Description

Technical Field

[0001] This invention relates to the field of leather smart card processing equipment, and in particular to an automatic edge-oiling machine and a production line including the automatic edge-oiling machine. Background Technology

[0002] With the continuous advancement of smart card technology, various magnetic stripe cards and IC cards have been widely used in finance, social security, public transportation, intelligent building security systems, and business memberships. Among the existing smart cards, some are made of leather; however, the edges of leather smart cards typically require edge painting.

[0003] Existing automatic edge-painting machines include a spindle box, a grinding wheel, an edge oil groove, and an edge-painting toothed bar. The grinding wheel, edge oil groove, and edge-painting toothed bar are all connected to the spindle box, and they rotate relative to the spindle box around their own axes. The axes of the grinding wheel and the edge-painting toothed bar are perpendicular to each other. Both the grinding wheel and the edge-painting toothed bar are partially inserted vertically into the edge oil groove. The center of the grinding wheel's peripheral wall is concave to form an oil delivery groove, through which the edge oil in the edge oil groove is transferred to the edge-painting toothed bar. Using this machine for edge-painting leather smart cards typically requires the user to manually rotate the leather smart card near the brush roller of the edge-painting machine to apply the edge oil. Prolonged edge-painting operations can easily cause user fatigue, and if the operation is not performed correctly, the risk of injury is relatively high. Summary of the Invention

[0004] In order to solve the problems existing in the prior art, the first objective of the present invention is to provide an automatic edge-oiling machine that can automatically perform edge-oiling process on square products.

[0005] A second objective of the present invention is to provide a production line including the above-described automatic edge-oiling machine.

[0006] To achieve the aforementioned first objective, the automatic edge-painting machine provided by the present invention includes an oil-brushing mechanism, which includes a first driving mechanism and an oil-brushing roller. The oil-brushing roller extends vertically, and the first driving mechanism drives the oil-brushing roller to rotate. The automatic edge-painting machine also includes a rotating device located on one side of the oil-brushing mechanism. The rotating device includes a second driving mechanism and a rotating table. The rotation axis of the rotating table is parallel to the oil-brushing roller. The second driving mechanism drives the rotating table to rotate, and the rotation direction of the rotating table is opposite to the rotation direction of the oil-brushing roller. The rotating table and the oil-brushing roller cooperate to convey forward along a first horizontal direction. In the conveying direction, the oil-brushing roller is located upstream of the rotating table. A pressing device includes a third driving mechanism and a guide wheel. The guide wheel is located above the rotating table. The third driving mechanism can drive the guide wheel to approach the rotating table. The projection center of the guide wheel is close to the oil-brushing roller in a second horizontal direction relative to the center of the rotating table. The projection center is the center of the projection of the guide wheel on the upper surface of the rotating table. The second horizontal direction intersects the first horizontal direction.

[0007] As can be seen above, the square product to be oiled is placed on the rotating table, and the third drive mechanism drives the guide wheel to press the product to be oiled. The rotating table and the brush roller rotate simultaneously, and the projection center of the guide wheel is set off-center relative to the center of the rotating table. Therefore, when the guide wheel presses the product towards the rotating table, the friction between the guide wheel and the brush roller and the product, as well as the friction and centrifugal force between the rotating table and the product, work together to make the product move forward along the first horizontal direction, so that the brush roller can oil one side of the product. When one side of the product is finished, the product deflects with the rotating table, and the brush roller continues to oil the other side of the product until all sides are finished, thus automatically oiling the product.

[0008] A further option is to arrange the rotary table and the brushing roller at intervals in the first horizontal direction, with the brushing roller located upstream of the rotary table in the conveying direction.

[0009] As can be seen above, the rotating table and the brushing roller are arranged at intervals in the first horizontal direction, and the brushing roller is located on the upstream side of the rotating table. This eliminates the need for an additional support on the upstream side of the brushing roller to prevent the product to be oiled from deflecting, making the structure simpler, easier to install and produce, and saving costs.

[0010] A further proposed solution is that the axis of the guide wheel is parallel to the second horizontal direction, and the second horizontal direction is perpendicular to the first horizontal direction.

[0011] As can be seen from the above, the axis of the guide wheel is parallel to the second horizontal direction, and the second horizontal direction is perpendicular to the first horizontal direction, which can effectively reduce friction and wear.

[0012] A further embodiment includes a column and a connecting arm in which the clamping device is further comprising a guide wheel rotatably mounted on the first end of the connecting arm and the second end of the connecting arm hinged to the column; a third drive mechanism is located between the guide wheel and the column, and the third drive mechanism includes a spring, the restoring force of which forces the guide wheel closer to the rotary table.

[0013] As can be seen from the above, the spring not only enables the clamping guide device to press the product on the rotating table to be oiled, but also prevents the product from being damaged due to excessive pressure.

[0014] A further option is that the third drive mechanism also includes a cylinder, which drives the connecting arm to move below the connecting arm, and the connecting arm drives the guide wheel away from the rotary table.

[0015] As can be seen from the above, the cylinder is designed so that the guide wheel can automatically release the product after the edge is finished, making it easy to remove the finished product.

[0016] A further embodiment is that the connecting arm includes a first rod and a second rod arranged intersecting each other. The two ends of the first rod are respectively connected to the column and the second rod. The first rod is hinged to the column, and the guide wheel is located at the end of the second rod away from the first rod.

[0017] A further embodiment is that the clamping device also includes a fine-tuning mechanism, which includes a slide groove and an adjusting bolt. The slide groove extends along the length of the second rod and is located at one end of the second rod. The first adjusting bolt passes through the slide groove and connects the first rod and the second rod.

[0018] As can be seen from the above, the position of the guide wheel against the upper surface of the rotating platform can be adjusted by the setting of the adjusting bolt and the sliding groove.

[0019] A further option is that the rotary table includes a second rotating shaft and a placement platform, with the placement platform located at the top of the second rotating shaft, and the placement platform being made of rubber or silicone.

[0020] As can be seen above, using a placement platform made of rubber or silicone can increase the friction between the rotating platform and the product, preventing the product from sliding off the movement trajectory and resulting in incomplete edge painting.

[0021] A further option is to extend the lower end of the brush roller below the upper surface of the rotary table.

[0022] As can be seen above, the lower end of the brushing roller extends below the upper surface of the rotating table, ensuring that the edge of the product to be oiled is in full contact with the brushing roller.

[0023] To achieve the second objective mentioned above, the present invention provides a production line including any one of the above-mentioned automatic edge-oiling machines.

[0024] In summary, the edge-oiling machine provided by this invention can complete the automatic edge-oiling process according to a predetermined trajectory, greatly saving manpower. Attached Figure Description

[0032] See Figures 1 to 4 The automatic edge-oiling machine provided in this embodiment includes a base 1, an edge-oiling device 2, a pressing device 3, and a rotating device 4. The edge-oiling device 2, the pressing device 3, and the rotating device 4 are all mounted on the base 1. The edge-oiling device 2 includes a mounting frame 20, an oil tank 21, an oil brushing mechanism 5, and an oil delivery mechanism 6. The oil tank 21, the oil delivery mechanism 6, and the oil brushing mechanism 5 are all mounted on the mounting frame 20. The oil delivery mechanism 6 includes an oil delivery plate 60 and a fourth driving mechanism 61. The axis of the oil delivery plate 60 extends along a first horizontal direction. The fourth driving mechanism 61 drives the oil delivery plate 60 to rotate relative to the mounting frame 20 around the axis of the oil delivery plate 60. The upper end of the oil delivery plate 60 is located outside the oil tank 21, and the lower end of the oil delivery plate 60 extends into the oil tank 21. An annular oil delivery groove 600 extending circumferentially along the oil delivery plate 60 is provided on the peripheral wall of the oil delivery plate 60.

[0033] The oil brushing mechanism 5 includes a first drive mechanism 51 and an oil brushing roller 50. The axis of the oil brushing roller 50 extends vertically. The first drive mechanism 51 drives the oil brushing roller 50 to rotate around the axis of the oil brushing roller 50. The lower end of the oil brushing roller 50 extends vertically and passes through the oil delivery groove 600.

[0034] See Figures 1 to 7 The rotating device 4 is located on one side of the brushing mechanism 5. The rotating device 4 includes a second drive mechanism 41 and a rotating platform 40. The axis of the rotating platform 40 is parallel to the axis of the brushing roller 50. The rotating platform 40 is located on the side of the brushing roller 50 away from the oil delivery plate 60. The second drive mechanism 41 drives the rotating platform 40 to rotate relative to the base 1 around its axis. The rotation direction of the rotating platform 40 is opposite to the rotation direction of the brushing roller 50. The rotating platform 40 and the brushing roller 50 are arranged at intervals in a first horizontal direction. The first horizontal direction is perpendicular to the second horizontal direction.

[0035] The rotary table 40 includes a second rotating shaft 400 and a placement platform 401. The placement platform 401 is located at the top of the second rotating shaft 400. The lower end face of the brushing roller 50 extends below the upper end face of the placement platform 401. The placement platform 401 is made of materials such as silicone or rubber. Optionally, the lower end face of the brushing roller 50 is tangent to the upper end face of the rotary table 40.

[0036] The clamping device 3 includes a third drive mechanism 33 and a clamping mechanism. The clamping mechanism includes a guide wheel 32, a column 30, a fine-tuning mechanism, and a connecting arm. The column 30 is mounted on the base and extends vertically. The connecting arm includes a first rod 310 and a second rod 311 that intersect each other. The two ends of the first rod 310 are respectively connected to the column 30 and the second rod 311. The first rod 310 is hinged to the column 30. The second rod 311 extends along a first horizontal direction, and the first rod 310 extends along a second horizontal direction. The guide wheel 32 is mounted on the base. The second rod 311 is located at the end furthest from the first rod 310. The third drive mechanism 33 is located between the guide wheel 32 and the column 30. The third drive mechanism 33 includes a spring 330 and a cylinder 331, which are spaced apart. The two ends of the spring 330 in the extension direction are connected to the base 1 and the lower surface of the first rod 310, respectively. The restoring force of the spring 330 forces the guide wheel 32 close to the upper surface of the placement platform 401. When the guide wheel 32 abuts against the upper surface of the placement platform 401, the spring 330 is in a stretched state. Optionally, when the product is placed on the upper surface of the placement platform 401, the spring 330 abuts against the surface of the product away from the placement platform 401, at which time the spring is in a stretched state.

[0037] Cylinder 331 is located below the connecting arm. The drive rod 332 of cylinder 331 drives the connecting arm to move, causing the guide wheel 32 to move away from the rotary table 40. Optionally, when cylinder 331 is in its normal state, the drive end of the drive rod 332 is adjacent to or located below the lower surface of the first rod 310. When cylinder 331 is in its extended state, the drive rod 332 drives the first rod 310 to rotate relative to the column 30. The projection center of the guide wheel 32 is near the brush roller 50 on a second horizontal plane relative to the center of the rotary table 40. Here, the projection center is the projection center of the peripheral wall of the guide wheel 32, which can effectively abut against the product, on the upper surface of the rotary table 40. The guide wheel 32, the rotary table 40, and the brush roller 50 cooperate to move forward along the first horizontal direction. In the conveying direction, the brush roller 50 is located upstream of the rotary table 40. Optionally, the rotary table and the brushing roller are not spaced apart in the first horizontal direction. The oiling device also includes a support roller mounted on the mounting frame. The support roller and the brushing roller are arranged sequentially in the first horizontal direction. The support roller, guide wheel, rotary table and the brushing roller work together to convey the product forward in the first horizontal direction.

[0038] See Figure 6The fine-tuning mechanism includes a first sliding groove 3110 and a first adjusting bolt 312. The first sliding groove 3110 is located at one end of the second rod 311 and extends along the length of the second rod 311. The first adjusting bolt 312 passes through the first sliding groove 3110 and connects the first rod 310 and the second rod 311. When the first adjusting bolt 312 is loosened, the second rod 311 can rotate relative to the first rod 310 and can also move along the length of the second rod 311. After adjustment, the first adjusting bolt 312 is tightened.

[0039] See Figures 1 to 4 A second slide groove 210 is provided on the side wall of the oil tank 21. The second slide groove 210 extends vertically and a second adjusting bolt 211 passes through the second slide groove 210. The second adjusting bolt 211 connects the oil tank 21 to the mounting bracket 20. When the second adjusting bolt 211 is loosened, the oil tank 21 can move vertically relative to the second adjusting bolt 211.

[0040] The mounting bracket 20 is also equipped with an oil-blocking mechanism 7, which includes a third rotating shaft 71 and an oil-blocking plate 70 disposed on the third rotating shaft 71. The third rotating shaft 71 extends vertically, and the oil-blocking plate 70 is adjacent to the brushing roller 50 in the horizontal direction and forms a gap with the brushing roller 50. An adjustment knob 72 is provided on the third rotating shaft 71, and the size of the gap is adjusted by rotating the third rotating shaft 71 through the adjustment knob 72.

[0041] It should be noted that the above are only preferred embodiments of the present invention, but the design concept of the invention is not limited thereto. Any non-substantial modifications made to the present invention using this concept also fall within the protection scope of the present invention.
