Description

Technical Field

[0001] This utility model relates to the field of pad printing adhesive removal technology, and in particular to an adhesive removal structure for pad printing. Background Technology

[0002] Pad printing is a printing technology that transfers ink from a steel plate to an object using a pad. During pad printing, ink or dirt often remains on the pad after each print. If not cleaned promptly, these residues can affect the accuracy of subsequent printing, leading to blurred patterns, uneven colors, and reduced product quality. Therefore, effective ink removal and cleaning techniques are needed to ensure the cleanliness of the pad printing head. However, current pad printing ink removal technologies have the following shortcomings: Firstly, current methods rely mainly on manual cleaning, which is time-consuming and labor-intensive. Uneven wiping can also result in residue, requiring multiple cleanings, making it unsuitable for the continuous production demands of pad printing machines. Secondly, existing technologies using cleaning belts require machine downtime for belt replacement, wasting significant time. Finally, current pad printing ink removal and related equipment setups occupy considerable space, making them inconvenient for use in space-constrained production environments. Utility Model Content

[0003] This invention proposes a glue removal structure for pad printing to solve the problems mentioned in the background art, such as the inability to clean continuously, poor cleaning effect, and large equipment space occupation.

[0004] The technical solution of this utility model is implemented as follows:

[0005] A glue removal structure for pad printing includes:

[0006] Fixed base;

[0007] The first lead screw is mounted on a fixed seat, which is mounted on one side of the connecting block.

[0008] The pad printing head is installed in the middle of the connecting block, and its lower end extends downward;

[0009] The rubber plate is positioned below the connecting block and can move horizontally and vertically.

[0010] The tape, placed on the tape tray, can be laid flat and conveyed horizontally on the tape tray;

[0011] During adhesive removal, the adhesive plate can move the tape to below the printing head, and use the tape to clean the residue on the printing head.

[0012] By adopting the above technical solution, the residue on the pad printing head can be quickly removed with the help of tape. The tape can move in both horizontal and vertical directions, which can meet the cleaning needs under different working conditions. The tape is laid flat on the tape and transported horizontally, which can achieve continuous cleaning.

[0013] Preferably, the support and heating device includes a heating plate, a pad, and a frame, which are sequentially installed below the adhesive plate.

[0014] By adopting the above technical solution, the heating plate heats the adhesive plate to maintain a certain temperature, which can enhance the cleaning effect, while the pad can provide cushioning to prevent excessive stress, and the slatted frame can distribute the overall weight and maintain stability during the cleaning process.

[0015] Preferably, the tape take-up and take-down device specifically includes a tape placing roller and a tape taking-up roller, which are respectively installed at both ends of the mechanism.

[0016] By adopting the above technical solutions, the rubber roller can stabilize the tape roll and prevent the tape from rolling and deviating during use, while the rubber take-up roller can recycle the waste part in real time.

[0017] Preferably, the tape guiding device specifically comprises an auxiliary roller on the slide rail and a tape-passing groove below the slide rail.

[0018] By adopting the above technical solutions, the auxiliary roller can guide and tension the conveyor belt, ensuring that the rubber material remains stable during the process of the conveyor belt being transferred from the rubber placement roller to the rubber take-up roller; the rubber groove provides path constraint for the conveyor belt, avoiding friction and entanglement between the conveyor belt and other parts of the slide rail.

[0019] Preferably, the first slider is mounted on the first lead screw, and its shape is close to that of the connecting block and fits the connecting block concave and convex.

[0020] By adopting the above technical solutions, the rubber roller can stabilize the tape roll and prevent the tape from rolling and deviating during use, while the rubber take-up roller can recycle the waste part in real time.

[0021] Preferably, a second slider is fixed on the slide rail, and a second lead screw is installed on the second slider. The second slider is connected to the first slider through the second lead screw.

[0022] By adopting the above technical solution, not only is there a sliding cooperation between the slide rail and the first slider, but also a second lead screw connecting the slide rail and the first slider, which can ensure the stability of the structure while ensuring smooth sliding.

[0023] Preferably, the first slider moves horizontally along the first lead screw, and the second slider drives the slide rail to move vertically along the second lead screw.

[0024] By adopting the above technical solution, the horizontal and vertical movements enable flexible displacement of the printing plate, adapting to printing heads of different heights and positions. Simultaneously, this design not only reduces motion interference but also indirectly extends the service life of key components such as the lead screw and the first slider.

[0025] Preferably, a roller is installed at the concave-convex mating part of the first slider and the connecting block.

[0026] By adopting the above technical solution, the installation of rollers makes the force exerted by the slider on the connecting block more balanced, and the movement more stable and smooth.

[0027] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0028] The use of rollers, sliders, and connecting blocks solves the problem of easy jamming in traditional structures. The horizontal movement of the first slider along the first lead screw and the vertical movement of the slide rail along the second lead screw, unlike the traditional single-dimensional adjustment, enable flexible positioning of the adhesive removal mechanism. The mechanism is equipped with auxiliary rollers and adhesive grooves to regulate the tape transmission path and solve the problem of tape deviation. Unlike the single function of traditional adhesive placement plates, a composite support design of slatted frame and pads is adopted, combined with a heating plate under the adhesive placement plate, which balances cleaning efficiency and improves support performance.

[0037] 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.

[0038] See Figure 1-5 A glue removal structure for pad printing, comprising:

[0039] Fixture 1;

[0040] The first lead screw 101 is mounted on the fixed seat 1, and the fixed seat 1 is mounted on one side of the connecting block 2;

[0041] The pad printing head 201 is installed in the middle of the connecting block 2, and its lower end extends downward;

[0042] The adhesive plate 6 is positioned below the connecting block 2 and can move in both horizontal and vertical directions;

[0043] The tape is placed on the tape tray 6 and can be laid flat and conveyed horizontally on the tape tray 6.

[0044] When removing adhesive, the adhesive plate 6 can move the tape to below the pad printing head 201 and use the tape to clean the residue on the pad printing head 201.

[0045] Specifically, the support and heating device includes a heating plate 7, a pad 8, and a frame 9, which are sequentially installed below the adhesive placement plate 6. The heating plate 7 has the same shape as the adhesive placement plate 6 to ensure that the adhesive placement plate 6 can be heated evenly. The appropriate temperature can soften the residual substances on the pad printing head 201, resulting in better tape cleaning effect. The crossbars of the frame 9 are composed of multiple small rods 901, which can ensure support strength while reducing the overall weight. The frame structure formed by the vertical and horizontal bars, together with the pad 8, the adhesive placement plate 6, and the slide rail 5, enhances the overall structure's resistance to deformation.

[0046] Specifically, the glue plate 6 is a hexagon with narrow ends and a wide middle. Compared with traditional rectangular shapes, the narrow ends can transmit and disperse stress when the wide middle area bears the main pressure, reducing the deformation of the glue plate 6 caused by local stress. Together with the pad 8 and the frame 9 below, it can further enhance the stability of the structure.

[0047] Specifically, the tape take-up and take-up device includes a tape placement roller and a tape take-up roller, which are respectively installed at both ends of the mechanism. The tape take-up roller 304 is connected to a motor 305, which is mounted on the first slider 3 via a motor frame 306. The tape starts from the tape placement roller 303 and is collected at the tape take-up roller 304. The entire device is linked by a second lead screw 4. When the mechanism rises, the motor 305 starts, driving the tape take-up roller 304 to roll up the tape. When the mechanism descends, the motor 305 locks, and under the action of the second lead screw 4, the slide rail 5 moves relative to the tape placement roller 303, causing the tape placement roller 303 to release new tape, thus realizing automatic tape replacement.

[0048] Specifically, fixing the motor 305 to the first slider 3 via the motor frame 306 can make full use of the space around the first slider 3, making the overall structure more compact, avoiding the motor 305 occupying extra space, which is conducive to the miniaturization design of the equipment, and also reduces the possibility of the motor 305 interfering with other components.

[0049] Specifically, the tape guiding device comprises an auxiliary roller 502 on the slide rail 5 and a glue-feeding groove 503 below the slide rail 5. The auxiliary roller 502 can rotate and contact the tape surface to provide longitudinal support and lateral restraint for the tape, preventing the tape from deviating during conveying and ensuring that the tape moves along the preset path. The glue-feeding groove 503 below the auxiliary roller 502 is a narrow groove that matches the width of the tape, which can constrain the tape and ensure that the tape is laid out flat.

[0050] Specifically, a second slider 401 is fixed on the slide rail 5, and a second lead screw 4 is mounted on the second slider 401. The second slider 401 is connected to the first slider 3 via the second lead screw 4. The first slider 3 is connected to the second slider 401 via the second lead screw 4 and can slide along the slide rail 5, forming a linkage structure. This reduces shaking or offset during adjustment, and maintains stability, especially during cleaning.

[0051] Specifically, the first slider 3 moves horizontally along the first lead screw 101, and the second slider 401 drives the slide rail 5 to move vertically along the second lead screw 4. The first and second lead screws are driven and controlled by separate motors, enabling different working requirements in the horizontal and vertical directions. The rotation of the first lead screw 101 is converted into the horizontal movement of the first slider 3 along the first lead screw 101, moving the mechanism to the working position or standby position. The rotation of the second lead screw 4 is converted into the vertical movement of the slide rail 5 along the second lead screw 4, responsible for lifting and lowering the adhesive plate 6, and completing the replacement of the adhesive tape with the cooperation of the tape take-up and tape guide device.

[0052] Specifically, rollers are installed at the convex-concave mating point between the first slider 3 and the connecting block 2. A first movable wheel 301 and a second movable wheel 302 are correspondingly installed at the upper and lower ends of the convex-concave mating point between the first slider 3 and the connecting block 2. The first movable wheel 301 is installed at the upper convex-concave mating point between the first slider 3 and the connecting block 2 and fits against the upper surface of the connecting block 2. The second movable wheel 302 is installed at the lower convex-concave mating point between the first slider 3 and the connecting block 2 and fits against the lower surface of the connecting block 2. The corresponding installation of the first movable wheel 301 and the second movable wheel 302 enhances the fit between the first slider 3 and the connecting block 2, prevents wobbling, and makes the movement of the first slider 3 on the connecting block 2 more stable.

[0053] During operation, the entire mechanism moves along the direction of the first lead screw 101 to the pad printing head 201. The heating plate 7 heats the adhesive plate 6, the second lead screw 4 is activated, and the drive rail 5 lifts the mechanism. Then, the pad printing head 201 completes one printing action on the adhesive plate 6 to achieve cleaning. If any residue is found, multiple up-and-down cleaning operations can be performed. After the work is completed, the mechanism returns to its initial position. The second lead screw 4 and the first lead screw 101 are activated to return the mechanism to its initial position and complete the tape replacement. At the same time, the entire mechanism is lifted into standby mode to avoid affecting the normal pad printing process.

[0054] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, any modifications, equivalent substitutions, improvements, etc. made in accordance with the spirit and principles of this application should be included within the scope of protection of this utility model.
