Description

Technical Field

[0001] This invention relates to the field of synthetic leather production technology, and in particular to a cutting device for synthetic leather production and processing. Background Technology

[0002] Synthetic leather is a plastic product that mimics the composition and structure of natural leather and can be used 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 has 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 balls. Patent application number CN202121894210.1 discloses a cutting device for synthetic leather production and processing, including a workbench surface. A cutting box is fixedly installed on the upper side of the workbench. A threaded rod driven by a motor is rotatably mounted on the top of the cutting box. A movable seat that slides left and right on the top of the cutting box is threaded onto the threaded rod. A cutting device is located below the movable seat. A dust collection box is installed below the workbench surface. The left side of the cutting box is connected to the left side of the dust collection box via an air supply channel. Several air inlets are opened on the right side of the cutting box. An exhaust fan is installed on the right side of the dust collection box. Corresponding air inlets are located on the inner wall of the right side of the dust collection box. An air filter and a filter cleaning mechanism are installed at the air inlet of the exhaust fan. The filter cleaning mechanism includes a filter brush and an electric telescopic rod. The filter brush is located on the left side of the air filter, and a slider is fixed to its top and slidably mounted on the inner right wall of the dust collection box. The rear side of the slider is connected to the output shaft end of the electric telescopic rod mounted on the inner wall of the dust collection box. A sliding cover is installed at the bottom of the dust collection box. The cutting device includes a cutting motor mounted on a movable base and a cutting blade mounted on the output shaft end of the cutting motor. The cutting motor and the movable base are connected by an electric pneumatic rod. The motor is mounted on the outer left wall of the cutting box, and its output shaft is connected to a threaded rod. However, the dust is mainly generated by the rotating cutting blade, and a large amount of dust is difficult to completely clean. Some dust adheres to the surface of the synthetic leather, affecting the product's appearance. Manual re-cleaning results in a high cost. Summary of the Invention

[0003] The present invention aims to solve the problems existing in the prior art by providing a cutting device for synthetic leather production and processing, which can reduce dust generation and improve cleanliness, save manpower and avoid manual cleaning, ensure product quality through a stable cutting process, and improve efficiency by processing quickly and saving time.

[0004] The technical solution adopted by this invention to solve its technical problem is as follows: This cutting device for synthetic leather production and processing includes a base and a cutter. A first upright is installed on the top of the base, a cylinder is installed on the top of the first upright, a lifting plate is provided at the bottom of the cylinder, and the cutter is installed at the bottom of the lifting plate. A cutting table is fixedly connected to the top of the base, a cutting board is installed on the top of the cutting table, and the cutting board is directly below the cutter. An inner chamber is provided inside the cutting table. A first air hole is opened on the top of the cutting table, and a second air hole is opened on the side of the cutting table. There are multiple first air holes and multiple second air holes, which are connected to the inner chamber. An industrial vacuum cleaner is provided on the side of the base, and a transmission pipe is fixedly connected to the side of the industrial vacuum cleaner. The transmission pipe is connected to the cutting table and the inner chamber. An inner hole is opened on the side of the first upright, and there are multiple inner holes. A second upright is installed on the top of the base, and two conveying rollers are installed inside the second upright.

[0005] A fixed platform is fixedly connected to the top of the base, the fixed platform is connected to the cutting table, an optical axis is fixedly connected to the top of the fixed platform, the top of the optical axis is connected to the first upright, a linear bearing is installed inside the lifting plate, the optical axis is inside the linear bearing, and there are four optical axes and four linear bearings.

[0006] Synthetic leather material is conveyed by two conveyor rollers and laid flat on top of the cutting table. Once the industrial vacuum cleaner is activated, it draws air from the inner chamber through a transmission pipe, creating a negative pressure inside. This causes the synthetic leather material to be sucked in by multiple first air holes on top of the cutting table, improving its flatness. The cylinder then extends, driving the lifting plate and cutter downwards rapidly. The cutter quickly and effectively cuts the flat synthetic leather material. After cutting, the cylinder retracts, causing the lifting plate and cutter to return to their original positions quickly. During the up-and-down movement of the lifting plate and cutter, four linear bearings interact with four optical axes, effectively limiting and ensuring the accuracy of the lifting plate and cutter, preventing deviation. A small amount of dust or dirt in the working environment is sucked into the inner chamber through multiple second air holes and then collected by the industrial vacuum cleaner via a transmission pipe. The entire process reduces dust generation, improves cleanliness, saves manpower, avoids manual cleaning, ensures stable cutting, guarantees product quality, and saves time and increases efficiency.

[0007] To further improve the design, the base is rounded on the sides and the top of the cutting table is also rounded. The rounded corners provide effective protection and reduce direct injury to workers from sharp right-angled edges.

[0008] Further improvements include a controller mounted on the surface of the industrial vacuum cleaner and an output pipe mounted on the side of the industrial vacuum cleaner. The controller is used to turn the industrial vacuum cleaner on, set it, pause it, and turn it off. Air passes through the transmission pipe to reach the interior of the industrial vacuum cleaner. After dust or dirt is filtered inside the industrial vacuum cleaner, the air is discharged through the output pipe, making it efficient and convenient to use.

[0009] In a further improvement, the lifting plate is provided with a sliding hole inside, which is connected to the linear bearing. The optical axis is located inside both the linear bearing and the sliding hole. The sliding hole provides a sliding path, and the sliding hole and the linear bearing cooperate with each other to facilitate the passage of the optical axis.

[0010] Further improvements include a column fixedly connected to the bottom of the lifting plate, a fixed plate fixedly connected to the bottom of the column, a first spring fixedly connected to the bottom of the fixed plate, a pressure plate fixedly connected to the bottom of the first spring, a protective pad fixedly connected to the bottom of the pressure plate, and a movable column fixedly connected to the top of the pressure plate. The fixed plate has movable holes inside, and the movable column is inserted into these holes. There are multiple columns, first springs, movable columns, and movable holes. The pressure plate moves downwards with the lifting plate, pressing down on the synthetic leather to further secure it and facilitate rapid cutting by the cutter. The protective pad is in direct contact with the synthetic leather, effectively protecting it and reducing indentations. Multiple first springs contract under pressure, and multiple movable columns move within multiple movable holes, forming a buffer to effectively control the cutting depth.

[0011] To further improve the design, there are two pressure plates, which are distributed on the front and rear sides of the cutter. The two pressure plates exert the same force and cooperate with each other to further improve the stability of the cutting process.

[0012] Further improvements include a mounting base fixedly connected to the bottom of the lifting plate, with a mounting groove at the bottom of the mounting base. The mounting groove has a T-shaped structure, and a mounting strip is fixedly connected to the top of the cutter. The top of the cutter and the mounting strip are simultaneously inserted into the mounting groove. The mounting base is close to the inner hole, which provides effective force and facilitates operation by workers. The cutter is installed using the mounting groove and mounting strip, making installation simple, disassembly convenient, and replacement easy, saving time and manpower.

[0013] Further improvements include a first through hole on the side of the mounting base, a second through hole inside the cutter, a threaded hole on the side of the mounting base, and a first bolt on the side of the mounting base. The first bolt passes through the first and second through holes and is threaded into the threaded hole. There are two first bolts. An auxiliary hole is provided on the side of the cutter. The cutter is fixed using the first through hole, the second through hole, the threaded hole, and the first bolts to prevent the cutter from loosening during long-term use and to improve safety.

[0014] Further improvements include a convex groove on the top of the cutting table, with a base block fixedly connected to the bottom of the cutting board. Both the cutting board and the base block have a convex structure and are installed inside the convex groove. Multiple second springs are installed inside the convex groove, with a support plate fixedly connected to the top of each second spring. The base block and the cutting board are on top of the support plate, and the convex groove is close to the inner hole. When the cutting board is subjected to pressure from the cutting blade, the cutting board transmits the force to the base block and the support plate. The multiple second springs effectively contract and rebound, allowing the cutting board, base block, and support plate to move within the convex groove, releasing the pressure and reducing the impact force with the cutting blade, thus providing effective protection.

[0015] Further improvements include a T-shaped block fixedly connected to the top of the support plate, a T-shaped groove on the bottom of the base block, interlocking the T-shaped block and the T-shaped groove, a third through hole inside the base block, a threaded groove on the top of the T-shaped block, and a second bolt on the top of the base block. The second bolt passes through the third through hole and is threaded into the threaded groove. There are two second bolts. The cutting board and the base block are integral parts, and installation and fixation are achieved using the T-shaped block, T-shaped groove, third through hole, threaded groove, and second bolts. Installation is completed quickly, and disassembly and replacement are convenient, saving time and improving efficiency.

[0016] The beneficial effects of this invention are:

[0017] 1. Synthetic leather material is conveyed via two conveyor rollers and laid flat on top of the cutting table. Once the industrial vacuum cleaner is activated, it draws air from the inner chamber through a transmission pipe, creating a negative pressure inside. This causes the synthetic leather material to be sucked in by multiple first air holes on the top of the cutting table, improving its flatness. The cylinder then extends, driving the lifting plate and cutter downwards rapidly. The cutter quickly and effectively cuts the flat synthetic leather material. After cutting, the cylinder retracts, causing the lifting plate and cutter to return to their original positions quickly. During the up-and-down movement of the lifting plate and cutter, four linear bearings interact with four optical axes, effectively limiting and ensuring the accuracy of the lifting plate and cutter, preventing deviation. A small amount of dust or dirt in the working environment is sucked into the inner chamber through multiple second air holes and then collected by the industrial vacuum cleaner via a transmission pipe. The entire process reduces dust generation, improves cleanliness, saves manpower, avoids manual cleaning, ensures stable cutting, guarantees product quality, and saves time and increases efficiency.

[0018] 2. The pressure plate moves downward along with the lifting plate, pressing down on the synthetic leather to further fix it, facilitating rapid cutting by the cutter. The protective pad is in direct contact with the synthetic leather, effectively protecting it and reducing indentations. Multiple first spring components contract under pressure, and multiple movable columns move within multiple movable holes to form a buffer and effectively control the cutting depth. The two pressure plates exert the same force, working together to further improve the stability of the cutting process.

[0019] 3. The inner hole provides effective force, making it convenient for operators to operate. The cutter is installed using the mounting groove and mounting strip, which makes installation simple, disassembly convenient, and replacement easy, saving time and manpower. The cutter is fixed by the first through hole, the second through hole, the threaded hole and the first bolt, which prevents the cutter from loosening during long-term use and improves safety.

[0020] 4. After the cutting board is subjected to the pressure of the cutting blade, the cutting board transmits the force to the bottom block and support plate. Multiple second spring components effectively contract and rebound. The cutting board, bottom block, and support plate move within the convex groove, releasing the pressure and reducing the impact force with the cutting blade, thus forming effective protection. The cutting board and bottom block are integral parts, which are installed and fixed with the help of T-blocks, T-slots, third through holes, threaded grooves, and second bolts. Installation can be completed quickly, and disassembly and replacement can be convenient, saving time and improving efficiency. Attached Figure Description

The protective pad 24 is in direct contact with the synthetic leather, effectively protecting it and reducing indentations. The cutter 2 quickly and effectively cuts the flat synthetic leather material. Multiple first springs 22 are compressed and contracted, and multiple movable columns 25 move within multiple movable holes 26 to form a buffer and control the effective cutting depth. At the same time, after the cutting plate 7 is subjected to the pressure of the cutter 2, the cutting plate 7 transmits the force to the bottom block 36 and the support plate. 38. Multiple second spring components 37 effectively retract, releasing pressure and reducing the collision force with the cutting blade 2, forming effective protection. After cutting, the cylinder 4 retracts, driving the lifting plate 5 and the cutting blade 2 to quickly return to their original positions. During the up-and-down movement of the lifting plate 5 and the cutting blade 2, four linear bearings 18 and four optical axes 17 interact to effectively limit and ensure the accuracy of the lifting plate 5 and the cutting blade 2, preventing deviation. A very small amount of dust or dirt in the working environment is sucked into the inner chamber 8 by multiple second air holes 10, and then reaches the industrial vacuum cleaner 11 through the transmission pipe 12 for centralized collection. The whole process reduces dust generation, improves cleanliness, saves manpower, avoids manual cleaning, ensures stable cutting process, guarantees product quality, and saves time and improves efficiency.
