Description

Technical Field

[0001] The invention relates to the technical field of anti-counterfeiting film conveying, and in particular to a double-sided printed anti-counterfeiting film positioning and conveying device. Background Art

[0002] Double-sided printing anti-counterfeiting film refers to a special anti-counterfeiting material with anti-counterfeiting information or patterns printed on both sides of the film material. This technology is usually used in product packaging, labels and documents that require high security and are difficult to copy. During the printing process of double-sided printing anti-counterfeiting film, it is necessary to ensure that the patterns or information on both sides can be accurately aligned. Any position deviation will affect the quality and anti-counterfeiting effect of the product. Through precise positioning and conveying, it can be ensured that the anti-counterfeiting film is in the correct position every time it is printed, thereby achieving high-precision matching.

[0003] The traditional method of conveying anti-counterfeiting film is to use a motor to drive the winding drum to rotate, and then pull the anti-counterfeiting film on the unwinding drum for conveying. This method can ensure that the anti-counterfeiting film is evenly placed in the printing equipment in a relatively short time. However, as the anti-counterfeiting film is continuously rolled into the winding drum, the outer diameter of the winding drum will gradually increase. Since the winding drum will form a larger arc length when rotating at the same angle, this will increase the variation of the conveying position of the anti-counterfeiting film, which in turn affects the uniform distribution of the anti-counterfeiting mark on the film. Summary of the invention

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figure 1-Figure 10As shown, the present invention is a double-sided printed anti-counterfeiting film positioning and conveying device, comprising a support member 1 and a reeling mechanism 2 arranged on one side of the support member 1, an equidistant conveying mechanism 4 for conveying an anti-counterfeiting film 3 is installed on one side of the support member 1; the equidistant conveying mechanism 4 comprises a clamping mechanism 41, a reciprocating translation mechanism 42, a distance control component 43 and a locking mechanism 44, a slideway 5 for sliding the clamping mechanism 41 is provided through the support member 1, the clamping mechanism 41 comprises a U-shaped plate 411, the U-shaped plate 411 is slidably connected to the slideway 5, the reciprocating translation mechanism 42, the distance control component 43 and the locking mechanism 44 are installed at the side wall of the support member 1, and the reciprocating translation mechanism 42 It is used to drive the clamping mechanism 41 to move back and forth along the slide 5. The distance measurement control component 43 is used to measure the moving distance of the clamping mechanism 41. The distance measurement control component 43 includes a controller 431, a first baffle 432 and a first displacement sensor 433. The first baffle 432 is connected to the bottom of the U-shaped plate 411. The first displacement sensor 433 is installed on the side wall of the support 1 through a first bracket, and the detection end of the first displacement sensor 433 corresponds to the position of the first baffle 432. The controller 431 is installed on the side wall of the support 1. The locking mechanism 44 is linked to the clamping mechanism 41, and the locking mechanism 44 is used to control the discharge of the anti-counterfeiting film 3.

[0021] It should be noted that, when in use, the distance measurement control component 43 is used to accurately control the distance of each advance and retreat of the reciprocating translation mechanism 42, and the clamping mechanism 41 can control the clamping of the anti-counterfeiting film 3. When the anti-counterfeiting film 3 is clamped, the interlocking locking mechanism 44 can synchronously unlock the discharge of the anti-counterfeiting film 3, so that the reciprocating translation mechanism 42 can drive the clamped anti-counterfeiting film 3 to advance a set distance, and then the clamping mechanism 41 cancels the clamping of the anti-counterfeiting film 3. At this time, the interlocking locking mechanism 44 will lock the discharge of the anti-counterfeiting film 3, and the reciprocating translation mechanism 42 can drive the clamping mechanism 41 to retreat and reset, and then re-clamp the anti-counterfeiting film 3, and repeat this process, so as to achieve equidistant transportation of the anti-counterfeiting film 3, effectively improving the accuracy of the transportation position.

[0022] like Figure 2-Figure 4 As shown, the clamping mechanism 41 also includes a cylinder 412, an upper clamping plate 413 and a lower clamping plate 414. The lower clamping plate 414 is fixedly installed in the U-shaped plate 411, and the upper surface of the lower clamping plate 414 is in contact with the lower surface of the anti-counterfeiting film 3. The cylinder 412 is installed on the top of the U-shaped plate 411, and the output end of the cylinder 412 is connected to the upper clamping plate 413. The upper clamping plate 413 corresponds to the lower clamping plate 414, and the upper clamping plate 413 is located above the anti-counterfeiting film 3.

[0023] It should be noted that protective pads are provided on the facing sides of the upper clamping plate 413 and the lower clamping plate 414. The protective pads can be made of silicone material, but are not limited to silicone material. The use of protective pads can not only improve the clamping effect, but also prevent the anti-counterfeiting film 3 from being clamped. By starting the cylinder 412 to drive the upper clamping plate 413 to move downward, the anti-counterfeiting film 3 can be stably clamped in cooperation with the lower clamping plate 414.

[0024] like Figure 3 and Figure 5 As shown, the unwinding mechanism 2 includes a discharge drum 21 rotatably mounted on one side of the support member 1, a winding drum 22, a winding motor 23, a first guide roller 24 and two second guide rollers 25. The anti-counterfeiting film 3 on the discharge drum 21 is connected to the winding drum 22 after bypassing the first guide roller 24 and the two second guide rollers 25. The two second guide rollers 25 are horizontally distributed, and the U-shaped plate 411 is located between the two second guide rollers 25. The winding motor 23 is used to drive the winding drum 22 to rotate.

[0025] It should be noted that a double-sided printing device 15 is provided between the two second guide rollers 25, which is used to perform double-sided printing on the transported anti-counterfeiting film 3. The anti-counterfeiting film 3 on one of the second guide rollers 25 enters through the feed port of the double-sided printing device 15, then extends out from the discharge port to bypass the other second guide roller 25, and finally connects to the winding drum 22. The clamping mechanism 41 (such as Figure 2 As shown in the figure, the anti-counterfeiting film 3 is pulled between the two second guide rollers 25 at an equal distance each time, so that the distance moved by the anti-counterfeiting film 3 each time in the double-sided printing device 15 remains consistent, thereby achieving uniform printing of the anti-counterfeiting film 3.

[0026] like Figure 6-Figure 8 As shown, a docking piece 6 is coaxially inserted in the discharge drum 21 and the winding drum 22, and the docking piece 6 includes an insertion rod 61, a limit key 62, a blocking cover 63, a threaded protrusion 64, a threaded sleeve 65 and a limit block 66. The discharge drum 21 and the winding drum 22 are coaxially penetrated by a through hole 7 matching the insertion rod 61, and a key groove 8 corresponding to the limit key 62 is opened at the hole wall of the through hole 7. The blocking cover 63 and the threaded protrusion 64 are coaxially connected to the two ends of the insertion rod 61 respectively, the threaded sleeve 65 is threadedly connected to the threaded protrusion 64, and a plurality of limit blocks 66 are circumferentially connected to the outer wall of the threaded sleeve 65.

[0027] It should be noted that the cross-section of the blocking cover 63 is larger than the cross-section of the insertion rod 61, so that when the discharge drum 21 and the winding drum 22 are sleeved on the insertion rod 61, their ends can fit with the blocking cover 63 to form a limit. The limit key 62 cooperates with the key slot 8, so that the blocking cover 63 can drive the discharge drum 21 and the winding drum 22 to rotate synchronously when rotating. Loosen the threaded sleeve 65 to separate it from the threaded protrusion 64, and the discharge drum 21 and the winding drum 22 can be disassembled. After the discharge drum 21 and the winding drum 22 are sleeved on the insertion rod 61, the threaded sleeve 65 is installed on the threaded protrusion 64, and the limit block 66 is fit with the ends of the discharge drum 21 and the winding drum 22 to complete the limit installation.

[0028] like Figure 2-Figure 4 As shown, the reciprocating translation mechanism 42 includes a connecting plate 421, a servo motor 422 and a screw rod 423. The connecting plate 421 is fixedly mounted on the side wall of the U-shaped plate 411, and the connecting plate 421 is threadedly connected to the screw rod 423. The servo motor 422 is connected to the side wall of the support member 1 through the mounting plate. The screw rod 423 is coaxially connected to the output end of the servo motor 422. The servo motor 422, the first displacement sensor 433 and the cylinder 412 are all electrically connected to the controller 431.

[0029] It should be noted that the rotational freedom of the U-shaped plate 411 is limited by the slide 5, so that when the servo motor 422 drives the screw rod 423 to rotate, the connecting plate 421 can drive the U-shaped plate 411 to slide along the slide 5. When the servo motor 422 is controlled to move in the opposite direction, the U-shaped plate 411 can slide and reset along the slide 5; the controller 431 is electrically connected to the servo motor 422, the first displacement sensor 433 and the cylinder 412 respectively. If the distance of each positioning and conveying of the anti-counterfeiting film 3 is a, the first displacement sensor 433 is used to detect the movement of the first baffle 432. When the movement is a, the detected signal is sent to the controller 431, thereby controlling the cylinder 412 to cancel the clamping, and controlling the servo motor 422 to rotate in the opposite direction to drive the U-shaped plate 411 back to the initial position. Similarly, when it is detected that the U-shaped plate 411 is reset, the cylinder 412 is controlled to clamp, and the servo motor 422 is controlled to drive the U-shaped plate 411 to move.

[0030] like Figure 1 and Figure 6-Figure 8 As shown, a pin shaft 9 is coaxially connected to the blocking cover 63 corresponding to the discharge drum 21 , the pin shaft 9 passes through the support member 1 , and the pin shaft 9 is rotatably connected to the support member 1 , and the blocking cover 63 corresponding to the winding drum 22 is coaxially connected to the output shaft of the winding motor 23 .

[0031] It should be noted that a bearing for rotational support is installed between the pin shaft 9 and the support member 1. When the rotational freedom of the pin shaft 9 is not locked, pulling the anti-counterfeiting film 3 can make the unloading drum 21 adaptively rotate to realize unloading. Starting the winding motor 23 can drive the winding drum 22 to rotate, which is convenient for winding up the anti-counterfeiting film 3 after double-sided printing.

[0032] like Figure 4 , Figure 6 and Fig. 9 As shown, the locking mechanism 44 includes an L-shaped pressure column 442 with a first through groove 441, a cross column 443, a gear 444, an arcuate tooth block 445, a sliding column 447 with a first spring 446, a pulley 448, a pull rope 449 and an I-shaped column 4411 with a second spring 4410, the gear 444 is mounted on the end of the pin 9, the arcuate tooth block 445 is meshed with the top of the gear 444, the cross column 443 is mounted on the side wall of the support member 1, and the sliding column 447 and the I-shaped column 4411 are both slidably penetrated through the cross column 44 3 is provided, and the bottom end of the sliding column 447 is connected to the arc-shaped tooth block 445, two pulleys 448 are installed on the side wall of the support member 1 located above the horizontal column 443, the pull rope 449 passes through the pulley 448 and is respectively connected to the sliding column 447 and the top of the I-shaped column 4411, one end of the L-shaped pressure column 442 is connected to the upper clamping plate 413, and the L-shaped pressure column 442 is slidably sleeved with the I-shaped column 4411 through the first through groove 441, and the side wall of the U-shaped plate 411 is provided with a second through groove 10 for the L-shaped pressure column 442 to pass through.

[0033] It should be noted that when the upper clamp 413 is pressed down and clamped, it drives the L-shaped pressure column 442 to descend synchronously, and the L-shaped pressure column 442 presses the I-shaped column 4411 to slide down and compress the second spring 4410. With the guidance of the pulley 448, the pull rope 449 can pull the sliding column 447 upward and compress the first spring 446, which can drive the arc-shaped tooth block 445 to disengage from the gear 444, thereby canceling the limitation on the rotational freedom of the pin shaft 9, so that the clamping mechanism 41 can smoothly pull the anti-counterfeiting film 3 for transportation. When the anti-counterfeiting film 3 is transported in place, the upper clamp 413 rises and resets. Under the reset force of the first spring 446 and the second spring 4410, the arc-shaped tooth block 445 can be re-engaged with the gear 444 and reset, and the anti-counterfeiting film 3 can be locked for discharge.

[0034] like Figure 2 and Fig.10 As shown, a third through groove 11 is provided on the side wall of the support member 1 for the output shaft of the winding motor 23 to pass through, and a buoyancy support assembly 12 is installed at the bottom of the winding motor 23. The buoyancy support assembly 12 includes a water tank 121, a float 122 and a support column 123. The water tank 121 is installed on the support member 1, and the float 122 is immersed in the water in the water tank 121. The support column 123 slides through the top of the water tank 121, and the two ends of the support column 123 are respectively connected to the winding motor 23 and the float 122.

[0035] It should be noted that the third through slot 11 can be used to make the winding motor 23 and the support member 1 slide relative to each other, and the winding motor 23 and the winding drum 22 (such as Figure 5 The gravity of the winding motor 23 and the winding drum 22 is partially supported by the buoyancy support assembly 12. In this embodiment, the total gravity of the winding motor 23 and the winding drum 22 is greater than the buoyancy generated by the float 122. However, the pulling force generated by the winding motor 23 and the winding drum 22 after being balanced by the float 122 will not damage the anti-counterfeiting film 3.

[0036] like Figure 2-Figure 3 As shown, a second baffle 13 is installed on the side wall of the support column 123 near the top, and a second displacement sensor 14 is correspondingly arranged above the second baffle 13. The second displacement sensor 14 is connected to the side wall of the support column 123 through a second bracket, and the second displacement sensor 14 and the winding motor 23 are both electrically connected to the controller 431.

[0037] It should be noted that, since the winding motor 23 will adaptively drop when the anti-counterfeiting film 3 is pulled and transported, in order to keep the anti-counterfeiting film 3 in a tensioned state, the transported anti-counterfeiting film 3 needs to be correspondingly rolled up, and the second displacement sensor 14 cooperates with the second baffle 13 to detect the distance. When it is detected that the second baffle 13 drops and there is no distance fluctuation in a short time, the drop distance will not cause the second baffle 13 and the water tank 121 (such as Fig.10 If the anti-counterfeiting film 3 is touched, a signal is sent to the controller 431 to control the winding motor 23 to rewind the anti-counterfeiting film 3 until the second baffle 13 rises and resets to the initial position.

[0038] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
