Description

Technical Field

[0001] The present invention relates to a printing device, and more particularly to a plate facing printing device. Background Art

[0002] The plate surface finishing printing device is a device specially used for efficient printing on the surface of various plates. It can complete a large number of printing tasks in a short time to meet the needs of efficient production. The plate surfaces on the market usually have clear patterns and bright colors. The printing device adopts a modular setting, and the pattern module can be replaced according to actual printing needs. However, in actual use, it is found that more customers like randomized patterns. If the pattern module is made into a pattern shape, on the one hand, if the pattern module is not replaced after printing, the formed pattern will still have regularity. On the other hand, if the pattern module is continuously replaced, the printing efficiency will be greatly reduced. Therefore, a plate surface finishing printing device is needed, which can quickly print randomized patterns.

[0003] In view of the above reasons, how to quickly print randomized patterns is exactly the problem considered in this application. Summary of the invention

[0004] In view of the shortcomings of the prior art, a plate surface printing device is provided, which can quickly print random patterns.

[0005] To achieve the above-mentioned purpose, the following technical scheme is provided: a plate surface printing device, comprising a mounting frame, a support beam, a driving assembly, a positioning assembly and a printing assembly, wherein the support beam is mounted below the mounting frame, the driving assembly is connected to the printing assembly and both are mounted below the support beam, the positioning assembly is mounted on the side of the support beam, the positioning assembly is used to prevent the plate from detaching from the cross beam, the driving assembly is used to drive the printing assembly to realize the printing function, the printing assembly comprises a first positioning shell, a storage box, a supporting wheel, a transmission belt and printing particles, the first positioning shell is connected to the support beam, the storage box is fixedly connected to the first positioning shell and the opening faces the support beam, the supporting wheel is arranged in the storage box and is rotatably connected to the inner wall of the storage box, the transmission belt is connected to the supporting wheel, the transmission belt extends out of the opening of the storage box toward one side of the support beam, the printing particles are placed in the storage box, and the transmission belt is used to absorb the printing particles;

[0006] The printing particles are magnetic, and the printing component also includes a magnetic adsorption component and a scraping component. Multiple magnetic adsorption components are fixedly connected to the transmission belt. The magnetic adsorption component extends out of the opening of the storage box toward one end of the support beam. The scraping component is arranged in the storage box and is used to scrape the printing particles on the magnetic adsorption component.

[0007] In summary, the above technical solution has the following beneficial effects: when in use, the mounting frame can be installed on a set production line, and the support beam and other components are arranged under the mounting frame. After the plate moves to the support beam, the positioning component prevents the plate from falling off the beam. The movement of the plate can be achieved by other equipment on the production line. For example, the track used for movement is directly arranged under the support beam, thereby driving the plate to move. When the plate moves, the driving component will also start, thereby driving the printing component to start. When the printing component is performing a printing operation, the dye needs to be placed in a storage box in advance, and the printing particles in the storage box can fully contact with the dye. When the support wheel drives the transmission belt to move continuously, the magnetic adsorption part will adsorb the printing particles through magnetic force, and the adsorbed The attached printing particles are exposed from the opening of the storage box under the action of the transmission belt, and the printing particles are firmly connected to the magnetic adsorption part under the action of the magnetic force, so that irregular patterns can be formed by the movement of the plate and the action of the transmission belt during the printing operation. When the printing particles that have completed a printing operation enter the storage box again, they will not only be covered with dye again, but also be displaced in the process of being piled up with other printing particles, thereby changing the patterns that can be formed. In addition, they will be scraped off by the scraping part, thereby leaving the magnetic adsorption part. When the printing particles pass over the scraping part due to the action of the magnetic force and inertia, they will be adsorbed on the magnetic adsorption part again. At this time, the position of the printing particles has changed, thereby achieving the purpose of quickly printing random patterns.

[0008] The positioning component is a multifunctional component that needs to play the role of clamping the plate. After the plate is transported to the beam, it is controlled by the positioning component, and the positioning component itself can use mechanical claws and other structures to grasp the plate while driving the plate to move. Its main function is to prevent the plate from falling off the beam.

[0009] The printing component performs printing operations under the plate in the form of an inverted arch bridge. On the one hand, the storage box is set up to store the dye. Even if the dye drips during the printing process, it will return to the storage box, which can save resources and prevent the dye from dripping onto the plate surface to damage the formed texture, or dripping into the inside of the component to interfere with normal operation. On the other hand, even if there is a lot of local dye accumulation on the plate, because the surface is facing the ground, the excess dye will not spread around under the action of gravity, thereby destroying the formed texture, but forming a cone, which is convenient for subsequent processing;

[0010] The present invention sets a transmission belt as an operating unit for printing operations, sets a magnetic adsorption component and printing particles that can be separated from the magnetic adsorption component on the transmission belt as a printing unit, and sets a scraper to disrupt the adsorption position of the printing particles on the magnetic adsorption component, thereby achieving the purpose of quickly printing random patterns.

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The same parts are represented by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0021] Reference Figure 1-4As shown, the plate surface printing device includes a mounting frame 1, a support beam 2, a driving assembly 3, a positioning assembly 4 and a printing assembly 5. The support beam 2 is installed below the mounting frame 1. The driving assembly 3 is connected to the printing assembly 5 and both are installed below the support beam 2. The positioning assembly 4 is installed on the side of the support beam 2. The positioning assembly 4 is used to prevent the plate from detaching from the cross beam. The driving assembly 3 is used to drive the printing assembly 5 to realize the printing function. The printing assembly 5 includes a first positioning shell 51, a storage box 52, a support wheel 53, a transmission belt 54 and printing particles 55. The first positioning shell 51 is connected to the support beam 2. The storage box 52 is fixedly connected to the first positioning shell 51 and the opening faces the support beam 2. The support wheel 53 is provided in the storage box 52 and is rotatably connected to the inner wall of the storage box 52. The transmission belt 54 is connected to the support wheel 53. The transmission belt 54 extends out of the opening of the storage box 52 toward one side of the support beam 2. The printing particles 55 are placed in the storage box 52, and the transmission belt 54 is used to absorb the printing particles 55.

[0022] The printing particles 55 are magnetic, and the printing assembly 5 further includes a magnetic adsorption member 56 and a scraping member 57. The plurality of magnetic adsorption members 56 are fixedly connected to the transmission belt 54. The magnetic adsorption members 56 extend out of the opening of the storage box 52 toward one end of the support beam 2. The scraping member 57 is disposed in the storage box 52 and is used to scrape the printing particles 55 on the magnetic adsorption members 56.

[0023] When in use, the mounting frame 1 can be installed on a set production line, and the support beam 2 and other components are arranged under the mounting frame 1. After the plate moves to the support beam 2, the positioning component 4 prevents the plate from falling off the beam. The movement of the plate can be achieved by other equipment on the production line. For example, the track used for movement is directly arranged under the support beam 2, thereby driving the plate to move. When the plate moves, the driving component 3 will also start, thereby driving the printing component 5 to start. When the printing component 5 performs printing operations, the dye needs to be placed in the storage box 52 in advance, and the printing particles 55 in the storage box 52 can be fully in contact with the dye. When the support wheel 53 drives the transmission belt 54 to move continuously, the magnetic adsorption component 56 will adsorb the printing particles 55 through magnetic force, and the adsorbed printing particles 55 are on the transmission belt 54. The opening of the storage box 52 is exposed under the action of the magnetic force, and the printing particles 55 are firmly connected to the magnetic adsorption member 56 under the action of the magnetic force, so that irregular patterns can be formed by the movement of the plate and the action of the transmission belt 54 during the printing operation. When the printing particles 55 that have completed a printing operation enter the storage box 52 again, they will not only be covered with dye again, but also be displaced in the process of being piled up with other printing particles 55, thereby changing the patterns that can be formed. In addition, they will be scraped off by the scraping member 57, thereby leaving the magnetic adsorption member 56. When the printing particles 55 pass over the scraping member 57 due to the action of the magnetic force and inertia, they will be adsorbed on the magnetic adsorption member 56 again. At this time, the position of the printing particles 55 has changed, thereby achieving the purpose of quickly printing random patterns.

[0024] The positioning component 4 is a multifunctional component that needs to play the role of clamping the plate. After the plate is transported to the crossbeam, it is controlled by the positioning component 4, and the positioning component 4 itself can use a mechanical claw or other structure to grasp the plate and drive the plate to move. The main function of the positioning component 4 is to prevent the plate from falling off the crossbeam.

[0025] The printing component 5 performs printing operation on the bottom of the plate in the form of an inverted arch bridge. On the one hand, the storage box 52 is provided to store the dye. Even if the dye drips during the printing operation, it will return to the storage box 52, which can save resources and prevent the dye from dripping onto the plate surface to damage the formed texture or dripping into the inside of the component to interfere with normal operation. On the other hand, even if a large amount of dye is locally accumulated on the plate, because the surface faces the ground, the excess dye will not spread around under the action of gravity, thereby destroying the formed texture, but will form a cone, which is convenient for subsequent processing;

[0026] The present invention sets a transmission belt 54 as an operating unit for the printing operation, sets a magnetic adsorption component 56 and printing particles 55 that can be separated from the magnetic adsorption component 56 on the transmission belt 54 as a printing unit, and sets a scraper 57 to disrupt the adsorption position of the printing particles 55 on the magnetic adsorption component 56, thereby achieving the purpose of quickly printing random patterns.

[0027] Furthermore, the scraping member 57 is arranged in an inverted triangle shape in cross section, and the tip thereof is close to the magnetic adsorption member 56;

[0028] Since the scraper 57 is mainly used to separate the printed particles 55 from the magnetic adsorption part 56, it is necessary to set the tip close to the magnetic adsorption part 56. The inverted triangle shape is set to form a downward slope when the two tips are close to the magnetic adsorption part 56. In this way, no matter which direction the support wheel 53 moves, it can play a scraping role and can also prevent the separated printed particles 55 from being adsorbed on the magnetic adsorption part 56 again in a short time, thereby better ensuring the randomization of the formed texture.

[0029] Further, the driving assembly 3 includes a second positioning shell 31, a first motor 32, a transmission shaft 33 and a transmission wheel 34. The second positioning shell 31 is fixedly connected to the side of the first positioning shell 51, the second positioning shell 31 is connected to the support beam 2, the second motor 352 is fixedly connected to the inner wall of the second positioning shell 31, the first motor 32 is connected to the transmission shaft 33, the transmission shaft 33 passes through the first positioning shell 51 and the second positioning shell 31 and extends into the storage box 52, the transmission wheel 34 is fixedly connected to the transmission shaft 33 and is arranged inside the storage box 52, and the transmission wheel 34 is meshed and connected with the transmission belt 54;

[0030] The second positioning shell 31 and the first positioning shell 51 can form a complete inverted arch bridge structure, so as to facilitate the printing operation of the printing component 5, and the first motor 32 provides power for the printing component 5. When the first motor 32 starts, it drives the transmission shaft 33 to rotate, and the transmission shaft 33 drives the transmission wheel 34 to rotate, and the transmission wheel 34 controls the operation of the transmission belt 54.

[0031] Furthermore, the support beam 2 is also fixedly connected with a toothed guide rail 21 and a first track 22 arranged parallel to the toothed guide rail 21, and the driving assembly 3 further includes a moving assembly 35 and a first slider 36, the moving assembly 35 is used to drive the second positioning shell 31 to move along the toothed guide rail 21, one end of the first slider 36 is slidably connected to the first track 22, and the other end of the first slider 36 is fixedly connected to the second positioning shell 31;

[0032] The moving assembly 35 includes a rotating gear 351, a second motor 352 and an auxiliary gear 353. The second motor 352 is fixedly connected to the second positioning shell 31. One end of the rotating gear 351 is connected to the second motor 352. The other end of the rotating gear 351 is meshed with the toothed guide rail 21. One end of the auxiliary gear 353 is rotatably connected to the second positioning shell 31. The other end of the second positioning shell 31 is meshed with the toothed guide rail 21.

[0033] The second motor 352 can drive the rotating gear 351 to rotate. Since the second motor 352 is fixedly connected to the second positioning shell 31, and the rotating gear 351 is also meshed with the toothed guide rail 21, the second positioning shell 31 can be driven to move along the direction of the toothed guide rail 21 by starting the second motor 352, that is, the printing component 5 and the driving component 3 can both move along the support beam 2, and the toothed guide rail 21 and the first track 22 are arranged in parallel, so that the moving directions of the rotating gear 351 and the first slider 36 are parallel, and the position between the rotating gear 351 and the first slider 36 is relatively far, and the auxiliary gear 353 can prevent the second positioning shell 31 from rotating or deflecting in the moving direction during the moving process, and can also make the moving process of the second positioning shell 31 more stable;

[0034] When the board can be moved by other components, the printing operation can be completed even if the printing component 5 cannot move. However, when printing on boards that are difficult to move, such as solid wood boards, the effect of printing random patterns cannot be achieved. Therefore, a moving component 35 is provided so that the printing component 5 can also perform mobile printing.

[0035] Furthermore, the support beam 2 is also provided with a second track 23 arranged parallel to the toothed guide rail 21, the second track 23 is slidably connected with a second slider 37 fixedly connected to the second positioning shell 31, and the first slider 36 and the second slider 37 are respectively arranged on both sides of the rotating gear 351;

[0036] In order to further improve the stability of the movement of the printing assembly 5 and ensure the quality of the texture, a second track 23 and a second slider 37 are provided, and the first slider 36 and the second slider 37 are respectively provided on both sides of the rotating gear 351, which can reduce the possibility of the printing assembly 5 tilting.

[0037] Furthermore, the positioning assembly 4 includes a first receiving beam 41, a second receiving beam 42 and a receiving baffle 43. The first receiving beam 41 and the second receiving beam 42 are respectively fixedly connected to the two ends of the supporting beam 2, and the receiving baffle 43 is detachably connected to the supporting beam 2.

[0038] Since the support beam 2 itself has no bottom support for the plate, a first supporting beam 41 and a second supporting beam 42 are set as the bottom support of the plate, and the first supporting beam 41 and the second supporting beam 42 are fixedly connected to the two ends of the support beam 2 respectively. The length of the plate may be shorter than the support beam 2. In this case, the weight of the plate is usually lighter, so a detachable supporting baffle 43 can be used as a temporary supporting component.

[0039] Furthermore, a dust collecting device is installed on the side of the first connecting beam 41 facing the supporting beam 2. The plate is passed through the first connecting beam 41 before the printing operation is performed. At this time, the dust collecting device can absorb the particulate dust that affects the printing.

[0040] Furthermore, a magnetic recovery device is installed on the side of the second supporting beam 42 facing the supporting beam 2. After the printing of the plate is completed, it passes through the second supporting beam 42 and then leaves. Since small fragments may be generated due to the friction between the printing particles 55, these fragments will affect the subsequent processing of the plate. Therefore, a magnetic recovery device is set to absorb these small magnetic fragments.

[0041] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
