, thereby reducing the deformation of the fabric piece 120.

[0041] It can be understood that because the pressing head 300 is also provided with a plurality of suction holes 3110 at one end close to the cutting knife 200, and each suction hole 3110 is oriented toward the stacked fabric assembly 100, negative pressure suction can be performed on the fabric piece 120 through the suction holes 3110. Through the suction effect of the suction holes 3110, the fabric piece 120 can be quickly restored after deformation, thereby effectively alleviating the problem of low cutting accuracy caused by the deformation of the fabric piece 120, and ultimately improving the flatness of the cut surface.

[0042] Understandably, combined Figure 2 As shown, because a plurality of ventilation holes 1310 are provided on the bottom punched paper 130, when the stacked fabric assembly 100 is placed on the workbench 201, the bottom punched paper 130 abuts against the workbench 201, so that the stacked fabric assembly 100 and the workbench 201 can maintain a certain degree of air permeability. When the suction hole 3110 sucks the stacked fabric assembly 100, outside air can enter the fabric piece 120 through the ventilation holes 1310, and flow out to the suction holes 3110 through the incision made by the cutting knife 200 on the oil paper film 110, so as to form an air flow passage, which is convenient for the suction hole 3110 to perform suction and accelerate the restoration of the deformation of the fabric piece 120.

[0043] Combination Figure 2 and Figure 3 As shown, in one embodiment, a plurality of ventilation holes 1310 are arranged in a matrix at intervals on the bottom punched paper 130. It can be understood that by arranging a plurality of ventilation holes 1310 in a matrix on the bottom punched paper 130, the ventilation holes 1310 can be evenly distributed on the bottom punched paper 130 as a whole, so that the ventilation effect of each part of the bottom punched paper 130 is the same. When the stacked fabric assembly 100 is placed on the workbench 201, the bottom punched paper 130 is located at the bottom layer of the stacked fabric assembly 100 and abuts against the table surface of the workbench 201. The ventilation holes 1310 arranged in the matrix can keep the air permeability of the stacked fabric assembly 100 and the table surface of the workbench 201 at various positions good, which is convenient for the plurality of suction holes to perform suction operations.

[0044] Combination Figure 1 As shown, in one embodiment, the pressing head 300 includes a pressing plane 310, a suction hole 3110 is provided on the pressing plane 310, one end of the cutting knife 200 is embedded in the pressing plane 310, and the other end of the cutting knife 200 extends out of the pressing plane 310, and the pressing plane 310 is used to fit and press the stacked fabric assembly 100. It can be understood that by embedding one end of the cutting knife 200 in the pressing plane 310, a tightly connected structure is formed between the cutting knife 200 and the pressing plane 310, which is not easy to loosen, and can overcome resistance when cutting the stacked fabric assembly 100, ensuring a smooth cutting process. A pressing plane 310 extends from the other end of the cutting knife 200. When the pressing plane 310 is pressed against the stacked fabric assembly 100, the cutting knife 200 simultaneously penetrates into the stacked fabric assembly 100. The pressing plane 310 can fit well with the stacked fabric assembly 100. Because the suction hole 3110 is arranged on the pressing plane 310, the suction hole 3110 can be closer to the stacked fabric assembly 100, thereby improving the suction effect of the suction hole 3110 and further accelerating the restoration of the fabric piece 120 after deformation.

[0045] Furthermore, combined with Figure 4 and Figure 5 As shown, a plurality of suction holes 3110 are arranged at intervals around the cutting knife 200. It can be understood that by arranging the suction holes 3110 around the cutting knife 200, when the cutting knife 200 penetrates into the stacked fabric assembly 100, the suction holes 3110 suck the stacked fabric assembly 100, and the stacked fabric assembly 100 moves closer to the pressing head 300 under the action of the suction force, so that the cutting knife 200 can penetrate deeper into the stacked fabric assembly 100, making the subsequent cutting operation more convenient.

[0046] Combination Figure 1As shown, in one embodiment, the oil paper film 110 includes a smooth oil film surface 1110 and a rough covering surface 1120; the smooth oil film surface 1110 is arranged toward the cutting knife 200, and the rough covering surface 1120 covers and abuts against the fabric piece 120 located at the top of the multiple fabric pieces. It can be understood that by arranging the smooth oil film surface 1110 of the oil paper film 110 toward the cutting knife 200, when the cutting knife 200 pierces into the stacked fabric assembly 100, the pressing head 300 will abut and press against the smooth oil film surface 1110 of the oil paper film 110, and the friction coefficient between the smooth oil film surface 1110 and the pressing head 300 is small, so that the pressing head 300 is less likely to cause the stacked fabric assembly 100 to move during the cutting movement, thereby avoiding the generation of cutting errors. At the same time, by placing the rough covering surface 1120 on the topmost fabric piece 120 among the multiple fabric pieces, the friction between the oil paper film 110 and the topmost fabric piece 120 among the multiple fabric pieces can be increased, thereby reducing the relative displacement between the oil paper film 110 and the fabric piece 120 during the cutting process of the cutting knife 200, thereby further avoiding the occurrence of cutting errors.

[0047] Combination Figure 6 and Figure 7 As shown, in one embodiment, each fabric piece 120 includes an epidermis layer 1210, a foam layer 1220 and a fabric layer 1230; between two adjacent fabric pieces 120, the fabric layer 1230 of the fabric piece 120 located at the upper layer abuts against the epidermis layer 1210 of the fabric piece 120 located at the lower layer. It can be understood that the epidermis layer 1210 of the fabric piece 120 is used to contact with the passenger, which is relatively smooth and comfortable, and the fabric layer 1230 of the fabric piece 120 is formed by interweaving a number of yarns, which is used to make the foam of the foam layer 1220 more compact and not easy to fall apart during use. By abutting the fabric layer 1230 of the fabric piece 120 located at the upper layer against the epidermis layer 1210 of the fabric piece 120 located at the lower layer, the friction between the two adjacent fabric pieces 120 can be increased, and relative displacement between the fabric pieces 120 during the cutting process of the stacked fabric assembly 100 can be avoided, thereby improving the precision of cutting. Furthermore, a plurality of anti-skid twills 1211 are provided on the epidermis 1210. It can be understood that by providing the anti-skid twills 1211 on the epidermis 1210, a certain angle exists between the twill structure and the length and width directions of the fabric piece 120, which can increase the friction between two adjacent fabric pieces 120 in the length or width direction, and further prevent the two adjacent fabric pieces 120 from slipping.

[0048] Combination Figure 1 and Figure 7As shown, in one embodiment, in the stacked fabric assembly 100, the epidermis 1210 of the fabric piece 120 located at the top layer is used to abut against the oil paper film 110. It can be understood that by using the epidermis 1210 of the fabric piece 120 located at the top layer to abut against the oil paper film 110, the friction between the fabric piece 120 located at the top layer and the oil paper film 110 can be increased by the abutment between the epidermis 1210 and the oil paper film 110, and the relative displacement between the oil paper film 110 and the fabric piece 120 during the cutting process of the cutting knife 200 can be reduced, and the generation of cutting errors can be further avoided.

[0049] Combination Figure 6 As shown, in one embodiment, each fabric piece 120 is provided with a positioning notch 1240 on its periphery, and the positions of the positioning notches 1240 of each fabric piece 120 correspond to each other. It can be understood that by providing the positioning notches 1240 on the periphery of each fabric piece 120, the positions of the positioning notches 1240 of each fabric piece 120 correspond to each other, and when multiple fabric pieces are stacked, it is more convenient to align the positions. At the same time, when two adjacent fabric pieces 120 slide relative to each other, the operator can observe the offset of the positioning notches 1240 at the corresponding positions of the two adjacent fabric pieces 120, and timely discover and align the positions of the positioning notches 1240, so as to ensure that the two adjacent fabric pieces 120 are accurately stacked, and further improve the cutting accuracy. Specifically, the positioning notch 1240 is U-shaped or sawtooth-shaped. It can be understood that by setting the alignment notch 1240 to be U-shaped, the U-shaped structure has an arc position, which makes it easier to observe the position offset between two adjacent fabric pieces 120, and the alignment is also more accurate. Alternatively, by setting the alignment notch 1240 to be zigzag, the zigzag structure has many teeth, which can make alignment easier.

[0050] Compared with the prior art, the present invention has at least the following advantages:

[0051] 1) Because the stacked fabric assembly 100 includes the sequentially arranged oil paper film 110, multiple stacked fabric pieces 120 and the bottom punched paper 130, during the cutting operation, the pressing head 300 presses the stacked fabric assembly 100, and by setting the oil paper film 110 toward the cutting knife 200, the cutting knife 200 first passes through the oil paper film 110 and then penetrates into the stacked fabric assembly 100. The oil paper film 110 is highly flexible and easy to penetrate, which can shorten the time for the cutting knife 200 to penetrate multiple fabric pieces, thereby reducing the deformation of the fabric piece 120.

[0052] 2) Because the pressing head 300 is also provided with a plurality of suction holes 3110 at one end close to the cutting knife 200, and each suction hole 3110 is oriented toward the stacked fabric assembly 100, negative pressure suction can be performed on the fabric piece 120 through the suction holes 3110. Through the suction effect of the suction holes 3110, the fabric piece 120 can be quickly restored after deformation, thereby effectively alleviating the problem of low cutting accuracy caused by the deformation of the fabric piece 120, and ultimately improving the flatness of the cut surface.

[0053] 3) Because a plurality of ventilation holes 1310 are provided on the bottom punched paper 130, when the stacked fabric assembly 100 is placed on the workbench 201, the bottom punched paper 130 abuts against the workbench 201, so that the stacked fabric assembly 100 and the workbench 201 can maintain a certain degree of air permeability. When the suction hole 3110 sucks the stacked fabric assembly 100, outside air can enter the fabric piece 120 through the ventilation holes 1310, and flow out to the suction holes 3110 through the incision made by the cutting knife 200 on the oil paper film 110, so as to form an air flow passage, which is convenient for the suction hole 3110 to perform suction and accelerate the restoration of the deformation of the fabric piece 120.

[0054] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the patent of the present disclosure shall be based on the attached claims.
