Description

Technical Field

[0001] This utility model relates to the field of leather manufacturing technology, specifically a leather rubbing machine for leather manufacturing. Background Technology

[0002] Leather is animal skin that has undergone tanning. Through physical and chemical processes such as hair removal and tanning, it is transformed into a durable and flexible material, widely used in fashion, home furnishings, and industry. Leather is made from animal hides (such as cows, sheep, and pigs) through tanning, and its origins can be traced back to the Upper Cave Man period, when it was used to sew clothing for warmth. The modern leather industry encompasses tanning, shoemaking, and leather clothing, with China being the world's largest producer. Leather is widely used in: Fashion: luxury goods (such as Hermès crocodile Birkin bags), everyday clothing (leather clothing and shoes); Home furnishings and industry: sofas, car interiors, machine tires; Culture and defense: genuine leather soccer balls, python skin harp leather, and fire-resistant combat boots. In the leather manufacturing process, the rubbing machine (also known as a leather rubbing machine or leather folding machine) is a key post-processing device. Its core function is to optimize the physical properties and appearance of the leather through mechanical rubbing, stretching, and compression, laying the foundation for subsequent processing (such as coating, cutting, and sewing).

[0003] Existing technologies, traditional leather texturing machines suffer from two prominent structural design problems: First, the texturing cylinder lacks an efficient cooling mechanism. During the texturing process, the friction between the leather and the cylinder wall generates a large amount of heat, and existing equipment mostly relies on natural heat dissipation or simple air cooling, making it impossible to control the temperature in real time. This leads to quality defects in the leather due to localized overheating, such as fiber hardening, uneven color, and even surface cracking. Second, the alignment precision of the cooling medium delivery pipes is insufficient. After the texturing cylinder stops rotating, the positions of the inlet and outlet pipes, and the drain and guide pipes, often become misaligned. Traditional equipment, relying solely on fixed supports or manual calibration, cannot guarantee precise alignment, which not only increases the risk of cooling medium leakage but also affects the consistency of the texturing effect due to interrupted cooling circulation, severely restricting production stability and operational safety. Therefore, a leather texturing machine for leather manufacturing is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a leather rubbing machine for leather manufacturing, which solves the technical problem that the rubbing cylinder lacks an efficient cooling mechanism and generates a large amount of heat due to friction between the leather and the cylinder wall during the rubbing process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a leather rubbing machine for leather manufacturing, comprising:

[0006] The support base includes outer frame plates on both sides of the upper surface of the support base. A first drive motor is installed on the outer side of the outer frame plate, and a kneading cylinder is added between adjacent outer frame plates. The first drive motor is coaxially connected to the kneading cylinder, and an opening and closing outer plate is rotatably connected to the inlet and outlet of the kneading cylinder. A cooling pipe is provided on the inner wall of the kneading cylinder, and an inlet pipe and an outlet pipe are respectively added to the upper surface and the back of the kneading cylinder. The inlet pipe and the outlet pipe are respectively connected to the water inlet end and the water outlet end of the cooling pipe. A positioning horizontal plate is installed at the center of the back of the kneading cylinder, and a positioning vertical plate is rotatably connected to the back of the support base. A second drive motor is coaxially connected to the rotating end of the positioning vertical plate, and the upper surface of the positioning vertical plate is in contact with the lower surface of the positioning horizontal plate.

[0007] The outlet pipe is located directly above the inlet pipe, and a guide pipe is added to the outer end of the outlet pipe. A fixing seat is installed on the surface of the outlet pipe and the guide pipe, and the fixing seat is connected to the outer frame plate. An electric telescopic rod is installed on the surface of the fixing seat, and the telescopic end of the electric telescopic rod is connected to the corresponding outlet pipe and guide pipe respectively. A solenoid valve is installed on the surface of the inlet pipe and the guide pipe.

[0008] The infusion pump and circulation pump are connected to their respective inlet pipes and guide pipes, and both the infusion pump and circulation pump are connected to a cooling water tank, which is connected to the outer frame plate.

[0009] Open the outer panel and put the leather to be processed into the rubbing cylinder. Then close the outer panel and start the second drive motor, which drives the positioning vertical plate to rotate around the back of the support base, so that the upper surface of the positioning vertical plate separates from the lower surface of the positioning horizontal plate.

[0010] The first drive motor is started, which drives the rubbing cylinder to rotate between the outer frame plates to rub the inner leather. The rubbing cylinder is a common and technologically mature device on the market, so it will not be described in detail here.

[0011] After the kneading operation is completed, the first drive motor is turned off, the kneading cylinder stops rotating, and the second drive motor is started to drive the positioning vertical plate to align and fit with the positioning horizontal plate, so that the liquid inlet pipe corresponds to the liquid outlet pipe and the liquid drain pipe corresponds to the liquid guide pipe.

[0012] The electric telescopic rod on the surface of the control base extends, which pushes the liquid outlet pipe to connect with the liquid inlet pipe and the liquid guide pipe to connect with the liquid drain pipe respectively. After the connection is completed, the electric telescopic rod is closed.

[0013] When the corresponding solenoid valve is opened, the coolant enters the cooling pipe through the outlet pipe and the inlet pipe, and then flows back through the drain pipe and the guide pipe to achieve subsequent cooling treatment.

[0014] After processing, turn off the infusion pump, circulation pump and solenoid valve, control the electric telescopic rod to retract, separate the inlet pipe from the outlet pipe and the drain pipe from the guide pipe, and open the outer panel to take out the processed leather.

[0015] Preferably, a rotating shaft is rotatably connected to the back of the support base, and the positioning vertical plate is connected to the rotating shaft. The second drive motor is connected to the support base through a first motor mount. The second drive motor is fixed to the support base through the first motor mount, and after starting, it can drive the rotating shaft rotatably connected to the back of the support base to rotate. Because the positioning vertical plate is connected to the rotating shaft, the rotation of the rotating shaft will synchronously drive the positioning vertical plate to adjust its angle.

[0016] Preferably, a connecting protrusion is installed at the center of the inner side of the outer frame plate, and connecting concave plates are added at both ends of the rubbing cylinder, with the connecting protrusion and the connecting concave plates being inserted and connected. When assembling the rubbing cylinder and the outer frame plate, the connecting concave plates at both ends of the rubbing cylinder are aligned with the connecting protrusion at the center of the inner side of the outer frame plate, so that the two are inserted and connected, thus completing the assembly of the rubbing cylinder and the outer frame plate.

[0017] Preferably, the upper surface of the support base has a first groove at the front and rear ends and a second groove at the center, and a bidirectional lead screw is rotatably connected to the center of the inner cavity of the second groove. The first groove at the front and rear ends of the upper surface of the support base provides installation and movement space for related components, and the second groove at the center provides a location for accommodating and installing the bidirectional lead screw. The bidirectional lead screw can rotate at the center of the inner cavity of the second groove, providing a basis for subsequent transmission.

[0018] Preferably, sliding wheels are provided on both sides of the inner cavity of the first groove, and the sliding wheels are connected to the front and rear ends of the lower surface of the outer frame plate. When the outer frame plate needs to move, the sliding wheels connected to the front and rear ends of the lower surface of the outer frame plate roll on both sides of the inner cavity of the first groove, driving the outer frame plate to move along the length direction of the support.

[0019] Preferably, a third drive motor is mounted on the outer side of the support base via a second motor mount, and the third drive motor is coaxially connected to the end of the bidirectional lead screw. Sliding blocks are fitted on both sides of the surface of the bidirectional lead screw, and the sliding blocks are connected to the center of the lower surface of the outer frame plate. The third drive motor is mounted on the outer side of the support base via the second motor mount. After starting, because it is coaxially connected to the end of the bidirectional lead screw, it drives the bidirectional lead screw to rotate. The sliding blocks on both sides of the surface of the bidirectional lead screw move relative to or towards each other as the bidirectional lead screw rotates, thereby driving the outer frame plate connected to the sliding blocks to move synchronously.

[0020] Compared with the prior art, this utility model provides a leather rubbing machine for leather manufacturing, which has the following beneficial effects:

[0021] This leather rubbing machine has cooling pipes connected to the inlet and outlet pipes on the inner wall of the rubbing cylinder. Combined with the inlet pump, circulation pump, and cooling water tank, it forms a cooling medium circulation system that can effectively cool the rubbing cylinder during the rubbing process, preventing the leather from being damaged by the high temperature during the rubbing process and ensuring the quality of the leather rubbing.

[0022] The combined use of the horizontal and vertical positioning plates ensures that the positions of the inlet and outlet pipes, as well as the drain and guide pipes, are accurately aligned after the kneading cylinder has finished rotating, guaranteeing the precision of subsequent pipe connections. Simultaneously, the electric telescopic rod, in conjunction with the fixed base, moves the outlet and guide pipes, further ensuring precise alignment of the inlet and outlet pipes, and the drain and guide pipes, reducing leakage during cooling medium transport and improving operational reliability.

[0030] 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.

[0031] This utility model provides a technical solution: a leather-making and texturing machine, comprising: (see details) Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The support base 1 and the outer frame plates 2 are provided on both sides of the upper surface of the support base 1. A first drive motor 7 is installed on the outer side of the outer frame plate 2. A kneading cylinder 3 is added between the adjacent outer frame plates 2. The first drive motor 7 is coaxially connected to the kneading cylinder 3. An opening and closing outer plate 4 is rotatably connected to the inlet and outlet of the kneading cylinder 3. A cooling pipe is provided on the inner wall of the kneading cylinder 3. An inlet pipe 5 and an outlet pipe 6 are respectively provided on the upper surface and the back of the kneading cylinder 3. The inlet pipe 5 and the outlet pipe 6 are respectively connected to the water inlet end and the water outlet end of the cooling pipe. A positioning horizontal plate 18 is installed at the center of the back of the kneading cylinder 3. A positioning vertical plate 17 is rotatably connected to the back of the support base 1. A second drive motor 16 is coaxially connected to the rotating end of the positioning vertical plate 17. The upper surface of the positioning vertical plate 17 is in contact with the lower surface of the positioning horizontal plate 18.

[0032] The outlet pipe 8 is located directly above the inlet pipe 5, and the outer end of the drain pipe 6 is provided with a guide pipe 9. A fixing seat 10 is installed on the surface of the outlet pipe 8 and the guide pipe 9, and the fixing seat 10 is connected to the outer frame plate 2. An electric telescopic rod 11 is installed on the surface of the fixing seat 10, and the telescopic end of the electric telescopic rod 11 is connected to the corresponding outlet pipe 8 and guide pipe 9 respectively. A solenoid valve is installed on the surface of the inlet pipe 5 and the guide pipe 9.

[0033] The infusion pump 12 and the circulation pump 13 are connected to the corresponding inlet pipe 5 and the guide pipe 9, respectively. Both the infusion pump 12 and the circulation pump 13 are connected to a cooling water tank 14, and the cooling water tank 14 is connected to the outer frame plate 2.

[0034] Open the outer panel 4, put the leather to be processed into the rubbing cylinder 3, then close the outer panel 4, start the second drive motor 16, which drives the positioning vertical plate 17 to rotate around the back of the support base 1, so that the upper surface of the positioning vertical plate 17 separates from the lower surface of the positioning horizontal plate 18.

[0035] The first drive motor 7 is started, which drives the rubbing cylinder 3 to rotate between the outer frame plates 2 to rub the inner leather. The rubbing cylinder 3 is a common and technologically mature device on the market, so it will not be described in detail here.

[0036] After the kneading operation is completed, the first drive motor 7 is turned off, the kneading cylinder 3 stops rotating, the second drive motor 16 is started, and the positioning vertical plate 17 and the positioning horizontal plate 18 are aligned and fitted together, so that the liquid inlet pipe 5 corresponds to the liquid outlet pipe 8 and the liquid drain pipe 6 corresponds to the liquid guide pipe 9.

[0037] The electric telescopic rod 11 on the surface of the control base 10 extends, which pushes the liquid outlet pipe 8 to connect with the liquid inlet pipe 5 and the liquid guide pipe 9 to connect with the liquid drain pipe 6 respectively. After the connection is completed, the electric telescopic rod 11 is closed.

[0038] When the corresponding solenoid valve is opened, the coolant enters the cooling pipe through the outlet pipe 8 and the inlet pipe 5, and then flows back through the drain pipe 6 and the guide pipe 9 to achieve subsequent cooling treatment.

[0039] After processing, turn off the infusion pump 12, circulation pump 13 and solenoid valve, control the electric telescopic rod 11 to retract, so that the outlet pipe 8 is separated from the inlet pipe 5 and the guide pipe 9 is separated from the drain pipe 6, and the outer panel 4 can be opened to take out the processed leather.

[0040] The use of the positioning vertical plate 17 and the positioning horizontal plate 18 in combination allows for precise adjustment of the angle of the kneading cylinder 3 under the drive of the second drive motor 16. This ensures that after the kneading cylinder 3 has rotated, the positions of the inlet pipe 5 and outlet pipe 8, as well as the drain pipe 6 and guide pipe 9, correspond to each other, thus ensuring the accuracy of pipe connection and improving operational convenience.

[0041] Please see Figure 5 A rotating shaft 15 is rotatably connected to the back of the support base 1, and a positioning vertical plate 17 is connected to the rotating shaft 15. A second drive motor 16 is connected to the support base 1 through a first motor mount. The second drive motor 16 is fixed to the support base 1 through the first motor mount. After starting, it can drive the rotating shaft 15 rotatably connected to the back of the support base 1 to rotate. Since the positioning vertical plate 17 is connected to the rotating shaft 15, the rotation of the rotating shaft 15 will synchronously drive the positioning vertical plate 17 to adjust its angle. Through the rotatable connection between the rotating shaft 15 and the support base 1, and in conjunction with the drive of the second drive motor 16, the angle of the positioning vertical plate 17 can be flexibly adjusted. The connection structure is stable, and the drive method is direct and efficient.

[0042] Please see Figure 4An inserting protrusion 20 is installed at the center of the inner side of the outer frame plate 2, and inserting concave plates 19 are added at both ends of the rubbing cylinder 3, with the inserting protrusion 20 and the inserting concave plates 19 inserted and connected. When assembling the rubbing cylinder 3 and the outer frame plate 2, the inserting concave plates 19 at both ends of the rubbing cylinder 3 are aligned with the inserting protrusion 20 at the center of the inner side of the outer frame plate 2, so that the two are inserted and connected, completing the assembly of the rubbing cylinder 3 and the outer frame plate 2. The insertion connection method of the inserting protrusion 20 and the inserting concave plates 19 facilitates the quick assembly and disassembly of the rubbing cylinder 3 and the outer frame plate 2. The connection structure is simple and tightly fitted, ensuring the stability of the cooperation between the two.

[0043] Please see Figure 6 The upper surface of the support base 1 has a first groove 21 at the front and rear ends and a second groove 22 at the center, respectively. A bidirectional lead screw 23 is rotatably connected to the center of the inner cavity of the second groove 22. The first groove 21 at the front and rear ends of the upper surface of the support base 1 provides installation and movement space for related components, while the second groove 22 at the center provides a location for the bidirectional lead screw 23 to be accommodated and installed. The bidirectional lead screw 23 can rotate at the center of the inner cavity of the second groove 22, providing a foundation for subsequent transmission. The arrangement of the first groove 21 and the second groove 22 makes the structural layout of the support base 1 more reasonable and provides suitable installation space for related components. The rotatable connection of the bidirectional lead screw 23 lays the structural foundation for subsequent power transmission and component movement, improving the overall structural coordination. Sliding wheels 24 are added to both sides of the inner cavity of the first groove 21, and the sliding wheels 24 are connected to the front and rear ends of the lower surface of the outer frame plate 2. When the outer frame plate 2 needs to move, the sliding wheels 24 connected to the front and rear ends of the lower surface of the outer frame plate 2 roll on both sides of the inner cavity of the first groove 21, driving the outer frame plate 2 to move along the length direction of the support base 1. The sliding wheels 24 convert the sliding friction between the outer frame plate 2 and the support base 1 into rolling friction, significantly reducing the resistance when the outer frame plate 2 moves, making the movement of the outer frame plate 2 smoother and more stable, and reducing the wear of the components. A third drive motor 25 is mounted on the outer side of the support base 1 through a second motor mount, and the third drive motor 25 is coaxially connected to the end of the bidirectional lead screw 23. Sliding blocks 26 are sleeved on both sides of the surface of the bidirectional lead screw 23, and the sliding blocks 26 are connected to the center of the lower surface of the outer frame plate 2. The third drive motor 25 is mounted on the outside of the support base 1 via the second motor mount. After starting, it is coaxially connected to the end of the bidirectional lead screw 23, driving the bidirectional lead screw 23 to rotate. The sliding blocks 26 on both sides of the surface of the bidirectional lead screw 23 move relative to each other or towards each other as the bidirectional lead screw 23 rotates, thereby driving the outer frame plate 2 connected to the sliding blocks 26 to move synchronously. The third drive motor 25 provides stable power for the movement of the outer frame plate 2. Through the cooperation of the bidirectional lead screw 23 and the sliding blocks 26, the precise and smooth movement of the outer frame plate 2 is achieved. The synchronous movement of the sliding blocks 26 on both sides ensures the consistency of the movement of the outer frame plate 2, improving the accuracy and reliability of the operation.

[0044] In this scheme: the third drive motor 25, which is installed on the outside of the start support 1 through the second motor base, drives the bidirectional lead screw 23, which is coaxially connected to its end, to rotate in the center of the inner cavity of the second groove 22. The sliding blocks 26 sleeved on both sides of the surface of the bidirectional lead screw 23 move relative to each other or towards each other as the bidirectional lead screw 23 rotates, thereby driving the outer frame plate 2 connected to the sliding block 26 to move synchronously. The sliding wheels 24 connected to the front and rear ends of the lower surface of the outer frame plate 2 roll on both sides of the inner cavity of the first groove 21, assisting the outer frame plate 2 to move smoothly along the length of the support 1 until the insertion protrusion 20 at the center of the inner side of the outer frame plate 2 is aligned with the insertion concave plates 19 at both ends of the kneading cylinder 3 and inserted and connected.

[0045] Open the rotating outer plate 4 connected to the inlet and outlet of the rubbing cylinder 3, put the leather to be processed into the rubbing cylinder 3, and then close the outer plate 4.

[0046] Start the second drive motor 16 coaxially connected to the rotating end of the positioning vertical plate 17, which drives the positioning vertical plate 17, which is rotatably connected to the back of the support base 1, to rotate around the back of the support base 1, so that the upper surface of the positioning vertical plate 17 separates from the lower surface of the positioning horizontal plate 18 installed at the center of the back of the kneading cylinder 3.

[0047] Start the first drive motor 7 installed on the outside of the outer frame plate 2, which drives the rubbing cylinder 3 added between the adjacent outer frame plates 2 to rotate between the outer frame plates 2, and perform rubbing operation on the inner leather;

[0048] After the kneading operation is completed, the first drive motor 7 is turned off, the kneading cylinder 3 stops rotating, the second drive motor 16 is started, and the positioning vertical plate 17 is rotated to be aligned and attached with the positioning horizontal plate 18, so that the liquid inlet pipe 5 on the upper surface of the kneading cylinder 3 corresponds to the liquid outlet pipe 8 set directly above it, and the liquid guide pipe 9 added to the outer end of the liquid drain pipe 6 on the back of the kneading cylinder 3 corresponds to it.

[0049] The electric telescopic rod 11 mounted on the surface of the control base 10 extends, and the telescopic end of the electric telescopic rod 11 pushes the corresponding liquid outlet pipe 8 and liquid guide pipe 9 to move, so that the liquid outlet pipe 8 connects with the liquid inlet pipe 5 and the liquid guide pipe 9 connects with the liquid drain pipe 6. After the connection is completed, the electric telescopic rod 11 is closed. The base 10 is mounted on the surface of the liquid outlet pipe 8 and the liquid guide pipe 9 and is connected to the outer frame plate 2.

[0050] Open the solenoid valves installed on the surfaces of the inlet pipe 5 and the guide pipe 9, and start the delivery pump 12 and the circulation pump 13, which are respectively connected to the inlet pipe 5 and the guide pipe 9. The coolant is delivered from the cooling water tank 14, which is connected to both the delivery pump 12 and the circulation pump 13 and is connected to the outer frame plate 2, to the outlet pipe 8 via the delivery pump 12, and then enters the cooling pipe opened on the inner wall of the kneading cylinder 3 via the inlet pipe 5. Subsequently, the coolant flows into the guide pipe 9 via the drain pipe 6, and then flows back to the cooling water tank 14 via the circulation pump 13.

[0051] After processing, turn off the infusion pump 12, circulation pump 13 and solenoid valve, control the electric telescopic rod 11 to retract, so that the outlet pipe 8 is separated from the inlet pipe 5 and the guide pipe 9 is separated from the drain pipe 6, open the outer panel 4 and take out the processed leather.
