Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, specifically to a printing equipment for multi-angle printing of workpieces. Background Technology

[0002] Printing equipment is a device used to print patterns, text, or logos on the surface of various workpieces. Through workpiece printing, patterns, trademarks, or designs can be printed on the surface of products to enhance their appearance and attractiveness. Printing equipment can also add important operating instructions, usage methods, warning signs, and other information to products to help consumers use products correctly and ensure safety. Some workpiece printing equipment uses inks and coatings that can enhance the wear resistance, oxidation resistance, and corrosion resistance of product surfaces. Chinese Patent Publication No. CN222628903U discloses a printing device suitable for multi-angle printing, relating to the field of printing equipment technology. The device includes a base plate, a support frame fixedly connected to the outer surface of the base plate, a sliding table fixedly connected to the outer surface of the support frame, and the sliding table fixedly connected to the outer surface of the base plate. This utility model has a reasonable design structure. Through the cooperation of a lead screw, a sliding block, a linkage table, and a movable seat, the lead screw can drive the sliding block to move when rotating, and the sliding block can drive the linkage table to move. Two servo drives are installed inside the movable seat, which can clamp and rotate the product. The number of linkage tables can be increased according to the number of printing stages per cycle. Furthermore, the servo drives, controlled by a central control panel, ensure that the rotation amplitude of the rear movable seat is equal to that of the front movable seat, allowing the entire printing table to print multiple products simultaneously during the downward printing process, thus solving the problem of only being able to print one product per cycle. The aforementioned patent mentions that the printing equipment uses a servo drive inside the movable seat to move and rotate the workpiece to achieve multi-angle printing. However, the existing structure lacks a precise transmission structure for workpiece angle adjustment and lacks intermediate transmission components that can improve angle control accuracy, making it difficult to control the angle adjustment error within the range required for high-precision printing. Furthermore, the clamping and limiting method of the movable seat for the workpiece is not optimized for rotational printing scenarios. During the workpiece's rotation with the movable seat, insufficient clamping stability can easily cause the workpiece to wobble, affecting the printing angle accuracy and the positional accuracy of the pattern on the workpiece surface, resulting in printing deviations and failing to meet the requirements of high-precision printing. Therefore, we propose a printing equipment for multi-angle printing of workpieces. Utility Model Content

[0003] To address the aforementioned issues, a printing device for multi-angle printing on workpieces is provided. An adjustment mechanism drives a mounting plate to rotate, which in turn causes the mounting plate to rotate the workpiece via a workstation. The adjustment mechanism's speed reducer has a self-locking function, effectively preventing reverse rotation of the load and improving the control accuracy of angle adjustment. A drive mechanism then drives a clamping plate to stably hold the workpiece, avoiding positional deviations caused by workpiece rotation and swaying. This solves the technical problem that while the printing device relies on a servo drive within the movable seat for multi-angle printing, it lacks precise transmission components, and the clamping is not adapted to the rotation scenario, easily leading to workpiece swaying and printing deviations, making it difficult to meet high-precision requirements.

[0004] To address the problems of existing technologies, this utility model provides a printing device for multi-angle printing of workpieces, including a printing machine body with a mounting groove on the printing machine body; a mounting plate rotatably mounted on the side of the printing machine body near the mounting groove; a workstation seat detachably mounted on the mounting plate; a clamping plate mounted on the workstation seat; an adjustment component for driving the mounting plate to rotate between the printing machine body and the mounting plate; and a drive mechanism for driving the clamping plate to achieve displacement between the workstation seat and the clamping plate.

[0005] Preferably, the adjustment component includes a speed reducer and a first power component; the speed reducer is fixedly mounted on the printing press body, and the output end of the speed reducer is fixedly connected to the working end of the mounting plate; the first power component is fixedly connected to the input end of the speed reducer, and the first power component is used to provide power for the rotation of the mounting plate.

[0006] Preferably, the drive mechanism includes a connecting pad and a second power component; the connecting pad is fixedly connected to the inner side of the clamping plate; the second power component is detachably fixedly connected to the workstation seat.

[0007] Preferably, the drive mechanism further includes a first guide component, a transmission component, and a second guide component; the first guide component is disposed between the workstation and the clamping plate, and the first guide component is used to assist the clamping plate in linear movement; the transmission component is disposed between the first guide component and the second power component, and the transmission component is used to transmit the power of the second power component to the first guide component; the second guide component is disposed between the workstation and the transmission component, and the second guide component is used to assist the transmission component in performing motion actions along a preset trajectory.

[0008] Preferably, the first guide assembly includes a slider and a groove; the slider is fixedly connected to the lower side of the clamping plate; the groove is formed on the side of the workstation seat near the slider, and the groove slides in cooperation with the slider.

[0009] Preferably, the transmission assembly includes a first connecting rod, a second connecting rod, a universal joint, and a connecting plate; the first connecting rod is disposed in the slide groove, and one end of the first connecting rod is fixedly connected to the slider; the second connecting rod is disposed at the end of the first connecting rod away from the slider, and both ends of the second connecting rod are respectively fixedly connected to the working end of the universal joint, and the working end of the universal joint at one end of the second connecting rod is fixedly connected to the first connecting rod; the connecting plate is disposed at the end of the second connecting rod away from the first connecting rod, and the connecting plate is fixedly connected to the working end of the universal joint of the second connecting rod away from the first connecting rod.

[0011] The advantages of this utility model compared to the prior art are: 1. The adjustment mechanism drives the mounting plate to rotate, which in turn causes the mounting plate to drive the workpiece to rotate via the workstation seat. The speed reducer of the adjustment mechanism has a self-locking function, which can effectively prevent the load from rotating in the opposite direction. At the same time, it can accurately reduce the output speed of the first power component, improve the control accuracy of angle adjustment, and solve the technical problems of insufficient angle adjustment accuracy caused by the lack of precise transmission components when the printing equipment relies on the servo drive in the movable seat to directly drive the workpiece to rotate. In addition, the lack of a load-resistant reverse rotation structure can easily cause the workpiece angle to deviate, making it difficult to meet the angle control requirements of high-precision printing.

[0012] 2. The clamping plate is moved by the drive mechanism, so that the clamping plate clamps and limits the workpiece, and stably restricts the workpiece within the workstation seat, preventing the workpiece from shifting during the printing process. This ensures the accuracy of the printing position of the pattern on the workpiece surface. It solves the technical problem that the clamping and limiting method of the printing equipment is not optimized for the printing scenario, which easily leads to the workpiece shifting during the printing process, and thus causes the printing position deviation of the pattern on the workpiece surface, making it difficult to ensure the accuracy of the printing position.

[0019] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0020] See Figure 1 and Figure 5 As shown, a printing device for multi-angle printing of workpieces includes a printing machine body 1, on which a mounting groove 11 is provided; a mounting plate 2 is rotatably mounted on the side of the printing machine body 1 near the mounting groove 11; a workstation seat 21 is detachably mounted on the mounting plate 2; a clamping plate 22 is mounted on the workstation seat 21; an adjustment assembly for driving the mounting plate 2 to rotate is provided between the printing machine body 1 and the mounting plate 2; a driving mechanism for driving the clamping plate 22 to achieve displacement is provided between the workstation seat 21 and the clamping plate 22; the adjustment assembly includes a speed reducer 23 and a first power member 24; the speed reducer 23 is fixedly mounted on the printing machine body 1, and the output end of the speed reducer 23 is fixedly connected to the working end of the mounting plate 2; the first power member 24 is fixedly connected to the input end of the speed reducer 23, and the first power member 24 is used to provide power for the rotation of the mounting plate 2.

[0021] Specifically, the reduction component 23 is preferably a worm gear reducer. The first power component 24 is preferably a servo motor.

[0022] When the printing equipment is put into use, first assemble the workstation 21 with the mounting plate 2, and then place the workpiece inside the workstation 21. At this time, the drive mechanism drives the clamping plate 22 to move, so that the clamping plate 22 clamps and limits the workpiece, stably confining the workpiece within the workstation 21, preventing the workpiece from shifting during the printing process, and ensuring the accuracy of the printing position of the pattern on the workpiece surface. Then, start the printing equipment to perform the printing process on the workpiece.

[0023] When the workpiece printing angle needs to be adjusted, the first power component 24 is activated. The output end of the first power component 24 drives the input end of the reducer 23 to rotate, which in turn drives the mounting plate 2 to rotate through the output end of the reducer 23. The mounting plate 2 synchronously drives the station seat 21 and the workpiece within the station seat 21 to rotate, thereby adjusting the workpiece printing angle. The reducer 23 is preferably a worm gear reducer, which provides a self-locking function, effectively preventing reverse rotation of the load. It also precisely reduces the output speed of the first power component 24, improving the control accuracy of angle adjustment and keeping the angle adjustment error within the range required for high-precision printing, thus avoiding print quality issues caused by insufficient printing angle adjustment accuracy.

[0024] In addition, the workpiece clamping and printing angle adjustment process does not require complicated manual intervention, and the workpiece fixing and angle adjustment operations can be completed quickly, which is suitable for batch printing production scenarios and effectively improves the overall printing production efficiency of the equipment.

[0025] See Figures 2-4 As shown, the drive mechanism includes a connecting pad 25 and a second power component 26; the connecting pad 25 is fixedly connected to the inner side of the clamping plate 22; the second power component 26 is detachably fixedly connected to the workstation 21; the drive mechanism also includes a first guide assembly, a transmission assembly, and a second guide assembly; the first guide assembly is disposed between the workstation 21 and the clamping plate 22, and the first guide assembly is used to assist the clamping plate 22 in linear movement; the transmission assembly is disposed between the first guide assembly and the second power component 26, and the transmission assembly is used to transmit the power of the second power component 26 to the first guide assembly; the second guide assembly is disposed between the workstation 21 and the transmission assembly, and the second guide assembly is used to assist the transmission assembly in performing motion actions along a preset trajectory.

[0026] Specifically, the connecting pad 25 is preferably a deformable rubber pad. The second power component 26 is preferably a cylinder.

[0027] After the workpiece is placed inside the workstation seat 21, the second power unit 26 is activated. The power output by the second power unit 26 is transmitted to the first guide component through the transmission component. The first guide component and the second guide component work together to drive the clamping plate 22 to perform displacement action, so that each clamping plate 22 moves closer to each other synchronously along the preset trajectory. During the displacement of the clamping plate 22, each clamping plate 22 synchronously drives the connecting pad 25 to move towards the workpiece.

[0028] During the displacement of the clamping plates 22, each clamping plate 22 synchronously drives the connecting pads 25 to move towards the workpiece, thereby forming a squeezing clamp on the workpiece through the connecting pads 25. Preferably, the connecting pads 25 are deformable rubber pads, allowing them to adaptively deform according to the shape of the workpiece. This increases the contact area with the workpiece, preventing the workpiece from loosening within the workstation seat 21 by enhancing clamping friction, and also adapts to the clamping requirements of workpieces with different shapes. Simultaneously, the deformable characteristic avoids damage to the workpiece surface or structure caused by rigid clamping, ensuring the workpiece remains intact during clamping.

[0029] With the cooperation of clamping plate 22 and connecting pad 25, the workpiece can be stably fixed in the workstation seat 21, effectively preventing the workpiece from shifting during subsequent printing processes or angle adjustment. This provides a stable foundation for printing accuracy control and angle adjustment accuracy assurance, reduces printing deviations caused by unstable workpiece clamping, and improves workpiece printing quality.

[0030] See Figures 2-4 As shown, the first guide assembly includes a slider 27 and a groove 28; the slider 27 is fixedly connected to the lower side of the clamping plate 22; the groove 28 is formed on the side of the workstation 21 near the slider 27, and the groove 28 slides with the slider 27; the transmission assembly includes a first connecting rod 29, a second connecting rod 210, a universal joint 211, and a connecting plate 212; the first connecting rod 29 is disposed in the groove 28, and one end of the first connecting rod 29 is fixedly connected to the slider 27; the second connecting rod 210 is disposed at the end of the first connecting rod 29 away from the slider 27, and both ends of the second connecting rod 210 are respectively connected to the working end of the universal joint 211. The first connecting rod 29 is fixedly connected to the universal joint 211 at one end of the second connecting rod 210. The connecting plate 212 is located at the end of the second connecting rod 210 away from the first connecting rod 29, and the connecting plate 212 is fixedly connected to the working end of the universal joint 211 at the end of the second connecting rod 210 away from the first connecting rod 29. The second guide assembly includes a guide plate 213 and a guide rod 214. The guide plate 213 is fixedly connected to the connecting plate 212, and a through groove is provided in the middle of the guide plate 213. The guide rod 214 is slidably engaged with the through groove of the guide plate 213, and the guide rod 214 is detachably fixedly connected to the workstation 21.

[0031] Specifically, slider 27 and groove 28 form a sliding guide pair. Guide plate 213 and guide rod 214 form a sliding guide pair.

[0032] When the second power component 26 is activated, its output end moves downward along the axial direction, thereby causing the connecting plate 212 to move downward synchronously. During this process, the connecting plate 212 drives the guide plate 213 to slide along the guide rod 214. The guide plate 213 and the guide rod 214 together form a sliding guide pair, which can strictly limit the radial rotational freedom of the connecting plate 212, ensuring that the connecting plate 212 moves stably along the preset axial direction and avoiding rotational deviation during the displacement process.

[0033] When the connecting plate 212 moves downward steadily, it simultaneously pulls the second connecting rod 210 downward. Since the second connecting rod 210 has universal joints 211 installed at both ends, the universal joints 211 can adaptively rotate according to the direction of the pulling force applied by the connecting plate 212, allowing the second connecting rod 210 to flexibly adapt to the direction of force transmission, thereby reliably pulling the first connecting rod 29. After being subjected to force, the first connecting rod 29 drives the slider 27 to slide along the slide groove 28. The slider 27 and the slide groove 28 form a sliding guide pair, which can effectively suppress the swaying and offset of the slider 27 during displacement, ensuring that the slider 27 moves stably along the slide groove 28.

[0034] During the stable movement of the slider 27, it synchronously drives each clamping plate 22 to move closer to each other along a preset trajectory, so that the clamping plate 22 can form a stable clamping limit on the workpiece in the workstation seat 21, ensuring the accuracy and reliability of the clamping action.

[0035] Working principle: When the printing equipment is put into use, first assemble the workstation 21 and the mounting plate 2, then place the workpiece inside the workstation 21, start the second power component 26, and cause each clamping plate 22 to move closer to each other along the preset trajectory to clamp and limit the workpiece in the workstation 21. At this time, the printing equipment can be started to perform the printing process on the workpiece. When it is necessary to adjust the printing angle of the workpiece, start the first power component 24. The first power component 24 drives the mounting plate 2 to rotate through the speed reducer 23, thereby realizing the adjustment of the printing angle of the workpiece.

[0036] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
