Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of labels, and more particularly to an inkjet device for flexible labels. Background Art
[0002] A label inkjet device is a device specially designed for printing labels or stickers on various materials. It uses inkjet printing technology to spray ink directly onto the surface of the substrate to form the required pattern, text or code; while a flexible label inkjet device is mainly used for flexible substrates such as film, paper and cloth. The reason why these materials can be regarded as representatives of flexible substrates is that they not only cover a wide range of uses, but also each has unique advantages and can adapt to the specific requirements of different industries.
[0003] In the process of existing inkjet devices operating on flexible substrates, the flexible substrates are first taken out from the storage. When the flexible substrates are stacked and stored, the bottom material will bear the weight of the upper material, especially at the edges, which is prone to forming indentations or wrinkles. If there are wrinkles or creases on the surface of the flexible substrate, and the temperature and humidity conditions cause the material to expand or contract, especially in paper and certain plastic films, this dimensional change may cause wrinkles. When there are wrinkles or creases on the surface of the flexible substrate, the distance between the inkjet print head and the material will change, resulting in inaccurate ink injection position and uneven printing, such as deformed and blurred text or patterns. Therefore, we propose a flexible label inkjet device to solve this problem. Summary of the Invention

[0015] The beneficial effects of the present invention are: 1. By driving the two transverse plates to move intermittently toward each other, when the transverse plates stop moving horizontally, multiple telescopic rods operate synchronously to drive the transverse plates to move back and forth. During the descent of the transverse plates, the leveling wheels abut against the flexible substrate and cannot move downward, thereby driving the bottom of the turntable to swing upward with the fixed axis as the axis, thereby driving the top of the turntable to swing downward, thereby compressing the torsion spring. The compressed torsion spring provides resistance to the upward swing of the bottom of the turntable, causing friction between the leveling wheel and the flexible substrate. The direction of the friction force is the same as the horizontal direction of the movement of the leveling wheel, causing the fabric to gradually stretch in the front and back directions. During the up and down reciprocating movement of the transverse plates, the wrinkles and creases on the flexible substrate are gradually reduced.
[0016] 2. The degree of tension on the flexible substrate can be controlled by controlling the up and down movement of the vertical moving plate. At the same time, the electric push rod drives multiple lifting plates to move upward synchronously, so that multiple balls extend above the processing table to press the flexible substrate. The synchronous pressing of multiple balls can provide uniform support force, help further flatten the material, and further eliminate small wrinkles or creases that still exist in the slightly tensioned state.

DETAILED DESCRIPTION
[0019] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that these embodiments are discussed to enable those skilled in the art to better understand and implement the subject matter described herein. The functions and arrangements of the elements discussed may be varied without departing from the scope of protection of this specification. Various examples may omit, substitute, or add various processes or components as needed. In addition, features described with respect to some examples may also be combined in other examples.
[0020] Reference Figure 1-10 A flexible label inkjet device includes a processing table 1, an adsorption mechanism 4, an inkjet mechanism 2, two flattening mechanisms 3 and two tensioning mechanisms 5. A built-in groove is provided on the top of the processing table 1. The adsorption mechanism 4 is arranged in the built-in groove and is used to firmly adsorb the flexible substrate on the processing table 1. The flattening mechanism 3 is horizontally slidably installed on the top of the processing table 1 and is used to flatten the flexible substrate in the front and back directions and press and fix it. Side grooves 108 are provided on the left and right sides of the processing table 1. The tensioning mechanisms 5 are arranged in the corresponding side plate grooves. The two tensioning mechanisms 5 cooperate to flatten the flexible substrate in the left and right directions.
[0021] In this embodiment, the inkjet mechanism 2 includes two guide rail frames 201, which are respectively fixedly mounted on the front and rear sides of the processing table 1. A transverse guide rail 202 is provided on the top of the guide rail frame 201, and a support seat is slidably mounted on the transverse guide rail 202. The same longitudinal guide rail 203 is fixedly mounted between the two support seats. The outer sliding sleeve of the longitudinal guide rail 203 is provided with a sliding member, and a vertical guide rail 204 is provided on one side of the sliding member. An inkjet head 205 is fixedly mounted on one side of the vertical guide rail 204. The inkjet head 205 is configured as a MEMS inkjet print head, and its nozzle diameter is at the micron level, so that a single print head can integrate thousands of nozzles, greatly improving the printing resolution. MEMS inkjet technology highlights the advantages of non-contact printing, avoids physical damage to soft substrates, and ensures high-quality printing while protecting material integrity.
[0022] During specific use, the vertical guide rail 204 drives the inkjet head 205 to move downward and be placed above the flexible substrate while maintaining a suitable distance therefrom. The transverse guide rail 202 and the longitudinal guide rail 203 cooperate to drive the inkjet head 205 to move on the XY axis to perform inkjet operation.
[0023] Example 1 In this embodiment, a dual-axis motor 101 is fixedly installed in the middle position of the front side of the processing table 1, and threaded rods 102 are fixedly installed on the two output shafts of the dual-axis motor 101. A moving block 103 is threadedly installed on the outer side of the threaded rod 102. The flattening mechanism 3 includes a transverse plate 301, and the front and rear sides of the transverse plate 301 are fixedly connected to ear plates 302. A telescopic rod 303 is provided at the bottom of the ear plate 302. The bottom end of the telescopic rod 303 is fixedly connected to the top of the corresponding moving block 103, and the top end of the telescopic rod 303 is fixedly connected to the corresponding ear plate 302. The bottom of the processing table 1 is fixedly connected, and a limit plate 104 is fixedly installed on the rear side of the processing table 1. Two sliders 105 are slidably installed on the outer side of the limit plate 104. The sliders 105 are fixedly connected to the corresponding telescopic rods 303. Through the cooperation of the bidirectional motor, the threaded rod 102 and the moving block 103, the two transverse plates 301 are driven to intermittently move toward the side close to each other, each time moving a certain distance until the two transverse plates 301 are moved to the center position close to the processing table 1. Each pause time is used for the telescopic rod 303 to drive the transverse plates 301 to reciprocate up and down.
[0024] In this embodiment, a plurality of pressure wheel mechanisms are provided on both sides of the transverse moving plate 301, and the plurality of pressure wheel mechanisms are symmetrically arranged front to back. The pressure wheel mechanism includes a fixed shaft 304, one end of the fixed shaft 304 is fixedly connected to one side of the corresponding transverse moving plate 301, and a rotating sleeve on the outer side of the fixed shaft 304 is provided with a rotating plate 305, and a leveling wheel 306 is rotatably installed on one side of the rotating plate 305, and the outer fixed sleeve of the leveling wheel 306 is provided with a rubber sleeve.
[0025] In this embodiment, the pressure wheel mechanism also includes multiple short plates 307, one side of the short plate 307 is fixedly connected to one side of the corresponding transverse plate 301, and a bent rod 308 is fixedly installed on the top of the short plate 307. The rotating plate 305 is slidably sleeved on the outside of the corresponding bent rod 308. The same torsion spring 309 is fixedly connected between the rotating plate 305 and the corresponding short plate 307. The torsion spring 309 is wound around the outside of the corresponding bent rod 308. The bent rod 308 guides and limits the rotation of the rotating plate 305, and the torsion spring 309 limits the swing of the rotating plate 305.
[0026] When in use, the two transverse plates 301 are driven to intermittently move toward one side approaching each other through the cooperation of the bidirectional motor, the threaded rod 102 and the moving block 103. When the transverse plate 301 stops moving horizontally, multiple telescopic rods 303 operate synchronously to drive the transverse plate 301 to move back and forth. During the descending process of the transverse plate 301, the leveling wheel 306 abuts against the flexible substrate and cannot move downward, thereby driving the bottom of the rotating plate 305 to swing upward with the fixed shaft 304 as the axis, thereby driving the top of the rotating plate 305 to swing downward, thereby compressing the torsion spring 309. The compressed torsion spring 309 provides resistance to the upward swing of the bottom of the rotating plate 305, so that friction is generated between the leveling wheel 306 and the flexible substrate. The direction of the friction is the same as the horizontal direction of the movement of the leveling wheel 306, so that the cloth is gradually stretched in the front and back directions. During the reciprocating up and down movement of the transverse plate 301, the wrinkles and creases on the flexible substrate are gradually reduced, and the gap between the two transverse plates 301 is close to improve the uniformity of flattening.
[0027] Example 2 In this embodiment, the adsorption mechanism 4 includes a box body 401, which is fixedly installed in the built-in groove. A plurality of adsorption holes 402 are provided on the top inner wall of the box body 401, and the plurality of adsorption holes 402 are arranged in an array with equal intervals. A plurality of air guide holes are provided on the rear side of the box body 401, and a connecting hole connected to the air guide hole is provided on the rear inner wall of the built-in groove. The air guide holes and the connecting holes are used together for an external vacuum pump to perform vacuum operation on the box body 401.
[0028] In this embodiment, the adsorption hole 402 is conical, and several lifting plates 403 are vertically slidably installed in the box body 401. A plurality of spring rods 404 are fixedly installed on the top of the lifting plate 403. The top of the spring rod 404 is fixedly connected to a sphere 405. The sphere 405 is slidably installed in the corresponding adsorption hole 402 to control the opening and closing of the adsorption hole 402. A bottom groove 106 is provided at the bottom of the processing table 1, and a plurality of support frames 107 are fixedly installed at the bottom of the bottom groove 106. Two electric push rods 406 are fixedly installed on the bottom inner wall of the support frame 107. The electric push rods 406 are fixedly and sealedly installed on the bottom inner wall of the box body 401, and the top of the electric push rods 406 is fixedly connected to the bottom of the corresponding lifting plate 403.
[0029] It should be noted that the electric push rod 406 drives the multiple balls 405 to move vertically through the cooperation with the lifting plate 403, and the up and down movement of the balls 405 is used to open and close the adsorption holes 402. Due to the elasticity of the spring rod 404, the balls 405 can tightly block the small ends of the adsorption holes 402; and the three lifting plates 403 are controlled separately, and the multiple adsorption holes 402 can be opened and closed in different areas. This not only saves energy consumption of the vacuum system, but also closes the adsorption holes 402 to the inkjet area through regional adsorption, and adsorbs the non-inkjet area to prevent the adsorption force from causing the flexible substrate to deform at the holes of the adsorption holes 402, thereby causing the label to be distorted.
[0030] During specific use, the wrinkles and creases of the flexible substrate after being flattened by the flattening mechanism 3 have been significantly improved. The box body 401 is then evacuated by a vacuum pump, and the flexible substrate is effectively fixed on the processing table 1 through multiple adsorption holes 402 to ensure that it is flat and wrinkle-free.
[0031] Example 3 In this embodiment, the tensioning mechanism 5 includes a guide wheel 501, a clamping frame 502 and a mounting plate 519. The front and rear ends of the guide wheel 501 are fixedly connected to the front and rear inner walls of the corresponding side groove 108 respectively. The clamping frame 502 is vertically slidably installed in the corresponding side groove 108. A plurality of connecting plates 503 are horizontally slidably installed on the inner wall of one side of the clamping frame 502. The same trapezoidal block 504 is fixedly installed on one side of the multiple connecting plates 503 on the same side. The same clamping plate 505 is fixedly installed on the other side of the connecting plate 503, and multiple return springs 506 are fixedly installed between the trapezoidal block 504 and the corresponding clamping frame 502. An extension plate 507 is fixedly installed on one side of the clamping frame 502, and multiple guide rods 508 are slidably installed on the extension plate 507. The bottom end of the guide rod 508 is fixedly connected to the bottom inner wall of the corresponding side groove 108, and multiple support springs 509 are fixedly connected between the extension plate 507 and the bottom inner wall of the side groove 108.
[0032] In this embodiment, the two mounting plates 519 are fixedly connected to the left and right sides of the processing table 1 respectively, and a screw rod 510 is rotatably installed at the middle position of the top of the mounting plate 519, and a vertical moving plate 511 is threadedly installed on the outer side of the screw rod 510, and vertical plates 512 are fixedly installed on the left and right sides of the top of the vertical moving plate 511. A wedge plate 513 is fixedly installed on one side of the vertical plate 512, and the inclined surface of the wedge plate 513 is slidably connected to the inclined surface of the corresponding trapezoidal plate, and a driving plate 514 is fixedly installed on one side of the vertical plate 512. A bottom plate 515 is fixedly installed at the bottom of the clamping frame 502, and the bottom plate 515 is slidably sleeved on the outer side of the corresponding vertical plate 512 and cooperates with the driving plate 514.
[0033] In this embodiment, a servo motor 516 is fixedly installed on the top of the mounting plate 519 on the left, and the output shaft of the servo motor 516 is fixedly connected to the screw rod 510 on the left. The outer sides of the two screw rods 510 are fixedly sleeved with pulleys, and the same belt 517 is installed on the two pulleys for transmission. Two directional plates 518 are fixedly installed on the top of the mounting plate 519, and the vertical moving plate 511 is slidably sleeved on the outer sides of the corresponding two directional plates 518. The two screw rods 510 are driven to rotate synchronously through the cooperation of the servo motor 516, the pulley and the belt 517, thereby driving the vertical moving plate 511 and the vertical plate 512 to move downward synchronously.
[0034] During specific use, for some flexible substrates that still have obvious wrinkles and creases after being flattened in Example 1, their two ends are naturally dropped into the clamping frame 502, and the cooperation of the servo motor 516, the pulley and the belt 517 drives the two screw rods 510 to rotate synchronously, thereby driving the vertical moving plate 511 and the vertical plate 512 to move downward synchronously, and the vertical plate 512 drives the inclined surface of the wedge plate 513 to move downward along the inclined surface of the trapezoidal block 504, thereby squeezing the trapezoidal block 504 to move toward the side close to the clamping frame 502, thereby driving the clamping plate 505 to move to one side to clamp the flexible substrate, and the vertical plate 512 continues to move downward until the driving plate 514 abuts against the bottom plate 515, thereby driving the two clamping frames 502 to move downward synchronously, and then synchronously driving the two ends of the flexible substrate to move downward synchronously, tightening the flexible substrate in the left and right directions, helping to further eliminate wrinkles and creases.
[0035] It is particularly noted that the degree of tension on the flexible substrate can be controlled by controlling the up and down movement of the vertical moving plate 511. At this time, the electric push rod 406 in Example 2 can be used to drive multiple lifting plates 403 to move upward synchronously, so that multiple balls 405 are extended to the processing table 1 to press the flexible substrate. The synchronous pressing of multiple balls 405 can provide uniform support force to help further flatten the material, especially for those cases where there are still small wrinkles or creases in a slightly tightened state. Compared with relying solely on tension, pressing can apply continuous pressure on the surface of the material, reducing the rebound phenomenon caused by the elasticity of the material; since moderate pressure is applied through multiple points instead of relying solely on tension, this method can effectively avoid excessive stretching or deformation of the material, especially for more fragile or sensitive materials. Multiple balls 405 can better adapt to irregular shapes or textured material surfaces, providing more uniform and stable support without causing local stress concentration.
[0036] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all embodiments. However, obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
