Description

Technical Field

[0001] The invention relates to the technical field of automobile seat cover processing, in particular to a manufacturing process of an automobile seat cover. Background Art

[0002] The car seat cover is a layer of skin covering the foam, frame and other mechanisms on the surface of the car seat, and is an important part of the car seat. Its main functions include: providing comfort; protecting the seat; improving aesthetics; and facilitating cleaning.

[0003] In addition, car seat covers also have the characteristics of personalized customization, with various styles and colors, which can meet the personalized needs of consumers and make the car environment more personalized and unique. At the same time, some seat covers also have functions such as moisture absorption and breathability, which can improve the car environment and maintain a comfortable riding experience.

[0004] In terms of material, car seat covers are divided into genuine leather, artificial leather, fabric, etc. Among them, genuine leather is mainly made of cowhide, which is durable, elastic and easy to clean; artificial leather is a plastic product that feels like leather and has a lower cost; fabric has the characteristics of good air permeability and strong moisture absorption.

[0005] For automobile seat covers made of artificial leather plastic products, cutting and splicing processes are often required. If the surface of the artificial leather is embossed before cutting, the integrity of the embossed pattern cannot be guaranteed after cutting. For example, an internal and external shaping processing device for automobile seat covers described in application number CN202322682669.0 realizes shaping of the bushing in the mold by compression molding, which provides an effective reference for embossing of automobile seat covers, that is, the embossed leather after cutting can be embossed to ensure the integrity of the embossed pattern. However, its processing method is single and the processing efficiency is low, and it is impossible to realize efficient assembly line processing of the workpiece, and it is inconvenient to separate the mold and the workpiece.

[0006] Based on the retrieval of the above information, a production process for automobile seat covers is proposed, which can not only realize the efficient embossing of artificial leather materials in an assembly line manner, but also realize the convenient separation between the artificial leather materials and the mold after embossing, provide convenient conditions for the sorting and stacking of the mold and the embossed artificial leather materials, and effectively improve the production efficiency of automobile seat covers.

[0024] The present invention is further configured as follows: the embossing treatment of the embossing component in step 2 includes:

[0025] A1. After the artificial leather material sheet is heated and softened, the embossing lower die carrying the softened artificial leather material sheet continues to be transported to the bottom of the embossing upper die, and the reducer driving part is turned off;

[0026] A2. Start the hydraulic telescopic rod, which extends and drives the linkage plate to lower the embossing upper die. During the process, the linkage plate drives the double-sided tooth plate to descend, and the double-sided tooth plate drives two gears to rotate. The two gears drive a single-sided tooth plate to rise respectively, and the four single-sided tooth plates drive the supporting plate to rise. The supporting plate drives the ejector rod to rise, and the ejector rod drives the positioning rod to pass through the interval and enter the cup-shaped blind hole. When the positioning rod contacts the top of the inner cavity of the cup-shaped blind hole, the top of the ejector rod contacts the bottom of the embossing lower die. As the supporting plate continues to rise, the ejector rod lifts the embossing lower die, so that the embossing lower die is separated from the upper material cavity, until the embossing upper die enters the embossing lower die to press and emboss the softened artificial leather material sheet;

[0027] A3. When the linkage plate descends, it drives the trigger plate to descend. During the embossing process, the trigger plate descends and squeezes the second trigger button. The second trigger button controls the reducer drive to start, transports the unloading cavity adjacent to the loading cavity to the bottom of the embossing upper die, and closes the reducer drive.

[0028] A4. After the embossing is completed, the hydraulic telescopic rod is controlled to retract and reset. During the process, the embossing lower die carrying the embossed artificial leather material sheet is pulled down by gravity and falls on the top of the four L-shaped functional plates on both sides of the inner cavity of the blanking cavity, wherein the four through holes of the embossing lower die are respectively sleeved on the protrusions on the four L-shaped functional plates;

[0029] A5. When the hydraulic telescopic rod is completely reset, the trigger plate contacts and squeezes the first trigger button, and the first trigger button controls the reducer drive to start, transporting the embossing lower die carrying the unembossed artificial leather material sheet to just below the embossing upper die, and closing the reducer drive;

[0030] A6. Repeat operations A2-A5 to emboss the softened artificial leather material sheet.

[0031] In order to facilitate the separation of the artificial leather material sheet and the embossing lower die after embossing and provide convenient conditions for the reuse of the embossing lower die, the present invention is further configured as follows: the self-swinging traction assembly includes a mounting seat, one side of the top of the mounting seat is fixedly connected to an L-shaped protective plate, the top of the inner cavity of the L-shaped protective plate is fixedly connected to a square plate, the bottom of one side of the square plate is fixedly connected to a guide rod, one side of the L-shaped protective plate is fixedly connected to an extension plate, the front sides of the extension plate and the L-shaped protective plate are penetrated and slidably installed with a plurality of guide rods, one end of a plurality of the guide rods is commonly fixedly connected to a right-angled trapezoidal plate, one end of a plurality of the guide rods is fixedly connected to a limiting plate, the outer periphery of the guide rods and the front and rear sides of the extension plate are sleeved with buffer rings, and the inclined surface of the right-angled trapezoidal plate is inlaid and fixed with a magnetic strip;

[0032] A material discharge hole is provided on both the front and rear sides of the bottom of one side of the embossing lower die, a material discharge trough connected to the material discharge hole is provided on both the front and rear sides of the embossing lower die, the inner surface of the material discharge hole is used in conjunction with the outer surface of the guide rod, the inner surface of the material discharge trough is used in conjunction with the outer surface of the square plate, and the magnetic strip is attracted and matched with the bottom of the embossing lower die;

[0033] The stacking preparation bin is fixedly connected to the top of the mounting seat and is arranged on the outer periphery of the right-angle trapezoidal plate, and the stacking preparation bin is arranged on one side of the L-shaped protective plate. The mold separation track member is fixedly connected between the L-shaped protective plate and the mounting seat, and the mold separation track member is arranged directly below the square plate.

[0034] The present invention is further configured as follows: the method in which the embossing lower die automatically swings in step 3 to guide the embossed artificial leather material sheet to the stacking preparation bin comprises:

[0035] As the high temperature resistant conveyor belt is conveyed, the embossing lower die carrying the completed embossed artificial leather material sheet falling on the L-shaped functional plate moves toward the self-swinging traction assembly. During the process, the material discharge hole of the embossing lower die is sleeved on the outer periphery of the guide rod. As the high temperature resistant conveyor belt continues to convey, the embossing lower die begins to separate from the L-shaped functional plate. When the embossing lower die is completely separated from the L-shaped functional plate, it is pulled by the gravity of the embossing lower die and rotates around the axis of the guide rod. At this time, the opening of the embossing lower die faces downward, and the completed embossed artificial leather material sheet carried therein falls into the stacking preparation bin.

[0036] Among them, after the embossing lower die rotates to a set angle, it collides with the right-angled trapezoidal plate, and the right-angled trapezoidal plate squeezes the buffer ring. After collision buffering, the magnetic strip magnetically adsorbs the bottom of the embossing lower die.

[0037] The present invention is further configured as follows: the manner in which the embossing lower die falls into the die separation track member in step three comprises:

[0038] As the high temperature resistant conveyor belt continues to work, the embossed artificial leather material sheet that is subsequently completed falls to the embossing lower die in the stacking preparation bin to squeeze the previous embossing lower die, so that the previous embossing lower die moves to the L-shaped protective plate. During the process, the material discharge chute is sleeved on the square plate. When the material discharge chute is completely on the square plate, the embossing lower die falls into the mold separation track.

[0039] The present invention provides a manufacturing process for a car seat cover, which has the following beneficial effects:

[0040] (1) The present invention uses an embossing lower die to store artificial leather material sheets, and cooperates with the arrangement of a dual-channel conveying component and a preheating component. During the process of conveying the embossing lower die, the artificial leather material sheets are heated and softened, which facilitates the subsequent embossing operation of the embossing component. During the embossing process, the dual-channel conveying component can also be operated to increase the conveying speed of the embossing lower die. The embossing lower die after embossing is guided by the self-swinging traction component to achieve automatic separation of the artificial leather material sheet and the embossing lower die after embossing. With the operation of the dual-channel conveying component, the embossing lower die can also be collected and utilized, which not only provides efficient guarantee for the embossing processing of the artificial leather material sheets, but also provides convenient conditions for the stacking and storage of the artificial leather material sheets after embossing.

[0041] (2) The present invention constructs a feeding cavity and a unloading cavity through an L-shaped functional plate, utilizes the feeding cavity to realize the positioning and stable conveying of the embossing lower die, utilizes the L-shaped functional plates on both sides of the lower die cavity to support the embossing lower die after embossing, and cooperates with the setting of the protrusion and the through hole to realize stable support for the embossing lower die, and provides reliable support for the subsequent plug-in cooperation of the guide rod and the unloading hole, so as to facilitate the separation of the embossed artificial leather material sheet and the embossing lower die.

[0042] (3) The present invention cooperates with an inverted U-shaped bracket, a linkage plate, a double-sided tooth plate, a gear, a single-sided tooth plate and a support plate. When the linkage plate descends, the support plate can be synchronously raised. With the arrangement of the spacing gap, the embossing upper die, the push rod, the positioning rod and the cup-shaped blind hole, the embossing lower die carrying the artificial leather material sheet can be lifted up to facilitate the embossing operation of the artificial leather material sheet. At the same time, with the cooperation of the trigger plate, the first trigger button and the second trigger button, the reducer drive component is opened and closed to ensure the harmonious unity of the embossing operation and the embossing lower die conveying operation.

[0043] (4) The present invention uses the deadweight of the embossing lower die to realize rotation by setting a feeding hole and a guide rod, thereby facilitating the feeding of artificial leather material sheets after embossing. In conjunction with the setting of a stacking preparation bin, the separated artificial leather material sheets are collected to facilitate stacking and storage. At the same time, the feeding trough and the square plate are set to realize automatic separation of the embossing lower die, so that the embossing lower die can be reused.

[0044] (5) The present invention manufactures a cover sample according to the automobile seat, cuts the artificial leather to obtain the corresponding artificial leather material sheet, and embosses the artificial leather material sheet to ensure the integrity of the embossed pattern, thereby providing a more exquisite guarantee for the appearance of the cover.

[0081] Embodiment 2: This embodiment is an improvement on the previous embodiment. It is a process for manufacturing a car seat cover, and further includes an L-shaped protective plate 39, one side of which is fixedly connected to an extension plate 42. The front sides of the extension plate 42 and the L-shaped protective plate 39 are penetrated and slidably installed with a plurality of guide rods 43. One ends of the plurality of guide rods 43 are commonly fixedly connected to a right-angled trapezoidal plate 44. A stacking preparation bin 6 is arranged on the outer periphery of the right-angled trapezoidal plate 44. One ends of the plurality of guide rods 43 are fixedly connected to a limiting plate 45. The outer periphery of the guide rods 43 and the front and rear sides of the extension plate 42 are both sleeved with buffer rings 46. The inclined surface of the right-angled trapezoidal plate 44 is inlaid with a magnetic strip 47, and the magnetic strip 47 is attracted and matched with the bottom of the embossing lower mold 1.

[0082] The inclination angle of the inclined surface of the right-angle trapezoidal plate 44 is the same as the inclination angle of the bottom of the embossing lower die 1 in a stationary state. The adsorption of the magnetic strip 47 can improve the stability of the embossing lower die 1 during the movement along the guide rod 41. The embossing lower die 1 that rotates excessively around the axis of the guide rod 41 can be limited by the arrangement of the guide rod 43, the buffer ring 46 and the limiting plate 45, thereby improving the separation efficiency of the embossed artificial leather material sheet contained therein.

[0083] After such setting, in step three of embodiment one, when the embossing lower die 1 rotates around the axis of the guide rod 41, after the embossing lower die 1 rotates to a set angle, which is the angle between the embossing lower die 1 when it is transported on the high temperature resistant conveyor belt 10 and the embossing lower die 1 when it is stationary on the guide rod 41, it collides with the right-angled trapezoidal plate 44, and the right-angled trapezoidal plate 44 squeezes the buffer ring 46. After collision buffering, the magnetic strip 47 magnetically adsorbs the bottom of the embossing lower die 1.

[0084] The advantage of the second embodiment over the first embodiment is that the separation efficiency of the embossed artificial leather material sheet and the embossing lower die 1 can be improved, and the stability of the embossing lower die 1 moving on the guide rod 41 can be ensured.

[0085] In summary, the present invention ensures the integrity of the embossed pattern when the artificial leather material sheets are subsequently spliced ​​to the automobile seat cover by cutting first and then embossing, and realizes the efficient output of the embossed artificial leather material sheets in an assembly line processing manner, and can realize the automatic separation of the artificial leather material sheets and the embossing lower mold 1, which provides convenience for the stacking and storage of the artificial leather material sheets after embossing, and can also realize the automatic falling of the embossing lower mold 1 to the mold separation track part 7, providing reliable support for the reuse of the embossing lower mold 1. While being easy to use, the output of the embossed artificial leather material sheets is more efficient.
