Description

Technical Field

[0001] The utility model relates to the technical field of artificial leather, in particular to an artificial leather embossing device. Background Art

[0002] Artificial leather is a synthetic material commonly used to make products similar to genuine leather, such as leather goods, footwear, clothing, furniture, car seat coverings, etc. Artificial leather is originally grainless, and during the processing process, it is pressed to resemble the natural grain of leather as well as designed labels and patterns.

[0003] A Chinese patent (patent number CN215203448U) discloses an artificial leather embossing device, belonging to the field of artificial leather technology. The device includes a workbench with fixed plates fixedly connected to both sides of the workbench's upper surface. One side of the fixed plate defines a groove, and the inner wall of the groove is movably connected to a rotating shaft. One end of the rotating shaft is fixedly connected to a motor, and the other end of the rotating shaft is movably connected to a mounting plate. The motor drives the rotating shaft to rotate a pressing roller, thereby embossing the artificial leather.

[0004] The existing embossing machines for artificial leather production and processing have embossed protrusions on the surface of the embossing roller before use. During actual use, dust is easily retained on the edges of the embossed protrusions on the surface of the embossing roller, resulting in dust marks on the embossed areas on the surface of the synthetic leather during the embossing process, which reduces the embossing forming effect of the synthetic leather. Utility Model Content

[0005] In order to solve at least one of the technical problems mentioned in the background technology, the purpose of the present invention is to provide an artificial leather embossing device to reduce dust on the embossed raised surface and improve production quality.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: an artificial leather embossing device, comprising a workbench, a feeding rod and a receiving rod mounted on the workbench, a first motor for driving the receiving rod to rotate mounted on the workbench, a pad roller mounted on the workbench, a pressure roller mounted on the workbench and located below the pad roller, a second motor for driving the pressure roller to rotate mounted on the workbench, and a cleaning mechanism mounted on the workbench;

[0007] The cleaning mechanism includes a brush roller rotatably mounted on a workbench, the brush roller being located between a pressure roller and a receiving rod, the brush roller being located below the artificial leather, bristles distributed on the surface of the brush roller, the bristles abutting against the surface of the pressure roller, a first gear being fixedly mounted on one side of the pressure roller, a second gear meshing with the first gear being mounted on one side of the brush roller, and the diameter of the first gear being larger than that of the second gear.

[0008] Furthermore, an auxiliary roller is fixedly installed on the workbench, the auxiliary roller is located between the feeding rod and the pressure roller, the auxiliary roller is located below the artificial leather, and bristles in contact with the pressure roller are installed on the surface of the auxiliary roller.

[0009] Furthermore, two guide rollers are installed on the upper side of the workbench, and the two guide rollers are located on both sides of the pad roller. Support frames are installed on both sides of the guide rollers, and the support frames are fixedly connected to the workbench.

[0010] Furthermore, the guide roller is rotatably connected to the support frame, a ball bearing is installed on the support frame, and the guide roller passes through the ball bearing.

[0011] Furthermore, support plates are rotatably installed on both sides of the feeding rod, the support plates are fixedly connected to the workbench, and a pre-tightening mechanism is installed on the support plates.

[0012] Furthermore, the pre-tightening mechanism includes a rotating drum fixedly mounted on the support plate, a friction wheel rotatably mounted inside the rotating drum, the friction wheel contacts the inner wall of the rotating drum, a connecting rod is fixedly mounted at the axis of the friction wheel, and the connecting rod is fixedly connected to the feeding rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are: during the rotation of the pressure roller, the pressure roller drives the first gear to rotate, and the first gear drives the second gear and the brush roller to rotate, so that the bristles on the surface of the brush roller contact the surface of the pressure roller to clean the dust on the surface of the pressure roller. Because the diameter of the first gear is larger than the diameter of the second gear, the rotation speed of the brush roller is greater than the rotation speed of the pressure roller. The brush roller is located on the left side of the pressure roller. When the pressure roller rotates counterclockwise, the brush roller rotates clockwise. Because the rotation speed of the brush roller is greater than the rotation speed of the pressure roller, the bristles on the surface of the brush roller will continuously clean the protrusions on the surface of the pressure roller. Because the artificial leather is located on the upper side of the brush roller and the pressure roller, the brushed dust will fall downward under the action of gravity, reducing the occurrence of dust falling on the surface of the artificial leather.

DETAILED DESCRIPTION

[0020] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1 and Figure 2 The present embodiment provides an artificial leather embossing device, comprising a workbench 1, on which a feeding rod 2 and a receiving rod 3 are installed, a first motor 4 for driving the receiving rod 3 to rotate is installed on the workbench 1, a pad roller 5 is installed on the workbench 1, a pressing roller 6 is installed on the workbench 1 and located below the pad roller 5, a second motor 7 for driving the pressing roller 6 to rotate is installed on the workbench 1, and a cleaning mechanism 8 is installed on the workbench 1.

[0022] At the beginning of the work, the artificial leather on the feeding rod 2 is first passed through the pad roller 5 and the pressure roller 6, and then wound onto the receiving rod 3. The first motor 4 on the receiving rod 3 rotates, driving the receiving rod 3 to rotate, so that the receiving rod 3 continuously rewinds the artificial leather, thereby causing the artificial leather to move between the pad roller 5 and the pressure roller 6. At the same time, the second motor 7 rotates, driving the pressure roller 6 to rotate. The rotation of the pressure roller 6 matches the moving speed of the artificial leather, so that under the interaction between the pressure roller 6 and the pad roller 5, the artificial leather is continuously squeezed to form lines, thereby completing the work of embossing the surface of the artificial leather.

[0023] See also Figure 1 、 Figure 2 and Figure 4 The cleaning mechanism 8 includes a brush roller 81 rotatably mounted on the workbench 1. The brush roller 81 is located between the pressure roller 6 and the receiving rod 3. The brush roller 81 is located below the artificial leather. Brush bristles are distributed on the surface of the brush roller 81, and the bristles abut against the surface of the pressure roller 6. A first gear 82 is fixedly mounted on one side of the pressure roller 6, and a second gear 83 meshing with the first gear 82 is mounted on one side of the brush roller 81. The diameter of the first gear 82 is larger than that of the second gear 83.

[0024] During the rotation of the pressure roller 6, the pressure roller 6 drives the first gear 82 to rotate, and the first gear 82 drives the second gear 83 and the brush roller 81 to rotate, so that the bristles on the surface of the brush roller 81 contact the surface of the pressure roller 6 to clean the dust on the surface of the pressure roller 6. Since the diameter of the first gear 82 is larger than the diameter of the second gear 83, the rotation speed of the brush roller 81 is greater than the rotation speed of the pressure roller 6. Figure 2 As shown, the brush roller 81 is located on the left side of the pressure roller 6. When the pressure roller 6 rotates counterclockwise, the brush roller 81 rotates clockwise. Since the rotation speed of the brush roller 81 is greater than the rotation speed of the pressure roller 6, the bristles on the surface of the brush roller 81 will continuously clean the protrusions on the surface of the pressure roller 6. Since the artificial leather is located on the upper side of the brush roller 81 and the pressure roller 6, the dust brushed off will fall downward under the action of gravity, reducing the occurrence of dust falling on the surface of the artificial leather.

[0025] See also Figure 2 and Figure 3 An auxiliary roller 84 is fixedly installed on the workbench 1. The auxiliary roller 84 is located between the feeding rod 2 and the pressure roller 6. The auxiliary roller 84 is located below the artificial leather. Brush bristles in contact with the pressure roller 6 are installed on the surface of the auxiliary roller 84.

[0026] During the rotation of the pressure roller 6, the protrusion on the pressure roller 6 first contacts the bristles on the brush roller 81, and the brush roller 81 cleans one side of the protrusion. As the pressure roller 6 rotates, the pressure roller 6 drives the cleaned protrusion to move to the auxiliary roller 84, so that the other side of the protrusion that has been cleaned once contacts the bristles on the auxiliary roller 84, and the auxiliary roller 84 cleans the other side of the protrusion, so that both sides of the protrusion on the pressure roller 6 are cleaned by the brush roller 81 and the auxiliary roller 84, thereby improving the cleaning effect.

[0027] See also Figure 2 and Figure 3 Two guide rollers 9 are installed on the upper side of the workbench 1. The two guide rollers 9 are located on both sides of the pad roller 5. Support frames 10 are installed on both sides of the guide rollers 9. The support frames 10 are fixedly connected to the workbench 1.

[0028] The guide roller 9 plays a guiding role for the artificial leather. In the process of the artificial leather moving from the feeding rod 2 to the pad roller 5 and from the pad roller 5 to the receiving rod 3, the guide roller 9 keeps the artificial leather between the pad roller 5 and the pressure roller 6 in a horizontal moving state.

[0029] See also Figure 1 and Figure 4 The guide roller 9 is rotatably connected to the support frame 10. A ball bearing 11 is mounted on the support frame 10, and the guide roller 9 passes through the ball bearing 11. Through the ball bearing 11, when the guide roller 9 is subjected to the friction of the artificial leather, the guide roller 9 will rotate relative to the support frame 10, so that the friction between the guide roller 9 and the artificial leather changes from sliding friction to rolling friction, thereby reducing the wear of the guide roller 9 on the surface of the artificial leather.

[0030] The feed rod 2 rotates, causing the artificial leather to continuously detach from the feed rod 2. However, during the rotation of the feed rod 2, if the feed rod 2 is subjected to a small torque other than that on the artificial leather, that is, if there is no corresponding pre-tightening force on the feed rod 2 during the rotation of the artificial leather, the feed rod may easily rotate too fast, and the movement speed of the artificial leather cannot keep up with the rotation of the feed rod, resulting in excessive detachment of the artificial leather. Support plates 12 are rotatably mounted on both sides of the feed rod 2, and the support plates 12 are fixedly connected to the workbench 1. A pre-tightening mechanism 13 is mounted on the support plates 12.

[0031] As the artificial leather continuously detaches from the feed rod 2 and causes the feed rod 2 to continuously rotate, if the speed of the artificial leather detaching decreases, the pre-tightening mechanism 13 will limit the feed rod 2 and reduce the rotation speed of the feed rod 2 accordingly, thereby reducing the mismatch between the rotation speed of the feed rod 2 and the speed of the artificial leather detaching, resulting in the artificial leather stacking on the workbench 1.

[0032] See also Figure 4 and Figure 5 The pre-tightening mechanism 13 includes a rotating drum 131 fixedly mounted on the support plate 12, a friction wheel 132 is rotatably mounted inside the rotating drum 131, the friction wheel 132 contacts the inner wall of the rotating drum 131, a connecting rod 133 is fixedly mounted at the axis of the friction wheel 132, and the connecting rod 133 is fixedly connected to the feeding rod 2.

[0033] The movement of the artificial leather drives the feed rod 2 to rotate, and the feed rod 2 drives the friction wheel 132 to rotate through the connecting rod 133. The friction wheel 132 rotates in the rotating drum 131 and contacts and rubs against the inner wall of the rotating drum 131. When the speed at which the artificial leather separates from the feed rod 2 decreases, the rotational torque applied to the feed rod 2 also changes. Therefore, after the rotational torque overcomes the friction between the friction wheel 132 and the inner wall of the rotating drum 131, the remaining force driving the feed rod to rotate is reduced, so that the rotational speed of the feed rod 2 can be reduced in a short time.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
