[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0022] Please see Figure 1-3 The leather cutting machine in this embodiment includes a base 1, with support columns 2 fixed on both the left and right sides of the top of the base 1, a drive box 3 fixed on the right side of the base 1, and a conveying assembly 4 fixed on the inner bottom wall of the drive box 3, which extends through to the left side wall of the inner cavity of the base 1. The conveying assembly 4 can transport the cut leather waste.
[0023] Furthermore, the conveying assembly 4 includes a first motor fixed to the bottom wall of the drive box 3 and penetrating the left side wall of the drive box 3. The output shaft of the first motor is fixed with a connecting column rotatably connected to the left side wall of the inner cavity of the base 1 and penetrating the right side wall of the base 1. An active roller is fixed to the outer surface of the connecting column. A driven roller on the back of the active roller is movably connected between the left and right side walls of the inner cavity of the base 1. Both the active roller and the driven roller are rotatably connected to the inner cavity of the base 1 through fixed bearings. The bearings can protect the rotating parts and prevent damage due to force. By bearing the force from the rotating shaft and the rotating support, the stability during the rotation process is maintained. A transmission belt is connected to the outer surface of the active roller and the driven roller. The first motor drives the connecting column to rotate, so that the connecting column drives the active roller to rotate at the same time. The active roller drives the driven roller to rotate, and the transmission belt is driven to transport the leather. At the same time, the cutter 607 cuts the leather.
[0024] Furthermore, a work box 5 is fixed to the right side of the right support column 2, and a hazard sign is fixed to the front of the work box 5. By setting the hazard sign, the staff can be reminded to pay attention at all times when the equipment is running, and to avoid getting close to prevent accidents and improve the safety of the working environment. A processing mechanism 6 is fixed to the inner bottom wall of the work box 5, which penetrates the right support column 2 and extends to the right side of the left support column 2. A blower assembly 7 is fixed to the opposite side of the two supports 2 to prevent the waste material after cutting from falling outside the conveying assembly 4.
[0025] Understandably, both blower assemblies 7 consist of a fixed plate, a small motor, and a fan. The opposite sides of the two fixed plates are fixed to the support column 2, and the opposite sides of the two fixed plates are hinged to the small motors. The small motors are tilted to keep the residue generated after cutting the leather on the conveyor belt when the conveyor assembly 4 transports the residue, preventing it from falling into the conveyor assembly 4 and causing contamination, which would prevent the conveyor assembly 4 from operating. The fan is fixed to the shaft of the small motor. The bottom of the base 1 is fixed with six support feet 8. The front of the base 1 is fixed with a receiving box 9 for collecting cutting waste. A drawer is movably connected inside the receiving box 9. The bottom of the drawer is fixed with two handles, both of which are U-shaped. The U-shaped handles are not only easier to pick up, but also more convenient and aesthetically pleasing. After the leather residue after cutting is transported into the receiving box 9, the drawer can be lifted with the handles to clean or sanitize the residue inside.
[0026] In this embodiment, the processing mechanism 6 presses the leather and then the conveying component 4 conveys the leather, so that the processing mechanism 6 and the conveying component 4 cooperate to cut and press the leather. At the same time, the blowing component 7 can collect the waste material after cutting and finally collect it into the receiving box 9, thus achieving the purpose of high cutting efficiency and saving time and effort.
[0027] Please see Figure 4-5 To achieve high cutting efficiency, the processing mechanism 6 in this embodiment includes a second motor 601 fixed to the bottom wall of the work box 5 and penetrating the right support column 2. Stabilizing columns are fixed to the bottom of both the first and second motors 601. Both the first and second motors 601 are fixed to the drive box 3 and the bottom wall of the work box 5 via these stabilizing columns. The stabilizing columns not only support and fix the motors but also reduce the frequency of motor vibration during operation, thereby reducing noise and preventing reduced motor lifespan due to vibration. The output shaft of the second motor 601 is fixed with a threaded rod 602 rotatably connected to the left support column 2. A threaded hole adapted to the threaded rod 602 is provided in the moving block 604. The threaded rod 602 is rotatably connected to the support column 2 via ball bearings. Using ball bearings improves rotational accuracy and stability, and also supports a certain weight load. This reduces rotational friction and indirectly increases the service life of the equipment.
[0028] It should be noted that two limiting rods 603 are fixed on the top of the threaded rod 602 on one side of the two opposing pillars 2. The moving block 604 has movable holes that are adapted to the limiting rods 603. When the threaded rod 602 is driven to rotate, due to the restriction of the two limiting rods 603, the threaded rod 602 will not be driven to rotate, but can only move left and right. The outer surface of the threaded rod 602 is threadedly connected to the moving block 604 through which the limiting rods 603 pass. Four electric telescopic rods 605 are fixed at the bottom of the moving block 604. A mounting bracket 606 is fixed to the bottom of the assembly. A cutter 607 is fixed at the central axis of the bottom of the mounting bracket 606. Pressing rollers 608 distributed on the front and rear sides of the cutter 607 are rotatably connected to the bottom of the mounting bracket 606. Rotating rods that are rotatably connected to the left and right sides of the mounting bracket 606 are fixed at the axis of each pressing roller 608. The pressing rollers 608 are movably connected to the mounting bracket 606 through the rotating rods and cooperate with the conveying assembly 4. While pressing the material, the leather can be smoothed to avoid deviation in the cutting angle caused by the protrusion of the leather, which would ultimately affect the product quality.
[0029] In this embodiment, the threaded rod 602 engages with the moving block 604, causing the moving block 604 to move left and right. As the moving block 604 moves, the bottom structure moves synchronously to the top of the leather to be cut. Then, the electric telescopic rod 605 presses down to press and cut the leather with the cutter 607 and the pressing roller 608, achieving high cutting efficiency and saving time and effort.
[0030] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.
[0031] The working principle of the above embodiments is as follows:
[0032] First, the leather to be cut is placed between the conveyor belt and the pressing roller 608. The second motor 601 is started, and the output shaft of the second motor 601 drives the threaded rod 602 to start rotating. Due to the restriction of the two limit rods 603, the moving block 604 can only move left and right when it engages with the threaded rod 602. While the moving block 604 moves left and right, it drives the mounting frame 606, the cutter 607 and the pressing roller 608 to move simultaneously. After moving to the place where it needs to be cut, it stops. Then, the electric telescopic rod 605 is started to push the mounting frame 606 to drive the cutter 607 and the pressing roller 608 to press down and compress the leather. Then, the conveying component 4 and the blowing component 7 are started. While the leather is moved by the conveying component 4, the cutter 607 cuts the leather and the pressing roller 608 presses it down. At this time, the blowing component 7 blows the small material after the leather is cut to the middle of the conveyor belt. The small material will then be conveyed to the receiving box 9 for collection. This achieves the purpose of high cutting efficiency, saving time and labor.
