[0002] Traditional imitation leather raw materials are PVC leather or PU leather. The texture is processed on the imitation leather by means of drum hot pressing, and the texture is delicate and regular.

[0003] The imitation leather needs to maintain a certain thickness to ensure that the drum presses into the imitation leather to a certain depth and the texture remains clear. At the same time, a large amount of glue is added to the imitation leather raw material to ensure that the texture is fixed after hot pressing and does not rebound.

[0004] The relatively thick raw material and a large amount of glue make the imitation leather have a strong plastic smell and glue smell, which affect the user experience.

[0013] A further technical solution is that the scraper forms a cutter head that acts on the roller to scrape off the skin material; a working surface is formed on the scraper along the moving direction of the skin material, and the working surface forms a resistance to act on the accumulation of the skin material.

[0014] A further technical solution is that a undulating member is connected to the scraper, and convex surfaces and concave surfaces that are connected to each other in sequence and at intervals are formed on the undulating member; the skin material accumulates on one side where the convex surface moves in and one side where the concave surface moves in; the skin material unfolds on one side where the convex surface moves out and one side where the concave surface moves out.

[0015] A further technical solution is that the first vibration block rotates close to the position where the convex surface transitions to the concave surface; the convex parts are distributed in a staggered manner.

[0017] A further technical solution is that the second vibration blocks are oppositely arranged on both sides of the artificial leather; a convex plate is arranged at the cooling end of the cooling device; convex blocks with different sizes and heights are arranged in parallel on the convex plate.

[0018] A processing method of an artificial leather texture processing device includes the following steps:

[0019] Step 1: The raw material enters the material tank, and the rolling elements rotate along the rolling frame; the raw material contacts the rolling elements, and the driving wheel coats the raw material on the rolling elements; the heating device heats the raw material to form the skin material;

[0020] Step 2: The cutter head acts on the rolling elements to scrape off the skin material, the skin material contacts and accumulates on the working surface to generate wrinkles; the skin material moves along the undulating member, and the skin material reciprocally accumulates and unfolds on the convex surface and the concave surface to form wrinkles;

[0021] Step 3: The first vibration block vibrates to drive the convex parts to act on the skin material to extrude and form wrinkles;

[0022] Step 4: The skin material and the fabric move between the pressing roller and the reheating device, the pressing roller and the reheating device heat the skin material, and the pressing roller presses the fabric into the skin material.

[0023] Step 5: The second vibrating block vibrates to drive the convex block to contact the leather material, and the cooling end of the cooling device acts on the leather material through the convex block; the leather material shrinks due to cooling to form textures.

[0024] Compared with the prior art, the beneficial technical effects of the present invention are as follows: (1) The raw material is coated on the roller, and the heating device heats both sides of the raw material to form the leather material; the leather material is formed by the method of coating first and then heating, so that the leather material is thinner, which is convenient for the leather material to shrink to form textures; at the same time, due to the thin leather material, the consumption of the raw material is reduced, and the plastic smell of the artificial leather is reduced; the scraper scrapes the leather material on the roller and accumulates to form folds in an inclined direction; the first vibrating block forms a convex part, and the convex part extrudes the leather material to form folds in the left and right directions; the hot pressing mechanism heats the leather material to soften it, and the hot pressing mechanism acts on the fabric and presses the fabric into the bottom surface of the leather material; after the leather material solidifies, the leather material and the fabric are adhered together without using glue for adhesion; the cooling end of the cooling device acts on the leather material, and the leather material shrinks along the vicinity of the folds to form textures; due to the cooling end of the cooling device contacting the leather material frequently and intermittently, the shrinkage rates of different positions of the leather material are different, and irregular textures are formed on the leather material.

[0025] (2) The first elastic device forms an elastic thrust on the groove block, so that the acting wheel can closely fit the rolling body, ensuring uniform thickness after the raw material is extruded, and enabling better control of the shrinkage rates of each position when the leather material shrinks; the tool rest is installed at the driving end of the third driving device, and the third driving device drives the tool rest to move back and forth; the tool head moves back and forth to scrape the leather material at an inclined angle, so that the leather material accumulates in an inclined state on the acting surface to form folds.

[0026] (3) The leather material accumulates on the convex surface moving-in side and the concave surface moving-in side; the leather material unfolds on the convex surface moving-out side and the concave surface moving-out side; the leather material accumulates multiple times on the undulating member to form folds, and the accumulation of the leather material is in the front-back direction; the undulating member is horizontally arranged at the driving end of the second driving device; the second driving device drives the undulating member to move horizontally back and forth, and the leather material on the undulating member is offset in the front-back direction during the moving process, and the leather material forms folds by accumulating in the left-right direction; the front-back movement of the undulating member and the front-back movement of the scraper do not affect each other; at the same time, due to the speed difference between the front-back movement of the undulating member and the front-back movement of the scraper, the leather material is pulled at the contact position of the scraper and the undulating member to form folds in the left-right direction.

[0027] (4) The first vibrating block is installed at the vibrating end of the first vibrating device, and the first vibrating block vibrates and reciprocally contacts the leather material, so that the leather material can smoothly complete the transition from accumulation to unfolding; due to the vibration of the first vibrating block, the convex part presses into and disengages from the leather material reciprocally, and folds in the left and right directions are formed in the leather material during the process of pressing into the leather material; since the leather material will move in the front-back direction, the leather material accumulates after contacting the convex part during the moving process, intensifying the folds of the leather material.

[0028] (5) The side of the leather close to the fabric is heated by a pressing roller and a reheating device, so that the side of the leather close to the fabric is softened by the heat, and the pressing roller and the guide plate contact the fabric to press into the leather; the fabric pulls the leather to avoid excessive wrinkles on the leather, so that the texture formed on the imitation leather is dense.

[0029] (6) By controlling the distance between the second vibration blocks, the upper and lower heights of the leather shrinkage are controlled, and the conditions under which the convex blocks act on the leather are different, so that the texture of the imitation leather is random and closer to the texture of genuine leather.

[0040] Figure 1 The structural schematic diagram of the artificial leather texture processing device according to the first embodiment of the present invention is shown. Figure 2 The top view structure diagram of the roller frame and the rolling element according to the embodiment of the present invention is shown. Figure 3 The front view structure diagram of the scraper according to the embodiment of the present invention is shown. In combination with Figures 1-3 As shown, the present invention discloses an artificial leather texture processing device.

[0041] The artificial leather texture processing device includes: a second vibration block 7, a hot pressing mechanism 6, a scraper 4, a roller 1, a material trough 2 for accommodating raw materials, a heating device 3 located inside and outside the roller 1, and a first vibration block 5 that vibrates and acts on the leather material.

[0042] Among them, the material tank 2 and the scraper 4 are relatively located above the left and right sides of the roller 1. Raw materials are injected into the material tank 2, and the raw materials are removed from the material tank 2 and coated on the roller 1. The heating device 3 heats both sides of the raw materials to form leather materials.

[0043] By forming the leather material in the way of coating first and then heating, the leather material is made thinner, which is convenient for the leather material to shrink and form textures. At the same time, because the leather material is thinner, the consumption of raw materials is reduced, and the plastic smell of artificial leather is reduced.

[0044] The scraper 4 presses against the roller 1, the roller 1 rotates, and the scraper 4 scrapes the leather material on the roller 1 and accumulates to form folds in the inclined direction. The first vibration block 5 forms a convex part 51, and the convex part 51 presses the leather material to form folds in the left and right directions.

[0045] The hot pressing mechanism 6 heats the leather material to soften it, and the hot pressing mechanism 6 acts on the fabric and presses the fabric into the bottom surface of the leather material. After the leather material solidifies, the leather material and the fabric are adhered together, and no glue is needed for adhesion.

[0046] The second vibration block 7 vibrates and acts on the artificial leather. A cooling device 71 is arranged in the second vibration block 7, and the cooling end of the cooling device 71 acts on the leather material. The leather material shrinks along the vicinity of the folds to form textures. Due to the cooling end of the cooling device 71 contacting the leather material frequently and intermittently, the shrinkage rates of different positions of the leather material are different, and irregular textures are formed on the leather material.

[0047] The roller 1 includes: a roller frame 11 arranged in the front-back direction, a rolling body 12 rotatably arranged on the roller frame 11, and a side frame 13 arranged on the roller frame 11. Among them, the heating device 3 is arranged on the roller frame 11 and the side frame 13.

[0048] The roller 1 further includes a first motor 111. The rear end of the rolling body 12 is connected to the driving end of the first motor 111. The side frame 13 is connected to the rear end of the roller frame 11 and extends to the upper end outside the roller 1. Exemplarily, there are two groups of heating devices 3. The heating devices 3 are distributed vertically, and the heating ends of the heating devices 3 face the raw materials. The heating device 3 located above acts on the upper part of the raw materials for heating, and the heating device 3 located below acts on the lower part of the raw materials through the rolling body 12 for heating. The raw materials are completely solidified after being heated from two directions to form leather materials.

[0049] An outlet 21 is formed on one side of the material tank 2 close to the roller 1. A driving wheel 22 is rotatably arranged on the material tank 2 at a position close to the outlet 21, and the driving wheel 22 acts on the roller 1 to coat the raw materials. A gap is formed between the rolling body 12 and the driving wheel 22 so that the raw materials are flattened when passing through.

[0050] At the front and rear ends of the material trough 2, there are sliding groove blocks 211, and at the front and rear ends of the material trough 2, there is a first elastic device 212 that presses against the groove blocks 211. The action wheel 22 is rotatably arranged at the front and rear on the groove blocks 211. Exemplarily, the first elastic device 212 is a spring. The first elastic device 212 forms an elastic thrust on the groove blocks 211, enabling the action wheel 22 to closely fit the rolling body 12, ensuring uniform thickness after the raw material is extruded, and enabling better control of the shrinkage rate at each position when the leather material shrinks.

[0051] The raw material flows out from below the action wheel 22 and contacts the rolling body 12. The raw material enters between the rolling body 12 and the action wheel 22, and the raw material adheres to the rolling body 12.

[0052] The scraper 4 forms a cutter head 41, which acts on the roller 1 to scrape the leather material. On the scraper 4, there is an action surface 42 formed along the moving direction of the leather material, and the action surface 42 forms a resistance acting on the accumulation of the leather material.

[0053] One end of the action surface 42 extends towards the cutter head 41, and the other end of the action surface 42 bends and extends upwards. The scraper 4 is installed on the tool rest 43, and there is a sliding block 44 arranged on the tool rest 43. There is a second elastic device 45 on the tool rest 43. Exemplarily, the second elastic device 45 is a spring. The second elastic device 45 forms an elastic thrust on the block 44, enabling the cutter head 41 to closely fit the rolling body 12 and completely scrape the leather material.

[0054] The tool rest 43 is installed at the driving end of the third driving device 46, and the third driving device 46 drives the tool rest 43 to move back and forth. The cutter head 41 moves back and forth to scrape the leather material at an inclined angle, causing the leather material to accumulate in a folded state on the action surface 42 in an inclined state.

[0055] Figure 4 The front view structure diagram of the first vibration block in the embodiment of the present invention is shown. Figure 5 The bottom view structure diagram of the first vibration block in the embodiment of the present invention is shown. Figure 6 The front view structure diagram of the undulating member in the embodiment of the present invention is shown. Figures 1-6 As shown, an undulating member 8 is connected to the scraper 4, and the right end of the scraper 4 overlaps on the undulating member 8. On the undulating member 8, convex surfaces 81 and concave surfaces 82 that are sequentially spaced and connected to each other in a transitional manner are formed. The convex surfaces 81 and the concave surfaces 82 are formed on the upper surface of the undulating member 8. The leather material moves from left to right along the undulating member 8. The leather material accumulates on the side where the convex surface 81 moves in and the side where the concave surface 82 moves in. The leather material unfolds on the side where the convex surface 81 moves out and the side where the concave surface 82 moves out. The leather material forms folds through multiple accumulations on the undulating member 8, and the accumulation of the leather material is in the front-rear direction.

[0056] The undulating member 8 is horizontally arranged at the driving end of the second driving device 83. The second driving device 83 drives the undulating member 8 to move horizontally back and forth. During the movement of the leather on the undulating member 8, there is an offset in the front-back direction, and the leather forms a pile in the left-right direction to form folds.

[0057] The front-back movement of the undulating member 8 and the front-back movement of the scraper 4 do not affect each other. At the same time, due to the speed difference between the front-back movement of the undulating member 8 and the front-back movement of the scraper 4, the leather is pulled at the contact position between the scraper 4 and the undulating member 8 to form folds in the left-right direction.

[0058] The first vibrating block 5 rotates close to the position where the convex surface 81 transitions to the concave surface 82. Mounting positions 52 are formed side by side around the first vibrating block 5, and the convex portions 51 are arranged side by side on the mounting positions 52. The convex portions 51 on adjacent mounting positions 52 are staggeredly distributed. The two ends of the convex portion 51 transition to the mounting position 52 to form a transition portion 53 to prevent the two ends of the convex portion 51 from scratching the leather.

[0059] The first vibrating block 5 is installed at the vibrating end of the first vibrating device 54. The first vibrating block 5 vibrates and reciprocally contacts the leather, and the leather can smoothly complete the transition from piling up to stretching. Due to the vibration of the first vibrating block 5, the convex portion 51 presses into and disengages from the leather reciprocally. During the process of pressing into the leather, the leather forms folds in the left-right direction. Since the leather will move in the front-back direction, during the movement, the leather accumulates after contacting the convex portion 51, intensifying the folds of the leather.

[0060] A material feeding cylinder 9 is arranged between the undulating member 8 and the hot pressing mechanism 6. The material feeding cylinder 9 is driven by a third motor 91 to rotate. The fabric is wound around the material feeding cylinder 9. The third motor 91 drives the material feeding cylinder 9 to rotate for feeding the material. The fabric is moved in and hung on the pressing roller 61, and the fabric is located below the leather.

[0061] Figure 7 The front view structural diagram of the hot pressing mechanism according to the embodiment of the present invention is shown. In combination Figures 1-7 As shown, the hot pressing mechanism 6 includes pressing rollers 61 arranged side by side, a reheating device 62 for heating the leather, and guide plates 63 swingably arranged on both sides of the reheating device 62. Among them, the pressing rollers 61 and the reheating device 62 heat the leather.

[0062] The pressing rollers 61 are arranged in the front-back direction and are distributed in the left-right direction. The reheating device 62 is arranged in the front-back direction and is distributed in the left-right direction. The reheating device 62 is located below the pressing rollers 61 and is staggeredly distributed.

[0063] After the leather and the fabric reciprocally bend, they are hung on the pressing rollers 61, and the lower ends of the leather and the fabric droop close to the heating end of the reheating device 62.

[0064] The pressure roller 61 and the reheating device 62 are installed on the hot pressing bracket 64. A heating rod 65 is installed on the hot pressing bracket 64 and extends into the pressure roller 61 to heat the pressure roller 61. A second motor 66 is installed on the hot pressing bracket 64 to drive the pressure roller 61 to rotate.

[0065] The pressure roller 61 rotates along the hot pressing bracket 64, heating the leather material and pressing the fabric into the heated surface of the leather material.

[0066] The guide plates 63 swing relatively at the left and right ends of the reheating device 62. When the guide plates 63 swing closer to each other, the guide plates 63 push the falling positions of the leather material and the fabric to narrow. When the leather material and the fabric are in a moving state, the guide plates 63 abut against the fabric and press the fabric into the leather material.

[0067] The side of the leather material close to the fabric is heated by the pressure roller 61 and the reheating device 62, so that the side of the leather material close to the fabric is softened by heat. The pressure roller 61 and the guide plates 63 contact the fabric and press it into the leather material. The fabric pulls on the leather material, preventing the range of wrinkles on the leather material from being too large and making the texture formed on the artificial leather dense.

[0068] Figure 8 The front view structural diagram of the second vibration block in the embodiment of the present invention is shown. In combination Figures 1-8 As shown, the second vibration blocks 7 are arranged oppositely on both sides of the artificial leather. A convex plate 72 is provided at the cooling end of the cooling device 71. Convex blocks 73 of different sizes and heights are arranged in parallel on the convex plate 72. The second vibration blocks 7 are driven to vibrate by a second vibration device 74.

[0069] The larger the convex block 73 is, the larger the contact area between the convex block 73 and the fabric is, the larger the cooled area of the fabric is, and the larger the formation range of the texture is. The smaller the convex block 73 is, the smaller the contact area between the convex block 73 and the fabric is, the smaller the cooled area of the fabric is, and the smaller the formation range of the texture is.

[0070] The higher the convex block 73 is, the deeper the contact depth between the convex block 73 and the fabric is, the deeper the cooled depth of the fabric is, and the deeper the formed depth of the texture is. The lower the convex block 73 is, the shallower the contact depth between the convex block 73 and the fabric is, the shallower the cooled depth of the fabric is, and the shallower the formed depth of the texture is.

[0071] The second vibration block 7 can drive the convex blocks 73 to act on the upper and lower sides of the leather material, causing the upper and lower sides of the leather material to contract simultaneously, making the texture of the artificial leather clear.

[0072] The higher the frequency of the second vibration device 74 driving the second vibration block 7 to vibrate is, the more frequent the convex block 73 contacts the leather material, and the denser the texture of the artificial leather is. The lower the frequency of the second vibration device 74 driving the second vibration block 7 to vibrate is, the less frequent the convex block 73 contacts the leather material, and the sparser the texture of the artificial leather is.

[0073] By controlling the distance between the second vibration blocks 7, the up-and-down height of the leather material shrinkage is controlled. Since the situations where the bump 73 acts on the leather material are different, the patterns formed by the imitation leather texture are random and closer to the patterns of genuine leather.

[0074] Second Embodiment:

[0075] The processing method of the imitation leather texture processing device includes the following steps:

[0076] Step 1: The raw material enters the material tank 2, and the rolling body 12 rotates along the rolling frame 11. The raw material contacts the rolling body 12, and the acting wheel 22 coats the raw material on the rolling body 12. The heating device 3 heats the raw material to form the leather material.

[0077] The first elastic device 212 pushes the acting wheel 22 to contact the rolling body 12. By replacing the first elastic devices 212 with different specifications, the force with which the acting wheel 22 rolls the raw material is different, thereby controlling the thickness of the raw material. According to the thickness of the raw material, the power of the heating device 3 is controlled to make the leather material dry thoroughly.

[0078] The rolling body 12 and the acting wheel 22 control the leather material at a relatively thin thickness in a clamping and rolling manner, making the wrinkles obvious and the texture clear after the leather material is stacked. At the same time, the leather material is relatively thin, and the pulling effect of the fabric on the leather material is obvious, and clear texture can be formed.

[0079] Step 2: The leather material moves along the undulating member 8, and the leather material reciprocally accumulates and unfolds on the convex surface 81 and the concave surface 82 to form wrinkles.

[0080] The third driving device 46 drives the scraper 4 to move back and forth, the cutter head 41 moves back and forth along the rolling body 12, the rolling body 12 rotates itself, and the cutter head 41 acts on the rolling body 12 to scrape off the leather material. During the movement of the cutter head 41, a forward or backward thrust is formed on the leather material, making the leather material contact in an inclined state and form accumulation on the acting surface 42 to generate wrinkles.

[0081] The leather material moves left and right along the undulating member 8, and the leather material moves along the convex surface 81 and the concave surface 82 in sequence. When the leather material moves to the convex surface 81, accumulation is formed on the incoming side, and unfolding is formed on the outgoing side. When the leather material moves to the concave surface 82, accumulation is formed on the incoming side, and unfolding is formed on the outgoing side, and this reciprocates in a cycle.

[0082] During the movement of the leather material, the second driving device 83 drives the undulating member 8 to move back and forth, and the leather material deviates in the front-back direction under the drive of inertia.

[0083] During the movement of the leather material along the undulating member 8, accumulation occurs in the front-back direction, and during the deviation of the leather material, accumulation occurs in the left-right direction, and wrinkles in different directions can be formed on the leather material.

[0084] Step 3: The first vibration block 5 vibrates to drive the convex part 51 to act on the leather material to extrude and form wrinkles.

[0085] The first vibration device 54 drives the first vibration block 5 to vibrate. The vibration of the first vibration block 5 drives the convex part 51 to reciprocate and act on the leather material. The leather material is extruded to form wrinkles in the left - right direction. Due to the forward - backward offset of the leather material, it accumulates when contacting the convex part 51 during the offset process, deepening the wrinkles of the leather material.

[0086] Step 4: The leather material and the fabric move between the pressure roller 61 and the reheating device 62. The upper ends of the leather material and the fabric are hung on the pressure roller 61, and the lower ends of the leather material and the fabric droop and approach the reheating device 62. The pressure roller 61 and the reheating device 62 heat the leather material, and the pressure roller 61 presses the fabric into the leather material. The second motor 66 drives the pressure roller 61 to rotate to drive the leather material and the fabric to move, and at the same time controls the distance between the lower ends of the leather material and the fabric and the reheating device 62 to avoid overheating of the leather material and the fabric. The leather material and the fabric are hung on the pressure roller 61, and the pressure roller 61 presses the fabric into the leather material. When the leather material and the fabric move, they contact the guide plate 63, and the fabric is pressed into the leather material.

[0087] Step 5: The second vibration device 74 drives the second vibration block 7 to vibrate. The second vibration block 7 drives the convex block 73 to contact the leather material. The cooling end of the cooling device 71 acts on the leather material through the convex block 73, and the leather material contracts due to cooling to form textures. By controlling the power of the second vibration device 74, the frequency of the convex block 73 contacting the leather material is adjusted, thereby controlling the density of the artificial leather texture.
