Utility Model Content
[0003] This invention aims to solve the problems existing in the prior art by providing a cutting device for the production and processing of leather bags. It can quickly adjust the distance between the cutters, save time and manpower, improve work efficiency, and has high flexibility to meet the needs of cutting leather bags to different sizes.
[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: This cutting device for leather production and processing of bags includes an operating table and a first cutting blade. A first support base is arranged on the left side of the operating table, and a support frame is fixedly connected to the top of the first support base. There are multiple support frames, and a feeding roller and a conveying roller are arranged on the top of the support frame. A second support base is arranged on the right side of the operating table, and multiple support frames and a conveying roller are arranged on the top of the second support base. A receiving roller is arranged on the top of the support frame. A first column is arranged on the side of the operating table, and a first machine is fixedly connected to the top of the first column. The machine consists of a first frame with a movable base inside. A first electric cylinder is mounted on the side of the first frame, with a piston rod at its output end. The piston rod is connected to the side of the movable base. An optical axis is fixedly connected inside the first frame. Multiple linear bearings and optical axes are housed within the movable base. A second electric cylinder is also located inside the movable base, with a piston rod at its bottom output end. A fixed plate is positioned at the bottom of the piston rod, and a drive motor is mounted at the bottom of the fixed plate. A rotating shaft is located at the output end of the drive motor. A first cutter is mounted on the first electric cylinder. Multiple first cutters are mounted longitudinally on the rotating shaft above the operating table. Two movable seats are located inside the first frame, and a first electric cylinder is mounted on each side of the first frame. The leather is fed onto the feeding roller, passes through the transfer roller and the operating table, and is finally wound up on the take-up roller. The first electric cylinders are controlled to extend or retract, and the piston rod pushes or pulls the movable seats to move back and forth along multiple optical axes, adjusting the position of the first cutters. The drive motor is activated, causing the rotating shaft to rotate the first cutters at high speed. The second electric cylinders are controlled to extend, and their piston rods extend downwards, moving the drive motor and the first cutters vertically downwards to the appropriate position. The first cutters then cut the conveyed leather. The multiple first cutters (first frame, first electric cylinder, movable seats, second electric cylinder, drive motor, and multiple cutters) allow for quick adjustment and simultaneous cutting of the leather. The entire process allows for rapid adjustment of the distance between the cutters, saving time and manpower, improving work efficiency, and offering high flexibility to meet the needs of cutting leather to different sizes.
[0005] To further improve the system, a motor is installed on the side of the support frame. The motor drives the receiving roller and provides the main power to ensure the normal transmission of the leather bags.
[0006] To further improve the design, the top side of the operating table is rounded, and the top of the support frame is rounded or chamfered. The rounded and chamfered corners increase effective protection, reduce the sharp right-angle edges of the structure, and reduce accidental damage to the leather and workers.
[0007] Further improvements include the following: a first bolt is provided inside the first column; a first mounting hole is opened inside the first column; a threaded groove is opened on the side of the operating table; the first bolt passes through the first mounting hole and connects with the threaded groove; there are multiple first bolts, multiple first mounting holes, and multiple threaded grooves; the first column is installed and fixed by multiple first bolts, multiple first mounting holes, and multiple threaded grooves; the first column and the first frame are easy to install and disassemble as a whole, and are convenient and quick to adjust and replace.
[0008] Further improvements include a number of threaded grooves exceeding the number of first mounting holes, multiple threaded grooves covering the side of the operating table, equal spacing between multiple threaded grooves, and easy adjustment of the distance between multiple first frames. The specific number of the first frame, first electric cylinder, moving seat, second electric cylinder, drive motor, and first cutter is also easy to adjust, further enhancing flexibility.
[0009] Further improvements include a second column on the side of the operating table, with a second frame fixedly connected to the top of the second column. The second frame is located to the left of the first frame and also includes a movable seat, an optical axis, a first electric cylinder, a second electric cylinder, and a drive motor. A second cutter is located on the side of the rotating shaft. The second cutter is horizontally positioned, while the multiple first cutters are used for longitudinal cutting and the second cutters for transverse cutting. Once the leather of the bag meets the length requirement, it can be directly cut, saving time and improving efficiency.
[0010] Further improvements include a second column that is fixed in the same way as the first column, with a second bolt and a second mounting hole inside. The second column is installed and fixed using multiple second bolts, multiple second mounting holes, and multiple threaded grooves. The second column and the second frame are easy to install and remove as a whole, and can be easily adjusted and replaced.
[0011] The beneficial effects of this utility model are: The leather is fed onto the feeding roller, passes through the transfer roller and operating table, and is finally wound up on the take-up roller. The first electric cylinder is controlled to extend or retract, and the piston rod pushes or pulls the moving seat to move back and forth along multiple optical axes, adjusting the position of the first cutter. The drive motor is turned on, and the rotating shaft drives the first cutter to rotate at high speed. The second electric cylinder is controlled to extend, and the piston rod of the second electric cylinder extends downward. The drive motor and the first cutter move vertically downward to the appropriate position, and the first cutter cuts the conveyed leather. There are multiple first cutters, including the first frame, the first electric cylinder, the moving seat, the second electric cylinder, the drive motor, and the first cutter. Multiple first cutters facilitate quick adjustment, and multiple first cutters cut the leather simultaneously. The distance between the cutters can be quickly adjusted throughout the process, saving time and manpower, improving work efficiency, and providing high flexibility to meet the needs of cutting leather to different sizes.
[0012] The first column is installed and fixed by multiple first bolts, multiple first mounting holes and multiple threaded grooves. The first column and the first frame are easy to install and dismantle as a whole, and are convenient and quick to adjust and replace. The distance between multiple first frames is easy to adjust. The specific number of the first frame, the first electric cylinder, the moving seat, the second electric cylinder, the drive motor and the first cutter is also easy to adjust, further improving flexibility.
[0013] Multiple first cutters cut longitudinally, and second cutters cut laterally. Once the leather meets the length requirements, it can be cut directly, saving time and improving efficiency. The second column is installed and fixed by multiple second bolts, multiple second mounting holes and multiple threaded grooves. The second column and the second frame are easy to install and remove as a whole, and can be easily and quickly adjusted and replaced. Attached Figure Description
