Description

Technical Field

[0001] The present application relates to the technical field of synthetic leather, and in particular to a polarization device for semi-silicon synthetic leather. Background Art

[0002] In the production process of semi-silicone synthetic leather, a layer of PU coating needs to be coated on the surface of the coated silicone layer to support the silicone layer. In the subsequent stitching process, the pinholes on the silicone layer will be restricted by the PU coating and will not be enlarged, making the entire semi-silicone synthetic leather stronger.

[0003] However, since silicone is a non-polar material, the connection strength between silicone and PU coating is low during the bonding process, which can easily lead to separation between silicone and PU coating, thereby reducing the quality of semi-silicone synthetic leather.

[0004] Therefore, it is necessary to propose a new technical solution to solve the above problems. Utility Model Content

[0005] In order to make the connection between the silicone and the PU coating more firmly, thereby making the strength of the semi-silicon synthetic leather higher, the present application provides a polarization device for the semi-silicon synthetic leather.

[0010] By adopting the above technical solution, the movement of the synthetic leather is detected by using the detection component, so that after the synthetic leather stops moving, the polarizing element can also stop working, so that the silicone on the surface of the synthetic leather will not be over-polarized.

[0011] Optionally: the frame is also provided with an extraction component for extracting ozone generated by polarization, the extraction component includes an extraction hood with a lower opening arranged on the frame and an extraction tube connected to the extraction hood, the extraction tube is connected to the inner cavity of the extraction hood, and the polarization component is arranged in the extraction hood.

[0012] By adopting the above technical solution, when the polarizing element polarizes the control machine silica gel to generate ozone, the ozone is extracted by the extraction component, so that the sample will not diffuse into the production environment, making the workers less susceptible to harm from the ozone.

[0013] Optionally: a vertical driving member for driving the extraction hood to move vertically is also provided on the frame, and a free end of the vertical driving member is connected to the end of the extraction hood.

[0014] By adopting the above technical solution, after foreign matter adheres to the surface of the synthetic leather, the polarizing element can move upwards to increase the distance between the synthetic leather and the polarizing element, so that the transportation of the synthetic leather is not easily affected.

[0015] Optionally: a horizontal driving member for driving the polarizing member to move horizontally is also provided on the extraction cover, and the horizontal driving member is connected to the polarizing member.

[0016] By adopting the above technical solution, after the position of the synthetic leather changes, the position of the polarizing element can be adjusted accordingly, so that the polarizing element can still polarize the silica gel on the surface of the synthetic leather.

[0017] Optional: The horizontal driving member includes two lead screws rotatably connected to the extraction cover, a rotating member driving the lead screws to rotate, a slider slidably arranged on the extraction cover, and a movable plate connected to the slider, the upper end of the extraction cover is penetrated by a sliding groove, the movable plate is arranged at the upper end of the sliding groove and covers the upper end opening of the sliding groove, the lower end of the movable plate is connected to the polarization member, the lead screws are respectively arranged on both sides of the sliding groove, the lead screws are passed through the slider and are threadedly connected to the slider.

[0018] By adopting the above technical solution, the rotating member drives the lead screw to rotate, and the lead screw drives the movable plate to move horizontally, so that the polarizing member connected to the bottom of the movable plate can move horizontally, so that the polarizing member can stably polarize the silicone on the synthetic leather.

[0019] Optionally: two position sensors for detecting the position of the synthetic leather are arranged on the extraction cover, and the detection ends of the position sensors are respectively facing the upper end surfaces of the synthetic leather.

[0020] By adopting the above technical solution, the position of the polarizing element is limited by the position sensor, so that after the position of the synthetic leather is changed, the position of the synthetic leather can be detected by the position sensor and the rotating element can be operated to realize automatic adjustment of the polarizing element.

[0021] Optionally: a gap is left between the two position sensors in the width direction of the synthetic leather, and the two position sensors are located on the same side of the synthetic leather.

[0022] By adopting the above technical solution, a position sensor is used to detect the position of the textile cloth, and another position sensor is used to detect the position of the silicone layer. When both sensors detect a position, the polarizing element does not move.

DETAILED DESCRIPTION

[0031] The present application is further described in detail below in conjunction with the accompanying drawings.

[0032] The present application discloses a polarization device for semi-silicon synthetic leather, such as Figure 1 and Figure 2As shown, it includes a frame 1, a polarizing element 11 arranged on the frame 1, a guide roller 12 for guiding the synthetic leather to move to the bottom of the polarizing element 11, and two guide rollers 13 for driving the synthetic leather to adhere to the top of the guide roller 12. The guide roller 12 and the guide roller 13 are both rotatably connected to the frame 1. The guide roller 12 is arranged close to the polarizing element 11. The two guide rollers 13 are respectively located on both sides of the guide roller 12 and are arranged below the lower end surface of the guide roller 12. The synthetic leather bypasses from below the two guide rollers 13 and bypasses from above the guide roller 12, so that the upper end surface of the synthetic leather is close to the polarizing element 11. The polarizing element 11 is a discharge device, which polarizes the air and the silicone layer by discharge, so that the silicone layer is oxidized, thereby enhancing the connection strength between the silicone layer and the PU coating.

[0033] Since the silicone layer needs a certain amount of time to be oxidized, the polarizing element 11 stops working when necessary after the silicone layer stops moving. Therefore, a detection assembly 2 for detecting the rotation of the guide roller 12 is also provided on the frame 1. The detection assembly 2 includes a detection disk 21 coaxially fixed to one end of the guide roller 12 and a detection sensor 22 for detecting the rotation of the detection disk 21. The detection disk 21 is fixed to the end of the guide roller 12 by bolts, and a plurality of detection grooves 211 are circumferentially provided at one end of the detection disk 21 away from the guide roller 12. In this embodiment, the detection sensor 22 is a distance sensor. The detection sensor 22 is fixed to the frame 1 by bolts. The detection end of the detection sensor 22 faces the detection groove 211, and the detection sensor 22 is electrically connected to the control unit that controls the start and stop of the polarizing element 11. When the detection sensor 22 does not detect the movement of the groove, the control unit can control the polarizing element 11 to stop working.

[0034] like Figure 1 As shown, since the polarizer 11 will ionize the air and generate ozone when it is working, the increased concentration of ozone will cause harm to the human body. Therefore, the frame 1 is also provided with an extraction component 3 for extracting ozone, and the extraction component 3 includes an extraction hood 31 with a lower opening arranged on the frame 1 and an extraction pipe 32 connected to the extraction hood 31, one end of the extraction pipe 32 is connected to the outer wall of the extraction hood 31 and communicates with the inner cavity of the extraction hood 31, and the other end of the extraction pipe 32 is connected to the exhaust system, so as to extract the ozone generated by ionization in the extraction hood 31. The polarizer 11 is arranged in the extraction hood 31, so that most of the ozone generated by the polarizer 11 ionizing the air can be located in the extraction hood 31 and extracted.

[0035] When the polarizer 11 is processing synthetic leather, the distance between the polarizer 11 and the synthetic leather is 3-5 mm, so when there are foreign objects attached to the synthetic leather, it will affect the synthetic leather from passing between the polarizer 11 and the guide roller 12. Therefore, the frame 1 is also provided with a vertical driving member 14 for driving the extraction cover 31 and the polarizer 11 to move vertically. In this embodiment, the vertical driving member 14 uses an electric cylinder. The vertical driving member 14 is fixed to the frame 1 with bolts, and the free end of the vertical driving member 14 is connected to the end of the extraction cover 31, thereby driving the extraction cover 31 and the polarizer 11 to move vertically at the same time, so that the synthetic leather with foreign objects attached can pass smoothly through the extraction cover 31 and the polarizer 11.

[0036] like Figure 2 As shown, when the synthetic leather passes over the guide roller 12, the synthetic leather will also move along the axis direction of the guide roller 12, so that the polarizing element 11 cannot polarize the entire surface of the synthetic leather. Therefore, the extraction cover 31 is also provided with a horizontal driving element 4 that drives the polarizing element 11 to reciprocate along the axis of the guide roller 12. The horizontal driving element 4 includes two lead screws 41 rotatably connected to the extraction cover 31, a rotating element 42 that drives the lead screws 41 to rotate synchronously, a slider 43 slidably arranged on the extraction cover 31, and a moving plate 44 connected to the slider 43. The upper end of the extraction cover 31 is penetrated by a sliding groove 311 that is connected to its inner cavity. The moving plate 44 is arranged above the extraction cover 31 and closes the sliding groove 311. The lower end of the moving plate 44 is also fixed with a connecting rod 45 by bolts, and the end of the connecting rod 45 away from the moving plate 44 is fixed to the polarizing element 11 by bolts. Two lead screws 41 are respectively arranged on both sides of the sliding groove 311, and respectively pass through the slider 43 and are threadedly matched with the slider 43. The upper end of the moving plate 44 is also fixed with a connecting plate by bolts, and the two ends of the connecting plate are respectively fixed with the slider 43 by bolts, so as to drive the moving plate 44 to move during the movement of the slider 43. In this embodiment, the rotating member 42 uses a servo motor, which is connected to the two lead screws 41 at the same time through a reducer, so as to drive the two lead screws 41 to rotate synchronously.

[0037] like Figure 4As shown, the extraction cover 31 is also provided with position sensors 34 for detecting the positions of the two side walls of the synthetic leather respectively. In this embodiment, the position sensor 34 is a laser sensor. A detection rod 33 is fixed to a slider 43 by bolts. The end of the detection rod 33 away from the slider 43 is tilted downward. Both position sensors 34 are fixed to the end of the detection rod 33 away from the slider 43 by bolts. A gap is left between the two position sensors 34, and a gap is also left between the two position sensors 34 in the width direction of the synthetic leather. The detection end of one position sensor 34 faces the silicone, and the monitoring end of the other position sensor 34 faces the textile cloth, and the two position sensors 34 and the rotating member 42 are all electrically connected to the control unit, so that the position of the synthetic leather is detected by the two position sensors 34. When a position sensor 34 close to the middle of the polarizing member detects the silicone and the other position sensor 34 detects the textile cloth, the rotating member 42 is stopped. When one position sensor 34 does not detect the textile cloth, the polarizing member 11 is moved away from the position sensor 34 until the position sensor 34 detects the textile cloth. When the position sensor 34 close to the polarizing member 11 does not detect the silicone, the polarizing member 11 moves away from the position sensor 34, so that the polarizing member 11 can always stably polarize the silicone.

[0038] The implementation principle of this embodiment is as follows: the synthetic leather passes under the guide roller 13, then passes over the guide roller 12, and then passes under the guide roller 13. The polarizing element 11 ionizes the silica gel on the surface of the synthetic leather, thereby polarizing the silica gel. When the position of the synthetic leather changes, the position of the synthetic leather is detected by the position sensor 34, and the start and stop of the rotating element 42 is controlled by the control unit, so that the polarizing element 11 moves to the top of the synthetic leather.

[0039] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
