Description

Technical Field

[0001] The utility model relates to the technical field of tinplate can printing, and more specifically to a tinplate can printing device. Background Art

[0002] Tinplate cans, commonly known as iron cans or iron boxes, are cans made of tinplate. The iron on the surface of the tinplate can is coated with tin to protect it. Generally, for the sake of exquisite packaging, the surface of the tinplate can is processed by printing or printing to improve the appearance of the tinplate can. Tinplate printing also uses the physical properties of water and ink repelling each other. With the help of printing pressure, the printing plate image is transferred to the tinplate through the rubber cloth, which belongs to the principle of lithographic offset printing.

[0003] At present, when printing on tinplate can materials, if the position of the tinplate can material is uneven, it will be printed directly, which may cause a small amount of printing surface area of ​​the tinplate can material to be wasted, and it may need to be cut later, resulting in a certain cost waste. In addition, in the existing process, intense friction will occur between the roller and the tinplate can material, and the continuous friction will cause static electricity to be generated. Due to the influence of static electricity, the subsequent printing ink on the tinplate can material surface becomes uneven. Moreover, since the tinplate can is made of metal material, the generation of static electricity can easily cause dust to accumulate on the printing surface of the tinplate can, affecting the stability of printing. For this reason, this scheme proposes a tinplate can printing device. Utility Model Content

[0013] 3. Beneficial effects:

[0014] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects:

[0015] The utility model has a reasonable design. First, the tinplate can is adsorbed on the suction cup part on one side of the transfer platform and placed on the surface of the transfer platform. Before that, the cylinder causes the multiple telescopic ends to be located above the transfer platform under pneumatic operation, thereby causing the side ends of the tinplate can material to be on the same horizontal plane before printing. Then, the position fine-tuning component moves back and forth horizontally, causing the side ends of the tinplate can material to be simultaneously flat, thereby ensuring the synchronization of subsequent printing and avoiding material waste.

[0016] Then, as the position of the tinplate can material is adjusted, the suction cup component places the tinplate can material on the surface of the conveyor belt, and prompts the positioning component to move down and press it on the surface of the tinplate can material to ensure the stability of the subsequent tinplate can material in printing and the flatness of the surface;

[0017] At the same time, during this period, the anti-static component is placed on the surface of the positioning component, so that when the tinplate can material rotates with the friction between the roller after the conveyor belt is started, its static electricity can be conducted by the anti-static component, avoiding the tinplate can material from generating static electricity, making it difficult for dust in the air to adhere to the tinplate can material, ensuring that the ink is more uniform during the subsequent printing of the tinplate can material, and ensuring the printing quality.

Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0032] In this utility model, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," "provided with," "provided on," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; or internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on specific circumstances. Example

[0033] See also Figure 1-4, a tinplate can printing device, including a transfer platform 1, the front and rear sides of the transfer platform 1 are provided with adjustment holes 2, the interior of the adjustment hole 2 is slidably installed with a position fine-tuning component 3, the upper left end of the transfer platform 1 is provided with a plurality of longitudinally arranged positioning holes 4, the bottom of the transfer platform 1 is provided with a cylinder 5, and the multiple telescopic ends of the cylinder 5 are respectively located between the inner walls of each positioning hole 4, a printing press 6 is provided on the left side of the transfer platform 1, and a connecting plate 7 is fixedly connected between the printing press 6 and the transfer platform 1, a conveyor belt 8 is installed on the inner bottom end of the printing press 6, a positioning component 9 is installed on the right end of the printing press 6, and the positioning component 9 is located on the side of the conveyor belt 8. The side end of the printing press 6 is also provided with an anti-static component 10, and one end of the anti-static component 10 is in contact with the positioning component 9.

[0034] During use of this solution, in order to ensure that the position distribution of existing tinplate cans during printing is more uniform and flat, and that the tinplate can materials are not prone to excessive static electricity due to friction between the rollers, thereby reducing errors during printing and the phenomenon of dust adhering to the surface of the tinplate can materials, in this embodiment; first, one side of the transfer platform 1 adsorbs the tinplate can on the suction cup and places it on the surface of the transfer platform 1. Before that, the cylinder 5, under pneumatic operation, prompts the multiple telescopic ends to be located above the transfer platform 1, thereby prompting the tinplate can materials to be at the same horizontal plane before printing, and then the position fine-tuning component 3 is moved back and forth to prompt the side ends of the tinplate can materials to ensure flatness at the same time, thereby ensuring the synchronization of subsequent printing and avoiding material waste;

[0035] In this embodiment, the tinplate can material placed on the surface of the transfer platform 1 can be placed as one tinplate can material or two tinplate can materials. In the case of one tinplate can material, the position of both sides thereof can be adjusted synchronously by the position fine-adjusting component 3, while in the case of two tinplate can materials, the position can be adjusted on both sides of the position fine-adjusting component 3. The applicability can be adjusted according to the specific situation.

[0036] Then, as the position of the tinplate can material is adjusted, the suction cup member places the tinplate can material on the surface of the conveyor belt 8, and prompts the positioning component 9 to move down and press it on the surface of the tinplate can material to ensure the stability of the subsequent tinplate can material in printing and the flatness of the surface;

[0037] At the same time, during this period, the anti-static component 10 is placed on the surface of the positioning component 9, so that when the tinplate can material rotates with the friction between the conveyor belt 8 and the roller after it is started, its static electricity can be conducted by the anti-static component 10, thereby avoiding the tinplate can material from generating static electricity, making it difficult for dust in the air to adhere to the tinplate can material, ensuring that the ink is more uniform during the subsequent printing of the tinplate can material, and ensuring the printing quality.

[0038] See also Figure 1-2The position fine-tuning component 3 includes an adjustment block 31 slidably installed between the inner walls of the adjustment hole 2, and the bottom side end of the adjustment block 31 is fixedly connected to a transmission sleeve 32. The bottom of the transfer platform 1 is fixedly connected to a box body 33, and a positioning groove 34 is provided at the side end of the box body 33. A bidirectional threaded rod 35 is rotatably connected between the inner walls of the positioning groove 34, and the screw teeth on both sides of the bidirectional threaded rod 35 are inserted between the inner walls of the transmission sleeve 32. A motor 36 is installed at the rear end of the box body 33, and the output end of the motor 36 is fixedly connected to one end of the bidirectional threaded rod 35.

[0039] During use of this solution, after the tinplate can material is placed on the surface of the transfer platform 1, the personnel drives the motor 36 to cause the bidirectional threaded rod 35 to rotate. Since the transmission sleeve 32 is sleeved on the screw thread surface of the bidirectional threaded rod 35 and is limited by the positioning groove 34, when the bidirectional threaded rod 35 rotates, its transmission sleeve 32 converts the rotational motion into linear motion, so that the adjustment block 31 is relatively close to the inner wall of the adjustment hole 2, thereby adjusting the side end position of the placed tinplate can material to maintain flatness during printing.

[0040] See also Figure 1-3 The positioning assembly 9 includes two symmetrically distributed receiving holes 91 opened on the right side of the printing machine 6. A telescopic rod 92 is installed between the inner walls of the receiving holes 91. A roller 93 is inserted between the inner walls of the telescopic rod 92. A positioning frame 94 is fixedly connected to the upper end of the printing machine 6, and the positioning frame 94 is located on the outside of the roller 93.

[0041] During use of this solution, when the tinplate can material is placed on the surface of the conveyor belt 8, the personnel can drive the telescopic rod 92 to move downward until the roller 93 contacts the surface of the tinplate can material, and then the personnel drives the conveyor belt 8 to transmit, prompting the tinplate can material to be transported to the inside of the printing machine 6. At the same time, the roller 93 continuously rotates on the surface of the tinplate can material, pressing the top of the tinplate can material to ensure stability during subsequent printing.

[0042] See also Figure 1-4 The anti-static component 10 includes a positioning block 1001 fixedly connected to the right end of the printer 6, and the outer end of the positioning block 1001 is fixedly connected to a support shaft 1002, and the support shaft 1002 is in the same horizontal plane as the roller 93. The outer end of the support shaft 1002 is sleeved with a ring 1003, and the side end of the ring 1003 is sleeved with an electrostatic release belt 1004. A conductive ring 1005 and a nut 1006 are provided on one side surface of the electrostatic release belt 1004. The conductive ring 1005, the electrostatic release belt 1004, and the ring 1003 are fixedly connected by through bolts and nuts 1006. One end of the conductive ring 1005 is electrically connected to a grounding bar.

[0043] More specifically: the side end of the electrostatic release belt 1004 is fixedly connected to a positioning sleeve 1007, a slide groove 1008 is provided at the outer end of the positioning block 1001 on one side, a slider 1009 is slidably connected between the inner walls of the slide groove 1008, a spring 1010 is fixedly connected between the slider 1009 and the slide groove 1008, and the side end of the slider 1009 is fixedly connected to a limiting rod 1011, and one end of the limiting rod 1011 passes through the inner walls of the positioning sleeve 1007.

[0044] During the use of this solution, before printing the tinplate can material, the personnel can fix the ring 1003, the electrostatic release belt 1004, and the conductive ring 1005 with bolts, and then put the ring 1003 on the surface of the support shaft 1002, and at the same time pull the limit rod 1011 upward to stretch the spring 1010, and then pass the limit rod 1011 through the interior of the positioning sleeve 1007, and finally, slide the ring 1003 to the center position of the support shaft 1002 and press the spring 1010 against the center of the support shaft 1002. Under the reset characteristic of 010, the limiting rod 1011 pulls down the static release belt 1004, causing the static release belt 1004 to adhere to the surface of the transmission shaft on one side of the roller 93. Subsequently, when the roller 93 moves downward, the static release belt 1004 can still be in constant contact with the surface of the transmission shaft of the roller 93 under the rebound reset of the spring 1010. Therefore, the static electricity generated on the surface of the roller 93 is conducted to the grounding bar through the action of the static release belt 1004 and the conductive ring 1005, thereby eliminating static electricity.

[0045] The problem that static electricity is generated by continuous friction between the existing tinplate can material and the roller, resulting in uneven printing ink, and the subsequent generation of static electricity easily causes dust to accumulate on the surface of the tinplate can material, is solved, which greatly improves the stability and quality of tinplate can material printing.

[0046] The above-mentioned embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, which all fall within the scope of protection of the utility model. Therefore, the scope of protection of the utility model patent shall be based on the attached claims.
