Description

Technical Field

[0001] This utility model relates to the field of synthetic leather processing technology, and more specifically, it relates to a pressing machine for synthetic leather production. Background Technology

[0002] Synthetic leather is a plastic product that mimics the composition and structure of natural leather and can serve as a substitute. It is typically made with an impregnated non-woven fabric as the mesh layer and a microporous polyurethane layer as the grain layer. Both its front and back are very similar to leather, and it possesses a certain degree of breathability, making it closer to natural leather than ordinary artificial leather. It is widely used in the production of shoes, boots, bags, and sports equipment.

[0003] When manufacturing leather bags, the leather needs to be pressed at the edges to achieve an aesthetic purpose. Existing pressing machines are fixed on a frame, requiring manual movement of the leather or fabric to press the edges at different locations. However, this pressing method can cause wrinkles to form on the leather or fabric during processing due to manual movement. Wrinkles can affect the appearance of the produced leather, and consequently, the quality of the leather product. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pressing machine for synthetic leather production, which can press and fix the synthetic leather during the pressing process through a pressing mechanism, thereby preventing the synthetic leather from shifting and wrinkling during the pressing process.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a pressing machine for synthetic leather production, comprising a frame and a pressing mechanism disposed on the frame, wherein a transmission mechanism and a pressing mechanism are disposed on the frame, the transmission mechanism comprising unwinding rollers and rewinding rollers disposed at both ends of the frame and a first motor for driving the unwinding rollers and rewinding rollers, the pressing mechanism and the pressing mechanism being disposed in the same straight line, the pressing mechanism comprising a pressing plate and a driving member disposed on the pressing plate, the driving member being used to drive the pressing plate close to the surface of the frame.

[0006] By adopting the above technical solution, synthetic leather is wound onto the unwinding roller, and then pulled from the unwinding roller to the take-up roller by the drive of the first motor to achieve winding. Between the unwinding and take-up roller positions, the synthetic leather undergoes edge pressing by a pressing mechanism. This pressing mechanism is a relatively mature existing technology. It uses a driving component to press the edge of the synthetic leather. During pressing, the operator uses a driving component to gradually move the pressing plate closer to the surface of the frame, which is also closer to the surface of the synthetic leather being transported along the frame. The surface of the synthetic leather is gradually approached by the pressing plate until it is close to the surface of the frame. The synthetic leather is pressed close to the surface of the frame. After the edge pressing of the synthetic leather is completed, the pressing plate is moved away from the synthetic leather by the driving component. Then the synthetic leather is transported and wound up. After the synthetic leather is wound up once, the synthetic leather transported to the pressing mechanism is pressed and edge-pressed. This eliminates the need for the operator to transport the synthetic leather manually, thus preventing the synthetic leather from shifting during the transport and edge pressing process. This improves the efficiency and quality of synthetic leather production.

[0007] The present invention is further configured such that: the driving component includes a cylinder for driving the pressing plate close to the surface of the frame, and the cylinder is fixedly connected between the pressing plate and the frame.

[0008] By adopting the above technical solution, the operator drives the extension of the cylinder to move the pressing plate closer to the synthetic leather to be processed, so that the pressing plate is in contact with the surface of the frame to achieve the effect of pressing the synthetic leather onto the surface of the frame. Moreover, the cylinder structure is simple and convenient for operators and enterprises to purchase or operate.

[0009] The present invention is further configured such that a first telescopic rod is provided between the pressing plate and the frame.

[0010] By adopting the above technical solution, the first telescopic rod will extend and retract between the pressing plate and the frame as the cylinder extends and retracts. This increases the stability of the cylinder during a single drive under the constraint of the first telescopic rod, ensuring the linear movement of the pressing plate driven by the cylinder, and ensuring the stability when the cylinder drives the pressing plate close to the synthetic leather. At the same time, the first telescopic rod is driven in the same way as the cylinder, except that it is not driven by external air or hydraulic means, but is just a telescopic rod setting, which is also a relatively mature structure in the existing technology.

[0011] The present invention is further configured such that: the driving component includes a second motor mounted on the frame, a threaded rod fixedly connected to the output shaft of the second motor, a nut seat sleeved on the threaded rod, and a connecting rod disposed between the nut seat and the pressing plate, wherein the nut seat has a threaded groove inside for the threaded rod to rotate.

[0012] By adopting the above technical solution, the operator turns on the second motor to drive the threaded rod to rotate on the frame. The threaded rod rotates within the threaded groove of the nut seat. As the threaded rod rotates continuously, the nut seat, through the connecting rod, drives the pressing plate to move closer to the synthetic leather until it is close to the synthetic leather, preventing the synthetic leather from moving or shifting. Then, the second motor is turned off, achieving the effect of pressing and fixing the synthetic leather. When the pressing plate needs to move away from the synthetic leather and the synthetic leather is processed, the installation package is moved back to the initial position. The operator needs to use the reversing switch to drive the output shaft of the second motor to rotate in the opposite direction. This controls the threaded rod to rotate counterclockwise and drives the nut seat and the pressing plate to move away from the plane where the synthetic leather is placed. The pressing plate moves back to the initial position, which is convenient for the operator to control and drive.

[0013] The present invention is further configured such that a second telescopic rod is provided between the nut seat and the frame.

[0014] By adopting the above technical solution, the second telescopic rod can achieve the effect of telescoping between the frame and the nut seat as the nut seat moves, thus preventing the nut seat from rotating with the threaded rod, thereby ensuring the stability of the nut seat driving the pressing plate closer to the synthetic leather.

[0015] The present invention is further provided that: an anti-slip sleeve is fitted on the pressing plate.

[0016] By adopting the above technical solution, the anti-slip sleeve can increase the friction between the pressing plate and the synthetic leather. Compared with anti-slip structures such as anti-slip protrusions, the anti-slip sleeve will not cause wear to the synthetic leather. It is also convenient to remove the anti-slip sleeve from the pressing plate for replacement or to not use the anti-slip sleeve.

[0017] The present invention is further configured such that the pressing plate is provided with arc surfaces on all four sides.

[0018] By adopting the above technical solution, the arc surface design prevents the synthetic leather from being damaged due to the sharp part of the pressing plate touching the synthetic leather when the pressing plate approaches it, thus protecting the synthetic leather and ensuring the quality of the synthetic leather produced.

[0019] In summary, this utility model has the following beneficial effects: under the action of the transmission mechanism and the pressing mechanism, the synthetic leather can be pressed, transmitted and fixed during the pressing process, thereby preventing the synthetic leather from shifting and wrinkling during the pressing process, ensuring the stability of the synthetic leather transmission and the stability during pressing, and thus improving the quality of the synthetic leather produced.

[0026] The present invention will now be described in detail with reference to the accompanying drawings.

[0027] A pressing machine for synthetic leather production, referring to Figures 1-2The system includes a frame 1 and a pressing mechanism mounted on the frame 1. The frame 1 is equipped with a transmission mechanism and a pressing mechanism. The pressing mechanism and the pressing mechanism are not arranged in a straight line. The operation of the pressing mechanism and the operation of the pressing mechanism do not affect each other. The transmission mechanism includes an unwinding roller 3 and a winding roller 4 arranged at both ends of the frame 1, and a first motor 2 for driving the unwinding roller 3 and the winding roller 4. The pressing mechanism and the pressing mechanism are arranged in a straight line. The pressing mechanism includes a pressing plate 9 and a driving member arranged on the pressing plate 9. The driving member is used to drive the pressing plate 9 close to the surface of the frame 1.

[0028] The pressing plate 9 is fitted with an anti-slip sleeve, and the pressing plate 9 has rounded surfaces around its perimeter. The anti-slip sleeve increases the friction between the pressing plate 9 and the synthetic leather. Compared with anti-slip protrusions or other anti-slip structures, the anti-slip sleeve will not cause wear to the synthetic leather. It is also convenient to remove and replace the anti-slip sleeve from the pressing plate 9 or to not use the anti-slip sleeve at all. At the same time, the rounded surfaces prevent the surface of the synthetic leather from being damaged when the pressing plate 9 is close to the synthetic leather due to the sharp part of the pressing plate 9 touching the synthetic leather. This protects the synthetic leather and ensures the quality of the synthetic leather produced.

[0029] Example 1: The driving component includes a cylinder 7 for driving the pressing plate 9 close to the surface of the frame 1. The cylinder 7 is fixedly connected between the pressing plate 9 and the frame 1. A first telescopic rod 8 is provided between the pressing plate 9 and the frame 1.

[0030] Working principle: Synthetic leather is wound onto the unwinding roller 3, and then driven by the first motor 2, the synthetic leather is partially pulled from the unwinding roller 3 onto the take-up roller 4 for winding. Between the positions of the synthetic leather on the unwinding roller 3 and the take-up roller 4, an edge-pressing mechanism performs an edge-pressing operation. This edge-pressing mechanism is a relatively mature existing technology. It uses a driving component to press the edge of the synthetic leather. During edge-pressing, the operator needs to use a driving component to gradually move the pressing plate 9 closer to the surface of the frame 1, which is also closer to the synthetic leather being transported along the surface of the frame 1. The surface of the synthetic leather is gradually approached by the pressing plate 9 until it is close to the surface of the frame 1, so that the synthetic leather is pressed close to the surface of the frame 1. After the synthetic leather is pressed, the pressing plate 9 is driven away from the synthetic leather by the driving component. Then the synthetic leather is transported and wound up. After the synthetic leather is wound up once, the synthetic leather transported to the pressing mechanism is pressed and pressed. This eliminates the need for the operator to transport the synthetic leather manually, thus preventing the synthetic leather from shifting during the transport and pressing process, thereby improving the efficiency and quality of synthetic leather production.

[0031] The operator extends the cylinder 7 to bring the pressing plate 9 closer to the synthetic leather to be processed, so that the pressing plate 9 fits against the surface of the frame 1 to press the synthetic leather onto the surface of the frame 1. The cylinder 7 has a simple structure and is convenient for operators and companies to purchase or operate.

[0032] The first telescopic rod 8 extends and retracts between the pressing plate 9 and the frame 1 as the cylinder 7 extends and retracts. This increases the stability of the cylinder 7 during a single drive under the constraint of the first telescopic rod 8, ensuring the linear movement of the pressing plate 9 driven by the cylinder 7, and ensuring the stability of the pressing plate 9 when the cylinder 7 drives it close to the synthetic leather. At the same time, the first telescopic rod 8 is driven in the same way as the cylinder 7, except that it is not driven by external air or hydraulic means, but is simply a telescopic rod setting, which is also a relatively mature structure in the existing technology.

[0033] Example 2: Compared with Example 1, Example 2 differs in that: the driving component includes a second motor 10 mounted on the frame 1, a threaded rod 11 fixedly connected to the output shaft of the second motor 10, a nut seat 12 sleeved on the threaded rod 11, and a connecting rod disposed between the nut seat 12 and the pressing plate 9. The nut seat 12 has a threaded groove inside for the threaded rod 11 to rotate, and a second telescopic rod 13 is disposed between the nut seat 12 and the frame 1.

[0034] Working principle: The operator turns on the second motor 10 to drive the threaded rod 11 to rotate on the frame 1. The threaded rod 11 rotates in the threaded groove of the nut seat 12. As the threaded rod 11 rotates continuously, the nut seat 12 drives the pressing plate 9 to move closer to the synthetic leather through the connecting rod until it is close to the synthetic leather, preventing the synthetic leather from moving or shifting. Then the second motor 10 is turned off, achieving the effect of pressing and fixing the synthetic leather. When the pressing plate 9 needs to move away from the synthetic leather and the synthetic leather is processed, the installation package is moved back to the initial position. The operator needs to use the reversing switch to drive the output shaft of the second motor 10 to rotate in the opposite direction. This controls the threaded rod 11 to rotate counterclockwise and drives the nut seat 12 and the pressing plate 9 to move away from the plane where the synthetic leather is placed. The pressing plate 9 moves back to the initial position, which is convenient for the operator to control and drive.

[0035] The second telescopic rod 13 is designed to extend and retract between the frame 1 and the nut seat 12 as the nut seat 12 moves, thus preventing the nut seat 12 from rotating with the threaded rod 11 and ensuring the stability of the nut seat 12 in driving the pressing plate 9 closer to the synthetic leather.

[0036] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
