Description

Technical Field

[0001] The utility model belongs to the technical field of leather processing equipment, and particularly relates to a biodegradable semi-vegetable tanned leather embossing machine. Background Art

[0002] Biodegradable semi-vegetable-tanned leather requires embossing and laminating during production. Chinese patent publication number CN108728585A discloses an energy-efficient and efficient leather embossing machine, comprising a housing, a heat sink fixedly mounted on the inner top wall of the housing, a motor fixedly mounted at the bottom of the heat sink and within the housing, and limit frames fixedly mounted on both sides of the motor and at the bottom of the heat sink. This patent extends the life of the machine by fixing wear-resistant plates made of copper or steel in the gap formed by the transmission plate and the limit frame. The motor is installed inside the housing, allowing the machine to automatically press down, improving accuracy and avoiding human error. However, after embossing one piece of leather, it needs to be removed before the next piece can be embossed, preventing continuous embossing and resulting in low efficiency. Furthermore, only embossing is possible, not laminating, as laminating requires separate equipment, resulting in high costs and low production efficiency. Therefore, a biodegradable semi-vegetable-tanned leather embossing machine is needed to address the above-mentioned technical issues. Utility Model Content

[0003] In order to solve the above-mentioned defects in the prior art, the utility model provides a biodegradable semi-vegetable tanned leather embossing machine, comprising a frame, a belt conveyor 1 and a door-shaped cover are provided on the frame, the belt conveyor 1 passes through the door-shaped cover, an embossing roller cooperating with the belt conveyor 1 is provided in the door-shaped cover, a unwinding roller is provided at the feeding end of the door-shaped cover, and a winding roller is provided at the discharging end of the door-shaped cover, and the winding roller is connected to a winding motor; a transition roller, a flattening roller and a tensioning roller are provided in sequence in the door-shaped cover along the conveying direction of the belt conveyor 1, and the tensioning roller is arranged adjacent to the embossing roller;

[0004] The two ends of the flattening roller are rotatably connected to the two side walls of the door-shaped cover through bearings respectively. One end of the flattening roller passes through the door-shaped cover and is connected to a stepper motor 1. The stepper motor 1 is fixed on the outer wall of the door-shaped cover. The flattening roller is provided with a raised forward thread and a reverse thread, and the forward thread and the reverse thread are symmetrical about the center of the flattening roller. The film is wound around the unwinding roller. One end of the film passes through a transition roller, a flattening roller, a tensioning roller, and an embossing roller in sequence before being wound around the take-up roller. The film adheres to the film on its lower surface, which is contacted by the transition roller and tensioning roller, while the flattening roller and embossing roller contact the upper surface. As the film passes over the flattening roller, driven by stepper motor 1, the flattening roller rotates continuously, flattening the passing film to both sides under the action of the forward and reverse threads. After passing over the tensioning roller, the flattened film is pressed against the embossing roller, contacting the leather passing through it. The embossing roller applies the film to the leather, which is then reeled up by the take-up roller, completing the lamination and embossing operations. When lamination is not required, the film does not enter the door cover, and the embossing roller only embosses the leather passing through it. This reduces costs and improves production efficiency.

[0005] Preferably, the inner wall of the door-shaped cover corresponding to each end of the tensioning roller is provided with a slide groove, and a vertical electric push rod 1 is installed in each of the two slide grooves. The telescopic ends of the two electric push rods 1 are vertically upward and are respectively fixedly connected to a connecting block 1. The two connecting blocks 1 are respectively slidably arranged in the corresponding slide grooves, and the two ends of the tensioning roller are rotatably connected to the corresponding connecting block 1 via bearings. The height of the tensioning roller can be adjusted by retracting and retracting the electric push rod 1, thereby adjusting the tension of the passing membrane cloth.

[0006] Preferably, the feed end of the first belt conveyor is coupled with a second belt conveyor. The second belt conveyor is tilted, with the discharge end of the second belt conveyor lower than the feed end of the second belt conveyor. The feed end of the second belt conveyor is provided with a press roller, both ends of which are rotatably connected to a second connecting block via bearings. One end of the press roller passes through the second connecting block and is connected to a first rotating motor. The first rotating motor is fixed to the second connecting block. Two second connecting blocks are respectively fixedly connected to two electric push rods, which are respectively fixed to both sides of the second belt conveyor. This arrangement allows for pre-processing of the leather entering the first belt conveyor, such as manual flattening, to make subsequent lamination and embossing more accurate and efficient.

[0007] Preferably, the feeding end of the belt conveyor 1 is provided with a cleaning roller, and the cleaning roller is connected to a stepper motor 2. This arrangement can remove dust from the leather and improve the quality of subsequent lamination and embossing.

[0008] Preferably, the embossing roller includes a roller body, both ends of which are detachably connected to a rotating shaft via connecting bolts, the other ends of the two rotating shafts being rotatably connected to a connecting block three via bearings, the side walls of the door-shaped covers corresponding to the two connecting blocks three being provided with vertical long strip through-slots, the connecting blocks three being slidably arranged in the corresponding long strip through-slots, the two long strip through-slots being fixed with vertical electric push rods three, the telescopic ends of the two electric push rods three being fixedly connected to the corresponding connecting blocks three, one of the rotating shafts passing through the connecting block three being connected to a rotating motor two, the rotating motor two being fixed to the connecting block three, the roller body being provided with an embossing cylinder, the embossing cylinder being detachably connected to the roller body via countersunk bolts. This arrangement allows the embossing cylinder to be removed or replaced as needed. When only lamination is required, the roller body is not provided with the embossing cylinder, and the roller body covers the film on the leather.

[0018] The present invention is described below in conjunction with the accompanying drawings and specific embodiments of the present invention. The description herein is intended only to explain the present invention and is not intended to limit the present invention. Based on the embodiments of the present invention, any modifications, equivalent substitutions, improvements, etc. made by those skilled in the art without creative work to all other embodiments obtained based on the embodiments of the present invention shall be included within the scope of protection of the present invention.

[0019] Example

[0020] like Figure 1-5 As shown, the utility model provides an embossing machine for biodegradable semi-vegetable tanned leather 15, comprising a frame 1, a belt conveyor 1 and a door-shaped cover 2 provided on the frame 1, the belt conveyor 1 passing through the door-shaped cover 2, an embossing roller cooperating with the belt conveyor 1 provided in the door-shaped cover 2, a unwinding roller 3 provided at the feeding end of the door-shaped cover 2, a winding roller 4 provided at the discharging end of the door-shaped cover 2, and the winding roller 4 connected to a winding motor; a transition roller 10, a flattening roller 11 and a tensioning roller 13 are sequentially provided in the door-shaped cover 2 along the conveying direction of the belt conveyor 1, and the tensioning roller 13 is arranged adjacent to the embossing roller;

[0021] The two ends of the flattening roller 11 are rotatably connected to the two side walls of the door-shaped cover 2 through bearings respectively. One end of the flattening roller 11 passes through the door-shaped cover 2 and is connected to a stepper motor 16. The stepper motor 16 is fixed on the outer wall of the door-shaped cover 2. The flattening roller 11 is provided with a raised forward thread 12 and a reverse thread. The forward thread 12 and the reverse thread are symmetrical about the center of the flattening roller 11. The membrane cloth 9 is wound on the unwinding roller 3, and one end of the membrane cloth 9 passes through the transition roller 10, flattening roller 11, tensioning roller 13, and embossing roller in sequence and is then wound on the winding roller 4. The film adhered to the membrane cloth 9 is located on the lower surface of the membrane cloth 9, and the transition roller 10 and tensioning roller 13 are in contact with the lower surface of the membrane cloth 9, and the flattening roller 11 and embossing roller are in contact with the upper surface of the membrane cloth 9. When the membrane cloth 9 passes through the flattening roller 11, the flattening roller 11 rotates continuously under the drive of the stepping motor 16. Under the action of the forward thread 12 and the reverse thread, the passing membrane cloth 9 is flattened to both sides. After passing through the tensioning roller 13, the flattened membrane cloth 9 is pressed by the embossing roller and contacts the leather 15 passing through the embossing roller. Under the action of the embossing roller, the film is covered on the leather 15, and then the membrane cloth 9 is wound up by the winding roller 4 to complete the lamination and embossing operations. When lamination is not required, the film cloth 9 does not enter the door-shaped cover 2, and the embossing roller only performs embossing operation on the leather 15 passing through, thereby reducing costs and improving production efficiency.

[0022] The tensioning roller 13 has two ends, each of which is provided with a chute on the inner wall of the door-shaped cover 2. A vertical electric push rod 17 is installed in each of the two chute. The telescopic ends of the two electric push rods 17 are vertically upward and fixedly connected to a connecting block 18. The two connecting blocks 18 are slidably arranged in the corresponding chute. The two ends of the tensioning roller 13 are rotatably connected to the corresponding connecting block 18 via bearings. The height of the tensioning roller 13 can be adjusted by extending and retracting the electric push rod 17, thereby adjusting the tension of the passing membrane cloth 9.

[0023] The feed end of the belt conveyor 1 is equipped with a belt conveyor 2 5. The belt conveyor 2 5 is tilted, and the discharge end of the belt conveyor 2 5 is lower than the feed end of the belt conveyor 2 5. The feed end of the belt conveyor 2 5 is provided with a pressing roller 6. The two ends of the pressing roller 6 are rotatably connected to the connecting block 2 via bearings. One end of the pressing roller 6 passes through the connecting block 2 and is connected to the rotating motor 1. The rotating motor 1 is fixed to the connecting block 2. The two connecting blocks 2 are respectively fixedly connected to the electric push rods 2 7. The two electric push rods 2 7 are respectively fixed to the two sides of the belt conveyor 2 5. This arrangement can pre-process the leather 15 entering the belt conveyor 1, such as performing a manual flattening operation, so that the subsequent lamination and embossing are more accurate and efficient.

[0024] The feed end of the belt conveyor 1 is provided with a cleaning roller 8, which is connected to a stepper motor 2. This arrangement can remove dust from the leather 15 to improve the quality of subsequent lamination and embossing.

[0025] The embossing roller includes a roller body, wherein both ends of the roller body are respectively connected to a rotating shaft 19, one end of the two rotating shafts 19 is fixedly connected to a connecting piece 14, and the connecting piece 14 is detachably connected to the end of the corresponding roller body through a connecting bolt 22, and the other ends of the two rotating shafts 19 are rotatably connected to a connecting block three 23 through a bearing, and the side walls of the door-shaped cover 2 corresponding to the two connecting blocks three 23 are provided with a vertical long strip through groove, and the connecting block three 23 is slidably set in the corresponding long strip through groove, and a vertical electric push rod three 24 is fixed in the two long strip through grooves, and the telescopic ends of the two electric push rods three 24 are respectively fixedly connected to the corresponding connecting block three 23, one of the rotating shafts 19 passes through the connecting block three 23 and is connected to a rotating motor two 25, and the rotating motor two 25 is fixed on the connecting block three 23, and an embossing cylinder 20 is sleeved on the roller body, and the embossing cylinder 20 is detachably connected to the roller body by a countersunk bolt 21. The roller is an electrically heated roller. The contact surface between the roller and the connecting piece is equipped with cooperating conductive blocks (conductive contacts). The conductive blocks on the connecting piece are connected to an external power source via a conductive slip ring. When the electrically heated roller is powered, it heats the embossing cylinder, enhancing the embossing effect. The embossing cylinder 20 can be removed or replaced as needed. When only lamination is required, the roller is not fitted with the embossing cylinder 20, and the roller applies the film to the leather 15.

[0026] Working principle: The leather to be processed is placed on belt conveyor 2 in sequence. After pre-sorting (flattening and dust removal with a cleaning brush), it enters belt conveyor 1 and is transported to the door cover in sequence. After passing through the embossing roller, it undergoes embossing, laminating, or embossing-laminating operations. Specifically, when only embossing is required, the film cloth 9 does not enter the door cover 2, and the embossing roller only embosses the leather 15 passing through it. When laminating is required only, the roller body is not equipped with an embossing cylinder 20, and the roller body covers the film on the leather 15 to complete the laminating operation. When laminating and embossing are performed simultaneously, the film cloth enters the door cover and is flattened by the flattening roller. Then, the film cloth 9 passes through the tensioning roller 13 and is pressed by the embossing roller to contact the leather 15 passing through the embossing roller. Under the action of the embossing roller, the film is covered on the leather 15. Then, the film cloth 9 is wound up by the winding roller 4, completing the laminating and embossing operations.

[0027] While the embodiments of the present invention have been described above, the foregoing description is intended to be illustrative, non-exhaustive, and not limited to the disclosed embodiments. Numerous modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention are intended to be included within the scope of protection of the present invention.
