Description

Technical Field

[0001] This utility model relates to the field of bowl lid printing technology, specifically a bowl lid printing device for improving printing effect. Background Technology

[0002] With rising consumption levels and evolving aesthetic demands, plain-colored bowl lids can no longer satisfy consumers' diverse expectations for product appearance, nor can they help brands gain a differentiated competitive advantage. Printing bowl lids allows brands to display logos, distinctive patterns, and promotional slogans, enhancing brand recognition and enabling consumers to quickly identify and remember the brand among numerous products (e.g., exclusive bowl lid prints for catering brands can strengthen brand recall and loyalty). Furthermore, personalized print designs attract consumer attention, improving the product's competitiveness in the market.

[0003] Existing devices lack sufficient positioning accuracy for the bowl lids and often use mechanical clamping to fix them. This not only makes it difficult to ensure the flatness of the bowl lids during the printing process, but also easily causes squeezing damage to the surface of the bowl lids due to improper control of clamping force. This damage problem is particularly prominent for bowl lids made of thinner or more easily deformable materials.

[0004] Therefore, this utility model provides a bowl lid printing device to improve the printing effect and solve the above problems. Utility Model Content

[0005] This invention provides a bowl lid printing device to improve printing effect, aiming to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A bowl lid printing device for improving printing effect includes a printing box and a printing mechanism. A printing material pool is provided inside the printing box, and the printing mechanism is telescopically installed on the top of the printing material pool.

[0007] A support plate is fixedly installed on one side of the top surface of the printing ink pool, and a placement groove is opened on the top of the support plate.

[0008] The printing mechanism includes a fixed plate, a top plate fixedly installed on the top of the fixed plate, a cylinder fixedly installed on the top of the top plate, a sleeve fixedly installed at the bottom of the cylinder, a pneumatic tube telescopically connected to the bottom of the sleeve, an suction head fixedly installed at the bottom of the pneumatic tube, a slide rail fixedly installed on one side of the top of the printing ink tank, spring rods fixedly installed on both sides of the slide rail surface, a lifting plate slidably installed at the intersection of the spring rod surfaces, and a slot is opened on the surface of the lifting plate.

[0009] The printing mechanism is telescopically mounted on top of the printing ink tank. Equipped with a telescopic assembly consisting of a cylinder, sleeve, and pneumatic hose, it allows for flexible adjustment of the suction head's height. This facilitates precise control of the printing distance based on the actual thickness of the bowl lid, effectively preventing blurry printing or pattern misalignment caused by improper distance. The suction head, linked to the cylinder via the pneumatic hose, reliably suctions the bowl lid to ensure its flatness during printing. The telescopic movement also automates the printing process, reducing manual labor intensity and ensuring more uniform adhesion and clearer, more complete patterns through precise mechanical control. This improves the overall quality and production efficiency of bowl lid printing, meeting the needs of mass production.

[0010] As a preferred technical solution of this application, a guide rail is fixedly installed on the surface of the fixed plate, a servo motor is fixedly installed at the bottom of the guide rail, a lead screw is fixedly connected to the top of the servo motor, a slider is threadedly connected to the surface of the lead screw, a connecting rod is fixedly installed on one side of the slider, and a gripper is fixedly connected to one side of the connecting rod. The servo motor can accurately output speed and torque. The lead screw and slider connected to its top form a threaded transmission structure, and the slider is fixedly connected to the gripper through the connecting rod, so that the gripper can move synchronously and accurately with the slider.

[0011] As a preferred technical solution of this application, the gripper is fixedly attached to the surface of the pneumatic tube. The servo motor drives the lead screw to rotate, causing the slider to slide on the threaded surface of the lead screw. Simultaneously, the pneumatic tube is driven to extend and retract at the bottom of the sleeve, allowing the suction head to extend into the printing ink pool. This achieves automated and precise control of the extension and retraction of the pneumatic tube. The servo motor can precisely control the rotation angle of the lead screw according to the actual printing needs, thereby precisely adjusting the extension and retraction of the pneumatic tube. This ensures that the suction head can accurately extend to the designated position inside the printing ink pool. This avoids the problem of insufficient extension of the suction head leading to insufficient ink pick-up and affecting the printing effect, and also prevents excessive extension from causing the suction head to pick up too much ink and resulting in pattern smudging. This improves the controllability and stability of the ink pick-up process of the suction head.

[0012] As a preferred technical solution of this application, a bowl lid is placed on the surface of the placement groove, and the suction head is connected to the cylinder through a pneumatic tube, so that the bowl lid is adsorbed on the bottom of the suction head. The bowl lid is snapped onto the surface of the placement groove, which can play a role in pre-positioning and fixing the bowl lid. At the same time, the suction head is connected to the cylinder through a pneumatic tube, and the pressure difference generated by the cylinder is used to achieve adsorption and fixation of the bowl lid. This not only ensures that the bowl lid fits tightly to the surface of the bowl lid, ensuring the flatness of the bowl lid in the adsorption state, and avoiding the bowl lid from shifting or wrinkling in the subsequent printing process due to insecure fixation, but also reduces the squeezing damage to the surface of the bowl lid that may be caused by traditional mechanical clamping methods. While ensuring the integrity of the bowl lid, it provides a stable workpiece foundation for subsequent accurate printing.

[0013] As a preferred technical solution of this application, the bottom of the adsorption head is vertically aligned with the top of the printing ink pool and with the slot. The surface of the slot is engaged with the bowl cover. The adsorption head is vertically raised and lowered on the surface of the screw rod in sync with the slider via the gripper, and simultaneously drives the lifting plate to raise and lower, so that the bottom of the bowl cover extends into the printing ink pool. This allows for precise control of the lifting height of the adsorption head, which can flexibly adjust the descent depth of the adsorption head according to the remaining amount of printing ink in the printing ink pool, ensuring that the amount of printing ink picked up each time is consistent, ensuring uniform printing pressure, and effectively avoiding problems such as blurred, incomplete, or over-pressed printing patterns caused by height deviation, thereby further improving the accuracy and consistency of printing.

[0014] As a preferred technical solution of this application, the adsorption heads are evenly distributed on the top of the printing ink pool. By setting multiple adsorption heads, printing ink dipping and bowl lid printing operations can be carried out simultaneously, which improves the production efficiency of bowl lid printing and meets the needs of mass production.

[0015] As a preferred technical solution of this application, the gripper is semi-circular in shape, matching the diameter of the air pressure tube, and synchronously drives the air pressure tube to rise and fall at the top of the printing ink tank, making contact with the printing ink inside the printing ink tank. This effectively allows the gripper to fit tightly against the surface of the air pressure tube, ensuring the gripper's firm hold on the air pressure tube and preventing the air pressure tube from loosening or falling off during the lifting and lowering process, thus ensuring the stability and safety of the transmission.

[0016] The adsorption head is linked to the cylinder through an air pressure tube, and uses the air pressure difference to reliably adsorb the bowl lid, which not only ensures the flatness during printing, but also avoids the damage to the bowl lid caused by traditional mechanical clamping; multiple evenly distributed adsorption heads can work simultaneously, which significantly improves the efficiency of mass production; the automated extension and adsorption action reduces manual intervention and labor intensity, while the stable transmission of the mechanical structure ensures the consistency of printing quality.

[0017] The slider and connecting rod drive the semi-circular gripper and air pressure tube to extend and retract, allowing the adsorption head to precisely extend to the designated position in the printing ink pool. This avoids insufficient adsorption affecting the printing effect, while also preventing excessive adsorption from causing the pattern to bleed. At the same time, the adsorption head is vertically aligned with the printing ink pool and can be vertically raised and lowered for adjustment. This allows for flexible adjustment of the adsorption depth based on the remaining amount in the ink pool, ensuring consistent adsorption each time. This effectively solves problems such as blurred or incomplete printing caused by distance deviation or positional offset, improving the integrity and uniformity of the printed pattern.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides a bowl lid printing device to improve the printing effect, such as... Figure 1-5 As shown, it includes a printing box 100 and a printing mechanism 200. A printing material pool 101 is provided inside the printing box 100, and the printing mechanism 200 is telescopically installed on the top of the printing material pool 101.

[0022] A support plate 102 is fixedly installed on one side of the top surface of the printing ink pool 101, and a placement groove 103 is opened on the top of the support plate 102.

[0023] The printing mechanism 200 includes a fixed plate 201, a top plate 202 fixedly installed on the top of the fixed plate 201, a cylinder 203 fixedly installed on the top of the top plate 202, a sleeve 212 fixedly installed at the bottom of the cylinder 203, a pneumatic tube 204 telescopically connected to the bottom of the sleeve 212, an adsorption head 205 fixedly installed at the bottom of the pneumatic tube 204, a slide rail 213 fixedly installed on one side of the top of the printing ink tank 101, spring rods 214 fixedly installed on both sides of the surface of the slide rail 213, a lifting plate 215 slidably installed at the intersection of the surfaces of the spring rods 214, and a slot 216 is opened on the surface of the lifting plate 215.

[0024] The printing mechanism 200 is telescopically mounted on the top of the printing material tank 101. It is equipped with a telescopic assembly consisting of a cylinder 203, a sleeve 212, and a pneumatic tube 204. This assembly allows for flexible adjustment of the height of the suction head 205, facilitating precise control of the printing distance based on the actual thickness of the bowl lid. This effectively avoids printing blurring or pattern offset caused by improper distance. The suction head 205 is linked to the cylinder 203 via the pneumatic tube 204, ensuring reliable suction of the bowl lid to guarantee its flatness during the printing process. It also enables automated connection of the printing operation through telescopic movement. This not only reduces the labor intensity of manual operation but also, through precise control of the mechanical structure, makes the adhesion of the printed pattern on the bowl lid more uniform and the pattern clearer and more complete, improving the overall quality and production efficiency of bowl lid printing and meeting the production needs of batch bowl lid printing.

[0025] like Figure 3 As shown, a guide rail 206 is fixedly mounted on the surface of the fixed plate 201. A servo motor 207 is fixedly mounted on the bottom of the guide rail 206. A lead screw 208 is fixedly connected to the top of the servo motor 207. A slider 209 is threadedly connected to the surface of the lead screw 208. A connecting rod 210 is fixedly mounted on one side of the surface of the slider 209. A gripper 211 is fixedly connected to one side of the surface of the connecting rod 210. The servo motor 207 can accurately output speed and torque. The lead screw 208 and the slider 209 connected to its top form a threaded transmission structure. The slider 209 is fixedly connected to the gripper 211 through the connecting rod 210, so that the gripper 211 can move synchronously and accurately with the slider 209.

[0026] like Figure 3 As shown, the gripper 211 is fixedly engaged with the surface of the air pressure tube 204. The servo motor 207 drives the lead screw 208 to rotate, causing the slider 209 to slide threadedly on the surface of the lead screw 208. Simultaneously, the air pressure tube 204 is driven to extend and retract at the bottom of the sleeve 212, allowing the adsorption head 205 to extend into the printing ink pool 101. This achieves automated and precise control of the extension and retraction of the air pressure tube 204. The servo motor 207 can precisely control the rotation angle of the lead screw 208 according to the actual printing requirements, thereby precisely adjusting the extension and retraction of the air pressure tube 204. This ensures that the adsorption head 205 can accurately extend to the designated position inside the printing ink pool 101. This avoids the problem of insufficient extension of the adsorption head 205, which would result in insufficient ink absorption and affect the printing effect. It also prevents excessive extension of the adsorption head 205, which would cause the pattern to smudge due to excessive ink absorption. This improves the controllability and stability of the adsorption head 205's ink absorption process.

[0027] like Figure 3-5As shown, a bowl lid is placed on the surface of the placement groove 103. The suction head 205 is connected to the cylinder 203 via the air pressure pipe 204, so that the bowl lid is adsorbed on the bottom of the suction head 205. The bowl lid is snapped onto the surface of the placement groove 103, which can play a role in pre-positioning and fixing the bowl lid. At the same time, the suction head 205 is connected to the cylinder 203 via the air pressure pipe 204, and the air pressure difference generated by the cylinder 203 is used to achieve the adsorption and fixation of the bowl lid. This not only ensures that the bowl lid fits tightly against the surface of the bowl lid, ensuring the flatness of the bowl lid in the adsorption state, and avoiding the bowl lid from shifting or wrinkling in the subsequent printing process due to insecure fixation, but also reduces the squeezing damage to the surface of the bowl lid that may be caused by traditional mechanical clamping methods. While ensuring the integrity of the bowl lid, it provides a stable workpiece foundation for subsequent accurate printing.

[0028] like Figure 2 and Figure 4 As shown, the bottom of the adsorption head 205 is vertically aligned with the top of the printing ink pool 101 and with the slot 216. The surface of the slot 216 is engaged with the bowl lid. The adsorption head 205 is vertically raised and lowered on the surface of the screw 208 simultaneously with the slider 209 via the gripper 211, and simultaneously drives the lifting plate 215 to rise and fall, so that the bottom of the bowl lid extends into the printing ink pool 101. The lifting height of the adsorption head 205 can be precisely controlled, and the descent depth of the adsorption head 205 can be flexibly adjusted according to the remaining amount of printing ink in the printing ink pool 101, ensuring that the amount of printing ink dipped each time is consistent, ensuring uniform printing pressure, and effectively avoiding problems such as blurred, incomplete or over-pressed printing patterns caused by height deviation, thereby further improving the accuracy and consistency of printing.

[0029] like Figure 1-4 As shown, the adsorption heads 205 are evenly distributed on the top of the printing material pool 101. By setting multiple adsorption heads 205, printing material dipping and bowl lid printing operations can be carried out simultaneously, which improves the production efficiency of bowl lid printing and meets the needs of mass production.

[0030] like Figure 3 As shown, the gripper 211 is semi-circular in shape, matching the diameter of the air pressure tube 204. It simultaneously drives the air pressure tube 204 to rise and fall at the top of the printing ink tank 101, making contact with the printing ink inside the printing ink tank 101. This effectively ensures that the gripper 211 can tightly fit the surface of the air pressure tube 204, ensuring the gripper 211's firm hold on the air pressure tube 204. This prevents the air pressure tube 204 from loosening or falling off during the lifting and lowering process, thus ensuring the stability and safety of the transmission.

[0031] In summary: First, the bowl lid to be printed is snapped into the placement groove 103 at the top of the support plate 102, thus pre-positioning the bowl lid. Then, the bowl lid to be printed is manually snapped into the slot 216 on the lifting plate 215. The slot 216 has a larger diameter at the top and a smaller diameter at the bottom, with the top diameter being smaller than the top diameter of the bowl lid, effectively securing the bowl lid to the surface of the slot 216. The bottom diameter is larger than the bottom diameter of the bowl lid, allowing the bottom of the bowl lid to be exposed at the bottom of the slot 216. The top of 216 is perpendicular to the adsorption head 205. Therefore, when the cylinder 203 is activated, a pressure difference is generated through the air pressure pipe 204, causing the adsorption head 205 to precisely adhere to and adsorb the bowl lid, ensuring that the bowl lid remains flat in the adsorption state, while avoiding damage to the bowl lid caused by traditional mechanical clamping. Next, the servo motor 207 drives the lead screw 208 to rotate. Since the lead screw 208 is threadedly connected to the slider 209, and the slider 209 is fixed to the semi-circular annular gripper 211 through the connecting rod 210, the rotational motion of the lead screw 208 is converted into the vertical motion of the slider 209 along the guide rail 206. The vertical sliding motion causes the air pressure pipe 204 to extend and retract within the sleeve 212, allowing the suction head 205 (adsorbing the bowl lid) to precisely descend to the designated position at the top of the printing ink tank 101 along with the lifting plate 215. Because the suction head 205 is perpendicular to the printing ink tank 101, and the servo motor 207 can precisely control the rotation angle of the lead screw 208, the descent depth of the suction head 205 can be flexibly adjusted. Furthermore, when the suction head 205 presses against the lifting plate 215, the bowl lid exposed at the bottom of the slot 216 is effectively submerged inside the printing ink tank 101, while the bottom of the lifting plate 215... The part remains above the printing ink pool 101, thus ensuring that the suction head 205 fully picks up the appropriate amount of printing ink (avoiding insufficient or excessive picking), and also ensuring that the printing ink inside the printing ink pool 101 does not contaminate the surface of the lifting plate 215; after the ink is picked up, the lifting plate 215 returns to its original position with the spring rod 214, and the servo motor 207 drives the lead screw 208 in the opposite direction, causing the slider 209, the air pressure pipe 204 and the suction head 205 to rise, causing the bowl cover to separate from the printing ink pool 101, so that the bowl cover adsorbed at the bottom of the suction head 205 and the printing ink complete the printing operation.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
