Description

Technical Field

[0001] This utility model relates to the field of printing machine technology, specifically to a dual-station running table printing machine. Background Technology

[0002] A table printing machine, also known as a tabletop printing machine, screen printing machine, or moving table printing machine, is a new type of tabletop printing equipment that uses automatic movement to replace the existing manual screen printing operator to print different sizes, patterns, and processes on a traditional manual screen printing table.

[0003] Traditional tabletop printing machines typically employ a single-station design, resulting in low printing efficiency. While multi-station equipment can increase production capacity, it suffers from the following drawbacks:

[0004] 1. Poor synchronization: Each workstation needs to be configured with an independent lifting and traversing mechanism, which results in inconsistent lifting positions between the two workstations, making it impossible to achieve parallel synchronous operation between the two workstations;

[0005] 2. High cost: Multiple drive systems increase manufacturing costs and failure rates;

[0006] 3. Positioning relies on electronic sensors: Existing equipment mostly uses photoelectric or magnetic induction positioning, which is easily affected by oil stains and electromagnetic interference in the workshop, resulting in positioning drift.

[0007] In summary, existing dual-station screen printing machines suffer from key issues such as poor synchronization, high cost, complex structure, and poor reliability of electronic positioning systems in harsh environments due to dual independent lifting and traversing mechanisms. As a result, their practical application effectiveness is greatly reduced, and they fail to effectively address the industry's demand for efficient, stable, and low-cost screen printing production.

[0008] Therefore, there is an urgent need for a printing equipment that can achieve rigid synchronization between two workstations, is low-cost, and is resistant to interference. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides a dual-station running table printing machine that enables two stations to simultaneously carry screen printing plates, supports parallel operation of the two stations, significantly improves production efficiency, and reduces equipment manufacturing costs.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A dual-station running table printing machine includes a running table frame, a travel slide rail, and a screen printing device. The running table frame is movably connected to the upper part of the travel slide rail via a sliding mechanism and moves reciprocally along it. Several sensing components are provided on the side of the travel slide rail. It also includes a longitudinal main beam, two transverse main beams, and a screen printing plate fixing assembly. The longitudinal main beam is fixed to the upper part of the running table frame, and the two transverse main beams are movably connected to both sides of the longitudinal main beam via a lifting mechanism. Each transverse main beam is equipped with a screen printing device and a screen printing plate fixing assembly. The screen printing device is movably connected to the upper part of the transverse main beam via a transverse movement mechanism. The two sets of screen printing plate fixing assemblies jointly fix one screen printing plate. The screen printing plate is equipped with a sensing component. When the running table frame moves to a predetermined station, the sensing component abuts against the corresponding sensing component to achieve positioning.

[0012] Furthermore, the sensing component is an upright columnar or square metal body, and several sensing components are arranged at equal intervals on the side of the travel slide rail; the sensing component is a strip-shaped or sheet-shaped metal body that matches the contact surface of the sensing component.

[0013] Furthermore, the contact surface between the sensing component and the sensing component is a plane or an arc surface.

[0014] Furthermore, the lifting mechanism is a single-drive structure that synchronously drives the two transverse main beams to rise and fall; the lifting mechanism includes a servo motor and a lifting slide that is driven by the servo motor to move along a linear module, and the two longitudinal main beams are respectively fixed on the lifting slide.

[0015] Furthermore, the transverse mechanism is a single-drive structure that synchronously drives two screen printing devices laterally; the transverse mechanism includes a servo motor and a screen printing slide that is driven by the servo motor to move along a linear module, and the two screen printing devices are respectively fixed on the screen printing slide.

[0016] Furthermore, the screen printing device is located between the screen printing plate fixing components, which are either fixedly mounted on the upper part of the transverse main beam or movably connected to the linear module of the transverse movement mechanism via a slide table.

[0017] Compared with existing technologies, the technical solution of this patent has the following advantages:

[0018] 1. By using two transverse main beams and the screen printing devices and screen printing plate fixing components on them, two workstations can be synchronously loaded with screen printing plates, supporting parallel operation of two workstations and significantly improving production efficiency. The transverse movement mechanism is a single-drive structure, synchronously driving the two screen printing devices laterally; ensuring that the two screen printing devices move synchronously laterally and that the squeegeeing actions of the two workstations are consistent. The longitudinal main beam is fixed to the running table frame, and the transverse main beams are movably connected through a lifting mechanism. The lifting mechanism is a single-drive structure, synchronously driving the two transverse main beams to lift and lower, so that the screen printing plates of the two workstations are lifted and lowered synchronously, avoiding the problem of asynchronous action caused by traditional separate lifting and transverse movement. This solves the problem that existing technologies require separate design of lifting mechanisms on each set of printing frame fixing components, reducing equipment manufacturing costs while achieving synchronization of printing frame fixing components on two workstations.

[0019] 2. The single-drive lifting and traversing mechanism ensures complete synchronization of the two workstations, eliminating the cumulative errors caused by traditional multi-drive systems and guaranteeing the consistency of the screen-printed patterns. The mechanical contact design between the sensing and receiving components achieves physical contact positioning when the running table moves to the workstation, replacing electronic sensors, resulting in a simple structure and strong anti-interference capabilities.

[0020] 3. While improving production efficiency, it solves the industry pain points of poor synchronization, high cost and insufficient positioning accuracy of multi-station equipment, and realizes efficient, stable and low-cost screen printing operations. Attached Figure Description

[0027] 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.

[0028] See Figure 1-5 As shown, this embodiment provides a dual-station running table printing machine, including a running table frame 1, a travel slide rail 3, and a screen printing device 4; wherein the screen printing device 4 is a known technology and will not be described in detail here. The running table 1 is movably connected to the upper part of the travel slide rail 3 via a sliding mechanism and moves back and forth along it. Several sensing components 2 are provided on the side of the travel slide rail 3. It also includes a longitudinal main beam 5, two transverse main beams 6 and a screen printing plate fixing assembly 7. The longitudinal main beam 5 is fixed to the upper part of the running table 1, and the two transverse main beams 6 are movably connected to both sides of the longitudinal main beam 5 via a lifting mechanism 10. Each transverse main beam 6 is equipped with a screen printing device 4 and a screen printing plate fixing assembly 7. The screen printing device 4 is movably connected to the upper part of the transverse main beam 6 via a transverse movement mechanism 11. The two sets of screen printing plate fixing assemblies 7 jointly fix a screen printing plate 8. The screen printing plate fixing assembly 7 includes, but is not limited to, a fixing frame and a fixing plate. The fixing frame is fixedly connected to the fixing plate, and the fixing plate is then locked to the screen printing plate 8 by screws. A sensing component 9 is provided on one side of the screen printing plate 8. When the running table 1 moves to the predetermined work position, the sensing component 9 abuts against the corresponding sensing component 2 to achieve positioning.

[0029] This dual-station trolley printing machine uses two transverse main beams 6 and their respective screen printing devices 4 and screen printing plate fixing components 7 to achieve synchronous loading of screen printing plates 8 at two stations, supporting parallel operation of two stations and significantly improving production efficiency. The longitudinal main beam 5 is fixed to the trolley frame 1, and the transverse main beams 6 are movably connected via a lifting mechanism 10, enabling synchronous lifting and lowering of the screen printing plates at both stations, avoiding the asynchronous movement problems caused by traditional separate lifting mechanisms. This solves the problem of requiring separate lifting mechanisms for each set of printing frame fixing components 7 in existing technologies, reducing equipment manufacturing costs while achieving synchronization of the printing frame fixing components 7 at both stations. The mechanical contact design between the sensing component 9 and the sensing component 2 achieves physical contact positioning when the trolley frame 1 moves to the station, replacing electronic sensors, resulting in a simple structure and strong anti-interference capabilities. While improving production efficiency, it solves the industry pain points of poor synchronization, high cost, and insufficient positioning accuracy in multi-station equipment, achieving efficient, stable, and low-cost screen printing operations.

[0030] The sensing component 2 is a vertically arranged columnar or square metal body, and several sensing components 2 are arranged at equal intervals on the side of the travel slide rail 2; the sensing component 9 is a strip-shaped or sheet-shaped metal body that matches the contact surface of the sensing component 2. The contact surface between the sensing component 9 and the sensing component 2 is a plane or an arc surface. The sensing components 2 are equidistantly arranged metal columns or cubes, and the sensing components 9 are strip-shaped or sheet-shaped metal bodies. When the running platform 1 moves to the work position, it achieves physical contact positioning, replacing electronic sensors. The positioning force is directly transmitted through rigid body contact, and the positioning accuracy remains stable over a long period of time.

[0031] The lifting mechanism 10 is a single-drive structure that synchronously drives the two transverse main beams 6 to rise and fall. The lifting mechanism 10 includes a servo motor and a lifting slide 101 driven by the servo motor to move 100 along a linear module. The two longitudinal main beams 5 are respectively fixed on the lifting slide 101. The lifting mechanism 10 uses a single servo motor to drive the lifting slide 101, which drives the two transverse main beams 6 to rise and fall rigidly and synchronously, completely eliminating the height difference between the two workstations and ensuring the synchronization of screen printing operations at the two workstations; at the same time, it reduces the number of drive components, lowers the failure rate and cost.

[0032] The transverse mechanism 11 is a single-drive structure that synchronously drives the two screen printing devices 4 laterally. The transverse mechanism 11 includes a servo motor and a screen printing slide 111 driven by the servo motor to move along the linear module 110. The two screen printing devices 4 are respectively fixed on the screen printing slide 111. The transverse mechanism 11 drives the screen printing slide 111 by a single servo motor, so that the two screen printing devices 4 move laterally synchronously, ensuring the consistency of the dual-station squeegee operation.

[0033] The screen printing device 4 is located between the screen printing plate fixing components 7. The screen printing plate fixing components 7 are either fixedly mounted on the upper part of the transverse main beam 6 or movably connected to the linear module 110 of the transverse movement mechanism 11 via a slide table. The screen printing plate fixing components 7 can be fixed to the transverse main beam 6 or connected to the transverse movement mechanism 11 via the slide table 112, providing two installation modes: fixed mode: simplified structure, suitable for standard screen printing plates; slide table mode: supports fine adjustment of the screen printing plate, adapting to different sized substrates.

[0034] Working principle: Driven by the sliding mechanism, the running table 1 moves forward along the travel slide rail 3 to a predetermined position and then stops. The lifting mechanism 10 starts, driving the transverse main beam 6 on the dual workstations to descend to a set height, so that the sensing component 9 approaches the sensing component 2 on the side of the travel slide rail 3. It should be noted that when the transverse main beam 6 is not descending, the sensing component 9 is at the higher position of the sensing component 2, so the running table 1 will not collide with the sensing component 2 when it moves horizontally. The running table 1 moves slightly under the drive of the sliding mechanism until the sensing component 9 abuts against the sensing component 2 of the current workstation, and then stops moving to complete the precise positioning. Driven by the transverse mechanism 11, the screen printing device 4 performs reciprocating screen printing in the area of ​​the screen printing plate 8. It should be noted that while the sensing component 9 descends, the screen printing plate fixing component 7 also descends simultaneously, pressing the screen printing plate 8 against the material to be screen printed before screen printing. After the screen printing is completed, the sliding mechanism reverses and drives the running table 1 to move laterally, causing the sensing component 9 to disengage from the sensing component 2. The lifting mechanism 10 drives the transverse main beam 6 to move upward and reset to the initial height. The running table 1 continues to move forward to the corresponding position of the next sensing component 2, repeating the above steps to complete the positioning and screen printing of the screen printing plate 8. After all running table operations are completed, the running table 1 returns along the travel rail under the drive of the sliding mechanism, resetting to the initial position.
