Detailed Implementation

[0028] 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.

[0029] Please see Figure 1-7A sign printing device includes a base 101, on which a lifting and adjusting column 102 is fixedly mounted. An upper mounting plate 103 and a lower mounting plate 104 are fixedly mounted at the upper and lower ends of the lifting and adjusting column 102, respectively. A lifting guide rail 105 is fixed between the upper mounting plate 103 and the lower mounting plate 104. A lifting slider 106 is slidably mounted on the lifting guide rail 105. A lifting and adjusting cylinder 107 is fixedly mounted on the upper mounting plate 103. A connecting rod 109 is fixedly connected between the working shaft of the lifting and adjusting cylinder and the upper mounting plate 103 and the lifting slider 106.

[0030] A lifting mounting plate 110 is fixedly mounted on the lifting slider 106. A steering adjustment module 111 is fixedly mounted on the lifting mounting plate 110. A double-headed gripper cylinder 112 is fixedly mounted on the working shaft of the steering adjustment module 111. A clamping mounting plate 114 is fixedly mounted on the gripper 113 of the double-headed gripper cylinder 112. A telescopic adjustment component 115 is mounted on the clamping mounting plate 114. An auxiliary clamping component 116 is mounted on the telescopic adjustment component 115.

[0031] The auxiliary clamping assembly 116 includes an auxiliary clamping member 117 mounted on the telescopic adjustment assembly 115. The auxiliary clamping member 117 is provided with a first clamping rod 118 and a second clamping rod 119 that clamp and cooperate with each other.

[0032] This utility model of a stand-up printing device integrates a lifting adjustment cylinder, a steering adjustment module 111, a double-headed gripper cylinder 112, and an auxiliary clamping component 116, which realizes fully automatic and precise flipping and positioning of acrylic stand-up during double-sided printing. This significantly improves printing efficiency, reduces positioning deviation caused by manual flipping, and its adjustable design can adapt to the stable clamping of stand-up with different sizes, ensuring the alignment accuracy and quality consistency of double-sided pattern printing.

[0033] The lifting cylinder drives the slider in conjunction with the guide rail to achieve precise height adjustment of the stand. The steering module directly drives the double-headed gripper cylinder 112 to complete 180° automatic rotation, replacing inefficient manual rotation. The telescopic adjustment component 115 and the auxiliary clamping component 117 (including the first and second clamping rods 119) ensure that the stand is always firmly clamped and its position is controllable throughout the entire process of lifting, rotating and printing, which fundamentally solves the efficiency bottleneck and positioning inaccuracy problem caused by manual operation.

[0034] The mechanized flipping and positioning process completely eliminates the instability of manual operation. The clamping components provide a flexible and stable fixation for the acrylic stand, preventing scratches or loosening and ensuring that the printed patterns on both sides are strictly aligned (precise registration), which greatly improves the product qualification rate.

[0035] The lifting mechanism adapts to different heights of standees; the gripper 113 cylinder, together with the adjustable telescopic component and auxiliary clamping component 117, can be compatible with acrylic standees of various sizes, enabling the production line to quickly switch products;

[0036] Full-process automation reduces the need for manual intervention, lowers labor intensity and labor costs, while high-speed and stable mechanical operation significantly increases output per unit time.

[0037] In this embodiment of the utility model, the telescopic adjustment assembly 115 includes a first guide shaft 120 and a second guide shaft 121 fixed on the auxiliary clamping member 117 and a screw member 122 rotatably disposed on the auxiliary clamping member 117. The first guide shaft 120 and the second guide shaft 121 are slidably engaged on the clamping mounting plate 114. The end of the screw member 122 extends out of the clamping mounting plate 114 and is screwed with an adjustment knob member 123.

[0038] This utility model of a stand-up printing device achieves linear precision guidance of the auxiliary clamping member 117 through the sliding engagement of the first guide shaft 120 and the second guide shaft 121 on the clamping mounting plate 114. Combined with the threaded transmission mechanism of the screw member 122 and the adjusting knob member 123, the operator can apply high-precision displacement to the auxiliary clamping member 117 by rotating the adjusting knob member 123, thereby adjusting the distance between the first clamping rod 118 and the second clamping rod 119. It can be compatible with acrylic stand-ups of various sizes, and dynamically optimizes the lateral clamping force on irregularly shaped acrylic stand-ups. This ensures zero shaking of the stand-up during printing and avoids deformation or surface indentation of thin-walled stand-ups caused by uneven clamping force. At the same time, this purely mechanical adjustment structure does not require additional pneumatic / electric units, significantly reducing maintenance costs and extending service life.

[0039] In this embodiment of the utility model, a steering adjustment shaft 124 is fixedly provided on the auxiliary clamping member 117, the first clamping rod 118 is rotatably disposed on the steering adjustment shaft 124, an elastic abutment member 125 is fixedly provided on the auxiliary clamping member 117 to elastically abut against the rear end of the first clamping rod 118, and a limiting block 126 is fixedly provided on the auxiliary clamping member 117 to abut against and limit the lower end face of the first clamping rod 118.

[0040] The auxiliary clamping structure of this utility model's stand-up printing device achieves the active rotational freedom of the first clamping rod 118 through the steering adjustment shaft 124. In conjunction with the elastic abutment 125, a controllable pre-pressure is applied to the rear end of the clamping rod, allowing the front end of the clamping rod to dynamically conform to the curved contour of the acrylic stand-up. At the same time, the limiting block 126 precisely constrains the downward swing angle of the clamping rod. Under the premise of ensuring the three-dimensional clamping stability of irregularly shaped stand-up, the elastic deformation absorbs the assembly tolerance and workpiece deformation stress, completely eliminating the local stress concentration phenomenon caused by rigid clamping. This significantly reduces the risk of clamping deformation of thin-walled or hollow stand-up and improves the anti-displacement reliability during the printing process of curved stand-up.

[0041] In this embodiment of the utility model, a wrench component 127 is fixedly provided at the rear end of the upper end face of the first clamping rod 118.

[0042] During use, the front end of the first clamping rod 118 can be lifted upward by the wrench 127, thereby increasing the clamping space between the first clamping rod 118 and the second clamping rod 119, which facilitates the placement of the stand-up product and makes the clamping and feeding process more convenient.

[0043] In this embodiment of the present invention, the second clamping rod 119 is provided with an air duct 128, and an air outlet assembly 129 is provided on the side of the second clamping rod 119 opposite to the first clamping rod 118. The air outlet assembly 129 includes a left air outlet 130 and a right air outlet 131 respectively located close to both sides. An impeller 132 is installed inside the auxiliary clamping member 117.

[0044] This utility model of a stand-up printing device integrates a dual-flow system (left / right air outlet 131 component 129) inside the clamping rod, which, together with the directional airflow generated by the impeller component 132, forms a symmetrically covered turbulent field on both sides of the acrylic stand-up's clamped surface, achieving a dual-effect synergy. On the one hand, forced convection accelerates ink drying, preventing undried ink from sticking to the clamping surface and causing pattern contamination during flipping. On the other hand, through airflow temperature exchange, it suppresses local thermal deformation of the stand-up caused by printing heat, ensuring interlayer alignment during high-precision overprinting. At the same time, the built-in air duct 128 eliminates the need for external dust removal equipment, completing the dust removal operation of the product during flipping, ensuring the product's cleanliness meets customer requirements.

[0045] In this embodiment of the utility model, the first clamping rod 118 and the second clamping rod 119 are provided with silicone reinforcing rib rings 133;

[0046] This utility model of a stand-up printing device constructs a raised elastic support structure on the contact surface of the clamping rod; the elastic deformation of the ribs effectively disperses local pressure, preventing indentations or micro-cracks from forming on thin-walled stand-ups; in addition, the silicone material reduces scratch damage to the ink printing surface, and the airflow channels between the ribs maintain drying efficiency, thereby improving the yield rate of curved / high-gloss stand-ups.

[0047] In this embodiment of the utility model, a limit switch 134 is installed on the upper mounting plate 103, and the limit switch 134 is in contact with the lifting mounting plate 110.

[0048] This utility model of a stand-up printing device forms a dual safety protection mechanism through mechanical contact with the lifting mounting plate 110; at the upper end of the lifting adjustment cylinder stroke, the limit switch 134 is triggered to cut off the cylinder air supply in real time and lock the slider position, effectively preventing equipment collision accidents caused by pneumatic system overshoot; at the same time, the limit switch 134 structure can also provide a physical calibration benchmark for the lifting stroke, eliminate cumulative positioning errors, ensure the consistency of the printing height of each batch of stand-up printing devices, and significantly reduce the frequency of equipment maintenance and unexpected downtime losses.

[0049] In this embodiment of the present invention, the steering adjustment module 111 includes a rotary cylinder component 135;

[0050] The steering adjustment module 111 of the stand printing device of this utility model adopts a rotary cylinder 135 as the core drive unit. Through its high responsiveness and built-in hydraulic damper, it realizes high-speed and stable steering of the stand. Combined with high-precision repeatable positioning, it ensures accurate registration of double-sided printed patterns. Its IP67 protection level effectively resists ink pollution and dust corrosion in the printing workshop, significantly improving the reliability and economy of the production line.

[0051] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
