Description

Technical Field

[0001] This utility model relates to the field of screen printing machine technology, and in particular to a fully automatic double-sided screen printing machine. Background Technology

[0002] Screen printing is a type of stencil printing. Its principle is that perforations are made on the printing plate (paper film) or other plate base to allow ink to pass through. During printing, a certain pressure is applied to force the ink through the perforations of the stencil to transfer it onto the substrate (paper, ceramics, etc.) to form images or text.

[0003] Chinese Patent CN220883699U discloses a fully automatic double-sided screen printing machine, including a screen printing platform and processing elements. A protective shell is provided on one side of the screen printing platform. Two sets of dust removal rollers are located inside a limiting frame. Two sets of drive motors are located on one side wall of the limiting frame. A rectangular plate is located at the bottom of the inner side of the protective shell. Two sets of grooves are formed on the surface of the rectangular plate. Two sets of first electric push rods are located on the surface of the rectangular plate. Each output end of the two sets of first electric push rods is connected to a set of anti-slip pads. A conveyor belt is embedded in the surface of the protective shell. A set of second electric push rods is located on opposite sides of the inner wall of the protective shell. Rotary grippers are connected to the output ends of the two sets of second electric push rods. A drying mechanism is connected through the top of the protective shell. This embodiment improves the flexibility of double-sided printing while reducing production costs.

[0004] Fully automatic double-sided screen printing machines use dust removal rollers to remove dust from the substrate. However, after dust removal, when the substrate is transferred to the screen printing platform, the dust floating on the screen printing platform may fall onto the surface of the substrate. The existing cleaning structure is inconvenient to clean the dust floating on the screen printing platform. The dust floats and falls onto the surface of the substrate, causing the surface of the substrate to be contaminated with impurities again, which in turn affects the screen printing effect of the graphics on the substrate and reduces the performance of the fully automatic double-sided screen printing machine.

[0015] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0016] Example 1: As Figure 1 - Figure 4As shown, this utility model proposes a fully automatic double-sided screen printing machine, comprising: a screen printing platform 1, a connecting component, a protective shell 3, and a cleaning component; the connecting component is connected to the screen printing platform 1; the connecting component includes a mounting shell 2, a mounting box 201, a dust suction hood 202, a mounting pipe 203, a connecting pipe 204, an exhaust fan 205, and a mounting component; the inner wall of the mounting shell 2 is connected to the mounting box 201, the lower part of the mounting box 201 is connected to the dust suction hood 202, and the upper part is connected to the mounting pipe 203, the mounting pipe 203 passes through the mounting shell 2 and is connected to the connecting pipe 204, the connecting pipe 204 is connected to the exhaust fan 205, and the mounting component is connected to the mounting shell 2; the protective shell 3 is connected to one side of the screen printing platform 1; the cleaning component is connected to one side of the protective shell 3. An annular groove is provided on the inner side of the dust hood 202. The filter structure is designed as a circular filter cartridge that fits the groove. An elastic sealing ring is set on the edge of the filter cartridge. During installation, the filter cartridge is directly inserted into the annular groove. The sealing ring can fit tightly against the inner wall of the groove to prevent unfiltered airflow from leaking in from the gaps. A metal filter screen is connected to the inner wall of the circular filter cartridge to prevent dust and other impurities from entering the connecting component structure. By using the exhaust fan 205 and other components of the connecting component in conjunction, the suction force generated by the exhaust fan 205 continuously absorbs the dust floating above the screen printing platform 1, preventing dust from falling onto the surface of the substrate during the screen printing process, thus avoiding secondary pollution. This further ensures the clarity and integrity of the screen printing of the substrate graphics and improves the performance of the fully automatic double-sided screen printing machine. A rubber sealing gasket can be added to the connection between the mounting box 201 and the dust hood 202 to prevent the seal from failing due to long-term use, ensuring that the suction force generated by the exhaust fan 205 is concentrated on the area above the screen printing platform 1, improving the dust adsorption efficiency.

[0017] Further explanation: The mounting components include a mounting rod 206, a reinforcing plate 207, and a positioning block 208. The mounting rod 206 is connected to both sides of the outer wall of one end of the mounting housing 2, the reinforcing plate 207 is connected to the other end of the mounting housing 2, and the positioning block 208 is connected below the reinforcing plate 207, with the positioning block 208 connected to the positioning groove 303. The mounting rod 206 is provided with mounting holes and is connected to both sides of the outer wall of the screen printing platform 1. Corresponding threaded holes are reserved on both sides of the screen printing platform 1. By using high-strength screws, one end of the screw passes through the mounting holes and the threaded holes for threaded connection, allowing the mounting rod 206 and both sides of the screen printing platform 1 to be fixedly and detachably connected, which is simple to operate and easy to use.

[0018] Further explanation: The correction component includes a connecting bracket 406, a telescopic cylinder 407, a fixing plate 408, and a correction rod 409. The connecting bracket 406 is connected to both sides of the limiting frame 4. The connecting bracket 406 is connected to the telescopic cylinder 407. The driving ends of the telescopic cylinder 407 are connected to the fixing plate 408. The fixing plate 408 is connected to the correction rod 409. The correction rod 409 is connected between the upper dust removal roller 401 and the lower dust removal roller 402. The surface of the correction rod 409 can be covered with a silicone protective layer. When it comes into contact with the side of the substrate, it can ensure the limiting effect and avoid scratching the surface of the substrate. The lower part of the limiting frame 4 is connected to the support base plate 5 through a support rod. The support base plate 5 is connected to one side of the screen printing platform 1. When the substrate processing element is being transported, the telescopic cylinder 407 is activated, and its drive end drives the fixed plate 408 and the correction rod 409 to move synchronously. Through the contact between the correction rod 409 and the side of the substrate processing element, the substrate processing element is limited to pass through the cleaning component, so as to avoid poor cleaning effect caused by displacement of the substrate processing element during the transport process.

[0019] Example 2: Figure 1 and Figure 2 As shown, this utility model proposes a fully automatic double-sided screen printing machine. Based on the above embodiments, this embodiment also details the specific components such as the screen printing platform 1 and the protective shell 3, as well as their cooperation method.

[0020] Further explanation: A screen printing mechanism 6 is connected above the screen printing platform 1. Moving rods 7 are connected to both sides of the screen printing mechanism 6, and each moving rod 7 is connected to a limiting moving groove. The limiting moving grooves are located on opposite sides of the screen printing platform 1, and the two sets of limiting moving grooves are symmetrically arranged with the center line of the screen printing mechanism 6 as the center. The substrate is transported to the screen printing platform 1 via a conveyor belt. The moving rods 7 move along the limiting moving grooves, driving the screen printing mechanism 6 to move and perform screen printing on the substrate. A rectangular plate 301 is connected to the bottom of the inner part of the protective shell 3. A conveyor belt is embedded in the surface of the protective shell 3. A drying mechanism 302 is connected through the top of the protective shell 3, and a positioning groove 303 is provided near the end of the mounting shell 2. After the substrate processing element is screen printed, the drying mechanism 302 dries it. After drying, the processing element is flipped over by two sets of rotating grippers. The processing element is then transported back to the surface of the screen printing platform 1 by a conveyor belt for printing on the other side. The rectangular plate 301 has two sets of grooves and two sets of electric push rods a. The output ends of the electric push rods a are connected to anti-slip pads. The protective shell 3 has electric push rods b on both sides. The output ends of the electric push rods b are connected to the rotating grippers. The processing element is raised to the horizontal height of the two sets of rotating grippers by the electric push rods a, so that the processing element is flipped over by the two sets of rotating grippers. The protective shell 3 and other structures are built based on existing mature technologies, so there is no need to elaborate on them here.

[0021] To further explain, the cleaning assembly includes a limiting frame 4, an upper dust removal roller 401, a lower dust removal roller 402, a rotating rod 403, a gear 404, a servo motor 405, and a correction component; the inner wall of the limiting frame 4 is connected to the upper dust removal roller 401 and the lower dust removal roller 402, and the upper dust removal roller 401 and the lower dust removal roller 402 are respectively connected to the outer surface of the rotating rod 403. The two ends of the rotating rod 403 rotate and are connected to the limiting frame 4. The outer wall of one end of the rotating rod 403 is respectively connected to the gear 404, and the lower rotating rod 403 is connected to the output shaft of the servo motor 405. The upper dust removal roller 401 and the lower dust removal roller 402 are covered with high-density microfiber cloth covers. The cloth covers are connected to the roller body by Velcro. When the cloth covers have absorbed a lot of dust, they can be directly torn off and replaced without disassembling the entire dust removal roller, thus reducing maintenance costs. Two gears 404 mesh with each other. When the servo motor 405 drives the lower rotating rod 403 to rotate, the meshing transmission of the gears 404 drives the upper rotating rod 403 to rotate synchronously in the opposite direction, so that the upper dust removal roller 401 and the lower dust removal roller 402 can rotate in opposite directions, thereby synchronously cleaning the upper and lower surfaces of the substrate passing between them.

[0022] The working principle of this utility model is as follows: During use, the transmission belt transports the cleaned substrate processing element to the surface of the screen printing platform 1 for graphic printing. During the screen printing process, the exhaust fan 205 is already in operation. The dust suction end of the exhaust fan 205 is connected to the mounting pipe 203 through the connecting pipe 204. The mounting pipe 203 is connected to the mounting box 201, and the mounting box 201 is connected to the dust suction hood 202. Thus, through the cooperation of the dust suction hood 202, the mounting box 201, the mounting pipe 203, the connecting pipe 204, and the dust suction hood 202, the generated suction force can continuously absorb the dust floating on the screen printing platform 1. The exhaust end of the exhaust fan 205 is then processed by the workshop dust treatment system, thereby avoiding secondary pollution of the substrate during the transportation and printing process. This facilitates the processing of substrate processing elements by the fully automatic double-sided screen printing machine. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0023] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
