[0022] See also Figure 1 and Figure 2 , which is a leather trimming equipment of an embodiment of the present invention, includes a conveying component 20 for transporting leather, a cutting component 30, a receiving component 40 and a feeding component 50, and the cutting component 30, the receiving component 40 and the feeding component 50 are all installed on the conveying component 20; the conveying component 20 includes a conveyor belt 21, and the conveyor belt 21 includes a feeding end 210 and a discharging end 211 at both ends; the feeding component 50 includes a feeding roller 51 installed on one side of the feeding end 210 and a feeding driving member 52 for driving the feeding roller 51 to rotate; the receiving component 40 is a discharging roller 41 installed on one side of the discharging end 211 and a discharging driving member 42 for driving the discharging roller 41 to rotate; the cutting component 30 includes a blade 31 installed on one side of the material taking end and a cutting driving member 32 for driving the blade 31 to move, the cutting edge of the blade 31 is in the same direction as the conveying direction of the conveyor belt 21, and the movement direction of the blade 31 is perpendicular to the conveying direction of the conveyor belt 21.
[0023] The working principle of the leather trimming device of the present invention is as follows: first, the feed assembly 50 starts working; the feed drive 52 drives the feed roller 51 to rotate, and the leather to be trimmed is placed on the feed roller 51, and the feed roller 51 rotates to transport the leather to the conveyor belt 21 of the conveyor assembly 20; after the feed end 210 of the conveyor belt 21 receives the leather from the feed roller 51, it starts to move along the conveying direction and transports the leather to the discharge end 211; during the process of the leather being transported, the cutting drive 32 drives the blade 31 to move along the conveyor belt 211. 1 moves in a direction perpendicular to the conveying direction; since the blade 31 has the same conveying direction as the conveying direction of the conveyor belt 21, when the leather passes the position of the blade 31, the blade 31, under the action of the cutting drive 32, cuts and trims the edge of the leather to remove irregular parts of the leather edge; as the conveyor belt 21 continues to convey, the trimmed leather is conveyed to the discharge end 211; the discharge drive 42 drives the discharge roller 41 to rotate, and the discharge roller 41 collects the trimmed leather on the conveyor belt 21, completing the entire leather trimming process.
[0024] Compared with the prior art, in the leather trimming equipment of the present invention, the blade 31 in the cutting assembly 30 moves in a direction perpendicular to the conveying direction of the conveyor belt 21 under the control of the cutting drive 32, and can accurately and consistently cut the edge of the leather, ensuring the accuracy and quality of the trimming; the leather on the conveyor belt 21 runs stably during the transmission process, ensuring that the blade 31 accurately cuts the edge of the leather and improves the consistency of the trimming; the blade has the same transmission direction as the conveyor belt 21, which makes the cutting smoother and reduces the pulling and damage to the leather; the equipment has a high degree of automation, which greatly reduces the physical labor intensity of the workers; the workers only need to place the leather at the starting end of the equipment and collect the trimmed leather at the end end, without the need for heavy handling and manual cutting.
[0025] See also Figure 1 and Figure 2A pressing assembly 60 for pressing the leather surface is provided on the conveyor belt 21; the pressing assembly 60 includes a pressing bracket 61 installed on the conveyor belt 21, a movable part 62 installed on the pressing bracket 61, and a pressing member 63 installed on the movable part 62; the pressing member 63 is opposite to the conveyor belt 21. First, the clamping bracket 61 installed on the conveyor belt 21 provides a support structure for the entire clamping assembly 60; the movable part 62 on the clamping bracket 61 can be adjusted to a certain extent to adapt to leather of different thicknesses and different working conditions; as the conveyor belt 21 runs, when the leather passes under the clamping assembly 60, the movable part 62 drives the clamping part 63 to move toward the conveyor belt 21, so that the clamping part 63 is opposite to the conveyor belt 21 and gradually approaches the surface of the leather; the clamping part 63 applies a certain pressure on the leather surface, pressing the leather tightly against the conveyor belt 21; during the leather transmission process, the clamping part 63 can prevent the leather from warping, sliding and other unstable conditions, ensuring that the leather always remains flat on the conveyor belt 21, so that the cutting assembly 30 can trim the leather edge more accurately; at the same time, the pressure of the clamping part 63 also helps the leather to move stably on the conveyor belt 21, avoiding the impact of the trimming quality due to the shaking of the leather.
[0026] The leather trimming equipment also includes a fixing assembly, which includes a fixing cylinder 71 and a fixing member 72 installed on the clamping bracket 61. The fixing cylinder 71 includes a driving rod, and the fixing member 72 is connected to the end of the driving rod; the fixing surface of the fixing member 72 is set to match the side of the leather. First, the fixed cylinders 71 installed on both sides of the clamping bracket 61 are in a ready state; when the leather reaches the position of the fixing assembly, the fixed cylinder 71 is started and the drive rod begins to extend; the end of the drive rod is connected to the fixing part 72, and as the drive rod extends, the fixing part 72 approaches the side of the leather; the fixing surface of the fixing part 72 is matched with the side of the leather, and when the fixing part 72 contacts the side of the leather, it will fit tightly to the side of the leather; through the drive of the fixed cylinder 71, the fixing part 72 fixes the leather from both sides; in the process of trimming the leather, the role of the fixing part 72 is to further ensure the stability of the position of the leather on the conveyor belt 21 and prevent the leather from moving or shaking in the horizontal direction; working together with the clamping assembly 60, the clamping part 63 presses the leather from above, and the fixing part 72 fixes the leather from both sides, so that the leather is in a completely stable state on the conveyor belt 21, providing a reliable guarantee for the cutting assembly 30 to perform precise trimming operations.
[0027] The movable part 62 includes a pressing cylinder mounted on the pressing bracket 61, which includes a movable rod, and a pressing member 63 mounted at the end of the movable rod. When the equipment starts running, the leather is placed on the conveyor belt 21 for conveying and trimming operations; the pressing cylinder is mounted on the pressing bracket 61. When the leather needs to be compressed, the pressing member 63 is mounted at the end of the movable rod. As the movable rod extends, the pressing member 63 gradually approaches the leather on the conveyor belt 21; when the pressing member 63 contacts the surface of the leather, it continues to apply a certain amount of pressure, pressing the leather tightly against the conveyor belt 21; during the leather conveying and trimming process, the pressing cylinder can adjust the extension length of the movable rod according to actual conditions, thereby controlling the pressure of the pressing member 63 on the leather; this can adapt to leather of different thicknesses and different work requirements, ensuring that the leather always remains stable on the conveyor belt 21 so that the cutting assembly 30 can accurately trim the leather edge.
[0028] The pressing member 63 is an electric heating plate, and a first elastic member 64 is provided between the movable rod and the electric heating plate. In this embodiment, the first elastic member 64 is a rubber pad. The pressing cylinder is installed on the pressing bracket 61. When the equipment is running, it pushes the movable rod to extend; the movable rod is connected to the electric heating plate, and the movement of the movable rod drives the electric heating plate to move closer to the leather on the conveyor belt 21; the first elastic member 64 provided between the movable rod and the electric heating plate plays a role in buffering and regulating pressure; when the movable rod pushes the electric heating plate to contact the leather, the first elastic member 64 will compress or stretch according to the thickness and hardness of the leather, thereby adjusting the pressure of the electric heating plate on the leather, ensuring that the pressure is moderate, neither too light to cause the leather to be effectively pressed, nor too heavy to damage the leather; at the same time, the first elastic member 64 can also absorb a certain amount of vibration and impact force during the operation of the equipment, making the pressing process more stable. The electric hot press plays a dual role in the equipment; on the one hand, it acts as a pressing member 63 to press the leather to ensure the stability of the leather on the conveyor belt 21; on the other hand, it has a heating function; when the electric hot press comes into contact with the leather, heat is generated through the internal heating element and transferred to the leather; this heating effect can make the leather softer and easier to cut, improving the quality and accuracy of cutting; at the same time, for some leathers that need to be hot-pressed, the electric hot press can also perform hot-pressing processing while pressing, realizing the combination of multiple processes; during the heating process, the temperature of the electric hot press can be adjusted according to different leather materials and process requirements to achieve the best processing effect.
[0029] The leather trimming equipment also includes a printing component 80; the printing component 80 includes a printing bracket 81 installed on the conveyor belt 21, a printing cylinder 82 installed on the printing bracket 81 and a printing member 83 installed on the printing cylinder 82, the printing cylinder 82 includes a telescopic rod, and the printing member 83 is installed at the end of the telescopic rod; the printing surface of the printing member 83 is opposite to the conveyor belt 21. After the leather has completed the trimming operation on the conveyor belt 21, it continues to be conveyed and enters the working area of the printing assembly 80; the printing bracket 81 provides support for the printing cylinder 82 and the printing piece 83; when the leather needs to be printed, the printing cylinder 82 is started; the pressure inside the printing cylinder 82 causes the telescopic rod to extend; the printing piece 83 is installed at the end of the telescopic rod, and as the telescopic rod extends, the printing piece 83 gradually approaches the leather on the conveyor belt 21; when the printing surface of the printing piece 83 contacts the leather surface, the ink and other printing materials are transferred to the leather according to the pre-set pattern or text; during the printing process, the printing cylinder 82 can control the extension length and force of the telescopic rod, thereby adjusting the pressure of the printing piece 83 on the leather to ensure the clarity and quality of the printing; at the same time, the continuous transmission of the conveyor belt 21 can make the leather move smoothly under the printing piece 83, realizing continuous printing operation; through the printing assembly 80, personalized printing processing can be performed on the leather after trimming, increasing the added value and aesthetics of the leather products.
[0030] A second elastic member 84 is positioned between the telescopic rod and the printing element 83. This second elastic member 84 is made of silicone. When the printing cylinder 82 is activated, the telescopic rod begins to extend, pushing the printing element 83 toward the leather on the conveyor belt 21. As the telescopic rod pushes the printing element 83 into contact with the leather, the second silicone elastic member 84 begins to compress. Due to its excellent elasticity and cushioning properties, silicone acts as a buffer, preventing hard collisions between the printing element 83 and the leather, minimizing damage to both the leather and the printing element 83. Furthermore, the degree of compression of the second silicone elastic member 84 can be adjusted based on the thickness and hardness of the leather, ensuring that the printing element 83 exerts appropriate pressure on the leather, ensuring both print clarity and quality without damaging the leather due to excessive pressure. Furthermore, during the printing process, the conveyor belt 21 may experience minor unevenness, or the leather itself may have localized protrusions. The second silicone elastic member 84 adapts to these changes through its own elastic deformation, ensuring that the printing element 83 maintains good contact with the leather surface, thus ensuring continuous and stable printing.
[0031] A ball bearing structure 23 is provided on the conveyor belt 21 on one side of the discharge end 211. In this embodiment, the ball bearing structure 23 is composed of a plurality of freely rolling balls mounted on the surface of the conveyor belt 21. When the leather moves on the conveyor belt 21, the leather contacts the balls. Since the balls can roll freely, they can significantly reduce the friction between the leather and the conveyor belt 21. On the one hand, at the discharge end 211, the leather needs to be collected by the discharge roller 41 or proceed to the next step. The ball bearing structure 23 allows the leather to slide more smoothly on the conveyor belt 21, reducing problems such as leather jamming and pulling caused by excessive friction, ensuring that the leather can be smoothly transferred from the conveyor belt 21 to the discharge roller 41 or other subsequent processing equipment, thereby improving the continuity and efficiency of the entire production process. On the other hand, the ball bearing structure 23 can also reduce the wear of the leather during the conveyance process. Since the rolling friction between the leather and the balls is relatively small, the surface quality of the leather can be better protected compared to the traditional flat conveyor belt 21.
[0032] The above merely represents the preferred technical solution of the present invention. While the description is relatively specific and detailed, it should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the concept of the present invention, and the present invention is intended to encompass such modifications and variations.
