Description

Technical Field

[0001] This application relates to the field of leather production technology, specifically to an embossing correction device and leather production equipment. Background Technology

[0002] Leather is animal hide that has undergone physical and chemical processing such as hair removal and tanning, resulting in a modified, less perishable material. It is composed of tightly woven natural protein fibers in three dimensions, with a unique grain layer on its surface that gives it a natural grain and luster, and a comfortable feel. During leather production, embossing is performed on the leather according to the specific pattern requirements.

[0003] Traditional embossing devices typically use embossing rollers and felt belts to emboss the leather as it passes over the rollers. In leather production, multiple processes are usually carried out consecutively, and the embossing process is no exception. As one piece of leather is embossed, the next piece simultaneously enters the embossing device, which operates continuously. Over time, the felt belt can easily become misaligned due to the force of the leather, affecting subsequent embossing processes. Utility Model Content

[0004] This application provides an embossing correction device and leather production equipment to improve the problem of felt belt misalignment in the embossing device.

[0007] Optionally, the correction drive assembly includes a fixed frame, a guide rod, and a movable hydraulic cylinder. The guide rod is fixed to the fixed frame and passes through the movable hydraulic cylinder to define two hydraulic chambers separated from each other within the movable hydraulic cylinder. The top of the movable hydraulic cylinder has two inlet holes, which are connected to the hydraulic chambers one by one.

[0008] Optionally, the offset detection component includes a fixed post, a connecting plate, a support plate, a first limit switch, and a lever. The fixed post is fixed to the correction drive component. One end of the connecting plate is detachably connected to the fixed post, and the other end is connected to the first limit switch. The support plate is connected to the correction drive component and the connecting plate to support the connecting plate. The lever is signal-connected to the first limit switch, and one end of the lever away from the first limit switch extends to one side of the felt belt and is spaced apart from the felt belt.

[0009] Optionally, the connecting plate has a waist-shaped hole, and the support plate is connected to the connecting plate by bolts passing through the waist-shaped hole.

[0010] Optionally, the felt drive mechanism includes a first motor, a first reducer, a first chain, a first drive sprocket, a first driven sprocket, a first felt roller, and a second felt roller.

[0011] Optionally, the embossing correction device further includes a lifting hydraulic cylinder, the lifting drive end of which is located below the first felt roller and connected to the first felt roller.

[0012] Optionally, the embossing correction device further includes a leather feeding mechanism, a leather pressing mechanism, and a leather driving mechanism. The driving end of the leather driving mechanism is connected to both the leather feeding mechanism and the leather pressing mechanism. The leather feeding mechanism and the leather pressing mechanism are arranged sequentially along the leather conveying direction, with the leather feeding mechanism located above the leather pressing mechanism and spaced apart to form a leather conveying gap.

[0013] Optionally, the embossing correction device further includes an anti-jamming detection plate and a second limit switch. The anti-jamming detection plate is hinged to the main frame and located above the leather feeding and conveying mechanism, forming a leather input gap for the leather to pass through. The second limit switch is located on one side of the anti-jamming detection plate along the leather conveying direction and on the path of movement of the anti-jamming detection plate.

[0015] Therefore, the embodiments of this application utilize the correction side of the correction mechanism to abut against the felt belt and use the correction side to perform reciprocating motion to correct the position of the felt belt.

Specifically, firstly, the felt belt is driven by a felt drive mechanism to circulate, ensuring stable conveying of the leather on the felt belt. When the leather reaches the embossing gap, the embossing roller can perform the embossing operation on the leather. When the felt belt deviates, the correction side of the correction mechanism will reciprocate along the direction of leather conveying, using the friction between the correction side and the felt belt to adjust the position of the felt belt until it returns to its original position.

Detailed Implementation

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or specifying the number of technical features indicated. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0021] Please see Figures 1 to 9This application provides an embossing correction device, including a main frame 1, a felt drive mechanism 2, a felt belt 3, an embossing roller 4, and a correction mechanism 5. The felt drive mechanism 2 is located on the main frame 1. The felt belt 3 is located on the drive side of the felt drive mechanism 2, enabling the felt belt 3 to form a closed-loop cyclic motion. The embossing roller 4 is located on the main frame 1 and above the felt belt 3, spaced apart from the felt belt 3 to form an embossing gap for leather to pass through. The correction mechanism 5 is located on the main frame 1, with its correction side located below and abutting against the felt belt 3. The correction side can reciprocate along the leather conveying direction to correct the position of the felt belt 3.

[0022] The technical solution of this application utilizes the correction side of the correction mechanism 5 to abut against the felt belt 3 and uses the correction side to perform reciprocating motion to correct the position of the felt belt 3. This correction process can be performed during the embossing process, that is, during the leather conveying process, the correction mechanism 5 can work synchronously, enabling the embossing correction device to adjust the position of the felt belt 3 in real time while minimizing downtime, maintaining the continuity of the embossing process and improving efficiency. Specifically, firstly, the felt drive mechanism 2 drives the felt belt 3 to circulate, ensuring stable conveying of the leather on the felt belt 3. When the leather reaches the embossing gap, the embossing roller 4 can perform the embossing work on the leather. When the felt belt 3 deviates, the correction side of the correction mechanism 5 will reciprocate along the direction of leather conveying, using the friction between the correction side and the felt belt 3 to adjust the position of the felt belt 3 until it returns to its original position.

[0023] In some embodiments, see Figures 4 to 7 The correction mechanism 5 includes a correction drive assembly 51, a correction roller 52, and a deviation detection assembly 53. The drive end of the correction drive assembly 51 can reciprocate along the leather conveying direction and is fixedly connected to one end of the correction roller 52. The end of the correction roller 52 away from the correction drive assembly 51 is connected to the main frame 1. The deviation detection assembly 53 is connected to the correction drive assembly 51, and the detection end of the deviation detection assembly 53 is located on the side of the felt belt 3 and spaced apart. The deviation detection assembly 53 is signal-connected to the correction drive assembly 51. When the deviation detection assembly 53 detects that the felt belt 3 has deviated, it sends a signal to the correction drive assembly 51 indicating that the felt belt 3 has deviated. After receiving the signal, the correction drive assembly 51 starts to drive the correction roller 52 to reciprocate along the leather conveying direction, thereby gradually bringing the deviated felt belt 3 back to its original position.

[0024] Further, please see Figure 5 and Figure 6The correction drive assembly 51 includes a fixed frame 511, a guide rod 512, and a movable hydraulic cylinder 513. The guide rod 512 is fixed to the fixed frame 511 and passes through the movable hydraulic cylinder 513 to define two mutually separated hydraulic chambers 5132 within the movable hydraulic cylinder 513. The movable hydraulic cylinder 513 has two fluid inlet holes 5131 at its top, and each fluid inlet hole 5131 communicates with one of the hydraulic chambers 5132. In this embodiment, the movable hydraulic cylinder 513 is a movable oil cylinder, and the fluid is oil. When oil is introduced into one of the inlet holes 5131, the pressure of the oil will act on the movable hydraulic cylinder 513. Since the guide rod 512 is fixed, the movable hydraulic cylinder 513 itself acts as the piston for the movement of the hydraulic cylinder, allowing the movable hydraulic cylinder 513 to move along the axial direction of the guide rod 512. Since the movable hydraulic cylinder 513 is connected to the straightening roller 52, it drives one end of the straightening roller 52 to reciprocate, so that the felt belt 3 on the straightening roller 52 can be rubbed back into place by the reciprocating movement of the straightening roller 52.

[0025] In some embodiments, see Figure 7 The offset detection component 53 includes a fixed post 531, a connecting plate 532, a support plate 533, a first limit switch 534, and a lever 535. The fixed post 531 is fixed to the correction drive component 51. One end of the connecting plate 532 is detachably connected to the fixed post 531, and the other end is connected to the first limit switch 534. The support plate 533 is connected to the correction drive component 51 and also to the connecting plate 532 to support the connecting plate 532. The lever 535 is signal-connected to the first limit switch 534, and one end of the lever 535 away from the first limit switch 534 extends to one side of the felt belt 3 and is spaced apart from the felt belt 3. When the felt belt 3 offsets to a certain amount, the felt belt 3 will contact and abut against the lever 535. At this time, the lever 535 will trigger the first limit switch 534, causing the first limit switch 534 to open, which is equivalent to detecting the offset of the felt belt 3. Furthermore, the opening of the first limit switch 534 will drive the correction drive component 51 to open, thereby causing the correction drive component 51 to drive the felt roller to reciprocate back and forth, relying on the friction between the felt roller and the felt belt 3 to bring the felt belt 3 back to its original position.

[0026] Furthermore, the connecting plate 532 has a slotted hole 5321, and the support plate 533 and the connecting plate 532 are connected by bolts passing through the slotted hole 5321. By utilizing the slotted hole 5321, the position of the bolt connection can be selected according to the actual situation, which generally refers to the width of the felt belt 3. That is, the operator can adjust the connection position of the support plate 533 and the connecting plate 532 at the slotted hole 5321 according to the width of the felt belt 3, thereby adjusting the position of the lever 535 to ensure that the lever 535 can always be spaced apart from the side of the felt belt 3 at the beginning, and even the distance of the gap can be determined by adjustment.

[0027] In some embodiments, see Figure 3 The felt drive mechanism 2 includes a first motor 21, a first reducer 22, a first chain 23, a first drive sprocket 24, a first driven sprocket 25, a first felt roller 26, and a second felt roller 27. The output end of the first motor 21 is connected to the first reducer 22, and the first drive sprocket 24 is connected to the output end of the first reducer 22. The first drive sprocket 24 is connected to the first driven sprocket 25 via the first chain 23. The first driven sprocket 25 is connected to the first felt roller 26, and the second felt roller 27 is connected to the first felt roller 26 via a felt belt 3. When the first motor 21 starts, the speed is reduced by the first reducer 22, and the reduced rotational motion is transmitted to the drive sprocket for easier control of the drive sprocket's speed. The rotation of the drive sprocket drives the driven sprocket to rotate via the first chain 23. The rotation of the driven sprocket drives the first felt roller 26 to rotate. The rotation of the first felt roller 26 causes the felt belt 3 laid on the first felt roller 26 to move. The movement of the felt belt 3 synchronously drives the second felt roller 27 to rotate, thereby causing the felt belt 3, which is sleeved on the first felt roller 26 and the second felt roller 27, to circulate. After the leather is conveyed onto the felt belt 3, the felt belt 3 will convey the leather to the embossing roller 4 for embossing.

[0028] Further, please see Figure 2 The embossing correction device also includes a lifting hydraulic cylinder 6. The lifting drive end of the lifting hydraulic cylinder 6 is located below and connected to the first felt roller 26. By using the lifting hydraulic cylinder 6 to drive the first felt roller 26 to rise and fall, the gap between the first felt roller 26 and the embossing roller 4 is changed, thereby squeezing the leather located in the embossing gap by the embossing roller 4, thus completing the embossing process. The lifting hydraulic cylinder 6 can be a pneumatic cylinder or a hydraulic cylinder.

[0029] In some embodiments, see Figure 8 and Figure 9The embossing and correction device also includes a leather feeding conveyor 7, a leather pressing conveyor 8, and a leather driving mechanism 9. The driving end of the leather driving mechanism 9 is connected to both the leather feeding conveyor 7 and the leather pressing conveyor 8. The leather feeding conveyor 7 and the leather pressing conveyor 8 are arranged sequentially along the leather conveying direction, with the leather feeding conveyor 7 positioned above the leather pressing conveyor 8 and spaced apart to form a leather conveying gap. When the leather is conveyed to the leather feeding conveyor 7, it receives the leather and continues to convey it to the position between the leather pressing conveyor 8 and the leather feeding conveyor 7. At this point, the leather is squeezed by the leather feeding conveyor 7 and the leather pressing conveyor 8 to ensure that the leather remains as flat as possible, preventing severe wrinkles or curling at the other end of the leather when one end is embossed. After passing under the leather pressing conveyor 8, the leather falls onto the felt belt 3 and is transported by the felt belt 3 to the area below the embossing roller 4.

[0030] Further, please see Figure 7 The leather drive mechanism 9 includes a second motor 91, a second reducer 92, a second drive sprocket 93, a second driven sprocket 94, a third driven sprocket 95, a first tension sprocket 96, a second tension sprocket 97, and a second chain 98. The output end of the second motor 91 is connected to the second reducer 92, and the output end of the second reducer 92 is connected to the second drive sprocket 93, so that the rotational motion after being reduced by the second reducer 92 is transmitted to the second drive sprocket 93. The second drive sprocket 93 meshes with the inner side of the second chain 98, the outer side of the second chain 98 meshes with the second driven sprocket 94, and the inner side of the second chain 98 also meshes with the third driven sprocket 95, the first tension sprocket 96, and the second tension sprocket 97. Furthermore, along the leather conveying direction, the third driven sprocket 95, the first tensioning sprocket 96, the second driven sprocket 94, and the second driving sprocket 93 are arranged sequentially, with the second tensioning sprocket 97 and the first tensioning sprocket 96 arranged opposite each other in the vertical direction. The second driven sprocket 94 is connected to the pressing conveyor 8, and the third driven sprocket 95 is connected to the feeding conveyor 7. This allows the rotation of the second driving sprocket 93 to be transmitted to the second driven sprocket 94 and the third driven sprocket 95 via the second chain 98, thereby driving the second driven sprocket 94 and the third driven sprocket 95 to rotate. This achieves synchronous movement of the feeding conveyor 7 and the pressing conveyor 8 using only one second motor 91.

[0031] It should be noted that by placing the second driven sprocket 94 on the outside of the second chain 98 and the third driven sprocket 95 on the inside of the second chain 98, the synchronous rotation directions of the second driven sprocket 94 and the third driven sprocket 95 are opposite. Furthermore, because the pressing transmission mechanism 8 is located above the feeding transmission mechanism 7, the pressing transmission mechanism 8 and the feeding transmission mechanism 7 can transport leather in the same direction.

[0032] In some embodiments, see Figure 8 and Figure 9 The leather feeding and conveying mechanism 7 includes a leather feeding drive roller 71, a leather feeding conveyor belt 72, and a leather feeding driven roller 73. The leather feeding drive roller 71 is connected to a third driven sprocket 95. The leather feeding conveyor belt 72 is fitted onto the leather feeding drive roller 71 and is connected to the leather feeding driven roller 73 by means of the leather feeding conveyor belt 72. The leather feeding driven roller 73 is arranged opposite to the leather feeding drive roller 71.

[0033] In some embodiments, see Figure 7 The pressing and conveying mechanism 8 includes a pressing drive roller 81, a pressing conveyor belt 82, and a pressing driven roller 83. The pressing drive roller 81 is connected to a second driven sprocket 94. The pressing conveyor belt 82 is fitted onto the pressing drive roller 81 and is connected to the pressing driven roller 83 via the pressing conveyor belt 82. The pressing driven roller 83 is arranged opposite to the pressing drive roller 81. The pressing conveyor belt 82 is located above the feeding conveyor belt 72 to form a leather conveying gap. Because the second driven sprocket 94 is located outside the second chain 98 and the third driven sprocket 95 is located inside the second chain 98, the synchronous rotation directions of the second driven sprocket 94 and the third driven sprocket 95 are opposite. Because the pressing conveyor belt 82 is located above the feeding conveyor belt 72, the pressing conveyor belt 82 and the feeding conveyor belt 72 can convey leather in the same direction.

[0034] In some embodiments, see Figure 1 , Figure 8 and Figure 9 The embossing correction device also includes an anti-jamming detection plate 10 and a second limit switch 20. The anti-jamming detection plate 10 is hinged to the main frame 1 and located above the leather feeding mechanism 7, forming a leather input gap for the leather to pass through. The second limit switch 20 is located on one side of the anti-jamming detection plate 10 along the leather feeding direction and on the path of the anti-jamming detection plate 10's movement. When the thickness of the leather is less than or equal to the leather input gap, the leather will pass smoothly through the leather input gap via the leather feeding mechanism 7 without triggering the second limit switch 20, and the embossing correction device will operate normally. When the thickness of the leather is greater than the leather input gap, a portion of the leather will impact the anti-jamming detection plate 10. The hinged connection of the anti-jamming detection plate 10 causes it to rotate around the hinge axis toward the second limit switch 20 until it touches the second limit switch 20. The second limit switch 20 will then issue a stop signal, and all electrically controlled equipment in the embossing correction device will stop, preventing excessively thick leather from damaging the device or producing leather that does not meet the thickness requirements.

[0035] In some embodiments, the embossing correction device includes an electrical control cabinet 30 and a hydraulic control cabinet 40. The electrical control cabinet 30 is electrically connected to the felt drive mechanism 2, the correction mechanism 5, and the leather drive mechanism 9 to achieve automated control of the embossing correction device. The hydraulic control cabinet 40 is connected to the lifting hydraulic cylinder 6 and the correction drive component 51 in the correction mechanism 5 to provide hydraulic power to the correction drive component 51 and the lifting hydraulic cylinder 6. The hydraulic power can be hydraulic oil.

[0036] Embodiments of this application also provide a leather production apparatus, including the embossing and correction device described in any of the foregoing embodiments. Since the leather production apparatus has an embossing and correction device, the structure and beneficial effects of such a device are inherent in the leather production apparatus and will not be elaborated further here.
