Description

Technical Field

[0001] This invention relates to the field of leather processing equipment technology, specifically to a membrane separation device for synthetic leather and its usage method. Background Technology

[0002] Synthetic leather, also known as simulated natural leather, is a plastic product that mimics the composition and structure of natural leather and can serve as a substitute. It is typically made with an impregnated non-woven fabric as the mesh layer and a microporous polyurethane layer as the grain layer. Both its front and back are very similar to leather, and it possesses a certain degree of breathability, making it closer to natural leather than ordinary artificial leather. It is widely used in the production of shoes, boots, bags, and sports equipment. As a promising emerging industry, the synthetic leather industry is increasingly attracting investors. With technological advancements, high-tech methods such as ultrasonic technology, electronic technology, microwave technology, and high-pressure technology will be widely applied to the synthetic leather field. Due to the material differences between the membrane and the fabric, the waste has low utilization value; only by separating the two materials can it be recycled. Membrane-fabric separators are needed for this separation.

[0003] Currently, when processing synthetic leather for fabric-film separation, the raw material is laid flat on the workbench, making it inconvenient to separate the two materials. In addition, external forces and vibrations are inevitable during the separation process, causing the structure to shake and further affecting the fabric-film separation process. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: a membrane separation device for synthetic leather, comprising:

[0005] The machine body has a support frame fixedly connected to its top and near the left end by screws, and a take-up roller is installed inside the machine body and near the right end.

[0006] Also includes:

[0007] The separation mechanism includes a lifting rod fixed to the top of a support frame. A U-shaped bracket is fixedly connected to the output end of the lifting rod, and a roller is rotatably connected to the bottom of the U-shaped bracket. Dividing teeth are fixedly connected to the outer surface of the roller, and a servo motor is fixedly connected to the bottom of the outer surface of the U-shaped bracket. The output end of the servo motor is fixedly connected to the end of the outer surface of the roller via a coupling. A pressing wheel is mounted on the outer surface of the U-shaped bracket, near the end of the outer surface of the roller, via a rod. By extending the lifting rod, the U-shaped bracket is pushed downwards, causing the roller and the pressing wheel to be pulled along with it. The roller moves downwards, adjusting its height. A servo motor drives the roller to rotate rapidly, causing the dividing teeth to rotate along with it. The top of the support roller is higher than the top of the machine body, which lifts the synthetic leather, making the dividing teeth and the synthetic leather material into linear contact. This reduces the contact area and facilitates rapid film separation. The winding roller continues to separate the synthetic leather material through film separation. Meanwhile, as the pressing roller moves downwards, it applies pressure to the anti-wrinkle component's anti-disengagement hook, which helps with subsequent anti-wrinkle treatment of the synthetic leather material, thus connecting the structures together.

[0008] The lifting assembly has a rectangular opening at the top of the machine body near the support frame. A support top roller is rotatably connected to the inner surface of the machine body near the rectangular opening. A rotating pressure bar is fixedly connected to the outer end of the support top roller, and a ball is rotatably connected to the outer surface of the rotating pressure bar. Synthetic leather material passes over the top of the support top roller, supporting the synthetic leather material so that the synthetic leather material directly below the dividing teeth protrudes upward, which helps the dividing teeth to separate the synthetic leather from the film. At the same time, when the winding roller winds up the separated synthetic leather material, the tension on the synthetic leather material causes the support top roller to rotate. At this time, the rotating pressure bar rotates circumferentially with the support top roller. The rotating support top roller can apply pressure to the pressure drive rod on the impurity removal assembly, which helps with subsequent self-cleaning. The interaction between the structures makes the structures connected together.

[0009] Preferably, the opening of the U-shaped bracket faces downward, and the bottom of the outer surface of the U-shaped bracket is provided with a rolling hole that matches the end of the outer surface of the roller, and the dividing teeth are evenly distributed on the outer surface of the roller.

[0010] Preferably, the top of the machine body and near the rectangular opening has a notch adapted to the rotating pressure bar, and the outer surface of the rotating pressure bar has a rolling groove adapted to the ball.

[0011] Preferably, an anti-wrinkle component is provided at the top and near the right end of the machine body. The anti-wrinkle component includes a connecting pressure plate and a limiting groove. The bottom end of the connecting pressure plate is rotatably connected to the top and near the right end of the machine body. The limiting groove is located at the top of the machine body and near the connecting pressure plate. An anti-disengagement hook is provided at the top of the connecting pressure plate. A scraper plate is fixedly connected to the outer surface of the connecting pressure plate. A rolling module is provided on the outer surface of the connecting pressure plate and near the scraper plate. When the pressing wheel moves downward, the outer surface of the pressing wheel contacts the anti-disengagement hook, which prevents it from falling off the pressing wheel. This makes the pressing wheel support the U-shaped bracket more stable. As it continues to move downward, the connecting pressure plate rotates counterclockwise after being pressed. At this time, the scraper plate and the rolling module are driven to rotate together. The bottom of the scraper plate contacts the synthetic leather material. As the synthetic leather material moves continuously, the synthetic leather material is scraped flat, making it less prone to wrinkles. This helps to separate the synthetic leather material from the fabric.

[0012] Preferably, there are two connecting pressure plates, which are symmetrically arranged along the scraper plate. The anti-disengagement hook is integrated with the connecting pressure plate, and the connecting pressure plate is inclined.

[0013] Preferably, the rolling module includes a curved elastic bar. The top end of the curved elastic bar is fixedly connected to the outer surface of the connecting pressure plate, and a semi-cylindrical pressing member is fixedly connected to the bottom end of the curved elastic bar. A cylindrical roller is rotatably connected to the bottom of the semi-cylindrical pressing member. When the connecting pressure plate is pressed, it rotates, causing the entire rolling module to rotate towards the limiting groove. The semi-cylindrical pressing member is embedded in the limiting groove, and under the elastic pressing force applied by the curved elastic bar, the synthetic leather material is pressed and tensioned, preventing loosening. As the synthetic leather material moves, the cylindrical roller rolls, which not only provides rolling pressure to the synthetic leather material but also ensures smooth movement of the synthetic leather material.

[0014] Preferably, there are two curved elastic bars, and the two curved elastic bars are symmetrically arranged along the center position of the semi-cylindrical pressing member. The bottom of the semi-cylindrical pressing member is provided with a rolling groove that is compatible with the cylindrical roller.

[0015] Preferably, a dust removal component is provided inside the machine body near the rectangular opening. The dust removal component includes a fan and a frame. The fan is mounted on the left side of the outer surface of the machine body with screws. The outer edge of the frame is fixedly connected to the inner surface of the machine body near the rectangular opening. A guide rail is fixedly connected to the outer surface of the frame away from the fan. A pressure-bearing drive rod is slidably connected inside the guide rail. A return spring is fixedly connected to the bottom of the pressure-bearing drive rod. A dovetail scraper is fixedly connected to the outer surface of the pressure-bearing drive rod. A dust removal filter is fixedly connected to the center of the outer surface of the frame. When the fan is turned on, it operates using the suction power of the fan. The system creates an airflow that carries the segmented teeth to absorb the fibrous impurities generated after the processing of synthetic leather raw materials. The airflow carries these impurities through the rectangular opening and filters them through the impurity removal screen, achieving timely impurity removal. Simultaneously, as the pressure-driven rod is pressed by the rotating pressure bar, it causes the dovetail scraper to move downwards, and the return spring is compressed. When the rotating pressure bar disengages from the pressure-driven rod, the return spring's elasticity causes the pressure-driven rod to move the dovetail scraper upwards. This reciprocating motion of the dovetail scraper cleans the impurities adhering to the outer surface of the impurity removal screen, reducing impurity adhesion and preventing clogging.

[0016] Preferably, the bottom end of the reset spring is fixedly connected to the bottom of the inner surface of the guide rail, the output end of the fan passes through the outer surface of the body and extends into the interior, and the pressure-bearing drive rod is set in an arc shape.

[0017] A method for separating synthetic leather using a membrane includes the following steps:

[0018] Step 1: Pre-separate the ends of the synthetic leather raw material to be processed, lay it flat on the top of the machine body, pass the pre-processed synthetic leather raw material through the anti-wrinkle component, and go around the top of the support roller, enter the machine body through the rectangular opening, and wrap it around the outer surface of the take-up roller.

[0019] Step 2: Using the extension of the lifting rod, the U-shaped bracket is pushed downwards. At this time, the roller and the pressing wheel are moved downwards together, and the roller is driven to rotate rapidly by the servo motor, so that the dividing teeth rotate together. The top of the supporting top roller is higher than the top of the machine body, and the synthetic leather raw material is continuously separated by the winding roller.

[0020] Step 3: When the winding roller winds up the separated synthetic leather raw material, the tension on the synthetic leather raw material causes the support top roller to rotate. At this time, the rotating pressure bar rotates in a circle with the support top roller. The rotating support top roller can apply pressure to the pressure drive rod on the impurity removal component.

[0021] Step 4: When the pressing wheel moves downward, the outer surface of the pressing wheel contacts the anti-disengagement hook. As it continues to move downward, the connecting pressure plate is pressed and rotates counterclockwise. At this time, the scraper plate and the rolling module are driven to rotate together. The bottom of the scraper plate contacts the synthetic leather material and, as the synthetic leather material moves continuously, the synthetic leather material is scraped flat.

[0022] Step 5: After the connecting pressure plate is pressed, it rotates, causing the entire rolling module to rotate towards the limiting groove. The semi-cylindrical pressing part is embedded in the limiting groove, and under the elastic pressing force applied by the curved spring strip, the synthetic leather material is pressed. As the synthetic leather material moves, the cylindrical roller rolls, allowing the synthetic leather material to move smoothly.

[0023] Step Six: Turn on the fan to start operation. The suction force of the fan creates an airflow that carries the fibrous impurities generated after the processing of the synthetic leather raw materials. At this time, the fibrous impurities carried by the airflow pass through the rectangular opening and are filtered by the impurity removal filter. Simultaneously, as the pressure drive rod is pressed, it will drive the dovetail scraper downward, and the return spring will be compressed. When the rotating pressure bar is disengaged from the pressure drive rod, the elastic force of the return spring will cause the pressure drive rod to drive the dovetail scraper upward, and the dovetail scraper will move up and down back and forth.

[0024] This invention provides a membrane separation device for synthetic leather and its usage method. It has the following beneficial effects:

[0025] I. The synthetic leather fabric separation device and its usage method utilize the extension of the lifting rod to drive the roller and pressing wheel downwards, thereby adjusting the height of the roller. The roller is driven to rotate rapidly by a servo motor, causing the dividing teeth to rotate along with it. The top of the supporting roller is higher than the top of the machine body, thus supporting the synthetic leather and making the dividing teeth and synthetic leather raw material into linear contact, reducing the contact area and facilitating rapid fabric separation. The fabric separation process of the synthetic leather raw material is continuously carried out by the winding roller. At the same time, when the pressing wheel moves downwards, it can apply pressure to the anti-wrinkle component to prevent dislodgement, which helps to prevent wrinkles in the subsequent anti-wrinkle treatment of the synthetic leather raw material.

[0026] II. The synthetic leather fabric separation device and its usage method support the synthetic leather raw material through the support top roller, causing the synthetic leather raw material directly below the dividing teeth to bulge upwards, thereby facilitating the fabric separation of the synthetic leather by the dividing teeth. At the same time, when the winding roller winds up the separated synthetic leather raw material, the tension on the synthetic leather raw material causes the support top roller to rotate. At this time, the rotating pressure bar rotates circumferentially with the support top roller. The rotating support top roller can apply pressure to the pressure drive rod on the impurity removal component, thereby facilitating subsequent self-cleaning.

[0027] III. The synthetic leather fabric-film separation device and its usage method utilize the outer surface of the pressing roller in contact with the anti-detachment hook, which prevents the roller from falling off. This makes the pressing roller support the U-shaped bracket more stable. As it moves downward, the connecting pressure plate is pressed and rotates counterclockwise. At this time, the scraper plate and the rolling module are driven to rotate together. The bottom of the scraper plate contacts the synthetic leather raw material, and as the synthetic leather raw material moves continuously, it is scraped flat, making it less prone to wrinkles. This helps to separate the synthetic leather raw material from the fabric.

[0028] IV. The synthetic leather fabric separation device and its usage method utilize the pressure of the connecting plate to drive the entire rolling module to rotate towards the limiting groove. The semi-cylindrical pressing component is embedded in the limiting groove, and under the elastic pressing force applied by the curved spring strip, the synthetic leather raw material is pressed and tensioned, making it less prone to loosening. As the synthetic leather raw material moves, the cylindrical roller rolls, which not only allows the synthetic leather raw material to be pressed by rolling, but also allows the synthetic leather raw material to move smoothly.

[0029] V. The synthetic leather fabric membrane separation device and its usage method utilize the suction force of a fan to draw in fibrous debris carried by airflow. The fibrous debris passes through the rectangular opening and is filtered by the impurity removal filter, achieving timely impurity removal. Simultaneously, as the pressure-driven rod is pressed by the rotating pressure bar, the pressure-driven rod drives the dovetail scraper downwards, and the return spring is compressed. When the rotating pressure bar disengages from the pressure-driven rod, the return spring's elastic force causes the pressure-driven rod to drive the dovetail scraper upwards. The dovetail scraper moves up and down repeatedly, cleaning the impurities adhering to the outer surface of the impurity removal filter, reducing debris adhesion and preventing clogging.

[0041] First embodiment, such as Figures 1-4 As shown, the present invention provides a technical solution: a membrane separation device for synthetic leather, comprising:

[0042] The machine body 1 has a support frame 2 fixedly connected to its top and near the left end by screws, and a winding roller 3 is installed inside the machine body 1 near the right end. The winding roller 3 can wind up the processed synthetic leather raw material.

[0043] Also includes:

[0044] The separation mechanism 4 has a lifting rod 41 fixed to the top of the support frame 2. A U-shaped bracket 42 is fixedly connected to the output end of the lifting rod 41. A roller 43 is rotatably connected to the bottom of the U-shaped bracket 42. Dividing teeth 44 are fixedly connected to the outer surface of the roller 43. A servo motor 45 is fixedly connected to the bottom of the outer surface of the U-shaped bracket 42. The output end of the servo motor 45 is fixedly connected to the end of the outer surface of the roller 43 via a coupling. A pressing wheel 46 is mounted on the outer surface of the U-shaped bracket 42 near the end of the outer surface of the roller 43 via a rod. The extension of the lifting rod 41 pushes the U-shaped bracket 42 downwards. At this time, the roller 43 and the pressing wheel 46... Together they are moved downwards, thereby adjusting the height of the roller 43, and the roller 43 is driven to rotate rapidly by the servo motor 45, so that the dividing teeth 44 rotate together. With the top of the support roller 52 being higher than the top of the machine body 1, the synthetic leather is supported, so that the dividing teeth 44 and the synthetic leather raw material make linear contact, reducing the contact area, which helps to quickly separate the fabric and film. The synthetic leather raw material is continuously separated by the winding roller 3. At the same time, when the pressing roller 46 moves downwards, it can apply pressure to the anti-wrinkle component 6 anti-disengagement hook 63, which helps to prevent wrinkles in the subsequent processing of the synthetic leather raw material, thus connecting the structures together.

[0045] The opening of the U-shaped bracket 42 faces downward. The bottom of the outer surface of the U-shaped bracket 42 is provided with a rolling hole that matches the end of the outer surface of the roller 43, so that the roller 43 can roll. The dividing teeth 44 are evenly distributed on the outer surface of the roller 43.

[0046] Second embodiment, such as Figures 1-6 As shown, based on the first embodiment,

[0047] The lifting assembly 5 has a rectangular opening 51 on the top of the machine body 1 near the support frame 2. A support top roller 52 is rotatably connected to the inner surface of the machine body 1 near the rectangular opening 51. A rotating pressure bar 53 is fixedly connected to the outer end of the support top roller 52, and a ball 54 is rotatably connected to the outer surface of the rotating pressure bar 53. Synthetic leather material passes over the top of the support top roller 52. At this time, the support top roller 52 can support the synthetic leather material, so that the synthetic leather material directly below the dividing teeth 44 protrudes upward, which helps the dividing teeth 44 to separate the synthetic leather from the film. At the same time, when the winding roller 3 winds up the separated synthetic leather material, the tension on the synthetic leather material causes the support top roller 52 to be driven to rotate. At this time, the rotating pressure bar 53 rotates circumferentially with the support top roller 52. The rotating support top roller 52 can apply pressure to the pressure drive rod 74 on the impurity removal assembly 7, which helps with subsequent self-cleaning. The interaction between the structures makes the structures connected together.

[0048] The top of the body 1 and near the rectangular opening 51 has a notch that matches the rotating pressure bar 53, so that the rotating pressure bar 53 can rotate and will not get stuck. The outer surface of the rotating pressure bar 53 has a rolling groove that matches the ball 54, so that the ball 54 can roll.

[0049] The third embodiment, such as Figures 1-4 and Figures 7-8 As shown, based on the first embodiment,

[0050] An anti-wrinkle component 6 is provided on the top of the body 1 near the right end. The anti-wrinkle component 6 includes a connecting pressure plate 61 and a limiting groove 62. The bottom end of the connecting pressure plate 61 is rotatably connected to the top of the body 1 near the right end. The limiting groove 62 is located on the top of the body 1 near the connecting pressure plate 61. An anti-disengagement hook 63 is provided on the top of the connecting pressure plate 61. A scraper plate 64 is fixedly connected to the outer surface of the connecting pressure plate 61. A rolling module 65 is provided on the outer surface of the connecting pressure plate 61 near the scraper plate 64. When the pressing roller 46 moves downward, the pressing... The outer surface of the pressure roller 46 contacts the anti-detachment hook 63, and the anti-detachment hook 63 can prevent the pressure roller 46 from falling off, thereby making the pressure roller 46 support the U-shaped bracket 42 more stably. As it continues to move downward, the connecting pressure plate 61 is pressed and rotates counterclockwise. At this time, the scraper plate 64 and the rolling module 65 are driven to rotate together. At this time, the bottom of the scraper plate 64 contacts the synthetic leather raw material, and as the synthetic leather raw material moves continuously, the synthetic leather raw material is scraped flat, making it less prone to wrinkles, which helps to separate the synthetic leather raw material from the fabric.

[0051] Two connecting pressure plates 61 are provided, and the two connecting pressure plates 61 are symmetrically arranged along the scraper plate 64, so that the connecting pressure plates 61 are balanced under pressure. The anti-disengagement hook 63 is integrated with the connecting pressure plate 61, and the connecting pressure plate 61 is inclined.

[0052] The rolling module 65 includes a curved elastic bar 651. The top end of the curved elastic bar 651 is fixedly connected to the outer surface of the connecting pressure plate 61. A semi-cylindrical pressing member 652 is fixedly connected to the bottom end of the curved elastic bar 651. A cylindrical roller 653 is rotatably connected to the bottom of the semi-cylindrical pressing member 652.

[0053] Two curved elastic bars 651 are provided, and the two curved elastic bars 651 are symmetrically arranged along the central position of the semi-cylindrical pressing member 652. The bottom of the semi-cylindrical pressing member 652 is provided with a rolling groove adapted to the cylindrical roller 653. When the connecting pressure plate 61 is pressed, it rotates, causing the entire rolling module 65 to be driven to rotate towards the limiting groove 62. The semi-cylindrical pressing member 652 is embedded in the limiting groove 62, and under the elastic pressing force applied by the curved elastic bars 651, the synthetic leather material is pressed and tensioned, making it less prone to loosening. As the synthetic leather material moves, the cylindrical roller 653 rolls, which not only makes the synthetic leather material receive rolling pressing, but also makes the synthetic leather material move smoothly.

[0054] Fourth embodiment, such as Figure 9As shown, a cleaning component 7 is installed inside the body 1 near the rectangular opening 51. The cleaning component 7 includes a fan 71 and a frame 72. The fan 71 is installed on the left side of the outer surface of the body 1 by screws. The outer edge of the frame 72 is fixedly connected to the inner surface of the body 1 near the rectangular opening 51. A guide rail 73 is fixedly connected to the outer surface of the frame 72 away from the fan 71. A pressure-bearing drive rod 74 is slidably connected inside the guide rail 73. A return spring 75 is fixedly connected to the bottom of the pressure-bearing drive rod 74. A dovetail scraper 76 is fixedly connected to the outer surface of the pressure-bearing drive rod 74. A cleaning filter screen 77 is fixedly connected to the center of the outer surface of the frame 72. When the fan 71 is turned on, the suction force of the fan 71 is used to clean the outer surface of the body 1. The airflow carrying the dividing teeth 44 absorbs the fibrous impurities generated after the processing of synthetic leather raw materials. At this time, the fibrous impurities carried by the airflow pass through the rectangular opening 51 and are filtered by the impurity removal filter 77, achieving the effect of timely impurity removal. Simultaneously, as the pressure-driven rod 74 is pressed by the rotating pressure bar 53, the pressure-driven rod 74 will drive the dovetail scraper 76 to move downward, and the return spring 75 will be compressed. When the rotating pressure bar 53 is disengaged from the pressure-driven rod 74, under the elastic force of the return spring 75, the pressure-driven rod 74 drives the dovetail scraper 76 to move upward. The dovetail scraper 76 moves up and down back and forth, thereby cleaning the impurities attached to the outer surface of the impurity removal filter 77, reducing the adhesion of impurities and preventing clogging.

[0055] The bottom end of the return spring 75 is fixedly connected to the bottom of the inner surface of the guide rail 73, so that it can be pressed by the pressure drive rod 74. The output end of the fan 71 passes through the outer surface of the body 1 and extends into the interior, so as to draw out the gas inside the body 1. The pressure drive rod 74 is set to be arc-shaped.

[0056] Guide rails 73 are provided on both sides of the impurity removal filter 77, so that the symmetrical pressure driving rods 74 on both sides are pressed together, which helps the dovetail scraper 76 to move downward smoothly. At the same time, the outer edge of the dovetail scraper 76 is in contact with the outer surface of the impurity removal filter 77, which helps the dovetail scraper 76 to effectively scrape away the impurities attached to the outer surface of the impurity removal filter 77. Since the impurity removal filter 77 is in a vertical state, it helps the scraped impurities fall off.

[0057] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.

5. The membrane separation device for synthetic leather according to claim 4, characterized in that: The bottom end of the reset spring (75) is fixedly connected to the bottom of the inner surface of the guide rail (73), the output end of the fan (71) passes through the outer surface of the body (1) and extends into the interior, and the pressure-driven rod (74) is set in an arc shape.

6. A method for separating synthetic leather using a membrane, characterized in that: Includes the following steps: Step 1: The ends of the synthetic leather raw materials to be processed are pre-separated and laid flat on the top of the machine body (1). The pre-processed synthetic leather raw materials are passed through the anti-wrinkle assembly (6), and pass around the top of the support top roller (52), enter the machine body (1) through the rectangular opening (51), and are wrapped around the outer surface of the take-up roller (3). Step 2: Using the extension of the lifting rod (41), the U-shaped bracket (42) is pushed downward. At this time, the roller (43) and the pressing wheel (46) are moved downward together. The roller (43) is driven to rotate rapidly by the servo motor (45), so that the dividing teeth (44) rotate together. The top of the supporting top roller (52) is higher than the top of the machine body (1), and the synthetic leather raw material is continuously separated by the winding roller (3). Step 3: When the take-up roller (3) takes up the synthetic leather raw material after separation, the tension of the synthetic leather raw material causes the support top roller (52) to rotate. At this time, the rotating pressure bar (53) rotates in a circle with the support top roller (52). At this time, the rotating support top roller (52) can apply pressure to the pressure drive rod (74) on the impurity removal component (7). Step 4: When the pressing wheel (46) moves downward, the outer surface of the pressing wheel (46) contacts the anti-disengagement hook (63). As it continues to move downward, the connecting pressure plate (61) is pressed and rotates counterclockwise. At this time, the scraper plate (64) and the rolling module (65) are driven to rotate together. At this time, the bottom of the scraper plate (64) contacts the synthetic leather material and moves continuously with the synthetic leather material, so that the synthetic leather material is scraped flat. Step 5: After the connecting pressure plate (61) is pressed, it rotates, causing the entire rolling module (65) to rotate towards the limiting groove (62). The semi-cylindrical pressing part (652) is embedded into the limiting groove (62), and under the elastic pressing force applied by the curved elastic strip (651), the synthetic leather material is pressed. As the synthetic leather material moves, the cylindrical roller (653) rolls, allowing the synthetic leather material to move smoothly. Step 6: Turn on the fan (71) to work. The suction of the fan (71) makes the outside air form an airflow that carries the dividing teeth (44) to suck up the fiber debris generated after the synthetic leather raw material is processed. At this time, the fiber debris carried by the airflow passes through the rectangular opening (51) and is filtered by the impurity removal filter (77). At the same time, as the pressure drive rod (74) is pressed, the pressure drive rod (74) will drive the dovetail scraper (76) to move downward, and the return spring (75) is compressed. When the rotating pressure bar (53) is separated from the pressure drive rod (74), under the elastic force of the return spring (75), the pressure drive rod (74) drives the dovetail scraper (76) to move upward, and the dovetail scraper (76) moves up and down back and forth.
