[0048] The side-printing equipment and printing production line according to embodiments of the present invention are described below with reference to the accompanying drawings.

[0049] Reference Figure 1 The present invention aims to provide an embodiment of a side-printing device, which can be part of a printing production line. Therefore, the present invention also aims to provide an embodiment of a printing production line, which includes a material conveying device 5.

[0050] In this embodiment, the side printing device includes a feeding module 1, a discharging module 2, and a printing module 3 located between the feeding module 1 and the discharging module 2.

[0051] For feeding module 1, feeding module 1 is used to provide the product to be printed;

[0052] The feeding module 1 includes a first conveying mechanism and a second conveying mechanism, which are arranged sequentially along the product conveying direction.

[0053] The first conveying mechanism mainly includes a feeding conveyor belt to receive products from the previous process.

[0054] The second conveying mechanism also includes a feeding conveyor belt. The second conveying mechanism can work intermittently to stagger the products and meet the printing requirements.

[0055] In some specific embodiments of this utility model, the second conveying mechanism may further include two sets of side limiting roller groups 11 located at the top of the feeding conveyor belt. The feeding conveyor belt is used to support and convey the product to be printed. The space between the two sets of side limiting roller groups 11 allows the product to be printed to pass through, thereby making the product's position in the left and right directions of the feeding conveyor belt accurate, reducing subsequent adjustments, so as to carry out printing smoothly.

[0056] As for the unloading module 2, it is used to receive the printed products.

[0057] Specifically, the unloading module 2 includes a third conveying mechanism and a fourth conveying mechanism, both of which include an unloading conveyor belt to transport the products to be printed.

[0058] The fourth conveying mechanism is located on the discharge side of the third conveying mechanism. The conveying speed of the fourth conveying mechanism can be different from that of the third conveying mechanism to change the gap between products and meet the feeding requirements.

[0059] In some specific embodiments of this utility model, the third conveying mechanism may include a screening device 10 disposed on one side of the unloading conveyor belt. The screening device 10 is capable of pushing out defective printed products from the unloading conveyor belt, and the pushing direction of the screening device 10 is perpendicular to the conveying direction of the unloading conveyor belt.

[0060] In some specific embodiments of this utility model, a sensor for detecting the product position can be provided on the receiving side of the third conveying mechanism, thereby reasonably determining the position of defective products and enabling the screening device 10 to accurately push out defective products.

[0061] Reference Figure 2 For the printing module 3, the printing module 3 is used to print on the product to be printed. The printing module 3 includes a printing device 4 and a material conveying device 5.

[0062] The printing device 4 includes a corona device 7, a printhead 8, and a curing device 9 arranged in a horizontal direction.

[0063] The corona device 7 is used to energize the surface of the product to be printed, so as to roughen the surface and facilitate ink adhesion.

[0064] In some specific embodiments of this utility model, the printing device 4 may further include a distance detection device 6, which is located on the material receiving side of the corona device 7. The distance detection device 6 is used to detect the surface of the product to be printed in order to determine whether the surface of the product to be printed meets the printing requirements.

[0065] If the surface to be printed does not meet the printing requirements, the printing device 4 will not work and will not print.

[0066] In some specific embodiments of this utility model, the printing device 4 may include a printhead 8 moisturizing device, with the printhead 8 located inside the printhead 8 moisturizing device to protect the printhead 8.

[0067] In some specific embodiments of this utility model, a nozzle cleaning device can be provided above the nozzle 8 to facilitate cleaning of the nozzle 8.

[0068] In some specific embodiments of this utility model, the printing device 4 may also include a visual inspection device to visually inspect the printing effect, so as to promptly screen out defective products, and also to facilitate the detection of abnormalities, stop printing in time, and make adjustments.

[0069] When the surfaces to be printed are located on both sides of the product along its length, the printing device 4 of this invention is located on one side of the product, eliminating the need to stand the product upright.

[0070] Meanwhile, due to manufacturing or design reasons, the surface to be printed is not in an upright state. Therefore, the distance between the various positions of the surface to be printed and the printhead 8 is not the same, making it difficult to guarantee the printing quality.

[0071] Therefore, in this embodiment, the material feeding device 5 includes a clamp for fixing the product. The clamp includes a lifting component 240 and a clamping component 250. The lifting component 240 can lift the first side of the product to adjust the side of the product to tilt. The clamping component 250 is used to clamp the second side of the product to position the printing position. The second side and the first side are located on opposite sides of the product.

[0072] In summary, this utility model, by setting up a lifting component 240, can lift the first side of the product, causing the product to tilt, thereby adjusting the state of the surface to be printed so that the state of the surface to be printed meets the printing requirements, for example, the surface to be printed is parallel to the printhead 8.

[0073] This utility model, by setting up a clamping component 250, can clamp and fix the second side of the product, thereby ensuring that the position of the product's printing surface meets the requirements, such as the distance between the printing surface and the printhead 8, ensuring the printing force, meeting the printing needs, and ensuring the printing quality.

[0074] In some specific embodiments of this utility model, the lifting component 240 may have two lifting support points to smoothly lift the first side and prevent the product from tipping over.

[0075] In some specific embodiments of this utility model, the lifting assembly 240 may include a lifting block, a screw that drives the lifting block to lift, a first bevel gear located at one end of the screw, a second bevel gear meshing with the first bevel gear, a third bevel gear coaxial with the second bevel gear, and a fourth bevel gear meshing with the third bevel gear. The fourth bevel gear is driven to rotate by a motor. In this way, the height of the first clamp 110 and the second clamp 150 can be reduced, thereby reducing the risk of the first clamp 110 and the second clamp 150 touching each other.

[0076] The motor of the lifting component 240 can also be hidden inside the product, making full use of space.

[0077] Therefore, referring to Figure 3 The present invention aims to provide an embodiment of a material conveying device 5, which is part of the printing module 3 of a side-printing device.

[0078] Compared with existing technologies, the material conveying device 5 of this utility model can stabilize products and meet printing requirements, while also having a high operating speed and improving production efficiency. Furthermore, the side printing equipment of this utility model, by applying the aforementioned material conveying device 5, can achieve side printing, ensuring printing quality, and also has high printing production efficiency.

[0079] Reference Figure 3 In this embodiment, the material conveying device 5 mainly includes a feeding mechanism 220, a discharging mechanism 230, and a material conveying section.

[0080] For ease of understanding, Figure 3 The corona device 290 for the printing section is also shown.

[0081] The feeding mechanism 220 is used to move the product from the feeding conveyor line to the clamp of the conveying section, and the feeding mechanism 220 is used to move the product from the clamp of the conveying section to the unloading conveyor line, so as to realize automated conveying, reduce labor, and reduce costs.

[0082] In some specific embodiments of the present invention, the feeding mechanism 220 may include a lifting and translating feeding clamp that can place the product in the first clamp 110 and the second clamp 150.

[0083] It is easy to understand that by setting up a lifting and translating loading clamp in this embodiment, it is also convenient to quickly place the product on the first clamp 110 by lifting and translating. At the same time, it also allows the material conveying part and the loading conveyor line to be set closer, making the side printing equipment structure compact and helping to reduce the footprint.

[0084] In some specific embodiments of this utility model, the translation direction of the feeding clamp can be unidirectional to simplify the configuration of the feeding mechanism 220 and reduce costs.

[0085] Reference Figure 4 In some specific embodiments of this utility model, the unloading mechanism 230 may include an unloading clamp that can be lifted and translated, which can remove the product from the first clamp 110 and the second clamp 150.

[0086] It is easy to understand that by setting the unloading mechanism 230 to refer to the loading mechanism 220, this embodiment can reduce the specifications of parts and reduce the difficulty of maintenance.

[0087] Therefore, it can also be used Figure 4 Go and understand the structural details of the feeding mechanism 220.

[0088] In some specific embodiments of this utility model, the material conveying device 5 may include an loading clamp and a unloading clamp, which are used to clamp the product along the length direction of the product.

[0089] It is easy to understand that this embodiment improves material handling stability and prevents the product from flipping by clamping it along the length of the product.

[0090] In some specific embodiments of this utility model, the loading and unloading clamps can include suction cups, which can increase the contact area and facilitate the use of vacuum to lift the product, reduce hard contact, and avoid damage to the product surface.

[0091] For the material transportation section, refer to Figure 3 , Figure 5 and Figure 6 The material handling section includes a first material handling mechanism 100 and a second material handling mechanism 140.

[0092] The first material conveying mechanism 100 includes a first clamp 110 for fixing the product, a first translation component 120 for installing the first clamp 110, and a first lifting component 130 for connecting the first translation component 120.

[0093] The second material conveying mechanism 140 is disposed opposite to the first material conveying mechanism 100. The second material conveying mechanism 140 includes a second clamp 150 for fixing the product, a second translation component 160 for installing the second clamp 150, and a second lifting component 170 for connecting the second translation component 160.

[0094] In terms of arrangement, the first clamp 110 and the second clamp 150 are located between the first material conveying mechanism 100 and the second material conveying mechanism 140.

[0095] During operation, the movement trajectories of the first fixture 110 and the second fixture 150 overlap, so that the products of the first fixture 110 and the second fixture 150 are sequentially placed in the processing position.

[0096] In summary, by setting up a first material conveying mechanism 100, the first clamp 110 and the second clamp 150 can be translated and lifted, realizing the cyclic reciprocating motion of the first clamp 110 and the second clamp 150. This not only enables continuous product supply but also reduces the number of clamps and lowers manufacturing costs.

[0097] This invention includes a first clamp 110 for fixing the product, a first translation component 120 for mounting the first clamp 110, and a first lifting component 130 connecting the first translation component 120 in the first material conveying mechanism 100; and a second material conveying mechanism 140 includes a second clamp 150 for fixing the product, a second translation component 160 for mounting the second clamp 150, and a second lifting component 170 connecting the second translation component 160. Therefore, compared with the prior art, the first clamp 110 and the second clamp 150 are precisely and stably positioned and will not move arbitrarily, thus meeting the needs of product printing.

[0098] Meanwhile, the first material conveying mechanism 100 includes a first translation component 120 and a first lifting component 130, and the second material conveying mechanism 140 includes a second translation component 160 and a second lifting component 170, which also makes the first material conveying mechanism 100 and the second material conveying mechanism 140 simple in structure and low in manufacturing cost.

[0099] Meanwhile, the first material conveying mechanism 100 and the second material conveying mechanism 140 will not produce displacement perpendicular to the translation direction of the first translation component 120 and the second translation component 160. Therefore, it is convenient to arrange the printing mechanism on one side of the first translation component 120 or the second translation component 160. Furthermore, it makes it difficult for the position of the fixture and the printing part to change. Therefore, the distance between the product and the printing part is consistent, ensuring the printing quality.

[0100] Meanwhile, the movements of the first fixture 110 and the second fixture 150 are independent of each other. Therefore, the time that the first fixture 110 and the second fixture 150 stay at each station of the printing section can be different, which can meet the needs of the printing process and avoid the production efficiency of the printing process being limited by the station with the longest time consumption.

[0101] In other words, when the first fixture 110 is at the most time-consuming position, the second fixture 150 can move multiple times to complete other processing steps without needing to move synchronously with the first fixture 110. Therefore, rapid production can be achieved and efficiency can be improved.

[0102] In some specific embodiments of this utility model, the first translation component 120 may include a first crossbeam 180 and a first transverse component 190 that moves along the first crossbeam 180. The first transverse component 190 is provided with a first longitudinal arm 200, and a first clamp 110 is provided at the top of the first longitudinal arm 200.

[0103] It is easy to understand that, in this embodiment, by setting a first crossbeam 180 and a first transverse member 190 that moves along the first crossbeam 180, the length of the first crossbeam 180 can ensure that the first transverse member 190 has a long travel distance, thus meeting the needs of the first fixture 110 for transfer at each station in the printing section.

[0104] In some specific embodiments of this utility model, the first lifting assembly 130 may include two first columns 210, which are located at both ends of the first crossbeam 180, and the first columns 210 are slidably connected to both ends of the first crossbeam 180.

[0105] It is easy to understand that by setting two first columns 210, the two ends of the first crossbeam 180 can be supported, avoiding the first crossbeam 180 from being subjected to force in a cantilever manner, and avoiding the weight of the first crossbeam 180 from affecting the stability of the material conveying mechanism. At the same time, it can also reduce the strength requirements of the first crossbeam 180 and reduce manufacturing costs.

[0106] In some specific embodiments of this utility model, the first column 210 can be provided with a screw drive structure for driving the first crossbeam 180 to rise and fall. The screw drive structure includes a motor, a screw driven by the motor to rotate, and a screw sleeve that engages the screw. The screw sleeve is fixed to the first crossbeam 180, which can realize the precise rise and fall of the first crossbeam 180 and improve the printing position accuracy.

[0107] In some specific embodiments of this utility model, the translation drive structure of the first transverse member 190 can be referenced to the screw drive structure.

[0108] In some specific embodiments of this utility model, the translation drive structure of the first transverse member 190 can include a gear and rack structure, eliminating the need for a long screw, reducing manufacturing difficulty and cost, and also reducing space occupation.

[0109] Reference Figure 6 In some specific embodiments of this utility model, the first clamp 110 may include a lifting component 240, which can lift the first side of the product to adjust the side tilt of the product.

[0110] It is easy to understand that, by setting up the lifting component 240, the first side of the product can be lifted, so that the side tilt of the product can be adjusted to match or adapt to the printing part, thereby ensuring the printing quality.

[0111] Due to the manufacturing process, most of the products are injection molded parts. The side of the product has a draft angle relative to the placement surface. That is, when the product is placed in the first fixture 110, the surface to be printed is tilted and not perpendicular to the corona device 290. As a result, the printed pattern will be deformed, affecting the printing quality.

[0112] In this embodiment, the lifting component 240 can be set to adjust the angle of the surface to be printed, so that the surface to be printed is perpendicular to the corona device 290, thereby improving or ensuring the printing quality.

[0113] In some specific embodiments of this utility model, the first clamp 110 may include a clamping assembly 250, which is used to clamp the second side of the product, and the second side and the first side are located on opposite sides of the product.

[0114] It is easy to understand that by setting the clamping component 250, this embodiment can also facilitate the positioning and fixing of the second side of the product, avoid raising the first side and causing unpredictable changes in the position of the product, avoid changes in the distance between the printing surface and the corona device 290 that exceed expectations, and avoid affecting the printing quality, such as the printing force.

[0115] In some specific embodiments of this utility model, the clamping assembly 250 may include a reference clamp 260 and a movable clamp 270. The reference clamp 260 and the movable clamp 270 are used to clamp the second side. The reference clamp 260 is used to abut the outer side of the second side, and the movable clamp 270 is used to abut the inner side of the second side.

[0116] It is easy to understand that by setting the reference clamp 260, the product can be accurately positioned, making the product position precise. The movable clamp 270 can move inside the product without increasing the space occupied, making the first clamp 110 compact and occupying little space.

[0117] In some specific embodiments of this utility model, the reference clamp 260 can be adjusted or tilted to correspond to the reference surface of the product.

[0118] In some specific embodiments of this utility model, the reference clamp 260 is connected to a first connecting rod, a second connecting rod hinged to the first connecting rod, and a third connecting rod connecting the connection between the first connecting rod and the second connecting rod. The third connecting rod is hinged to the cylinder rod of the cylinder.

[0119] Therefore, when the cylinder pushes the third link, it makes the first link and the second link lie in the same straight line to stably support the reference clamp 260.

[0120] In some specific embodiments of this utility model, the first link, the second link, and the third link can be divided into two groups to realize the two-point positioning reference clamp 260.
