Description

Technical Field

[0001] The invention relates to the technical field of cloth squeezing and rolling, in particular to a mechanism for squeezing imitation leather fabric after film coating, water cooling and shaping. Background Art

[0002] In the production process of imitation leather fabrics, the squeezing step after cooling and film formation is a critical step in ensuring final product quality. Existing squeezing methods typically use rollers or extrusion devices to remove excess liquid and solvent from the material. However, these traditional methods often struggle to ensure processing efficiency while avoiding damage to the imitation leather surface, resulting in reduced product quality.

[0003] While existing fabric squeezing devices can squeeze moisture from fabric through the squeeze gap between two sets of squeezing rollers, improving squeezing efficiency, the gap between the two sets of squeezing rollers cannot be adjusted to accommodate different fabric types and thicknesses. This not only limits the versatility of the device but can also damage the fabric due to inappropriate squeezing force, reducing fabric processing quality.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Summary of the Invention

[0005] In response to the problems in the related art, the present invention proposes a mechanism for squeezing out imitation leather fabric after film coating and water cooling and shaping, so as to overcome the above technical problems existing in the existing related art.

[0006] To this end, the specific technical solutions adopted in the present invention are as follows:

[0007] A mechanism for squeezing imitation leather fabric after lamination, water cooling, and shaping includes a frame; a driving roller is rotatably provided on the upper portion of the frame, one end of the driving roller being connected to the output shaft of a reduction motor disposed on the frame; a slider is provided at each end of the frame for sliding up and down, and a lifting assembly is provided on the frame for driving the slider to move up and down; the two ends of the passive roller are connected to two bearings disposed on the sliders; the squeezing gap between the active roller and the passive roller is adjusted by raising and lowering the lifting assembly to meet the squeezing requirements of different imitation leather fabrics;

[0008] The frame is provided with a tensioning guide roller on the feed side. The tensioning guide roller is in an upward curved arc shape for tensioning the imitation leather fabric, and the outer wall of the tensioning guide roller is provided with an elastic sleeve; the outer peripheral sleeve of the active roller is provided with a pressing sleeve made of rubber or plastic material; the outer peripheral sleeve of the passive roller is provided with a pressing sleeve made of rubber or plastic material.

[0009] As a preferred solution, a limiting guide rod is provided on the frame above the tensioning guide roller.

[0010] As a preferred solution, a water tank is provided on the frame below the passive roller.

[0011] As a preferred solution, the lifting assembly includes a pair of vertically upwardly arranged stroke-adjustable cylinders, and the output ends of the cylinders are connected to the slider.

[0012] As a preferred solution, it also includes a cleaning assembly, which includes a V-shaped guide plate arranged on the feeding side of the active roller at the top of the frame, and the V-shaped guide plate is inclined downward from the middle to the end; mounting plates are respectively provided at both ends of the V-shaped guide plate; the two sets of mounting plates are connected by a connecting rod, and an arc-shaped scraper is movably sleeved on the connecting rod;

[0013] Spring ears are symmetrically provided at both ends of the arc scraper; a torsion spring that matches the spring ear is sleeved on the connecting rod to press the arc scraper onto the surface of the active roller, and the other end of the torsion spring is connected to the mounting plate. Several drainage ports are provided at the bottom of both ends of the V-shaped guide plate.

[0014] As a preferred solution, the arc surface of the arc scraper and the arc surface of the active roller are in a concentric circle structure.

[0015] As a preferred solution, a supporting roller is provided on the frame at the discharging side.

[0016] As a preferred solution, a limiting guide rod is provided on the frame above the supporting roller on the discharge side.

[0017] The beneficial effects of the present invention are:

[0018] The present invention utilizes a lifting component to accurately adjust the squeezing gap according to the needs of the imitation leather fabric, optimizes the squeezing and subsequent drying efficiency, reduces energy consumption, shortens the processing cycle, and enhances the flexibility of the equipment.

[0019] Since the frame is provided with a tensioning guide roller on the feeding side, the tensioning guide roller is in an upward curved arc shape to tension the imitation leather fabric, which can support the fabric that sinks in the middle during the conveying process, and avoid the fabric wrinkling when the active roller and the passive roller squeeze the fabric. The outer wall of the tensioning guide roller is provided with an elastic sleeve, which can better tension the fabric.

[0020] The present invention utilizes a cleaning assembly that closely cooperates with the active roller to effectively scrape away residual moisture from the active roller. This moisture then falls onto the V-shaped guide plate below and flows out from both ends along the slope of the V-shaped guide plate. This prevents moisture from dripping back onto the already squeezed imitation leather fabric on the discharge side of the active roller. BRIEF DESCRIPTION OF THE DRAWINGS

They are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. By referring to these contents, ordinary technicians in this field should be able to understand other possible implementation methods and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0030] According to an embodiment of the present invention, a mechanism for squeezing out imitation leather fabric after film coating, water cooling and shaping is provided.

[0031] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. Figure 1-Figure 5 As shown, the imitation leather fabric film-coated water-cooled shaping and then squeezed dry mechanism according to the embodiment of the present invention includes a frame 1; an operating table 2 is arranged on one side of the frame 1;

[0032] A driving roller 302 is rotatably mounted on the upper portion of the frame 1. One end of the driving roller 302 is connected to the output shaft of a reduction motor 303 mounted on the frame 1. A slider 403 is mounted at each end of the frame 1, sliding vertically. A lifting assembly 4 is provided on the frame 1 to drive the sliders 403 up and down. The lifting assembly 4 includes a pair of vertically upward-mounted, adjustable-stroke cylinders 401, the output ends of which are connected to the sliders 403. The ends of the passive roller 404 are connected to two bearings 402 mounted on the sliders 403. The lifting assembly 4 is raised and lowered to adjust the squeeze gap between the driving roller 302 and the passive roller 404 to accommodate the squeeze requirements of different imitation leather fabrics. A water tank 9 is mounted on the frame 1 below the passive roller 404.

[0033] The frame 1 is provided with a tensioning guide roller 7 on the feed side. The tensioning guide roller 7 is in an upwardly curved arc shape for tensioning the imitation leather fabric, and the outer wall of the tensioning guide roller 7 is covered with an elastic sleeve. The outer periphery of the active roller 302 is covered with a rubber or plastic material pressure sleeve; the outer periphery of the passive roller 404 is covered with a rubber or plastic material pressure sleeve. The frame 1 is provided with a limit guide rod 6 above the tensioning guide roller 7.

[0034] It also includes a cleaning component 5, which includes a V-shaped guide plate 501 arranged on the feeding side of the active roller 302 at the top of the frame 1, and a pair of mounting rods 502 matching the slots 3 on the frame 1 are provided at both ends of the V-shaped guide plate 501, and the V-shaped guide plate 501 is inclined downward from the middle to the end; mounting plates 503 are provided at both ends of the V-shaped guide plate 501; the two groups of mounting plates 503 are connected by a connecting rod 504, and an arc-shaped scraper 505 is movably provided on the connecting rod 504; the arc surface of the arc scraper 505 is concentric with the arc surface of the active roller 302.

[0035] Spring ears 507 are symmetrically provided at both ends of the arc scraper 505; a torsion spring 506 that cooperates with the spring ear 507 is mounted on the connecting rod 504 to press the arc scraper 505 onto the surface of the active roller 302, and the other end of the torsion spring 506 is connected to the mounting plate 503. A number of drainage ports 508 are provided at the bottom of both ends of the V-shaped guide plate 501.

[0036] The frame 1 is provided with a supporting roller 8 on the discharging side. A limiting guide rod 6 is provided above the supporting roller 8 on the discharging side on the frame 1.

[0037] The specific operating principle of the cleaning assembly 5 is as follows: When the driving roller 302 rotates, water droplets may remain at the outlet of the squeezed imitation leather fabric. The curved scraper 505, in close contact with the driving roller 302, scrapes away the remaining water droplets, causing them to fall onto the V-shaped deflector 501 for diversion. Ultimately, these water droplets are collected in the water tank 9.

[0038] The arc surface of the arc scraper 505 and the arc surface of the active roller 302 are concentric circles, thereby ensuring that the arc scraper 505 cleans the surface of the active roller 302 more efficiently and thoroughly during operation.

[0039] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation mode of the present invention in actual process is described in detail below.

[0040] like Figure 1-Figure 5 As shown, in actual use, the operating console 2 is electrically connected to the reduction motor 303 and the oil cylinder 401 in sequence. First, the operator activates the two sets of oil cylinders 401 (the specific working principle of the lifting assembly 4 is described above) through the human-machine interface (HMI) on the operating console 2, causing the passive roller 404 to move away from the active roller 302. The operator then inserts the cleaned imitation leather fabric between the limiting guide rod 6 and the tensioning guide roller 7 on the feed side, then passes through the gap between the passive roller 404 and the active roller 302, and finally exits between the limiting guide rod 6 and the supporting roller 8 on the other side. Next, the operator again activates the two sets of oil cylinders 401 through the human-machine interface (HMI) on the operating console 2, raising them and adjusting the distance to the optimal value based on the specific requirements of the imitation leather fabric. Subsequently, the operator again activates the reduction motor 303 (the specific working principle of the rotating assembly 3 is described above) through the operating console 2, driving the active roller 302 to rotate counterclockwise, squeezing and conveying the imitation leather fabric.
