Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0027] Embodiments of this utility model:

[0028] like Figure 1 and 2 As shown: A scrap leather cleaning machine includes a frame 1 and a conveying mechanism 2 installed on the frame 1 (both the frame 1 and the conveying mechanism 2 are prior art and will not be described in detail in this application); a centering mechanism 3 and a material blocking mechanism 4 are installed on the upper part of the frame 1, and the centering mechanism 3 is set near the feed inlet of the conveying mechanism 2. The centering mechanism 3 can be used to collect and clean scrap leather 5; the material blocking mechanism 4 can block the scrap leather 5, making it convenient to collect the scrap leather 5.

[0029] like Figure 3 and 4As shown: The centering mechanism 3 includes two parallel mounting seats 31, which are fixed to the top sides of the frame 1. A bidirectional lead screw 32 is rotatably mounted between the two mounting seats 31. One end of the bidirectional lead screw 32 passes through the mounting seat 31 and is fitted with a drive structure 33, which drives the bidirectional lead screw 32. Two movable frames 34 are threaded onto both ends of the bidirectional lead screw 32, allowing them to move in opposite directions. A scrubbing brush 35 is rotatably mounted on the bottom of the movable frame 34, which centers the scrap material 5 on the conveying mechanism 2. It should be noted that parallel first guide rods 311 are symmetrically mounted between the two mounting seats 31 about the bidirectional lead screw 32, and the two sides of the movable frame 34 are slidably mounted on the first guide rods 311. The first guide rods 311 limit the movement of the movable frame 34, preventing it from wobbling during movement.

[0030] like Figure 3 As shown in Figure 4: Each movable frame 34 is equipped with a second motor 36, and the output end of the second motor 36 is equipped with a second drive wheel 37. One end of the scrubbing brush 35 is equipped with a second driven wheel 38, and the second drive wheel 37 and the second driven wheel 38 are arranged on the same side. The second drive wheel 37 and the second driven wheel 38 are connected by a second conveyor belt 39 for transmission, which can drive the scrubbing brush 35 to rotate at high speed and clean the scraps 5. It should be noted that a protective cover 310 is installed on one side of the movable frame 34, and the second conveyor belt 39 is located inside the protective cover 310. The protective cover 310 serves to protect the second conveyor belt 39.

[0031] like Figure 3 As shown in Figure 4: Specifically, the drive structure 33 includes a first mounting plate 331 mounted on one side of one of the mounting bases 31, and a first motor 332 is mounted on the top of the first mounting plate 331. It should be noted that the first motor 332 is a servo motor. The output shaft of the first motor 332 is equipped with a first drive wheel 333, and one end of the bidirectional lead screw 32 is equipped with a first driven wheel 334. The first drive wheel 333 and the first driven wheel 334 are connected by a first conveyor belt 335. Through the setting of the drive structure 33, the bidirectional lead screw 32 is driven.

[0032] like Figure 5 and 6As shown: The material blocking mechanism 4 includes a top plate 41 mounted on the frame 1, and a cylinder 42 is mounted on the lower part of the top plate 41. A baffle 43 is mounted on the bottom end of the cylinder 42. The baffle 43 serves to block the scrap material 5, facilitating the centering of the scrap material 5. It should be noted that: two ends of the baffle 43 are respectively fixed with sliding cylinders 44, and the two sliding cylinders 44 are slidably mounted on the second guide rods 45. The second guide rods 45 serve to limit the position of the baffle 43. The bottom ends of the two second guide rods 45 are fixedly connected to the same fixed seat 46, and the fixed seat... Mounting plate 46 is also mounted on frame 1. It should be noted that: a second mounting plate 47 is mounted on mounting plate 46, and a distance sensor 48 for monitoring baffle 43 is mounted on the second mounting plate 47. The output end of distance sensor 48 is electrically connected to controller (not shown in the figure) via a wire. The output end of controller is electrically connected to cylinder 42 via a wire. If the distance that baffle 43 moves downward reaches the set value of distance sensor 48, distance sensor 48 can transmit a signal to controller, and controller controls cylinder 42 to prevent cylinder 42 from continuously driving baffle 43 to move downward.

[0033] When cleaning scrap material 5, first place scrap material 5 on conveying mechanism 2 with its curved surface facing upwards. As conveying mechanism 2 continuously conveys scrap material 5, when scrap material 5 is conveyed to a position close to the blocking mechanism 4, the telescopic end of cylinder 42 extends and drives baffle 43 to move downwards, blocking scrap material 5. Then, the first motor 332 and the second motor 36 are activated simultaneously. The output end of the first motor 332 drives the first drive wheel 333 to rotate. The first drive wheel 333 drives the first driven wheel 334 to rotate via the first conveyor belt 335. The first driven wheel 334 rotates the bidirectional screw 32. The bidirectional screw 32 rotates during the rotation process. During the process, the two moving frames 34 can be moved towards the middle part; during the movement of the moving frames 34, the scrubbing brushes 35 can also be moved, and the two scrubbing brushes 35 can be used to center the scrap material 5; the second motor 36 can drive the second drive wheel 37 to rotate, and the second drive wheel 37 drives the second driven wheel 38 to rotate through the second conveyor belt 39, and the second driven wheel 38 drives the scrubbing brushes 35 to rotate. During the rotation of the scrubbing brushes 35, the edges of the scrap material 5 can be cleaned. After the scrap material 5 is cleaned, the cylinder 42 drives the baffle 43 to move upward, and the scrap material 5 loses its obstruction. The scrap material 5 is continuously conveyed by the conveying mechanism 2 and further processed.
