Description

Technical Field

[0001] This utility model relates to the technical field of PVC artificial leather processing equipment, specifically a PVC artificial leather embossing equipment. Background Technology

[0002] PVC artificial leather, also known as polyvinyl chloride artificial leather, is a type of imitation leather composite material made by coating a fabric substrate with chemical raw materials such as PVC resin. It is a major type of artificial leather and is widely used to replace natural leather, especially in cost-sensitive fields where it has a significant cost-performance advantage. In the production process of PVC artificial leather, embossing is a key process that gives the surface of the artificial leather a specific texture and pattern, enhancing its aesthetics and texture.

[0003] According to Chinese Patent Publication No. CN 221740667 U, a PVC artificial leather embossing device is used to solve the technical problem of adjusting the embossing spacing for each type of leather to meet different processing requirements. This avoids wasting costs by having to re-create the embossing mold spacing based on the fabric's embossing control spacing, thus improving processing capacity. The device includes a worktable with a fixed support frame. The support frame includes a top plate and support plates on both sides of the top plate. A processing space exists between the top plate and the worktable. A lifting assembly is installed on the top plate, and two slidable first translational components are mounted on the lifting assembly. Each of the two first translational components has an imprinting component mounted on it. A second translational component for moving the leather is mounted on the worktable, and both imprinting components face the second translational component. This invention has a simple structure and is mainly used for embossing leather.

[0004] In the production process of PVC artificial leather, embossing and winding are two key steps. In the aforementioned production equipment, embossing and winding are usually carried out separately. After the embossing process is completed, the embossed PVC artificial leather needs to be manually transported to the winding equipment for winding. This separate production method has many drawbacks. First, the manual handling process not only consumes a lot of time and manpower and increases labor intensity, but also easily damages the PVC artificial leather during the handling process, affecting product quality. Summary of the Invention

[0005] The purpose of this invention is to provide a PVC artificial leather embossing device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a PVC artificial leather embossing device, including an embossing mechanism, wherein a winding mechanism is provided on the left side of the embossing mechanism; The embossing mechanism includes a bottom frame and a top frame. A hydraulic telescopic rod is fixedly connected to the bottom wall of the bottom frame. A fixing ring is fixedly connected to the top of the hydraulic telescopic rod. A connecting rod is rotatably connected inside the fixing ring. A flattening roller is fixedly connected to the inner side of the connecting rod. Grooves are provided at both the front and rear ends of the bottom frame and the top frame. An electric push rod is installed in the groove. A connecting ring is fixedly connected to the output end of the electric push rod. A support rod is rotatably connected inside the connecting ring. An embossing roller is fixedly connected to the inner side of the support rod. A fixing rod is fixedly connected to the bottom of the top frame.

[0007] Preferably, four hydraulic telescopic rods, fixing rings, and connecting rods are provided, with two of them located at the front and rear ends inside the bottom frame, and the other two located at the front and rear ends inside the top frame.

[0008] Furthermore, there are four hydraulic telescopic rods, four fixing rings, and four connecting rods. Two of these combinations—two hydraulic telescopic rods, two fixing rings, and two connecting rods—are located at the front and rear ends of the bottom frame, respectively. The other two combinations are located at the front and rear ends of the top frame, respectively. This arrangement ensures that there are corresponding structures at the front and rear of both the bottom and top frames to support the leveling rollers, guaranteeing the stability and uniformity of the PVC artificial leather leveling process during operation. It applies force to the artificial leather from multiple positions, avoiding poor leveling results due to uneven local force.

[0009] Preferably, there are four electric push rods, connecting rings and support rods, with two of them located at the front and rear ends inside the bottom frame, and the other two electric push rods, connecting rings and support rods located at the front and rear ends inside the top frame.

[0010] Furthermore, there are four electric push rods, four connecting rings, and four support rods. Two sets of two electric push rods, two connecting rings, and two support rods are respectively located at the front and rear ends inside the bottom frame. The other two sets are respectively located at the front and rear ends inside the top frame. This layout allows the front and rear parts of the bottom and top frames to move up and down via the extension and retraction of the electric push rods, which in turn drive the embossing rollers through the connecting rings and support rods. This enables precise control of the embossing depth of the PVC artificial leather and applies pressure from multiple positions to ensure the uniformity and consistency of the embossing.

[0011] Preferably, guide grooves are provided on the inner walls of the front and rear right sides of the bottom frame and the top frame, and the four fixing rings and connecting rods are respectively located in the guide grooves provided on the inner walls of the front and rear right sides of the bottom frame and the top frame.

[0012] Furthermore, guide grooves are provided on the inner walls of the front and rear ends of the right side of the bottom frame and the top frame. Four fixing rings and connecting rods are located in these guide grooves. The function of the guide grooves is to provide a precise track for the movement of the fixing rings and connecting rods, ensuring that they can only move in a straight line along a specific direction, namely the direction of the guide groove, under the drive of the hydraulic telescopic rod. This ensures the stability and accuracy of the leveling roller during its up-and-down movement, avoiding deviation or shaking, which would affect the leveling effect on the PVC artificial leather.

[0013] Preferably, there are two of each of the leveling roller and the embossing roller, with the two leveling rollers and the two embossing rollers being the top of the inner side of the bottom frame and the bottom of the inner side of the top frame, respectively. There are multiple fixing rods, and the top frame is fixedly connected to the top of the bottom frame through multiple fixing rods fixedly connected to the bottom.

[0014] Furthermore, there are two leveling rollers and two embossing rollers. The two leveling rollers are located at the top inside the bottom frame, and the two embossing rollers are located at the bottom inside the top frame. This layout allows the PVC artificial leather to be leveled by the leveling rollers inside the bottom frame first, removing wrinkles and unevenness from the surface, before passing through the embossing rollers between the top and bottom frames for embossing, ensuring the quality of the embossing. At the same time, multiple fixing rods are provided. The top frame is fixedly connected to the top of the bottom frame through multiple fixing rods fixed to the bottom. The setting of multiple fixing rods enhances the connection strength and stability between the top and bottom frames, ensuring that the top and bottom frames will not shift relative to each other during operation, thereby ensuring the relative positional accuracy between the leveling rollers and the embossing rollers, enabling the equipment to work stably and reliably.

[0015] Preferably, the winding mechanism includes a motor and a first rotating rod. A second rotating rod is fixedly connected to the output end of the motor. A first connecting seat is fixedly connected to the end of the second rotating rod away from the motor. A first semi-circular ring is fixedly connected to the inner side of the first connecting seat. A second semi-circular ring is fixedly connected to the top left and right sides of the first semi-circular ring by bolts. A second connecting seat is fixedly connected to the inner side of the first rotating rod. A third semi-circular ring is fixedly connected to the inner side of the second connecting seat. A fourth semi-circular ring is fixedly connected to the top left and right sides of the third semi-circular ring by bolts. A winding roller is engaged with the top of the first and third semi-circular rings.

[0016] Preferably, the motor is fixedly connected to the front left side of the base frame, the first rotating rod is rotatably connected to the rear left side of the base frame, and the second rotating rod is rotatably connected to the front left side of the base frame.

[0017] Furthermore, the motor is fixedly connected to the front left side of the base frame, providing power to the entire winding mechanism. The first rotating rod is rotatably connected to the rear left side of the base frame, and the second rotating rod is rotatably connected to the front left side of the base frame. The motor output end is fixedly connected to the second rotating rod. When the motor starts, it drives the second rotating rod to rotate, which in turn drives the winding roller to rotate through the first connecting seat, the first semi-circular ring, and the second semi-circular ring, thus realizing the winding operation of the PVC artificial leather. The first rotating rod supports and fixes the other end of the winding roller through the second connecting seat, the third semi-circular ring, and the fourth semi-circular ring, ensuring the stability of the winding roller during rotation. This layout allows the winding mechanism to be organically integrated with the base frame, making reasonable use of space and ensuring the smooth operation of the winding process.

[0018] Compared with the prior art, the beneficial effects achieved by this utility model are: Firstly, this invention, through the setting of hydraulic telescopic rods and electric push rods, can easily adjust the positions of the flattening roller and the embossing roller, thereby adapting to the embossing requirements of PVC artificial leather of different thicknesses and specifications, improving the versatility and flexibility of the equipment. For example, for thinner PVC artificial leather, the distance between the embossing roller and the flattening roller can be appropriately reduced to obtain a clear embossing effect; for thicker artificial leather, the distance can be increased to avoid damage to the artificial leather due to excessive pressure. This equipment integrates embossing and winding functions, realizing continuous operation of PVC artificial leather embossing production. During the production process, frequent manual intervention is not required; the process from embossing to winding can be completed automatically, greatly improving production efficiency and reducing labor intensity.

[0019] Secondly, the winding mechanism of this utility model uses a bolt connection between the first semicircular ring, the second semicircular ring, the third semicircular ring and the fourth semicircular ring to fix the winding roller. This design makes the installation and disassembly of the winding roller very convenient and quick. The winding roller can be easily removed or installed simply by loosening the bolts, which greatly saves time and labor costs. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides the following technical solution: Example

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 A PVC artificial leather embossing device includes an embossing mechanism 1, and a winding mechanism 2 is provided on the left side of the embossing mechanism 1; The embossing mechanism 1 includes a bottom frame 101 and a top frame 102. A hydraulic telescopic rod 103 is fixedly connected to the bottom wall of the bottom frame 101. A fixing ring 104 is fixedly connected to the top of the hydraulic telescopic rod 103. A connecting rod 105 is rotatably connected inside the fixing ring 104. A flattening roller 106 is fixedly connected to the inner side of the connecting rod 105. Grooves are provided at both the front and rear ends of the bottom frame 101 and the top frame 102. An electric push rod 107 is installed in the groove. A connecting ring 108 is fixedly connected to the output end of the electric push rod 107. A support rod 109 is rotatably connected inside the connecting ring 108. An embossing roller 110 is fixedly connected to the inner side of the support rod 109. A fixing rod 111 is fixedly connected to the bottom of the top frame 102.

[0025] Specifically, there are four hydraulic telescopic rods 103, four fixing rings 104, and four connecting rods 105. Two of the hydraulic telescopic rods 103, two fixing rings 104, and two connecting rods 105 are located at the front and rear ends inside the bottom frame 101, respectively, and the other two hydraulic telescopic rods 103, two fixing rings 104, and two connecting rods 105 are located at the front and rear ends inside the top frame 102, respectively.

[0026] Specifically, there are four electric push rods 107, connecting rings 108 and support rods 109, with two of them located at the front and rear ends inside the bottom frame 101, and the other two electric push rods 107, connecting rings 108 and support rods 109 located at the front and rear ends inside the top frame 102.

[0027] Specifically, guide grooves are provided on the inner walls of the front and rear right sides of the bottom frame 101 and the top frame 102, and four fixing rings 104 and connecting rods 105 are respectively located in the guide grooves provided on the inner walls of the front and rear right sides of the bottom frame 101 and the top frame 102.

[0028] Specifically, there are two flattening rollers 106 and two embossing rollers 110. The two flattening rollers 106 and the two embossing rollers 110 are respectively the top inside of the bottom frame 101 and the bottom inside of the top frame 102. There are multiple fixing rods 111. The top frame 102 is fixedly connected to the top of the bottom frame 101 through multiple fixing rods 111 fixedly connected to the bottom.

[0029] Through the above technical solution, the embossing mechanism 1 is adjusted according to the thickness and embossing requirements of the PVC artificial leather. The internal wiring connection of the electric push rod 107 is existing technology and will not be described in detail here. When the electric push rod 107 is started, its output end pushes the connecting ring 108. The connecting ring 108 drives the support rod 109 and the embossing roller 110 to move, thereby adjusting the distance between the embossing roller 110 and the flattening roller 106 to achieve appropriate embossing pressure and depth. At the same time, the hydraulic telescopic rod 103 can also assist in adjusting the position of the flattening roller 106 to ensure that the PVC artificial leather can pass smoothly during the embossing process. When the motor 201 is started, it drives the second rotating rod 203 to rotate. The second rotating rod 203 drives the take-up roller 210 to rotate through the first connecting seat 204 and the first semicircular ring 205. At the same time, the first rotating rod 202 and its third semicircular ring 208 also rotate synchronously with the take-up roller 210 to achieve take-up. In this process, one end of the PVC artificial leather to be embossed is introduced into the embossing mechanism 1, allowing it to pass sequentially between the flattening roller 106 and the embossing roller 110. As the PVC artificial leather passes through the flattening roller 106, it undergoes preliminary flattening treatment, removing wrinkles and unevenness from the surface. Then, the artificial leather enters between the embossing roller 110 and the flattening roller 106. Under the pressure of the embossing roller 110, the desired texture pattern is formed on the surface of the artificial leather. The positions of the flattening roller 106 and the embossing roller 110 can be easily adjusted by the hydraulic telescopic rod 103 and the electric push rod 107, thereby adapting to the embossing requirements of PVC artificial leather of different thicknesses and specifications, and improving the versatility and flexibility of the equipment. For example, for thinner PVC artificial leather, the gap between the embossing roller 110 and the flattening roller 106 can be appropriately reduced to obtain a clear embossing effect. For thicker artificial leather, the gap can be increased to avoid damage to the artificial leather due to excessive pressure. Example

[0030] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 Furthermore, based on Embodiment 1, the following is obtained: the winding mechanism 2 includes a motor 201 and a first rotating rod 202. A second rotating rod 203 is fixedly connected to the output end of the motor 201. A first connecting seat 204 is fixedly connected to the end of the second rotating rod 203 away from the motor 201. A first semi-circular ring 205 is fixedly connected to the inner side of the first connecting seat 204. A second semi-circular ring 206 is fixedly connected to the top left and right sides of the first semi-circular ring 205 by bolts. A second connecting seat 207 is fixedly connected to the inner side of the first rotating rod 202. A third semi-circular ring 208 is fixedly connected to the inner side of the second connecting seat 207. A fourth semi-circular ring 209 is fixedly connected to the top left and right sides of the third semi-circular ring 208 by bolts. A winding roller 210 is engaged at the top of the first semi-circular ring 205 and the third semi-circular ring 208.

[0031] Specifically, the motor 201 is fixedly connected to the front left side of the base frame 101, the first rotating rod 202 is rotatably connected to the rear left side of the base frame 101, and the second rotating rod 203 is rotatably connected to the front left side of the base frame 101.

[0032] Through the above technical solution, the take-up roller 210 is placed in a suitable position. First, the first semi-circular ring 205 and the third semi-circular ring 208 are separated. One end of the take-up roller 210 is placed on the third semi-circular ring 208. Then, the first semi-circular ring 205 and the third semi-circular ring 208 are aligned. The first semi-circular ring 205, the second semi-circular ring 206, the third semi-circular ring 208, and the fourth semi-circular ring 209 are fixedly connected by bolts, thereby firmly installing the take-up roller 210 on the first rotating rod 202 and the second rotating rod 203. The PVC after embossing treatment... Artificial leather is output from the right side of the embossing mechanism 1. As the take-up roller 210 continues to rotate, the embossed PVC artificial leather is evenly wound onto the take-up roller 210. The internal wiring connection of the motor 201 is existing technology and will not be described in detail here. When the winding reaches a certain amount or the production task is completed, the motor 201 is stopped, the take-up roller 210 is removed, and the entire embossing production process is completed. This makes the installation and removal of the take-up roller 210 very convenient and quick. The take-up roller 210 can be easily removed or installed simply by loosening the bolts, which greatly saves time and labor costs.
